Abstract: One of the least utilized by-products of food industry, despite the great potential that is described, is the whey, which is obtained as a by-product of the technological process production of cheese and casein. The excess whey, which occurs in this process in very high yields, with failure to processing is becoming a very big polluter, what is completely at odds with the potential that such materials possess. On the other hand, the modern tempo and way of life, and increasingly polluted environmental also, impose the need to produce food products that would help the human body in the fight against harmful agents which are exposed to daily. One of the more effective solution is the production of fermented functional beverages based on whey, which achieved this intention in the most natural and most comfortable way. Considering the rather untapped potential of whey as a raw material and growing food shortages in the world market, the aim of this study was to analyze the possibilities of production of functional beverages based on whey, with satisfactory sensory characteristics, in order to demonstrate the attractiveness of whey as raw material in the food industry. This paper presents an overview of the wide possibilities for the use of whey with a special emphasis on its attractiveness and the necessity of its utilizing.

Abstract: Dois experimentos foram conduzidos com o objetivo de avaliar a utiliza o da farinha de varredura de mandioca (FVM), variedade fibra, para coelhos em crescimento. No ensaio de digestibilidade, foram utilizados 22 coelhos com 50 dias de idade, distribuídos em umdelineamento inteiramente casualizado com dois tratamentos e 11 repeti es. Foram utilizadas duas ra es, uma referência e um teste, na qual a FVM substituiu 25% da matéria seca da ra o referência. Os teores digestíveis de matéria seca, proteína, FDN, FDA, energia e amido, com base na matéria seca, foram respectivamente de 85,87%, 1,43%, 2,82%, 0,91%, 3.562 kcal/kg e 63,95%. No experimento de desempenho, foram utilizados 180 coelhos de 35 a 70 dias de idade.Os coelhos foram distribuídos em um delineamento inteiramente casualizado com seis tratamentos (seis níveis de inclus o da FVM: 0%, 20%, 40%, 60%, 80% e 100%, em substitui o à energia digestível do milho) e 15 repeti es com dois animais por unidade experimental. Os resultados permitiram concluir que a FVM pode ser incorporada às ra es de coelhos em crescimento em 26,4%, substituindo 100% a energia digestível do milho. The study aimed to evaluate the effect of cassava root meal on the growth of rabbits. Two experiments were carried out. Digestibilityassay was conducted using 22 rabbits with 50 days of age, in a randomized design, with two treatments and 11 replications. Reference and test diets were used in which CM substituted 25% of the control diet dry matter. The digestible dry matter values, protein, neutral detergent fiber (NDF), acid detergent fiber (ADF), energy and starch, on dry matter basis, were 85.87%, 1.43%, 2.82%, 0.91%, 3,562 kcal/kg and 63.95%, respectively. In the performance trial, 180 rabbits of35 to 70 days of age were used. The rabbits were distributed in a completely randomized design, with six treatments (six levels of CM inclusion: 0, 20, 40, 60, 80 and 100%, replacing the corn digestible energy) and 15 replications, with two animals per experimental unit. Results show that the CM can be incorporated in the growing rabbits rations in 26.4%, replacing 100% of the corn digestible energy.

Abstract: the objective of this trial was to evaluate the effect of babassu meal addition on chemical composition and fermentative characteristics of sugar cane silages. the addition of three concentrations of babassu meal (0; 15 and 30% in fresh matter) was evaluated in a completely randomized design with four replicates. as experimental silos 12 plastic buckets were used, provided with filter closing to allow the exit of fermentation gases. after 45 days, the silos were opened and samples were taken for the determination of dry matter (ms), crude protein (pb), neutral and acid detergent fibers (fdn, fda) and hemicelluloses (hem) content, ph values, total acidity quantification (att), losses by gases (pg) and effluents (pe). the addition of babassu meal increased the ms contents (38.4% e 40.6%), pb (7.8 e 8.9%), fdn (68.8% e 70.9%) and fda (43.0% and 45.1%), respectively, with the addition of 15 and 30% of the by-product. the ph values, averaged 4.4, were not affected by the addition of babassu meal. the percentage of att increased 89.2%. pg and pe were reduced in 44.8 and 58.8%, respectively. the addition of babassu meal have contributed to the improvement of fermentative parameters and the concentration of cp in the sugar cane silages. however, its use as additive becomes limited due to the increase in fiber content that provides to the silages, depreciating its nutritive value.

Abstract: this work aimed to study weed response to fusel oil rate applied at early and late post-emergence. the following species were studied at late and early post-emergence: ipomoea hederifolia, ipomoea quamoclit, euphorbia heterophylla, digitaria spp., cenchrus echinatus and panicum maximum.. the experiment was arranged in a completely randomized design with six treatments and four replications. fusel oil, an alcohol distillation byproduct, was applied at rates of 50, 125, 250, 375 and 500 l ha-1 , plus control without application. the plots were constituted by polyethylene containers with 3 l capacity, filled with topsoil land from a fallow area. visual symptoms of intoxication were verified at 7 and 30 days after application (daa) and dry weight at 30 daa. the variables were submitted to variance analysis according to the design,adjusting the data to obtain the dose-response curve by polynomial regression. the studied species were susceptible only to the application of 500 l ha-1 of fusel oil at early or late plant post-emergence. the species digitaria spp. was susceptible and e. heterophylla tolerant to fusel oil applied at early post-emergence, while the other species were moderately tolerant. e. heterophylla was susceptible, digitaria spp., c. echinatus and p. maximum moderately tolerant and i. hederifolia and i. quamoclit tolerant to fusel oil applied at late post-emergence.
Dust Suppression with Glycerin from Biodiesel Production: A Review  [PDF]
Wei Yan, S. Kent Hoekman
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.32027
Abstract: An increasing number of countries and areas in the world suffer from either natural or anthropogenic dust, which results in a serious hazard with respect to the environment and to personal health and safety. This paper reviews and summa- rizes open literature involving the use of glycerin in dust control applications. Glycerin, a by-product from biodiesel manufacturing, has been evaluated for dust suppressant performance when applied alone as aqueous solutions, or in combinations with surfactants, polymers, or other chemicals. There are reports indicating that glycerin is effective in some dust suppression applications, although details about its use and performance metrics are generally lacking. Re- cent growth of the biodiesel industry has significantly increased the supply of crude glycerin, making it an economically attractive material for use in dust suppression. This paper also highlights several environmental accidents caused by irresponsible discharges of crude glycerin, and points out the need to understand environmental consequences of gly- cerin and its impurities when used in dust suppression applications.
