This study aims to analyze the traditional Islamic practice of Nahdlatul Wathan (NW) in positioning and attaching the religious authority of Tuan Guru or Kyai, which is being challenged by the Salafi purification movement. This also determines the efforts needed to desacralize this authority by the Salafi elite who united by the perception that the sacredness of certain people, including Tuan Guru, is unknown in Islam, and even contradicts Islamic teachings with claims based on the salaf manhaj. Data collected was based on the phenomena from the ideological contestation at the elite level of the two religious groups that affect the pattern of religion and the internal interaction of religious people in Lombok. It was then analyzed using the contestation theory framework operationally formulated by Antje Winner. Based on empirical tendencies, the result showed that the desacralization of religious authority is not solely influenced by theological factors of religious understanding rather by the struggle for the religious authority of religious elites in the public sphere. This indicates the increase in the number of Salafi preachers who carry the purification theme in various mosques and Majlis Taklim, the higher the probability of seeing educational institutions as a new challenge for Tuan Guru to maintain religious authority. The implication is that there is social fragmentation and conflict involving sectarian sentiments of religious groups, where the contestation of religious elites contributes.

Abstract A simple fabrication of end-bonded contacts InAsSb NW (nanowire) array detector to weak light is demonstrated in this study. The detector is fabricated using InAsSb NW array grown by molecular beam epitaxy on GaAs substrate. The metal-induced gap states are induced by the end-bonded contact which suppresses the dark current at various temperatures. The existence of the interface dipole due to the interfacial gap states enhances the light excitation around the local field and thus upgrades the photoresponsivity and photodetectivity to the weak light. The light intensity of the infrared light source in this report is 14 nW/cm2 which is about 3 to 4 orders of magnitude less than the laser source. The responsivity of the detector has reached 28.57 A/W at room temperature with the light (945 nm) radiation, while the detectivity is 4.81 × 1011 cm·Hz1/2 W−1. Anomalous temperature-dependent performance emerges at the variable temperature experiments, and we discussed the detailed mechanism behind the nonlinear relationship between the photoresponse of the device and temperatures. Besides, the optoelectronic characteristics of the detector clarified that the light-trapping effect and photogating effect of the NWs can enhance the photoresponse to the weak light across ultraviolet to near-infrared. These results highlight the feasibility of the InAsSb NW array detector to the infrared weak light without a cooling system.

- Abstract
The molecular orientation in polymer fibers is investigated for the purpose of enhancing their optical properties through nanoscale control by nanowires mixed in electrospun solutions. A prototypical system, consisting of a conjugated polymer blended with polyvinylpyrrolidone, mixed with WO
3 nanowires, is analyzed. A critical strain rate of the electrospinning jet is determined by theoretical modeling at which point the polymer network undergoes a stretch transition in the fiber direction, resulting in a high molecular orientation that is partially retained after solidification. Nearing a nanowire boundary, local adsorption of the polymer and hydrodynamic drag further enhance the molecular orientation. These theoretical predictions are supported by polarized scanning near-field optical microscopy experiments, where the dichroic ratio of the light transmitted by the fiber provides evidence of increased orientation nearby nanowires. The addition of nanowires to enhance molecular alignment in polymer fibers might consequently enhance properties such as photoluminescence quantum yield, polarized emission, and tailored energy migration, exploitable in light-emitting photonic and optoelectronic devices and for sensing applications.

NEOLIBERALISM , *POSTHUMANISM , *LITERARY criticism , *ANTHROPOCENTRISM - Abstract
An ecopolitical thread runs throughout Zadie Smith's fiction and non-fiction, problematising the author's self-described 'sentimental humanism'. In this article, I reflect on Smith's narrative and essayistic treatment of animals in the context of insights drawn from the recent 'nonhuman turn' in critical theory and literary criticism. I argue that Smith's work exhibits a fidelity to the existence of nonhuman alterity at the limits of human experience. In her narrative and essays, Smith threads a needle between understanding the human's nonhuman origins and the inevitable self-referentiality of human signifying systems. I begin by examining how strategies of 'soft representation' across Smith's writing deconstruct everyday anthropocentrism; I then analyse how her 2012 novel NW depicts British neoliberal ideology entangling urban foxes in human anxieties about race and class; finally, I discuss this novel's search for potential solidarities among urban animals, human and nonhuman, who are marginalised under twenty-first-century neoliberal policies.

