Migration - Science topic

What is cloud migration in cloud computing and what are 7 Rs in cloud migration planning?

Why did Hamas suddenly attack Israel? Did he not know that the Israeli response would be hideous? Knowing that Hamas planned this attack with the help of international forces with regional and international dominance, broad plans, rational minds, and complete secrecy. Did they not take the results into account? Why did Hamas suddenly attack Israel?

The answer is simply the huge amount of gas reserves at the bottom of the Mediterranean Sea on the coast of the northern Gaza region, where the presence of natural gas reserves is estimated at more than a trillion confirmed cubic meters, which has not yet been confirmed, perhaps trillions and much more than what has been announced. Who knows except Israel and let us assume Türkiye?

This huge amount of gas is within Israel's reach, and it is easy to ship it to Europe, which is thirsty for it. It is certain that Israel will seize the opportunity to occupy and exploit it, and anyone who stands in its way.

Russia, preoccupied with the Ukraine war, is planning a deal to guarantee the lands it occupies in exchange for ignoring Gaza gas. China is far away, waiting to prey on Taiwan in exchange for its silence. The European Union is the silent beneficiary, and America is Israel itself. They rule the world, and the rest are the weak and the ruled. Among those affected are the rival country and Turkey. The truth is that Hamas was quick to launch its surprise attack. Hamas was certain that Israel would invade the gas fields on the Gaza coast, whether Hamas attacked it or not. Israel was occupying northern Gaza and its coast without discussion, ignoring all the great powers in the world.

As for Hamas, it attacked with the aim of revealing to the world that Israel would occupy the gas fields in Gaza in broad daylight, so that the whole world would be aware of what is happening in Gaza, and so that the countries of the world would know and bear witness. Serious violations and clear Israeli encroachments on Palestinian natural resources. If the issue is moving from economic geography to political geography, then there is certainly no ideological war there.

For this reason, Israel requires the residents of the northern Gaza region to leave the northern region to the southern Gaza region, and Hamas does not want the residents of the northern region of Gaza to migrate to the southern regions of Gaza. Egypt does not allow them to migrate to Sinai, and the Arab countries will not accept the displaced, and Europe is silent. Or is Turkey and Qatar inflaming the feelings of the world and the people because they are the most economically affected by what will happen? Iran does not respond equally, fearing that it will fall into a trap, and the Kingdom of Saudi Arabia is the silent beneficiary.

Starting from Ukraine, through the Republic of Niger in Africa, to Gaza, all these events are interconnected, like the thread that ignites gunpowder. Will the Gaza gas spark reach the borders of India, Pakistan, or Serbia, or where will it reach for the big bomb to explode?

All this is the painful truth, but the most important question is what next? Have we really entered World War III or not?

It is certain that Israel does not want to occupy the entire territory of Gaza, but rather intends to occupy the northern Gaza region and its sea at any cost. If Israel occupies northern Gaza with its coast in the Mediterranean Sea and guarantees its occupation of the treasures of gas fields that many, especially Turkey, covet, it will declare the end of the invasion and there will be a truce.

So what can stop China's red dragon? When they prey, they are deaf. Will Taiwan attack the source of technological chips or the source of artificial intelligence, which is the magic treasure of world domination and domination?

If we avoid World War III, what will happen politically and economically?

Will global economies collapse and will there be a financial crisis that destroys global financial markets? What about the worsening debt crisis in the world?

What's the solution? Isn’t the ideal solution to return to the United Nations and become a single global state and renounce all international conflicts, and the countries of the world agree and each of them lives in security and coexistence, and we deal with our humanity as a means of giving birth to a new world order based on artificial intelligence and absolute justice?

We are working on kink nucleation and migration using NEB method in LAMMPS. To provide intermediate replicas we need to make kink pairs. Can anyone suggest a method or tool that can be used to make double kink.

