The rapid increase of paddy field acreage has led to widely descending of groundwater table in well irrigation paddy area of low-land in Sanjiang Plain recent years. More and more “hanging pump” and partial over pumping phenomenon have been occurring in well irrigation paddy area of low-land. Therefore, the groundwater resources in Sanjiang Plain need to be recharged urgently. For solving the m...

Pollen and phytolith analyses were undertaken at the Jiangli site in Suzhou, Jiangsu Province, combined with studies on macrofossils by flotation. The concentration of pollen decreased while the percentage of Poaceae pollen in the profile increased from the late phase of the Majiabang Culture to the Songze Culture suggesting that human impact on the local environment intensified gradually. The ...

Background: Enzymatic corn wet milling (E-milling) is a process derived from conventional wet milling for the recovery and purification of starch and co-products using proteases to eliminate the need for sulfites and decrease the steeping time. In 2006, the total starch production in USA by conventional wet milling equaled 23 billion kilograms, including modified starches and starches used for ...

BACKGROUND Fine milling of dry lignocellulosic biomass, without prior chemical pretreatment, can produce a high percent theoretical yield of sugars during subsequent enzymatic saccharification. However, the high sugar yields, necessary for a commercial biofuels process, are costly, with the milling energy input, necessary to achieve such yields even exceeding the energy content of the biomass. ...

Particle size reduction is a simple means to enhance the dissolution rate of poorly water soluble BCS-class II and IV drugs. However, the major drawback of this process is the possible introduction of process induced disorder. Drugs with different molecular arrangements may exhibit altered properties such as solubility and dissolution rate and, therefore, process induced solid state modificatio...

In this paper the concept and first evaluation of the control principle of the MicroAssistant is presented. The MicroAssistant is an interactive surgical robot system to support the surgeon in microsurgical interventions especially in middle ear surgery. During those interventions the surgeon is often confronted with very small and sensitive structures. This fact conflicts with the exhausting m...

one of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. as a result, the tool would be worn and its life time would be reduced. therefore, in long time machining, it is essential to change inserts and tools, continiously. a milling tool with self rotary cutting inserts was designed and manufactured that enables i...

A study by Yongguan Zhu and co-workers has added greatly to our understanding of arsenic dynamics in the rhizosphere of paddy rice. Their finding that arsenic is sequestered in iron plaque on root surfaces in plants, regulated by phosphorus status, and that there is considerable varietal variation in arsenic sequestration and subsequently plant uptake, offers a hope for breeding rice for the ne...

cannot be had ; so I began enumerating all the waste products I could think of to replace it. As regards saw-dust, I knew of no quantity sufficiently large for the purpose. Paddy husking I knew was fairly common as a trade in the presidency, but I knew also that straw had been replaced in England by moss litter as stabling for horses and therefore concluded that straw or paddy husking were not ...

This study focused to identify the likelihood factors affecting on farmers’ higher gain from paddy marketing in the North Central Province of Sri Lanka, where the main paddy cultivation area of the country. The required data was drawn from the field survey carried out in three irrigation systems covering 257 farmers during July to August 2010. The empirical logit model was used to assess factor...
