5/11/2023 0 Comments Blood bowl team manager![]() These three teams are part of a new league, the Dark Sorcery Syndicate, and thus have their won star player deck to draw from. Sudden Death adds three new teams to the mix – the Naggaroth Nightmares (dark elves), Champions of Death (undead), and Black Fangs (vampires). After five round, the player with the most fans is the winner. After each player has committed as many cards as they can or want to (up to six), the power is added up and the winner gets a bonus payout (players usually get something just for showing up). You are trying to have the highest power on your side, and along the way you can use tackles, carrying the ball, drawing from your deck of cards, or cheating to gain an advantage. You commit your players to different highlights, which represent the games. This Spike! card could be a tournament or a headline that will change the rules a bit. In each round, there will be a number of highlights dealt into a row equal to the number of players, plus an additional Spike! magazine card. It’s played over five rounds culminating in the Blood Bowl Tournament. Blood Bowl Team Manager takes the Blood Bowl sport (as present in the Warhammer 40K universe) and puts it into a card game, where players are trying to build a team that will attract the most fans. There are also some new tokens that go with some of the new mechanisms of the game. It adds new teams to the base game experience, as well as new star players, new staff and team upgrades, new highlight cards, new headlines, and a new tournament. Sudden Death is the first expansion to Blood Bowl Team Manager, designed by Jason Little and published by Fantasy Flight Games.

Open the sheet, which is really opening the drawing file with that sheet layout active.Ĥ. The sheet name in the sheet list is simply a shortcut to that layout in the DWG file.ģ. This will create a new drawing file (DWG) with an active layout tab. Create a new sheet in the Sheet Set Manager. Try to forget that the layout tab even exists - this is your “model file.” From now on, let the “sheet file” deal with the layout.Ģ. In that particular DWG file, focus on nothing but the model. Continue to create model geometry in modelspace including xrefs, nested xrefs, etc. Create your model geometry in its own drawing file (DWG). You can accomplish more than half the process without changing your current workflow while enjoying significant productivity gains all along the way.īelow is a quick overview of how sheet sets are intended to work.ġ. If you have two sheets that point to different layouts within the same drawing, the drawing file will be locked as soon as one person opens one of those sheets, which is how AutoCAD has always worked.Įven if the intended process for implementing sheet sets deviates from your current workflow, don’t be deterred from using them. ![]() The main benefit for this is to enable multiple users to work on different sheets at the same time. There is no technical reason why you shouldn’t have multiple layouts in your drawing, however the new sheet set paradigm or “best practice” is to have one sheet drawing (DWG file) for each sheet in your set. If you have more than one layout in your drawing, you can import those additional layouts into your sheet list. The only technical limitation is that each sheet in the SSM sheet list can only point to one layout in a drawing file. You can draw geometry in model space, create additional layout tabs, etc. The drawing file created by the Sheet Set Manager is just like any drawing you create using traditional methods. Note: This excerpt was taken from “Mastering AutoCAD Sheet Sets” by Autodesk. After you successfully create a sheet set you can view your sheet set through the SSM Palette as shown in below on the right. Finally, for those of you who use the command prompt type SSM. If you use the menu bar (MENUBAR set to 1) you can find it under the file section also shown. ![]() The Sheet Set Manager (SSM) can be found on the ribbon under the application menu as shown in in the image below. With sheet sets you can have others on your team work on one subset while you work on another making collaboration and managing your design package an easy task. If you use sheet sets in the most basic way you are just taking drawing files and organizing them in proper order, so they can be easily accessed when working through your project. The AutoCAD Sheet Set Manager is a great tool to manage your drawings from start to finish in your design. All these aspects require preparation and good document and project organization. Any design project you work on requires a set of drawings and specifications to accompany the report which specifies the intent of the design. 