This article reports the concept of digital library (DL) with its definitions, concept, generic architecture, ethics and librarianship related to DL. DLs are created by Library professionals, publishers, Government initiatives, societies and other higher educational institutions. There are different types of files and file formats are created and stored on DL. For uploading the files, the copyright / IPR issues are involved. As one cannot upload directly someone's file without the permission of that person. In information communication technology (ICT) environment, the Internet and web enables everyone to have access to the e-contents available from anywhere at any time. Due to this, DL creators cannot take it granted to upload them and make them available online. The IPR issues in digital environment plays a key role for identifying and taking permissions from the respective authors / publishers / content creators to upload the digital content. DL and IPR issues are discussed with the digital rights issues.
Evaluating the Performance of e-Government in Egypt
Authors: Hussein Safaa Ahmed
Published: January 2018

This empirical article studies the performance of e-government in Egypt from the perspective of citizens within a public value based conceptual framework. This study adopts a theoretical model that integrates two streams of research: (i) the updated DeLone and McLean IS Success Model and (ii) Public Value and proposes a conceptual framework. The model is empirically tested and validated through structural equation modelling analysis. Democracy, reflexivity and productivity were found to be the three distinct value types desired as outcomes by citizens. Trust in e-Government mediated the relationship between the quality constructs and net benefits, whereas citizen satisfaction only mediated the relationship between information quality, system quality and net benefits and has no mediating effect on the relationship between service quality and net benefits.
Assessing different holding pen cooling systems through environmental variables and productivity of lactating cows
Authors: Silva Danilo Corrêa , Passini Roberta
Published: January 2018

This studyaimed to assess different holding pen climatization systems for dairy cattle through environmental variables, milk production and economic indexes. Sixteen lactating cows were used, distributed in a 4 x 4 Latin square design consisting of four groups of four animals, assessed in four periods, seven days each, and in four holding pen environments: SUN– external environment (in the sun), SHA– 80%-protection polypropylenemesh shading, SHA + SPR– 80% polypropylene mesh shading + water sprinkling, SHA + SPR + VEN – 80% polypropylene mesh shading + water sprinkling + ventilation. The animals remained for 30 minutes in their respective environments. In this period, environmental variables were collected using data loggers, and the milk produced, in kg, by each animal was subjected to the treatments. Fixed and variable costs were calculated for economic analysis. The SHA + SPR + VEN treatment presented itself as the best environment (p < 0.05), promoting an increase in the milk produced by the cows and in themonthly income, with 44 days for return on investment.

Published: January 2018

Enzymes can be an interesting additive in high energy diets for feedlot cattle. However, literature is inconsistent on this subject. Thus, this study was conducted to evaluate animal performance of feedlot bulls receiving high energy diet, composed of a mixture of 85% whole corn grain and 15% protein-mineral-vitamin nucleus, without or with xylanase included in the diets. Diets consisted of: CON - diet without enzymes (Control) and ENZ - diet with enzymes (5 g animal day-1). Thirty-two bulls were used, with an average age of 11 ± 2 months, average initial weight of 365 ± 5 kg, and finished for 119 days in feedlot. The experimental design was completely randomized, consisting of two treatments and eight replications, where each replication was represented by a stall with two animals. ENZ increased the weight gain (1.69 vs. 1.33 kg day-1) and improved the feed conversion (4.60 vs. 6.03 kg-1) in the adaptation period of the animals. Animals receiving ENZ increased 1.65% of carcass yield and were 7.57% more efficient in the conversion of dry matter consumed into carcass gain in relation to CON. Carcass traits of feedlot-finished bulls were not altered by inclusion of enzymes. Xylanase-complex could increase efficiency in feedlot bulls.

Published: January 2018

The environment is very important for the performance of laying hens; thus, techniques are required to improve production systems, providing better welfare for poultry and consequent increase in the quality of the final product, the egg. This study aimed to evaluate the effects of rearing system, on the floor and in cage, on the performance and egg internal and external quality of laying hens. A total of 320 Hysex Brown laying hens, with 34-43 weeks days of age, was distributed in a completely randomized design, with two treatments, floor and cage, with 10 replicates each. The parameters evaluated were: individual feed intake, egg production per replicate, feed conversion per dozen eggs, egg weight; weight and percentage participation of shell, albumen and yolk, specific gravity, body weight variation and viability of birds. The results show that the birds raised on the floor showed best results as to egg production, besides the best internal and external quality, with greater weight of egg, yolk, albumen, shell and with lower losses of eggs. Because of the negative effects of the cage system, in general, hens presented lower results when compared to results of those raised on the floor.

