Authors: Li Jia
Published: March 2024

Under the innovation-driven development strategy, inter-governmental cooperation in regional innovation has proliferated, but the historical change logic of local government participation in innovation cooperation has not been explained yet. Based on the theoretical paradigm of historical institutionalism, this paper attempts to construct a "structure-history-action" analytical framework for local government participation in innovation cooperation. Based on the theoretical paradigm of historical institutionalism, this paper attempts to construct a "structure-history-action" analytical framework for inter-governmental cooperation in regional innovation. In the course of more than forty years of change, inter-governmental cooperation in regional innovation in China can be divided into four stages. In the course of more than forty years of change, inter-governmental cooperation in regional innovation in China can be divided into four stages. Firstly, it has been driven by structural conditions in macro-institutional change; secondly, 'path dependence' Firstly, it has been driven by structural conditions in macro-institutional change; secondly, 'path dependence' caused by political and cultural genes, administrative institutional traditions and the 'key nodes' that drive change. Finally, the perceptions and interests of local governments, as micro-actors, have profoundly shaped the direction of change. On this basis, the development path of inter- governmental cooperation in regional innovation is proposed: strengthening the top-level design of innovation cooperation and optimizing.

Authors: Zhang Zhongsen
Published: March 2024

The transformation of government functions is the key to comprehensively deepening the reform in China, and the reform of the administrative examination and approval Bureau has played an important role in the process of implementing the "separation of audit management". This kind of reform can effectively promote the construction of our country service-oriented government, has the important rule of law significance. As a new thing, the Administrative examination and approval Bureau, which originally served as a service center, has faced a series of difficulties in the process of promoting reform, including the fuzzy scope of examination and approval items, the lack of professional quality of examination and approval personnel, difficulties in departmental coordination, the unclear division of examination and approval and supervision, and the lack of effective supervision. There are many reasons behind these difficulties, such as conflict of interest, unitary reform mode, restriction of administrative management system and lack of consensus on the direction of reform. In order to overcome these difficulties, a series of measures can be taken, such as promoting local legislation, improving the professionalism of examination and approval personnel, promoting information sharing, and strengthening internal and external supervision, so as to better promote the reform of administrative examination and approval bureaus.

Published: March 2024

The fundamental reason why China has become the country with the largest global carbon emissions is that energy and its related industrial systems mainly rely on fossil resources. To this end, promoting the energy structure and related industrial systems from high carbon to low-carbon green development in a scientific and orderly manner will help achieve the "dual carbon" goals and support China's high-quality and sustainable development. Among them, technological innovation plays a crucial role. Under the dual carbon goal, Bengbu explores energy technology innovation - developing copper indium gallium selenium thin film solar power generation systems, providing new development ideas for reducing building carbon emissions and achieving friendly interaction between buildings and the power grid. This article will explore the feasibility of adjusting the energy structure through technological innovation to achieve carbon emissions peak and carbon neutrality goals, and then use multi-attribute decision-making models and other methods to explore the optimal path to achieve the "dual control" goal of emissions reduction. Based on life cycle assessment, the trade-off effect of renewable energy, economy, and environment will be explored, Finally, the inductive summary method is used to provide reference opinions for the formulation of follow-up policies to optimize energy structure and how to achieve green and low-carbon development.
Active microrheology of fluids with orientational order
Authors: Lintuvuori J. S. , Würger A.
Published: March 2024

We study the dynamics of a driven spherical colloidal particle moving in a fluid with a broken rotational symmetry. Using a nematic liquid crystal as a model, we demonstrate that when the applied force is not aligned along or perpendicular to the orientational order, the colloidal velocity does not align with the force, but forms an angle with respect to the pulling direction. This leads to blue an anisotropic hydrodynamic drag tensor which depends on the material parameters. In the case of nematic liquid crystal, we give an analytical expression and discuss the resulting implications for active microrheology experiments on fluids with broken rotational symmetry.

