Abstract. Deep learning (DL) models are popular but computationally expensive, machine learning (ML) models are old-fashioned but more efficient. Their differences in hydrological probabilistic post-processing are not clear at the moment. This study conducts a systematic model comparison between the quantile regression forest (QRF) model and probabilistic long short-term memory (PLSTM) model as hydrological probabilistic post-processors. Specifically, we compare these two models to deal with the biased streamflow simulation driven by three kinds of satellite precipitation products in 522 sub-basins of Yalong River basin of China. Model performance is comprehensively assessed by a series of scoring metrics from the probabilistic and deterministic perspectives, respectively. In general, the QRF model and the PLSTM model are comparable in terms of probabilistic prediction. Their performance is closely related to the flow accumulation area of the sub-basin. For sub-basins with flow accumulation area less than 60,000 km2, the QRF model outperforms the PLSTM model in most of the sub-basins. For sub-basins with flow accumulation area larger than 60,000 km2, the PLSTM model has an undebatable advantage. In terms of deterministic predictions, the PLSTM model should be more preferred than the QRF model, especially when the raw streamflow is poorly simulated and used as an input. But if we put aside the model performance, the QRF model is more efficient in all cases, saving half the time than the PLSTM model. This study can deepen our understanding of ML and DL models in hydrological post-processing and enable more appropriate model selection in practice.

Published: November 2022

Abstract. Few studies have explored the stemflow double-funnelling phenomenon, although subsurface flow along roots and macropores plays a significant role in determining hydrological responses in forested catchments. In this study, a stemflow experiment on Pinus sylvestris L. (Scots pine) used artificial tracers to view and quantify the preferential flow of stemflow water after infiltration into the soil. Forty-one litres of water labelled with enriched deuterium and Brilliant Blue FCF were applied at a flow rate of 7 L h-1 to the stem of a pine tree, which corresponds to stemflow caused by about 50 mm rainfall. TDR probes were distributed around the tree trunk and in depth profiles to measure high-resolution volumetric water content. One day after the stemflow discharge, soil pits were dug in the different cardinal directions and at varying distances from the tree. Photographs were taken for imaging analysis to quantify preferential flow metrics. Soil samples were taken from the different profiles to analyse dye concentrations and isotopic compositions. We found that stemflow infiltrated through an annulus-shaped area around the tree base. We observed a heterogenous spatiotemporal soil moisture response to stemflow and the occurrence of shallow perched water tables around the tree trunk. Dye staining demonstrated that stemflow infiltrated primarily along the surface of coarse roots and also through macropores. The dye coverage was less extensive close to the soil surface and increased with depth and with proximity to the tree trunk. Lateral flow was also observed, mainly in the shallow soil layers. A set of metrics demonstrated the prevalence of preferential flow. Deuterium and Brilliant Blue FCF concentrations correlated with each other significantly. The concentrations decreased at increasing distance from the tree trunk, indicating dilution and mixing with residual soil water. Macropores, coarse roots (living or decayed) and perched water tables produced a complex network regulating the preferential flow. Our results suggest that stemflow heavily affects soil moisture distribution, and thus also groundwater recharge and surface runoff. Our study provides insights into the physical processes controlling stemflow belowground funnelling and improves our understanding of forest-water interactions.

Quantitative estimates of changes in wind energy resources in the Arctic were obtained using the RCA4 regional climate model under the RCP4.5 and RCP8.5 climate change scenarios for 2006-2099. The wind power density proportional to cubic wind speed was analyzed. The procedure for the model near-surface wind speed bias correction using ERA5 data as a reference with subsequent extrapolation of wind speed to the turbine height was applied to estimate the wind power density (WPD). According to the RCA4 simulations for the 21st century under both anthropogenic forcing scenarios, a noticeable increase in the WPD was noted, in particular, over the Barents, Kara, and Chukchi seas in winter. In summer, a general increase in the WPD is manifested over the Arctic Ocean. The changes are more significant under the RCP8.5 scenario with high anthropogenic forcing for the 21st century. According to model projections, an increase in the interdaily WPD variations does not generally lead to the deviations of wind speed to the values at which the operation of wind generators is unfeasible.

