Utley became just the second Washington State Cougar to earn consensus First-Team All-American honors. The Associated Press, United Press International, Scripps-Howard, Football News, the Football Writers of America, and the American Football Coaches Association named Utley to their First-Team All-America selections. He played his guts out on the offensive line and earned several accolades. It was a great way to conclude Utley’s final year with the Cougars. ![]() Utley also played in the Senior Bowl, East-West Shrine Game, and the Hula Bowl that season. The 18th-ranked Washington State Cougars beat the 14th-ranked Houston Cougars on Christmas Day, 24-22. The 1988 Aloha Bowl featured two ranked teams nicknamed “Cougars.” He went on to start a then-school record forty-three consecutive games. Utley was at the forefront of a high-octane Cougars total offense that led the Pac-10 and ranked third in the country. They also helped running backs Steve Broussard and Rich Swinton amass a combined 2,298 yards on the ground. Utley and his fellow offensive linemen helped Rosenbach rack up 3,097 passing yards and 24 touchdowns in the 1988 NCAA campaign. It was the Cougars’ first-ever win against a No. With Utley powering their offensive line, they beat the No. It was the Cougars’ best record in fifty-eight seasons. That would all change in the 1988 NCAA campaign – Utley’s last year with the Cougars. Washington State Athletics December 20, 2012 Happy birthday to Cougar great Mike Utley!

Merrill’s words would ring true when Mike Utley got involved in a life-altering freak accident on the gridiron when he suited up for the Detroit Lions that year. “I mean, he could ride a bike at 154 miles an hour and not get hurt, but then play a game of football and get hurt.” “I kind of look back at that with some weird feelings,” Merrill told The Washington Post in 1991. Merrill asked him if was scared and he replied in the affirmative. Utley told him the fastest he’d ever ridden was 154 miles per hour. One day, Merrill asked Utley what his top speed was on his motorcycle. ![]() Merrill told Freeman he hated Utley’s daredevil ways because he was worried he was going to get hurt. Utley turned on the afterburners and morphed into a speed demon whenever he rode his bike. He rode the motorcycle everywhere he went. When Utley was a senior, he purchased a Harley-Davidson motorcycle. Raising money to find a cure for paralysis. Hanging with former Detroit Lion – Mike Utley.

Some contemporary designs for larger, more elaborate pools include very large rock waterfalls that are a primary feature of the overall design. Waterfalls add the sight and sound of moving water to enhance environments, imbue tranquility and mask background noise. More Water in Motion: Waterfalls and Other Water Features MagicBowl is an example of a poolscape feature that’s ideally suited for new pool and remodeling installations. By night, the safe and energy-efficient LED lights combine with the flowing water to flicker and dance like an actual glowing fire, creating a truly enticing experience. By day, it can be appreciated as an architectural element. The MagicBowl™ Water Effects with FireFX™ LED Lights (sold separately) is the only water fountain bowl with elegant, lighted fire effects.

These energy-efficient lights mix and match individual LEDs to achieve a vibrant spectrum of color that can cycle at varying speeds and in different sequences. One example is Pentair’s IntelliBrite ® 5g Underwater Color-Changing LED Pool and Spa Lights. Today’s lighting systems also allow pool owners to define space and visual emphasis in the areas surrounding the pool to create intrigue and moods that extend deeper into the night. It has advanced from utilitarian, incandescent white pool lights to thrilling, multicolored LED lights that interface with user-friendly control systems, allowing pool owners to set the mood for any occasion. Pool lighting can do far more than increase visibility and safety for nighttime use. Lighting Sets the Mood in the Pool and in the Landscape Let’s take a look at some innovative lighting and water feature products that add the “WOW” factor to today’s pool environments. Pool designers and architects can help you integrate these features into a new pool or plan the most appropriate way to execute renovations. Others, like some lighting products, are simpler to add or retrofit to a pool environment. Some of these elements, like waterfalls and laminars, require additions or modifications to an existing pool’s plumbing and valves. The answer is a firm “yes.” Lighting and water features bring mood, movement and sound into the poolscape. Many design elements, and the way we perceive them, are simply visual and static. A pool’s location, size, shape, relationship to terrain, structures and landscaping are fixed and familiar. Are mood and movement essential elements of your poolscape?

The game's plot takes them through their efforts to rid Metro City of the new Skull Cross gang. The game features the return of the protagonist Guy along with Haggar and also introduces new characters Lucia and Dean. It is the second sequel to Final Fight released for the Super NES, following Final Fight 2, and like its predecessor, it was produced by Capcom's consumer division with no preceding arcade version released.

When Lucia was first released, many players believed she would end up top tier and potentially become one of the best characters in the game. This gives her literal fireballs that can be shot at strange angles and even bounce along the ground, a flaming spinning kick, and even a Dragon Punch-style set of up kicks that become engulfed in fire when her V-Trigger 1 is active.