Hello Everyone. In the model-driven reverse engineering context, I've found out that generating a KDM model is the best way to respect the OMG standards in order to migrate an android app source code to iOS. I also found out that MoDisco tool is the best tool to generate the KDM needed but the problem is the lack of documentation and tutorials of that tool. How can I integrate my android app metamodel into MoDisco and use it to generate the KDM ?

DVM, Carbon cycle,

I got comments for my manuscript: For migration assay (checking cell-cell interactions), the authors only used transwell. More approaches should be included.

Can I ask does anybody know other methods for migration assay (not transwell based)?

Want to do migration assay in T047 D cell line , please suggest protocols

I know that both Orange G and Bromophenol blue are negatively charged dyes and that Orange G may migrate faster in an agarose gel.

I found a resource that says Orange G can be used in Native-PAGE and in a DNA PAGE but I cannot find any resources that say whether the two dyes are interchangeable in a protein SDS-PAGE.

Any insight would be greatly appreciated.

Hi all, apologies if these are very basic questions, but I'm fairly new to FACE.

First, I've seen multiple papers using FACE to separate disaccharides. It is possible to separate chondroitin-4-sulphate and chondrotin-6-sulphate disaccharides, however, I do not understand how this is possible. Both GAG chains are are mono-sulphated, so mass to charge ratio is the same, anionic potential is the same, etc. So how are they separated?

Second, and again sorry if this is basic question, but why do disaccharides migrate in "reverse" order, such that higher molecular weight disaccharides are lower on the gel and lower m.w disaccharides are higher? Eg, ΔHA migrates slower and is at the top of the gel at m.w of 379.3, whereas ΔCS-4S has a m.w of 459.4 and is lower on the gel (m.w data from Osago et al., 2014).

Thank you all very much.

( i just found out that i could couple darcy flow and particle tracing modules, but still don't know how to model the attraction of a suspended charged solid particle to a charged matrix surface)

I am trying to understand why H. erectus initially migrated out of Africa and I am trying to understand their foot morphology and locomotive capabilities. I know there is some evidence from Ileret of footprints, but is there physical fossil evidence of a complete (or near complete) H.erectus foot?

Thank you for your help!

Hello!

I am struggling with Western blot. I would like to measure protein levels in bacteria cells, so I used western blot technique. Onto gel, I loaded bacteria lysates and the purified protein of interest (his-tagged). I performed WB. The purified protein is recognized by antibodies and has proper molecular weight compared to molecular mass marker, however, native proteins in cell lysates migrate much slower. Bacteria are lysed in Laemlie buffer and boiled at 95C before SDS-PAGE electrophoresis. I do not separate soluble and insoluble fractions of cells or digest DNA.

What could be a possible explanation for this? is it possible that somehow crude extract slowed down protein migration in SDS-PAGE?

I believe that the antibodies, which I used work properly - they recognize purified proteins and work well in ChIP. In the attachments, I loaded the WB result.

We are leaving in an era of mass Migration in any part of the World. Three days ago, many migrants from Africa and Asia have been killed in the South of Italy. The Italian authorities are trying to deal with the responsability of such tragedy. On the other side, it seems that the African Institutions are not able to explain the fact. How an entire Continent could observe its population migrate without trying any solution to stop it. What do you think about this matter? I think that International Co-opertion has the most responsability in this. African States are not able to follow their own Endogenous Development Programs. Thank you for your contributions.

This question is for creep specimens.

Hi,

I am currently working on my master thesis and I want to do a transwell migration assay with bone marrow derived macrophages in January. I have aliquots of the macrophages in liquid nitrogen storage and when I use them for different experiments, I usually let them recover for about 2 days with daily medium changes. The harvest (I scrape them off the dish) and the freezing-thawing process puts a lot of stress on them, so I like to give them this time of recovery and get rid of dead cells.

