Background
Nickel (Ni) is the most frequent metal allergen and induces a TH1‐dependent type‐IV allergy. Although Ni2+ is considered to bind to endogenous proteins, it currently remains unclear whether these Ni‐binding proteins are involved in Ni allergy in vivo. We previously reported the adjuvant effects of lipopolysaccharide (LPS) in a Ni allergy mouse model. As LPS induces a number of inflammatory...
Sn-Ag-Cu solder alloys have been widely used as lead-free solders following the enactment of the 2007 RoHS Directive. Recently, the content of Ag has been demanded to decrease in the solders for wave soldering process as the cost of Ag has already become very expensive. On the other hand, it was considered that the mechanical strength of the solder tends to be not enough as the amount of Ag decreases...
In recent years, there has been an increasing interest in sensor networks, in which sensor nodes such as temperature or humidity sensors communicate with each other for environmental monitoring and so on. In sensor networks, it is important to reduce the energy consumption, since sensor nodes have limits in battery. Most researches achieve this by reducing sensor amount of transmitted data. However,...
