background: different environmental conditions, such as high temperature or exposure to some chemical agents, may affect the force decay of different methods of space closure during orthodontic treatment. the aim of this in vitro study was to evaluate the force decay pattern in the presence of tea as a popular drink in some parts of the world and two mouthwashes that are usually prescribed by t...

To examine how repeated cooling of fingers with a rest pause schedule at work affects cold-induced vasodilatation (CIVD), pain and cold sensation in fingers, six healthy men aged 21 to 23 years immersed their left index fingers six times in stirred water at 10 degrees C for 10 minutes. After each cold-water immersion of the fingers, 5-minute rest pause was taken to observe the recovery process ...

Dual-language immersion programs have received a great deal of attention from parents, researchers, and policymakers. The supporters of dual-language immersion see the promise ofprovidingfirst-language instruction for children with nonEnglish-speaking backgrounds, while simultaneously offering monolingual children access to non-English languages. In this article, Guadalupe Vaidés concentrates o...

OBJECTIVES The aim of the present study was to investigate the composition, morphology, bulk structure and ionic release of two brands of titanium orthodontic brackets: Orthos2 (Ormco, USA) and Rematitan (Dentaurum, Germany). METHODS Five specimens of each group were examined with computerized X-ray microtomography, to reveal the morphology and structure of brackets, whilst resin-embedded and...

Whether spray or immersion fixation results in higher adequacy rates for thyroid fine-needle aspiration is not known. I compared 1-year adequacy rates, number of cells, and atypia rates for immersion fixation with split spray fixation and immersion. Adequacy rates increased from 71.9% (289/402) for complete immersion to 78.1% (332/425) with spray fixation of half of the slides (P = .02). The sp...

Despite the word's common usage by gamers and reviewers alike, it is still not clear what immersion means. This paper explores immersion further by investigating whether immersion can be defined quantitatively, describing three experiments in total. The first experiment investigated participants' abilities to switch from an immersive to a non-immersive task. The second experiment investigated w...

PURPOSE To compare 2 methods of axial length measurement, immersion ultrasonography and partial coherence interferometry, and to elucidate surgical outcomes based on immersion measurements. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS Axial length measurements in 50 cataractous eyes were obtained by optical biometry (IOLMaster, Zeiss Humphrey Systems) and immersion ultrasound ...

Welding is a process of joining two or more metals into form connection using heat process. This study aims to determine the value bending test strength on SMAW welding E6013 electrode, variations electric current, namely 100A, 110A, 120A and cooling media. The method used with AISI 1037/ST37 material. type seam V-slope slope 600 according AWS d1.1:2000 standardization. carried out Three Point ...

Given previous studies indicating a significant correlation between anxiety and presence, the purpose of this investigation was to explore the direction of the causal relationship between them. The sample consisted of 31 adults suffering from snake phobia. The study featured a randomized within-between design with two conditions and three counterbalanced immersions: (a) a baseline control immer...

Exercise induces arterial flow patterns that promote functional and structural adaptations, improving functional capacity and reducing cardiovascular risk. While heat is produced by exercise, local and whole-body passive heating have recently been shown to generate favorable flow profiles and associated vascular adaptations in the upper limb. Flow responses to acute heating in the lower limbs h...
