Principales patologías reproductivas en hembras bovinas de Rancho Los Ángeles, comunidad Quínama, Municipio Villa Sandino, Chontales, Enero – Julio 2014

Con el objetivo de evaluar las principales patologías reproductivas en hembras bovinas de rancho los ángeles, comunidad Quinama, municipio Villa Sandino, Chontales, durante el período Enero- Julio 2014, ubicado en el km 203 carretera al Rama, coordenadas geográficas 1327490 latitud norte y 725705 de longitud oeste, el Rancho se encuentran a una altura de 306.27 msnm, comprendida en la zona tropical, temperatura promedio anual de 25 y 28 ºC, precipitación promedio anual de 2.000 mm y humedad relativa de 70-80 %, Se realizó un estudio de manera descriptiva para lo cual se utilizó un registro interno reproductivo que posee el rancho, esto para definir las muestras o animales que se estudiaron , el diagnóstico de las patologías se hizo por medio anamnesis, palpación rectal y examen vaginal, visitando el rancho 1 vez a la semana, siguiendo de cerca las actividades reproductiva del rancho, para identificar si hay o no patologías reproductivas, Los datos se sometieron a análisis no paramétricos para definir el grado de ocurrencia de los mismos, dentro de dichos análisis se realizaron primeramente análisis de correlación y regresión, posteriormente se sometieron a pruebas de Xi2, para determinar la normalidad y el grado de ocurrencia y si están dentro de los parámetros aceptables. Obteniendo los siguientes resultados: De las muestras total de las 20 vacas, según la ecuación general, la prevalencia de patologías reproductivas fue de un 90%, restando un 10% de animales libres de alteraciones. Las causas más frecuentes de patologías reproductivas identificadas fueron con un 44% la atrofia ovárica (AO) siendo la patología mayormente diagnosticada dentro de la muestra estudiada de casos enfermos, seguido por atrofia ovárica acompañado de vulvovaginitis (AOV) con un 27%; hipoplasia ovárica e hipoplasia ovárica acompañado de vulvovaginitis con 11%; finalmente, quistes ováricos con 5%. Y otro resultado de importancia para el estudio es la pérdida económica por las diferentes patologías reproductivas, Podemos decir que si una vaca no concibe durante todo el año por alguna patología reproductiva, el dueño del rancho estaría desaprovechando, por cada vaca un aproximado de C$ 5,989.2 de manutención y perdiendo un ingreso anual de C$24,795.8 por vaca.

Disciplinamento do processo e julgamento do mandado de injunção : uma análise sistemática

Analisa o Projeto de Lei nº 6.002/1990 e apensos, que pretendem disciplinar o processo e julgamento do mandado de injunção individual e coletivo. A abordagem e o desenvolvimento da pesquisa serão realizados no contexto da judicialização da política ou do ativismo judicial, questionando-se qual será a efetividade dos limites/parâmetros impostos ao Supremo Tribunal Federal, acaso o Projeto de Lei nº 6.002/1990 e apensos, se transformem em norma jurídica. Tem-se como hipótese compreender se o pretenso disciplinamento limitará o ativismo judicial que retira o protagonismo do Poder Legislativo e o seu papel preponderante de poder legiferante. Os objetivos específicos da pesquisa são examinar a extensão e os efeitos das decisões do Supremo Tribunal Federal no julgamento de alguns mandados de injunção; avaliar se a conduta omissiva do Poder Legislativo causa prejuízos à sua própria imagem e se essa omissão inviabiliza o exercício de direitos, liberdades e prerrogativas constitucionais. A metodologia do trabalho será balizada na análise sistemática dos Mandados de Injunção números 107/1989-DF, 631/2000-MS, 670/2002-ES, 708/2004-DF, 712/2004-PA, 721/2005- DF, 758/2007-DF, 786/2007-DF e 795/2007-DF; na análise do Projeto de Lei nº 6.002/1990 e apensos; na Constituição Federal. O trabalho terá como principais referenciais teóricos e conceituais fontes e bibliografia apropriadas, a exemplo dos doutrinadores Alexandre de Moraes, Cândido Rangel Dinamarco, José Afonso da Silva, José Joaquim Gomes Canotilho,Luís Roberto Barroso e Manoel Gonçalves Ferreira Filho.

