Letter to the Editor: Obituary for Ted Adams

0

This past Tuesday, the University of California and the City of Davis lost one of our greatest leaders, Ted Adams. I had the privilege of knowing Ted as a student at UC Davis, and directly with his role as Advisor to the Picnic Day Board of Directors, back in the late ‘80s and early ‘90s. I spent 5 years working in various roles with the Picnic Day Board, but my interaction with Ted was richest in my last when I was Chair of the Board. The hardest task to have is to limit the many ways in which Ted influenced in a positive way every individual lucky enough to know him.

As an advisor to the board, Ted was the consummately calm, wise and humorous influence, consistent from year to year. While the event itself is truly student-run, Ted’s influence and ability to inspire both creativity and competence in these young and upcoming students was invaluable. That influence was all the more important because it was so obvious he did this from a place of affection and respect. Each of us became better managers and better people directly because of Ted’s part in our lives.

There are few individuals whom you can call a mentor, or whose lessons are so valuable and influential in your life that you share them with family and especially your own children. As I rear my own teenagers now, I draw from my own experience with Ted to help, and I believe that is the best thanks I can give to Ted for his love and inspiration to me as a student. His lessons and appreciation for action and balance are the best part of what I do today. I am so grateful to have known Ted, and his influence and spirit will carry on through my family and I am certain in myriad others.

Davis Shakespeare Ensemble presents Relapse

It’s the age-old story of boy meets girl, boy falls madly in love with girl, boy then loses girl in a tragic accident. But, if your name happens to be Orpheus and you just so happen to possess a musical talent that would make Kanye West cry humble tears, then you don’t just grieve for the rest of your life à la Nicholas Sparks.

Ancient Greek myths stated that in his despair over the ill-fated death of his true love, Eurydice, Orpheus did what any self-respecting musician would do: He sang songs so sorrowful that it made the gods atop Mount Olympus weep. The Underworld god, Hades, was also won over by Orpheus’ melodies and allowed him to retrieve Eurydice on one condition: He must never turn around to look at her until they reached the land of the living.

Needless to say, Orpheus didn’t exactly follow the rules and all was lost again. But there is a happy ending of a small sort: Orpheus has become one of the most famous Greek myths and has inspired other artists throughout time.

The Davis Shakespeare Ensemble (DSE) is just one of the many who have been moved by Orpheus’s fascinating feats in the name of love. The Davis Shakespeare Ensemble works in Davis and the greater Sacramento area, modernizing Shakespeare’s writings for the general public. It was founded by Gia Battista, Rob Salas and Steph Hankinson when they were students at UC Davis.

“Since then, we have grown into a fully functioning theater company that has also recently become a 501(c)(3) non-profit organization,” Battista said. “We stage full-length productions, run a summer camp for children, and are now starting to ‘tour’ the different venues of Davis, i.e., The Natsoulas Gallery and Rominger West Winery, for Relapse.”

Relapse is the name of the retelling of Orpheus with Shakespearean sonnets of which Battista is deviser, director, and one of the two actors in the production. The show is movement-based, exploring the action of falling as well as the idea of return.

“Relapse means a return or a falling back to something,” Battista said. “It is ultimately the story about a relationship between two people and how it is inevitable that even though a relationship between two may end, that there will be a return, a falling back — in love with another.”

“What’s unique about this show is that it goes after the audience’s senses from multiple angles at once through music, lighting, movement, and text,” said Salas, an actor in the production. “Watching it will be a very exciting and engrossing experience for everyone that attends. I think what will really surprise people is how we will be able to transform the beautiful Natsoulas Gallery and Rominger West Winery into theater spaces.”

In regards to the choice of sonnets that will be used in this retelling, Salas says that the chosen sonnets perfectly integrate into the story of Orpheus and Eurydice.

“I think my favorite is Sonnet 66; it really captures what this show is about for us. It blends a cold, aggressive view on life but also blends it with the possibility of finding liberation from life’s limitations,” Salas said.

The music for this show is composed by Richard Chowenhill, DSE’s resident composer, who made sure that the tunes not only sounded great but worked in beat with the movements and text. Chowenhill graduated from UC Davis in 2010 with a degree in music (emphases in composition and classical guitar performance) and is currently pursuing a Master of Fine Arts degree in music composition and theory at Brandeis University.

