3/16/2024 0 Comments Tick identification deer ticksThis tick is most easily identified by its reddish-orange body, black shield and dark black legs. The following is a list of ticks found in the United States that are known to bite and transmit disease to humans: In some areas the nymphal tick infection rate is actually higher than the adult tick infection rate. While both hard and soft adult ticks are easiest to identify, it is important to note that nymphal ticks are equally capable of transmitting disease. The bite is typically painless and only lasts 15-30 minutes, making it harder to detect. Soft ticks’ life cycle lasts from months to years depending on the species. Nymphal soft ticks may go through as many as seven phases as nymphs, requiring a blood meal at each stage. Soft ticks (Argasidae), like hard ticks begin as an egg, hatch into a larva, feed and then molt into a nymph. The bite of a hard tick is generally painless, with a feeding process lasting several hours, to days, even weeks. The life cycle of hard ticks lasts one to two years depending on the species. Nymphal hard ticks then seek larger hosts, and after feeding drop off and molt into adults. After feeding it drops to the ground from the host and goes through a molting process, emerging as a nymph. Once the egg hatches a larva emerges that must then find and feed on a small mammal or bird (host). Hard ticks (Ixodidae) begin as an egg that is laid by an adult female tick. Hard ticks and soft ticks have different life cycles, growing larger and changing their appearance at each stage. Of the 700 species of hard ticks and 200 species of soft ticks found throughout the world, only a few are known to bite and transmit disease to humans. There are two families of ticks found in the United States: Ixodidae (hard ticks) and Argasidae (soft ticks). With its origins dating back until the mid-1800s, people have been playing Spite and Malice for a very long time. Hopefully, you can use some of these tips on how to win at Spite and Malice in your next game. Fill all discard piles before putting cards on top of each other, but reserve some piles for high cards only so you avoid burying low rank cards. If you cannot play a matching card, play low cards on top of high cards instead of high cards on low cards. Ideally you make piles with cards of the same rank because this prevents burying any card. Play cards to the discard piles wisely: Prefer playing high cards to the discard piles over low cards.Use Kings wisely: Kings are wild in Spite and Malice and hence are very helpful to reach your goal card, but remember they can also be used to prevent your opponent from playing his goal card.Clear your hand: Playing all five cards in your hand so you get five new cards is a good move, as long as it doesn't help your opponent.For example, if you have a 10 as goal card, keep cards like 7-8-9 in your hand. Use your hand to reach your goal card: Cards in your hand are always playable, so the most helpful hand cards are the cards right before your goal card.Keep an eye on the opponent's goal pile: Avoid playing cards that might help your opponent play the top card of his goal pile, except if it serves you as well. Avoid playing cards just because you can play them. Focus on your goal pile: Always focus on playing the top card of your goal pile.The turn finishes when a card is played from the hand to one of the discard piles.Kings are wild and can be played on the playing piles to substitute any other value.Cards that can be moved to the playing piles are the top card of the goal pile, the top cards of the four discard piles, and any card in your hand.Suits of the cards don’t matter in Spite and Malice. Playing piles must start with an Ace and are built in ascending order up to a Queen (A-2-3-4-5-6-7-8-9-10-J-Q).Then, the player plays cards from his goal pile, hand or discard piles to the playing piles.At the start of each turn, cards from the common draw pile are dealt until the player has five cards in his hand.The rest of the cards go into the common draw pile, face-down. The top card of the goal piles is turned face-up. There are four common playing piles and a common draw pile.Īt the start, a certain amount of cards are dealt to each player's goal pile, face-down. Spite and Malice is played with three decks of 52 cards each, hence 156 cards in total.Įach player has their own goal pile, four discard piles and a hand with maximum five cards. In most computer versions, such as the one we feature here, the game is played with two players. Spite and Malice can be played with two to four players. The first player to empty their goal pile wins. The object of Spite and Malice is to get rid of all your cards in your goal pile by placing them on the playing piles. How to play Spite and Malice Table of contents It's easy to do money on engines.the question is.How fast do you want to go? You will have to factor in some machining costs in that you may need re-bores and crank polishing or grinding, plus new shells, pistons, rings and cam bearings, which isn't cheap any where. fit new timing set, most go for the Cloyes double roller/ sprocket type and you'll need to get the engine balanced and fit a new Harmonic balancer.That will get you well over 400 horsepower! May work better with a spread of sparks during the firing cycle but I never bothered. Use them, and heavy duty pushrods that match the cam and will work with a higher ratio rocker.