Published: January 2018

The present study aimed to assess the possible beneficial effects of the integration between bioflocs and periphyton to the Nile tilapia’s water quality and growth performance. There were four treatments with five replicates each: (1) Control: green waters, (2) Periphyton: substrate-based system, (3) BFT: bioflocs technology for aquaculture, and (4) Biophyton: integration between bioflocs and periphyton. Fish (1.63 ± 0.07 g) were reared for 10 weeks in twenty 250 L outdoor tanks. Two polyethylene boards were vertically set out in the Periphyton and Biophyton tanks as underwater substrates. The C: N ratios of water in the BFT and Biophyton tanks were adjusted to 15:1 with dry molasses applications. The concentrations of total ammonia nitrogen were higher in the Control and Periphyton tanks than in the BFT and Biophyton ones. On the other hand, the concentrations of reactive phosphorus were higher in the BFT and Biophyton tanks than in the Control and Periphyton ones. The fish final body weight, specific growth rate and fish yield have not differed between the tanks. The integration between bioflocs and periphyton has not brought clear benefits to tilapia culture on water quality and growth performance.
Endoplasmic Reticulum–Bound Transcription Factor CREBH Stimulates RANKL-Induced Osteoclastogenesis
Authors: Kim Jung Ha , Kim Kabsun , Kim Inyoung , Seong Semun , Nam Kwang-Il , Kim Kyung Keun , Kim Nacksung
Published: January 2018

Endoplasmic reticulum (ER) stress is triggered by various metabolic factors, such as cholesterol and proinflammatory cytokines. Recent studies have revealed that ER stress is closely related to skeletal disorders, such as osteoporosis. However, the precise mechanism by which ER stress regulates osteoclast differentiation has not been elucidated. In this study, we identified an ER-bound transcription factor, cAMP response element-binding protein H (CREBH), as a downstream effector of ER stress during RANKL-induced osteoclast differentiation. RANKL induced mild ER stress and the simultaneous accumulation of active nuclear CREBH (CREBH-N) in the nucleus during osteoclastogenesis. Overexpression of CREBH-N in osteoclast precursors enhanced RANKL-induced osteoclast formation through NFATc1 upregulation. Inhibiting ER stress using a specific inhibitor attenuated the expression of osteoclast-related genes and CREBH activation. In addition, inhibition of reactive oxygen species using N-acetylcysteine attenuated ER stress, expression of osteoclast-specific marker genes, and RANKL-induced CREBH activation. Furthermore, inhibition of ER stress and CREBH signaling pathways using an ER stress–specific inhibitor or CREBH small interfering RNAs prevented RANKL-induced bone destruction in vivo. Taken together, our results suggest that reactive oxygen species/ER stress signaling-dependent CREBH activation plays an important role in RANKL-induced osteoclastogenesis. Therefore, inactivation of ER stress and CREBH signaling pathways may represent a new treatment strategy for osteoporosis.
Mineral markers of porphyry copper mineralization: work in progress at the Gibraltar deposit, British Columbia
Authors: Plouffe A , Kobylinski C H , Hattori K , Wolfe L , Ferbey T
Published: January 2018

