RESUMO: A verificação da uniformidade de aplicação de água em sistemas de irrigação localizada, constitui-se em uma ferramenta que promove o seu dimensionamento adequado, de maneira a resultar no melhor rendimento das culturas. Objetivou-se com este trabalho avaliar o desempenho, pelos coeficientes de uniformidade, de um sistema de irrigação por gotejamento, com diferentes comprimentos de linhas laterais, operando sob energia solar fotovoltaica. O trabalho constou do dimensionamento hidráulico para encontrar os comprimentos ideais de linhas laterais que possibilitassem menor variação de vazão por variações de pressões entre 5 e 15 mca, seguido dos testes de uniformidade CUC, CUD e CUE em duas situações (com e sem calibração da pressão do sistema no início da área em 10 mca). Conclui-se que ao se calibrar a pressão de serviço no início da área em 10 mca, em qualquer período do dia observado, a uniformidade de aplicação de água ficou acima de 90%, o que classifica o equipamento como excelente para os comprimentos de linha lateral de 30 a 60 metros.

PERFORMANCE OF DRIP IRRIGATION SYSTEM WITH SOLAR PHOTOVOLTAIC ENERGY

ABSTRACT: The verification of the uniformity of water application in localized irrigation systems is a tool that promotes its proper dimensioning, in order to result in the best crop yield. The objective of this work was to evaluate the performance, through uniformity coefficients, of a dripping irrigation system, with different lengths of lateral lines, operating under photovoltaic solar energy. The work consisted of the hydraulic dimensioning to find the ideal lengths of lateral lines that would allow less variation in flow due to pressure variations between 5 and 15 mca, followed by uniformity tests CUC, CUD and CUE in two situations (with and without system pressure calibration at the beginning of the area at 10 mca). It is concluded that when calibrating the service pressure at the beginning of the area at 10 mca, at any time of the day observed, the uniformity of water application was above 90%, which classifies the equipment as excellent for the line lengths from 30 to 60 meters.

Authors: Inayah Dinda Rifdayani , Priyanto Bambang , Rohadi Rohadi , Januarman Januarman 
Published: August 2024

Highlight:

Hyponatremia is a potentially life-threatening condition.
Refracter hyponatremia can be seen in patients with systemic infection who have undergone therapy.

ABSTRACT
Introduction: Hyponatremia is a condition in which the sodium serum level is below the normal range. This condition is most common in hospitalized patients receiving systemic infection therapy and can lead to worse outcomes, potentially life-threatening.Objective: This study aimed to summarize the incidence of refractory hyponatremia due to systemic infection therapy. Methods: This was a systematic literature search conducted in October 2023 on the online database PubMed regarding refractory hyponatremia due to systemic. The analysis excluded narrative reviews, non-English studies, and studies that only discussed transient hyponatremia or local infections. Results: A total of 10 case reports of 11 patients were included in the final analysis. The mean age of patients was 46.63 years (SD = 20.79 years), and 63.64% were male. Strongloides stercoralis hyperinfection was the most common cause of systemic infection (54%). It was followed by disseminated Varicella-zoster virus infection (28%), tuberculosis (9%), and systemic nocardiosis (9%). The most common cause of immune compromise is stem cell transplant recipients (28%), followed by miliary tuberculosis (18%). Up to 91% of cases are caused by the syndrome of inappropriate antidiuretic hormone (SIADH), which is the pathophysiology of hyponatremia. Conclusion: Most patients with systemic infections and refractory hyponatremia have conditions that encourage immune compromise. The treatment of systemic infections is a priority since they contribute to hyponatremia.

Published: August 2024

Highlight:

CPAP therapy is a medical treatment for individuals suffering from OSA, a condition that is frequently linked to cardiovascular disease and resistant hypertension.
Five studies clearly showed that combining CPAP therapy with standard medications had a big effect on the blood pressure of patients with both obstructive sleep apnea (OSA) and resistant hypertension.
Administering CPAP in conjunction with standard treatment, as per guidelines, has demonstrated the capability to lower both daytime and nighttime blood pressure in individuals affected by OSA and resistant hypertension.

