METODE INQUIRI DALAM MENINGKATKAN KONSEP BERPIKIR MAHASISWA PADA MATERI SISTEM BILANGAN REAL
Authors: Sudarsono Sudarsono
Published: February 2019

Fenomena pendidikan di Indonesia, selalu menghadapi kurikulum yang selalu berubah setiap periodenya, sehingga menuntut para pendidik untuk terus menggembangkan ide kreatif terkait cara penyampaian materi yang baik dan benar. Dari kurikulum yang ada sekarang ini, dapat dilihat tingginya ekspektasi pemerintah yang tertuang dalam kurikulum tersebut, berbanding terbalik dengan realita nyata yang ada dilapangan sejauh ini, dimana sekolah menengah dan sekolah tinggi-pun masih mengunakan metode lama yang ditengarai dapat menurunkan standar pendidikan. Hal ini dikarenakan ketidaktepatan pendidik dalam merancang dan melaksanakan pembelajaran menjadi salah satu faktor penyebab hasil belajar matematika menjadi rendah. Kesulitan peserta didik dalam mempelajari matematika di sekolah, disamping disebabkan oleh sifat abstrak matematika itu sendiri juga disinyalir disebabkan oleh pendidik yang kurang tepat dalam merancang dan melaksanakan pembelajaran matematika di kelas. Proses belajar mengajar seperti inilah yang tidak mendorong mahasiswa berpikir kritis dan berkreatifitas, hal ini tidak sesuai dengan hakikat pribadi mahasiswa sebagai subjek belajar yang lebih tinggi. Dengan dasar itu, pembelajaran mahasiswa harus membangun sendiri pengetahuan mereka melalui keterlibatan aktif dalam proses belajar mengajar, mahasiswa sebagai pusat kegiatan pembelajaran bukan dosen. Apalagi jika dikaitkan dengan era revolusi industri 4.0 dimana manusia dituntut berpikir kritis dengan memanfaatkan media dan teknologi terbarukan abad ini.

Pseudomonas aeruginosa a common opportunistic pathogen in Jordan: A review article.
Authors: Shehabi Asem A. , Kamal Aya M.
Published: February 2019

Pseudomonas aeruginosa is widely present in many diverse environments. It can be found in various living sources, including water, plants, intestinal tract of human and animals, and most importantly hospital environment. The organism is an important cause of nosocomial infections, such as septicemia and pneumonia, life-threatening infections in immunocompromised persons, and chronic infections in cystic fibrosis patients. Recent studies reported that hospitalized patients infected with multidrug resistance (MDR) P. aeruginosa have increased hospital length of stay and mortality. This short review focus on the current common occurrence and antimicrobial susceptibility pattern of P. aeruginosa in Jordan.

Le rejet de la maniera italienne : l’exemple des décors de Charles de La Fosse (1636-1716)
Authors: Weil-Curiel Moana
Published: February 2019

Charles de La Fosse, par la durée de sa carrière et par la diversité de ses commanditaires, nous est apparu comme un exemple particulièrement intéressant de la prise d’autonomie progressive des artistes français sur la pratique italienne du grand décor. La création en 1666 de l’Académie de France à Rome, qui les mettait au contact de certaines des plus belles réalisations romaines ou lombardes, constitua une étape particulièrement importante, tandis que l’aménagement des résidences royales, la construction ou la modernisation de nombreux hôtels parisiens et de résidences aristocratiques créaient autant d’opportunités de démontrer leurs talents. L’évocation des différents décors de Charles de La Fosse nous a permis de formuler un certain nombre d’hypothèses. Enfin, nous avons pu rappeler l’influence qu’il eut sur certains grands peintres (Watteau ou Lemoyne) quand, au début du xviiie siècle, l’amour-propre et le goût français rejettent, non sans nuances, la maniera italienne.
Deux tableaux retrouvés de Charles de La Fosse : Jésus et la Samaritaine et L’Adieu d’Hector et d’Andromaque
Authors: Devedjian Franck
Published: February 2019