When I searched for protocols for the migration assay, I only find that the cells are grown in another dish prior to migration and then detached by Trypsin and seeded into the transwells for the migration. I would like to go around this detachment-step, as it would be additional stress for the macrophages. So could I also seed the macrophages directly into the transwells (5 µm pore-size) after thawing them and let them recover in there (including medium changes) or would they already start migrating even without a stimulus? Or is there any other way how I could go around the stress of the additional detaching?

Thank you for your help!

The question seeks to analyze the impact of immigration in Europe in different aspects and to explore the policies and measures that are being implemented to address its challenges and opportunities. Aspects such as the economy, politics and society are considered to better understand the migration phenomenon and how it can be managed effectively.

What is the purpose of resting T cells before a migration assay? Is it necessary? Do you need to have them in IL-2?

I have heard that 13% of the world speaks at least three languages (trilingual) but cannot seem to find a reliable reference. Has anyone come across any sources that talk about the number of trilingual speakers in the world? Thank you!

Following Migration types needs to analyse

1) Intra-district

2) Inter-district

3) Intra-state

4) International Migration

D-2: MIGRANTS CLASSIFIED BY PLACE OF LAST RESIDENCE, SEX AND DURATION OF RESIDENCE IN THE PLACE OF ENUMERATION - CENSUS, 2011

following file conatins in the data like

1) Last residence within India

2) Within the state of enumeration but outside the place of enumeration

3) Elsewhere in the district of enumeration

4) In other districts of the state of enumeration

5) States in India beyond the state of enumeration

On the basis of above mentioned data catagories how to cacluate diffternt types of migration ?

Hi everyone.

I have a batch of microglial cells differentiated from PBMCs that I want to use for a migration/invasion assay when exposed to some chemotactic cues. I am trying to use the Boyden Chamber (aka Transwell) system. However, since I need to differentiate these PBMCs in microglia for 10-14 days and they die if I attempt to split them, I have to plate them directly inside the transwell and keep them for very long in culture. I cannot add media into the plate well, as cells may migrate towards the external side of the transwell membrane during their differentiation.

Good time of day!

I am trying to determine whether my protein is a multimer or a monomer by NativePage.

It is expressed in e. coli as an MBP tagged version, with the option of keeping or cleaving off the tag.

It is suspected that the protein is a dimer since it consistently fails to separate from cleaved MBP on a size exclusion chromatography column (as a monomer it is about 25 kDa, so about 50 kDa as a dimer, and it comes out as an overlapping peak slightly earlier than the 43 kDa MBP).

I ran several samples on a 4-16% NativePage Novex Bis-Tris gel.

On the gel, lane 1: MBP-tagged version of the protein;

lane 2: the protein alone

lane 3: MBP alone

lane 4: a mix of the protein and MBP (cleaved off)

The green box shows the MBP position, the blue and orange boxes show the approximative theoretical MW of the monomer and dimer respectively (+/-15% to account for size estimation error mentioned in the NativePage Novex Bis-Tris gel system protocol).

Off the bat, the MBP appears to be heavier than the expected 43 kDa, despite being a globular protein and having an acidic pI (so theoretically migrating relatively fast). It also comes out as two bands (three if more protein is loaded) - which I am assuming is due slight conformation differences? (should not be due to gel quality, it is new and was stored at 4°C).

So already, the first question is, why does MBP appear heavier?

The protein is even stranger, as it appears much heavier than a dimer (related proteins can be monomers up to tetramers, but are usually dimers). There is no obvious reason for it to be migrating much slower (it has a pI similar to MBP, it's a soluble protein, not a glycoprotein and there shouldn't be any glycosylation). My only explanation besides it being a higher multimer, is it possibly having a shape that slows down migration (no structures available in the literature, so can't confirm). But can protein shape alone slow down migration that much?

There is some salt in the protein alone and protein+MBP mix samples, but below 50 mM (as required per protocol), but no salt in the MBP-protein or MBP samples (I've read this can affect migration).

Alternatively, if it is a higher multimer, then why doesn't it separate from the MBP by size exclusion chromatography?

