Phytochemical screening and antihelminthic activity of leaf and root extracts of Cassia tora plant

Cassia tora is one of the most important sources of medicinally important phytochemicals and widely used in Ayurvedic and Chinese system of medicine. The fresh plants of cassia tora were collected from the different locality of Dharan, Sunsari district during the month of August. In this study leaves and root extracts were subjected to extraction by soxheletion by using ethanol and water and the extracts were subjected to antibacterial activity against Staphylococcus aureus. and Citrobacter koseri, the ethanolic extracts were screened for antihelmenthic activity against Indian adult earth worm (Pheretima posthuma) with a moderate result. The result of antibacterial activity revealed that aqueous extract  of leaves and roots showed better activity in comparison to aqueous extracts particularly against gram positive bacteria (Staphylococcus aureus)

Evaluation of phytochemical parameters, antibacterial and antihelminthic activity of leaves and bark extracts of plant Bombax ceiba

Bombax ceiba, commonly known as the red silk-cotton tree, is a large, briefly deciduous tree occurring in warm monsoon forests in southern Asia. Various phytochemical constituents present in different plant parts has been already reported earlier to possess many biological activities, here in this work extraction was performed by mixture of solvent (distilled water: ethanol) as well as the individual solvents (water) and (ethanol). The phytochemical screening of the leaves and barks was found to exhibit the presence of carbohydrates, glycoside, saponin, phytosterol phenol, tannins, flavonoid, proteins and diterpenes and negative result for alkaloids in all the solvent extracts. The ethanolic extract of leaves was subjected to antihelmenthic activity and the result was found to be moderat

An Inventory and Assessment of Sample Sources for Survey Research with Agricultural Producers in the U.S.

Researchers need probability samples to collect representative survey data about the behaviors and attitudes of agricultural producers they study in relation to the natural resources that they manage, yet obtaining accurate and complete sampling frames is challenging. We extract data from a publication database to identify the most commonly used sampling frame sources in survey research of agricultural producers in the U.S., finding that government program participant lists are used most often, while private vendor samples are increasingly being purchased. Based on our research experience, we find that for many projects, private vendors can provide the most rigorous samples. Given that survey methods remain a useful and popular method for studying the behaviors and attitudes of producers on a variety of topics, such an assessment and guide is needed for researchers and practitioners

A Social Science Assessment of Conservation Practices in the Red River Basin of Minnesota

This report describes a social science assessment of conservation practices conducted in the Red River Basin, Minnesota. The study was conducted by the Department of Forest Resources, University of Minnesota in collaboration with the Northwest Regional Sustainable Development Partnership, University of Minnesota. The overarching goal of the study was to provide a science-based approach to understanding and promoting conservation practices in the Red River Basin. The specific study objectives were to (1) identify determinants of conservation practice adoption among agricultural producers in the Red River Basin, (2) better understand how conservation practices and determinants of adoption vary across subwatershed populations within the Red River basin (e.g., geographically, demographically, socially), and (3) to offer strategies for policy-makers, resource professionals and other local actors to best design and promote water resource programs that are ecologically, hydrologically, and socially relevant and responsive to changing conditions.University of Minnesota Northwest Regional Sustainable Development partnership Minnesota Department of Natural Resource

Groundwater Management: Capacity Assessment at the Local Level, A survey of Minnesota Association of Soil and Water Conservation Districts

This report describes a capacity assessment of Minnesota Soil and Water Conservation District (SWCD) staff to engage in groundwater protection. The study was conducted by the Department of Forest Resources, University of Minnesota in partnership with the Minnesota Department of Natural Resources (MNDNR) and Minnesota Association of Soil and Water Conservation Districts (MASWCD). The overarching goal of the study was to examine local capacity and capacity building programs for groundwater management.University of Minnesota Regional Sustainable Development Partnership Department of Forest Resources College of Food, Agriculture and Natural Resource Science University of Minnesot

Seismic microzonation and soil-structure resonance analysis in Suryabinayak Municipality, Bhaktapur, Nepal: insights from ambient vibration measurements

AbstractBhaktapur, lying in the Kathmandu Basin, suffered damages during the 2015 Gorkha Earthquake, potentially exacerbated by local site effects. This research addresses the lack of site response study on Suryabinayak Municipality, located in the southern part of Bhaktapur district. Horizontal to Vertical Spectral Ratio (HVSR) and Floor Spectral Ratio (FSR) methods were employed to determine the fundamental frequencies of soil deposits at 241 free field stations and 20 Reinforced Concrete (RC) isolated buildings respectively. The fundamental frequency of soil deposits varies from 0.27 Hz to 10.00 Hz. Higher frequencies were noted near the basin edges, attributed to shallow sediment deposits, whereas a lower frequencies prevailed towards the basin centre due to an increase in sediment thickness. Out of 20 buildings studied, 7 are highly susceptible to soil-structure resonance as the frequency disparity between building and free-field is less than 15%. This research not only quantified the frequency distribution and soil-structure resonance likelihood but also established a correlation between building height and its fundamental frequency. A significant correlation is observed with a coefficient of determination (R2) value of 60.64% and 83.36% in the longitudinal and transverse directions respectively. The study’s results can be endorsed to mitigate seismic hazards, build seismic-resilient structures, and maintain historical monuments

The Future of Agriculture in a Water-Rich State

In 1920, Minnesota held 2.4 million people and 132,744 farms. Corn production was near 100 million bushels per year. By 1929, 18.5 million acres were under cultivation. Nearly 100 years later, the state has 5.4 million people, 74,500 farms, and 26 million acres of farmland. Annual production of corn is about 1.5 billion bushels and soybean is about 380 million bushels. Over that century, agricultural technology and infrastructure changed profoundly..
