گیاه مرزه رشینگری متعلق به خانوادهی نعناعیان یکی از گونه های مرزه انحصاری ایران است که به دلیل داشتن کارواکرول بالا در اسانس در صنایع دارویی استفاده آن رو به گسترش می باشد. برنامه اهلی سازی و اصلاح رقم مناسب از این گیاه جهت کشت از چند سال پیش در ایران آغاز شده است. در غربالگری اولیه 1200 جمعیت از 12 رویشگاه و کشت در شرایط محیطی یکسان، نهایتا تعداد 58 همگروه برتر از این گیاه شناسایی شدند. در این...
Effects of Religiosity on Social Behaviour: Experimental Evidence from a Representative Sample of Spaniards This study explores the effect of several personal religion-related variables on social behaviour, using three paradigmatic economic games: the dictator (DG), ultimatum (UG), and trust (TG) games. A large carefully designed sample of a Spanish urban adult population (N=766) is employed. F...
We consider fourteen kinds of two-dimensional triangle hypersurface singularities, and consider what kinds of combinations of rational double points can appear on small deformation fibers of these triangle singularities. We show that possible combinations can be described by Gabriélov graphs and Dynkin graphs. 1. Review of results by Russian mathematicians In this article we assume that every v...
According to surveys, around a quarter of Americans expect the world to end as prophesied by the Bible during their own lifetime. This paper undertakes the rst test of whether these end times beliefs a¤ect economic behavior, using a 10-year panel of house price data across 363 Metropolitan Statistical Areas (MSAs). It identi es a causal e¤ect by interacting a time-varying proxy for the perce...
The first few hundred Myrs at $z>10$ mark the last major uncharted epoch in history of Universe, where only a single galaxy (GNz11 $z\approx11$) is currently spectroscopically confirmed. Here we present search for luminous galaxies with $JWST$/NIRCam photometry spanning $\approx1-5\mu$m and covering 49 arcmin$^{2}$ from public Early Release Science programs (CEERS GLASS). Our most secure candid...

First, suicide missions receive significantly more coverage, which could explain their increased popularity among terrorist groups. This result is further supported by Oaxaca-Blinder decompositions, su...
We construct a hierarchy of supersymmetric string theories by showing that the general N -extended superstrings may be viewed as a special class of the (N + 1)-extended superstrings. As a side result, we nd a twisted (N + 2) superconformal algebra realized in the N -extended string. e-mail address: [email protected] e-mail address: [email protected], [email protected] Permanent a...
