Stability of Ladders when Working at heights and Safety while performing this type of work
Journal of Physics: Conference Series, 2019 Abstract The analysis of industrial injuries when working at heights is conducted. Statistics show that a fall from a height takes more than 30% of the total number of accidents. Operations with the help of ladders are the most common type of works at heights.

Twenty‐First Century Butlers and the New Spirit of Service
The British Journal of Sociology, EarlyView.ABSTRACT More than 50 years ago, Lewis Coser argued that the “servant” had become obsolete, claiming that such a “premodern” occupation could not function within modernity without religious legitimations. However, with parts of the contemporary service sector exhibiting the very characteristics that Coser viewed as “premodern”—especially within ...

Journal of Medical Imaging and Radiation Oncology, EarlyView.ABSTRACT Introduction Whole‐body CT (WBCT) is central to major trauma assessment, but indiscriminate use carries a substantial radiation burden. The Central Region Trauma Network's Early Radiological Imaging in Major Trauma Guideline (CPG154), adopted at this centre, specifies criteria for WBCT and excludes low‐energy falls from standing height.

Ladder heights and the Markov-modulated M/G/1 queue
Stochastic Processes and their Applications, 1991 This paper is concerned with the Markov-modulated M/G/1 queue with both the arrival rate and the distribution of service time depending on the actual state of the Markov environmental process. For analysing the distribution of the steady-state waiting time of this queueing system, a random walk setting is considered which leads to a Wiener-Hopf ...

Rebuilding the Ladder? Contemporary Contests Over Industrial Policy
Global Policy, EarlyView.ABSTRACT Does the greater embrace of industrial policy globally signal the emergence of a New Washington Consensus? We show that the multiplication of industrial policies, while consequential, signals neither normalisation nor consensus. Rather, industrial policy is increasingly the object of contestation over norms and practices of state ...

The Control Effectiveness of Water and Soil Conservation with the Planting Model of Hilly Tea Farm
Shuitu baochi yanjiu, 2004 Under the condition of the same height planting,the annual average amount of soil erosion ranges from 3 198 to （27 189 kg/hm2 ）in hilly tea farm of Chongqing.With the rising of slope,the soil loss is more serious.Raising the rate of ground cover could ...

Andrology, EarlyView.ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Height and well-being amongst older Europeans [PDF]
This paper uses a cross-country representative sample of Europeans over the age of 50 to analyse whether individuals’ height is associated with higher or lower levels of well-being.

Asymptotic expansions on moments of the first ladder height in Markov random walks with small drift [PDF]
Advances in Applied Probability, 2007 Let {(Xn, Sn), n ≥ 0} be a Markov random walk in which Xn takes values in a general state space and Sn takes values on the real line R. In this paper we present some results that are useful in the study of asymptotic approximations of boundary crossing problems for Markov random walks.