She adds that the Point of the Mountain BRT under consideration is “what we call a gold-standard BRT,” which would allow level boarding from a platform (instead of climbing stairs), exclusive lanes for almost 90% of its route and off-board fare collection.īecause of some geologic challenges that trains would face at the steep Point of the Mountain but a BRT bus would not, Garver said a BRT system would also be able to offer an extra station at the prison site area - and is another reason for selecting it as the preferred alternative. Garver told the UTA board that when people are inside a BRT bus, “You wouldn’t know that you are not on rail because the vehicles are almost like” train cars in design. UTA is about to build a BRT line between downtown Ogden and Weber State University, and is studying other possible BRTs from northern Utah County to Orem/Provo (which could tie into a Point of the Mountain system), and from Davis County to downtown Salt Lake City. It also offers service every 6 minutes at peak times, often quicker than TRAX.

It also makes sense to use DSP on your artist's returns to influence their perfomance, pitch correction, compression and a slight reverb might make the artist feel they're sounding BIG and thus deliver more emotion on their takes. I do agree that baking it in is destructive and that it forces you to commit to what you've recorded to later on mix, but unless you're constantly second guessing yourself that's a nothing burger. Imagine you work with hardware for example, wouldn't it make sense to just slap on your 1176 on the way in if you were gonna use it with the same settings anyway? And maybe do some basic EQing to cut the lows on a vocal take since you'd do that later on too? Plus with hardware you spare yourself the time of having to re-record the unit's output later on when you do decide to run your signal through. When you really think about it, by recording wet you might be shaving off a full hour of work. The flipside of that coin is that recording wet you save time later down the line, so for a professional recording engineer who's accustomed to using the same compression settings for example it might make sense to just save themselves the time and bake that compression on the way in, same goes for wide tonal EQing and slight saturation. Instead of tracking both, and then adding tons of eq to the kick, and now your bass is fighting it.īecause I’ve been taught that you always want to record tracks as clean and dry as possible so you’re not limiting your mix later on by having to work with wavs that already have printed effects Seriously, how much time have you spent trying to get a bass and kick to work together that wouldn’t be necessary if your kick sound was solid when you tracked bass. Also, for me personally mixing became a lot easier when I started getting what I wanted when tracking. I can’t tell you how much time I’ve wasted over the years trying to make something unnecessary work. If I want the sound of an amp and di on bass, or multiple mics on a guitar amp, I’ll do it, but if a bass amp, or a single guitar mic is giving me what I want, I would rather commit to that than record a bunch of stuff to wade through later. ![]() For the same reason I don’t like to capture unnecessary tracks.

The nominal track separation on a CD is 1.6 micrometers, corresponding to about 625 tracks per millimeter. The tracks of a compact disc act as a diffraction grating, producing a separation of the colors of white light. The hydrogen gas in a thin glass tube is excited by an electrical discharge and the spectrum can be viewed through the grating. The illustration shows the hydrogen spectrum. ![]() It acts as a "super prism", separating the different colors of light much more than the dispersion effect in a prism. The diffraction grating is an immensely useful tool for the separation of the spectral lines associated with atomic transitions. However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating. The condition for maximum intensity is the same as that for a double slit. The relative widths of the interference and diffraction patterns depends upon the slit separation and the width of the individual slits, so the pattern will vary based upon those values. The overall grating intensity is given by the product of the intensity expressions for interference and diffraction. The intensities of these peaks are affected by the diffraction envelope which is determined by the width of the single slits making up the grating. There are multiple orders of the peaks associated with the interference of light through the multiple slits. This illustration is qualitative and intended mainly to show the clear separation of the wavelengths of light. Different wavelengths are diffracted at different angles, according to the grating relationship.Ī diffraction grating is the tool of choice for separating the colors in incident light. Orders 1 and 2 are shown to each side of the direct beam. ![]() When light of a single wavelength, like the 632.8nm red light from a helium-neon laser at left, strikes a diffraction grating it is diffracted to each side in multiple orders. The peak intensities are also much higher for the grating than for the double slit. The condition for maximum intensity is the same as that for the double slit or multiple slits, but with a large number of slits the intensity maximum is very sharp and narrow, providing the high resolution for spectroscopic applications. A large number of parallel, closely spaced slits constitutes a diffraction grating. This "super prism" aspect of the diffraction grating leads to application for measuring atomic spectra in both laboratory instruments and telescopes. The diffraction grating is often used in the laboratories for the determination of wavelength of light.When there is a need to separate light of different wavelengths with high resolution, then a diffraction grating is most often the tool of choice. 1.The grating spectrum of the given source of monochromatic light is obtained by using a spectrometer.Ģ.The arrangement is as shown in Figure shown below.ģ.The spectrometer is first adjusted for parallel rays.Ĥ.The grating is then placed on the prism table and adjusted for normal incidence.ĥ.In the same direction as that of the incident light, the direct image of the slit or the zero-order spectrum can be seen in the telescope.Ħ.On either side of this direct image a symmetrical diffraction pattern consisting of different orders can be seen.ħ.The angle of diffraction θ for a particular order m of the spectrum is measured.Ĩ.Thus using the equation (a + b) sin θ = mλ the unknown wavelength λ can be calculated by putting the values of the grating element (a + b), the order m and the angle of diffraction θ.ĩ. |
