Plataforma Uhle : enterrando y desenterrando muertos
Authors: Gutiérrez Belkys
Published: April 2023

Este artículo presenta las evidencias contextuales de la ceremonia del entierro y la manipulación ritual post-entierro de tumbas mochica registradas en la Plataforma Uhle, ubicada en el sitio Huacas de Moche. De un total de veinte tumbas de las fases I a V, diez siguieron esa ceremonia y ritual en el marco ideológico de una compleja práctica funeraria. Con esta muestra —aunque limitada—, intentamos comprender el carácter y la naturaleza de esas actividades celebradas durante el entierro de personajes de la elite mochica. Al mismo tiempo, presentamos por primera vez un conjunto de contextos funerarios con fenómenos parecidos de manipulación de cadáveres que provienen de una estructura arquitectónica de segundo nivel del principal centro mochica en el valle de Moche. Esta práctica ceremonial de manipulación ritual post-entierro es de amplia vigencia temporal y espacial. Así, la «alteración» de las tumbas no fue siempre obra del saqueo moderno sino de eventos rituales cíclicos relacionados, principalmente, con el fenómeno El NiñoOscilación del Sur, y debió asociarse a complejas ceremonias de sacrificios humanos

Impact of COVID-19 pandemic on elementary school children’s sleep hygiene
Authors: Luma Nita Beluli
Published: April 2023

The effect on sleep in elementary school-age, healthy children during the pandemic has been studied in various online survey studies with varied conclusions. However, no research study has been conducted in North Macedonia to examine the impact of the pandemic on the prevalence of sleep problems among elementary school-age children. Therefore, the present study is focused on exploring sleep patterns, sleep disturbances, and other associated factors during the COVID-19 pandemic outbreak in elementary school children.   Approximately 85 respondents were surveyed from a public elementary school in North Macedonia. The Children Sleep Habits Questionnaire was used to assess children's sleep habits. From the research, we were able to conclude that children aged 7-8, are more prone to experiencing few sleep subscales that relate to common sleep problems such as bedtime resistance, sleep anxiety, night waking, and parasomnia while children at aged 10-11 would perform more sleep onset delays than younger ones.
Keywords: children's mental health, sleep patterns, sleep health, sleep disruptions, COVID-19.

Advances in pancreas surgery: robotic pancreaticoduodenectomy
Authors: Riachi Mansour E. , Hewitt D. Brock
Published: April 2023

Surgeon technical improvements made in the 1980s significantly decreased the morbidity and mortality associated with pancreaticoduodenectomy (PD). While minimally invasive surgery (MIS) is now the standard surgical approach for many benign and malignant pathologies, the technical complexity associated with PD presents many challenges to MIS adoption. However, advancements in robotic technology have done much to ameliorate mechanical impediments. Compared to laparoscopic surgery, the robotic platform provides surgeons with enhanced visualization, greater degrees of freedom and range of motion, tremor elimination, and superior ergonomic positioning. Although cost and availability concerns persist, training programs have increasingly incorporated robotic curricula, boosting the prevalence of robotic procedures, including robotic PD (RPD). While prospective data are limited, studies evaluating RPD demonstrate safety, equivalent short-term oncological outcomes, and longer operating times compared to open PD. Furthermore, exciting avenues exist for the future of RPD, ranging from continued instrument innovations to AI-enhanced adjuncts. Robotics has the potential to improve PD for patients and surgeons alike; however, further evaluation of oncologic and surgical outcomes requires well-powered, randomized, prospective trials to confirm the results of earlier retrospective studies, given the significant biases present. In this article, we review the progression of minimally invasive PD, present outcomes from studies evaluating RPD, and discuss areas of innovation for RPD.

Backgrounds: It has been shown that COVID-19 can cause symptoms and diseases such as insomnia, depression, and anxiety. This study aimed to describe prevalence of feeling anxious or depressive among COVID-19 patients in six months of follow-up time and its association with baseline independent factors.

Materials and Methods: This prospective cohort study included patients aged ≥18 years who tested positive for SARS-CoV-2 at Dokuz Eylul University Hospital, Turkey between November 1, 2020 and May 31, 2021. Participants were interviewed by telephone calls on the 1st, 3rd and 6th months after diagnosis. The dependent variable of the study was self-reported moderate or severe anxiety or depression based on EQ-5D-3L general quality of life scale. Generalized estimating equations were used to identify the factors associated with feeling anxious and depressive after SARS-CoV-2 infection.

