Modeling and optimal design of LLC resonant converter using whale optimization algorithm
Authors: Sarath K. S. , Sekar S.
Published: October 2018

Resonant converter (RC) was brought under research in the 80’s widely, which can attain very small switching loss, therefore, facilitating resonant topologies to function at the high switching frequency. It is well addressed in the review that the optimal parameterization of the resonant converter is a crucial task. While the literature has come out with different methodologies, they are highly conceptual and so the uncertainty due to high theoretical impact persists. This paper intends to develop a Parameter Optimization (PO) algorithm for designing and developing of LLC-RC. The proposed algorithm overwhelms the limitation by introducing a nonconceptual model based on the simulated outcome. Specifically, the resonant current under start-up conditions is acquired from the literary outcome, and the intelligent model is constructed. Based on the proposed model, a renowned search algorithm called as Whale Optimization Algorithm (WOA) is exploited to optimize the time constant of the resonant converter, which is a critical design parameter. The objective model is derived as a function of start-up time and so the start-up time can be minimized. Moreover, the response speed of the output voltage is also increased. The proposed Whale Optimization Algorithm based Parameter Optimization (WOAPO) is compared with the conventional techniques such as IAPO, Ant Bee Colony-PO (ABC-PO), Particle Swarm Optimization- PO (PSOPO), FireFly PO (FFPO) and Grey Wolf Optimization (GWOPO). The obtained result verifies the performance of the proposed method in modeling LLC-RC system.

Difficulties in the fabrication of direct interface of ferroelectric BiFeO3on the gate of ferroelectric field effect transistor (FeFET) is well known. This paper reports the optimization and fabrication of ferroelectric/dielectric (BiFeO3/HfO[Formula: see text] gate stack for the FeFET applications. RF magnetron sputtering has been used for the deposition of BiFeO3, HfO2films and their stack. X-Ray diffraction (XRD) analysis of BiFeO3shows the dominant perovskite phase of (104), (110) orientation at 2[Formula: see text] at the annealing temperature of 500[Formula: see text]C. XRD analysis also confirms the amorphous nature of the HfO2film at annealing temperature of 400[Formula: see text]C, 500[Formula: see text]C and 600[Formula: see text]C. Multiple angle analysis shows the variation ion the refractive index between 2.98–3.0214 for BiFeO3and 2.74–2.9 for the HfO2film with the annealing temperature. Metal/Ferroelectric/Silicon (MFS), Metal/Ferroelectric/Metal (MFM), Metal/Insulator/Silicon (MIS), and Metal/Ferroelectric/Insulator/Silicon (MFIS) structures have been fabricated to obtain the electric characteristic of the ferroelectric, dielectric and their stacks. Electrical characteristics of the MFIS structure show the memory improvement from 2.7[Formula: see text]V for MFS structure to 4.65[Formula: see text]V for MFIS structure with 8[Formula: see text]nm of buffer dielectric layer. This structure also shows the breakdown voltage of 40[Formula: see text]V with data retention capacity greater than [Formula: see text] iteration cycles.
Two Tales of Super-Typhoons and Super-Wealth in Northwest Pacific: Will Global-Warming-Fueled Cyclones Ravage East and Southeast Asia?
Authors: Niggol Seo S.
Published: October 2018

This paper examines the impact of the typhoons generated in the Northwest Pacific Ocean and affecting East/Southeast Asia on the number of human fatalities using the typhoon data from 1980 to 2016 and whether future typhoons, likely more intense due to global warming, will dramatically increase human fatalities. The best-track data and the tropical cyclone (TC) reports show that there was no change in the intensity of cyclones during this time period, nor in the number of fatalities. An application of a negative binomial count-data model of the number of TC fatalities shows that the number of fatalities increases by 1.8 percent in response to a one-unit increase in TC intensity, expressed in terms of the minimum central pressure (MCP), but the number of fatalities also decreases by 0.53 percent in response to a one-unit increase in income per capita. In the future year 2100, a 5 millibar decrease in MCP, i.e., an increase in TC intensity, is predicted to increase the number of fatalities by 9 percent from the present fatality value, while a 10 millibar decrease to increase it by 18 percent. However, an increase in income per capita by 1 percent annually coupled with a 10 millibar decrease in the MCP is predicted to decrease the number of fatalities by 59 percent of the present number of fatalities. A surprisingly high income elasticity in the Northwest Pacific is attributed to the difference between Japan and the Philippines, two island nations both heavily affected by typhoons. The income per capita in Japan is more than 20 times than that of the Philippines, which makes the historical number of fatalities in each cyclone landfall more than 20 times smaller in the former, due to superb historical adaptations.
Proteome and transcriptome profiling of equine myofibrillar myopathy identifies diminished peroxiredoxin 6 and altered cysteine metabolic pathways
Authors: Valberg Stephanie J. , Perumbakkam Sudeep , McKenzie Erica C. , Finno Carrie J.
Published: October 2018

