Abstract:
Nickel nanoparticies (NNPs) were synthesized by reduction of nickel (II) using poiy(vinyl alcohol) (PVA) as a capping agent. The NNPs were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy and X-ray diffraction (XRD) techniques. The addition of PVA has been found to profoundly influence the size, agglomeration and distribution of NNPs. The average diameters of NNPs are in the range of 3-7 nm in presence of PVA. XRD data indicate that NNPs are crystalline with face centered cubic structures. SEM images show the existence of secondary structures such as clusters and loops resulted from interactions between particles. The sizes of the NNPs were by and large uniform due to the use of PVA as the capping agent. FT-IR and thermogravimetric analyses confirm the interaction of PVA w ith NNPs to offer improved thermal stability Asiat. Soc. Bangladesh, Sci. 40(2): 197-205, December 2014

Abstract:
AbstractThe Nestlé Nutritional Profiling System (NNPS) has been developed to guide food and beverage reformulation. The WHO published guidelines to develop and validate nutrient profiling systems. The objective was to conduct validation tests of the NNPS following principles of the WHO guidelines. French (Individual and National Survey on food Consumption 2006–2007) and the USA (National Health and Nutrition Examination Surveys 2011–2012) nationally representative dietary surveys were used. NNPS outcomes (PASS, FAIL, out-of-scope) of foods were compared with the validated UK Ofcom nutrient profiling system outcomes. Contributions of NNPS outcomes to energy intakes were compared between diets nutritional quality classes defined by two methods: based on a food-based quality indicator (Programme National Nutrition Santé Guideline Score in France, Healthy Eating Index 2010 in the USA) or on a combination of three nutrient-based indicators (mean adequacy ratio, mean excess ratio and energy density). In both countries, food items with a NNPS FAIL outcome had a lower nutritional quality according to the UK Ofcom, with an overall agreement between the two systems of 75·7 % in France and 68·8 % in the USA. In both countries, a high (respectively, low) contribution of NNPS PASS (respectively, NNPS FAIL) was positively associated with diet healthiness. Absolute associations were stronger between the contribution of NNPS FAIL products and measures of diet healthiness. Foods and beverages reaching NNPS standards appeared to have a higher nutritional quality and would be more likely to contribute to healthier diets, mainly linked to a reduction of nutrients to limit.

Abstract:
Urbanism and communities centralization enlarges atmospheric pollution that affects both human beings as well as their constructed buildings. Different scientific and technological studies are being conducted, both in academic and construction industry, aiming the development of new construction materials with properties that can decrease visual pollution of cities, reducing also the number of cleanings required. The present research work aims the study and the production of self-cleaning ceramic surfaces in an economical and viable way without changing aesthetical aspect of material substrates used. The use of TiO2 nanoparticles (TiO2-NNPs) represents an attractive way to generate self-cleaning surfaces, therefore promoting the degradation of pollutant agents and reducing cleaning maintenance costs. In order to impart self-cleaning properties to ceramic surfaces, TiO2-NNPs based layers were deposited on different ceramic material substrates using the dip-coating method. The Photocatalytic activity (degradation of pollutants adsorbed on the surface) of the TiO2-NNPs based layers was characterized via the decomposition rate of an aqueous solution of Methylene blue (MB) under UV light irradiation. Colourless layers were successfully produced onto gray and white ceramic substrates using this sol-gel technique, without changing their aesthetical appearance. It was observed that the best photocatalytic activity was exhibited by the most porous ceramic substrate (gray); nevertheless, all the TiO2-NNPs coated ceramic surfaces showed good photocatalytic efficiency.

