Published: November 2023

: Background: Community-acquired pneumonia (CAP), one of the most common infectious diseases, is the third leading cause of death worldwide. To stop the spread of serious sickness and keep the initial infection under control, the innate immune response is crucial. Cathelicidin, a potent antimicrobial peptide that may kill germs directly and alter the immune system's response to infection, is an essential component of this response. The main goal of the study is to investigate the association between CaLL37 and the severity of CAP in young patients. Methodology: 120 CAP cases and 165 controls made comprised the 285 participants in this case-control study, whose ages varied from 1 to 18 months. Calculated and compared cathelicidin levels for CAP and control participants as well as the pneumonia-causing agent. People who were thought to have COVID-19 CAP were excluded. Results: The participants' mean age was 9.7 (range of 1 to 18) months. In 46.2%, 35%, and 18.8% of cases of CAP; bacterial, viral, and mixed causative agents, respectively, were detected. Among the individuals, only 6.8% received mixed feeding, compared to 42.1% who used artificial feeding and 51.1% who exclusively breastfed. The mean total serum contained 8.6 ±6.7 ng\ml of CaLL37. CaLL37 serum levels were comparable between the two study groups (p>0.05). The levels of CaLL37 were comparable (p>0.05) among patients with CAP when compared according to the causative agents, while plasma CaLL37 levels were higher among babies on artificial feeding (p-0.001). The ROC assays revealed that CaLL37 plasma levels were unable to differentiate between bacterial and viral pneumonia or between persons who had pneumonia and healthy subjects. However, the CaLL37 can discriminate between infants who are breastfed and those who are fed by a bottle considerably (p-0.001, AUC=0.748, sensitivity=0.673, specificity=0.637, and 95%CI of o.675 - 0.820). Conclusion: According to the study, CaLL37 is capable of determining the difference between infants who are breastfed and those who are fed artificially. However, it is difficult for cathelicidin to distinguish between various CAP causes as well as between CAP patients and healthy controls.

Published: November 2023

The application potential of nanofiltration (NF) method on the separation of 1,3-propanediol (1,3-PDO) from synthetically prepared fermentation broth was investigated. The rejection tests at different pressures (10, 20, 30 bar) and pH values (7 and 10) were performed on laboratory scale using Desal DL-5 NF membrane. The rejection of succinic acid, having the molecular weight larger than or closer to the molecular weight cut-offs (MWCOs) of Desal-5 DL NF membrane was 100% independent of operating pressure and pH. The results of this study clearly showed that NF process is a very promising pretreatment step for the removal of volatile organic acids from the fermentation broth.
Hydrophilic Nanocomposite Membranes for the Pervaporation Separation of Water - Ethanol Azeotropic Mixtures
Authors: Jose Thomasukutty , George Soney C , Thomas Sabu
Published: November 2023

Bentonite nanoclay reinforced Poly (vinyl alcohol) (PVA) nanocomposite membranes were used for the separation of azeotropic composition of water â€“ ethanol mixtures by pervaporation process. Fourier â€“ transform infrared (FTIR) spectroscopic studies revealed the interaction of bentonite nanoclay and the PVA matrix. The dispersion and distribution of nanoclay in the polymer matrix was demonstrated by transmission electron microscopic analysis (TEM). The intrinsic membrane properties with filler loading were also investigated. The results indicate that the hydrophilic nature of the nanoclay influenced the pervaporation to a greater extent. The hydrophilic nature and surface roughness of the nanocomposite membranes was analyzed by atomic force microscopic (AFM) analysis. The pervaporation process illustrates that the permeation flux increases and the separation factor decreases with nanoclay loading. The instrinsic selectivity, which reflects the membrane performance was maximum for 1 wt% clay loaded membranes. PVA with 1 wt% nanoclay loading showed better pervaporation performance. The separation factor of the 1 wt% nanoclay membranes increased to 13, i.e. nearly 4 times more than that of neat PVA membranes. Membrane selectivity also increased to 254% than that of pristine PVA membranes. Thus at lower filler loading, maximum separation was achieved. The increase in nanoclay loading is favorable to improve intrinsic permeance at the cost of decrease in selectivity
A Comparative Study on Sulfonated PEEK and PVDF Blend Membranes for Direct Methanol Fuel Cells
Authors: DÃ¶nmez GÃ¶knur , DeligÃ¶z HÃ¼seyin
Published: November 2023

