OBJECTIVE The purpose of this study was to determine whether writing tool type and angle of writing surface affect grasp. METHOD Fifty-one children 23 to 24 months of age who were typically developing drew with a primary marker, colored pencil, and small piece of crayon on a table and an easel. The marker and pencil were presented pointing left, right, and toward the child. The order of writi...

A 14-year-old male patient had an ocular trauma with a pencil. Biomicroscopic examination revealed a broken part of pencil into the cornea. Foreign body removal and corneal wound closure were performed in the same day. After corneal repair, there was a grade 4+ anterior chamber reaction just like in preoperative examination. Dilated examination showed a very small piece broken tip of pencil on ...

The majority of scientific papers focusing on wood classification for pencil manufacturing take into account defects and visual appearance. Traditional methodologies are based on texture analysis by co-occurrence matrix, by image modeling, or by tonal measures over the plate surface. In this work, we propose to classify plates of wood without biological defects like insect holes, nodes, and cra...

A K3-surface is a (smooth) surface which is simply connected and has trivial canonical bundle. In these notes we investigate three particular pencils of K3-surfaces with maximal Picard number. More precisely the general member in each pencil has Picard number 19 and each pencil contains four surfaces with Picard number 20. These surfaces are obtained as the minimal resolution of quotients X/G, ...

Introduction: Diagnosis of orbital foreign body (FB) penetration is usually obvious when part of the FB is still attached at the entry wound (1). However, the depth and course of the FB in this case was not visible.   Case Report: A 5-year old female presented with a pencil penetrating the left orbit. A computed tomography (CT) scan showed that the pencil penetrated the left orbit (extraseptal)...

In 1985 Xiao Gang proved that the bicanonical system of a complex surface S of general type with p2(S) > 2 is not composed of a pencil ([X1]). In this note a new proof of this theorem is presented.

Beside longitudinal growth along the length, we show that ZnO nanorods also exhibit transverse growth, which is responsible for the formation of interpenetrative nanorods. The longitudinal growth is lead by the catalytically active Zn-terminated (0001) surface, while the oxygen-terminated ð000 1Þ surface is catalytically inactive, resulting in the formation of ‘pencil’ or ‘bullet’ shaped nanost...

Let X be a smooth projective surface such that linear and numerical equivalence of divisors on X coincide and let σ ⊆ |D| be a linear pencil on X with integral general fibers. A fiber of σ will be called special if either it is not integral or it has non-generic multiplicity at some of the base points (including the infinitely near ones) of the pencil. In this note we provide an algorithm to co...
