Complex (psychology)

A complex is a core pattern of emotions, memories, perceptions, and wishes in the personal unconscious organized around a common theme, such as power or status. Primarily a psychoanalytic term, it is found extensively in the works of Carl Jung and Sigmund Freud.

An example of a complex would be as follows: if you had a leg amputated when you were a child, this would influence your life in profound ways, even if you were wonderfully successful in overcoming the handicap. You might have many thoughts, emotions, memories, feelings of inferiority, triumphs, bitterness and determinations centering on that one aspect of your life. If these thoughts troubled you, Jung would say you had a complex about the leg.

Complex existence is widely agreed upon in the area of depth psychology. It assumes the most important factors influencing your personality are deep in the unconscious. They are generally a way of mapping the psyche, and are crucial theoretical items of common reference to be found in therapy. Complexes are believed by Carl Jung and Sigmund Freud to influence the individual's attitude and behavior.

Multiprotein complex

A multiprotein complex (or protein complex) is a group of two or more associated polypeptide chains. The different polypeptide chains may have different functions. This is distinct from a multienzyme polypeptide, in which multiple catalytic domains are found in a single polypeptide chain.

Protein complexes are a form of quaternary structure. Proteins in a protein complex are linked by non-covalent protein–protein interactions, and different protein complexes have different degrees of stability over time. These complexes are a cornerstone of many (if not most) biological processes and together they form various types of molecular machinery that perform a vast array of biological functions. Increasingly, scientists view the cell as composed of modular supramolecular complexes, each of which performs an independent, discrete biological function.

Through proximity, the speed and selectivity of binding interactions between enzymatic complex and substrates can be vastly improved, leading to higher cellular efficiency. Unfortunately, many of the techniques used to break open cells and isolate proteins are inherently disruptive to such large complexes, so it is often difficult to determine the components of a complex. Examples of protein complexes include the proteasome for molecular degradation and most RNA polymerases. In stable complexes, large hydrophobic interfaces between proteins typically bury surface areas larger than 2500 square angstroms.

Propaganda (desktop backgrounds)

PROPAGANDA is a large collection of GPL-licensed seamless desktop backgrounds included in various Linux distributions, and available via free download over the web. While no longer being produced or even officially hosted online, the collection consisted of approximately 15 volumes of largely abstract and surreal art, numbering over 1,000 images in total. Created in GIMP by Bowie J. Poag, the images were meant to attract users to the platform by virtue of the art having been 100% Linux-generated.

The style of the images produced by Poag were unusual in terms of their geometric qualities. Appearing to repeat seamlessly along all four edges, PROPAGANDA images became attractive for use in 3D modeling, and particularly for use as desktop wallpaper, in that limitations in graphics hardware at the time often prevented users from using full screen 24-bit images. Using smaller, tileable images for desktop backgrounds helped keep memory utilization to a minimum, while still allowing early Linux desktops to be visually appealing.

Propaganda (1999 film)

Propaganda is an award-winning 1999 Turkish comedy film written, directed and produced Sinan Çetin. The film, which is a darkly surreal comedy set in a sleepy village in the southeast Turkey in 1948, starred popular comedy actor Kemal Sunal, who died a year later in 2000. It was shown in competition at the 18th Istanbul International Film Festival and the 4th Shanghai International Film Festival, where it won the Golden Goblet, and went on general release across Turkey on January 5, 1999 (1999-01-05).

Production

The film was shot on location in Hatay, Turkey.

Synopsis

Based on a true story set in 1948, customs officer Mehti is faced with the duty of formally setting up the border between Turkey and Syria, dividing his hometown. He is unaware of the pain that will eminently unfold, as families, languages, cultures and lovers are both ripped apart and clash head on in a village once united.
