in this paper, the effect of two domestic seeds hydrocolloids (basil seed and sage seed gums) and one commercial hydrocolloid (pectin) on characteristics of non-fat concentrated yoghurt was studied. for this purpose, effect of different concentrations of these gums (0.05, 0.1, 0.15 and 0.2%) on physicochemical and sensory properties after 1 and 7 days were investigated and compared with control...

The shrinking water supply together with our continuously increasing demand for this resource has stimulated a renewed interest in reverse osmosis (RO) as a water treatment unit process. A wider use of RO membranes, however, is impeded by a group of phenomena that lead to permeate flux decline, deterioration of permeate water quality, shortening of membrane life, and thus to a substantial incre...

We describe a series of stringent relationships between abundance, solubility and chaperone usage of proteins. Based on these relationships, we show that the need of Escherichia coli proteins for the chaperonin GroEL can be predicted with 86% accuracy. Furthermore, from the observation that the abundance and solubility of proteins depend on the physicochemical properties of their amino acid seq...

As indicated by its title, the book ‘Chemistry for Environmental Scientists’ aims at covering a very broad field of knowledge. After a short and general introduction, it is divided in four chapters, namely ‘Chemistry under environmental conditions’, ‘Fundamentals of physical chemistry’, ‘Chemistry of the elements and its [sic] compounds in the environment’ and ‘Chemical processes in the environ...

The cutting, lay-up and bagging of out-of-autoclave (OOA) prepregs for composite part fabrication can take from several days to weeks, depending on the desired part size. This period of ambient temperature “out-time” induces resin polymerization/cross-linking, and affects critical physicochemical phenomena such as minimum viscosity, gelation, and vitrification. Therefore, the capability to moni...

high nutritional value and existence of bioactive components in sesame seeds converted it to a valuable food. one of the methods to increase per capita consumption is processing of sesame with different ways such as production of sesame milk. in this study, the effect of blanching time (0 as a control sample, 15 and 30 min) at 95°c and roasting temperature (0 as a control sample and 145°c) for ...

Orchids are used worldwide for indoor decoration, vanilla production, and beverage preparation. They are also reported for their therapeutic efficacy in brain-related problems. The in vitro micropropagation technique was used for their propagation using the orchid maintenance/replate (OMR) medium. The current study was based on analysing the effect of biofield energy treatment on the physicoche...
