Handling-wise, the 2023 Compass offers a driving experience much like any other compact crossover SUV: secure and stable, but not very communicative via (admittedly) decently-weighted steering or the seat of the driver's pants. The end result is a smooth and responsive powertrain that feels livelier and a lot more refined. There's no more need to chase the revs, either, because the boosted engine delivers a lot more torque than the old 2.4-liter, and does so at lower engine speeds as well. Gone is the old nine-speed automatic gearbox's hyperactivity, replaced by a much better-behaved eight-speed automatic. The driving experience in the 2023 Jeep Compass has been transformed by the arrival of the new turbo engine. But, with its attractive new face, nicer interior, and vastly-improved mechanical parts, the Compass has a better chance than ever of stealing at least some of their lunch money. This gives the 2023 Jeep Compass the performance boost it's needed all along.īuilt on the Stellantis (FCA) Small Wide LWB 4x4 platform, elements of which are shared with the smaller Renegade and larger Cherokee, the Jeep Compass has serious competitors in the Volkswagen Tiguan, Mazda CX-50, and Ford Bronco Sport. Power is sent into a new eight-speed automatic transmission before being distributed to all four wheels. The new unit is a 2.0-liter turbocharged four-cylinder producing 200 horsepower, up from the old 2.4-liter Tigershark's 177 hp, with 221 lb-ft of torque, up from 172 lb-ft. There was no change to the mechanical bits, but that oversight change came in for attention for the 2023 model year, thanks to a new turbocharged powertrain. To face these challengers, Jeep has given its second-generation Compass a comprehensive facelift for the 2022 model year. The compact crossover segment is one of the busiest in the USA, with enticing new options arriving on a regular basis.

These interactives are part of the student investigation: “ How can we learn about something we can’t see?“ĭan Damelin ( is a technology and curriculum developer. Only a concentrated charge could generate a strong enough field to do this, thus Rutherford concluded that atoms have a tiny, dense, positively charged nucleus. However, some particles were deflected and some bounced back from the foil. If the positive part of atoms was dispersed, he reasoned, the electric field generated by those atoms would not be strong enough to deflect the alpha particles. He shot alpha particles-very high-energy, high-speed, positively charged helium atoms-at a thin piece of gold foil. The “Rutherford” interactive (Figure 3) simulates Ernest Rutherford’s experiment to test this model. One possible model, commonly called the Plum Pudding model, postulated that the positive charge was dispersed throughout the atom with the negative electrons floating around in it. Otherwise, everything would be negatively charged and repel everything else. Once negative electrons were found, there had to be a positive component of the atom as well. The first subatomic particle to be discovered was called the electron. Combined with the fact that all metals seemed to produce the same particles, Thomson concluded that cathode ray particles must be part of all atoms. Cathode ray particles have much less mass than even hydrogen, the lowest mass atom. Now, compare the behavior of the negatively charged “cathode ray particles” with that of atoms in the “Electron Properties” interactive (Figure 2). Did you find that the particles always behave the same way when deflected by the charged plates, no matter which metal was used in the electrode? Adjust the charge on the plates and select different metal electrodes.

They reveal the emergent behavior of atoms and molecules and give students the opportunity to use data from observations to reason about atoms and their underlying structure. Our Next-Generation Molecular Workbench interactives are designed to help. To understand why, students first need to understand the composition of atoms.Ītomic theory is one of the most challenging topics to address in the constructivist classroom. At the atomic level, the primary interaction is based on electrostatic fields and forces. Many phenomena across multiple fields can be explained using this framework. The curriculum is based on the idea that much of what we see around us is the result of interactions between atoms and molecules. This ninth grade course, developed in partnership with the CREATE for STEM Institute at Michigan State University and the University of Michigan, is inspired by the Framework for K-12 Science Education and the NGSS, which encourage students to learn science by engaging in science practices. The Interactions project is developing a new interdisciplinary semester-long course that lays the foundation for deeper understanding in physics, chemistry and biology.
