ABOUT CREATING OPEN-SOURCE 3D MODULAR VIEWER IN PYTHON
Authors: Sikic G , Prebeg P
Published: October 2022

During the development of the ShipExplorer suit of the programs, great attention was given to building the application, modularization, and code organization. During that period, successful cooperation with UNIZAG FSB was established, resulting in a new requirement that students with no real experience in SW development create new modules that will solve some specific problems.
After the ShipExplorer project was put on hold, it was decided to start a new project with similar objectives, that will fulfil UNIZAG FSB requirements from the start, and help save and use the huge knowledge base gained during the development of ShipExplorer. As a result, project, “3D Modular Viewer” was created.
In this paper, experience designing and implementing 3DM viewer will be presented, as well as problems that had to be solved. The choice of the programming language will be discussed, together with additional constraints resulting from that decision. Design decisions and implementation details will be reviewed, and the results will be compared with the original program, ShipExplorer.

Published: October 2022

In the shipping industry, changes in freight rates are extremely drastic. Therefore, shipping companies needs to develop a forecasting method for freight rates to achieve sustainable growth. Recently, the details of the movement data of each ship have been obtained through the development of an automatic identification system (AIS). Therefore, we developed a practical forecasting model that combines AIS and statistical data. In our previous study, we proposed a method to develop a forecasting model for freight rates by combining AIS and statistical data using deep learning. However, there are some
issues with the previous model. In this study, we analyzed the causes of deterioration in forecast accuracy from the perspective of the internal factors of the forecasting model. In addition, we developed a prediction system for demonstration tests and verified its applicability by comparing expert predictions.
Constituer, conserver et développer une collection vivante au Muséum (1793-1824)
Authors: Lippi Laurence
Published: October 2022

Si un lieu clos, tel un musée, un cabinet, préserve une collection publique ou privée d’objets, il en est un souvent négligé : le jardin botanique. André Thouin (1747-1824), jardinier en chef du Jardin royal, national en 1793, forme des jardiniers à la culture des plantes collectées lors d’expéditions ou près de Paris. Depuis la parution de l’ouvrage d’Y. Letouzey, les historiens évoquent Thouin comme le régisseur d’un jardin au cœur d’un réseau de botanistes, un expert dans la naturalisation de plantes utiles à l’économie. Cette contribution réintègre l’importance du jardinier dans la connaissance de l’histoire des collections et savoirs botaniques. À partir de l’étude des archives de la Bibliothèque centrale du Muséum (MNHN), des Archives nationales (AN) et des résultats d’un mémoire de master (2019, Centre Koyré), elle montre comment Thouin, pour servir les ambitions d’un intendant et celles d’une jeune République, instruit ses jardiniers à herboriser et à conserver les plantes dans le milieu artificiel du Jardin et des serres du Muséum.
O tamanho populacional das cidades importa? Uma análise econômico-financeira dos municípios do COREDE Fronteira Noroeste do Rio Grande do Sul
Authors: Brum Argemiro Luís , Baggio Daniel Knebel , Farias Maurício Galeazzi Medeiros de
Published: October 2022

O objetivo principal deste artigo é identificar, a partir da temática emancipações-desenvolvimento, se o processo de divisão dos municípios é fator relevante para o desenvolvimento das regiões. Faz-se uma reflexão sobre a situação fiscal e financeira dos territórios emancipados, que geralmente resulta em pequenos municípios, tomando-se como referência àqueles que compõem o COREDE Fronteira Noroeste gaúcho. Para esta pesquisa foram utilizados dados de órgãos oficiais, censitários e indicadores econômicos para, assim, auxiliar na análise, interpretação e caracterização da diferença entre os municípios da região escolhida. Conclui-se que boa parte das emancipações acaba gerando pequenos municípios com pouca população, fraca base tributária e decréscimo na quantidade de serviços prestados. Como consequência, esses pequenos municípios acabam dependendo, quase que exclusivamente, de transferências do governo central. Assim, não teria sentido criar novos municípios no interior do país, salvo exceções.

