Handbook of Industrial Water Soluble Polymers - Original PDF
نویسندگان: خلاصه: Natural and synthetic water soluble polymers are used in a wide range of familiar industrial and consumer products, including coatings and inks, papers, adhesives, cosmetics and personal care products. They perform a variety of functions without which these products would be significantly more expensive, less effective or both.Written for research, development and formulation chemists, technologists and engineers at graduate level and beyond in the fine and specialty chemicals, polymers, food and pharmaceutical industries, the Handbook of Industrial Water Soluble Polymers deals specifically with the functional properties of both natural and synthetic water soluble polymers. By taking a function based approach, rather than a "polymer specific" approach the book illustrates how polymer structure leads to effect, and shows how different polymer types can be employed to achieve appropriate product properties.
Synthetic Polymers for Biotechnology and Medicine - Original PDF
نویسندگان: خلاصه: One of the most powerful group of chemicals in the body are organic compounds collectively referred to as hormones. The glands responsible for the production and release of hormones comprise the endocrine system. Endocrine activities have been identified in certain organs, such as the heart, kidneys, duodenum, liver and the islets of Langerhans in the pancreas (which contains the insulin gland), which are normally associated with other system functions. There have been numerous attempts to replace organ function using cell transplantation including direct injections of dissociated cells into organs such as the liver, kidney or spleen.1-5 Subcutaneous and intraperitoneal routes have also been evaluated.6-10 More recent investigations have applied extracellular matrix polymers as structural supports for cell transplantation and immunoprotection.11,12 Potential medical applications of such “artificial cells” or “tissue engineered” organoids include an extracorporeal bioartificial liver for detoxification,2 artificial red blood substitutes,13 the extracorporeal artificial kidney for hemodialysis,14 immunosorbents15 and drug delivery systems.16The transplantation of immunoisolated (microencapsulated) cells represents another emerging area in biotechnology research and commercialization. Under such a scenario, the encapsulated cells, which could be a xenograft, would be hidden from the immune system of the body, but would still be able to respond to extracellular stimuli (e.g., blood glucose), with the required hormone, in the case of diabetes therapy insulin, secreted into the systemic circulation. Other applications of the microencapsulation concept include the encapsulation of genetically modified cells, which represents a novel approach to somatic gene therapy.17 This chapter will review recent advances in cell encapsulation from material science, technological and tissue-related perspectives. Cell coating, microencapsulation devices and bioartificial organs will be discussed with the artificial pancreas and treatment of diabetes used as a case study denominator throughout the review.

Made to Stick: Why Some Ideas Survive and Others Die - PDF
نویسندگان: خلاصه: This is a crash course on how to make your ideas understood and remembered by other people. Whether you want to write a book, sell a product, or become a better storyteller, you’ll learn a useful playbook for understanding what makes an idea good and how to cement it into the mind of others. Key Takeaways Making ideas stick To make ideas stick, you can leverage the SUCCESs framework: Simplicity – makes something understandable Unexpectedness – makes people pay attention Concreteness – makes people understand and remember Credibility – makes people agree and believe Emotional – Makes people care Story – Inspires people to act The book is organized around understanding each of these six pillars of making ideas stick. 1. Simplicity Find the core idea Sticky ideas must be simple. Simplicity means you have found the core of the idea. You have stripped an idea down to its critical essence. For example, Southwest Airlines prioritizes one mission above all else: “We are the low-fare airline.” The mission is clear and simple enough to guide employee decisions. Don’t bury the lead Start with the most important idea. Journalists are taught early on not to “bury the lead.” The same is true for conveying your core idea. Whether you’re giving a talk, writing copy for a landing page, or sharing a story, start with the lead. That means getting rid of the fluff and centralizing around the core idea. What’s a simple idea? “Short sentences (compact) drawn from long experience (core). We are right to be skeptical of sound bites, because lots of sound bites are empty or misleading—they’re compact without being core. But the Simple we’re chasing isn’t a sound bite, it’s a proverb: compact and core.” Say one thing instead of three “When you say three things, you say nothing. When your remote control has fifty buttons, you can’t change the channel anymore.” Even if you have four good points, it’s better to focus on the one that matters most. Cutting the fat sometimes means cutting good ideas. Use familiar concepts and schemas Describe something in terms of a concept that’s