Deafness In Egypt
According to The Deaf Unit Cairo, there are approximately 1.2 million deaf and hard of hearing individuals in Egypt aged five and older. Deafness can be detected in certain cases at birth or throughout childhood in terms of communication delays and detecting language deprivation. The primary language used amongst the deaf population in Egypt is Egyptian Sign Language (ESL) and is widely used throughout the community in many environments such as schools, deaf organizations, etc. This article focuses on the many different aspects of Egyptian life and the impacts it has on the deaf community. Language emergence The primary sign language used throughout Egypt is Egyptian Sign Language (ESL) which emerged around 1984 when the National Association of the Deaf created an online dictionary. According to Ryan Fan in ''Verb Agreement, Negation, and Aspectual Marking in Egyptian Sign Language'' the only data documented in regards to Egyptian Sign Language are within the DVD dictionary publis ...

Egyptian Sign Language
Egyptian Sign Language is a sign language used by members of the deaf community in Egypt. Although there are no official statistics on the number of deaf people or the number of people who use Egyptian Sign Language as their primary language, Gallaudet University's library resources website quotes a 1999 estimate of 2 million hearing impaired children, while a 2007 study by the World Health Organization places the prevalence of hearing loss in Egypt at 16.02% across all age groups. Egyptian Sign Language is not formally recognized by the government. Linguistically, Egyptian Sign Language is not related to other sign languages of the Arab World, such as Jordanian Sign Language, Palestinian Sign Language, or Libyan Sign Language. Attempts at unification, creating an "Arabic Sign Language", have failed, as the unified form would be an entirely new language.

Cochlear Implant
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments. A CI bypasses acoustic hearing by direct electrical stimulation of the auditory nerve. Through everyday listening and auditory training, cochlear implants allow both children and adults to learn to interpret those signals as speech and sound. The implant has two main components. The outside component is generally worn behind the ear, but could also be attached to clothing, for example, in young children. This component, the sound processor, contains microphones, electronics that include digital signal processor (DSP) chips, battery, and a coil that transmits a signal to the implant across the skin. The inside component, the actual implant, has a coil to receive signals, electronics, and an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hearing Aid
A hearing aid is a device designed to improve hearing by making sound audible to a person with hearing loss. Hearing aids are classified as medical devices in most countries, and regulated by the respective regulations. Small audio amplifiers such as personal sound amplification products (PSAPs) or other plain sound reinforcing systems cannot be sold as "hearing aids". Early devices, such as ear trumpets or ear horns, were passive Amplifier, amplification cones designed to gather sound energy and direct it into the ear canal. Modern devices are computerised electroacoustic systems that transform environmental sound to make it audible, according to audiometry, audiometrical and cognitive rules. Modern devices also utilize sophisticated digital signal processing to try and improve speech intelligibility and comfort for the user. Such Digital signal processing, signal processing includes feedback management, wide dynamic range compression, directionality, frequency lowering, and noi ...

Auditory Brainstem Response
The auditory brainstem response (ABR), also called brainstem evoked response audiometry (BERA), is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp. The measured recording is a series of six to seven vertex positive waves of which I through V are evaluated. These waves, labeled with Roman numerals in ''Jewett'' and ''Williston'' convention, occur in the first 10 milliseconds after onset of an auditory stimulus. The ABR is considered an ''exogenous response'' because it is dependent upon external factors. The auditory structures that generate the auditory brainstem response are believed to be as follows: *Wave I through III – generated by the auditory branch of cranial nerve VIII and lower *Wave IV and V – generated by the upper brainstem *More in depth location – wave I and II originates from the distal and proximal auditory nerve fibers, wave III from the cochlear nucleus, IV showing acti ...

Language Deprivation
Language deprivation is associated with the lack of linguistic stimuli that are necessary for the language acquisition processes in an individual. Research has shown that early exposure to a first language will predict future language outcomes. Experiments involving language deprivation are very scarce due to the ethical controversy associated with it. Roger Shattuck, an American writer, called language deprivation research "The Forbidden Experiment" because it required the deprivation of a normal human. Similarly, experiments were performed by depriving animals of social stimuli to examine psychosis. Although there has been no formal experimentation on this topic, there are several cases of language deprivation. The combined research on these cases has furthered the research in the critical period hypothesis and sensitive period in language acquisition. Cases of language deprivation Genie The most well-documented case of a language-deprived child was that of Genie (wild child), G ...

