Opis:
Models describe our beliefs about how the world functions. In mathematical modelling, we translate those beliefs into the language of mathematics. Mathematical models can yield prognose on the base of applied fertiliser dose. In this work results of finding yield mathematical model according to fertiliser (nitrogen) dose for perennials (willowleaf sunflower Helianthus salicifolious, cup plant Silphium perfoliatum and Jerusalem artichoke Helianthus tuberosus) on marginal land are presented. Models were described as normalised square equations for dependence between yield and fertiliser doses. Experiments were conducted in lisymeters and vases for willowleaf sunflower and cup plant. For Jerusalem artichoke experiments were done in vases only. All experiments have been doing during two years (2018 and 2019) for different fertilisers doses (45, 90 and 135 kg N∙ha-1) in three repetitions. From simulations maximal yield could be achieved for following fertiliser doses – willowleaf sunflower 104 kg N∙ha-1, cup plant 85 kg N∙ha-1 and Jerusalem artichoke 126 kg N∙ha-1.

Opis:
Dissemination of algorithms for decision-making aiding in the design of furniture and other products made of lignocellulosic materials in the scientific literature. The issue of the proper selection of dimensions of the designed products can be supported with the use of mathematical algorithms built into CAD systems. There are many such algorithms, they have their specificity and areas of application. The article lists a dozen or so of the most popular algorithms of this type, and then checks their prevalence in the scientific literature on furniture design. The result is a point the method (group of methods) that best takes into account the specific features of lignocellulosic materials. The main conclusion is that the most popular algorithms are: the ε-constraint method, genetic algorithms and artificial immune systems. The most popular is the ε-constraint method.
Upowszechnienie w literaturze naukowej algorytmów wspomagających podejmowanie decyzji w projektowaniu mebli i innych wyrobów z materiałów lignocelulozowych. Zagadnienie właściwego doboru wymiarów projektowanych wyrobów może być wspomagane za pomocą algorytmów matematycznych wbudowanych w systemy CAD. Takich algorytmów jest wiele, mają one swoją specyfikę i obszary zastosowań. W artykule wymieniono kilkanaście najpopularniejszych algorytmów tego typu, a następnie sprawdzono ich rozpowszechnienie w literaturze naukowej dotyczącej projektowania mebli. Wynikiem jest metoda punktowa (grupa metod), która najlepiej uwzględnia specyficzne cechy materiałów lignocelulozowych. Główny wniosek jest taki, że najpopularniejsze algorytmy to: metoda ε-ograniczenia, algorytmy genetyczne i sztuczne układy odpornościowe. Najpopularniejsza jest metoda z ograniczeniem.

Opis:
Numerous human transcripts contain tandem repeats of trinucleotide motifs, the function of which remains unknown. In this study we used the available gene expression EST data to characterize the abundance of a large group of these transcripts in different tissues and determine the mRNAs which had the highest contribution to the observed levels of transcripts containing different types of the CNG repeats. A more extensive characteristics was performed for transcripts containing the CUG repeats, and those encoding the repeat-binding proteins. The scarcity of double-stranded CUG repeats as well as various proportions of the single-stranded and double-stranded CUG repeat-binding proteins were revealed in the studied transcriptomes. The observed correlated levels of transcripts containing single-stranded CUG repeats and of proteins binding single-stranded CUG repeats may imply that in addition to transcripts which only provide binding sites for these proteins there may be a substantial portion of the transcripts whose metabolism is directly regulated by such proteins. Our results showing a highly variable composition of triplet repeat-containing transcripts and their interacting proteins in different tissues may contribute to a better understanding of the mechanism of RNA-mediated pathogenesis in triplet repeat expansion diseases.

