INTRODUCTION Physiological cardiac hypertrophy and dilation are common findings in heavy physical load activity. We carried out this study to investigate the relationship between construction work and cardiac parameters adaptations, by comparing healthy masons to office workers on heart ultrasound. METHODS The study was carried out on, 50 construction workers and 50 office workers matched for...

A 65-year-old man, actively engaged in farming activities, with a 90 pack-year smoking history, presented with a painless ulcerated lesion on the left labial commissure. He was referred to our department because of suspected neoplasia. The lesion progressed slowly through a 2-year period. Oral examination revealed an extensive ulcer, although flat and with no signs of orbicularis oris muscle in...

Through this research, we measure the direct tensile strength of three important southeast Australian heritage dimension stones and compare results with published values. The are Sydney Sandstone, Victorian Bluestone South Black Granite. This information is crucial for stone masons when they selecting cutting construction projects, as need to ensure that use repair will be strong enough withsta...

This project is ongoing research focused on finding a method of reconstruction, using computational devices to build, represent and evaluate Palladio’s un-built villas in three-dimensions. The first of The Four Books of Architecture contains text and images explaining Palladio’s design and construction systems in the form of rules. These rules were written for masons and craftsmen of the 16th c...

This exploratory study characterizes two transdisciplinary humancentered design approaches for creating novel products or services for poverty alleviation. Transdisciplinary design involves the integrated use of tools, techniques, and methods from multiple disciplines in one holistic process. The term discipline includes academic fields of study that are taught in universities, as well as speci...

This study assessed the effectiveness of a commercially available local exhaust ventilation (LEV) system for controlling respirable dust and crystalline silica exposures during concrete grinding activities. Surface grinding was conducted at six commercial building construction sites in Seattle, WA, by cement masons. Time-integrated filter samples and direct reading respirable dust concentration...

BACKGROUND Occupational exposure to silica dust occurs in many workplaces and is well known to cause silicosis. However, the link between silica exposure, silicosis and other diseases is still disputed. AIMS To evaluate cause-specific mortality in a cohort of Italian silicotics. METHODS The cohort included 2034 male compensated for silicosis between 1943 and 1986, alive on 1 January 1987 an...

UNLABELLED Facial trauma has presented an increasing occurrence in the last four decades, due especially to the growth of accidents with automobiles as well as to the urban violence. Both of which continue being the main cause of such traumas. AIM To evaluate the features of the population victim of facial trauma as to gender, age, occupation, origin, type of fracture and its cause. DESIGN ...

AIM To identify occupations with excess prevalence of osteoarthritis of the knee, hip, and hand in a nationwide survey and to compare occupations with and without excess prevalence with regard to biomechanical stresses and severity of osteoarthritis. METHODS Patients presenting with osteoarthritis of the knee, hip, or hand were recruited throughout France by their treating physician who colle...
