Discrete element method (DEM) is a numerical technique widely used for simulating the mechanical behavior of granular materials involved in many food and agricultural industry processes. Additionally, this technique is also a powerful tool to understand many complex phenomena related to the mechanics of granular materials. However, to make use of the potential of this technique it is necessary to develop DEM models capable of representing accurately the reality. For that, among some other questions, it is essential that the values of the microscopic material properties used to define the numerical model are accurately determined.

We studied the influence of pre-incubation weight of eggs (EW) laid by 24 wk-old brown laying breeders on egg production from 18 (start of egg production) to 22 wk of age (average egg production across EW treatments of 87.8%). The experiment consisted in 7 treatments based on the initial EW (47 to 53 g with 1 g difference between groups) Average BW of the extreme groups varied at hatching from 32.5 to 35.4 g, respectively. Feed intake, egg production, and egg weight were recorded weekly by replicate as well as for the entire experiment (18 to 22 wk of age). Hens were weighed by replicate at the beginning and at the end of the experiment. From these data, ADFI, egg production, egg weight, egg mass, feed conversion ratio per kilogram of eggs and per dozen of eggs, and BW gain were calculated by week and for the entire experiment. Also, the number of dirty, broken, and shell-less eggs was recorded daily by replicate in all eggs produced. Data were analyzed as a completely randomized design with 7 treatments differing in the initial pre-hatching EW. Effects of EW on the variables studied were partitioned into linear and quadratic components. EW did not affect the age at which pullets reached 50% egg production, cumulative egg production, or BW gain of the hens from 18 to 22 wk of age. Egg weight and the proportion of dirty, broken, and shell-less eggs were not affected by the BW of the pullets at hatching. In summary, small eggs (>47 g) laid by young, healthy laying breeders, can be used successfully to produce high quality pullets

The effects of the inclusion of raw glycerin (GLYC) and raw lecithin, in the diet (23 to 55 wk) on liver characteristics and various serum lipid fractions were studied in brown egg-laying hens at 55 wk of age. The control diets were based on corn, soybean meal, and 4% supplemental fat and contained 2,750 kcal AMEn/kg, 16.5% CP, and 0.73% digestible Lys. The diets were arranged as a 2 3 factorial with 2 levels of GLYC (0 and 7%) and 3 animal fat to lecithin ratios (4:0, 2:2, and 0:4%). Each treatment was replicated 8 times and the experimental unit was a cage with 10 hens. At 55 wk of age, 2 hens per cage replicate were randomly selected, weighed individually, and slaughtered by CO2 inhalation. Liver was immediately removed and weighed and the color recorded by spectrophotometry. In addition, blood samples from one bird per replicate were collected from the wing vein and the concentration of total cholesterol, low and high density lipoprotein cholesterol, and triglycerides were determined. The data were analyzed as a completely randomized design and the main effects of GLYC and lecithin content of the diet and the interactions were determined. No interactions between GLYC and lecithin content of the diets were detected for any of the variables studied. Liver characteristics and serum lipid traits were not affected by the inclusion of GLYC in the diet. The substitution of animal fat by lecithin, however, reduced the redness (a* 14.9 to 13.8) and yellowness (b* 8.60 to 7.20) values of the liver (P < 0.05) but did not affect the content of serum lipid fractions. It is concluded that the inclusion of GLYC and lecithin in the diet did not affect liver size or serum lipid fraction. However, the inclusion of lecithin reduced the a* and b* value of the liver

O objetivo dessa tese aprofundar, a partir do discurso ps-colonial, uma crise na perspectiva teolgica da libertao. Esta promoveu, na dcada de 1970, uma reviravolta nos estudos teolgicos no terceiro mundo. Para tanto, leremos um conto de Gabriel Garca Mrquez chamado El ahogado ms hermosodel mundo (1968) analizando e avaliando as estratgias polticas e culturais ali inscritas. Para levar a frente tal avaliao preciso ampliar o escopo de uma viso que divide o mundo em secular/religioso, ou em ideias/prticas religiosas e no religiosas, para dar passo a uma viso unificada que compreende a mundanalidade, tanto do que catalogado como religioso quanto do que se pretende no religioso. A teologia/cincias da religio, como discurso cientfico sobre a economia das trocas que lidam com vises, compreenses e prticas de mundo marcadas pelo reconhecimento do mistrio que lhes inerente, possuem um papel fundamental na compreenso, explicitao, articulao e disponibilizao de tais foras culturais. A percepo de existirem elementos no conto que se relacionam com os smbolos sobre Jesus/Cristo nos ofereceu um vetor de anlise; entretanto, no nos deixamos limitar pelos grilhes disciplinares que essa simbologia implica. Ao mesmo tempo, esse vnculo, compreendido desde a relao imperial/colonial inerente aos discursos e imagens sobre Jesus-Cristo, embora sem centralizar a anlise, no poderia ficar intocado. Partimos para a construo de uma estrutura terica que explicitasse os valores, gestos, e horizontes mundanos do conto, cristolgicos e no-cristolgicos, contribuindo assim para uma desestabilizao dos quadros tradicionais a partir dos quais se concebem a teologia e as cincias da religio, a obra de Garca Mrquez como literatura, e a geografia imperial/colonial que postula o realismo ficcional de territrios como Amrica Latina. Abrimos, assim, um espao de significao que l o conto como uma no-cristologia, deslocando o aprisionamento disciplinar e classificatrio dos elementos envolvidos na anlise. O discurso crtico de Edward Said, Homi Bhabha e GayatriSpivak soma-se prtica terica de telogas crticas feministas da sia, da frica e da Amrica Latina para formular o cenrio poltico emancipatrio que denominaremos teologia crtica secular.

As a rural state, Ohio has a vital interest in addressing rural health and information needs. NetWellness is a Web-based consumer health information service that focuses on the needs of the residents of Ohio. Health sciences faculty from the state's three Carnegie Research I universitiesUniversity of Cincinnati, Case Western Reserve University, and The Ohio State Universitycreate and evaluate content and provide Ask an Expert service to all visitors. Through partnerships at the state and local levels, involving public, private, commercial, and noncommercial organizations, NetWellness has grown from a regional demonstration project in 1995 to a key statewide service. Collaboration with public libraries, complemented by alliances with kindergarten through twelfth grade agencies, makes NetWellness Ohio's essential health information resource.