Opis:
On the 1st of. May 2015, in Meatpacking District of West Manhattan, the new building of the Whitney Museum of American Art was opened. It is the fourth location of this well-known New York museum, which was established in 1930, by Gertrude Vanderbilt Whitney. The Whitney possesses the world’s largest collection of American art and focuses on exhibiting living artists. Spectacular, industrial in character architecture signed by Renzo Piano has met with mixed reactions. The building is functional and well connected with the post-industrial site, however, not appreciated by everyone. Similar situation happened forty years ago, when Centre of Georges Pompidou, designed by Renzo Piano and Richard Rogers, pioneers of high-tech architecture, was widely criticised. Only popularity, high attendance and commercial success of famous Paris facility changed that negative opinion. Is the New Whitney following the same path – time will tell.
1 maja 2015 r., w zaułku zachodniego Manhattanu zwanym Meatpacking, otwarta została nowa siedziba Whitney Museum of American Art. Jest to już czwarta lokalizacja tego znanego nowojorskiego muzeum, założonego w 1930 r. przez rzeźbiarkę Gertrude Vanderbilt Whitney. Muzeum posiada największą na świecie kolekcję amerykańskiej sztuki współczesnej. Jego działalność koncentruje się na promocji twórczości artystów żyjących. Oryginalna, industrialna w wyrazie architektura, autorstwa pracowni Renzo Piano, wzbudziła mieszane uczucia. Pomimo, że budynek jest funkcjonalny i znakomicie powiązany z miejscowym poprzemysłowym kontekstem, nie wszystkim przypadł do gustu. Podobna sytuacja miała już miejsce 40 lat temu w Paryżu, kiedy krytykowano nowatorskie Centrum Pompidou, wspólne dzieło architektów Renzo Piano i Richarda Rogersa, pionierów stylu współczesnej architektury nazwanego high-tech. Dopiero wielka popularność i sukces frekwencyjny słynnej paryskiej „rafinerii” spowodował zmianę ocen tego obiektu. Czy tak się też stanie w wypadku nowej siedziby Muzeum Whitney w Nowym Jorku – czas pokaże.

The aim of this study was to overproduce, identify and apply novel laccase-like multicopper oxidases (LMCOs) from Myrothecium roridum in a dye removal process. LMCOs' production was enhanced by modifying the medium and adding copper ions. After purification, two proteins, LMCO1 and LMCO2, with molecular masses of 46.7 and 66.3 kDa were discovered. Peptide analysis by mass spectrometry revealed that they belong to the cupredoxin superfamily. Characteristic peptide sequences were obtained for MCOs and bilirubin oxidases. Crude enzymes were applied in a dye decolorization process. Supplementation with 1 mM of vanillin allowed an almost complete elimination of the Indigo carmine within 3 hours. The dye was removed from a solution containing metals, surfactants and organic solvents. The in-gel assessment of the activity and decolorization ability of MCOs, followed by protein extraction and SDS-PAGE, confirmed that only LMCO2 was responsible for the dye removal. MCOs produced by Myrothecium sp. have been poorly studied before. The obtained results broaden knowledge on this subject and may contribute to the development of an eco-friendly method of dye elimination.

Opis:
Opened in January 2019, the Museum Susch crowned the collecting efforts of Grażyna Kulczyk, who, following her failed attempts at establishing a contemporary art Museum in Poznan and Warsaw, finally found home for her collection in a small Swiss village located between two Alps resorts: Sankt Moritz and Davos. The combination of both spectacular mountainous landscape and the edifices of an old convent into which the display has been built, as well as the purposefully created art pieces, contribute to creating a peculiar atmosphere of the place. Nature, architecture, and art have all merged into one total work here, namely into a contemporary Gesamtkunstwerk. Poland is echoed in the Museum: e.g. the genuine name of the institution: ‘Muzeum Susch’ is a combination of Polish and German words; furthermore, the pieces presented in the collection are to a great extent made up of works by contemporary Polish artists; wooden walls of the Museum Café are decorated with prints showing the Zakopane ‘Under Fir Trees’ (Pod Jedlami) Villa. The question whether Grażyna Kulczyk’s collection has found its final home here, or whether it is still possible for it to return to Poland, continues open. The collector herself does not provide an unambiguous answer to this.

