On January 19, 1993, a very bright bolide (peak magnitude −23) crossed the sky of Northern Italy, ending with an explosion approximately over the town of Lugo (Emilia Romagna, Italy). The explosion (14 kton of energy) generated shock waves which were recorded by six local seismic stations. A reanalysis of the available data leads us to the hypothesis that the meteoroid was a porous carbonaceous...
خاک به عنوان اصلی ترین بستر تولید محصولات غذایی مطرح است. این بستر مهم به علل مختلف و به اشکال گوناگون و در مقادیر متفاوت در سراسر جهان رو به فرسایش و نابودی است. متأسفانه در کشور ما و به خصوص در استان گلستان به علت شرایط اقلیمی، پستی و بلندی، خاک و نوع کاربری اراضی زوال این جزء مهم اکوسیستم بیشتر می باشد. در این راستا یکی از مهمترین اقداماتی که باید صورت پذیرد، مطالعه کمی و کیفی این پدیده مخرب...
Ocean Drilling Program Leg 210 was devoted to studying the history of rifting and postrift sedimentation in the Newfoundland–Iberia rift. Drilling was conducted in the Newfoundland Basin along a transect conjugate to previous drilling on the Iberia margin (Legs 149 and 173). This was the first time that deep-sea drilling has been conducted on both sides of a nonvolcanic rift in order to underst...

Analysis of the roles of the short chain fatty acid receptor, free fatty acid 3 receptor (FFA3), has been severely limited by the low potency of its endogenous ligands, the crossover of function of these on the closely related free fatty acid 2 receptor, and a dearth of FFA3-selective synthetic ligands. From a series of hexahydroquinolone-3-carboxamides, we demonstrate that 4-(furan-2-yl)-2-met...
