Resumen

To determine how sulfation alters the biological properties of dihydroxy bile acids, we compared the effects of 3-sulfodeoxycholate (SDC) and deoxycholate (DC) in the rat and rabbit intestine. While 5 mM DC induced water and electrolyte secretion and inhibited glucose absorption in the rat, SDC enhanced jejunal and ileal water and solute absorption. SDC had no effect in the rabbit ileum. In the rat jejunum DC caused mucosal injury and enhanced mucosal permeability while SDC had no effect. In vitro in the rabbit ileum, 10 mM SDC enhanced net sodium flux and decreased net residual flux, while 0.5 mM DC reduced net sodium flux and induced Cl- secretion. Both bile acids increased short-circuit current and potential difference and decreased tissue conductance. During reversed-phase, high-performance liquid chromatography SDC was more polar than DC. Sulfation reduced the ability of DC to destroy large unilamellar liposomes by a factor of 10. Thus, sulfation abolishes the effects of DC on the intestine by enhancing the polarity of this molecule. The enhancement of intestinal solute and water absorption by SDC requires further study.

Resumen

The existing compressive sensing (CS) reconstruction algorithms require enormous computation and reconstruction quality that is not satisfying. In this paper, we propose a novel Dual-Channel Reconstruction Network (DC-Net) module to build two CS reconstruction networks: the first one recovers an image from its traditional random under-sampling measurements (RDC-Net); the second one recovers an image from its CS measurements acquired by a fully connected measurement matrix (FDC-Net). Especially, the fully connected under-sampling method makes CS measurements represent original images more effectively. For the two proposed networks, we use a fully connected layer to recover a preliminary reconstructed image, which is a linear mapping from CS measurements to the preliminary reconstructed image. The DC-Net module is used to further improve the preliminary reconstructed image quality. In the DC-Net module, a residual block channel can improve reconstruction quality and dense block channel can expedite calculation, whose fusion can improve the reconstruction performance and reduce runtime simultaneously. Extensive experiments manifest that the two proposed networks outperform state-of-the-art CS reconstruction methods in PSNR and have excellent visual reconstruction effects.

Resumen

To determine the quantitative roles of the basolateral and luminal Na+-dicarboxylate (Na-DC) cotransporters in establishing and maintaining the α-ketoglutarate (αKG) gradient required for renal tubular secretion of organic anions, we measured net steady-state transepithelial secretion of fluorescein (FL) in real time in isolated, perfused S2 segments of rabbit renal proximal tubules. Net “basal” FL secretion in the absence of exogenous αKG had a K t of ∼4 μM and a maximal transepithelial secretion rate ( J max) of ∼380 fmol ⋅ min−1 ⋅ mm−1(where K t is the FL concentration that produces one-half the J max). It could be almost completely inhibited by basolateral p-aminohippurate (PAH). Selective inhibition of the basolateral Na-DC cotransporter indicated that recycling via this transporter of αKG that had been exchanged for FL supports ∼25% of the “basal” FL secretion. Physiological αKG concentrations of 10 μM in the bath or 50 μM in the perfusate stimulated net secretion of FL by ∼30 or ∼20%, respectively. These data indicate that the basolateral Na-DC cotransporter supports ∼42% of the net FL secretion. The luminal and basolateral effects of physiological concentrations of αKG were additive, indicating that the combined function of the luminal and basolateral Na-DC cotransporters can support ∼50% of the net FL secretion. This apparently occurs by their establishing and maintaining ∼50% of the outwardly directed αKG gradient that is responsible for driving basolateral FL/αKG exchange. The remaining ∼50% would be maintained by metabolic production of αKG in the cells.