Various polymeric blend membranes based on sulfonated poly(ether ether ketone) (sPEEK) and poly(vinylidene fluoride) (PVDF) are prepared by solution casting method for direct methanol fuel cells (DMFCs). Physicochemical properties of the membranes are studied after blending sPEEK with PVDF in different ratios. It is found that the thermal stabilities of all blend membranes are above 200oC which is sufficiently high for use in DMFC. Water uptake values of the blend membranes vary between 9-20% as a function of the blend composition. Similar to the water uptake property, proton conductivity values and surface hydrophilicity of the samples increase with sPEEK portion in the blend. Water uptake of sPEEK30/PVDF70 blend membrane is about 9.2%, the proton conductivity of this membrane is 0.8 mS.cm-1, and the methanol permeability of sPEEK30/PVDF70 blend membrane is about 1/10 that of untreated NafionÂ®117 reported in the literature. Based on the results, it is concluded that the sPEEK/PVDF polymer blends can be considered as a candidate membrane for DMFC applications considering their controllable properties, cheapness and easy preparation.

Authors: Ruby-Figueroa RenÃ© , Conidi Carmela , Cassano Alfredo
Published: November 2023

Orange press liquor, a by-product of the orange juice production, was clarified by cross flow ultrafiltration (UF), on laboratory scale, by using polysulphone hollow fibre membranes with molecular weight cut-off of 100 kDa. The effect of operating conditions, such as transmembrane pressure, feed flow rate and temperature, on fouling index, total resistance and permeate flux was investigated.Analysis of the results revealed that in the range of operating values investigated permeate flux increased with temperature, pressure and feed flow rate according to concentration polarization models. Total resistance and fouling index increased with pressure and decreased with feed flow rate. An increase of temperature in the range 15-35 Â°C reduced the value of total resistance but enhanced the fouling index.According to the experimental results the optimum conditions to maximize permeation fluxes were found to be 1.4 bar of pressure, 35Â°C and a feed flow rate of 245 L/h; on the other hands, operating conditions of 0.2 bar, 15 Â°C and 245 L/h were identified as the best ones to minimize membrane fouling.

Published: November 2023

Membrane processes are used extensively in biomedical applications. This state of the art review presents the main applications including renal kidney, blood filtration, blood oxygenator, artificial liver, artificial pancreas, and drug delivery devices. For well-established treatments like dialysis, plasmapheresis, and blood oxygenator, the techniques are summarized by presenting membranes used, devices, configurations and treatments. The artificial liver and the artificial pancreas are not clinically used and some main aspects related to the development of these devices are given, including configurations and liver or pancreatic cells. Finally, drug delivery devices based on membranes, which are an important area in pharmaceutics, are summarized by focusing on diffusion and transdermal delivery systems, as well as colloids like liposomes and nanocapsules. These colloids with nanometric size are surrounded by a lipidic or polymeric thin membrane which controls drug transfer to the surrounding medium.

Published: November 2023

The forecasts in the industrial chemistry field evidenced the growing demand of propylene, and the necessity to develop effective processes able to sustain the market. Selective propane dehydrogenation is emerging as the most competitive technology for the production of propylene, on the other hand, the well-known drawback closely linked to the high temperature required to reach a sustainable propane conversion and the coke formation that suppress the catalytic stability still requires appropriate solutions. In this sense, the process intensification through the combination of hydrogen permselective membranes and the reduction of operating temperature could strike the targets of very high propylene selectivity and a quite high conversion value. Since the integration of membrane units in a process required a revision of the operating conditions, the effect of feed composition and temperature was investigated, in order to determine the optimal operating parameters window to operate the system, and assess the overall concept performance. A commercial membrane was characterized, in order to understand the suitability in the propane dehydrogenation process that may cause a severe membrane deactivation due to coke deposition. Finally, specific tests on a simulated process configuration, obtained in an open architecture, confirmed that the smart combination of PDH catalytic reactors and Pd-based membranes was able to allow a reduced operating temperature, so increasing propylene selectivity, and to overcome typical thermodynamic limitations related to a traditional configuration.