“The process, as always, was an intense one. It began with several conversations with Gia, regarding concept and design,” Chowenhill said. “Once Gia solidified our ideas into a working version of the script, I was able to construct a sound world to accommodate the story that Gia was trying to convey in the script and with movement. The music is there not only to illuminate the text, but to complement the movement.”

On April 7, 12 and 14, the show will be at Natsoulas Gallery at 8 p.m. and April 8 and 15 at 7 p.m. On April 13, it will be at Rominger West Winery at 8 p.m. Tickets are $15 for adults, $12 for students/seniors, and $10 for children 12 and under.

Bottles for Poverty recycles for change

One man’s trash may certainly be another man’s treasure. But who would have thought that the weekend’s empty beer bottles and midterm week’s half-crumpled Starbucks doubleshot cans could mean the difference between life and death for kids in a foreign country?

A group of like-minded students on campus has made it its mission to see that your recyclables not only save trees, but are a tangible effort to save lives as well.

Bottles for Poverty is a newly registered campus organization dedicated to raising money to build a school and ultimately promote education in an impoverished part of Ethiopia in the city of Gondar. Members solicit donations of recyclable bottles and cans, which they then exchange for money at recycling centers.

The group finds that education is the best tool for enabling societies to battle lineages of poverty.

“I didn’t know where to start,” said Robel Haile, founder and president of Bottles for Poverty. “The main reason that I wanted to get involved is because I always wanted to help less fortunate kids around the world.”

Haile had various ideas on how to reach his goal, but like many struggling college students, didn’t have the monetary means to do so. Bottles for Poverty stands not only as a physical organization, but also as a metaphor for how substantial change can be rendered via the smallest collective efforts, Haile said.

“I wanted to use recyclables as a way to bring people together to the cause,” Haile said.

The organization’s first project is to raise $24,000 by the end of the academic year to help build a school in Gondar, a city in Ethiopia with a 62 percent illiteracy rate. The group feels that if the upcoming generations are educated, then there is a better chance for the society to begin fixing its own issues, as opposed to waiting for federal aid.

Once the money is raised, it will be given to the American Jewish Joint Distribution Committee to build the school, an organization that has been building schools, wells and providing medical services in Ethiopia for 23 years and around the world for 97 years. The group has currently raised a little over $3,000.

Although most of the officers are managerial economics majors, take similar classes, and spend much time together, they all have different groups of friends and make it a point to share the weight of spreading word about their mutual mission.

“The word ‘position’ is irrelevant in Bottles for Poverty,” said Marketing Director Erica Munoz. “Everyone works together and contributes what they can.”

Bottles for Poverty has received recognition and support beyond the UC Davis campus. It was recently chosen as one of the five recipients of the Blum Center Scholarship for Developing Economies and are currently waiting to hear from other possible donors as well.

“Besides motivating everyone through recyclables, we are continuously working on finding other ways of raising funds,” Haile said.

One such way is by expansion. Bottles for Poverty is currently working on becoming a federally-registered charity. It plans to continue doing community service in the United States and around the world for years to come, but for now asks that students and community members continue using the organization’s small-step blueprint in order to contribute.

Members encourage those interested to “Like” the Bottles for Poverty Facebook page. Alexis Liu, junior sociology major, found out about Bottles for Poverty via Facebook and has been contributing recyclables ever since.

“It came up on my news feed that one of my friends had ‘Liked’ the page, so I clicked on it to check it out and found that it was something I really believed in,” Liu said. “I mean, the money from the recyclables wouldn’t have bought me much, so why not contribute to world change? It just makes sense.”

Bottles for Poverty hosts bottle drives at Primero Grove twice a month and has a pick-up option for students who cannot physically make it to the location. The next drive will be held on April 14 from 9 a.m. to 2 p.m.

UC Davis on the runway

Funmilayo Alabi is one of the students from University of California, Davis showcasing her collection at the Picnic Day fashion show. Alabi, a design major, graduated from UC Davis in Winter quarter 2012.

