In television technology trifecta of LED LCD, plasma, and LCD, which comes out on top? The subject of countless debates and diatribes, the better question is: which works best? Or more precisely, which works best for you?
When you cut through the hype and the fanboys, each tech has different benefits and costs. So to help you figure out which TV is right for your house, let's take a look at each one.
First, a BIG disclaimer: any article of this type is, by necessity, going to contain a lot of generalizations. In most of the categories below, there are likely one or two exceptions to each rule. It's great to find an outlier, but that's just what it is, an outlier. The "average" product featuring these technologies is going to perform as listed.
Second, some terminology.
Plasma TVs, made by Panasonic, Samsung, and LG, range in size from 42 inches to roughly 65 inches. There are some larger models (notably Panasonic's 150-inch), but for most people, they max out at 65 inches. Most are "600 Hz" which isn't quite the same as 120 Hz or 240 Hz LCDs (more on them in a moment). You can read more about it in What is 600 Hz?
LCD TVs range in size from a couple of inches, to 90 inches, and everywhere in-between. They're made by everybody. All "LED TVs" are actually LCD TVs, they just use LEDs as their light source, instead of the traditional CCFLs. There are very few CCFL (non-LED) LCDs on the market anymore. Since you might find a few off-brands that still use CCFLs (or you own a CCFL LCD and want to compare), we'll include them here separately. One of the most common features of higher-end LCDs is 120 and 240 Hz refresh rates which helps reduce the blurring of motion common with LCDs. You can read more about that problem and the solution in What is Refresh Rate?
You might ask yourself, at this point, why only three companies for plasma? When electronics companies started building their manufacturing plants for TVs, they faced a choice: make big "cheap" flat panels that can't go much below 42-inches (plasma), or build a more expensive factory that can make a wide variety of sizes, even though the bigger sizes will be more expensive (LCD). As production has increased, the larger LCD sizes have become more price competitive, so that distinction has disappeared. As such, you don't see a lot of companies investing in new plasma TV manufacturing. Not when an LCD factory can make everything from cell phone screens to 90-inch HDTVs (an over simplification, but you get the point).

Sony est une marque bien établie quand il s'agit de téléphones mobiles. Le récent lancement de la Sony Xperia ZR est un autre smartphone ajouté à la série Xperia. Transition de l'Xperia Z à Xperia ZR signifierait une meilleure technologie et de fonctionnalités. Voyons maintenant ce que ce téléphone a à offrir.

USP est un aspect majeur qui attire tous les utilisateurs de la technologie. Le plus grand point de Xperia Z de vente est la technologie qui rend l'eau de téléphone résistant. Cette technologie rend le téléphone étanche et même si le téléphone est en suspension dans l'eau pendant 30 minutes, puis vous pouvez également l'utiliser. C'est presque comme si vous pouvez même prendre ce téléphone dans la douche sans l'endommager.

Faisons maintenant un oeil à ce Xperia ZR a à offrir contre Xperia Z si l'on doit comparer les caractéristiques:

Résistance à l'eau

Le Sony Xperia ZR est équipé d'un écran étanche qui mesure 1,5 m. Ce téléphone dispose de la conformité de IP55 et 58 rend très étanche. Par rapport à l'Xperia Z vous serez surpris qu'il ne soit pas classé comme élevé quand il s'agit de la technologie d'étanchéité. Avec le Xperia ZR, vous serez en mesure de filmer des vidéos sous-marines et de capturer des images. Toutefois, si vous tentez la même chose avec Xperia Z, alors vous allez vous retrouver avec un smartphone entièrement non-fonctionnelle.

Forme et la taille

Conception et la forme des deux téléphones sont légèrement différentes. La forme donnée à Xperia Z est celui de type sandwich de verre. La conception de Xperia ZR est conçu en gardant différemment l'approche conventionnelle. Il est relativement plus petit en taille à mesure 131 x 67.4mm contre 139 x 71mm. Épaisseur mesurée est 10.4mm contre le Xperia Z avec 7.9mm. Cela signifie que le Sony Xperia ZR est plus épaisse. Cependant, le poids est légèrement inférieur à 140 g contre 146 g.

Afficher

L'affichage pour les deux téléphones varier légèrement. L'écran Sony Xperia ZR mesure 4,55 pouces contre le Xperia Z avec 5 pouces. Toutefois, les deux écrans sont grandes dans l'affichage, mais ce qui importe le plus, c'est la résolution. Xperia Z a une résolution forte de 1920 x 1080, la ZR mesure 1280 x 720. Xperia Z semble être mieux entre les deux car il est équipé d'une capacité Full HD. Le seul inconvénient, il semble avoir le contraste du noir qui n'est pas aussi sombre comme il se doit.

Capture d'images

Le Sony Xperia ZR a un appareil photo VGA monté avant que est de 0,3 mégapixels. Le Sony Xperia Z a une frontale de 2 mégapixels face à la caméra. Il est compréhensible que le téléphone mégapixels supérieur vous donnera une meilleure qualité d'image et de vidéo.

