Crónica de un Encuentro con los lugares Paciolianos. II International Conference "Before And After Luca Pacioli"
doppio ritratto del poliedrico Luca Pacioli
Authors: Ciocci Argante
Published: November 2017

Questo articolo analizza le ricerche sull'autore del famoso dipinto di Luca Pacioli conservato al Museo di Capodimonte di Napoli. La sua identità non è chiaramente determinata, così come quella della figura a sinistra di Pacioli, che è generalmente considerata il giovane duca Guidobaldo di Montefeltro. Anche la sua personalità è oggetto di studio in quest'opera. Per questo motivo, tutti gli aspetti del dipinto che potrebbero far luce su questo tema sono esaminati con straordinario dettaglio. Tuttavia, non è possibile trarre conclusioni definitive sull'attribuzione del dipinto o sull'identità del giovane ritratto con Pacioli. Proprio il fatto che due persone siano raffigurate insieme ha dato origine al termine "Doppio Ritratto", con cui alcuni autori si riferiscono a questo dipinto.

Per inciso, parlando della fama di cui Luca Pacioli godeva come matematico, tanto da meritarsi un dipinto, fatto singolare all'epoca per un matematico, ricordiamo anche coloro che tentarono di minare questa fama, a partire dal Vasari, che lo accusò di essere un plagiatore, strada seguita da vari altri autori, mentre altri difesero strenuamente il frate di Sansepolcro.

papel de la contabilidad en procesos derivados de irregularidades en la gestión de rentas y reclamación de alcances. La contabilidad del refitor de la Catedral de Toledo Gonzalo Patiño (1582-1583)
Authors: Villaluenga de Gracia Susana
Published: November 2017

ucho se ha hablado del uso de la partida doble y del cargo y data, dos de las formas de llevar la cuenta y razón, según reconocía Diego del Castillo en su obra Tratado de Cuentas (1522). De ellas y de la tercera forma denominada de data y recibo se ha dicho que con sus ventajas e inconvenientes pretendían alcanzar el mismo fin.

Como ya demostramos, en la contabilidad del refitor (el cobrador y pagador de rentas de la mesa capitular) y de otras receptorías de la Catedral de Toledo la partida doble y el cargo y data se utilizaban conjuntamente. La partida doble, sin duda, era el método más avanzado para cuantificar la situación de la receptoría, la relación con terceros y el estado de la caja en cualquier momento y de forma rápida. Sin embargo, tal y como reconoce el jurisconsulto Diego del Castillo, aunque el administrador escribiera el libro donde tuviese lo que recibió y gastó, luego era necesario que los contadores averiguasen la verdad. En este caso el cargo y data era ineludible en la rendición de cuentas del receptor o cajero. En ellos se personificaba la cuenta de caja, siendo deudores y responsables finales del saldo de esta.

En torno al cargo y data, un método más jurídico que contable, se articulaba un sistema de garantías que salvaguardaba los intereses del titular del negocio. Así, tomando como base los registros contables del refitor de la Catedral de Toledo entre 1582 y 1583, este trabajo pretende ser un ejemplo del papel que desempeñaba esta forma de llevar la cuenta en procesos derivados de irregularidades en la gestión de rentas y reclamación de alcances. Esto aunque el método contable utilizado a diario en la oficina fuera la partida doble.
Defensa de la aplicación de la partida doble por un autor del siglo XIX
Authors: Villacorta Hernández Miguel Ángel
Published: November 2017

El artículo muestra los argumentos de una defensa de la partida doble en el siglo XIX. La novedad es encontrar esta defensa dentro de un autor, Manuel Víctor de Christantes y Cañedo, dedicado a reformar la estructura organizativa de la Hacienda Pública española, desde su puesto de Jefe de Sección del Ministerio de Hacienda.

En este trabajo se analizan sus dos principales libros para conocer la verdadera dimensión del autor.

Las principales conclusiones del trabajo serán que estableció, desde su tono humorístico, un conjunto de supuestos prácticos que permitirían la teneduría de libros de forma completa, desde el inicio del ejercicio hasta la elaboración de balances.

Además incorporó la necesidad de llevar libros auxiliares que ayudarían a la teneduría de libros: Libro de aceptaciones, Libro de letras para cobrar, Libro de letras expedidas y el registro de las cuentas Generales.

El autor recomienda expresamente la utilización del método de la partida doble en todas las instituciones públicas. El gran valor de la propuesta es que el autor fue el planificador de la adaptación del sistema contable de la Instrucción de Loterías para que aplicaran partida doble.

