Opis:

The pandemic is not in favour of any scientific symposia and conferences, especially the international ones. Many have been cancelled, while some managed to migrate into the Internet. This was the case of the conference organised by the Progect Network for the Study of Progressive Rock, entitled ‘Progressive Rock and Metal: Towards a Contemporary Understanding’ and originally scheduled to take place in May 2020 in Ottawa, Canada. Due to pandemic restrictions, the event was first moved to 2021 to finally, a few months later, offer a fully remote and “virtual” formula; hence the name change to Virtual Progect.

Opis:

Multiple sclerosis (MS) is a demyelinating, inflammatory, autoimmune disease of the central nervous system which affects most commonly young adults. It has wide spectrum of clinical and radiological presentations with relapses or steady progression. Recent years have brought new reports on the pathogenesis of MS. This systematized the current MS classification and created new parameters describing the course of the disease, such as activity and progression. Attention has been paid to the need for new drugs that focus on the treatment of progressive MS. Until now, the primary and secondary progressive MS have been somewhat forgotten, and most of modifying-disease drugs have been registered in the treatment of relapsing-remitting subtype. In recent years, not only new drug has been registered for the treatment of progressive MS (ocrelizumab) and another one is planned to be approved soon (siponimod), but also indications of old medicines (interferon-beta1b, cladribine, mitoxantrone, cyclophosphamide, azathioprine) have been extended. Despite intensive development, there is still a great need to seek new drugs that will stop the progression of disability in MS patients.

After a prolonged absence of the topic of education reformers in the public discussion nowadays it’s obviously an increased interest in their approaches and models of performance. The theoretical reflections of the progressive education based on the ideas of the creative power of the child figuring in a mythical, romantic-coded image of the child as a genius. This conception was in opposite to the rigid forms of teaching, to every automatism of learning, against the authoritarian treating of teachers with students.

Prison penalty, progressive penitentiary system

Opis:

The article is concentrated on the procedure of carrying out the prison penalty in 1918–1938. You can distinguish two periods important for Polish penitentiary law in these times. The first of them was marked by taking out prisons from the occupants’ hands and by building grounds of Polish penitentiary system. The important step on this field was done on March 7th, 1928, when the President’s decree on system of prison organization was passed. This decree opens new period in Polish penitentiary system, because the progressive system of carrying out the prison penalty was introduced to Polish law then. The model was in accordance with the European standards and was taking into account the resolutions of penitentiary congresses of this time. However, the reality of prisons However, the reality of prisons was significantly different. The progressive system was introduced only with small group The progressive system was introduced only with small group of sentenced persons. More than 70% of prisoners had no work and they were kept in crowded prisons with no sufficient hygienic conditions. The problem of crowded prisons was only partially solved by the amnesty acts.

Opis:

The current article is an attempt by the authors to present a bioethical case, or rather a search being undertaken to develop tools to interpret the novel ontological realm which has been created, and continues to be transformed in real time, by the COVID19 pandemic and its aftermath. The ontological realm is new, but the physical features of the world and the human in it are partially constants and identical to the previous realm parameters, the pre-COVID19 space-time. The question of existence in the new ontological realm is...how can the continuum of Homo sapiens and its existence be sustained in this new realm? The tools being developed use of previous information and knowledge of the members of Homo sapiens as a starting point and source of metaphors as tools to facilitate existence in the new realm. In this way, existing knowledge, which is held by individual members of Homo sapiens, and which exists and continues being created in the continuum of Homo sapiens, can be the foundation for the creation of new knowledge about the post-COVID19 realm and the individual and collective comprehension of humans of it and in it. Conceptual metaphors, the creation of compound metaphor and the prospective dialectic are suggested by authors as a possible epistemic implementation mechanisms in this context. The adaptation of humanity, its imagination and some professions are used to demonstrate the case for the ‘new science of human existence’ in the post-COVID19 world.

Opis:

The paper looks at personal income tax (PIT) in Poland from the perspective of its progressiveness, redistribution effect and influence on prosperity. Household budget surveys carried out by the Central Statistical Office (GUS) in 2003-2005 are the main source of data. The statistical and econometric analysis included in the paper takes into account some basic measures of tax progression. The author also uses a decomposition approach to determine PIT’s effect on the average tax rate in the country. The empirical study conducted by Aksman shows that even though Poland’s PIT is progressive, its overall redistribution effect is not very strong; in the analyzed period it reduced household income inequalities by only 5.22% on average. This is mainly due to a low effective tax rate, Aksman says. What’s more, PIT leads to a decline in prosperity measured with the Sen index; in the analyzed period of time prosperity declined by 11.23% annually on average. With PIT, “poverty aversion” is stronger than “inequality aversion,” the author says, which means that the loss of prosperity resulting from the fall in average income is greater than the increase of prosperity resulting from reduced income disparities.

