Opis:
The objective of this paper is to demonstrate the use of elements of sustainable design in public buildings in the context of contemporary architectural design solutions and zero-energy standards for newly designed buildings in California, USA. The paper presents a detailed overview of the main task of the "Architecture at Zero 2020" international architectural competition, organised by the American Institute of Architects California – a design of the San Benito County Public Library in Hollister, CA. The paper also features a detailed analysis of the competition's outcome, with a specific focus on Andrzej Kaczmarek's design, which was given the merit award in the competition’s student projects category. The competition resulted in the presentation of the library's design alternatives, each suited to contextspecific environmental and climate determinants and optimised in terms of energy. Andrzej Kaczmarek's design met these requirements, as demonstrated via calculations performed using eQuest 3–64 software. The design was recognised not only because of its optimised energy balance, but also the excellence with which it satisfied the needs of local citizens and how it reflected a thorough understanding of the site's placebased character. The library was successfully blended in with its historical context via its simple form that was partially embedded underground. The building was designed to feature an array of advanced engineering solutions intended to secure it against earthquakes and optimise its heat balance, including kinetic façades and retractable glazed roof elements, photovoltaic panels, wind turbines and Pavegen floor surfaces.
Celem artykułu było ukazanie sposobów wykorzystania elementów projektowania zrównoważonego we współczesnych budynkach użyteczności publicznej, w kontekście architektonicznych rozwiązań projektowych i standardów zeroenergetycznych przewidzianych dla nowo projektowanych budynków w Kalifornii. Przedmiotem szczegółowych prac był projekt biblioteki publicznej hrabstwa San Benito w Hollister w Kalifornii, stanowiący zadanie w międzynarodowym konkursie architektonicznym „Architecture at Zero 2020”, organizowanym przez American Institute of Architect California. W artykule przeanalizowano wyniki tego konkursu, a w szczególności projekt autorstwa Andrzeja Kaczmarka, który zdobył równorzędną nagrodę w kategorii prac studenckich. Efektem konkursu było uzyskanie alternatywnych rozwiązań biblioteki dopasowanych do uwarunkowań środowiska naturalnego i klimatu, a przede wszystkim zoptymalizowanych pod względem energetycznym. Projekt Andrzeja Kaczmarka spełnił jego wymagania, co wykazano, przeprowadzając obliczenia za pomocą programu eQuest 364. Projekt ten został nagrodzony nie tylko za zoptymalizowanie bilansu energetycznego, ale również za znakomite spełnienie potrzeb mieszkańców i zrozumienie charakteru miejsca. Dobre wkomponowanie biblioteki w historyczne otoczenie uzyskano, nadając budynkowi prostą formę̨ i zagłębiając go częściowo pod ziemię. W obiekcie zastosowano wiele zaawansowanych rozwiązań technicznych mających na celu zabezpieczenie budowli przed trzęsieniami ziemi i prowadzących do optymalizacji bilansu ciepła, w tym: kinetyczne fasady i ruchome oszklone dachy, panele fotowoltaiczne, turbiny wiatrowe i posadzki typu Pavegen.

Opis:
This article has originated from observations of the current Polish political and legal disputes over the Constitution. In pursuing the reasons for the different lines of the argumentation presented, we have brought the issue of education in constitutional law to attention. We have covered the issue in two stages. The first stage involves a discussion of education models as expounded in social theory. Our starting point was the structural-functional model and its criticism along the lines of conflict, interpretative, and critical theories. This is followed by a presentation of the evolution of administrative-law institutions in the light of the conflict between the expected openness to ethical and political dimensions and the claims for integrity and coherence. To this end, we followed the proposals of Nonet and Selznick. The second stage includes a review of three conceptions of the constitution and constitutionalism. The views of Kelsen, Schmitt as well as the American judicial review doctrine served as model examples. These proposals can be presented as the cornerstones of three visions of constitutional-law education. We did not content ourselves with presenting a set of models of education and covering a reconstruction of the vision of constitutional education. We have also attempted to demonstrate, bearing in mind the nature of the Polish debate over the Constitution, that the judicial review doctrine opens up a promising sphere for a revaluation of both the theory and practice of constitutional law.