Deux tableaux de Charles de La Fosse sont réapparus récemment sur le marché de l’art : Jésus et la Samaritaine, et L’Adieu d’Hector et d’Andromaque. L’étude détaillée de ces deux œuvres renseigne sur la riche culture visuelle du peintre. La Fosse prend soin de se référer avec attention aux sources anciennes et manie la règle du contraste pour mettre en valeur ses compositions. Élève de Le Brun, son goût de la couleur fait de lui le chef de file des coloristes. L’influence des grands maîtres qui l’ont précédé est sensible et la référence à l’œuvre de Rembrandt paraît déjà évidente dans Jésus et la Samaritaine, toile qui doit dater vers 1685-1688. Le deuxième tableau, L’Adieu d’Hector et d’Andromaque, d’un format plus imposant, a été présenté par Charles de La Fosse au Salon de 1699, l’année même où le peintre est nommé directeur de l’Académie royale de peinture et de sculpture. Cette toile connue, mais dont la localisation était restée ignorée, est une peinture importante dans laquelle l’artiste utilise une tonalité rougeoyante qui présage de la mort d’Hector et du futur incendie de Troie. Citant Charles Le Brun, comme les grands maîtres étrangers, Véronèse, Titien ou Rembrandt, le peintre y décrit, avec une grande finesse des sentiments, les adieux déchirants du héros troyen et de son épouse résignée. Comme si la douleur liée à tant de sang versé ne pouvait trouver sa rédemption que dans la célébration d’un amour éternel.
Jacques Rousseau et Charles de La Fosse chez le duc de Montagu à Londres
Authors: Bergeret Virginie
Published: February 2019

Lors de son séjour à Londres, dans les années 1690, Charles de La Fosse élabora une série de décors pour Lord Montagu dans sa demeure de Montagu House dans le quartier Bloomsbury. Il travailla alors en collaboration avec deux artistes, Jacques Rousseau et Jean-Baptiste Monnoyer. Les récentes recherches menées sur Jacques Rousseau, peintre à Versailles, à Marly et dans des hôtels particuliers parisiens, ont permis de montrer l’importance de cet artiste qui fut particulièrement actif et présent lors de la décoration de Montagu House. Sans minimiser le rôle de Charles de La Fosse, cet article présente l’histoire de sa collaboration avec Jacques Rousseau. Celui-ci eut en effet une riche carrière française avant d’arriver à Londres, ce qui l’amena probablement à croiser Charles de La Fosse sur différents chantiers. L’étude des décors disparus de Montagu House est l’occasion de revenir sur la place respective des deux artistes dans cette campagne.
Between Coloris and Dessein
Authors: Reyes Hector
Published: February 2019

Charles de La Fosse is associated with two defining, if opposed, poles of Academic theory and practice: the dessein camp associated with the practice and theory of Charles Le Brun; and the coloris camp, associated with the theory of Roger de Piles and the practice of Antoine Watteau. In this paper I will analyse La Fosse’s Assumption of the Virgin (Musée Magnin), looking specifically at its invocation of works by Poussin of the late 1620s and early 1630s. Rather than focusing on the differences between the dessein and the coloris camps, this paper will consider how the two theories might have found pictorial expression in the works of Poussin. I argue that La Fosse broadened the understanding of Poussin’s work beyond Le Brun’s theoretical framework. La Fosse’s work might be viewed as a practical intervention in theoretical debates, one that reconciled two seemingly opposed camps.
Jean-Baptiste Monnoyer (Lille, 1636-Londres, 1699) et le motif de la guirlande
Authors: Salvi Claudia
Published: February 2019

À travers trois moments clés du parcours de Jean-Baptiste Monnoyer (1636–1699), l’auteur cherche non seulement à mettre en lumière les différents types de collaboration entre le peintre de nature morte et de fleurs qu’il a été avec Charles de La Fosse (1636–1716), mais encore à montrer que le rapport de hiérarchie unilatérale qui semble caractériser les liens que les peintres d’histoire et de « genre » entretenaient entre eux n’est pas aussi pertinent qu’on l’a dit. Ainsi, par-delà le cas Charles de La Fosse, l’auteur montre comment Jean-Baptiste Monnoyer se révèle moins l’auxiliaire du peintre d’histoire que l’alter ego de celui-ci dans le genre qui est le sien.
Variations sur la galerie des Glaces pour le château de Choisy ?
Authors: Gady Bénédicte
Published: February 2019

