Steel scalpel vs obsidian scalpel2/19/2023 ![]() ![]() TL DR, The internet is a scary place make sure you know that cited information is correct.Īlso - I'm a chemist, not a field expert and this should be taken with a grain of salt and not as god's honest truth. Here is a screen grab of some micrographs. 1993 and see that with proper procedure, the sharpness of the blade doesn't actually matter that much anyhow (s'far as the average Joe is concerned).ĭigging deeper, you check out the Wikipedia article on obsidian and find Ancient Technology in Contemporary Surgery, 1982 and see that it suggests results contrary to the other article. You'll quickly find A comparison of obsidian and surgical steel scalpel wound healing in rats. When you then go searching for this article - I've only given it 10 minutes, to be fair - you have extreme difficulty finding science to back it up. For instance, because of how sharp they can be, obsidian scalpels cause much less trauma to flesh that they slice through, resulting in faster healing. In fact, despite a lack of FDA approval, some surgeons routinely use obsidian scalpels as they have some significant advantages over their steel counterparts. You find that it is posted on the internet several thousand times with this same text. An obsidian blade can hold an edge of just 30 angstroms, making it sharper than any modern scalpel. The surgical tools they used were made from bronze and shaped obsidian.ĭespite the fact that obsidian is a very popular material used for mirrors, decorations, and even bogus energy trapping, the glass’ main use nowadays is still as a cutting tool.This citation seems like a real citation.until you google it. ![]() These ancient doctors used brain surgery to treat a variety of diseases like mental illnesses, epilepsy, headaches, organic diseases, neuropathy treatment, osteomylitis, and head injuries. with an inordinate success rate noted among patients, archaeologists say. The Pre-Incan civilization used brain surgery as an extensive practice as early as 2,000 B.C. Map showing the locations of some of the main obsidian sources in Mesoamerica. The latter possibility means that our species is at least 85,000 older than we believe. These spears were made from obsidian by either another species - which had to be extremely crafty and clever - or ancient humans. The remains are so ancient that they actually predate the earliest known fossils of our species by 85,000 years. Remarkably, obsidian tools may even predate humans! Researchers have found what they believe to be the oldest known stone-tipped throwing spears. At 42 days, all wounds were barely detectable, thus precluding scar width analysis. At 21 days, scar width was not different in the two groups. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days (p < 0.005). Ancients may have transported these goods thousands of miles to trade for other goods and services. Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. Historians believe obsidian may have been the very first material actively mined and used to manufacture sharp tools at scale. ![]() The colors are thought to be caused mainly by trace elements of inclusions. Rarely, obsidian can be blue, red, orange, or yellow. However, it can also be brown, tan, or green. All sorts of prehistoric artifacts made from obsidian have been found by archeologists, including knives, arrowheads, spear points, and scrapers.īlack is the most common color of obsidian. Over time, ancient peoples learned to break obsidian into tools of various shapes. This means the obsidian breaks into pieces with curved surfaces that are razor thin and extremely sharp. The volcanic glass is thought to be so sharp because of the way it breaks, a pattern geologists call a conchoidal fracture. ![]() “It is in this manner: First they get out a knife stone (obsidian core) which is black like jet and 20 cm or slightly less in length, and they make it cylindrical and as thick as the calf of the leg, and they place the stone between the feet, and with a stick apply force to the edges of the stone, and at every push they give a little knife springs off with its edges like those of a razor.” Hester et al. Motolinia, a 16th-century Spanish observer, left this account of prismatic blade production: “The prismatic glass blade is infinitely sharper than a honed steel edge, and these blades can be produced in a wide variety of shapes and sizes,” wrote Bruce A. Don Crabtree who re-discovered the production technique in the 1970s. The finest of these prismatic blades were produced in Mesoamerica about 2,500 years ago, according to Dr. ![]()

Ultimate spelling 20152/19/2023 ![]() ![]() The learner is immediately immersed in a well-rounded learning experience. Unlike most spelling programs that have a narrow focus only on the spelling of words, eReflect’s Ultimate Spelling™ offers a complete approach to literacy improvement. The reviewer highlights that the software's activities and learning methodology is based on proven principles that are grounded in thorough research, something that makes it a trustworthy solution for parents looking for a fun and efficient way for teaching spelling to their children.ĮReflect is honored to have its spelling software recognized for its efficiency in promoting orthography skills in children and adults. "One of the great points about Ultimate Spelling is that it has been developed to make spelling fun, rather than a drag, for children.” “Ultimate Spelling is streets ahead of older products when it comes to spelling improvement (especially for children)," he notes. The editor at Software Boffin uses his in-depth review of the spelling software to explain exactly why it’s worthy of first place and Boffin’s 5-star rating. Software Boffin has previously evaluated earlier versions of the program, and this year they confirm their previous ratings, asserting that Ultimate Spelling™ is the go-to solution for teaching spelling. Ultimate Spelling™ 2015 is the latest release of the industry-leading program by eReflect that teaches people how to spell.

