A numerical assessment of the heterogeneous effects of innovative shroud profiles for horizontal axis wind turbine.

Wind turbine control is critical in power generation from wind, thus assuring great efficiency and cost-effectiveness. This has been a subject of intense research, and its advancements are critical to developing even better and efficient wind turbines. This research looks at several passive flow control mechanisms for horizontal wind turbines.

A comparative examination of the aerodynamic performance of various seashell-shaped wind turbines.

The seashell-shaped wind turbine (spiral wind turbine SWT), a brand-new form of the horizontal axis wind turbine, is intended for metropolitan use. SWTs have the additional advantage of being installed anywhere without considering their surroundings, as they do not need to be located facing the wind direction. The present work introduces various designs of the rotor of the seashell wind turbine to achieve the greatest performance.

Effect of Absenteeism on Student's Performance in Different Components of Examinations - A Comparison of Online Verses Offline Teaching.

Background: The In online learning, more responsibility is shifted towards students in learning according to their needs. However there is a need to assess which component of teaching can be shifted online for future hybrid teachings.

Objective: This study aims to compare the students' performance in difference components of the exams and compare them in online vs offline.

Video-assisted thoracoscopic thymectomy for non-thymomatous myasthenia gravis: a right-sided or left-sided approach?

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was in [patients undergoing video-assisted thoracoscopic thymectomy for myasthenia gravis (MG)] is a [left-sided approach] superior to a [right-sided approach] in terms of [clinical outcome]? Two hundred and fifty-nine papers were found using the reported search. In looking at both procedures, we selected studies with a sizeable number of patients performing or studying both procedures and comparing their outcome.

SPONDYLODISCITIS DESEASE EVALUATION IN PATIENTS WITH SERONEGATIVESPONDYLOARTHROPATHIES.

Spondylodiscitis (SD) is a destructive discovertebral lesion which is uncommon, but well recognised as a complication of Ankylosing Spondylitis (AS), and also called the Andersson lesion. This prospective study described 24 cases of AS, 12 of them with SD with variable clinical presentation and radiological appearance (SD). Two had multiple lesions, in one patient spondylodiscitis was the presenting symptom of AS.

Combined Vascular and Orthopaedic Approach for a Pseudotumor Causing Deep Vein Thrombosis after Metal-on-Metal Hip Resurfacing Arthroplasty.

Introduction. Metal-on-metal (MoM) hip resurfacings have been associated with a variety of complications resulting from adverse reaction to metal debris. Pseudotumors have rarely been reported to cause deep venous thrombosis (DVT).
