Background: With the advancement of science, the scope of thyroid uptake in diagnosis and treatment of thyroid diseases has become limited. Uptake test with 99mTc pertechnetate along with a thyroid scan, which is done almost routinely, could be a better option when needed. This will not only exempt the patients from relatively higher radiation burden but also cause significant reduction of procedural time. Moreover, the thyroid image we get along with the uptake may guide with additional information. This study was done to provide preliminary data regarding thyroid uptake test with 99mTc in our population and to assess the possibilities of introducing this safer and convenient radionuclide in our routine practice.

Patients and methods: This cross sectional, comparative study was conducted from January to December of 2015 on 59 participants in Institute of Nuclear Medicine and Allied Sciences, Dhaka. Patients coming for a radioactive iodine uptake test along with a thyroid scan were enrolled. Uptake of 99mTc pertechnetate at 20 minutes and at 24 hours was measured. Data were analyzed between the two uptake values based on clinical conditions, serum TSH levels and gland size.

Results: Almost perfect agreement and a strong positive correlation (Kappa value=0.933 & r =0.845) were found between the results of two modalities. The hyperthyroid group showed a moderate agreement (k=0.5) and a moderate positive correlation (r=0.6). The participants with thyroiditis revealed a perfect agreement (k=1) and a strong positive correlation (r=0.981). Almost perfect correlation was found between participants with enlarged and non-enlarged glands (r=0.776 & 0.801 respectively). Agreement analysis revealed almost perfect agreement (k=0.88) in the group with enlarged and moderate agreement (k=0.6) in participants with non-enlarged glands. Low serum TSH group showed perfect agreement (k=1.0) and a strong positive correlation (r=0.748). The group with normal TSH level revealed a perfect agreement with k=1 but a moderate correlation (r=0.418).

Conclusion: Good agreement and correlation were found between thyroid uptakes of 99mTc at 20 minutes by gamma camera and that of at 24 hours. Agreement and correlation in different clinical settings also showed consistency. So, 99mTc may be considered for uptake test in a regular basis in the limited fields where an uptake is still required as it may yield a reliable result in a simple, quicker and more convenient method.

On Four New Methods of Analytical Calculation of Rocket Trajectories
Authors: Campos Luís , Gil Paulo
Published: August 2018

The calculation of rocket trajectories is most often performed using purely numerical methods that account for all relevant parameters and provide the required results. There is a complementary need for analytical methods that make more explicit the effect of the various rocket and atmospheric parameters of the trajectory and can be used as test cases with unlimited accuracy. The available analytical methods take into account (i) variable rocket mass due to propellant consumption. The present paper includes four new analytical methods taking into account besides (i) also (ii) nonlinear aerodynamic forces proportional to the square of the velocity and (iii) exponential dependence of the mass density with altitude for an isothermal atmospheric layer. The four new methods can be used in “hybrid analytical-numerical” approach in which: (i) the atmosphere is divided into isothermal rather than homogeneous layers for greater physical fidelity; and (ii) in each layer, an exact analytical solution of the equations of motion with greater mathematical accuracy than a numerical approximation is used. This should allow a more accurate calculation of rocket trajectories while discretizing the atmosphere into a smaller number of layers. The paper therefore concentrates on four analytical methods of calculation of rocket trajectories in an isothermal atmospheric layers using new exact solutions of the equations of motion beyond those currently available in the literature. The four methods are developed first for the simpler case of a vertical climb and will be subsequently extended to the practically more relevant case of a gravity turn.

TTV-determined Masses for Warm Jupiters and Their Close Planetary Companions
Authors: Wu Dong-Hong , Wang Songhu , Zhou Ji-Lin , Steffen Jason H. , Laughlin Gregory
Published: August 2018

Although the formation and the properties of hot Jupiters (with orbital periodsP< 10 days) have attracted a great deal of attention, the origins of warm Jupiters (10 <P< 100 days) are less well studied. Using a transit timing analysis, we present the orbital parameters of five planetary systems containing warm Jupiters, Kepler 30, Kepler 117, Kepler 302, Kepler 487, and Kepler 418. Three of them, Kepler-30 c(Mp = 549.4 ± 5.6 M⊕), Kepler-117 c(Mp = 702 ± 63M⊕), and Kepler 302 c(Mp = 933 ± 527M⊕), are confirmed to be real warm Jupiters based on their mass. Insights drawn from the radius–temperature relationship lead to the inference that hot Jupiters and warm Jupiters can be roughly separated byTeff,c = 1123.7 ± 3.3 K. Also,Teff,cprovides a good separation for Jupiters with companion fraction consistent with zero (Teff>Teff,c) and those with companion fraction significantly different from zero (Teff<Teff,c).

