where is the maximum possible exposure that does not lead to a clipped or bloomed camera output. Typically, the lower limit of the saturation speed is determined by the sensor itself, but with the gain of the amplifier between the sensor and the analog-to-digital converter, the saturation speed can be increased. The factor 78 is chosen such that exposure settings based on a standard light meter and an 18-percent reflective surface will result in an image with a grey level of 18%/2 = 12.7% of saturation. The factor 2 indicates that there is half a stop of headroom to deal with specular reflections that would appear brighter than a 100% reflecting white surface.
What does the sensor usually determine?
lower limit of the saturation speed

Jehovah's Witnesses believe that God's kingdom is a literal government in heaven, ruled by Jesus Christ and 144,000 "spirit-anointed" Christians drawn from the earth, which they associate with Jesus' reference to a "new covenant". The kingdom is viewed as the means by which God will accomplish his original purpose for the earth, transforming it into a paradise without sickness or death. It is said to have been the focal point of Jesus' ministry on earth. They believe the kingdom was established in heaven in 1914, and that Jehovah's Witnesses serve as representatives of the kingdom on earth.
When do Jehovah Witnesses believe the kingdom of heaven was established?
1914

One way to decrease stigma may be through the promotion of "TB clubs", where those infected may share experiences and offer support, or through counseling. Some studies have shown TB education programs to be effective in decreasing stigma, and may thus be effective in increasing treatment adherence. Despite this, studies on relationship between reduced stigma and mortality are lacking as of 2010, and similar efforts to decrease stigma surrounding AIDS have been minimally effective. Some have claimed the stigma to be worse than the disease, and healthcare providers may unintentionally reinforce stigma, as those with TB are often perceived as difficult or otherwise undesirable. A greater understanding of the social and cultural dimensions of tuberculosis may also help with stigma reduction.
As recently as what year were there no studies on how TB mortality is connected to stigma?
2010
