THE LOW MACH NUMBER LIMIT FOR ISENTROPIC COMPRESSIBLE NAVIER-STOKES EQUATIONS WITH A REVISED MAXWELL'S LAW

We investigate the low Mach number limit for the isentropic compressible NavierStokes equations with a revised Maxwell's law(with Galilean invariance) in R^(3). By applying the uniform estimates of the error system, it is proven that the solutions of the isentropic Navier-Stokes equations with a revised Maxwell's law converge to that of the incompressible Navier-Stokes equations as the Mach number tends to zero. Moreover, the convergence rates are also obtained.

ISO publishes revised standard for ground support equipment and relevant systems

Aerospace is always a pursuit of humans,not only out of desire for knowledge,but also out of persevering ambition.Ground support equipment(GSE)and relevant systems are of vital significance,which is fundamental to space system programs and projects.Though there are standards for ESG,the standards for ESG inspection and maintenance are necessary to perfect the whole process.

Revised Stratigraphy and Mineral Resources of Balochistan Basin, Pakistan: An Update

The Balochistan basin is located on the south western part of Balochistan Province and also Pakistan. Balochistan super basin is subdivided into northern Balochistan (Pishin basin or Kakar Kohorasan basin represented as back arc basin), central Balochistan (Chagai-Raskoh-Wazhdad Magmatic arc and Hamuns-Inter arc basin) and southern Balochistan (Makran Siahan basin) basins. Balochistan basin consists of Cretaceous to recent sediments, diverse igneous rocks and low grade metamorphics. Balochistan basin is a leading basin which consists of very significant mineral deposits especially copper and gold deposits. These mineral resources need to be developed for the development of areas, province and Pakistan. During previous half century a lot of geological work has been done in Balochistan basin. Here the revised stratigraphic set up and its mineral resources with an update are being presented.

Interpretation of the diagnosis and treatment plan of Corona Virus Disease 2019 (tentative fifth revised edition)

On February 8th,2020,National Health Commission of the People's Republic of China issued the Diagnosis and Treatment Plan of Corona Virus Disease 2019(Tentative Fifth Revised Edition).Since December 2019,Wuhan City,Hubei Province has successively discovered multiple cases of patients with Corona Virus Disease 2019(COVID-19).With the spread of the epidemic,other cases in China and abroad have also been found.Most of the currently reported cases have a history of residence or travel in Wuhan,but cases without that have already been found in some areas.As an acute respiratory infectious disease,COVID-19 has been classified into the Class B communicable diseases stipulated by the Law on the Prevention and Treatment of Infectious Diseases of the People's Republic of China,and managed as a Class A communicable diseases.

A revised jump-diffusion and rotation-diffusion model

Quasi-elastic neutron scattering(QENS) has many applications that are directly related to the development of highperformance functional materials and biological macromolecules, especially those containing some water. The analysis method of QENS spectra data is important to obtain parameters that can explain the structure of materials and the dynamics of water. In this paper, we present a revised jump-diffusion and rotation-diffusion model(rJRM) used for QENS spectra data analysis. By the rJRM, the QENS spectra from a pure magnesium-silicate-hydrate(MSH) sample are fitted well for the Q range from 0.3 ^(-1) to 1.9 ^(-1) and temperatures from 210 K up to 280 K. The fitted parameters can be divided into two kinds. The first kind describes the structure of the MSH sample, including the ratio of immobile water(or bound water) C and the confining radius of mobile water a_0. The second kind describes the dynamics of confined water in pores contained in the MSH sample, including the translational diffusion coefficient Dt, the average translational residence timeτ0, the rotational diffusion coefficient D_r, and the mean squared displacement(MSD) u^2. The r JRM is a new practical method suitable to fit QENS spectra from porous materials, where hydrogen atoms appear in both solid and liquid phases.

DECODING ALGORITHM BASED QN REVISED SYNDROME FOR THE BINARY (23,12,7) GOLAY CODE

A decoding algorithm based on revised syndromes to decode the binary (23,12,7) Golay code is presented. The algorithm strongly depends on the algebraic properties of the code. For the algorithm, the worst complexity is about 683 mod2 additions, which is less than that of the algorithms available for the code, the average complexity is approximately 319 mod2 additions, which is slightly more than that of Blaum’s algorithm for the code.

Revise and Statistical Analysis of the Alien Press Errors in History of Chinese Journalism by Ko Kung-chen

Since Ko Kung-chen published History of Chinese Journalism with Shanghai Commercial Press in 1927,this work had been published by different publishing houses and reprinted many times amounting to 18 editions.There are many historical narrative and fact errors of alien press in this work,and up to date these errors are not revised.This essay aims to revise the omitted errors of alien press in History of Chinese Journalism systematically besides those corrected by other works or essays,and carry on the statistical analysis of the errors to probe new approach for the study of alien periodicals and press in China.

The Revised Realization of Sapir:Whorf Hypothesis

There are a lot of arguments on Sapir-Whorf hypothesis in linguistics field,most of the scholars have given their own understandings toward this theory.It is easier to comment on a theory no matter what kind of theory it is,however,different views do not come from the same theory but different understandings of it,so writer think it is necessary to give a revised realization to the theory.

Aristolane‑type Sesquiterpenoids from Nardostachys chinensis and Revised Structure of Aristolanhydride

Four hitherto unknown aristolane-type sesquiterpenes,including one novel 8,9-secoaristolane,namely secoaristolenedioic acid(1),two aristolone derivatives,namely 1α,2β-dihydroxyaristolone(2),9-epidebilon(3),and one rare aristolane-chalcone hybrid,namely 3′-hydroxynardoaristolone A(4)were isolated from the ethanol extract of the roots and rhizomes of Nardostachys chinensis.Their structures were elucidated on the basis of extensive spectroscopic analysis.In addition,the structure of aristolanhydride,recently isolated from the same species,was corrected by reanalysis of the published NMR data.

Management of metal-on-metal hip implant patients: Who,when and how to revise?

The debate on how best to manage patients with metal-on-metal(MOM) hip implants continues. With over 1 million patients affected worldwide, the impact is far reaching. The majority of the aggressive failures of MOM hip implants have been dealt with by revision hip surgery, leaving patients with a much more indolent pattern of failure of devices that have been in situ for more than 10 years. The longer-term outcome for such patients remains unknown, and much debate exists on how best to manage these patients. Regulatory guidance is available but remains open to interpretation due to the lack of current evidence and long-term studies. Metal ion thresholds for concern have been suggested at 7 ppb for hip resurfacing arthroplasty and below this level for large diameter total hip arthroplasties. Soft tissue changes including pseudotumours and muscle atrophy have been shown to progress, but this is not consistent. New advanced imaging techniques are helping to diagnose complications with metal hips and the reasons for failure, however these are not widely available. This has led to some centres to tackle difficult cases through multidisciplinary collaboration, for both surgical management decisions and also follow-up decisions. We summarise current evidence and consider who is at risk, when revision should be undertaken and how patients should be managed.
