Contracts - Science topic

Well, I was trying to predict how much energy a pneumatic system would need in order to actuate in a specific force and speed, but it seems that I would need too little energy for too much work.

I was aiming at 3000kg and contraction lengths of around 5 to 10 cm with actuation speeds around 0.2 seconds. So, I was wondering how I would go on about making a pneumatic system with artificial muscles, they would essentially work like an horizontal pneumatic cylinder pushing against two ropes, simulating a contraction, but I don't know if I'm correct.

(first picture)

Using an online Hydraulic Cylinder Calculator: 600 lpm for a 50cm² area cylinder with 80 mm of diameter and 300mm of stroke. at 0.1 bar = 5kg of force 3000 kg target / 5 kg = 600 600 LPM x 600 actuators = 360,000 360,000 x 82 actuators = 29,520,000 LPM

I found a data sheet of an 80cm wide industrial ducted fan that produces 400,000 liters per minute of airflow and 560 pascals of pressure at 3.3 kilowatts.

(second picture)

29,520,000 lpm / 400,000 lpm = 73.8 73.8 x 3.3 kilowatts = 243.54 kilowatts = 324.72 horsepower. Since 0.1 bar = 10,000 pascals 10,000 / 560 = 17.8571428571 x 324.72 = 5,798.57 hp in total

(third picture)

If you take the fact that ropes suffer 5 times more tensil strength around 170º degrees of angle, then you would need 5 times more energy: 5,798.57 x 5 = 28,992.8 But if I use a torque and rpm calculator, where these fluidic muscles would be attached to, they would basically output around 10000 nm of torque with almost 300 rpm of speed. And these would result in a 300 kilowatt motor. 300 kw per actuator x 82 actuators in total = 24,600 kilowatts = 32,800 horsepower. Obviously, both values would be different anyway due to differences and inefficiencies, but the pneumatic one should at least be slightly higher than the second equation; An actuator that requires less horsepower to rotate a mechanical arm with 400 horsepower seems to break the laws of physics to me, but I don't know what I did wrong... Maybe this is due to differences in the laws of physics being used? One is about fluid physics, for example... But… Even if you don’t have the cable into consideration. It would still be just 5,798 horsepower… I put these values to a kinetic energy calculator and it calculated it would output around 6000 joules of energy. And since joule second = watt second...

The Techniques that are used when tendering for a contract within the United Kingdom, and how a Project Manager manages the commercial and contract matters of large complex projects.

Is Academica Press (https://www.academicapress.com/) a legit (not vanity or predatory) publisher? Is it any better than Nova?

What makes me suspicious is that their email ends with 'gmail' and they -- unlike Nova -- did not send a contract to sign but only asked for a full manuscript.

It might be that I got a spam email with the same name as A.P.

Thanks

Interference between two levels occurs through this contraction that occurs to space-time, and therefore, if we assume that the electron is in the third level, such as the sodium atom, and according to de Broglie’s law, the third level needs 3 ripples, so if a contraction occurs from the higher level until it interferes with the electron level, such as level 4 It is in the form of 3 ripples, and if there is interference from level 6 with the electron level, which is in level 3, it occurs in the form of 3 ripples, but the difference is that level 6 is the ripple amplitude (vibration amplitude) is higher than level 4.

If we delay the arrival time of one of the two quantum entangled electrons from the monitoring screen, what will happen is that normally the two electrons must coincide (the arrival of the two electrons) at the same time to the monitoring screen. But what happened is that we delayed one of the two electrons, so what will happen is that it will happen, a contraction in the fabric of space-time so that the distance between the two electrons is equal. Therefore, the lagging electron passes through the contracting fabric of space-time between it and the monitoring screen, so that the distance between the two electrons is equal when they are observed. But because of that contraction, the delayed electron exceeds the speed of light and is quantum entangled with the other electron. Therefore, it will be in the past, and this indicates that if the electron is detected, it will affect the results of the experiment.

