Submitted for the MAR16 Meeting of The American Physical Society Fluorescence Intermittency and Nanodot Evolution in Graphene Oxide1 ANTHONY RUTH, Univ of Notre Dame, HAYASHI MICHITOSHI, National Taiwan University, MATTHEWMCDONALD, JIXIN SI, YURI MOROZOV, Univ of Notre Dame, PETER ZAPOL, Argonne National Laboratory, MASARU KUNO, BOLDIZSAR JANKO, Univ of Notre Dame — In recent experiments, micron-sized reduced graphene oxide (rGO) flakes were observed to exhibit strong photoluminescence intensity fluctuations, or blinking. Although blinking has been observed in a wide variety of nanoscale emitters, and striking universalities exist across these very different systems, rGO is the first quasi-two dimensional emitter that shows blinking. Despite the widespread presence of blinking at nanoscale, a microscopic mechanism behind this phenomenon remains elusive. Here we provide density functional theory results, analytical calculations, and Monte Carlo simulations to connect the fluorescence trajectories observed in the experiment to microscopic processes. Through Monte Carlo simulations of chemical processes occurring on the graphene oxide surface, we observe the formation and destruction of carbon nanodots. Finally, we use emission characteristics of carbon nanodots from Ab Initio methods to reconstruct the photoluminescence of the macroscopic flake. In particular, we are investigating whether fluorescence intermittency in reduced graphene oxide is an intrinsic optoelectronic property of the nanodot constituents or the result of reversible chemical processes capable of changing the size and number of graphene nanodots. 1This work was supported by a NASA Space Technology Research Fellowship Anthony Ruth Univ of Notre Dame Date submitted: 02 Nov 2015 Electronic form version 1.4


AIM To investigate the prophylactic effect of melatonin (MT) on immunological liver injury. METHODS The model of mouse immunological liver injury was induced by injection of bacillus calmette guerin (BCG) and lipopolysaccharide (LPS) from tail vein. The alanine aminotransferase(ALT), aspartate aminotransferase(AST), nitric oxide (NO) level in plasma, malondiadehyde(MDA) content and superoxide dismutase(SOD) activity in liver homogenate were assayed with different methods; Tumour necrosis factor α (TNF α) activity was determined by method of L929 cells line; Interleukin 1 activity was determined by method of thymocytes proliferation. RESULTS Immunological liver injury was successfully induced by BCG+LPS. MT(0 25,1,4 mg·kg -1 ) was found to decrease significantly the serum transaminase (ALT,AST) activities.However,MT at the dose of 1 mg·kg -1 was the most effective among the three doses. MT also decreased MDA content and improved reduced SOD level in liver homogenate. Furthermore, MT significantly reduced TNF α, NO and IL 1 levels in serum. CONCLUSION MT shows significant protective action on immunological liver injury in mice.


This study was designed to determine whether academic edu cational achievements of women inmates during incarceration had significant effects upon their subsequent recidivism. An experi mental group of 100 ex-inmates who had received the General Educational Development (G.E.D.) certificate while in prison was equated in terms of 14 personal and criminal factors to a control group of 100 ex-inmates who had not completed the G.E.D. pro gram. The groups were then compared in terms of recidivism rates. Although the proportion of non-recidivists was slightly higher for the G.E.D. group than for the control group, the difference was not significant at the .05 level of confidence. Thus, the hypotheses that successful participation in academic educational programs by women inmates reduces their subsequent recidivism was not sup ported.


Purpose: The treatments for congenital nasolacrimal duct obstruction range from minimally invasive to more invasive methods. Initially, clinicians select lacrimal sac massage with topical antibiotics application or early lacrimal sac probing. We studied if the characteristics of infants improved after lacrimal sac massage with topical antibiotic application. Methods: Two hundred thirty-four eyes of 204 patients diagnosed with congenital nasolacrimal duct obstruction from March 2001 to January 2007 were included. Excluded were infants who had obvious epiblepharon or eyelid abnormalities, tumors of the lacrimal system, or a history of trauma. Neonates less than 1 month were also excluded to rule out neonatal conjunctivitis. At the first visit, we recorded birth profile information such as gestational age, birth weight and height, onset time of symptoms, and post-conceptional age. We compared the results between the successful treatment group and failure group after lacrimal sac massage and topical antibiotic application. Results: One hundred twenty-three eyes showed improvement after conservative treatment (52.6%), and the infants included in the success group visited earlier and had lower PCA (P

Many Recommender Systems (RSs) rely on user preference data in the form of ratings or likes for items. Previous research has shown that item comparisons can also be effectively used to model user preferences and build RS. However, users often express their preferences by referring to specific features of the items. For instance, a user may like Italian movies more than Indian ones or like action-thriller movies. In this paper, we map such preferences over features to comparisons between items. For instance, when a user's favorite feature is `action', we then assume that `action' movies are preferred to some of the movies that are not `action'. In this work we effectively incorporate these feature based comparisons in a RS and show that such preferences can be effectively combined along with other item comparisons. Moreover, we also study the usefulness of the available features.


Among the variety of products for thermal insulatio n in industry the aerogel blankets have received significant attention because of their unique properties and wide range of applications. This paper presents the basic properties, fields of application and results of experimental study of Pyro gel XT, which is a type of high temperature aerogel blanket. It is formed of silica aerogel and reinforced with glass fiber batting. In comparison with traditional insulating materials Pyrogel XT is much more efficient thermal insulation with wide temperature range of application (-40÷650oC). It also has the lowest thermal con ductivity of any known solid material. Experimental investigation of thermophysi cal properties of Pyrogel XT was carried out by using traditional and modern res earch methods. The traditional method utilized a simplified single-plate Poensgen apparatus. The modern approach was performed on a Unitherm TM model 2022 thermal conductivity instrument which uses a guarded heat flow meter method ac cording to ASTM E1530 standard. Results obtained from both devices were co mpared and analyzed.

| We have investigated the protective effect of oral administration of the ethanolic extract of Bougainvillea spectabilis leaves against aflatoxin B1 (AFB1) induced hepatic injuries among male Swiss albino mice. AFB1 exposure has significantly increased (P< 0.05) the lipid peroxidase activity and decreased the activities of various antioxidant enzymes viz. superoxide dismutase (57.58%), catalase (24.14%), glutathione peroxidase (44.21%), glutathione S-transferase (44.07%) and glutathione reductase (13.51%). It also declined the level of ascorbic acid, reduced glutathione and protein contents by 47%, 34% and 24% respectively. It markedly decreased lipid peroxidation (TBARS level) with concomitant stimulation (P < 0.05) of antioxidants (enzymatic and non – enzymatic both). HPTLC analysis revealed availability of sufficient amount of flavonoids, alkaloids and phenolic compounds in the extract of B. spectabilis leaves might be responsible for the improved efficiency of antioxidant system and subsequent protection from aflatoxicity.


A series of water soluble N maleoyl chitosan was synthesized in an acid homogeneous solution. Their chemical structure were demonstrated by FTIR and UV spectra. The effects of the mole ratio of anhydride to amino group of chitosan in feed solution on the solubility, intrinsic viscosity() and the yield of product were studied. The results showed that the solubility of N maleoyl chitosan was greatly improved in water. The highest yield was obtained at 0 5 mole ratio of maleic anhydride to chitosan.


The paper at first systematically reviews the main Chinese and western merger motive theories and latest viewpoints. The differences lie in the three aspects of ultimate goal of mergers,importance of resources of transferrable listing qualifications,and maturity of investors. And there are two similarities,i. e., maximization of corporate or management interests and irrationality of investors between Chinese and western theories. The authors then point out the existing problems in the motive theories and development directions of theoretical researches.


