Two recent studies have shown that “cheap talk” is an effective means of eliminating positive hypothetical bias in experimental and field-auction settings. We further investigate the ability of cheap talk to mitigate positive hypothetical bias in a contingent-valuation phone survey administered to over 4,000 households. Positive hypothetical bias is detected in our data by contrasting revealed ...
ماهی کپور معمولی (cyprinus carpio) می تواند یکی از منابع تهیه ماده خام اولیه محصولات شیلاتی نظیر سوریمی جهت تولید محصولات آماده مصرف باشد. با توجه به اینکه اختصاصات بافتی محصولات تولید شده از سوریمی، بستگی به توانایی تولید ژل آن دارد و از طریق آمادگی اولیه خمیر ماهی برای پخت نهایی (قوام یابی) می توان ژل مقاوم تر تولید کرد، در این تحقیق اثر دما و زمان انعقاد (قوام یابی) بر خواص تولید ژل سوریمی ک...
Bu çalışma kapsamında farklı sonlu elemanlar yaklaşımları kullanılarak on katlı betonarme bir binanın radye temel kalınlıkları ve beton sınıfları değişiminin oturma üzerine etkisi araştırılmıştır. İlk yaklaşımda yapı düşey yükleri, sistemi alan yükü olarak etkitilmiştir. İkinci ise zemin birlikte modellenerek üst yükleri zemine doğrudan aktarılmıştır. İki yaklaşımla elde edilen modellerde 80-10...
Suppose V and U are two independent mean zero random variables, where V has an asymmetric distribution with two mass points and U has a symmetric distribution. We show that the distributions of V and U are nonparametrically identified just from observing the sum V +U , and provide a rate root n estimator. We illustrate the results with an empirical example looking at possible convergence over t...
We examine the dissent voting record of the Bank of England Monetary Policy Committee (MPC) in its first decade. Probit estimates indicate the impact of career experience on dissent voting is negligible, whereas the impact of forecast inflation is pronounced. In addition to finding a role for dynamics, we also find a role for unobserved heterogeneity in the form of member-specific fixed-effects...
This study examines the proper estimation of trip demand and economic benefits for visitors to recreation sites when past-season trip information is elicited from travelers intercepted on-site. We show that the proper weighting of past season counts is different from the standard on-site correction appropriate for current-season counts. We find that for our sample of lake visitors relatively st...
Here, we report a synthesis of the lower half C21-C40 fragment of the shellfish toxin, azaspiracid-1. The C28-C40 fragment was synthesized by a coupling between the C28-C35 epoxide and the C36-C40 dithioacetal anion, followed by the HI-ring spiroaminal formation. An aldehyde corresponding to the C28-C40 fragment was then coupled with the C21-C27 allylic stannane by using InCl3. Finally, the FG-...
در این پژوهش تاثیرات افزودن نانو لولههای کربنی چند دیواره با قطر 15-5 نانومتر معلق در آب با درصد وزنی (25/0-04/0) بر ضریب انتقال حرارت بررسی شده است. این کار توسط یک مبدل حرارتی دولولهای با پوسته غیر فلزیPVDF در حالت جریان غیر همسو انجام شده و به این منظور ابتدا ویسکوزیته و ضریب هدایت حرارتی نانوسیال در دما های (°C35 و °C50) به صورت آزمایشگاهی تعیین شد. با افزایش دما، غلظت و سرعت جریان نانو س...
The effect of bisulfite-induced C + U transitions on the aminoacylation of highly purified Escherichia coli tRNAt,’& has been studied. On treatment with 3.2 M NaHS03 at 25 “C and pH 5.8, C + U transitions occurred at 4 of the 21 cytosine residues during the first 16 h. After about 12 h, 2 additional unidentified residues begin to react. From these data and theoretical consideration, we conclude...
Calcium- and integrin-binding protein 1 (CIB1) is involved in the process of platelet aggregation by binding the cytoplasmic tail of the alpha(IIb) subunit of the platelet-specific integrin alpha(Iib)beta(3). Although poorly understood, it is widely believed that CIB1 acts as a global signaling regulator because it is expressed in many tissues that do not express integrin alpha(Iib)beta(3). We ...
