Nursing Students' Perception of Medical Information Protection in Hospitals
Authors: Jeong Hyeon-Cheol
Published: August 2018

The purpose of this article is to investigate the perception of medical information protection. The subjects were 281 students from 2 nursing students from September 1, 2015 to October 20, 2015. A total of 28 self - administered questionnaires were used. As a result, the perception of medical information protection behavior was 3.39 ± 0.51. In the fourth grade, the 'privacy protection' category was low (p = .007) and the 'communication' category was high (p = .045). In case of having experience in practice, 'privacy protection' category (p = .010) and ‘medical information management' category (p = .041) were low and 'communication' (p = .021) was high. In the 'communication' category, the perception score was high when the medical information protection law (p = .001) and the nurses' code of ethics (p = .040) were known. When the subject completed 'medical security education' (p = .004), the perception was high. In conclusion, it is necessary for schools and medical institutions to develop nursing education programs for their educational environment and role.

Published: August 2018

Background: Complexities generally are conundrums that inhibit efficiency and effectiveness in research and practice; one of the symptoms of this is nebulous obstruction to task completion in the workplace. Complexities in work procedures create complications in the application of procedures for completing tasks. Recent trends in the Auditor General’s report have demonstrated the metastasising culture of non-compliance to work procedures in municipalities in South Africa. Research, as well as the audit outcomes for the Eastern Cape in particular, is a testament to this assertion. Therefore, there is no need to make work more complex. Aim: To ascertain whether the application of Taylorism in the workplace could improve performance and to access the utilisation of work procedure in municipalities in the Eastern Cape. Setting: This study was carried out using quantitative data collected from a District Municipality and its five local municipalities at the Transkei area of the Eastern Cape, South Africa. Method: A survey completed by 593 municipality workers (junior workers) was collected and analysed using statistical methods and triangulation. Results: Findings from the article reveals that work procedures in the organisation might be old and archaic. It may be relevant to workers who have little or no interference from externalities with regard to their job commitments. It recommends that those officials that perform routinised functions in municipalities should use a work procedure manual when completing their task. Based on the notion that work procedures engender compliance, increase outcome and output, increase productivity, save time, reduce stress and organisational friction or conflict in organisations. Conclusion: It concludes that procedures that are comprehensible (simple), accessible (organically inputted and communicated) and accurate (effectively designed) will improve the daily functionality of lower echelon staff in the municipalities, especially those requiring little or no external influence on the completion of a task.

Authors: Prakash A Ravi , Simha Reddy A Vikram Simha , Killampalli Lakshmi Keerthana , Rajinikanth M
Published: August 2018

Ewing's sarcoma is rare sarcoma of bone and soft tissue that uncommonly involve the head and neck in both bone and soft tissue locations. The term Ewing's sarcoma family of tumors comprises both Ewing's sarcoma and peripheral neuroectodermal tumor. It was in 1975, Angervall and Enzinger described the Ewing's sarcoma arising in soft tissues (extraskeletal). The principal sites of extraskeletal Ewing's sarcoma are the paravertebral region and chest wall, generally in close association with vertebrae or the ribs. These tumors may also arise in the soft tissues of the lower extremities and rarely in the pelvic region and hip regions. Superficially located cases do occur but are rare. Here, we present a case of Ewing's sarcoma involving the maxillary sinus region. A 12-year-old boy reported to our department with a swelling on the right side of middle third of the face for 15 days. Intraorally, there was only obliteration of the labial vestibule. On histopathological examination, a provisional diagnosis of malignant round cell tumor was given. Immunohistochemistry with a panel of markers was done to come to a definitive diagnosis. CD99 positivity confirmed the diagnosis of Ewing's sarcoma.

Published: August 2018

Precursor B-cell lymphoblastic lymphoma (LBL) occurring as a primary bone tumor is a rare clinical presentation in children, and data regarding this condition are limited to small case series or a few individual case reports. We report two pediatric cases of precursor B-cell LBL of the bone. The tumor cells from bone biopsies of both patients were seen to be positive for leukocyte common antigen (LCA), terminal deoxynucleotidyl transferase, CD10, CD20 and weakly positive for CD99. Bone marrow studies were normal. They were treated according to the modified Berlin-Frankfurt-Münster acute lymphoblastic leukemia high-risk protocol. The first patient has completed treatment including local radiotherapy and has been disease free for the past 10 years. The second patient has recently completed treatment and shows good response.

