Authors: Abdulla Hazem , Alhashimi Mukhtar , Hamdan Allam Mohammed
Published: July 2019

This study assessed the impact of project management methodologies (PMMs) on project success in the oil and gas industry in the Kingdom of Bahrain. It also explored the different project methodologies used along with their strengths and weaknesses. Quantitative approach with the support of qualitative interviews was used to achieve the objectives of this research. A total of 95 survey responses were received and 17 interviews were conducted. Projects in the oil and gas industry are more about safety than speed, and hence, the use of comprehensive methodologies and applying the relevant methodology elements are important for oil and gas projects. Furthermore, the companies in the oil and gas industry in Bahrain have to pay more attention to their project management methodologies and get it evolved and improved over time to achieve higher project success rates.
Impact of Spirituality in Management
Authors: Sachdeva Geeta
Published: July 2019

In today's times, we live in the changeover period between the ancient meaning of work as subsistence and the new meaning of work as a livelihood. Novel management methods and new organizational systems are necessary to keep up with this emergent context. Spirituality in the workplace states that personnel seek nourishment for both the extents, i.e. their vertical and horizontal, extents of their spirituality at work. It is about people and organizations perceiving work as a spiritual pathway, as a chance to cultivate and to do something for humanity. It is all about care, empathy, and sustenance of others, about truthfulness and persons being truthful to themselves and others, endeavoring to live their values more effusively while performing their work. The present chapter stresses the impact of spirituality in management. The study concludes that for any organization to run efficiently, spirituality is the core to attain happiness, contentment, and success at the same time.
Spiritual Education for Sustainability in Women With Reference to Autobiographies
Authors: Chatterjee Papiya , Mishra Deepanjali
Published: July 2019

Spirituality is more or less measured with religion and morality, where both these words are emotional and deal with the public and private life. If education as widely accepted, is learning to see with new eyes then agreeably attending to spirituality is consciousness of the self and learning. Spirituality is a way of life where a person acquires greater understanding of himself and the outer world. People with spiritual education and awakening, possess a completely different view of the self and the world and further possess greater virtues and good behavioral traits. The chapter further throws light on the need and importance of spiritual education and learning in the lives of women.

Authors: Fanshawe Melissa , Delaney Nicole , Powell Alwyn
Published: July 2019

In higher education learning environments, there is a dual need for educators to use supportive strategies to motivate students throughout the course, while also aiming to increase the capacity of students to self-regulate their learning. Using instantaneous tools to deliver formative or summative feedback through digital technology has been shown to lead to higher achievement and retention rates. This chapter shows how digital badges can provide instantaneous feedback to support students to feel belonging in the online community and develop self-regulation skills. Instantaneous feedback tools can be used to provide teacher presence throughout higher education courses to increase student engagement, retention, and achievement.
Student Perceptions of Screencast Video Feedback for Summative Assessment Tasks in the Creative Arts
Authors: McCarthy Josh
Published: July 2019

This chapter evaluates the use of screencast video feedback for summative assessment tasks in the creative arts and analyzes the advantages and disadvantages of such a format when compared to traditional feedback techniques. In 2017, in the second-year course Narrative Animation at the University of South Australia, video feedback was trialed for summative assessment tasks, in an attempt to improve students' understanding of their academic performance. Thirty-seven students participated in the course and received a five-minute feedback video for each of their three submissions. The video feedback provided to students during the course was evaluated at the end of the semester in the form of two online surveys, allowing participating students with the opportunity to critically reflect on the learning experience. The findings of the study disseminate the learning benefits afforded by the video feedback model and provide insight into the varying attitudes of both students and staff.
Mobile Devices Contribute to Feedback Processes
Authors: Dann Beverly
Published: July 2019

The use of mobile devices such as mobile phones and tablets in education is a problematic field of research that fits within the scope of assessment, mobile technologies, dialogic practices, and more broadly, feedback. This small pilot study investigated how supervising teachers incorporated a mobile device in the form of a video-enabled app into practicums to promote feedback in the form of dialogue and record achievements in alignment with requisite criteria. It further investigated the role of the app in the dialogic feedback process and the interactions between supervising teachers and preservice teachers when they undertake practical performance reviews. The findings showed that using mobile devices aids the dialogic practices of preservice teachers and leads to better outcomes. Despite the evidence, systemic organizational intent will be needed to reinforce the benefits and encourage adoption.