Hello everyone. I have a question related to registration for the CSIC job bank. My situation is the following. I registered and I have already appeared on the list of merits but they have given me a bad evaluation and therefore I have made an objection. They told me that it usually takes between 1 and 3 months so I must continue and start the contract for which I signed up. Has anyone been in this situation of waiting for the resolution of an objection when they are already working? If the objection is successful, can the status of the contract be changed even if it has already started?

Thank you!

Good morning, does anyone have a contract to publish with MDPI?

I founde some textbooks stating that typical skeletal muscles can shorten up to 70% (optimally up to 30%) during contraction. However, I would like to look at muscles per region.

This might seem like a very unrealistically simple question, as there are many factors which determine the shortening of muscles during contraction, but I would like to create general reference values for modelling purposes.

Any advice on where to look or how to even measure this would be great!

The aim of this study is to investigate the contemporary worthiness of investing in a college/university degree amidst the emergence of Large Language Models (LLMs) and Generative AI (Gen AI), the challenges of job scarcity, and the prevalence of contract cheating in education.

In the following paper;

considering

a) the experimentally verified two-way SOL = c to very high accuracy [1],[2],[3],[4]

finding the light times in a configuration of train and embankment with

b) the experimentally verified twin effect, to second order approx in v/c [6],[7],[8],

c) the Sagnac effect, verified to first order approximation in v/c [5]

the result is that the SOL in the embankment is L/c

while the SOL in the train is gamma*L/c, at variance with a)

Since a) must be complied, the Sagnac effect in longitudinal motion, an experimental evidence with a lower accuracy must be ameneded by assuming the Length contraction of the train as REAL.

THis means that Length contraction cannot be niether reciprocal nor symmetrical. That involves the existance of a preferred frame in which it is clear what is the non-accelerated system which moves more or moves less once the isotropy of SOL of one system is assumed considering what has been accelerated from where.

I submitted a Project Pitch to the NSF and I got approved and invited to submit a full proposal, how do I find researchers to contract?

It is for a novel heat engine so I will need someone with fluids and thermodynamics experience.

Mostly with ORC and refrigerants experience.

I am excited as my project pitch was approved in less than 4 days so that gives me some degree of optimism.

Any comments are welcome.

It is generally believed that time dilation and length contraction is a geometric effect, is there anyone has tried to explain the time dilation and length contraction effect in a geometric way?

Albert Einstein is said to explain the time inflation effect in this way:

"When you sit with a nice girl for two hours you think it’s only a minute, but when you sit on a hot stove for a minute you think it’s two hours. That’s relativity."

Abstract

Using a unique hand-collected dataset of purchase obligations, we find that customers’ financial reporting quality is positively associated with future supply contracts, indicating that suppliers are more willing to contract with customers who provide them with better information. Further, the association between customers’ financial reporting quality and future supply contracts is stronger for customers with strong bargaining power, which is consistent with suppliers relying more on financial reports when they have less access to customers’ private information. Collectively, our results suggest that customers’ financial reporting quality plays an important role in influencing suppliers’ decisions to contract with customers for the future supply of goods and services.

Good morning everyone,

I'm conducting some trials with sEMG located on peroneal muscles: subjects are making a drop jump and a re-jump immediately after landing on the same leg.

I haven't got a force plate to detect ground contact or other devices: I can rely only on EMG data.

When can I consider activated and at rest the peroneal mucles during the task?

This is important to me to detect the curve of the muscle activation between subjects in a standard manner.

I was thinking about choosing for example a 10% threshold relative to the Maximun Volontary Contraction.

Do you have some ideas or some research papers with suggestions about this?

Thanks a lot!

This question delves into the complexities of assigning liability in the context of smart contracts, self-executing agreements built on blockchain technology. Determining who bears the legal responsibility when a smart contract doesn't fulfill its intended function as programmed. The smart contracts can contain code errors, bugs and vulnerabilities. There can be unforeseen circumstances, unexpected events or data when running the code. The code's programming might affect the contract's execution and subsequent legal considerations. Finding who is liable can be challenging due to the absence of a central authority figure involved in its execution.