Published: November 2023

У цій роботі обговорюється вплив шорсткості поверхні та фізико-хімічних властивостей поверхні на початкову адгезію фосфатів до сталі. Зразки сталі, використані в цьому дослідженні, виготовлені з низьколегованої сталі A36. Фосфат був видобутий в районі Бен-Гурір-Марокко і в цій роботі використовувався у вигляді гранул, спресованих під різними тисками. Сталеву поверхню обробляли двома методами попередньої обробки поверхні – хонінгуванням та горизонтальним фрезеруванням. Досліджено вплив цих процедур на морфологію поверхні, шорсткість, поверхневу енергію та гідрофобність. Вимірюючи кут контакту на поверхнях фосфатних гранул і підкладок з низьколегованої сталі А36, ми змогли визначити деякі фізико-хімічні параметри та розрахувавши поверхневу енергію. Крім того, шорсткість кожного сталевого зразка була досліджена за допомогою вимірювача шорсткості та металургійного мікроскопа. Отримані результати показали, що фосфатована поверхня піддається впливу дисперсійних сил і має гідрофільний характер. Для поверхонь різних підкладок зі сталі А36 добре досліджено вплив шорсткості, отримано мінімальну поверхневу енергію як для попередньої обробки (хонінгування та горизонтального фрезерування), так і для визначеної шорсткості. Цей результат може бути використаний для підготовки поверхонь з мінімальною поверхневою енергією для мінімізації енергії руйнування і, отже, мінімізації адгезії та засмічення фосфатами сталі.

Хімічні джерела енергії набувають стрімкого розповсюдження у повсякденному житті людини. Ппереважна кількість батарей, що виробляються, відносяться до літій-іонних. Тому питання, пов’язані з поводженням відпрацьованих батарей, зокрема літій-іонного типу, є актуальними з ресурсної, екологічної, соціально-економічної точок зору. В роботі проаналізовані сучасні підходи до утилізації відпрацьованих літій-іонних батарей та надана принципова схема утилізації. Аналіз сучасних розробок та схем дозволив авторам запропонувати екологічно дружню схему утилізації відпрацьованих літій-іонних батарей шляхом біовилуговування. Схема включає підготовку чорної маси до переробки шляхом механоактивації у вертикальному вібраційному млині з подальшим розкладанням хімічних сполук цільових компонентів та переведення їх у розчинну форму. Умови проведення біотехнологічного циклу за участю метаболічного потенціалу ацидофільних мезофільних мікроорганізмів: кількість відхідної маси/бактеріальна суспензія у межах 1 : 44–1 : 56; температура середовища 29–30 °С; значення показника рН в діапазоні 2.2–4.0. На відміну від традиційних схем, запропонована технологія не передбачає пірометалургійного підходу та дозволяє ефективно підготувати чорну масу до вилучення металів та графіту за допомогою дії мікроорганізмів.

У роботі розглянуто адгезійну міцність електроосаджених покриттів нікелю, заліза, міді та цинку на мідній та сталевій підкладках. Для визначення теоретичних значень адгезійної міцності запропоновано теоретичний підхід до визначення адгезійної міцності на межі метал-метал. Авторами на основі аналізу механізму адгезії і природи контактної взаємодії отримано аналітичний вираз для розрахунку значень адгезійної міцності для певних пар металів, проте знаходження точного значення ряду величин, що входять у цей вираз, наприклад, питомої енергії зв'язку та модуля пружності, становить великі труднощі. Розрахунок енергії взаємодії атомів покриття та підкладки проводили за методом теорії функціоналу густини. У результаті було отримано теоретичні значення адгезійної міцності електроосаджених покриттів нікелю, заліза, міді та цинку на мідній та сталевій підкладках, які добре узгоджуються з експериментальними значеннями адгезійної міцності. Однак, існуючі розбіжності між теоретичними та експериментальними даними викликані певними труднощами знаходження питомої енергії зв'язку та модуля пружності, які пов'язані зі складністю моделювання реальної структури як плівки, так і підкладки. Пошуки вирішення цих питань стануть предметом подальших досліджень.
SNI e a produção de contrainformações à imprensa paranaense e catarinense sobre as Operações Marumbi e Barriga Verde (1975-76)
Authors: Neves Júnior José Wilson Assis , Lanza Fabio
Published: November 2023

