In 2010 an estimated 109 million infants were immunized against DTP, which serves as a good proxy for vaccinations in general. At the same time, however, approximately 19.3 million infants worldwide were not reached by routine DTP immunization services. Immunization rates tend to be ... 詳細を見る
CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... 詳細を見る
Power-to-gas is an important area of research for reducing greenhouse gases and seasonal energy storage. Methane, with a Lower Heating Value of 50 MJ/kg, is already a commonly used gas, and its synthesis using green hydrogen production (electrolysis of renewable energy) is a remarkable ... 詳細を見る
Batteries are considered a key technology for the transition to climate neutrality. There is an urgent need to improve the resource efficiency of existing technologies while transitioning to next-generation battery systems. A mechanistic battery model is a powerful tool to accelerate ... 詳細を見る
摘 要：稻谷籽粒在储藏过程中温度和水分随着仓外大气环境影响而改变，并导致其发生稻米颜色有白色变为黄色（黄变），并形成黄粒米。该研究基于COMSOL模拟的方法，模拟分析了浅圆仓仓储稻谷籽粒自然密闭储藏期间稻谷黄变规律。研究发现，当稻谷全年自然密闭储藏时，由于稻谷籽粒的呼吸放热，粮堆内部大部分区域温度都非常高，超过了35℃；同时，在粮堆内部形成空气的自然对流，引起粮堆内部水分向上部粮面迁移，并家具该区域的稻谷籽粒黄变的速度。另外，还对密闭储藏时不同高径比的浅圆仓南内部稻谷籽粒黄变规律进行了探究。研究结果为粮食仓储企业安全储粮提供参考和理论依据。 关键词：浅圆仓；自然储藏 ... 詳細を見る
One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... 詳細を見る
Hydrogen refueling in a metal hydride based automotive hydrogen storage system is an exothermic reaction and hence an efficient heat exchanger is required to remove the heat for fast refueling. In this paper a helical coil heat exchanger embedded in a sodium alanate bed is modeled using ... 詳細を見る
Axial-flux permanent-magnet motors are an important technology in many technical applications, being an alternative to radial-flux motors. Axial-flux motors come up with many advantages in comparison to radial-flux motors such as high-power density, higher torque to weight ratio etc. ... 詳細を見る
Lithium-ion batteries are leading the electrification transition, particularly within the transport sector. However, numerous challenges still remain, with fast charging emerging as a major concern. To speed up research, physics-based models are frequently employed alongside experimental ... 詳細を見る