Objective: To compare the retroperitoneal with the transperitoneal approach in a series of patients underwent to robotic-assisted pyelolithotomy (RP). Materials and methods: From January 2015 to December 2018 we evaluated 20 patients subjected to robotic pyelolithotomy; 11 patients were treated with retroperitoneal approach (RRP) and 9 with transperitoneal approach (TRP). For each patient intra and perioperative data were recorded: operative time (OT), blood loss (BL), length of hospital stay (LOS), stone clearance, post-operative complications and time to remove the drain. The presence of stone fragments < 4 mm was considered as stone free rate. Results: The principal stone burden was greater in the TRP group than in the RRP group (48 ± 10 mm vs 32 ± 14 mm, p = 0.12). Preoperative hydronephrosis was present in 7 (64%) patients in RRP group and a mild hydronephrosis in 3 of TRP group (p = 0.04). The average operative time was higher in the RRP group than in the TRP group (203 ± 45 min vs 137 ± 31 min, p = 0.002). The average blood loss was 305 ± 175 ml in the RRP group versus 94 ± 104 ml in the TRP group (p = 0.005). The stone free rate was similar between the two groups, 36% (4 patients) in the RRP group and 44% (4 patients) in the TRP (p = 0.966). Conclusions: RP appears to be a safe and effective minimally invasive treatment for some patients with renal staghorn calculi or urinary tract malformations. The TRP may give lower operative time and better results in terms of blood loss and length of hospital stay.

Authors: Zazzara Michele , Nazaraj Arjan , Colamonico Ottavio , Mastromauro Marcella , Cardo Giuseppe , Ludovico Giuseppe Mario
Published: July 2019

The aim of the present case-series analysis was to assess the safety and efficacy of pollen extract in association with vitamins in order to reduce the chronic prostatic inflammation in patients with class IV chronic prostatitis (CP). Nineteen non-consecutive patients performed a prostate biopsy for a suspect of prostate cancer. The biopsy histopathological examination showed a class IV CP, in presence of mild/moderate/high degree of inflammation, in association with an extensive (multiple biopsy sites, i.e., ≥ 3) high-grade prostatic intraepithelial neoplasia PIN (HGPIN) and/or atypical small acinar proliferation (ASAP). According to EAU Prostate Cancer Guidelines prostate biopsy was repeated after 6 months, because of the presence of extensive HGPIN or ASAP. Oral administration of pollen extract in association with vitamins (two capsules every 24 h) was prescribed until the repeat biopsy. Repeat biopsy histopathological examination showed, in 13 patients (68.4%), a lower degree of inflammation (absent/mild/moderate).

Authors: Simuzingili Tyson , Amosun Seyi Ladele
Published: July 2019

The purpose of this study is to identify the clinical competencies that are expected of physiotherapy students at the University of the Western Cape. A list of ten categories of clinical competencies was first compiled from the literature and administered to 2 lecturers, 5 clinical supervisors and 10 final year students, to elicit their perspectives of expected clinical competencies. Based on the outcome of this, a list of eight categories of competencies was administered to 7 lecturers, 50 clinical supervisors and 31 final year students. Participants were requested to rank the competencies in order of what was considered to be essential. The analysis of 79 responses revealed similarities among lecturers, clinical supervisors and students in the ranking of three competencies, but disparities in the ranking of five competencies. Reasons for the disparities, and the impact of the disparities on students are discussed. Further research is recommended to identify the reasons for the disparities.
The Soweto stroke questionnaire
Authors: Hale L. A. , Eales C. J. , Fritz V. U.
Published: July 2019

A questionnaire was designed for a recent survey into the outcome of stroke patients in Soweto, named the Soweto Stroke Questionnaire (SSQ). It was based on the Barthel ADL Index (BI) but modified to suit the local context. This paper introduces the SSQ, and reports on its inter-rater reliability and its concurrent validity. Fifty-four subjects, in the age range 30 to 75 years, were interviewed and nineteen re-interviewed using the SSQ. Four different scores were calculated: a total score, a Barthel Index score, an Impairment score, and a Quality of Life score. The Pearson’s Correlation Coefficient was found to be high between the total score and the BI score. (r=0.948) which supports the concurrent validity of the developed questionnaire. In assessing the reliability of the SQQ, the Wilcoxin Test showed that there was no significant difference between the initial and repeat interviews for the total score, the Barthel Index score, and the Impairment score (p<0,05). The Quality of Life Score came closer to a difference, but not statistically significantly so. These tests were collaborated by Bland and Altman graphs which showed that in 95% of the time, the questions were repeatable. Mc Nemar’s Test of Symmetry showed that 34 out of 38 questions asked were found to have over 70% correlation. Four questions showed a lower correlation, the lowest being 63.16%. The SSQ was found to have interrater reliability, and to be concurrently valid to the Barthel Index. It is quick and easy to use, requiring no sophisticated equipment or training. It still requires to be investigated for sensitivity and predictiveness, and to be validated in a more general South African stroke population.
Benefits of exercise in older persons at primary level
Authors: Kunda Annie , Amosun Seyi L.
Published: July 2019