Effects of Endwall Fillet and Bulb on the Temperature Uniformity of Pin-Fined Microchannel
Authors: Pan Zhiliang , Li Ping , Li Jinxing , Li Yanping
Published: November 2017

Endwall fillet and bulb structures are proposed in this research to improve the temperature uniformity of pin-fined microchannels. The periodical laminar flow and heat transfer performances are investigated under different Reynolds numbers and radius of fillet and bulb. The results show that at a low Reynolds number, both the fillet and the bulb structures strengthen the span-wise and the normal secondary flow in the channel, eliminate the high temperature area in the pin-fin, improve the heat transfer performance of the rear of the cylinder, and enhance the thermal uniformity of the pin-fin surface and the outside wall. Compared to traditional pin-fined microchannels, the flow resistance coefficient f of the pin-fined microchannels with fillet, as well as a bulb with a 2 μm or 5 μm radius, does not increase significantly, while, f of the pin-fined microchannels with a 10 μm or 15 μm bulb increases notably. Moreover, Nu has a maximum increase of 16.93% for those with fillet and 20.65% for those with bulb, and the synthetic thermal performance coefficient TP increases by 16.22% at most for those with fillet and 15.67% at most for those with bulb. At last, as the Reynolds number increases, heat transfer improvement of the fillet and bulb decreases.
Application of Confined Blasting in Water-Filled Deep Holes to Control Strong Rock Pressure in Hard Rock Mines
Authors: Yang Jingxuan , Liu Changyou , Yu Bin
Published: November 2017

In extra-thick coal seams, mining operations can lead to large-scale disturbances, complex overburden structures, and frequent and strong strata behavior in the stope, which are serious threats to mine safety. This study analyzed the overburden structure and strata behavior and proposed the technique of confined blasting in water-filled deep holes as a measure to prevent strong rock pressure. It found that there are two primary reasons for the high effectiveness of the proposed technique in presplitting hard coal and rock. First, the fracture water enables much more efficient transfer of dynamic load due to its incompressibility. Second, the subsequent expansion of water can further split the rock by compression. A mechanical model was used to reveal how the process of confined blasting in water-filled deep holes presplit roof. Moreover, practical implementation of this technique was found to improve the structure of hard, thick roof and prevent strong rock pressure, demonstrating its effectiveness in roof control.
Testing Extended Accounts in Scheduled Conservation of Open Woodlands with Permanent Livestock Grazing: Dehesa de la Luz Estate Case Study, Arroyo de la Luz, Spain
Authors: Campos Pablo , Mesa Bruno , Álvarez Alejandro , Castaño Francisco , Pulido Fernando
Published: November 2017

Standard Economic Accounts for Agriculture and Forestry do not measure the ecosystem services and intermediate products embedded in the final products recorded, and omit the private non-commercial intermediate products and self-consumption of private amenities. These limitations of the standard accounts are addressed by the extended Agroforestry Accounting System, which is being tested at the publicly-owned Dehesa de la Luz agroforestry estate. The extended accounts simulate conservation forestry of holm oak and cork oak for the current as well as successive rotation cycles during which scheduled conservation of the cultural woodland landscape of the Dehesa de la Luz is carried out, improving the natural physical growth of the firewood and cork. The estimated results for 2014 reveal that private ecosystem services make up 50% of the firewood and grazing products consumed; the private environmental income accounts for 13% of the total private income; and the private environmental asset represents 53% of the total opening capital. The net value added is more than 2.3 times the amount estimated using the standard accounts. The landowner donates intermediate products of non-commercial services at a value of 85 €/ha, which are used to enhance the supply of public products.
Spore Dispersal Patterns of Fusarium circinatum on an Infested Monterey Pine Forest in North-Western Spain
Authors: Dvořák Miloň , Janoš Patrik , Botella Leticia , Rotková Gabriela , Zas Rafael
Published: November 2017

