Post Synthetic Defect Engineering of UiO-66 Metal–Organic Framework with An Iridium(III)-HEDTA Complex and Application in Water Oxidation Catalysis

Clean production of renewable fuels is a great challenge of our scientific community. Iridium complexes have demonstrated a superior catalytic activity in the water oxidation (WO) reaction, which is a crucial step in water splitting process. Herein, we have used a defective zirconium metal–organic framework (MOF) with UiO-66 structure as support of a highly active Ir complex based on EDTA with the formula [Ir(HEDTA)Cl]Na. The defects are induced by the partial substitution of terephthalic acid with smaller formate groups. Anchoring of the complex occurs through a post-synthetic exchange of formate anions, coordinated at the zirconium clusters of the MOF, with the free carboxylate group of the [Ir(HEDTA)Cl]− complex. The modified material was tested as a heterogeneous catalyst for the WO reaction by using cerium ammonium nitrate (CAN) as the sacrificial agent. Although turnover frequency (TOF) and turnover number (TON) values are comparable to those of other iridium heterogenized catalysts, the MOF exhibits iridium leaching not limited at the first catalytic run, as usually observed, suggesting a lack of stability of the hybrid system under strong oxidative conditions.
Precommitments: Two Field Experiments on Intertemporal Choice in Charitable Giving

This paper conducts two natural eld experiments to explore inter-temporal choices in charitable giving by varying the timing of commitment and payment. Monthly donors were asked to increase their contributions (1) immediately, (2) in one month, (2) in two months, (4) in a free number of months. The results are consistent between the two eld experiments; rst, mean increases in donations are signi cantly higher when donors are asked to precommit to future donations. Second, follow-up data show that there is no di¤erence in cancellations rates between the control and treatment groups. Finally, I provide evidence of heterogeneity in the response to di¤erent time lags, indicating di¤erences in inter-temporal preferences among donors.

CLINICAL SUPERVISION IN NURSING PRACTICE: A COMPARATIVE STUDY IN PORTUGAL AND THE UNITED KINGDOM

This research examines the practice of clinical supervision in nursing in both The United Kingdom and Portugal, one important pilar of safety care. The study was funded by the British Council under the Treaty of Windsor scheme. Forty five nurses from both countries completed questionnaires. One focus group interview was held in both countries involving three participants, six in total (only three volunteered) who had also completed the questionnaire. The quantitative data from the questionnaires were analysed using the Statistical Package for the Social Sciences and the qualitative data from both the questionnaires and the focus groups were analysed using Colaizzi’s (1978) framework. The findings suggest that clinical supervision has positive benefits for professional development of nurses and their clinical practice. Constraints are evident, particularly in The United Kingdom and these included lack of time, lack of understanding of clinical supervision and lack of commitment.Implications for Nursing Management: Managers need to support clinical supervision for it is important for quality care and evidence based practice. Protocols for clinical supervision practice would enable managers to lead and support staff’s professional development and help to ensure quality care within the organisation.
Detecting (absent) app-to-app authentication on cross-device short-distance channels

Short-distance or near-field communication is increasingly used by mobile apps for interacting or exchanging data in a cross-device fashion. In this paper, we identify a security issue, namely cross-device app-to-app communication hijacking (or CATCH), that affect Android apps using short-distance channels (e.g., Bluetooth and Wi-Fi-Direct). This issue causes unauthenticated or malicious app-to-app interactions even when the underlying communication channels are authenticated and secured. In addition to discovering the security issue, we design an algorithm based on data-flow analysis for detecting the presence of CATCH in Android apps. Our algorithm checks if a given app contains an app-to-app authentication scheme, necessary for preventing CATCH. We perform experiments on a set of Android apps and show the CATCH problem is always present on the whole analyzed applications set. We also discuss the impact of the problem in real scenarios by presenting two real case studies. At the end of the paper we reported limitations of our model along with future improvements.
Effect of Silica Compounds on Vegetative Growth, Yield, Fruit Quality and Nutritional Status of Olinda Valencia orange

