Significance
Ketogenic diet is an effective treatment for nonalcoholic fatty liver disease (NAFLD). Here, we present evidence that hepatic mitochondrial fluxes and redox state are markedly altered during ketogenic diet-induced reversal of NAFLD in humans. Ketogenic diet for 6 d markedly decreased liver fat content and hepatic insulin resistance. These changes were associated with increased net hydrolysis of liver triglycerides and decreased endogenous glucose production and serum insulin concentrations. Partitioning of fatty acids toward ketogenesis increased, which was associated with increased hepatic mitochondrial redox state and decreased hepatic citrate synthase flux. These data demonstrate heretofore undescribed adaptations underlying the reversal of NAFLD by ketogenic diet and highlight hepatic mitochondrial fluxes and redox state as potential treatment targets in NAFLD.
Little cutie one piece

AbstractThis study investigates emerging usages in Chinese cyberspace of the numeral classifierméithat violate syntactic and semantic conventions of canonical grammar of modern Chinese. We treat these usages as constructional variants of the canonical classifier construction and show how they afford users of Weibo a device of social indexicality in the sense of Silverstein (1976,1985,2003) and Eckert (2000,2003,2008). We argue that the constructional variants facilitate the creation of a cute, chic, playful, humorous, and youthful online style and that its popularity draws on multiple indexical resources including contrast to canonical grammar, contemporary language contact with Japanese, influence of the cuteness culture and its commodification, and consumerism in the digital economy. This study contributes to research on the linguistic construction of identity and style, linguistic creativity in the new media and digital culture, and usage-based constructionist approaches to language.
Social class, language attitudes, and language use
Authors: Liu Binmei 
Published: March 2020

AbstractFew previous studies have examined the impact of social class on language attitudes and language use in mainland China. A total of 215 questionnaires were collected from a university in China for this study. The participants were classified into four social classes: upper middle class, middle middle class, lower middle class, and lower class. Then an individual interview was conducted with 10 students. Findings show that the students from the upper middle class had significantly lower attitudes toward local dialects and they had the lowest percentage of current use of dialect at home. The study adds evidence to findings of previous studies that local dialects might face certain danger of maintenance. It also shows that this change would start from people from the upper middle class. The study also points out a possible future tendency that social class privilege will play a more significant role in English learning and education.

Published: March 2020

Abstract
A major study has been released on the emergence in East Asia of the logographic, or logo-syllabic, writing systems inherited from Chinese writing, attending primarily to the adaptations and innovations implemented in Korea, Vietnam, Japan and by speakers of the Tai languages of Southern China and Northern Vietnam. It contributes to our understanding of the fundamental mechanisms, of how speakers of different languages transformed the character script. The book points to overarching research problems concerning the relationship between language and writing, how aspects of this relationship are based on universal principles of learning exemplified in bilingual literacy. The research questions presented by the author will ultimately help us better understand literacy learning and the nature of reading and writing ability in general.
Entre influence et coïncidence: La réminiscence du grec dans l’arabe
Authors: Sartori Manuel 
Published: March 2020

Résumé
Deux points de vue s’opposent concernant les débuts de la grammaire arabe: la grammaire arabe serait apparue comme une
discipline autonome ou aurait été en partie influencée par des modèles grecs (peut-être par le biais de traductions syriaques). En lien avec
ce débat, il semble particulièrement instructif d’étudier la catégorie de ʿaṭf bayān. Selon Rafael Talmon, il s’agit d’une
‘invention’ de Sībawayhi (m.180/796?) basée sur la distinction entre ṣifa (‘adjectif’) et un modificateur qui n’est pas un
adjectif mais assure une fonction adjectivale (ʿaṭf bayān). L’article tente de montrer qu’un contraste similaire peut être
trouvé dans des sources grecques (et latines) antérieures sous la forme d’une distinction entre epitheton et
epexegesis. En prenant en compte la connaissance hellénistique chez les Arabes avant et à l’époque de Sībawayhi, il est
alors possible de soutenir que l’auteur du Kitāb, faute de terminologie appropriée, a emprunté, directement ou non, la
distinction aux sources grecques. Cependant, s’il ne s’agit évidemment pas d’une pure coïncidence, l’emprunt qui a donné naissance à la
catégorie de ʿaṭf al-bayān ne doit pas être interprété comme une simple influence. Il serait peut-être préférable de le
concevoir en termes de réminiscence: la mémoire, par voie diffuse, des connaissances grecques dans la nouvelle érudition grammaticale
arabe.
Electrostatic responses of anisotropic dielectric films
Authors: Deng Hai-Yao 
Published: March 2020