Trente dessins très finis et relevés d’aquarelles par Charles de La Fosse conservés à Würzburg forment le puzzle d’un mystérieux décor plafonnant. Quatre feuilles de Michel II Corneille en donnent la clé : une copie d’après La Fosse en collection particulière, deux compartiments au British Museum et au Courtauld Institute, un projet d’ensemble au musée des Arts décoratifs. Elles suggèrent que les deux artistes ont répondu successivement à une même commande pour une galerie, dans la deuxième moitié des années 1680, permettent d’en restituer la structure et la disposition et d’en identifier les scènes. Dérivant de la galerie des Glaces, le décor exalte les victoires de Louis XIV pendant la guerre de Hollande, du Passage du Rhin au Traité de Nimègue. Des compartiments ovales louent les vertus et les missions du prince en s’inspirant du monnayage impérial. À Versailles comme ici, l’histoire du règne à travers le grand décor semble enrichir celle par les médailles et sa publication en 1702 par l’Académie des inscriptions et belles-lettres. La galerie de La Fosse et de Corneille mêle personnages réels, dieux mythologiques et figures allégoriques sans confondre les registres comme le fait Le Brun à la galerie des Glaces. Une annotation ancienne désigne le château de Choisy comme destination, ce que plans et échelles corroborent. Serait-ce une commande de la Grande Mademoiselle après sa rupture avec Lauzun et l’abandon consécutif du projet de galerie sur le thème de Vénus ?
Introduction
Authors: Sarrazin Béatrice
Published: February 2019

L’introduction souligne l’articulation entre l’exposition, « Charles de La Fosse (1636-1716) : le triomphe de la couleur », et le colloque « Charles de La Fosse et les arts en France autour de 1700 ». Cette première exposition monographique consacrée à l’artiste s’est tenue en 2015 au château de Versailles et au musée des beaux-arts de Nantes. Quarante peintures et une trentaine de dessins ainsi que les œuvres in situ, témoignages époustouflants de la verve créatrice du peintre, permettaient de montrer la richesse de sa carrière et la variété de son talent. En complément de l’exposition, le colloque fut l’occasion d’enrichir le corpus de l’artiste, de creuser des pistes, de cerner davantage son entourage et de lui redonner sa place dans les changements stylistiques de l’époque.
Conclusion : une génération La Fosse ? Nouveaux lieux et paradigmes de la peinture en France autour de 1700
Authors: Bonfait Olivier
Published: February 2019

S’appuyant sur les différentes publications concernant Charles de La Fosse et sur les communications du colloque « Charles de La Fosse et les arts en France autour de 1700 » qui s’est tenu les 18 et 19 mai 2015 au château de Versailles, l’article revient d’abord sur la difficulté à caractériser et à nommer les importants changements stylistiques qui se font jour entre 1680 et 1720. Il souligne ensuite l’émergence d’un nouveau lieu pour la peinture en France, la peinture de plafond, pour laquelle les solutions plastiques sont multiples et qui amène l’artiste à établir un rapport plus approfondi avec le commanditaire, comme le montre le cas de La Fosse. Enfin, l’article insiste sur la naissance d’un nouvel objet dans la France de la fin du xviie siècle, le tableau, qui est mieux mis en valeur dans les intérieurs et prend son autonomie, à la fois parce qu’il est le lieu de citations de la part des peintres (et donc de prise de conscience d’une histoire), et parce qu’il est le support de discours savants et de conversations mondaines.

In the study, the answers obtained from the interview form were themed and interpretations were made based on the results.Keywords: school experience, prospective teachers, teaching profession
How the Widespread Presence of Historical Private Real Estate Can Contribute to Local Development
Authors: Monti Luciano , Cerroni Roberto
Published: February 2019

For decades, historical assets have been considered, particularly real estate, as a heritage to be conserved, but limiting the use to museums. The concept of enterprise was considered far removed, if not an indication of the dangerous commodification of the aforementioned assets. On the one hand, the emergence of an ever-increasing demand for cultural services connected to this patrimony, and, on the other hand, the increasing difficulties in finding adequate resources for the conservation of the latter, have pushed a greater number of operators to take into consideration the instrument of cultural industry, the latter whose goal is to secure resources for the maintenance of the artistic historical patrimony by exploiting the potential of the same. Italy is an important test for this challenge, because it can count on an intense pool of historical and artistic heritage, that is unique and unrivalled in the world.

In this paper, therefore, we try to relate the investments necessary for the conservation and enhancement of the Italian private historical real estate assets, with the concentration of the aforementioned in certain realities and with the current local economic development of cultural and creative industries.

The cross analysis shows clearly how the enhancement of private real estate assets is particularly relevant in smaller cities and can represent a stimulus for a specific economic, social and cultural growth model.

