Wi-Fi Underwater

Have you ever imagined using a Wifi underwater?  Well this has been made a reality by a Swedish Defence Research Agency. They have deployed an underwater wireless system to predict weather conditions, volcanoes and earthquakes. This technology is economical, advanced and transmit data at a much higher rate as compared to the traditional echo technology.

Since sensors require cabling underwater which is expensive, this wireless technology provides the best option. Acoustic waves can be used to transmit data underwater similar to the Wi-Fi in the air, more lower the frequency of acoustic waves the more distance they travel. Another research is being carried out by Dr Rosa Zheng at University of Missouri-Columbia regarding the wireless transmission underwater and she plans to make use of MIMO technology facilitating higher transmission. She says:
“MIMO technology provides some challenges because you’re sending a signal at the same time, using the same frequency band, theory proves that it’s feasible, but we’re still trying to figure out how you separate those signals at the receiver.”
The challenge is to overcome the distortions underwater like the bouncing of waves by the surface, unwanted echo and constant surging of sound waves. Geoffrey Edelmann and his team from U.S. Naval Research Laboratory have developed a system to predict the acoustics underwater and plan to add enhancements to it.
With this rapid development in wireless technology, the day is not far when you can access internet underwater.

7 Reasons Why Crying Is Good for You

New York Times reporter Benedict Carey referred to tears in a recent piece as “emotional perspiration.” Given that I sweat a lot and hate deodorant, I suppose it makes sense that I weep often. But I’m not going to apologize for that, because after a good cry, I always feel cleansed, like my heart and mind just rubbed each other’s backs in a warm bath.
In his intriguing article, “The Miracle of Tears” (answersingenesis.com), in which I found some of the research for this gallery, author Jerry Bergman writes: “Tears are just one of many miracles which work so well that we taken them for granted every day.”

Here, then, are seven ways tears and the phenomenon we call “crying” heal us physiologically, psychologically, and spiritually.

1. Tears Help Us See
The most basic function of tears is that they enable us to see. Literally. Tears not only lubricate our eyeballs and eyelids, they also prevent dehydration of our various mucous membranes. No lubrication, no eyesight. Writes Jerry Bergman: “Without tears, life would be drastically different for humans—in the short run enormously uncomfortable, and in the long run eyesight would be blocked out altogether.”

2. Tears Kill Bacteria
No need for Clorox wipes. We’ve got tears! Our own antibacterial and antiviral agent working for us, fighting off all the germs we pick up on community computers, shopping carts, public sinks, and all those places the nasty little guys make their homes and procreate.

Tears contain lysozyme, a fluid that the germ-a-phobe dreams about in her sleep, because it can kill 90 to 95 percent of all bacteria in just five to ten minutes! This translates, I’m guessing, to three months’ worth of colds and stomach viruses.

3. Tears Remove Toxins
Biochemist William Frey, who has been researching tears for as long as I’ve been searching for sanity, found in one study that emotional tears—those formed in distress or grief—contained more toxic byproducts than tears of irritation (think onion peeling). Are tears toxic then?

No! They actually remove toxins from our body that build up courtesy of stress. They are like a natural therapy or massage session, but they cost a lot less!

4. Crying Can Elevate Mood
Do you know what your manganese level is? Neither do I. But chances are that you will feel better if it’s lower because overexposure to manganese can cause bad stuff: anxiety, nervousness, irritability, fatigue, aggression, emotional disturbance, and the rest of the feelings that live inside my head rent-free.

The act of crying can actually lower a person’s manganese level. And just like with the toxins I mentioned in my last point, emotional tears contain 24 percent higher albumin protein concentration—responsible for transporting small (toxic) molecules--than irritation tears.

5. Crying Lowers Stress
Tears really are like perspiration, in that exercising and crying both relieve stress. In his article, Bergman explains that tears remove some of the chemicals built up in the body from stress, like the endorphins leucine-enkaphalin and prolactin. The opposite is true too. Bergman writes, “Suppressing tears increases stress levels, and contributes to diseases aggravated by stress, such as high blood pressure, heart problems, and peptic ulcers.

6. Tears Build Community
In her Science Digest article, writer Ashley Montagu argued that crying not only contributes to good health, but it also builds community. I know what you’re thinking: “Well, yeah, but not the right kind of community. I mean, I might ask the woman bawling her eyes out behind me in church what’s wrong or if I can help her, but I’m certainly not going to invite her to dinner.”

I beg to differ. As a prolific crier, I always come away astounded by the resounding support of people I know, and the level of intimacy exchanged among them. Read for yourselves some of the comments on both my self-esteem file video my death and dying video and you’ll appreciate my point. Tears help communication and foster community.

