The distribution of a forest decline of yellow-cedar (Callitropsis nootkatensis (D. Don) Orsted) has been documented in southeast Alaska, but its occurrence in British Columbia was previously unknown. We conducted an aerial survey in the Prince Rupert area in September 2004 to determine if yellow-cedar forests in the North Coast Forest District of British Columbia were experiencing a similar fate as in nearby Alaska. Numerous large areas of concentrated yellow-cedar mortality were found, extending the known distribution of the decline problem 150 km south of the Alaska-British Columbia border. The forests with the most concentrated tree death occurred at 300 to 400 m elevation, frequently on south aspects. The appearance of these forests including proximity to bogs; mixtures of dying, recently killed, and long-dead trees; and crown and bole symptoms of dying trees were all consistent with the phenomenon in southeast Alaska.

Four types of tree shelters were evaluated in southwestern Washington for their effects on seedling microenvironment and performance of two tree species. Shelter types were fine-mesh fabric shelters, solid-walled white shelters with and without vent holes, and solid-walled blue unvented shelters. Summer mean and daily maximum air temperatures were increased by 0.8 degrees C and 3.6 degrees C, respectively, in solid-walled tree shelters. Shelter color and shelter venting did not influence air temperatures. Tree shelters only affected vapor pressure deficit late in the growing season. Midday photosynthetically active radiation within shelters ranged from 54 percent of full sun in fine-mesh fabric shelters to 15 percent of full sun in blue solid-walled shelters. In the first year after planting, height and diameter growth of western redcedar (Thuja plicata Donn ex D. Don) were significantly increased by all shelter types, with blue solid-walled shelters resulting in the greatest height growth. However, in blue solid-walled shelters, photosynthesis and stem diameter growth of Oregon white oak (Quercus garryana Dougl. ex Hook.) seedlings were significantly less than for unsheltered seedlings.

From May 24-28, 2010, an international symposium on western redcedar (Thuja plicata) and yellowcedar (Callitropsis nootkatensis [syn., Chamaecyparis nootkatensis]) was held at the University of Victoria on Vancouver Island in British Columbia, Canada. The symposium was entitled "A Tale of Two Cedars" and brought together local, regional, national, and international experts to present cultural, biological, management and economic information on the two species. Although some papers or posters focused on just one of the cedars, many of the presenters covered both species and discussed the similarities and differences between them. This proceedings includes abstracts or short papers from all of the formal presentations or posters presented at the symposium.

None of several types of chemotherapeutants applied before inoculation (antibiotics, metallic salts, systemic fungicides) prevented infection of sugar pine seedlings by white pine blister rust. DMSO (dimethyl sulfoxide) did not enhance the action of any material with which it was applied.

The U.S. Forest Service's Pacific Northwest Research Station today released a new report that outlines a climate adaptation strategy for yellow-cedar in Alaska.

On February 4, 2014, a seven-member expert panel provided objective technical information on the potential effectiveness and feasibility of activities to manage raptors (northern harriers and great horned owls) to aid the recovery of western snowy plovers.

A conservation and management strategy for yellow-cedar in Alaska is presented in the context of climate change.

The City of Cedar Rapids Thursday morning issued a drinking water boil order for portions of southwest Cedar Rapids.

A rupture in a water main feeding the Bowling Street Booster Station and C Street Water Tower caused a loss of pressure, which created the potential for bacteria contamination to occur, according to a news release.

The two affected areas are bounded by these streets:

• For the first area, Schaeffer Drive SW east to C Street SW and 19th Avenue SW south to Highway 30.

• For the second area, Sixth Street SW east to J Street SW and 29th Avenue south to 36th Avenue SW.

The city is advising affected residents to:

1) Bring water to a boil

2) Let it rapidly boil for at least 1 minute

3) Allow to cool completely before consuming

The boil order should be lifted or extended by 1 p.m. Sunday, after repairs are complete, pressure is restored, flushing has occurred, chlorine levels have been monitored and two consecutive sets of bacteria samples have been collected for analysis, the city stated.

Water is safe to consume in all other areas of Cedar Rapids.

On Wednesday, Gov. Kim Reynolds removed some restrictions on businesses in the 22 counties that have been seeing higher numbers of Iowans affected by COVID-19, including Linn and Johnson counties.

Now those organizations have to make decisions — on bringing back employees, services to provide and how much access to allow for customers.

And as those businesses reopen — some after more than two months — crucial steps likely will include ongoing communication with employees and customers and a well-thought-out restart plan.

