INTERACTIONS: DESIGN, IMPLEMENTATION AND EVALUATION OF A COMPUTATIONAL TOOL FOR TEACHING INTERMOLECULAR FORCES IN HIGHER EDUCATION

Intermolecular forces are a useful concept that can explain the attraction between particulate matter as well as numerous phenomena in our lives such as viscosity, solubility, drug interactions, and dyeing of fibers. However, studies show that students have difficulty understanding this important concept, which has led us to develop a free educational software in English and Portuguese. The software can be used interactively by teachers and students, thus facilitating better understanding. Professors and students, both graduate and undergraduate, were questioned about the software quality and its intuitiveness of use, facility of navigation, and pedagogical application using a Likert scale. The results led to the conclusion that the developed computer application can be characterized as an auxiliary tool to assist teachers in their lectures and students in their learning process of intermolecular forces.

Differentiation of Colletotrichum gloeosporioides isolates by using total proteins and esterase electrophoretic patterns and extracellular enzymes production

Isolates of Colletotrichum gloeosporioides (ISO-1, ISO-2, ISO-3, ISO-4, ISO-5 and ISO-6), the causal agent of anthracnose disease on mango fruits, were characterized by electrophoretic patterns of total proteins and esterase in polyacrylamida gel, and also, by production of extracellular enzymes on specific solid substrate. The electrophoretic analysis showed variation in number, intensity of coloration and position of the bands in the gel at each studied system tested. In contrast to the monomorphic behavior to total proteins, high esterase polymorfism was observed indicating difference among isolates. All isolates showed the activity of extracellular enzymes such as amylase, lipase, and protease with some variation among them. The proteolitic activity seemed to be more accentuated than the two other enzymes studied.

Negotiating home and belonging. Young Kurds in Finland

This study looks at negotiation of belonging and understandings of home among a generation of young Kurdish adults who were born in Iraq, Iran, and Turkey and who reached adulthood in Finland. The young Kurds taking part in the study belong to the generation of migrants who moved to Finland in their childhood and early teenage years from the region of Kurdistan and elsewhere in the Middle East, then grew to adulthood in Finland. In theoretical terms, the study draws broadly from three approaches: transnationalism, intersectionality, and narrativity. Transnationalism refers to individuals’ cross-border ties and interaction extending beyond nationstates’ borders. Young people of migrant background, it has been suggested, are raised in a transnational space that entails cross-border contacts, ties, and visits to the societies of departure. How identities and feelings of belonging become formed in relation to the transnational space is approached with an intersectional frame, for examination of individuals’ positionings in terms of their intersecting attributes of gender, age/generation, and ethnicity, among others. Focus on the narrative approach allows untangling how individuals make sense of their place in the social world and how they narrate their belonging in terms of various mechanisms of inclusion and exclusion, including institutional arrangements and discursive categorisation schemes. The empirical data for this qualitative study come from 25 semi-structured thematic interviews that were conducted with 23 young Kurdish adults living in Turku and Helsinki between 2009 and 2011. The interviewees were aged between 19 and 28 years at the time of interviewing. Interview themes involved topics such as school and working life, family relations and language-learning, political activism and citizenship, transnational ties and attachments, belonging and identification, and plans for the future and aspirations. Furthermore, data were collected from observations during political demonstrations and meetings, along with cultural get-togethers. The data were analysed via thematic analysis. The findings from the study suggest that young Kurds express a strong sense of ‘Kurdishness’ that is based partially on knowing the Kurdish language and is informed by a sense of cultural continuity in the diaspora setting. Collective Kurdish identity narratives, particularly related to the consciousness of being a marginalised ‘other’ in the context of the Middle East, are resonant in young interviewees’ narrations of ‘Kurdishness’. Thus, a sense of ‘Kurdishness’ is drawn from lived experiences indexed to a particular politico-historical context of the Kurdish diaspora movements but also from the current situation of Kurdish minorities in the Middle East. On the other hand, young Kurds construct a sense of belonging in terms of the discursive constructions of ‘Finnishness’ and ‘otherness’ in the Finnish context. The racialised boundaries of ‘Finnishness’ are echoed in young Kurds’ narrations and position them as the ‘other’ – namely, the ‘immigrant’, ‘refugee’, or ‘foreigner’ – on the basis of embodied signifiers (specifically, their darker complexions). This study also indicates that young Kurds navigate between gendered expectations and norms at home and outside the home environment. They negotiate their positionings through linguistic repertoires – for instance, through mastery of the Finnish language – and by adjusting their behaviour in light of the context. This suggests that young Kurds adopt various forms of agency to display and enact their belonging in a transnational diaspora space. Young Kurds’ narrations display both territorially-bounded and non-territorially-bounded elements with regard to the relationship between identity and locality. ‘Home’ is located in Finland, and the future and aspirations are planned in relation to it. In contrast, the region of Kurdistan is viewed as ‘homeland’ and as the place of origins and roots, where temporary stays and visits are a possibility. The emotional attachments are forged in relation to the country (Finland) and not so much relative to ‘Finnishness’, which the interviewees considered an exclusionary identity category. Furthermore, identification with one’s immediate place of residence (city) or, in some cases, with a religious identity as ‘Muslim’ provides a more flexible venue for identification than does identifying oneself with the (Finnish) nation.

