Arkansas 4-H teams design, build, pilot submersible robots in SeaPerch Challenge


BRYANT — As a crucial device of area expedition as well as deep-sea research study, robotics is an important area in the future of scientific research. Forty groups placed their robotics expertise to the examination at the 2022 Arkansas SeaPerch Obstacle on April 11 at the Facility at Diocesan Park in Bryant.

At the occasion, organized by Arkansas 4-H as well as the Electric Cooperatives of Arkansas, junior as well as secondary school pupil groups guided their from another location run cars via 2 undersea difficulty programs as well as addressed meeting inquiries from courts.

The total winning junior, elderly as well as open groups will certainly head to the International SeaPerch Obstacle at the College of Maryland on June 4. The Trumpinators – Colton Edwards as well as Trevor Edwards of Madison Region – are the winning elderly group, as well as their instructor is Darrin Henderson. The winning junior group is the Wave Shockers from Give Region: Jaxson Andrews, Luke Douthit, Kaylynn Cogbill as well as Martin Nash, with instructor Brad McGinley. The winning open group is BZBot2 from Washington Region: Ash Timber as well as Ryuji Adhryan, with instructor Len Timber.

Groups created their completely submersible robotics utilizing greater than 3 loads components, consisting of PVC pipelines, items of swimming pool noodle, props, 3 12-volt electric motors as well as batteries. At each difficulty terminal, 2 participants from each group were entrusted with guiding the robotic via the program as well as taking care of the rope or cable connected to the robotic. In the barrier program, rivals needed to browse their robotics via a collection of plastic hoops put at various angles. The objective program, made to replicate area expedition, evaluated the robotics’ capacities to grab as well as relocate things.

Groups were timed throughout their development via the programs, with courts at each terminal score their efficiency. The groups were likewise racked up on their technological records for the job, as well as on their design note pads, which they sent beforehand. These note pads record the design procedure throughout the develop of each group’s ROV as well as were consisted of in the evaluating as well as total group positions.

Lori Canada, expansion 4-H STEM planner for the College of Arkansas System Department of Farming, claimed the competitors involved pupils throughout several abilities.

“It was a terrific day to have the Arkansas 4-H SeaPerch occasion at the Bryant Parks as well as Entertainment Facility at Diocesan Park,” Canada claimed. “Lots of many thanks to our enroller Electric Cooperatives of Arkansas for sustaining our program. This is a terrific chance for young people to find out as well as expand in even more abilities than simply design. Via the SeaPerch program, individuals method vital reasoning, analytic, discussion abilities therefore far more. Congratulations to all groups that joined this year’s competitors.”

The competitors likewise consisted of a meeting, throughout which courts examined individuals regarding their style procedure, competitors objectives as well as specific duties in their robotic’s building. Groups were ranked on their engineering style procedure, their company as well as imagination, as well as the self-confidence as well as quality of their discussion throughout the meeting.

Arkansas lands Courtney Crutchfield


Pine Bluff native and Missouri transfer wide receiver Courtney Crutchfield signed with Arkansas on Wednesday.

The former four-star recruit announced his intentions to enter the transfer portal last Thursday and he officially entered last Friday. Crutchfield redshirted this season for the Tigers.

A 6-foot-2, 188-pound pass catcher, Crutchfield recorded 42 receptions for 930 yards and 13 touchdowns his senior season at Pine Bluff. He was committed to Arkansas for nearly seven months before eventually signing with Missouri.

Crutchfield will have four years of eligibility remaining. He was rated by Rivals as the No. 2 overall recruit and No. 1 wide receiver in the state of Arkansas in the 2024 recruiting class.

FDA phasing out ineffective decongestant | Arkansas Democrat Gazette

FDA phasing out ineffective decongestant | Arkansas Democrat Gazette


WASHINGTON — U.S. officials are moving to phase out the leading decongestant found in hundreds of over-the-counter medicines, concluding that it doesn’t actually relieve nasal congestion.

Phenylephrine is used in popular versions of Sudafed, Dayquil and other medications, but experts have long questioned its effectiveness. Last month, the Food and Drug Administration formally proposed revoking its use in pills and liquid solutions, kicking off a process that’s likely to force drugmakers to remove or reformulate products.

It’s a win for skeptical academics, including researchers at the University of Florida who petitioned the FDA to revisit the drug’s use in 2007 and again in 2015. For consumers, it will likely mean switching to alternatives, including an older decongestant that was moved behind the pharmacy counter nearly 20 years ago.

Doctors say Americans will be better off without phenylephrine, which is often combined with other medicines to treat cold, flu, fever and allergies.

“People walk into the drugstore today and see 55,000 medicines on the shelf, and they pick one that is definitely not going to work,” said Dr. Brian Schroer of the Cleveland Clinic. “You take away that option, and it will be easier for them to self-direct toward products that really will help them.”

