Light-dependent growth of phytoplankton is a fundamental process in marine ecosystems, but we lack a comprehensive view of how light utilization traits vary across genotypes and species, and how this variation is structured by cell size, taxonomy, and environmental gradients. Here, we compile 308 growth-irradiance experiments performed on 119 species of marine phytoplankton from all major funct...

In cat papillary muscles at 30 degrees C, bathed with Tyrode's solution containing 2.25 mM Ca2+, the effect of various inotropic interventions (varying the stimulus frequency and continual paired stimulation) on the shape of the steady state length-tension relation was examined at lengths from Lmax, where tension production is maximal, to 0.87 Lmax. The relative steepness of the length-tension ...

The photo-excitation and relaxation of a new cyclometalated complex, Ir(ppy)2fppy, is investigated through the measurement of absorption and photoluminescence spectra. Comparison of Ir(ppy)2fppy with Ir(ppy)3 reveals that the lowest energy excited state of Ir(ppy)2fppy is localised on the aldehyde-substituted ligand, thus giving the complex its characteristic orange emission (lmax # 600 nm). OL...

In 14 normal subjects and in 13 patients with obstructive pulmonary diseases, we studied the variability within an individual of values for the maximal expiratory flow rate (‘Vmnx) recorded simultaneously vs expired pulmonary volume (at the mouth) and vs thoracic volume (measured with a body plethysmograph). We found that the variance of lmax within an individual at 25, 50, and 75 percent of th...

Combining a sterically bulky, electron-deficient 2-(2,4-difluorophenyl)-4-(2,4,6-trimethylphenyl)pyridine (dFMesppy) cyclometalating C4N ligand with an electron rich, highly rigidified 1,10-(a,a0-o-xylylene)-2,20biimidazole (o-xylbiim) N4N ligand gives an iridium complex, [Ir(dFMesppy)2(o-xylbiim)](PF6), that achieves extraordinarily bright blue emission (FPL = 90%; lmax = 459 nm in MeCN) for a...

Magnesium is extracted with a chloroform solution of N-p-tolyl-2- thenohydroxamic acid (PTTHA) from aqueous solution of pH 9.5 .Mg-PTTHA complex is colourless and the colour is developed by adding quinalizarin into the extract. lmax and e of the complex are 590nm and 2.8´103 Lmol -1cm-1respectively.Most common  ions do not interfere in the determination of magnesi...

Introduction: The improvement of technology has increased noise levels in hospital Wards to higher than international standard levels (35-45 dB). Higher noise levels than the maximum level result in patient’s instability and dissatisfaction. Moreover, it will have serious negative effects on the staff’s health and the quality of their services. The purpose of this survey is to analyze the leve...

This article extends the scheduling problem with dedicated processors, unit-time tasks, and minimizing maximal lateness Lmax for integer due dates to problem, where along precedence constraints given on set V={v1,v2, …,vn} of multiprocessor a subset tasks must be processed simultaneously. Contrary classical shop-scheduling several processors fulfill task. Furthermore, two types may task V. We p...

The Fast Multipole Method (FMM) obeys periodic boundary conditions "natively" if it uses a Green function for computing the multipole expansion in interaction zone of each FMM oct-tree node. One can define "optimal" such method that results numerical solution converges to equivalent Particle-Mesh limit sufficiently high order multipoles. A discrete functional equation optimal be derived, but is...
