Neurosurgery of Malignant Brain Tumors
1987
To Virchow 167 belongs the credit of identifying as tumors, tissue changes already described in the brain, and at the same time to have published an account of the characteristics of the gliomas and the first classification of the various types. It was only the knowledge of the neoplastic nature of the gliomas 127 which made possible surgical action with the aim of extirpation (Fig. 1), when at the end of the 19th century the stormy development of surgery in other parts of the body was being practised successfully 162. The first reports about the removal of an intracerebral space-occupying lesion came from Wernicke and Hahn (1881)183 and also from Bennett and Godley (1884)16. In both cases …
Trichomonazide Wirkstoffe, 3. Mitt. Aryloxy-chlor-1,3,5-triazine
1987
Die Umsetzung von 2,4-Dichlor-6-(dihexylamino)-1,3,5-triazin (1) mit Phenolen (2) fuhrt bei niedrigen Temperaturen zu den Monoaryloxy-chlor-1,3,5-triazinen (3a–c), unter drastischeren Reaktionsbedingungen zu den Bis-(aryloxy)-1,3,5-triazinen (4c–d). Fur die neuen Verbindungstypen ist besonders charakteristisch die massenspektroskopische Abspaltung der Aryloxygruppen, beispielsweise in 4c der Ubergang von m/z 504 nach m/z 383. Auffallende trichomonazide und blutzuckersenkende Wirkungen vermag insbesondere 3b auszulosen.

Effect of Bisacodyl on Intestinal Electrolyte and Water Net Transport and Transit
1987
The effect of bisacodyl on intestinal electrolyte, glucose, and water transport, and transit was studied in 6 healthy volunteers by intestinal perfusion. A 5-lumen tube with an occluding balloon allowed constant perfusion (10 ml/min) of 30 cm of the upper jejunum and a rapid collection of the perfusate free of contaminants. A phenol red bolus was injected into the tube and its passage through the test segment was calculated by dye dilution formula. A 1-hour control period was followed by a test period with 6 mg/h bisacodyl and followed by 2 other 1-hour control periods. Net absorption of Na+ (0.35 +/- 0.08 mmol/min) and water (1.7 +/- 0.6 ml/min) changed to net secretion (Na+ -0.93 +/- 0.3 …
On the Volcanology of the West Eifel Maars
1987
The Quaternary alkali-basaltic volcanic field of the West Eifel is the classic maar region of the world. Related to the formation of the continental rift zone which extends through Central Europe, ultrabasic magmas rose from the upper mantle through the continental crust and fed 240 small volcanoes. Next to scoria cones with their lava flows, maars are most frequent and represent 25% of the volcanoes. Since 1820 and until 1970 their origin was mostly believed to be related to explosive exsolution of juvenile volatile phases. Since 1970, however, several authors have suggested that the West Eifel maars are phreatomagmatic in origin, i.e. rising magma contacted groundwater in near-surface lev…
Effect throughout the day of inhaled fenoterol on the bronchial responsiveness to histamine in asthmatic patients.
1987
The effect throughout the day of inhaled fenoterol on the bronchial responsiveness to inhaled histamine was evaluated in 8 asthmatic patients. The airway response to increasing concentration of histamine aerosol was assessed by measurement of forced expiratory volume in one second (FEV1). The provocative dose of histamine needed to cause a 20% fall in starting FEV1 was calculated from the cumulative log dose response curves. Histamine challenges were performed in duplicate, on separate days, after premedication with placebo or fenoterol given by metered dose inhalers in the morning and in the afternoon. The mean starting FEV1 in the morning and in the afternoon did not change significantly …
Inhibitory influences of vagal afferences on the oesophageal EMG peristaltic pattern
1987
AbstractThe influence of vagal afferents on the EMG peristaltic pattern was studied in pigeon oesophagus.Bilateral vagotomy did not abolish the primary peristalsis, but induced significant modifications of the peristaltic pattern parameters.Vagal afferent stimulation induced an inhibitory effect consisting of a temporary break or definitive block of the EMG peristaltic activity already in progress.Vagal afferent stimulation also induced a reduction of the spontaneous EMG activity and this effect was abolished either by glossopharyngeal bilateral section or ganglionic block.Likewise vagal afferent stimulation, the crop distension caused inhibitory effects on EMG peristaltic pattern. This eff…

24. Molecular Biology
1987
Publisher Summary This chapter discusses the use of neutron scattering in molecular biology. The neutron small-angle camera D11 is discussed. The objective of scattering studies on biological macromolecules is to determine molecular conformations and arrangements, particularly those that may contribute to specific biological functions. The principles of neutron scattering are very similar to those of x rays, but some important differences exist due to the different characteristics of the two radiations. If the scattering specimen is a single macromolecule with no regular separation between neighboring structures, then the scattering is continuous. In a coherent scattering process, the ampli…
Energy Conscious Building Design
1987
Since the beginning of energy crisis many design tools have been developed in order to enable the designer to cope with energy consumption in buildings. These tools are of different kind: from very sophisticated simulation models to simplified (often too much) methods. Each of them offers various advantages and disadvantages, and it is up to the designer to choose among them.

