Published: July 2022

Abstract. For an effective disaster risk mitigation plan and for building a society more resilient to natural disasters, it is essential to understand the factors that are related to social vulnerability as an important dimension to social risk. This study aims to identify the associations between socio-economic and socio-demographic household characteristics and earthquake related social vulnerability using survey data collected from 41,093 households in Istanbul. Machine learning models, namely: logistic regression, classification tree, random forest, support vector machine, naive bayes, artificial neural network, and K-nearest neighbours, were employed to classify households according to their social vulnerability status. Due to the disparity of class size for the outcome variable, subsampling strategies were applied for dealing with imbalanced data. Artificial Neural Network (ANN) was found to have the optimal predictive performance when random majority under sampling was applied (AUC: 0.813). The results from the ANN method indicated that not having social security, living in a squatter house and having high risk of job loss after an earthquake were among the most important predictors for increasing social vulnerability risk. Additionally, the level of education, the ratio of elderly persons in the household, owning a property, household size, ratio of income earners, and having savings were associated with vulnerability. An open access R-shiny web application was developed to visually display the performance of ML methods, important variables for the social vulnerability risk classification and the spatial distribution of the variables across Istanbul neighbourhoods. The machine learning methodology and the findings that we present in this paper can serve as a guidance for decision makers in identifying and prioritising action towards target groups to reduce their vulnerability risk prior to earthquakes.
Rainfall thresholds estimation for shallow landslides in Peru from gridded daily data
Authors: Millán-Arancibia Carlos , Lavado-Casimiro Waldo
Published: July 2022

Abstract. The objective of this work was to generate and evaluate regional rainfall thresholds obtained from a combination of high-resolution gridded precipitation data (PISCOpd_Op), developed by the National Service of Meteorology and Hydrology of Peru (SENAMHI), and information from observed shallow landslide events. The landslide data were associated with rainfall data, determining triggering and non-triggering rainfall events with rainfall properties from which rainfall thresholds were determined. The validation of the performance of the thresholds was carried out with events that occurred during 2020 and focused on evaluating the operability of these thresholds in landslide warning systems in Peru. Thresholds were determined for 11 rainfall regions. The method of determining the thresholds was based on an empirical–statistical approach, and the predictive performance of the thresholds was evaluated from the “true skill statistics” (TSS) and the area under the curve (AUC). The best predictive performance was obtained by the mean daily intensity-duration (Imean – D) threshold curve, followed by accumulated rainfall E. This work is the first attempt to estimate regional thresholds on a country scale in order to better understand landslides, and the results obtained reveal the potential of using thresholds in the monitoring and forecasting of shallow landslides caused by intense rainfall and in supporting the actions of disaster risk management.
Mechanism of generation and propagation characteristics of coastal trapped waves in the Black Sea
Authors: Aydın Müjdat , Beşiktepe Şükrü Turan
Published: July 2022

Abstract. Coastal trapped waves (CTW) are a major mechanism to
distribute energy from the atmosphere in the ocean and play a significant
role in large-scale, low-frequency sea-level and current variability in
continental shelf and slope areas. Despite their significance for coastal
dynamics, observational evidence of the influence of CTWs on the large-scale
circulation is rather limited. In this study, mode-1 coastal trapped waves
that were captured at sea-level stations at five locations along the
southern coast of the Black Sea are examined together with sea surface
height reanalysis from the Copernicus Marine Service to reveal their generation
mechanisms and role in the coastal dynamics. It is found that the CTWs were
formed when water accumulated on the western shelf after gale-force
alongshore winds in the western Black Sea. Excited waves propagate
along the Black Sea coast from west to east with a speed of 2.3–2.6 m s−1 and transport the atmospherically induced energy all over the Black
Sea. The coastal current generated by the CTWs (on the order of 1 m s−1 in magnitude)
and the main Black Sea current merge and flow eastward as a single
structure, resulting in intensification of the Black Sea circulation during
winter. Hence, we present evidence of the influence of CTWs on the
large-scale circulation.
Liberty and Suspension in Locke’s Essay
Authors: Leisinger Matthew A
Published: July 2022

I argue for two controversial claims about Locke’s account of liberty in Essay 2.21. The first claim is that Locke does not identify liberty with freedom of action. Instead, Locke places further conditions on liberty beyond to the power to perform or forbear an action at will. The second (and closely related) claim is that Locke takes the power to suspend and examine desire to be necessary for liberty—in other words, that possession of the power to suspend and examine desire is one such further condition upon liberty.