Opis:

Horizontal crash at road and rail vehicles generates human and material injuries, many of them with important negative effects. Damper in bumper a known solution for vehicles protection at crash is realized with different damping devices, from passive elements to actuators. Usually the devices are tunedfor 5 km/h crash speed. After collision the passive solutions destroy and must be removed with other new devices. The solutions using standard shock absorbers and actuators are improper the first dissipating insufficient energy and actuators being more expensive and having a long reaction time so the damping coefficient changing is realized in too low steps. VZN damper concept granted with European Patent EP l 190 184 and Romanian Patent RO l 18546, characterized by progressive damping coefficients with the stroke is a great opportunity to realize simple and cheap protection at crash, due to its capacity to realize constant damping force without mechanisms and electronics. li is necessary only to tune accordingly VZN damping characteristic to this desiderate. VZN concept consist of u piston rod attached to a piston without valves moving inside inner cylinder close at both ends and filled at rebound and compression by specific fllling valves placed in upper /bottom lids or on the ends of the inner cylinder. The damping effect is realized by valves or in cheap solution by metering orifices (holes/slots) placed sideways inner cylinder in convenient position. Due to this structure VZN tuning for constant damping force at different piston speed can be realize both with identical metering holes/slots placed at optimal distances, or placing metering holes/slots of different areas at eąual distances. The numbers of metering holes/slots are enough such the steps speed evolution be practical continuous and thus the damping force be practical constant. The VZN behaviour is increased by new components e.g. levelling pistons, double guiding elements and balancing solutions. Paper presents the theory used to dimension VZN damper placing metering orifices at eąual distances, a practical device with levelling piston and simulation comparative to standard one. The standard damper dissipates 30-40% lower energy comparative to VZN one. This means in the same situation in which VZN damper reduces constant speed from 30, respectively 20 [km/h] to zero, the standard dampers reduces speed up to 14, respectively 11 [km/h], then collapsing the vehicle.

Opis:

Traditional masculinity has been thoroughly explored in psychological research, but its counterpart, progressive masculinity, has undergone relatively little scientific investigation. To determine whether this lack of attention to or understanding of progressive masculinity is mirrored more largely in mainstream culture, we examined how men and women conceptualize and experience gender roles in their everyday lives. Participants were randomly assigned to describe a time in which they had behaved either traditionally or progressively with regard to their gender. Over 80% of men and women in the traditional condition and women in the progressive condition provided condition-appropriate examples. However, men in the progressive condition only provided progressive examples 17% of the time, suggesting that many men may not have an understanding of progressive masculinity. Additional themes, implications, and directions for research on progressive masculinity are discussed.

The paper presents the implementation of methods for progressive mesh encoding. The described implementation is a modification of the software published in 2008 by Zhao He, which is based on studies by Michael Garland and Hugues Hoppe. We focused on improving the performance of the software. In particular we modified the data structures to ensure their better indexing, which significantly improved the computational complexity of the algorithm. We also implemented the support for simplified meshes with textures. The authors present the comparison of the performance of these methods in relation to the original He Zhao's algorithm. The performance of progressive mesh encoding in our implementation was significantly improved.
W artykule przedstawiono implementację algorytmu kodowania siatek trójwymiarowych do postaci progresywnej. Opisana implementacja jest rozwinięciem oprogramowania opublikowanego w 2008 roku przez He Zhao, które bazuje na opracowaniach Michaela Garlanda [1] oraz Huguesa Hoppe [5]. Celem autorów było wykorzystanie prezentowanego oprogramowania do kodowania siatek o znacznym rozmiarze, reprezentujących między innymi skany eksponatów muzealnych lub modele uzyskane w wyniku obrazowania medycznego. Wobu przypadkach kodowanie do postaci progresywnej ma na celu zapewnienie efektywnego przesyłania i szybkiej prezentacji siatek na różnych poziomach wizualizacji szczegółów (levels of detals). Jednocześnie powinno ono umożliwiać szybkie odzyskanie oryginalnej siatki w razie potrzeby wykonania pomiarów. Skupiono się na poprawie szybkości działania algorytmu poprzez wprowadzenie struktur danych zapewniających ich odpowiednie indeksowanie, co znacząco poprawiło złożoność obliczeniową. W porównaniu do możliwości oferowanych przez oprogramowanie He Zhao została także dodana uproszczona obsługa progresywnego kodowania siatek z teksturami. Przeprowadzono i przedstawiono w artykule porównanie czasów działania oprogramowania w prezentowanej wersji oraz w implementacji He Zhao i wykazano, że wydajność czasowa uległa znaczącej poprawie.

