The objective of this study was to demonstrate the environmental impacts of solid residues of Pelotas City-Brazil through photography. The research is characterized as a case study and its basis was the environmental perception through the dispositive of the look of the researchers on the environmental impact of the solid residues on the so called Fragata, Central and Porto regionals of the city. The analysis of the photographic images showed that the improper discharge of solid residues leads to environmental impacts in Pelotas and therefore causes social, environmental, economic and administrative issues. The management of the solid residues is inefficient and needs to be improved. The population must perform proper segregation, conditioning and discharging of the housing residues. The selective collection and recycling must be prioritized for the proper management of the solid residues of the city to occur. Educative environmental programs covering the different levels of the society are a necessity. Additionally, such programs are important for the proper sustainable development of the city and also to improve the quality of life of the population.
O objetivo deste trabalho foi relacionar o efeito do jejum durante a sincronização de cios com o diâmetro do folículo ovulatório e contagem de folículos antrais. Para isto foi medida a concentração sanguínea de progesterona (P4) no momento da remoção do dispositivo intravaginal liberador de progesterona (CIDR), assim como o número de folículos antrais e o diâmetro do folículo dominante de dez (n=10) ovelhas mestiças submetidas ao jejum (n=5) e alimentadas à vontade (n=5), durante 84 horas, iniciando 48 horas antes da remoção do CIDR. A contagem dos folículos e a medição do folículo dominante foram determinadas após o abate das ovelhas e coleta individual dos ovários. Não houve diferença (P>0,05) nas concentrações médias de P4 no momento da inserção do CIDR entre grupos, porém no momento da remoção do CIDR as concentrações foram diferentes no grupo jejum (4,07±0,32 ng/mL) quando comparadas com o controle (9,36±1,84 ng/mL; P0,05). Nas condições deste experimento o jejum aumentou a concentração sanguínea de P4 em ovelhas sincronizadas com CIDR, porém não teve efeito no número de folículos antrais, nem no tamanho do folículo dominante.
