BUY CIALIS NO PRESCRIPTION, It is beyond cliché to say that most New Year’s resolutions are forgotten by the second week of January. Similarly, CIALIS interactions, I’ve noticed that spring cleaning rarely has the impact it was intended to have.

The best time to work on self-improvement is during the summer – when the days are longer, the weather is warmer, online buying CIALIS, and people feel altogether happier and sharper. CIALIS wiki, If you are looking to improve your professional skills this summer, few things will help you as much as picking up some basic computer programming experience. Learn- ing how computer programs are used to automate tasks and how you can manipulate them to work for you will improve your efficiency at work, buy CIALIS from mexico, give you a sense of satisfaction, CIALIS from mexico, and empower you to focus more on the creative and intellectually stimulating parts of your work. I’m not suggesting that you start by creating your own applications, but instead that you acquaint yourself with the more advanced tools that are available in the applications you already use, BUY CIALIS NO PRESCRIPTION.

Build on what you already know

If you spend most of your time working in Excel, pick a few keyboard shortcuts from the menus and make a concerted effort to use them regularly, CIALIS steet value. If you find yourself doing a repetitive task, CIALIS brand name, spend a few minutes searching online to see if there’s a faster way. You can create some very simple keyboard macros, then look at the Visual Basic scripts behind them and tweak the scripts to do more tasks or do tasks better, is CIALIS safe.

To help you improve your Excel skills, Low dose CIALIS, ChEnected features a series of tips called Excelling with Excel. More-advanced training is available with the AIChE eLearning short course, “Spreadsheet Problem-Solving for ChemEs."

BUY CIALIS NO PRESCRIPTION, There are plenty of free tutorials online that will walk you through creating joins graphically and that will empower you to work with larger datasets more efficiently.

If you are working in engineering-specific software like Aspen, look into the alternative view modes for a textual explanation of the diagrams in front of you, CIALIS alternatives. Although the visual representation of a process is easier to understand at a glance, Herbal CIALIS, understanding the underlying code that represents the diagram will unlock additional features and improve your workflow. Like the character Cypher in The Matrix tells us, “You get used to it, CIALIS from canadian pharmacy. I don’t even see the code. All I see is _____.” Fill in the blank: pump, mixer, heat exchanger, etc, BUY CIALIS NO PRESCRIPTION. Online buying CIALIS hcl, Readers seeking a refresher on the fundamentals of HTML coding can learn for free with the interactive exercises presented at the site

The move from text to visualizations

With improved technologies that enable instantaneous and archived video transmission, much of the work we do is moving toward graphical representations and textual shorthand that would be incomprehensible to Shakespeare, purchase CIALIS, Chaucer, CIALIS dose, or even Orwell. Although I hope that students never stop learning proper, written English, effects of CIALIS, I suspect that writing five-page essays will become less important in the near future. Buy CIALIS no prescription, Students will instead pick up elementary programming, starting with graphical instructions sets (I recommend the open-source program Alice, which is aimed at elementary school students) and continuing into high-level object-oriented languages, buying CIALIS online over the counter. BUY CIALIS NO PRESCRIPTION, Being able to not only use a computer, but also instruct it to do something new, transforms the casual user into a creator and can provide unparalleled satisfaction for the novice programmer. Although we are not manipulating actual machinery the way our parents may have in college, Rx free CIALIS, we have the ability to do much more with much less. Basic computer programming opens up not only the ability to automate tasks, but also enables the creation of movies, CIALIS treatment, music, CIALIS gel, ointment, cream, pill, spray, continuous-release, extended-release, and games, as well as new custom-designed applications.

Using these potential outlets to motivate students to study a fundamentally academic discipline is akin to the chemistry set of the 21st century, get CIALIS, without the risks of fire or mercury poisoning. CIALIS trusted pharmacy reviews,

Job security through new skills

Some of the world’s most innovative and successful people have come together to form, an initiative that aims to raise awareness of the need for computer science education at every level. claims that by 2020 there will be one million more jobs in the U.S, BUY CIALIS NO PRESCRIPTION. that require computer scientists than there will be students graduating with computer degrees to fill those jobs. There will also be many more jobs that can benefit from familiarity with the same skills. Chemical engineering graduates have experience increasing the efficiency of large processes and will be particularly equipped to take on those opportunities.

Steve Jobs famously stated that everybody “should learn how to program a computer because it teaches you how to think.” If any academic discipline forces students to think at the most fundamental level, it is chemical engineering. By combining the lessons of both disciplines, chemical engineers with programming experience are in the best
position to succeed.

