New approach of model based detection of early stages of fuel injector failures
Authors: Mączak Jędrzej , Więcławski Krzysztof , Szczurowski Krzysztof
Published: February 2023

The aim of the work was to develop a method of real time diagnosing
electromagnetic fuel injectors using the observation of electric current
parameters available in the engine control unit. Performing this task
required finding a precise criterion for assessing the correct operation of
an electromagnetic injector. For this purpose, a mathematical model
describing the individual phases of the injector's operation was used,
allowing the simulation of the occurrence of typical failures. On its basis,
symptoms of particular failures were determined based on the
observation of electric current parameters in the control circuit.
Observation of voltage and current waveforms allows to locate both
electrical and mechanical damages to the injectors and to assess the
correctness of the power system components. The presented diagnostic
method allows the detection of the described damages in the early stages
of their development, which prevents damage to the catalytic converter
and other engine systems (valves, piston rings or cylinder surfaces), i.e.
damages resulting from an incorrect fuel mixture.

The 2019 coronavirus disease (Coronavirus disease 2019, COVID-19) poses a great threat to the health of people in all countries of the world. Infection with SARS-CoV-2 (Severe acute respiratory syndrome-related coronavirus 2) is a respiratory disease characterized by the development of severe life-threatening complications. COVID-19 is more likely to be severe and sometimes fatal, especially in older people with co-morbidities. A topical issue is predicting the course of chronic diseases in people who have contracted a coronavirus infection. An increasing number of cases of arthritis associated with COVID-19 have been reported in the literature, making this condition worthy of further study. It is known that the development of osteoarthritis is associated with oxidative stress and excessive production of reactive oxygen species. Lipid peroxidation products can serve as a marker of the intensity of free radical processes. The aim of the study was to determine the concentration of lipid peroxidation products in the synovial fluid of patients with osteoarthritis after SARS-CoV2 infection. All study participants were divided into two groups. The first group (n=22) is patients with osteoarthritis of knee joints II-III degree. The second group (n=14) is patients with osteoarthritis of the knee joints II-III degree, who suffered a mild and moderate form of COVID-19 6-9 months ago. In the conducted studies, the products of lipid peroxidation in the synovial fluid of patients of all research groups were evaluated.The content of diene conjugates was determined in the heptane-isopropanol extract by the spectrophotometric method, Schiff bases by the fluorimetric method. The content of TBA-active products was determined by the reaction with thiobarbituric acid (TBA). The processing of the research results was carried out using generally accepted methods of variational statistics. It was established that in the synovial fluid of patients with osteoarthritis of the knee joints who contracted COVID-19, the concentration of lipid peroxidation products increases compared to the group of patients with osteoarthritis (diene conjugates – by 1.7 times, TBА-active compounds – by 1,5 times, Schiff bases – 1.3 times). The detected changes indicate a violation of the oxidative-antioxidant balance. This indicates the prevalence of free radical processes and the development of oxidative stress directly in the joint. The results obtained by us indicate that patients with osteoarthritis may develop more severe joint damage and complications after infection with COVID-19.

Thyroid cancer is one of the few cancers diagnosed by cytological examination of thin nodule puncture biopsies. To achieve standardization of diagnostic terminology, morphological criteria and risk of malignancy in the whole world, the 6-level Bethesda system is used. The work aimed to analyze the results of cytological examination of fine-needle aspiration puncture biopsies (TAPBs) of thyroid nodules according to the international Bethesda system for the last three years and compare them with the world practice. As a result, 5687 surveys were conducted, where the proportion of women was 87.9% and of men 12.1%. Of all the cases, the most extensive cytological findings were of class II (benign formation) - 3061 studies (57%). The number of cases interpreted as class III was within the reference values, i.e. 8.2%. The fourth class accounted for 8.2%, the fifth for 3.5%, and the sixth for 5.0%. In total, these three classes account for 17.2%. Our analysis compared the reference values and data from other laboratories revealed comparable results. The analysis of the structure of the results of cytological investigations according to Bethesda revealed a high rate of the first class (non-informative), which indicates the need for more accurate interaction between clinical physicists and cytologists.

