Hydropower Planning in Combination with Batteries and Solar Energy

Battery storage is an important factor for power systems made up of renewable energy sources. Technologies for battery storage are crucial to accelerating the transition from fossil fuels to renewable energy. Between responding to electricity demand and using renewable energy sources, battery storage devices will become increasingly important. The aim of this study is to examine how battery storage affects a power system consisting of solar and hydroelectric energy and to draw conclusions about whether energy storage recommends a power system. The method involves designing a model of eight real cascade hydropower power plants and solving an optimization problem. This power system model is based on existing hydroelectric power plants powered by solar energy and batteries in the Turkish cities of Yozgat and Tokat. A case study with four different battery capacities in the system was carried out to assess the implications of energy storage in the power system. The stochastic nonlinear optimization problem was modeled for 72 h and solved with the MATLAB programming tool. The stochastic Quasi-Newton method performs very well in hybrid renewable problems arising from large-scale machine learning. When solar energy and batteries were added to the system, the maximum installed wind power was found to be 2 MW and 3.6 MW, respectively. In terms of profit and hydropower planning, a medium-proportion battery was found to be the most suitable. Increased variability in hydropower generation results from the installation of an energy storage system.
OCCURRENCES OF WHEAT CURL MITE ACERIA TOSICHELLA KEIFER 1969 (ERIOPHYIDAE) AND THE ASSOCIATED VIRUSES, (WSMV, HPWMoV, TriMV) IN IRAQ

This study was aimed to investigate the significant wheat yield losses in northern and central Iraq. The cause of these losses was examining the presence of wheat curl mite Aceria tosichella and three viruses vectored by this species – Wheat streak mosaic virus (WSMV), High Plains wheat mosaic virus (HPWMoV), and Triticum mosaic virus (TriMV). Mite specimens were collected from Erbil, Mosul, and Baghdad over three years (2020-2022) and identified using morphological characterization and DNA sequencing of the ITS region. Virus presence was determined using Double Antibody Sandwich-Enzyme-Linked Immunosorbent Assay (DAS-ELISA). Mites were identified conclusively as A. tosichella, providing the first record of this species in Iraq. All three viruses were found to be present, with WSMV having the largest presence as it was detected in 99.56%, then HPWMoV (79.5%) of mite colonies. This is the first record of HPWMoV anywhere in Eurasia besides Ukraine and its widespread presence in Iraq in all three sampled provinces. TriMV was detected only in Erbil. To date this virus has been recorded only in North America and its limited presence in Iraq. The confirmed presence of A. tosichella and three vectored-viruses in Iraq are all new records and critical information for reducing wheat yield losses in this country.
Deciphering Common Traits of Breast and Ovarian Cancer Stem Cells and Possible Therapeutic Approaches

Breast cancer (BC) and ovarian cancer (OC) are among the most common and deadly cancers affecting women worldwide. Both are complex diseases with marked heterogeneity. Despite the induction of screening programs that increase the frequency of earlier diagnosis of BC, at a stage when the cancer is more likely to respond to therapy, which does not exist for OC, more than 50% of both cancers are diagnosed at an advanced stage. Initial therapy can put the cancer into remission. However, recurrences occur frequently in both BC and OC, which are highly cancer-subtype dependent. Therapy resistance is mainly attributed to a rare subpopulation of cells, named cancer stem cells (CSC) or tumor-initiating cells, as they are capable of self-renewal, tumor initiation, and regrowth of tumor bulk. In this review, we will discuss the distinctive markers and signaling pathways that characterize CSC, their interactions with the tumor microenvironment, and the strategies they employ to evade immune surveillance. Our focus will be on identifying the common features of breast cancer stem cells (BCSC) and ovarian cancer stem cells (OCSC) and suggesting potential therapeutic approaches.
Effect of THI, NDF and rumination in milk production by Holstein cows

