Look for exploring geology

I did. I earned my own publications on ORCID, but not on Google Scholar!

The range of spatial resolution you are talking is availble but not free of cost such as Compsat, LISS-IV, Quick bird, Planetscope etc. Free of cost data from Sentinel-2 available at 10 m spatial resolution which could be benficial for you. Please try.

You are most welcome for further queries.

Rice is traditionally grown as the puddled transplanted crop. Puddling destroys soil structure increases compaction, and reduces deep percolation of water. This reduces moisture storage in soil profile and also aquifer recharge. In permanent zero till rice wheat system, rice can either seeded or rice seedlings can be transplanted in slits opened with zero till drills, thus obviating direct for puddling thereby facilitating conditions conducive to recharging soil profile and ground water during monsoon.

I feel research should start with an objective preparing certain questions to investigate. while investigating, all the necessary related information in the name of review of the literature to be collected and finding the results drawn from their research. while establishing their findings, they might suggest their scope and scope for further research. The fresh researcher should start his research from where the previous researcher stopped and suggested further research.

Mostly when it is

out of scope

Not original

Not novel

The similarity index is high

Dear Jiachen,

I recommend that you use pharmacological blockers to isolate your currents of interest (CNQX, APV, picrotoxin). It has the advantage that you can also check whether or not your recorded currents derive from specific ion channels, and it may eliminate your EPSCs.

Good luck!

Sunny Zh , you need to use the recommended 2 POSCAR images recommended from neb2dim.pl to obtain the MODECAR. The MODECAR can be obtained using modemake.pl in the form below:

modemake.pl POSCAR1 POSCAR2 (then run to get the MODECAR in the current director)

Good Morning Bashaeir M. Almutairi re: reviewing an article of mine in Cureus

I urge you to read the Mar 22, 2016 response to this question: Choosing Reviewers for Paper: Andrew Davis @Andrew-davis-46

As he points out, in most legitimate cases, "reviewers work for the editor, not for the authors"

I am not a specialist in your field, but if you would like a collegial review and feedback (not a peer review) please feel free to message me here on ResearchGate.

You can go through the following chapter. It might be helpful.

Even I checked about pencis conferences, they have a valid website with conference details and support team..I think it's a private platform that gives awards to latest researches so that they can publish those data in their journals..Pencis has their own journals too..I even checked in youtube..they have videos of their already conducted award ceremonies..I don't think it's a scam, its just a private platform trying to advertise their company through researchers..

Dear Terence Tan ,

I like to add a warning: the website https://www.resurchify.com/looks misleadingly trustworthy, but I see a number of disturbing things with this website. For example, in their list of journals https://www.resurchify.com/e/journal/all-categories/all-countries/all-years/page/1/there are suspect ones like (just check a couple of pages):

-International Journal of Information Technology, Control and Automation https://www.resurchify.com/ed/ijitca-2021-international-journal-of-information-technology/10285 https://wireilla.com/ijitca/indexing.html is published by Wireilla Scientific Publications a publisher mentioned in the Beall’s list https://beallslist.net/

-Numerous journals like International Journal of Ad hoc, sensor & Ubiquitous Computing (IJASUC) are published by AIRCC Publishing Corporation which is mentioned in the Beall’s list https://beallslist.net/ as well

So, despite some interesting and seemingly genuine information they also are linked to less reputed journals and publishers. Combined with the misleading suggestion that they give impact factor info (while this is an estimate based on Scopus info) and the total absence of real contact information I do not trust this source.

Best regards.

The purpose of experiments with cells in culture is to simulate similar cellular processes in vivo. The transfer of patterns identified in vitro to the in vivo system is always problematic. The tolerances for such a transfer are obviously greater than those that have to be taken when working with cells that have been in "bad" conditions... Unless, of course, these bad conditions are associated with exposure to obvious mutagens or carcinogens.

Hi Erfan Rahimi , in time-dependent 3D geomechanical simulation ("4D" coupled flow and geomechanical simulations) there a many interdependencies between material properties (e.g., elastic properties, strength properties, porosity/ permeability, fluid properties) and simulated fields (stress, strain, pore pressure).

