Since 1996, the Turopolje pig is recognised as a Croatian autochthonous extensive pig breed and was include in program of "in situ" preservation. The purpose of this paper was to analyze the changes in breeding population of Turopolje pig in relation to re productive traits and brucellosis outbreaks. 529 liters from 388 sows were analysed in the period from 2000 to 2 009. In average 1.2 liters/sow/year were observed with 4.21 and 3.90 piglets born alive and weaned per litter, respectively. Mortality rate during the weaning period was close to 20%. In the period from 1996 to 2009 the size of breeding population was increased more than ten times in the number of sows and five times in the number of boars. In 2008, the numbers of sows and boars decreased about 21% in relation to 2 007, primarily due to an outbreak of brucellosis. In average 44.2% and 30.1% of tested pigs during 2008 and 2009 were serologically positive to Brucella suis infection and were excluded from population. These results suggest requirements to increase the number of litters per year and survival of pigs born alive due to changes in Turopolje pig production system and development of a health monitoring program.

Na uzorku od dvadeset i cetiri (N=24) studenta prve godine Fakulteta fizickog vaspitanja i sporta Univerziteta u Banjoj Luci, sprovedeno je transferzalno istraživanje s ciljem da se istraži povezanost mase tijela, kao reprezenta tjelesnih dimenzija, sa ispoljavanjem maksimalne sile muskulature nogu. U ovom istraživanju eksperimentalni pristup u određivanju alometrijskog eksponenta, za testove kojima se procjenjuje maksimalna sila muskulature nogu (Cucanj 80° b=0.78, cucanj 110° b=0.88, cucanj 140° b=1.06, cucanj 1RM b=0,62), obezbjeđuje rezultate približne teorijski predviđenim. b=0.67 ukoliko se rezultati testova normalizuju masom tijela (m). Tako da ispoljavanje maksimalne sile muskulature nogu zavisi od tjelesnih dimenzija, prije svega od tjelesne mase, i da bi se dobila relativna sila (jacina) ispitanika rezultate mjerenja maksimalne sile muskulature nogu treba dijeliti sa masom tijela stepenovanom alometrijskim eksponentom.

In Hadzimehmedovicet al.[Phys. Rev. C 84, 035204 (2011)] we have used the Zagreb realization of Carnegie-Melon-Berkeley coupled-channel, unitary model as a tool for extracting pole positions from the world collection of partial-wave data, with the aim of eliminating model dependence in pole-search procedures. In order that the method is sensible, we in this paper discuss the stability of the method with respect to the strong variation of different model ingredients. We show that the Zagreb CMB procedure is very stable with strong variation of the model assumptions and that it can reliably predict the pole positions of the fitted partial-wave amplitudes.

Este trabalho foi desenvolvido no viveiro de producao de mudas no Instituto Federal de Educacao, Ciencia e Tecnologia do Rio Grande do Norte – Campus Ipanguacu (IFRN/Campus Ipanguacu) com o objetivo de analisar o desempenho do microaspersor Amanco MF (bocal branco de 1,14 mm) em condicao de campo. O coeficiente de variacao de fabricacao (CVf) foi de 2,29%, que, de acordo com a ABNT, e considerado bom. A equacao caracteristica Q = 5,7655P0,7179, foi ajustada atraves de regressao linear, com um coeficiente de determinacao (R2) de 0,9993. As vazoes medias do microaspersor ficaram 25 % abaixo das apresentadas no catalogo do fabricante, no intervalo de pressao de 100 a 250 kPa. O emissor apresentou intensidade de precipitacao media de 0,0031 mm h-1 na superficie estudada. O perfil de distribuicao tridimensional e as isoietas de precipitacao apresentaram-se bastantes irregulares. PALAVRAS-CHAVE: perfil tridimensional de aplicacao, microaspersao, intensidade de precipitacao,equacao caracteristica, coeficiente de variacao de fabricacao.
