Optimizing power grids: A valley-filling heuristic for energy-efficient electric vehicle charging.

The expansion of electric vehicles (EVs) challenges electricity grids by increasing charging demand, thereby making Demand-Side Management (DSM) strategies essential to maintaining balance between supply and demand. Among these strategies, the Valley-Filling approach has emerged as a promising method to optimize renewable energy utilization and alleviate grid stress. This study introduces a novel heuristic, Load Conservation Valley-Filling (LCVF), which builds on the Classical and Optimistic Valley-Filling approaches by incorporating dynamic load conservation principles, enabling better alignment of EV charging with grid capacity.

Maternal Low-Protein Diet During Nursing Leads to Glucose-Insulin Dyshomeostasis and Pancreatic-Islet Dysfunction by Disrupting Glucocorticoid Responsiveness in Male Rats.

Both perinatal malnutrition and elevated glucocorticoids are pivotal triggers of the growing global pandemic of metabolic diseases. Here, we studied the effects of metabolic stress responsiveness on glucose-insulin homeostasis and pancreatic-islet function in male Wistar offspring whose mothers underwent protein restriction during lactation. During the first two weeks after delivery, lactating dams were fed a low-protein (4% protein, LP group) or normal-protein diet (22.

Umbilical vein remodeling is associated with pregestational maternal overweight.

Introduction: Excess weight during pregnancy is a condition that can affect both mother and fetus, through the maternal-fetal interface, which is constituted by the placenta and umbilical cord. The umbilical vein is responsible for transporting oxygen and nutrients to the fetus, and its proper functioning depends on the integrity of its structure. The remodeling of the umbilical vein represents one of the causes of inadequate transport of nutrients to the fetus, being potentially harmful.

Fezolinetant and Elinzanetant Therapy for Menopausal Women Experiencing Vasomotor Symptoms: A Systematic Review and Meta-analysis.

Objective: To assess the efficacy and safety of fezolinetant and elinzanetant for vasomotor symptoms in menopausal women.

Data Sources: MEDLINE, EMBASE, and Cochrane databases were systematically searched until August 22, 2024. Because the Cochrane Library included all the identified randomized controlled trials (RCTs), it was unnecessary to search ClinicalTrials.

Mitigating salinity stress on tomato growth, water regime, gas exchange, and yield with the application of QuitoMax.

This study assessed the intensity of salt stress in the two tomato varieties by measuring variables associated with the water regime, chlorophyll content, normalized difference vegetation index, gas exchange, and yield. The cultivars Amalia and Claudia, which represent tolerance and susceptibility to salinity, were evaluated. Three treatments were established in plastic pots, using a completely randomized design: T1, saline soil (ECse = 6.

The endocannabinoid system's genetic polymorphisms in sickle cell anemia patients.

Sickle cell anemia (SCA) is a monogenic blood disease with complex and multifactorial pathophysiology. The endocannabinoid system (ECS) could be a candidate for modulating SCA complications, such as priapism, as it has demonstrated an essential role in hematopoiesis, platelet aggregation, and immune responses. We evaluated the association of ECS-related single nucleotide polymorphisms (SNP) (FAAH rs324420, MAGL rs604300, CNR1 rs7766029, and CNR2 rs35761398) with priapism in a Brazilian SCA cohort.

Measuring social vulnerability in communities and its association with leprosy burden through spatial intelligence in central West Brazil to guide strategic actions.

Background: It is known that leprosy is a socially determined disease, but most studies using spatial analysis have not considered the vulnerabilities present in these territories.

Objectives: To measure the association between social vulnerability and the burden of leprosy in the urban space of Cuiabá.

Methods: Ecological study, carried out in Cuiabá, Brazil.

Real-world outcomes and predictors of failure of gonioscopy-assisted transluminal trabeculotomy in a large glaucoma cohort: a multicenter study.

This retrospective, comparative, multicenter study aimed to evaluate the real-world outcomes and predictors of failure of Gonioscopy-assisted transluminal trabeculotomy (GATT) at 12 months in glaucoma patients. Predictors of failure of absolute success in bilateral cases (422 eyes of 308 patients) included pre-operative intraocular pressure (IOP; IRR = 1.02; p = 0.

Effective Nitrate Electroconversion to Ammonia Using an Entangled CoO/Graphene Nanoribbon Catalyst.

There has been huge interest among chemical scientists in the electrochemical reduction of nitrate (NO) to ammonia (NH) due to the useful application of NH in nitrogen fertilizers and fuel. To conduct such a complex reduction reaction, which involves eight electrons and eight protons, one needs to develop high-performance (and stable) electrocatalysts that favor the formation of reaction intermediates that are selective toward ammonia production. In the present study, we developed and applied CoO/graphene nanoribbon (GNR) electrocatalysts with excellent properties for the effective reduction of NO to NH, where NH yield rate of 42.

Satisfaction and Workload as Predictors of Psychological Distress in Professionals of Psychosocial Care Centers During the COVID-19 Pandemic.

Background And Aims: The COVID-19 pandemic significantly impacted the mental health of healthcare professionals, especially those working in Psychosocial Care Centers (CAPS), which are crucial services in the Brazilian mental health system. This study aimed to investigate the association between job satisfaction, workload, and psychological distress among CAPS professionals during the pandemic.

Methods: A cross-sectional study was conducted with 53 professionals from seven CAPS.

Water pollution caused by ash from grassland fires alters the molecular, biochemical, and morphological biomarkers of non-biting midge larvae.

The frequency and intensity of wildfires have been increasing in many parts of the world, which may result in biodiversity loss. Wildfires can devastate plant communities, generating toxic ash that pollutes watercourses through runoff. However, our understanding of the effects of ash exposure on aquatic biodiversity is still limited.

The effect of telehealth on clinical outcomes in patients with hypertension and diabetes: A meta-analysis of 106,261 patients.

Introduction: Telemedicine, propelled by recent technological advancements, has transformed healthcare delivery, notably benefiting patients with chronic non-communicable diseases (NCDs) such as systemic arterial hypertension and diabetes mellitus. This meta-analysis of randomized clinical trials aimed to assess the efficacy of telehealth-based interventions on disease control rates and clinical parameters among NCD patients, including systolic and diastolic blood pressure (SBP and DBP), fasting blood glucose (FBG), and glycated hemoglobin (HbA1c) levels.

Methods: We conducted searches in PubMed, Scopus, Web of Science, and the Cochrane Database for interventional studies that compared tele-monitoring with usual care in patients with hypertension and type 2 diabetes mellitus.

Electrical signals dataset from fixed-speed and variable-speed synchronous generators under healthy and faulty conditions.

Proper monitoring of rotating machines is responsible for the efficiency in detecting, diagnosing, or even prognosing failures. Effective monitoring can lead to increased economic viability of any equipment, as it may reduce costly repairs, decrease downtime, and increase safety. Knowing the behaviour of a machine promotes better monitoring of its operation and maintenance.

Toward Sustainable Polyurethane Foams: Effects of Corn Cob Fibers and Silver Nanoparticles on Mechanical Properties and Antimicrobial Activity.

Polyurethane foams (PFs) are widely used in mattresses, upholstery, and insulation, but disposal is difficult due to the disintegration time and environmental hazards of synthetic polyol. This work investigates a sustainable alternative by replacing poly(ethylene glycol) (PEG) with corn cob fibers and incorporating antibacterial silver nanoparticles (AgNPs). Corn cob fibers and sodium hydroxide-treated fibers were used to make foams, with corn cob fibers substituting PEG at 5-30 wt %.