Groundwater numerical simulation of groundwater flow has been widely applied in research on hydrogeological problems in mining areas,and the focus is on prediction of discharge.The invertion of hydrogeological conditions in mining areas is still at the exploration stage.According to the fact that we have no clear understanding of key hydrogeological conditions in the Makeng mining area,we take groundwater in the karst-fissured aquifer as a study object and establish a 3-D numerical simulation model.The model is identified and verified with groundwater dynamics and discharge of the mining area,and several major hydrological geological problems are inverted.The boundary condition,water filling sources,pathway of groundwater and recharge of the exogenous water are further examined.This method is also regarded as an exploration to the application of numerical simulation.

Magnetic properties of the two-dimensional t-J model are reviewed. Some of these properties are close to those observed in cuprate perovskites. In particular, the magnetic response of the model is characterized by the intensive peak at the antiferromagnetic wave vector and at some transfer frequency. The peak splits into several incommensurate maxima for lower and higher frequencies. We discuss mechanisms which are responsible for these peculiarities in the model, which might also refer to cuprates.


We propose and analyze the use of a clustering algorithm to group flight positions together as a component of algorithmic airspace partitioning. The clustering problem is formulated as a constrained clustering problem, and we present novel heuristics for this problem. A primary hypothesis of this work is that the clustering algorithm approach for airspace partitioning allows dynamic density (DD) metrics to be implicitly manipulated in the airspace partitioning process. The analysis results demonstrate the efficacy of the constrained clustering algorithm heuristics and the successful control of DD results in the generated airspace partition.


Starting-up time for acceleration is one of EV dynamic performance characteristics.This paper studies different control strategies effects on acceleration time in the process of acceleration from stillness,and gives the advice that we should properly select motor starting control strategy according to the request of starting-up time for acceleration.


Whereas the prudential supervision of credit and other financial institutions has been a core policy concern of the EU legislator in the aftermath of the 2008 Financial Crisis, the supervision of private sector entities within the European Anti-Money Laundering framework has been subject to less attention. However, on 20 July 2021, the European Commission intervened and published legislative proposals for two regulations and one directive, meant to boost the European response to the phenomenon of Money Laundering. This contribution – after having pointed out the shortcomings of the current legislative framework – pursues a twofold objective: first, offering an in-depth analysis of whether the Single Supervisory Mechanism, set up within the banking union for the purposes of prudential supervision, might be a useful precedent of Europeanisation to build up upon in matters of Anti-Money Laundering supervision, and second, commenting the possible approaches to be taken when setting up an EU level Anti-Money Laundering supervisor. The systemic cross-border importance of AML – beyond the euro area – warrants the establishment of a new EU agency specialised on AML, invested with more supervisory powers than EBA, ESMA and EIOPA and taking over the direct supervision of high-risk obliged entities, while indirectly supervising the remaining entities. It is argued furthermore that such institutional reform should necessarily be accompanied by the establishment of a Single Rulebook, which enjoys direct applicability across the EU.


Summary The heart rate of anesthetized golden mantled ground squirrels ( Spermophilus lateralis) falls from 372±20 to 37±9beatsmin 21 during hibernation at 7˚C body temperature. Heart rate in the hibernating animals often waxed and waned in a fashion that was not clearly linked to the breathing pattern. Similar observations have been made on unanesthetized ground squirrels. Under anesthesia, the effects of vagotomy were small in both euthermic and hibernating animals and led to a 6‐8% increase in heart rate. Vagotomy also eliminated the cyclic fluctuations of heart rate in hibernating animals exhibiting this phenomenon. The post-vagotomy heart rate exhibited by these individuals suggested that both sympathetic excitation and parasympathetic depression were involved in producing these cyclic changes. Vagal stimulation reduced mean heart rate by at most 60‐80% in euthermic and hibernating animals. The strength of the stimulus required to elicit a maximal response in the hibernating animals was 35‐45% greater than that required in euthermic animals. Comparisons of mean heart rates obtained from euthermic and hibernating animals which were vagotomized, intact or stimulated to produce a maximum bradycardia produced temperature quotients of 2.21, 2.15 and 2.31, respectively. In this species, both resting vagal tone and the effects of vagal stimulation decrease in parallel with decreasing temperature over the range studied.


Oil and gas reservoirs leak. As a result large quantities of oil and gas from these reservoirs reach the surface forming seeps. When visible with the human eye we refer to macroseeps, else to microseeps. Macroseeps, particularly offshore, have been extensively studied. Microseeps are less well studied. Seeps are relevant to the oil and gas industry as a potential source of information for exploration. In addition, seeps are a source of methane emission and as such contribute a large but yet un-quantified amount of this gas to the global budget. Methane is a greenhouse gas. Hydrocarbon microseepage gives rise to expressions at the Earth surface in form of: (1) detectable trace concentrations of gasses (mainly ethane and methane), (2) mineral alteration of soils, and (3) anomalous spectral response in vegetation. Off shore, oil macroseeps can be seen forming slicks on the water surface detectable using radar imagery. Within the water column, the upward seeping gas produces bubbles that can be detected using sonar. On shore, seismics provides a means of visualising subsurface chimneys along which oil and gas migrate to the surface. At the surface, geochemical soil gas analysis provides insights into the nature and composition of the gas. High spectral resolution spectroscopic measurements in the field and from airborne or spaceborne imaging devices may potentially be used to detect and monitor hydrocarbon microseepage using mineral alteration (detection) and gas emission (monitoring using emission spectra).

Twenty four young (mean age 29 2 years, range 25-35) and 21 elderly (mean age 66 5, range 60-80) healthy sub? jects collected their urine in timed aliquots over 24 hours. The elderly subjects had been selected for their fitness by clinical and laboratory examinations and all lived independently at home. Sodium and potassium excre? tions were reduced in the elderly subjects compared with the young subjects, potassium excretion considerably so. This was despite similar 24 hour urine volumes and total solute excretion by both groups. The ratios of rates of excretion of water, electrolytes, and solutes during the night to the rates of excretion during the day were found to be higher in the elderly than the young subjects. Reduced day to night ratios of urinary excretion may be partly responsible for complaints of nocturia and sleep disturbance in elderly people.


Antifriction behaviors of ZrO2/steel under high temperature are investigated in the present paper. An impressive low coefficient of friction (CoF) (around 0.1) has been observed in ZrO2/steel contact at the temperature of 900 °C. The presence of low CoF is only favored under high temperature and decrease of temperature provokes an increase of CoF. This low friction phenomenon is explained under high temperature and brings about the formation of iron oxides of the friction layer simulated by first-principles method to understand the role of oxidation and a transformation of major component in oxidation layers from α-Fe2O3 to γ-Fe2O3 which owns a layered structure. Benefiting from the essential low shear force among layered interfaces, high temperature low friction is realized.


Micro, small and medium enterprises (MSMEs) are considerably contributory to social and economic progress and prosperity through their entrepreneurial capacities and capabilities. However, they experience constraining challenges that importunately impair their abilities, failing to optimally engage themselves in the privileging opportunities around, particularly in the financial aspect. This paper aims to establish the financial factors affecting the financial performance of Philippine MSMEs whose audited financial statements are utilized to extract financial ratios needed for the study. It also aims to determine the factor structure that can explain the variation among these financial factors and to determine the cohesive cluster that can separate these financial factors. It employed multiple linear regression, factor analysis and cluster analysis in order to respectively achieve its objectives. It establishes that debt ratio, asset turnover and gross profit margin have a significant effect on return on assets. It further establishes that there are two significant factor structures, namely "Sustainability" ratios and "Efficiency" ratios, explaining the variation among these financial ratios. It furthermore establishes that there are two cohesive clusters, namely "good" ratios and "poor" ratios, separating these financial ratios. It suggests that MSMEs should remain self-sufficient and self-reliant, without unreasonably depending on debts, hence should adequately afford capital to finance their businesses. Further, they should optimally operate to generate sales by efficiently employing their resources. Furthermore, they should judiciously control costs, without compromising quality of their products and services, in order to increase their margin. They should reinforce their performance by regularly advancing their efficiency and sustainability. They should work well to sustain good ratios and improve poor ratios. Notably, this paper suggests that stakeholders sustainably support MSMEs in light of creativity and collaboration.

