Published: September 2018

Supramolecular catalysis involves the design and characterization of synthetic macromolecules that catalyze chemical reactions. While enzymes are often cited as the inspiration for such catalysts, enzymes can also serve as hosts for non-native catalytic components. Protein-based hosts can be readily produced in E. coli and rapidly evolved for particular applications. Moreover, inherent properties of these systems, including their conformational dynamics, can be exploited for non-native transformations that occur within their interior. Studies on the peptidase activity of a prolyl oligopeptidase from Pyrococcus furiosus (Pfu POP) suggest that its unique two-domain architecture regulates substrate access and specificity. We have established that Pfu POP also serves as an efficient host for asymmetric cyclopropanation upon active-site modification with a dirhodium cofactor. To understand how Pfu POP controls both peptidase and dirhodium catalysis, we determined the crystal structures of this enzyme and its S477C mutant and used these structures as starting points for MD simulations of both the apo structures and systems containing a covalently linked peptidase inhibitor or a dirhodium catalyst. Pfu POP was crystalized in an open conformation, and MD simulations reveal spontaneous transitions between open and closed states, in addition to a number of smaller scale conformational changes, suggesting facile inter-domain movement. Importantly, key aspects of previously reported peptidase kinetics and cyclopropanation selectivity can be rationalized in the context of this inter-domain opening and closing. This finding constitutes a remarkable example in which the conformational dynamics of a supramolecular host affect two different catalytic activities and suggests that Pfu POP could serve as a host for a wide range of non-native catalysts.
Dyskurs podręcznikowy a dyskurs dziecięcy – odmienne postrzeganie rzeczywistości

Published: September 2018

Textbooks have become a source of assistance that settled for good into Polish education landscape, a measure without which many adults cannot imagine the school reality. At the same time, the lack of the comprehensive studies on education packs is noticeable. What is more, the voice of children in Poland is marginalized or completely ignored, as opposed to the Western countries. The perspective of the youngest participants of the education process, who are the direct recipients of the textbook offer and are critical and thoughtful, is very rarely taken into account. Whereas their opinions may be a source of very powerful changes in education.

This article presents my own research results. The topic of undertaken study was the analysis of the most popular education packs for classes 1–3. The gathered data was enriched with third-grade students’ opinions about the tasks from the education packs and a description of their experiences related to the usage of those textbooks in school.

The study was conducted with a qualitative approach. As the study techniques, a documentary analysis and focus interviews (enriched with textbook tasks designed by children) were used. As resulting from the study, the textbook discourse is not a children’s discourse. Authors of these textbooks tend to forget about the real needs and capabilities of children. Students appeal for taking into account their high potential and putting into the textbooks subjects and tasks fitted to their development level, allowing them to take creative and divergent actions.
Bezrefleksyjna codzienność refleksyjnych uczniów, czyli polska edukacja wczesnoszkolna z podręcznikiem w tle
Authors: Szyller Aleksandra
Published: September 2018

This article presents my own research results. The research consists of the third-graders’ opinions about the textbook role and usefulness in the teaching process and the analysis of children’s experiences connected to the educational packets in the school practice. The qualitative data had been gathered trough focus interviews and enriched with the analysis of students’ works. As the research shows, the children’s negative perception of everyday school life seems to origin in the teachers’ admiration to go through the textbooks page by page and students’ subjection to the textbooks packets. Everyday work with the textbook forces children to make often anti-developmental tasks and to resign from divergent and creative thinking in favor of acting according to the designated algorithm. The modern school with the textbook on the pedestal is changing into a space with growing restrictions. The creation of independent subjects is giving place to the formation of other-directed individuals, lacking of the ability to think reflective, which is an important change catalyst.

