In the present study, beet-root juice concentrates were prepared at different time/temperature treatments viz 45 °C, 55 °C, and 65 °C for 120, 80 and 45 min. The effect of different time/temperature treatments on physicochemical composition, colour, antioxidant activity (%), bioactive compounds, spectral data and sensory acceptance were evaluated. The physicochemical parameters of popsicles (PTI, PT2, PT3) including protein, total phenols, betalain, radical scavenging activity %, colour and melting values were significantly affected (p ≤ 0.05) by the different time/temperature treatments. The concentration of betalain and protein in all the popsicles ranged from 1134 to 1299 mg/L and 1.92 to 1.54 g/100 g respectively. The reduction of bioactive components viz betacyanins, betaxanthins, betanin, oxalic and syringic acid was also observed in popsicle (PTI) as compared to control. Furthermore, popsicle (PT1) was prepared with beet-root juice concentrated at 45 °C showed maximum sensory acceptance. The physicochemical and organoleptic attributes of processed popsicles encourage the commercial usage of whey powder and concentrated beetroot juice.

The reliability R�(t) of a component is the probability that this component will perform its intended function after a time ‘t’ in a given operating condition. Nowadays component reliability is not very important by considering only the power losses. For predicting reliability of power electronics components temperature and temperature cycle are to be determined.. The goal of this paper was to accurately simulate power loss and thermal behavior of a IGBT based Inverter using vendor data and a validated electrical model of a IGBT based VSI. Successful creation and implementation of these models can reduce the cost of design and production, increase reliability, quantify the accuracy of the estimated thermal impedance of an IGBT based VSI module, predict the maximum switching frequency without violating thermal limits,predict the...

Nowadays, the cities and highways are bursting with traffic, and very often long queues of vehicles can be seen at various toll plazas so that they can pay the toll and then able to use the road or highway. So a system is proposed wherein the toll tax could be paid via cashless transactions and people wouldn’t have to wait for a long time for the cash payment of the toll tax. This would save people’s money and time simultaneously. It would also eliminate errors in cash transactions and further ease the job of the toll plaza companies. It would definitely bring down any of the corruptions occurring at the toll plazas. Finally, it would make the existing toll tax collection more efficient and ease our lives a bit more.

In this paper, we discuss about the problem in online mining of data in large transactional database, here we apply association rule for mining the data which helps to remove the redundant rule and helps in compact representation of rules for user. In this paper, optimized algorithm has been proposed for online rule generation. The advantage of this algorithm is that the graph generated in our algorithm has less edge as compared to the lattice used in the existing algorithm. This algorithm generated all the essential rules and no rule is missing. The use of non redundant association rules help significantly in the reduction of irrelevant noise in the data mining process.

The calculated values of phase transition pressure and the vast volume discontinuity in pressure-volume (PV) phase diagram indicate the structural phase transition from rock salt (B1) to zinc blend (B2) structure of potassium chloride (KCl) and Potassium Bromide (KBr). Fair agreement with lattice theoretical data calculated from an interaction potential model composed of Coulomb force, van der Walls force and first and second nearest neighbor repulsive forces is found. The present calculation have revealed good agreement with the available experimental data on the phase transition pressures (5 and 10 GPa). On the basis of Born's stability criteria the relations between the pressure dependence of the bulk modulus (B T), shear moduli (C 44) and tetragonal moduli (C S) to the B1-B2 transition are also investigated.

Research paper thumbnail of Particle size effect on TL/OSL response of NaMgF3:Tb phosphor

The type of preparation route followed greatly affects the luminescence efficiency of a material. Grinding of NaMgF 3 :Tb phosphor for a long time induces several lattice defects in the phosphor. In this work, effect of particle size on TL/OSL response of NaMgF 3 :Tb irradiated by 60 Co source of gamma radiations with a dose of 15 Gy has been investigated. NaMgF 3 :Tb samples has been synthesized by solid state reaction method using different grinding times i.e. 1 h and 5 h. XRD technique confirms its formation and crystallite size is calculated. TL studies show that sample synthesized by 5 h grinding is almost 2 times more intense than the sample obtained by 1 h grinding. Also, a clear enhancement is seen in the shoulder peak of sample grinded for 5 h. This could be due to increase in occupancy of trapped charge carriers in the trap levels. However, the position of main TL glow peak remains same in both the samples. Associated TL kinetic parameters such as order of kinetics, activation energy, frequency factor and trap density have been calculated by deconvoluting the TL glow peaks to understand the TL phenomenon. Continuous-wave optically stimulated luminescence (CW-OSL) decay curves have been obtained under blue LED stimulation for 40 s. Analyzing the CW-OSL decay curves reveal that grinding time significantly affects the OSL intensity of the phosphor as well. The decay constant and photoionization cross-section is determined for the faster and slower components of the total OSL intensity. It could be concluded that the time of grinding taken during preparation of the material has a major role in affecting the concentration of trap levels formed inside the forbidden gap of the phosphor.

However, incessant increasing dose of cisplatin against many cancers including cervical cancer is known for drug resistance and side effects like nephrotoxicity and ototoxicity. Methods: To address above problems, this paper reports using ATM kinase inhibitor (KU55933) and siRNA DNA ligase III to alter the DNA repair response in vitro low dose cisplatin treated HeLa cells. Here, authors performed cell proliferation, MTT cell cytotoxicity, annexin V/PI staining flow cytometery and PI stained cell cycle assays to substantiate observations. Results: This paper reports that low dose cisplatin (10 µM) can show better effects in vitro growing HeLa cells in combination with KU55933. However, we included siRNA DNA ligase III along with KU55933, but data suggest that the level of DNA ligase III protein are not changed due to treatment with siRNA DNA ligase III as shown by immunocytochemistry assay. Even though, level of DNA ligase III is not altered in the present finding, use of KU55933 as combinatorial option with low dose cisplatin produce significant anti-proliferation effects (up to 35%) and also loss of cell viability including apoptotic cell death (up to 30%) in treated HeLa cells. Conclusion: This study suggests that KU55933 in combination with low dose cisplatin may be a good option to bring anti-proliferation and loss of viability in HeLa cells and may be explored in other cancer cell lines as well.
