Mu Boötis
Mu Boötis, Latinized from μ Boötis, consists of a pair of double stars in the northern constellation of Boötes. The primary pair, components Aa, are designated μ1 Boötis and have an angular separation of 0.08 ″. The secondary, consisting of components BC, is designated μ2 Boötis and they have a separation of 2.2″. The two double star systems are separated by 107″, with matching parallaxes and proper motions, suggesting they form a system. However, compents BC have a different chemical composition compared to Aa, indicating this may instead be a close encounter between two binary systems. Mu Boötis had the traditional name Alkalurops , although the International Astronomical Union now regards that name as only applying to μ1 Boötis. Mu Boötis is approximately 121 light-years from the Sun. Nomenclature ''μ Boötis'' ( Latinised to ''Mu Boötis'') is the star's Bayer designation. It also bears the Flamsteed designation ''51 Boötis''. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clava Cairn
The Clava cairn is a type of Bronze Age circular chamber tomb cairn, named after the group of three cairns at Balnuaran of Clava, to the east of Inverness in Scotland. There are about 50 cairns of this type in an area round about Inverness. They fall into two sub-types, one typically consisting of a corbelled passage grave with a single burial chamber linked to the entrance by a short passage and covered with a cairn of stones, with the entrances oriented south west towards midwinter sunset. In the other sub-type an annular ring cairn encloses an apparently unroofed area with no formal means of access from the outside. In both sub-types a stone circle surrounds the whole tomb and a kerb often runs around the cairn. The heights of the standing stones vary in height so that the tallest fringe the entrance (oriented south west) and the shortest are directly opposite it. When Clava-type tombs still contained burial remains, only one or two bodies appear to have been buried in each, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gracile Nucleus
In neuroanatomy, the dorsal column nuclei are a pair of nuclei in the dorsal columns in the brainstem. The name refers collectively to the cuneate nucleus and gracile nucleus, which are present at the bottom of the medulla oblongata. Both nuclei contain second-order neurons of the dorsal column–medial lemniscus pathway, which carries fine touch and proprioceptive information from the body to the brain. Fibres reach the thalamus. Structure Nerve pathways The dorsal column nuclei each have an associated nerve tract in the spinal cord, the gracile fasciculus and the cuneate fasciculus. Both dorsal column nuclei contain synapses from afferent nerve fibers that have travelled in the spinal cord. They then send on second-order neurons of the dorsal column–medial lemniscal pathway. Neurons of the dorsal column nuclei eventually reach the midbrain and the thalamus. They send axons that form the internal arcuate fibers. These cross over at the sensory decussation to form th ...

Insect Morphology
Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata) (head, thorax, and abdomen), have three pairs of legs, and mouthparts located ''outside'' of the head capsule. It is this position of the mouthparts which divides them from their closest relatives, the non-insect hexapods, which includes Protura, Diplura, and Collembola. There is enormous variation in body structure amongst insect species. Individuals can range from 0.3 mm (fairyflies) to 30 cm across ( great owlet moth); have no eyes or many; well-developed wings or none; and legs modified for running, jumping, swimming, or even digging. These modifications allow insects to occupy almost every ecological niche on the planet, except the deep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