O presente artigo analisa os processos de produção e difusão das contrainformações a partir dos arquivos inéditos da agência Curitiba do Serviço Nacional de Informações (SNI), relativos às Operações Marumbi (PR) e Barriga Verde (SC) que perseguiram militantes políticos e partidários do PCB nos anos de 1975 e 1976. Para subsidiar a análise e compreensão sob a perspectiva da pesquisa documental, as fontes foram intencionalmente selecionadas no arquivo do SNI dos estados do Paraná e Santa Catarina, que está em processo de sistematização.  Como resultados, identificou-se duas frentes distintas da produção de contrainformação que foram distribuídas para ampla divulgação nos órgãos de imprensa: 1º) informes oficiais produzidos por agentes da repressão; 2º) mensagens com autoria atribuída às vítimas que se arrependeram da atuação subversiva. Contudo, em ambas as frentes, foram identificados os elementos ideológicos do anticomunismo característico da doutrina de Segurança Nacional.

Published: November 2023

Background and aims

Gaming disorder [GD] risk has been associated with the way gamers bond with their visual representation (i.e., avatar) in the game-world. More specifically, a gamer's relationship with their avatar has been shown to provide reliable mental health information about the user in their offline life, such as their current and prospective GD risk, if appropriately decoded.

Methods

To contribute to the paucity of knowledge in this area, 565 gamers (Mage = 29.3 years; SD =10.6) were assessed twice, six months apart, using the User-Avatar-Bond Scale (UABS) and the Gaming Disorder Test. A series of tuned and untuned artificial intelligence [AI] classifiers analysed concurrently and prospectively their responses.

Results

Findings showed that AI models learned to accurately and automatically identify GD risk cases, based on gamers' reported UABS score, age, and length of gaming involvement, both concurrently and longitudinally (i.e., six months later). Random forests outperformed all other AIs, while avatar immersion was shown to be the strongest training predictor.

Conclusion

Study outcomes demonstrated that the user-avatar bond can be translated into accurate, concurrent and future GD risk predictions using trained AI classifiers. Assessment, prevention, and practice implications are discussed in the light of these findings.
Bilingual literacy learning in adult education
Authors: Francis Norbert
Published: November 2023

Community-based literacy teaching workshops attend to the learning needs of new students who have not been able to benefit from enrollment as children in the public school system. The following report from the field calls attention to the special circumstances of this heterogeneous group of literacy learners. The workshop described here engages learners who are literacy learners as well as second language learners of the national language, in this case Spanish. Literacy learning proceeds in parallel with second language learning. The report summarizes a series of informal interviews with students and their teacher and observation of their adult literacy program, during a period of approximately ten years. As such it provides preliminary findings for better understanding the problems of community literacy programs in bilingual communities in general. The tasks of learning to read and write present themselves in a special situation of language contact, that of community language and national language.

Emigracyjne konstatacje Jerzego Giedroycia i Gustawa Herlinga-Grudzińskiego z 1983 r. Perspektywa francuska i włoska

From the beginning of the 1830s, mass emigration from Poland, not occurring on such a scale before, was noted, mainly for political reasons (especially after the defeats of the November and January uprisings). The emigration trend continued throughout practically the entire 20th century. It entered the history of Poles, especially the war and post-war period. The coming to power of the communists generated many problems. For political reasons, many dissidents sought freedom outside enslaved Poland. Many of them voluntarily and also under the compulsion of the then “people’s” government. There were two main centers of the political and cultural life of the Polish diaspora – in London and Paris. The Literary Institute, with its founder Jerzy Giedroyc and collaborator Gustaw Herling-Grudziński, played a significant role in the post-war period. Both, despite having different experiences and visions of a free and independent Poland, unanimously saw emigration as a specific form of struggle against the communist regime in Poland. They saw help and weapons in this struggle in the spoken and written word, through which they influenced both the Polish diaspora in many countries and their compatriots in Poland, which was subjugated by communists. They noticed the entire complexity of the problems faced by Polish emigrants, especially those arriving abroad at the beginning of the 1980s. Their accurate diagnoses and advice were not always accepted by the Polish diaspora. The interviews with them in a retrospective form reflect the atmosphere and spirit of the difficult and complex reality of that time.