This letter investigates the influence of row wheat for azimuthal look angles on radar backscatter at L-, S-, C-, and X-bands. The radar backscatter was collected with full polarization (HH, HV, VH, and VV) and incidence angles (10°-70°) at different wheat phenological stages. Simultaneously, wheat parameters (biomass, canopy height, stem density, leaf inclination, etc.) and soil parameters (moisture and roughness) were measured to explain the influence based on radiative transfer theory. The research results show that, when the contribution of soil scattering dominates in total backscatter, the influence of row wheat on radar backscatter is varied with the electromagnetic wavelength and the visible soil contained in radar footprint area. When volume scattering contributes more in total backscatter, the influence of row wheat on radar backscatter mainly comes from leaf parameters and wheat geometric shape. Moreover, research results also show that azimuthal look angles affect radar backscatter much mainly for variable scattering cross section and leaf parameters. The research is helpful for cereal monitoring, modeling, and cereal parameter inversion from synthetic aperture radar images.


The design of high-frequency bipolar transistors with very low distortion is described. Simple expressions for distortion are used to select device parameters for the optimization of distortion performance. The effect of epitaxial-layer characteristics on device performance is considered in detail, and the importance of collector depletion in achieving low distortion is shown. The influence of device geometry on distortion is considered, and the degradation caused by MOS capacitance is illustrated.


The symmetry groups of double-wall carbon nanotubes (DWCNs) are the line and point groups for the commensurate and incommensurate walls, respectively. For the tubes with diameters between 2.8 Å and 50 Å all possible DWCNs are found. Among them all the 318 commensurate DWCNs are singled out and their symmetry groups are calculated. DWCNs are low symmetry objects with respect to the constituent single-wall tubes, and this symmetry reduction is described by the symmetry breaking groups. Both symmetry and symmetry breaking groups affect the physical properties of the DWCNs. While, e.g., quantum numbers and selection rules are related to the symmetry group, the low interaction between the walls is determined by the breaking group.


The overall goal of the criminal justice system is to ensure that perpetrators of crimes are duly punished and that victims of crimes are duly exonerated. As part of the effort to achieve this goal, the forensic disciplines have become very important in criminal investigations and prosecutions in identifying the guilty and in exonerating the innocent. There is a growing number of cases where people have been convicted based on a single piece of forensic evidence. However, some of the convictions have been found to be wrong, largely, due to the lack of adequate scientific validation of the forensic science methods. Some of these methods include latent fingerprint analysis, bite mark analysis, microscopic hair analysis and firearms identification. This article critically examines the application of forensic evidence in criminal prosecutions and highlights the dangers of convictions based on a single piece of forensic evidence. The findings of recent reports, such as, the National Academy of Sciences (NAS) 2009 Report and President's Council of Advisors on Science and Technology (PCAST) 2016 Report, confirm the critical role and broad scope of these forensic pattern-matching methods. The reports also indicate flaws that affect the accuracy of these methods, such as, inadequate scientific validation, coincidental results (erroneous match), human, laboratory and interpretive errors etc. Therefore, this article argues that the court should follow a cautionary approach when relying on a single piece of forensic evidence and that strong corroboration with other forms of evidence linking the accused to the crime should be required.


Early in the AIDS epidemic opportunistic lung infections, most notably Pneumocystis infection, dominated the clinical picture and were the most common cause of death in HIV-infected individuals. With the progressive development of effective antiretroviral treatments and prophylaxis against Pneumocystis, the prognosis in HIV/AIDS has improved dramatically with median survival now greater than a decade. However, lung infections from opportunistic, as well as typical bacterial pathogens remain a major cause of morbidity and are still the leading cause of death from HIV/AIDS. In addition, as the survival of infected individuals has increased, it is becoming apparent that other more-chronic lung diseases, including emphysema and cancer, are more common in these individuals. Although the mechanisms by which HIV/AIDS increases the risk of both infectious and noninfectious lung diseases are still being investigated, there is emerging evidence from clinical and experimental studies that HIV causes oxidant stress w...

It is well known that cataract is one of the leading causes of blindness. At present, surgery with the use of an intraocular lens is the only method of cataract treatment. Along with great progress in cataract surgery, the conception is changing from the vision resuming surgery to the refractive surgery. The aim of the surgery is not only to extract the cataract but also to restore the nearly normal visual function. With the perfecting technique of surgery, doctors could pay more attention to the patients' feelings and the visual experiences during the surgery besides the better visual results. All of these make the cataract surgery more humanity.


A miniature planar monopole ultrawideband (UWB) antenna with a wide bandwidth is described. The radiator and ground plane are etched on 11mm×15 mm FR4 printed circuit board. Here, a staircase profile is made at the bottom and top parts of the radiator and ground plane respectively, to improve the impedance matching of the antenna. The proposed antenna has a useable fractional bandwidth of over 120% (7.5-30GHz for VSWR <; 2.5). The measured results show good far field radiation properties of the antenna.


Summary

The seasonal variation in the organic- and nitrate-nitrogen content of Gezira soil under irrigated rotational cropping has been studied over six successive years. Accent so far has been placed on the cotton phase of the rotations and statistical analysis of the results has shown that the organic-nitrogen content of the soil is not increased by rotational cropping beyond an equilibrium value which is presumably a function of the environmental conditions.

Increase of organic nitrogen in Gezira soil appears to be a function of seasonal conditions. Loss of organic nitrogen in marked excess of what could conceivably be explained by crop uptake is a definite feature. The loss occurs gradually throughout the whole season, giving a minimum organic-nitrogen content in the soil during the hot dry period of February to May.

Accumulation of nitrate-nitrogen, on the other hand, is dependent on the nature of the rotation and the period of the year. Nitrate accumulates at the beginning of the rainy season when it is rapidly leached to lower soil depths; it also accumulates on the bare fallows during the hot dry season. This latter finding is in accord with the statements of other workers.


A large number of prekindergarten programs (i.e., Head Start) have emerged throughout the nation to alleviate the imbalance in terms of intelligence scores, school readiness, and achievement of children between the white middle-class and the low income racial minorities. These prekindergarten programs require systematic, reliable, and valid evaluations. I n addition to these requirements, the evaluations must also be able to be administered in a short period of time and be interesting to the children. Intelligence test scores have shown a demonstrable success in predicting school achievement (Anastasi, 1969; Lesser, Fifer and Clark, 1965). As Kohlberg and Zigler (1967) have noted, despite the criticisms leveled against the I& measure, a child's I& score obtained in a standard situation has more behavioral correlates than any other psychological measure. A wealth of reliability and validity information exists on the Stanford Binet Intelligence Test, Form LM, but it fails to meet the two additional criteria of short administration time and interest for many young children from the lower socioeconomic level (k., Mexican-American). It is for this reason that researchers have used alternative tests, i.e., Peabody Picture Vocabulary Test (PPVT) , Dram-A-Man (DAM) , Children's Embedded Figures Test (CEFT), (Hodges and Spicker,


The strategy of the nervous system to activate agonist muscle(s) appears to differ substantially between eccentric versus isometric and concentric contractions1,2,3 . Previous study reports have indicated that in untrained individuals the muscle is not fully activated during eccentric contraction despite a maximal volitional effort (MVC). More specifically as pointed out by Simon Barrué-Belou.


This paper describes a simple and convenient approach to synthesize large amounts of ZnO nanosheets, which are suitable for producing a key component, i.e., colloidal nanoink, of printed ultraviolet photodetectors. ZnO nanosheets are produced by atomic layer deposition, where a three-dimensional polymer sponge with a large specific surface area is used as the template. Systematic studies including scanning electron microscopy, X-ray diffraction, and transmission electron microscopy reveal that the synthesized ZnO nanosheets have a good crystalline quality and mechanical flexibility. After dispersing ZnO nanosheets in a solvent to form a stable and colloidal nanoink, an ultraviolet photodetector is demonstrated through the printing method. Such a printed ultraviolet photodetector that utilizes ZnO nanosheets as the functional materials exhibits a high responsivity of ∼148 A/W and a response time of 19 s. Our present study may provide a practical method to produce large amounts of functional nanosheets for printing electronics, which paves the way for developing high-performance, low-cost, large-area printed, and flexible electronics.


