The present paper aims to improve the dynamical balancing of a slider-crank mechanism. This mechanism has been widely used in internal combustion engines, especially vehicle engines; hence, its dynamical balancing is important significantly. To have a full balance mechanism, the shaking forces and shaking moment of foundations should be eliminated completely. However, this elimination is usuall...

If C is a compact subset of R and H is a halfspace bounded by a hyperplane π, the set C̃ obtained by shaking C on π is defined as the set contained in H, such that for every line ` orthogonal to π, C̃ ∩ ` is a segment of the same length as C ∩ `, and one of its endpoints is on π. It is shown that there exist d + 1 hyperplanes such that every compact set can be reduced to a simplex, via repeated s...

The aim of the present study was to investigate the potential effects of mechanical shaking on the purity, activity, differentiation and possible apoptosis of rat bone marrow mesenchymal stem cells (BMSCs). Based on the whole bone marrow adhesion method, different durations and frequencies of mechanical shaking were used on primary cells. The biomarkers, CD29, CD90, CD45 and CD31, in addition t...

BACKGROUND To estimate the prevalence of shaking and smothering and to determine risk factors in a population-based sample of mothers with 4-month-old infants in Japan. METHODS We administered a questionnaire to women who participated in a 4-month health checkup program in Aichi Prefecture, Japan (n = 6487; valid response rate, 66.8%), and assessed frequency of shaking and smothering during t...

Few studies have investigated the prevalence of shaking and smothering and whether they are associated with co-sleeping. In Japan, co-sleeping is common during infancy and early childhood. This study investigates the prevalence of shaking and smothering and their associations with co-sleeping among 4-month-old infants in Japan. A questionnaire was administered to mothers who participated in a 4...

Relatively little research has been conducted to systematically quantify the nationwide earthquake risk of gas pipelines in US; simultaneously, national guidance is limited for operators across country consistently evaluate their assets. Furthermore, many challenges and uncertainties exist a comprehensive seismic assessment pipelines. As first stage systematic assessment, we transmission conter...

Head-shaking nystagmus. Head-Shaking Nystagmus (HSN) is a latent spontaneous vestibular nystagmus provoked by rapid passive head shaking around a vertical axis. HSN is not specific in distinguishing peripheral hypofunction from more central vestibular imbalances. This test is an excellent bedside test for detecting unilateral vestibular hypofunction but further rotatory and caloric testing will...

Thermoviridin appeared to be an organic acid which was dialyzable. The antibiotic showed maximum absorption in the range of 268 to 272 m,u. Thermoviridin was primarily active against the gram positive bacteria tested. A preliminary toxicity test in mice, consisting of a single intraperitoneal injection of 32 mg of material which had 25 thermoviridin units per mg, did not cause death in any case.

Limb-shaking is a specific clinical feature of transient ischaemic attacks that has been associated with a high-grade stenosis or occlusion of the internal carotid artery. The aim of this study was to describe the clinical characteristics of limb-shaking in patients with internal carotid artery occlusion and to investigate whether patients with limb-shaking have a worse haemodynamic state of th...