The airborne inoculum of Fusarium circinatum Nirenberg & O’Donnell, the fungal pathogen causing Pine Pitch Canker (PPC), is one of the main means of spread of the disease in forest stands and forest nurseries. Since this world-wide known pathogen was introduced in Europe, its biology in this newly infested area still remains scarcely known. To shed more light on this topic, we set up an experiment on a naturally PPC infested forest of Monterey pine in Galicia (NW Spain) with the following two goals: (i) to describe the seasonal spore dispersal pattern during one year of regular sampling and (ii) to assess the spatial spore dispersal pattern around the infested plot. Portable rotating arm spore traps were used and complemented with meteorological measurements. The abundance of F. circinatum spores in the samples was assessed by quantitative PCR (qPCR) with a hydrolysis probe. The results showed almost permanent occurrence of the air inoculum throughout the whole year, being detected in 27 of the 30 samplings. No clear temporal trends were observed, but a higher air inoculum was favoured by previous lower air temperatures and lower leaf wetness. Conversely, neither rainfall nor air humidity seemed to have any significant importance. The spatial spread of the inoculum was noted to be successful up to a distance of 1000 m in the wind direction, even with winds of just 5 m·s−1. Our study shows that rotating arm spore traps combined with qPCR may be an efficient tool for F. circinatum detection.
The Optimum Slash Pile Size for Grinding Operations: Grapple Excavator and Horizontal Grinder Operations Model Based on a Sierra Nevada, California Survey
Authors: Yoshioka Takuyuki , Sakurai Rin , Kameyama Shohei , Inoue Koki , Hartsough Bruce
Published: November 2017

The processing of woody biomass waste piles for use as fuel instead of burning them was investigated. At each landing of slash pile location, a 132 kW grapple excavator was used to transfer the waste piles into a 522 kW horizontal grinder. Economies of scale could be expected when grinding a larger pile, although the efficiency of the loading operation might be diminished. Here, three piles were ground and the operations were time-studied: Small (20 m long × 15 m wide × 4 m high), Medium (30 × 24 × 4 m), and Large (35 × 30 × 4 m) piles. Grinding the Medium pile was found to be the most productive at 30.65 bone dry tons per productive machine hour without delay (BDT/PMH0), thereby suggesting that there might be an optimum size of slash pile for a grinding operation. Modeling of the excavator and grinder operations was also examined, and the constructed simulation model was observed to well-replicate the actual operations. Based on the modeling, the productivity of grinding at a landing area of 710 m2 of slash pile location was estimated to be 31.24 BDT/PMH0, which was the most productive rate.
Assessment of Flammability of Moroccan Forest Fuels: New Approach to Estimate the Flammability Index
Authors: Essaghi Salaheddine , Hachmi M’hamed , Yessef Mohammed , Dehhaoui Mohammed , El Amarty Fahed
Published: November 2017

A new flammability index (FI) was developed, which integrated two parameters that are highly correlated to fuel moisture content (MC). These parameters are time-to-ignition and flame height. The newly obtained FI-values belong to the variation interval of {0; 20}. In addition to the six flammability classes defined in the earlier work, a seventh class (FI > 16.5) was proposed to include fuel species with a high content of volatile flammable-compounds. Flammability testing and MC measurement were performed at a range of MC obtained through a drying process of samples. As a result, FI was statistically highly correlated with MC for all 13 Moroccan forest fuels tested in this study. Following this, linear regression equations were established to predict the FI-value as a function of MC. Therefore, the classification of flammability would depend on the species as well as the MC-value of the samples and the season in which they were collected.

Authors: Alam Miah , Takao Manabu , Setoguchi Toshiaki
Published: November 2017

The present study reported of the numerical investigation of a high-speed wet steam flow through an asymmetric nozzle. The spontaneous non-equilibrium homogeneous condensation of wet steam was numerically modeled based on the classical nucleation theory and droplet growth rate equation combined with the field conservations within the computational fluid dynamics (CFD) code of ANSYS Fluent 13.0. The equations describing droplet formations and interphase change were solved sequentially after solving the main flow conservation equations. The calculations were carried out assuming the flow two-dimensional, compressible, turbulent, and viscous. The SST k-ω model was used for modeling the turbulence within an unstructured mesh solver. The validation of numerical model was accomplished, and the results showed a good agreement between the numerical simulation and experimental data. The effect of spontaneous non-equilibrium condensation on the jet and shock structures was revealed, and the condensation shown a great influence on the jet structure.
Why Hydrogels Don’t Dribble Water
Authors: Pollack Gerald
Published: November 2017

Hydrogels contain ample amounts of water, with the water-to-solid ratio sometimes reaching tens of thousands of times. How can so much water remain securely lodged within the gel? New findings imply a simple mechanism. Next to hydrophilic surfaces, water transitions into an extensive gel-like phase in which molecules become ordered. This “fourth phase” of water sticks securely to the solid gel matrix, ensuring that the water does not leak out.