Authors: Tani Klejda , Kola Irena , Shpata Vjollca , Dhamaj Fregen
Published: August 2018

BACKGROUND: Knee osteoarthritis is a chronic degenerative disease, known as the most common cause of difficulty walking in older adults and subsequently is associated with slow walking. Functional decline, increased risk of falls and the presence of pain are, in many studies, related to the muscle weakness caused by osteoarthritis especially weakness of the quadriceps muscles. Many studies have shown that the strength of the quadriceps femoris muscle can affect gait, by improving or weakening it. Kinesio Tape is a physiotherapeutic technique, which reduces pain and increases muscular strength by irritating the skin receptors.AIM: This study aimed to verify if the application of Kinesio Tape on quadriceps femoris muscle increases gait speed while decreasing the time needed to accomplish the 10-meter walk test in patients with knee osteoarthritis and also in subjects without knee osteoarthritis.METHOD: In this study, we observed the change of gait speed with the help of the 10-meter walk test before, one day and three days after the application of Kinesio Tape in quadriceps femoris muscle. We compared the results of the time needed to perform the 10-meter walk in two groups. In the first group, the Patients group, participated 102 out-patients with a clinical diagnosis of primary knee osteoarthritis, while in the second group, the Control group, participated 73 subjects with a main excluding criterion a clinical diagnosis of primary knee osteoarthritis.RESULTS: Our results indicated that there was a significant decrease of time needed to perform the 10-meter walk test in both groups three days after application of Kinesio Tape on quadriceps femoris muscle. However, there was not a significant change one day after the application of Kinesio Tape compared before its application in both groups.CONCLUSIONS: Our results indicated that there was a significant decrease in time needed to accomplish the 10-meter walk test. Kinesio Tape is a technique that can be used especially when changing walking stereotypes is a long-term goal of the treatment.

The Application of Crowdsourced Processes in a Business Environment
Authors: Kopeć Katarzyna , Szopa Anna
Published: August 2018

The recent shift towards a polycentric perception of business making requires the involvement of stakeholders in an organization's management. This is a starting point for looking at the idea of crowdsourcing as an innovative business model. The inclusion of stakeholders in the process of developing new products or services forms a general foundation of this notion. Entrepreneurs take advantage of crowdsourcing ventures due to the delegation of tasks to stakeholders in the form of an open call. Crowdsourcing interacts dynamically with interconnected society of today. This trend is symbolized by the turn from a consumer to prosumer and from a content consumer to content creator. The chapter exemplifies the types of crowdsourcing with reference to recent research outcomes. Additionally, it presents crowdsourcing incentives and tackles the problem of ethical and legal risks that face crowdsourcing.
Business Sustainability Indices
Authors: Sambhanthan Arunasalam
Published: August 2018

Business sustainability models and indices are useful in theorizing and measuring organizational elements of sustainability. It is often the case that there are not many models and scales out there in the literature for theorizing business sustainability. Existing sustainability models from the published literature are reviewed. The review suggests that there is not much documented research in business sustainability typologies. There is a considerable amount of research required from the applied researchers working in this area to contextualize and re-specify the business sustainability typologies to differing industry clusters such as e-learning, agriculture, manufacturing, and healthcare. In addition to this, the chapter also reviews the existing indices available out there in the literature to measure sustainability. A summary of existing sustainability indices available to measure sustainability at country level and a number of business sustainability indices have been presented. This is followed by a discussion of future research directions.
Cognitive Ergonomics in 2016
Authors: Lofaro Ronald John
Published: August 2018

Cognitive ergonomics deals with decision making, skilled performance(s), and training. This chapter will show what began as a cognitive task analysis (CTA) for identifying critical skills needed for skilled performance, with decision making involved in every step. Over the years, it evolved into a paradigm that extended far beyond a CTA. With the advances in technology, especially communication technologies, some of this paradigm has re-emerged in what are termed estimate-talk-estimate (ETE) efforts, which can be web-based. ETE's are aimed at forecasting, decision making, even policymaking. This chapter will show how to integrate the elements of paradigm cited above with elements of Pareto analysis ETE in order to use today's technology to achieve extremely accurate results across many venues. The model that results from this integration will be used on three current problem areas to show how decisions can be made on standards, policy, and training needs. The problem areas encompass national education standards, aviation and operational testing (OT), and evaluation.