“I don’t even know where I am at right now; I kind of want to go sit in on some classes,” said Alabi of her life after graduation. Amid this quarter-life crisis of sorts, Alabi prepares to present her collection later this month, even as she is busy searching for internships in the ruthless industry of fashion design.

Alabi, who dreams to work for Marc Jacobs, plans to study abroad in Japan over the coming summer. Her collection titled Milayo is designed with a flair reminiscent of the insouciant street style that is prevalent in Harajuku, Japan’s style capital. In fact, Alabi counts Harajuku as one of her many style inspirations.

Inspired by Alabi’s ancestral tribe, the Yorubas, and the Rio carnival, Milayo embodies an urban safari. “For the past few weeks, I have been adding new garments to the collection. It looks like a crazy, fun carnival,” Alabi said of the collection.

Alabi’s clothes contain elements made of hair and bright fabrics hand-painted with tribal motifs. The collection currently stands at five complete garments and she hopes to add another before the presentation to bring the total to six finished pieces.

In addition to the clothes, the presentation itself promises to be an elaborate affair with tribal face-painted masks, hair embellishments and body paint. “I never want to stop; I like crazy and bizarre things when it comes to fashion,” Alabi said.

She plans to add a vibe of the jungle with her accessories such as beads and shells in the models’ hair. The makeup is inspired by the women of the Yoruba tribe, in which these face masks are considered powerful symbols of femininity.

However, Alabi is concerned that extravagant accessories might make the looks overwhelming, as the garments themselves are dyed in ostensibly bright golds and reds.

Alabi initially planned on creating her own shoes akin to Alexander Wang’s pony hair booties circa 2011. “Well at first I wanted to have my models in no shoes at all, barefoot even — but I need them to be taller than they are now,” Alabi said. ”I’m still debating on adding hair onto the shoe.”

With the fashion show mere weeks away, Alabi seemed more than aware of the time constraint. “I’m freaking out. Where did all the time go?” Alabi said.  Alabi is currently buying more hair for her garments as she experiments with brighter colors and new motifs.

Perhaps the biggest change to be commended is in Alabi’s outlook towards her work itself, which has shifted perceptibly from critical to pride in the collection. “I thought I had a favorite piece from the collection but it keeps changing. I love all of my garments.”

Campus Judicial Report

Stealing swipes
After losing his student identification card, a freshman student found that he was missing multiple Dining Common (DC) swipes. Reports of the missing swipes led to video surveillance of the DC cashiers’ area, which identified a female student.  The identified suspect was then referred to Student Judicial Affairs (SJA) for misappropriation.  In her meeting with a Judicial Officer, the female student denied that she was the student in the videos and stated that she had not swiped in using the other student’s ID card.
Following further review, the referred student was found to be innocent and not in violation of misconduct, so the charges against her were dropped.

Take your own tests
A student was referred to SJA when a teaching assistant noticed that a different student claimed the exam than the student who had turned it in. Students were required to submit and collect their own exams, so this caused the TA to suspect that academic misconduct had occurred.  However, in her meeting with a Judicial Officer, the enrolled student denied that another student had turned in her exam.  Since the identity of the student who had submitted the exam was unknown and there was no way to establish that the enrolled student had in fact had a friend complete her exam, the charges were dropped and the student received an Administrative Notice.  An Administrative Notice is a formal written notice that puts a student officially “on notice” about specific University policies.

Study buddies Two students were referred to SJA when their midterms revealed several identical wrong answers. In their separate meetings with a Judicial Officer, the students stated that they had studied and reviewed sample problems together prior to the exam, and asserted that this was the reason for their shared wrong answers.  The professor accepted this as a valid explanation and both students received Administrative Notices.

News-in-brief: César Chávez event is this Saturday

The city rescheduled the César Chávez Celebration from March 31 to April 7 due to weather. It will be at 11:30 a.m. in Central Park during the Farmers Market.

This free event is sponsored by the City of Davis through the Human Relations Commission. It will take place at the Rotary Stage at the north end of Central Park.

The event will feature music and singing, community group displays and other presentations.

Editorial: We’ll miss you

0

When students went to sign up for Spring quarter classes,  many were distraught in finding the beloved Open Course List was missing. The beautiful page of Courier New allowed students to see all of the classes that were available, and how many seats were available in each class.