NW ,Zadie Smith ,point of view ,reflector ,metafiction ,Language and Literature - Abstract
While the post-colonial approach (Fernández Carbajal, 2016; López-Ropero, 2016) has dominated research on Zadie Smith’s postmodern work, NW (2013), there has been little to no stylistic analysis of the novel. The article aims to fill in this theoretical gap by examining the different modes of point of view, indicating how they are linguistically encoded. Using Leech and Short’s model of narratological aspects of viewpoint (2007), the stylistic features of the third-person narrator and the reflectors are revealed. The analysis seeks to demonstrate that the narrative style varies with each shift of perspective and that the voice of the narrator and the characters’ points of view are linguistically intertwined. The research points out the stylistic metamorphosis of the narrator who moves from mimetic storytelling to metafiction, alternating between the covert narrator who foregrounds the characters’ point of view and the overt one who constantly pinpoints the linguistic identity of the novel. The fusion of form and content becomes the storyline of this novel, where the differences between viewpoints of the narrating voices reflect the differences between their lives.

- Abstract
In this work, the gas sensing properties of a single ZnO nanowire (NW) are investigated, simultaneously in terms of photoluminescence (PL) and photocurrent (PC) response to NO
2 gas, with the purpose of giving new insights on the gas sensing mechanism of a single 1D ZnO nanostructure. A single ZnO NW sensing device was fabricated, characterized, and compared with a sample made of bundles of ZnO NWs. UV near-band-edge PL emission spectroscopy was carried out at room temperature and by lowering the temperature down to 77 K, which allows detection of resolved PL peaks related to different excitonic transition regions. Surface effects were observed in PL maps, considering different nano and microstructures. Electrical and optical measurements were acquired at the same time during the NO2 gas exposure, allowing for the comparison of PL and PC response times and signal recovery. During NO2 gas desorption, irreversible behavior in the surface-related and donor-acceptor pair (DAP) regions is interpreted as the effect of an initial transient when electronic transfer from the gas molecules to the bulk occurs through the ZnO NW surface which acts as a channel. To the best of our knowledge, this is the first work which investigates the simultaneous PL optical and PC electrical response signals of a single ZnO NW to gas exposure.- Published

The ascending trend of Moore's law has stretched to the horizon, where the prospects of carbon-based materials show the potential of replacing the silicon-based complementary metal-oxide semiconductor technology. These alternatives include nanowire transistors, carbon nanotube field-effect transistors, quantum-dot cellular automata, and graphene nanoribbon field-effect transistors (GNRFETs). This paper presents a review of the evolution of graphene, its fabrication process, and graphene-based field-effect transistor device structures. The diverse features of graphene as a material are derived from its structural, electronic, and thermal properties. A brief review of the techniques utilized for the fabrication of GNRFETs is mentioned in this paper. GNRFETs are based on excellent electrical properties that include strong ballistic transport, high current ratio, better compatibility with high K dielectrics, high electron mobility, reliability, scalability, and transconductance. GNRFET structures are reviewed for several aspects which include the I
on /Ioff ratio, subthreshold swing, oxide thickness, high K dielectrics, etc. that help to monitor the improvement in the performance of GNRFET devices. A comparison of the structures is presented to help researchers have a fair idea of the impact of modifications on device performance. The compact model used to simulate GNRFET-based devices is also included in this paper. GNRFET-based devices have several applications to offer in the current scenario. This paper also reports several applications of present GNRFET-based devices. [ABSTRACT FROM AUTHOR]- Published

Radiation, being invisible and odorless, has become a major concern in modern-day healthcare, mining, security, and nuclear applications that require professionals to work in environments involving radioactive materials, often with only elementary training. Furthermore, the scenario is worsened by the absence of a real-time, accumulative radiation dosimeter of small/wearable form factor that can provide direct digital output for long-term continuous monitoring. In this article, we present the first monolithically integrated CMOS wearable radiation dosimeter, consisting a floating-gate (FG) resistive sensor with a sensitivity of 14 $\Omega $ /rad, and a time-domain resistance-to-digital-converter (RDC) that functions as an 18-bit voltage-controlled oscillator (VCO)-based ADC, consuming 861 nJ for 10-ms active read time (which translates to 861-nW at 1 S/s), with 3.29-pJ/conversion step energy efficiency. The proposed time-based RDC exhibits programmable energy-resolution scalability by controlling the measurement time (unlike traditional voltage/current-mode ADCs) and achieves 6-bit better resolution than the state-of-the-art VCO-based ADCs at low frequency (conversion time ≈10 ms). The implemented integrated dosimeter achieves 8-bit better resolution, 7.5 $\times $ lower power, and 40 $\times $ better sensitivity (up to 10-mrad dose) than the current CMOS FG dosimeters.

