Geminate timing in Lebanese Arabic: the relationship between phonetic timing and phonological structure
Authors: Khattab Ghada , Al-Tamimi Jalal 
Published: May 2014

AbstractThis study investigates medial gemination patterns in Lebanese Arabic (LA). It offers an account of the duration patterns of quantity distinction for vowels and consonants in LA by using the most comprehensive dataset for this variety, and for Arabic in general, so far in terms of the number of speakers (20), the consonant types examined (24), the inspection of vowels preceding and following the consonant in durational analyses, and the inclusion of male and female speakers. The main aim is to show correspondence between phonetic timing in LA and phonological accounts of syllabic structure that are based on moraic weight (Hayes 1989; Broselow 1995; McCarthy and Prince 1995). The study extends predictions of mora-sharing in disyllables with medial clusters that are preceded by a long vowel (e.g., /ˈmaal.ħa/ ‘salty-FEM-SG’) to comparable syllables with a medial geminate (e.g., /ˈmaal.la/ ‘bored-FEM-SG’), which have not been investigated in Arabic before. It shows that vowel shortening preceding medial geminates affects phonologically long but not short vowels, downplaying the commonly referred to closed-syllable shortening effect as the main reason for this phenomenon (Maddieson 1997). Instead, an account based on the interface between phonetic and phonological effects on compensatory vowel shortening offers better predictions.

AbstractA non-invasive method for the detection of glucose is sought by millions of diabetic patients to improve personal management of blood glucose over a lifetime. In this work, the synergistic advantage of combining plasmonic interferometry with an enzyme-driven dye assay yields an optical sensor capable of detecting glucose in saliva with high sensitivity and selectivity. The sensor, coined a “plasmonic cuvette,” is built around a nano-scale groove-slit-groove (GSG) plasmonic interferometer coupled to an Amplex–red/Glucose–oxidase/Glucose (AR/GOx/Glucose) assay. The proposed device is highly sensitive, with a measured intensity change of 1.7×105%/m (i.e., one order of magnitude more sensitive than without assay) and highly specific for glucose sensing in picoliter volumes, across the physiological range of glucose concentrations found in human saliva (20–240 μm). Real-time glucose monitoring in saliva is achieved by performing a detailed study of the underlying enzyme-driven reactions to determine and tune the effective rate constants in order to reduce the overall assay reaction time to ∼2 min. The results reported suggest that by opportunely choosing the appropriate dye chemistry, a plasmonic cuvette can be turned into a general, real-time sensing scheme for detection of any molecular target, with high sensitivity and selectivity, within extremely low volumes of biological fluid (down to femtoliters). Hereby, we present the results on glucose detection in artificial saliva as a notable and clinically relevant case study.

Catalytic chemical processes for biomass conversion: Prospects for future biorefineries
Authors: Luque Rafael 
Published: May 2014

AbstractBiomass is a renewable and abundant feedstock that is poised to become a future alternative to petroleum as the understanding and technology surrounding catalytic biomass conversion and biorefineries progresses. A relevant research avenue explored in recent years deals with biomass deconstruction into simpler compounds (platform chemicals) by overcoming its recalcitrant and complex structure and subsequently converting these building blocks into value-added chemicals, fuels and materials in a similar way to that of current refineries. This contribution is aimed at providing a short overview of biomass processing chemistry by illustrating some relevant examples of catalytic strategies for biorefineries.

AbstractThe aim of this study was to synthesize in high product yield of anisotropic core-shell Fe3 O4@Au magnetic nanoparticles and to investigate the effect of the immunomagnetic separation (IMS) volume on the capture efficiency. For these purposes and for the first time, we synthesized polyhedral magnetic nanoparticles composed of Fe3 O4 core Au shell. To synthesize magnetic gold anisotropic core-shell particles, the seed-mediated synthetic method was carried out. By choosing an appropriate amount of iron particles and growth solution the fine control of the seed-mediated approach is enabled. This led to the high product yield of anisotropic nanoparticles. The magnetic separation of these nanoparticles was easily accomplished, and the resulting nanoparticles were characterized with transmission electron microscopy (TEM), ultraviolet visible spectroscopy (UV–vis), near edge absorption fine structure (NEXAFS) spectroscopy, and X-ray diffraction (XRD). Additionally, the magnetic properties of the nanoparticles were examined. The magnetic nanoparticles (MNPs) were modified with antibody and interacted with Escherichia coli (E. coli). The high capture efficiency between the magnetic nanoparticles and E. coli is evidenced by SEM images. The capture efficiency decreases with an increase of volumes, and the highest capture efficiency was observed for E. coli in an experiment volume of 100 μL for magnetic nanoparticles. The percentage of captured E. coli for polyhedral nanoparticles was found to be approximately 95 % and for spherical nanoparticles 88 %, respectively.