Objective: The aim of the present study was to evaluate the effect of the temperature-humidity index (THI), the content of neutral detergent fiber (NDF), and rumination rate (RR) on milk production in Holstein cows in a dairy farm located in Bajío de San José, Jalisco, Mexico. Design/methodology/approach: The THI is an indicator of the effect of the environmental climate can have on milk production, and likewise the nutritional content of forage is affected by weather conditions, such as the NDF is related with rumination activity of cows; increasing THI has shown a direct effect on milk production in cows. The HealthyCow 24 ® CSR remote equipment was used (SCR Engineers Ltd., Netanya, Israel), to monitor rumination, from a total registry of 284 cows with 2, 3, and 4 lactations distributed between August and December 2020 period, analyzing the NDF content from total mixed portion and monitoring the THI. Results: The results showed there was no effect of THI on milk production (p>0.05), despite having reached a THI score of 76, while NDF (p<0.05) and RR (p<0.001) affected milk production; an effect of THI on RR (p>0.05) was not found, and the NDF only had a trend (p<0.1). Limitations on study/implications: There were no limitations for the study. Findings/conclusions: According to the results obtained, the THI threshold should be reconsidered according to the resistance of the productively active cattle on dairy farms.
Effects of Leadership on Financial Performance of Deposit Taking Saccos in Meru County

The emergence of Savings and Credit Co-operative Societies has been hailed as one of highly captivating financial sector in the world as a result of offering an alternative to financial intermediary and economic growth. However, over and above all the poor financial performance of these SACCOs has been subject of concern and it’s hinged on inadequate corporate governance. As a result, the purpose of this research is to establish the influence of leadership on financial performance of deposit taking SACCOs in Meru County. In this study, Stakeholders theory has been chosen to guide the study. The population of interest in this study will comprise of 12 DT- SACCOs with a target population of 120 participants drawn from the 12 DT- SACCOs in Meru County, the study population will comprise of CEOs, Executive Board Members, and operational Managers of the SACCOs. The study will employ census and purposively sample all the120 to participate in the study. Structured questionnaires with a five-point non-comparative Likert scale will be used to collect primary data. Data collected will be both qualitative and quantitative and will be analyzed by descriptive and inferential statistics. Statistical Program for Social Sciences (SPSS) will be used to analyze the data. The findings were presented using tables, charts, percentages, tabulations, means and other measures of central tendency. Tables were used to summarize responses for further analysis and facilitate comparison. This generated quantitative reports through tabulations, percentages, and measures of central tendency. The findings of this study established a strong positive correlation between board composition and financial performance of SACCOs. Academic qualification and occupation had the highest influence on SACCO’s financial performance with r (33) = 0.851, p < 0.05 and r (33) = 0.845, p< 0.005 respectively. It was however noted that there was a weak positive correlation between gender and SACCO’s financial performance, r (33) = 0.432, p < 0.05. It was also established that there is a strong negative correlation between size of board and SACCO’s financial performance, r (33) = - 0.784, p < 0.05. This means that the fewer the board members the better the financial performance of SACCOs. Besides, a strong positive correlation between board leadership and SACCO’s financial performance was determined, r (33) = 0.812, p < 0.05. A strong positive correlation between transparency and accountability and SACCO’s financial performance, r (33) = 0.884, p < 0.05 existed. The coefficient of determination R square was 0.542 which implied that 54.2% of variation in the dependent variable is determined by the independent variables (predictors). It also means the goodness of fit test is fulfilled. This also means that all the factors (board composition, board size, leadership, transparency and disclosure) significantly predict financial performance of SACCOs, with transparency and accountability having the highest prediction (ß = 2.208).
Biochemical characterization of a psychrophilic and halotolerant α–carbonic anhydrase from a deep-sea bacterium, Photobacterium profundum