Abstract
We study the electrostatic responses (i.e. retardation effects due to the propagation of electromagnetic waves are ignored) of a linear homogeneous and anisotropic (LHA) dielectric film to an arbitrary external electrostatic potential. A set of algebraic equations has been established to calculate the polarisation charges induced in the film. In our derivation, the idea is exploited that a physical boundary can be looked upon as a region of rapid variation in polarisation rather than a simple geometric separation. With this no boundary conditions are needed in solving the relevant electrostatics problem. Our approach makes it clear that the responses consist of two contributions, one arising from the very presence of surfaces while the other existing even in an infinite medium. In light of the results, we discuss graphene plasma waves under the influence of a LHA dielectric film such as a few-layer hexagonal boron nitride. It is found that the dispersion of these waves is strongly affected by the anisotropy at wavelengths comparable to the film thickness.

Authors: Alam K , Umer J , Iqbal M , Hasan A 
Published: March 2020

Abstract
Biological hydrogels are widely used as extracellular environment for encapsulating and growing cells. Mechanical properties of hydrogels can influence cell function, mechanotransduction and cellular behavior such as growth, migration, adhesion, differentiation and morphology. Microenvironmental modulus of hydrogels dictates cell behavior and growth. The main purpose of the current study was to determine elastic modulus of two well-known hydrogels (Agarose and Gelatin Methacryloyl) using Atomic Force Microscope (AFM). The elastic modulus was calculated from force-deflection curve obtained by indenting an indenter in the direction normal to the plane of the gel surface. The elastic moduli of the prescribed gels were found to be strongly influenced by the level of concentration in the gel. Elastic modulus of 1% agarose and 2% agarose was found comparable with 10% GelMA and 20% GelMA, respectively. Results obtained from indentation experiments and those published in the literature revealed that AFM can be successfully and confidently used to determine elastic response of hydrogels in the solid state.
Effect of Heat Treatment Temperature and Time on Preparation of Porous Walled Hollow Glass Microspheres (PWHGMs)

Published: March 2020

Abstract
The development of hollow glass microspheres (HGMs) with porous walls provides a unique system in which filling agents can be incorporated into the porous walled hollow glass microspheres (PWHGMs). Applications of these have been increased due to the many proposed uses for such a material. They are widely used in various fields of science and technology because of their unique properties, such as catalyst supports, photo catalysts, sorbents, gas sensors, molecular sieves, drug and bioactive delivery systems as well as chemical and biological indicators, etc. PWHGMs with their interior hollow volume and porous walls offer greater storage capacity and pathways for retaining and releasing of stored material. PWHGMs as additives can be used to increase porosity in the electrodes for more electrolyte storage in lead acid batteries and enhance the energy performance of the battery. Further, PWHGMs have potential applications in sensor materials, fuel cells, solar cell, chromatograph column fillers and as micro reactors to encapsulate Pd for catalytic hydrodechlorination of chlorophenols in water. In this research, efforts have been made to prepare PWHGMs from readily available borosilicate glass frits in the laboratory using flame spheroidisation method. The effect of heat treatment temperature and time on preparation of porous walled hollow glass microspheres was investigated. Hollow glass microspheres with wall thickness of 0.5–2 μm were fabricated from borosilicate glass frits in air-acetylene flame. The prepared microspheres were heat-treated and acid leached to produce porous walled hollow glass microspheres. According to results, suggest that heat treatment times used in this research are not as effective as the heat treatment temperatures in changing the porosity (or phase separation) in HGMs and the resulting PWHGMs.
A Review on Property Reforms for Fiber Matrix Composites through Various Surface Treatment of Fibers
Authors: Basak Reshmi , Gohil Piyush P. , Dey Sudip , Pandey Krishna Murari 
Published: March 2020

Abstract
The primary factor that defines the final performance of any composite material is the fiber-matrix interface. Hence, efficient amount of adhesion is needed for full-fledged performance of composite materials. When fibers are used without surface modification, they tend to produce composites with low strength. This in turn leads to weak adhesion and poor bonding between the fiber and matrix. Hence, there is a massive apprehension to alter the surface of fibers through various procedures, in order to overcome their intrinsic downsides and effectively employ these materials in countless applications. This paper deals with a review of prevailing research studies fixated on the surface treatment of fibers.
Comparative studies on the corrosion behavior of some Zr-based amorphous alloys having different compositions in nitric acid medium
Authors: Sharma Poonam , Dhawan Anil , Sharma S. K. 
Published: March 2020

