Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...

recurrent spontaneous rupture of the urinary bladder has rarely been reported in english articles. this condition may be difficult to diagnosis before a laparotomy due to acute peritonitis. herein we describe a case of recurrent spontaneous rupture of the bladder in a 39-year-old woman with human t-lymphotropic virus type 1 (htlv-1) -associated myelopathy/topical spastic paraparesis (ham/tsp).

Spontaneous bilateral mode II shear ruptures were nucleated on faults in photoelastic Homalite plates loaded in uniaxial compression. Rupture velocities were measured and the interaction between the rupture front and short fault branches was observed using high-speed digital photography. Fault branches were formed by machining slits of varying lengths that intersected the fault plane over a ran...

BACKGROUND AND PURPOSE Rupture risk assessment for intracranial aneurysms remains challenging, and risk factors, including wall shear stress, are discussed controversially. The primary purpose of the presented challenge was to determine how consistently aneurysm rupture status and rupture site could be identified on the basis of computational fluid dynamics. MATERIALS AND METHODS Two geometri...

BACKGROUND Rupture is an important complication of breast implants. Before cohesive gel silicone implants, rupture rates of both saline and silicone breast implants were over 10%. Through an analysis of ruptured implants, we can determine the various factors related to ruptured implants. METHODS We performed a retrospective review of 72 implants that were removed for implant rupture between 2...

OBJECTIVES The aim of this study was to identify factors causing rupture recurrence after surgical repair of postinfarction ventricular septal rupture and to evaluate the indication for reoperation. PATIENTS Recurrence of rupture was analysed in 25 out of a series of 109 patients who underwent surgical repair for postinfarction ventricular septal rupture between 1980 and 1992 in our instituti...

A 4-day-old Holstein bull calf with considerable oedema of the belly (water belly) was referred to theVeterinary Teaching Hospital of the School of Veterinary Medicine, Shiraz University. The owner did notobserve any urination since birth. Rupture of the urethra was suspected. Perineal urethrotomy was performed. Subsequently, catheterization of urethra revealed the obstruction near the external...

Various complications of hydatid cyst have been recognized to date. We have encountered one such complication-rupture of hydatid cyst to the duodenum­ leading to upper gastrointestinal bleeding in a 40 year old male, who referred with severe right upper quadrant (RUQ) pain and gastrointestinal bleeding of a few hours' duration. Laparotomy revealed a cyst (7 x 15 cm) in the left lobe of the ...

While gender-based differences in knee joint anatomies/laxities are well documented, the potential for them to precipitate gender-dimorphic ACL loading and resultant injury risk has not been considered. To this end, we generated gender-specific models of ACL strain as a function of any six degrees of freedom (6DOF) knee joint load state via a combined cadaveric and analytical approach. Continuo...

Background: This study aimed to introduce a modified technique for minimally invasive Achilles tendon (AT) rupture repairusing gift box sutures. The preliminary clinical and functional outcomes were investigated among a number of patients.Methods: In a consecutive case series study, 24 patients with acute AT rupture underwent modified minimally invasiveAT repair using two mini...