The National Department of Health invited comments on proposed policy guidelines on the prevention of physical inactivity in older persons at primary level. The guidelines recommended the use of exercises which are dynamic, interesting, fun, easily implemented, safe and tailored to suit the individual needs. In order to make informed comments on the policy, the aim of this study was to evaluate the impact of the recommended exercise program among older persons in a local community over a six-week period. Promoting physical activity among the participants in the study resulted in marked improvements in systolic and diastolic blood pressures, and dominant hand grip strength. The time taken to perform some selected functional tasks also improved. The findings gave credence to the need to discourage physical inactivity among older persons, but there is need to overcome formidable methodological problems in evaluating the effects of exercise intervention among older persons in the community.
The efficacy of the simplified air cushion (SAC) compared to the polyurethane foam cushion with regard to ischial tuberosity interface pressure relief
Authors: Visser C. , Eksteen C. A.
Published: July 2019

This study was initiated in an attempt to compare the Simplified air cushion (SAC) with the Polyurethane Foam (PU Foam) wheelchair cushion with regard to effective pressure relief the study focused especially on the wheelchair bound spinal cord injured (SCI) patient.Thirty ulcer-free spinal cord injured (SCI) patients participated in this study. Patients were tested on a novice wheelchair cushion, namely the (SAC) as well as on the high-density PU Foam cushion, currently used in government subsidised hospitals. Ischial tuberosity interface pressures were measured under both ischial tuberosities by means of the Oxford Pressure Monitor MK 11 (OPM MK11).Maximum average pressures on the SAC were 73.60 mmHg and 82.97 mmHg on the PU Foam cushion. The results suggest that the SAC provides adequate pressure relief if compared to the PU Foam cushion. Due to the fact that the SAC is designed on the same principles as other air cushions, it provides a maximum support area which distributes the weight of the patient evenly, thereby lowering peak pressures. The SAC also has the ability to allow air circulation at the body interface, which aids in temperature control.

Authors: Krause M. W. , Viljoen M. J. , Bezuidenhout M. J.
Published: July 2019

The move to an outcomes-based education and training system in South Africa presents higher education and training institutions with a challenge to review their curricula and to adapt to changes brought about by the new education and health care dispensations. Key aspects of the move to outcomes-based education and training as contained in the South African Qualifications Authority (SAQA) Act, information regarding the National Qualifications Framework (NQF) and other matters informing curriculum review are addressed. The Department of Physiotherapy of the University of the Orange Free State has just completed the first phase of restructuring its education and training programme in order to submit the qualification for registration on the NQF. The rationale behind the shift to an outcomes-based, student-centred curriculum and the key features of the programme are briefly discussed, as this is the first step towards the registration of unit standards/qualifications, a process which all education and training institutions will have to embark upon soon.

A welcoming guide to social media for cytopathologists: Tips, tricks, and the best practices of social cytopathology
Authors: Dirilenoglu Fikret , Önal Binnur
Published: July 2019

This guide provides an overview of social media (SoMe) use with the recent updates for the “cytopathologists and the ones interested in”. Our aim was to introduce the basic terms and rules, the potential benefits and risks, and some tips and tricks for using SoMe. The two most popular SoMe platforms, Facebook and Twitter, were the focus of this article. Thus far, many pathologists have already proved how efficiently the SoMe services could be utilized; the same applies specifically to the community of cytopathology. In our opinion, the more CPs are involved in SoMe, the more connected, productive, and stronger the community will become.
Cytologic smears improve accuracy of frozen sections of ovarian tumors in the community practice settings
Authors: Cimic Adela , Mironova Maria , Khoury-Collado Fady , Salih Ziyan
Published: July 2019

Background:

The ovaries can be the site for various primary tumors and also the presenting site of metastatic disease. Quick and correct intraoperative diagnosis is crucial for the patient's further management. The aim of this study was to demonstrate the advantages of the combined diagnostic method – ovarian frozen sections in conjunction with cytologic smears.

Methods:

From June 2016 to June 2017, we prospectively prepared additional two cytologic smears with Diff-Quik stain on ovarian frozen sections comprised of two hematoxylin and eosin sections. For quality assurance purposes, we compared the results of frozen section discrepancies and deferrals with those that of the previous year from June 2015 to June 2016.

Results:

With the introduction of cytologic smears to ovarian frozen sections, the number of discrepancies and deferrals combined decreased from 13.75% to 7.85%. The most benefit of smears was observed in primary ovarian malignancies.

Conclusions:

In the setting where all the members of the pathology group render cytologic evaluations routinely, smears play an important complementary role.
Use of the term atypical cells in the reporting of ascitic fluid cytology: A caveat
Authors: Pai Radha Ramachandra , Shenoy Krithika Damodar , Minal Jessica , Suresh Pooja K. , Chakraborti Shrijeet , Lobo Flora D.
Published: July 2019

Background:

Abdominal paracentesis is a routine diagnostic procedure for assessment of patients with recent onset or worsening of ascites.

