Abstract A supercapacitor (SC) is a device that possesses outstanding potential to impart significant breakthroughs in energy storage. The current study deals with an experimental investigation in developing NiCo layered double hydroxides/reduced graphene oxide/ Bismuth sulfide ()nanocomposites and exploring its characterization as well as electrochemical measurement. Efficient straightforward and adaptable synthetic approach is implemented to prepare the nanocomposite. In the present investigation XRD, SEM, EDS, TEM, Raman spectroscopy are applied for the characterization while CV, GCD are used for electrochemical measurement of the nanocomposite. In the present study, the as-prepared nanocomposite exhibits rod type structure. The nanocomposite exhibits a decreased band gap and greater free electrons, suggesting that the nanocomposite favors electron transport. The nanocomposite possesses significantly high specific capacitance value of 1139 F/g at current density (CD) of 1 A/g compared to that of NiCo-LDHs/rGOand. Further, the nanocomposite exhibits energy density (ED) of 36.86 Wh/kg and power density (PD) of 919 W/kg at a current density of 1 A/g. Because of its non-toxicity, plentiful availability, environment friendly and cost effectiveness, the as-developed nanocomposite finds significant real-world applications in SCs.

Would it be possible to define a procedure capable to find all the existing cycles within the Collatz sequences? In this article we address this question in two stages: in the first one, we propose an equivalent and reversible set of actions to represent any Hailstone sequence. In the second one, we show a condition which any loop satisfies within this new definition, ultimately revealing that the problem 3n + 1 generates just a single cycle for any value of n, being moreover, always reached.

The present study was undertaken to assess the yield gap through Front Line Demonstrations (FLDs) on tomato crops. Krishi Vigyan Kendra, Malkangiri (Odisha), conducted 13 trials on tomatoes in 2015-16 and 2016-17 across different villages. The predominant grower practices were treated as controls, while recommended practices were implemented in demonstration fields. Over the two years, the average yield in the demonstration fields was 622.3 quintals per hectare (q/ha), compared to 305.2 q/ha in the control fields. The average technology gap, representing the difference between potential and actual yields in the demonstration fields, was found to be 377.7 q/ha. The technology index, indicating the percentage deviation from potential yield achieved averaged 37.77%.

Nursing profession is the perfect blend of sacrifice and satisfaction. The overall career field of nursing provides stability and job security, both highly attractive to nursing graduates. Given the benefits, nursing is a profession that remains highly demanding and stressful. In comparison to the early days of nursing, we see that there exists a very strong competitive mind-set among the nursing students; each in strong pursuit of achieving excellence. In all these situations resilience is the force that helps the students to get back on their feet and press ahead. The study aimed to assess stress resilience among undergraduate nursing students. Cross-sectional descriptive design is used in the study. A sample size of 110 undergraduate nursing students of semester and year-based systems was selected using convenient sampling technique. A structured demographic questionnaire and a standardized 14-item resilience scale was used to measure the level of stress resilience. The data was analysed by using descriptive and inferential statistics. The study revealed that more than half, 63.64% of students have a high resilience tendency with a mean of 73.46 and standard deviation of 10.61. It is observed by the study that there is significant association between the level of stress resilience and the demographic variable; most recent exam result. The study revealed that nursing students have a high resilience tendency, which is significant for the empowerment of each nursing student.

Nuts are nutrient-dense foods rich in unsaturated fatty acids, protein, dietary fiber, vitamins, and minerals. The present prebirth cohort study examined the association between maternal nut intake during pregnancy and the risk of childhood behavioral problems in 5-year-old Japanese children. Study subjects were 1199 mother-child pairs. Dietary intake was assessed using a diet history questionnaire. Emotional problems, conduct problems, hyperactivity problems, peer problems, and low prosocial behavior were assessed using the parent-reported version of the Strengths and Difficulties Questionnaire. Adjustments were made for a priori-selected nondietary confounders and potentially related dietary factors. Compared with mothers who had not eaten nuts during pregnancy, mothers who had eaten nuts had a significantly reduced risk of peer problems in children; the adjusted odds ratio was 0.64 (95% confidence interval: 0.42-0.97). There were no measurable associations between maternal consumption of nuts during pregnancy and the risk of childhood emotional problems, conduct problems, hyperactivity problems, and low prosocial behavior. Maternal consumption of nuts during pregnancy may be associated with a decreased risk of peer problems in 5-year-old children.

Publikace „Řízení rizik procesů a bezpečnost složitých technických děl 2024“ je věnována rizikům a jejich řízení ve prospěch bezpečnosti především v oblasti technologií. Údaje i výsledky uvedené ve sděleních ukazují řadu problémů, které je třeba řešit s cílem zajistit bezpečnost zařízení, celých kompletních technických celků i experimentů. Ukazují, že bezpečnost sledovaných entit, tj. procesů i objektů, je významně ovlivněna nejen vnitřními podmínkami, ale také vnějšími podmínkami a jejich vývojem v čase a s tím spojeným nedostatečným lidským poznáním a schopnostmi.