This paper addresses the issue of these experiences collected by early education students of the University of Gdańsk and the Pomeranian Academy in Słupsk during teacher training in kindergarten which they specified as hard and presented in essays. Subjecting the events described to a qualitative analysis made it possible to unravel that (a) students find hard instances of children being harmed by teachers, particularly being treated with violence; (b) teacher trainees participate in these incidents as passive, helpless witnesses, as they do not know ways of protecting kindergarten children against maltreatment; (c) it is necessary to better prepare teachers-to-be for resolution of hard situations with children’s participation.
Aspiration Squeeze: The Struggle of Children to Positively Selected Immigrants
Authors: Engzell Per
Published: September 2018

Why is it that children of immigrants often outdo their ethnic majority peers in educational aspirations yet struggle to keep pace with their achievements? This article advances the explanation that many immigrant communities, while positively selected on education, still have moderate absolute levels of schooling. Therefore, parents' education may imbue children with high expectations but not always the means to fulfill them. Swedish data on children of immigrants from over 100 countries of origin support this view: net of parents' absolute years of schooling, a high rank in the sending country benefits children's aspirations, attitudes, and educational choices, but not their test scores or school grades. The upshot is an "aspiration squeeze" where, to emulate their parents' relative place in the education distribution, children are left struggling against the momentous tide of educational expansion.

Published: September 2018

The local communities of the Himalaya have been using fuel wood as one of the major sources of energy since millennia. Their dependency on these resources as primary source of fuel wood has resulted in unsustainable pressures on the forests. The present communication aims to access the fuel wood resource and consumption pattern of Bhotia, an ethnic community in a cold arid and buffer zone of Nanda Devi Biosphere Reserve, i.e. Niti valley in the Western Himalaya. Within the Niti valley, 87 households in six villages were surveyed using open and close-ended structured questionnaire. Use Index (I%) of each fuel wood species was calculated to evaluate the key species used by the inhabitants and their preferences. The study revealed use of 10 species for fuel wood (five species each of tree and shrub) by the Bhotias. Pinus wallichiana (I = 96.6%) followed by Cedrus deodara (93.1%) were the preferred tree species for fuel wood, while among shrubs, Juniperus indica and J. communis were extensively used. Fuel wood consumption in the Niti valley was much lower (1.6±0.2 kg household-1 day-1) than other villages in the Greater Himalaya (4.9±0.4 kg household-1 day-1). The seasonally employed which formed 23% of the surveyed households, collected almost twice as much fuel wood than the employed households (9.2±0.4 and 5.2±0.4 quintals season-1, respectively). As the area is characterized by sparse vegetation cover, low primary productivity and short growing season, and is thus highly susceptible to irreversible changes of natural habitats. The study suggests that providing alternate and non-conventional energy sources such as solar cookers and fuel efficient portable ovens to the inhabitants at subsidized rates could reduce the pressure on nearby forests. Botanica Orientalis – Journal of Plant Science (2017) 11: 1–6
Izrada mreže izvoznih putova i uzgojnih staza u šumama hrasta lužnjaka kao mjera učinkovitije njege i učinkovitijega korištenja šumskih resursa
Authors: Posarić Darko , Nikolić Stjepan
Published: September 2018

Osnivanje uzgojnih staza u svrhu jednostavnijega rada njege pomlatka i učinkovitije kontrole u Hrvatskoj, prvi je puta napravljeno 1977. godine u Šumariji Đurđenovac (Sabljak 1990) i Šumariji Cerna. Od tada se postupno proširilo kao prihvaćena tehnologija rada uglavnom u slavonskim podružnicama Hrvatskih šuma, dok je u ostalima slabo prihvaćeno. Hrvatske šume d.o.o. do danas nisu analizirale učinkovitost ove tehnologije, već je odluka o njezinu provođenju ili ne provođenju prepuštana Upravama šuma podružnicama, pa čak i šumarijama. Suština tehnologije odnosi se na formiranje pravilne mreže izvoznih putova okomitih na glavni put ili makadamsku cestu širine 3 m te okomito na njih uzgojnih staza širine 1,5 m. Proizvodna površina između staza različitih je širina u pojedinim UŠP-ima, ali najčešće iznosi 5 m. Mreža se formira u godini prvoga uzgojnog zahvata nakon dovršnoga sijeka (prije popunjavanja sadnicama ili njege pomlatka). Radnicima je rad sa staza jednostavniji i lakši, a posebice je učinkovita kontrola. S druge strane, pokosi se između 24 i 29 % već pomlađene površine, što je osnovni argument protivnicima ove tehnologije. U ovome radu predlaže se iskušati i drukačije razmake i položaje uzgojnih staza. Izvozni putovi izrađuju se kad i uzgojne staze, a koriste se za izvoženje drvnoga materijala od vremena početka proreda pa do kraja ophodnje. Razmak osi izvoznih putova u odjelima dimenzija 750 × 750 m je 37,5 m, čime se površina odjela podijeli na 20 jednakih dijelova. U odjelima drukčijih dimenzija razmak varira, najčešće između 40 i 50 m, a povećanje razmaka umanjuje učinkovitost izvoženja drva s njih. Stoga bi pokusno svakako trebalo ispitati i drukčije razmake osi izvoznih putova, na prvome mjestu onaj od 25 metara. Budući da o ovoj problematici kod nas ima iznimno malo pisanih materijala, a tehnologija je u primjeni dugi niz godina, ovaj rad ima za cilj opisati postojeće stanje, navesti dobre i loše strane osnivanja mreže izvoznih putova i uzgojnih staza te pokrenuti raspravu s konačnim ciljem definiranja optimalnoga načina rada, a posebice njegova unificiranja i primjene u svim šumama hrasta lužnjaka u nas.

