Heavy movable bridges have different design, operation and maintenance characteristics compared to fixed bridges. This is mainly due to the complex interaction between their structural, mechanical and electrical systems. Movable bridges are viable options in certain terrain conditions and their unique operation provides versatility. At the same time, their intricate interrelation also produces ...

general kind of encroachment of river is constructing a bridge on it. purpose of encroachment of river is occupation part of river and flood plain for constructing bridge. often being economical of bridge innovation affirmated that most of encroachment take place to river and flood plain, which this encroachment can be in form of embankment in flood plain of river or into the main bed of river ...

We investigated the effects of aging on Drosophila melanogaster indirect flight muscle from the whole organism to the actomyosin cross-bridge. Median-aged (49-day-old) flies were flight impaired, had normal myofilament number and packing, barely longer sarcomeres, and slight mitochondrial deterioration compared with young (3-day-old) flies. Old (56-day-old) flies were unable to beat their wings...

BACKGROUND Filler injection for face augmentation is a common cosmetic procedure in the last decades, in our case report we describe long-term outcomes of a devastating complication of ophthalmic artery emboli following Calcium Hydroxylapatite filler injection to the nose bridge. CASE PRESENTATION A healthy 24-year-old women received a Calcium Hydroxylapatite filler injection to her nose brid...

Accounting for the effect of rebar depth variation is one of the most important and challenging tasks to accurately assess the condition of reinforced concrete elements using ground penetrating radar (GPR) technique. In current practices, this task is performed on the individual basis, as for each bridge deck a unique depth correction model is derived from the GPR data collected on it. It is fo...

BACKGROUND Heart transplantation is considered the gold standard therapy for the advanced heart failure, but donor shortage, especially in pediatric patients, is the main limitation for this procedure, so most sick patients die while waiting for the procedure. OBJECTIVE To evaluate the use of short-term circulatory support as a bridge to transplantation in end-stage cardiomyopathy. METHODS ...

Since large parts of western countries' infrastructure have been erected in the early 1960's, many infrastructure buildings such as concrete bridges are now entering a critical age, where the need for continuous inspection and reconditioning is becoming apparent. Facing these challenges, many national highway authorities have developed computer systems that allow for the management of data coll...

The hangers of a suspension bridge is one of the most important stressed members, the thorough research of the deterioration during operation period and the security analysis after the degeneration of hangers is essential. This is the basis of the strategy of preventive maintenance of suspension bridges. Firstly, the paper studies the four stages of degradation mechanisms of sling and calculati...

Handling Editor: Stephanie Castro In this study, we develop and examine a model of leaders' impression management during organizational decline by elaborating on the roles of publicity, image concerns, and incentive compensation. We propose that the publicity of decline is an important antecedent of leaders' impression management during decline. We also examine how leaders' image concerns media...

Abstract Bridges all over the world are vulnerable to severe deterioration agents meanwhile their maintenance budgets being tightened. This state of affairs necessitates establishment an autonomous model predict performance condition bridges. research paper explores implementation a set intelligent data driven models analyze future ratings bridge decks. These comprise support vector machines, G...