5/10/2023 0 Comments Zip and rar for mac![]() Step 2: Drag the Keka app to the Applications folder and drop it there. Step 1: Download Keka on your Mac using the link above. However, we will be demonstrating the steps using Keka. If you’re looking for an alternative app that’s free on the App Store, check out The Unarchiver. The Mac App Store version requires you to pay for it and if you really like what Keka does, we suggest you pay to reward the developer’s efforts. Keka is a free app and you can download it from the developer’s website. You will have to download a third-party app like Keka. How to Open RAR Files Using KekaĪs mentioned earlier, there’s unfortunately no native way of opening RAR files on a Mac. Mac lets you do that using a third-party app or an online tool. So you’ll need to uncompress or un-RAR those files to view the contents packed inside. As a result, some files you find online or get as email attachments could be compressed into a RAR file. RAR files are useful if you want to reduce the size of a bunch of files before sending them. Think of it as a ZIP file but with higher levels of compression. A typical RAR file consists of one or several compressed files bundled together. Just like the ZIP file, which is actually an archive file type, RAR file works similar but offers a bit more features. If you’ve downloaded an attachment or received a link to download documents in a RAR file, here’s how you can open it on your Mac. While there are several apps on the App Store for the job, we’ve picked the one that’s simple and easy to use for opening RAR files on your Mac. 5/10/2023 0 Comments Home depot vinyl flooring![]() Depending on your wear layer, your floor has likely received a surface treatment (specific to the manufacturer) that helps make it resistant to scratches and stains. Vinyl flooring-particularly high-quality vinyl flooring-is easy to maintain. In some cases, high-quality vinyl can approach the cost of inexpensive hardwood, so be sure to compare and contrast between the two before making a final decision. As with most types of flooring, you will pay more for a high-quality and customized floor. A good range to ballpark for quality vinyl would be between $2.50 to $5.00. Vinyl can cost anywhere from $0.50 per square foot for a sheet to $5.00 per square foot for luxury planks or tiles. If this is a concern for you, we recommend avoiding high-VOC vinyl flooring and choosing a low-VOC floor instead. Off-gassed VOCs can adversely affect health and an indoor environment, particularly without windows or ventilation, will lead to higher concentrations. Manufacturing vinyl flooring requires the use of toxic chemicals, and after installation, vinyl floors have been known to emit VOCs (volatile organic compounds). Low-quality vinyl floors, especially older floors, may even have a negative impact. Most of the time (though not always) vinyl floors do not have an impact on the resale value of a house or building. This is especially true for sheet vinyl or low-quality vinyl. Once the floor is damaged, the affected areas, or the entire floor, must be entirely replaced. Since vinyl flooring consists of a single wear layer over the design layer, it cannot be refinished. The Cons of Vinyl Flooring Cannot be refinished Vinyl is quite affordable and has an uncomplicated installation process that can be DIYed fairly easily. Vinyl can also have soundproofing qualities, which serve to reduce both noise and echo in any room. These layers also insulate and help the floor maintain a consistent temperature no matter the season. ComfortableĬompared to materials like hardwood or stone, vinyl flooring has a “softer” and more “padded” feeling underfoot, thanks to its layered composition. Some brands manufacture 100% waterproof vinyl floors-excellent for bathrooms or mudrooms. If it has a wear layer, vinyl flooring will usually not stain and can survive plenty of wear and tear, which makes it a good option for any highly trafficked areas. This means that most vinyl flooring is water-resistant and very low maintenance, with long-lasting durability. Vinyl flooring is known for being resilient. A top wear layer of varying thickness protects the sublayers from damage. Over this is an image layer, which can mimic a multitude of materials including wood and ceramic. A core layer, potentially with an underlay or backing, makes up the bulk of the floor. ![]() Made from materials like plastic, fiberglass and PVC, vinyl flooring typically comes in planks, tiles or sheets that can then be assembled. Vinyl flooring is a type of multi-layered synthetic flooring.

Now with the streaming, we’re streaming a lot. It’s incredible, and I’m lucky that the band I was in keep coming back on a daily basis, because the kids, every generation, still discover the Beatles. It all comes back - music just travels through time. Only like 18 months ago did I finally take the cassette player out of the system! But now the cassette is back - it’s next to the vinyl player. I only heard it, so you must know more than me because you work for the music paper. I heard this incredible story that the kids are back into cassettes. It’s a five-track EP, and I know what EPs are. New Year’s Eve, they’ll all sing along with us, we hope. I just thought it was so relevant to the days we’re living in right now. The record is called Zoom In, because we’re on Zoom. You have more energy than any 10 people put together. That helped - I made a record and did some painting.Īmazing. And it gave me a couple of miserable days, because I want to play. I was disappointed that the pandemic got in the way of my two tours this year. Who knew what this pandemic meant? We have got it on for next year, but we’ll have to wait and see. I want to go out on the road.” The first tour was May, but we didn’t cancel until March. Everybody’s moaning like me, “We want to go out. I would still be out there, but I’m afraid nobody’s out there. Until the pandemic, you’d been on tour non-stop all these years. Lenny Kravitz came on at the last minute. Dave Grohl, and Ben Harper were the first ones up. Joe Walsh, Sheryl Crow, Jenny Lewis, Chris Stapleton, Benmont Tench. And we’ve all had them with friends we won’t forget.