Stellar flare diagnostics from multi–wavelength observations

Abstract Quasi–periodic pulsations in various wavebands are natural manifestations of emission of stellar flares. We suggest a diagnostic tool of stellar flares based on the coronal seismology and the solar–stellar analogy. Two approaches are used: (I) flare loop as a resonator for MHD oscillations and (II) flare loop as an equivalent electric circuit. Using optical, X–ray, and radio data we obtained flare plasma parameters for the red dwarfs EQ Peg, AT Mic, and AD Leo. The characteristic length of stellar flare loops l ~ R* and their electric currents turned out to be one–two orders of magnitude lager than the solar ones. Advantages of proposed diagnostics in comparison to the scaling law methods are given.
I-Effect of some Chemical Treatments on Keeping Quality and Vase Life of Cut Chrysanthemum Flowers a-Effect of some metal salts solution on postharvest quality of cut chrysanthemum

Quality of cut flowers is an important issue at postharvest as well as an important factor contributing to marketing of and profitability from the chrysanthemum. A trial was consummated at Postharvest Lab of Floriculture Res. Dept. Hort. Res. Inst. ARC, Giza, Egypt during 2014 and 2015 seasons to study the effect of some metal salts at different concentrations on three cultivars of chrysanthemum. The obtained results indicated that all measured characters, i.e. longevity, water uptake, water loss, dry matter, diameter of head and relative fresh weight improved significantly by applying copper sulfate at 50, 150 and 250 mg/l, cobalt chloride at 150, 300 and 450 mg/l and aluminum sulfate at 100, 250 and 400 mg/l, in addition to sucrose at 20 g/l and citric acid at 0.2 g/l. All these treatments were compared to distilled water as a control. The effects varied between the Arctic Queen, Marabou and Pink Loly Pop cultivars, due to genetic variations in response to these chemical compounds. Pink Loly Pop was the most responsive to the different transactions, as it gave the maximum lifespan period compared to the other two cultivars. The best treatment was copper sulfate at 150 mg/l + sucrose at 20g/l + citric acid at 0.2 g/l, as it enhanced the longevity of cut flowers, reduced water loss and induced the highest rate of relative fresh weight in both seasons. On the other hand, application of aluminum sulfate at the different concentrations increased diameter of flowers and raised their dry matter during the two seasons. Almost all preservative solutions significantly increased chlorophyll a, b and carotenoids content over the control. Total and reducing sugar; and total anthocyanins were affected by aluminum sulfate impact on different cultivars in this experiment.
A Decline in the X-Ray through Radio Emission from GW170817 Continues to Support an Off-axis Structured Jet

We present new observations of the binary neutron star merger GW170817 at Δt ≈ 220–290 days post-merger, at radio (Karl G. Jansky Very Large Array; VLA), X-ray (Chandra X-ray Observatory), and optical (Hubble Space Telescope; HST) wavelengths. These observations provide the first evidence for a turnover in the X-ray light curve, mirroring a decline in the radio emission at ≳5σ significance. The radio-to-X-ray spectral energy distribution exhibits no evolution into the declining phase. Our full multi-wavelength data set is consistent with the predicted behavior of our previously published models of a successful structured jet expanding into a low-density circumbinary medium, but pure cocoon models with a choked jet cannot be ruled out. If future observations continue to track our predictions, we expect that the radio and X-ray emission will remain detectable until ∼1000 days post-merger.
COMPARISON TO VISUAL EXAMINATION IN DETECTION OF OCCLUSAL CARIES IN PERMANENT MOLARS AND PREMOLARS

The objective of this study was to evaluate and compare laser fluorescence (LF), using DIAGNOdent tool and visual examination (VE) methods for diagnosis of early occlusal caries in permanent molars and premolars. Two hundred occlusal surfaces were randomly selected in permanent molars and premolars of 54 female patients (17-25 years old), visited Dental Hygiene Clinics of College of Dentistry, King Saud University, Riyadh, Saudi Arabia. Clinical examination for dental caries using LF and VE methods was conducted by two examiners. The agreement between the two examiners was almost perfect (Kappa .87 and 1.0) using LF and VE for diagnosis of the occlusal caries. There was no significant difference in sensitivity and specificity value of the two methods. It is also concluded that the laser fluorescence can be used as an adjunct tool in the diagnosis of occlusal dental caries in permanent molars and premolars.
Effect of Acetic Acid on Co 2 O 3 Catalyzed Autoxidation of Aqueous Sulphur Dioxide in Alkaline Medium

