Two-year trials (20062007) suggested that the use of calcium oxide (CaO) on acid soils increased soil pH and yields in strawberry cultivars Marmolada, Selena and Senga Sengana, under the environmental conditions of Cacak (Western Serbia). The highest yield was obtained when CaO was applied at 750 kg ha-1 rate. Further increase in rate up to 1,500 kg ha-1 did not show corresponding increase in y...

We are investigating the cooperative behavior of intelligent agents in a large group. A cooperative intelligent agent is a user's personal consultant that can take care of problems the user got, and solve them either by itself or via cooperation. We have proposed a twin-base (cooperator-base U task-base) agent modeling technique for individual agents to monitor activities of the others in order...

The extent to which the blood supply of normal and hypertrophied right ventricles originates from the right and left coronary arteries was investigated in conscious dogs. Right ventricular (RV) hypertrophy, induced by gradual, chronic (4-6 months) stenosis of the main pulmonary artery, was characterized by a 72% increase (P < 0.001) in RV weight to body weight ratio and a 106% increase (P < 0.0...

Background Emphysema is a distinct feature for classifying COPD, and smoking history (≥10 pack-years) is one of several newly proposed criteria for asthma-COPD overlap (ACO). We studied whether or not a smoking history (≥10 pack-years) and emphysema are useful markers for classifying ACO and differentiating it from asthma with chronic airflow obstruction (CAO). Methods We retrospectively stud...

BACKGROUND Cerebral blood flow (CBF) is auto-regulated to meet the brain's metabolic requirements. Oxycyte is a perfluorocarbon emulsion that acts as a highly effective oxygen carrier compared to blood. The aim of this study is to determine the effects of Oxycyte on regional CBF (rCBF), by evaluating the effects of stepwise isovolemic hemodilution with Oxycyte on CBF. METHODOLOGY Male rats we...

BACKGROUND Mitochondrial dysfunction is critical following ischemic disorders. Our goal was to determine whether mild hypothermia could limit this dysfunction through per-ischemic inhibition of reactive oxygen species (ROS) generation. METHODS First, ROS production was evaluated during simulated ischemia in an vitro model of isolated rat cardiomyocytes at hypothermic (32°C) vs. normothermic (...

This paper addressed the application of new hydrophobic synthesized calcium oxide (CaO) and silicon dioxide (SiO2) nanofluids to low permeability carbonate porous media. Crude oil and plugs were selected from one of oil reservoirs in the west of Iran. The main goal of this paper is comparing the results of improving water-oil relative permeability parameters in low permeability plugs...

BACKGROUND Patients with advanced non-small-cell lung cancer (NSCLC) and acute respiratory failure (ARF) from central airway obstruction (CAO) may be offered end-of-life care rather than intensive care treatment and palliative bronchoscopic intervention. OBJECTIVES To determine whether bronchoscopic intervention could be immediately successful in restoring airway patency and obviate the need ...

This work illustrates a comparative study on the applicability of the basic heterogeneous calcium oxide catalyst prepared from waste mollusks and crabs shells (MS and CS, resp.) in the transesterification of waste cooking oil collected from seafood restaurants with methanol for production of biodiesel. Response surface methodology RSM based on D-optimal deign of experiments was employed to stud...
