The Kramis fan offshore western Algeria: the role of sediment waves in turbiditic levee growth
Provedor de dados: 5
Autores: Babonneau, Nathalie; Cattaneo, Antonio; Savoye, Bruno; Barjavel, Guy; Deverchere, Jacques; Yelles, Karim.
The Kramis deep-sea fan extends over 45 km at the base of the western Algerian continental slope between 2000 and 2550 m water depth and covers an area of approximately 1200 km2. The Kramis Fan was initiated after Messinian time, evolved during the Plio-Quaternary, and, is still active, as proved by submarine cable breaks during the 1954 Orléansville earthquake. The Kramis Fan is fed by two perpendicular canyons: the Kramis Canyon and the Khadra Canyon, merging in a single E–W-oriented channel confined at the foot of the slope. It is strongly asymmetric with a super-developed levee on the right-hand side of the channel, the Kramis Ridge.  Based on recent multibeam, side-scan sonar, and sediment core data (Maradja, 2003 and 2005, Prisma, 2004, and Prisme,...

CHAPA, BEEF COW/CALF HEALTH AND PRODUCTIVITY AUDIT, PART III: BEEF COW/CALF HEALTH MANAGEMENT
Provedor de dados: 31
Autores: Dargatz,   David.
As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part III: Beef Cow/Calf Health &amp; Health Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 4 and February 28, 1993. These 18 states represented 70 percent of the U.S. beef cow inventory. Participating producers had five or more beef cows or beef replacement heifers and fifty percent or more of their 1992 calf crop...

DAIRY HERD MANAGEMENT PRACTICES FOCUSING ON PREWEANED HEIFERS
Provedor de dados: 31
Autores: Ott,   Stephen L.
The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992 with the assistance of 1,811 producers from 28 states. Producers included in the study each had herds of 30 or more milk cows, representing 78 percent of the milk cows in the U.S. The average total of cattle and calves on each operation was 169.4. The main breed on 94.9% of operations was Holstein. Slightly over 46 percent of operations stated reproductive problems as the cause of low milk production of cows culled from the herd. Newborn calves were separated from their mothers before nursing on 28.0 percent of operations and less than 12 hours after birth on 39.6 percent of operations. On 64.0...

CHAPA, BEEF COW/CALF HEALTH AND PRODUCTIVITY AUDIT, PART V: QUALITY ASSURANCE PROFILE
Provedor de dados: 31
Autores: Dargatz,   David.
As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. The National Agricultural Statistics Service (NASS) collaborated with USDA:APHIS:VS to select a producer sample that was statistically designed to provide inferences about the nation's cow/calf population. Data for Part V: Quality Assurance Profile were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 1 and January 31, 1994. The average...