The way in which the contractual dispute was formed was that the fixed obligations of one party made it an economic force of the contract that could not be resisted, while the immutability of these obligations made the other party something rigid. This constitutes “a fundamental loophole in the contract, to prevent the fragmentation of the contract’s economy.”

Technology poses new challenges for the legal system. This question delves into the legal framework surrounding smart contracts. Some points to consider are contract law principles (e.g., intent, good faith, established rules for interpreting written agreements), code versus natural language, judges may require technology experts to understand the code, jurisdictional differences, adopting specific contract laws, and relying on existing frameworks, adapting to the rapidly evolving technology of smart contracts, dispute resolution mechanisms. Concerns that could arise from potential ambiguities are related to code bugs, unforeseen errors, unclear language, poorly written functions, external dependencies, oracles, and what else?

The civil legislator stipulates that disposal of real estate outside the real estate registration department is considered invalid. However, many people conclude real estate sale agreements outside the real estate registration department, and include a penalty clause that the party abandoning the agreement must pay to the other party. What is the legal value of this penalty clause? Is it possible to go to court to demand it from the defendant?

Smart contracts, self-executing agreements on the blockchain, hold the promise of revolutionizing everything from supply chains to financial transactions. But what happens when things go wrong? Can this "code as law" be enforced in a traditional court of law? Are smart contracts legally binding?

It is known that to explain the results of the experiments to detect the ether drift made at the end of XIX century FitzGerald and Lorentz suggested that some parts of the devices oriented along (possible) motion of the ether should contract. Both FitzGerald and Lorentz couldn't give physical explanation of their idea.

The excellent explanation of the null results of these experiments was given by the special relativity.

But despite the excellent explanation, one point was unclear - if this contraction of the bodies is physical effect. Thus, (from Wikipedia)

In 1911 Vladimir Varićak asserted that one sees the length contraction in an objective way, according to Lorentz, while it is "only an apparent, subjective phenomenon, caused by the manner of our clock-regulation and length-measurement", according to Einstein.

So now the dominant concept is the the contraction of the moving bodies is a 'seeming, apparent effect' and it is cause by impossibility to measure the lengths of the moving bodies in the right way when the observer is at rest.

However, if we take into account original treatment of the null results of the Michelson-Morley experiments, a question arises. In these experiments, the measurements of the moving bodies had not been made. It was necessary to explain the equality of the travel times of the light beams along the arms of the device. So it unambiguously follows from the equality of the travel times that one arm of the interferometers must contract. Therefore the contraction must be the real physical effect.

So, my question: what is a physical meaning of this relativistic contraction?

I give some simple calculations in the attached file to explain why this effect should be physical.

Liability for incidental losses - a type of business loss or during the course of a contract.

The question challenges us to think creatively about how to leverage emerging technologies while navigating legal and commercial considerations to maximize the potential of smart contracts in the real world. The factors to consider are standardization, oracles, decentralized identifiers, smart legal contracts, privacy-preserving technologies (zero-knowledge proofs, homomorphic encryption), regulatory compliance, etc.

According to the contractor’s mistake - because he committed a crime beginning or during the implementation of his contractual obligation (“contract validity”).

This (starting with submitting forged documents, using fraudulent means or methods, to conclude a contract, impersonating a person, etc., or giving false information that amounts to a crime).

And (during the implementation of the contract - intentionally causing damage by committing a crime during the validity of the contract, such as theft, embezzlement, revealing the secrets of contract implementation, revealing designs, or tampering with them, which constitutes a crime punishable by the Penal Code).

