Increased nutrient inputs to temperate coastal waters have led to increased occurrences of macroalgal blooms worldwide. To identify nutrients that are limiting to macroalgae and to determine whether different forms of these nutrients and long-term ambient nutrient conditions affect macroalgal response, we used in situ enrichment methods and tested the response of 2 bloom-forming species of macr...

A split plot 3 by 3 experiment was designed to investigate and distinguish the relationships among production of primary metabolites (soluble sugar and starch), secondary metabolites (total phenolics, TP; total flavonoids, TF) and leaf gas exchange of three varieties of the Malaysian medicinal herb Labisia pumila Blume, namely the varieties alata, pumila and lanceolata, under three levels of CO...

We determined whether ring-2 carbon of histidine is folate-dependently transferred to carbons 8 (C8) and/or 2 (C2) in urinary uric acid in humans. Two adults collected each urine void for four days. Aliquots of urine for the first day were used for baseline values; then the subjects ingested 0.7 g (3.3 mmol) of l-[ring-2-13C]histidine and collected urine for three experimental days. Aliquots we...

This study aims to develop an enrichment book for Riparian plant species diversity in Kampar Regency. research was carried out with ADDIE development model consisting of the Analysis, Design, Development, Implementation and Evaluation stages. limited Development stage, namely Validity Test due time constraints. The type data used is quantitative qualitative data, sources are primary secondary d...

in the present study the adiabatic temperature of gaseous fuels were calculated and the influence of effective parameters of flame temperature was discussed. firstly, a new computational program named ftc (flame temperature calculations) was prepared to calculate the adiabatic flame temperature and then the effect of initial temperatures of combustion air and fuel, excess air content and oxygen...

the alborz coal basin is located in northern part of iran. the coal deposits of shahrood in eastern alborz, zirab in central alborz and abyek in western alborz were studied as typical coalfields of the basin. shemshak formation which is the main coal-bearing sequence was formed during the triassic-jurassic in the basin. it consists of sandstone, siltstone, shale and claystone, which variedly al...

Deforestation leads to the deterioration of soil fertility which occurs rapidly under tropical climates. Forest rehabilitation is one of the approaches to restore soil fertility and increase the productivity of degraded areas. The objective of this study was to evaluate and compare soil biological properties under enrichment planting and secondary forests at Tapah Hill Forest Reserve, Perak aft...
