The Fire and Fire Surrogate (FFS) project is a large long-term metastudy established to assess the effectiveness and ecological impacts of burning and fire "surrogates" such as cuttings and mechanical fuel treatments that are used instead of fire, or in combination with fire, to restore dry forests. One of the 13 national FFS sites is the Northeastern Cascades site at Mission Creek on the Okanogan- Wenatchee National Forest. The study area includes 12 forested stands that encompass a representative range of dry forest conditions in the northeastern Cascade Range. We describe site histories and environmental settings, experimental design, field methods, and quantify the pretreatment composition and structure of vegetation, fuels, soils and soil biota, entomology and pathology, birds, and small mammals that occurred during the 2000 and 2001 field seasons. We also describe the implementation of thinning treatments completed during 2003 and spring burning treatments done during 2004 and 2006.

When Joe Sample started posting photos of his takeout food stops in the days after Iowa restaurants were ordered shut down to dine-in service in March, he didn’t think much of it. He just wanted to get some good food while supporting restaurants.

“I have a lot of friends in the food business. My wife worked at Elevate Salon and Emil’s Deli, so she’s not working right now,” he said. “I felt it was a great way to support local businesses.”

But then a new Facebook group dedicated to promoting curbside, delivery and takeout food options in Cedar Rapids sprung up — this week, it had more than 15,000 members — and Sample started sharing photos there. The 46-year-old Cedar Rapids resident quickly found himself having a new experience — going viral.

In a pandemic, that phrase could have negative connotations, but this was the positive kind of viral spread. The kind where hundreds of people liked his photos and commented on them. Then a Cedar Rapids T-shirt maker, Ivory Pearl Designs, started selling “Be Like Joe” T-shirts and other people started showing up to order takeout in the shirts. Soon, restaurants were asking if he would come take a photo at their restaurant.

“I just started it to have fun and posted a few fun pictures, and then I started having restaurants reach out to me,” Sample said.

He decided to dedicate his stimulus check from the federal government to the effort. Sometimes, he said he hits up more than one restaurant a day.

“I’ve hit close to 60 restaurants,” he said.

He’s leaned into the enthusiasm and found ways to play up the efforts. One day he dressed as Oscar the Grouch while visiting’ Oscar’s Restaurant in Hiawatha. On another day, he and one of his daughters bought plastic pig noses to wear on a stop at the Blind Pig in Cedar Rapids. He wears a Superman costume to some stops.

“I was totally surprised at how viral it went,” he said. “Now I’m just trying to keep it exciting.”

In his day job, Sample is a salesman for American Building Components in Mount Pleasant. He normally spends a lot of time on the road, selling metal roofing, siding and steel frame structures around the Midwest. These days, he’s working from home, making sales over the phone instead. He said going out to get carryout is a chance to see other people and get out of the house.

“It brings some normalcy to my life,” he said.

He has two daughters at home, age 9 and 15, and one son, 22. When he’s not eating out, he likes to spend time outdoors with his family, fishing, camping, hunting and coaching soccer. He admits his last name is a bit on-the-nose for his newest hobby.

“A lot of people ask, ‘Is that really even your real name?’” he said with a laugh.

Sample was born and raised in Cedar Rapids, which fuels his desire to support his town.

“My dad had Sample Pharmacies when I was growing up. People helped support us, so I figured it was the least I could do, to support other local businesses,” he said. “I think the biggest thing is, we want to keep them here. There are so many great restaurants in Cedar Rapids, and we don’t want to lose half of them. I’m going to try to keep going with this until they open the places back up, as much as I can.”

He also has helped do deliveries of donated meals to area hospitals and long-term care facilities. That effort started when his younger daughter’s Girl Scout troop had dozens of boxes of unsold cookies and few options to sell them once the pandemic hit. Sample’s family purchased them and sent them to staff at Mercy Medical Center. Since then he’s dropped off boxes of pita, hummus and gyro meat from Pita’z Mediterranean and American Cuisine, trays of cinnamon rolls from Oscar’s and other places.

“People seem to be very supportive in Cedar Rapids,” he said.

He gave a lot of credit to the Cedar Rapids Facebook group, which was started by Lindsay Leahy, Brooke Murphy-Fitzgerald and Shannon Hanson. Others like it have sprung up in Marion, North Liberty and Iowa City.

“I think this has opened a lot of people’s eyes; it has given people an opportunity to try new things,” Sample said. “I’ve seen more restaurants on here than I’d ever tried before.”

