Can Economic Moats Provide Investors With a Competitive Advantage

This thesis examines the relationship between competitive advantage and stock performance. Using Morningstar’s economic moat rating classifications, this paper contributes to the competitive advantage literature by providing an empirical assessment of whether wide moat stocks, or companies deemed to have sustainable competitive advantages, made for superior investments compared to non-wide moat stocks over a ten-year time-frame from 2008 to 2017. Additionally, this paper accounts for a previously under-studied topic within the economic moat literature by specifically analyzing three sectors and nine industries. The results indicate that wide moat stocks surprisingly may not make for a superior stock investment, as the wide moat observations in the selected sample were found to have a negative relationship with average annual returns (coefficient = -0.05) that was statistically significant at the 5% level. Companies with no economic moat, meanwhile, were found to have a positive relationship with average annual returns (coefficient = 0.02). Taken together, these results indicate that investment research firms such as Morningstar may place excessive weight on wide moat status and thus undervalue seemingly less attractive companies that have the potential to offer far higher returns.
Effects of shore height, wave exposure and geographical distance on thermal niche width of intertidal fauna

Environmental temperature is a controlling factor in ecology and is influenced by global climate change. Upper/lower thermal limits for 10 species of sessile/sedentary invertebrates were established on a single rocky shore. Two species with different reproductive strategies (Littorina litto- rea, Nucella lapillus) from 3 Scottish and 3 Irish shores were investigated to test effects of small scale (<10 km) or larger scale (ca. 500 km) distances, and shore height on upper lethal temperature. At 3 sheltered and 3 exposed shores in Ireland, thermal responses of N. lapillus from the middle of their vertical distribution were compared. Amongst the 10 species from a single shore, thermal niche width rose asymptotically with maximum height of distribution on the shore and maximum emersion time. Median upper lethal temperature and median lower lethal temperature were closely correlated. For 8 species on the middle and upper shore, there were significant linear relationships between shore height and the variables upper lethal temperature, lower lethal temperature and thermal niche width. L. littorea upper lethal temperature was found not to vary with shore height, varied little over small geographical distances, but was significantly higher in Ireland than in Scotland. N. lapillus upper lethal temperature was higher in animals collected from the upper limit of distribution on the shore than in dogwhelks from the lower limit of distribution, was higher in animals taken from sheltered shores than from exposed shores and showed significant local differences. Upper lethal temperature was higher in Scottish than Irish dogwhelks.
Poetry and the Scope of Metaphor: Toward a Cognitive Theory of Literature

The question I raise in this paper is, 'In what ways can cognitive theory as it has been developed in recent years contribute toward a more adequate theory of literature? ' To answer this question, I look at Emily Dickinson’s poem, 'My Cocoon Tightens,' to show how the general mapping skills that constitute the cognitive ability to create and interpret metaphor can provide a more coherent theory than the intuitive and ad hoc approaches of traditional criticism. I then look at another Dickinson poem, 'My Life had stood - a Loaded Gun,' to show how a cognitive metaphor approach can illuminate the insights, and the limitations, of traditional literary criticism. Finally, I show how the application of cognitive poetics can identify and evaluate literary style by discussing a poem generally believed to be by Dickinson but which proved to be a forgery, and end by comparing cognitive poetics to other cognitive approaches.

Journal of Applied Chemistry Evaluation of total phenolic content and antioxidant activity of Nelumbo nucifera seed from north of Iran

A b s t r a c t In this study antioxidant properties and total phenolic content of the extracts of Nelumbo nucifera seeds were examined. The extracts were prepared using the solvents water, methanol, water : methanol (1:1), ethyl acetate, acetone and chloroform. Two experimental methods including DPPH (1,1-Diphenyl-2-picryl-hydrazyl) radical scavenging activity and total antioxidant capacity were used for characterization of antioxidant activity of the extracts. The six extracts showed varying degrees of efficacy in each assay in a dose-dependent manner. The acetone extract with the highest amount of total phenolic content (20.12 ± 0.02 g GAE/100 g dried extract), was the most potent antioxidant in both assays used. The LSA exhibited strong free radical scavenging activity as evidenced by the low EC50 values in DPPH assay (4.28 μg/ml) and in total antioxidant assay by maximum activity (25% of ascorbic acid). On the basis of the results, the acetone extract of Nelumbo nucifera seeds were found to serve as a potential source of natural antioxidants.
A prospective study on clinical outcome of complicated external hernias

