Abstract:

Het pasgeboren kalf is afhankelijk van de absorptie van colostrale immunoglobulinen of antistoffen. Een goed colostrummanagement is een van de belangrijkste preventieve maatregelen tegen infectieuze ziekten bij jonge kalveren. Toch worden hier nog veel fouten tegen gemaakt of bestaan er nog veel misvattingen. Bovendien is ook meer en meer bewijs voorhanden dat colostrum niet alleen van levensbelang is voor de aanvoer van antistoffen maar evenzeer voor de aanvoer van andere substanties, zoals groeifactoren en immuuncellen.

De nadruk wordt gelegd op een optimale hoefbalans, de absorptie van schokken, de gepaste mate van grip/afremmen versus glijden, optimale drukverdeling binnen de hoef, en het bevorderen van “breakover”. Ook met het hoefmechanisme moet rekening gehouden worden. Ideaal gezien worden de meeste van deze principes reeds gecombineerd in de pre

The Absorption Ratio method involves measuring the absorbance at two wavelengths, namely the iso-absorptive point and the maximum wavelength. Its method could be an option in determining the level of a drug. The aim of this study was to determine whether the absorption ratio method can be used to determine the levels of paracetamol (PCT), propyphenazone (PRO) and caffeine (CAF) in tablet form. The absorption ratio method was used to determine the levels of the mixed drug compound without the separation stage and using the maximum wavelength and iso-absorptif point.

Abstract:

The concept of absorptive capacity was introduced by Cohen and Levinthal in 1989 as an important condition for high innovativeness. Since then it has been enhanced through reconceptualisations and extended by various empirical studies. Despite the growing interest in the concept, the processes and practices of absorptive capacity have largely remained a "black box". To fill this gap, the paper develops a practice-based approach of absorptive capacity and provides an in-depth empirical investigation to shed more light on the practice of knowledge absorption.

This paper presents a dual-mechanism method to design a single-layer absorptive metasurface with wideband 20 dB RCS reduction by simultaneously combining the absorption and phase cancellation mechanisms. The metasurface comprises two kinds of absorbing unit cells with 10 dB absorption performance but different reflection phases. The impedance condition for 20 dB RCS reduction is theoretically analyzed considering both the absorption and the phase cancellation based on the two unit cells, and the relationship between the surface impedance and the reflection phase/amplitude is revealed.

Abstract:

Wider band and deeper radar cross section (RCS) reduction by lower profile is always a very noticeable subject in stealth material researches. Most of researchers have designed and measured the RCS reduction bandwidth with 10 dB standard, that is, the return energy is reduced by 90%. In this paper we present a dual-mechanism method to design a single-layer absorptive metasurface with wideband 20-dB RCS reduction by simultaneously combining the absorption mechanism and the phase cancellation mechanism. Firstly, the impedance condition for 20-dB RCS reduction is theoretically analyzed considerin

Abstract:

Poly(3,4-ethylenedioxythiophene) doped with the polymer anion poly(styrenesulfonate), PEDOT:PSS, is a common electrochromic material used in the preparation of electrochromic devices (ECDs). In this paper, the PEDOT:PSS doped with a solvent was used both as the electrode and the electrochromic functional layer for fabrication of ECDs on absorptive paper surfaces. The doped PEDOT:PSS dispersion was assessed for the film-forming evenness, sheet resistance and conductivity, and the performance of prepared ECDs for their color contrast and switching dynamics. The ECD performance is discussed in re

Abstract:

The acidic gas, Carbon dioxide (CO2) absorption in aqueous ammonia solvent was carried as an example for industrial gaseous treatment. The packed column was provided with a novel structured BX-DX packing material. The overall mass transfer coefficient was calculated from the absorption efficiency of the various runs. Due to the high solubility of CO2, mass transfer was shown to be mainly controlled by gas side transfer rates. The effects of different operating parameters on KGav including CO2 partial pressure, total gas flow rates, volume flow rate of aqueous ammonia solution, aqueous ammonia

