Human interference in production systems becomes feasible through the use of specific devices that, among other functions, allow monitoring, control and optimization processes. One drawbacks encountered sugar ethanol industry is lack instruments for measurement °Brix concentration sugarcane that are low-cost non-destructive. The monitoring cane necessary to identify appropriate time harvesting ...

Integrated anaerobic/aerobic systems have been considered feasible alternatives concerning technical and economic aspects for treating domestic wastewaters. The main modification in the UASB reactor concerns this association with the RAIB. The UASB effluent was distributed through openings along its side walls to the RAIB, allowing the elimination of collecting channels and feeding devices from...

This study was undertaken to evaluate the efficiency of a liquid-solids separation process and microwave pretreatment, as well as anaerobic biodegradability of microwave pretreated dairy manure. Liquid-solids separation of raw dairy manure resulted in solid and liquid fractions having different properties, with the solid fractions richer in total and volatile solids content and liquid fractions...

this study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-d and naphthalene acetamide application on yield and quality of date palm of ‘kabkab’ cultivar. the inflorescences sprayed with 2, 4-d isopropylester (0, 10, and 20 mg l-1), naphthalene acetamide (0, 80, and 120 mg l-1), putrescence and spermidine (0, 0.1, and 1.0 mm), three or six weeks after pollin...

gerbera cut flowers is one of the important and popular cut flowers in the world that regardless of increasing production of this plant in iran, the duration of its life is short due to rapid wilting petals and bending neck of flower. to increase vase life of gerbera cut flowers cv. ‘alain ducasse’, the essences of eucalyptus and rosa damascena, the combination of these two essences at a concen...

Yields on 'Concord' grape (Vitis labrusca L.) increased as pruning severity was decreased until the 6th and last year of this study, at which time the yields tended to equalize between the 30 + 10, 50 + 10, and 70 + 10 pruning treatments. By the last year, vines pruned to the 70 + 10 level produced fruit of unacceptable quality. When the 3-node spurs were shoot-positioned, their productivity wa...

whey contains more than half of total solids present in the original milk, which includes 20% of the proteins, most of the lactose, minerals and water soluble vitamins. in this study, selective separation of whey components by aphron flotation (separation of ultrafine particles by micro-bubbles) has been investigated. it has been shown that it is possible to recover valuable components of whey ...

The study was conducted in Completely Randomized Design (CRD) with 7 treatments replicated thrice. were T1 (pomegranate juice 1ltr + 0.5 g yeast 500 sugar), T2 1g 500g T3 1.5g T4 2g T5 2.5g T6 3g T7 3.5g sugar). pomegranate fermented using Saccharomyces cerevisiae. cider assessed for the physico-chemical changes that occurred throughout its 90 days of storage, as well sensory quality a 9-point ...
