The effects of nutrient load reductions on the biomass of N-fixing cyanobacteria were evaluated in the scale of the Gulf of Finland. The two analysed reduction scenarios were Finnish national agenda and the improvement of phosphorus removal in the present purification plants of St. Petersburg. The effects of load reduction scenarios were tested by using a 3D-ecosystem model with a horizontal re...
Rice cultivation generates large amount of crop residues of which only 20% are utilized for industrial and domestic purposes. In most developing countries especially southeast Asia, rice straw is used as part of feeding ingredients for the ruminants. However, due to its low protein content and high level of lignin and silica, there is limitation to its digestibility and nutritional value. To ut...
The calyx of Held is a giant glutamatergic synapse in the auditory system and displays multiple forms of short-term facilitation and depression. This study presents a detailed model of short-term plasticity at this synapse. The main components of the model are the presynaptic vesicle dynamics, which include passive and activity-dependent recycling, calcium-dependent exocytosis and the postsynap...
The use of a Lead Slowing-Down Spectrometer (LSDS) is considered as a possible option for nondestructive assay of fissile material in used (spent) nuclear fuel. The primary objective is to quantify the remaining fissile content of the fuel consisting mainly of Pu and U. The characterization of spent fuel is particularly important for nuclear safeguards and for determining the fuel burn-up level...
Spent biomass of different seaweeds such as Sargassum wightii, Turbinaria conoides, Padina tetrastomata and Ulva lactuca were evaluated for the nutritional benefits in aqua feeds. Basic nutritional value, of seaweeds contains a number of pigments, defensive and storage compounds, and secondary metabolites that could have beneficial effects in farmed fish. Only a small fraction of algal species ...
Background and Objectives: During Ramadan, the ninth month in the Islamic calendar, Muslims abstain from eating and drinking from sunrise adhaan to sunset adhaan. This long fasting period can cause change in certain metabolic and hormonal indices and affect eating behaviors and nutrient intake. Therefore, the purpose of this study was to assess nutrient intake in fasting people in Qom, Iran. ...
M icroclimate is the suite of climatic conditions measured in localized areas near the earth's surface (Geiger 1965). These environmental variables, which include temperature, light, wind speed, and moisture, have been critical throughout human history, providing meaningful indicators for habitat selection and other activities. For example, for 2600 years the Chinese have used localized seasona...
Ship recycling has been playing as a catalyst role for the economy of Bangladesh by supporting steel industry, shipbuilding industry and other industries and it has also been generating huge employments for the country. But, existing problems of this industry in terms of safety, health and environmental issues bring negative image for the country sometimes. This paper is aimed to identify the u...
Exotic species dominate many communities; however the functional significance of species' biogeographic origin remains highly contentious. This debate is fuelled in part by the lack of globally replicated, systematic data assessing the relationship between species provenance, function and response to perturbations. We examined the abundance of native and exotic plant species at 64 grasslands in...