Resumen

e16698 Background: The coexistence of neuroendocrine tumors and pancreatic adenocarcinoma is rare, and treatment of such mixed tumors is challenging due to the differences in their natural course and response to systemic therapy. There is growing evidence that vitamins affect the biology of pancreatic tumors. The purpose of the study was to measure concentrations of retinol (RET), α-tocopherol (α-TCP) and diene conjugates (DC) in the blood of patients with pancreatic cancer in order to reveal its pathogenetic characteristics. Methods: Blood levels of RET and α-TCP (ELISA methods, Cloud-Clone Corp, USA), their ratio and DC concentrations (biochemical method) were measured before treatment if 42 patients with pancreatic cancer: adenocarcinoma (AC), T1-3N0-1M0, n = 9; AC with a neuroendocrine component (AC+NE) (up to 30%), n = 21; neuroendocrine tumors (NET), T1-3N0-1M0, n = 12. 22 healthy men of similar age were controls. All patients gave their voluntary informed consent for the study. Results: RET levels in all patient were statistically significantly lower than in controls: in AC by 3.8 times, in AC+NE by 1.9 times, in NET by 3.7 times (p = 0.0000). Concentrations of α-TCP in AC were 1.6 times (p = 0.0011) lower than in controls, in AC+NE were similar, and in NET α-TCP was 1.5 times higher than in controls (p = 0.0000). The ratio of α-TCP/RET in all patients significantly exceeded control values: in AC by 2.2 times, in AC+NE by 1.6 times, in NET by 5.7 times (p = 0.0000). Levels of DC in all patients were higher than in controls: in AC by 2.5, in AC+NE by 2.1, in NET by 2.7 times (p = 0.0001). Conclusions: Changes in serum levels of RET and α-TCP differ in patients with AC, NET and mixed tumors, which causes changes in the balance of vitamins and can contribute to a prooxidant effect, as evidenced by an increase in DC levels.

Resumen

The world we live in, is becoming more and more dependent on electrical energy, which, sadly, still heavily relies on outdated techniques involving the burning of fossil fuels. Fortunately, more and more people are accepting the fact that this system simply isn’t sustainable in the longer-run. Even if air pollution wasn’t a huge factor, the shortage of these resources is something that is bound to happen in the nearest future, and it would pose an impassable obstacle towards the future growth of mankind. Hence, importance of renewable energy is such an important trend for the future of mankind. At present, net AC meters are available for measurement of four quadrant energy, which is used at output of both on grid and off grid solar inverter. This meter can measure both, energy fed into the grid and energy utilize from the grid. However Energy generated by solar panel cannot be measured directly. Even in off grid inverter the present net meter cannot measure energy generated by solar panel. In case of DC micro grid, where DC energy is used/ consumed directly by the load, the present net meter cannot be used as they can be used in AC energy measurement only. With the launch and implementation of national energy saving and emission reduction policies in relation to distributed power supply by renewable power generation, the DC energy metering technology will become an inevitable trend, breaking the landscape dominated by AC in the field of electric energy metering. This paper describes introduction, block diagram [1], Hardware and software description for development of dc energy meter.

Resumen

In natural and man-made environments microorganisms encounter a number of positive (growth) and negative (toxic and predatory) influences which affect their survival. Understanding microbial survival and potential for regrowth is important for risk assessment in a variety of water types and settings. However, the behaviour of microorganisms in fluvial systems cannot be completely simulated in the laboratory. We have previously studied the survival of several microorganisms in river water in the laboratory and in situ. Frequently our results were variable when sampling sites were separated temporally and spatially. In order to further understand why such differences may occur, we examined the effect of transient nutrient plugs on microbial survival and regrowth in parallel in two model systems with different characteristics: a flow-through hollow fibre diffusion (HFD) system and static diffusion chambers (DC). We focused on the behaviour of Escherichia coli because of its widespread use as an indicator. Results showed a different response of E. coli to transient presence of nutrients in the two systems; both systems responded to nutrient spikes but the HFD system responded more rapidly. For 1h and 2h nutrient spikes, the peak populations in the HFD system were seen 5h (62% net increase) and 8h (650% net increase) after nutrient addition, respectively. In the DC the corresponding figures were 7h (18.5% net increase) and 12h (300% net increase) hours. However, decline in microbial numbers was more rapid in the HFD than the DC system. When this was tested further with repeated short nutrient plugs (10min), the net growth in the CD system was higher than in the HFD. The main question that arises from these studies is under what conditions, if any, does the rapid response HFD model become more relevant for field conditions?

