Optical fibre carbon dioxide (CO₂) sensors are reported in this article. The principle of operation of the sensors relies on the absorption of light transmitted through the fibre by a silica gel coating containing active dyes, including methyl red, thymol blue and phenol red. Stability of the sensor has been investigated for the first time for an absorption based CO₂ optical fiber sensor. Influ...

Red clay contains solid aluminosilicate has been shown to be reactive in the presence of an alkaline activator. The addition coal fly ash and lime improvements their mechanical physical properties geopolymer products. FTIR analysis SEM images product have formation gel geopolymeric product. maximum compressive strength products GP-RFL was achieved 15.92 N/mm2 having water absorption 10.47 % bul...

Rice noodles is a common food, but it faced with the characteristics of hard texture and poor nutrition after aging. Quinoa rich in dietary fiber nutritious can enrich color taste rice noodles. In this paper, red quinoa used as an additive, gelatinization time, added amount, water are selected influencing factors on single factor basis, hardness gel response value to carry out experiments optim...

The membrane-bound form of phosphatidylinositol-4-phosphate (PtdInsP) kinase was purified 4,300-fold from human red blood cells to a specific activity of 117 nmol min-1 mg-1. Although this enzyme copurified with red blood cell membranes, it was solubilized by high salt extraction in the absence of detergent indicating that it is a peripheral membrane protein. The major protein seen in the most ...

Systemic insecticides and application methods were evaluated in two trials that began in 2005 and 2006 for control of potato leafhopper (Empoasca fabae [Harris]) on four red maple (Acer rubrum L.) cultivars and rated annually through 2007. Treatments evaluated in this study included surface drenches of imidacloprid plus cyfl uthrin (Discus) or imidacloprid plus bifenthrin (Allectus SC), clothia...

BACKGROUND: Testing for drug-dependent antibodies (DDA) is traditionally performed in test tubes either with drug-treated RBCs or in the presence of drug. Gel microcolumn and solid phase red cell adherence (SPRCA) methods were evaluated for detection of DDA with and without drug. STUDY DESIGN AND METHODS: Forty-nine frozen DDA samples tested by tube methods were selected. Samples were tested wi...

Casein is a family of milk proteins that exists in several molecular forms and is the main protein present inthe bovine milk. The B variant of bovine k-casein is reported to be favorable for quality and quantity of cheese derived from milk and considered to be included in breeding strategies of dairy cattle. Genotypes of72 Russian Black Pied and 80 Red Pied cows were determined for ...

In this study, to mimic the mineral and organic components of natural bone, hydroxyapatite[HA] and gelatin[GEL] composite scaffolds were prepared using the solvent-casting method combined with a freeze drying process. Glutaraldehyde[GA] was used as a cross linking agent and sodium bisulfite was used as an excess GA discharger. Using this technique, it is possible to produce scaffolds with mecha...

This overview describes two groups of nonimmune hereditary hemolytic anemias caused by defects in membrane proteins located in distinct layers of the red cell membrane. Hereditary spherocytosis (HS), hereditary elliptocytosis (HE), and hereditary pyropoikilocytosis (HPP) represent disorders of the red cell cytoskeleton. Hereditary stomatocytoses represents disorders of cation permeability in th...

Nano hexagonal wurtzite ZnO has been prepared on zeoliteA by the sono-chemical method. The zeoliteA was mixed into Zinc gel, after stirring for two days, the mixture was irradiated 30 min by ultrasonic probe. The filtrated composite gel was calcinated at 500°C for 3h in furnace. The produced composite was characterized using X-ray diffraction, FT-IR spectroscopy and field emission scanning elec...