Abstract
The corrosion studies were performed on different composition of Zr-based bulk amorphous ribbon alloys such as Zr55Cu30Ni5Al10, Zr60Nb2Cu20Ni8Al10, Zr59Nb3Cu20Ni8Al10, Zr57Nb5Cu20Ni8Al10 and Zr60Pd5Cu15Ni10Al10 alloys at room temperature. The amorphous nature of all the above mentioned alloys was confirmed by X-ray diffraction (XRD). The corrosion behavior was investigated using potentiodynamic polarization and weight loss analysis methods at room temperature. Surface morphology of these corroded samples were investigated by optical microscopy and scanning electron microscopy (SEM). The results of the investigations revealed the fact that Nb containing Zr-based bulk amorphous alloys shows better corrosion resistance among all the investigated alloys due to the presence of Nb2O5. The presence of Nb2O5 on the surface of Nb containing Zr-based bulk amorphous alloy after immersion in HNO3 medium was confirmed by X-ray photoelectron spectroscopy (XPS) techniques.

Published: March 2020

Abstract
Produced water (PW) is the abundant by-product of oil and gas industries. It contains several organic pollutants and needs proper treatment before its discharge. This study investigated the effectiveness of Ferrate (VI) (Fe6+) oxidation for remediation of the organic compounds produced water. A series of batch experiments were performed by ferrate oxidation method. A glass beaker of 1000 ml as reactor covered with aluminum foil was used to protect from sunlight. Produced water sample of 300 ml and a pre-decided amount of Fe6+ was added to initiate the oxidation process. All experiments were performed at constant magnetic stirrer speed of 200 rpm at room temperature. The Fe6+ dosage of 1-25 mg/l, pH 1-7, and contact time 5-90 minutes were used to determine the effectiveness of Fe6+ for organic compounds degradation. The COD removal was increased with the increase in Fe6+ dosage and contact time. The maximum COD removal was achieved with Fe6+ dosage up to 15 mg/l; further any increase in Fe6+ dosage decreased the COD removal. The same trend was observed for pH, COD removal was increased until pH 5 beyond that COD removal was decreased. Maximum 55% of COD removal was attained under optimum conditions such as pH, Fe6+ dosage, and contact time were 5, 15mg/l and 50mins respectively. The results indicate that Ferrate (VI) oxidation is a promising method for the degradation of organic compounds in produced water.

Published: March 2020

Abstract
This paper proposes a spherical gear pair with three degrees of freedom based on meshing transmission principle. The kinematic meshing relationship between the spherical gear pair is illustrated with its pitch spheres and pitch cones. This determines that the spherical gear surface is completed with two tooth surfaces of ring-involute spherical gear and a semi-spherical bevel gear. Mathematical models and numerical results of the two tooth surfaces are presented for obtaining geometry model of the spherical gear pair with the CAD three-dimensional molding technique. This study provides the basis for future studies to design and analyze a novel spherical gear.

Published: March 2020

AbstractThis paper reviews the traditional thermal control implementation of satellite pipe in AIT process. As the thermistors and heating devices are too small compared to the satellite 3D model, the 3D design input is inconvenient to use. In order to improve efficiency and quality of thermal control implementation of satellite pipe, a system based on AR technology is designed. With the help of the system, the code and specification of the thermal control components are clear at a glance, so an ordinary operator can verify the polarity correctness of the thermal control implementation and the efficiency can be doubled.
Influence of structural parameters of venturi on internal flow field changes
Authors: Lv Chuanmao , Wang Puhao , Zhang Xiaoguang , Lv Haifeng 
Published: March 2020

Abstract
The influence of the inlet angle and the outlet angle of the venturi on the fluid flow state in the tube was studied. The control variable method was used to simulate the flow of the fluid inside the venturi by COMSOL software. The results show that when the inlet angle changes from 10.3° to 55°, the fluid flow velocity at the throat of the universal venturi is 19.5m/s, and the pressure varies from 1121.1Pa. When the outlet angle is changed from 10.3° to 55°, the fluid flow velocity inside the venturi varies by 0.8 m/s, and the pressure varies from 6060.2 Pa. Therefore, it can be concluded that changing the angle of the outlet has a greater influence on the negative pressure at the throat of the venturi. The change in the negative pressure caused by changing the inlet angle is weak, but the flow rate changes greatly.
