Twelfth Annual Report for the year ended the 31st March, 1963

This is the twelfth Annual report of the Cumberland River Board on information of its activities and responsibilities on river management in its area between the beginning of April 1962, to the end of March 1963. The report contains 5 main sections on water resources, land drainage, fisheries, pollution, and finally the expenditure and income for the 12 month period. The first area that the report deals with is water resources, which includes information on the completion of gauging stations, abstraction of water and rainfall. The section on land drainage looks at work on improvement schemes, floods and information on maintenance work carried out on rivers including Wampool, Waver, Wiza, Ellen, Cocker, Greta, Marron, Ehen, Keekle, Esk, Bleng, Mite, Annas, Eden, Caldew and Petteril. The fisheries section covers 5 districts of the River Eden, Esk, Derwent, Ellen and South West Cumberland. It includes angling information and a general report for salmon and sea trout, brown trout and freshwater fish. Fish disease and fish hatchery are also covered as well as Byelaws and fisheries protection. The fourth section on pollution covers water quality and information on sewage and trade effluents. The River Boards preceded the Environment Agency which came into existence in 1996.

River Dart Scale Reading Investigation Report on the 1963 Season

This is the second River Dart Scale Reading Investigation Report on the 1963 season by the Devon River Board. The object of this investigation is to examine, by means of scale-reading, the general biology of the salmon population of the River Dart. It reviews the methods used for the collection of scales and examination of the materials. It shows the results of the survey and number of scales studied from each of the various sea-age classes, time of running with distribution of the sea-age groups throughout the season, fish sizes and smolt ages at migration. All are summarized in tables, and figures are alo included plotting weight distributions for each age classes and frequency distributions. The report also remarks the similarity of the results with those for 1962.

River Teign Fisheries Survey 1963

This is the River Teign Fisheries Survey from 1963 by the Devon River Authority. The principal object of the survey is to examine the distribution and relative abundance of salmonid fish in the river system in order to assess the possibility of increasing the salmon population by artificial propagation. A secondary object is to examine the condition of the river downstream of the Rookery Brook confluence, which was affected by the pollution and fish mortality in 1962 to assess the advisability of restocking the length with brown trout. The report contains a brief introduction of the general aspects of the catchment, chemistry, pollution, biology and fisheries in the river, methodology that looks at the selected transects and techniques for sampling and results. In the appendix, it is explained why the Board have decided to proceed with the artificial propagation and the required procedure. Maps with survey sections and fish indices along with tables with size distributions and totals of salmonids found are attached.

Sex ratios of Metapenaeus kutchensis George, George and Rao, 1963 and Parapenaeopsis sculptilis (Heller, 1862) in the Gulf of Kachchh, Western India

Sex ratio data of two species of penaeid prawns Metapenaues kutchensis George, George and Rao, 1963 and Parapenaeopsis sculptilis (Heller, 1862), occurring in the Gulf of Kachchh, were statistically analysed. A preponderance of females was observed in both the species and the ratio of male to female for both years combined for M. kutchensis and P. sculptilis was found to be 1:15 and 1:2.7, respectively. Chi-square analysis revealed significant difference in the sex ratio of the two species.

On the troll line investigations off Cochin during five fishing seasons. Pt. 2. Investigations during 1963-64 season

During this season the investigations were mainly directed towards elucidation of the selective action of trolling lures. Feather jigs, buffalo horn jigs, stainless steel jigs, Japanese whale bone jigs and plastic jigs were selected. Operations were carried out from Fisheries technology No. 5.

Redescription of Balantidium polyvacuolum Li 1963 (Class: Litostomatea) inhabiting the intestines of Xenocyprinae fishes in Hubei, China

Redescription of Balantidium polyvacuolum Li 1963, collected from the hindgut of Xenocypris davidi and Xenocypris argentea, from Niushan Lake Fishery (30A degrees 19' N, 114A degrees 31' E) in Wuhan City, Hubei Province, China in April and June 2007 is presented in this paper to complete Li's description at both light and scanning electronic microscopic levels. The unique body shape of B. polyvacuolum-highly arched dorsal side and flattened ventral surface-as well as its remarkable concave platelet present in the centroventral were well described and compared with other close Balantidium species. Besides, two types of vestibulum shape are observed in our present work, which may suggest the existence of two subspecies or genotype species of these balantidia.

The freeliving nematode genus Parodontophora Timm 1963 (Nematoda : Axonolaimidae) is not exclusively marine: Parodontophora limnophila sp nov from freshwater in China

Parodontophora limnophila sp. nov. is described from Poyang Lake, the largest freshwater lake of China. It is characterized by having an amphid with its posterior end close to the base of the stoma, relatively short cephalic setae, opisthocephalic setae arranged as two subdorsal groups of three longitudinally arranged setae and two single subventral setae, excretory pore at the level of the anterior part of the stoma and renette gland 34-47% of the oesophageal length. To date, the new species is the only Parodontophora species found in freshwater habitats.