Polyphenolic cells and their interrelation with cotyledon cells in seven species of Theobroma (Sterculiaceae)

The amount of cotyledon polyphenolic cells varies extensively within the Theobroma species. The polyphenolic compounds of these cells play a protective role and furthermore have an important function in the development of chocolate flavour. The morphology of the polyphenolic cells of the mesophyll is described and the development of these idioblasts in Theobroma cacao L., T. subincanum Mart., T. obovatum Klotzsch ex Bernoulli, T. grandiflorum (Willd. ex Spreng.) K. Schum., T. microcarpum Mart., T. bicolor Bonpl. and T. speciosum Willd. ex Spreng analysed. The total polyphenolic content in the seeds as determined by spectrophotometry showed a variation of about forty times. The alive, transparent polyphenolic cells are scattered throughout the cotiledonary mesophyll. However the polyphenolic cells of T. cacao and T. grandiflorum are also aligned perpendicularly with respect to the mesophyll borders and, in addition, both species display polyphenolic cells with a natural translucent purple colour. All the species analysed contained polyphenolic cells scattered throughout the parenchymal cells and also in a lengthwise association with vascular bundles. In T. bicolor and T. speciosum, the species with the lowest polyphenolic contents, these cells were mostly located around the vascular bundles. Using Scanning Electron Microscopy, the polyphenolic cells demonstrated a complex cytoarchitecture, and after fixing with glutaraldhyde, the polyphenolic secretion was shown to remain as a single unit or was organized into round droplets. Transmission Electron Microscopy displayed immature plastids from young mesophyll cells containing eletron-dense deposits similar to phenolic substances, suggesting that Theobroma plastids are involved in the synthesis of phenolics.

Chromosome number and secondary constriction variation in 51 accessions of a citrus germplasm bank

The mitotic chromosomes of 51 citrus accessions from the Centro Nacional de Pesquisa em Mandioca e Fruticultura Tropical, Cruz das Almas, BA, Brazil, were analyzed. The sample included representatives of 20 Citrus species, one of Poncirus and seven hybrids. All accessions showed 2n = 18 without any evidence of numerical variation. The most clearly variable karyotype feature was the number and position of secondary constrictions (SECs). In 19 accessions the SECs were not identified, mainly due to the degree of chromatin condensation. In the remainder they varied in number from one to three per karyotype. They were found in the proximal region of one of the three largest chromosome pairs, in the terminal/subterminal region of a smaller chromosome or, more seldom, terminally in a larger chromosome. Only in a few cases were such constrictions observed simultaneously in both homologues of the same chromosome pair. The high variability of this karyotype feature may be due to the activation of this region in the previous interphase but may also indicate a high structural variability and heterozygosity of citrus germplasms

Study of colossal magnetoresistance and pressure effects in La2/3Ca1/3MnO2 thin films /

The main purpose of this thesis is to study properties of La2/3Cai/3Mn03, both polycrystalline ceramics and thin films. This material has striking related electrical and magnetic properties. Thin films show colossal negative magnetoresistance (CMR) near transition from an insulating to a metallic state accompanied closely by transition from a paramagnetic to a ferromagnetic state. The double exchange mechanism (DE) and the Jahn-Teller deformations play an important role in CMR effect. Applied pressure has a very similar effect as does an applied magnetic field, except, at low temperatures (Tand magnetization measurements, as well as measurements of resistivity under applied pressure. The origin of strong resistivity change at low temperatures can be explcdned by the intergranular spin-dependent scattering of DE electrons. Oxygen stoichiometry plays an important role in the magnitude and position of MR(T) maximum. The distortions of structure and Mn-O-Mn bonds in applied pressure axe discussed. The fabrication of La2/3Cai/3Mn03 thin films by pulsed laser deposition was successfully developed. The films grown on (100) SrTiOs substrate are c-axis oriented and exhibit negative magnetoresistance Ap/p(H) of over 400% at 245°C and 4200% at 90 K.