Prokaryotic α–carbonic anhydrases (α-CA) are metalloenzymes that catalyze the reversible hydration of CO2 to bicarbonate and proton. We had reported the first crystal structure of a pyschrohalophilic α–CA from a deep-sea bacterium, Photobacterium profundum SS9. In this manuscript, we report the first biochemical characterization of P. profundum α–CA (PprCA) which revealed several catalytic properties that are atypical for this class of CA's. Purified PprCA exhibited maximal catalytic activity at psychrophilic temperatures with substantial decrease in activity at mesophilic and thermophilic range. Similar to other α–CA's, Ppr9A showed peak activity at alkaline pH (pH 11), although, PprCA retained 88% of its activity even at acidic pH (pH 5). Exposing PprCA to varying concentrations of oxidizing and reducing agents revealed that N-terminal cysteine residues in PprCA may play a role in the structural stability of the enzyme. Although inefficient in CO2 hydration activity under mesophilic and thermophilic temperatures, PprCA exhibited salt-dependent thermotolerance and catalytic activity under extreme halophilic conditions. Similar to other well-characterized α–CA's, PprCA is also inhibited by monovalent anions even at low concentrations. Finally, we demonstrate that PprCA accelerates CO2 biomineralization to calcium carbonate under alkaline conditions.
Aortic Root Dilatation Measured by Cardiac Magnetic Resonance in Patients with Repaired Tetralogy of Fallot.

BACKGROUND Aortic root dilatation (AoD) frequently occurs following repaired tetralogy of Fallot (rTOF). The objective of this study was to assess aortic dimensions, investigate the prevalence of AoD, and identify predictors of AoD in rTOF patients. METHODS A cross-sectional retrospective study was conducted in repaired TOF patients from 2009 to 2020. Aortic root diameters were measured by cardiac magnetic resonance (CMR). Severe AoD of the aortic sinus (AoS) was defined as a Z-score (z) of >4, reflecting a mean percentile ≥99.99%. RESULTS Two hundred forty-eight patients, with a median age of 28.2 years (10.2-65.3 years), were included in the study. The median age at the time of repair was 6.6 years (0.8-40.5 years) and the median interval between the repair and CMR study was 18.9 years (2.0-54.8 years). The prevalence of severe AoD was found to be 35.2% when defined by an AoS z greater than 4 and 27.6% when defined by a AoS diameter ≥40 mm, respectively. A total of 101 patients (40.7%) had aortic regurgitation (AR), with 7 patients (2.8%) having moderate AR. Multivariate analysis revealed that severe AoD was only associated with the left ventricular end diastolic volume index (LVEDVi) and a longer duration after repair. The age at the time of repair for TOF was found not to be correlated with the development of AoD. CONCLUSIONS After repair of TOF, severe AoD was found to be prevalent, but no fatal complications were observed in our study. Mild AR was also commonly observed. Larger LVEDVi and a longer duration after repair were identified as factors associated with the development of severe AoD. Therefore, routine monitoring of AoD is recommended.
Human–Robot Interaction Evaluation-Based AAN Control for Upper Limb Rehabilitation Robots Driven by Series Elastic Actuators

Series elastic actuators (SEAs) have been the most popular compliant actuators as they possess a variety of advantages, such as high compliance, good backdrivability, and tolerance to shocks. They have been adopted by various rehabilitation robots to provide appropriate assistance with suitable compliance during human–robot interaction. For a multijoint SEA-driven rehabilitation robot, a big challenge is to develop an assist-as-needed (AAN) method without losing stability during uncertain physical human–robot interaction. For this purpose, this article proposes a human–robot interaction evaluation-based AAN method for upper limb rehabilitation robots driven by SEAs. First, in order to stabilize the SEA-level dynamics, singular perturbation theory is adopted to design a fast time-scale controller. Second, for the robot-level dynamics, an iterative learning algorithm is adopted for impedance adaption according to the task performance and human intention. The interaction force feedback is introduced for human–robot interaction evaluation, and the intensity of robotic assistance will be adjusted periodically according to the evaluation results. The stability of human–robot interaction is provided with the Lyapunov method. Finally, the proposed rehabilitation method is constructed and implemented on a two-degree-of-freedom SEA-driven robot. It handles the uncertain interaction in such a principle that correct movements will lead to less assistance for encouraging participation and incorrect movements will lead to more assistance for effective training. The proposed method adapts to the subject's intention and encourages higher participation by decreasing impedance learning strength and increasing allowable motion error. It can fit the participants with different motor capabilities and provide adaptive assistance when a specific trainee tries to change his/her participation during rehabilitation. The performance of the AAN method was validated with experimental studies involving healthy subjects.
The Role of Levosimendan Infusion in Improving Renal Function in Worsening Type II Cardio-Renal Syndrome