Authors: Shah Afsana , Jena Nihar Kanta , Shukla Pragya
Published: August 2018

Introduction: The aim of the study was to evaluate the prognostic significance of histopathological differentiation in treatment outcome of locally advanced carcinoma cervix. Materials and Methods: This retrospective study includes 167 patients of locally advanced carcinoma cervix treated between January 2006 and December 2008 who have received definitive chemoradiation. Results:: The number of patients with well (85 [50.9%]) and moderately differentiated (76 [45.5%]) carcinoma was nearly equal with poorly differentiated variety having only 6 (3.6%) patients. On completion of treatment out of the 167 patients, 133 (79.6%) had a complete response and 34 (20.4%) had residual disease. On mean follow-up of 11 months, 19 (14.2%) patients had local and 5 (3.7%) had a distant relapse. Histopathological differentiation and age had no association with treatment outcome, whereas early-stage disease showed trend favoring better treatment response. Conclusion: Advanced stage along with poor histopathological differentiation influences the aggressiveness of the tumor responsible for distant relapse. However, histopathological differentiation has no correlation with local treatment response and overall survival. The main factor influencing the treatment outcome is the intrinsic radiosensitivity of the tumor and volume of the disease.

Published: August 2018

Introduction: Obesity has been associated with the development of breast cancer. The objectives were to study the association of serum adiponectin, serum leptin, and adiponectin–leptin ratio (ALR) in patients with breast cancer and matched controls, and to study their relationship with the various clinicopathological characteristics of breast cancer. Materials and Methods: A prospective, hospital-based case–control study was conducted on 40 patients with a first-confirmed histopathology diagnosis of breast cancer and 40 controls comprising individuals without a history of cancer simultaneously recruited from the health examination clinics during the same study period. Serum adiponectin and leptin concentrations were measured in a single run using commercially available kits (Human ADP/Acrp30 [adiponectin] enzyme-linked immune-sorbent assay [ELISA] kit and Human Leptin ELISA kit, Elabscience Biotechnology Co., Ltd) according to the manufacturer's instructions. Results:: Serum adiponectin levels were reduced significantly in breast cancer patients, in comparison to controls (P = 0.04), while serum leptin levels were increased significantly in breast cancer patients, in comparison to controls (P = 0.03). ALR was significantly lower in breast cancer cases, in comparison to controls (P = 0.05). There was no correlation between receptor status (estrogen receptor, progesterone receptor, Her2/neu), aggressiveness of disease in terms of tumor size, nodal metastases, stage, tumor grade, and serum adiponectin levels, leptin levels, or ALR. Body mass index was negatively correlated with serum adiponectin levels and ALR (r = 0.33, P = 0.03; r = 0.39, P = 0.01, respectively) and positively correlated with serum leptin levels (r = 0.34, P = 0.02). Conclusion: In summary, our results suggest that low serum adiponectin levels, ALR, and high serum leptin levels are associated with breast cancer.

Published: August 2018

Schwannomas are benign, slow-growing, and encapsulated tumors deriving from the perineural cells located in the nerve sheath. They can arise from any peripheral, cranial, or autonomic nerves and show a predilection for the head and neck region. Extracranial head and neck schwannomas are rare tumors. They may produce secondary symptoms such as nasal obstruction, dysphagia, and hoarseness of voice depending on the location of the tumor. The preoperative diagnosis is difficult. Although preoperative imaging or fine needle aspiration cytology may help to reveal diagnosis, they are inadequate. The definitive diagnosis is made by histopathological examinations.

Authors: Kodidela Sunitha , Pradhan Suresh Chandra , Dubashi Biswajit , Basu Debdatta
Published: August 2018

Aim: We aim to establish the genotype and haplotype frequencies of folylpolyglutamate synthase (FPGS rs10106 and rs1544105) and gamma-glutamyl hydrolase (GGH rs3758149 and rs11545078) variants in the South Indian population (SI) and to study the association of these variants with susceptibility to acute lymphoblastic leukemia (ALL). We also aim to compare the genotype and haplotype frequencies of studied variants with those of superpopulations from the 1000 Genomes Project collected in phase-3 and other published studies in the literature. Materials and Methods: A total of 220 unrelated healthy volunteers and 151 patients with ALL of both sexes were recruited for the study. Extracted DNA was subjected to genotyping by allelic discrimination using quantitative real-time-polymerase chain reaction. Genotype details of the studied variants in other ethnicities were obtained from 1000 genomes project Phase 3 data. Haploview software was used to construct haplotypes. Results:: In our study, the frequencies of FPGS rs1006'G' and rs1544105'A' alleles were found to be 37% and 37.2%, respectively, and the frequencies of GGH rs3758149'T' and GGH rs11545078'T' alleles were found to be 29.8% and 16.7%, respectively. Among the studied variants, FPGS rs1544105'AA' genotype carriers were found to be susceptible to the risk of ALL (odds ratio: 2.16; 95% confidence interval [CI]: 1.15–4.07; P = 0.02). Haplotype structures of FPGS and GGH variants in SI population were significantly different from other ethnicities (P < 0.05), except the South Asian superpopulation. Conclusion: FPGS rs1544105'AA' genotype was found to influence the risk for ALL. Intra and interethnic differences exist in the distribution of studied variants. Therefore, the impact of each variant on the susceptibility and outcome of diseases may differ between populations.

