Ionospheric response to the 2009 sudden stratospheric warming over the equatorial, low, and middle latitudes in the South American sector

The present study investigates the ionospheric total electron content (TEC) and F-layer response in the Southern Hemisphere equatorial, low, and middle latitudes due to major sudden stratospheric warming (SSW) event, which took place during January-February 2009 in the Northern Hemisphere. In this study, using 17 ground-based dual frequency GPS stations and two ionosonde stations spanning latitudes from 2.8°N to 53.8°S, longitudes from 36.7°W to 67.8°W over the South American sector, it is observed that the ionosphere was significantly disturbed by the SSW event from the equator to the midlatitudes. During day of year 26 and 27 at 14:00 UT, the TEC was two times larger than that observed during average quiet days. The vertical TEC at all 17 GPS and two ionosonde stations shows significant deviations lasting for several days after the SSW temperature peak. Using one GPS station located at Rio Grande (53.8°S, 67.8°W, midlatitude South America sector), it is reported for the first time that the midlatitude in the Southern Hemisphere was disturbed by the SSW event in the Northern Hemisphere.Fil: Fagundes, P.

Geology of the Brixton Deverill - East Knoyle district (Wiltshire), 1:10000 sheets ST83NE (Brixton Deverill) and ST83SE (East Knoyle) : part of 1:50000 sheet 297 (Wincanton)

The Brixton Deverill-East Knoyle d i s t r i c t lies at the western endof Salisbury Plain and encompasses the north-western part of the Vale of Wardour. The central part of the d i s t r i c t forms part of a dissected plateau developed on Upper Chalk (Figure 1); this reaches a maximum height of 238 m south-east of Brixton Deverill. In the north-west, there are prominent escarpments capped by the Lewes Chalk on either side of the Wylye valley. In the south, the Mere Fault and associated monoclinal structure play an important part in shaping the landscape. In the west, the chalk rises steeply on the north side of the fault from the clay vale to the south. Between West Knoyle and East Knoyle, the steeply dipping Upper Greensand and Chalk strata give rise to strongly featured ground. The principal drainage in the northern part of the d i s t r i c t is northwards by the River Wylye, the only permanent river on the chalk outcrop and its tributaries. In the south-central area, drainage is eastwards by a series of valleys that coalesce just west of Hindon and ultimately join the River Nadder at Tisbury. In the south, on the clay vale, drainage is southwestwards by tributaries of the River Lodden, and south-eastwards by tributaries of the River Nadder. The lowest point in the d i s t r i c t , c.96 m OD, lies in the southern tract. Soils developed on the Upper Greensand and most of the Chalk are light and w e l l drained. However, s o i l s on the West Melbury Chalk, together with some on the clay-with-flint deposits and Kimmeridge Clay are much heavier and poorly drained. Agriculture is a mixture of arable and pasture, with the latter dominant on the Kimmeridge Clay Vale. There are few woods, with deciduous woods confined mostly to the clay vale and the relatively newly planted coniferous plantations on the Chalk and Upper Greensand. Agriculture is the only industry in the area

The Shadowed Vale

The setting sun was reddening with its last fiery glow the walls of the great castle at Blois where it stood on a rising slope above the skirts of the town. It tipped the carved and traceried windows of the roof and gleamed vermillion on hilts of swords and pour-points and slashed trunk-hose as officers and men-at-arms bustled to and fro in the yard. But though their faces were long and they bustled nervously, often they stopped in excited knots to whisper and cast curious glances at the windows of the royal suite. For the Dowager Queen lay dying in a heavy-curtained room and in the next, King Henri de Valois gnawed at his nails and waited. And everyone waited the slowness of fate and Henri de Guise went to console his King

Pieces of Iowa’s Past, February 1, 2012

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. February 1, 2012 THIS WEEK: A Different Oath for Senator Vale BACKGROUND: Senator Jacob G. Vale was born July 7, 1821, in York County, Pennsylvania. In 1847, he married Anne Rex, and they moved to Iowa in 1850. Vale farmed in Lee County, and in 1853, he ran on an independent ticket for the legislature but was defeated. He moved to Van Buren County in 1856. In 1861, he was solicited by both parties to become a candidate for the state Senate. He was elected and served as the only independent senator in the 13th General Assembly. Vale also served in the 14th General Assembly in 1872. In 1873, Vale was the Anti-Monopoly candidate for governor of Iowa. Vale died February 17, 1875. His son, B.R. Vale, served in the Iowa Senate from 1888-189

Reducing Vale\u27s Memory Management Overhead Through Static Analysis

Vale is a multi-purpose programming language that focuses on guaranteeing memory safety with minimal effect on performance. To accomplish this, Vale utilizes a memory management system called Hybrid Generational Memory (HGM). HGM uses generational references to track the state of objects in memory, and static analysis to reduce memory management overhead at runtime. This thesis describes the program that performs static analysis on Vale source code during compilation, and analyzes its effect on the performance of Vale programs
