ソウセツ ショウニ BIPHENOTYPIC LEUKEMIA ノ ブンルイ ノ ココロミ

Seven hundred and forty-five newly diagnosed patients with acute leukemias between 1978 and 1990 were classified on the basis of immunological phenotype. The incidence of subclassification of acute leukemias in this study was as follows: 522 patients with ALL (70%), 139 patiens with ANLL (18%), 29 patients with biphenotypic leukemia, 8 patients with Ph1-positive acute leukemia, and 46 patients with infantile leukemia. ALLs were classified into common ALL (77%), T-ALL (15%), B-ALL (4%), and unclassified ALL (3%). Biphenotypic leukemias were categorized into 4 groups as follows; 1) common ALL with positive myelomonocytic antigen(s) (N=11), 2) unclassified ALL with positive myelomonocytic antigen(s) (N=5), 3) ANLL with positive B-lymphoid antigen(s) (N=4) and 4) acute leukemia with positive T-lymphoid and myeloid antigen(s). Among these 4 groups of biphenotypic leukemia, groups 2 and 4 disclosed a poor prognosis as was reported in infantile leukemia and Ph1-positive acute leukemia. Many questions regarding the biological and clinical aspects of biphenotypic leukemias stiil remain to be solved, but the precise and detailed sutailed subclassifications of acute leukemias will establish an appropriete strategy of therapy.journal articl

太陽熱利用による穀物の人工乾燥(II) : ビニールハウス利用乾燥設備の所要規模について

application/pdfAssuming that solar dryer system using the green house as a solar collector is incorporated into the mechanized rice cropping operation system most popular in our country, studies were made to determine the facility scale of dryer system required for performing grain drying smoothly. The salient points obtained are as follows: 1)First, study was made concerning how much holding capacity is required for the grain dryer utilizing solar energy. Formula (2-2) was proposed with which the optimum holding capacity of the dryer can be calculated on the basis of daily harvesting amount of grain by combine. Next, required drying quantity per day was determined from the standpoint of full use of the drying the proper harvesting period. Then formula (2-5) was derived as a calculation formula to obtain that holding capacity of a dryer which is calculated on the basis of above required drying quantity. 2) By picking up factors having effects on the area of a solar collector house, all of those characteristics are made clear. From these date, formula (2-11 & 2-12) were proposed to calculate adequate area of the collector house. House area (㎡)/Grain (100㎏) and Air volume (m³/sec)/House area (㎡), required for calculation of adequate house area, in relation to the collector efficiency of the house, air temperature rise within the house and drying rate, were represented graphically based on the results of experiments conducted up to the present. Numerical values required for calculation of adequate house area can be read there-from.departmental bulletin pape

サブバンド信号処理に基づくアダプティブアレーアンテナの開発

時空間信号処理を行うアダプティブアレーは、将来の高速移動体通信システムにおいて有効なマルチパス対策となるものと期待される反面、適応的に制御される重み係数の数が非常に多くなることから、ハードウェアへの実装にあたってその膨大な計算負荷が問題となる。このため、計算量の削減が実用化への鍵となっているということができる。本論文では、計算量の大幅な削減が可能なサブバンド信号処理を行うアダプティブアレーを、市販のDSP(Digital Signal Processor)を用いてハードウェアに実装した。そこでまず、必要な信号処理の各部に必要なDSPの数を示すことにより、ハードウェア規模を明らかにした。次に、電波暗室内において２波の簡単なマルチパス環境を構成し、その下で基本性能の実証実験を行って、理論値とほぼ一致する性能が得られることを確認した。journal articl
