Being ectothermic, fish body temperature generally depends on ambient water temperature. Thus, ambient temperature might affect various sensory systems, including hearing, as a result of metabolic and physiological processes. However, the maintenance of sensory functions in a changing environment may be crucial for an animal's survival. Many fish species rely on hearing for acoustic orientation...

Degree-days are important parameters for developing predictive models of mosquito populations. Conventional methods of estimation of degree-days are typically applied to observations under constant temperatures in the laboratory. These methods are difficult to apply in the field where temperatures fluctuate. For estimating degree-days of larval developments of mosquitoes in the field, we applie...

Microclimate in open space affected by the urban layout and spatial forms plays an important role in the outdoor comfort, thus the outdoor activities based on the comfort sensation will directly affected by the spatial forms. An outstanding open space should satisfy different requirements of outdoor activities and create relatively comfortable place.Most studies have been conducted on the...

Acetic acid was separated from a dilute mixture using a commercial polyvinyl alcohol (PVA) membrane.  Intrinsic separation characteristics of the membrane were studied as a function of temperature.  The degree of membrane swelling decreased marginally with increase in feed temperature. At 25oC the maximum degree of swelling was found out to be 46.3%, which reduced to 39.5%...

The 360-degree camera is a relatively new technology that might become an effective tool for the development of students and teachers overall educational improvement. As “normal” video provides maximum 130-degree perspective, it could not offer complex capture education. This paper presents way to use during two different modes trainee teachers’ fieldwork proposes how evaluate this form educati...

In this work, nonlocal elasticity theory is applied to analyze nonlinear free vibrations of slightly curved multi-walled carbon nanotubes resting on nonlinear Winkler and Pasternak foundations in a thermal and magnetic environment. With the aid of Galerkin decomposition method, the systems of nonlinear partial differential equations are transformed into systems of nonlinear ordinary differentia...

In this research samples of PVOH were synthesized at various reaction conditions (temperature, time, and amount of catalyst). First at 25˚C and 45˚C and constant catalyst weight samples of PVOH were prepared with different degree of hydrolysis at various times. For investigation of the effects of temperature, at times 20 and 40 min and constant weight of catalyst PVOH was prepared at various te...

In the present study, temporal behavior of entanglement between photonic binomial distributions and a two-level atom in a leaky cavity, in equilibrium with the environment at a temperature T, is studied. In this regard, the master equation is solved in the secular approximation for the density matrix, when the initial photonic distribution is binomial, while the atomic states obey the Boltzmann...