Published: October 2022

This study examined challenges and factors promoting resilience among 20 California family physicians (FPs) during the first six months of the COVID-19 pandemic. A subset of academic, community, and resident FPs who responded to an online survey also participated in a semi-structured interview that explored concerns, moral distress, burnout, resource needs, support systems, coping strategies, and motivation to continue caring for patients. Thematic analysis was used to identify common themes in participant interviews. Interviewees demonstrated adaptability, resilience, and grit (i.e., commitment to completing a valued goal in the face of setbacks and adversity) despite challenges disrupting patient care, fears for family and self, and frustration due to the politicization of the pandemic. Factors promoting well-being and perseverance included professional and personal support, strong coping skills, and focusing on the meaning derived from practicing medicine. A service orientation that permeates family medicine philosophy and values motivated practitioners to continue to provide patient care while dealing with overwhelming personal and structural challenges. FPs drew strength from their internal coping skills, core family medicine values, and external support, notwithstanding demoralizing effects of mixed messages and politicization of the pandemic. FPs demonstrated resilience and grit in the face of challenges created by the COVID-19 pandemic. Ensuring adequate resources to promote a physically and psychologically healthy workforce while increasing access to care for all patients is crucial to prepare for the next healthcare crisis.

Published: October 2022

Background and Objectives:

Over the last two decades, EUS-guided hepaticogastrostomy (EUS-HGS) has emerged as a therapeutic alternative for patients with biliary obstruction and failed ERCP. Percutaneous transhepatic biliary drainage (PTBD) as the gold standard is associated with relevant morbidity and need for re-intervention. The aim of our work was to evaluate in a phase II study the safety and efficacy profile of EUS-HGS. A PTBD arm was considered a control group.

Patients and Methods:

We conducted a prospective, randomized, noncomparative phase II study in three French tertiary centers involving patients with benign or malignant obstructive jaundice after failure of ERCP. Patients were randomized to either PTBD or EUS-HGS.

Results:

Fifty-six patients (mean age 64 years) have been included between 2011 and 2015. Twenty-one underwent PTBD and thirty-five were drained using EUS-HGS. An interim analysis after the inclusion of 41 patients revealed an unexpected high 30-day morbidity rate for PTBD (13 out of 21 patients), justifying to stop randomization and inclusion in this control arm in 2013. The primary objective was reached with 10 out of the 35 EUS-HGS patients (28.6%) having observed complications (90%-level bilateral exact binomial confidence interval [CI] [16.4%–43.6%], left-sided exact binomial test to the objectified 50% unacceptable rate P = 0.0083). Both methods achieved comparable technical success rate (TSR) and clinical success rate (CSR) (TSR: PTBD 100% vs. EUS-HGS 94.3%, P = 0.28; CSR: PTBD 66.7% vs. EUS-HGS 80%, P = 0.35). Long-term follow-up showed EUS-HGS patients being at lower risk for re-intervention (relative risk = 0.47, 95% CI [0.27–0.83]).

Conclusion:

In cases of ERCP failure, EUS-HGS is a valuable alternative for biliary drainage with a high TSR and CSR. PTBD is associated with an unacceptable 30-day morbidity rate, whereas EUS-HGS seems to have a decent safety profile, suggesting that it may be the treatment of choice in appropriately selected patients.

Authors: Diala Udochukwu Michael , Kanhu Patience Ungut , Shwe David Danjuma , Toma Bose Ozoiza
Published: October 2022

Background:

Hypothermia on admission in neonatal units is a well-recognized contributor of neonatal mortality and morbidity. This study aimed to identify risk factors for hypothermia on admission in a resource-poor setting which will help provide targeted preventive interventions.

Methods:

A retrospective cross-sectional descriptive study was conducted from July 1, 2020 to January 31, 2022. A total of 567 neonates were included in the study, data were collected from the unit electronic database. The axillary temperature of each neonate was measured using a digital thermometer at the point of admission. Bivariate and multiple logistic regressions were used to assess associated risk factors.

Results:

The prevalence of admission hypothermia (AH) in the study population was 42.4% with mild and moderate hypothermia accounting for 46.3% and 53.7%, respectively. Maternal ages 20–29 years (adjusted odds ratio [aOR] 0.28, 95% confidence interval [CI] 0.09–0.93) and 30–39 years (aOR 0.27, 95% CI 0.08–0.88) and primary education (aOR 0.44, 95% CI 0.21–0.92) were associated with reduced risk of AH. Age <24 h (aOR 3.61, 95% CI 1.70–7.66), gestational age 28–32 weeks (aOR 3.90, 95% CI 1.41–10.79) and 33–36 weeks (aOR 2.835, 95% CI 1.52–5.28), admission weight <2.5 kg (aOR 2.01, 95% CI 1.18–3.43), and cold season (aOR 1.85, 95% CI 1.06–3.14) were associated with increased risk of AH. Mortality in those with AH was 3 folds (crude odds ratio 3.38, 95% CI 1.6–6.82).

