Industrially produced sodium water glasses were dried in climates with controlled temperature and humidity to transparent amorphous water containing sodium silicate materials. The water glasses had molar SiO2:Na2O ratios of 2.2, 3.3 and 3.9 and were dried up to 84 days at temperatures between 40°C and 95°C and water vapour pressures between 5 and 40 kPa. The materials approached final water concentrations which are equilibrium values and are controlled by the water vapour pressure of the atmosphere and the microstructure of the solids. The microstructure of the dried water glasses was characterized by atomic force microscopy. It has a nanosized substructure built up by the silicate colloids of the educts but deformed by capillary forces. In the final drying equilibrium, the water vapour pressure of the atmosphere in the drying cabinet is equal to the reduced vapour pressure of the capillary system built up by the silicate colloids. Their size scale can be explained by the deformation of colloidal aggregates due to capillary forces.

In order to help companies to improve their competetiveness, it is important to develop new design methodologies. In this framework, a Functional And Robust Design (FARD) methodology dedicated to routine design of “highly productive” modular product ranges is proposed including principles of functional analysis, Design For Assembly (DFA), and techniques of modelling and simulation for ergonomics consideration. This paper focuses on the application of this original method applied to mechanical vibration and ergonomics problems of a scraper. Including biomechanical aspect in the design methodology, it is possible to identify the impact of a vibration tool on its users using numerical models of the tool coupled to a finite element model of the human hand. This method can proactively warn very early, in the design process, the risks of causing musculoskeletal disorders and facilitate an optimization of the mechanical tool. This study is a first step in a context of human-centered design.

The study by the author of magnetic scattering neutrons in the structures of ferrimagnets, as well as his experiments with the separation of magnetic charges in dipole pairs ±g in magnetic field, showed that fundamental magnetic particles (magnetic charges) are real structural components of atoms and substance. It is the magnetic poles, and not the moving electric charges are the direct sources of all magnetic fields and magnetic manifestations in Nature. Basic reasons of ignoring the magnetic fundamental particles by world physical theory, for almost 150 years, are the ultra-harsh confinement of these particles in substance which radically is different from the confinement electrons, as well as the vicious concept of the electric magnetism Maxwell. Rotating magnetic dipoles in conductors which are untwisted by electric current, are direct sources of the vortex magnetic field rotH. One should also expect the formation of a vortex electric field rotE forming by rotating electric dipoles which are untwisted by the current of magnetic charges. This article provides an experimental answer to the question: what field is formed around a conductor if joint direct currents of electric Je and magnetic Jg charges are passed through it? The author’s experiments have shown that in this case the vortex electromagnetic current is realized which manifests itself as the vortex electromagnetic (gravitational) field. It is possible to implement such a process, according to the results of the author’s research, exclusively in superconductors. The vector character of the gravitational field is in many respects similar to the vortex magnetic field which makes it possible to introduce such it states as paragravitation and ferrogravitation into representations. To create joint currents of electric and magnetic charges, the autho

目的:探讨下方玻璃体腔注射比上方注射出现注射后眼内炎的几率是否更高。下方小梁切除术滤过泡眼内炎的发病率高于上方小梁切除术滤过泡,有可能是因为细菌聚集在下方的泪湖。方法:经过广泛实践过的眼内炎病例数据库验证,发现在2a的研究期间内,有5例眼内炎病例。同时,为了评估注射部位对发病率的影响,对治疗过的909例1 121眼共计8672次注射进行了回顾性调查。结果:5眼出现感染性眼内炎,80%的眼内炎病例均是下方注射,尽管所选病例中84.6%是位于上方注射。与感染有关的下方注射部位的危险比是(OR)22.1(P=0.006)。结论:玻璃体腔注射后感染眼内炎的几率很小,仅为0.025%。避免在偏下象限进行玻璃体腔注射可能会进一步减小眼内炎的发病率。

Hairy vetch (Vicia villosa roth.) has been recognized as a good candidate for weed suppressive mulch in organic no-till cropping systems. In our study, the allelopathic potential of hairy vetch, fall rye (Secale cereale L.) and winter wheat (Triticum aestivum L.) (extracted species) were evaluated at both vegetative and reproductive developmental stages (extract stage) based on the germination and radicle elongation of five response species using aqueous extracts in soil microcosms. Our study found hairy vetch shoot extract to have little allelopathic potential compared to fall rye or winter wheat, both species for which the allelopathic potential is well documented. Interestingly, hairy vetch was the only extracted species to increase in allelopathic suppression of radicle elongation at the reproductive stage when plant biomass is near maximum. This result was conceivably due to the increased concentration of the putative allelochemical cyanamide in reproductive tissue. Chemical inhibition of radicle elongation in this extract, however, was only observed in the domesticated response species wheat (Triticum aestivum L.) and canola (Brassica napus L.). The allelopathic effect on germination varied and depended on extracted species, extract stage, and response species;whereas the effect on radicle elongation was similar among extracted species, yet unique within response species. This research demonstrated that allelopathy studies should include multiple allelopathic and response species to accurately quantify the magnitude of chemical effects among allelopathic species and to rule out potential phytotoxic chemical defense/detoxification mechanisms that exist in some response species.

Architects and planners have been at the forefront of envisioning a future built environment for millennia. How ever,fragmental view s that emphasize one facet of the built environment,such as energy,environment,or groundbreaking technologies,often do not achieve expected outcomes. Buildings are responsible for approximately one-third of w orldw ide carbon emissions and account for about 40% of primary energy consumption in the U. S. In addition to achieving the very ambitious goal of reducing building-associated greenhouse gas emissions by75% by 2050,buildings must improve their functionality and performance to meet current and future human,societal,and environmental needs in a changing w orld. In this article,w e introduce a new framew ork to guide potential evolution of the building stock in the next century,based on greenhouse gas emissions as the common thread to investigate the potential implications of new design paradigms,innovative operational strategies,and disruptive technologies. This framew ork emphasizes integration of multidisciplinary know ledge,scalability for mainstream buildings,and proactive approaches considering constraints and unknow *** framew ork integrates the interrelated aspects of the built environment through a series of quantitative metrics that aim to improve environmental outcomes w hile optimizing building performance to achieve healthy,adaptive,and productive buildings.
