An experiment was conducted to investigate the effect of collector materials and position on Pinctada margaritifera spat attachment. Settlement on polyethylene pipes (54.6%) was significantly higher (P < 0.05) than on plastic baskets (25%). Significantly higher (P < 0.05) spat catch was recorded from the collectors which were installed on lower height of settlement tank than upper. The number o...

the structure of family organization is recognized upon members’ relationship and their rights and duties. the distinction of paternal, maternal, child and couple roles cause distinction in rights and duties. therefore the rights and duties of roles are bilateral but deferent. two characteristics explain the power division in family: biological abilities and expenditure. man in his marital role...

The effects of culture conditions and chloramphenicol treatment on the induction of the marine bacterium Pseudoalteromonas spongiae to larval settlement of Hydroides elegans were investigated. The results showed that P. spongiae cells grown in the medium containing both yeast extract and peptone (YP-grown P. spongiae) was highly inductive to larval settlement, whereas P. spongiae cells grown in...

In this paper we investigate the impact of the switching from the same-day settlement to the following-day settlement on the market volatility and its structure. Using the Levene tests and bootstrap procedures, we find that the switching causes a drastic decrease in the stock market volatility. In addition, using a modified GARCH model, we also find a substantial change in the volatility struct...

The expansion of the settlement trough is an important factor in the risk assessment of the tunneling induced settlement. The increase of settlement trough requires buildings to be included in the impact zone, which causes damages. This paper conducts estimation of the settlement trough width (STW) using empirical approaches, field measurement data and numerical solutions. The credibility of th...
