Jump to navigation. Veena Singla aims to create healthier indoor environments by limiting the use of toxic chemicals in the built environment and everyday products. Her research focuses on understanding how toxic chemicals threaten the health of vulnerable populations, including pregnant women, children, and workers, through an interdisciplinary approach incorporating environmental health, exposure science, public health, and policy expertise.
Singla specializes in the communication of complex scientific information at the intersection of research and policy and has testified to the Consumer Product Safety Commission, the Alaska state legislature, and the San Francisco Board of Supervisors. She completed a postdoctoral teaching fellowship at Stanford University and was an adjunct faculty member at the University of San Francisco.

As I was frantically cleaning my apartment last month in preparation for a visit from my parents, I paused for a moment to stare at the dark smudge on the damp cloth I was dusting with. Never in my wildest dreams did I imagine that little dust smudge contains a whole universe of toxic chemicals—chemicals that pollute the globe and build up in wildlife and humans, that can cause cancer, or are linked to birth defects in babies.
Never, that is, until I collaborated on a new study to put together all the data we have on chemicals in U. Dust is the common congregation place for all kinds of chemicals that migrate out of everyday products in our homes—flooring, furniture, personal care products, cleaning products, and myriad others.
So our idea was that by looking at dust, as well as the individual chemicals in dust, we could reveal the bigger picture of chemical contamination in the home—just like individual dots in an Impressionist painting create a larger image. Hazardous chemicals migrate out of every day products and building materials and collect in dust.
The dust in U. These chemicals pose health hazards including cancer, hormone disruption, and toxicity to the reproductive system. For each chemical, we calculated the average level found in dust, estimated human intake and identified health hazards.
We looked at each chemical in household dust from three different angles: how much is in the dust, how much gets into us, and what the health hazards are. But no matter which way we looked at it, phthalate and flame-retardant chemicals stood out as top offenders. Phthalates are used in numerous plastic and vinyl materials, as well as personal care products and cleaning products.
Flame retardants are chemicals found in furniture, electronics, and building insulation. These products all shed phthalates and flame retardants into dust. To better understand how risky these chemicals in dust might be, we completed an additional analysis separately from the published study.
Unfortunately there are not standards established for chemicals in household dust, so we looked for something else we could compare to.
Because exposure to dust is a lot like exposure to soil, we used soil-screening levels established by the U. Environmental Protection Agency for sites contaminated with chemicals as a comparison. These soil-screening numbers reflect the levels at which a chemical might pose health risks to people, and thus exceedances require further investigation. The EPA calculates two different numbers, one for cancer health risks and another for non-cancer health risks, such as developmental or reproductive toxicity.
Note that many chemicals in our study do not have soil-screening levels established, but we did the comparison for the ones that did. The graphs show the average dust concentration we calculated in our study by pooling data from individual studies circlethe highest maximum level of the chemical found in each individual study triangleand the EPA screening level black line.
Shockingly, the levels of some phthalates and flame retardants in U. DEHP is also ubiquitous in U. This means that if an EPA site manager tested the dust in a typical living room, they would be concerned about the level of DEHP found there! Exceedance of the EPA screening levels for this portion of the population is a concern. With recent reforms to the federal Toxic Substances Control Actthe EPA finally has the opportunity to start protecting the public from toxic chemicals. In the meantime, there are a number of steps you can take to protect your families from toxic dust, including:.
And please take action now on phthalates. Urge the U. Toddlers and gymnasts have high levels of flame retardant chemicals; California moves on regulating some products.
New study suggests product choice can lower levels of harmful hormone-disrupting chemicals in our bodies. We will keep you informed with the latest alerts and progress reports. About the Authors. Want to join the fight?The anterior tibial vein is a vein in the lower leg.
In human anatomythere are anterior two tibial veins. They originate and receive blood from the dorsal venous archon the back of the foot and empties into the popliteal vein. The anterior tibial veins drain the ankle jointknee jointtibiofibular jointand the anterior portion of the lower leg. The two anterior tibial veins ascend in the interosseous membrane between the tibia and fibula and unite with the posterior tibial veins to form the popliteal vein.
Like most deep veins in legs, anterior tibial veins are accompanied by the homonym arterythe anterior tibial arteryalong its course.