Depression is a major societal issue. However, depression can be hard to self-diagnose, and people suffering from depression often hesitate to consult with professionals. We discuss the design and initial testings of our prototype application that performs depression detection using multi-modal information such as questionnaires, speech, and face landmarks. The application has an animated avatar ask questions concerning the users’ well-being. To perform screening, we opt for a 2-stage method which first predicts individual HAM-D ratings for better explainability, which may help facilitate the referral process to medical professionals if required. Initial results show that our system archives 0.85 Marco-F1 for the depression detection task.
AdSMOTE: A Technique for “High Proportion” Audio Augmentation
Authors: Jayathunge Kavisha , Yang Xiaosong , Southern Richard
Published: November 2023

Data augmentation is a practice that is widely used in the fields of machine and deep learning. It is used primarily for its effectiveness in reducing the generalisation gap between training and validation, as well as to artificially increase in available training data points. This is particularly relevant to audio datasets, which are usually smaller and suffer from imbalanced classes in some applications. This work presents adSMOTE (audio SMOTE), a novel sampling and augmentation strategy and also compares it to Specaugment, one of the most effective augmentation strategies for audio data. We show that our method outperforms the latter by a considerable margin when the proportion of synthetic training samples is high. We also provide source code for the complete algorithm, which can easily be integrated into an existing model, enabling the rapid development of augmentation frameworks.
EXPERIMENTAL AND NUMERICAL STUDY ON SOLAR ENERGY STORAGE IN BLACK-COVERED SUNSPACE USING WATER-FILLED TIN CANS
Authors: Afshari Faraz , Mandev Emre , Muratçobanoğlu Burak , Çelik Ali , Ceviz Mehmet Akif
Published: November 2023

In this study, the aim was to store solar energy in a sunspace room for energy savings in cold regions by using water-filled tin cans. The energy collected in the water during the sunbathing hours is transferred to the environment in the evening when the ambient air temperature suddenly drops. Additionally, the walls were covered with black material in the sunspace area to absorb maximum solar energy and then the heating performance was evaluated. In addition to experimental studies, ANSYS Fluent software (2022 R1 version) as a computational fluid dynamics (CFD) program has been used to simulate the sunspace domain in analyses. According to the obtained results, while there was a sudden drop in temperature in the ambient air after sunset, it was observed that the water temperatures in the tin cans decreased more slowly. This indicates that heat transfer from the tin cans to the ambient air occurs during the night. In addition, the effect of black surface application was shown and the differences between indoor and outdoor temperatures were evaluated. While the average temperature difference between the indoor and outdoor environment during the sunshine period without the black surface was 4.67°C, this difference increased to 9.53°C when the black surface was applied. The highest energy efficiency was achieved with the usage of the black surface, reaching a notable 58.2%.
Parasite composition of a raccoon transported to Iceland confirm its American origin
Authors: Skírnisson Karl
Published: November 2023

In 2018, a live raccoon was detected by a mink hunting dog in a burrow on the coast close to Keflavík International Airport in Iceland and subsequently shot. Dissection confirmed this non-native vagrant to be a subadult, immature female. Presence of some subcutan and kidney fat reserves suggested transportation to Iceland as a stowaway hiding in goods in an aeroplane - rather than having been locked up starving for weeks in a container on a freight ship. Raccoons are native in the Nearctic but were released in Europe in the last century. Parasitological examinations of the raccoon in Iceland revealed the presence of at least 13 parasite species. Five of them are common in American raccoon populations (Eimeria nuttally, Capillaria procyonis, C. putori, Molineus barbatus, Placoconus lotoris) but do not occur in European conspecifics. This confirms the American origin of the animal.

El imperativo de la agricultura hoy: cuidar la tierra
Authors: Tobasura Acuña Isaías , Obando Moncayo Franco H.
Published: November 2023

Desde que los humanos adquirieron conciencia de sus actos han generado relaciones de diverso orden con la tierra y sus habitantes. Con la emergencia de la agricultura, la tierra, de ser un bien libre y disponible para todas las criaturas vivientes, pasó a ser apropiado por los seres humanos para satisfacer necesidades. La tierra adquirió un valor utilitario, para producir alimentos y materias primas, y generar renta y poder político. No obstante, para los campesinos y pueblos indígenas, la tierra, además ha tenido y aún tiene un valor afectivo y sagrado. En esta lógica, la agricultura se constituye en vínculo de los seres humanos con la tierra, que conlleva un imperativo ético: cuidar la tierra, en tanto que esta es uno más de los sujetos de la comunidad ética. En este orden de ideas, este artículo discute el cuidado de la tierra como imperativo ético de la agricultura. Para ello, se analizan y discuten visiones de preservacionistas con visiones técnico-científicas de conservación de suelos.

