We evaluated four commercial transport systems with a standardized inoculum of clinical isolates of N. gonorrhoeae (NG), and assessed survival after holding for up to 48 hours at both ambient and refrigeration temperatures. Suspensions of clinical isolates of NG were standardized and adsorbed onto four transport swab types: Culturette EZ (Becton Dickinson [BD], Cockeysville, MD, USA); Culturesw...

The genus Annona is confined almost entirely to tropical and subtropical America and the Caribbean region (Safford 1914). Edible species include Annona muricata L. (soursop), A. squamosa L. (sugar apple), A. cherimola Mill. (cherimoya), and A. reticulata L. (custard apple). Each geographical region has its own distinctive pest fauna, composed of indigenous and introduced species (Bennett & Alam...

The present study considers of the water and air flow and Micro-Bubble production inside the venturi tube, by the use of dimensional analysis. Numerical analysis of Micro-Bubble creation in venturi tube requires fast computers and large amounts of storage space. Up to now, there has been no numerical analysis concerning Micro-Bubble creation and all other existing studies are experimental. To s...

A "cannot-ventilate, cannot-intubate" situation is critical. In difficult airway management, transtracheal jet ventilation (TTJV) has been recommended as an invasive procedure, but specialized equipment is required. However, the influence of upper airway resistance (UAR) during TTJV has not been clarified. The aim of this study was to compare TTJV using a manual jet ventilator (MJV) and the oxy...

venturi flumes are measurement structures commonly used in water systems to measure the flow discharge. some of them are not well installed or present some geometrical defects. the objective of this study is to investigate the hydraulic influence of a number of typical wrong installations and geometrical defects of long-throated venturi flumes: significant positive or adverse slopes, humps and ...

The main function of a water supply and storm sewer pipe network is to properly maintain planned flow rates, pressure, depth within pipes. This can be simulated with numerical analysis model. In general, model experiments are required verify correct the accuracy models, but due nature complex facilities, scale related studies very limited. Therefore, this study aimed develop kit capable general...
