API is secured. In Android apps hackers can reverse engineer an app to see what APIs it is using. Various authentication mechanisms can be used to secure an API such as OAuth, two way SSL, WS-security and so on. Sometimes |
you may find that you are not in charge of the API. Well in that case you can at least tell the company about possible pitfalls of not securing the API. Testing and Tweaking There are many types of tests |
that can be performed to check for security for example Static testing to check for source code vulnerabilities and Dynamic testing to check vulnerabilities once the app has been deployed to a live server to installed on the device. Employing |
Experts to do the Job If you feel that the mobile app security is really important and want to exhaustively test your app, you can always hire experts to do it. |
Alzheimer's disease is one of the most common causes of dementia. In Germany and Switzerland alone, around 1.5 million people are affected, and forecasts predict a doubling of the number of patients worldwide within the next 20 years. The accumulation of particular abnormal proteins, including amyloid-- (Aβ) among others, in patients' brains plays a central role in this disease. Prof. |
Frank Heppner from the Department of Neuropathology at Charit- and his colleague Prof. Burkhard Becher from the Institute for Experimental Immunology at the University of Zurich were able to show that turning off particular cytokines (immune system signal transmitters) reduced the Alzheimer's typical amyloid-- deposits in mice with the disease. As a result, the strongest effects were demonstrated after reducing |
amyloid-- by approximately 65 percent, when the immune molecule p40 was affected, which is a component of the cytokines interleukin (IL)-12 and -23. Relevant for human therapy Follow-up experiments also relevant for humans showed that substantial improvements in behavioral testing resulted when mice were given the antibody blocking the immune molecule p40. This effect was also achieved when the mice |
were already showing symptoms of the disease. Based on the current study by Prof. Heppner's and Prof. Becher's team, the level of p40 molecules is higher in Alzheimer's patients' brain fluid, which is in agreement with a recently published study by American colleagues demonstrating increased p40 levels in blood plasma of subjects with Alzheimer's disease, thus showing obvious relevance for |
WebMD Pet Health News Daniel J. DeNoon Louise Chang, MD Jan. 7, 2010 -- Pet African dwarf frogs from a single California breeder caused an 8-month salmonella outbreak in 31 states. The outbreak extended from California to Massachusetts. Of the |
85 cases, mostly in children, 16 were hospitalized, the CDC reports in its weekly MMWR publication. No deaths were reported. Although reptiles -- turtles in particular -- have been responsible for previous nationwide salmonella outbreaks, this is the first known |
multistate outbreak spread by amphibians. In this case, the amphibians were African dwarf frogs. The tiny creatures are less than 2 inches long from tip to tail. They live in water and are sold as aquarium pets. The frogs are |
hard to handle -- they tend to rest at the bottom of aquariums -- so most of the infections likely came from contact with the water in which the frogs swam. Nearly a third of contaminated households cleaned the frog |
aquariums in the kitchen sink, "posing a risk for cross contamination with food preparation areas," the CDC notes. Infections in Utah and Colorado came from frogs given away as carnival prizes. An infection in New Mexico came from a frog |
purchased in a pet store; one in Ohio came from a department store. Many of those infected didn't know frogs or other amphibians could carry salmonella. Many patients' parents had bought their kids frogs in order to avoid salmonella-carrying turtles. |
It took the CDC a long time to figure out that frogs were the source of the outbreak, as cheese-flavored crackers consumed by several early patients led disease detectives on a wild goose chase. Eventually, the frogs were traced to |
a single California breeder. DNA tests showed that salmonella in water tanks and gravel from frog habitats was the same strain that caused the outbreak. The CDC notes that there's no law against selling small frogs. To prevent infections, the |
CDC advises pet owners to wash their hands thoroughly after touching animals or cleaning aquariums. SOURCE:MMWR: Morbidity and Mortality Weekly Report, Jan. 5, 2009; vol 58: pp The Health News section does not provide medical advice, diagnosis or treatment. See |
What does it means The hard drive of the computer or the hard disk is the device where the computer stores the secondary memory. All the movies, music, and games in short everything stored by the user in the computer |
