artificial light sources for photography Light‚ is the main ingredient in a photograph. There are of course other ingredients: time‚ composition‚ subject matter‚ emotion and your unique style‚ but light is the thing that makes photography work. Light is the thing that early inventors had to hold or fix‚ in order to make a photograph stick around. We call nature’s light‚ natural or available. Think of sunlight or moonlight. There are four common types of artificial light sources used in photography

Valentina Vilkova‚ a senior scientific researcher at the Centre for Political and Economic History of Russia of the Independent Russian institute is an integral documental presentation of the power struggle in Russia from 1923-1924. It aims to enrich source material with these new documents unknown in Russia to allow for certain corrections of historical concepts in that period. The value of this book lies in how Vilkova uses recently uncovered archival materials from the 1923-1924 period in Russia

Many scholars have attempted to explain criminal behaviour by identifying a genetic trait or other biological causes or indicator for criminality (Cullen and Agnew‚ 2011). Ellis and Walsh (2011) argue that while there is not a single “criminal behaviour” genetic trait‚ there are genetic trait that are associated with crime. They further suggest that these traits might provide evolutionary advantages to their holders in some circumstances. For example‚ traits such as deception and cheating would likely

For the past few decades‚ the study of genetics has given scientists an ability that we as a species never had before-- the ability to directly modify our genetic makeup. With this scientific breakthrough‚ the possibilities are endless with real world implications. On a darker note‚ this also means that genetic modification has the ability to adversely affect humans in ways we cannot imagine. This gives rise to an important question‚ how ethical is the genetic modification of humans? Before we can

Genetic models to explain heterosis Traditional genetic analyses of heterosis are based on the quantitative effects of the genes between two opposite inbred lines. Three major classical genetic models have been suggested to explain the hybrid vigor: the dominance hypothesis explains increased vigor to the action at multiple loci of favorable dominant

Reading for children has been seen to decrease dramatically as a child progresses from elementary to high school‚ possibly due to the increase of outside influences like cell phones that take much of a student’s time in the form of social media. The ideas in Contagious can be applied to improve literacy skills for both middle and high school students by creating school programs that utilize the

How do genetic and biological factors (i.e.‚ nature) interact with environmental conditions (i.e.‚ nurture) to increase or decrease risk for antisocial behavior? A14: Although both biological and environmental conditions are powerful predictors of antisocial behavior and drug abuse‚ neither are “causal” in a deterministic sense – they are probabilistic. The intensity and frequency of exposure to negative environmental conditions‚ and the number and severity of internal risk factors present