DYNAMIC programming , *ALGORITHMS , *SEQUENCE alignment , *SEMIDEFINITE programming - Abstract
Although dynamic programming (DP) is an optimization approach used to solve a complex problem fast, the time required to solve it is still not efficient and grows polynomially with the size of the input. In this contribution, we improve the computation time of the dynamic programming based algorithms by proposing a novel technique, which is called "SDP: Segmented Dynamic programming". SDP finds the best way of splitting the compared sequences into segments and then applies the dynamic programming algorithm to each segment individually. This will reduce the computation time dramatically. SDP may be applied to any dynamic programming based algorithm to improve its computation time. As case studies, we apply the SDP technique on two different dynamic programming based algorithms; "Needleman–Wunsch (NW)", the widely used program for optimal sequence alignment, and the LCS algorithm, which finds the "Longest Common Subsequence" between two input strings. The results show that applying the SDP technique in conjunction with the DP based algorithms improves the computation time by up to 80% in comparison to the sole DP algorithms, but with small or ignorable degradation in comparing results. This degradation is controllable and it is based on the number of split segments as an input parameter. However, we compare our results with the well-known heuristic FASTA sequence alignment algorithm, "GGSEARCH". We show that our results are much closer to the optimal results than the "GGSEARCH" algorithm. The results are valid independent from the sequences length and their level of similarity. To show the functionality of our technique on the hardware and to verify the results, we implement it on the Xilinx Zynq-7000 FPGA. [ABSTRACT FROM AUTHOR]

The potential of using rice straw (RS) in combination with wood fibre in the production of medium density fibreboard was investigated. Nano‐wollastonite (NW) was added to some of the panels to determine if it would enhance the physical and mechanical properties. It was found that satisfactory composite boards could be made with the addition of 10% RS to the wood fibre. Furthermore, the mechanical and physical properties of the composite were enhanced when NW was added. [ABSTRACT FROM AUTHOR]

- Abstract
Der gennemgås grundlæggende teori for plastisk og elastisk opførsel i Selective Area Growth (SAG) nanowires (NWs), som er groet i en heterostruktur med uoverensstemmelse mellem gitterkonstanterne. Vi fokuserer på III/V NWs af InAs på en buffer af enten InGaAs eller GaAs, og gennemgår litteraturen for analytiske forsøg på at beskrive deres vækst og udvikling, særligt med henblik på plastiske urenheder såsom misfit dislocations (MDs). Disse forsøg er fænomenologiske og kvalitativt korrekte, men de viser sig at være svære at bruge til kvantitative forudsigelser omkring kritiske højder og egenskaber af SAG NWs. Fra dette udgangspunkt udvikles et omfattende simulationsapparat som bruger finite element method (FEM) til at simulere relaksering i SAG heterostrukturer. Vi præsenterer en nyskabende teknik for også at simulere MDs, som kan generaliseres til alle morfologier og sammensætninger, og som skaber et strain field vi kan bekræfte teoretisk. Vi forudsiger en række kritiske højder og konkluderer, at den optimale indførelse af MDs er en kollektiv indførelse af adskillige på samme tid., We review the phenomenon of misfit dislocations (MDs) in Selective Area Growth (SAG) nanowires (NWs) which have been grown as heterostructures with an epitaxial mismatch. We research current analytical attempts at describing their formation alongside growth stages, focusing on III/V NWs of InAs on InGaAs and GaAs buffers. These phenomenological and qualitative descriptions of dislocation formation are found unhelpful in quantitative predictions, specifically for critical dimensions and controlling the quality and properties of SAG NWs. From here we develop an extensive finite element method (FEM) framework to simulate strain energy within SAG heterostructures. We present a novel technique for simulating MDs, transferable to any morphology and composition, and yielding verifiable strain fields. We predict several critical heights and find the optimal formation of MDs to be a collective one.

We have designed and fabricated two perovskite-based photodetectors (PPDs) with 2D and 1D metal oxide carrier transport layers having the structure of ZnO thinfilm (TF)/CH 3 NH 3 PbI 3 /NiO TF (Device1) and ZnO nanowire (NW)/CH 3 NH 3 PbI 3 /NiO NW (Device2). Vertical and porous 1D carrier transport layers were fabricated using the advanced glancing angle deposition (GLAD) technique. The structure with 1D carrier transport layers in Device2 showed an enhanced optical absorption and emission as compared to 2D layered structure in Device1. The Device2 would enhance the responsivity (R λ) upto 134 times in UV (390 nm) and 1350 times in visible (450 nm) region as compared to Device1. Moreover, the maximum detectivity (D*) values of 3.43 × 1011 Jones and 3.53 × 1011 Jones were observed for Device2 and 0.343 × 1011 and 0.35 × 1010 Jones for Device1 in UV and visible regions respectively. In addition to that, the Device2 also showed an external quantum efficiency (EQE) of 3.2 × 103% and 2.9 × 103% in UV and visible regions respectively. Furthermore, the Device2 showed an ultrafast device response with rise time and fall times of 0.17 s and 0.13 s respectively. The 1D carrier transport layers in PPDs can be used as good candidate for future broadband photodetectors (PDs). • 1-dimensional (1D) over 2D carrier transport layers in perovskite photodetector. • A large R λ of 10.5 A/W and 10.8 A/W in UV and visible respectively using nanowire. • The nanowire based photodetector show a huge D* and a low NEP. • A maximum EQE of 3.2 × 103% using the NW based photodetector. • An ultra-fast device response in millisecond by the NW carrier transport layers.