Method and truth in MÄ dhyamika

Abstract The study was undertaken to identify what motivates registered nurses to participate in continuing education activities. The primary questions were whether basic nursing education, employment status, clinical area, and position, as well as readiness for selfdirected learning influenced Canadian nurses' motivational orientations when deciding to participate in continuing education activities. Other individual differences (e.g., age) were also examined. The sample included 142 registered nurses employed at an urban community hospital. Three instruments were used for data collection: the Education Participation Scale, the Self-Directed Learning Readiness Scale, and a nursing survey consisting of demographic questions. Basic nursing education and employment status did not effect motivational orientation or self-directed learning readiness. Clinical area and level of position significantly influenced nurses' decisions to participate in continuing education activities. Motivational orientation had a significant relationship with selfdirected learning readiness. Implications for practice as a result of this study involves program planning and delivery. The identification of the motivational orientations of participants may assist in the development and delivery of continuing education programs that are beneficial, relevant, and address the identified learning needs of participants. Implications for future research also exist in relation to studying different groups of nurses, for example, registered nursing assistants, and investigating related issues, for example, what are the deterrents to participation in continuing education?

Inuit ethnobotany and ethnoecology in Nunavik and Nunatsiavut, northeastern Canada

Les habitats uniques de l'écotone forêt boréale-subarctique dans le nord du Canada subissent les contrecoups du changement climatique. Combinés aux effets de la mondialisation, les changements environnementaux touchent les Inuits de cette région et imposent des contraintes importantes sur leur mode de vie traditionnel, ce qui a des répercussions sur leur langue et les savoirs qui l'accompagnent. Cette étude compare deux aspects de l’ethnobiologie inuite : a) les noms et les utilisations des plantes par les Inuits de Nain, Nunatsiavut, suivis par une comparaison des utilisations avec la communauté inuite de Kangiqsualujjuaq, Nunavik, et b) une analyse des types de lieux ou d’habitats que les Inuits reconnaissent et nomment. Des interviews semi-dirigés ont été menés à Nain, Nunatsiavut et à Kangiqsualujjuaq, au Nunavik. Les plantes mentionnées sont utilisées comme aliment, thé, médecine, combustible, construction, nettoyage, et autres utilisations. Les deux communautés ont utilisé un nombre égal de plantes, avec des proportions équivalentes de taxons vasculaires/invasculaires, de formes de croissance (habitus), et d’espèces par catégorie d'utilisation. Les éléments du paysage les plus fréquemment rapportés sont d’ordre topographique, hydrologique ou écologique. L’intégration des concepts inuits, quant aux plantes et au paysage, à ceux de la science occidentale peut améliorer notre compréhension de l'écologie subarctique, aider à impliquer les acteurs locaux dans les décisions sur le développement de leur territoire et, conséquemment, modifier l'aménagement du territoire ainsi que les initiatives de conservation de la biodiversité. Ces concepts ont également des répercussions sur les stratégies d'adaptation face aux changements climatiques.

Low Level Jet stream of Asian Summer Monsoon and its Variability

The main objective of the of present study are to study the intraseasonal variability of LLJ and its relation with convective heating of the atmosphere, to establish whether LLJ splits into two branches over the Arabian sea as widely believed, the role of horizonatal wind shear of LLJ in the episodes of intense rainfall events observed over the west coast of India, to perform atmospheric modeling work to test whether small (meso) scale vortices form during intense rainfall events along the west coast; and to study the relation between LLJ and monsoon depression genesis. The results of a study on the evolution of Low Level Jetstream (LLJ) prior to the formation of monsoon depressions are presented. A synoptic model of the temporal evolution of monsoon depression has been produced. There is a systematic temporal evolution of the field of deep convection strength and position of the LLJ axis leading to the genesis of monsoon depression. One of the significant outcomes of the present thesis is that the LLJ plays an important role in the intraseasonal and the interannual variability of Indian monsoon activity. Convection and rainfall are dependent mainly on the cyclonic vorticity in the boundary layer associated with LLJ. Monsoon depression genesis and the episodes of very heavy rainfall along the west coast of India are closely related to the cyclonic shear of the LLJ in the boundary layer and the associated deep convection. Case studies by a mesoscale numerical model (MM5) have shown that the heavy rainfall episodes along the west coast of India are associated with generation of mesoscale cyclonic vortices in the boundary layer.