ABSTRACT
Introduction: Obstructive sleep apnea (OSA) is an upper respiratory tract disorder that is often associated with cardiovascular diseases, one of which is resistant hypertension (RH). On the other side, Continuous Positive Airway Pressure (CPAP) is a medical treatment that is often used for patients with OSA and RH. Objective: This meta-analysis aimed to determine the effectiveness of CPAP in patients with OSA and resistant hypertension by measuring systolic and diastolic blood pressure at diurnal, nocturnal, and 24 hours. Methods: We conducted a systematic review using a PRISMA flowchart, utilizing sources such as PubMed, Scopus, Science Direct, and ClinicalTrials.gov with MeSH. We then reviewed these sources for quality studies using RoB2, and analyzed the data using the Revman website version. 5.4.Results: The five studies included in the analysis found that CPAP, while maintaining conventional drugs, significantly affected the blood pressure of patients with OSA and RH. The significant results were made clearer by obtaining data for nocturnal SBP pressure, mean -3.89 mmHg (95% CI: -7.03 to -0.76) with a p-value < 0.02, and then nocturnal DBP obtained a mean of -2.34 mmHg (95% CI: -4.70 to 0.02) with a p-value < 0.05. Meanwhile, the 24-hour results for SBP obtained a mean of -2.97 mmHg (95% CI: -5.88 to -0.06) with a p-value < 0.05, and the 24-hour results for DBP obtained a mean of -2.39 mmHg (95% CI: -4.62 to -0.16) with a p-value < 0.04. Conclusion: CPAP, while maintaining conventional treatment according to indications, can reduce 24-hour and nocturnal blood pressure in patients with OSA and resistant hypertension.

Published: August 2024

This study investigates the potential of utilizing hazelnut shells (HS) as an innovative filler in three-layer plywood technology, addressing the growing need for sustainable, high-performance materials. Traditional plywood production relies on adhesives enhanced with various fillers to improve physical, mechanical, and operational characteristics. This research explores using native, chemically modified, and activated carbon derived from hazelnut shells as fillers in urea-formaldehyde (UF) resin. The mechanical properties, water absorption, and formaldehyde emissions of the produced plywood were thoroughly analyzed. Key findings demonstrate that incorporating 10 part by weight (pbw) native hazelnut shell flour significantly enhances the modulus of rupture (MOR) and modulus of elasticity (MOE). Chemically modified hazelnut shell flour achieves optimal results at 5 pbw, while activated carbon from hazelnut shells, even at 1 pbw, markedly improves bonding strength and thermal properties. Notably, activated carbon effectively reduces formaldehyde emissions and improves water resistance, indicating better further dimensional stability and lower environmental impact. The study also shows that excessive filler content negatively affects strength parameters, confirming the importance of optimizing filler concentration. These results highlight the potential of hazelnut shells as an eco-friendly alternative filler in plywood production, contributing to waste valorization and environmental sustainability. This study supports the practical application of hazelnut shell fillers, promoting a circular economy and reducing reliance on traditional, less sustainable materials, thus providing a valuable solution for the wood composite industry.

<p align="justify">The development of e-assessment systems that can meet acceptable standards in the education industry is a present focus of researchers in the distance learning area. Cheating and impersonation in online examinations are two common challenges that have spawned diverse solutions that are usually based on continuous authentication and monitoring principles and technologies. Most of the solutions are focused on centralized e-proctoring schemes that depend massively on state-of the-art internet connectivity. However, many users of these systems, especially in the developing countries, have limited internet services. This is a major barrier to effective remote e-assessment of learners as many of these solutions fail with failing internet services. To resolve this challenge, this paper describes a Secure Offline Continuous Authentication and Monitoring(SOCAM) model for remote e-assessment. <strong><em></em></strong></p>