Published: May 2014

AbstractGlycerol acetals were prepared from glycerol and aromatic aldehydes (benzaldehyde, anisaldehyde, or furfural) using a solid acid (Amberlyst-15) catalyst. The acetals show promising antioxidant activity using the DPPH test with the glycerol/anisaldehyde acetal showing the best antioxidant properties, attributed to the additional radical stabilization by the electron-releasing methoxy group. The acetals formed have a wide range of potential industrial applications particularly enabling integration of the biodiesel manufacturing chain.

Published: May 2014

AbstractThe present study focuses on synthesis of SAPO-34 zeolite membrane on the surface of CuO–ZnO–Al2O3 (CZA) catalyst particles to form CZA@SAPO-34 core@shell structured catalyst. In contrast to the traditional support of porous alumina, CZA catalyst particles have a relatively brittle surface, which leads to a big challenge to coat SAPO-34 zeolite membrane on their surface. Moreover, the hydrothermal synthesis of SAPO-34 zeolite membrane is carried out under weakly alkaline condition at 200 °C for hours, which causes part of the surface of CZA to be fragmented. To overcome these shortcomings, the intermediate layer of alumina is introduced to the surface of the CZA particles and acts as a barrier to the high-temperature hydrothermal and alkaline condition. It also takes as a transition to enhance SAPO-34 zeolite seeds adherence to the surface of CZA particles. With the help of an alumina layer, a continuous and dense zeolite membrane has been obtained on the surface of CZA particles. The prepared core@shell structured catalyst has better selectivity in CO hydrogenation for producing light hydrocarbons because of the synergetic effects between the membrane and core catalyst.
Uranium toxicity and chelation therapy
Authors: Lawrence Glen D. , Patel Kamalkumar S. , Nusbaum Aviva 
Published: May 2014

AbstractUranium toxicity has been a concern for more than 100 years. The toxicology of many forms of uranium, ranging from dust of several oxides to soluble uranyl ion, was thoroughly studied during the Manhattan Project in the United States in the 1940s. The development of depleted uranium kinetic penetrators as armor-piercing incendiary weaponry produced a novel form of uranium environmental contamination, which led to greater susceptibility to the adverse health effects of the toxic heavy metal after its use in various military conflicts. The aerosol from burning uranium penetrator fragments is rapidly dissolved in biological fluids and readily absorbed from the lungs, leading to a wide range of toxic effects. We have studied some chelating agents for uranyl ion, including citrate ion and desferal (desferrioxamine B), which may be effective for minimizing the toxic effects of this insidious heavy metal. Some characteristics of the desferrioxamine complex are presented, along with information about the use of citrate as an effective chelating agent for therapy of uranium toxicity.

AbstractObjective:The aim of this study was to evaluate the effects of low level laser therapy (LLLT) on the degenerative process in the articular cartilage after an anterior cruciate ligament transection (ACLT) model in rats.Methods:Eighty male rats (Wistar) were divided into four groups: 1.) intact control group (CG), 2.) injured control group (ICG), 3.) injured laser-treated group at 10 J/cmResults:Initial signs of tissue degradation could be observed 5 weeks post-ACLT, evidenced by the decrease of proteoglycan concentration and increase in cartilage thickness of the ICG. After 8 weeks post-surgery, analysis showed a progression of the degenerative processes in the ICG revealed by the increased cellularity and higher TNF-α, IL1-β and MMP-13 immunoexpression. LLLT was able to modulate some of the aspects relating to the degradative process, such as biomodulation of the number of chondrocyte proliferation, prevention of proteoglycan loss, and decrease of MMP-13 immunoexpression.Conclusion:This study showed that the 685-nm laser irradiation, especially at 10 J/cm
Percutaneous selective laser amygdalo-hippocampectomy (SLAH) for treatment of mesial temporal lobe epilepsy within an interventional MRI suite
Authors: Nour Sherif G. , Willie Jon T. , Gross Robert E. 
Published: May 2014

