Published: February 2023

Abstract:
High-speed motorized spindle is the core component of high-speed machining machine
tools, and thermal error is the main factor affecting the machining accuracy of the motorized spindle.
Reducing thermal error has become the most important research topic in the case of motorized
spindles. The development status of the cooling strategy of the motorized spindle is explored, and
the methods to improve the cooling efficiency of the motorized spindle are discussed. Some representative
research results of the cooling strategy of motorized spindles at home and abroad are reviewed.
Based on summarizing the related research results on cooling strategies for the core components,
such as the stator, rotor and bearing of the motorized spindle, this paper analyzes the advantages
and disadvantages of various cooling strategies and their applicable working conditions,
and the future development direction of motorized spindle cooling strategies is discussed. The combination
of various channel structures and the cooling strategy of the stator outer ring of the motorized
spindle will improve the cooling efficiency of the motorized spindle, and research on the motorized
spindle core cooling will become more and more important. In addition, the cooling system
of the motorized spindle bearing, stator, and rotor can be improved at the same time, and the heating
problem of the motorized spindle can be solved.

中國古代詩論發展和樂論、畫論和書論的關係——中國文學批評史研究的一個新思考
Authors: 張 少康

LANGUAGE NOTE | Document text in Chinese only.
中國文學理論批評史的研究這二十年來有了很大的發展，如何進一步深入是大家一直在思考的問題。前兩年有些學者强調範疇研究，認爲那是批評史研究深入的關鍵，但是熱鬧了一陣，並未見有實績。我是不贊成這種主張的，範疇研究固然重要，但那是要建立在對批評家和批評專著深入研究基礎上的，否則就祇能是趕時髦的泛泛之論，把一些類似的概念作一點簡單排比，是不會有實際成效的，甚至會造成誤導。我認爲中國古代文學批評史的研究要深化，有一個問題特别值得我們重視，這就是必須把文學批評的研究和藝術批評的研究緊密地結合起來，考察他們之間的交互影響和發展演變。(撮要取自內文首段)

Published: February 2023

Abstract
The paper consists in analyzing some of the researches on specialized literature regarding to gripping systems and proposing a new solution for a gripping mechanism that can fulfill the increasing requirements imposed by the flexible manufacturing systems regarding the orientation and positioning of parts with variable shape and dimensions. Some general consideration on state of the art in the field of gripping mechanism are presented and main development direction are indicated. The second part of the paper contains in the development of new gripper constructive solution. From the literature analysis the main requirement for a gripping system is the multi-tasking ability. The proposed designed solution uses four parallel open-close jaws/fingers controlled by two electric motors. The actuation of the jaws/fingers for clamping the part is accomplished by a primary motor. The main contribution/improvement refers to the introducing of a second/supplementary motor that is used for the movement of the position of the jaws in order to transform the gripper clamping system from a four-jaw construction to a two-jaw gripper construction and vice versa, thus increasing range of clamped parts.

Published: February 2023

Abstract
This paper intends to introduce a new approach in cycloidal reducers design. The usual design uses rotary pins as teeth on the ring gear (or stator as well) and an appropriate conjugate profile on the cycloidal disc (or rotor as well). This study proposes a new approach: to use rotary cylindrical pins as teeth on the rotor and an appropriate conjugate profile on the ring gear (or cycloidal ring) according with the rules of gearing. The main achievements of this paper focus on the synthesis of 2D internal profile of the cycloidal ring in transverse section. Some theoretical achievements and computer aided simulation results are briefly presented in this paper. This 2D profile is useful mainly for cycloidal reducer computer aided simulation and optimization but also for manufacturing purposes (by contour milling on CNC machines).
The Influence of the Starting Structure and Water Model on the Conformation Transition of Poly(N-Isopropylacrylamide) Thermoresponsive Polymer - In Silico Studies
Authors: Băcăiţă Elena Simona , Mocci Francesca 
Published: February 2023

Abstract
Molecular dynamics (MD) simulations are intensively used to obtain information on the microscopic behavior of a system and to evaluate certain properties which they determine at macroscopic level. But, as well as setting up an experiment in a “wet” laboratory, also setting up a simulation in a virtual enviroment implies many variables that influence the results. Two of the variables are the starting structure of the system and the water model in which it is solvated.
The present work aims to identify an optimal combination of this two variables able to reveal best the transition from an extended to a collapsed conformation for poly(n-isopropylacrylamide) (PNIPAM) thermoresponsive polymer.
Usage of Atmospheric Sounding to Characterize the Meteorological Events on the Night of 23/24 August, 2022
Authors: Apetroaie Cosmina , Bostan Diana-Corina , Timofte Adrian , Bostan Sorin , Cazacu Marius-Mihai 
Published: February 2023

