The dark adaptation test measures the threshold of sensitivity of the retina to a small spot of light after the patient is placed in the dark and typically is measured over a 40 [minute] period.... Any panretinal disease, which causes rod damage or dysfunction may cause night blindness and can be quantified by the dark adaptation test. Measuring the final threshold in several retinal locations after 40 [minutes] of dark adaptation is a good screening procedure for assessing night vision. This test is useful in functionally accessing complaints of night blindness in cases where dysfunction at night has vocational significance.  3, record 1, English, - dark%20adaptation%20test

Reasonable expectation of privacy-Section 8 of the Canadian Charter of Rights and Freedoms provides protection against unreasonable searches and seizures. The Supreme Court of Canada has defined as a "search" any state action that engages a reasonable expectation of privacy. The concept of a "reasonable expectation of privacy" is therefore employed to determine whether, as a threshold matter, the protections of Section 8 are engaged. The degree of this privacy expectation is then used in the balancing exercise to determine whether a law authorizing a search is reasonable – i. e. whether it is justifiable in light of the state's objective, taking into account any safeguards provided for in the law.  2, record 3, English, - reasonable%20expectation%20of%20privacy

Growing Degree Days. The underlying idea is that development does not occur unless the temperature exceeds a certain minimum threshold value or base temperature. The base temperatures are determined through research and experimentation and are different for different organisms. It has been found that there are many other factors, which may influence the actual temperature the organism is experiencing or that may influence their growth and development. For instance it is possible that the organism may be experiencing a temperature a few degrees more or lesser than that recorded depending on weather it spends most of its time in the shade or under direct sunlight. Precipitation and the presence of weeds may also indirectly influence the growth and development of insects and plants. The fertility and nutrient content of the soil is directly related to the growth rate of insects and plants. In light of these many factors and some other scientific considerations a base temperature of 50 degrees Fahrenheit is considered acceptable for all plants and insects.  2, record 11, English, - growing%20degree%2Dday

The general thrust of the new ICAO draft is to establish a threshold of 60 minutes’ flying time at single-engine speed from an alternate, beyond which twins may not operate unless they have demonstrated a certain standard of powerplant reliability and systems redundancy. Existing rules date from the late 1940s and are recognised to be outmoded in the light of current technology. ICAO's provision does not specifically mention turns, but has the effect of preventing them from operating more than 90 minutes’ flying time(with both engines operating) from an alternate-the so-called "90-minute rule".  1, record 21, English, - 90%2Dminute%20rule

Le projet de l'OACI se fonde sur la notion de "seuil" d'éloignement maximal d'un terrain de déroutement (60 minutes de vol à la vitesse de croisière sur un moteur), seuil que les bimoteurs ne pourront franchir qu'à la condition d'avoir fait la preuve d'un certain degré de fiabilité de leurs groupes propulseurs et de redondance de leurs systèmes. Les règles actuelles datent de la fin des années 1940 et tout le monde reconnaît qu'elles sont dépassées. Le projet de l'OACI ne mentionne pas spécifiquement les bimoteurs, mais il a pour effet que ceux-ci ne devront jamais se trouver à un moment quelconque à plus de 90 minutes de vol (sur deux moteurs) d'un terrain de dégagement.
