Published: April 2018

Aquaculture especially shrimp farming has significant contribution to the economy of Bangladesh. The southwest coastal area is more prominent for commercial shrimp farming due to its auspicious environment, higher economic returns, nutrition value and for employment opportunity. The present study estimates the socioeconomic status and financial profitability of small-scale shrimp farming in selected areas of Khulna district. One hundred (100) shrimp farmers were selected and data were collected through direct interview method. Financial profitability was analyzed from the different point of view. The study revealed that about 35% farmers lie in prime working age group. Most of the farmers completed primary level of education while a few of them were illiterate. Family size of 65 % farmer’s was medium and 40% farmer’s main occupation was shrimp farming. Study also revealed that gross profit margin was high i.e. 59% indicating that farmers did well in managing their farm and farmers has more to cover for operating, financing and other cost. Break-even price for the small scale shrimp worked out Tk. 311 per kg while break-even production was found 155 kg per acre. Benefit cost ratio and net profit margin were found more than one and positive respectively, indicated that small scale shrimp farming was commercially profitable. The research concludes that there is ample scope and possibility for sustaining and developing the small scale shrimp farming in the coastal area of Bangladesh.J. Bangladesh Agril.

Généricité et implication, ou l'histoire, souvent déformée, d'un couple
Authors: Banys Wieslaw 
Published: April 2018

Tout d'abord, on se propose d'examiner l'analyse classique des raisons pour lesquelles on rapproche la généricité de l'implication, entendue d'une manière imprécise, comme c'est souvent le cas, et l'on démontre, entre autres, qu'elle peut se combiner aussi avec le quantificateur existentiel et que, par conséquent, l'une des raisons de formuler une histoire particulière (et "imprécise") du couple V / — » disparaît.
Ensuite, on se pose la question de savoir si les phrases du type (1) Les chats sont intelligents peuvent réellement être représentées par le couple V et une implication logique, en examinant le bien-fondé de l'analyse plus ou moins classique des défauts respectifs de V et — > dans la représentation de (1).
Enfin, on présente brièvement l'histoire non déformée du couple V / généricité et implications sémantique / nomologique nécessaires et celles du couple V / "généricité" et implication "contingente", non nécessaire, ce qui mène à représenter (1) à l'aide de (2) : (Vx) (x est un chat —> x est intelligent) où — » veut dire implication (contingente).
Aspect et autres catégories du verbe
Authors: Bednarczuk Leszek 
Published: April 2018

The morpho-syntactic categories of the verb can be reduced to the three semantic relations that refer the process expressed by the verb (1) to reality : moods, assertions (statuts), modal techniques, (2) to the participants : persons, voices, modes of meaning, and (3) to time : tenses, modes of action, aspects.
In the Slavic languages, the opposition between completed (perfective) and incompleted (imperfective) action is carried by-aspect, which occurs in finite, nonfinite and nominal forms of the verb (deverbativa). There are other languages in which this category has no relevant equivalents. However, if we consider grammatical aspect to be a temporal determination of sorts, we can include here the oppositions : anterior / simultaneous, proximate / distant, definite / indefinite, progressive / habitual action.
Le générique dans les Coutumes de Beauvaisis
Authors: Blumenthal Peter 
Published: April 2018

Our corpus, the original version of which was drawn up in 1280 or thereabouts, contains numerous 14th — and 15th — century manuscripts that help throw light on the variety of ways in which genericness is expressed and how these have tended to change over time.
The present paper examines the interplay of semantic, syntactic and pragmatic factors influencing the choice of the generic article. The polymorphism of these means of expression is matched by a certain heterogeneity where the signified is concerned : the generic appears in our texts in many different forms, prompting the modern reader to reflect on what analogies these offer with the categories of medieval thought.
Passé simple et spécificité
Authors: Hanon Suzanne 
Published: April 2018

Alors que certains temps grammaticaux peuvent être caractérisés comme non déictiques, comme le présent de l'indicatif, d'autres temps grammaticaux sont confinés dans des emplois et dans des sens extrême¬ ment spécifiques : c'est le cas du passé simple et du passé antérieur, du futur simple et du futur périphrastique.
La spécificité du passé simple peut s'exprimer dans les domaines suivants : (1) le contenu (aspect) ; (2) les emplois syntaxiques ; (3) les emplois lexicaux (Aktionsart ) ; (4) les registres (registre parlé, écrit, etc.) ; (5) les emplois stylistiques ; (6) les emplois modaux.
Ces emplois spécifiques font du passé simple un temps extrême¬ ment contraint. Le registre qui lui est propre est celui de Vénonciation historique, écrite, généralement associée à l'emploi de la 3e personne. On trouve cependant des registres mixtes, où discours et énonciation historique sont entremêlés. L'opposition nette proposée par É. Benveniste peut donc être remise en question.
La distinction valeur générique/valeur non spécifique est-elle soutenable ?
Authors: Karolak Stanislas 
Published: April 2018

