BIODEGRADATION OF SOME PAHs BY A LOCALLY-ISOLATED STRAIN OF ACTINOMYCETES

Samples from the River Nile, the Mediterranean, and the Red Sea were chemically and microbiologically evaluated. The chemical analysis proved that cations and anions concentrations were of higher values in seawater samples in comparison with those of the Nile water. The microbiological analysis showed that Cairo University Nile Bus Station samples (GCB-19) recorded the increased total viable microbial counts (1.6x104 CFU/ml). Total coliforms highest counts were analyzed in GCB-19 samples (110 cells/ml), whereas fecal coliforms highest counts (15 cells/ml) were recorded in Cairo University Nile Bus Station samples (GCB-17) and (GCB-19). PAHs were determined in the collected samples using GC/MS. Seawater samples had increased concentrations of PAHs in comparison with River Nile water ones. Fluorene was the major PAH in all water samples, for it ranged from 25 to 50 ppt. An actinomycetes isolate from the collected samples underwent molecular identification through the pair-wise alignment of its 16S rDNA sequence with sequences in the database. It was indicated that it was identical to Streptomyces macrosporeus with a 98.65% homology sequence. Streptomyces macrosporeus was examined for degradation efficiency of 0.1, 0.05, 0.025, and 0.0125 ppm of PAHs standard mix and 200 ppm of naphthalene, fluorene, and anthracene, individually for 5 days/37 C. It degraded all the detectable concentrations of the chemicals in the PAHs standard mix except for some non-degradable traces of naphthalene. Furthermore, it degraded naphthalene, fluorene and anthracene individually with a percentage of 99.99%, 94.88%, and 96.33%, respectively. Thus, the results of the current study reflected the biodegradation capability of Streptomyces macrosporeus for different PAHs.
Building Retrofit and Energy Conservation/Efficiency Review: A Techno-Environ-Economic Assessment of Heat Pump System Retrofit in Housing Stock

The world has not been able to achieve minimum greenhouse gas emissions in buildings’ energy consumptions because the energy and emissions optimization techniques have not been fully utilized. Thermal comfort is one of the most important issues for both residential and commercial buildings. Out of the 40% of global energy consumed by buildings, a large fraction is used to maintain their thermal comfort. In this study, a comprehensive review of the recent advancements in building energy conservation and efficiency application is presented based on existing high-quality research papers. Additionally, the retrofit of the heating/cooling and hot water system for an entire community in Cyprus is presented. This study aims to analyze the technical and environmental benefits of replacing existing electric heaters for hot water with heat pump water heating systems and the use of heat pump air conditioners for thermal comfort in place of the existing ordinary air conditioners for space heating and cooling. One administrative building, 86 apartments (including residential and commercial) buildings, and a restaurant building is retrofitted, and the feasibility of the project is determined based on three economic indicators, namely; simple payback period (SPP), internal rate of return (IRR), and net present value (NPV). The electrical energy required by the hot water systems and the heating/cooling system is reduced by 263,564 kWh/yr and 144,825 kWh/yr, respectively. Additionally, the retrofit project will reduce Cyprus’ CO2 emission by 121,592.8 kg yearly. The SPP, IRR, and NPV for the project show that the retrofit is economically feasible.

Who Moves My App Promotion Investment? A Systematic Study About App Distribution Fraud

As the mobile era matures, it is increasingly competitive to market mobile apps, forcing companies to invest heavily on mobile user acquisition campaigns. This has unfortunately given birth to a new form of Internet fraud, which we refer to as “app distribution fraud”. This new fraud involves collusion between ISPs and fraudulent app distributors where app download is hijacked/redirected. In this article, we have the unique opportunity to cooperate with a major e-commerce company (with about 0.2 billion active users per month) to take a first peek at this problem. Through the nationwide measurement results, we find that app distribution fraud is ubiquitous yet stealthy — about 1.55 percent app downloads are hijacked/redirected, affecting more than 75 percent of the cities we tested and causing an estimated 7.46 billion U.S. dollars financial loss per year. We follow up with additional measurements on the technical mechanism of the fraud and the scope of the fraud (i.e., what other apps are also affected). Surprisingly, we find that sometimes the original app a user intends to download can be replaced with a completely different app, rendering the user's device at risks.
Measurement of Black Hole Spin via X-ray Reflection Spectra

