in this paper, dynamic transient method and conventional degree-hours method (static) have been compared to estimate heating and cooling loads of building’s wall. all main wall surfaces of various orientations, i.e.south, west, east, north, and horizontal are considered in the climate of tehran, iran. in this study, a conventional wall structure, which is comprisedconcrete as main wall material...
Recent climatic trends of two nearby stations in Sydney were examined terms hourly ambient air temperature and wind direction for the time period 1999–2019. A reference was set monthly number cooling (CDH) heating (HDH) degree hours that temperatures exceeded 24 °C (T24) or below 14 (T14), parameters affecting not only energy demands but also quality life. The linked to dominant synoptic condit...

The excessive use of energy in buildings due to increased populations and economic development leads more greenhouse gas emissions, which affect climate change global warming. Changes prevailing outdoor weather conditions significantly the systems through cooling decreased heating. In this paper, 30 years data dry wet bulb temperatures (1990–2020) with a time interval 3 h were considered order ...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
