The toxicity of methylmercury (MeHg) in humans is well established and the main source of exposure is via the consumption of large marine fish and mammals. Of particular concern are the potential neurodevelopmental effects of early life exposure to low-​levels of MeHg. Therefore, it is important that pregnant women, children and women of childbearing age are, as far as possible, protected from MeHg exposure. Within the European project DEMOCOPHES, we have analyzed mercury (Hg) in hair in 1799 mother-​child pairs from 17 European countries using a strictly harmonized protocol for mercury anal. Parallel, harmonized questionnaires on dietary habits provided information on consumption patterns of fish and marine products. After hierarchical cluster anal. of consumption habits of the mother-​child pairs, the DEMOCOPHES cohort can be classified into two branches of approx. similar size: one with high fish consumption (H) and another with low consumption (L)​. All countries have representatives in both branches, but Belgium, Denmark, Spain, Portugal and Sweden have twice as many or more mother-​child pairs in H than in L. For Switzerland, Czech Republic, Hungary, Poland, Romania, Slovenia and Slovakia the situation is the opposite, with more representatives in L than H. There is a strong correlation (r=0.72) in hair mercury concn. between the mother and child in the same family, which indicates that they have a similar exposure situation. The clustering of mother-​child pairs on basis of their fish consumption revealed some interesting patterns. One is that for the same sea fish consumption, other food items of marine origin, like seafood products or shellfish contribute significantly to the mercury levels in hair. We conclude that addnl. studies are needed to assess and quantify exposure to mercury from seafood products, in particular. The cluster anal. also showed that 95​% of mothers who consume once per wk fish only, and no other marine products, have mercury levels 0.55 μg​/g. Thus, the 95th percentile of the distribution in this group is only around half the US-​EPA recommended threshold of 1 μg​/g mercury in hair. Consumption of freshwater fish played a minor role in contributing to mercury exposure in the studied cohort. The DEMOCOPHES data shows that there are significant differences in MeHg exposure across the EU and that exposure is highly correlated with consumption of fish and marine products. Fish and marine products are key components of a healthy human diet and are important both traditionally and culturally in many parts of Europe. Therefore, the communication of the potential risks of mercury exposure needs to be carefully balanced to take into account traditional and cultural values as well as the potential health benefits from fish consumption. European harmonized human biomonitoring programs provide an addnl. dimension to national HMB programs and can assist national authorities to tailor mitigation and adaptation strategies (dietary advice, risk communication, etc.) to their country's specific requirements.

The raw material used in the potter site of Talatast (Morocco) is collected from Triassic colluviums. Our study aims to characterize the mineralogical and geotechnical properties of the local clayey material before and after cooking. Our results confirm that the coarse particle size, the mineralogy of the clay fraction and the rate of fondants are suitable for the cookware material production. Defects encountered during the production are mainly related to the use of traditional ovens. Understanding the origin of the main defects could be helpful to promote the local pottery production.

Dating archaeological mortar by OSL is one of the challenging objectives leading to the chronology of ancient constructions. Single grain OSL analysis is a very convenient tool to examine the bleaching state of the series of quartz grains extracted from a mortar sample. Indeed, during the making process, sand is extracted from a sedimentary source, transported, stored then mixed with lime and set into the walls being constructed. Experience shows that incomplete bleaching is frequent for these materials. The aim of this study is to model the distribution of single grain equivalent doses of mortars following the assumption that a population of grains corresponds to a unique distribution of heterogeneously bleached grains rather than to a mixture of well bleached quartz grains with poorly bleached ones. An exponential distribution of light exposure of grains is examined. By comparing experimental distributions of doses with simulated ones, we investigate the appropriateness of this distribution function and then we calculate the average residual dose integrated into the process of the ED determination and finally the OSL age. Limits and potentials of this approach are discussed using various case-studies of structures and buildings of known age (from the roman to the post-medieval period). Even in case of very poorly bleached samples we observed that the simulated ED distribution fits satisfactorily with the experimental one, which offers new encouraging perspectives in single grain dating of mortars.

Chronic kidney disease is frequent and usually responsible of mineral and bone disorder. These abnormalities lead to increased morbidity and mortality. To become active, native vitamin D needs a first hydroxylation in the liver, and a second one in the kidney. Next to its action on bone metabolism, vitamin D also possesses pleiotropic actions on cardiovascular, immune and neurological systems as well as antineoplastic activities. End-stage renal disease (ESRD) is also associated with a decrease in vitamin D activity by mechanisms including the increase of plasma phosphate concentration, secretion of FGF- 23 and decrease in 1a-hydroxylase activity. The prevalence of 25 hydroxy-vitamin D deficiency depends on the chosen cut-off value to define this lack. Currently it is well established that a patient has to be substituted when 25 hydroxy-vitamin D level is under 30 ng/mL. The use and monitoring of 1.25 hydroxy-vitamin D is still not recommended in routine practice. The goals of vitamin D treatment in case of ESRD are to substitute the deficiency and to prevent or treat hyperparathyroidism. Interest of native vitamin D in first intention is now well demonstrated. This review article describes the vitamin D metabolism and physiology and also the treatment for vitamin D deficiency in ESRD population. [less ▲]

In this chapter, it is argued that Weber's particular combination of Von Kries' naturalistic paradigm and Rickert's antinaturalistic paradigm might become less puzzling if we return to the interpretation that emerged in the middle of the nineteen-twenties within the South-Western School of neo-Kantianism. The basic intuition which underlies this interpretation is that the social sciences are best understood as generalizing cultural sciences. On this understanding, they differ both from the natural sciences and the historical sciences. [less ▲]

We consider a mixed integer set which generalizes two well-known sets: the single node fixed- charge network set and the single arc design set. Such set arises as a relaxation of feasible sets of general mixed integer problems such as lot-sizing and network design problems. We derive several families of valid inequalities that, in particular, generalize the arc resid- ual capacity inequalities and the flow cover inequalities. For the constant capacitated case we provide an extended compact formulation and give a partial description of the convex hull in the original space which is exact under a certain condition. By lifting some basic inequalities we provide some insight on the difficulty of obtaining such a full polyhedral description for the constant capacitated case. Preliminary computational results are presented. [less ▲]
