the objective of this study was the evaluation of ph, color parameters [lightness (l*), redness (a*), yellowness (b*), chroma (c*), hue (h*), a*/b* ratio, and color differences (δe)], mb, metmb, oxymb, deomb and whc in minced meat. three types of meat ( beef, camel and ostrich) and four mincing processes (three using a grinder with 7.5, 4 and 3 mm diameter holes in the plate, and a fourth in wh...

16 Grey model (GM) and artificial neural network (ANN) were employed to predict suspended solids 17 (SSeff), chemical oxygen demand (CODeff) and pHeff in the effluent from conventional activated 18 process of an industrial wastewater treatment plant using simple online monitoring parameters (pH 19 in the equalization pond effluent; pH, temperature, and dissolved oxygen in the aeration tank). Th...

Studies were carried out on a paddy soil fungal isolate identified to be a strain of Aspergillus niger from Manipal. The parameters that largely impact enzyme production viz., fermentation time, impeller speed, pH, temperature and nutrient supplements were studied. Optimization of production parameters for production of protease was done by the single-parameter mode. Casein served as substrate ...

UNLABELLED Regular supply of fluoride ions to the oral environment is one of the prophylactic actions against dental caries. Fluorides, whose exogenous action combines with saliva properties, condition the anticariogenic effect. Fluoride ions exhibit high chemical activity, can alter the oral environment parameters and inhibit the activity of enzymes. PURPOSE In the current study, the effect ...

Lignocelluloses materials were selected for ethanol production, but certain problems occurred, such as the hydrolysis and detoxification process. A biological flocculation technology was to apply for the detoxification of acid hydrolyzate of lignocelluloses materials. Meanwhile chitosan was confirmed as the best biological flocculant which showed good detoxification effect. In order to reach th...

adsorption capacity of 4-chloro-2-nitrophenol (4c2np) onto nano-ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-tio2 dosage, initial ph and initial 4c2np concentration. optimum conditions for 4c2np adsorptionwere found to be initial ph z 2, nano-tio2 closer- 0.01 g and equilibrium time 1 h. the adsorptionkine...

The formation constants (log K), of the complexes formed between a number of amino acids(glycine , L-valine and L-alanine) with p-sulfonatocalix [4] arene at varying temperatures (25± 0.1to 65 ± 0.1 °C) in aqueous solutions and at natural pH of p-sulphonato-calix [4] arene (pH=3.2) bymeans of UV-Vis spectrophotometeric technique have been investigated. At this pH the guestmolecule is in its cat...
