However, translating these requirements directly into hierarchical structure will not ensure the integration of processes across organisational un its and guarantee desirable performance. Therefore, management and management li terature wonders: · How should we connect processes to the external environment within a strategi c framework · Which organisational structures do meet performance requirements · Which choices and freedom do we have within organisational structures · How and when do we implement organisational structures That the hierarchical structure does not meet as such the performance requiremen ts nor did it relate to these became already clear during case studies performed in the ’70s. The conclusion was drawn that organisational changes should affect working processes before they proof to be viable. This required the development of new approach through empirical studies and base d on literature. This led to the development of the organelle structure. The org anelle structure should connect to the strategy and the product flow. Thereto, a decision model has been developed for revealing these relations and the practic al implication. During a number of case studies this methodology has been refined and includes t he strategic choice between variants for the organelle structure with their own performance capabilities; we distinguish about 20 variants ranging between the f unctional organisation and the product flow organisation. These ranges of choice s however can be connected to different order entry points, stemming from logist ic concepts. This extends the performance to improved lead-times and improved c ontrol. Strategic choices relate the organelle structure to external performance criteria dictated by product/market-combinations: · lead-time · quality · costs and internal choices for performance criteria: · flexibility · productivity · resource utilisation · innovative performance. Case studies reveal the drastic improvements of the performance of operations an d manufacturing. The paper will discuss a few of these implementations to demons trate the impact. They also show how one derives the hierarchical structure from the choice for the organelle structure. Organelle structures do bridge the link of an industrial company to its environm ent and the internal possibilities, dictated by characteristics of product flow and process execution. The link to the environment results in a strategic framew ork for assessment of alternatives and possibilities. Choices for organelle stru ctures depend strongly on choices on the order entry points of the hardware flow and the specification flow.

However, this measurement has a very limited correlation with purity and quantity. The current study aims to determine the concentration of monoclonal antibody(mAb) and host cell proteins(HCPs) using a build-in UV/Vis monitoring during Protein A affinity chromatography and to optimize the separation conditions for high purity of mAb and minimizing the HCPs content. The eluate was analyzed through in-line UV/Vis at 280 and 410 nm, representing mAb and HCPs concentration,respectively. Each 0.1 column volume(CV) fraction of UV/Vis chromatogram peak area were calculated,and different separation conditions were then compared. The optimum conditions of mAb separation were found as 12 CV loading, elution at pH 3.5, and starting the collection at 0.5 CV point, resulting in high m Ab recovery of 95.92% and additional removal of 49.98% of HCP comparing with whole elution pool. This study concluded that UV/Vis-based in-line monitoring at 280 and 410 nm showed a high potential to optimize and real-time control Protein A affinity chromatography for mAb purification from HCPs.展开更多

Coarse rice varieties dominate Nepal’s rice processing industry, with a 42% share by total weight, followed by medium rice (34%) and fine varieties (less than 7%). Polished white rice (<em>Arwa</em>) was the dominant rice type in Nepal in the survey, followed by parboiled and steamed rice. The price and profit margins increased from coarse to fine rice varieties and from <em>Arwa</em> to parboiled and steamed rice. The cost of milling also followed a similar trend. The rice milling industry in Nepal largely influences the adoption or non-adoption of any specific type of rice variety by dictating specific brands in the market and this has important implications for rice research and development. The rice processing industry of Nepal was unable to compete with the Indian rice milling industry because of: 1) low profit margins due to the high cost of rice production and procurement, 2) a lack of economies of scale, 3) a lack of milling technologies for long and extra-long and steamed rice in the country and a lack of investment to modernize rice milling technology, and 4) unavailability of paddy throughout the year locally. Millers were willing to upgrade their rice milling technology to include high throughput parboiling, steamed rice as well as long and extra-long grain rice. This will be a strategic decision in counteracting the ever-increasing rice imports in Nepal. We believe that the findings of the study will be vital for formulating an appropriate rice research, development and rice processing strategy for Nepal to achieve food and nutritional security and the Sustainable Development Goals.展开更多

