Christian Lantz and Salem YMCA
No full textThis lantern slide shows two images: the Salem YMCA and Christian Lantz, who graduated in 1894 from the International YMCA Training School, now Springfield College.Born in Bryn Mawr, Pennsylvania, Christian Lantz was a civic leader and father of the playground system in America. He served as general secretary of the Greenpoint YMCA in New York (1894-1899) and the Salem YMCA in Massachusetts (1900-1935). In 1907, he solicited funds to set up two playgrounds. After two years, he persuaded the city of Salem to take over the operation of the playgrounds. He founded the Salem Philharmonics and in 1914 was chairman of the Salem fire relief committee. He was drafted by the National Red Cross in 1917 to set up rehabilitation work in Halifax, Nova Scotia, following an explosion of a munitions ship. During World War I, President Wilson drafted Lantz to organize the war branch of the merchant marine and reorganize the United States shipping board. He was founder of the Pioneer Viollage in Salem, which was prepared for the 1939 tercentenary celebration of the state as a reproduction of the original 1630 Salem colony. Lantz was a member of the Salem park commission, trustee of the Salem YMCA, trustee of Salem Hospital, member of the Salem Rotary Club, and vice-president of the Salem Savings Bank. On September 19, 1955, the Salem YMCA broke ground on a swimming pool named in his honor. He died on October 16, 1955. The Salem YMCA was established in the 1850s, and the historic building pictured here was built in 1898. It has served as a museum, professional building, and civic building. It was added to the National Register of Historic Places in 1983.Text on border reads, "Christian Lantz '94, Gen Sec, YMCA, Salem, Mass.
Apron and cutoff wall scour protection for piano key weirs
No full textPiano key (PK) weirs are used in a variety of flow control structure applications, including spillway crests and open channel diversion structures. However, to the best of authors’ knowledge, structure-specific design guidance for scour mitigation is still needed. To fill this gap of knowledge, a systematic experimental campaign was conducted by testing different configurations of horizontal aprons with a cutoff wall. Protection structures were located at the toe of the PK weir. Namely, experiments were performed at large-scale to assess the effect of three apron lengths on downstream scour hole geometry under different hydraulic conditions. It was observed that a horizontal apron deflects the plunging jets originating from the PK weir, thus significantly reducing scour. Experimental evidence allowed corroboration that significant scour depth reduction occurs for an apron length 1.5 times the weir height, with longer aprons found to provide marginal benefits. Finally, also provided herein are tools to estimate the main scour characteristics and help practitioners in optimizing apron design
Flood infrastructure: Localized scour at piano key weirs
No full textHistoric growth in the US coupled with observed hydrologic changes have created an increased demand for sustainable flood protection. One approach to passing floodwaters is nonlinear weirs such as labyrinth and Piano Key weirs (PK weirs). Although they are being designed in greater frequency, one area lacking in information or design guidance is the prediction of local scour at these weirs. Without proper protection, downstream local scour can compromise the weirs' foundation. Therefore, a large-scale laboratory study has been undertaken to investigate the effect of different lengths of downstream aprons on the scour mechanism at the foundation of a PK weir. This paper presents a preliminary analysis of equilibrium scour morphology under different flow conditions and with non-cohesive bed material. Instrumentation included 3D cameras and ultrasonic sensors to capture scour features and measure dynamic water surface elevations, respectively

Nowe spojrzenie na planowanie architektury mieszkaniowej w afryce subsaharyjskiej
No full textThe author shares his reflections on state of art in housing and urban planning, deficiencies, expectations and possibilities in the Sahel region of Africa. He notices, that the housing problem in Africa is one of the challenges, which should be solved in order to recover life dignity of African people and secure their rights to traditional family life in acceptable conditions. The paper describes the studies on the typical dispersed urban structures and the need to foster this type of settlement structure and proposals of introduction of new on light steel frame housing system in the area of Sahel, combining the traditional way of building houses with modern technology. The particularly analysed case, is the housing problem in the Republic of Chad. The author presents the basic discussion on this topic and his architectural proposals. Unfortunately, the gap between the needs and the financial feasibility of housing construction in this area, makes this project already at the starting point extremely difficult to be realized without external subventions.Problem mieszkaniowy w Afryce jest jednym z wyzwań, które należy rozwiązać, aby Afrykanie mogli odzyskać godność życiową i zabezpieczyć swoje prawa do tradycyjnego życia rodzinnego w akceptowalnych warunkach. W artykule opisano badania nad typowymi rozproszonymi strukturami miejskimi i potrzebą wspierania tego typu struktur osadniczych oraz propozycji wprowadzenia nowego systemu konstrukcji domów, opartym na lekkim szkielecie stalowym, łączącym tradycyjny sposób budowania domów z nowoczesną technologią. Przypadkiem szczególnie analizowanym jest problem mieszkaniowy w Republice Czadu. Autor przedstawia podstawową dyskusję na ten temat i swoje propozycje architektoniczne. Niestety luka między potrzebami mieszkaniowymi w Czadzie a finansową wykonalnością budownictwa mieszkaniowego w tym obszarze sprawia, że projekt ten, już w punkcie wyjścia, jest niezwykle trudny do realizacji bez uzyskania zewnętrznych dotacji
Evolution of local scour downstream of Type A PK weir in non-cohesive sediments
No full textA large-scale piano key weir laboratory study was conducted to investigate the evolution of the scour process occurring in the downstream basin for two non-cohesive granular bed materials, including the analysis of scour-hole geometry and patterns at equilibrium. It was observed that hydraulic conditions, particularly tailwater level, significantly affect the scour mechanisms and equilibrium morphology, eventually resulting in scour depths that exceeded the weir height. Unprecedented insights on the scour dynamics are also provided, along with tools to estimate the time evolution and maximum scour depth, its location in the streamwise direction, and the maximum scour length
