Carbohydrates contain sugar, starch, hydrogen and oxygen – so they make a good fuel source in the right circumstances. When flour particles have a very large surface area and when suspended in air, in the right mix,they have a large supply of yet more oxygen.

. While LMS vendors seek to create an environment that provides an all-encompassing PLE, the fact that they are closed networks and that they are platforms built to meet the needs of entire institutions means that they usually are not personalised enough to meet the needs of a connected learner, who is (most often) already used to the flexibility and ownership web 2.0 tools provide.

Drum or bag – a mechanism that requires replacement of the drum or bag that collects the matter.

The air to cloth ratio is the amount of air that passes through a square foot of the filter. The lower the ratio, the higher quality of the filtration system's efficiency.

Though a fan or blower may have a simple design, when installed in a dust collection system, several factors have to be considered. First of those factors is the volume of air that needs to be moved. This is measured in cubic feet per minute (CFM). The next consideration is the static pressure throughout the whole system. Other variables are the temperature, substances in the air, and the level of moisture.

Dust collection systems have ductwork to draw in the air, an air purifier, and receptable.

According to some reports, food processing is the largest category for combustible dust explosions in manufacturing, accounting for almost 25 percent of incidents.

properly sized and manifolded to maintain a consistent minimum air velocity required to keep the dust in suspension for conveyance to the collection device.

Dust collection systems work on the basic formula of capture, convey and collect.

It can be as simple as a basic pass-through filter, a cyclonic separator, or an impingement baffle.

Mass protests against Russia’s aggression combined with existing political pressure to move more quickly on climate change might lead to new policies to do yet more.

In 2022, successful business leaders will need to address the continued disruption from the last couple of years and will do so through four human-centric strategies. All of them elevate the importance of individuals. All of them improve the employee-employer relationship. All of them test the degree to which leaders embrace innovative management styles. All of them will impact the company's ability to retain and recruit top talent. And all of them have an impact on a business's bottom line

Operating System MCQ

The dopamine reward system has also been shown to bestimulated by most drugs of abuse and plays an important rolein addiction [33]. An important question is whether jhanameditators are subject to addiction and tolerance effects thatcan result from stimulation of the dopamine reward system.

We report the first neural recording during ecstatic meditations called jhanas and test whether a brain reward system plays a rolein the joy reported. Jhanas are Altered States of Consciousness (ASC) that imply major brain changes based on subjective reports:(1) external awareness dims, (2) internal verbalizations fade, (3) the sense of personal boundaries is altered, (4) attention is highlyfocused on the object of meditation, and (5) joy increases to high levels. The fMRI and EEG results from an experienced meditatorshow changes in brain activity in 11 regions shown to be associated with the subjective reports, and these changes occur promptlyafter jhana is entered. In particular, the extreme joy is associated not only with activation of cortical processes but also with activationof the nucleus accumbens (NAc) in the dopamine/opioid reward system. We test three mechanisms by which the subject mightstimulate his own reward system by external means and reject all three. Taken together, these results demonstrate an apparentlynovel method of self-stimulating a brain reward system using only internal mental processes in a highly trained subject.

had it been up to the folks in charge in Glynn County, the jury never would have seen that evidence. To say the system worked in this case is like saying your car made it home—after your entire family had to get out and push it miles down a dirt road.

So to sum things up what caused life's major evolutionary transitions the answer is cooperation major transitions begin when a group of organisms join forces to better survive and reproduce if cooperation continues long enough a new super organism may Emerge one that can then go [on] to reproduce and evolve as a whole and 00:07:42 The pathway that led [to] animals along with humankind [at] least three major transitions have been identified resulting in four layers of Life within your own body

