Effects of wastewater discharge on the coastal area in Gaza strip Palestine are not fully investigated. This study investigated effect physical and chemical properties marine water over a period 2 year. Sea sediment samples were collected from about 20 different sites. The sediments wastewater/sea mixing zone at depth 0, 2.5 5 m column direct discharging pipe line location similarly other locat...

Human serum albumin (HSA) is an important protein that carries variety of substances like some hormones and drugs in blood. Pharmacological studies of the interaction of many drugs and HSA are reported during several decades, specially recently years. Interaction of cortisol and fluoxetine hydrochloride (FLX) (as a common anti-stress drug) with HSA (as their carrier in blood) has been studied s...

AIM To determine the pH of pus collected from periapical abscesses. METHODOLOGY Forty patients (Male = 17/Female = 23) between the ages 17 and 37 years, each with a periapical abscess and with no relevant medical history, were recruited. All the participants had moderate-to-severe pain on percussion accompanied by localized or generalized swelling. At least 1 mL of pus was aspirated from each...

The studies of Gorter (1), Hughes and Rideal (2), Neurath (3), and Langmuir (4) have shown that proteins are capable of forming surface films of a thickness and area independent of the diameter of the molecule. Depending on the pH and salt concentration of the solution upon which the protein is spread, the surface area may be more than 5 times greater than that to be expected from a monolayer o...

In wastewater, biological phosphate removal can fail because of the presence of glycogen accumulating organism (GAO), therefore measuring glycogen stored in microbial cultures provides information on the bacterial population type. Once glycogen is hydrolysed to glucose it was accurately measured using a human glucose meter. The standard curves demonstrate linearity regardless of the pre-treatme...

This work describes a general methodology for enhanced enzyme-linked immunosorbent assay (ELISA) that integrates enzyme-coated microparticle probes for robust yet highly efficient signal amplification and a handheld pH meter for a simple, portable, quantitative readout. Its utility is well demonstrated with the detection of the target protein with a 14-fold enhancement of sensitivity in compari...

ABSTRACT The objective of this study was to determine pH and the concentrations Calcium (Ca2+), Magnesium (Mg2+), Chloride (Cl-), Sodium (Na+), Potassium (K+) (Ca2+) in mammary gland secretion pre-foaling Mangalarga Marchador (MM) mares best method predict parturition breed. Forty-two pregnant MM were evaluated once daily from 310 days gestation until parturition. Mammary pH, measured by meter ...

A procedure for extracting plasmid DNA from bacterial cells is described. The method is simple enough to permit the analysis by gel electrophoresis of 100 or more clones per day yet yields plasmid DNA which is pure enough to be digestible by restriction enzymes. The principle of the method is selective alkaline denaturation of high molecular weight chromosomal DNA while covalently closed circul...

The formaldehyde-sulphite clock reaction was studied using an Orion SA 720 pH/ISE meter interfaced to an IBM PC. The laboratory software 'ASYST' was employed to facilitate data acquisition and data treatment. Experimental pH profiles thus obtained for the first time were simulated by invoking a theoretical model based on the reaction mechanism suggested by Burnett [1]. The variation of rate con...
