Authors: Fatokun J. O. , Nuhu Tsaku. , Ajibola I. K. O.
Published: May 2018

The focus of this research work is the derivation of a class of Adams-like collocation multistep methods of orders not exceeding p=9. Numerical quadrature rule is used to derive steps k= 3,...,8 of the Adams methods. Convergence of each formula derived is established in this paper. As a numerical experiment, the step six pair of the Adams method so derived was used as predictor-corrector pair to solve a non-stiff initial value problem. The absolute errors show an accuracy of o(h7).

Authors: Gaur Kanchan , Shalini Shalini , Singh Satyendra
Published: May 2018

This paper reports electrical conductivity (s) and Seebeck coefficient (s) study on rare-earth nickelates RNiO3 where R = Nd, Sm and Eu in the temperature range 400-1200 K. They have orthorhombic unit cell. The majority charge carriers are holes throughout the measurement. Both s and S variations show three regions. In higher temperature region (Above 1000K) dominant conduction mechanism is intrisic band type whereas below this temperature, hopping of holes from Ni3+ to Ni2+ centres takes place. In lower temperature region, the electrical conductions is taken over by acceptor type impurities. The conduction mechanism is explained on the basis of every band model. Break temperatures as well as mobility have also been evaluated.

Authors: Murhekar G. H. , Raut A. R. , Sonone R. S.
Published: May 2018

The reaction of Pr (III) and Nd (III) metal ions with some substituted pyrazoles, at 0.1M ionic strength and at 30 ± 0.10C in 70% acetone-water mixture and 70% propanol-water mixture have been studied pH-metrically. The data obtained were used to estimate the values of proton-ligand (pK) and metal-ligand (logK) stability constants in different solvents. It is observed that the pK and logK values in 70% propanol-water mixture are grater than in 70% acetone -water mixture. Pr (III) and Nd (III) metal ions formed 1:1 and 1:2 complexes with all the ligands in both solvent medium.
Investigation of Deuteration Effect on Sound Attenuation in Hydrogen Bonded Ferroelectric Crystals
Authors: Deorani S. C. , Singh P. , Yadav M. S.
Published: May 2018

The anomalous ultrasonic attenuation of longitudinal wave propagated in KDP and DKDP have been discussed and calculated near Curie-temperature (Tc) in Para- electric phase in the frequency range 5 to 50 MHz. The attenuation of longitudinal waves is primarily due to a strong interaction with thermally excited phonon in the coupled-soft mode. Temperature and frequency variations of attenuation are discussed. Anharmonicity in the crystal potential is essential to discuss (observe) critical attenuation.
A Thermo Optoacoustic Analysis to Detect Photochemical Reaction of Medicine Ciprofloxacin Hydrochloride
Authors: Krishnankutty K. , Krishnakumar G. , Mohanan S.
Published: May 2018

A new thermo-optoacoustic analysis has been used to detect the photo chemical reactions in medicine ciprofloxacin, a synthetic chemotherapeutic antibiotic of the fluoroquinolone drug class. Certain derived optoacoustic parameters of pure medicine and that exposed to solar radiations have been determined as a function of temperature. Plots of these parameters versus temperature have been made. The nature of variation and the relative shift in the curves for the exposed samples compared with the un exposed ones have been used to study photo chemical reactions. The results have been explained in the light of existing theories and confirmed using UV absorption spectra of the samples.

Published: May 2018

Zinc oxide (ZnO) thin films was deposited on p-silicon (Si) substrate from ammonium zincate bath following a chemical dipping technique called SILAR. Structural characterization by X-ray diffraction (XRD) indicates the formation of polycrystalline single phase ZnO with strong c-axis orientation. I-V characteristic of the p-Si/n-ZnO heterojunction was studied and rectification was observed. The maximum value of forward to reverse current ratio at room temperature was ~15 at 3.0 V. It increases to ~30 at 100oC.
Developments in loaning social assistance: support for mortgage interest in Britain
Authors: Grover Chris
Published: May 2018