Published: August 2018

Capitalizing on Web 2.0 to improve communication and knowledge sharing among stakeholders, a new form of business processes (BP), called social business processes (SBP), has emerged. This chapter provides a social business process meta-model called SBP2M that enriches an existing business process meta-model with social aspect. It also proposes a domain-specific language (DSL) for SBP modeling. This DSL is defined based on SBP2M and developed as an extension of the standard BPMN notation. The proposed DSL is simple and yet generic thanks to the reduced number of extensions and its ability to model SBP regardless of the used Web 2.0 technology. To show the applicability of the proposed notation, the authors have implemented it within the BPMN2 modeler editor.
Viewpoints on Business Process Models
Authors: Bruno Giorgio
Published: August 2018

Over the past few years, a number of viewpoints have influenced the design of notations for business processes. They emphasize the different elements (tasks, business entities, and roles) that compose business process models; for this reason, they are referred to as activity-centric, data-centric, and role-centric viewpoints. The activity-centric viewpoint focuses on the orchestration of operational activities, which encompass human tasks and automatic ones. On the contrary, the data-centric viewpoint stresses the identification of the key business entities and their lifecycles consisting of states and transitions. In the role-centric viewpoint, a process model is made up of several “role” models; each role model provides a restricted view of the process limited to the behavior of the role under consideration. This chapter illustrates how the above-mentioned viewpoints can be extracted from a global model, with the help of an example concerning the submission of papers to conferences.

Human resource development (HRD) professionals are seeking ways to address rapid, continuous changes in technology and some, unfounded, fears and concerns regarding the influence of globalization on middle-class workers. Globalization efforts do not need to equal unemployment for American middle-class workers. Globalization can add opportunities for American middle-class workers to increase their job prospects by learning new skills, including how to leverage technological innovations for their advantage within the global job market. HRD professionals have an opportunity to assist workers with their skill development and improvement.
The Concept of Modularity in the Context of IS Project Outsourcing
Authors: Benazeer Shahzada , Huysmans Philip , De Bruyn Peter , Verelst Jan
Published: August 2018

Information systems (IS) outsourcing became a very common practice in developed and in emerging economies. Over 94% of Fortune 500 companies are outsourcing at least one major business function. Despite IS outsourcing's popularity, failure rates are high. Many remedies are proposed in the literature, but failure rate of IS outsourcing projects remains high. It seems these remedies turned out to be partially successful at best. This chapter presents an alternative, new perspective on how to avoid IS project outsourcing failures and explores the concept of modularity and normalized systems theory (NST) in relation to IS outsourcing projects. Such a new perspective, which originates from the system sciences, may add value to outsourcing risk analyses. A case study analysis of a failed IS outsourcing project has been conducted. This study illustrates how the concept of modularity and normalized systems theory can be applied ex ante in order to mitigate the risk factors in IS outsourcing projects.
Discrete Event Simulation in Inventory Management
Authors: Duong Linh Nguyen Khanh , Wood Lincoln C.
Published: August 2018

Perishability and substitutability are two key attributes that cannot be ignored in supply chain management. Once produced, perishable products have a finite shelf life. When expired, they are either partially or wholly value-less. The more time that perishable inventory is in storage, the less time it is available for sale to customers. Product substitution is a possibility when considering multiple products. Research indicates that an alternative product is willingly chosen by customers if the preferred one is out of stock. Managers must decide on the replenishment time and replenishment quantity for each item within product subcategory to maximize expected profits under uncertain demand while minimizing the instances of running out of inventory (i.e., a stock out). The combination of these factors often requires simulation models to be developed to understand the behavior of the system as the parameters change. Simulation can incorporate stochasticity and complexity while providing detailed output for further analysis and optimization work.

