To investigate the effect of dietary fluoride (F) on some blood biochemical constituents, twenty male cross-bred calves (aged 6-8 months) were divided into equal groups and fed for 20 weeks on diets of a concentrate mixture and green maize (50:50 for the first 3 months and 40:60 during the later phase). The four dietary treatments differed only with respect to the F content of the mineral mixtu...

In this paper, a method was developed for pre-concentrating large-volume biological samples for subsequent analysis. We previously developed another pre-concentration device, but it unfortunately altered the pH of the sample when an electric field was applied to the sample reservoir. Changes in the pH are not suitable for subsequent antibody-antigen reactions because of the stability issues tha...

In order to determine the concentration of pyrophosphate (PPi) and its subcellular distribution in Chara corallina, a new method to concentrate PPi from cell extracts was developed. PPi was extracted and concentrated as CazPzO, under alkaline conditions. The amount of PPi in the precipitate was measured using an enzyme system containing pyrophosphate:fructose6-phosphate 1-phosphotransferase (E...

OBJECTIVE To perform a comparative analysis of the effects of platelet-rich plasma and centrifuged bone marrow aspirate on the induction of bone healing in rabbits. METHOD Twenty adult, male New Zealand rabbits were randomly separated into two equal groups, and surgery was performed to create a bone defect (a cortical orifice 3.3 mm in diameter) in the proximal metaphysis of each rabbit's rig...

Pendahuluan: Candida albicans merupakan mikroorganisme komensal dalam rongga mulut. Pertumbuhan berlebih dapat dipengaruhi oleh kondisi sistemik maupun faktor lokal. Kondisi seperti penggunaan obat anti hipertensi pada penderita mempengaruhi munculnya gangguan mulut hiposalivasi. Salah satu lokal yang penting adalah kebersihan dengan salah indikatornya terdapatnya lapisan putih dorsum lidah ata...

in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...

sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, t1), 35% wheat straw (t2), 35% barley straw (t3) or 35% maize straw (t4). total-tract apparent digestibility for dry matter, organic matter...

binders are of prime importance in the agglomeration of iron ore concentrates. in this research, strength and density of briquette produced from the magnetite concentrate of gol-e-gohar were investigated using different binders at various applied pressures. the results showed that peridor was the most effective binder relative to bentonite and lime. for all types of binders, the increase in bin...

Abstract The traditional approach for the beneficiation of South African siliceous sedimentary phosphate ores has been reverse cationic flotation. robustness this approach, however, a concern due to its sensitivity parameters such as slimes content, headgrade (P 2 O 5 and SiO content), reagent dosages conditioning times. mineralisation ore body under investigation is predominantly carbonate flu...

Background and Objectives: Red beet extract concentrate can be used as a natural colorant in food products; however, destructive effects of thermal methods to produce juice concentrate decrease nutritional value in the final product. Materials and Methods: In this study, red beet extract was concentrated using osmotic distillation method, and the best pretreatment was evaluated to increase t...