Authors: Sun Weiwei , Zhou Yun , Zhang Zhuang , Cao Limin , Chen Weihong
Published: November 2017

With the rapid development of the economy over the past 20 years, the mortality rates from cardiovascular diseases (CVDs) and respiratory diseases (RDs) have changed in China. This study aimed to analyze the trends of mortality rates and years of life lost (YLLs) from CVDs and RDs in the rural and urban population from 1990 to 2015. Using data from Chinese yearbooks, joinpoint regression analysis was employed to estimate the annual percent change (APC) of mortality rates from CVDs and RDs. YLLs due to CVDs and RDs were calculated by a standard method, adopting recommended standard life expectancy at birth values of 80 years for men and 82.5 years for women. Age-standardized mortality rates and YLL rates were calculated by using the direct method based on the Chinese population from the sixth population census of 2010. Age-standardized mortality rates from CVDs for urban residents and from RDs for both urban and rural residents showed decreasing trends in China from 1990 to 2015. Age-standardized mortality rates from CVDs among rural residents remained constant during above period and outstripped those among urban residents gradually. The age-standardized YLL rates of CVDs for urban and rural residents decreased 35.2% and 8.3% respectively. Additionally, the age-standardized YLL rates of RDs for urban and rural residents decreased 64.2% and 79.0% respectively. The age-standardized mortality and YLL rates from CVDs and RDs gradually decreased in China from 1990 to 2015. We observed more substantial declines of the mortality rates from CVDs in urban areas and from RDs in rural areas.
A New Recursive Filtering Method of Terrestrial Laser Scanning Data to Preserve Ground Surface Information in Steep-Slope Areas
Authors: Kim Mi-Kyeong , Kim Sangpil , Sohn Hong-Gyoo , Kim Namhoon , Park Je-Sung
Published: November 2017

Landslides are one of the critical natural hazards that cause human, infrastructure, and economic losses. Risk of catastrophic losses due to landslides is significant given sprawled urban development near steep slopes and the increasing proximity of large populations to hilly areas. For reducing these losses, a high-resolution digital terrain model (DTM) is an essential piece of data for a qualitative or a quantitative investigation of slopes that may lead to landslides. Data acquired by a terrestrial laser scanning (TLS), called a point cloud, has been widely used to generate a DTM, since a TLS is appropriate for detecting small- to large-scale ground features on steep slopes. For an accurate DTM, TLS data should be filtered to remove non-ground points, but most current algorithms for extracting ground points from a point cloud have been developed for airborne laser scanning (ALS) data and not TLS data. Moreover, it is a challenging task to generate an accurate DTM from a steep-slope area by using existing algorithms. For these reasons, we developed an algorithm to automatically extract only ground points from the point clouds of steep terrains. Our methodology is focused on TLS datasets and utilizes the adaptive principal component analysis–triangular irregular network (PCA-TIN) approach. Our method was applied to two test areas and the results showed that the algorithm can cope well with steep slopes, giving an accurate surface model compared to conventional algorithms. Total accuracy values of the generated DTMs in the form of root mean squared errors are 1.84 cm and 2.13 cm over the areas of 5252 m2 and 1378 m2, respectively. The slope-based adaptive PCA-TIN method demonstrates great potential for TLS-derived DTM construction in steep-slope landscapes.
Molecular-Targeted Therapies for Epidermal Growth Factor Receptor and Its Resistance Mechanisms
Authors: Yamaoka Toshimitsu , Ohba Motoi , Ohmori Tohru
Published: November 2017

Cancer therapies targeting epidermal growth factor receptor (EGFR), such as small-molecule kinase inhibitors and monoclonal antibodies, have been developed as standard therapies for several cancers, such as non-small cell lung cancer, colorectal cancer, pancreatic cancer, breast cancer, and squamous cell carcinoma of the head and neck. Although these therapies can significantly prolong progression-free survival, curative effects are not often achieved because of intrinsic and/or acquired resistance. The resistance mechanisms to EGFR-targeted therapies can be categorized as resistant gene mutations, activation of alternative pathways, phenotypic transformation, and resistance to apoptotic cell death. Analysis of the processes that modulate EGFR signal transduction by EGFR-targeted inhibitors, such as tyrosine kinase inhibitors and monoclonal antibodies, has revealed new therapeutic opportunities and has elucidated novel mechanisms contributing to the discovery of more effective anticancer treatments. In this review, we discuss the roles of EGFR in cancer development, therapeutic strategies for targeting EGFR, and resistance mechanisms to EGFR-targeted therapies, with a focus on cancer therapies for individual patients.
Anisotropic Failure Strength of Shale with Increasing Confinement: Behaviors, Factors and Mechanism

under different confinements, different combinations of

may have various types of influences on the minimum failure strength with the increasing confinement; therefore, different types of anisotropic behaviors occur for different shale specimens as the confinement increases. These findings are very important to understand the stability of wellbore and underground tunneling in the shale rock mass, and should be helpful for further studies on hydraulic fracture propagations in the shale reservoir.