Now a senior at Poly, Tayler is looking at Hood, Fordham, and Penn State. Clair Nytiece Powell Malia Carter Phillip Freeland Tayler was one of our very first students, joining SquashWise in 7th grade. SquashWise students attend a variety of middle schools and high schools in Baltimore City, including ACCE, KIPP, Waverly, Poly, City, Western, Mervo, ConneXions, and Cristo Rey. Sincerely, Sage Platt Board Chair Abby Markoe Executive Directorģ 4 Meet Our Students We could not be prouder of our students! Through their hard work on and off the court, they earn incredible opportunities to travel and compete nationwide. We look forward to continuing to partner with you in our successes for many years to come. We cannot thank you enough for your generosity and commitment to our family. It is with your invaluable support that our students are able to access incredible opportunities that will set them on the path to success. Through years of academic tutoring and enrichment, college visits, and social support, these students are ready to take what they have learned with SquashWise and make their own futures. Students will move on to college and career placements more prepared, more confident, and knowing that SquashWise will continue to support them. This year will be a milestone for us with our first cohort graduating this coming spring. Today, with you, our extended family, we are celebrating six full years of impactful work in Baltimore City, proving that the combination of academics, athletics, and mentoring will change a child s life. Our students dedicate many years to SquashWise from the start of middle school, through high school, and then beyond into college and careers. They have also learned the importance of having strong character and demonstrating commitment to their teammates. Through the years our family has grown and our students have learned the value of studying hard, training year-round, and competing across the country. Their motivation and effort during tryouts secured them a spot on our team, as well as a place in what would become a second family. Many of these students had no opportunities to be a part of team or travel outside of Baltimore. To the SquashWise Family: Six years ago, SquashWise held tryouts for a group of enthusiastic students who had never heard of squash, but had the desire to try something new. We develop committed scholar-athletes through a long-term program of academic tutoring, college/career preparation, mentoring, squash coaching, and fitness training. 2 2 Training for Squash, Training for Life Welcome Letter SquashWise is not your average sports team. ![]() Sonority definition2/19/2023 ![]() Consequently, violence becomes widespread across society: conflict is more a medium through which the contradictions and hierarchies that structure it are inscribed and staged than a feature of the contexts into which such practices are inserted. Such a connection between sound and violence shows that the sounds addressed here make public violence diffuse, even if unequally distributed, as agents are both its victims and perpetrators. After all, boundaries are built one learns to listen to the place with its vibratory particularities, and strategies are devised to conquer space, to maintain it, or to take it from potential opponents who seek to usurp it. ![]() ![]() ![]() Territorial dynamics are, therefore, intrinsically violent because they imply the occupation of space by social agents against the resistance of others. In that context, the boundaries historically delimited by sonic battles are maintained because the community demonstrates the power necessary to reaffirm not only its religious, but especially its sonic, practices in counterpoint to the imposed silence. This sonic “Holy War” contrasts the public and the private, the street and the temple, loud and soft sonorities, and impels the continuous (re-)establishment of symbolic landmarks of place. The acoustic territory of the Santa Marta neighborhood is shaped, disputed, and retaken by the sound of Banda de Congo Amores da Lua through the social and cultural dynamics presented so far. This is the aspect we emphasize when talking about the relations between territorialities and sonorities. Yet, besides being dominated, territory is also a “lived-space-time” (Haesbaert 2006: 2), appropriated and disputed by several co-present and conflicting social dynamics (Haesbaert and Limonad 2007: 42-43). Daughtry assumes that a territory is a conquered space, “a place whose identity is maintained by force or threat of force” (2015: 125). What we try to outline here are the social disputes over the ownership of place that use music and sound not only to delimit spatial boundaries but also to broaden them or to express a local resilience of peripheral groups against actions that aim to silence or domesticate them. Brandon LaBelle’s definition of acoustic territory, which focuses on “movements between and among different forces” (2010: xxv), or Giuliano Obici’s (2006) term sound territory, which deals with the construction of borders and the attribution of qualities to the audible, also do not address these issues. ![]() They also refer to buildings and their absorbing or reflective characteristics within constantly changing environments that mediate, modify, or enclose sounds in a given time-space.Īlthough the possibilities outlined by the term acoustic territories seem to be of great power for understanding a series of processes that relate sound and space, it seems to us that Daughtry leaves an important aspect of the discussion regarding territoriality phenomena in the background, one that is of great importance to the issues we intend to address here. For Daughtry, the acoustic territories are linked, then, to the borders constituted by sound and listening. Thus, the notion delineates the ways in which sonorities are capable of inserting/removing individuals and their bodies in/from a geographical externality in which they are located and in/from the biological internality that regulates their lives as well as transporting them to different symbolic places, according to how the same sonority can refer to different social and cultural codes that relate to various situations. 197 unscramble word found using the letters sonority.The third term Daughtry introduces, acoustic territories points to “the ways in which our understanding of the places in which we live and move is structured in part by reverberating sounds and acts of listening” (Daughtry 2015: 126). ![]() Squirrel call2/19/2023 ![]() Within SQUIRREL we will port the intermediate results from the scientific work packages to our second demonstrator platform Care-O-bot 4 in order to assess reusability of the developed components.

