Heat transfer enhancement technology has the aim of developing more efficient systems as demanded in many applications. An available passive method is represented by the employ of rough surfaces. Transversal turbulators enhance the heat transfer rate by reducing the thermal resistance near surfaces, because of the improved local turbulence; on the other hand, higher losses are expected. In this...

BACKGROUND Managing "spaghetti syndrome," the tangle of therapeutic cables, tubes, and cords at patients' bedsides, can be challenging. OBJECTIVES To assess nurses' perceptions of the effectiveness of a novel banding device in management of spaghetti syndrome. METHODS A simple color-coded elastomeric banding strap with ribbed flaps was attached to bed rails of adult critical care patients t...

Abstract. Purpose. The work’s aim is to check the stability loss hypothesis with snap-through effect of ribbed-annular dome's upper tier on a full-scale model by experimental tests, and confirming nonlinear tier's work under external load. Methodology. ribbed-ring dome circumscribe in plan as circle diameter 18 m rise ratio span - 1/4, which consisted 8 ribs had 6 tiers height, was taken an dom...

The genus Astrantia L. is a perennial plant which belongs to the Umbelliferae family and is represented by only A. maxima Pallas which has two subspecies (subsp. maxima and subsp. haradjianii (Grintz.) Rech. fil.) in Turkey. Subsp. haradjianii is endemic and very common. In this study, Astrantia specimens were collected from different localities and investigated for morphological and anatomical...

In September 1969, the Florida barge spilled 700,000 L of No. 2 fuel oil into the salt marsh sediments of Wild Harbor, MA. Today a substantial amount, approximately 100 kg, of moderately degraded petroleum remains within the sediment and along eroding creek banks. The ribbed mussels, Geukensia demissa, which inhabit the salt marsh creek bank, are exposed to the spilled oil. Examination of short...

Objective We present an approach for detecting mitochondria in electron microscopy images of brain tissue and demonstrate it on the rat neuropil. This would enable the study of statistics of mitochondria and their location relative to other structures such as cell boundaries, vesicles and synapses. Neural tissue from the Lateral part of the rat's brain was cut into 50nm slices and photographed ...
