According to a dominant view, the approximate number system (ANS) is the foundation of symbolic math abilities. Due to the importance of math abilities for education and career, a lot of research focuses on the investigation of the ANS and its relationship with math performance. However, the results are inconsistent. This might be caused by studies differing greatly regarding the operationaliza...

We suggest a theoretical method for dealing with the contribution of phasons to the lattice vibration of quasicrystals. Based on this, we derive the density of vibrational states ~DOVS! and specific-heat expressions of the icosahedral Al-Mn-Pd quasicrystal, and obtain corresponding numerical solutions which are in agreement with the experimental data measured by Wälti et al. @Phys. Rev. B 57, 1...

Background Spread hepatic tumours are not suitable for treatment either by surgery or conventional ablation methods. The aim of this study was to evaluate feasibility and safety of selectively increasing the healthy hepatic conductivity by the hypersaline infusion (HI) through the portal vein. We hypothesize this will allow simultaneous safe treatment of all nodules by irreversible electroporat...

The thick ascending limb of the loop of Henle (THAL) plays an essential role in the regulation of sodium and water homeostasis by the kidney. l-Arginine, the substrate for nitric oxide synthase (NOS), decreases NaCl absorption by THALs. We hypothesized that eNOS produces the NO that regulates THAL NaCl transport and that selective expression of eNOS in the THAL of eNOS knockout(-/-) mice would ...

The effect of a tryptic hydrolysis as well the ionic strength (0–0.4 M NaCl) was investigated on oil/water interfacial properties soluble pea protein hydrolysate (SPPH) at neutral pH and room temperature (20 ± 0.01 °C). SEC-MALS SDS-Page analysis showed that created lower molecular weight polypeptide mixture, whereas FTIR DSC thermograms demonstrated more disordered flexible structure. bulk SPP...

The thick ascending limb of the loop of Henle (THAL) plays an important role in the regulation of NaCl and water reabsorption. In vivo studies have shown that the free radical superoxide (O) stimulates Na and water reabsorption by the kidney. However, it is not known whether O regulates transport along the nephron in general or in the THAL specifically. We hypothesized that O stimulates THAL Na...

Naturforsch. 49c, 615-618 (1994); received May 9/June 8, 1994 Fruit Cuticles, Membrane Potential, Membrane Conductivity, Ionic Permeabilities Membrane potential and electrical resistance for two isolated fruit cuticular membranes (tomato and pepper cutic...

The oxygen reduction reaction (ORR) is one of the major factors that is limiting the overall performance output of microbial fuel cells (MFC). In this study, Platinum Group Metal-free (PGM-free) ORR catalysts based on Fe, Co, Ni, Mn and the same precursor (Aminoantipyrine, AAPyr) were synthesized using identical sacrificial support method (SSM). The catalysts were investigated for their electro...

Samples of surimi were prepared in laboratory conditions from Adriatic pilchard (Sardina pilchardus). Water content in surimi was 81.5% before mixing with NaCl and κ-carrageenan, which were added in the range of mass fraction from 0 to 10%. Relative apparent specific enthalpy !, initial freezing point Ti, density ρ, and thermal conductivity k of surimi in the temperature range from -25 C to 10 ...

The compounds, lanthanium chromite, lanthanium magnetite and lanthanium ferric oxide were prepared through sol-gel methods in powdered form, then calcinated, peletized, and sintered at various temperatures. Electrical conductivity of these compounds was measured at various temperatures. The effectiveness of strontium as a dopant on electrical conductivity was also investigated. Electrical condu...
