pre-implant disease is an inflammatory process that affects the surrounding tissues of a functional osseointegrated implant. it is usually the result of a disequilibrium between the micro-flora and the defense system. this case reports a 57-year-old man with unusual bone loss around dental implants. this was an unusual case of peri-implantitis that occurred only in the implants on one side of t...

Serpentine is formed during chemical transformation of ultrabasic magmatic rocks. The characteristics of serpenti ne soi l are its high Mg and low Ca contenI. Various factors have lead to the formation of specific serpentine flora and vegetation. In the serpentine flora both basophi10us and acidophilous plant species are present, and a small number of families and often genera predominate. Most...

Understanding of soil processes is essential for addressing the global issues of food security, disease transmission and climate change. However, techniques for observing soil biology are lacking. We present a heterogeneous, porous, transparent substrate for in situ 3D imaging of living plants and root-associated microorganisms using particles of the transparent polymer, Nafion, and a solution ...

For many natural and agricultural landscapes, vegetation partially covers the ground surface, resulting in significant variations in soil heat flux between interspace areas and underneath vegetation. This is particularly apparent in arid and semiarid regions where vegetation cover is low and clustered or ‘clumped’ with large areas of exposed soil. Surface heterogeneity presents significant chal...

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...

The influence of soil pH was evaluated on the abundance and generic diversity of cyanobacteria in soil samples collected from diverse rice soil ecologies of India. Qualitative and quantitative studies of the 52 soil samples collected from nine agroecologies was carried out using enrichment, MPN (Most Probable Number) techniques and diversity indices were measured. A total of 166 forms, includin...

Transgenic crops, a new product of agricultural biotechnology has its own share of environmental risks and benefits. Present agricultural management practices and new ecosystems have their own impacts on the environment and further any additional negative effect of transgenic crops may mitigate their positive impacts as well as increase the background value of negative impacts due to new agricu...