Equine myofibrillar myopathy (MFM) causes exertional muscle pain and is characterized by myofibrillar disarray and ectopic desmin aggregates of unknown origin. To investigate the pathophysiology of MFM, we compared resting and 3 h postexercise transcriptomes of gluteal muscle and the resting skeletal muscle proteome of MFM and control Arabian horses with RNA sequencing and isobaric tags for relative and absolute quantitation analyses. Three hours after exercise, 191 genes were identified as differentially expressed (DE) in MFM vs. control muscle with >1 log2 fold change (FC) in genes involved in sulfur compound/cysteine metabolism such as cystathionine-beta-synthase ( CBS, ↓4.51), a cysteine and neutral amino acid membrane transporter ( SLC7A10, ↓1.80 MFM), and a cationic transporter (SLC24A1, ↓1.11 MFM). In MFM vs. control at rest, 284 genes were DE with >1 log2 FC in pathways for structure morphogenesis, fiber organization, tissue development, and cell differentiation including > 1 log2 FC in cardiac alpha actin ( ACTC1 ↑2.5 MFM), cytoskeletal desmoplakin ( DSP ↑2.4 MFM), and basement membrane usherin ( USH2A ↓2.9 MFM). Proteome analysis revealed significantly lower antioxidant peroxiredoxin 6 content (PRDX6, ↓4.14 log2 FC MFM), higher fatty acid transport enzyme carnitine palmitoyl transferase (CPT1B, ↑3.49 MFM), and lower sarcomere protein tropomyosin (TPM2, ↓3.24 MFM) in MFM vs. control muscle at rest. We propose that in MFM horses, altered cysteine metabolism and a deficiency of cysteine-containing antioxidants combined with a high capacity to oxidize fatty acids and generate ROS during aerobic exercise causes chronic oxidation and aggregation of key proteins such as desmin.

Many normal tissues undergo age-related drift in DNA methylation, providing a quantitative measure of tissue age. Here, we identify and validate 781 CpG islands (CGI) that undergo significant methylomic drift in 232 normal colorectal tissues and show that these CGI continue to drift in neoplasia while retaining significant correlations across samples. However, compared with normal colon, this drift advanced (∼3–4-fold) faster in neoplasia, consistent with increased cell proliferation during neoplastic progression. The observed drift patterns were broadly consistent with modeled adenoma-to-carcinoma sojourn time distributions from colorectal cancer incidence data. These results support the hypothesis that, beginning with the founder premalignant cell, cancer precursors frequently sojourn for decades before turning into cancer, implying that the founder cell typically arises early in life. At least 77% to 89% of the observed drift variance in distal and rectal tumors was explained by stochastic variability associated with neoplastic progression, whereas only 55% of the variance was explained for proximal tumors. However, gene–CGI pairs in the proximal colon that underwent drift were significantly and primarily negatively correlated with cancer gene expression, suggesting that methylomic drift participates in the clonal evolution of colorectal cancer. Methylomic drift advanced in colorectal neoplasia, consistent with extended sojourn time distributions, which accounts for a significant fraction of epigenetic heterogeneity in colorectal cancer. Importantly, these estimated long-duration premalignant sojourn times suggest that early dietary and lifestyle interventions may be more effective than later changes in reducing colorectal cancer incidence.

Significance:

These findings present age-related methylomic drift in colorectal neoplasia as evidence that premalignant cells can persist for decades before becoming cancerous.

Data on baseline (antipsychotics-naïve) age, weight, and height, and change in these at 3 subsequent follow-up time points up to 313.6 days (95% CI 303.5–323.7) were collected from 181 risperidone-treated children and adolescents (mean age 12.58 years, SD 4.99, range 2.17–17.7) attending a pediatric neurology clinic in Saudi Arabia. Owing to differences in genotypic distributions in the subsamples, results are reported for the white Arab population (n = 144). Age- and gender-normed body mass index (BMI)-standardized z scores (BMI z) were calculated (LMSgrowth program). Linear regression was performed for baseline weight and BMI z, while change in BMI z was assessed using random effects ordered logistic regression. The following single nucleotide polymorphisms (SNPs) were analyzed: rs7799039 in the LEP promoter, rs1805094 (previously rs8179183), rs1137100 and rs1137101 in the LEPR, and rs1414334 in HTR2C. We found a nominally significant association between rs7799309 and baseline weight, adjusting for height, age, gender, and diagnosis (A/G, p = 0.035, β = –3.62 vs. G/G). The rs1137101 (G/G, p = 0.018, odds ratio [OR] = 4.13 vs. A/A) and rs1805094 C allele carriers (p = 0.019, OR = 0.51) showed nominally significant associations with change in BMI z categories. Our data support and replicate previous relevant associations for these variants (including with weight gain when on risperidone), whilst being the first report of such associations in patients of Arab ethnicity.
Effect of Increased Convection Volume by Mid-Dilution Hemodiafiltration on the Subclinical Chronic Inflammation in Maintenance Hemodialysis Patients

