This article presents an experimental study.that clarifies the relationship between the initial fracture stress and fatigue limit of glass fiber reinforced unsaturated poly.ster resin specimens with a laminated structure taken from a pultruded square pipe. Quasi-static bending and tension tests are performed with acoustic emission (AE) measurements to identify.ng the occurrence of initial fracture during testing. AE and observation results have clarified the occurrence of initial fracture was detected by.maximum acoustic energy.values and corresponding fiber breakage in the unidirectional (UD) bundles. Moreover, the ratio of initial fracture stress to ultimate strength is 32% in bending and 26% in tension, when comparing stress and strains on the tension side of the UD lay.r. These values are in good agreement with each other and with the measured tensile fatigue limit when the cy.lic stress is at 25% of the tensile strength. Initial fracture stress obtained by.static tests is close values to the fatigue limit which will greatly.contribute to the prediction of the fatigue limit.

Understanding the in vivo transport process provides guidelines for designing ideal nanoparticles (NPs) with higher efficacy.and fewer off-target effects. Many.factors, such as particle size, morphology. surface potential, structural stability. and etc., may.influence the delivering process of NPs due to the existence of various phy.iological barriers within the body. Herein, we summarise the distinct influences of NP phy.icochemical properties on the four consecutive in vivo transport steps: (1) navigating with bloodstream within blood vessels, (2) transport across vasculature walls into tumour tissues, (3) intratumoural transport through the interstitial space, and (4) cellular uptake & intracellular delivery.by.cancerous cells. We found that the philosophy.behind the current consensus for NP design has certain similarities to the “y.n-y.ng” theory.in traditional Chinese culture. Almost all phy.icochemical properties, regardless of big or small sizes, long or short length, positive or negative zeta potentials, are double-edged swords. The balance of potential benefits and side effects, drug selectivity.and accessibility.should be fully.considered when optimising particle design, similar to the “y.n-y.ng harmony.. This paper presents a comprehensive review of the advancements in NPs research, focusing on their distinct features in tumour targeting, drug delivery. and cell uptake. Additionally. it deliberates on future developmental trends and potential obstacles, thereby.aiming to uncover the way. these characteristics influence the NPs’ biological activity.and provide theoretical guidance for the targeted delivery.of NPs. © 2024, Chinese Medical Multimedia Press Co Ltd.

Agriculture has play.d an important role in the growth of the Indian economy. Water and electricity.are essential inputs for agriculture today. India produces the third-largest amount of electricity.in the world, behind China and the USA. As an incentive to increase production, most states provide free electricity.to farmers. Free electricity.has decreased groundwater levels and increased electricity.consumption. The objective of this study.was to find out the factors that influenced farmers to adopt a solar water-pumping sy.tem in Gujarat. The samples were randomly.selected. This study.examined the entire state of Gujarat. One hundred and fifty.farmers who adopted solar water-pumping sy.tems were interviewed, including 50 banana farmers, 50 cotton farmers and 50 groundnut farmers. Primary.data were collected through an interview. The adoption of solar water-pumping sy.tems by.farmers was identified using factor analy.is. SPSS software was used to analy.e the data collected. In this study. only.two factors contributed to the variance of 59.469%. The adoption of solar water pumps by.farmers was influenced by.government policy.and economic benefits. An economic benefit variance of 33.20% was found, while a government policy.variance was 26.27%. A solar water-pumping sy.tem has low initial costs, flexible credit policies motivate adoption, solar water-pumping sy.tems can save electricity. and maintenance and repair costs are affordable. Government policy.that includes solar water-pumping sy.tems is motivated by.awareness, subsidies for adoption and a fair price to sell energy.surpluses. Farmers are recommended to adopt a solar water-pumping sy.tem in conjunction with a drip irrigation sy.tem to receive additional income. The successful scheme will be recommended to other states in India for implementation. The factors that influence farmers to adopt a solar water-pumping sy.tem in Gujarat, India are identified based on interviews with one hundred and fifty.randomly.sel

Rivaroxaban, a direct oral anticoagulant, has proven efficacy.and safety.at its standard dose in the treatment and prevention of various vascular conditions. These include the treatment of venous thromboembolism and stroke prevention in non-valvular atrial fibrillation. A "very.low" vascular dose of rivaroxaban, when combined with low-dose aspirin, has been demonstrated to reduce major adverse cardiovascular events, including stroke, in both acute and chronic coronary.sy.drome. The combination of rivaroxaban and low-dose aspirin could potentially.offer an additional strategy.for stroke prevention in selected non-atrial fibrillation patients who are at a high risk of stroke.

East Japan Railway.Company.(JR East) is aiming to “realize driverless train operation” as one of the key.measures to respond to rapid changes in the business environment. Currently. Automatic Train Operation (ATO) equipment is not installed on the Shinkansen, but there are plans to introduce ATO or driverless operation in the near future. From 2018–2021, the Ministry.of Land, Infrastructure, Transport and Tourism (MLIT) held the “ATO Technology.Study.Group for Railway.” in which the concept of technical requirements necessary.for driverless operation was discussed. In 2021, JR East conducted the GOA4 demonstration test on the Joetsu Shinkansen. In this test, we were able to confirm the basic functions of Shinkansen vehicles such as automatic departure control, speed control, fixed position stop control, and remote stop control using ATO. We aim to realize unattended operation (GOA4) for deadhead trains between Niigata Station and the Niigata Shinkansen Rolling Stock Center by.the end of the 2020 s, and driverless operation (GOA3) for passenger trains of the Joetsu Shinkansen by.the mid-2030s and continue to develop the necessary.technologies and build sy.tems. © 2024 The Authors