Published: September 2018

Hepatitis C virus (HCV) affects more than 268,000 people in Canada. Both the Canadian Institutes of Health Research and the Public Health Agency of Canada recognize the significant impact of HCV-related liver diseases and supported the establishment of a national hepatitis C research network, the Canadian Network on Hepatitis C (CanHepC). Interferon-free direct-acting antiviral regimens lead to more than 95% cure rates in almost all patients with well-tolerated short-course therapy. However, the goal of eliminating HCV in Canada cannot be fully realized until we overcome the financial, geographical, cultural, and social barriers that affect the entire continuum of care from diagnosis and linkage to care through treatment and prevention of new and reinfections. Current practices face difficulties in reversing HCV-induced immunological defects, expanding treatment to neglected communities, combating reinfections and co-infections, and expediting and simplifying the processes of diagnosis and treatment. As part of its knowledge translation mandate, CanHepC has organized the annual Canadian symposium on hepatitis C since 2012. The theme of this year’s symposium, “Toward Elimination of HCV: How to Get There?” focused on identifying the requirements of our therapeutic strategies and health policies for the elimination of HCV in Canada.

The purpose of this article is selection and substantiate the construct materials for a mobile battery of thermal energy. To evaluate the impact of chemical corrosion on the structural materials of the tank-battery, and researching the strength of the tank-battery during transportation and determination the feasibility of introducing and effectiveness of investments in environmental measures on the example of the implementation of the discrete heating / cooling systems. A comparison has been made of the technical characteristics chosen for our studies of heat storage material - bischofite and sodium acetate trihydrate, which showed that both substances have certain advantages and limitations in their application. An experiment was carried out to determine the stability of the material for corrosion, after the 10 cycles of heating-cooling, the metal parts that were deposited in the bischofite solution remained virtually unchanged, no corrosion marks were observed. While specimens that were in the melt of sodium triacetate have obvious corrosion marks (except for a stainless steel sample). Particularly noticeable corrosion of samples that were on the verge of air and sodium triacetate. Thus, it has been confirmed that the use of hydrated salt melts requires additional measures to protect against corrosion of metals, and the use of polymer materials is limited by the temperature of their application. Calculations of the strength of the tank-accumulator at static and dynamic loads with the account of transportation are carried out. Taking into account the obtained results of Mises stress, the tensile stresses in the cut and stresses of bolted joints during rolling during transport under conditions of use of steel constructions are higher. In the course of determining the feasibility of implementing the project, it was tested and proposed to supplement the methods of calculating the investment of energy saving measures and projects by a fundamentally new method of strategic rapid analysis "3E". This method allows you to get a graphical representation of the result of the analysis and with a high degree of probability to determine the strategy of financing the implementation projects. The analysis is based on three main criteria, namely: energy, environmental and economic. These weighting criteria consist of a number of values that are necessary to obtain a likely return on the payback of the implementation project. The results of express analysis are clearly represented in the form of the area of permissible values on the triangular diagram, which we are invited to call the "3E triangle" in the initial words of words: Energy, Ecology and Economics. An economic analysis has also been conducted, which showed that the estimated payback period of the project is less than five years, and the volume of annual revenue from the sale of thermal energy and cold is 1470000 UAH. Thus, the project is attractive for investment.

Published: September 2018

In order to provide reliable and efficient thermal conversion, it is necessary to understand the physical and chemical properties of corn stover. The properties of corn stover depend on species, climatic and weather conditions, soil type, fertilizer input etc. Thus, it is necessary to study the fuel from various locations.

