Published: May 2021

In order to a the flow of the plane flow field induced by the inner rod rotates and revolves in the cylinder, the Fluent software is used to numerically simulate the plane flow field of the eccentric annulus generated by the planetary motion of the rod string and based on the superposition principle. The velocity distribution and secondary flow of the two flow fields, as well as the fluid force on the inner rod are analyzed. The calculation results show that the flow field induced by the eccentric rotation of the inner rod and the self-rotation of the outer cylinder is quite different from the planetary motion of the inner rod. When rotation of the inner rod has the same direction with the revolution direction, the fluid velocity distribution near the wall of the inner rod is that the velocity on the narrow space side of the annulus is large, and on the wide space side is small. There is a critical value of eccentricity for secondary flow appears when the eccentricity is greater than this value. When rotation of the inner rod is contrary to the revolution, the fluid velocity distribution near the wall of the inner rod is that the velocity on the wide space side of the annulus is large, on the narrow space side is small. Different eccentricity has obvious secondary flow phenomenon where appears in a wide gap and close to the inner rod. When the inner rod revolves, there is a critical value of eccentricity, the inner rod is pushed outward by the fluid force when the eccentricity is less than this critical value. On the contrary, the inner rod is pushed inward. When rotation and revolution are reversed, the critical value of eccentricity increases, when the rotation and revolution are in the same direction, the critical value of eccentricity decreases.

Authors: Qu Xia , Li Ran
Published: May 2021

In recent years, while the direct investment of Chinese enterprises has made rapid progress in foreign direct investment, it has also shown a trend of “blindness” and “irrationality”, which has brought huge overseas investment risks. The reason is largely due to foreign investment enterprises ignore the host country’s legal system. This paper uses 82 foreign direct investment data of Chinese listed companies in 30 countries (regions) from 2010 to 2019 as a research sample to analyze the impact of the host country’s legal system on the performance of Chinese companies’ foreign direct investment. The results show that the performance of Chinese enterprises’ investment in the country has gradually improved with the improvement of the economic development level of the host country, the soundness of the legal system of the host country has been continuously improved. The restraining effect of the soundness of the host country’s legal system on investment performance is more obvious in state-owned enterprises and investments involving sensitive industries or key areas. In addition, the performance of investment enterprises will gradually improve with the increase in the density of labor unions and the international investment experience of enterprises.

Authors: Hu Muxin , Zhao Dichen , Jin Qiuchi , Li Hanrui , Wang Wenmin
Published: May 2021

In recognition of the increasing demand of energy and the worsening environmental problems linked with fossil fuels usage, algal biofuel has been proposed as one of the alternative energy sources. It has become one of the hottest topics in renewable energy field in the new century, especially over the past decade. In this review, we summarized the characteristics of different types of algae biofuels. Besides, an in-depth evaluation of the systematic cultivation and practical application of algae have been conducted. Although algal biofuel has a great potential, its unacceptably high cost limits the large-scale industrialization. In order to resolve such restrictions, feasible methods of improving the large scale production and practical application of algal biofuels are proposed. Future efforts should be focused not only on the cost reduction and innovation techniques, but also towards high value by-products to maximize economic benefits. Our results are dedicated to provide valuable references for subsequent research and guidelines on algae biofuels field.
Effects of the addition of coal tar pitch-based mesocarbon microbeads on the preparation of mesophase pitch
Authors: Gong Xin , Liu Xiaodong , Liu Dong
Published: May 2021

Mesophase pitch was prepared by co-carbonization of the hydrocracking tail oil (HCTO) and coal tar pitch-based mesocarbon microbeads (MCMB). The effects of the addition amount of coal tar-based MCMBs on the C/H atomic ratio, softening point, carbon residue, optical texture, aromatic lamellae stacking order degree, and chemical reaction kinetics of mesophase pitch were investigated. The results show that MCMB can be used as a nucleating agent to accelerate the nucleation of mesophase spheres and reduce the energy barriers for the formation of the anisotropic phase. However, excessive MCMB greatly increases the viscosity of the pitch matrix and weakens the mobility of condensed aromatic macromolecules, leading to the formation of mesophase pitch with a mosaic structure and poor lamellar orientation. When the addition amount of MCMB is 5 wt%, the mesophase pitch with a large domain texture, high aromatic lamellar stacking order degree, and low softening point can be formed. This work provides a pathway to efficiently prepare mesophase pitch without catalyst removal.