Opis:
The nonparametric Mann-Whitney test [Mann-Whitneу (1947)] is one of commonly used two sample tests. The problem of tied ranks exists in the case of discrete distributions. It makes the analysis of distribution of Mann-Whitney test quite complicated. There is continuing interest in the properties of this test's statistics. It can be seen from many of papers concerning the distribution of this statistic according to the assumption of equality of distributions about the critical values tables and test s power. In this paper we shall present an approximation of Mann-Whitney statistics, critical values, compared with the most often used approximation by normal distribution. We will determine the unconditional distribution of U-statistics for P=1/2 in the case of tied ranks. We will compare the interpolated quantiles of these distributions with the case of continuous distribution without the tied ranks.

Opis:
Cervical cancer is the second, after breast cancer, most frequent malignancy in the females worldwide. Annually, about 500 000 new cases are diagnosed and about 275 000 women die thereof. Most cases of cervical cancer are epithelial in origin, while only 15-35% are adenomatous. Recent epidemiological data indicate a gradually increasing incidence of adenocarcinoma with concomitant reduction planoepithelial cancer. The paper presents a case of a 50-year-old patient diagnosed with a cervical adenocarcinoma with bilateral adnexal metastases and concomitant ascites. Clinical signs and intraoperative findings initially suggested an ovarian cancer at FIGO stage IIIC. Based on histological studies, the final diagnosis of adenocarcinoma with adnexal metastases was made. Tumor metastases from the genitals usually originate from ovarian or endometrial cancer. Metastases from the cervical cancer are much less frequent. There are few publications dealing with this issue in the world literature. Furthermore, available papers provide widely divergent data concerning the incidence of metastases to the ovaries and oviducts. Some authors highlight the necessity to exclude the reverse situation – metastases of ovarian cancer to the uterine cervix. Such data only confirm complexity of this issue. Therefore we decided to present the following case report.
Rak szyjki macicy to drugi co do częstości, po raku sutka, nowotwór występujący u kobiet na całym świecie. Obserwujemy około 500 000 zachorowań rocznie, w tym 275 000 zgonów rocznie z powodu tej choroby. Nowotwory nabłonkowe stanowią większość raków szyjki macicy. Jedynie 15-35% nowotworów szyjki to rak gruczołowy. Ostatnie dane epidemiologiczne wskazują na stopniowy wzrost zachorowalności na raka gruczołowego przy jednoczesnym spadku zachorowań na raka płaskonabłonkowego szyjki macicy. W pracy przedstawiono przypadek 50-letniej pacjentki, u której zdiagnozowano raka gruczołowego szyjki macicy z przerzutami do obu jajników i jajowodu oraz towarzyszącym wodobrzuszem. Obraz kliniczny i śródoperacyjny sugerował początkowo raka jajnika w stopniu zaawansowania IIIC wg FIGO. Po uzyskaniu wyniku badania histopatologicznego postawiono diagnozę raka gruczołowego z przerzutami do przydatków. Przerzuty nowotworowe z narządu płciowego występują najczęściej z raków jajnika lub trzonu macicy. Przerzuty z raka szyjki są spotykane zdecydowanie rzadziej. W piśmiennictwie światowym jest niewiele doniesień na ten temat. Ponadto w dostępnych pracach autorzy podają różne dane liczbowe co do częstości występowania przerzutów do jajników i jajowodów. W niektórych pracach wskazuje się na fakt, że istnieje konieczność wykluczenia odwrotnej sytuacji – przerzutów raka jajnika do szyjki macicy. Dane te świadczą o złożoności zagadnienia – był to powód, dla którego postanowiliśmy opisać przypadek naszej pacjentki.