Published: February 2023

Sepsis has been a serious public health concern for a long time and is characterized by disrupted development of specific diagnostic criteria and novel therapies for sepsis is critically dependent on an understanding of the basic mechanisms immune homeostasis accompanied by infection and multiple organ dysfunction as determined assessed by the Sequential Organ Failure. Adult (4 to 6 months) male C57BL/6 mice, animal set in three groups, control group, Cecal Ligation and Puncture (CLP) group, CLP+ Local sympathetic denervation group 8 mice in each group. CLP model for created sepsis and local sympathetic denervation procedure for alleviated the effects of sepsis. Assessment of cardiac function by Millar Instruments, immunofluorescence staining, enzyme-linked immunosorbent assay (ELISA) and RNA extraction and sequencing. Our findings showed that the myocardial injury score and TNF-α level in both tissue and serum were significantly increased in the CLP group. CLP with local sympathetic denervation group mice had lower scores of myocardial injuries. Sepsis augments MCP-1 and KC level in myocardium. After 48 hours after CLP, the myocardial injury score. CLP with local sympathetic denervation alleviates sepsis-induced myocardial injury by inhibiting the NF-κB signaling pathway. Moreover, compared with the Ctrl group, the CLP with local sympathetic denervation group obtained fewer ncRNAs and mRNAs. Inconclusions, the NF-κB signaling pathway is associated with sepsis-induced myocardial injury, and local sympathetic denervation can relieve sepsis-induced myocardial injury by regulating the ncRNAs and mRNAs.

Published: February 2023

In the present study, models were developed to determine the monthly and annual spatio-temporal variation of temperature, precipitation, and solar radiation based on topoclimatic analysis of Arica-Parinacota and Tarapacá in northern Chile. To construct the equations of the topoclimatic model, the data from meteorological stations and physiographic factors (latitude, longitude, altitude, and distance to bodies of water) obtained from a digital terrain model with a resolution of 90 m were compiled in a database. The equations of the topoclimatic model were generated by a stepwise regression with a backward selection technique. The equations for average monthly temperature, precipitation, and solar radiation were determined by linear combinations. The results were statistically significant with coefficients of determination greater than 90%, in addition to being greater than the existing climate databases for this area.

Authors: Shonit Kantroo  , Girish Shakuntal  , Vaibhav K. Gode
Published: February 2023

Background: Neonatal jaundice is generally a benign condition seen during the postnatal period. The non-invasive methods including transcutaneous bilirubinometry have been developed for assessment of neonatal jaundice, transcutaneous bilirubin TcB) meters noninvasively estimate the bilirubin levels by measuring light transmission through the skin of neonates this value is then to be plotted against a chart in order to look for hyperbilirubinemia. Aim was to determine the efficacy of measuring the transcutaneous bilirubin as a screening tool for clinically significant hyperbilirubinemia.
Methods: Study was a cross sectional study conducted under pediatric department of SMBT IMS and RC at tertiary care center after taking the approval from the ethical committee. Total of 110 neonates that appear to be clinically suffering from neonatal jaundice were considered for study after consent from respective parent/ guardian. Neonatal TCB levels and serum bilirubin levels were done. If bilirubin levels lie in phototherapy range, then baby was shifted to NICU and phototherapy treatment was given, and once levels came within normal range after the phototherapy treatment, again serum bilirubin levels were measured in order to compare pre-and post-treatment levels.
Results: Present study showed male preponderance. 64 were male and 46 were female. Majority 61% were full term normal delivery and 39% were LSCS. Mean TCB level was 8.5±2.8. Statistical significance was seen for TCB and sever hyperbilirubinemia.
Conclusions: Present study concluded that hyperbilirubinemia is commonly seen among males. Newborn delivered had hyperbilirubinemia. Statistical significance was seen between TCB level and severity of the disease.  Thus, neonatal TCB levels can be used as a screening test for detecting hyperbilirubinemia in neonates. As TCB is a noninvasive and cost effective it can be used widely as predictor of the disease.