An impact of global warming on river runoff into the Arctic seas is discussed. River runoff is one of the main components of the Arctic freshwater balance. Annual total river runoff is determined as the sum of runoff of six rivers: the Ob, Yenisei, Lena, Kolyma, Indigirka, and Mackenzie. The indices of zonal, meridional, and general circulation were calculated to assess the effect of atmospheric circulation. Correlations between the indices and surface air temperature and precipitation in the catchment areas confirmed the most significant influence of atmospheric transport on climatic conditions in the cold season. It was stated that annual total river runoff increased during 1979-2019, but the occurrence of peak discharges was reduced.

Published: November 2022

Statistical aspects of the quantitative estimation of the climate change polar amplification (PA) are considered. A theoretical study is provided of the distribution density for the PA sample coefficient defined as the ratio of the linear trend coefficients of spatially averaged surface air temperature. It is shown that heavy tails of the distribution lead to instability of the PA sample estimates. A statistically valid quantification of the PA can be obtained from the results of the ensemble modeling of climate change based on the Fieller’s method. The applicability of the method in the case of a non-stationary climate system response to external forcing is considered.

A technique is presented for monitoring and short-range forecasting of resource convective clouds suitable for obtaining additional precipitation by seeding with hygroscopic reagents. The short-range forecast of resource clouds is based on the analysis of a set of favorable conditions (a system of certain predictors). The predictors are computed with the global GFS model and are visualized as forecast maps. Predictor ratios are established empirically based on the analysis of meteorological conditions in a current season for the study region. The developed technique is tested using the data of convective clouds monitoring in the Stavropol region. The forecast results with a one-day lead time are in satisfactory agreement with the observed parameters of convective clouds.

In generators traditionally used for weather modification, combustion products are released either directly through the holes in the body (seeding cartridges, aircraft aerosol generators) or through the nozzle blocks of antihail rockets. At the same time, under certain conditions, a secondary ignition of combustion products is possible with an almost complete burnout of active substances and a significant (by several orders of magnitude) decrease in the ice-forming activity of the generated aerosol. The paper discusses a possibility of a significant change both in the physical and chemical properties of the ice-forming aerosol in the organization of the release of combustion products through the path of the de Laval nozzle operating in a supersonic mode.

In Mozambique 43% of children aged between 0 and 5 years old suffer from chronic malnutrition. Problems related to nutritional status are more prevalent in rural areas of the country, especially in the north, with greater emphasis on the provinces of Nampula and Cabo Delgado. In the various prevention and resolution measures, the communication tools, their strategies and actions can contribute to the information, awareness and awareness of the populations. The study presented here is the result of a doctoral investigation focusing on the effectiveness of social marketing campaigns to reduce malnutrition rates in children in the Monapo district, proposed by a non-governmental organization, which for ethical and protection reasons, the fictitious name SD was used. In this way, the main objective is based on understanding the attitudes and behaviors of pregnant mothers and mothers of children from 0 to 5 years of age in relation to the nutrition campaign. Thus, from a qualitative methodological approach perspective, in the context of the interpretive paradigm, the main results of the present investigation reveal a strong awareness of mothers about the risks associated with the problem, the benefits present in the ideal behavior and also in the face of a clear will to follow in accordance in the face of behavior. However, contextual and environmental issues proved to be a major obstacle to the practical applicability of these behaviors.