Since when does that work? Just because you’re on chat it does not mean you can deny the situation. Meanwhile, the person receiving is probably going: “wtf is their problem” and, really, what is our problem? Why do we think that sending a simple heart will cure anything? The Totally-Out-of-Context HeartĪnother very practical way to use the heart emoji is when it makes no sense at all. Although, deep inside, you know it won’t solve the conflict, at least you don’t have to deal with it at that moment. Why explain yourself when you can just send a heart emoji and send them so much love they can’t be angry anymore. ![]() You receive a text, someone found out you’ve been lazy or done something cheeky, and calls you out on it. Here is another one I catch myself doing all the time, especially in texts to my mom (sorry, mom). Why can’t we just say bye? I swear saying bye isn’t awkward. But are you really? That would never work in the non-cyberspace world, because conversations don’t just end in hearts. Send a cheeky heart, get one back, and you’re, once again, saved from awkwardness. So, before it gets awkward, you quickly consult the panacea of all emojis. You’re talking to your best friend, you’ve finally agreed on what to do – after debating for a good 20 minutes via passive aggressive messages – and then, after both writing “omg can’t wait, I’m so excited” you’re kind of stuck in that weird time in space where you’re having an ongoing conversation but there’s still time before meeting and you don’t have any idea what to say. ![]() Pixel 3 for honor2/19/2023 ![]() ![]() ![]() The dynamic range of images and videos is flexible and can be edited and used. and process human skin tones to match reality Front camera, resolution 12 MP (f/1.9), pixel size 1.36, micron, focal distance 23 mm.įrom both photography and video tests, the iPhone 14 Pro’s camera processing was found to be satisfactory, regardless of color intensity.Telephoto camera, 12MP resolution (f/1.78), 1.22 micron pixel size, 48mm focal length, 2nd generation OIS image stabilization.Ultrawide camera, 12MP resolution (f/2.2), 1.4 micron pixel size, 13 mm focal length, PDAF.Main camera: 48MP (f/1.78) resolution, 2.44 micron pixel size, 24mm focal distance, 2nd generation OIS image stabilization, Focus Pixel.but lost to Honor Magic4 Ultimate, which scored 147 points, leading by only 1 point 146 points (including still images + video) by coming 2nd Of all the mobile phones tested by DxOMARK.ĭivided into 143 points for still photography / 139 points for zoom / 149 points for video shooting, which is considered a high score. because he can score a total of until he comes up to 2nd place It will be second only to Honor Magic4 Ultimate.ĭxOMARK has compiled a summary of the results, with the iPhone 14 Pro scoring all camera performance.

Usually, participants will have a reasonable sense of what those are. Understanding problems to solve – or opportunities to explore – is the beginning of solution design. Knowing customer needs and blockers through deep research is best. When working high level during a workshop, it’s enough to know only the main things that get in their way. Those are Behavioural Archetypes! Example goals and actions of a customer buying an accountancy software product Map the barriers and missed opportunities Eventually, several kinds of customer will have been defined by their needs, behaviour and tasks. all kinds of students. Again, arrange similar items into clusters, and describe each with a name. For each group, take a few minutes and post-up all the common actions or tasks performed anyone that belongs to the parent group e.g. Example customer groups from a university faculty website design project Define goals and actions Then, come back to customer groups later. If the product is mass market – meaning that ‘everybody’ is a customer – you may get better outcomes by having participants define goals and actions first. Post-up all the suggested names, then cluster into meaningful groupings and give each group a name. These are later used for ‘mapping’ – to explore problems and opportunities for each group.

Good personas aren’t created in workshops. ![]() Good ones reveal insight from research in a way that humanises the design process. That can be useful, but business process mapping is a better tool for that. It’s a similar conundrum for Personas. People talk of how customers ought to interact, not how customers actually behave. With best intentions, discussion gravitates toward the business. When you’re working with folks that aren’t close to customers, using those methods is tedious and unhelpful. Research methods like Experience Mapping and Personas need a deep understanding of customers. It’s similar, but Experience Mapping is a research method, not a workshop activity
