In this paper, a novel scheduling strategy is proposed for a practical crude oil blending process. The objective is to keep the property of feedstock, mainly described by the true boiling point (TBP) data, consistent and suitable. Firstly, the mathematical model is established. Then, a heuristically initialized hybrid iterative (HIHI) algorithm based on a two-level optimization structure, in which tabu search (TS) and differential evolution (DE) are used for upper-level and lower-level optimization, respectively, is proposed to get the model solution. Finally, the effectiveness and efficiency of the scheduling strategy is validated via real data from a certain refinery.展开更多

Once occurs, the metastasis may cause life-threatening complications, such as bowel perforation, obstruction and bleeding. We reported an 83-year old man who presented with small bowel perforation secondary to metastatic lung cancer after being treated with erlotinib for 2 weeks. We propose that the use of erlotinib may be associated with the small bowel perforation and precautions should be taken by clinicians in initiating edotinib for primary lung cancer when there is bowel metastasis.展开更多

According to China＇s national conditions and the characteristics of the cultures, improve the research methodology of the national musicology, so that the national musicology can have the Chinese characteristics. The national musicology is an independent basic discipline in the university education. In China, the music education and research work in colleges and universities has an important role in the inheritance and development of the national music. In this paper, combined with the present situations of the music education in colleges and universities, from the perspectives of the education and the research, the author expounds the ideas of the development trends of the national musicology in the music education in colleges and universities.展开更多

Authentic presence requires three components： （1） honest exposition of a person＇s singular, essential being; （2） empathy towards the needs of other, distinct and separate from the self; and （3） mutual reciprocation, which means giving back or responding somewhat equitably to the other with whom the self is in communication, and accepting the same respondence from the other if afforded. The comprehension of Merleau-Ponty＇s ontology combined with Stanislavski＇s performance technique is uniquely suited to interpersonal communications in the ＇real world＇. Stanislavski＇s artistic vision demands an intensity of attentive involvement in order to achieve onstage authenticity. Merleau-Ponty provides supportive philosophical schematics, especially in his controversial but effective use of the expression ＇flesh＇. While this study may initially appear to focus on the artist, the development of interrelational skills is reliably applicable to anyone who desires to obtain a higher degree of authenticity in collaborative presence.展开更多

Advancements in molecular techniques have provided the proof of existence of autophagy in Plasmodium; however, its role（s） in malaria is only becoming to be understood. Nevertheless, some of the recently explored dimensions of autophagy in Plasmodium have indicated its fairly larger role in parasite survival and growth. But then, autophagy is also essential for host cell survival and defence. There is thus need to explore chemotherapeutic strategies to specifically target autophagy in both the parasite and host. This review focuses on autophagy pathways in Plasmodium and in host with a view to identify autophagy-related new drug targets for the discovery of novel antimalarial drugs.展开更多

An initial prototype robotic battery-type weeder was manufactured and tested to navigate and control weeds in rice paddy fields, but a speed was so slow, and thus second engine-type prototype was developed. A working acreage for weed control has been attained at and up to 0.8 ha/day. Small and young weed seedlings were uprooted and destroyed by passive devices in between rows as well as hills. This robot was smoothly navigated in between rows on behalf of the guidance under camera and sensor systems and control weeds with mechanical by the use of implements such as passive rotary weeders and then weeds would be cut and buried into the soils. Also muddy water was generated during operation which was none penetrated by light for weed germination to occur. The authors concluded that the robotic was an effective alternative implement to control weeds in lowland rice paddy as long as this tool was systematically introduced into the rice fields at three time intervals, viz. 15-20 days, 25-30days, and 35-40 days after transplanting of rice seedlings.展开更多