Field experiment was conducted on fruitful Olinda Valencia orange trees budded on Volcamer lemon rootstock grown in sandy soil under drip irrigation system at Modern Agriculture Company (PICO), Berquash orchard located in Giza Governorate during both (2013/14) and (2014/15) experimental seasons to study the influence of foliar application with two silicate sources potassium silicate and magnesium silicate each at two concentrations either solely or in combination on vegetative growth, yield, quality and nutritional status of Olinda Valencia orange. All evaluated growth parameters: (shoot length, diameter, number of leaves per shoot and canopy measurements i.e, tree height , diameter and volume) were enhanced by all investigated silicate treatments, however combination of K & Mg silicate sources each at its higher concentration (4.0 & 0.8% respectively) was the most effective particularly with 3 canopy parameters. Percentage of fruit set & retention and harvested fruits either per feddan in ton or number and weight in Kg per tree were significantly increased by all silicate treatments. However, K silicate spray alone at 2.0% tended generally to be more effective for increasing weight of fruits per tree or Feddan. Fruit physical properties as average fruit weight, volume, dimensions, shape index, juice weight as well as rind thickness, firmness and color as Hue angle values were increased by various investigated silicate treatments except shape index took the other way around and rind color was inhanced. In most cases potassium silicate alone at 2.0% was the most effective except with rind thickness and its firmness whereas magnesium silicate solely or in combination was the superior. Fruit chemical properties as TSS %, acidity %, TSS/acid ratio and V.C content in most cases were significantly decreased than control, except TSS/ Acid ratio was increased. Leaf moisture, leaf N, P, K, Si, Mg, Fe, Zn, Mn and Cu contents were varied in response, whereas leaf N, P, K, Si, Mg, Fe, Mn and Cu contents were increased by all investigated silicate spray treatments, while Zinc and moisture content weren’t affected. Anyhow, potassium silicate spray at 4.0% solely or combined to 0.8% magnesium silicate were significantly the superior for leaf N & K content, while higher Mg silicate solely or combined with 4.0% potassium silicate were the most effective for leaf P & Mg content. In addition, all silicate treatments increased significantly leaf Si, Fe, Mn and Cu contents but they didn’t statistically differ as compared each other.
Characterization of Asphaltenes and Resins Separated from Water-in-Crude Oil Emulsions Formed in Kuwaiti Oil Fields

Knowledge of the properties and behavior of asphaltenes and resins is indispensable for the design of preventive and curative measure for emulsion problems created by the presence of asphaltene, resins and other organic and inorganic solids. In order to understand the phenomena of water-oil emulsions formed in Kuwaiti oil fields and determine the factors involved in the stabilization of these emulsions, the role of asphaltenes, resins and wax separated from various samples of oil field emulsions formed in Burgan oil field have been evaluated. Physicochemical properties of asphaltenes, resins, wax, and de-asphalted deresined (DADR) oil samples have been studied via FT-IR, H and C NMR, elemental analysis, and differential scanning calorimetry (DSC). These emulsion samples contain different amount of water ranges from 24 to 35%, asphaltenes content ranges from 0.9 to 1.7%, resins content from3.7 to 4.6%. IR-FT spectra were performed to identify the various functional groups which have an effect on the stability of water-oil emulsions. The freezing behavior of an emulsion was characterized by differential scanning calorimetry to determine whether the water in the emulsion is free water or emulsified water.
Psychiatric/Mental Health Nursing: Positioning Undergraduate Education

The effectiveness of undergraduate comprehensive nursing programmes to prepare nurses to practice in the field of mental health is of concern to practitioners, educators and service providers. A crisis in the recruitment and retention of nurses to this field of practice is often linked to the marginalised position of psychiatric/mental health nursing within the comprehensive curriculum. In this paper the critique of the mental health component of comprehensive nursing education and the questions that it raises are explored from historical, structural and ideological perspectives. In order to locate the past and highlight its significance to where psychiatric/inental health nurses find themselves today some of the history of the asylum system and the development of psychiatric nursing in New Zealand within these structures are presented. Ideological changes to the way mental health was thought about and responded to have had considerable impact on where psychiatric nurses practiced, how they practised and what they were named. This created the need for a different kind of nurse and has led to changes in the education of nurses. The structural influences on the training and education of nurses are identified through relevant reports and their recommendations and significance in relation to psychiatric/mental health nursing are examined. Issues deriving from the critique of undergraduate psychiatric/mental health nursing education highlight the urgent nature of the crisis and draw out the multiple and competing discourses that inform the education of nurses. In acknowledging that the crisis can he viewed from multiple perspectives the need for responses from multiple levels involving the Nursing Council of New Zealand, the Ministry of Health, the Mental Health Commission and nurses in education and practice are recommended.
Technology Is The Tool, Teaching Is The Task: Student Satisfaction In Distance Learning

