Adaptive behavior

Adaptive behavior is a type of behavior that is used to adjust to another type of behavior or situation. This is often characterized as a kind of behavior that allows an individual to change a nonconstructive or disruptive behavior to something more constructive. These behaviors are most often social or personal behaviors. For example a constant repetitive action could be re-focused on something that creates or builds something. In other words the behavior can be adapted to something else.

In contrast, maladaptive behavior is a type of behavior that is often used to reduce one's anxiety, but the result is dysfunctional and non-productive. For example, avoiding situations because you have unrealistic fears may initially reduce your anxiety, but it is non-productive in alleviating the actual problem in the long term. Maladaptive behavior is frequently used as an indicator of abnormality or mental dysfunction, since its assessment is relatively free from subjectivity. However, many behaviors considered moral can be apparently maladaptive, such as dissent or abstinence.

Red Orchestra 2: Heroes of Stalingrad

Red Orchestra 2: Heroes of Stalingrad is a World War II-themed tactical first-person shooter video game developed and published by Tripwire Interactive. It is a sequel to Red Orchestra: Ostfront 41-45. The title focuses heavily on the Battle of Stalingrad. The game was released on 13 September 2011. The developers have stated that the game is a Windows exclusive and have no plans to bring it to consoles. The game contains many new features, including a new first-person cover system combined with blind firing, first person collision detection, as well as an entirely new system of statistics tracking and player development.

Gameplay

Red Orchestra 2 is a realistic first-person shooter. Guns behave realistically, with bullet drop and spin taken into account. The game also takes away many of the elements of a traditional HUD, like an ammo counter, forcing players to remember, or manually check, the approximate number of rounds that are left in the gun's magazine. When reloading a weapon, the character checks the weight of the new magazine and determines if it is heavy (full or close to full) or light (empty or close to empty). The game's first-person cover system allows players to hide behind all objects in the world to avoid gunfire. While in cover, players can peek out to take more accurate shots or fire blindly. However, the shape, size and, composition of the object changes its effectiveness at protecting the player. Smaller objects may not cover the player's entire body, and some may not stop bullets. Health does not regenerate over time or by use of medical equipment, but non-fatal wounds must still be bandaged so no more health is lost through blood loss.

Autodesk Revit

Autodesk Revit is building information modeling software for architects, structural engineers, MEP engineers, designers and contractors. It allows users to design a building and structure and its components in 3D, annotate the model with 2D drafting elements, and access building information from the building model's database. Revit is 4D BIM capable with tools to plan and track various stages in the building's lifecycle, from concept to construction and later demolition.

History

Charles River Software was founded in Newton, Massachusetts, on October 31, 1997, by Leonid Raiz and Irwin Jungreis, key developers of PTC's Pro/Engineer software for mechanical design, with the intent of bringing the power of parametric modeling to the building industry (PTC had previously tried and failed to market its recently acquired Reflex software to the construction sector). With funding from venture capitalists Atlas Venture and North Bridge Venture Partners, Raiz and Jungreis hired several software developers and architects and began developing Revit in C++ on the Microsoft Windows platform. In 1999 they hired Dave Lemont as CEO and recruited board members Jon Hirschtick, founder of SolidWorks, and Arol Wolford, founder of CMD Group.

Immune system

The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system, or humoral immunity versus cell-mediated immunity. In humans, the blood–brain barrier, blood–cerebrospinal fluid barrier, and similar fluid–brain barriers separate the peripheral immune system from the neuroimmune system which protects the brain.

Pathogens can rapidly evolve and adapt, and thereby avoid detection and neutralization by the immune system; however, multiple defense mechanisms have also evolved to recognize and neutralize pathogens. Even simple unicellular organisms such as bacteria possess a rudimentary immune system, in the form of enzymes that protect against bacteriophage infections. Other basic immune mechanisms evolved in ancient eukaryotes and remain in their modern descendants, such as plants and insects. These mechanisms include phagocytosis, antimicrobial peptides called defensins, and the complement system. Jawed vertebrates, including humans, have even more sophisticated defense mechanisms, including the ability to adapt over time to recognize specific pathogens more efficiently. Adaptive (or acquired) immunity creates immunological memory after an initial response to a specific pathogen, leading to an enhanced response to subsequent encounters with that same pathogen. This process of acquired immunity is the basis of vaccination.
