DETERMINATION OF A NEW PROMISING NATURAL ANTIFUNGAL PRODUCT AGAINST PENICILLIUM DIGITATUM

The present study deals with the fungal infections, a great amount of food losses occur worldwide. The infections caused by Penicillium digitatum, green mold agent in Citrus fruits, are just one of those losses. In this study, determining a novel environmentally-friendly antifungal product against green mold agent is aimed. Total 39 plant species, naturally growing in Kırklareli (Turkey) were scanned in terms of antifungal activity against P. digitatum. Digitalis viridiflora, Medicago lupulina and Sambucus ebulus, inhibited the micelle development of P. digitatum completely (100%), while Lythrum salicaria, Epilobium roseum and Prunella vulgaris inhibited the micelle development over 75%. D. viridiflora has showed the least MIC value (250 μg/ml) against P. digitatum. In SEM analysis, flattening, collapse and wrinkling effects of D. viridiflora on hyphae structure of P. digitatum were also observed during the present investigation. In the lemons treated with 8 mg/ml D. viridiflora aqueous extract, 73.99% regression in the lesion diameters has also been observed. As a result, in order to avoid green mold infection caused by P. digitatum occurring in lemon fruits, D. viridiflora can be used as a natural antifungal agent.
Hurricane Bonnie (1998): Maintaining Intensity during High Vertical Wind Shear and an Eyewall Replacement Cycle

Hurricane Bonnie (1998) was an unusually resilient hurricane that maintained a steady-state intensity while experiencing strong (12–16 m s−1) vertical wind shear and an eyewall replacement cycle. This remarkable behavior was examined using observations from flight-level data, microwave imagery, radar, and dropsondes over the 2-day period encompassing these events. Similar to other observed eyewall replacement cycles, Bonnie exhibited the development, strengthening, and dominance of a secondary eyewall while a primary eyewall decayed. However, Bonnie’s structure was highly asymmetric because of the large vertical wind shear, in contrast to the more symmetric structures observed in other hurricanes undergoing eyewall replacement cycles. It is hypothesized that the unusual nature of Bonnie’s evolution arose as a result of an increase in vertical wind shear from 2 to 12 m s−1 even as the storm intensified to a major hurricane in the presence of high ambient sea surface temperatures. These circumstances allowed for the development of outer rainbands with intense convection downshear, where the formation of the outer eyewall commenced. In addition, the circulation broadened considerably during this time. The secondary eyewall developed within a well-defined beta skirt in the radial velocity profile, consistent with an earlier theory. Despite the large ambient vertical wind shear, the outer eyewall steadily extended upshear, supported by 35% larger surface wind speed upshear than downshear. The larger radius of maximum winds during and after the eyewall replacement cycle might have aided Bonnie’s resiliency directly, but also increased the likelihood that diabatic heating would fall inside the radius of maximum winds.
A nonlinear switched control strategy for permanent magnet synchronous machines

A novel approach for controlling permanent magnet synchronous machines (PMSMs) based on switched systems theory is presented in this paper. The PMSM is generally fed by a three-phase voltage source inverter with six electronic switches whose control is responsible for orchestrating the machine shaft velocity towards a desired steady-state value. This assembly is modeled as a nonlinear switched system characterized by sinusoidal functions of the machine shaft displacement, whose properties are suitably explored in order to obtain the control design conditions. Our main goal is to design a state dependent switching function for this class of switched nonlinear systems to assure asymptotic stability and a maximum guaranteed decay rate for the closed-loop system. The design is based on a non-quadratic Lyapunov function and the stability conditions are expressed in the form of a generalized eigenvalue minimization problem. A simulation example is used to show the efficiency of the proposed control methodology as well as to discuss future work.
Squirrel Cage Induction Motor Design and the Effect of Specific Magnetic and Electrical Loading Coefficient