Published: October 2018

Mid-dilution hemodiafiltration (MID) is a dialytic technique that might improve systemic inflammation of patients in chronic hemodialysis (HD) by increasing substitution volumes. To verify this hypothesis, we performed a prospective cross-over study comparing the effect on inflammatory biomarkers of higher convection by MID versus standard convection by post-dilution hemodiafiltration (HDF). Patients under chronic HD were therefore treated by MID and HDF by crossover design. Each treatment period lasted 4 months, with 1 month of wash-out where patients were treated by HD, for a total of 9 months. Primary outcome was the change of serum pre-dialytic C-Reactive Protein (CRP), interleukin 6 (IL-6), IL-1, IL-10, transforming growth factor-β (TGF-β), tumor necrosis factor-α, albumin and pre-albumin. Samples were obtained monthly. Ten HD patients were enrolled (age: 64.9 ± 12.6 years; 70% males; dialytic vintage: 10.6 [2.7–16.2] years). Mean convection volume was 40.1 ± 2.5 L/session in MID and 20.1 ± 2.6 L/session in HDF. A significant reduction of β2-Microglobulin was detected as a result of either treatment. In MID, CRP decreased from 11.3 (3.2–31.0) to 3.1 (1.4–14.4) mg/L (p = 0.007), IL-6 from 12.7 (5.0–29.7) to 8.3 (4.4–14.0) pg/mL (p = 0.003), and TGF-β from 10.6 (7.4–15.6) to 7.4 (5.9–9.3) ng/mL (p = 0.001). A significant reduction of CRP from 8.5 (3.2–31.0) to 4.6 (3.2–31.0) mg/L was also detected in HDF (p = 0.037), whereas no significant reduction of IL-6 (p = 0.147) and TGF-β (p = 0.094) was found. Percentage reduction of IL-6 correlated with mean convective volume in HDF (R = 0.666; p = 0.036) and in MID (R = 0.760; p = 0.020). Therefore, MID and HDF are associated with an attenuation of inflammatory pattern that is correlated with a high convective volume.

Published: October 2018

Background: After undergoing a procedure of pulmonary endarterectomy (PEA), patients with chronic thromboembolic pulmonary hypertension (CTEPH) may still experience reduced exercise capacity. Data on effects of exercise training in these patients are scant. Objectives: To evaluate the effectiveness of exercise training after PEA for CTEPH and if the presence of “residual pulmonary hypertension” may affect the outcome. Methods: Retrospective data analysis of CTEPH patients undergoing inpatient exercise training after PEA. According to predefined criteria, patients were divided into those with (group 1) and without (group 2) a “good” post-surgery hemodynamic response. Assessments of the 6-min walking distance test (6-min walking distance test [6 MWT]: primary outcome) were performed before and after surgery (before training), after training and at 3-month follow-up. Hemodynamic and lung function data were also analyzed. Results: Data of 84 and 26 patients of groups 1 and 2, respectively, were analyzed. After surgery patients showed a reduction in 6 MWT, which significantly reversed after training and further improved at 3 months (p = 0.0001), without any significant difference between groups. The percentage of patients reaching the minimal clinically important difference in 6 MWT was similar between groups. The sig­nificant (p = 0.0001) post-surgery improvement in hemodynamics was maintained at 3 months without any significant difference between groups. New York Heart Association functional class improved in parallel to the hemodynamic improvement. Conclusions: Exercise training in patients with CTEPH after PEA, an inpatient exercise training program, improves exercise capacity for up to 3 months, independently of the post-surgery hemodynamic response.
Surfactant Proteins A and D: Trimerized Innate Immunity Proteins with an Affinity for Viral Fusion Proteins

Published: October 2018

Innate recognition of viruses is an essential part of the immune response to viral pathogens. This is integral to the maintenance of healthy lungs, which are free from infection and efficient at gaseous exchange. An important component of innate immunity for identifying viruses is the family of C-type collagen-containing lectins, also known as collectins. These secreted, soluble proteins are pattern recognition receptors (PRRs) which recognise pathogen-associated molecular patterns (PAMPs), including viral glycoproteins. These innate immune proteins are composed of trimerized units which oligomerise into higher-order structures and facilitate the clearance of viral pathogens through multiple mechanisms. Similarly, many viral surface proteins form trimeric configurations, despite not showing primary protein sequence similarities across the virus classes and families to which they belong. In this review, we discuss the role of the lung collectins, i.e., surfactant proteins A and D (SP-A and SP-D) in viral recognition. We focus particularly on the structural similarity and complementarity of these trimeric collectins with the trimeric viral fusion proteins with which, we hypothesise, they have elegantly co-evolved. Recombinant versions of these innate immune proteins may have therapeutic potential in a range of infectious and inflammatory lung diseases including anti-viral therapeutics.
High-Salt Diet Gets Involved in Gastrointestinal Diseases through the Reshaping of Gastroenterological Milieu
Authors: Li Junyi , Sun Fei , Guo Yanchao , Fan Heng
Published: October 2018