Design concepts, engineering specifications, and performance test results are presented for a compact magnetic field dosimeter that is suitable for monitoring personnel exposures to steady‐state and time‐varying magnetic fields. The battery‐operated dosimeter contains thin‐film Hall sensors that record the magnetic induction (B) along three orthogonal axes. The Hall generators are operated in a pulsed mode, and the time rate of change of the magnetic induction (dB/dt) is determined for values of B recorded during consecutive sampling intervals (typically 75 ms). The pulsed mode operation also serves to reduce battery consumption. The dosimeter contains a programmable microprocessor‐based logic circuit and 4096 12‐bit words of permanent and random‐access memory. Stored parameters include: (1) average values of B and dB/dt during a preset time interval (typically 5 min); (2) peak values of B and dB/dt during the preset interval; and (3) the number of times that specified threshold levels for these parameter...


In 1947 Alden showed that the quantity of osmiophilic fat in the uterine epithelium of the rat followed a cyclic variation which was related to the ovarian cycle. Minimal amounts of fat were present during the estrous phase of the cycle and maximal amounts appeared in diestrus and early pregnancy. Treatment of spayed animals with estrogen and progesterone modified uterine fat, indicating that these hormones are primarily responsible for the observed changes in cycling animals. Similar findings have been reported for the mouse (Bourg, '29), guinea pig (Nicol and Snell, '55; Burgos and Wislocki, '56) cattle (Skjerven, '56) human (Gillman, '41 ; Page et al., '51) and rabbit (Gilbert, '42). As pointed out by Alden ('47) it is unlikely that osmiophilic epithelial fa t represents the total intracellular fa t of the uterus, since it is known that fa t bound to proteins is not visibly colored by osmication or fat-soluble dyes. I n confirmation of this conclusion, Berg ( %), using the benzpyrenecaffeine technique for "masked" lipids, was able to demonstrate nearly as much lipid in the endometrial stroma as in the epithelium of the mouse uterus.

The upshoot and downshoot in Duane's retraction syndrome is believed to be related to a leash effect from the lateral rectus muscle. When the eye is rotated into the adducted position, the lateral rectus muscle slips over the globe, producing the up-and downshoot on adduction. The splitting of the ends of the lateral rectus into a Y configuration prevents the rotation of the globe up or down by stabilizing the muscle's position on the eye. Three patients with Duane's retraction syndrome demonstrated abnormal vertical movement on adduction and underwent a Y-splitting on the lateral rectus. In all patients, marked decrease in the up-and downshoot is noted after surgery.

New aeromagnetic data collected at 400 m line spacing in the area of the Naver and Ste. Marie plutons, central British Columbia, provide images of the magnetic field at sufficiently high resolution to examine finer elements of the bedrock geology, which is largely hidden by ubiquitous Quaternary glacial cover. The data offer a wealth of information on the internal structure and lithological variations of many units defined by 1 : 250 000 scale geological mapping. Complementary airborne radiometric data collected in the same survey contribute to the analytical process and to an evaluation of the mineral potential in the area. One of the principal outcomes of the analysis is a picture of the detailed structural fabric of the area provided by images of vertical derivatives of the magnetic field that proxy as predictive maps. This fabric is an important framework for developing exploration strategies. Patterns and other characteristics of the magnetic field have been used to revise positions of some geological boundaries, delineate domains within the Naver and Ste. Marie plutons, map faults, and speculate on sources of magnetic anomalies having no apparent link with mapped geology, some of which are probably intrusions. Radiometric data have been used to supplement the magnetic interpretations in some cases, but their main utility has been in evaluating the area for its potential for copper-porphyry-type deposits. The characteristic potassium enrichment associated with these deposits can be manifested in radiometric data as potassium highs and, critically important, Th/K lows. Several such features of interest are discussed. An important conclusion based on radiometric data is that glacial transport in the area has been minimal, probably no more than a few kilometres. The significance of this, in this area of widespread glacial cover, is that radiometric signatures can be confidently interpreted to represent bedrock directly below them. The same confidence can be applied to geochemical data derived from glacial tills, and this is of considerable significance for mineral exploration.


Non-dominated Sorting Genetic Algorithm-II (NSGA-II) is applied for solving Combined Economic Emission Dispatch (CEED) problem with valve-point loading of thermal generators. This CEED problem with valve-point loading is a nonlinear, constrained multi-objective optimization problem, with power balance and generator capacity constraints. The valve-point loading introduce ripples in the input-output characteristics of generating units and make the CEED problem as a nonsmooth optimization problem. To validate its effectiveness of NSGA-II, two benchmark test systems, IEEE 30-bus and IEEE 118-bus systems are considered. To compare the Pareto-front obtained using NSGA-II, reference Pareto-front is generated using multiple runs of Real Coded Genetic Algorithm (RCGA) with weighted sum of objectives. Comparison with other optimization techniques showed the superiority of the NSGA-II approach and confirmed its potential for solving the CEED problem. Numerical results show that NSGA-II algorithm can provide Pareto-front in a single run with good diversity and convergence. An approach based on Technique for Ordering Preferences by Similarity to Ideal Solution (TOPSIS) is applied on non-dominated solutions obtained to determine Best Compromise Solution (BCS).


Electroprospecting works have been performed over one of the blocks in the Southeast Asia. Two techniques were used: Transient Electromagnetic Soundings in Time Domain (TEM) and Induced Polarization Electromagnetic method (EM-IP). The objective is to conduct a comprehensive study of the sedimentary cover using TDEM. This includes mapping of zones with potential reservoirs properties from TEM, and to qualify these areas with Induced Polarization (IP) anomalies, usually related to presence of hydrocarbon system. From TEM investigations was found that sediments of surveyed area are highly conductive. Total conductivity exceeds 2000 S. Furthermore, the high noise level is common for the survey area. The most influence on the EM data has 50 Hz noise due to its unstable parameters: amplitude and frequency. Nevertheless EM technique has shown sensitivity to geoelectric parameters changes to the depth up to 4 km. It was possible with development of special algorithms of EM signals processing. Overall investigations show possibility of TEM and EM-IP application even in highly conductive environment and complicated noise situation.

A type of transformer with reduced iron loss, which is excited by a semirotating magnetic field, has been investigated. Factors (method of excitation and slits in the core) affecting iron losses are examined. The iron loss of this type of transformer can be reduced below the material loss as measured for normal AC excitation by introducing a slit which cuts the eddy current path, and by improving the method of excitation. >


Two-photon radiative decay process $J/\psi \to 2\gamma+hadrons$ is studied, and the main contribution processes $J/\psi \to 2\gamma + g g g$ and $J/\psi \to 2\gamma + q \bar{q}$ are calculated. With the specific condition at the BESIII, this rare decay process and the main background process $e^{+} e^{-} \to \gamma \gamma + hadrons (q \bar{q})$ are investigated. The results show that the ratio of signal to background can reach 1.24 with the optimized selection criteria at the BESIII. In addition, a few distributions of the signal and background are presented. All the results show that the signal is large enough to be measured in the experiment.

This paper describes the development of the hybrid fault current limiter and interrupting device (HCLID) which can be used successfully as a fast short-circuit protection means for low voltage AC industrial installations. The main components of the HCLID are a solid state commutation circuit that can supply a counter current injection from a stand-by pre-charged capacitor, saturable core reactor as the limiting impedance and fast mechanical contact switch all connected in parallel. Through this study, we can present a significantly improved and simplified approach that replaces the half-controllable silicon-controlled rectifier (SCR) in the commutation circuit with self-turn-off device such as integrated gate-commutated thyristor (IGCT). The use of highperformance semiconductors (IGCTs) as the commutating affords reduced recovery voltage, reduced losses, improved reliability and dynamic performance, and fast switching time (in μs). The new approach involves a fault detection using rate of current rise rather than the current magnitude and a time delay operating characteristic based on Piecewise Linear Electrical Circuit Simulation (PLECS) program. The control method is very simple. Simulations carried out during the research. Simulation results proved the practicability and validity of the new HCLID.


