The concepts regarding the people as the focal point, the dignity, the worth of the human being, as well as larger aspects of freedom, and other basic concepts within the Charter of the United Nations, guide the right direction of action for the realization of the right to development. The purpose and principles of the United Nations establishment in the Charter constitute the basic legal protection of the right to development. Values of peace, international dialogue, and international cooperation show the right path to the realization of the right to development.展开更多

Especially, the density functional theory(DFT) and time-dependent density functional theory(TDDFT) methods for HNP monomer are introduced. Moreover, the "our own n-layered integrated molecular orbital and molecular mechanics"(ONIOM) method(TDDFT:universal force field(UFF)) is used to reveal the aggregation-induced emission(AIE) effect on the ESIPT process for HNP in crystal. Our results confirm that the ESIPT process happens upon the photoexcitation for the HNP monomer and HNP in crystal, which is distinctly monitored by the optimized geometric structures and the potential energy curves. In addition, the results of potential energy curves reveal that the ESIPT process in HNP will be promoted by the AIE effect. Furthermore, the highest occupied molecular orbital(HOMO) and lowest unoccupied molecular orbital(LUMO) for the HNP monomer and HNP in crystal have been calculated. The calculation demonstrates that the electron density decrease of proton donor caused by excitation promotes the ESIPT process. In addition, we find that the variation of atomic dipole moment corrected Hirshfeld population(ADCH) charge for proton acceptor induced by the AIE effect facilitates the ESIPT process. The results will be expected to deepen the understanding of ESIPT dynamics for luminophore under the AIE effect and provide insight into future design of high-efficient AIE compounds.展开更多

In the case of new curriculum reform in our country, many scholars or teachers are exploring betterand more reasonable ways to improve English teaching. The appearance of action research means that a new method is provided tohelp scholars or teachers to study English teaching in our country. Therefore, this article will give a concrete introduction to actionresearch and also do some reflection on using action research to study English teaching in our country.展开更多

Both can be separated into smaller sections which are in the case of physical life: glowing star state with atomic evolution, solidification of the surface, the appearance of C, O<sub>2</sub> and water and abiotic chemical evolution. During that period of time kinds of external and internal energy were effective only through physical-chemical way. In the case of biological life, the 1<sup>st</sup> section started with the appearance of the first living unit and ended with the beginning of photosynthesis. The 2<sup>nd</sup> one lasted from the start of photosynthesis till the appearance of the first two man-like creatures. The 3<sup>rd</sup> one began from that point of time and lasted till 1778 and the last one the 4<sup>th</sup> has existed since that date. Since the appearance of the first living unit biological accumulation of external energy and mainly C but not only, emission of CO<sub>2</sub> gas, metabolites, heat, transformation and loading of the earthly environment as well as natural mutation of organisms that is the biological evolution have flown. When photosynthesis began biological fixation of solar energy/photon and free atmospheric CO<sub>2</sub>, as well as production of free O<sub>2</sub>, have also started beside the former events and the biological evolution has continued. No unnatural event had happened in these two sections. The fate of the 3<sup>rd</sup> and the 4<sup>th</sup> sections— that is the anthropoid time—has been determined by the unnatural effects of man kind. The most important altering events are: the number of the inhabitants, the use of fire, agricultural production, domestication of animals, formation and maintenance of industry, trade, vehicle-park, denaturation of the surface of the Earth and contamination of soil, atmosphere and waters etc. Finally, ideas for the solution of the climate problems which are mainly the results of the 3<sup>rd</sup> and 4<sup>th</sup> sections will be discussed.展开更多
文摘基于耗氧速率(OUR)和脱氢酶活性(DHA)对异常水质条件以及毒性物质的存在都非常敏感,考察二者作为评价污泥活性方法的可行性,并对两个指标进行比较。结果表明,不同 pH值的化工污水以及含有苯酚、甲醛和甲醇等毒性物质的化工污水对 OUR 和 DHA 具有非常一致的变化趋势,可以通过 OUR 和 DHA 的测定同步反映出异常水质对污泥活性的影响。