The measurement of black hole spin is of great significance. The methods of measuring the spin have been discussed for a long time. For this important astrophysical problem, the paper begins with the significance of measuring a black hole spin and focuses on the theory of measuring the spin via the X-ray reflection recognized as iron line spectrum method. The paper also discusses the popular reflection models and explains the important parameters. Besides, the other methods of spin measurement are introduced, mainly comparing them with the X-ray reflection method. Finally, the advantages and disadvantages of the X-ray reflection method are summarized.
Two negative minima of the first normal stress difference in a cellulose‐based cholesteric liquid crystal: Helix uncoiling

The shear rate dependence of material functions such as shear viscosity (η) and the first normal stress difference (N1) were given and interpreted earlier by Kiss and Porter. Their widely accepted work revealed the possibility of having a negative minimum of N1 for polymeric liquid crystals. In this work, we disclose for the first time the evidence of two negative N1 minima on a sheared cellulosic lyotropic system. The lower shear rate minimum is ascribed to the uncoiling of the cholesteric helix, as theoretically predicted earlier. Our findings contribute also to the understanding of the other minimum already reported in the literature and attributed to the nematic director tumbling mode. Moreover, the elastic change that the LC-HPC sample undergoes during the helix unwinding of the cholesteric structure is also by means of oscillatory measurements. This study is a contribution for the understanding of the structure-properties relationship linked with the complex rheological behavior of chiral nematic cellulose-based systems and may help to improve their further processing. © 2017 Wiley Periodicals, Inc.

Novel rectangular‐to‐circular waveguide mode converter based on using one‐step double‐cruciform waveguide for millimetre‐wave applications

A novel design for a TE 10 ‐ mode rectangular waveguide to a TE 11 ‐ mode circular waveguide mode converter based on the use of an intermediate one ‐ step double ‐ cruciform section is proposed. The converter achieves compactness and broadband by employing the one ‐ step double ‐ cruciform transition instead of the conventional multi ‐ step transi-tions or smooth transitions. Due to the one ‐ step structure, the converter achieves an extremely short ‐ length (around 0.3 λ , where λ is the wavelength at the centre frequency), which makes it suitable for highly compact systems. For verification purpose, a back ‐ to ‐ back connection rectangular ‐ to ‐ circular mode converter was fabricated and measured. The measured results show that the return loss is around 15 dB and the insertion loss is around 0.4 dB in the operating frequency band. Thus, we can infer that the return loss and insertion loss of a single mode converter are around 19 and 0.2 dB, respectively. The experimental results reasonably agree with the simulated results.
Immersion and Invariance Adaptive Pose Control for Spacecraft Proximity Operations Under Kinematic and Dynamic Constraints

This article studies the six-degree-of-freedom pose control issue of spacecraft proximity operations subject to kinematic and dynamic constraints, as well as parameter uncertainties. A transformed relative translational dynamics and a line-of-sight frame are introduced to facilitate the pose control design. In this context, an immersion and invariance (I&I) adaptive pose control scheme based on artificial potential functions (APFs) is proposed. Specifically, a class of APFs that are free of local minima are first constructed to deal with kinematic and dynamic constraints imposed by certain safety and physical requirements. Second, using the dynamic scaling technique, an I&I adaptive pose controller is tactfully designed. This controller is shown to be able to circumvent the realizability condition that is required for most of the existing adaptive control approaches, but nonetheless may not hold under dynamic constraints. Third, through Lyapunov's direct method, the asymptotic stability of the closed-loop system is analyzed. The proposed method enables the pursuer to arrive at the desired anchoring point with a specified pointing, while satisfying both kinematic and dynamic constraints. Moreover, it depends upon the I&I adaptive design philosophy and, therefore, introduces an attracting manifold, whereby the deterministic case of closed-loop performance (no effect of parameter uncertainties) can be asymptotically recovered. Simulation results illustrate the efficiency of the proposed control scheme.
Diffusion of Hydrogen and Deuterium in High Purity Iron between 222 and 322 K

