Removing government poison from your water: very important








do you really  want to save your family and yourself?

Your water is being poisoned, that's a fact. They tell us they add fluoride to our water to help our teeth, is that supposed to be a joke? Fluoride is a neurological poison used by the Nazis to dumb down prisoners. What makes you think they are not doing the same to you? Well now at least you can filter out fluoride, and have some peace of mind. You can get the filter here as well as a meter that will tell you exactly how much is in your water supply.

Over 12 Health Benefits of Sesame Seeds and Sesame Oil


sesameseeds 265x165 Over 12 Health Benefits of Sesame Seeds and Sesame OilAn amazingly healthful food utilized for over 5,000 years, sesame may be one of the most potent, nutrient-dense medicinal foods still used today. Sesame seeds are not only praised for their nutritional content in seed form, but are also highly valued for their rancid-resistant oil. In fact, once you learn of the health benefits of sesame seeds, you may just find yourself stocking up on this ancient condiment.

Sesame Seeds Nutritional Profile

As mentioned, sesame seeds have a fabulous nutritional profile, granting their capabilities in fighting, preventing, and reversing illness and disease. The seeds are especially high in copper, manganese, calcium, and magnesium. But the value doesn’t end there. Here are some notable vitamins, minerals, and other nutrients you can expect to find in a 1 ounce (28g) serving of sesame seeds.
  • Manganese – 0.7 mg. 35% RDA.
  • Copper – 0.7 mg. 35% RDA.
  • Calcium – 277 mg. 28% RDA.
  • Iron –  4.1 mg. 23% RDA.
  • Magnesium – 99.7 mg. 25% RDA.
  • Tryptophan – 93 mg.
  • Zinc – 2 mg. 13% RDA.
  • Fiber – 3.9 g. 16% RDA.
  • Thiamin – 0.2 mg. 15% RDA.
  • Vitamin B6 – 0.2 mg. 11% RDA.
  • Phosphorous – 179 mg. 18% RDA.
  • Protein – 4.7 g.
Needless to say, the above nutrients, and others, help to make up the numerous health benefits of sesame seeds that have been experienced for thousands of years. It’s time to discover what exactly the Egyptians and other cultures around the world saw in these tiny seeds.
Here are over 12 sesame seeds health benefits.

The Health Benefits of Sesame Seeds

  • Promote Healthy, Beautiful Skin – Sesame seeds are full of zinc, an essential mineral for producing collagen and giving skin more elasticity. Zinc also helps damaged tissues in the body to repair. Sesame oil is also known to sooth burns and prevent skin related disorders.
  • Great for High-Protein Vegetarian Diet – Sesame seeds offer 4.7 grams of protein per ounce, giving them a perfect place in a high-protein vegetarian diet.
  • Sesame Seed Oil for Oral Health – One of the most prominent benefits of sesame seeds and sesame oil revolves around removing dental plaque and boosting oral health. By engaging in an activity known as oil pulling, which involves swishing oil around in your mouth, you can boost oral health and even whiten your teeth. One study showcases the oil pulling benefits on the oral level, where oil pulling with sesame oil was shown to reduce the amount of streptococcus mutants in both teeth plaque and mouth saliva, and boost overall health. (Click the next link to find out what oil pulling is and learn of oil pulling benefits).
  • Helps Prevent Diabetes – Thanks to magnesium and other nutrients, sesame seeds, and especially sesame oil, has been shown to combat diabetes. One study, published in 2011 in the American Journal of Clinical Nutrition, found that sesame oil “improved the effectiveness of the oral antidiabetic drug glibenclamide in type 2 diabetic patients”. Another study concluded that “substitution of sesame oil as the sole edible oil has an additive effect in further lowering BP and plasma glucose in hypertensive diabetics”.
  • Reduces Blood Pressure – As the above study concludes, sesame oil has been shown to lower blood pressure in hypertensive diabetics. Additionally, magnesium has been shown to help lower blood pressure – and sesame seeds are loaded with magnesium.
  • Promotes Heart Health - Further adding to the health benefits of sesame seeds, sesame seed oil can boost heart health by preventing atherosclerotic lesions. An antioxidant and anti-inflammatory compound known as sesamol, which also harnesses anti-atherogenic properties, is thought to be one reason for the beneficial effects. According to GreenMedInfo, sesamol has been shown to “possess over two dozen beneficial pharmacologically active properties, many of which may contribute to improving cardiovascular health”.
  • Protects Against DNA Damage from Radiation - Sesamol, a compound found in sesame seeds and sesame oil, has been shown in some studies to protect against DNA damaged caused by radiation. Further, sesamol has been shown to extend life in mice treated with radiation, partly by preventing damage to the intestines and the spleen.
  • Prevents Cancer – Not only do sesame seeds contain an anti-cancer compound called phytate, but the magnesium in sesame seeds also harness anti-cancer properties. One study published in the American Journal of Clinical Nutrition found that the risk of colorectal tumors decreased by 13% and the risk of colorectal cancer decreased by 12% for every 100 mg of magnesium taken in.
  • Boosts Bone Health - In addition to promoting healthy skin, zinc has also been shown to boost bone mineral density and bone health as a whole. One study, published in the American Journal of Clinical Nutrition, found a correlation between zinc deficiency and osteoporosis in the hip and spine area. What’s more, sesame seeds are a great source of calcium – a known trace mineral that is essential for bone health and preventing related conditions.
  • Boosting Digestive Health, Relieving Constipation – Sesame seeds are rich in fiber, which is known to pave way for a healthy digestive system and a healthy colon.
  • Provides Relief from Rheumatoid Arthritis – A mineral that is important for anti-inflammatory and antioxidant enzyme systems, copper is known for reducing pain and swelling associated with arthritis. Additionally, this mineral helps provide strength to blood vessels, bones, and joints.
  • Promotes Respiratory Health, Prevents Asthma – Thanks to the magnesium, sesame seeds are able to prevent asthma by and other respiratory disorders by preventing airway spasms.

