Evidence for energetic particle precipitation and quasi-biennial oscillation modulations of the Antarctic NO2 springtime stratospheric column from OMI observations
Authors: Gordon Emily M. , Seppälä Annika , Tamminen Johanna
Published: June 2020

Abstract. Observations from the Ozone Monitoring Instrument (OMI) on the Aura satellite are used to study the effect of energetic particle precipitation (EPP, as proxied by the geomagnetic activity index, Ap) on the Antarctic stratospheric NO2 column in late winter–spring (August–December) during the period from 2005 to 2017. We show that the polar (60–90∘ S) stratospheric NO2 column is significantly correlated with EPP throughout the Antarctic spring, until the breakdown of the polar vortex in November. The strongest correlation takes place during years with the easterly phase of the quasi-biennial oscillation (QBO).
The QBO modulation may be a combination of different effects: the QBO is known to influence the amount of the primary NOx source (N2O) via transport from the Equator to the polar region; and the QBO phase also affects polar temperatures, which may provide a link to the amount of denitrification occurring in the polar vortex. We find some support for the latter in an analysis of temperature and HNO3 observations from the Microwave Limb Sounder (MLS, on Aura).
Our results suggest that once the background effect of the QBO is accounted for, the NOx produced by EPP significantly contributes to the stratospheric NO2 column at the time and altitudes when the ozone hole is present in the Antarctic stratosphere.
Based on our findings, and the known role of NOx as a catalyst for ozone loss, we propose that as chlorine activation continues to decrease in the Antarctic stratosphere, the total EPP-NOx needs be accounted for in predictions of Antarctic ozone recovery.
Assessment of global total column water vapor sounding using a spaceborne differential absorption radar
Authors: Millán Luis , Roy Richard , Lebsock Matthew
Published: June 2020

Abstract. The feasibility of using a differential absorption radar (DAR) to retrieve total column water vapor from space is investigated. DAR combines at least two radar tones near an absorption line, in this case a water vapor line, to measure humidity information from the differential absorption on and off the line. From a spaceborne platform, DAR can be used to retrieve total column water vapor by measuring the differential reflection from the Earth's Surface. We assess the expected precision, yield, and potential biases of retrieved total column water vapor values by applying an end-to-end radar instrument simulator to near-global weather analysis fields collocated with CloudSat measurements. The approach allows us to characterize the DAR performance across a globally representative dataset of atmospheric conditions including clouds and precipitation as well as different surface types. We assume a hypothetical spaceborne G-band radar with pulse compression orbiting the earth at 405 km with a 1 m antenna, equivalent to a footprint diameter of 850 m, and 500 m horizontal integration. The simulations include the scattering effects of rain, snow, as well as liquid and ice clouds, spectroscopic uncertainties, and uncertainties due to the initial assumed water vapor profile. Results indicate that, using two radar tones at 167 and 174.8 GHz with a transmit power of 20 W ensures that both pulses will reach the surface at least 70 % of the time in the tropics and more than 90 % of the time outside the tropics, and that total column water vapor can be retrieved with a precision better than 1.3 mm.
Role of atmospheric horizontal resolution in simulating
tropical and subtropical South American precipitation in
HadGEM3-GC31
Authors: Monerie Paul-Arthur , Chevuturi Amulya , Cook Peter , Klingaman Nick , Holloway Christopher E.
Published: June 2020

