Analysis of land suitability and carrying capacity of rabbitfish (Siganus canaliculatus) culture in seagrass ecosystem in coastal areas of Barru District, South Sulawesi
Authors: Rauf Abdul 
Published: July 2019

Rabbitfish (Siganus canaliculatus) are found in seagrass beds so that they have the potential to be cultivated in the ecosystem. Cultivation activities require appropriate environmental / land requirements and support to be able to live and develop optimally. This study aims to analyze: (1) Suitability of rabbitfish cultivation land in seagrass ecosystem, (2) The carrying capacity of the land for rabbitfish cultivation in the seagrass ecosystem. This research was carried out in the coastal area of Barru Regency in March-April 2017. This study uses a method with the Remote Sensing Technology and Geographic Information Systems (GIS) approach. The types of data collected are oceanographic oceanic parameters consisting of physical factors (temperature, depth, current velocity, and turbidity), and chemical factors (salinity, pH and DO). The results of the study showed that the waters area was suitable ± 135.76 ha. Results estimation of the carrying capacity/capacity of the waters for rabbitfish cultivation with an area of about 81.46 ha or around 407,300 cultivation units or 5000 units / ha (assuming 1 unit of cultivation = 2 m2 (0,0002 ha).Keywords: land suitability, rabbitfish, carrying capacity

Authors: Mustafa Muhammad Fadhil , Bunga Margaretha , Achmad Marlina 
Published: July 2019

The consequence of super intensive shrimp farming is an increase in aquaculture waste and disease transmission. Vibrio sp. Bacteria is a disease-causing agent in shrimp larvae when the shrimp is in a state of stress and weakness, and can cause death. The application of probiotics, namely beneficial microorganisms can degrade organic matter, reduce disease, and help accelerate the process of nutrient cycles as a consequence of super intensive shrimp farming. Commercial probiotics currently available are a mixture of several types of beneficial microorganisms, namely Bacillus sp., Pseudomonas sp., Nitrosomonas sp., Aerobacter sp., and Nitrobacter sp. The purpose of this study was to evaluate the use of probiotics with different time intervals to produce a decrease in the population of Vibrio sp. The research method applied was the treatment of commercial probiotics at different intervals of three, five, and seven days and without the administration of probiotics as controls. Furthermore, the bacterial population was calculated by total plate count (TPC). The results showed that the administration of probiotics had a significant effect on the decrease in the population of Vibrio sp. Provision of probiotics three days apart showed a decrease in the number of bacterial populations that were significantly different from the controls, but the same as the administration of intervals of five and seven days. The decrease in the number of bacterial populations in the treatment interval of three, five, and seven days in a row is 0.05 x , 0.41 x , and 0.61 x CFU / ml. This study recommends that the use of commercial probiotics intervals of seven days for super intensive vaname shrimp farming. The use of probiotics for three days indicates an impact on the increase in expenditure costs for probiotics. Commercial probiotic studies modified with natural microorganisms are thought to be able to streamline the operational costs of shrimp farming.Keywords: Vibrio sp. bacteria, probiotics, vaname shrimp, super intensive cultivation

Abstract
The presence of massive quiescent galaxies at high redshifts is still a challenge for most models of galaxy formation. The aim of this work is to compare the observed number density and properties of these galaxies with the predictions of state-of-the-art models. The sample of massive quiescent galaxies has been selected from the COSMOS2015 photometric catalog with z
phot ≥ 2.5,

, and a specific star formation rate (sSFR) of

. The photometric spectral energy distributions (SEDs) of the selected galaxies have been thoroughly analyzed based on different stellar population synthesis models. The final sample includes only those galaxies qualified as quiescent in all SED fitting runs. The observed properties have been compared to theoretical models: the number density of quiescent galaxies with

is reproduced by some models, although there is a large scatter in their predictions. Instead, very massive

are underpredicted by most of the current models of galaxy formation: some of them, built on the CARNage simulation, are consistent with data up to z ∼ 4, while at higher redshifts the volume of the considered simulation is too small to find such rare objects. Simulated galaxies that match the observed properties in the sSFR–M
* plane at z ∼ 3 have been analyzed by reconstructing their evolutionary paths: their merger trees suggest that AGN feedback could be the key process allowing for a rapid quenching of the star formation at z ≳ 4 and that its treatment should be improved in models.
Linguistique – récits – narratologie
Authors: Adam Jean-Michel 
Published: July 2019