Indicator minerals that can persist within glacial sediments offer the potential to be tracers towards buried porphyry mineralization. This study is examining the composition of epidote, rutile and zircon in till and bedrock from the Gibraltar copper-molybdenum
porphyry deposit, British Columbia, to test their utility as indicators of mineralizing system fertility. Some rutile grains in till at Gibraltar have a composition comparable to rutile from the El Teniente porphyry copper deposit in Chile. Comparison of the composition of rutile in till and bedrock
at Gibraltar is in progress. Other studies have indicated that high Ce/Ce* values in magmatic zircon are indicative of oxidizing conditions that are favourable for the formation of porphyry deposits. At Gibraltar, zircon from the mineralized phase of the intrusion yields high Ce/Ce* values
(average of 133) relative to the barren intrusive phases. Epidote is more abundant in till in the region of the host intrusion. Such distribution was originally interpreted to be derived from the propylitic alteration related to porphyry mineralization. Detailed analysis of the epidote shows that
epidote in till could be derived from the contact zone between the Granite Mountain batholith and the Nicola volcanic rocks.
Geology of the Éléonore gold mine and adjacent gold showings, Superior Province, northern Quebec
Authors: Fontaine A , Dubé B , Malo M , McNicoll V J , Prud'homme N , Beausoleil C , Goutier J
Published: January 2018

Located in the northeastern part of the Superior Province, the Éléonore mine had mineral reserves of 4.57 Moz (23.44 Mt at 6.07 g/t Au), measured and indicated gold mineral resources of 0.93 Moz (5.14 Mt at 5.66 g/t Au) and inferred mineral resources of
2.35 Moz (9.73 Mt at 7.52 g/t Au). Predominantly hosted by metamorphosed and deformed turbiditic rocks of the La Grande subprovince, the deposit is located 1.5 km south of the tectonometamorphic boundary with the Opinaca subprovince. Subparallel ore zones composed an envelope with a width of 70 to
80 m and vertical extension of >1.4 km. Associated with potassic, boron- and calcium-rich alteration assemblages and Au-As-Sb-Bi -W metallic signature, gold mineralization is associated with disseminations of arsenopyrite, pyrrhotite and löllingite. Various mineralization styles
include veins and hydrothermal breccia, replacement zones, stockwork of quartz veins and veinlets composed of quartz, dravite, microcline, phlogopite, actinolite, diopside, hedenbergite, muscovite and schorl. Recent activities include field and underground mapping on the Éléonore,
Éléonore South and Cheechoo properties. Gold mineralization also occurs within the Cheechoo tonalite/granodiorite, pegmatites and paragneiss (Cheechoo and Moni prospects). At Cheechoo and Moni, gold mineralization is structurally-controlled and associated with the presence of
quartz-feldspar-(biotite-arsenopyrite-scheelite) sheeted veinlets in association with silicification albitization and 1 to 2% of arsenopyrite, pyrrhotite, pyrite and visible gold. This emerging gold district shares analogies with hypozonal orogenic gold deposits and reduced intrusion-related
gold systems and illustrates the potential of an area affected by a high metamorphic gradient near a subprovince boundary.
Gold along Cordilleran faults: Key characteristics and analogies between Phanerozoic and Archean settings
Authors: Castonguay S , Ootes L , Mercier-Langevin P , Devine F
Published: January 2018

Several gold deposits and prospects in the Canadian Cordillera of British Columbia and Yukon are associated, at least spatially, to major fault zones. The Llewellyn fault and Tally Ho shear zone region of northwestern British Columbia and southern Yukon is the
locus of a series of vein-hosted gold prospects and deposits, including the past-producing Engineer and Mount Skukum mines. Many of these gold occurrences have epithermal polymetallic signatures, although some are considered mesothermal-orogenic, as such related to first-order crustal breaks and
synchronous magmatism. However, the temporal and genetic relationships between the orogenic- and epithermal-style systems along the Llewellyn fault and Tally Ho shear zone remain to be clearly established. Reconnaissance work has underlined a three-part relationship between these large-scale
structures, gold mineralization and Eocene magmatic complexes. Characterization of Llewellyn fault zone in the Bennett Plateau and Tagish Lake area of British Columbia, and of the Tally Ho shear zone in the Tally Ho Mountain, Gold Hill and Mount Hodnett areas of Yukon, and of their spatially
associated gold mineralization, aims to test this model and ultimately draw comparisons with the much older, structurally controlled gold deposits of the Archean and Paleoproterozoic.