Published: August 2018

Introduction: Oral cancers are among the most common cancers in the Indian subcontinent and tobacco is the most common implicated etiologic agent for these cancers. Over last two decades, significant changes have occurred in the lifestyle of people in the subcontinent. Antitobacco legislations have made developed and awareness about the harmful effects of tobacco and related products have increased. We hypothesized that this would lead to change in tobacco use pattern and hence impact the trends of oral cancer in India. Methodology: We analyzed the hospital records of patients having buccal mucosa and tongue cancers at a tertiary care cancer center. We noted the trends of patients presenting with these cancers 4 yearly, over a period of 16 years and in this way tried to assess the impact of legislation and awareness activities upon cancer incidence and trends. Results:: This study has shown that the number of patients presenting with tongue and buccal mucosa cancers has not decreased over the years. Increase in buccal mucosa cancers is marginally more than that of the tongue cancer. Proportion of males with respect to females presenting with these cancers has increased. There has been no significant decline in the younger patients presenting with these cancers. Common age of presentation of tongue cancers has come down. Conclusion: The findings of this study highlight the ineffectiveness of current laws and awareness programs in reducing the menace of oral cancer.

The Bethe algebras for the Gaudin model act on the multiplicity space of tensor products of irreducible

\mathfrak{gl}_r

-modules and have simple spectrum over real points. This fact is proved by Mukhin, Tarasov and Varchenko who also develop a relationship to Schubert intersections over real points. We use an extension to

\overline{M}_{0,n+1}(\mathbb{R})

of these Schubert intersections, constructed by Speyer, to calculate the monodromy of the spectrum of the Bethe algebras. We show this monodromy is described by the action of the cactus group

A multi-biomarker approach was used to evaluate the liver health of two Neotropical fish species (Cathorops spixii and Atherinella brasiliensis) that inhabit two different sites of the Paranaguá bay (Paraná – Brazil) and a reference site in the Garatuba bay. Fish were sampled during summer and winter, so the variation of the responses can reflect the actual conditions of sampling sites. Data showed that fish from both sites of the Paranaguá bay are affected by the presence of pollutants from different sources. Both fish species presented adverse biomarker responses mainly in the summer, probably due to the increased human population during the period. Chronic effects in the liver related with the contamination. Thus, the results demonstrated that pollution in Paranaguá bay induce liver damage in fish that inhabit this area.
Concentrations of metals in liver of Guiana dolphins (Sotalia guianensis) from an estuary in Southeast of Brazil
Authors: Salgado Lilian Dalago , Mas Rosa Suzana , Azevedo Júlio César Rodrigues de
Published: August 2018

Concentrations of Fe, Zn, Cu, Mn, Pb, Cr, Co and Ni were measured in the liver of 21 Guiana dolphins from the Estuarine-Lagoon Complex of Iguape-Cananéia, in order to indicate the impact of their habitat and to verify if these concentrations differ between the sexes and age classes. The concentrations followed the order: Fe>Zn>Cu>Mn>Pb>Cr>Co>Ni, and with the exception of lead, all concentrations were in the same order of magnitude observed for the species. The accumulations between the sexes were similar, while copper were higher in infants, suggesting that the organ can act as a reservoir for Co in a period of rapidly postnatal growth. Lead mean concentration (3.17 μg g-1) were the highest described for the species, which from a toxicological point of view may be a matter of concern. This accumulation suggests a trophic transfer, indicating the contamination of the food chain, which possibly reflects the local environmental contamination caused by ancient lead mining.
Genetic Diversity Analysis of the Natural Populations of Mediterranean Mussels [Mytilus galloprovincialis (Lmk.)] in Agadir Bay: Assessment of the Molecular Polymorphism and Environmental Impact
Authors: Korrida Amal , Jamil Jadallah Sami , Izaabel Hassan , Benhissoune Said
Published: August 2018

