Grid research, rooted in distributed and high performance computing, started in midto-
late 1990s when scientists around the world acknowledged the need to establish an
infrastructure to support their collaborative research on compute and data intensive
experiments. Soon afterwards, national and international research and development
authorities realized the importance of the Grid and gave it a primary position on their
research and development agenda.

The workplace as a health promotion setting
Workplace health promotion (WHP) programmes, targeting physical
inactivity and unhealthy dietary habits, are effective in improving health-
related outcomes such as obesity, diabetes and cardiovascular disease
risk factors. Enhancing employee productivity, improving corporate
image and moderating medical care costs are some of the arguments
that might foster senior management to initiate and invest in WHP
The bremsstrahlung beam with energy end point of 65M eV created when the e− beam with energy of 65M eV irradiated to thin wolfram target was used to irradiate to TiO2 sample in order to make the 46 Ti (γ, pn)44m,g Sc reaction. The gamma spectrum
of Sc44m,g was analyzed by the gammavision spectrometry with HPGe detector at linear accelerator laboratory in POSTECH, Korea.
Radioactive sources which used to study were the standardized radioactive of common monoenergetic radionuclide Cs137 and standardized multigamma Co60, Ba133, Eu152. Determination of the absolute efficiency curve and energy resolution as a function of energy of GEM40P4 HPGe spectrometer are presented in this paper.
The studies of ultrashort laser pulse interactions with single atoms, molecules,
nanoparticles and condensed matter is a hot topic of modern physics, since the
obtained results stimulate the development of fundamental principles of light-matter
interaction and, at the same time, find the wide area of practical applications.
This volume contains the contributions devoted both to the discussion of general
principles and fundamental experiments, as well as the different practical applications.
INTRODUCTION: SCIENTIFIC EXPLORATION AT THE HIGH-ENERGY FRONTIER
The major high-energy physics (HEP) experiments of the next twenty years will break new ground in our understanding of the fundamental interactions, structures and symmetries that govern the nature of matter and space-time. Among the principal goals are to ﬁnd the mechanism responsible for mass in the universe, and the ‘Higgs’ particles associated with mass generation, as well as the fundamental mechanism that led to the predominance of matter over antimatter in the observable cosmos.
The wavelength shift effect of the Whispering Gallery Mode (WGM) laser with Er3+ /Yb3+ co-doped phosphate glass microsphere has been investigated. The experiment was carried out by half fiber taper coupling technique. The microsphere lasers have been pumped at 980 nm to take full advantage of energy transfer effect from ion Ytterbium to ion Erbium. The WGM’s wavelength shift were analyzed for sphere diameters of 90 µm. The observed lasing lines extends from 1532 nm to 1611 nm.
Some twenty five countries have experimented with environmental accounting over the
past twenty years. A few European countries have established physical accounting
systems which are routinely compiled and applied to economic and environmental
policy-making. Many other countries have undertaken more limited or one-time
experiments and case studies with monetary environmental accounts, focused on issues
such as forestry, soil erosion, and minerals depletion. A few examples suggest the
richness of their experience.
