Abstract- Reactive Powder Concrete (RPC) is a high strength, new era concrete, framed from a unique mix of constituent materials. The basic composition of making reactive powder concrete includes cement (ordinary Portland cement), fine sand, silica fume, quartz powder, and high ductile steel filaments. Reactive powder concrete is grouped under ultra-high performance concrete. This concrete has a very high compressive strength of 200 MPa which can be enhanced further by introducing steel fibres, up to 800MPa. This new group of concrete has enhanced ductile behaviour with a flexural strength of 25MPa to 40MPa. Kaolin does not have numerous cementations properties by itself, but rather in the presence of water, it reacts with lime creating highly hydrated products, which not only improves the strength but also improves the durability. In this research paper, investigation on concrete properties has been studied out by making RPC through different mix design.

Keywords: Ultra-High Performance Concrete, High Strength concrete, Reactive powder concrete, Kaoline, Silica Fume.

Abstract- Dengue viruses (DV) belong to family Flaviviridae and there are four serotypes of the virus referred to as DV-1, DV-2, DV-3 and DV-4. DV is a positive-stranded encapsulated RNA virus and is composed of three structural protein genes, which encode the nucleocapsid or core (C) protein, a membrane-associated (M) protein, an enveloped (E) glycoprotein and seven non-structural (NS) proteins. It is transmitted mainly by Aedes aegypti mosquito and also by Aedes albopictus. Dengue viruses (DENVs) can cause about 50-100 million infections to humans and up to 50,000 deaths per annum. The viral Structural envelope protein of dengue virus 4 is involved during the infection of dengue fever disease, which made them effective drug targets for treating this disease. The Structural envelope protein is a lipid bilayer containing two envelope-associated proteins: the Envelope and Membrane proteins. The nucleocapsid is about 30nm in diameter and covered by envelope. The Envelope protein is glycosilated and responsible for attachment to the cellular receptors and fusion with cell membrane. The Envelope protein contains the main epitopes recognized by neutralizing antibodies. Hence an Insilico attempt was made to characterize a viral envelope protein of dengue virus -4 to identify the potential drug to inhibit the protein. The plant based natural compounds which were used as Ayurvedic medicines in various diseases and Marine Animal Sources are used as natural ligands for molecular docking process with protein drug targets using glide (version 5.6) of Maestro (10.2) (Schrodinger suite). The natural anti-viral drugs namely Rutin which was isolated from ginger (Boesenberdia rotunda) an herb plant was found to have a good inhibitory effect on viral envelope protein. Here by it is concluded that these natural compounds were found to have good binding affinity with these target protein and considered to be effective drug targets for treatment of dengue fever.

Abstract- This paper presents an investigation which dealt with the performance of control cement mortar and metakaolin modified mortar along with addition of cerafiber-mix. Metakaolin was replaced by 0 to 30% by weight of cement with same water binder ratio of 0.46. Cerafiber-mix was also added to the MK modified mixes. The flow of different mixes was tabulated. The flexural strength, compressive strength and split tensile strength were found for the specimens. The flow of different fresh mortar mixes was determined using flow table instantaneously. Water absorption for every specimen after 28 days was also recorded. The resistance against acid (H2SO4) was also investigated.

The results indicate that the mortar with 25% replacement shows higher performance when compared to other samples. The flexural strength, compressive strength and split tensile strength is maximum at 25% metakaolin replacement and beyond 25% strength start reducing. Sulfate attack was observed with 0.2%, 0.5%, 1.0% of sulfuric acid at different ages, weight loss was observed and it results that strength decreases beyond 20% of metakaolin replacement.