The Gazette spoke with business leaders about the challenges faced by business owners as they consider how and when to open their doors.

• David Drewelow of ActionCoach Heartland in Cedar Rapids is a consultant with 19 years of business coaching experience.

• David Hensley, director of the University of Iowa’s John Pappajohn Entrepreneurial Center, has expertise in small business management during a crisis.

• Josh Seamans is vice president of Cushman and Wakefield, a global commercial real estate adviser that operates offices in more than 60 countries including China.

• Steve Shriver is a Cedar Rapids entrepreneur who operates and/or helped found four diverse enterprises, including Eco Lips and Brewhemia.

Their responses here have been condensed from lengthy individual interviews.

How important is communication and having a well-prepared plan for resumption of business?

Shriver: The one thing that has been imperative throughout this whole process is communication with employees, customers and the public. I also would recommend writing as detailed a business resumption plan as possible.

One of the main reasons is to fully understand what you are doing as this is a brand-new challenge that none of us has faced.

Drewelow: You really need to be communicating now, more than ever, with your employees, customers, vendors and suppliers. What does your plan for the next 20 to 30 days look like? What are things that you can be doing right now to get ready?

Hensley: I think it is critically important to have a reopening plan because most businesses are not going to be at full strength right away. What might their revenue forecasts look like? How can they keep their costs down as their business starts to rebound before it gets back to full capacity?

Seamans: Your plan should include a checklist of reopening steps appropriate to your type of business. Retail will have different items than distribution or industrial businesses.

You need to communicate your plan to employees, customers, landlords and lenders.

How much will fear play a role in the resumption of business?

Shriver: Everyone has a different idea of the risks involved, such as using a handle to open a door or interacting with a person — the little things that we are used to doing.

When you look at the risk versus reward of doing that, some people will be willing to go into a store and others will stay home. Some employees don’t want to come back to work yet and some people are itching to get back. You have everything in between.

Drewelow: The fear factor is huge. For the small business owner, we try to channel that fear into a focus on being highly aware of all the possibilities to mitigate concerns.

If you own a restaurant, can you post the menu online or use disposable menus? That way, a customer doesn’t have to touch something that might have been handled by someone else.

Appropriate spacing of customers within a restaurant also will help alleviate some of the fear.

Hensley: You need to communicate what steps you are taking to protect the health and safety of your employees and your customers. If you will be requiring the use of personal protective equipment like face masks, are you going to make them available?

Will limiting the number of people entering a business be difficult?

Shriver: There are not a lot of people who want to gather in masses right now. It seems like as businesses start to reopen, it will be more like a trickle.

It will be just like turning on a water spigot, with the flow of customers gradually increasing.

Hensley: I think we will see a lot more customers buying, rather than just shopping. They are going to buy the items they came for and then leave.

If businesses have more vulnerable customers, I would recommend establishing separate early morning times like many of the grocery stores have done to provide a safer environment.

Many companies have adopted using digital conferencing platforms for meetings. Will we see that trend continue?

Seamans: I think Zoom will be used for more internal meetings, so there is no need for someone to fly from, say, San Francisco to New York. But in terms of sales, it does not replicate that face-to-face interaction.

We have done work with clients that live several hours away and we have to come in for a city council meeting for a project that we are working on. That’s a three-hour drive in for a one- or two-hour council meeting and another three-hour drive back — basically an eight-hour day. If we can Zoom in and answer any questions, that’s a lot more efficient at less cost.

What should a small-business owner consider when determining how many employees to recall?

Shriver: We will be able to bring some people back to work and generate some revenue, but not in a huge way. Anybody who can work from home should continue working from home for as long as they possibly can.

We should not be rushing to get those people back. There is no incentive.

Hensley: Owners are going to be making hard decisions. Do I bring back half of my team at full time or do I bring everyone back at reduced hours? What are those implications going to be?

In some cases, other industries have been hiring and some may be making more money. Businesses may have to pay more to attract that talent back.

Restaurants have been forced to change their business model from on-premise dining to carryout and delivery. Should all owners take this opportunity to examine and update their business model?

Shriver: We took two businesses — SOKO Outfitters, a retail store, and Brewhemia, a restaurant — and put them rapidly online within a month. When we come out of this, I think we will be stronger because we will have that infrastructure in place in addition to the old school face to face traffic that we used to have.

Hensley: I think this is definitely the time to look at your business model to determine what is appropriate given the economic situation that we have. That is not just going to be critical for reopening, but over the next six months to a year as long as we are dealing with the virus.