Translation Quality Assessment of Literary Texts: A Critical Analysis of Two Recent Arabic Translations of Orwell's Animal Farm (1945)
Authors: Abdulmoghni Riadh Ahmed , Al-Sowaidi Belqes Saif Abdulelah
Published: March 2024

This article aims to assess and evaluate the quality of two recent Arabic translations of George Orwell's Animal Farm (1945), the first one by Mohammed Hasan Alawi (2019) and the second one by Hiba Fathi (2020) using House's (2015) Translation Quality Assessment model. A mixed approach of qualitative and quantitative methods was employed. The qualitative method involved conducting a comparative analysis between the profiles of the source text and the two translations employing House's model (2015) to identify mismatches at the register parameter. The quantitative method was employed to quantify the overtly erroneous errors and determine whether statistically significant differences exist in the mean number of these errors between the two translations. The findings of the study show numerous mismatches, particularly at the three dimensions of register (field, tenor, and mode) which to some extent affected the ideational and interpersonal components of the textual function in both translations. The findings also indicate statistically significant differences between the two translations in terms of the frequency of overtly erroneous errors. The second translation exhibited a higher number of such errors compared to the first translation, primarily resulting from the breach of the target language system. The study concluded that the second translation was less adequate compared to the first translation.

Published: March 2024

تناول البحث جهود شيخ الإسلام ابن تيمية في تقرير أن الفطرة السليمة توافق العقيدة الصحيحة، حيث جاء البحث في وتمهيد، وثلاثة مباحث، وخاتمة، والمصادر والمراجع. فجاء التمهيد: في مفهوم الفطرة لغةً واصطلاحًا. والمبحث الأوَّل: في الفطرة السليمة موافقة للعقيدة ومكملة للشريعة. والمبحث الثَّاني: في الاستدلال بالفطرة السليمة على توحيد الربوبية. والمبحث الثَّالث: في الاستدلال بالفطرة السليمة في الرد على أهل البدع.

وجاءت أهم النتائج التي توصلت إليها كالآتي:

1- أنَّ فطرة الله سبحانه التي خلقهم عليها لو تركت بلا تدخل من البشر لأدّت إلى التوحيد الخالص وأنه لا إله إلا الله الخالق البارئ المهيمن، وأنه سبحانه القوي مالك الدنيا والآخرة.

2- أنَّ الفطرة السليمة توافق العقيدة الصحيحة وتدعو إليها لو تركت بلا تدخل من البشر، وقد استخدم شيخ الإسلام دليل الفطرة في إثبات الربوبية وإثبات وجود الصانع، فهذه الطريق هي الصراط المستقيم، التي دعا الله تعالى الناس منها إلى معرفة وجوده.

3- نقض شيخ الإسلام –رحمه الله- ما شهد به الحدوث، أو دل عليه الإمكان بعد تقديم المقدمات دون ما شهدت به الفطرة الإنسانية، فبيَّن أن هذا علم فطري ضروري لا بد لكل بشر من معرفته، وذلك أن إثبات الصانع علم فطري ضروري، فالفطرة دليل عقلي يعلم به إثبات الصانع، وما فطره عليه، وخلقه عليه من الإقرار بأنه ربه.

4- أن الخلق كلهم ولدوا على الفطرة، وأن القدر المشترك الكلي الذي بين افراد الموجودات هو ان أهل الفطرة متفقون على الإقرار بالصانع.

Authors: Martling Shaylee , M. Voorhees Jill , J. Erlenbusch Maggie , Nachtigal Isabel , E. Barnes Michael
Published: March 2024

Astaxanthin is a xanthophyll with unique properties that make it a potent antioxidant and photoreceptor. It is synthesized in lower trophic level organisms, such as microalgae, yeast, and some other microbes. It is also synthetically manufactured. The use of astaxanthin for pigmentation in aquaculture is well documented, as are the numerous benefits for humans from the consumption of astaxanthin. However, little research has been conducted on its potential health benefits to aquatic species. Astaxanthin has recently been identified as a semi-essential nutrient for some common aquaculture species, such as crustaceans and salmonids, but its effectiveness as a health supplement in aquatic species is unclear. This review aims to summarize the varied current uses of astaxanthin in aquaculture, as well as the potential effects of astaxanthin on the aquatic animal species which receive it.

