The advent of deep-sea exploration using video cameras has uncovered extensive sponge aggregations in virtually all oceans.Yet, a distinct type is herein reported from the Mediterranean: a monospecific reef-like formation built by the lithistid demosponge Leiodermatium pfeifferae.Erect, plate-like individuals (up to 80 cm) form bulky clumps, making
This study examines the effects of psychological contract baseball scoreboards for sale breach (PCB) on employee mental and physical health (SF-12) using a sample of 3,870 employees derived from a German longitudinal linked employer-employee study across various industries.Results of multivariate regression models and mediation analysis suggest tha
Using CHAMP magnetic field data we study the behaviour of the geomagnetic field during two mid latitude eclipses on 21 June 2001 and 22 September 2006.The possible influence of the eclipses on different ionospheric current systems, as seen in the magnetic field measured by CHAMP, is discussed.It is expected that the blocking of solar radiation duri
We evaluated and compared the performance of two popular neuroimaging processing platforms: Statistical Parametric Mapping (SPM) and FMRIB Software Library (FSL).We focused on comparing brain segmentations using Kirby21, a magnetic resonance imaging (MRI) replication study with 21 subjects and two scans per subject conducted only a few hours apart.
Copper is a trace element necessary for the normal growth and metabolism of living organisms.If exceeds its limit it becomes pollutant and causes pathological effects.Asian sea bass (Lates calcarifer) was exposed to sublethal concentrations of copper for 28 days and histopathological alterations were noticed in the gill, liver, muscle and intestine