Authors: Liu Chunbao , Zhang Sheng
Published: May 2021

Antarctica, with a large number of ice sheets, is among the last unexplored places on Earth. The subglacial lakes beneath these ice sheets have been isolated from the outside world for up to 35 million years, containing a diverse group of marine organisms and other materials. Its unique hydrological environment provides insights regarding microbial evolution and past climates on Earth, which have become central to interpreting the process of landscape evolution and assessments of possible future climate change. Clean sampling of subglacial lake water without introducing surface biological or other type of contamination has long been a goal of the international scientific community. The overlying ice thickness can reach thousands of meters and in conventional deep ice drilling, drilling fluids are employed while the boreholes exposed to the atmosphere. The only method for penetration is thermal drilling with the rate proportional to the vertical diameter of the drilling rig, which requires the drill body to be as thin as possible. The melted ice/water in the upper borehole will refreeze immediately once penetrating into the ice layers. Cables, thereby, need to be configured inside the drilling rig since separate cables from the external surface are not applicable in such cases. The drill rig comprises the motor-driven winch, outer surface heating system, control system as well as sampling system, totaling 600 kg in weight. Gear reducers are required during the cable lowering/lifting operations with a maximum outer diameter of the winch of 140 mm and a high-precision automatic synchronization between the reducers and cable lowering/lifting system is required. An automatic tension sensor along with a winch control system is designed to realize thee automatic synchronization between the gear reducers and the cable lowering/lifting system through servo control.

Reception of literary works in the original and translation. A case study: Students’ responses
Authors: Perminova Alla
Published: May 2021

The present case study applies the Reception Model of Literary Translation that places a high value on multiplicity and subjectivity of a target readership’s response to a source text. The article highlights a three-stage experiment that analyzes Literary Translation majors’ responses to Yuriy Vynnychuk’s novelTango of Deathin the original and in Michael M. Naydan and Olha Tytarenko’s translation. The data on the students’ response was collected by means of brainstorming sessions, in-class discussions, written reports, essays, and questionnaires. The informants agreed that on a large scale the translators succeeded in recreating the fusion of tragedy and humor of Vynnychuk’s writing. However, on a small scale, certain translation decisions initiated polemics. Thus, some students criticized the recurrent translators’ decision to alter the author’s syntax, which is one of Vynnychuk’s stylistic idiosyncrasies. Whereas others would fully approve of this technique, stating that otherwise the text would be incomprehensible for an English reader. Another stumbling block was associated with culturally biased units. Some students criticized the literality of conveying a number of Ukrainian set expressions, others saw in it a manifestation of a foreignization strategy. The students’ feedback prompted a conclusion about the experiment helping to build up the learners’ confidence in their professional expertise, boost their self-esteem and empathy, as well as to prepare them for actual translating projects of their own.
Construction as basic translation unit: A case of referring to blind people in English and Ukrainian
Authors: Danylchenko Iryna , Zhovinsky Yana
Published: May 2021

The research focuses on the variations in the degrees of equivalence manifested in English and Ukrainian constructions referring to blind people. In this study, patterns consisting of two or more words referring to people with decreasing ability to see, all forms sight impairment are termed blindness-constructions. The results show that in translating from English into Ukrainian blindness-constructions reveal varying degrees of equivalence: from exact correspondence in case of immediate constructions to some sort of constructional mismatch in extended patterns. High degree of equivalence with the immediate blindness-constructions is explained by their fixed form: they include combinations of words with the nounsimpairment, sight / visionand the adjectiveblinddescribing stable attributes without reference to any specific situation. The modified English blindness-constructions rarely have equivalents readily available in Ukrainian, since their modifying elements broaden or narrow the meaning of immediate constructions restricting their usage to particular contexts in source and target languages. The extended blindness-constructions exhibit a mismatch across the languages. These constructions are made up of two immediate or modified ones and represent the generalized models of situations where translators, forced by the non-existence of identical patterns, have to resort to various strategies.

Published: May 2021

Based on the interactional translation model, this paper discusses the role of translator’s competence in the success of translation for business. Via complex analysis of translations of advertising texts as discourse acts that are pragmatically oriented and relatively uniform in their aims, the authors establish an extralingual criterion for measuring the quality of their translation – the ability to satisfy the same cognitive/communicative needs and exert the same influence as the source texts on the audience with the different cultural background. Arguing that translator’s /interpreter’s qualifications should include awareness of the target community’s ethnical and business culture coupled with the sense of responsibility for the results of translation as an intercultural discourse act, the authors formulate implications for the formation of strategic competence in teaching professional business translators.

Erfahrungsgemäß bieten Urtinkturen und Tiefpotenzen den Phytotherapeuten in der Tiermedizin wichtige Therapie-Optionen. Es hat sich als sinnvoll erwiesen, insbesondere solche Arzneipflanzen als Tiefpotenzen einzusetzen, deren therapeutische Breite gering ist. Dies gilt vor allem bei Patienten, deren Metabolisierungsfähigkeiten bekanntermaßen eingeschränkt sind (Neugeborene, Alte, Patienten mit Leber- und/oder Niereninsuffizienz, Karnivore, insbesondere Feliden), aber auch bei Patienten, deren Metabolisierungsfähigkeiten nicht bekannt sind (Exoten, Reptilien, Amphibien) 8.