Published: August 2024

Abstract

In this study, we investigate the stability and solid fraction of columns comprised of highly non-convex particles. These particles are constructed by extruding arms onto the faces of Platonic solids, a configuration we term Platonic polypods. We explore the emergence and disappearance of solid-like behavior in the absence of adhesive forces between the particles, referred to as geometric cohesion. This investigation is conducted by varying the number of arms of the particles and the thickness of these arms. To accomplish this, columns are assembled by depositing particles within a cylindrical container, followed by the removal of the container to evaluate the stability of the resulting structures. Experiments were carried out using three distinct materials to assess the influence of the friction coefficient between the grains. Our findings reveal that certain granular systems exhibit geometric cohesion, depending on their geometrical and contact properties. Furthermore, we analyze the initial solid fraction of the columns, demonstrating that these arrangements can achieve stability even at highly loose states, which contrasts with traditional granular materials.

Abstract

We show the dynamic relation between environmental degradation, energy composition, and economic growth in India, utilizing annual data from 1985 to 2022. Our research illuminates a robust, long-term equilibrium relationship among these pivotal variables. Notably, our findings underscore the pivotal role of renewable energy adoption and strategic enhancements in energy efficiency as potent strategies for curtailing CO2 emissions. In addition, we emphasize the imperative of diversifying the energy portfolio and reducing dependence on fossil fuels. Moreover, our Granger causality analysis unveils dynamic interdependencies among these variables, enriching our comprehension of their temporal dynamics. Building upon these compelling results, we proffer a comprehensive set of evidence-based policy recommendations, encompassing the incentivization of renewable energy sources, the augmentation of energy efficiency measures, the introduction of carbon pricing mechanisms, and the steadfast pursuit of sustainable development objectives. This synthesis of findings, intricately coupled with the robust VECM methodology, equips policymakers with invaluable insights to navigate the multifaceted landscape of sustainable development in the dynamic Indian context.

Abstract

In this study, hyperkeratosis score, teat end shape score, teat shape score, teat length score, teat skin score, teat cleanliness score, teat warts score (fibropapillomas), front teat placement score, rear teat placement score and California Mastitis Score (CMT) of 158 milking Holstein cows determined in a dairy farm which is member of Sakarya Dairy Cattle Breeders Association in Sakarya. The relationship between teat traits and Somatic Cell Counts determined. Animals monitored during 12 months and scored at the end of each month. Data’s were evaluated in four season (fall, winter, spring and summer) in the study. Scorings were performed separately for each teat (front right teat, front left teat, rear right teat and rear left teat) in each group. According to the teat, the groups end the ratings. There was a substantial relationship between teat end score groups and CMT for ART (p < 0.01), ALT (p < 0.01), PRT (p < 0.01) and PLT (p < 0.01). There was a strong correlation between teat form classes and CMT for ART (p < 0.05). No statistical association was observed between the teat shape groups and the CMT for ALT, PRT and PLT (p > 0.05). There was a strong correlation between the teat tip score categories and the CMT for ART (p < 0.01), ALT (p < 0.01), PRT (p < 0.01) and PLT (p < 0.01). Based on the teat tip score for ART, 214 teats were smooth, the teats were round, and 182 teats were pointed., there was a significant association between the teat length and the CMT for ART (p < 0.05), ALT (p < 0.05) and PLT (p < 0.01). It was significantly relationship between teat morphological traits and CMT level, therefore it was concluded that the characters such as hyperkeratosis, teat end shape, teat length can be used as selection criteria in animal breeding.