Abstract:
It is widely recognised that conservation policies in protected areas must also favour the development and viability of human populations. Although much research has focused on economic consequences, understanding the real impact of conservation on local populations requires a more holistic standpoint. Using quasi-experimental matching methods and a diachronic perspective, the biodemographic and socio-economic effects of Colombia’s National Natural Parks (NNPs) were evaluated (all in a context of internal conflict and post-conflict). The analyses were made for the set of NNPs and then grouped into four natural regions (Andes, Caribbean, Amazon-Orinoquía and Pacific) and two conflict intensities. Differences were found mainly for NNPs with low-intensity conflict, but only for biodemographic variables, not for socio-economic ones. Starting from a situation of disadvantage, a relative improvement in the conditions of the NNP municipalities was observed throughout the 13-year period in relation to the control group. Results should be taken with caution due to the conflict situation, but the lack of correlation between biodemographic and socio-economic aspects highlights the need to include more complex approaches in protected area management policies.

Abstract:
To compare the knowledge and problem-solving, communication, and clinical skills of graduating neonatal nurse practitioners (NNPs) and pediatric residents, a cohort study was conducted in a 33-bed tertiary-level neonatal intensive care unit in a 400-bed teaching hospital affiliated with a faculty of health sciences. Participants were all (n = 10) NNP graduates from the first 3 years of the educational program and 13 (87%) of 15 second-year pediatric residents. One hundred multiple-choice questions and 20 radiographic slides were used to test knowledge; a semistructured oral examination tested problem-solving skills; three simulated interactions with parents tested communication skills; and seven simulated procedures tested clinical skills. Graduating NNPs scored similarly to the pediatric residents on the multiple-choice questions (difference –3.4%; 95% confidence interval [CI] around difference –9.7, 2.9), radiographs (difference –1.4%; 95% CI –11.5, 8.7), oral examination (difference 2.8%; 95% CI –11.1, 16.7), communication skills (simulated parents assessment: difference 0.8%; 95% CI –4.2, 5.7; expert observer assessment: difference 5.8%; 95% CI –2.8, 14.3), and clinical skills (difference 7.4%; 95% CI –5.5, 20.2). The NNPs about to graduate from their educational program showed knowledge and problem-solving, communication, and clinical skills equivalent to those of second-year pediatric residents and are thus likely to deliver comparable care in the clinical setting. The results support the adoption of the NNP role.

Abstract:
Objectives: To quantify and validate the effect of pixel size on a digital intraoral radiographic system according to International Electrotechnical Commission standards through physical and visual evaluations. Methods: The digital intraoral radiographic system used was the photostimulable phosphor imaging plate and scanner system. The system had three image capture modes: high-speed (HS), high-resolution (HR), and super high-resolution (SHR) with different pixels. The physical characteristics of the system were evaluated using presampled modulation transfer function (MTF) and the normalized noise power spectrum (NNPS). An aluminum (Al) step phantom with different depths of holes was used to acquire images under various exposure conditions. The average number of perceptible holes from all steps was plotted against each exposure dose. The results were compared to analyze the effects of pixel size on image quality of intraoral radiographs. Results: The MTF was slightly higher with SHR than with HR and HS. The NNPS with SHR showed about a 40% decrease in magnitude compared to HS. The total number of perceptible holes in the Al step phantom was higher with SHR than with HS and HR in all exposure conditions. Conclusions: The MTF and NNPS obtained with different pixel size could be quantified by physical evaluation, and the differences were visually validated with Al step phantom. The SHR mode has the potential to decrease the radiation dose without compromising the image quality.