Published: January 2018

The Amaruq gold project is part of the Woodburn Lake group of the Rae Domain, in the western Churchill Province. Exploration for BIF-hosted gold deposits in this region has led to an emerging gold district, which comprises the Meliadine, Meadowbank and Amaruq
deposits. In the Amaruq area, the Woodburn Lake group comprises a 250 m thick Neoarchean volcano-sedimentary sequence intercalated with chert and silicate facies iron formations. The two main ore zones (i.e. Whale Tail and IVR) exhibit different ore and alterations styles related to distinct
geochemical and structural traps. The Whale Tail zone is primarily characterized by stratabound pyrrhotite-arsenopyrite-loellingite-gold replacement type mineralization in chert and iron formation. The ore zones at IVR consist of gold-bearing quartz-carbonate veins developed at, or near contacts
between favourable units or reverse fold fault zones. In both ore zones, the geometry and style of the ore are controlled by at least the two Paleoproterozoic phases of deformation, and crosscutting relationships between folded sedimentary rocks and quartz-carbonate veins indicate protracted
hydrothermal activity.
Breccia styles and controls on carbonate replacement-type ('Carlin-type') gold zones, Rackla belt, east-central Yukon

Published: January 2018

Drillhole logging of the three main Carlin-type prospects of eastern Rackla belt (north-central Yukon) demonstrates the diversity of ore styles and the frequent association of mineralization with several types of brecciated intervals formed through sedimentary,
hydrothermal and/or tectonic processes. This attests to the opportunistic nature of mineralizing fluids that exploit permeable pathways, regardless of their origin.

Authors: Tiwari Priya , Kumar Lalit , Singh Geetika , Seth Amlesh , Thulkar Sanjay
Published: January 2018

Background: The incidence of renal cell cancer (RCC) is increasing worldwide. However, scant information is available from the Indian subcontinent regarding its clinicopathological characteristics and survival outcomes. We retrospectively analyzed data of patients suffering from RCC at our center over the last one decade (2004–2013) to generate information on these aspects. Materials and Methods: Case records of 423 patients treated between 2004 and 2013 were retrospectively analyzed. Baseline characteristics, histopathological information, and survival outcomes were assessed. Overall survival was calculated from the time of diagnosis to death due to any cause. Results: The median age was 52 years (range: 18–87 years). Male: female ratio was 3.5:1. The median duration of symptoms was 3 months (range: 0–24 months). Thirty-five patients (8.3%) were detected in asymptomatic state. The most common symptom was hematuria (53.2%) followed by flank pain (46.3%). The most common histology was clear cell subtype (71.4%). Two hundred and ninety-three (69.3%) patients presented with nonmetastatic disease whereas 130 (30.7%) had upfront metastatic disease. Five-year survival in Stages 1, 2, 3, and 4 was 92.7%, 72.9%, 54.6%, and 11.5%, respectively. Conclusion: Younger age, higher male–female ratio, lower proportion of asymptomatic patients, higher proportion of advanced stage at diagnosis, and lower stage-wise survival were some of the key findings.

Published: January 2018

Background: Teratoma refers to neoplasm containing at least two germ cell layers derivatives foreign to the site of origin. Sacrococcygeal teratoma is most common congenital tumor commonly present as an exophytic mass of varying size at coccyx. Aims and Objectives: (1) The aim is to find age, sex, and clinical presentation of cases of sacrococcygeal teratoma. (2) Application of American Academy of Pediatrics' surgical section classification and histological grading in all cases. Materials and Methods: A retrospective, observational study was conducted in the Department of Pathology in collaboration with the Department of Pediatric Surgery from February 2009 to January 2014. A total 13 cases of sacrococcygeal teratoma were included in the present study. The records of these patients were reviewed, and clinical profiles were noted. An average 12 slides were examined in each case to evaluate histological type and grades. Results: A retrospective study was conducted including thirteen cases of histologically confirmed sacrococcygeal teratoma over 5 years period. Male to female ratio was 1:2. As per as age distribution is concerned, 3 neonates (23%) presented with sacrococcygeal mass. Associated congenital malformation was seen in 2 cases (15.4%). According to the American Academy of Pediatrics (Altman's) classification, 23% of cases were Type I, 31% of cases patients Type II, 31% of cases Type III and 15% were for Type IV. The significant presacral component was noted in all malignant tumors. Conclusion: Two clinical patterns were observed in sacrococcygeal teratoma related to the age of presentation. As sacrococcygeal teratoma has potential to become malignant, meticulous search for the malignant component is required for histopathological categorization.