Abstract. We assess the effect of increasing horizontal resolution on simulated precipitation over South America in a climate model. We use atmosphere-only simulations, performed with HadGEM3-GC31 at three horizontal resolutions: N96 (~ 130 km, 1.88° × 1.25°), N216 (~ 60 km, 0.83° × 0.56°), and N512 (~25 km, 0.35° × 0.23°). We show that all simulations have systematic biases in annual mean and seasonal mean precipitation over South America (e.g. too wet over the Amazon and too dry in northeast). Increasing horizontal resolution improves simulated precipitation over the Andes and north-east Brazil. Over the Andes, improvements from horizontal resolution continue to ~ 25 km, while over north-east Brazil, there are no improvements beyond ~ 60 km resolution. These changes are primarily related to changes in atmospheric dynamics and moisture flux convergence. Over the Amazon basin, precipitation variability increases at higher resolution. We show that some spatial and temporal features of daily South American precipitation are improved at high resolution, including the intensity spectra of rainfall. Spatial scales of daily precipitation features are also better simulated, suggesting that higher resolution may improve the representation of South American mesoscale convective systems.
Effects of multi-scale heterogeneity on the simulated evolution of ice-rich permafrost lowlands under a warming climate
Authors: Nitzbon Jan , Langer Moritz , Martin Léo C. P. , Westermann Sebastian , Schneider von Deimling Thomas , Boike Julia
Published: June 2020

Abstract. Thawing of ice-rich permafrost deposits can cause the formation of thermokarst terrain, thereby involving ground subsidence and feedbacks to the thermal and hydrological regimes of the subsurface. Thermokarst activity can entail manifold pathways of landscape evolution and cause rapid permafrost thaw in response to a warming climate. Numerical models that realistically capture these degradation pathways and represent the involved feedback processes at different spatial scales, are required to assess the threats and risks that thermokarst processes pose to the functioning of ecosystems and human infrastructure in the Arctic. In this study, we therefore introduce a multi-scale tiling scheme to the CryoGrid 3 permafrost model which allows to represent the spatial heterogeneities of surface and subsurface conditions, together with lateral fluxes of heat, water, snow, and sediment, at spatial scales not resolved in Earth system models (ESMs). We applied the model setup to a lowland tundra landscape in northeast Siberia characterized by ice-wedge polygons at various degradation stages. We present numerical simulations under a climate-warming scenario and investigate the sensitivity of projected permafrost thaw to different terrain heterogeneities, on both a micro-scale (ice-wedge polygons) and a meso-scale (low-gradient slopes). We found that accounting for both micro- and meso-scale heterogeneities yields the most realistic possibilities for simulating landscape evolution. Simulations that ignored one or the other of these scales of heterogeneity were unable to represent all of the possible spatio-temporal feedbacks in ice-rich terrain. For example, we show that the melting of ice wedges in one part of the landscape can result in the drainage of other parts, where surface water has been impounded a number of decades earlier as a result of ice-wedge thermokarst. We also found that including subgrid-scale heterogeneities in the simulations resulted in a more gradual response in terms of ground subsidence and permafrost thaw, compared to the more abrupt changes in simple one-dimensional simulations. Our results suggest that, under a warming climate, the investigated area is more likely to experience widespread drainage of polygonal wetlands than the formation of new thaw lakes, which is in general agreement with evidence from previous field studies. We also discuss how the presented model framework is able to capture a broad range of processes involved in the cycles of ice-wedge and thaw-lake evolution. The results of this study improve our understanding of how micro- and meso-scale processes control the evolution of ice-rich permafrost landscapes. Furthermore, the methods that we have developed allow improved representation of subgrid-scale processes such as thermokarst in ESMs.

Upon an improvement in the quality of life, air-conditioning has generally been applied. Nevertheless, environmental and health issues related with the use of air-conditioning occurs more often. Therefore, this paper aims to theoretically assess the principles of sustainability to achieve sustainability for renewable smart air-conditioning. Not only with consideration to the geometry (i.e. system mechanisms and components), fuzzy logic control and proportional-integral-derivative that such studies drawn particular attention to, but with concerns to a matter which has been previously ignored. That is with consideration to the potential which the renewable-based options, advanced smart control technique and profitability measures of air-conditioning reinforces the three pillars of sustainability, and their sustainable indicators as context-specific transformations have, to not only eradicate indoor health effects, lower the levels of energy consumption and rate of carbon emissions, but to uncover the significance of and particular contribution renewables and smart control opportunities makes to the sustainability of the system. In meeting this aim and demonstrating the sustainability of the theoretical framework, this paper reveals renewable and smart control system as the fundamental key components of the air-conditioning as it promotes to reduce levels of energy consumption and lower carbon emissions, vis-à-vis establish a comfortable and healthy indoor environment as an exercise in the sustainable theoretical framework whose status as renewable smart air-conditioning not only tackle poor indoor air quality but also combat global warming and climate change.
Gender Differences in the Application of Linguistic Politeness Marker (Please) in Request: A Sociolinguistic Study Egyptians' Request to Microbus Drivers
Authors: Alahmad Tarek Hider Mohammad
Published: June 2020

