Laser treatment is being employed for several applications including wound healing, bone repair, pain-relief, etc. The basic principle of laser therapy relies on the absorption of photonic energy by molecular photoacceptors (chromophores), leading to a photochemical reaction. This photochemical reaction results in the generation of Reactive Oxygen Species (ROS) and heat, which are known to play a crucial role in laser-induced damage. This study explores the role of specific heat in affecting laser-induced damage. By using the formula, H = msÃŽ ¸ (H being Heat, M being Mass; S being Specific heat, and ÃŽ ¸ being change in temperature), it was speculated that a change in specific heat would affect rise in temperature and hence cytotoxicity induced by the laser. Therefore, the specific heat of different solutions was measured using a calorimeter-like setup. Once the specific heat of different solutions was determined, cells (HaCaT, Human Skin Epithelial Cells and NOKSI, Normal Oral Keratinocytes) were treated with solutions of varying specific heat capacities and assessed in laser damage. It was observed that in lowering the specific heat by using various cell culture solutions, there is a sharp increase in temperature at lower laser doses, leading to increased damage to cells. Further, a robotic arm is being assembled to characterize the heat dispersion during clinical therapy, with the aim of mimicking manual operator hand motions and helping simulate clinical therapy in further lab experiments. INTRODUCTION There are three primary phases of wound healing—inflammation, tissue formation, and tissue regeneration. It is a dynamic, interactive process involving soluble mediators, blood cells, extracellular matrix, and parenchymal cel... ...of glycerol is indeed cytotoxic. When treating the cells with a 1.7W laser, the 10% FBS solution proved to be the most effective in preserving cell viability, due to its high specific heat capacity. Future goals of this experiment will strive to determine whether the laser-induced killing is through heat, Reactive Oxygen Species (ROS) generation, or some other factor. In Aim 2, we were able to capture the precise clinical operator movements in multiple dimensions using the precision 6-axis sensor. We recently completed construction of our robotic arm and are in the process of programming using the clinical data captured with the sensor. This robotic arm concept is expected to greatly stabilize the laser motions, and will certainly be a beneficial and revolutionary application in not only lab experiments, but also experiments dealing with animals, such as mice.

Being a Man: Rhetorical Analysis

Being a Man, by Paul Theroux, delineates the negative effects of being a man According to himself. Theroux, in his piece, argues that a man is oppressed by gender expectations, despite living in a society where women are belittled in comparison to men. Theroux attempts to explain the gap between genders which cause bad marriages, social misfits, moral degenerates, sadists, and latent rapists. Theroux proposes that the idea of manhood in America has caused some men to feel like they dislike being a men, and caused them to reject part of their own identity deep down inside.His overall purpose it to bring awareness to both genders that an oppression is happening to American society due to gender. Theroux tries to create understanding between the two opposing genders and find common ground against the same type of oppression both genders face, â€Å"This version of masculinity is a little like having to wear an ill-fitting coat for one’s entire life (by contrast, I imagine femini nity to be an oppressive sense of nakedness)†.Theroux uses parenthetical comments in order to widen the range of theme to his essay. He not only writes about man, but about women to and how they both have become affected by the gender constructs put in place from living in an American society. This allows his target audience (both men and women) to become understanding of his purpose in the essay. Not only are men able to relate, but women to as they are remembered in the fact that they face the same oppression as the one described by Theroux.This rhetorical effect is repeated to reemphasize Theroux’s purpose, â€Å"(The paradox in American letters is that it has always been easier for a woman to write and for a man to be published)† Theroux is able to not only give the message that the gender constructs oppresses only men, but also women, gender in general for that matter. Theroux is able to successfully convey his message (to both genders) that this society is harmful to both genders. Theroux appeals to the audience’s sense of emotion as he applies his arguments soundly to gender oppression, an emotion felt with both members to his target audience.His argument is that gender constructs lead to an oppression that leaves one feeling a displeasure with their own identity. This feeling of self-loathing appeals to people’s sense of emotion. This appeal allows the readers to engage and relate, which captivates them into realizing Theroux’s message. Theroux is effective in his proper use of pathos without having to consult much with the author branches of persuasion, credibility and logic. Personally I am not able to relate much with the American gender construct. Seeing as I was raised in a more Mexican household, I was raised to believe in a stricter gender construct.One that doesn’t apply much to Theroux’s description of the male gender construct setup by American society. Mine has roots in a one that emphas izes absolute respect for women and realizing that her body is nothing less than sacred. You’d think that this would be a better way of thinking, but this kind of thinking still implies that a woman is in need of more respect, which creates a kind of sexual inequality. Although making sense and persuading me in his argument, I was not able to relate to his argument, which was part of his purpose.

