Currently, certain companies/sectors are obliged to participate in the EU ETS. While some companies don't fall into the scope of the EU ETS, I wonder if they can voluntarily participate by purchasing allowances from the compliance market, i.e. the compulsory market?
So far, I only found contradictory sources online.

Hi, I try to come up with research question for my master's thesis. I would like the topic to be connected with environmental economics, sustainable development etc. and to provide some added-value to that field of science.
What, in your view, lacks research in this area? What are the questions that still needs answer or additional exploring?
I consider: ETS market, Environmental Kuznets Curve, decoupling, game theory in the context of climate policies, discount rate in DICE models, how to apply degrowth economically...
but I struggle to find something specific.
I'd really appreciate some advice.

Dear All,
I used my taper data to fit a variable-form taper model Kozak 2004-2 ,which is a nonlinear model. The data is longitudinal data that is irregularly spaced and unbalanced.so we need to overcome the inherent autocorrelation by using continuous-time autoregressive error structure CAR().I read some papers in which the authors use SAS /ETS to fit the models.Take A.Rojo2005 ,for example.In A.Rojo(2005),the author incorporated CAR(2) error process into the models to minimize the effect of autocorrelation inherent in the logitudinal data.I did like what Rojo said in the paper.When I add CAR(1) to the model, I can get the result of autoregressive parameter ρ1 .But when I add CAR(2),It is difficult to converge for ρ2.
Could someone can help me to incorporate CAR(2) into Kozak2004-2?
I add the paper A.Rojo(2005) .Thank you very much.
Here are my SAS codes

Answer
The use of temporal autocorrelation models is not a satisfactory solution to taper data. This is because the errors have a certain structure: for example the residual for height 1 meters is negatively correlated with residual at 2 meters, and the residual for height 1.3 meters is always zero and in general, residuals below breast height are negatively correlated with residuals above breast height. We have some discussion and references about this in chapter of 12 Mehtätalo & Lappi (2020).

We recently undertook a thorough mapping of the various measures that support energy-intensive industries (steel, cement, chemistry, ...) in Flanders. As part of our work on the industrial climate transition.
We are now looking for similar analyses of other countries, notably France, Germany, the Netherlands and other European member states. So far, the results has been relatively meagre, but we suspect that many such studies have not been published through academi channels, nor in English. So we've probably missed a lot.
Has anyone come across such reports/data sets/... ? We are interested in measures related to: their energy and fuel use, tax breaks, ETS-related compensation schemes, (green) investment subsidies, other environmentally relevant supports/subsidies, ... .

ETS has launched their successful iSkills test about 10 years ago to assess digital information literacy. Now they have a short notice on their web site: Effective December 31, 2016, the iSkills Assessment is no longer available. Do you know, why they killed iSkills and which new instrument is going to replace it?
Relevant answer
Answer
In my particular context, the only reason a person would take such an exam is whether the passing performance on the exam would lead to something tangible on a certification or license. There are many and interesting ETS exams that have little import on teaching credentials. I was an initial fan of the test as digital fluency and critical thinking seemed to have some cache in 2011, and was hoping that our tech courses could have this exam as a summative assessment (costs money), however, the states and accrediting bodies just didn't move in that direction in the US.

I'm trying to amplificate a nuclear gen (ETS), and it seems that I get a good band. But there is a short smear or a diffuse band above it, and I'm not sure what is happening. I tried to use everything new (buffer, dye, etc), and it diminished but it didn´t dissappear.
What could be the reason for that smear?
Relevant answer
Answer
I recommend that you need to analyze your amplified products with a set of controls such as positive control, negative control and also the ladder, as these are missing in the gel. This gel pic does not reveal whether you have got the right poduct size, whether your PCR reagents are fine and other related questions. Also, as others have recommended there could be DNA and RNA contamination, and I hope your procedure for DNA extraction takes care of this. Ideally you need to first analyse your genomic DNA, whether it is of good quality and further try to work out the concentration of DNA needed for your amplification. Further, one of the main reason for getting a smear would be high template concentration in PCR. Try to reduce the concentration of genomic DNA and standardize the ideal concentration needed.

Hi,
I want to find the dispersion energy from the ETS in ADF. Please find the attached image where the author calculated dispersion energy using ETS scheme of ADF.
Relevant answer
Answer
Hi, the dispersion energy is just a correction term which is not further decomposed with EDA or ETS. If you use a dispersion-corrected functional like PBE-D3(BJ), the dispersion energy between your two fragments will be printed.
Hope this helps,

Corrosion Inhibition of Titanium in Artificial Saliva Containing Fluoride
 Latifa KINANI and Abdelilah CHTAINI*
Abstract
The objective of this study was to demonstrate the effect of eugenol on the titanium corrosion in artificial saliva enriched with eugenol at different concentration. The corrosion behaviour and titanium surface characterization were investigated by electrochemical measurements and SEM.
Keywords Corrosion; Titanium; Fluoride; pH; Eugenol; SEM.
Conclusion
 
Behaviour of titanium in a solution containing fluoride and eugenol were studied electrochemical properties, surface analyses by SEM and pH. These results are summarized as following:
1.       The corrosion resistance of titanium specimens solution containing. Fluoride decreased in comparison with that in a solution not containing fluoride. Adding eugenol to the solution resulted in preventing the corrosion of the titanium from the fluoride.
2.       The rate corrosion of titanium in acidic medium saliva (pH =2) was clearly lower than that in the solution containing fluoride at pH = 2.
From these results, the effects of eugenol are not only the protection of titanium from fluoride attack but also the suppression of dissolution of titanium ions via formation of the eugenol films. These effects evidently suppress the corrosion of titanium by fluoride.

We are studying a material of Hyalosira delicatula but we cannot find studies about its morphology except those mentioned. We would be very thankful if someone could help us. Thank you in advance.
Relevant answer
Answer
Dear Inés:
I thank you very much your kind e-mail. I am including a summary of the history of Hyalosira delicatula Kützing that finish with the resurrection of the genus Hyalosira. I hope it was interesting for you and other colleagues.
Best regards.
Eugenia
The genus Hyalosira was erected by Kützing (1844). Grunow in Van Heurck (1881) transferred Hyalosira delicatula to the genus Striatella Agardh under the name Striatella delicatula (Kützing) Grunow. Subsequently, Round in Round et al., (1990) removed from Striatella several species, among them S. delicatula (Kützing) Grunow to the genus Microtabella Round as Microtabella delicatula (Kützing) Round. Navarro & Williams (1991) argued that the new genus Microtabella is illegitimate because the taxon to which it was applieddefinitely included the type of a name which ought to have been adopted under the rules. Thus, Microtabella delicatula (Kützing) Round must be placed on the resurrected genus Hyalosira as H. delicatula Kützing.Recently, Lobban & Ashworth (2014) excluyeron a Hyalosira interrupta (Ehrenberg) Navarro del género Hyalosira y restablecieron el género Microtabella Round emend. Lobban & Ashworth con M. interrupta (Ehrenberg) Round como especie tipo.