Exploring Musical Diversity in the Collaborative Repertoire from 1880 through 1963

It is essential in musical performance not only to convey the unique language of the composers but also to approach each composition from the perspective of its style. During the 20th century, diverse musical idioms co-existed, sometimes mixing or fusing, yet retaining recognizable characteristics and thereby remaining distinctive. This dissertation explores myriad examples from Late Romanticism/Post- Romanticism, Naturalism, Neo-Classicism, Nationalism and Impressionism composed during this unusually rich period. In order to explore a broad range of collaborative repertoire and to deepen my knowledge of the styles and performance practices relating to these pieces, I studied and performed the repertoire with pianist Eunae Baik–Kim, clarinetist Jihoon Chang, and singers Joshua Brown and Young Joo Lee. The first program featured Post-Romantic, Neo-Classic and Impressionist two-piano works composed by Debussy, Rachmaninoff, and Stravinsky. Each of the three composers used their own distinctive harmonies, rhythms, melodic inventions, pedaling and figurations. In all of the works, both piano parts were densely interwoven, having equal importance. Lied and operatic aria was the focus of the second recital. Brahms’ Vier Ernste Gesänge Op. 121, Ravel’s Don Quichotte a Dulcineé and Italian, French and German operatic arias were the examples of Post-Romanticism and Nationalism. The representative composers were Verdi, Massenet, Korngold, Leoncavallo, Ravel and Wagner. Despite the fact that all of the repertoire was written in traditional musical forms, the composers’ unique voices mark each work as belonging to a particular genre. The third recital focused on Post-Romantic and Impressionistic music written for clarinet and piano: the Première Rhapsodie by Debussy, the Sonata by Poulenc and Brahms’ Sonata in F minor Op. 120, No. 1. These works, although profoundly different in style, share elements of simplicity, clarity and elegance as well as technical virtuosity, articulation and profound musical depth. The three recitals which comprise this dissertation project were performed at the University of Maryland Gildenhorn Recital Hall on February 27, 2010, October 25, 2010, and January 31, 2011. The recitals were recorded on compact disc and are archived within the Digital Repository at the University of Maryland (DRUM).

Riesgo de pérdida de nitratos por lixiviación en fertilizaciones nitrogenadas según manejo uniforme y sitio-específico del cultivo de maíz (Zea mays L.)

Cuando los suelos presentan variabilidad edáfica pronunciada a escala de lote y se fertiliza en forma uniforme en base a una dosis promedio de nitrógeno (N), existirán sectores sub-fertilizados y otros sobre-fertilizados que se asocian a un alto riesgo de pérdidas de N por lixiviación. El manejo sitio-específico (MSE) de la fertilización nitrogenada se sustenta en la capacidad de reconocer zonas de manejo para adecuar la aplicación de N a cada unidad reconocida. El objetivo general de esta Tesis fue evaluar la eficacia del MSE en minimizar el contenido de N residual y potencialmente lixiviable, y mejorar la eficiencia en el uso del N del maíz según zonas de manejo. Se determinó el contenido de agua y nitratos del suelo (2-3 m) en tratamientos de fertilización nitrogenada según manejo uniforme (MU) y MSE, previo a la fertilización y a poscosecha del maíz, durante dos años experimentales. La lixiviación de N fue estimada con el modelo NLEAP (Nitrate Leaching and Economic Analysis Package) mediante experimentos de simulación bajo distintos escenarios climáticos. Se observó una reducción del 32 por ciento del N residual en zonas de baja productividad de maíz con MSE de N, respecto del MU, únicamente en el segundo año experimental. Al ponderar el contenido de N residual por la proporción de las zonas de manejo a nivel lote, el MSE logró reducir un 18 por ciento el N residual en promedio en ambos años experimentales. En términos generales, se detectaron diferencias a favor del MSE, respecto del MU, en las eficiencias de uso de agua y N del maíz. Los experimentos de simulación evidenciaron una mayor lixiviación de nitratos con MU que con MSE a nivel lote en todos los escenarios climáticos estudiados del primer año experimental. El MSE de N puede ser considerado como una práctica conservacionista que optimice la eficiencia de uso del agua y N, a la vez de maximizar los rendimientos. Además, puede facilitar la identificación de aquellas áreas dentro del lote con mayor susceptibilidad a las pérdidas de N por lixiviación. La proporción de las zonas de manejo resulta un factor espacial imprescindible para determinar el riesgo potencial de lixiviación de nitratos a nivel lote
