Goldfish were trained to press a lever. This response was followed by the delivery of a pellet of food. The fish were then allowed continuous access to the lever under controlled conditions, and their food intake was measured. Goldfish distribute their feeding responses fairly evenly over time, within the limits of the lighting cycle. Some fish eat mainly at night, some during the day, and othe...

Captopril oral suspensions were prepared by compounding Captopril powder with Humco’s Oral Products’ (Flavor Sweet : Flavor Plus 1:1; and Flavor Sweet-Sugar Free : Flavor Plus 1:1), at two concentrations: 0.8 mg/mL and 4 mg/mL. These bracket concentrations of all Captopril formulations were stored in low-actinic plastic prescription bottles at controlled room temperature (25 °C and 60% RH) and ...

Since the appearance of the first paper of Gamer and Allard on photoperiodism {5Y an extensive hterature covering various phases of the subject has developed. The accumulated data as a whole are sufficiently comprehensive and consistent to remove any doubt as to the practical importance of length of day as a factor in plant growth and development. However, only in comparatively few instances ha...

The experiment was conducted under a controlled environment to study the effects of different temperature regimes (15/10°C,20/15°C, and 25/20°C day/night) and sowing depths (0, 2, 4, and 6 cm) on the seedling emergence and early growth (height gain) of wheat (cv. Marvdasht) and wild barley (Hordeum spontaneum).The cumulative emergence and plant height gain over time were modeled with the use of...

Soil temperature influences crop growth and quality under field and greenhouse conditions; however, precise investigation using controlled cultivation systems is largely lacking. We investigated effects of root-zone temperatures on growth and components of hydroponically grown red leaf lettuce (Lactuca sativa L. cv. Red Wave) under a controlled cultivation system at 20 ̊C. Compared with ambient ...

background: edifenphos, a kind of organophosphate toxins, is used as agricultural fungicides in rice fields. this study was aimed to investigate the effect of temperature on lethal concentration of exposure to edifenphos on rutilus frisii kutum (caspian kutum). methods: the experiment was carried out in static condition and based on instructions of oecd within 10 d under controlled water physic...