already familiar. For example, imagine you wanted to explain what a pomelo was to someone who didn’t know. “Explanation 1: A pomelo is the largest citrus fruit. The rind is very thick but soft and easy to peel away. The resulting fruit has a light yellow to coral pink flesh and can vary from juicy to slightly dry and from seductively spicy-sweet to tangy and tart.” “Explanation 2: A pomelo is basically a supersized grapefruit with a very thick and soft rind.” Explanation 2 wins because most people are familiar with a grapefruit, and that familiarity can allow them to more easily grasp what a pomelo is. Great teachers use schemas that people are familiar with: “Good teachers intuitively use lots of schemas. Economics teachers, for instance, start with compact, stripped-down examples that can be understood by students who have no preexisting economics schemas. “Let’s say that you grow apples and I grow oranges. We’re the only two people around. Let’s also say that we’d prefer to eat some of both fruits rather than all of either. Should we trade? If so, how do we go about doing it?” Avoid the curse of knowledge “Once we know something, we find it hard to imagine what it was like not to know it. Our knowledge has “cursed” us. And it becomes difficult for us to share our knowledge with others, because we can’t readily re-create our listeners’ state of mind.” You know you’re suffering from the curse of knowledge when you want to be accurate to the point where most people don’t understand. It’s better to break down things into simple terms so that more people can grasp what you’re saying than to get all of the precise details correct for someone who is not an expert. How to pitch It’s more effective to use things people are already familiar with. For example, you’re new company is the “Uber for x” or your new movie is “Jaws on a spaceship.” People can quickly grasp what it is you’re trying to do and not be bogged down by all the nuances of the project. 2. Unexpectedness A core challenge of communicating your ideas is getting people’s attention, especially if you’re not already famous or known as a highly credible source in a particular field. Unexpectedness can help. Break a pattern “The most basic way to get someone’s attention is this: Break a pattern. Humans adapt incredibly quickly to consistent patterns. Consistent sensory stimulation makes us tune out.” For example, think about how you feel when airlines begin reviewing safety information about life jackets, oxygen masks, and so on. You probably tune out because it’s boring and familiar. But if a safety instructor started making jokes and broke the script, that might actually get your attention. It’s unexpected, and all of a sudden you’re listening to something that you would have otherwise ignored. Power of surprise “So if emotions have biological purposes, then what is the biological purpose of surprise? Surprise jolts us to attention. Surprise is triggered when our schemas fail, and it prepares us to understand why the failure occurred.” Breaking a pattern can help get people’s attention by surprising them, but you also need to figure out how to keep their attention. For example, a clickbait headline may be useful in getting people to view your article, but it won’t ensure that people read the full piece. If they don’t read the piece, then what’s the point? You may increase your pageviews, but you don’t increase your influence. Power of mystery “Curiosity is the intellectual need to answer questions and close open patterns. Story plays to this universal desire by doing the opposite, posing questions and opening situations.” A mystery story draws people in. It incites curiosity and gets them wondering about the answer. Beginning with a mystery story can get the audience bought into the puzzle that you’d like to solve with them. People want to know: “What will happen next? How will it turn out?” That’s what keeps them invested in the story. You create a mystery by first opening gaps. Those gaps should make the audience want to know what happens next. A good mystery is only useful if the person reading about it wants to know what happens next. You can then close the gaps via the story. An important part of closing the gap is how you sequence information. A good story drops clues incrementally, keeping the reader hooked. 3. Concreteness Telling concrete stories that reveal deep truths is a more powerful way to share a message than listing out an abstracted truth. A good example is “The Fox and the Grapes” by Aesop. One hot summer day a Fox was strolling through an orchard. He saw a bunch of Grapes ripening high on a grape vine. “Just the thing to quench my thirst,” he said. Backing up a few paces, he took a run and jumped at the grapes, just missing. Turning around again, he ran faster and jumped again. Still a miss. Again and again he jumped, until at last he gave up out of exhaustion. Walking away with his nose in the air, he said: “I am sure they are sour.” It is easy to despise what you can’t get. We can all relate to and remember this story, and it has more meaning than if someone just said, “It is easy to despise what you can’t get.” The concrete details of the fable bring meaning to a common blunder of the human psyche. Abstraction “Abstraction is the luxury of the expert.” Experts often share ideas in