(1(1):13-19)An Observation on the Flower Morphology and Flower Setting Habit of European Lemon
No full text檸檬果實以其果皮及果肉中，含有特異之香味，故今日各地均以此為最名貴飲料之一，香料工業中又以其花朶，果實，及葉等部含油特多，供為精製優良香料之用，故檸檬之用途，遂日見廣大。
檸檬生長之習性，以較高溫之地為適宜，原產於印度，今日之主產地為伊大利之Sicily島及美國加洲之Corona地方，臺灣以新竹栽培頗多，本所士林園藝試驗分所及國立臺灣大學園藝場栽培之成績亦甚佳，查檸檬盛產地Sicily島之年溫度為19℃，相關濕度為60%，年雨量為1,000mm.臺灣新竹之年溫為22℃，濕度80%，年雨量1,690mm. 等氣候環境觀之均與福州，漳州，潮州及廣州等地相若，若能推廣種植，亦可獲得優良之成績，藉以廣供優良飲料及香料之用，裨益當非鮮淺。
本篇乃檸檬花朶形態及枝條著花並結果習性之觀察，以供柑桔類研究之參考。1.This observation was conducted in the Spring, 1949. The tree and flower used for this observation was European Lemon (Citrus limon, Burm), which are grown in the Siu-Lin Horticultural Branch of Taiwan Agricultural Research Institude and the Horticultural Experiment Station of Taiwan University.
2.There are three kinds of flowers, namely, perfect, staminate and reduced small flowers in the trees of European lemon. The staminate and reduced small flowers are about one half to two third of all the flowers.
3.The staminate flowers are smaller, lighter, and its petals are thiner, and the number of the stamens is fewer than that of the perfect flowers. The staminate flowers increased at the later stage of the blooming.
4.There are much of the reduced small flowers in the weak branches.
5.Most of the flowers are blossomed in the Spring, and setting on the autumn branches. And most of the fruits are setted on the top of the bearing shoots and bearers.
6.It is significient difference of simple Correlation between the number of the flowers and the main characters of the branches. As in partial correlation 1st, it is significient difference between the number of the flowers and the size of the branches, and not significient if excluded the factor of the length of the branches. The difference is also significient between the number of the flowers and the number of the branch nodes, as under the influence of the factor of the length of the branches.
As in partial correlation of 2nd, it is no significient difference between the numder of the flowers and the characters of the branches.
The numher of the flowers and the characters of the branches is significient in multip’e Correlation.
7.The flower of European Lemon has the habit of parthenocarpy

No full textPhotograph of the historic tree at Mission Carmel (San Carlos Borromeo de Carmelo) in Monterey, ca.1888. The tree stands at center, growing from the slope of a hill that feeds into the dry ravine at left. In the background left, the gaurd rail of a bridge can be seen.; "Viscaino hung bell on this tree and held mass in 1602 and Father Juniper Serra utilized it for the same purpose June 3, 1770 when he first landed to establish a mission for Saint Charles. [Also the boat was tied here.] The tree fell early in 1900 and the trunk was removed to the garden at rear of San Carlos Mission in Monterey. Photo made by a Mr. Adams [a photographer of Monterey about 1890] abt. 1880 and [negative] purchased from him about 1895 by C.C. Pierce". -- Unknown author
Sterkte en vervorming van waterbouwasfaltbeton (I)
No full text-Bereiding van proefstukken waterbouwasfaltbeton op lab-schaal met een constante kwaliteit blijkt tot de mogelijkheden te behoren. Bij 7% bitumen kan de verdichting vermoedelijk lichter zijn dan de standaardmethode voor wegenbouwmengsels om een holle ruimteniveau van circa 4% te bereiken. Het is de vraag of dit ook bij 6, 5% bitumen het geval kan zijn. -Het kruip- en rekonderzoek geeft als duidelijke indicatie, dat de vervorming en S-modulus mede afhankelijk zijn van het type normaalspanning. Intensiever onderzoek, mede met het oog op de spreiding in resultaten, zal moeten uitwijzen, hoe die afhankelijkheid precies is. - Bij de bezwijkproeven blijkt de sterkte mede afhankelijk van het type normaalspanning. Dit is veel minder het geval bij de resulterende vervormingen. Als gevolg van beide is toch de S-modulus sterk afhankelijk van het feit, of deze met druk- of trekspanningen is bepaald. - Bij alle proeven blijkt de grote invloed van de temperatuur en vervormingssnelheid op het vervormingsgedrag en de sterkte. -Voor een betere interpretatie van de splijtproeven is het noodzakelijk de horizontale vervormingen te meten, zodat de S-modulus kan worden vastgesteld. - Het totaal aan stijfheidsmoduli geeft een band als "mastercurve". De met drukspanningen bepaalde waarden liggen in het algemeen op een hoger niveau dan de met trekspanningen bepaalde waarden. -Voor de bepaling van het hogere stijfheidsniveau moeten dynamische onderzoeksmethoden worden gehanteerd.TAW A4 Asfalttoepassinge
Production-location decision and free entry oligopoly: A correction
No full textThis paper shows that there is no interior solution in Mai–Hwang's 1992 oligopolistic location model with free entry when the production function exhibits constant or decreasing returns to scale. The comparative static results of the impact of a demand change on the location decision only apply to the case where the production function exhibits increasing returns to scale. It re-examines the impact of a demand change on the location decision of an oligopolistic firm and corrects the propositions derived by [C.C. Mai, H. Hwang, Production-location decision and free entry oligopoly, Journal of Urban Economics 33 (1992) 252–271. Reprinted in: M.L. Greenhut, G. Norman (Eds.), The Economics of Location, vol. I: Location Theory, Edward Elgar, Aldershot, 1995].SSC
Measurements of psi(3686) -> k-lambda(Xi)over-bar(+) + c.c. and psi(3686) -> gamma k-lambda(xi)over-bar(+) + c.c.
No full textÇetin, Serkant Ali (Dogus Author)Using a sample of 1.06 x 10(8) psi(3686) events produced in e(+)e(-) collisions at root s = 3.686 GeV and collected with the BESIII detector at the BEPCII collider, we present studies of the decays psi(3686) -> K-Lambda(Xi) over bar (+) + c.c. and psi(3686) -> gamma K-Lambda(Xi) over bar (+) + c.c. We observe two hyperons, Xi(1690)(-) and Xi(1820)(-), in the K-Lambda invariant mass distribution in the decay psi(3686) -> K-Lambda(Xi) over bar (+) + c.c. with significances of 4.9 sigma and 6.2 sigma, respectively. The branching fractions of psi(3686) -> K-Lambda(Xi) over bar (+) + c.c., psi(3686) -> K-Sigma(0)(Xi) over bar (+) + c.c, psi(3686) -> gamma chi cJ -> gamma K-Lambda(Xi) over bar (+) + c.c (J = 0, 1, 2), and psi(3686) -> Xi(1690/1820)(-)(Xi) over bar (+) + c.c with sub-sequent decay Xi(1690/1820)(-) -> K-Lambda are measured for the first time