He’s also started to promote nonprofits like the Freedom Festival. He is helping sell the $5 commemorative buttons — even though the 2020 festival was canceled, the buttons will help support the organization’s operations. And he helped with a Big Brothers Big Sisters fundraiser, an effort which inspired him so much he signed up as a volunteer.

He said he hopes his efforts, and others like it inspire others to support the community.

“Keep supporting local, do your best to stay healthy, and when restaurants open back up, keep going to them,” he said. “They’re going to need our help for a long time to come.”

IOWA CITY — The University of Iowa on Thursday unveiled new sustainability goals for the next decade that — if accomplished — would cut its greenhouse gas emissions in half from a decade ago and transform the campus into a “living laboratory for sustainability education and exploration.”

But the goals fall short of what a collective of Iowa City “climate strikers” have demanded for more than a year — that the UI end coal burning immediately at its power plant, commit to using only renewable energy by 2030 and unite with the city of Iowa City in a “town-gown” climate accord.

“It’s ridiculous for the UI to announce a 2030 climate plan as it continues to burn coal for years and burn methane-spewing natural gas for decades at its power plant,” said Massimo Paciotto-Biggers, 14, a student at Iowa City High and member of the Iowa City Climate Strike group.

The university’s new 2030 goals piggyback off its 2020 goals, which former UI President Sally Mason announced in 2010 in hopes of integrating sustainability into the campus’ mission.

Her goals included consuming less energy on campus in 2020 than in 2010, despite projected growth; diversifying the campus’ energy portfolio by using biomass, solar, wind and the like to achieve 40 percent renewable energy consumption by 2020; diverting 60 percent of solid waste; reducing the campus transportation carbon footprint with a 10 percent cut in per capita transportation and travel; and increasing learning and research opportunities.

The university, according to a new report made public Thursday, met or surpassed many of those goals — including, among other things, a slight dip in total energy use, despite 15 new buildings and major additions across campus.

The campus also reported 40 percent of its energy consumption comes via renewable energy sources, and it reduced annual coal consumption 75 percent.

As for waste production, the university diverted 43 percent from the landfill and reported diverting 70 percent more waste than in 2010.

In just the first phase, the new 2030 goals — a result of collaboration across campus involving a 2030 UI Sustainability Goal Setting Task Force — involve fewer numbers and hard percentages. Aside from the aim to cut greenhouse emissions by 50 percent compared to a 2010 baseline, the phase one goals aim to:

• Institutionalize and embed sustainability into campus culture, allowing individual units across campus to develop plans to meeting campus sustainability goals.

• Expand sustainability research, scholarship and other opportunities.

• Use the campus as a “living laboratory” capable of improving campus sustainability and ecosystems.

• Prepare students to live and work in the 21st century through sustainability education.

• Facilitate knowledge exchange among the campus community and with the state, nation, and world.

PHASE 2 EXPANDS ON GOALS

As the campus moves into phase two of its 2030 plan, it will expand on first-phase goals by identifying specific and measurable tasks and metrics.

Leadership plans to finalize that second phase later in the fall semester.

“This approach has meant including units engaged in activities such as academics, research, operations, planning, engagement, athletics, and student life,” Stratis Giannakouros, director of the Office of Sustainability and the Environment, said in a statement.

‘Ambitious and forward-looking’

Sen. Joe Bolkcom, D-Iowa City, who serves as outreach and community education director for the UI Center for Global and Regional Environmental Research, told The Gazette the new goals are “ambitious and forward-looking.”

“The new goals will engage students and research faculty to help build a sustainable path for the campus and broader community,” he said.

The university recently made big news on the utilities front by entering a $1.165 billion deal with a private French company to operate its utility system for 50 years. The deal nets the university a massive upfront lump sum it can invest and pull from annually. It gives the private operator decades of reliable income.

And the university, in making the deal, mandated its new provider pursue ambitious sustainability goals — promising to impose penalties if it failed to do so.

In the present invention, one or both of an active wheel or a passive wheel is composed of an eccentric transmission wheel and is combined with a synchronous transmission belt for forming an eccentric wheel transmission wheel series, so that when the feet input forces at different angles from the treadle shafts of the treadles to an active wheel shaft combined on the active wheel through cranks, the active wheel forms different transmission speed ratios relative to the passive wheel according to the treadle angle, and random inward packing is performed to the transmission belt (100) of the engage end of the eccentric passive wheel (413) during the transmission for stabling the operation.