Published: January 2018

The human epidermal growth factor receptor-2 (HER2)-targeted therapies have improved clinical outcomes for patients at any stage of HER2-positive breast cancer (BC). Trastuzumab, a monoclonal antibody that targets the HER2 receptor on BC cells, showed improved survival in metastatic BC (MBC). However, resistance to therapy arises in the majority of patients with advanced disease. Antibody–drug conjugate (ADC) is a relatively new development to deliver cytotoxic drugs specifically to cancer cells. Trastuzumab emtansine (T-DM1) is a HER2-targeted ADC, composed of trastuzumab, a stable thioether linker, and the potent cytotoxic agent, emtansine (DM1, derivative of maytansine). T-DM1 has been approved for use in patients with MBC who have failed prior therapy with trastuzumab and a taxane. Dose finding Phase I study established the maximum tolerated dose at 3.6 mg/kg every 3 weeks. Phase I and II studies of T-DM1 have shown clinical activity and a favorable safety profile in HER2-positive MBC patients. The Phase III randomized EMILIA and TR3RESA trials demonstrated that T-DM1 significantly improves progression-free and overall survival in pretreated HER2-positive MBC patients. Nausea and fatigue are most commonly reported adverse drug reactions with T-DM1 and cardiac toxicity comparable with standard of care therapies. The drug is well tolerated in most patients, with a predictable pharmacokinetic profile and minimal systemic exposure to free cytotoxic DM1. T-DM1 has emerged as an effective therapeutic option for the management of patients with HER2-positive MBC.

Published: January 2018

Longitudinally extensive transverse myelitis (LETM) is an unusual manifestation of systemic malignancy. It has been mainly reported with lung cancers and lymphoproliferative malignancy. LETM in systemic malignancy can be caused by either intramedullary metastases or paraneoplastic syndrome. Occurrence of LETM as the first manifestation of malignancy has been rarely reported. We present clinical, laboratory, and imaging findings of a 66-year-old man with nonsmall-cell lung (adeno) carcinoma, who presented with LETM without having any cardinal manifestations of lung malignancy. The rarity of the disease and especially such a presentation can cause considerable delay in the diagnosis and treatment.

Authors: Tragiannidis Athanasios , Apsemidou Athanasia , Liampas Ioannis , Koletsa Triantafyllia
Published: January 2018

Primary myelofibrosis (PMF) is a clonal disorder of a multipotent hematopoietic progenitor cell that occurs predominantly in the elderly age group. We report here an 11-year-old girl who presented with headache, fever, and splenomegaly. Full blood cell count revealed severe thrombocytosis. Laboratory and radiology examinations excluded the diagnosis of essential/reactive thrombocytosis. Bone marrow biopsy showed megakaryocytic hyperplasia, reticulin and collagen fibrosis, and erythroid and myeloid hypoplasia, findings compatible to PMF. The patient was put symptomatically on hydroxyurea and hydration due to thrombocytosis and platelet number decreased. Hematopoietic stem cell transplantation was scheduled to avoid delaying definitive therapy and secondary complications such as infections and transfusion dependency. To the best of our knowledge, this is the first reported case of PMF in childhood in Greece.

Published: January 2018

Introduction: There is a saying that “cancer cures smoking” as people often quit tobacco after diagnosis of cancer. Very few studies have analyzed the change in tobacco habits of a user after diagnosis of cancer in a relative or friend. Materials and Methods: In this cross-sectional study, 161 friends and relatives of 40 patients treated at Tata Memorial Hospital, Mumbai, India, were interviewed. They were given a questionnaire related to their tobacco habits. The results were analyzed statistically using Wilcoxon signed-rank test and Mann–Whitney test using SPSS. Results: Of the studied individuals, 114 were friends and 47 were blood relatives. 141 used smokeless tobacco, 18 were smokers, and 2 consumed tobacco in both the forms. The mean frequency of tobacco consumption among the friends and relatives before diagnosis of cancer was 12.24 per day and that at the time of interview was 9.76 per day. 35 persons (21.7%) stopped consumption whereas 19 (11.8%) reduced usage after diagnosis of cancer. The difference in mean consumption at median duration of 174 days is statistically significant (P = 0.0005). Conclusions: The diagnosis of tobacco-related cancer has significant impact on the tobacco consumption of friends and relatives. The abstinence rate is comparable to that of various tobacco deaddiction therapies in vogue.

