Mg81Ni19-8wt.% REO (oxides of Lanthanum and Cerium) alloys were successfully prepared using mechanical alloying method with Mg-Ni alloy and REO powder. Phase analysis, structural characterization, and microstructure imagine of the alloys were conducted using X-ray diffraction (XRD), metallurgical microscope, and transmission electron microscopy (TEM) methods. Multi-phase structures, including the primary phase of Mg2Ni and several secondary phases of Mg + Mg2Ni, MgNi-LaO, and MgNi-CeO, were found in in the as-cast Mg81Ni19- 8wt.% REO alloys. XRD and TEM results showed that Ce exhibits variable valence behavior at various stages, and the addition of REO promotes the nanocrystalline of the alloy. The hydrogen absorption capacity of ball-milled Mg81Ni19 and Mg81Ni19- 8wt.%REO alloy for 2 h at 343 K is 1.34 wt.% and 1.83 wt.%, which are much larger than 0.94 wt.% of as-cast Mg81Ni19 alloy. The addition of REO led to a decrease of the thermal decomposition temperature of the alloy hydride by approximately 20 K and a reduction of the activation energy of the hydrogen desorption reaction by 10% and 13%, respectively.

To study the effect of inorganic electrolyte solution on graphite flotation, 19 kinds of inorganic electrolytes, including nitrate, chloride and sulfate were selected as experimental electrolytes. The flotation experiment was carried out on graphite and the contact angle and surface potential of the interaction between inorganic electrolyte solution and graphite were studied. The results show that flotation effect and flotation rate of the three ion valence inorganic electrolytes follow the order: nitrate < chloride < sulfate and univalent < bivalent < trivalent (except Ba(NO3)2 and Pb(NO3)2). When the ion valence are the same, the larger the ion atomic number, the better effect on graphite flotation. Cations in inorganic electrolyte solutions are the main factors affecting mineral flotation. When the cationic type and concentration are the same, different flotation effects are attributed to different anions. For low ion valence inorganic electrolyte solution with weak foaming effect, a certain dose of frother can be added appropriately to improve the flotation effect of graphite. The high ion valence inorganic electrolyte solution has strong foaming effect, and it is not necessary to add a frother. The principle of inorganic electrolyte solution promoting graphite flotation is analyzed from the aspects of liquid phase property, gas–liquid interface property, contact angle and surface potential. It is proved that inorganic electrolyte solution as flotation medium can promote the effective flotation of graphite.

Since soil salinization imposes various adverse effects on plants, research on how to relieve salt stress from plants is extremely urgent. We synthesized a new type of cerium-doped carbon quantum dots by a hydrothermal synthesis method. Characterization shows that the carbon quantum dots have a small and uniform particle size, high stability, high water solubility and biocompatibility. Mung bean seeds were soaked in CDs:Ce solutions under a concentration gradient (0.25, 0.5, 1, 2, 3 mg/ mL) and germinated under salt stress (150 mM NaCl). Compared with salt stress, the addition of CDs solutions effectively enhanced the ability of plants to relieve salt stress. The relieving effect on mung bean plants was the most significant after treatment with 2 mg/mL CDs:Ce, and the main root length, plant height and leaf length in comparison with the case of salt stress increased by 83%, 80%, and 60%, respectively. Chlorophyll content, peroxidase activity, superoxide dismutase activity and catalase activity, total protein content increased by 90%, 77%, 76%, 77% and 76%, respectively, malondialdehyde and proline The content decreased by 83% and 77%. Inductively coupled plasma mass spectroscopy proved mung bean plants absorbed CDs:Ce, but the absorption of NaCl decreased by 21.8%. Fluorescence imaging showed CDs:Ce was absorbed by roots, and transferred from the vascular system and apoplastic pathways to stems and leaf veins, and mainly aggregated in intercellular gaps, the vascular system, leaf veins, cilia and stomata. Stereomicroscopy showed that CDs:Ce induction increased the stomatal opening by 15.7%, and improved metabolic efficiency and NaCl excretion from the plants. Hence, CDs:Ce shows great potential in protecting crops from abiotic stress.

Bangladesh enjoys an advantageous geographical position. It has been a transit station for businessmen from South Asia, Southeast Asia, Central Asia and even Europe since ancient times. It is located at the intersection of China Economic Circle, South Asia Economic Circle and ASEAN Economic Circle, and is an important country along the belt and road initiative. The “Belt and Road” initiative was supported by Bangladeshi Prime Minister Sheikh Hasina. Since the “Belt and Road” initiative was put forward, China and Bangladesh have achieved remarkable results in policy communication, facility connectivity, smooth trade, capital financing and people-to-people communication. However, China and Bangladesh still face challenges in the political, security, economic and social fields to jointly build the “Belt and Road” initiative. In the new period, China and Bangladesh should strengthen political communication, promote the docking of China-Bangladesh development strategies, strengthen facility connectivity and industrial cooperation, promote cultural exchanges, promote the upgrading of cooperation between the two countries, and jointly build a high-quality “Belt and Road” initiative.

The rule of law principle has been established in modern society as a core value in domestic political governance. It evolves from social contract theory and is meant to rein in the almighty and powers from its beginning and later applies to all. In general, international law has become an essential pillar of the present international order. The recent rise of unilateral actions has posed threat to the international rule of law tradition. Equality in international relations, Pacta Sunt Servanda, and good faith implementation of treaty obligations are the essentials of the international rule of law, which provides predictability and stability to the stake holders in the international community. It also represents the fundamental common values of thousands of years of human civilization. Upholding the principle of international rule of law goes to the fundamentals and natures of human beings. Thus, maintaining international rule of law is a guarantee for a better world for all.