However, this opportunity at the local level is unfortunately not always cultivated, therefore, we call for a comprehensive set of structural, long-term interventions in the sector, both at national and supranational level, for not only economic but social revival of private historical heritage.
A physiologically-based pharmacokinetic model of oseltamivir phosphate and its carboxylate metabolite for rats and humans
Authors: Gao Guanghua , Law Francis , Wong Ricky Ngok Shun , Mak Nai Ki , Yang Mildred Sze Ming
Published: February 2019

Oseltamivir phosphate (OP, Tamiflu®) is a widely used prodrug for the treatment of influenza viral infections. Orally administered OP is rapidly hydrolyzed by the carboxylesterases in animals to oseltamivir carboxylate (OC), a potent influenza virus neuraminidase inhibitor. The goals of this study were to develop and validate a physiologically-based pharmacokinetic (PBPK) model of OP/OC in rats and humans, and to predict the internal tissue doses for OP and OC in humans after receiving OP orally. To this end, a PBPK model of OP/OC was first developed in the rat, which was then scaled up to humans by replacing the physiological and biochemical parameters with human-specific values. The proposed PBPK model consisted of an OP and an OC sub-models each containing nine first-order, flow-limited tissue/organ compartments. OP metabolism to OC was assumed to carry out mainly by hepatic carboxylesterases although extra-hepatic metabolism also occurred especially in the plasma. The PBPK model was developed and validated by experimental data from our laboratories and from the literature. The proposed PBPK model accurately predicted the pharmacokinetic behavior of OP and OC in humans and rats after receiving a single or multiple doses of OP orally or an OC dose i.v. The PBPK model was used to predict the internal tissue doses of OP and OC in a hypothetical human after receiving the recommended dose of 75 mg/kg OP b.i.d. for 6 days. Steady-state OC concentrations in the plasma and major organs such as the lung and the brain were higher than the minimum in vitro IC50 reported for H1N1 influenza virus neuraminidase, confirming OP is an effective, anti-viral agent. OP side-effects in the gastrointestinal tract and brain of humans were explainable by the tissue doses found in these organs. The PBPK model provides a quantitative tool to evaluate the relationship between an externally applied dose of OP and the internal tissue doses in humans. As such the model can be used to adjust the dose regimens for adult patients in disease states e.g., renal failure and liver damage.
Physiologically based pharmacokinetic (PBPK) modeling and simulation in drug discovery and development

Physiologically based pharmacokinetic (PBPK) modeling is a mechanistic or physiology based mathematical modeling technique which integrates the knowledge from both drug-based properties including physiochemical and biopharmaceutical properties and system based or physiological properties to generate a model for predicting the absorption, distribution, metabolism and excretion (ADME) properties of a drug as well as pharmacokinetic behavior of a drug in preclinical species and humans.
Effects of Different Steeping Temperatures on the Leaching of Aroma Components in Black Tea by SPME–GC–MS Coupled with Chemometric Method
Authors: Wang Ziyan , Han Binsong , Jing Wangfang , Yi Zhibiao , Zhang Yi , Ren Dabing , Yi Lunzhao
Published: February 2019

Background: Black tea is famous for its unique aroma. The analysis of aroma components has attracted considerable attention worldwide because of its complex chemical composition and low concentration. Objective: Steeping temperature is one of the most important factors
affecting the aroma of black tea. This study aims to evaluate the effects of four steeping temperatures [60, 70, 80, and 95°C (boiling water)]. Methods: Two major factors affecting extraction performance, including the type of extraction method [direct headspace injection (HS) and
solid-phase microextraction (SPME)] and extraction time (50, 60, and 70 min), were optimized to enrich and analyze the aroma components of Congou black tea by GC–MS. In addition, heuristic evolving latent projection (HELP), an effective chemometric resolution method, was employed to
resolve the overlapped peaks. Results: A total of 83 aroma components were tentatively identified by GC–MS, such as alcohol (42.06–50.52%), aldehyde (12.09–15.97%), and hydrocarbon (4.79–15.32%). Linalool and its oxides (25.49–36.24%) were the most abundant
aroma components, followed by geraniol (2.55–8.54%), methyl salicylate (1.84–9.50%), and nerol (1.93–4.41%). Conclusions: The black tea steeped at 95°C smelled more pleasant with mild green, roast, and fruity aroma. Moreover, at 80°C, the tea had sweeter fragrance
with floral aroma, while steeping at 60 and 70°C resulted in more reinforced woody and fatty aroma. Highlights: A total of 83 aroma components of black tea were tentatively identified by SPME–GC–MS. The overlapped peaks were resolved by the HELP method. Aroma characteristics
of different steeping temperatures were revealed.
Lutein as an Ingredient in Pediatric Nutritionals
Authors: Long Amy C , Kuchan Matthew , Mackey Amy D
Published: February 2019