3-phase induction motors are widely used in industrial applications such as pumps, blowers, compressors, conveyors, etc. In addition, single-phase motors also have domestic use. For this reason, the design of the induction motor is of great importance. During the design, according to the parameters given as input, there are many situations that are contradictory to each other in order to achieve the goal. For example, if high efficiency is required, the motor size and the price will increase, and if lower price is required, other performance characteristics should be ignored. In the practical design of an induction motor, the designer has to comply with a number of constraints because of the large number of input variables. For this reason manual calculation becomes a very long and difficult process. To overcome this tiresome process, it is necessary to create a computer aided program or simulation model to determine the induction motor design parameters. In induction motor design, many parameters directly affect motor performance. Therefore, the selection of these parameters is of great importance. The C 0 coefficient, which takes place in the first steps of the design process, also has a great influence on the motor design. In this paper, a program for optimizing design of 3-phase induction motors written in MATLAB is presented. The structure of the program is modular and therefore can be modified for the various requirements of the induction motor design. C 0 constant (output coefficient), one of the design parameters, also varies with some other parameters. The most important ones are the specific electrical loading coefficient ( A 1 ) and the specific magnetic loading coefficient ( B av ), making dramatic effect on the output coefficient. The effect of the variation of the C 0 constant on the performance of the induction motor was investigated in the study. Stator inner and outer diameter, stack length, stator and rotor slot parameters, equivalent circuit parameters, losses and efficiency was obtained according to the change of B av and A 1 values. The obtained results are given and interpreted in tables and graphs.
Effects of Market Structure and Patient Choice on Hospital Quality for Planned Patients

We investigate the change in the effect of market structure on planned hospital quality for three high-volume treatments, using a quasi difference in differences approach based on the relaxation of patient constraints on hospital choice in England. We employ control functions to allow for timevarying endogeneity from unobserved patient characteristics. We find that the choice reforms reduced quality for hip and knee replacement but not for coronary bypass. This is likely due to hospitals making a larger loss on hip and knee replacements, since robustness checks rule out changes in length of stay, new competitorsâ€™ entry and hospital-level mortality as possible confounders.
Investigation of Antibacterial Activity of Crude Extracts from Marine Snails and Bivalves in the Southern Coast of Vietnam

The primary antibacterial activity of methanol and chloroform crude extracts from marine snails and bivalves was assessed by using the agar diffusion technique against four bacterial strains. Active methanol extracts were then characterized using TLC, SDS-PAGE and FTIR. Methanol extracts from 5 snail species and 8 extracts from 12 bivalve species possessed the ability to inhibit Bacillus subtilis . Methanol extracts from 3 snail species Tectus conus, Maninella alounia and Trochus maculatus inhibited Escheria coli and those from 4 snail species Cerithium chinatum, Maninella alounia, Tectus pyramis, Trochus maculatus and the bivalve species Pinna bicolor exhibited activity against Serratia marcescens . Chloroform extracts from 7 snail species and those from 7 bivalve species showed inhibition on Bacillus subtilis . Only chloroform extract from the bivalve Chama cf dunkeri was active on Salmonella typhimur and that from the snail Trochus maculatus and bivalve Lopha cristagali inhibited Escheria coli . TLC and FTIR analysis of active methanol extracts showed the presence of amino acids, peptides and proteins. SDS-PAGE of those extracts also revealed proteins with a molecular weight range between 10 and 28 kDa. The obtained results indicate the potential antimicrobial compounds that could be explored in snail and bivalve in Vietnam.
Women’s Role in the Accounting Profession: A Comparative Study between Italy and Romania

Historically, in most countries, the accounting profession has always been male-dominated. Liberal professions such as lawyers, engineers, architects and doctors share the common trait of conservatism. The accounting profession, which is also a liberal profession, is no exception. Starting from this premise, this work aims to provide, using a historical and institutional perspective, a picture of the past and current “journey” in the accountancy profession of women-chartered accountants and auditors in Italy and Romania. Drawing from the theoretical framework of gendered construction of the accounting profession, the paper points out issues affecting the presence, the degree of representativeness and the role (concerning the presence among the higher level of professional activities and governance positions) of women within the National Chartered Association and their continued under-representation in Italy and Romania. Findings contribute to providing insights useful to develop a future agenda and fill in the research gaps in this field.
Turbulence Variations in the Upper Troposphere in Tropical Cyclones from NOAA G-IV Flight-Level Vertical Acceleration Data

