OBJECTIVES To survey existing literature comparing nutrient content of organic and conventional crops using statistical methods to identify significant differences and trends in the data. DESIGN Published comparative measurements of organic and conventional nutrient content were entered into a database for calculation. For each organic-to-conventional comparison, a percent difference was calc...

Damage to the genome is recognized as a fundamental cause of developmental and degenerative diseases. Several micronutrients play an important role in protecting against DNA damage events generated through endogenous and exogenous factors by acting as cofactors or substrates for enzymes that detoxify genotoxins as well as enzymes involved in DNA repair, methylation, and synthesis. In addition, ...

The hypothesis that the nature and force of PAH stress responses from plankton systems are coupled to the nutrient status of that system was tested in a mesocosm experiment. Four treatments were applied consisting of control (Cn), pyrene exposed (PYl. nutrient spiked (Nul. and nutrient spiked and pyrene exposed (NuPy) groups in replicate bags (n = 3) representing plankton communities including ...

Rainfall erosion is a major cause of inducing soil degradation, and rainfall patterns have a significant influence on the process of sediment yield and nutrient loss. The mathematical models developed in this study were used to simulate the sediment and nutrient loss in surface runoff. Four rainfall patterns, each with a different rainfall intensity variation, were applied during the simulated ...

Objectives: To survey existing literature comparing nutrient content of organic and conventional crops using statistical methods to identify significant differences and trends in the data. Design: Published comparative measurements of organic and conventional nutrient content were entered into a database for calculation. For each organic-to-conventional comparison, a percent difference was calc...

AIM The aim of our study was to evaluate the inadequacy of voluntary energy and nutrient intake on the first day of hospital admission. PATIENTS AND METHODS A cross-sectional study was carried out in two terciary care hospitals, with a probabilistic sample of 50% of in-patients. Dietary intake was evaluated by a 24-hour dietary recall, and undernutrition was screened through the Nutritional R...

Many environments on Earth experience nutrient limitation and as a result have nongrowing or very slowly growing bacterial populations. To better understand bacterial respiration under environmentally relevant conditions, the effect of nutrient limitation on respiration rates of heterotrophic bacteria was measured. The oxygen consumption and population density of batch cultures of Escherichia c...

In any managed system of animal production the problem is to match the nutrient requirement of the animal with a supply of the nutrient in the feed to achieve the maximum economic return. Any matching system has one major prerequisite : the nutrient requirement and nutrient content of feedstuffs must be expressed in the same units. The manner in which this matching is carried out may differ acc...

in this study, the performance of a fabricated fluffer was evaluated and compared with common field curing methods for alfalfa. the drying rate, baling loss and alfalfa nutrient value (dry matter and crude protein) were the criteria for evaluation. the alfalfa was cut using a mower-conditioner. a randomized complete block experimental design was used with three treatments (fluffing swathed alfa...

training systems and calcium foliar application can improve apple fruits pigmentation by changing mineral compositions. in this study, effect of foliar application of calcium chloride with different concentrations (0, 0.75, 1.5 and 3 g l-1) over 2, 4 and 6 weeks before harvest time on fruit mineral nutrient composition and colour values of apple cvs. gala and delbarestival which trained in thre...
