1-Chloro-4-(3,4-dichloro­phen­yl)-3,4-dihydro­naphthalene-2-carbaldehyde

The title compound, C17H11Cl3O, was synthesized via the Vilsmeier–Haack reaction. The dihydro­naphthalene ring system is non-planar, the dihedral angle between the two fused rings being 10.87 (13)°; it forms a dihedral angle of 81.45 (10)° with the dichloro­phenyl ring. The crystal structure features inter­molecular C—H⋯O hydrogen bonds

Investigation of deformation of the cornea during tonometry using FEM

A three dimensional finite element model of the human eye is developed to evaluate the force which will be applied over the surface of cornea during tonometry and gonioscopy tests. The standard tonometers and gonioscopy experiences deformation from 0.5mm to 3mm of the cornea is adopted during both point contact and boundary contact on the surface of the cornea. The results demonstrate the maximum force experienced by the tonometer with point contact at the center of the cornea for the maximum possible deformation of the cornea during tonometry. The study also analyzes for the force experienced by the tonometer or goniolens with boundary layer contact for the defined deformation of the cornea along the direction from cornea towards the retina

TIRSPEC : TIFR Near Infrared Spectrometer and Imager

We describe the TIFR Near Infrared Spectrometer and Imager (TIRSPEC) designed and built in collaboration with M/s. Mauna Kea Infrared LLC, Hawaii, USA, now in operation on the side port of the 2-m Himalayan Chandra Telescope (HCT), Hanle (Ladakh), India at an altitude of 4500 meters above mean sea level. The TIRSPEC provides for various modes of operation which include photometry with broad and narrow band filters, spectrometry in single order mode with long slits of 300" length and different widths, with order sorter filters in the Y, J, H and K bands and a grism as the dispersing element as well as a cross dispersed mode to give a coverage of 1.0 to 2.5 microns at a resolving power R of ~1200. The TIRSPEC uses a Teledyne 1024 x 1024 pixel Hawaii-1 PACE array detector with a cutoff wavelength of 2.5 microns and on HCT, provides a field of view of 307" x 307" with a plate scale of 0.3"/pixel. The TIRSPEC was successfully commissioned in June 2013 and the subsequent characterization and astronomical observations are presented here. The TIRSPEC has been made available to the worldwide astronomical community for science observations from May 2014.Comment: 20 pages, 21 figures, 2 tables.

Estimation of Serum Micronutrient Levels and The Possible Risk Of Oral Cancer And Premalignancy

Abstract; The oral cancer is one of the most prevalent type of cancer worldwide. It is invariably linked to lifestyle habits like alcohol consumption, cigarette smoking and poor nutritional status. This apart, the role of micronutrients in oral carcinogenesis still remains less understood. So the study was undertaken to assess the micronutrient levels of oral cancer and precancerous patients.The estimation of Haemoglobin showed there was no significant difference between controls, premalignancy cases and in cancerous conditions. Zinc and copper level levels were significantly lower in cases than in controls .There is a positive correlation between serum iron and selenium level and oral cancer patients, yet we didn't find significant increase in serum iron level either in precancerous or oral cancer patients. This study may indicate that very high or low levels of micronutrients associated with oral carcinoma. Yet moderate amount of micronutrients in diet may have protective effect on oral carcinoma which requires further research in these lines

SYNTHESIS, AB INITIO STRUCTURE DETERMINATION, AND CHARACTERIZATION OF MANGANESE(III) PHENYL PHOSPHONATES

ABSTRACT , space group P1, and Z ϭ 2. The final agreement factors were R WP ϭ 12.8%, R P ϭ 9.1%, and R F ϭ 3.2%. There are 22 non-hydrogen atoms in the asymmetric part of the unit cell, and the positional parameters were refined with the help of soft constraints. The octahedral manganese coordination spheres are distorted due to the Jahn-Teller effect. The structure of this organic-inorganic compound is layered. The thermal behavior of Mn(HO 3 PC 6 H 5 )(O 3 PC 6 H 5 )⅐H 2 O was studied and its thermal decomposition product was identified. © 1998 Elsevier Science Lt
