一根“龙杆”百年传

一根近7米长、200公斤的“龙杆”被十几名大汉抬出立起,登杆者腰系绳索、爬上竹竿,站在仅碗口大小的竹竿顶部,表演倒香炉、转幺幺、蹬鸭、耍流星等高难度动作……引得四周的观众不时发出惊呼。

秩序与机制:一个西南农村民间组织对乡村社会关系修复的案例

近年来,在传统丧葬文化保持得较为完好的贵州农村地区,葬礼操办存在一种从宗亲互助向地区性邻里互助转变的趋势。贵州省石桥村建立专门的丧葬互助组织“龙杆会”,通过应急策略、集体制裁、互惠原则等规约机制,以及场景安慰、主家信任、集体依赖等情感机制,以“村民小组-社区-村庄”的互助逻辑调整着乡村社会关系。该组织在促进乡村劳动力回流、加强人情往来以及加固村落团结等方面都发挥着重要作用。可为在农村空心化程度不断加剧的今天,就修复村庄共同体关系问题提供一个有益的实践案例。

Continuous Lactic Acid Production from Longan Juice by Lactobacillus casei subsp, rhamnosus TISTR 108

This research focused using novel substrate, longan Lactobacillus casei subsp, rhamnosus TISTR 108. The optimum juice as carbon source for continuous lactic acid production by medium for lactic acid production was pure longan juice with 120 g/L sugar concentration and among the different nitrogen sources were added to the longan juice （yeast extract, tryptic soy, urea, （NH4）2SO4 and NaNO3）, yeast extract had the most efficiency. Yeast extract （10 g/L） without adding minerals to longan juice could produced the maximum lactic acid concentration of 38.91 ± 0.190 g/L in 60 h and the yield of 0.460± 0.122 g/g with the productivity of 0.649± 0.002 g/Lh in 2 liters flask. Batch fermentation was conducted in 2 liters fermentor and 41.38± 0.030 g/L lactic acid was produced in 48 h with the yield of 0.398 ± 0.215 g/g and the productivity was 0.862 ± 0.001 g/L h. The continuous fermentation using 2 liters fermentor as a high productivity for lactic acid （1.091 ± 0.001 g/L h） was achieved at dilution rate （D） of 0.0685 h-1.

临江粉干

我经常挂在嘴边的一句话——我是农民的儿子,严格说来这句话不对,我只能算一个小手工业者的儿子,不怕大家笑话,我的父亲是加工粉干的。改革开放前,浦城临江粉干以铁炉、樟山两生产大队手工作坊加工的最著名,改革开放后,樟山的＂粉二代＂们都考上大中专学校当干部去了,加工粉干从此在樟山失传了，临江粉于就演变成铁炉粉干。
