Fruit flies could hold the key to building resiliency in autonomous robots - Technology Org

Fruit flies could hold the key to building resiliency in autonomous robots - Technology Org

Mechanical Engineering Assistant Professor Floris van Breugel has been awarded a $2 million National Science Foundation (NSF) grant to adapt autonomous robots to be as resilient as fruit flies.

Resiliency in autonomous robotic systems is crucial, especially for robotics systems used in disaster response and surveillance, such as drones monitoring wildfires. Unfortunately, modern robots have difficulty responding to new environments or damage to their bodies that might occur during disaster response, van Breugel wrote in his grant application. In contrast, living systems are remarkably adept at quickly adjusting their behavior to new situations thanks to redundancy and flexibility within their sensory and muscle control systems.

Scientific discoveries in fruit flies have helped shed light on how these insects achieve resiliency in flight, according to van Breugel. His project will translate that emerging knowledge on insect neuroscience to develop more resilient robotic systems.

“This is a highly competitive award on a topic with tremendous potential impact, which also speaks of the research excellence of the investigator and Mechanical Engineering at UNR,” Petros Voulgaris, Mechanical Engineering department chair, said.

This research aligns with the College of Engineering’s Unmanned Vehicles research pillar.

Engineering + flies

The intersection of engineering and flies long has been an interest to van Breugel.

“As an undergrad, I did research where my main project was designing a flying, hovering thing that birds or insects vaguely inspired,” he said. “Throughout that project, I realized that the hard part, which was more interesting to me, is once you have this mechanical thing that can fly, how do you control it? How do you make it go where you want it to go? If it gets broken, how do you adapt to that?”

Van Breugel says he is examining how “animals can repurpose or reprogram their sensorimotor systems ‘on the fly’ to compensate for internal damage or external perturbations quickly.”

Working with van Breugel on the grant are experts in insect neuroscience, including Michael Dickinson, professor of bioengineering and aeronautics at the California Institute of Technology (and van Breugel’s Ph.D. advisor) as well as Yvette Fisher, assistant professor of neurobiology at U.C. Berkeley. Both have pioneered aspects of brain imaging in flies in regards to the discoveries and technology in the field that van Breugel is utilizing in this research project. Also on the project: Bing Bruton, associate professor of biology at the University of Washington, who brings her expertise in computational neuroscience.

The importance of flies in the realm of both engineering and neuroscience stems from the combination of their sophisticated behavior together with brains that are numerically simple enough that they can be studied in detail. This “goldilocks” combination, van Bruegel said, makes it feasible to distill properties of their neural processing into fundamental engineering principles that can be applied to robotics systems.

As part of the grant, research experiences will be offered to middle school, high school and undergraduate students to participate in both neuroscience and robotics research. Van Breugel and his team also will develop open-source content to help bring neuroscience fluency to engineering students. This aligns with the College of Engineering’s Student Engagement operational pillar.

Traumatic Brain Injury Lawyer: Seek Justice and Compensation

TBI injury is some of the worst kinds of accident injury you can get. If someone else’s carelessness caused you or a loved one to get a traumatic brain injury, you will need the help of an experienced personal injury lawyer who can figure out if you are eligible and make sure you get fair pay for the harm that you or the other person has gone through.

An experienced TBI lawyer will know how to talk to doctors and other experts to assist the court get a clear picture of how bad your traumatic brain injuries are. Before you accept a settlement from an insurance company, you should talk to our trusted expert. Some steps our lawyer takes with your TBI injury case:

The First Step – If you have a traumatic brain injury, you should talk to or hire a personal injury lawyer right away so that the lawyer can start working on your claim and help you get better as soon as possible. During the first meeting, the lawyer and the client can look into the claim, figure out the many things that go into judging the claim, and talk about how the claim will proceed forward.

The Value of Experience – Anyone meeting with a traumatic brain injury lawyer should ask about the attorney’s experience with comparable claims and the jurisdiction where the incident occurred. Traumatic brain injuries are hard to explain to jurors. Thus, a personal injury attorney’s expertise in the damage and jury presentation experience should reassure clients. The person should be confident that their traumatic brain injury lawyer is optimal for their case. Attorneys know that traumatic brain injuries can affect the victim and their family for life. Lawyers feel that traumatic brain injuries victims should be paid and that the at-fault party must be held accountable.

