Electric vehicle[1] endurance has always been a major concern for car buyers. Based on the six conventional electric vehicles selected from market, driving range of chassis dynamometer with environment warehouse is first carried out under CLTC-P condition normal temperature environment, and compared vehicle meter-display range. After testing speed 100 km/h range, high-speed at obtained, then dr...

This study was conducted to determine the effects of increased water temperatures on the development of Aedes aegypti immatures under laboratory conditions in Trinidad, West Indies using temperature regulated water baths to cover a range of temperatures from 24-25°C to 34-35°C at a relative humidity of 80%. Two experiments were designed: (1) at constant temperature regimens and (2) under diurna...

In tropical areas, where vector insects populations are particularly numerous, temperature usually range between 25 degrees C and 35 degrees C. Considering the importance of such temperature variation in determining mosquitoes population dynamics, in this work the developmental, eclosion and survival rates of the immature stages of Aedes albopictus (Skuse) were compared under constant 25, 30 an...

Many environmental parameters modulate the amount of the RpoS sigma factor in Escherichia coli. Temperature control of RpoS depends on the untranslated RNA DsrA. DsrA activates RpoS translation by pairing with the leader of the mRNA. We find that temperature affects both the rate of transcription initiation of the dsrA gene and the stability of DsrA RNA. Both are increased at low temperature (2...

The influence of temperature on the development and embryonation of Ascaris suum eggs was studied using coarse sand medium in an environmental chamber with 50% humidity. The time required for development and embryonation of eggs was examined under 3 different temperature conditions, 5°C, 25°C, and 35°C. A. suum eggs did not develop over 1 month at the temperature of 5°C. However, other temperat...

The effects of methyl bromide (MB) concentration (16, 32, 48, or 64 g/m), fumigation temperature (15, 20, 25, or 30 C), and fumigation time interactions on the survival of Mediterranean fruit ßy,Ceratitis capitata (Wiedemann), and oriental fruit ßy, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), eggs and Þrst and third instars were recorded. Increasing the fumigation temperature from 15 t...

Some new nitrogen bridge-head pyrido[1,2-b][1,2,4]triazepines incorporating 6methylchromone moiety have been synthesized from the reaction of 1,6-diamino-4-(6methyl-4-oxo-4H-chromen-3-yl)-2-oxo-1,2-dihydropyridine-3,5-dicarbonitrile (4) with some α,γ-bifunctional electrophiles including 2-cyano-3,3-bis(methylthio)acrylonitrile, 2cyano-3,3-bis(methylthio)prop-2-enamide, 5-chloro-3-methyl-1-pheny...