Britain's 2015 summer budget introduced a policy extending the use of loans in its social security system. From April 2018 support for mortgage interest will be loaned, rather than granted. Its repayment is to be via a charging order on the homes of benefit recipients and/or from wages when they (re-)enter work. This development is examined in relationship to the use of loans in British social assistance provision. The paper argues that it is consistent with the philosophical underpinnings of loaning social assistance, but it also involves new developments with regard to charging interest and the recovery of the loans.
Charles and Ray Eameses’ museums without walls: Films as exhibition and exhibitions as film
Authors: Ince Catherine
Published: May 2018

This article outlines the intersections between the exhibition and film work of Charles and Ray Eames and the Eames Office, and explores the ways in which film was used to create exhibition environments and vice versa. The Eameses’ desire to transmit ideas to the broadest public generated a concept of the ‘museum without walls’ that found its ultimate expression in the creation of large-scale multi-media and multi-sensory exhibition environments. Their influential practice pioneered new methods of immersive exhibition design, experimented with the use of film as inhabitable exhibit and also as a tool to capture and display cultural subjects and artefacts typically experienced in museum settings. Considering the Eameses’ projects afresh allows us to assess their role in shaping the expansive possibilities of film and the exhibition environment and the challenges of communicating ideas that continue to face museum professionals today.
The modern art of filmmaking: Architecture on-screen at MoMA
Authors: Collard Pete
Published: May 2018

The 1930s saw the Museum of Modern Art (MoMA) in New York become the first museum to include film within its exhibitions of architecture. Although other institutions had offered film screenings for visitors, what set MoMA apart was the manner in which the productions were presented, shown as exhibits within its galleries and displayed alongside photographic reproductions, architectural models and drawings as part of the curatorial narrative. Commissioned in an ad hoc fashion at times and produced to limited budgets, the films brought an emerging form of architectural representation to MoMA at a time when the cultural value of the cinema was still being debated. Under the leadership of Museum Director Alfred J. Barr Jr., the commissioning, curating and collecting of such works became part of a wider movement at MoMA to label the moving image as an art form in its own right.
Installing Islamic Art: Interior Space and Temporal Imagination
Authors: Kadoi Yuka
Published: May 2018

This special issue challenges the anachronistic image of Islamic art galleries that dominated the museum field worldwide during the twentieth century and seeks alternative modes of display to suit current sociopolitical circumstances. Entitled ‘Installing Islamic Art: Interior Space and Temporal Imagination’, the present issue gathers articles dealing with multifaceted topics that address the issue of display and curation of ‘Islamic art’. While the term itself requires further critical reassessment, each author offers an innovative approach and methodological proposition in an effort to recontextualize the current exhibitory trends in the public presentation of material remains from Muslim-majority societies, including the Arab lands, Iran, Turkey, and South Asia. Taken together, this collection of articles reveals many possibilities, rather than limitations, regarding how to thoughtfully showcase Muslim cultural heritage, representing a positive indication of future of curating Islamic art.
Islamic Occultism and the Museum
Authors: Leoni Francesca
Published: May 2018

The exhibition Power and Protection: Islamic Art and the Supernatural, held at the Ashmolean Museum, Oxford, between 20 October 2016 and 15 January 2017, provided the opportunity to reconsider some of the parameters employed in largescale Islamic art exhibitions. The subject of the show – select divinatory and amuletic practices, itself a break from more conventional themes – was explored by adopting a more inclusive and critical approach, drawing evidence from a wide social spectrum and transcending classifications of ‘ethnographic material’ and ‘fine art’. Attention was also given to daily practice, creating a fresh vantage point to reflect on the role and forms of devotion and broader notions of belief. While presenting practices and evidence that many might deem marginal (and that have certainly been marginalized over time), the exhibition ultimately offered a new analytical lens to challenge hierarchies of higher and lower culture, as well as sanctioned versus heterodox religious practices that continue to structure museum presentations and inform public perception of Islamic culture. By exploring the difficulties, achievements, and shortcomings of the project, and by incorporating insights from audience evaluations and impact questionnaires, this article reflects on the range of factors that shape today’s presentations of Islamic art and culture in the museum, as well as on the unprecedented challenges faced by specialists of Islam in western institutions at this critical historical moment. Furthermore, by considering the exhibition in the context of the current, revitalized museological interest in religions, it offers a contribution to the broader debate about religious objects in secular institutions and the need to reconcile multiple views and expectations.