Missing Part of Halal Supply Chain Management
Authors: Hendayani Ratih , Fernando Yudi
Published: August 2018

The Halal product industry should make sure all companies, especially companies supply chains, guarantee product Halalness. Some research about Halal supply chain is already published and gives various perspectives about this topic. Unfortunately, one thing not discussed in the previous research is an Islamic financial system that actually supports operation of the Halal supply chain because the Halal supply chain cannot be Halal or barakah if the supply chain financing does not also comply with Islamic law. This chapter discusses Islamic financial systems that include the Halal supply chain such as a Halal fund for the supply chain cost and Halal Financial flow and brings a new perspective and definition of Halal supply chain management.
Notions of Maritime Green Supply Chain Management
Authors: Jasmi Fairuz , Fernando Yudi
Published: August 2018

Maritime supply chain is arguably the most imperative service sector for facilitating intercontinental trade globally. Within these complex supply chain systems, shipping organizations, port authorities, and import-export firms collaborate and cooperate with each other in the broader management context of maritime logistics. Meanwhile, increasing environmental concerns have forced global maritime organizations to implement sustainability in their operation. MGSCM is a recent focus within the sustainable supply chain body of literature with ample room for understanding its challenges and opportunities. With that in mind, the objective of this chapter is to review the literature on the development of GSCM and conceptualizing the notion of MGSCM concept in maritime context derived from GSCM, respectively. This chapter is unique because it addresses the complex dimension of sustainability in maritime supply chain and tries to define it in line with the existing GSCM context. The findings of this chapter show that GSCM can be extended into the maritime perspective to define MGSCM.

Published: August 2018

Managing supply chain relationships or working with suppliers to meet the goal of waste reduction are essential functions for successful businesses. There are several disruption risks associated in supply chains, of which few can argue that the disruption of communication, especially product identification and data capture, is the most important potential bottleneck. It is important in a lean environment to identify potentially disruptive supply chain events for each node in the network. The use of RFID and related IT-intensive technologies can greatly aid management in its quest for more robust and agile supply chains, especially in an offshoring/outsourcing environment.
A Review of Supply Chain Risk Management in Agribusiness Industry
Authors: Widiyanesti Sri , Fernando Yudi
Published: August 2018

Supply chain of agricultural commodities becomes a major concern of Indonesian scholars and practitioners. Many companies engaged in this industry are unable to survive in the market. This is contrary to the natural conditions of Indonesia with abundant natural resources and plenty of commodity producers. Problems often arise in the field of supply chain risk which link to commodities in Indonesia: price fluctuation, the scarcity of the commodity, supply and demand are not balanced, distribution and production costs are expensive, raw material commodities that are imported, and natural disasters. Companies that engage in agricultural business have high risk of failure. To overcome this, this chapter reviews supply chain management concept by looking at risk consideration that may raise business uncertainties. The lack of studies to investigate the risk factors in agribusiness makes this study contribute to the supply chain literature.

Authors: Janeš Aleksander
Published: August 2018

In their endeavor to increase profits, companies usually become aware that this is predominantly the result of employee competence and satisfaction, excellent processes, and customer's satisfaction. Based on that assertion, companies integrate different managerial tools in the performance measurement system (PMS) and therefore in their management system. One of the most dominant managerial tools is the Kaplan and Norton's balanced scorecard (BSC). In this chapter, the approach that represents the basis for further work in the field of research in PMSs of companies, with the use of econometric tools, was empirically tested and developed.
Making Sense of IS Project Stories
Authors: Dalcher Darren
Published: August 2018

Stories of failure make a compelling read. However, researchers with a keen interest in information systems failures face a double challenge. Not only is it difficult to obtain intimate details about the circumstances surrounding such failures, but there is also a dearth of information about the type of methods and approaches that can be utilized to collect, describe, and disseminate such information. The purpose of this chapter is to highlight some of the available approaches and to clarify and enhance the methodological underpinning available to researchers. The chapter begins by framing IS project failures in context, before highlighting the role of forensic failure investigation and the typical tools employed in gathering information. It encourages a move from case studies to case histories to capture the essence, dynamics, and complexities of failure stories. It concludes by introducing a new range of ante-narrative approaches that represent future developments in the study of IS failures, enabling a richer interpretation of linked factors that underpin IS failures.