Linguistic politeness is considered a vexed question amid scholars and researchers alike which still, up to the date, a disputed phenomenon in the discipline of linguistics. This paper reports on a study that examined the gender differences in the stereotypical assumption that women are more polite than men in the use of request by the application of the Linguistic politeness marker (please) by Egyptians (Egypt, Mansours city). In the literature of linguistic politeness, the are many pioneers in the area as Culpeper et al. (2019) says that Maria Sifianou has enriched politeness research and pragmatics, viz. the inspection of the relationship amid universality and politeness. Furthermore, Leech (2014, p. 162) ,in The Pragmatics of Politeness, points out three different degrees of politeness from semantic sight in the account of the linguistic politeness marker "please" (a) Politeness marker (b) Illocutionary marker and (c) Information question marker. However, the linguistic politeness marker "please" is used to be uttered in requests as a general term to mitigate or soften the directive force of the speech event to addressee. Researchers and scholars who address the speech event request have spent considerable effort in classifying the variety of strategies for requesting in Anglophone. Moreover, Brown and Levinson’s model (1987, p. 68–9) proposed five “superstrategies” for doing FTAs, of which requests were a paradigm case. In this study, the data were collected from the Egyptians riders who were going to their destinations in Mansoura city, Egypt. There are two groups (a) women (100) and (b) men (100). The participants are speaking in the local vernacular Arabic (Egyptian dialect). They came from random social background. Further, there are a table and a chart to illustrate the gender differences amid the two groups of women and men.

Published: June 2020

Because of climatic problems in the Brazilian semi-arid region, it is of fundamental importance to seek a culture that considers water scarcity and available natural resources. Thus, a randomized block design, with subdivided plots and six replications, was carried out in the experimental area of the treatment and wastewater reuse station of the Milagres Settlement, Apodi, Brazil, with the objective of evaluating cultivation of herbaceous cotton (Gossipyum hirsutum) fertigated with domestic sewage treated in a semi-arid environment. Two cultivation cycles were carried out, and the cotton plants were fed with three different solutions containing treated domestic sewage (TDE) plus supply water (PSW), to supply the crop evapotranspiration (ETc) (100% PSW – control, 50% PSW + 50% TDE and 100% TDE), with and without phosphate fertilization in pre-planting. The contribution of nutrients to the soil and plant growth were analyzed. The results indicated that the wastewater presents potential fertilizer, reaching to the soil amounts of some nutrients exceeding the cotton’s needs, when 100% of the ETc was supplied via fertigation with domestic effluent, resulting in an increase in the growth rates of the plants. There was no interaction between the percentages of wastewater and phosphate fertilization in pre-planting. Phosphorus alone promoted significant variation only in the first cycle, indicating that there is a residual fertigation effect with domestic effluent on the nutrient supply.

This study aimed to estimate plastochron, leaf area, and yield of Physalis peruviana seedlings grown in different environments and transplanted on different dates. The experiment was carried out in a completely randomized design, arranged in a 2 x 3 factorial scheme, namely: two cultivation environments (protected and field) and three transplanting dates (10/27/2013, 12/15/2013, and 02/11/2014). Four replicates of eight plants were used per plot, and the four central plants composed the useful area. Based on mathematical models and temperature data, plastochron was estimated for the entire crop cycle and vegetative and reproductive phases separately. Leaf area and node number were measured, and their relationship established at the end of the study. Other variables assessed were fruit number, mass, and yield per plant. Our results showed that the higher temperatures in the protected environment anticipated phenological timings. Plastochron values of 60.0 and 16.5 °C day-1 can be used during vegetative and reproductive stages, respectively. The protected environment increased vegetative growth and development, as well as yield of P. peruviana seedlings. In the Guarapuava-PR region, P. peruviana seedlings should be transplanted during the spring so that higher fruit yield and quality could be achieved.

