How do you use your favorite and delightful fireplaces today? Firewood and coal are prohibited types of fuels

A court sentenced to restriction of freedom of a man who burned wood and coal in the oven for heating.
He violated the resolution against smog. More

This story happened in Krakow in Poland in November 2019.
Who invented such atrocities?

Why did you block me and don’t want to help me? Why did Twitter turn off 2-step verification of my account? This was done precisely by Twitter, because I change phone numbers and companies, but the code does not come.

Goodbye, Academy!

You often ask me: "Why do not you want to work in an academic environment at the university of some country?"

I answer: "It's true." I really do not want this."

I do not take judging about the scope of scientific knowledge from which I am far. However, what they (academic science) write in their articles about my whole area of the mineral processing, this is a complete nightmare and ignorance. I read the articles in different languages and I am horrified. These "scientists" do not even understand what they write. Most of them simply rewrite other mistakes and misconceptions. This is not science. If there are guides, then the processing of minerals is in a steep peak. The poor Earth Climate will not take away this ignorance. 
 This is not my way.

Academic community seeks to score each scientist a label of the country, scientific school or university: "If a scientist  reached any scientific heights, this is not his merit, but it means that his country (which of them?) is such a "great" and "wise" (scientific school or university too). This is not discussed! In their opinion, the personal merit of the scientist does not exist without THE MERIT OF THE UNIVERSITY. So the delegations go to establish academic exchanges. Agreements on intent are signed. They appoint official "teachers" and "disciples" of this scientific genius, so that these official "teachers" and "disciples" sign any fraudulent contracts and projects without reading. The lie is multiplied.
But I do not want to participate in this lie! 

I do not have any teachers or disciples! I was taught only on basics of sciences as well as thousands of others students. I reached my wisdom by self-knowledge! And I did not give to anyone the depth of my knowledge, I did not teach anyone. Everyone who calls himself as my disciple (or teacher) - is the IMPOSTER. 
We are cosmopolitans! 
We work for all of humanity, not for a country or a university. We are working independently for many years.   We are in us self. Do not associate us with some country, scientific school or university!
They do not own our knowledge; they do not have the authorship in our inventions and our know-how. Several countries and universities try to attribute our merit to its self. But they do not have anything, except their positions and rights of the signature in their  university and their country.
We are not serfs! We do not belong to them as the results of our work too!  
They can not create anything  really working, but only counterfeit and only on paper.

The role of personality in science is strongly underestimated. This is one of the distributed mistakes of our time.

I'm reading the academic scientific articles, I see that they contain a huge number of errors and deception. I do the comments, but they persistently rewrite the lie from each other and a lie is multiplying.
I feel myself as "Gelsomino in the country of liars".

We try to follow principles of  Real Scientist, one of which is NOT TO PARTICIPATE IN THE LIE. 

I do not want to participate in Lie! Therefore, I do not want to work in an academic environment.
I'm an independent scientist!

The turtle can overtake the hare

How did they want to measure bubbles with a diameter of 10-12м, if the device (Cillas 1064 laser particle size analyzer) has a resolution only in the range from 4 x 10-8 to 5 x 10-4м? Where are the picobubbles? Well, at least nanobubbles? Not!

Picobubbles cannot exist even theoretically!!! This is complete nonsense!!! More
 At the very beginning of the study, they found that the smallest particles have the highest ash content. In fact, particles less than 0.5 mm are ash. Why didn’t they stop researching and continue to float them? What is the purpose of extracting ash into concentrate?

They write that the bubbles are small bubbles have a low rate of rise, but the flotation rate increased by 200%. How is this possible?  The turtle can overtake the hare.
Daniel Tao, Rick Honaker (University of Kentucky) wroted "Improving Coal Flotation Recovery Using Cavitation Concepts (KY007) More: "Picobubbles (usually less than 1 micron) selectively attach to the hydrophobic coal particles...
The picobubbles should be 10-12м, but 1 micron is 10-6м.
This is as how to compare one million dollars and one dollar.