Abstract
At the end of summer, the episode of atmospheric instability in the Moldavia region, is attributed to the predominantly eastern circulation, which directed air masses from the Asian continent to Romania. This context is the result of the presence of a high-pressure area, located in northern Siberia and extended to north-eastern Europe. Romania was located in the flow of the eastern circulation, behind the warm front.
The emersion of unforeseen factors, as was the case with the transport of dust from the dry regions of Asia, due to background of a circulation from the east, or the specificities of the relief, make it difficult to forecast the phenomena associated with instability. In this sense, atmospheric soundings are among the most used tools in forecasting atmospheric instability. In this sense, we used atmospheric soundings estimated by the GFS and ECMWF numerical forecast models to analyze the atmosphere vertically. Also, the cross-section profiles drawn in the EUMeTrain application showed the differences between the west and the east of Moldavia and described the vertical atmosphere in the analysed interval.
The evolution of the convective episode was described through satellite images. The forecast models anticipated the instability but did not estimate the amounts of cumulative precipitation. The increase in the amount of precipitation was, among other things, attributed to the existence in the atmosphere of Moldavia of dust particles that acted as condensation nuclei that increased the amount of precipitation. High concentrations of dust were also noticed after consistent rain showers, as explained by Cloudnet data processed.
The analysed case was one of the most representative instability episodes for summer of 2022 in Moldavia and played a decisive role in the soil water reserve.
Here’s how air quality and changes in the atmosphere have a major impact on the environment. The notable frequency of detected electrical discharges, was probably also the result of the presence in the atmosphere of suspended dust particles (due to a natural air pollution process), driven towards the Moldavia region.
On the Effectiveness of Insolvency and Bankruptcy Code, 2016: Empirical Evidence From India
Authors: Abhirami A , Rahul T 
Published: February 2023

Abstract
The Indian insolvency regime has undergone a historic change with the introduction of the Insolvency and Bankruptcy Code, 2016. This paper empirically analyses the effectiveness of the Code in the Indian economy. The paper also studies the insolvency frameworks that existed in India, the distinguishing features, and the legal framework of the Code. The analysis of the current status of the Indian insolvency regime with time series and cross-sectional data clarifies the non-performing assets trajectory, recovery rates, and time required under different recovery mechanisms, a summary of cases under the new Code and the status of India in the international insolvency systems. The empirical evidence of this study suggests that the Code is an improvement over its predecessors in terms of recovery rates, resolution of non-performing assets, and resolution costs. The Code should be subjected to necessary improvements to evolve and become a foolproof mechanism. Suggestions to that effect are offered in the final section.

Quality assurance for non-contrast CT of the abdomen and pelvis during a period of supply chain disruption leading to iodinated contrast shortage in the emergency department setting
Authors: Calimano-Ramirez Luis Fernando , Hernandez Mauricio , Singh Anmol , Gumus Kazim Ziya , Marfori Wanda , Virarkar Mayur K. , Lall Chandana , Gopireddy Dheeraj Reddy 
Published: February 2023

Objectives:
Iodinated contrast media (ICM) shortage crisis due to COVID-19 lockdowns led to a need for alternate imaging protocols consisting of non-contrast computed tomography (CT) for abdominal complaints and related trauma indications in emergency department (ED) settings. This quality assurance study aims to evaluate clinical outcomes of protocol modifications during ICM shortage and identify potential imaging misdiagnosis of acute abdominal complaints and related trauma.

Material and Methods:
The study included 424 ED patients with abdominal pain, falls, or motor vehicle collision (MVC)-related trauma who had non-contrast CT of the abdomen and pelvis in May 2022. We accessed the initial complaint, order indication, non-contrast CT results, any acute or incidental findings, and any follow-up imaging of the same body region with their results. We evaluated their association utilizing Chi-squared tests. We assessed sensitivity, specificity, and positive/negative predictive values using follow-up scan confirmation.

Results:
Across initial complaint categories, 72.9% of cases were abdominal pain, and 37.3% received positive findings. Only 22.6% of patients had follow-up imaging. Most confirmed original reports were for abdominal pain. We also found three reports of missed findings. There were significant associations between complaint categories and initial non-contrast CT report results (P < 0.001), as well as initial complaint categories and whether the patient received follow-up imaging or not (P < 0.004). No significant associations were found between follow-up imaging results and initial report confirmation. Non-contrast CT had 94% sensitivity and 100% specificity, with positive and negative predictive values 100% and 94%, respectively.

Conclusion:
Rate of missed acute diagnoses using non-contrast CT for patients presenting to the ED with acute abdominal complaints or related trauma has been low during the recent shortage, but further investigation would be needed to verify and quantify the implications of not routinely giving oral or intravenous contrast in the ED.

