洛阳，风流何在 古韵苍凉——潞泽会馆里的雕刻艺术

清乾隆年间（公元一七四四年），在洛阳老城密密麻麻的青砖青瓦民房中，出现了一组规模宏伟的建筑群，它占地一万五千多平方米，面对洛河，气势非凡。该建筑群挺过了改朝换代的天翻地覆，经历了解放战争的枪林弹雨，闯过了九死一生的“文革”焚火，挣扎着苟活到了今天，成了洛阳屈指可数的还有几许原汁原味的建筑群。正国为如此，它成了洛阳市内“全国重点保护单位”。如今，该古建筑群被作为洛阳民俗博物馆，向世人展示中原大地清代古建筑的特色，也展示河洛地区多姿多彩的民俗文化。

要勇于突破和创新

曾听过这样一则故事，一位服装店老板收了两个徒弟。大徒弟聪明能干，师傅教的一点就通、一看就会，很快掌握了裁剪、缝纫等全套技术；小徒弟心灵手巧，但有点不安分，常常对服装设计提出一些奇思异想，弄得师傅哭笑不得。几年后两个徒弟都出师了，大徒弟自己开了个服装店，小徒弟则去了大城市打工，一直没有音讯。又过了若干年，大徒弟的手艺超过了师傅，成了小有名气的服装师傅，服装店生意也比较稳定。

Heating value of biomass and biomass pyrolysis products

Studies conducted on the heating value of various types of biomass components and their pyrolysis products such as char, liquids and gases are presented. Heating values of chars are comparable with those of lignite and coke; heating values of liquids are comparable with those of oxygenated fuels such as methanol and ethanol, which are much lower than those of petroleum fuels. Heating values of gases are comparable with those of producer gas or coal gas and are much lower than that of natural gas. It is also found that the heating values of products are functions of the initial composition of biomass; correlations are developed to express these. Also, correlations are developed which explain the influence of ash elements on heating values of the pyrolysis products and on percentage distribution of energy in the products.

Selection of glass-reinforced plastics materials for large marine structures

Some of the material investigations which are necessary before a glass-reinforced plastic (GRP) can be selected for use in large marine structures are described. The requirements of large-scale manufacture are as important as mechanical performance when the basic constituents of the laminate, the polyester resin and the glass reinforcements, are being selected. Various production problems which can arise, and the need for detailed quality control, are discussed. Other areas of investigation which are appropriate are the performance of joints and fasteners, and the influence of the glass reinforcement on the impact resistance of the laminate.     

Dynamics of large-scale fluctuations in native proteins. Analysis based on harmonic inter-residue potentials and random external noise

The fluctuations of residues of proteins about their equilibrium configurations are analyzed by the Langevin equation. Residue pairs that are covalently bonded and those that are within a given cutoff distance of each other are assumed to be connected by linear springs. The actions of the solvent and intramolecular interactions on each residue are treated as random noise. The correlations of fluctuations resulting from the solution of the Langevin equation are observed to be identical to those obtained by the Gaussian Network Model based on equilibrium statistical mechanics. The time-delayed correlations of fluctuations, and the response of the protein to a given frequency and to a window of frequencies are determined. The fluctuations of the residues resulting from a given fixed externally applied frequency are evaluated for different modes of the system. Synchronous and asynchronous components of correlations for different modes are formulated. The findings of the present paper are applied to the 241 residue protein S. marcescens endonuclease (1QL0).

Metal–Oxide Interactions on Copper-Segregated and Copper-Deposited TiO2 Rutile (001) Surfaces

Scanning tunneling microscopy and spectroscopy are used to study local electronic variations across a surface containing one monolayer of copper on TiO₂ rutile (001). The interactions that occur at the metal–oxide interface when the sources of the copper are segregation from the bulk and ultra-high-vacuum deposition are compared by characterizing the associated surface morphologies and electronic properties. The morphologies of these surfaces are similar in that the copper forms clusters; they are dissimilar in that copper features exist on two size scales on the segregated surface, whereas the deposited copper clusters are uniform in size and are aggregated. The electronic properties of the two surfaces also are found to differ: the copper-segregated surface is insulating, whereas the copper-deposited surface is conductive. The electronic properties are discussed in terms of the effects of surface-charge and ionic-charge concentration gradients.     

New classes of exact solutions to general nonlinear diffusion-kinetic equations

New classes of exact solutions of nonlinear equations and systems of equations that are encountered in the mass and heat transfer theory of reacting media and mathematical biology are described. General equations and systems of equations where the rates of chemical reactions depend on one or several arbitrary functions are the focus of attention. Solutions with functional arbitrariness are found (they are expressed through the solutions of a linear heat transfer equation and the solutions of nonlinear systems of ordinary differential equations); solutions with generalized separation of variables and other solutions are described. The transfer coefficients and the kinetics of chemical reactions are considered as functions of temperature (concentration).     

Donors for Organic Metals: Molecular Aspects

Physicochemical issues are discussed which are relevant to chemists interested in the synthesis of unknown compounds to serve as precursors to organic metals. Molecular topics are emphasized, physical and structural concepts which motivate synthetic activity in chalogen chemistry are presented, and new results in selenium and tellurium systems are summarized. Two model representations for donor molecular structures based on polyenes and polyacenes are presented and known examples are discussed. Quantitative correlations between gas phase vertical ionization potential and solution electrochemical redox potential are examined using donors of interest for organic metals as data. Limitations of such correlations and consequences of these shortcomings are given. Finally, possible future directions for several of these topics are posed.