A crescente demanda por produtos com maior performance, menor custo de fabrica??o, menos impactantes ao meio ambiente que sejam mais eficientes energeticamente, t?m fomentado pesquisas em diversas ?reas da nanoci?ncia e nanotecnologia (N&N), visando sobrepujar estas limita??es ou agregando as principais vantagens dos nanocomp?sitos e nanofluidos (NF) os quais tem sido extensivamente aplicados nas ind?strias. O objetivo deste trabalho foi estudar as caracter?sticas de nanolubrificantes (NL) aditivado com nanopart?culas (NPs) de ?ndio (In), para poder contribuir com a redu??o significativa do tamanho, peso e custos dos sistemas de transfer?ncia de calor, tendo estes uma melhor estabilidade mec?nica, uma menor resist?ncia ao atrito e desgaste, e que possuia uma melhor ader?ncia em regime de lubrifica??o limite. Para estes fins, ap?s a aquisi??o das NPs de In, foram preparados tr?s nanolubrificantes (NLs) distintos, adicionando-se 0,3 g/L aos ?leos de compressores de refrigera??o herm?ticos o ISO68, ISO32, e o Poliol ?ster (POE). Ap?s o processo de prepara??o que consiste na desfragmenta??o e homogeneiza??o, cada composto foi ensaiado em banho termost?tico e com o aux?lio de um re?metro e um condutiv?metro, foi mensurados os valores relativos ?s suas propriedades t?rmicas, para comprovar as propriedades requisitadas. A estabilidade mec?nica foi verificada atrav?s de compara??es cronol?gicas, potencial zeta e aglomera??o de part?culas, ap?s passou-se por ensaios de lubricidade utilizando-se os trib?metos de sonda com movimento alternado em alta frequ?ncia (High Frequency Reciprocating Rig ? HFRR) e ensaio de pino contra disco para an?lise de desempenho tribol?gico. Os corpos de prova dos ensaios foram analisados em MEV (Microscopia eletr?nica de varredura) e EDS (Espectr?metro de Dispers?o de Energia) para comprova??o dos resultados, onde foram realizadas analises dos modelos desenvolvidos, levando em considera??o par?metros como: coeficiente de fric??o, for?a de atrito, desgaste etetivo, composi??o final dos corpos de prova a aglomera??o das part?culas nos NLs, a temperatura e a viscosidade do fluido, e movimento Browniano das part?culas, entre outros. Os NLs compostos por In foram vi?veis, n?o se fazendo necess?ria a utiliza??o de tensoativos para melhorar a sua estabilidade, pois apresentaram resultados satisfat?rios nos ensaios tribol?gicos, mostrando-se com propriedades de lubrificantes de extrema press?o (EP), melhorando significativamente o desempenho tribol?gico. Assim, torna-se vi?vel a utiliza??o NLs gerados a partir de NP de In na lubrifica??o de compressores herm?ticos de refrigera??o.
The increasing demand for products with higher performance, lower manufacturing cost, less impactful to the environment and are more energy efficient, have fostered research in various areas of nanoscience and nanotechnology (N&N), aiming at overcoming these limitations or adding the main advantages of nanocomposites and nanofluids (NF) which have been extensively applied in industries. The objective of this work was to study the characteristics of nano-lubricants (NL) added with nanoparticles (NPs) of indium (In), In order to contribute to the significant reduction of the size, weight and costs of heat transfer systems, which have a better mechanical stability, a lower resistance to friction and wear, and a better adhesion in the limit lubrication regime. For these purposes, after the acquisition of In NPs, three separate nanolubrificantes (NLs) were prepared, adding 0.3 g / L to hermetic refrigeration compressor oils ISO68, ISO32, and Polyol Ester (POE). After the preparation process consisting of defragmentation and homogenization, each compound was tested in a thermostatic bath and with the aid of a rheometer and a conductivity meter, where the values relative to their thermal properties are measured, to verify the required properties. The mechanical stability was verified through chronological comparisons, Zeta potential and particle agglomeration, after being subjected to lubricity tests using probe tribromes with High Frequency Reciprocating Rig ? HFRR and pin-to-disk test for tribological performance analysis. The test specimens were analyzed in SEM (Scanning Electron Microscopy) and EDS (Energy Scattering Spectrometer) to prove the results, where analyzes of the developed models were carried out, taking into account parameters such as: Friction coefficient, friction force, wear resistance, final composition of the test specimens as well as the agglomeration of the particles in the NLs, temperature and viscosity of the fluid, and Brownian motion of the particles, among others. The NLs comprised of In were feasible, with the use of surfactants not being necessary to improve the stabilities, presented satisfactory results in the tribological tests, showing with properties of extreme pressure lubricants (EP), significantly improving the tribological performance. Thus, it becomes feasible to use NLs generated from NP of In in the lubrication of hermetic refrigeration compressors.

