Organisms usually benefit from heterogeneous conditions, but, by doing so, may reduce the degree of heterogeneity. The question therefore arises how heterogeneity is maintained. We investigated within-year spatiotemporal patterns in a monospecific stand of a submerged plant (fennel pondweed, Potamogeton pectinatus), with the novelty that we distinguished between different forms of heterogeneity: s

Maria Sjöberg behandlar i Kritiska tankar om historia hur ett antal skeden i världshistorien har framställts och framställs i historiska verk.

Measurement of cortisol concentration can contribute important information about an individual's ability to adjust to various environmental demands of both physical and psychosocial origin. However, one uncertainty that affects the possibilities of correctly interpreting and designing field studies is the lack of observations of the impact of seasonal changes on cortisol excretion. For this reason

I denna studie visar vi olika fördelar med vår e-learning-modell, som har „räddat” småspråket rumänska. Vi konstaterar dessutom att denna utbildningsmodell kan tillämpas på vilket annat språk som helst, för att uppnå ett flexibelt, rationellt, kostnadseffektivt och modernt lärande.

A candidate for chiral bands was found in Tl-198 for the first time in a mass region of oblate (or nonaxial with gamma >= 30 degrees) deformed nuclei. Two bands show very similar quasiparticle alignments, moments of inertia, and B(M1)/B(E2) ratios. They have a relative excitation energy of about 500 keV and different patterns of energy staggering. Calculations using the two-quasiparticle-plus-tria

This paper is the follow up of a previous work and its target is to demonstrate that the best fuel for a Compression Ignition engine has to be with high Octane Number. An advanced injection strategy was designed in order to run Gasoline in a CI engine. At high load it consisted in injecting 54 % of the fuel very early in the pilot and the remaining around TDC; the second injection is used as ignit

Although estrogen receptor-alpha (ERalpha) is a marker used to identify breast cancer patients most likely to benefit from endocrine therapy, approximately 50% of ERalpha-positive breast carcinomas are resistant to tamoxifen. Preclinical studies have shown that phosphorylation of ERalpha at serine-118 (ERalphaS118-P) is required for tamoxifen-mediated inhibition of ERalpha-induced gene expression.

In this work, the photofragmentation subsequent to valence and Cd4d photoionization of cadmium dichloride (CdCl2) were studied using He I and synchrotron excitation. The measurements were performed with a photoelectron-photoion coincidence (PEPICO) setup, and the connection between the singly ionized electronic states and cationic fragments was investigated. The valence-ionized states were found t

A method for reaching longitudinal dispersion coefficient accounting sinuosity effects is suggested. The proposed method was verified using 43 sets of measured field data from previous study were collected from 30 streams and these data were chosen depends on characteristics availability (flow parameters, fluid properties and Sinuosity). Statistical programs namely MINITAB and SPSS were used to de

Photon time-of-flight spectroscopy (PTOFS) is a powerful tool for analysis of turbid materials. We have constructed a time-of-flight spectrometer based on a supercontinuum fiber laser, acousto-optical tunable filtering, and an InP/InGaAsP microchannel plate photomultiplier tube. The system is capable of performing PTOFS up to 1400 nm, and thus covers an important region for vibrational spectroscop

Plant functional response groups (PFGs) are now widely established as a tool to investigate plant-environment relationships. Different statistical methods to form PFGs are used in the literature. One way is to derive emergent groups by classifying species based on correlation of biological attributes and subjecting these groups to tests of response to environmental variables. Another way is to sea

Background: There are limited prognostic data for locally advanced prostate cancer PCa to guide in the choice of treatment. Objective: To assess mortality in different prognostic categories among men with locally advanced PCa managed with noncurative intent. Design, setting, and participants: We conducted a register-based nationwide cohort study within the Prostate Cancer DataBase Sweden. The enti

An updated detailed kinetic mechanism for ozone combustion is developed. The contemporary choice of the reaction rate constants is presented with emphasis on their uncertainties. Model predictions are compared with available experimental data for ozone decomposition flames and with the Moscow State University (MSU) mechanism used elsewhere in the literature. These two models show similar performan

Introduction: Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes increasingly difficult during rotational movements. We aimed to evaluate five different methods (metrics) of processing acceleration signals on their ability to

Tourist research on life in "The Experience Economy" has led to a focus oil the eventful cold dramatic, on ways of packaging and marketing "great experiences" that turn a heritage into all event, a city into desires, a museum into all adventure. There is a lot of talk about the production of great atmospheres and exciting events, but tourist life is of course full of non-events, indifferent or bad

Paraphrasing Slavoj Zizek (1991: 65), the paper proposes that: 'The Scania Truck does not exist': it is nothing but 'the symptom of passionate users', its power of fascination masks the void of its nonexistence'. Along the same line of reasoning, it argues, again paraphrasing Zizek, that 'the customized Scania truck is becoming the sinthome of its user'. (c.f. Zizek, 1991: 137). The paper does so
