This paper mathematically analyses the varying magnitude of production loss, which may occur due to idle time (inprocess waiting time and traveling time) on a linear walking worker assembly line. Within this flexible and reconfigurable assembly system, each worker travels down the line carrying out each assembly task at each station; and each worker accomplishes the assembly of a unit from star...

Extracellular proteins of wild-type Vibrio alginolyticus were compared with those of copper-resistant and copper-sensitive mutants. One copper-resistant mutant (Cu40B3) constitutively produced an extracellular protein with the same apparent molecular mass (21 kDa) and chromatographic behavior as copper-binding protein (CuBP), a copper-induced supernatant protein which has been implicated in cop...

It has become clear that copper toxicity is playing a major role in Alzheimer's disease; but why is the brain copper toxicity with cognition loss in Alzheimer's disease so much different clinically than brain copper toxicity in Wilson's disease, which results in a movement disorder? Furthermore, why is the inorganic copper of supplement pills and in drinking water so much more damaging to cogni...

the interaction of copper oxide nanoparticles and copper ions and proteinase k from tritirachium album limber has been investigated employing uv spectroscopy and kinetics measurements. the aim of this study was to evaluate the effect of nanoparticles of cuo for proteinase k. in this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase k stabilit...

Background: Multisource feedback (MSF) is increasingly being used as one of the components in revalidation and recertification processes to guide physicians’ continuing professional development. Data provided by coworkers (e.g., nurses, pharmacists, technicians) are recognized as integral for assessing a physician’s communication, teamwork and interprofessional abilities. The purpose of this st...

Work stress is recognized globally as a social determinant of worker health. Therefore we explored whether work stress related factors explained national differences in health and productivity (gross domestic product (GDP)). We proposed a national worker health productivity model whereby macro market power factors (i.e. union density), influence national worker health and GDP via work psychosoc...

The outbreak of severe acute respiratory syndrome (SARS) in 2003 provided valuable lessons for protecting health workers during an influenza pandemic or other public health crisis. In its final report, the SARS Commission concluded that a key lesson in worker safety was the precautionary principle. It stated that reasonable actions to reduce risk should not await scientific certainty. As recomm...

Worker honeybees, Apis mellifera, police each other's reproduction by killing worker-laid eggs. Previous experiments demonstrated that worker policing is effective, killing most (∼98%) worker-laid eggs. However, many queen-laid eggs were also killed (∼50%) suggesting that effective policing may have high costs. In these previous experiments, eggs were transferred using forceps into test cells, ...

HIV prevalence is disproportionately high among female sex workers compared to the general population. Many African countries lack useful data on the size of female sex worker populations to inform national HIV programmes. A female sex worker size estimation exercise using three different venue-based methodologies was conducted among female sex workers in all provinces of Rwanda in August 2010....