Has anyone else had problems of proteins seeming inexplicably much heavier on a Native gel ?

We assume that they perform only two degrees of freedom, as shown by experimental evidence.

Let's say I have a population consisting of two patches. In addition to recombination in each patch, there is a probability of migration between the patches. How can I incorporate migration into the Wright-Fisher model?

I am looking for Machine Learning based migration papers, there doesnt seem to be that many??? I have already seen Micevska 2021, Best 2022, Kiossou 2020, Guy 2021, Molina 2022.

Are there any more?

Thanks!

Does anyone know why the non-steady state chloride migration test (NT BUILD 492 nordtest method) is only applied on mortar and concrete specimens? Has anyone tried this test on a paste sample before? I want to learn this so I can do microstructural analysis on samples after exposure to the chloride test.

Thanks...

Hello everyone!

I am performing migration assays using SW480 cell line in type I collagen coated plates.

I normally add collagen solution into the plates, incubate 1 hour at 37°C and then remove the solution, let them dry and use them. But now I was reading that collagen polymerization needs a base (such as NaOH).

Do you use NaOH or something similar? How can you confirm that collagen is well polimerized on the plates to use it as a migration substrate?

Thanks in advance !

Hi everyone,

i'm writing my thesis on bilateral migration flows using a Gravity Model and I'm new to the topic. I'm using country and yearly fixed effects. Can I include a control variable on distance?

Thank you.

I am doing a Transwell experiment to look at monocyte migration. The cells are migrating to the bottom of my plate and some adhere some are suspended. I would like to count the cells without removing them with accutase or scraping to avoid losing cells. I have looked at CellTiter-Glo as an option. Are there other options that work better?

I am an international student and I am studying sociology at McGill University.

I am interested in the sociology of immigration (in particular, immigration in Canada) and have read research papers about this topic. However, I feel I'm stuck generating possible research topics for my final Master's research paper (it will be 30 to 40 pages long).

Does anyone have any exciting immigration study subjects in Canada for a Master's research paper? I am looking for both qualitative and quantitative research topics.

I also would appreciate it if you could introduce any interesting papers about immigration, mainly, in Canada

I'm doing a research on migration process and history of migration and looking for scientific specific data about what kind of challenges migrants can face in foreign countries

Hello,

I am working on the immune response in the respiratory tract 30 minutes after a stimulation, and I'm also analyzing the bone marrow. I observed a rise in the number of Lin-, MPP and CMP, but I'm wondering if 30 minutes of stimulation is enough to influence the BM . Does anyone know, how long it take for progenitors to "sense" the inflammation, to differenciate and to migrate ?

Thank you very much !

Hi there,

searching some sort of UNHCR with scenario analysis. Cherish your feedback.

Hi everyone!

I would like to know if you have experience with migration and invasion assays using transwells (boyden chambers). If I use type I collagen coated trnaswells, is that migration or invasion assay? I thought only with matrigel it was possible to asses invasion but if I block the pores with type I collagen and then measure the migratory cells, in fact, I'd measure the cells with the ability to degrade collagen in the pores and then migrate, right?

All comments are welcome :)

People migrate for many reasons. These reasons can be classified as economic, social, political or environmental: economic migration - moving to find a job or following a certain career path.

Migration can expose hosts to a greater number of infectious diseases, as it covers a larger area and visits more habitats than residents. However, because long-distance movement is energy consuming, migration can have a devastating effect on infected hosts, reducing the risk of infection.

What type of models are recommended to show the relationship between the migration behavior and the socio-economic status of in-migrants?

In the legal field of custody pending deportation (Abschiebungshaft) in the Federal Republic of Germany, errors happen more frequently in the lower instance, the district court. Above all, it is procedural errors that lead to decisions later being found to be unlawful, for example, a lawyer who can be seen from the files is not contacted or there is insufficient language mediation. In terms of reasons for this, the lack of time and the density of court proceedings are often put forward first, leading to a lower qualitative examination. In the same way, legal ignorance can sometimes be observed in the legal field of custody pending deportation.

