In this paper, the thermal convection field and its resonance phenomena in a square cavity with sinusoidal heat-flux vibration were numerically investigated. As the angular velocity ω is changed, the thermal convection field at Pr = 0.71, Ra = 10 6 is found to be classified into 5 regions. In particular, the field has the local maximum relative amplitude of midplane Nusselt's number at ω c = 350, which corresponds to the angular velocity of internal gravity wave ω r estimated by a theoretical equation proposed by Thorpe. This shows that the local enhancement is induced by internal gravity wave resonance. Such correspondence is observed for Ra ≥ 10 5 , Ra ≥ 10 6 for Pr = 0.71, 7.1, respectively. For these ranges of Ra we propose a correlation equation, a function of Pr and Gr only, to estimate the resonant angular velocity.
In this paper the thermal convection field and its resonance phenomena in a rectangular cavity with heat-flux vibration are numerically examined and the results are compared with those of a square cavity. As in the case of α = 1, the critical angular velocity at which the relative amplitude of the midplane Nusselt number α m has a local maximum agrees very well with the resonance angular velocity of the internal gravity wave ω r , estimated by the theoretical equation proposed by Thorpe, even when the aspect ratio is α = 5 and the Prandtl number is Pr = 0.71 for a range of the Rayleigh number Ra. However, α m has two local maxima for a larger Ra, which is peculiar to the case of larger α. The time variation of sub-components of the fluctuating component of the midplane Nusselt number shows that the phase at the maximum value of α m agrees well with that of the sub-component of velocity for the first resonance angular velocity ω r . For the other angular velocity ω r2 , the phase of α m agrees with that of the sub-component of temperature. Moreover, we found that the boundary angular velocity ω 0 between the first two of the five ω regions, which classify the thermal convection fields against ω, can be expressed by a function of α, Ra, and Pr and that α m is independent of α and Ra for a relatively wide range of ω/ω 0 .
Chemoradiation therapy (CRT) is becoming the standard treatment for anal canal squamous cell carcinoma (AC-SCC). In this study, we examined the treatment results of 7 cases of ACSCC treated at our hospital. TNM classification was 1 case, 1 case, 5 cases and 0 case of Stage Ⅰ, Ⅱ, Ⅲ and Ⅳ, respectively. CRT was performed in all cases. Two courses of chemotherapy with 5-FU and mitomycin C (cisplatin for one patient) were performed. Radiation therapy was performed in the pelvis and both inguinal lymph node areas. As a result, CR was obtained in all cases and all cases survived without recurrence. As Grade 3 or higher adverse events, diarrhea, hematologic adverse events and radiation dermatitis occurred.Grade 2 radiation rectalitis and radiation cystitis were observed as late adverse effects. We also searched case reports of ACSCC treated with CRT in Japan and obtained relatively good outcomes. CRT is considered to be a curative treatment method in Japan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
