Microwave Kinetic Inductance Detectors, or MKIDs, have proven to be a powerful cryogenic detector technology due to their sensitivity and the ease with which they can be multiplexed into large arrays. A MKID is an energy sensor based on a photon-variable superconducting inductance in a lithographed microresonator, and is capable of functioning as a photon detector across the electromagnetic spe...

     A special type of silica-based columns has been recently introduced into the market which is called narrow-bore columns. They have lower internal volume than the standard high-performance liquid chromatography (HPLC) columns and thus reduce the solvent consumption by almost 80%.    A simple, accurate and environmentally friendly reversed phase- HPLC (RP-HPLC method) which could be used in ...

Observing the ultraviolet (UV) sky for time-varyiable phenomena is one of many exciting science goals that can be achieved by a relatively small aperture telescope in space. The Near Ultraviolet Transient Surveyor (NUTS) wide-field (3∘) imager with photon-counting detector near-UV (NUV, 200 – 300 nm), to flown on an upcoming satellite mission. It has Ritchey–Chrétien (RC) design correction opti...

phase sensitive detector described here has two principal applications: a- to produce a d.c out put proportional to- the amplitude of an incoming a,c signal and indicate, by the outut polarity, the phase of the signal with respect to an internal reference. b- to detect the presence of a signal of known phase and frequency which would otherwise be lost in «background noise» and to measure its am...

in this paper a new algorithm is presented for coherent radar detection of targets, when distribution of the interference (clutter and noise) is non-gaussian. the neyman-pearson criterion is used for optimal detection and several successive received samples from a radar range cell are used for detection in the same cell. on the basis of recent empirical evidences, the interference distribution ...

Amorphous solid dispersions (ASDs) are a promising formulation approach for poorly soluble active pharmaceutical ingredients (APIs), because they ideally enhance both dissolution rate and solubility. However, the mechanism behind this is not understood in detail. In the present study, we investigated the supramolecular and the nano/microparticulate structures that emerge spontaneously upon disp...

Abstract Characterizing the atmospheres of planets orbiting M dwarfs requires understanding spectral energy distributions over planetary lifetimes. Surveys like MUSCLES, HAZMAT, and FUMES have collected multiwavelength spectra across type’s range T eff activity, but extreme ultraviolet (EUV, 100–912 Å) flux most these stars remains unobserved because obscuration by interstellar medium compounde...

Most organic ultraviolet filters are very lipophilic and some of them difficult to quantify in the environment. This article describes an optimization method for quantification these compounds sand samples with diverse compositions. The standard additions was used. search a unique high-performance liquid chromatography analyze all along optimal detection conditions presented detail. best extrac...

Lapatinib is a small molecule, heterocyclic quinazoline derivative. The drug used for targeted therapy of patients with breast cancer, in which there overexpression the human epidermal growth factor receptors (HER/ErbB). This review devoted to studying modern instrumental methods qualitative and quantitative analysis lapatinib, can be both quality control standardization (of bulk pharmaceutical...

a special type of silica-based columns has been recently introduced into the market which is called narrow-bore columns. they have lower internal volume than the standard high-performance liquid chromatography (hplc) columns and thus reduce the solvent consumption by almost 80%.    a simple, accurate and environmentally friendly reversed phase- hplc (rp-hplc method) which could be used in fast ...
