Differential scanning calorimetry (DSC) is one of the few techniques that allow direct determination of enthalpy values for binding reactions and conformational transitions in biomolecules. It provides the thermodynamics information of the biomolecules which consists of Gibbs free energy, enthalpy and entropy in a straightforward manner that enables deep understanding of the structure function relationship in biomolecules such as the folding/unfolding of protein and DNA, and ligand bindings. This review provides an up to date overview of the applications of DSC in biomolecular study such as the bovine serum albumin denaturation study, the relationship between the melting point of lysozyme and the scanning rate. We also introduce the recent advances of the development of micro-electro-mechanic-system (MEMS) based DSCs.

DX桩由于承力盘的存在,改变了桩的荷载传递机理,在提高承载力的同时,沉降变形也显著减小。在桩的现场试验基础上,分析了DX桩与等截面桩的桩顶荷载的分配特性,进而依据Mindlin解和Geddes解求解桩端土的附加应力,编制了相应的程序,计算结果表明在同样的荷载条件下,DX桩的沉降是等截面桩的0.55~0.80倍,并对承力盘的变化引起的DX桩的沉降变化进行了分析。

20世纪90年代,中国掀起了一场关于21世纪社会主义中国城市发展模式的大讨论。钱学森教授提出的山水城市概念是把中国传统文化中的山水诗词、山水画和中国古典园林与现代城市建设结合起来。山水城市的核心思想是,兼顾城市生态和历史文化,兼顾现代科技和环境美学;它考虑未来城市生产、生活发展的需要;它是为中国老百姓享受的生活、工作环境。21世纪是城市的世纪,主要是发展中国家的城市化。中国已经开始进入城市化高速发展的时期,世界关注中国城市化发展的道路。这是山水城市讨论的时代背景。中华民族对山水有特殊的感情,山水意识几乎融入中华民族的遗传基因,山水文化的特色之一是综合艺术,这是山水城市的文化背景。

The kinematic assumptions upon which the Euler-Bernoulli beam theory is founded allow it to be extended to more advanced analysis. Simple superposition allows for three-dimensional transverse loading. Using alternative constitutive equations can allow for viscoelastic or plastic beam deformation. Euler-Bernoulli beam theory can also be extended to the analysis of curved beams, beam buckling, composite beams and geometrically nonlinear beam deflection. In this study, solving the nonlinear differential equation governing the calculation of the large rotation deviation of the beam (or column) has been discussed. Previously to calculate the rotational deviation of the beam, the assumption is made that the angular deviation of the beam is small. By considering the small slope in the linearization of the governing differential equation, the solving is easy. The result of this simplification in some cases will lead to an excessive error. In this paper nonlinear differential equations governing on this system are solved analytically by Akbari-Ganji’s method (AGM). Moreover, in AGM by solving a set of algebraic equations, complicated nonlinear equations can easily be solved and without any mathematical operations such as integration solving. The solution of the problem can be obtained very simply and easily. Furthermore, to enhance the accuracy of the results, the Taylor expansion is not needed in most cases via AGM manner. Also, comparisons are made between AGM and numerical method (Runge-Kutta 4th). The results reveal that this method is very effective and simple, and can be applied for other nonlinear problems.