Published: June 2020

The objectives of this study were to evaluate the accuracy of thoracic radiology as a screening test for congenital heart diseases in dogs, to identify the main contributions and limitations of this modality, and to verify the reproducibility of the evaluations by three observers with different levels of training. An interobserver, observational, retrospective and prospective study was carried out, including ninety dogs: thirty healthy animals, thirty with acquired heart diseases and thirty with congenital heart diseases, which all had thoracic radiographs and a confirmed echocardiographic diagnosis. The cases were separated and randomized by a mediator who did not participate in the reading of the radiographic examinations, and no evaluator had access to the patients' data. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of each observer were calculated in relation to the correct classification of dogs to groups of normal or acquired and congenital heart diseases, as well as identification of enlargement of the cardiac silhouette and large vessels of dogs with congenital heart diseases. Finally, the Kappa coefficient was obtained between the observers to verify the reproducibility of the radiological evaluations performed. In general, sensitivity, PPV and accuracy were unsatisfactory ( 70%), and the agreement ranged from poor to reasonable (between 0 and 0.39). Although greater accuracy was achieved in the differentiation of healthy dogs from those with acquired and congenital heart diseases by thoracic radiography, when compared to the other studies, the modality was able only to identify healthy patients, and could not differentiate the individuals with different forms of heart disease or define the cardiac malformations. In addition, there was low reproducibility between observers, therefore, this technique should not be used as a sole screening method in dogs with suspected congenital heart diseases.

Published: June 2020

The aim of this study was to evaluate the morphology and superoxide dismutase enzyme (SOD) activity of bovine preantral follicles (PFs) preserved in TCM 199, saline solution or PBS at different conservation periods. Cow ovaries (n=6) were divided into 7 fragments. One small piece of each ovarian fragment was randomly removed to evaluate SOD activity, while the remainder was immediately fixed for morphological evaluation as a control group. The other 6 fragments were randomly distributed in tubes containing TCM 199, saline solution, or PBS and maintained at 4ºC for 6 or 24 h. For histological evaluation, the fragments were fixed in Carnoy and stained with PAS-hematoxylin, following being classified PFs in relation to their follicular morphology in normal or degenerated. Determination of SOD activity was based on the ability to inhibit autoxidation of adrenaline in adrenochrome. Evaluation of follicular morphology showed that follicles preserved in TCM 199 for 6 h did not differ from the control (P > 0.05). In contrast, preservation in saline solution and PBS for 6 or 24 h and TCM 199 for 24 h decreased normal PFs compared to the control (P < 0.05). SOD showed a lower activity in ovarian cortical tissue kept in TCM 199 for 6 h and saline solution for 24 h than in the other groups. Our study shows that incubation using TCM 199 at 4°C for 6 h can be used to efficiently conserve female bovine PFs in situ.