Mediterranean mussel (Mytilus galloprovincialis Lmk) has a great environmental and economic importance for Morocco. This work studies the genetic structure and impact of chemical pollution on three different marine populations of Mytilus galloprovincialis that live within Agadir bay. Three collections were made at two clean sites (Cape Ghir and Cape Aglou) and at an impacted site exposed to intense boating and industrial activities (Anza). A 300-bp portion of the mitochondrial DNA coding-region Cytochrome C Oxidase subunit 1 (COI) was studied by polymerase chain reaction (PCR) and DNA sequencing reactions to assess and evaluate amounts of polymorphism in each site. Genetic analysis using COI for 64 individuals showed no significant differentiation between the three subpopulations. AMOVA demonstrated that only 2.83% of variation exists between populations. Besides the genetic evidence presented herein, mussel’s adaptation mechanisms and strategies to marine pollution are also discussed.
Risk Factors Affecting the Phenotypic Expression of Heterozygous Familial Hypercholesterolemia in Pakistani Population

Published: August 2018

Familial hypercholesterolemia (FH) is a genetic disorder of lipoprotein metabolism recognized by high plasma concentrations of low-density lipoprotein cholesterol (LDL-C), tendon xanthomas, and high risk of early coronary heart disease. The phenotypic expression of FH is variable and several genetic and other risk factors contribute to such variability in clinical expression of the disease. FH is an autosomal disorder characterized by increased levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and tendinous xanthmata (TX). Clinical phenotype of FH has previously been shown to be associated with increased coronary heart disease (CHD) and premature death. The present study was carried out in a Pakistani population to examine the contribution of environmental factors on the expression of this disease. A detailed examination of the physical and biochemical features of the FH was performed in a cohort of 335 individuals (202 males, 133 females) from Pakistan. Our results indicate that Pakistani females with FH had high levels of TC and LDL-C as compared to Pakistani males. Overall the concentrations of high density lipoprotein cholesterol (HDL-C) were significantly lower for both sexes as compared to the controls (normal). We have also found that high cholesterol levels were associated with increased incidence of CHD in FH Pakistani population where both male and female individuals showed 69% and 31% CHD, respectively. The mean onset age for coronary symptoms was about 38 years in males as compared to 45 years in females. A greater risk of developing CHD has been linked with levels of TC along with a history of smoking in males and presence of hypertension (HTN) in females. Our results indicate that these risk factors possibly affect and contribute in the phenotypic expression of FH in Pakistani population.

Published: August 2018

During March 2009 in the public gardens and the University of Sciences of Kenitra city (Morocco), 60% of leaves of 100 plants of pomegranate (Punica granatum L. ’Nana’) presented foliar lesions that affecting the aesthetic appearance of this ornamental plant. Bipolaris spicifera was isolated from ten necrotic lesions of 25 leaves. The artificial inoculation of the healthy leaves of three plants of Punica granatum L. ’Nana’ by conidial suspension of the pathogen induced the same lesions to that observed in nature. The diseased foliar surface and the total number of diseased leaves 30 days after inoculation with B. spicifera conidial suspension were 37.5% and 78. Conidia production of B. spicifera on inoculated leaves was 0.81 x 105 spore cm-2 and the fungus was re-isolated from lesions on inoculated plants. This is the first report of B. spicifera on pomegranate in Morocco.

In addition to other environmental factors, such lichen species encountered are involved in one way or another in the deterioration of building materials of the Hassan Tower.
Review of the Rpt3 Genes Encoding Part of the 26S Proteasome Associated with Loci Underlying Disease Resistance in Soybean
Authors: Malik Shivani , Bhaumik Sukesh , Lightfoot David A.
Published: August 2018

The 26S proteasomal complex is a multifunctional proteolytic machinery of the cell. The proteasome plays role in myriad of cellular functions, which have been further diversified by its separable proteolytic and non-proteolytic sub-complexes. Protein quality control and turnover, cell cycle regulation, gene regulation and DNA repair are among the key processes controlled by the proteasome. Disease resistance in plants invokes changes in all the processes controlled by the 26S proteasome. In this review, the potential contribution of genes encoding the proteasome to disease resistance in soybean (Glycine max L. Merr.) was examined.