Objective To evaluate whether continuation rates with the 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS) up to 5 years after placement differed between women using the method exclusively for contraception and those using the device for medical reasons alone.

Methods A retrospective cohort study was conducted in a family planning clinic with 5,034 LNG-IUS users: 4,287 using the method exclusively for contraception and 747 for medical reasons alone. The continuation rate at 1 to 5 years of use was calculated by life table analysis.

Results Initially, the continuation rate was significantly higher in the contraception group: 85.8 versus 83.4 and 77.4 versus 76.0 per 100 women-years in the 1st and 2nd years of use, respectively. There were more discontinuations due to bleeding/spotting in the medical reasons group in the first two years. The discontinuation rate according to reason for use was not significantly different from the third to the fifth year of use. No women discontinued due to amenorrhea in either group.

Conclusion The continuation rate was significantly higher in the contraception group in the first two years of use. Amenorrhea was not a reason for discontinuation in either group, suggesting that counselling in this respect was adequate. Nevertheless, counselling could perhaps have been better with regards to the expected long period of bleeding and spotting in the first two years after placement.

Objective The aim of this study was to investigate functional anatomy of the craniolateral bundle (CrLB) and caudomedial bundle (CdMB) of caudal cruciate ligament in normal Beagles.

Materials and Methods Twelve stifle joints of 12 Beagle cadavers that were euthanatized for reasons other than musculoskeletal disease were used. Anatomical characteristics of femoral and tibial attachment regions of the caudal cruciate ligament were described, and location and area of the footprints of the CrLB and CdMB were objectively determined. The CrLB was artificially divided into two equal fibre bundle units and the CdMB was artificially divided into four equal bundle units. Changes in the fibre arrangement were recorded during stifle range of motion, and the tension of each fibre bundle unit at various stifle joint angles was objectively measured.

Results The CrLB was attached to the intercondylar fossa of the femur, and the CdMB was attached to the medial surface of the medial condyle of the femur. The centre of the CrLB attachment site was located craniomedial to that of the CdMB on the tibia. During stifle range of motion, each divided fibre bundle unit in the CrLB and CdMB was twisted externally. The tension of entire CdMB tended to be higher than that of entire CrLB at 180 to 135 degrees of the stifle angles. In full extension angle, the tension of entire CdMB was 1.55 times higher than that of entire CrLB.

Clinical Significance This study contributes to understanding of the biomechanics and the function of the caudal cruciate ligament, which help to elucidate the pathophysiology of caudal cruciate ligament tear and to develop stifle joint stabilization surgery.

Published: May 2021

Background While electronic health records have been collected for many years in Taiwan, their interoperability across different health care providers has not been entirely achieved yet. The exchange of clinical data is still inefficient and time consuming.

Objectives This study proposes an efficient patient-centric framework based on the blockchain technology that makes clinical data accessible to patients and enable transparent, traceable, secure, and effective data sharing between physicians and other health care providers.

Methods Health care experts were interviewed for the study, and medical data were collected in collaboration with Ministry of Health and Welfare (MOHW) Chang-Hua hospital. The proposed framework was designed based on the detailed analysis of this information. The framework includes smart contracts in an Ethereum-based permissioned blockchain to secure and facilitate clinical data exchange among different parties such as hospitals, clinics, patients, and other stakeholders. In addition, the framework employs the Logical Observation Identifiers Names and Codes (LOINC) standard to ensure the interoperability and reuse of clinical data.

Results The prototype of the proposed framework was deployed in Chang-Hua hospital to demonstrate the sharing of health examination reports with many other clinics in suburban areas. The framework was found to reduce the average access time to patient health reports from the existing next-day service to a few seconds.

Conclusion The proposed framework can be adopted to achieve health record sharing among health care providers with higher efficiency and protected privacy compared to the system currently used in Taiwan based on the client–server architecture.

Diallyl sulphide (DAS), the pungent component of garlic, is known to have several medicinal properties and has recently been shown to have radiomitigative properties. The present study was performed to better understand its mode of action in rendering radiomitigation. Evaluation of the colonogenic ability of hematopoietic progenitor cells (HPCs) on methocult media, proliferation and differentiation of hematopoietic stem cells (HSCs), and transplantation of stem cells were performed. The supporting tissue of HSCs was also evaluated by examining the histology of bone marrow and in vitro colony-forming unit–fibroblast (CFU-F) count. Alterations in the levels of IL-5, IL-6 and COX-2 were studied as a function of radiation or DAS treatment. It was observed that an increase in proliferation and differentiation of hematopoietic stem and progenitor cells occurred by postirradiation DAS administration. It also resulted in increased circulating and bone marrow homing of transplanted stem cells. Enhancement in bone marrow cellularity, CFU-F count, and cytokine IL-5 level were also evident. All those actions of DAS that could possibly add to its radiomitigative potential and can be attributed to its HDAC inhibitory properties, as was observed by the reversal radiation induced increase in histone acetylation.
