Root-knot nematodes (RKNs, genus Meloidogyne) are a class of plant parasites that seek out and infect the roots many species. The identification RKN attractants can be used in agriculture conjunction with nematode-trapping technology to redirect movements eventually reduce their prevalence field. Here, we discovered some commercial silica gels attract nematodes. Silica contain calcium sulfate. ...

The conventicnal sulfate determination by gravimetrically precipitating barium sulfate is very tedious and time consuming. The present technique uses an ion exchanger so the sulfate can be titrimetrically determined as sulfuric acid. An analysis can be completed in 30 minutes. This method is being used for the routine analysis of sulfate in mixtures of gypsum, anhydrite, calcium oxide, and calc...

Abstract— SDAWS (Spray drying absorption waste sludge) and BFA (bag filter ash), which are the wastes generated in the SDA (pray drying absorption) process, are only partially recycled as cement additives, gypsum boards, building materials, and the rest are being landfilled in managed landfills. However, wastes that have not been disposed of at the landfill are accumulated around the landfill. ...

OBJECTIVE To evaluate the biocompatibility and the setting time of Portland cement clinker with or without 2% or 5% calcium sulfate and MTA-CPM. MATERIAL AND METHODS Twenty-four mice (Rattus norvegicus) received subcutaneously polyethylene tubes filled with Portland cement clinker with or without 2% or 5% calcium sulfate and MTA. After 15, 30 and 60 days of implantation, the animals were kill...

From the carbohydrate-protein linkage region of whale cartilage proteoglycans, which bear predominantly chondroitin 4-sulfate, one nonsulfated, two monosulfated and one disulfated hexasaccharide alditols were isolated after exhaustive digestions with Actinase E and chondroitinase ABC, and subsequent beta-elimination. Their structures were analyzed by chondroitinase ACII digestion in conjunction...

In regenerative approaches, scaffolds play a crucial role in defining the 3-D anatomical shape and microenvironment for cells, while maintaining space, favoring regeneration of new bone, preventing soft tissue migration bony lesion. A variety materials have been explored as bone regeneration. Metals are generally inappropriate such applications because they lack desired degradability biological...

Alkali-activated slag is commonly used as a cement substitute to reduce the environmental footprint of construction materials. Nonetheless, use significant amount alkaline activators, such sodium silicate or hydroxide, can be detrimental in terms global warming potential impact. The aim this work complementary activators partial replacement and therefore activated binder. Calcium calcium carbon...

The aim of current study was the validation of TLC densitometric method for identification and determination of Estradiol hemihydrate in dosage forms. The TLC conditions were: glass plates with Silicagel G60F254; mobile phase: chloroform : water = 90 : 10 v/v. Linearity accordance between the concentration and spot area in range: 5.10-4 g/ml ÷ 5.10-3 g/ml is proved by the regression equation: y...

BACKGROUND AND OBJECTIVES Magnesium sulfate has been shown to benefit asthmatic children and adults with poor responses to initial beta-agonist therapy and systemic corticoids in the emergency department. The aim of this study was to realize a no systematic review about the treatment of the acute asthma with intravenous and nebulized magnesium sulfate in the emergence. CONTENTS The first inve...