įor ignition I found that the Mallory dual point with out vacuum advance works absolutely fine without the need for MSD. I'm not sure if the 62 heads had threaded rocker studs or not offhand, but I know the Edelbrock heads DO. A set of new lifters will definitely benefit the valve train but keep to the hydraulic type if you dont want to make some changes in the valve train area. It'll work fine with your stock transmission and rear gears.That cam found its way into the tri-power 421's and a lot of other HO engines. Start with a lighter head and intake section.Įdelbrock performer, or performer RPM intakes on top of a pair of Edelbrock performer RPM heads, a set of forged or Hyper-eutectic pistons(quieter and with better heat expansion properties IMO) a studded bottom end, a set of Eagle rods, a set of 1.75 higher ratio roller rockers and a 250 to 280 degree cam which is near enough to the number 68 grind cam I favour. What's your budget and do you intend to lighten the car? So.the jump has been made to square bore carb and manifold.you have 62 Heads, with big valves i.e., 2.11 intake and 1.77 exhaust valves.has any porting and or port matching and/or flow testing been done? It isn't possible to overcarb your engine since the Rochester will only flow the required amount you need at any time.Pontiac did make aluminium HO intakes.part number 483674 is a good one to get but will be rare and expensive to buy. The stock Rochester will supply all your fuel you will want up to 750 cfm reliably.VERY reliably, based on the Pontiac stock intakes produced at the time. So, for my money, a manifold somewhere between the two, that is to say, a good torque generator and one that will respond in the lower rev ranges, and one that will make use of better heads, cam and carb. That's a given.The Edelbrock Torker Manifold was in the high performance manifold category, intended for lighter weight cars which accelerated quickly through the lower rpm ranges, and had the internals to rev to higher rpm levels around the 6,000 mark, and flowed better through the higher rev ranges. Now if you have a car that weighs in at around the 3,500 lb mark then you need low rpm torque to get you off the line efficiently. You will find that the stock performance manifolds work best on engines with8- 9.5:1 compression ratios and usually rev to around the 5,000-5,500 range, i.e., Pontiac. I would adventually like to have 400-475 horsepower. Any pointers or suggestions would be greatly appreciated. Is this a good decision or to much carb and will this carb work well with the edelbrock performer rpm manifold? I was thinking of putting in a Holley 770 cfm street avenger also. Also, I assume the carb is a little undersized as I know Pontiac put 750 q jets in as a stock carburetor. Should one or both of these be changed? I have heard a lot of people say the orginal torkers didn't work well, and to go with an edelbrock performer rpm. It has an edelbrock torker manifold and a Holley street avenger 670 carburetor on it now. I am still trying to figure out the engine vin number very tough to read in the rear of the passenger side. I know it is not a numbers matching engine as it has wt stamped for an engine code and it has 62 heads so I'm pretty sure its a 68 to 70 engine if I where to guess. At higher rpms everything seems fine, it will even squeal the tires between first and second. I just put a 3:73 rear end and it has the original automatic 3 speed transmission in it. The take off seems a bit sluggish and has a hard time spinning the tires even. The question I have is it seems to run ok, but not like I remember of a 1968 I once rode in.

From the 113th Congress to the 117th Congress, 67 special elections were held. Īs of February 19, 2024, nine special elections have been called for the 118th Congress. House voted to expel Santos on December 1, 2023. This was the first election after the 2020 round of redistricting, which analysts assessed shifted the district towards Republicans. In the 2022 election, Santos defeated Robert Zimmerman (D) 53.7%-46.2%. Candidates for the special election were still eligible to run in the regular 2024 election. Suozzi will serve the remainder of Santos' term, which ends on January 3, 2025. A win for Pilip would have expanded the Republican majority to an eight-seat margin of 220-212. Suozzi's win expanded the Democratic minority, bringing the partisan balance to a six-seat margin of 219-213. At the time of the election, Republicans had 219 seats to Democrats' 212, a seven-seat margin for Republicans.

