CoFe/γ-Al2O3 Catalyst for the Hydrotreatment of Fatty Acid Methyl Esters (FAME)
Authors: Hari Thushara Kandaramath , Yaakob Zahira 
Published: May 2015

Abstract
Catalytic hydroprocessing of fatty acid methyl esters (FAME) is a promising route for enhancing the properties to cover their disadvantages to replace conventional motor fuel. Non-sulfided CoFe/γ-Al2O3 catalyst was synthesized for the hydrotreatment of FAME derived from Jatropha oil. Straight-chain alkanes in the range C15–C18 were the major products. A maximum FAME conversion of 82.56% and diesel selectivity of 81.2% were obtained at 400 °C and 2 MPa. Effect of the reaction temperature and reaction time on the FAME conversion and diesel selectivity were studied. Fe incorporation facilitated the cobalt oxide reduction by H2 spill over and cobalt oxide dispersion, which facilitate C–O bond activation and breaking.

Published: May 2015

Abstract
A facile one-pot method for synthesizing different morphologies of PdCu nanocrystals (NCs) has been introduced. The morphologies of PdCu NCs can be controlled by tuning the amount of the single capping ligand of triphenylphosphine (TPP) in an organic solvent medium. Highly structured cubic, sphere, and sphere-like PdCu NCs were obtained in a sufficient amount, a small amount, and the absence of TPP, respectively. It is found that these PdCu NCs exhibit efficient catalytic activities for formic acid oxidation (FAO). The mass activities of these carbon-supported NCs follow the order of sphere PdCu/C &gt; sphere-like PdCu/C &gt; cubic PdCu/C at a potential of 0.2 V (vs. SCE). Among these NCs, the sphere PdCu/C catalyst exhibits the highest FAO activity, which is 1.7 times larger than that of commercial Pd/C catalyst at 0.2 V. Our results show that the surfactant loading can play a key role in the shape-controlled synthesis of PdCu nanocrystals for FAO.

Abstract
Rhodium-catalyzed direct coupling of benzothioamides with alkenes proceeds smoothly involving ortho-C–H bond cleavage. The thioamides also couple with alkynes under similar conditions accompanied by desulfurization and C–N bond cleavage to produce indenone derivatives.
About the Role of Personal Hearing Protection from Harmful Effects of Industrial Noise in Special Assessment of Working Condition
Authors: Готлиб  , Gotlib YAkov , Алимов  , Alimov N. 
Published: May 2015

Personal hearing protection is a simple and effective way to improve labour conditions of workers when exposed to high
noise levels. Protective properties of earmuffs and earplugs should be considered when establishing classes of working
conditions equally to all known technical, construction and organizational methods of noise reduction. In this case,
procedures for the usage of personal noise protective equipment should be based on actually achieved efficiencies of these
products, established by the modern standardized test methods.

Published: May 2015

The influence of the circuitry of the hybrid power plant short and medium haul aircraft on their fuel efficiency and
environmental characteristics have been investigated. Directions of improvement of traditional patterns of power plants of
aircraft on the example of PD-14 engine were analyzed. It has been shown that the use of turbojet engines and traditional
schemes operating on aviation kerosene, will not allow to fulfill the demands made by the International Civil Aviation
Organization (ICAO) to perspective plane 2025–2035. The analysis of the three schemes hybrid propulsion systems has
been performed. It has been shown that using the presented hybrid propulsion systems of alternative fuels can reduce CO2
emissions by 19% to 20% compared with conventional turbojet engines, which run on kerosene TS-1. It has been shown
that this fuel efficiency is increased by 2–3%, and the total mass of the power plant increases of 6 to 16%.

Published: May 2015

Introduction: The use of clinically derived data from electronic health records
(EHRs) and other electronic clinical systems can greatly facilitate clinical research as
well as operational and quality initiatives. One approach for making these data
available is to incorporate data from different sources into a joint data warehouse.
When using such a data warehouse, it is important to understand the quality of the data.
The primary objective of this study was to determine the completeness and concordance of
common types of clinical data available in the Knowledge Program (KP) joint data
warehouse, which contains feeds from several electronic systems including the
EHR.Methods: A manual review was performed of specific data elements for 250 patients
from an EHR, and these were compared with corresponding elements in the KP data
warehouse. Completeness and concordance were calculated for five categories of data
including demographics, vital signs, laboratory results, diagnoses, and
medications.Results: In general, data elements for demographics, vital signs, diagnoses,
and laboratory results were present in more cases in the source EHR compared to the KP.
When data elements were available in both sources, there was a high concordance. In
contrast, the KP data warehouse documented a higher prevalence of deaths and medications
compared to the EHR.Discussion: Several factors contributed to the discrepancies between
data in the KP and the EHR—including the start date and frequency of data feeds updates
into the KP, inability to transfer data located in nonstructured formats (e.g., free
text or scanned documents), as well as incomplete and missing data variables in the
source EHR.Conclusion: When evaluating the quality of a data warehouse with multiple
data sources, assessing completeness and concordance between data set and source data
may be better than designating one to be a gold standard. This will allow the user to
optimize the method and timing of data transfer in order to capture data with better
accuracy.
The Vocal Tract Organ and the Vox Humana organ stop
Authors: Howard David M. 
Published: May 2015