Positioning an underwater vehicle through image mosaicking

Mosaics have been commonly used as visual maps for undersea exploration and navigation. The position and orientation of an underwater vehicle can be calculated by integrating the apparent motion of the images which form the mosaic. A feature-based mosaicking method is proposed in this paper. The creation of the mosaic is accomplished in four stages: feature selection and matching, detection of points describing the dominant motion, homography computation and mosaic construction. In this work we demonstrate that the use of color and textures as discriminative properties of the image can improve, to a large extent, the accuracy of the constructed mosaic. The system is able to provide 3D metric information concerning the vehicle motion using the knowledge of the intrinsic parameters of the camera while integrating the measurements of an ultrasonic sensor. The experimental results of real images have been tested on the GARBI underwater vehicle

Criminality and legitimization in seawaters: a study on the pirates of Malabar during the age of european commercial expansion (1500-1800)

The maritime piracy included a wide variety of associated criminal activities including attack and confiscation of vessels and merchandise, imprisonment or torturing of merchants and rulers in sea-space in return for ransom money, attack and raiding of coastal trading centers and villages, creation of fear and terror in chief channels of navigation and attacking commercial competitors as a strategy to weaken the trading ability and the wealth-mobilizing ability of their rivals. All this applied to coastal south west India during the period under study. The merchant chiefs of Cannanore like Mamale Marakkar and later under Poca Amame (Pokar Ahamad) and Pocarallee (Pokar Ali) were some of the better known protagonists that the Portuguese had to deal with. But the Malabar corsairs had their corresponding English and Sicilian corsairs in the Mediterranean.

The social relations of business representation and devolved governance in the United Kingdom

The reform of regional governance in the United Kingdom has been, in part, premised on the notion that regions provide new territories of action in which cooperative networks between business communities and state-agencies can be established. Promoting business interests is seen as one mechanism for enhancing the economic competitiveness and performance of 'laggard' regions. Yet, within this context of change, business agendas and capacities are often assumed to exist 'out there, as a resource waiting to be tapped by state institutions. There is little recognition that business organisations' involvement in networks of governance owes much to historical patterns and practices of business representation, to the types of activities that exist within the business sector, and to interpretations of their own role and position within wider policymaking and implementation networks. This paper, drawing on a study of business agendas in post-devolution Scotland, demonstrates that in practice business agendas are highly complex. Their formation in any particular place depends on the actions of reflexive agents, whose perspectives and capacities are shaped by the social, economic, and political contexts within which they are operating. As such, any understanding of business agendas needs to identify the social relations of business as a whole, rather than assuming away such complexities.

A link between low-frequency mesoscale eddy variability around Madagascar and the large-scale Indian Ocean variability

A connection is shown to exist between the mesoscale eddy activity around Madagascar and the large-scale interannual variability in the Indian Ocean. We use the combined TOPEX/Poseidon-ERS sea surface height (SSH) data for the period 1993–2003. The SSH-fields in the Mozambique Channel and east of Madagascar exhibit a significant interannual oscillation. This is related to the arrival of large-scale anomalies that propagate westward along 10°–15°S in response to the Indian Ocean dipole (IOD) events. Positive (negative) SSH anomalies associated to a positive (negative) IOD phase induce a shift in the intensity and position of the tropical and subtropical gyres. A weakening (strengthening) results in the intensity of the South Equatorial Current and its branches along east Madagascar. In addition, the flow through the narrows of the Mozambique Channel around 17°S increases (decreases) during periods of a stronger and northward (southward) extension of the subtropical (tropical) gyre. Interaction between the currents in the narrows and southward propagating eddies from the northern Channel leads to interannual variability in the eddy kinetic energy of the central Channel in phase with the one in the SSH-field.
