The sensitivity of runoff generation to spatial snowpack uniformity in an alpine watershed: Green Lakes Valley, Niwot Ridge Long‐Term Ecological Research station

Seasonal water storage in high‐elevation alpine catchments are critical sources of water for mountainous regions like the western U.S. The spatial distribution of snow in these topographically complex catchments is primarily governed by orography, solar radiation, and wind redistribution. While the effect of solar shading is relatively consistent from year‐to‐year, the redistribution of snow due to wind is more variable – capable of producing snowpacks that have varying degrees of uniformity across these hydrologically‐important catchments. A reasonable hypothesis is that a warmer climate will cause snowfall to become more dense (i.e. wetter and heavier), possibly leading to less wind redistribution and thus produce a more uniformly distributed snowpack across the landscape. In this study, we investigate the role of increasingly uniform spatial snowpack distributions on streamflow generation in the Green Lakes Valley Niwot Ridge Long Term Ecological Research station, within the headwaters of the Boulder Creek watershed in Colorado. A set of idealized hydrologic simulation experiments driven by reconstructed snowpacks spanning 2001–2014 show that more a more uniform spatial snowpack distribution leads to an earlier melt‐out of 31 days on average and tends to produce less total streamflow, with maximum decreases as large as 7.5%. Isolating the role of snowpack heterogeneity from melt‐season precipitation, we find that snowpack uniformity reduces total streamflow by as much as 13.2%. Reductions in streamflow are largely explained by greater exposure to solar radiation in the uniformly distributed case relative to a more heterogeneous snowpack, with this exposure driving shifts towards earlier snowmelt and changes in soil water storage. Overall, we find that the runoff efficiency from shallower snowpacks is more sensitive to the effects of uniformity than deeper snowpacks, which has potential implications for a warming climate where shallower snowpacks and enhanced sensitivities may be present.
Preliminary evaluation of phytochemicals in Iresine herbistii ethanol leaf extract using gas chromatography-mass spectrometry analysis

Objective: This research is to identify the possible phytocompound in Iresine herbistii leaves for the health benefit of man and animals. Plants are the major sources of drugs. Methods: Gas Chromatography Mass Spectrometry [GC-MS] analysis was used for screening the secondary metabolites in the leaves of I. herbistii as a preliminary study. The extract was prepared using soxhlet extraction method with ethanol as solvent. It was concentrated at 35 o C in hot air oven. Results: The gas chromatogram showed the presence of ten possible phytocompounds. The molecular mass of the phytocompounds were established based on the molecular ion in the mass spectra. The suggested compounds are Furan-2-carboxylic acid with peak area percentage (PA%) of 0.80 and retention time (RT) 3.822; 2-Ethyl-2-hexen-1-al with PA% of 0.58 and RT 3.925; Diethylene glycol monomethyl ether with PA% of 1.60 and RT 6.630; Methyl 14-methylpentadecanoate with PA% of 6.80 and RT 15.890; Hexadecanoic acid also known as Palmitic acid with PA% of 10.02 and RT 16.534; Methyl linolelaidate with PA% of 12.12 and RT 18.249; Linolenic acid, methyl ester with PA% of 30.36 and RT 18.367; 2,5-dihydroxycyclohexa-2,5-diene-1,4-dione with PA% of 21.07 and RT 18.644; 5-chloropyridin-2-ol with PA% of 14.23 and RT 19.370; 17-Carboxyoctadeca-2,4-dien-1-ylium with PA% of 2.42 and RT 24.782. Conclusions: The bioactivity studies showed that I. herbstii leaves is an acidifier, arachidonic acid-inhibitor, 5-alpha-reductase-inhibitor, allergenic, alexiteric, algogenic (pain-causing) and oligosaccharide provider. It is therefore necessary that further isolation and synthesis of the bioactivities from this plant be done for proper utilization as medicinal plant.
THE INFLUENCE OF PROFESSIONAL COMPETENCY OF SERVICE OFFICERS ON SERVICE QUALITY DIMENSIONS IN PUBLIC SERVICES

One of the benchmarks for the implementation of good governance can be seen from the implementation of quality and satisfaction-oriented public services. Public satisfaction is greatly influenced by how or the behavior of officers in providing services. Therefore, the existence of service officers will determine the extent to which public organizations can achieve their goals in meeting public expectations. The primary data includes respondents' responses to research variables which include professional competence, service quality (tangible dimensions, reliability dimensions, responsiveness dimensions, assurance dimensions, empathy dimensions), and public satisfaction. This research was conducted to test the hypothesis to justify or strengthen the hypothesis in the hope that in the end, it can strengthen the theory that is used as a foothold. In general, this study can be concluded that all dimensions of service quality (tangible, reliable, responsive
Does total antioxidant capacity play a central role in postharvest deterioration of 'Sweetheart' sweet cherry fruit?