Some business owners will see that their customers have lost their jobs or seen their income drop dramatically. They are going to be changing their patterns of consumption based on necessities.

Drewelow: Some of my clients believe that are looking their competitors and realize that some may not reopen. They are looking at whether they can merge with them or somehow salvage parts of that business.

Some business owners have realized that the way they deliver products or services will have to change. Many of my older clients have been dragged into using modern technology.

CEDAR RAPIDS — A 32-year-old Cedar Rapids man, who received probation for a high-speed chase that he bragged about as “fun” and attempted to elude again in March, is heading to prison.

Sixth Judicial District Judge Lars Anderson on Friday revoked probation for Travis McDermott on the eluding charge from June 9, 2019, and sentenced him to five years in prison.

McDermott was convicted Tuesday for attempting to elude in March and was sentenced to 90 days in jail, which was run concurrently to the five-year prison sentence.

First Assistant Linn County Attorney Nick Maybanks told the judge that McDermott has a “significant violent history,” including assaults, assault on a peace officer, domestic assault, interference with official acts and child endangerment with bodily injury.

He continues to assault others and “show blatant disregard for authority figures,” the prosecutor noted.

In the eluding incident from last June, McDermott “risked lives” in a southwest neighborhood leading police on chase that began on when police saw his vehicle speeding on Rockford Road SW and run a stop sign at Eighth Avenue SW, Maybanks said Friday. McDermott drove 107 mph in a 30 mph zone and drove the wrong way on a one-way street at Third Street and Wilson Avenue SW.

McDermott ran into a pile of dirt at a dead end, jumped out of his car and led officers on a foot chase, Maybanks said. He wouldn’t stop, and officers used a Taser to subdue him.

McDermott was laughing when police arrested him, saying “how much fun” he had and appearing to be under the influence of drugs or alcohol, Maybanks said.

McDermott demanded a speedy trial, but the officer who conducted the sobriety test wasn’t available for trial. A plea was offered, and the drunken driving charge was dropped.

Maybanks also pointed out McDermott wouldn’t cooperate with the probation office on a presentencing report, which was ordered by a judge. He picked up an assault charge last November and was convicted before his eluding sentencing in January.

Maybanks said after McDermott received probation, he didn’t show up at the probation office for his appointment, didn’t get a substance abuse test as ordered and reported an invalid address to community corrections.

McDermott also has a pending charge in Dubuque County for driving while barred March 3, according to court documents.

CEDAR RAPIDS — An injured pelican rescued at Cedar Lake on Wednesday will have a permanent home at one of the top zoos in the Midwest.

“We downloaded all of the paperwork (on Friday), and we want to get it transported (to Henry Doorly Zoo and Aquarium in Omaha) within a week,” said Tracy Belle, founder and director of Wildthunder Wildlife and Animal Rehabilitation and Sanctuary in Independence.

“It’s doing well — we’re going to get it outside today to decompress a little.”

Belle, who also serves as primary animal rehabilitator at Wildthunder, believes the pelican is young — the average life span is 20 to 25 years — and she is not sure of its gender.

It suffered broken carpal bones and, according to Belle, surgical repair is unlikely.

“The veterinarian told me that the injury appears to be five to six weeks old,” she said. “I can only speculate, but I think when it flew into the lake, it may have clipped a power line.”

Belle said the pelican will need one more veterinary exam before transport to Omaha. In the meantime, “its appetite is good,” she said. “It’s eating five to 10 pounds of fish per day.”

Henry Doorly is closed due to the COVID-19 pandemic. In a typical year, the complex attracts about 2 million visitors.

Diagnosis of high impedance fault (HIF) is a challenge for nowadays distribution network protections. The fault current of a HIF is much lower than that of a normal load, and fault feature is significantly affected by fault scenarios. A detection and feeder identification algorithm for HIFs is proposed in this paper, based on the high-resolution and synchronous waveform data. In the algorithm, an interval slope is defined to describe the waveform distortions, which guarantees a uniform feature description under various HIF nonlinearities and noise interferences. For three typical types of network neutrals, i.e.,isolated neutral, resonant neutral, and low-resistor-earthed neutral, differences of the distorted components between the zero-sequence currents of healthy and faulty feeders are mathematically deduced, respectively. As a result, the proposed criterion, which is based on the distortion relationships between zero-sequence currents of feeders and the zero-sequence voltage at the substation, is theoretically supported. 28 HIFs grounded to various materials are tested in a 10kV distribution networkwith three neutral types, and are utilized to verify the effectiveness of the proposed algorithm.

