This paper presents Computational Fluid Dynamics (CFD) analysis of Pelton turbine of Khimti Hydropower in Nepal. The purpose of CFD analysis is to determine torque generated by the turbine and pressure distributions in bucket for further work on fatigue analysis. The CFD analysis is carried out on model size Pelton runner reduced at 1:3.5 scale to minimize computational cost and time. The operating conditions for model size runner is selected in accordance with IEC 60193 and IEC 1116. The paper describes the methods used for CFD analysis using ANSYS CFX software. 3 buckets are used to predict the flow behavior of complete Pelton turbine. k-ε and SST turbulence model with interphase transfer method as free surface and mixture model is compared in the paper. The pressure distribution is found maximum at bucket tip and runner Pitch Circle Diameter (PCD). The torque generated by the middle bucket is replicated over time to determine total torque generated by Pelton turbine.

Oral ranula is a retention cyst arising from the sublingual gland on the floor of the mouth as a result of ductal obstruction and fluid retention. There are various techniques to manage ranula in the literature. There is no doubt that excision of the offending sublingual gland will cure all ranulas. Still, some surgeons prefer to initially treat ranulas by marsupialization, perhaps because of the potential surgical complications when removing the sublingual gland, most notably injury to the lingual nerve, injury to Wharton’s duct with the possibility of stenosis leading to obstructive sialadenitis, and ductal laceration causing salivary leakage. This paper highlights a case report of ranula in the floor of the mouth which was about 2cm and has been successfully treated by marsupalization and low level laser therapy. (LLLT)
Proactive maintenance highlights the regular discovery and modification of original root circumstances that would then start equipment failure. In the instance of hydraulic systems, there are three without difficulty obvious warning sign that give prompt detection of original cause situations. These indications are irregular noise, slow operation and high fluid temperature.

These indications are irregular noise, slow operation and high fluid temperature. Hydraulic is a technology that is broadly operated these days in most heavy construction equipment. This technology is to a great extent useful for managing the purposes of this equipment, since it is a liquid that transfers inside a detained part of the equipment plus the high pressure made by this, transports the equipment in the preferred path. The hydraulic is typically preferential by the operators because of the wonderful quantity of strength that it produces, which aids those heavy construction equipment that requires force to carry out. Currently, the equipment which is operated at the construction sites
