marginal zone lymphoma (mzl) accounts for between 5% and 17% of all non-hodgkin lymphomas (nhl). w e reported a rare case of marginal zone lymphoma presenting with bilateral ear erythema and swelling. the case was a 79-year-old man who suffered from progressive bilateral ear erythema and swelling since 2 years ago. physical examination was remarkable for erythmatous, edematous and non-tender au...

tourmaline can be found as an accessory mineral in a variety of rocks including leucogranite, pegmatite, quartz veins, and metamorphiccountry rocks in hajiabad-dehgah area in se of boroujerd city. tourmaline in pegmatites is coarse-grained, subhedral to euhedral, anddisplays strong to moderate pleochroic blue rimmed by olive green. in contrast, tourmalines from leucogranite, quartz-veins, and h...

in order to study of biostratigraphy and age dating of kazhdumi formation, based on planktonic foraminifera and correlation of identified biozones with global standard biozones, this formation at tang-e-maghar have been studied. in this study 73 samples of kazhdumi formation, with 270 meter thickness, have been collected. the main lithological units at the studied section consist of the black b...

The exclusion zone (EZ) is a boundary region devoid of macromolecules and microscopic particles formed spontaneously in the vicinity of hydrophilic surfaces. The exact mechanisms behind this remarkable phenomenon are still not fully understood and are debated. We measured the shortand long-time-scale kinetics of EZ formation around a Nafion gel embedded in specially designed microfluidic device...

In this paper, we propose a method in order to compensate contortion of page image which is caused by photographing a book opened and placed face-up (two pages opposite each other state) on the stage just above. For compensating contortion 3-D shape information of page surface is necessary to apply some geometrical adjustment. To obtain much higher resolution image a page needs to be photograph...

This paper is aimed at introducing a new approach to estimate the density of Brown Plant Hoppers (BPHs) at provincial scale. The model is based on the topology of a light-traps network (to gather the information about the BPHs) of a province. The BPHs density is determined based on Unit Disk Graph technique where each light-trap becomes a vertex and the edges reflect the relations on the mutual...

A theorem of Lovv asz asserts that (H)== (H) r=2 for every r-partite hy-pergraph H (where and denote the covering number and fractional covering number respectively). Here it is shown that the same upper bound is valid for a more general class of hypergraphs: those which admit a partition (V 1 ; : : : ; V k) of the vertex set and a partition p 1 + +p k of r such that je\V i j p i r=2 for every ...
