Background: Hypertension is the third risk factor for the cardiovascular diseases. This study investigated the effects of mineral water from Damavand spring on the blood pressure and serum lipid profiles in men with hypertension. Methods: In this study 41 hypertensive men were randomly assigned to Damavand mineral water (DM) and Tehran water groups (TW). The DM and TW received 1.5-liter bottle ...

The rendering industry collects and safely processes approximately 25 million t of animal byproducts each year in the United States. Rendering plants process a variety of raw materials from food animal production, principally offal from slaughterhouses, but include whole animals that die on farms or in transit and other materials such as bone, feathers, and blood. By recycling these byproducts ...

The aim of this study was to evaluate the microbiological quality of different commercial mineral water brands, wells and reservoir supplies in surrounding areas of the city of Marília, Brazil, to determine the amount of total and fecal coliforms. Eighteen samples of each source (mineral and reservoir supplies) were analyzed using Colilert Technique in cellophane. The results revealed that one ...

The phosphate industry is a major contributor to the economy of some Mediterranean countries (i.e. Morocco, Jordan, Tunisia, etc). Large volumes of water are required by the mining industry from areas where water resources are scarce or limited. Water scarcity may be worsened by a degradation of the water quality after phosphate processing. The pressure on water is liable to hamper the developm...

This paper defines the concept of organic and conventional agriculture presents differences in quality produced food resulting from farming system. The test materials were same groups products certified production. As a result, dry matter content, water activity content potassium, iron, copper, manganese lead compared. obtained results showed that is characterized by higher lower activity. Conv...

Ground granulated blast furnace slag is widely used as a mineral admixture to replace partial Portland cement in the concrete industry. As the amount of slag increases, the late-age compressive strength of concrete mixtures increases. However, after an optimum point, any further increase in slag does not improve the late-age compressive strength. This optimum replacement ratio of slag is a cruc...

The metal mining industry faces many large challenges in future years, among which is the increasing need to process low-grade ores as accessible higher grade ores become depleted. This is against a backdrop of increasing global demands for base and precious metals, and rare earth elements. Typically about 99% of solid material hauled to, and ground at, the land surface currently ends up as was...
