The cosmological QCD transition affects primordial density perturbations. If the QCD transition is first order, the sound speed vanishes during the transition and density perturbations fall freely. For scales below the Hubble radius at the transition the primordial Harrison-Zel’dovich spectrum of density fluctuations develops large peaks and dips. These peaks grow with wave number for both the ...

Hemispherical photography (HP) is extensively used for both canopy architecture such as leaf area index (LAI), and solar radiation regime determinations under forest canopies. This is done mainly by assuming that foliage elements occur in a spatially random manner. However, the majority of world forests occur in heterogeneous ecosystems and topography with rather complex canopy architecture. To...

Clumping in hot star winds can significantly affect estimates of mass-loss rates, the inferred evolution of the star and the environmental impact of the wind. A hydrodynamical simulation of a colliding winds binary (CWB) with clumpy winds reveals that the clumps are rapidly destroyed after passing through the confining shocks of the wind-wind collision region (WCR) for reasonable parameters of ...

The effects of habitat fragmentation and their implications for biodiversity is a central issue in conservation biology which still lacks an overall comprehension. There is not yet a clear consensus on how to quantify fragmentation even though it is quite common to couple the effects of habitat loss with habitat fragmentation on biodiversity. Here we address the spatial patterns of species dist...

Hot massive stars exhibit strong stellar winds that enrich the surrounding interstellar medium and affect stars' evolution. However, are inhomogeneous (clumped) difficult to model in radiative transfer codes. To produce more realistic spectra many codes use a volume-filling factor approach incorporate effects of clumping. While this is convenient it simplistic. We introduce an alternative clump...

Possible observables of baryon number clustering due to the instabilities occurring at a first order QCD phase transition are discussed. The dynamical formation clusters can be described by numerical fluid dynamics, augmented with gradient term and an equation state mechanically unstable region. It is shown that description this transition, in nuclear collisions, will lead dense boundary. State...

Introduction: Automated hematology analyzer platelet counts can be performed using either the impedance (PLT-I) method or fluorescent nucleic acid staining (PLT-O) method. Estimated (PLT-E) calculated a digital morphology by evaluating peripheral blood smear. Our objective was to compare values detected on Mindray BC-6200 device PLT-E count MC-80 analyzer. Material and methods: Complete cell fi...