The non-linear structural analysis is considered as a basic design procedure, which is used for checking of the structural robustness in accidental design situation. It is explained by following reason: a non-linear structural analysis based on realistic constitutive relations for basic variables (average values) makes possible a simulation of a real structural behavior. It should be pointed that, implementation of the non-linear structural analysis in design of concrete structures requires an alternate approach to safety verification. The paper presents a new approach to safety format for non-linear analysis of RC structures subjected to accidental loads.

Nowadays, when schools are closing and teachers are made redundant, a question arises whether the current educational system and the teaching methods or the knowledge and skills which people leave school with are adequate. Now, as never before, students and em-ployers realize how important practical skills are in the labor market. Where are schools and universities in meeting this need? Do schools answer the natural needs people have for self--development? Does the educational system stimulate development of individuals interests? Unfortunately, I think the answer to a lot of these questions would be negative. Yet, if so, it is time we fi nd a way to offer something more, not only to young people, but also to adults who want to explore the area of their interests by taking the trouble to obtain further degrees. One of the solutions to the urgent needs for the educational system is a pragmatic approach towards learning and teaching.

Opis:

The paper is founded on the distinction between traditional school represented by Johann F. Herbart and progressive school here represented by Bell Hooks. The main purpose of this article is to describe specific characteristics of these two educational models taking into account changes within them. Foucault’s disciplinary power schema provides methodological tools for better apprehension of the location of power in the classroom. In particular, the concept of exam mentioned by Foucault in his Discipline and Punish: The Birth of the Prison has great importance for better understanding of changes within the two aforementioned educational models and student-teacher relations. It appears that power is a fundamental element in these relations, which is exemplified by the presence of the hidden curriculum and how it affects students. Conceiving teaching as a technical activity the autor argues that the way this power is performed depends on the teacher’s character, skills and will.

Opis:

Objectives: The aim of the study was the epidemiological analysis and evaluation of selected clinical and sociodemographic factors in Polish patients with primary progressive multiple sclerosis. Methods: The study included patients from 7 provinces in central and eastern Poland registered in the Registry of Patients with Multiple Sclerosis on 31 December 2016. The incidence of various forms of the disease was compared, and clinical, demographic and social disparities between relapsing-remitting and primary progressive multiple sclerosis were analysed. Results: Of 3,199 registered patients, 2,188 persons (66.2%) had the relapsing-remitting form of multiple sclerosis, 774 (24.2%) had the secondary progressive type and 307 (9.6%) suffered from primary progressive disease. The first symptoms of primary progressive multiple sclerosis appeared almost 10 years later than in patients with the relapsing-remitting type (39.2 ± 11.4 vs. 29.8 ± 9.8). The period from the first symptoms to diagnosis was more than twice as long in patients with primary progressive multiple sclerosis (5.8 ± 3.4) as in those with relapsing-remitting disease (2.4 ± 1.6). The average degree of disability in the Expanded Disability Status Scale was similar and amounted to 3.2 ± 2.1 for relapsing-remitting and 3.6 ± 2.4 for primary progressive multiple sclerosis. The relapsing-remitting form was observed more often in women (2.4:1), and the primary progressive form appeared with equal frequency in both sexes (1:1). Disease-modifying treatment was received by 34% of patients with relapsing-remitting and in only 1.9% of patients with primary progressive multiple sclerosis. Conclusions: The primary progressive form affects approximately 10% of Polish patients with multiple sclerosis. The first symptoms appear at about 40 years of age with equal frequency in both sexes, and its diagnosis takes more than twice as much time as in the case of relapsing-remitting multiple sclerosis.

Metody: Do badania włączono pacjentów zamieszkujących 7 województw środkowej i wschodniej Polski, objętych Rejestrem Chorych ze Stwardnieniem Rozsianym w dniu 31 grudnia 2016 roku. Porównywano częstość występowania poszczególnych postaci choroby, a także analizowano różnice kliniczne, demograficzne i społeczne między postacią rzutowo-remisyjną i pierwotnie postępującą stwardnienia rozsianego. Wyniki: Spośród 3199 zarejestrowanych pacjentów postać rzutowo-remisyjną miało 2188 osób (66,2%), wtórnie postępującą – 774 (24,2%), a pierwotnie postępującą – 307 (9,6%). Pierwsze objawy postaci pierwotnie postępującej stwardnienia rozsianego pojawiały się prawie 10 lat później niż w przypadku postaci rzutowo-remisyjnej (39,2 ± 11,4 vs 29,8 ± 9,8). U chorych z postacią pierwotnie postępującą okres od pierwszych objawów do rozpoznania był ponad dwukrotnie dłuższy (5,8 ± 3,4) niż u tych z postacią rzutowo-remisyjną (2,4 ± 1,6). Średni stopień niesprawności w Rozszerzonej Skali Niewydolności Ruchowej (Expanded Disability Status Scale, EDSS) był zbliżony i wynosił 3,2 ± 2,1 dla postaci rzutowo- -remisyjnej i 3,6 ± 2,4 dla pierwotnie postępującej. Postać rzutowo-remisyjną częściej stwierdzano u kobiet (2,4:1), natomiast postać pierwotnie postępująca występowała z równą częstością u obu płci (1:1). Leczenie modyfikujące przebieg choroby otrzymywało 34% osób z postacią rzutowo-remisyjną i tylko 1,9% z pierwotnie postępującą. Wnioski: Postać pierwotnie postępująca występuje u około 10% polskich pacjentów ze stwardnieniem rozsianym, pierwsze objawy pojawiają się około 40. roku życia z jednakową częstością u obu płci, a diagnoza postaci pierwotnie postępującej zajmuje ponad dwukrotnie więcej czasu niż rozpoznanie postaci rzutowo-remisyjnej.