Background: Gastrointestinal (GI) diseases are known to be largely influenced by one’s lifestyle and dietary uptake. A high-salt diet (HSD) is well recognized as a risk factor for cardiovascular complications, hypertension, and metabolic syndromes. However, the relationship between an HSD and the GI system, which is the compartment that comes in direct contact with exogenous stimulants, has not been fully explored. Aims: We seek to better understand the complexity of the pathogenic effects of an HSD in the context of GI disorders. Methods: By searching the PubMed and Web of science, the review of literature was performed using keywords: high-salt and GI, high-salt and immunity, salt and microbiota, salt and hormone. Results: In this review, we concluded that high-salt intake potentially perturbs the local immune homeostasis, alters the gut microbiota composition and function, and affects the endocrine hormone profiling in the GI system. Conclusion: HSD might get involved in GI diseases through the reshaping of gastroenterological milieu, which could help to better understand the complexity of the pathogenic effects of an HSD in the context of GI disorders.
Cholesteryl Ester Transfer Protein Variant (RS1800777) with Liver Histology in Non-Alcoholic Fatty Liver Disease Patients
Authors: Aller Rocio , Izaola Olatz , Primo David , de Luis Daniel
Published: October 2018

Introduction and Aims: Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases ranging from simple steatosis without inflammation or fibrosis to nonalcoholic steatohepatitis and in the Western countries has become one of the most prevalent chronic liver diseases related to metabolic and lipid alterations. Cholesteryl ester transfer protein (CETP) participates in high density lipoprotein (HDL)-cholesterol metabolism. The aim of our study was to investigate the influence of polymorphism (rs1800777) of CETP gene on liver histological changes, biochemical parameters, and serum adipokines levels in patients with NAFLD. Material and Methods: A population of 90 patients with NAFLD was recruited in a cross-sectional study. A biochemical analysis (glucose, c-reactive protein, insulin, homeostasis model assessment-insulin resistance, total cholesterol, low density lipoprotein (LDL)-cholesterol, HDL-cholesterol, triglycerides blood, and adipokines (leptin, adiponectin, and resistin) was realized. Genotype of polymorphism (rs1800777) of CETP gene was studied. Results: Eighty-three patients (92.2%) had the genotype GG (wild type group) and 7 patients (7.8%) had the genotype GA (n = 7) or AA (n = 0; mutant type group). Patients with A allele show significant decrease in liver biochemistry parameters – Alanine amino transferase (delta 10.1 ± 9.9 UI/L; p = 0.01), aspartate aminotransferase activity (delta 13.3 ± 9.5 UI/L; p = 0.02), and gammaglutamine transferase levels (delta 39 ± 30.1 UI/L; p = 0.01). Logistic regression analysis indicated that subjects with A-allele carriers were associated with a decreased risk of lobulillar inflammation (OR 0.18, 95% CI 0.04–0.95, p = 0.04) and a decreased risk of steatosis (OR 0.13, 95% CI 0.02–0.89, p = 0.04). Conclusions: A variant of the polymorphism rs1800777 of CETP gene is independently associated with the presence of steatosis and lobulillar inflammation in subjects with proven biopsy NAFLD.

Published: October 2018

Diversos parâmetros têm sido utilizados para a classificação dos meteoritos de ferro, principalmente sua mineralogia e suas propriedades químicas e estruturais. Este artigo resgata e documenta o achado do meteorito férreo Palmas de Monte Alto, apresentando uma sequência de parâmetros classificatórios que amplia e detalha os dados disponíveis sobre o fragmento. Esse meteorito, um siderito, foi achado no topo da serra de Monte Alto antes de 1955 e hoje representa um dos seis espécimes que compõem a coleção de meteoritos do estado da Bahia. Ele é constituído de uma única massa de 97 kg com alto estágio de oxidação externa em locais em que a crosta de fusão foi removida. Sua mineralogia inclui kamacita, taenita e plessita, bem como fases minerais secundárias, tais como o óxido de Fe-Ni akaganeíta. Também estão presentes minerais acessórios de ocorrência comum em ligas metálicas de Fe-Ni de origem espacial, isto é, schreibersita, cromita e troilita, e foi identificada uma rara solução sólida de ortofosfatos de Fe-Mn composta dos minerais heterosita-purpurita ou sarcopsida-graftonita como membros extremos. A largura média de suas lamelas de kamacita (0,95 ± 0,15 mm) permite classificar estruturalmente o meteorito como um octaedrito médio, com padrão Widmanstätten médio e bem definido. Seus teores de Ni (9,40 wt%) e Co (0,46 wt%) comparados aos elementos-traço Ga (22 ppm), Ir (0,70 ppm), As (16,00 ppm) e Au (1,70 ppm) recomendam a inclusão desse meteorito no grupo químico IIIAB.
Antipoesia e a realidade estilhaçada
Authors: Azevedo Dora Savoldi da Rocha
Published: October 2018

O presente trabalho propõe a análise de “Solo de piano”, antipoema de Nicanor Parra, a fim de discutir mais amplamente algumas questões que palpitam na antipoesia. Por meio de uma construção metonímica, a que se pode aludir nos diversos âmbitos que o configuram, “Solo de piano” materializa a profunda dissonância entre homem e mundo; a cisão e a distância entre os indivíduos nas sociedades modernas; e o esfacelamento de uma concepção de totalidade quanto ao mundo e à vida, cuja abrangência integral se torna impossível. Aqui se analisa, portanto, o esforço antipoético no sentido da refuta ao falseamento da realidade observável, o que acaba por se encaminhar à negação do campo lírico tal qual tradicionalmente estabelecido, à rejeição do sublime. Além disso, fundamentando-se na linguagem popular e estabelecendo uma alteridade com a qual dialoga o sujeito poético, a composição analisada permite vislumbrar a preocupação da antipoesia em se aproximar do povo, expandindo, portanto, o público ao qual se dirige. Pretende-se, enfim, discutir de que modo “Solo de piano” e, de maneira geral, o próprio movimento antipoético configuram uma resposta à fragmentação da experiência humana no mundo contemporâneo.