Lutein is a xanthophyll carotenoid that can be found in a variety of fruits and vegetables that may be limiting in the pediatric diet, which makes it an attractive nutrient for addition to supplemental nutritional products. Including lutein in the diet from a young age may provide protective benefits during a critical time of ocular and cognitive development. Lutein accumulation in eye and brain has led to research to better define the physiological role of this nutrient. Infants are exposed to lutein primarily through the consumption of breast milk or infant formulas containing lutein. The ingredient has been evaluated to be safe by many scientific and regulatory authorities for the addition to food, including formulated nutritional products. Nonhuman primates have been important in the investigation of the role dietary lutein in eye and brain function. Studies examining diets low or absent in lutein have revealed the impact on brain and eye function. Diets low in lutein may compromise neural tissues such as those found in the eye, which are susceptible to oxidation from blue wavelength light. No dietary recommendations have been established for lutein; however, several publications have highlighted the accumulating evidence that lutein provides long-term benefits when incorporated in adequate amounts in the diet.
The Pacifist Tradition and Pacifism as Transformative and Critical Theory
Authors: Fiala Andrew ,   Eastern Illinois University
Published: February 2019

Pacifism is often painted into a corner as an absolute rejection of all violence and war. Such a dogmatic and negative formulation of pacifism does leave us with pacifism as a morally problematic position. But pacifism is not best understood as a negative claim. Nor is pacifism best understood as a singular or monistic concept. Rather, there is a “pacifist tradition” that is grounded in an affirmative claim about the importance of nonviolence, love, community building, and peaceful conflict resolution. This more positive conception of pacifism aims to transform social and political life. When understood in this way, pacifism is a robust and useful critical social theory. This paper explores the philosophy of pacifism in an attempt to reconceptualize pacifism as a tradition of normative critical theory. The paper argues that pacifism ought to be understood on analogy with other critical theories—such as feminism; that pacifism should be understood in terms of the “pacifist tradition”—along lines familiar from interpretations of the “just war tradition”; and that pacifism should be seen as offering interesting themes and ideas that are worthy of philosophical attention.
Spray Formation and Structural Deformation During the Oblique Impact of a Flexible Plate on a Quiescent Water Surface
Authors: Wang An , Kim Hyun-Tae , Wong Kit Pan , Yu Miao , Kiger Kenneth T. , Duncan James H.
Published: February 2019

The oblique impact of a flexible and a nearly rigid plate on a quiescent water surface is studied experimentally. Both plates are 122 cm long by 38 cm wide and are mounted with a 5° upward pitch angle and a 10° lateral roll angle. The plates are attached to a dual-axis instrument carriage. The horizontal and vertical components of the carriage (plate) motion are driven by servo motors and controlled by a single computer-based feedback system, which is set with a single trajectory that is traversed for all impact speeds. The transient strain at multiple locations on the upper surface of the plate is measured with optical fiber Bragg grating sensors and the out-of-plane deformation is measured with a photographic method. A cinematic laser-induced fluorescence technique is used to measure the water spray generated during the impact. Two types of spray are observed and several aspects of the spray behavior are found to be noticeably affected by the deformation of the plate. The maximum deflection along the plate's upper long edge is found to increase almost linearly with impact velocity.

1. Introduction

In rough seas, planing boats moving at high speed frequently slam into the water surface. The slamming process involves large highly transient pressures and forces on the hull, rapid accelerations of the boat and the water, the generation of water spray, and significant structural responses. This phenomenon is difficult to study numerically and experimentally because of the large motions of the hull and the violent motions of the water free surface, including the formation of spray sheets and the structural responses coupled with the flow dynamics.

The problem of slamming (water entry) has received significant attention in the past. Many of the previous studies on this subject examine fundamental problems, such as the impact of a wedge or a flat plate on water surface. Some early theoretical studies on the water entry of a rigid wedge include, e.g., Von Karman (1929) and Wagner (1932). Wagner's model considers the water rising adjacent to the surface of a vertically moving wedge with small deadrise angle. This model was later extended to higher order (e.g., Oliver 2007) and other geometries (e.g., Howison et al. 1991). Based on Wagner's theory, Dobrovol'Skaya (1969) derived a similarity solution to the water entry of a wedge and the solution at small deadrise angles (down to 4°) was computed numerically by Zhao and Faltinsen (1993) using a nonlinear boundary element method. De Divitiis and de Socio (2002) studied the water entry of symmetric and asymmetric wedges. In their method, the flow field is represented by potential flow singularities whose intensities are determined as part of the solution. Moore et al. (2012) did a numerical study of normal and oblique water entry of a threedimensional rigid body with its bottom surface nearly parallel to the water surface.

