Influência do estádio de lactação, hora e número de ordenhas sobre o teor de cloretos no leite caprino

De outubro de 1998 a fevereiro de 1999 foram analisadas 359 amostras de leite colhidas de 28 cabras lactantes, nos estádios inicial, médio e final da lactação, nas ordenhas da manhã e da tarde. de março a julho de 1999 foram analisadas 150 amostras de leite dos mesmos animais, ordenhados uma única vez ao dia. Os teores de cloretos de amostras colhidas nos períodos da manhã e da tarde apresentaram valores crescentes (P<0,01) durante a lactação, 0,175gCl/100ml e 0,211gCl/100ml de leite nos estádios inicial e médio, respectivamente, para as amostras colhidas nas ordenhas da manhã e 0,183gCl/100ml e 0,217gCl/100ml de leite nos estádios inicial e médio, respectivamente, para as amostras colhidas nas ordenhas da tarde. Para as amostras de leite colhidas de animais ordenhados uma única vez observou-se aumento no teor de cloretos (P<0,01) do início para o final da lactação, 0,179gCl/100ml e 0,216gCl/100ml de leite, respectivamente. em relação ao horário e número de ordenhas, as diferenças não foram significativas. Os resultados ressaltam a necessidade de se estabelecer padrões físico-químicos específicos para o leite de cabras, uma vez que, independente do estádio da lactação e do número de ordenhas diárias, os valores estão acima dos limites considerados normais para o leite bovino.

A Hora e o Nevoeiro: discurso épico, vontade de potência e mal-estar da modernidade no poema Mensagem de Fernando Pessoa

Considering articles written for Fernando Pessoa in 1912 about The new Portuguese poetry , where he already proclaimed the appearance of the Super-Camões, poet that would be able to revolutionize Portuguese literature e, concomitantly, to make resurging from rubble the Portuguese nation; we understand that, decades before the writing of Message, the poet was already armed with a Will of Power , expression of Friedrich Nietzsche that incorporate the idea of resurgence to the man like creator of news values. Fernando Pessoa believed to make his poetical word, the epic, restoring word of the ideas of Messianism and Fifth Empire as the pushing force of the new Portuguese largeness. However, we look for to investigate the conditions of Malaise that surround the universe of the poem and that restrict its capacity of action on the reality in its return, a time that the space destined in modernity to the poet and to his poetry hindered him of a devoted and positive action, We select therefore theorist like Sigmund Freud e Walter Benjamin

Influência da idade, do sexo e da hora do dia no desempenho em teste de labirinto

The increase of elderly population in the world and in Brazil has indicated the necessity of health systems capable to evaluate, to diagnose and to intervene in the conditions of health and disease of that segment. During that stage of human development, physical and cognitive changes happen and they are capable to influence the functional acting. It s important to distinguish the limit between the normal and the pathological. Besides the common changes during the aging, biological rhithmicity changes happen, as alterations in the cycle vigil-sleep that can influence in certain tasks performance. This study aimed to verify the influence of the age, of the sex and of the hour in a maze test performance. Eighty individuals were evaluated, 40 youths (20 men and 20 women) and 40 senior (20 men and 20 women). They were separated in 2 different groups that were tested at 9:00 o clock and at 15:00 o clock. Initially they were submitted to health evaluation, cognitive evaluation and of sleep quality and chronotype. They were instructed to accomplish the maze test whose time of execution was timed and registered. Significant differences were observed according to age for the masculine group between elderly in the morning and in the afternoon and in the feminine group between youth and elderly in the test accomplished in the morning and in the afternoon. Significant differences were not observed according to sex and hour of the day and also between attempts. In compare between the 30th and the31st, accomplished in a 15minutes of interval, significant difference was observed just for the elderly group in the morning and in the afternoon. We observed significant correlations in the maze test performance with the cronotype, with the age, with the education and with the cognitive acting. The maze test was capable to detect differences between age in the acting profile and in the evaluation of the information maintenance after 15 minutes, however it was not possible to verify difference between sex and hour of the day. Finally the correlations of the maze test with another varied may indicate your importance as coadjutant instrument in those functions evaluation

Influência da estação do ano, estádio de lactação e da hora da ordenha sobre o número de células somáticas do leite bovino

From January to October of 1995, somatic cell countings were accomplished in 2,218 milk samples collected from 67 quarters of 17 lactating cows at the initial, middle and final stages of lactation, in the morning and evening milkings. The highest means of cell countings were observed among the milk samples collected at the Final stage of lactation 15.652cell/ml), in the winter (5.358cell/ml) and the afternoon milking (5.199cell/ml). The differences observed amongst the cell countings in samples obtained at the different stages of lactation and the morning and afternoon milkings were statistically significant (P < 0.0001). In contrast differences observed amongst the seasons of the year, showed to be non-significant at the level of 5% probability. Higher occurrence of samples with cell countings superior to 500,000cell/ml was verified at the final stage of lactation (34.9%), in the winter (23.6%) and the afternoon milking (21.3%). These findings show the influence of physiologic and management factors (stage of Lactation and milking time) on milk cell concentrations.
