Prophalangopsis Obscura
''Prophalangopsis obscura'' is an winged insect species found in North India and the Tibetan Plateau. It is one of only a few surviving species in the family Prophalangopsidae. F. Walker described it in 1869 from a single male specimen from India. Liu ''et al'' collected two possible female specimens in 2009. Bioacoustic modeling In 2022, researchers attempted to recreate the call that ''P. obscura'' would make with its legs by using 3D scanning, microscopy Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of micr ..., and a Laser Doppler vibrometer.

North India
North India is a loosely defined region consisting of the northern part of India. The dominant geographical features of North India are the Indo-Gangetic Plain and the Himalayas, which demarcate the region from the Tibetan Plateau and Central Asia. The term North India has varying definitions. The Ministry of Home Affairs in its Northern Zonal Council Administrative division included the states of Haryana, Himachal Pradesh, Punjab and Rajasthan and Union Territories of Chandigarh, Delhi, Jammu and Kashmir and Ladakh. The Ministry of Culture in its ''North Culture Zone'' includes the state of Uttarakhand but excludes Delhi whereas the Geological Survey of India includes Uttar Pradesh and Delhi but excludes Rajasthan and Chandigarh. Other states sometimes included are Bihar, Gujarat, Jharkhand, Madhya Pradesh and West Bengal. North India has been the historical centre of the Mughal Empire, the Delhi Sultanate and the British Indian Empire. It has a diverse culture, and includ ...

Tibetan Plateau
The Tibetan Plateau (, also known as the Qinghai–Tibet Plateau or the Qing–Zang Plateau () or as the Himalayan Plateau in India, is a vast elevated plateau located at the intersection of Central, South and East Asia covering most of the Tibet Autonomous Region, most of Qinghai, western half of Sichuan, Southern Gansu provinces in Western China, southern Xinjiang, Bhutan, the Indian regions of Ladakh and Lahaul and Spiti (Himachal Pradesh) as well as Gilgit-Baltistan in Pakistan, northwestern Nepal, eastern Tajikistan and southern Kyrgyzstan. It stretches approximately north to south and east to west. It is the world's highest and largest plateau above sea level, with an area of (about five times the size of Metropolitan France). With an average elevation exceeding and being surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2, the Tibetan Plateau is often referred to as "the Roof of the World". The Tibetan Plateau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prophalangopsidae
The family Prophalangopsidae are insects belonging to the order Orthoptera. They are the only extant members of the superfamily Hagloidea. There is only one extant genus in North America, where they are known as grigs, four genera in Asia, and many extinct genera (see below). The closest living relatives to the Prophalangopsidae are the family Tettigoniidae (katydids or bush-crickets), but the evolutionary split occurred more than 230 million years ago in the Permian. The female of the species consumes the wings of the male during mating. Haglidae is often used as a synonym of the family, but is used to refer to a distinct grouping of extinct hagloids by paleontologists. Subfamilies and genera The Orthoptera Species File lists the following: Archibald, Gu, and Mathewes (2022) removed the genera †'' Albertoilus'' and †'' Palaeorehnia'' from the family, moving them to a newly revised † Palaeorehniidae which they considered unplaced as to superfamily. * Cyphoderrinae Go ...

Hindustan
''Hindūstān'' ( , from '' Hindū'' and ''-stān''), also sometimes spelt as Hindōstān ( ''Indo-land''), along with its shortened form ''Hind'' (), is the Persian-language name for the Indian subcontinent that later became commonly used by its inhabitants in the Hindi–Urdu language. Hindustan was the Persian word for ''India'', but when introduced to the subjects under Persianate rule, the subsequent culture which resulted from these events gave it another specific meaning that of the cultural region between the river Sutlej (end of Northwestern India) and the city Varanasi (start of Eastern India). As the area where Ganga-Jamuni Tehzeeb and the Hindustani language traces its origins, it corresponds to the plains where the river Yamuna flows or the regions/states encompassing Haryana, Delhi, Harit Pradesh, and Awadh. Other toponyms for the subcontinent include ''Jambudvīpa'' and '' Bharata Khanda''. Since the Partition of India in 1947, although limitedly, ''Hindusta ...

3D Scanning
3D scanning is the process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects. For example, industrial computed tomography scanning, structured-light 3D scanners, LiDAR and Time Of Flight 3D Scanners can be used to construct digital 3D models, without destructive testing. Collected 3D data is useful for a wide variety of applications. These devices are used extensively by the entertainment industry in the production of movies and video games, including virtual reality. Other common applications of this technology include augmented reality, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microscopy
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy. Optical microscopy and electron microscopy involve the diffraction, reflection, or refraction of electromagnetic radiation/electron beams interacting with the specimen, and the collection of the scattered radiation or another signal in order to create an image. This process may be carried out by wide-field irradiation of the sample (for example standard light microscopy and transmission electron microscopy) or by scanning a fine beam over the sample (for example confocal laser scanning microscopy and scanning electron microscopy). Scanning probe microscopy involves the interaction of a scanning probe with the surface of the objec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Doppler Vibrometer
A laser Doppler vibrometer (LDV) is a scientific instrument that is used to make non-contact vibration measurements of a surface. The laser beam from the LDV is directed at the surface of interest, and the vibration amplitude and frequency are extracted from the Doppler shift of the reflected laser beam frequency due to the motion of the surface. The output of an LDV is generally a continuous analog voltage that is directly proportional to the target velocity component along the direction of the laser beam. Some advantages of an LDV over similar measurement devices such as an accelerometer are that the LDV can be directed at targets that are difficult to access, or that may be too small or too hot to attach a physical transducer. Also, the LDV makes the vibration measurement without mass-loading the target, which is especially important for MEMS devices. Principles of operation A vibrometer is generally a two beam laser interferometer that measures the frequency (or phase) differe ...

Ensifera
Ensifera is a suborder of insects that includes the various types of crickets and their allies including: true crickets, camel crickets, bush crickets or katydids, grigs, weta and Cooloola monsters. This and the suborder Caelifera (grasshoppers and their allies) make up the order Orthoptera. Ensifera is believed to be a more ancient group than Caelifera, with its origins in the Carboniferous period, the split having occurred at the end of the Permian period. Unlike the Caelifera, the Ensifera contain numerous members that are partially carnivorous, feeding on other insects, as well as plants. ''Ensifer'' is Latin for "sword bearer", and refers to the typically elongated and blade-like ovipositor of the females. Characteristics Characteristics shared by the two orthopteran suborders, Caelifera and Ensifera, are the mouthparts adapted for biting and chewing, the modified prothorax, the hind legs modified for jumping, the wing shape and venation, and the sound-producing stridu ...
