Cr

The effects of Cr and Fe, singly and incombination were investigated on nutrients uptake (Cu, Zn and Mn), lipid peroxidation, antioxidant enzymes, chlorophyll content and growth parametersi n Zea mays L. var. Ruchi (SRHM445). Roots of the Cr treated plants were stunted and root hair formation was
greatly impaired. The leaves were bearing wilted appearance. Cr was primarily accumulated in the roots with alow translocation rate to the leaves. Cu absorption decreased with increase in Cr concentrations only in roots. In leaves there is no correlation. Iron induced lipid peroxidation was higher in the leaves
at both the concentrations (3 and 9 mg ml1) after 7d, and decreased significantly by the addition of Cr.
Concentrations of most leaves antioxidants were lower in mixed metal treatment compared to single treatments, indicating an interaction between metals leading to reduced cellular effects as indicated by lower lipid peroxidation levels. Changes in APX and GPX activities observed in the leaves of contaminated-plants suggest their involvement in heavy-metal stress tolerance.The plant seems to be tolerant as the translocation of Cr was recorded less, which decreased in the presence of Fe.

The use of Crumb rubber (CR) and High Volume Fly Ash (HVFA) has been shown to enhance the ductility behavior of Engineered cementitious composite (ECC). However, the strength of the composite is known to be negatively affected by CR inclusion as well as the HVFA. Most research on these materials usually focus on the 28 days compressive strength development with very few that considered up to 90 days. No research has so far investigated the combined effect of HVFA and CR on the compressive strength development and shrinkage behavior of ECC beyond 90 days of curing. This paper is aimed at filling this gap by investigating this at 180 days (6 months) curing duration while adopting the RSM design and analysis approach. Result showed that HVFA affects the early strength development of RECC but proves beneficial at later days due to secondary hydration. The highest rate of development in compressive strength of 172% was recorded for a sample with 70% FA. Although the amount of CR negatively affects the strength and drying shrinkage of the composite, it plays no role in the rate of strength development. Response surface models were successfully developed and validated using the analysis of variance (ANOVA)

Image Compression is a wide area. Compression of Images increasing because the raw images need large amounts of disk space seems to be a big disadvantage during transmission & storage. Even though there are so many compression technique already present a better technique which is faster, memory efficient and simple surely suit the requirements of the user. The work is to explain use of different compression techniques more suitable for particular data compression algorithm based on compression ratio, Bit per Pixel, Mean Square Error and Peak Signal to Noise Ratio. Using all four parameters image compression works and gives compressed image as an output.

The luminescence of Cr3+ in natural and calcined diaspore is applied to probe structural properties of the phases. Steady-state luminescence spectra of the natural diaspore [a-AlO(OH)] are typical of 2E→4A2 transitions of Cr3+ luminescence centers (R-lines) substituting for Al3+ in six-fold coordination. The dehydroxylated phase of the diaspore is characterized by a low degree of crystallinity. This phase is not

The high PAPR is an OFDM system is arises because of IFFT operation, where data symbol across subcarrier can add up to produce a high peak value signal. In OFDM system, the peak deviation about average is significantly high, hence the signal level moves outside the dynamic range. Because in OFDM system we are loading the symbol in subcarrier and then take IFFT of this signal. This arises high PAPR, which limits use of OFDM in latest technological advancement such as 4G and 5G.This paper presents an idea to reduce PAPR in OFDM system using selected mapping (SLM) technique. When we want to convert a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies we need to apply Discrete Cosine Transform(DCT), and it is easiest way to do so.

The banking sector is the most dominant sector of the financial system in India, and with
good valuations and increasing profits, the sector has been among the top performers in
the markets. Undoubtedly, being tech-savvy and full of expertise, private banks have
played a major role in the development of Indian banking industry. In the process they
have jolted public sector banks out of complacency and forced them to become more
competitive. At present, Private Banks in India includes leading banks like ICICI Banks,
ING Vysya Bank, Kotak Mahindra Bank, SBI Commercial and International Bank, etc.
Private Banks such as HDFC Bank and ICICI Bank are posting a rapid increase in their
asset base every year as compared to public sector banks. The objective of present paper
is to analyze the financial position of the private sector banks. The analysis reveals that
HDFC is the most efficient bank in terms of generating earning per share. KM B has
higher P/B Ratio it shows that, the higher the premium the market is willing to pay for the
company above its hard assets.

