1. Shrinking Glaciers of Kilimanjaro |
The Shrinking Glaciers of Kilimanjaro: Can Global Warming Be Blamed? The Kibo ice cap, a "poster child" of global climate change, is being starved of snowfall and depleted by solar radiation Around the globe, mighty glaciers are retreating. In the European Alps and many other mid- and high-latitude locations, evidence clearly implicates global climate change—heat fluxes from warm air feeding processes that turn mighty glaciers into rivers of meltwater. High-altitude glaciers in the tropics are melting too; the area of the ice cap atop Kilimanjaro in tropical East Africa has shrunk more than 90 percent in a century and become a global-warming poster child. But Mote and Kaser say that the Kilimanjaro glaciers are not melting but sublimating—turning straight to vapor—under the direct action of solar radiation at temperatures that remain below freezing. Whatever is happening elsewhere, Kilimanjaro’s ice seems not to be succumbing to climate change. http://www.americanscientist.org/template/AssetDetail/assetid/55553 |
2. The Best Time to Exercise |
Contrary to popular belief, women aren’t the only ones with biological clocks. We all have them, and heed their ticking on a daily basis. If you are a regular exerciser, you may have already determined your most productive time to exercise and follow a routine that works best for you. On the other hand, if your exercise time varies from day to day, and it’s wearing you out instead of pumping you up, you may be interested in the work of scientists who are studying the proverbial internal clock and how to best determine what time of day you should schedule your workouts. Rhythm: It’s not just for dancing The rhythms result from the firing rate of neurons. They have conformed to our 24-hour light-to-dark cycle, and may be regulated and reregulated each day according to the environment. Warm is better Body temperature is at its lowest about one to three hours before most of us wake up in the morning, in contrast to late afternoon when body temperature reaches its peak. Studies have consistently shown that exercise during these late-in-the-day hours produces better performance and more power. Muscles are warm and more flexible, perceived exertion is low, reaction time is quicker, strength is at its peak, and resting heart rate and blood pressure are low. Don’t fix it if it’s not broken And though it has been suggested that morning exercise may put some people at higher risk for heart attack, further research indicates that there is simply a generalized increased risk of heart attacks in the morning. If your schedule favors an early workout, emphasize stretching and a good warm-up to insure that your body is ready for action. Other considerations Though training at any time of day will raise performance levels, research has shown that the ability to maintain sustained exercise is adaptive to circadian rhythms. In other words, consistently training in the morning will allow you to sustain exercise during a morning marathon longer than if you train in the evening. |
3. How To Interpret Email Open-Rates |
When it comes to email marketing, the favorite statistic is the open-rate. It is considered as being the perfect indicator of how their mailings are received. This metric is important in judging the success of your email campaigns and newsletters. Your task is not only to get the email there but to ensure that it is opened. If your aim is to have your recipients read your email, then you have to achieve a high open-rate. This article will help you in getting a broad understanding about open-rates, how they are determined and whether they are reliable. How is open-rate determined? If you use email marketing tools to send emails and newsletters to your audience, then the job of establishing the open-rate is not a major issue. The tracking feature of your email marketing solution counts the number of ‘unique opens’, which implies that list members are never calculated twice, despite of the fact that they open the email more than once. Invisible graphics written in HTML are used to track the open-rate. They are placed on the server and when a list member opens and views your email, the graphic is downloaded. All downloads are spotted and the open-rate is subsequently obtained. Are open-rates reliable? The open-rate gives you a good estimate of the number of people who are opening your emails. However, two attributes, namely the ‘false negative’ and ‘false positive’ are involved in the ‘open-rate’ jargon, which can cause irregularity and unreliability. * False Negative In case the email is downloaded from the server and then viewed offline, it will not be tracked and counted as the graphic has not been downloaded. A false negative occurs as the open-rate is actually higher. You therefore cannot link the success of your email campaigns to only the open-rate. Other metrics should be used in parallel. |
