In the past few decades, the retrospective analysis of the possible etiological factors responsible for Aggressive periodontitis has magnified to its brink. The necessity lies in segregating the evidences and acknowledging their potential role in the pathogenesis of Aggressive periodontitis. In this paper, an attempt has been made to summarize recent views on various etiological agents involved in the pathogenesis and progression of aggressive forms of periodontitis. Data was identified by searches of the Medline and Pubmed. Articles published in English were selected and most up-to-date or relevant references were chosen.

Periodontal disease is chronic inflammation that leads to alveolar bone loss and destruction of periodontal ligament.The challenges in regenerative periodontal therapy lie in the ability to induce the regeneration of a complex periodontal apparatus consisting of bone, cementum, and periodontal ligament. Though immense advancement has occurred in past few years in periodontal therapy, a complete regeneration of the damaged periodontium still remains a distant goal.A stem cell is a cell that has the ability to divide (self-replicate) for indefinite periods, often throughout the life of an organism. It has been proposed that the bone marrow mesenchymal stem cells (BMMSCs) are very likely to be another cell source of physiological repair of periodontal tissues.This article is an overview of the basics of stem cell biology and their potential nature as regenerative cells of periodontium.

In this configuration, one shunt voltage-source converter (shunt VSC) and two or more series VSCs exist. The system can be applied to adjacent feeders to compensate for supply-voltage and load current imperfections on the main feeder and full compensation of supply voltage imperfections on the other feeders. In this setup configuration, all converters are connected back to back on the dc side and share a common dc-link capacitor. Therefore, power can be transferred from one feeder to adjacent feeders to compensate for sag/swell and interruption. A power system consist of two three phase three wire 380V (rms, L-L), is designed and simulated in MATLAB Simulink and compared Power transfer between two adjacent feeders and Compensation for interruptions.

Lamination cannot be changed frequently because it needs tool (die) development, for designing of new laminations the time required and cost increases enormously which is not acceptable to the manufacturers. At an instant very less information/ data is available about the fact that a synchronous generator can also causes harmonics at the time of generation of EMF, So it becomes paramount to deal with this important equipment as far as harmonics and related losses. Considering the harmonics present in the machine which, is mainly due to unequal distribution of field fluxes in the air gap. Many of researchers studies have been addressed that Synchronous machines are also source of harmonic currents on two counts: the frequency conversion effect and the non-linear characteristic due to magnetic saturation. Therefore we concentrated our investigation work on the distribution type of winding only. Considering the harmonic present in the machine, our concentration was on pitch factor.

For industrial power applications, particularly in the sugar, pulp, oil and gas sector, cogeneration or combined heat and power (CHP) provides an interesting technology for maximizing energy utilization and minimizing emissions. Criticisms of environmental compliant power systems usually focus on the cost of development, manufacturing and operation. However, few decisions on whether a system meets acceptable specification can be made until the power system is fully understood and optimized.
