Published: September 2023

Giriş: Amacımız Atmosferik Soğuk Plazma ile muamele edilmiş PBS'nin Gram pozitif ve Gram negatif çoklu ilaca dirençli bakterilere karşı etkinliğini araştırmaktır.

Gereç ve Yöntemler: Toplam 50 karbapenem dirençli Klebsiella pneumoniae ve 10 vankomisin dirençli Enterococcus faecium suşu çalışmaya dahil edilmiştir. 100 µl bakteri süspansiyonu (107 CFU/ml) üzerine 100 µl (1/2), 300 µl (3/4), 700 µl (7/8), 1500 µl (15/16), 3100 µl (31/32), 6300 µl ACP ile muamele edilmiş PBS eklenmiştir. Süspansiyon pipetlendikten sonra oda sıcaklığında 30 dakika inkübe edilmiş, koyun kanlı agara ekilmiş ve 37°C'de bir gece (16-18 saat) inkübe edilmiştir.

Bulgular: Çalışılan tüm suşlar ASP ile muamele edilmiş PBS çözeltisi tarafından inhibe edilmiştir. Verilen dilüsyonlar bakteri çoğalmasının tamamen inhibe olduğu dilüsyonlardır. K. pneumoniae suşlarının 45'i ACP ile muamele edilmiş PBS çözeltisi ile 3/4 konsantrasyonda tamamen inhibe olurken, K. pneumoniae suşlarının 5'i ACP ile muamele edilmiş PBS çözeltisi ile 7/8 konsantrasyonda tamamen inhibe olmuştur. Vankomisine dirençli E. faecium suşları, K. pneumonia suşlarına göre daha yüksek miktarlarda plazma ile inhibe edilmiştir. E. faecium suşlarından üçü (15/16), E. faecium suşlarından üçü (31/32), E. faecium suşlarından dördü (63/64) ACP ile muamele edilmiş PBS solüsyonu tarafından tamamen inhibe edilmiştir.

Sonuç: ACP ile muamele edilmiş PBS çözeltisinin önemli antibiyotiklere dirençli hem Gram-pozitif hem de Gram-negatif bakterilere karşı etkili olduğu bulunmuştur. Seçilen Gram-negatif ve Gram-pozitif bakterilerde inaktivasyon için gereken ASP ile muamele edilmiş PBS konsantrasyonunda farklılıklar gözlenmiştir. Bununla birlikte, hem Gram-negatif hem de Gram-pozitif enfeksiyonlarda mevcut tedavi seçenekleri gün geçtikçe azaldığı için bu yöntem umut vericidir. ASP ile muamele edilmiş PBS sıvılarının bir tedavi yöntemi olarak kullanılması için ileri çalışmalara ihtiyaç vardır.

Published: September 2023

INTRODUÇÃO: A COVID-19 é uma virose zoonótica que teve origem em Wuhan em dezembro de 2019. O sintoma inicial foi o aparecimento de severos casos de pneumonia repentinos. Contudo, a infecção pelo SARS-CoV-2 resulta, igualmente, em múltiplos acometimentos patológicos extrapulmonares, implicando consequências nos mais variados sistemas biológicos. OBJETIVOS: Tendo em vista tal abrangência da doença e a vertiginosa disseminação internacional, implicando danos tanto humanos como socioeconômicos, atrelados à expressiva abrangência no sistema do corpo humano; este estudo visou elaborar uma análise bibliométrica que avalie os sistemas do corpo humano afetados pela doença por meio de busca de artigos mais citados na literatura. MATERIAL E MÉTODOS: Compilou-se, a partir da base de dados da Web of Science (WoS) Core Collection, os artigos mais citados e selecionados por palavras-chave no idioma inglês que relatassem os acometimentos da COVID-19 nos sistemas do corpo humano. A partir disso, foram investigados os termos referentes a cada sistema em associação com os seus respectivos órgãos a partir de uma análise bibliométrica, excluindo aqueles que não estavam correlacionados com o contexto da COVID-19. Por fim, foram elaborados gráficos para se estabelecer, quantitativamente, a ocorrência do acometimento da doença em cada sistema afetado. RESULTADOS: Foi elaborada uma relação quantitativa sistemática pela técnica da bibliometria por meio do levantamento destes termos, que resultou em uma disposição, selecionada pelas quantidades de citações válidas, em ordem decrescente: o respiratório (24,20%), cardiovascular (22,92%), nervoso/sensorial (15,53%), urinário (11,29%), digestório (10,52%), linfático/imune (8,13%), locomotor (2,89%), endócrino (2,38%), tegumentar (1,62%) e, o sistema reprodutivo (0,47%). CONCLUSÃO: Dentre os sistemas que compõem o sistema orgânico humano, seu grau de acometimento por COVID-19, em ordem decrescente, corresponde aos sistemas respiratórios, cardiovasculares, nervosos/sensoriais, urinários, digestórios, linfáticos/imunes, locomotores, endócrinos, tegumentares e reprodutivos. Cada um destes sistemas detém peculiaridades relacionadas à fisiopatologia e à sintomatologia da infecção por COVID-19, que, deste modo, se apresenta como uma doença multissistêmica que afeta, de modo distinto, cada um dos sistemas do corpo humano.