Published: November 2023

El artículo presenta un análisis de las relaciones presentes entre capacidades humanas, educación en ciencias y contexto rural, en las producciones académicas publicadas entre enero de 2010 y enero de 2021. Constituye un resultado parcial en el proceso de construcción del proyecto de investigación doctoral del primer autor, titulado Capacidades humanas, educación en ciencias y ciudadanía ambiental en un contexto educativo escolar rural. Tiene como objetivo analizar cómo se ha articulado en algunas producciones académicas el tema de capacidades humanas con la educación en ciencias en el contexto rural. Así, inicia con un análisis documental de seis bases de datos: Education Resources Information Center, Education Research Complete, Academic Search Premier, Fuente Académica Plus, SciELO y el catálogo en línea del Centro Virtual de Memoria en Educación y Pedagogía, y continúa con un análisis de contenido para caracterizar cada una de las categorías. Los resultados del análisis dan cuenta de algunas limitaciones frente a la presencia de publicaciones que integren capacidades humanas, educación en ciencias y contexto rural. Además, se evidencian diferencias considerables entre la noción de capacidades y competencias y, por tanto, en la forma en como las capacidades son tipificadas desde cada uno de los artículos revisados según el énfasis.

Emergency Powers and Human Rights Derogations under the Constitution of Lesotho
Authors: 'Nyane Hoolo
Published: November 2023

Constitutions worldwide occasionally reach moments of public emergency when deviation from the ordinary normative framework is inevitable. To regulate the exercise of public power even during such moments, constitutions have provisions for emergencies and derogation from the normative frameworks. The Constitution of Lesotho is no exception. Section 21, read with section 23, provides both procedural and substantive requirements for the use of emergency powers and derogation from human rights. This constitutional framework exists alongside other pieces of legislation, such as the Public Health Order of 1970, the Emergency Powers Order of 1988 and the Disaster Management Act of 1997. These pieces of legislation, except the Disaster Management Act, predate the Constitution. Hence, they are not in harmony with the Constitution. The two recent incidences of using emergency powers – the 2020 coronavirus-induced state of emergency and the 2022 recall of parliament state of emergency. These two incidences laid bare two problems relating to the emergency powers regime in Lesotho. Firstly, there is no harmony between the Constitution and pieces of legislation relevant to the use of emergency powers. Secondly, the jurisprudence of the superior courts on the subject is still underdeveloped. The purpose of this article is to critically analyse the constitutional and legislative framework for exercising emergency powers and human rights derogation in Lesotho.
“Não Tenho as Condições”: Como os Jornalistas de Televisão e Rádio Avaliam a Qualidade do Jornalismo em Portugal
Authors: Silva Marta Santos
Published: November 2023

Estudar a qualidade do jornalismo em Portugal manifesta-se como relevante perante uma paisagem empresarial em crise financeira e redações cada vez mais pequenas com condições de trabalho precárias. Neste contexto, como é que os jornalistas portugueses de televisão e de rádio avaliam a qualidade do jornalismo praticado em Portugal e as condições que têm para o produzir? Através de entrevistas semiestruturadas a 11 jornalistas de rádio e de televisão em Portugal, procuramos responder a duas perguntas de investigação: (a) como é que os jornalistas de televisão e de rádio definem o jornalismo de qualidade?; e (b) como é que os jornalistas de televisão e de rádio avaliam a qualidade do jornalismo produzido em Portugal? Os entrevistados destacam a importância de seguir as regras deontológicas da profissão, de manter o rigor e a isenção e também outros tipos de características mais formais como, por exemplo, a qualidade da escrita ou a capacidade de cativar a audiência. Quanto às condições necessárias para praticar bom jornalismo, sobressai a importância do tempo e da estabilidade laboral, sobre as quais os entrevistados concordam estarem em escassez. Embora não sejam unânimes na sua avaliação da qualidade do jornalismo televisivo e radiofónico em Portugal — mesmo os mais positivos têm críticas a fazer —, a maior parte dos jornalistas entrevistados considera que as suas condições de trabalho para produzir bom jornalismo ficam aquém do desejado.
A study to evaluate adolescent girls\' practises and understanding of menstruation and menstrual hygiene
Authors: Mishra Pooja , Kumari Manisha
Published: November 2023

Menarche, which is connected to pubertal changes and the start of the ability to procreate, is a marker of femininity for adolescent females in Patna, Bihar. A growth surge and gonadal development take place during this time. preserving a healthy reproductive system is essential for preserving physical health and overall wellbeing. Menstrual hygiene plays a key part in this process. Therefore, it is crucial to spread information about menstruation and associated hygiene starting in adolescence in order to encourage safe practises and lessen the stress that millions of women experience.

