The ionospheric sounding data at two southern hemisphere stations, the Argentine Islands and Port Stanley, are analyzed using a method previously developed by the authors. Negative trends of the critical frequency foF2 are found for both stations. The magnitudes of the trends are close to those at the corresponding (close geomagnetic latitude) stations of the northern hemisphere, as considered ...

Migration is a common behavior used by animals of many taxa to occupy different habitats during different periods. Migrant birds are categorized as either facultative (i.e., those that are forced to migrate by some proximal cue, often weather) or obligate (i.e., those that migrate on a regular cycle). During migration, obligate migrants can curtail or delay flights in response to inclement weat...

PCB signatures can be used for source identification, exposure studies, age dating and bio-monitoring. This study uses comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCxGC-ToFMS) to produce a PCB signature comprised of over 80 PCBs for individual Leach's storm petrels (Oceanodroma leucorhoa). The Leach's storm petrel is a relatively small, elusive, under...

Specification of realistic environmental design conditions for marine structures is of fundamental importance to their reliability over time. Design conditions for extreme waves and storm severities are typically estimated by extreme value analysis of time series of measured or hindcast significant wave height, HS. This analysis is complicated by two effects. Firstly, HS exhibits temporal depen...

We studied 1035 consecutive postinfarction patients to determine the feasibility of altering type A behavior and the effect such alteration might have on subsequent rates of infarction and cardiovascular death. Approximately 300 subjects were enrolled in small groups and primarily received cardiologic counseling on the usually accepted coronary risk factors. Six hundred subjects received, in ad...

Coronal Mass Ejections (CMEs) are large, energetic expulsions of mass and magnetic fields from the Sun; they can significantly affect large volumes of the heliosphere and appear to be a key cause of geomagnetic storms. The present study deals with the influence of Asymmetric 'Full' Halo CMEs, Partial Halo CMEs, Asymmetric and Complex 'Full' Halo CMEs and 'Full' Halo CMEs on cosmic ray intensity...

The perfect storm is brewing. The proportion of the world’s population age 60 and older is projected to grow from 11% to 22% between the years 2000 and 2050, an absolute increase from 605 million to 2 billion people [1]. Health systems across the globe are ill prepared to meet the needs of aging populations. The challenges are many. Underinvestment in prevention contributes to the rising burden...

In order to meet ever-increasing customer service expectations, electric utilities must continuously improve the reliability of their electric distribution systems. Over the last decade, utilities have invested in digital technologies that give them near-real time readings on the health of their electric grid. This data is incredibly useful during major storm outages, but the flood of data pour...

Today at a time of global economic and financial crisis, timber industry in Slovakia, as well as other industry, is not just trying to look inside for company reserves in production processes, but also identifies new trends in production and its competitiveness in world markets. It is obvious that the pulp and paper industry needs to keep up the competitive pressure with new trends in efficient...
