När ett nedslag gräver upp och modifierar Mars yta, genom att medföra material från djupare delar till ytan, öppnar det fönster ner till äldre geologi. Att försöka förstå ytegenskaper på Mars och hur källmaterialet beter sig vid ett nedslag kräver en metod från flera perspektiv. Tidigare forskning har främst fokuserat på ejecta och ejektamorfologi som en indikator på ytegenskaper. Däremot kan ävenWhen an impact excavates and modifies the Martian surface, by bringing deeper lying material to the surface, it opens a window into past geology. Trying to understand surface properties on Mars and how target material behaves during impact requires a multi-view approach. Previous research has focused mainly on ejecta emplacement and morphologies as a proxy for surface properties. However, interior

Summary: Existing approaches to modelling antibody concentration data are mostly based on finite mixture models that rely on the assumption that individuals can be divided into 2 distinct groups: seronegative and seropositive. Here, we challenge this dichotomous modelling assumption and propose a latent variable modelling framework in which the immune status of each individual is represented along

Protein C (PC), a 62 kDa multi-modular zymogen, is activated to an anticoagulant serine protease (activated PC or APC) by thrombin bound to thrombomodulin on the surface of endothelial cells. PC/APC interacts with many proteins and the characterisation of these interactions is not trivial. However, molecular modelling methods help to study these complex biological processes and provide basis for r

Effects of ultraviolet (UV)-B radiation and acidification on pelagic carbon flux in a humic lake (dissolved organic carbon [DOC] similar to15 mg C L-1) were studied in a mesocosm experiment during the summer of 2000. Triplicate tanks (107 liters volume, 1 m high) were exposed to natural solar radiation, a daily extra dose of UV-B radiation, or kept dark. One set of tanks was submitted to a decreas

Ultrafast accelerator-based sources combined with synchronized femtosecond lasers are currently being developed. The method described here is intended as a jitter monitor at such facilities. We report on the possibility of extracting a time-offset signal between two different synchronized ultrashort light pulses. The method is based on sum-frequency generation in a nonlinear crystal. Aiming at ext

The findings from the Prostate Cancer Prevention Trial (PCPT) and how they relate to the management of prostate disease were reviewed by leading European urologists during a meeting held in December 2005. The consensus opinions that were reached were endorsed by the European Association of Urology and are documented here. The key points of the consensus are as follows: (1) The overall results from

Quality of life has various dimensions with multiple meanings for people. One vital issue is whether a person's subjective experienced quality of life correlates with his or her personality. Several studies show a correlation between personality and quality of life, life satisfaction or well-being. The aim of this study was to examine the relationship between personality and life quality, in parti

We describe the history, construction, and use of a portable walk-in wader trap (i.e., modified Ottenby trap) designed to be used in field expedition conditions. It is rectangular-shaped, 120 x 41 x 32 cm when operational, weighs between 1.5 and 2 kg (depending on materials used) and can be folded flat for easy transportation. It consists of several metal frames filled with fishing net, and has a

A new method for absorbed-dose assessment in radionuclide therapy is presented in this paper. The method is based on activity quantification by the conjugate-view methodology, applied to serial whole-body, anterior-posterior, scintillation-camera scans. The quantification method is an extension of previous studies, and includes separate corrections for attenuation, scatter, and overlapping organs.

Random mesh phases share many common features with the classical lamellar phase in that they are layered phases; but crucially, they possess nonuniform interfacial curvature, since the lamellae are pierced by water-filled pores. The introduction of curvature into the lamellae has been posited as a transitional precursor for other lyotropic phases. In this paper, we show that simple H-2 nuclear mag

Lipid droplets are cytoplasmic organelles which serve as storage sites for neutral lipids. Adipose differentiation-related protein (ADRP) is intrinsically associated with the surface of lipid droplets and is believed to play a major role in the maintenance of lipid stores in non-adipocytes. ADRP abundance is intimately linked to the amount of lipid found within cells and agents which increase the

We discuss the main properties of the Galactic globular cluster (GC)blue straggler stars (BSSs), as inferred from our new catalog containingnearly 3000 BSSs. The catalog has been extracted from thephotometrically homogeneous V versus (B-V) color-magnitude diagrams(CMDs) of 56 GCs, based on Wide Field Planetary Camera 2 images of theircentral cores. In our analysis, we used consistent relative dist

Each of 102 Nordic routine clinical biochemistry laboratories collected blood samples from at least 25 healthy reference individuals evenly distributed for gender and age, and analysed 25 of the most commonly requested serum/plasma components from each reference individual. A reference material ( control) consisting of a fresh frozen liquid pool of serum with values traceable to reference methods

Hypothesis: En bloc esophagectomy (EBE) provides improved survival over transhiatal esophagectomy (THE) in patients with similarly sized transmural tumors (T3) and lymph node metastases (N1). Design: A retrospective case-control study of 2 methods of esophageal resection for cancer. Setting: University hospital (tertiary referral center for esophageal disease). Patients: There were 49 patients (27

In order to reduce the total enzyme consumption in high-solids static hydrolysis of nonwashed steam-exploded willow Salix caprea by mixed cellulase of Trichoderma reesei + Aspergillus foetidus, two different approaches were proposed. In the first case, the enzyme activity adsorbed on residual solids after extended hydrolysis was used for hydrolysis of the newly added substrate. The initial mixing