气泡初始尺寸对泡-弹状流型转换的影响

本文对气液两相泡状流向弹状流转换的机制进行了分析,认为气泡合并是影响该流型转换的主要机制,并据此用随机数值模拟方法,对气泡初始尺寸对泡状流向弹状流转换的影响进行了研究.计算结果表明,无量纲气泡碰撞率是一条通用曲线,根据该曲线可以确定气泡初始尺寸产生影响的区域及其大小,与实验结果的比较令人满意.

The impact of varying nutrient regimes in earthen freshwater ponds on the comparative ecology of diurnally occurring candidate live feeds

The daytime composition and relative abundance of zooplankton species were studied in three treatments of two replicate earthen ponds each with nutrient sources and water replenishment regimes. Treatment -A (200m super(2) surface area supplied 900kgha super(-1) pig manure only). Treatment -B (200m super(2) surface area supplied 70kgha super(-1) month super(-1) pig manure, 50kgha super(-1) month super(-1) N.P.K. [15:15:15] and 30kgha super(-1) month super(-1) Urea) and Treatment-C (1500m2 surface area supplied 1150kgha super(-1) month super(-1) commercial grade 40% crude protein compounded feed). Water replenishment for Treatment A was daily tidal deluge from the New Calabar River while that for treatment B and C was from column-well and occasional rains. No zooplankton species were recovered from the pig-manure only treatment (A) while only Diffugia constricta and Difflugia urceolata were the two protozoans that occurred together in treatments B (combined fertilization) and C (compounded feed only) in contrast, Difflugia acuminate and three rotifers, Collurella uncinata, Diurella stylata and Keratella quadrata occurred only treatment B. similarly, Arcella arenaria, Arcella costata, Centropyxis aculeate, Difflugia pyriformis, Branchionus calyciflorus, Lepadella patella, Polyarthra trigla and Onchocanmptus mohammedi were recovered from treatment C. Arcella costata was the most abundant zooplankton in the entire experiment, while Arcella arenaria was very abundant in treatment C, Collurella uncinata was very abundant in treatment B. The inference is that combined fertilization of earthen freshwater ponds tend to be more suitable for the culture of rotifers such as Brachionus calyciflorus, popular in fish larva nursery, while those supplied compounded feed could be used to produce protozoans where desirable

Absorption characteristic and nonvolatile holographic recording in LiNbO3 : Cr : Cu crystals

The absorption characteristic of lithium niobate crystals doped with chromium and copper (Cr and Cu) is investigated. We find that there are two apparent absorption bands for LiNbO3:Cr:Cu crystal doped with 0.14 wt.% Cr2O3 and 0.011 wt.% CuO; one is around 480 nm, and the other is around 660 nm. With a decrease in the doping composition of Cr and an increase in the doping composition of Cu, no apparent absorption band in the shorter wavelength range exists. The higher the doping level of Cr, the larger the absorbance around 660 nm. Although a 633 nm red light is located in the absorption band around 660 nm, the absorption at 633 nm does not help the photorefractive process; i.e., unlike other doubly doped crystals, for example, LiNbO3:Fe:Mn crystal, a nonvolatile holographic recording can be realized by a 633 nm red light as the recording light and a 390 nm UV light as the sensitizing light. For LiNbO3:Cr:Cu crystals, by changing the recording light from a 633 nm red light to a 514 nm green light, sensitizing with a 390 nm UV light and a 488 nm blue light, respectively, a nonvolatile holographic recording can be realized. Doping the appropriate Cr (for example, N-Cr = 2.795 X 10(25)m(-3) and N-Cr/N-Cu = 1) benefits the improvement of holographic recording properties. (c) 2005 Optical Society of America.

Elasmobranch Landings for the Portuguese Commercial Fishery From 1986 to 2001

Portuguese commercial elasmobranch landings were analyzed for the period 1986–2001. An average of 5,169 (± 795 t) were landed yearly, representing 18 families, 29 genera, and 34 confirmed species. However, annual landings for the fishery generally decreased over time, with a corresponding increase in price per kilogram. The most important group, Raja spp., accounted for 33% of the landings or 26,916 t. They were followed by Centroscymnus coelolepis, Scyliorhinus spp., Centrophorus granulosus, and Centrophorus squamosus (accounting for 12%, 12%, 11%, and 9% of the landings, respectively). In the absence of CPUE data, the comparative trends of landings and price were employed as an indicator of the “status” of specific elasmobranch species. Raja spp., Centrophorus granulosus, Mustelus spp., Torpedo spp., and Squatinidae displayed indications of possible overexploitation, and they merit the focus of future research.
