These products and the diverse uses given to them in a house environment entail a dangerousness which is not always taken into account in an adequate way. Teachers train other teachers and health agents about how to manipulate them and the correct use to avoid intoxications.
In economy, the standard view conceives language as empty words. However, there are speakers who are not willing to distort information. Besides, language is a social convention: if it is not used in its usual sense it can result impossible for the listener to decode it. Natural language provides a simple mechanism by which there can be generated consistent expectations between the participants of strategic interactions.
Researchers are analyzing sheep’s capacity to self-medicate. The animal behavior evidences that when they feel digestive discomfort caused by parasites, they select plants which contain tannins, which are beneficial for the health. Between the objectives of this research there are to obtain management guidelines to mix this kind of plants in the environment in order to optimize the productivity and animal welfare.
The unexpected and destructive in Japan was not the earthquake, but the tsunami. There existed a prediction of the scientists about an average recurrence of earthquakes every one thousand years. That is what the Geologist Carlos Costa remarks. He is a member of the Global Earthquake Model (GEM), and in an interview to InfoUniversidades talks about the disconnection between scientific information and politic decisions, the continuity of the aftershocks and the geologic theory of the “seismic gap”.
The difficult and traumatic process of learning Mathematics to which numerous generations were submitted is the origin of the natural divorce between discipline and daily life. It is looked at with respect, but sideways. In this interview with InfoUniversidades, the Dr. in Mathematics Juan Eduardo Nápoles Valdés demystifies the historical darkness of science and talks about the challenges for teaching it in the next years.
A team of scholarship holders and researchers carries out tests in vivo and in vitro of photosensitizing agents and their application in photodynamic therapy to treat colon and skin cancer. The tests point to the capacity of certain agents to cause the death of malign cells in combination with light, at the same time as they analyze the mechanisms of resistance which the cells develop against this kind of therapy.
An analysis of country people’s reality in Argentina reveals the invisibility of its diversity. The evaluation to which family agricultural groups are submitted oscillates, in general between the mythic thought and its consideration as a residual category facing the modern and urban. The analysis proposal lies in that the regional development must contemplate a new perspective about the different production styles.
In a culture where there dominate the images and the advance of technology is unavoidable the problem in relation to the people with visual disabilities does not lie in the disability, but in the awareness on the part of the society about accessibility. This is what teachers and researchers state and dictate a Braille course in which they deal with the accessibility and spread of tiflotechnology as the way for social integration.
Departing from the research project “Urban Contamination with dog’s stool”, there were developed tests to turn domestic animals stool into biogas. The use of a biodigestor permitted the specialists to carry out the trials which produced a considerable amount of the combustible. The results generate the possibility of expanding the tests, as the resource is abundant, free and besides, it reduces the contamination caused by the waste.
A recent research shows that the coasts of Comodoro Rivadavia present different levels of contamination by industrial and domestic waste. So is much so that one of the pathogenic agents responsible for the sewage microbial pollution in the sea is the sewage coliform bacterium (Escherichia coli), used as evidence of sewage contamination.
Since three years ago, scientists have been studying the preventive effects which the anti-inflammatory and antioxidant agents present in extra virgin olive oil can have on certain brain proteins. These proteins are affected by oxidative stress, one of the causes of Alzheimer, and intervene in cognitive functions such as memory and language. The results obtained at laboratory scale confirm the researchers’ hypothesis.
A group of researchers from AIGroup defined an alternative way so that machines “understand” the natural language. Differently from the usual techniques, this is based in morphosyntactic principles and doesn’t take into account semantics. The new method functions through mechanisms which could be compared to those used by the human brain in the speaking process.
Researchers simulated the conditions of harvest, packaging and transport to Europe to know the levels of pesticides present in tangerines Okitsu. To avoid post harvest diseases the producers use fungicides, such as carbendazim. The researchers proved that the fruits contained chemical residues below the maximum permitted.