Objectives:

The objective of the study is to (1) review clinically confirmed cases of malignancy with negative, atypical, and suspicious cytology reports and provide reasoning for discrepancies and (2) recalculate sensitivity, specificity, and predictive values after review.

Materials and Methods:

Papanicolaou smears of ascitic fluid paracentesis samples received over one calendar year were reviewed retrospectively by an expert in cytopathology blinded to the final clinical and/or histopathological diagnoses. Cases with discrepancies after review were noted. Sensitivity, specificity, and predictive values were calculated before and after review of slides. Data were analyzed using SPSS version 16.

Results:

Malignant etiology was identified in 49/115 cases (42.6%) with female genital tract being the most common site of malignancy (22, 44.8%). The remaining 66 (57.4%) had a benign etiology with hepatic cirrhosis in 42 cases (63.6%). A review revealed discrepancies in five cases, three of which were earlier called negative for malignant cells (one case each of ovarian adenocarcinoma, cecal adenocarcinoma, and cholangiocarcinoma). Two cases of ovarian adenocarcinoma that were reported as atypical/reactive mesothelial hyperplasia showed malignant cells upon review. Sensitivity and specificity after review were 69.4% and 100%, respectively, with 100% positive predictive value.

Conclusion:

Being a minimally invasive procedure, abdominal paracentesis continues to be an important diagnostic tool in guiding patient management. A proper morphological assessment with adequate clinical information and correlation with other investigations can be used to arrive at a definitive diagnosis in most cases. The term “atypical” can be misleading and is often used for want of clinical information and is best avoided.
A typical weather pattern for the ozone pollution events in North China
Authors: Gong Cheng , Liao Hong
Published: July 2019

Abstract. Ground-level observations, reanalyzed meteorological fields and a 3-D global chemical and transport model (GEOS-Chem) were applied in this study to investigate ozone (O3) pollution events (OPEs) in North China (36.5° N–40.5° N, 114.5° E–119.5° E) during 2014–2017. Ozone pollution days (OPDs) were defined as days with maximum daily averaged 8-h (MDA8) concentrations over North China larger than 160 μg m−3, and OPEs were defined as periods with 3 or more consecutive OPDs. Observations showed that there were 167 OPDs and 27 OPEs in North China during 2014–2017, in which 123 OPDs and 21 OPEs occurred in May–July. We found that OPEs in North China occurred under a typical weather pattern with high daily maximum temperature (Tmax), low relative humidity (RH), anomalous southerlies and divergence in the lower troposphere, an anomalous high-pressure system at 500 hPa and an anomalous downward air flow from 500 hPa to the surface. Under such a weather pattern, chemical production of O3 was high between 800 and 900 hPa, which was then transported downward to enhance O3 pollution at the surface. A standardized index I_OPE was defined by applying four key meteorological parameters, including Tmax, RH, meridional winds at 850 hPa (V850) and zonal winds at 500 hPa (U500). I_OPE can capture approximately 80 % of the observed OPDs and OPEs, which has implications for forecasting OPEs in North China.
South Pacific Subtropical High from the late Holocene to the end of the 21st century: insights from climate proxies and general circulation models
Authors: Flores-Aqueveque Valentina , Rojas Maisa , Aguirre Catalina , Arias Paola A. , González Charles
Published: July 2019

Abstract. The South Pacific Subtropical High (SPSH) is a predominant feature of South American climate. The variability of this high-pressure center induces changes in the intensity of coastal alongshore winds and precipitation, among others, over southwestern South America. In recent decades, a strengthening and expansion of the SPSH have been observed and attributed to the current global warming. These changes have led an intensification of the southerly winds along the coast of northern to central Chile, and a decrease in precipitation from central to southern Chile. Motivated by improving our understanding about the regional impacts of climate change in this part of the Southern Hemisphere, we analyze SPSH changes during the two most extreme climate events of the last millennium: the Little Ice Age (LIA) and the Current Warm Period (CWP: 1970–2000), based on paleoclimate records and CMIP5/PMIP3 model simulations. In order to assess the level of agreement of general circulation models, we also compare them with ERA-Interim reanalysis data for the 1979–2009 period as a complementary analysis. Finally, with the aim of evaluating future SPSH behaviour, we include 21th century projections under a RCP8.5 scenario in our analyses. Our results indicate that during the relative warm (cold) period, the SPSH expands (contracts). Together with this change, alongshore winds intensify (weaken) south (north) of ~ 35º S; also, Southern Westerly Winds become stronger (weaker) and shift southward (northward). Model results generally underestimate reanalysis data. These changes are in good agreement with paleoclimate records, which suggest that these variations could be related to tropical climate dynamics but also to extratropical phenomena. However, although models adequately represent most of the South American climate changes, they fail in representing the Intertropical Convergence Zone - Hadley Cell system dynamics. Climate model projections indicate that changes recently observed will continue during next decades, highlighting the need to establish effective mitigation and adaptation strategies against their environmental and socio-economic impacts.
Rural Road Extraction using Object Based Image Analysis (OBIA): A case study from Assam, India
Authors: Medhi Ankita , Saha Ashis Kumar
Published: July 2019

