Drifts, trends and periodic variations were calculated from monthly zonally averaged ozone profiles. The ozone profiles were derived from level-1b data of the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) by means of the scientific level-2 processor run by the Karlsruhe Institute of Technology (KIT), Institute for Meteorology and Climate Research (IMK). All trend and drift a...

Abstract. The total ozone data over Europe are available for only few ground-based stations in the pre-satellite era disallowing examination of the spatial trend variability over the whole continent. A need of having gridded ozone data for a trend analysis and input to radiative transfer models stimulated a reconstruction of the daily ozone values since January 1950. Description of the reconstr...

the goal of this research is the determining of planting date and providing agricultural calendar for corn in kermanshah province using climatic elements of temperature and rain fall. so, at first, long term  climatic statistics are collected from 2001 to 2011  and then  considered to temperature and rain fall parameters like  absolute maximum and minimum  in region during growth period, planti...

An evaluation of the influence of sex upon cerebral atherosclerosis was carried out in 5,033 consecutive autopsies studied by a special well-standardized coding technique. A sex difference in frequency of cerebral atherosclerosis appears from the fourth to the sixth decade. During this period the percentage of female cases with no atherosclerosis lags behind the percentage of male cases by a 15...

after passing more than one decade of appearance of digital libraries in iran, they couldn’t meet their real mission, which is responding to audience needs. surely, this problem is affected by potentially and real factors. so this research wants to recognize resistant factors and driving factors by recourse oriented approach, and then to fit them in integrated model.research method which we app...

BACKGROUND Over the last decade, the Short-Term Assessment of Risk and Treatability (START) has provided a strong evidence base to predict a range of problem behaviors. The implementation of START and adaptation of the services to the use of START have so far been sparsely described in the literature. The purpose of this study was to describe the continuation and the interdisciplinarity of risk...

Observations from passive microwave satellite sensors have provided a continuous and consistent record of sea ice extent since late 1978. Earlier records, compiled from ice charts and other sources exist, but are not consistent with the satellite record. Here, a method is presented to adjust a compilation of pre-satellite sources to remove discontinuities between the two periods and create a mo...

there has been a lot of development in the science of implantology since forty years ago when extensive research began on this field of science. the use of dental implantology has also increased in the last decade, which the main reason is the success of it. recently some of our colleagues participate in short time introductory and advanced courses of implant inside or outside the country and b...