This article seeks to demonstrate that Zadie Smith’s fourth novel, 'NW' (2012), deviates away from celebratory multiculturalism in Britain, interrogating the struggle between critical cosmopolitanism and melancholia in a twenty-first century urban environment. It will be argued that Smith’s limited geographical focus (on an area in which she was born and continues to reside) intimates that the social constructs of the family and local community are more conducive to developing cosmopolitan empathy and meaningful relations. Through an analysis of the ethical values of hospitality and openness, it will be suggested that 'NW' reflects a rise in transnational relations and the construction of a cultural model of cosmopolitan communication haunted by national identity and the difficulties of negotiating cultural diversity. The article will then conclude by examining how 'NW' exposes the racial inequalities and socio-economic disparities continuing to reside at the heart of British urban life.

A simple and low-cost fabrication of end-bonded contacts InAsSb NW (nanowire) array detector to weak light is demonstrated in this study. The detector is fabricated using InAsSb NW array grown by molecular beam epitaxy on GaAs substrate. The MIGS (metal-induced gap states) is induced by the end-bonded contact which suppresses the dark current at various temperatures. The existence of the interface dipole due to the interfacial gap states enhances the light excitation around the local field, thus upgrade the photo responsivity and photo detectivity to the weak light. The light intensity of the infrared light source in this report is 14 nW/cm2 which is about 3 to 4 orders of magnitude less than the laser source. The responsivity of the detector has reached 28.57 A/W at room temperature with the light (945 nm) radiation, while the detectivity is 4.81×1011 cm·Hz1/2 W−1. Anomalous temperature-dependent performance emerges at the variable temperature experiments, and we discussed the detailed mechanism behind the non-linear relationship between the photoresponse of the device and temperatures. Besides, the optoelectronic characteristics of the detector clarified that the light trapping effect and photogating effect of the NWs can enhance the photoresponse to the weak light across ultraviolet to near-infrared. These results highlight the feasibility of the InAsSb NW array detector to the infrared weak light without a cooling system.

Black British ,Transmodern ,Identity ,Swingtime ,NW ,Zadie Smith ,Multiculturalism - Abstract
Zadie Smith is a prolific and challenging author, as her novels linger and make one question what one has consumed long after the reading has finished. This is one of the reasons that her debut novel, White Teeth, is still read and considered by scholars. Yet, Smith’s work has evolved alongside, and along with, the times and her readers. The championing of cosmopolitanism by early critics has been challenged not only in recent scholarship on those early novels, but by Smith’s later work as well. Multicultural identities are not as utopic as some would have us believe, but Smith’s characters rarely settle so neatly into boxes, they are complex, defy expectations, and challenge notions of propriety, sense, and decorum. While that first novel arguably comes in the early wake of postmodernism, her later novels, novellas, and non-fictional works look past this mode to what follows – the complicated grounds of how to construct identity in a world without fixed structures, or at least with those structures underground and thus more difficult to see, critique or combat. A transmodern construction of identity, as I have argued elsewhere, is built upon the notions of postmodern identity (in which epistemological and ontological markers are eroded) to construct a new formation – however with acknowledgement that choices are constrained, not completely free. As Smith notes in Feel Free, “recognising the reality of other people – and having them recognise the reality of you – is at the heart of the matter” which can be articulated as a positive transcultural encounter, but also maps onto the construction of a transmodern identity. Through an exploration of NW, Swingtime, and The Embassy of Cambodia, the essay elucidates the use of modernisms and postmodernism in understanding how the characters construct their identities, and considers the idea of a transmodern formulation of identity as a by-product of this potential intersection. The backgrounds of the protagonists, the focus on various class, racial and ethnic backgrounds, and geographic migrations all point towards a diversity of experience that modernism and postmodernism do not specifically address in their formulations, and the question becomes whether a construction of transmodernism might be able to account for that lack. This essay seeks to open up Smith’s later work for this kind of analysis, and see how it speaks to the transmodern paradigm of our contemporary world.