Published: October 2018

Este ensaio tem como objetivo discutir aspectos da poesia inicial de Jorge Luis Borges, a partir da leitura de um dos poemas presente em Fervor de Buenos Aires, primeira reunião poética publicada pelo escritor argentino. Buscou-se, com o esforço de interpretação do poema “Arrabal”, compreender melhor os elementos principais do primeiro momento de Borges, enquanto poeta, não ignorando as particularidades desse texto, central no livro em que se encontra. Além disso, no presente trabalho é feita uma breve análise do lugar da produção poética inicial borgeana no contexto literário argentino, detendo-se na relação que mantém a poesia do escritor com o período das vanguardas e com a tradição letrada de seu país. Isso é, esse estudo busca delimitar e compreender os motivos formais e temáticos no primeiro livro do escritor portenho, relacionados, respectivamente, à construção de imagens nacionais da Argentina, a partir de sua capital, e à estética ultraísta, a qual manteve certa influência sobre o escritor no início de sua carreira.
O sagrado e o profano na urbanidade: Borges — Análise do poema "Carnicería"
Authors: Andrade Victor De Lima Torquato de
Published: October 2018

Este ensaio lança luz ao desdobramento dialético do sagrado e do profano contidos no poema "Carnicería", já que a análise de tal binômio é capaz de evidenciar a forma como Borges rompe com tradições acerca de imagens comuns da urbanidade: sejam elas uma rua, um açougue ou uma casa de prostituição. E é justamente no momento em que colocamos a lupa científica sobre esta quebra de tradições que vemos surgir o sangue vanguardista do poeta: vemos o transmutar de conteúdos semânticos, as surpresas advindas das articulações entre o antigo e o novo, e uma singular redefinição estética. Ademais, a presente análise procurou respeitar a dinâmica do olhar: cada verso foi analisado na própria sequência do poema, assim, mantendo-se fiel à sucessão de imagens que o poeta construiu, buscando mimetizar o gesto de ler o poema, e de se pensar enquanto se lê.

A erótica vanguardista de Oliverio Girondo
Authors: Verneck Bruno
Published: October 2018

O presente texto tem por objetivo discutir o poema “Biarritz” do escritor argentino Oliverio Girondo, pensando sua forma a partir das premissas vanguardistas amplamente difundidas na América-Latina nas primeiras décadas do século XX. Para tal, procura analisar a poética do fragmento, presente no trabalho do escritor argentino, como um traço das diversas modalidades e disciplinas em que as vanguardas históricas se manifestaram. Nos 20 poemas para ser leídos en el tranvía, o trabalho com o fragmentário possibilita a construção das imagens do erótico que permeiam o livro. A presente leitura busca compreender de que modo, ao construir o olhar do eulírico nestes poemas, Girondo articula a experiência da modernidade à discreta obsessão pelos corpos femininos. Por fim, tendo em vista o forte caráter interdisciplinar das vanguardas históricas, o texto se debruça sobre os desenhos do autor que ilustram a obra para buscar continuidades com relação à construção imagética de seus poemas.
O antiflâneur de “Walking Around”: errância e estranhamento na cidade
Authors: Franco Carla Cancino
Published: October 2018

A poesia do século XIX consagrou como um de seus arquétipos literários representativos a figura do flâneur, caminhante observador que encarna o espírito do homem curioso que, sem destino certo, vaga pela cidade surpreendido com a variedade da paisagem urbana. O flâneur ganhou destaque na poesia de Charles Baudelaire. No século XX, mais precisamente no poema “Walking Around”, Pablo Neruda redesenha os contornos do flâneur, a partir do olhar da vanguarda. Ressurge nos versos do poeta chileno a figura do homem que caminha pela cidade. Este, porém, diferente do andarilho do século anterior, já não é um observador apaixonado, mas um antiflâneur. Sua relação com o espaço urbano não é mais de admiração, mas de choque permanente. A sintonia passou à dissonância; a curiosidade deu lugar ao estranhamento e o deleite do ócio tornou-se cansaço. O poeta, antes observador unilateral, sofre agora a ação dos objetos do mundo, sentindo o cansaço, a angústia e a culpa de seu tempo.