Opis:

In recent times, German as a language with a well-functioning tense system is developing a special progressive form, marking actions and processes which are continual and not yet terminated. There is a variety of forms like beim Arbeiten or gerade im Begriff sein zu arbeiten, but most usual and by far most grammaticalised is the am-progressive (er ist am Arbeiten, “he is working”). In this paper the restrictions which still exist are discussed. They are limited, but although they are not entirely accepted in standard German, the range of these constructions is extensive. In spite of this fact, the German language does not tend to develop general aspectual markers. A comparison with English shows this clearly. However, in its early periods the German language had overt aspectual characteristics. Especially constructions with the present participle and the auxiliary verbs sein and warden could function as aspect partners. These constructions gradually disappeared at the end of Middle High German. Thus, modern German has only very few aspectual markers, which are restricted to progressive constructions verbalizing actions and processes in actual situations.

Opis:

This paper presents a fully scalable image coding scheme based on the set partitioning in hierarchical trees (SPIHT) algorithm. The proposed algorithm, called fully scalable SPIHT (FS-SPIHT), adds the spatial scalability feature to the SPIHT algorithm. It provides this new functionality without sacrificing other important features of the original SPIHT bitstream such as: compression efficiency, full embeddedness and rate scalability. The flexible output bitstream of the FS-SPIHT encoder which consists of a set of embedded parts related to different resolutions and quality levels can be easily adapted (reordered) to given bandwidth and resolution requirements by a simple parser without decoding the bitstream. FS-SPIHT is a very good candidate for image communication over heterogenous networks which requires high degree of scalability from image coding systems.

Opis:

The progressive collapse of a space grid structure which has a large number of members and a large span is the focus of current research. Before the progressive collapse of the structure, there is a problem of instability of the members. In this paper, dynamic nonlinear analysis of a super-long span latticed steel arch structure is carried out to study its progressive collapse process using a Kinematic Hardening Plasticity constitutive model compiled by Vumat material subprogram in Abaqus, which takes into account instability of the members. Differences in the dynamic response process of the structure at the collapse moment and the failure sequence of the members using the member stability model and the material failure constitutive model are compared. Compared with the material failure constitutive model, when the member stability constitutive model is used, the proportion of compressive buckling members in the structural failure is higher, and the bearing capacity of the structure is lower when the initial failure occurs. The structure suffers from localized member compressive failure rather than material yielding, which leads to the progressive collapse of the structure.

The gear which is the central safety element of the friction drive lift during braking is exposed to overloading connected with changeable weight which loads the lift braking system. In the article the results of numerical analysis for braking process of CHP 2000 type progressive gear distinguished by an innovative design have been presented. The numerical analysis was conducted with the use of a simulation of the gear roller displacement depending on changeable loading with the support of Abaqus/CAE software. Displacement of the gear roller from the neutral position in which the gear starts loosing energy of speeding up weight to zero was simulated. The results obtained from computer simulations were verified on the basis of a physical experiment at the bench station created to verify braking parameters of the gears with the use of free fall method.

Opis:

Passive security at crash is an importami problem both for road, and aerial vehicles, first case at horizontal collision and second at vertical one, on landing operation on ground or deck. Both generate human and material injuries, many of them with important negative effects. Damper in bumper a known solution for vehicles protection at crash is realized with different damping devices, from passive elements to actuators. Usually the devices are tuned for 5 km/h crash speed and after collision the passive solutions destroy and must be replaced with other new devices. The solutions using standard shock absorbers and actuators are improper the first dissipating insufficient energy and actuators being more expensive and having a long reaction time so the damping coefficient changing is realized in too low steps. VZN damper concept granted with European Patent EP l 190 184 and Romanian Patent RO l 18546, characterized by progressive damping coefficients with the stroke assures protection at crash, due to its capacity to realize constant damping force without mechanisms and electronics, tuning damping characteristic to this desiderate. The paper presents the differences between the energy must to be dissipated at the same crash speed in horizontal and vertical situation, it being increased at vertical situation, due to the gravity. The same paper evaluates the advantages confers by VZN damper concept comparative to standard one, for both vertical and horizontal collision and concludes the VZN one is better 39% at vertical crash and 25% at horizontal crash comparative to standard one, due to its efficient dissipating system.

