Abstract:

Four isolated occurrences of Tertiary volcanic rocks in the northern Spessart at Beilstein, Hoher Berg, Madstein and Kasselgrund are relics of volcanic vents or dikes. They display alkaline basalts (s. l.) with mainly trachybasaltic composition, which, from normative mineral contents, may be designated as nepheline-bearing alkali-olivine basalts and basanites. In part, centimetre-sized xenoliths of spinel lherzolite occur. According to Ar-Ar dating, the alkaline basalts (s. l.) from Kasselgrund have erupted at 18.1 ± 0.3 or 19.3 ± 0.4 Ma, those of Hoher Berg between c. 18 and c. 21 Ma. These ages correspond to the Vogelsberg eruption stage I. A slightly younger Ar-Ar age of 16.8 ± 0.3 Ma was recorded for the Beilstein basalt, which is in chronological accordance to the turn of Vogelsberg eruption stages II and III. Samples of all four occurrences reveal major and trace element compositions, which are different from those of the Vogelsberg basalts. Compositions of basalts of the stage III from Vogelsberg coincide most with the Spessart basalts. This signals a special position of the northern Spessart volcanic rocks either as a discrete spatial part of the Vogelsberg volcanic suite or as smaller, independent eruption centres.

Abstract:

AbstractPost-Variscan vein-type Co-Ni-Bi ores of the Bieber deposit, Spessart mountains, Germany, which are related to the Permian Kupferschiefer, have been investigated by ore microscopy, X-ray powder diffraction and electron-probe microanalysis. The samples contain a variety of ore minerals, notably skutterudite, native bismuth, cobaltite, alloclasite, niccolite, maucherite, gersdorffite, rammelsbergite/pararammelsbergite, safflorite, loellingite and emplectite. The ores display structures indicative of multiple brecciation and complex zoned arsenide assemblages. Three sequential stages of deposition are identified, which are (1) the Cu stage, (2) the main Co-Ni-Bi stage, and (3) the late stage. The arsenide minerals, notably skutterudite, diarsenides and sulpharsenides, show a large range of compositional variation in Co-Ni-Fe space. A relatively limited number of skutterudite and diarsenide compositions lie outside the compositional fields established in the literature. Skutterudite and diarsenides are characterized by a significant substitution of As by S up to 0.44 a.p.f.u. and 0.31 a.p.f.u., respectively, which is larger than the range previously reported for these minerals. Sulpharsenide compositions can be grouped into three populations, which conform to cobaltian arsenopyrite, cobaltite and gersdorffite. They display highly variable As/S ratios between 0.95:1.00 and 1.29:0.73, consistent with experimental data. Estimates of the formation temperatures, based on the presence of dendritic native bismuth and emplectite, are in the range 100–300°C, similar to different post-Variscan mineralization styles widespread in Central Europe. Comparison of the Co-Ni-Bi vein assemblage with the framework of available paragenetic information and radiometric age data for regional mineralization events indicates an age of mineralization of ~150–160 Ma for the Bieber deposit.

Abstract:

The rapid decline of German emigration before World War I constitutes a puzzle that traditional explanations have difficulty in solving. The article shows that the social legislation implemented by Bismarck during the 1880s—the most developed at the time—played a key role in this process. Indeed, candidates for migration considered not only the gap between “direct wages” (labor earnings) in the United States and Germany, but also the differential in “indirect wages,” that is, social benefits. In that way, Bismarck's insurance system partly offset low wage rates in Germany and furthered the fall of the emigration rate.O sprecht! warum zogt ihr von dannen?Das Neckartal hat Wein und Korn;Der Schwarzwald steht voll finstrer Tannen,Im Spessart klingt des Ålplers Horn.Wie wird es in den fremden WäldernEuch nach der Heimatberge Grün,Nach Deutschlands gelben Weizenfeldern,Nach seinen Rebenhügeln ziehn!Ferdinand Freiligrath1

Abstract:

