The aim of this study was to understand the effects of the interaction between aluminium and low pH in a native fish species Prochilodus lineatus. Thus, juveniles of this neotropical fish species were exposed to 196 microg L(-1) of dissolved aluminium in acid water (Al group), only to acid water (pH group) or to water with neutral pH (CTR group) for 6, 24 and 96 h. Al effects were evaluated wit...

there is a worldwide interest in using fibers of different types in concrete mixtures. in this regard, as the use of pet fibers has gradually increased during the last decade, this study aims to investigate the effects of pet fibers on the mechanical properties of hardened concrete and the workability of fresh concrete. to this end, different contents of pet fibers (pc= %0, %0.5, %1 and %1.5) a...

Abstract Drinking water is a sole element of human life. The rapidly growing population adding to the excessive demand for water. Increasing drinking rising over-exploitation Raw sources require treatment with high production capacity treatment. Present research provides case study plant Kekri, Rajasthan, India. In these two plants purification efficiency good as compared conventional plants. A...

Gastric secretion of hydrochloric acid requires protons and chloride, yet the mechanisms and regulation of gastric chloride secretion remain unclear. We developed an in vivo technique to simultaneously measure acid/base and chloride secretion into the gastric lumen of anesthetized rats. The cannulated stomach lumen was perfused with weakly pH-buffered chloride-free solution containing a chlorid...

Deterioration of reinforced concrete is often studied in idealised scenarios where only one exposure environment dominant. For example, to study structures exposed de-icing salt environments, the effect a cyclic wetting and drying regime considered, but deterioration by carbonation not given any emphasis. However, some studies have shown that could result release bound chlorides this lead an in...

The study carried out to evaluate some of the physical and chemical properties ground water samples from west Alshirqat district, Salaheddin province, IRAQ. Six wells selected, sample collected every month for 6 months (October,2021 – March 2022). In each electric conductivity (EC), pH, total dissolved solid (TDS), oxygen (DO), biological demand (BOD), hardness (TH), calcium (Ca H), magnesium (...

It can be said that corrosion of reinforcing steel is a serious problem for concrete structures. However, the mechanism still unclear, and it difficult to prevent perfectly. In this study, in order make clear process alkaline environment, products formed solutions various OH- Cl- concentrations were evaluated by Raman spectroscopy. addition, influence dissolved oxygen on was investigated. Furth...

Waste water treatment reservoirs are contaminated with many hazardous chemicals and acids. Reservoirs typically comprise concrete and reinforcement steel bars, and the main elements responsible for their deterioration are hazardous chemicals, acids, and ozone. Currently, a variety of techniques are being used to protect reservoirs from exposure to these elements. The most widely used techniques...

INTRODUCTION The aim of this study was to investigate the stability of a mixture of temocillin 20mg/ml in 5% dextrose and in 0.9% sodium chloride polyolefin bags after freezing, microwave thawing and long-term storage at 5±3°C. METHODS The stability of ten polyolefin bags containing 20mg/ml of temocillin, five bags in 5% dextrose and five bags in 0.9% sodium chloride, prepared under aseptic c...
