The influence of boron as well with niobium additions on the phase transformation behaviour, resultant microstructures, and mechanical properties thermomechanically controlled hot-rolled direct-quenched low-carbon bainitic steel plates was investigated. Also, probable factors that could inhibit their specific merits hardenability, behaviour properties, were studied. Continuous cooling diagrams ...

considering the increase in waste production, scarcity of land allocated to landfill in urban areas, concerns about ecological damages caused by hazardous waste and damages done to the environment, municipal waste management has become of tremendous importance. the study investigated the behavioral patterns of households regarding waste separation at source using data collected through intervie...

In the present work, deoxidation and refining of 316LVM steel (Low carbon Vacuum Melted) during the vacuum induction melting process was studied. This grade of stainless steel is one of the most import...

Background: Urban Primary Health Centres (UPHC)are different from conventional rural PHCs in term of size, functions, focus on ambulatory care, limited staff and infrastructure. UPHC is also expected to deliver certain job-functions Subcentre through its outreach services. In view these considerations, it is, therefore, appropriate that a separate list standards developed. Methods: This was cro...

When RTL designers define the hierarchy of a system, they exploit their knowledge about conceptual abstractions devised during design and functional interactions between logical components. This valuable information is often lost physical synthesis. article proposes HiDaP, novel multilevel algorithm that uses analytical methods for macro placement problem modern designs dominated by multicycle ...

The purpose of this study was to carry out a scanning electron microscopic (SEM) analysis of the cleaning qualities and smear layer removal from root canal walls, instrumented and irrigated with 2.5% NaOCl, 2.0% chlorhexidine and saline solutions. Fifty extracted teeth were used in this study. All teeth were radiographed to determine the existence of a single canal. The crowns were cut at the c...

In this study, ultrasonic assisted machining (UAM) technique is applied in side-surface milling experiment for glass-ceramic workpiece material. The tungsten carbide cutting-tool with diamond coating is used in conjunction with two kinds of cooling/lubrication mediums such as water-soluble (WS) cutting fluid and minimum quantity lubricant (MQL). Full factorial process parameter combinations on ...

The activation energy for the surface self-diffusion of epitaxial erbium crystals grown on a tungsten field emitter tip has been examined. It was found to be strongly dependent both on the crystallographic orientation of the tip and the direction of electric field applied. The values of the activation energy, calculated from Arrhenius-type plots, and also field emission patterns of epitaxial Er...

y most recent estimates, about two billion of the world’s population B have no access to modern forms of energy, such as electricity or fossil fuelsl. The majority of these people depend on burning biomass wood, dung or waste from agriculture for cooking, heating and lighting, and on human or animal power for tasks such as grindmg and transport. Biofuels and human power trap people into poverty...