Direito e proteção à privacidade em códigos deontológicos de jornalismo
Authors: Christofoletti Rogério , Gaia Giulia Oliveira
Published: May 2018

A privacidade já não é mais o que era antes. As transformações culturais decorrentes dos avanços tecnológicos mais recentes têm ajudado a redefinir os contornos do mundo reservado da intimidade. Câmeras espalhadas por toda parte, dispositivos móveis cada vez mais populares e capazes de captar qualquer movimento, e sistemas de monitoramento, rastreamento e vigilância massiva fazem com que “estar só” seja quase impossível nos dias atuais. Ao mesmo tempo, bilhões de pessoas exibem-se nas redes sociais e a mídia aperta o cerco para satisfazer o direito à informação. Neste contexto de erosão da vida íntima, avaliamos como o tema da privacidade é tensionado em vinte códigos deontológicos do jornalismo. Analisamos como o assunto é tratado, com que profundidade e que recomendações são dadas aos profissionais para atender a esse direito. Os resultados apontam para superficialidade, desatualização e insuficiência dos códigos para tratar da questão.

Published: May 2018

Studying elusive species of conservation concern might be difficult for technical and ethical reasons. However, censuses can be based on the observation of activity indices. When coupled to non-invasive genetic methods this approach can provide extremely precise information about population size, individual movements and diseases. However, the design of optimal sampling is dependent on a knowledge on group distribution and possible variations of detectability of index targets. The aim of this study was to document the distribution of Yunnan snub-nosed monkey indices in space and time in that perspective. Based on transects carried out across the range of a fed population and on counts along the trail across the range of a wild group, we show that 2–3 day stays of a group in a place of some hectares were sufficient to get an homogeneous distribution of indices. Furthermore, the number of indices found were dependent on both pig presence and season. On the other hand, on a large scale of 100 km2 indices were spatially distributed as nested clusters. Indices distribution indicated a strong preference towards southern slopes and altitudes ranging between 2900 and 3400 m. Those observations pinpoint the importance of considering spatial scale to organise sampling designed to estimate population distribution.
Solid-solid intercalation and optical properties of VO-8-hydroxyquinoline decoration of layered silicate magadiite
Authors: Zhang Yifu
Published: May 2018

Coordination of vanadyl (VO2+) ions with 8-hydroxyquinoline (8Hq) in the interlayer space of layered silicate magadiite (mag) was realized by solid-solid intercalation. Composition, structure and morphology of this compound were studied by X-ray diffraction (XRD), Fourier-transform infrared spectrometry (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray spectrometry (EDS), X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The obtained results indicate that the basal spacing of decorated mag increased after intercalation and suggest that VO-8Hq decorated into the interlayer of mag (VO-mag-8Hq) was successfully synthesized for the first time. Optical properties of VO-mag-8Hq were studied by ultraviolet-visible (UV-Vis) and photoluminescence spectroscopy (PL). The findings reveal that VO-8Hq complexes in the interlayer space exhibit extraordinary fluorescence properties and the confined space of mag influences the optical properties of VO-8Hq complexes.
Local temperature rise during the electron beam characterization Calculation model for the AlxGa1-xN at low dimensions
Authors: Leghrib Lazhar , Nouiri Abdelkader
Published: May 2018

During the characterization by electron beam techniques including scanning electron microscope (SEM) and cathodoluminescence at low dimensions, some undesirable phenomena (unwanted effects) can be created, like the thermal effects (or electron beam damage), and these effects can damage the sample. This limits the information one can get from a sample or reduces image spatial resolution. In order to understand these effects, significant efforts have been made but these studies focused on the thermal properties, without a detailed study of the causes of nanoscale heating in the bulk of samples during the SEM-characterization. Additionally, it is very difficult to measure experimentally the heating because there are many variables that can affect the results, such as the current beam, accelerating energy, thermal conductivity and size of samples. Taking into account all the factors and in order to determine the local temperature rise during the electron beam characterization of AlGaN at low dimensions, we have used a hybrid model based on combined molecular dynamics and Monte Carlo calculation of inelastic interaction of electrons with matter to calculate the temperature elevation during the SEM-characterization which can be taken into account during the characterization of AlGaN at low dimension by electron beam techniques.