Abstract. Rural roads in India have been considered as significant component for overall rural development. In India, the status of rural road connectivity is not up to the mark in some of the states. For providing better connectivity in the rural areas the information on roads are considered important. Detailed mapping of the roads can be useful for planning further road connectivity and proving access to facilities in the rural areas. For detailed mapping of roads higher resolution satellite imageries are required. Object based Image Analysis (OBIA) has emerged as a promising map analysis approach using high and very high resolution imageries. Feature extraction is one of the important aspect in OBIA extracting features such as roads, buildings, water bodies and other important features of interest from the high resolution imageries. In the present study, an attempt has been made to extract rural roads of Titabor in Jorhat district of Assam (India). Various OBIA based extraction methods have been used for extracting roads using high & very high resolution Resourcesat-II (5.8 m) and Kompsat imagery (2.8 m MS & 0.7 m PAN). The results have been compared and relative advantages were evaluated.
Mapping Violent Presence of Armed Actors in Colombia

Published: July 2019

Abstract. Heat maps and Early Warning Systems have traditionally contributed to identifying and managing risks associated with crime trends, health hazards, and natural disasters. However, their application to analyzing civil war dynamics still is at an early stage. To address this need, this research integrates Natural Language Processing (NLP) tools and Geographic Information Systems (GIS) to generate an interactive map of the violent presence of armed actors in the Colombian civil war between 1988 and 2017. The NLP component generates fine-grained geo-location data of armed actors' violent presence. The GIS component then uses the geo-referenced data to present dynamic clusters of four main types of actors: Government forces, Insurgent organizations, Paramilitary groups, and Criminal organizations. Each type of actors is further disaggregated into a multitude of specific armed organizations. Based on anomalies in the spatio-temporal trends identified in the data, we develop an EWS methodology to detect “emerging”, “intense”, and “critical” cases. This application contributes to the efforts of the academic and policy communities to understanding the spatio-temporal dynamics of political violence and promoting sustainable peace in civil war settings.
Using GIS and cartography as part of the whole-of-society approach to determine coercion into marine wildlife poaching and piracy
Authors: Schmitz Peter , Gonçalves Duarte
Published: July 2019

Abstract. This paper builds on a previous paper on determining a community’s vulnerability to coercion into wildlife crimes along South African game reserves with a focus on rhinoceros poaching. This paper looks at the profiling of coastal communities along the South African coast for possible coercion into piracy and marine wildlife crime as context for a whole-of-society approach. As with the previous paper the criteria and data are based on publicly available resources to do the profiling. Criteria range from access to motorised boats, history of illegal, unregulated and unreported fishing activities, poverty, unemployment, closeness to marine reserves and levels of education. The criteria for piracy are based on articles and reports on the reasons for piracy along the Somalian coast. From the analysis the highest risk for piracy is the south-western Cape around Cape Town since the proximity to international sea routes, the ability of the local population to do deep-sea fishing and existing gang activity. The risk to marine resources is similar owing to the same reasons as for piracy. It is a known fact that gangs are involved in the poaching of abalone along the south-western Cape coast. Socio-economic risks are higher along the east coast of South Africa owing to higher unemployment, poverty and lower education levels.
Network-based Visualisation of Accessibility for a Public Transport System
Authors: Keler Andreas , Bug Lukas A. , Krisp Jukka M.
Published: July 2019

Abstract. Network-based visualisation provides a detailed and accurate way of estimating accessibilities in cities. In this paper, the city of Augsburg serves as an example for modelling changes in network-based accessibility inside the inner city. For improving the urban public transport network, the central transportation hub “Königsplatz” recently underwent a major reconstruction. Therefore, a central detour of tram services was established. The change of accessibility is investigated using OpenStreetMap as database. The analysis was performed by a comparison of the spatiotemporal accessibility with bus and tram, in the period during and after the reconstruction. Geovisualisation of this accessibility analysis is accomplished via colour-coded accessibility maps and 3D-areal maps. A major change of accessibility can be detected between the reconstruction and post-reconstruction phase. Furthermore, this accessibility analysis reveals a far worse accessibility of public transportation in the eastern part compared to the western part of the city centre in Augsburg.