The FDA decision was expected after federal advisers last year voted unanimously that oral phenylephrine medications haven’t been shown to relieve congestion.

Experts reviewed several recent, large studies indicating that phenylephrine was no better than a placebo at clearing nasal passageways. They also revisited studies from the 1960s and 1970s that supported the drug’s initial use, finding numerous flaws and questionable data.

The panel’s opinion only applied to phenylephrine in oral medications, which account for roughly $1.8 billion in annual U.S. sales. The drug is still considered effective in nasal sprays, though those are much less popular.

Phenylephrine wasn’t always the top choice for cold and allergy products. Many were originally formulated with a different drug, pseudoephedrine.

But a 2006 law required pharmacies to move pseudoephedrine products behind the counter, citing their potential to be processed into methamphetamine. Companies such as Johnson & Johnson and Bayer decided to reformulate their products to keep them readily available on store shelves — and labeled many of them as “PE” versions of familiar brand names.

PHARMACY NEEDED

Consumers who still want to take pills or syrups for relief will probably need to head to the pharmacy counter — where the pseudoephedrine-containing versions of Sudafed, Claritin D and other products remain available without a prescription. Purchasers need to provide a photo ID.

Beyond those products, most of the other options are over-the-counter nasal sprays or solutions.

Saline drops and rinses are a quick way to clear mucus from the nose. For long-term relief from seasonal stuffiness, itching and sneezing, many doctors recommend nasal steroids, sold as Flonase, Nasacort and Rhinocort.

“These medicines are by far the most effective daily treatment for nasal congestion and stuffiness,” Schroer said. “The biggest issue is they’re not great when used on an as-needed basis.”

Nasal steroids generally have to be used daily to be highly effective. For short-term relief, patients can try antihistamine sprays, such as Astepro, which are faster acting.

Phenylephrine-based sprays will also remain on pharmacy shelves.

SWALLOWING STIFLES AID

The experts who challenged the drug’s effectiveness say it’s quickly broken down and rendered ineffective when it hits the stomach.

“This is a good drug, but not when it’s swallowed,” said Leslie Hendeles, professor emeritus at the University of Florida’s College of Pharmacy, where he co-authored several papers on the ingredient. “It’s inactivated in the gut and doesn’t get into the bloodstream, so it can’t get to the nose.”

When Hendeles and his colleagues first petitioned the FDA on phenylephrine, they suggested a higher dose might be effective. But subsequent studies showed that even doses 400% higher than those currently recommended don’t treat stuffiness.

The FDA and other researchers concluded that pushing the dosage even higher might carry safety risks.

“If you’re using very high doses, the risk is raising blood pressure so high that it could be hazardous to patients,” said Randy Hatton, a University of Florida professor who co-led the research on phenylephrine.

Because of its cardiovascular effects, the drug is sometimes used to treat dangerously low blood pressure during surgery, Hatton noted.

Sam Pittman breaks down Arkansas' biggest transfer portal needs


With the transfer portal in full swing, Arkansas coach Sam Pittman addressed some of the biggest areas of need for his team. The Razorbacks are coming off of a 6-6 finish in the fifth year under Pittman and looking to boost their roster for another run in 2025.

Speaking with media, Pittman highlighted both the offensive and defensive line as the areas where Arkansas needs to be most aggressive in the portal. He also cited the linebacker group as a the position that the team feels best about, saying the Razorbacks will look to improve its defensive backs room first.

“Offensive line would be one (area of need),” the coach said. “Defensive line would be one. We felt like we were pretty good at the linebacker spots. If you go back and look a couple of years ago, the world was falling because this linebacker (left), that linebacker (left).

“I think we all agreed out linebacker room was a strength for us this year. But that would be probably the least worried about (position). We need some safeties. We need some corners. But I think O-line and tight end’s a big deal. Wide receivers. We’ve got several spots to fill, but off the top of my head, that’s who it would be.”

Since Pittman’s comments, Arkansas has been active in the transfer portal to bring in 13 players. Unfortunately, they’ve also lost 26 more and rank just No. 59 out of 70 teams in On3’s Transfer Portal Team Rankings.

Staying true to to his word, Pittman has brought in four offensive linemen and a pair of defensive lineman through the portal. Former Georgia Tech offensive tackle Corey Robinson II is the highest rated of those additions, coming in as the No. 32 overall player and No. 5 player at his position according to On3’s Transfer Portal Player Rankings.

Arkansas also brought in former Charlotte receiver O’Mega Blake and former Cincinnati cornerback Jordan Young to give it three players ranked in the top 150.

The Razorbacks still have a long way to go to complete their portal class, likely hoping to add some more defensive linemen before it closes later this month. They are looking to make the next push in the SEC next season and the players they’ve gotten so far are a good start.
