Since 1991 ten patients, 9 male and 1 female, with aortic arch aneurysm underwent surgical therapy with trapdoor thoracotomy. The mean age was 67.4 +/- 9.1 (standard deviation) years at operation. In addition to the aortic arch repair, we also performed seven descending aortic replacements. We performed one partial arch replacement, one total arch replacement, and one aneurysmorrhaphy and wrapp...

Background The foot arch serves important functions in regard to shock absorption and the action of walking. Simple and quantitative classification of foot arch types such as flat foot and high arch would be helpful in health support for the elderly. The present authors have developed a classification system for foot arch type showing high reliability using foot pressure distribution data [1,2]...

introduction: a study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. the aim of this study is to evaluate reliability and validity of dental measurement made on digi...

the aim of this paper is to explore conventional methods of teaching the arch-design studio withideas of sustainability and creativity as agents of change. if this is realised, it means the students of architecture canbe grounded in designing with sustainability and creativity ideas and can be professionals that design and build withideas of creativity and sustainability. so, there are real bui...

Arch extension of aortic dissection (AD) is reported to occur in 4-25% of patients presenting with acute type B AD. The DeBakey and Stanford classifications do not specifically account for this subset, however, recent studies have demonstrated that the prognosis of patients with arch extension in acute type B AD is virtually identical to that of others with type B AD. In this sense, it seems re...

Many single or multispan arch bridges are strengthened with the addition of some kind of structural support between adjacent arches of multispan or beside the arch barrel of a single span to increase the strength of the overall structure. It was traditionally formed by either placing loose rubble masonry blocks between the arches and beside the arches or using mortar or concrete to construct a ...

The possibility of using a nonlinear moving average (NMA) test as a test for ARCH is considered. A joint test of ARCH and NMA tests is derived. The asymptotic relative efficiency of the NMA test against ARCH is also computed, and is found to be equal to zero. The small sample properties of the tests are examined by some simulation experiments, along with the effects of additive outliers. Overal...

It is essential to select the optimum method of cerebral protection and operative technique for arch repair to improve the surgical outcome of arch aneurysm or dissection. Selective antegrade cerebral perfusion (SACP) is our current method of choice if required cerebral protection time exceeds 30 minutes. Moderate hypothermic two-arch vessel perfusion (innominate artery or right axillary artery...

The objectives of this study were to estimate the maxillary arch measurements, to assess the validity of Pont's & Korkhaus' Indices; to determine the relationship between maxillary arch form with head form; and to estimate the cephalic index (CI) of the study population. A cross-sectional study was conducted on 85 mature Malay students, 28 male students (32.98%), 57 females (67.02%) attending T...
