A 3D model at microscale by the lattice Boltzmann method (LBM) is proposed for part of an anode of a solid oxide fuel cell (SOFC) to analyze the interaction between the transport and reaction processes and structural parameters. The equations of charge, momentum, heat and mass transport are simulated in the model. The modeling geometry is created with randomly placed spheres to resemble the part o

Mesenchymal stem or stromal cells (MSCs), a heterogeneous subset of adult stem/progenitor cells, have surfaced as potential therapeutic units with significant clinical benefit for a wide spectrum of disease conditions, including those affecting the lung. Although MSCs carry both self-renewal and multilineage differentiation abilities, current dogma holds that MSCs mainly contribute to tissue regen

Intercalated composite materials were prepared with CaAl-layered double hydroxide as the host and Mn(II)-amino acid (l-cysteine, l-histidine and l-tyrosine) complex anions as the guest. Two methods (intercalation of the ligand first followed by constructing the complex; preforming the complex first, then introducing it among the layers of the host) and optimization of the auxiliary conditions were

The paper elaborates and tests two hypotheses. First, that knowledge is not a homogeneous activity, but rather a bundle of highly differentiated disciplines that have different characteristics, both in terms of generation and exploitation, that bear a differentiated impact on economic growth. Advances in scientific knowledge that can be converted into technological knowledge with high levels of fu

Gaza has several water problems; limited fresh water supply, inefficient water use by the agricultural sector, high water demand, groundwater contamination, seawater intrusion and shortage of electricity. Water and electricity is the first priority for Gaza that will add significant positive values to the Palestinians living in blocked Gaza and easy operation and maintenance of their ongoing and e

From an airstrip in Saudi Arabia, the CIA launches drones to 'legally' kill Al-Qaida leaders in Yemen. On the North Pole, Russia plants a flag on the seabed to extend legal claim over resources. In Brussels, the European Commission unveils its Emissions Trading System, extending environmental jurisdiction globally over foreign airlines. And at Frankfurt Airport, a father returning from holiday is

Broadband circuit models for electric machines are effective means to understand, predict, and control the phenomenon of conducted Electromagnetic Interference (EMI) from immunity/susceptibility perspective. These models should cover the capacitive and inductive coupling behavior of the component along the frequency range of interest. Circuit models used under generic SPICE simulation softwares ar

According to the ontological stance adopted in this essay, a concept is a mental representation. It is the generalized idea of an empirical or normative phenomenon or state of affairs or a class of such phenomena or state of affairs. This essay is concerned with a specific category of concepts typically referred to as “concepts of international or international law” or “international legal concept

We report here on a diagnostic tool for improving doctoral supervision that supervisors in training at Lund University use to develop strategies for supporting their student’s learning. The tool has been developed by combining two theoretical models, an empirically generated model of orientations to doctoral supervision (Lee, 2008) and a meta-perspective on professional learning (Dall'Alba & S

The paper is concerned with coordinate representations for rigid parts in multibody dynamics. The discussion is based on the general theory of the dynamics of multibody systems under constraints. General configuration coordinates are introduced and the requirement of their regularity is discussed. The use of Euler angles, quaternions and linear coordinates, where quaternions and linear coordinates

Ethnography is a very abstract concept, but often perceived as a very concrete practice, but what is hidden in the slippage between the abstract and concrete, as ethnography moves. While a great deal has been written and debated about the practices, methods and outcomes of applied research, and we appreciate these debates, our own point of departure lies in a curiosity over what happens in the pro

Intercalated composite materials were prepared with CaAl-layered double hydroxide as host and Cu(II)-amino acid (L-cysteine, L-histidine and L-tyrosine) complex anions as guests. Two methods (intercalation of the ligand first followed by constructing the complex; preforming the complex first, then introducing it among the layers of the host) and optimization of the synthesis conditions were perfor

Recent literature has suggested how late-medieval families may have used financial markets to navigate the life cycle. Precious little is known about the precise connections between the life cycle and family on the one hand and investments in financial instruments on the other, though. We analyse late-medieval investment behaviour using a new dataset of hundreds of life annuities. Our data give ag

A model is developed to simulate the cross-shore (CS) exchange of sand and the resulting profile response at decadal scale to be used in regional coastal evolution models. The CS model consists of modules for calculating dune erosion and overwash, wind-blown sand transport, and bar-berm material exchange. The sand transport equations included in these modules are formulated based on relevant physi

The ability to form long-term memories exists very early during ontogeny; however, the properties of early memory processes, brain structures involved and underlying cellular mechanisms are poorly defined. Here, we examine the role of extracellular signal-regulated kinase (ERK), a member of the mitogen-activated protein kinase/ERK signaling cascade, which is crucial for adult memory, in the consol

Det är sen länge känt att de proteiner som utför cellernas funktioner mestadels inte är oberoende och enskilda, utan sitter ihop i proteinkomplex. Förståelsen om hur dessa komplex ser ut och sitter ihop är väsentlig för att till exempel kunna avgöra deras funktion eller förstå hur strukturändringar från sjukdomar och mutationer kan påverka dem. Bestämning av strukturerna på proteinkomplex brukar g

Ordinära differentialekvationer används ofta inom naturvetenskapliga ämnen för att modellera fysiska fenomen. Lösningarna till dessa ekvationer är deterministiska i den mening att vi alltid vet var ett system kommer hamna i framtiden givet ett startvillkor. I denna uppsats studerar vi teorin bakom så kallade stokastiska differentialekvationer (SDE), vilka uppstår genom att lägga till slumpmässigt In this master's thesis we study stochastic integration in three parts --- through continuous semimartingales, Föllmer's deterministic $p$-variational Ito calculus, and rough path theory --- to answer the question whether stochastic integrals can be formulated as pathwise limits instead of limits in probability. The first part covers everything from discrete martingales to stochastic diffe
