Farm Investments of Life Insurance Companies
No full textExcerpts: Life insurance companies have long been an important source of farm-real-estate mortgage funds. These companies currently hold a record proportion – about 25 percent – of the total farm-real-estate mortgage debt. This report deals primarily with farm-real-estate mortgage experience and related items for life insurance companies since the beginning of 1945, with some comparisons to estimated totals for all farm real estate lenders. State and regional data and comparisons are generally confined to the years 1952 and 1953. Data pertaining to such items as principal repayments, refunded mortgages, new loans made, foreclosures, and delinquencies, although based on samples of companies that hold a major part of the total farm-real-estate debt of all life insurance companies, may be insufficient to represent all companies. But data compiled from these samples should serve adequately as general indicators of changes in importance of the various items

No full textEvaluation of the physiological effect of Saccharomyces boulardii a candidate for the manufacture of probiotics isolated from Garcina mangostana fruit pericarps
No full textThis study aimed to isolate the Saccharomyces boulardii strain from Garcinia mangostana fruit from Kinshasa; to determine its thermoresistance; and finally, to determine its antagonistic effect towards Lactobacillus vaginalis and Staphylococcus aureus to determine its suitability for use as a probiotic. The results of this study show that Sacharomyces boulardii isolated from Garcinia mangostana fruit from Kinshasa is tolerant at 44°C and resistant only at 60 and 75°C. Sacharomyces boulardii isolated from Garcinia mangostana fruit in Kinshasa has no antagonistic effect on Lactobaccilus vaginalis and Staphylococcus aureus, so it lives in perfect synergy. Saccharomyces boulardii isolated from the fruit of Garcinia mangostana in Kinshasa could be a good candidate that may well contribute to the restoration of vaginal microbiota than other marketed strains. We therefore suggest that further studies on other probiotic selection criteria be carried out on the isolated strain, with a view to the scientific validation of our results
Land and Income Mobility in Two North Indian Villages: A Note
No full textThis paper examines household-level mobility in land ownership and incomes over a 17-year period (2006–2023) in two villages of Uttar Pradesh—Mahatwar in Ballia district and Harevli in Bijnor district—based on panel data from the Foundation for Agrarian Studies’ Project on Agrarian Relations in India. Results show that mobility in land ownership was low in both villages, reflecting persistent agrarian inequality: about three-fourths of households remained in the same landholding class. However, some landless Scheduled Caste households acquired small plots through non-agricultural earnings and remittances, while a few large landowners experienced downward mobility due to division or sale of land. Income mobility, by contrast, was higher, driven by diversification into non-farm employment and migration. The findings reveal a widening disconnect between land-based and income-based mobility, highlighting that while income growth has improved living standards, land concentration and caste-linked disadvantage remain enduring features of rural Uttar Pradesh
European Trading Arrangements in Fruits and Vegetables
No full textThe European Union (EU) participates in regional and preferential trading arrangements more than any other country or region. Over 70 percent of EU fruit and vegetable imports are from countries benefiting from preferential treatment for some portion of that trade. The most valuable preferences are accorded the 42 least developed countries, while 77 former colonies of EU countries also receive important preferences. The EU’s many preferential agreements create a mosaic of tariffs, quotas, and other import restrictions that vary considerably among products and among preferred partners which makes analysis impossibly complex. These agreements are an integral part of the management of EU imports by the Common Agricultural Policy. Exports from countries without preferences, including the United States, are at a disadvantage in EU market
Research and Analysis on Anti-corrosion of Mountain Photovoltaic Brackets
No full textWith the increasing global demand for renewable energy, solar photovoltaic power generation technology has been widely applied in China and even globally. Especially in mountainous areas, complex terrain resources are cleverly utilized in the construction of photovoltaic power stations, but this also brings severe challenges to the anti-corrosion of photovoltaic brackets. This paper focuses on the anti-corrosion technology of mountain photovoltaic brackets, and deeply explores the influence of natural factors such as mountain climate, sandstorms, and precipitation on the corrosion of photovoltaic brackets. The research results show that the key to improving anti-corrosion performance lies in the selection of bracket materials and optimization of coating processes. After comparing various anti-corrosion treatment methods such as hot-dip galvanizing, spray aluminum coating, and new anti-corrosion materials, it is found that nano coating technology exhibits excellent protective effects in corrosive environments. This study is of great significance for promoting the sustainable development of photovoltaic power generation, providing solid theoretical support and practical guidance for the anti-corrosion design of mountain photovoltaic power stations