In the United States, where "I Wanna Have Some Fun" had been a Top Ten hit, "I Only Wanna Be with You" rose no higher than number 31 and would mark Fox's final Billboard Hot 100 appearance: in Fox's native UK her version outperformed her previous six single releases with a number-16 peak, but would also become Fox' final major hit bar her 1998 one-off comeback single " Santa Maria". "I Only Wanna Be with You" essentially earned Fox her final global hit single. Fox also promoted the song via televised performances, including those on Top of the Pops in 1989 and Viva el espectáculo on TVE1 in 1990. Released as the follow-up single to the album's title cut, "I Only Wanna Be With You" was promoted with a music video which included scenes of Fox hunting through trash cans, dancing, fireworks, and the singer in bed with her bespectacled lover. In 1988, English singer Samantha Fox covered the song as "I Only Wanna Be with You" for her third studio album, I Wanna Have Some Fun (1988).įox would recall the song as being the first song she ever learned to sing, the Dusty Springfield original version being among a stack of singles her mother handed down to Fox when Fox was aged ten. Ivor Raymonde is best remembered as the co-author and arranger of many of Dusty Springfields biggest hits, including 'I Only Want to Be with You,' and as music director on her classic Philips Records albums. I dont know what it is that makes me love you so I only know I never want to let you go Cause you started something, cant you see That ever since we met youve had a hold on me I happens to be true, I only want to be with you It doesnt matter where you go or what you do I want. Three remakes of the song have been UK chart hits, the first two by the Bay City Rollers (1976) and the Tourists (1979) matching the number 4 peak of the Dusty Springfield original, while the 1989 remake by Samantha Fox peaked at number 16. Watch: New Singing Lesson Videos Can Make Anyone A Great Singer. The debut solo single released by British singer Dusty Springfield under her long-time producer Johnny Franz, "I Only Want to Be with You" peaked at number 4 on the UK Singles chart in January 1964. The original version appears on the 2001 Dusty Springfield anthology, Ultimate Collection."I Only Want to Be with You" is a song written by Mike Hawker and Ivor Raymonde. In the 1980s, Nicolette Larson managed #15 on the Adult Contemporary chart and #53 on the pop chart, Luis Miguel topped the Billboard Hot Latin Tracks chart, and Samantha Fox hit the trifecta by charting in America, Australia, and the United Kingdom. The song has continued to be a gold mine for any artist with the talent to handle it. The Tourists enjoyed similar success with their 1979 cover: Although it only grazed the Billboard chart at #83, it scored the same chart positions as Dusty’s original in the Australian and British markets. The Bay City Rollers took it back into the charts in the 1970s, with eerily identical chart numbers, reaching #4 in Great Britain, #8 Down Under, and #12 in the States. I Only Want To Be With You (Performing At The Ed Sullivan Show) Music Video. It peaked at #4 in the U.K., #6 in Australia, #12 in the U.S., and #21 in Canada, and has the distinction of having been performed on the first episode of Top of the Pops, on 1 st January, 1964. Song written by Mike Hawker and Ivor Raymonde that was the first single and hit recorded by Dusty Springfield as a solo artist. Mind that all screws are very small with the exception of the 3 long ones (as indicated below): Opening your MacBook Pro is EASY … flip your MacBook Pro upside down and remove the screws as show below (from Apple’s website). People claiming that Apple charges a “ premium” price probably never owned an Apple computer, and should realize it is because you buy real quality hardware, superior to any of its plastic counter parts in Windows world. I have taking plenty laptops and dekstops apart and Apple’s laptops (specifically the unibody models) and desktops (love the Mac Pro!) win by a mile from regular PC hardware. I absolutely LOVE Apple hardware, not just for the look, more so for the art of how they build their hardware. One harddrive adapter for an optical bay (I used this one from Amazon) as displayed earlier.An old towel to work on and prevent scratches ….Well, let’s see, this process took me about 5 minutes and I only used Read this article for more details on how to get RAID-0 going in a setup like this – be aware though that although wicked fast, if one disk fails: all your data will be gone … ( RAID-0 writes data split to both disks – which makes it so fast). Note that when you’re using two identical (size) drives then you could consider a RAID-0 setup which will be wicked fast, specially when using SSD drives. I really like speed, so I went with another 160Gb Intel SSD (probably not for everybody’s budget), but if you’re planning to just use it for massive storage then a regular 2.5″ harddrive as well offering more storage capacity at a much lower price. The choice of drive is completely up to you. This link will help you identify the MacBook Pro model you have … For older models you’ll have to do some homework to figure out if the optical drive is actually using SATA. Newer models, and I believe any of the unibody models, will be equally easy to convert. If you have a MacBook pro like I do (15″ mid 2010 MacBook Pro a.k.a. MacBookPro6,2) then this guide will work without even having to think. You will have to pay attention here – some of the older MacBook Pro’s appear to have a PATA (classic IDE/ATA) connector and those will not work with a SATA disk. These electrons move from their ground states to higher energy states. The frequencies of this emitted light comprise their emission spectrum.