Esperienza ed evento della verità. Pratica filosofica e astrazione scientifica nel pensiero di A.N. Whitehead
No full textThis article analyzes the relationship between philosophy, experience and event in A.N. Whitehead’s thought. From the critics of the concept of object, the author retraces and describes the peculiar “abstract-concrete dialectic”, at the center of the researches concerning the perceptual experience.
Furthermore, according to Whitehead’s later works, she demonstrates how the philosophical practice is different from all other kinds of science, although it requires science itself because of the co-implication of object and event, abstraction and recognition
Il "Guerrin Meschino" di Gesualdo Bufalino : un'"opra" in versi
No full textGesualdo Bufalino first published Il Guerrin Meschino in 1991 in a non-commercial edition. In 1993, after a deep revision, he re-published his work with publisher Bompiani: the novel has a modified plot, and the author decided to insert three new poems in addition to the opening and closing poems, formerly present in 1991’s edition. This paper, in its entirety supported by handwritten material preserved at Fondazione Gesualdo Bufalino (Comiso), is divided in two parts: the first part illustrates the differences between the first and the second edition, the second part provides a critical edition of the five poems
A FEW WORDS ABOUT THE TEACHER. IN MEMORY OF THE EXCELLENT TEACHER AND SCIENTIST M.R. SAPIN
No full textM.R. Sapin (1925–2015) was a professor at I.M. Sechenov First Moscow State Medical University, honorary academician of Russian academy of medical sciences (1988), and an outstanding representative of the Moscow anatomical school of the middle of XX – early XXI century. From the very beginning of his medical training, Mikhail Romanovich got interested in anatomy, especially in angiology and lymphology, and later concentrated on its studying. The author of more than 30 text books and guidelines for schools, universities, and colleges, Mikhail Romanovich was the doctoral and thesis advisor of 51 Ph.D. and approximately 70 MD dissertations. M.R. Sapin made a significant contribution to the development of anatomical education providing the departments with a various range of dry and wet specimens. His stunning and effective work as a tutor was highly appreciated by his students and colleagues, Russian and foreign anatomists. M.R. Sapin was the leader of the Laboratory of Functional Anatomy since 1972, president of the International Association of Morphologists (1992–2006), chairman of the expert commission of Higher Attestation Commission (1959–1994), etc. A man of a great willpower, M.R. Sapin faced a lot of obstacles in his life and research work but overcame that all successfully. The article presents the most important facts of anatomist’s career and lifetime.</jats:p
Verslag van het voorgevallene tijdens het hooge opperwater op de Nederlandsche rivieren in den winter van 1919 op 1920
No full textNadat de Rijn op 20 December 1919 tot even beneden den middelbaren zomerstand 1901-1910 (M.R.) was gedaald vertoonde zich op die rivier een sterke en vrij snelle was, waardoor het water te Keulen tot 6m +M.R. bij het einde van het jaar steeg. In de daarop volgende 11 dagen daalde de waterstand tot 1.5m +M.R. om daarna in 5 dagen weder te rijzen tot den zeer hoogen stand van 7m +M.R. Door een aanvankelijk sterken later flauweren val liep de stand weder terug tot 1.5m +M.R. op 30 Januari. Ook op de Maas vertoonden zich twee dicht op elkaar volgende sterke wassen. Bij den aanvang van den eersten was op 19 december stond het water te Maastricht op ruim 1m +M.R. en steeg het in 6 dagen tot 4.37m +M.R.; in de daaropvolgende 9 dagen bleef de stand steeds hoger dan 4m +M.R. en daalde toen tot ongeveer 2m +M.R. op 10 Januari 1920. De tweede was trad op laatsgenoemde datum in waarbij het water oplied tot 4.94m +M.R. op 15 Januari. Het water daalde daarna dadelijk en was op 29 Januari tot ongeveer 2m +M.R. weggevallen. Bij den tweeden was op Rijn en Maas werden de hoogst bekende waterstanden bij open rivieren overtroffen te Keulen met 7 cm en te Maastricht met 2 cm. De rivieren waren ijsvrij.Hoogwaterversla
Monilearia (Lyrula) tubaeformis Alonso & Groh, sp. nov.
