Abstract: although the history of the brazilian fossil coal started in 1975, when it first was discovered, it was only after the ii world war that it began to reach the status of a modern industry. since 1970 a proper geological exploration has improved the knowledge on coal deposits. there are eight large coal fields and several minor ones in the country, most of them (88%) in the rio grande do sul state. the geometric and physicochemical parameters of the main deposits are defined and presented in this paper. the world coal reserves correspond to about four times those of its major concurrents: oil and natural gas, and they have a better geographical spread. thermoelectricity uses most of the brazilian coal; cement, petrochemical, paper and cellulose plants as well as food and ceramic industries are usual consumers. the steel manufacturing industry was an important consumer in a recent past, but nowadays it totally relies on the imported coal. brazil's balance of trade in 1996 showed a deficit of us$ 807 million and coal is the second commodity of the country's imports. more than a lack of money, the main difficulties of the coal industry were due to a technical and political misplanning that is indispensable to correct, before projecting new enterprises.

Abstract: The Galea spixii are hystricomorpha with reproductive and feeding activity subject to rainfall and climatic factors. Due to lack of knowledge on the reproductive system in Galea this study aimed to describe its macroscopic anatomy and topography. Ten adult animals from the Centre for Wild Animals Multiplication of Universidade Federal Rural do Semiarido were used. Then, dissections, photographs, and in situ organ description in order to better preserve topography. The male genitalia were represented by the testes, epididymis, accessory genital glands (represented by the prostate and the vesicular and bulbourethral glands), besides penis and scrotum. The testes were ovoid and located at different sites, depending on the animal’s reproductive activity. The epididymis had three regions: head, body, and tail. The prostate was divided into two lateral portions, with two lobes. The penis was cylindrical and it had a cranial flexure, bending it caudally. The gland was lined by a rough epithelium, keratinized with superficial spicules. The findings described for the male reproductive system of the Galea are similar to those described for rodents like the agouti and rock cavy, especially with regard to testicular gross anatomy, penis shape, and presence of spicules in the glands.

Biotemas , 2011,
Abstract: Liver lobation and intraparenchymal distribution of the portal vein was described according to studies performed in 10 specimens of Brazilian guinea pigs. The portal vein was cannulated and perfusedwith a vinyl acetate solution and the liver immersed in sulfuric acid solution to obtain vascular casts. The liver presented five lobes, which were named left lateral, left medial, square, right lateral, right medial, and caudate lobes with caudate and papillary processes. The portal vein, entering the portal fissure, divided into two branches, the right and left ones, as it entered the portal fissure. The right branch emitted isolated or common trunk branches to the right lateral lobe and to the caudate process of caudate lobe. On its turn, the left main branch of portal vein divided into two other branches. One of them formed a common trunk for the left lateral, left medial, and square lobes, being the two last ones in a common way. The second branch coursed towards to the right medial branch. Just after its formation, the common trunk of the left main branch emits small vascular branches to the papillary process of caudate lobe.

Abstract: the galea of the semi-arid northeast (galea spixii wagler, 1831) is a rodent belonging to the family caviidae. little literature is found on this species in relation to morphology, environmental and reproductive behavior. with a view to understanding the general morphology, particularly, in the innervation of the pelvic limb of this species, ponder the sciatic nerve, which is the largest of all the nerves of the body. 10 cavies were used (five males, five females) that they had died of natural causes, originating from breeders scientific, legally licensed by ibama, the ufrsa, mossoró, rn. the animals were fixed after the death in an aqueous solution of formaldehyde 10% and after 48 hours of immersion in it, were dissected to expose the sciatic nerve. thus, the data were compiled in tables and expressed in drawings and photographs. the pairs of sciatic nerves were derived from ventral roots l6l7s1 (70%) and l7s1s2 (30%) and were distributed by the deep gluteal muscles, biceps femural, semitendinosus and semimembranosus muscles.
Characterization and Potential Evaluation of Residues from the Sugarcane Industry of Rio Grande do Sul in Biorefinery Processes  [PDF]
Grazielle Machado, Fernando Santos, Douglas Faria, Taiane Nunes de Queiroz, Flávia Zinani, José Humberto de Queiroz, Fernando Gomes
Natural Resources (NR) , 2018, DOI: 10.4236/nr.2018.95011
Abstract: Brazil is the world largest producer of sugarcane (Saccharum officinarum) leading to a great generation of residues such as bagasse and straw, which represent two thirds of sugarcane energetic potential. Regarding these residues energetic potential, it is interesting to study their application in biorefinery processes. Thus, this work aimed at performing a chemical characterization of sugarcane straw and bagasse from RB867515 cultivar grown in Rio Grande do Sul-Brazil aiming at their use as feedstock in biorefinery processes. The obtained results were compared to data from other states and it was possible to conclude that edaphoclimatic conditions of Rio Grande do Sul have little influence in sugarcane residues chemical composition. Sugarcane bagasse presents larger potential for energetic use because of its volatiles content (74.82%) slightly higher than straw (68.90%), besides its high lignin content (21.85%) and higher calorific value (18.70 MJ/kg). Both sugarcane residues produced in Rio Grande do Sul have potential use as substrate in the obtainment of high value-added products from their cellulosic fractions (41.30% and 37.25%, respectively). The evaluation of energetic and chemical potential of sugarcane bagasse and straw produced in Rio Grande do Sul leads to the conclusion that these materials have high potential for use as feedstock in biorefineries.

An empiric equation for the latent heat of vaporization of moisture in bananas during its isothermal drying  [PDF]
Wilton Pereira da Silva, Cleide Maria Diniz Pereira da Silva e Silva, Fernando José de Almeida Gama, Josivanda Palmeira Gomes
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.32025
Abstract: In order to determine the energy needed to artificially dry a product, the latent heat of vaporization of moisture in the product, hfg, must be known. Generally, the expressions for hfg reported in the literature are of the form hfg = h(T)f(M), where h(T) is the latent heat of vaporization of free water, and f(M) is a function of the equilibrium moisture content, M. But expressions of this type contain a simplification because, in this case, the ratio hfg/h would only depend to the moisture content. In this article a more general expression for the latent heat of vaporization, namely hfg = g(M,T), is used to determine hfg for banana. To this end, a computer program was developed which fits automatically about 500 functions, with one or two independent variables, imbedded in its library to experimental data. The program uses nonlinear regression, and classifies the best functions according to the least reduced chi-square. A set of executed statistical tests shows that the generalized expression used in this work given by hfg = g(M,T) produces better results of hfg for bananas than other equations found in the literature.

Abstract: a brief historical review of the laparoscopy is made. the technique was introduced by kelling in 1901 and remained only exploratory during a long time and was used mainly by internists and gynecologic surgeons. nevertheless the operative laparoscopy is being used since 1970. the general surgeons have ignored its use in the treatment of digestive or abdominal surgery. the technological development with the use of computer chips and microcamera coupled to the laparoscopy made possible the first cholecystectomy by mouret in 1987. since that time, in the history of surgery, very few procedures have transformed so quickly and drastically the practice of the surgeons. the laparoscopic surgery is now effective and accurate to be employed in almost all the abdominal operations done before only by conventional way. the authors make a review of the physiological alterations occurred by the use of pneumoperitoneum during laparoscopic surgery, the limitations and the factors the can restrict the use of the technique, the present indications and the complications.
