The effects of light intensity (µ mol m-2 s-1) and different levels of Nitrogen was made on the biomass and lipid of microalgae Chaetoceros calcitrans under  laboratory conditions in the north of Iran in 2016. The pure strand of C. calcitrans with F/2 media (8 sets of 3 flasks) were placed in front of the light source at values of 80, 160, and 240 µ mol m-2 s-1. The cell count was collected in ...

abstract the association between neotyphodium spp. endophytes and cool-season grasses, particularly tall fescue (festuca arundinacea, schreb), represents a widespread type of mutualism in nature. numerous researches were performed about positive effect of symbiosis on plant resistance to different stresses but the role of symbiosis on nutrients uptake particularly potassium uptake and k-bearing...

This study investigated the nutrient composition of ready cooked foods commonly consumed in southern Thailand. Four samples of fourteen types; eight curry dishes, one sweet and sour curry, a soup dish, one stir-fried curry, one stir-fried dish and two single plate dishes were each purchased from 4 different shops around Hat Yai district. The edible part was blended and analysed for its nutrient...

OBJECTIVE Nutrient Reference Values (NRV) are evidence-based benchmarks for assessing the dietary adequacy of individuals and population groups as well as informing public health nutrition policies and programmes. The present paper presents the findings of an analysis of the views of submitters to a draft document associated with the development of the 2006 NRV for Australia and New Zealand. Th...

Background: Investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. The advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. Th...

BACKGROUND AND OBJECTIVE Despite assumed similarities in Canadian and US dietary habits, some differences in food availability and nutrient fortification exist. Food-frequency questionnaires designed for the USA may therefore not provide the most accurate estimates of dietary intake in Canadian populations. Hence, we undertook to evaluate and modify the National Cancer Institute's Diet History ...

Eutrophication and acidification are among the major stressors on freshwater ecosystems in northern Europe and North America, but possible consequences of interactions between pH and nutrients on ecological status assessment and species richness patterns have not previously been assessed. Using data from 52 river sites throughout Norway, we investigated the combined effects of pH and nutrients ...