The objective of this study is to analyse the issue of the long-term unemployment and the ways it changes on the Polish labour market. The research problem is based on the answer to the question if the issue of long-term unemployment is equally severe for all regions of Poland. The research results will answer the question whether the issue of long-term unemployment is a problem of the whole country or only some of its regions and, therefore, what kind of action – at central or regional level – should be primarily used to deal with this phenomenon. The data used in the analysis come from GUS (Central Statistical Offie), that is the Polish institution gathering statistical data.
Celem opracowania jest analiza bezrobocia długotrwałego oraz sposobu jego zmian na polskim rynku pracy. Problem badawczy opiera się na odpowiedzi na pytanie, czy sprawa bezrobocia długookresowego jest w równej mierze dotkliwa dla wszystkich regionów Polski. Wyniki badań pozwolą odpowiedzieć na pytanie, czy problem długotrwałego bezrobocia jest problemem całego kraju czy tylko niektórych jego regionów, a zatem jakie działania – na szczeblu centralnym lub regionalnym – powinny być przede wszystkim wykorzystywane do radzenia sobie z bezrobociem długotrwałym. Dane zaczerpnięte do badań pochodzą z GUS-u, czyli instytucji państwa polskiego zajmującej się zbieraniem danych statystycznych.

Objectives The aim of the research was to explore the potential of the concept of work in the activity-based working (ABW) environment, including its impact on stress, back pain and psychomedical parameters of employees subjected to and not subject to relocation. Material and Methods The data of 396 employees of both sexes were analyzed. The study used standardized psychological questionnaires to measure the level of perceived stress (Perceived Stress Scale), the level of readiness for change (Readiness for Change Questionnaire), the severity of health behaviors (Health Behavior Inventory) and the level of general self-efficacy (General Self-Efficacy Scale). The set included questionnaires measuring the level of knowledge of occupational health and safety rules and the frequency of back pain. Results In the group of people whose workplace was moved to another building (in accordance with the concept), the relationship between the level of stress and selected variables: age, sense of generalized self-efficacy was checked. A significant negative correlation between the level of stress and age was confirmed (ρ = –0.16, p = 0.023), meaning a decrease in the level of stress with age. The level of stress correlated positively with the sense of efficacy (ρ = 0.21, p = 0.003), which means, the higher the sense of effectiveness, the higher the level of stress. In addition, it was confirmed that the level of stress in the group of people changing their location differed significantly from the general population. Conclusions Work in the ABW concept can contribute to the improvement of interpersonal communication and facilitate the social integration of employees and better evaluation of work in this model. Work in concept has not been shown to be a protective factor against back pain in people with obesity. It was confirmed that in people relocated from traditional office to office in the concept, relocation was associated with stress, but also with a greater sense of self-efficacy.

This chapter is focused on the application of association rules to classify medical data. There is no data mining technique that can produce consistent results for all types of medical data. The effectiveness of a data mining technique depends, among other things, on the type of data collected for study. The purpose of the following work is to see if combining two data mining methods will give better results than using them individually. For this purpose, data on breast cancer in women was used. The results showed that using a hybrid combination of association rules to produce a classifier can improve classification performance.