Client-Attorney Relationship – During a traumatic brain injury case, the relationship between an attorney and the client is a lot like any other lawyer-client interaction. It’s important for the agent and client to get along well so they can talk openly about how the client is doing as he or she gets better. The lawyer and the client should often talk about the injured person’s care, such as the names of the doctors who are helping them. The lawyer must also give the wounded person a chance to ask any questions he or she may have.

A TBI Lawyer’s Responsibilities – A lawyer’s other job is to gather important medical information about the wounded person’s care. The personal injury lawyer not only gathers this information, but also reads it, evaluates it, and, if necessary, talks to the doctor about medical paperwork. In the same way, the Traumatic Brain Injury lawyer talks to both the insurance company of the person who caused the accident and the insurance company of the person who was hurt with the aim to manage the claim as quickly and efficiently as possible. This is done to make sure that the person who was hurt gets the most money possible based on the circumstances and facts of their claim.

The Way Of A Criminal: Chapter 4

Genre: Mafia!AU, Criminal!AU, Angst, Romance

Pairing: OT7 x Reader

Characters: Normal!Reader, Gangster!Namjoon, Gangster!Seokjin, Gangster!Yoongi, Gangster!Hoseok, Gangster!Jimin, Gangster!Taehyung, Gangster!Jungkook

Summary: Your father was a stranger, you never knew who he was and what he did. But one day, someone knocks on your door, informing you of his passing. Now, you learn more about him, his life and the legacy you are expected to continue with the help of his 7 executives.

Story warning(s): This story will contain depictions of violence, blood shed/gore, death, mentions of abuse, smoking, alcohol drinking and gambling. This story is fictional and has nothing to do with real life events or the actual members of BTS. Please read at your own discretion.

Instead of dealing with all this head on, you avoided it. You put everything aside and went on with life, spending all your time doing work, studying and doing your university projects.

Wonwoo noticed this and decided to invite you for a night out. Just a chill night with some drinks. Usually, you would decline, which is why Wonwoo has never invited you out. But you could use the distraction. Maybe being out of the house was good.

DING DONG

“Coming!” You ran down, fixing your earring. You didn’t really know how to dress for a night out like this so you picked a random dress. It was a dark blue, crushed velvet cocktail dress.

“Come on in.” You opened the door for him. Wonwoo smiled, bowing before removing his shoes to come in.

“This dress isn’t really motorcycle friendly, is it?” You let out an awkward laugh, going into the kitchen to get your phone that you left there to charge.

“I didn’t ride my bike since we might drink. I’ll call a cab.” Wonwoo said. He just stood in the doorway, unsure of what to do since it was the first time he was in your house.

“(y/n)?” Wonwoo suddenly called your name, stopping you in your tracks.

“You look great.” He smiled softly.

“Oh... Thank you.” You felt your cheeks heat up at his sudden compliment. He held out a hand to support you as you wore your shoes. After locking up the house, he escorted you to the cab that was waiting for you. And of course, Wonwoo opened the door for you to get in first, being the gentleman that he is. The car ride was silent.

“C-Can I ask you something?” Wonwoo threaded lightly. You hummed, nodding your head.

“I know you like your privacy and I shouldn’t pry but there were this rumours and pictures floating around about some expensive sports car and handsome guy picking you up. Is he one of them?” He asked nervously.

“If by ‘one of them’, you mean my father’s... employees. Yes, he is... or was. There are 7 of them.” You rubbed the back of your neck.

“Are they bothering you?”

“Can we not talk about this anymore? I just don’t want to have to think about it for a few minutes.” That came out a lot harsher and colder than you expected. But Wonwoo didn’t react.

“Sorry. I’m...” You sighed, not really knowing how to piece your words together anymore.

“I understand. Don’t worry about it. I didn’t mean to pry.” Wonwoo smiled comfortingly. Thankfully for you, the cab stopped outside the club. You looked at the long line outside that didn’t seem to be moving,

“Don’t look so worried. My friend put our name on the list so we can just walk in.” Wonwoo laughed. You both got out and he grasped your hand, giving your names to the bouncer. You were so stunned by his action that you just followed him without a word, letting him lead you.

“There’s a table there.” Wonwoo said in your ear on top of the loud music. You were still shocked that he was holding your hand that you just followed him.