Hofstra University professor Lawrence Levy said the issue could affect turnout for Suozzi: "There’s not an inch of daylight between Suozzi and Pilip on support for Israel.but the Democratic Party is seeing younger voters at odds with Israel." In an interview with Politico, Suozzi said Democrats who opposed U.S. Local political analysts said that support for Israel was likely to be an issue in the race, with both Suozzi and Pilip saying they were strong supporters of the country. Because this was a special election, leaders in the Queens and Nassau county parties selected both candidates rather than holding primaries. Suozzi represented an earlier version of the district from 2017 to 2023 and was a candidate for governor in the 2022 Democratic primary, while Pilip had served in the Nassau County Legislature since 2021. The election was called following the expulsion of George Santos (R). Tom Suozzi (D) defeated Mazi Pilip (R) in a special election in New York's 3rd Congressional District on February 13, 2024.

It marked the last time Alan was to see Lehman, who he considers his most vital and important teacher. Lehman Engel came down to critique and help, as part of his relationship with that program. Based on ‘A Midsummer Night’s Dream’, it was developed and performed as part of the theater curriculum at Southern Methodist University in Dallas, just after the ‘Little Shop’ opening. It was written to go straight into the stock and amateur market. Another musical Alan wrote, also in 1982, was ‘The Dream On Royal Street’. Most exciting was a movie deal, which opened doors to Hollywood. Productions followed in Los Angeles and London, along with national tours and all the rest. Marks Place, where it ran for over 5 years and set the box-office record for highest grossing Off-Broadway show of all time. It moved to the Orpheum Theater on 2nd Ave and St. Based on the Roger Corman B-movie classic, it opened at the WPA Theater in the spring of ’82, to great reviews, lines around the block and countless offers from producers. Littleshop Then came ‘Little Shop of Horrors’, the musical that put Ashman and Menken on the map as in-demand, up-and-coming musical theater writers. But starting in 1978, when they met to discuss a musical of Kurt Vonnegut’s novel, GOD BLESS YOU MR ROSEWATER, Alan and Howard became a songwriting team and with only a few exceptions, Alan has seldom returned to lyric writing. Until working with Ashman, Alan Menken was almost exclusively a composer/lyricist. He contributed material to revues like ‘New York’s Back In Town’, ‘Big Apple Country’ and ‘The Present Tense’. He showcased material from early musicals like ‘Midnight’, ‘Harry The Rat’ and ‘Apartment House’. He performed his material at clubs like The Ballroom, Reno Sweeny and Tramps. In the years between graduation and actually earning a living as a composer, Alan worked as a ballet and modern dance accompanist, a musical director for club acts, a jingle writer, arranger, a songwriter for ’Sesame Street’ and a vocal coach. As of November 26th, 2019, they are together 48 years and married for 47. The work itself has mercifully faded into the distant past, but one aspect of that experience became the best moment in his life meeting a beautiful ballet dancer named Janis Roswick. Alan found his first and best network for learning and growing into the composer he now has become.Įarly career Upon graduating from NYU, he took a collection of his songs and wrote a rock-ballet for The Downtown Ballet Company, called ‘Children Of The World’. Even though his plan was to become a rock-star-recording-artist, he would dabble in writing more musicals through that workshop. Most importantly, he escaped to the piano practice room every chance he got and wrote songs and a Musical for the Hall of Fame Players ‘Separate Ways’ (featuring that musical theater classic – “Thank God for Marijuana”.) Most importantly, to appease his parents, he auditioned for (and was admitted into) the BMI Musical Theater Workshop, taught by eminent conductor and composer, Lehman Engel. What could he do? That stress became a peptic ulcer in Junior High School, which Alan didn’t fully cure until those magical, psychedelic, wonderful hippie years of 1967 thru 1971, which just happened to coincide with the period he attended New York University’s College of Arts and Sciences, where Alan drifted from Pre-Med to Anthropology major to Philosophy major to finally graduating with a degree in Musicology. When his piano teacher, Emily Harris, or his violin teacher, Editha Braham realized what he was doing they wisely suggested that this be encouraged, so Alan began composing, as well as pretending to practice.