Introduction: Health behaviors including sleep, physical activity (PA) and sedentariness directly and indirectly affect CVD risk. Risk of CVD mortality and morbidity decreases with increasing leisure time PA. Sleep length deviant from population mean relates to increased CVD risk. Sleep quality and circadian preference are suggested to associate with CVD risk and metabolic risk factors. It is unclear how PA modifies health risks of poor sleep and vice versa. Higher PA may improve sleep and poor or short sleep may reduce PA. Our aim is to recognize people with the same profile of PA, sedentariness and sleep and to study if these subpopulations differ in their CVD risk. Material and methods: The National FINRISK 2012 Study comprised a stratified random sample of 10 000 Finns, aged 25 to 74 years, who participated in a health examination and filled in questionnaires. Participation rate was 65% (3041 men, 3383 women). We calculated the Framingham 10 year risk score for participants initially free from CVD and...


Fine needle aspiration (FNA) diagnoses are usually confirmed via surgical pathology or via evaluation of clinical outcomes. However, such confirmation may not occur for patients who die shortly after FNA, and autopsy may be a useful quality assessment tool in these cases. Also, there is little data investigating the relationship between FNA and mortality. We sought to demonstrate the autopsy as a quality assessment tool for the FNA and assess the contribution of FNA to mortality in patients who die soon after the procedure.


For a long time,the contradictory feature of the female images in Humboldt's Gift and its causes are nearly ignored. From the feminist point of view,this paper studies the three major female images Kathleen,Denise and Renata,who are brave to pursue freedom and to construct their identities,by variously mingling the elements of "angles"and "madwomen". And we find this contradictory feature is caused by both the inherent consistency between"angles"and"madwomen"and Bellow's contradictory attitude toward feminism.


Based on the flexural differential equation of elastic piles,a simplified analytical solution of an axially loaded single pile subjected to lateral soil movement is put forward.In this solution,the subsoil is simulated with the Winkler's spring model and a two-stage method proposed by Poulos is introduced to establish the equations.The flexural differential equation is solved by the finite difference method,which is more convenient and more adaptable for layered foundations.The method is validated by some typical examples calculated by other methods.Results show that the interactive effects between soil movement and the axial load have some influence on the behavior of piles by generating additional displacements and bending moments which may be quite different according to the properties of both piles and soil as well as boundary conditions of pile head.The boundary conditions of pile head have obvious influence on the distribution of displacement and stress of pile.An effective restrain at the head of pile can reduce the negative couple effects of axial load and lateral soil movement acting on the pile.The present method can be applied to practical engineering.


days, P = 0.006), duration of Intensive Care Unit stay (11 [6–13.5] vs. 15 [14.25–23] days, P = 0.006) and duration of hospital stay (11 [7–13.5] vs. 22 [15.75–43.25] days, P = 0.006). The difference of time taken for seizure control between the groups was trending toward significance (4 [3–4.5] vs. 5 [4–12] h, P = 0.091). Survival curve analysis showed a significant difference between the groups for stoppage of infusions due to either hypotension or inadequate seizure control, with midazolam recording earlier infusion discontinuation (Breslow's test, P = 0.005) [Figure 1]. Termination of infusions due to successful seizure control did not show any significant difference (P = 0.609). Conclusion: Despite the limitation of small sample size, outcomes seem to be better with propofol infusion rather than midazolam. Future studies with larger sample sizes are likely to validate this finding.


Background/Aims: Patients with postoperative pulmonary complications after esophagectomy often have increased mortality. The purpose of the study was to examine the efficacy of preventing postoperative pulmonary complications by an intensive preoperative respiratory rehabilitation (PR) program for esophageal cancer patients. Methods: This study was a prospective randomized controlled study. Thirty patients in the PR group and 30 patients in the no preoperative respiratory rehabilitation (NPR) group were included. The PR group received preoperative rehabilitation for more than 7 days, while the NPR group did not receive any preoperative rehabilitation. All patients underwent postoperative rehabilitation from the first postoperative day. The postoperative pulmonary complications were evaluated using the Clavien-Dindo classification (CDC) and the Utrecht Pneumonia Scoring System (UPSS). Results: The CDC grade in the PR group was significantly lower than that in the NPR group (p = 0.014). The UPSS score in the PR group was significantly lower than that in the NPR group at postoperative day 1 (p = 0.031). In the multivariate analysis, NPR was an independent risk factor for postoperative pulmonary complications greater than CDC grade II (OR: 3.99, 95% CI: 1.28-12.4, p = 0.017). Conclusions: This study showed that the intensive PR program was capable of reducing the postoperative pulmonary complications in esophageal cancer patients.

Abstract— The social network embodies real-life social graphs. Detecting communities or clusters from these graphs is an ill-posed difficult task. The communities are identified using the adjacent nodes that have shared edges and similar features. One of the principal concerns after community detection is to identify the active nodes in a network who attend several communities. So, finding communities that are overlapped in a social network is an important topic in social network analysis. This paper introduces an algorithm based on the multi-agent particle swarm optimization. The proposed algorithm detects overlapping as well as non-overlapping communities. Following the detection of overlapping communities, this algorithm can identify those nodes leading to overlapping, and ultimately it can determine the affiliation ratio of each node to the given community. The algorithm uses a special type of coding to identify the number of communities without any prior knowledge. In this method, the modularity measure is used as a fitness function to optimize particle swarm. Several experiments show that the proposed algorithm which is called Fuzzy Overlapping Community Detection based on MultiAgent Particle Swarm Optimization (FOCDMAPSO), is superior compared with four other competitive algorithms. This algorithm is implemented over six well-known datasets and five LFR datasets in the literature. Our algorithm is capable of detecting nodes in overlapping communities with high accuracy. Furthermore, the proposed algorithm can detect the affiliation percentage of each node that leads to overlapping communities which is a novel feature in the area of the social network.


The berries of Pimenta dioica (L)Merril (FamilyMyrtaceae) are commonly known as allspice in culinary. The natives of Kerala andMangalore use Allspice leaves as medicine for pain, arthritis, fever and stress. In all these pathological conditions oxidative stress is one of the causes, hence we tried extract the leaves for in vitro antioxidant activity. 20% yield of alcoholic extract obtained from the dry leaves showed total phenolic content (TPC) equivalent to 20 ± 1.63 mg/g of the dry leaves powder. The extract showed significant antioxidant activity by reducing power, DPPH radical scavenging and Lipid peroxidation assays. The antioxidant activity was proportional to the total phenolic content in the leaves.
The high content of phenolic antioxidants in the extract urged us to screen for hepatoprotective activity in carbon tetrachloride (CCl4) intoxicated Wistar rats. The oral
doses (250, 500, 750 mg/kg/day) showed statistically significant protection of liver when investigated by histopathological and biochemical parameters


Disk (streak and plate) and liquid (turbidity) methods have already been reported by many workers as modifications of the procedure of "rec-assay".1* However, these methods are complicated, time-consuming laborious and of low sensitivity. So we improved a method for the determination of minimum inhibitory concentrations (MICs) using a pH indicator. This method, which is superior in cost, simplicity of handling, and reproducibility, is a kind of quantitative liquid method using spores of B. subtilis in modified media with glucose. MICs of various chemicals for growth of H17Rec+ and M45Rec~ strains in the wells of a microtiter plate were easily established by adding bromthymol blue (BTB) as a pH


This article is an extended response to the exhibition "Lace in Fashion" at Bath Fashion Museum (4th February 2017-1st January 2018). It argues that the exhibition is the "jewel in the crown" of all 2017 fashion exhibitions on view on this side of the Atlantic. What makes the Bath exhibition stand out as a good fashion exhibition lies in its multi-narrative approach to lace and lace making in historic and contemporary fashion. It is in the strategic curatorial selection of objects, the trajectory of visually striking vitrine displays, the detailed and informative captions that prompt rather than limit thinking, inviting international and national visitors into a wide range of meanings, interpretations and those unpredictable spaces of the imagined past and lived present where personal memories resonate and roam freely, creating for visitors a rich emotional and intellectual experience in a traditionally framed, object based, visitor centred, exhibition.


