Agriculture has played 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 system 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 systems 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 systems by farmers was identified using factor analysis. SPSS software was used to analyse 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 system has low initial costs, flexible credit policies motivate adoption, solar water-pumping systems can save electricity, and maintenance and repair costs are affordable. Government policy that includes solar water-pumping systems is motivated by awareness, subsidies for adoption and a fair price to sell energy surpluses. Farmers are recommended to adopt a solar water-pumping system in conjunction with a drip irrigation system 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 system in Gujarat, India are identified based on interviews with one hundred and fifty randomly sel

Decomposition solutions and B?cklund transformations of the B-type and C-type Kadomtsev–Petviashvili equations

引用

Communications in Theoretical Physics 2024年第6期 36-46页

作者： Xiazhi Hao S y Lou College of Science Zhejiang University of Technology School of Physical Science and Technology Ningbo University

This paper introduces a modified formal variable separation approach, showcasing a systematic and notably straightforward methodology for analyzing the B-type Kadomtsev–Petviashvili(BKP) equation. Through the application of this approach, we successfully ascertain decomposition solutions, B?cklund transformations, the Lax pair, and the linear superposition solution associated with the aforementioned equation. Furthermore, we expand the utilization of this technique to the C-type Kadomtsev–Petviashvili(CKP) equation, leading to the derivation of decomposition solutions, B?cklund transformations, and the Lax pair specific to this *** results obtained not only underscore the efficacy of the proposed approach, but also highlight its potential in offering a profound comprehension of integrable behaviors in nonlinear systems. Moreover, this approach demonstrates an efficient framework for establishing interrelations between diverse systems.

HI in High Gas-phase Metallicity Dwarf Galaxy WISEA J230615.06+143927.9

Research in Astronomy and Astrophysics 2024年第1期24卷 292-299页

We present resolved Giant Metrewave Radio Telescope H I observations of the high gas-phase metallicity dwarf galaxy WISEA J230615.06+143927.9(z = 0.005)(hereafter J2306) and investigate whether it could be a Tidal Dwarf Galaxy(TDG) candidate. TDGs are observed to have higher metallicities than normal dwarfs. J2306 has an unusual combination of a blue g-r color of 0.23 mag, irregular optical morphology and high-metallicity(12 +log(O/H) = 8.68 ± 0.14), making it an interesting galaxy to study in more detail. We find J2306 to be an H I rich galaxy with a large extended, unperturbed rotating H I disk. Using our H I data we estimated its dynamical mass and found the galaxy to be dark matter(DM) dominated within its H I radius. The quantity of DM, inferred from its dynamical mass, appears to rule out J2306 as an evolved TDG. A wide area environment search reveals J2306 to be isolated from any larger galaxies which could have been the source of its high gas metallicity. Additionally, the H I morphology and kinematics of the galaxy show no indication of a recent merger to explain the *** detailed optical spectroscopic observations of J2306 might provide an answer to how a seemingly ordinary irregular dwarf galaxy achieved such a high level of metal enrichment.

Rivaroxaban’s vascular dose for the neurovascular clinician

引用

中华神经外科杂志(英文) 2024年第3期10卷 1-3页

作者： Chong Ji y. Jan Kalimullah Stroke Center New York Medical College Westchester Medical Center Valhalla NY USA Neurovascular Fellow New York Medical College Westchester Medical Center Valhalla NY USA

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 syndrome. 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.