Conclusion:

Hypothermia on admission is common in neonates in resource-poor settings. Training of newborn care-providers in maintaining thermoneutral environment and temperature at delivery and postnatal periods will be a cost-effective intervention in reducing neonatal mortality.

Authors: Alshammari Sarhan , Alqashami Azzam , Alhumud Saleh , Aladadh Meshari , Alsaif Saif , Ali Kamal
Published: October 2022

Background:

Better understanding of the clinical characteristics of ABO hemolytic disease in neonates helps optimize care.

Objective:

To assess the morbidity associated with ABO incompatibility.

Materials and Methods:

Neonates with blood groups A or B born to mothers with blood group O were studied. Need for phototherapy (PT), intensive PT, intravenous immunoglobulin (IVIG) therapy, and packed red blood cell (PRBC) transfusions was studied.

Results:

The O–A group accounted for 57.2% and the O–B group 42.8%. Three-hundred and seventy-nine (46%) were Direct Coomb's test (DCT) positive. Need for PT and intensive PT was significantly higher in DCT-positive infants compared to DCT-negative infants (P < 0.001). DCT-positive infants required more PRBC transfusions (5.3% vs. 0.9%, P < 0.001) and IVIG therapy (6% vs. 0.2%, P < 0.001) compared to DCT-negative infants. Sixty percent of the blood group B infants were DCT positive compared to 35% of blood group A infants (P < 0.001). Need for PT (62% vs. 39%, P < 0.001), intensive PT (17% vs. 4%, P < 0.001), and IVIG therapy (5.4% vs. 0.8%, P < 0.001) was higher in infants with blood group B. TcB measured at median age of 12 h was predictive of the need for PT (area under the receiver operator characteristic [AUROC] =0.867) and intensive PT (AUROC = 0.917). The maximum reticulocyte percentage was predictive for both the need for IVIG therapy (AUROC = 0.978) and PRBC transfusion (AUROC = 0.863).

Conclusions:

DCT-positive infants and infants with blood group B suffered significantly higher adverse outcomes. TcB measured at 12 h is predictive of the need for PT and intensive PT. Maximum reticulocytes count is predictive of the severity of ABO incompatibility as evidenced by the need for PRBC transfusions and IVIG therapy.
A Rare Case of Aphallia Associated with Urethral Atresia and Multiple Renal Anomalies
Authors: Ahamed M. Shaiq , Neethu K. K.
Published: October 2022

Aphallia, or penile agenesis, is an extremely rare congenital anomaly, resulting from the failure of the genital tubercle to develop normally during the early period of embryogenesis. We present the case of a baby born at term by normal vaginal delivery to a primi mother with an uneventful antenatal history, except for oligohydramnios detected in the third trimester. Examination of the baby revealed an absence of phallus and external urethral meatus, normally descended testes, a normal scrotum, and a normally positioned patent anal orifice. Subsequent workup of the baby by radiological studies revealed a malrotated right kidney in the midline, multicystic renal dysplasia of the left kidney, and urethral atresia.

Authors: Degerli Mahmut S. , Karayagiz Abdulhak H.
Published: October 2022

Gastric metastasis from renal cell carcinoma (RCC) is rare and associated with poor outcomes. In this case, we report gastric fundic gland metastasis presenting with upper gastrointestinal bleeding in a patient who had a history of nephrectomy due to RCC 14 years ago. Metastasis of any cancer to the stomach is relatively uncommon. Gastric metastasis from RCC, especially isolated fundic gland metastasis, is extremely rare. However, although rare, metastatic RCC to the stomach should be suspected in any patient with a history of RCC who presents with gastrointestinal symptoms.

