(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 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
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