[Methods] Orthogonal test( L_(16)(4~3)) was designed to investigate the optimal soaking time,decocting time and bean curd proportion for processing Aconiti Kusnezoffii Radix by bean curd. The contents of monoester alkaloids and diester-alkaloids were measured as the evaluation indexes. [Results]The contents of monoester alkaloids were 0. 11%,0. 07%,0. 062% and 0. 048% respectively under the four levels of soaking time,were0. 081%,0. 066%,0. 074% and 0. 067% respectively under the four levels of decocting time,and were 0. 070%,0. 072%,0. 080% and0. 073% respectively under the four levels of bean curd proportion. The content of diester-alkaloids was all below 0. 034%. The influence intensity of the three factors on the content of monoester alkaloids ranked as soaking time > decocting time > bean curd proportion. Under any of the above conditions,the content of diester-alkaloids was below the limit of Chinese Pharmacopoeia. The content of diester-alkaloids was reduced obviously with the increased use of bean curd.

文摘Background:The herbs should be processed by different methods before use,and the efficacy and toxicity of Chinese herbal medicines may change,which may enhance efficacy and reduce toxicity after processing.Gansui(Kansui radix)is a common clinical herbal medicine,and there are considerable changes in its toxicity and efficacy after processing.Gaocao(Glycyrrhizae radix et rhizome)has a detoxifying effect.Methods:Using the contents of euphorbiadienol and the alcohol-soluble extract of Glycyrrhizae radix-processed Kansui radix as evaluation indexes,response surface methodology was used to optimize the processing technology of Kansui radix by exploring the effects of Glycyrrhizae radix et rhizoma-addition amount,frying temperature,and frying time on the processing technology of Kansui radix.Meanwhile,response surface software was used to analyze experimental data to determine the processing parameters of Kansui radix by Glycyrrhizae radix et rhizoma.Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine is used to analysis the potential ingredients of Kansui radix and verify the potential ingredients by western blotting.Results:The technology of Glycyrrhizae radix et rhizoma-processed Kansui radix was optimized for the Glycyrrhizae radix et rhizoma-addition amount of 27%,frying temperature of 180℃,and frying time of 11 min.The network pharmacology analysis revealed that Kansui radix could cause kidney,liver,and heart injury by the PI3K/AKT signaling pathway.Kansui radix at high or low dose could decrease the ratio of p-AKT/AKT while Glycyrrhizae radix et rhizoma-processed Kansui could increase it.Conclusion:The model established by response surface methodology is relatively accurate and can predict the contents of euphorbiadienol and alcohol extract of processed Kansui radix.The toxic effects and its mechanism of action of Kansui radix and processed Kansui radix on kidney,liver,and heart,from the perspective of systems biology,have provided scientific evidence to its clinical application.
文摘A rice mill survey covering diverse rice processing companies in terms of their milling output, type of technology and year of establishment was conducted to understand the current situation of the rice milling industry and to identify enablers and barriers to its growth in Nepal. Coarse rice varieties dominate Nepal’s rice processing industry, with a 42% share by total weight, followed by medium rice (34%) and fine varieties (less than 7%). Polished white rice (<em>Arwa</em>) was the dominant rice type in Nepal in the survey, followed by parboiled and steamed rice. The price and profit margins increased from coarse to fine rice varieties and from <em>Arwa</em> to parboiled and steamed rice. The cost of milling also followed a similar trend. The rice milling industry in Nepal largely influences the adoption or non-adoption of any specific type of rice variety by dictating specific brands in the market and this has important implications for rice research and development. The rice processing industry of Nepal was unable to compete with the Indian rice milling industry because of: 1) low profit margins due to the high cost of rice production and procurement, 2) a lack of economies of scale, 3) a lack of milling technologies for long and extra-long and steamed rice in the country and a lack of investment to modernize rice milling technology, and 4) unavailability of paddy throughout the year locally. Millers were willing to upgrade their rice milling technology to include high throughput parboiling, steamed rice as well as long and extra-long grain rice. This will be a strategic decision in counteracting the ever-increasing rice imports in Nepal. We believe that the findings of the study will be vital for formulating an appropriate rice research, development and rice processing strategy for Nepal to achieve food and nutritional security and the Sustainable Development Goals.
