Designing and detailing of scaffoldings
Construction is a vast field. It involves so many processes, stages, materials, and tools. Scaffolding is a temporary or movable structure made of wooden planks and metal poles, used by workmen while building, repairing, or cleaning the building, bridges and all other man-made structures. It is also called ‘staging’ or ‘scaffold’. Scaffolds are widely used on construction site to get access to heights and areas that would be otherwise difficult to get to or to reach. Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half-pipes, and art projects. Scaffold has to fulfill a diverse set of requirements: - creation of safe and productive working areas - providing access to working areas at higher levels - carrying area and/or point loads Scaffolding work is erecting, altering or dismantling a temporary structure erected to support a platform and from which a person or object could fall more than 4 meters from the platform or the structure. Scaffolding work must be undertaken by a person holding the appropriate class of high-risk work license. This definition applies whenever the term ‘scaffolding work’ is used in this Guide.

Findings of may be fossil remains at Lonar Crater, Buldhana District, Maharashtra, India
Two representative samples which seemed to be of wooded nature, found in the soil towards the northern side of the crater water body, were collected to study its nature regarding a layer of white color deposition on the woods of unknown component since the water level has decreased sharply, the surface feature has been exposed widely. To investigate the white layer component deposition seen on these dry wooded samples, XRF analysis carried out of dried wooded nature samples showed that the major content was P₂O₅ (Phosphorus Pentoxide) – 36.50 % and CaO (Calcium Oxide) – 55.500 %, with other components in minor quantities such as SiO₂, MgO, Al₂O₃, etc., such a high percentage of P₂O₅ and CaO in the wooded nature sample has never been observed before. A search was conducted which rock or mineral has such a composition and it came to be known that Apatite mineral of Calcium Phosphate nature has the same composition as that detected in the wooded sample and this Apatite mineral of Calcium Phosphate nature is related to fossils remains. The components found in dry wooded samples and composition of fossilized rock of apatite nature of calcium phosphate was found to be similar with respect to oxide and elemental composition. The wooded sample seemed to be of wood origin, was not of wooded nature but was found to be off fossil nature. It also came to be known that the white layer deposition was not due to CaO and P₂O₅, but the sample was itself a fossil nature samples. This paper reports the first-hand information about detection of fossil remains found near the Lunar Crater’s water body on the prima facial basis and to put on record the work carried out to search its source and origin.

Numerical and thermal analysis of ceramic coated M550D x Drive Sedan
The piston is considered to be one of the important parts of the internal combustion engine. It is a part which bears the pressure of the combustion of the gas inside the cylinder. Normally they are made up of cast iron which bears the gas weight. It is used to deliver the power via linking rod to the main shaft of the engine. Nowadays they are made of aluminum alloy to keep it lightweight. As the top surface of the piston has to bear the load, it is prudent to cover it with some coating material so that it could bear the thermal load. Piston made up of gray cast iron coated with ceramic material (MgZrO3) which is bonded by special material (NiCrAl) is intended for M550d x Drive sedan by machine design approach to resolve the dimensions of the piston and then it is modeled in ANSYS Workbench 17.1. The pressure of the 5 N/mm2 is applied on the piston. The equivalent stresses are found to be same for both coated and non-coated piston. Thermal analysis of both coated and the non-coated piston is done. The properties like equivalent stresses, temperature variation and total twist under pressure and thermal load are resolute with the change in the thickness of ceramic coating material. It is completed that ceramic coated piston is able to handle thermal load and is indifferent towards structural load.

Parametric optimization in machining on NIMONIC 75 alloy using Electrical Discharge Machining
The increasing demands of machining of complex shape geometries and their high surface finish and has further strengthened the need for non-traditional machining processes. Among various process, EDM has been explored to a large extent owing to surface finish and MRR are of crucial importance in the field of machining processes. Taguchi’s optimization technique, in order to optimize the cutting parameters in EDM for superalloys. The objective of the effect of EDM parameters on MRR, Surface finish for machining NIMONIC75 alloy. In this present study, superalloy is used as a workpiece, copper or copper Alloy Like Brass used as a tool and distilled water is used as a dielectric fluid For experimentation, Taguchi’s orthogonal array will be followed by ANOVA to identify the most significant factor. This would follow by developing an empirical relation and optimization study. Nimonic75 (Nickel chromium base Alloys) is the most commonly used alloy. His basic chemical composition is Ni,Cr,Ti,C,Si,Cu,Fe,andMn. Nimonic75 is significantly strong than other commercially pure nimonic whilst still retaining the same stiffness and thermal properties. Nimonic75 extensively used in Gas-turbine engines Heat-treating equipment and fixtures Nuclear engineering aerospace,medical,marine and chemical processing.

Numerical simulations of equivalent stress of a motorcycle wheel by using ANSYS
The design of a motorcycle wheel contains several complexes and attempt has been made to meet the requirements of original equipment manufacturers (OEMs). By using UNIGRAPHICS (NX 7.5), it involves the drawing wants and design of a motorcycle wheel. The design in 6 degrees of freedom (DOF) for characteristics and durability has been developed. After designing of wheel, the material should be selected and to go through several analysis tests on ANSYS software. By apply different loads in existing Aluminium alloy wheel and analyze the bending stresses, the material has been changed from Aluminium alloy to Polyether-ether ketone, PEEK150GL30, PEEK90GL30 and PEEK150CA30 for the study. In the same design the materials has been changed one by one and applying unlike loads, and analyze the bending stresses. It is concluded that the existing design is suitable for plastic material. Plastic material will deform at a maximum load of 2452.5N (250Kg). So change the design and the resources and analyze the bending stresses and finally conclude that Aluminium alloy can be replaced by plastic material.

Comparative evaluation of gingival thickness in smokers and non-smokers
Smoking has its effects on the periodontium, which is reflected by morphologic and histologic changes in the gingiva. Gingival thickness is one among the factors, which has become a subject of considerable interest in periodontics both from the epidemiological and therapeutic point of view. By taking gingival thickness into consideration during treatment planning, more appropriate strategies for periodontal management may be developed, resulting in more predictable treatment outcomes. The purpose of the study was to estimate the gingival thickness in different regions of the mouth in smokers and non-smokers. The study group included 40 age-matched smokers and non-smokers with and without periodontitis. Gingival thickness assessment was done on 6 index teeth; 6 sites on each tooth by transgingival probing using 15 sizes endodontic reamer and thickness was measured using vernier caliper. A statistically significant difference in gingival thickness was observed in different sextants of mouth in smokers and non-smokers.