Our study consists in noting the progressive apprehension in Iraq and French positive civil law of environmental legislation. The purpose of this study is to demonstrate that there is a functional and interactive relationship between civil law and current environmental concerns. These help to modify Iraqi civil law and force a rethinking of a number of its fundamental principles. When interacting with civil law, environmental concerns will primarily affect contract law. Finally, regarding contract law, environmental concerns affect the general theory by increasing the compulsory content of the contract and the content of named contracts. The environment is also becoming a fully-fledged object of new contracts which have as a direct or secondary purpose the protection of the environment. All the changes thus observed foreshadow a specific legal space, private and public, whose object is the environment and its protection. In view of these concerns, it is possible to wonder how the environment and the contract can really meet, consider each other and more broadly influence each other since, in fact, the environment is part of a long-term perspective. It is developing for current generations but also for future generations. As some authors argue, environmental law is intended to govern a general interest, whereas the contract is the tool par excellence for governing particular interests. But are general interest and particular interests diametrically opposed? Why can't the contract serve the environment? Of course, environmental law has its own instruments, such as impact studies or environmental responsibility, but doesn't this law deserve efficiency from all .

I am doing research on analyzing what factors affect lumpsum contracts. qualitative analysis using risk breakdown structure and quantitative analysis using analytical hierarcy process. i want to know what steps i need to do.

The question asks if new laws or regulations are necessary to govern smart contracts that utilize such emerging technologies as AI, large language models, quantum computing, voice user interfaces, IoT, etc. Essentially, we are exploring the regulatory landscape surrounding smart contracts, particularly those incorporating new and innovative tech.

Contractual solidarity is a familiar title and traditionally seems to be a stable and stable system. Still, the meditator finds that it raises critical legal problems, whether it is the harmonization between it and the general rules of the contract or the obligation to cooperate information and security, as a point of balance between the conflicting interests of contractors. It leads to the emergence of personal rights that guarantee the legal protection of the contract, which allows the legislator and the judge to intervene to ensure the effectiveness of its judgments? How can each party to the contractual relationship satisfy the legitimate expectations of the other party without harming the other party? Which means that everyone owes the other and owes society under the idea of solidarity? The analytical study of this subject in this research is a serious attempt to answer these questions. The parties' selfish interests before the contract's conclusion cease and disappear upon the execution of the agreement, through the dependence of the parties on each other for their common interests, the so-called contractual solidarity. The idea of solidarity is not the result of the moment. Still, its emergence has extended to varying periods, and on this basis, this research will be divided into two topics that address the concept of contractual solidarity. In the second, we will explain how solidarity and contract are compatible.

The question is about the legal landscape surrounding a relatively new technology. How can existing legal frameworks, designed for traditional paper contracts, adapt to the automated and self-executing nature of smart contracts? This includes questions about contract formation, validity, interpretation, and enforcement in the context of blockchain technology. How do existing laws in different jurisdictions (e.g., contract law, consumer protection, securities regulations) interact with smart contracts? This can vary depending on the type of smart contract, the assets involved, and the parties' geographical location.

What are the legal challenges and opportunities associated with developing and deploying smart contracts that leverage emerging technologies?

We know that the universe is expanding with acceleration. Can there be any event of such a large scale that can alter the trend of expansion and begin contraction or even stagnant universe?? Lets discuss

From our perspectives, we observe that the Universe is expanding; the galaxies are moving farther away from us; they are being red-shifted. But it might be possible, that the Universe is not actually expanding, it's contracting towards the very same singularity it took place almost 13.8 billion years ago. This would eventually create another Universe. That's exactly what is accelerating our universe's expansion; the dark energy is nothing but the force of the singularity, where all the mass of the whole Universe lies. And this contraction would not be just 3 dimensional; it is happening in the 4th dimension; universe is expanding to it's past singularity (contraction). Just thougts.

We have sheared numerous loose samples of sandy soils in undrained TXC conditions. A common behavior observed herein was dilatancy in stress paths at the first stages of shearing.

Normally, it's expected to obtain a full contraction behavior until reaching the steady state for very loose specimens, or contraction then dilation as for the void ratios decreases from very loose to loose and mid-dense samples. Meanwhile, a subtle preliminary dilatancy is unavoidable under all conditions tested. Although the samples are fully saturated with B values of 0.97 or higher and the errors of sample preparation using the wet-tamping method which results in anisotropy and preloading are eliminated, the dilation-contraction-dilation behavior still remains. Since we are struggling to go through correct tests achieveing contraction-dilation behavior, any comments to aid me in overcoming this issue would be helpful.

