As industrial systems represent a complex socio-technical system, it is necessary to analyse the impact of manageroperator-machine interaction on safety, as categories contextual factors. However, modern scientific literature indicates insufficient research this topic. This paper has an aim empirically behavioural style and transport mining machines operators' attitudes in safety climate contex...
Foredunes are efficient natural coastal defenses acting as protective barriers during storm events. They also have the capacity to be an ecosystem hosting significant biodiversity. The economic development and/or recreational use of foredune commonly results in a modification functioning and concomitant mixing anthropogenic processes. While impact human interventions on short term evolution dun...
The nexus of advocacy and science has been a recurring discussion theme since the earliest days of the Society for Conservation Biology. When Michael Soulé defined conservation as a “mission-oriented discipline,” he succinctly captured the issue. He and others have asked whether biologists on a mission to save ecosystems, ecological communities, species, and populations can provide the value-fr...
Latecomer companies are those that have been slow in adopting modern enterprise systems. A key feature of latecomer companies is that they have been automating operations and digitizing administrative processes but their efforts have generally been local and segmented, which limits information exchange and makes resource coordination across business units difficult. As a result, slack resources...
Mosul has been freed from the clutches of terrorists since 2018, yet city remains in serious need reconstruction and redevelopment. The current study attempts to determine whether fragments damaged structures can be used old Mosul, as well its economic, cultural, civilizational feasibility. Old-heritage materials have categorized into four primary categories, which avoid confusion while disposi...
Introduction. In Kazakhstan in present time there is a large number of earthmoving works, which leads to an increase the demand for earthmoving-transport machines (ETM), particular bulldozers different types. various industries and construction projects, fleet foreign-made ETM operated constantly updated, including CIS countries (Russia, Belarus, Ukraine, etc.) type-sizes. So at sites, roads ra...
ALTHOUGH MANY STUDIES HAVE SHOWN an association between operating heavy construction equipment and symptoms of musculoskeletal disorders (MSDs), little research has been performed that systematically characterizes the exposure of operating engineers to ergonomic hazards. This study evaluated: 1) vibration at the seat/operator interface; 2) transmissibility of vibration in the Z-axis; 3) psy-cho...
C onstruction is of prime economic significance to many industry sectors. Intense competition, shortages of skilled labor, and technological advances are forcing rapid change in the construction industry, thus motivating construction automation [1]. Earthmoving machines, such as bulldozers, wheel loaders, excavators, scrapers, and graders, are common in construction. Excavationbased operations ...
Asbestos-containing brake linings were used in heavy-duty construction equipment such as tractors, backhoes, and bulldozers prior to the 1980s. While several published studies have evaluated exposures to mechanics during brake repair work, most have focused on automobiles and light trucks, not on heavy agricultural or construction vehicles. The purpose of this study is to characterize the airbo...