Authors: Mostsfa Alsaied Alnaimy Habeeb , Abas Atta Mostafa , Sharaf Ahmed Kamel
Published: March 2024

Estimating the total body water (TBW) in the live animals using the Antipyrine (ANP) substance as a modified technique was the first objective of this research. TBW was estimated in vivo in ten native bovine calves using the conventional method (extrapolation technique) and also by the suggested modified method (equilibration technique). The averages of TBW in native bovine calves were 136.5±16 and 133.1±16 liters by convention and modified technique, respectively, without significant differences between the two techniques. The accuracy of the modified technique was 97.5 % as compared with the convention method and at the same time, the new method is an easy, simple, accurate and quick technique and more reliable. Estimation of heat adaptability of animals to heat stress conditions was the second objective of this research. Animals when exposed to high ambient temperature the TBW increases and consequently TBS (Live body weight-TBW) decreases with different percentages according to the animal response to stressful conditions. TBW or TBS values were estimated before and after heat stress exposure and the percentage change in TBW or TBS in the animal due to heat stress may be used for evaluating the animal's adaptability to heat stress. The percentage increase in TBW or the percentage decrease in TBS due to heat stress conditions may be used as an index for heat-tolerance coefficient (HTC). The most heat- tolerance animals are those with the highest HTC values.

Hayek’s Knowledge Problem and its Relevance in Organizational Management
Authors: Blakey Matthew A.
Published: March 2024

This paper discusses the enduring influence of Friedrich A. Hayek's contributions to economics and political philosophy, particularly in the context of modern decentralized management principles. Through his knowledge problem, Hayek can be seen as the ideological forefather of the modern management strategy of decentralization and can provide managers with practical insight into decentralized decision-making. The paper explores how Hayek's insights, specifically regarding the distributed nature of knowledge, intersect with the concept of decentralized management. By empowering employees, fostering collaboration, and leveraging local expertise, decentralized management addresses the limitations of traditional hierarchical structures. Comparing Hayek's "knowledge problem" with decentralized management as represented by the management scholar Peter Drucker, provides a theoretical foundation for agile and innovative organizational strategies. This paper concludes by offering practical insights for managers based on Hayek and Drucker’s work, such as encouraging bottom-up innovation and recognizing the limits of centralization for modern managers seeking to enhance adaptability and decision-making processes within their organizations.

Published: March 2024

To address the vibration problem in traditional W-W-type non-circular planetary gear trains during operation, this study proposes two new combinations of W-W-type non-circular planetary gear trains. The study focuses on analysing the transmission error and improving service performance. By utilizing the conjugate theory and the coordinate transformation theory, an accurate mathematical model for non-circular gears is derived. The transmission error models for the two combination forms of the non-circular planetary gear train are established using the incremental meshing line method. The analysis also examines the influence of eccentricity on the transmission error. Kinematic analysis of the multi-body dynamics model confirms that the new W-W type non-circular planetary gear train, formed by combining non-circular gears and cylindrical gears, exhibits superior transmission performance. Furthermore, a test analysis is conducted on the roller pumping unit test platform and the indicator diagrams of the pumping unit under various working conditions are obtained. The study concludes that the optimal matching mode for the sucker rod counterweight and motor frequency of the reversing device of the pumping unit is 20 kN and 20 Hz, and the dynamic balance of the pumping unit load can be achieved by adjusting the motor frequency.
Nonlinear Free Vibration Analysis of Functionally Graded Porous Conical Shells Reinforced with Graphene Nanoplatelets
Authors: Huang Xiaolin , Wei Nengguo , Wang Chengzhe , Zhang Xuejing
Published: March 2024

The nonlinear vibration analysis of functionally graded reinforced with graphene platelet (FG-GRC) porous truncated conical shells surrounded by the Winkler-Pasternak elastic foundation is presented in this paper. An improved model for evaluating the material properties of porous composites is proposed. Three types of porous distribution and three patterns of graphene nanoplatelets (GPLs) dispersion are estimated. Coupled with the effect of the Winkler-Pasternak elastic foundation, the nonlinear governing equations are developed by using the Hamilton principle. The Galerkin integrated technique is employed to obtain the linear and nonlinear frequencies of the shells. After the present method is validated, the effects of the pores, GPLs, the Winkler-Pasternak foundation, and the semi-vertex are investigated in detail. The results show that the linear frequency can be raised by increasing the values of the mass volume of the GPL and foundation parameters. In contrast, the ratio of nonlinear to linear frequency declines as the mass volume of the GPLs and foundation parameters rises. Furthermore, it is found that the minimum ratio of nonlinear to linear frequency can be obtained as the semi-vertex angle is about 55º, and the effect of porosity distribution on the linear and linear frequencies might be neglected.
Review Article: Early Recurrent Pregnancy Loss
Authors: Ahmed Suhail Hiba
Published: March 2024