AbstractAllozyme electrophoresis of 14 loci provided information on the distribution of the two central European subspecies of the fire salamander, Salamandra salamandra salamandra (dotted taxon) and S.s.terrestris (striped taxon), along an east-west-transect in Germany. 2183 larvae from 48 populations situated in 14 mountain ranges were studies. A broad (about 140 km wide) zone of intergradition between the two forms is described, ranging from the Hunsrück Mountains in the west to the Spessart in the east. Within this hybrid zone the populations are panmictic. Focussing on the Rhenish Slate Mountains, the western border of the hybrid zone is described in detail. A comparison between allozyme data and morphognostical data (drawn from literature) on the dorsal pattern indicates a discordance between the two data sets. Consequently, the dorsal pattern is ruled out as an indicator for the detection of hybrid populations.

Abstract:

Abstract Provenances originating from French and German sessile oak seed sources were analysed 23 years after planting at nine different locations in Northwest Germany. In general, German provenances are better adapted to the prevailing conditions of the test sites showing a better survival. Differences between the provenances in measured growth characters (“DBH”, “height”) were less pronounced than in observed quality parameters (“form”, “crown”). Five of the German provenances showed a better stem form; only three French provenances exceeded the overall mean. Variation in phenotypic stability between provenances could be observed as well as rank changes of provenances measured at different ages. Observed variation in stability was mainly attributable to single provenances, however, no pattern of variation could be detected. Besides the German seed sources “Bundesgebiet”, “Spessart” and “Göhrde” some French provenances (“Reno Valdieu”, “Bertranges”, “Darney” and “Der”) can be recommended as substitute in low crop years.

Abstract:

Aquatic ecosystems can be either permanently wet or be subject to seasonal or intermittent drying. Insect species inhabiting temporally dry streams have evolved behavioural, morphological and/or life history traits to ensure their persistence. The limnephilid caddisfly Micropterna lateralis (Stephens 1837) has a life cycle that is tailored to the temporal dynamics of periodically dry streams where adults usually hatch before drought commences. Their aquatic larvae are, however, also able to survive stream drying, but the mechanisms driving this survival ability have not been studied to date. We conducted an experiment to simulate drying conditions, using samples from a M. laterialis population taken from an intermittent stream in the Spessart Mountains of the central German highlands. The experiment simulated three hydrological conditions: wet, moist and dry. In a first test of our system we compared gene expression profiles of three individuals (one per condition) using Illumina-based Massive Analysis of cDNA Ends MACE-Seq. Our first results show large differences in gene expression between the studied phases with many genes exhibiting gradual up- or down-regulation across the three experimental hydrological conditions. Under drought stress, up-regulation was primarily found in genes controlling production and mobilization of desiccation protectants, mainly sugars, whereas down-regulated genes were related to cuticle organisation and lipid metabolism. These preliminary results give valuable insights into genetic and physiological responses of aquatic insects to stream drying.

Abstract:

Zusammenfassung Biodiversität ist in ihrer Komplexität nicht einfach messbar – zu ihrer Quantifizierung bedarf es einer Auswahl von (Tier- und Pflanzen-)Arten, die Biodiversität repräsentieren. Die kriteriengestützte systematische Selektion von Zielarten als Stellvertreter der Lebensgemeinschaften (Biozönosen) in den charakteristischen Biotop- bzw. Ökosystemtypen eines Planungsraumes stellt eine pragmatische Lösungsmöglichkeit dar, um Ziele des Naturschutzes qualitativ und quantitativ herzuleiten und zu begründen. Sie bietet einfache Indikatoren, um unter anderem die Nachhaltigkeit von Flächennutzungen und den Erfolg von Naturschutzmaßnahmen nachzuweisen und um Schutzziele in der Öffentlichkeit zu kommunizieren. Das gilt ganz besonders in Großschutzgebieten, die gemäß Zielbestimmung als großräumige Landschaftsausschnitte Schutz- und Nachhaltigkeitsziele erfüllen sollen. Der Beitrag definiert den Begriff und die Funktionen von Zielarten mit besonderem Blick auf Großschutzgebiete. Am Beispiel der Naturparke Spessart und Diemelsee wird das methodische Vorgehen zur Aufstellung eines Zielartenkonzepts mit anzuwendenden Kriterien beschrieben. Im Falle des Naturparks Diemelsee erfolgt dabei ein besonderer Fokus auf Pflanzen- und Tierarten, die empfindlich auf den Klimawandel reagieren, weil diese in besonderem Maße schutzrelevant sind. Ein innovativer Ansatz beschreibt den Einsatz von Zielarten im Rahmen einer Vermarktung von Bioprodukten aus Biosphärenreservaten, welche belegbar Biodiversität fördern. Zielarten müssen so ausgewählt werden, dass ihr Raumanspruch der jeweiligen Planungsebene angemessen ist. Dann können sie Schutzanliegen der Biodiversität in raumrelevante Planungen integrieren. Die zielartenbezogene Bewertung erlaubt die frühzeitige Identifikation möglicher Konfliktpunkte und deren planerische Bewältigung. Dies entlastet, beschleunigt und verbilligt spätere fachplanerische Festsetzungen.