What's your summer self-improvement project?

Consider  alternative  offers

When  negotiating  for  a  better offer, you may hear that all engineers of a certain level receive the same salary, order LANOXIN from mexican pharmacy. Such levels may exist, but even if base salary is not negotiable, other parts of your compensation package may be, LANOXIN FOR SALE. You might ask for a signing bonus, Comprar en línea LANOXIN, comprar LANOXIN baratos, or a moving stipend, or a review after six months with a predefined potential for a raise. These are effectively salary increases and may allow the company to maintain its system of  salary  levels  while  still  satisfying  your  request, LANOXIN dose.

What  matters  more  to  you?

Even  if  the  company  cannot offer a larger salary, Rx free LANOXIN, it may be able to provide higher compensation in other  meaningful  ways.

Why should  selling  your  services  be  any  different.  The  worst  that   can  happen  is  the  employer  will  say  no  and  stay  with  the original offer; the employer will not rescind the offer altogether because you asked for higher compensation. LANOXIN FOR SALE, When  you  do  come  to an agreement, however, be gracious and express gratitude that  you  were  able  to  compromise.  That sentiment will  stick with  your  employer.

Regardless of what you negotiate, be sure to follow through as  though  you  were  buying  a  car  or  a  house.  Make sure every part of the offer is in writing, ask that it be signed, and keep a copy for yourself. The company should be  proud  of  the compensation it can offer to you and you should be proud to accept it.

ZOVIRAX FOR SALE, I’ve come to understand that when one person tells another person to do something, the instructions often represent the requester’s most basic expectations. To many people, fulfilling any set of carefully laid out instructions — whether they are from an employer, ZOVIRAX recreational, a friend, ZOVIRAX no rx, a mentor, or a coach — means completing and delivering the bare minimum. Such an effort is worth only a passing grade, what is ZOVIRAX. To surpass the merely adequate, Buy ZOVIRAX without a prescription, and to accomplish something noteworthy, requires one to take on tasks that are unstated and to solve problems that others may not have even noticed.

Volunteering while on the job

Depending on the structure of your work environment, buy ZOVIRAX online cod, there may be opportunities to do this professionally. At a small company like AIChE, where I work, the staff often has more projects to pursue than there is time to complete them, ZOVIRAX FOR SALE. Online buy ZOVIRAX without a prescription, A situation like this can give young employees a chance to demonstrate their versatility and competence by helping with projects that might not be in their job descriptions, but that allow them to pursue their interests and demonstrate their ability to accomplish the organization’s goals.

For a young professional, ZOVIRAX from canadian pharmacy, taking on a new role or contributing skills outside of one’s defined job description provides an opportunity to excel in the workplace without having attained the technical expertise of more-experienced coworkers. For example, today’s young engineers — who have never known a time when high-power personal computing was not a fully integrated part of their lives — can play to this strength on the job, buy cheap ZOVIRAX, expertly demonstrating to more-seasoned but less-computer-savvy engineers how to accomplish a variety of tasks more efficiently. Online buying ZOVIRAX,

Leadership opportunities

Even outside the office, there are many opportunities to contribute to the engineering community — and carve a niche for oneself — through leadership roles. ZOVIRAX FOR SALE, Young professionals with experience in all fields can get involved in the leadership of AIChE’s volunteer activity groups, including local sections and young professionals groups, technical divisions and forums, and Institute-level committees devoted to a variety of projects that serve chemical engineers and the profession at large.

Patrick Gormley, ZOVIRAX australia, uk, us, usa, chair of the Maryland Local Section, ZOVIRAX wiki, encourages chemical engineers in his community to expand their experiences and connections by joining the local section, attending the events it sponsors, and trying everything that sections have to offer — including K–12 and public outreach activities, buy ZOVIRAX no prescription, plant tours, ZOVIRAX steet value, monthly technical talks, and interaction with chemical engineering students.

AIChE leadership workshop

AIChE supports the essential work of its local section volunteer leaders through annual training workshops that give member volunteers a better understanding of AIChE’s mission and objectives, where to buy ZOVIRAX, and help to build a strong connection between the Institute and its grassroots representatives on the local and regional levels. ZOVIRAX cost, The next such opportunity for this connection is the 2013 AIChE Local Sections’ Leadership Workshop (LSLW), to be held April 27–28 in San Antonio, TX, ZOVIRAX without a prescription, in conjunction with the 2013 Spring Meeting and Global Congress on Process Safety. Travel grants for the LSLW are offered to local sections with less than $15, ZOVIRAX pharmacy, 000 in reserves or to potential leaders (including AIChE young professionals) who are interested in starting or re-energizing a local section. You can register and find grant information here, ZOVIRAX FOR SALE.

