Unlike a typewritten or word-processed " formal " will, where usually two disinterested witnesses are required to attest to the author's signing or " execution " of the document, a holographic will does not require any witnessing or notarization ( an accepted form of witnessed certification of authenticity ) in order to be a proper and valid testamentary instrument ( document ) having full legal force and effect.

Martin Seligman writes that " Unlike money, which has at most a small effect, marriage is robustly related to happiness ....

Unlike a high-fidelity loudspeaker, the Leslie is specifically designed, via reproduction of the Doppler effect, to alter or modify sound.

Unlike American full-contact karate, or point karate, clean hits are not counted in and by themselves, as the scoring depends entirely on the effect of the hits, not on the formal or stylistic appearance of the techniques.

Unlike most other anabolic steroids, THG also binds with high affinity to the glucocorticoid receptor, and while this effect may cause additional weight loss, it is also likely to cause extra side effects such as immunosuppression that are not seen with most other steroids.

Unlike chemotherapy for cancer the effect of PDT can be localised and specificity of treatment is achieved in three ways:

Unlike Treaty provisions and regulations, directives cannot have horizontal effect ( against another private individual or company ), as this is adjudged contrary to the principles of equality ( see Marshall v Southampton and South West Hampshire AHA ( 1986 )).

Unlike standard centrifugation, which in effect crushes the particles against the bottom of the centrifuge tube, the sucrose cushion method causes no mechanical stress and allows the collection of morphologically intact particles.

Unlike bony fish, there is no direct control of the pigment cells by the nervous system, and this results in the colour change taking place more slowly than happens in fish.

Unlike mainstream medicine, CAM often lacks or has only limited experimental and clinical study ; however, scientific investigation of CAM is beginning to address this knowledge gap.

Unlike individual groups, the GSO is not self-supporting and maintains a small salaried staff.

Unlike the typical hijackings of land vehicles or ships, skyjacking is not usually committed for robbery or theft.
