Relação peso-comprimento e fator de condição de Cichla kelberi (Perciformes, Cichlidae) introduzidos em um lago artificial no sudeste Brasileiro

The length-weight relationship and condition factor for Cichla kelberi introduced in an artificial lake in southeastern Brazil were analyzed. By studying separately the male, female and immature individuals, different length-weight patterns were found to happen among them. The same happened when distinct seasonal variations were compared. They are related to feeding alterations and me reproductive periods. The length-weight relationship and condition factor for these fishes vary in accordance with the time of introduction, population size, the characteristics of the ecosystem, sexual maturity, as well as the intra- and interspecific interactions.

Respostas da frequência de braçada e do comprimento de braçada na e acima da intensidade correspondente à máxima fase estável de lactato sanguíneo em indivíduos com diferentes níveis de performance

The main objective of this study was to analyze the behavior of variables related to swim ability at and above maximal lactate steady state (MLSS), performed at continuous and intermittent conditions in individuals with different aerobic performance levels. Participated of this study male swimmers with ages between 20 to 25 years, specialists in events of 400 m, 800 m and 1500 m and open water swims, with at least 3 years of experience in the modality. The individuals performed a maximal 400-m swim test. After this test, they were divided into two groups, in accordance with the speed attained during 400-m swim test: G1 (higher performance) and G2 (lower performance). For the determination of continuous MLSS (MLSSc), 2 to 4 trials of 30-min were performed. For the determination of the intermittent MLSS (MLSSi) 2 to 4 trials of 30-min (12 repetitions of 2 min 30 s, with 30 s of rest) were performed, in constant speed, with the first trial performed at 102.5% MLSSc. Th technical indexes, stroke rate (FB) and stroke length (CB) were determined in all tests. The SR was calculated trough recordings using the time needed to perform five stroke cycles. The SL was calculated dividing the speed by the SR. There was no significant difference on the antropometric characteristics between groups. The speed at and above MLSSc were significantly higher at G1 (1,23±0,05 e 1,27±0,06, respectively) than G2 (1,10±0,06 e 1,13±0,06, respectively). There was significant change in SL and SR in G2. In the same way, there was significant change in SL and SR only in G2, above MLSSc. Similar to continuous condition, the speeds at and above MLSSi were significantly higher in G1 (1,27±0,05 e 1,30±0,05, respectively) do que no G2 (1,14±0,07 e 1,16±0,07, respectively). There was significant change in SL and SR only in G2. There was significant change in SR and SL in both groups above MLSSi. Thus,...(Complete abstract click electronic access below)

Estudo sobre as unidades de medidas das grandezas físicas básicas: comprimento, massa e tempo

Measurement units are used almost automatically nowadays, but few people know the origin of the units of length (meter), mass (kilogram) and time (second). And do not care to know what were anciently units of which our ancestors used, the difficulties that existed to make a set of measures. The aim of this work is to make a historical approach, through various units of measure. They are old, unusual to others that have been forgotten since the standardization of meters, and is also discussed about the metric system Englih (Once and foot), AV system (eg pound grain) that are still used in some countries like United States and England, the Troy system consisting of units of measure for precious stones and metals (eg gold and diamond) are also cited some physical concepts as reference: inertial, non-inertial; mass: gravity, relativistic, inertial

Influência do aumento do comprimento de implantes dentários

The use of implants of greater length may be more favorable for the predictability of dental implants. This statement is relevant, since the cause of failures in dental implants are more related to biomechanical complications. The aim of this study was to evaluate the influence of increase of the length around the entire body of the implant. Six models were created with the presence of only one hexagonal implant (Master Screw connection, Implant Systems, São Paulo, Brazil) of 3.75 mm x 7.0 mm (Model A), 3.75 mm x 8.5 mm (Model B ), 3.75 mm x 10.0 mm (Model C) 3.75 mm x 11.5 mm (Model D) 3.75 mm x 13.0 mm (Model E) 3.75 mm x 15.0 mm (Model F) using the method of photoelasticity. The results were visualized through a qualitative analysis of stresses (number and intensity photoelastic fringes). The model A showed a pattern of less favorable stress distribution, the oblique loading was the most detrimental to the related structures. Conclusion: The increased length allowed for a better distribution of stresses. The oblique loading was more detrimental when compared to axial loading.

Comprimento radicular e nutrição de cultivares de painço em resposta à calagem

Information on improved cultivars of fall panicum and cultural practices concerning its cultivation is scarce in Brazil. So, the objectives of this research work were to evaluate root length and the mineral nutrition of fall panicum plants as influenced by liming in an acidic soil. The experiment was conducted in vases containing 13 dm3 of soil under greenhouse conditions up to 44 days after seedling emergence. The experimental units were distributed inside the green house according to a completely random design in a 2 X 4 factorial scheme, that is, two fall panicum cultivars (‘AL Mogi’ and ‘AL Tibagi’) and four doses (0.0, 1.67, 2.91, and 4.15 t ha-1 ). The experimental units were replicated 4 times. ‘AL Tibagi’ plants root system showed more tolerance to soil conditions of low base saturation. That cultivar also absorbed more efficiently P, N, Ca, Mg, and K from the acidic soil. Liming brought about increments of P, N, Ca, Mg, and S absorption by the fall panicum cultivars.

Evolução morfométrica dos anexos embrionários e fetais bovinos obtidos por monta natural, com 10 a 70 dias da gestação

O período inicial da gestação de bovinos é caracterizado por grandes perdas embrionárias. Considerando a importância deste fator no âmbito da reprodução animal foram estudados os anexos embrionários e fetais bovinos fecundados por monta natural de 15-70 dias de gestação, com o objetivo de estabelecer parâmetros morfométricos da placenta na fase inicial da gestação. Com uso de um paquímetro foram realizadas mensurações do comprimento (crânio caudal), largura (latero lateral) e altura (dorso ventral) das membranas corioalantóide e amniótica. O início da formação dos cotilédones foi observado e quantificado, assim como, o peso placentário. O peso médio do saco gestacional aumentou com o evoluir da idade gestacional, entretanto, o crescimento foi acelerado a partir de 20-30 dias de gestação. O comprimento crânio caudal e dorso ventral da membrana corioalantóide e do âmnio apresentaram crescimento lento e gradual com o evoluir dos períodos gestacionais analisados. Com 30-40 dias de gestação, os primeiro cotilédones já eram visualizados e contatos com facilidade na superfície coriônica. Os períodos de crescimento coincidiram com os maiores índices de perdas gestacionais em bovinos. Os parâmetros aqui analisados poderão servir para futuras investigações dos anexos embrionários de organismos manipulados em laboratório.