Constitution Of Egypt
The Constitution of the Arab Republic of Egypt is the fundamental law of Egypt. The Egyptian Constitution of 2014 was passed in a referendum in January 2014. The constitution took effect after the results were announced on 18 January 2014. A constitutional amendments referendum was held from 20 to 22 April 2019. Background In July 2013, after the ousting of former President Mohammed Morsi, the military announced the schedule for the development of the constitution, with the vote to occur around the end of November 2013. Two different committees were involved in amending the 2012 constitution. The constitution replaces the Egyptian Constitution of 2012 which came into effect under Morsi. Contents The constitution adopted in 2014, like the constitution drafted under Morsi, is based on the Egyptian Constitution of 1971. The 2014 constitution sets up a president and parliament. The president is elected to a four-year term and may serve 2 terms. The parliament may impeach t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photoshop
Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc. for Windows and macOS. It was originally created in 1988 by Thomas and John Knoll. Since then, the software has become the industry standard not only in raster graphics editing, but in digital art as a whole. The software's name is often colloquially used as a verb (e.g. "to photoshop an image", "photoshopping", and "photoshop contest") although Adobe discourages such use. Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models including RGB, CMYK, CIELAB, spot color, and duotone. Photoshop uses its own PSD and PSB file formats to support these features. In addition to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Its feature set can be expanded by plug-ins; programs developed and distributed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HVAC
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and Sick building syndrome, healthy building conditions are regulated with respect to temperature and ...

Laser Marking
Laser engraving is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which in some cases, also includes color change due to chemical/molecular alteration, charring, foaming, melting, ablation, and more. The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out, giving it an advantage over alternative engraving or marking technologies where inks or bit heads have to be replaced regularly. The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser-sensitive polymers and novel metal alloys. The term laser marking is also used as a generic term covering a broad spectrum of surfacing techniques including printing, hot-branding and laser bonding. The machines for laser engraving and laser marking are the same, so that the two terms are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embroidery
Embroidery is the craft of decorating fabric or other materials using a needle to apply thread or yarn. Embroidery may also incorporate other materials such as pearls, beads, quills, and sequins. In modern days, embroidery is usually seen on caps, hats, coats, overlays, blankets, dress shirts, denim, dresses, stockings, scarfs, and golf shirts. Embroidery is available in a wide variety of thread or yarn colour. Some of the basic techniques or stitches of the earliest embroidery are chain stitch, buttonhole or blanket stitch, running stitch, satin stitch, and cross stitch. Those stitches remain the fundamental techniques of hand embroidery today. History Origins The process used to tailor, patch, mend and reinforce cloth fostered the development of sewing techniques, and the decorative possibilities of sewing led to the art of embroidery. Indeed, the remarkable stability of basic embroidery stitches has been noted: The art of embroidery has been found worldwide and ...

Computer Maintenance
Computer maintenance is the practice of keeping computers in a good state of repair. A computer containing accumulated dust and debris may not run properly. Dust and debris will accumulate as a result of air cooling. Any filters used to mitigate this need regular service and changes. If the cooling system is not filtered then regular computer cleaning may prevent short circuits and overheating. PC Components Keyboard The crumbs, dust, and other particulate that fall between the keys and build up underneath are loosened by spraying pressurized air into the keyboard, then removed with a low-pressure vacuum cleaner. A plastic-cleaning agent applied to the surface of the keys with a cloth is used to remove the accumulation of oil and dirt from repeated contact with a user's fingertips. If this is not sufficient for a more severely dirty keyboard, keys are physically removed for more focused individual cleaning, or for better access to the area beneath. Finally, the surface is wiped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deafness In Benin
In Benin, deafness affects 12,500 people out of their total population of 10 million. Since the late 1900s, there has been a growing emergence of resources, recognition, and support for the deaf people in Benin. The deaf community uses American Sign Language (ASL), Langue des Signes de l'Afrique Francophone (LSAF), and Langue des signes du Bénin (Benin Sign Language). The type of sign and how many people use each remain undocumented. However, in 1994, one of the first LSAF dictionaries was published in Benin. Cultural views, deaf rights, and the CRPD In Benin, there is a common misconception that deafness is a curse or misfortune brought onto families of deaf children. Other Beninese people believe that the deafness is hereditary and many deaf people are banned from marrying other deaf people.