Results: In total 5446 patients agreed to participate in the study. Frequency of feeling anxious or depressive at the 1st, 3rd and 6th months after diagnosis were 18.5%, 17.9% and 15.4%, respectively. Older age (≥65 years; odds ratio-OR:1.17, 95% confidence interval-CI: 0.95-1.44), female gender (OR:1.76 (1.58-1.96)), bad economic status (OR: 1.62 (1.34-1.97)), having more symptoms (4-5, OR:1.48 (1.21-1.81); ≥5, OR:1.65 (1.35-2.01)), having more underlying health conditions (1-2, OR:1.35 (1.19-1.54); ≥3: OR:1.50 (1.13-1.99)), intensive care unit admission (OR: 2.58 (1.70-3.90)) were associated with self-reported anxiety and depression.

Conclusion: Feelings of anxiety and depression are common in COVID-19 patients and may persist in the long term. Anxiety and depression were associated with gender, economic status and disease severity. Determination of vulnerable groups for anxiety and depression after COVID-19 can be helpful for early diagnosis and initiation of mental care services.
CHANGES IN THE PERCEPTION OF TELEMATICS TECHNOLOGY BY ROAD TRANSPORT COMPANIES: AN EMPIRICAL ANALYSIS IN 2020-21
Authors: ZALEWSKI Wojciech , OSIŃSKA Magdalena , ŻUREK Mirosława
Published: April 2023

We present a novel study concerning the attitudes of road transport enterprises towards a broad application of telematics in operational management in road transportation. The study aims to assess telematics application in road transport and its changes over time while showing the factors most likely to determine the systems’ use. Unobserved categories defined in the technology acceptance model (TAM) are adjusted to measure perceived usefulness, perceived ease of use, and attitudes toward using telematics systems by road transport managers. The study is based on 323 transport enterprises analyzed in two waves in 2020 and 2021. The use of two different time points is motivated by an observed increase in the digitalization of transport documents caused by the COVID-19 pandemic. The empirical findings support the TAM’s usefulness in evaluating IT in transport business management. The findings also reveal that the significantly increased telematics use in 2020 was observed while it was endured. The results are checked for robustness and used for simulations. The study compares managers’ behaviors over time and simulates the effect of individual (observed) variables on unobserved TAM categories.
A SELECTION ANALYSIS OF SOLUTIONS FOR TEMPORARY TRAM TRAFFIC ORGANISATION EMPLOYED IN WROCLAW
Authors: SKIBA Magdalena
Published: April 2023

Urban transport plays a massive role in the proper functioning of cities [1, 2]. Prioritisation of public transport [3] is an attempt to fight growing traffic congestion, which has a noticeable impact on people’s comfort of living, especially in large cities [4-6]. Shaping the road environment to improve the quality of functioning of public transport means that the management of urban infrastructure cannot cause difficulties. The continuous execution of construction works in Wroclaw has forced the ordering party to introduce temporary, and often complicated, traffic organisation solutions. The primary goal is to ensure the most efficiency for public transport users while maintaining the smoothness of private transport. This article presents solutions to temporary tram traffic organisation used in Wroclaw. The frequency and effects of the applied solutions were analysed using examples of completed and planned tram investments in Wroclaw. The reasons for the applied solutions and possible directions for further analyses were considered.

Published: April 2023

Actions related to the improvement of the safety of disabled road users have multiple levels and are burdened with problems related to the collection and proper analysis of road incidents. A meta-analysis of databases could provide a better understanding of the causes of these events and prevent them in the future. Currently, residual information on participants of road accidents can be found in the Accident and Collision Record System; the data are analyzed by the Polish Road Traffic Observatory and submitted to the International Road Traffic and Accident Database and the Community Road Accident Database. In connection with the above, an article was prepared containing a propaedeutic review of research materials to date, as well as domestic and foreign databases constituting the diagnostics of the research area. An international literature search was also conducted on accidents involving people with disabilities. The findings indicate the need to collect and expand information about disabled participants of road incidents, fill this gap in databases, and systematize them as the starting material for the development of remedial actions.