Published: November 2022

Dysmenorrhea with high prevalence has been categorized as primary dysmenorrhea (PD) and secondary dysmenorrhea due to differences in pathogenesis. A significant number of reproductive females suffering from monthly menstruation have to deal with negative impacts on their quality of life, work/study productivity, activities, and social relationships. In addition to medical treatment, exercise has been recognized as a complementary and alternative strategy for disease prevention, alleviation, and rehabilitation. This study aimed to investigate the potential effects of exercise on the severity of primary dysmenorrhea, physiological modulation, and physical fitness. Participants consisted of university students who were enrolled in the study and divided into a non-PD (Control) and a PD group based on recruiting criteria, the latter being randomly assigned to either an untreated dysmenorrhea group or a dysmenorrhea group that underwent 10 weeks of high intensity interval training (HIIT) exercise (Dysmen and DysmenHIIT, respectively). The DysmenHIIT group used spinning bikes and the training intensity was validated by heart rate monitors and BORG rating of perceived exertion. Forms containing participant information (premenstrual symptoms, menstrual distress, and a Short Form McGill Pain Questionnaire) as well as physical fitness, biochemical variables, hormone and prostaglandin (PGE2 and PGF2α) levels were assessed before and after the exercise intervention. After intervention, premenstrual symptoms (anger, anxiety, depression, activity level, fatigue, etc.), menstrual distress symptoms (cramps, aches, swelling, etc.), and pain severity were shown to be significantly mitigated, possibly through hormone (estradiol, prolactin, progesterone, and cortisol) modulation. Furthermore, high-sensitivity C-reactive protein (HsCRP), PGE2 and PGF2α levels were also down-regulated, resulting in the amelioration of uterine contraction and inflammation. Participants’ physical fitness, including cardiovascular endurance and explosive force, was significantly improved after HIIT. The 10-week HIIT spinning bike exercise used in this study could be employed as a potential and complementary treatment for PD symptoms alleviation and considered as part of an educational health plan for promoting women’s health. However, the effects of HIIT utilizing different exercise methods and accounting for different age populations and secondary PD warrant further investigation.

For decades, chronic pain was managed with an almost conventional approach of using a wide range of analgesic spectrum, surgical approaches and complex interventional pain techniques to modulate or even interrupt pain pathways. These different approaches carry many pharmacological hazards together with the lack of efficacy and safety of many interventional and surgical management techniques for chronic pain have mandated searching for other effective therapies including alternative treatments. Cannabinoids are naturally occurring substances that are derived from Cannabis sativa L. The usage of cannabinoids and their related synthetic chemical compounds has emerged as a choice in the management of different chronic pain conditions is being evaluated, however, the efficacy is still not consistently established. In the present investigation, therefore, we discuss the different aspects related to cannabinoids and their implications in the management of chronic pain conditions. This review will also discuss the safety profile of the cannabinoids together with the legal considerations that hinder their use in different countries.

Phenothiazines, a diverse class of drugs, can be used to treat multiple mental health and physical conditions. Phenothiazines have been used for decades to treat mental illnesses, including schizophrenia, mania in bipolar disorder, and psychosis. Additionally, these drugs offer relief for physical illnesses, including migraines, hiccups, nausea, and vomiting in both adults and children. Further research is needed to prove the efficacy of phenothiazines in treating physical symptoms. Phenothiazines are dopaminergic antagonists that inhibit D2 receptors with varying potency. High potency phenothiazines such as perphenazine are used to treat various psychiatric conditions such as the positive symptoms of schizophrenia, the symptoms of psychosis, and mania that can occur with bipolar disorder. Low/mid potency phenothiazines such as chlorpromazine antipsychotic drugs that have been used to treat schizophrenia and schizophrenia-like disorders since the 1950s and are utilized in numerous disease states. The present investigation aims to elucidate the effects of phenothiazines in clinical practice.