Authors: EŞİTTİ Bekir , BULUK Buket
Published: October 2018

The purpose of this study is to determine the potential effects and expectations of ‘The Year of Troy’ on attracting tourists and sustainable growth of Canakkale. In accordance with these purposes, promotional activities and events carried out within the scope of ‘The Year of Troy’ were evaluated. In addition, interviews were held with stakeholders and national-international tourists participating in the events. Interviews were conducted face-to-face by applying a semi-structured in-depth method. As a result, it can be said that the interest of Canakkale in the national and international area has increased remarkably in the first half of the year with the declaration of 2018 as the Year of Troy. Local stakeholders are very hopeful about the positive impact of ‘The Year of Troy’ on Canakkale’s tourism and are continuing to work in this direction. It is also seen that the local stakeholders continue to be supported by the national government. It can be said that this support is an important determinant in the unification of local stakeholders and the revival of local tourism. It is necessary for national and local unity to be maintained and long-term growth plans to be carried out for the sustainability of this revival.
FİNANSAL GELİŞMENİN VE ENERJİ TÜKETİMİNİN KARBONDİOKSİT EMİSYONLARI ÜZERİNDEKİ ETKİSİNİN ÇEVRESEL KUZNETZ EĞRİSİ ÇERÇEVESİNDE DEĞERLENDİRİLMESİ

Küresel iklim değişikliği
insanlığı tehdit eden en önemli sorunlardan biri konumundadır. Bilimsel
araştırmalar, iklim değişikliğine ve küresel ısınmaya neden olan sera gazı
emisyonlarının en önemli kaynağının karbon dioksit (CO2) emisyonları
olduğuna işaret etmektedir. Bu çalışmada G7 ülkelerinde finansal gelişmişlik ve
karbon emisyonları arasındaki ilişki ÇKE hipotezi çerçevesinde yatay kesit
bağımlılığını ve eğim heterojenliğini dikkate alan yeni panel veri tahmincileri
kullanılarak araştırılmaktadır. Çalışmada, çevresel bozulmanın ölçütü olarak
kişi başına düşen karbon emisyonu, finansal gelişmeyi temsilen ise yurtiçi
kredi hacmi kullanılmıştır. Elde edilen bulgular, finansal gelişmenin ve enerji
tüketiminin karbon emisyonlarına önemli ölçüde katkıda bulunduğunu
göstermektedir. Son olarak, çevre ekonomisi literatüründe önemli bir yeri olan ÇKE
hipotezi G7 ülkeleri için test edilmiş; hipotezin panelin geneli için geçerli
olmasa da, statik modelde 2 ülke ve dinamik modelde üç ülke için geçerli olduğu
sonucuna ulaşılmıştır.

Published: October 2018

Finansal
gelişmişlik dünya ülkelerinin ekonomik açıdan büyümelerine öncülük eden
kavramlardan biridir. Finansal gelişmişliği arttırmak için ülkelerin istikrarlı
bir finansal sisteme sahip olmaları gerekmektedir. Etkin finansal sisteme sahip
olabilmek için bankalar ve sermaye piyasalarının işleyişi oldukça önemlidir. Bu
çalışmada OECD ülkelerinin finansal gelişmişlik düzeyleri ölçülmüştür. Bu ölçüm
endeks oluşturarak yapılmıştır. Çalışma 1980-2015 yılları arasını
kapsamaktadır. Bu çalışmanın amacı; finansal gelişmişlik endeksi oluşturarak
ülkelerin finansal açıdan durumlarını incelemek ve ülkeler arası kıyas yapmaktır.
Bu amacı gerçekleştirmek için Topsis yönteminden yararlanılmıştır. Topsis
yöntemi yardımıyla ülkelerin finansal gelişmişlik skorları hesaplanmıştır.
Araştırmanın sonucunda; 1980-2015 yılları arasında finansal açıdan en gelişmiş
ülkenin Japonya olduğu, ABD ve İsviçre’nin de o seviyeye yaklaştığı
görülmektedir.
BARRIERS TO THE USE OF INTERNET BANKING AMONG NIGERIAN AND ZIMBABWEAN STUDENTS IN NORTHERN CYPRUS
Authors: SERENER Berna
Published: October 2018

The purpose
of this paper is to analyse the factors preventing Nigerian and Zimbabwean
university students from adopting internet banking services in Northern Cyprus.
A survey was conducted to acquire data from one hundred Nigerians and one
hundred Zimbabwean university students attending a private university in
Northern Cyprus.  Factor analysis results
showed that the most important factor linked to the rejection of the usage of
internet banking services among Nigerian and Zimbabwean students were people’s
fears of the risk associated with such services.  This was followed by students’ preferences to
traditional banking practices, value barriers, infrastructure barriers,
government obstacles and usage barriers. 
In order to compare the differences between the aforementioned factors
for Nigerian and Zimbabwean students, independent samples t-tests were
conducted.  The study found that there
was a significant difference between the Nigerian and Zimbabwean student’s preference for traditional
banking practices, infrastructure and government obstacles. Interestingly,
there was no significant difference between the Nigerian and Zimbabwean
student’s fears over the risk associated with internet banking, perceptions of
its value and usage barriers.

Authors: ORHAN Ayhan , YILMAZ GENÇ Sema
Published: October 2018

Gelişen ekonomilerde, sosyoekonomik ve toplumsal alanlarda yaşanan dönüşümün
yeni kaynağı teknolojik gelişmedir. Son yıllarda artan teknolojik gelişmeler bu
süreci karmaşık bir boyuta taşımıştır. Günümüz toplumlarının küresel düşünce
ağı çerçevesinde bu gelişmeleri ölçeklendirip sosyoekonomik yaşama
yansıtmasının zamanı gelmiştir. Yeni ekonomi olarak da algılanan bu süreç,
küreselleşme sonrası ortaya çıkan deneyimlerin dikkatlice incelenmesine ve
sebep sonuç ilişkilerinin değerlendirilmesine olanak sağlamıştır.

