Offset pulse position modulation (OPPM) and Dicode (DiPPM) have been introduced as new attractive techniques, however, they are suffering from erasure, wrong slot, false alarm errors. in this paper, two types of error correction (EC) codes, Low-Density Parity Check (LDPC) code Reed Solomon (RS) code, where paired the OPPM DiPPM systems to reduce bugs, analyze best EC parameters, choose superlat...

in the present study, the concentrations of three heavy metals including lead (pb), zinc (zn) and arsenic (as) in 72 different honey samples collected from north-western regions of iran were investigated using atomic absorption spectroscopy method. all metals were detected in 88.88% of the honey samples. the range of metals contamination in honey samples was 0.01 to 11.09 ppm. zn was the most a...

Lake Victoria, which is the largest fresh water lake in Africa, represents a unique ecosystem that has the largest fresh water fishery in the continent. However, increased anthropogenic activities has increased the potential pollution of the lake especially the heavy metal pollutants which may be toxic to humans and aquatic fauna. There is need therefore for continuous monitoring of pollution l...

–A study was study wasundertaken to investigate the effect of graded levels of inorganic Zn (zinc carbonate) on growthperformance and oxidative defense mechanism inweaned female Sprague Dawley rats for experimental duration of 16 weeks.Ninety weaned rats (93.83 ± 1.308g Bwt) were randomly allotted to 30 replicates with 3 rats in each replicate which were in turn randomly allotted to 5 dietary t...

PURPOSE To estimate the overall effect of 1000 ppm F relative to 250 ppm F toothpaste. METHODS Experimental caries increment studies from the dental literature, which compared 1000 ppm with 250 ppm fluoride toothpastes, were summarized using meta-analytic methods. RESULTS The overall caries reduction of 1000 ppm F relative to 250 ppm F paste was estimated to be 0.142 (95%-CL: 0.074-0.210) w...

BACKGROUND Herbal products of questionable quality create major concern for human population since their production is often not controlled and regulated. MATERIAL AND METHODS Antihypertensive herbal products were subjected to pharmaceutical quality control parameters specified in Pharmacopoeias, toxic quantification of heavy metals by flame atomic absorption spectrophotometer and adulterated...

an experiment was conducted to investigate the effect of zinc (zn) supplementation and different concentrations of calcium (ca) and phosphorus (p) in wheat-based diets on the performance, immune responses and bone parameters of broiler chickens. a randomized complete block design with factorial arrangement was used (three concentrations of zn supplementation×two concentrations of dietary ca-p),...

A total of 360 barrows (DNA 600 × 241; initially 12.1 ± 0.07 lb) were used in a 38-d growth study to evaluate the effects including folic acid (Rovimix Folic Acid, DSM, Parsippany, NJ) with or without pharmacological levels Zn provided by zinc oxide (ZnO) on performance and fecal characteristics nursery pigs. Pigs weaned at approximately 19 d age randomly allotted 1 6 dietary treatments. 72 pen...