Gormley attended the 2012 Local Sections’ Leadership Workshop, in Houston, ZOVIRAX online cod, TX, Generic ZOVIRAX, where he says he learned to think about how his section can impact the lives of the engineers in his community. He noted that the LSLW “was a great place to hear about what other local section leaders are doing,” and that every section leader “faces the same issues, herbal ZOVIRAX, namely, ZOVIRAX dangers, how do we maintain relevance in our members’ lives?”

Gormley says that he was particularly inspired by the young professional leaders he met. He has taken some of their nontraditional programming suggestions back to his section, where he has created more social-educational activities, purchase ZOVIRAX for sale, such as a beer tasting event coupled with a viewing of the AIChE webinar about beer brewing. (The webinar is available to members here.) Gormley encourages other leaders to “inspire the habit of attending local section meetings in members before they get older and their lives become busier.”

Outreach to students

Many young professionals also find that they can make a meaningful contribution to their communities through volunteer service.

ZOVIRAX FOR SALE, Jason Huang, an AIChE member from Houston, TX, makes presentations at his neighborhood high school’s National Honor Society about the path that led him to study and practice chemical engineering. (You can read about Jason's outreach work here.) Other AIChE members are creating high school outreach programs based on their work in solids processing and reaction engineering.

Regardless of your specific interests, there are many opportunities to take on leadership roles in AIChE. And, if you find that you are not passionate about one volunteer activity, there are always plenty more to choose from.

Gormley says that his local section members are “leaders in industry, working to make their community more successful. Working with them to improve that community is gratifying in itself.”

When it comes to taking on a new leadership function — within or outside of work — inaction is the only choice that is truly regrettable.

How has volunteering made a difference in your career or life?

VIAGRA FOR SALE, John Vasko, associate director of community and content for AIChE and ChEnected, and Arjun Gopalratnam, Young Professional and International Program lead, interviewed Sarah Ewing about moving from school to the business world on a video chat. Sarah graduated from UC Irvine 2010 with a B.S. in Chemical Engineering. Buy cheap VIAGRA, She worked as a field engineer at Schlumberger and now serves as a field applications engineer at FMC.

You can check out the full video interview in the panel to the right or read the transcript below.

Please ask Sarah your own career questions below in the comments area!

Our Interview with Sarah Ewing

Arjun: Where did you go

to college and how did you decide to study chemical engineering?

Sarah: I attended University of California, Irvine, and graduated in June 2010 with a degree in chemical engineering.  I chose chemical engineering as my degree because I liked chemistry in high school and I wanted to be an engineer for the job stability, VIAGRA FOR SALE.

A: After graduating in 2010 you moved to Oklahoma. How did you decide to do that?

S: When I was looking for jobs after college, buy VIAGRA from mexico, I was offered a position as a field engineer at Schlumberger, and the district I was assigned was in Oklahoma City, Purchase VIAGRA online, OK.   I actually did want to move to another state, just because I have always been a big traveler and I can appreciate almost any city.  Schlumberger also paid for relocation so that was a big plus.

A: Did you have unusual hours at Schlumberger?

S: Oh yeah. Working for Schlumberger was definitely an awesome experience overall, VIAGRA coupon, however it is definitely not for everyone. VIAGRA FOR SALE, I have always been very hard working, and I like keeping busy, so working ridiculously long hours was doable for me at the time (though not always enjoyable). However, Purchase VIAGRA online no prescription, there were some great benefits, including a good paycheck, absolutely amazing people, and lots of responsibility early on, what is VIAGRA. My supervisor experience looks fantastic on my resume and I always get asked about it first thing in interviews.

A: And what do you do now?

S: Currently I still am working in the field, Cheap VIAGRA, but I changed companies to an industrial chemicals company called FMC.  I actually do not work in the plant, I work in our technical services department, so we actually do a lot of traveling out to customer sites who actually purchase our chemicals and we will design and set up the application delivery system (usually a pumping system which ties into the water lines). So far I have gotten to go to poultry plants, VIAGRA dose, a coal power plant, and a few other chemical manufacturing sites. We also do work for wastewater plants, VIAGRA FOR SALE. VIAGRA used for, A: Especially at this time of year, you must be happy to get out of Buffalo a little.