Background: External hernias are relatively simple diseases in themselves to treat; however, complications developing in them, such as irreducibility, obstruction and strangulation, may present as a life-threatening one. Objective: To study the characteristics of these patients and identification of risk factors that may predict development of these complications would help place the patient in a high-risk group and subsequent intervention. Methods : It is a prospective descriptive study in patients presenting to Surgery Department of BPKIHS, Dharan, Nepal with a diagnosis of complicated external hernias from December 2009 to July 2011. Results : There were a total of 63 patients including 53 males (84.1%) and 10 females (15.8%). The average age of the patients was 49.23+21.4 years (range 10 days-85 years). The average duration of hernia was 6.36+6.57 years (range 5 hours -30 years). The median duration of complications was 2 days (range 5 hours-15 years). There were 7 mortalities (11.11%). The morbidity rate was 33.33% (21 cases). Risk factors identified for mortality were age >65 years (p=0.004), inguinal hernias (p<0.001), presence of co-morbid diseases (p<0.001), presence of strangulation (p=0.007) and bowel resection (p<0.001); and for morbidities were type of hernia (p<0.001), presence of co-morbid diseases (p=0.013), and bowel resection (p=0.002). Conclusion : Elderly males with co-morbid diseases with inguinal hernia and with strangulation and needing bowel resection are most likely to die from more complications. Such patients when seen in the outpatient department should be given priority admission and taken up for early elective surgery.

Insight into Rotational Effects on a Horizontal Axis Wind Turbine NREL Phase ii Using CFD simulation and inverse BEM

The present work aims to study the aerodynamic characteristics of the NREL phase II rotor (generated only with S809 profile along the span for an untwisted case) that is a horizontal axis downwind wind turbine rotor and which is assumed to stand isolated in the space. The three-dimensional steady-incompressible flow Reynolds Averaged Navier-Stokes equations are solved by using the commercial CFD package ANSYS FLUENT and, the turbulence closure model k-ω with shear stress transport correction was adopted for all computations. The computations were done for wind speed of 7.2, 10.56, 12.85, 16.3, and 9.18 m.s -1 . Results of pressure and torque for considered wind turbine rotor have been directly compared to the available experimental data. The comparisons show that CFD results along with the turbulence model can predict the span-wise loading of the wind turbine rotor with reasonable agreement. Secondly, A comparison of lift and drag coefficients was made between the results obtained using the inverse algorithm BEM based on the calculated pressure distributions and the experimental test data. The result show that the general trend is similar for all sections of the scale, however, large deviation exists between the 2-D and 3-D case.
Effects of the Quasi-Biennial Oscillation and Stratospheric Semiannual Oscillation on Tracer Transport in the Upper Stratosphere

Usingsatelliteobservationstogetherwitha chemistry‐climatemodel (CCM),theeffect ofthestratospheric semiannual oscillation (SAO) and quasi-biennial oscillation (QBO) on the equatorial double peak in observed CH4 and NO2 is reexamined. It is concluded that the lower-equatorial Halogen Occultation Experiment (HALOE) CH4 mixing ratio of the April double peak in 1993 and 1995 was associated with the prominent first cycle of the SAO westerlies, which causes local vertical downwelling in the upper equatorial stratosphere. The observational evidences imply that the strong westerlies of the first cycle of the stratospheric SAO in 1993 and 1995 were driven by enhanced lower-stratospheric gravity wave activity in the early parts of those years. The CCM simulations further verify that the gravity wave source strength has a large impact on the development and strength of the SAO westerlies. This result suggests that the equatorial longlived tracer mixing ratio near the stratopause (which is associated with the strength of the SAO westerlies) was not only modulated by the QBO phase, but was also significantly influenced by interannual variation in the gravity waves. It is also found that the deeper equatorial trough of the double peak is unlikely to be always accompanied by the more prominent Northern Hemispheric lobe, and the Northern Hemispheric lobe of the double peak can be mainly attributed to subtropical upwelling. The altitude of greatest chemical destruction anomalies associated with the SAO and QBO is below the trough of the double peak, implying that the effect of the chemical process on the double peak is insignificant.
Naturally Hard Steel Rails: Development and Feedback from Service

