Carbon materials such as graphite and graphene exhibit high electrical conductivity. We examined the electrical conductivity of synthetic and natural graphene powders after the chemical reduction of synthetic and natural graphite oxide from synthetic and natural graphite. The trend of electrical conductivity of both graphene (synthetic and natural) was compared with different graphite materials...

Screening tests for mastitis can play an important role in proactive mastitis control programs. The primary objective of this study was to compare the sensitivity and specificity of milk electrical conductivity (EC) to the California mastitis test (CMT) in commercial dairy cattle in South Africa using Bayesian methods without a perfect reference test. A total of 1848 quarter milk specimens were...

The aim of this study was to investigate the effect herd management practices on milk quality according somatic cell count, standard plate count and electrical conductivity. experimental work carried out at El-Bayoumi dairy farms in Gamasa, Dakahlia Governorate 2016. Managing cows parity, cleanliness score, stocking rate, feeding regime, stage lactation, daily level milking shift had a higher s...

aims: intensification of current environmental legislation leads to an increase wastewater treatment sludge volume. so reducing the sludge volume is considered as a strategy to improve and solve the problems of secondary pollution of sludge. dissolved air flotation (daf) as a substitute clarifier is used for separation of activated sludge liquid-solid phases. the aim of this study was to estima...

Electrical conductivity is an important indicator for water quality assessment. Since the composition of mineral salts affects the electrical conductivity of groundwater, it is important to understand the relationships between mineral salt composition and electrical conductivity. In this present paper, we develop an adaptive neuro-fuzzy inference system (ANFIS) model for groundwater electrical ...

Acid rain still poses a global problem today, exerting many adverse effects on man, animal, and materials. As its research question, the present study tries to find out whether or not acid rains exist in Akure, Nigeria. For so doing, it determines physico-chemical properties of rain water samples, namely pH, temp, Electrical Conductivity (EC), TDS, acidity, SO4-, NO2-, Cl-, and Free CO2. Accord...

The physicochemical qualities of a typical rural-based river were assessed over a 12-month period from August 2010 to July 2011 spanning the spring, summer, autumn and winter seasons. Water samples were collected from six sampling sites along Tyume River and analysed for total nitrogen, orthophosphate, biochemical oxygen demand (BOD), temperature, pH, dissolved oxygen (DO), electrical conductiv...

Different methods to estimate electrical conductivity (EC) of saturated soil paste extract (ECe) 1:2 and 1:5 soil: water suspensions were evaluated. Soil samples taken from different depths (viz. 0-15, 15-30, 30-45, 45-60, 60-90 cm) the wheat field under irrigated saline regimes ranging 1.5 12 dSm-1. The relationship between soil-water suspension extracts (i.e., EC1:2 EC1:5) was established bes...
