This article outlines an experimental and analytical expression study on the consequence of cement constituents, mix composition and curing conditions as regards self-desiccation in concrete. For this purpose nine concretes with three values of w/c (0.32, 0.38 and 0.50), based on two types of Portland Cement, were manufactured. Five per cent silica fume was used in one third of the concretes as ca

The existence of a DNA polymorphism at the hormone-sensitive lipase locus could be of great interest for genetic analysis of obesity and related disorders since hormone-sensitive lipase is the rate-limiting enzyme of adipose tissue lipolysis and therefore plays a key role in energy metabolism. The polymorphic dinucleotide repeat D19S120 was identified within a human genomic clone selected with a r

We present calculations of charm and beauty production at Tevatron within the framework of k(T)-factorization, using the unintegrated gluon distributions as obtained from the Linked Dipole Chain model. The analysis covers transverse momentum and rapidity distributions and the azimuthal correlations between b and (b) over bar quarks (or rather muons from their decay) which are powerful tests for th

Various new prognostic indicators have been identified for mammary carcinomas, but the issue of their significance remains unsettled. The prognostic impact of p53, c-erbB-2, and topoisomerase II alpha expression was investigated in relation to standard prognostic factors for carcinomas of the breast and to the tumour cell growth fraction. Paraffin-embedded specimens of 356 node-negative infiltrati

The rheological properties of starch extracted from ten different species of tropical tuber crops were examined using a Bohlin rheometer. Suspensions with starch concentrations of 3, 4 and 5% were gelatinised at 757C and fed into the rheometer cup. A C 25 measuring system was used and the heating rate was 1.57C/min, heating schedule 75-957C, holding at 957C for 600 s, cooling to 357C at 1.57C/min,

The Euro50 is a proposed 50m extremely large telescope for optical and infrared wavelengths. To study and predict the performance of the complete telescope system, an integrated model combining the structural model of the telescope, optics models, the control systems and the adaptive optics has been established. Wind and atmospheric disturbances are also included in the model. The integrated model

Scolecodonts are common microfossils in Palaeozoic rocks, bearing witness to the extensive radiation of jawed polychacte worms during the Ordovician Period. Information on Ordovician scolecodonts is increasing, though it is still patchy and strongly skewed towards Baltica and Laurentia. Comparison of the faunas of these two palaeocontinents indicates that approximately 50% of the genera, but only

Objective: To identify the major aggrecanase-and matrix metalloproteinase (MMP)-generated aggrecan fragments in human osteoarthritis (OA) synovial fluid and in human OA joint cartilage. Method Aggrecan fragments were prepared by CsCl gradient centrifugation. Fragment distributions were compared with aggrecanase-1 (ADAMTS-4) and MMP-3 digested human aggrecan by analysis with neoepitope antibodies a

A disturbed proprioception has been described in patients with an anterior cruciate ligament (ACL) deficient knee. The relation to demographic data and to different commonly associated anatomical lesions, as well as to subjective knee function, was prospectively studied in 16 consecutive patients after an acute knee ligament injury. All patients had a complete rupture of the ACL, but variable asso

Plasmodium relictum (lineage P-SGS1) is a widespread malaria parasite that causes disease of different severity in different species of birds. However, experimental studies on the effects of this parasite on avian hosts are uncommon. We investigated development of this lineage in experimentally infected greenfinches Carduelis chloris and compared the obtained data with the literature information a

To explore the effect of different degrees of oestrogenization on male voiding, by treating adult castrated and 5 alpha-dihydrotestosterone (DHT)-maintained male mice with different doses of oestrogens, as exposure of male mice to excessive amounts of oestrogens can cause bladder outlet obstruction (BOO); in addition, male mice lacking oestrogen receptor (ER)alpha (ERKO) or ER beta (BERKO) were st

In patients with rheumatoid arthritis, the presence of acute synovial inflammation is an indication of the activity of the disease. It is an important finding because it often influences therapeutic decisions. However, acute synovitis may be difficult to detect by clinical examination, especially if a joint effusion also is present. As gadolinium tetra-azacyclododecane tetraacetic acid (Gd-DOTA) c

Background: Single nucleotide polymorphisms (SNPs) represent the most frequent form of genetic variations. Some of the most sensitive methods for SNP genotyping employ synthetic oligonucleotides, such as the peptide nucleic acid (PNA). We introduce a new method combining allele-specific hybridization, PNA technology, and flow cytometric detection. We tested the design by genotyping a Danish basal

Primary structural information of anhydride binding to endogenous proteins is of interest in order to determine the mechanism causing the type-I allergy seen in many anhydride-exposed workers. In addition, studies on specific protein adducts may generate new methods for biological monitoring. In this study, the binding of hexahydrophthalic anhydride (HHPA) to human hemoglobin (Hb) in vitro was inv

Shikimic acid is one of several industrially interesting chiral starting materials formed in the aromatic amino acid pathway of plants and microorganisms. In this study, the physiology of a shikimic acid producing strain of Escherichia coli (derived from W31 10) deleted in aroL (shikimic acid kinase II gene), was compared to that of a corresponding control strain W31 10) under carbonand phosphate-
