An analysis of pool boiling heat transfer on nanoparticle-coated surfaces

In the present study, copper surfaces were deposited with Cu-Zinc nanoparticles of 0.6 mg by an electrophoretic deposition method (EPD). Two deposition patterns were designed, i.e., fully deposition (EPD-F) and channel-pattern deposition (EPD-C). In the channel-pattern deposition, the smooth channel and the deposition channel occur alternatively, by keeping the width of the smooth channel as 3 mm,

Sexual orientation, suicide ideation and suicide attempt : A population-based study

The aim is to investigate associations between sexual orientation and experience of suicide thoughts and suicide attempts. The 2012 public health survey in Scania, southern Sweden, is a cross-sectional population-based study including 28,029 participants aged 18–80 with 51.7% participation. The associations between sexual orientation and experience of suicide thoughts and attempts were investigate

Low 2016/17 season vaccine effectiveness against hospitalised influenza A(H3N2) among elderly : awareness warranted for 2017/18 season

In a multicentre European hospital study we measured influenza vaccine effectiveness (IVE) against A(H3N2) in 2016/17. Adjusted IVE was 17% (95% confidence interval (CI): 1 to 31) overall; 25% (95% CI: 2 to 43) among 65-79-year-olds and 13% (95% CI: -15 to 30) among those ≥ 80 years. As the A(H3N2) vaccine component has not changed for 2017/18, physicians and public health experts should be aware

Understanding processes of path renewal and creation in thick specialized regional innovation systems : Evidence from two textile districts in Italy and Sweden

The type of regional innovation system (RIS) strongly affects possibilities of paths of industrial transformation. This paper argues that traditional manufacturing districts, corresponding to specialized RISs and characterized by various nuclei of specialization and know-how, may foster different trajectories in combination with extra-regional networks. In particular, the paper analyses the interp

Nucleate pool boiling heat transfer of acetone and HFE7200 on copper surfaces with nanoparticle coatings

Nucleate pool boiling performance of two well-wetting liquids, i.e., acetone and HFE7200, on three nanoparticle-coatedsurfaces were experimentally studied and compared with that of the smoothsurface. Electrophoretic deposition was used to fabricate nano-porous surfaces.Surface roughness, static and advancing contact angles, capillarity of the smoothand coated surfaces were characterized. Compared

Experimental Observation of Crystal-Liquid Coexistence in Slit-Confined Nonpolar Fluids

Films of carbon tetrachloride (CCl 4 ) confined in slit geometry between two flat diamond substrates down to a few tens of Angstroms are studied by combining X-ray reflectivity with in-plane and out-of-plane X-ray scattering. The confined films form a heterogeneous structure with coexisting regions of liquid and crystalline phases. The liquid phase shows short-range ordering normal to the surfac

Postoperative complications following colonic resection for cancer are associated with impaired long-term survival

Aim: Surgery for colorectal cancer is associated with a high incidence of postoperative complications. The aim of this study was to analyse whether postoperative complications following radical resection for colorectal cancer are associated with increased recurrence rate and impaired survival. Method: Patients operated for colon cancer between 2007 and 2009 with curative intent were identified thr

Is there such a thing as sustainable agricultural intensification in smallholder-based farming in sub-Saharan Africa? Understanding yield differences in relation to gender in Malawi, Tanzania and Zambia

Smallholder-based, sustainable, agricultural intensification is increasingly put forth as a development pathway that is necessary to improve farmer's livelihoods, enhance productivity and engender a surplus that can be used to feed growing urban areas across sub-Saharan Africa. The following article examines trends in yields for Africa's largest staple crop – maize – among smallholder farmers in s

Modeling and Control Strategies of Proton Exchange Membrane Fuel Cells

In this work, comprehensive mathematical models for polymer electrolyte fuel cells (PEFCs) with three different controllers (PID, FOPID and fuzzy + PID) are developed. The models are designed to control the PEMFCs' output voltage at a determined value by indirectly regulating the input hydrogen mass flow rate. The simulation results show that the developed model is well suitable for characterizing

Diapause decision in the small tortoiseshell butterfly, Aglais urticae

Insects in temperate areas spend the inhospitable winter conditions in a resting stage known as diapause. In species that diapause in the larval or pupal stage, the decision whether to diapause or develop directly is customarily taken during the late instars, with long days (i.e., long light phases) and high temperatures promoting direct development. Among butterflies that overwinter as adults, da

Effect of food intake on 92 oncological biomarkers by the Proseek Oncology II panel

Objective: To evaluates the effect of food intake on 92 oncological biomarkers to evaluate whether the timing of blood sampling could be relevant. Twenty-two healthy subjects were investigated. A total of 92 biomarkers were measured before a standardised meal as well as 30 and 120 min afterwards with the Proseek Multiplex Oncology II kit. Results: The levels of 6 biomarkers decreased significantly

The impact of parental death on the timing of first marriage: Evolutionary versus social explanations (The Netherlands, 1850–1940)

Background: This article examines the impact of parental death in childhood, adolescence, and adulthood on male and female age at marriage in the Netherlands in the period 1850–1940. It follows an interdisciplinary approach as it considers explanations based on social and demographic history and evolutionary biology.Objective: We study the classical historical framework in more detail by controlli

Energy Embodied in Trade, 1970–2014

Ongoing globalisation combined with the rapid pace of technological change have generated significant growth in economic activities and have improved the welfare and living standards of many people around the world. e opening up of the world economy has also led to unprecedented surges in international trade and has fundamentally transformed the way that goods and services are produced, exchanged

IgE sensitization in a cohort of adolescents in southern Sweden and its relation to allergic symptoms

Background: There is a strong and consistent association between IgE sensitization and allergy, wheeze, eczema and food hypersensitivity. These conditions are also found in non-sensitized humans, and sensitization is found among individuals without allergy-related diseases. The aim of this study was to analyse the sensitization profile in a representative sample of the population, and to relate pa