Published: August 2018

This article describes how Smarandache defined neutrosophic sets to handle problems involving incomplete, indeterminacy and awareness of inconsistency knowledge, and is further developed to neutrosophic soft expert sets by Sahin et al. Adam and Hassan defined multi Q-fuzzy soft sets as an extension to fuzzy soft sets and gave its applications. This article will extend this further by presenting a novel concept of Q-neutrosophic soft expert sets, and define the associated related concepts and basic operations of complement, subset, union, intersection, AND and OR. This novel concept enables the single dimensionality of soft expert sets to be extended to two dimensions. Then, this article constructs an algorithm based on this concept. The following will illustrate the feasibility of the new method by an example. Finally, a comparison of the proposed method to existing methods is furnished to verify the effectiveness of the novel concept.

Authors: Traxler Barbara , Helm Emmanuel , Krauss Oliver , Schuler Andreas , Kueng Josef
Published: August 2018

As an evidence-based business process analysis method, process mining can be used to investigate variations in delivery of care. Existing approaches are only based on one data source. A variety of data sources means different domain languages and understanding, special processes workflows in various organizations, varying documentation with different goals and different designations and varying use of coding systems. This article describes a modular, rule-based information extraction algorithm based on CDA and compares it to a proprietary healthcare reference model approach and a resource-based extraction of healthcare data using the new standard FHIR. All three approaches can be used to derive models to extract clinical and patient pathways. Similarities and differences according to interoperability and process mining tasks are described. It is concluded that standards-based approaches allow for more interoperability and can be used for a wide range of systems to provide process insight, thus facilitating better healthcare management across institutional boundaries.

A ternary micro Mg-0.5Zr-0.4Ce alloy is developed using disintegrated melt deposition method (DMD) followed by hot extrusion. The developed alloy exhibited superior mechanical properties i.e. microhardness, strength and ductility under tensile and compressive loading. In particular, the alloy exhibits excellent ductility (>25%) under both tensile and compressive loading. The mechanisms leading to strengthening and ductilization were examined through microstructural studies involving optical microscope, SEM and XRD texture analysis. Microstructure-property correlation studies are performed to understand these mechanisms.
Effect of Varied Layer-Content/Thickness on Ballistic Performance of a Functionally Graded Al2O3/ZrO2 Material
Authors: Chen Yu Liang , Huang Chin Yu
Published: August 2018

This study compared the ballistic performance of alumina (Al2O3)/ zirconia (ZrO2) functionally graded material (FGM) specimens with various levels of thickness and ZrO2 content and a pure Al2O3 single-layer ceramic composite (PCM). Ballistic tests were conducted with 0.3-inch armor-piercing (AP) projectiles, and finite element code LS-DYNA was used to examine energy absorption, stress distribution, and ceramic cone failure in the specimens. The findings are as follows: First, regarding energy absorption per unit of areal density, the 5% FGMs had the highest ballistic performance, which increased by up to 8%. By contrast, the ballistic performance of the 15% FGMs declined significantly to lower than that of the PCM. Second, the capability of the ceramic cone to withstand stress damage and projectiles was significantly greater in the 5% FGMs than in the 15% FGMs. Third, the wave impedance variations increased with the ZrO2 content in each layer, thereby enhancing the interactions between impact waves and aggravating ceramic damage. Thus, the intensities of transmission and reflection waves in the 15% FGMs increased, thereby causing reductions in its ballistic performance.

Published: August 2018

Abstract. The highly vibrant Asian summer monsoon (ASM) anticyclone plays an important
role in efficient transport of Asian tropospheric air masses to the
extratropical upper troposphere and lower stratosphere (UTLS). In this paper,
we demonstrate long-range transport of Asian trace gases via eddy-shedding
events using MIPAS (Michelson Interferometer for Passive Atmospheric
Sounding) satellite observations, ERA-Interim reanalysis data and the
ECHAM5–HAMMOZ global chemistry-climate model. Model simulations and
observations consistently show that Asian boundary layer trace gases are
lifted to UTLS altitudes in the monsoon anticyclone and are further
transported horizontally eastward and westward by eddies detached from the
anticyclone. We present an event of eddy shedding during 1–8 July 2003 and
discuss a 1995–2016 climatology of eddy-shedding events. Our analysis
indicates that eddies detached from the anticyclone contribute to the
transport of Asian trace gases away from the Asian region to the western Pacific
(20–30∘ N, 120–150∘ E) and
western Africa (20–30∘ N, 0–30∘ E).
Over the last two decades, the estimated frequency of occurrence of eddy-shedding events is ∼68 % towards western Africa and
∼25 % towards the western Pacific. Model sensitivity experiments considering a 10 % reduction in Asian
emissions of non-methane volatile organic compounds (NMVOCs) and nitrogen
oxides (NOx) were performed with ECHAM5–HAMMOZ to understand the impact
of Asian emissions on the UTLS. The model simulations show that transport of
Asian emissions due to eddy shedding significantly affects the chemical
composition of the upper troposphere (∼100–400 hPa) and lower
stratosphere (∼100–80 hPa) over western Africa and the