Published: June 2020

The aim of this study was to evaluate the ruminal fermentation and degradation parameters, the kinetic flow of digesta in the gastrointestinal tract, and the milk fatty acid (FA) profile in Holstein x Gyr cows fed 59% sugarcane silage-based diets with 0% (control), 5%, 10% and 15% whole cottonseed (WCS) on a dry matter (DM) basis. Four rumen-cannulated cows with an average milk yield of 14.4±3.3 kg day-1 and 85±25 days in milk were allocated in a 4 x 4 Latin square design. There was no effect of dietary WCS levels on the intake of organic matter (OM), crude protein (CP), neutral detergent fiber (NDF) and nonfibrous carbohydrates, but there was a linear increase in the intake of ether extract (EE). There was no treatment effect on the apparent digestibility of DM, OM, CP, EE and NDF or on the ruminal degradability parameters for DM and NDF of sugarcane silage. Also, no treatment effects were observed on rumen pH, ruminal and postruminal particulate passage rates or on the rate of passage of the fluids in the rumen. WCS promoted linear reductions in the milk fat contents of lauric, myristic and palmitic acids and linear increases in the milk fat contents of stearic, oleic, trans-10 C18:1 and elaidic acids. The milk fat contents of vaccenic, rumenic, linoleic and ?-linolenic acids were unaffected by WCS supplementation. The inclusion of up to 15% WCS in sugarcane silage-based diets did not alter the digestibility of nutrients, the rumen degradability of the fiber, or the kinetic flow of digesta in the gastrointestinal tract of Holstein x Gyr cows but improved the nutritional quality of milk fat through an increase in the content of oleic acid, which is beneficial to human health, and decreased levels of hypercholesterolemic lauric, myristic and palmitic acids.

Published: June 2020

The objective of this study was to evaluate the use of a combination of essential oils, prebiotics and antibiotics on broiler production. The treatments consisted of a normal diet meeting the nutritional requirements, and diets with a 5% reduction of nutritional requirements, supplemented or not with antibiotics (En+Sal) (10 g ton-1 enramycin and 125 g ton-1 salinomycin) or a blend of essential oils (EOFOS) (oregano, anise and lemon) plus fructooligosaccharides (125 g ton-1). A total of 1,152 male one-day-old broilers were randomized by weight and distributed into a 2*3 factorial design, consisting of six treatments with each treatment containing eight replicates of 24 birds per experimental unit. The Student-Newman-Keuls test was performed at 5% probability. Broiler performance was evaluated at 10, 21 and 42 days, intestinal morphometry was evaluated at 21 days, microbiological cecum counts at 33 days, blood parameters at 35 days and carcass and cuts yield at 42 days of age. Broilers fed reduced diets had a reduction in performance (P < 0.05). There was an interaction (P < 0.05) between diet type and prebiotics for jejunum villus height and villus height:crypt depth ratios for all intestinal segments. There was no effect (P > 0.05) of growth promoters and diet type on the Lactobacillus and Bifidobacterium populations within the gastrointestinal tract. There were no differences for duodenum or ileum villus heights (P > 0.05). Broilers fed EOFOS showed higher villus height in the jejunum at 21 days. There were no effects on blood parameters of different diets and growth promoters (P > 0.05), nor on carcass and cuts yield, abdominal fat and relative liver weight (P > 0.05). Broilers receiving the normal diet with EOFOS showed higher villus height in the jejunum at 21 days when compared to the normal diet with antibiotics and the normal diet without growth promoters. However, there were no effects of growth promoters and diet type on broiler performance at 42 days.

The cattle breed Blanco Orejinegro (BON) is an important animal genetic resource in Colombia that needs to be studied to identify its productive benefits for Colombian livestock. The aim of this work was to establish the best linear model that explains the variability for birth weight, weaning weight and yearling weight, and estimate the effect of the serological status for Bovine Viral Diarrhea (BVD) and Bovine Leukosis (BL) in BON cattle in Colombia. The information on animal weighings belonging to 14 BON cattle herds, was collected and cleansed. Using the least squares method, 12 linear models were evaluated including as fixed effects, factors such as herd, sex, weighing month, birth order, season (rainy or dry), birth year, and contemporary group (formed by the concatenation of the factors herd, sex, and birth year). The weighing age was included as a covariate for weaning and yearling weights. For the selection of a model that best describes each parameter, the criteria for choosing models, such as Akaike information criterion (AIC), Bayesian Information criterion (BIC), coefficient of determination (R2), and the sum of squares of the error (SSE), were considered. The model that included the contemporary group showed the best fit, being also the best to describe the three parameters evaluated, since, of the four criteria considered for its evaluation, AIC and SSE showed the lowest values and the highest R2. With this model, weight predictions with higher precision were able to be performed. Employing indirect ELISA screening tests of blood plasma, the serological status of each animal was estimated for BVD and BL viral infections. The serological status of these two viral infections was included in the best-fit model. There was no significant effect of the serological status on the parameters evaluated, so there are indications that animals that came in contact with the virus were not affected during growth.