Opis:

An additional recovery of coking coal middlings can be utilized for increasing of the concentrate yield of coking coal. A combined flow sheet of comminution and flotation can realize this target. To investigate the effect of grinding process on further flotation of ground products, progressive release flotation tests were used to compare with the float-sink tests, which were regarded as a criterion. Coal middlings were ground by wet-milling with iron balls to <0.5 mm. Curves of ash vs. cumulative yields of sized products indicated that the concentrate yield of coal separated by progressive release flotation was lower than that of coal benefited by the float-sink test, with the same ash for four size fractions (0.5-0.25 mm, 0.25-0.125 mm, 0.125-0.074 mm and <0.074 mm). Distributions of elements conducted by energy disperse spectroscopy (EDX) showed that associated kaolinite was liberated and exposed on the surface. It led to the shift of local surface property from hydrophobicity to hydrophilicity. Meanwhile, analyses of chemical property performed by an X-Ray photoelectron spectrometer (XPS) depicted that the hydrophilic mineral FeOOH, which generated in the grinding process, was adsorbed on the coal surface. Flotation of the ground products were worsened due to the increase of hydrophilicity of the coal surface.

Opis:

The article presents the activities and selected views of the French educationalist Gaston Mialaret on the centenary of his birthday. He was a long-time professor at Faculté des Lettres et Sciences Humaines at the University of Caen. He combined the taste for empirical research with interest in philosophy. He continued and enriched the concepts of the New Education, especially the lasting importance of simultaneous research on the subsequent stages of child development and the implementation of education based on the assumptions of development pedagogy. He developed proposals for progressive educational reform presented in 1947 in the project “Le plan Langevin-Wallon”. On the background of the analysis of the changing role of education in the contemporary world, Mialaret showed the changing role of pedagogical studies and especially the new role of the teacher as an animator of educational acts and situations. The article emphasises the basic, in Mialaret’s opinion, the importance of the socalled active methods enabling the enrichment of personality at all levels of education and the development of the educational, intellectual, civic and cultural potential of each student.

Opis:

Kakwani and Lambert (1998) state three axioms which should be respected by an equitable tax system; then they propose a measurement system to evaluate at the same time the negative influences that axiom violations exert on the redistributive effect of taxes, and the potential equity of the tax system, which would be attained in absence of departures from equity. The authors calculate both the potential equity and the losses due to axiom violations, starting from the Kakwani (1977) progressivity index and the Kakwani (1984) decomposition of the redistributive effect. In this paper, we focus on the measure suggested by Kakwani and Lambert for the loss in potential equity, which is due to violations of the progressive principle: the authors’ measure is based on the tax rate re-ranking index, calculated with respect to the ranking of pre-tax income distribution. The aim of the paper is to achieve a better understanding of what Kakwani and Lambert’s measure actually represents, when it corrects the actual Kakwani progressivity index. The authors’ measure is first of all considered under its analytical aspects and then observed in different simulated tax systems. In order to better highlight its behaviour, simulations compare Kakwani and Lambert’s measure with the potential equity of a counterfactual tax distribution, which respects the progressive principle and preserves the overall tax revenue. The analysis presented in this article is performed by making use of the approach recently introduced by Pellegrino and Vernizzi (2013).

Due to self-acting variability of operating conditions during the work of lifting devices, it is fundamental for the gears to stop the cabin at any clearance height. The operating conditions are changed by dust contamination influencing a proper braking process of the gear. This article presents the independent tests results. The impact of progressive gear geometry on the braking distance both in variable operating conditions and variable loading is analyzed. The tests were conducted for the gear applied in short distance transportation devices. Changing operating conditions were obtained by using various lubricating agents. The following five types of the gears were used for the tests: ASG100, PP16, PR2000, KB160. CHP 2000 gear was tested as a new solution. The tests were conducted using a free fall method. The test results obtained from an experiment were approximated by using Savitzky-Golay method.

The paper presents an analysis and assessment of recorded accelerations acting on Hybrid III dummy during emergency braking of a passenger lift. The dummy was equipped with a system of three-axis accelerometers. The type of progressive safety gear that has the shortest time of reaction and the shortest effective braking distance in its group, was chosen for tests. The tests were carried out on an emplacement, which simulated the movement of passenger lift. Tests of emergency braking were performed at variable load of a cabin corresponding to the mass of different passengers number. The cabin was dispelled by the gravity force using its free-fall. During the braking, the values of accelerations effected on individual parts of dummy, were measured. Based on them and using HIC and Nij indexes, the impact of temporary accelerations on passenger’s health was determined.

