Surface-Piercing Propellers (SPPs) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. Unlike the submerged propellers, theoretical methods have no significant application on simulation of SPPsbecause of problems related to modeling of these propeller...

This study aimed to develop optimum information systems to improve physical function after carpal tunnel release. The t-test was done to compare the differences of physical function after carpal tunnel surgery before and after information system application. As a result, for carpal tunnel syndrome, the carpal status in subjects who have suffered from paresthesia decreased after the system appli...

This paper provides an Analog Behavioral Model (ABM) in PSpice of a tunnel diode The PSpice parameters are implemented as separate parameterized blocks constructed from SPICE (ABM) controlled sources and extracted through experiment. A tunnel diode based oscillator is also proposed and simulated using circuit analysis software. The behavior of the tunnel diode is simulated and compared to the m...

Ulnar neuropathy at or distal to the wrist, the so-called ulnar tunnel syndrome, is an uncommon but well-described condition. However, diagnosis of ulnar tunnel syndrome can be difficult. Paresthesias may be nonspecific or related to coexisting pathologies, such as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, C8-T1 radiculopathy, or peripheral neuropathy, which mak...

BACKGROUND Although controversial, recent studies have demonstrated advantages of sonographic techniques in the diagnosis of carpal tunnel syndrome (CTS). The purpose of this study was to assess the utility of median nerve ultrasonography in the diagnosis of CTS in Iranian patients. METHODS Ninety patents with clinically suspected CTS were studied. Based on gold standard electromyography/nerv...

BACKGROUND Coracoclavicular (CC) ligament reconstruction with semitendinosus tendon (ST) grafts has become more popular and has achieved relatively good results; however optimal reconstruction technique, single-tunnel or two-tunnel, still remains controversial. This paper is to compare the clinical and radiographic data of allogenous ST grafting with single- or two-tunnel reconstruction techniq...

We used a motorized treadmill to determine the endurance (from 4.2 to 5.6cm s") and burst speed of five Coluber constrictor Linnaeus performing concertina locomotion in tunnels 3, 5 and 7cm wide. The snakes had greatest average endurance at 4.2cms" within the 5cm wide tunnel (80min), and the average endurance of snakes moving in the 3 cm tunnel (24 min) was significantly lower than that observe...

The influence of anatomical or nonanatomical femoral tunnel position on tunnel widening and clinical outcomes in patients undergoing anterior cruciate ligament (ACL) reconstruction is not fully understood. This retrospective study examined the influence of tunnel width and placement on anterior knee stability and clinical outcomes after ACL reconstruction using the AperFix System (Cayenne Medic...

Background: Cubital tunnel syndrome, a neuropathy of ulnar nerve, is the second most common entrapping syndrome in the upper limb surpassing carpal tunnel syndrome. This syndrome arises from a high pressure decompressing the nerve for a long time. Patients with cubital tunnel syndrome show numbness in the ring and small fingers. The aim of this study was to evaluate the etiology of cubital tunn...
