Introduction: The Jezero impact crater hosted an open-basin lake [1] that was active during the valley network forming era on early Mars [2]. This basin contains a well exposed delta deposit at the mouth of the western inlet valley (Fig. 1) [1,3-5]. The fluvial stratigraphy of this deposit provides a record of the channels that built the delta over time. Here we describe observations of the str...

Clinical and pathological examination was performed on 378 eyes from 216 patients aged 43 to 97 years. This series represented eyes in which the fundi were normal or showed various manifestations of senile macular degeneration. The eyes were divided into six groups according to the histological appearance of a linear deposit at the base of the retinal pigment cells. Groups I and II were conside...

Fibronectin was localized using peroxidase and biotin-avidin-ferritin techniques in developmental stages of the chick embryo from laying to primitive streak formation. The primary location of fibronectin at all stages examined was the basal lamina of the epiblast and its associated extracellular material. The remaining tissues showed little or no immunochemical deposit. At the primitive streak ...

Legal deposit processes for printed material has been established for centuries [1]. However, the same processes are not necessarily applicable in the case of non-print material such as electronic books. Legal deposit of electronic publications is subject to numerous, often unique challenges such as the legal deposit process, legal issues and infrastructure required. Some of these have been rep...

Measuring value and interest rate risk in retail financial markets such as the market for consumer deposits has proven to be a very difficult problem for financial firms. Standard models of value and interest rate risk (duration), based on the competitive market paradigm, are inappropriate in retail markets characterized by sluggish price and quantity behavior. Although the penetration of sophi...

Light and electron microscopic studies of corn plants (Zea mays L.) exposed to Pb in hydroponic solution showed that the roots generally accumulated a surface Pb precipitate and slowly accumulated Pb crystals in the cell walls. The root surface precipitate formed without the apparent influence of any cell organelles. In contrast, Pb taken up by roots was concentrated in dictyosome vesicles. Dic...

introduction there is an iron mining complex called shahrak 60 km east of takab town, nw iran. the exploration in the shahrak deposit (general name for all iron deposits of the area) started in 1992 by foolad saba noor co. and continued in several periods until 2008. the shahrak deposit comprising 10 ore deposits including korkora-1, korkora-2, shahrak-1, shahrak-2, shahrak-3, cheshmeh, golezar...

Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...