Abstract- Concrete occupies unique position among the modern construction materials. Concrete is a material used in building construction, consisting of a hard, chemically inert particulate substance, known as a aggregate, that is bonded by cement and water. Geo-polymer is an inorganic alumina-silicate compound, synthesized from materials of geological origin or from by-product materials such as fly ash, rice husk ash, etc., that are rich in silicon and Aluminum (Pozzolan) combined with alkaline activator. The geo-polymer technology could reduce the CO2 emission to the atmosphere caused by cement and aggregates by about 80%.Direct alkaline activation of industrial wastes, such as fly ash can be employed to produce Geo-polymer which can be gainfully utilized to manufacture novel concretes for constructions. It is essentially cement free concrete. This material is being studied extensively and shows promise as a greener substitute for ordinary Portland cement concrete in some applications. Research is shifting from the chemistry domain to engineering applications in commercial production of geo-polymer concrete. It has been found that geo-polymer concrete has good engineering properties with a reduced global warming potential resulting from the total replacement of ordinary Portland cement. The research undertaken at various universities has included studies on geo-polymer concrete mix design, structural behavior and durability. This project presents the results from studies on M20 concrete and compares the strength of geo-polymer concrete with ordinary concrete under same conditions. The compressive strength for the casted cubes is tested after 7 days and 28 days for different curing techniques (ambient, water and oven cured).

Abstract- The open ground storey is an unavoidable functional requirement of all the urban multistorey RC buildings and hence it cannot be eliminated. Studies from past earthquakes shows that RC frame buildings with open ground storeys are recognized to perform poorly during in strong earthquake shaking. In this study, ten Models of G+6 RC frame buildings were modelled and analaysed by linear time history method in ETABS 2015 software. And Model-I (ground open RC building) was compared with other nine Models comprising of open ground storey stiffened with masonry infill walls, RC shear walls and steel bracings with different patterns. The results obtained from the analysis depicts that by increasing stiffness of the open ground storey in RC building, the storey displacements, storey drifts, maximum bending moments and maximum shear force in columns will be reduced considerably. It can be also concluded that if at least periphery RC shear wall or steel braces are provided, then soft storey effect can be minimized. It is better to provide masonry infill walls, shear walls or steel bracings in ring pattern, as it will not affect the parking of vehicle and it reduces the maximum soft storey effect.

Abstract- MIMO –OFDM (Multiple –Input Multiple Output-Orthogonal Frequency Division Multiplexing) system has been currently recognized as one of the most competitive technology for 4G mobile Communication system. The signal detection technology has proposed in this paper for MIMO-OFDM system is MMSE Equalization. The performance is calculated in terms of Bit Error Rate (BER) versus the Signal to Noise Ratio (SNR). In this paper I have been proposed the BER performance of the MIMO-OFDM system with MMSE equalizer for various modulation techniques i.e. BPSK, QPSK, 16-QAM and 64-QAM using multipath fading channels i.e. AWGN (Additive White Gaussian Noise), Rayleigh and Rician channel. Multiple-Input Multiple-Output (MIMO) systems have been emerged as a technical breakthrough for high-data-rate wireless transmission. The performance of MIMO-OFDM system can be improved by using different antenna selection so as to provide spatial diversity. In this paper, the performance of MIMO system over AWGN (Additive White Gaussian Noise) and Rician fading channels with MMSE receiver is analyzed using different antenna configurations.

Abstract- In this dissertation, the MHD boundary layer flow with heat and mass transfer on a porous medium over a stretching sheet with chemical reaction, Soret and Dufour effect is considered. The governing equation under the boundary layer condition is considered in the form of coupled and nonlinear. These equations are then solved by using fourth order Runge Kutta method with shooting technique. In order to get physical insight of the problem we have studied the main flow, skin friction, heat and mass flux as functions of various parameters Reynolds number, Prandtl number, Suction parameter, Frequency parameter, Schmidt number, thermal Grashof number and mass Grashof number. The effect of flow parameters on velocity filed, temperature field, concentration field, skin friction, Nusselt number and Sherwood number have been analyzed numerically and discussed with the help of numerical values.

Keywords: MHD, Porous medium, heat generation, Soret effect, Dufour effect.