Startups in Publishing †IPR License

Startups in Publishing – IPR License Startups in Publishing – IPR License What’s the â€Å"publishing industry†, really? It’s a mixture of a lot of companies, big and small, that all revolve around authors, books and readers. The big ones have been shaken by the digital disruption and are only now realizing the truth of â€Å"adapt or die†. And because they’re big, this will now obviously take time, as Hugh Howey recently pointed out (quite accurately).That’s where the smaller cogs in the wheel come in–and I’m going to say â€Å"we†, as Reedsy is a part of the machine, and I’m a part of Reedsy. Since the digital disruption, the landscape of publishing has become a fabulous playing ground for many startups. So many, in fact, that I hear this question a lot when presenting Reedsy: â€Å"Do you really think we need yet another self-publishing/digital publishing company?†My answer is usually a version of: â€Å"Are you satisfied by the current state of this industry? Do you think ind ependent publishing has now been made a simple process? Do you think we’ve all finally, fully embraced the digital disruption?† I dare you to say yes.Here at Reedsy, we’re big fans of all the little ships that enter the vast ocean of book publishing with the certainty that they will make a difference. We believe they will be the ones fashioning the future of the industry and turning it into something coherent and adapted to these modern, digital times.To celebrate them, we have decided to create a serial on startups that we will be publishing every Monday on this blog. These are all startups actually providing fantastic value to authors, and which we believe will play an important role in the future of publishing. For this reason, they are all startups that Reedsy is or will be partnering with in the near future.Today, we start with IPR License, the first and only online platform on which to acquire subsidiary book rights and permissions on a global scale. It was founded by Tom Chalmers back in 2012 and has greatly grown since. Read our interview with Tom below.RF: Why did you start IPR? What’s the founder’s story?Tom Chalmers: I founded my first publishing company in 2005, Legend Press, and with only a borrowed computer and no experience or contacts I licensed the second novel into seven editions and four languages. Five further companies were started between then and 2012, when the idea of licensing potential that had stayed with me since 2005 came to the fore. That led to my seventh company, IPR LIcense, the global rights licensing platform.RF: That’s great! I actually was at Frankfurt Book Fair, and felt it was more mess than â€Å"Messe†Ã¢â‚¬ ¦ So I can understand the need for an online platform for trading rights, but how quick do you think big publishers can be to switch from a meeting-at-book-fairs model to an online one? Is your ambition to replace big international fairs or to complement them?TC: Itâ₠¬â„¢s not a case of switching from face-to-face meetings–publishing will always be a subjective and personable industry–but complementing them. Book fairs are now hubs of business and not the only place to do business, which does mean a smaller but more focused footfall.Technology not only means business can be completed 24 hours a day seven days a week, all year round, but at the book fair as well. We see a time shortly where meetings can be held and interested parties can then complete the deals immediately rather than waiting for the two-weeks-later follow-up.RF: What rights are most acquired by publishers on IPR License (digital, print, foreign, Film/TV, etc.)?TC: It is hard say as we have over 13 million titles on the platform, not only books but journals, manuscripts and screenplays too. The obvious focus is on print and in particular translations where there is huge potential, but we also see lots of for instance audio, large print and production materials deals being completed as well. The book is a single entity of intellectual property, one of many that can potentially be licensed.RF: How active are you in the negotiations and contracting that follow after a publisher has singled out a book whose rights they are interested in?TC: As much as the member would like us to be. In general we are a technology solution to allow the seller and buyer to directly complete deals. But we also have a team to help facilitate the transactions, so if a seller says they want a bit of help in the negotiation or contract and so on, we will provide that for them.RF: I think that’s great. It’s important to keep this individual approach to every single client even if you have a scalable model. Now over to the revenue stream; what’s your business model?TC: We charge a flat annual fee of  £99 for authors and a fee for publishers dependent on company turnover. We then take 15% commission from deals completed via the platform.When you join IPR License, you don’t only have access to market-leading technology but account management, licensing and marketing support. We usually say the annual fee is the equivalent to the fee from a single deal completed, a lot less for authors, so the risk is not unreasonable.RF: Now here’s something I’ve always been curious about: Some say indie authors start out self-publishing specifically in the hope of getting discovered by a traditional publisher. But on the other hand, you get the numerous stories of traditionally published authors switching to self-publishing as soon as their contracts end (or even sooner). From what you’ve seen at IPR, which wave is bigger: indie to trad or trad to indie? Or do you see a hybrid model becoming the norm?TC: We’ve seen a self-published author, Mary Wood, received a seven-book deal from Pan Macmillan and we have many authors who have reverted the rights from publishers and are looking to license them directly. Weâ⠂¬â„¢re not really focused on or interested in the trend, which I imagine is changeable anyway; we’re solely focused on helping the rights owner, whether an author, publisher or agent, license their valuable IP to third parties around the world.RF: What would be your top advice to self-publishing authors looking to sell their print or foreign rights? In other words, what do publishers look for on IPR License?TC: Get the basics rights: how the book is listed, what categories to use, what content to use to support the potential purchase of the rights, ensuring the correct sales and rights information is listed and so on. Also, making sure the key books are listed as key books as they are then prioritised in the search engine.RF: How should indie authors be using IPR? Should they be listing a particular kind of title? Or is the benefit of an open directory like IPR that even niche works can find an audience, and so all works ought to be listed?TC: We try to be as open as possibl e and we see licensing deals being completed for works completely across the spectrum. As well as getting the basics rights, as per above, I would also say to take a back step and think honestly about where the work may appeal and to tailor the listing details accordingly. A lot of authors say â€Å"perfect for film† or â€Å"should be big in the US† etc., but the most successful ones have a basic understanding of the markets and a realistic view of where the work will appeal.RF: You launched Rights Magazine last year to coincide with the five biggest international book fairs in 2014. What’s its content and who is it distributed to? Why a magazine?TC: It contains editorial, company news, publisher and author profiles and highlighted titles, etc. We have a market-leading technology platform but we also want to provide as much visibility and marketing for our members as possible and the magazine has been a very successful way of achieving that. It is distributed i n different ways at each book fair and is part of a wider promotional plan at each event.RF: From founder to founder, how do you see IPR License and Reedsy working together? What value would Reedsy add to IPR License (and its authors)?TC: I think two ambitious start-ups looking to be at the forefront of the market should have natural synergies, whether that means providing joint services, education or other forms of partnership, so I look forward to a long period of working together and discovering what can be offered to each other’s customers to improve their experience.RF: Easy one to finish: How do you envision IPR License in 5 years? Do you have any major milestones you plan to hit on the way?TC: Our plan is to be the industry standard tool for finding and transacting rights business. We are confident that will happen over the next 12 months, so saying where we’ll be in five years would sound far too grand.RF: Thank you for your time, Tom!Post edited by our lovely editor Becca!Find us on Twitter: Reedsy, IPR License, Tom Chalmers and Ricardo

