Abstract We present two robust and well‐dated paleomagnetic poles from upper Eocene Oligocene volcanics in the Urumieh‐Dokhtar magmatic arc, Central Iran. These place Iran ∼3.7°–3° of latitude south its position between ca. 40 23 Ma. Our new declination data indicate that block may have experienced a ∼11.6° clockwise rotation since Late Eocene. integrated our with retrodeformed margins Zagros c...

Abstract. We have developped a new method for the scheduling of astronomical automatic telescopes, in the framework of the autonomous TAROT instrument. The MAJORDOME software can handle a variety of observations, constrained, periodic, etc., and produces a timeline for the night, which may be modified at any time to take into account the specific conditions of the night. The MAJORDOME can also ...

Morphological differences between the adults of overwintering and non-overwintering generations of the sawfly Pristiphora leucopus (Nematinae) are described and illustrated, as well as characters that distinguish P. leucopus from the closely similar P. armata. In the basal hymenopteran lineages (‘Symphyta’), seasonal polyphenism is so far only definitely recorded in the Sterictiphorinae (Argida...

introduction subtropical high pressure is one of the main elements of the general circulation of the atmosphere. annual motion of the circulation plays an important role in movement path of pressure systems and westerlies. hence, large parts of the planet are affected directly and indirectly by this system. sometimes the high pressure called the subtropical high pressure belt. it’s shown as sev...

Introduction: Several craters on Mars are partially filled by material emplaced by post-impact processes. Populations of such craters include those in the circum-south polar cap region, in Arabia Terra, associated with the Medusae Fossae Formation, and in the northern lowlands proximal to the north polar cap. In this study, crater fill material refers to an interior mound, generally separated f...