No full textMonilearia (Lyrula) tubaeformis Alonso & Groh, sp. nov. Type locality. Lomo del Aceituno, Fuerteventura (UTM: 28 RES 8839, 350 m altitude). Holotype. TFMC (MT 0390); leg. M.R. Alonso and M. Ibáñez, 30 Dec 1993. Paratypes. 127 paratypes (56 ethanol specimens and 71 shells, collected between 1987 and 2004), CGH (42 paratypes), CKW (38 paratypes) and AIT (47 paratypes). Etymology. The name tubaeformis refers to the shell form, resembling a bugle. Distribution and habitat (Fig. 1). The species is endemic to Fuerteventura. It occurs at an altitude of 300–600 m, in dry open areas of arid subtropical shrub and small ravines, mostly with Euphorbia balsamifera Aiton, 1789, mainly under stones. Description. Soft body brownish, the dorsum moderately darker than the sides. Shell (Table 2; Fig. 3 G) with a flat or even sunken spire, and with a twice significantly angulated periphery. It embraces about 3 ½ whorls, separated by an only slightly impressed suture. The umbilicus is eccentric, deep and very wide. The last quarter of the bodywhorl descends considerably in respect to the prior quarter, the last part becoming completely separated from the coil, being bended down — and outwards and widened a bit (approx. 0.2–0.25 mm), resembling the bell of a tuba and showing some variability in its length and inclination (Fig. 4). The aperture is well rounded, only with a small angulation in its outer edge. The peristome is free, its edges all around slightly reflected, forming a narrow white lip approximately 0.25 mm wide. The peculiar ornamentation of the teleoconch is of the Lyrula type (Fig. 3 H) but very much developed, being stronger at the lateral and ventral parts of the shell. At the dorsum it is formed by numerous fine radial riblets which bear in regular intervals raised glossy lobulations which are placed such that they give the appearance of 5–6 spiral costulations that form a reticulation with the radial riblets. The lateral and ventral part exhibits 8–9 significant spiral lobulated ribs, which are not interrupted by the radial riblets; in the contact zone between a spiral rib and each two radial riblets, a nodule is differentiated (Fig. 3 H). Additionally, between each two contiguous spiral ribs there are several fine, regular spiral riblets which are crossed by the radial riblets. The protoconch is slightly prominent, brown, with 1 – 1 ¼ whorls, initially smooth (approximately ¼–½ whorls) and its distal part bearing fine radial riblets. The teleoconch is coloured light brown, patterned with narrow, darker, irregular radial flames. FIGURE 5. Drawings of genital systems. A. Monilearia tubaeformis sp. nov., paratype from Vega de Río Palmas; B–C. Monilearia multipunctata; from Casas de Ugán; C. genital system with the distal male duct duplicated; A 1 –A 5, parts of the vaginal stimulator appendix (terminology after Schileyko, 1984: 39, fig. 18); a, atrium; bc, bursa copulatrix; e, epiphallus; f, flagellum; p, penis; r, retractor muscle; sp, spermoviduct. The kidney measures less than half of the lung length; secondary ureter extremely short, almost absent. Genital system (Fig. 5 A; 3 specimens dissected): Atrium similar in length to distal male duct (between atrium and penis retractor muscle insertion), which measures about ½ of the length of the proximal portion of the epiphallus and ½ than that of the flagellum. The penis retractor muscle inserts at the epiphallus. The penis is slightly widened. The vagina is very short, its diameter similar to that of the free oviduct. The duct of the bursa copulatrix is long. The branched glandular portion (A 5) of the vaginal stimulator appendix is split into two digitlike, thin ducts that are slightly longer than the A 4 portion. Remarks. The special shell ornamentation of M. tubaeformis and M. multipunctata is of the same type as that of Helix loweana, being a synapomorphy of these species. Because of this, the three species are placed in the supraspecific taxon Lyrula. The genital system of M. tubaeformis and M. multipunctata is of the same type as that of M. phalerata and M. inops, indicating that Lyrula is a subgenus of the genus Monilearia, whose phylogenetic relationships within the family Cochlicellidae were recently established (Ibáñez et al. 2003). M. tubaeformis is a species unambiguously different from all of the other Cochlicellidae species because of its very distinctive shell characters. It is less adapted to the driest conditions than M. multipunctata, which also colonized the Jandía Peninsula (Fig. 1). M. tubaeformis lives at a higher altitude, with more environmental humidity. It has been unable to cross the desertlike barrier of sand dunes occupying the isthmus of the Jandía Peninsula (“El Jable”) to colonize the South of the island.Published as part of Ibáñez, Miguel, Groh, Klaus, Alonso, María R. & Castillo, Carolina, 2006, The subgenus Monilearia (Lyrula) Wollaston, 1878 (Gastropoda: Helicoidea: Cochlicellidae) from Lanzarote and Fuerteventura (Canary Islands), with the description of Monilearia (Lyrula) tubaeformis sp. nov., pp. 29-41 in Zootaxa 1320 on pages 37-39, DOI: 10.5281/zenodo.17400
Hemicycla (Hemicycla) laurijona Alonso & Ibáñez, 2007, sp. nov.