Forest Ecosystem and Biodiversity Definitions

Forest Ecosystem and Biodiversity Definitions A forest ecosystem is the basic ecologic unit in a particular forest that exists as home for a community of both native and introduced classified organisms.  A  forest ecosystem is  named for the primary tree species that form the canopy. It is defined  by all the collective living inhabitants of that forest ecosystem that co-exist together in symbiosis to create a unique ecology.   In other words, a forest ecosystem is typically associated with land masses covered in trees and those trees are often  classified by foresters into  forest cover types. Examples of just a few  broad names in North America are The northern hardwood ecosystem, the ponderosa pine ecosystem, the bottomland hardwood  forest ecosystem, the jack pine forest ecosystem and so on. The forest ecosystem is just one of a number of unique ecosystems including prairies, deserts, polar regions, and great oceans, smaller lakes, and rivers. Forest Ecology and Biodiversity The word ecology comes from the Greek oikos, meaning household or place to live. These ecosystems or communities are usually self-sustaining. The word usually is used because some of these communities can become unbalanced very quickly when detrimental factors occur. Some ecosystems, like tundra, coral reefs, wetlands, and grasslands are very fragile and very small changes can affect their health. Larger ecosystems with wide diversity are much more stable and somewhat resistant to harmful changes. A forest ecosystem community is directly related to species diversity. Generally, you can assume that the more complex the structure, the greater is its species diversity. You should remember that a forest community is much more than just the sum of its trees. A forest is a system that supports interacting units including trees, soil, insects, animals, and man. How a Forest Ecosystem Matures Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving  toward an old growth forest. When an ecosystem is exploited and exploitation is maintained or when components of the forest begin to naturally die, then that maturing forest ecosystem goes into declining tree health. Management of forests for sustainability is desirable when forest diversity is threatened by overuse, resource exploitation, old age, and poor management. Forest ecosystems can be disrupted and harmed when not properly sustained. A sustained forest that is certified by a qualified certification program gives some assurance that the forest is managed to allow maximum diversity while satisfying the managers environmental and economic demands. Scientists and foresters have dedicated their entire careers trying to understand even a small part of forest ecosystems. Complex forest ecosystems are extremely diverse, ranging from dry desert shrub land to large temperate rain forests. These natural resource professionals have categorized forest ecosystems in North America by placing them into forest biomes. Forest biomes are broad categories of natural tree/plant communities.

Homeland Security and Terrorism Term Paper Example | Topics and Well Written Essays - 1500 words

Homeland Security and Terrorism - Term Paper Example Terrorism is a global problem and the emergence of terrorists groups is a threat to the international security. The Islamic state of Iraq and Syria (ISIS) is known by many individuals worldwide following its brutal actions and violent tactics in an effort to establish Islamic state in Iraq, Syria and beyond. ISIS is a major threat to America because it has a territorial base, which makes it easy for them to plan and organize terrorism against the U.S. More so, ISIS recruits American citizens who have travelled to Syria and Iraq to support them and help them fight, and this makes them dangerous and able to commit acts of violence upon their return. This paper explores the Islamic state of Iraq and Syria as one of the major terrorist groups threatening America. It also covers new homeland policy designated to prevent and respond to terrorism and protect citizens. The Islamic State of Iraq and Syria (ISIS)The Islamic state of Iraq and Syria, also known as ISIL, is a rebel group that is popular worldwide because of its violent tactics to create a caliphate. This group is based in Iraq and Syria in the Middle East and its major aim is to establish an Islamic state in majority regions of Iraq and other Muslim-inhabited regions worldwide. This group claims religious authority over all Muslims globally and have absolute control over Islamic states. The United Nations and many countries have recognized the ISIS as a terrorist organization because of its violation of human rights.