Resumen

Making electricity grids smarter and facilitating them with integration of renewable energy sources (RES) and energy storage are fairly accepted as the necessary steps to achieve a sustainable and secure power industry. To enable Net-zero energy and optimize power management for future homes or buildings, DC electric distribution systems (DC Nano-grid) find feasibility and simplicity for integrating renewable energy sources and energy storage. However, integrating the sources and loads in a simple, robust and smart way is still challenging. High voltage lithium-ion battery should be seriously considered concerning the overcharge/over-discharge risk. Dissipative cell equalization and its performance are studied. Non-dissipative equalization methods are reviewed using an energy flow chart. Typical charging schemes and the related over-charge risk are illustrated. A Lithium-ion battery charging profile based on VCell_Max/Min monitoring is proposed and validated with experimental results in an 8.4kW bidirectional battery charger for DC future home. For the DC future home emulator testbed, a grid interface converter, i.e. energy control center (ECC) converter, is reviewed with functions identification. A PV system with different configurations is compared to further expand the common MPPT region, and a DC-DC converter is designed as the interface between PV panels and DC bus, facilitating maximum power point tracking (MPPT) as well as fulfill the system energy management requirement. An 8.4kW multi-phase bidirectional battery charger with Si IGBT in DCM operation is designed to achieve high efficiency and to be the interface converter between lithium-ion battery and DC bus, enhancing the battery system management as well as increasing the system reliability. To integrate all the sources and loads in a simple, reliable and smart way, this thesis proposes a distributed droop control method and smart energy management strategy to enhance the Net-zero electric energy cost. All of the control strategies are applied to the DC future home with interactions among the energy control center (ECC), renewable energy sources, energy storage and load within a day/24 hours. System level energy management control strategies for Net-zero electric energy cost are examined and illustrated. A 10kW future home emulator testbed is built and introduced for concepts validation.

Resumen

Freedom of speech and the right to privacy are maybe the most important elements of a modern society, yet the rights are often violated. This fact was the main reason for writing this thesis covering P2P network models, anonymity, censorship resistance and their use in real P2P networks and publishing systems. We discuss their effectiveness and suitability for specific purposes, but also the security considerations of their use. The second part of this thesis presents the LSPP publishing protocol, which is an library implementation of an anonymous censorship resistant P2P network. Finally, we analyze the proposed protocol and compare it with existing solutions.

Resumen

This chapter describes the DC Commercial Internet. The ideal consists of economic liberty, market solutions to resource allocation problems, property rights over the Internet, and exploitation of positive externalities. The exemplar is the United States, especially its Supreme Court, which has judged networks as private spaces (‘walled gardens’) which can and should be monetized as their owners prefer. Such an approach, it is argued, will lead to greater innovation and value creation for the public, even at the cost of interoperability and net neutrality. Social networks have gained from this view, able to create closed networks within walled gardens benefiting from network effects to collect data about members. Facebook has offered free services in the developing world in order to bring more people online within its boundaries. An attempt to sell the .org domain to a private equity company, however, foundered. This model has been called ‘surveillance capitalism’.

Resumen

Abstract.—Despite increasing popularity of blue catfish Ictalurus furcatus with anglers, effective management of blue catfish has been hindered by limited information on appropriate sampling methods. We compared the efficiency, precision, and accuracy of low-frequency pulsed-DC electrofishing and experimental gill nets for use in estimating relative population abundance and size structure in 12 reservoirs. Electrofishing yielded greater catch rates and lower mean relative standard error (RSE) than gill nets. Similarly, the number of samples necessary to achieve a RSE = 0.25 was lower with electrofishing in most reservoirs. Gill-net catch per unit effort (CPUE) and electrofishing CPUE were strongly correlated (P < 0.01), and length-frequency distributions were also similar between gear types in many reservoirs examined. Where they differed, there was no consistent pattern, suggesting that differences were due to low precision (caused by low numbers of fish captured) rather than gear bias. Our analysis indicated that both low-frequency pulsed-DC electrofishing and gill netting effectively measured relative abundance of blue catfish. In most cases, electrofishing was more efficient at estimating CPUE and size structure (requiring fewer samples to achieve comparable precision); thus, we recommend using this gear when estimating these parameters for reservoir blue catfish populations.