Özellikle gelişmiş ülkelerde başlayan bu deneyim, bilgi teknolojilerinin
ve iletişim ağının gelişmesine yardımcı olurken, diğer taraftan ülkeler arası
küresel rekabeti dönüştürerek uluslar üstü firma rekabetinin önünü açmıştır. Dünya
ekonomisinde yaşanan bu hızlı değişim sonrasında küresel rekabete yeni bir
boyut kazandıran teknolojik gelişmelerin,
ekonomik kuralların ve kurumlarının dönüşüm sürecini de hızlandırmıştır. Bilgi
ve iletişim teknolojilerindeki bu dönüşüm özellikle gelişmekte olan dünya
ekonomilerinde kalıcı ve belirgin bir kavramsal çerçevenin oluşmasını
sağlamıştır.

Bu çalışma ile bilgi ve iletişim teknolojilerinin kavramsal çerçevesi,
dönüşümü sağlayan belirteçleri ve sonuçta yaşanan bu gelişmelerin, sosyoekonomik
etkilerini içeren unsurların ortaya konulmasını sağlayan değerlendirmeleri
içerecektir.
The Ecological, Economic, and Cultural Legacies of the Mule in Southeast Brazil
Authors: Hickie Mark M. , de Oliveira Rogério Ribeiro , da Costa Quinteiro Mariana Martins
Published: October 2018

Resulting from cross-breeding a horse and a donkey, the mule influenced southeast Brazil’s economic development perhaps more so than any other domesticated animal; the mule served as the key transport vehicle during both Brazil’s 18th century gold era and 19th century coffee era. In enabling mining and agriculture products to traverse mountainous terrain to reach port cities near São Paulo and Rio de Janeiro, the mule played a central role in the region’s economic and ecological history. Although the mule has not been southeast Brazil’s primary transport method since the train’s arrival in the 1870s, rural and urban dwellers still employ the mule over short distances near two protected landmasses despite declining generational interest and use. More recently, with increasing leisure use as a companion animal, the mule stimulates tourism and local economic patterns via large gatherings while serving as a cultural symbol of Brazil’s patrimony.

Published: October 2018

Collections identified as “S. placidus” from the south of China, a subtropical/tropical region, were investigated using morphology and phylogenetic analyses of DNA sequences from nuc rDNA internal transcribed spacer (ITS). The results indicated that these specimens from subtropical/tropical China are not true S. placidus but represent a new species. Suillus huapi sp. nov. is characterized by a yellowish white to grayish yellow pileus when young, brown to dark brown when old, surface of pores and stipe usually beaded with droplets of milky liquid when young, a stipe without obvious granules, a pileipellis as an ixocutis, and an association with two-needled pines including P. caribaea, P. massoniana and P. yunnanensis.
Solving a nomenclatural conundrum: Cernosvitovia crainensis (Mršić, 1989) and Aporrectodea macvensis Šapkarev in Mršić, 1991 (Lumbricidae)
Authors: NICOLSON DAVID , CSUZDI CSABA
Published: October 2018

This contribution deals with the names and authorship of two lumbricid taxa endemic to the Balkans (see Stojanović et al., this volume). Although their validity has never been questioned, it has been unclear up to now which publication has made these two species-group names available according to the rules of the International Code of Zoological Nomenclature (Articles in "the Code," ICZN 1999). In the following, we review the somewhat intricate history of these names and explain why the correct citation and spelling of these names are "Cernosvitovia crainensis (Mršić, 1989)" and "Aporrectodea macvensis Šapkarev in Mršić, 1991," respectively.

Published: October 2018

The early scientists who studied the earthworm fauna of Bulgaria were Rosa (1897), Černosvitov (1934), and Mihailova (1966). Their work was continued by Šapkarev (1986) and Zicsi and Csuzdi (1986). In the last decade, researchers from Hungary, Serbia and Bulgaria organized explorations of many localities and enhanced the knowledge of the earthworm fauna of the country (Valchovski 2012, Stojanović et al. 2012, Szederjesi 2013). The present paper summarizes the new species records after these aforementioned three publications: Cernosvitovia munteniana, Eisenia andrei, Murchieona minuscula, Proctodrilus opisthoductus and Dendrobaena veneta.
The first proandric species of Tritogenia Kinberg, 1867 from Botswana, Tritogenia talana sp.n. (Clitellata, Crassiclitellata, Tritogeniidae)

Published: October 2018

The earthworm fauna of Botswana is hitherto unknown. A first collecting trip to the regions of Chobe and Tuli Block resulted in the discovery of a new species, Tritogenia talana sp.n. Its reproductive organs show some level of degeneration when compared to other species of Tritogenia. The spermathecae were not observed, testes and sperm funnels are in proandric condition and seminal vesicles are absent. This is the first record of an earthworm species from Botswana.
Morphological and molecular evidence reveal a new species of the earthworm genus Pontodrilus Perrier, 1874 (Clitellata, Megascolecidae) from Thailand and Peninsular Malaysia

