In recent years, many so called "robotic toys" appeared at the market. Though these devices are called toys and they are primarily intended f.r games, they provide a set of.sensors and actuators that can be controlled f.om a computer. Hence these robotic devices may serve as non-expensive research tools, in particular f.r developing advanced sof.ware f.r controlling them. This paper describes a controller f.r landing of.an ***, a quadricopter marketed by Parrot Inc. This controller is designed f.r f.lly autonomous landing to a given visual pattern and f.r hovering above the pattern. We will show how to collect input inf.rmation f.r the controller and how to use it in a classical PID controller.

This paper summarizes recent data about magnesite and talc genesis in Carbonif.rous host rocks of.Western Carpathians (Slovakia) , which occur in two distinct belts in tectonic superunit Veporicum and its contact zone with Gemericum. The northern Sinec magnesite and talc belt (with main deposits Kokava, Sinec, Samo, Hnust'a-Mutnik) contains economic accummulation of.magnesite and talc, while in the southern Ochtina belt ( main deposits in Dubrava massif.Dubrava, Mikova, Jedl'ovec; Lubenik, Ochtina, Kosice-Bankov, Banisko, Medvedia) the magnesite is *** magnesite genesis by successive replacement of.Carbonif.rous calcite to dolomite and magnesite during metamorphic process Ml (northern belt 280-400℃; , southern belt 370-420℃: ; Radvanec & Prochaska, 2001; Kodera & Radvanec, 2002) , being supplied by Mg f.om Permoscythian evaporitic bittern brines, relates to Variscan post-collisional (post-VD) evolution.

Tectonic, microtectonic, metamorphic and geochronological data relate the talc origin with the Alpine Upper Cretaceous (88-84 Ma; Maluski in Kovacik et al. , 1996) tectonothermal event AD2. This event, being the consequence of.Alpine collisional ( AD1 ) crustal thickening and metamorphic core complex origin, meant regional extension and pervasive f.uid f.ow of.open system in crustal discontinuities.

Irritable bowel syndrome: A microbiome-gut-brain axis disorder?

引用

World Journal of.Gastroenterology 2014年第39期20卷 14105-14125页

Irritable bowel syndrome(IBS) is an extremely prevalent but poorly understood gastrointestinal disorder. Consequently, there are no clear diagnostic markers to help diagnose the disorder and treatment options are limited to management of.the symptoms. The concept of.a dysregulated gut-brain axis has been adopted as a suitable model f.r the disorder. The gut microbiome may play an important role in the onset and exacerbation of.symptoms in the disorder and has been extensively studied in this context. Although a causal role cannot yet be inf.rred f.om the clinical studies which have attempted to characterise the gut microbiota in IBS, they do conf.rm alterations in both community stability and diversity. Moreover, it has been reliably demonstrated that manipulation of.the microbiota can inf.uence the key symptoms, including abdominal pain and bowel habit, and other prominent f.atures of.IBS. A variety of.strategies have been taken to study these interactions, including probiotics, antibiotics, f.ecal transplantations and the use of.germ-f.ee animals. There are clear mechanisms through which the microbiota can produce these ef.ects, both humoral and neural. Taken together, these f.ndings f.rmly establish the microbiota as a critical node in the gut-brain axis and one which is amenable to therapeutic interventions.