The aim of this study was to investigate the antibodies and DNA of Leptospira spp. isolated from infected cattle in a small rural dairy farm in a border region between Brazil and Paraguay. Blood and urine samples were collected from 50 Holstein cows aged between 1 and 15 years. The diagnostic tests performed were microscopic serum agglutination for antibody detection and polymerase chain reaction for Leptospira spp. detection. Out of the samples analyzed, 48% were MAT positive with titers ranging from 100 to 400, and the most prevalent antibody was to the serovar Hardjo. One serum sample was amplified to 549 bp for the sec y gene, and sequencing identified it as L. interrogans. This is the first report from northwestern Paraná (PR) State of L. interrogans identification in naturally infected milk cattle. Thus, based on these results, to enhance production efficiency, new serological and molecular studies on dairy cattle from border regions are required to characterize the epidemiology of possible genotypes and their consequences in affected herds.

Export van pgb’s

De Nederlandse regelgeving betreffende persoonsgebonden budgetten (pgb’s) is gebaseerd op het (on)geschreven uitgangspunt dat de zorg of steun waarvoor een pgb wordt aangewend binnen Nederland wordt ontvangen. Deze bijdrage gaat nader in op de vraag of de territoriale beperkingen op het gebruik van pgb’s verenigbaar zijn met het EU-recht, en in het bijzonder de in Verordening 883/2004 opgenomen coördinatieregels voor prestaties bij ziekte, de Patiëntenrichtlijn en/of de verdragsregels inzake het vrije verkeer van diensten. De bijdrage concludeert dat dat in beginsel niet zo is. De vraag is niet waarom een verzekerde of begunstigde het recht zou moeten hebben om zijn/haar pgb in een andere lidstaat te gebruiken. Hij of zij heeft dat recht. De vraag is veeleer waarom een zorgkantoor, zorgaanbieder of gemeente die export zou mogen beperken.

El aprendizaje de los EPM se analizó desde el enfoque instrumental para caracterizar cómo identificaban e interpretaban las estrategias usadas por los niños. Los resultados muestran que los EPM hicieron tres usos diferentes de la progresión de estrategias: como artefacto, generando esquemas de acción instrumental e instrumentando la progresión de estrategias. De estos resultados derivamos implicaciones para la formación de maestros.

Published: June 2020

In this paper, we present the results of mycological research carried out between 2015 and 2018 in the Cieszyn township, in the Silesian Foothills (Outer Western Carpathians). The list of 417 species of macrofungi from the Cieszyn area reported in our previous study, has been expanded further by the addition of 37 taxa found in the current study. Among these, the following deserve special attention: fungi that are new to Poland’s mycobiota (six species: Bryoscyphus dicrani, Discina martinii, Elaphomyces aculeatus, Tuber brumale, T. foetidum, and Russula cerea), taxa subject to legal protection (four species: Disciotis venosa, Grifola frondosa, Mitrophora semilibera, and Sparassis brevipes), as well as fungi that are rare in Poland, included in national or regional red lists, and in the registers of rare and endangered species (24 species including Amanita echinocephala, Arrhenia retiruga, A. spathulata, Catinella olivacea, Elaphomyces maculatus, Hygrophorus discoxanthus, Ophiocordyceps entomorrhiza, Pluteus diettrichii, Tuber aestivum, and T. fulgens). This paper presents the distribution and location of 32 species of fungi along with a short description and illustration of the macro- and micromorphological features of select species and their habitats.
On the right to education in the light of the provisions of the Convention on the Rights of Persons with Disabilities. Idea – declarations and polemics – educational reality
Authors: Mikrut Adam
Published: June 2020

