with zinc coating can be obtained by several ways. Tailor welded blanks is a well established technology and already in series application. Tailored-properties by partial heating is a new technology that makes different mechanical properties available on one component made of one blank.
Zink-beschichtete, pressgehärteter Bauteile mit maßge-schneiderten Eigenschaften: Vorteile und HerausforderungenZur Herstellung pressgehärteter BauZusammenfassung: teile mit anforderungsspezifischen Eigenschaften wurden in den letzten Jahren verschiedene Technologien und Methoden entwickelt. Während sich verzinkte Bauteile aus lasergeschweißten Platinen aus phs-ultraform bereits im Serieneinsatz bewährt haben, ist die Methode, maßgeschnei-derte Eigenschaften durch partielle Erwärmung einzustellen, vor der Umsetzung in Serienanwendungen.
This article investigates the phenomenon of rhoticity in the speech of black speakers of South African English. Historically, South African English is non-rhotic. Thus, any shift towards a rhotic variant is a significant language change. Thirty-nine interviews were conducted with both males and female participants. The two groups were evenly split into more and less affluent groups. It was found that rhoticity in Black South African English is preferentially a female phenomenon, found most frequently in affluent female speakers. Male speakers also exhibit this feature but less frequently so. Of the affluent females 90% displayed some degree of rhoticity. None of the less affluent males displayed any rhoticity. The data gathered seem to suggest that a covert prestige exists amongst men to use their African languages. This is in contrast to the overt prestige amongst women to use English. The research thus isolates an important socio-economic stratification, providing evidence that both gender and affluence influences the degree in which a group creates a new language variety. We also speculate about reasons for the adaptation of rhoticity in affluent, female speakers, thus providing the basis for a follow-up study in which the sociological dimension of this linguistic phenomenon is explored in more detail.
A case study evaluated how physical medical records are managed and curated at a large tertiary hospital. It was found that the current microfiching technology was outdated, ineffective, and in many cases an impediment to appropriate care. Alternative recordkeeping techniques were evaluated. A proposal for a localised electronic medical record (EMR) system, disseminated by tablet computer, is presented in this paper. Issues about ethics and access to information are explored, and some of the issues that have affected global implementation are highlighted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