Abstract. Transport of anthropogenic aerosol into the Arctic in the spring
months has the potential to affect regional climate; however, modeling
estimates of the aerosol direct radiative effect (DRE) are sensitive to
uncertainties in the mixing state of black carbon (BC). A common approach in
previous modeling studies is to assume an entirely external mixture (all
primarily scattering species are in separate particles from BC) or internal
mixture (all primarily scattering species are mixed in the same particles as
BC). To provide constraints on the size-resolved mixing state of BC, we use
airborne single-particle soot photometer (SP2) and ultrahigh-sensitivity
aerosol spectrometer (UHSAS) measurements from the Alfred Wegener Institute
(AWI) Polar 6 flights from the NETCARE/PAMARCMIP2015 campaign to estimate
coating thickness as a function of refractory BC (rBC) core diameter and
the fraction of particles containing rBC in the springtime Canadian high
Arctic. For rBC core diameters in the range of 140 to 220 nm, we find
average coating thicknesses of approximately 45 to 40 nm, respectively,
resulting in ratios of total particle diameter to rBC core diameters ranging
from 1.6 to 1.4. For total particle diameters ranging from 175 to 730 nm,
rBC-containing particle number fractions range from 16 % to 3 %,
respectively. We combine the observed mixing-state constraints with simulated
size-resolved aerosol mass and number distributions from GEOS-Chem–TOMAS to
estimate the DRE with observed bounds on mixing state as opposed to assuming
an entirely external or internal mixture. We find that the pan-Arctic average
springtime DRE ranges from −1.65 to −1.34 W m−2 when assuming
entirely externally or internally mixed BC. This range in DRE is reduced by
over a factor of 2 (−1.59 to −1.45 W m−2) when using the
observed mixing-state constraints. The difference in DRE between the two
observed mixing-state constraints is due to an underestimation of BC mass
fraction in the springtime Arctic in GEOS-Chem–TOMAS compared to Polar 6
observations. Measurements of mixing state provide important constraints for
model estimates of DRE.
Primary and secondary organic aerosol from heated cooking oil emissions
Authors: Liu Tengyu , Wang Zhaoyi , Wang Xinming , Chan Chak K.
Published: August 2018

Abstract. Cooking emissions have been identified as a source of both primary organic
aerosol (POA) and secondary organic aerosol (SOA). To examine the
characteristics of SOA from cooking emissions, emissions from seven vegetable
oils (sunflower, olive, peanut, corn, canola, soybean, and palm
oils) heated at 200 ∘C were photooxidized under high-NOx
conditions in a smog chamber. OA was characterized using a high-resolution
time-of-flight aerosol mass spectrometer (HR-TOF-AMS). Sunflower, peanut,
corn, canola, and soybean oil generated relatively low concentrations of POA
(≤0.5 µg m−3) in the chamber. For palm and olive oil,
positive matrix factorization (PMF) analysis separated POA and SOA better
than the residual spectrum method. Temporal trends in concentrations of POA
from heated palm oil were accurately predicted assuming first-order POA wall
loss. However, this assumption overestimated POA concentrations from heated
olive oil, which was attributed to the heterogeneous oxidation of POA. The
mass spectra of the PMF resolved POA factor for palm oil, and the average POA
from sunflower, peanut, corn, and canola oils were in better agreement
(θ=8–12∘) with ambient cooking organic aerosol
(COA) factors resolved in select Chinese megacities than those found in given
European cities in the literature. The mass spectra of SOA formed from heated
cooking oils had high abundances of m∕zs 27, 28, 29, 39, 41, 44, and 55 and
displayed limited similarity (θ > 20∘) with
ambient semi-volatile oxygenated OA (SV-OOA) factors. The entire OA data set
measured herein follows a linear trend with a slope of approximately −0.4 in
the Van Krevelen diagram, which may indicate oxidation mechanisms involving
the addition of both carboxylic acid and alcohol or peroxide functional groups
without fragmentation and/or the addition of carboxylic acid functional
groups with fragmentation.
Transport of Canadian forest fire smoke over the UK as observed by lidar