Les récits ne concernent-ils que la narratologie ou peuvent-ils intéresser aussi la linguistique ? Si l’on considère que l’objet de la linguistique est la langue et que la phrase est sa limite maximale d’investigation, alors les récits ne sont pas un objet linguistique. Mais si la linguistique ne s’arrête pas à la phrase, alors le récit peut être l’objet de ce que R. Barthes appelait, à la suite d’É. Benveniste, une « linguistique du discours » ou « translinguistique ». La narratologie limite ses investigations à la narrativité et aux différentes formes de mise en récit, alors que, la linguistique du texte et du discours est une théorie générale dont le récit n’est qu’un objet d’étude parmi d’autres. Cet article monte que le passage prétendu de la « narratologie classique » à la « narratologie postclassique » est moins une révolution qu’une évolution prévisible. L’ancrage de R. Barthes dans la linguistique du discours d’É. Benveniste a rendu possible l’émergence d’une narratologie postclassique française, ce qui brouille les catégorisations actuellement en usage, fondées sur l’idée de rupture.
Un tournant animal dans la fiction française contemporaine ?
Authors: Milcent-Lawson Sophie 
Published: July 2019

Si le personnage animal appartient à l’évidence à une tradition littéraire qui remonte à l’Antiquité, les personnages animaux contemporains se distinguent de leurs prédécesseurs fictionnels en ce qu’ils ne sont pas conçus comme des projections allégoriques anthropomorphisées de l’humanité, mais pris au sérieux dans leur altérité comme dans leur individualité animales. Cette étude entend dégager d’un corpus de récits fictionnels contemporains certaines innovations narratives, énonciatives et stylistiques résultant du décentrement narratif et éthique qu’ils mettent en œuvre. Il s’agit en somme d’examiner la naissance, le plus souvent dans le cadre restreint de « séquences animalières », d’un récit non plus anthropocentré mais zoocentré.
A qualitative analysis of the Wikipedia N-Substate Algorithm's Enhancement Terms
Authors: Goslin Kyle , Hofmann Markus 
Published: July 2019

<p>Automatic Search Query Enhancement (ASQE) is the process of modifying a user submitted search query and identifying terms that can be added or removed to enhance the relevance of documents retrieved from a search engine. ASQE differs from other enhancement approaches as no human interaction is required. ASQE algorithms typically rely on a source of a priori knowledge to aid the process of identifying relevant enhancement terms. This paper describes the results of a qualitative analysis of the enhancement terms generated by the Wikipedia NSubstate Algorithm (WNSSA) for ASQE. The WNSSA utilises Wikipedia as the sole source of a priori knowledge during the query enhancement process. As each Wikipedia article typically represents a single topic, during the enhancement process of the WNSSA, a mapping is performed between the user’s original search query and Wikipedia articles relevant to the query. If this mapping is performed correctly, a collection of potentially relevant terms and acronyms are accessible for ASQE. This paper reviews the results of a qualitative analysis process performed for the individual enhancement term generated for each of the 50 test topics from the TREC-9 Web Topic collection. The contributions of this paper include: (a) a qualitative analysis of generated WNSSA search query enhancement terms and (b) an analysis of the concepts represented in the TREC-9 Web Topics, detailing interpretation issues during query-to-Wikipedia article mapping performed by the WNSSA.</p>
Protéger les capacités au travail: Réflexion éthique et politique à partir de l’œuvre de Martha Nussbaum
Authors: Ezvan Cécile 
Published: July 2019

Cet article propose une réflexion sur la protection des capacités au travail à partir de Martha Nussbaum. Sa visée est de penser les conditions institutionnelles de l’accès aux capacités, dans le cadre du travail, en mettant en évidence les points de tension entre l’approche des capacités et d’autres approches libérales, contractualiste ou utilitariste, qui structurent l’organisation du travail dans la société de marché.Libérale d’un point de vue politique dans la lignée d’Emmanuel Kant, tout en s’intéressant comme Aristote et à Karl Marx à la question des seuils et des libertés substantielles (et pas seulement formelles), Nussbaum permet de souligner dans le même temps les tensions qui traversent le travail contemporain et les conditions d’un développement humain au travail à partir d’une liste de capacités centrales et d’un seuil d’accès aux ressources nécessaires pour les mettre en œuvre.L’article s’appuie sur cette approche des capacités et la théorie de la justice de Nussbaum pour analyser les limites du droit, souligner les logiques institutionnelles qui conditionnent l’accès aux capacités au travail, et de distinguer les responsabilités collectives vis-à-vis du développement humain au travail.

