Improving the indoor / outdoor ratio of (ultra)fine particles in a school

Buildings located close to busy roads, industry or stock farms, are of risk of increased indoor particle concentrations, which negatively impacts the health of the building occupants. In order to reduce the exposure of the building occupants, it is important to take measures to reduce the concentration of particulate matter indoors. Solutions...

Vertical greenery systems: From plants to trees with self-growing interconnections

The integration of buildings into vegetation has become a necessity in many metropolitan areas of the world today. It expands the potential of vertical and horizontal, exterior and interior, exposed and enclosed spaces in a building that can be used to accommodate plants. Green infrastructures have benefits both on urban and building scales....

Nature’s Particulate Matter with and without Charge and Travelling

Natures and anthropogenic particulates can travel long distances on wind flows, but negative electrical charge due to friction can increase dispersion. Models for calculations of distance travelling of biological particulate matter with and without charge are never been calculated in a theoretical approach. Nor do we realize the fact that we can...

Climate Shifts and the Role of Nano Structured Particles in the Atmosphere

A global net sum equilibrium in heat exchange is a fact and thus a global climate change doesn’t exist, but climate shifts in climate cells, especially in the northern temperate cell, do. The global climate has been ever since homeostatic, and has recuperated far huger climate impacts in the past. Current climate models need a drastically...

Altered wall shear stresses in embryonic chicken outflow tract due to homocysteine exposure

The embryonic heart is already beating before cardiac morphogenesis is complete. Therefore, the effect of blood flow on cardiogenesis has been subject of many studies. Shear stress, acting on the endocardial cells, has been shown to alter the expression of shear-responsive genes implicated in heart development. The congenital heart defects (CHDs...

Biomaterials

The metabolic pathways of living organisms produce biomaterials. Hence, in principle biomaterials are fully sustainable. This does not mean that their processing and application have no impact on the environment, e.g. the recycling of natural rubber remains a problem. Biomaterials are applied in a wide range of consumer products, varying from...

On the effectiveness of mangroves in attenuating cyclone induced waves

A study of the effectiveness of mangroves in attenuating cyclone- induced waves was done using the SWAN 40.81 numerical model. Hydraulic parameters during extreme events and local mangrove vegetation parameters were estimated for the Kanika Sands mangrove island near the upcoming Dhamra Port in Orissa, India. Simplified generic analyses were...