Published: April 2023

Equality and incomparability multi-label ranking have not been introduced to learning before. This paper proposes new native ranker neural network to address the problem of multi-label ranking including incomparable preference orders using a new activation and error functions and new architecture. Preference Neural Network PNN solves the multi-label ranking problem, where labels may have indifference preference orders or subgroups which are equally ranked. PNN is a nondeep, multiple-value neuron, single middle layer and one or more output layers network. PNN uses a novel positive smooth staircase (PSS) or smooth staircase (SS) activation function and represents preference orders and Spearman ranking correlation as objective functions. It is introduced in two types, Type A is traditional NN architecture and Type B uses expanding architecture by introducing new type of hidden neuron has multiple activation function in middle layer and duplicated output layers to reinforce the ranking by increasing the number of weights. PNN accepts single data instance as inputs and output neurons represent the number of labels and output value represents the preference value. PNN is evaluated using a new preference mining data set that contains repeated label values which have not experimented on before. SS and PS speed-up the learning and PNN outperforms five previously proposed methods for strict label ranking in terms of accurate results with high computational efficiency.

Published: April 2023

Effortful control (EC) describes individual differences in self-regulation, with a strong attentional basis. Moreover, during early childhood EC has a central role on children’s socio-emotional adjustment and academic achievement. The aim of the current study was to predict the development of EC at 36 months of age from early attentional and environmental measures taken in infancy using a machine learning approach. A sample of 75 infants participated in a longitudinal study running different waves of data collection at 6, 9 and 36 months of age. Attentional tasks were administered at 6 months of age and two additional measures were collected at 9 months of age. Parents reported household environment variables during wave 1, and their child’s EC at 36 months. A machine -learning algorithm was implemented to identify children with low EC scores at 36 months of age. An “attention only” model showed greater predictive sensitivity than the “environmental only” model. However, a model including both attentional and environmental variables was able to classify the groups (Low-EC vs Average-to-High EC) with 100% accuracy. Sensitivity analyses indicate that socio-economic variables together with attention control processes at 6-months, and self-restraint capacity at 9-months, are the most important predictors of EC. Results suggest a foundational role of executive attention processes in the development of EC in complex interaction with household environment and provide a new tool to identify early markers of socio-emotional regulation development.
The Roles of Ral-Interacting Protein 76 and Vascular Endothelial Growth Factor in the Ovarian Corpus Luteum and Tumor Microenvironment
Authors: Min Tae-Hee , Lee Seunghyung
Published: April 2023

Ral-interacting protein 76 (RLIP76) is a potential factor with vascular endothelial growth factor (VEGF) in the corpus luteum and tumor angiogenesis. RLIP76, VEGF, and hypoxia-inducible factor-1 (HIF-1) are proteins that activate angiogenic functions in tumor and endothelial cells. RLIP76 is a main factor in tumor growth, and VEGF is a major endothelial cell protein for angiogenesis. Also, RLIP76 regulates a small GTPase (R-Ras, oncogene) in cell survival, spreading, and migration. HIF-1 is important in the corpus luteum, tumor angiogenesis, and tumor growth. VEGF and HIF-1 regulate the angiogenic function of RLIP76, and RLIP76 controls vascular growth in endothelial and tumor cells. RLIP76, R-Ras, VEGF, and HIF-1 may be useful in the research of corpus luteum and cancer therapy and the study of mechanisms of tumor angiogenesis. This review will help to elucidate the roles of RLIP76/R-Ras and VEGF via HIF-1 in corpus luteum and tumor angiogenesis, tumorigenesis, and the specific regulation of RLIP76 in luteal, tumor, and endothelial cells. Thus, we reviewed the angiogenesis of the corpus luteum and tumor in the ovarian and tumor microenvironment.
The Plagiochilins From Liverworts Plagiochila: Binding to α-Tubulin and Drug Design Perspectives
Authors: Bailly Christian , VERGOTEN Gérard
Published: April 2023

Among bryophytes, the Plagiochila genus represents a large group of leafy liverworts, with over 500 species. Plagiochilins A-to-X are sesquiterpenoids isolated from Plagiochila species. The lead compound plagiochilin A (Plg-A), endowed with anticancer and anti-parasitic properties, has been characterized as a potent mitosis inhibitor, acting selectively at the late stage of cytokinesis termed abscission. The compound perturbs the dynamic of microtubules, blocking cell cycle progression and triggering the death of malignant cells. Based on the compound mechanism of action and the analogy with other natural products bearing a dihydro-pyrone moiety, we postulated that Plg-A could bind to the pironetin site of α-tubulin. A molecular docking analysis has been performed to compare binding of all 24 plagiochilins to α-tubulin and to establish structure-binding relationships. The identification of Plg-E and Plg-G as the best binders in the series pointed out to the importance of the C13-OH or C=O group for α-tubulin recognition. This observation led to the testing of the natural product ester plagiochilin A-15-yl n-octanoate and the corresponding alcohol (Plg-OH), both identified as robust α-tubulin binders. The study provides a rational to explain potentially the mechanism of action of Plg-A and to guide the design of new derivatives.