The cardio-renal syndrome (CRS) includes a variety of pathologic conditions (acute or chronic) where the primary failing organ can be either the heart or the kidney. We present three cases of heart failure (HF) patients hospitalized for acute decompensation, who presented a CRS type II rapidly worsening after high doses of furosemide infusion. METHODS: From June 2015 to March 2016 all patients admitted to our Department for chronic refractory heart failure (NYHA class IV), underwent a determination of BNP and other laboratory tests (creatinine, GFR, haemoglobin), echocardiogram, non-invasive cardiac output measurement and 6 min walking test. Patients underwent a single infusion of levosimendan in case of CRS type II, at 0.1 µg/kg/min for 24-36 hours. Clinical / laboratory evaluation was repeated 24 hours and 1 week after infusion of the drug. RESULTS: Patients treated with levosimendan allowed the reduction of loop diuretics dose, because of the restoration of renal function. Body weight and peripheral edema were progressively reduced, and cardiac output improved. At discharge, exercise capacity significantly improved, functional class proved to be in NYHA class II-III, renal function and neurohormonal assessment (BNP) ameliorated. At one-month follow-up the clinical conditions remained stable as well as the parameters of renal function and plasma BNP. CONCLUSION: This clinical experience demonstrated that one of most frequent and dangerous evolution of renal impairment (development of Acute Kidney Injury) might be improved by using a single dose of levosimendan, which has a proved effect in improving cardiac function and urine output.
Exploring the mechanism of action and efficacy of Shi-Pi-San in the treatment of ascites in cirrhosis based on intestinal microbiota

Objective: To investigate the mechanism of action and efficacy of Shi-Pi-San (SPS) in the treatment of cirrhotic ascites based on intestinal flora and to provide new ideas for clinical research. Methods: We searched PubMed, CNKI, Wanfang and Wipu Chinese journal databases to collect randomized controlled trials of SPS in the treatment of cirrhotic ascites, extracted relevant data, and summarized them to analyze the relationship between intestinal flora and cirrhotic ascites. Results: The disorder of intestinal flora can lead to cirrhotic ascites, and the treatment of cirrhotic ascites with SPS has good efficacy, and SPS has positive effects in improving the status of intestinal flora, increasing the abundance of flora and inhibiting the growth of pathogenic bacteria. Conclusion: SPS has good long-term efficacy in the treatment of cirrhotic ascites, but the side effects and dosage criteria have not been extensively studied in clinical practice.
Exercise motivation and body image in middle-aged women

Middle-aged women do various ways to get an ideal body posture, one of which is by exercising. This study aims to determine the relationship between motivation to exercise and body image of middle-aged women. This research is correlative quantitative research. Middle-aged women at Mahkota Gym Prabumulih, totaling 105 people, participated in this study. The sampling technique used in this study was purposive sampling with 3 characteristics: middle-aged women aged 35-50 years, weighing more than 50 kgs, and regularly attending gymnastics classes at least once a week. The collection technique used body image scales and exercise motivation. This study uses a simple linear regression test analysis technique. Based on the results of data analysis, there is an influence of exercise motivation on body image. The contribution value of exercise motivation with body image is 21.5%. There is still a 78.5% influence from other factors related to body image that is not involved in this study, so it can be concluded that there is a very significant influence between exercise motivation on body image in middle-aged women at Mahkota Gym Prabumulih
Poverty, Somatisation Tendency and Potency in Low-Income Adolescent Groups of India and Israel: Explorations from the Field