Os resultados evidenciaram importantes transformações na paisagem com expansão das áreas de pastagens e das áreas urbanas, além de expressivas variações das áreas de pastagens degradadas e solo exposto no município, em contrapartida, houve poucas diferenças na evolução de uso e cobertura das áreas florestadas. Este trabalho pretende contribuir com os estudos de evolução da paisagem e subsidiar melhores propostas de planejamento para o uso e a ocupação da terra na área em estudo.
Uso da cartografia enquanto subsídio ao ensino de geografia: o caso da Comunidade de Missão do Sahy - Senhor do Bonfim - BA
Authors: Da Silva Moura Lucélia Nascimento , Souza Sirius Oliveira
Published: February 2023

Desde a Pré-história até os dias de hoje, a Cartografia e a Geografia caminham juntas, ambas servindo de instrumento para que o homem analise o espaço geográfico, suas relações e como está organizado. Este trabalho tem como objetivo discutir a importância da Cartografia enquanto subsídio pedagógico ao ensino de Geografia no Ensino Fundamental. Tal pesquisa se justifica, por perceber que há uma necessidade de trabalhar a Cartografia na disciplina de Geografia e de desenvolver no estudante a capacidade de compreender o espaço a partir do lugar em que está inserido, ciente de que os espaços ao seu redor estão organizados a partir de uma lógica específica, para uma posterior análise de um contexto diferente. Vale ressaltar que, para a construção deste trabalho foi utilizada uma metodologia de revisão bibliográfica e a construção de uma representação da área de estudo, na qual identifica-se uma deficiência em materiais cartográficos disponíveis ao trabalho educativo escolar, uma vez que o tema é de grande importância para o ensino de Geografia. Como resultado do processo, obteve-se o mapa local, bem como discussões importantes acerca do impacto do processo e do produto na formação acadêmica.

Authors: Pereira da Silva Gustavo Henrique , De Costa Trindade Amorim Margarete Cristiane
Published: February 2023

Este artigo buscou analisar os efeitos de áreas agrícolas urbanas na intensidade das ilhas de calor em Florianópolis – SC. Os procedimentos metodológicos consistiram na coleta de dados em 12 pontos fixos distribuídos em 3 áreas agrícolas urbanas, 8 em áreas intraurbanas e 1 em área sem a presença de materiais construtivos, no mês de fevereiro de 2019. Os resultados obtidos revelaram a variação espacial e temporal da intensidade da temperatura do ar, associada aos usos e ocupação da terra no entorno e aos diferentes sistemas atmosféricos atuantes no mês de estudo. Durante o período diurno (9h, 15h), foram detectadas as maiores intensidades da temperatura do ar, em que os pontos localizados ao Sul da ilha de Santa Catarina (pontos 1, 2, 3 e 4), incluindo os de agricultura urbana (pontos 1 e 2), com cobertura vegetal, se apresentaram mais aquecidos que os demais. Durante a noite, as intensidades das temperaturas diminuíram, com destaque para as áreas agrícolas estudadas, que em muitos dias converteram-se em ilhas de frescor, o que demonstra a importância desse tipo de uso da terra na redução das temperaturas em ambiente urbano.

AIM: To investigate the progression of myopia and risk factors among university students in central China.
METHODS: A total of 7359 first-year undergraduate students at Huazhong University of Science and Technology in central China were recruited to the study and invited to a centralized clinic for medical examination, including optometry, and re-examined after one year. Correlation analyses were performed to assess the associations between one-year myopia progression and various parameters.
RESULTS: The spherical equivalent refraction for the overall population was -3.14±2.28 D at baseline. The rate of myopia progression over 0.50 D after one year was 41.9%, and the 1-year progression of myopia was -0.47±0.58 D. There was no difference of mean 1-year myopia progression between male and female or difference among age group. The myopia progression of original myopia was severer than progression of new-onset myopia. There was also difference of mean myopia progression among different degrees of myopia at baseline. The under corrected eyes had a higher percentage of myopia progression than well corrected eyes (χ2=7.90, P<0.01). There was no correlation between myopia progression and height, weight, body mass index, hemoglobin (Spearman correlation, ρ=-0.078, -0.152, -0.170, -0.096, respectively, all P>0.05).
CONCLUSION: Myopes still progress in undergraduate students, especially in high myopes.

By the example of tubular oxygen-permeable membrane of mixed-conducting LaGa0.65Mg0.15Ni0.20O3-Δ operating under oxygen chemical potential gradients in the regime of hydrocarbon oxidation, modeling of chemically induced strains in the dense ceramic material has been carried out. The membranes with various radii in different reactor configurations were simulated. Analysis of the distributions of oxygen chemical activity and chemically induced stresses showed that, for minimization of mechanical stresses, the most advantageous basic configuration involves supplying atmospheric air inside a tubular membrane and opposite directions of the gas flows. The maximum stresses are observed in the region of reducing gas mixture injection, where a zone with an essentially constant oxygen chemical potential on the membrane surface may exist for many reactor configurations. The size of such zones formed due to specific features of the gaseous phase component distribution and/or ceramic reactor configurations, has a significant effect on the mechanical stress distribution.