For example, if the consent form says that the data collected from the study will benefit humanity because the investigator will analyze the data and publish it, must the investigator make an honest attempt to do that?

Social evonomic rights in the gorm of workless wage is accepted in EU and refugees are entitled.

However, the satisfaction of this right ad part of rights to sustained living equality or economic equality due to hostility in adopted country causes other inequalities duch as work contract inequality: some work and get reimbursed some get without work.

Isn"t this inequality a serious one given that the right to life costs state benefits is a non fundamental human right ?

The essence of this question is to ascertain if Smart Contract with its Decentralized Transaction Protocols can be applied in Project Management. And if yes, which area of project management will it be applied for efficient project delivery?.

Another basis for the question is the growing concern of the importance of Smart Contract as an easy and security proof transaction platform that removes third party interference.

Blockchain bridges are known to use time locks for token swaps and concurrent operations between different accounts and contracts. Can we improve the security of time locks using verifiable delay functions?

Black hole is not consider to be infinity

· In an atom 99.999% (Say Approx.)is empty. This space is filled with dark matter, which help to bind atomic and subatomic particle together. This only happens when dark matter and dark energy combine.

· During Back hole formation, all atoms/matter, and energy squeeze to form its actual mass space 0.001%. Then the dark matter and dark energy in it are released in the universe. Thus, formed matter inside black hole known as say “NOSO” particles (Nothing but Something). Its existing state is not known.

· There for universe is expanding with the formation of black hole.

· Mass of galaxy is independent of its Size. The mass not only depends on the number/size of galaxy, but also the size of black hole. If the galaxy may be small, but the black hole present in the galaxy is so big, then that determines the total mass of the galaxy and its gravity.

· After forming black hole with all existing matter and energy in the universe, all black holes began to squeeze again form one black hole with 0.001% of space of universe. That may be the limit of squeezing.

· When the black hole squeezed the matter exceed with its limit, then it began to explode.

· During the explosion, due to extremely unstable NOSO matter spread and easily combines /attract with Dark matter and dark energy forms new atoms. The Universe contracts to a very small space.

· All the energy absorbed by Black hole with NOSO matter release tremendously and spread in the universe with the expanding universe.

· During the explosion of the single parent black hole, several small black hole will be spread over the newly formed universe.

· These processes continue and it is difficult to predict the age of the universe until to identify/detect dark matter and dark energy.

Center for a global earthquake forecast network in the countries of the Vrancea zone?

I appeal to the seismologists of the Vrancea zone. You know that the reliability of my method is about 100%.

Do you want a Global Network Center to be installed in the Vranci area, which will bring contracts and good profits?

Only this method can solve the problem of the Sendai program (UN).

In addition, the method is expanding into related areas, which will also bring good profits.

Two electrons, A at rest and B moving at high speed. According to the theory of relativity, there is a "Length Contraction and Time Dilation" effect in the space-time of the electron moving at high speed, but not in the electron at rest. Now if electron B is moving with velocity v, towards stationary electron A, at the moment of their collision:

(1) assuming that they are both point particles*, what is the measure of spacetime at the moment of their collision, where exactly is the measure? and is the spacetime of A and B the same spacetime?

(2) Assuming that they are structured particles‡, how is spacetime measured at an interface at the instant before their "collision"?

(3) Is the "Length Contraction and Time Dilation" effect¶ of SR absolute or relative ? Note that no matter how you set up the inertial systems, the spacetime of all inertial systems is a common spacetime that overlaps, and the difference is only in the relative coordinate values.

(4) What causes the "Length Contraction and Time Dilation" effect? Is it the "motion" itself, or is it the increase in "energy-momentum" caused by the motion? If the cause is energy-momentum, then it is consistent with GR?