gets stored in the hard drive. The operating systems are also installed in the hard drive. So when the computer cannot find the hard drive during startup, proper startup becomes impossible since the windows cannot load. The no bootable device |
error is then displayed on the screen. Troubleshooting steps for desktops The no bootable device error normally gets fixed by rapidly pressing the F1 button. If it does not work, try and press F2. The user shall be then redirected |
to the BIOS setup. In the BIOS setup, if under the primary hard drive window, “none” is displayed, it means that the computer cannot recognize that there is a hard disk connected. This may be done due to some loose |
connections in the SATA cables which can be easily fixed. If still the no bootable device error persists, this means there may be some problem in the hard disk. Troubleshooting steps for laptops If the F2 button trick does not |
work, you should check whether the laptop is still under the warranty period. If it is, then the service provider must be contacted since it is not wise to open and try to repair laptops without proper training. If the |
warranty period has skipped and there is no option for free repairing, the user may try to repair the laptop himself to solve the no bootable device error. First of all, the power plug should be unplugged and the battery |
should be removed. Hold the power button for a few times and ground the motherboard, then if you don’t know how, get instruction manual from a proper laptop disassembly guide and remove and reconnect the hard drive. If there is |
no problem internally with the hard drive, the no bootable device error shall be fixed the next time you start the laptop. Why does reconnecting hard drive works? Sometimes in computers, due to some reason, the connection between the motherboard |
and the hard drive gets loose and the no bootable device error is displayed. Removing the plug from the port and inserting it back makes the connection firm and stable and the error is thus solved. Sometimes, simply restarting the |
computer works too. Now, let’s move on to the tricky part, i.e. steps for removal and reconnecting hard drive. Proper procedure for removal of hard drive - Hard drives are usually connected to the motherboard by SATA or IDE connectors. |
Before solving the no bootable device error you need to check with version of SATA is supported by your motherboard in case you have to get a new hard disk this is important. - Next, you have to properly handle |
the electronic components. Mishandling may cause damage to the component and also the chance that you may get electrocuted. You should make sure that you are properly grounded before opening and removal of components. It is best to power off |
the computer. Still, if you intend to do it while plugs are connected, use anti-electrostatic wrist straps and wear rubber sandals or shoes. - All safety precautions ensured the next step to fix the no bootable device error. Open the |
computer cabinet by unscrewing both sides. Locate the hard drive. If in any case you have two hard drives you have two try and remember on which one, the operating system is installed. Check and remember the proper cable connections |
and disconnect them. Remove the screws connecting the hard drive to the cabinet and remove the hard drive. - If you have not cleaned the inside of the computer for a long time, you will notice a lot of dust. |
This may also be another cause of loose connection of hard drive and causing the no bootable device error. Properly clean the inside of the computer with a very soft brush. Make sure to be careful which cleaning the CPU |
fan. - Now it’s time to reconnect the hard drive. Properly connect all cables either SATA or IDE to the motherboard and hard drive. Be extra careful and check the connections. If any ports are wrongly connected, there is a |
chance that your motherboard may get fried. After all connections are properly done, screw back the hard disk to the cabinet and screw back the lids of the cabinets again. Restart the computer and if luck favors, the no bootable |
device error will not be present this time. Your computer will run properly. Fixing the error by reinstalling the operating system Sometimes, the no bootable device error occurs due to crashing or certain mishap with the operating system. Reinstalling the |
operating system fixes this problem. You need to check whether this is happening first. Insert the operating system setup disk inside the DVD drive and restart the computer. When the BIOS screen appears, rapidly press F8. You will enter the |
windows installation menu. In every windows setup, it comes with proper instruction for installing windows. Follow the instructions and go to the hard drive option. If you see all the drives with their original size detected, you are sure that |
there is no problem with your hard drive. Select the drive where previously the OS was installed and format it. After formatting, rename it and select it to be the new directory for installing the OS. Proceed to the next |
