Sensitizing Efficiency of Some Added Metal Salts on the Thermal and Explosive Characteristics of Hydrazenium Monoperchlorate and Hydrazenium Diperchlorate

Sensitivity to heat, impact and friction of hydrazenium-monoperchlorate and hydrazenium-diperchlorate have been investigated and the sensitizing efficiency of some added metal salts evaluated. The thermal sensitizing efficiency of the additives follow the order CuCrO/sub 4/ > CuCl/sub 2/ >NiO > Fe/sub 2/O/sub 3/ > MgO. The activation energy values obtained from explosion delay time are comparable with the values reported for thermal decomposition studies and are close to the activation energy value for thermal decomposition studies and are close to the activation energy value for thermal decomposition of anhydrous perchloric acid. The F of I values for these compounds are in the range reported for common initiatory explosives and are of the same order as that for mercury fulminate

The Temperature Evolution of the Out-of-Plane Correlation Lengths of Charge-Stripe Ordered La(1.725)Sr(0.275)NiO(4)

The temperature dependence of the magnetic order of stripe-ordered La(1.725)Sr(0.275)NiO(4) is investigated by neutron diffraction. Upon cooling, the widths if the magnetic Bragg peaks are observed to broaden. The degree of broadening is found to be very different for l = odd-integer and l = even-integer magnetic peaks. We argue that the observed behaviour is a result of competition between magnetic and charge order.Comment: 3 figure

Performance of Signal Strength prediction in Data transmission Using Elliott wave Theory

The article describes an algorithm for predicting the future signals with the aid of past signal samples. In the real signal processing environment, the amplitude and unsystematic in phase signal are lead to more complex to estimation the signal, thereby, customer service is enhanced by forecast. The forecast of financial marketplace are usually done by means of Elliot wave theory. In this article possibility and applicability survey of the EW Theory is proposed in the paper towards the power of the signal forecast. In nature, the EW theory has free declining environment, and also uncomfortable based on the customer and base station and height of the antenna. The proposed algorithm has tested in real life conditions, considering both, the pedestrian persons and the people travelling at 60 Km/Hr. Consequently, the predicted result incorporates the practical signal strength based on increasing distribution utility, signal to intervention noise ratio (SNR) and instability at their subsequent time. The end result of the algorithm shows 68% of successful prediction

Spin gaps and magnetic structure of NaxCoO2

We present two experiments that provide information on spin anisotropy and the magnetic structure of NaxCoO2. First, we report low-energy neutron inelastic scattering measurements of the zone-center magnetic excitations in the magnetically ordered phase of Na0.75CoO2. The energy spectra suggest the existence of two gaps, and are very well fitted by a spin-wave model with both in-plane and out-of-plane anisotropy terms. The gap energies decrease with increasing temperature and both gaps are found to have closed when the temperature exceeds the magnetic ordering temperature T_m~22 K. Secondly, we present neutron diffraction studies of Na0.85CoO2 with a magnetic field applied approximately parallel to the c axis. For fields in excess of ~8T a magnetic Bragg peak was observed at the (0,0,3) position in reciprocal space. We interpret this as a spin-flop transition of the A-type antiferromagnetic structure, and we show that the spin-flop field is consistent with the size of the anisotropy gap.Comment: 9 pages, 7 figure

Magnetic & Spectral Studies on Ni(II) & Cu(II) Complexes of N-(Salicylidene)phenylhydrazine

536-53

N-{1-[(3-Bromo­prop­yl)amino­carbon­yl]eth­yl}-2-(2-nitro­benzene­sulfonamido)propionamide

In the title compound, C15H21BrN4O6S, all three NH groups are involved in inter­molecular N—H⋯O inter­actions which, together with two inter­molecular C—H⋯O contacts, lead to a continuous anti­parallel β-sheet structure. There are no π–π inter­actions between mol­ecules, and two C—H⋯π inter­actions primarily govern the linkage between sheets

PLASMA TRACE ELEMENT STATUS IN BETA-THALASSEMIA TRAIT PATIENTS

Objective: The study aims to evaluate the plasma trace element status in beta-thalassemia trait (BTT) patients and demonstrate the correlation between trace elements and hemoglobin (Hb)-A1, HbA2, and HbF.Methods: The study population consisted of 20 normal individuals and 40 patients with BTT aged between 25 and 55 years of both the sex. Hemoglobin variant analysis was performed in blood samples using cation exchange high-performance liquid chromatography. Patients were labeled as beta-thalassemia trait only if they had HbA2 >3.5% or HbF >2.0%. Plasma zinc was estimated by atomic absorption spectrometry, copper by bathocuproine disulfonate method, and iron by ferrozine method spectrophotometrically. Data were analyzed statistically by Student's t -test and Pearson's correlation using software SPSS version 20. p<0.05 was considered statistically significant.Results: Plasma zinc and copper decreased significantly in BTT patients compared to healthy controls. There was an apparent decrease in plasma iron in these patients. Degree of decline in zinc (p<0.001) was much greater than that of copper (p<0.04). Moreover, there was significant elevation of copper-zinc ratio and iron-zinc ratio (p<0.001) in BTT patients compared to controls. Both HbA1 and HbA2 correlated positively with both copper and iron. Interestingly, HbF showed negative correlation with all the three trace elements in BTT patients.Conclusion: The study highlights marked deficiency of plasma trace elements, hence, the need for periodic assessment and prompt administration of these micronutrients to reduce the complications in BTT patients. Further, ratios are more valuable markers in the determination of trace element status than individual elements