The term transsexuality continues to be hotly debated in the literature and for many has become a scientific void. We sought to analyze the scientific production on transsexuality in Scopus, 2010-2022. Under a retrospective descriptive design, 624 articles were studied. It was found that 85.58% were research articles. Brazil has more research on the subject (41.83%); institutions in Brazil, Peru and Argentina have the highest production, and AIDS and Behavior and Plos One are the journals with the largest publications. The authors belong to Brazilian and Peruvian institutions. Research on transsexuality is minimal, so further research is needed.

Published: September 2023

The aim of this research is to identify the factors impacting customer satisfaction, focusing on customer perceptions within one of the country's most prominent delivery companies, specifically centered in the city of Chiclayo, Peru. The study utilizes the SERVPERF model, which gauges customer perceptions across five dimensions: reliability, responsiveness, security, empathy, and tangibility. Interviews were conducted with the manager and several delivery drivers in the city to comprehend operational processes. To gather unbiased customer opinions, a survey was administered to 196 customers. The results indicate that customers assess the company's service quality as average. Despite the elevated demand, customers display a relatively low level of contentment with the service provided. Furthermore, the research explores the extent of customer satisfaction. Through Pearson's correlation analysis, it was ascertained that the dimensions exerting influence on satisfaction encompass reliability, security, and empathy. The study also establishes that the degree of satisfaction averages out and is intrinsically tied to the quality of service.

The Comparative of Arbitration Performance and Public Court on Settlement of Civil Disputes in Indonesia
Authors: Abdullah Iqbal Alan
Published: September 2023

The purpose of this study is to describe the comparison of dispute resolution mechanisms by arbitration and dispute resolution through general courts. This study uses normative juridical, referring to legal norms which include laws and regulations, court decisions and applicable legal rules. Furthermore, this research will answer legal issues regarding dispute resolution through arbitration. Normative legal research is "legal research conducted by examining literature (secondary data). The results of the study indicate that there are two choices of arbitral institutions to resolve disputes, namely arbitration and general courts. Comparison of dispute resolution mechanisms between arbitration and institutional arbitration is that arbitration has the freedom of the parties to determine the arbitrator, guarantees the confidentiality of the parties because dispute resolution is carried out in private, the parties can determine the place of arbitration, choice of law in dispute resolution, and the dispute resolution process is faster, namely can be completed in no more than 180 days. While settlement through a general court requires a relatively long time, is open to the public, and is confrontational in nature, all decisions are final and binding. However, for arbitration, the recognition and implementation of the decision must still be registered with the district court. Weaknesses of arbitration are the emergence of suspicion of each party about the closeness of the arbitrator, given the current sophistication of technology, so that the number of dispute resolution through arbitration in Indonesia is very small. Society prefers litigation over non-litigation.

Authors: Alvarado-Silva Carlos Alexis , Gastiaburú-Morales Silvia Yvone , Gaytan-Reyna Karina Liliana , Gaytan-Reyna Sassy Emperatriz , Silva Fernando De Azevedo
Published: September 2023

Using the 3D printing method as an engineering teaching tool has been intensifying and implemented throughout all the courses of the engineering career and even in research departments, this means that it not only fulfills the functions for those that were originally designed (manufacturing of parts) but as a support for the acquisition of other important skills in future engineers. The research has a quantitative approach, experimental design with a control and experimental group of 35 and 37 students respectively. For its execution, a pre-test and post-test have been used as instruments, which were applied to students of a Technical Drawing subject of the career of Mechanical-Electrical Engineering. The findings reveal that the proposed teaching strategy using 3D printed elements significantly improves the level of abstraction for the generation of orthogonal projections. After the experiment, the control group showed an improvement in average grades of 20.3%, this indicates that the application of traditional teaching improves the level of abstraction. In the case of the experimental group, a higher average of the grades was obtained with a 30.8% improvement, which means that the students felt more comfortable with the proposed teaching strategy. On the other hand, the proposal was well received by the students who participated in the session, as they stated through the satisfaction survey that they were 90% between satisfied and very satisfied.