Published: February 2023

O texto reflete sobre um exercício colaborativo na proposição, condução e avaliação de uma experiência de formação docente no Curso de Licenciatura em Educação do Campo, por meio do qual se buscou envolver os estudantes em uma ambiência de cocriação de processos formativos que superassem, ao menos em parte, a separação estanque entre ‘teoria’ e ‘prática’ em dois componentes curriculares, trabalhados de forma integrada, a saber: Metodologias do Ensino de Linguagem e Estágio Supervisionado, assim como certos limites impostos pelo modelo de ensino remoto emergencial durante a pandemia de Covid-19. Os resultados preliminares dessa experiência apontam acertos e avanços nas escolhas teórico-metodológicas concernentes ao campo de estudos da linguagem aliados ao uso adequado e diferenciado de dispositivos EaD; mas indicam, na mesma intensidade, a necessidade de se olhar mais atentamente os riscos implicados na operacionalização de atividades relacionadas à prática docente quando estas acontecem em ambientes virtuais.
FEIRA NA PALMA DA MÃO: UMA PLATAFORMA DIGITAL PARA A VENDA DIRETA DOS PRODUTOS DA AGRICULTURA FAMILIAR

Published: February 2023

Em virtude da pandemia instalada em todas as partes do mundo pelo Covid-19, as relações comerciais sofreram muitas mudanças. O avanço das tecnologias digitais que permitem a comunicação instantânea e em tempo real independente da distância geográfica onde estão as pessoas, mudaram diversas atividades cotidianas, dentre elas, a forma de comprar e vender. No caso da agricultura, a venda direta dos produtos agrícolas aos consumidores finais, através das redes sociais, emerge como uma nova forma de negócio rural. Entretanto, a aproximação entre as partes interessadas ocorre, na maioria das vezes, de maneira informal, cabendo aos produtores e consumidores a tarefa de “se encontrarem” para comercializar. Nesse sentido, o que o projeto se propôs foi atuar como agente articulador dessas duas pontas para que essa aproximação fosse facilitada. Para tanto, foi desenvolvida uma metodologia de Assistência Técnica e Extensão Rural (ATER) com o objetivo de criar uma plataforma digital (aplicativo e site) que permitisse que esses negócios fossem realizados com mais rapidez e credibilidade. A área de pesquisa os locais que já têm produtores e consumidores capazes de atender a essa nova dinâmica do mercado. Assim foram escolhidos os oito municípios que possuem Sistema Unificado Estadual de Sanidade Agroindustrial Familiar de Pequeno Porte (SUSAF) e incluídos outros quatro devido à proximidade da Região Grande Vitória, onde está localizada a maioria dos consumidores do Estado do Espírito Santo.

Published: February 2023

Este trabalho teve por objetivo analisar as compreensões de professores da Educação Infantil sobre o trabalho pedagógico com alunos com Transtorno Espectro Autista nas escolas municipais de Educação Infantil do município de Jaguarão. A pesquisa foi realizada com seis professoras da Educação Infantil por meio de um questionário com questões relacionadas à definição de autismo, inclusão no ensino regular e formação docente. Nesse contexto foi possível perceber muitas dificuldades na inclusão de crianças autistas no ensino regular, dentre elas omissão do Estado na garantia de estrutura das escolas e falta de formação docente adequada. Diante dos resultados, concluímos que o processo de inclusão é lento, porém já é discutido nas escolas e existem algumas políticas públicas de acesso, entretanto não de permanência das crianças autistas. E ainda que os sujeitos da pesquisa reconhecem uma falha em sua formação para trabalhar com inclusão.

