BACKGROUND Several cadaveric studies demonstrate reliable localization of the transverse sinus and the transverse sigmoid junction (TSJ). These studies use the line drawn from the inion to the posterior root of the zygoma (IZ) and the asterion, respectively. We investigated how the size difference between the right and left transverse sinuses (TS) and sigmoid sinuses (SS) affected the accuracy ...

We disclose herein the perfluoroalkylation of alkenes catalyzed by trifluoroethoxy-coated zinc phthalocyanine under irradiation of visible light. Perfluoroalkyl iodides were nicely incorporated into unsaturated substrates, including alkyne, to provide perfluoroalkyl and iodide adducts in moderate to good yields. Trifluoromethylation is also possible by trifluoromethyl iodide under the same reac...

This is a pedagogical introduction to the treatment of general relativity as a quantum effective field theory. Gravity fits nicely into the effective field theory description and forms a good quantum theory at ordinary energies. Lectures presented at the Advanced School on Effective Theories, Almunecar, Spain June 1995 (to be published in the proceedings). UMHEP424, gr-qc/9512024

The elaboration of biologically important 3,4-substituted pyrazolines was achieved by an organocatalysed aza-Michael/transimination domino sequence between hydrazones and enones making use of a mixture of heterogeneous resin-bound acid/base reagents. This methodology nicely illustrates the site isolation concept of supported reagents allowing the simultaneous use of otherwise destructive reacti...

Cancer puncture was probably in vogue for centuries. Certainly, it is recommended that the past must be kept in mind when present work is in progress. Therefore, a good example is deemed worthy of documentation, especially as it appeared nicely in the Transactions of the Pathological Society of London in 1882.

Two cases of Madelung disease (benign symmetrical lipomatosis) are presented. The MR findings in this striking condition are demonstrated. Short-repetition-time/short-echo time sequences nicely show the relationship of the cervical lipomatous accumulations to the airway and major neurovascular structures in the carotid spaces. Fat-suppression techniques add no additional information in the radi...

companies Dauphin is an international company based in germany. It has for many years operated a North American subsidiary, Dauphin North America, based in Boonton, NJ. Dauphin's traditional product fare has been nicely designed seating for a variety of applications. The company's strength is

We investigate the complexity of generalizations of colourings (acyclic colourings, (k, `)colourings, homomorphisms, and matrix partitions), for the class of transitive digraphs. Even though transitive digraphs are nicely structured, many problems are intractable, and their complexity turns out to be difficult to classify. We present some motivational results and several open problems.

The $\otimes^\star$-monoidal structure on the category of sheaves $\mathrm{Ran}$ space is not pro-nilpotent in sense Francis-Gaitsgory. However, under some connectivity assumptions, we prove that Koszul duality induces an equivalence categories and this behaves nicely with respect to Verdier integrating along space, i.e. taking factorization homology. Based ideas sketched by Gaitsgory, show the...

fullerenes are closed−cage carbon molecules formed by 12 pentagonal and n/2 – 10hexagonal faces, where n is the number of carbon atoms. patrick fowler in his lecture inmcc 2009 asked about the wiener index of fullerenes in general. in this paper werespond partially to this question for an infinite class of fullerenes with exactly 10ncarbon atoms. our method is general and can be applied to full...