The present article supports the combinatory (nonsemantic) distinction between the generic and nonspecific value of the indefinite noun phrase. The line of argument presented is the following : nonindividual concepts and terms taken out of context have a general value, which is their only inherent value, identical with their extension. Any other values associated with them appear in a given context, i.e. when they take on syntactic functions. The conclusion drawn is that these values are relational (combinatory). •
Two types of syntactic functions are distinguished : attributive function (attributive use) or constitutive propositional function, and referential function (referential use) or function of binding the argument variable in the scope of another term. Therefore, the referential use of a term is identical with its restrictive function.
The generic value of a general term is the result of its referential use (as the restrictor of an argument variable) in the scope of a general term, the latter being in attributive use. The nonspecific value of the same general term is generated by its attributive use. The only condition to be met is that the argument variable it has in its scope should be bound by a singular term incorporating a modal concept that excludes
Les synonymes syntaxiques de la langue française dans leur fonction sémantique et fonctionnelle [titre en russe]
Authors: Soatžonov Irgaš , Jakubov Žamolidin 
Published: April 2018

La synonymie syntaxique est un sujet qui suscite un vif intérêt parmi les linguistes. En effet, elle reflète la dynamique d'une langue, elle-même étroitement liée aux fonctions principales du langage : les fonctions nominative et communicative. La synonymie syntaxique est fort utile lors de l'apprentissage d'une langue étrangère. De fait, manier aisément une langue n'implique pas uniquement la connaissance de la grammaire et du lexique. Il faut aussi pouvoir exprimer un même contenu sémantique par divers équivalents syntaxiques, afin d'énoncer clairement ses pensées, de conférer à son discours toutes les nuances de la langue , de comprendre l'implicite, le non-dit.
Les auteurs de l'article se proposent d'analyser les différentes approches qui tentent de définir la synonymie syntaxique et de les analyser par des exemples concrets.
RETRACTED ARTICLE: Variable heart rate and a flexible mind: Higher resting-state heart rate variability predicts better task-switching

Published: April 2018

AbstractThe neurovisceral integration model proposes that heart rate variability (HRV) is linked to prefrontal cortex activity via the vagus nerve, which connects the heart and the brain. HRV, an index of cardiac vagal tone, has been found to predict performance on several cognitive control tasks that rely on the prefrontal cortex. However, the link between HRV and the core cognitive control function “shifting” between tasks and mental sets is under-investigated. Therefore, the present study tested the neurovisceral integration model by examining, in 90 participants, the relationship between vagally mediated resting-state HRV and performance in a task-switching paradigm that provides a relatively process-pure measure of cognitive flexibility. As predicted, participants with higher resting-state HRV (indexed both by time domain and frequency domain measures) showed smaller switch costs (i.e., greater flexibility) than individuals with lower resting-state HRV. Our findings support the neurovisceral integration model and indicate that higher levels of vagally mediated resting-state HRV promote cognitive flexibility.
Investigating the Metallicity–Mixing-length Relation

Abstract
Stellar models typically use the mixing-length approximation as a way to implement convection in a simplified manner. While conventionally the value of the mixing-length parameter, α, used is the solar-calibrated value, many studies have shown that other values of α are needed to properly model stars. This uncertainty in the value of the mixing-length parameter is a major source of error in stellar models and isochrones. Using asteroseismic data, we determine the value of the mixing-length parameter required to properly model a set of about 450 stars ranging in log g,

, and

. The relationship between the value of α required and the properties of the star is then investigated. For Eddington atmosphere, non-diffusion models, we find that the value of α can be approximated by a linear model, in the form of

. This process is repeated using a variety of model physics, as well as compared with previous studies and results from 3D convective simulations.
Why Are Some Galaxies Not Barred?
Authors: Saha Kanak , Elmegreen Bruce 
Published: April 2018

Abstract
Although more than two-thirds of star-forming disk galaxies in the local universe are barred, some galaxies remain unbarred, occupying the upper half of the Hubble tuning fork diagram. Numerical simulations almost always produce bars spontaneously, so it remains a challenge to understand how galaxies sometimes prevent bars from forming. Using a set of collisionless simulations, we first reproduce the common result that cold stellar disks surrounding a classical bulge become strongly unstable to non-axisymmetric perturbations, leading to the rapid formation of spiral structure and bars. However, our analyses show that galaxy models with compact classical bulges (whose average density is greater than or comparable to the disk density calculated within bulge half-mass radii) are able to prevent bar formation for at least 4 Gyr even when the stellar disk is maximal and having low Toomre Q. Such bar prevention is the result of several factors such as (a) a small inner Lindblad resonance with a high angular rate, which contaminates an incipient bar with x
2 orbits, and (b) rapid loss of angular momentum accompanied by a rapid heating in the center from initially strong bar and spiral instabilities in a low-Q disk; in other words, a rapid initial rise to a value larger than ∼5 of the ratio of the random energy to the rotational energy in the central region of the galaxy.

