Abstract: this experiment was conducted the norte fluminense state university darcy ribeiro in the aquaculture sector, aiming to evaluate the supplementation of phytase for juvenile tambaqui (colossoma macropomum). it was used a total of 170 fingerlings with average initial weight of 3.12±0.05 g and initial total length with the average of 5.36±0.06 cm. the fingerlings were randomly distributed in 20 experimental tanks with an useful volume of 40 l, being the water supplied from a closed circulation system, equipped with a biological filter. the treatments consisted of five isoproteic and isocaloric diets (28% protein and 3100 kcal ed/kg diet), supplemented with four levels of exogenous phytase (700, 1400, 2100 and 2800 uaf/kg diet) with one more without supplementation. the addition of phytase to the diets was done during the mixing of the ingredients for the manufacture of pelleted diets. it was verified the effect of phytase supplementation on the measured variables, being the smallest estimated dose equal to 1540.62 ufa kg-1 of diet for feed intake variable and the higher estimated dose equal to 2303.83 ufa kg-1 of diet for variable rate of specific development. the doses estimated in this study are much higher than those found in studies that mention the effect of supplementation on the fish, although the dose of supplementation, as well as age and other factors may be grounds, or not, for checking the action of phytase on the development of fish. at the end of the experiment, it was concluded that phytase influenced the development of tambaqui from the estimated dose, 1540.62 ufa kg-1, of diet.

Abstract: the effect of different particle size of corn ration on the performance of juvenile pacu, piaractus mesopotamicus, was evaluated. a total of 120 juveniles with an initial weight of 8.42±0.89g, total length 7.03±0.20cm, standard length, 6.32±0.13cm, and height 3.21±0.11cm, were distributed into 20 tanks (300l), at a density of six fish per experimental unit (tank), in a completely randomized design with five treatments consisting of different particle sizes 850, 710, 500, 300, 150μm of corn in the ration composition. each treatment had four replicates. among all treatments, the best animal performance was achieved with the ration with corn particle size of 150μm, reaching a feed conversion ratio of 1.38, whereas for larger feed grain size, it was 1.61. thus, the particle size of 150μm is recommended.

Journal of Fisheries International , 2012, DOI: 10.3923/jfish.2011.13.17
Abstract: Fish species abundance and distribution in the middle and lower Orange river basin were investigated in November 2010. Fish specimens were collected by means of an electric shocker and seine nets. Sixteen fish species comprising of a total number of 13,762 individuals belonging to five families were collected. The number of individuals caught showed that 64.7% were represented by the family Cyprinidae, 34.1% Cichlidae, 0.25% Claridae, 0.67% Austroglanidae and 0.36% Poecilidae. Aliens Cyprinus carpio, Gambusia affinis and translocated Oreochromis mossambicus were also recorded during the study. Labeo capensis, Labeobarbus aeneus and Pseudocrilabrus philander were the most abundant in the middle section of the river while Mesobola brevianalis and Barbus hospes were more abundant in the lower section of the river. During this study, a new distribution of Gambusa affinis was recorded at all sites except at site one and seven. High abundance of Austroglanis sclateri was only recorded at site three.

Abstract: Questions of restructuring and adjustment of religious buildings by cinemas, libraries and clubs are reviewed in the 1925-1930 years. For the first time reconstruction projects, made architects and engineers of Stalingrad, are published. Relating to spatial planning and design feature of buildings clubs and cinemas of pre-war Stalingrad are indicated. / Рассмотрены вопросы переустройства и приспособления в 1925-1930 гг. культовых зданий под кинотеатры, библиотеки и клубы. Впервые публикуются проекты переустройства, выполненные Сталинградскими архитекторами и инженерами. Приводятся объемно-планировочные и конструктивные особенности зданий клубов и кинотеатров довоенного Сталинграда.
Upgradation of Low-Grade Siliceous Manganese Ore from Bonai-Keonjhar Belt, Orissa, India  [PDF]

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.81005
Abstract: The low-grade siliceous manganese ores from Bonai-Keonjhar belt, Orissa, India was mineralogically characterized and investigated for their possible upgradation. Different physical beneficiation techniques like gravity, magnetic separation etc. were employed and results reported. The results reveal that a feed having 26% Mn could be upgraded to more than 45% Mn by using a dry belt type magnetic separator with 69% recovery at 1.00 tesla magnetic intensity at finer sizes.

Abstract: the effects of carnitine were evaluated in diets fed to trichogaster leeri, initial weight 0.5±0.2g and individually randomized into plastic containers (1000ml), with total renewal of water every 48 hours. five isocaloric diets containing 28% crude protein and 3100 kcalof gross energy were made with the supplementation of: t1= 0 mg; t2= 300mg;t3= 600mg; t4= 900mg; and t5= 1200mg of l-carnitina/kg feed. the diets were administered three times daily ad libitum for 45 days. total and standard length, height, weight and size of the tail end, in addition to weight gain, feed conversion ratio and condition factor were evaluated. in all parameters examined the treatment of 900 mg of carnitine/kg was the most efficient on the performance for the t. leeri, and after calculating the maximum points, a concentration of 1.000mg/kg feed is suggested. there was significant difference in tail length, body height, final weight and condition factors.

Abstract: Forests play a very significant role in the global carbon cycle, having absorbed approximately one third of recent anthropogenic emissions of carbon dioxide (CO2) from the atmosphere (Streck et al. 2008). However, human activities in forests have also become an important source of carbon emissions, with deforestation contributing to about one fifth of the annual anthropogenic total. Humans contribute to CO2 emissions in two ways - through burning fossil-fuels and converting forestlands to other uses. Initially, land-use changes (deforestation) were the principle source of carbon emissions. However, starting in the 20th century, fossil-fuel emissions have increased rapidly, while emissions due to deforestation have gradually declined. Therefore, one way to address the issue of increasing carbon emissions and climate change is to maintain and increase the stock of sustainably managed forests.
Don quijote, Christelike geloof en natuurwetenskap 1
H. P.P. L?tter
Koers : Bulletin for Christian Scholarship , 1987, DOI: 10.4102/koers.v52i1- 4.910
Abstract: The story about Don Qulchote and the windmills is used in this article as an analogy to typify the debates that have taken place in history between natural science and representatives of Christian religion. The analogy is tested on debates that took place around Galileo. Darwin, Newton, Cuvier and the Big Bang theory. The analogy matches these debates quite well and this Is explained by the view that scientific claims to knowledge, and claims to knowledge based on Christian faith, belong to different categories and are thus not concurrents for the same truth. Gilbert Ryle's criticism on Descartes' mind-body dualism is used here to strengthen this argument. The article is concluded by pointing out in what ways one can engage in a meaningful debate on the nature of the relationship between science and Christian religion.
