Since 20-year reform and opening-up to the outside world, the private industry of Zigong has developed gradually, become more and more economically competitive, and played a more and more important role in the economic structure of Zigong. This paper analyzes the problems of private economy and its countermeasures based on the research on its status quo.

Developmental Changes of the LPL mRNA Expression and Its Effect on IMF Content in Sheep Muscle

This study investigates the developmental changes of the lipoprotein lipase （LPL） mRNA level in sheep muscle and its effect on intramuscular fat （IMF） accumulation. Male Kazak and Xinjiang Merino sheep at 2-120 days old were selected. Six animals of each breed were slaughtered at 2, 30, 60, 90, and 120 days （only the Xinjiang Merino sheep at 120-day old were available） to collect samples from longissimus dorsi muscle for the purpose of determining the IMF content and extracting total RNA that was used to investigate the developmental changes of the LPL mRNA expression by real-time PCR. The results showed that in male Kazak sheep, the IMF content increased with the progress of development and there were significant differences （P〈0.05） between the age groups. However, there was no difference （P〉0.05） between age groups in Xinjiang Merino sheep. Furthermore, the IMF content of the male Kazak sheep was significantly higher （P 〈 0.01） than that of the Xinjiang Merino sheep aged from 30 to 90 days. The highest LPL mRNA expression appeared at day 2 and it was significantly higher than that of all other age groups （P 〈 0.01）, while animals at 60-day old had the lowest LPL mRNA expression in the male Kazak sheep. In Xinjiang Merino sheep, the highest one occurred at 30-day old （P〈0.01）, followed by a continuous decrease to the lowest level at 90-day old, and then it started to increase slightly. At 2 to 60-day old, the LPL mRNA expression was negatively correlated to the IMF content （r=-0.625, P 〈 0.05） in male Kazak sheep, but no such relationship was detected in the male Xinjiang Merino sheep.

Feature Selection Method by Applying Parallel Collaborative Evolutionary Genetic Algorithm

Feature selection is one of the important topics in text classification. However, most of existing feature selection methods are serial and inefficient to be applied to massive text data sets. In this case, a feature selection method based on parallel collaborative evolutionary genetic algorithm is presented. The presented method uses genetic algorithm to select feature subsets and takes advantage of parallel collaborative evolution to enhance time efficiency, so it can quickly acquire the feature subsets which are more representative. The experimental results show that, for accuracy ratio and recall ratio, the presented method is better than information gain, x2 statistics, and mutual information methods; the consumed time of the presented method with only one CPU is inferior to that of these three methods, but the presented method is supe rior after using the parallel strategy.

Knowledge Economy-The Sustainable Development Economy

Reviewing evolution of natural resources utilization mode in different economic formation, the paper elaborates the meanings of knowledge economy, and points our that the cause of unsustainabte development is the acute contradiction between the taw of ecosystem and the law of economy. It also points out that the essence of sustainable development is the harmonious relation between economy and the ecosystem. Therefore. the resources allocation should be considered from the aspect of the market demand and the aspect of the supply of t he ecosystem. That is to say, firsthy, the scale and pace of economy growth must be adapted to the supply capability of the ecosystem under the current technology, Secondly, based on the supply ability of the ecosystem, we should make it clear how to make limited resources allocation attains equilibrium between market supply and demand. The paper clarifies that in the mode of knowledge economy; we may transform the way of economy growth, form optimum economy structure, change the base of resource supply, strengthen the supply capability of ecosystem expand the production-possibility frontier, and finally accomplish the eco-economy coordinated development through the innovation of institution and technology. The essence of sustainable development and the sustainable characteristics of knowledge economy that were discussed above determine that knowledge economy is an economy of sustainable development.

Economic Growth:Theoretical Arguments about Resources,Environment and the Limit Issue & the Choices Faced by the Human Being

The relationship between man and nature seems highly diverse during the evolving process of human society. Numerous destructive consequences incurring from the carly stage of the industrialization led to man＇s severe concern about ecological and environment issues. In 1972, a book entitled “The Limits To Growth” ushered in a worldwide argumentation campaign, and forced man to realize that the bearing capacity of ecological surroundings is finite, and the quantity of resources is numbered as well. Admittedly, the human advance in science and technology, from the long-term viewpoint, is capable of discovering new types of energy and resources. However, each specific period of human history is always endangered due to the crisis of energy and resources. Therefore the core of the retainable development lies in variation of the outdated pattern of economic growth as well as pursuit to the new substitutes.

Design Method Based on Routing Tree for Topology Update in Ad Hoc Network

A design method based on the tree-model structure for topology update is presented. The routing tree of every node in network is built by defining the data structure and is used to save the topology information of neighbor nodes. The node topology update is accomplished by exchanging their routing trees. For saving the precious wireless bandwidth, the routing tree is sparsely shaped before sending by pruning the redundant routing information. Then, the node topology update is implemented by using algorithms of inserting and deleting routing sub-trees.

Reactivity of Schiff Base Manganese（Ill） Complexes with Different Pendants toward the Hydrolysis of p-Nitrophenyl Picolinate

This paper describes the catalytic performance of two manganese（III） complexes with mono-Schiff base ligands as artificial hydrolases towards the hydrolysis of p-nitrophenyl picolinate （PNPP）. Observations reveal that the one complex （ MnL22C1 ） containing morpholine pendants exhibits 1.2-1.7 fold kinetic advantage over the other one （MnL12C1） containing benzoaza-15-crown-5 group. Especially, optimum molecule structures using a Gaussian 03 software confirm that MnL2CI indeed possesses a relatively open linked site for the approaching of PNPP, result- ing in higher efficiency due to a convenient association between substrate （PNPP） and MnL2C1. In addition, the steric hindrance of two pendants, i.e., benzoaza-15-crown-5 and morpholine, may be a main influencing factor for tuning catalytic activities of the synthesized Mn（III） catalysts. Both Mn（III） catalysts used here were found to have fine tolerance to the operated temperature and pH. Related kinetic and thermodynamic analyses were also given to demonstrate their structure-activity relationships （SAR） of both catalysts used.

p-Nitrophenyl Picolinate Cleavage by Unsymmetrical Bis-Schiff Base Manganese（Ⅲ） and Cobalt（Ⅱ） Complexes with Aza-Crown Ether or Morpholino Pendants

The unsymmetrical bis-Schiff base manganese（III） and cobalt（II） complexes with either benzo-10-aza-crown ether pendants （MnL1Cl, MnLZCl） or morpholino pendant （MnL3Cl, CoL3） have been employed as models for hy- drolase by studying the kinetics of their hydrolysis reactions with p-nitrophenyl picolinate （PNPP）. A kinetic model of PNPP cleavage catalyzed by these complexes is proposed. The effects of complex structures and reaction temperature on the rate of PNPP hydrolysis have been examined. All four complexes exhibit high catalytic activity and the rate increases with pH under 25℃. The complexes of ligands containing a crown ether group exhibit higher catalytic activities than the non-crown analogues. The catalytic activity of the complexes follows the order Mn（III） 〉 Co（II） under the same ligands.
