not all values of literary texts should be sought for in their artistic aspects . there have been many lower-ranked literary texts that have shed light on numerous scientific, historical, social, and cultural issues. although poetic views are involved while raising such issues, it needs to be taken into account that not all poets have perceived the scientific principles of the topics tackled in...

Over the past few years, properties of nonclassical states o f light as well as different methods for their production have been widely discussed. In most works, both theoretical and experimental ones, monochromatic continuous-wave pump fields are considered to obtain the nonclassical light, including squeezed states [ 1 ]. Several papers are also devoted to problems of squeezed light pulses [ ...

There are many historical manuscripts written in a single hand which it would be useful to index. Examples include the early Presidential papers at the Library of Congress and the collected works of W. B. DuBois at the library of the University of Massachusetts. The standard technique for indexing documents is to scan them in, convert them to machine readable form (ASCII) using Optical Characte...

this paper examines colorful modes of narrative discourse representation , especially stream of consciousness versus interior monologue from a narratological point of view and through some references to iranian and western literary works . the problem is that these two modes are employed as though they were the same , but the fact is that they are not . this has made it difficult to make clear ...

Lighting is an essential component of visually rich cinematographic images. However, the common computer graphics light source models, such as a coneshaped spotlight, are not versatile enough for cinematographic-quality lighting. In this paper we describe the controls and features of a light source model for lighting computer graphics films. The model is based on generalized light cones, emphas...

Even though scanning electron microscopy (SEM) is now needed to identify some species of diatoms, the majority of identifications and quantification of these organisms in ecological works is accomplished with a light microscope, using transmitted light optical methods. In this paper we demonstrate the use of interference reflection contrast (incident light) for the examination of diatoms, a met...

Cold exciton gases can be implemented in coupled quantum well structures. In this contribution, we review briefly the recent works on spontaneous coherence of cold excitons and on trapping of cold excitons with laser light.

Aim Clinicians may become quite familiar with the rapid transformation of composite pastes to rigid solids, as a routine phenomenon in operative dentistry. But they still lack scientific understanding how and why this happens. Efforts learn scientifically about interaction between light beams resin-composites can significantly promote effective clinical placement restorations. Neglect such stud...