AbstractPercutaneous selective laser amygdalo-hippocampectomy (SLAH) procedure is a new minimally invasive alternative to surgical amygdalo-hippocampectomy that involves targeted, controlled laser energy deposition under real-time magnetic resonance imaging (MRI) monitoring within a dedicated “interventional MRI” suite. Technical feasibility, safety and initial efficacy results from our program are encouraging and indicate a potential for paradigm shift in future treatment of patients with exclusively or predominantly focal unilateral seizure onsets within the mesial temporal lobe. Several institutions are currently employing this technology and more long-term follow-up results on larger cohorts of patients are expected in the near future. This article reviews the principles of MRI-guided SLAH, procedure set-up and equipment, the detailed phases of intra-procedural MRI guidance and treatment monitoring, and the MRI appearance of the resultant thermal ablation zones. We conclude with a discussion of our institutional experience at Emory University with MRI-guided SLAH as one of the leading sites offering this state-of-the-art technology.

Abstract
Tritium labeling was introduced into detonation nanodiamonds (ND) through the tritium thermal activation method. Two target
preparation techniques were developed to increase the radioactivity and the specific radioactivity of the labeled product: the
desiccation of the waterless solvent suspension and the lyophilization of the hydrosol. The specific radioactivity of the
labeled product was shown to correlate with the hydrogen content in the starting material and to achieve 2.6 TBq/g.

Published: May 2014

Abstract
Adsorption of Sr on multi-walled carbon nanotubes (MWCNTs) was investigated to explore their possible use as an efficient adsorbent for
nuclear waste streams. MWCNTs were purified and oxidized with HNO3 prior to testing adsorption. Oxidized MWCNTs were then employed
in batch experiments as sorbent of Sr from aqueous solutions. The Box–Behnken experimental design was used to suitably vary the
parameters of interest, i.e., temperature, initial Sr2+ concentration, and shaking time. Langmuir, Freundlich and
Dubinin–Radushkevich models were applied to fit the adsorption isotherms. The Dubinin–Radushkevich model exhibited the best
agreement. Adsorption kinetics was also studied; it was well described by a pseudo-second-order rate model. Adsorption thermodynamics
was investigated in the temperature range 293–333 K; the variations of the standard free energy (ΔG
○),
standard enthalpy (ΔH
○) and standard entropy (ΔS
○) were obtained. Oxidized MWCNTs show the
potential to be a promising candidate for the pre-concentration and solidification of Sr from large volumes of aqueous solution.

Published: May 2014

Abstract
In this study, a simple and rapid dispersive liquid–liquid
microextraction (DLLME) was developed for the determination of
uranium in water samples prior to high performance liquid
chromatography with diode array
detection. 1-(2-pyridylazo)-2-naphthol (PAN) was used as
complexing agent. The effect of various parameters on the
extraction step including type and volume of extraction and
dispersive solvents, pH of solution, concentration of PAN,
extraction time, sample volume and ionic strength were studied and
optimized. Under the optimum conditions, the limit of detection
(LOD) and preconcentration factor were
0.3 μg L−1 and 194,
respectively. Furthermore, the relative standard deviation of the
ten replicate was <2.6%. The developed procedure was then
applied to the extraction and determination of uranium in the
water samples.
An overview on the role of wheat gluten as a viable substitute for biodegradable plastics
Authors: Patni Neha , Yadava Pujita , Agarwal Anisha , Maroo Vyoma 
Published: May 2014