Each new layer of Life is the result of what scientists call a major evolutionary transition? What was the cause of these transitions the answer is? Cooperation a Major Transition starts when free living creatures team up to form a cooperative group in the early stages of cooperation Participants are free to come and go as they [please] [if] a group sticks together long enough however 00:04:51 Division of labor will often evolve different participants begin specializing in different tasks as time goes on Individuals may become so specialized that they can no longer survive on their own [if] the entire group becomes locked into cooperation Depending fully on one another to survive and reproduce a new super organism has been forged and they made your evolutionary transition is complete 00:05:16 From this point on the entire group will evolve together as one Models describing natural situations that might promote the evolution of major transitions have been put forth by scientists such as John Maynard Smith [fior] Sonck Mary stuart West and w d hamilton using these models Researchers have been able to Mimic natural scenarios in the lab Allowing us to directly witness the beginnings of major transitions [evolved]

we want to focus on how humans fit into our category goal framework here and we'll use this figure as a roadmap 00:42:18 starting with the center section looking that looks at how events that affect the species and clay level and so what stands out here for humans is our 00:42:28 complex spoken language which greatly enhances our communication and has long been thought of as a met due to leaps in the way that we transmit information between individuals 00:42:40 but this met really wouldn't have been possible without a major competitive transition so the specific regions in the brain that are associated with greater cognition and language ability 00:42:52 and also our larger brain size which is correlated with functionality and our spoken language allows human societies to gather greater amounts of level 3 or learned 00:43:07 information than would ever be possible within any one individual's lifetime and this really turns up the dial on the magnitude at which cultural evolution affects us as a 00:43:19 species and allows us to adapt and construct our environments in different ways cultural innovations are also not dependent on random beneficial mutations but can 00:43:32 arise intentionally and this has major impacts for how quickly and at what level we can affect our ecosystems 00:43:43 so when we come back to the figure and we've layered on complex spoken language now we can look at the level of ecosystem change that's occurred because of this and see if it's enough to bring 00:43:55 us to a major systems transition and here we argue that the answer is no if we would have just stopped at spoken language our global impact would never have reached the level 00:44:07 that it takes to drive an mst but we do argue that this spoken language was actually a facilitating evolutionary transition for events that directly paved the way 00:44:19 for an mst so human spoken language is a facilitating transition for symbolic representation of instructional information so the met and the mechd that make up 00:44:33 complex spoken language are actually a fit for being able to write things down and being able to write things down onto abiotic mediums allows us to increase the amount of information that 00:44:47 we can store the accuracy of the stored information and the efficiency of transmission and this has an especially high impact for oblique transmission because 00:44:59 being able to inscribe information can potentially immortalize it and then individuals far in the future can build upon it and so being able to build upon 00:45:12 uh generations of information through symbolic representation of language is really a key for the expansion of technological innovations that have expanded the realized niche of humans so 00:45:25 we have spread across every continent made major impacts on most ecosystems and a part of what has allowed us to do this is the technology that we've designed uh based upon large amounts of 00:45:39 inscribed language and some of these technologies actually allow us to manipulate or avoid the processes of natural selection and some of the those examples are listed here 00:45:53 and so when we go back to our figure and layer on the potential to inscribe language and then re-look at ecosystem level changes we think that here due to due to the 00:46:06 technological innovations and global expansion that's come with being the only species to store this much level three information that the answer is now yes 00:46:19 and when an mst occurs the context in which this entire cycle takes place completely shifts because now the global ecosystem is playing by a modified set of rules that are 00:46:33 set forth by the mst so this brings us to the question are humans the last mst or are there other mets and mechs forthcoming that will drive a new 00:46:45 major systems transition

you are looking at major 00:12:17 evolutionary transitions so one can start with the idea that initially what has to happen is individuals kind of have to tolerate each other so in other words competitors 00:12:31 have to be willing to form into those simple groups and those groups have to have some kind of benefit for their existence and continuance then berkshire said well the next step 00:12:44 in this transition is what can go from formation to maintenance so if you go from a simple group to society again there are there are rules there are maybe individuals that belong to certain 00:12:56 societies and rather than sort of a fission fusion kind of uh coming together going apart these societies maintain themselves these groups maintain themselves over 00:13:08 longer periods of time and there are more benefits and there may in fact be more conflicts that have to be worked out to keep the societies to maintain the societies 00:13:19 finally there would be the step into this group transformation again what what what kuala and strassmann might have called organismality so now that the groups subsume their kind of 00:13:32 individual goals into a collective goal for all of them and again the idea here is that that that one has to happen is conflict has to be somehow managed and reduced 00:13:44 such that the groups can actually transform into this coherent whole single individual and some of the key points in in in burke's sort of 00:13:55 pathway to to to transformation is that the first two steps are can truly be bidirectional in other words uh societies can go back to being simple groups and simple groups can go 00:14:10 back to being competitive just competitors so in other words those aren't sort of absorbing states but the argument is that once once you sort of get to that group transformation that last blue arrow you 00:14:23 have transformed in a way that it is hard or impossible to really go backwards and what burke argued is that that process those those various steps and 00:14:34 particularly that last transformative step is strongly driven often by inclusive fitness kin selection so in other words going back to that continuum 00:14:46 of the types of groups that they can form fraternal groups are much more likely to to transform into these higher level organisms than 00:14:58 uh egalitarian groups

