International Research Journal on Advanced Science Hub, 2021, Volume 3, Issue Special Issue 7S, Pages 1-6

Crack formation is a very common phenomenon in concrete structures which allows the water and chemicals through the cracks and decreases the durability and strength. For repairing the cracks developed in the concrete, it requires maintenance and special type of treatment. So, to overcome this problem an autonomous self healing mechanism is introduced into the concrete which helps to repair the cracks with the help of Bacillus bacteria by producing calcium carbonate crystals which seals the micro cracks and pores in the concrete. For the isolation of bacteria nearly eighty soil samples were collected from soils of extreme environments and cultured in three different media. A total of two thousand seventy colonies were observed and fifty five Bacillus colonies were isolated and identified by Gram staining and different biochemical tests.

International Research Journal on Advanced Science Hub, 2021, Volume 3, Issue Special Issue 7S, Pages 20-24

Fiber metal laminate (FML) belongs to metallic materials class consisting of layers of metal and fiber composite laminates which bonded together. This permits the structure to behave as very simple metal structure with affordable properties such as good resistance to corrosion, high strength to weight ratio, good resistance to fire, better fatigue properties. For the last few decades, the Fiber Metal laminates (FML) which yields high performance as a light weight material and accordingly its increasing demand in aircraft industry have a strong basement towards the development of refined fiber laminated structures. As a hybrid composites these FML’s is a composition of fibers reinforced material bonded with thin metal layers. The most common types of FMLs are CARALL (carbon reinforced aluminum laminate), GLARE (glass reinforced aluminum laminate), ARALL (aramid reinforced aluminum laminate), CentrAl, that bounded by a GLARE core and layers of aluminum. These hybrid composites which have two key constituents namely aluminum metals and fiber-reinforced laminate, offer numerous advantages such as resist fatigue failure and overcome the crack growth mostly in aircraft applications.Glare composed of thin aluminium sheets that are bonded together using an epoxy adhesive film in which glass fibers are embedded. The presence of the epoxy layers causes the attention has to be given to moisture ingress, which can occur during the aircraft service life.An important parameter that might influence the material properties is the service temperature. During the day time the ambient temperature changes from - 40o to 55o C. The in-service temperature of the airplane changes from -55o C to 70oC. Especially the increased or elevated temperatures could affect the material properties of the epoxy and thus the glare properties. Hence this study mainly focused on temperature influences on glare material when the laminate thickness is considered as variable and total heat flux is calculated for the temperature differences.

International Research Journal on Advanced Science Hub, 2021, Volume 3, Issue Special Issue 7S, Pages 25-29

In this paper the effect of arc oscillation and pulsed current of gas tungsten arc welding (GTAW)on the microstructure and mechanical properties of aluminium alloy 2219 was studied. Microstructural characterisation of the weld region was carried out using optical micros copy and Electron probe micro analysis (EPMA). Hardness measurements were carried out using Vickers hardness tester to evaluate the hardness in the base metal and weld zone. The microstructures of Arc oscillation and pulsed current (AOPC) welds and continuous current (CC) welds were compared and their hardness were correlated. It was observed that arc oscillation and pulsed current weld resulted in fine equiaxed grain structure whereas continuous current welds resulted in columnar structure. The significant improvement in mechanical properties of arc oscillation and pulsed current welds may be attributed to the discrete copper segregation. Post weld deformation has improved the mechanical properties of arc oscillation and pulsed current welds significantly. Aging can be carried out at lower temperature with prior deformation to improve the mechanical properties of the weld

Brinjal or eggplant is a very important crop (vegetable) of sub-tropics and tropics of India. This plant is highly infested by, Henosepilachna vigintioctopunctata (Coleoptera: Coccinellidae). It is a polyphagous pest in nature, the adult and grub stages cause severe damage to the plants by feeding on its leaves, flowers and vegetables and create a heavy economic loss. Though the beetles could be controlled using synthetic pesticides, indiscriminate use of pesticide in the field causes problems such as pest resistance, environmental and health hazards etc. These pave way for the development of effective ecofriendly pest control measures. Plant based essential oils are used against these insect pests, as they constitute a rich source of bioactive components and reported to have many biological properties. Recently, essential oils were formulated as nanoemulsion and was developed for their effectiveness and eco-friendly nature. In this study, the oil in water (O/W) nanoemulsion of Mentha piperita were prepared by ultrasonication method at different concentrations and examined for the stability study. The stable nanoemulsion was characterized by DLS and was reported to consist with a mean droplet size of 10.84 nm, PDI was 0.1 and zeta potential was -45 mv which proved the good stability of the nanoemulsion. To assess the efficacy of the formulated nanoemulsion, and bulkemulsion, it was screened against the adult beetles, Henosepilachna vigintioctopunctata at different concentrations for 96 hours and the resulted LC50 value of nanoemulsion was 15.84 % which was found to be very effective than the LC50 value of bulkemulsion, which was 60.25 %. Hence from the results obtained, Mentha piperita nanoemulsion may be used as an organic pesticide because of its higher efficacy against the adult beetles, Henosepilachna vigintioctopunctata.