A partial refining of the Erdős-Kelly regulation
Authors: Górska Joanna , Skupień Zdzisław
Published: February 2019

The aim of this note is to advance the refining of the Erdős-Kelly result on graphical inducing regularization. The operation of inducing regulation (on graphs or multigraphs) with prescribed maximum vertex degree is originated by D. König in 1916. As is shown by Chartrand and Lesniak in their textbook Graphs & Digraphs (1996), an iterated construction for graphs can result in a regularization with many new vertices. Erdős and Kelly have presented (1963, 1967) a simple and elegant numerical method of determining for any simple \(n\)-vertex graph \(G\) with maximum vertex degree \(\Delta\), the exact minimum number, say \(\theta =\theta(G)\), of new vertices in a \(\Delta\)-regular graph \(H\) which includes \(G\) as an induced subgraph. The number \(\theta(G)\), which we call the cost of regulation of \(G\), has been upper-bounded by the order of \(G\), the bound being attained for each \(n\ge4\), e.g. then the edge-deleted complete graph \(K_n-e\) has \(\theta=n\). For \(n\ge 4\), we present all factors of \(K_n\) with \(\theta=n\) and next \(\theta=n-1\). Therein in case \(\theta=n-1\) and \(n\) odd only, we show that a specific extra structure, non-matching, is required.

Remarks on global solutions to the initial-boundary value problem for quasilinear degenerate parabolic equations with a nonlinear source term
Authors: Nakao Mitsuhiro
Published: February 2019

We give an existence theorem of global solution to the initial-boundary value problem for \(u_{t}-\operatorname{div}\{\sigma(|\nabla u|^2)\nabla u\}=f(u)\) under some smallness conditions on the initial data, where \(\sigma (v^2)\) is a positive function of \(v^2\ne 0\) admitting the degeneracy property \(\sigma(0)=0\). We are interested in the case where \(\sigma(v^2)\) has no exponent \(m \geq 0\) such that \(\sigma(v^2) \geq k_0|v|^m , k_0 \gt 0\). A typical example is \(\sigma(v^2)=\operatorname{log}(1+v^2)\). \(f(u)\) is a function like \(f=|u|^{\alpha} u\). A decay estimate for \(\|\nabla u(t)\|_{\infty}\) is also given.
Metric dimension of Andrásfai graphs
Authors: Pejman S. Batool , Payrovi Shiroyeh , Behtoei Ali
Published: February 2019

A set \(W\subseteq V(G)\) is called a resolving set, if for each pair of distinct vertices \(u,v\in V(G)\) there exists \(t\in W\) such that \(d(u,t)\neq d(v,t)\), where \(d(x,y)\) is the distance between vertices \(x\) and \(y\). The cardinality of a minimum resolving set for \(G\) is called the metric dimension of \(G\) and is denoted by \(\dim_M(G)\). This parameter has many applications in different areas. The problem of finding metric dimension is NP-complete for general graphs but it is determined for trees and some other important families of graphs. In this paper, we determine the exact value of the metric dimension of Andrásfai graphs, their complements and \(And(k)\square P_n\). Also, we provide upper and lower bounds for \(dim_M(And(k)\square C_n)\).
The complexity of open k-monopolies in graphs for negative k
Authors: Peterin Iztok
Published: February 2019

Let \(G\) be a graph with vertex set \(V(G)\), \(\delta(G)\) minimum degree of \(G\) and \(k\in\left\{1-\left\lceil\frac{\delta(G)}{2}\right\rceil,\ldots ,\left\lfloor \frac{\delta(G)}{2}\right\rfloor\right\}\). Given a nonempty set \(M\subseteq V(G)\) a vertex \(v\) of \(G\) is said to be \(k\)-controlled by \(M\) if \(\delta_M(v)\ge\frac{\delta_{V(G)}(v)}{2}+k\) where \(\delta_M(v)\) represents the number of neighbors of \(v\) in \(M\). The set \(M\) is called an open \(k\)-monopoly for \(G\) if it \(k\)-controls every vertex \(v\) of \(G\). In this short note we prove that the problem of computing the minimum cardinality of an open \(k\)-monopoly in a graph for a negative integer \(k\) is NP-complete even restricted to chordal graphs.