The present paper describes analysis results of corn stover from a single location in Kyiv region, Ukraine. The soil was fertilized with anhydrous ammonia 80 kg/ha. Elemental composition (W, A, C, H, S, N, O, Cl), calorific values, ash melting temperatures and ash chemical composition of the samples have been tested.

The comparative analysis of the samples with foreign analogues has been carried out. It is shown that the test samples of corn stover from Kyiv region are characterized by ash initial deformation temperatures of 1160 - 1200 °C. These temperatures are higher than the average agricultural biomass values and typical for woody biomass. The relatively high ash melting temperature reduces risks of sintering and deposit formation on the furnace inner surface.

Published: September 2018

An improved and efficient method for the synthesis of panobinostat was developed. The commercially available starting material 4-(chloromethyl)benzaldehyde was converted to ( E)-methyl 3-[4-(chloromethyl)phenyl]acrylate via the Wittig–Horner reaction and was then directly condensed with 2-(2-methyl-1 H-indol-3-yl)ethanamine to afford the key intermediate ( E)-methyl 3-[4-({[2-(2-methyl-1 H-indol-3-yl)ethyl]amino}methyl)phenyl]acrylate in a one-pot synthesis reactor. Subsequently a nucleophilic substitution reaction was carried out smoothly to generate the desired compound. The key intermediate and target compound were characterised by HRMS, 1H NMR and 13C NMR. This procedure is operationally simple and would be more suitable for industrial production.

Este trabajo exploratorio teoriza acerca del modo en que las redes sociales digitales favorecen, en tanto que tecnologías de la identidad, un modo de concebir y presentar la identidad individual en términos de autopromoción. Como resultado de la normalización de esta lógica –coherente con la cultura promocional del capitalismo tardío–, crece la incorporación de prácticas como la marca personal en la comunicación cotidiana de los sujetos, la percepción del perfil social como un micromedio de comunicación y la concepción de la red de contactos a modo de audiencia personal. En síntesis, se señalan cuatro tendencias centrales en la concepción y presentación de la identidad que favorecen estos servicios web: una concepción distribuida y fragmentaria del yo, donde las teselas de los massmedia se convierten en contenidos clave para expresar la subjetividad; una tendencia a la cuantificación de las relaciones y los afectos; la percepción de encontrarse en una ineludible competencia con los otros; y la normalización de la presentación audiovisual del yo como un material comunicativo capaz de atraer la atención y comunicar autenticidad.

Published: September 2018

Aluminum foam is a functional material which is highly porous with cells of stochastic geometry. In distinction to polymer foam, aluminum foam is electrically conductive and has typical applications in many engineering areas. Optimal design and manufacture of foam structure usually require detailed understanding of the electrical property of the aluminum foam. In this study, a three-dimensional finite element numerical model based on the statistic characteristics of the geometrical structure of the closed-cell aluminum foam was proposed. The proposed numerical method was applied to study the property of the current conduction and to clarify the dependence of the electrical conductivity on the porosity as well as the cell size. A shape factor defined based on the numerical simulation results is introduced to the theoretical model of the electrical conductivity regarding porosity, which can describe the relationship between the electrical conductivity and the porosity of the closed-cell aluminum foam properly. It was found that the porosity has a negative effect on the electrical conductivity in a power law approximately, while the cell size has a slight effect on the electrical conductivity of the closed-cell aluminum foam. Finally, the simulation results were compared to the experimental ones and their good agreement demonstrated the feasibility and accuracy of the proposed numerical model of the closed-cell metallic foam.

Published: September 2018

A précised and reproducible HPLC method was developed for simultaneous estimation of antidiabetic drug, pioglitazone HCl and antihypertensive losartan potassium. Diabetics are prone to hypertension hence co-administration of antihypertensive and antidiabetic drugs is most common. The method is applied for their determination in pure form, in pharmaceutical formulations and in plasma sample using a Phenomenex column (100×4.6 mm, 5 μm particle size) in an isocratic mode. The mobile phase consisted of aqueous phosphate buffer (0.05 M, pH 3.5) and acetonitrile (70:30, % v/v). The detection was carried out at 225 nm. The method was linear over the concentration range 0.5–7.0 μg/ml and 0.1–7.0 μg/ml for pioglitazone HCl and losartan potassium respectively. The analytical validation of the proposed method was carried out using ICH guidelines.
End-To-End Convolutional Neural Network Model for Gear Fault Diagnosis Based on Sound Signals
Authors: Yao Yong , Wang Honglei , Li Shaobo , Liu Zhonghao , Gui Gui , Dan Yabo , Hu Jianjun
Published: September 2018