'Sweetheart' cherries (Prunus avium L.) have sweet flavour, bright red colour and a distinctive heart shape which contributes to their wide commercial acceptance. They display also comparatively high firmness and long shelf-life potential. Enzyme-catalysed disassembly of cell walls has been generally targeted as the main factor accounting for ripening-related changes in fruit firmness and overall texture, but the biochemical mechanisms involved in this process appear to include additional factors such as oxidative scission of cell wall polysaccharides. In this study, 'Sweetheart' fruit were hand-collected at commercial maturity, and kept at 0 oC for 15 or 30 days plus 3 days at 20 oC to mimic their retail period. Firmness, weight loss and juiciness, together with the incidence of decay and stem browning, were chosen as indicators of commercial quality of fruit. Cell wall materials were extracted and fractionated, related enzyme activities were assessed, and ascorbic acid content as well as radical scavenging activity (RSA) were also determined. Fruit displaying higher RSA showed higher values for firmness and lower weight loss, decay and stem browning incidence. Higher firmness levels were associated to higher RSA and to yields of the cell wall fractions enriched in convalently-bound pectins and hemicelluloses. β-galactosidase, pectinmethylesterase and endo-1,4-β-D-glucanase activities correlated inversely to firmness, while pectate lyase activity appeared to be relevant for solubilisation of cell wall materials and was inversely related to ascorbic acid content.
Measurement of temperature in the laser heated diamond anvil cell: comparison between reflective and refractive optics

ABSTRACT In this article we present a direct comparison between reflective (Schwarzschild mirrors) and refractive (achromatic doublets) optics commonly used in spectroradiometric temperature measurements in laser heated diamond anvil cells. Emission spectra are fitted with the Planck's law and are further analysed with the two-colour technique; theoretical simulations are used to compare the temperature measurement accuracy of the two optical systems. The first result obtained is that achromatic doublets with large numerical aperture () produce extensive accuracy errors in the full T range (1500–3000 K). When reduced apertures () are used a good agreement is found with measurements from reflective optics up to 2600 K while systematic differences (around 200 K) appear at higher temperatures. However, these temperature differences cannot explain the discrepancies between the iron melting curves obtained in the past years using laser heated diamond anvil cells.
Etude de la régulation du canal CFTR impliqué dans la mucoviscidose par un analogue de la GnRHet le Mg2

La mucoviscidose est la maladie hereditaire autosomique recessive, rare, letale, la plus frequente dans la population caucasienne. Cette maladie est causee par des mutations du gene CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) codant la proteine CFTR. Cette proteine est principalement un canal chlorure (Cl-) AMPc-dependant localise dans la membrane apicale des cellules epitheliales. La mutation F508del entraine un defaut de maturation de la proteine qui est retenue dans le reticulum endoplasmique avant d’etre degradee. Cependant, une faible quantite de proteines malformees echappe a ce systeme de controle et parvient a la membrane plasmique.Des travaux de notre equipe ont montre une augmentation des efflux ioniques dependants du CFTR dans des lignees cellulaires epitheliales bronchiques (CFBE41o-), exprimant le CFTR sauvage ou le CFTR mute F508del, apres un traitement par une hormone: la gonadoliberine (GnRH, Gonadotropin releasing hormone, 1h, 10-9M). Cette augmentation est vraisemblablement due a un nombre plus important de canaux CFTR a la membrane plasmique.L’objectif de cette these a ete de tester un analogue de la GnRH comme modulateur de l’exportation membranaire et/ou de l’activite canal du CFTR mute, sur des cultures primaires de cellules epitheliales nasales humaines homozygotes pour la mutation F508del. Dans un premier temps, nous avons verifie la presence du recepteur a la GnRH (R-GnRH) dans notre modele cellulaire. Puis, nous avons etudie l’effet de l’analogue sur la fonction du CFTR par des techniques d’electrophysiologie. Nous avons observe une augmentation des efflux d’ions Cl- medies par le canal CFTR apres un traitement a l’analogue (2h, 10-12M). Enfin, une etude proteomique nous a permis d’identifier des proteines differentiellement exprimees apres traitement. Certaines proteines mises en evidence pourraient appartenir a des voies de signalisation intracellulaires ayant un role dans la regulation de la proteine CFTR et etre des cibles therapeutiques.Par ailleurs, le canal CFTR est regule par le Mg2+ intracellulaire ([Mg2+]i). Le canal TRPM7 est le principal regulateur du [Mg2+]i. La [Mg2+]i a ete mesuree et l’expression de TRPM7 verifiee dans des cellules Hela transfectees avec le CFTR sauvage (wt) ou mutes (G551D et F508del). Nous avons etudie la localisation, la fonction et la regulation de TRPM7 dans nos modeles cellulaires avant de rechercher un possible lien fonctionnel entre le CFTR et TRPM7. Dans les modeles CF, l’expression, la fonction et la localisation du canal TRPM7 sont alterees. Il existerait un lien fonctionnel entre TRPM7 et le CFTR par l’intermediaire de la diminution du [Mg2+]i impliquant TRPM7 dans la physiopathologie de la mucoviscidose.
SEASONAL CHANGE AS BASIS FOR PREDICTION OF PLASMODIUM SPECIES IN EPIDEMIC REGIONS OF VISAKHAPATNAM DISTRICT, ANDHRA PRADESH.