Opis:

A theoretical ballistic analysis of tubular rocket propellants burning in the progressive mode was carried out with the objective of ascertaining the effects of the burning rate index on the average pressure and the total burning time of the pressure time profiles. A constant ‘H’ is introduced to obtain close-form expressions for the initial pressure, the maximum pressure, the area under the pressure time profile, the total burning time and the average pressure. The derivation of the total burning time for a progressive burning tubular rocket propellant is a new approach described in this paper. It is observed that the average pressure during propellant combustion varies with the burning rate index. A higher burning rate index of the propellant leads to a lower average pressure for lower burning rate propellants (8 mm/s at 7 MPa) and a higher average pressure for higher burning rate propellants (10 mm/s at 7 MPa). A unique situation occurs for an intermediate burning rate propellant (9 mm/s at 7 MPa), where the maximum pressure was obtained theoretically for a specific value of the burning rate index (0.69).

Opis:

Progressive supranuclear palsy [Steele-Richardson-Olszewski] is a neurodegenerative disease of the central nervous system. It develops mainly in men over 40 years of age. The course of PSP is rather characteristic: motor, cognitive and non-cognitive impairments develop at a fairly rapid rate. The aim of the study is to assess interactional, communicative and linguistic competencies and skills, executive abilities (breathing, phonation and articulation) as well as primary functions of a patient diagnosed with PSP. The article confirms the thesis that dementia disorders overlap with motor disorders in the course of PSP.

Opis:

The primary progressive aphasia (PPA) or Mesulam syndrome is an isolated and progressive deterioration of language, usually due to progressive focal atrophy of the left peri sylvian regions. Given that very little data on PPA is available in non-Western languages in the literature, we describe the first case of logopenic PPA in Arabic. Neuropsychological, neuroimaging and linguistic protocol have been administered to the patient. The Neurolinguistic assessment was carried out with the Moroccan version of the Montreal-Toulouse linguistic exploration protocol, the apraxia of speech protocol, the Moroccan version of MLSE (Mini-Linguistic Status Examination); some subtests of the BDAE (Boston Diagnostic Aphasia Examination) while the computerized acoustic analysis was performed with Vocalab4 ™. The acoustic analysis showed mainly instability in pitch and amplitude. However articulatory disruptions are very mild in our case. There is a parallelism between spoken language which is marked by phonological paraphasias with a „pseudostuttering „and written language disorder which displays a phonological alexia, a severe acalculia and an agraphia. Our pa tient presents L-PPA subtype 1 on the logopenic spectrum. These results are consistent with the neuropsychological hypothesis of a dysfunction in phonological buffer reflecting the features of logopenic PPA. Furthermore, our case displayed atypical neurolinguistic patterns in comparison with other cases described in the European languages due to the Arabic specific linguistic structure.

Opis:

The aim of the article is to present the subjective perspective of a person with congenital low vision who experienced gradual vision deterioration up to total loss. The case study method was used, in which the narrative biographic interview was the main technique of collecting data. In the analysed narratives, certain milestones were identified in the process of coping with the consequences of progressive impairment. Those were the situations when the subject was no longer able to perform a specific task, which she had earlier performed under visual control. They made the subject realise the progressive nature of the disease and inevitably confronted her with the acquisition of permanent severe impairment. Those situations caused temporary disruption of her psychological balance and increased her demand for emotional support. With time, however, they also motivated the subject to use previously rejected rehabilitation devices and techniques. Lack of knowledge of functional implications of eye conditions (including reduced acuity and contrast sensitivity, field defects, light/dark adaptation problems, etc.) among family members and other people hindered the process of providing optimal instrumental support to the subject.

The paper presents a review of the suspension solutions used on the street vehicle up to the now a days, finalising with presentation of their damping characteristics and with evaluation of their advantages or disadvantages. Long time the suspension systems have been dominated by the classic passive suspensions realized with metallic springs, shock absorbers with constant damping coefficients and anti-roll bars, excepting some luxury and sport cars using semi-active and active suspensions. There are presented some semi-active suspension solutions with continuous or discontinuous damping characteristics adjustment and the evolution of the Citroen and other active suspensions. All of them improve in some matter the performances but all of them have not ability to recuperate energy and has auxiliary energy consumption so last period the electromagnetically shock absorbers are researched, the paper presenting some of them. The paper also presents magneto rheological MR damper, solutions for adjustable passive shock absorbers and solutions for passive shock absorbers with variable damping coefficient with the stroke, e.g. Monroe Sensa Trac, Citroën Solution and VZN solution, with their damping characteristics and performances.