You have to think carefully when including additional interdependencies (or vice versa NOT including these interdependencies), whether they add (i) a lot of additional complexity, (ii) create a lot of additional insight, (iii) create complexity without creating insight, (iv) the error incurred by failing to include the interdependency. As you correctly point out, updating elastic properties in the overburden is NOT commonly for coupled flow and geomechanical modelling. This is one of the cases where you make the simulations a lot more complex, without adding a lot of insight. Elastic properties due to stress/strain changes in the overburden change by less than a percent from their initial value - and updating the elastic properties will affect the simulated stress field by an amount which is insignificant compared to our ability to calibrate the stress field. In your picture, you show a loop which includes updating of velocities for 4D seismic attribute generation. Here updating the velocities (even by less than 1%) results in something we can observe in field data in the form of time-lapse timeshifts. In a similar manner, if permeabilities are stress dependent in a significant manner and neglecting to include this coupling will create a large error, it is customary to include this coupling. Another example of coupling which is sometimes, but not always, used is to use non-linear stress-strain relationships in the reservoir, if significant compaction occurs and the reservoir rock will experience irreversible compaction.

In summary, keep models as simple as possible, and add complexity if there is a good reason. Do not fall into the trap of making models "complex" for the sake of complexity. Complex models are harder to interpret, and don't necessarily provide more insight. There is an unfortunate tendency of assuming that "complex" models are "better" models. They sometimes are, and often are not.

Hope this makes sense, and addresses your question.

Cheers,

Jorg

Sharing the scores.

Metastatic sites may share many of the transcriptome of the original tumor. I do not think that your comparison between primary tumor and metastasis will lead you to identify metastogenes. Remember that metastasis can also originate further metastasis.

Hello Stef,

You can visit these links. I think this is useful for you.

It's simple - electric vehicles certainly reduce the environmental load in the places of their use, but increase it many times in those places where raw materials are mined, components and electricity are produced. Is the division of labor being replaced by the division of emissions?

Dear Kandi,

I recommended that the following topics can be interested in mining engineers:

- Deep learning application in mining,

- An automated smart system in mining operations and stabilizations,

- IoT monitoring systems in open-pit mines,

- Deep structured learning application in green mining.

Best regards,

Dear Hossein Zarei

I know that you selected your subject since you asked 3 years ago, but I am answering here for new readers.

Set some topics that you interested

Read some new papers on the subject

Find a theoretical basis about the subject

Look for some aspects that you can make a difference

Don't limit yourself to special subjects

Try to find a subject related to new ideas ( Smart Mine, Robots and drones in mining, Sustainability and environmentalism, deep-sea mining,

Also, this paper will be useful:

Yeah. I think that is normal to cite. You can also check the plagiarism of your final manuscript through some free websites:

I think there is some precipitated stuff in your loading mixture. It can come from an overloading amount of protein or a low-quality loading buffer. Make sure that your loading buffer is even. Additionally, you can filter your lysate after centrifuge for sure.

There are numerous methods to calculate the density of punctiform, linear, or aeral surface expressions in numerical geography or geomorphometry. The latter discipline provides tools and services how to do so (see Evans, Minar, Cullum, Rogers, Dragut, Blaschke......). Using the afore-mentioned disciplines as keywords will help you to get approximated to this issue. It is only a tool-service. As an economic geologist being also engaged in these disciplines I cannot decide whether your approach and my recommendations really fit your goals.

At 900 m depth, the only viable mining method is by block cave. However, this is a small deposit, ~2 Mt Cu, and so the capex needed may not justify the development at the present Cu price..

I agree with Nabodita Sinha !

If black matter is actually the sum of all existing primordial black holes (pBHs) (https://scitechdaily.com/black-holes-could-be-dark-matter-and-may-have-existed-since-the-beginning-of-the-universe/), THEN my proposed bhCE would more plausibly explain the universal accelerated expansion of our universe by the pressure exerted by all these pBHs (which pressure is the reaction force of my B-associated Casimir force).

I have had the same problem, couldn't work out a reason why I could tag some and not others.

Olga Rauhut Kompaniets Thank you for your response. I will try TRYNET.

Hi Manuela Frontera,

I don't think it's related to ELAN... Are they using a file you shared with them? If so, make sure they first extracted it from the compressed folder or downloaded it from the sharing paltform you are using (if it is the case) and stored it in their computers... If they are using a file of their own, do they have admin permissions in the computers they are using? I think this might be related to this type of technical issues... Hope this helps you!