Rail life in service can be strongly reduced by both excessive wear and extensive rolling contact fatigue (RCF) damage. Although several solutions exist on the market for premium rails, their use is limited to specific situations where specific needs arise. This work shows the outcomes of the installation of rails manufactured in naturally hard microalloyed steel in two opposite situations, i.e. in the low rail on a metro system (affected by extensive corrugation phenomena) and on the high rail of a conventional mixed-traffic railway (affected by wear and/or RCF damages). Welding procedures are analysed as well, ensuring compatibility with existing rails. Very promising results show that this steel grade could be used everywhere as replacement of the conventional rails made of R260 steel grade.
Self-Reported Experiences of Dating Abuses among College Students in Romantic Relationships

Past researchers have examined the prevalence of dating violence among college-aged students in the United States. Using a self-reported survey of the experiences of current college students, this study analyzed some of the factors related to physical, emotional, and sexual abuses in their romantic relationships. From that analysis, comparisons were drawn with the research from other college-university samples, attempting to describe and explore the problem of violence in premarital relationships. In the sample, race, number of past serious romantic relationships, and frequency of experienced anger was associated with minor physical abuse. Non-involvement in Greek Life was associated with experiencing major physical abuse. Gender, sexual orientation, and current year in school were associated with experiencing sexual abuse. Number of months spent in a most recent romantic relationship, consuming alcohol, and weekly alcohol consumption were associated with experiencing sexual abuse.
SPATIO-TEMPORAL MOBILITY OFAPICULTURE AFFECTED BY THE CLIMATE CHANGE IN THE BEEKEEPING OF THE GULF OF MEXICO

One the effects of climate change on populations has been the alteration in the geographical limits and spatial mobility of plants, which generates changes with associated species, such as honeybees which could produce changes in beekeeping. The aim of this study was to determine the spatio-temporal mobility of beekeeping, in the short, medium and long term, in the main honey-producing area in the Gulf of Mexico`s beekeeping region due to changes in temperature resulting from climate change using a regional assembly model with scenario A2. The productive potential of eight indicator melliferous species was determined: C. sinensis, C. paradisi, B. simaruba, C. arabica, A. germinans, R. mangle, B. nigra and S. mombin. The development potential for A. mellifera was determined based on combining bee thermal comfort and melliferous species’ information, forming four categories for apicultural development. Based on the type of flowering, beekeeping will be confronted by a loss of suitable area for citrus species and an increase in area for the rest of the indicator species, which demonstrated different changes according to each species from the short to the long term. Therefore, beekeeping will have a varied spatio-temporal mobility according to the availability of botanical resources and the thermal comfort of the honeybee.
Phase diagram of vortices in high-Tc superconductors with a melting line in the deep Hc2 region

We use a simple elastic Hamiltonian for the vortex lattice in a weak impurity background, which includes defects in the form of integer-valued fields to calculate the free energy of a vortex lattice in the deep ${H}_{c2}$ region. The phase diagram in this regime is obtained by applying the variational approach of M\'ezard and Parisi developed for random manifolds. We find a first-order line between the Bragg-glass and vortex-glass phases as a continuation of the melting line. In the liquid phase, we obtain an almost vertical third-order glass transition line near the critical temperature in the $H\text{\ensuremath{-}}T$ plane. Furthermore, we find an almost vertical second-order phase transition line in the Bragg-glass as well as the vortex-glass phases, which crosses the first-order Bragg-glass\char21{}vortex-glass transition line. We calculate the jump of the temperature derivate of the induction field across this second-order line as well as the entropy and magnetic-field jumps across the first-order line.
ULTRAVIOLET AND MICROWAVE RADIATION IN TRICHODERMA VIRIDE ISOLATES

This paper aimed to determine the exposition time close to 5% ofsurvival of Trichoderma viride (TSM) under ultraviolet light, and TSM andIT isolates of Trichoderma viride to microwave radiation, in order to obtainthe mutants resistant to benomyl fungicide. This survival was studied fromthe irradiation of conidia at different exposition times. 0.1mL aliquots ofconidia suspension from the isolates were irradiated at time of 5% of survivaland incubated in PDA medium supplemented with doses of 0; 1.0; 5.0; and10 g.mL-1 of benomyl. The results showed that the exposition time ofthe TSM isolate to ultraviolet radiation was about two minutes and formicrowave radiation the time was eight seconds for both TSM and ITisolates. Conidia from IT isolate were more resistant to microwave radiationthan the TSM isolate. Eight resistant mutants to 5.0 g.mL-1 benomylfungicide were obtained from the TSM isolate exposed to ultravioletradiation, both according to the resistance to the fungicide and theantagonism in vitro to phytopathogens, though with different colors ofmycelia. Colonies of mutants resistant to benomyl with the use ofmicrowave radiation were not observed.
Protein import into chloroplasts: an ever-evolving story

