learning ability and memory duration are two inseparable factors which can increase theefficiency of a living organism during its lifetime. trichgramma brassice bezdenko (hym.:trichogrammatidae) is a biological control agent widely used against different pest species.this research was conducted to study the olfactory associative learning ability and memoryduration of t. brassicae under laborato...

Understanding consumer perception of the organoleptic qualities of a food product in terms of rheological properties is a major challenge for food scientists, and has been studied for a long time. As early as 1962 Szczesniak and Farkas (1962) reported a relationship between the mouthfeel of thickened solutions and their rheological behaviour. In this work, thickeners were categorised based on p...

This paper presents a very useful software tool to design, simulate and optimise wastewater treatment plants. The program is called DESASS (DEsign and Simulation of Activated Sludge Systems) and has been developed by CALAGUA research group. The mathematical model implemented is the Biological Nutrient Removal Model No.1 (BNRM1) which allows simulating the most important physical, chemical and b...

A series of gels differing in ionic content was prepared by derivatizing starch with varying amounts of carboxymethyl add-on. Some derivatives were lightly crosslinked with epichlorohydrin to reduce soluble material and increase the amount of gel. The gel fraction of each batch was isolated. and viscosity 1]. shear modulus G. and swelling in water and salt solution were then determined. One gel...

Dysphagia is the medical term for difficulty swallowing. Thickened liquids are often used in the management of dysphagia to improve bolus control and to help prevent aspiration. A range of starches and gums has historically been used to thicken liquids. Although thickened liquids improve swallow safety, they appear to have a great potential for unintended physiological consequences. Initial con...

When developing a diet for citizens with diseases of the gastrointestinal tract or obesity, it is necessary to adhere therapeutic in which bakery products and dairy berry fillers can be wholesome ingredients. In order increase range based on local plant raw materials, physicochemical quality indicators were studied organoleptic evaluation various types thickeners was given.

The rational use of water in the mineral processing industry has become an im-portant issue due to the geographical location of many plants. The increase of capacity in manycopper concentrators has lead to an increased effort for recovering the maximum amount ofwater in the solid-liquid separation process. Thickeners work continuously to produce a con-centrated underflow and a w...
