The LEP energy upgrade up to fi =189 GeV has allowed us to extend substantially the potential of searches for new physics. Results on searches for Higgs bosoms and supersymmetric particles obtained by the ALEPH, DELPHI, L3, and OPAL experiments are reported. No evidence of any signal is observed. Therefore, new limits on the Higgs boson masses as well as on the masses of the various supersymmet...

We would like to congratulate Fruchter et al 1 for their ingenious, effective, and minimally invasive way of treating the very challenging condition of bronchopleural fi stulas as reported in a recent issue of CHEST (March 2011). However, because we were cited in their work, we must make a correction. The misunderstanding is that our fi rst publication was a case report of our fi rst patient (5...

AIMS The need to combine active employment and parenthood is a reality for many parents today. Knowing more about which work place factors are associated with better or worse health could help employers to form a work environment that provides optimal conditions to maintain or increase health and work engagement in this group. The aim of this study was to explore possible associations between d...

In the changing modern economy some new factors have been addressed that are of importance for productivity and economic growth, such as human skills, workplace organization, information and communication technologies (ICT) and knowledge sharing. An increasing number of companies and organizations are implementing measures to better address these factors, often referred to as 'the New Ways of W...

The aim of this study was to investigate the relationship between job stress with personality characteristics and organizational commitment. This study is descriptive and correlational. The study population comprised all nurses in 13-Aban hospital of Ghods city. The sample group consisted of 120 nurses who were selected through convenience sampling. Research instruments were HSE job stress ques...

Introduction In examining wireless-internet technologies (Wi-Fi), several ethical issues are exposed. While the unauthorized use of Wi-Fi is illegal in a few select cases, what is considered permissible still varies from state to state. What does not vary, however, is the fact that individuals are going to great lengths to locate unsecured wireless access points whether it is for their own bene...

In this paper the problem of obtaining the degree of flexibility that maximizes the total profit in an existing process flowsheet is addressed. Assuming a linear model for the process and given probability distribution functions for the uncertain parameters, the curve relating the expected revenue to the flexibility index is generated. An efficient stochastic optimization method is developed fo...

1. Given topological spaces X and Fand two continuous mappings ƒ o and jfi from X to F (denoted by fo, fi : X—> F) we say that ƒ o is homotopic to jfi (denoted by fo—fi) if there exists a continuous family of continuous mappings ht: X—+Y for O^t^l such that ho=fo and h =/ i . Intuitively fo<^fi if the map ƒ o can be continuously deformed into the map jfi. I t is easily seen [4; 7] that the rela...

Life expectancy has increased considerably throughout the world. In Bangladesh, life expectancy has increased from about 53 years in 1975 to 69 years in 2010. However, it is unknown whether the increase in life expectancy is simultaneously accompanied by an increase in disability-free life expectancy (DFLE). The purpose of the study described in this article was to explore the relationship betw...
