On the basis of the viewpoint of preparation of strong earthquakes in group, the spatial andtemporal scanning characteristics of the seismicity in the South Yellow Sea and its coast regionare studied, and some problems regarding the prediction of seismic hazard are also *** results show that the seismic activity of M=4. 0 earthquakes has overall presented arelative stable state, but the partially concentrated area wbich evolves and migrates and theanomalous low b-value area have appeared in different periods, and the moderately strongearthquakes with M=5. 0～6. 0 have taken place on the edge of the anomalous area. Theaccumulative frequency of M=4. 0 earthquakes in the anomalous area presents non-linearindex acceleration and the moderately strong earthquakes have appeared in the late period ofthe non-linear index acceleration of M=4. 0 earthquakes or in the later anomalous tranquilperiotl.

A new capacitance probe is developed for measuring local moisture content in wet porous media. The measurement principle, sensor structure of the probe, dynamic response characteristics and calibration procedure are discussed in detail. The experimental results show that the probe can be used to measure the local moisture content in wet porous media.

＜正＞The increased usage and proliferation of small scale digital devices,like phones.A smart phone is a handheld device that combine the functionality of a cell phone,a personal digital assistant（PDA） and other information appliances such a music *** devices can however be used in a crime and would have to be quickly analysed for evidence. This data is collected using either a forensic tool which resides on a PC or specialised *** paper proposes the use of an on - cell forensic tool to collect the contents of the device and store it on removable *** Approach requires less equipment and can retrieve the volatile information that resides on the phone such as running processes.

This paper deals with the singular nonlinear third-order periodic boundary value problem u'' + p(3)u = f (t, u), 0 less than or equal to t less than or equal to 2pi, with u((i)) (0) = u((i)) (2pi), i = 0, 1, 2, where p is an element of (Graphics) and f is singular at t = 0, t = 1 and u = 0. Under suitable weaker conditions than those of [1], it is proved by constructing a special cone in C[0, 2pi] and employing the fixed point index theory that the problem has at least one or at least two positive solutions.

OBJECTIVE: To observe the effect of tail vein injection with donor hepatocyte and/or splenocyte on islets xenotransplantation rejection. METHODS: New-born male pigs and BALB/C mice were selected as donors and recipients respectively. Islets xenotransplantation was performed in recipients just after the third time of tail vein injection with donor hepatocytes and/or splenocytes. Macrophage phagocytosis, NK killing activity, T lymphocyte transforming function of spleen cells, antibody forming function of B lymphocytes, and T lymphocyte subsets were taken to monitor transplantation rejection. The effects of this kind of transplantation were indicated as variation of blood glucose and survival days of recipients. RESULTS: Streptozotocin (STZ) succeeded in inducing diabetes mellitus models of mice. Pre-injection of donor hepatocytes, and splenocytes or their mixture via tail vein was effective in preventing donor islets transplantation from rejection, which was demonstrated by the mentioned immunological marks. And each group of transplantation could decrease the blood glucose of recipients and prolong the survival days. Pre-injection of mixture of donor hepatocytes and splenocytes was more effective in preventing rejection than pre-injection of donor hepatocytes or splenocytes separately. CONCLUSION: We propose that pre-injection of donor hepatocytes, splenocytes separately or their mixture before donor islets transplantation is a good way to prevent rejection.

Zinc nitride (Zn3N2) powder has been synthesized through the nitridation reaction of Zn powder with NH3 gas (at the flow rate of 500 ml/min) at the nitridation temperature of 600℃ for 120 min. X-ray diffraction (XRD) indicates that Zn3N2 is cubic in structure with the lattice constant being a = 0.9788 nm. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) show that Zn3N2 powder has surface morphology of various types. X-ray photoelectron spectroscopy (XPS) shows the differences in chemical bonding states between Zn3N2 and ZnO, and confirms the formation of N–Zn bonds. Observation through high resolution transmission electron microscopy (HRTEM) also indicates that the computer simulation of the structure of Zn3N2 is consistent with the structural model put forward by Partin.

The core of issues concerning agriculture,countryside and farmers is farmer problem,and the key to farmer problem is the problem of farmers' overall quality. Farmers' cultural quality,technical level and ideological and moral standards,directly determine the success of countryside construction and agricultural development. Therefore,many countries have attached great importance to farmers' education and training,and established the training mode with their own characteristics,playing an important role in improving the comprehensive quality of farmers,promoting the advance of social modernization,and propelling sustainable social development. By probing into the history of the development of foreign farmers' education and training,I summarize the main features,and conduct in-depth scientific analysis,which will provide a reference for developing farmers' education and training,and resolving issues concerning agriculture,countryside and farmers in China during the period of social transformation.
