Questions related to Argentina
Hello everyone! I study various ecological aspects of the mosquito species Aedes aegypti in Argentina. One of them is longevity in adult stage. I have a question about the methodology used in some articles about the time allocated to feeding blood to female mosquitoes. Why do some researchers blood feed females daily or once a week or every 15 days? This question is because I read several articles that also study longevity, but the allotted time feeding blood to females is varied. I don't know what determines the timing of feeding females for longevity in the study. Can someone help me with this?
Hello researchgate community!
My name is Giselle Ailin Chichizola, I am from Argentina (South America) and I have a PhD in biology, currently with a postdoctoral scholarship. I am doing a PCA with different seed germination parameters (% germination, mean and onset of germination time) of natine species from two types of environments in Patagonia, Argentina to study their dormancy mechanisms.
I am using R package "factoextra", and I would like to know what happens with the missing values (NA) in the response variables, what does the program do internally to be able to do the PCA, does it average them, disregard them, put some value to them?
If someone could help me to understand what the program does, I would be pleased to receive your answer. It would be very useful for the revision of a paper.
Thank you very much for your time and I look forward to your reply.
This is a methodological discussion on Lithium, which I pose in form of three open questions: 1) Who to trust when it comes to lithium reserves? Usually It is assumed that there are still no International certification processes but rather evaluations by some National Geological Agencies. Considering that we could be talking about a real sensitive issue, is it possible to imagine other reliable sources? 2) How to determine, rigorously, the commercial value of lithium and its evolution over time? Some apps and/or specialized webs calculate the price of lithium carbonate, even in a clic, although it is difficult to determine where there is exactly negotiated. Are there reliable alternatives? 3) How to calculate, prospectively, the strategic value of lithium? I'm afraid that some forward-looking calculations are excessively linear. Considering the uncertain environment,, is itn't possible to think in a some kind of a correction factor? I have some ideas but I would like to hear your qualified voices Thank you very much

I tried to access the registration systems of both countries at Senasa (Argentina) and DAFF (SAfrica) but with no success. I contacted the respective offices through the channels posted and, so far, no return.
Hi everyone! I hope you are well...
I m working on my master thesis on: imported inflation in Argentina during 2003 and 2019.
Since the country intervene the statistics national institute since 2007, is really difficult to find trustable data for the period 2007 - 2012.
Do you know any data base that would be useful? Im interested specially in the CPI overall evolution and its different categories and whole sale industrial goods.
Thanks a lot!!!
I need a human cardiomyocyte cell line to carry out my research project such as AC16, but it is not currently being commercialized (I live in Argentina). If someone was in the same situation and was able to solve it, your recommendations would be of great help to me.
I am trying to purchase this item in Argentina and it seemed unavailable.
Is there other antibody working properly for Western blot/immunohistochemistry techniques?
Thanks in advance for any help to get this antibody or substitute!
When will South America (or specifically Argentina) win a science Nobel Prize?
Another year without a Nobel Prize coming to South America
The last time that a South American scientist was awarded with a Nobel Prize was César Milstein, Physiology or Medicine, 1984. Are the richest countries rich because they inverts a lot in science? or they inverts a lot in science because they are rich?
The list is very short: Argentine 3, Brazil 1, Venezuela 1
“Pensar a largo plazo y actuar de inmediato”
29 al 31 de Marzo de 2021 - Buenos Aires, Argentina
Frente a la pandemia, la comunidad de LCA tiene las herramientas y la oportunidad de mostrar los beneficios ambientales y sociales a largo plazo de las nuevas preferencias de la humanidad y así potenciar el posicionamiento de tecnologías más sustentables: aquellas que permiten actuar de inmediato, sin perder de vista el largo plazo. Quizás lo más importante es que estas tecnologías podrían consolidarse y convertirse en moneda corriente una vez finalizada la emergencia, logrando mejoras sustanciales en términos de sustentabilidad.
CILCA 2021 propone un espacio para abordar estos nuevos desafíos con su tradicional enfoque de ciclo de vida, aceptando la participación presencial y virtual en todas sus instancias. De esta manera, esperamos proporcionar una solución adaptable a la pandemia actual de COVID-19 y la diversidad de circunstancias que pueden afectar a las personas y limitar su participación en el formato tradicional.
Llamado a presentación de resúmenes para exposiciones orales y posters: hasta el 31 de agosto de 2020, por la plataforma EasyChair: https://easychair.org/cfp/CILCA2021.
We are looking for perfection to contain this novel corona virus and of course that is our priority.
Is perfection possible in every case?
You can see that what is happening around the places!
- Echizen Maru fishing vessel left port in Ushuaia, Southern Argentina, 35 days ago.
- Sailors all tested negative and also had a 14 days quarantine before voyage began.