Currently gear fault diagnosis is mainly based on vibration signals with a few studies on acoustic signal analysis. However, vibration signal acquisition is limited by its contact measuring while traditional acoustic-based gear fault diagnosis relies heavily on prior knowledge of signal processing techniques and diagnostic expertise. In this paper, a novel deep learning-based gear fault diagnosis method is proposed based on sound signal analysis. By establishing an end-to-end convolutional neural network (CNN), the time and frequency domain signals can be fed into the model as raw signals without feature engineering. Moreover, multi-channel information from different microphones can also be fused by CNN channels without using an extra fusion algorithm. Our experiment results show that our method achieved much better performance on gear fault diagnosis compared with other traditional gear fault diagnosis methods involving feature engineering. A publicly available sound signal dataset for gear fault diagnosis is also released and can be downloaded as instructed in the conclusion section.
Effect of Coil Width on Deformed Shape and Processing Efficiency during Ship Hull Forming by Induction Heating
Authors: Dong Hongbao , Zhao Yao , Yuan Hua
Published: September 2018

The main hull of a ship is made up of a large number of plates with complex curvatures. Line heating is one of the main approaches used in the forming of a ship hull plate. Because line heating is based on manual heating using a handheld oxyacetylene gun, the typical heating width is extremely narrow. With the development of computer control technology, a newly developed automated plate forming equipment is available and its heat source is typically an electromagnetic induction coil. The temperature field and the induction coil size are correlated. However, investigations into the induction coil size are scarce. In this study, the effect that the induction coil width has on both the forming shape and processing efficiency is investigated via simulation and test. The results show that a moderate expansion of the induction coil width at different input powers has an insignificant impact on forming shapes that is attainable by common line heating. However, as the heating width expands with the expansion of the induction coil width, the number of the processing lines via line heating is reduced which improves the processing efficiency.
Expansion, Excess and the Uncanny: Deadly Premonition and Twin Peaks
Authors: Novitz Julian
Published: September 2018

The influence of the cult television series Twin Peaks (1990–1991) can be detected in a wide range of videogames, from adventure, to roleplaying to survival horror titles. While many games variously draw upon the narrative, setting and imagery of the series for inspiration, certain elements of the distinctive uncanniness of Twin Peaks are difficult to translate into gameplay, particularly its ability consistently disrupt the expectations and emotional responses of its audience. This paper examines the ways in which the 2010 survival horror title Deadly Premonition replicates the uncanniness of Twin Peaks in both its narrative and gameplay, noting how it expands upon conceptualizations of the gamerly uncanny. It contends that Deadly Premonition’s awkward recombination of seemingly inconsistent and excessive gameplay features mirrors the ways in which David Lynch and Mark Frost draw upon and subvert audience expectations for police procedurals and soap operas in the original Twin Peaks in order to generate an uncanny effect. Furthermore, Deadly Premonition uses the theme of possession—a central element of the television series—to offer a diegetic exploration of the uncanny relationship between the player and their onscreen avatar. In these regards, Deadly Premonition provides a rare example of how the subversive uncanniness of Twin Peaks can be addressed through gameplay, rather than solely through the game’s narrative or representational elements.
Theoretical Study on the Hydrogenation Mechanisms of Model Compounds of Heavy Oil in a Plasma-Driven Catalytic System
Authors: Hao Haigang , Lian Pengfei , Gong Juhui , Gao Rui
Published: September 2018