The Impact Of The War Between Russia and Ukraine Upshot Policy Change And Inflation – A Case Based Analysis
Authors: - Rajib Kumar Sanyal
Published: September 2023

The myriad consequences of a global energy reboot means that there may be some positive developments, too. However, with so much in a state of flux, it is difficult to predict with much certainty. Russia’s invasion of Ukraine in February 2022 has had a profound effect on global energy markets. Price volatility, supply shortages, security issues and economic uncertainty have contributed to what the International Energy Agency (IEA) is calling the first truly global energy crisis, with impacts that will be felt for years to come. Coupled with the impact of the global pandemic, the energy crisis means 70 million people who recently gained access to electricity can no longer afford it. And 100 million people may no longer be able to make food with clean fuels.

Dietary Habits and Gut Microbiome: An Influence on Gut Brain Axis
Authors: Yadav Gyan Vandana
Published: September 2023

Intimate connections between the brain and the human gut provide a system of neurohumoral communication that may exist both ways. The link between the GI tract and the brain is so effectively-established that the central nervous system's health is always correlated with how well the gut performs. The majority of research on the gut-brain axis focuses on how mental health influences how effectively the GI system works. Recent research, however, suggests that the gut flora communicates with the brain via this axis to govern phenotypic alterations in the brain and behavior. The involvement of the microbes found in the stomach in the gut-brain axis is a significant breakthrough in identifying precise differences of the microbiota in the gut microbial constitution. However, because to the large number of intestinal bacteria and the difficulties associated with cultivating gut microbes, identifying the microbes that form the gut microbiota has emerged as the most serious scientific issue today. The current methods for identifying the microorganisms that comprise the gut microbiota rely heavily on emerging technologies and omics research techniques. In this article, we focus on the relationship between an individual's gut microbiota and the link between the gut and the brain, and we also consider the benefits and drawbacks of the present technology with high throughput for identifying the bacteria that together make up the gut microbiota, in order to further comprehend the role of gut microbiota in the gut-brain axis. The relationship between the gut and the brain is the topic of this review. The narrative overview explores the relevant scientific literature to provide a comprehensive account of this extensive concern.

A Conceptual-Methodological Framework to Investigate the Mathematical Practices with DGS in Secondary Students
Authors: Carlos Roberto Pérez Medina
Published: September 2023

This contribution presents a conceptual-methodological framework to study mathematical practices from the instrumental aspect inherent to the activity of learning instrumented with Dynamic Geometry Systems (DGS) of a student at a secondary school [In Argentina, secondary education is compulsory training for young people from 12 to 17 years old]. This framework has a conceptualization of the mathematical practice with Dynamic Geometry Systems and a method to favour its operationalization. The framework has been built from diverse theoretical perspectives, in the environment of ergonomic approach of instrumental approximation in a didactical perspective and a qualitative methodology. The method to define the practice indicators that allow to identify it in the field is illustrated with parts of the results of the research in which it originated. One important implication of the framework is that it values, from a didactical perspective, the instrumental character of the activity of using Dynamic Geometry Systems in students that learn geometry, through a concrete definition of mathematical practices with Dynamic Geometry Systems and the operationalization of its analysis for a geometry content. This framework is an original contribution that refers to the knowledge about the existence of mathematical practices with Dynamic Geometry Systems about the content of school geometry.

Authors: Agordah Faustina Emefa , Jacqueline Kisato , Kaindi Isika Juliet
Published: September 2023

The art of millinery has been in decline despite its significant contribution to the performance of fashion design students in the industry. This study investigated the prerequisite skills of HND fashion design students in the acquisition of millinery art skills in technical universities in Ghana. The sample consisted of 249 HND level 200 students and 31 millinery art lecturers from five selected Technical Universities. The study employed multistage and stratified sampling methods to gather data from the participants. Data was gathered through the utilisation of an interest inventory and a semi-structured interview guide. The study data was analysed using frequency tables to assess the relationship between prerequisite skills and the acquisition of millinery art skills. A Chi-square Test of Independence was conducted to examine the association between the millinery art skills acquired and practised in the participants’ institutions. The findings revealed that the students possessed the necessary skills and exhibited a genuine interest in millinery art before enrolling in the Fashion Design program. However, their interest waned following their instruction in millinery art at different educational institutions. The null hypothesis indicating that there is no relationship between the institution attended and the millinery art skills acquired and practised by students, was rejected based on the statistical analysis. The chi-square value was 135.42, with 4 degrees of freedom and a sample size of 249. The p-value was found to be 0.000, which is less than the significance level of 0.05. The study suggests that Technical Universities should assist lecturers in obtaining industrial training in millinery art. This will improve the acquisition of millinery art skills.
Pneumokokinės infekcijos epidemiologinė analizė Kauno apskrityje 2022 m.
Authors: Knapkė Gintarė
Published: September 2023