The Polish authorities, before the ratification of the Convention on the Rights of Persons with Disabilities, carried out a thorough analysis of the internal law in order to determine the degree of compliance of its provisions with the provisions of that document. The effects of these analyses have become an important argument for the draft law on ratification of the Conventionsubmitted to the Parliament on the 27th of April 2012 by the Government of our country. In the explanatory memorandum, the Government argued that our country was already ensuring the proper implementation of its provisions, also in the sphere of education. This optimistic view of our legal reality was not shared by everyone. Polemics with declarations propagated by the authorities of the country appeared both before and after the ratification of the Convention, which took place in 2012. They also addressed solutions in the field of education of persons with disabilities, i.e.
compliance of the provisions of our educational law and their practical implementation in accordance with art. 24 of the Conventionen titled „Education”. Various parties spoke out, including the Ombudsman, a state body independent of other authorities. Some of mentioned polemics, but also recommendations made during them, are the content of this article.
Self-advocacy as a form of volunteerism of people with disability
Authors: Nowakowska Iwona
Published: June 2020

Self-advocacy is both a competence necessary for independent adult life and a form of activity of people with disability in terms of exercising their rights to self-determine. It is also a form of social inclusion and participation, often having a character of volunteer engagement of people with disability in work for their minority group. Although the access of people with disability to the sphere of supporting other people is still limited, self-advocacy seems to be a promising form of changing that. In this article self-advocacy and volunteering are discussed in the context of models of disability. The ways how self-advocacy brings to life the functions of volunteerism which concern the creation of self and benefits for the society in general are described. Conclusions are derived with regard to the meaning of self-advocacy and volunteerism in supporting the social participation of people with disability.

Authors: Donatti Adnei , Koslovski Guilherme , Miers Charles
Published: June 2020

A adoção de nuvens computacionais privadas, de pequeno a grande porte, é uma opção para otimização no uso dos recursos computacionais de uma organização. O OpenStack distribui o tráfego de rede entre diversas interfaces e redes virtualizadas, que conectam hosts com serviços de nuvem, divididos em domínio de controle, público ou convidado. O tráfego de controle do OpenStack ocorre através de requisições Rest específicas de cada serviço do OpenStack e por serviços de suporte usando o RabbitMQ. O presente trabalho tem como objetivo caracterizar o tráfego de rede no domínio de controle do OpenStack produzido pela mudança de estado de MVs definindo quanto é trafegado usando requisições Rest e classificando o tráfego agregado no RabbitMQ.

The Probable Effects of the Modernization of the Customs Union Upon the International Road Transportation Sector: Izmir Region Example
Authors: Aydin Ulviyye , Ucar Ahmet , Akpinar Rasim
Published: June 2020

This study aims to detect the probable effects of the modernization of the European Union (EU) – Turkey Customs Union upon the international road transportation sector. Izmir region has been selected as a research area. Izmir is located in the Aegean region, which is the third biggest city and second biggest port of Turkey. With its developed industry due to the region’s raw material resources, qualified labor force, and wide range of transportation opportunities, Izmir is one of the important trade centers, ranking second after the Marmara Region in terms of industry. Closeness to the landlocked centers with high processing capacities such as Manisa, Denizli, Aydin, Mugla, Bursa, Usak, Kutahya, and the presence of around 1,700 companies with international capital makes Izmir more critical for the logistics sector. Thus, it is considered an acceptable sample area for the research. A semi-structured interview technique has been used in the investigation. According to the results of interviews with 19 international road transporters in Izmir, the modernization of the Customs Union will increase Turkey’s competitiveness of trading in goods and services with the EU countries. Removing the obstacles like visa problems, limitations on the free movement of drivers and transportation services, transit tolls that the Turkish road transport companies face in the EU member states, the modernization of the Customs Union will benefit both Turkish road transporters and exporters, as well as increase trade volume between the sides.
