And when I looked at the data about the number of blood units collected year over year, it has shown dramatic increase, but even today I was informed that there is urgency in getting blood to the hospital because it’s affecting patient care if they do not get blood donors in the door.”Linda Barnes is from the Pan American Health Organization, and not only was she here for a two day workshop aimed at strengthening our blood bank system; but she was here to help us to draft a national policy; something PAHO is requiring all countries to do. “So we talked a lot about strategies, we actually completed a draft policy on universal access to safe blood, so we will be positioning Turks and Caicos to respond to PAHO’s request that we put a blood policy in place, and we also talked about real down to earth strategies, good ideas, what I’ve seen in the different countries that I’ve worked in ranging from central Asia to sub-Saharan Africa and now the Caribbean.”A regular pattern of blood donation is key and Barnes said the mix of public and private practitioners were exceptional and motivated to see the policy established in law and to find ways to engage more community groups so that the Blood Bank is never broke of having safe and universal access to blood.
The government on Thursday said prices of pulses were easing as per reports from states due to de-hoarding operations and arrival of fresh crop, but a look at the retail rates reveal that this daily source of protein continues to remain dear.”Retail prices of pulses have registered declining trends as per market reports from the states. Release of pulses seized under de-hoarding operations is being expedited,” the ministry of consumer affairs, food and public distribution said in a statement.”Arrival of new crop has also started. This will help to moderate prices further,” it said, adding that Tur or Arhar dal was cheaper by as much as 3.59 percent in the past week alone at Rs.152.11 per kg on November 18, against Rs.157.77 before that.Similarly, it said the price of Urad dal was down by 6.08 percent — from Rs.150.43 a week ago to Rs.141.28 on Wednesday.But at the retail level, the government’s claims did not appear to hold ground.At the Big Basket online retail store, Tur dal was quoting way above at Rs.201 per kg and Rs.375 for a two-kg bag.Reliance Fresh also priced its Tur dal at a price of Rs.219 per kg.At other retail stores, prices fluctuated anywhere between Rs.190 and Rs.230 per kg.Even the commerce ministry data on wholesale price index for October, released on Monday showed that the pulses remained dearer by 52.98 percent over the past year.Even when compared with the previous month, there was a spike of 9.17 percent.The build-up during the current fiscal year, that is since April 2015, has also been rather steep at 41.45 percent.Similarly, data on consumer price index released by the ministry of statistics and programme implementation showed a 22.24 percent inflation rate of pulses as on July 2015, compared to the previous year.The consumer affairs ministry also said thousands of tonnes of pulses had been seized under the de-hoarding operations by the states, which were auctioned or offloaded in the market to increase availability.Curiously, while data released on November 12 said 1,33,828.31 tonnes had been seized, that released six days later showed a lower quantity of 1,32,777.14 tonnes had been confiscated.At the same time, the prices of some other items of mass consumption — onions and tomatoes — were rocketing.On Wednesday, Cabinet Secretary P.K. Sinha reviewed the prices and availability of essential commodities, especially pulses, tomatoes, onions and edible oils in an inter-ministerial meeting.”It was observed that the increase in prices of tomatoes and onions is largely on account of disruption of supplies due to heavy rains in the southern states which is expected to be temporary,” a press note issued after the review said.”The situation is expected to ease in the coming days,” the statement added.
Of course, the model is based on theory, which suggests, Goodman notes, that it could be either right or wrong, and we aren’t likely to know which it is until we send a probe to Europa to study its surface first-hand.

Wicht with the image of Europa taken from NASA/JPL/University of Arizona The NASA space probe Voyager flew past Jupiter and its moons in 1979, and in so doing, set off a debate about the nature of the surface of one such moon, Europa, that has continued to this day—why is the surface so smooth, and why are there odd rough patches covering nearly 40 percent of its surface? Scientists agree that the general smoothness is likely due to the existence of water beneath the icy surface—the lack of craters indicates a surface that is able to heal itself after impacts. Less of a consensus has been found regarding the rough patches, however, which scientists call “chaotic terrain.” In this new study, the researchers used data from hydro-systems here on Earth as well as data from both Voyager and the Galileo spacecraft (which detected a magnetic field) to create what they believe is a reasonable model of a convection process working beneath the icy shell of Europa’s surface.Some have suggested Europa’s surface gets its unique features due to the pull of gravity from Jupiter—others have suggested the sun plays a role. Such theories have not held much weight however, as there is little evidence to suggest that either could account for the chaotic terrain. Instead, the modelers suggest, it’s due to convection driven by heat from the interior of the moon itself. Their model shows, they write that currents beneath the ice tend to deliver heat primarily to the equatorial regions of the surface which in turn causes constant heating, melting and refreezing—resulting they say, in the chaotic terrain that we are able to observe.

(Phys.org) —A team of researchers at the University of Texas with assistance from a computer modeler at the Max Planck Institute in Germany has put together a computer model that might just explain the peculiar surface of Jupiter’s moon Europa. In their paper published in the journal Nature Geoscience, the team suggests the odd surface terrain patterns likely come about due to convection. Jason Goodman of Wheaton College offers a perspective on the researchers’ findings in a News & Views piece printed in the same journal.

Soderlund More information: Ocean-driven heating of Europa’s icy shell at low latitudes, Nature Geoscience (2013) DOI: 10.1038/ngeo2021AbstractThe ice shell of Jupiter’s moon Europa is marked by regions of disrupted ice known as chaos terrains that cover up to 40% of the satellite’s surface, most commonly occurring within 40° of the equator1. Concurrence with salt deposits2 implies a coupling between the geologically active ice shell and the underlying liquid water ocean at lower latitudes. Europa’s ocean dynamics have been assumed to adopt a two-dimensional pattern3, 4, 5, 6, 7, 8, which channels the moon’s internal heat to higher latitudes. Here we present a numerical model of thermal convection in a thin, rotating spherical shell where small-scale convection instead adopts a three-dimensional structure and is more vigorous at lower latitudes. Global-scale currents are organized into three zonal jets and two equatorial Hadley-like circulation cells. We find that these convective motions transmit Europa’s internal heat towards the surface most effectively in equatorial regions, where they can directly influence the thermo-compositional state and structure of the ice shell. We suggest that such heterogeneous heating promotes the formation of chaos features through increased melting of the ice shell and subsequent deposition of marine ice at low latitudes. We conclude that Europa’s ocean dynamics can modulate the exchange of heat and materials between the surface and interior and explain the observed distribution of chaos terrains.Press release If we landed on Europa, what would we want to know? Figure shows simulated zonal flows and temperature fields in planetary convection models in a Jovian (Jupiter-like) system (above) and a Europa-like setting (below). The Jovian simulation shows latitudinal bands of convection, visible as distinct stripes, reflecting the controlling influence of the planet’s rotation. The Europa-like simulation shows a more three-dimensional convection pattern associated with dynamic ocean heat circulation, with greater activity near the equator and less circulation near the poles.
