Researchers at the Group Health Research Bromatological (HIBRO), Faculty of Veterinary Medicine, University of Cordoba (UCO) and the Agrarian Technological Institute of Castile Leon (ITACL) in Spain, have developed a new method to characterize how to distribute pathogens Listeria monocytogenes and Salmonella in fresh pork. These microorganisms, which are characterized by their ability to survive at low temperatures, may compromise the health of consumers when they are in high concentrations. To reach these conclusions, the researchers analyzed how they affect the concentration levels of these pathogens changes in storage temperature suffering from these meat products that are purchased at the point of sale until they reach households.
In an article published in the International Journal of food, microbiology the research team has shown that the application of mathematical techniques based on probabilistic calculations is effective in identifying how pathogens are distributed in fresh produce from pork. “Refrigerated storage gets inhibit the growth of microorganisms, but some of them are able to remain at low temperatures. This mathematical method has allowed determining the concentration of both pathogens in contaminated lots and thereby improving control of the raw material and processing operations, thereby minimizing the risks associated with fresh meat, “explains researcher UCO Antonio Valera.
Researchers from the Andalusian Centre for Developmental Biology (CABD), Joint Research Center of CSIC, the Pablo de Olavide University of Seville and the Andalusian in Spain, recently published an article in the journal Biogerontology in presenting the results of the work done in the nematode Caenorhabditis elegant, which states that although there is a correlation between the deterioration of the core structure and age of the individual, does not always happen this way, indicating that the deterioration of the core structure not necessarily the cause of aging, a widely accepted hypothesis among many scientists.
Understanding why and how organism’s age has been and remains one of the great challenges in biology and biomedicine. As we age our body’s many functions are altered and deteriorate, increasing the risk of diseases like diabetes, cancer or Alzheimer’s. Molecular mechanisms proposed to explain this process have been varied, including the accumulation of oxidative stress damage in various cell components, a decrease in the ability of our DNA repair or mitochondrial dysfunction that control cellular metabolism. Not much was found that a mutation in the LMNA gene, which is part of the nuclear membrane, causes a rare disease called progeria ago.
An analysis of data reveals the possible detection of an exomoon (a satellite orbiting a planet outside our solar system). The received signals are not yet clear enough to rule that detected the footprint of an interaction between a star and a planet close to her. The discovery was made by observing a fortuitous meeting (from the visual perspective of the Earth) between cosmic objects in our galaxy, which can only be provided once. Due to the unique nature of the event, will be very difficult to solve the enigma, as there will be another opportunity to observe the candidate exomoon from Earth in viewing conditions as favorable as those enjoyed on this occasion will.
Nevertheless, it is likely that more cases like this, fleeting detections moons orbiting planets outside our solar system are given. Research on which has made possible detection of this exomoon the work of a team of scientists from institutions in Japan, New Zealand and the United States, including, among others, David Bennett of the University Of Notre Dame in Indiana, United States, and has been funded by NASA. The observations were made mostly using telescopes in New Zealand and Tasmania. The technique, based on the effect of gravitational microlensing, fail casual alignments between stars.
The operation of the interior of the Earth remains a mystery to geologists and physicists. One theory-to be confirmed although quite accepted, argues that the movement of tectonic plates is due to subduction, ie, the sinking of one plate under the other by differences in density. however, recent work led by Ana Maria Mancho, CSIC researcher and also a member of Jezebel ICMAT Curbelo, in Spain, shows examples of fluid convection indicate that the movement could occur spontaneously, the result only of the internal dynamics of the fluid and in the presence of symmetry.
The results suggest that the symmetry of the terrestrial sphere could be important for the formation of plaques in motion. “In our article we see that the spontaneous movement is a global solution of the system in which tremendously influences the symmetry, although in our study the symmetry is simpler than on Earth, “he said scientific. In an article published in the journal Physics of Fluids, the authors propose a model of the lithosphere on mantle convection, from analyzing the instabilities of the fluid. In these equations have found some solutions, related to the presence of symmetry, corresponding to spontaneous and fleeting movements of the plates. “Mantle to geological time scales is a fluid with properties that sometimes cannot be measured directly.
A new mid-range model or input reaches the Spanish market with an attractive price. We refer to Wiko Rainbow, a model that costs only 159 euros in its free version and we have as a striking feature, which goes on sale in case of different colors: black, white, blue, coral, fuchsia and yellow. As a good model of the segment that is positioned quality panel that comes into play is 720p, for a size of five inches. By the way, is the IPS panel type, so a good quality is more or less assured? Regarding the dimensions of this model, these are the ones that have: 148 x 74 x 9.3 mm, which is not bad (in terms of weight, these amounts to 167 grams).
As for the fundamental components of this Wiko Rainbow, I must say that not stand out against other models on the market, but not clash. The processor is four cores running at a frequency of 1.3 GHz (it looks like it is from MediaTek and architecture Cortex-A7) and RAM is 1 GB. I mean, you need to avoid problems in day to day, but clearly cannot compete with more powerful (and expensive) devices. Other features to consider of this Wiko Rainbow to estimate its possible purchase are as follows (all of which reaffirm that belongs to the mid-range or entry):
Few such important advances as it could bring graphene have been carried out in the history of technology. The use of graphene not only would be a slight increase in what we now know, it would completely change the basis on which we have worked for so many years. Silicon, the material that gives its name to Silicon Valley, could become part of the past, all because of Samsung. The benefits of graphene as a material of construction are many. It is a material with a high resistance, is a material with high conductivity, and is a material that is very flexible.
It has everything you need to advance in the world of technology, except for one thing, so far was not easy or cheap to produce. We say so far because we have Samsung found a way to produce graphene on a large scale. In addition, although it is likely that this system is still more expensive to produce silicon would forever change the world of technology. The new graphene synthesis system was developed in collaboration Sungkyunkwan University. Samsung’s goal, as announced, is mass-producing graphene and market sooner.
Much talk of this material as a panacea for consumer electronics and unable to see anything commercial … for now. In addition, who could have taken the lead when it comes to think of a marketing graphene? As the giant Samsung. The Koreans, through its Division Samsung Advanced Institute of Technology (SAIT) in collaboration with the Sungkyunkwan University, have succeeded in developing a system for the first time to achieve commercially viable synthesis of graphene.
The manufacture of this material qualities of lightness, flexibility, strength and conductivity unseen before in the world of electronics and the every day you discover something new but we could not see what he can in reality still presents the difficulty that large scale, part of the material lost its privileged qualities. When synthesized from the union of small crystals also conductivity, for electronics, declined. In addition, I had to do so the costs to levels that prevent their actual marketing.
