Synthesis of photoreactive solvent-free acrylic pressure-sensitive adhesives in the recovered system The present paper discloses a novel photoreactive solvent-free acrylic pressure-sensitive adhesive (PSA) systems, especially suitable for the so much adhesive film applications as the double-sided, single-sided or carrier-free technical tapes, self-adhesive labels, protective films, marking and sign films and wide range of medical products. The novel photoreactive solvent-free pressure-sensitive adhesives contain no volatile organic compounds (residue monomers or organic solvent) and comply with the environment and legislation. The synthesis of this new type of acrylic PSA is conducted in common practice by solvent polymerisation. After the organic solvent are removed, there remains a non-volatile, solvent-free highly viscous material, which can be processed on a hot-melt coating machine at the temperatures of about 100 to 140°C.

This paper proposes a new type of a self-controlled restrictor which can achieve a very high bearing stiffness in hydrostatic bearings. This self-controlled restrictor employs a floating disk to control the mass flow rate of the oil entering the bearing clearance according to changes of the applied load. Furthermore, a hydrostatic bearing with this restrictor can theoretically achieve an infinite stiffness when the mass of a floating disk is assumed to be zero. The static characteristics of a rectangular hydrostatic thrust bearing with this self-controlled restrictor are theoretically and experimentally investigated. It was consequently shown that the proposed hydrostatic thrust bearing can achieve a very high stiffness (nearly infinite stiffness) in a very wide range of applied load independent of supply pressure.

The appearance of concepts such as “Ambient Intelligent”, “Ubiquitous Computing” and “Context-Awareness” is causing the development of a new type of services called “Context-Aware Services” that in turn may affect users of mobile communications. This technology revolution is a a complex process because of the heterogeneity of contents, devices, objects, technologies, resources and users that can coexist at the same local environment. The novel approach of our work is the development of a ”Local Infrastructure” in order to provide intelligent, transparent and adaptable services to the user as well as to solve the problem of local context control. Two contributions will be presented: conceptual model for developing a local infrastructure and an architecture design to control the service offered by the local infrastructure. This infrastructure proposed consists of an intelligent device network to link the personal portable device with the contextual services. The device design is modular, flexible, scalable, adaptable and reconfigurable remotely in order to tolerate new demanding services whenever are needed. Finally, the result suggests that we will be able to develop a wide range of new and useful applications, not conceived at origin.

The skopos of this new type of church Bible is: ‘How would the source texts of the Bible have sounded in Afrikaans in the context envisaged for its hypothesised first audience(s)?’ Fully acknowledging the complexities of language as a dynamic and complex system embedded in the culture and conceptual world of its speakers, as well as the wide range of frames that are involved in the process of Bible translation as a difficult form of secondary communication, this article addresses two of the challenges of this ambitious project. In the first section the incongruence between the world of the Old Testament and speakers of Afrikaans is treated. Examples are provided of instances where both the nature of difficult secondary intercultural communication as well as the subjective theories of the host audience constrains the ‘directness’ of the translation. In the second section, some of the challenges of distinguishing between the formal and functional features of Biblical Hebrew are dealt with. The article concludes that, although the notion ‘communicative clue’ provides a useful heuristic device to act as point of departure for negotiations on the construal of the meaning of the text in the source language and host language respectively, the notion has to be supplemented by insights from the fields of cultural anthropology, cognitive linguistics and linguistic typology. A better understanding of how meaning ‘works’ (e.g. how linguistic expressions act as windows into the conceptual worlds of speakers, how the meaning of expressions may shift and develop, as well as processes of grammaticalisation) provides members of a translation team with some criteria to make informed decisions when they negotiate how the meaning of specific Biblical Hebrew constructions are to be construed ‘directly’ in Afrikaans.Keywords: Afrikaans Bibles; Bible translation; Biblical Hebrew; church Bible; code model; cognitive linguistics; cognitive semantics; communication model; communicative clue; direct translation; discourse marker; dynamic equivalent translation; functionalist tran