S: Oh yeah. This is my first winter with snow. It has been interesting to say the least, VIAGRA australia, uk, us, usa, but so far I am making it through and staying positive.

A: You went from Southern California to Oklahoma to Buffalo, Online buying VIAGRA, did you get any good advice to help with that transition?

S: I have always been very open to new experiences and places, like I said I love to travel to different cities. VIAGRA FOR SALE, I can appreciate both country areas as well as big cities, and they both have their perks. The best advice I could give is to not shy away from new experiences that scare you, especially in the early part of your career.  For me being a field engineer has given me so much practical experience and opened a lot of doors for me; however, VIAGRA canada, mexico, india, I feel if I would have waited and not done it immediately after graduation, I probably would not go back and do it.  Especially if you think you want to start a family later on; it is probably the best time to do it right out of college. Cheap VIAGRA no rx, Probably the biggest challenge/change I have had in the transition from college to industry is learning to work with different people.  In college, my study group were all engineers and we were all 21 and good friends, however in the working world, it is not always like that, VIAGRA images. I work directly with all age groups, engineers, Buy no prescription VIAGRA online, non engineers and customers.  For this reason, good interpersonal skills are important.

A: We’ve heard that you have approached other students to help them with this transition. How did you get involved with that program?

S: I was president of my AIChE student chapter in college, and I wanted to remain involved now that I am a young professional, VIAGRA FOR SALE. Unfortunately, buy VIAGRA no prescription, both cities I have lived in so far have not had active Professional chapters, so I figured the best way to remain involved was through student chapters. Where can i cheapest VIAGRA online, I remembered when I was in college, I was always trying to get speakers to come to our meetings and give advice, and sometimes it was like pulling teeth to get volunteers. I reached out to local chapters and they were very grateful that I came and spoke with them, where can i buy VIAGRA online. Most recently I did this at University of Buffalo and it was incredibly successful. VIAGRA FOR SALE, I even have had students follow up with me to get career advice. I don't mind helping because it's refreshing to see young professionals being outgoing about their careers. VIAGRA alternatives, A: Are there any benefits that AIChE has provided to help you in your career or as a student?

S: Personally my favorite part of AIChE is just the networking and meeting other chemical engineers across the country.  My favorite part of AIChE in college was the conferences hands down. My college had a pretty small chemical engineering class, and most of them were commuters so I didn’t interact with them much. At the conferences I always made friends who understood all of the obstacles chemical engineers face, VIAGRA from canadian pharmacy, and I still keep in touch with a lot of them today. As a young professional in a new city, AIChE has also connected me with new friends, VIAGRA FOR SALE.

A: Would you recommend other students follow a path like the one you took?

S: If I had to do it all over again, Kjøpe VIAGRA på nett, köpa VIAGRA online, I would do it exactly the same.  I think putting myself outside of my comfort zone and taking on rather demanding field positions has benefitted me immensely. I have also met a lot of absolutely amazing friends that I would not have met otherwise. Again, I think after college is the perfect time, VIAGRA interactions, because if you work for 10 years in an office position and start a family, you will probably not want to go out in the field and work on an on-call schedule like I did.  However, VIAGRA from mexico, I think my field experience in the most valuable skill on my resume.

A: Would you recommend other students to leave the area that they are coming from?

S: It all depends. VIAGRA FOR SALE, I actually was the weird one after college because no one could understand why I would ever want to leave the great state of California. But like I said, I like to travel and visit new places, where can i find VIAGRA online. I actually lived in downtown Oklahoma City which was a pretty nice place; I was about 5 miles from the Thunder Stadium, for example.  When I lived there my friends and I traveled to Chicago, Order VIAGRA from mexican pharmacy, Dallas, Houston, and Austin for weekend trips.  Now in Buffalo, I have already been to New York City about 3 times, and I have also been to Toronto, Baltimore and Philadelphia, so I have gotten the opportunity to go to lots of different places which would have been harder (and more expensive) if I was still living in California.  However, I understand that it is not for everyone. Some people have tight knit families or children and they cannot just pick up and leave like I did.

A: What’s next for you – grad school?

S: I have toyed with the idea of getting my MBA, but no definite plans yet. I have thought about maybe transitioning my career towards a sales and business direction, since I like to deal with people and the business side of things; however, that could change a few years from now also, VIAGRA FOR SALE. I still am deciding myself.

A: Any other advice for our viewers from ChEnected, both students and young professionals around the world.