Abstract
The Vocal Tract Organ is a new musical instrument that consists of three-dimensional (3D)-printed vocal tracts (throat and mouth) for individual vowels sitting on loudspeakers to enable static vowel sounds to be produced. The acoustic excitation from the loudspeakers is a synthesized version of the typical waveform produced by the vibrating human vocal folds during pitched sounds, which enables the instrument to be played from a keyboard. The synthesis engine is implemented in Pure Data. This article describes the implementation of the Vocal Tract Organ, how it has been used musically to date, and the similarities and differences between it and the Vox Humana pipe organ stop. It is suggested that the Vocal Tract Organ will become an instrument in its own right and that it could be used as a direct replacement for the Vox Humana organ stop, given that its acoustic output is a much closer representation of the human vocal output than that from a Vox Humana organ pipe. In addition, the author makes use of the 3D-printed tracts in vocal and choral workshops as well as degree-level music technology education.
Graduate meets employer – a model for embedding industry professional involvement in the development and assessment of student portfolios
Authors: Thorley Mark 
Published: May 2015

Abstract
The benefit of higher education institutions working with industry professionals has received significant attention in literature and policy. Despite this, the challenges in institutions themselves, and the nature of the music industry makes this concept challenging to manage. In response to this, a project was funded by the Higher Education Academy for Coventry University to examine a model for embedding the involvement of industry professionals in the development and assessment of Music Technology student portfolios. This article explains the background, the rationale, realization and outcomes of the project. First, it outlines the issues of employability within music and creative industries courses as reflected in the literature. It then examines the contextual challenges of the music industry and higher education. It continues by describing how the project embedded industry professionals in student portfolio development and assessment. Finally, it outlines the outcomes of the project, its implications and the key risk factors to its implementation in other disciplines and institutions.
Double dipping in hybrid open access – chimera or reality?
Authors: Mittermaier Bernhard 
Published: May 2015

Abstract
The pros and cons of hybrid open access are heavily disputed. A main point of discussion is whether ‘double dipping’ takes place, i.e. paying twice to publish and read the same article. To prove publishers’ assertions that they do not double dip, a survey was conducted of 24 publishers with detailed questions about their pricing policy using concrete examples. The outcome is quite sobering: the results range from partial double dipping to full double dipping, and in no instance did a ‘no double-dipping’ policy mean that no double dipping takes place.

<p>Parallel computing and steadily increasing computation speed have led to a new tool for analyzing multiple datasets and datatypes: fitting several datasets simultaneously. With this technique, physically connected parameters of individual data can be treated as a single parameter by implementing this connection directly into the fit. We discuss the terminology, implementation, and possible issues of simultaneous fits based on the Interactive Spectral Interpretation System (ISIS) X-ray data analysis tool. While all data modeling tools in X-ray astronomy in principle allow data to be fitted individually from multiple data sets, the syntax used in these tools is not often well suited for this task. Applying simultaneous fits to the transient X-ray binary GRO J1008–57, we find that the spectral shape is only dependent on X-ray flux. We determine time independent parameters e.g., the folding energy E<sub>fold</sub>, with unprecedented precision.</p>
LED Based Spectrophotometer can compete with conventional one

Published: May 2015

Spectrophotometers are the common devise used for blood analysis. These analyses are simply optioned from the transmittance of monochromatic light through a blood sample. It disperses their light sources by different techniques; the simplest one is the use of interference filters in front of broad-band light source. As Interference bandpass filters are relatively inexpensive wavelength selectors. Interference filters that allow transmission of a predetermined wavelength while rejecting or blocking other wavelengths are widely used in instrumentation for clinical chemistry. On the other hand, the lights emitting diodes (LEDs) emits a specified band and have a wide selection options. An economic device based on LEDs (LED based spectrometer) is explained in this work. Instead of the wide spectrum light source and filters (commercial spectrophotometer), The LED based spectrophotometer is calibrated with standard solutions, and its measurement results is compared with the Mindray BS-200 Chemistry Analyzer (commercial spectrophotometer). The comparison shows acceptable results between both spectrophotometers with maximum error 2.33%. The errors can be reduced by applying more fining alignment. Another benefit of the new designee is to minimize testing costs.
Passado histórico, presente historiográfico: considerações sobre "História e Estrutura" de Michel de Certeau
Authors: Ohara João Rodolfo Munhoz 
Published: May 2015

