Mass spectrometry is a technique which is used in the identification of various types of chemical present in the sample. It is also used in the quantification of amount of specific chemical in the sample. Mass spectrometry is very common technique in analytical laboratories which helps in the study of biological and chemical properties of compounds. In life science area, mass spectrometry is primarily involved in the characterization and sequencing of proteins. It identifies and quantities crucial proteins involved in disease and altered phenotypes and recognized diagnostic biomarkers for treatment.

Uveitis is the inflammation of middle layer of eye commonly known as uvea. Uvea consists of pigmented and non pigmented tissues which are present in the middle layer of the eye. The uvea is also known as uveal tract. The uveal tract is important for eye nutrition and for reduction of glare of light which enters into the eye through absorption of the light. In addition, uvea also helps in aqueous humour generation and eye lens protection. The uvea consists of choroid, iris and ciliary bodies. Choroids exist between the retina and the white part of the eye. Choroid helps in blood flow to the deep layer of the retina. Iritis, an inflammation of iris, is the most common form of uveitis. Anterior uveitis, posterior uveitis, intermediate uveitis and pan uveitis are some of the types of uveitis. Anterior uveitis involves inflammation of front part of eye. It is the most common type of uveitis and affects young and middle age people. Posterior uveitis includes the choroid, a layer of connective tissues and blood vessel in the middle part of the eye. Posterior uveitis results into inflammation of back part of uvea. Blurred vision, eye pain, redness of eye, dark floating spot in vision and sensitivity to light are some of the symptoms for the uveitis.

Hepatitis B refers to an infectious disease that is caused by hepatitis B virus. Symptoms of this disease are not visible in initial stages and develop after few weeks only. Hepatitis B virus is transmitted by exposure to infectious blood or body fluids of an infected person. This disease may even occur from the birth. Hepatitis B may be caused by blood transfusions, healthcare setting, sharing razors and dialysis. Hepatitis B vaccine refers to a vaccine that is developed for prevention of hepatitis B virus infection. Hepatitis B vaccine consists of viral envelope proteins and hepatitis B surface antigens (HBsAg). Hepatitis B vaccine is produced by using yeast cells. Medication course for hepatitis B vaccine consists of two or three injections. These injections are given at a time interval of about one month. The first and second doses provide full protection against infection. Final or third injection is given to prolong the effect of hepatitis B vaccine. As a result of this medication, an immune system is developed in the patient’s body which produces an antibody to HBsAg. This antibody is called as anti-HBs. This antibody provides protection against hepatitis B infection. In addition, immune system memory helps to provide resistance against hepatitis B virus. The global market for hepatitis B vaccine is growing at a significant rate due to increasing number of cases with hepatitis B infection. In addition, growing population and growing awareness for improved healthcare facilities is increasing the global market for hepatitis B vaccine. Various types of hepatitis B vaccines are available in the market, such as recombinant DNA vaccines that is produced by insertion of hepatitis B virus.

Road maintenance is very important in order to keep the road in its originally constructed condition, protect its close resources and user safety and provide smooth and convenient travel along the route. A proper maintenance of the road is required as it is impossible to build maintenance free roads. With the help of road maintenance machinery, roads can be maintained for a longer period of time. Additionally, drainage system should be maintained so that drainage should be free of trash and obstruction. On newly constructed roads cleaning may have to be more frequent. Proper road maintenance could result in reliable transport at reduced cost, as there is a direct connection between road condition and vehicle operating cost. An improperly maintained road can results in more accidents. So it is very important to maintain road from safety point of view. Different activities were carried out to maintain road. Activities such as periodic works, special works, development and periodic works were carried out. Routine works are undertaken each year and it can be grouped into reactive and cyclic work types. Cyclic works are undertaken on environmental effects rather than on traffic levels. Reactive works are undertaken when the maintenance is required. For instance patching, this is carried out in result of appearance of cracks. Periodic works are undertaken at intervals of several years to maintain the structural integrity of the road. Special works are undertaken during emergencies such as landslides and washouts, roads are cut or impassable. Development works are undertaken at the event of construction of highways and paving of unpaved roads in villages. In order to carry out these activities, different road maintenance machinery include paver, grader, road roller, asphalt mixing plants and asphalt pavement are required.
