- Subject:
- AANR, absolute retract, arc component, arc-like;, continuum, decomposable, dendroid, hereditarily unicoherent, retraction, terminal continuum, and tree-like
- Language:
- English
- Description:
- Continua that are approximative absolute neighborhood retracts (AANR’s) are characterized as absolute terminal retracts, i.e., retracts of continua in which they are embedded as terminal subcontinua. This implies that any AANR continuum has a dense arc component, and that any ANR continuum is an absolute terminal retract. It is proved that each absolute retract for any of the classes of: tree-like continua, $\lambda $-dendroids, dendroids, arc-like continua and arc-like $\lambda $-dendroids is an approximative absolute retract (so it is an AANR). Consequently, all these continua have the fixed point property, which is a new result for absolute retracts for tree-like continua. Related questions are asked.

- Subject:
- Henry of Isernia, Henricus de Isernia, Strahov Monastery, formulary, and medieval letter collection
- Language:
- Czech, English, and German
- Description:
- This study deals with a short but little researched episode in the life of Henry of Isernia, an Italian master of ars dictaminis, who came to the court of King Ottokar II of Bohemia in the early 1270s. Henry’s letter collection contains nine letters relating to his temporary stay at the Premonstratensian monastery in Strahov. These letters are impressive, but hardly interpretable, historical sources, and are also the only ones describing the circumstances of the election of a new Abbot of Strahov that probably took place in 1274. The reliability and credibility of Henry’s sometimes exaggerated and emotionally charged narratives were assessed by comparing their historical and biographical content with existing documents and memorial sources, such as monastery necrologies and annals.

765. Abelian group pairs having a trivial coGalois group
- Creator:
- Hill, Paul
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- coGalois group, torsion-free covers, and pairs of modules
- Language:
- English
- Description:
- Torsion-free covers are considered for objects in the category $q_2.$ Objects in the category $q_2$ are just maps in $R$-Mod. For $R = {\mathbb Z},$ we find necessary and sufficient conditions for the coGalois group $G(A \longrightarrow B),$ associated to a torsion-free cover, to be trivial for an object $A \longrightarrow B$ in $q_2.$ Our results generalize those of E. Enochs and J. Rado for abelian groups.

767. Ability of primary and secondary reproductives to inhibit the development of neotenics in Kalotermes flavicollis (Isoptera: Kalotermitidae)
- Creator:
- Kindl, Jiří
- Type:
- article, model:article, and TEXT
- Subject:
- Half-orphaned colonies, incipient colonies, inhibition of neotenics, and replacement reproductives
- Language:
- English
- Description:
- The inhibitory potential of primary and secondary reproductives was studied using half-orphaned colonies of Kalotermes flavicollis. Both primary and secondary reproductives (neotenics) were equally effective in inhibiting the development of replacement reproductives. Single females totally inhibited the development of female secondary reproductives but did not affect the development of male secondary reproductives. Single males had neither a stimulatory nor inhibitory effect on the development of secondary reproductives. The inhibitory ability of pairs of primary reproductives shortly after dealation and at the stage of incipient colony formation (couple with the first batch of eggs) was also examined. While pairs of freshly dealated reproductives were not able to inhibit the development of neotenics, pairs of primary reproductives that had their first batch of eggs, fully inhibited the development of neotenics.

768. Abkhaz comparatives
- Creator:
- Hewitt, George
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Abkhaz comparatives and phrases
- Language:
- English
- Description:
- This paper aims to provide a comprehensive survey of phrasal and clausal comparative constructions in the N. W. Caucasian language Abkhaz (in relation to data from the standard, Abzhywa dialect). Following the lead of Knecht (1976), the following three terms will be used throughout this article: (a) Remainder = in the phrasal comparative, a single NP (preceded by “than” in English); in the clausal comparative, the remains of the clause; (b) Trigger = the quantified constituent in the controlling clause; (c) Target = the compared constituent in the comparative clause obligatorily deleted by Comparative Deletion.