No ensaio “História e Estrutura”, Michel de Certeau pensa o ofício do historiador como um problema, um conjunto de procedimentos que merece uma análise cuidadosa. Nesse texto, Certeau discute a tensão colocada no enfrentamento com o Outro, no instante em que o historiador encontra a alteridade do que passou, e mais especificamente os efeitos do pensamento dito “estruturalista” sobre tal tensão. Pensamos que muitas das considerações de Certeau ainda são relevantes para refletir sobre a escrita da história e a relação dos homens com o tempo neste período que se diz de crise epistemológica. Assim, nosso trabalho busca explorar os apontamentos de Certeau e articulá-los ao que consideramos ser um projeto maior do autor, a saber, a crítica do fazer historiográfico enquanto prática, desenvolvida alhures.
Efficacy of inhaled corticosteroids for patients with asthma: a descriptive review of randomized controlled trials
Authors: Alabousi Mostafa , Alabousi Abdullah , Ambeault Natalie , Riva John 
Published: May 2015

Objective: To evaluate the efficacy of inhaled corticosteroids (ICS) in patients with asthma based on changes in sputum eosinophil counts, through a review of relevant randomized controlled trials (RCTs).Methods: Studies were retrieved from MEDLINE, EMBASE, the SYSTEM FOR INFORMATION ON GREY LITERATURE, and the INSTITUTE FOR SCIENTIFIC INFORMATION from February 1, 2003 to February 1, 2013 based on a comprehensive search strategy. Articles were screened through two stages: title and abstract; and full-text screening. RCTs enrolling patients with asthma, testing an ICS intervention, and reporting outcomes on changes in sputum eosinophil counts pre- and post-intervention were included. Following screening, data extraction, and quality appraisal, a descriptive synthesis of trials was conducted.Results: The search strategy retrieved 447 articles, of which 66 articles underwent full-text screening, resulting in 37 RCTs that met the inclusion criteria for this review. The articles were stratified according to the type of ICS: budesonide, fluticasone propionate, ciclesonide, beclomethasone dipropionate, and mometasone. Across trials, 9 of 16 budesonide, 5 of 14 fluticasone propionate, 4 of 9 of nine ciclesonide, 2 of 4 beclomethasone dipropionate, and 1 of 2 mometasone interventions demonstrated a statistically significant (p < 0.05) reduction in sputum eosinophil counts.Conclusion: This study detected differences between ICS treatments however the clinical relevance is uncertain. There is insufficient evidence to suggest the superiority of one ICS treatment over another. Further research needs to be conducted to evaluate the relative impact of ICS products upon eosinophil counts, as well as in clarifying what quantitative level of change in baseline eosinophil counts is required to observe a change in symptom improvement and disease control.
Seasonal Occurence of Food and Feeding Habit of Labeo bata(Hamilton) (Cypriniformes : Cyprinidae)
Authors: Joadder Md. Abdur Razzaq 
Published: May 2015

Food and feeding habits of fishes have a great significance in aquaculture practices. It helps to select such species of fishes for culture which will utilize all the available potential food of the water bodies without much competition with one another but will live in association with other fishes. This paper deals with the feeding intensity and food habits of L. bata . Food and feeding habit of freshwater minor carp Labeo bata (120 to 250 mm total length) were studied. The fish is a herbivore, feeding mainly on algae (22.32 %), higher plant parts (31.26 %), protozoans (7.42 %), crustaceans (15.33 %), insects (3.56 %), muds, sand, debris and detritus (16.32 %) and unidentified food materials (3.99%).Journal of Science Foundation, 2014;12(1):7-15
On the influence of “non‐Redfield” dissolved organic nutrient dynamics on the spatial distribution of N2 fixation and the size of the marine fixed nitrogen inventory
Authors: Somes Christopher J. , Oschlies Andreas 
Published: May 2015