Published: July 2019

The quality and stability of palm kernel oil (PKO) and cottonseed oil (CTSO) as affected by bleaching using modified oyster shell powder (OSP) and periwinkle shell powder (PSP) were evaluated by analysing their physicochemical properties. The two adsorbents potential was improved on by modification using 5 M HCl and H2SO4. The determinations of the parameters were carried out by titration, while the refractive index was determined using a refractometer. The results indicate that the saponification values (SV) of PKO and CTSO increase after bleaching. However, the result further shows that the peroxide values (PV) of bleached PKO using OSP and PSP modified with 5 M HCl decreased (17.49±0.01 and 20.04±0.08 respectively) and also the iodine values decreased (3.15±0.13 and 3.41±0.02 respectively).
The same decrease in PV and IV values is observed in PKO bleached using 5 M H2SO4. The values of PV for OSP and PSP are 4.99±0.005 and 12.77±0.77 respectively while the IV values for OSP and PSP are1.85±0.01 and 12.53±0.09 respectively. Also, 5 M HCl and H2SO4 modified OSP and PSP reduced the IV content in CTSO. (5 M HCl OSP and PSP are; 3.15±0.13 and 3.41±0.02 respectively while 5 M H2SO4 OSP and PSP values are; 3.33±0.04 and 3.13±0.06 respectively). The study revealed that the bleaching through the use of OSP and PSP influenced the components and properties of the PKO and CTSO, improved on their qualities and therefore, the adsorbents can serve as alternatives to the costly adsorbents available in the markets.

Published: July 2019

Background: The role of fertility as the most important determinant of demographic fluctuations has given more importance to its studies compared with other demographic phenomena. In this context, different indexes are used to measure fertility patterns where the index of the first birth after marriage has received much attention.
Materials and Methods: This was a cross-sectional (descriptive-analytic) study in which the fertility data of women are converted into a fictitious cohort and investigated. In this study, married woman in the age group of 15 to 49 years in 500 families in Hamedan were selected. In this study, a researcher-made questionnaire was used that included information related to the number of live births (fertility) and factors related to it (i.e. date of marriage, age, the first pregnancy, number of unwanted pregnancies, average interval between children, and the use of contraceptives). Univariate and multivariate survival analysis was carried out for the interval between marriage and the first birth. In the univariate section, using Kaplan-Meir method and log-rank test, survival functions of the interval between the first births after marriage in different predictive variables were compared.
Result: Mean age of mothers at the first birth was 22.04±4.357 years and mean number of live births was 2.18±0.904. The first marriage age of women, parental education, women’s employment, the use of contraceptives, and the number of live births were at a significance level of 5%.
Conclusion: It can be concluded that parental education, women’s employment, and use of contraceptives play important roles in population growth.

Published: July 2019

AbstractThis paper describes the synthesis of protein microtube motors having a urease interior surface and highlights their nonbubble‐propelled behavior driven by enzymatic reaction (urea→NH3 and CO2). The precursor microtubes were prepared by layer‐by‐layer assembly using a track‐etched microporous polycarbonate membrane. Immobilization of a urease on the internal wall was accomplished using avidin–biotin interaction. The tubules swam smoothly in an aqueous media containing a physiological concentration of urea. Each tubule was rotating laterally while moving forward. It is remarkable that the microtubes were digested completely by proteases, demonstrating perfect biodegradability.

Published: July 2019

AbstractIn this paper, the convergence speed of consensus for a second‐order integrator with the fixed undirected graph is investigated. Additionally, the quantized information and bounded control input are applied to the system. To accelerate the convergence speed, a distributed variable adjacency matrix is proposed where the links' weight are functions defined based on the distance to the neighbors. The stability of the whole system for both of the quantized and non‐quantized consensus protocol considering a general weight function is shown using Lyapunov's direct approach. Furthermore, it is mentioned that the consensus value of the position depends on the structure of the quantizer.

Published: July 2019

AbstractA comparative study was reported for both the effects of shape‐confined cubic Pd particle size (8, 13, and 21 nm) and surface property of most commonly used supports (SiO2, Al2O3, and silica‐alumina) on catalytic performance in the chemoselective hydrogenation of three model bio‐oil chemicals (benzaldehyde, acetophenone, and butyrophenone). The results showed that the size of Pd particles could be more associated with the hydrogenation reaction than acidities of the supports. Smaller size of Pd particles, regardless of the type of the support, provided the higher catalytic performance. XPS data showed that the electronic properties of Pd particles were similar, therefore, the possible reasons were the higher fraction of Pd atoms on corner in smaller particles, the lower accessibility of hydrogen atom to reactant on bigger particles, and the more low‐coordinated sites in the small‐size particles due to the short‐range ordering. In addition, Pd/SA catalysts (Brønsted acid sites on the support) showed the highest conversion and TOF compared to Pd/Al2O3 and Pd/SiO2 catalysts. This might be due to the enhanced the diffusion rates of the chemicals on the surface of the catalysts although they could not induce the ionic effect from the metal surface. Pd/SiO2 catalysts performed better than Pd/Al2O3 catalysts (Lewis acid sites on the support). The flexible SiOH groups on surface made the easy interaction with the metal particles and promote the reaction.
Concentrated Ionic‐Liquid‐Based Electrolytes for High‐Voltage Lithium Batteries with Improved Performance at Room Temperature

