The purpose of this paper is to propose an efficient method to compute the automorphism group of an arbitrary hyperelliptic function field over a given ground field of characteristic > 2 as well as over its algebraic extensions. Beside theoretical applications, knowing the automorphism group of a hyperelliptic function field also is useful in cryptography: The Jacobians of hyperelliptic curves ...

Cranial nerve blocks (CNBs) have been used for the acute and preventive treatment of a variety headaches, including migraine. The effectiveness CNBs in migraine is usually observed beyond duration block, possibly due to central pain modulation. most target greater occipital nerve. Other commonly targeted nerves are lesser various branches trigeminal nerve, supratrochlear, supraorbital, auriculo...

DACRYOCYSTORHINOSTOMY, the operation of choice in chronic dacryocystitis, is performed in almost all cases in this clinic by a special technique. Toti (1904) first described the drainage of the lacrimal sac by removal of the bony wall. Kuhnt (1914) stitched the nasal mucosa to the periosteum. Ohn (1920) first sutured the nasal mucosa to the sac. The operation was modified by Dupuy-Dutemps and B...

BACKGROUND/AIM Chronic migraine is a common debilitating disease with limited treatment options. We aimed to develop a novel model for chronic migraine by ligating the nasociliary nerve (NCL) and administering nitroglycerin (NTG) to exacerbate acute headache attacks. MATERIALS AND METHODS Exacerbation of the headache was induced by NTG (10 mg/kg, subcutaneously) administered to male Wistar ra...

The genus Chalcasthenes Arrow (Dynastinae: Oryctoderini), a scarab beetle genus endemic to the Solomon Islands, is reviewed. Based on examination of type specimens, the genus Strehlia Frey (Rutelinae: Rutelini: Parastasiina) is a new junior synonym of Chalcasthenes. The historical classification of these genera (either in the subfamily Dynastinae or Rutelinae) and character-based criteria for a...

OBJECTIVE To measure patient-reported quality of life before and after botulinum toxin A treatment of post-parotidectomy Frey's syndrome (gustatory sweating). PATIENTS AND METHODS A questionnaire concerning functional, social and emotional aspects of Frey's syndrome (14 questions, with responses on a zero to three point scale) was administered to 17 patients (13 women and four men) before and...

Frey and Kani put a particular modular space structure on the space of a space of modular curves that resembles a Hurwitz space structure. We follow up on this, simplifying the group theory so that properties of this space are clear. For the rst, Prop. 2.4 shows it is simple to characterize the monodromy group of Frey-Kani covers of degree N (and that it is S N). In anticipation of other proble...

At maturity the companion cell of the phloem of the sycamore Acer pseudoplatanus has a large nucleus, simple plastids closely sheathed with rough endoplasmic reticulum, and numerous mitochondria. The cytoplasm contains numerous ribosomes, resulting in a very electron-opaque cytoplasm after permanganate fixation. Bodies similar to the spherosomes of Frey-Wyssling et al. (4) are collected in clus...
