GERMANY Sintered metal filters. Porous sintered metal filters have been used in the U.S.A. for some time and are now becoming increasingly important in Europe for chemical equipment. The structure of porous sintered metals and the influence of granulation of the used powder on the arrangement of the desired filtering channels are explained, in order to show their possible applications. Present‐day available materials, their pressure drop and chemical resistance, and mechanical and physical properties are discussed.

As a protective coating, zinc occupies the leading position amongst the metals. Here we are concerned mainly with the corrosion of zinc galvanizing in many of its applications. The position of zinc relative to the other commonly used metals for coatings for the protection of steel is briefly compared.

Wettability and corrosion inhibition. In the course of an ambitious research programme on corrosion inhibitors and related problems, the Institute of Chemistry at Ferrara, Italy, has investigated certain special aspects of corrosion inhibition in the presence of wetting agents. It would appear that the surface conditions have an important bearing on the mechanism of the corrosion phenomena, and that the action of the wetting agents tends to modify the distribution of the local cells so that the corrosion mechanism is re‐orientated.

This paper aims to Separation and sorting of biological cells is desirable in many applications for analyzing cell properties, such as disease diagnostics, drugs delivery, chemical processing and therapeutics.

Acoustic energy-based bioparticle separation is a simple, viable, bio-compatible and contact-less technique using, which can separate the bioparticles based on their density and size, with-out labeling the sample particles.

Conventionally available bioparticle separation techniques as fluorescence and immunomagnetic may cause a serious threat to the life of the cells due to various compatibility issues. Moreover, they also require an extra pre-processing labeling step. Contrarily, label-free separation can be considered as an alternative solution to the traditional bio-particle separation methods, due to their simpler operating principles and lower cost constraints. Acoustic based particle separation methods have captured a lot of attention among the other reported label-free particle separation techniques because of the numerous advantages it offers.

This study tries to briefly cover the developments of different acoustic-based particle separation techniques over the years. Unlike the conventional surveys on general bioparticles separation, this study is focused particularly on the acoustic-based particle separation. The study would provide a comprehensive guide for the future researchers especially working in the field of the acoustics, in studying and designing the acoustic-based particle separation techniques.

The study insights a brief theory of different types of acoustic waves and their interaction with the bioparticles is considered, followed by acoustic-based particle separation devices reported till the date. The integration of acoustic-based separation techniques with other methods and with each other is also discussed. Finally, all major aspects like the approach, and productivity, etc., of the adopted acoustic particle separation methods are sketched in this article.

Social media are central to the creation and maintenance of social relations, including romantic relations. While much of the scholarship has examined how social media play a role in the initiation and maintenance of romantic relations, little is known about their role in romantic dissolution. This chapter fills this gap by examining the kinds of strategies young adults employ to cope with the aftermath of a romantic breakup complicated by Facebook. Based on qualitative analysis of 10 interviews with young adults, the authors propose a typology of Facebook coping strategies for romantic breakups. The typology includes seven types of coping strategies with 12 subtopics and 25 specific actions linked to the subtopics. The authors find that those coping with a breakup engage in erasing and avoiding breakup reminders and digital traces, as they perceive them as hurtful. They regulate their use of Facebook and limit Facebook communication with the ex. An important coping strategy used was to express their emotions via Facebook content, often aimed at the ex-partner. They also use Facebook to seek support and new information about the ex, including about potential new romantic interests. Others preferred to avoid information about the ex and either deleted the ex and their friends or chose to unsubscribe to updates. Coping strategies included preventative measures such as changing passwords, blocking the ex, and adjusting privacy settings. We found our participants engaged in both goal-directed and emotionally based coping strategies. Yet, the findings suggest a tendency to rely more extensively on goal-directed coping strategies by actively addressing the breakup stressor. We also note that coping strategies specific to Facebook are more likely to be used than traditional offline forms of coping. This exploratory study serves as a starting point to better understand the role that Facebook plays in mediating online behaviors following a romantic dissolution, such that these strategies can be subsequently evaluated in terms of usefulness in clinical coping recommendations.

This paper gives a bibliographical review of the finite element and boundary element parallel processing techniques from the theoretical and application points of view. Topics include: theory – domain decomposition/partitioning, load balancing, parallel solvers/algorithms, parallel mesh generation, adaptive methods, and visualization/graphics; applications – structural mechanics problems, dynamic problems, material/geometrical non‐linear problems, contact problems, fracture mechanics, field problems, coupled problems, sensitivity and optimization, and other problems; hardware and software environments – hardware environments, programming techniques, and software development and presentations. The bibliography at the end of this paper contains 850 references to papers, conference proceedings and theses/dissertations dealing with presented subjects that were published between 1996 and 2002.

This paper describes a studio model that attempts to bridge the gap between conventional design studio settings and professional practice, by adopting design-build principles that incorporate experiential learning theory, derived from the early research of Dewey, Lewin, and Piaget. Part of the dichotomy of the profession is the dynamic difference in the established representational tools of the trade and the result of the built environment. This disconnect exists because the tools of the trade utilize two dimensional explanations about a three dimensional place, typically comprised of drawings in the form of plans, elevations, and perspectives. Additionally, there is a dynamic difference in scale that exists between these tools and the environments they represent. Thus, design educators tend to teach representational techniques without teaching a clear understanding of what they represent. This gap in education creates a gap in the profession. The described case studies outline an alternative studio model that is intended to introduce some of the “realities” often missing in a conventional studio approach. Each of the case studies involved second year Interior Design students, who were given the parameters of an existing space with specific user needs. The students had to design and then physically construct that interior environment all within a ten week time period (one academic quarter). By creating a more “hands-on” learning environment, it is the hope that students retain that knowledge in a more meaningful and lasting way, with the ability to transfer that experience over to similar situations in other studio settings and within the professional practice.

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.

This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.

This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.

This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.