Published: February 2019

Målet med denne artikkelen er å belyse kompetanseområder en yrkesfaglærer trenger for å undervise i brede yrkesfaglige utdanningsprogram med tidlig yrkesspesialisering i videregående skole i Norge. Det er bred enighet om de generelle overordnede kompetanseområdene en lærer trenger, men forsket lite på hvilken kompetanse som konkret kreves for å undervise i brede utdanningsprogram. Med ny tilbudsstruktur som innføres i 2020, stilles det tydeligere krav om tidlig yrkesspesialisering fra første året i videregående skole. Hensikten med studien var også å undersøke hvilke implikasjoner endrede krav til lærerkompetanse gir for innholdet i yrkesfaglærerutdanningen. Forskningsspørsmålene handlet om hvilken kompetanse studentene viste i sin pedagogiske praksis, og hvordan yrkesfaglærerutdanningen kan og bør styrkes. Empirigrunnlaget er hovedsakelig basert på kvalitative undersøkelser med metoder som spørreundersøkelser, intervju og skriftlig materiell fra dialogkonferanser og evalueringer med noen kvantitative elementer fra perioden 2014 - 2017. Resultatene viser at studenter og yrkesfaglærere trenger mer opplæring i praktiske ferdigheter tilpasset de ulike yrkene som inngår i brede utdanningsprogram. Behovet for helhetlig lærerkompetanse ble her fremhevet, mens den faglige substansen som inngår i felleselementene i brede utdanningsprogram, må styrkes for å ivareta tidlig yrkesspesialisering. Likedan må koherensen mellom pedagogikk og yrkesdidaktikk, og praksisfeltet styrkes ytterligere.

Published: February 2019

The reproductive behavior of two populations of Artemia is analyzed, one from San Quintín, Baja California, and the other from Yavaros, Sonora. In the interpopulation mating, altemating oviparous and ovoviviparous reproduction was observed, with the former dominating. In the San Quintín intrapopulation crossbreeding, 100% oviparous reproduction was observed. The intrapopulation fertility of Artemia from San Quintín was 75% and from Yavaros, 82.35%. In the interpopulation ♀Yav/♂SQ crossbreeding, fertility was 73.3%, and in the ♀SQ/♂Yav crossbreeding, 66%. It is concluded from these experiences that the population from San Quintín is Artemia franciscana, although some delay was observed in the mating time with the Yavaros population, which suggests the beginning of a specific differentiation.

In this study, the allozymic and genotypic variation of leucine-aminopeptidase (Lap-2) and phosphoglucomutase (Pgm) in Procambarus clarkii from Baja California is analyzed, under different thermic conditions. The repeated exposure of the organisms to the critica1 thermal maximum (CTMax) did not show a hardening response. However, there are differences in the allelic and genotypic frequencies of Lap-2 and Pgm among the organisms acclimated at 20 and 33°C and the field population. On the other hand, the frequencies of the heterozygote genotypes of Lap-2 and Pgm are higher in the final CTMax of 20 and 33°C compared to the field population. These results show a variation in the allozymic and genotypic frequencies which are determined by the effect of temperature on P. clarkii. Also observed is a selection in favor of the heterozygote organisms in the CTMax.

The analysis of the stomach contents of 500 dolphinfish Coryphaena hippurus is presented. The fish were caught from the shoreline to 25 miles off Cabo San Lucas, Baja California Sur, Mexico. Fifty-one prey were identifíed from the food items of the dolphinfish, which pertain to three categories: fishes, cephalopods and crustaceans and, according to the index of relative importance, represent 56.3%, 23.1% and 20.6%, respectively. Of the 51 prey, 18 represented 97%. Dosidicus gigas, Pleuroncodes planipes, Balistes polylepis. Cypselurus callopterus and Auxis spp. contributed 70% of the food supply. The dolphinfish is characterized as a top predator or a highly voracious organism with a wide trophic spectrum. Its food habits tend to be closely related to the epipelagic environment.

A field experiment was conducted at main agriculture research station, Raichur (Karnataka, India) during Kharif 2016 to enhance the yield of Bt cotton and improve the economy of farmers under the rainfed situation. The experiment was laid out in split plot design with three land configuration practices as main plots and four different combinations of an organic and inorganic source of nutrients as subplots replicated thrice. The results showed that, significantly higher seed cotton yield (2834 kg ha-1) were recorded with land configuration practice of Ridges and Furrow method in conjunction with application of 90:45:45 NPK kg ha-1 (50% N through organic) when compared to Broad Bed and Furrow method and Flat Bed methods and their respective combination with different source of nutrients. This trend was also reflected in dry matter accumulation in various plant parts (leaves, stem and reproductive organs). The combined effect of Ridges and Furrow method and application of 90:45:45 NPK kg ha-1 (50% N through organic) also resulted in recording higher gross (Rs.1,53,018 ha-1) and net returns (Rs.1,07,67 ha-1) when compared to other treatment combinations. Therefore it was concluded that, land configuration practice of Ridges and Furrow method in combination with the application of 90:45:45 NPK kg ha-1 (50% N through organic) was found to be the best option to realise higher seed cotton yield and more economical.

