Determination of the effects of bioethanol-diesel fuel blends containing Beraid ED10 additive on engine performance and emissions in a diesel engine with a pump injection system
In the present study, the effects of bioethanol-diesel fuel- Beraid ED10 additive blends on engine performance and emissions were investigated on a four-stroke, three-cylinder, water-cooled, turbocharged diesel engine with a pump injection fuel system. Low-sulphur Eurodiesel fuel, BE5 (5% bioethanol – 93% euro diesel – 2% Beraid ED10), BE10 and BE15 fuels were used in the experiments. The changes...

Efficacy of imidacloprid (Confidor 200SL) and improved cultural practices in the control of the green date palm pit scale insect (Asterolecanium phoenicis Rao.) (Palmapsis phoenicis) (Homoptera: Asterolecaniidae) in Northern Sudan
Experiments were undertaken in Elgaba scheme for two seasons (1999/2000 and 2000/2001) to evaluate the efficacy of imidacloprid (as Confidor 200SL) as part of a technical cultural practices package (earthing, pruning and regular irrigation) in the control of the date palm green pit scale insect Asterolecanium phoenicis (Rao). Four doses of Confidor 200SL (15, 20, 25 and 35 ml/palm) were compared...

Constraint models for the bandwidth minimization problem
The satisfiability problem (SAT) is a well studied problem in logic which searches for a truth assignment of a set of Boolean variables that evaluates a specific formula to true. The bandwidth minimization problem for graphs (BMPG) is a well studied problem in graphs and requires finding the labels of the nodes of a graph such that the maximum absolute difference among neighbors is minimized. This paper...

Barley grain yield path analysis (Hordeum disticum L.) in dry regions of Iran
In order to determine the correlation and relationship between the grain yield and other important traits in 24 genotypes of barley, an experiment was conducted in Dry Land Research Station of Shirvan. The experimental design was a randomized complete block with three replications. The evaluated traits were grain yield, days to emergence, days to heading, days to maturity, plant height, plant coverage...

Investigation of freeway traffic control strategies’ performance
This paper focus on evaluation of impacts of traffic control strategies on traffic congestion relief. The traffic simulation network is modeled in a traffic microsimulation environment and the calibration with the real world data. As for traffic control strategies, fixed-time ramp metering, speed limit control and integrated control are tested and performances are compared with the actual condition along the...

Dynamics of interstitial calcium in rat myocardial ischemia reperfusion injury in vivo
Intracellular calcium ([Ca++]ic) overload is the key factor for myocardial ischemia reperfusion injury(IR), however there was no report for interstitial Ca++ concentration ([Ca++]ex) dynamics. This research aims to plot the [Ca++]ex dynamics in rat myocardial IR in vivo. A microdialysis system was composed and the time delay of the system, recovery time, was introduced and tested with a fluids switching...

In vitro evaluation of plant extracts against Alternaria brassicae (Berk.) Sacc. causing leaf spot of mustard and Fusarium oxysporum f. sp. lycopersici causing wilt of tomato
Extracts of five plants viz. Azadirachta indica, Lantana camara, Ocimum sanctum, Eucalyptus globulus and Calotropis gigantea were evaluated in vitro by poison food technique (PFT) @ 3, 5, 7 and 9% concentrations against Alternaria brassicae andFusarium oxysporum f. sp. lycopersici causing blight of mustard and wilt of tomato respectively. In vitro study...

Reconditioning effect of oligodendrocyte-like cell transplantation in acute spinal cord injury in rats
To observe the reconditioning effect of oligodendrocyte-like cell transplantation in acute spinal cord injury in rats, bone marrow mesenchymal stem cells were differentiated into oligodendrocyte-like cells induced by cytokines including insulin-like growth factor-1(IGF-1). Rats with acute spinal cord injury were treated with the oligodendrocyte-like cells for 8 weeks by local injection. The therapeutic effect was...

A hybrid approach for text categorization by using x2 statistic, principal component analysis and particle swarm optimization
Today, the number of text documents in digital form is progressively increasing and text categorization becomes the key technology of dealing with organizing text data. A major problem of text categorization is a huge-scale number of features. Most of those are useless, irrelevant or redundant for text categorization. Therefore, these features can decrease the classification performance. In order to eliminate this...