Ĭollege years Too bad he’d never be able to make a living doing that. Instead of learning pieces, Alan would get the basic idea of a Beethoven Sonata or a Bartok Mikrokosmos and spend the rest of his practice time “faking it”. Studying was like pulling teeth (no pun intended) and even practicing piano was a trial. Much as he would have expected to become a dentist, like most of the other men in three generations of his family, he was a very ADHD child. Alan’s ambition, from his earliest memories, was to become a composer. He grew up in a home, filled with music and theater (and comedy and drama) in New Rochelle, New York, along with his sisters, Faye and Leah. Early years Alan Menken was born July 22nd, 1949 at French Hospital in New York City, to young aspiring actress/playwright, Judy Menken and boogie-woogie piano-playing dentist, Norman Menken, DDS. 3/15/2024 0 Comments My ip location google mapsIn my opinion, that's why the reporting earlier this year about Apple's pivot towards advertising is such a big deal. If they can't tie data they're collecting to more revenue, there's not as much incentive for them to collect that data. And "advertisers" isn't a well-defined demographic.Īpple's cost-benefit analysis when it comes to collecting user data is much ore clear-cut. The existence of that third party in Google's motive (i.e., advertisers) incentivizes Google to collect data more aggressively, because as long as the people using Google are "happy enough" to not leave the platform, Google stands to benefit from collecting more data for advertisers. When Apple collects data on you, it's mainly so that Apple can interact with you, and get you to pay Apple so that Apple makes money. When Google collects data on you, it's mainly so they can let other companies interact with you (ads), and those companies pay Google so that Google makes money. I think the important distinction is in the business reasons that Apple and Google collect data. I assume our locations are being provided based on the MAC of the nearest router(s), but it's not clear why those router MACs get associated with such far-flung and uncorrelated places.Īpple does this, but to a lesser extent. Currently we are showing up as being in the middle of a lake outside a town of 30000 people, though the FCC believes that area is only served by satellite internet providers. The location will change maybe every few months. Whether or not we're connected (or have ever been connected) to the company network, people in my office will find that our detected location is maybe 200 mi away from our office, often in places that have none of the same ISPs as our headquarters and are nowhere near any of our facilities. Few employees have company-issued phones connected to the network. I work at a satellite office about a mile from the main headquarters, but we have facilities (mostly small storefronts) over about a 1000mi radius from that location. My workplace has extremely bad cell coverage and no GPS coverage indoors. On laptops and desktops with no GPS, browsers will use this access point data to set a location - IP addresses databases are not up to date enough and sometimes they are linked to the ISP office address and not to specific towns and cities and certainly not to a specific address. While a fix is not available phone GPS uses any visible MAC address to determine its coarse location. A GPS get a fix faster if you are using it close to where it was last used, or how fresh the stored almanac data is, otherwise it may not find expected satellites in certain locations in the sky. Actual GPS takes a few moments to get a fix, even more if indoors. This information is also used for a GPS cold start. If you live in a location with low traffic/human density then it may take longer for Google to change it back. It may not link that data to your account, but it uses it to help getting a GPS location. In your case, if you used your phone via the VPN for more than a few hours, Google associates that MAC address with the finer location from your phone's GPS. Google logs your current location and the MAC address of any access point visible to your phone. It took a couple of weeks for Google services to catch up. For a few weeks his computer and other devices reported his location as being my city instead of his. Many years ago, I gave a friend in another city a router. Not you IP address but your router/access point's MAC address and been doing it for many years.įor example, I receive quite a few devices for reviews, and I mostly give things away after using those. 3/15/2024 0 Comments Collar ties for roof raftersJack rafters are shorter, inclined members that connect the common rafters to the hip or valley rafters. They join the ridge to the eaves and help support the weight of the roof in these critical areas. Valley rafters are inclined members that run along the internal angles formed by the intersection of two roof surfaces. Hip rafters are commonly used in hipped roofs and are essential for distributing the load from the roof to the walls. They provide support and stability to the roof's hips (external angles formed by the intersection of two roof surfaces). Hip rafters are diagonal members that connect the corners of a roof to the ridge. Common rafters form the basic framework upon which other types of rafters are installed. They extend from the ridge to the wall plate and are typically evenly spaced along the roof's length. Common RaftersĬommon rafters are the main load-bearing members in a roof system. A few examples of the types of rafters used in construction are listed below.