We recruited 192 Patna-based teenage females from 9th to 12th grades using total enumeration sampling. We received written informed permission from parents and verbal consent from girls before starting the study. The Institute Ethics Committee also approved us. Data collecting resolved participant questions.

Out of the 192 females polled, around half of them showed signs of menstrual hygiene knowledge and admitted to using sanitary napkins. Additionally, 40.1% of the girls were aware of the signs and symptoms of poor menstrual hygiene.

This study suggests a menstruation and hygiene teaching programme for teenage females in Patna, Bihar. This programme would encourage good menstruation habits in young girls, improving reproductive health and well-being.
Unilateral supernumerary axillary breast secreting milk: A case report
Authors: Gupta Bhavana , Gupta Yajat
Published: November 2023

Accessory breast tissue or ectopic breast tissue or supernumerary breast tissue is an aberration of normal breast development. It is known to be rare entity which occurs in 0.4 - 6% of women anywhere along the embyologic mammary streak or milk line but more common in axilla. Accessory breast cancer is a rare entity with incidence of around 0.2 - 0.6 %. Routine mammography can miss accessory breast tissue. It is generally bilateral may be unilateral occasionally. General lack of awareness of accessory breast cancer among clinicians has potentially dangerous implications.

Knowledge about Accessory breast tissue has important implications for the patient care. If accessory breast tissue is not recognised, then a normal variant may be misdiagnosed as an abnormal lesion like lipoma, lymphadenopathy, sebaceous cyst, vascular malformation and malignancy. Also if surgical treatment is required it needs appropriate operative and post operative management.

Askin tumor is an uncommon malignant neoplasm of a neuroectodermic origin that arises from the soft tissues of the thoracopulmonary wall. Defined histologically by malignant small round cell tumor and immunohistochemistry positive for CD99. The lack of clinical guides that establish a standardized management contributes to its poor prognosis and short overall survival.
Acquisition of vocabulary in a foreign language classroom: the case of FFL in the minor of French at Qatar University
Authors: Alrabadi Elie , Harb Hiba
Published: November 2023

The objective of this research is to highlight the importance of vocabulary acquisition and lexical competence in the development of communicative competence among foreign language learners (FL). To achieve this goal, we have discussed the place occupied by vocabulary in the different methodologies of teaching / learning foreign languages, and we have defined the concept of lexicon and that of vocabulary. We have insisted on lexical competence and the different knowledge associated with it. We then identified our research context and analyzed certain difficulties encountered by our students in acquiring vocabulary in French as a Foreign Language (FFL). We ended up offering a number of activities to develop vocabulary acquisition in FFL classes. This research has therefore allowed us to observe that the acquisition of vocabulary remains a difficult task, especially in exolingual situations where FL is not used outside the classroom.
On payday lending: Identifying effective regulation measures
Authors: Campbell Steele , Kalenkoski Charlene , Lauderdale Mitzi
Published: November 2023

Many governments adopt regulations designed to prevent consumers from participating in specific financial markets or to limit the negative externalities of such markets. However, relatively little effort has been put into determining the efficacy of such regulatory measures. In many cases, effectively comparing these regulatory measures is limited by variations in preferences and cultures across nationalities. However, the United States may represent a unique situation where preferences and cultures are more homogenous across state lines than across international boundaries. As such, a comparison of the efficacy of these laws may yield a better understanding of which measures prove more effective than others. One such financial market that has received such attention is the payday lending industry, which is part of the broader subprime credit market. In the United States, each individual state has its own laws regarding subprime lending. The analysis in this paper finds that while some legal regimes have a relationship to positive or negative outcomes among consumers, others seem to have no relationship at all.
A 21. század világválságainak gazdasági hatásai Magyarországon
Authors: Káposzta József , Pongrácz Zsófia , Daróczi Miklós
Published: November 2023