Abstract:

Abstract. The reversal of freshwater acidification in the low mountain ranges of Germany is of public, political and scientific concern, because these regions are near natural ecosystems and function as an important drinking water supply. The aim of this study was to evaluate the status and trends of acidification reversal after two decades of reduced anthropogenic deposition in selected freshwaters of the low mountain ranges in the Harz, the Fichtelgebirge, the Bavarian Forest, the Spessart and the Black Forest. In response to decreased sulphate deposition, seven out of nine streams investigated had significantly decreasing sulphate concentrations (all trends were calculated with the Seasonal Kendall Test). The decrease in sulphate concentration was only minor, however, due to the release of previously stored soil sulphur. No increase was found in pH and acid neutralising capacity (defined by Reuss and Johnson, 1986). Aluminum concentrations in the streams did not decrease. Thus, no major acidification reversal can currently be noted in spite of two decades of decreased acid deposition. Nevertheless, the first signs of improvement in water quality were detected as there was a decrease in the level and frequency of extreme values of pH, acid neutralising capacity and aluminium concentrations in streams. With respect to nitrogen, no change was determined for either nitrate or ammonium concentrations in precipitation or stream water. Base cation fluxes indicate increasing net loss of base cations from all ecosystems investigated, which could be interpreted as an increase in soil acidification. The latter was due to a combination of continued high anion leaching and significant reduction of base cation deposition. No major improvement was noted in biological recovery, however, initial signs of recovery were detectable as there was re-occurrence of some single macroinvertebrate species which were formerly extinct. The results of this study have important implications for water authorities, forest managers and policy makers: the delay in acidification reversal suggests a need for ongoing intensive amelioration of waters, a careful selection of management tools to guarantee sustainable management of forests and the reduction of nitrogen deposition to prevent further acidification of soils and waters.

Abstract:

Lo studio RM della regione sellare si avvale di una tecnica ormai standardizzata; le sequenze abitualmente realizzate sono Spin-Echo ponderate in T1 (SE T1W) (TR = 550, TE = 20, 4 acquisizioni), Field of view (FOV) <20 cm, matrice 256, secondo piani coronali e sagittali, con sezioni di 3 mm di spessore. Sezioni di spessore sottile, con alta matrice e FOV ridotto, dotate di buon rapporto segnale rumore potevano essere prodotte fino a poco tempo fa solo da apparecchi ad alto campo magnetico, ma attualmente anche dai più recenti apparecchi 0,5 T. Le sequenze Densità Protonica e T2W sono generalmente limitate allo studio di lesioni ad estensione extrasellare. I mezzi di contrasto paramagnetici vengono utilizzati sempre più frequentemente come completamento della indagine allo scopo di aumentare la sensibilità nei confronti di patologie di piccole dimensioni, introdurre ulteriori elementi di specificità e permettere una miglior delimitazione delle lesioni rispetto alle strutture viciniori. Sequenze Gradient Echo 3D, con acquisizione volumetrica, appaiono secondo i primi risultati molto promettenti 18in quanto permettono di ottenere sezioni di spessore fino ad 1 mm, ralmente contigue e senza effetti di interferenza o di volume parziale tra fette adiacenti, con possibilità di ricostruire successivamente immagini secondo piani diversi dalla orientazione originaria. In sintesi è stato possibile ottenere una buona risoluzione spaziale, necessaria per lo studio della sella e del suo contenuto, in una metodica caratterizzata da alta risoluzione di contrasto, dalla multiplanarità e dalla assenza di artefatti da osso e da amalgami dentari oltre che di radiazioni ionizzanti. Per queste ragioni la RM è attualmente l'esame di prima scelta nello studio delle patologie della regione sellare.