SOCIAL classes in literature ,ECONOMIC status in literature ,RACE awareness in literature - Abstract
NW by Zadie Smith opens with a multicultural and multiracial scene and revolves around the crises in the lives of four people with longstanding connection to Northwest London. The Northwest London in NW is a besieged city, and the people therein could not see any possibility of getting out because the gate has been latched with the concept of social class. In NW, the social class is materialized as space, economic position and race. Geographically NW features the main areas of London, and considers the role of that city in shaping the consciousness of the major characters, a partly spatial configuring of identity. In addition, the major characters in NW also suffer from occupational exclusion and economic exploitation, which then lead to their lower-class position since social class is constructed in such a way that agents are distributed according to their positions in the statistical distribution based on the economic and cultural capital. Finally the racial discrimination encountered by the characters in NW shows that class relations shape the form that racial oppression takes. The racialization of class issues becomes a politically effective tool for the wealthy to divide and rule the lower classes. In NW, Smith thus has adopted a more political attitude than in her previous books, so the relatively new perspective of her fiction might be the attention she draws to the persistent obstacles to class crossing and the acknowledgment of the rigid lines that still define the social classes.

NOVELISTS - Abstract
This article traces Zadie Smith’s recurring, but shifting, engagement with North London in her worksWhite Teeth,The Autograph Man,On Beauty,NWandThe Embassy of Cambodia. It argues that underlying Smith’s changing aesthetic approaches to this particular space is an ethical agenda: an emphasis on the necessity to engage critically and responsibly with space (which Doreen Massey has read as a social construction that impacts powerfully on individuals and groups). After a consideration of the different approaches to, and functions of, North London in Smith’s first three novels, it focuses on her structural and metanarrative engagement with space in her more recent works. This gives way to reflections on agency, in light of the social determination of concrete spaces. Whereas Smith set out to create inWhite Teetha representation of a quintessentially British space, it is what Massey refers to as a “global sense of space” – one that shapes national discourses – that manifests itself in her more recent literary North London.

This paper proposes to examine Zadie Smith’s NW (2012) in the light of her essay ‘Two Directions for the Novel’, in which she explores two roads for novel writing: ‘lyrical realism’ and ‘constructive deconstruction’. In NW, Smith uses a range of narrative techniques that are indebted to realist, modernist and postmodernist traditions, and by analysing some of them, this paper aims to find out where Smith situates herself on the literary map in 2012, how she deals with the legacies of the past and what new lines she may be drawing for herself. More than forty years after David Lodge’s essay ‘The Novelist at the Crossroads’, one may wonder whether Smith finds herself at an ‘anxiety crossroads’, to quote her own expression. Her mixture of stream-of-consciousness technique, straightforward narrative and metafictional devices shows that she chooses neither the highway of the well-made novel nor the side road of downright deconstruction, but embraces several directions without trying to reconcile them.

The gastro-intestinal (GI) tract is a very important part of the human digestive system but remains largely inaccessible for unobtrusive monitoring. Ingestible electronic devices are a very interesting concept to address this need. This paper discusses the current state of ingestible electronic devices and explores the potential they hold to provide unprecedented insight by measuring several aspects of the complex bio-chemical processes that happen in the GI tract in real-time. This will require novel sensor technology capable of measuring relevant markers with adequate specificity and accuracy. In order to be able to scale this functionality down to a form factor of an easily digestible pill, ultra-low-power wireless interface electronics are needed. This poses certain challenges and innovation opportunities related to sensing, wireless communication and powering to enable the next generation of ingestible electronic devices. [2020-0164]

Understanding and management of light is of great importance for nanoscale devices. This report demonstrates enhanced absorption, photoluminescence and scattering in InP nanowires when coated with dielectric polymer shell. The shells increase absorption and emission by a factor of ~2 and photoluminescence by a factor of ~4. A thorough optical characterization is provided, including reflectance, transmission, luminescence and scattering to incident and transmitted directions. From this characterization, we derive the distribution of absorbed light within the structure (InP nanowires, Au seed particles and the substrate). Additionally, reflectance, transmission and emission are shown to become increasingly diffuse with the dielectric shells. The results are thought to provide better understanding in light-matter interaction in nanostructures, as well as to provide valuable tools for light and scattering management in nanoscale optoelectronics.

