Most Americans smoke or are exposed to secondhand smoke (SHS) on a daily basis. Current tobacco treatment guidelines recommend the use of the 5As model to screen and treat primary tobacco users. Evidence supports that SHS is harmful, that the diseases caused by SHS are preventable, and that public health policies and individual counseling are effective in reducing exposure. Further, smoke-free ...

We report on frictional strengthening (healing) in granular quartz gouge as a function of time of true stationary contact. To distinguish between the slip-dependent [Ruina, 1983] and time-dependent [Dieterich, 1979] friction constitutive laws, we designed tests similar to conventional slide-hold-slide (SHS) tests except that shear load was completely removed prior to holds. We find large healin...

Cu3SbSe3-based composites have been prepared by self-propagating high-temperature synthesis (SHS) combined with spark plasma sintering (SPS) technology. Phase composition and microstructure analysis indicate that the obtained samples are mainly composed of Cu3SbSe3 phase and CuSbSe2/Cu2–xSe secondary phases. Our results show that the existence of Cu2–xSe phase can clearly enhance the electrical...

We consider Stochastic Hybrid Systems (SHSs) for which the lengths of times that the system stays in each mode are independent random variables with given distributions. We propose an approach based on a set of Volterra equations to compute any statistical moment of the state of the SHS. Moreover, we provide a method to compute the Lyapunov exponents of a given degree, i.e., the exponential rat...

RESUME. Le projet D4Humanities s’inscrit dans le champ des Humanités numériques – comment permettre l’exploration des données de la recherche en SHS (corpus textuels ou oraux, données brutes, images...) avec des techniques numériques (text and data mining, cartographie, visualisation...) afin de construire un sens nouveau ? Il s’inscrit dans la continuité des travaux du laboratoire GERiiCO et d...

Methods: A total of 748 students (748 eyes) from the primary school group (PS: 483 eyes), middle school group (MS: 78 eyes) and senior high school group (SHS: 187 eyes) were included in this prospective observational case series study. The refractive error values were determined using an automatic refractometer. The spherical refractive error, cylinder power and axis were measured by non-cyclop...

Square-shaped boron carbide ceramic composites have been produced by spark plasma sintering with the addition of 5 to 20 vol % titanium metal powder in B4C matrix order initiate an situ self-propagating high-temperature synthesis (SHS) TiB2. The SHS reaction not only enhances many physical and mechanical properties B4C, but also reduces required temperature pressure because enthalpy between met...

1. Abstract The aim of this paper is to show the calculation and optimization of a steel frame according to Eurocode 1 and 3 (parts 1.1 and 1.2). A comparison is made using square hollow section (SHS) columns and SHS or rectangular hollow section (RHS) for beams at a pressure vessel supporting frame (Figure 1). Optimizing for fire resistance for a given time it shows the prize of safety, the re...

This survey addresses stability analysis for stochastic hybrid systems (SHS), which are dynamical systems that combine continuous change and instantaneous change and that also include random effects. We reemphasize the common features found in most of the models that have appeared in the literature, which include stochastic switched systems, Markov jump systems, impulsive stochastic systems, sw...

Plentiful studies are reported on the semi-rigid behavior of joints between open section H shaped beam and column, but researches focusing on the semi-rigid performance of joints between square/rectangular hollow section (SHS/RHS) column-to-H shaped beam is to lag a lot. Most studies shows that when the SHS/RHS column connecting the H beam without internal diaphragm, the joints behavior is semi...
