Due to the superior thermal, mechanical and chemical properties of ceramics, metallized ceramics are widely used as circuit carriers and interconnect devices wherever standard polymer-based circuit boards come to their limits. 2D metallization represents the current state-of-the-art. The metallization of 3D shaped ceramics cannot be achieved with standard metallization techniques and is still a field of research. In this study laser induced direct metallization (LDM) is applied, where a pulsed laser is used to locally activate the surface of a Cr2O3 doped ZTA ceramic. Subsequently a selective electroless copper plating on the laser irradiated areas is performed. Laser power, pulse repetition frequency, pulse overlap and the amount of surpasses were varied systematically in order to determine the parametric sensitivity of the ablation and metallization behavior for pulsed infrared laser structuring. It was found that ablation is necessary for the metallization and the peak fluence is the governing factor for the ablation and metallization process. It was further shown, that the ablation can be well predicted with an accumulated fluence which includes the pulse overlap. 3D ceramic substrates were successfully metallized applying an optimized set of laser parameters.

Native Mexican turkeys (Meleagris gallopavo gallopavo) are an important genetic resource in family-based production systems exposed to marked regional and seasonal environmental variation. This study evaluated the effects of environmental gradients shape diet composition and hematological responses of native Mexican turkeys raised in family production systems. Fifty approximately six-month-old males were evaluated in a 5 × 2 factorial design including five physiographic regions and two seasons (rainy and dry). Crop content composition, estimated dietary nutrient composition, body weight, and hematological profile were analyzed using multivariate analysis of variance, principal component analysis (PCA), and multiple regression. Grains and energy-rich by-products predominated in the diet (58.2–76.2%), whereas the dry season increased dry plant fragments and crude fiber while reducing crude protein from 17.5 to 14.3% (p < 0.001). Body weight was greatest in the Neovolcanic Axis (5.20 kg) and lowest on the Coast (4.35 kg) (p < 0.001). Erythrocyte-related variables were higher in temperate, high-altitude regions, whereas leukocyte-related variables predominated in warmer regions (p < 0.05). PCA explained 71.3% of the total variation, identifying nutritional–productive and immunological–adaptive components. Physiographic region was the main determinant of diet composition and hematological responses, whereas the dry season intensified nutritional constraints and their effects on physiological adaptation.
