The biomechanics of the hip joint using new diagnostic aspects in the field of hip joint dysplasia. Constructive criticism of hip dysplasia diagnosis and present marketable breeding methods with an outlook on future perspectives and possibilities. Part I

In absence of basic canine hip biomechanics, a specific, consequent three dimensional concept to evaluate the coxofemoral joint was developed for the dog. With the help of a new method to radiologically demonstrate the hip in a physiological standing position several new clinically relevant aspects could be further investigated. For example the breed specific anatomical differences in the hip, and dynamics and the background on "iatrogenic luxations" in HD diagnostics could be shown. The caudal luxation and the growth abnormalities of the hip and their consequences on the whole leg (antetorsion syndrome) as a consequence of inadequate breeding could be demonstrated.

Planning of a make-to-order production process in the printing industry

Offset printing is a common method to produce large amounts of printed matter. We consider a real-world offset printing process that is used to imprint customer-specific designs on napkin pouches. The production equipment used gives rise to various technological constraints. The planning problem consists of allocating designs to printing-plate slots such that the given customer demand for each design is fulfilled, all technological and organizational constraints are met and the total overproduction and setup costs are minimized. We formulate this planning problem as a mixed-binary linear program, and we develop a multi-pass matching-based savings heuristic. We report computational results for a set of problem instances devised from real-world data.

Bacterial production in the eastern Mediteranean Sea in October 2008 during SES_GR2

The HCMR_SES_LAGRANGIAN_GR2_ MICROBIAL PARAMETERS dataset is based on samples collected in the framework of the project SESAME, in the North Aegean Sea during October 2008. The objectives were to measure the standing stocks and calculate the production of the microbial compartment of the food web, describe the vertical distribution pattern and characterize its structure and function through the water column as influenced by the BSW. Bacterial production was estimated by the 3H-leucine method (Kirchman et al. 1986, Kirchman 1993). At each depth, duplicate samples and a control were incubated with 20 nM L-[4,5 3H]-leucine. Samples were incubated in the dark, at in situ temperature.

Bacterial production in the eastern Mediterranean Sea in March and April 2008 during SES_GR1

The dataset is based on samples collected in the framework of the project SESAME, in the Ionian, Libyan and Aegean Sea during March- April 2008. The objectives were to measure the standing stocks and calculate the production of the microbial compartment of the food web, describe the vertical distribution pattern and characterize its structure and function through the water column. Bacterial production was estimated by the 3H-leucine method (Kirchman et al. 1986, Kirchman 1993). At each depth, duplicate samples and a control were incubated with 20 nM L-[4,5 3H]-leucine. Samples were incubated in the dark, at in situ temperature.

Bacterial abundance in the Strait of Magellan

Bacterial abundance, bacterial secondary production (BSP) and potential ectoproteolytic activity (PEA) were measured at 6 stations along the Strait of Magellan, South America, toward the end of summer 1995. Because of hydrological and climatic factors, 3 main areas could be identified in which the bacterial component displayed specific characteristics. In the Pacific Ocean side, subjected to freshwater inputs from rainfalls and melting of glaciers, the bacterial activities showed the highest values (BSP: 228.2 ng C/l h; PEA: 12.2 nmol/l h). The bacterial biomass was greater than the phytoplanktonic biomass, probably due to organic inputs from land stimulating the bacterial growth. The central part of the Strait demonstrated the lowest values (BSP: 32.6 ng C/l h, PEA: 4.6 nmol/l h), although the ratio of bacterial biomass to phytoplanktonic biomass was greater than 1. In the third area, the Atlantic Ocean opening, subjected to strong tidal currents, BSP and PEA displayed high values, 80 to 88.7 ng C/l h and 11.7 nmol/l h respectively. Nevertheless, the ratio of bacterial to phytoplanktonic biomass was less than 1, like in eutrophic areas. On the other hand, no impact of the tide was noted on bacterial parameters. Considering all samples measured in the 0 to 50 m layer, although BSP and PEA were positively correlated with bacterial abundance, the PEA to BSP ratio was negatively correlated with the bacterial biomass (r = -0.72, p < 0.001, n = 22). This ratio could be an indicator of trophic conditions in the 3 subsystems of the Strait.