Abstract:

L’articolo, dopo aver analizzato gli aspetti etici legati alla medicina predittiva e dopo aver illustrato la malattia di Alzheimer da un punto di vista patologico ed eziologico, si sofferma sulla significatività etica del ruolo del counseling genetico, in particolare in relazione al caso in cui la richiesta del test predittivo venga da parte di soggetti a rischio, asintomatici, che presentano una familiarità la cui eziologia è nota, e per i quali il test è disponibile. In questo caso la riflessione etica è maggiormente problematizzante e coinvolge diversi aspetti: l’uso di test sicuri ed efficaci in strutture sanitarie ben identificate con standard di qualità garantiti; le problematiche legate alla consulenza (autonomia decisionale dell’utente, il consenso informato, l’assistenza psico-sociale); la formazione professionale del personale sanitario. In seguito gli autori riportano e commentano i dati di un’indagine conoscitiva in merito al test predittivo e alle strutture sanitarie. Infine, nel delineare le direttive etiche per i consulenti, viene messo in risalto lo spessore bioetico e biogiuridico del ruolo dell’operatore nel counseling genetico, spessore che viene ulteriormente messo in luce dalla peculiare responsabilità che l’operatore si assume nella protezione dei dati genetici.

Abstract:

Nonostante i deludenti esordi nella valutazione delle strutture labirintiche costituenti l'orecchio interno, la risonanza magnetica costituisce oggi, grazie anche al miglioramento dell'hardware e del software disponibili, una modalità diagnostica di grande efficacia non solo nell'analisi della patologia espansiva o infiammatoria coinvolgente il VII ed VIII nervo cranico, ma anche nella valutazione delle alterazioni patologiche del segnale endolabirintico in rapporto a focolai emorragici o, come recentemente dimostrato mediante uso di Gd-DTPA, nell'analisi delle alterazioni a carico della capsula oticanella fase spongiotica dell'otosclerosi. Tuttavia, lo scarso contrasto esistente tra liquido endolabirintico e strutture circostanti (solitamente aria nel cavo timpanico e tessuto osseo capsulare) rende le tradizionali scansioni in tecnica Spin-Echo con ponderazione T1 del tutto inadeguate alla valutazione dell'orecchio interno. Analoga osservazione deve essere fatta per le immagini T2-dipendenti che, per l'eccessivo spessore di scansione e l'elevata durata dei tempi di esame, non rappresentano di certo un mezzo di indagine pratico ed affidabile, certamente comunque non competitivo nei confronti dell'imaging TC, oggi particolarmente fedele grazie alla possibilità di effettuare scansioni di minimo spessore (1 mm). Gli autori riportano la loro esperienza nell'analisi delle strutture labirintiche nel normale e patologico mediante imaging per RM con unità operante a 0,5 T ed applicazione di sequenze di tipo GRASS, opportunamente modificate per aumentarne la sensibilità al flusso lento endolinfatico (mGRASS), e Fast-Spin-Echo (FSE). Nei casi patologici è stata effettuata una analisi comparativa rispetto al reperto TC.

Abstract:

Nella relazione tra lingua e genere, la prospettiva terminologica e lessicografica risulta assai promettente per lo spessore delle sedimentazioni culturali di cui si carica. Se consideriamo infatti i dizionari come delle opere "ideologiche", che riflettono la mentalità dei loro fruitori e dei loro redattori, non è quindi raro imbattersi in definizioni e esempi che mostrano delle dissimetrie di trattamento dei significati attribuiti agli uomini e alle donne. In questo lavoro si desidera osservare l'immagine sociale così come è riflessa in un vocabolario (GRADIT), ovvero nelle scelte di tipi lessicali legate alla donna e, ove necessario, all'uomo. Si potrà così rilevare l'esistenza di giudizi cristallizzati, stereotipi e quindi di aspettative socialmente condivise nelle opzioni lessicali del repertorio in questione, ma soprattutto nell'ampia varietà di esempi che corredano i singoli lemmi.

