this study was intended to evaluate the quality of 30 honey samples, in terms of physicochemical properties such as moisture content, electrical conductivity, ash content, reducing sugars and sucrose, free acidity, ph, diastase activity, and hydroxymethylfurfural (hmf) content. moreover, three methods recommended by the international honey commission for the determination of hmf, including 1) h...

this study investigates removing ash and pyrite sulphur from bitumen by column flotation process. central composite design (ccd) of response surface methodology (rsm) was applied for modeling and optimization of the percentage of ash and pyrite sulphur removal from bitumen. the effects of five parameters namely the amounts of collector and frother agents, particle size, wash water rate and feed...

Background and objectives: Tapinanthus globifer is a semi-parasite plant that mostly grows on the branches of the host tree species of the genera Vitellaria, Kola, Citrus, Combretum, Acacia, and Terminalia. The leaf is known for its use in traditional medicine to treat inflammations, malaria, headaches, bacterial infections, ulcers and diabet...

saffron flower (crocus sativus) is one of the most precious spices in the world. in this respect, thesaffron style samples were gathered from the farms of torbat-heidariyeh located in south khorasanprovince during one year and their preparation was performed based on the common manufacturingstandards. then, in order to considering the international and national standards for saffron and spicese...

Skeletal integrity in meat-type chickens is affected by many factors including rapid growth rate, nutrition and genetics. To investigate the genetic basis of bone and mineral metabolism, a QTL detection study was conducted in an intercross between two lines of meat-type chickens divergently selected for their high (D +) or low (D -) digestive efficiency. Tibia size (length, diameter, volume) an...

The proportion of the leaf blade, leaf sheath and stem fractions in six rice straw varieties averaged 30, 40 and 30%, respectively. In vitro dry matter digestibility (IVD) of these fractions, estimated by the cellulase-neutral detergent solution procedure, was 503, 513 and 610 g/kg, respectively. The lower IVD of the blade and sheath was due to lower degradation parameters estimated by a simple...

The uranium content of several human tooth, bone and soft tissue samples was determined by the fission tract method. The average uranium content in teeth, bones and soft tissues were 6.7, 8.4 and 64 ppb ash, respectively. The distribution of uranium in bones is less uniform than that of teeth, and the uranium content of soft tissues is generally higher than that of teeth and bone. The presence ...

BACKGROUND Legumes are a good source of protein, and are also abundant in carbohydrates, B-group vita-mins, dietary fibre and mineral compounds. MATERIAL AND METHODS This work evaluates the retention of ash, eleven minerals and two heavy metals in products obtained from two common bean cultivars harvested before reaching full maturity, with a dry matter content of about 40%. Analyses were con...

The mean bone pyrophosphate was 0.360 +/- 0.15 mg/g in 8 controls and 1.22 +/- 1.39 mg/g bone in 27 uremic patients (P less than 0.0025). 13 of the 27 uremic patients had bone pyrophosphate levels greater than 2 SD above control values. The ash content of uremic bones with increased pyrophosphate levels (group II) was 56 +/- 9% as compared to 64 +/- 2% in control bones (P less than 0.01) and 60...
