The besra (Accipiter virgatus), also called the besra sparrowhawk, is a bird of prey in the family Accipitridae. The besra is a widespread resident breeder in dense forests throughout southern Asia, ranging from the Indian subcontinent eastwards across Southeast Asia and into East Asia. It nests in trees, building a new nest each year. It lays 2 to 5 eggs. This bird is a medium-sized raptor (29 to 36 cm) with short broad wings and a long tail, both adaptations to fast maneuvering through dense vegetation. The normal flight of this species is a characteristic "flap–flap–glide". This species is like a darker version of the widespread shikra with darker upperparts, strongly barred underwing, broader gular stripe and thin long legs and toes. The adult male besra has dark blue-grey upperparts, and is white, barred reddish brown below. The larger female is browner above than the male. The juvenile is dark brown above and white, barred with brown below. In all plumages have 3-4 equally sized dark bands on uppertail. In winter, the besra will emerge into more open woodland including savannah and cultivation...

TRIZ (; Russian: теория решения изобретательских задач, teoriya resheniya izobretatelskikh zadach, literally theory of inventive problem solving) is an approach that combines an organized and systematic method for problem solving with analysis and forecasting techniques derived from the study of patterns of invention in the global patent literature. The development and improvement of products and technologies in accordance with TRIZ are guided by the objective laws of technical systems evolution, forming the basis for TRIZ problem solving tools and methods. It was developed by Genrich Altshuller, a Soviet inventor, and science-fiction author, along with his colleagues, starting in 1946. In English the name is typically rendered as the theory of inventive problem solving, and occasionally goes by the English acronym TIPS.Following Altshuller's insight, the theory developed on a foundation of extensive research covering hundreds of thousands of inventions across many different fields to produce a theory...

Kakadu National Park is a protected area in the Northern Territory of Australia, 171 km (106 mi) southeast of Darwin. It is a World Heritage Site. Kakadu is also gazetted as a locality, covering the same area as the national park, with 313 people recorded living there in the 2016 Australian census. Kakadu National Park is located within the Alligator Rivers Region of the Northern Territory, covering an area of 19,804 km2 (7,646 sq mi), extending nearly 200 kilometres (124 mi) from north to south and over 100 kilometres (62 mi) from east to west. It is roughly the size of Wales or one-third the size of Tasmania, and is the second-largest national park in Australia, after the Munga-Thirri–Simpson Desert National Park. Most of the region is owned by the Aboriginal traditional owners, who have occupied the land for around 60,000 years and, today, manage the park jointly with Parks Australia. It is highly ecologically and biologically diverse; hosting a wide range of habitats and flora and fauna, Kakadu is fully protected by the EPBC Act. It also includes a rich heritage of Aboriginal rock art, including highly significant...
