The fluting instability has been suggested as the driver of subsurface structure sunspot flux tubes. We conducted a series numerical experiments where we used tubes with different initial curvatures to study effect on spots. MURaM code, which previously simulate complete sunspots, first compute four sunspots in slab geometry and then two circular spots opposite polarities. find that curvature t...

Although the January blues1 might be familiar, this year’s context has meant that exam season been more difficult than ever. If you have taken stairs at a London tube station, may able to draw parallels between month in our third national lockdown, and feeling get as continue walk round curved staircase, thinking “surely I’m nearly there . .”, without yet being see daylight. Yet even we’re “buf...

introduction: the purpose of this in vitro study was to compare the accuracy of the new electronic apex locator raypex5 with radiography for working length determination of straight and curved root canals. materials and methods: twenty straight and single canals of maxillary central teeth and twenty curved mesiobuccal canals of mandibular molar teeth were used. access cavities were prepared and...

Aristocleidus mexicanus n. sp. and Aristocleidus lacantuni n. sp. are described from the gills of the Mexican mojarra Eugerres mexicanus (Gerreidae, Perciformes) from the Rio Lacantún basin, Chiapas State, Mexico. These new species differ from previously described congeneric species in the characteristics of several structures, including: (a) ventral anchors, with differences in length (i.e. 46...

BACKGROUND Little information is available about the accuracy of the teeth mark on the laryngeal tube (LT) as a guide to correct placement in children. The aim of this crossover study was to evaluate three methods for optimal insertion depth of the size (#) 2 tube in children weighing 12-25 kg. METHOD In 24 children, the LT #2 was consecutively inserted by three different methods: (A) until t...

Primary fallopian tube tumors, which are rare gynecological malignancies that account for 0.14%-1.8% of genital malignancy, mainly affect women aged 40-65 years [1]. Diagnosing primary fallopian tube tumors is challenging, and case reports involving tumors managed using robot-assisted staging surgery are rare. However, we have reported here two cases with favourable prognoses of primary fallopi...

tions and advantages of this method have been reported (Barber, J. MIilk & Food Technol., 12, 257-266, 1949), and it is well to point out here the obvious economy in incubator space, agar medium, time, and productivity. Usually, 4 to 5 ml of agar are used per tube. Samples (1 ml or some fraction thereof) aire added to the sterile, melted, and tempered agar; the tubes are agitated gently, slante...