Researchers from Mendoza analyzed data about collection, treatment and deposits of electronic trash generated by companies, institutions and users in general. This waste puts into risk the human health and the environment, given that it contains toxic substances which filter in the groundwater causing a high level of contamination. The researchers plan to elaborate a diagnosis and project the evolution of this waste and its management to avoid environmental impact.
A group of engineers, through the application of technologies for social development patented solar equipment to purify the water aimed at rural populations’ houses from the north of Argentina. The isolation situation requires a device which doesn’t need materials or maintenance and which, in case of needing it, it is simple to use for any person.
Based on an important statistic database with thermal and rain registers of up to 100 years ago the Professor María Emilia Pérez hold in an interview to InfoUniversidades that “there are not enough elements to talk about climate change in strict sense; but we could say that we are facing variations, fluctuations or climate oscillations which are within the normal parameters”.
Scientists from the Center for Applied Zoology research the migration of these birds in Argentinean territory, using a technology of satellite following. The specie suffers by the transformation in the rice fields of the natural marshlands, where they usually rest and eat. The project points to generating useful information to develop policies for conservation and sustainable use of the ducks’ fauna in the country and in neighboring countries.
Through a new methodology, for which it was used an automatic smoker designed in the laboratories of the University of San Luis, researchers analyzed the presence of nickel in diverse cigarettes’ brands. In high concentrations, this metal present in the cigarettes’ smoke can cause from rhinitis to lung cancer and affects active as well as passive smokers.
Dr. Roberto Yunes analyzes an article published in “PLoS Medicine” and states the credibility of the Random Clinical tests and the use of drugs for different diseases, with the only objective of achieving their profitability. There wouldn’t be diseases to treat, but drugs to which we would have to look for potential pathologies to be useful with the only purpose, many times, of increasing their sale.
Many fragrances used in cosmetic products are originated in chemical plants. Far from flowers and prairies, the industry synthesizes chemical compounds to elaborate perfumes and flavors. A team of scientists tried different alternatives to obtain the substances used in the production of fragrances with the same performance as the current technology, but reducing environmental pollution.
Teachers and students from different careers of the UNCuyo carry out a project together with social and state organizations which permit many families from rural areas to make their own houses from traditional knowledge incorporated to bioconstruction methods with thatch. To take care of the environment is priority, as well as anti-seismic methods in a line which combines tradition, identity and technical innovations.
Scientists from Bahía Blanca and the Conicet work on the development of biotechnological tools aimed at improving wheat’s value chain. Technologies based on DNA, like transgenesis and molecular markers are combined with others, such as phytopathology to obtain highly competitive wheat worldwide. The project is already part of the International Committee for Wheat Genome Sequencing.
Teachers and researchers of the UNLaR elaborate new agro-industrial products in the Technological Park. This time, it is a handmade beer flavored with white carob flour. The new drink called “Solar”, elaborated without preservatives and with a slightly superior alcoholic content keeps autochthonous characteristics and generates new productive enterprises. There will also be a honey flavored variety.
In the region of the Patagonic Andean Woods there live small bats which nest in trunks of trees or in antique and damaged buildings. These mammals fulfill their role in the ecosystem eating insects and avoiding them to become plagues. The biologist Analía Giménez could identify five species of flying mammals.
In the province of Jujuy, researchers found fossil samples of terrestrial plants belonging to the Inferior Ordovician Period. The data indicated that they are approximately 470 million years old, which turns them into the most antique register of terrestrial plants known up to the present. The work constitutes a significant contribution to the reconstruction of the history of evolution, given that it is about the terrestrial colonization on the part of living organisms.
An interdisciplinary team of the School of Agriculture could produce alternative energies with agricultural, agro-industrial and organic waste origin raw material, which do not imply the use of potentially consumable elements, such as grains or corn or soy oils. From used oils it was produced biodiesel, whereas with different origin waste there were generated combustibles such as bioethanol or biogas.
The National University of La Plata participates in an international research project in which new iron compounds are synthesized to fight against tuberculosis. The disease, caused by various species of the same bacterium mainly affects developing countries and it is currently considered a re-emergent illness. The iron compounds developed could be used in the future as therapeutic agents and hospital disinfectants.