Heavy oil will likely dominate the future energy market. Nevertheless, processing heavy oils using conventional technologies has to face the problems of high hydrogen partial pressure and catalyst deactivation. Our previous work reported a novel method to upgrade heavy oil using hydrogen non-thermal plasma under atmospheric pressure without a catalyst. However, the plasma-driven catalytic hydrogenation mechanism is still ambiguous. In this work, we investigated the intrinsic mechanism of hydrogenating heavy oil in a plasma-driven catalytic system based on density functional theory (DFT) calculations. Two model compounds, toluene and 4-ethyltoluene have been chosen to represent heavy oil, respectively; a hydrogen atom and ethyl radical have been chosen to represent the high reactivity species generated by plasma, respectively. DFT study results indicate that toluene is easily hydrogenated by hydrogen atoms, but hard to hydrocrack into benzene and methane; small radicals, like ethyl radicals, are prone to attach to the carbon atoms in aromatic rings, which is interpreted as the reason for the increased substitution index of trap oil. The present work investigated the hydrogenation mechanism of heavy oil in a plasma-driven catalytic system, both thermodynamically and kinetically.
Challenges of Decoding Transcription Factor Dynamics in Terms of Gene Regulation
Authors: Martin Erik W. , Sung Myong-Hee
Published: September 2018

Technological advances are continually improving our ability to obtain more accurate views about the inner workings of biological systems. One such rapidly evolving area is single cell biology, and in particular gene expression and its regulation by transcription factors in response to intrinsic and extrinsic factors. Regarding the study of transcription factors, we discuss some of the promises and pitfalls associated with investigating how individual cells regulate gene expression through modulation of transcription factor activities. Specifically, we discuss four leading experimental approaches, the data that can be obtained from each, and important considerations that investigators should be aware of when drawing conclusions from such data.
NFKB1 and Cancer: Friend or Foe?
Authors: Concetti Julia , Wilson Caroline L.
Published: September 2018

Current evidence strongly suggests that aberrant activation of the NF-κB signalling pathway is associated with carcinogenesis. A number of key cellular processes are governed by the effectors of this pathway, including immune responses and apoptosis, both crucial in the development of cancer. Therefore, it is not surprising that dysregulated and chronic NF-κB signalling can have a profound impact on cellular homeostasis. Here we discuss NFKB1 (p105/p50), one of the five subunits of NF-κB, widely implicated in carcinogenesis, in some cases driving cancer progression and in others acting as a tumour-suppressor. The complexity of the role of this subunit lies in the multiple dimeric combination possibilities as well as the different interacting co-factors, which dictate whether gene transcription is activated or repressed, in a cell and organ-specific manner. This review highlights the multiple roles of NFKB1 in the development and progression of different cancers, and the considerations to make when attempting to manipulate NF-κB as a potential cancer therapy.
Effects of Chitosan Coating Structure and Changes during Storage on Their Egg Preservation Performance
Authors: Xu Dan , Wang Jing , Ren Dan , Wu Xiyu
Published: September 2018

To explore the influences of chitosan coating structure and structure changes during storage on egg preservation, eggs coated by chitosan solution for single time (CS1), two times (CS2), and three times (CS3) were prepared separately and stored with untreated eggs (CK1), eggs washed by water (CK2) and eggs treated by acetic acid solution (CK3) at 25 °C, 80% RH. The weight loss, Haugh unit, yolk index, albumen pH, eggshell morphologies and infrared (FTIR—Fourier Transform Infrared) spectra of all the samples were monitored. CS2 and CS3 presented the lowest weight loss, highest Haugh unit and yolk index, stabilized pH, and the highest thickness of chitosan coating layers (>2 μm) among all the groups, which extended egg shelf life for 20 days longer compared to CK1 and CK2. CS1 with very thin chitosan coating showed similar egg qualities with CK3, which are second only to CS2 and CS3. Furthermore, destructions were found on chitosan coatings during storage as revealed by the eggshell morphologies and FTIR spectra, which caused the quality deterioration of eggs. The results demonstrated that eggs with the thickest coating showed the best qualities during storage, while destructions on coating layers led to the quality drop of eggs.
H2O/D2O Contrast Variation for Ultra-Small-Angle Neutron Scattering to Minimize Multiple Scattering Effects of Colloidal Particle Suspensions
Authors: Otsuki Akira , De Campo Liliana , Garvey Christopher J. , Rehm Christine
Published: September 2018