.... Preliminary results indicate that the flotation rate of -100 mesh Coalberg coal can be increased by at least 200% by using an air eductor to pretreat the feed with submicron bubbles.
 They are characterized by an inherently high probability of collision with particles and high probability of attachment and low probability of detachment due to their tiny size,
low ascending velocity and rebound velocity from the surface, and high surface free energy to be satisfied, and therefore are very effective for enhancing flotation recovery of fine and coarse particles..."

Why did they examine the charge of the bubble and not the effect of the size of the bubble?

K.E.Waters, HadlerJ.J, Cilliers (Froth and Foam Research Group, Department of Earth Science and Engineering, Royal School of Mines, Imperial College London, SW7 2AZ London, United Kingdom) wrote "The flotation of fine particles using charged microbubbles": "One of the major problems in the flotation of fine particles is the decreased probability of collision between particles and bubbles, which can be improved by a reduction in bubble size."

I replied: "This is not entirely true.
Small hydrophilic and hydrophobic particles can very successfully float on the surface of the water (the surface of the water is a giant bubble.
The title of the article does not correspond with its content.
Why did they examine the charge of the bubble and not the effect of the size of the bubble? "

The effect of nanobubbles on flotation is not straightforward

A.Azevedo, H.Oliveira, J.Rubio (Laboratório de Tecnologia Mineral e Ambiental (LTM), Departamento de Engenharia de Minas, PPGE3M, Universidade Federal do Rio Grande do Sul, Brazil) wrote in an article "Bulk nanobubbles in the mineral and environmental areas: Updating research and applications":
"These nanometric bubbles present interesting and peculiar properties such as high surface area per volume unit, high stability and longevity, surface charge in water and the ability to aggregate hydrophobic particles." More

I answered: "This is not entirely true.
 Bubbles of any size have a surface charge in water and the ability to aggregate hydrophobic particles, but not only nanobubbles. Even on the surface of the water.
The effect of nanobubbles on flotation is not straightforward. In ordinary flotation, nanobubbles cannot meet particles, since they cannot overcome hydraulic flows and the energy barrier. During the flotation, they are formed nonselectively on all particles (on hydrophobic and hydrophilic particles).

I do not want to participate in lie. Therefore, I do not want to work in an academic environment

You often ask me: "Why do not you want to work in an academic environment at the university of some country?"

I answer: "It's true." I really do not want this.
I'm reading the academic scientific articles, I see that they contain a huge number of errors, deception. They persistently rewrite the lie from each other and a lie is multiplying.

I do not want to participate in lie. Therefore, I do not want to work in an academic environment.
I'm an independent scientist!"

P.S.  A fragment of our article "WHY ARE WE DOING PERSONAL RESEARCH?"

if we turn to the fountainhead with the question "What is a true scientist?" then we will see such signs of a real scientist, they are well known from classical philosophy:
 
A sincere desire to comprehend the truth (Without substituting the goals of cognition for a career, status, etc. Without this one point, there is no scientist);
Non-conformism (Independence from other people's opinions, from "likes", fashion trends);
Cosmopolitanism (Independence from the interests of a country, religious or national group, region, university, research institute, department, scientific school, etc.);
High competence in their field. Wide scientific interests (Ability to independently learn the truth, that is, to solve key problems and draw conclusions at the interfaces between sciences. The ability to prove the correctness of their judgments by rigorous calculations for himself, not by voting);
Openness of knowledge (Ability to openly and in a clear language to share acquired knowledge with the whole world, transfer his own knowledge to other areas, and not hide knowledge in "closed" journals);
High responsibility (Ability to be fully personally responsible for the results);
High morality (The desire to increase good in the world, not to increase evil, not to participate in lies);
Self-restraint (The desire to avoid excesses).
We ourselves sincerely try to adhere to these principles, and this inevitably led us from the university to the independent science.

It doesn’t surprise me that a "Canadian Process Technologies Inc" is writing fairy tales about flotation. This is not their first bad story. I was surprised that Russian scientists from Irkutsk National Research Technical University believe in these tales and even get patents for them!