A new type of zeolite-based covalent organic frameworks (ZCOFs) was designed under different topologies and linkers. In this study, the silicon atoms in zeolite structures were replaced by carbon atoms in thiophene, furan, and pyrrole linkers. Through the adoption of this strategy, 300 ZCOFs structures were constructed and simulated. Overall, the specific surface area of ZCOFs is in the range of 300–3500 m2/g, whereas the pore size is distributed from 3 to 27 Å. Furthermore, the pore volume exhibits a wide range between 0.01 and 1.5 cm3/g. Screening 300 ZCOFs with the criteria towards methane storage, 11 preliminary structures were selected. In addition, the Grand Canonical Monte Carlo technique was utilized to evaluate the CH4 adsorption ability of ZCOFs in a pressure ranging from 1 to 85 bar at a temperature of 298 K. The result reveals that two ZCOF structures: JST-S 183 v/v (65–5.8 bar) and NPT-S 177 v/v (35–1 bar) are considered as potential adsorbents for methane storage. Furthermore, the thermodynamic stability of representative structures is also checked base on quantum mechanical calculations.

In this paper the first thirty-two axisymmetric modes for steady-periodic waves in viscous compressible liquids contained in rigid, impermeable, circular tubes are calculated. These results end long speculation over the effects of viscosity on guided acoustic waves. Sixteen of the modes belong to a family of rotation-dominated modes whose existence was previously unknown. The thirty-two modes were computed for a wide range of frequencies, viscosities and wave-lengths.The modes were found through the use of the method of eigenvalleys, which also led to the discovery of backward-propagating waves, an exact analytical expression for the zeroth rotational mode eigenvalue, definitive boundaries between low and intermediate frequencies and between intermediate and high frequencies, and a new type of boundary layer, called a dilatational boundary layer.

A new-type high performance cold-patch mixture was made from new-type cold-patch asphalt emulsion, which is able to promote the adhesive effect of asphalt and aggregate. This new mixture boasts advantages such as good workability and being free from bad weather like rain and low temperature. During the production, the evaluation method of cold-patch asphalt material was improved by the adoption of rotary viscosity test and paper trail test. Field tests were carried out on some sections of Linchang Expressway. When compared to existing repair materials, the new-type cold-patch mixture showed better repair effect as well as the potential for a wide range of promotion.

Among all the joints in the human body, the elbow joint is the one which most easily suffers from stiffness. Thus, a progressive stretching static adjustable elbow splint is necessary for a post-traumatic or post-operative situation in treating of elbow problems. We developed a new type of static adjustable elbow splint, which can provide flexion and extension in a wide range of motion. The splint also has a self-adjustable spiral rod. Patients can adjust the motion arc according to his tolerance, which may reduce the iatrogenic injury caused by forceful manipulation. The splint has two rotation hinges to provide self-adjustment of rotation center. We can apply this new type of splint for post-operative rehabilitation of elbow surgery, such as fracture-dislocation fixation, contracture release, arthroplasty and non-operative treatment of elbow injury.

The Stability

This paper examines operation modes of a mixed compression air intake with a rectangular cross-section at Mach number 2.0. The perfect gas model was used for the calculation. Calculations were performed for three values of Mach numbers: 1.8, 2.0 and 3.0. k–ε turbulence model was chosen for describing flows with large adverse pressure gradients. Two-dimensional and three-dimensional configurations of the air intake device were examined. Versions of geometry with and without the boundary layer drain system were considered. The influence of the boundary layer drain system on the flow in the air intake and its characteristics was established. Throttle characteristic curves were formed for all the considered modes with regard to the averaged flow parameters. A comparison of the calculation and experimental data showed a good agreement of the results. The obtained results can serve as a basis for further optimization and improvement of the efficiency of the aircraft design layout, increase in the stability margin of air intakes, as well as development of software systems for regulating supersonic input devices.
