Integral part of this process is mainly evaluation of vibrations degree and behavior during actual service. Vibrodiagnostics use vibrations as a diagnostic parameter which are caused by dynamic stress to machine. This very diagnostic parameter gives information for determining actual technical condition of spinning machinery. Primary objective of machinery vibration monitoring is to supply information about machinery operating and technical condition in order to ensure strategic maintenance planning and managing. and Vibračná diagnostika využíva ako diagnostický parameter vibrácie, ktoré sú zapríčinené dynamickým namáhaním stroja, a práve tento diagnostický parameter dáva informáciu k určeniu objektívneho technického stavu rotujúcich, strojov. Základným cieľom monitorovania vibrácií rotujúcich strojov je poskytnutie informácie o prevádzkovom a technickom stave zariadenia za účelom zabezpečenia strategického plánovania a riadenia údržby.
Je popsána problematika a návrh systému pro prevenci možného vzniku síňo-jícnové fistuly při izolaci plicních žil, která je součástí elektrofyziologické srdeční operace, jejímž cílem je léčba fibrilace srdečních síní. Návrh systému pro měření jícnové teploty je aktivitou Clever Technologies, s.r.o. (spin-off firma Univerzity Karlovy v Praze a ČVUT v Praze), Společného biomedicínského pracoviště ČVUT v Praze a UK v Praze, Fakulty biomedicínského inženýrství ČVUT, 1. lékařské fakulty UK a předních klinických pracovišť. V první části je stručně podán přehled o používaných technikách při operačním zákroku při léčbě fibrilací síní, o jeho průběhu a možných komplikacích. Navazuje popis návrhu systému pro měření teploty v jícnu a charakteristika jeho řešení. and Jiří Brada, Jan Kašpar, Štěpán Královec, Pavel Smrčka, Karel Hána, Radek Fiala.
We aim to review the kinesiotherapeutic programs that have been used in therapies for patients with an eating disorder, focusing on the programs that are based on body-oriented therapies, body movements and sports. To this end we have collected and analysed the results of all the programs that have been documented and tested on clinical populations, and that were published in or before 2008. For our methodological framework we used the Systematic Review method.
Long-eared bats of the genus Plecotus are widespread over most of temperate Eurasia, marginally reaching the African continent and Macaronesia. Previously, all African populations were assigned to one species, P. auritus, and later to P. austriacus. We analysed museum specimens of African long-eared bat populations using both morphologic and genetic techniques. Based on morphological evidence we recognise four well-defined allopatric populations in northern Africa. They differ in fur coloration, skull morphology and bacular traits. The molecular data support a division of the African populations into at least three well-separated evolutionary lineages. With a combination of these data we define three species of Plecotus occurring in Africa (incl. the Canary Islands) and describe a new subspecies. Small, very pale greyish-brown Egyptian long-eared bats (P. christii Gray, 1838) inhabit desert and semi-deserts habitats of eastern Sahara (Libyan Desert, Nile Valley of Egypt and northern Sudan). Smaller to medium-sized, dark brown Ethiopian long-eared bats (P. balensis Kruskop et Lavrenchenko, 2000) inhabit the Ethiopian Highlands above 2000 metres a. s. l. This form represents the only Afro-tropical species of Plecotus. Large, dark greyish Canarian long-eared bats (P. teneriffae teneriffae Barret-Hamilton, 1907) occur on the three western islands of the Canarian Archipelago. A medium-sized greyish-brown Gaisler’s long-eared bat, P. teneriffae gaisleri subsp. n., is described from the Mediterranean region of Cyrenaica, north-eastern Libya. Due to the lack of substantial morphological differences we preliminarily consider the Maghrebian population of long-eared bats to be consubspecific with P. teneriffae gaisleri subsp. n. The systematic position of the population of Cape Verde Islands remains uncertain.
Type material of the proteocephalidean cestodes Manaosia bracodemoca Woodland, 1935 and Paramonticellia itaipuensis Pavanelli et Rego, 1991 (both monotypic genera) as well as recently collected material of the latter species are redescribed. A close similarity between both species was observed: the shape of scoleces is identical, both possess a globular scolex with hidden suckers, a well-developed circular, horseshoe-shaped musculature surrounding suckers; the measurements of both taxa are also similar (scolex, suckers, young proglottides). Both cestodes possess a medullary ovary crossing the dorsal muscle layer and ending in the dorsal cortex, the testes are in the dorsal cortex and the cortical vitellarium is laterally situated. Both species parasitize the same fish host. Therefore Paramonticellia is considered a junior synonym of Manaosia and Paramonticellia itaipuensis becomes a junior synonym of Manaosia bracodemoca. An emended diagnosis of Manaosia, which is a monotypic genus, is provided.
The systematic status of the gonad-infecting Philometra species previously reported as P. lateolabracis (Yamaguti, 1935) from marine fishes in the Mediterranean region and off New Caledonia is evaluated with respect to the recent redescription of P. lateolabracis from the type host in Japan. Philometra jordanoi (López-Neyra, 1951) is revalidated to accommodate the nematodes from Epinephelus marginatus, whereas the philometrids from other European hosts (Mycteroperca rubra and Seriola dumerili), as well as those from the gonads of Epinephelus cyanopodus and E. fasciatus off New Caledonia, should be reported as Philometra sp. until new data are available. Also the philometrids reported as P. lateolabracis from Parupeneus indicus from off Somalia should be designated as Philometra sp. for the time being.
Reexamination of the male holotype of the rhabdochonid nematode Rhabdochona leucaspii Kritscher, 1979, originally described from the intestine of the cyprinid fish Leucaspius prosperi [= Ladigesocypris ghigii (Gianferrari)] from Rhodes Island, Greece, confirmed its morphological and biometrical identity with Rhabdochona denudata (Dujardin, 1845), a common and widespread parasite of cyprinids and some other fishes in palaearctic Eurasia. Consequently, R. leucaspii is considered a junior synonym of R. denudata.
Cuckoos parasitize many rare and inconspicuous host species but avoid other common and conspicuous ones. In this article, results of a study that solved this long-standing ecological conundrum are described. I use this work to illustrate va - rious weaknesses of typical ecological studies (sample size, data representativeness, reification) and give suggestions for a better research practice in the future. and Jiří Klimeš, Ivan Literák.