I am interested in whether there are other areas of law in which similar errors can be identified at the lowest level? In other words, procedural errors that happen again and again.

hello everyone

I'm writing scenarios with fsc26

however, I have trouble filling the sample sizes in tpl files

so far I just fill the sample sizes with *2 of my empirical sampling sizes (cause my focal species is diploid so pop0=181*2, pop1=24*2)

however, these sample sizes tremendously increase the computation time to almost 1 month (I'm using Linux with 10 cores for each model)

to save computation time, will the estimated parameters be strongly affected by the smaller sample sizes I give in my scenario (e.g., only use half the original sample sizes)?

I hope to have any explanation about migration of RNA, when i finish extraction i make electrophoresis in TAE buffer with 1% agarose but the result (no bands of RNA) but after a few days when I repeat the elctrophoresis the bands are present, what's the wrong ? and I hope to have some advice please to get a good migration. Many thanks

Dear all,

I am trying to over-express some me the NaPi2b membrane protein in HEK293 cells to later run some Co-Ip. The protein has a DDK tag and seems to be expressing as I can detect a strong band at the top of the gel with a DDK antibody. The problem is that when I run my Western blot to check it it expressed the the protein seems to stay at the interface between the stacking and the resolving gel, and does not migrate to where it should be at around 76KDa. So I cannot be sure that it is expressing correctly. I have tried some methods mentioned here, where they suggested not to boil the samples before I run the gel and got relatively better results never the less there is still allot of protein stuck at the top. The gel seems to be running ok as GAPDH migrates to its correct place. I am using a RIPA buffer with protease inhibitors and my no transfection controls don't have this band so I don't know what exactly it is I am doing wrong.

I the picture picture you can see the strong band at the top of the membrane and the correct band at the 76 KDa where the protein should. The upper membrane is one in which I did not heat the samples and the lower membrane was with heated samples . Is these anything I can do to solubilize these proteins? What am I doing wrong? Thank you so much for your help

Hi guys!

Sorry for bothering. This is Haochen, MA student from Royal College of Art, London, Design Futures. I'm working on a project on fishing and hunting communities in Bangladesh in 2050, and it's looking at the future impacts of global warming on the lifestyle of local fishermen. But I now have some confusions and may need more professional advice and guidance. I sincerely hope to get feedback and comments from you, which will be critical and precious to my project. Thank you so much for your patience and time to read this question!

My research focuses on the effects of freshwater river salinization caused by rising sea levels. After watching some documentaries, news, I realized that the problem of salinization of freshwater not only seriously affects the stable food and economic sources of many people (migration and extinction of many fish species), but also directly affects their health (access to drinking water). Finally, I would tell a series of stories of Bangladeshi fishermen in 2050, to show what their dilemma could be, what their future lifestyle would be like and what tools they would use under the influence of freshwater salinization. But now I'm missing some deeper insights to enrich my story, so I'd like to sincerely ask you some questions. thank you very much!

1. Regarding fishing: If in the southwest coastal rivers of Bangladesh, will the salinity of the rivers change significantly in different months of the year? If so, how much change could be happened? Does this monthly salinity change depend not only on monthly precipitation, but more on local geological conditions? And will this change radically affect the migration of fish and thus affect the harvest of fishermen?

In 2050, with the possibility of more extreme weather, is it possible that seasonal or monthly changes in the salinity of a river will be more dramatic than today, forcing fishermen to move more frequently to maintain a stable food source? Suppose that the middle section of the Pasur River has a salinity of about 5 in the rainy season, and in the dry season, the salinity of the middle section rises to 20, causing many low-salt-tolerant fish to leave or migrate, while saltwater fish are not adapted to inland channels environment, so there is no corresponding immigration from brackish fish, which causes fishermen do not have enough fish to harvest?