Published: May 2018

Biosensor design is important to bioanalysis yet challenged by the restricted target accessibility at the biomolecule-surface (bio-surface). The last two decades have witnessed the appearance of various “art-like” DNA nanostructures in one, two, or three dimensions, and DNA nanostructures have attracted tremendous attention for applications in diagnosis and therapy due to their unique properties (e.g., mechanical flexibility, programmable control over their shape and size, easy and high-yield preparation, precise spatial addressability and biocompatibility). DNA nanotechnology is capable of providing an effective approach to control the surface functionality, thereby increasing the molecular recognition ability at the biosurface. Herein, we present a critical review of recent progress in the development of DNA nanostructures in one, two and three dimensions and highlight their biological applications including diagnostics and therapeutics. We hope that this review provides a guideline for bio-surface engineering with DNA nanostructures.

Published: May 2018

In this study, the writer as a teacher model, tried to explore: (1) the advantages and disadvantages of lesson study applied in a theoretical subject class; and (2) the effectiveness of it for students' learning outcomes. It was conducted in a class called Introduction to Linguistics with 30 students. There were four cycles and four colleagues who took part as the observers. In each cycle, she did PLAN, DO, and SEE. Then, descriptive analysis was used to elaborate teachers‘ professionalism and students‘ learning outcomes through observation sheets, discussion, and test. The result shows that there are some benefits, i.e. (1) the teacher can prepare her lesson plans and teaching media more carefully; (2) she can conduct her class more confidently and professionally; (3) she can get evaluation about her teaching process after her class ends; (4) the students can be more active and study more seriously; and(5) they can achieve better scores compared to other classes which don‘t use lesson study. However, there are also some disadvantages, e.g. (1) the teacher needs more time to prepare her lesson plans and teaching media; and (2) some students may feel depressed because of the observers‘ attendance.

OBJECTIVES:

The earned income tax credit (EITC), refundable monies for America’s working poor, is associated with improved child health. Yet, 20% of eligible families do not receive it. We provided free tax preparation services in clinics serving low-income families and assessed use, financial impact, and accuracy.

METHODS:

Free tax preparation services (“StreetCred”) were available at 4 clinics in Boston in 2016 and 2017. We surveyed a convenience sample of clients (n = 244) about experiences with StreetCred and previous tax services and of nonparticipants (n = 100; 69% response rate) and clinic staff (n = 41; 48% response rate) about acceptability and feasibility.

RESULTS:

A total of 753 clients received $1 619 650 in federal tax refunds. StreetCred was associated with significant improvement in tax filing rates. Of surveyed clients, 21% were new filers, 47% were new users of free tax preparation, 14% reported new receipt of the EITC, and 21% reported new knowledge of the EITC. StreetCred had high client acceptability; 96% would use StreetCred again. Families with children were significantly more likely to report StreetCred made them feel more connected to their doctor (P = .02). Clinic staff viewed the program favorably (97% approval).

CONCLUSIONS:

Free tax services in urban clinics are a promising, feasible financial intervention to increase tax filing and refunds, save fees, and link clients to the EITC. With future studies, we will assess scalability and measure impact on health. StreetCred offers an innovative approach to improving child health in primary care settings through a financial intervention.

Published: May 2018

RESUMO No Brasil, 85% das Bignoniaceae são representadas pela tribo Bignonieae, caracterizada pelo hábito trepador e arbustivo escandente. No Parque Estadual do Rio Doce (PERD), um dos últimos remanescente de Mata Atlântica em Minas Gerais, foram registradas 37 espécies dessa tribo. O presente estudo teve como objetivos: descrever a distribuição vertical das espécies de Bignonieae do PERD; reconhecer os padrões fenológicos de floração apresentados por elas; e associar os padrões morfológicos de corola e síndromes florais já estabelecidos com aqueles encontrados no PERD. As 37 espécies de Bignonieae foram observadas periodicamente, no período de 15 meses e 32 visitas. A distribuição vertical ocorreu em três estratos: dossel (75,7%), entre-copa (16,2%) e sub-bosque (8,1%), significando que 24,3% dessas espécies difundiram-se para outros nichos ecológicos, além do estrato superior da mata. Os padrões fenológicos de floração foram: floração maciça em 40,6% das espécies, várias florações maciças em 21,6%, estacionário modificado em 16,2% e cornucópia em 13,5%. O tipo de corola Anemopaegma foi o mais representativo (44,1% das espécies estudadas), seguido do tipo Stizophyllum e Cydista (14,7%, cada), Pithecoctenium e Pyrostegia (11,8%, cada) e Tynnanthus (2,9%). Associando a morfologia da corola ao possível polinizador, verificou-se que 83,8% das espécies apresentam tipos florais relacionados à melitofilia, reforçando a importância das Bignonieae na manutenção de abelhas médias e grandes em florestas tropicais.