Published: April 2023

Mobile robots can perform tasks on the move, including exploring terrain, discovering landmark features or moving a load from one place to another. This group of robots is characterized by a certain level of intelligence allowing making decisions and responding to stimuli received from the environment. As part of Industry 5.0, such mobile robots and humans are expected to co-exist and work together in a shared environment to make human work less tiring, quicker, and safer. This can only be realized when clean, dense, and economical energy sources are available. The aim of the study is to analyze the state of the art and to identify the most important directions for future developments in robotic power systems based mainly on batteries. The efficiency and performance of the battery depends on the design using different materials. Work environments and performance requirements are considered in this systematic review to classify solutions that help developers choose the best suited power system for specific application. Indirectly, the aim of the work is to generate discussion within the scientific and engineering community. A narrative review of publications from six major bibliographic databases according to preset inclusion criteria was combined with a critical analysis of current and future technologies. The main findings of the review allow answering question what is the role of modern power source technologies, artificial intelligence and ground-breaking research work in global policies related to energy saving, green policies, and sustainable development. The main opportunities and threats are discussed, and a brief feasibility analysis is carried out. Novelty of the article relates not only to the analysis of technologies, but also to approaches and their use under conditions of limited resource availability, when resource usage must be minimized. The article provides an overview of batteries, their specifications, classifications, and their advantages and disadvantages. In addition, we propose: (1) an algorithm for selecting main energy source for robot application, and (2) an algorithm for selecting electrical system power supply. Current mobile robot batteries are, in most cases, their biggest limitation. Progress in batteries development is too slow to catch up with the demand for robot autonomy and range requirements, limiting the development of mobile robots. Further intensive research and implementation work is needed to avoid years of delay in this area.
Study on the Ecology, Biology and Ethology of the Invasive Species Corythucha arcuata Say, 1832 (Heteroptera: Tingidae), a Danger to Quercus sp. in the Climatic Conditions of the City of Sibiu, Romania

Published: April 2023

This scientific paper examines the impact of climate change on the spread and survival of the invasive species Corythucha arcuata (Oak Lace Bug, or OLB) in Romania. The OLB is native to the Eastern USA and Canada, and in its native habitat, it coexists with minimal impact to the preferred host plant species Quercus. However, in Europe, the OLB in high-density causes early defoliation, slowing tree growth and it leads to the death of trees. As Quercus is a keystone species, the impact of the OLB on European forests is significant. This paper aims to address several gaps in knowledge about the OLB by presenting findings from a study conducted by the Lucian Blaga University of Sibiu (ULBS) in Romania. The study identified the species ‘chronology of spread, ecology, ethology, and biology of the species, in addition to foliage classification to determine the extent of attack. The study found a direct link between temperature and speed of the generational lifecycle. The findings support the thesis that climate change is enabling the healthy, rapid density growth of OLB, which is a danger to the Quercus sp. Further research is needed in the area of the thermal tolerance of the OLB, and the research conducted by the ULBS represents the first documented research into the thermal constant of the insect. The paper concludes that further research must be in the direction to understand how and where these insects survive during winter to find future management measures and identify chemical or biological methods as solutions to eradicate and stop the expansion of the invasion of the OLB, and the potential consequences for the Quercus sp.
An Enhanced Path Planner for Electric Vehicles considering User Defined Time Windows and Preferences
Authors: Cubillos Maximiliano , Dell'Amico Mauro , Jabali Ola , Malucelli Federico , Tresoldi Emanuele
Published: April 2023