Ībsorption spectra, in contrast, concern light frequencies of electrons that absorb energy. These excited electrons must then release, or emit, this energy to return to their ground states. Emission spectra involve electrons moving from lower to higher energy levels, which occurs when they take in energy. Two main types of spectra exist, emission spectra and absorption spectra. Distinguishing Between Emission and Absorption Spectra This final step produces physical emission and absorption spectra. This information feeds into a computer, allowing the software to calibrate and plot it as a function of wavelength and spectral range. Within the detector, photons are converted into digitized electrons. Concave mirrors ensure that these frequencies then reflect onto a detector. This light gets directed onto a grating, dispersing it into its different frequencies, which correspond to energy levels. Light first passes through fiber optic cables and into the spectrophotometer through the entrance slit. Spectrophotometers are responsible for producing both emission and absorption spectra. Different photons reflect different wavelengths and energies, and thus produce different colors, which appear on these produced spectra. The spectrophotometer measures the amount of photons that fall into these categories, converting the information into a digital display, or spectrum. The sample may either transmit or absorb each different wavelength of this incoming light transmitted light passes through the sample, while absorbed light gets taken in by the sample. They place this sample into the spectrophotometer, which then floods it with a continuous stream of light particles. Say, for example, scientists want to determine the components of a reaction product. Let’s go over this process and its implications in more detail. When this light contacts the substance, it separates into its various wavelengths Scientists place cuvettes of different materials into the machine, which passes light through the samples. The spectrophotometer essentially functions as a glorified prism. When visible light passes through a prism, its component wavelengths split due to their varying energies and travelling speeds. Exploring the SpectrophotometerĬolors and associated energies are therefore two key components of spectrophotometric investigations. For example, as measured in nanometers (nm), blue and purple light exhibit shorter wavelengths, while red light displays longer wavelengths. Shorter wavelengths denote higher energy levels, while longer wavelengths correspond to lower energy levels. The color of traveling light corresponds to the lengths of its photon-comprised waves, which relate to the energies of these photons. This flow of photons resembles the shape of a wave because this electromagnetic wave is composed of discrete parts, or photons, it is not continuous. These photons move so fast that, in a single second, each covers 180,000 miles. Sources of light emit particles called photons. Below, we cover the mechanisms and applications of spectrophotometry in more detail. This process provides insight into protein synthesis, DNA and RNA function, bacterial cell growth, enzymatic reactions, and more. Spectrophotometry involves the measurement of a substance’s concentration, amount, and identity. It facilitates developments in energy, pharmaceutical, health care, agricultural, manufacturing, and forensic realms. Spectrophotometry informs research in the physical sciences, including chemistry, biology, physics, geology, and astronomy.

The Utah Department of Transportation had applied for a $500,000 grant to study how best to connect Salt Lake City to Las Vegas by passenger rail, but the application was denied. (Rick Egan | The Salt Lake Tribune) Amtrak riders board a train in Grand Junction, Colo., in 2007. Gleason added after the announcement Friday that UDOT is “always looking for transportation solutions to address growth and help people get where they’re going safely and conveniently.” UTA on Friday concurred with UDOT’s statement, a spokesperson said. “I like the concept of putting this region, this service area, right in the middle of the discussion for a larger intercity presence,” Utah Transit Authority executive director Jay Fox said at the time, “which will ultimately give people more opportunities to take modes of transportation that are not available to them right now.” The Utah Transit Authority last month hosted a hopeful luncheon to reveal plans for the proposed Salt Lake City to Las Vegas and Boise passenger rail projects. “Policymakers missed the mark by not advocating for a more efficient use of land for our transportation needs - content to simply spend our money to add lane after lane of highway and road,” Haring wrote in an email. He also cited a lack of enthusiasm from policymakers - in Utah and the surrounding region - as a potential reason. “Officials have stressed the importance of local support playing an important role in their decision-making process,” Christensen wrote in an email, adding that Utah will need “a bottom-up, grassroots effort to build a coalition of communities in order to win over Utah’s congressional delegation, the Utah Legislature, and UDOT.”