Offensive and defensive aggression in humans: A longitudinal perspective
1987
Offensive and defensive aggression were distinguished on the basis of associated events. Behavior delivering noxious stimuli was defined as defensive when it was a response a threatening situation and as offensive when it was an unprovoked act. The existence of a general aggression factor was implied by the finding that initiators of aggression also readily defend themselves if attacked. The use of a peer nomination and teacher rating variable for offensive aggression, “Attacks without reason, teases others, naughty things”; and another for defensive aggression, “Defends him/herself if teased, but does not tease or attack others without reason,” yielded differential results. Offensive aggre…
Ostajat, lukijat, arvioijat, tukijat : lukijoiden ja kriitikoiden kirjallisuus suuren muuton jälkeisessä Suomessa
1987
Tutkimuksessa verrataan lukijoiden ja kirjallisuuskriitikoiden suosikkikirjallisuutta. Aineistona ovat Helsingin Sanomissa vuosina 1967-87 julkaistut "Nämä kirjat käyvät kaupaksi...mutta älkää unohtako näitä" -listat, joissa esitellään hyvin kaupaksi käynyttä kirjallisuutta ja kriitikoiden arvostamaa kirjallisuutta. Listojen perusteella selvitetään näiden kahden kirjallisuuden kentän välisiä yhtäläisyyksiä ja eroja. Tähän liittyen kartoitetaan myös korkea- ja populaarikulttuurista käytyä keskustelua. Kirjallisuuden perusteella yritetään lisäksi vastata kysymykseen, millainen on Suuren muuton jälkeinen suomalainen kulttuuri: mistä tulevat kulttuuriset vaikutteet, ja säilyykö suomalainen yhte…

La boveda plantar
1987
The foot vault is the most distinguished morphological feature of the human foot. It is formed by a complex visco-elastlc functional system made out of muscle, dermoaponeurotic and osteo-Iigament components. These will all gather in different joint units which will supply it with the essential stíffness, in order to support the mechanical demands. Its philogenetic evolution - in the same way as the architectural disposition brings us to the conclusion that, after all, a spareness of material takes place within a specialized designo

Invariants of unipotent groups
1987
I’ll give a survey on the known results on finite generation of invariants for nonreductive groups, and some conjectures. You know that Hilbert’s 14th problem is solved for the invariants of reductive groups; see [12] for a survey. So the general case reduces to the case of unipotent groups. But in this case there are only a few results, some negative and some positive. I assume that k is an infinite field, say the complex numbers, but in most instances an arbitrary ring would do it.
Die Notwendigkeit der Gesamtwirtschaftlichen Stabilisierung
1987
Obwohl die Anzahl der abhangig Beschaftigten in der Bundesrepublik Deutschland in den vier Jahren von 1980 bis 1984 um ca. 1 Million gesunken war, namlich von 23 Mio (1980) auf 22 Mio (1984), stieg im gleichen Zeitraum die Arbeitslosenquote von 3,8% (1980) auf 9,1% (1984) mit einem Nachkriegsmaximum von 10,6% im Januar 1985, was 2,619 Mio Arbeitslosen entsprach (vgl. Tab. 1.1). Dazu kamen noch 384.000 Kurzarbeiter im Jahre 1984 gegenuber 137.000 im Jahre 1980. Im Vergleich zu den 60er Jahren, in denen mit Ausnahme der Jahre 1967 und 1968 die Arbeitslosenquoten unter 1% lagen, was weniger als 200.000 Arbeitslosen entsprach, hat sich seit Mitte der 70er Jahre die Lage auf dem Arbeitsmarkt dra…

Synthesis and characterization of mono- and binuclear copper(II) complexes with 2,2′:6′,2″-terpyridine (terpy) and carboxylates: X-ray crystal struct…
1987
Abstract Perchlorate and hexafluorophosphate salts of monomeric [Cu(terpy)(OOCH)(OH2)]+ and dimeric [Cu(terpy)(OOCR)]22+ cations (terpy = 2,2′:6′,2″-terpyridine, R = CH3 or C2H5) have been synthesized and characterized by IR, electronic and ESR spectra, and analytical data. Spectroscopic results indicate a five-coordinate, close-to-square pyramidal geometry around the copper(II) ion. The half-field absorption in the ΔMs = 2 region of powdered X-band ESR spectra has been observed for the dimeric species. The crystal structure of [Cu(terpy)(OOCH)(OH2)](ClO4) has been determined by X-ray diffraction methods. The compound crystallizes in the space group P21/c with unit-cell dimensions: a = 7.34…
Two proteases from nuclei of rat testis cells. I. Isolation
1987
Abstract Two proteases, assayed with fluorogenic peptides and tentatively designated Rc and Kc, have been isolated from nuclei of rat testis cells by differential extraction with acetic acid, removal of some proteins at pH 4.5, and polyacrylamide gel electrophoresis followed by electroblotting onto nitrocellulose paper. Protease R hydrolyzes t‐Butyl‐oxycarbonyl‐Val‐Pro‐Arg‐7‐amino‐4‐methyl‐coumarin and other peptides in which arginine is joined to 7‐amino‐4‐methyl‐coumarin by amide linkage. Protease Kc has a preference for peptides terminating in lysine‐7‐amino‐4‐methylcoumarin amide. Neither of these proteases is active against Glu‐Phe‐7‐amino‐4‐methyl‐coumarin amide or Carbobenzoxy‐Arg‐7‐…

El debat pro i antifeminista a la literatura catalana medieval
1987
This 1987 PhD dissertation, was de facto supervised by professors Lola Badia (Universitat de Barcelona) and Alan Deyermond (Queen Mary University of London), although, because of legal limitations at that time, supervision was officially signed by another professor). This was a pioneer work in the field of women’s studies, particularly in the so-called “querelle des femmes”, although, as the dissertation study specifies, this label would only become known as such in post-medieval times. This work, then, does not deal with all misogynistic references in the whole corpus of medieval Catalan literature (that would be quite impossible in one publication), but only with those texts arguing for o…

The material of this study has been collected from the South-Western Mediterranean in the course of two expeditions by the Italian Research Vessel “Bannock”. The primary collection method employed was SCUBA diving. The sampled area is affected by an important inflow of water from the Atlantic. Fifty-nine species have been studied. One of them, Stylostichon equiosculatus, is new to science. Some ecological considerations are also discussed.