Authors: GÖRMEZ Gül
Published: November 2022

Objective: Rosa canina L., Malus domestica L., Prunus persica L Siebold & Zucc., Cydonia oblonga Mill., Armenica vulgaris Lam., and Pyracantha coccinea M.Roem. are important fruits of the Rosaceae family, used in a wide variety of industries such as food, perfume, cosmetics, paint, beverage, and for economic and medical purposes. Although medicinal plants act with their natural components against diseases, they can cause toxic and unde-sirable side effects. It is important in terms of human health and food safety to examine plants for their heavy metal, mineral, protein and antioxidant capacities before they are used for treatment, food or cosmetic purposes. The heavy metals (Al, Cr, Cu, Co, Zn), minerals (Fe, Mg, Na, Ca, K), protein and antioxidant capacities of some medicinal plants grown in Van-Turkey were determined and their safety in terms of food and in medical uses were evaluated.
Material and Method: After the lyophilized plants were solubilized with a wet burning (microwave) device, Al, Cr, Cu, Co, Zn, Fe, Mg, Na, Ca, K elements were analyzed in the ICPOES device. Protein analyzes were per-formed by the Gerthardt Dumatherm method. Cuprac method was used for antioxidant capacity analysis.
Results: The measured values were ranged between (in mg kg−1) Al 10.753-20.407, Co 0.007-9.664, Cr 0.119-0.411, Cu 2.409-6.554, Zn 23.426-33.891, Ca 743.0-2501.7, Fe 31.7-117.6, K 3555.2-4202.9, Mg 498.7-1982.9, Na 839.8-1616.0 and Protein (%) 1.45-5.53. Detected heavy metal amounts are in general within acceptable limits determined by WHO (World Health Organization). While the Cuprac values of the plants ranged between 1.13 and 3.62, the Cuprac values for the standard synthetic antioxidants α-tocopherol and BHT were determined as 2.14 and 3.21 µmol TE g−1DW, respectively. In particular, it was determined that Rosa canina extracts showed high activity (3.62 µmol TE g−1DW) comparable to α-tocopherol and BHT.
Conclusion: : For centuries, human beings have benefited from plants in the treatment of diseases. Due to the severe side effects of synthetic drugs, people in the modern world also turn to medicinal plants for the treatment of many diseases. However, conscious consumption of medicinal plants by examining them especially in terms of heavy metal amounts will prevent serious health problems in the long run. The study showed that the heavy metal amounts of some plants belonging to the Rosaceae family, which are cultured, used for therapeutic pur-poses and consumed as fruit by the people of Van, are safe for human consumption and medical uses, and their micronutrient, protein and antioxidant capacities are at the desired level for healthy nutrition and therapeutic uses.

Introduction: Patients with multiple comorbidities who have coronavirus disease 2019 (COVID-19) have high morbidity and mortality. Glucose-6-phosphate dehydrogenase (G6PD) deficiency has been shown to have an enhanced effect on coronavirus in an earlier study.

Methods: We conducted this comparative observational study to evaluate the effects of COVID-19 disease on G6PD deficiency based on the hematologic parameters, COVID-19-related hospitalizations, and mortality in the state of Qatar between January 2020 and May 2020 at four designated COVID-19 facilities. We identified 41 patients with G6PD deficiency who had documented COVID-19 infection. We compared the results with 241 patients with COVID-19 infection who tested negative for G6PD deficiency.: Results: Comparing the COVID-19 positive G6PD deficient with COVID-19 positive G6PD normal activity showed that G6PD normal group had higher white blood cell count (WBC), absolute neutrophil count (ANC), lymphocytes, eosinophils, and monocytes counts versus the G6PD deficient group (p < 0.001).

Conclusions: When compared with COVID-19 patients with normal G6PD, patients with COVID-19 infection and G6PD deficiency had lower total WBC, ANC, lymphocyte, monocyte, and eosinophil counts. However, no evidence of increased hemolysis, thrombosis, morbidity, or mortality was observed in COVID-19 patients with G6PD deficiency.

Introduction: Primary spontaneous pneumothorax (PSP) is a common medical emergency. Its treatment includes simple observation, needle thoracentesis, pleural catheter, video-assisted thoracoscopy (VATS), and open surgery. We aimed to establish the demographic, clinical characteristics, and 12-month recurrence rate of patients with PSP in four hospitals of the Hamad Medical Corporation, Qatar.

Materials and methods: We conducted a retrospective analysis of patients >14 years old who were admitted with PSP from January 1, 2017 to December 31, 2019. The patients were followed up for 12 months for the recurrence of PSP.