Published: February 2023

A nova edição da Classificação Internacional de Doenças (CID 11), em vigor desde fevereiro de 2022, apesar de explicitar que o Transtorno do Espectro do Autismo (TEA) não é doença, declara que as pessoas com autismo possuem déficits persistentes na interação e comunicação social, somado a padrões de comportamento e interesses restritos, repetitivos e inflexíveis, características que, quando não tratadas precocemente, carretam prejuízos ao longo de toda vida. Entre 2019 e 2021, o enfrentamento da pandemia do Coronavírus exigiu isolamento social, situação que atingiu especialmente os indivíduos mais vulneráveis, dentre eles as pessoas com TEA, que tiveram uma quebra abrupta da rotina, justamente uma das maiores dificuldades para esse público. Nesse contexto, este artigo ressalta contribuições que os estudos na área da Psicologia Ambiental (PA) podem oferecer para a compreensão do comportamento socioespacial das pessoas com autismo. Para fundamentar a argumentação foram analisadas 64 Lives sobre autismo disponibilizadas na internet entre março e agosto/2020, das quais 22 remetem a assuntos relacionados à PA. A análise do material coletado mostrou o potencial da PA para: (i) ajudar a explicar determinados comportamentos presentes no TEA; (ii) sugerir intervenções ambientais que podem ser feitas por profissionais e familiares a fim de reduzir alguns problemas detectados.
Mixed Martial Arts As a Way of Life: Going Beyond The Black Belt And Engaging in Life-Long Learning
Authors: Rusticus Shayna , Dumoulin Amanda Rose
Published: February 2023

In this qualitative study, we explored the experiences of 10 adults who trained in mixed martial arts (MMA) to understand the meaning they ascribed to attaining the black belt and their martial arts journal overall. Using a conventional content analysis, four themes were derived from the data: importance of the black belt, benefits of training in MMA, dealing with injuries, and being part of the MMA community. Training in MMA was very positive, with both individual benefits (improved physical and mental health, skill development, and personal growth) and interpersonal benefits (relationship development and sense of community) being reported. Self-determination theory (Ryan & Deci, 2000) and goal setting theory (Locke & Latham, 2002) are used to discuss participants’ motivation in their pursuit of the black belt and continued training.
Engolo and Capoeira. From Ethnic to Diasporic Combat Games in the Southern Atlantic
Authors: Assunção Matthias Röhrig
Published: February 2023

This article provides a re-examination of the main Afrocentric narrative of capoeira origins, the engolo or ‘Zebra Dance’, in light of historical primary sources and new ethnographic evidence gathered during fieldwork in south-west Angola. By examining engolo’s bodily techniques, its socio-historical context and cultural meanings, the piece emphasises its insertion into a pastoral lifestyle and highlights the relatively narrow ethnic character of the practice in Angola. This analysis and the comparison with capoeira helps us to develop certain hypotheses about the formation, migration, and re-invention of diasporic combat games between southern Angola and coastal Brazil, and more broadly, to increase our understanding of how African cultures spread across the southern Atlantic.
The British Ju-jitsu Society and the influence of Kodokan Judo on early jujutsu in the U.K.
Authors: Brough David , Bradić Slaviša , Callan Mike , Gatling Lance , Jones Llyr
Published: February 2023

In the United Kingdom (U.K.) in the late Victorian and early Edwardian eras there was an explosion in the popularity of the Japanese martial art jujutsu, with seemingly invincible Japanese exponents touring and taking on all comers in the music halls. As this early wave of popularity subsided a number of organisations were established to continue the practice of jujutsu, and other Japanese martial arts. Most notable of these was The Budokwai in London, established in 1918 by Gunji Koizumi, which from 1920 would become one of the foremost judo clubs in the West. Recent discoveries shed light on another organisation from this era called the British Ju-jitsu Society (BJS). Established in 1926, the BJS co-existed with The Budokwai and had member clubs throughout the U.K. Here, we provide an overview of the BJS, its activity, and insights into its operation and legacy.
The role of diffusion-weighted imaging in the diagnosis of early kidney damage
Authors: KAVAK Şeyhmus
Published: February 2023

Objective: This study aimed to determine a threshold value for distinguishing early-stage chronic kidney disease (CKD) from moderate and advanced stages as well as patients with early-stage CKD from those with normal renal function using apparent diffusion coefficient (ADC) and normalized ADC values.
Methods: This retrospective study enrolled 257 patients. Diffusion-weighted images were obtained with a set of b = 50,400,800 values. In each patient, six ADC values were measured from upper, middle, and lower areas of both kidneys, and three ADC values were measured from the spleen. Patients with CKD were classified into five subgroups and healthy patients were classified into two subgroups according to their glomerular filtration rate (GFR).
Results: The renal ADC values were found to be positively correlated with GFR (r = 0.790, p < 0.001) and negatively correlated with creatinine levels (r = −0.709, p < 0.001). The mean ADC values of the stage 1 and 2 CKD groups were found to be significantly higher than those of advanced-stage CKD groups (p < 0.001), and these values were significantly lower in the stage 1 and 2 CKD groups than in the healthy group (p < 0.001). With a cut-off value of ≥1.791 for ADC, the sensitivity was 76.5% and the specificity was 85% while distinguishing between patients with early- and advanced-stage CKD.
Conclusion: Renal and normalized ADC values are strongly correlated with CKD stages, and with the use of appropriate threshold values, the difference between early and advanced stages of CKD can be predicted.