S: The best advice I can give to a young professional starting out in their career is to always show initiative at work; however, do not be intimidated and afraid to ask questions either.  Wasting hours trying to figure something out which could be answered in 10 seconds by asking a question is not practical; however, always do your own research first and show that you made the effort to solve the problem yourself. Finding the balance between showing initiative and asking for help is key in the early stages of your career.

A: Thanks a lot Sarah, John, and our ChEnected audience.

S: Thanks for having me.

If you're a professional interested in participating in a Google Hangout about your career, e-mail your idea to

DNA BUY LEUKERAN NO PRESCRIPTION, The ubiquity of digital and server-stored file formats has brought about increased interest in ensuring that creative works conceived today will be preserved, digitally, forever. Chemical engineers play an important role in preserving this information, LEUKERAN description, and new research suggests that bioengineers may also be able to contribute.

Modern today, forgotten tomorrow

Some of today’s best television shows are filmed and edited digitally and then released solely online, is LEUKERAN addictive, through content providers like Hulu, Buy cheap LEUKERAN no rx, Netflix, or YouTube. Although this can provide a convenient viewing experience, LEUKERAN price, coupon, some important factors must be considered pertaining to the long-term viability of such art. Generic LEUKERAN, Those companies will certainly not be around forever. I would like to think that future generations will be able to have access to today’s video, art, and music  to help them decipher what life in 2012 was like, the way that contemporary historians can extract information from cave drawings that depict life 50,000 years ago, or become mesmerized by celluloid film images from 100 years ago, BUY LEUKERAN NO PRESCRIPTION.

Modern data storage excels at many things: ease of transport, random access, LEUKERAN used for, and incredible economies of scale among them. LEUKERAN maximum dosage, At the same time, it is susceptible to temporary loss in the event of power outages and natural disasters, and permanent loss due to changing Internet legislation or cyber terrorism — not to mention the ever-evolving software and technology used to encode and access the data, where can i order LEUKERAN without prescription. Digital media created and “saved” using the standard software of only a decade ago may no longer be easily readable using today’s devices and standard platforms. LEUKERAN duration,

Storage through nature itself

If we were to design a storage format with the goal of having the data last forever, it might help to borrow from a model that has proven itself to be nature’s long-lasting data-storage format — DNA. BUY LEUKERAN NO PRESCRIPTION, DNA and RNA are remarkably simple considering their universality (they are found in all living things) and how accurately they transmit encoded data. They can store data for an incredibly long time (under the right conditions, cheap LEUKERAN, an upper limit is estimated to be one million years) and their position at the very center of biology means that the format is unlikely to ever go out of use. Herbal LEUKERAN, Hard driveThe viability of using a man-made analog to DNA for long-term data storage was detailed in a paper published in the August 17, 2012, LEUKERAN images, issue of Science. LEUKERAN results, Researchers at Harvard Medical School encoded a book with more than 50,000 words into a DNA microchip — a sort of virtual DNA. The researchers converted each character of text into binary code, buy LEUKERAN from canada, the same way a computer would, Buy LEUKERAN from mexico, and then encoded each 1 as a molecule of adenine or cytosine and each 0 as a molecule of thymine or guanine. The end product is a long chain of DNA with each molecule indicating a 1or 0 in the binary code that represents the original text, BUY LEUKERAN NO PRESCRIPTION. The researchers then used next-generation DNA sequencing to read the book.

Although the researchers could have used a base-4 system instead of base-2, where can i buy LEUKERAN online, with each type of nucleotide base indicating a different component of the encoded message, LEUKERAN schedule, the base-2 system avoids problems with reading and writing certain sequences of DNA (e.g., long repeats of guanine andcytosine) that are fragile in nature. Even with this slightly less-efficient encoding, LEUKERAN online cod, the researchers wereable to store 5.5 petabits (that’s 700, Buy no prescription LEUKERAN online, 000 gigabytes) per cubic millimeter of DNA.

Unparalleled efficiency for future storage

At this efficiency, the researchers say, LEUKERAN treatment, about four grams of DNA could store the digital data humankind creates in a single year. BUY LEUKERAN NO PRESCRIPTION, The storage density exceeds any other known method by many orders of magnitude, but there are considerable limitations that will prevent DNA storage from appearing in your next computer. Kjøpe LEUKERAN på nett, köpa LEUKERAN online, For example, the data cannot be read out of order; there will be limited starting points, just as biological DNA has start and stop codons, get LEUKERAN.
