6-Bromo-2-(4-nitro­phen­oxy)-3-(1-phenyl­ethyl)-3,4-dihydro-1,3,2-benzoxaza­phosphinine 2-oxide

In the title compound, C21H18BrN2O5P, the six-membered oxaza­phosphinine ring is in a twist-boat conformation. One of the phosphoryl O atoms is in an equatorial configuation while the other is axial with respect to the oxaza­phosphinine ring. The mean planes of the benzene ring to which the nitro group is attached and the phenyl ring form a dihedral angle of 83.5 (1)°. In the crystal structure, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into chains along [100]

A Robust Data Hiding Scheme In Audio Signal Based On Double Density Dual Tree Discrete Wavelet Transform

ABSTRACT: The outline of this paper is that, we plot a twofold tree twofold thickness discrete wavelet transform (dwt), given the first channel bank.. The procured channels are then refined by nonlinear streamlining, such that they satisfy flawless changing commitments and the following sets of wavelets have the analyticity property. We show two instances of arrange that are through and through preferable over those got with a past method. We demonstrate the power of the shrouded watermark for added substance clamor, Mp3 squeezing, re-quantization, sifting, editing and testing. The correlation examination demonstrates that our system has preferred execution over watermarking plans reported as of late

Not AvailableIncreased protein ingredient (soybean meal) cost made the poultry farmers to seek for an alternative protein source. Hence to test the viability of decorticated and low gossypol cotton seed meal (CSM) in layer production this study was carried out. Three different trials (76x12x4; 32x6x3 and 88x10x6) were conducted by incorporation of CSM at various levels (0, 10, 15, 20; 0, 15, 20 and 0, 20, 40, 60, 80, 100) at various phases of production in practical layer diets. Experiment 1, 2 and 3 were conducted during 65–76, 48–60 and 1934 weeks of age, respectively. Egg production (EP), feed intake (FI), egg mass (EM), feed efficiency (FI/EM), egg weight (EW), body weight (BW) and egg shell defects (ESD) were recorded at every 28 d period. EP, FI, FE and ESD were not influenced by the feeding the CSM up to the maximum levels tested up to 20% (expt 1 and 2) or up to 80% of SBM replacement (24.04% CSM in exp 3) in layer diet. The EW, EM and BW increased with increase CSM levels in diet. The results of this study indicated that decorticated CSM can be incorporated up to 20% while decorticated and low gossypol CSM up to 24% in diet without affecting the egg production, feed efficiency and body weight in WL layers.Not Availabl

Design and development of flame reactor unit for carbon nanorods (CNRs) production

235-239A pilot scale flame reactor has been designed and developed successfully for producing carbon nanorods by using methane, acetylene as the source of carbon in the oxygen atmosphere under atmospheric conditions without catalyst. The present paper discuses the designing of the flame reactor and the studies carried out on the flame reactor for producing carbon nanorods using methane, acetylene and oxygen gas-system. The carbon nanorods produced using this reactor are in the range of 150-600 nm

Delaying of cataract through intervention of <i>Hemidesmus indicus</i> in STZ induced diabetic rats

<p><i>Hemidesmus indicus</i> (L.) R. Br. was extensively used as hypoglycaemic agent and significance of this plant on secondary complications of diabetes remained unknown. The present study was to investigate the anti-cataractous activity of <i>H. indicus</i> against streptozotocin (STZ)-induced diabetic cataract in rodent model. Root extracts have been prepared and tested for inhibition of rat lens aldose reductase (AR) activity. In addition, its pharmacological potential has been investigated in STZ-induced diabetic cataract. Methanol extract of <i>H. indicus</i>-inhibited AR activity <i>in vitro</i> decreased the blood glucose levels, inhibited the AR activity and delayed the onset and progression of cataract in a dose-dependent manner in <i>in vivo</i> and the antioxidant markers have been normalised. Our results demonstrate that <i>H. indicus</i> has decrease the osmotic stress by inhibiting the AR activity and prevented the loss of antioxidants and delayed the progression of diabetic cataract in STZ-induced diabetic rats.</p

Synthesis and bioactivity evaluation of new phenyl <i>N,N′-</i>phenylphosphorodiamidates

<p></p> <p>A series of new biologically active phenyl N,N<b>^′-</b>phenyl phosphorodiamidates were synthesized by reacting phenyl phenylphosphoramidochoridate with various amines. All the newly synthesized compounds <b>3a-j</b> were tested for their antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydrogen peroxide (H₂O₂) and nitric oxide (NO) methods. In all the three methods the compounds <b>3c</b> (phenyl N-(6-methoxy-1,3-benzothiazol-2-yl)-N′-phenyl-phosphorodiamidate) and <b>3e</b> (phenyl N-(5-ethyl-1,3,4-thiadiazol-2-yl)-N′-phenylphosphorodiamidate) showed good radical scavenging activity.</p
