Authors: Ariantini Fitri , Rosmawati Rosmawati , Kurniasih Titin 
Published: April 2020

Penelitian ini bertujuan untuk mengetahui pengaruh tingkat kesegaran IABS dalam formulasi pakan terhadap pertumbuhan ikan nila dibandingkan dengan formulasi pakan standar (pakan berbasis tepung ikan). Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 3 ulangan. Ikan nila yang digunakan memiliki berat rata-rata 5,23±0,02 gram dengan padat tebar 20 ekor per akuarium. Perlakuan pakan yang diberikan yakni pakan berbasis tepung ikan tanpa IABS, pakan mengandung IABS segar dan pakan mengandung IABS kurang segar. Parameter yang diukur adalah laju pertumbuhan spesifik (LPS), jumlah konsumsi pakan (JKP), efisiensi pakan (EP), tingkat kelangsungan hidup (SR) dan parameter kualitas air. Hasil penelitian menunjukkan bahwa ada perbedaan nyata (P<0,05) di antara perlakuan untuk parameter LPS dan EP, tetapi tidak berbeda nyata (P>0,05) untuk parameter JKP, SR dan kualitas air. Tingkat kesegaran bahan ikan asin sangat berpengaruh terhadap pertumbuhan dan efisiensi pakan untuk ikan nila, tetapi tidak untuk kelangsungan hidup ikan nila (Oreochromis niloticus). Pemberian IABS segar menghasilkan pertumbuhan dan efisiensi pakan yang sama baiknya dengan pakan standar dan lebih baik daripada pemberian IABS kurang segar. Kata kunci : IABS, protein, ika nila, pertumbuhan, tepung ikan.

APPLICATION OF CRISPR ACTIVATION (CRISPRa) SYSTEM TO ZEBRAFISH (Danio rerio) GENES
Authors: Putri Rizka Rahmana 
Published: April 2020

CRISPR activation system is part of the function of CRSPR/Cas9 which is used to manipulate certain genes by activating these genes. CRISPR activation utilizes dCas9 (dead-Cas9) or Cas9 which is deactivated as DNA scissors, so that the use of Cas9 for gene activation does not cause targeted DNA chain termination. This research that uses this CRISPR activation is applied to the zebrafish gene (Danio rerio) aims to determine the mRNA level of the targeted gene. In this study, the ASCL1a and BCL6a genes from zebrafish were targeted as the object of study. The results showed that genes from zebrafish that were targeted had an increase in mRNA levels after being activated using CRISPR activation system. Keywords: CRISPR activation system (CRISPRa), zebrafish (Danio rerio), dCas9, ASCL1a gene, BCL6a gene

A decision-making method based on Bayesian optimization algorithm for small modular reactor
Authors: Zhang B. , Peng M. , Cheng S. , Sun L. 
Published: April 2020

Abstract
Small modular reactors (SMRs) are suitable for deployment in isolated underdeveloped areas to support highly localized microgrids. In order to achieve almost autonomous operation for reducing the cost of operating personnel, an autonomous control system with decision-making capability is needed. In this paper, a decision-making method based on Bayesian optimization algorithm (BOA) is proposed to explore the optimal operation scheme under fault conditions. BOA is used to adjust exploration strategy of operation scheme according to observations (operation schemes previously explored). To measure the feasibility of each operation scheme, an objective function that considers security and economy is established. BOA attempts to obtain the optimal operation scheme with maximum of the objective function in as few iterations as possible. To verify the proposed method, all main pump powered off fault is simulated by RELAP5 code. The optimal operation scheme of the fault is applied, the transient result shows that all key parameters are within safe limits and SMR is maintained at relatively high power, which means that BOA has the decision-making capability to get an optimal operation scheme on fault conditions.
Durkheim en réunion (1ère partie)
Authors: Béra Matthieu 
Published: April 2020

*Full article is in FrenchEnglish abstract:
Thanks to an original archive, this article aims to characterize Durkheim’s interventions at the Council of Professors in Bordeaux from 1887 to 1902. Frequency, tonality and above all the subjects of interest of his interventions are studied. We are able to see that he paid great attention to the students and their education (i.e. their courses, fees, grants, the problem of the predominance of Latin, proposals for reform of the competitive agrégation in philosophy) but that he was also interested in administrative subjects (modalities of attribution of new courses and new chairs, procedures of the council) and research subjects (subscriptions for the university library, life of the historical and local Annales du Midi). We finally discover that he certainly had administrative ambitions – to become the dean – ended by political circumstances (the Dreyfus Affair).French abstract:
Cet article vise à caractériser les interventions de Durkheim aux assemblées des professeurs de la Faculté de Lettres de l’université de Bordeaux entre 1887 et 1902 en se référent à une archive inédite. Sont présentées les fréquences, la tonalité et surtout ses domaines d’interventions. On voit qu’il s’intéresse d’abord aux étudiants et à leurs études (ouverture ou fermeture des cours, attribution des bourses, droits d’inscription, problème de la prédominance du latin, réforme de l’agrégation de philosophie), mais aussi aux questions administratives (attribution des chaires, fonctionnement du conseil de l’université), et aux questions liées à la recherche (abonnements en revues à la Bibliothèque universitaire, vie de la revue antiquisante des Annales du midi). On découvre qu’il n’était pas dépourvu d’ambitions administratives, que les circonstances politiques (l’affaire Dreyfus) vinrent contrarier.

Background: Breast tuberculosis is a rare extra pulmonary tuberculosis presentation usually misdiagnosed as carcinoma, pyogenic abscess or idiopathic granulomatous mastitis. Detection of tubercular bacilli by ZN stain, culture and CBNAAT along with caseating granuloma on histopathology helps in diagnosis.
Aims and Objectives: To study the clinico-pathological characteristic of breast tuberculosis and diagnostic accuracy of CBNAAT for early and specific diagnosis in reference to histopathological test
Material and Methods: 38 cases of BTB between August2012 to July 2017 were studied. Culture for acid-fast bacilli, smear positivity on Z-N staining, CBNAAT, and cytological and histological examination was done for confirmation.
Results: Prevalence of BTB in this study was found to be 3.95% .The risk factors were reproductive age (20-35), multiparity, lactation and low socioeconomic status. Unilateral lump in the upper outer and central quadrant of the breast was the commonest observation. Only 34.2% were diagnosed provisionally as BTB rest 73.68% were misdiagnosed as fibroadenoma, breast abscess and malignancy Clinically nodulo-caseous variety(55.6 %) disseminated (18.4%) and tubercular abscess (26.3%) were seen. Sensitivity of ZN staining, culture, FNAC and histopathology is 15.8%,5.8%, 74% ,100%respectively. Sensitivity, specificity, positive predictive value, and negative predictive value for the CBNAAT test were 81.818%, 93.103%, 93.10%, and 81.82% respectively.39.4% were cured completely with ATT with 60.52% with residual lesions needed surgery
Conclusion: This study highlights the importance of early diagnosis and aggressive medical and if required surgical management to cure this disease. CBNAAT should be used as an additional test to conventional smear microscopy, culture, FNAC and histology.
