We have used total electron content (TEC) values from low, middle, and high latitudes recorded over the American continent and density and ion temperature measured in situ by the DMSP-F15 and F17 satellites during the geomagnetic storms of 3-4 August 2010 and 5-6 August 2011 to study the formation and dynamics of plasma density enhancements that developed during these two storms. Common to both storms are the timing of the main phase that extends between 20 and 24UT and their seasonality with both storms occurring near the end of the Northern Hemisphere summer solstice. During both storms, TEC data show incipient equatorial anomalies lacking a poleward expansion beyond 20° magnetic latitude. Two large-scale TEC enhancements were observed at middle latitudes showing a complicated pattern of structuring and merging. The first TEC enhancement corresponds to a storm-enhanced density (SED) seen between 21 and 01UT on the following day. The second TEC enhancement was observed over Central America, located equatorward of the SED and apparently moving northward. However, careful analysis of the TEC values indicates that this second TEC enhancement is not transported from lower latitudes through a superfountain effect. Instead, the enhanced plasma has a local origin and is driven by a southward directed meridional wind that moves plasma up the tilted magnetic field lines. DMSP flights passing over the second TEC enhancement show a reduction of the ion temperature, confirming an adiabatic expansion of the plasma as it moves up the field lines. It is concluded that the midlatitude TEC enhancements do not arise from a low-latitude ionospheric fountain effect. © 2017. American Geophysical Union. All Rights Reserved.

Vaccine | Year: 2010
Antibody to the neuraminidase (NA) antigen of influenza viruses has been shown to correlate with immunity to influenza in humans and animal models. In a previous report, we showed that an inactivated influenza vaccine containing 60 μg of the hemagglutinin (HA) of each strain induced significantly more serum anti-HA antibody among elderly persons than did the standard vaccine containing 15 μg of the HA of each component. We developed a lectin-based assay for anti-NA antibody and used it to measure anti-NA antibody responses among subjects who had participated in that study. The high dosage vaccine contained eight times as much NA activity as the standard vaccine and induced a significantly higher frequency of antibody responses and higher mean postvaccination anti-NA titers to the N1 and N2 of the A/H1N1 and A/H3N2 viruses in the vaccines than did the standard vaccine. Ensuring an increased antibody response to the NA antigen in inactivated influenza virus vaccines should increase the protection against influenza. An increased quantity of the NA antigen in the vaccine will ensure an increased response. © 2009 Elsevier Ltd.

This study has used total electron content (TEC) values from an extended network of GPS receivers and a highly developed processing to characterize the conjugacy of medium-scale traveling ionospheric disturbances (MSTIDs) over the American continent. It was found that midlatitude nighttime MSTIDs, also named electrobuoyancy waves, map into the opposite hemisphere but the amplitude of the TEC disturbance in the Southern Hemisphere is between 8 and 13% of the amplitude in the original hemisphere. The periods of the MSTIDs vary between 50 and 65min. MSTID dynamics is presented for two days: 20 August 2012 and 17 June 2012. On the first day, MSTIDs entered into the American sector shortly before 4 UT, last for 3h, drifted at an average speed of 200m/s, and dissipated in the Caribbean region. In the Northern Hemisphere, the MSTIDs were directed southwestward (SW) and 60° from south. In the Southern Hemisphere, they moved northwestward (NW) or ~60° from north. The MSTID velocity changed through the night from ~300m/s to ~150m/s, but the propagation direction did not vary. On 17 June 2012 a series of wide MSTIDs were seen traveling across the Caribbean region that exited through the western coast of Central America. These MSTIDs last for ~5h. Number density measured with the DMSP-F15 and DMSP-F17 satellites confirm the notion that the MSTIDs consist of rising and falling sheets of plasma density driven by electric fields likely set by a Perkins-type instability. These observations support the notion that gravity waves can seed and boost the growth of the nighttime MSTIDs. ©2016. American Geophysical Union.

Little is known about how the reasons that college student drinkers and abstainers have for choosing not to drink might differ. The present study examined this issue among a sample of 2,500 U.S. college students from 18 colleges and universities. Abstainers endorsed significantly more reasons for not drinking than drinkers, and among drinkers, light drinkers endorsed more reasons than heavy drinkers. Abstainers' decision not to drink appeared to be a lifestyle choice that was supported by multiple reasons, including personal values, religious beliefs, not wanting the image of a drinker, and beliefs about alcohol's effect on behavior. Heavy drinkers were more likely to endorse situational reasons such as having to drive home later or being concerned about school work or weight gain from drinking. Implications of these findings for alcohol prevention work on college and university campuses are discussed. © 2010 Springer Science+Business Media, LLC.

