Axons are the thin and long extensions of neuronal cells that snake away from cell body. in our nervous system like bridges spanning distances to bring information one nerve another. However, axons alive need nutrients energy survive. degenerate if run out. This results devastating symptoms many conditions called neurodegenerative diseases. Scientists must understand why how prevent or delay it...

Demolition and construction waste are among the topics that focus by many researchers. The ‎methods of reuse materials must reduce economic environmental pressure their ‎presence in various regions. Before 2014, city Mosul contained relatively small quantities ‎demolition debris, especially concrete rubble, asphalt materials, bricks (they formed ‎approximately 80% demolition debris). These incr...

The roles of both the data collection method (including proper classification) and the behavior of workers on the generation of demolition waste (DW) are important. By analyzing the effect of the data collection method used to estimate DW, and by investigating how workers' behavior can affect the total amount of DW generated during an actual demolition process, it was possible to identify strat...

Demolition of older housing for urban redevelopment purposes benefits communities by removing housing with lead paint and dust hazards and by creating spaces for lead paint-free housing and other community resources. This study was conducted to assess changes, if any, in ambient dust lead levels associated with demolition of blocks of older lead-containing row houses in Baltimore, Maryland (USA...

Neutralization of landmines is dangerous and complicated work. For Humanitarian Demining, the most common neutralization method is demolition using small explosive charges. Although common practice, demolition has several disadvantages. Deminers need non-explosive mine neutralization technologies that are safer, more reliable and less expensive. To meet this need, several innovative non-explosi...

Whilst vehicular and industrial contributions to the airborne particulate budget are well explored, the input due to building demolition is relatively unknown. Air quality is of importance to human health, and it is well known that composition of airborne particles can have a significant influence on both chronic and acute health effects. Road dust (RD) was collected before and after the demoli...

OBJECTIVE To estimate standardised hospitalisation ratios (SHR) for chronic lower respiratory diseases among demolition and cement workers in Denmark, 1995-2009. DESIGN This is a population-based register study on data from 'the Occupational Hospitalisation Register'. SHR of chronic obstructive pulmonary disease (COPD) was calculated for both demolition and cement workers. SETTINGS Register...

BACKGROUND Building demolition can lead to emission of dust into the environment. Exposure to silica dust may be considered as an important hazard in these sites. The objectives of this research were to determine the amount of workers' exposure to crystalline silica dust and assess the relative risk of silicosis and the excess lifetime risk of mortality from lung cancer in demolition workers. ...

Palestinians in the Gaza Strip are exposed to variety of traumatic events including witnessing killing of friends, bombardment, and home demolition. Previous studies in the area showed that exposure to traumatic events lead to psychological reactions including PTSD, depression, and anxiety [1-4]. Loss of homes due to home demolition leads to reactions in children and adults. Previous study of c...