Mémoire interne

Si vous achetez le Sony Xperia ZR alors vous obtiendrez une mémoire interne de 8 Go de mémoire interne. Avec le Sony Xperia Z, vous obtenez déjà une grande mémoire de 168GB. La mémoire peut être un problème pour ceux qui stockent de la musique et des fichiers multimédias sur leur appareil mobile. Toutefois, les deux smartphones vous offrent le cadre de l'expansion de mémoire avec un slot pour carte MicroSD.

Lequel acheter?

Il n'ya pas beaucoup de différence entre ces deux smartphones phares de Sony. Cependant, quand il s'agit de la résolution et la taille de l'écran, il ne soit beaucoup. Tout utilisateur de la technologie serait mettre l'accent sur un meilleur affichage du contenu et des images plus nettes. D'autres choses comme meilleure option de mémoire de stockage interne est ce qui pourrait plaire aux utilisateurs qui stockent leurs médias sur les Smartphones. Si vous êtes prêt à faire des compromis sur le stockage, l'écran et la qualité de l'appareil photo, vous pouvez choisir d'acheter le Sony Xperia ZR. Une autre raison pour l'achat de ce téléphone peut être une curiosité pour filmer des vidéos sous-marines durant une plongée.

Before we settle as to whether soluble fiber is superior or the insoluble fiber is, let's get a clear understanding about what they are.

As the name suggests the soluble fiber is water-soluble. It dissolves completely in water. Whereas insoluble fiber doesn't dissolve in water. It is worth nothing that insoluble fibers in general have the characteristic of absorbing water. They don't dissolve in water, but they absorb water most of the time.

Even if you don't explicitly drink water along with your food consumption, there is plenty of water present in the food sources. When you eat foods containing soluble fiber, the fiber will dissolve in the water that is present in the stomach. It will either form liquid solution or it will form a gel or liquid paste.

Some of the soluble fibers form very viscous gel. Viscous gel in the stomach causes stomach to empty slowly. The slow emptying stomach will make you feel full sooner.

This viscous gel also binds or traps nutrients and causes delays and interference in nutrient absorption in the small intestine. One can imagine, this may not bode well as it may potentially interfere with the absorption of vital nutrients like vitamins and minerals.

Luckily it seems these types of fibrous gel doesn't hamper vital nutrient absorption. But it hampers bad cholesterol absorption up to certain extent. This means it helps reduce the blood cholesterol levels.

The viscous gel also seems to bind and trap simple carbohydrates. This means it would interfere with digestion and absorption of simple sugars. This would help with controlling blood sugar and insulin levels.

Although insoluble fiber doesn't dissolve in water, it also can form viscous substance. But most of the insoluble fiber doesn't form viscous gel. They rather swell in the presence of the water. So far the cholesterol lowering effects have only been attributed to the soluble fiber.

Another common characteristic of soluble fiber is the fermentability. Remember that neither soluble nor insoluble fiber is broken down by any of the digestive enzymes in the stomach or small intestine. This means the fiber reaches the colon pretty much intact.

Bacteria in the colon seem to thrive on the soluble fiber gel entering the colon. When bacterial ferment the fiber, they produce simple gases like hydrogen, oxygen and carbon dioxide. Along with the gases, they produce what is called short chain fatty acids. These fatty acids are absorbed through the colon wall into the blood stream.

It is not that the soluble fiber passes through the digestive tract without any caloric extraction. But we don't get full caloric content of these soluble fiber. First bacteria ferment them and consume the energy from these foods. Remaining energy is consumed by the human body when those fatty acids are absorbed. You can see soluble fibers have low caloric value in general.

There is more than what meets the eyes. Those short chain fatty acids seem to be playing very important role in boosting the host immunity. They also seem to have a role in preventing the colon cancer. But the research in that area is still in its primary stages.

Although some of the insoluble fiber also seems to be fermented by the bacteria in the colon and offer those same benefits through short chain fatty acids. In general it is the soluble fibers which are mostly fermented.

Majority of insoluble fiber just passes through the gastrointestinal tract pretty much intact. This means they have no caloric value. In theory you can eat a lot of food that are high insoluble fiber without seeing a direct caloric impact.

Unfortunately the foods high in insoluble fibers are not the most palatable of the foods. Example of food high in insoluble fiber is wheat bran. Many people say that wheat bran tastes like paper.

Insoluble fibers have a tendency to swell up in the presence of water. This causes to give bulk to the food passing through the intestine. Enough bulk is important in stimulating intestinal muscular movement. This property of the insoluble fiber helps reduce constipation as it makes food move with enough speed through the intestinal tract.

As you can see both types of fibers have their own benefits. Soluble fibers and some insoluble fibers which are more viscous have the benefit of reducing cholesterol levels and better regulating blood sugar levels. But they will contain some calories as the fermentation byproducts will eventually be absorbed in the colon.

The soluble fibers which are not viscous may not help with cholesterol reduction or blood sugar but will provide the immunity benefits and potential colon cancer benefits as long as they ferment in the colon.

The insoluble fibers will not help with cholesterol, blood sugar or immunity but they will help with constipation. Besides they have no caloric value as they would pass through the digestive tract pretty much intact.

Moreover in most of the natural food both types of fiber are present in varying degrees. One can choose supplements of specific type of fiber for specific benefits. Soluble fibers which are very viscous seems to have a larger number of benefits.