Abstract
Photoionization fronts play a dominant role in many astrophysical situations but remain difficult to achieve in a laboratory experiment. We present the results from a computational parameter study evaluating the feasibility of the photoionization experiment presented in the design paper by Drake et al. in which a photoionization front is generated in a nitrogen medium. The nitrogen gas density and the Planckian radiation temperature of the X-ray source define each simulation. Simulations modeled experiments in which the X-ray flux is generated by a laser-heated gold foil, suitable for experiments using many kJ of laser energy, and experiments in which the flux is generated by a “z-pinch” device, which implodes a cylindrical shell of conducting wires. The models are run using crash, our block-adaptive-mesh code for multimaterial radiation hydrodynamics. The radiative transfer model uses multigroup, flux-limited diffusion with 30 radiation groups. In addition, electron heat conduction is modeled using a single-group, flux-limited diffusion. In the theory, a photoionization front can exist only when the ratios of the electron recombination rate to the photoionization rate and the electron-impact ionization rate to the recombination rate lie in certain ranges. These ratios are computed for several ionization states of nitrogen. Photoionization fronts are found to exist for laser-driven models with moderate nitrogen densities (∼1021 cm−3) and radiation temperatures above 90 eV. For “z-pinch”-driven models, lower nitrogen densities are preferred (<1021 cm−3). We conclude that the proposed experiments are likely to generate photoionization fronts.
Life History of the Emerald Jewel Wasp Ampulex compressa
Authors: Arvidson Ryan , Landa Victor , Frankenberg Sarah , Adams Michael E. 
Published: April 2018

The Emerald Jewel Wasp Ampulexcompressa (Fabricius) is an endoparasitoid of the American cockroach Periplanetaamericana (Linnaeus). Its host subjugation strategy is unusual in that envenomation is directed into the host central nervous system, eliciting a long-term behavior modification termed hypokinesia, turning stung cockroaches into a lethargic and compliant, but not paralyzed, living food supply for wasp offspring. A.compressa manipulates hypokinesic cockroaches into a burrow, where it oviposits a single egg onto a mesothoracic leg, hatching three days later.
Herein we describe the life history and developmental timing of A.compressa. Using head capsule measurements and observations of mandibular morphology, we found that the larvae develop through three instars, the first two ectoparasitoid, and the third exclusively endoparasitoid. The first two instars have mandibles sufficient for piercing and cutting the cuticle respectively, while the third instar has a larger and blunter mandibular structure. During ecdysis to the third instar, the larva enters the body cavity of the cockroach, consuming internal tissues selectively, including fat body and skeletal muscle, but sparing the gut and Malpighian tubules. The developmental timing to pupation is similar between males and females, but cocoon volume and mass, and pupation duration are sexually dimorphic. Further, we show that the difference in cocoon mass and volume can be used to predict sex before eclosion, which is valuable for studies in venom pharmacology, as only females produce venom.
Raviver un souffle post-capitaliste
Authors: Citton Yves 
Published: April 2018

Après tant d’annonces de la fin prochaine, de l’effondrement ou du dépassement du capitalisme, comment et pourquoi y croire encore ? Peut-être convient-il de regarder ailleurs que là où l’on se tourne habituellement. Non pas seulement du côté de ses « ennemis », qui résistent bruyamment contre lui, mais tout autant en direction de cela même qui paraît aujourd’hui annoncer son triomphe : le numérique, l’information, l’automation, les métamorphoses du capital et l’hétérogénéité de ce qu’il rassemble. Les alternatives grouillent peut-être déjà sous l’apparence trompeuse d’une victoire de surface.

