We have developed a 2D analytical model for the sing.e g.te AllnSb/lnSb HEMT device by solving.the Poisson equation using.the parabolic approximation method. The developed model analyses the device perfomance by calculating.the parameters such as surface potential, electric field distribution and drain current. The hig. mobility of the AlInSb/InSb quantum makes this HEMT ideal for hig. frequency, hig. power applications. The working.of the sing.e g.te AllnSb/InSb HEMT device is studied by considering.the variation of g.te source voltag., drain source voltag., and channel leng.h under the g.te reg.on and temperature. The carrier transport efficiency is improved by uniform electric field along.the channel and the peak values near the source and drain reg.ons. The results from the analytical model are compared with that of numerical simulations （TCAD） and a g.od ag.eement between them is achieved.

The mesquite pods have a hig. nutritional value, being.a rich source of sug.rs, proteins, minerals and fibers that can be used as a raw material for the development of a number of food products and technolog.cal innovations. The objective of this work was to study the drying.kinetics of mesquite pods in a thin layer, 20 mm leng.h and determine the effective diffusion coefficient by adjusting.mathematical models that were based on heat transfer and mass fundamentals. For the experiments, we used mature mesquite, with 20% water content (b.u). Drying.experiments were performed using.temperatures of 50°C, 60°C, 70°C and 80°C with drying.air speed of 2 m•s-1. It was used a convective dryer with fixed bed and upflow air. Mathematical models of Fick, Pag., Cavalcanti-Mata, Two Exponential Terms and Henderson & Pabis were used to adjust the experimental data. To calculate the effective diffusivity, flat plate g.ometry with sample thickness of 6.5 mm was used. Based on the results obtained, it was concluded that the loss of water from mesquite occurred during.the drying.period in decreasing.rate;and with increasing.drying.temperature, total process time was reduced. The diffusion coefficient increased by increasing.drying.temperature. Mathematical models including.theoretical (Fick), semi-theoretical (Pag. and Cavalcanti-Mata) and empirical (Two Exponential Terms) models satisfactorily explain the experimental data of drying.mesquite.

Chinese Medical Journal 1932年第3期46卷 277-284页

作者： WM. g. LENNOX

Information was received from 211 Chinese physicians, 81 per cent of whom were married, the averag. ag. at marriag. being.24.7 years. Among.married physicians there were 3.46 living.births per family, or one birth for 3.26 married years. In comparison with poor Chinese, or with foreig.ers living.in China this is a hig. rate of birth. Infant death rates of 48 per 1,000 were low. In this g.oup a hig. standard of living.and medical knowledg. apparently have been ac- companied by hig. birth rates and low deaths. The relationship to the problem of population is discussed.

Inflammatory bowel disease (IBD) affects a part of the young.population and has a strong.impact upon quality of life. The underlying.etiolog. is not known, and the existing.treatments are not curative. Furthermore, a sig.ificant percentag. of patients are refractory to therapy. In recent years there have been g.eat advances in our knowledg. of stem cells and their therapeutic applications. In this context, autolog.us hematopoietic stem cell transplantation (HSCT) has been used in application to severe refractory Crohn’s disease (CD), with encourag.ng.results. Allog.nic HSCT would correct the g.netic defects of the immune system, but is currently not accepted for the treatment of IBD because of its considerable risks. Mesenchymal stem cells (MSCs) have immune reg.latory and reg.nerative properties, and low immunog.nicity (both autolog.us and allog.nic MSCs). Based on these properties, MSCs have been used via the systemic route in IBD with promising.results, thoug. it is still too soon to draw firm conclusions. Their local administration in perianal CD is the field where most prog.ess has been made in recent years, with encourag.ng.results. The next few years will be decisive for defining.the role of such therapy in the manag.ment of IBD.
