  damage loss
However, severe capillary damage (loss of capillaries) was noticed more frequently in patients with dcSSc (dcSSc/lcSSc: 85.5%/48.0%, p=0.002).
      
The key parts of this information system are the subsystem for rapid evaluation of damage loss from earthquake and the subsystem for the decisive information on earthquake emergence.
      
We can approximate an upper limit for the damage loss rate up to which the flow's send rate is insensitive.
      
The total damage loss is about $5.5 billion, in addition to a daily production loss of $111 million.
      
The rate at which packet transmission errors occur for a given flow is called the damage loss rate.

The black chafer Holotrichia morosa Waterhouse is a dominant spe- cies among the peanut white grubs complex in the Yellow River and Huai River Basins.It has one generation each year and the winter is passed as high instar larvae and a few adults.This white grub has a food preference for peanuts,the second and third instar larvae being more injurious.Experiments on its damage loss relations showed that losses in peanuts yield are closely correlated to the number of grubs per square meter.The regression...

The black chafer Holotrichia morosa Waterhouse is a dominant spe- cies among the peanut white grubs complex in the Yellow River and Huai River Basins.It has one generation each year and the winter is passed as high instar larvae and a few adults.This white grub has a food preference for peanuts,the second and third instar larvae being more injurious.Experiments on its damage loss relations showed that losses in peanuts yield are closely correlated to the number of grubs per square meter.The regression equation is:y=441.38-6.32x(r=-0.977~(**)).It is considered that the economic injury level of the peanut white grub should be kept between 2% and 3%. The last peak of egg hatching is the critical moment for the chemi- cal control of this grub.Broadcasting along the rows of peanut plants with 50% phoxim at the rate of 0.25kg mixed with 30kg of soil per mu gave good control.This should be done when the number of white grubs are found less that 3 per square meter.For pouring of the same insec- ticide diluted with water onto the peanut hills,the economic threshold should be below 4 larvae of this grub per square meter.

花生受蛴螬为害已成为花生生产上的严重减产因素。暗黑鳃金龟(Holot-richia morosa Waterhouse)在黄淮海地区是优势种之一。一年一代,主要以老熟幼虫过冬。幼虫(蛴螬)嗜食花生荚果。花生亩产与每平方米的蛴螬数量呈负相关,其回归方程为 y=441.38-6.32x(r=0.977~(**)),损失率为1.43%。通过研究认为,花生蛴螬为害花生的经济允许受害水平以2~3%为宜。每亩用50%辛硫磷乳利0.5斤撒毒土防治一次蛴螬时,其经济阈值为每平方米有蛴螬2.58头;如以同样剂量的药液浇毒水时,其经济阈值为每平方米有蛴螬3.65头。

The paper introduced two methods of earthquake damage loss evaluation, that is total probability method and unit area method, and made evaluation to Ningxia and Qinghai provinces.

The classification, damage loss and control strategy were studied for cotton boll rots in Shanxi province. Results showed that the main kinds of cotton boll rots included boll blight (Phytophthora boehmriae), rose rot (Fusarium moniliforme) and pink rot (Cephalothecium roseum), and boll blight was the dominant species. Comparison revealed that boll rot in the film-mulched field was more severe than that in the open field. The results of Bayes decision analysis indicated that 67.4-89.1% of the secondarily-affected...

The classification, damage loss and control strategy were studied for cotton boll rots in Shanxi province. Results showed that the main kinds of cotton boll rots included boll blight (Phytophthora boehmriae), rose rot (Fusarium moniliforme) and pink rot (Cephalothecium roseum), and boll blight was the dominant species. Comparison revealed that boll rot in the film-mulched field was more severe than that in the open field. The results of Bayes decision analysis indicated that 67.4-89.1% of the secondarily-affected boll population originated from the prima'rily-affected bolls, especially those affected by boll blight. Significace tests indicated the vertical distribution of the affected bolls on the branches consisted of 2 strata, i.e. the first to the fourth boll-branch stratum and the 5th to the 7th boll-branch stratum for the film-mulched field, and the first to the second boll-branch stratum and the 3rd to the 6th boll-branch stratum for the open field. The quantitative relationship between the primary and the secondary pathogenetic fungi infections was clarified, and the main objects and target areas were defined for boll rot control. These results provided a theoretical basis for the integrated control of cotton boll rots.

山西省棉花铃病的主要种类为疫病(Phytophthora boehmriae)、红腐病(Fusarium moniliforme)和红粉病(Cephalothecium roceum),其中以棉铃疫病为优势种,在不同栽培方式中地膜田铃病重于露地。Bayes决策分析结果,次生病烂铃群体中67.4~89.1%的病铃来源于初生病铃,尤其是疫病铃。根据显著性检验结果,烂铃在棉株不同果枝上的垂直分布,地膜田可划分为第1~4和第5~7果枝两个层次;露地田可分为第1~2和第3~6果枝两个层次。该项研究明确了初生病菌与次生病菌侵染之间的数量关系及防治上的主要对象和靶区,为铃病的综合防治提供了理论依据。
