The final conference of project ProAct, a Coordination Action financed within the Regions of Knowledge activity of the European Commission, took place on 20th of September 2007 in Prague. In ProAct, four old and four new EU member states join forces in search of the best innovation of regional innovation policy implementation. The key factors of success in the South Moravian Region in the Czech Republic are political commitment, funding and appropriate regional conditions. The regional weaknesses are the lack of skilled people for business development support. and Jiří Loudín.
Innovation Biomedical Centre (IBC) is a multipurpose and newly constructed facility located near to the Institute of Experimental Medicine (Academy of Sciences of the Czech Republic) in Prague-Krč. It was erected between August 2007 and March 2008 at a total cost of 2,1 Mil EURO. IBC was inaugurated by Prime Minister Mirek Topolánek on October 7 2008. and Eva Syková.
Insect cold tolerance mechanisms are often divided into freezing tolerance and freeze intolerance. This division has been criticised in recent years; Bale (1996) established five categories of cold tolerance. In Bale's view, freezing tolerance is at the extreme end of the spectrum of cold tolerance, and represents insects which are most able to survive low temperatures. Data in the literature from 53 species of freezing tolerant insects suggest that the freezing tolerance strategies of these species are divisible into four groups according to supercooling point (SCP) and lower lethal temperature (LLT): (1) Partially Freezing Tolerant-species that survive a small proportion of their body water converted into ice, (2) Moderately Freezing Tolerant-species die less than ten degrees below their SCP, (3) Strongly Freezing Tolerant-insects with LLTs 20 degrees or more below their SCP, and (4) Freezing Tolerant Species with Low Supercooling Points which freeze at very low temperatures, and can survive a few degrees below their SCP. The last 3 groups can survive the conversion of body water into ice to an equilibrium at sub-lethal environmental temperatures. Statistical analyses of these groups are presented in this paper. However, the data set is small and biased, and there are many other aspects of freezing tolerance, for example proportion of body water frozen, and site of ice nucleation, so these categories may have to be revised in the future. It is concluded that freezing tolerance is not part of Bale's (1996) continuum, but rather a parallel, alternative strategy of cold tolerance., Brent J. Sinclair, and Lit
In the laboratory, not all females of the seed bug Lygaeus simulans Deckert, 1985, produced fertilized eggs after copulation: 26.7% of the females were not inseminated and 5% were inseminated but did not lay fertilized eggs; only in 40% of the couples did copulation result in fertile eggs. The remaining 28.3% of couples refrained from mating. Duration of copulation was associated with insemination and fertilization: (i) fertile eggs were produced by only one couple that copulated for less than 60 min and all those that copulated for more than 360 min, (ii) probability of fertilization increased steadily with duration of copulation between 60 and 360 min, and (iii) duration of copulation was significantly different for couples that showed different insemination status.
A possible morphological explanation for this rime dependency was revealed by examining the genitalia of 69 couples freeze-fixed in copula after different periods in copulation. Because of the intricate structure of the genitalia in L. simulans, a male takes a long time to manoeuver its intromittent organ into the narrow insemination duct of the female. Only if completely inserted is the tip of the intromittent organ close enough for successful ejaculation of sperm into the spermatheca. The freeze-fixing experiment revealed that it usually took the male more than 30 min to locate the entrance to the insemination duct and another 30 min for full penetration. This explains why copulations that lasted less than 60 min failed, since insemination began only after intromission was complete.
The experiments, therefore, indicated that there is a relationship between the complex morphology of the genitalia and the low rates of insemination and fertilization in L. simulans., Thomas Micholitsch, Peter Krügel, Günther Pass, 7 obrázků, 1 tab., and Lit.
Betasyringophiloidus Skoracki, 2011 is a genus of quill mites (Prostigmata: Syringophilidae) that is believed to contain mono-, steno- and polyxenous parasites associated with a wide range of passerine birds (Passeriformes) across the world. In this work we applied the DNA-barcode marker (mitochondrial cytochrome c oxidase subunit I gene fragment, COI) to verify whether Betasyringophiloidus schoeniclus (Skoracki, 2002) and Betasyringophiloidus seiuri (Clark, 1964) are actual steno- and polyxenous species associated with the currently recognised host ranges, or their populations are highly host-specific, cryptic species. Our results revealed that a population living on the Tristram's bunting Emberiza tristrami Swinhoe (Emberizidae) in Russia, so far classified as B. schoeniclus, is a new cryptic species Betasyringophiloidus emberizae sp. nov. Both topologies of the neighbor-joining and maximum likelihood phylogenetic trees as well as genetic distance (11.9% Kimura 2-parameter distance) (K2P) support species status of the mite population from E. tristrami. The same data support previously established conspecific status of B. seiuri found on the ovenbird Seiurus aurocapilla (Linnaeus) (Parulidae) (type host) and the northern waterthrush Parkesia noveboracensis (Gmelin) (Parulidae) and expand its range with a population found on a new host species Icterus pustulatus (Wagler) (Icteridae) with intraspecific K2P distance up to 1.9% and interpopulation distances ranging from 1.3 to 3.1%., Eliza Glowska, Lukasz Broda, Miroslawa Dabert., and Obsahuje bibliografii
1. dubna 2008 byl za účasti představitelů EURATOM, Spojeného království, UKAEA (United Kingdom Atomic Energy Authority), vlády a akademické obce České republiky slavnostně odhalen tokamak COMPASS. Jedinečné zařízení získal Ústav fyziky plazmatu AV ČR, v. v. i., v rámci EURATOM od anglické UKAEA za symbolickou jednu libru, ale také za výborné výsledky při studiu vysokoteplotního plazmatu v rámci evropské spolupráce. Tokamak COMPASS je umístěn v nové budově v akademickém areálu Mazanka v Praze. Projekt převzetí tokamaku COMPASS podpořila vláda České republiky, EURATOM, UKAEA a Akademie věd ČR. Prvního plazmatu bychom se měli dočkat ještě letos., Milan Řípa, Radomír Pánek, Jan Mlynář., Součástí článku je dodatek Základní pojmy z vědeckého programu tokamaku COMPASS, and Obsahuje seznam literatury
