This study tested the hypothesis that exhaled ethane is a biomarker of cerebral n-3 polyunsaturated fatty acid peroxidation in humans. Ethane released specifically following acids. We reasoned source would be docosahexaenoic component membrane phospholipids. Breakdown latter also releases phosphorylated polar head groups, giving rise to glycerophosphorylcholine and glycerophosphorylethanolamine, which can measured from 31-phosphorus neurospectroscopy phosphodiester peak. Schizophrenia...
The aim was to carry out the first voxel-based morphometry study of grey matter changes in whole brain schizophrenia associated with a history seriously and violently offending.Structural cerebral magnetic resonance imaging scans 26 patients were analyzed using morphometry: 13 had offended directly as result prior admission, offences consisting homicide, attempted murder or wounding intent cause grievous bodily harm; other did not have violence. There no comorbid psychoactive substance...
Horizontal curves on road are commonly analyzed under design speed point of view, where it is assumed that the maximum a vehicle in curve speed. The empirical evidence has demonstrated when low, operating tends to be higher. This happens because an available remaining lateral (or transverse) friction for speeds over condition determined by limit, obtained from demand and supply equilibrium pavement. difference between usually considered as margin safety horizontal road. In this study,...
This paper presents the main results of a calibration distress models from Mechanistic–Empirical Pavement Design Guide (MEPDG) to local conditions in Argentina be used rigid pavement structural design. Test sections with pavements were selected cover wide range climatic central region country. Local road agencies provided information about structure, traffic volume, and load spectra. Field data international roughness index (IRI) values collected processed MEPDG software; factors determined...
Gravel roads are an important portion of the road network in western Argentina, and their maintenance requires a huge amount economic human resources. Recently, use alternative treatments based on application mineral salts such as hydrous magnesium chloride, also known bischofite, has been introduced this region. Such being applied for dust control surface stabilization unpaved roads. This paper presents main results obtained during research project carried out by National University San...
A methodology for calibrating performance models jointed plain concrete pavements (JPCP) is presented; it based on statistical analysis of data from the Long-Term Pavement Performance (LTPP) database. The provides calibration factors to in four climatic regions (dry-freeze, dry-nonfreeze, wet-freeze, and wet-nonfreeze) JPCP HDM-4: joint faulting, transverse cracking, spalling, roughness. procedure allows calculation global factors, which does not affect significantly quality prediction...

Portland cement concrete pavements have been constructed in many areas Argentina that feature heavy traffic and freeways highways freezing areas. To predict their performance, computational programs such as the World Bank's HDM-4 may be used. This particular software includes distress models need to adjusted local conditions order optimize evaluation of maintenance strategies resource allocation. The main objective this study is evaluate performance midwestern region by using obtain...
Objective: Initial phosphorus magnetic resonance spectroscopy observations on the oxygen metabolism of placental villi from normal term pregnancies are described.Study Design: Villi were suspended in medium and perifused within a custom-designed 30 mm nuclear probe superconducting vertical magnet where pH, temperature, oxygenation monitored.Results: Phosphorus resonances observed adenosine triphosphate, phosphomonoesters, inorganic phosphate, phosphodiesters. No phosphocreatine signal was...

Concrete is widely used as a construction material in pavements by public and private agencies that administer highway networks because of its high durability capacity to resist large traffic loads very rigorous climates. Nevertheless, these have estimate the evolution pavement performance plan optimize application adequate maintenance activities, allowing be maintained at an optimum service level throughout lifetime. Predictive distress models incremental type, is, capable predicting annual...
