云和县加大巡查力度 严肃查处土地违法案件

云和县国土资源局为进一步加大土地动态巡查力度，通过定区域、人员、时间、任务，强化了巡查制度。针对一些群众目无法纪，利用节假日突击抢占土地搞违法建筑，今年国庆期间，土地执法监察大队巡查人员放弃休息时间，每天坚持下乡巡查，在一个月时间里巡查发现非法占地案件29起，面积3132平方米。为了把土地违法行为制止在萌芽状态，巡查人员每发现一处，当即对当事人发出停工通知书，并责令恢复土地原状。     

Rhombic Cell Analysis. Ⅱ. Application to the IRAS／PSCz Catalogue

Rhombic cell analysis as outlined in the first paper of the present seriesis applied to samples of varying depths and liming luminosities of the IRAS/PSCzCatalogue. Numerical indices are introduced to summarize essential information.Because of the discrete nature of the analysis and of the space distribution of galax-ies, the indices for a given sample must be regarded as each having an irreduciblescatter. Despite the scatter, the mean indices show remarkable variations acrossthe samples. The underlying factor for the variations is shown to be the limitingluminosity rather than the sampling depth. As samples of more and more luminousgalaxies are considered over a range of some 2.5 magnitudes (a factor of some 75in space density), the morphology of the filled and empty regions defined by thegalaxies degrades steadily towards insignificance, and the degrading is faster for thefilled than the empty region.     

维护农民合法权益促进农民增加收入

Comparison of Taste Components between Triploid and Diploid Oyster

The main taste components of triploid and diploid oyster (Crassostrea gigas) were compared. Free amino acids, inosine monophosphate, succinate, trimethylamine oxide and betaine in fresh and boiled extractives were analyzed. The protein, lipids, glycogen, moisture and ash, which may affect the flavour, were evaluated. In boiled extractives, the amino acids were 394.1 mg(100g)^-1 in diploid and 183.5 mg(100g)^-1 in triploid. However, in fresh oyster extractives, they were 320.0 mg(100g)^-1 and 147.3 mg(100g)^-1 respectively. The inosine monophosphate in triploid was 44% more than that in diploid, and a little difference existed in the content of trimethylamine oxide between them. The contents of these taste components were the basis for taste flavour pattern determination.
