در این مطالعه، اثر دو روش تلقیح (شناورسازی و اسپری) و دو سویه Agrobacterium rhizogenes (A13 و GMI9534) برای القاء ریشههای مویین روی ریزنمونههای مختلف (هیپوکوتیل، کوتیلدون، برگ و گره ساقه Teucrium chamaedrys L. بررسی شد. سویه GMI9534 نتوانست در هیچیک از ریزنمونهها ریشه مویین القاء کند، در حالیکه سویه A13 فقط قادر به القاء ریشههای مویین روی ریزنمونههای برگ و گره ساقه بود. البته روش تلقیح شن...
us: This inquiry seeks to establish the importance of the critiques leveled by Thorstein Veblen and Tony Lawson against the orthodox economics. In order to advance this point this inquiry advances the notion that Neoclassical school and its sub school known as marginal utility theory are constructed upon shaky philosophical and methodological foundations that include the hedonistic conception o...
The &as if ' view of economic rationality defends the pro"t maximization hypothesis by pointing out that only those "rms who act as if they maximize pro"ts can survive in the long run. Recently, the problem of arriving at a logically consistent de"nition of rational behavior in games has shown that one must sometimes study explicitly the evolutionary processes that form the basis of this view. ...
This study investigated the association between HLA antigens and inflammatory bowel disease in 65 Iraqi patients (50 ulcerative colitis, 15 Crohn disease) compared with 67 matched controls. At HLA class I region, the patients showed significantly increased frequencies of A9 and B41 and a decrease of A11. Similar results were found when the clinical types were considered separately, except for A...
A challenge for HIV-1 immunogen design is the difficulty of inducing neutralizing antibodies (NAbs) against neutralization-resistant (tier 2) viruses that dominate human transmissions. We show that a soluble recombinant HIV-1 envelope glycoprotein trimer that adopts a native conformation, BG505 SOSIP.664, induced NAbs potently against the sequence-matched tier 2 virus in rabbits and similar but...
Perspectives from the Happiness Literature and the Role of New Instruments for Policy Analysis After having been ignored for a long time by economists, happiness is becoming an object of serious research in 21 century economics. In Section 2 we sketch the present status of happiness economics. In Section 3 we consider the practical applicability of happiness economics, retaining the assumption ...
A clone encoding the F41 f imbnal sub-unit gene from E coli B41, was isolated from an B1BL3 library using an oligonucleotide based on the published N-termlnal amino acid sequence (1). The DNA sequence of an t I66bp fragment revealed an open reading frame encoding a protein of 277 amino acids including a 22 amino acid leader sequence (dash underlined). This corresponds to a mature protein of 290...
