Abstract The sol–gel method is used to prepare the nanocomposites ZF/RO (ZF = ZnFe 2 O 4 , RO CdO, NiO, Ga 3 SnO and TiO ). XRD showed that nanocomposite' crystal structure contained many phases, lattice properties size of ZF were affected by presence traces. All samples have surfaces resemble nanoflakes vary in based on SEM pictures; however, ZF/Cd sample has a nanotube microstructure. ESR VSM...

Little is known about mechanisms of regulation of cysteine dioxygenase (CDO), γ-glutamylcysteine synthetase (GCS), and cysteine-sulfinate decarboxylase (CSDC) in response to diet. Enzyme activity and Western and Northern or dot blot analyses were conducted on liver samples from rats fed a basal low-protein diet or diets with graded levels of protein or methionine for 2 wk. Higher levels of CDO ...

A thin buffer layer of cadmium oxide (CdO) was used to enhance the optical and electrical properties of indium tin oxide (ITO) films prepared by an electron-beam evaporation technique. The effects of the thickness and heat treatment of the CdO layer on the structural, optical and electrical properties of ITO films were carried out. It was found that the CdO layer with a thickness of 25 nm resul...

This research work investigates the theoretical foundations and computational aspects of constructing optimal bespoke CDO structures. Due to the evolutionary nature of the CDO design process, stochastic search methods that mimic the metaphor of natural biological evolution are applied. For efficient searching the optimal solution, the nondominating sort genetic algorithm NSGA-II is used, which ...

In this paper we use dynamic copulas method to price a CDO. We apply GOF test and binary segmentation procedure to detect the change of copula function. According to the result of the change point, we divide the time series into nine stages. In each stage, we use the best copula function to describe the default correlation. Our empirical results show that in different time period, the best copu...

Credit ratings assigned by rating agencies to structured credit products have played an important role in the development of the structured credit market, which has been cast into the limelight by the recent credit crisis. This study aims at clarifying some misconceptions related to CDO ratings, their interpretation and their use. We first describe the rating approaches used by major agencies f...

کارائی بلوغ آزمایشگاهی تخمک(ivm) ، با وجود تلاش های گسترده، همچنان پائین است. نظر به اینکه با کشت تخمک، تقسیم میوز به صورت خود به خودی از سر گرفته می شود، فرض بر آن شد که با جلوگیری از میوز پیش از بلوغ در شرایط آزمایشگاهی، تخمک توانائی تکوین بیشتری را کسب می کند. تخمک های ژرمینال وزیکول (gv) موش آماده شده با گنادوتروپین سرم مادیان آبستن (pmsg) جمع آوری و به دو گروه تخمک های همراه مجموعه کومولوس...

Cadmium Oxide (CdO) nanoparticles were prepared by precipitation method using Cadmium acetate and ammonia solution. Presence of chemical species, were verified by Fourier Transform Infra Red (FTIR) Spectrum. From X-Ray Diffraction (XRD) spectrum the particle size, d-spacing value and structure of the nanoparticle were analysed. Size of the nanoparticles and the elemental composition were detect...

template synthesis is a powerful method for the preparation of nanoscale materials with specific size and shape. cadmium oxide (cdo) nanoparticles were synthesized by using sodium dodecyl sulfate (sds), cd(oac)2.2h2o and sodium hydroxide as starting materials. the sample was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem). the xrd pattern proves that the final produ...

In Neurospora, metabolic oscillators coexist with the circadian transcriptional/translational feedback loop governed by the FRQ (Frequency) and WC (White Collar) proteins. One of these, a choline deficiency oscillator (CDO) observed in chol-1 mutants grown under choline starvation, drives an uncompensated long-period developmental cycle ( approximately 60-120 h). To assess possible contribution...