o presente artigo tem por objetivo analisar a natureza do direito à informação como parte intrínseca e estruturante do direito de participação, a partir da consideração deste princípio como elemento fundamental para a promoção do desenvolvimento sustentável. Buscou-se também determinar o conteúdo da Convenção de Aarhus a partir de um marco normativo internacional que pretende efetivar a participação em questões ambientais a toda pessoa, física ou jurídica, pública ou privada, além de apresentar um caráter inovador no que tange às garantias de acesso à informação e participação em matéria ambiental. De forma a delimitar o alcance das medidas dispostas na referida Convenção, foi realizado estudo de caso relativo justamente à abrangência e interpretação que deve ser considerada pelos estados signatários no momento da aplicação do instrumento, tendo sido interposto perante o Tribunal de Justiça da União Europeia, dado que todos os estados-membros deste processo de integração tiveram que incorporar a Convenção como parte integrante do direito comunitário
De Hannah Arendt a Judith Butler: em busca da humanidade perdida nas fronteiras do Estado-nação
Authors: Wermuth Maiquel Angelo Dezordi , Nielsson Joice Graciele
Published: January 2018

O objetivo deste trabalho é refletir sobre a condição dos refugiados no mundo atual, a partir da obra de Hannah Arendt e Judith Butler. As reflexões de Arendt, ao fim da Segunda Guerra, feitas a partir da condição dos refugiados, excluídos das fronteiras estatais, resultaram em um alerta para a necessária desvinculação entre a proteção jurídico-política dos seres humanos, e sua vinculação, enquanto cidadãos, com determinado Estado-nação. Tal alerta conduziu a uma ruptura de conceitos tradicionais da filosofia política, como cidadania, Estados e direitos humanos, recepcionada e tida como impulsionadora da construção de um aparato jurídico-político de proteção dos direitos humanos em âmbito internacional, sem precedentes na história. Passados mais de setenta anos, novamente o refugiado coloca em cheque tal aparato, e o mundo continua a se mostrar incapaz de efetivar a proteção da vida humana de modo desvinculado da fronteira estatal. É neste sentido que Butler desenvolve seus estudos. Para a autora, as fronteiras (bio)políticas atuais continuam a cindir o mundo entre vidas abjetas e vidas que merecem ser vividas, embora agora não sejam apenas físicas, mas também simbólicas ou culturais e precisam ser, urgentemente, des-re-construídas performaticamente ou profanadas. A presente pesquisa utilizará o método fenomenológico-hermenêutico, a partir da constatação de que os sujeitos (autores do artigo) estão inseridos no mundo no qual os movimentos migratórios contemporâneos ocorrem, sendo direta e indiretamente afetados por eles, e justamente nesta intercessão, e não em alguma espécie de cisão, é que reside o significado do fenômeno.

Abstract. The number concentration of cloud particles is a key quantity for understanding aerosol-cloud interactions and describing clouds in climate and numerical weather prediction models. In contrast with recent advances for liquid clouds, few observational constraints exist on the ice crystal number concentration (Ni). This study investigates how combined lidar-radar measurements can be used to provide satellite estimates of Ni, using a methodology that constrains moments of a parameterized particle size distribution (PSD). The operational liDAR-raDAR (DARDAR) product serves as an existing base for this method, which focuses on ice clouds with temperatures Tc
IPA (V1): A framework for agent-based modelling of soil water movement
Authors: Mewes Benjamin , Schumann Andreas H.
Published: January 2018

Abstract. In the last decade, agent-based modelling (ABM) became a popular modelling technique in social sciences, medicine, biology and ecology. ABM was designed to simulate systems that are highly dynamic and sensitive to small variations in their composition and their state. As hydrological systems, and natural systems in general, often show dynamic and nonlinear behaviour, ABM can be an appropriate way to model these systems. Nevertheless, only few studies have utilized ABM method for process-based modelling in hydrology. The percolation of water through the unsaturated soil is highly responsive to the current state of the soil system, small variations in composition lead to major changes in the transport system. Hence, we present a new approach for modelling the movement of water through a soil column: autonomous water agents that transport water through the soil while interacting with their environment as well as with other agents under physical laws.