Published: November 2017

A novel metal matrix composite CrMnFeCoNi with Y2O3 as reinforcement phase was designed and manufactured by mechanical alloying and spark plasma sintering. After sintering at 900 °C for 5 min, the microstructure consisted of a FCC matrix and Y2O3 nanoparticles. The addition of 0.25 wt % Y2O3 increased the room temperature tensile strength of the CrMnFeCoNi base from 868 MPa to 1001 MPa, while the mechanical properties of the addition of 0.5 wt % Y2O3 composite decreased. In the meantime, the addition of Y2O3 had no significant influence on the coefficient of friction, while the addition of 0.25 wt % Y2O3 composite shows excellent wear-resistance.
The Untidy Playground: An Irish Congolese Case Study in Sonic Encounters with the Sacred Stranger
Authors: Phelan Helen
Published: November 2017

This paper explores the proposal that music, and particularly singing, has unique properties that render it amenable to encounters with “the other” or the sacred stranger. Drawing on the deconstructionist works of Kristeva and Derrida, as well as the postmodern hermeneutics of Kearney and Caputo, it explores current debate concerning the nature of “the sacred” in contemporary life and the erosion of the theistic/atheistic divide, while proposing a deepening of the debate through the inclusion of the performative. As philosophical and theological discourses embrace this aporia, it does so against the backdrop of unprecedented human migration. The concomitant cultural and social disruption throws up new questions around the nature and experience of religion, spirituality and the sacred. This paper explores these questions in the context of a Congolese choir called Elikya, which was established by a group of asylum seekers in Limerick city, Ireland, in 2001. In tracking the musical life of this choir over the last decade and a half, including two musical recordings and numerous liturgical, religious and secular performances, it suggests that the sonic world of the choir both performs and transcends these descriptors. Using a three-fold model of context, content and intent, the paper concludes that musical experiences such as those created by Elikya erode any easy divisions between the religious and the secular or the liturgical and the non-liturgical and provide sonic opportunities to encounter the sacred stranger in the untidy playground of creative chaos.
I-DWRL: Improved Dual Wireless Radio Localization Using Magnetometer
Authors: Aziz Abdul , Kumar Ramesh , Joe Inwhee
Published: November 2017

In the dual wireless radio localization (DWRL) technique each sensor node is equipped with two ultra-wide band (UWB) radios; the distance between the two radios is a few tens of centimeters. For localization, the DWRL technique must use at least two pre-localized nodes to fully localize an unlocalized node. Moreover, in the DWRL technique it is also not possible for two sensor nodes to properly communicate location information unless each of the four UWB radios of two communicating sensor nodes cannot approach the remaining three radios. In this paper, we propose an improved DWRL (I-DWRL) algorithm along with mounting a magnetometer sensor on one of the UWB radios of all sensor nodes. This addition of a magnetometer helps to improve DWRL algorithm such that only one localized sensor node is required for the localization of an unlocalized sensor node, and localization can also be achieved even when some of the four radios of two nodes are unable to communicate with the remaining three radios. The results show that with the use of a magnetometer a greater number of nodes can be localized with a smaller transmission range, less energy and a shorter period of time. In comparison with the conventional DWRL algorithm, our I-DWRL not only maintains the localization error but also requires around half of semi-localizations, 60% of the time, 70% of the energy and a shorter communication range to fully localize an entire network. Moreover, I-DWRL can even localize more nodes while transmission range is not sufficient for DWRL algorithm.
A New Low Complexity Angle of Arrival Algorithm for 1D and 2D Direction Estimation in MIMO Smart Antenna Systems
Authors: Al-Sadoon Mohammed , Ali Nazar , Dama Yousf , Zuid Abdulkareim , Jones Stephen , Abd-Alhameed Raed , Noras James
Published: November 2017

This paper proposes a new low complexity angle of arrival (AOA) method for signal direction estimation in multi-element smart wireless communication systems. The new method estimates the AOAs of the received signals directly from the received signals with significantly reduced complexity since it does not need to construct the correlation matrix, invert the matrix or apply eigen-decomposition, which are computationally expensive. A mathematical model of the proposed method is illustrated and then verified using extensive computer simulations. Both linear and circular sensors arrays are studied using various numerical examples. The method is systematically compared with other common and recently introduced AOA methods over a wide range of scenarios. The simulated results show that the new method has several advantages in terms of reduced complexity and improved accuracy under the assumptions of correlated signals and limited numbers of snapshots.
Low-Carbon Planning and Design in B&R Logistics Service: A Case Study of an E-Commerce Big Data Platform in China
Authors: Ji Shoufeng , Sun Qi
Published: November 2017