The NOAA G-IV aircraft routinely measures vertical aircraft acceleration from the inertial navigation system at 1 Hz. The data provide a measure of turbulence on a 250-m horizontal scale over a layer from 12.8- to 14.8-km elevation. Turbulence in this layer of tropical cyclones was largest by 35%–40% in the inner 200 km of radius and decreased monotonically outward to the 1000-km radius. Turbulence in major hurricanes exceeded that in weaker tropical cyclones. Turbulence data points were divided among three regions of the tropical cyclone: cirrus canopy; outside the cirrus canopy; and a transition zone between them. Without exception, turbulence was greater within the canopy and weaker outside the canopy. Nighttime turbulence exceeded daytime turbulence for all radii, especially within the cirrus canopy, implicating radiative forcing as a factor in turbulence generation. A case study of widespread turbulence in Hurricane Ivan (2004) showed that interactions between the hurricane outflow channel and westerlies to the north created a region of absolute vorticity of −6 × 10−5 s−1 in the upper troposphere. Outflow accelerated from the storm center into this inertially unstable region, and visible evidence for turbulence and transverse bands of cirrus appeared radially inward of the inertially unstable region. It is argued that both cloud-radiative forcing and the development of inertial instability within a narrow outflow layer were responsible for the turbulence. In contrast, a second case study (Isabel 2003) displayed strong near-core turbulence in the presence of large positive absolute vorticity and no local inertial instability. Peak turbulence occurred 100 km downwind of the eyewall convection.
An improved method to predict the Wulff shape : An example for Li 2

TheWulff construction based on surface energy calculations is an effective tool to understand and predict the shape of nanoparticles. Previous surface energy calculation faces the challenge to precisely deal with the dipole electric field in a slab. Here we propose a method that by fitting the calculated surface energies with no dipole electric field through multivariate linear regression, the separate contributions to the surface energy from the cations coordination loss terms on the surface can be obtained. The fitted results can further be used to estimate the surface energies of slabs with dipole electric field directly and accurately. Using this method, the Wulff shapes of three phases of Li2CoSiO4, a kind of materials with great potential for oxygen evolution reaction (OER) electrocatalysts, are precisely constructed. 2017 Elsevier B.V.

Impact of Integrative Management Strategies on the Reproduction of Root Knot Nematode, Meloidogyne incognita

Present investigation was planned to check the impact of bio (Cure, Azadirachtin) and synthetic (Cartap, Virtako) chemicals individually and concomitantly with fertilizers on the development of root knot nematode, Meloidogyne incognita and the growth of tomato ( Solanum lycopersicum ) plants. Tomato seedlings were transplanted in sterilized soil amended with Cartap, Virtako, Cure and Azadirachtin at their recommended doses and inoculated with 500 freshly hatched juveniles (J 2s ) of M. incognita . Data were recorded after 7, 14, 21 and 28 days to check the invasion and development stages. All the treatments significantly reduced invasion and subsequent development of M. incognita in roots. Different application methods regarding protective and curative were used to test the efficacy of Cartap, Virtako, Cure and Azadirachtin. Results revealed that Protective application of bio and synthetic chemicals was more effective at nematode suppression rather than being curative. Then the impact of bio and synthetic chemicals were tested in combination with NPK on nematode reproduction. Following treatments i.e. Virtako + NPK, Cartap + NPK, Cure + NPK, Azadirachtin + NPK, control (N) and control (H) with ten replications were applied in pots containing tomato seedlings. Inoculation of 2000 freshly hatched J 2s of M. incognita was done. Results revealed that combined effect was more pronounced in reducing nematode reproduction and improving plant growth. Maximum number of J 2s was recorded in nematode control (1241.0) while a dynamic decline was observed in Cartap+NPK, Virtako+NPK, Cure+NPK and Azadirachtin+NPK (144.4, 162.2, 198.1, 216.6) respectively. Combined application of selected chemicals with fertilizers not only reduced nematode reproduction but also improved plant growth. So, the integrated use of chemicals with fertilizers could be a successful tool in management strategies of root knot nematode.
Marital Sanctification and Spiritual Intimacy Predicting Married Couples’ Observed Intimacy Skills across the Transition to Parenthood