Published: July 2019

Abstract. Our research is based on a large case study of Unmanned Aerial Vehicle (UAV) surveys, modelling and visualizations of the Doblar accumulation basin. The various approaches for UAV surveying of large, demanding terrain configurations, and the benefits of surveying products used as a basis for other interdisciplinary hydrological and environmental services were researched. The demanding mountainous terrain, the steep slopes and deep and narrow streams required detailed pre-planning of the survey, including the pre-survey terrain overview. The accumulation basin was emptied merely for a short period; thus, the survey was performed in unfavourable weather conditions, which included coldness, snowfall and wind. Point clouds were generated and georeferenced from the 4377 recorded photos. The dense point cloud contained approximately 222 million points in the medium setting and more than a billion in the high setting. A 3D model was built from the data. This became the basis for numerous further analyses and for the presentation using cartographic principles: a digital elevation model with a resolution of 10 cm, an orthophoto with a resolution of 10 cm, a 3D model draped with orthophoto, contour lines with a 1 m interval, topographic profiles, calculations of volumes at different water levels, a flythrough, augmented reality and a video simulation of the water level changes. The model can also serve as a basis for hydraulic and environmental analysis and simulations or used for analyses of the accumulation and deposition of river material compared with previous and future surveys.

Published: July 2019

Abstract. Sea ice volume export through the Fram Strait plays an important role on the Arctic freshwater and energy redistribution. The combined model and satellite thickness (CMST) data set assimilates CryoSat-2 and Soil Moisture and Ocean Salinity (SMOS) thickness products together with satellite sea ice concentration. The CMST data set closes the gap of stand-alone satellite-derived sea ice thickness in summer and therefore allows us to estimate sea ice volume export during the melt season. In this study, we first validate the CMST data set using field observations, and then estimate the continuous seasonal and interannual variations of Arctic sea ice volume flux through the Fram Strait from September 2010 to December 2016. The results show that seasonal and interannual sea ice volume export vary from −244 (±43) to −973 (±59) km3 and −1974 (±291) to −2491 (±280) km3, respectively. The sea ice volume export reaches its maximum in spring and the mean amount of the melt season ice volume export accounts about one third of the yearly total amount. The minimum monthly sea ice export is −11 km3 in August 2015 and the maximum (−442 km3) appears in March 2011. Seasonal variations of sea ice thickness and drift frequency distributions infer that the thicker ice accompanied with slower ice motion is easier to appear when there is sea ice exporting through the Fram Strait outlet in summer.

Terminalia fagifolia Mart. et Zucc é uma espécie encontrada no Cerrado brasileiro, empregada na medicina popular para tratar aftas e tumores e utilizada pela comunidade tradicional Mumbuca/Jalapão – TO. Objetivou-se com esse estudo avaliar a ação antibacteriana dos extratos brutos etanólicos da casca e das folhas da T. fagifolia sobre Staphylococcus aureus. Determinou-se a atividade antibacteriana através da difusão em ágar, método dos poços, e pela técnica da Concentração Inibitória Mínima (CIM). Na técnica de difusão em ágar o extrato da casca apresentou melhor atividade antibacteriana que o extrato das folhas. Na análise da determinação da Concentração Inibitória Mínima, os extratos da casca e das folhas apresentaram CIM de 75 mg/mL, respectivamente, inibindo o crescimento de 100% e mais de 90% do inóculo bacteriano. Portanto, é fundamental a continuidade dos estudos com essa espécie, pois os extratos etanólicos revelaram atividades antibacterianas importantes.
URBANIZAÇÃO NO CERRADO: A URBANIZAÇÃO E A EXPANSÃO DA AGRICULTURA CAPITALISTA NOS MUNICÍPIOS DE RIO VERDE-GO E JATAÍ-GO
Authors: DE SOUZA TATIANE RODRIGUES
Published: July 2019

O processo de modernização nas áreas do Cerrado acarretou uma série de mudanças nas estruturas produtivas, gerando inúmeras alterações espaciais nos municípios inseridos nesse processo. Dentro dessas novas conformações espaciais as reestruturações e refuncionalizações adaptam-se as organizações espaciais, às novas funções econômicas e técnicas dos espaços produtivos, inclusive no urbano. Nessa perspectiva procurar-se-á analisar as particularidades da urbanização no Cerrado, a partir da expansão do modelo técnico produtivo que se impôs como a ampliação da apropriação do modo capitalista e suas repercussões na organização urbana. Para exemplificar, apresenta-se algumas características urbana das cidades de Rio Verde e Jataí, ambas localizadas no Sudeste de Goiás, principal região produtora de commodities do estado. O texto apresenta um caráter analítico, baseia-se principalmente na literatura que aborda essa temática e na observação direta nas áreas urbanas das referidas cidades. Constata-se que além da organização de um sistema técnico requerido pelo modelo produtivo, há uma segregação urbana, marcada pelos segmentos que estão incluídos e excluídos dessa formação sócio-espacial.