- Abstract
Evidence of Cenozoic magmatism is found along the length of New Guinea. However, the petrogenetic and tectonic setting for this magmatism is poorly understood. This study presents new field, petrographic, U-Pb zircon, and geochemical data from NW New Guinea. These data have been used to identify six units of Cenozoic igneous rocks which record episodes of magmatism during the Oligocene, Miocene, and Pliocene. These episodes occurred in response to the ongoing interaction between the Australian and Philippine Sea plates. During the Eocene, the Australian Plate began to obliquely subduct beneath the Philippine Sea Plate forming the Philippine-Caroline Arc. Magmatism in this arc is recorded in the Dore, Mandi, and Arfak volcanics of NW New Guinea where calc-alkaline and tholeiitic rocks formed within subduction-related fore-arc and extension-related back-arc settings from 32 to 27 Ma. Collision along this plate boundary in the Oligocene-Miocene jammed the subduction zone and caused a reversal in subduction polarity from north-dipping to south-dipping. Following this, subduction of the Philippine Sea Plate beneath the Australian Plate produced magmatism throughout western New Guinea. In NW New Guinea this is recorded by the middle Miocene (18-12 Ma) Moon Volcanics, which include an early period of high-K to shoshonitic igneous activity. These earlier magmatic rocks are associated with the subduction zone polarity reversal and an initially steeply dipping slab. The magmatic products later changed to more calc-alkaline compositions and were emplaced as volcanic rocks in the fore-arc section of a primitive continental arc. Finally, following terminal arc-continent collision in the late Miocene-Pliocene, mantle derived magmas (including the Berangan Andesite) migrated up large strike-slip faults becoming crustally contaminated prior to their eruption during the Plio-Pleistocene. This study of the Cenozoic magmatic history of NW New Guinea provides new data and insights into

Polymethyl methacrylate (PMMA) polymer chains were grafted on neoprene W (NW) by a one-step ATRP reaction. The thermal properties of the products were analyzed by DSC. Improvement ofTgwas a result of the PMMA grafted chains. Also, the melting point (Tm) changed from 42°C for NW to 142°C for modified NW. Using different solvents for the resulting copolymers, aggregates were obtained. Phase separation was influenced by the grafting degree of PMMA and the employed solvent. The copolymers were analyzed by GPC, FT-IR, DSC, and SEM. [ABSTRACT FROM AUTHOR]

Molecular dynamics (MD) and modified analytical embedded atom method (MAEAM) are used to study the effect of the cross-sectional shape on the nanowire (NW) premelting. The results indicate that the premelting phenomenon occurs far below the melting point. The temperature dependence of mean square displacement (MSD) shows that the shape effect on the premelting phenomenon is obvious. Based on the detailed analysis of the atomic configuration, the premelting activation energy (PAE), and the shape factor, we have further found that the cross-sectional shape has an important effect on the premelting mechanism of the NW.

Abstract: The flexural vibrations of cracked micro- and nanobeams in the presence of surface effects are studied. The cracked-beam model is set up by dividing the classical cracked beam element into two segments connected by a rotational spring located at the cracked section. This model promotes a discontinuity in bending slope, which is proportional to the second derivative of the displacements. Numerical examples demonstrate the effects of beam length, and crack position and severity on the calculated values of natural frequencies of an anodic alumina nanowire in the presence of surface effects. Limiting cases are considered and good agreements with the data available in the literature are obtained. [Copyright &y& Elsevier]

International audience; The Rhone river represents the most important source of freshwater, nutrients and organic matter to the northwestern (NW) Mediterranean Sea and riverine input markedly affects biogeochemistry and ecosystem functioning in the estuarine and coastal zone. Structures of low salinity waters (LSW) originating near the river plume can also be transported along the continental shelf and offshore. The objective of the present study was to investigate the influence of LSW distant from their source, focusing on dissolved organic matter (DOM) and related microbial processes during two annual cycles (2007 and 2008) at a time series site characterized by the regular occurrence of LSW in spring (Microbial Observatory Laboratoire Arago). We observed enhanced bacterial heterotrophic production and community respiration and specific DOM features within these LSW, concurrently with low net community production. Our results suggest that LSW represent a mechanism of labile DOM supply, thereby sustaining enhanced heterotrophic microbial metabolism.

Identifying nursery habitats is of paramount importance to define proper management and conservation strategies for flatfish species. Flatfish nursery studies usually report upon habitat occupation, but few attempted to quantify the importance of those habitats to larvae development. The reliance of two sympatric flatfish species larvae, the European flounder Platichthys flesus and the common sole Solea solea, on the estuarine food web (benthic versus pelagic), was determined through carbon and nitrogen stable isotope analysis. The organic matter sources supporting the production of P.flesus and S.solea larvae biomass originates chiefly in the benthic food web. However, these species have significantly different C-13 and N-15 values which suggest that they prey on organisms that use a different mixture of sources or assimilate different components from similar OM pools (or both).

The article discusses a number of post-millennial London narratives in print and on screen. Significantly, these use chance as a structural device, contrive chance encounters between disparate characters and/or twists of fate in individual characters' lives. It is concerned with the changing fortunes of different areas of the metropolis by way of economic and cultural capital, migration within and beyond London, immigration and shifts in generic representations of the city. Chance here designates lucky, improbable, arbitrary and coincidental occurrences: modern inflections of a mythologised metropolitan theme.

