We report a novel approach for achieving high dielectric response over a wide temperature range. In this approach, multilayer ceramic heterostructures with constituent compositions having strategically tuned Curie points (T(C)) were designed and integrated with varying electrical connectivity. Interestingly, these multilayer structures exhibited different dielectric behavior in series and paral...
• P contents of strongly peraluminous granites (SPGs) from 0-3500 Ma are compiled. Maximum SPGs increase after 720 Ma. concentrations in reflect temporal variability sedimentary abundances. Enhanced recycling into magmas occurs Neoproterozoic. Variable granite influences interpretation detrital zircon chemistry. Phosphorus plays an important role both surface biological cycles as a critical mac...
The Marivan granitoid body of the northern Sanandaj–Sirjan Zone (N-SaSZ) northwest Iran was emplaced into Cretaceous sediments, and is associated with minor amounts iron skarn-type mineralization along contact between intrusion surrounding country rocks. granitoids within include (hornblende-rich) diorite, granodiorite, granite phases, zircon U–Pb dating four samples from this indicate they wer...
the ability of boards to perform their roles depends largely on their composition. board composition refers to the number of directors and type of members as determined by the usual insider or outsider classification. several empirical studies in other country have concluded that board composition determines a board’s power as an instrument of corporate control and contributes to company perfor...
Yamusi granodiorite in the eastern part of Qilian Orogen consists mainly gneissic granodiorite. Researchers have studied other nearby rock masses, and many studies, such as those focusing on zircon U-Pb age chronology geochemistry granodiorite, still need to be completed. We obtained a new LA–ICP–MS 480.3 ± 1.3 Ma for which suggested that it was formed during early Ordovician period. The whole-...
Abstract Granite rocks are currently one of the foremost raw materials that can be used for various economic purposes such as ornamentation and building materials, because they do not possess radioactive concentrations have good physical mechanical properties. The granite north Um Taghir connected to neoproterozoic integrated Arabian-Nubian Shield (ANS), which lies in Northeast Africa. Inductiv...
conclusions the present study has demonstrated that a combination of exercise and silymarin can improve body composition and adiponectin levels. background silymarin has powerful antioxidant properties, but its effects on athletic performance are poorly understood. objectives the present study was undertaken to evaluate the effects of 4 weeks of endurance or strength exercise, with or without s...
a two year field experiment was carried out to evaluate the effects of municipal waste compost (c), composted cattle manure (m), and nitrogen (n) on growth and composition of weeds in a corn field in shiraz using a split-split plot design with 3 replicates. visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...
background in the past 10 years, 13 fatal earthquakes have occurred in iran and led to death of 30,000 people whom most of them were killed in the earlier hours of the disaster. disaster medical assistance teams are groups of trained medical and non-medical personnel with various combinations that on the optimal conditions are deployed just within 8 hours of notification and are able to work se...
forty eight 8-month-old male goats were divided into three groups. in each group, eight goats were feedrestricted for 45, 60 or 75 days, and eight goats served as the control. restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. at the end of restriction period, the restricted goats were offered the same ration ...
