Experiments On The Chemical Control For Diseases Of Cultivated Mushroom (Agaricus Bisporus)
No full text本實驗自1964年至1966年之間，在臺灣省農業試驗所植物病理系，為選擇洋菇腦菌病防治上有效藥劑，及研究其有效使用方法，而舉行本實驗，並希望找出能防止腦菌病兼而對其他病原菌能同時收效之藥劑。玆將結果摘錄如下：
1.綿線法實驗結果，選出Brestan-60，Dithane M-22，Dithane M-53種藥劑有效。
2.Zentmyer氏土攘藥劑試驗法，淘汰Brestan-60，Dithane M-22兩種能被土攘分解之藥劑。
In order to select the effective chemicals for the control of truffle disease of mushroom and to find out the proper use of them for the control of the disease, the experiments were carried out from 1964 to 1966 in the laboratory of Department of Plant Pathology, Taiwan Agricultural Research Institute, Taipei, Taiwan. It was found that these chemicals can control not only truffle disease but also the other diseases.
The results are summarized as follows:
1. The result of the screening test with cotton string method showed that Brestan-60, Dithane M-22 and Dithane M-45 effectively inhibit the growth of the causal fungus of truffle disease, at the concentration of 500 ppm.
2. However, it was also found that Brestan-6o, Dithane M-22 and Dithane M-45 were absorpted by soil (Zentmyer’s laboratory method). The only chemical found to be effective for control the growth of truffle fungus was Dithane A-40

2.鹽類如NaCl及（NH4）2SO4濃度4N以上處理腦菌病病原菌子囊果3小時以上，可因其滲透壓之作用抑制其生長。
3.60℃乾濕熱處理洋菇各種病原菌除Mucor, Thielavia sp.及Trichoderma sp.外，其餘處理2小時以上，即達其致死程度。
4.Trichoderma sp.分泌之Toxin證實對洋菇腦菌病病原菌有促進生長與發育之趨勢，但在相同情況下，對洋菇則否。
5.洋菇以547品系對Trichoderma sp.之抗性最強次為542、543品系541最弱，培養基中含20%以上之Trichoderma sp.汁液即顯著影響洋藷菌絲生長。
Ammonium nitrogen was failure to be utilized as sources of nitrogen by pathogen of truffle disease (Diehliomyces microsporus). but it was generally used to support the growth of cultivated mushroom (Agaricus bisporus). Only nitrate nitrogen could be used by Diehliomyces microsporus. That was a significant different about nitrogen nutrition between cultivated mushroom and truffle disease.
The addition of the solution of salts as NaCl and (NH4)2SO4 at the concentration above 4N to ascocarps. of Diehliomyces microsporus, could control the growth of the fungus. Most mushroom diseases pathogens were killed with heat(140°F) under moist and dry condi-tions. Exceptions are Thielavia sp.,Mucor sp. and Trichoderma sp.
A metabolic product as toxin of Trichoderma sp. had been testified that it could promote the development of the causal organism, but under the same conditions it was ineffective to growth of cultivated mushroom furthermore it decresed the yield.
In regard with the resistance of several varieties of cultivated mushroom to Trichoderma sp., this experiment was proved that 547 (303) variety was the best one. 542 and 543 variety came next and 541 variety came after that. If the medium contained above 20% of the filtrate Trichoderma sp., it had great influented on growth of hyphae of cultivated mushroom
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