Professional musicians, concert pianists get to know this instrument deeply, intimately. And through it, they're able to create with sound in a way that just dazzles us, and challenges us, and deepens us. But if you were to look into the mind of a concert pianist, and you used all the modern ways of imaging it, an interesting thing that you would see 00:11:27 is how much of their brain is actually dedicated to this instrument. The ability to coordinate ten fingers. The ability to work the pedal. The feeling of the sound. The understanding of music theory. All these things are represented as different patterns and structures in the brain. And now that you have that thought in your mind, recognize that this beautiful pattern and structure of thought in the brain 00:11:52 was not possible even just a couple hundred years ago. Because the piano was not invented until the year 1700. This beautiful pattern of thought in the brain didn't exist 5,000 years ago. And in this way, the skill of the piano, the relationship to the piano, the beauty that comes from it was not a thinkable thought until very, very recently in human history. 00:12:17 And the invention of the piano itself was not an independent thought. It required a depth of mechanical engineering. It required the history of stringed instruments. It required so many patterns and structures of thought that led to the possibility of its invention and then the possibility of the mastery of its play. And it leads me to a concept I'd like to share with you guys, which I call "The Palette of Being." 00:12:44 Because all of us are born into this life having available to us the experiences of humanity that has come so far. We typically are only able to paint with the patterns of thoughts and the ways of being that existed before. So if the piano and the way of playing it is a way of being, this is a way of being that didn't exist for people 5,000 years ago. 00:13:10 It was a color in the Palette of Being that you couldn't paint with. Nowadays if you are born, you can actually learn the skill; you can learn to be a computer scientist, another color that was not available just a couple hundred years ago. And our lives are really beautiful for the following reason. We're born into this life. We have the ability to go make this unique painting with the colors of being that are around us at the point of our birth. 00:13:36 But in the process of life, we also have the unique opportunity to create a new color. And that might come from the invention of a new thing. A self-driving car. A piano. A computer. It might come from the way that you express yourself as a human being. It might come from a piece of artwork that you create. Each one of these ways of being, these things that we put out into the world 00:14:01 through the creative process of mixing together all the other things that existed at the point that we were born, allow us to expand the Palette of Being for all of society after us. And this leads me to a very simple way to go frame everything that we've talked about today. Because I think a lot of us understand that we exist in this kind of the marvelous universe, 00:14:30 but we think about this universe as we're this tiny, unimportant thing, there's this massive physical universe, and inside of it, there's the biosphere, and inside of that, that's society, and inside of us, we're just one person out of seven billion people, and how can we matter? And we think about this as like a container relationship, where all the goodness comes from the outside to the inside, and there's nothing really special about us. 00:14:56 But the Palette of Being says the opposite. It says that the way that we are in our lives, the way that we affect our friends and our family, begin to change the way that they are able to paint in the future, begins to change the way that communities then affect society, the way that society could then affect its relationship to the biosphere, and the way that the biosphere could then affect the physical planet 00:15:21 and the universe itself. And if it's a possible thing for cyanobacteria to completely transform the physical environment of our planet, it is absolutely a possible thing for us to do the same thing. And it leads to a really important question for the way that we're going to do that, the manner in which we're going to do that. Because we've been given this amazing gift of consciousness.

I think Marshall McLuhan knew it all. I really do. Not exactly what it would look like, but his view and Postman’s view that we are creating a digital global nervous system is a way they put it, it was exactly right. A nervous system, it was such the exact right metaphor. And he didn’t — it’s not that they saw it exactly, but I really love those mid-century media critics because they saw something happening clearer than we see it now. And it is a nervous system. I’m a huge Marshall McLuhan stan.

