The carbon dioxide flux through the air-water interface of coastal freshwater ecosystems must be quantified to understand the regional balances of carbon and its transport through coastal and estuarine regions. The variations in air-sea CO2 fluxes in nearshore ecosystems can be caused by the variable influence of rivers. In the present study, the amount of carbon emitted from a tropical coastal river was estimated using climatological and biogeochemical measurements (2002-2010) obtained from the basin of the Capibaribe River, which is located in the most populous and industrialized area of the northeast region of Brazil. The results showed a mean CO2 flux of +225 mmol·m-2·d-1, mainly from organic material from the untreated domestic and industrial wastewaters that are released into the river. This organic material increased the dissolved CO2 concentration in the river waters, leading to a partial pressure of CO2 inthe aquatic environment that reached 31,000 μatm. The months of April, February and december (the dry period) showed the largest monthly means for the variables associated with the carbonate system (, dIC, CO2(aq), CO32-, TA, temperature and ph). This status reflects the state of permanent pollution in the basin of the Capibaribe River, due, in particular, to the discharge of untreated domestic wastewater, which results in the continuous mineralization of organic material. This mineralization significantly increases the dissolved CO2 content in the estuarine and coastal waters, which is later released to the atmosphere.

The wave-particle duality of light is a controversial topic in modern physics. In this context, this work highlights the ability of the wave-nature of light on its own to account for the conservation of energy in light-matter interaction. Two simple fundamental properties of light as wave are involved: its period and its power P. The power P depends only on the amplitude of the wave’s electric and magnetic fields (Poynting’s vector), and can easily be measured with a power sensor for visible and infrared lasers. The advantage of such a wave-based approach is that it unveils unexpected effects of light’s power P capable of explaining numerous results published in current scientific literature, of correlating phenomena otherwise considered as disjointed, and of making predictions on ways to employ the electromagnetic (em) waves which so far are unexplored. In this framework, this work focuses on determining the magnitude of the time interval that, coupled with light’s power P, establishes the energy conserved in the exchange of energy between light and matter. To reach this goal, capacitors were excited with visible and IR lasers at variable average power P. As the result of combining experimental measurements and simulations based on the law of conservation of energy, it was found that the product of the period of the light by its power P fixes the magnitude of the energy conserved in light’s interaction with the capacitors. This finding highlights that the energy exchanged is defined in the time interval equal to the period of the light’s wave. The validity of the finding is shown to hold in light’s interaction with matter in general, e.g. in the photoelectric effect with x-rays, in the transfer of electrons between energy levels in semiconducting interfaces of field effect transistors, in the activation of photosynthetic reactions, and in the generation of action potentials in retinal ganglion cells to enable vision in vertebrates. Finally, the validity of the find

despite the fact that a radio frequency (RF) sh.elding box affects a coil inductance used in matching network,RF engineers have used a coil inductance measured in open space on designing matching networks since it is difficult to precisely measure the coil inductance within the RF sh.elding *** this work,we investigate the influences of the RF sh.elding box on the coil inductance via a 3d full electromagnetic wave *** results shows that the coil inductance decreases from-6.0% to-11.9% compared with its ideal inductance depending on coil positions within the RF sh.elding *** inductive and capacitive coupling between the coil and surfaces of the RF sh.elding box contribute to the reduction of the coil *** expect that these results would be useful for those who design RF matching networks.

Bacteriophage Morphological Characterization by Using Transmission electron Microscopy

Bacteriophages or more commonly ＂phages＂ are bacterial viruses. They are ubiquitous and good indicators of bacterial contaminations since their prevalence is high in those environments where their hosts are abundant. Phage classification is based on morphology and for this reason, even though it is considered an old technique, Tem （Transmission electron Microscopy） still plays a key role in their characterization. In the present work, the authors focused on Tem analysis of phage ФApr-1 isolated against Lactococcuslactis （L. lactis）, implicated in industrial fermentations and of phage ФIZSAM-1, active against Listeria monocytogenes （L. monocytogenes）, isolated from the environment. For observation with Tem （em 900T-Zeiss）, phages were harvested in liquid media and were negative stained with fosfotungstic acid 2‰. An accurate viral ultrastructure analysis by using Tem is fundamental not only in the first approach of characterization of newly isolated phages but also for providing useful information to go further to the selection process as potential bio-decontaminants.