Results: Out of 246 patients enrolled in this study, 223 (90.7%) were males and 23 (9.3%) were females. Their mean age was 29.1 ± 9.59 years and their mean body mass index (BMI) was 21.7 ± 4.22 kg/m2. Of these, 123 (51.2%) patients were smokers. Chest pain was the most common presenting complaint (82.5%). A total of 59 (23.98%) patients had a small pneumothorax, whereas 187 (76.01%) patients had a large pneumothorax.

Among the patients with small pneumothorax, 16 (28.33%) were managed through observation alone, 2 (3.33%) required needle aspiration, 15 (25%) required pleural catheter insertion, and 26 (44.06%) underwent surgical intervention for management. Out of 187 patients with large pneumothorax, 16 (8.6%) were managed through observation, 7 (3.76%) required needle aspiration, 73 (38.1%) required pleural catheter insertion, and 91 (48.6%) underwent surgery.

During the 12-month follow-up, 58 patients were lost to follow-up and 5 patients (5/188; 2.66%) presented with a recurrence of PSP. Out of 108 patients who underwent VATS, 2 (1.85%) had a recurrence of PSP.

Conclusion: PSP is more common in males than in females, with a tendency for younger age onset. The recurrence rate of PSP in our study was 2.66%. Furthermore, the recurrence rate in our patients who underwent VATS was 1.85%. Prospective studies are warranted to compare the success rates of different treatment interventions.

An attempt was made to correlate mechanical and tribological properties of Zn-40Al-2Cu-2Si alloy and the relationships between these properties were determined by linear regression analysis. The relationships between mechanical and tribological properties of this alloy were observed to be expressed by linear or simple straight-line equations. These relationships showed that as the hardness and the tensile strength of the alloy increase the friction coefficient, working temperature, and wear volume of it decrease but its average surface roughness increases. These observations were explained in terms of microstructure and mechanical properties of the alloy, adhesion theory of friction and the Archard wear law.

Протягом багатьох століть одним із провідних гравців у Чорноморському регіоні була Османська Імперія, а згодом і Турецька Республіка. Розташована на південному узбережжі Чорного моря, ця країна має значний вплив на політичні та економічні процеси регіону. В основі такого впливу є як порівняно численне населення (84,7 млн), так і розміри економіки (номінальний ВВП Турецької Республіки в 2021 р. – 815 млрд дол. США). За цими двома показниками Туреччина стала 19-ою країною у світі. Крім того, Туреччина, за підсумками 2021 р., була 30-ою країною у світі по експорту товарів та 22-ою – по імпорту товарів. Сукупність зазначених факторів робить Туреччину привабливим ринком для багатьох країн, насамперед експортерів сільськогосподарської продукції (до яких передусім належить і Україна), навіть попри економічні складнощі, з якими країна зіткнулась у 2022 р. Ще одним вагомим фактором, який сприятиме стратегічному партнерству України та Турецької Республіки, є перспективи повоєнного відновлення України та роль Туреччини у цьому процесі. Крім того, у період після завершення бойових дій неодмінно виникнуть вагомі зміни глобального безпекового середовища та економічної ситуації у світі загалом, та Чорноморському регіоні зокрема. Нові геополітичні виклики для обох держав як Турецької Республіки, так і України, створюють вікно можливостей щодо перспективи українсько-турецьких відносин, яким Україна має повною мірою скористатися.
TOXICITY STUDY OF URENA LOBATA USING ALLIUM SATIVUM: A NEW EUKARYOTIC BIOMONITORING TEST SYSTEM
Authors: Islam Muhammad Torequl
Published: November 2022

