Abstract The coupled MODFLOW-HYDRUS software package was used to produce a saturated-unsaturated flow model for a Flood Spreading System (FSS) and its associated aquifer. The study aim to improve simulations of near-surface hydrological processes, including temporal and spatial variation in groundwater recharge rates. The coupled model was built with average RMSE=1.1 and 1.3 for calibration ...

The unsaturated zone and the saturated/unsaturated interface region are important links between groundwater and the land surface. They provide storage capacity for both water and contaminants; a reactor medium for physical, chemical and biological processes; a delay time between the release of a contaminant into the unsaturated zone and its influx into the saturated zone and, a domain for the l...

Palmitic, stearic, oleic, and linoleic acids at concentrations of 200 nmol/ml all inhibited autolysin activity 80% or more in whole cells or cell-free extracts. This concentration of the saturated fatty acids palmitic acid and stearic acid had little or no effect on the growth of whole cells or protoplasts. However, the unsaturated fatty acids oleic acid and linoleic acid induced lysis in both ...

The degree of incorporation of injected l-C-acetate into tissue cholesterol on cholesterol free diets was much higher in the liver and plasma of swine ingesting saturated than unsaturated fat. The levels of cholesterol in all tissues increased with the presence of fat or cholesterol in the diet. In most cases, especially in the presence of cholesterol, cholesterol levels were highest in the pre...

soil hydraulic properties such as saturated and unsaturated hydraulic conductivity play an important role in environmental research. since direct measurement of these soil hydraulic properties is time-consuming and costly, indirect methods such as pedotransfer functions and artificial neural networks (ann) were developed based on readily available parameters. in this study, the use of ann to pr...

Background & Aim:Armenian cucumber (Cucumis melo var. flexuosus) is one of the varieties of Cucurbitaceae family that is freshly consumed in Iran, while due to the presence of useful fatty acids and minerals, it can play a special role in the health diet. The aim of this study was to evaluate the quantitative and qualitative of fatty acids in the seeds of Armenian cucu...

The effects of saturated and unsaturated fatty acids on the growth of Bordetella pertussis strain 114 in defined medium were tested. Individual fatty acids were found to be either inhibitory or stimulatory to growth, depending on concentration. Myristic (C14), pentadecanoic (C15), and palmitic (C16) acids were the most inhibitory saturated fatty acids tested. B. pertussis 114 was extremely sens...

The chemical screening carried out on Schizochytrium sp. biomass led the identification of 24 types of organic compounds belonging to n-alkanes, 1-alkenes, 1-alkanols, free fatty acids, methyl and ethyl esters of saturated and unsaturated fatty acids, saturated tri- and diglycerides, unsaturated monoglycerides, wax esters, sterols, triterpenes, and mono- and sesquiterpenes. Moreover, a sample c...