The paper presents findings on secular score gains in Raven’s Progressive Matrices during six decades (1948- 2009) in Polish adolescents. Seven groups are being compared, comprising of 20, 490 subjects in total. The representative groups examined in 2000 (N=1,331) and 2009 (N=3,650) are those of special interest as they are the most numerous and allowing formal means comparison using standard test for comparison of means and Welch’s test. Possible causes for the noted effect are being discussed, with special emphasis on the economic growth and its implications - such as improved nutrition, education changes, growth of adolescent’s well-being and child upbringing practices.

Opis:

In this essay, the author contends that the approach to education described by Rousseau in Émile is not only impractical but is founded on four misconceptions concerning human nature and development. These are (1) the vulnerable-child child fallacy (that children must be protected from learning the wrong things); (2) the stage-of-development fallacy (that children can learn only certain kinds of things at certain ages); (3) the lone-child-in-nature fallacy (that children learn best from interacting physically with nature, not from interacting verbally with other people); and (4) the controllability fallacy (that is is possible to know a child so well as to be able to control, through subtle means, what the child learns). The author’s own research indicates that the ideal environment for children’s natural, self-directed learning is very different from, in many ways opposite to, that outlined by Rousseau.

Opis:

Currently the CEN/TC250 is completing the development of a new (second) generation of Structural Eurocodes. The checking of robustness remains one of the important stages in the design of structural systems. Recommended design strategies for robustness checking are based on provisions given in actual EN 1991-1-7. A Non-linear pseudo-static analysis is widely used by following reasons: a non-linear structural analysis based on more realistic constitutive relations for basic variables makes possible a simulation of the real structural behaviour. Implementation of the non-linear pseudo-static analysis for assessment of the structural system in accidental design situation requires an alternate approach to safety format. The paper presents an innovative approach to safety format calibration for non-linear analysis of RC-structures subjected to accidental loads.

Opis:

Performing social roles, including family-related ones, by people with visual impairment is associated with experiencing various types of difficulties It is basically a consequence of the socially established negative image of these people who areperceived as not fully competent and requiring assistance. Previous few studies devoted to the motherhood of blind and partially sighted women indicate relatively frequent reactions of their social environment expressing the belief that a visually impaired woman is not able to perform her role as a wife and mother in a proper way. The psychosocial situation of fathers with visual impairment is rarely analysed in research activities, and knowledge of the relationship between gradual loss of vision and experience of fatherhood is relatively poor. The aim of the article is to present the results of a qualitative study focused on learning the subjective experience of performing the role of a parent by a man with progressive vision loss. In the biographical study of an individual case, the narrative interview technique was used, and the analysis of the collected material was referred to such spheres of experiencing fatherhood as: the concept of role, sources of satisfaction and positive experience related to the role, perceived relationships between the way of performing the role and progressive impairment.

The below article has as its purpose presentation to a Polish reader of the criticism of christology of American Protestant fundamentalist circles by a bishop of the Episcopal Church in the USA and a Protestant theologian John Shelby Spong (born in 1931) and then explanation of his own understanding of christology. Protestant fundamentalists in the USA share five core beliefs, considering them as basic and irrefutable Christian dogmas: (1) the inerrancy of the Bible, (2) the virgin birth and divinity of Jesus Christ, (3) the substitutionary atonement of Christ on the cross, (4) the bodily resurrection of Jesus Christ and (5) His return and the Last Judgment. In his works published between 1973 and 2007, John Shelby Spong refutes those beliefs, using theological (biblical) and philosophical (reason) arguments and the method of Haggadic midrash used to interpret the four Gospels.
Niniejszy artykuł ma na celu przedstawienie polskiemu czytelnikowi krytyki chrystologii amerykańskich protestanckich środowisk fundamentalistycznych biskupa Episkopalnego Kościoła USA i protestanckiego teologa Johna Shelby’ego Sponga (ur. 1931 r.) oraz zaprezentowanie jego własnego ujęcia chrystologii. Fundamentaliści protestanccy w USA podzielają pięć wierzeń uznając je za podstawowe i niepodważalne dogmaty chrześcijaństwa, które należy rozumieć w sposób dosłowny: (1) werbalną bezbłędność Pisma Świętego, (2) dziewicze narodzenie i bóstwo Jezusa Chrystusa, (3) zastępczą ekspiacje Jezusa na krzyżu, (4) cielesne zmartwychwstanie Jezusa Chrystusa oraz (5) powtórne Jego przyjście i Sąd Ostateczny. W swoich pracach opublikowanych na przestrzeni lat 1973-2007 John Shelby Spong dogmaty te podważa odwołując się do argumentów natury teologicznej (biblistycznej) i filozoficznej (ludzkiego rozumu) oraz metody hagadyjskiego midraszu zastosowanego do interpretacji czterech Ewangelii.