Regards,

Marisa

To account for the impact of certain factors on a dependent variable, just include them in the model. As an example, suppose you do a regression on a dependent variable y and an independent variable x. You believe that z has an effect on y as well and want to account for this impact.

Dear Blessing Olamide

Please kindly follow the attached and following references, hope you can find your answer!

Spearman test is for 2 rank-ordered( ordinal) variables. You may try Eta correlation

In this article we look at these issues, I hope you find it of interest.

The acceptance of your article will entirely depend on the scientific contributions in terms of the suggestions you give after a thorough analysis of what has been done so far in that area. I doubt whether your work will be accepted if you just state what has been done and then fail to chip in and give your expert opinion of what you thin is the trend, and or give some insightful suggestions on how the identified challenges, if any, should be addressed.

Dear Khikeya, very nice question!

Due to Algal capacity to remove heavy metals, as well as some toxic organic compounds, therefore, it does not lead to secondary pollution. Please kindly read the attached file , it may be very helpful !

Hello dear,

I didn't understand clearly what you mean.

if you want to model groundwater sources, you can use RockWorks RockWare software. take a look at : https://www.rockware.com/hydrogeology/

I am in a similar situation. Thanks for highlighting Aruditya Jasrotia

Hello Neil,

Thank you so much for taking the time to answer my question. I really appreciate it.

I will definitely take a look at what they have in Papua New Guinea since I did not have it as a benchmark.

The examples you shared at the end are a clear example of how some big mining companies have taken the lead on improving ground control practices around the world. These will be very valuable resources for me as well.

I really appreciate your input.

Sincerely,

Juan.

this is a wonderful idea, and I am Interested in the Geotourism area.

According to the conclusions of Zhvanetsky, an intelligent person never argues, because everyone has their own truth. He does not burden anyone with his problems, because he avoids them and is ashamed to admit that they exist. And, finally, an intelligent person never reproaches his interlocutor for anything, does not ridicule his shortcomings, does not criticize and does not give value judgments to other people's actions.

Are there such people among your interlocutors?

If your are interested in good visualizations I recommend you to see this application: TerriStory.fr

Sure you can't do that with hmmer. You may want to try HHBLITS.

Dear Jecel

highly recommend these topics and references :

The last reference include 37 nice topics!

In case you want to try in the direction of AI:

Normally, equipment is selected after trade-off studies. The main factors to be considered are:

1. Suitability considering the sizes of the developments, mine production rates etc.;

2. Economic comparison (NPC, CAPEX, OPEX etc);

3. Constraints like ventilation, cage size for transporting underground etc.

If the equipments is not selected properly, it is most often due to the competency of the people who made the selection. Sometimes, it is due to the low level of exploration and research done on the deposit, or even wrong selection of access, mining method etc.

Changing equipment from one to another is a complex task and again requires a trade-off study with technoeconomic comparison considering all the constraints.

The Cu-rich “Tsumeb-type” deposits can be taken as reference of a special type of base metal deposit. The type – deposits is hosted by Neo-Proterozoic platform

carbonates of the Otavi Group, Namibia.

Complex Ge–Zn–Pb-bearing limestone-hosted Cu deposits occur within dolomites and calcitic limestones, within clastic sediments and evaporites of tidal (sabkha), lagoonal or lacustrine depositional environments which evolved in a rifted continental margin and intracratonic platform geodynamic setting.

Germanium occurs as Cu-thiogermanate minerals (e.g. germanite, reniérite, Ge-colusite) in massive As-rich Cu ore (tennantite–enargite association). Deposits formed by the reaction of hot fluids passing a variety of aquifer systems, where they became saline and enriched in metals. Eventually, the metals were precipitated in karst pipes and breccia horizons.

Lead may increase at the expense of Cu, new elements such as V entered the scene and thereby opened up a new field of carbonate-hosted base metal deposits as at Senge, DR Congo where V was seeping down from overlying carbonaceous schists and giving rise to descloizite–mottramite. Many small stratabound carbonate hosted Zn–Pb deposits within Aaleno-Bajocian dolomites near the Morocco-Algerian border region of northern Africa may be attributed to those deposits.

They bridge the gap to carbonate-hosted Pb–Zn deposits, especially to the so-called Alpine-type deposits where Mo is held to be a marker element.