- When they returned having several sailors fell ill, 57 out of 61 are positive for coronavirus.
- Scientists are baffled because ship had no contact with land while it was gone.
They can’t explain how the symptoms appeared. It is a case that escapes all the descriptions that have been published so far, because that long incubation period has not been described yet!!
Please put your views regarding this news. Thanks in advance.
I am looking for an antibody to show the expression of OVGP1 in porcine oviduct cells in culture. Is there one from Sigma and others form ABCAM. But an antibody is too expensive (at least for us, in Argentina), thus, before buying one, I would like to listen to some experiences from researchers who have already used it
I am trying to undertake a DEA-Bootstrap model to estimate the technical efficiency of banks in Argentina. I want to compare the efficiency scores obtained with the intermediation and production approach to verify if some firms do better or worse with a certain approach. What would be the correct method of doing it? Test for differences in distributions? Difference test in the means? Estimate functions of non-parametric densities?
I would very much like to read the full project, if possible. In Argentina we are trying to develop similar ideas. Is this a compltely novel project, or is it a continuation of other "paving-the-way" endeavors? Do you have published papers with preliminary results?
I have been exploring the mean diurnal cycle of different variables of the ERA5 reanalysis in some regions of South America and I always find strange discontinuities or "jumps", as illustrated in the attached pictures. The examples attached are for 15-year region-averaged mean diurnal cycle of 2-meter temperature and precipitation around northeastern Argentina for DJF (hours in UTC in the x-axis and Celsius*10 or mm/day in the y-axis). For temperature you can see an abrupt jump at 10 UTC and other non-smooth transitions at 16 UTC and 22 UTC. For precipitation you can see the same phenomenon at 7 UTC and maybe 20 UTC. I have also found this type of behavior in other regions (even outside of South America) and in other variables such as winds at different levels and wind convergence. The issue in winds is mentioned in the "known issues" of the ERA5 documentation, but nothing about temperature or precipitation. I would not expect this type of behavior in "smooth" variables such as 2 meter temperature and I have never seen something alike in other models or reanalyses.
Estamos trabajando sobre la migración de la especie en el norte de Argentina, especialmente números de aves migrantes hacia el norte
Often, while thinking about the harsh economic situation in countries like Argentina and Brazil, I would say myself, "OMG, what would they have done without soccer!". This study is a good kickoff -- it should be carried out globally by fellow researchers. And, above all, this is a note of hope for the world.
In my country there is growing support for policies against neoliberalism. The "free market" is destroying education and science. The support for the formula Alberto Fernández and Cristina Fernández de Kirchner already has 9600 signatures. The video of the act: https://bit.ly/2YQDXCB. To sign, complete the form here: https://bit.ly/2RMNzs1. I retransmit what I received from the group Science and Technology Argentina (CyTA = https://cienciaytecnicaargentina.wordpress.com/).
What do colleagues in other parts of the world think?
Comparing the recent reforms undertaken in the health sector by the governments of Argentina, on the one hand, and Chile on the other and to evaluate the role played by politics in these choices thru the different implementation of the digital revolution in the last decades.
I'm searching for information (papers, reviews, conference abstracts) about volcanic fumaroles within the Altiplano-Puna Volcanic Complex, at Argentina. I'm looking for ages and composition of the volcanoes showing these fumaroles.
Se trata de Argentina: el valor del peso nacional baja: en lo que va de marzo perdió un 6% de su valor, los precios crecen en promedio a un 3/4 % mensual, y los salarios no llegan a subir en promedio un 35% anual, los pensionados se prevé que incrementen sus haberes aún un poco menos que los asalariados. Los exportadores estacionales retienen su oferta de divisas y las carteras privadas están dolarizadas. En este escenario desde hace 6 meses el Banco Central y la Tesorería Nacional suben las tasas de interés internas de letras a menos de una año a un nivel que toca el 70% anual. La tasa de crecimiento del pbi es nula y la cuenta corriente es negativa en un 5 % del pbi. Es esto sostenible? Claro que no! Sin embargo coo el déficit fiscal operativo es nulo el presidente del país cree que todo irá bien y estaos creciendo.

The meeting of the G20 was held in Argentina, the meeting between the United States and China being the most important at a global level. China being an economy that in recent years has accelerated the gap with the United States. This probable change of world leadership will provoke a series of accommodations in the different countries, as it believes that it will rebound, if this occurs, in the rest of the countries.
I would like to learn about your project. Wold it be possible to read its proposal? Any papers coming from it already?
The reason I ask about countries and scale of land tenancy or ownership involved is because I would like to compare with our agriculture structure in Argentina. where most of maize production corresponds to what we call extensive agriculture or fields crops, implemented in farms in the scale of around two hundred hectares average. I am interested in approaches and methods proposed to apply agroecoloy on big scale plots.