E16), wherein at least two groups (5, 6) of electrodes located next to each other are formed and the electrodes of one group are contacted with at least one, multiwire feed cable (7, 8). For a reduced noise level during data acquisition, provisions are made for at least one electrode (E9) of two mutually adjacently located electrodes (E8, E9) of two different groups (5, 6) to have an additional electrode feed line (15), which is led over the feed cable (7) of the adjacent group (5).

A device and method for accurately characterizing tissue impedance employs multiple electrodes at a plurality of separation distances to cancel the effects of front end loading leakage currents and electrode polarization to improve the accuracy of sensitive impedance measurements used to identify cancerous tissues.

A device is described for measuring electrical characteristics of biological tissues with one or a plurality of electrodes and a processor controlling the stimulation and measurement in order to detect the presence of abnormal tissue masses in the breast and determine probability of tumors containing malignant cancer cells being present in a breast. The device has the capability of providing the location of the abnormality, at least to the quadrant. Either single or multiple source electrodes can be used. Either palpable lumps can be evaluated or screening or breasts, whether with palpable masses or not, can be accomplished. The method for measuring electrical characteristics includes placing electrodes and applying a voltage waveform in conjunction with a current detector. A mathematical analysis method is then applied to the collected data, which computes spectrum of frequencies and correlates magnitudes and phases with given algebraic conditions to determine mass presence and type.

The systems and methods of the present disclosure calibrate impedance loss model parameters associated with an electrosurgical system having no external cabling or having external cabling with a fixed or known reactance, and obtain accurate electrical measurements of a tissue site by compensating for impedance losses associated with the transmission line of an electrosurgical device using the calibrated impedance loss model parameters. A computer system stores voltage and current sensor data for a range of different test loads and calculates sensed impedance values for each test load. The computer system then predicts a phase value for each load using each respective load impedance value. The computer system back calculates impedance loss model parameters including a source impedance parameter and a leakage impedance parameter based upon the voltage and current sensor data, the predicted phase values, and the impedance values of the test loads.

An improved drum pedal for use with an acoustic or electronic bass drum has sprocket wheel 78 mounted for rotation on the toe end of a foot pedal 16. A rotational torque applied to a sprocket 72 attached to a crossarm 22 and in turn to a mallet head 28 causes mallet head 28 to swing through an arc 3 toward the drum head. Sprocket 72 and sprocket wheel 78 are connected by chain 76 in a compound pulley system wherein chain 76 is attached at one end to sprocket 72 and is wrapped around and under sprocket wheel 78 to be fixed at its other end at mounting bar 80, so that a downward motion of foot pedal 16 and sprocket wheel 78 through arc 2 moves sprocket 72 and mallet head 28 through arc 3, which motion is twice the magnitude in distance and velocity as that of sprocket wheel 78.

A pedal mechanism for a bass drum, including a pivoted primary platform connected to a beater ball so that, when the primary platform is depressed, the beater ball moves to contact a drum; and a resiliently mounted secondary platform in operative contact with the primary platform, the arrangement being such that, in use, the toe of the drummer depresses the primary platform directly and the heel of the drummer depresses the primary platform through the secondary platform.

A pedal assembly for a bass drum or high hat cymbals. A flat base plate has a resilient pedal board clamped to it with the pedal board inclined to receive a foot. A beater stick is connected with the toe end of the pedal board by a linkage that drives the beater stick against a bass drum when the pedal is depressed. The resiliency of the pedal board returns it to its normal position when foot pressure is withdrawn. The material of which the pedal board is constructed has a modulus of elasticity between about one million and about six million. A striker pad limits the depression of the pedal board to limit the force that the beater stick can apply to the drum.

Described is a bass drum foot pedal having a variable drive lever linkage with variable arc ratios connecting the foot pedal to a beater bracket. The beater bracket is formed with a mounting surface that tips a beater shaft forward to create a forward beater angle that maximizes the beater impact against a bass drum.

The processor is coupled to the RF front-end circuit and controls the switch modules. In a comparison mode, the switch module selects to connect to the branch circuits individually, and the processor detects each RSSI (Received Signal Strength Indications) value corresponding to the branch circuit and records all of the RSSI values to the storage device respectively. In the comparison mode, the processor further compares the RSSI values to for highest one. Finally, the switch module selects the branch circuit corresponding to the highest RSSI value as a transmission branch.
