Months ago I wrote an article about the importance of having a Mobile Office that you can keep in your car or truck to keep the essential tools you need to run your business close at hand. YOu never know when the opportunity for business may arise ? standing in line at the store, picking your kids up from school, picking up your pets from the vet (my latest opportunity went down right in the waiting room of my Vet?s office!) and with my Mobile Office just a few steps away in my car, I was able to easily make the sale.
Yesterday while I was out shopping for ?Back to School? stuff for the girls, I saw these were on sale ? and at a great price! ? ?So I wanted to make this quick video to show you my Mobile Office and encourage you to get your own set up THIS WEEK while they are on sale! ? Don?t procrastinate ? the sooner you get this done, the sooner your business will benefit!
Never miss another sales opportunity again with a Mobile Office close at hand!

Homeless young women may be at greater risk for sexually transmitted infections (STIs) than homeless young men because of the structure of their social groups and friendships, according to new research from UC San Francisco. The findings underscore how the social networks of homeless youth can be highly influential, affecting their participation in risky and protective behaviors.
The study examined the relationship between STI rates and the characteristics of the social networks of 258 homeless young people ages 15 to 24 in San Francisco. The youth were surveyed about their housing status, risky behaviors and social networks. They also were tested for Chlamydia and gonorrhea.
The researchers found that the homeless young women had lower condom use and a higher likelihood of sex with intravenous drug users than the homeless young men. The women also showed a trend toward higher rates of sexually transmitted infections.
We thought that homeless young women may be at higher risk in part because of whom they had access to in their network, said lead author Annie Valente, MD, who conducted the research while a medical student at UCSF. Social networks are proving to be a very important indicator for other health outcomes, including obesity and cigarette smoking.
Study participants were homeless for two nights or more during the previous six months. Each participant took a computer-based survey, and created a table reflecting their social networks from the previous three months. They listed people to whom they felt close, sex partners, injection partners, and people with whom they had shared resources.
The study, which will be published in the Journal of Adolescent Healthand is now online, also found:
homeless young men were more likely than their female counterparts to have contacts with stable housing and same-sex friends.
when young men had stably housed contacts in their network, they were more likely to use condoms.
female participants were more likely to use condoms when they were able to name a friend of the same gender.
The presence of same-sex friendships and contacts living in stable homes seems to increase condom use, said senior author Colette Auerswald, MD, a UCSF associate adjunct professor of pediatrics and director of the Masters in Medical Science program for the UC Berkeley-UCSF Joint Medical Program. She was based at the UCSF Division of Adolescent Medicine of the UCSF Benioff Childrens Hospital at the time of the study. Young homeless men seem to name these social network contacts more frequently than do young homeless women. It will be important in future investigations to ask why this happens.
The presence of family in the social networks of the young women played an important role in their risk of having sexual partners who are intravenous drug users (IDU). None of the females who listed a family member in their network had an IDU sex partner, whereas 26.4 percent of the women who did not list a family member had an IDU sex partner.
This study shows the importance of reconnecting homeless young men and women to mainstream society, said Valente. It also emphasizes how same-gender friendships and family ties may be effective tools in our efforts to improve the health of homeless youth.
The data collected were part of the Street Youth in Social Environments study, a longitudinal NIH-funded study conducted by Auerswald examining the relationships among street culture, social networks and STI/HIV risk in homeless youth in San Francisco.
This study builds on research that used the same sample of homeless youth in San Francisco to investigate the impact of social networks on shelter use among homeless youth. Published in the June issue of the Journal of Adolescent Health, the researchers found that street youth whose social networks included people who used shelters, increased the odds of their own shelter use over time.
Together these studies suggest the value of designing social network-based interventions to improve the health of our citys marginally housed youth, said Auerswald.

PITTSBURGH (AP) ? Clint Hurdle grabbed the brim of his cap and ducked his head. When pressed about what pleased him the most about Pittsburgh's 9-2 win over St. Louis on Monday, a romp that propelled the resilient Pirates within a half-game of the NL Central lead, the manager thought for a moment and sighed.
"Getting a little picky aren't we?" he asked with a smile.
Hurdle isn't. Neither is his team as it tries to shrug off two decades of misery and mediocrity.
Francisco Liriano allowed one run over seven dominant innings, Pedro Alvarez hit his NL-leading 27th home run and the Pirates kicked off a pivotal series by sending the Cardinals to their season-high fourth straight loss.
