Abstract: Providing drinking water to a large rural population is an enormous challenge. 1.95 lakh habitations in the country are affected by poor water quality. The government has undertaken various programmes since independence to provide safe drinking water to the rural masses. In India, investments in community water supply and sanitation projects have increased steadily from the 1st plan to the 10th plan. Till the 10th plan, an estimated total of Rs.1,105 billion spent on providing safe drinking water. However, despite such expenditure lack of safe and secure drinking water continues to be a major hurdle and a national economic burden. It is essential that communities and panchayats are actively involved in the planning, implementation and execution of programmes for water supply. Government should made significant interventions to improve the quality of drinking water in rural areas.

Shot peening is one of the most popular surface enhancement technique used to improve fatigue performance of different materials. This paper focuses on to study the effect of different shot peening parameters on micro-structural and mechanical properties of DIN 1.2714 tool steel specimens. Shot peening treatments were carried out by varying shot size and peening intensity. X-ray stress analysis, micro-hardness testing and micro-structural analysis were performed to characterize these specimens. In addition, pin on disk wear testing was executed to recognize wear behavior of this shot peened tool steels. It was observed that along with compressive residual stress generation, shot peening also induces work hardening effect and modifies surface structure which are responsible for significant improvement in this tool steel.

International Journal of Electrochemical Science , 2008,
Abstract: Structure tailoring of electrodeposited Mo (IV)-oxide thin films by thermal oxidation in ambient air to obtain electrochromic Mo (VI)-oxide thin films was exploited for the first time by novel route. Electrosynthesis of Mo (IV)-oxide thin films on Fluorine-doped SnO2 conducting glass (10-20 W/) substrates were carried from aqueous alkaline solution of ammonium molybdate at room temperature. The physical characterization of as-deposited films showed the formation of hydrous and amorphous MoO2. Scanning electron microscopy pictures and x-ray diffraction of air-annealed films clearly revealed a rod-like morphology and orthorhombic a-MoO3 phase. Samples exhibited pronounced cathodic electrochromism.

International Journal of Pharmacology , 2011,
Abstract: Pet ether, chloroform and methanol extracts of roots of blue and white flowered varieties of Clitoria ternatea were studied for their antioxidant potential. DPPH free radical scavenging assay, reducing power assay, hydroxyl radical scavenging assay were studied for evaluation of antioxidant potential. Pet ether, chloroform and methanol extracts roots of blue and white flowered varieties of Clitoria ternatea (CT) significantly inhibited the DPPH free radical at the concentrations ranging from 50-600 g mL-1. Pet ether, chloroform and methanol extracts roots of blue flowered variety of CT showed highest inhibition i.e., 49.11, 35.42 and 70.67% at 600 g mL-1, respectively. Pet ether, chloroform and methanol extracts roots of white flowered variety of (CT) showed highest inhibition i.e., 54.48, 39.21 and 78.13% at 600 g mL-1, respectively. Methanol extracts of blue and white flowered varieties of CT showed a very powerful antioxidant activity in DPPH radical-scavenging assay. Methanol extracts of CT also showed significant reductive ability as well as hydroxyl radical scavenging activity. Methanol extract of white flowered variety of CT showed more significant antioxidant activity as compared to blue flowered variety of CT. All the concentrations of methanol extract of CT (MECT) antioxidant activity when compared to control and these differences were statistically significant (p<0.001). Clitoria ternatea Linn. could be considered as a potential source of natural antioxidants.

