Intestinal calcium absorption was investigated in an adult frog (Rana esculenta) by injecting a CaCl2 solution containing 45Ca into the lumen. The 45Ca absorption coefficient in the proximal loop was higher than in the distal loop, only when the CaCl2 solution was left for 4 h. This coefficient increased both in the proximal and distal loops when a 4-h treatment was substituted for a 1-h treatm...

green olive cultivars “manzanila” and “mission” were harvested at the mature green stage. they were either treated with 1-methylcyclopropane (1-mcp) at a concentration of 1.8 µl/l for 24 h at 20°c or kept untreated as a control. both treated and untreated fruits were then immersed in water containing cacl2 of 0 (control), 50 and 100 mm for 2 h under 1.2 bar pressure. fruits were then surface dr...

A simple approach to the evaluation of blood coagulation using a microfluidic paper-based lateral flow assay (LFA) device for point-of-care (POC) and self-monitoring screening is reported. The device utilizes whole blood, without the need for prior separation of plasma from red blood cells (RBC). Experiments were performed using animal (rabbit) blood treated with trisodium citrate to prevent co...

Atrazine is an agricultural herbicide used in large quantities and consequently companied with its two degradation products, deethylatrazine (DEA), and deisopropylatrazine (DIA), are commonly detected in groundwater and surface water. The retention of these compounds in vadose zone is highly related to their adsorption to soils. Laboratory studies were conducted to determine the sorption behavi...

The average ionic strength of 20 West Australian soils was found to be 0·0048. The effects of three electrolytes (deionized water, CaCl2 and KN03), three ionic strengths (0'03. 0·005 and soil ionic strength at field capacity, Is) and two soil liquid ratios (1:5 and 1:10) on the pH of 15 soils were investigated. pH measurements in solutions of ionic strength 0·005 differed the least from measure...

Composite particles with multifunctions have been extensively utilized for various applications. Bubble particles can be applied for ultrasound-mediated imaging, drug delivery, absorbers, cell culture, etc. This study proposes a one-step strategy to obtain Pt nanoparticles loaded in alginate bubbles. A needle-based droplet formation was used to generate uniform alginate particles about 2 mm in ...

Some of the ultrastructural (freeze-etching technique), morphological, and biochemical effects of Sendai virus interaction with chicken erythrocytes have been studied under fusogenic (in the presence of CaCl2) and nonfusogenic (in the presence of ethyleneglycol-bis-N,N'-tetraacetic acid, [EGTA]) conditions. The following phenomena occur, irrespective of the presence of CaCl2 or EGTA: (a) bindin...

The present study is to elucidate and efficacy of Ultra-fine slag Calcium Chloride in improving the Engineering characteristics expansive soil. An experimental program has evaluated effects 3%, 6%, 9% CaCl2 0.25%, 0.5%,  1.0%, Free swell index, swelling potential, pressure, plasticity, compaction, strength, hydraulic conductivity, Cation Exchange Capacity microstructural XRD, SEM tests soil als...

Homogenous ZrCxOy powders have been successfully synthesized by in-situ electro-reduction of solid ZrO2–C composite precursors in molten CaCl2. The effect applied cell voltage and molar ratio ZrO2 to C on preparation were investigated. reduction pathway the electrode was studied based analysis intermediate products using X-ray diffraction (XRD) scanning electron microscopy (SEM). results show t...