Abstract. Remote sensing of water vapor in the presence of clouds and precipitation constitutes an important observational gap in the global observing system. We present ground-based measurements using a new radar instrument operating near the 183 GHz H2O line for profiling water vapor inside of planetary-boundary-layer clouds, and develop an error model and inversion algorithm for the profile retrieval. The measurement technique exploits the strong frequency dependence of the radar beam attenuation, or differential absorption, on the low-frequency flank of the water line in conjunction with the radar's ranging capability to acquire range-resolved humidity information. By comparing the measured differential absorption coefficient with a millimeter-wave propagation model, we retrieve humidity profiles with 200 meter resolution and typical statistical uncertainty of 0.6 g/m3 out to around 2 km. The measured spectral variation of the differential absorption coefficient shows good agreement with the model, validating both the measurement method assumptions and the measurement error model. By performing the retrieval analysis on statistically independent data sets corresponding to the same observed scene, we demonstrate the reproducibility of the measurement. An important trade-off inherent to the measurement method between retrieved humidity precision and profile resolution is discussed using an ensemble of ground-based measurements.
On the short-term variability of turbulence and temperature in the winter mesosphere

Published: August 2018

Abstract. Four mesosphere–lower thermosphere temperature and turbulence
profiles were obtained in situ within ∼30 min and over an area of
about 100 by 100 km during a sounding rocket experiment conducted on
26 January 2015 at Poker Flat Research Range in Alaska. In this paper we
examine the spatial and temporal variability of mesospheric turbulence in
relationship to the static stability of the background atmosphere. Using
active payload attitude control, neutral density fluctuations, a tracer for
turbulence, were observed with very little interference from the payload spin
motion, and with high precision (<0.01 %) at sub-meter resolution. The
large-scale vertical temperature structure was very consistent between the
four soundings. The mesosphere was almost isothermal, which means more
stratified, between 60 and 80 km, and again between 88 and 95 km. The
stratified regions adjoined quasi-adiabatic regions assumed to be well mixed.
Additional evidence of vertical transport and convective activity comes from
sodium densities and trimethyl aluminum trail development, respectively,
which were both observed simultaneously with the in situ measurements. We
found considerable kilometer-scale temperature variability with amplitudes of
20 K in the stratified region below 80 km. Several thin turbulent layers
were embedded in this region, differing in width and altitude for each
profile. Energy dissipation rates varied between 0.1 and
10 mW kg−1, which is typical for the
winter mesosphere. Very little turbulence was observed above 82 km,
consistent with very weak small-scale gravity wave activity in the upper
mesosphere during the launch night. On the other hand, above the cold and
prominent mesopause at 102 km, large temperature excursions of +40 to
+70 K were observed. Simultaneous wind measurements revealed extreme wind
shears near 108 km, and combined with the observed temperature gradient,
isolated regions of unstable Richardson numbers (0<Ri<0.25)
were detected in the lower thermosphere. The experiment was launched into a
bright auroral arc under moderately disturbed conditions (Kp∼5).
Basal friction of Fleming Glacier, Antarctica – Part 1: Sensitivity of inversion to temperature and bedrock uncertainty

Published: August 2018

Abstract. Many glaciers in the Antarctic
Peninsula are now rapidly losing mass. Understanding of the dynamics of these
fast-flowing glaciers, and their potential future behaviour, can be improved
through ice sheet modelling studies. Inverse methods are commonly used in ice
sheet models to infer the spatial distribution of a basal friction
coefficient, which has a large effect on the basal velocity and ice
deformation. Here we use the full-Stokes Elmer/Ice model to simulate the
Wordie Ice Shelf–Fleming Glacier system in the southern Antarctic Peninsula.
With an inverse method, we infer the pattern of the basal friction
coefficient from surface velocities observed in 2008. We propose a
multi-cycle spin-up scheme to reduce the influence of the assumed initial
englacial temperature field on the final inversion. This is particularly
important for glaciers like the Fleming Glacier, which have areas of strongly
temperature-dependent deformational flow in the fast-flowing regions.
Sensitivity tests using various bed elevation datasets, ice front positions
and boundary conditions demonstrate the importance of high-accuracy ice
thickness/bed geometry data and precise location of the ice front boundary.
Wind tunnel study on power output and yaw moments for two yaw-controlled model wind turbines
Authors: Bartl Jan , Mühle Franz , Sætran Lars
Published: August 2018