Jednym z niezbędnych parametrów do określenia warunków termicznych zbiornika geotermalnego jest współczynnik przewodności cieplnej skał. Przewodność cieplna zależy od innych własności skał, takich jak skład mineralny i porowatość. Do obliczenia wartości tego parametru można więc stosować modele matematyczne uwzględniające zarówno zawartość objętościową i przewodność cieplną poszczególnych minerałów i roztworów porowych, jak i strukturę skały. W pracy wykorzystano różnego rodzaju modele, od najprostszych, warstwowych, po bardziej skomplikowane modele inkluzji niesferycznych. Obliczone wartości zweryfikowano na podstawie pomiarów laboratoryjnych przewodności cieplnej. Badania wykonano na próbkach dolomitu charakteryzujących się mało zróżnicowanym składem mineralnym, a jednocześnie dużą zmiennością porowatości (od 3% do 27%). Parametr porowatości ma widoczny wpływ na dopasowanie poszczególnych modeli matematycznych. Najlepszą zbieżność wartości pomierzonych i wyliczonych uzyskano w przypadku próbek o wysokiej porowatości (powyżej 25%) za pomocą modelu średniej arytmetycznej. W przypadku próbek o niższej porowatości najlepsze dopasowanie otrzymano przy wykorzystaniu modelu średniej harmonicznej, modelu inkluzji sferycznych (przypadek skały składającej się ze sferycznych ziaren rozproszonych w roztworze porowym) oraz modeli inkluzji niesferycznych (przypadek porów w formie szczelin o kształcie dysków). Wszystkie modele dobrze odzwierciedlają trendy zmienności otrzymane dla wartości pomierzonych. Uzyskane korelacje charakteryzują się wysokimi współczynnikami determinacji R2, przekraczającymi 0,86. Wysoka jakość korelacji pozwoliła na wprowadzenie poprawki umożliwiającej przybliżenie wartości wymodelowanych do rzeczywistych. Otrzymane wyniki pozwoliły na dobór optymalnych modeli umożliwiających ocenę wartości przewodności cieplnej dolomitów na podstawie składu mineralnego. W przypadku skał o bardzo wysokiej, przekraczającej 25%, porowatości najlepiej dopasowuje się model średniej arytmetycznej. W przypadku pozostałych próbek najlepszą zgodność wartości wyliczonych i pomierzonych uzyskano po zastosowaniu poprawki; wyniki są bardzo zbliżone dla wszystkich zastosowanych modeli.