In the paper, we generalize a two-action (yes-no) model of influence to a framework in which every player has a continuum of actions and he has to choose one of them. We assume the set of actions to be an interval. Each player has an inclination to choose one of the actions. Due to influence among players, the �?nal decision of a player, i.e., his choice of one action, may be different from his original inclination. In particular, a coalition of players with the same inclination may influence another player with different inclination, and as a result of this influence, the decision of the player is closer to the inclination of the influencing coalition than his inclination was. We introduce and study a measure of such a positive influence of a coalition on a player. Several unanimous influence functions in this generalized framework are considered. Moreover, we investigate other tools for analyzing influence, like the concept of a follower of a given coalition, its particular case - a perfect follower, and the kernel of an influence function. We study properties of these concepts. Also the set of �?xed points under a given influence function is analyzed. Furthermore, we study linear influence functions. We also introduce a measure of a negative influence of a coalition on a player.


Ecological space in a densely urbanized region plays a very important role in its development. Therefore, a scientific evaluation of ecological spaces in a densely urbanized region is the main prerequisite for corresponding ecological space planning. Taking the Wu-E-Huang-Huang Metropolitan Interlocking Region as the study area, the paper selects six types of ecological factors, including the location index, land status, terrain conditions (elevation, slope), hydrological conditions (rivers, lakes), landscape value, and road traffic. By using a single factor evaluation and a multi-factor comprehensive evaluation method involving GIS, the paper presents an evaluation of the ecological space conditions of the Wu-E-Huang-Huang Metropolitan Interlocking Region. In line with the result, the ecological environment of the region is divided into four levels: highly sensitive areas, sensitive areas, weakly sensitive areas and insensitive areas. On this basis, the underlying problems and mechanisms are explored further.


Redshift observations of 30 clusters in the direction of the Sextans-Leo supercluster candidate are reported. The observations are part of a program which involves mapping the universe's large-scale structure, and include North Galactic Cap Abell clusters, Abell clusters that have only been partially observed, and unmeasured poor Zwicky clusters. Three large superclusters are identified in the region which surround an apparent void that is open on one side towards the galaxy void in Bootes. The minimum dimensions of the void are given, and one of the superclusters is identified based on it resemblance to Coma/A1367. The emptiness of the Bootes void and the void of Bahcall and Soneira (1982) are redefined by the positions determined for five clusters observed in other portions of the northern cap. Additionally, some galaxies appear to be within the bounds of the Sextans-Leo void. 23 refs.


At present,many serious diseases are found on the long span continuous rigid frame bridges.The common method of external pre-stressing doesn't work well.Enlightened by the concept of the partially cable-stayed bridge and the cable-held bridge structure system, three types of new structure systems are designed to strengthen the old rigid frame bridges.At same time,their mechanical characters and effects are discussed and compared.And it will be the reference for the same kind of bridge on strengthening design.


In our study, we focused on the assessment of four bankruptcy prediction models, to figure out which model is most appropriate in the conditions of the Slovak business environment. Based on the previous research within the Slovak conditions, we set a portfolio of 4 models to be assessed: Altman model (1984), Ohlson model (1980), indexes IN01 and IN05 that were validated on the sample of 700 Slovak companies. Based on previous studies we expected that IN indexes are superior to Ohlson and Altman model. The excellency of our research lies in validation and assessing the accuracy of bankruptcy prediction models at three levels: the overall accuracy, accuracy of the bankruptcy prediction, and the non-bankruptcy prediction accuracy. This analytical structure enables to look at the topic more complexly and to increase the objectification of accuracy of analysed models. Based on the results, we showed that Ohlson model is not applicable to predict bankruptcy in the Slovak conditions as reached the lowest bankruptcy prediction ability even if has high non bankruptcy prediction ability. On the other hand, we have confirmed our expectation about the bankruptcy prediction ability of index IN05, that is proven to be superior to Ohlson and Altman model and so is the most appropriate model for Slovak business environment.


This paper is a review of nepsis according to the Philokalia Fathers.The Philokalia is a collection of texts written between the fourth and the fifteenth centuries by spiritual masters of the Orthodox Christian tradition. After a person believes and is baptized in Christ, he has put on Christ and become a new man. He grows up to be like Christ by renewing his heart and nous. The Philokalia fathers concern on the renewal of the nous. And the most important way to renew the nous is by controlling the nous with all nepsis (prosoche) and praying (proseuche). The Philokalia fathers emphasized the importance of nepsis because they believed that the arch-enemy of the soul is a certain kind of thought which they described with the word logismoi.Nepsis is the guarding of the heart and nous from logismoi. Nepsis and prayer belong together. Nepsis is the mother of prayer.


Based upon two personal beliefs, with regard to teaching that firstly "teaching is helping others to discover" and secondly that "assessment is a necessary inconvenience", a method has been developed in teaching Fluid Dynamics to undergraduate students, in a Mechanical Engineering Course. The main goal of this method is changing from a traditional theoretical approach of teaching "what is in the book" to a much more practical confrontation between theory and what can be found in laboratory experiment. The program contents are covered by four laboratory apparatuses: • Reynolds experiment, • Head losses in tubes, • Hydraulic turbines, • Centrifugal pumps, which are presented to all the students during a particular class so they can prepare for their next return to the laboratory, now organized into small groups. Meanwhile, each group must define their specific objectives and work planning, so the students can accomplish the experiments off-line, with the laboratory supervisor's eventual help and subsequent report must be written within a determined period. The main results achieved a success rate which has risen from about 50%, of the evaluated students before setting up the method to 70%, but keeping the same lecturer, i.e. the same quality demand.Copyright © 2006 by ASME


This article evaluates and describes the presence, extent and locational impact of residential second home ownership in the Canadian Rocky Mountain town of Canmore, Alberta in response to planning needs and requirements. This research includes the results of two studies that provide a temporal view of second home retirement owners and amenity attributes through the use of social survey data, multivariate analysis and geographic information system (GIS) visualization. One assumption of second home research focuses on retirement migration towards permanent residency in many amenable environments. The Canmore example illustrates problems with such an assumption and shows that international retirement markets can differ from domestic ones with subsequent differences in ownership patterns, leisure and local participation behaviours, and planning needs. Revealed are landscape attributes and sociocultural amenities important to second homeowners and the larger community. The research outcomes add understanding about international second homeowners in a small Canadian town and how group differences or similarities may translate for future second home retirement plans within this Rocky Mountain gateway to Banff National Park.


The technique of cavity ring‐down (CRD) spectroscopy is particularly useful for measuring absorptions of very weak optical transitions. We have in this manner investigated the 40 950–41 300 cm−1 region in O2, where only absorption in the O2(A 3Σ+u–X 3Σ−g) 11‐0 band had been previously identified. Five new bands have been discovered in this range—the A′ 3Δu–X 3Σ−g 12‐0 and 13‐0 bands, the c 1Σ−u–X 3Σ−g 17‐0 and 18‐0 bands, and the A 3Σ+u−X 3Σ−g 12‐0 band. The origins of the F1 and F2 components of the latter lie only 7 cm−1 below the lowest dissociation limit, and 15 lines have been identified. No F3 levels were observed; apparently all are above the dissociation limit. The high instrumental sensitivity of the CRD technique has allowed observation of weak lines of the A–X 11‐0 band, and 12 of the 13 branches have been identified and their intensities measured. A very low upper limit has been set on the intensity of the thirteenth branch, Q13. We find 107 unidentified lines in the region, the stronger ones ...


