The configuration and timing of the Arabia-Eurasia continental collision, part broader Alpine-Himalayan collisional system, remains controversial. We conducted sandstone petrology, detrital zircon U-Pb-Hf isotopic trace element analysis, Cr-spinel electron microprobe geochemical analysis samples from Paleocene to Miocene peripheral foreland strata in interior Fars, southern Iran. These data wer...
Six minor alluvial chromite placers (Kolkhoznyi Prud, Verkhne-Yaushevo, Sukhoy Izyak, Bazilevo, Novomikhaylovka, Kiryushkino) and one major littoral placer (Sabantuy) were found in sandy sediments of the Kazanian stage Permian System (Late Roadian Wordian Stages) Southern Pre-Urals. It is shown that morphological features chromian spinels are diverse, which not evidence heterogeneity source. Th...
The Kermanshah ophiolite complex is located in outer Zagros ophiolitic belt and consists of both mantle and crustal suites as remnants of southern branch of the Neo-Tethys Ocean in Iran. Chemical composition determinative diagram of minerals indicates that olivine in dunite, harzburgite and lherzolites has forsteritic composition and in wherlitic rocks is chrysolite in composition likewise orth...
OBJECTIVE Observe and report seat belt use among children transported in belt-positioning booster seats. DESIGN We conducted a cross-sectional, observational survey of children transported in motor vehicles between 2006 and 2007. While drivers completed a survey reporting the child's age, weight and gender, and the driver's age, gender, race, income, education, and relationship to the child; ...
chaldoran area in nw of iran has mesozoic oceanic crust basement. the studied rocks of this region can be divided into three groups: ophiolitic gabbros and pillow lavas, ophiolitic volcanoclastics and eocene lava flows. ophiolitic mafic rocks show continental volcanic arc natures and eocene lava flow shows oib-like nature. during the mesozoic,the chaldoran region was situated in the active cont...
Ultramafic massifs are minor but meaningful components of orogens because they record the mantle properties and processes plate generation, subduction, accretion, collision, thus providing key information about crust-mantle interaction evolution orogens. Here, we present an integrated study field observations, whole-rock mineral geochemistry, zircon U-Pb ages, Sm-Nd Re-Os isotopes for serpentin...
In the past decade the applicability of belt-drives has been extended significantly due to their increased reliability. With automotive engines it is now common to join a large number of belt-drives into a single, long belt-drive with several tensioner pulleys. However, these belt-drives can exhibit complex dynamic behaviors; therefore it is very important to predict the dynamics response of su...
OBJECTIVE Many modern cars have seat belt reminders (SBRs) using loud and clear sound and light signals. These systems have developed over the last few years. This study investigates how these modern systems influence the seat belt use in real-life traffic in built-up areas in some European cities. METHODS The data were collected by field observations in major cities in six European countries...
Maine upgraded its seat belt law to primary enforcement on September 20, 2007. Belt observations during the day and night were conducted along with awareness surveys in state licensing offices. Both daytime and nighttime observed belt use increased in the months following implementation of the law (daytime 77-84%; night 69-81%). Although daytime belt use was generally higher, nighttime belt use...