Ze względu na wysoką cenę lekkich rop większość rafinerii skłania się do zakupu większych ilości tańszych rop „okazyjnych”, które są cięższe i zawierają wyższe stężenia siarki i kwasów naftenowych. Takie podejście doprowadza do większej częstotliwości prac serwisowych związanych z oczyszczaniem instalacji procesowej w rafinerii. Na szczęście zrozumienie przyczyn i metod łagodzenia wytrącania się zanieczyszczeń ropopochodnych uległo ostatnio znacznej poprawie dzięki opracowaniu narzędzi do przewidywania i identyfikacji. Co zaskakujące, 90% zanieczyszczeń ropopochodnych w rafinacji ma tylko kilka wspólnych przyczyn. Analiza osadu zwykle pozwala na zidentyfikowanie pierwotnej przyczyny, którą potwierdza odnalezienie prekursora tego niekorzystnego zjawiska w ropie naftowej przepływającej przez zanieczyszczoną jednostkę instalacji. Odpowiednie rozpoznanie zagadnienia może wprowadzić szereg potencjalnych metod łagodzących, z których dana rafineria może wybrać najlepszą do wdrożenia. Każdy kraj na świecie dąży do osiągnięcia jak największego bezpieczeństwa energetycznego, a tym samym do dywersyfikacji dostaw ropy i innych surowców. W przypadku ropy, gdy pozyskiwana jest ona z różnych źródeł, generuje się dodatkowy problem, a mianowicie kompatybilność. Okazuje się, że po zmieszaniu niektóre ropy wykazują tendencje do wytrącania osadów w zbiornikach magazynowych, a następnie w ciągu logistycznym. W jednej z poprzednich prac opracowano skuteczną metodę filtrowania pozwalającą na określenie kompatybilności rop i ich mieszanin. W obecnej pracy skoncentrowano się na tym, aby nowa metoda pozwoliła na szybszą możliwość wykonania pomiaru kompatybilności przy jednoczesnej możliwości ponownego wykorzystania tej samej próbki. Opracowany nowy sposób badań kompatybilności z wykorzystaniem mikroskopu (ang. high-pressure microscope, HPM) zastosowano do dwóch rop pochodzących z różnych kierunków dostaw. Pomiary wykonano dla rop i ich mieszanin w temperaturze 120°C i pod ciśnieniem 25 bar. Pomiar kompatybilności rop metodą filtrowania wykorzystano do celów porównawczych, gdzie masa odseparowanego osadu na specjalistycznych filtrach stanowiła wyznacznik kompatybilności badanych rop.

Personalizm ekonomiczny i jego zasady w ujęciu G.M.A. Gronbachera
Authors: Urgacz Paweł
Published: February 2023

The dialog that has been conducted for a few years between a group of Christian social thinkers
and economists on moral aspects of economic activity has led to the creation of a new science discipline
called economic personalism. On the one hand it stipulates the need to express economic processes
within ethical categories, on the other hand it perceives the necessity to elaborate a strong economic
theory. Economic personalists refer to the works of those thinkers who returned to the basic economic
inspiration as a field belonging predominantly to moral philosophy. This school is sometimes called
the Austrian School or the School of Classical Liberalism.
A significant role in the economic personalism development was performed by its forerunners
who noticed what was lacking in the previous interpretations of Catholic social thought. Among
the there are John Paul II, Michael Novak, Rocco Buttiglione and the Acton Institute.
The intellectual sources of economic personalism are mainly related to concept of personalism
developed in Poland. Its specific thesis, seen in the maxim that “each person ought to be affirmed for
the sake of it itself” also relates to the economic life.
Economic personalists formulate principles that are spokesmen in order to promote a free society
built on virtues. They are expressed in the following way: pre-eminence of a human being: economy
and human dignity; human capital: creation and creativity; dignity of human work: calling for
enterprise, integral development of human being, manufacture and personalism, participation, economic
common wealth, helpfulness, market restrictions; preferential option for the poor: solidarity and social
equity.
Chrześcijańska przeszłość dla kultury integrującej się Europy
Authors: Gryżenia SDB Ks. Kazimierz
Published: February 2023

The last few years are the time of the ongoing integration of Europe and its vivid discussion about
it. The thorny issue is the role and the place of Christianity in the life of Europe. Pope John Paul II had
authoritatively taught on the issue. His teaching is a kind of antidote against those who are in favour of
Europe without God.
The European culture is not a monolith since it is inhabited by many nations with a different
characteristic but all are rooted in the same values of the Good News acknowledged on the Continent.
The present time – and especially the centuries after the Enlightenment – seems to be the time of
abandoning Christianity. As the result of such a process, Europe witnessed two totalitarian systems
responsible for numerous crimes. A human being wanted – without God’s participation - to decide
about right and wrong. They were tempted like the first parents in Eden. They were changed from godlike
humans to objectified ones – from “homo sapiens to homo demens”.
John Paul II and many authors dealing with the processes of mankind underlined the need to build
unity in Europe in close connection to Christianity. Christianity is an important element of culture in
which the man is not restricted to his mortal life but opens up for a supernatural perspective. Through
Christianity the European culture is richer and the man fully developed. Taking Christianity into
consideration in his life, man can discover the truth about himself and his true relation to God.
Only the truth allows man to grow and achieve his perfection, whereas falseness condemns him to
the degeneration.