Ĭurtis Haring, executive director of the Utah Transit Riders Union, said the organization felt the funding rejection was disappointing but not surprising. But he feels Utah needs to “change its approach” if it expects to see federal support in the future. There will be an opportunity for UDOT to apply for grant funding again next year, Utah Rail Passengers Association executive director Mike Christensen said. And in Colorado, $500,000 in federal grant funding was awarded this week to a passenger rail project between Fort Collins and Pueblo, the Denver Post reported. In Nevada, plans for a potential Las Vegas-to-Los Angeles high-speed rail system received $3 billion in federal support this week, the Las Vegas Review-Journal reported. Federal officials ultimately chose 69 projects to receive grant funding, according to a news release from the Federal Railroad Administration. The application was denied, the Federal Railroad Administration announced Friday.Īcross the country, about 90 such grant applications were submitted. (Utah Department of Transportation) UDOT applied for a $500,000 grant that would fund an exploratory look at rail service between Salt Lake City and Las Vegas. It was the fifth girl at the table, a hot pink symbol of modern women. The women were often seen with the pink paragon-whether at lunchtime, on a date with Big in a clingy matching pink dress, or passing the Bechdel test together over drinks. Global recognition came later in the ‘90s with Sex and the City, a show centered on female friendship between the canonical Carrie, Miranda, Charlotte, and Samantha. ‘Boyfriend! Two more of those pink drinks!’” Says Cecchini, “They were older than me and called me boyfriend. Soon, Madonna was drinking them like a fish with actress Sandra Bernhard. She told this to bartender Cecchini, who made his own version, shaking up the drink we know today- an icy pink froth of vodka, cranberry juice, fresh lime, and Cointreau, served in a thin-stemmed Martini glass or low coupe. As the story goes, an Odeon waitress had just been to San Francisco, where an early Cosmo-then just vodka, Rose’s sweetened lime juice, and syrupy grenadine-was making the rounds. But most agree the cocktail canon is this: bartender Tony Cecchini created the cocktail at New York restaurant hotspot the Odeon in 1988. Others think Cheryl Cook, the Martini Queen of South Beach, invented the pink drink-the lovechild of a Kamikaze and cranberry juice. Lore says the first Cosmopolitan may have been served in the Rainbow Room in the late ‘80s vis-à-vis bartender Dale DeGroff. Then, they go for the jugular: What, are you from the Midwest? Cheesy! Overdone! The public vitriol cuts-our overlords are out for blood. Have you ever had a Cosmopolitan? Likely not recently-since the Cosmo, though a classic, has, over time, become a has-been-shunned by the masses, thrown over for younger, sexier cocktails.

state of Kentucky in 1831, which included a right mandible and a clavicle. The history begins with the first discoveries of Richard Harlan (1796-1843) at Big Bone Lick in Boone County in the U.S. The research history of Paramylodon is complex and characterized by more than 150 years of confusion with Mylodon and Glossotherium. History of research Discoveries in North and South America The first fossil finds of Paramylodon published by Richard Harlan in 1831 Richard Harlan 2019, showing the position of Paramylodon. īelow is a phylogenetic tree of the Mylodontidae, based on the work of Boscaini et al. McAfee also suggest that Paramylodon and Glossotherium are very closely related and share a close common ancestor. Detailed morphological analyses published as early as 2009 by Robert K. This view also finds support from the aforementioned biochemical data, also presented in 2019. According to the study, Paramylodon, Glossotherium, and Mylodon form a closer relationship within the Mylodontinae. In the same year, a more-detailed phylogenetic analysis of the mylodonts was published by a research group led by Alberto Boscaini. In this study Paramylodon and Glossotherium were found to be closely related, Mylodon, on the other hand, forms the basis of the advanced mylodonts and Lestodon clades with some forms from northern South America. In contrast, a study presented in 2019 by Luciano Varela and other involved scientists, which includes numerous fossil forms of the entire sloth suborder, partially challenged this. Paramylodon is usually considered closely related to both Mylodon and Glossotherium. Mylodontidae is grouped together with modern two-toed sloths of the family Choloepodidae and the extinct Scelidotheriidae, in the superfamily Mylodontoidea, with the former family being their closest living relatives. Paramylodon is an extinct genus of sloth from the extinct family Mylodontidae. The morphology of the forelimbs has led to suggestions that Paramylodon may have engaged in burrowing. Paramylodon lived in open landscapes, sometimes also in mountainous locations, and were grazers or mixed feeders. Like some other mylodontids, Paramylodon had osteoderms embedded within its skin. Only since the 1990s have both genera been considered distinct, with Glossotherium restricted to South America, while Paramylodon inhabited North America. Paramylodon shares numerous features that suggest a close relationship with Glossotherium. Over 150 years after the description of the first species, the finds that are now attributed to Paramylodon were repeatedly placed in with other genera, first with Mylodon, but since the 1950s increasingly with Glossotherium. The genus Paramylodon was introduced by Barnum Brown in the early 20th century. They go back to Richard Harlan, in whose honor the species was named. The first fossil findings date back to the beginning of the 1830s. Within the genus only two species are recognized: Paramylodon harlani, also known as Harlan's ground sloth and Paramylodon garbanii, though the placement of the latter in the genus has been questioned by some authors. Paramylodon is an extinct genus of ground sloth of the family Mylodontidae endemic to North America during the Pliocene through Pleistocene epochs, living from around ~4.9 Mya–12,000 years ago. |
