Pharmakologisch-aktive polymere, 21. Orientierende Untersuchungen zur körperverteilung und Ausscheidung von poly[2-(methylsulfinyl)ethylacrylat]en be…

1980

Poly[2-(methylsulfinyl)ethyl acrylate] (1) was synthesized as well as derivatives 14C-labelled in side groups (6) or 14C-labelled in the main chain (11). Polymer 11 with the 14C-labelled main chain was fractionated by precipitation. The η-M-relation determined by measurements of unlabelled polymers in the ultracentrifuge for comparison was used to establish the viscosimetrically determined molecular weights of the labelled fractions. After intravenous application of aqueous solutions of the polymer in rats the excretion rate up to 72 h after treatment was ascertained to ca. 50%; the concentration in the blood serum was found to be strikingly high. A tendency to reinforced storage in organs …

Separation of chitosomal chitin synthetase from cell-free extracts ofNeurospora crassa “Slime” variant agglutinated with concanavalin A

1989

Cell-free extracts of the wall-less slime variant ofNeurospora crassa were treated with concanavalin A (Con A); this treatment caused a massive agglutination of the particulate structures in the cell-free homogenate, although most (73%) of the chitin synthetase initially present in the cell-free extract remained in the supernatant obtained after sedimentation of the lectin-flocculated material. This chitin synthetase showed the sedimentation properties of chitosomes (unique microvesicular structures) and failed to bind [3H]Con A. A significant percentage (42%) of the chitin synthetase activity associated with the Con A-flocculated material probably corresponds to mechanically trapped chitos…

Simultaneous Automated Determination of Catecholamines, Serotonin, and Their Metabolites in Brain Tissue by HPLC and Electrochemical Detection

1993

Abstract A robust procedure with minimal tissue sample pretreatment, based on reversed-phase, ion-pair high performance liquid chromatography (HPLC) combined with electrochemical detection has been developed for the automated and simultaneous determination of the biogenic amines norepinephrine (NE), epinephrine (E), dopamine (DA), 5-hydroxytryptamine (5-HT) and their metabolites 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG), 3,4-dihydroxyacetic acid (DOPAC), homovanillic acid (HVA) and 5-hydroxyindolacetic acid (H I A A) in as little as 0.5 mg brain tissue. The chromatographic conditions remain stable for at least 8 weeks. In particular small amounts of samples which do not allow reexamina…

Early Protestant spirituality

2018

Wiele aspektów wczesnej duchowości protestanckiej (mamy na uwadze szczególnie XVI stulecie) utrudnia usystematyzowanie jej w kontekście narastającej tendencji analizy tego okresu. Zainteresowanie wczesną duchowością protestancką znacznie wzrosło wśród badaczy w ciągu ostatnich dziesięcioleci. Konieczna stała się więc selekcja wyników badań. Uwzględnione zostały tylko te, które dotyczą najważniejszych jej wątków i tematów. Zasadniczym celem tego opracowania stało się przedstawienie możliwie jak najbardziej klarownego jej obrazu. Mając to na uwadze, w szesnastowiecznej duchowości protestanckiej wyróżniliśmy następujące rysy: biblijny, chrystocentryczny oraz kościelno-wspólnotowy. W różnych ok…

Cilvēka cieņas koncepts saistībā ar tiesībām dzīvot labvēlīgā vidē

2019

Sākot ar pagājušo gadsimtu, kad iedzīvotāju skaita pieaugums uz Zemes piedzīvoja strauju kāpumu, visi procesi, kas saistīti ar cilvēces uzturēšanu, galvenokārt rūpniecība, pārtikas sagāde un lauksaimniecība, transports atstāj arvien nelabvēlīgāku ietekmi uz vides stāvokli visā pasaulē. Saskaņā ar cilvēktiesībām un cilvēka cieņas konceptu, par augstāko vērtību uzskatāms ir cilvēks, tomēr šāda nostāja ne tikai apdraud planētas veselību, bet arī pašus cilvēkus. Tuvojoties brīdim, kad vairs nebūs iespējams apturēt vides stāvokļa pasliktināšanos, ir nozīmīgi rast risinājumus, kuri gādātu par to, ka cilvēki par savu apkārtējo vidi rūpējas un ikvienu organismu tajā respektē.

Klimata pārmaiņas Ričarda Pouersa romānā "The Overstory"

2022

Darbs pēta klimata pārmaiņu fenomenu Ričarda Pouersa romānā The Overstory, analizējot to no ekokritikas perspektīvas. Pētījuma metodes ietver klimata pārmaiņu, to attēlojuma literatūrā un ekokritikas teorētisko pētījumu, kā arī praktisko pētījumu (detalizētu lasīšanu un ekokritisku analīzi). Pētījuma rezultāti liecina, ka daba un klimata pārmaiņas romānā attēlotas kā process, ko ietekmē cilvēku rīcība. Cilvēku un pārējo varoņu (koku) attiecības ir attēlotas, balstoties uz Gajas mītu, paralēlās pasaules, civilizācijas projekta teoriju, kā arī vairākiem garīgiem mītiem un uzskatiem. Katrs no galvenajiem cilvēku tēliem ir saistīts ar savu koka tēlu, tomēr romānā ir arī uzsvērts, ka viss dabā i…

Il sistema dei valori nel centro storico di Palermo

2007

Questo saggio approfondisce il tema del rapporto tra soggetti pubblici e privati nell’ambito delle trasformazioni urbane che riguardano, in particolare, i centri storici. Sono state analizzate le cause e le condizioni (macro e micro-economiche, macro-micro-territoriali, culturali, ecc.) che hanno determinato un cambiamento del sistema di valori (immobiliari) del centro storico di Palermo rispetto ai valori del sistema urbano, e si propone di definire le condizioni di convenienza economica dei soggetti pubblici e privati nell’investimento in interventi di riqualificazione degli spazi pubblici e di recupero del patrimonio edilizio storico. L’obiettivo è quello di fornire un modello di riferim…

Urban Growth and Real Estate Income. A Comparison of Analytical Models

2016

I processi di crescita urbana sono notoriamente complessi dipendendo da un’ampia varietà di fattori demografici, socio-culturali ed economici. L’analisi è ancora più complessa nelle aree metropolitane che sono il risultato di antichi processi di agglomerazione in una fase d’intenso accrescimento dell’insediamento e, più recentemente, della formazione di policentrismo urbano. L’investigazione richiede l’acquisizione, l’analisi e l’elaborazione d’idonee informazioni a livello delle unità territoriali omogenee, basandosi su modelli consolidati o su nuovi protocolli da verificare. Il presente contributo analizza la crescita urbana secondo un approccio di piccola scala, individuando i distretti …