Does the salinity of a river increase uniformly from upstream to downstream? Is the salinity change of the river water regular or predictable every month and every year? Can we help fishermen have a more stable source of income in different seasons by measuring the regularity between river salinity and fish migration? If this is possible, what data could be measured?

2. Regarding population migration: If the river water in southwestern Bangladesh is salinized, will the local soil be salinized accordingly, making the arable land uncultivated and the groundwater undrinkable? Is this likely to lead to a large-scale migration of large southwest populations to live in the freshwater areas of the north? Combined with the question regarding fishing, is it possible that fishing and hunting groups living on migration will increase as a result?

These are the questions I am confused about, thank you very much for your patience! I would appreciate so much if I could receive your reply and guidance. Wish to have further opportunities to learn more in-depth and detailed knowledges from you guys, thank you very much!

Dear distinguished colleague,

Recently we have started comparative global research that we have started recently on 'Students' perception on the Russia-Ukraine war 2022' (link to the website: http://www.covidsoclab.org/russia-ukraine-war-2022/), covering various economic and social effects of this war. The global comparative analysis helps us formulate the most useful recommendations for policymakers.

If you are interested in participating (as a contact person and a potential co-author of a joint paper, do let me know to give you further guidelines – see also research guidelines on the webpage: http://www.covidsoclab.org/russia-ukraine-war-2022/research-guidelines/). Your main task at this stage would be to motivate students from your institution (or wider in the country) to complete the online questionnaire by 30 April 2022 at the latest (here is only a preview link: https://1ka.arnes.si/a/60ee60a0&preview=on). When we have the results, we will analyse and compare them (between countries included in our study - then is a plan to prepare academic article(s) relating to different (e.g., economic and social aspects) of the Russia-Ukraine war 2022 together with the analysed results of our questionnaire survey). You will also receive data from your country/institution in order to deploy it in further research. The detailed dissemination plan will be finalised later according to the interests of international partners.

If your time is limited and do not allow you to fully join at this moment, we would kindly ask you if you could motivate and share a link with your students to fill out the questionnaire (please, do see a message and a link for students below) and we will be happy to provide you with the data/result/report for your institution.

Please, do not hesitate to contact me in case of any further queries.

Essentially, we have various HCC cell lines that we plan to do a migration assay using corning transwell 8.0 um pores w/ matrigel. Utilized a chemoattractant of 5% FBS/DMEM serum as the chemoattractant. Utilized some growth factor + inhibitor that was present in other wells for variation. We seeded 50,000 cells and they were visible in the insert following seeding. However, when I washed/scrubbed the insert following fixation (4% PFA, then 1% crystal violet soln). The issue comes when I observed the cell/inserts under the microscope for imaging. I noticed that there were only cells present around the edges of the insert..My assumption is during the scrubbing with the cotton swab, the cells were removed. In this assumption, I would then assume that the cells never migrated down through the pores. For the chemoattractant with the growth factor, we used a concentration of 50 ug/mL and on the last variable, we used an inhibitor following that pathway with a concentration of 1.0 uM. The cells were allowed to migrate for ~24 hrs. I suppose, we could increase invasion time to 36 hrs to see if that works, but not sure what else to troubleshoot, as scrubbing is necessary to remove non-invaded cells..

Thanks in advance for the assistance.

Hello everyone,

I was performing migration assays using wound healing and transwells. I had different results in both analysis. Actually, with transwells I got significant results but by wound healing assays there is no difference between control and experimental. Is it possible to have these results?

I have read about different types of migration (collective and individual) but I do not really understand it.

Could someone tell me how these types of migrations work? and how is it measured by different assays?

Thank you in advance :)

Usually, sample buffer comprises 10% SDS, however, if it is reduced to 4-5%, does it affect the protein migration in gel?