Recurrent pregnancy loss, which affects 2%–5% of individuals, is just a significant concern for women's health. Uterine malformations, antiphospholipid syndrome, metabolic or endocrine diseases, as well as chromosomal abnormalities are among the often reported established reasons. Alternative aetiologies, like chronic uterine infections, hereditary thrombophilias, luteal stage insufficiency, or excessive male DNA disintegration rates, have been put forward yet remain regarded as debatable. The results for individuals who experience recurrent miscarriage had increased throughout time because to evidence-based therapies including surgical repair of chromosomal abnormalities, aspirin as well as anticoagulation in anticardiolipin disorder. About 50% of the instances, though, are still unsolved, so they are managed effectively with estrogen augmentation, anticoagulation, and/or immunostimulatory therapies. Regardless of the reason, couples who experience recurrent fetal death have a favourable long-term outlook and also the majority ultimately has a safe live delivery. Several miscarriages, though, may have a major psychological impact just on afflicted people, and numerous attempts are now being undertaken to enhance therapies or shorten the time it takes to conceive successfully. With an emphasis on inexplicable repeated fetal loss as well as the current usage of empiric therapies, this article reviews the recognised or contentious aetiologies as well as the suggested therapeutic approaches. As well, it covers the present use of pre - implantation genetic screening inside the treatment of repeated miscarriages.

Published: March 2024

Lakes in areas with fragile and dry steppe ecosystems are of great ecological and climatic importance, and  Buuntsagaan Lake is one of them in Mongolia. It is the largest lake of the Valley of the Lakes situated in the Khangai and the Gobi-Altai Mountain Range. In this study, we aimed to evaluate changes in the surface area of Buuntsagaan Lake between 1986 and 2022 and determine factors affecting it. We used Landsat satellite imageries to calculate the Modification of Normalised Difference Water Index for estimating the surface area of the Buuntsagaan Lake and assessed the dynamic changes in evaporation using Meyer's formula. Also, we performed field measurements at 74 points along the shore of Buuntsagaan Lake during the summer of 2022. The Kappa coefficient was used to examine the accuracy of the surface area. According to the results, it is observed that the surface area of Buuntsagaan Lake was the greatest in 1994 and 2000. However, the overall surface area decreased by 7.9% over the last 36 years, and the fluctuation in changes in the average annual surface area was around 0.34%. In addition, it is also indicated that the changes in the surface area of the lake were mainly affected by air temperature, the maximum speed of the wind, and the discharge of the Baidrag River. In conclusion, the tendency to decrease the surface area is expected to continue.
Хуурай хээрийн бүс дэх нуурын талбайн өөрчлөлт: Бөөнцагаан нуурын жишээн дээр
ХУРААНГУЙ: Хуурай хээрийн эмзэг экосистемтэй газар нутагт орших нуур нь экологи, уур амьсгалын хувьд чухал ач холбогдолтой бөгөөд Монгол орны нутагт орших Бөөнцагаан нуур нь тэдгээр нууруудын нэг юм. Бөөнцагаан нуур нь Хангайн нуруу болон Говь-Алтайн нурууны хоорондох Нууруудын хөндийд орших хамгийн том нуур юм. Энэхүү судалгааны зорилго нь Бөөнцагаан нуурын талбайн өөрчлөлтийг 1986-2022 он хүртэл тооцож, талбайн өөрчлөлтөд нөлөөлж буй хүчин зүйлсийг үнэлэх юм. Бөөнцагаан нуурын усан гадаргын талбайн өөрчлөлтийг Ландсат хиймэл дагуулын цуврал мэдээг ашиглан “Засварт нормчлогдсон ялгаврын усны өөрчлөлтийн индекс”-ийн тусламжтайгаар тооцоолж, нуурын ууршилтын олон жилийн динамикийг Мейерийн нуураас уурших ууршилтын томьёог ашиглан илрүүлсэн. Түүнчлэн хээрийн судалгааг 2022 оны зуны улиралд явуулж, нуурын эргийн хэмжилтийг 74 цэг дээр хийсэн. Нуурын усан гадаргын талбайн өөрчлөлтийн үнэмшлийг каппа коэффициентоор шалгасан. Тус судалгааны үр дүнд Бөөнцагаан нуурын талбай 1994-2000 онуудад хамгийн том усан гадаргатай байсан нь ажиглагдсан боловч сүүлийн 36 жилийн хугацаанд нуурын талбай 7.9%-иар багасаж, нуурын дундаж талбайн жилийн өөрчлөлтийн хэлбэлзэл 0.34% байсан. Түүнчлэн агаарын температур, салхины хамгийн их хурд болон Байдраг голын урсац нь тус нуурын талбайн өөрчлөлтөд нөлөөлж буй голлох хүчин зүйлүүд бөгөөд цаашид ч тус нуурын гадаргын талбайн хэмжээ буурах хандлагатай байна.

