The effect of body warming and cooling on the heart and breathing rates has been studied in the agamid lizard Uromastyx microlipes. Electrocardiograph (ECG) of Uromastyx microlipes consists of P, QRS, and T components similar to those in mammals. Heart rate increases with body temperature. During warming the heart rate ranged from 7-134 beat/min, while during cooling ranged from 2-73 beat/min. ...

Darlingtonia californica is a carnivorous plant with a patchy distribution in coastal Oregon and northern California, USA. A number of arthropod species inhabit and exploit its fluid-filled pitchers; among these is a hististomatid mite, Sarraceniopus darlingtonia, an obligate inhabitant that feeds on the rich microbial growth associated with decomposing arthropods captured by the pitcher. Males...

This paper deals with the sanitary conditions of the water and bottom sediments in the Lower Vistula river, between Wyszogród and Toruń. The contamination extent of the water and bottom sediments by easily decomposable organic matter and substances of faecal origin have been indirectly estimated by determining the total number of heterotrophic bacteria (TVC 20oC) and the occurrence of the faeca...

The kinetic characteristics of soil urease have attracted great attention, but little information was available on its kinetic and thermodynamic behaviors as affected by urease inhibitors and temperature. With black soil (Pachic Udic Mollisol) in Heilongjiang Province of Northeast China as a test soil, an incubation test was conducted to investigate the effect of urease inhibitors (hydroquinone...

The importance acquired by the strategy of anticipating rubella revacunation needs no emphasis1. Recommendations by experts committees and actualization of the prevailing childhood immunization schedules are unanimous when it comes to including the above-mentioned strategy2. In this context, seroepidemiologic survey studies allow the assesment of humoral immunologic response against viral struc...

The effects of various Abiotic factors, including concentrations of silicate and iron, temperature, light intensity and salinity of media on two purebred red tide diatoms, Phaeodactylum tricornutum and Thalassiosira weissflogii were investigated through single and full factorial experiments. The single-factor experiments showed diatom Phaeodactylum tricornutum had the fastest growth rate with i...

 The equilibrium moisture content of malting barley grains (cv. Scarlett) was determined by gravimetric-static method in the range 20-50°C using saturated salt solutions (LiCl, MgCl2.6H2O, K2CO3, NaBr, NaNO2, KI, NaNO3, NaCl, (NH4)2SO4) to provide water activities for each temperature between 0.11 and 0.813. Desorption isotherms were obtained at 20, 30, 40, and 50°C. All the sorption curves w...

This study was conducted to detect for the first time the occurrence of phytoplasma in symptomatic faba bean plants in Saudi Arabia. Faba bean is one of the most widely grown protein-producing food legumes. Ten leaf and stem samples showing symptoms of phyllody and stunting were collected from plants grown in Agricultural Research Station field Riyadh region, Saudi Arabia during December, 2011....

Direct expansion (DX) refrigeration technology is almost exclusively used in multi-temperature transport refrigeration systems. Multi-temperature systems use up to three evaporators, requiring large refrigerant charges and system pressure control to operate over a wide range of set-point conditions. Despite incremental design improvements over the past decade, environmental and control issues c...

The subject of this work was fumonisin B1 (FB1) and moniliformin (MON) biosynthesis by three isolates of Fusarium oxysporum and three isolates of F. proliferatum of asparagus spears origin. The cultures of fungi were grown on rice and asparagus media for 3 weeks at 20oC. Experiment was carried out in 3 replicates. FB1 and MON occurrence was evaluated with high-performance liquid chromatography ...
