Published: April 2018

AbstractThis study describes a statistical approach of watercourses hydrological regimes in flood, taking into account the latter duration d and return period T. The choice of Middle Cheliff watershed as study area is linked to disasters strong return period in the western region of Algeria. The Midlle Cheliff catchment basin, located in northwest Algeria, has particularly experienced severe floods over the last years. In view of the recurrence of these unusual events, the estimation and the predetermination of floods extreme quantiles are a strategic axis for prevention against floods in this region. The a curves are first of all locally determined, directly from a statistical analysis of flow continuously exceeded during a duration d (QCXd) on different durations from available data of the study region. Then, these curves are compared to those obtained by application of different regional models VFS (Vandenesse, Florac and Soyans) in which two indices of the watershed characteristic flood are taken into account, a descriptive duration of the flood dynamics (D) and the instantaneous maximal annual flow of 10 year return period (QIXA10). The final choice of the model is based on verification of certain criteria, such as: Nash and the root mean squared error (RMSE). The closest regional models to the local ones are Florac’s for low duration and return periods, and Vandenesse’s for large return periods, for different durations. These results could be used to build regional Q-d-F curves on ungauged or partially gauged Algerian basins.

Chlorophyll Pigment Concentration and Sea Surface Temperature of the Black Sea
Authors: KAVAK Mehmet Tahir 
Published: April 2018

As an enclosed sea, the Black Sea has countless economic activities (mainly tanker traffic and fisheries) and recreational activities, with the consequence of being threatened by dramatic dangers and pollution. Optical remote sensing can provide a novel look at physical processes and then driving mechanisms. It is worthwhile to know how the temperature and other marine parameters change on seasonal and long-term scales. In the paper CZCS (Coastal Zone Color Scanner) and AVHRR (Advanced Very High Resolution Radiometer) satellite were used to study the relationship between photosynthesis and SST since phytoplankton forms the very lowest clement in the marine ecosystem. Satellite derived data could provide information on the amount of sea life present in any given area throughout the world. The information could also be useful in connection with studies of global changes m temperature and what effect they could have on the total abundance of marine life. Present work which used CD-ROM set from NASA did not found evidence of correlation between chlorophyll pigment concentration and SST of the Black Sea with 99.95% certainty, three channel algorithm or the use of fluorescence or chlorophyll absorption peak in the red suggested for future work.

Published: April 2018

The study was aimed to determine the existing status of extension services provided for agricultural risk management in making use of Information and Communication Technologies (ICTs). There were 360 farmers selected through multistage cluster sampling technique and data were collected from four areas of Malaysia. The results reveal that farmers could get limited information from extension staff on the use of ICTs for disaster information. Moreover, most of the farmers still could not get support from extension staff to integrate ICTs for agricultural risk management. Farmers highlighted that extension staff need training to improve their capacity. Therefore, public and private sector should initiate various training programs firstly for the extension field staff and then diffuse various management skills and techniques into farmer fields for better agricultural risk management using ICTs.
Inter-religious relations in Yorubaland, Nigeria: corpus methods and anthropological survey data
Authors: Nolte M. Insa , Ancarno Clyde , Jones Rebecca 
Published: April 2018

This paper uses corpus methods to support the analysis of data collected as part of a large-scale ethnographic project that focusses on inter-religious relations in south-west Nigeria. Our corpus consists of answers to the open questions asked in a survey. The paper explores how people in the Yoruba-speaking south-west region of Nigeria, particularly Muslims and Christians, manage their religious differences. Through this analysis of inter-religious relations, we demonstrate how corpus linguistics can assist analyses of text-based data gathered in anthropological research. Meanwhile, our study also highlights the necessity of using anthropological methods and knowledge to interpret corpus outputs adequately.We carry out three types of analyses: keyness analysis, collocation analysis and concordance analysis. These analyses allow us to determine the ‘aboutness’ of our corpus. Four themes emerge from our analyses: (1) religion; (2) co-operation, tolerance and shared communal values such as ‘Yoruba-ness’; (3) social identities and hierarchies; and (4) the expression of boundaries and personal dislike of other religious practices.
On the Terminal Rotation Rates of Giant Planets
Authors: Batygin Konstantin 
Published: April 2018

Abstract
Within the general framework of the core-nucleated accretion theory of giant planet formation, the conglomeration of massive gaseous envelopes is facilitated by a transient period of rapid accumulation of nebular material. While the concurrent build-up of angular momentum is expected to leave newly formed planets spinning at near-breakup velocities, Jupiter and Saturn, as well as super-Jovian long-period extrasolar planets, are observed to rotate well below criticality. In this work, we demonstrate that the large luminosity of a young giant planet simultaneously leads to the generation of a strong planetary magnetic field, as well as thermal ionization of the circumplanetary disk. The ensuing magnetic coupling between the planetary interior and the quasi-Keplerian motion of the disk results in efficient braking of planetary rotation, with hydrodynamic circulation of gas within the Hill sphere playing the key role of expelling spin angular momentum to the circumstellar nebula. Our results place early-stage giant planet and stellar rotation within the same evolutionary framework, and motivate further exploration of magnetohydrodynamic phenomena in the context of the final stages of giant planet formation.
Black Hole Mergers in Galactic Nuclei Induced by the Eccentric Kozai–Lidov Effect
Authors: Hoang Bao-Minh , Naoz Smadar , Kocsis Bence , Rasio Frederic A. , Dosopoulou Fani 
Published: April 2018

Abstract
Nuclear star clusters around a central massive black hole (MBH) are expected to be abundant in stellar black hole (BH) remnants and BH–BH binaries. These binaries form a hierarchical triple system with the central MBH, and gravitational perturbations from the MBH can cause high-eccentricity excitation in the BH–BH binary orbit. During this process, the eccentricity may approach unity, and the pericenter distance may become sufficiently small so that gravitational-wave emission drives the BH–BH binary to merge. In this work, we construct a simple proof-of-concept model for this process, and specifically, we study the eccentric Kozai–Lidov mechanism in unequal-mass, soft BH–BH binaries. Our model is based on a set of Monte Carlo simulations for BH–BH binaries in galactic nuclei, taking into account quadrupole- and octupole-level secular perturbations, general relativistic precession, and gravitational-wave emission. For a typical steady-state number of BH–BH binaries, our model predicts a total merger rate of ∼1–3

−3

−1, depending on the assumed density profile in the nucleus. Thus, our mechanism could potentially compete with other dynamical formation processes for merging BH–BH binaries, such as the interactions of stellar BHs in globular clusters or in nuclear star clusters without an MBH.
