Study on Fans Cooling of Dairy Cowshed with Free Stall in Northern Mountainous Region of Hebei in Summer

The present objective of the study was to investigate the effect of fans cooling on dairy cow in northern mountainous region of Hebei in summer.Two cowsheds with the same structure and feeding technics were used to investigate the effect of fans on indoor temperature and humidity, physiological parameters and milking performance of dairy cow.The results showed that the average ambient temperature in cowshed with fans was 1.5℃ lower than that of the control cowshed, and the average wind velocity was 0.49 m/s higher than that of the control cowshed, reaching to 0.66 m/s.Temperature-humidity index (THI) of cowshed with fans was significantly lower than that of the control shed during the period of fans running (P<0.05).Besides, the rectal temperature and respiration rate of dairy cows in cowshed with fans were significantly lower than of the control cowshed (P<0.05), and the milk yield per cow per day was 17.0% higher than that of the control cowshed (P<0.05), however, the milk fat, milk protein and milk sugar were no significant difference from the control (P>0.05).Overall, fans could decrease indoor environment, moderate heat stress and increase performance and health of dairy cows in northern mountainous region of Hebei.

Respond of Stock Trading Volume to Earning Report

Earning report is a main accounting report that transmits earning information to users. It is the core of financial reports system. Earning information is significant to users' decision making. This paper studies the respond of stock trading volume to earning report and draws the curve of trading volume before and after earning report. This paper further does a regression analysis of accidental earning and abnormal return rate, and draws the relation curve of them on the earning report date to prove stock trading volume does have remarkable respond to earning report. This research is significant to either lessen small investors blindness investment and help them make reasonable forecast to markets and regulate the disclosure of listed companies.     

A FINITE ELEMENT ALGORITHM FOR PARALLEL PROCESSING OF MULTI-FRONTS

In this paper,a new algorithm for solving large-scale finite element system is presented, which utilizes the architecture of parallel processing. Firstly, the structure is partitioned into sub-regions. Then multi-fronts are used to assemble and eliminate concurrently in every sub-region. Thus the condensed interface stiffness matrices and load vectors are obtained. By serially assembling and solving global equation to get interface displacements and backing to every sub-region, the inter-nodal displacements and element stresses can be solved. The results of computation show that it can not only increase the speed of computation,but also save the memory space of computer effectively. This algorithm is an effective method for solving large-scale structural finite element systems.     

Behavior and Design of High-strength Bolt in Tensile Connection

The tensile strength of high strength bolt is affected by many factors, including prying force. The prying force can result in the increment of bolt force, for which the connection failed ahead of time. Several methods are presented for calculating the prying force. In the China's "Code for Design of Steel Structure" (GB50017), there is no formula for calculation of prying force and a factor of 0.8 is considered in formula for tensile strength of bolt for taking the prying force into account. It is proposed that the design value of tensile resistance for high strength bolt should be increased.
