We use U.S. county-level data consisting of 3,058 observations, to study growth determination and measure the speed of income convergence. County-level data are particularly valuable for studying convergence because they allow us to study a sample with substantial homogeneity and exceptional mobility of capital, labor and technology without sacrificing the benefits of a large number of cross-se...
در این پژوهش از روش pcr-elisa با استفاده از ژن re، برای تشخیص حساسیت و اختصاصی بودن و نیز سنجش کمی بار انگلی در خون 15 رت آلوده شده با توکسوپلاسما گونده ای سویه rh استفاده گردید. در این روش پرایمرهای اولیگونوکلئوتیدی برای هدف گیری ژن re مربوط به تاکی زوئیت به طول bp138 انتخاب شده و برای تکثیر dna توکسوپلاسما گونده ای، از فرایند pcr و نشاندار کردن هم زمان محصول بدست آمده از آن با دیگوکسی ژنین اس...

We replicate 61 papers published three top journals from past decade (2011-2020) document several troubling patterns: (1) often miscalculate first...
in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...

OBJECTIVE The aim was to assess the causal influence of homocysteine on systolic and diastolic blood pressure (SBP and DBP, respectively...
This paper presents a new user-written STATA command called ivtreatreg for the estimation of five different (binary) treatment models with and without idiosyncratic (or heterogeneous) average treatment effect. Depending on the model specified by the user, ivtreatreg provides consistent estimation of average treatment effects both under the hypothesis of “selection on observables” and “selection...