Īll these people joined in and helped me out. Everybody I know, we’ve all had quite a few nights we don’t remember. It’s about us all coming together, so it seems appropriate for today. How did that happen?ĭiane Warren wrote it: “Here’s to the nights we won’t remember, with the friends we won’t forget.” So it has a beautiful sentiment. As Ringo says, “New Year’s Eve, they’ll all sing along with us, we hope.”Ĭongratulations on the new song. “Here’s to the Nights” is a wry sing-along with lyrics from Diane Warren. But as he always warned us, it don’t come easy. For one of rock & roll’s most beloved figures - and one of its most gregarious legends - it was a challenge to adapt to making music in the age of social distancing. Ringo worked in his home studio on a five-track EP set for March, with the timely title Zoom In. He got a little help from his friends for “Here’s to the Nights.” The song has long-distance vocals from pals like Dave Grohl, Lenny Kravitz, Sheryl Crow, Chris Stapleton, Ben Harper, Ringo’s brother-in-law Joe Walsh, and many more - including a promising British bass player named Paul McCartney. His new single, “Here’s to the Nights,” is a quintessential Ringo ode to peace and love, just in time to sing out the end of a 2020 where everybody had a hard year. The Beatle drummer kept busy making music this year, even though it was the first time in years he couldn’t hit the road with his long-running All-Starr Band. I love my fans and they love me and it’s going to be wonderful to be peace and loving and playing for them again.Ringo Starr might have just turned 80, but he can’t be accused of taking it easy. ![]() Making music in the studio has been great, and it certainly saved me during the pandemic, but nothing beats playing live with great musicians in front of an audience. “This is the longest I’ve been off the road in years - up until 2020 I was touring every year with the All Starrs - and I’ve really missed it. “I can’t wait to get back out on the road and play,” Starr said in a statement. ![]() were originally slated to tour in 20, although both runs were postponed because of the pandemic. Complete information is available on Starr’s website.įor the 2022 tour, the All Starr Band lineup will boast regulars Steve Lukather, Colin Hay, Warren Ham, Gregg Bissonette, and Hamish Stuart, while the group will also welcome back previous collaborator Edgar Winter. The run wraps on June 26 at Ruth Eckerd Hall in Clearwater, Florida. From there, Starr will make his way around the East Coast - including three nights at the Beacon Theatre in New York City - then down south. The trek is set to launch with two nights at the Casino Rama in Rama, Ontario, May 27 and 28. After two delays, Ringo Starr will finally launch his tour with his All Starr Band this spring. 5/10/2023 0 Comments Farsky bata sizeThe oral jaws are generally highly movable and protru-sible, and tooth shape varies greatly, although most Neotropical cichlids have simple, subconical, unicuspid teeth, whereas African cichlids commonly have laterally bicuspid or tricuspid oral teeth. There is considerable variation in the shape of the toothplates and associated dentition, reflecting diet specializations. The unpaired lower pharyngeal toothplate and the opposed upper pharyngeal tooth plates are contained in a muscular sling characterizing labroid fishes. Cichlid diversity has been explained both by their advanced brood care and by the versatile design of the pharyngeal jaw complex used for food mastication. The presence of short paired hypapophyses on the third and/or fourth vertebral centra (Kullander, 1998). The sagitta features an anterocaudal pseudocolliculum having a long and thick ventral part which is separated from the crista inferior by a long, deep and sharp furrow (Gaemers, 1985) 9.

The presence of an expanded head of each fourth epibranchial bone (Stiassny, 1981) 4. The presence of an extensive cartilaginous cap on the anterior margin of each second epibranchial bone (Stiassny, 1981) 3. The loss of a major structural association between parts A2 and Aw of the adductor mandibulae muscle and the muscu-lous insertion of a large ventral section of A2 onto the posterior border of the ascending process of the anguloarticular (Stiassny, 1981) 2. Cichlids are recognized by several unambiguous anatomical synapomorphies. Crenicichla species are known as jacundá in Brazil, añashúa in Peru, angoumot (French Guiana), mataguaro (Colombia, Venezuela), datra fisi (Surinam), cabeza amarga (Argentina and Uruguay). Cichla species are known locally as pavón (Venezuela, Colombia) or tucunaré (Brazil, Peru), the latter name expressed as lukanani (Guyana), toekoenali (Surinam), toukounaré (French Guiana) or similar names in the Guianas. Higher level names include bujurqui (Peru, most cichlids), acará (Brazil, most cichlids), mochoroca (Venezuela), mojarra (Ecuador, Colombia, throughout Central America), krobia (Surinam), prapra (French Guiana). ![]() Cichlids are known by family or genus-level local names, commonly with an adjective to distinguish well-marked species. The geographical distribution includes freshwaters of Africa (900 valid species, estimated more than 1300 species), the Jordan Valley in the Middle East (four species), Iran (one species), southern India and Sri Lanka (three species, also in brackish water), Madagascar (17 valid species, some also in brackish water), Cuba and Hispaniola (four valid species, some in brackish water), North America and isthmian Central America (111 valid species), and South America (291 valid species) (Kullander, 1998, updated). The cichlids are the most species-rich non-Ostariophysan fish family in freshwaters worldwide, and one of the major vertebrate families, with at least 1300 species and with estimates approaching 1900 species (Kullander, 1998). 