7. Tears Release Feelings
Even if you haven’t just been through something traumatic or are severely depressed, the average Joe goes through his day accumulating little conflicts and resentments. Sometimes they gather inside the limbic system of the brain and in certain corners of the heart. Crying is cathartic. It lets the devils out before they wreak all kind of havoc with the nervous and cardiovascular systems. As John Bradshaw writes in his bestseller Home Coming, “All these feelings need to be felt. We need to stomp and storm; to sob and cry; to perspire and tremble.”

10 Killer Job Interview questions and Answers

10 Killer Job Interview questions and Answers

Behind every interview question there is a concern or another question. Your job is to process the question thinking about what the interviewer’s concern might be. In other words, why is the interviewer asking you this question?

Q#1 - How long have you been looking for a job? (Concern –is there something wrong with you that other employers have picked up?)

A#1 - “After I was laid off from my last job, I took the opportunity to take some time out to examine my career goals and where I was going with my life. I have just begun my search in the last few weeks. I have a definite goal in mind and have been selective about the positions I consider. Your company and this position are of great interest to me.”

Q#2 - How did you prepare for this interview? (Concern – are you interested enough to do some research, or are you going to “wing it”?)

A#2 - “When I found this position posted on the internet (monster.com) I was immediately interested. I checked out the company website and mission statement, looked at the bios of company founders and executives, and was impressed. Once I had the interview appointment, I talked with friends and acquaintances in the industry. And, I’m sure I’ll find out a lot more in today’s meetings.”

Q#3 - What is your salary expectation for this job? (Concern – Can we afford you? Can we get you for less than budgeted?)

A#3 - “I’ll need more information about the job and the responsibilities involved before we can begin to discuss salary. Can you give me an idea of the range budgeted for this position?”

Q#4 - How do you keep current and informed about your job and the industries that you have worked in? (Concern – Once you get the job do you continue to learn and grow – stay challenged and motivated?)

A#4 - “I pride myself on my ability to stay on top of what is happening in my industry. I do a lot of reading – the business section of the newspapers and magazines. I belong to a couple of professional organizations and network with colleagues at the meetings. I take classes and seminars whenever they are of interest, or offer new information or technology.”

Q#5 - Tell me about a time when you had to plan and coordinate a project from start to finish. (Concern – behavioral questions – seeking an example of specific past behavior)

A#5 - ” I headed up a project which involved customer service personnel and technicians. I organized a meeting to get everyone together to brainstorm and get his or her input. From this meeting I drew up a plan, taking the best of the ideas. I organized teams, balancing the mixture of technical and non-technical people. We had a deadline to meet, so I did periodic checks with the teams. After three weeks, we were exceeding expectations, and were able to begin implementation of the plan. It was a great team effort, and a big success. I was commended by management for my leadership, but I was most proud of the team spirit and cooperation which it took to pull it off.”

Q#6 - What kinds of people do you have difficulties working with? (Concern – ability to be flexible and work in a diverse environment?)

A#6 - “In my last three jobs I have worked with men and women from very diverse backgrounds and cultures. The only time I had difficulty was with people who were dishonest about work issues. I worked with one woman who was taking credit for work that her team accomplished. I had an opportunity to talk with her one day and explained how she
was affecting the morale. She became very upset that others saw her that way, and said she was unaware of her behavior or the reactions of others. Her behavior changed after our talk. What I learned from that experience is that sometimes what we perceive about others is not always the case if we check it out.”

Q#7 - We expect managers to work more than 8 hours a day. Do you have a problem with that? (Concern – are you a work-aholic or a person who requires balance?)

A#7 - “I have no problem working long hours. I have worked 12 or 14 hour days. What I have found works for me is to work smarter, not necessarily longer. My goal is to get the job done, whatever that takes, in the most efficient manner.”

Q#8 - When have you been most satisfied in your career?(Concern – what motivates you? Or demotivates you?)

A#8 - “The job before the one I am currently at, was my most rewarding experience for me. I worked in a wonderful team environment. There was a lot of camaraderie. I worked with a team of four people and we did some really original thinking. It is that kind of environment I want to be involved in again.”

Q#9 - Why do you want this job? (Concern – are you using the shot-gun approach to job search or do you really know what you want?)

A#9 – “I’ve been very careful about the companies where I have applied. When I saw the ad for this position, I knew I found what I was looking for. What I can bring to this job is my seven years of experience, and knowledge of the industry, plus my ability to communicate and build customer relationships. That, along with my flexibility and organizational skills, makes me a perfect match for this position. I see some challenges ahead of me here, and that’s what I thrive on. I have what you need, and you have what I want.”

Q#10 - We are ready to make an offer. Are you ready to accept today? (Concern – we don’t want you to go away and think about it and change your mind – we want you.)

A#10 - “Based on my research and the information I have gathered during the interview process, I feel I am in a position to consider an offer. I do, however, have a personal policy that I give myself at least 24 hours to make major life decisions. I could let you know by tomorrow.”