This study investigated the use of solvent contrast (H2O/D2O ratio) as a means to optimize the ultra-small-angle neutron scattering (USANS) signal. By optimizing the signal, it was possible to reduce the undesirable effects of coherent multiple scattering while still maintaining a measurable scattered intensity. This result will further enable the use of USANS as a probe of the interactions between colloidal particles and their structures within concentrated suspensions as well as particle dispersion/aggregation. As a model system, we prepared silica colloidal particle suspensions at different solid concentrations. USANS curves were measured using the classical Bonse–Hart double crystal diffractometer while varying the scattering length density of the aqueous phase, thus varying the contrast to the silica particles. As a means of assessing the impact of multiple scattering effects on different q-values, we analyzed the scattered intensity at different contrasts at three different q values. The data were then used to determine the match point of the silica particle suspensions from the expected square root dependence of the scattered intensity with solvent composition, to analyze any differences associated with the solid concentration change, and to determine the optimum H2O/D2O ratio in terms of high transmission (TSAS > 80%) and high enough scattering intensity associated with the contrast of the system. Through this investigation series, we confirmed that adjusting the contrast of the solvent (H2O/D2O) is a good methodology to reduce multiple scattering while maintaining a strong enough scattering signal from a concentrated suspension of silica particles for both USANS and rheometric USANS (rheo-USANS) experiments.

The increasing world human population has given rise to the current energy crisis and impending global warming. To meet the international environmental obligations, alternative technological advances have been made to harvest clean and renewable energy. The solar photovoltaics (PV) system is a relatively new concept of clean technology that can be employed as an autonomous power source for a range of off-grid applications. In this study, the dual battery storage system is coupled with a solar PV system and a low voltage grid, benefitting from the feed-in tariff (FIT) policy. The main outcomes of this study are: (I) A novel dual battery storage system for the optimal use of the PV system/energy is proposed; (II) The problem is formulated in the form of a mathematical model, and a cost function is devised for effective cost calculation; (III) An optimal cost analysis is presented for the effective use of PV energy; (IV) real-time data of a solar PV taken from the owner and the demand profile collected from the user is applied to the proposed approach, with United Kingdom (UK) tariff incentives. This system works in a loop by charging one system from the solar PV for one day, and discharging the other system. This model gives certainty that power is exported to the grid when the solar PV generates an excess amount; batteries are utilized during the peak hours, and power is purchased when the demand is not met by the batteries, or when the demand is higher than the generation. This study examined the economic knowledge of solar PV and battery storage systems by considering the FIT incentives.
Semantic and Dweller-Based Decision Support System for the Reconfiguration of Domestic Environments: RecAAL
Authors: Spoladore Daniele , Sacco Marco
Published: September 2018

Researches in the field of ambient assisted living (AAL) have increased in the last ten years, and the paradigms of the smart home have widely spread. Smart homes must consider the health-related issues and the real needs deriving from the ageing of their dwellers. In the smart home, appliances are expected to provide support to the residents, especially when they are characterized by disabilities and/or impairments related to ageing. While most of the AAL solutions presented in literature rely on complex systems and architectures, residents affected by mild or moderate disabilities can take advantage of just a simpler reconfiguration of living environments, i.e., the replacement of certain appliances with others that are able to help them in coping with their limitations. This paper proposes a semantic-based decision support system (DSS), which relies on ontological models, to assist designers in domestic environments’ reconfiguration. The ontology leverages semantic representations of dwellers and domestic environments’ domains of knowledge to foster the adoption of appliances able to help the residents to live independently. The development process of the ontology is presented in detail together with the results deriving from reasoning processes. To ease the reconfiguration of domestic environments, a prototypical application taking advantage of the DSS is presented.

Published: September 2018

In the present paper, the explicit solutions of some local fractional partial differential equations are constructed through the integration of local fractional Sumudu transform and homotopy perturbation such as local fractional dissipative and damped wave equations. The convergence aspect of this technique is also discussed and presented. The obtained results prove that the employed method is very simple and effective for treating analytically various kinds of problems comprising local fractional derivatives.

Tissue-specific gene expression has long been recognized as a crucial key for understanding tissue development and function. Efforts have been made in the past decade to identify tissue-specific expression profiles, such as the Human Proteome Atlas and FANTOM5. However, these studies mainly focused on “qualitatively tissue-specific expressed genes” which are highly enriched in one or a group of tissues but paid less attention to “quantitatively tissue-specific expressed genes”, which are expressed in all or most tissues but with differential expression levels. In this study, we applied machine learning algorithms to build a computational method for identifying “quantitatively tissue-specific expressed genes” capable of distinguishing 25 human tissues from their expression patterns. Our results uncovered the expression of 432 genes as optimal features for tissue classification, which were obtained with a Matthews Correlation Coefficient (MCC) of more than 0.99 yielded by a support vector machine (SVM). This constructed model was superior to the SVM model using tissue enriched genes and yielded MCC of 0.985 on an independent test dataset, indicating its good generalization ability. These 432 genes were proven to be widely expressed in multiple tissues and a literature review of the top 23 genes found that most of them support their discriminating powers. As a complement to previous studies, our discovery of these quantitatively tissue-specific genes provides insights into the detailed understanding of tissue development and function.
GIS-Assisted Prediction and Risk Zonation of Wildlife Attacks in the Chitwan National Park in Nepal