Poverty increases vulnerability towards somatisation and influences the sense of mastery and well-being. The present study on adolescents living in relative poverty in a high-income group country (Israel) and a low-middle-income group country (India) explored the nature of somatisation tendency (ST) and its relationship with potency and perception of poverty (PP). Potency, a buffer against stress-induced negative health effects, was hypothesized to be negatively related to ST and mediate the link between PP and ST. Purposive sampling was used to collect questionnaire-based data from community youth (12–16 years) of two metropolitan cities—Kolkata (India, N = 200) and Tel-Aviv (Israel, N = 208). The nature of ST, PP and potency was analysed using descriptive and inferential statistics and correlation-regression statistics and mediation analysis were used to understand the relationship among them. A clinically significant level of ST was reported by both Indian and Israeli youth experiencing 5–7 somatic symptoms on average. Potency was found to be a significant predictor of ST in both countries (p < 0.05) and emerged as a significant mediator (p < 0.001) in the PP and ST relationship among Indian adolescents. The present study highlights potency as a protective buffer in economically vulnerable community adolescents and re-establishes a high prevalence of ST among them, irrespective of their country’s global economic position.
Simultaneous dual derivation in word formation

Cet article explore la nature des categories morphologiques en examinant deux types d'adjectifs denominaux en anglais : «beared» et «friendly». Parfois ces adjectifs paraissent morphologiquement distincts et parfois pas : la comparaison «icy hand» et «icy road». La langue fournit deux manieres differentes de generer ces adjectifs : la transposition qui a pour effet d'alterer la categorie lexicale mais pas ses caracteristiques grammaticales, et la derivation fonctionnelle qui a un effet inverse. Cet article tente de montrer comment ces adjectifs peuvent derives simultanement de la transposition et de la derivation fonctionnelle
Neuroanatomical Localization of the Vestibular Cortex: A Case Report

Vertigo, a symptom of illusory movement, is caused by asymmetry of the vestibular system. The vestibular system consists of the vestibular labyrinth, cranial nerve VIII, brainstem vestibular nuclei, cerebellum, ocular motor nuclei, spinal cord, and less well-defined cerebral projections. In this day and age of artificial intelligence, machine learning, advanced imaging, and cutting-edge research in the field of neurology, the exact cortical control of vestibular function is still uncharted. A 45-year-old woman with a past medical history of labyrinthitis about 4.5 years ago (resolved) presented to hospital due to severe dizziness, emesis, and mild vertical diplopia for the past few days. Her symptom of dizziness i.e. room spinning was continuous without any postural component. MRI of the brain revealed a small stroke in the left hippocampal area, more specifically alveus of hippocampus. The patient was started on dual antiplatelet therapy and atorvastatin for secondary stroke prevention. Follow-up visit as an outpatient at one-month post hospital discharge was unremarkable without any recurrence of vertigo symptoms. We believe this may indicate that the limbic lobe has a much larger role in vestibular functioning than previously thought, and may control more vestibular operations than any other central nervous system area.
Managing small populations—using genetic data and trial translocations to help inform suitable conservation measures for the alpine blue-sowthistle (Cicerbita alpina) in Scotland

Habitat fragmentation is causing an increasing amount of species loss around the world and creates problems at the population level. Many species are left as only small and isolated populations, which are vulnerable to genetic erosion and inbreeding depression. Here we present a study on the alpine blue-sowthistle (Cicerbita alpina). Due to intensive grazing the species is very rare in Scotland, where it occurs at only four small, montane sites, has never been reported to reproduce and is in need of conservation interventions. As the species can grow clonally it is unknown how many individuals remain and whether populations are affected by genetic isolation. We (1) quantified genetic diversity, inbreeding and between-population differentiation in Scotland and Norway using 15 microsatellite loci, and (2) experimentally translocated plants to new sites. Genetic diversity in Scotland was low (H E: 0.35; Allelic Richness: 1.84; 4 sites) compared to Norway (H E: 0.52; Allelic Richness: 2.56; 5 sites). The transplants were able to grow at new sites and are therefore not restricted to steep, montane ledges. While grazing is likely to be the main factor preventing range expansion, long-term genetic isolation has possibly further lowered population viability. To avoid local extinction of this species, conservation translocations and genetic rescue might be appropriate conservation interventions, but this needs to be further tested in a controlled environment and away from wild sites to avoid potential risks of outbreeding depression.
