Significant Breakthrough in Industrial Test of the "Methanol to Olefins" Process Developed by Dalian Institute of Chemical Physics,Chinese Academy of Sciences

A process of ＂Methanol or Dimethylether to Olefins＂ developed by Dalian Institute of Chemical Physics （DICP）, designated as the DMTO process, has attained great success in industrial scaling up testing. DICP, by collaborating with the Xinxing Coal Chemical Co., Ltd. of Shaanxi Province and the Luoyang Petrochemical Engineering Co. of the SINOPEC Group, operated successfully a 50t（methanol）/d unit for the conversion of methanol to lower olefins, with a methanol conversion of close to 100%, and a selectivity to lower olefins（ethylene, propylene and butylenes） of higher than 90%. On 23rd August, the industrial test project has passed a state appraisal. The experts of the Appraisal Group, headed by Prof. YUAN Qingtang, academician of Chinese Academy of Engineering, drew the conclusions that the DMTO process, by utilizing a proprietary SAPO-34 catalyst system and a recycling fluidized bed reaction system for the production of lower olefins from methanol, is the first unit in the world having a capacity of producing nearly ten thousand tons lower olefins per year. The technological level of the industrial test is at a leading position internationally. This accomplishment will provide a sound base for the subsequent commercialization of the DMTO process.

Advances of microgravity sciences in China are introduced. The research works include ground-based study and space experiments. In the recent years, the main means still are theoretical analysis, numerical simulation, ground-based experiment, and short-time microgravity experiments of drop tower. Besides, many space experiment projects are arranged. SJ-10 recoverable satellite will carry out 19 scientific experiment projects. Nine of them are for microgravity Sciences. The other ways for space microgravity experiment are with the help of Chinese Shenzhou spacecraft, Chinese Tiangong space laboratory, and Chinese space station in the near future. The Chinese space station will become main platform of Chinese microgravity sciences experiment in space.

Relationship between meeting the recommendations for physical activity and health-related quality of life in adult Chinese Internet users

Background: The benefits of a recommended level of physical activity on physiological health indicators such as morbidity and mortality are well-accepted, but few researches has addressed whether or not the association between the recommended level of physical activity and a health-related quality of life (HRQOL) exists in the Chinese adults. Purpose: The present study examined whether the recommended physical activity (PA) would be associated with HRQOL in the Chinese adults. Methods: Cross-sectional data were collected through an internet-based survey. Total of 1394 Chinese adults responded the International Physical Activity Question- naire-Chinese version examining whether individuals met the recommended ACSM/AHA PA guideline. Demographic data were also obtained. HRQOL was assessed with the Medical Outcomes Survey Short Form-36 questionnaire (SF- 36). Multivariate analyses of covariance were utilized to examine differences in multidimensional scales of the SF-36. Results: In both genders, the recommended group had significantly higher physical functioning, vitality, and mental health scores than the inactive group. Significant differences in role physical, general health, social functioning scores were only found among the recommended and insufficient male groups. Conclusion: Individuals who attained the recommended level of PA had better scores on some dimensions of HRQOL than those who did not.

Providing Physical and Mental Health Support Using Medical Examination Data and Perceived Health

Without ascertaining workers’ perceived health, it is difficult to achieve behavioral modification even if health guidance is conducted. To investigate physical and mental health support emphasizing “positive health,” we used the Total Health Index (THI) survey with the purpose of elucidating the association between medical examination data and perceived health. After obtaining medical examination data from 90 men, we analyzed their responses to the THI survey. The results suggested that age and abnormal medical examination data are associated with physical and mental complaints. In the analysis by age group, we found that men in their 20s had more complaints of irregularity of daily life on the THI scale. The group who responded that they were not getting enough sleep had higher mean values of total cholesterol and fasting blood sugar. The group who responded that their meals were irregular had higher mean values of Body Mass Index, aspartate aminotransferase, and alanine aminotransferase. As confirmed by the THI, continuously supporting lifestyle improvement is important. The THI of the “health guidance” group indicated fewer physical health complaints and more aggression/extroversion than the “normal” group. In those for whom health guidance was applicable, participants who were “obese” and “hypertensive” had more aggression/extroversion and lesser extent of nervousness. Based on these findings, it was suggested that meaningful, personalized health support can be developed.

Food Physics as One of the Dominant Parts of the Interdisciplinary Science of the XXI Century

The Mathematical and Physical Theory of Rational Human Intelligence: Complete Empirical-Digital Properties;Full Electrochemical-Mechanical Model (Part I: Mathematical Foundations)

The design of this paper is to present the first installment of a complete and final theory of rational human intelligence. The theory is mathematical in the strictest possible sense. The mathematics involved is strictly digital—not quantitative in the manner that what is usually thought of as mathematics is quantitative. It is anticipated at this time that the exclusively digital nature of rational human intelligence exhibits four flavors of digitality, apparently no more, and that each flavor will require a lengthy study in its own right.

A retrospective view on the history of natural sciences in XX-XXI

The presented paper is dedicated to a new ret-rospective view on the history of natural sci-ences in XX-XXI cc, partially including the sci-ence philosophy (mainly, the problems of the scientific realism, i.e. the correspondence of science to reality) and also a novel scheme for different classes of sciences with different ob-jects and paradigms. There are analyzed the chosen “great” and “grand” problems of phys-ics (including the comprehension of quantum mechanics, with a recently elaborated new chapter, connected with time as a quantum obs- ervable and time analysis of quantum processes) and also of natural sciences as a whole. The particular attention is paid to the interpretation questions and slightly to the aspects, inevitably connected with the world- views of the res- earchers (which do often constitute a part of the interpretation questions).

Third Millennium Physics Come out from the Mind of Ettore Majorana

From the silence of a monastery where he voluntarily enclosed himself for many years, the enlightened mind of Ettore Majorana produced a new mathematics and a new physics which foster a historic leap in human knowledge. Here we quote his theory and some salient aspects of the construction of a machine, realized by Rolando Pelizza, which have demonstrated how exact and real the hypotheses of Ettore were. The world now has magnificent and new possibilities： it can annihilate matter, produce infinite energy at practically no cost, transmute matter and transfer it to other dimensions. But this knowledge, which we call Third Millennium Physics, will not immediately be available to humanity and first it is necessary to go through a process of gradually acquiring consciousness and change in human attitudes.
