Abyssomelania Kaim, Jenkins, Tanabe & Kiel, 2014, gen. nov.
No full textGenus Abyssomelania gen. nov. Type species. Abyssomelania cramptoni sp. nov.; Campanian (Late Cretaceous), from seep limestones found at Waipiro Bay, North Island, New Zealand (see Kiel et al. 2013). Diagnosis. Large, high-spired shell with abyssochrysoid early teleoconch whorls (reticulate with dominant axial ribs) and adolescent/adult whorls smooth apart from opisthocline growth lines and unusual widely-spaced prosocline riblets (named here abyssomelanid riblets) manifested only on abapical portion of the flank. Species included: The type species and A. campbellae sp. nov. Remarks. Abyssomelania is most similar to Ascheria gen. nov. described below but it differs by having the greatest whorl width at the adapical suture and lacking a subsutural constriction. Abyssochrysos Tomlin, 1927 is usually smaller and more slender and has axial ribs present throughout the ontogeny. Humtulipsia Kiel, 2008 differs by having a deep notch near the basal margin. None of these genera possess the prosocline abyssomelanid riblets. Etymology. Abysso - referring to deep water occurrences and – melania to express the gross melaniform shell shape. Stratigraphic range. Albian (Early Cretaceous) to Campanian (Late Cretaceous).Published as part of Kaim, Andrzej, Jenkins, Robert G., Tanabe, Kazushige & Kiel, Steffen, 2014, Mollusks from late Mesozoic seep deposits, chiefly in California, pp. 401-440 in Zootaxa 3861 (5) on page 414, DOI: 10.11646/zootaxa.3861.5.1, http://zenodo.org/record/25246
Gen Ed /
No full text"Gen Ed locates serious discussion of general education in the context of some of the day-to-day realities encountered in putting it into practice and promoting efforts at reform at Metropolitan Atlantic University (aka the Metro). This dual focus is found in the often-pugnacious policy debate among the faculty and a more light-hearted discussion of related questions carried on by Professor Kelly as he models Socratic teaching in his upper-level class for prospective teachers. Reforming general education at the Metro is not free of the vanities and vulgarities of ambitious men and women and self-serving politicians, of course, nor those who poke fun at them. Arnie Smatter, the irrepressible and nosey chat show host of Radio YOY ensures that this does not go unnoticed. The overall humorous tone of Gen Ed does not detract from Mulcahy's thoughtful treatment of substantive issues that will be of interest to serious scholars, students, and a general readership. It is the behaviour of those involved, the broader media and political contexts in which events take place, which mainly becomes the object of humorous treatment"--Includes bibliographical references and index.Preface -- Acknowledgements -- Chapter 1 -- Chapter 2 -- Chapter 3 -- Chapter 4 -- Chapter 5 -- Chapter 6 -- Chapter 7 -- Chapter 8 -- Chapter 9 -- Chapter 10 -- Chapter 11 -- Chapter 12 -- Chapter 13 -- Chapter 14 -- Chapter 15 -- Chapter 16 -- Chapter 17 -- Chapter 18 -- Chapter 19 -- Chapter 20 -- Appendix: Questions for Discussion, Suggested Topics for Term Papers and Research Projects -- References -- About the Author."Gen Ed locates serious discussion of general education in the context of some of the day-to-day realities encountered in putting it into practice and promoting efforts at reform at Metropolitan Atlantic University (aka the Metro).

Ascheria Kaim, Jenkins, Tanabe & Kiel, 2014, gen. nov.
No full textGenus Ascheria gen. nov. Type species. Abyssochrysos ? giganteum Kiel et al., 2008 b (see Fig. 7 E–F herein) from a seep deposit on the east shore of Lake Berryessa in Napa County, California, USA; Early Cretaceous, Great Valley Group. This is locality # 12 in Kiel et al. (2008 b) and was named East Berryessa therein. Diagnosis. Large high-spired cerithiform shell with strong opisthocline axial ribs, numerous spiral lirae, and subsutural constriction developing on the adult portion of the shell. Ornament may remain throughout the ontogeny or may fade away on the adult whorls. Species included: Abyssochrysos ? giganteum Kiel et al., 2008 b from the Early Cretaceous of East Berryessa, California; Chemnitzia eucosmeta Ascher, 1906 from the Early Cretaceous of Hradiště (previously Grodischt) and Koňákov (previously Koniakau), Czech Republic; and undescribed new species from the Eocene of Barbados identified as Diastoma sp. and "Cerithid indet." by Kugler et al. (1984). The same specimens were later reillustrated and identified as “ Abyssochryssos sp.” by Gill et al. (2005: fig. 5 D) and as “zygopleurid sp. B” (Gill et al. 2005: fig. 5 F, H, I). Remarks. Ascheria differs from Abyssomelania gen. nov. described above by having evenly convex whorls, axial and spiral ornamentation throughout the ontogeny, and by the presence of a subsutural constriction. Furthermore, Ascheria lacks abyssomelanid riblets. Abyssochrysos Tomlin, 1927 differs by lacking a subsutural constriction. Humtulipsia Kiel, 2008 differs by having a deep notch in the aperture near the basal margin. Etymology. In honor of Else Ascher who monographed the Early Cretaceous seep faunas from the Český Těšín area (Ascher 1906). Stratigraphic range. Early Cretaceous to late Eocene.Published as part of Kaim, Andrzej, Jenkins, Robert G., Tanabe, Kazushige & Kiel, Steffen, 2014, Mollusks from late Mesozoic seep deposits, chiefly in California, pp. 401-440 in Zootaxa 3861 (5) on page 416, DOI: 10.11646/zootaxa.3861.5.1, http://zenodo.org/record/25246