Current business environment in world perspective brings different impact on possible development. During economic crisis in last couple of years world economic growth has getting slower, market shares are rapidly falling down. That situation could create new dimension of competition because of large competitors' intensity on the market due to developed logistics and information technologies. Based on the theoretical data there are applied statistical methods, which should be achieved of main aim of the paper. The main aim of the article is defining possible trend of using business tools as a way, how is practicable get out of economic crisis. For this reason there was used questionnaire survey, focused on small and medium companies during economic crisis (between 2009 and 2013). Observed business tools have quite excellent usage not only in the time of crisis, but also in prosperity times, when the companies provide unique competitive advantages. During tracked periods there were advance of gained knowledge about compensation tools by various learning methods. © 2015, Mendel University of Agriculture and Forestry Brno. All rights reserved.

Mitigation of agricultural diffuse pollution poses a significant policy challenge across Europe and particularly in the UK. Existing combined regulatory and voluntary approaches applied in the UK continue to fail to deliver the necessary environmental outcomes for a variety of reasons including failure to achieve high adoption rates. It is therefore logical to identify specific on-farm mitigation measures towards which farmers express positive attitudes for higher future uptake rates. Accordingly, a farmer attitudinal survey was undertaken during phase one of the Demonstration Test Catchment programme in England to understand those measures towards which surveyed farmers are most receptive to increasing implementation in the future. A total of 29 on-farm measures were shortlisted by this baseline farm survey. This shortlist comprised many low cost or cost-neutral measures suggesting that costs continue to represent a principal selection criterion for many farmers. The 29 measures were mapped onto relevant major farm types and input, assuming 95% uptake, to a national scale multi-pollutant modelling framework to predict the technically feasible impact on annual agricultural emissions to water and air, relative to business as usual. Simulated median emission reductions, relative to current practise, for water management catchments across England and Wales, were estimated to be in the order sediment (20%)>ammonia (16%)>total phosphorus (15%) nitrate/methane (11%)>nitrous oxide (7%). The corresponding median annual total cost of the modelled scenario to farmers was 3 ha(-1)yr(-1), with a corresponding range of -84 ha(-1)yr(-1) (i.e. a net saving) to 33 ha(-1)yr(-1). The results suggest that those mitigation measures which surveyed farmers are most inclined to implement in the future would improve the environmental performance of agriculture in England and Wales at minimum to low cost per hectare.

Unlike other steroid hormone receptors, the glucocorticoid receptor (GR) is not considered an oncogene. In breast cancer, the estrogen receptor (ER) drives cell growth, proliferation, and metastasis, and the androgen receptor (AR) plays a similar role in prostate cancer. Accordingly, treatment of these diseases has focused on blocking steroid hormone receptor function. In contrast, glucocorticoids (GCs) work through GR to arrest growth and induce apoptosis in lymphoid tissue. Glucocorticoids are amazingly effective in this role, and have been deployed as the cornerstone of lymphoid cancer treatment for decades. Unfortunately, not all patients respond to GCs and dosage is restricted by immediate and long term side effects. In this chapter we review the treatment protocols that employ glucocorticoids as a curative agent, elaborate on what is known about their mechanism of action in these cancers, and also summarize the palliative uses of glucocorticoids for other cancers. © 2015 Springer Science+Business Media New York.

SOCIETY is failing to meet the obligation it has to its dying members. Persons with terminal illnesses suffer isolation and neglect in hospitals, receive overzealous treatment by physicians, and are kept in ignorance of their situation by families and medical personnel. Evidence for these statements has come from observers of the medical care system and from dying patients themselves (Kbler-Ross, 1969; Reynolds and Kalish, 1974; Sudnow, 1967). In the nineteenth century it was common for persons to die in the familiar environs of their homes, surrounded by grieving families from whom they parted in a meaningful manner (Blauner, 1966). Dying persons of today no longer fill a well-defined social role. Instead, the distinction between the roles of sick and dying persons has been lost and, in the resulting confusion, the care of dying people has suffered. The purpose of this article is to clarify the distinction between the dying and sick roles, identify the signs of existing role confusion, suggest ways in which this confusion may be corrected, and show how reestablishment of the dying role can result in improved care of dying people. The important part physicians play in defining sick and dying roles will be emphasized.