It is my pleasure to be the guest editor for the special issue focused on "Effect of epi-drugs on epigenetic modifications induced by environmental pollutants: implications for the pathophysiology of cancer and endocrine/metabolic diseases".

We are now living in the "epigenomic era" and are faced with a growing number of information about all the DNA-external factors that control gene expression of regulatory proteins. Most epimutations, including changes in DNA methylation, histone modifications, and microRNA levels, translate into either up-regulation or silencing of gene expression which, in turn, may predispose the organism to mutational events, reduced ability to repair DNA damage, increased genomic instability, altered cellular response, and reduced apoptosis.

Over the last decades, rapidly increasing evidence has connected environmental pollutants with epigenetic variations that may occur in a wide spectrum of diseases, including a variety of tumors and metabolic disorders. For these reasons, several clinical trials employing epi-drugs are underway or planned especially in areas exposed to environmental contaminants. Agents regulating histone deacetylases (HDACs), DNA methyltransferases (DNMTs), or miRNA expression profiles are proving to represent a good alternative for treating pollutant-induced diseases.

This special thematic issue takes into account: i) the epigenetic alterations induced by environmental chemical exposures and the underlying mechanisms; ii) their impact on human health; iii) the association with carcinogenesis, deregulation of cell cycle and apoptosis, altered mitochondrial function, energy metabolism, and impairment of the development process; iv) the biomarkers relevant in establishing the environmental health risk and response to treatment.

The data reported in this issue will give opportunities, challenges and future directions for epidemiology research in environmental epigenomics coupled to neoplastic, metabolic, and developmental diseases. Understanding the nature and the role of environmental pollutants on the epigenetic interactions and assessing correctly the risk of incidence of severe conditions that threaten the health and life expectancy represent a major challenge for basic and translational research. These acquisitions will further strengthen the precondition for the development of therapeutic strategies aimed at reversing the epigenetic damage induced by environmental pollutants.


Nowadays, based on the advancement of IT techniques, innovative products combining IT techniques to PA system are developing. In this paper, we presented the hybrid mixer controller for digital PA system. We develop the integrated mixer controller which includes the digital mixer composing an existing digital PA system and function of digital integrated controller. Developed integrated mixer controller consists of multichannel mixer function with 16 audio input channels, 8 output channels. And, it has an equalizer for processing digital audio signal, matrix and limiter. Also, the developed controller has some features such as internet connection for controlling of overall PA system and remote monitoring of mixer process condition.


Factors influencing the plaque formation by the double-layer method were studied with phages of Lactobacillus acidophilus. Factors influencing the EOP were as follows; pH and Cat concentration of medium, age of indicator cell, incubation temperature of plate, and addition of some reducing compounds (ascorbate, cysteine and thioglycollate) to medium. Factors influencing the size of plaque were as follows ; pH of medium, agar concen tration and amount of overlayer, number of indicator cell, incubation temperature of plate, and addition of some reducing compounds (ascorbate, cysteine, formate, sulfide and thioglycollate) to medium. As a result of these findings, standardized conditions for plaque formation procedure were determined. (Received October 7, 1968)


Anexcellent-qualitysetofimagesofthe1993Jovian South Equatorial Belt (SEB) revival are shown and discussed. For the rst time, this major SEB event was recorded since the very early stages of its development to its end at a variety of wavelengths from the ultraviolet to the near-infrared region of the spectrum. Our analysis supports, at least for the locus B, the Reese theory of the presence of three sources uniformly rotat- ing with respect to System III from which the SEB disturbances develop. Other Jovian features were also present in these im- ages, such as the activity in the South Temperate Belt or the presence of the so-called methane spots, which are shown to be photometrically analogous to the Great Red Spot on Jupiter. A general characterization of all the Jovian regions at the time of the South Equatorial Belt disturbance is done by comput- ing the limb darkening coefcients as a function of latitude and wavelength. This provides a useful reference to compare with other future measurements. The limb darkening coefcient at the brightest spot associated to the SEB event in April shows a different behaviour in its wavelength dependence as compared to all the other Jovian regions, a result that would imply a dif- ferent particle loading and/or particle size distribution in those regions as a consequence of vigorous dynamics.


Technological improvements such as virtualization, deduplication and advances in compression technology, as well as improvements in content security have reduced the costs while improving performance levels and trust in today's data centers. This, in addition to the growth in thin client devices such as smart phones and tablet computers, has led to increased use of digital storage in the cloud. At the same time the pending saturation of many internet and mobile networks, non-scaling content distribution networks, increasing content resolution and quantity and slow or intermittent internet connectivity for many users hinders the more widespread adoption of cloud based content. This talk will explore developments and drivers for both personal and Internet cloud storage and local storage in today's changing storage hierarchy and make projections on changes expected in the future enabled by more or less ubiquitous content and social interaction and ever smarter consumer and computer products.


This report describes a study design permitting a scientifically defensible evaluation of the impact of the School Breakfast Program (SBP) on learning and cognitive development among children. Following presentation of a literature review and conceptual framework of the SBPlearning relationship, four alternative designs for measuring this relationship are proposed and assessed, including: (1) the design for an experimental evaluation of the impact of the universal-free SBP; (2) an experimental design involving random assignment of classrooms into the SBP among schools applying to participate in the program for the first time; (3) a nonexperimental design involving analysis of Early Childhood Longitudinal Study (ECLS) data; and (4) a nonexperimental design involving analysis of forthcoming National Health and Nutrition Examination Survey (NHANES) data. Among these alternatives, the ECLS-based design (with supplemental analysis of 1988-1994 NHANES III data) was selected as most promising, and the report presents further details concerning this design.

Based on the results of the treatment research analysis using the Make A Match cooperative learning model assisted by video learning in the experimental class is better than the conventional learning model in the control class.


Abstract The effects of salinity and temperature on the photosynthetic and growth performance of the seagrasses Cymodocea nodosa and Ruppia cirrhosa were studied to understand their local seasonality and distribution. Cymodocea nodosa shoots were collected from Cape Vrasidas, and R. cirrhosa shoots from the coastal lagoon Fanari, all from the Eastern Macedonian and Thrace Region, Greece. Effective quantum yield (ΔF/Fm′), leaf chlorophyll-a content (mg g−1 wet mass) and growth (% of maximum) were tested at different temperatures (10–40°C) and salinities (5–60). The results showed that: (a) R. cirrhosa was more euryhaline (5–55/60) than C. nodosa (10–50), (b) the upper thermal tolerance of C. nodosa (34–35°C) was higher than that of R. cirrhosa (32–34°C), (c) C. nodosa could not tolerate 10°C, whereas R. cirrhosa could, and (d) the growth optimum of C. nodosa was 30°C and that of R. cirrhosa 20–30°C. The thermal optima and tolerances of growth and photosynthesis confirm the seasonal patterns of R. cirrhosa but not of C. nodosa. However, the sensitivity of C. nodosa to low salinities and temperatures may explain its absence from shallow coastal lagoons. Ruppia cirrhosa could be vulnerable to future climate change.

We propose a new Genetic Algorithm (GA) for solving the minimum span frequency assignment problem (MSFAP). The MSFAP is minimizing the range of the frequencies assigned to each transmitter in a region satisfying a number of constraints. The basic framework of the GA involves finding and ordering of the cells for use in a greedy (sequential) assignment process, and it also utilizes graph theoretic constraint to reduce search space. Because the performance of the GA heavily depends on the mutation rate, we use an adaptive mutation rate. And also a novel initialization method is utilized to improve the performance. Results are given which show that our GA produces optimal solutions to several practical problems,and the performance of our GA is far better than the existing GAs.