Photoluminescence, absorption and excitation spectra of K2LiAlF6 single crystals doped with 1% of Cr3+ are presented. The near-infrared photoluminescence observed at room temperature, 77 and 4 K are attributed to the zero-phonon spin-allowed 4T2(4F)→4A2(4F) transition of Cr3+ octahedrally coordinated by F- ions. Lifetimes are obtained. The 4 K emission broad band was described in terms of normal modes of the octahedral complex [CrF6]3-. The Racah, crystal-field and Huang Rhys parameters are calculated and the quantum efficiency and thermal quenching estimated and compared with Cr3+ properties in different environments.

Since the announcement by Fleischmann and Pons that the excess enthalpy generated in the negatively polarized Pd-D-D2O system was attributable to nuclear reactions occurring inside the Pd lattice, there have been reports of other manifestations of nuclear activities in this system. In particular, there have been reports of tritium and helium-4 production; emission of energetic particles, gamma or X-rays, and neutrons; as well as the transmutation of elements. In this communication, the results of Pd-D co-deposition experiments conducted with the cathode in close contact with CR-39, a solid-state nuclear etch detector, are reported. Among the solitary tracks due to individual energetic particles, triple tracks are observed. Microscopic examination of the bottom of the triple track pit shows that the three lobes of the track are splitting apart from a center point. The presence of three α-particle tracks outgoing from a single point is diagnostic of the 12C(n,n')3α carbon breakup reaction and suggests that DT reactions that produce ≥9.6 MeV neutrons are occurring inside the Pd lattice. To our knowledge, this is the first report of the production of energetic (≥9.6 MeV) neutrons in the Pd-D system.

Bi2FexCryO6 epitaxial films have been grown on (100)-and (111)-oriented SrTiO3 substrates using dual crossed beam pulsed laser deposition (DCB-PLD). The films crystal structure, chemical composition ferroelectric and magnetic properties were investigated and are reported.

Two types of SBN crystals were grown and analyzed for their spectroscopic and dielec- tric properties: Sr0.33Ba0.67Nb2O6: Cr and Sr0.58Ba0.42Nb2O6: Cr, Yb. The absorption and EPR spectra show the presence of Cr 3+ at interstitial ions beside the ions substituted for Nb 5+ . Unexpectedly, Yb 3+ has not entered to the Sr0.58Ba0.42Nb2O6: Cr crystal at Nb 5+ octahedral sites.

Abstract  In the early twentieth century, a wave of immigration from Eastern and Southern Europe to the United States caused natives' anxiety and debates over the racial purity of “the nation.” By mid-century, these new-comers would be accepted in the ethnic wing of the white race. Across academic disciplines, this immigrant history has become emblematic of how “white people” in the United States are not born but made. Focusing on narratives on “the Balkans” in the popular at the time scientific magazine the National Geographic, this study examines American racial ideas of immigrants from the region from a comparative and cross-national perspective.

Hexavalent chromium, Cr(6+), is a common and toxic pollutant in soils and waters. Reduction of the mobile Cr(6+) to the less mobile and less toxic trivalent chromium, Cr(3+), can be achieved with conventional chemical reduction technologies. Alternatively, Cr(6+) can be biochemically reduced to Cr(3+) by anaerobic microbial consortia which appear to use Cr(6+) as a terminal electron acceptor. A bioprocess for Cr(6+) reduction has been demonstrated using a packed-bed bioreactor containing ceramic packing, and then compared to a similar bioreactor containing DuPont Bio-Sep beads. An increase in volumetric productivity (from 4 mg Cr(6+)/L/h to 260 mg Cr(6+)/L/h, probably due to an increase in biomass density, was obtained using Bio-Sep beads. The beads contain internal macropores which were shown by scanning electron microscopy to house dense concentrations of bacteria. Comparisons to conventional Cr(6+) treatment technologies indicate that a bioprocess has several economic and operational advantages.