Before You Buy a Wireless Internet Router

                                                 All wireless Internet routers might appear very much alike at first glance. In fact, many different wireless router models exist each with its own unique set of attributes. Use the checklist below to help decide which brand of wireless network router could work best for you.




Speed Ratings

Wireless routers typically advertise their speed in megabits per second (Mbps). Older Wi-Fi models offered 11 Mbps, mid-range 802.11g routers 54 Mbps and the latest 802.11n routers claim up to 450 Mbps. You may be tempted to only look at those routers with the highest Mbps rating. However, consider that the actual performance you will achieve in practice typically averages much, much lower than the maximum rating shown on the package. Furthermore, even high speed routers cannot directly speed up your Internet connection. The extra speed boost from a faster router may not be worth the extra cost.




Popular Models

An old adage says: "There is safety in numbers." Odds are, if many people are buying a particular product, it's serving a useful need. Top selling network gear tends to be current generation technology but not cutting edge. If you tend to play it conservative and run with the pack, check sales rankings at online retailers to start building your wireless Internet router short list.


Warranties

  Wireless Internet router manufacturers always provide a warranty package together with their equipment. The length and terms of these warranties vary widely. A better warranty may indicate a manufacturer more committed to support their products, while a lesser warranty could indicate a somewhat lesser standard of product quality or reliability. Always consider wireless router warranties when making your purchase decision.

Ignore (Most of) the Success and Horror Stories Told by Others

Countless consumers post opinions of their particular wireless Internet router to blogs, message boards, retailer Web sites and elsewhere online. For most brands of routers, a confusing mix of positive and negative anecdotes awaits you. Due to the complexity of home networking today, any given brand of wireless router that performs flawlessly in one person's home network could fail miserably in yours. Bottom line: Don't let someone else's experience, good or bad, sway your decision too much.

Brand Matching with Network Adapters

Consider purchasing a wireless Internet router of the same brand as at least one of your wireless network adapters. The benefit is a small one, but sometimes vendors will optimize communication protocols of their own equipment; you may see slightly higher performance. Vendors may also more thoroughly test compatibility with their own equipment. If you don't own any adapters (or newer laptops with built-in wireless), consider purchasing all of your WiFi gear together from the same manufacturer.





Size and Style

In many households, wireless Internet routers are installed in a visible central area of the residence. Purchasing a stylish router can make this an attractive addition to the decor that you will be proud to show family and friends. Routers vary in both size and shape. If you plan to install the router in a confined space, ensure you pick one with a suitable form factor. Small business owners and others interested in portability may likewise consider the class of "travel router" products.

Cost and Budget

Manufacturers sometimes offer rebates or other discounts from the full retail price of their wireless routers. Like an automobile, even if a router is last year's model, you may still find one with all the essential features you need. Shop around and you're more likely to land a good value for your money.

Samsung Galaxy Note 3 vs. Galaxy S4

Samsung's scorched earth mobile strategy has its share of critics. But if you're going to harp on Samsung for trying anything, everything, and all the spaces in between, you also have to acknowledge that the company has two major flagship smartphones that can each command the full attention of the tech world. How many smartphone makers can you say that about? Let's compare the latest versions of those two premier phones, the Galaxy Note 3 and the Galaxy S4.