įigure 2: Common rafter types of a house roof framing. The specific design and configuration of rafters will depend on factors such as roof’s shape, slope and the structural requirements of the building. By distributing the load evenly, rafters ensure that the structure remains stable and can withstand various external forces, such as wind and snow loads. The primary function of rafters is to transfer the weight of the roof to the walls or other load-bearing elements of the structure. They are inclined beams that extend from the ridge of the roof to the eaves and support the roof covering material, such as shingles or tiles.įigure 1: An example of exposed timber rafters landing on a lintel. Rafters are structural elements that form the framework of a roof. But have you ever wondered how it stays up there without crashing down like a house of cards? Picture this: you're standing beneath a roof, admiring its structure. So, grab your hard hats, dust off your drafting pencils, and let’s raise the roof, both literally and figuratively. We will also discuss different materials used for rafters, such as wood, steel, and cold-formed steel, along with practical tips for rafter design and analysis. In this article, we will explore the definition, function, and various types of roof rafters, including their unique features and applications. They are essential components that provide strength and support to the roof system. Rafters play a crucial role in supporting the roof, distributing its weight evenly, and ensuring the overall stability and integrity of the structure. In any structural design project, the importance of roof rafters cannot be overstated. Even though roof trusses are more commonly used than rafters, they do not provide the same versatility and space for creativity that rafters allow. Choosing the right “hat” for your building will depend on several factors, such as wall layout, ceiling type, and architectural features.

I agree with Jayrod12, I can imagine 50-60% of the total weight of the machine on one wheel under the worst conditions. RE: Scissor Lift on Grating human909 (Structural) 7 Nov 19 21:01 If you are unable to make sure that the unit won't be used while it sits on the grating, make sure you factor in the recomended lateral loads for construction work platforms in ASCE 37 (I don't have it in front of me but I believe it's 50#/worker or 2% of total load, whichever is greater). Unless you're going to lay plate over the entire walking surface (slip hazard, and heavy - the structure may not be able to handle it) or have a group of people picking up and moving steel plates from behind to in front as it moves, it doesn't sound like a practical way to solve the problem. The difficulty here is that you're looking at a moving load. The spring constants of the supports will be based on the flexural stiffness of the bars at that point. Essentially, you'd have a point load in the center of the plate (+/- some reasonable distance) supported on several springs. To analyze a plate to spread the load, you'd have to look at the relative stiffness of the bars and the plate. RE: Scissor Lift on Grating human909 (Structural) 7 Nov 19 19:50 That wheel load is all on those 6 or 8 grating bars. or channel will bring more grating bars into play. or channels and the grating, you want to match the deflections of the two systems, which then determines the load distribution to X number of grating bars. As a function of the relative stiffnesses of the pls. or the channels atop the grating, become a gridwork of beams in terms of carrying and distributing the wheel loads. It seems to me that there might be plenty of times when you could have two wheels on the same effective width of grating, so look at that too.Įdit: The pls. That quickly leads to instability on that narrow a machine. I agree with the above, that wheel deflection and basket translation at full extension, may be just as important as actual grating carrying cap’y. This would add some weight and fiddling during machine movement, needing 4 pieces in total, but it would also distribute the load to an extra 8 or 10 bars in the grating, increasing the effective beam width. Maybe 8” wide channels, 6-8’ long, with upturned flanges, would be even better than pl. Why not add a couple steel plates under the wheels, maybe 1’圆’x.5” thk. I'm mechanical, not structural so I'm not sure if this math checks out, it makes intuitive sense to me, but any advice would be greatly appreciated. I used example 2 with the only changing being K ( I used 3.78947 whereas they used 10.1), there are only that many bars supporting load for the tire width given above 4.5".Ĭ = 4Mw/L = 252.42 lbs (much less than 687lbs)įor my load I just divided 687/252.42 because load/displacement linear relationship, and then multiplied Dc by this value to get I utilized the Metal Bar Grating Engineering Design Manual found here.

The grating is McNICHOLS (3/16 by 1 1/2 with a c-c distance of 1.1875"). The scissor lift is a Genie 1930 model, and weights 2748lbs, I'm assuming a concentrated load of 687 (one tire, which is not conservative, because tipping could occur, but even so it fails). New Member here, and I have seen a few of the other post about scissor lift on gratings but am still unclear on how to go about determining the load capacity of grating given a contact patch of about 4.5" (tire width) by 4" (tire length). |
