The need for a long-term sustaining of optimal concentrations of applied pesticides in the soil in agriculture resulted in the development of systems for controlled release of active substances. Such systems are based on the use of eco-friendly carrier ma... see more

The results of electrophysiological studies of the quantal release features of glutamate in hippocampal neurons' synapses in long-term depression of synaptic transmission are presented.To research the topic, weused the primary culture of the rat hipp... see more

Until now the widley used predictive long-term hazard models of the most intense natural phenomena do not yield predictions other than the mean return period, which indicates only a mean recurrence time, but does not allow any time prediction of the of oc... see more

Fumarole temperatures are the ultimate results of many processes that are encountered by deep fluids during their passage to the surface. Here, the time variations of high-temperature fumaroles acquired by continuous monitoring are presented, to show the ... see more

In present study, a novel galantamine hydrobromide sustained-release capsule was prepared with the extrusion-spheronization method and the optimized preparative formulation. The release studies were performed using marketed capsules (Razadyne ER) as a ref... see more

Background: The major portion of lead in the body resides in skeletal system. The bone turnover affects the release of lead into the circulation from bones. The bone turnover biomarkers (BTM) in lead-battery workers with long-term exposure to lead have no... see more

Gastro retentive dosage forms have potential for use as controlled-release drug delivery systems. Multiple unit systems avoid the “all-or-none gastric” emptying nature of single-unit systems. A controlled release system designed to increase its residence ... see more

The impact of agricultural intensification on soil degradation now is occurring in tropical countries. The objective of this study was to determine the effect of long-term tillage and N fertilization on soil properties and crop yields in corn-soybean rota... see more

Intelligent computing tools based on fuzzy logic and artificial neural networks have been successfully applied in various problems with superior performances. A new approach of combining these two powerful tools, known as neuro-fuzzy systems, has increasi... see more