option and you will see that the OS is automatically being installed. At a point of time you will be prompted to give the username and password. After the operating system is installed properly, which will take a maximum of |
30 minutes; if you restart the computer you will no longer face the “no bootable device” error. By following this guide, you can easily mend the no bootable device error. If any of the above solutions does not work, it |
If the mobile phone was not based on the use of EMF/EMR(Electromagnetic Fields/Electromagnetic Radiation) emitting transmitters and antenna, it could have been a great invention. This invention changed the world in less than 20 years. We now can communicate with each other whenever we want. We can be entertained wherever we are, we can even have video conversations and surf the internet when we |
are on the train or in the line for the dentist. Mobile phones have become a commodity. More than 4000000000 mobile phones were sold so far, and have become a need for most people, but at what cost? Thousands of 24-7 Radiation emitting mobile phone antennas have been built up, just outside our houses, in order to supply coverage to all of the phones. |
Most people are now holding a radiation device next to their brain for several minutes every day, and in some cases for several hours. People have become used to talking on the phone all the time and are now actually mobile phone addicts, talking about nothing for hours on their small radiating devices; madly checking their phones to see if they missed a conversation |
or SMS every couple of seconds. Smart phones emit RF EMR even when not in use. Applications that are installed on the smart phone communicates and passes data to and from the cellular network and emit RF EMR most of the day. Even if you are not using a cellphone from any kind you still are exposed to RF EMR from other people phones |
that use it or carry it next to you. The children and youth have adopted the use of mobile phones faster than the grownups and they are using them very heavily. The children and youth are suspected to be more vulnerable to electromagnetic radiation since their head is smaller, their skull is thinner, and their multiply more rapidly as their body is still growing. |
Today you can also buy mobile phone accessories, such as Bluetooth headsets, hand-free kits and other devices. Some of them, in some cases can increase the user exposure to EMR, and some, if used correctly can reduce the user exposure to EMR. All rights reserved No Radiation for You" (c) 1/1/2010" |
The U.S. is no longer the single largest consumer of the world's energy resources. That distinction now goes to China, according to the International Energy Agency. The IEA says that according to an analysis of its data for 2009, China, |
with a population of 1.33 billion compared with the U.S.'s 310.2 million, has outstripped the U.S. It's been known for some day that this day would come. But it happened faster than was forecast because China was hurt less by |
the global recession than the U.S. That it's taken until now for China, with its vastly larger population, to surpass the U.S. indicates how far the Asian nation still must go to reach the per-capita levels of consumption in the |
U.S. Put another way, it's a measure of the still relatively low living standards for many Chinese. Here's another way to look at it. Americans still use a lot more energy per capita than their Chinese counterparts. While the per |
Outside the Classroom: Partners in the Park – Grand Canyon Parashant Native Americans, Mormons, insects, tourists, animals, and, yes, bats have gathered around Pipe Spring in Utah throughout its existence. Currently, the preserved Mormon settlement around the spring has been designated as a national monument and serves as a tourist attraction. Whether it was Benn the Paiute Native American turned |
Park Ranger’s traditional Memorial Day performance that stopped tourists in their tracks or the continuum of stars that shone around the monument’s small body of water after the visitor center had closed and our student group returned at nightfall to catch bats, this was a poignant place. Pipe Spring National Monument in Utah is one of the only natural water |
sources for miles around. In the southwest, within the far-ranging landscapes and dramatic views, beauty abounds, but other than that, there is actually very little. The dry scrub grass, scant juniper trees, and a lizard or bird here and there create a very unique and barren type of natural environment. In a desert landscape, where nature is stripped down to |
its bare bones—rocks, dust, sun, and wind—the scarcity of water was a constant concern. So, at Pipe Springs, when our group of students from around the country gathered to help Professor John Taylor of Southern Utah University spread a thin net (called a mist net) around the small vestibule designed to hold water from the spring, we were helping with |