A realistic example is the "gold-gold (Au + Au) collisions" at the Relativistic Heavy Ion Collider (RHIC) by the Solenoidal Tracker at RHIC (STAR ) Collaboration[1][2]. Two gold (Au) ions move in opposite direction at 99.995% of the speed of light. As the ions pass one another without colliding, two photons (?) from the electromagnetic cloud surrounding the ions can interact with each other to create a matter-antimatter pair: an electron (e-) and positron (e+). When two Au particles pass one another, approaching two times the speed of light, how is space-time measured here? And whose spacetime measure is it? This example gives the answer to the relationship between the speed of light and the platform of the light source, how the speed of light is interfaced with the speed of the Au. Light does not change its speed when Au keeps changing its speed, so what determines the difference in speed in between? It must be their spacetime measure. That is, we always have: Δx/Δt = c, assuming that Δx and Δt express spatial and temporal measures, respectively.

-----------------------------------------------------------

Notes:

* During Einstein's original proof [3], objects were considered as point particles, or independent of the structure of the object.

¶ The "Length Contraction and Time Dilation" effect in SR is not shown where exactly it manifests itself.

‡ Regardless of the structure, the electric field of the electron is radially dynamically diffuse and it is part of the electron.

It is intuitively understandable with three diagrams.

Read within 3 minutes and immediately know the Lorentz contraction is wrong.

Also you can find that the ultra speed of light are observed in your immediate daily life.

=============================================

Even if you are not a #physics expert, the content is understandable

Lorentzian contractions were recognized from two experiments 120 years ago.

The Michelson-Morley experiment and the Sagnac experiment.

I will review the experimental results to reveal the true nature of nature.

★Please see attached picture Fig2_San.jpg

Michelson Morley was an experiment confirming the existence of the aether.

A prism is used to split the light into two paths and finally join them together. Interference fringes of light are created when there is a speed difference between two light paths.

Result is

1. The interference fringes were small and aether could not be proved.

2. Earth's rotation and revolution do not affect the experiment

The Sagnac experiment was a set of Michelson-Morley experiments mounted on a rotating disk. expected the same result

★Please see attached picture Fig1_MM.jpg

However, for some reason, large interference fringes were observed.

Everyone didn't find the reason at the time

So the physics world accepted the Lorentz contraction hypothesis that the rotation speed of the disk shortens the distance, changes the speed of light, and creates interference fringes.

The real natural phenomenon shown by the Sagnac experiment is:

The revolution speed of the earth is added to the light emitted from the light source. As the disk rotates, the addition of the earth's revolution speed changes continuously. It is Doppler effect of light.

In particular, when the direction of light and the direction of revolution are orthogonal, the added speed becomes zero. Maximum interference fringes are produced.

★Please see attached picture Fig3_Evo.jpg

The speed which is added to the orinal light speed(3*10**8 m/sec) is :

1. The case of Revolution speed : 30000m/sec

2. The case of Rotation speed : 460m/ sec

3. Disk rotates speed of Sagnac experiment might be less than 10m /sec

The Lorentz contraction hypothesis cannot explain the large interference fringes in Sagnac's experimental results because of too slower speed.

Because

like

ciric, rus, f-contraction, suzuki contraction etc

There is a contradiction in Schwarzschild's black hole radius law. In order to mass transformation in the right side and length transformation in the left side and according to the length contraction of Lorentz-Fitzgerald on the left side, the two sides are unequal. This gives us three possibilities. The first possibility is Schwarzschild's black hole radius law is wrong. The second possibility is that the laws of the universe change from a frame To the last that is, the relativity is wrong. The third possibility is that the constants change from one frame to another

Derivative instrument and hedging activities improved the ongoing consistency in the current environment as the integrity and credibility endeavor in the future regarding the complexity to access the effectiveness of option values to the criterion related to the financial contracts and forward contracts in hedging relationship concerning the utility choices.

Ricci scaler is a tensor contraction of Ricci tensor(a 2-4 contraction of Riemann tensor) , i saw people saying it compare the volume of ball in curved surface to the ball in Euclidean surface, can we relate this geometrical meaning to the formula Ricci scaler

I have done EFA in SPSS with a sample of 305; only one factor was extracted in PCA. It indicated unidimensionality. Is this contract good to go ahead for CFA? What does it indicate?