Malaria epidemics due to Plasmodium species are reported frequently in the Andhra Pradesh, Visakhapatnam highlands with high case fatality rates. There have been formal attempts to predict epidemics by the use of climatic variables that are predictors of transmission potential. However, little consensus has emerged about the relative importance and predictive value of different factors. Understanding the reasons for variation is crucial to determining specific and important indicators for epidemic prediction. The impact of temperature on the duration of a mosquito’s life cycle and the sporogonic phase of the parasite could explain the inconsistent findings. To improve reliability and general liability within similar climatic conditions, we grouped the districts into two climatic zones, hot and cold. In cold districts, rainfall was associated with a delayed increase in malaria cases, while the association in the hot districts occurred at relatively shorter lags. The interaction between climatic factors and their biological influence on mosquito and parasite life cycle is a key factor in the association between weather and malaria. These factors should be considered in the development of malaria early warning system.
Determining the adsorption and desorption behavior of thiabendazole fungicide for five different agricultural soils

Thiabendazole 2-(4'-thiazolyl)benzimidazole (TBZ) is a Benzimidazole fungicide. In the present study adsorption and desorption of TBZ was investigated through batch equilibrium method involving UV-Visible spectrophotometer and High-performance liquid chromatography. Linear and Freundlich coefficients and kinetics of TBZ was studied in different agricultural soils of Pakistan. 9. 8µgml -1 and 12. 09µgml -1 were highest values of K d ads and K d des respectively. K f ads values ranged from 6.6 to 8µgml -1 whereas values of K f des followed the range of 1. 5µgml -1 to 9. 8µgml -1 . Most of the samples depict negative hysteresis as their 1/n des was more than 1/n ads. Gibbs or free energy change (∆G) and hysteresis vividly proved physical and reversible adsorption process. The values of K om and K oc were indicated medium mobility group of TBZ in selected soils. However all kinetic values varied significantly from sample to sample depending on their physicochemical parameters.
Opportunistic experiments to constrain aerosol effective radiative forcing

Aerosol–cloud interactions (ACIs) are considered to be the most uncertain driver of present-day radiative forcing due to human activities. The nonlinearity of cloud-state changes to aerosol perturbations make it challenging to attribute causality in observed relationships of aerosol radiative forcing. Using correlations to infer causality can be challenging when meteorological variability also drives both aerosol and cloud changes independently. Natural and anthropogenic aerosol perturbations from well-defined sources provide “opportunistic experiments” (also known as natural experiments) to investigate ACI in cases where causality may be more confidently inferred. These perturbations cover a wide range of locations and spatiotemporal scales, including point sources such as volcanic eruptions or industrial sources, plumes from biomass burning or forest fires, and tracks from individual ships or shipping corridors. We review the different experimental conditions and conduct a synthesis of the available satellite datasets and field campaigns to place these opportunistic experiments on a common footing, facilitating new insights and a clearer understanding of key uncertainties in aerosol radiative forcing. Cloud albedo perturbations are strongly sensitive to background meteorological conditions. Strong liquid water path increases due to aerosol perturbations are largely ruled out by averaging across experiments. Opportunistic experiments have significantly improved process-level understanding of ACI, but it remains unclear how reliably the relationships found can be scaled to the global level, thus demonstrating a need for deeper investigation in order to improve assessments of aerosol radiative forcing and climate change.

iv with more accurate dynamics. An analysis of the different switching loss modes in class-DE resonant converters with frequency control and fixed dead time is conducted, and a feasible operating region for a given upper-loss bound is defined. Finally, a study of the figures of merit of the best-in-class switching devices and magnetic materials for high-frequency offline converters is presented, with an investigation of GaN devices reverse conduction characteristics and their corresponding losses in the different implementations. Through the application of the research described in this work, high-power density resonant converters with frequencies in the range of 1-2 MHz can be implemented with robust control and high power factor and efficiency.
Erection of duct-like graphitic carbon nitride with enhanced photocatalytic activity for ACB photodegradation

Novel duct graphitic carbon nitride (DCN) was successfully prepared using the temperature control method in a quartz tube furnace from commercially available melamine and evaluated against the photo-degradation of latent organic pollutants, acarbose (ACB). These prepared materials were characterized by UV–Vis spectroscopy, Fourier transform infrared spectra, x-ray photoelectron spectroscopy, x-ray diffraction, transmission electron microscopy and scanning electron microscopy. The characterization results indicated that the synthesized material was in the form of a duct-like structure and has greater adsorption capacity and photocatalytic ability as compared to traditionally synthesized graphitic carbon nitride materials. The DCN split theACB completely into many intermediates, which were depicted in the HPLC-MS spectrum for knowing the acarbose photo-degrdation pathway. The duct-like morphology of graphitic carbon nitride has improved properties, such as increasing the surface area and decelerating the e−/h+ recombination, which increase the light absorbance ability with enhanced photoactivity.