The Open Course List has been replaced with the Class Search Tool, which allows students to search for specific classes, but not to see the entire course catalog at once.

We don’t deal with change well, especially when it comes to the already stressful process of registering for classes.

According to Assistant Registrar Barbara Noble, the Open Course List was removed because it was not up to date, and the amount of open seats displayed was not always correct.

With the new Class Search Tool, students can search by specific class or department, and can choose whether they would like to see all classes offered, or just the ones that have open seats.

The Class Search Tool seems more difficult to use, and the page set-up is less straightforward. With the Open Course List, everything was there and there was no need to navigate complicated search tools — all we had to do was press Ctrl + F.

While this change is hard, it seems that the Class Search Tool ultimately provides the same service as the Open Course List.

It may take some getting used to and we’ll always miss the minimalist aesthetic, but this could be the beginning of a beautiful relationship with the Class Search Tool.

Women’s Gymnastics Preview

Teams: UC Davis, Alabama, LSU, Arizona, Iowa, Central Michigan and host Washington.
Where: NCAA Regional — Seattle, Washington
When: Saturday at 4 p.m.

Who to Watch: Junior Katie Yamamura excelled for the Aggies in 2012, landing slots on each roster and winning the Mountain Pacific Sports Federation Gymnast of the Year award. Yamamura’s specialties are the vault and the uneven bars, but she is clearly talented in floor and beam as well.

Did you Know? Tiana Montell is the third freshman in UC Davis history to qualify for the NCAA Tournament. Her teammate Yamamura was the second Aggie to accomplish that feat in 2009.

Preview: UC Davis is sending two accomplished gymnasts to the NCAA Seattle Region Championship this year. Both Katie Yamamura and freshman Tiana Montell will be competing in the All-Around division.

As MSPF Gymnast of the Year, Yamamura certainly poses a threat to the competition. This will be the Palo Alto, Calif. native’s second NCAA appearance; she earned an all-around berth in 2009 and she finished 14th overall.

Yamamura came back from injuries in 2010 to win six MSPF Gymnast of the Week awards. She also impressed at the MSPF Conference Meet last week when she captured first-place in vault, uneven bars and most importantly, all-around gymnast. She tied her personal record, earning a 9.900 on vault and her overall score of 39.225 broke the previous UC Davis all-around record.

Coach John Lavallee has high hopes for Yamamura this weekend: “Katie’s had an exceptional season. If she goes out there and hits all four events she has a very good chance of qualifying for the National Championship.”

Montell is a first-time NCAA qualifier but she enters the meet fresh off of a performance that earned her the title all-conference All-Around champion. She is certainly no stranger to pressure, having earned two state champion titles as a high schooler.

“Tiana’s done an incredible job this year,” said Lavallee. “I’m excited for her to gain experience from this weekend.”

Lavallee is proud to be taking two athletes to the Regional meet this weekend. He is also excited to see how his team progresses next season.

“We’re only losing Erica Van Dyke on uneven bars this year,” he said. “We’re returning a lot of talent and I’m looking forward to next season.”

Column: Trippy

Whenever there is a discussion on the use of psychedelic drugs, such as acid or psilocybin (mushrooms), for medical rather than recreational uses, two polarized opinions tend to appear. One group will always emphasize the dangers of these drugs: They may tell stories about people who had bad trips, or were arrested for acting oddly or violently in public. The other group will then comment on how research shows that these drugs have many medical benefits and few negative side effects. The first group may think that the second are drugged-out hippies or drug addicts trying to justify their habit. The second group may think that the first are parroting DARE propaganda without researching the true science of these compounds.

The truth? As unsatisfying as it is, it’s hard to say. There are interesting clues as well as contradictions. Recent research from London conducted functional MRIs on volunteers after they received an injection of psilocybin, the functional compound in “magic mushrooms,” and found that there were decreases in the activity of the parts of the brain that coordinate the flow of information through the brain, which the researchers said induced a state of “unconstrained cognition.”

However, researchers in Switzerland did similar research except they had the subjects eat the mushrooms and wait for effect onset. They had the exact opposite result from the team in London; those same areas of the brain were activated in their research, rather than reduced as in the London research.

