Enhancing the effective expansion ratio to further improve fuel consumption, this study implemented a kind of Variable Port Timing (VPT) by designing vertically moving sleeve on outside scavenging port low-speed two-stroke diesel engine with 340 mm bore. A 3D Computational Fluid Dynamics (CFD) model was constructed and calibrated investigate influence VPT strategy performance internal gas excha...

OBJECTIVE To evaluate the efficacy and safety of actovegin in patients with diabetic polyneuropathy. RESEARCH DESIGN AND METHODS In this multicenter, randomized, double-blind trial, 567 patients with type 2 diabetes received 20 intravenous infusions of actovegin (2,000 mg/day) (n = 281) or placebo (n = 286) once daily followed by three tablets of actovegin (1,800 mg/day) or placebo three times ...

OBJECTIVE The aim of the present study was to quantify the sensory and functional effects resulting from a short-duration (30 min) exposure to hand-arm vibration. SUBJECTS AND METHODS Nine subjects went through nine laboratory experiments. For 32 min they grasped a handle vibrating at three different amplitudes (5, 20, and 80 ms-2) and at three frequencies (31.5, 125, and 500 Hz). Additionall...

We consider the problem of evaluating in streaming (i.e. in a single left-toright pass) a nested word transduction with a limited amount of memory. A transduction T is said to be height bounded memory (HBM) if it can be evaluated with a memory that depends only on the size of T and on the height of the input word. We show that it is decidable in coNPTime for a nested word transduction defined b...

maintaining deciduous teeth in function until their natural exfoliation is absolutely necessary. vital pulp therapy (vpt) is a way of saving deciduous teeth. the most important factors in success of vpt are the early diagnosis of pulp and periradicular status, preservation of the pulp vitality and proper vascularization of the pulp. development of new biomaterials with suitable biocompatibility...

vital pulp therapy (vpt) is a biologic and conservative treatment modality to preserve the vitality and function of the coronal or remaining radicular pulp tissue in vital permanent teeth. a search was conducted via the cochrane database, pubmed, medline, and ovid for any articles with the criteria for “pulp-capping,” or “pulp-capping materials” and “vpt outcomes” from 1978 to mid 2014. all art...

background: the incomplete maturation of brain in preterm children results in long-term neurodevelopmental impairment. this study aimed to investigate the static balance function in children with a history of preterm birth. methods: participants were 31 preterm children including 21 moderately preterm (mpt), 10 very preterm (vpt), and 20 term children aged 5.5 and 6.5 years. the cervical vestib...

The cerebral hemispheres of the human brain have unique functional properties of information processing; an asymmetry that captures cerebral lateralization. Among cognitive functions, language is one of the most lateralized with left-sided dominance for the production and processing of language. Previous work has shown that the foundation of language circuitry emerges in the late second and thi...
