Experimental investigation on convective heat transfer of ferrofluids inside a pipe under various magnet orientations

Some experimental tests were conducted to reveal the enhancement of the ferrofluid heat transfer under a permanent magnetic field. This research aims to investigate the effect of various external magnetic fields on convective heat transfer characteristics of the ferrofluid (magnetic nanofluid). Comparison of theoretical predictions and experimental data were conducted to validate the rationality o

The mining sectors in Chile and Norway from approximately 1870 to 1940 : the development of a knowledge gap

Chile and Norway are two ‘natural resource-intensive economies’, which have had different development trajectories, yet are closely similar in industrial structure and geophysical conditions. This paper seeks to contribute to the debate about how and why some economies based on natural resource activities have been more dynamic and innovative than others by indicating contributing factors of key d

This article discusses the violations committed by every party in the civilian war in Yemen, because there is no any accountability from the international community against those who committed these crimes.

Metabolic Activity of Lymphoma Cells and Clinical Course in Non‐Hodgkin Lymphoma (NHL)

By microcalorimetry the metabolic activity of malignant cells from 21 patients with non‐Hodgkin lymphoma was monitored. Heat production, a measure of the metabolic activity of cells, showed positive correlation with the clinical‐course of the disease. The heat produced by tumor cells from patients with progressive disease was 5.5 pW/cell, while that from patients responding to treatment was 3.1 pW

Immunoglobulin-A producing probably primary lymphoma of the breast

A breast tumour from a 65-year old woman was found to be a primary non-Hodgkin lymphoma, a very rare primary malignancy in this location. The lymphoma was of a diffuse histiocytic type according to the classification of Rappaport, or polymorphic immunocytoma according to the Kiel classification. Immunohistochemistry, not previously reported for breast lymphomas, revealed the production of IgA. In

Treaty Abuse, General International Law, and the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent BEPS: What Can Be Achieved by Applying the Multilateral Convention That Cannot Already Be Achieved by Applying General International Law?

The concept of treaty abuse, although being of great significance to the operation of international tax treaties, is by no means peculiar to this particular branch of law. A treaty abuse doctrine exists in general international law since long. As this paper argues, current work within the OECD, and especially the existence of the recently negotiated Multilateral Convention to Implement Tax Treaty

While all institutions are silent toward the war and crime in yemen, we can see the free journalistic institution can play a positive role to fight against violations.

Effects of starch granules differing in size and morphology from different botanical sources and their mixtures on the characteristics of Pickering emulsions

The aim of this work was to investigate how mixtures of starch granules of different size and shape from different botanic sources affect starch-stabilized Pickering emulsions, and to understand which type of granules that dominate at the interface of the emulsion droplets. Pickering emulsions were prepared by combining quinoa starch with waxy maize or oat starch. The effects of the individual sta

Salt-Induced Universal Slowing Down of the Short-Time Self-Diffusion of a Globular Protein in Aqueous Solution

The short-time self-diffusion D of the globular model protein bovine serum albumin in aqueous (D2O) solutions has been measured comprehensively as a function of the protein and trivalent salt (YCl3) concentration, noted cp and cs, respectively. We observe that D follows a universal master curve D(cs,cp) = D(cs = 0,cp) g(cs/cp), where D(cs = 0,cp) is the diffusion coefficient in the absence of salt

Storylines : an alternative approach to representing uncertainty in physical aspects of climate change

As climate change research becomes increasingly applied, the need for actionable information is growing rapidly. A key aspect of this requirement is the representation of uncertainties. The conventional approach to representing uncertainty in physical aspects of climate change is probabilistic, based on ensembles of climate model simulations. In the face of deep uncertainties, the known limitation

Conceptualizing multiple drug use in patients with comorbidity and multimorbidity : proposal for standard definitions beyond the term polypharmacy

With older and aging populations, patients experience multiple chronic diseases at the same time. Individual chronic disease guidelines often recommend pharmacological therapies as a key intervention, resulting in patients being prescribed multiple regular medications for their different diseases. Although the term “polypharmacy” has been applied to the use of multiple medications, there is no con

Multi-User Processing for Ray-Based Channels

The performance of linear multi-user multiple-input multiple-output (MU-MIMO) systems has been extensively studied for classical statistical channel models. In contrast, there is little analysis for ray-based models, which are physically motivated, feature prominently in standards and have been experimentally validated. Thus, we present a novel analysis framework for zero forcing (ZF) and maximal

Swedish Economists in the 1930s Debate on Economic Planning

The 1930s, characterised by repercussions from World War I and the Great Depression, was an era of populism, nationalism, protectionism, government intervention and attempts to create planned economies. The perceived need for economic planning emerged in Sweden in part due to the increasing political strength of the Social Democrats and their evolution from a party hampered by Marxist fatalism to
