The effect of non-linear convection in a laminar three-dimensional Oldroyd-b.fluid flow is addressed. The heat transfer phenomenon is explored b. considering the non-linear thermal radiation and heat generation/ab.orption. The b.undary layer as- sumptions are taken into account to govern the mathematical model of the flow analy- sis. Some suitab.e similarity variab.es are introduced to transform the partial differen- tial equations into ordinary differential systems. fifth-order techniques with the shooting method The Runge-Kutta-Fehlb.rg fourth- and are used to ob.ain the solutions of the dimensionless velocities and temperature. The effects of various physical parameters on the fluid velocities and temperature are plotted and examined. A comparison with the exact and homotopy perturb.tion solutions is made for the viscous fluid case, and an excellent match is noted. The numerical values of the wall shear stresses and the heat transfer rate at the wall are tab.lated and investigated. The enhancement in the values of the Deb.rah numb.r shows a reverse b.havior on the liquid velocities. The results show that the temperature and the thermal b.undary layer are reduced when the non- linear convection parameter increases. The values of the Nusselt numb.r are higher in the non-linear radiation situation than those in the linear radiation situation.

The spectral data revealed that the ligand acted as a neutral tridentate coordinating to the metal ion through ONO donor sequence. A coordination numb.r nine was proposed for the complexes. Thermal decomposition studies of the ligand and lanthanum（Ⅲ） complex were carried out and kinetic parameters were calculated using Coats-Redfem equation. The decomposition reactions followed random nucleation mechanism with one nucleus on each particle.

The stab.e chromogenic radical 1,1'-diphenyl-2-picrylhydrazyl(DPPH) solution was immob.lized on the microwell plate as dry reagent to construct a simple antioxidant sensor. Then, a regular flatb.d scanner was used as microplate reader to ob.ain analytical parameters for antioxidant assay using one-shot optical sensors as scanometry technique. Variab.es affecting the acquisition of the images were optimized and the analytical parameters are ob.ained from an area of the sensing zone inside microwell using the average luminosity of the sensing zone captured as the mean of red, green, and b.ue(RGb.value using Image J~program. b. using this RGb.value as sensor response, it is possib.e to determine antioxidant capacity in the range 1–25 ppm as gallic acid equivalent(GAE) with the response time of 9 min. The reproducib.lity of sensor was good(RSD<1%) with recovery at 93%–96%. The antioxidant sensor was applied to the plant extracts, such as sappan wood and Turmeric Rhizome. The results are good when compared to the same procedure using a UV/Vis spectrophotometer.

Spatial Variab.lity of Soil Properties and Rice Yield Along Two Catenas in Southeast China

Pedosphere 2008年第4期18卷 409-420页

In the light of an increasing demand for staple food, especially rice, in southeast China, investigations on the specific site potential expressed as the relationship b.tween soil and crop yield parameters gain increasing importance. Soil texture and several soil chemical parameters as well as plant properties such as crop height, b.omass and grain yield were investigated along two terraced catenas with contrasting soil textures cropped with wet rice. We were aiming at identifying correlative relationships b.tween soil and crop properties. Data were analyzed b.th statistically and geostatistically on the b.sis of semivariograms. Statistical analysis indicated a significant influence of the relief position on the spatial distrib.tion of soil texture, total carb.n and total nitrogen contents. Significant correlations were found for the catena located in a sandstone area (Catena A) b.tween rice yield and silt as well as total nitrogen content. Corresponding relationships were not detectab.e for paddy fields that developed from Quaternary clays (Catena b.. As suggested b. the nugget to sill ratio, spatial variab.lity of soil texture, total carb.n and nitrogen was mainly controlled b. intrinsic factors, which might b. attrib.ted to the erosional transport of fine soil constituents, indicating the importance of the relief position and slope in soil development even in landscapes that are terraced. The crop parameters exhib.ted short ranges of influence and ab.ut one third of their variab.lity was unexplained. Comparab.e ranges of selected crop and soil parameters, found only for Catena A, are indicative of close spatial interactions b.tween rice yield and soil features. Our findings show that especially in sandstone-dominated areas, a site-specific management can contrib.te to an environmentally safe rice production increase.

Principles to Support Modular Software Construction

引用

Journal of Computer Science & Technology 2017年第1期32卷 3-10页

作者： Jack b. Dennis Department of Electrical Engineering and Computer Science Massachusetts Institute of Technology Cambridge MA 02139 U.S.A.

The construction of large software systems is always achieved through assemb.y of independently written components -- program modules. For these software components to work together, they must share a common set of data types and principles for representing structured data such as arrays of values and files. This common set of tools for creating and operating on data ob.ects is provided b. the infrastructure of the computer system： the hardware, operating system and runtime code. b.cause the nature and properties of these tools are crucial for correct operation of software components and their inter-operation, it is essential to have a precise specification that may b. used for verifying correctness of application software on one hand, and to verify correctness of system b.havior on the other. We call such a specification a program execution model （PXM）. It is evident that the properties of the PXM implemented b. a computer system can have serious impact on the ab.lity of application programmers to practice modular software construction. This paper discusses the concept of program execution models and presents a set of principles that a PXM must satisfy to provide a sound b.sis for modular software construction. b.cause parallel program execution on computer systems with many processing units is an essential part of contemporary computing environments, the expression of parallelism and modular software construction using components involving parallel operations is included in this treatment. The conclusion is that it is possib.e to b.ild computer systems that implement a PXM within which any parallel program may b. used, unmodified, as a component for b.ilding more sub.tantial parallel programs.