This work discusses the combination of two thermodynamic cycles seeking to improve the overall chemical energy conversion rate into mechanical energy. here one engine operates according a Rankine cycle in order to use part of the thermal energy released to the boundary, i.e., the neighboring atmosphere. The analysis of this combined cycle shows that it might, under proper condition, represent a gain of 1.2% in the overall delivered engine power.

Guided Folding of Life’s Proteins in Integrate Cells with holographic Memory and GM-Biophysical Steering

Open Journal of Biophysics 2018年第3期8卷 117-154页

作者： dirk K. F. Meijer hans J. h. Geesink University of Groningen Groningen The Netherlands Biophysics Group Loon op Zand The Netherlands

The current geometric and thermodynamic approaches in protein folding studies do not provide a definite solution to understanding mechanisms of folding of biological proteins. A major problem is that the protein is first synthesized as a linear molecule that subsequently must reach its native configuration in an extremely short time. hydrophobicity-hydrophilicity models and random search mechanism cannot explain folding to the 3-d functional form in less than 1 second, as it occurs in the intact cell. We propose an integral approach, based on the embedding of proteins in the whole cellular context under the postulate: a life protein is never alone. In this concept the protein molecule is influenced by various long and short distance force fields of nature such as coherent electromagnetic waves and zero-point energy. In particular, the role of solitons is reviewed in relation to a novel GM-scale biophysical principle, revealed by us. This recent finding of a set of discrete em frequency bands, that either promote or endanger life conditions, could be a key in further studies directed at the morphogenetic aspects of protein folding in a biological evolutionary context. In addition, an alternative hypothesis is presented in which each individual cell may store integral 3-d information holographically at the virtual border of a 4-d hypersphere that surrounds each living cell, providing a field receptive memory structure that is instrumental in guiding the folding process towards coherently oscillating protein networks that are crucial for cell survival.

electromagnetic Waves from TNT Explosions

引用

Journal of electromagnetic Analysis and Applications 2014年第10期6卷 280-295页

作者： A. L. Kuhl d. A. White B. A. Kirkendall Lawrence Livermore National Laboratory Livermore California USA

Experimental observations indicate that electromagnetic (em) radiation is emitted after the detonation of high explosives (hE) charges. The movement of ionized atoms, particles and electrons seems to be the underlying cause. Expansion of the detonation products (dP) drives a strong (~1 kb) shock in surrounding air. This forms an intense thermal wave (T ~11,000 K) with duration of ~20 microseconds. Such temperatures create significant ionization of the air. According to Ohm’s Law, movement of ionized patches generates current;and according to the Biot-Savart Law, such currents induce electric and magnetic fields. We investigate these effects through numerical simulations of TNT explosions. A high-order Godunov scheme is used to integrate the one-dimensional conservation laws of gasdynamics. An extremely fine grid (10 microns) was needed to get converged temperature and conductivity profiles. The gasdynamic solution provided a source current, which was fed into a time-domain Green’s function code to predict three-dimensional electromagnetic waves emanating from the TNT explosion. This analysis clearly demonstrates one mechanism—the Boronin current—as the source of em emissions from TNT explosions, but other mechanisms are also possible.

应用端元分析模型对南黄海表层沉积物粒度数据进行了反演,分离出四个端元.根据各端元频率分布曲线及平面分布特征,结合南黄海沉积动力格局,分析了各端元与研究区物源和水动力环境的对应关系.端元1和端元2反映了海洋动力过程对陆源沉积物的输运和分选,端元3和端元4反映了海洋动力对残留砂的改造.南黄海海洋锋面主要对陆源较粗颗粒沉积物的输运有影响,陆源较粗颗粒沉积物基本不能跨越山东外海海洋锋面.陆源细颗粒沉积物受海洋锋面影响较小,并在潮汐动力条件较弱的南黄海中部大量沉降,构成南黄海中部泥质区主体.南黄海中部细颗粒沉积物可能有西北和西南两个不同物源方向,其北部沉积物主要来自沿岸流输运跨越锋面后的黄河沉积物的细颗粒部分,西南部沉积物主要来自跨越苏北海洋锋面具有长江和黄河混合物源的苏北沿岸沉积物的细颗粒部分.和直接利用沉积物粒度数据研究沉积动力环境的传统方法相比,利用沉积物粒度端元分析方法分离出的沉积物不同端元分析区域沉积动力环境效果更好.