Original Research Article The kinetics of the acetic acid inhibited Co2O3 catalysed autoxidation of S (IV) in alkaline medium has been studied and based on the observed results following rate has been proposed. Rate constants and the order of reaction were calculated and the reaction was found to be pseudofirst order in all cases. The effect of pH and temperature are also discussed. The value of apparent activation (Ea) energy was by Arrhenius equation. On the basis of inhibition parameters the reaction follows free radical mechanism.
Changes in Essential Oil Content and Composition of Clary Sage (Salvia sclarea) Aerial Parts during Different Phenological Stages

The variations in quantity and quality of essential oils (EOs) of Salvia sclarea L. (Lamiaceae) were examined at different phenological stages (i.e. rosette, stem initiation, full flowering, and fruit set) of the life cycle of species. The EOs of air-dried samples were obtained by hydrodistillation. The yields of EOs (w/w %) were 0.23, 0.15, 1.36, and 1.35% at rosette, stem initiation, full flowering, and fruit set stages, respectively. The EOs were analyzed by GC and GC-MS. A total of 17, 27, 19, and 51 components were identified and quantified at the above mentioned stages, respectively. The proportions of linalool and linalyl acetate, as major oil constituents were highest at the full flowering stage. However, the main group of compounds at the rosette stage was the monoterpene esters (53.36%) and at stem initiation the sesquiterpenes (57.7%). Moreover, monoterpene alcohols were the predominant compounds at full flowering (43.7%) and at fruit set (34.88%) stages. _____________________________________________________________________________________________________________

Transactions on Human-Computer Interaction Volume 10 Issue 2 6-2018 Successful System Use : It ’ s Not Just Who You Are , But What

Information and communication technologies are so embedded in contemporary society that we have arrived at the point at which learning to use technology successfully may affect our day-to-day lives as much as learning to eat or exercising properly. However, we lack research that explains and predicts successful system use (i.e., system use that adds value to the user). We theorize that adaptive behaviors (e.g., trying new features, repurposing features) mediate the relationship between user characteristics and successful system use. To better understand successful system use, we used an online survey to study how undergraduate students enrolled in an information systems course used an information system (Microsoft Excel). Our findings suggest that adaptive behaviors do act as a mediator between user characteristics and successful system use; therefore, it is not only one’s identity but also what one does that drives successful system use. One of our key contributions includes remodeling system success as a single second-order construct as opposed to its traditional form as a series of causally related constructs.
Response of hybrid rice to different levels of nitrogen and phosphorus

The Experiment was carried out at Sher-e-Bangla Agricultural University, Dhaka during November, 2010 to May 2011 to study the response of hybrid rice to different levels of nitrogen and phosphorus. The experiment was laid out on split plot design with three replications having nitrogen levels in the main plot and phosphorus in the sub plot. There were six nitrogen fertilizer levels viz., 0, 80, 120, 160, 200 kg N ha -1 , urea super granules @ 75 kg N ha -1 and four phosphorus fertilizer levels viz., 0, 30, 50 and 70 kg P2O5 ha -1 . Urea was top dressed in three equal splits at 10, 35 and 55 days after transplanting (DAT). One urea super granules (USG) was placed at 10 cm soil depth at 10 DAT in the centre of four hills in alternate rows @ 75 kg N ha -1 . Results indicated that the effect of nitrogen and phosphorus showed significant variation in respect of yield contributing characters and yield. At harvest, maximum effective tillers hill -1 (13.63), filled grains panicle -1 (154.67), 1000 grain weight (29.35 g), grain yield ( 9.42 t ha -1 ), straw yield (13.33 t ha -1 ) was obtained from the application of urea super granules. About 10% more grain yield was measured from urea super granules than prilled urea. Phosphorus at 50 kg P2O5 gave the highest grain yield (7.85 t ha -1 ). Interaction effect showed that application of urea super granules along with 50 kg P2O5 ha -1 gave the highest (9.83 t ha -1 ) grain yield. On the other hand application of 160 kg N ha -1 and 120 kg N ha -1 prilled urea along with 50 kg P2O5 ha -1 gave grain yield as 8.83 t ha -1 and 7.67 t ha -1 , respectively.
{ Corner Pixel Tracking Mapping Geometric Photometric Photometric ResidualsFeatures