Gene Therapy for Hemophilia
Authors: Repaka Venkata , Lomboy Daniel , Castro Priscilla
Published: July 2022

Hemophilia is an X-linked recessive genetic disorder in which the body has an inability to clot, leading to increased risk of mortality for individuals if a bleeding episode were to occur. Traditional hemophilia treatments such as prophylactic factor replacement therapy of recombinant factor VIII and IX, have been proven to be costly and do not provide a long-lasting protection during bleeding episodes.(1) In recent years, use of Adeno-associated viral vectors (AAV) gene therapy has been explored as a potential alternative due to efficient gene delivery and tissue tropism, overall safety and efficacy, and longer-lasting effects.(2) However, concerns over inhibitor development still stands as a majorly significant treatment complication that burdens the steady progression of long-term treatment. This review article seeks to provide an overview of the current state of AAV-based gene therapy as a treatment for Hemophilia.
The sphere of ECtHR jurisprudence application in the activity of criminal investigation bodies of law
Authors:   National Institute of Justice, Republic of Moldova, Oganesean Armen
Published: July 2022

In this article, we have investigated the theoretical and practical aspects of the sphere of application of ECtHR case law and interpretations given by the ECtHR in the activity of criminal investigation bodies of law, as well determining in the national criminal process the particularities of ECtHR case law application at the criminal investigation stage. We analyzed the perspectives of using the precedents of the European Court in the criminal process with the revelation of the particularities and advantages of its applicability for the exponents of the criminal investigation bodies. The rule of law is one of the key principles of the Convention for the Protection of Human Rights and Fundamental Freedoms and implies that an interference by the authorities on a person's rights must be subject to effective control, especially if the law gives the executive broad powers. This control becomes particularly important in the context of the prosecutor's duties in the criminal investigation phase, therefore, in this article we studied the most relevant aspects of the application of ECtHR jurisprudence in the activity of procedural subjects in the criminal investigation phase.

Published: July 2022

Background and Purpose: This investigation evaluated the antidiabetic activity of the aqueous leaf extract of Strophanthus hispidus (SHP) in fructose/low-dose streptozotocin-induced type 2 diabetic rats due to the folkloric use of the root in traditional medicine for the treatment of both type 1 and type 2 diabetes mellitus.

Methods: Fructose/low-dose streptozotocin-induced diabetic rats were allotted into five groups of eight rats each and administered S. hispidus root extract at doses of 50, 100 and 200 mg/kg; glibenclamide 5 mg/kg; and normal saline 10 mL/kg respectively. A sixth group that consisted of non-diabetic rats were given distilled water (10 mL/kg). Treatment was by the oral route for 28 consecutive days.  Fasting blood glucose (FBG) level was checked at intervals of 7 days. Blood samples were collected on day 28 an hour after the administration of the last dose, for the assay of serum levels of enzymes, lipids, insulin, haemoglobin (Hb), and glycosylated haemoglobin (HbA1c).

Results: The aqueous root extract of SHP demonstrated a significant (P<0.05) reduction in FBG compared with diabetic non-treated control. The doses of 50, 100, 200 mg/kg of aqueous SHP and 5 mg /kg of glibenclamide elicited 82.07%, 88.83%, 88.03% and 78.01% reduction in FBG level respectively at day 28. The extract treated rats displayed significant (P<0.05) decrease in urea, ALT, AST, ALP, LDL, TC, TG and HbA1c levels and significant (P<0.05) increase in HDL and Hb levels. Significant (P<0.05) dose-independent upsurge in serum insulin level was equally observed.

Conclusion: The aqueous root extract of SHP has blood glucose lowering potential and improves some of the imbalances that occur in diabetes.

Authors: Listyowati Dina , Suparwitri Sri , Andusyana Farmasyanti Cendrawasih
Published: July 2022

Background: Olive oil is a natural source of phytoestrogens and antioxidants similar to mammalian estrogen. The substance increases osteoblast differentiation and osteoprotegerin (OPG) expression. Objective of the study: To examine the effect of giving olive oil on OPG expression of gingival crevicular fluid in the orthodontic tooth movement among old and young guinea pigs. Methodology: The four groups of guinea pigs (n = 3) consisted of old guinea pigs given olive oil (OO), old controls (OC), the young given olive oil (YO), and young controls (YC). The teeth were movedreciprocally to distal by a 0.35 N open coil spring which was attached to the bracket of the lower incisors. The YO group was given olive oil at 0.7ml/day dosage and the OO group had 1.86ml olive oil administered per day until day 14. OPG expression was analyzed in gingival crevicular fluid (GCF) sample using the enzyme-linked immunosorbent assay (ELISA) on days 0, 7, and 14. Retrieved data was analyzed using Three-way ANOVA Statistic Test followed by Post Hoc LSD Test. Results: The statistical test showed that olive oil increased OPG expression in old and young guinea pigs (p<0.05), and OPG OO expression was comparable to that in YC day 7. OPG YO expression was higher than OO (p <0.05). Increasing duration of olive oil application led to higher OPG expression (p <0.05). There was a correlation between olive oil and age and duration of administration (p <0.05). Conclusion: Olive oil increased the OPG expression on GCF of old and young guinea pigs during orthodontic tooth movement, with the highest OPG expression in YO day 14.

