Growth in animals is controlled by genetic, environmental, and nutritional factors, including external factors (temperature, pressure, salinity, and light) in the evolution of cold-blooded animals. In this study, the effects of three different light treatments on the growth and survival rates of guppy larvae (Poecilia reticulata) were investigated. The larvae of this species with an average ini...
We present a conjecture, based on computational results, on the area minimizing way to enclose and separate two arbitrary volumes in the flat cubic three-torus T 3. For comparable small volumes, we prove that an area minimizing double bubble in T 3 is the standard double bubble from R 3 .
Abstract Senna fistula (commonly called golden shower tree) is a tropical plant renowned for its established medicinal properties. Additionally, it serves as popular ornamental tree homesteads and roadside plantings. But previous phytochemical studies on the adopted conventional methods of extraction without optimal yield extract. This study investigated phytochemistry S. leaf, stem bark flower...
A recombinant vaccinia virus containing a Drosophila potassium channel (Shaker H4) cDNA was constructed by homologous recombination between wild-type vaccinia virus DNA and a transfer plasmid. The new virus was used to infect four types of mammalian cells in culture. Electrophysiological recording 24-72 hr after infection revealed the expression of voltage-gated transient potassium channels in ...
Experiments were performed in C57BL/6J male mice to determine the effects of acetylcholinesterase (AChE) inhibitor pyridostigmine bromide (PB) and stress on cardiovascular function, structure, and apoptosis. Mice were studied for seven days under the following conditions: Controls (osmotic minipump with saline), PB (10 mg/kg/day, minipumps), shaker stress (45 stressors/day, minipump with saline...
within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
Determination of carbohydrates in soil requires prior extraction and numerous extraction methods were suggested for this purpose. Three methods and five extractants were applied in order to extract carbohydrate fraction in three soil types forest, clayey and saline soils. The extraction methods were: 1) shaken in a plane rotary shaking machine for 16 h 2) heated in steam-bath for 2.5 h and 3) h...
the pea aphid, acyrthosiphon pisum (harris) is one of the most important pests of pea throughout the world.host stage preference under choice and no-choice tests and age-specific functional response of praon volucre (haliday) parasitizing a. pisum were investigated. the experiments were carried out under laboratory conditions at 25 ± 1 °c, 60 ± 5% rh and a photoperiod of 14: 10 h (l: d). functi...
