Guangzhou, characterized by a subtropical climate, exhibits less pronounced seasonal variation, with relatively stable average temperature (T) and relative humidity (RH) during the sampling period (T: 25 °C in summer vs. 12 °C in winter; RH: 73% in summer vs. 76% in winter). In ...
In this paper a two dimensional model for finding the temperature and velocity profile in each section of the pulse tube refrigerator is presented. With the aid of this model the enthalpy flow and entropy generation in the tube section of the pulse tube and coefficient of performance of the ...

Recently, ITER-India, IPR has designed and analysed a cold compressor for maintaining the liquid helium bath in large Tokamak machines. The compressor operated at a temperature of 4.2 K, with a mass flow rate of 0.33 kg/s and pressure ratio of 1.39 [19]. Another example of cold compressor...
Then, the cells were collected, washed twice with pre-cooled PBS (pre-cooled in the refrigerator or ice bath at 4 °C), resuspended in 100 μL PBS, and stained with Annexin V-FITC and PI for 20 min at room temperature (25–26 °C). Positive cells were detected with flow ...

The annual average temperature and annual average rainfall are 18.4 °C and 1049.3 mm. The terrain consists of low–middle mountains, low hills, and hilly plains [19]. In terms of land use types, the study region is characterized by agricultural land, which encompasses 46% of the total ...
The three conductive heat transfer models were applied to a specific composite structure, as shown in Figure 4, by setting different boundary conditions as follows: For the S-to-S model: a fixed temperature of the upper surface as 𝑇highThigh, a fixed temperature of the lower surface as ...