Published: March 2024

Estimation of aboveground biomass is important for sustainable forest management and climate change mitigation. Traditional methods for estimating aboveground biomass rely on data collected from field measurements, which is spatially limited and also very expensive. Over the last years, remotely sensed (RS) datasets have been widely used for forest biomass assessment. So, the main aim of this research is to estimate and then map the above ground biomass (AGB) of forested site using modern radar satellite data. The study has the following objectives: I. Estimate the biomass of forest land, II. Estimating AGB using vegetation indices and Sentinel-1 satellite data recorded in the C-band with 5.55 cm wavelength. III. Conduct a comparative study of principal component analysis and random forest methods. As a test site, the area around Khangal sum of Bulgan Province was selected. In the study, the random forest method showed good results, and for Level 1 GRD data R2=0.823, RMSE=0.116 t/ha, while for Level 1 SLC data R2=0.815, RMSE=0.105 t/ha. Overall, sthe reseach indicated that it is possible to determine the AGB of forests in the temperate zone of Mongolia using radar satellite data.

Published: March 2024

In recent years, digital remote sensing optical datasets and various indices calculated by using them have been intensively applied for green vegetation biomass evaluation and other thematic studies. The main goals of this study were to evaluate the vegetation biomass in the forest-steppe and steppe zones of Mongolia using the indices calculated from medium-resolution satellite data and map the biomass distribution. Indices were calculated from different visible, near, and mid-infrared bands of MODIS data acquired on August 21, 2016, and then classified and compared using machine learning methods such as random forest (RF), support vector machine (SVM), and partial least square regression (PLSR). Among the selected methods for biomass mapping in the forest-steppe and steppe areas, the RF method demonstrated the highest accuracy with a coefficient of determination (R2) of 0.889, and a root mean square error (RMSE) of 0.713 c/ha. The PLSR method had an R2 of 0.296 and an RMSE of 1.854 c/ha, while the SVM method showed the lowest accuracy with an R2 of 0.273 and an RMSE of 1.889 c/ha. Our finding indicates that the RF is a more applicable approach for assessing and mapping the vegetation biomass in the forest-steppe and steppe zones of Mongolia.

Published: March 2024

Since the launch of the European Space Agency’s Sentinel-1 radar and Sentinel-2 optical satellites, high-resolution multisource datasets have widely been used for land cover classification and other thematic research. The aim of this study was to segment 4 different indices derived from Sentinel-1 and 2 satellite datasets using multisolution and quadtree methods, classify the land cover of the selected area using an object-based classification method, and make a comparison. As a test site, the northwestern part of Khuvsgul Lake was selected, and integrated images acquired from Sentinel-1 and 2 satellites in June 2022 were analyzed. According to the results, the overall accuracy of the classification based on the quadtree segmentation was 99.71%, while the overall accuracy of the classification based on the multisolution segmentation was 98.80%. This finding indicates that using the quadtree method provides better results in determining the land cover types of the selected area.