Why would the same drug have the completely opposite effect? One of the obvious differences is that the London researchers injected the psilocybin, which produced an immediate but short “trip,” while the team in Switzerland used the much more common method of eating the mushrooms and waiting for the onset of the effects.
The two most important factors in figuring out the effect of a drug is in the dosage and the rate at which the body processes it. Psilocybin is relatively quickly converted by the body into its active form psilocin, which is what causes the trip. However, even if the absolute dosage of psilocybin is the same for both researchers, eating the mushrooms will cause the compound to be processed by the body much more slowly than injecting the drug. Not only could this change the effect itself, but the methods may also cause different levels of anxiety due both to using a needle and the fact that injecting the drug causes a virtually instant trip, rather than the much more gradual onset of eating the mushrooms.
The most commonly-used psychedelic drugs are psilocybin, lysergic acid diethylamide (LSD, aka acid) and mescaline. Psilocybin and mescaline occur naturally in certain species of mushrooms and cacti, respectively, while LSD is a synthetic drug derived from the fungus ergot. Though these compounds are produced in very different ways, they have similar effects: euphoria, changes in perception and visual and mental hallucinations.
There is a great deal of evidence that there are positive effects of these drugs; for example, psilocybin has been found to decrease symptoms of depression, cluster headaches, obsessive compulsive disorder and anxiety related to terminal cancer. Reports of lethal doses of psilocybin are very rare and the overall toxicity of the drug is very low.
However, people unprepared for its effects can experience panic attacks or nausea. Those side effects may sound inconsequential to people who have never experienced a panic attack, but they pose a real danger to those prone to anxiety.
I do want everyone to understand that just like any other drug, whether it is legally prescribed, illegally obtained or found in nature, there are side effects and consequences. There’s a lot to criticize about the “War on Drugs,” but the legal inconsistencies have made the medical effects of these substances difficult to study reliably.
The unfortunate fact is that legality is rarely a good indicator of how dangerous it is; alcohol and cigarettes are both legal but cause an astonishingly high number of deaths. Legality is also a poor indicator of strength — possession of psilocybin-containing mushrooms is outlawed (with a few exceptions) while the much more intense substance salvia is still legal in most states. The bottom line here is to be careful of what you put in your body, no matter what it is.

Davis Farmers Market Cookbook will be released this Saturday

0
The Davis Farmers Market will celebrate the debut of The Davis Farmers Market Cookbook this Saturday. This event coincides with the official release of the book.

This will be the first of several Market Cookbook Day events to headline the cookbook.

Co-authors Georgeanne Brennan and Ann Evans will be there to sign cookbooks. Customers with cookbook gift cards purchased from the Market can redeem them at the Market Shed. The UC Davis Dining Commons will offer “tastes of cookbook recipes” at each Cookbook Day.

In the book, Winters resident Brennan and former Davis Mayor and food activist Evans praise the Davis Farmers Market and the local food showcased there every week.

The book details eight recipes to adapt to any season, followed by four chapters with each chapter containing about 20 recipes. Alice Waters, Chez Panisse founder and food activist, wrote the book’s foreword.

Davis Farmers Market Manager Randii MacNear said the Market plans to use the cookbook as a platform for events throughout 2012.

“When the cookbook goes on sale April 7, The Davis Farmers Market Cookbook is going to claim a top spot on bookshelves of home cooks and farmers market lovers everywhere,” she said in a press release.

“The Farmers Market has spawned all kinds of side projects, including the school Crunch Lunch program, the RISE (Recycling is Simply Elementary) program in the schools, and much more,” said Davis Mayor Joe Krovoza in an e-mail. “It’s given us a great permanent rain/shade canopy that hosts many other events. The book is just one more example of the FM as a hub of numerous great things.”

MacNear added that this is the first time the Market has launched a cookbook, so this is a big deal for them.

The authors are also signing books and selling the books at the new UC Davis Farmers Market at the campus Silo today. This soft launch will be from 11:30 a.m. to 12:30 p.m.

Other cookbook signings at the Market are: May 26, 10 a.m. to 12 p.m. and June 16, 10 to 11 a.m. Additional signings are scheduled for this fall. The book costs $24.95.

