Periodontal diseases, including gingivitis and periodontitis, are a global oral health problem.Porphyromonas gingivalis, a key pathogen involved in the onset big girls woven tee of periodontitis, is able to colonize the subgingival epithelium and invade the underlying connective tissue due to the contribution of cysteine proteases known as gingipai
Graphene Twin Loft Bed is regarded as a promising solid-state lubricant; however, its frictional properties under varying conditions remains limited.In this study, atomic force microscopy (AFM) is used to measure the frictional behavior of graphene supported on four different substrates.It is found that for hard substrates, roughness reduces the in
The price of fossil fuel accompanied by an increasing awareness of environmental problems associated with global warming, resulted in an upsurge of scientific activity to identify and develop environmentally friendly sources of electrical power.In this sense, direct energy conversion by thermoelectric devices using residual heat as heating source,
Today data is not only constrained to text format; it has been expanded to multi-media data as well.As compared to audio and images, video data needs an attention, due to ever increasing size of videos and their massive storage size.Size of video data is increasing due to introduction of numerous video Triac applications.The video data mining faces