A high-performance short-channel tri-gated polycrystalline-silicon nanowire (NW) field-effect transistor is developed by using simple sidewall spacer and lateral etching techniques without employing costly lithographic tools. Channel length of 120 nm and NW thickness of 25 nm can be easily formed by the self-aligned process. The device exhibits superior electrical characteristics because of the strong gate controllability: a subthreshold swing of 102 mV/dec, drain induced barrier lowing of 74.4 mV/V, and extremely high ION/IOFF ratio of 4.4 ×108(Vd=1 V) are obtained.

A new concept of vertical gallium nitride (GaN) Schottky barrier diode based on nanowire (NW) structures and the principle of dielectric REduced SURface Field (RESURF) is proposed in this paper. High-threading dislocation density in GaN epitaxy grown on foreign substrates has hindered the development and commercialization of vertical GaN power devices. The proposed NW structure, previously explored for LEDs offers an opportunity to reduce defect density and fabricate low cost vertical GaN power devices on silicon (Si) substrates. In this paper, we investigate the static characteristics of high-voltage GaN NW Schottky diodes using 3-D TCAD device simulation. The NW architecture theoretically achieves blocking voltages upward of 700 V with very low specific on-resistance. Two different methods of device fabrication are discussed. Preliminary experimental results are reported on device samples fabricated using one of the proposed methods. The fabricated Schottky diodes exhibit a breakdown voltage of around 100 V and no signs of current collapse. Although more work is needed to further explore the nano-GaN concept, the preliminary results indicate that superior tradeoff between the breakdown voltage and specific on-resistance can be achieved, all on a vertical architecture and a foreign substrate. The proposed NW approach has the potential to deliver low cost reliable GaN power devices, circumventing the limitations of today's high electron mobility transistors (HEMTs) technology and vertical GaN on GaN devices.

This study attempts to characterize the nature of seismicity, anisotropy and coherency of deformation in the crust and upper mantle beneath the Doda- Kisthwar region (DKR), Jammu, located in the Kashmir seismic gap of NW Himalaya. Location of earthquakes using local waveforms, and shear wave splitting in local and teleseismic waveforms recorded at 5 temporary stations, are performed for this purpose. The relocation of 890 earthquakes reveals two clusters along the NE and SW part (referred to as Kisthwar and Doda cluster respectively), which is attributed to the under-thrusting of the Indian plate and uplifting of Kisthwar Window respectively. The shear wave splitting analysis yielded a total of 47 local S and 11 XK(K)S splitting measurements. The corresponding Fast Polarization Azimuths (FPAs) show two distinct spatial patterns. In the first pattern, the FPAs are oriented along the NW direction, are perpendicular to the maximum horizontal stress, and are parallel to the structural trend as a result of oblique compression in the NW Himalaya. In the second pattern, the FPAs are oriented along the ENE-WSW direction and the corresponding delay times are found to be larger than those in the DKR. This could be because of localized deformation; the strike of fluid-filled fractures in the fault zone is also along the ENE-WSW direction, parallel to the course of the Chenab river. Thus, for both the trends, structure-induced anisotropy seems to be the most possible cause for the observed anisotropy. Further, the splitting parameters show a slight variation with depth for the respective orientation patterns. The delay times of the XK(K)S phases vary from 0.3 to 1.3 s, and cluster around 0.5 s, with the majority of FPAs, oriented along the ENE-WSW direction. This can be reconciled in terms of a combined effect of absolute plate motion (APM) related strain and finite strain induced by compression. The inconsistency in the upper crust and upper mantle anisotropy does not favour a coherently distributed lithospheric deformation in this segment of the NW Himalaya. The source of anisotropy in the upper crust is complex compared to that in the upper mantle. • Analysed the local S and XK(K)S phases to examine the coherency of deformation in the crust and upper mantle • The fast axis of anisotropy in the upper crust does not correlate with the regional stress pattern. • The anisotropy in the upper mantle is due to the combined effect of basal shear and extension induced by collision. • Lack of coherent deformation in the crust and upper mantle suggests a decoupled nature.

Aim: This paper reflects on the language and translation challenges faced and interventions used whilst undertaking cross-cultural public health research in Nepal using translators.\ud \ud Background: The growth in cross-cultural studies and international research highlights the use of translators and the associated challenges for researchers with regard to cultural and linguistic issues when collecting data in one language and analysing and reporting in another. The specific challenges when using translators are frequently overlooked in the research literature and translators and the interpretation processes omitted from the research methodology and/or discussion.\ud \ud Methods: The experiences and challenges for an English-speaking nurse researcher working with a team of translators in a cross-cultural study on the sexual and reproductive health (SRH) of young people in Nepal, in 2006, is explored in this paper. The paper employs a case study approach.\ud \ud The Study: Data were collected over four weeks observing the settings, and the SRH knowledge and practices of participants in two villages in Kathmandu Valley were identified using a questionnaire, which was administered as a structured interview, and from the nurse researcher's field notes. This provided information on the translation and interpretation events. Stages in the research process where error could occur are identified in the researchers model and the interventions taken to minimise these are discussed which clarify perspectives and opinions when researching in the field.\ud \ud Findings and Conclusion: Reflecting on translation and interpretation challenges during the data collection process in a language which the nurse researcher does not speak, can help reduce (or avoid) potential mistakes and error. The paper reflects on a model of translation processes which emerged during fieldwork which helps understand what events happened and what actions were taken to obtain the most accurate data. Using a model such as this for cross cultural fieldwork may be useful for both novice and established researchers.