“Phew, it’s crowded.” You said, casually pulling your hand away to check if you dropped anything from your bag.

“Yeah, that’s what you get for being here on a Friday night.” He chuckled. You stood at the table while Wonwoo went to get drinks at the bar. The standing table was thankfully at the side of the bar, which meant less people.

“Relax, you’re here to have fun.” You told yourself.

“Here.” Wonwoo got himself a beer and got you a cocktail. It was a nice refreshing drink with flavoured soju as the alcohol.

“Let me know how much everything is tonight and we’ll split the cost.” You told him as you took a sip.

“It’s okay, (y/n). It’s my treat, just enjoy yourself.” Wonwoo smiled. He clinked his glass with yours. Although this wasn’t your exact idea of relaxing, you were glad that the noise and the crowd made the place too loud that you didn’t need to start sharing your feelings. Wonwoo was a good friend but you just weren’t used to sharing so much about yourself with others.

After some drinks, you excused yourself to go to the toilet. But of course, there was a line. About 15 minutes went by without the line moving. You were about to give up when someone grabbed your wrist.

“(y/n) sshi?” You looked at the familiar face.

“Oh... Uh...”

“Yoongi.” He said, letting you go. You nodded your head. Other people in the line now had their attention on you and Yoongi.

“Come.” He nodded over to follow him. You didn’t know why you just went along, not even asking why he wanted you to go with him. You came before a staircase with two guards. But they parted ways upon seeing Yoongi.

“Sir.” They bowed respectfully as Yoongi cooly walked up, hands tucked into his pockets. You quickly bowed your heads back to the guards and caught up to Yoongi.

“You can use this bathroom instead. It’s cleaner and safer.” Yoongi stopped before a door.

“A-Are you sure?”

“If I wasn’t sure, I wouldn’t have went down to fish you out of the crowd. Take all the time you need. This is our own private bathroom so no one else is allowed to use it.” He explained. You nodded, bowing gratefully to him before entering the restroom.

The bathroom was a lot more opulent and grand, with black granite and gold trims. Like Yoongi said, it was very clean, unlike a usual club bathroom. It was definitely a boys bathroom with urinals but you just used one of the stalls.

“Hyung, why can’t I use the bathroom? I really need to go!” You heard voices outside as you were washing your hands.

“Only the 7 of us use it anyway. Unless... Do you have a secret guest in there?!” The person talking to Yoongi gasped as if he just uncovered something scandalous.

“Watch your mouth.” You heard Yoongi threaten.

“Sorry, I’m done.” You opened the door. But you didn’t expect Yoongi to be standing so close that you ended up bumping into his back.

“Oh, no wonder hyung was guarding the bathroom.” The male said. He didn’t mind you and just brushed past to use the bathroom. Yoongi moved you away from the bathroom door, not wanting you to accidentally get hit.

“Thank you. Is it okay if I just stay here for a few more minutes? You can go back to what you were doing before.” You asked timidly. Yoongi took one look at you and nodded. You didn’t need to tell him anything for him to know what you were thinking. The club was getting overwhelming. Yoongi never really liked coming too unless his brothers make him.

“Why did you come if you don’t like it?”

“A friend brought me here as a distraction. Plus, I’ve never really come to a club before.” You replied. Yoongi nodded his head.

“You don’t need to stay and accompany me. I’ll go back down in a bit.” You said.

“It’s okay.” He leaned against the opposite wall. You took your phone out to send Wonwoo a text, assuring him that you were safe and that he could go home first. But you didn’t tell him where you were and who you were with.

“Actually... I wanted to apologise. My brothers told me I shouldn’t have offered you a smoke the other time. I just thought it would help.” Yoongi looked at you.

“It’s fine. I honestly didn’t think too much about it. There were other things to think about.” You shook your head.

“Understandable. I’m sure you have your fair share of confusion and questions that come along with it. This is just the start.” Yoongi said. You didn’t let his straightforward tone faze you, nodding your head glumly.

“Well, I should go. Thanks for letting me hang here.” You straightened up.

“No worries. I’ll walk you down.” Yoongi followed suit. You walked behind him, not sure of the way to the exit. With your insistence, Wonwoo had gone home on his own. You did feel bad for abandoning him when he was the one that invited you out but you also didn’t want him to wait.

“Do you have a ride home?” Yoongi asked.