Abstract
Petroleum resources are limited and stringent environmental concerns are increasing; biodegradable materials made from renewable agricultural resources such as carbohydrates, starch and proteins are attracting much attention for sustainable development and environmental conservation. As per the annual production of wheat in India, it is the second largest producer in the world after China. In this paper, we explore the possibility of wheat protein known as gluten as a promising substitute for petroleum-based plastics and environment-friendly thermosetting composites. Plant proteins from wheat show an advantage for use as films and plastics because of their abundant resources, low cost, good biodegradability and suitable properties like rheological properties, water sensitivity, sound absorption and thermal behavior. The paper aims to explain the extraction of gluten and to review the blending of gluten with different plasticizers such as glycerol, water and some cross-linking agents to enhance the above-mentioned properties. An extensive review of the existing literature reveals that wheat gluten (WG)-based bioplastics are nontoxic and fully biodegradable, whatever the technological process is applied; thus, the paper also discusses the biodegradability of WG-based bioplastics. We conclude the paper by incorporating a critical summary of the various parameters and chemicals used to enhance the properties of gluten-based composites.

Published: May 2014

Abstract
Increase in energy demand and consumption has been accompanied by a corresponding increase in sulfur emissions. These pollutants have both health and economic consequences. Furthermore, it significantly reduces the efficiency of advanced emission control systems of diesel engines, thereby indirectly causing more harm to the environment. This resulted in stringent sulfur emission limit down to about 15 ppm or less and in turn served as an incentive for research into alternative sulfur reduction technologies. Although feasible improvements to hydrodesulfurization are currently under investigation, adsorptive, extractive, oxidative and biodesulfurization have also been studied in recent years. Oxidative desulfurization appears to be one of the most promising desulfurization technologies due to its broadness and compatibility with other technologies such as extractive, adsorptive and biodesulfurization. The advent of ionic liquids as extraction solvents has made this even more so. This work, therefore, reviews the different approaches and investigations carried out on oxidative desulfurization while identifying research gaps and giving important recommendations.

AbstractOur earlier report has shown that salt substitutes (Obu-Otoyo) contain some toxic heavy metals. This study, therefore, investigated the effect of the dietary inclusion of salt substitutes (Obu-Otoyo), namely, salt “A” and “B”, on biomarkers of oxidative stress and renal function in rats. Salt “A”, which has a gray color, is the product of a process in which ash is produced by burning palm kernel shaft soaked in water overnight and extracting the residue to produce the salt substitute while Salt “B”, which has a white color, is a rock salt mined from a local site at Ilobu town, Osun-State, Nigeria. Salt substitutes were fed to normal rats as dietary inclusion at 0.5% and 1.0% for 21 days. The dietary inclusion of the salt substitutes caused a significant (p<0.05) increase in plasma activities of creatinine, urea, uric acid, and blood urea nitrogen compared with the control. Meanwhile, the dietary inclusion of the salt substitutes caused a significant (p<0.05) decrease in renal superoxide dismutase, catalase, reduced glutathione level, glutathione-S-transferase, and glutathione peroxidase activities with a concomitant increase in the malondialdehyde level compared with the control. Furthermore, there was a significant (p<0.05) increase in the concentrations of heavy metals, such as Pb, Co, Cu, Fe, Zn and Cr, in kidney of rats fed with the salt substitute Obu-Otoyo. Therefore, this finding indicates that Obu-Otoyo induces nephrotoxicity in rats. The nephrotoxicity of Obu-Otoyo could be attributed to the induction of oxidative stress as a result of the presence of some heavy metals, suggesting possible health hazards in subjects who consume it.
How do Attributes of Broadband Plans Affect Price?
Authors: Wallsten Scott J. , Riso James 
Published: May 2014

AbstractBroadband has become ubiquitous across OECD countries, yet because it is typically sold as part of a bundle of services, each with its own set of options, little research has explored how it is priced. In this paper we assemble a new dataset of more than 25,000 residential and business broadband plans from all OECD countries from 2007 to 2009 to explore how data metering, service contracts, and bundling voice, video, and data affect the prices consumers pay. We find that faster speeds are correlated with higher prices, although prices increase at a decreasing rate as speeds increase. Additionally, bundles including voice and video are more expensive than standalone service, and plans with more channels included in video bundles are more expensive than plans with fewer channels. Finally, the analysis shows tradeoffs consumers and suppliers make: plans with data caps are less expensive than those without caps and plans with contracts are less expensive than month-to-month plans.