Elite groups are interesting as they frequently are powerful (in terms of position, knowledge and influence) and enjoy considerable authority. It is important, therefore, to involve them in research concerned with understanding social contexts and processes. This is particularly pertinent in healthcare, where considerable strategic development and change are features of everyday practice that may be guided or perceived as being guided, by elites. This paper evolved from a study investigating the availability and role of nurses whose remit involved leading nursing research and development within acute NHS Trusts in two health regions in Southern England. The study design included telephone interviews with Directors of Nursing Services during which time the researchers engaged in a reflective analysis of their experiences of conducting research with an `elite' group. Important issues identified were the role of gatekeepers, engagement with elites and the use of the telephone interview method in this context. The paper examines these issues and makes a case for involving executive nurses in further research. The paper also offers strategies to help researchers design and implement telephone interview studies successfully to maximise access to the views and experiences of `hard to reach groups', such as elites, while minimising the associated disruption.

We propose operational method with recourse to generalized forms of orthogonal polynomials for solution of a variety of differential equations of mathematical physics. Operational definitions of generalized families of orthogonal polynomials are used in this context. Integral transforms and the operational exponent together with some special functions are also employed in the solutions. The examples of solution of physical problems, related to such problems as the heat propagation in various models, evolutional processes, Black–Scholes-like equations etc. are demonstrated by the operational technique.

Patterns and frequency of anxiety in women undergoing gynaecological surgery\ud Aims. Within a gynaecological surgical setting to identify the patterns and frequency\ud of anxiety pre- and postoperatively; to identify any correlation between raised\ud anxiety levels and postoperative pain; to identify events, from the patients’ perspective,\ud that may increase or decrease anxiety in the pre- and postoperative periods.\ud Background. It is well documented that surgery is associated with increased anxiety,\ud which has an adverse impact on patient outcomes. Few studies have been conducted\ud to obtain the patient’s perspective on the experience of anxiety and the events and\ud situations that aggravate and ameliorate it.\ud Method. The study used a mixed method approach. The sample consisted of women\ud undergoing planned gynaecological surgery. Anxiety was assessed using the State\ud Trait Anxiety Inventory. Trait anxiety was measured at the time of recruitment.\ud State anxiety was then assessed at six time points during the pre- and postoperative\ud periods. Postoperative pain was also measured using a 10 cm visual analogue scale.\ud Taped semi-structured telephone interviews were conducted approximately a week\ud after discharge.\ud Results. State anxiety rose steadily from the night before surgery to the point of\ud leaving the ward to go to theatre. Anxiety then increased sharply prior to the\ud anaesthetic decreasing sharply afterwards. Patients with higher levels of trait anxiety\ud were more likely to experience higher levels of anxiety throughout their admission.\ud Elevated levels of pre- and postoperative anxiety were associated with increased\ud levels of postoperative pain. Telephone interviews revealed a range of events/situations\ud that patients recalled distressing them and many were related to inadequate\ud information.\ud Conclusion. This study found higher rates of anxiety than previously reported and\ud anxiety levels appeared raised before admission to hospital. This has important\ud clinical and research implications.Relevance to clinical practice. Patients with high levels of anxiety may be identified\ud preoperatively and interventions designed to reduce anxiety could be targeted to this\ud vulnerable group. Patient experiences can inform the delivery of services to meet\ud their health needs better.

The ability to use the Internet is an essential skill for nursing students, both to support their studies, especially as nursing students spend a lot of their time in placements away from the university campus, and to support their development of skills in using what is becoming an increasingly essential tool for professionals. A study at Bournemouth University, England, found that new student nurses had poor Internet skills and were not frequent users prior to starting the course.\ud \ud No link was found between the students’ ages and their Internet use or skills. A clear link was however found between ability and frequency of use, except in relationship to the students’ ability to conduct an effective search. Almost half of the respondents said that they find far too much irrelevant information when searching for information on the Internet.\ud \ud Given the importance of Information and Technology skills to nurses, both as lifelong learners and as competent practitioners and to nursing students throughout their pre-registration education, the inclusion of a programme to ensure that they develop these skills during their pre-registration education is essential. \ud
