Heat Transfer in Aerospace Applications

DescriptionHeat Transfer in Aerospace Applications is the first book to provide an overall description of various heat transfer issues of relevance for aerospace applications. The book contains chapters relating to convection cooling, heat pipes, ablation, heat transfer at high velocity, low pressure and microgravity, aircraft heat exchangers, fuel cells, and cryogenic cooling systems.Chapters spe

High resolution C1s and S2p photoelectron spectra of thiophene

Using high-resolution synchrotron-radiation-based electron spectroscopy, vibrationally resolved C1s and S2p photoelectron spectra were obtained for the thiophene molecule in the gas phase. The vibrational structures were analyzed in terms of normal modes, and lifetimes were determined for the hole states. This complete analysis enabled to determine the binding energies of the chemically shifted ca

Opportunities and Challenges of a Small State Presidency: The Estonian Council Presidency 2017

This article discusses some of the opportunities and challenges that the Estonian Council Presidency is facing during its first term in 2017. We also explore how Estonia is likely to appreach this position. The Council presidency provides a position to propagate national interests and an opportunity for leadership within the Council but can also be preceived as a silencer of domestic narrative. We

Role of cyclin-dependent kinase 2 in the progression of mouse juvenile cystic kidney disease

A hallmark of polycystic kidney diseases (PKDs) is aberrant proliferation, which leads to the formation and growth of renal cysts. Proliferation is mediated by cyclin-dependent kinases (Cdks), and the administration of roscovitine (a pan-Cdk inhibitor) attenuates renal cystic disease in juvenile cystic kidney (jck) mice. Cdk2 is a key regulator of cell proliferation, but its specific role in PKD r

Inhibitor incidence in an unselected cohort of previously untreated patients with severe haemophilia B : a PedNet study

The incidence of FIX inhibitors in severe hemophilia B (SHB) is not well defined. Frequencies of 3-5% have been reported but most studies to date were small, including patients with different severities, and without prospective follow-up for inhibitor incidence. Study objective was to investigate inhibitor incidence in patients with SHB followed up to 500 exposure days (ED), the frequency of aller

Graphene-based plasmonic nanocomposites for highly enhanced solar-driven photocatalytic activities

High-efficiency photocatalysts are crucial for the removal of organic pollutants and environmental sustainability. In the present work, we report on a new low-temperature hydrothermal chemical method, assisted by ultrasonication, to synthesize disruptive plasmonic ZnO/graphene/Ag/AgI nanocomposites for solar-driven photocatalysis. The plasmonic nanocomposites were investigated by a wide range of c

Association between serum concentrations of perfluoroalkyl substances (PFAS) and expression of serum microRNAs in a cohort highly exposed to PFAS from drinking water

BACKGROUND: Perfluoroalkyl substances (PFAS) are widespread synthetic substances with various adverse health effects. Not much is known about the modes of action of PFAS toxicity, but one likely mechanism is alteration of microRNA expression.OBJECTIVES: To investigate whether PFAS exposure is associated with altered microRNA expression in serum.METHODS: We selected women from the Ronneby cohort, w

Electromagnetic form factors of the transition from the spin-3/2 Σ to the Λ hyperon

The three electromagnetic form factors for the transition from a 3/2+Σ∗ hyperon to the ground-state Λ hyperon are studied. At low energies, combinations of the transition form factors can be deduced from Dalitz decays of the Σ∗ hyperon to Λ plus an electron-positron pair. It is pointed out how more information can be obtained with the help of the self-analyzing weak decay of the Λ. In particular,

Advantage of new ventilation method for cardiopulmonary resuscitation qualitatively captured by simple respiratory mechanics models

First responders to cardiac arrest depend on cardiopulmonary resuscitation to keep patients alive. A new ventilation method, phase-controlled intermittent insufflation of oxygen, was previously shown to improve heart perfusion during cardiopulmonary resuscitation in a large-animal study, outperforming the best currently known ventilation method. This paper investigates whether the advantage of the

Ultrasmall TPGS-PLGA Hybrid Nanoparticles for Site-Specific Delivery of Antibiotics into Pseudomonas aeruginosa Biofilms in Lungs

Inhaled antibiotic treatment of cystic fibrosis-related bacterial biofilm infections is challenging because of the pathological environment of the lungs. Here, we present an "environment-adaptive" nanoparticle composed of a solid poly lactic-co-glycolic acid (PLGA) core and a mucus-inert, enzymatically cleavable shell of d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) for the site-specifi

The design of a trimodal broadside antenna element for compact massive MIMO arrays : Utilizing the Theory of Characteristic Modes

Massive multiple-input multiple-output (MIMO) arrays are becoming critical elements in cellular base station infrastructure. We utilize the theory of characteristic modes (TCM) to design a novel tri-modal broadside antenna element which is suitable for the construction of compact massive MIMOarrays. The proposed antenna element consists of three ports which is formed by reviewing an existing compa

Regulation of fungal decomposition at single-cell level

Filamentous fungi play a key role as decomposers in Earth’s nutrient cycles. In soils, substrates are heterogeneously distributed in microenvironments. Hence, individual hyphae of a mycelium may experience very different environmental conditions simultaneously. In the current work, we investigated how fungi cope with local environmental variations at single-cell level. We developed a method based

The feasibility of using Pareto fronts for comparison of treatment planning systems and delivery techniques

Pareto optimality is a concept that formalises the trade-off between a given set of mutually contradicting objectives. A solution is said to be Pareto optimal when it is not possible to improve one objective without deteriorating at least one of the other. A set of Pareto optimal solutions constitute the Pareto front. The Pareto concept applies well to the inverse planning process, which involves