The concept of sustainable development requires us to explore a completeness model of low carbon transport and service in the light of the advancement of changes in world cooperation policy. Various kinds of carbon constraints not only limit emissions of contaminants from E-commerce Enterprise of different countries, but they also ensure the market activity around the Belt and Road, so as to avoid the implementation reducing the company’s profits significantly. This paper discusses of the strictest periodic low-carbon constraints_(PLC) and the expansion of the mainstream with three relatively weak attributes—cumulative_(CLC), full cycle_(FCLC), and volatility_(VLC)—taking into account the offline delivery of lead time and the online relationship between supply and demand on the platform. We have established four decision models with different carbon confinement intensities and inferred the impact of more detailed carbon constraints on E-commerce delivery strategies. The appropriate operational decisions, under a wide spectrum of carbon constraints, help e-companies develop scientific delivery plans, and provide some inspiration for the promotion of low carbon economy system construction and environmental significance.
Fostering Multi-Functional Urban Agriculture: Experiences from the Champions in a Revitalized Farm Pond Community in Taoyuan, Taiwan
Authors: Chou Rung-Jiun , Wu Chen-Ting , Huang Feng-Tzu
Published: November 2017

Urban agriculture (UA) with its multi-functional roles has recently become a globally important topic, as it is considered as an approach to address the emerging challenges to societies seeking greater sustainability. In Taiwan, the Hakka community of Gaoyuan in Taoyuan City, where a traditional farm pond was recently transformed into a public, multi-functional UA resource, is widely regarded as the first successful bottom-up, community-led, farm-pond-based UA in Taiwan, yet its actual performance is rarely explored in any depth. Little work has been done to provide details on the socio-ecological benefits of UA in the community redevelopment process. Through in-depth interviews, fieldwork, and participant observation, this specific qualitative study aims to explore the community champions’ experiences in the transformation leading to a revitalized community. First, by linking nearby nature to people, a green network of diverse spaces, low-impact landscaping, and an agricultural-community-like pondscape, the specific landscape character that makes UA in Gaoyuan distinctive is formed. Second, through active engagement, participation, and the agency of local people, the UA implementation process features cooperative working, mutual learning, and experience-sharing. Third, UA plays a crucial role in building social cohesion that promotes people’s participation in community affairs, and strengthens the community’s social network, which involves agricultural life, crop production, the ecological environment, and community care. It is revealed that the farm-pond-based UA with its multi-functional roles acts as a catalyst for the Gaoyuan community’s progress toward sustainability. The desired end-state of the agricultural landscape, as a synthesis of natural features and human interventions, is a more sustainable, characteristic, well-maintained and united place to fulfill people’s needs and enhance people’s overall health and well-being.
Cats and Carbohydrates: The Carnivore Fantasy?
Authors: Verbrugghe Adronie , Hesta Myriam
Published: November 2017

The domestic cat’s wild ancestors are obligate carnivores that consume prey containing only minimal amounts of carbohydrates. Evolutionary events adapted the cat’s metabolism and physiology to this diet strictly composed of animal tissues and led to unique digestive and metabolic peculiarities of carbohydrate metabolism. The domestic cat still closely resembles its wild ancestor. Although the carnivore connection of domestic cats is well recognised, little is known about the precise nutrient profile to which the digestive physiology and metabolism of the cat have adapted throughout evolution. Moreover, studies show that domestic cats balance macronutrient intake by selecting low-carbohydrate foods. The fact that cats evolved consuming low-carbohydrate prey has led to speculations that high-carbohydrate diets could be detrimental for a cat’s health. More specifically, it has been suggested that excess carbohydrates could lead to feline obesity and diabetes mellitus. Additionally, the chances for remission of diabetes mellitus are higher in cats that consume a low-carbohydrate diet. This literature review will summarise current carbohydrate knowledge pertaining to digestion, absorption and metabolism of carbohydrates, food selection and macronutrient balancing in healthy, obese and diabetic cats, as well as the role of carbohydrates in prevention and treatment of obesity and diabetes mellitus.
Major Events Programming in a City: Comparing Three Approaches to Portfolio Design
Authors: Antchak Vladimir , Pernecky Tomas
Published: November 2017