Authors: Pushkar Kumar , Kaushik S. K. , Nagarjuna P. , Mukherjee Gautam , Teli Prabhakar , Yadav Arun Kumar
Published: October 2022

Background:

Fast-food culture is an uprising trend among the younger age groups. Stressful life due to increased study load, staying away from home, peculiar working hours, etc., negatively influences the food choices of medical students. Hence, this study was conducted to describe the prevalence, pattern, and preferences of fast-food consumption and also to determine the relationship of frequency of fast food with body mass index (BMI) of students of a medical college in Western Maharashtra.

Methods:

A cross-sectional study was done among 398 students of a medical college in Pune for 6 months. The data collection was done using a self-administered pretested structured questionnaire and analyzed using Microsoft Excel and SPSS version 20 software.

Results:

Three hundred and ninety-eight medical students responded. We found a 100% prevalence of fast-food consumption with different frequencies. 13.8% of the students were found to be overweight. Pizza was the most frequently consumed fast food. The taste factor was the most common reason to consume fast food among both sexes. The majority of the study participants (98.5%) were aware that fast foods are hazardous to health. A statistically significant association was found between the frequency of consumption of fast food with the type of diet (P = 0.008) and BMI (P = 0.023).

Conclusion:

High prevalence and preference for fast-food consumption can result in various noncommunicable diseases among students of the medical profession and is a major concern. Thus, there is a need for educating the students regarding nutritional information and counseling to bridge the gap between their knowledge and practice about healthy eating behavior.

Published: October 2022

Introduction:

HIV/AIDS is a challenging disease affecting multiple facets of life. From being a communicable disease alone, it is now posing mental health problems and adjustment disorders as the longevity of HIV/AIDS patients is increasing. In the present study, the quality of life (QOL) among HIV patients was studied, in physical, psychological, environmental, and social domains using the World Health Organization Quality-of-Life Scale (WHOQOL-BREF).

Methodology:

A cross-sectional, observational study was conducted to assess QOL among 140 randomly selected HIV/AIDS patients attending an antiretroviral therapy (ART) center. The WHO QOL BREF questionnaire was used as a tool for collecting data.

Results:

The overall QOL among people living with HIV/AIDS (PLWHA) was 14.29 (±1.9), with the highest mean score in social domain with a mean of 15.42 (±2.73) and the lowest in physical domain with a mean of 14.01 (±2.73). A statistically significant association was found between age, gender, place of residence, disclosure status, and overall QOL. PLWHA with high CD4 count and patients on ART had better QOL.

Conclusion:

Overall QOL in PLWHAs is comparable with other countries, indicating the success of National AIDS Control Programme. Few aspects, if incorporated, can increase further improve QOL among HIV patients.

The Internet of Things (IoT) platforms, despite the wide range of application is not without loop holes of which cyberattackers can take advantage. In order to improve the platform's security while also increasing other features, it has been proposed that blockchain technology be implemented in any IoT system. However, while blockchain technology has many advantages, it is important to consider other options because they all have their own drawbacks that may not be ideal for every use case situation. IoT network devices have limited computer power, storage space, and bandwidth. As a result, these systems are easily prone to assault than other network connected devices, such PCs, cell phones and tablets. With focus on IoT security challenges and the countermeasures offered by the blockchain technology, consensus algorithm, data encryption and smart contracts were discovered to be the common and effective algorithm employed by the blockchain technology in securing Iot systems over time.
Sharp local well-posedness for quasilinear wave equations with spherical symmetry
Authors: Wang Chengbo
Published: October 2022

In this paper, we prove a sharp local well-posedness result for spherically symmetric solutions to quasilinear wave equations with rough initial data, when the spatial dimension is three or higher. Our approach is based on Morawetz type local energy estimates with fractional regularity for linear wave equations with variable

C^1

coefficients, which rely on the multiplier method, weighted Littlewood–Paley theory, duality and interpolation. Together with weighted linear and nonlinear estimates (including weighted trace estimates, Hardy’s inequality, a fractional chain rule and a fractional Leibniz rule) which are adapted to the problem, the well-posedness result is proved by iteration. In addition, our argument yields almost global existence for

n=3

and global existence for

n\ge 4

when the initial data are small and spherically symmetric with almost critical Sobolev regularity.
Meta-analysis of diagnostic test accuracy studies with multiple thresholds for data integration
Authors: Shim Sung Ryul
Published: October 2022