Monocular Odometry systems can be broadly categorized as being either Direct, Indirect, or a hybrid of both. While Indirect systems process an alternative image representation to compute geometric residuals, Direct methods process the image pixels directly to generate photometric residuals. Both paradigms have distinct but often complementary properties. This paper presents a Unified Formulation for Visual Odometry, referred to as UFVO, with the following key contributions: (1) a tight coupling of photometric (Direct) and geometric (Indirect) measurements using a joint multi-objective optimization, (2) the use of a utility function as a decision maker that incorporates prior knowledge on both paradigms, (3) descriptor sharing, where a feature can have more than one type of descriptor and its different descriptors are used for tracking and mapping, (4) the depth estimation of both corner features and pixel features within the same map using an inverse depth parametrization, and (5) a corner and pixel selection strategy that extracts both types of information, while promoting a uniform distribution over the image domain. Experiments show that our proposed system can handle large inter-frame motions, inherits the sub-pixel accuracy of direct methods, can run efficiently in real-time, can generate an Indirect map representation at a marginal computational cost when compared to traditional Indirect systems, all while outperforming state of the art in Direct, Indirect and hybrid systems.
Plasma-Derived Graphene-Based Materials for Water Purification and Energy Storage

Several crucial problems, such as rapid population growth and extended demands for food, water and fuels, could lead to a severe lack of clean water and an energy crisis in the coming decade. Therefore, low-cost and highly-efficient technologies related to filtration of alternative water supplies (e.g., purification of wastewater and water-rich liquids) and advanced energy storage (e.g., supercapacitors) could play a crucial role to overcome such challenges. A promising class of solid materials for these purposes is exfoliated graphene, and more specifically, its nanoporous forms that exhibit large specific surface areas and pore volumes. In the current work, two plasma-exfoliated graphene-based materials with distinctive morphological and porosity features, including non-porous and low-specific surface area platelets versus nanoporous and high-specific surface area flakes, were tested as filters for water purification purposes (i.e., decolourization and deacidification) and as electrodes for supercapacitors (i.e., ion electrosorption). The findings of this study suggest that a nanoporous and large specific surface area graphene-based material promotes the water purification behaviour by removing contaminants from water-based solutions as well as the energy storage performance by confining ions of aqueous electrolytes.
Dexmedetomidine in the Management of Awake Fiberoptic Intubation

Awake Fibreoptic Intubation (AFOI) is, nowadays, the gold standard in predicted difficult airway management. Numerous practice guidelines have been developed to assist clinicians facing with a difficult airway. If conducted without sedation, it is common that this procedure may lead to high patient discomfort and severe hemodynamic responses. Sedation is frequently used to make the process more tolerable to patients even if it is not always easy to strike a balance between patient comfort, safety, co-operation, and good intubating conditions. In the last years, many drugs and drug combinations have been described. This minireview aims to discuss the evidence supporting the use of Dexmedetomidine (DEX) in the AFOI management.
Development and Optimization of an Integrated Process Conﬁguration for IGCC Power Generation Technology with a Fischer-Tropsch Fuels from Coal and Biomass

The conversion of coal into high-quality fuels is carried out through gasification, syngas production and the process of Fischer-Tropsch. Additionally, produced syngas derived from coal gasification only can generate power and heat in a combined cycle power plant. In order to combine these two methods together in an integrated process at the same time, it is necessary to use part of the produced gas for the production of heat and power, and the other part for the production of liquid fuel. As a result, this new and integrated process will consist of three major parts: "coal gasification", "power and heat generation" and "production of liquid fuel". The purpose of this study is by consideration of an integrated gasification combined cycle (IGCC) plant with input feed of coal, an integrated system of "Combined heat and power as well as liquid fuel of Fischer-Tropsch", called in this research CHPF is designed, and the optimum amounts of production of the power, heat and liquid fuel are provided at a certain scale of the feedstock. Thus, the various parts of this integrated process is designed conceptually, and simulated and integrated with Aspen software; then an objective function is defined to maximize the revenue from the sale of process products (power and liquid fuels). To ensure the accuracy of the results, the sensitivity analysis tool is used; and the simulation and design results are compared with an experimental work, indicating that the difference in results is about 4%.
Material characterization Scanning electron microscopy ( SEM ) and energy dispersive X-ray analysis ( EDAX )