Bubbles do not make the surface hydrophobic.

Picobubbles cannot exist even theoretically!!! This is complete nonsense!!!
The approximate diameter of the molecules is (2-3) x 10-10м. 
Picobubbles is 10-12м?
How can an air bubble be smaller than the molecule of which it consists? 
Complete nonsense!

Why do scientists contradict themselves and the theory of flotation?

V.I. Melik-Gaykazyan, D.V. Dolzhenkov, N.P. Emelyanova, M.I. Trufanov, T.I. Yushina (Moscow Mining Institute, National University of Science and Technology «MISiS», Russia) wrote an article "NANOBUBBLES AND THE MECHANISM OF THEIR PHENOMENAL FLOTACTIVITY AND SELECTIVITY OF ACTION"- They took photos. The photographs show that the contact angle don't depends on the size of the bubbles. This is consistent with flotation theory.

They are aware of this and demonstrate a classic drawing on page 19 [2].
Why did a scientist draw dubious conclusions that contradict the theory of flotation?

They wrote in their article: "1. The reason for the high flotation activity of nanobubbles is their ability to instantly spread over the surface of the particles due to the high capillary pressure in them.
 2.  On the perimeter of the spreading nanobubble, transport” bubbles formed as a result of coalescence of microbubbles can easily be fixed. They float particles."

I answered: "I think they made false conclusions.
1. Bubbles stick to the HYDROPHOBIC SURFACE and in accordance with the 2nd law of thermodynamics.  
Probability of meeting the nanobubble and particles are very small, therefore, the effect of nanobubbles on flotation by this interaction mechanism is negligible (the nanobubble has an insignificant kinetic energy).

2. Coalescence of nanobubbles with each other is an unlikely thermodynamic process."

In connection with the unhealthy interest and aggressive hunting of a number of countries and large companies to my science-intensive products, there is no a privacy of my correspondence in e-mail and social networks.

Almost all of my accounts on social networks have been hacked from October 26, 2019 to the present day (and earlier this also happened many times).
But not only that.
For example, today, within 10 minutes, someone hacked my mobile Wi-Fi Internet access point again and connected 55 devices to it! This happens already at least the fifth time in a month with the regular change of my complex password. This could only happen here on the spot. After all, Wi-Fi has a very small range (tens of meters). Who can crack the hardest password in a few minutes?

I suspect that strangers have access to my social accounts and my husband´s too. Do not believe the "likes" and other activity coming from our social accounts! Recheck the information in another way!
Why aren’t Linkdin, Twitter and Gmail taking steps to identify violators and restore the security and full functionality of our accounts?

GENIUS vs. UNIVERSITY

You send me many letters asking me to write my business plan. It is right that you are interested in my opinion. I worked in different universities of the world. I communicate a lot online with different people.

I can share my independent opinion about mining in the world. Everywhere is the same. They promise to do this work and go to the laboratory to do experiments. Next on luck. It turns out or not. 

There is no laboratory in the world has enough equipment and specialists to create new generation technologies. Problems are growing. Traditional types of ores are running out but for new ores there is no technology.

I did a little calculation. How much money is needed to create a modest modern ore benefication laboratory.
1. Buildings and facilities – 20 million dollars
2. Equipment and apparatus – 15 million dollars
3. Monthly expenses are more than 15-20 million dollars per month.

At full load, this laboratory and design organization can perform work for a maximum of 2-3 million dollars per month. This whole company of specialists from around the world will be able to perform work only in a close-knit team: because each of them knows only his own problem and does not control the whole situation in the complex.

This means that every month you lose 18-12 million dollars per month (216-144 million dollars a year). You also spent another 35 million on equipment and building. Also You have to spend several million on staff training.

Let’s say that you went the traditional way. You invested hundreds of billions of dollars (for 50-100 years). You have trained hundreds of new specialists, opened new research institutes and laboratories, and issued hundreds of scientific grants. And so, 50-100 years passed, but a miracle did not happen. If you have not yet done this, then stop, and do nothing.