No full textHemicycla (Hemicycla) laurijona sp. nov. Type locality. Barranco de Aramaqué, La Gomera (UTM: 28 R BS 8114, 1000 m altitude). Holotype ( Fig. 4 A). TFMC (MT 0392); leg. M.R. Alonso and M. Ibáñez, 15 th February 1985. Paratypes. 45 paratypes collected between 1985 and 2006 (14 specimens, bodies preserved in ethanol and 31 shells): CHC (7 paratypes: 6 specimens, bodies preserved in ethanol, and 1 shell); TFMC (1 paratype: MT 0393) and AIT. Etymology. The name “ laurijona ” is a combination of the first five letters of the Spanish term “laurisilva” (= laurel forest) and the first four letters of the name “Jonay”, the lover of Gara (The Garajonay National Park, in La Gomera, is named after both mythical lovers.). Distribution and habitat (Fig. 1). The species is endemic to La Gomera. It occurs at an altitude of 700– 1280 m in the National Park of Garajonay and its surroundings. The live specimens (Fig. 3 A) were mainly found under moss on the trunks of trees in the laurel forest. Description. Body dark-brown coloured, sole pale-brown. The shell (Table 2; Figs. 2 A, 3 A, 4 A,B, 5 A–C) is imperforate, slightly depressed globular, with 3 ¾– 4 ¼ low convex whorls and shallow sutures. The aperture is oblique, without angulations and rounded in the palatal zone. The white peristome is only slightly reflected in a lip in the palatal zone, whereas it is well reflected in the columellar zone, covering the umbilicus. The shell has a small, weak and wide radial costulation combined in the body whorl, with an also weak malleate surface sculpture. The shell surface is glossy, brilliant, with highly variable colouring. Some specimens are pale-brown, others dark brown; some are uniform, slightly reddish and others pale greenish coloured. In some specimens there are four, in others five spiral, darker bands: two-three dorsal bands narrow or wide, sometimes interrupted, and two ventral narrower and more uniform. In many specimens, all the bands are interrupted, forming irregular patches that fuse with those of the neighbouring bands, giving the shell a multicoloured appearance. Genital system (Fig. 6 A–C; 3 specimens dissected): Atrium short. The bursa copulatrix complex in the female genital system shows a moderately short diverticulum, slightly longer than the bursa copulatrix duct. The latter is slightly shorter than the common stalk and slightly swollen distally, shortly before entering the proximal vagina. The bursa copulatrix is rather small and globular, with its neck inserted into the diaphragm. The dart sac is accompanied by a pair of branched tubular mucus glands. The male portion of the genital system shows a penial complex with a very long flagellum, about 4–5 times longer than the distal male duct (i. e. that part of the penial complex between the retractor muscle insertion and the atrium). The penis sheath is very thin, translucent and poorly visible. The retractor muscle has an epiphallar insertion. The length proportions between the above mentioned male and female ducts are similar to those of the immature specimen shown in Fig. 6 B. The penis has a system of twin papillae with a penial chamber between them (Fig. 6 C). The penial chamber has pleated walls and is in fact the chamber of the distal penial papilla. The connection between the distal penial papilla and the penis wall is sometimes visible from the exterior (Fig. 6 B) and we named it as the “ring zone”. A well developed contact organ is located between the distal penial papilla and the atrium. Remarks. The species most similar to H. laurijona in shell shape and shell dimensions is H. perraudierei (Figs. 4 C, 5 D–F) from El Hierro, the westernmost, youngest and smallest island of the archipelago, about 60 km distant from La Gomera. H. laurijona generally has a slightly smaller and more depressed shell than H. perraudierei (Figs. 4,5,7), and also a weaker shell malleation (Fig. 5), but the main morphological difference between both species is found in the female part of the genital organs, namely in the length of the stalk of the bursa copulatrix complex. The stalk in H. laurijona is, in fact, similar in length to that of the bursa copulatrix duct and of the diverticulum (Fig. 6 A,B), whereas in H. perraudierei it is nearly twice as long (Fig. 6 D,E). Both species also differ in their microhabitat. H. laurijona lives under moss on the tree trunks in the laurel forest of La Gomera, whereas H. perraudierei was found at a similar altitude (600–1100 m), in the upper area of the degraded laurel forests of El Golfo and Tiñor (El Hierro), among the leaves of Aeonium sp. and also among fallen dead leaves.Published as part of Alonso, María R. & Ibáñez, Miguel, 2007, Anatomy and function of the penial twin papillae system of the Helicinae (Gastropoda: Helicoidea: Helicidae) and description of two new, small Hemicycla species from the laurel forest of the Canary Islands, pp. 1-23 in Zootaxa 1482 on pages 6-9, DOI: 10.5281/zenodo.17689