Rente, plèbe et corruption sont certainement « pré-capitalistes », emblématisant les ennemis archaïques que le nouvel ordre économique s’efforce depuis deux siècles d’éradiquer, pour leur substituer le « profit » (entrepreneurial), des « populations » (expertes) et « l’état de droit » (commercial). Mais rente, plèbe et corruption constituent aussi bien le présent de la gestion de l’information dans un monde socio-économique non dénué de « frictions », où des inégalités et des asymétries de plus en plus patentes échouent à entraîner l’adhésion de multitudes bien assez intelligentes pour ne pas croire au conte de fées de l’enfumage néolibéral.
Pediatric Eales Disease: An Indian Tertiary Eye Center Experience
Authors: Majumder Parthopratim Dutta , Sitaula Ranju Kharel , Biswas Jyotirmay 
Published: April 2018

Purpose:
To report the clinical profiles, etiologies, treatment modalities, and outcomes for Eales disease in patients younger than age 16 years in India.

Methods:
Retrospective review of medical records of patients with Eales disease who had a minimum 5-year follow-up period.

Results:
A total of 25 eyes of 13 patients were included. Of these 13 patients, 12 (94%) had bilateral Eales disease and 11 (84.6%) were men. Mean patient age was 14.1 years (range: 11 to 16 years). Diminution of vision (36%) was the most common presenting complaint, followed by both diminutions of vision and floaters (32%). Sclerosed vessels were seen in all eyes, and 21 (84%) eyes had active periphlebitis at presentation. Neovascularization elsewhere was seen in 20 (80%) eyes and neovascularization of the optic disc was seen in 1 (4%) eye. Veno-venous shunts were found in 12 (48%) eyes, and 18 (72%) eyes had vitreous hemorrhage. All eyes received photocoagulation; 84.6% of patients received oral steroids, with 7.7% of patients treated with azathioprine and 38.4% treated with anti-tubercular therapy. Vitrectomy was performed in 36% of eyes for non-clearing vitreous hemorrhage and tractional retinal detachment. Vision improved in 7 (28%) eyes, was stable in 12 (48%) eyes, and worsened in 6 (24%) eyes. Recurrence of the disease more than five times during the 5-year follow-up period occurred in 20% of patients.

Conclusions:
Recurrent vasculitis and vitreous hemorrhage in children should raise the suspicion of pediatric Eales disease.

Abstract
Type I IFN production of plasmacytoid dendritic cells (pDCs) triggered by TLR-signaling is an essential part of antiviral responses and autoimmune reactions. Although it was well-documented that members of the cytokine signaling (SOCS) family regulate TLR-signaling, the mechanism of how SOCS proteins regulate TLR7-mediated type I IFN production has not been elucidated yet. In this article, we show that TLR7 activation in human pDCs induced the expression of SOCS1 and SOCS3. SOCS1 and SOCS3 strongly suppressed TLR7-mediated type I IFN production. Furthermore, we demonstrated that SOCS1- and SOCS3-bound IFN regulatory factor 7, a pivotal transcription factor of the TLR7 pathway, through the SH2 domain to promote its proteasomal degradation by lysine 48-linked polyubiquitination. Together, our results demonstrate that SOCS1/3-mediated degradation of IFN regulatory factor 7 directly regulates TLR7 signaling and type I IFN production in pDCs. This mechanism might be targeted by therapeutic approaches to either enhance type I IFN production in antiviral treatment or decrease type I IFN production in the treatment of autoimmune diseases.

Abstract
Infiltration of neutrophils into colonic mucosa has been associated with the severity of ulcerative colitis (UC). We investigated the effect of disease microenvironment on the release of neutrophil extracellular traps (NETs) as well as the involved mechanisms in NETosis and whether certain NET proteins are correlated with disease phenotype. Peripheral blood neutrophils, sera, and colonic tissue were collected from treatment-naive and mesalazine-treated patients with active UC, treatment-naive patients with active Crohn’s disease, patients suffering from infectious colitis, or healthy individuals (controls). Analysis of colonic biopsy specimens and peripheral blood neutrophils for the presence of NET-related markers using immunofluorescence confocal microscopy, ELISA, immunoblotting, flow cytometry, and quantitative PCR were performed. In vitro cell and tissue culture systems were further deployed. The local inflammatory response in colon in UC, but not Crohn’s disease, is characterized by the presence of NETs carrying bioactive IL-1β and thrombogenic tissue factor. The inflammatory environment of UC is able to induce neutrophil activation, IL-1β expression, and NET release, as shown both ex vivo and in vitro. REDD1 expression, as a mediator linking inflammation, autophagy, and NET release, was also specifically associated with the inflammatory response of UC. We show that neutrophil expression of REDD1 in colon tissue and the presence of IL-1β in neutrophils/NETs provide candidate biomarkers for the differential diagnosis of inflammatory colitis and possible targets for the treatment of UC, suggesting that UC shares common features with autoinflammatory disorders.