New Zealand (NZ) young rabbits with the administration of insulin-like growth factor (IGF-1) and transforming growth factor-β (TGF-β) with and without mandibular anterior repositioning appliances are explored for the growth of the mandibular condylar cartilage (MCC). 32 growing NZ and rabbits were divided into 4 groups: the group with saline injection in TMJ, the group which received growth factor injection in TMJ, the group which received anterior positioning appliance and the group which received growth factors injection as well as mandibular repositioning appliance. Gene expression was studied by real-time RT-PCR and cartilage growth by histomorphometry. Administration of growth factors along with mandibular repositioning appliances has induced 1) 1.70-fold expression of Col-2Agene (p value < 0.0005) and 2) 1.47-fold expression of Col-10Agene (p value < 0.0005). In contrast, administration of only mandibular repositioning appliances induced 1) 1.28-fold expression of Col-2Agene (p value < 0.0005) and 2) merely 0.62-fold expression of Col-10Agene (p value < 0.0005), while administration of growth factors only induced 1) mere 0.56-fold expression of Col-2Agene (p value <0.0005) and 2) 0.86-fold expression of Col-10A gene (p value < 0.0005). Administration of growth factors along with mandibular repositioning appliances causes an increase in genetic expressions which have been corroborated by histomorphometry and validated by statistical analysis, during an accelerated growth of mandibular condylar cartilage. Administration of growth factors in the TMJ could provide a synergistic role along with mandibular repositioning appliances for treatment of mandibular retrognathism as well as disorders on the MCC.

Abstract: As per WHO, only few drugs are frequently used in the treatment of helminthes in human beings. Anthelmintics from the natural sources may play a key role in the treatment of these parasite infections. Other species of Ficus viz., Ficus benghalensis, Ficus racemosa, Ficus inspida were found to be reported to have anthelmintic activity. In view of this an attempt has been made to study the, in vitro anthelmintic activity of different extracts of leaves of Ficus carica Linn. against Pheritima posthuma.Each extract was studied at 20 mg/ml in the bioassay, which involved determination of time of paralysis and time of death of the worms. Mebendazole (20 mg/ml) included in the assay as standard reference drug. The result shows that methanol and aqueous extracts of Ficus carica were showed significant anthelmintic activity and thus Ficus carica Linn. would be useful as an anthelmintic.

Abstract: Metal ceramic restorations have been implicated for the discoloration in area of labiogingivalmargin. Attempts to rectify this, by altering the design of metal frameworkswill lead to decrease in fracture strength atmargin. This in vitro study compared the fracture strength at margins of metal ceramic crowns cemented to metal tooth analogs. Crowns evaluated with different marginal configurations, shoulder and shoulder bevel with 0?mm, 0.5?mm, 1?mm, and 1.5?mm, were selected. Methods. Maxillary right canine typhodont tooth was prepared to receive a metal ceramic crown with shoulder margin. This was duplicated to get 20 metal teeth analogs. Then the same tooth was reprepared to get shoulder bevel configuration. These crowns were then cemented onmetal teeth analogs and tested for fracture strength atmargin on an Instron testing machine. A progressive compressive load was applied using 6.3?mm diameter rod with crosshead speed of 2.5?mm per minute. Statisticaly analysis was performed with ANOVA, Student's “ ” test and “ ” test. Results. The fracture strength of collarless metal ceramic crowns under study exceeded the normal biting force. Therefore it can be suggested that collarless metal ceramic crowns with shoulder or shoulder bevel margins up to 1.5?mm framework reduction may be indicated for anteriormetal ceramic restorations. Significance. k Collarless metal ceramic crowns have proved to be successful for anterior fixed restorations. Hence, it may be subjected to more clinical trials. 1. Introduction Metal ceramic crown has always been the most popular complete veneer restoration in dentistry, because it derives its aesthetics from the highly translucent natural appearance of porcelain and the strength from the metal substructure [1, 2]. But optimum aesthetics is not achieved consistently with conventional ceramometal restorations, particularly in area of labiogingival margin [3]. Research has shown that metal collars diminish light transmission into the adjacent tooth tissue, causing darkened appearance of both root surfaces and gingival [4]. Hence, the choice of restoration would be, that has the structural advantages of the metal ceramic restoration and the aesthetic qualities of the all ceramic crown, especially on the cervical third [5]. These requirements have led to the development of facial porcelain margin in metal ceramic crowns, also known as collarless metal ceramic crown. In collarless metal ceramic crowns, the facial porcelain margin eliminates the unpleasing metal collar, due to increased thickness of porcelain at the gingival margin.