Women’s Tennis preview

Teams: UC Davis vs. Cal State Northridge
Records: Aggies 6-10 (2-2), Matadors 9-6 (2-3)
Where: Marya Welch Tennis Center, Davis
When: Wednesday at 2 p.m.
Who to Watch: Coach Bill Maze has cited singles play as the strength of the Aggies’ women’s tennis team, and sophomore Kelly Chui has been a stronghold in the third singles slot.
Chui has grabbed wins in six of her last seven matches and also is part of UC Davis’s No. 1 doubles pairing.
Did you know? The doubles point is turning out to be a tipping point for UC Davis. The Aggies have won the doubles point only four times this year, and they have emerged victorious each of those times.
Yet, the Aggies have lost four matches by scores of 4-3, and in all of those, they won half of the six singles matches but dropped the doubles point.
“We could have won a couple extra matches if we’d won the doubles point,” Maze said. “I think we’ll get it together before the [Big West] Conference tournament.”
Preview: UC Davis played two matches in Hawaii over spring break in preparation for the difficult schedule ahead.
The Aggies will continue Big West competition today in a matchup with Cal State Northridge.
“We have a hectic schedule in the beginning of the quarter, but I think we’re ready,” Maze said.
Despite the Matadors’ 2-2 league record, they, like the Aggies, are a very dangerous team. CSU Northridge downed a tough UC Santa Barbara team in January, though the match did not affect their conference standing. The Gauchos have since beaten both the Aggies and the Matadors in close matches.
CSU Northridge is coming off a 5-2 defeat to 67th-ranked UC Irvine, another Big West rival. The Matadors’ very strong doubles lineup will provide a challenge for UC Davis, who will find no easy matches on Wednesday.
The Aggies will look to begin their push as they progress later in the season, vying for a top spot in the conference.
“It’s a big match for us because it will affect our seeding in the [Big West] tournament,” Maze said. “We get to play them at home, the team’s looking forward to it and I think we have a great shot.”

Aggies respond at home

After an impressive home stand against conference opponent UC Riverside, the 12-22 Aggies proved that they are a real threat in the Big West Conference.

UC Davis won the bookends of the three-game series against the now 18-17 Highlanders who came into Davis with a five-game win streak. Freshman pitcher Justine Vela was fantastic over the weekend with 20 strikeouts and only two earned runs allowed in the Aggies’ two wins.

Although UC Davis was shutout in the second game, the Aggies furiously responded in the rubber match, winning 9-1 in the shortened five-inning game. The experience from junior Megan Guzman and seniors Kelly Harman and Rachel Miller proved vital as they combined to tally 13 of the team’s 18 hits in the series.

The series win gave UC Davis a 2-1 Big West Conference record to start the league campaign.

Sunday — UC Davis 3, UC Riverside 1

Vela dominated from the start with four straight strikeouts and would not allow a Highlander hit until the sixth inning in the series opener.

The Aggie offense also provided quick run support with freshman Cassandra Ginnis scoring one of her two runs on the day off of a Miller sacrifice fly in the first inning.

Although UC Davis was held to three hits on the day, patience at the plate paid off with the Aggie offense combining for seven walks.

Sunday — UC Riverside 8, UC Davis 0
The Aggies struggled in all aspects of the second game as the offense managed just four hits.
UC Riverside scored four runs over the first four innings to jump out to a 4-0 lead.

Three Aggie errors in the sixth inning errors allowed the Highlanders to stretch their lead to 8-0. UC Riverside was also able to hold off multiple Aggie rally attempts in the fourth and sixth innings to put away the game.

Monday — UC Davis 9, UC Riverside 1
UC Davis wasted no time in the rubber match of the series as Miller, Guzman, and senior Kylie Fan all drove in runs in the opening inning to give the Aggies a commanding 6-0 lead.
The offense would add three more runs by the fourth inning thanks to an RBI double by Miller and an RBI triple by freshman Amy Nunez.
As overpowering as the Aggie offense was, Vela was just as good with six strikeouts and only one earned run on the day as the combined team effort allowed UC Davis to win in only five innings.
“The team really came together in these games,” said Ginnis, “and it showed.”
The Aggies return to action on Friday in an away series against Cal State Northridge.

