to determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in ardebil agricultural research station for two years (2001 and 2002). the experiment was in a split split splot on the basis of completely randomized block design with three replications. pre-germination and non pre-germin...

Sporadic cases of chemical poisoning have occurred in Japan recently, and even though these cases are rare, this situation is not permissible. These cases involve not only newly identified types of poisoning, but also the reemer-gence of poisoning with known hazardous chemicals. Recent examples of known types of poisoning are lead poisoning, lung cancer caused by exposure to beryllium, and blad...

Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

Nanocrystalline Copper Nanostructures In article 2205302, Maxence Menétrey and co-workers present a novel approach for microstructure control in nanopillars synthesized by electrohydrodynamic redox 3D printing. Variations the deposition voltage allow on-the-fly grain size modulation additively manufactured nanostructures.

As the world’s store of knowledge increases, and knowledge-workers in contemporary organizations face the imperative of consulting that record, and contributing to it, in order to satisfy a diversity of users and uses, we need to find more efficient and effective ways of dealing with the vast volumes, and have strategies, processes, and systems for managing them. Hypertext technology is a good ...

Four studies conducted in the light metal, electrotechnical and printing industries are described. The purpose was to determine the applicability of the systems approach to occupational accidents. The data consisted of 291 accidents and 701 controls. The stable characteristics of the workers or the environments were not good predictors of accidents. The clearest differences between the accident...

A visible light-induced silver printing technique is applied to patterning flexible electronics on ultrasmooth and transparent nanocellulose paper, as described in article number 2101598 by Xinyu Liu co-workers. The printed electronic devices possess high conductivity, superior mechanical electrical stability, good sustainability.

AIMS To quantify occupational ill health resulting from dermatitis in the UK printing industry and to explore links with particular processes and activities. METHODS Approximately 2600 members of the Graphical, Paper and Media Union living in Nottinghamshire were sent a self completion questionnaire. A sample of respondents, both those who reported current skin problems and those who did not,...