O sistema geovitícola de Classificação Climática Multicritério (CCM), baseado nos índices climáticos: Índice Heliotérmico (IH); Índice de Frio Noturno (IF) e Índice de Seca (IS), foi utilizado para identificar o potencial climático para produção de uvas viníferas e regionalizar a vitivinicultura na região do Polo Regional Leste Paulista. Nas safras de verão (setembro a fevereiro) e de inverno (março a agosto) verificou-se que o IS classificou a região como sendo de clima úmido. A CCM permitiu verificar que a condição climática durante a safra de inverno indica potencial vitivinícola mais adequado em comparação às da safra de verão. Para a safra de inverno, as classificações da CCM: IH-1/IF+2/IS-2; IH-2/IF+2/IS-2 e IH-3/IF+2/IS-2 são encontradas em áreas com maior altitude (acima de 980m) com IH inferior a 2100 unidades, como observado nas encostas da Serra da Mantiqueira, sendo similares às encontradas em tradicionais regiões produtoras de vinho fino na Europa. As classificações encontradas: IH+2/IF+1/IS-2 e IH+1/IF+1/IS-2 ocorrem em regiões de menor altitude (abaixo de 980 m) com IH superior a 2100 unidades e estão localizadas a oeste da região de estudo

Atualmente observa-se que o ser humano utiliza os espaços segundo suas necessidades e seus valores individuais ou coletivos, o que afeta o equilíbrio dinâmico da natureza. Nesse sentindo, existe uma necessidade em encontrar explicações e soluções por parte de pesquisadores para os impactos que são gerados diante das intervenções do homem ao meio ambiente. Com isso, o trabalho tem como objetivo principal, identificar as principais atividades antrópicas na bacia hidrográfica do Córrego Matriz no período de 2000 a 2015, e seus possíveis reflexos ao meio ambiente. Pode-se destacar nos mapas de uso e ocupação da terra, no período de quinze anos, que a pastagem é o uso predominante nas áreas ocupadas da bacia. Apesar de apresentar-se um acréscimo dos remanescentes florestais (matas/cerrado) nos últimos anos, principalmente junto aos locais de nascentes, a intensificação da pecuária vem se tornando as causas dos principais impactos ambientais na área de estudo, como feições erosivas e assoreamento dos cursos d’água.

Bacteria of the genus Salmonella are gram-negative rods, facultative anaerobic non-spore formers, which may or may not be flagellated. These bacteria are frequently detected in poultry products and are important in animal and public health. The purpose of this study was to investigate the occurrence of Salmonella spp. in feces from broiler chicken litters located in municipalities of the central region of the state of Minas Gerais, Brazil. The study analyzed 845 feces samples from different poultry farms collected between September 2016 and March 2017. Pre-enrichment broths, specific selective broths and selective indicator agar were used for the analyses. The suspected isolates were submitted to biochemical testing and serotyping with “O” and “H” antisera to identify the Salmonella serotypes. The results showed that 213 feces samples were contaminated with Salmonella, and the serotypes found were: S. Minnesota, S. Sandiego, S. Schwarzengrund, S. Infantis, S. Hadar, S. enterica subsp. enterica (O: 4.5), S. Montevideo, S. Miami, S. Heidelberg, S. Cerro, S. Ndolo, S. Panama, S. Anatum, S. Tennessee, S. Agona, S. Newport and S. Muenster. The Minnesota serotype was predominant among the isolates investigated. Actions to improve the biosafety of commercial poultry farms are necessary to prevent possible contamination of poultry products that endanger human health.
INSIGHTS INTO THE CURE CHEMISTRY OF BROMINATED BUTYL RUBBER

Published: July 2019

The importance of dehydrobromination to the cure chemistry of brominated butyl rubber (BIIR) is demonstrated through a combination of cure rheometry studies and model compound experiments. These data show that, while HBr elimination to give an exomethylene conjugated diene is inevitable, subsequent reactivity is highly sensitive to acidity within the mixture. As a result, formulations containing acid scavengers such as epoxides or MgO produce cure dynamics and yields that differ markedly from those of unstabilized analogues. These differences in allyl cation reaction pathways underlie much of the known behavior of BIIR + ZnO compounds and have a substantial effect on the progress of sulfur-based cure formulations. In this report, allyl cation fragmentation and electrophilic addition mechanisms are developed from 1H nuclear magnetic resonance (NMR) and mass spectrometry analysis of model compounds, and their implications for sulfur, ZnO, and sulfur + ZnO vulcanization chemistry are detailed.
Sons of the Country: Nasser, Qutb, and the Struggle that Defined Egypt
Authors: Calvert John
Published: July 2019

