We investigated the role of passive volcanic plume Mount Etna (Italy) in formation new particles size range 2.5–10 nm through gas-to-particle nucleation sulfuric acid (H2SO4) precursors, formed from oxidation SO2, and their evolution to with diameters larger than 100 nm. Two simulations were performed using Weather Research Forecasting Model coupled chemistry (WRF-Chem) under same configuration...

The effect of freezing on the properties of a raw ewes'-milk semi-soft cheese (Serpa cheese) was studied using small amplitude oscillatory (SAOS) and texture measurements, colour and chemical parameters. The freezing was introduced at three different stages of the ripening process (28, 35 and 42 days), and the cheeses were maintained frozen for 12 months. Cheeses were submitted to a slow or fas...

We previously demonstrated (M. M. Exner, P. Doig, T. J. Trust, and R. E. W. Hancock, Infect. Immun. 63:1567-1572, 1995) that Helicobacter pylori has at least one nonspecific porin, HopE, which has a low abundance in the outer membrane but forms large channels. H. pylori is relatively susceptible to most antimicrobial agents but less susceptible to the polycationic antibiotic polymyxin B. We dem...

Modified Reconstructibility Analysis (MRA), a novel decomposition within the framework of set-theoretic (crisp possibilistic) reconstructibility analysis, is presented. It is shown that in some cases, while three-variable NPNclassified Boolean functions are not decomposable using Conventional Reconstructibility Analysis (CRA), they are decomposable using MRA. Also, it is shown that whenever a d...

We explore the chiral transmission of electrons across graphene heterojunctions for electronic switching using gate geometry alone. A sequence of gates is used to collimate and orthogonalize the chiral transmission lobes across multiple junctions, resulting in negligible overall current. The resistance of the device is enhanced by several orders of magnitude by biasing the gates into the bipola...

Gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus play an important role in reproductive function. These cells originate in the nasal compartment and migrate into the basal forebrain in association with olfactory/vomeronasal nerves in embryonic life in rodents. Here, we studied the role of neuropilins and their ligands, semaphorins, in the development of the olfactory-GnRH syste...

Improved transport models for quasi-3D circuit-based simulation (Q3DSim) of four-layer devices such as thyristors and transient overvoltage protectors (TOVPs) are presented. Q3DSim is an attractive alternative to full 3D transport equations based simulations (3D-TES), since it is much faster and requires less computer power. In Q3DSim, the thyristor is divided into four-layered square prisms, a...

Lymphocyte reactivity to virulent gonococcal antigen T2 and the non-pathogenic Neisseria pharyngis (NPN) has been studied by using the 14C-thymidine uptake in cell cultures from 42 patients with gonococcal urethritis and from 18 controls. The DNA synthesis in cell cultures with T2 antigen was higher in 21 female patients than in the 18 controls. No differences in DNA synthesis were observed in ...