Abstract. In this experimental wind tunnel study the effects of intentional yaw
misalignment on the power production and loads of a downstream turbine are
investigated for full and partial wake overlap. Power, thrust force and yaw
moment are measured on both the upstream and downstream turbine. The
influence of inflow turbulence level and streamwise turbine separation
distance are analyzed for full wake overlap. For partial wake overlap the
concept of downstream turbine yawing for yaw moment mitigation is examined
for different lateral offset positions. Results indicate that upstream turbine yaw misalignment is able to increase
the combined power production of the two turbines for both partial and full
wake overlap. For aligned turbine setups the combined power is increased
between 3.5 % and 11 % depending on the inflow turbulence level and turbine
separation distance. The increase in combined power is at the expense of
increased yaw moments on both the upstream and downstream turbine. For partial
wake overlap, yaw moments on the downstream turbine can be mitigated through
upstream turbine yawing. Simultaneously, the combined power output of the
turbine array is increased. A final test case demonstrates benefits for power
and loads through downstream turbine yawing in partial wake overlap. Yaw
moments can be decreased and the power increased by intentionally yawing the
downstream turbine in the opposite direction.
Engaging in Literacy: Latino Families Speak Up

Family engagement has long been evidenced to contribute to successful educational outcomes. In this qualitative study, we examined the language and literacy perspectives of Latino families of young children. A total of 17 participants who each represented a Latino family from a large urban city participated in focus group interviews. Interviews were analyzed using qualitative methodology. The major themes that emerged from the conversations related to how families define literacy, what literacy looks like in their home, the messages schools give families about literacy, and literacy activities parents would like for schools to promote.
Cortesanía, ética y pedagogía: la huella cívica de Il Cortegiano en la “Égloga II” de Garcilaso de la VegaCourtiership, Ethics, and Pedagogy: Civic Impact of Il Cortegiano in Garcilaso de la Vega's “Eclogue II”
Authors: Lorenzo Javier
Published: August 2018

The “new” Italianate poetry written in Spain by Boscán and Garcilaso de la Vega is inextricably linked, as critics have noted, to their translation of Castiglione's Book of the Courtier. This essay explores the specific impact of Castiglione's book in Garcilaso's “Second Eclogue,” a poem that incorporates the idea of courtiership as ethical training and of the courtier as pedagogue that Castiglione introduces in the last segment of his work. The relationship between courtiership and ethics is critical for understanding Garcilaso's transformation of the Ariostan model (Orlando XLVI.89) that inspires the depiction of the relation between Boscán and the Duke of Alba in the poem. Meanwhile the image of the courtier as pedagogue determines the ideological implications of the contrast that Garcilaso establishes throughout the Eclogue between the duke and the shepherd Albanio.
Un soneto de Cervantes a san FranciscoA Sonnet by Cervantes to St. Francis
Authors: José Palomares
Published: August 2018

Among poetic compositions dedicated to St. Francis of Assisi in Jardín espiritual (1585) of Pedro de Padilla, there is, as is known, a sonnet by Miguel de Cervantes (“Muestra su ingenio el que es pintor curioso”), that has been little studied from a pictorial perspective. Indeed, the inventio of Cervantean composition derives from the Horatian dictum “ut pictura poesis” (Ad Pis., 361), applied to the topic of Deus pictor, but the originality of the laudatio is that does not remark platitudes of the Franciscan hagiography but that urges the saint as a pictura traced by ars divina and, by extension, as a microcosmic imago of Christ. In this paper we focus on the elocutive analysis of the poem, and we try to demonstrate his rhetorical design. The pictorial vocabulary is also related to several texts of the Augustinian Fray Luis de León, whose presence in the poem is postulated as a hypothesis. In the sonnet, in brief, “la historia, la poesía y la pintura simbolizan entre sí” (Persiles, III, 14).