A vehicle powertrain has an engine, a driving shaft having a passage defined therein, a driven shaft, a pump, a hydraulic fluid reservoir, and a CVT. A driving pulley of the CVT includes a fixed sheave and a movable sheave disposed on the driving shaft for rotation therewith, a spring biasing a movable sheave away from the fixed sheave, and a CVT chamber fluidly communicating with the passage of the driving shaft. The pump supplies hydraulic fluid from the reservoir to the passage in the driving shaft. The hydraulic fluid flows from the passage to the CVT chamber to create a hydraulic pressure in the CVT chamber. The hydraulic pressure in the CVT chamber biases the movable sheave toward the fixed sheave.

A belt-type stepless transmission is provided with: an input shaft; an input pulley having a stationary sheave and a movable sheave; a transmission shaft disposed parallel to the input shaft; an output pulley having a stationary sheave and a movable sheave; a belt wound around the input pulley and the pulley; an output shaft disposed coaxially with the transmission shaft; and a cam mechanism having a sheave-side cam which is provided and affixed to the movable sheave and a shaft-side cam which is provided and affixed to the output shaft and causing the sheave-side cam and the shaft-side cam to make contact with each other to thereby enable the transmission of torque between the movable sheave and the output shaft and apply an axial pressing force corresponding to the torque to the movable sheave.

A continuously variable transmission for a vehicle comprises a primary pulley, a secondary pulley, and a belt entrained around both pulleys in an opposite manner between the fixed and movable sheaves thereof. One pulley carries a selectively deployable stop that may be placed into position to mechanically limit the range of motion between the fixed and movable sheaves. This establishes an actual maximum transmission ratio that is larger than the nominal minimum transmission ratio but smaller than the nominal maximum transmission ratio achievable by the transmission during normal operation thereof. When such a transmission is used on a utility vehicle attached to a substance dispensing applicator operatively driven by the vehicle's engine, the application rate stays substantially constant despite changes in engine speed when the user keeps the transmission upshifted to the actual maximum transmission ratio set by the position of the deployed stop.

A belt-type continuously variable transmission for a vehicle includes: a primary pulley including a first fixed sheave fixed to an input shaft, and a first movable sheave relatively non-rotatable and relatively movable in axial direction to the input shaft due to spline-fitting of a female spline formed on an inner circumferential portion thereof to a male spline formed on the input shaft; a secondary pulley including a second fixed sheave fixed to an output shaft in parallel with the input shaft, and a second movable sheave relatively non-rotatable and relatively movable in the axial direction to the output shaft due to spline-fitting of a female spline formed on an inner circumferential portion thereof to a male spline formed on the output shaft; and a transmission belt, the belt-type continuously variable transmission for a vehicle disposed with at least one of a first groove width defining portion disposed on the primary pulley for defining a maximum groove width of the first pulley groove and a second groove width defining portion disposed on the secondary pulley for defining a maximum groove width of the second pulley groove, the first groove width defining portion and the second groove width defining portion being disposed on one shaft of the input shaft and the output shaft, and the other shaft having a uniform shaft diameter in an range of sliding of the first movable sheave or the second movable sheave in the axial direction except a site with the male spline formed, the other shaft being disposed on the opposite side to the one shaft.

An arrangement for supplying oil to a chain drive which drives a transmission oil pump that is axially offset relative to a torque converter and embedded in an intermediate plate in a vehicle having a torque converter. The driven sprocket of the chain drive is supported by a converter neck mounted in a centering plate. A seal is provided between the converter neck and the sprocket and is arranged adjacent the sliding fit between the converter neck and the sprocket. To compensate for the suppression of lubrication of the seal, the neck bearing and the chain drive, a valve is integrated in the intermediate plate, and a duct is provided in the plane, in which the centering plate is screwed to the intermediate plate, such that excess oil flowing from the valve is selectively directed to the seal, the neck bearing and the chain drive.

In a silent chain transmission, noise performance is improved by preventing guide plates of a silent chain from contacting sprocket teeth before the link plates of the chain contact the sprocket teeth. The silent chain transmission comprises a silent chain in engagement with a sprocket. The silent chain comprises guide rows, each having a pair of guide plates and a plurality of middle link plates, and non-guide rows, each having a plurality of inner link plates. An engagement starting point of the middle link plate with a sprocket tooth and an engagement starting point of the inner link plate with the sprocket tooth are set at positions such that the guide plate is prevented from contacting the sprocket tooth before the respective link plates start to engage the sprocket tooth when runout of the chain in the direction of its width occurs.

A chain belt-type continuously variable transmission in which ratchet-type chain belts are wound on driving and driven pulley devices, each of which has a variable diameter, in order to control the shift ratio. Driving belt supports are disposed in a driving pulley device so as to radially contract and expand. Driven belt supports are disposed in a driven pulley device so as to radially contract and expand. Teeth in the front portions of the driving belt supports and the driven belt supports and teeth in the rear portions of the driving belt supports and the driven belt supports are oriented in opposite directions. Front and rear ratchet gears formed on the driving belt supports and the front and rear ratchet gears formed on the driven belt supports are oriented in opposite directions and are arranged in alternating positions without being formed at corresponding positions in a line.