Published: October 2018

A new species of the megascolecid earthworm genus Pontodrilus Perrier, 1874, Pontodrilus longissimus sp. n., is described from seashores of Thailand and Peninsular Malaysia. The new species differs from congeners, especially the cosmopolitan P. litoralis (Grube, 1855) in the size of the body, number of segments and the shape of the spermathecae. P. litoralis is redescribed, based on specimens collected from the same region and the same type of habitat. DNA fragments of the mitochondrial cytochrome oxidase subunit I of both species were sequenced. Morphological as well as DNA sequence-based comparisons confirm that P. longissimus sp. n. is a lineage distinct from P. litoralis and in fact a new species. The illustrated descriptions are accompanied by a key to species of Pontodrilus.
Two new Mesenchytraeus species (Annelida: Clitellata: Enchytraeidae) from Changbai Mountain, China
Authors: ZHANG JUNQIAN , LU YAJING , XIE ZHICAI
Published: October 2018

The Changbai Mountain in northeast China harbours a species-rich enchytraeid fauna, and ca. 50 species of 11 genera have been reported so far from its well-preserved ecosystems. Herein, we add two new species of Mesenchytraeus into this enchytraeid list. Both members belong to the lineage of Mesenchytraeus with enlarged ventral chaetae. Mesenchytraeus spermatoglomeratus sp. nov. is characterized by the presence of enlarged chaetae in V–VI and XI (2 per bundle), five pairs of preclitellar nephridia (VI/VII–X/XI), sperm sacs containing curly ball-shaped sperm bundles, spermathecae without diverticula, atrium with 4–6 developed prostate glands and long vasa deferentia backward to XV–XXII. Mesenchytraeus liberothecus sp. nov. is diagnosed by the presence of enlarged chaetae in V–VI (2 per bundle), five pairs of preclitellar nephridia (VI/VII–X/XI), asymmetrical paired sperm sacs containing flame-shaped sperm bundles, spermathecae with two small diverticula but free from oesophagus, atrium with 4–5 large prostate glands and short vasa deterentia confined to XI and XII. The major differences between the new species and their congeners are discussed. We also add them into the key of this enlarged chaetae lineage.
Observations on an epilobic Lumbricus rubellus (Oligochaeta, Lumbricidae) from the Great Smoky Mountains National Park, Tennessee, USA
Authors: CARRERA-MARTÍNEZ ROBERTO , CALLAHAM MAC A. JR.
Published: October 2018

The genus Lumbricus L. was the first described genus of earthworms, with L. terrestris as its type species. The genus can be easily distinguished because it is the only lumbricid genus with a tanylobic prostomium, with the exception of the North American native Bimastos eiseni (Levinsen). With six known Lumbricus species introduced in North America (Reynolds & Wetzel, 2012), Lumbricus rubellus is one of the most widespread. In addition, L. rubellus has been associated with negative ecological effects as result of its invasion (Greiner et al. 2012). The Great Smoky Mountains National Park in Tennessee and North Carolina, USA, is no exception from earthworm invasions (Snyder et al. 2011). Recent research in an area near the extreme southwestern end of the Park (35.5538º N; 83.9943º W), resulted in the collection of ten specimens of L. rubellus, on 27 July 2011. Among these specimens was one that had an abnormal epilobic prostomium and under-developed tubercula pubertatis, whereas the rest had the typical Lumbricus tanylobic prostomia and fully developed tubercula pubertatis. To facilitate discrimination and identification in future encounters of an epilobic L. rubellus we provide here a full description of this specimen. To our knowledge, this is the first reported case of a specimen of L. rubellus with an epilobic prostomium. The specimen will be deposited in the nascent Terrestrial Oligochaete Collection at the Georgia Museum of Natural History in Athens, Georgia, USA. The specimen was fixed in 10% formalin, and is preserved in 70% ethanol.
New Diplotrema and Lavellodrilus earthworm species from southern Mexico (Annelida, Crassiclitellata, Acanthodrilidae)
Authors: FRAGOSO CARLOS , ROJAS PATRICIA
Published: October 2018

Two acanthodriline new species from the states of Tabasco and Chiapas in southern Mexico are described, Diplotrema chajulensis sp. nov. and Lavellodrilus sheylae sp.nov. Diplotrema chajulensis sp. nov. has spermathecae where the ampulla inserts at a right angle from the duct and the diverticulum continues the main axis; it is distinguished from other neotropical Diplotrema species that share this character by the pattern of genital marks and the type of penial setae. Lavellodrilus sheylae sp. nov. is unique in the genus Lavellodrilus by the unpaired condition of the mesial spermathecae; variation in the number of spermathecal diverticula (one or two) was considered a polymorphism. Finally we discuss reasons to maintain one of the new species in an austral genus (Diplotrema) in spite of some morphological differences observed among the Mexican-Cuban-Central American (MX-CA) worms and the austral species. A short esophagus in all the holoic and meroic acanthodriline earthworms from MX-CA and a mid-ventral position of spermathecal pores in Lavellodrilus are interpreted as ancestral characters that evolved and were fixed in the worms that inhabited an ancient Laurasian block, probably in response to the semi-aquatic conditions that prevailed in this region during millions of years.
