Published: July 2019

Penempatan reef ball di perairan Teluk Buyat dan sekitarnya telah dilakukan pada tahun 1999 oleh PT. Newmont Minahasa Raya. Tujuan penempatan reef ball untuk membangun habitat berbagai biota yang berasosiasi dengan karang sehingga dapat meningkatkan populasi ikan ekonomis penting. Kehadiran ikan karang pada reef ball sangat penting secara ekologis dan ekonomis. Penurunan kualitas terumbu berarti hilangnya nilai ekonomi barang dan jasa, serta hilangnya jaminan makanan dan pekerjaan untuk masyarakat pesisir, yang umumnya hidup dalam kemiskinan. Secara keseluruan, komposisi spesies ikan yang ditemukan di reef ball terdiri dari 19 famili, 34 genus, 50 spesies dan 290 individu, yang tertinggi dihuni oleh jenis dari famili Mullidae. Seiring dengan bertambahnya waktu dan usia reef ball, beberapa spesies terlihat sudah menetap seperti Lutjanus kasmira, dan beberapa spesies dari famili Acanthuridae. Keberadaan reef ball membantu terbentuknya ekosistem terumbu karang yang baru dan meningkatkan kesuburan perairan, sehingga lebih meningkatkan keberadaan komposisi ikan karang, yang pada akhirnya meningkatkan pendapatan nelayan dari hasil tangkapan ikan karang.Kata kunci: Reef ball, karang batu, ikan karang Distribution of Coral Reefs and Fish in Buyat Bay Area Reef Ball Southeast Minahasa Regency The placement of reef ball in Buyat Bay and surrounding areas have been carried out since 1999 by PT. Newmont Minahasa Raya. The goal of this placement was to build a habitat for many biota associated with reef thus may improve economically important fish populations. The presence of reef fish on the reef ball is indispensable ecologically and economically. Furthermore, the degradation of reefs might cause the disappearance of economic value of goods and services, as well as the disappearance of food security and employment for coastal communities, who generally live in poverty. Overall, the composition of fish species found in the reef ball consists of 19 families, 34 genera, 50 species and 290 individuals, the highest inhabited by species of the family Mullidae. As time went by and the increase of reef ball age, some species seem have settled down such as Lutjanus kasmira, and several species of the Acanthuridae family. In addition, the presence of reef ball helps the formation of a new coral reef ecosystem and increase the fertility of waters, therefore enhancing the presence of reef fish composition, which might increases the income of fishermen.

Authors: Paruntu Carolus , Rifai Husen , Kusen Janny D 
Published: July 2019

Nematosit dari tiga spesies karang Scleractinia, yaitu Pocillopora eydouxi, Pocillopora woodjonesi dan Pocillopora verrucosa yang mendiami terumbu karang di kawasan Pantai Malalayang, Manado, Pro­vinsi Sulawesi Utara diteliti dalam penelitian ini. Dari 25 tipe nematosit utama yang dikenal dalam filum Cnidaria, dua tipe di antaranya dijumpai pada ketiga spesies ini. Dua tipe utama nematosit, yaitu holotrichous isorhizas (HI) dan microbasic p-mastigophores (MpM) teramati pada P. eydouxi dan P. woodjonesi, dan hanya satu tipe, yaitu microbasic p-mastigophore (MpM) diamati pada P. verrucosa. Komposisi nematosit pada P. eydouxi serupa dengan P. woodjonesi, tetapi sangat berbeda dari P. verrucosa. Ukuran HI adalah berbeda antara P. eydouxi dan P. woodjonesi, dan juga ukuran MpM berbeda antara P. verrucosa dan P. eydouxi atau P. woodjonesi. Hasil pengamatan menunjukkan bahwa komposisi dan dimensi nematosit cenderung bervariasi di antara ketiga spesies ini, walaupun berada dalam satu genus. Perbedaan-perbedaan dalam nematosit ini diusulkan untuk dapat digunakan dalam klasifikasi karang. Kata kunci: Pocillopora eydouxi, Pocillopora woodjonesi, Pocillopora verrucosa, nematosit, holotrichous isorhizas (HI), microbasic p- mastigophore (MpM). Nematocysts of three Scleractinian corals, i.e., Pocillopora eydouxi, Pocillopora woodjonesi and Pocillopora verrucosa occurring in the reef of the coastal area of Malalayang, Manado, North Sulawesi Province were studied. Of the 25 major types of nematocysts recognized in the phylum of Cnidaria, two types were encountered in these three corals. Two major types of holotrichous isorhizas (HI) and microbasic p-mastigophores (MpM) were observed in P. eydouxi and P. woodjonesi, and only one type of microbasic p-mastigophore (MpM) was observed in P. verrucosa. The nematocyst composition of P. eydouxi was similar to that of P. woodjonesi, but markedly different from that of P. verrucosa. The size of HI was different between P. eydouxi and P. woodjonesi, and also the size of MpM was different between P. verrucosa and P. eydouxi or P. woodjonesi. The present observation showed that nematocyst composition and dimension might be varied among these three corals. It is suggested that the differences in the nematocysts could be used in the classification of corals. Keywords: Pocillopora eydouxi, Pocillopora woodjonesi, Pocillopora verrucosa, nematocysts, holotrichous isorhizas (HI), microbasic p- mastigophore (MpM).