Opis:
Background: Hearing loss caused by excessive exposure to noise is one of the most common health risks for employees. One solution for noise reduction is the use of hearing protectors, which is a very effective method for protecting hearing from the workplace noise. In order to obtain better attenuation efficiency, custom moulded earplugs can be equipped with a suitable acoustic filter. The effectiveness of the hearing protectors’ attenuation is based on real measurement of hearing thresholds for normal hearing people with and without hearing protectors. However, this is a time consuming process, and the obtained values are characterised by quite large inter-individual variability. The optimal solution is to measure the attenuation characteristics based on the objective method (without the presence of the subject), the results of which will be in accordance with the results of subjective tests. Therefore, the main purpose of the research in this work was to measure the attenuation characteristics of the self-designed custom moulded earplugs with and without acoustic filters through the use of subjective and objective methods, and to compare the results in terms of the research methods. Methods: Measurements of the acoustic attenuation obtained by custom moulded earplugs with designed F1, F2, and F3 acoustic filters (internal diameters dF1 = 1:25 mm, dF2 = 0:85 mm, and dF3 = 0:45 mm), as well as full insert earplugs (without any acoustic filters) were carried out using two methods: objective and subjective. The objective measurements were carried out in an anechoic chamber. The artificial head (High-frequency Head and Torso Simulator Brüel & Kjær Type 5128) was located at a distance of 3 m, directly opposite the loudspeaker. The test signal in the measurements was pink noise – in the frequency range up to 12.5 kHz and the level 85, 90, and 95 dB. The hearing protectors with and without acoustic filters were mounted in the Head and Torso Simulator which was connected with Pulse System Brüel & Kjær. Five normal hearing subjects participated in the subjective measurements. A pink noise signal was used for one-third octave bands: 125, 250, 500, 1000, 2000, 4000, and 8000 Hz. The attenuation value was defined as the difference (in dB) between the hearing threshold of the test signal with a hearing protector and the hearing threshold determined without a hearing protector. Results: The results of the objective method proved that in addition to the significant impact of frequency on the attenuation values, the type of filter used in custom moulded earplugs also had a significant effect. In addition, the results of the objective method showed that in the whole frequency range the highest attenuation values are shown by the full earplugs, achieving slightly above 45 dB for frequency of 8 kHz. The attenuation values obtained from subjective measurements also confirmed that both the frequency and type of filter significantly affect the attenuation values of the tested hearing protectors. Conclusions: The results of this study did not confirm the hypothesis that the measurement method had no significant effect on the attenuation characteristics of self-designed custom moulded earplugs with different types of acoustic filters. The largest differences in attenuation values between the type of measurement methods occur for the low frequency band (250 Hz) and for higher frequencies (4000 Hz mainly). The change of the internal diameter of the F1 filter from 1.25 mm to 0.85 mm (F2 filter) did not significantly affect the attenuation characteristics.

Opis:
Research background: The nature of bankruptcy has been the subject of interest for economic theories, both positive-identifying relationships between bankruptcy and other economic categories - and normative, shaping the rules for the proper regulation of bankruptcy. In turn, the functioning of an enterprise in conditions of risk, financial threat, and finally a crisis that could lead to bankruptcy, are of interest to management. The interpenetration of these two dimensions provided the motivation for this study, which assumes a bottom-up approach: from individual results to summarised multi-sectional comparisons. Purpose of the article: The purpose of the research was to evaluate the level, directions of change, and structure of the degree of financial threat in industrial enterprises. The period under analysis was 2007-2018 and the whole population of industrial enterprises in Poland (15,999 entities) was examined. The enterprises were small and medium-sized enterprises (SMEs) as well as large enterprises (LEs). The financial analysis covered macro-, meso-, and microeconomic levels. Methods: The analysis was conducted using a comparative approach and financial threat predictions obtained from the original multivariable logit model. Heat maps were used to evaluate the intensity of changes in financial threat. The displacement of objects in structures was studied, ordered, and classified. Four normative standards of threat scenarios were defined and then used to evaluate similarities in the profiles of the structures examined, using the similarity measure. The ranking and its variability were analysed in the assessment of profiles. Findings & value added: As the result of the research, properties were described and profiles were determined for the structures in terms of the degree of threat and its correlation with rate of bankruptcy and creating added value. The originality of the research comes from the use of novel dynamic logit models. The added value is a unique study on the entire population of industrial enterprises in the national economy and a methodology for identifying financial threat profiles and their similarity at subsequent aggregation levels (the micro-, meso-, and macro-levels). This made it possible to derive patterns and regularities for economic policy and guidelines for business management.

