Various assessment characteristics have been used to evaluate the physiological condition of the skin, including skin moisture, elasticity, oil, and color. This often requires specific pieces of equipment such as a microscope. Although everyday evaluations may be needed to maintain skin condition, a particular piece of equipment may not be suitable for daily use. In this paper, it was proposed ...
the accuracy and effectiveness of precision agriculture is highly depending on accuracy and time analysis of the soil moisture conditions. monitoring of the soil water status is a proper method for optimizing the agricultural irrigation. automation irrigation, based on soil moisture measurement by smart sensors has the potential to provide maximum water use efficiency by maintaining soil moistu...
The key objective of our paper is to monitor the soil’s moisture content during it’s dry and wet conditions with the aid of a moisture sensor circuit, calculate the corresponding Relative Humidity and irrigate it based on its nature , using a PC based LabVIEW system, NI ELVIS and an automatic water inlet setup. The moisture sensor circuit which is built on the NI ELVIS consists of two copper st...
Long term moisture exposure has been shown to affect the mechanical performance of polymeric composite structures. This reduction in mechanical performance must be accommodated for during product design in order to ensure long term structure survival. In order to determine the longterm moisture effects on composite components, representative parts are commonly tested after having been exposed t...
key words: Silk, fibroin, accelerated ageing, condition, yellowness index, molecular weight, sorbed moisture To ensure continued access and long-term preservation it is essential to understand the condition of an artefact, and the behaviour of its component materials, in order to set limits on display and handling. In support of curators and conservators of collections with historic textiles, w...
Urbanization-associated land use and land cover (LULC) changes lead to modifications of surface microclimatic and hydrological conditions, including the formation of urban heat islands and changes in surface runoff pattern. The goal of the paper is to investigate the changes of biophysical variables due to urbanization induced LULC changes in Indianapolis, USA, from 2001 to 2006. The biophysica...
Potassium (K) fertilizer management is beneficial for improving growth, yield and yield components of field crops under moisture stress condition in semiarid climates. Field experiments were conducted to study the response of maize (Zea mays L., cv. Azam) to foliar and soil applied K during summer 2013 and 2014. The experiments were carried out at the Agronomy Research Farm of The University of...
Frequency Domain Spectroscopy (FDS) is an effective tool allowing assessing the condition of oil-paper insulation system in power equipment. However, results from these measurements are known to be greatly influenced by various parameters, including insulation aging, moisture content, and insulation geometry/volume, together with environmental condition such as temperature. In this contribution...
The aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable H+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. Drug resin complexes (DRC) were prepared and evaluated for the percentage of moisture gain when placed in a humidity c...
introductionmany aspect strongly influence regional climate includes localized surface processes, large-scale patterns, especially mid and upper level tropospheric circulation and many factors control precipitation in the west of iran includes location of emigrate westerly winds systems, jet streams location, humidity flux and topography. upper tropospheric jet stream constitutes a significant ...