AbstractDissolved organic nitrogen (DON) and phosphorus (DOP) represent the most abundant form of their respective nutrient pool in the surface layer of the oligotrophic oceans and play an important role in nutrient cycling and productivity. Since DOP is generally more labile than DON, it provides additional P that may stimulate growth of nitrogen‐fixing diazotrophs that supply fixed nitrogen to balance denitrification in the ocean. In this study, we introduce semirecalcitrant components of DON and DOP as state variables in an existing global ocean‐atmosphere‐sea ice‐biogeochemistry model of intermediate complexity to assess their impact on the spatial distribution of nitrogen fixation and the size of the marine fixed nitrogen inventory. Large‐scale surface data sets of global DON and Atlantic Ocean DOP are used to constrain the model. Our simulations suggest that both preferential DOP remineralization and phytoplankton DOP uptake are important “non‐Redfield” processes (i.e., deviate from molar N:P = 16) that need to be accounted for to explain the observed patterns of DOP. Additional non‐Redfield DOP sensitivity experiments testing dissolved organic matter (DOM) production rate uncertainties that best reproduce the observed spatial patterns of DON and DOP stimulate additional nitrogen fixation that increases the size of the global marine fixed nitrogen inventory by 4.7 ± 1.7% compared to the simulation assuming Redfield DOM stoichiometry that underestimates the observed nitrogen inventory. The extra 8 Tg yr−1 of nitrogen fixation stimulated in the Atlantic Ocean is mainly responsible for this increase due to its large spatial separation from water column denitrification, which buffers any potential nitrogen surplus in the Pacific Ocean. Our study suggests that the marine fixed nitrogen budget is sensitive to non‐Redfield DOP dynamics because access to the relatively labile DOP pool expands the ecological niche for nitrogen‐fixing diazotrophs.

AbstractThe twin Van Allen Probes spacecraft witnessed a series of lobe encounters between 0200 and 0515 UT on 14 November 2012. Although lobe entry had been observed previously by other spacecraft, the two Van Allen Probe spacecraft allow us to observe the motion of the boundary for the first time. Moreover, this event is unique in that it consists of a series of six quasi‐periodic lobe entries. The events occurred on the dawn flank between 4 and 6.6 local time and at altitudes between 5.6 and 6.2 RE. During the events Dst dropped to less than −100nT with the IMF being strongly southward (Bz = −15nT) and eastward (By = 20 nT). Observations by LANL‐GEO spacecraft at geosynchronous orbit also show lobe encounters on the dawn and dusk flanks. The two spacecraft configuration provides strong evidence that these periodic entries into the lobe are the result of local expansions of the OCB propagating from the tail and passing over the Van Allen Probes. Examination of pitch angle binned data from the HOPE instrument shows spatially large, accelerated ion structures occurring near simultaneously at both spacecraft, with the presence of oxygen indicating that they have an ionospheric source. The outflows are dispersed in energy and are detected when the spacecraft are on both open and closed field lines. These events provide a chance to examine the global magnetic field topology in detail, as well as smaller‐scale spatial and temporal characteristics of the OCB, allowing us to constrain the position of the open/closed field line boundary and compare it to a global MHD model using a novel method. This technique shows that the model can reproduce a periodic approach and retreat of the OCB from the spacecraft but can overestimate its distance by as much as 3 RE. The model appears to simulate the dynamic processes that cause the spacecraft to encounter the lobe but incorrectly maps the overall topology of the magnetosphere during these extreme conditions.

AbstractSulfate aerosols simulated by an aerosol module coupled to the Nonhydrostatic Icosahedral Atmospheric Model (NICAM) at a spatial resolution (220 km) widely used by global climate models were evaluated by a comparison with in situ observations and the same aerosol module coupled to the Model for Interdisciplinary Research on Climate (MIROC) over East Asia for January, April, July, and October 2006. The results indicated that a horizontal gradient of sulfate from the source over China to the outflow over Korea‐Japan was present in both the simulations and the observations. At the observation sites, the correlation coefficients of the sulfate concentrations between the simulations and the observations were high (NICAM: 0.49–0.89, MIROC: 0.61–0.77), whereas the simulated sulfate concentrations were lower than those obtained by the observation with the normalized mean bias of NICAM being −68 to −54% (all), −77 to −63% (source), and −67 to −30% (outflow) and that of MIROC being −61 to −28% (all), −77 to −63% (source), and −60 to +2% (outflow). Both NICAM and MIROC strongly underpredict surface SO2 over China source regions and Korea‐Japan outflow regions, but the MIROC SO2 is much higher than NICAM SO2 over both regions. These differences between the models were mainly explained by differences in the sulfate formation within clouds and the dry deposition of SO2. These results indicated that the uncertainty of the meteorological and cloud fields as well as the vertical transport patterns between the different host climate models has a substantial impact on the simulated sulfate distribution.