Opis:
Adenosine 5'-phosphoramidate (NH2-pA) is a rare natural nucleotide and its biochemistry and biological functions are poorly recognized. All organisms have proteins that may be involved in the catabolism of NH2-pA. They are members of the HIT protein family and catalyze hydrolytic splitting of NH2-pA to 5'-AMP and ammonia. At least five HIT proteins have been identified in mammals; however, the enzymatic and molecular properties of only Fhit and Hint1 have been comprehensively studied. Our study focuses on the Hint2 protein purified by a simple procedure to homogeneity from sheep liver mitochondrial fraction (OaHint2). Hint1 protein was also prepared from sheep liver (OaHint1) and the molecular and kinetic properties of the two proteins compared. Both function as homodimers and behave as nucleoside 5'-phosphoramidate hydrolases. The molecular mass of the OaHint2 monomer is 16 kDa and that of the OaHint1 monomer 14.9 kDa. Among potential substrates studied, NH2-pA appeared to be the best; the Km and kcat values estimated for this compound are 6.6 μM and 68.3 s-1, and 1.5 μM and 11.0 s-1 per natively functioning dimer of OaHint2 and OaHint1, respectively. Studies of the rates of hydrolysis of different NH2-pA derivatives show that Hint2 is more specific towards compounds with a P-N bond than Hint1. The thermostability of these two proteins is also compared.

Opis:
In the reliability analysis of a sealing structure, radial clearance of the contact surface is usually regarded as a failure criterion, and the sample size is usually quite small, which brings great challenges to uncertainty quantification. Therefore, this paper proposes a reliability analysis method based on the leakage mechanism of the sealing. With the application of dynamic interval, the proposed method can be used to deal with problem of degradation in small sample to evaluate reliability. Moreover, the dynamic reliability with the mixture of the probabilistic and non-probabilistic variables can be obtained using the proposed method. An illustrative numerical case study of a spool valve is conducted in order to validate the proposed method and the implemented reliability sensitivity analysis. The proposed method is of great help in evaluating and predicting reliability with small degradation sample and hybrid uncertainties.

Opis:
The article focuses on the results of a study on the relationship between working memory and emotion regulation. The relationship between working memory and emotion regulation is expected to manifest itself especially in situations of applying emotion regulation strategies that engage cognitive resources, such as cognitive reappraisal and positive reappraisal. We assumed that, compared to participants low in working memory capacity, participants high in working memory capacity would report using the above strategies more frequently. In our study (N = 65), the participants completed two questionnaires: the Emotion Regulation Questionnaire and the Cognitive Emotion Regulation Questionnaire, as well as a well-validated measure of working memory capacity known as the Operation Span Task. Our hypotheses were confirmed. The results were interpreted in relation to such constructs as temporal organization of emotion regulation strategies, affective flexibility, or forms of reappraisal.

Opis:
Expression of p16 protein, intragenic mutations of CDKN2A and hypermethylation of CDKN2A promoter region in 41 sporadic primary uveal melanomas were studied. There were 2 cases of spindle cell B histological type, 11 of A + B and 28 of mixed type. All melanomas infiltrated sclera but in 28 cases infiltration was superficial while in 13 profound. In 7 cases the tumor infiltrated the optic nerve. Expression of p16 was studied by immunohistochemistry and recorded by assessment of the proportion of positive tumor cells and staining intensity. Results were expressed as staining index (IRS). Intragenic mutations were studied by PCR-SSCP followed by sequencing, while hypermethylation of the promoter region by CpG methylation assay. In 15% of cases less than 10% of melanoma cells were p16 positive, in 70% of cases less than 50% of cells, while in 7% more than 80% of cells stained for p16 (mean IRS for all cases was 4.87 ± 2.43). In B type the IRS was 8.5 ± 0.7, in A + B type 6.0 ± 2.1 and in the mixed type 4.17 ± 2.43 (differences statistically significant). In melanomas profoundly infiltrating sclera mean IRS was 4.16, while in those infiltrating optic nerve 3.71 (statistically not significant). Analysis of the intragenic mutations revealed in two patients a GAC/GAT substitution in codon 84 - a silent mutation. No hypermethylation of the CpG island of the p16 promoter region was found.
