Question: Film speed is found from a plot of optical density vs. log of exposure for the film, known as the Dlog H curve or HurterDriffield curve. There typically are five regions in the curve: the base + fog, the toe, the linear region, the shoulder, and the overexposed region. For black-and-white negative film, the "speed point" m is the point on the curve where density exceeds the base + fog density by 0.1 when the negative is developed so that a point n where the log of exposure is 1.3 units greater than the exposure at point m has a density 0.8 greater than the density at point m. The exposure Hm, in lux-s, is that for point m when the specified contrast condition is satisfied. The ISO arithmetic speed is determined from:
Is there an answer to this question: What is the point at which density is 0.1 less than the base + fog?

Question: Classification of predators by the extent to which they feed on and interact with their prey is one way ecologists may wish to categorize the different types of predation. Instead of focusing on what they eat, this system classifies predators by the way in which they eat, and the general nature of the interaction between predator and prey species. Two factors are considered here: How close the predator and prey are (in the latter two cases the term prey may be replaced with host) and whether or not the prey are directly murdered by the predator is considered, with true predation and parasitoidism involving certain death.

Question: In 1998, two former Northwestern basketball players were charged and convicted for sports bribery as a result of being paid to shave points in games against three other Big Ten schools during the 1995 season. The football team became embroiled in a different betting scandal later that year when federal prosecutors indicted four former players for perjury related to betting on their own games. In August 2001, Rashidi Wheeler, a senior safety, collapsed and died during practice from an asthma attack. An autopsy revealed that he had ephedrine, a stimulant banned by the NCAA, in his system, which prompted Northwestern to investigate the prevalence of stimulants and other banned substances across all of its athletic programs. In 2006, the Northwestern women's soccer team was suspended and coach Jenny Haigh resigned following the release of images of alleged hazing.
Is there an answer to this question: What were 2 former Northwestern soccer players charged and convicted for in 1998?

Question: The standard PlayStation 3 version of the XrossMediaBar (pronounced Cross Media Bar, or abbreviated XMB) includes nine categories of options. These are: Users, Settings, Photo, Music, Video, TV/Video Services, Game, Network, PlayStation Network and Friends (similar to the PlayStation Portable media bar). TheTV/Video Services category is for services like Netflix and/or if PlayTV or torne is installed; the first category in this section is "My Channels", which lets users download various streaming services, including Sony's own streaming services Crackle and PlayStation Vue. By default, the What's New section of PlayStation Network is displayed when the system starts up. PS3 includes the ability to store various master and secondary user profiles, manage and explore photos with or without a musical slide show, play music and copy audio CD tracks to an attached data storage device, play movies and video files from the hard disk drive, an optical disc (Blu-ray Disc or DVD-Video) or an optional USB mass storage or Flash card, compatibility for a USB keyboard and mouse and a web browser supporting compatible-file download function. Additionally, UPnP media will appear in the respective audio/video/photo categories if a compatible media server or DLNA server is detected on the local network. The Friends menu allows mail with emoticon and attached picture features and video chat which requires an optional PlayStation Eye or EyeToy webcam. The Network menu allows online shopping through the PlayStation Store and connectivity to PlayStation Portable via Remote Play.