A gazdasági válságok a kapitalista piacgazdaság velejárói, így elmondható, hogy a kialakulási körülmények is rendszerint közel, s távol azonosak. Egyes országok gazdasága olykor recesszióba fordul, ilyenkor a konjunktúrával ellentétben a nemzetgazdasági eredmények csökkenésével a GDP mértéke is csökken. A recesszióra számos tényező hatással van, ilyen például a munkaerő piac, a foglalkoztatottság, hitelkamatok, valamint a monetáris politika egyéb eszközei. Az általunk elemzett világválságok hatásai között tanulmányunkban is keressünk az összefüggéseket, ugyanis hatásaik alapján mindegyik érintette a jövedelmeket, a foglalkoztatottságot, az inflációt is. A válságok hatására romlanak az ipari teljesítmények, csökkennek a beruházások értékei és ezek összefüggésében a fogyasztás mértéke is. Megállapítható, hogy a gazdasági válságok a kapitalista piacgazdaság velejárói, így a kialakulási körülmények is rendszerint közel azonosak, így elemzésük, kapcsolati rendszerük vizsgálata lehetőséget adhat az ismétlődő gazdasági válságok negatív hatásainak mérsékléséhez. Tanulmányunkban a 2008-ban indult világgazdasági pénzügyi válság és a 2019-ben indult Covid-19 által okozott gazdasági recesszió kapcsolatát vizsgáltuk és kerestük hatásaik összefüggéseit.
A felnőtteknek szóló képzések jellegének, ezen belül az álláskeresőknek szóló képzések céljának és finanszírozásának változása hazánkban 2010 és 2020 között
Authors: Szabóné Tóth Éva
Published: November 2023

A felnőttképzéssel szemben támasztott alapvető elvárás lenne, hogy azonnal reflektáljon a munkaerőpiac valódi igényeire és a képzési kínálatot ne az éppen rendelkezésre álló kapacitások és erőforrások vezéreljék. Az álláskeresőknek szóló képzések célja, hogy az álláskeresők egy új piacképes szakma elsajátításával minél hamarabb visszakerüljenek az aktív munkaerőpiacra. Szekunder forrásból származó statisztikai adatsorok elemzésével az volt a célkitűzésem, hogy feltárjam a változó igényekhez való alkalmazkodás folyamatának jellegzetességeit. A képzések típusai közötti arányváltozások mellett elemeztem azok finanszírozási hátterét is a 2010 és 2020 közötti vizsgálati időszakban. Azt követően, hogy 2011-ig hazai forrásból valósult meg több képzés, a későbbiekben egyre csökkent annak szerepe és az EU-s forrásból finanszírozott képzések váltak dominánssá. Az állam által elismert OKJ szakképesítést adó képzésekre beiratkozott tanulók száma kisebb hullámvölgyek mellett növekvő tendenciát mutatott, az informatikai képzések esetében 2017 után markáns növekedés mutatkozott, a nyelvi képzések összesített létszáma azonban 2014 után visszaesett.
The Reductive Synthesis of Silver Nanoparticles Using Sodium Citrate and Their Potential Medical Uses in Skin Diseases
Authors: Tareq Mahdi Mustafa
Published: November 2023

This study investigates how silver nanoparticles develop and how they might be used as an antibacterial agent to prevent and treat wound infections. The reduction procedure was used to create silver nanoparticles—sodium citrate functions as both a lowering and a stabilizing agent. The properties of the liquid silver nanoparticles were then examined using a UV-Vis Spectrometer, a Particle Size Analyzer (PSA), and a Transmission Electron Microscope (TEM). UV-Vis studies show that nanoparticles produced with 1% sodium citrate are the most stable. PSA and XRD analyses reveal that the smallest silver nanoparticles are approximately 8 nm, with an average size of approximately 30.2nm. According to TEM examination, silver nanoparticles with an FCC crystal structure. In studies, pathogenic microorganisms such as E. coli, Bacillus subtilis, and Staphylococcus aureus were employed to assess how successfully the washing process inhibited bacterial growth. The quantitative research demonstrates that increasing the soaking period to 36 hours kills all germs and results in a 100% reduction. The best time to soak wound therapy linen in synthetic silver nanoparticles was 36 hours.