Motivations of Rural Tourism Entrepreneurs: Conceptual Theory Building Using the Qualitative Study Results
Authors: Kenebayeva A.S. , Xiaotian Zh. 
Published: February 2023

Abstract
Object: This paper aims to investigate the entrepreneurial motivations of various categories of rural tourism entrepreneurs, particularly highlighting the differences between Opportunity, Necessity, and Irrational entrepreneurs with a deep focus on commercial, social, irrational, as well as mixed intrinsic motives in start-up initiatives.
Methods: This research adopts the qualitative research method. Twenty-five rural tourism entrepreneurs in Central Asia were studied in-depth, using a purposive sampling strategy.
Results: The research revealed a specific category of rural tourism entrepreneurs defined as Irrational Entrepreneurs, which do not connect their initiative and activities with an opportunity to gain philanthropic benefits. Irrational Entrepreneurs are characterized by an extremely social dominance degree in their business motivations.
Conclusions: For contributing to the conceptual theory building, the “Dominant Motivation Degrees” model is suggested. The model indicates the impact of social and commercial components of intrinsic motives on an integral nature of entrepreneurial motivations.
THE ECONOMIC MECHANISM OF ENSURING RESOURCE CONSERVATION AND NATURAL USE IN THE CONDITIONS OF GLOBAL CHALLENGES

Published: February 2023

Russia's war against Ukraine worsened the ecological situation, creating the prerequisites for a nuclear and energy hazard for the entire civilized world. Violating all international conventions and agreements the aggressor country threatens everyone with an energy collapse. Accordingly, such actions lead to the destabilization of processes and, at the same time, form new approaches to ensuring energy, environmental, and food security. An intensive transition to alternative sources of electricity is beginning, and new approaches to environmental protection and resource conservation are being formed. Despite the intensity of hostilities, national producers are forced to work and ensure production stability to balance the economy. Accordingly, there is an urgent need to improve the economic mechanism for resource conservation and nature management, which will increase the competitiveness of national production on world markets and the post-war recovery of the economy.
The article's purpose is to justify the economic mechanism of ensuring resource conservation and nature management by modern global challenges.
The mechanisms for fulfilling Ukraine's environmental obligations have been systematized, among which the most significant is determined to be: the introduction of an environmental management and audit system, the creation of a system for stimulating the use of waste as a source of energy for the production of heat and electricity, implementation of a system for trading quotas for greenhouse gas emissions. It is substantiated that bioenergy is one of the alternative energy sources for the production of which Ukraine has significant potential. Agricultural biomass is a promising energy source thanks to favorable natural and climatic conditions. Compared to other sources, it is the most accessible and cheaper energy source, which involves waste-free production aimed at meeting the population's needs in energy resources and food. It has been investigated that the main obstacles to the cultivation of energy plants and the production of thermal energy on this basis are that they are not included in the classification of crops, and the legislative framework and regulatory policy in this area have yet to be created. A conceptual diagram of the economic mechanism for resource conservation and nature management has been developed. It is based on organizational-methodological, financial, and informational development, taking into account modern principles, tools, and methods of its implementation and considering global challenges.

Published: February 2023

Background: Cerebral ischemic stroke is caused due to neurovascular damage or thrombosis, leading to neuronal dysfunction, neuroinflammation, neurodegeneration, and regenerative failure responsible for neurological deficits and dementia. The valid therapeutic targets against cerebral stroke remain obscure. Thus, insight into neuropathomechanisms resulting from the aberrant expression of genes appears to be crucial. Objective: In this study, we have elucidated how neurogenesis-related genes are altered in experimental stroke brains from the available transcriptome profiles in correlation with transcriptome profiles of human postmortem stroke brain tissues. Methods: The transcriptome datasets available on the middle cerebral artery occlusion (MCAo) rat brains were obtained from the Gene Expression Omnibus, National Center for Biotechnology Information. Of the available datasets, 97 samples were subjected to the meta-analysis using the network analyst tool followed by Cytoscape-based enrichment mapping analysis. The key differentially expressed genes (DEGs) were validated and compared with transcriptome profiling of human stroke brains. Results: Results revealed 939 genes are differently expressed in the brains of the MCAo rat model of stroke, in which 30 genes are key markers of neural stem cells, and regulators of neurogenic processes. Its convergence with DEGs from human stroke brains has revealed common targets. Conclusion: This study has established a panel of highly important DEGs to signify the potential therapeutic targets for neuroregenerative strategy against pathogenic events associated with cerebral stroke. The outcome of the findings can be translated to mitigate neuroregeneration failure seen in various neurological and metabolic disease manifestations with neurocognitive impairments.