Correspondence: Thomas J Webster Department of Chemical Engineering, Northeastern University, Boston, MA, USA Tel +1 617 373 8565 Email th.webster@neu.edu Abstract: In hospitals and clinics worldwide, medical device surfaces have become a rapidly growing source of nosocomial infections. In particular, patients requiring mechanical ventilation (and, thus, intubation with an endotracheal tube) for extended lengths of time are faced with a high probability of contracting ventilator-associated pneumonia. Once inserted into the body, the endotracheal tube provides a surface to which bacteria can adhere and form a biofilm (a robust, sticky matrix that provides protection against the host immune system and antibiotic treatment). Adding to the severity of this problem is the spread of bacterial genetic tolerance to antibiotics, in part demonstrated by the recent and significant increase in the prevalence of methicillin-resistant Staphylococcus aureus. To combat these trends, different techniques in biomaterial design must be explored. Recent research has shown that nanomaterials (materials with at least one dimension less than 100 nm) may have the potential to prevent or disrupt bacterial processes that lead to infections. In this study, polyvinyl chloride (PVC) taken from a conventional endotracheal tube was embedded with varying concentrations of zinc oxide (ZnO) nanoparticles. S. aureus biofilms were then grown on these nanocomposite surfaces during a 24-hour culture. Following this, biofilms were removed from the surfaces and the number of colony forming units present was assessed. Bacterial proliferation on the samples embedded with the highest concentration of ZnO nanoparticles was 87% less when compared to the control, indicating that this technique is effective at reducing biofilm formation on PVC surfaces without the use of antibiotics.
Clinical Outcome of Patients With Schizophrenia Without Maintenance Treatment in a Nonindustrialized Society by Toshiyuki Kurihara

The outcome of 51 patients with schizophrenia (DSM-III-R) consecutively admitted to Bangli State Mental Hospital (Bah*) with no prior psychiatric treatment was assessed by the Positive and Negative Syndrome Scale (PANSS) and Eguma's Social Adjustment Scale (ESAS) at a 5-year followup evaluation. The subjects were divided into two groups according to their medication patterns determined at the assessment. Mann-Whitney V test revealed no significant differences in the PANSS scores between the treated group in = 22) and the nontreated group (n = 29), whereas a significant difference in the distribution of the scores was observed (Kolomorov-Smirnoff test, p < 0.05). Subjects in the nontreated group showed a greater tendency to be scored either high or low in the PANSS than did subjects in the treated group. Moreover, subjects in the nontreated group tended to be classified more often into the best or worst outcome categories when the ESAS was performed than subjects in the treated group (chi-square analysis, p < 0.05). In the present study, nontreatment may reflect a good outcome in terms of no requirement for continuing treatment but still be causally related to poor outcome in terms of absence of the necessary treatment. The results suggest the importance of therapeutic intervention for schizophrenia patients who have severe psychopathology without maintenance treatment in nonindustrialized societies.

“Made In China” Products and the Implication of Ethnic Identification Strength

This paper seeks to examine the effect of ethnic identification strength between the Malays and Chinese towards purchasing “Made in China” products. A quantitative approach by means of self-administered questionnaire was adopted. 252 Malay and 251 Chinese respondents’ data were collected from local institutions of higher learning. Independent sample t-tests and multiple regression analysis were used to look into difference and relationship pertaining to country of origin (COO) image, product knowledge, product involvement, information search and purchase intention. The findings show Malays and Chinese are different in terms of their perceptions towards COO image and product involvement. Moreover, COO image is found to be significantly different among Malays and Chinese with strong and weak ethnic identification. However, COO image is found to have no effect on information search and purchase intention although both ethnic groups are generally in favor of products “Made in China. ” Instead product knowledge and involvement are found to be essential. This study suggests that marketers and managers need to understand what is shared and what is not among Malays and Chinese in a developing and diverse society like Malaysia. Despite the effect of COO image and ethnic identification strength, product knowledge and involvement play pivotal role in understanding consumers today.
Influence of storage condition on seed quality of maize, soybean and sunflower.

The study was aimed to examine the changes in seed vigor and oil content in different genotypes of maize, soybean and sunflower over four years (20022006) in two type storage conditions differed in terms of air temperature and humidity: 25 °C/75 % and 12 °C/60 %, respectively. Affected by storage longevity, on an average, seed vigor decreased for 18,7% in maize and for 57,1 % in both soybean and sunflower, respectively. Seed oil content decreased for 1,12 % in maize, 2,27 % in soybean and 12,05 % in sunflower. Differences in seed vigor and oil content affected by storage longevity were significant among tested crops and genotypes into crop. Storage longevity was negatively associated with seed vigor and oil content. At storage conditions by 12 °C/ 60 %, decline of seed vigor was less for 17 % (maize), for 24 % (sunflower, soybean) and decreasing of seed oil content was less for 0.87 % (maize), 0.91 % (soybean) and 2,27 % (sunflower) than in storage conditions by 25 °C/75 %. In summary, the lowest seed quality losses were in maize, then in soybean and the highest losses were in sunflower. Decreasing seed quality losses is possible with providing suitable storage conditions, particularly for soybean and sunflower.