Dear and respected Prof Christian, I have an unfinished project on it and due to depend on the cost-effectiveness of removal and salvage, ....... it is not completed , if can be useful I would be happy to share it.

It is always wise to have structured questionnaire in a survey. I am not quite sure about your research topic and possible outcomes. But, if you include structured questionnaires then you are likely to get desirable outcome.

You may have different perspective than other writers. It is always wise to review the available literatures on your own. For this, please try to go through previous researches and analyze them. Obviously we need to have a clear idea on what others have done before. Please make sure that literature review section includes relevant points only.

Salam Mr. Mohammed.

It's a quite general question. You need to provide more details regarding the nature of this solid waste.

Initially, you need to identify the source of waste, in which are these wastes from agriculture or industrial industry? * This is basically to identify the next step.

If the waste is from the agriculture industry, you need to run a XRF, TGA, LOI analysis to understand the carbon content, chemical compositions.

The wastes generated from the agriculture industry are usually fed back into agriculture activities (e.g. as fertilizer). However, with some treatments, it could be utilized in different industries.

The second case is to be generated from industrial activities, mainly mining and oil extraction activities. In this case, the most important characterization analysis you need to conduct is the XRF analysis. Indeed, you need to assess the value of this waste and what elements could be re-extracted from the waste before it can be processed in different activities.

In short, my opinion is like that, you need to provide more information about the targeted waste and its source. Based on the source and nature of this material, specialists in their field could recommend either a standard or references to characterize the waste materials based on their perspective.

This recent paper deals with mine planning issues, fyi. Every mine is different, and each will have its own challenges.

Sajaweddin, a major issue with open-pit mining is slope stability of the pit as it gets deeper. Two major porphyry Cu-Au deposits, very deep pits, at Bingham Canyon, Utah, and Grasberg, Irian Jaya, had failures that stopped mining for many months. You might consider this topic. I attach a paper on mine planning, with open-pit mine examples, that may give you some ideas.

It depends on the number of mining areas. If they are few there is no need for sampling but if there are many then you can use fishers method for sampling.https://www.geopoll.com/blog/sample-size-research/

Not sure

Many software has optical data structural analysis. For example Well Cad and IP have special modules for fracture system analysis.

There are some TBMs in mining projects (I personally I have participated in pre-feasibility studies and it is becoming a more interesting/feasible excavation method in mining access and developments). What to say in Stillwater mine, used for many years now!

According to the following paper, around 100 TBMs have been used in mining projects (2016) but those are already published, it might be presumed a few more. Obviously, if we compare with civil tunnels, the difference is significant.

It´s true, that pure quartz crystal can be found in many placers around the world today, but even today, they don´t have a large pure crystal everywhere. Large crystal is for my question : high 35 cm+, weight min. 9 kg.

Today, but in medieval Europe?

I am exactly ask, you live in year 1350 in central Europe and need a large colorless and pure quartz crystal. Where can you find the stone? I think the most likely is in Swiss or in the Alps, but the exact place - mine, canton, village, .. is?

You could contact Dr. Anthony Christie (T.Christie@gns.cri.nz ), now retired from the NZ Geological Survey, an expert in the nature of the metal deposits of New Zealand, and most aspects related to mining in the country. With regards to banning mining, if this comes about, the computers we are using (consisting of dozens of metals) will not be replaced; the mobile phones that are produced (over 1 B/year) in the world will be no more (the iPhone uses 62 elements to make one phone, with many being critical in that they are the only metal that enables certain functions); of course, we could consider cars, buildings, roads, power stations, etc.; and all of the green energy sources (renewable energy technologies such as wind and solar require four to six tonnes of copper per installed MW); a petrol car needs 10 kg Cu per vehicle, whereas an electric car consumes 40 kg Cu in its production. So banning mining is not the answer, nor is it anywhere near an option. Fundamentally, banning mining results in the export of the issue to other countries while continuing to import metals for industry, construction and consumables. This is why the EU now is encouraging metal production from within its borders.

Hi there, there are a few cases of ecological restoration in New Caledonia, however it might be useful to ask for this paper :

Dear Ahmed Mousa,

Steel fibers are short discontinues strips of specially manufactured steel. Generally, their inclusion in the concrete improves the mechanical properties of concrete significantly. As the most common matrix, which is now mostly use in construction industry is Reinforced Cement Concrete. Main Reinforcement purpose is to resist bending due to applied load.
