OBJECTIVES To investigate the work-related musculoskeletal symptoms among building construction workers. METHODS Total 389 apparently healthy, male volunteers were selected with mean age 34.56±8.33 years and a mean working duration in building construction as 5.76±2.68 years. Musculoskeletal complaints were recorded through a detailed clinical interview and comprehensive questionnaire. RESU...

A simulation model and a rigid body model are used to investigate twisting initiated during the take-off or contact phase. It is shown that it is possible to produce a full twist solely by building up angular momentum in the arms during the contact phase. This method is only half as effective as building up momentum in the whole body during contact. The introduction of twist into a somersault c...

Nature provides a wide range of inspiration for building mobile micromachines that can navigate through confined heterogenous environments and perform minimally invasive environmental and biomedical operations. For example, microstructures fabricated in the form of bacterial or eukaryotic flagella can act as artificial microswimmers. Due to limitations in their design and material properties, t...

factor analysis is one of the most advanced multivariate statistical techniques applying to attain a variety of scientific and research goals such as model-building, hypothesis-building lest validation, identifying subtests and development conditions in order to perform the other advanced methods as multiple regression and structural equation models. while there are difficulties and complexitie...

In search and optimisation applications, model building is largely manual. However, relationships binding variables and making up constraints may be automatically generated if a complete enough body of data is available. At present, at the level of most businesses such a body is not only available but

background: this was a cross-sectional study on the gender differences in weight-control behavior. the strategies used, weight status, weight satisfaction, and proportion of individuals attempting to lose weight among 233 government employees (104 men and 129 women) working in the federal government building in penang, malaysia, were assessed. methods: anthropometric indicators such as body mas...

dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

Building construction challenge, in recent years, is the reduction of social, economical and environmentalimpacts along with economical nature and increasing life quality, as here sustainable construction is important. Pre-fabrication and industrialization are referred as a solution of sustainable construction due to some of its main characteristics consisting of many sustainability aspects. Du...

The human body is made up of 37 trillion cells and billions of these die every single day. The body has special cells, called macrophages, which consume dying cells to prevent them from building up in your body. Macrophages are also able to eat any cell that is infected by a bacterium or virus. This helps your body to remain as healthy as possible. Sometimes, the macrophages are given the wrong...
