Data fusion approach is investigated to avoid suction in the left ventricular assist system (LVAS) using a nonpulsatile pump. LVAS requires careful control of pump speed to support the heart while preventing suction in the left ventricle and providing proper cardiac output at adequate perfusion pressure to the body. Since the implanted sensors are usually unreliable for long-term use, a sensorl...

BACKGROUND The effects of physical therapy on heart rate variability (HRV), especially in children, are still inconclusive. OBJECTIVE We investigated the effects of conventional physical therapy (CPT) for airway clearance and nasotracheal suction on the HRV of pediatric patients with acute bronchiolitis. METHOD 24 children were divided into two groups: control group (CG, n=12) without respi...

In this paper, we propose a novel tactile display by controlling suction pressure. The method is based on our discovery of an illusion that pulling a skin through a hole creates a sensation as if a stick is pushing the skin. Based on this property of perception and multi-primitive stimulation method, we confirmed that we can produce tactile sensation from concentrated pressure to smooth surface...

An analysis is performed to study the heat transfer characteristics of steady mixed convection flow over a permeable vertical flat plate embedded in an anisotropic fluid-saturated porous medium. The effects of uniform suction and injection on the flow field and heat transfer characteristics are numerically studied by employing an implicit finite difference Keller-box method. It is found that du...

The efficiency of an alternative method of collection (by suction of water) for the study of Culicidae and Chironomidae (Diptera), Scirtidae (Coleoptera) and Coenagrionidae (Odonata) in bromeliads with different foliar architecture in a restinga at Florianópolis, SC, Brazil, was studied. The alternative method was less efficient to collect Culicidae and Chironomidae (Wilcoxon test p < 0.05) and...

INTRODUCTION The design of a surgical rotary vacuum shaver as a predecessor to the microdebrider has been attributed to Urban in 1968. His targeted use of this device to assist in the removal of acoustic neuromas did not find general use. Powered shavers were subsequently adopted in the field of orthopedic surgery and reintroduced successfully in the 1990s into otolaryngology for use in endosco...

In this paper, the transient refrigerant gas flow in a two-cylinder rolling piston type rotary compressor is simulated using STAR-CD, a general computational fluid dynamics (CFD) software. Three models with different suction piping systems are calculated respectively, one is two suction pipes were connected from accumulator to each cylinder separately (separate suction piping system), the other...
