Bone’s fracture resistance relies on its material properties, which can change with aging and disease. The material properties may be altered by changes in bone’s organic matrix via biochemical modifications of collagen, such as non-enzymatic glycation (NEG), which produces crosslinks known as advanced glycation end-products (AGEs). Alterations may also arise from the non-collagenous protein co...

Introduction: Nanoparticles have several exciting applications in various fields of biomedicine. It has been found that among different classes of nanoparticles core/shell is most promising for field of nano-medical imaging and therapy due to their distinct advantages. The core/shell type nanoparticles can be generally comprising of two nanoparticles one act as a core (inner ma...

Non thermal plasma (NTP) reactors packed with non-catalytic or catalytic packing material have been widely used for the abatement of volatile organic compounds such as toluene, benzene, etc. Packed bed reactors are single stage reactors where the packing material is placed directly in the plasma discharge region. The presence of packing material can alter the physical (such as discharge charact...

In this study, the effect of MQW structures adopting inorganic material (sodium fluoride) has been demonstrated. Brightness, current efficiency was significantly enhanced with a NaF/NPB MQW structure being inserted. The admittance spectroscopy was measured to explain the different mechanism of reducing hole between organic/organic inorganic/organic MQW

objective: soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. so, this research has been done for achieving this purpose. methods: this...

Changes in physical and chemical characteristics of an organic waste (tomato crop waste) throughout composting (COM), vermicomposting (VER) and the combination of both processes (C+V) were assessed at five selected stages. COM consisted of a combination of the static Rutgers system with forced aeration and pile turning. For VER Eisenia worms were fed with the raw material. For C+V pre-composted...

There has been significant interest in the role that carbonaceous aerosols play as radiatively important species in climate and visibility reduction, as potential toxic agents to human health in urban regions, and as surfaces that can catalyze atmospheric chemical reactions. These aerosols are a mixture of primary organic matter that is emitted from a number of sources, including mobile sources...

Thin films of organic material produced in a dusty plasma in N2–CH4 mixtures are deposited on silicon substrates. The real (n) and imaginary (k) parts of the complex refractive index are determined using the spectroscopic ellipsometry technique in the 370-1000 nm wavelength range. The optical index depend strongly on the methane concentrations: k values decreases with initial CH4 concentration,...

This retrospective and descriptive study with a quantitative design aimed to evaluate occupational accidents with exposure to biological material, as well as the profile of workers, based on reporting forms sent to the Regional Reference Center of Occupational Health in Florianópolis/SC. Data collection was carried out through a survey of 118 reporting forms in 2007. Data were analyzed electron...

Biomaterials containing components similar to the native biological tissue would have benefits as an implantable scaffold material. To obtain such biomimetic materials, cells may be great contributors because of their crucial roles in synthetic organics. In addition, the synthesized organics-especially those derived from osteogenic differentiated cells-become a place where mineral crystals nucl...