This study examined the extent to which 164 married heterosexuals’ reports of the sanctification of marriage and spiritual intimacy during pregnancy predicted the trajectory of the couples’ observed intimacy skills during late pregnancy and when their first child was 3, 6, and 12 months old. At each time point, couples were videotaped in their homes for 10 min discussing their fears and vulnerabilities about becoming and being a new parent. Separate teams of three coders rated the four interactions and each spouse’s intimacy skills, including disclosure of feelings of vulnerability about becoming or being a new parent, and supportive comments and positive non-verbal responses to each other. Using a multi-level dyadic discrepancy approach to growth curve modeling, both husbands’ and wives’ observed intimacy skills displayed a curvilinear trajectory over the first year of parenthood, with wives consistently displaying more emotional intimacy skills than husbands. Consistent with hypotheses, higher endorsement of the sanctification of marriage and spiritual intimacy between spouses at home predicted higher observed intimacy skills across time. No variation in these associations emerged due to parent gender. Thus, this longitudinal study identifies two specific spiritual processes within marriages that may motivate spouses to share their vulnerabilities and provide one another with valuable emotional support in coping with the transition to parenthood.
Techno-Economic Assessment of New Solvents for CCS

Gas fired power plants will likely remain part of the future energy mix and chemical solvent based post-combustion CO2 capture offers a way of decarbonizing this type of electricity generation. In this study, we present a techno-economic assessment of five solvents, including two new proprietary solvents, applied in an archetypal capture plant treating a flue gas stream with 4mol% CO2. The solvents’ performance is compared using a reduced order modeling technique with partial optimization of process parameters and parametric equipment cost estimation. The CO2 loading in the lean solvent returned to the absorber is varied in each case to find the lowest total annualised cost for each solvent. The estimated total annualised costs range from $100 per ton of CO2 down to $76 per ton of CO2.
Ventilator-derived dynamic respiratory system compliance

Measurement of dynamic lung compliance during breathing requires measurement of esophageal pressure, whereas static respiratory system compliance (Crs) method requires several airway occlusions. Despite their precision these compliance methods are cumbersome and not suitable for evaluation of pulmonary system in intensive care. The current ventilators display dynamic Crs, which, however, is seldom utilized in clinical practice. We studied the feasibility of ventilator-derived dynamic Crs measurement in pulmonary evaluation after congenital cardiac surgery in children. In 50 children static Crs was measured by double-occlusion technique, and compared with simultaneous ventilator-derived dynamic Crs values. The early postoperative dynamic and static Crs showed a correlation (r= 0.57, p < 0.0001), but static Crs was 48% higher than dynamic (p < 0.0001). Dynamic Crs measurement showed no correlation with radiographic lung edema findings, whereas the static Crs showed a negative correlation with radiographic lung edema scoring (r=−0.50, p= 0.0002). Thus ventilator-derived dynamic Crs seems less reliable in postoperative pulmonary evaluation than static Crs.
reading frame structure analysis as a novel genotyping tool for hepatitis E virus and the subsequent discovery of an inter-genotype recombinant

Received 5 December 2008 Accepted 17 February 2009 Accurate viral genotyping is important. Here I investigate genotypes in hepatitis E virus (HEV) and find that the open reading frame (ORF) structure (the lengths of three ORFs and the overlapping relationships among the ORFs) can be a good criterion for genotyping HEV. An inter-genotype recombinant (GenBank accession no. DQ450072) was revealed by analysing the ORF structure and confirmed by phylogenetic analyses. This discovery of the inter-genotype recombinant indicates that genotyping in HEV should be based on full-length sequences. The Mexican strain which is currently classified as a genotype 2 strain also exhibited the mosaic sequence pattern, although without statistical support.
Lignin as a Natural Carrier for the Efficient Delivery of Bioactive Compounds: From Waste to Health

