The importance of livestock and culture associated with them has got a greater impetus in the post-conflict political reform in Ethiopia. The 1990s reform provided opportunities for various ethnic groups to resuscitate aspects of their traditions that were suppressed under the previous regimes. The purpose of this study is to explore socio-economic and environmental roles of cultural based notion of cattle counting rite of the Wolaita People. The practices of cattle counting of Wolaita are called as Dala and Lika, which refers to ceremonies of public displaying of one’s own cattle wealth numbering minimum of, respectively, hundred and thousand cattle. The Dala and Lika ceremonies honor men. However, there is also Gimuwa ceremony which honors women. The ceremony of cattle counting is accompanied by the lavish feasts and series of rituals. The central figures in cattle counting rite are wealthy farmers who wish to achieve social prestige by demonstrating their cattle wealth. The practices have got a greater attention by the farmers of Wolaita since the fall of the socialist regime in 1991. Using ethnographic technique, this article tried to explore the practices of the Dala, Lika and Gimuwa, focusing on how the cattle counting rite gives economic and social status to the farmers and ensure environmental sustainability.展开更多

Autumn is harvest season.The city of Ningbo awarded the whole textile and apparel industry with the annually fashion feast–the Fashion Ningbo (Ningbo International Fashion Festival)from October 20th to 24th.
In golden October when all are fascinated with the great joy of celebration China's 60th birthday,we are welcoming the smooth opening of the 13th Ningbo International Fashion Festival.

Although kinetic selection based on storage response should bring about a predominance of floc-formers, a bulking sludge with storage response comparable to well-settled sludge was steadily established. An anaerobic phase was introduced before the aerobic phase in the ADF model to improve the sludge settleability （SBR #1）, however, due to the consequent increased feast/famine ratio, the performance of SBR #1, in terms of both the maximum PHB （polyhydroxybutyrate） cell content and APHB, was lower than that of SBR #2. SBR #2 gradually reached a steady state while SBR #1 failed suddenly after 50 days of operation. The maximum specific substrate uptake rate and storage rate for the selected bulking sludge were 0.4 Cmol Ae/（Cmol X.hr） and 0.18 Cmol Ac/（Cmol PHB.hr）, respectively, resulting a yield of 0.45 Cmol PHB/（Cmol Ae） in SBR #2 in the culture enrichment phase. A maximum PHB content of 53% of total suspended solids and PHB storage rate of 1.36 Cmol Ac/（Cmol PHB.hr） was achieved at 10.2 hr in batch accumulation tests under nitrogen starvation. The results indicated that it was feasible to utilize filamentous bacteria to accumulate PHA with a rate comparable to well-settled sludge, Furthermore, the lower dissolved oxygen demand of filamentous bacteria would save energy required for aeration in the culture enrichment stage.展开更多