Diagnozowanie ubóstwa ekonomicznego na przykładzie Regionu Pomorskiego
Authors: Plecka Małgorzata
Published: February 2023

The main goal of this paper is a collation of methods for diagnosing subjective poverty.
The comparison concerns the methods of identification of poverty in the sub-regions of the Pomeranian
region. The methods of identification proposed by the author indicate that the proposed methods
identify poverty much more precisely than the universal methods. It can be considered to carry on
the policy of limiting poverty areas based on the local monitoring. The assembled conclusions can allow
improvement of accuracy of directing social help and at the same time can increase acceptance of
the rules used in administering this help.

Background: Stress is a reflex reaction initiated by animals due to the inability to cope with a stressor, which may cause discomfort, illness, or sometimes death. The present study aimed to investigate the anti-cold stress potential of aqueous extract of Zanthoxylum armatum DC. (fruit kernel) in Wistar albino rats. Methods: Rats were divided into five different groups (n=6). Cold stress was induced by exposing rats to cold environments during peak winter for 4 h/day for the 10-day experimental period. Groups 1 and 2 kept as healthy and stress-induced groups respectively. Group 3 received the Withania somnifera (100 mg/kg body weight) as a standard adaptogen. The Group 4 and 5 received Z. armatum at a dose rate of 250 and 500 mg/kg body weight, respectively. Haemato-biochemical, stress and hormonal profile of all the groups were analyzed. Result: A significant hyperglycemia was observed in a stress-induced group compared to the healthy group. Elevated lipid peroxidase (LPO) and declined superoxide dismutase (SOD) levels were recorded in stress-induced group concerning the healthy group. Hormonal analysis exhibited significant hypercortisolism with significant reduction in thyroxine (T4) values in stress- induced group. However, levels of LPO, SOD and hormonal parameters were recovered towards normal levels in a group 5, receiving a extract of Z. armatum (500 mg/kg). The present study revealed the anti-cold stress potential of aqueous extract of Z. armatum (fruit kernel) at a dose rate of 500 mg per kg body weight in rats.

Dünya Klasiği Masallarındaki Çocuk İstismarı ve İhmali Durumunun İncelenmesi
Authors: EROL Dilek , CENGİZ Şerife , DEMİR Ramazan , IŞIK Ahmet Erkam
Published: February 2023

Dünya klasikleri, yaklaşık iki asırdır dünyanın dört bir yanından çocukların okuduğu, dinlediği, kahramanlarıyla özdeşim kurdukları masallar arasındadır. Bu araştırma Uşak ili İskender Pala İl Halk Kütüphanesi’nden 2021 yılında “okul öncesi dönem” kategorisinde en çok ödünç alınan 15 dünya klasiği masallarındaki çocuk istismarı (fiziksel, cinsel, duygusal) ve ihmali türlerine yer verilme durumunu incelemek amacıyla yapılmıştır. Araştırma, nitel desende tasarlanmış, masallar doküman analizi tekniğiyle incelenmiş ve verilerin analizinde betimsel analiz tercih edilmiştir. Araştırmanın sonuçlarına göre, masallarda en fazla duygusal istismar ifadelerine (n=60), daha sonra fiziksel istismar ifadelerine (n=19), en az ise duygusal ve fiziksel ihmal ifadelerine (n=5) rastlanmıştır. Masallarda cinsel istismara yönelik herhangi bir bulguya rastlanmamıştır. Araştırmada yer alan masalların bazıları her ne kadar psikolojik danışman onaylı ya da yeniden yorumlanmış olsa da masalların gözden geçirilmesi, çocukların duygusal gelişimine zarar vermeyecek şekilde yeniden düzenlenmesi ve istismar ve ihmal ifadelerinin çıkarılması önerilmektedir.

Początki teorii filmu w Japonii (prolegomena)
Authors: Loska Krzysztof
Published: February 2023

Seeking an answer to the question once posed by Tadao Satō: “Is there a Japanese film theory?,” the author of the article makes a critical review of the publications which appeared in the first decades of the 20th century. Loska draws attention to both the influence of Western philosophical trends (neo-Kantism) and the importance of native aesthetic inspirations (the Kyoto school). When discussing theoretical concepts, the author focuses on the issues raised by researchers related to the psychological conditions of reception (Yasunosuke Gonda), the search for specific properties of the new medium and its relation to other arts (Jun’ichirō Tanizaki), the impact of film on the senses and the embodied dimension of visual perception (Masakazu Nakai), the phenomenon of technological reproduction and the impression of reality (Jun Tosaka), and the idea of “machine realism” (Takeo Itagaki).