Thanks in advance.
have material from a kind of Carex. In Flora Argentina only C. polysticha is accepted, but I am not sure if it can be C. pseudocyperus. These specimens, although they have the terminal staminate inflorescence, the 2 inferior to this one are Gynaecandrous. In the descriptions of C. polysticha they do not mention this characteristic, but I understand that they do in C. pseudocyperus. Can someone guide me about it? Thank you
I am working with biogeography of southern Paraguay and the info about Paraguay river evolution is relevant for my work. So, if someone could help me, I will be very gratefull! Specially, I have not any info about the Center and South Paraguay river evolution. Brazilian Pantanal and Formosa, Argentina, have information I already get, but nothing about paraguayan sections of actual river course.
In Argentina, biology teachers usually playfully say to their students "do not ask 'what for', ask 'why'!" ("no preguntes para qué, pregunta por qué"). This expression represents a rejection, in the letter but not necessarily in the spirit, of teleology: final causes and functional language. Do English-speaking Professors of biology, use a similar expression?
I'm from Argentina and i'm working whit genetic expression of degenerative joint disease in dogs. So we're trying to isolate RNA from cartilage to further NGS analysis. But till now we haven't get good results. We need some advices about which is the best kit or method to isolate RNA from cartilage tissue. Could you tell me some about it please?
My best regards
I need to work on cardiomyocytes as hosts of parasitic infection. I have been working with HL-1, but culture media is expensive and it takes a long time to arrive after purchase (I live in Argentina). Therefore, I am thinking of working with H9C2 or AC16. I will need to do siRNA on the cell line I choose. I can easily get H9C2 from another group, but I am a little bit worried about the differentiation/undifferentiation and unfortunately I don´t have anybody that can teach me to culture this cell line properly (I will end up being trial and error). On the other hand, I have not seen reports on difficulties with AC16 but I will need to buy them because nobody I know seems to work with them, and they are expensive. Is it worth making that investment? Or should I just stick to H9C2?
Any advice will be wellcomed

Entre los estudios críticos a la innovación, dos pudieran ser convergentes: innovación por resistencia (Thomas et al)['] e innovación por distanciamiento (Herrera & Jimenez, 2013[¨]).
La propuesta es poner a prueba esas posibles convergencias (entre resistencia/ distanciamiento) en el análisis de una de las llamadas en Latinoamérica enfermedades huérfanas: El Chagas.
Nos interesaría responder en un análisis de caso abordado entre Argentina y Colombia a la pregunta: ¿Cómo ha resistido la universidad, distanciándose de jugar en redes internacionales de tecnologías excluyentes?

"At the just-concluded WTO meeting in Argentina, India and a group of developing countries blocked an initiative that would have ushered in a 20-year moratorium on levying duties on electronic transmissions – especialy from Spotify, Netflix, Amazon, Google. In response, a number of developed economies, including the EU, UK and the US, served notice that they would work towards a deal, outside the WTO, among themselves to aenhance 'the export of digital services without costly customs duties'. Is this good for internaional trade and the survival of WTO?
We are trying to apply the Method of Transfer of Benefits from the results obtained from the Contingent Valuation Method to obtain the value of ecosystem services of provision in native forests in Argentina. Thanks
They do not want to send me a free sample to Argentina and I have no references on whether it actually works on mouse brain tissue for immunofluorescence.
A number of highly visible cases of corruption have emerged in Brazil, Argentina, Peru, Ecuador, and other Latin American countries. At a first glance, these cases fit well with your work on Asia, and the general expectations of you settlements approach to development. My previous work on the Ecuadorian and Bolivian states show that the institutions that would hold corruption in check did not emerge in the past decade, despite the rethorical commitment of the progressive parties in power. Is there a window for cooperating in this issue?
I need this questionaries to evaluate physical activity level in older adults in Argentina.
I want to compare these questionaies with RAPA and YPAS.
Dear Professors and colleges in academia, I'm writing my master degree thesis about SSR in Argentina. I would appreciate sending me any references.
In the Argentina Pampas region, several agricultural land were flooded due to high rainfall and the rise of the water table. What engineering techniques can be applied to prevent flooding in plains?
I need to know how the molting pattern of the genus Akodon in northwestern Argentina is, that is, if the fur molt one or more times a year and in what season.
I would appreciate information from other species of any related genus, or even of the subfamily Sigmodontinae, or the family Cricetidae, in the subtropics.
Could some colleagues please suggest a place where I can find high resolution
climate simulations for South America?
I'm looking for something with a resolution of 0.25 x 0.25 or better, covering
southern South America.
I'm collaborating on a project to update the wind hazard map of Argentina using
climate simulations. I'd appreciate any tips regarding high resolution climate simulations to complete the project.