The study was conducted in Central Brahmaputra Valley and Upper Brahmaputra Valley Zone of Assam in India. The present study is an attempt to study the effect of mechanization on income and limiting factors of farm mechanization of the sample farms. Primary data of 240 sample farms by personal interview schedule method was used for examining the effect of farm mechanization on income along with limiting factors for mechanization adoption  . All data collected from sample farms pertains to the year 2014-15. Tabular, per cent analysis were done and results obtained from these analysis were summarized to examine the impact of farm mechanization on income . In case of Tractor Ownership Farm, Tractor Hired Farm, Power Tiller Ownership Farm, Power Tiller Hired Farm and Bullock Operated Farm gross return per cropped hectare were Rs.62916.24, Rs. 61370.31, Rs.62408.87, Rs. 56783.89 and Rs.34425.58, respectively. Family labour income and net income also had inverse relationship with farm size in each categories of mechanized and Bullock Operated Farm and exception in case of under Group III under Tractor Hired Farm. Family labour income and net income relative proportion of each mechanized farm was higher over Bullock Operated Farm. Net return were observed to be Rs. 33898.17, Rs.377.76, Rs. 33606.45, Rs.27831.05 and Rs. (-)12075.51 in Tractor Ownership Farm, Tractor Hired Farm, Power Tiller Ownership Farm, Power Tiller Hired Farm and Bullock Operated Farms, respectively. Family labour income and net income also had inverse relationship with farm size in each categories of mechanized and Bullock Operated Farm and exception in case of under Group III under Tractor Hired Farm. Family labour income and net income relative proportion of each mechanized farm was higher over Bullock Operated Farm. Hence it was observed that there was positive impact of farm mechanization on income. In case of Tractor Hired Farm net income was higher than Tractor Ownership Farm. Small and scattered land holding and inadequate sufficient funds to meet the initial cost of purchasing were the most serious problem faced by the farmers in the study area as out of total household 170 and 169 numbers of farmers found it most serious in case of small and scattered land holding and high initial cost to purchase the machineries respectively So, hence effort should be given to make available of the tractors amongst the farmers in the study area through establishment of Farm Machinery Banks for custom hiring along with development financing of second hand tractors for small farmers having operational holding less than 2 hectares should been given  to make economical use machineries amongst the small farmers in the study area.

Abiotic stresses extremely affect crop productivity and agro-morphological and biochemical properties of all Brassica species. Due to these stresses, yield of many important Brassica species decreases by disturbing their normal growth rate. In this review, we have highlighted the latest reports about the impact of different abiotic stresses on different growth stages and other morpho-physiological processes of important Brassica species such as canola/rapeseed (Brassica napus), Indian mustard (Brassica juncea), Brassica oleracea and Brassica rapa. Many researchers reported that abiotic stresses influence the important morpho-biochemical characteristics such as root and shoot length, shoot fresh and dry weight, proline and relative water contents, chlorophyll amount, antioxidant enzymes activity of important Brassica species. Cell injury also occurs by disturbance in normal oxidative processes due to these stresses. Against these stresses genetic modification have been described for the development of transgenic plant. The present study will be useful to identify the best abiotic stress tolerant Brassica genotypes for further genetic engineering program and crop improvement programs.

The adequate knowledge of the weather behavior is very important for the design and management of socioeconomical, environmental and sustainability human interests in the coasts and oceans.  In the present study an extreme value analysis of maximum significant waves recorded at a buoy located in the Pacific Ocean was carried out.  The analysis was carried out from two perspectives, by considering a Generalized Extreme Value (GEV) model with stationary distribution (i.e., the time variations are not accounted for), and by considering a non-stationary GEV model, which incorporates the monthly seasonality of maximum observed values in time increments; the maximum significant wave behavior was parameterized using harmonic functions for the distribution measures. Both approaches were compared for a single buoy. In the study a seasonality effect was found, which was also present at the Gulf of Mexico in previous studies, and which cannot be captured by a stationary model.