Abstract:

Attualmente la RM rappresenta la sola modalità di studio neuroradiologico dei nervi cranici e la sua introduzione nella pratica clinica ha rappresentato un grande progresso nella diagnostica in questo campo. Abbiamo effettuato una valutazione dell'anatomia RM dei nervi cranici utilizzando tecniche differenti, caratterizzate essenzialmente da alta risoluzione spaziale e di contrasto; esse (sia Turbo Spin Echo sia ad eco di gradiente) consentono di ottenere immagini di ridotto spessore, anche inferiore al mm, e risultano perciò di grande utilità nello studio delle fini strutture anatomiche. Nel nostro lavoro illustriamo le potenzialità diagnostiche di queste tecniche più recenti rispetto alle tradizionali tecniche Spin Echo nello studio dei nervi cranici la cui complessa patologia richiede al radiologo grande esperienza nella scelta delle sequenze e dei piani di studio più idonei per la valutazione del singolo nervo cranico.

Abstract:

Le sequenze RM veloci possono essere utilizzate per effettuare studi ad alta risoluzione spaziale in tempi di acquisizione comparabili con le sequenze tradizionali. Le tecniche Turbo Spin Echo, rispetto a quelle ad eco di gradiente, risultano particolarmente indicate a questo scopo perché sono caratterizzate da una elevata risoluzione di contrasto delle immagini dipendenti dal vero T2, e non dal T2*. Esse presentano inoltre una minore incidenza di artefatti da suscettibilità magnetica, che può apparire uno svantaggio in determinate situazioni cliniche, ma che risulta invece assai utile nello studio RM dell'osso temporale, ove sono innumerevoli le interfaccie osso-aria. La possibilità di ottenere sequenze Turbo Spin Echo di spessore di strato inferiore al millimetro consente di effettuare uno studio dettagliato del condotto uditivo interno e delle strutture vascolari e nervose che lo percorrono.

Abstract:

L’autore dell’articolo indica certe mancanze nell’atteggiamento, sia dei sacerdoti che dei laici, di fronte al sacramento dell’Eucaristia. L’antidoto contro questa situazione, lo vede in una migliore formazione biblica e liturgica di tutto il popolo di Dio, nell’obbedienza alle norme liturgiche e in una più spessa e profonda partecipazione alla Comunione sacramentale e spirituale, che contiene tutto il bene della Chiesa, cioè il Cristo stesso. I responsabili della giusta devozione eucaristica sono soprattutto i ministri dell’Eucaristia, che devono cercare di celebrare la liturgia della Santa Messa in modo appropriato ed educare così tutti al debito rispetto verso questo grande mistero salvifico.

Abstract:

Nella campagna di scavi condotta a Cirene tra l'ottobre del 1910 ed il maggio del 1911 la Missione Archeologica Americana diretta da Richard Norton portava alia luce circa tremila statuine fittili, intere o quasi, ed una quantità innumerevole di testine ed altri frammenti.L'occasione per la scoperta era stata del tutto fortuita. Agli inizi di novembre del 1910 un arabo si era presentato al campo portando un cesto con 765 statuette di terracotta, che erano state scavate nel suo giardino posto alle pendici dell'Acropoli, nella parte nord-occidentale, al livello della Terrazza del Santuario di Apollo (la Myrtousa).Molte conversazioni e molti caffè consentirono al Norton l'inizio dello scavo, in una striscia piana posta a valle di un gradino roccioso. Nel sito non si rinvennero resti di edifici, ma diverse nicchie rettangolari scavate in alcuni speroni di roccia. Immediatamente davanti a queste vennero trovate le statuette di terracotta: esse formavano uno strato dello spessore di una novantina di centimetri.