A number of decision support tools facilitating the use of Electric Vehicles (EVs) have been recently developed. Due to the EVs’ limited autonomy, routing and path planning are the main challenges treated in such tools. Specifically, determining at which Charging Stations (CSs) to stop, and how much the EV should charge at them is complex. This complexity is further compounded by the fact that charging times depend on the CS technology, the EV characteristics, and follow a nonlinear function. Considering these factors, we propose a path planning methodology for EVs with user preferences, where charging is performed at public CSs. To achieve this, we introduce the Electric Vehicle Shortest Path Problem with time windows and user preferences (EVSPPWP) and propose an efficient solution algorithm for it. Given an origin and a destination, the algorithm prioritizes CSs close to Points of Interest (POIs) that match user inputted preferences, and user-defined time windows are considered for activities such as lunch and spending the night at hotels. The algorithm produces flexible solutions by considering clusters of charging points (CPs) as separate CSs. Furthermore, the algorithm yields resilient paths by ensuring that recommended paths have a minimum number of CSs in their vicinity. The main contributions of our methodology are: modeling user-defined time windows, including user-defined weights for different POI categories, creating CSs based on clusters of CPs with sufficient proximity, using resilient paths, and proposing an efficient algorithm for solving the EVSPPWP. To facilitate the use of our methodology, the algorithm was integrated into a web interface. We illustrate the use of the web interface, giving usage examples and comparing different settings.

Published: April 2023

The COVID-19 pandemic has not only affected public health but has also significantly impacted the economy. Bandung, a bustling city in Indonesia serving as a satellite to the capital, has been hit hard due to its high population density, mobility, and reliance on the tourism, trade, and transportation sectors. Using a Computable General Equilibrium (CGE) model developed at the inter-regional level of Indonesia, this study investigates the microeconomic indicators of several economic activities in Bandung to assess the impact of the pandemic. Additionally, the study examines the role of private sector actors in contributing to the sustainable recovery efforts toward achieving Sustainable Development Goals (SDGs) amidst the pandemic. The findings reveal that Bandung's transportation, accommodation, food and beverage, water supply, and trade sectors experienced a significant decline in economic activity. However, there was a gradual recovery with increased economic activity between 2019 and 2021. Private sector actors and the health sector were the main drivers of economic recovery, with other sectors also contributing to the efforts.

Abstract-, This research is an ex-post facto descriptive study, which aims to determine: a) the results of the safety relay coordination settings (OCR and GFR) and b) the working sequence and operating time of the safety relay when a disturbance occurs in the electrical system of PT. Rekind Daya Mamuju. Electrical system data obtained in the form of Single Line Diagram of PLTU Mamuju 2x25 MW, protection equipment data, and safety relay coordination data which are then processed and analyzed using the ETAP 12.6 program. The results showed that on the OCR inverse time curve the secondary side of the 0.4 kV transformer is set with a pickup current of 0.45 s, the primary side relay of the transformer is 6.3 kV 0.25 s and the relay is connected between unit I and unit II. 0.84 s. The GFR setting value for the definite time curve for the secondary side of the pickup current is 0.4 s, and the relay on the primary side is 0.2 s. The working time interval of the relay to break the disturbance is 0.3 s. Coordination of safety relays for PLTU Mamuju unit I and Unit II has worked well, with no overlapping or miss-coordination curve plot values. The sequence of work and the time of operation of the relay when a disturbance occurs is in the order of the simulation results with the coordinated setting values.

Early life-cycle prediction of reliability
Authors: Buchanan Randy , Rinaudo Christina , Gallarno George , Lagarde M.
Published: April 2023

The intent of this project is to investigate a variety of approaches for the development of a basic model for the early life-cycle prediction of reliability (pre-Milestone A). The United States Department of Defense (DoD) currently utilizes an acquisition framework in which system development advances through a series of checkpoints known as milestones. Each milestone represents a decision point, with Milestone A being the earliest in the life cycle. At Milestone A, also known as the risk-reduction decision, the DoD evaluates design concepts while also committing funds to the maturation of technologies in an effort to mitigate future risks. Typically, little is known about the particular system to be developed at this point in the acquisition life cycle, but DoD regulations require program man-agers to submit system reliability information (OUSD[A&S] 2015). Traditional reliability predictions, however, require extensive knowledge of the system of interest to produce accurate results. This level of knowledge is unavailable at or before Milestone A, there-fore, there is a need to create models and methodologies for the prediction of system reliability. This report provides an overview of a variety of methods investigated to improve the prediction of early life cycle reliability.

