Dendrostellera lessertii (Thymelaeaceae) is a toxic plant that grows in parts of Iran. The anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-HK), have been established using several cancer cell lines. Methods: In a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...
One of the main problems in oil recovery via the gas injection is the formation of hydrates in thelines. In order to prevent the formation of hydrate in these lines, which leads to the blockage andsometimes explosion, at first, the equilibrium formation conditions must be determined and then toprevent its formation by changing the thermodynamic conditions or by adding the inhibitors. In thisres...
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...
The model microfield method has been applied to the broadening of spectral lines emitted by multiply charged hydrogenic ions in pure and binary mixtures. Special attention is paid to the calculation of the ionic microfield distribution function. Extensive comparisons with other theoretical results are performed. Fine structure effects are shortly discussed. This
wheat is grown on 6.2 million hectares under different agr-climate conditions in iran. of 6.2 million hectares irrigated wheat, khazar warm humid climate regions (gorgan, mazandaran and moghan) with 350 thousand hectares are the most important wheat growing areas of the country. productive and rich lands, high rainfalls and favorable temperature and light in these regions provide good condition...
Twelve reference strains of mycoplasma and acholeplasma previously reported to have been recovered from cattle were tested against hyperimmune rabbit serum by counterimmunoelectrophoresis. This technique detected antigen by the formation of precipitin lines with antibody within 1 h and promises to be a useful technique for detecting and identifying mycoplasma isolates in either pure or mixed cu...
This paper presents an extension to our knowledge of ∆v = 1 and 2 bands carbon monoxide in the ground state, measured by Fourier transform infrared spectroscopy glow discharge formamide-nitrogen mixture. Lines declared are up v 30 for 24 band, use both InSb MCT detectors, which have not been laboratory before. Dunham parameters obtained fitting lines presented as well comparison other authors. ...
We have developed a technique for the printing of fine copper lines using solutions of a metal organic precursor, copper hexanoate (CuHex). Liquid ribbons 500 μm wide, deposited on a glass substrate either by ink-jetting or capillary writing, are observed to split into two or four finer lines depending on the solution concentration. Surface profiles indicate that the thickness, width and number...
PURPOSE High-throughput chemosensitivity testing of low-passage cancer cell lines can be used to prioritize agents for personalized chemotherapy. However, generating cell lines from primary cancers is difficult because contaminating stromal cells overgrow the malignant cells. EXPERIMENTAL DESIGN We produced a series of hypoxanthine phosphoribosyl transferase (hprt)-null immunodeficient mice. ...
We study the two-dimensional, time-dependent magnetohydrodynamics (MHD) of radiation-driven winds from luminous accretion disks initially threaded by a purely axial magnetic field. The radiation force is mediated primarily by spectral lines and is calculated using a generalized multidimensional formulation of the Sobolev approximation. We use ideal MHD to compute numerically the evolution of Ke...
