In this research the strength and durability parameters of recycled aggregates are studied to determine the optimum quantity of recycled aggregates that can be used as substitute for natural aggregates without affecting the strength of concrete. Compression test, Water penetration Test and Rapid Chloride penetration test were conducted on specimens of Grade M40, M50 and M60 with 0, 40, 60 and 80 % of replaced aggregates. For compression test the cube was cured for 28, 56 and 90 days, and for durability test (Water penetration Test and Rapid Chloride penetration test) cube was cured for 28 days. The result is obtained and compared with that of natural coarse aggregate. It is found that use of recycled aggregates does not decrease the strength of concrete substantially.

HFC-32 is being considered as one of the replacement option for HCFC-22 in room air conditioners. HFC-32 is non ODS and its GWP is 675. HFC-32 is moderately flammable and is classified under A2L under latest ASHRAE 34 standard. The volumetric capacity of HFC-32 is about 60% higher compared to HCFC-22. This demands smaller size compressor for HFC-32 for equivalent capacity of HCFC-22. HFC-32 operating pressures (condensing and evaporating) are higher in the range of 60% to 80% than HCFC-22. HFC-32 gives lower pressure drop in heat exchangers than both HCFC-22 and R410A. The pressure drop for HFC-32 in evaporator is about 8% lower than R-410A, and 36% lower than HCFC-22. In condenser, pressure drop are much lower than pressure drop in evaporator. The discharge temperature of HFC-32 is higher than HCFC-22. In this paper, the simulated performance of split air conditioners (SAC) using HFC-32 with nominal cooling capacity of 5.2 kW is compared with finned tube condenser (FTC) and parallel flow condenser (PFC). The simulation has been carried out for SAC using test conditions prescribed in Indian Standards IS 1391 (1992) Part I. PFC gives about 4% and 6.3% higher cooling capacity and EER respectively than that of FTC. PFC gave 9 oC lower discharge temperature compared to FTC. HFC-32 charge inside the SAC is about 17.3% lower compared to FTC.

In the present paper, the effect of a centrally placed circular obstruction on sloshing frequency and sloshing mass is studied for annular tanks. Finite element approach (ANSYS software) is used to model the liquid. For circular tanks without obstruction, sloshing frequency and sloshing mass at first three modes are obtained using finite element analysis which compare well with the available analytical results. Next, a rigid circular obstruction at the center of tank is modeled and sloshing frequency and modal mass in the first three modes are obtained. It is observed that with the increase in the diameter of the circular obstruction, the sloshing frequency and the percentage of liquid in sloshing mode decrease in first mode. The behavior of these sloshing parameters in higher modes is also discussed. A detailed study over wide range of circular tank geometries is performed. Charts for obtaining sloshing parameters for various tank geometries are plotted.

Root canal treatment (RCT) is repairing and saving the badly decayed or infected tooth. Endodontic means treating tooth from inside and Obturation is a process of complete filling and sealing of 3D root canal space with gutta percha as biocompatible sealing material against bacterial growth. The main cause of Endodontic treatment failure is the incomplete sealing of the root canal. The degree of endodontic success depends to greater extent on mechanical sealing of root canal cavity with gutta percha. One of the means to quantify measures for evaluating Root canal success is to get compaction loading pattern during Obturation and corresponding Radio-visio-graph. Current paper discusses a brief review and automation used in the Obturation process to extract experimentally the compaction load pattern on C2 curvature tooth.

In multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) systems, multi-user detection (MUD) algorithms play an important role in reducing the effect of multi-access interference (MAI). A combination of the estimation of channel and multi-user detection is proposed for eliminating various interferences and reduce the bit error rate (BER). First, a novel sparse based k-nearest neighbor classifier is proposed to estimate the unknown activity factor at a high data rate. The active users are continuously detected and their data are decoded at the base station (BS) receiver. The activity detection considers both the pilot and data symbols. Second, an optimal pilot allocation method is suggested to select the minimum mutual coherence in the measurement matrix for optimal pilot placement. The suggested algorithm for designing pilot patterns significantly improves the results in terms of mean square error (MSE), symbol error rate (SER) and bit error rate for channel detection. An optimal pilot placement reduces the computational complexity and maximizes the accuracy of the system. The performance of the channel estimation (CE) and MUD for the proposed scheme was good as it provided significant results, which were validated through simulations.

During the impact of seismic waves, we observe greatcollateral damages as ground shakes every structureconnected to ground face the impact. What if we detach thestructure from ground or base? Friction pendulum as a baseisolator works in similar way by decoupling the structure fromits base and hence reducing the responses that damages thestructure.As concept of single friction pendulum was introduceit was observed that it displaces in large space which causeddifficulty in installing multiple bearing at one site. So toovercome this situation new bearing were designed in whichmultiple plates slide over each other. Due to its mechanism ofsliding over multiple plates, their performances were betterthan single friction pendulum, though using less space to slide.Triple friction pendulum was highly preferred when it comesto select for base isolation, because of its adoptive naturetowards all three level of earthquake (SLE, DBE, and MCE).This paper summaries response analysis of optimizedtriple friction pendulum (TFP) at base of 9 storey RCC buildingunder seismic waves. The building is situated in earthquakezone V as per IS1893:2002. As for reference it is comparedwith fixed base structure under same seismic condition. Theresults indicate by addition of triple friction pendulum at baseof structure, significant decrease in responses like storey drift,storey shear, spectral acceleration, input energy was observed.Also, it obviously leads to increase in fundamental time periodof structure. One of major aspect of triple friction pendulumwas taken care of, that is, re-centering capability of plates byplotting the displacement-time graph of each link.

In this study, an attempt was made to establish green energy from agricultural waste (orange peels). Activated carbon (AC) was produced from orange peels with chemical activation agent i.e. phosphoric acid (H3PO4) by the carbonization activation process. The influences of the process, carbonization temperature, and activation temperature (600°C) for time 2 h with H3PO4 of 1:1 ratio on the resulting activated carbon properties were evaluated. The AC is an excellent adsorbent and its applications are widely described in the literature. Prepared ACs are characterized by standard methods like XRD, SEM, FTIR, and XRF. XRD analysis is used to study the presence of a highly organized crystalline structure for AC. The surface chemical characteristics of activated carbons were determined by the FT-IR method. The microstructure of the produced activated carbons was examined by scanning electron microscopy (SEM). XRF is used to study the different concentrations of inorganic elements present in the produced AC. The result also shows the presence of seven elements with their concentration. Thus present study adds one more bio-waste source as useful raw material for the preparation of AC.