The nose knows

UC Davis researchers have found a method for using an electronic nose to detect if fruit has fully ripened, which in the future could reduce costs for farmers harvesting crops, as well as give researchers a more objective tool for measuring fruit flavor and maturity.
The electronic nose, called zNose, uses a technique called gas chromatography to separate and identify the chemical compounds that cause aroma in a blended fruit by vaporizing the compounds. Each compound vaporizes at a different time, which allows the user to detect which compounds are present in the juice.
“We use aroma compounds produced by fruits during the ripening process as markers to distinguish between fruits harvested at different maturity stages.” said Simona Vallone, a postdoctoral researcher in the department of plant sciences at UC Davis.
The researchers tested the zNose’s ability to detect the ripeness of melons in a laboratory setting as well as in the field. They found that the technique was able to differentiate between the different stages of maturity.
“The mixture of the aroma compounds are separated [by gas chromatography] so you can look at the composition of the aroma mixture,” Vallone said. “During the fruit ripening process, qualitative and quantitative changes in the aroma profile occur and we use that information to evaluate if the fruit is ripe or not.”
The biggest difficulty the researchers faced was not in using the device, but in the vast amount of data they collected. They soon found that the software provided with the zNose was not able to efficiently process all the information, so coauthor Nathan Lloyd had to program a new one.
“We’re hoping that [Nathan Lloyd’s software program] is going to help other labs who are interested in using the electronic nose,” said Florence Negre-Zakharov, assistant professor of plant sciences at UC Davis and lead author of the paper. “It avoids a lot of caveats of data analysis that you can fall into if you’re not careful with data interpretation.”
Negre-Zakharov said that the research is important for farmers trying to efficiently harvest their fruits.
“For a tomato, it’s easy to see when it ripens,” said Negre-Zakharov. “For something like a melon, it’s not so easy to see.”
Negre-Zakharov also thinks that the technique for using the zNose will also be helpful for researchers in fruit and vegetable breeding programs.
“The breeders often rely on visual characteristics, some taste their fruit, but they don’t really have an objective measure of the quality of their fruit,” Negre-Zakharov said. “This technology could be used as a more objective assessment of flavor quality.”
The research was funded in part by the US Department of Agriculture (USDA) in a program seeking to increase consumption of fruits and vegetables by improving their quality and safety. The project is a collaboration between UC Davis, the USDA and the University of Florida. Funding was also provided by the seed technology company Harris-Moran, which grew the melons the researchers used for the research.
The zNose was developed by Electronic Sensor Technology, Incorporated from Newbury Park, Calif. Ken Zeiger, a sales and marketing representative from Electronic Sensor Technology, Inc. says that UC Davis is one of several research institutions that are looking at the zNose for food science applications.
“I’ve been working with several people in that area,” Zeiger said. “We’ve been testing everything from melons to onions, and we’re waiting for the results on that. Basically, we have a very sensitive, portable gas chromatograph.”
Ultimately, Negre-Zakharov considers this technology “pretty cumbersome, but feasible compared to the machines we use on a regular basis for our research.”
She and the other researchers hope that the technology will continue to develop, becoming more portable and affordable so that fruit and vegetable quality will improve.

Symposium to be held in observance of National Public Health Week

0
Aside from being the start of Spring Quarter, this week is also National Public Health Week.

The UC Davis Department of Public Health Sciences is observing National Public Health Week by sponsoring a symposium on campus this Thursday.

Keynote speaker Ron Chapman, Director and State Health Officer for the California Department of Public Health, will be discussing health equity in California.

“We hope this event will bring awareness to public health and teach our guests about the different avenues of public health,” said Crystal Saetern, student affairs officer for the UC Davis Master of Public Health Program.

Student Affairs Officer Amber Carrere agreed.

“A lot of students don’t know what’s happening in public health,” Carrere said. “It’s a good time to showcase what’s going on, not only in the state, but locally as well.”

Organized since April 1995 by the American Public Health Association, the week-long awareness event aims to highlight issues and bring recognition to contributions to public health.
