Keeping a healthy and balanced diet has long been a critical issue for a person wanting to stay fit and energetic in her/his daily life. We can always turn to a dietitian (or a nutritionist) for professional diet suggestions if necessary. However, we cannot have a dietitian staying with us all the time, which renders daily nutrition control very challenging. Therefore, it is desirable for each ...

There is a niche for a sub-Kelvin cryogenic refrigeration unit that is simple, efficient, and does not require gravity. The superfluid Stirling refrigerator was developed in response to this demand. The refrigerator has cooled to 168 mK while exhausting heat at 383 mK, demonstrating the potential to cool to temperatures well below that attainable with a continuous 3He evaporation refrigerator. ...

As refrigeration has become one of the basic needs people of this era. The permanent demand of refrigerator is continuously increases in India and also in the whole world. The energy consumption in the refrigeration is also increases. Approximately it contribute around 13% energy consume in this sector. In the kitchen appliances, only the refrigerator consumes power continuously throughout a da...

The water-cooled heat exchanger is one of the key components in a pulse tube refrigerator. Its heat exchange effectiveness directly influences the cooling performance of the refrigerator. However, effective heat exchange does not always result in a good performance, because excessively reinforced heat exchange can lead to additional flow loss. In this paper, seven different water-cooled heat ex...

Domestic refrigerator-freezers are very widely used for food preservation. There is still growing demand especially in developing countries like India. The growth rate in India for domestic refrigerators is about 15 percent. A large inventory of such appliances exists in India. In recent years, an emphasis is paid to improve the energy efficiency of domestic refrigerator-freezers have to reduce...

Quantum technology promises revolutionizing applications in information processing, communications, sensing and modelling. However, efficient on-demand cooling of the functional quantum degrees of freedom remains challenging in many solid-state implementations, such as superconducting circuits. Here we demonstrate direct cooling of a superconducting resonator mode using voltage-controllable ele...

Please cite this article in press as: Burton JC doi:10.1016/j.cryogenics.2011.03.001 We have designed and constructed a continuously operating He cryostat with windows for laser ablation and spectroscopy. A two-stage pulse-tube refrigerator cools two platforms to base temperatures of approximately 40 K and 4 K respectively. The platforms are equipped with heat exchangers that cool separate stre...

The objective of this study was to test the effect of four different diluents on the motility of goat semen stored at room and refrigerator temperatures. To achieve this objective, four West African dwarf bucks aged 10-12 months were ejaculated weekly for five weeks using the electro-ejaculator method. The ejaculated semen were extended using four diluents namely sodium citrate (T1), sodium bic...
