Design and implementation of Automatic Aquarium System using IOT

In modern days many people have fish as their pets in home. Everyone loves fishes and required aquarium for their home. But maintaining aquarium is difficult task. We need to change water time by time, feed fishes time to time. Again it is difficult to check the conditions of an aquarium manually. Therefore it important to automate aquariums. Here we have implement an IOT based system which monitor and control the whole aquarium automatically and provide real time status on user�s Smartphone application. It contains water quality management in which It will monitor the physical changes in the water and will maintain it to the ideal conditions, with required changes. The aquarium will perform all the steps automatically like temperature control, turbidity level control, light monitor, feeding, water renewal etc. It will reduce the manual effort required in maintenance of aquariums by automating the aquarium management process. also automatic food feeding system operated by servo motor mechanism which used to feed fishes on regular time intervals. Dead fish mechanism is there which will detect the dead fish. In addition camera is connected to aquarium system using which user can see live operation occurring in system with the help of smart phone. The aim of our project is to replace manual maintenance of fish aquarium with an Automated system by using IOT

Hypercholesterolaemia - practical information for non-specialists

Hypercholesterolaemia is amongst the most common conditions encountered in the medical profession. It remains one of the key modifiable cardiovascular risk factors and there have been recent advances in the risk stratification methods and treatment options available. In this review, we provide a background into hypercholesterolaemia for non-specialists and consider the merits of the different risk assessment tools available. We also provide detailed considerations as to: i) when to start treatment, ii) what targets to aim for and iii) the role of low density lipoprotein cholesterol

INVESTIGATION OF SURFACE TEXTURED CUTTING TOOLS FOR SUSTAINABLE MACHINING

Abstract The profligate use of cutting fluids in machining causes serious health issues for operators; additionally, there are increasing economic and environmental costs associated with managing cutting fluid systems. To improve the sustainability of machining processes researchers are making efforts to eliminate or reduce the use of cutting fluids during machining through several means: development of improved tool coatings, materials and cutting fluids, hybrid machining processes, process optimization, etc. More recently, some researchers have studied the application of controlled surface micro textures on cutting tool surfaces to improve machining performance through alteration of tribological conditions at the tool-chip and tool-workpiece interfaces. This paper presents the results of an experimental investigation involving dry and near-dry intermittent orthogonal cutting of AISI 1045 steel using uncoated P30 grade cemented tungsten carbide cutting tools with various surface textures applied on the cutting tools' rake surfaces via grinding. The results show the significant effects of the cutting tool's rake surface roughness on machining forces and surface roughness of workpieces. Based on the observed trends some areas for further research in cutting tool development are identified