Abstract:
This study is a partial replication of Pica et al’s study (1989) of comprehensible output, and investigates comprehensible output in NNS-NNS interaction in Japanese as a Foreign Language. Data were collected using two different types of tasks (information gap and jigsaw tasks) in three sub-groups of different proficiency levels (High-High, Low-Low, and High-Low) in order to find out (1) to what extent the tasks provide opportunities for learners to modify their initial output in response to requests for clarification and confirmation, and (2) the extent to which learners actually modify their output in response to interlocutor requests.
The results show that comprehensible output is an important phenomenon in NNS-NNS interaction. Unlike the result of Pica et al, task types had more effect on opportunities for comprehensible output and actual production of comprehensible output than request types. Not much difference was found among different proficiency groups.

Abstract:

In skeletal muscle, loss of neuronal nitric oxide synthase (nNOS) from the sarcolemma has been observed in a few muscular dystrophies and myopathies. However, the extent of this phenomenon, its mechanism, and its physiological impact are not well understood. Using immunofluorescent staining for nNOS, a survey of 161 patient biopsies found absent or reduced sarcolemmal nNOS in 43% of patients. Patient mobility and muscle functional status correlated with nNOS mislocalization from the sarcolemma. Mouse models of inherited and acquired myopathies showed similar loss of sarcolemmal nNOS and impaired mobility and muscle function. A proteomic approach, using mass spectrometry and differentially labeled control and steroid-induced myopathy (SIM) mouse samples, found novel nNOS binding proteins including alpha-actinin-3 (ACTN3), which exhibited decreased interaction with nNOS after steroid treatment. It revealed a potential explanation for impaired muscle function in SIM as nNOS interactions were lost at the sarcomere and gained at the sarcoplasmic reticulum impairing contractility. Treating nNOS-deficient mice with steroids demonstrated that loss of sarcolemmal nNOS reduces muscle contractility and strength in SIM through increased nitric oxide (NO) signaling. In SIM mice treated with a nitric oxide donor and steroids, nitric oxide partially protects the muscle from atrophy and improves muscle fatigability and recovery suggesting nNOS mislocalization also decreases NO availability. These findings show that loss of sarcolemmal nNOS is a common phenomenon that negatively impacts muscle function. Therapeutic strategies targeting nNOS or NO signaling need to allow for the complexity of local nitric oxide content and cellular context.

Abstract:
Recent studies have begun to redefine the idea of accuracy in second language acquisition to include not only grammatical correctness, but also native-like selection. This is an exploratory study aimed at identifying areas of nonnative-like selection of adverbs, such as sentence position, semantic category preferences, frequency of use and breadth of word choice. Using corpus-linguistic methods it compares the writing of nonnative English speakers at an intermediate and advanced level to both American college students’ writing and published academic writing. It also conducts in-depth case studies of three of the most commonly used adverbs. It finds that while advanced students are grammatically accurate, there are still several ways in which their use of adverbs differs from that of native speakers.

