The lateral and vertical integration density of bulk microelectromechanical systems (MEMS) using bonded silicon-on-insulator (BSOI) wafers is significantly enhanced if the handle wafer is used as an electrical redistribution layer. Therefore isolated

This paper presents the vacuum wafer level packaging of in-house manufactured two-dimensional micro- mirrors based on the electrostatic driving principle, fabricated using a bulk technology on bonded-silicon-on-insulator wafers. The so called buried

In the present study the teats of the goat and the sheep were investigated light microscopically. In both species, smooth muscle elements condense towards the streak canal, and abundant arteries occur with thick tunica media and various valve structu

Corpora amylacea are present in all the mammary glands of the investigated animals (ewe, goat, and mares). Generally, they are comparable to the cow regarding to its distribution, frequency, size, morphological structure, and staining properties. Cor

In the present report, the arrangement of the milk-duct system of one quarter of the bovine udder has been investigated using a corrosion preparation. In general, the observations revealed the following remarkable principles of construction: 1. The m

The skin of the mammary gland of the merino sheep was investigated on 5 different areas by light microscopical and morphometrical means. The epidermis is continuously developed in the same manner, in which a stratum lucidum is lacking. It contains re

The purpose of the study was to give a histological picture of the different skin regions of the mammary gland in mares. Special emphasis on the dark coating in the sulcus intermammarius was given. As a result, the dark pigmented udder skin can be su

Generally, the skin of the bovine mammary gland is found to be similar to the skin of the integument. In the epidermis, the stratum lucidum is lacking. A prominent stratum corneum can be observed as well as in the haired areas and in areas without ha
