An interlaboratory comparison was organised by JRC-IRMM among environmental radioactivity monitoring laboratories for the determination of gross alpha/beta activity concentration in drinking water. Independent standard methods were used for the reference value determination. The performance of participating laboratories was evaluated with respect to the reference values using relative deviation...

The determination of molecular structure is an important step in the potential applications of naturally occurring organic compounds with interesting biological activity. For a significant fraction of newly isolated natural products, however, standard analytical techniques such as Nmr and mass spectrometry cannot provide a definitive structure. Now, Leo gross and co-workers have used a scanning...

BACKGROUND Participation in regular physical activity (PA) during the early years helps children achieve healthy body weight and can substantially improve motor development, bone health, psychosocial health and cognitive development. Despite common assumptions that young children are naturally active, evidence shows that they are insufficiently active for health and developmental benefits. Expl...

Electron microscopy of hepatic tissue obtained by percutaneous needle biopsy from nine patients with Gilbert's syndrome has revealed in every case gross hypertrophy of hepatocyte agranular endoplasmic reticulum but no other important abnormality. While this may have relevance to impairment of microsomal enzyme activity controlling bilirubin conjugation within liver cells, the serum bilirubin l...

Malignancies may produce bony metastases which may be osteoclastic or osteoblastic. Vertebrae are a common site for bony metastases. Prostatic adenocarcinoma is an important source of vertebral metastases that are mainly osteoblastic in nature. As the osteoblastic metastases are developing there is an ongoing osteoclastic activity which is going on at the microscopic level. Presence of gross os...

Conclusions The results of gross malnutrition and deprivation of foodstuffs can therefore be due to some of these individual nutrient deficiencies, in so far as animal results apply to man. They can be due to other individual dietary deficiencies, they can be due to the algebraic effect of several deficiencies. Still more, of course, gross deprivation of protein and fats can be expected to caus...

A Gross space is a vector space E of infinite dimension over some field F , which is endowed with a symmetric bilinear form Φ : E → F and has the property that every infinite dimensional subspace U ⊆ E satisfies dimU < dimE. Gross spaces over uncountable fields exist (in certain dimensions) (see [G/O]). The existence of a Gross space over countable or finite fields (in a fixed dimension not abo...

Working papers from the Stockholm Institute of Transition Economics and East European Economies are preliminary in nature, and are circulated to promote discussion and critical comment. Any references to individual working papers should clearly state that the paper is preliminary. The views expressed here are the authors' own and not necessarily those of the Institute or any other organization ...

Examples 1.1. • Y ∼= P, D a nodal cubic. • Y a complete nonsingular toric surface, D the toric boundary (i.e, the complement of the big torus orbit Gm). • Blowups: Given a Looijenga pair (Y ,D), we can take “toric blowups,” where Y is the blowup of Y at a nodal point of D and D is the inverse image of D). Note that toric blowups do not change U . “non-toric blowups,” where Ỹ is the blowup of Y ...

ly isomorphic as rings are conjugate in B. 146 BRIAN CONRAD (APPENDIX BY W. R. MANN) Remark A.10. The order ( A mn A A ) in (2) is the intersection of the maximal orders M2(A) and γnM2(A)γ−1 n = ( A mn m−n A ) , where γn = ( 0 πn 1 0 ) . This example is called a standard Eichler order. Proof. For the first part, it suffices to show that the set R of elements of B integral over R is an order. Th...