Abstract:
This study examined the effects of prenatal exposure to methadone on clinical and neurobehavioural outcomes of infants between 40 and 42 weeks gestation. The aims of this study were: (a) to describe clinical and neurobehavioural outcomes of infants exposed to methadone during pregnancy, (b) to examine the effects of maternal methadone dose during pregnancy on infant clinical and neurobehavioural measures, and (c) to examine the extent to which associations between exposure to methadone during pregnancy and infant outcomes persisted after statistical control for a range of confounding variables. Two groups of study infants were recruited. These consisted of 51 consecutively recruited infants born to mothers maintained on methadone during their pregnancy and 42 randomly identified non-methadone exposed comparison infants. Prior to her child's birth, each pregnant woman completed a comprehensive maternal interview. At birth and during the infant's hospital stay a broad perinatal data-base was collected. At 42 weeks gestation infants underwent a neurobehavioural assessment including the NICU Network Neurobehavioural Scale (NNNS; Lester & Tronick, 2004) and infant cry analysis. Study results showed significant differences across several clinical and neurobehavioural measures. Infants exposed to methadone in utero were found to be significantly lighter, have smaller head circumferences, and spend longer in hospital. Neurobehaviourally, they were significantly less well regulated, less attentive, more easily aroused, more excitable, and more hypertonic. In addition, they exhibited less motor maturity, displayed more stress abstinence symptomatology, and required more support from the assessor in order to remain in an appropriate state. Concurrent analysis of infant cry characteristics revealed no significant differences between the fundamental frequencies or the melody contours of the two groups. However, infants prenatally exposed to methadone did display higher levels of frequency perturbation in their cries, as evidenced by analysis of their jitter factor and percentage of directional jitter. Analysis of the effects of maternal dose during pregnancy suggested that maternal dose levels above 60mg/day were general indicative of poorer infant outcomes than those below 60mg/day, with significant linear trends occurring across a number of measures. The extent to which associations between methadone exposure during pregnancy and infant outcomes reflected either a) the direct effects of methadone exposure and/or b) the effects of confounding factors correlated with maternal methadone use was examined using regression analysis. The results of this analysis for infant clinical outcomes showed confounding variables attenuated the effects of methadone exposure on infant birth length and, to some degree, infant head circumference. In contrast, associations between methadone exposure during pregnancy and most neurobehavioural outcomes remained significant, suggesting that maternal methadone use during pregnancy is an important, independent predictor of infant neurobehavioural functioning. These findings support the view that prenatal exposure to methadone has at least short term impacts on the infant's central nervous system (CNS) development. Important implications of possible vulnerabilities faced by these infants and their families are discussed.

Penlington, Roger. "Operational characteristics of the NNPB plunger in the glass container industry." Thesis, Sheffield Hallam University, 1994. http://shura.shu.ac.uk/20218/.

Full text
Abstract:
Although glass containers are an everyday item the process responsible for their production is not scientifically understood. Developments have occurred slowly over many years, mostly on a trial and error basis and in response to economic pressures. The narrow neck press and blow (NNPB) process has evolved in recent years as a result of attempts to reduce container weight. The fundamental component of the NNPB process is the plunger which is responsible for the initiation of the cavity and control of glass distribution within the container. The NNPB plunger functions as a form tool and as a heat exchanger, thus requiring a carefully selected range of properties. The Engineer responsible for tooling selection and operation has a limited resource of scientific knowledge to enable the performance of the process to be optimised. The current NNPB plunger is subject to high rates of wear and is directly responsible for product defects, thermal instability and limits process speed. The work presented here is a scientific study of current NNPB plunger technology. The plunger has been investigated in relation to the requirements of the glass container forming process. The materials used have been examined, before and after use and their wear modes explained. The thermal properties of the plunger have, as far as is possible, been examined during the forming cycle. When combined with results from the characterisation of transformations occurring in the material, during its service life, operational requirements have been explained. The ability of the NNPB plunger to remove heat from the glass has been investigated, and has illustrated significant deficiencies in the current arrangement. Details are given as to how these deficiencies may be overcome to enable the Engineer to regain control of the process. As a result of the study many phenomena exhibited by the NNPB plunger are now understood and may be related to the performance of the process.

Abstract:
AbstractIn recent years, artificial intelligence and specifically artificial neural networks (NNs) have shown great success in solving complex, nonlinear problems in earth sciences. Despite their success, the strategies upon which NNs make decisions are hard to decipher, which prevents scientists from interpreting and building trust in the NN predictions; a highly desired and necessary condition for the further use and exploitation of NNs’ potential. Thus, a variety of methods have been recently introduced with the aim of attributing the NN predictions to specific features in the input space and explaining their strategy. The so-called eXplainable Artificial Intelligence (XAI) is already seeing great application in a plethora of fields, offering promising results and insights about the decision strategies of NNs. Here, we provide an overview of the most recent work from our group, applying XAI to meteorology and climate science. Specifically, we present results from satellite applications that include weather phenomena identification and image to image translation, applications to climate prediction at subseasonal to decadal timescales, and detection of forced climatic changes and anthropogenic footprint. We also summarize a recently introduced synthetic benchmark dataset that can be used to improve our understanding of different XAI methods and introduce objectivity into the assessment of their fidelity. With this overview, we aim to illustrate how gaining accurate insights about the NN decision strategy can help climate scientists and meteorologists improve practices in fine-tuning model architectures, calibrating trust in climate and weather prediction and attribution, and learning new science.