The plywood is considered as a layered cross-ply unidirectional fibre reinforced composite. The experimental Compact Tension (CT) tests carried out in different directions of plywood fibre orientation show that the characteristics of damages are fibre bundle rupture, matrix cracking along the fibres, and delamination at the ply interlayers of glue. The plywood CT specimens are modelled by continuum shell and cohesive finite elements with damage evolution in material models. The Finite Element (FE) model simulates the experimental behaviour of plywood samples very well and allows deep investigation of the different types of damage development and interaction. The FE model of plywood is useful for its lay-up optimization and for development of very efficient in large-scale simulations computational models of plywood.

The essay is devoted to the relationship between the design of school furniture and other interior design elements in the open-air school (école de plain air) in Suresnes (designed by E. Beaudoin and M. Lods, 1932–1935) and the pedagogical and social assumptions accompanying its construction. The functioning of the school and the role that furniture plays in this program are discussed, as well as how the furniture design responded to the interesting pedagogical program of the international outdoor school movement. The second part of the text discusses the main trends in the design of school furniture in France in the interwar period. Architects’ theoretical views on the problem of so-called “new education” in the design of school buildings and their equipment (mainly texts and projects by Maurice Barret, published in “Architectured’aujourd’hui”). Trends in furniture design are presented against the background of the pedagogical concepts of that era: Maria Montessori’s pedagogy and progressive trends in teaching, under the influence of which class spaces began to be designed as rooms with flexible functions, thanks to features such as light, multi-functional school furniture using modern shapes and materials.

Here, we have developed a highly sensitive, real-time allelic discrimination assay enabling detection of the Y831C mutation in the POLG1 gene. The Y831C mutation is present in the Polish population at a frequency of 2.25%. The new assay is well suited to both extensive population studies and molecular diagnostics of POLG1.

Opis:

Homocysteine is an indirect metabolite of methionine metabolism, as well as of creatinine, and it plays an important role in many biochemical processes. Physical effort modifies homocysteine concentration in the blood, as well as the substances taking part in its metabolism. The aim of the study was to assess the influence of intensive efforts of diverse energy changes on the concentrations of homocysteine and the vitamins involved in its metabolism – vit. B6, vit. B12 and folic acid. In the study athletes performed Wingate and progressive test. Before and after tests homocysteine, vitamins B6, B12 and folic acid and creatinine were assayed. Concentration of homocysteine, vit. B12 and creatinine in the blood increased after both tests. Concentration of vit. B6 decreased and folic acid increased after Wingate test while they did not change after a progressive test. Homocysteine concentration negatively correlated with folic acid but positively with creatinine concentration in the blood, as well as with LBM. Regardless of its duration and energetic changes, intensive effort leads to an increase in homocysteine concentration. Correlation of homocysteine with creatinine and the LBM suggest that people with bigger muscle mass can have higher homocysteine concentration in the blood.

Introduction. High prevalence of elevated serum pancreatic enzymes in children with cholestasis with normal fecal elastase-1 concentrations has been documented. However, this state is related predominantly to biliary atresia. Therefore, we aimed to assess pancreatic damage by measuring serum pancreatic enzymes in patients with progressive familial intrahepatic cholestasis type 2 (PFIC type 2). Materials and methods. Twenty PFIC type 2 patients with normal serum bilirubin and bile acid concentrations were included in the study. Thirty pancreatic insufficient cystic fibrosis (PI-CF) patients, thirty patients with acute pancreatitis (AP) and thirty healthy subjects (HS) served for the purpose of comparison. In all subjects, serum lipase and elastase-1 levels were measured. Results. In all but one PFIC type 2 patients and all HS normal lipase activities were found. Serum elastase-1 concentrations were normal in all PFIC type 2 patients and HS. The enzyme levels were very similar in both groups studied. Lipase activities in PFIC type 2 patients were significantly higher than in PI-CF patients (p < 0.00001) and lower than in patients with AP (p < 0.00001). Serum elastase-1 levels in PFIC type 2 patients were significantly lower than in patients with AP (p < 0.00001) and not different from those in PI-CF patients. In conclusion. serum pancreatic enzymes in patients with PFIC type 2 are normal. No pancreatic damage in these patients could be detected.

Opis:

The external loads and structural ultimate strength are two important aspects for the safety of ship hull girder. It may collapse in case the structural capacity is less than the external forces in extreme seas. In the present research, progressive collapse test is performed to investigate the collapse mechanism of ship structure in waves. External load with time history and corresponding structural collapse behavior are measured and discussed to demonstrate the interaction of fluid and structures.
