Antimicrobial activity of electrolyzed saline solutions

Electrolysis of solutions containing certain electrolytes, through the use of novel electrodes, produces significant levels of ozone, oxygen, and chlorine at the anode. The process works at ordinary temperatures, and with dilute solutions. These solutions, after electrolysis, can be much more effective, by a factor of several hundred, against microorganisms than solutions containing comparable hypochlorite solutions.     

Exact and approximate solutions for the flexural buckling of columns with oblique rotational end restraints

This paper is concerned with the elastic flexural buckling of doubly symmetric columns with oblique restraints under concentric loading. Oblique restraints cause coupling between the principal axis deflections and rotations, and the flexural buckling mode involves simultaneous bending about both principal axes.The paper discusses the nature of oblique restraints, and presents exact and approximate solutions for the buckling loads of columns with rigid or elastic restraints against rotations at the ends. The exact solutions are obtained by solving the governing differential equations and boundary conditions, while the approximate solutions are based on energy solutions with assumed buckling displacements. The approximate solutions are sufficiently simple that they can be used in design, and are shown to be within 1% of the exact solutions.     

Detoxification of phenolic solutions with horseradish peroxidase and hydrogen peroxide

Phenolic solutions were treated with hydrogen peroxide and horseradish peroxidase (HRP) resulting in more than 95% removal of phenols within 3 h. Toxic compounds were formed during the treatment of aqueous solutions of phenol, 2-chlorophenol, 4-chlorophenol, 2,4-dichlorophenol and 2-methylphenol. However, the toxicities of HRP-treated solutions decreased within 21 h after the completion of the enzymatic reaction, except in the case of 2-methylphenol. The process of detoxification was significantly accelerated upon the addition of hydrogen peroxide to the dephenolized solutions. Solutions that were treated in the presence of chitosan exhibited lower toxicities than solutions treated in its absence if they were allowed to incubate for an extended period of time. Treatment in the presence of polyethylene glycol resulted in significantly higher toxicities. The toxicity of treated solutions was dependent on the addition mode of HRP and hydrogen peroxide. Treated solutions were also completely detoxified following illumination with UV light.

Toxicity to Daphnia of the end products of wet oxidation of phenol and substituted phenols

The process of wet oxidation breaks down organic substances in aqueous solution at elevated temperatures and pressures. Experimental wet oxidations were carried out on pure solutions of phenol, 2-chlorophenol and 4-nitrophenol. After 1-h wet oxidation, final concentrations of these compounds averaged 3% of their concentrations in the starting solutions. The toxicities of the starting compounds and the residual toxicity of the end-product solutions were measured with 48-h acute toxicity tests using Daphnia magna. The solutions of end products were all less toxic than the starting solutions by factors ranging from 10 to 120. However, the end-product solutions were somewhat more toxic than would be predicted from the known concentration of initial compound remaining in the solution of end products.

Yue’s solution of classical elasticity in n-layered solids: Part 1, mathematical formulation

This paper presents the exact and complete fundamental singular solutions for the boundary value problem of a n-layered elastic solid of either transverse isotropy or isotropy subject to body force vector at the interior of the solid. The layer number n is an arbitrary nonnegative integer. The mathematical theory of linear elasticity is one of the most classical field theories in mechanics and physics. It was developed and established by many well-known scientists and mathematicians over 200 years from 1638 to 1838. For more than 150 years from 1838 to present, one of the remaining key tasks in classical elasticity has been the mathematical derivation and formulation of exact solutions for various boundary value problems of interesting in science and engineering. However, exact solutions and/or fundamental singular solutions in closed form are still very limited in literature. The boundary-value problems of classical elasticity in n-layered and graded solids are also one of the classical problems challenging many researchers. Since 1984, the author has analytically and rigorously examined the solutions of such classical problems using the classical mathematical tools such as Fourier integral transforms. In particular, he has derived the exact and complete fundamental singular solutions for elasticity of either isotropic or transversely isotropic layered solids subject to concentrated loadings. The solutions in n-layered or graded solids can be calculated with any controlled accuracy in association with classical numerical integration techniques. Findings of this solution formulation are further used in the companion paper for mathematical verification of the solutions and further applications for exact and complete solutions of other problems in elasticity, elastodynamics, poroelasticty and thermoelasticity. The mathematical formulations and solutions have been named by other researchers as Yue’s approach, Yue’s treatment, Yue’s method and Yue’s solution.

Can integrated solutions business models work in construction?

It has recently been suggested that the future of the construction industry lies in adopting a new business model based on the concept of integrated solutions. Integrated solutions are combinations of products and services that address a customer's unique requirements throughout the life cycle, from development and design to systems integration, operations and decommissioning. Research on integrated solutions in other capital goods sectors has shown suppliers have had to create new business models, including developing new approaches to adding value, and building up new capabilities - especially in systems integration. The paper presents some preliminary empirical findings about construction industry perceptions of value, systems integration and integrated solutions that suggest the concept of built environment solutions provision is still at an early stage in its development and that the best opportunity for its introduction is in the context of private finance initiatives in the public sector or large clients who require repeatable solutions in the private sector.     

水岩化学作用对砂岩力学特性影响的试验研究

为研究水岩化学作用对砂岩力学特性的影响,将桃源水电站的红砂岩加工成标准圆柱形试样,对其进行不同化学溶液作用下的腐蚀试验,获得红砂岩化学腐蚀过程中相对质量变化规律,同时测量记录各化学溶液pH值。利用岩石三轴测试系统对各种化学溶液浸泡后的红砂岩进行三轴压缩试验,探讨不同的化学溶液对红砂岩力学特性的腐蚀效应,获得水化学溶液对红砂岩强度和变形特性的影响规律。结果表明,试样质量的变化和化学溶液性质有关,试样相对质量变化存在明显差异。pH=13的化学溶液pH值随时间的增长有小幅度下降,其余化学溶液pH值随时间增长均趋于弱碱性(pH≈7.9)。根据溶液pH值的变化、试样相对质量的变化,分析化学溶液对岩石的腐蚀程度。三轴压缩试验结果表明,不同化学溶液对红砂岩力学性质的影响不同。离子成分及pH值均对红砂岩力学特性产生较大影响,各种化学溶液腐蚀后岩石的峰值强度、残余强度、弹性模量均有不同程度的下降。室内试验的结果可为构建红砂岩化学腐蚀条件下本构模型提供重要的试验资料。