I have timelapses of migrating cells and want to analyze the behavior of the the cell processes, (like extension and retraction) as well as look at their length and branching etc. What software could I used best to do that? Any automated software available?

cloud computing

Can the crosslinking of preoteins, intra or intermolecular, change the electrophoretic migration behaviour of proteins on SDS-PAGE so extraordinarily, that they migrate much lower then estimated? how to explain? higher globularity of crosslinked proteins ?

The concept of immobility is showing up -- and often in relation to the closures that the pandemic has created. My concern or interest is in the way immobility is used. Often it seems posited as the opposite of mobility (or in other words NOT migration) and that is rather narrow. Immobility is also used to describe the limits on peoples who would otherwise cross national/international borders. Shouldn't internal movement factor into our discussion as an alternative? And immobility is more than not migration, would be interested to hear thoughts on this.

I'm working on a Research focused on this theme and I would be grateful if some of you can share his/her knowledge about the topic. Any input is appreciated, thank you.

Aim of qualitative research study is to elucidate the migratory push factors determining locally born and educated registered nurses to migrate from the only tertiary level hospital located in the small island, modern metropolitan capital city. in a country maintaining fairly stable economic and political conditions..

Undoubtedly, in consideration of globalization, an escalation in the number of native RNs migrating from a ''destination nation' for nursing migration, has grabbed the attention of healthcare systems stakeholders in the midst of the COVID-19 pandemic, there is no empirical evidence available to provide answers toward the planning and implementation of policies and strategies to stem the flow of these limited human healthcare resources' out of the nation's public healthcare system.

Can anyone help me to formulate my research question for a thesis paper? I would like to do a research regarding the influence of sustainable development agenda 2030 on migration flows and human rights. Yet I also want to include in my research the fact, that not only safe and regular migration can help to achieve sustainable development, but the agenda 2030 can also have a positive impact on regular migration and human rights security (may be with a reference to gender issues or climate refugees).

I will be grateful of you could help me out!

Thank you!

What migration has to do with it?

What do you think is the general framework for analysing migration? What are the goals and objectives of this analysis? How are migration patterns best categorized? What is the practical application of migration models?

I'm looking for a questionnaire or survey the focuses on "reason for migration". I know there are questionnaires that include "reason for migration" items, but they tend to be focused on acculturation or some form of trauma.

Hello. I am looking for a good choroidal endothelial cell line to

I am interested in research migration to Poland and would be happy to read.

Is there any centralized database that would list and preferably also shown on a map all Eurasian and African archaeological sites from years 5000 - 1500 BCE? I would need to see, whether the appearance of archaeological sites correlates with the appearance of ancient place names.

Our team studied the geographic distribution of 15 ancient name sets to see, where they appear as place names and personal names. We found out that most of the ancient name sets seem to have their urheimat in India (e.g. Phoenician, Hyksos, Mitanni, Berber, Sea Peoples and Ethiopian) or have a very strong connection with India. The second highest density of ancient names was found in the river valleys of Volta and Niger in Africa, with relatively high density also along Danube and at the western parts of Eufrat & Tigris.

A short summary of the study is available here:

I am studying the annealing effects on double perovskites. As we all know, annealing shows some significant effects on decreasing defects and increasing grain boundary, etc. However, ion migration is always a daunting problem towards the stability issue of perovskites, which can be aggravated with high temperature and open-air environment. There are some references mentioned mechanical degradation issues under air environment. I am wondering if annealing under open-air is a double-edged sword. It may improve the crystal ability or degrade the sample due to ion immigration. Thanks in advance!

Have controlled migration of plants (various species of trees with a selective chosen genetic origin) can be a way to stabilize the forests of economic use and provide a fully renewable source of wood raw material? I recently watched the movie “Breaking Boundaries: The Science of Our Planet”, which organizes a lot of information about our Earth (official trailer - https://www.youtube.com/watch?v=Gb6wQtNjblk). Breaking Boundaries tells the story of the most important scientific discovery of our time - that humanity has pushed Earth beyond the boundaries that have kept Earth stable for 10,000 years, since the dawn of civilization. The forests are one of the systems that regulate the state of the planet. If deforestation goes above 25% of the world’s forest cover (we broke this estimated border), with global warming increasing, we are likely to experience an irreversible process of savannization and desertification. Can we help forests by accelerating the controlled migration of trees adapting them to climate change, without forgetting the role of the economic forest and biodiversity? Is our knowledge sufficient to effectively do it? What do you think about it? Is it worth intensifying research from this scope?