Published: July 2019

AbstractIonic liquids (ILs) have been widely explored as alternative electrolytes to combat the safety issues associated with conventional organic electrolytes. However, hindered by their relatively high viscosity, the electrochemical performances of IL‐based cells are generally assessed at medium‐to‐high temperature and limited cycling rate. A suitable combination of alkoxy‐functionalized cations with asymmetric imide anions can effectively lower the lattice energy and improve the fluidity of the IL material. The Li/Li1.2Ni0.2Mn0.6O2 cell employing N‐N‐diethyl‐N‐methyl‐N‐(2‐methoxyethyl)ammonium (fluorosulfonyl)(trifluoromethanesulfonyl)imide (DEMEFTFSI)‐based electrolyte delivered an initial capacity of 153 mAh g−1 within the voltage range of 2.5–4.6 V, with a capacity retention of 65.5 % after 500 cycles and stable coulombic efficiencies exceeding 99.5 %. Moreover, preliminary battery tests demonstrated that the drawbacks in terms of rate capability could be improved by using Li‐concentrated IL‐based electrolytes. The improved room‐temperature rate performance of these electrolytes was likely owing to the formation of Li+‐containing aggregate species, changing the concentration‐dependent Li‐ion transport mechanism.
On the capacity of the state‐dependent interference relay channel
Authors: Al‐qudah Zouhair , Musa Ahmed 
Published: July 2019

SummaryThis paper considers the state‐dependent interference relay channel (SIRC) in which one of the two users may operate as a secondary user and the relay has a noncausal access to the signals from both users. For discrete memoryless SIRC, we first establish the achievable rate region by carefully merging Han‐Kobayashi rate splitting encoding technique, superposition encoding, and Gelfand‐Pinsker encoding technique. Then, based on the achievable rate region that we derive, the capacity of the SIRC is established in many different scenarios including (a) the weak interference regime, (b) the strong interference regime, and (c) the very strong interference regime. This means that our capacity results contain all available known results in the literature. Next, the achievable rate region and the associated capacity results are also evaluated in the case of additive Gaussian noise. Additionally, many numerical examples are investigated to show the value of our theoretical derivations.

AbstractBackgroundAmeloblastomas of jaw in the pediatric population are a rare clinical entity and have not been well addressed in the literatures. The present retrospective study analyzed the risk factors associated with recurrence of pediatric ameloblastomas.MethodsCases of primary pediatric ameloblastomas seen in a tertiary hospital between 2005 and 2015 were analyzed to identify the clinical factors associated with recurrence.ResultsThere were a total of 104 cases of primary pediatric ameloblastomas. The overall mean maximum tumor diameter was 4.11 ± 1.339 cm. The receiver operating characteristic curve and the Youden Index showed an optimal cutoff point of 4.95 cm to accurately predict recurrence. Bone cortex/soft tissue invasion were associated with tumor recurrence (P < .001).ConclusionsThe maximum tumor diameter, root resorption, and bone cortex/soft tissue invasion were risk factors for recurrence of pediatric ameloblastomas. The new classification system may serve as a predictor of recurrence in pediatric ameloblastomas.

ScopeGut microbiota contributes to non‐alcoholic fatty liver disease (NAFLD) pathogenesis by multiple mechanisms not yet completely understood. Novel differential features between germ‐free mice (GFm) transplanted with protective or non‐protective cecal microbiota against NAFLD are investigated.Methods and resultsGut microbiota composition, plasma, and fecal bile acids (BAs) and liver mRNAs are quantified in GFm recipients from four donor mice differing in NAFLD severity (control diet, high‐fat diet [HFD]‐responder, HFD‐non‐responder, and quercetin‐supplemented HFD). Transplanted GFm are on control or HFD for 16‐weeks. Multivariate analysis shows that GFm colonized with microbiota from HFD‐non‐responder and quercetin supplemented‐HFD donors (protected against NAFLD) clusters together, whereas GFm colonized with microbiota from control and HFD‐responder mice (non‐protected against NAFLD) establishes another cluster. Protected phenotype is associated with increased gut Desulfovibrio and Oscillospira, reduced gut Bacteroides and Oribacterium, lower primary and higher secondary BAs in plasma and feces, induction of hepatic BA transporters, and repression of hepatic lipogenic and BA synthesis genes.ConclusionProtective gut microbiota associates with increased specific secondary BAs, which likely inhibit lipogenic pathways and enhance bile flow in the liver. This novel cross‐talk between gut and liver, via plasma BAs, that promotes protection against NAFLD may have clinical and nutritional relevance.