his research, but, really, we were treading on the fringe of an investigation of intellectual issues much deeper than catching bats. “How do you catch a bat?” John Taylor, wearing gloves made for baseball player, joked, “With batting gloves.” His joke resonated, but, as much of the small talk amidst the grandness of the landscape had a habit of doing, |
his words drifted away and allowed our thoughts to return to the solitude brought on by the huge open spaces of Southern Utah and the Arizona Strip. With no cell phone reception, no paved roads, and no stores on our some 70 miles of dirt road out to the Grand Canyon, the blankness evoked a search for something sublime and |
beautiful in this new and exciting environment, as well as a more internal journey, allowing time to examine many of my own thoughts and ideas. As I enter my senior year at Northeastern University, my academic experience is much like my trip with Partners in the Park through Grand Canyon. I have embarked on a path, at times more linear |
than others, but I am most grateful for the opportunities I have had to explore and shape and reshape my own thoughts in a figurative world much more far ranging even than the depths of Grand Canyon. In my experience at Northeastern, I have interned with The Emerald Necklace Conservancy, a nonprofit devoted to stewarding Boston’s Park system, traveled to |
the Grand Canyon with Partners in the Park, and I am now on my second co-op at the Boston Bar Association. This diversity of opportunities has allowed me to apply the knowledge I have garnered in my studies to practical, hands-on situations, as well as to the more abstract and very meaningful emotions and beliefs I had a chance to |
examine and reaffirm during my time in the southwest. Now when I am asked, “How do you catch a bat?” I think back on my invaluable experience with Partners in the Park and the numerous park officials I met and spoke with. Thanks to the opportunity I had to help John Taylor, I now know how a mist net can |
be used to catch bats, but, what’s more than that, I can think back to that experience and I can relate it to my own knowledge from my co-ops and classes and further relate it to my current work at the Boston Bar Association regarding legislation and my studies around Public Policy. Now that I know how a mist net |
operates, I can move on to new and more exciting questions, expanding my examination of Pipe Spring to look at it as far as its importance as a gathering place, a publicly managed entity, and a water source in the beautiful and overwhelming landscape of the Arizona Strip and Grand Canyon. While I found many answers and learned much through |
my trip to the Grand Canyon, I have much more searching and much more thinking to do as I assemble the spread out pieces I’ve begun to gather on my personal voyage. These are pieces I hope to gather in an attempt to address the complex questions of today’s world and, by continuing to build on the groundwork I’ve created |
Cancer workers are gearing up for World Cancer Day this week to raise awareness about a disease that kills hundreds of Northlanders every year. Northland Cancer Society area manager Margaret Curry said Thursday was World Cancer Day, a day that raised awareness of cancer and encouraged its prevention, detection and |
treatment. Ms Curry said the region had some of the highest cancer rates in the country - particularly for Maori - and raising more awareness of the disease was the start of reducing those statistics. Figures from 2005, the most recent available, show that while the New Zealand rate of |
new cancer diagnosis was 472 per 100,000, in Northland it was 531 for Maori and 490 for non-Maori. For the same year, the national cancer death rate was 201 per 100,000 population, in Northland it was 366 for Maori and 203 for non-Maori. The Cancer Society's latest research shows that |
skin cancer alone costs the health system more than $57 million a year, with malignant melanoma killing more than 200 Kiwis every year. Ms Curry said one of the saddest things about the disease was that up to 43 per cent of cancers could be prevented. She said they could |
be prevented through: providing a smoke-free environment for children; being physically active; eating a balanced, healthy diet and avoiding obesity; learning about vaccines for virus-related liver and cervical cancers and avoiding over-exposure to the sun. As well as raising awareness about the disease, World Cancer Day reminds people of what |
they can do to reduce the risks, Ms Curry says. "When it comes to the figures [for cancer] we are way up there and we are contributing to it by our behaviour." She said with its high Maori population, high number of people living in lower socio-economic circumstances and the |