What is your opinion regarding these issues?

Some legal philosophical approaches to these questions can be found in my paper "Extreme Wrong Committed by National and Supranational Inactivity: Analyzing the Mediterranean Migrant Crisis and Climate Change from a Legal Philosophical Perspective", Göttingen 2021.

I am still in the early stages of this, however I am thinking of exploring the potential football has, as a means to aid the integration of Venezuelan refugees in countries like Peru and Columbia. I am reading that similar to Europe, refugees are subject to racism and resentment. While also in Europe, football clubs have started to partner up refugee forums to help. UEFA recently wrote a report of their commitment to helping the cause. I also wonder if CONEBOL could implement the same action. Early indictors suggest their is a gap in the literature, when it comes to refugees and football in South America.

Hello,

we are running sds-page electrophoresis gel of two purified protein. Both proteins have the same theoretical size but in the gels they migrated differently. Both have different Pi, one is 6 and the other one is 7. Do you think that this could affect the migration?

Thanks.

What kind of relationship can be found between the governance of processes of migrants´ integration and local/regional governance of shrinking towns? Can migration and shrinking areas (regions) be a "happy couple"? What is the role of governance in for integrating migrants in shrinking areas in Europe? What mode of governance suits better? What are your thoughts and state-of-the-art litterature to tackle these questions?

In your opinion, governance is a solid theoretical framework that stands by itself?

I want to start a new research on the flows of migrants from the Middle East to Europe and I am thinking of using the gravity model to analyze it. Gravity models are frequently used in the analysis of foreign trade flows.

I am trying to relate Climate issues with migration and gender marginilization. I am wondering if there are any technical calculations or index that has been used before to quantify or measure the impact - the parameter may be economic, or any other. Depending on how it can be quantified, I would shape my research.

I am open to ideas

What is the best scale to measure intention to leave the country? Is it a good idea to adapt some of the intention to leave the company scale?

Does some gene mutation that increase migration necessarily increase invasion?Is it possible that some mutation that enhance cell migration but inhibit its invasion?

Apart from the DSAS tool, in GIS what are the other options available for mapping and analyzing the shoreline migrations patterns over a long time period?

The value of migration period i.e. "p" has been set to 5/12. Is there any specific reason behind the same? Why can't we use the migration period as 7/12 when the butterflies are in Land2 for 7months and in Land1 for 5 months. Or is there any other value that we need to take according to our problem statement? How can we decide this?

Same is the case with BAR value and maximum step value.

In connection with the warming of the Earth's climate, progressive global warming, some areas located in the sub-tropical zone in the future will not be fit for existence, and the migration processes of the population will be intensified.

Do you agree with my opinion?

Please reply

Best wishes

Hello

I plasma(H2N2) treated Al2O3 plate (edge is connected to ground) and wondered if oxygen vacancy migration on the plate can occurs as electrons escape through edge.

Or whatever positive charge migration.

thank you

It is requires for a research work.

How do you evaluate the European Union's position on Refugees? Is the EU fair enough? Can irregular migration be prevented?

Since last year the work from home and e-learning environment have proved to be some of the efficient ways of communication. The recent covid crisis has resulted in economic hardship for people of all ages. People are looking for opportunities of cost cutting. Migration from large metropolis is one of the recent moves observed in large cities like New York, San Francisco, Los Angeles, where people are moving to the areas in Idaho, Indiana and Oklahoma to minimize the cost of living including rent and mortgage. Is this trend observed worldwide?
