Standard histories of Australian education and educational administration during the years 1900-1970 largely have ignored the influences of scientific management and eugenics on teacher selection and preparation. Selleck, Connell, Kamagra Jelly Australia Hyams and Cleverly and Lawry are examples of historians who have attempted to analyse Australian 20th-century educational history without any reference to eugenics or scientific management. https://en.wikipedia.org/wiki/Sildenafil This paper analyses the connection between the principles and methods of scientific management and eugenics. In the United States, Ellwood Cubberley was an enthusiastic eugenicist who helped popularise the application of scientific management to the administration of schools. He directly influenced the work of the Australian educators Kenneth Cunningham and Harold Wyndham,… https://www.kamagraaustralia.net both of whom were influential in arguing for a ‘scientific’ process of teacher selection and preparation. Teachers were required to meet prescribed standards of ‘fitness’ and to fit preconceived criteria of suitability as agents of racial and national efficiency. By the 1950s, with the advent of residential teachers’ colleges, Cheap Kamagra Paypal State Departments of Education were in a unique position to ensure that student teachers entered the state teaching service suitably equipped with attributes of ‘fitness’.

Optimization of the cross-sectional area distribution of a high-speed train nose is conducted for various nose lengths in order to minimize the micro-pressure wave intensity at a tunnel exit. Kamagra Gel Australia To this end, an inviscid compressible flow solver is adopted with an axi-symmetric patched grid system. To improve the shape of the train nose, multi-step design optimization is performed using the Broyden–Fletcher–Goldfarb–Shanno (BFGS) algorithm with a response surface model. The optimization reveals that the optimal nose shapes differ for different nose lengths. For a short nose, the shape has an extremely blunt front end, and the cross-sectional area decreases in the middle section. https://www.kamagraaustralia.net As the nose length increases, the nose shape flattens around the middle section. These optimal shapes divide one… large compression wave into two small waves by causing a strong expansion effect between the front and rear ends. As a result, through the nose shape optimization, the intensity of the micro-pressure wave is reduced by 18–27% compared to a parabolic nose, which has a minimum variation of the cross-sectional area change. Kamagraaustralia The optimized distribution of the cross-sectional area can be used as a guideline for the design of three-dimensional nose shapes of high-speed trains, further improving their aerodynamic performance.

Juvenile idiopathic arthritis (JIA) has an incidence that ranges from 1 to 22 per 100,000 children worldwide, with involvement of the temporomandibular joint (TMJ) in 17–87% of patients. Kamagra Australia Intraarticular corticosteroid injections are beneficial in the local treatment of JIA and of other types of arthritis. To describe and assess the accuracy of an US-guided technique for visualization of needle placement within the TMJ in children. Between January 2000 and November 2007, 180 TMJ injections were performed during 116 encounters in 83 children with arthritis (71 girls, 12 boys; mean age 12.0 years). Access was obtained under sterile conditions using US guidance (linear 15-MHz or curvilinear 8-MHz transducers) in a coronal plane, and confirmed with CT. To minimize radiation, https://www.kamagraaustralia.net a limited focused… CT protocol was developed. A bilateral injection was performed in 65 encounters (57%). Twenty-three children had repeat TMJ injections. All injections were performed using US guidance. CT confirmation was used in 127/180 TMJs (70%). In those confirmed with CT, the needle tip was intra-articular in 91% of cases. Triamcinolone hexacetonide was used in 92% of injections and triamcinolone acetonide in 8%. Cheap Kamagra Australia One major complication was encountered (skin atrophy at the injection site). In our experience, TMJ injections using sonographic guidance is a safe, effective and accurate procedure.