Liriano (11-4) continued his midcareer renaissance by striking out eight and walking just two to win his fifth consecutive start.
"It's been a good run for him being able to watch, and that's pretty much what I've been doing," Pittsburgh center fielder Andrew McCutchen said. "I don't get a lot of action when he's on the mound. It makes it a lot easier for the defense."
Having some help from an underachieving offense helps. The Pirates came in hitting just .221 with runners in scoring position, the worst mark in baseball. Clint Barmes smacked two doubles and drove in two runs and McCutchen added two hits as Pittsburgh went 5 for 13 with runners on second or third to continue its mastery over St. Louis starter Jake Westbrook.
The veteran right-hander fell to 1-8 against Pittsburgh in his otherwise solid resume. The Pirates touched Westbrook (7-5) for four runs in the first inning, capped by Alvarez's three-run homer into the first row of seats in right field.
"It was a battle from pitch 1 -- and it showed early on," Westbrook said. "It's not really how you draw it up with a walk and a hit batsmen and a single and a homer. Put us in a bad spot against a good team and against a guy who's throwing the ball really well."
Hurdle stressed the need to not place too much focus on a late-July series, pointing out two more months remain after the five-game set wraps up on Thursday.
Maybe, but with the Pirates chasing their first playoff berth in 21 years and a chance to make inroads on the team with the best record in baseball, the game had an electricity typically reserved for early fall in cities far away from the one that hasn't fielded a winner since 1992.
Lower-lever tickets were fetching $100 or more hours before the first pitch, and Liriano did not disappoint the largest Monday-night crowd (32,084) since the park opened.
The left-hander, whose path to stardom veered off track after undergoing Tommy John surgery in 2007, had little trouble with the most explosive offense in the majors. He retired the first 10 batters he faced and kept the best-hitting team in the National League on its heels while dropping his ERA to 2.16.
"Frankie can answer," Hurdle said. "He's been in big matchups before."
So has Westbrook, who still hasn't figured out a way to handle the Pirates. He was touched for four runs in the first inning of his previous start at PNC Park in April. The game was eventually washed out.
The weather couldn't save him this time. Neither could Westbrook's usually solid control. He issued three walks and hit three batters and never appeared comfortable.
"He's going to go out there and give us whatever he's got every time and for whatever reason this team's just given him a tough time and he's had a hard time in this stadium," St. Louis manager Mike Matheny said.
Westbrook survived a bases-loaded jam in the second to stay close, but by then Liriano had all the support he would need. His only real mistake came in the sixth, when pinch-hitter Tony Cruz led off with a triple and scored on Carpenter's single up the middle. A strikeout and a double play followed, and the Pirates broke it open in the seventh against relievers Marc Rzepczynski and Fernando Salas.
Garrett Jones started it with Pittsburgh's first sacrifice fly to the outfield since May 27 and Barmes clubbed a two-run double as the Pirates batted around.
Even with its best offensive showing since the All-Star break, Hurdle isn't so sure the Pirates made a statement.
"We're a confident team," he said. "I think we're a team whose confidence isn't built on its last game. It's not shattered by a losing streak. You continue to push through and that's what we've done from Opening Day until now."
NOTES: Pirates LF Starling Marte did not start after getting a planned day off in favor of Alex Presley, recalled from Triple-A on Monday after C Mike McKenry went onto the disabled list with a sprained knee. Marte entered in the seventh as a pinch hitter and singled. He is hitting just .131 (5 for 38) since July 20 ... The series continues with a doubleheader Tuesday. A.J. Burnett (4-7, 2.96 ERA) faces Lance Lynn (12-5, 3.98 ERA) in the opener with the Cardinals' Tyler Lyons (2-3, 5.51) starting the second game. The Pirates will not name a starter for the second game until Tuesday morning. ... Lynn was originally supposed to start the second game, but Matheny moved him into the matchup against Burnett because he wanted a more experienced pitcher to take on Pittsburgh's ace.
If particles of light have mass, a small but distinct possibility, they may not live forever?and some fundamental theories would have to be modified, too

REMNANT OF THE BIG BANG, the cosmic microwave background radiation as measured by COBE, reveals temperature fluctuations of the early universe.Image: NASA
We?ve long understood black holes to be the points at which the universe as we know it comes to an end. Often billions of times more massive than the Sun, they...