Population growth forces the human community to expand into the natural habitats of wild animals. Their efforts to use natural sources often collide with wildlife attacks. These animals do not only protect their natural environment, but in the face of losing the potential food sources, they also penetrate in human settlements. The research was situated in the Chitwan National Park (CNP) in Nepal, and the aim of this study was to investigate possible geospatial connections between attacks of all kinds of animals on humans in the CNP and its surroundings between 2003 and 2013. The patterns of attacks were significantly uneven across the months, and 89% of attacks occurred outside the park. In total, 74% attacks occurred in the buffer zone forests and croplands within 1 km from the park. There was a strong positive correlation among the number of victims for all attacking animals with a maximum of one victim per 4 km2, except elephant and wild boar. The density of bear victims was higher where the tiger and rhino victims were lower, e.g., in the Madi valley. The data collected during this period did not show any signs of spatial autocorrelation. The calculated magnitude per unit area using the kernel density, together with purpose-defined land use groups, were used to determine five risk zones of wildlife attacks. In conclusion, it was found that the riskiest areas were locations near the forest that were covered by agricultural land and inhabited by humans. Our research results can support any local spatial decision-making processes for improving the co-existence of natural protection in the park and the safety of human communities living in its vicinity.
The Great Debate: General Ability and Specific Abilities in the Prediction of Important Outcomes
Authors: Kell Harrison J. , Lang Jonas W. B.
Published: September 2018

The relative value of specific versus general cognitive abilities for the prediction of practical outcomes has been debated since the inception of modern intelligence theorizing and testing. This editorial introduces a special issue dedicated to exploring this ongoing “great debate”. It provides an overview of the debate, explains the motivation for the special issue and two types of submissions solicited, and briefly illustrates how differing conceptualizations of cognitive abilities demand different analytic strategies for predicting criteria, and that these different strategies can yield conflicting findings about the real-world importance of general versus specific abilities.

Fuel and water contents are inevitable in automotive engine oils. This study intends to investigate the impact of the addition of gasoline (3–20%) and water (1%) on the lubricating performance of synthetic base oil (PAO), with or without an anti-wear additive (ZDDP), for a steel-cast iron contact. Fuel-added PAO showed an increase in the load carrying capacity. Oil electrical conductivity and total acid number (TAN) measurements showed slightly increased conductivity and marginally increased acidity at a higher fuel concentration. In contrast, an increased wear rate, proportional to the fuel concentration, was observed in a prolonged test with constant-loading. Results suggested that the fuel addition is a double-edged sword: reducing the scuffing risk by providing stronger surface adsorption and increasing the sliding wear rate by bringing down the oil viscosity. The PAO-water blend formed an emulsion and resulted in a significantly increased load-carrying capacity, again likely due to the higher polarity and possibly acidity. For the ZDDP-containing PAO, the addition of 1% water and 3% fuel generated 24% and 52% higher wear. The phosphate polymerization level was reduced on the worn surfaces by the introduction of water but the thickness of ZDDP tribofilm was not significantly affected.
Analytical Formula for the Ratio of Central to Minimum Film Thickness in a Circular EHL Contact

Published: September 2018

Prediction of minimum film thickness is often used in practice for calculation of film parameter to design machine operation in full film regime. It was reported several times that majority of prediction formulas cannot match experimental data in terms of minimum film thickness. These standard prediction formulas give almost constant ratio between central and minimum film thickness while numerical calculations show ratio which spans from 1 to more than 3 depending on M and L parameters. In this paper, an analytical formula of this ratio is presented for lubricants with various pressure–viscosity coefficients. The analytical formula is compared with optical interferometry measurements and differences are discussed. It allows better prediction, compared to standard formulas, of minimum film thickness for wide range of M and L parameters.
