Development of a thermal sensor for probing small volumes [PDF]
, 2012 This thesis presents the design, fabrication and characterisation of a thermal micro-sensor capable of operating on small scale samples. It was initially characterised by measuring the thermal conductivity of 100 μl liquid droplets and thin materials ...

Effects of contact resistance on thermal-conductivity of composite media with a periodic structure
, 1992 The thermal conductivity of periodic composite media with spherical or cylindrical inclusions embedded in a homogeneous matrix is discussed. Using Green functions, we show that the Rayleigh identity can be generalized to deal with thermal properties ot ...

Experimental Investigation of Forced Convection Heat Transfer in Open Cell Copper Fins
مجلة النهرين للعلوم الهندسية, 2017 Recently, major part of convection heat transfer researches focus on increasing fins efficiency by increasing thermal performance for the same fin volume. Metal foam is a promising way to achieve this aim.

Building Envelopes with Controlled Thermal Resistance
Traditionally low energy buildings are supposed to have maximally big thermal resistance of building envelope. In reality big thermal resistance is justified only in coldest winter days in countries with cold climate or in hot summer days with intensive ...

Role of carbon nanotube on the interfacial thermal resistance: A molecular dynamics approach
, 2017 Very high thermal conductivity of carbon nanotube (CNT) makes it an obvious choice in electronic cooling applications. But at the nanoscale, these CNTs face a limitation due to the interfacial thermal resistance commonly known as Kapitza resistance ...

Factors affecting the rotational use of insecticides for the management of resistance in mosquitoes [PDF]
The rotation of the use of chemically unrelated insecticides has been advocated to delay the build up of resistance. To examine this concept in the laboratory, Anopheles albimanus and Culex guinquefasciatus were subjected
