Nodular Lesion in Cheek With a Hair Tuft
2017
Trichostasis spinulosa is a rarely diagnosed disorder of the pilosebaceous unit, characterized by retention of telogen hairs within the dilated follicles. A hair tuft can be seen protruding from the follicles. We present a case of trichostasis spinulosa associated with intradermal melanocytic nevi, where dermoscopy helps to identify this entity.

Animal rennets as sources of dairy lactic acid bacteria
2014
ABSTRACT The microbial composition of artisan and industrial animal rennet pastes was studied by using both culture-dependent and -independent approaches. Pyrosequencing targeting the 16S rRNA gene allowed to identify 361 operational taxonomic units (OTUs) to the genus/species level. Among lactic acid bacteria (LAB), Streptococcus thermophilus and some lactobacilli, mainly Lactobacillus crispatus and Lactobacillus reuteri , were the most abundant species, with differences among the samples. Twelve groups of microorganisms were targeted by viable plate counts revealing a dominance of mesophilic cocci. All rennets were able to acidify ultrahigh-temperature-processed (UHT) milk as shown by pH …
Guiding Student Thinking Through Teacher Questioning When Learning with Dynamic Representations
2021
Dynamic representations (e.g., dynamic geometry software GeoGebra for mathematics learning and PhET simulations for science learning) offer excellent opportunities for students to conduct investigations and to formulate explanations for the visualized phenomena. In order for this to be effective, students need guidance, for example, for planning their investigations and reflecting on their actions. One way to support students is by prompting them by using questions that are adapted to the students’ current situation. This chapter focuses on how pre-service teachers provide guidance for students through questioning and by both structuring and problematizing student learning. Data comes from …
Calls of the Jungle Crow (Corvus macrorhynchos s.l.) as a taxonomic character
2000
A discriminant analysis of the call structure completely separates threeCorvus taxa (levaillantii andjaponensis of the ‘macrorhynchos group’,splendens) inhabiting the southern slopes of the Himalayas (Nepal, Kashmir). The acoustic differences are considered taxonomically relevant, indicating species boundaries. Therefore the Jungle Crows of lower and upper Nepal (contact zone at around 2,000 m) are assigned to two biospecies (C. japonensis andC. levaillantii), as is consistent with morphological, ecological and parasitological data. It appears possible to extrapolate the findings regarding call structure to the systematics of other ‘macrorhynchos’ populations as distant as the Russian Far E…
Verkkosivustojen omaksumiseen vaikuttavat tekijät
2016
Tässä tutkielma käsiteltiin verkkosivustojen omaksumista ja siihen vaikuttavia tekijöitä. Tutkielmassa tutustuttiin aluksi teknologian omaksumiseen yleisellä tasolla, ja syvennyttiin sitten tarkemmin verkkosivustoihin. Teoreettinen tausta pohjautui teknologian omaksumisen malliin (Technology Acceptance Model, TAM), joka esittää, että kaksi tärkeintä teknologian omaksumista selittävää teki-jää ovat käyttäjän kokema hyödyllisyys ja helppokäyttöisyys. Teknologian omaksumisen tutkimus on olennaista teknologian suunnitteluprosessissa, sillä ymmärrys siihen vaikuttavista tekijöistä voi helpottaa suunnittelijoita kehittämään helpommin hyödyllisiksi ja helppokäyttöisiksi koettuja tuotteita ja palve…
A temperature-type model for describing the relationship between fungal growth and water activity
2001
Growth of Penicillium chrysogenum, Aspergillus flavus, Cladosporium cladosporioides and Alternaria alternata at their respective optimum temperatures was studied in Potato Dextrose Agar (PDA) medium at different water activities (a(w)) adjusted with glycerol. The growth rate (mu) was expressed as the increase in colony radius per unit of time. This paper extends the model that showed the relationship between temperature and bacterial growth rate developed by Rosso et al. [J. Theor. Biol. 162 (1993) 447] to describe the influence of a(w) on fungal development. An excellent correlation between the experimental data and the model predictions was obtained, the regression coefficients (r2) were …
Conjectures regarding Thalelaios' commentary on the Novus Codex
2014
Il contributo rinviene tracce di un precedente strato del commentario di Taleleo al codex repetitae praelectionis riferibile al Novus Codex Iustinianus. The paper find traces of a previous state of the Thalelaos' commentary on the codex repetitae praelectionis attributable to Novus Codex Justinian.
Upper thoracic-spine disc degeneration in patients with cervical pain.
2003
To study the relationship of upper thoracic spine degenerative disc contour changes on MR imaging in patients with neck pain. The relation between upper thoracic and cervical spine degenerative disc disease is not well established.One hundred and fifty-six patients referred with cervical pain were studied. There were 73 women and 77 men with a mean age of 48.6 +/- 14.6 years (range, 19 to 83 years). All MR studies were performed with a large 23-cm FOV covering at least from the body of T4 to the clivus. Discs were coded as normal, protrusion/bulge or extrusion.Degenerative thoracic disc contour changes were observed in 13.4% of patients with cervical pain. T2-3 was the most commonly affecte…
