The Lohmann Brown is a brown variety of chicken, specifically bred for egg-laying purposes. It is a crossbred line [ 1 ] and is selectively bred from lines of the Rhode Island breed. [ 2 ] They start to lay eggs at about 19 weeks and produce up to 320 eggs up to an age of 72 weeks (one year production).
Illustration of thirty-nine varieties of chicken (and one Guinea Fowl) . There are hundreds of chicken breeds in existence. [1] Domesticated for thousands of years, distinguishable breeds of chicken have been present since the combined factors of geographical isolation and selection for desired characteristics created regional types with distinct physical and behavioral traits passed on to ...
The German company Lohmann is one of the first to have integrated this concept on a large scale, as part of its collaboration with the agricultural association Déméter. [ 47 ] It produced its own poultry by crossing lines presenting the sought-after characteristics, [ 48 ] which is a way to solve the problem of killing male chicks.
In the IEEE 802 reference model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer (layer 2) of the seven-layer OSI model. The LLC sublayer acts as an interface between the medium access control (MAC) sublayer and the network layer.
Each of these layers incorporates plans for different time horizons, i.e. the business planning layer determines the planning that the operator must perform to ensure that the network will perform as required for its intended life-span. The Operations and Maintenance layer, however, examines how the network will run on a day-to-day basis.

The HMS Media Access Control (MAC) Layer Specification describes the messaging and protocols implemented at the Data Link Layer (DLL), Layer 2 in the 7-layer ISO-OSI reference model, that support reliable and efficient communications between HMS-compliant transponders interfacing to managed outside plant (OSP) network elements (NEs) and a ...