While the measurement time of each - each tube obtained the smallest error on the tube-to-one by 0 , 03%, and the biggest error of measurement contained in the tube to the fourth, fifth, sixth, eighth and tenth of 0.16%.
The Effect of General Relativistic Precession on Tidal Disruption Events from Eccentric Nuclear Disks
Authors: Wernke Heather N. , Madigan Ann-Marie 
Published: July 2019

Abstract
An eccentric nuclear disk consists of stars moving on apsidally aligned orbits around a central black hole. The secular gravitational torques that dynamically stabilize these disks can also produce tidal disruption events (TDEs) at very high rates in Newtonian gravity. General relativity, however, is known to quench secular torques via rapid apsidal precession. Here we show that for a disk-to-black-hole mass ratio of

, the system is in the full loss-cone regime. The magnitude of the torque per orbital period acting on a stellar orbit means that general relativistic precession does not have a major effect on the dynamics. Thus we find no evidence that TDE rates from eccentric nuclear disks in the full loss-cone regime are affected by general relativistic precession. Furthermore, we show that orbital elements between successive TDEs from eccentric nuclear disks are correlated, potentially resulting in unique observational signatures.
On High-energy Particles in Accretion Disk Coronae of Supermassive Black Holes: Implications for MeV Gamma-rays and High-energy Neutrinos from AGN Cores
Authors: Inoue Yoshiyuki , Khangulyan Dmitry , Inoue Susumu , Doi Akihiro 
Published: July 2019

Abstract
Recent observations with ALMA have revealed evidence for nonthermal synchrotron emission from the core regions of two nearby Seyfert galaxies. This suggests that the coronae of accretion disks in active galactic nuclei (AGNs) can be conducive to the acceleration of nonthermal electrons, in addition to the hot, thermal electrons responsible for their X-ray emission through thermal Comptonization. Here, we investigate the mechanism of such particle acceleration, based on observationally inferred parameters for AGN disk coronae. One possibility to account for the observed nonthermal electrons is diffusive shock acceleration, as long as the gyrofactor η

g
does not exceed ∼106. These nonthermal electrons can generate gamma-rays via inverse Compton scattering of disk photons, which can appear in the MeV band, while those with energies above ∼100 MeV would be attenuated via internal γγ pair production. The integrated emission from all AGNs with thermal and nonthermal Comptonization can reproduce the observed cosmic background radiation in X-rays as well as gamma-rays up to ∼10 MeV. Furthermore, if protons are accelerated in the same conditions as electrons and η

g
∼ 30, our observationally motivated model is also able to account for the diffuse neutrino flux at energies below 100–300 TeV. The next generation of MeV gamma-ray and neutrino facilities can test these expectations by searching for signals from bright, nearby Seyfert galaxies such as NGC 4151 and IC 4329A.
Chemical and Kinematic Properties of the Galactic Disk from the LAMOST and Gaia Sample Stars

