the effect of poultry waste application on physicochemical and biological properties of sandy clay loam soil was investigated on a 7m x 7m plot of land. plot was divided into four portions and 7.5kg each of broiler, cockerel and layers waste was applied to plot a, b, and c in slurry form while plot d was used as control(no application) for eight weeks with two weeks interval. after the fourth a...

milk and dairy products are important components of a balanced diet. milk does have distinct physicochemical, biological and microbial characteristics. the bacterial contamination of milk not only reduces the nutritional quality but its consumption threatens health of the society. in this study, 100 pasteurized milk samples were collected randomly from tabriz city, northwestern and were analyze...

in this project, different nettle plants from north regions of iran including tonekabon, amol and gorgan were collected. the oil was extracted using soxhlet extraction apparatus and was subjected to series of physical and chemical tests and determinations consisting of refractive index, melting point, smoke point, nonsaponifiable matter, iodine value, saponification value, peroxide value, totox...

today, in parallel to growing in acceptance of functional products, various additives are used to improve the characteristics of functional food products. the coenzyme q 10 plays a vital role in cellular energy production. it also increases the body's immune system via its antioxidant activity. the aim of this study was to evaluate the addition of coenzyme q 10 on physicochemical properties of ...

Self-assembly is a ubiquitous physicochemical phenomenon. It is inherent to molecular recognition effects in the biological domain, and thus presents a basis for understanding the constitution and dynamic organization of living beings. However, it is argued in this paper that the very notion of self-assembly presents an incorrect and misleading one for the physical effects that it stands for. S...

wheat starch is the most common type of starch in iran as well as many other parts of the world with enormous applications in food and non-food products. to improve its physicochemical properties or create new functionalities, starch can be modified by changing its molecular structure. amongst different methods for starch modification, physical methods have received more attention recently. pre...

the effects of zinc oxide nanorod (zno-n) incorporation on thephysicochemical properties of tapioca starch / bovin gelatin composite film such as water absorption capacity (wаc), water solubility and permeability to water vapour (wvp) were investigated. in this search, zno-n was homogenized by sonication and added into tapioca starch / bovine gelаtin dispersions аt different concentrations (e.g...

in this study, the effect of mentha piperita essence (mpe) incorporation into cassava films on the hydrophilic and physicochemical properties of the resulting biodegradable films was investigated. the properties included solubility, moisture uptake and contact angle. mpe was added into biodegradable films at different amounts (1, 2 and 3%, w/w total solid). all biofilms were plasticized with 40...