Abstract:
AbstractThis paper presents Verisig 2.0, a verification tool for closed-loop systems with neural network (NN) controllers. We focus on NNs with tanh/sigmoid activations and develop a Taylor-model-based reachability algorithm through Taylor model preconditioning and shrink wrapping. Furthermore, we provide a parallelized implementation that allows Verisig 2.0 to efficiently handle larger NNs than existing tools can. We provide an extensive evaluation over 10 benchmarks and compare Verisig 2.0 against three state-of-the-art verification tools. We show that Verisig 2.0 is both more accurate and faster, achieving speed-ups of up to 21x and 268x against different tools, respectively.

Abstract:
Abstract Long Term Operation (LTO) of nuclear power plants (NPPs) will play a key role to reach net zero target. Monitoring and predictive approach detecting in advance faulty SCCs conditions may provide a further key tool in LTO framework. Detecting anomalies may allow the transition from time-based to condition-based predictive maintenance of the NNPs. Predictive algorithms could reduce the number of unplanned outages caused by reactor system failures (one-day outage of a 1000-MW NPPs causes losses of about 500 k$), improving the capacity factor, and keeping high safety margin level of NPPs. To this end, innovative approach by unsupervised machine learning technique (ML) is proposed to detect anomalies of SSCs. Based on principal component analysis and mahalanobis distance is possible to detect in advance the failure of the components. To the purpose a 2D digital twin of primary nuclear pipe under nominal conditions (inner temperature of 300° and an internal pressure of 15.5 MPa) is implemented in finite element code to provide a dataset for unsupervised ML code. The algorithm is then tested under anomaly pattern that deviate from nominal conditions. The results show good code prediction capabilities anticipating the pipe failure. Traditional monitoring combined with ML technique may support LTO program increasing the safety and competitiveness of NPPs.

Abstract:
We consider the problem of certifying the individual fairness (IF) of feed-forward neural networks (NNs). In particular, we work with the epsilon-delta-IF formulation, which, given a NN and a similarity metric learnt from data, requires that the output difference between any pair of epsilon-similar individuals is bounded by a maximum decision tolerance delta >= 0. Working with a range of metrics, including the Mahalanobis distance, we propose a method to overapproximate the resulting optimisation problem using piecewise-linear functions to lower and upper bound the NN's non-linearities globally over the input space. We encode this computation as the solution of a Mixed-Integer Linear Programming problem and demonstrate that it can be used to compute IF guarantees on four datasets widely used for fairness benchmarking. We show how this formulation can be used to encourage models' fairness at training time by modifying the NN loss, and empirically confirm our approach yields NNs that are orders of magnitude fairer than state-of-the-art methods.

Abstract:
Abstract Designing optimal neural network (NN) architectures is a difficult and time-consuming task, especially when error resiliency and hardware efficiency are considered simultaneously. In our paper, we extend neural architecture search (NAS) to also optimize a NN’s error resilience and hardware related metrics in addition to classification accuarcy. To this end, we consider the error sensitivity of a NN on the architecture-level during NAS and additionally incorporate checksums into the network as an external error detection mechanism. With an additional computational overhead as low as 17% for the discovered architectures, checksums are an efficient method to effectively enhance the error resilience of NNs. Furthermore, the results show that cell-based NN architectures are able to maintain their error resilience characteristics when transferred to other tasks.

Abstract:
The objective of this study is to carry out modal analysis of nonlinear periodic structures using nonlinear normal modes (NNMs). The NNMs are computed numerically with a method developed in [18] that is using a combination of two techniques: a shooting procedure and a method for the continuation of periodic motion. The proposed methodology is applied to a simplified model of a perfectly cyclic bladed disk assembly with 30 sectors. The analysis shows that the considered model structure features NNMs characterized by strong energy localization in a few sectors. This feature has no linear counterpart, and its occurrence is associated with the frequency-energy dependence of nonlinear oscillations.
