The samples were collected from different segments of production lines from reception to packaging sections, over a period of 75 days at a rate of one sampling a week, from plants in North West of Algeria. The total colony count of aerobic spore-forming bacteria was done using Plate Count Agar （PCA） method. The results showed that there was more than 1 ×10^3 CFU/mL at the level of 50%, 25%, 37.5%, 62.5% and 37.5% of the analyzed samples of milk powder, pasteurized milk, UHT milk （before storage）, UHT milk stored at 55℃ for 7 days and UHT milk stored at 30℃ for 14 days, respectively. The mean total colony count of aerobic spore-forming bacteria was considerably lower in the UHT milk than in the other samples, while the higher proportion of aerobic spore-forming bacteria was noticed to be 32.58% and 30.90% in the UHT milk stored at 55℃ and 30℃, respectively. The results obtained by the classic biochemical identification （Bacillus API 20E）, interpreted by software of calculation for microbial identification reflected the presence of especially Bacillus sphaericus. The other species found were： Bacillus cereus, Bacillus subtilis, Bacillus coagulans, Bacillus licheniformis and Bacillus stearothermophilus. The study reveals that the proportion of aerobic spore-forming bacteria in the final product depends on temperature and storage periods.展开更多

Due to globalization and changes in the world, housing is no longer only a structure that provides sheltering but is also a factor that provides mutual interaction in formation of life style and quality. The elements such as the increase in the effect of consumption preferences and life style on selections, the changes in family structure, and urban structures also influence the residences used and housing preferences. The purpose of this study is to determine the general situation of housing preferences while taking into account the family life style in Turkey and at the same time to make an evaluation based on international publications.展开更多

The aims of the study were to explore factors affecting farmers’ implementation of WFF practices on Sado Island, Japan and to consider the policy implications of disseminating such practices. All 5010 farming households on Sado Island, who are distributing rice to Japan Agricultural Cooperatives （JA）, were surveyed. In total, 2231 households responded to the questionnaire （response 44.5%）. By comparing the attitudes, beliefs, and attributes of non-certiifed versus certiifed farmers, we identiifed key factors affecting farmers’ implementation of WFF practices. Compared with non-certified farmers, certified farmers： （i） showed a greater interest in biodiversity and the ifnancial beneifts of WFF; （i） had a larger number of certiifed farmer friends; （ii） felt many more pressures and expectations from consumers, in particular; and （iv） were not hampered by bad labor or farmland conditions when implementing WFF practices. To further disseminate WFF practices in Sado, we suggest that the information on the effectiveness of WFF on paddy ifeld biodiversity is used in public education, and opportunities for interchanging opinions are set up between non-certiifed and certiifed farmers, as wel as between farmers and consumers.展开更多
