Compositional and metabolic quotient analysis of heavy metal contaminated soil after electroremediation

Environmental Earth Sciences, 2015
Heavy metal soil contamination provides a danger both to human and environmental ecosystem health and is still on the rise in many developing countries. Electroremediation provides an innovative method to remedy contamination of soils by heavy metals. Fundamental to the acceptance of any soil remedial technique is proof that positive benefits outweigh ...

Plasma leptin concentrations, basal metabolic rates and respiratory quotients in young and older adults

International Journal of Obesity, 2000
To-examine the interrelationship of circulating leptin concentrations, basal metabolic rates (BMR) and respiratory quotients (RQ) in young and older adults.Cross sectional study.Seventy-six Australian men and women, 48 young (< 35 y) and 28 older ( > or = 50 y).Fasting plasma leptin concentrations by RIA, BMR and RQ by indirect calorimetry, percentage ...

Estimation of a Derivative by a Difference Quotient: Its Application to Hepatocyte Lactate Metabolism

Biometrics, 1985
Values of the derivative of a convex function are estimated from data for the function by assigning the difference quotients of the observations to appropriate values of the determining variable. The procedure is illustrated for the time course of hepatocytes incubated with lactate, of amount l, for which pyruvate, of amount p, is also observed.

Effects of heavy metal stress on the metabolic quotient of the soil microflora

Soil Biology and Biochemistry, 1996
A variety of quantitative measurements such as viable counts, microbial biomass (Cmic), respiration, enzyme activities or ATP contents may be used to study the effects of heavy metals on the soil microflora (Babich and Stotzky, 1985; Brookes et al., 1986).

Metabolic quotients for recombinant CHO and BHK cell lines producing human anttthrombin III

Biotechnology Letters, 1990
Specific consumption and production rates of nutrients and by-products (metabolic quotients) were estimated from batch growth data for recombinant CHO and BHK cell lines. Distinct differences were identified for the two types of continuous cell lines and were further observed for the adherent baby hamster kidney cells as a function of serum ...

Effects of ambient temperature on metabolic rate, respiratory quotient, and torpor in an arctic hibernator

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2000
Arctic ground squirrels ( Spermophilus parryii) overwinter in hibernaculum conditions that are substantially below freezing. During torpor, captive arctic ground squirrels displayed ambient temperature (Ta)-dependent patterns of core body temperature (Tb), metabolic rate (TMR), and metabolic fuel use, as determined by respiratory quotient (RQ).

The effect of environmental temperature on resting metabolic rate and respiratory quotient following elective surgery

Clinical Nutrition, 1983
Twenty male patients undergoing routine elective abdominal surgery of moderate severity nursed at either 20 or 28 degrees C had indirect calorimetry carried out on a control day pre-operatively and for the first four post-operative days. The mean resting metabolic rate over the four post-operative days was significantly elevated by 9% above control ...

Respiratory quotient and embryological development of metabolic heat production in the rhea (Rhea americana)

Journal of Thermal Biology, 1997
Abstract 1. 1. Rheas ( Rhea americana ) show a typical embryonic course of heat production with a plateau phase between days 27 and 39 (total incubation time 38–42 d). 2. 2. In the plateau phase mean oxygen consumption is about 90 ml h −1 (range 87–108) or 0.17 ml (g h) −1 (range 0.164–0.211).

Temporally-variable productivity quotients on a coral atoll: Implications for estimates of reef metabolism

Marine Chemistry, 2019
Abstract Measurements of net ecosystem productivity (NEP) and calcification (NEC) from contemporary coral reefs provide a baseline for monitoring the impacts of future stressors like ocean acidification and sea-surface warming. However, separating secular trends from natural variability requires NEP and NEC records across a wide range of spatial and ...

Microbial respiratory quotient during basal metabolism and after glucose amendment in soils and litter

Soil Biology and Biochemistry, 2001
Abstract The microbial respiratory quotient (RQ), defined as the ratio of mol CO 2 evolution per mol O 2 uptake, was estimated in soils in northern and southern Germany under different land use with and without glucose addition in order to: (i) test the degree of corresponding data of the two procedures, and (ii) evaluate discrepancies with ...
