Prediction of Overpressure from Finite Volume Explosions

Tri-nitro toluene (TNT) equivalence is not a good criterion for evaluating the practically encounted nonideal blast waves during ignition and in explosion-safety problems. A theoretical model which shows the trends related to the effects of source volume and energy time release on blast wave strength is discussed. A slower energy release and a larger source volume are shown to be necessary to reduce the blast effects

A method of cleaning microscope slides for their repeated use in the examination of sputum for tubercle bacilli

The difficulty with which acid-fast bacilli are removed from glass slides has led several workers to recommend that only new slides should be used for the preparation of smears to demonstrate the presence of tubercle bacilli (Wilson and Miles, 1955; Baker, Silverton and Luckock, 1957; Cruickshank, 1960). This practice cannot easily be followed in many countries where microscope slides of good quality are expensive and often difficult to obtain. The experiment reported here was under-taken to determine whether a modern method of cleaning, incorporating the use of a detergent, can remove the tubercle bacilli from glass slides on which they have been heat-fixed and stained

Linear and Nonlinear Optical Properties of Mn doped Benzimidazole Thin Films

In the present work, the Mn doped benzimidazole (BMZ) thin films were prepared by simple chemical bath deposition technique. The material was directly deposited as thin film on glass substrates and the metal concentration in the solution was varied in weight percentage in order to investigate the dopant effect on the properties of thin films. Similarly, the Mn doped BMZ films were deposited in different solution temperature to study the effect of deposition temperature on the properties of thin films. The PXRD and FT-IR spectroscopy are used to study the structural and the presence of functional groups in the BMZ medium. Depending upon the solution temperature, thickness of the films varying from 0.6 to 1.2 {\mu}m and the optical transparency of the samples increases with the increasing temperature up to 50 {\deg}C. Second Harmonic Generation (SHG) efficiency of the films is measured for all the films. Third order nonlinear optical properties of the films were analyzed using Z-scan technique. The experimental results show that Mn doped BMZ films exhibits saturation absorption and negative nonlinearity.Comment: This has been presented in DAE 58th Solid State Symposium held at Thapar University, Patiala, Punjab, India. Will be published in AIP conference proceedings soo

Ordered reduced set successive detector for low complexity, quasi-ML MIMO detection

An Ordered Reduced Set Successive Detector (RSSD) for the V-BLAST spatial multiplexing scheme that uses a general two-dimensional non-uniform set partitioning for different symbols. The detector provides improved diversity and SNR gains at reduced complexity compared to a uniform set partitioning based detector. The detector can be used to reduce the complexity, with a small tradeoff in performance. Further, it is possible to obtain a quasi-ML performance using the disclosed detector at a reduced, yet fixed, complexity

4-[(E)-(4-Methyl­phen­yl)imino­meth­yl]phenol

In the title compound, C14H13NO, the two rings show significant deviation from coplanarity, with a dihedral angle between the two planes of 49.40 (5)°. The hy­droxy group is involved in an inter­molecular O—H⋯N hydrogen bond, forming an extended one-dimensional zigzag chain along (001)

4-Bromo-N-(4-hy­droxy­benzyl­idene)­aniline

In the title compound, C13H10BrNO, the benzene ring planes are inclined at an angle of 48.85 (17)°, resulting in a nonplanar mol­ecule. A characteristic of aromatic Schiff bases with N-aryl substituents is that the terminal phenyl rings are twisted relative to the HC=N plane. In this case, the HC=N unit makes dihedral angles of 11.1 (4) and 38.5 (3)° with the hy­droxy­benzene and bromo­benzene rings, respectively. In the crystal, the molecules are linked by O—H⋯N hydrogen bonds to form infinite (C8) chains along the b axis

N-[4-(2-Morpholino­eth­oxy)phen­yl]acetamide monohydrate

In the title compound, C14H20N2O3·H2O, the geometry about the morpholine N atom implies sp 3 hybridization. In the crystal, symmetry-related mol­ecules are linked by inter­molecular N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds, forming infinite chains along the b axis. The chain structure is further stabilized by intra­molecular C—H⋯O inter­actions

3-(1H-Benzimidazol-2-yl)-2-chloro-8-methyl­quinoline

Two independent mol­ecules of the title compound, C17H12ClN3, are present in the structure. The angle between the planes defined by the atoms of the benzimidazole unit and the quinoline unit are 45.2 (3) and 44.0 (3)°, indicating an essentially identical conformation for both mol­ecules. Each of the independent mol­ecules is linked with a symmetry equivalent by an inter­molecular N—H⋯N hydrogen bond involving the two benzimidazole N atoms, to form chains in the crystallographic c direction
