A web directory is not a search engine and does not display lists of web pages based on keywords; instead, it lists web sites by category and subcategory. The categorization is usually based on the whole web site rather than one page or a set of keywords, and sites are often limited to inclusion in only a few categories. Web directories often allow site owners to directly submit their site for inclusion, and have editors review submissions for fitness. A human-edited directory is created and maintained by editors who add links based on the policies particular to that directory. Human-edited directories are often targeted by SEOs on the basis that links from reputable sources will improve rankings in the major search engines. Some directories may prevent search engines from rating a displayed link by using redirects, no follow attributes, or other techniques. Many human-edited directories, including the Open Directory Project and World Wide Web Virtual Library, are edited by volunteers, who are often experts in particular categories. These directories are sometimes criticized due to long delays in approving submissions, or for rigid organizational structures and disputes among volunteer editors. Today submission of websites to web directories is considered as a common SEO (search engine optimization) technique to get vital back-links for the submitted web site. One distinctive feature of 'directory submission' is that it cannot be fully automated like search engine submissions. Another direction taken by some web directories is the paid for inclusion model. This method enables the directory to offer timely inclusion for submissions and generally fewer listings as a result of the paid model. They often offer additional listing options to further enhance listings, including features listings and additional links to inner pages of the listed web site. These options typically have an additional fee associated, but offer significant help and visibility to sites and/or their inside pages. Manual directory submission is a tedious and time consuming job and is often outsourced by the webmasters.

A carpet is any loom-woven, felted textile or grass floor covering. The term was also used for table and wall coverings, as carpets were not commonly used on the floor in European interiors until the 18th century. The carpet is produced on a loom similar to woven cloth and is usually a cut pile although looped pile carpets of woven construction are not unheard of. Normally many colored yarns are used and this process is capable of producing intricate patterns from pre-determined designs (although some limitations apply to certain weaving methods with regard to accuracy of pattern within the carpet). Cheap rugs and area rugs can be bought to meet customer’s satisfaction. These carpets are normally the most expensive due to cost of operation of the weaving loom, speed of manufacturing process and limited appeal of patterned carpets as floor coverings causing them to become more of a niche product. On a knotted pile carpet (formally, a supplementary weft cut-loop pile carpet), the structural weft threads alternate with a supplementary weft that rises at right angles to the surface of the weave. This supplementary weft is attached to the warp by one of three knot types (see below), such as shag which was popular in the 1970s, to form the pile or nap of the carpet. Knotting by hand is most prevalent in Oriental rugs and carpets. Unlike woven carpets, embroidery carpets are not formed on a loom. Their pattern is established by the application of stitches to a cloth (often linen) base. The tent stitch and the cross stitch are two of the most common. Embroidered carpets were traditionally made by royal and aristocratic women in the home, but there has been some commercial manufacture since steel needles were introduced (earlier needles were made of bone) and linen weaving improved in the 16th century. These are some of the valuable information regarding rugs.

The disorder of addiction involves the progression of acute drug use to the development of drug-seeking behaviour, the vulnerability to relapse, and the decreased, slowed ability to respond to naturally rewarding stimuli. Drugs known to cause addiction include illegal drugs as well as prescription or over-the-counter drugs. Addictive drugs also include a large number of substrates that are currently considered to have no medical value and are not available over the counter or by prescription. Both of them are highly disastrous and pathological too. One should not get addicted to any sort of drugs in their life. If they unfortunately fell into such addiction, then it will be too hard to get away from the same. But modern medicines and technological advancement helps people to get away from this habit sooner. These technology uses psychology in reducing the intention to take a particular drug. Proper rehabilitation programs are needed to be conducted for those addicted people in order to make them free from usage of drug. The addictive potency of drugs varies from substance to substance, and from individual to individual. Thus each individual are analysed and their psychological strength were taken in for consideration while deciding the proper programs like alcohol rehab program. Thus drug treatment therapy and alcohol rehab helps us in eradicating drug addiction.

A cigar is a tightly rolled bundle of dried and fermented tobacco which is ignited so that its smoke may be drawn into the mouth. Some cigars, especially premium brands, use different varieties of tobacco for the filler and the wrapper. "Long filler cigars" are a far higher quality of cigar, using long leaves throughout. These cigars also use a third variety of tobacco leaf, called a "binder", between the filler and the outer wrapper. This permits the makers to use more delicate and attractive leaves as a wrapper. These high-quality cigars almost always blend varieties of tobacco. Even Cuban long-filler cigars will combine tobaccos from different parts of the island to incorporate several different flavors.
In low-grade and machine-made cigars, chopped up tobacco leaves are used for the filler, and long leaves or even a type of "paper" made from tobacco pulp is used for the wrapper which binds the cigar together. This alters the burning characteristics of the cigar, causing hand-made cigars to be sought-after.
The majority of a cigar is made up of fillers, wrapped-up bunches of leaves inside the wrapper. Fillers of various strengths are usually blended to produce desired cigar flavors. In the cigar industry this is referred to as a "blend". Many cigar manufacturers pride themselves in constructing the perfect blend(s) that will give the smoker the most enjoyment of cigar. The more oils present in the tobacco leaf, the stronger (less dry) the filler. Types range from the minimally flavored Volado taken from the bottom of the plant, through the light-flavored Seco (dry) taken from the middle of the plant, to the strong Ligero from the upper leaves exposed to the most sunlight. Fatter cigars of larger gauge hold more filler, with greater potential to provide a full body and complex flavor. When used, Ligero is always folded into the middle of the filler because it burns slowly.