Pneumokokinė infekcija – tai grupė skirtingai kliniškai pasireiškiančių ligų, kurias sukelia bakterijos Streptococcus pneumoniae, paprastai vadinamos pneumokokais. Europos ligų prevencijos ir kontrolės centras (toliau – ECDC) informuoja, kad pneumokokinės infekcijos ir invazinės pneumokokinės ligos, tokios kaip bakteriemija, sepsis, meningitas ir osteomielitas, yra pagrindinės sergamumo ir mirtingumo nuo užkrečiamųjų ligų priežastys Europoje bei visame pasaulyje, kuomet didžiausia šių ligų našta tenka vaikams ir vyresnio amžiaus žmonėms. ECDC duomenimis, Europos Sąjungos ir Europos ekonominės erdvės (toliau – ES ir EEE) šalyse 2021 m. nustatyti 8 962 susirgimai pneumokokine infekcija, iš jų 25 nustatyti Lietuvoje. Lyties atžvilgiu 58,7 proc. visų susirgimų pneumokokine infekcija ES ir EEE šalyse priklausė vyrams, 41,3 proc. sudarė moterys. Be to, ES ir EEE šalys 2021 m. pranešė apie 411 mirties atvejų nuo pneumokokinės infekcijos, iš jų trys užfiksuoti Lietuvoje. Nustatyta, kad kas antras (59,37 proc.) asmuo, miręs nuo pneumokokinės infekcijos ES ir EEE šalyse, buvo vyresnis nei 65 metų amžiaus. Lietuvoje 2021 m. visi nuo pneumokokinės infekcijos mirę asmenys buvo 65 metų amžiaus ir vyresni. Akivaizdu, kad daugelio ligų ir mirties atvejų ne tik nuo pneumokokinės infekcijos, bet ir nuo kitų vakcinomis valdomų užkrečiamųjų ligų, būtų galima išvengti, taikant vieną veiksmingiausių būdų užkrečiamųjų ligų prevencijai ir kontrolei – visuotinę imunizaciją.

For this reason, manufacturers must be able to regulate machining processes to ensure improved performance and service life of engineering components. This research work presents a study on the optimization of machining parameters for mild steel using artificial neural networks (ANNs). The focus is on developing an effective and efficient machining technique for mild steel by leveraging the capabilities of ANNs to predict optimal machining parameters. To bridge the gap between laboratory figures, model-simulated values, and real-world application, experiments were conducted to obtain data used in the research analysis. Levenberg-Marquardt method were utilized to train the ANNs, with input factors like depth of cut, bearing clearance, cutting speed, and feed rate considered, while the surface roughness of the cut, normalized within 0 to 1 range. A statistical measure of the surface roughness predicted using indicated MAPE value of 0.002% while the correlation coefficient (R) was 0.99995. The results showed that ANNs are a viable machining parameter optimization method and can improve product quality, while providing significant economic and production benefits.

Published: September 2023

The study examined climate change's effect on cocoa production in the central agricultural zone of Cross River State, Nigeria. It specifically investigated the socioeconomic characteristics of cocoa farmers and the effect of climate variables on cocoa production in the study area. Both primary and secondary data were used for the study. Primary data were collected from 240 respondents and analyzed using descriptive statistics and the Likert scale techniques, Regression and correlation analysis were used to analyse the secondary data collected. The results of the descriptive statistics revealed that cocoa production was carried out by both men and women with men taking the production lead at 65.8% as compared to 34.2% of the women. On age distribution, the study revealed people within the age bracket of 18-50 years majorly cultivate cocoa in the area. The educational level revealed that the farmers had some form of formal education with good farming experience of between 11-20 years in cocoa production. The farmers had family sizes ranging largely between 6-15 persons in a household. The result also showed that 40% of the respondents inherited their farm holdings while 27.5%, 21.7%, and 10.8% of the respondents hired, purchased and rented their farm holdings respectively. The results of the multiple regression analysis revealed that about 78% of the climate variables influenced cocoa output in the area. It indicated that maximum temperature (Χ1), relative humidity (Χ4), wind (Χ6), and evaporation (Χ7) had an inverse relationship with cocoa output, whereas minimum temperature (Χ2), rainfall (Χ3), and sunshine hours (Χ5) had a direct relationship with cocoa output in the study area. The correlation analysis revealed that maximum temperature (Χ1), relative humidity (Χ4), and wind (Χ6) are negatively correlated with cocoa output while minimum temperature (Χ2), rainfall (Χ3), sunshine hours (Χ5) and evaporation (Χ7) are positively correlated with cocoa output in the study area. The most common strategies adopted by cocoa farmers to mitigate the effect of climate variables on cocoa production were the planting of cocoa-resistant varieties and intercropping cocoa with some tree crops to foretell bad weather conditions.