Dynamic Anion-Adaptive Poly(ionic liquid) Films via Surface-Initiated Ring-Opening Metathesis Polymerization

We report the surface-initiated ring-opening metathesis polymerization (SI-ROMP) of ionic liquid-tethered monomers to grow poly(ionic liquid) (PIL) films on gold and silicon substrates. The kinetics of film growth are rapid, with profilometric thicknesses approaching 600 nm within 15 min of polymerization in a 0.1 M monomer solution and substantial film growth observed at monomer concentrations as low as 0.02 M. The ionic liquid (IL) monomer consists of the cation 3-[(bicyclo[2.2.1]hept-5-en-2-yl)methyl]-1,2-dimethylimidazol-3-ium (N1-dMIm+) with the hexafluorophosphate (PF6–) anion. SI-ROMP of the IL monomer results in a surface-tethered poly(3-[(bicyclo[2.2.1]hept-5-en-2-yl)methyl]-1,2-dimethylimidazol-3-ium hexafluorophosphate) (p[N1-dMIm][PF6]) film whose PF6– anion can be easily interchanged to tune the film properties. The p[N1-dMIm][PF6] films were shown to be adaptive to their anionic environment with the extent of anion exchange characterized by reflectance-absorption infrared spectroscopy and ut.

A relação entre a evidenciação contábil e as características dos clubes de futebol que atuam no campeonato brasileiro da série A

This research aims to analyze the relationship between the disclosure of accounting information and the characteristics of the soccer clubs that act in the Brazilian Championship Series A, as determined in the NBC ITG 2003. Based on the theory of disclosure based on the judgment, it was expected that the characteristics of the soccer clubs may explain the heterogeneous level of evidence of the accounting information of these clubs. The survey has as a sample the 20 soccer clubs that participated in the Brazilian Championship of 2018. The analysis period understood from 2013 to 2017. As a methodology, multiple linear regression with panel data models was employed. The results obtained showed that the variables present in the model explain 56% of the evidences practiced by the clubs. In addition, variables, Active Size (TA), General Indebtedness (EG) and Number of Partners Supporters (QST) showed statistically significant relationship with the dependent variable.
Education Policy: comparing EU developments and national policies

In the field of education, European cooperation goes back a long way (Hingel, 2001; Corbett, 2005; Pépin, 2006 and 2007; Walkenhorst, 2008; Ertl, 2003 and 2006; Lawn and Grek, 2012). However, with the launch of the Lisbon Strategy, education and training gained new momentum. Under this strategy, the ‘Education and Training 2010’ (ET, 2010) work programme established the first comprehensive framework for European cooperation in the field of education. As a result, the Open Method of Coordination (OMC) was introduced in education and training.
Ultralight and Binder‐Free All‐Solid‐State Flexible Supercapacitors for Powering Wearable Strain Sensors

Flexible energy storage devices play a pivotal role in realizing the full potential of flexible electronics. This work presents high‐performance, all‐solid‐state, flexible supercapacitors by employing an innovative multilevel porous graphite foam (MPG). MPGs exhibit superior properties, such as large specific surface area, high electric conductivity, low mass density, high loading efficiency of pseudocapacitive materials, and controlled corrugations for accommodating mechanical strains. When loaded with pseudocapacitive manganese oxide (Mn3O4), the MPG/Mn3O4 (MPGM) composites achieve a specific capacitance of 538 F g−1 (1 mV s−1) and 260 F g−1 (1 mV s−1) based on the mass of pure Mn3O4 and entire electrode composite, respectively. Both are among the best of Mn3O4‐based supercapacitors. The MPGM is mechanically robust and can go through 1000 mechanical bending cycles with only 1.5% change in electric resistance. When integrated as all‐solid‐state symmetric supercapacitors, they offer a full cell specific capacitance as high as 53 F g−1 based on the entire electrode and retain 80% of capacitance after 1000 continuous mechanical bending cycles. Furthermore, the all‐solid‐state flexible supercapacitors are incorporated with strain sensors into self‐powered flexible devices for detection of both coarse and fine motions on human skins, i.e., those from finger bending and heart beating.