Abstract:

Next generation aircraft rely heavily on lightweight honeycomb composite structures for improved electromagnetic wave scattering and stealth capabilities. This paper investigated the optimal design and analysis methods of multi-layer absorbent honeycomb composite structures. The effective electromagnetic parameters of anisotropic object were calculated accompany with the formulation of reflectivity for incident wave. A genetic algorithm is employed to optimize the RCS of the absorptive honeycomb composite in desired angle range. The thickness and the volume fraction of absorptive materials are

Abstract:

A strategy based on the decoupling design of two elementary structures, both made of coiled-up channels, is proposed. One channeling structure is designed for blocking sound transmission, while the other element is used for absorbing sounds at low-transmission frequencies. Based on this strategy, the sound-absorbing sample with air ventilation is fabricated and its high-absorption capability is demonstrated experimentally. The expanding of sound absorption bandwidth by combining different absorptive channels into the sample structure is also demonstrated. The proposed method provides a new rou

Abstract:

The sound field in reverberation chambers used for measuring sound absorption coefficients is usually non-diffuse, leading to inaccuracies and disagreements in the results. In this paper, a diffusion equation model is applied to simulating reverberation chambers in order to obtain reverberant energy distributions and sound energy flows of the chamber under investigation in a more efficient way than wave-based simulation models. The computational efficiency of the diffusion equation lies in the fact that the meshing condition of the simulation domain is dictated by the room's mean-free path len

Abstract:

Glutamine is the primary metabolic fuel of the small intestine. To determine the effects of glutamine on intestinal electrolyte transport, piglet (3 days to 3 wk old) jejunum was bathed in Ussing chambers in a buffer containing 10 mM serosal glucose, and the effects of different concentrations of mucosal L-glutamine and D-glucose on short-circuit current and transmucosal Na+ and Cl- transport were measured. Resting jejunum secreted Na+ and Cl- in an electrogenic manner. In contrast to mucosal D-glucose (30 mM), which promoted electrogenic Na+ absorption (1.8 mueq.cm-2.h-1), mucosal L-glutamine

Abstract:

The guanylin family of peptides are effective regulators of intestinal physiology in marine teleosts. In the distal intestinal segments, they inhibit or reverse fluid absorption by inhibiting the absorptive short-circuit current ( Isc). The present findings demonstrate that mRNA from guanylin and uroguanylin, as well as at least one isoform of the guanylin peptide receptor, apical guanylyl cyclase-C (GC-C), was highly expressed in the intestine and rectum of the Gulf toadfish ( Opsanus beta). In the posterior intestine, GC-C, as well as the cystic fibrosis transmembrane conductance regulator a

Abstract:

Unlike iron, zinc absorption is influenced by dietary zinc intake, not zinc status. As dietary zinc increases, the total amount of absorbed zinc increases while the percent absorbed declines. The gastrointestinal tract maintains whole-body zinc homeostasis by adjusting endogenous zinc losses to the amount absorbed. At intakes below about 9 mg/day, zinc absorption occurs primarily by a saturable (carrier) process involving ZIP4, ZnT1, and other transporters. There is no evidence that past zinc intakes, or status, influences zinc absorption. Instead, current zinc intake is the chief determinant

Abstract:

Evidence of absorptive or secretory ion transport in different respiratory regions of the mouse was sought by assessing the regional distribution of α-, β-, and γ-epithelial sodium channel (ENaC; Na+ absorptive), cystic fibrosis transmembrane conductor regulator (CFTR), and Na+-K+-2Cl− cotransporter mRNAs. High levels of ENaC subunit expression were found in nasal surface epithelium and gland ducts. CFTR was expressed in both superficial nasal respiratory epithelium and glands. These results are consistent with basal amiloride-sensitive Na+ absorption and cAMP-dependent Cl− secretion in murine
