加入WTO对反腐败斗争的影响及对策思考

加入世贸组织总体上对我国的反腐败斗争是有利的。但由于西方国家对我国进行外部渗透和影响的机会增多;我国经济、政治等体制改革的不彻底;入世初期的接轨工作难以到位;高智化、国际化、团伙化的犯罪特点;新一轮资产重组等原因，存在着腐败滋生蔓延的必然条件，新的腐败犯罪的高发期还可能出现。为此，我们要坚持依法治国，加强法律、法规建设，加快政治体制改革，强化办案职能，严肃查处各种腐败犯罪，加大对国有资产监管的力度，依法治权，依法行政，完善党内各项运行机制，从源头上预防和治理腐败;加强思想教育，提高党员干部素质，增强拒腐防变的能力，自觉抑制腐败;密切国际间的相互协调与合作，共同打击腐败。

Study on Site-specific Nutrient Management in Cotton Field

The study on the characteristics of spatial variability of soil nutrients and fertilizer recommendations in cotton field under certain conditions of agricultural management was conducted with GIS and systematic approach for soil nutrient constrains. The results showed that of the spatial variability of soil nutrient was greatly related to the management condition of previous crops. Grid sampling and variable rate application technology (VRAT) were the tools that would hopefully increase fertilizer efficiency. The fertilizers were applied where they were needed and at proper rate. Balance fertilization demonstration showed that fertilizer recommendations according to the available nutrient level in soil could decrease fertilizer cost with 657.4 yuan / ha and increase seed cotton yield by 19.8%. A net profit of the balanced fertilization was 5314.9 yuan / ha higher than that of local fertilization practice.     

输气管道水化物堵塞的预防和处理

阐述了输气管道内水化物的成因，特性及游离水的来源，并对其进行了分析，根据分析结果，给出了预测管道内水化物形成区域的方法，提出了三项预防水化物的措施，（1）施工阶段避免过多使用弯管，（2）投产前增加吹扫次数，彻底清除水，（3）运行初期定期注入抑制剂，指出对已形成水化物的管道段，可采取尽快降低运行压力，加热，注醇和放空等措施进行处理。

The Effect of Detopping the Field Bean Plants (Vicia faba L. minor) and Lack of the Pod Setting on the Symbiosis with Root Nodule Bacteria

The plants of field bean var. Nadwiślaνski were detopped after about 1 month since the beginning of flowering and after that all flower buds were removed from some plants. The effect of a change in the trophic balance on the setting and subsequent growth of root nodules was studied.
The removal of pods had the greater effect on the increase in the weight of the remaining organs than the detopping of plants. Detopping retarded the ageing of the plants and delayed the phase of the greatest reduction of the number of pods. The detopping of plants revealed their considerable compensative possibilities in terms of production of the pod weight and the potential of leaves for biomass production. The data obtained indicate that plant detopping may disturb the root–bacteria exchange of signals, necessary to initiate the nodule development, while the further growth of nodules depends, above all, on the amount of available photosynthates.
A very high correlation between the dry weight of the whole plant to the dry weight of leaves ratio and the weight of nodules was observed. It proves the importance of the trophic balance of the plant for the root nodule weight production.     

Feline Ubiquitin Fusion Protein Genes

Using cDNA from a CRFK cell line as a template, PCR amplification was performed with the Ub1S and poly(dT) primers to isolate feline ubiquitin genes. Sequencing of the 495 bp PCR fragment revealed that the putative amino acids induced by this fragment gave a fusion protein consisting of a ubiquitin polypeptide (76 amino acids) and an extension protein of ribosomal proteins L40 (52 amino acids). The putative amino acid sequence of ubiquitin was identical to those of humans, rats and pigs.The recombinant glutathione S-transferase (GST)–feline ubiquitin fusion proteins were produced in Escherichia coli and purified. The fusion proteins had a molecular weight of about 42 kDa and were detected by immunoblot assay with rabbit anti-ubiquitin antiserum.The mRNAs from heat-shocked and non-heat-shocked cells were subjected to RT-PCR (Ub1S and poly(dT) primers) analysis. The molecular weights of the ubiquitinated proteins in heat-shocked CFRK cells were between 18 kDa and 24 kDa by immunoblot assay.These results suggested that there were more ubiquinated proteins in the heat-shocked CRFK cells than in the pre-heat-shocked cells.