Published: July 2022

Doxazosin mesylate (DX) is an antihypertensive agent belonging to BCS class II. There is no reported literature available on development of spectrophotometric method for its analysis in bulk and pharmaceutical dosage forms using 0.1N HCl. Thus, attempt was made to develop and validate a new UV spectrophotometric method using 0.1N HCl as the solvent for its quantitative estimation in tablets that would be fast, simple, accurate, and sensitive. DX had a maximum absorbance wavelength of 245 nm and was linear with a correlation coefficient (R2) of 0.9981 across the concentration range of 2-14 μg/mL. The present method was utilized to determine the drug content of two commercial brands namely; brand I and brand II. The estimated amount of DX was 99.13% and 99.02% in these brands, respectively. The proposed method generated results that confirm the label claim and was accurate, precise, sensitive, and rugged during its validation study. The accuracy of the technique was tested using recovery research at three different levels, namely 80%, 100%, 120%, and the percent recovery rate was determined between 98% and 102% suggesting that the proposed approach is accurate. Precision and robustness were within the acceptable limits, complying with ICH standards. The proposed method could be used to quantify DX in API and dosage forms.

The aim of the study is to evaluate the association of some molecular genetic markers with progressive atherosclerosis.

Material and methods. In total, the study included 202 patients (147 men and 55 women), who were divided into 2 groups. The 1st (main) group included patients with coronary artery disease (100 people) who had a combination of two or more cardiovascular events during the last 2 years before inclusion: myocardial infarction or unstable angina pectoris, arterial stenting for urgent indications (coronary and peripheral), stroke; acute ischemia, thrombosis or amputation of the lower extremities. The 2nd group (comparisons) included 102 patients with coronary artery disease who did not have any of the above cardiovascular events during the last 2 years before inclusion. DNA was isolated from peripheral blood samples by phenol-chloroform extraction.

Results. In the group with progressive atherosclerosis at the age of 55 years and older, the AA rs3746444 genotype of the MIR499A gene was absent in both men and women, while in the control group its frequency reached 8.3 % (p = 0.044). The odds ratio of detecting the carriage of the heterozygous genotype AG of the rs6922269 polymorphism of the MTHFD1L gene in the group with progressive atherosclerosis is 0.5 times lower compared to the control group (95 % confidence interval 0.3–0.9; p = 0.034).

Conclusions. Carrying the AA genotype rs3746444 of the MIR499A gene is a conditionally protective factor against the development of progressive atherosclerosis at the age of 55 years and older. Carrying the AG genotype of the rs6922269 polymorphism of the MTHFD1L gene is associated with a reduced likelihood of developing progressive atherosclerosis in patients with CAD.
Nord Stream 2: The Expectations of Russian Citizens from Increasing Gas Exports to Europe
Authors: Tsoy Karalina A.
Published: July 2022

Natural gas is one of the key exports of Russia. The country exports gas via pipelines and liquefied natural gas (LNG) via ships. In 2018, the construction of the Nord Stream 2 (NS2) project began and finished in early September 2021, despite all challenges. The purpose of the NS2 is to supply affordable natural gas to European markets while helping them improve energy security, especially for land-locked countries that are ill-suited to receive LNG. The current study aims to gauge the expectations of Russians from the increase in Russian gas exports to Europe resulting from the completion of the NS2. From the literature, some important factors were identified. Primary data was collected from the Russian citizens, and the Grey Relational Analysis model was used to analyze data and rank the key expectations of Russians from the increasing gas supply to the European consumers. The results are interesting and can help the policy-makers know the expectations of the Russian taxpayers.
Secondary School EFL Teachers’ Formative Assessment Practices and Their Impact on Learning
Authors: Ben Hmida Amira
Published: July 2022

The positive impact of formative assessment (FA) on learning was taken as a conventional wisdom in education for decades, yet the empirical evidence supporting its prospective benefits on learning especially from students’ perspectives remains distinctively lacunary. To fill this gap, this research project aimed at examining the FA practices employed by Tunisian EFL teachers and their impact on students’ learning by putting students’ perspectives at the center of the debate. Semi-structured interviews (n = 5) were addressed to 5 secondary school teachers to examine the FA practices they implemented in their classrooms. Students (n = 100) were administered an internet-based survey to probe their insights as to the impact of these practices on their learning. To cross-check students’ answers to the internet-based survey, comparisons of their test scores between two summative tests (STs) occurring before and after the implementation of the specific FA practices were conducted. Major results showed that EFL teachers referred to providing their students with oral and written feedback, sharing with them the used assessment criteria, and enhancing peer and self-assessment. While students believed that these FA practices are helpful as they enabled them to determine their strengths and weaknesses and to identify what to do to improve their learning, no significant improvement was found in students’ test scores between the two STs. Moreover, students seem to always favor their teachers’ assessment over that of their peers or themselves. These results challenge the entrenched beliefs about FA as the ultimate tool to enhance students’ learning outcomes and open up more venues for further research that land more powerful empirical support for its prospective benefits on learning.
