An experimental investigation was conducted to assess the effectiveness of a suction flow control method for vortex-induced vibration (VIV) suppression. The flow control method uses a limited number of isolated suction holes to manipulate the vortex shedding in the wake behind a circular cylinder in order to reduce the unsteadiness of the dynamic wind loads acting on the cylinder. The experimen...

BACKGROUND/AIM To analyze the influence of intraoperative cervical dilatation and curettage during elective Caesarean section (CS) on maternal morbidity. PATIENTS AND METHODS A total of 1,003 elective CS were retrospectively evaluated. Primary outcome measure was the influence of cervical dilatation and curettage on postpartum haemorrhage (PPH). Several subgroup analyses were performed and a ...

OBJECTIVE The best treatment of aneurysmal bone cyst (ABC) is still unclear. This study aimed to evaluate the usefulness of extended curettage and ethanol as an adjuvant to reduce local recurrence of ABCs. METHODS Retrospectively, 68 cases treated for primary and secondary ABCs caused by benign tumors from 2003 to 2013 were enrolled to a follow-up visit between one to ten years after the surg...

Ornithodoros rostratus is an argasid tick and its importance is based on its hematophagy and the resulting transmission of pathogens such as Rickettsia rickettsii and Coxiella burnetii to its vertebrate hosts. In the face of a lack of physiological studies related to hematophagy in argasid ticks, this paper aims to identify and characterize the events that occur throughout the feeding by O. ros...

Rechecking the position of the nasogastric tube after oropharyngeal suction is not common practice. Our patient deteriorated after oropharyngeal suction was performed, whilst nasogastric feeding continued. We suggest that nasogastric feeding should be stopped during oropharyngeal suction and the tube position should be checked every time an oropharyngeal suction is performed.

I, Bedok South Road, Singapore 1646 This study attempts to qualitatively quanti:(y the thermal design aspects of the suction tube of a hermetic refrigeration compressor with high shell pressure configuration. The effects on heat transfer and fluid flow which affect the design dimensions and material selection of the suction tube will be shown and discussed. Results obtained suggested that the t...

A numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. The continuity and momentum equations were solved first, assuming the wall Reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. The results show that at constant inlet and...

Objective To evaluate the accuracy of transvaginal ultrasonography, hysteroscopy and uterine curettage in the diagnosis of endometrial polyp, submucous myoma and endometrial hyperplasia, using as gold standard the histopathological analysis of biopsy samples obtained during hysteroscopy or uterine curettage. Methods Cross-sectional study performed at the Hospital Universitário de Brasília (HUB)...
