Studi Manajemen Perkawinan Ternak Dengan Teknik Inseminasi Buatan (IB) Pada Sapi Madura Di UPT Pembibitan dan Kesehatan Hewan
Full text linkArtificial Insemination (AI) is a mating process, by unnaturally bringing sperm and egg cells together in female livestock (poultry and ruminants) with the help of human hands. The success of the AI technique is influenced by three main factors namely; livestock, cement and humans. UPT Livestock Breeding and Animal Health of Madura is one of the institutions for preserving Madura cattle germplasm, which further optimizes the AI program. The aim is to find out the factors that influence the success of Artificial Insemination, the process of detecting lust (estrus) and Artificial Insemination techniques. The method used in this study was direct observation using the artificial insemination method, namely rectovaginal. AI is an attempt to insert semen into the reproductive tract of female livestock using artificial tools and with human assistance or in other words marriages that are not carried out naturally. Detection of lust (Estrus) is the observation of signs of heat in a cow to be inseminated, detection of heat is an important factor in the process of artificial insemination because it determines the time for proper and successful mating. The AI technique in cattle is the rectovaginal method, in which the hand is inserted into the rectum and then holds the part of the cervix that is most easily identified because it has a hard anatomy, then the insemination gun is inserted through the vulva, into the vagina up to the cervix.Inseminasi Buatan (IB) adalah proses perkawinan, dengan mempertemukan antara sel sperma dan sel telur secara tidak alami yang dilakukan pada ternak betina (unggas dan ruminansia) dengan bantuan tangan manusia. Keberhasilan teknik IB dipengaruhi oleh tiga faktor utama yaitu; ternak, semen dan manusia. UPT Pembibitan Ternak dan Kesehatan Hewan Madura merupakan salah satu instansi pelestarian plasma nutfah sapi Madura, yang lebih mengoptimalisasikan program IB. Tujuannya untuk mengetahu faktor-faktor yang mempengaruhi keberhasilan Inseminasi Buatan, proses deteksi birahi (estrus) dan teknik Inseminasi Buatan. Metode yang digunakan dalam penelitian ini adalah pengamatan secara langsung dengan metode pada saat Inseminasi Buatan yaitu Rektovaginal. IB merupakan upaya memasukkan semen kedalam saluran reproduksi ternak betina dengan menggunakan alat buatan dan dengan bantuan manusia atau dengan kata lain perkawinan yang bukan dilakukan secara alami. Deteksi Birahi (Estrus) merupakan pengamatan terhadap tanda-tanda birahi pada sapi yang akan diinseminasi, deteksi birahi merupakan faktor penting dalam proses inseminasi buatan karena merupakan penentu waktu untuk melakukan perkawinan secara tepat dan berhasil. Teknik IB pada ternak sapi adalah dengan metode rektovaginal yaitu tangan dimasukkan kedalam rektum kemudian memegang bagian serviks yang paling mudah diidentifikasi karena mempunyai anatomi yang keras, kemudian insemination gun dimasukkan melalui vulva, ke vagina hingga ke bagian serviks
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
Venomics and biological analysis of Scatophagus argus argus (Spotted scat) venom isolated in Persian Gulf, extraction and purification of hemolytic protein
No full textGreen scat namely as Scatophagus argus argus is a venomous aquarium fish belonging to Scatophagidae family. It can induce painful wounds in injured hand with partial paralysis to whom that touch the spines. Dorsal and ventral rough spines contain cells that produce venom with toxic activities. According to unpublished data collected from local hospitals in southern coastal region of Iran, S. argus is reported as a venomous fish. Envenomation induces clinical symptoms such as local pain, partial paralysis, erythema and itching. In the present study green scat (spotted scat) was collected from Persian Gulf coastal waters. SDS-PAGE indicated 12 distinct bands in the venom ranged between 10-250 KDa. The crude venom had hemolytic activity on human erythrocytes (1%) with an LC100 (Lytic Concentration) of about 1.7 μg. The crude venom can release 813 μg proteins from 0.5% casein. Phospholipase C activity was recorded at 3.125 μg of total venom. Our findings showed that the edematic activity remained over 48 h after injection.The purification of the venom was done by HPLC and 30 peaks were obtained within 80 min but only one peak in 68 min retention time showed hemolytic activity at 90% acetonitril was isolated. The area percentage of the hemolytic protein showed that this hemolytic protein consist of 32 percent of total proteins and its molecular weight was 72 KDa in SDS_PAGE.The results demonstrated that crude venom extracted from Iranian coastal border has different toxic and enzymatic activities.PhDAdvisors:Shahla Jamili, Delavar Shahbazzadeh.

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