Event portfolio design is increasingly important from both academic and industry perspectives. The purpose of this article is to discuss and conceptualize the strategic process of event portfolio planning and development in different urban contexts in New Zealand. A qualitative multiple
case study was conducted in three cities: Auckland, Wellington, and Dunedin. Primary data were collected by interviewing city event planners from city councils and relevant council controlled organizations. Secondary data were obtained by the analysis of the relevant documents, including city
event policies and strategies, annual reports, statements, and activity plans. Thematic analysis revealed the existence of distinctive portfolio approaches in the studied cases, which can be compared and differentiated by applying the following parameters: Formality, Intentionality, Directionality,
and Rhythmicity. Together, these parameters represent a "built-in equalizer" that can be used to balance the opposing values of diverse approaches and adjust them within current city objectives. The article provides a rich and broad context, which enables an understanding of the strategic
nature of event portfolios and their implementation within a wider city development agenda.
The Practices of the Eventful City: The Case of Incubate Festival
Authors: Simons Ilja
Published: November 2017

The use of events as policy tools in cities has become widely recognized. However, most studies concerning this topic do not capture the complex interrelationships that underpin the development of an eventful city. This study applies a practice approach, in order to analyze the dynamics
of the eventful city practice. It places the urban event practice centrally in the analysis and focuses on the actual "sayings and doings" of the practice. The event practice of the 2015 Incubate festival in Tilburg, the Netherlands, is analyzed by means of ethnographic methods, including
participant observation and interviews. Incubate illustrates how both the city and the event are performed within the practice: the event shapes the city and the city shapes the event. However, the integration of the festival into alternative spaces in the city means that it does not increase
the visibility of Tilburg, and therefore fails to deliver value to its eventful city policy.
Animation or Denigration? Using Urban Public Spaces as Event Venues
Authors: Smith Andrew
Published: November 2017

City events are increasingly staged outside purpose-built venues in urban public spaces. Parks, streets, and squares have always been used for civic events, but there is now pressure to use them for a wider range of occasions including large-scale, ticketed events. This article identifies
why this trend is occurring and outlines the implications for public spaces. The use of London's parks as venues for music festivals, elite sport events, and trade exhibitions is the main focus of the article. These events challenge the established functions and meanings of public parks. Noted
positive effects include challenging the rather stiff character of Victorian parks and encouraging different users/uses. However, ticketed events restrict access to parks and various processes currently afflicting urban public spaces—privatization, commercialization, and securitization—are
exacerbated when parks are used as event venues. These effects are often dismissed as inherently temporary, but staging events can have enduring effects on the provision and accessibility of public space. The article concludes that staging events in public spaces is increasingly driven by
a neoliberal agenda, with place marketing and revenue generation key priorities. This needs to be more fully acknowledged in analyses of the eventful city.
Eventful Cities as Global Innovation Catalysts: The Sónar Festival Network
Authors: Colombo Alba , Richards Greg
Published: November 2017

As the economy becomes more globalized, a growing number of events are exerting an influence on activity and innovation globally in different fields. Therefore, we argue that "eventful cities" can act as important catalysts for eventfulness in other places as well. This article analyzes
the case of the Sónar electronic music festival, an event that originated in Barcelona, Spain, but which now runs different editions in many cities worldwide. This empirical study of the innovation capacity of a cultural event examines how a locally based music festival has transformed
itself by using the global "space of flows" to influence the local "space of places." The Sónar Festival has turned itself into a relational hub in a global cultural network, using stylistic innovations to link geographically dispersed nodes in order to create new products, open up
new markets, and strengthen its own position as a global source of eventfulness.
Possible Range of Viscosity Parameters to Trigger Black Hole Candidates to Exhibit Different States of Outbursts
Authors: Mondal Santanu , Chakrabarti Sandip K. , Nagarkoti Shreeram , Arévalo Patricia
Published: November 2017