An automated note generation system has been designed that improves the disadvantages of creating notes in music using BMS programs. In this paper, using FFT algorithm, the sound scale was extracted through frequency analysis of audio file and converted to color information. This was used to create automatic notes and balance the game in the rhythm game. In the case of non-complexed music such as children's songs, sound extraction was possible, but music such as K-pop, which had complex voices mixed, lacked accuracy. In this paper, the existing research on the relationship between pitch and color was objectively quantified and the system was designed to determine the balance and difficulty of the game based on the synesthesia felt by human.

The implementation of this law will positively impact the future investment environment of China. This article analyses the background and evolution of the legislation procedure, the highlights and features of the law compared with earlier related laws in the field of foreign investment of China, and the impact and insufficiency of the law, together with the issues following the implementation of the law.

Understanding why individuals behave unethically is an important topic for both theory and practice, especially in the current environment where people experience much more stressful events. The current research aims to examine the relationship between peoples’ experienced stress and their attitude towards unethical consumption behavior, as well as the underlying mechanism. Empirical findings from a survey of 451 participants suggest perceived stress serves as an important indicator of people’s tolerance of unethical activities, and that this relationship is mediated by chronic construal level and materialism value. Specifically, stressed individuals tend to develop low-construal mindsets and more materialism values, both of which further increase their tolerance of ethically questionable behaviors. The present research highlights the importance of stress on consumer ethics and contributes to prior literature in three ways. Firstly, the current study adds to the literature on consumer ethics by examining a new predictor of consumers’ ethical beliefs, which enriches the understanding of why some consumers act more ethically than others do. Secondly, to the best of our knowledge, little prior literature has examined the effect stress on ethical beliefs. The current research for the first time examines the effect and the mechanism and reveals the mediating roles of construal level and materialism value. Thirdly, the present research finds that stress increases low-level construal, leading to unethical beliefs. This finding broadens the scope in construal level theory by suggesting that chronic construal level predicts individual ethical judgments.

The US Space Resource Exploration and Utilization Act 2015 aroused heated discussions. The international community has not yet reached consensus on the application of the concept of “common heritage of mankind” in the Moon Agreement. In accordance with the non-appropriation principle in the Outer Space Treaty, outer space is not subject to national appropriation. However, there is a need to balance the common interests of the international society and the interests of the States and private entities which invest heavily in the space resource exploration. The unilateral approach of the US by adopting a national law is not an ideal way to deal with space resource exploration. As a major space-faring nation, China should take a proactive approach in both national legislation and international cooperation in this field. At the international level, China should consider establishing an appropriate international regime for space resource management.

Canine cloning have been succeeded for a decade. To obtain in vivo matured dog oocytes, Serum progesterone (P4) level were employed for ovulate determination. However, accuracy of P4 methods is not satisfied. The aim of this study was to compare both methods of serum estradiol (E2) and P4 on the accuracy of canine ovulation determination. Canine serum P4 and E2 concentration during both proestrus and estrus were detected. Correlation between accuracy of each method and environment temperature were analyzed. Following ovulation, oocytes were collected by surgery. As a result, higher percentage of mature oocytes was obtained when using E2 (56.43%) as compared to P4 (39.60%). Accuracy of P4 increased from spring (30.76%) to summer (47.92%) and decreased in autumn (37.50%) and winter (29.16%) gradually. Especially, E2 maintained about 50% to 65% whatever the season and temperature. Correlation analyze showed that dynamic of P4 accuracy highly correlated with environment temperate (Rp4=0.862) but E2 could not be affected by the temperature (RE2=0.199). To determine whether obtained oocytes by E2 method could be used for canine cloning, twenty canines were selected as oocyte donors, and two puppies were produced after somatic cell nuclear transfer(SCNT) and embryo transfer(ET) with the oocytes by E2 method. In conclusion, comparing to the P4 method, the E2 is an accuracy and reliable method for canine cloning.

China’s foreign investment has been growing rapidly since 1990s. In this course, the first investor-state arbitration case raised by a mainland Chinese investor, Ping An v. Belgium, drew attention to an important issue – jurisdiction ratione temporis in successive international investment agreements. It is controversial in theory and practice as to whether the basic principle of non-retroactivity should apply to the dispute settlement clause in a successive agreement. This is especially true when tribunals are interpreting different kinds of jurisdictional clauses. This paper will take the Ping An Case as an opportunity to thoroughly analyze the issue of temporal jurisdiction in successive international investment agreements. Based on such analysis, this paper will also do reflection on relevant articles in China’s existing investment agreements, providing suggestions to China regarding the issue of jurisdiction ratione temporis, in an effort to make arbitration more certain and avoid possible dismissal, as occurred in the Ping An Case.

Taguchi’s experimental design was employed in the melt spinning of molten mesophase pitch to produce carbon fibers. The textures of the obtained carbon fibers were radial with varied crack angles, as observed by scanning electron microscopy and polarized optical imaging. The diameter, crack angle, preferred orientation, and tensile modulus of the produced samples were examined to investigate the influence of four spinning variables. The relative importance of the variables has been emphasized for each characteristic. The results show that thicker carbon fiber can be obtained with a smaller entry angle, a higher spinning temperature, a reduced winding speed, and an increased extrusion pressure. The winding speed was found to be the most significant factor in relation to the fiber diameter. While it was observed that thicker carbon fiber generally shows improved preferred orientation, the most important variable affecting the preferred orientation was found to be the entry angle. As the entry angle decreased from 120° to 60°, the shear flow was enhanced to induce more ordered radial alignment of crystallite planes so as to obtain carbon fibers with a higher degree of preferred orientation. As a consequence, the crack angle was increased, and the tensile modulus was improved.