The notion of the speed of light as the cosmic speed limit is based on the assumption that particles of light, called photons, have no mass. But astrophysical observations cannot rule out the slim chance that photons do have a tiny bit of mass?a prospect with wide ramifications in physics. For instance, if photons weigh nothing at all, they would be completely stable and could theoretically last forever. But if they do have a little mass, they could eventually decay into lighter particles. Now, by studying ancient light radiated shortly after the big bang, a physicist has calculated the minimum lifetime of photons, showing that they must live for at least one billion billion years, if not forever.
That lifetime may sound like an eternity, but to a photon traveling at light speed, it passes in a relative blink. Because of the time-dilation effect predicted by Einstein's special theory of relativity, a billion billion years on Earth feels like only three years to a photon, because it's traveling so fast.
If physicists ever do discover that photons have nonzero mass, and therefore limited lifetimes, then ?the notion of light-speed obviously wouldn't make much sense anymore," says study author Julian Heeck, a PhD student at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany." There would still be an absolute limit on velocities, but the photons would have to obey that law, too, and travel below the speed of light." Photons? speed would then depend on their wavelengths, and blue light would travel faster than red light. Photons released simultaneously from distant stars would arrive at Earth at different times, depending on their wavelengths.
A photon with mass would also necessitate modifications to the Standard Model of particle physics (which posits a massless photon), the Maxwell equations that describe electromagnetic waves and fields (photons are the carrier particles for electromagnetic force) and the laws describing interactions between charged particles. Because of this latter effect, observations of the sun?s magnetic field have already proved that the photon, if it weighs anything at all, must be extremely light. The current experimental limit on the possible mass of the photon is 10-54 kilogram.
To find the limit on the photonic lifetime, Heeck analyzed observations of the cosmic microwave background radiation?light pervading the universe that dates from a few hundred thousand years after the big bang?gleaned from the now defunct NASA's Cosmic Background Explorer (COBE) satellite, launched in 1989. This light fits a very specific pattern?called blackbody radiation, that tells scientists how intense the light should be, based on its wavelength. If any photons were decaying as they traveled across the universe, however, COBE would see less low-energy (redder) light than predicted by the blackbody radiation law, because red light would be expected to decay sooner than blue light. "If the photons come from very far away, say from the beginning of the universe, then they might have had enough time to decay on their way here," says physicist Emanuele Berti of the University of Mississippi, who has studied the mass of the photon but was not involved in Heeck's research. "That's the idea, which I think is very elegant."
But according to COBE's measurements, the cosmic microwave background appears to behave like a perfect blackbody. No low-energy light seems to be missing, indicating that very few photons, if any, have decayed since the big bang some 13.7 billion years ago. This analysis enabled Heeck to calculate that the minimum lifetime of a photon is 1018, or one billion billion, years.
India menjadi tuan rumah GP pertama kali pada 2011.
Grand Prix India kemungkinan akan dihapus dari kalendar Formula Satu tahun depan, kata bos F1 Bernie Ecclestone.
"Apakah India akan dilaksanakan? Mungkin tidak," kata Bernie di Grand Prix Hongaria, seperti dikutip kantor berita Reuters.
Saat ditanya apakah ada masalah dengan ajang balap di Greater Noida, dekat New Delhi, Ecclestone menjawab, "Sangat politis."
Ecclestone, yang memimpin Formula Satu selama puluhan tahun, menyusun kalendar dan biasanya mempresentasikannya di hadapan Federasi Otomotif Internasional untuk meminta persetujuan mereka setiap bulan September.
Ia saat ini harus memilih maksimum 20 dari 22 balap untuk dimasukkan ke kalender.
Rusia, akan memulai debut mereka di Sochi, Laut Hitam, menjelang akhir tahun dan sebuah GP lain di New Jersey adalah dua even baru yang direncanakan untuk 2014.
GP Austria juga direncanakan kembali diadakan setelah absen selama 11 tahun.
India pertama kali menjadi tuan rumah GP pada 2011 dan mendapat ulasan positif dari komunitas Formula Satu.
Tahun ini GP India sebenarnya dijadwalkan untuk diadakan pada 27 Oktober tetapi setelah pernyataan Ecclestone, dunia balap masih harus menunggu kepastian.