Published: August 2018

Abstract. Layers of aerosol at heights between 2 and 11 km were observed with Raman
lidars in the UK between 23 and 31 May 2016. A network of these lidars,
supported by ceilometer observations, is used to map the extent of the
aerosol and its optical properties. Space-borne lidar profiles show that the
aerosol originated from forest fires over western Canada around 17 May, and
indeed the aerosol properties – weak volume depolarisation (<5 %) and a
lidar ratio at 355 nm in the range 35–65 sr – were consistent with
long-range transport of forest fire smoke. The event was unusual in its
persistence – the smoke plume was drawn into an atmospheric block that kept
it above north-western Europe for 9 days. Lidar observations show how the
smoke layers became optically thinner during this period, but the lidar ratio
and aerosol depolarisation showed little change. The results demonstrate the
value of a dense network of observations for tracking forest fire smoke, and
show how the dispersion of smoke in the free troposphere leads to the
emergence of discrete thin layers in the far field. They also show how
atmospheric blocking can keep a smoke plume in the same geographic area for
over a week.
A stochastic model for the hourly solar radiation process for application in renewable resources management
Authors: Koudouris Giannis , Dimitriadis Panayiotis , Iliopoulou Theano , Mamassis Nikos , Koutsoyiannis Demetris
Published: August 2018

Abstract. Since the beginning of the 21st century, the scientific
community has made huge leaps to exploit renewable energy sources, with solar
radiation being one of the most important. However, the variability of solar
radiation has a significant impact on solar energy conversion systems, such
as in photovoltaic systems, characterized by a fast and non-linear response
to incident solar radiation. The performance prediction of these systems is
typically based on hourly or daily data because those are usually available
at these time scales. The aim of this work is to investigate the stochastic
nature and time evolution of the solar radiation process for daily and hourly
scale, with the ultimate goal of creating a new cyclostationary stochastic
model capable of reproducing the dependence structure and the marginal
distribution of hourly solar radiation via the clearness index KT.

Abstract. The Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA)
was operated on board the German High Altitude and Long Range Research
Aircraft (HALO) during the PGS (POLSTRACC/GW-LCYCLE/SALSA) aircraft campaigns
in the Arctic winter 2015/2016. Research flights were conducted from 17
December 2015 until 18 March 2016 within 25–87∘ N,
80∘ W–30∘ E. From the GLORIA infrared limb-emission
measurements, two-dimensional cross sections of temperature, HNO3,
O3, ClONO2, H2O and CFC-12 are retrieved. During 15
scientific flights of the PGS campaigns the GLORIA instrument measured
more than 15 000 atmospheric profiles at high spectral resolution. Dependent on flight altitude and
tropospheric cloud cover, the profiles retrieved from the measurements typically range between 5 and
14 km, and vertical resolutions between 400 and 1000 m are achieved. The estimated total (random and
systematic) 1σ errors are in the range of 1 to 2 K for temperature and 10 % to 20 % relative
error for the discussed trace gases. Comparisons to in situ instruments deployed on board HALO have been
performed. Over all flights of this campaign the median differences and median absolute deviations between
in situ and GLORIA observations are -0.75K±0.88 K for temperature, -0.03ppbv±0.85 ppbv for
HNO3, -3.5ppbv±116.8 ppbv for O3, -15.4pptv±102.8 pptv for ClONO2, -0.13ppmv±0.63 ppmv for H2O and -19.8pptv±46.9 pptv for CFC-12. Seventy-three percent of these differences are
within twice the combined estimated errors of the cross-compared instruments.
Events with larger deviations are explained by atmospheric variability and
different sampling characteristics of the instruments. Additionally,
comparisons of GLORIA HNO3 and O3 with measurements of the
Aura Microwave Limb Sounder (MLS) instrument show highly consistent
structures in trace gas distributions and illustrate the potential of the
high-spectral-resolution limb-imaging GLORIA observations for resolving
narrow mesoscale structures in the upper troposphere and lower stratosphere
(UTLS).