Abstract: Aplastic Anemia (AA) incidence is threefold higher in Asia compared to the western world. It is associated with pancytopenia that is induced by impaired bone marrow function. Cytopenias of at least two lineages are required for the diagnosis. Symptoms include pallor, weakness, fever, frequent infections, bruises, petechiae, and mucosal bleeding. Bone Marrow Transplant (BMT) and immunosuppressive therapy are the treatment options. Patients with Severe Aplastic Anemia (SAA) are susceptible to developing malignancies like acute myeloid leukemia (AML) or Myelodysplastic Syndrome (MDS). In this report, we present a case of SAA who transformed to AML/MDS. 5 years of post- Anti-Thymocyte Globulin (ATG), she acquired monosomy 7, RUNX1 & SETBP1 gene mutations. RUNX1 and SETBP1 mutations are correlated with poor overall survival and are predicted to have a lack of response from hypo-methylating agents. As the aspect of somatic mutation is complex and still not fully understood, it should be cautiously analyzed along with morphologic and cytogenetic results.

Published: April 2023

Fifty-Four paddy samples, 45 soil samples, and nine irrigation water samples of some paddy fields at Alfurat Alawsat Area, Iraq were collected to investigate the microbial quality including total count bacteria (TCB), molds and yeast, total coliform (TC), and E. coli bacteria. Paddy samples were processed at the laboratory level to produce rice at 32 and 36 whiteness, and the microbial quality of the produced rice was conducted too. The results showed that all irrigation water samples were overpassed the FDA limit for E. coli. All paddy samples were exceeded the good limit of TCB, but no sample exceeded the acceptable limit. Most paddy samples were exceeded the FDA limit for molds and yeast, and few paddy samples exceeded the total coliform limit. The milling process reduced microbial levels for some samples, while the effect was undetectable for other samples. Ten rice samples at 32 whiteness and eight rice samples at 36 whiteness out of 13 paddy samples overpassed FDA and Iraqi Quality Standardization (IQS) for molds and yeast. All produced rice at both whiteness levels was exceeded the total coliform of IQS, while only six and three samples out of 13 rice samples at 32 and 36 whiteness respectively overpassed the FDA limit. In conclusion, paddy samples taken from Alfurat Alawsat fields were overpassed some microbial levels from fields without the effect of storage or milling processing. Irrigation water was probably the main source of fields’ contamination, therefore, the paddy fields need to be monitored and controlled in terms of their microbial contamination.

Diabetic kidney disease is an illness of the glomerulus that interferes with the glomerular filtration barrier (GFB), which is worked to enable kidney to selective purification of water and solutes in addition to limiting the movement of large macromolecules such as albumin. In the glomerular endothelium, mesangial cells, foot cells, and the brush border of the proximal tubules, ACE-2 is expressed and that the kidneys represent the highest-expressing region of this enzyme. Thus, the current study aimed to evaluate ACE-2 level in this case compared to healthy condition. The study Conducted with 120 male and female ranging in age (30-65) years old. Ninety patients with type 2 diabetes subdivided into three groups on the basis of ACR criteria including normoalbuminuria, microalbuminuria, macroalbuminuria (30 patients for each group) and 30 healthy people served as the control group, all visited Baghdad Teaching Hospital / Medical City and Al-Yarmouk Teaching Hospital, at the period between December 2021 and May 2022.  ACE-2 levels were determined using the ELISA technique. Urea results showed significant differences between diabetic nephropathy in patient and control group in female cases but no significant differences in male patients with diabetic nephropathy and control group. Similar results were obtained in K ion. Also the results revealed significant differences in Na ion, ACR, eGFR, Urea, FBS, creatinine between diabetic nephropathy groups and healthy group.ACE-2 represents a good marker for early prediction in diabetic nephropathy case. ROC data analysis support the importance of ACE-2 in diagnosis of the studied disease case.