Size

As big as the Galaxy S4, it's still pretty small compared to the Note 3
The Galaxy S4 is pretty big for a smartphone, but it still doesn't hold a candle to Samsung's hulking phablet, the Note 3. The Note is about ten percent taller, 13 percent wider, and five percent thicker.

Weight

The Note 3 is 29 percent heavier
No minor difference here either, as the Note 3 is a full 29 percent heavier than the GS4.

Build

Samsung threw us for a curve with the soft leather-like finish on the Note 3
This was our biggest surprise from the Note 3 event. Samsung ditched its much-derided glossy plastic, found on the GS4 and most other recent Galaxy devices, and replaced it with a faux leather backing. It's still made of plastic, but now it's soft and leather-bound notebook-themed.
We'll have to wait for more extended time with the Note to draw any real conclusions here, but, at the very least, we tip our hats to Samsung for trying something new in the build department.

Display

Ditto for screen size ... but at least you can know that you'll be getting a very sharp sc...
This is the biggest perk of carrying around a lumbering phablet like the Note 3. It gives you 29 percent more screen real estate than the (already big) display on the GS4. The latest phablet is pushing the boundaries between phone and tablet more than ever.
Resolution is identical. Though that has the smaller screen on the GS4 coming out a bit sharper, they're both likely well past the point where you'll be even remotely disappointed. Sharp text, crisp images, happy eyeballs.

Processor

Both phones ship in multiple versions: LTE/quad core, and 3G/octa core
No need to worry about performance on either of these phones. Both the LTE and 3G versions of each have some of the fastest mobile processors of 2013.

RAM

The Note 3 sports an impressive 3 GB of RAM
The 2 GB of RAM on the GS4 is a very solid amount, even over four months after the phone's launch. The 3 GB in the Note 3 is forging new ground.

Storage

After many people complained about the cramped useable storage in the 16 GB version of the...
The base model of the Note 3 doubles the base 16 GB in the Galaxy S4. Samsung's TouchWiz software, layered on top of Android on both phones, can really eat into that 16 GB, though, so that extra space could be a nice advantage for the Note.

Battery

The Note 3's battery holds more juice, but we'll have to wait to learn about actual uptime...
The Note 3's battery holds 23 percent more juice. We were impressed with the Note 2's uptimes, but we'll have to wait to get the low-down on the Note 3's actual battery life.

Cameras

Camera pixel counts aren't just close, they're identical
Megapixel counts are identical in both phones. The only true measure of phones' cameras, though, are sample shots. We'll have to wait a little while to put these two side-by-side.

Wireless

Yep, both phones will use speedy LTE data, as long as your local carrier provides it (and ...
Both phones sport LTE radios, though they also both ship in versions that max out on HSPA+. That split coincides with the different processors we showed you above.

Software

The Note 3 runs the newer version of Android ... for now
The Note 3 runs Android 4.3, but the GS4 is supposedly going to be updated to that latest edition of Jelly Bean in October.
Both phones run Samsung's TouchWiz software, which grows more and more bloated by the minute. Okay, maybe that's a bit harsh, but depending where you're coming from, you might find TouchWiz's feature list to mean more bang for your buck, or just overwhelming and unnecessary. On the GS4, we'd lean towards the latter. If the Note 3 is anything like the Note 2, though, we'd lean a bit towards the former.

Stylus

The Note 3 comes with its trademark S Pen stylus
... that's because the little plastic stylus known as the "S Pen" becomes something much more when TouchWiz's goodies are added to the mix. The pen not only gives you a finer level of precision, but TouchWiz has all sorts of note-related features up its sleeve. We're talking handwriting recognition, content scrapbooks, multiple apps on the screen at once, and anotated screenshots.
From where we stand now, the S Pen tricks (and TouchWiz tricks as a whole) are all a bit overwhelming. But you'll hear much more from Gizmag about the new Note's S Pen features in the coming weeks, after we put it through the paces.

Wrap-up

It's way too early to wholeheartedly recommend one of these mobile gizmos over the other. We've spent months with the GS4, but have only been briefly acquainted with the Note 3.
At this point, though, it looks like Samsung improved its phablet in all the right ways. Its screen is bigger and sharper, the device itself is a bit more compact, and its guts are full of the fastest mobile components you can buy in 2013. TouchWiz always walks that line between more of a good thing and gimmicky feature creep, so that verdict will have to wait. Ditto for battery life, camera quality, and how that soft backing feels over long stretches of time.
So stay tuned. In the meantime, though, you can whet your Note 3 whistle by checking out our post-event hands-on, with it and the Galaxy Gear smartwatch.