Abstract. In this work we present evidence that quasi cyclical perturbations in total ozone (Quasi Biennial Oscillation (QBO), El Nino Southern Oscillation (ENSO) and North Atlantic Oscillation (NAO)) can be used as independent proxies in validating Global Ozone Monitoring Experiment-2 aboard MetopA (GOME-2A) satellite total ozone data, using ground-based measurements, other satellite data and chemical transport model calculations. The analysis is performed in the frame of the validation strategy on longer time scales within the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), Satellite Application Facility on Atmospheric Composition Monitoring (AC SAF) project, and covers the period 2007–2016. In general, we find that GOME-2A total ozone data depict the QBO/ENSO/NAO natural fluctuations in concurrence with co-located Solar Backscatter Ultraviolet Radiometer (SBUV), GOME-type Total Ozone Essential Climate Variable (GTO-ECV) and ground-based (GB) observations. Total ozone from GOME-2A is well correlated with the QBO (highest correlation in the tropics of +0.8) in agreement with SBUV, GTO-ECV and GB data which also give the highest correlation in the tropics. The differences between deseazonalised GOME-2A and GB total ozone in the tropics are within ±1 %. These differences were tested further as to their correlations with the QBO. The differences had practically no QBO signal, providing an independent test of the stability of the long-term variability of the satellite data. Correlations between GOME-2A total ozone and the Southern Oscillation Index (SOI) were studied over the tropical Pacific Ocean after removing seasonal and QBO related variability. Correlations between ozone and SOI are the order of +0.6, in consistency with SBUV and GB observations. Differences between GOME-2A and GB measurements at the station of Samoa (American Samoa; 14.25° S, 170.6° W) are within ±1.5 %. We also studied the impact of NAO on total ozone in the northern mid-latitudes in winter. We find very good agreement between GOME-2A and GB observations over Canada and Europe as to their NAO-related variability, with mean differences reaching the ±1 % levels. The agreement and small differences which were found between the independently produced total ozone data sets as to the influence of QBO, ENSO and NAO show the importance of these climatological proxies as additional tool for monitoring the long-term stability of satellite-ground truth biases.
Tectono-thermal evolution of Oman's Mesozoic passive
continental margin under the obducting Semail Ophiolite: a
case study Jebel Akhdar, Oman

Published: August 2018

Abstract. The Mesozoic sequences of the Oman Mountains experienced only weak post-obduction overprint and deformation, thus they offer a unique natural laboratory to study obduction. We present a study of the pressure and temperature evolution in the passive continental margin under the Oman Ophiolite, using numerical basin models calibrated with thermal maturity data, fluid inclusion thermometry and low-temperature thermochronology. Thermal maturity data from the Adam Foothills constrain burial in the foredeep moving in front of the advancing nappes to be at least 4 km. Peak temperature evolution in the carbonate platform under the ophiolite is only weakly dependent on the temperature of the overriding nappes which have cooled during transport from the oceanic subduction zone to emplacement. Fluid-inclusion thermometry yields pressure-corrected homogenization temperatures of 225 to 266 °C for veins formed during progressing burial, 296–364 °C for veins related to peak burial and 184 to 213 °C for veins associated with late-stage strike-slip faulting. In contrast, the overlying Hawasina nappes have not been heated above c. 170 ºC, as witnessed by only partial resetting of the zircon (U-Th)/He thermochronometer. In combination with independently determined temperatures from solid bitumen reflectance, we infer that the fluid inclusions of peak-burial-related veins formed at minimum pressures of 225–285 MPa. This implies that the rocks of the future Jebel Akhdar Dome were buried under 8–10 km of ophiolite on top of 2 km of sedimentary nappes, which is in agreement with thermal maturity data of solid bitumen reflectance and Raman spectroscopy. Burial of the passive margin under the ophiolite results in sub-lithostatic pore pressures, in agreement with observations on veins formed in dilatant fractures in the carbonates. We infer that overpressure is induced by rapid burial under the ophiolite nappes. Obduction-related tilt of the passive margin in combination with overpressure in the passive margin caused fluid migration towards the south in front of the nappes. Exhumation of the Jebel Akhdar as indicated by our zircon (U-Th)/He data, integrated with existing data, started as early as the late Cretaceous to early Cenozoic, linked with extension along a major listric shear zone with top-to-NNE shear sense, together with an early phase of extensional dome formation. The carbonate platform and obducted nappes of the whole Jebel Akhdar cooled together below c. 170 °C between 50 and 40 Ma, before the final stage of anticline formation.
Estimation of Arctic land-fast ice cover based on dual-polarized Sentinel-1 SAR imagery
Authors: Karvonen Juha
Published: August 2018

Abstract. Here a method for estimating the land-fast ice (LFI) extent from
dual-polarized Sentinel-1 SAR mosaics of an Arctic study area over the Kara
and Barents seas is presented. The method is based on temporal
cross-correlation between adjacent daily SAR mosaics. The results are
compared to the LFI of the Russian Arctic and Antarctic Research Institute
(AARI) ice charts. Two versions of the method were studied: in the first
version (FMI-A) the overall performance was optimized, and in the second
version (FMI-B) the target was a low LFI misdetection rate. FMI-A detected
over 73 % of the AARI ice chart LFI, and FMI-B a little over 50 % of
the AARI ice chart LFI. During the winter months the detection rates were
higher than during the melt-down season for both the studied algorithm
versions. An LFI time series covering the time period from October 2015 to
the end of August 2017 computed using the proposed methodology is provided on
the FMI ftp server. The time series will be extended twice annually.
Nuclear War in the Rivalry Phase of the Modern World-System
Authors: Denemark Robert A.
Published: August 2018