769. Abnormal neuroneal activities in intralaminar thalamic nuclei following chronic lesions of nucleus reticularis thalami in rats
- Creator:
- Pollin, B., Joulin, Y., Amsallem, B., Rokyta, R., and Cesaro, P.
- Type:
- article, model:article, and TEXT
- Subject:
- thalamus, nucleus reticularis thalami lesions, ventrobasal complex, intralaminar nuclei, pretectal area, electrical stimulation, and rat
- Language:
- English
- Description:
- Extracellular single unit activity in the intralaminar thalamic nuclei (ncl. centralis lateralis, CL, n = 77 and ncl. parafascicularis, Pf, n = 163) and in the pretectal area (Pt, n = 75) was examined following chronic electrolytic lesions of the nucleus reticularis thalami (nRT) in ketamine-anaesthetized rats after single electrical stimuli to the ventrobasal complex (VB). Extensive alterations of either the ongoing ("spontaneous") activity or the pattern of VB evoked responses were observed. Four major changes were observed in the activity of these intralaminar or pretectal neurones: 1) many neurones were silent, two times more frequently than in a parallel study with control intact rats; 2) the firing pattern of all the other neurones was in the form of tonic (stationary-like) discharge, without burst discharges as previously described in intact animals. They were ranked into classes according to their spontaneous discharge: class I, silent (no resting discharge) 12 %, class II (1-15 Hz), 54 % and class III (> 16 Hz), 34 %. Class III neurones were never found in intact rats; 3) electrical stimulation of the VB evoked a short latency orthodromic excitatory response in these neurones but this response was not followed by any slowing or depression of the spontaneous activity in more than 40 % of recorded cells. When it occurred, this pause was shorter than that always observed in intact rats by more than 35 % and longer in 7 % of the responsive cells. All these changes were correlated with the extent of damage to the ipsilateral nRT; 4) VB stimulation evoked prolonged excitatory responses lasting more than 150 ms in 13 % of the responsive cells, and nRT stimulation led to a short latency response followed by a pause of activity. These findings suggest that the nRT is involved in sensory integration and modulation.

- Description:
- Cíl: Publikace případu falešně zvýšené koncentrace bilirubinu u pacientky s mnohočetným myelomem. Metoda: U pacientky s diagostikovaným a léčeným mnohočetným myelomem byla stanovena atypicky vysoká hodnota sérového bilirubinu diagnostickým kitem Roche na přístroji Modular a normální, o dva řády nižší hodnota téhož analytu diagnostickým kitem Olympus na přístroji Olympus 400. Výsledky: Pacientka měla v krvi koncentraci paraproteinu IgG kappa 61,6 g/l. Sérový bilirubin, stanovený na přístroji Modular měl hodnotu 546 μmol/l, zatímco při opakovaném měření na přístroji Olympus 400 byla hodnota u stejné pacientky 6 μmol/l. Nižší hodnota korespondovala s klinickým stavem pacientky. Diskuse a závěr: Oba výrobci upozorňují ve svých pracovních návodech na potenciální možnost pozitivních interferencí v přítomnosti IgM lambda. Zjistili jsme extrémní pozitivní chybu o velikosti dvou řádů v přítomnosti paraproteinu IgG kappa u jednoho z nich (Roche). Chyba je snadno detekovatelná inspekcí záznamu kinetiky reakčního průběhu a neměla by ujít pozornosti při vydávání výsledků., Objective: Falsely elevated serum bilirubin in patient with multiple myeloma. Method: We determined serum bilirubin in a patient with multiple myeloma by using Modular and we repeated analysis by using Olympus 400. Results: Concentration of IgG kappa was 61.6 g/l. Serum bilirubin value measured on the Modular Roche has been 546μmol/l, while repeated measurement on Olympus 400 provided value only 6 μmol/l. Lower Olympus value corresponded to clinical status of the patient. Discussion and conclusion: Both producers introduce in their working manual the possibility of IgM lambda interference for bilirubin measurement. We found extremely high systematic error in presence IgG kappa only in Modular Roche, not in Olympus 400. Analyzer Modular Roche gives the possibility of an easy error determination by using inspection of kinetic of reaction run., Šolcová L., Friedecký Bedřich, Radocha J., Tichý M., Maisnar V., Holečková M., Vávrová J., and Lit.: 3