OBJECTIVES: The objective of this study is to introduce methods to use all of the information without omission when individual studies provide multiple effect sizes according to multiple cut-off values (thresholds) during diagnostic test accuracy (DTA) for data integration. For diagnostic test meta-analysis, a general performance method for synthesizing data according to one cut value in one study and a performance method for synthesizing data according to two or more cut values in one study were compared and analyzed.METHODS: As sample data for meta-analysis of DTA studies, 13 DTA studies on prostate cancer (34 effect sizes including total cut-offs) were collected. The summary statistics were calculated and the summary line was analyzed using the “meta”, “mada”, and “diagmeta” packagesof the R software.RESULTS: The summary statistics of the random effect model univariate analysis of the “meta” package with a single cut-off corresponding to the highest Youden index in a single study and those of the bivariate analysis of the “mada” package were highly similar. However, in the bivariate analysis of the “diagmeta” package including all cut-off values, the sensitivity decreased and the specificity increased as the amount of data increased.CONCLUSIONS: Considering the heterogeneity of the summary receiver op erating characteristic curve and the use of all given cut-offs, the use of the bivariate analysis model of the “diagmeta” package is recommended. This study focused on practical methods of DTA rather than theoretical concepts for use by researchers whose fields of study are non-statistics related. By performing this study, we hope that many researchers will use R software to determine the DTA more easily, and that there will be greater interest in related research.

Published: October 2022

The Court of Justice of the European Union has recently issued its judgments in bpost and Nordzucker, in which it considers the scope and interpretation of the ne bis in idem principle (i.e., the protection against double jeopardy) provided by EU law. This article sets out some of the key takeaways from the two judgments and discusses their potential implications in navigating the forthcoming overlap between the Digital Markets Act and EU competition law enforcement. While bpost and Nordzucker provide welcome clarification as regards due process and proportionality in this context, key questions remain unanswered and we can expect more litigation in this area moving forward.

Después de la familia, la educación constituye el espacio socializador donde la persona puede adquirir conocimientos, habilidades y valores culturales, al tiempo que reconoce e interactúa con otro entorno humano. Este acometido debe alcanzarse mediante la alineación de las condiciones físicas, de los procesos curriculares y actuación del docente a las especificidades de cada individuo; sin embargo, los procesos educativos por lo general se diseñan y ejecutan en función de “la mayoría”, dejando de lado aquellos individuos que presentan diferencias en determinadas condiciones cognitivas, de aprendizaje, visuales, mentales, físicas, auditivas, emocionales, sobresalientes, entre otras. Es en este contexto que gran cantidad de niños, jóvenes y adultos pueden “quedar fuera” del sistema, o requerir de un esfuerzo extraordinario para ajustarse a la educación de la mayoría. Es así como nace la Educación Especial como un proceso que procura reconocer y atender la diversidad de los individuos en el sistema educativo, a los fines de generar acciones que permitan satisfacer sus especificidades educativas desde la inclusión, la normalización de los derechos, la individualización y la integración de aquellas personas que presentan alguna condición específica de discapacidad. Este libro se enfoca en abordar las Necesidades Educativas Especiales desde el contexto de la Educación Física, y es necesario partir de este término que nace del informe Warnock de la Comisión Británica de Educación (Warnock, 1978), en ella se detalló varios programas educativos destinados a los niños con discapacidad, estableciendo diferentes parámetros de servicio educativo y la eliminación de barreras que no permitían la atención a la inclusión; también establece que las instituciones educativas deben adaptarse a la enseñanza de los estudiantes con necesidades educativas, siendo un verdadero apoyo para los estudiantes y para los padres de familia.

The Objective of the article is to comprehend the impact of the Covid-19 pandemic on the artisanal fishery sector, and Coastal fishing communities in The Gambia. We carry out qualitative research with a structural questionnaire in which we interviewed selected fish men in the coastal area in the Gambia. The study used a simple random sampling technique, in which from the target population of 6000 people, we selected 384 people randomly as our sample size using the “Yaro Yamane Statistical Formula". The statistical methods used in this study are descriptive statistics, correlation, and Ordinary Least Square (OLS) Method for the analysis. There is a weak negative correlation between the revenue generated from fishing and the management level (correlation coefficient of -0.3561). Despite the covid-19 pandemic, there exists a strong positive correlation between demand for the fish product in the domestic market and revenue generated from fishing (correlation coefficient of 0.7843). Therefore, policymakers should look at the management of fishing to improve it and try to establish a good local market for fishermen to sell their fish products.