Wireless printing explained How to connect a wireless printer

Printers: Wireless printing explained How to connect a wireless printer

Wifi printer Plenty of printers have wi-fi, like the Canon Pixma MX870.
With a wireless printer it's easy to print from multiple computers, tablets and smartphones. You don't have to be in the same room, or in some cases the same building, as the printer to be able to print.
But before you can start printing you must first connect the printer to your home network - you'll need is a wireless router and a wi-fi printer.
Read our guide to buying a wireless router if you need one and check our reviews to find the best wi-fi printers.

Connect to a wireless network

Printers with colour screens display step-by-step instructions for setting up the wireless connection when you first turn on the printer. They're easy to follow, even if the screen is quite small and you're not overwhelmed with information - you can only progress one step at a time.
If you don’t set up the wireless connection during the start-up process you can set it up later. Look for the wireless set-up 'wizard' within ‘wireless settings’ or ‘networking’ in the printer’s menu.
There’s more that one way of connecting to a wireless network, and you may be offered a few different options for setting up the connection.

Wi-fi set up using WPS

If your printer and router are both compatible with Wireless Protected Setup (WPS) this should be an option in the printer’s network menu.
If so, when prompted, all you need to do is press the WPS button on your router and the corresponding button on the printer to wirelessly connect the printer to the network.

Wi-fi Auto connect

This feature is mostly available on Epson printers and is very easy to use. You can use it if computer is already set up on your wi-fi network.
Selecting Wi-fi Auto connect, the printer looks at the network your computer is on and then uses this information to connect itself to the wi-fi network. It may take a minute to connect, but it quick and done with a press of a button.

Connecting using a network key or PIN

If your printer doesn’t have WPS, you’ll probably have to enter a ‘network key’ – a series of numbers and letters – into the printer using the function buttons and screen on the printer in order to establish the connection between your printer and router.
Provided you haven't changed it, the network key will be in your router’s documentation, or on a label on the router.

Printers: How to buy the best printer Buying the best inkjet printer

Inkjet printer An all-in-one inkjet printer can do a bit of everything and prices start as low as £30.
Inkjet printers are the most common type of home printer. They tend to be smaller than laser printers, so they're more convenient for small home work surfaces.

Inkjets are cheaper

They're generally cheaper than laser printers. You can get an all-in-one inkjet colour printer (that can print, copy and scan) for as little as £25. All-in-one colour laser printers cost upwards of £100 and take up more desk space.
A4 inkjet printers that only print - sometimes referred to as 'single function printers' - are rare now.
You can still find a couple of models in high street stores, but with the low price of all-in-ones, even if you think you'll rarely use the copier function you won't be paying any more up front to have a copier in your printer.
Manufacturers make money from sales of ink, so they want to you use more of it, whether that's by printing or copying.

Inkjets are better for photos

If you want to print photos, an inkjet printer is your best option - they generally print better photos than laser printers.
Text speed isn't likely to be as fast as with a laser printer though.
You can find out which are the best inkjet printers in our inkjet printer reviews.

What makes a good inkjet printer?

  • Good print quality In our tests we print text, graphics and photos to find the best printers. 
  • Good print speed The average inkjet printer can print high quality text pages at around six or seven pages per minute.
  • Low ink costs The price of the printer is only the beginning. Ink cartridges can be expensive. We test the running costs of printers to find those that produce the cheapest prints.  Dismiss

Features to look for

  • If you regularly print photos Look for an inkjet printer with dual paper trays - this way you won't have to keep swapping paper in and out of the printer when you switch from printing glossy snaps to web pages or documents. Many printers aimed at photo printing include a preview screen, memory card slots and a USB connection on the front
  • Paper-saving measures Look for a printer with 'auto-duplexing'. This means you can set the printer up to automatically print on both sides of a page.
  • Want to print from more than one device? If you want to be able to print from a tablet or smartphone, look for a wireless printer. If you want to print from an iPad or iPhoe look for 'AirPrint compatibility'. Wi-fi printers also make it simple to print from more than one computer or laptop without trailing cables around. 
  • Scan to USB If an all-in-one printer has a USB connection, it's likely you can use the connection to print photos from a USB stick and also to scan documents on the printer directly onto the USB stick without having to turn on your computer. 
  • Automatic document feeder Some all-in-ones have an automatic document feeder (ADF). If you're scanning or copying multiple page documents you can put them into the ADF as a stack rather than having to manually lay them on the scanner one page at a time. However, many ADFs can't automatically scan or copy double-sided (duplex copy/scan). Our reviews let you filter to show models that have ADFs which can duplex copy and scan.