No full text於網室內觀察稻各生育期對菌核性病害之感病狀況，均於稱生育後期之感病程度為高。但在溫室內稻之生育狀態或發病狀態等均與自然界有異，一般觀之，稻生育時期的變遷與罹病性很明顯，即稱生育初期之感病較多，但其後之病勢進展至上位葉鞘者，以生育後期之稱抽穗期或齊穗期為中心較為嚴重。
1. Under greenhouse condition, the susceptility of every growth stages of rice to scierotial diseases was investigated. The late stage was found to be more susceptible. But it was more or less varied field. Under field condition, the increase in number of diseased, plants was more rapid in early growth stage, while during the. booting and heading stages the upward development of the diseases was mare conspicuous

No full text本省氣候高溫、多雨、濕度高，具有穀子發芽及霉菌繁殖的良好條件，在穀類乾燥及儲存上比較困難，因此如何減低穀粒含水量以抑制霉菌的繁殖及穀子本身的生存活動，使達休眠狀態，以利安全儲存，乃是穀類乾燥的重要課題，以往本省乾燥方法大都委之於天然力，利用不需花錢的太陽熱及自然風作為乾燥稻穀的原動力，但此方法操作既苦又慢，且一旦遇上壞天候無太陽熱可資利用時，只有坐視稻穀蒙受發芽發霉的損失，故如何利用機器，克服自然提高溫度及風量以增進乾燥速率，實為當前穀類乾燥之機械化途經，基此原因乃設計一套裝置思從乾燥之基本試驗著手。
These equipments are used on the fundamental research of grains drying for the purpose of finding out how air temperature and air quantity influence the grains drying speed and the physical condition of grain.
1. The special designed air flow measurement which is constructed by a rectangular iron plate hanged in an air flowing pipe is used in the drying process because of it’s easy to be operated.
2. The special designed electric heater is used in the drying process because it’s temperature is easy to be controlled and it’s energy can be calculated precisely.
3. After passing from the small eye grids and straightener, the air flow is steady and the air temperature at every point of the pipe cross section is nearly in the same temperature degrees.
4. From the indicating temperature degrees on the dry bulb thermometers and the wet bulb thermometers on bottom and top of the grains containeer, we can calculate the air humidity before and after the air flows into the grain layers.
5. From the thermometers which hare been set up on wall of the grain container we can find out the temperature in every grain layer during the drying operation.
6. From the holes on wall of the grain container we can suck grains by using suck bag.
7. From the window on wall of the grain container we can see the grain color changed during drying operation when the grainsmoisture content is really high