complicated terms that only fellow experts can understand. They are plagued by the Curse of Knowledge and want to show how informed they are about a topic. But this type of abstraction is unhelpful to a novice. It clouds the message that is being shared to the point that it is never understood. Concrete language, including vivid and digestible details, can help bridge this gap. In part, that’s because concrete words are more memorable than abstracted ones. If I wanted to teach you about accounting, for example, I could talk about income statements, balance sheets, and accounts receivable. Or, I could ask you to help figure out if two students selling a product online have a feasible business idea. The specific example of students (who are like you) can help you put the abstracted concepts into practice in a way that can make them tangible and digestible. The result is that you learn about the core concepts of accounting without having to study a dictionary of confusing terms. 4. Credibility Credibility is an important part of making an idea stick, but how do you establish credibility? There are a few ways – statistics are one of them. Using statistics effectively “Statistics are rarely meaningful in and of themselves. Statistics will, and should, almost always be used to illustrate a relationship. It’s more important for people to remember the relationship than the number.” Let’s say you wanted to talk about the importance of employee dissatisfaction in your workforce. You could site a number of statistics: Only 25% of people say they have a clear understanding of their job Only 15% of people were enthusiastic about their job Only 30% of people say they have enough resources to execute key goals These statistics are helpful, but they are still very abstract. You might come away feeling that there is a lot of dissatisfaction at the company, but no idea of how serious this issue may be. A more useful way to describe what’s going on is to compare the numbers to something people have a grasp of. Drawing from an example in Steven Covey’s book, you could say something like: “If your workforce was a soccer team, only 4 out of 11 players would know which goal is theirs. Only 2 out of 11 would care. Only 2 of the 11 know what position they play and know exactly what they are supposed to do. And all but two players would, in some way, be competing against their own team members rather than the opponent.” By humanizing the statistics in this way, it’s easy to understand that something needs to be fixed. In fact, it would seem ridiculous if an organization didn’t figure out how to change things quickly. Another example is evaluating whether or not you should make an investment. You could say, “The cost of making this investment would be about $500 per employee annually.” In these terms, you need to figure out if the benefit of the investment is more than $500. One way that you can frame the “Is it worth it?” question is to say: “If you believe you can increase an employee’s productivity by one to two minutes a day, you’ve paid back the cost of the investment.” That makes the investment a no-brainer, versus an abstracted cost/benefit calculation does not. Sinatra Test One way to establish credibility is to leverage the Sinatra Test: If you can make it there, you can make it anywhere. This is particularly useful for small or unproven businesses. The idea is that you prove yourself with a big and important customer under difficult circumstances, and that action alone gives people confidence that you can do that for many more people. “We made sure that all Amazon deliveries arrived on time during Christmas” is a much more powerful signal to other potential customers than “98% of our deliveries arrive on time.” 5. Emotional “If I look at a mass, I will never act. If I look at the one, I will.” – Mother Teresa If I tell you that 5 million African children die of malaria every year, you will likely feel bad about the problem. But how motivated will you be to act? It’s hard to conceptualize 5 million people in suffering, and you may feel like whatever you do will be an unhelpful drop in the bucket. If, on the other hand, I tell you that Rhonda, a young girl in Africa may die from a preventable disease, and all you need to do is donate $50 annually to save her life, that’s a no-brainer. You’re going to be much more likely to donate to the cause and feel. like you’re doing something really meaningful. Charities have tapped into this quirk of human psychology by sharing the stories of individual people who are suffering from things that impact large numbers of people. The individual story taps into our emotions in ways that large and scary numbers don’t. Creating an emotional response inspires people to act. In the case of charities, sharing single detailed stories of specific individuals leads to more donations and impact. Semantic stretch When we overuse a term that generates an emotional response, it leads to a dampening of the emotional response. For example, let’s say we see artsy people that like to buck societal norms and call them “hipsters.” That word has meaning and gives us the feeling of what a hipster is and represents. But as the term gets adopted more widely, we start calling more and more things “hipster.” Suddenly, all modern designs or people wearing specific types of