Unfortunately, data available in related literature focus on the anti-cancer properties of compounds derived from edible plants, while very little is known about those derived from non-edible plants. And thus, the underlying mechanisms of their anti-cancer effects are yet to be elucidated. This review collates the available data on the anti-cancer activities of six phytochemical-derived compounds from edible and non-edible plants, i.e.展开更多

The results show that the decadal climatic forcing for the last decade is one-order bigger than that prior to the year 1900, and in the case of no control on the emission of the greenhouse gases the climatic forcing for the year 2100 will be almost 4 times as much as now.展开更多

Prevention of blindness is related to many factors. It is related to many factors, such as science and technology, economy and social behavior. There are worldwide activities by WHO, NGOs and other functions to promote the prevention of blindness in the world. More than 90% of blind population lives in developing world. Cataract is the top causes of blindness which is curable. Onchocerciasis is an endemic disease in west Africa and cent...展开更多

This is particularly the case in Central-Eastern China （CEC）, where the two major cities of Beijing and Tianjin are located, in the Yangtze-River Delta （YRD） with the city of Shanghai, and in the Pearl-River Delta （PRD） with the mega-city of Gnangzhou. Space observations show that the atmospheric aerosol load in these three regions is considerably higher than, for example, in the urbanized regions of Europe and North America. The high aerosol concentrations in these regions have raised many environmental problems, such as impact on human health, visibility, and climate changes. In this paper, several crucial issues regarding aerosol pollution in these highly populated regions （CEC, YRD, and PRD） are discussed, including （1） when the aerosol load starts to rapidly increase in these regions; （2） how the high aerosol concentrations affects the environment; and （3） what the potential consequences are under possible low aerosol load in these regions. Discussion on these crucial issues might lead to some insight for better understanding of the characterizations of aerosol pollution due to the rapid economical development in China.展开更多

The cascade hydropower stations use water from the same river; in a sense, they form a cluster of hydropower stations which are linked together by the river stream. The dispatch and management of the cascade hydropower stations in a river basin differ from those of an ordinary single hydropower station. Without doubt, unified dispatch can facilitate the full harnessing of hydraulic resources and is in a better position to fulfill the objectives in the development of river basin. As a result, more and more river-basin cascade power stations around the world implement unif ied dispatching.展开更多

Shipping After entering into the 1990’s, the ship-building industry, badly affected by the long recession of the world shipping market, has been growing very slowly, while the competition has been a fierce one. From the shares enjoyed by the major shipping countries in the world, we can see that the first one is Japan which occupied 38%; South Korea came to the second,obtaining 15％; the third is Germany, being 8%. The shipbuilding industry in America is shrinking, owing to the high cost of production. Up to 1993,Japanese ship yards had still been in difficult situation, and many Japanese ship owners would rather order new ships from South Korea because the rising value of Japanese yen made it expensive to build in domestic yards. Nowadays, Japanese shipbuilding industry is exposed to the problem of scarce of labour force. The Korean shipbuilding industry,展开更多

Histopathologically, PD is characterized by a severe loss of dopaminergic neurons in the substantia nigra and cytoplasmic inclusions composed of insoluble protein aggregates （Lewy bodies）, which lead to a pro- gressive movement disorder including the classic triad of tremor, bradykinesia, and rigidity.展开更多

The key auto parts are classified into 25 categories which are listed below:EFI system, spark plug, valve, tappet, piston & piston ring, bearing bush, turbo charger, diesel engine high-pressure pump, aluminium radiator, filters, diaphragm spring clutch, constant velocity universal joint, vacuum servo booster & master cylinder, non-asbestos friction materials, brake tube, brake hose, steering gear, steering ball joint, shock展开更多