Chloroplasts are but one type of a diverse group of essential organelles that distinguish plant cells and house many critical biochemical pathways, including photosynthesis. The biogenesis of plastids is essential to plant growth and development and relies on the targeting and import of thousands of nuclear-encoded proteins from the cytoplasm. The import of the vast majority of these proteins is dependent on translocons located in the outer and inner envelope membranes of the chloroplast, termed the Toc and Tic complexes, respectively. The core components of the Toc and Tic complexes have been identified within the last 12 years; however, the precise functions of many components are still being elucidated, and new components are still being identified. In Arabidopsis thaliana (and other species), many of the components are encoded by more than one gene, and it appears that the isoforms differentially associate with structurally distinct import complexes. Furthermore, it appears that these complexes repres.
Performance and carcass characteristics of Japanese quails fed diets containing Wolffia meal [Wolffia globosa (L). Wimm.] as a protein replacement for soybean meal.

The objectives of this study were to determine the effect of replacement of Crude Protein (CP) from Soybean Meal (SBM) with CP from Wolffia meal [Wolffia globosa (L). Wimm. ] on performance and carcass quality in Japanese quails. Using Completely Randomize Design (CRD), two hundred eighty-eight quails were divided into four treatments. Each treatment consisted of six replicates and each replicate contained twelve quails. The dietary treatments were T1: control diet, T2, T3 and T4: CP from SBM was replaced by CP from Wolffia meal at 25, 50 and 75%, respectively. The results showed that the feed intake of quails significantly decreased (p 0.05) feed efficiency, performance and carcass quality of quails. Skin pigmentation increased (p<0.05) with increasing CP replacement from Wolffia meal. In conclusion, 50% of CP from Wolffia meal could appropriately replace CP from SBM in the diet of quail.
The Impact of E-Commerce Development on Urban Logistics Sustainability

The purpose of the present paper is to present some sustainable solutions for urban logistics. The approach is to identify the present challenges for urban logistics caused by the increase of freight volumes due to the development of e-commerce. To meet them, companies’ sustainable practices were analyzed and the utilization of new electric power train technologies seem to offer interesting results for reducing carbon emission impacts. Using methods of literature review and experiences from ongoing electric mobile research projects, this paper argues that electric vehicles in urban distribution are a yet underestimated element towards more efficient transport processes—hence economic advantages for companies, towards the reduction of a company’s footprint and even towards an increased service level for the customers.
A Broadband Doubly Balanced Monolithic Ring Mixer with a Compact Intermediate Frequency (IF) Extraction

To meet the requirements for broadband operation, high port-to-port isolation, and miniature chip area, a doubly balanced monolithic microwave ring mixer with an advanced IF extraction fabricated using 0.15"m GaAs pHEMT process is presented. A miniature Marchand-like spiral balun with low-pass fllter is used to extract IF signals and maintain balun performance simultaneously. The low-pass fllter can fllter out both the RF and LO signals. This miniaturized mixer design can mitigate layout complexity, improve port-to-port isolations suitable for ultra-broadband Ku-, K-, and Ka- band applications. Subsequently, the LO/RF-to-IF isolations are greater than 43.2 and 32dB from 11 to 40GHz, respectively. The LO-to-RF isolation is between 26.9 and 50.7dB within the same swept range. The conversion loss is 7.2{12.4dB within the operating bandwidth.
Socio-economic impact of biofuel feedstock production on local livelihoods in Ghana

The production of liquid biofuels has become an issue of concern in many developing countries, due mainly to the establishment of large-scale biofuel feedstock plantations. These plantations present potential socio-economic benefits, particularly in terms of agricultural employment, as well as risks. The spread of large-scale commercial production of biofuel crops in Ghana has raised concerns from civil society organizations, local communities and other parties. This paper draws on studies that have been conducted in Ghana to assess the socio-economic impact of large-scale production of biofuel crops, especially Jatropha, on the livelihoods of local communities and people in Ghana, focusing on land grabbing and alienation, impact on food production and security, and impact on employment and income generation. Even though the biofuel industry in Ghana is still in its early stages of development, the paper reveals that commercial biofuel production impacts significantly on the livelihoods of local people.