clothing are hipster. Or maybe even bucking a societal trend in and of itself is “hipster.” Over time, as the word expands to describe many more things than the original meaning, it loses its emotional resonance because it’s been overused. This concept is caused semantic stretch. Leveraging self-interest People care about themselves and what they want. So if you’re writing copy, it can be useful to put it in terms that highlight the ways in which an individual may benefit. Often, it’s helpful to give people a way to visualize the value of what you’re offering. The tangibility of your visualization, rather than the magnitude of the change you’re promising, can lead to the most action. Maslow’s Pyramid Tapping into people’s self-interest is useful, but people have a wide range of needs. Depending on what you’re offering, you may want to tap into the wider set of their needs. Maslow’s Pyramid is a good framework for understanding the full range of what people may care about: Transcendence: help others realize their potential Self-actualization: realize our own potential, self-fulfillment, peak experiences Aesthetic: symmetry, order, beauty, balance Learning: know, understand, mentally connect Esteem: achieve, be competent, gain approval, independence, status Belonging: love, family, friends, affection Security: protection, safety, stability Physical: hunger, thirst, bodily comfort To create an emotional response, you can convey value in terms of some of these needs. 6. Story Mental simulation If you ask someone to think about a certain future to simulate a problem they need to solve, they will often come up with a more vivid and accurate understanding of the situation. They will see things that they otherwise ignored in an abstracted planning process. For example, imagine you quit drinking, and you were worried about a party with friends coming up. Instead of arriving at the party sober and hoping that your self-control could win out, you could visualize the event. Visualize the subtle peer pressures you might face and what you could do in that situation. If you do that, you’re more likely to be prepared and comfortable with this potentially challenging social situation. Jared at Subway The story of Jared, the guy who lost hundreds of pounds eating Subway sandwiches, lead to massive growth for the Subway chain. It took a savvy and persistent group of people who first spotted and then believed in the story before the company decided to feature it, but it ended up being one of the most successful stories for fast-food sales growth than any other. Instead of “Subway has low-fat sandwiches,” people saw that “Jared, an everyday guy, lost a ton of weight by eating Subway every day.” That story had a lot more staying power than a description of the nutritional properties of the sandwiches. Common story plots You can leverage various types of common stories. Challenge Plot: Someone overcomes a formidable challenge and succeeds (e.g., David and Goliath). Connection Plot: People who develop a relationship that bridges a gap – racial, class, ethnic, religious, demographic, etc. (e.g., everyone drinks Coca Cola) Creativity Plot: Someone makes a mental breakthrough, solving a hard puzzle, or finding an innovative solution to a problem . Stories are particularly effective in dismantling the Curse of Knowledge. By sharing a simple and concrete story that people can relate to, you can move away from abstracted lessons and move toward a narrative that people can follow and take away something valuable.
How Nuclear Weapons Spread: Nuclear Weapon Proliferation in the 1990s (Operational Level of War) - Original PDF
نویسندگان: خلاصه: HOW NUCLEAR WEAPONS SPREAD The production of the first nuclear fission chain reaction in 1942 ushered in a new era in history and science. With both detrimental and beneficial effects, the nuclear age had begun—an age which would have far-reaching effects on the lives of subsequent generations. In How Nuclear Weapons Spread, Frank Barnaby examines the implications of nuclear weapons, and considers the close relationship between peaceful and military nuclear programmes. The book looks in detail at the nuclear programmes of Third World countries which have or could soon have the bomb, such as Israel, Pakistan and India, as well as those which are thought to be developing their nuclear capabilities—such as Iran and North Korea. Even more alarming is the threat that terrorists might acquire nuclear weapons. Frank Barnaby assesses the reality of this risk, and considers methods of checking the spread of these weapons. The book also contains detailed descriptions of the components needed for nuclear fission and thermonuclear weapons, and discusses the need to test these weapons, as well as the difficulties of disarming and disposing of nuclear materials. How Nuclear Weapons Spread will be of great interest to students of International Politics, International Relations and Strategy Studies. Frank Barnaby is a former Guest Professor at the Free University in Amsterdam and a former Director of the Stockholm International Peace Research Institute. He is currently a defence analyst and is the author of many books, including Star Wars, 1987, The Automated Battlefield, 1987 and The Role and Control of Weapons, 1992.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
