Progress in the Technology for Desulfurization of Crude Oil

The poor quality of crude oil obviously leads to high sulfur contents of oil products, and the technology for desulfurization of crude oil is urgently needed so that the sulfur contents in petroleum product could be reduced from the root. This paper describes the progress in technology for desulfurization of crude oil. The present technologies for desulfurization of crude oil include caustic washing, dry gas desulfurization, hydrodesulfurization （HDS）, etc. The new combined technologies for desulfurization of crude oil being studied are： biodesulfurization （BDS）, hydrogenationbacterial catalysis, the microwave-catalytic hydrogenation, the BDS-OD-RA desulfurization and oxidative desulfurization in electrostatic fields, and the ultrasonic/microwave-catalytic oxidation applied in our lab, with their development trends being also discussed.

New Progress on the Coal Fines Affecting the Development of Coalbed Methane

Objective The production of coal fines is very common in the development of coalbed methane（CBM）in the eastern margin of the Ordos Basin,China.A large amount of produced coal fines seriously affect the productivity of CBM wells（Wei Yingchun et al.,2013）.Therefore,the production problems of CBM wells caused by coal fines have attracted extensive attention.

CAS Action Plan for the Development of Western China Progressing Smoothly

Since CAS is charged with the key task of carrying out strategic, fundamental and forward-looking studies for this country, it is incumbent upon CAS scientists to take an active part in the National Program for the Development of Western China. This is also an important part of the national Knowledge Innovation Program (KIP) spearheaded by CAS. Over the past two years, CAS has made a series of remarkable advances in Western China with regard to the development of research bases, exploration of crucial scientific problems, the training of talented people, and providing consultation services for decision makers.With the furtherance of the national drive to develop the country's western region, CAS will step up its efforts and increase its funding, to make more and greater contributions to the overall development of the region.

Research Progress and Present Situation of Tridimensional Reservoir Development

Designing special well patterns, tridimensional reservoir development selects a variety of wells and uses the gravity energy to maximize the hydrocarbon recovery. It's a new development model to implement the oil and gas exploitation economically and efficiently. It is suitable for both huge oiliness altitude reservoirs and large dip-angle sandstone reservoirs, and more for the carbonate reservoirs developed in high-angle fractures, volcanic reservoirs and metamorphic reservoirs.

Concrete Progress Made on LM-7 Development

It was announced recently that important progress had been made on the development of the LM-7 launch vehicle. Assembly welding of the booster oxidizer tank for propulsion system test-firing, the first structural product of LM-7, has been performed at Capital Aerospace Machinery Corporation, CALT. The 2.25m diameter oxidizer tank is only 0.17cm in thinness in the thinnest area and is nearly 13m in length increased from the current 4.5m, which is the

Progress and Development Strategy of Biomass Energy Utilization Technologies in China

I. Preface Biomass includes the residues of agriculture, forest and stock breeding, as well as straw, algae and energy crops. In its broad meaning, biomass is a kind of organic matter produced by the photosynthesis of plants, which is not only renewable, but also contains plentiful energy.

Study on Sowing Date for Mechanicaltransplanting Rice under Wheat-Rice Cropping System in Chengdu Basin

Nurturing sturdy mechanical-transplanting seedlings is the key to achieve high yield using mechanical-transplanting technology under wheat-rice cropping conditions in Chengdu Basin. In this study, super hybrid rice II You 602 was adopted as experimental material, to investigate the effects of sowing date on seedling growth,transplanting quality, growth process and yield of mechanical-transplanting seedlings in wheat-rice cropping region of Chengdu Basin, thus exploring supporting high-yield cultivation techniques for mechanical-transplanting technology in Chengdu Basin, Results showed that the appropriate sowing date for mechanical transplanting in wheatrice cropping region of Chengdu Basin was April 10-15, and the appropriate seedling age was 45-50 d, which led to the highest yield of mechanical-transplanting seedlings. Although postponing sowing was conducive to improving transplanting quality and increasing the percentage of earbearing tillers, it would result in lagged group growth, poor spike quality and reduced effective number of panicles, grain number, seed-setting rate, 1 000-seed weight and other yield components, thus declining the yield. Yield reduction rate would be above 10% with sowing date postponed by 15 d.

Targeting an oncogenic kinase/phosphatase signaling network for cancer therapy

Protein kinases and phosphatases signal by phosphorylation and dephosphorylation to precisely control the activities of their individual and common substrates for a coordinated cellular outcome. In many situations, a kinase/phosphatase complex signals dynamically in time and space through their reciprocal regulations and their cooperative actions on a substrate. This complex may be essential for malignant transformation and progression and can therefore be considered as a target for therapeutic intervention. p38γ is a unique MAPK family member that contains a PDZ motif at its C-terminus and interacts with a PDZ domain-containing protein tyrosine phosphatase PTPH1. This PDZcoupled binding is required for both PTPH1 dephosphorylation and inactivation of p38γ and for p38γ phosphorylation and activation of PTPH1. Moreover, the p38γ/PTPH1 complex can further regulate their substrates phosphorylation and dephosphorylation, which impacts Ras transformation, malignant growth and progression, and therapeutic response. This review will use the p38γ/PTPH1 signaling network as an example to discuss the potential of targeting the kinase/phosphatase signaling complex for development of novel targeted cancer therapy.