In this paper, the problem of bending of a multilayered rod by transverse loads in the presence of zones of elastic and nonlinear-inelastic deformation is considered, the retios are obtained to determine the boundary between the elastic and nonlinear-inelastic areas of deformation of the rod. Various cases of the position of the specified boundary between areas are considered, depending on external loads. The expressions for ultimate loads are given for each of the characteristic cases of the location of these boundaries: the first (deformation reaches the limit elastic value) and the second (deformation reaches the value of pre-fracture deformation).

The positive effects of plants, including stinging nettle (Urtica dioica L.) were reported by numerous researchers (1) as well as changes in the chemical composition of the plant due to heavy metal pollution (2, 3). This study aimed to compare the changes in body wight, total leukocyte numbers (TL) and delayed type hypersensitivity (DTH) in 28 days old chickens (n=12/group) injected subcutaneously twice (days 0 and 7), with 0.5 ml of alcoholic nettle extracts harvested from both unpolluted (group III) and polluted areas (group IV), against untreated (group I) and 700 alcohol treated (group II) controls. Blood was sampled three times, on days 0, 7 and 14, while the wattle test to a homologous lymphocyte suspension was performed on day 14 of the experiment.

There were no significant differences in weight gain/period between groups III (0.979 kg) and IV (0.967kg), against each other and controls (0.991 kg-group II and 1.029 kg - group I, respectively). As opposed to the slight changes of the TL in control groups, there was a constant increase in group III (from 15,400±3,421/mm3 to 17,125±4,231/mm3) and a decrease in group IV (17,611.1±2,401/mm3 to 17,166.7±2,522/mm3).

The wattle test results after 48 h were similar in groups I, II and IV, the differences ranging between 0.23 and 0.28 mm, while the unpolluted nettle extract diminished the DTH to a difference of 0.07 mm.

The polluted nettle extract induced the lowest weight gain and TL numbers, and increased the wattle reactivity when compared to the unpolluted one.
A New Insight into the Linear Theory of Magnetoacoustic Waves in the Homogeneous Flux Tubes with an Abrupt Boundary
Authors: Yelagandula Naga Varun
Published: September 2023

An important and interesting issue is brought to notice in the standard linear theory of the magnetoacoustic waves in the homogeneous magnetic flux tubes with an abrupt magnetic boundary, which are representative of the coronal, chromospheric, and photospheric loops of the solar atmosphere. It is shown that the dispersion relation given for the magnetoacoustic waves of such flux tubes by the linear standard theory is generally inapplicable because it does not take into account the electrodynamic boundary condition and the applicability is only restricted to the case β = 0, where β is the usual plasma parameter given by the ratio of the thermodynamic gas pressure to the magnetic pressure. This issue is then addressed, which gives us new insight into the standard linear theory of such modes, and a new dispersion relation is obtained, which is generally applicable i.e., for all β and would reduce to the earlier expression as a special case for β = 0. Finally a comparison is drawn between the dispersion curves described by the newly derived dispersion relation and its previous counterpart.
Toward an Optimal Reconstruction of the Shear Field with PDF-folding
Authors: Wang Haoran , Zhang Jun , Li Hekun , Liu Cong
Published: September 2023

Weak lensing provides a direct way of mapping the density distribution in the Universe. To reconstruct the density field from the shear catalog, an important step is to build the shear field from the shear catalog, which can be quite nontrivial due to the inhomogeneity of the background galaxy distribution and the shape noise. We propose the PDF-folding method as a statistically optimal way of reconstructing the shear field. It is an extention of the PDF-SYM method, which was previously designed for optimizing the stacked shear signal as well as the shear-shear correlation for the Fourier_Quad shear estimators. PDF-folding does not require smoothing kernels as in traditional methods, therefore it suffers less information loss on small scales and avoids possible biases due to the spatial variation in the shear on the scale of the kernel. We show with analytic reasoning as well as numerical examples that the new method can reach the optimal signal-to-noise ratio on the reconstructed shear map under general observing conditions, i.e., with inhomogeneous background densities or masks. We also show the performance of the new method on real data around foreground galaxy clusters.