Abstract. Environment and Climate Change Canada’s online air quality forecasting model, GEMMACH, was extended to simulate atmospheric concentrations of benzene and seven polycyclic aromatic hydrocarbons (PAHs): phenanthrene, anthracene, fluoranthene, pyrene, benz(a)anthracene, chrysene, and benzo(a)pyrene (BaP). In the expanded model, benzene and PAHs are emitted from major point, area, and mobile sources, with emissions based on recent emission factors. Modelled PAHs undergo gas-particle partitioning (whereas benzene is only in the gas phase), atmospheric transport, oxidation, cloud processing, and dry and wet deposition. To represent PAH gas-particle partitioning, the Dachs-Eisenreich scheme was used, and we have improved gas-particle partitioning parameters based on an empirical analysis to get significantly better gas-particle partitioning results than the previous North American PAH model, AURAMS-PAH. Other added process parameterizations include the particle phase benzo(a)pyrene reaction with ozone via the Kwamena scheme and gas-phase scavenging of PAHs by snow via vapor sorption to the snow surface. The resulting GEM-MACH-PAH model was used to generate the first online model simulations of PAH emissions, transport, chemical transformation and deposition for a high resolution domain (2.5-km grid cell spacing) in North America, centered on the PAH-data-rich region of southern Ontario, Canada and the north-eastern United States. Model output for two seasons was compared to measurements from three monitoring networks spanning Canada and the U.S. Average summertime model results were found to be statistically indistinguishable from measurements of benzene and all seven PAHs. The same was true for the winter seasonal mean, except for BaP, which had a statistically significant positive bias.We present evidence that the benzo(a)pyrene results may be ameliorated via further improvements to PM and oxidant processes and transport. Our analysis focused on four key components to the prediction of atmospheric PAH levels: spatial variability; sensitivity to mobile emissions; gas-particle partitioning; and wet deposition. Spatial variability of PAHs/PM2.5 at 2.5-km resolution was found to be comparable to measurements. Predicted ambient surface concentrations of benzene and the PAHs were found to be critically dependent on mobile emission factors, indicating the mobile emissions sector has a significant influence on ambient PAH levels in the study region. PAH wet deposition was overestimated due to additive precipitation biases in the model and the measurements. Our overall performance evaluation suggests that GEM-MACHPAH can provide seasonal estimates for benzene and PAHs and be suitable for emissions scenario simulations.
The Utilization of Open Educational Resources in the Collaborative Learning Environment to Enhance the Critical Thinking Skill

Published: January 2018

Critical thinking as an outcome of learning is an essential issue in education. The application of the concept of Open Educational Resources or OER provides opportunities for students to obtain information more efficiently to support their learning. On the other hand, the collaborative learning is believed to be a robust pedagogical approach to build a good learning experience. This research describes and explores how the application of collaborative learning by using OER can enhance critical thinking skills. The method of this study was the pre-test and post-test one group design in physics lessons at secondary school students. Statistical analysis used paired t-test with an error of 5%. The teacher can measure the critical thinking skill by giving essay test. Scoring considered the process undertaken in problem-solving. The results of this study showed an increase in critical thinking skills significantly. This study also further discusses the implications associated with this research on learning physics.
Evaluation of evidence-based practice of catheter associated urinary tract infections prevention in a critical care setting: An integrative review
Authors: Henry Michelle
Published: January 2018

Background and objective: An estimated 449,300 catheter-associated tract urinary infection (CAUTI) incidents affecting Americans and 13,000 CAUTI-related deaths in the United States every year. The purpose of the review was the appraisal and integration of the best evidence practice for preventing CAUTI interventions and strategies to guide safety and quality initiatives in order to improve patient care.Methods: A total of 20 articles complied with the exclusion and inclusion criteria. The articles were studied, and the chosen articles were categorized in two areas of study: CAUTI prevention, and nurse education and knowledge improvement.Results: The articles selected were reviewed to encompass a review on the articles offering the most applicable corresponding information involving catheter-associated urinary tract infections and competency-based education.Conclusions: Analysis of the data from the literature search indicates the potential lack of compliance of CAUTI infection control practices is an issue for CAUTI problem. So implementing the best evidence to enforce CAUTI bundles compliance for CAUTI prevention is a key to reduce CAUTI rates.
On the Concept of Representations of Prime Numbers and Prime Products
Authors: Bissonnet Peter
Published: January 2018