Large-scale war is a world-system phenomenon of the rivalry phase. Such conflicts have once again become a concern, and nuclear weapons make these prospects especially dangerous. This is particularly problematic since several world-systems perspectives suggest the chances for war will be greatest in the period from 2030 to 2050. I review the logic of rivalry, the reasons for the endurance of nuclear weapons, old and new nuclear strategies, and the processes that may pose the greatest existential dangers. Chase-Dunn and Podobnik (1995) identified processes that militate both in favor of and in opposition to nuclear war, and I pay particular attention to the way in which world-systems developments that increase the likelihood of major war have persisted, while those that retard the chances for major war have diminished. These dangers suggest that it may be time to turn some of our attention to the dynamics of systemic war and nuclear weapons.

Gendering the New Right-wing Populisms: A Research Note
Authors: Moghadam Valentine M.
Published: August 2018

Populism has become the subject of a large and growing literature but little is written about non-Western movements, and feminist scholars have yet to grapple with its gender dynamics, including its appeal to many women voters, and its gendered social consequences. In this research note, I briefly survey the literature and show how right-wing populist nationalism – a reaction to the ills of neoliberal capitalist globalization – is also found in Islamist movements. I call for an inclusive, progressive agenda that can appeal to and mobilize those who have been left behind.

This paper examined tourism support services as indicators for socio-economic development of Uyo. The study investigate visitors arrivals in the seven selected tourism support services, the demographic characteristics of the sampled population types of employment and distribution and challenges encountered by staff  in the tourism support services in the study area. Questionnaire and checklist were the methods used in data collection such that the questionnaire were distributed to staff in the tourism support services so as to  captured the demographic  characteristics of the sampled population, challenges  encountered by staff in the industry and the checklist was used to obtained data such as types and  distribution of employment. The result from data obtained indicates that the tourism support services  in Uyo have significantly contributed to the socio-economic  development of Uyo as evidenced in the various types and distribution of employment in the study. This was also affirmed in the tested hypothesis which shows a significant variation in employment generation between indigenous and non-indigenous in the study area. The finding also indicate that the staff in the industry were faced with challenges which need urgent attention if the tourism support services must function effectively in the study area.
On Nature and the Tactility of the Senses in Blade Runner 2049
Authors: Payne Catherine , Pitsis Alexandra
Published: August 2018

We explore Blade Runner 2049 through a series of subtle filmic moments. These moments contribute to an implicit narrative about the role of the senses, particularly tactility, in the development of human consciousness. This is navigated through the trajectory of the main character, Los Angeles Police Department (LAPD) Agent K, from replicant to a state of open-ended awareness. K (Ryan Gosling) as an evolving entity goes from existing as a synthetic being to experiencing the fragility and volatility of “being human”; in doing so, he encounters barriers within a wider, all-encompassing nature. The film is linked to Nabokov’s Pale Fire, in which we identify pivotal moments in K’s consciousness that are aligned with poetic concepts in this text. We contend that Blade Runner 2049 is a form of metacinema and is structured as an interrupted game, a spatial journey composed of layers, ruptures, and bifurcations expressed through barriers. These concepts will be discussed in this article.
Borrelia miyamotoi infection rate in black-legged ticks (Ixodes scapularis) recovered from heads of hunter-harvested white-tailed deer (Odocoileus virginianus) in Pennsylvania: A public health perspective

Published: August 2018

Studies reporting tick infection rates for Borrelia miyamotoi, a zoonotic arthropod-borne pathogen responsible for Borrelia miyamotoi disease, in the Commonwealth of Pennsylvania are limited. To ascertain a statewide infection rate of B. miyamotoi, ticks were collected from heads of 9,912 hunter-harvested white-tailed deer (Odocoileus virginianus) presented to six regional Pennsylvania Game Commission Chronic Wasting Disease sampling stations in early December of 2013, 2014, and 2015. Of the 2973 ticks recovered, 1990 (66.9%) were identified as adult Ixodes scapularis. The 1990 I. scapularis ticks were grouped into 409 pools containing one to six ticks and PCR-tested for the presence of B. miyamotoi. The pooled samples had a statewide maximum likelihood estimation tick infection rate of 7.64/1000 (95% CI, 4.46–12.29) for B. miyamotoi, confirming a state-wide presence, and supporting the need for an increased public health awareness for this emerging zoonotic arthropod-borne pathogen.
