HIV is a virus that targets and alters the immune system, increasing the risk and impact of other infections and diseases. It transmits through some body fluids, such as semen, vaginal secretions, and blood. Without treatment, the infection might progress to an advanced stage called AIDS. Due to medical advances, people with HIV and access to quality healthcare very rarely develop AIDS once they have started taking HIV treatment. WHO observe, HIV has become a manageable condition, and many people with HIV have long, healthy lives. The life expectancy of a person with HIV is now approaching that of someone who tests negative for the virus, provided that the person takes medications called antiretroviral therapy on an ongoing basis. As of 2019, around 68% of adults and 53% of children with HIV worldwide were receiving lifelong treatment.

The book discusses the development and characterization of dental hybrid composite material for restorative work. The reinforcement of ceramic alumina particulates in polymer matrix like BIS-GMA will improve its mechanical and tribological properties, which make them prominent candidates for dental application. The thermal and thermo-mechanical characteristics have been improved with alumina particulate reinforcement.

Illness has been mans heritage from the beginning of his existence and the search of remedies to combat it is perhaps equally old. Antibiotics are prescribed in dental practice for prophylactic and therapeutic reasons. Dentist prescribe between 7% and 11% of all common antibiotics. A sound knowledge of appropriate prescribing of antimicrobial among health professionals is thus critical in combating the resistance. This book is an insight onto the judicious use of antibiotics and how effectively we could use antibiotics in various branches of dentistry to tackle the emerging resistance.

Scissor lift operators and site managers at corporations large and small take on jobs that can be handled more efficiently and safely with a mechanical lift that is properly matched to the task at hand. Operators and site managers use them to increase productivity, improve safety and save money, but they will only succeed when they have the right equipment for the right project. Most scissor lifts have a diverse range of uses, but it can be detrimental if the lift does not have the right size, capacity, height or other specifications needed for the job. Some jobs don't come easy without necessary equipment aid like scissor lifts.

Solar energy becomes an essential requirement in present days. It is very important energy resource in the aspect of environment safety, simplicity and availability. Solar energy is widely using this time all over the world and India is a country which is leading in use of this. The solar energy setup has high initial cost, low efficiency (PCE) and lack of disposal methods. These drawbacks are regularly overcome by researches in this field. These drawbacks suggest is to bring the use of such materials which gives a high PCE at low cost. While selecting the suitable material for PC its hazardous effect on environment should also keep in mind.

This book will focus on design and development concepts related to remote operated forklift. The forklift is defined as a tool capable of lifting hundreds of kilograms of weight. It is a vehicle similar to small truck that has two metal forks on the front used to lift cargo. The operator drives the forklift forward the forks are pushed under the cargo, and then weight is lifted several feet in the air by operating the forks. The forks, also known as blades are usually made out of steel and can lift up to a few tons.

Sheet metal forming is a common process to produce various sheet metal based products like cylindrical cups, square cups etc. It has various types of defects which can reduce product quality, but wrinkling is the most critical defect in sheet metal products. Flange wrinkling is very common problem in sheet metal form based products and this is due to undesirable deformation of sheet, thickness and compressive stresses. When drawing process starts and increase draw depth, after certain height the flange region plastically buckles into a number of waves and the process fails down. It was found that small scale industries working in this field have less technical knowledge for forming defects.