A study was conducted to determine predictors of student satisfaction in a graduate nursing program taught via fully interactive, multipoint real-time video teleconferencing and World Wide Web/Internet. A correlational research design was used to examine relationships among five learner attributes, three instructional variables, and student satisfaction. The five learner attribute predictors were: (1) previous experience with courses taught via technology; (2) self-ratings of competence with technology; (3) frequency of between-class usage of communications technology; (4) age; and (5) remote-site group size. Instructional variables included instructor/instruction, technology, and course management. Regression analyses identified learner attributes and instructional variables predictive of student satisfaction. Of the eight predictor variables regressed on the measure of student satisfaction, only instructor/instruction contributes to explanation of the variance in course satisfaction scores. Overall instructor rating strongly correlated with satisfaction. The most potent finding is that good pedagogy is important to students' perceived satisfaction with distance education. The focus of faculty training and development for those who instruct in distance education courses should be directed to development of effective instructional strategies.

Revisiting the Role of Feature Engineering for Compound Type Identification in Sanskrit

We propose an automated approach for semantic class identi(cid:12)cation of compounds in San-skrit. It is essential to extract semantic information hidden in compounds for improving overall downstream Natural Language Processing (NLP) applications such as information extraction, question answering, machine translation, and many more. In this work, we systematically investigate the following research question: Can recent advances in neural network outperform traditional hand engineered feature based methods on the semantic level multi-class compound classi(cid:12)cation task for Sanskrit? Contrary to the previous methods, our method does not require feature engineering. For well-organized analysis, we categorize neural systems based on Multi-Layer Perceptron (MLP), Convolution Neural Network (CNN) and Long Short Term Memory (LSTM) architecture and feed input to the system from one of the possible levels, namely, word level, sub-word level, and character level. Our best system with LSTM architecture and FastText embedding with end-to-end training has shown promising results in terms of F-score (0.73) compared to the state of the art method based on feature engineering (0.74) and outperformed in terms of accuracy (77.68%).
Molecular Dynamics Simulation of the Superspreading of Surfactant-Laden Droplets. A Review

Superspreading is the rapid and complete spreading of surfactant-laden droplets on hydrophobic substrates. This phenomenon has been studied for many decades by experiment, theory, and simulation, but it has been only recently that molecular-level simulation has provided significant insights into the underlying mechanisms of superspreading thanks to the development of accurate force-fields and the increase of computational capabilities. Here, we review the main advances in this area that have surfaced from Molecular Dynamics simulation of all-atom and coarse-grained models highlighting and contrasting the main results and discussing various elements of the proposed mechanisms for superspreading. We anticipate that this review will stimulate further research on the interpretation of experimental results and the design of surfactants for applications requiring efficient spreading, such as coating technology.
Academic Proposal for Heritage Intervention in a BIM Environment for a 19th Century Flour Factory

The implementation of building information modeling (BIM) has become a reality worldwide, not only because of the advantages it offers, but also because of the obligatory nature of its use in construction and civil engineering projects in various countries around the world. An intervention project on an industrial heritage property requires a methodology that considers the condition of the building over time and its value for new use. The advantages of working with a precise 3D model that integrates engineering data in a collaborative work environment makes BIM and heritage BIM (HBIM) very useful tools in a project whose objective is the recovery of an industrial heritage real estate property. This work is part of the academic implementation of BIM in university technical education centers and aims to establish a methodology for shared and collaborative group work in a BIM environment through a Spanish industrial heritage case study of a flour factory dating to 1865. A rigorous historical study and the elaboration of a central BIM model loaded with real content on the industrial complex have allowed the immersion of the students into the BIM methodology, as well as the generation of a value proposition for the exploitation of the factory.
Stem Cells as Therapeutic Option in Periodontal Regeneration: A Myth or a Reality?