Resumen

In the previous chapter, we dealt with the distribution of solutes between gas, liquid and solid phases in the soil at equilibrium; and with the rates of redistribution between these phases within soil pores. In this chapter, we consider movement of the order of 1 –1000 mm from one volume of soil to another. Such movements occur largely by diffusion and mass flow of the soil solution or soil air, and by mass movement of the body of the soil. Major movements that involve the balance and amount of solutes in the whole soil profile, including plant uptake and drainage losses, are treated in chapter 11. The process of diffusion results from the random thermal motion of ions, atoms or molecules. Consider a long column of unit cross-section orientated along the x axis, and containing a mixture of components in a single phase at constant temperature and external pressure. If the concentration of an uncharged component is greater at section A than at section B, then on average more of its molecules will move from A to B than from B to A. The net amount crossing a unit section in unit time, which is the flux, is given by the empirical relation known as Pick’s first law: . . . F = − D dC/dx (4.1) . . . where F is the flux, and dC/dx is the concentration gradient across the section. The minus sign arises because movement is from high to low concentration in the direction of increasing x. The diffusion coefficient, D, is thus defined by the equation as a coefficient between two quantities, F and dC/dx, which can be measured experimentally. It is not necessarily a constant. The diffusion coefficient of the molecules in a phase is directly proportional to their absolute mobility, u, which is the limiting velocity they attain under unit force. Terms D and u are related by the Nernst-Einstein equation: . . . D = ukT (4.2) . . . where k is the Boltzmann constant and T is the temperature on the Kelvin scale. The Nernst-Einstein equation is derived as follows (Atkins 1986, p. 675).

Resumen

Abstract.—Flathead catfish Pylodictis olivaris are native to Missouri and comprise one of the most important recreational and commercial fisheries in Missouri. Our specific study objective was to describe catch statistics for flathead catfish populations in moderate-large rivers in Missouri to provide sampling guidance for fisheries managers where a paucity of information existed. We used low-frequency (15 Hz) DC electrofishing and hoop nets in segments of the Grand, Lamine, and Platte rivers and pools 20–22 of the upper Mississippi River (UMR) during April–July 2006–2007. Electrofishing mean catch per unit effort (CPUE) ranged from 13.1 (Lamine) to 116.6 (UMR) fish/h while hoop-net mean CPUE ranged from 0.131 (Lamine) to 0.694 (Grand) fish/hoop-net-night. Length distributions showed that hoop nets caught a higher relative abundance of flathead catfish over 40 cm total length (TL) compared to electrofishing, most notably in the Grand and Platte rivers, whereas electrofishing caught relatively more flathead catfish under 35 cm TL in all rivers compared to hoop nets. Our results indicate that a combination of low-frequency (15 Hz) electrofishing and hoop nets should be used during the period of April 15 through July 15 to best represent length structure and relative abundance of flathead catfish populations in these rivers. More specifically, we found low-frequency electrofishing to be most effective for stock size and larger flathead catfish during mid-April to mid-June; however, these results were not as conclusive in 2007. As popularity and angling pressure of these fisheries increases, our results will provide managers with sampling guidance and baseline information in efforts to develop high-quality flathead catfish populations in selected rivers.

Resumen

This paper investigates the micropumping action using orthogonal electrode pattern. It is reported in literature that the high microflows velocity can be achieved using orthogonal electrode pattern when excited by AC signals. Here in this paper we will investigate the effect of both AC and DC signal on orthogonal electrode pattern. We will also investigate the flow in an orthogonal electroosmotic micropump, where the combination of both DC and AC voltages were applied to optimize the fluid flow rate. The design of an orthogonal electrode pair, improves the non-uniformity in electric field, as a result producing stronger net flows at lower voltages. The capacitive electrode polarization and faradaic polarization are proposed to explain the different flow patterns. The fluid flow is explained by impedance analysis and velocity measurement. This investigation of microflow can improve the understanding of electrokinetics and hence effectively manipulate fluids.
