The polycondensation of polyesters from C-12 monomers at 95 degrees C in aqueous o/w emulsions, stabilized by acidic surfactants, has been studied in detail with a range of methods during the course of the reaction, resulting in a better understanding of the underlying reaction mechanisms. Comparisons of different surfactants, and effects of added NaCl, demonstrate that the reaction site is locate
Preeclamptic women have increased plasma levels of free fetal hemoglobin (HbF), increased gene expression of placental HbF and accumulation of free HbF in the placental vascular lumen. Free hemoglobin (Hb) is pro-inflammatory, and causes oxidative stress and tissue damage.
The third meeting of the International Society for Holter and Noninvasive Electrocardiology working group was convened in Lund, Sweden, in June 2010 to consider the key clinical challenge of developing electrocardiographic (ECG) criteria for identification of the global subendocardial ischemia that results from subtotal occlusion of either the left main coronary artery or its equivalent. The parti
In this work the effect of a partial replacement of CaH2 with CaF2 on the sorption properties of the system CaH2 + MgB2 has been studied. The first five hydrogen absorption and four desorption reactions of the CaH2 + MgB2 and 3CaH(2) + CaF2 + 4MgB(2) systems were investigated by means of volumetric measurements, high-pressure differential scanning calorimetric technique (HP-DSC), B-11 and 19F MAS
Abstract in UndeterminedPhysicochemical properties of cereal beta-glucans, associated with beneficial health effects, are related to their solution behavior and possibly to their propensity to form aggregates. Such properties are often analyzed with methods that may influence the aggregates per se. In this paper, the effect of processing on solution behavior of pure barley b-glucan was studied usi
Life threatening arrhythmias are increasingly frequent with lower body temperature. While targeted temperature management (TTM) with mild hypothermia following out-of-hospital cardiac arrest (OHCA) is generally considered safe and has been suggested as a potential antiarrhythmic add-on therapy, it is unknown whether the level of TTM affects the burden of ventricular ectopic activity. We sought to
This paper describes a hardware efficient linear pre-coder for Massive MIMO Base Stations (BSs) comprising a very large number of antennas, say, in the order of 100s, serving multiple users simultaneously. To avoid hardware demanding direct matrix inversions required for the Zero-Forcing (ZF) pre-coder, we use low complexity Neumann series based approximations. Furthermore, we propose a method to
Stomatopod crustaceans, or mantis shrimp, are renowned for their complex visual systems. Their array of 16 types of photoreceptors provides complex color reception, as well as linear and circular polarization sensitivity [1-6]. The least-understood components of their retina are the UV receptors, of which there are up to six distinct, narrowly tuned spectral types [4]. Here we show that in the sto
A previous paper addressed the "PI+p" controller (a PI augmented with an additional, stable pole) and demonstrated its advantages over standard PIs, particularly if tuned with a combined model-relay-based method along the "contextual" approach proposed in another recent work. This manuscript extends the scenario to the PID+p structure, with obvious meaning, and applies the contextual approach to i
The practices around genetic testing for hereditary breast and ovarian cancer in one major counselling centre in Austria are at the core of this article. Our study investigates how people undergoing genetic testing try to make sense of this experience that is perceived to be new and uncommon in Austria and that is thus taking place in a setting not validated through public insurance support and is
Mechanical stimuli such as tissue deformation and fluid flow are often implicated as regulators of mesenchymal stem cell (MSC) differentiation during regenerative events in vivo. However, in vitro studies have identified several other physical and biochemical environmental cues, such as substrate stiffness and oxygen availability, as key regulators of stem cell fate. Hypotheses for how MSC differe
To investigate differences and similarities in person-environment (P-E) fit problems between very old people with self-reported Parkinson's disease (PD) and matched controls.
The performance of InGaAs metal oxide semiconductor field effect transistors with Al2O3 or HfO2 as gate oxide is evaluated and compared. The Al2O3 transistors show the lowest subthreshold slope and mid gap D-it, however, the HfO2 transistors reach a higher maximum transconductance (g(max)) due to the higher oxide capacitance. Both high-kappa dielectrics show a g(m)-frequency dispersion due to tunn
Injection drug users (IDUs) are at increased risk of various medical conditions, including bacterial skin and soft tissue infections (SSTIs). SSTIs, which are painful and can lead to life-threatening complications, are common but scarcely studied.
We study the few-body physics of trapped atoms or molecules with electric or magnetic dipole moments aligned by an external field. Using exact numerical diagonalization appropriate for the strongly correlated regime, as well as a classical analysis, we show how Wigner localization emerges with increasing coupling strength. The Wigner states exhibit nontrivial geometries due to the anisotropy of th
Research on dementia care settings has primarily focused on routine aspects of life, including mealtimes, bathing procedures, etc. However, studies rarely explore how individuals with dementia interact in these settings during the intervals between routines. This study aimed to analyze how residents actively carved out spaces that provided temporary respite from institutional life, termed “framing
The number concentration of cloud droplets determines several climatically relevant cloud properties. A major cause for the high uncertainty in the indirect aerosol forcing is the availability of cloud condensation nuclei (CCN), which in turn is highly sensitive to atmospheric new particle formation. Here we present the effect of new particle formation on anthropogenic aerosol forcing in present-d