Abstract Vestibular voice includes participation of larynx structures which are absent in physiological process. Vestibular phonation may be desired when vocal folds are damaged as in paralytic dysphonia, or undesired in marginal hyperfunction. Vestibular voice may result from psychogenic dysphonia – phononeurosis. The aim of the study is perceptive evaluation of vestibular voice, objective larynx visualization, acoustic and aerodynamic examination. The study included 40 patients: 20 with vestibular voice, 20 with euphonic voice. Voice quality has been evaluated using perceptual GRBAS scale. Endoscopic and stroboscopic larynx examination used Endo-STROB-EL-Xion GmbH with visual tract. High-Speed Digital Imaging (HSDI) and High Speed (HS) camera registered true vocal folds vibrations. Acoustic evaluation of voice with DiagnoScope Specjalista, DiagNova Technologies included analysis of F0, Jitter, Shimmer, NHR, nonharmonic components. MPT has been analyzed. In examined group, hoarseness (95%), roughness (75%) and voice strain (55%) have been recorded. Endoscopy revealed edema of vestibular folds with dilation of vessels covering glottis. Stroboscopy and HSDI confirmed coexistence of hyperfunctional (95%) or paralytic (5%) dysphonia. Acoustic assessment revealed increase in Jitter, Shimmer, NHR and decrease in F0 and MPT. The vestibular voice is observed most frequently in women with hyperfunctional dysphonia (phononeuroses) or in paralytic dysphonia. Visualization techniques confirm the coexistence of vestibular folds hypertrophy and edema with vibration disorders. In the perceptual assessment, vestibular voice was hoarse, rough and strained. Acoustic examination showed increase of Jitter, Shimmer, NHR, presence of nonharmonic components and decrease of F0 and MPT.

Opis:
During pregnancy, voice quality disorders may occur in form of: edema, dryness, nervousness. The aim of the study is subjective and objective evaluation of voice quality in pregnant women. The study included 20 women in the third trimester of pregnancy, age of 20-31 diagnosed at the Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok. Subjective assessment has been based on the GRBAS scale. Objective assessment of the vocal organ used the HSDI technique (High Speed Digital Imaging). In the laryngeal visualization, high-speed camera (HS) using rigid endoscope with 90 ° optics has been used. Vibration of vocal folds has been recorded during phonation of vowel "e" at 4000 frames / sec. The glottal closure (GTs), symmetry, regularity and synchronization of vocal folds vibration have been assessed. In estimating the degree of glottal insufficiency, kymography of the larynx has been performed by analyzing the value of Open Quotient (OQ). Objective acoustic evaluation of voice has been also conducted using DiagnoScope Specjalista Program. Hoarseness has been observed in 15 pregnant women, whereas voice fatigability in 20 patients. Using HSDI, the edema of vocal folds in part of the group has been observed. Decreased MPT has been found in all examined women in the third trimester of pregnancy. Hoarseness and fatigability of voice are the most frequent subjective symptoms of voice organ in the third trimester of pregnancy. Decreased MPT is recorded objectively, as well as edema and insufficiency of vocal folds using HSDI technique.

Opis:
Psychogenic dysphonia is defined as disturbances in voice and speech quality with emotional background with lack of organic changes in the larynx. Mental condition has significant impact on the process of producing voice, functioning of respiratoryphonatory- articulation mechanism and speech prosody. The aim of the study was visual, acoustic, perceptual assessment as well as self-assessment of voice and speech quality using subjective and objective methods in patients with psychogenic dysphonia. The study included 50 patients with psychogenic dysphonia diagnosed in the Department of Clinical Fonoaudiology and Logopedics, Medical University of Białystok and treated at the Foniatric Outpatient Clinic, University Hospital in Białystok in 2017–2018. The control group consisted of 30 subjects with euphonic voice. All patients underwent subjective and objective assessment of voice and speech quality. The GRBAS scale, breathing pathway assessment, respiratory-phonatory-articulation analysis, voice and speech intensity evaluation have been performed. Speech prosody has also been examined. Patient selfassessment of voice has been conducted using Voice Handicap Index (VHI). Objective evaluation of larynx included vibrations of vocal folds visualization using High Speed Digital Imaging (HSDI). Acoustic analysis of voice quality has been performed using DiagNova Technologies. The maximum phonation time (MPT) has been determined. Hyperfunctional dysphonia is the most common clinical form of psychogenic dysphonia. Abnormal breathing pathway influence the reduction of MPT and disturbance of respiratory-phonatory-articulation coordination in patients with psychogenic dysphonia. In psychogenic dysphonia intonation and speech rate disorders are observed. Results of voice self-assessment in the majority of examined patients indicates a mild voice disability.