Published: April 2023

Polycystic ovary syndrome (PCOS) is the most endocrine problem in women of regenerative age. PCOS women typically belong to an age and sex group which is at higher risk for severe coronavirus disease (COVID-19). COVID-19 targets cells through angiotensin-converting enzyme 2 (ACE2) receptor presents on cells in veins, lungs, heart, digestion tracts, and kidneys. Renin-Angiotensin System (RAS) over activity has likewise been described in metabolic disorders; type 2 diabetes mellitus (T2DM), and conditions shared by women with polycystic ovary condition. The point of this study is to know the job of renin and ACE2 in PCOS and coronavirus and its relationship with hormones and other metabolic parameters related. The study groups consist of 120 sample subjects consisting of 80 PCOS-women divided into two groups: - (40 PCOS-women infected with COVID-19 and 40 PCOS-women non-infected with COVID-19) and 40 healthy-women divided into two groups: - 20 women-COVID-19 infected, and 20 women non-COVID-19 infected, ranging in age from 15–40 years old.  Renin and ACE2, FBS, lipid profile, level of insulin, HOMA IR, FSH, LH, and testosterone, were measured for all participants. There was an increase in the levels of renin, ACE2, insulin, HOMA-IR, LH, LH / FSH ratio, and testosterone, except HDL and FSH were low when comparing PCOS patients groups with healthy groups. There was a decrease in renin and ACE2 in PCOS women infected with COVID-19 compared with PCOS women non-infection with COVID-19. Infection of COVID-19 and low ACE2 levels lead to respiratory damage and problem in reproductive in PCOS patients. Also, at the same time ACE2 high level in PCOS makes them more risk for coronavirus and is not involved in the cause of PCOS, however renin enzyme may be affected by BMI associated with PCOS.

Sweet pepper (Capsicum annuum L.) is an economically important vegetable crop. Wilt disease caused by Fusarium oxysporum f. sp. capsici is a specific pathogen that affects the pepper. Four isolates of F. oxysporum f. sp. capsici Fo3, Fo6, Fo7 and Fo8 were obtained from diseased pepper plants that were collected from different pepper fields in Baghdad. Fo6 isolate that has high pathogenicity to pepper seeds, Trichoderma harzianum (Th) was tested in vitro against F. oxysporum f. sp. capsici showed a high inhibition rate for the isolate Fo6, the concentration of chelated iron Fe-EDDHA 0.5% reduced the radial growth of Fo6 while did not affect the growth of Th. In pots experiment, the treatment Fo6+Th+Fe showed a significant reduction in the incidence and severity of root rot and wilt diseases. The treatment Th+Fe achieved a highly significant increase in fresh and dry root and vegetative weight 63.36, 130.56, 4.55 and 10.26g respectively, compared with control (without pathogenic) reaching 11.10, 54.83, 1.30 and 3.70g respectively. Moreover, in greenhouse the treatment Fo6+Th+Fe has reduced the incidence and severity of disease 3.33 and 1.67% respectively, and the treatment Th+Fe gave an increase in the total chlorophyll content 104 SPAD compared with the control 70.4 SPAD.

Beyond the Dams - Combatting Hydropower Over-reliance & Securing Pathways for a Low-carbon Future for Laos' Electricity Sector using OSeMOSYS (Open-Source Energy Modelling System)
Authors: Wong Sebastian
Published: April 2023

Since the onset of the millennium, Laos has seen exponential growth in the past decades, becoming one of the fastest growing economies of the 21st century. Much of its success owes to its emerging position as ‘the battery of Southeast Asia’ through the exportation of mostly hydropower. While this has brought about almost-universal praise as the beacon of ‘sustainable development’, the detractors of this notion are not without merit. A growing amount of evidence demonstrates that if Laos continues hydropower expansion in its current trajectory, a multitude of implications can stand to disenfranchise the most marginalised in Laos and beyond. Alongside this predicament, much of the world is seeking to set a net-zero CO2 emissions by 2050 in order to avoid the most extreme consequences of the climate crisis.
This report seeks to draw up potential pathways to both pressing issues through utilising OSeMOSYS (Open-Source Energy Modelling System), a long-term energy system modelling tool, to create seven scenarios that would provide insight into what pathways there are for the Lao electricity sector to wean its hydropower dependency and still be low-carbon in different capacities.
The modelling output suggests that a low-carbon future not overly-reliant on hydropower is highly feasible and five policy recommendations have transpired through drawing on common themes and key insights of the modelling output. They include the prioritisation and promotion of non-hydro RE, most namely biomass as it serves to replace coal within Laos’ generation mix, the encouragement of small-scale electricity production, transmission and distribution grid improvements and the establishment of an independent power sector regulator. Further research is encouraged to reflect the dynamic changes within RE technology development and improved upon datasets in order for increased accuracy, as well as analysis on a whole energy system level.
