The role of water in carbon feed on the surface-guided growth of horizontally aligned single-walled carbon nanotubes (HA-SWCNTs) was investigated. It is shown that the amount of water can be optimized to favor HA-SWCNT growth, which is proposed to be due to selective etching of carbon deposits at carbon–metal interface. Without water, nanotube–nanotube interaction and carbon accumulation at the...

s of papers 47 tered via water, in preventing necrotic enteritis (NE) in broilers and reducing fecal bacteria. The NE challenge model included: 200,000 Eimeria acervulina oocysts/bird 5d and Clostridium perfringens (CP) 7d posthatch. Healthy, newly-hatched broiler male chicks (Ross x Cobb commercial source) were randomly placed into wire floor cages. Treatments included positive non-infected co...

honey bees as other animal creatures require water and nutrients, including carbohydrates, proteins, fats, vitamins, minerals and water for their maintenance, growth and reproduction. they normally obtain their nutritional requirements from flowers, but at times when there aren,t sufficient flowers available(fall, late winter and early spring) they need supplemental feeding to prevent their bei...

Feed costs typically represent more than 50% of total costs of producing milk on a dairy farm. Feed cost savings, even a few dollars per ton, add up to significant savings over a year on a large dairy. For many dairies, a ration-balancing software program that uses linear programming techniques can be used to determine the opportunity cost or price of including a new feed in a ration. However, ...

The aim of the present work was to determine whether the administration of melatonin or L­-tryptophan (a precursor of melatonin) affects the immune responses and performance of broilers during induced exposure to aflatoxins in feed. The study was conducted from 0-6 weeks comprising six dietary treatments in triplicate with10 chickens in each replicate. The diets were formulated to supply 23% cr...

Background: Considering the carcinogenic effects of heavy metals, such as chromium, it is essential to remove these elements from water and wastewater. Direct osmosis is a new membrane technology, which can be a proper alternative to conventional chromium removal processes. Methods: The wastewater samples were collected from an electroplating unit, located in Alborz industrial city, Qazvin, Ir...

Semi-intensive shrimp production in Honduras is based upon use of formulated diets to supply nutrients for shrimp growth. Unconsumed feed contributes nutrients to pond water, which when discharged may deteriorate water quality in receiving waters. This experiment focused on the development of nutrient budgets (nitrogen and phosphorus) in semi-intensively managed shrimp ponds receiving a low or ...

Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...

The potential of recirculating aquaculture systems (RAS) in the aquaculture industry is increasingly being acknowledged. Along with intensified application, the need to better characterise and understand the accumulated dissolved organic matter (DOM) within these systems increases. Mature RASs, stocked with rainbow trout and operated at steady state at four feed loadings, were analysed by disso...

Arsenic created a serious public health problem in Bangladesh due to its presence in groundwater and dissemination of the toxic effects to millions of people. The scarcity of the treatment options to manage this affected population has made the situation much worse. To find a promising treatment option, this study was undertaken to examine the ameliorating roles of Syzygium cumini leaf extract ...