5/10/2023 0 Comments H2s molecular geometry![]() It has been suggested that healthy properties of garlic may be due to H 2S when crushed garlic is added to red blood cells H 2S is released, and it is known to act as a vasodilator, opening blood vessels. This suspended-animation state may be suitable for surgical applications. Very low doses of it can reduce metabolic rate, and it has been suggested that this could allow organ function to continue even when oxygen supply is limited, after a traumatic injury, for example. Yes, but there may just be medical uses for H 2S. This in turn led to oceanic bacteria reducing sulphate to produce large amounts of H 2S, killing aqueous plants and animals, both in the oceans and on land. The eruption of Siberian volcanoes led to large amounts of volcanic CO 2, leading to warming that depleted oceanic oxygen levels. It's been suggested that H 2S was responsible for a huge mass extinction of life about 250 million years ago, the "Permian-Triassic extinction event". Right: Warning sign from Germany, which says "No ice-skating - danger of life - hydrogen sulphide in the water". Left: Warning sign to wear a gas-mask in enclosed spaces if H 2S is present. The celebrated Bogle-Chandler case - the mysterious deaths of Dr Gilbert Bogle and Mrs Margaret Chandler on a Sydney riverbank in 1963 - has recently been attributed to H 2S released from the Lane Cove River. H 2S is denser than air, and can accumulate in the bottom of unventilated spaces, such as sewers. Inhibition of cytochrome c oxidase in a similar manner to HCN has been suggested as a reason for its toxicity, but others believe that it could also involve a reactive S-containing species which depletes glutathione and activates oxygen.Īpart from people working with "sour gas" fields of natural gas, sewage workers are particularly at risk, as stagnant sewage can release large amounts of H 2S when agitated, and fatalities are regularly reported. Taken together, this means that a person exposed to high concentrations may get no warning. At 500 ppm, inhalation can cause immediate collapse and unconsciousness, whilst one breath at the 1000 ppm level results in immediate loss of consciousness, cardiac arrest and death. Levels around 150-250 ppm cause the sense of smell to disappear, and slightly higher levels may well be fatal. It can be detected by its "bad egg" smell at levels around 0.005 ppm (parts per million). Surprisingly toxic, roughly comparable to hydrogen cyanide. These two gases react together in a redox reaction, forming sulphur, which can often be seen as a yellow deposit round the crater of a volcano (see photo, right).Ģ H 2S (g) + SO 2 (g) 3S (s) + 2 H 2O (g) How toxic is hydrogen sulphide? ![]() Volcanoes emit sulphur mainly in the form of sulphur dioxide, but some hydrogen sulphide is released too this is why the smell of volcanoes is mainly that of SO 2 ("burning match") rather than bad eggs. 64,000 residents were evacuated, but 243 people died from breathing in the fumes, China's worst gas-field disaster. on December 23, 2003, releasing hydrogen sulphide. There was an accidental sour-gas blow-out from a well in Kaixian County of southwest China at 10 p.m. The hydrogen sulphide content can present a real health hazard. Organic sulphur compounds present in crude oil have to be removed the sulphur they contain is converted to hydrogen sulphide, or to sulphur itself, which can be stored in blocks (shown below in blocks 25 feet tall on the prairie at Alberta, Canada). ![]() The H 2S can be removed by being converted to sulphur in the Claus process this is an important industrial source of sulphur. Some natural gas fields (such as Lacq in Aquitaine, France (shown right) Canada China the USA) yield gas which is often found to contain significant amounts of hydrogen sulphide, and is termed " sour gas". ![]() Most certainly not, eggs are only a very minor one. Is that the only source of hydrogen sulphide? Due to bacteria in the mouth, hydrogen sulphide may also be a cause of bad breath. The Curate: Oh no, My Lord, I assure you! Parts of it are excellent!ĭrawn by George du Maurier and published in the issue of Punchīacteria in the colon can form H 2S there, and it is released as a principal component of flatus. Right Reverend Host: I'm afraid you've got a bad egg, Mr. Originally the expression meant to call something bad, good, out of politeness or deference nowadays, the term is used to mean something partly good and partly bad. Yes, it is formed when proteins contained in the egg are decomposed by bacteria, making H 2S, as in the famous Punch cartoon (below), which gave rise to the expression "a curate's egg".