ACUTE POSTGANGLIONIC DYSAUTONOMIA WITH POLYNEUROPATHY Acute postganglionic dysautonomia (APD) was originally described by Young et aI9 in 1969 as pure pandysautonomia with complete recovery. However, several additional reports showed its variable clinical features in aspects of somatic involvements and recoveries. Electrophysiologically proven sensorimotor polyneuropathies were rarely combined with APD.2s6 We describe 2 patients with APD who simultaneously developed sensorimotor polyneuropathy.


The global context of this study is to improve the robustness of surface geophysical parameter retrieval models. Consequently, the adaptation of the existing retrieval models to radar measurement datasets is very important regarding the improvement of soil parameter retrieval procedures. In this context, the objective of this paper is to empirically adapt the Oh model based on the polarimetric RADARSAT-2 datasets acquired at different incidence angles, along with the simultaneous ground truth. The coefficients in the Oh model are adapted in order to decrease the deviation between Oh model predictions and SAR measurements. Improved agreements are found between the adapted Oh model and backscattering coefficients derived from multi-angular (ranged from 24° to 43°) SAR data. This indicates that the model adaptation could provide a way to improve the model behaviours and enhance the geophysical parameter retrieval.


The final performance of current and future instruments dedicated to exoplanet detection and characterization (such as SPHERE on the VLT, GPI on Gemini North or future instruments on the ELTs) is limited by intensity residuals in the scientific image plane, which originate in uncorrected optical aberrations. After correction of the atmospheric turbulence, the main contribution to these residuals comes from the quasi-static aberrations introduced upstream of the coronagraph which create long-lived speckles in the detector plane that can easily be mistaken for a planet. In order to reach very high contrast such as the ones required to image earth-like planets, these aberrations needs to be compensated for. We have recently proposed a dedicated focal-plane wave-font sensor called COFFEE (for COronagraphic Focal-plane wave-Front Estimation for Exoplanet detection), which consists in an extension of conventional phase diversity to a coronagraphic system: aberrations both upstream and downstream of the coronagraph are estimated using two coronagraphic focal-plane images, recorded from the scientific camera itself, without any differential aberration. Such a system has been successfully validated on the SPHERE instrument, where COFFEEs estimation has been used to compensate for the phase aberration upstream of the coronagraph, leading to a contrast optimization in the whole focal plane area controlled by the AO loop. If compensating for phase aberrations only was acceptable to reach levels of contrast of 10􀀀6, it will no longer be the case for instruments that aim at imaging earth-like planets. Such targets, which would be the ones of a planet-finder instrument integrated on an ELT, require a level of contrast better than 10􀀀9. To reach this level, neglecting amplitude aberrations (inhomogeneous intensity in the pupil, Fresnel propagation effect) is no longer possible. In this communication, we present an extension of COFFEE able to perform a simultaneous estimation of both phase and amplitude aberration from three focal plane images. After a theoretical presentation, we present a study of its performances. Notably, we analyze the contrast that can be achieved in a compensation process when this estimation method is combined with our non-linear dark hole method, demonstrating that the nanometric precision estimation that can be achieved with COFFEE allow one to reach very high contrast levels. It is worth mentioning that both estimation (COFFEE) and compensation (the nonlinear dark hole) methods are model based, and thus easily adaptable to a broad class of coronagraphic device. Lastly, we validate our complex field estimator on the LAM (Laboratoire dAstrophysique de Marseille) XAO test bench, described in this communication. We introduce calibrated phase and amplitude aberration in the entrance pupil plane. Then, we demonstrate the ability of our extended version of COFFEE to estimate both phase and amplitude aberration from three coronagraphic focal plane images that differs from a known aberration.


Abstract Vietnam's pulp and paper industry has contributed significantly to socio-economic growth but is also one of the industries with a very high risk of environmental pollution. Stems from the goal of economic growth coupled with environmental protection operations in Vietnam, this study examines the factors affecting the implementation of environmental management accounting (EMA) in manufacturing enterprises in Vietnam's pulp and paper industries. The data used in the study were collected through survey questionnaires in the form of face-to-face interviews or sent by e-mail or post to survey respondents at 290 manufacturing enterprises pulp and paper in provinces and cities of Vietnam. Survey subjects are managers (directors, deputy directors, chief accountants) and accountants who have knowledge of EMA in these enterprises. The survey results were obtained from 250 valid survey questionnaires used in this study. This study uses Cronbach's alpha analysis, exploratory factor analysis, and linear regression analysis using SPSS 20 statistical software. The results show that coercive pressure, normative pressure, awareness of the benefits of applying EMA, environmental strategy, managers' perception, and qualifications of accountants have a positive impact on EMA implementation. In which, coercive pressure has the strongest impact, and awareness of the benefits of applying EMA has the weakest impact on EMA implementation in these enterprises.


Nike is a term for minuscule fish that frequently appear in Gorontalo waters. This type of fish belongs to the amphidromous goby group. This study aims to describe the morphological alterations of Nike fish from the sea to the estuary area of Gorontalo waters based on molecular analysis and different melanophore pattern. The small size of this fish (larval stage and post-larva) cause difficulties in analysing morphometric and meristic aspects. Therefore, the melanophore pattern approach and molecular analysis using the COI gene were used to identify and study the fish species. Sampling was carried out from 5 to 11 October 2018 in Gorontalo Bay area and the mouth of Bone Bolango river. The study was carried out when this type of fish appeared in the research area. Samples of Nike fish were grouped based on differences in melanophore patterns in the body. It was found there were five different groups. The groups were coded N1, N2, N3, N4 and N5. The molecular analysis using the COI gene was used to identify the fish species. Genetic investigations showed that from five groups, there were two groups (N3 and N5) that had different melanophore patterns, but belong to the same species, Belobranchus segura. Morphological changes have occurred due to an increase in the melanophore patterns of Nike species when they migrate from the sea to the river.


Influence of environmental enrichment on behavioral of Galictis cuja, lesser grisson, kept in captivity at the zoo in the city of Piracicaba, SP.

Voltage Source Converter (VSC) based HVDC (VSC- HVDC) transmission technology as a kind of new dc transmission, is attracting more and more research. VSCs are susceptible to cable short-circuit fault and ground fault. This paper focuses on the transient characteristics of electrical quantities in a two terminal VSC-HVDC system after the occurrence of short-circuit fault and ground fault. Equivalent circuits and equations are given to calculate the voltage and over-current in cable. Simulations are undertaken in PSCAD to verify the calculation results, and different fault points and fault resistances are considered. Due to the behaviors of DC voltage and cable over-current in faulty cable and non-faulty cable after the ground fault, a DC cable protection principle was proposed to determine the faulty cable and to decide fault within or outside the protected area.

Ultrasonic guided waves have the ability to propagate long distances with minimal attenuation, which makes them particularly interesting in structural health monitoring (SHM) applications. Using the baseline subtraction approach, the signal from a defect-free structure is compared with the actual monitoring signal to detect and locate defects. There are many scientific publications on low-frequency guided waves for SHM purposes, and the interaction between guided wave fundamental modes and defects is also well documented. There is however a very limited number of studies on high order modes. High-frequency guided waves may enable the detection of smaller cracks related to conventional low-frequency guided wave SHM. The main difficulty at high frequency is the existence of several modes with different velocities. This study investigates the scattering of high order guided wave modes around a through-thickness hole with a view to developing a highly sensitive SHM method.

As the atmosphere warms more and more every day due to global warming, CO2 reduction is crucial in the current circumstances. To reduce this issue, we have come up with a solution where we can reduce it by calculating the levels of CO2 and converting it into useful resources which will be utilized efficiently. In this project, we have implemented the detection of CO2 levels present around us using MQ-135 sensor using Arduino. In this we get the levels of CO2 will be shown on an LCD screen that is connected to an Arduino board and the sensor. When the levels rise, it is a warning that we need to efficiently recycle or convert this harmful gas. Here, the idea was to use chemicals to turn CO2 into moisture.
