RFID based automatic fair price shop is novel approach in public distribution system (PDS) useful for more efficient, accurate, and automated technique of ration distribution. Public distribution system also called rationing distribution system is one of the wide controversial issues that involve malpractices. The present ration distribution system has drawbacks like inaccurate quantity of good...

< p>Mg-Fe bi-metal oxide was prepared and utilized as a magnetized renewable solid base catalyst for formation of 2-aminothiophenes by means of Gewald’s reaction. The prepared heterogeneous basic solid catalyst can be separated by a magnet and reused without considerable wastage in this activity. The structure of the aforementioned magnetized basic nano-catalyst was studied by XRD (X-ray diffra...

a new nano-sized cobalt(ii) coordination polymer, (col1).0.5dmf.1.5ch3oh(1); [h2l1 = 5-(4-carboxy phenyl azo) salicyilic acid] has been synthesized by a sonochemical method. the thermal stability of compound 1 was studied by thermo- gravimetric and differential thermal analyses. nano-structure of this coordination polymer was characterized by elemental analyses, ir spectroscopy,  powder x-ray d...

The objective of the present work was to investigate the influence of four diets on population growth, development, total length, dry weight, and nutritional value of two zooplanktonic species, Moina micrura and Diaphanosoma birgei. The four dietary treatments were: algae alone (A); algae + vitamins (AV); algae + ration (AR); and algae + ration + vitamins (ARV). Growth rate peak for both specie...

Relationships between somatic growth (length and weight) and two indirect measures of growth (otolith growth, RNA/DNA ratio) were assessed for red drum (Sciaenops ocellatus) under different feeding rations [0%, 2.5%, 5%, 10%, 15%, and 20% body weight (BW)/day] for 30 days. Representative samples from each ration level were taken in 10-day intervals between Day 0 and Day 30 for evaluation of dir...

Sequential observations of the light and scanning electron microscopic appearances and labeling index of rat urinary bladder epithelium following freeze ulcérationwere performed for 8 weeks, and the effect of sodium saccharin on this process when fed as 5% of the diet, beginning either immediately or 2 weeks after ulcération, was investigated. All rats treated with freeze ulcérationof the bl...

the effect of temperature on the main feeding parameters of mnemiopsis leidyi from the southern caspian sea was studied in 2002. the clearance rates and daily rations were estimated from laboratory experiments in a wide range of temperatures from 12 to 27 ?c for m. leidyi of 12?17 mm in length. clearance rate values changed from 52.5 to 107.3 ml ind-1 h-1. the coefficient q10 in temperature 12 ...
