The patellofemoral joint is intrinsically unstable because the tibial tubercle lies lateral to the long axis of the femur and the quadriceps muscle, and the patella is therefore subject to a laterally directed force. This apparent ‘design fault’ is minimised by the resistance of the lateral lip of the trochlea to lateral movement of the patella during flexion (Brattström 1964). In full extensio...

Simulation analyses for in-situ cyclic loading tests in cohesive soil were conducted to indicate that finite element models considering nonlinearity of material , pile-soil separation and a loosened layer valid evaluating lateral resistance steel pipe piles with wings driven by rotational penetration. The results analytical studies demonstrated pile head load approached without when displacemen...

This paper studies the effect of loading eccentricity and pile spacing on ultimate lateral soil resistance twin-piles using finite element limit analysis analytical upper bound plasticity methods. Two kinematic mechanisms corresponding to failure modes produced by advanced simulations are postulated with different cases. Comparisons have shown excellent agreements between two approaches. A seri...

BACKGROUND Nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. This study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. METHODS Fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. Objective...

This paper presents a compact model of lateral double diffused MOS (LDMOS) transistor having small size and got good result with different characteristics. This model is designed with ATLAS SILVACO and get better simulations of breakdown voltage, on resistance etc. comparing with reference LDMOS. We have designed this device with channel 0.3 μm length and gate 0.75 μm length.

Advanced bipolar transistors play a vital role in RF/Microwave applications. But they need to satisfy stringent demands on device performance parameters such as β, gm, and fT. Many of the bipolar technologies developed to meet these demands are vertical structures and suffer from many non−ideal effects at high collector current densities. In the present work, to enhance the performance limits o...

One key issue for high voltage CMOS structures is the proper design of the output driver devices, which are usually lateral DMOS transistors (LDMOST). We present an analysis of a LDMOST and an ALDMOST (accumulation LDMOST) with respect to ON-resistance, punch-through and avalanche breakdown.

Amyotrophic lateral sclerosis is a devastating neurodegenerative disorder characterized by the progressive loss of spinal motor neurons. While the aetiological mechanisms underlying the disease remain poorly understood, oxidative stress is a central component of amyotrophic lateral sclerosis and contributes to motor neuron injury. Recently, oxidation resistance 1 (OXR1) has emerged as a critica...

Acute patellar dislocation or subluxation is a common cause for knee injuries in the United States and accounts for 2% to 3% of all injuries. Up to 49% of patients will have recurrent subluxations or dislocations. Importance of both soft tissue (predominantly, the medial patellofemoral ligament, MPFL, which is responsible for 60% of the resistance to lateral dislocation) and bony constraint of ...

We report here a rare case of lateral ectopia of thyroid without orthotopic thyroid tissue in an Indian teenager, who was referred to our department for a thyroid scintigraphy. Technetium Pertechnetate (99mTcO4- ) scan showed uptake in laterally placed soft tissue structure along with functioning thyroid tissue in high anterior midline neck region in line with thyroglossal...