The booking agents were responsive when we had questions.
The information provided was excellent. The tour guides and the company's you contracted with are without exception outstanding. I would recommend your company to anyone who is planning a Scandinavian trip We loved Iceland, the people and we have a myriad of experiences to reflect back on.
What a fantastic holiday. It worked smoothly from beginning to end. Thank you Nordic Visitor and in particular Dagny. The overall experience exceeded our expectations. We loved the attention to detail.
Annie obviously understood what type of planning we wanted. We were able to be spontaneous if we saw something that we wanted to include. Many of the owners of accommodations told us how happy they were to be working with Nordic Visitors.
The travel guide was sturdy, survived the trip in one piece, even served as a plate for our lunches eaten in the car as we would return from a walk. We took scotch tape along to mend the map, it's pretty big to handle in the car.
And a highlighter to add stops and reminders to help us when we start putting our pictures together. But, the travel guide will be the most helpful when it comes to putting our travel album together. The places we stayed at were so very nice. I don't know how we would rank them. The owners were so very nice and helpful. Giving us directions and making recommendations on dinners and even making reservations for us. The locations of the accommodations were usually within walking distance of village centers.
Picking up our rental car was speedy and well organized. A new car was ready for us and they took the time to go over key points of the car.Nöjd publik
Excellent service and a well organised trip. The ease of getting about was further helped by the amazingly good English spoken by almost everyone we interacted with, even in the more remote areas of the country. I'd happily travel with Nordic Visitor again, and indeed hope to at some stage. We really loved this trip and all your help. Your suggestions were always great. The fact that you called a hotel to make last minute arrangements and then called us to explain, was so appreciated.
I can't say enough about our trip, all your help, and of course the country of Iceland.

Bet365 is another of the sports betting giants that has recently made the move into esports betting. With a solid selection of games and a very large selection of markets, it is one of the better sites to use for your esports betting needs if you like to cover multiple games. Bet365 does have a slightly unfriendly website design that appears to heavily use Flash, meaning that there are simpler options available. All of the top esports titles are supported, mostly with many matches and more markets than most competitors.
In-play betting is also supported, but only with limited matches and markets, and many in-play games have a lot of downtime on markets thanks to betting suspension. The site does, however, feature some solid welcome offers for new customers and it has a large amount of deposit and withdrawal options. Much like many other competitors, the esports section of Bet365 is a part of the traditional sports betting section. While not a major focus, it receives better treatment than many sites and can easily be found.
In order to place a bet, you must be logged into your Bet365 account. From the main sports betting page you must select esports from the menu on the side, which will bring up the main esports page.
This will then display all the competitions that are available and the markets that are available for that competition. Irritatingly, individual matches are not shown on this page so you need to know what competition the match is a part of in order to find it. Once you have selected the competition and the market from this page, you will be shown a page with all the available matches, and the teams that can be selected for your chosen market along with the odds.I could not find any information in the vignette.
A couple of people have also suggested this feature to me. I'll put it on the long term todo list (I'm pretty busy in the next few months) but for reference, what exactly would you want this to do.
For example it could behave like predict. In flexsurvreg, that could be the mean or the median of the fitted survival distribution, but a problem might be that these are not always available analytically, and numerical integration would be needed. Generalized gamma: I think the mean has a complicated form, but you could get the median with qgengamma(0. In my case, y is say insurance premium, i.
I have two covariates x1 and x2, e. I model as above with the generalized gamma and flexsurv. I now want to predict the premium for new customers.

When I do this as above with the matrix multiplication of the covariates I get a prediction not on the scale of the response, it is not dollars. I actually have no clue what that really is. How can I make it to real dollars. That would be some point estimate given the covariates, as you say. Predict usually just returns a vector of predicted values, so it is a subset of what is needed for summary. Though right now, summary.
Reply to this email directly, view it on GitHub, or mute the thread. I never saw the value in having shorter output in the print method, e. I think some of those methods are a relic from the S-Plus days when most people would work on text terminals.
We have much better tools these days for auto-generation of reports and so on, where people can arrange the output in a way that's useful to them.
I predict using df. I am kind of "abusing" your package for fitting a GLM using the generalized gamma distribution you define in the package.The best media links are organic media links generated from some sort of PR or content production.
