The Father of the House in the current (2019) Parliament is Sir Peter Bottomley, who was first elected to the House in a by-election in 1975. Under Standing Order No 1, as long as the Father of the House is not a Minister, he takes the Chair when the House elects a Speaker. He has no other formal duties. There is evidence of the title having been used in the 18th century. However, the origin of the term is not clear and it is likely that different qualifications were used in the past. The Father of the House is not necessarily the oldest Member. -

History of Calculus is part of the history of mathematics focused on limits, functions, derivatives, integrals, and infinite series. The subject, known Background historically as infinitesimal calculus, Theories/sociology constitutes a major part of modern Historiography mathematics education. It has two major Pseudoscience branches, differential calculus and By era integral calculus, which are related by In early cultures in Classical Antiquity the fundamental theorem of calculus. In the Middle Ages Calculus is the study of change, in the In the Renaissance same way that geometry is the study of Scientific Revolution shape and algebra is the study of By topic operations and their application to Natural sciences solving equations.

In both are too low and that the largest of these insects (wingspan of 70 cm or drawings, the abdomen is similar in diameter to the thorax, unlike more) would have had a mass of 100–150 g, several times greater the structure of most modern dragonflies, which have much more – – than previously thought. Here, the power needed to generate lift and slender abdomens. This large size and consequently high mass fly at the speeds typical of modern large dragonflies is examined has attracted attention for over a hundred years as there are no extant together with the metabolic rate and subsequent heat generated by insects of this size and their physiology in terms of power generation the thoracic muscles. This evaluation agrees with previous work and thermoregulation is not understood. This Commentary suggesting that the larger specimens would rapidly overheat in the examines the questions of mass, power generation to fly and high ambient temperatures assumed in the Permian. -

PIR/PER) for the State Route 86 / Avenue 50 New Interchange Project, City of Coachella, Riverside County, California E-FIS 0801-000144 (EA 08-0C970
Combined Paleontological Identification Report / Paleontological Evaluation Report (PIR/PER) for the State Route 86 / Avenue 50 New Interchange Project, City of Coachella, Riverside County, California E-FIS 0801-000144 (EA 08-0C970) Submitted to: Kurt Heidelberg, Branch Chief Environmental Studies D California Department of Transportation, District 8 464 West 4th Street, 6th Floor, MS 825 San Bernardino, California 92401-1400 March 2018 EXECUTIVE SUMMARY The City of Coachella (City), in cooperation with the California Department of Transportation (Caltrans) District 8 and Coachella Valley Association of Governments (CVAG), proposes the construction of a new interchange at State Route 86 (SR-86) and Avenue 50 in the City of Coachella, Riverside County, California. The SR-86 /Avenue 50 New Interchange Project (Project) consists of converting a portion of SR-86 from an existing expressway to a freeway with a new overcrossing structure and access ramps. In addition, the proposed Project includes the realignment and widening of Avenue 50 and the realignment of portions of Tyler Street on both the east and west sides of SR-86. Finally, the Project would construct a new bridge over the Coachella Valley Stormwater Channel (CVSC) to replace the existing low water crossing. At the request of TranSystems, Applied EarthWorks, Inc. (Æ) performed a paleontological resource assessment in support of the proposed Project. The study consisted of a search of museum collections records maintained by the Natural History Museum of Los Angeles County, a comprehensive literature and geologic map review, a field reconnaissance survey, and preparation of this combined Paleontological Identification Report (PIR) / Paleontological Evaluation Report (PER). -

A Large Hadrosaurid Dinosaur from Presa San Antonio, Cerro Del Pueblo Formation, Coahuila, Mexico
A large hadrosaurid dinosaur from Presa San Antonio, Cerro del Pueblo Formation, Coahuila, Mexico ROGELIO ANTONIO REYNA-HERNÁNDEZ, HÉCTOR E. RIVERA-SYLVA, LUIS E. SILVA-MARTÍNEZ, and JOSÉ RUBÉN GUZMAN-GUTIÉRREZ Reyna-Hernández, R.A., Rivera-Sylva, H.E., Silva-Martínez, L.E., and Guzman-Gutiérrez, J.R. 2021. A large hadro- saurid dinosaur from Presa San Antonio, Cerro del Pueblo Formation, Coahuila, Mexico. Acta Palae onto logica Polonica 66 (Supplement to x): xxx–xxx. New hadrosaurid postcranial material is reported, collected near Presa San Antonio, Parras de la Fuente municipality, Coahuila, Mexico, in a sedimentary sequence belonging to the upper Campanian of the Cerro del Pueblo Formation, in the Parras Basin. The skeletal remains include partial elements from the pelvic girdle (left ilium, right pubis, ischium, and incomplete sacrum), a distal end of a left femur, almost complete right and left tibiae, right metatarsals II and IV, cervical and caudal vertebrae. Also, partially complete forelimb elements are present, which are still under preparation. The pubis shows characters of the Lambeosaurinae morphotypes, but the lack of cranial elements does not allow us to directly differentiate this specimen from the already described hadrosaurid taxa from the studied area, such as Velafrons coahuilensis, Latirhinus uitstlani, and Kritosaurus navajovius. This specimen, referred as Lambeosaurinae indet., adds to the fossil record of the hadrosaurids in southern Laramidia during the Campanian. Key words: Dinosauria, Hadrosauridae, Lambeosaurinae, Cretaceous, Campanian, Mexico. Rogelio Antonio Reyna-Hernández [[email protected]], Luis E.