method of electrochemical hydrogen permeation. In this method, the diffusion coefficient is evaluated from the frequency response of the phase difference between an anodic permeation current and a cathodic charging current and it is possible to separate the surface effect from the permeation process. In the present study, the diffusion coefficients of hydrogen (DH) and deuterium (DD) in high purity iron were measured by this method at temperatures between 222 and 322K, using alcoholic solutions as electrolytes. In order to study the effect of dislocations on hydrogen diffusion, the diffusion coefficients in coldrolled high purity iron were also measured. The mass effect and the trapping effect on hydrogen diffusion are discussed.
Effect of Nitrate Donor on Nitrate Conversio in Escherichia coli.

Nitrate compound are prodrugs and required degradation to nitrite and furthermore bioactivated to nitric oxide (NO), an active beneficial form for physiological purpose e.g. on angina pectoris. Through the use of nitrate donor per oral, it was alleged that Escherichia coli, normal bacterial in the gut, decompose and reduce nitrate concentration and shows itself as chemoorganoheterotrophs organism. This research aim to investigate the role of nitrate donor compounds i.e.isosorbide dinitrate (ISDN) and natrium nitrate (NaNO3) on E.coli, in terms of concentration of nitrite as catabolism product and bacteria numbers. Six groups of nitrate donors varies in concentration (100, 500 and 1000 ppm) is dissolved in 3000 ppm glucose solution. After incubated for 24 hours Griess method is applied for measurement of nitrite concentration. Using spectrofotometric bacterial counting method, then bacteria number is obtained. The results showed that increasing nitrate concentration does not influence the growth or bacteria numbe of E. coli, but correlate with amount of nitrite formed.

Growth and carrier-transport performance of a poly(3-hexylthiophene)/1,2,3,4-bis(p-methylbenzylidene) sorbitol hybrid shish-kebab nanostructure

Poly(3-hexylthiophene) (P3HT)/1,2,3,4-bis(p-methylbenzylidene) sorbitol (MDBS) hybrid shish-kebab nanostructures were prepared by spin-coating their hot o-dichlorobenzene (ODCB) solutions. The P3HT nanofibrils grow perpendicularly to the MDBS nanowire surface with uniform width and height. The lengths of these P3HT nanofibrils are controlled by solvent evaporation rate and P3HT solubility in ODCB at different temperatures during spin-coating. The P3HT nanofibril length also can be tailored through variations in spin-coating temperatures, spin-coating rates, P3HT concentrations, and solvent quality or substrates. The method is shown to be general to several other poly(3-alkylthiophene)s (P3ATs) and sorbitol derivatives. The mobility of the P3HT/MDBS thin-film organic field-effect transistor (OFET) with the hybrid shish-kebab morphology is 3.80 × 10−2 cm2 V−1 s−1, which is one order of magnitude higher than the mobility (2.91 × 10−3 cm2 V−1 s−1) of the OFET using only P3HT. In this work, we provide a simple and robust route to form hybrid shish-kebab nanostructures of organic conjugated polymers. Our findings suggest that this nanostructure has the benefit of improving the carrier transport of organic semiconductor materials.
Drought and soil nutrients effects on symbiotic nitrogen fixation in seedlings from eight Neotropical legume species