Universities understand that they have no such opportunities, but they really want the money. They create a fairy tale for investors on paper. Next to the sign that this is a student’s educational laboratory of ore beneficiation, new ones will appear: Innovation Center, Technology Center, Technology Certification Center, Certification Center of raw materials (ore, waste), Center for complex processing of raw materials, Laboratory for waste processing and so on.

If earlier it was a backward laboratory with old non-working equipment measuring 100 square meters, now, according to documents, this is a certified scientific center measuring 200-600 square meters and with the latest stunning equipment worth millions dollars.

They enter into their documents famous people who do not even know it. I learned many times that someone enrolled me in my project or scientific school without my consent and permission.

They draw up the necessary documents and begin to search for the simpleton. However, they have no idea what they will do.

I know many such examples. If a researcher can just “eat money” for years without getting the expected final result, then he will do so (Murphy’s Law). The increase in funding for research will only exacerbate this situation.


I suggest that you bypass the path of traditional development.

I considered the costs and did not create a laboratory. I created “PETROVSKY´S MATRIX”.
For many years I have been working on creating a “Mineral Benefication Information System”. I create it with my own money and am the only copyright holder.

This system you need. I don’t need it.

I can create 5 competing technologies for any ore without any information system. It is very difficult and only I can do it. In fact, “Mineral Benefication Information System” will be my only competitor.

You need my “Mineral Benefication Information System” and “Petrovsky’s Matrix”.

No need to teach anyone. For this, you will need centuries of hard work and the abandonment of all your stereotypes, theories and delusions. I think that for you it is almost impossible in the near future.

You need just to create a my smart system and let it work.

You do not need hundreds of specialists in the field of mining, but only a few people to interact with the expert system”Mineral Benefication Information System”. An independent expert system will describe the real situation (only if it is correctly taught) and will give you the accurate way of solving the problem.

Therefore, if we are talking about relatively small investments (about USD 10-20 millions), then I can recommend you to invest in me, this is the most reliable investment.
So, my business plan is an investment in me and under my name. Then we decide what is best for you, we can determine in detail the larger investments (under USD 1 billion and more).


You choose.

This is a completely different mechanism of action

Researchers of University of Rochester in New York wrote "These grooves made the surface superhydrophobic by allowing it to capture air and repel water." 
IT IS NOT TRUE!!! 
They must treat the surface with a water repellent to make the surface hydrophobic, but they did not.

This is a completely different mechanism of action.
This is other physical phenomenon that allows a completely hydrophiliic surface to have air bubbles. (For example, glass. Its contact angle is 0-10 degrees. This is the limit).


P.S.  My thoughts on the article "Researchers have developed "Highly Floatable Superhydrophobic Metallic Assembly for Aquatic Applications" More

Why do you believe? You do not have enough knowledge to question the words of scientists

If someone tells you that the fish swims due to micro bubbles on its surface, you will laugh. No, the fish swims because it has a swimming bladder. Why do you believe so easily that micro-bubbles will help lift submarines? 
Because the article has key phishing words that increase your confidence in what is written: scientists, researchers, innovation, unsinkable ships and emergency floatation devices...
Why do you believe? You do not have enough knowledge to question the words of scientists.

Believe it, it’s the same as believing that Baron Münchhausen pulled himself out of the swamp by the hair.

These researchers are engaged in nanotechnology and their research has a narrow specific application

One asked me: "Researchers have developed "Highly Floatable Superhydrophobic Metallic Assembly for Aquatic Applications"
They claim that  There’s potential for unsinkable boats, puncture-proof life jackets....This could be a real chance the researchers write, to innovate “conventional floating devices and watercrafts that have been used for millennia." More
 What do you think about it?"

I answered him: "I think this is not true. These researchers are engaged in nanotechnology and their research has a narrow specific application. 
They applied capillary force in the opposite direction. It matters with a very small distance between the plates (figure b, c, d). 
When the distances are large enough, the capillary effect will disappear and other physical quantities will prevail. (figure a)"
