  • This study was conducted to determine the effects of soybean cultivation on yield and other characters in a newly reclaimed soil. Four factois - (1) plant density (2) compost application (3) innoculation of nodule bacteria (Rhizobium japonicum) combined with lime application (4) NPK application-were examined in a 24 factorial experiments arranged in randomized complete block design with 4 replicates. Kangio variety was used and the results obtained are summarized as follows; (1) Dense plant population, Application of Compost and application of fertilizer (NPK) gave the yields 1.7, 1.4 and 2.1 times the check respectively. The Combinations of, dense $population{\times}compost$, dense $compost{\times}fertilizer$ (NPK), $population{\times}compost{\times}fertilizer$ (NPK), and dense $population{\times}compost{\times}nodule$ bacteria with $lime{\times}fertilizer$ (NPK) increased the yields by 2.0, 3.0, 2.6 and 5.4 times than the check respectively. But little effect on yield was noted in the treatment inoculated with nodule bacteria with lime. (2) In the case of higher yield, the increased weight of 100 seeds was found. (3) A markedly increased PH was observed in all of the plots under study after the completion of experiment. (4) The compost treatment and the ferttilizer (NPK) treatment greatly increased the organic matter, total nitrogen and the available phosphorus in the soil. (5) The variation in the grain yield appeared to have a close correlation with the content of available $P_2O_5$ in the soil.

  • Dans les arts modernes, nous ressentons souvent un $probl\`{e}me$ $disloqu\'{e}par$ rapport aux humains. Ceci ne viendrait-il pas $peut-\^{e}tre$ do notre $pens\'{e}e$ dans l' $\'{e}change$ culturelle entre le monde et nous qui s' appuie trop une $temporalit\'{e}$ et logique? Cette $the\`{s}e$ approche ce $probl\`{e}me$ $\`{a}$ travers one perception anthropologique do monde, en $\'{e}tudiant$ les arts tridimensionnels avec ses $\'{e}schelles$ qui deviennes plus on plus agrandis. Maurice Merleau-Ponty, dans son livre 'la $ph\'{e}nom\'{e}nologie$ de la perception', bien $r\'{e}sumait$ une $intersubjectivit\'{e}$ entre l' espace et nous. Selon lui, l' homme prend conscience do la forme des objets avec son environnement parce quil est un corps on interaction avec eux. Donc nous $r\'{e}f\'{e}rons$ ce livre pour notre set. Et on essayera ici d' $\'{e}tudier$ le travail do Constantin Brancusi, de Alberto Giacometti, do Richard Serra et do quelques d' autres travaux d' artistes L' oeuvre do Brancusi 'la Colonne sans fin', la taille plus de 29 m, produit one impression sur le spectateur relativement $\grave{a}$ la forme continue et $r\'{e}p\'{e}t\'{e}e$ $\`{a}$ linfini de $mani\'{e}re$ unifome. La pratique de Giacometti qui tenait compte do son envergure et de la longueur do son corps ainsi que do distance et de la mesure do sos bras, Il $d\'{e}formait$ aussi les silhouettes et transformait les objects en les $\'{e}tirant$ dans la perspective. Rosalind Krauss parler $\`{a}$ loeuvre do Serra, dans son livre 'l' originalit de lavant-garde et sutres mythes modernistes' (pp. 319-333), le spectateur est toujours on mouvement on liaison entre l' horizon do corps et celui do monde. Cette $transitivit\'{e}$ abstraite $r\'{e}ciproque$ entre le regardeur et le $regard\'{e}$, qui est comme le sujet de nombreuses oeuvres do Serra. Cependant le Maximalisme est $\`{a}$ l' origine Minimalisme qui s' $\'{e}tend$ dans ses efforts $th\'{e}oriques$ jusqu' au l' espace architecturale. Ces sculptures do grandes dimensions so situent autour de $b\^{a}timent$ ou dans lespace environnementale, comme ils sent l' architecture et le paysage. On suppose ici, leurs concepts de l' espace $\'{e}largit$ $\`{a}$ celui d' architecture. La sculpture et l' architecture $r\'{e}ciproque$ l' espace tridimensionnel entre eux, mais selon l' argument do Herbert Read pour la distinction de ces deux arts originaux sont, deux saisies de l' espace, ici englobant, $l\`{a}$ $englob\'{e}$. On $\'{e}tudie$ dans co set de concept de l' espace et de l' $\'{e}chelle$ d' objet par rapport au corps humain.

  • In this study, the design of UV-free reflecting reactor was studied to enhance the cutting fluid life for cutting machine. And also, the stability of cutting fluid with addition of biocide in cutting fluid and without biocide was compared with respect to the cutting fluid concentration, pH changes and microorganisms. Low number of microorganism was observed in the cutting fluid after UV-free reflecting treatment as compare to the cutting fluid which was added biocide and just cutting fluid alone. PH of the cutting fluid after UV-free reflecting treatment was about 9$\sim$8.5 while others were observed considerably low. The oil contents of cutting fluid which was added biocied and pure cutting fluid were almost degraded with the passage of time. However, in case of UV-free reflecting reactor, 4$\sim$3.5 Brix oil contents were observed in the cutting fluid.