The COVID-19 pandemic has had a significant adverse influence on the country’s economic and social situation, especially with regard to the tourism industry. This study examines the implications of the global pandemic on the tourism industry in Sabah, the study will consider the impact of the movement control order (MCO) and other mitigating measures adopted by tourism industry players. The survey and focus group findings indicate that the pandemic has had a significant impact on the tourism industry in the state, compelling operators and policymakers to re-evaluate current response strategies. The adoption of the MCO in response to the pandemic has resulted in business interruptions and income loss for tourism industry service-providers, with most of them losing more than 80% of their revenues. Diversification is one of the strategies used by operators in the industry to ensure long- and short-term viability. Meanwhile, a government vaccination program is a long-term strategy aimed at ensuring that the tourism sector in Sabah can return to normalcy. As with any study, this study too has limitations in terms of the number of industry sectors studied and sample size used to collect data.

Pea crab infestations reduce the quality of bivalves, decreasing their market value and may result in consignment rejection during exportation in the bivalve aquaculture industry. This study investigates the prevalence of pea crabs in four different species of bivalves collected in habitats in the Setiu Wetland Lagoon, Terengganu. A total of 771 samples of bivalves including Geloina expansa (Mousson, 1849), Meretrix meretrix (Linnaeus, 1758), Anadara cornea (Reeve, 1844) and Magallana bilineata (Röding, 1798) were collected during low tide, with shell length measurements of 5.44 ± 1.3, 2.67 ± 0.6, 3.96 ± 0.6 and 0.00 ± 0.0, respectively. No length measurement was recorded for M. bilineata due to the unequal sizes of the shells. A total of 30 pea crabs were harboured with single colonisation and all of them were females. The pea crabs were identified to be from the genus Arcotheres sp. Manning, 1993 with carapace subcircular and invisible eyes in the dorsal view, chela slender, half of the palm length dactylus, palm slender, dactylus and pollex straight, propodus spatulate with apex rounded, dorsally and distally setose, slender exopod, dorsally and ventrally unarmed ambulatory legs, and relative length of meri P3>P2=P4>P5, P2 and P3 dactyl less than half of the propodal length. The prevalence of pea crabs was higher in G. expansa (P: 9.73%), followed by M. bilineata (P: 1.59%) and M. meretrix (P: 1.12%) which were highly influenced by the host size. No pea crab infestation was found in A. cornea probably due to muddy and strong waves area. Overall, the present study revealed that host size and habitat were the main factors affecting the colonisation of pea crabs in bivalves from the Setiu Wetland Lagoon, Terengganu.

At the height of the COVID-19 pandemic, the Malaysian government took precautionary action to minimise the spread of the coronavirus with the implementation of the Movement Control Order. This move led to employees in non-essential sectors, including the construction sector, being required to work from home. This study aims to investigate the challenges of working from home and the mitigation actions to overcome the challenges from the perspective of quantity surveyors. A questionnaire survey was used for the data collection exercise. The responses of 360 participants were recorded and analysed. The data collected were analysed using the Statistical Package for the Social Sciences (SPSS) software using the frequencies, percentage and mean analysis. Cronbach’s alpha was used to measure the reliability of the questionnaire survey.

Paraquat is the most widely used herbicide in agricultural activities for land preparation and weed control. Uncontrolled usage and poor waste management will introduce the chemical into the aquatic ecosystem due to agricultural runoff, causing harm to non-targeted aquatic species, especially fish. Therefore, this study was performed to evaluate the histological alterations of the gill, liver and kidney of the freshwater fish Anabas testudineus. Fish were exposed to four paraquat concentrations (2.0, 5.0, 12.0 and 15.0 mg/L) for 96 hours in controlled water parameters and without feeding. Following treatment, all fish were pithed and their gills, livers and kidneys were collected. Histopathological analysis with semi-quantitative scoring lesions were performed to determine the severity of the tissue changes in each fish organ. Histopathological changes in the gills after 96 hours of paraquat exposure showed lamella curvature, hyperplasia, edema, blood vessel congestion and necrosis compared with the control group. Histological changes, like degeneration in hepatocytes and necrosis were observed in the livers and kidneys exposed to 2.0-12.0 mg/L of paraquat. Prominent histopathological changes were observed in 15.0 mg/L of paraquat exposure, including nuclear pyknosis and necrosis. Overall, this study demonstrated deleterious effects of paraquat on the tissues of A. testudineus. The histopathological changes were proportional to the paraquat concentration and may impair organs’ vital functions which in turn affects the fish’s health.