“I told my friend to go home first so I guess I can get a cab home.” You waved him off, getting your phone out. But Yoongi stopped you, his hand grasping your phone and covering the screen.

“It’s not safe and cheap to get a cab from here at this time. I drank a little so I shouldn’t drive. Hang on.” Yoongi waved over one of the bouncers.

“Use the company car and send her home then report back.” Yoongi ordered.

“Yoongi sshi, it’s really okay.”

“Get the address from her and make sure you see her entering the house before coming back.” Yoongi ignored you. The bouncer nodded and bowed, running off the get the car.

“(y/n) sshi, hyung.” You both turned to see Taehyung jogging over. He had a big, square-ish grin as he waved.

“Jimin said you were here and that Yoongi hyung was with you. Are you driving her home, hyung?” Taehyung tilted his head.

“I drank. So was gonna get one of the workers to drive her back.” Yoongi explained, standing back as he lit a cigarette to smoke. Taehyung nodded his head.

“I’ll drive you home. I didn’t drink since I am the designated driver tonight. Bring my car instead.” Taehyung called out. The worker bowed and ran back into the club. Yoongi decided to go in first after his cigarette was done, not liking being out in the cold. He shot you a nod while you bowed gratefully to him. While waiting, Taehyung put his jacket over your shoulders.

“Did you come alone?” Taehyung asked.

“No... I came with a friend but I abandoned him. Yoongi sshi was kind enough to let me hang out in the quiet area. So I told my friend to go home first.” You said. You didn’t know why you were explaining so much to him.

“This isn’t you scene, is it?” He teased. You pursed your lips and shook your head. The noise and the crowd just wasn’t comfortable.

“Sir.” The car stopped right in front of you. The worker came out, bowing and passing Taehyung’s keys to him.

“Here you go. Watch your head.” Taehyung opened the car door for you to enter. You sat inside, keeping the sides of his jacket close to you so it wouldn’t get caught in the door.

Taehyung confirmed your address before starting to drive. One hand held his head, elbow resting on the door next to him while the other hand was on the steering wheel. During the quiet ride, you fiddled with the hem of the dress, pulling it down every now and then.

“Are you cold?” He asked.

“No, I’m good. Thank you.” You replied softly. With your head leaning against the headrest, you looked out the window. The only reason you would be out this late usually was because you were working.

“Thanks for dropping me off again.” You said as Taehyung pulled up outside of your house.

“Any time.” Taehyung smiled. You unbluckled your seatbelt and got out of the car. But before you could walk further, Taehyung rolled down the window.

“Goodnight, (y/n)!”

“G-Goodnight, Taehyung sshi.” A small smile formed on your lips as you bowed your head and entered the house. Like the other day, Taehyung only drove off after he was sure you had entered the house.

Only after you entered the house and you heard Taehyung drive off, that you realised you had forgotten the return him his jacket. You removed it carefully, as if any movement would cause it to tear like tissue. You inspected it, trying to figure out if you should wash it on your own, and risk ruining the expensive material, or just send it for dry cleaning.

“Hi, Wonwoo. Did you make it home safe?”

“Oh, (y/n). Yes, I am home. I went home after you sent me that text. Are you alright? You scared me.”

“Yes, I am alright. I just found a quiet space to chill for a while so I didn’t want you to wait for me. I just got home. Sorry for ruining the night. I’ll make it up to you, I promise.” You said, putting your shoes away.

“Don’t say that, (y/n). I’m sorry you didn’t enjoy yourself.”

“I did enjoy myself, Wonwoo. Thank you for bringing me out to feel better.” You laughed. After wishing each other good night, you hung up.

You took a shower and was feeling peckish so you made yourself some ramyeon. There was always ramyeon in the kitchen for when you or your mother needed a late night snack after working.

“I’ll have to drop the jacket off at the dry cleaners tomorrow.” You groaned tiredly, looking at the blazer that rested over the back of the chair.

Hoseok was one of the first ones to wake up. After a day of working and a night of drinking, the boys all usually slept in during the weekends. The moment his foot touched the bottom of the stairs, a maid ran over to him, bowing her head in fear.

“What is it?” He raised an eyebrow.

“Your workers are here, sir. They said that it is important for you to see them immediately.” She relayed timidly, afraid of making him angry.

“Send them in. And get my breakfast.” Hoseok shooed her away before shuffling to the dining room. Like any other normal person, he didn’t like having to work on the weekends.

