Bu çalışmada fesleğen (Ocimum basilicum L.) bitkisinin O. basilicumManavgat, Dark Opel ve Antalya Geniş Yaprak çeşitlerinin 5-12 günlük in vitro koşullarda çimlenen fideciklerinden elde edilen yaprak, hipokotil, epikotil, sürgün ucu ve kotiledon boğum eksplanları in vitro koşullarda farklı sitokinin (BAP, TDZ) ile oksin (NAA, IBA) içeren MS ortamında sürgün rejenerasyonu için kültüre alınmıştır. Ortamlarda ilave olarak 1,0 mg/l PVP ve 3,0 g/l aktif kömür de kullanılmıştır. Tüm eksplantlarda kallus oluşumu ile kararma da gözlenmiştir. Her üç çeşitte sürgün oluşumu yalnız , hipokotil eksplantından elde edilmiştir. Manavgat ve Dark Opel çeşitlerinde eksplant başına en fazla sürgün 2,66 ve 6,58 adet sürgün 1,0 mg/l BAP içeren MS ortamında kaydedilirken, Antalya Geniş Yaprak çeşidinde eksplant başına en fazla sürgün 5,17 adet 2,0 mg/l TDZ içeren ortamdan elde edilmiştir. Antalya Geniş Yaprak ve Dark Opel çeşitlerinde sırasıyla 8,71 cm ve 6,51cmlik en uzun sürgünler kotiledon boğum eksplantından 0,10 mg/l TDZ ve 0,20 mg/l TDZ+0,10 mg/l IBA içeren MS ortamlarında kaydedilmiştir. Bazı sürgünlerde adventif kök oluşumu gözlenmiş olup, toprağa aktarılmıştır. Elde edilen köksüz sürgünler 0,25-1,00 mg/l IBA içeren MS ortamında köklendirilmiştir. Her iki türden köklenmiş bitkilerin adaptasyonu iklim odasında başarıyla sağlanmıştır.O. bacilium is an important medicinal and aromatic plant that shows wide variation in morphological characteristics and chemical contents. In this study, leaf, hypocotyl, epicotyl, cotyledonary nodes and shoot meristem explants of Manavgat, Dark opel and Antalya broad leaf cultivars of Basil (Ocimum basilicum L.) were taken from 5-12 days old in vitro grown seedlings and were cultured on MS medium supplemented with various concentrations of cytokinins (BAP, TDZ) and auxins (NAA, IBA) for in vitro shoot regeneration. Medium was also supplemented with 1,0 mg/l PVP ve 3,0 g/l active carbon. Callus induction was recorded on all explant with necrosis. Maximum number of shoots per explants were induced on hypocotyl explants in three cultivars. Maximum number of shoots per expalnts of cv. Mavavgat (2,66) and Dark opel (6,58) Cv?s. were recorded on MS medium supplemented with 1,0 mg/l BAP; and 5,17 shoots per expalnt of Antalya broad leaf Cv were obtained on MS medium containing 2,0 mg/l TDZ. Maximum shoot length of 8,71 cm from leaf explant of Antalya broad leaf and Dark opel (6,51cm) were recorded on cotyledonary node expalnts cultuered on MS medium containing 0,10 mg/l TDZ and 0,20 mg/l TDZ+0,10 mg/l IBA respectively. Adventitous roots were observed on some shoots and directly transferred to soil. Unrooted shoots were rooted on culture medium containing 0,25-1,00 mg/l IBA. Both types of rooted plants were successfully acclimatised under growth room conditions
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
SCREENING OF THREE SAFFLOWER (Carthamus tinctorius L.) CULTIVARS UNDER BORON STRESS
Full text linkAasim, Muhammad/0000-0002-8524-9029; CIKILI, Yakup/0000-0002-0393-6248WOS: 000416066600011Excess of boron in soil and irrigation water is a serious constrain to crop production in many areas of the World as well as in Turkey. A pot experiment was carried out with to screen safflower cultivars in order to investigate the effects of boron toxicity stress on early growth and ions composition. Three safflower cultivars (Carthamus tinctorius cv. Balci, Yenice, Remzi Bey) were grown in pots containing alkaline and potassium rich soil, additionally supplemented with 0, 4, 8, 16, 32, 64 and 128 mg kg(-1) boron. Chlorophyll content of all cultivars decreased with excessive boron levels. Plant height, shoot fresh and dry weight significantly increased at 4 mg kg(-1) boron level followed by sharp decline with the other treatments. Boron content of cultivars increased and the highest amount was observed at 128 mg kg(-1) boron level. Sodium content of all cultivars gradually increased with increase in B concentration. Whereas, potassium and calcium content reduced with increased B. Phosphorus content of all cultivars were least at 128 mg kg boron level. Results revealed that cv. balci appeared to tolerant to boron in soil up to 32 mg kg(-1) and can be recommended for growing and breeding material for boron rich soils of Central Anatolia
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
