“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.

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.
Relevant answer
Answer
Are we absolutely sure that the tests have been done according to the prescribed protocols? What is the test failure rate? The reliability of the tests is certainly not 100%. It is therefore possible that the test carried out on any of the crew members has trivially failed. In fact, whenever possible the test should be repeated after a few days, and in any case a blood test must be done to diagnose with certainty the presence of the virus or its absence. In other words, if the swab test shows positivity to the virus, it is certain that you have been infected with COVID 19 with or without symptoms; vice versa, if the swab test shows negativity to the virus, there is no certainty that we are not carriers of COVID 19. The viruses found in the stool or in the wastewater do not seem capable of infecting anyone, as Anju Kaushal has already explained.

Question

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.
Relevant answer
Answer
This is the answer from Paul Berrisford regarding the discontinuities in 2m temperature (which don't appear in radiation).
The ERA5 data on the CDS disks comes from the analyses unless that parameter is only available from the forecasts. The data assimilation system, which produces the analyses including temperature, uses 12 hour windows from 9 - 21 UTC and 21 - 9 UTC, the following day. The analyses should be smoothly varying during each assimilation window but, potentially, there could be discontinuities on going from one analysis window to the next ie from 9-10 UTC and 21-22 UTC. (This agrees with the discontinuities) As you say, we have already documented such cases for u and v. When these were discovered I did check temperature and it was fine. However, that was only for a couple of locations where we had problems with u and v. Therefore, I can't rule out there being problems with temperature at other locations.
The radiation data comes from the forecasts. There are two forecasts per day and in the CDS, forecast steps 1 to 12 are used from the twice daily forecasts to populate the 24 hours of the diurnal cycle. These forecasts begin at 6 and 18 UTC, so there you might expect discontinuities between 6-7 UTC and 18-19 UTC. Fortunately, you don't appear to suffer discontinuities here.
One possible solution to the temperature discontinuities would be to use the forecast temperature instead of the analysed temperature. This data is in MARS and can be accessed using the CDS API, see:
However, there are disadvantages to using forecast temperatures, namely that the influence of observations is less, only influencing the initial states from which the forecasts are run. For example, the model tends to be biased cold at low levels, so in many regions the forecast temperatures are lower than the analysed ones.

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.
Relevant answer
Answer
Muchas gracias por los comentarios, ¡es bueno dialogar!. Pero, quisiera que leas nuevamente el cuadro de desequilibrios y lo que he dicho cuando cité al presidente del país que cree que como el déficit fiscal operativo es nulo asegura que todo irá bien y aprovecha para negar que estamos decreciendo. Hoy publicaron el dato oficial del superávit operativo de 9.0 mil millones de pesos en febrero pero como el déficit financiero que lo incluye es de casi 5.0 mil millones de pesos, significa que los intereses pagados han sido de 14.0 mil millones de pesos. Y la deuda crece a tasas astronómicas. Agrégale que es notorio como la demanda de dinero para transacciones cae y ¡los precios suben aún cuando la base monetaria disminuye! Disminuye la oferta de base con una inflación mayor al 50 %.!!! O sea: estamos en la tasa de inflación que el Nobel R. Mundell define como indicador de hiper inflación: más del 50 % anual, y no es raro que el multiplicador de la base suba!. Agrego lo que ven mis ojos: la gente vuelve a sus hogares después de cobrar sus ingresos mensuales, saldar sus cuotas (algunos muchos no lo hacen ya ) y, con el resto que les queda: comprar provisiones para lo que pueda del mes entero. La velocidad de remarcación de los precios en los negocios que siguen abiertos es total, cierran y cierran muchísimos. Seguimos con que para sostener un valor del dólar que subió más del 120% en un año la tasa de interés del BC está en 70% anual. Esto no es un escenario de convocar a la gente a conversar para ser más competitivos, juntarnos todos y dialogar, es un escenario de pos guerra como en los países europeos después de la llamada 2da Gran guerra en los años 40 y, acá se debe a una redistribución de ingresos y riqueza regresiva en desmedro del mercado interno, en contra de los asalariados y pensionados, más el olvido de la atención a las funciones in delegables del estado en la salud y educación. La generación de pobreza que se ve implica tener no solo el dramático standard actual sino que es crear más población no educada ni sana a futuro por lo cual ya los profesionales de Colombia, Venezuela, africanos: muchos de Nepal, que huyen de sus desangrados países, son incorporados al mercado de trabajo informal que crece mientras el mercado formal va en caída. ¿Se entiende de lo que hablo y advierto?

Hi Gabriela,
RNA isolation can be done by simplly by Trizol method and purifying by RNAeasy kit.
Key point is homogenization of cartilage. Our lab colleague clipped cartilage pieces from rabbit knee with scalpel and placed all the pieces in stainless steel grinding jar containing some trizol (jar placed in LN2), and vibrated on the Tissue Lyser II with some specific speed for 30 secs or so. The information of Tissue Lyzer II and stainless steel jars is as below:
After that he isolated RNA using Trizol protocol and purified by RNAeasy kit. He got the best RNA all the times, I was super impressed.
If you do not have this Tissue Lyser II, you can crush your cartilage to very fine powder in the presence of LN2 by using a mortar and pestle (your hands will feel cold due to LN2 by doing that, take it easy), that will work too (we have done with human cartilage)

Hi!
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
Salomé
Relevant answer
Answer
Depends on your goals. If you intend to study human parasitic inf.,
(AC16) will be better as it is HUMAN cell line, so the results will be more comparative comparing to mice cell lines such as (H9C2) or (HL-1). Culturing cell line should not be that dilemma as you have a previous experience with culturing techniques in general. You can follow the culturing guidlines easily which come from the manufacture. Notice that any new cell line you use, you will need to adjust your first few runs, so if the price difference between them is big I think going for another cell line is a wise choice. Final issue, try to contact an author who used these cell lines before if you have more doubts regarding their usage.
Good luck

If you address the sustainability as a range of suitable balances you collect a lot of changes and interactions leading to that state. The existing knowledge (old and new knowledge) leads to intervention therefore action. A combination of purpose coherent actions is categorised as practice, good or bad both are useful for learning. The outputs and outcomes of practices could and should influence the behaviour, particularly by their present and potential future impact. These outputs and outcomes resulted from actions and practice generate new knowledge that further influences the behaviour. Theoretically it is not impossible to separate the constituents yet the question is - to what purpose?

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?
Relevant answer
Answer
Yes, without these countries, the research of corruption in the world is incomplete.

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?
Relevant answer
Answer
may attempt for creating avenues for large scale artificial ground water recharging by facilitating vertical movemnet as fast and as much it can be...but all depends on local site conditions...the excess parcels of flood volumes needs to be safely economically and rapidly shifted to ground water bodies even may be in wells or local acquifers. this could be one innovative way to dampen the flood peaks atleast....
the excess water if any way diverted or spread over the adjacent forest or grassed area it will be relatively a easy task...