“Good morning, Boss.” The 3 men put the crate that they were carrying down and bowed to Hoseok.

“This better be important for you to be here on a Saturday morning.” Hoseok said, not even looking up at them. He was more focused on the tray of food that the butler had placed down in front of him.

“The shipment is here early. We thought you would want to check it right away.” One of the men informed. Hoseok put his napkin on the table and stood up.

“Show me.” He commanded as he walked over. The men opened the box, revealing the contents inside.

“Very nice...” He picked up one of the items.

“Business on a Saturday morning, Hobah?” Yoongi came in. Hoseok’s workers bowed upon seeing the pale man enter the dining room. But of course, he didn’t even spare them a glance. He sat down in his allocated seat, waiting for the staff to serve him his breakfast. His breakfast was usually an iced coffee then his food 20 minutes later.

“Can’t help it, hyung. You want the best, you’ve got to work when others aren’t.” Hoseok laughed while Yoongi snorted at his comment. He placed the items back into the crate.

“Leave this here. I’ll show the others to see what they think. Good work. We’ll discuss the rest on Monday.” Hoseok said.

“Of course, boss. Have a nice weekend.” The 3 bowed, moving the crate to the side of the room before leaving the mansion. Hoseok took his seat across Yoongi.

“So hyung, I heard you had a little moment with the girl.” Hoseok asked.

“What moment?” Yoongi asked back, no emotion on his face as he sipped the last bit of his coffee.

“Jimin said you loyally guarded the door for her as she used our toilet. Even stayed with her in the hallway after to comfort her.” He explained. Yoongi rolled his eyes, his brothers really needed better things to talk about.

“I saw her the moment she entered, I’m surprised you guys didn’t considering how high our booth is. She needed to use a toilet and the queue was insane so I offered her to use ours. And I wasn’t comforting her, she needed a quiet place and I stayed with her. That’s all.” Yoongi explained.

“Well, that’s a lot more interaction than what the rest have got. Looks like she’ll warm up to you first.” Hoseok said.

“No, she’ll warm up to Taehyung first. He was the one that sent her home.” Yoongi dug into his food on the tray that the butler brought him. Hoseok hummed but couldn’t help the giggle that escaped him.

“What’s Hobi laughing about?” Namjoon came in. He had been awake for a while, opting to sit in his room to read the newspaper rather than come downstairs right away.

“No idea.” Yoongi replied, putting a chopstick of rice into his mouth.

“Ah, seriously, Hobi. I thought we established that we are not going to bring work into the dining room?” Namjoon tsked at the crate in the room.

“It’s fine, Namjoon ah. I’ll move it after breakfast. The boys needed me to inspect the goods, that’s all. Even risked bothering me on a Saturday to do it.” Hoseok waved the leader off. Namjoon shook his head with a sigh.

“Bring my breakfast.” He ordered as he took his seat at the head of the table. The butler bowed and left.

“I’m done. Going back to sleep.” Yoongi stood up and shuffled out of the room. The weekend was for Yoongi to catch up on sleep, it was normal to not see him for the entirety of the two days because he was just sleeping or resting in bed. Jin and Taehyung were the last ones that had breakfast. Jungkook and Jimin would sleep in until dinner time.

“Here. Take what is yours and leave the rest. I told you I would get things done.” Jin dropped the stack of files on the table. Namjoon, Hoseok and Taehyung shrugged, going through the pile to retrieve their things.

“So, hyung, did you find out anymore information about (y/n) when you did your stalking?” Taehyung asked.

“Yah, Taehyung! That was supposed to be confidential.” Jin hissed at the younger exposing him to the rest. However, the younger just shrugged.

“You’re running a check on her?” Namjoon raised an eyebrow.

“I’m not running a check on her... Well, at least not the background checks I usually do. I just wanted to find out about her to maybe try to connect with her in some way. She is a closed book.” Jin explained.

“So what if she is a closed book, I’m sure you can still find whatever you need on her.” Hosoek laughed.

“That’s the thing... She does not have much of a record except for her birth certificate and basic school details. Everything else either doesn’t exist or has been wiped.” Jin informed.

“Wait, you’re telling me there is actually information that you can’t find?”