Books on Islamism and the bureaucratic-authoritarian regimes of the Arab World are a scholarly staple. In Making the Arab World, Fawaz Gerges breaks from the pack. Rather than focus on either Islamism or Arab state regimes as isolated phenomena, as many have done, he regards them in tandem. Islamism and Arab nationalism, he writes, have since the mid-twentieth century been engaged in a dialectical relationship; one fully cannot persist without the other. To make his case, Gerges draws on the biographies of Sayyid Qutb, the mercurial ideologue of radical Islamism, and Abdel Nasser, the pragmatic architect of the Egyptian Republic. Political power, not ideology, was the driver of the conflict between the two. The result is a book of nuance and insight.
Is Islamophobia (Always) Racism?
Authors: Lauwers Anna Sophie
Published: July 2019

Recent scholarship increasingly defines Islamophobia as a form of racism. The possibility that Islamophobia could also manifest itself as religious or cultural bigotry is generally overlooked. This article argues that although anti-Islam bigotry is intertwined with anti-Muslim racism, the two are conceptually distinct. Making this distinction allows us to better analyze, unmask, and critically assess Islamophobia. The article conceptually explores the similarities and differences between anti-Muslim racism and anti-Islam bigotry. It finds that although anti-Islam bigotry implies a prejudicial rejection of an essentialized idea of Islam, it understands religion or culture to be an individual choice and allows for the possibility that Muslims convert or assimilate. As such, it differs from anti-Muslim racism, which implies that the Muslim identity and the negative characteristics associated with Islam are innate and unchangeable. The article argues that contemporary Islamophobic political discourse in Europe is predominantly racist, although it hides behind a cloak of anti-Islam bigotry.

Background: The goal of this study was to compare the performance of several
database algorithms designed to identify red blood cell (RBC) Transfusion Related
hospital Admissions (TRAs) in Veterans with end stage renal disease (ESRD).Methods:
Hospitalizations in Veterans with ESRD and evidence of dialysis between 01/01/2008 and
12/31/2013 were screened for TRAs using a clinical algorithm (CA) and four variations of
claims-based algorithms (CBA 1–4). Criteria were implemented to exclude patients with
non-ESRD-related anemia (e.g., injury, surgery, bleeding, medications known to produce
anemia). Diagnostic performance of each algorithm was delineated based on two clinical
representations of a TRA: RBC transfusion required to treat ESRD-related anemia on
admission regardless of the reason for admission (labeled as TRA) and hospitalization
for the primary purpose of treating ESRD-related anemia (labeled TRA-Primary). The
performance of all algorithms was determined by comparing each to a reference standard
established by medical records review. Population-level estimates of classification
agreement statistics were calculated for each algorithm using inverse probability
weights and bootstrapping procedures. Due to the low prevalence of TRAs, the geometric
mean was considered the primary measure of algorithm performance.Results: After
application of exclusion criteria, the study consisted of 12,388 Veterans with 26,672
admissions. The CA had a geometric mean of 90.8% (95% Confidence Interval: 81.8, 95.6)
and 94.7% (95% CI: 80.5, 98.7) for TRA and TRA-Primary, respectively. The geometric mean
for the CBAs ranged from 60.3% (95% CI: 53.2, 66.9) to 91.8% (95% CI: 86.9, 95) for TRA,
and from 80.7% (95% CI: 72.9, 86.7) to 96.7% (95% CI: 94.1, 98.2) for TRA-Primary. The
adjusted proportions of admissions classified as TRAs was 3.2% (95% CI: 2.8, 3.8) and
TRA-Primary was 1.3% (95% CI: 1.1, 1.7).Conclusions: The CA and select CBAs were able to
identify TRAs and TRA-primary with high levels of accuracy and can be used to examine
anemia management practices in ESRD patients.

Published: July 2019

En este artículo se presentará el diseño e implementación de una planta en una empresa industrial que permita el reaprovechamiento de los residuos sólidos (viruta de cuero) del proceso de curtido durante el proceso de elaboración de cueros para su utilización en un proceso complementario. Los problemas que se presentan al no contar con este tipo de procesos es incurrir en costos extras para tercerizar servicios para la disposición de estos desechos contribuyendo al aumento de la contaminación en la ciudad. Para implantar esta mejora será necesario realizar un análisis preliminar para poder elaborar la propuesta de diseño de planta más óptima que se adecúe a este proceso. La línea productiva está constituida por cuatro Unidades, la primera Unidad de Acondicionamiento de materia prima; la segunda Unidad de Mezclado y Moldeado; la tercera Unidad de Prensado y Secado, y finalmente la Unidad de Acabado.