Abstract

This study aimed to evaluate the effects of dietary supplementation with zinc amino acid complex (ZnAA) in reduced crude protein extruded diets for Nile tilapia juveniles. Fish (41.55 g) were fed on a regime of apparent satiety in a randomized design (seven treatments and three repetitions) in 250 L tanks for nine weeks. There were two control diets (no ZnAA), which were categorized as positive control (crude protein content of 318.90 g kg− 1, estimated 264.52 g kg− 1 of digestible protein) and negative control (low crude protein content of 248.32 g kg− 1, estimated 200.90 g kg− 1 of digestible protein). Another five experimental diets with mean reduced low crude protein content (243.08 g kg− 1, estimated 196.17 g kg− 1 of digestible protein) with 20, 40, 60, 80, and 100 mg ZnAA kg− 1 were also tested. Carcass composition, nutrient retention, and zootechnical, hematological, and biochemical responses were evaluated. The negative control, 40, 80, and 100 mg ZnAA kg diet− 1 treatments showed similar growth performance to the positive control. Carcass lipid values and nitrogen retention were lower in the positive control. An increase in dietary ZnAA augmented phosphorus concentration and retention and Zn concentration. The Zn retention was higher in the negative control. Plasma glucose levels and plasma and liver aspartate aminotransferase activity were higher in the positive control. Plasma high-density lipoprotein cholesterol levels were lower in the negative control. Total leukocytes were increased in 80 and 100 mg ZnAA kg diet− 1 treatments. In conclusion, it is recommended to reduce the crude protein content in Nile tilapia extruded diets from 295 to 264 g kg− 1, incorporating 80 mg ZnAA kg diet− 1, since it can contribute to carcass composition and hematobiochemical parameters without harming the fish growth.
Impact of early versus late Artificial Rupture of Membranes during oxytocin induction of labour on the incidence of chorioamnionitis: A randomised controlled trial (ARM Trial)
Authors: G Hill Meghan , Sadler Lynn , Pauleau Emmanuelle , Treadwell Beatrice , Wise Michelle R 
Published: August 2024

Abstract

Background
The approach to induction of labour differs internationally, with timing of amniotomy being controversial. Some institutions favor performing artificial rupture of membranes prior to commencement of oxytocin infusion, with the belief that the labour will progress more efficiently. In other institutions, the approach recommended is for oxytocin infusion with intact amniotic membranes until the person has reached the active phase of labour, citing risk of infection with early amniotomy. Current evidence is inconclusive. We are performing a randomised controlled trial assessing whether delaying amniotomy until the active phase of labour can decrease the rate of chorioamnionitis.
Methods
This is a randomised controlled trial at a single centre in New Zealand. Pregnant people undergoing induction of labour at ≥ 37 weeks gestational age with intact membranes and a singleton gestation are eligible for the trial. Participants are randomised to ‘Early’ amniotomy, at the commencement of oxytocin infusion, or to ‘Late’ amniotomy, when they have reached a cervical dilation of 6 or more centimetres or when they have been receiving oxytocin infusion for 12 hours. The primary outcome of the trial is chorioamnionitis. To detect a decrease in chorioamnionitis from 9–3% with a power of 80% and a 95% CI, we will require 488 participants in total, randomised in a 1:1 ratio.
Discussion
If delaying amniotomy reduces the rate of chorioamnionitis, this is important to inform future practice. Chorioamnionitis entails risk to both the pregnant person and the fetus and is an important contributor to neonatal sepsis, neonatal intensive care unit admission, maternal sepsis, caesarean, wound infection and postoperative infective complications. Conversely, if the rate of chorioamnionitis is not affected by timing of amniotomy this will allow for safe individualization of care.
Trial Registration:
The trial is registered on the Australian and New Zealand Clinical Trials Registry, anzctr.org.au. Full registry title is “Impact of early versus late artificial rupture of membranes during oxytocin induction of labour on the incidence of chorioamnionitis: A randomised controlled trial”.

Published: August 2024

Abstract

Protein pre-training has emerged as a transformative approach for solving diverse biological tasks. While many contemporary methods focus on sequence-based language models, recent findings highlight that protein sequences alone are insufficient to capture the extensive information inherent in protein structures. Recognizing the crucial role of protein structure in defining function and interactions, we introduce Sable, a versatile pre-training model designed to comprehensively understand protein structures. Sable incorporates a novel structural encoding mechanism that enhances inter-atomic information exchange and spatial awareness, combined with robust pre-training strategies and lightweight decoders optimized for specific downstream tasks. This approach enables Sable to consistently outperform existing methods in tasks such as regression, classification, and generation, demonstrating its superior capability in protein structure representation. The code and models will be released in the GitHub repository.