A belt-driven continuously variable transmission having a downsized torque cam assembly for creating forward thrust to push a movable sheave toward a fixed sheave. The belt-driven continuously variable transmission is adapted to output a torque while changing a speed ratio continuously by altering an effective diameter position of a driving belt. The belt-driven continuously variable transmission is comprised of: an output gear, which is fitted onto the rotary shaft of the driven pulley to output the torque while being allowed to rotate relatively; a piston, which is fitted onto the rotary shaft of the driven pulley between the movable sheave and the output gear while being allowed to rotate integrally with the movable sheave and to reciprocate in an axial direction of the rotary shaft, and which increases an internal pressure of the hydraulic chamber by moving toward the movable sheave; and a torque cam assembly, which is interposed between the piston and the output gear, and which pushes the piston toward the movable sheave when the torque transmitted through the driven pulley is increased.

A transmission system for vehicles, including bicycles, is disclosed. The system aligns a chain or other drive means to a center of each of a plurality of provided sprockets, allows for a smaller, lighter and more durable shifter/controller, and reduces various complications associated with cable slack and shifting. A derailleur is provided with linear actuated features to directly translate drive means from one position to another along a desired path.

The present invention is structured by using one or both of an active wheel and a passive wheel being composed of an eccentric transmission wheel and being combined with a synchronous transmission belt for forming an eccentric wheel transmission wheel series, so that in the reciprocal treadle performed by the human's feet, when the feet input forces at different angles from the treadle shafts of the treadles to an active wheel shaft combined on the active wheel through cranks, the active wheel forms different transmission speed ratios relative to the passive wheel according to the treadle angle.

A power transmission belt comprising cord, elastomeric undercord, at least one pair of opposing v-shaped pulley contact surfaces, and having discontinuous fiber embedded in the undercord, some of which protrude from a contact surface. The fiber comprises deformable polymer, such as nylon, and the fiber protrusions are substantially erect with respect to the surface and substantially straight or slightly bowed, especially near the free end, and the fiber protrusions are deformed from an original cross-sectional shape, which may be substantially round or oval or the like, to an elongated, oval, oblong, kidney, or flattened circle shape. The protruding fiber length is at least two fiber diameters.

A continuously variable transmission oil composition comprising a base oil and at least one phosphorous compound in such an amount that the phosphorus in the phosphorus compound accounts for 0.005 to 0.15 mass % of the total mass of the composition and wherein the continuously variable transmission oil composition has a friction coefficient from 0.146 to 0.164 when tested according to ASTM D2714.

Provided is a lubricating oil composition containing a base oil which includes a mineral oil and/or a synthetic oil, and compounded therein, (A) at least one phosphorus-containing compound selected from phosphoric acid monoesters, phosphoric acid diesters and phosphorous acid monoesters, each having a C1 to C8 hydrocarbon group or groups and (B) a tertiary amine compound having C6 to C10 hydrocarbon groups as substituents thereof. The lubricating oil composition provides both a high metal to metal friction coefficient and an excellent wear resistance and is suitably used in a continuously variable transmission.

A transmitter and a receiver for an optical telecommunication system of the WDM type are disclosed. In one aspect, the transmitter uses a chromato-temporal encoder which, with each block of symbols to be transmitted, associates a code matrix, where each element of the matrix corresponds to a wavelength and a use of the channel. The transmitter includes multiple modulators, where each modulator modulates a laser beam at a wavelength during a use of the channel by an element corresponding to the code matrix. The beams modulated in this manner are multiplexed in an optical fiber. Another embodiment using both a wavelength and a polarization encoding is also proposed.

An undersea long-haul transmission system includes an optical fiber transmission span and a coherent detection and digital signal processing module for providing dispersion compensation. The transmission span includes at least one fiber pair comprising substantially equal lengths of a positive-dispersion first fiber and a negative-dispersion second fiber that are configured to provide a signal output at transmission distances greater than 10,000 km, in which the combined accumulated dispersion across the operating bandwidth does not exceed the dispersion-compensating capacity of the coherent detection and digital signal processing module. Further described is a fiber for use in an undersea long-haul transmission span. At a transmission wavelength of 1550 nm, the fiber has a dispersion coefficient in the range of −16 to −25 ps/nm·km, and a dispersion slope in the range of 0.04 to 0.02 ps/nm2·km.
