Mid-infrared virtually imaged phased array spectrometer for rapid and broadband trace gas detection.
We present and characterize a two-dimensional (2D) imaging spectrometer based on a virtually imaged phased array (VIPA) disperser for rapid, high-resolution molecular detection using mid-infrared (MIR) frequency combs at 3.1 and 3.8 μm. We demonstrate detection of CH4 at 3.1 μm with >3750 resolution elements spanning >80 nm with ~600 MHz resolution in a <10 μs acquisition time. In addition to b...
Recently, a high frame rate (HFR) imaging method based on limited diffraction beam (LDB) theory has been developed. In this method, a twodimensional (2D) or three-dimensional (3D) image is constructed with a single plane wave transmission and thus a theoretical frame rate of 3750 frames/second can be obtained for biological soft tissues at a depth of about 200 mm. Because a plane wave is used t...
Now, the role of cooperatives in socio-economic development, equipping capital and thoughts, and then changing them to effective powers in the process of socio-economic development, distributing the benefits of this process in a more equitable manner among people specially the poor and low-income masses, is obvious for all of us. For determining the level of cooperative success to achieve their...
We present the results of a GHRS program to monitor the absorption lines in the spectrum of the Seyfert 1 galaxy NGC 4151 caused by outflowing gas from the nucleus. Although we see subtle changes over the four year period in the GHRS spectra of the broader of the absorption features, the wavelength constancy of all the features is remarkable. The limits on the secular acceleration suggest that ...
El objetivo de este artículo es considerar cómo la situación vulnerabilidad los y las trabajadoras informales ciudad Cali se ha reflejado en pandemia. Para esto tiene cuenta perspectiva Robert Castel, pues según el autor situaciones pueden devenir o contener dinámicas exclusión social. Así, toman como componentes esas contradicciones inherentes a afiliación desafiliación sistemas salud pensión.
This study presents data on the IR spectra of kaolinite at a moisture 26% and after drying. The preparation moistened samples was made with distilled water, solutions NaCl limiting 50% concentrations temperature 21 °C. To experimentally evaluate effect interaction between liquid water sorbing basal surfaces profile spectrum bands, were additionally studied. Comparison band profiles in wavenumbe...
To determine the most suitable sowing date on yield and fruit characteristics of greenhouse tomato, this research was carried out in Larestan region of Fars province in Iran in 2010. The experimental factors included three sowing dates (06 September, 20 September and 04 October) and four greenhouse tomato cultivars (Feroun, Chelbas, Ergon and Uksel) were arranged as factorial in randomized comp...
تأثیر پسماند گندم و تراکم آفتابگردان بر زیست توده و ارتفاع تاج پوشش علف های هرز، طی آزمایشی در سال 1386 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه بیرجند در قالب طرح بلوک های کامل تصادفی به صورت فاکتوریل و در 3 تکرار انجام شد. تیمار عبارت بودند از: 5 سطح مختلف پسماند گندم شامل صفر، 1250،2500، 3750 و 5000 کیلوگرم در هکتار بعلاوه تیمار سوزاندن 5000 کیلوگرم در هکتار پسماند گندم (سطوح عامل اول) و سه...