unforgiving sun, Northland already had a number of high cancer risk factors. Ms Curry said early detection was one of the keys to fighting cancer but in Northland many people could not afford to get regular GP check-ups, while lack of knowledge could be another contributing factor. She hoped that |
Trying To Lose Weight? Study May Have Some Pointers ROBERT SIEGEL, host: From NPR News, this is ALL THINGS CONSIDERED. I'm Robert Siegel. MICHELE NORRIS, host: And I'm Michele Norris. |
There is good health news today for people who love to eat nuts - and bad news if you're a regular consumer of potatoes, whether they're baked or french fried. |
A new study from the Harvard School of Public Health followed more than 120,000 people over the course of as many as 20 years, to see what they ate and |
how it affected their weight. And some of the findings are surprising, including these: Nuts and yogurt were most closely correlated with weight loss. And potatoes of any kind, even |
just boiling them and eating them plain, caused the most weight gain. For more on the study, we're joined now by one of its authors. Walter Willett is a professor |
at the Harvard School of Public Health. Welcome to the program. Professor WALTER WILLETT (Epidemiology/Nutrition, Harvard School of Public Health): Great to be with you. NORRIS: We mentioned nuts and |
yogurt and potatoes. But can you tell us a little bit more some of the other foods you looked at, and how they affected weight gain or loss? Prof. WILLETT: |
In general, we found that highly refined foods - sugary beverages and potatoes - were related to greater weight gain on a diet. So that would include things like white |
bread and white rice. Sugary beverages are very important here because many people take multiple servings a day, so that is actually the number one problem if you look at |
the whole overall diet pattern. On the other side, foods related to lower weight gain were, not surprisingly, fruits - not counting fruit juices, though; they were on the bad |
side - vegetables, high-fiber foods, nuts and yogurt. NORRIS: I just went to go back to potatoes for a minute, because I'm sure there's someone who's listening to our conversation, |
thinking about serving mashed potatoes for dinner. Why do potatoes or refined carbohydrates lead to weight gain? Prof. WILLETT: There is a very strong hypothesis that it's because potatoes, since |
we cook them, are very rapidly broken down into sugar. It's quickly absorbed into the blood, removed rapidly by the action of insulin and in a few hours, we're hungry |
again. So they're not very satiating in the long run. Particularly problematic, of course, are potatoes that are made into french fries and potato chips because they're really designed to |
make us overeat. And unfortunately, many of us are susceptible to that seduction. NORRIS: But they are good. Prof. WILLETT: That's the problem. (Soundbite of laughter) NORRIS: Well, on the |
other hand, some of the foods that are good for us, like nuts and yogurt, why do they accelerate weight loss? Prof. WILLETT: For nuts, for some reason - this |
has been studied quite a bit. We don't totally understand it, but they seem to be very satiating. It's probably because we chew them for a while, and then they |
stay in our stomach for quite a while. They're a package of fat and fiber and a lot of micronutrients that's not rapidly absorbed... NORRIS: But there is a lot |
of fat in nuts. Prof. WILLETT: There is a lot of fat there, but as long as they're keeping us satisfied for quite a long time, calorie-for-calorie they make it |
easier to control our overall caloric intake. NORRIS: And yogurt? Prof. WILLETT: Yogurt, that was a bit of a surprise to us - in fact, probably the most surprising finding |
here. There has been a lot of work in recent years on how the types of bacteria in our colon influence our state of inflammation and weight gain. So it |
may well be that the healthy bacteria in the yogurt are helping change the mix of bacteria in the colon and influencing weight. NORRIS: Now, professor Willett, when I go |
to the grocery store and I look in the dairy aisle, where they sell all that yogurt, a lot of it has a lot of sugar in it. Prof. WILLETT: |
That's right, and I think it's better to stay with a natural yogurt without added sugar. NORRIS: I want to ask about one of your particular findings because I hail |
from the Midwest, and I happen to like cheese. And I know one of the other producers working on this has a thing for a cheese as well. And I |
was delighted to see that cheese doesn't actually appear to have that much impact on our overall weight gain - which is surprising in itself, 'cause I know that cheese |
often does have a very high fat content. Prof. WILLETT: Right. I'm from the Midwest, too. So that looked pretty good to me. It is interesting that just because a |
food has fat doesn't mean that it's going to be fattening. I think one of the lessons out of this analysis is, to a large extent, how satisfied we are |