To meet the goal of sustainability and transition to a green economy, renewable energy sources have to be used. Although many countries have declared their transition to a smart, green and sustainable economy, there is still modest evidence of achieving climate change goals, Sustainable Development Goals and other related societal and environmental goals. This paper aims to give an overview of the current global and regional trends, and the strategic frameworks on the use of wind energy to clarify its potential, especially offshore wind energy, using the example of the United Kingdom as one of the global leaders in this area. For several decades, the United Kingdom has implemented various regulations and mechanisms to improve climate action and the transition to a green economy. It offers specific Contract for Difference schemes to offshore wind producers, under which they are entitled to a specially defined purchase price of electricity produced for 15 years. Thus, the United Kingdom is one of the global leaders in offshore wind energy generation. Initiatives, strategic frameworks and regulations in the United Kingdom can serve as guidelines for other countries in developing their own strategic framework.

The impact of agricultural systems on the economy, environment and society should be monitored so that efficient and fair chains can be developed in the context of sustainable development objectives. Sustainability indicators can be used for this purpose and their applicability to regional realities should be assessed. The objective of the present research is to investigate the influence of environmental and social indicators on economic indicators from the perspective of the family farmers that participated in the Agroindustry Arrangement in southern Brazil. The study was based on surveys involving producers and managers of family farms associated with five cooperatives. The responses of 81 family farmers and cooperative managers to 30 indicators were assessed using the ordinary least squares regression. Fourteen of the indicators were economic (the dependent variable), 11 were environmental and five were social (the independent variables). Positive influences on the environmental indicators relating to water (the financial and operational aspects and productivity), air (the financial and operational aspects) and soil (the operational aspects) were identified. The social indicators relating to food health and safety (the financial aspects and productivity) and opportunities (the operational aspects) had a positive impact on the economy. Therefore, we concluded that there is a dependent relationship between the sustainability indicators which shows the importance of the social and environmental dimensions for the family farmers’ economy. Such results indicated that producers from familiar agro-industry are aware of the importance of the environmental and social aspects to achieve success in the economic aspects and they can be important for the definition of new sustainability policies in regions, where agro-industrial production arrangements are relevant to the economy, as in southern Brazil.

The influence of the acidic treatment of peat on its sorption properties has been studied by means of optical emission spectrometry with inductively coupled plasma (ICP-OES) and pH-metry methods. Untreated peat of the Vardenis deposit, Armenia, and acid-activated peat were used as sorption materials. As an activation process, we consider preferably the elimination of metal ions captured on the peat surface. During this active sorption groups (particularly acetic) are released from the surface and such acidic groups together with other functional groups begin to act according to the cation exchange mechanism.

Plants are valuable sources of antioxidants, which could have beneficial effect on human health. In this respect flavonoids and other polyphenolic compounds have gained the greatest attention. The present study was undertaken to evaluate the in vitro antiradical activity of different extracts (ethanol, hexane, acetone, chlorophorm and methanol) of Artemisia vulgaris L., A. fragrans Willd., A. absinthium L. and A. splendens Willd., represented in Armenian flora. 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay was used to measure the radical scavenging activity of extracts obtained from Artemisia species. A. fragrans methanol and chlorophorm extracts possess the highest antiradical activity with IC50 value of 87 µg/mL and 98 µg/mL, respectively. The total flavonoid content in plant extracts was determined employing AlCl3 colorimetric assay. The content of total flavonoid compounds of A. fragrans methanol extract was 15.3±0.3 μg QE/mg. The Folin–Ciocalteu assay was used to determine the total phenolic content of studied extracts. The contents of total phenolic compounds of A. fragrans chlorophorm and methanol extracts were 55.9±1.7 μg and 87.3±1.8 μg of GAE/mg, respectively. In the other cases this parameter value was lower than 40 μg of GAE/mg indicated.
