Fundamental Study of Magnetic Separation Method for Radioactive Contaminant

Since the accident that happened in The Fukushima Daiichi Nuclear Power Station, a scattered radiological decontamination and decommissioning technology are attracting a lot of attention. The removal of radioactive crud in the nuclear power plant will become one of the more important elemental technologies of the decommissioning from now on. However, the effective technique to remove the crud which is applicable at high-temperature area around the nuclear power plant does not exist. Therefore, we focused on the magnetic property of the target cruds which are paramagnetic substance and high gradient magnetic separation (HGMS) was proposed as a nuclear power plant crud removal method. In this study, we tested the magnetic separation of crud sample model in room temperature for the practical use of the HGMS device and a possibility of the application of our method was indicated.departmental bulletin pape

DataSheet_1_Reaction of SARS-CoV-2 antibodies with other pathogens, vaccines, and food antigens.docx

It has been shown that SARS-CoV-2 shares homology and cross-reacts with vaccines, other viruses, common bacteria and many human tissues. We were inspired by these findings, firstly, to investigate the reaction of SARS-CoV-2 monoclonal antibody with different pathogens and vaccines, particularly DTaP. Additionally, since our earlier studies have shown immune reactivity by antibodies made against pathogens and autoantigens towards different food antigens, we also studied cross-reaction between SARS-CoV-2 and common foods. For this, we reacted monoclonal and polyclonal antibodies against SARS-CoV-2 spike protein and nucleoprotein with 15 different bacterial and viral antigens and 2 different vaccines, BCG and DTaP, as well as with 180 different food peptides and proteins. The strongest reaction by SARS-CoV-2 antibodies were with DTaP vaccine antigen, E. faecalis, roasted almond, broccoli, soy, cashew, α+β casein and milk, pork, rice endochitinase, pineapple bromelain, and lentil lectin. Because the immune system tends to form immune responses towards the original version of an antigen that it has encountered, this cross-reactivity may have its advantages with regards to immunity against SARS-CoV-2, where the SARS-CoV-2 virus may elicit a “remembered” immune response because of its structural similarity to a pathogen or food antigen to which the immune system was previously exposed. Our findings indicate that cross-reactivity elicited by DTaP vaccines in combination with common herpesviruses, bacteria that are part of our normal flora such as E. faecalis, and foods that we consume on a daily basis should be investigated for possible cross-protection against COVID-19. Additional experiments would be needed to clarify whether or not this cross-protection is due to cross-reactive antibodies or long-term memory T and B cells in the blood.</p

振動インテンシティ計測法の基礎的検討

This paper describes methods for measurement of vibration intensity. The object is to make differences clear in effectuality of the methods to the search of exciting and absorbing points on homogeneous beams or flat plates. The intensity measurements studied are the finite difference method,the finite difference method neglecting the cross terms of the two directions in the plane and the cross-spectrum method, in which the second and third methods are compared with the first basic method. The vibration intensity maps evaluated by these methods based on computational frequency response simulations show that(1) the cross-spectrum method which holds on the assumption of complete free field is effectual for the survey of paths of vibration energy flow in the rough,but it is not effectual for the search of the exciting and absorbing points,but(2)the finite difference method neglecting the cross terms is effectual for the survey the of paths and the search of the points.journal articl