The author used to think that the only representation of prime numbers, etc. was the prime number double helix representation. However, in 2011, the author published a paper which puzzled him and it eventually dawned upon him that there was more than one representation of prime numbers. The second representation will be referred to as the hyperbolic representation. The third representation will be called the parabolic representation and is related to the hyperbolic representation. The fourth representation is the triangular representation and is related to the hyperbolic representation. Both of the primary representations, the double helix and the hyperbolic both reject that 2 and 3 are prime numbers. The hyperbolic representation is shown to be related to Lorentz-like transformations.

Contemporary southeast asian reality is the result of numerous interactions between different ethnic groups and religions that have taken place throughout history. The nature of the region is also determined by the shape of the terrain and proximity of two civilizations: India and China. The article discusses the sources of civilizational and cultural diversity in Southeast Asia.
Fontenelle and Russia. Creation of the Petrine Myth in Eighteenth-Century France
Authors: Mosakowski Marek
Published: January 2018

In 1725 Fontenelle, a French writer, philosopher and member of the Académie des sciences, wrote Éloge du Czar Pierre Ier to commemorate the recent death of Peter the Great and at the same time to glorify the reforms undertaken by the late Russian Czar to modernize his country. By virtue of this text Fontenelle succeeded in creating the Petrine myth, subsequently popularized in France by other outstanding figures of the French Enlightenment infatuated with Russia, which in the course of the eighteenth century was undergoing unprecedented socio-political transformation. Our article aims to show how Fontenelle constructed this myth and what rhetorical devices he employed to advance and later to promote it in France of his times.
Strategia energetyczna Federacji Rosyjskiej wobec państw Grupy Wyszechradzkiej
Authors: Kłaczyński Robert
Published: January 2018

The Russian Federation is the big biggest petrol and natural gas exporter to the European petrol market. The V4 countries are a part of this market. They have various energy potential, various foreign policy making conceptions and finally they have different opinions about UE`s role on the European petrol market. What they share is dependency on the Russian Federation in the natural gas and petroleum import, and energy security concerns. All this together overlaps with Russian “energy hegemony” strategy aimed at using the natural resources as a tool to create foreign and domestic policies and influencing ongoing events in Europe. Thus a paper entitled “Russian Federation`s energy strategy towards Visegrad Group Countries” aims to characterize relations between Russian Federation and V4 Countries within the energy policies conducted by this international relations players.
Kwestia migracji w polityce współczesnej Austrii
Authors: Romejko Adam
Published: January 2018

Austria is a country that in politics is guided by pragmatism. The main determinant of what is politically correct or not, it is the national interest. This approach is revealed in the past and present, including the question of the migrant community. It does not matter whether we are dealing with economic or political migrants or refugees. Since the sixties Austria is becoming a popular country where newcomers sought a better life. Many guest workers came then from Turkey and Yugoslavia. On the one hand, the Austrian authorities legally regulated migration and offered access to employment, on the other hand they tried to avoid restrictions. This pragmatic approach was due to favourable economic conditions prevailing in Austria.
A similar situation we face today. The authorities want to control the influx of foreigners into Austria and at the same time without any restrictions they let in to the country people describing themselves as refugees. The presence of foreigners is an important part of the political game. Left-wing parties recognize that immigrants are important voters. Their representatives want in this way to gain popularity among Austrians who fear the negative impact of the influx of foreigners and promoted multiculturalism policy. A negative consequence of the Austrian pragmatism is highly critical assessment of the countries of Central and Eastern Europe, which do not support naive Germany’s policy in relation to the latest wave of newcomers. Austria, which in the past was seen as a bridge between the West and the East, has lost the support of the criticized countries, including Poland.