Jacob of Sarug's Homily on Tamar (Gen 38)
No full textThis small volume contains an edition (from Vatican ms. 117) of Jacob of Sarug’s homily on Tamar (420 lines long). The full title is “On Tamar and on the Mystery of the Church.” The biblical narrative on which the poem is based (Gen 38) gives Jacob the opportunity to discuss various women in the early part of biblical history and in Jesus’ lineage, as well as the fact that a woman who is called a prostitute is in that lineage. Jacob explains how Scripture’s language is used in this regard

Mollusks from late Mesozoic seep deposits, chiefly in California
No full textTwenty-nine mollusk species from Late Jurassic to Eocene hydrocarbon seep deposits from California ( USA), Japan, New Zealand, and Barbados are described and illustrated. Twenty species belong to Gastropoda and nine to Bivalvia. Seven new species, three new genera, and one new family are introduced. The gastropod Hikidea gen. nov. includes smooth-shelled Cantrainea-like colloniins from Cretaceous hydrocarbon seeps and plesiosaur falls. Hikidea osoensis sp. nov. is the oldest species of this genus. Chilodonta? reticulata sp. nov. is a distinctive vetigastropod though its supraspecific position is unclear. Phanerolepida onoensis sp. nov. is the first species of this colloniin genus from a seep deposit. We describe two new genera of Hokkaidoconchidae: Abyssomelania gen. nov. and Ascheria gen. nov.; this family includes now four genera (including Hokkaidoconcha and Humptulipsia) and ranges from the Late Jurassic to the Eocene. Abyssomelania is characterized by a large, high-spired shell and unusual widely-spaced prosocline riblets (here called abyssomelaniid riblets). Abyssomelania is represented by two new species: A. cramptoni sp. nov. from the Late Cretaceous of New Zealand and A. campbellae sp. nov. from the Early Cretaceous of California. Ascheria gen. nov. is characterized by a large high-spired cerithiform shell, a subsutural constriction, and mostly reticulate ornament. Two nominate species are included: Ascheria gigantea (Kiel et al., 2008) and A. eucosmeta (Ascher, 1906), both of Early Cretaceous age. Two further species potentially belonging to Ascheria from the Eocene of Barbados are reported in open nomenclature and are re-illustrated and re-described for comparison. Humtulipsia nobuharai sp. nov. is described based on specimens from the Campanian-Maastrichtian Sada Limestone seep deposit in Japan. The new family Paskentanidae fam. nov. is introduced for the genera Paskentana and Atresius. The species of this family are characterized by thin-shelled, broad to high-spired littoriniform adult shells and juvenile teleoconchs with a subsutural ramp. Paskentana hamiltonensis sp. nov. is described from the Early Cretaceous of California. Ataphrus is considered to represent a nomen dubium because its type species is poorly preserved and there are uncertainties regarding its type locality and age. The bivalves reported herein belong to known species, but our new material revealed additional characters, and/or their supraspecific position is revised and new combinations are proposed: Solemya stantoni Vokes, 1955 is transferred to Acharax, Nucula gabbi Stanton, 1895 is transferred to Leionucula, Pecten complexicostata Gabb, 1869 is transferred to Lyriochlamys, Astarte californica Stanton, 1895 is transferred to Neocrassina, Astarte trapezoidalis Stanton, 1895 is transferred to Oxyeurax, and Corbula? persulcata Stanton, 1895 is transferred to Cuspidaria

The roles of the subunits in the function of the calcium channel
No full textDihydropyridine-sensitive voltage-dependent L-type calcium channels are critical to excitation-secretion and excitation-contraction coupling. The channel molecule is a complex of the main, pore-forming subunit alpha 1 and four additional subunits: alpha 2, delta, beta, and gamma (alpha 2 and delta are encoded by a single messenger RNA). The alpha 1 subunit messenger RNA alone directs expression of functional calcium channels in Xenopus oocytes, and coexpression of the alpha 2/delta and beta subunits enhances the amplitude of the current. The alpha 2, delta, and gamma subunits also have pronounced effects on its macroscopic characteristics, such as kinetics, voltage dependence of activation and inactivation, and enhancement by a dihydropyridine agonist. In some cases, specific modulatory functions can be assigned to individual subunits, whereas in other cases the different subunits appear to act in concert to modulate the properties of the channel
