Rational use of medicines remains to be one of the most challenging problems in health systems worldwide. Kazan Federal University researchers conducted a practical study to assess the impact of introducing evidence-based principles to the practice of medicine procurement in order to manage budget expenditures on medicines of a multidisciplinary health facility for the period of 2011-2014.

Cruise tourists are not influenced by extended shopping opportunities. They spend very little money during the port of call even when they are offered an increased number of spending options.
Bergen is Norway´s largest cruise harbour, hosting more than 300 cruise ships every season. The local tourist industry, media, port authorities and politicians often praise the ever increasing number of cruise arrivals to Bergen, but for no good reason, according to Professor Svein Larsen at the Department of Psychosocial Science at the University of Bergen (UiB).
(Boston) - For salt marshes, hurricanes are just another day at the beach.
These coastal wetlands are in retreat in many locations around the globe--raising deep concerns about damage to the wildlife that the marshes nourish and the loss of their ability to protect against violent storms. The biggest cause of their erosion is waves driven by moderate storms, not occasional major events such as Hurricane Sandy, researchers from Boston University and the United States Geological Survey now have shown.
AMES, IA - As the popularity of fresh culinary herbs increases, growers are looking to year-round production methods to supply distributors and local consumers. In colder climates, culinary herb growers rely on controlled indoor environments and often employ hydroponic production techniques. A new study of basil varieties grown using two popular techniques found that plant performance is more likely related to the choice of cultivar than the type of hydroponic system used.
Using new images that show unprecedented detail, scientists have found that material rotating around a very young protostar probably has dragged in and twisted magnetic fields from the larger area surrounding the star. The discovery, made with the National Science Foundation's Karl G. Jansky Very Large Array (VLA) radio telescope, has important implications for how dusty disks -- the raw material for planet formation -- grow around young stars.
Japan -- Auroras are dimly present throughout the night in polar regions, but sometimes these lights explode in brightness. Now Japanese scientists have unlocked the mystery behind this spectacle, known as auroral breakup.
For years, scientists have contemplated what triggers the formation of auroral substorms and the sudden bursts of brightness. Appearing in the Journal of Geophysical Research, the current study overthrows existing theories about the mechanism behind this phenomenon.
Just under four months into the science phase of the mission, NASA's Magnetospheric Multiscale, or MMS, is delivering promising early results on a process called magnetic reconnection -- a kind of magnetic explosion that's related to everything from the northern lights to solar flares.
Tropical Depression 29W was being battered by vertical wind shear from the day it formed and just two days later it dissipated as it reached the southern Philippines. NASA's Aqua satellite captured temperature data on the storms within the remnant low pressure area after it made landfall.
Tropical Depression 29W, known locally in the Philippines as "Onyok" made landfall over Caraga / Manay, Davao Oriental, according to PAGASA and has weakened into a low pressure area.
The JRC has been looking into the risks of space weather impact on critical infrastructures. A new report explores the rail sector's vulnerability and the potential impacts, in particular through interdependencies with other infrastructures. Awareness among operators and regulators worldwide is currently limited and vulnerabilities across the rail sector need to be identified, authors say.
For the first time, researchers have successfully dated the carbon dioxide (CO2) and methane (CH4) emitted by ponds and lakes on Bylot Island, Nunavut. The research team observed significant variability in age and emission rates of greenhouse gases (GHG) from aquatic systems located in a continuous permafrost zone. The study, whose lead author is Frédéric Bouchard affiliated to the INRS Eau Terre Environnement Research Centre and the Geography Department of Université de Montréal, appeared in the international journal Biogeosciences.
Black holes at the heart of galaxies could swell to 50 billion times the mass of the sun before losing the discs of gas they rely on to sustain themselves, according to research at the University of Leicester.
In a study titled 'How Big Can a Black Hole Grow?', Professor Andrew King from the University of Leicester's Department of Physics and Astronomy explores supermassive black holes at the centre of galaxies, around which are regions of space where gas settles into an orbiting disc.
Borrowing insights from techniques used to image cancer, Stanford scientists have devised a new method for generating "training images" that can be used to fine-tune models of uncertainty about underground physical processes and structures.
Having an accurate picture of the planet's subsurface is crucial for rational decision-making across a wide variety of activities, including environmental cleanup, oil and natural gas well-drilling, and the underground sequestration of greenhouse gases that contribute to climate change.
It took 100 million years for oxygen levels in the oceans and atmosphere to increase to the level that allowed the explosion of animal life on Earth about 600 million years ago, according to a UCL-led study funded by the Natural Environment Research Council.
DURHAM, N.C. -- Accelerating rates of sea-level rise linked to climate change pose a major threat to coastal marshes and the vital carbon capturing they perform. But a new Duke University study finds marshes may be more resilient than previously believed.
The research, published this month in the Proceedings of the National Academy of Sciences, shows that the significant boost in marsh plant productivity associated with elevated levels of atmospheric carbon dioxide will allow marshes to trap more sediment and create more organic soil.
Their analysis revealed that the periods of Algol (2.85 days) and the Moon (29.6 days) strongly regulate the actions of deities in this calendar.
- Until now, there were only conjectures that many of the mythological texts of the Cairo Calendar describe astronomical phenomena. We can now unambiguously ascertain that throughout the whole year the actions of many deities in the Cairo Calendar are connected to the regular changes of Algol and the Moon, says Master of Science Sebastian Porceddu.