Urena lobata (L.) has diverse biological activities. A recent study suggests that its leaf extract exerts acute toxicity on three different phases of Zebra fish, where the authors calculated the median lethal concentration (LC50) value ranges between 2,548 and 8,748 g/L. This study aims to re-check its toxic effects on a new eukaryotic test model named the Allium sativum toxicity test model. For this, the ethanolic leaf extract of Urena lobata (ELEUL) was tested at 2, 4, 8, 16, and 32 mg/mL on the cloves of A. sativum at 24, 48, and 72 h exposure times (ET) using copper sulphate (CuSO4) as a reference standard. Manual observation of root number and length profiles was considered in this study. The results suggest that ELEUL significantly (p< 0.05) and concentration-dependently reduced the number and length of roots of the test system in comparison to the control group. However, the ELEUL exerted more toxic effects at 72 h ET on the test system, and it showed an adaptive capacity at 48 h inspect of 24 h ET. The LC50 value was obtained between 4 and 8 mg/mL. Taken together, the ELEUL exerted toxic effects on the root meristems of A. sativum cloves, and this new model was sensitive like other popularly used toxicogenetic biomonitoring systems, like the A. cepa test model. Therefore, A. sativum might be another hopeful plant-based toxicogenetic test model.

Microbial resistance to antibiotics has become a global threat that interferes with the interaction among humans, the environment, and microbes. Our study sought to detect antibiotic-resistant bacteria in light of the growing interest in using antibiotics in the poultry sector. We collected 24 poultry liter samples from 04 different upazilas of Khulna district (Batiaghata, Dumuria, Paikgachha and Koyra). Initially, 09 bacterial isolates were selected and among them, 77.78% bacteria were found gram positive. Subsequently, to characterize these bacteria, a toal of 10 biochemical tests (methyl red test, MacConkey agar test, indole test, catalase test, triple sugar iron test, mannitol salt agar test, oxidase test, Voges-Proskauer test, citrate test and nitrate test) were carried out in this experiment. Moreover, our study also isolated and amplified bacterial DNA for Sanger sequencing and finally disclosed 09 different antibiotic resistant bacterial species, namely Priestia aryabhattai, Bacillus cereus, Priestia megaterium, Lysinibacillus macrolides, Rossellomorea aquimaris, Mammaliicoccus sciuri, Bacillus wiedmannii, Escherichia coli and Citrobacter freundii. Further, disk diffusion assays were performed following CLSI guidelines and it unveiled the susceptibility and resistant properties of isolates against commonly used 08 antibiotics (penicillin 10U, tetracycline 20µg, nitrofuran 300µg, clindamycin 2µg, azithromycin 15µg, quinolones 5µg, tetracycline 30µg and penicillin 30µg) in poultry farms. All of the bacterial isolates were found resistant to at least one of the antibiotics except C. freundii (isolate 9). Most of the isolates (66.67%) were resistant to nitrofuran, whereas all of them were susceptible to penicillin. Lastly, this study also made an effort to understand the evolutionary relationships of the identified species through a phylogenetic tree. Thus, the findings of this study will help farmers and common people to better understand the risk of developing antibiotic-resistant bacteria as a result of excessive antibiotic usage.

Published: November 2022

Una prueba genética para distinguir si dos mutaciones génicas ocurren en el mismo locus funcional, así como establecer sus límites es la llamada prueba de complementación, ampliamente empleada en genética microbiana, el mismo principio se utiliza en agronomía y se conoce como dialelo. En genética de poblaciones y en particular en poblaciones de Drosophila se usa el término prueba de alelismo y es empleada fundamentalmente para determinar distancias genéticas y persistencia de genes en poblaciones naturales y experimentales en las que generalmente se hace para genes letales en condición heterocigota. Así nos propusimos hacer un análisis de éste tipo para genes letales portados en el segundo cromosoma de D. melanogaster extraídos previamente de una población natural originaria de una localidad en la Colonia del Valle, Ciudad de México. La prueba consistió en cruzar cada cepa portadora de un gen letal contra todas las demás. Un total de 50 cepas fueron sometidas a dicha manipulación correspondiendo así a 1225 cruzas individuales. Como resultado se obtuvieron 45 cruzas alélicas, distribuidas en 28 sencillas, nueve dobles de las cuales dos comparten con otro gen simulando una tripleta y por último una cruza triple. Finalmente la tasa de alelismo determinada fue de 3.67 % que no difiere mucho del promedio reportado por otros investigadores en estudios similares.
