Doğu Anadolu Gözlemevi (DAG) projesi 2011 yılında Erzurum’da başlatılmıştır. DAG’da 2021 yılı sonunda ilk ışığın alınmasıyla Türkiye'nin en büyük (4 m) optik ve kızılötesi teleskobunun kurulum sürecini tamamlaması planlanmaktadır. Yer tabanlı astronomik gözlemevleri için bulutluluk hayati atmosferik parametredir. Bulutluluk oranı, bulut türleri değişimi yer bir gözlemevinde gözlemlerin yapılmas...

OBJECTIVES To compare the relative axis modification and canal concentricity after glide path preparation with 20/0.02 hand K-file (NITIFLEX®) and 20/0.04 rotary file (HyFlex™ CM) with subsequent instrumentation with 1.5 mm self-adjusting file (SAF). MATERIALS AND METHODS One hundred and twenty ISO 15, 0.02 taper, Endo Training Blocks (Dentsply Maillefer, Ballaigues, Switzerland) were acquire...

A satellite-based climate record of monthly mean surface solar irradiance (SIS) is investigated with regard to possible inhomogeneities in time. The data record is provided by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) Satellite Application Facility on Climate Monitoring (CM SAF) for the period of 1983 to 2005, covering a disk area between ±70◦ in lat...

Appropriate information on solar resources is very important for a variety of technological areas, such as: agriculture, meteorology, forestry engineering, water resources and in particular in the designing, sizing and monitoring of solar energy systems. Solar radiation is observed by means of networks of meteorological stations. However, the availability of observed solar radiation measurement...
