Investigation of the distribution of basalts, dolerites, and tuffs in the Kanin–Timan–Pechora large igneous province was completed by generalization of data of geological surveys and analysis of the data of deep drilling. The province appears like a nonisometric ellipse and extends northwestward for a distance of nearly 850 km at the width of 250–500 km. Its area is nearly 285 000 km2. The area of the volcanic rocks is about 85 500 km2. The volume of eruptive material alone could be equal to 1000–1200 km3. The age of formation of the traps corresponds to the late period of activity of the process and was less than 7 mln. y. The formation of the province was result of the action of short-lived and low intensity plumes. But it was one of the episodes of the Late Devonian superplume event in the East European platform. The province is separated by an amagmatic area from neighboring magmatic provinces of the same age. The distance between borders of the provinces is 200–400 km. © 2016, Pleiades Publishing, Ltd.

The aim of this study was to outline the seismologically active zones in Syria using the focal mechanisms of the largest events recorded by the Syrian National Seismological Network over the last decade. A dataset of fault-plane solutions was obtained for 49 events with magnitude ≥3.5 using the first P-wave motions. Most of these events had strike-slip mechanisms in agreement with the configuration of the seismogenic belts in Syria. Normal mechanisms were more scarce and were restricted to certain areas, such as the coastal ranges. These data show that despite the relatively small magnitudes of the events studied, they provide a coherent picture of the deformation that has currently been taking place along the active faults. However, some other faults were inactive during the period of this study. © 2010 by the Istituto Nazionale di Geofisica e Vulcanologia. All rights reserved. Source

This comparative study assesses clean coal related policies in China, India, Australia, and USA; and the impact of those, on uptake of clean coal technologies (CCTs) by industry. The study identifies types and examples of CCTs that can be incorporated and applied in reducing coal power related emissions; defines nature and categories of clean coal policies for purposes of exploring policies a particular country is using; and then analyzes the influence of a particular policy to the country's situation. Results indicate that progress on commercial development and deployment of these technologies is very possible in both developing and developed countries and fiscal policies are likely to increase uptake and prospects for uptake by private industry. However, integration of non-fiscal policies with participation of private coal energy industry may also help to achieve remarkable development and uptake. © 2016 American Institute of Chemical Engineers Environ Prog.

Circadian clocks regulate plant growth and development in response to environmental factors. In this function, clocks influence the adaptation of species to changes in location or climate. Circadian-clock genes have been subject of intense study in models such as Arabidopsis thaliana but the results may not necessarily reflect clock functions in species with polyploid genomes, such as Brassica species, that include multiple copies of clock-related genes. The triplicate genome of Brassica rapa retains high sequence-level co-linearity with Arabidopsis genomes. In B. rapa we had previously identified five orthologs of the five known Arabidopsis pseudo-response regulator (PRR) genes that are key regulators of the circadian clock in this species. Three of these B. rapa genes, BrPRR1, BrPPR5, and BrPPR7, are present in two copies each in the B. rapa genome, for a total of eight B. rapa PRR (BrPRR) orthologs. We have now determined sequences and expression characteristics of the eight BrPRR genes and mapped their positions in the B. rapa genome. Although both members of each paralogous pair exhibited the same expression pattern, some variation in their gene structures was apparent. The BrPRR genes are tightly linked to several flowering genes. The knowledge about genome location, copy number variation and structural diversity of these B. rapa clock genes will improve our understanding of clock-related functions in this important crop. This will facilitate the development of Brassica crops for optimal growth in new environments and under changing conditions. Source

This paper describes an enhanced monitoring and forecast system for the electrical power generated from wind in Turkey. Wind power plant (WPP) owners, transmission system operator, distribution system operators, and renewable energy experts are the shareholders of this system. The developed monitoring and forecast system is composed of wind electricity analyzers and reference wind masts, one for each WPP, a Wind-Electric Power Monitoring and Forecast Center (WPMFC) equipped with database, data processing, and application servers, and the associated monitoring and forecast software. All shareholders can communicate with the developed WPMFC in order to retrieve preprocessed wind-electric power forecast data and power quality data, through the IP network according to their authorization level. The electrical and meteorological raw data can also be retrieved for postprocessing. The developed system is based on global positioning system (GPS) synchronized, real-time field measurements taken from each WPP, in addition to the use of mesoscale numerical weather prediction models. Instantaneous electrical and meteorological quantities of each WPP can be monitored continuously through the WPMFC. The forecast system employs physical, statistical, and hybrid models combining both approaches. Some sample monitoring and forecast results are given in the paper to illustrate the benefits and abilities of the developed system. © 2012 IEEE. Source