In a two component advective flow around a compact object, a high-viscosity Keplerian disk is flanked by a low angular momentum and low-viscosity flow that forms a centrifugal, pressure-supported shock wave close to the black hole. The post-shock region that behaves like a Compton cloud becomes progressively smaller during the outburst as the spectra change from the hard state (HS) to the soft state (SS), in order to satisfy the Rankine–Hugoniot relation in the presence of cooling. The resonance oscillation of the shock wave that causes low-frequency quasi-periodic oscillations (QPOs) also allows us to obtain the shock location from each observed QPO frequency. Applying the theory of transonic flow, along with Compton cooling and viscosity, we obtain the viscosity parameter

required for the shock to form at those places in the low-Keplerian component. When we compare the evolution of

for each outburst, we arrive at a major conclusion: in each source, the advective flow component typically requires an exactly similar value of

when transiting from one spectral state to another (e.g., from HS to SS through intermediate states and the other way around in the declining phase). Most importantly, these

values in the low angular momentum advective component are fully self-consistent in the sense that they remain below the critical value

required to form a Keplerian disk. For a further consistency check, we compute the

of the Keplerian component, and find that in each of the objects,

Global Solar Magnetic Field Organization in the Outer Corona: Influence on the Solar Wind Speed and Mass Flux Over the Cycle
Authors: Réville Victor , Brun Allan Sacha
Published: November 2017

The dynamics of the solar wind depends intrinsically on the structure of the global solar magnetic field, which undergoes fundamental changes over the 11-year solar cycle. For instance, the wind terminal velocity is thought to be anti-correlated with the expansion factor, a measure of how the magnetic field varies with height in the solar corona, usually computed at a fixed height (

, the source surface radius that approximates the distance at which all magnetic field lines become open). However, the magnetic field expansion affects the solar wind in a more detailed way, its influence on the solar wind properties remaining significant well beyond the source surface. We demonstrate this using 3D global magnetohydrodynamic (MHD) simulations of the solar corona, constrained by surface magnetograms over half a solar cycle (1989–2001). A self-consistent expansion beyond the solar wind critical point (even up to

) makes our model comply with observed characteristics of the solar wind, namely, that the radial magnetic field intensity becomes latitude independent at some distance from the Sun, and that the mass flux is mostly independent of the terminal wind speed. We also show that near activity minimum, the expansion in the higher corona has more influence on the wind speed than the expansion below

Electron-capture and Low-mass Iron-core-collapse Supernovae: New Neutrino-radiation-hydrodynamics Simulations
Authors: Radice David , Burrows Adam , Vartanyan David , Skinner M. Aaron , Dolence Joshua C.
Published: November 2017

We present new 1D (spherical) and 2D (axisymmetric) simulations of electron-capture (EC) and low-mass iron-core-collapse supernovae (SN). We consider six progenitor models: the ECSN progenitor from Nomoto; two ECSN-like low-mass low-metallicity iron-core progenitors from A. Heger (2016, private communication); and the 9, 10, and 11

(zero-age main-sequence) progenitors from Sukhbold et al. We confirm that the ECSN and ESCN-like progenitors explode easily even in 1D with explosion energies of up to a 0.15 Bethes (

), and are a viable mechanism for the production of very-low-mass neutron stars. However, the 9, 10, and 11

progenitors do not explode in 1D and are not even necessarily easier to explode than higher-mass progenitor stars in 2D. We study the effect of perturbations and of changes to the microphysics and we find that relatively small changes can result in qualitatively different outcomes, even in 1D, for models sufficiently close to the explosion threshold. Finally, we revisit the impact of convection below the protoneutron star (PNS) surface. We analyze 1D and 2D evolutions of PNSs subject to the same boundary conditions. We find that the impact of PNS convection has been underestimated in previous studies and could result in an increase of the neutrino luminosity by up to factors of two.
Formation of Anionic C, N-bearing Chains in the Interstellar Medium via Reactions of H− with HCxN for Odd-valued x from 1 to 7
Authors: Gianturco F. A. , Satta M. , Yurtsever E. , Wester R.
Published: November 2017

We investigate the relative efficiencies of low-temperature chemical reactions in the interstellar medium with H− anion reacting in the gas phase with cyanopolyyne neutral molecules, leading to the formation of anionic

linear chains of different lengths and of H2. All the reactions turn out to be without barriers, highly exothermic reactions that provide a chemical route to the formation of anionic chains of the same length. Some of the anions have been observed in the dark molecular clouds and in the diffuse interstellar envelopes. Quantum calculations are carried out for the corresponding reactive potential energy surfaces for all the odd-numbered members of the series (x = 1, 3, 5, 7). We employ the minimum energy paths to obtain the relevant transition state configurations and use the latter within the variational transition state model to obtain the chemical rates. The present results indicate that at typical temperatures around 100 K, a set of significantly larger rate values exists for x = 3 and x = 5, while the rate values are smaller for CN− and

. At those temperatures, however, all the rates turn out to be larger than the estimates in the current literature for the radiative electron attachment (REA) rates, thus indicating the greater importance of the present chemical path with respect to REA processes at those temperatures. The physical reasons for our findings are discussed in detail and linked with the existing observational findings.