Lignin is a fascinating aromatic biopolymer with high valorization potentiality. Besides its extensive value in the biorefinery context, as a renewable source of aromatics lignin is currently under evaluation for its huge potential in biomedical applications. Besides the specific antioxidant and antimicrobial activities of lignin, that depend on its source and isolation procedure, remarkable progress has been made, over the last five years, in the isolation, functionalization and modification of lignin and lignin-derived compounds to use as carriers for biologically active substances. The aim of this review is to summarize the current state of the art in the field of lignin-based carrier systems, highlighting the most important results. Furthermore, the possibilities and constraints related to the physico–chemical properties of the lignin source will be reviewed herein as well as the modifications and processing required to make lignin suitable for the loading and release of active compounds.
Resource Management and Optimization Method of Music Audio-Visual Archives under the Background of Big Data

With the development of music and video, music and video management has been in a relatively backward state. This study uses the logistic regression algorithm based on sigmoid functions to analyze and process the music audio-visual library of a music software and establishes the logistic regression dynamic model, which provides a scientific research method for this complex system. The LPC characteristic coefficient is extracted, and then the logistic regression model of music audio-visual archives resources is established. After completing the model, this study obtains the logistic regression model through a series of experiments, which effectively optimizes the management of music audio-visual archives. The specific experimental conclusions are as follows: through genre classification and emotion classification, users can search more music audio-visual archives resources. The comparison shows that the recommendation effect after filtering by the logistic regression model is better than that of the nonstandard collaborative filtering recommendation system. Finally, after practical applications, it is concluded that the model based on the logistic regression algorithm has made a good optimization conclusion for the resource management of music audio-visual archives.
Physics-based analysis of the hydrodynamic stress in a fluid-particle system

The paper begins by showing how standard results on the average hydrodynamic stress in a uniform fluid-particle system follow from a direct, elementary application of Cauchy’s stress principle. The same principle applied to the angular momentum balance proves the emergence, at the mesoscale, of an antisymmetric component of the volume-averaged hydrodynamic stress irrespective of the particle Reynolds number. Several arguments are presented to show the physical origin of this result and to explain how the averaging process causes its appearance at the mesoscale in spite of the symmetry of the microscale stress. Examples are given for zero and finite Reynolds number, and for potential flow. For this last case, the antisymmetric stress component vanishes, but the Cauchy principle proves nevertheless useful to derive in a straightforward way known results and to clarify their physical nature.
Angle-resolved photoemission and quasiparticle calculation of ZnO: The need for d band shift in oxide semiconductors

ZnO is a prototypical semiconductor with occupied d 10 bands that interact with the anion p states and is thus challenging for electronic structure theories. Within the context of these theories, incomplete cancellation of the self-interaction energy results in a Zn d band that is too high in energy, resulting in upwards repulsion of the valence band maximum (VBM) states, and an unphysical reduction of the band gap. Methods such as GW should significantly reduce the self-interaction error, and in order to evaluate such calculations, we measured high-resolutionandresonantangle-resolvedphotoemissionspectroscopy(ARPES)andcomparedthesetoseveral electronic structure calculations. We find that, in a standard GW calculation, the d bands remain too high in energy by more than 1 eV irrespective of the Hamiltonian used for generating the input wave functions, causing a slight underestimation of the band gap due to the p-d repulsion. We show that a good agreement with the ARPES data over the full valence band spectrum is obtained, when the Zn-d band energy is shifted down by applying an on-site potential Vd for Zn-d states during the GW calculations to match the measured d band position. The magnitude of the GW quasiparticle energy shift relative to the initial density functional calculation is of importance for the prediction of charged defect formation energies, band-offsets, and ionization potentials.
