in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
in iran we already use laminate tubes only in cosmetics industry. laminate tube manufacturers via using the most modern technology of the world, faced with the laminate tube market being saturated in cosmetics industry for packaging the cosmetic creams and toothpaste. but considering the great food market and therefore laminate tube features such as beautiful packaging, ease of use for the fina...
دیوارهای خاک مسلّح ، دیوارهای مقرون به صرفه ای هستند که امروزه کاربرد زیادی در پروژه های عمرانی دارند. پایداری دیوارهای خاک مسلّح از دو جنبه پایداری خارجی و پایداری درونی مدّ نظر است. پایداری درونی دیوار شامل پایداری در برابر گسیختگی و بیرون کشیدگی مسلّح کننده ها می باشد. جهت بررسی پایداری درونی دیوار بایستی نیروی مسلّح کننده ها محاسبه شود. برای محاسبه این نیروها روش های مختلفی ارائه شده که در این ت...
the purpose of this study was the relationship between problem – solvi ability with fdi cognitive style of students.the research method was correlation method. for data analysis pearson test was used. statistical society in this research was all the students of alligoodarz city in 1391-92 year.to sampling of statiscal population was used sampling multi-stage random the size of sample selected 2...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
The liver of the guinea pig was shown (1, 2) to contain two enzymes which catalyze the dehydrogenation of testosterone. One is located in the particulate fraction and specifically requires diphosphopyridine nucleotide as hydrogen acceptor; the other, present in the fraction of guinea pig homogenate not sedimented by 24,500 X g for 60 minutes, specifically requires triphosphopyridine nucleotide ...
Current JAK2 inhibitors used for myeloproliferative neoplasms (MPN) treatment are not specific enough to selectively suppress aberrant JAK2 signalling and preserve physiological JAK2 signalling. We tested whether combining a JAK2 inhibitor with a series of serine threonine kinase inhibitors, targeting nine signalling pathways and already used in clinical trials, synergized in inhibiting growth ...
The rapid rate of growth and multiplication of the Ehrlich mouse ascites carcinoma cells (6) indi cates the need for large amounts of nutrients for the production of protoplasm and the acquiring of energy for those synthetic processes. Recently, Christensen and Riggs (2) and Christensen, Riggs, Fischer, and Palatine (3) have reported the strik ing ability of this tumor cell to concentrate amino...
Examination of the product of affinity labeling of delta 5-3-ketosteroid isomerase (EC 5.3.3.1) of Pseudomonas testosteroni by the suicide substrate [7-3H]5,10-secoestr-5-yne-3,10,17-trione has demonstrated that the steroid becomes bound by an acid- and base-labile linkage to an active-site peptide representing residues 55-58 (H2N-Tyr-Ala-Asn-Ser-CO2H) of the primary structure (Penning, T. M., ...
Introduction Intake of broccoli sprouts, a rich source of the glucosinolate glucoraphanin, has been associated with decreased incidence, multiplicity, and tumor growth in animal cancer models.1-3 In 1992, Paul Talalay, MD, and colleagues at Johns Hopkins University identified the isothiocyanate, sulforaphane, a biologically active metabolite of glucoraphanin, as the compound in broccoli respons...
