Respon Superovulasi pada Sapi Simental dengan Metode Sinkronisasi Gelombang Folikel Berbeda.
No full textSinkronisasi gelombang folikel penting dilakukan dalam penentuan waktu
yang tepat untuk memulai superovulasi pada sapi donor. Penelitian ini bertujuan
untuk mengkaji respon superovulasi dengan metode sinkronisasi gelombang
folikel berbeda pada sapi simental dengan metode ovsynch dan pemasangan
implan progesteron (cue-mate). Hasil penelitian menunjukkan persentase sapi
respon pada perlakuan ovsynch sebesar 83.33% dengan corpus luteum (CL)
14.83±10.59 dan sapi respon 100% dengan CL 13.00±9.16 pada perlakun cuemate.
Total embrio terkoleksi dan embrio layak transfer pada perlakuan ovsynch
(9.33±7.53 dan 2.08±2.02) tidak berbeda nyata (P > 0.05) dengan perlakuan cuemate
(10.66±9.97 dan 1.92±2.94). Persentase embrio tidak layak transfer pada
kedua perlakuan (ovsynch = 77.68%; cue-mate = 83.03%) lebih tinggi
dibandingkan dengan embrio layak transfer (ovsynch = 22.32%; cue-mate =
17.97%). Disimpulkan bahwa sinkronisasi gelombang folikel dengan
menggunakan metode ovsynch dan cue-mate memiliki efek yang tidak berbeda
nyata terhadap respon superovulasi pada sapi simental
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
Superovulation Level in Some Cattle Breeds with Different Source of Follicle Stimulating Hormone (FSH)
No full textDemand for beef and milk will continue to increase along with population growth. But the increases of demand are not proportional to the population growth of beef and dairy cattle. Attempt to improve livestock population especially cattle population can be done by developing biotechnology of animal science such embryo transfer system. This study aimed to evaluate the effects of variations source Follicle Stimulating Hormone (FSH) to superovulation in cattle which includes Response Rate, total of Corpus Luteum (CL), CL ratio, total of embryos and Recovery Rate. This research has been carried out for three months, from April 2011 to June 2011. Research conducted at the Balai Embrio Ternak (BET) Laboratory located in the Cipelang Village, Cijeruk district, Bogor. The research was conducted using data of embryos production obtained from BET Cipelang. The data contains in vivo embryo production during 2009 to 2010. The data include semen used, FSH used in superovulation, total of CL, total of embryos grade A, B, C, D, and Unfertilized (UF). Ninety cows were used in the research, consisting of twenty-nine Holstein Friesian (HF), twenty-three Simmental, twenty-seven Limousin and eleven Angus. The data obtained is processed by the method of Randomized Block Design (RBD) factorial 3x5 pattern with 2 factors consist FSH source (Folltropin-V, Opti-Stim and Ovagen) and cattle breeds (HF, Simmental, Limousin and Angus). Based on the research, data showed that breeds of cattle gives significantly effect (p<0,05) to the Response Rate, Recovery Rate, total of CL and total of embryo and ovum collected. The source of FSH didn’t gives significantly effect on Response Rate, total of CL, ratio of CL, total of embryos and Recovery Rate.Permintaan daging dan susu sapi akan terus meningkat seiring dengan pertumbuhan penduduk. Namun peningkatan tersebut tidak sebanding dengan perkembangan populasi sapi potong dan sapi perah. Upaya peningkatan populasi ternak khususnya ternak sapi dapat dilakukan dengan mengembangkan bioteknologi di bidang peternakan yang salah satunya adalah sistem transfer embrio. Penelitian ini bertujuan untuk mempelajari pengaruh pemberian variasi sumber Follicle Stimulating Hormone (FSH) terhadap tingkat superovulasi pada beberapa bangsa sapi yang meliputi Response Rate, total Corpus Luteum (CL), total embrio dan ovum terkoleksi serta Recovery Rate. Penelitian ini telah dilaksanakan selama tiga bulan, yaitu mulai bulan April 2011 hingga bulan Juni 2011. Penelitian dilaksanakan di Laboratorium Balai Embrio Ternak (BET) yang terletak di Desa Cipelang, Kecamatan Cijeruk, Kabupaten Bogor. Penelitian ini dilakukan dengan menggunakan data sekunder produksi embrio yang diperoleh dari BET Cipelang. Data tersebut berupa catatan produksi embrio secara in vivo selama tahun 2009 sampai tahun 2010. Data tersebut meliputi semen yang digunakan, FSH yang digunakan dalam superovulasi, jumlah CL, jumlah embrio grade A, B, C, D, dan ovum tidak dibuahi atau Unfertilized (UF). Ternak sapi donor yang digunakan dalam penelitian ini sebanyak 90 ekor sapi, terdiri atas 29 ekor sapi Friesian Holstein (FH), 23 ekor sapi Simmental, 27 ekor sapi Limmousin dan 11 sapi Angus. Data yang didapatkan diolah dengan metode Rancangan Acak Lengkap (RAL) pola faktorial 3x4 dengan 2 faktor yaitu sumber FSH (Folltropin-V, Opti-Stim dan Ovagen) dan bangsa sapi (FH, Simmental, Limousin dan Angus). Berdasarkan hasil penelitian menunjukkan bahwa bangsa sapi memberikan pengaruh nyata (p<0,05) terhadap Response Rate, total CL dan total embrio dan ovum terkoleksi serta Recovery Rate. Sumber FSH tidak berpengaruh nyata pada Response Rate, total CL, rasio dari CL, total embrio dan Recovery Rate. Kata-kata kunci : superovulasi, transfer embrio, bangsa sapi
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