For psychological purposes there are two major changes in recent ideas of nervous function. One concerns the single cell, the other an "arousal" system in the brain stem. The first I shall pass over briefly; it is very significant, but does not bear quite as directly upon our present problem. Its essence is that there are two kinds of activity in the nerve cell: the spike potential, or actual firing, and the dendritic potential, which has very different properties. There is now clear evidence (12) that the dendrite has a "slow-burning" activity which is not all-or-none, tends not to be transmitted, and lasts 15 to 30 milliseconds instead of the spike's one millisecond. It facilitates spike activity (23), but often occurs independently and may make up the greater part of the EEG record. It is still true that the brain is always active, but the activity is not always the transmitted kind that conduces to behavior. Finally, there is decisive evidence of primary inhibition in nerve function (25, 14) and of a true fatigue that may last for a matter of minutes instead of milliseconds (6, 9). These facts will have a great effect on the hypotheses of physiological psychology, and sooner or later on psychology in general. Our more direct concern is with a development to which attention has already been drawn by Lindsley (24): the nonspecific or diffuse projection system of the brain stem, which was shown by Moruzzi and Magoun (34) to be an arousal system whose activity in effect makes organized cortical activity possible. Lindsley showed the relevance to the problem of emotion and motivation; what I shall attempt is to extend his treatment, giving more weight to cortical components in arousal. The point of view has also an evident relationship to Duffy's (13). The arousal system can be thought of as representing a second major pathway by which all sensory excitations reach the cortex, as shown in the upper part of Fig. 1; but there is also feedback from the cortex and I shall urge that the psychological evidence further emphasizes the importance of this "downstream" effect. In the classical conception of sensory function, input to the cortex was via [p. 249] the great projection systems only: from sensory nerve to sensory tract, thence to the corresponding sensory nucleus of the thalamus, and thence directly to one of the sensory projection areas of the cortex. These are still the direct sensory routes, the quick efficient transmitters of information. The second pathway is slow and inefficient; the excitation, as it were, trickles through a tangled thicket of fibers and synapses, there is a mixing up of messages, and the scrambled messages are delivered indiscriminately to wide cortical areas. In short, they are messages no longer. They serve, instead, to tone up the cortex, with a background supporting action that is completely necessary if the messages proper are to have their effect. Without the arousal system, the sensory impulses by the direct route reach the sensory cortex, but go no farther; the rest of the cortex is unaffected, and thus learned stimulus-response relations are lost. The waking center, which has long been known, is one part of this larger system; any extensive damage to it leaves a permanently inert, comatose animal.

Cut a dado groove with a 3/4” diameter router bit and you’ll almost certainly have a too-loose joint when you try to plug some 3/4” plywood in place. Under the guise of metrification, sheet material thicknesses have all shrank enough to cause problems with joinery if you rely on the old, Imperial thickness designations. And besides, material thickness varies enough from sheet to sheet that it can make a difference when it comes to prominent joinery. This is even true in the USA that still uses Imperial more or less exclusively. Sheet goods remain thinner than their name specifies.

"As it is, we have the wolf by the ear, and we can neither hold him, nor safely let him go. Justice is in one scale, and self-preservation in the other," Jefferson wrote a fellow politician almost 30 years after Carter's deed of gift.

One problem is the literal ['a','b','c'] will be inferred as type string[], so the type system will forget about the specific values.

* Now it's correct within the laws of the type system, but makes zero practical sense, * because there exists no runtime representation of the type `Date & string`. * * The type system doesn't care whether a type can be represented in runtime though.

Analytical thinking takes something apart, system thinking understands what the thing is a part of.Analytical Thinking identifies the properties and behaviors of the parts taken separately, System Thinking understands the behavior of the bigger whole which the thing is a part of.Analytical Thinking aggregates the understanding of the parts into an understanding of the whole, System Thinking understands the role or function of the thing as a part of the whole.

Analytical thinking helps us understand how stuff works, system thinking helps us understand why stuff works the way it does.