“How do you know information has been wiped? She could have just not had that much of an eventful life so far. I doubt she can wipe her own records and she doesn’t seem to have a reason to do that.” Namjoon said. He didn’t know you but you didn’t seem like a skillful hacker that could wipe records.

“I know information has been wiped because I am the one who wiped them...” Jin admitted with his head slightly hung.

“What?”

“Boss wanted me to wipe them. He was paranoid, especially when it came to her. So my task was to regularly wipe her records that were 'not relevant’. Hospital visits, stuff like that...” Jin gulped.

Small amounts of liquorice raise blood pressure - Technology Org

New Post has been published on https://thedigitalinsider.com/small-amounts-of-liquorice-raise-blood-pressure-technology-org/

Small amounts of liquorice raise blood pressure - Technology Org

It is known that large amounts of liquorice cause high blood pressure. A study by researchers at Linköping University now shows that even small amounts of liquorice raise blood pressure. The individuals who react most strongly also show signs of strain on the heart.

A liquorice – illustrative photo. Image credit: Pixabay (Free Pixabay license)

Liquorice is produced from the root of plants of the Glycyrrhiza species and has long been used as a herbal remedy and flavouring. However, it is known that eating liquorice can also raise blood pressure. This is mainly due to a substance called glycyrrhizic acid that affects the body’s fluid balance through effects on an enzyme in the kidney. High blood pressure, in turn, increases the risk of cardiovascular disease.

Both the European Union and the World Health Organization have concluded that 100 mg of glycyrrhizic acid per day is probably safe to eat for most individuals. But some people eat more liquorice than that. The Swedish Food Agency has estimated that 5 per cent of Swedes have an intake higher than this level.

Is the limit safe?

In the current study, published in The American Journal of Clinical Nutrition, researchers at Linköping University wanted to test whether the limit stated as likely safe actually is so or not.

It is not easy to know how much glycyrrhizic acid is in the liquorice you eat, as its concentration in different liquorice products varies greatly. This variation may depend on factors such as origin, storage conditions and liquorice root species. In addition, the amount of glycyrrhizic acid is not indicated on many products. The Linköping University study is the first to have carefully measured the amount of glycyrrhizic acid in the liquorice that was tested, while being randomised and having a control group.

Ate liquorice for two weeks

In the study, 28 women and men aged 18–30 were instructed to eat liquorice, or a control product that did not contain any liquorice, over two periods of time. The control product instead contained salmiak, which gives salty liquorice its flavour. The liquorice weighed 3.3 grammes and contained 100 mg of glycyrrhizic acid, that is, the amount indicated as likely safe for most people to eat daily. Participants were randomly assigned to eat either liquorice or the control product for two weeks, take a break for two weeks, and then eat the other variety for two weeks. This enabled the researchers to compare the effect of both varieties in the same person. The study participants were asked to measure their blood pressure at home every day. At the end of each intake period, the researchers measured levels of various hormones, salt balance, and heart workload.

“In the study, we found that a daily intake of liquorice containing 100 mg glycyrrhizic acid raised blood pressure in young healthy people. This hasn’t previously been shown for such small amounts of liquorice,” says Peder af Geijerstam, doctoral student at the Department of Health, Medicine and Caring Sciences at Linköping University, general practitioner, and lead author of the study.

When the participants ate liquorice, their blood pressure increased by an average of 3.1 mmHg.

Some were more sensitive

The researchers also measured two hormones that are affected by liquorice and that regulate fluid balance: renin and aldosterone. The levels of both of these decreased when eating liquorice. The quarter of the study participants who were most sensitive, based on their levels of the hormones renin and aldosterone decreasing the most after eating liquorice, also gained slightly in weight, most likely due to an increased amount of fluid in the body. This group also had elevated levels of a protein that the heart secretes more of when it needs to work harder to pump around the blood in the body, N-terminal pro-brain natriuretic peptide (NT-proBNP). This suggests increased fluid volume and heart workload in the individuals most sensitive to the effects of liquorice.

“Our results give reason to be more cautious when it comes to recommendations and labelling for food containing liquorice,” says Fredrik Nyström, professor at the same department, who was responsible for the study.

The study was funded with support from, among others, The Strategic Research Network in Circulation and Metabolism (LiU-CircM) at Linköping University, The National Research School in General Practice at Umeå University, King Gustaf V and Queen Victoria Freemason Foundation and Region Östergötland.