A Facile HPLC-PDA Method for Simultaneous Determination of Paracetamol, Methyl Paraben, Sunset Yellow and Carmosine in Oral Suspensions
Authors: Dinç Zor Şule , Aksu Dönmez Özlem
Published: May 2018

In the present study, a simple, fast
and accurate HPLC-PDA method was developed for the simultaneous determination
of paracetamol (PAR), methylparaben (MP), sunset yellow (SSY) and carmoisine
(CAR) in oral suspensions. The concentrations of colorants are less than with
respect to those of active ingredient and this variation makes process of
analysis toublesome. In the developed HPLC method, efficient chromatographic
separation was achieved using reversed phase C18 column (4.6 mm x 150 mm x 5 μm
particle size) and phosphate buffer solution (pH = 6.5)-acetonitrile mobile
phase with a flow rate of 1.6 mL/min in the gradient mode. The eluents were
monitored via a PDA detector at 300, 254 and 230 nm. The mean retention times of
SSY, PAR, CAR and MP were found to be 1.58, 2.15, 3.81 and 4.42, respectively.
The proposed method was validated in accordance with ICH guidelines and it was
seen that the method met all requirements in terms of linearity, precision,
accuracy and selectivity. The developed method was successfully applied for
simultaneous determination of the studied compounds in two commercial oral
suspension samples.

Authors: Armentani Enrico , Caputo Francesco , Esposito Luca , Citarella Roberto
Published: May 2018

In this paper, a multibody calculation methodology has been applied to the vibration analysis of a 4-cylinder, 4-stroke, turbocharged diesel engine, with a simulation driven study of the angular speed variation of a crankshaft under consideration of different modeling assumptions. Moreover, time dependent simulation results, evaluated at the engine supports, are condensed to a vibration index and compared with experimental results, obtaining satisfactory outcomes. The modal analysis also considers the damping aspects and has been conducted using a multibody model created with the software AVL/EXCITE. The influence of crankshaft torsional frequencies on the rotational speed behavior has been evaluated in order to reduce the vibration phenomena.

Published: May 2018

This article is an evaluation result of the program implementation of TBM “Talenta Azzura” at Jogoyudan, Jetis, Jogyakarta. The evaluation was aimed at (1) community’s interest on the program, (2) community as members, (3) managers and attendants, (4) support systems, (5) fund, (6) management systems, (7) services, and (8) usefulness either for its members or the community. Subjects of the evaluation were members as well as the managers and staffs of TBM “Talenta Azzura”. Data were gathered through techniques of observation, interviews, questionnaires, and documentation. The analysis was conducted by using SPSS 10,00 for Window (statistical program), it was descriptive. The Evaluation model applied was Stufflebeam’s CIPP (context, inputs, process, and product). The evaluation results indicate that community has diversed socio-economic background as shown by the total income of parents ranges from Rp. 500.000,- to Rp. 750.000,-/month. Most members’ parents are vendors. The questionnaires drew a conclusion that community’s support quality is mediocre yet no rejection or feelings against the program. Further, conclusions drawn upon evaluation model are (1) inputs are members who age between 3 – 12 years old, mostly higlymotivated girls, (2) there are two categories of the managers and staffs, permanent managers or attendants are from the community itself and there are some part-time attendants. Somehow the TBM gets little support for services and lack of fund. Results from questionnaires regarding process show low quality of management and services though data gathered regarding mentoring program indicate meaningfulness of the program for members and the community. In regards of product, results from questionnaires,interviews and observation picture that the existence of TBM is advantageous either for members or the community.