Published: July 2019

Abstract
We determined the chemical and kinematic properties of the Galactic thin and thick disk using a sample of 307,246 A/F/G/K-type giant stars from the LAMOST spectroscopic survey and Gaia DR2 survey. Our study found that the thick disk globally exhibits no metallicity radial gradient, but the inner disk (R ≤ 8 kpc) and the outer disk (R > 8 kpc) have different gradients when they are studied separately. The thin disk also shows two different metallicity radial gradients for the inner disk and the outer disk, and has a steep metallicity vertical gradient of

dex kpc−1, which becomes flat when it is measured at increasing radial distance. The metallicity radial gradient on the other hand becomes weaker with increasing vertical distance. Adopting a Galaxy potential model, we derived the orbital eccentricity of sample stars and found a downtrend of average eccentricity with increasing metallicity for the thick disk. The variation of the rotation velocity with the metallicity shows a positive gradient for the thick disk stars and a negative one for the thin disk stars. Comparisons of our observed results with models of disk formation suggest that radial migration could have influenced the chemical evolution of the thin disk. The formation of the thick disk could be affected by more than one process: the accretion model could play an indispensable role, while other formation mechanisms, such as the radial-migration or disk-heating model could also have a contribution.
Y a-t-il une géopolitique du nationalisme hindou ?
Authors: Racine Jean-Luc 
Published: July 2019

À la veille des élections législatives d’avril-mai 2019, l’heure du bilan a sonné pour le gouvernement de Narendra Modi. En matière de politique étrangère, on cherchera à éclairer ce bilan sous deux angles. Le premier fera l’inventaire des grands axes suivis depuis 2014, dans le voisinage proche marqué principalement par les tensions continues avec le Pakistan, mais aussi sur la scène mondiale où la multipolarité l’emporte sur le multilatéralisme. Dans l’un et l’autre champ, la montée en puissance de la Chine est un facteur structurant, qui explique l’intérêt de l’Inde pour le concept d’Indo-Pacifique, même si la règle reste la même, en faveur de partenariats, mais pas d’alliances. La deuxième approche rappelle ce que sont les fondements idéologiques du nationalisme hindou au pouvoir et s’interroge : cette idéologie a-t-elle marqué de façon décisive la géopolitique indienne sous le gouvernement Modi ? Pour nombre d’observateurs, au-delà des affichages du soft power , la continuité avec le gouvernement précédent reste forte.
Puissance et dépendance : l’Inde et les importations d’armement
Authors: Monsonis Guillem 
Published: July 2019

L’Inde est aujourd’hui un des principaux importateurs d’armement au monde, sa base industrielle et technologique de défense (BITD) étant incapable de couvrir l’ensemble des besoins des forces. L’analyse de ses principaux partenariats est un bon indicateur de la nature et du niveau des dépendances actuelles de l’industrie indienne. La Russie et Israël sont devenus des partenaires stratégiques de l’Inde en s’imposant comme des fournisseurs de confiance répondant rapidement à ses besoins capacitaires. Les achats d’armements aux États-Unis sont quant à eux essentiellement motivés par des raisons diplomatiques et parce que Washington propose des capacités indisponibles ailleurs. Afin de réduire cette dépendance aux importations difficilement tenable à terme, le gouvernement de Narendra Modi a lancé un programme visant à faire entrer le secteur privé dans la BITD et à favoriser la conception et la production locales d’armement. Une politique qui peine cependant à produire des résultats et qui se heurte à l’urgence et l’amplitude des besoins des forces.
De la démocratie délibérative à la démocratie radicale ? Tirage au sort et politique au XXI e siècle
Authors: Sintomer Yves , Saint-Upéry Marc 
Published: July 2019

Cet article soutient quatre thèses principales. La première est que ces dernières décennies, deux vagues d’innovations démocratiques basées sur le tirage au sort doivent être distinguées, s’appuyant sur des dispositifs concrets partiellement différents, incarnant des dynamiques sociales variées et dotés d’horizons démocratiques distincts. Le second argument est que la logique de la première vague d’innovations démocratiques reposant sur des mini-publics choisis au hasard se distingue notablement de la dynamique du tirage au sort politique à Athènes, car elle tend vers une dynamique de démocratie délibérative plutôt qu’une dynamique de démocratie radicale. À l’inverse, les processus de tirage au sort qui ont émergé durant la deuxième vague sont plus proches de l’esprit des traditions démocratiques radicales athéniennes. Le troisième argument est normatif : ces processus de sélection aléatoire avec pouvoir décisionnel sont plus prometteurs d’une véritable démocratisation de la démocratie. Enfin, le dernier argument soutient que tout projet de législatif tiré au sort doit s’inspirer de ces considérations au moment de défendre une perspective normativement convaincante et politiquement réaliste.