DOI: 10.21276/sjbr.2018. 3.3. 2 Abstract: Periodontitis are multifactorial infections that begin with a period of inflammation of the supporting tissues of the teeth and then progress destroying the tissues until loss of the teeth. The goal of periodontal treatment is to stop the progression of the disease, restore functions and regenerate the damaged tissue. However, regeneration of different tissues, by conventional treatments, still remains great challenge. To address this, there are several approaches to tissue engineering for regenerative dentistry, among them, the use of stem cells by including dental pulp stem cells (DPSCS), periodontal ligament stem cells (PDLSCS), stem cells from the dental apical papilla (SCAPS), stem cells from human exfoliated deciduous teeth (SHEDS), dental follicle stem cells (DFSCS), dental epithelial stem cells (DESCS), bone marrow mesenchymal stem cells (BMMSCS), adipose-derived stem cells (ADSCS), embryonicstem cells (ESCS) and induced pluripotent stem cells (IPSCS). This novel approach may represent an effective therapeutic tool for periodontal regeneration. However, there are still obscurities regarding the mechanisms underlying in periodontal regeneration and challenges in applications of dental stem cell. Further efforts are necessary before moving to clinical trials for future applications.
Effects of Hybridisation on the Low Velocity Falling Weight Impact and Flexural Properties of Flax-Carbon/Epoxy Hybrid Composites

The trend of research and adoption of natural plant-based fibre reinforced composites is increasing, with traditional synthetic fibres such as carbon and glass experiencing restrictions placed on their manufacture and use by legislative bodies due to their environmental impact through the entire product life cycle. Finding suitable alternatives to lightweight and high-performance synthetic composites will be of benefit to the automotive, marine and aerospace industries. This paper investigates the low-velocity impact (LVI) and flexural properties and damage characteristics of flax-carbon/epoxy hybrid composites to be used in structural lightweight applications. LVI, for example, is analogous to several real-life situations, such as damage during manufacture, feasibly due to human error such as the dropping of tools and mishandling of the finished product, debris strikes of aircraft flight, or even the collision of a vessel with another. Carbon fibre has been hybridised with flax fibres to achieve enhanced impact and flexural performance. The failure mechanisms of woven flax and flax-carbon epoxy hybrid composites have been further analysed using Scanning Electron Microscopy (SEM). It was observed from the experimental results that carbon fibre hybridisation has a significant effect on the impact and flexural properties and their damage modes. The results obtained from this study exhibited that the flexural strength and modulus of plain flax/epoxy composite increase significantly from 95.66 MPa to 425.87 MPa and 4.78 GPa to 17.90 GPa, respectively, with carbon fibre hybridisation. This significant improvement in flexural properties would provide designers with important information to make informed decisions during material selection for lightweight structural applications.
Elemental Mercury Exposure and Sleep Disorder

The sleep-wake rhythms cycle coincides with the solar 24-hour schedule. Most adult subjects in nontropical areas are comfortable with 6.5 to 8.0 hours of daily sleep, taken in a single period. It is known that normal sleep consists of four to six behaviourally and electrophysiologically (EEG) defined cycles. Sleep is divided in two main types: REM (rapid eye movements) sleep and non-REM sleep. In the general population, sleep disorders are common and usually associated with some illness, psychological and social disturbances. Insomnia as the most common sleep disorder is most often the consequence of psychological disturbances. It is characterized by the inability to fall asleep quickly. Sleepwalking, night terrors and nightmares are parasomnias which often reflect significant stress or physiopathology. Restless legs syndrome and periodic limb movements are a type of motor disorders. Restless legs usually occur before sleep onset, while periodic limb movements can fragment the sleep. Transient sleep disturbances are mostly associated with variety of factors including stress, life changes, shift work, jet lag, and some acute health disorders. The most popular drugs, such as alcohol, nicotine and caffeine, can adversely affect the quality and quantity of sleep (Hornyak et al., 2006; Lee & Douglass, 2010; Pinel, 2009; Vgontzas et al., 2010). Occupational exposure to heavy metals, such as cadmium, lead, manganese and mercury, was very frequent in the 20th century. Many epidemiological studies show that these heavy metals can cause serious functional disability among exposed workers (World Health Organization [WHO], 1980). Inorganic lead, manganese and inorganic-elemental mercury (Hg) exposure can, among others, cause neurotoxic effects with a typical, but different, clinical picture associated with sleep disorder. Hg a silvery-white liquid metal is quite attractive and very widespread which, despite being highly toxic, was used by humans as a medicine for thousands of years. We shall discuss its neurotoxic effects and the sleep disorders it can cause at increased occupational exposure. Hg was first described by Aristotle in the 4th century A.D., and the alchemist’s concept of Hg leaned on his system of natural phenomena, which dominated all of science until the 17th century. For this reason Hg was attributed with all those qualities of nature that accelerate development, growth and maturation. The famous Arabian physician Avicena, who was active in the 11th century, wrote that Hg vapours cause paralysis, tremor