Construct had 5 subscales; 14 items.

Thanks.

Gig workers is type of worker community who work on contract basis and Employer is not guaranteed on job security.

I continue to be active in research.

The information provided by Researchgate continues to be very useful for me.

I would be very grateful if Researchgate does NOT cancel out my contract but, on the contrary , allows for it to continue to be active after that date

Contracts can be formed without offer or acceptance.Rather, based on the principle of freedom from form, a sufficient agreement based on the intention of contractual obligation is the reason for the formation of a contract.According to the provisions of the principles, there is no need for the traditional model of offer and acceptance.

This claim is shared by some teachers, professors etc.

Sharing one's most valuable insights and accept the prospects of his students be coming part of a "knowable state of an advanved mind", is not something every teacher is consciously willing to do.

This thesis is in some aspects compatible with the political philosophy associated with the right, that admits Humans are inherently bad and are expected to underdeliver and not be generous to others without this benefit ing their agenda. Hence, if in teaching there is no clear social contract but vaque and general expectations that cannot asses deepest commitment to seeing others succeed at higher standards but a mere commitment to not prevent this by eye catching or basic omissions, the question above is valid.

I am interested in learning Hyperledger Fabric 2.x and smart contracts to create my own API. I took a course in Udemy but it was based on Composer, that was deprecated since 2019. Do you have any idea about a great course preferely in Java or JavaScript than Go Lang?

Thank you

Our group has recently acquired a flow cytometer from another department, just looked at the service contract, it's very expensive.

I cannot seem to find another company that will routinely service this type of equipment.

Thanks for your help

The above question was posed by great Lucretius (98 - 55 B. C.) and had offered a curious explanation: "This happens because in summer the earth is relaxed by the warmth and any particles it may contain of its own heat are dispersed into the air. ...Conversely, when all the earth is compressed by cold and contracts and virtually congeals, it naturally happens that in contracting it squeezes out any heat it may contain into the wells." [1, 2]

Does anyone know a business that can be contracted to extract DNA from soil samples and sequence plant and fungal genes via metabarcoding? Thanks!

Hi, for a study I'm doing I need to get a view about the IO of the freight railroads transportation sector in Chile. Let me give you a bit of background. I'm just concern about the Railroad public company EFE (Empresa de Ferrocarriles del Estado) network, located in the center southen part of the country. There are two private freight operators which pay access charges established in two separate but equal acces contracts, which are regulated by EFE, a part of the contract) that follow the typical natural monopoly regulated price structure (a fix charge for right of using the rails, a variable chage in terms of kilometers of network usage and a variable charge in terms of volumes transported (TKBC, gross tons kilometers). In euros of 2014 per 1.000 gross tonnes, Chile's vharges (4 euros) was the fifth more expensive access charge compared to a large pool of european countries, and since then access charges has gone up and are currently in 5 euros per 1.000 gross tonnes. Although there are only two freight operators (yet it is open to more but have had no entrance since 2000, EFE operates only in the passenger segment) it is a very contestable market (trucks competition is ample and benefited from indirect government support). How would you be modelling a market like that? Bilateral monopoly with different bargainning powers? Natural Monopoly waters down and duopoly waters up (they curretly compete only in a fraction of the network but potentially all over)? or local monopolies water up? To add more complexity one of the freigth operators is vertically integrated with one important maritime port, and prevents competition from the other around that area. What reference you advice me? I need something simple, it is a study that is aimed at providing policy insight based on understanding the sector's IO, not on publishing an academic paper. Thank you in advance.

If possible, give an example of a continuous function defined on a convex subset of a Banach space $X$ satisfies Kannan contraction but does not satisfy Banach contraction.

Dear all,

I´m looking for an easy to conduct cell culture assay to measure the contraction of cardiomyocytes.

I would be thankful for any idea!
