Comparison of Performance and Effectiveness of Vertical Borehole Heat Exchanger Collectors

The number of heating and cooling system using vertical borehole heat exchangers is increasingly rapidly in Sweden. Currently, there are over 600,000 installations, mostly using U-tube ground collectors. In recent years, several new ground collectors with innovative designs and configurations have been launched. They claim to have superior performance and competitive advantages over the convention

Hemogenic Reprogramming of Human Fibroblasts by Enforced Expression of Transcription Factors

The cellular and molecular mechanisms underlying specification of human hematopoietic stem cells (HSCs) remain elusive. Strategies to recapitulate human HSC emergence in vitro are required to overcome limitations in studying this complex developmental process. Here, we describe a protocol to generate hematopoietic stem and progenitor-like cells from human dermal fibroblasts employing a direct cell

Natural sources and experimental generation of bioaerosols : Challenges and perspectives

Experimental aerosol generation methods aim to represent natural processes; however, the complexity is not always captured and unforeseen variability may be introduced into the data. The current practices for natural and experimental aerosol generation techniques are reviewed here. Recommendations for best practice are presented, and include characterization of starting material and spray fluid, r

Assessing barriers to reuse of electrical and electronic equipment, a UK perspective

This paper reports on research undertaken to identify generic and specific barriers to reuse of electrical and electronic equipment (EEE). Thirty semi-structured interviews were conducted with experts from across the value chain including product designers, manufacturers, users and waste managers as well policy makers and academics. The interviews sought to examine perceived and real barriers to r

Mobile geriatric teams – A cost-effective way of improving patient safety and reducing traditional healthcare utilization among the frail elderly? A randomized controlled trial

Background: Demographic changes combined with costly technological progress put a financial strain on the healthcare sector in the industrialized world. Hence, there is a constant need to develop new cost-effective treatment procedures in order to optimize the use of available resources. As a response, the concept of a Mobile Geriatric Team (MGT) has emerged not only nationally but also internatio

Working on the boundaries—How do science use and interpret the nature-based solution concept?

Nature-based solutions (NBS) is the latest contribution to the green concept family. NBS is defined as actions based in nature addressing societal challenges. In this study, we lean on the concept boundary object, broken down into three analytical categories: use, core ideas and granularities, to explore the cohesive and fragmenting powers of the NBS concept, and discuss its future role in green s

Genomics and epidemiology for gastric adenocarcinomas (GE4GAC): a Brazilian initiative to study gastric cancer

Gastric cancer (GC) is the fifth most common type of cancer worldwide with high incidences in Asia, Central, and South American countries. This patchy distribution means that GC studies are neglected by large research centers from developed countries. The need for further understanding of this complex disease, including the local importance of epidemiological factors and the rich ancestral admixtu

Factors regulating the coastal nutrient filter in the Baltic Sea

The coastal zone of the Baltic Sea is diverse with strong regional differences in the physico-chemical setting. This diversity is also reflected in the importance of different biogeochemical processes altering nutrient and organic matter fluxes on the passage from land to sea. This review investigates the most important processes for removal of nutrients and organic matter, and the factors that re

Silicon sieve electrodes for neural implants - in vitro characterization & in vivo recordings

An in vitro model was developed to characterize the electrical properties of silicon microfabricated recording electrodes, using a Cu-wire mimicing a neural signal source. Phosphorous doped electrodes were used to achieve an all silicon device. The model was used to study signal amplitude as a function of distance between the electrode surface and the signal source. Signal crosstalk to neighbourin

A comparative cost analysis of conventional wrought steel and powder metallurgy (PM) gear manufacturing technologies

The transportation industry landscape is going through a massive transformation due to trends such as autonomous and electrified vehicles. The electrification trend has already started to display its ample influence on the automotive industry. New modern power and drivetrains need to be designed and manufactured based on the raising automakers’ requirements e.g. higher performance, better noise vi

A Convivial Journey : From Diversity in Istanbul to Solidarity with Refugees in Denmark

This chapter presents my analytical journey from conviviality, a concept used for analysing diversity in Istanbul to overcome the pitfalls of multiculturalism and coexistence theories, to the development of the concept of convivial solidarity for the analysis of transnational civil society organisations that support refugees and migrants in Denmark. Convivial solidarity is my construct and I use i

Parents’ and children’s involvement in decision-making during hospitalisation.

Different reasons are given as to why children and their parents should be involved in discussions and decisions regarding the child’s care. The UN Convention on the Rights of the Child formulates the needs of children and young people in terms of human rights. Ethical duties of health professionals include the obligation to enhance their patients’ competence and ability to participate. The concep

Effect of the addition of thermostable and non-thermostable type 2 resistant starch (RS2) in cake batters

There is interest in increasing the consumption of foods with high dietary fiber content due to the health problems associated with its low intake. Plantain (Musa paradisiaca L.) flour (PF) (non-thermostable) and Hi-Maize 260 (HA) (thermostable) were used as resistant starch (RS) sources to elaborate blends with wheat (WF) and rice flours (RF) in a 50:50 ratio. Five blends were prepared (PF-WF, PF

Influence of root distribution on preferential flow in deciduous and coniferous forest soils

Root-induced channels are the primary controlling factors for rapid movement of water and solute in forest soils. To explore the effects of root distribution on preferential flow during rainfall events, deciduous (Quercus variabilis BI.) and coniferous forest (Platycladus orientalis (L.) Franco) sites were selected to conduct dual-tracer experiments (Brilliant Blue FCF and Bromide [Br-]). Each plo

Trade in Services in the New Century

Concerns have been raised about the potential adverse effects of liberalizing trade in services under the GATS framework on equity, costs, distribution, availability of services and sovereignty of governments in defining their national objectives. These concerns have been voiced in poor countries in case of such social service sectors as health and education. Critics have stressed the need for an