Symbiotic nitrogen fixation is a dominant source of nitrogen to many terrestrial ecosystems and thus may influence their responses to global change. High legume species diversity and abundance are thought to lead to high rates of symbiotic nitrogen fixation in Neotropical forests. However, how changes in water and nutrient availability will affect symbiotic nitrogen fixation has only recently been explored, even as droughts begin to increase in severity and frequency in the Neotropics. To explore these effects, we grew eight species of Neotropical woody legume seedlings in a shadehouse for four months while manipulating soil water, phosphorus, and molybdenum availability. Overall, drought reduced nodule biomass, nitrogenase activity (acetylene reduction g‐1 nodule), and acetylene reduction per seedling by 33%, 27%, and 41%, respectively, but reduced seedling biomass by only 18%. Species varied in the manifestation of drought effects. For example, drought reduced the probability that nodules formed in some species, but in others reduced the nitrogenase activity or acetylene reduction per seedling. In contrast, the effects of phosphorus and molybdenum availability were more species‐specific. However, fertilization did affect (both positively and negatively) one or more symbiotic nitrogen fixation response variables in two of the eight species. Our results indicate drought reduces symbiotic nitrogen fixation in Neotropical legume seedlings, but the mechanism of response may be species‐specific. Therefore, predicting the response of symbiotic nitrogen fixation in the Neotropics to a changing climate, with expected increases in drought frequency and severity, may require grappling with the diversity of responses among nitrogen‐fixing legumes.
A Spectral Grouping and Attention-Driven Residual Dense Network for Hyperspectral Image Super-Resolution

Although unprecedented success has been achieved in convolutional neural network (CNN)-based super-resolution (SR) for natural images, hyperspectral image (HSI) SR without auxiliary high-resolution images remains a challenging task due to the high spectral dimensionality, where learning effective spatial and spectral representations is of great importance. In this article, we introduce a novel CNN-based HSI SR method, termed spectral grouping and attention-driven residual dense network (SGARDN) to facilitate the modeling of all spectral bands and focus on the exploration of spatial-spectral features. Considering the block characteristic of HSI, we employ group convolutions in and between groups composed of highly similar spectral bands at early stages to extract informative spatial features and avoid spectral disorder caused by normal convolution. To exploit spectral prior, a new spectral attention mechanism constructed by covariance statistics of features is designed to adaptively recalibrate features. We adapt the spectral attention for group convolutions to rescale grouping features with holistic spectral information. These two sequential operations called spectral grouping and integration module aim to extract effective shallow spatial-spectral features that are reused in the following layers. On the other hand, the residual dense block can better deal with spatial–spectral features by experimental comparison and hence is combined with the spectral attention to form a new basic building block for powerful feature expression and spectral correlation learning. The experimental results on synthesized and real-scenario HSIs demonstrate the feasibility and superiority of the proposed method over other state-of-the-art methods.
Formulation and characterization of carvedilol buccal mucoadhesive patches

Bioadhesive formulations have a wide scope of application for both systemic and local effects of the drug. The oral transmucosal drug delivery bypasses liver and avoids pre-systemic elimination. Carvedilol (Dose-3.125-25 mg) is βadrenergic antagonist. Its oral bioavailability is 25-35% because of first pass metabolism. FTIR method revealed no interaction between carvedilol and polymers. Carvedilol patches were prepared using HPMC K15 and Carbopol 940.The patches were evaluated for their thickness, folding endurance, weight and content uniformity, swelling behaviour, mucoadhesive strength and surface pH. In vitro release studies were conducted for carvedilol-loaded patches in phosphate buffer (pH, 6.8) solution. The patches exhibited drug release in the range of 77.05 to 97.20% in 8 hours. Data of in vitro release from patches were fitted into kinetic models (Higuchi and Korsmeyer-Peppas models) to explain release profiles. The optimized formulation (patch V) showed first order release followed by zero order.
The feasibility and acceptability study of a positive psychology group intervention for people with severe psychiatric conditions

ABSTRACT The process of recovery from mental health can be improved by promoting wellness. Third-generation perspectives promote non-judgmental acceptance of problems as well as the development of a person’s well-being and strengths. The aim of this study is to test the feasibility, acceptability and effectiveness of a group intervention to improve well-being in people with severe psychiatric conditions. Results showed that the protocol was feasible and highly acceptable, showing high attendance and adherence rates as well as high satisfaction. On completion of group therapy, participants reported a significant improvement in self-acceptance and significant decreases in interpersonal sensitivity and depression. The results indicate that positive psychology group therapy may be a powerful complementary strategy among people with severe psychiatric conditions. Though the validity of the study is limited by the lack of comparison group, the present study will allow for the optimisation of trial processes and a future definitive randomised control trial.
