Q Sensor for the City on the Threshold of Stress
Authors: Layeb Sana , Salem Mohsen Ben Hadj
Published: May 2019

The urban atmosphere evokes several sensory registers that participate in our perception of singular tonalities, of our daily situations. Tunis is, in this chapter, the space-time that would serve as a framework for our hearing. The experimental protocol is threefold. The authors quantify users' feelings through the commented walk method and especially by objective measures of electrodermal activity. The authors conducted in situ metrological work on the sound signal. These measurements were taken using a device “Q sensor.” This device quantifies emotional arousal by measuring electrodermal activity (EDA). The data collected were compared and crossed to identify the links between the architectural configurations of the public space, the sound signals, and the ways in which the feeling of stress appears. The results indicate that urban stress situation seems complex and enjoyable to explore using a multidisciplinary approach. A future direction was presented to the urban settings through the draw on a variety of disciplines, including urban planning, architecture, and psychology.
Space Syntax Beyond Cairo Street Markets
Authors: Arisha Amany Ramadan , El-Moneim Nancy Mostafa Abd
Published: May 2019

Street vending is a growing controversial phenomenon in urban environments. It is a survival strategy and an economic opportunity for countless numbers of marginalized vendors. However, the temporal presence of vendors is portrayed as the source of substantial urban issues, which detract from the quality of the urban public space and the public life of individuals. This chapter aims to propose a practical approach to understand the impact of vendors' temporal presence on the quality of urban space and social life. By space syntax theory, this study utilizes pragmatic methods in the fields of social and human sciences; to analyze the socio-spatial and temporal attributes of the vending phenomenon in relation to urban users' movement in a case study street market at Cairo. The findings introduce a syntactic methodology that highlights the profound relationship between users and informal urban markets to be applied in diverse contexts.
An Argumentative Review Between Urban Morphology and Energy-Efficient Mobility
Authors: Galal Omar M.
Published: May 2019

Urban settlements are recognized in literature to be a significant energy consumer. Among the primary contributors of such consumption is the transportation system. Recent literature that discusses the relation between energy efficient mobility and urban form has been continually branching and growing. However, as it grew, it becomes more specialized, less self-conscious, and to some extent contradicting. After adopting Conzen's approach to urban morphology, this chapter discusses through an argumentative review the relationship between energy efficient mobility and buildings density, land use, and streets networks. In addition to providing a snapshot to critical studies in the last three decades, two arguments are refuted. First, the residents' behavior resulting from socio-economic factors or individuals' choice has more impact than urban morphology characteristics on energy-efficient mobility. Second, morphological characteristics of urban settlements that lead to energy efficient mobility do not vary with the variation of context.
Cairo's Downtown in Narratives
Authors: Aboamer Mougibelrahman , Abdelfattah Dalia
Published: May 2019

Cairo's downtown, through sociopolitical conditions, had been moved from a single city to a hardship one. The authors attempt using a method of multiple readings to provide a new comprehension for the city by using the historical review side by side with several examples from Egyptian literature that describes this dramatic evolution. For this neighborhood, it is considered an active part of Cairo. The period they suggest for scanning the literature begins from Cairo Great Fire in 1952 and its consequences. The year of 1952 and the constitution of the first republic until the dramatic fall of this last by the revolution of January 2011. This chapter aims to articulate the evolution of Downtown Cairo from the singularity to the hardship.
America in the Camera Obscura of Nigerian “Videastes”
Authors: Endong Floribert Patrick C.
Published: May 2019

This chapter argues that, as a popular culture and a reflection of the Nigerian society, Nollywood films remarkably relay the popular myths prevailing in Nigeria. Their representations of foreign countries – notably America – are bound to be both a product and a reflection of popular myths shared by the Nigerian populace on those countries. In tandem with this, Peters Roberts' 30 Days in Atlanta and George U. Kalu's Life is Hard in America, mainly relay most Nigerians' perceptions of America. They present America as a promised land and a heaven, as well as a land of gun-happy people and a country of questionable freedoms. Given the fact that the stereotypes mentioned above similarly abound in many – if not the majority of – Hollywood film productions, one is tempted to argue that many Nollywood film directors' representations of America are not so much different from the ones constructed by their Hollywood counterparts. In other words, it is not incongruent that many Nollywood film directors simply relay Hollywood films' representations of America, thereby naturalizing or endorsing myths such as the American dream.
Image of America in Northern Nigeria Radio-Based Broadcast
Authors: Abdullahi Muhammad Sani
Published: May 2019

This chapter explores popular representations of America in Northern Nigeria radio broadcast using Greetings From America (a call-in program aimed at encouraging Nigerian citizens to seek admission and further their education in American universities) as case study. The chapter is based on a qualitative content analysis of over 15 editions of the program as well as on semi-structured interviews with the News and Current Affairs Manager of Freedom Radio Kano and other relevant informants. The chapter hinges on the propaganda and representation theories. It illustrates how Greeting From America represents a suitable window into America and a platform where Northern Nigerians living and studying in the United States mostly express positive stereotypes of America. The chapter further argues that the program's contents and reception by Northern Nigerians show all the complexity and ambivalence of U.S.'s image in Northern Nigeria. In effect, the impressions of people interviewed in this study coupled with insights drawn from relevant literary sources are sometimes conflicting with the dominantly negative image of the U.S. in Northern Nigeria's popular imagination.
Software Development for Ergonomic Compatibility Assessment of Advanced Manufacturing Technology
Authors: Realyvásquez Arturo , Maldonado-Macías Aide Aracely , Hernández-Escobedo Guadalupe
Published: May 2019

Ergonomic assessment of advanced manufacturing technology (AMT) involves several attributes. Most of these attributes can be assessed only subjectively. Several models have been developed to assess AMT from an ergonomic approach. However, these models have several deficiencies, such as 1) assessment for all alternatives in all their ergonomic attributes should be done in a single period. It lacks time pauses when decision-makings include several decisors and alternatives, 2) every person can access the information and change it, and 3) they lack the propriety of correcting mistakes once users (or decisors) have entered an unwished data. Then, the objective of this research is to develop a software for the ergonomic assessment of AMT that deletes these deficiencies. As method, axiomatic design (AD) was applied jointly with the TRIZ methodology. Software was validated with results of a previous case study. Finally, authors developed a software that removed the deficiencies of previous models.

Published: May 2019

With the growth of software vulnerabilities, the demand for security integration is increasingly necessary to more effectively achieve the goal of secure software development globally. Different practices are used to keep the software intact. These practices should also be examined to obtain better results depending on the level of security. The security of a software program device is a characteristic that permeates the whole system. To resolve safety issues in a software program security solutions have to be implemented continually throughout each web page. The motive of this study is to offer a complete analysis of safety, wherein protection testing strategies and equipment can be categorized into: technical evaluation strategies and non-technical assessment strategies. This study presents high-level ideas in an easy form that would help professionals and researchers solve software security testing problems around the world. One way to achieve these goals is to separate security issues from other enforcement issues so that they can be resolved independently and applied globally.
Types of Focalization in Advertising Narrative
Authors: Özer Deniz
Published: May 2019

In this chapter, the use of the types of focusing in the narrative discourse that direct the perception of the narrative in ads is discussed. In the context of Gerard Genette's focus theory, the study focuses on what are the elements that are prominent in advertisements and which give a perspective to the target audience. The aim of the study is to determine the types of focus used in advertising and the elements that strengthen the advertising narrative. Ads are trying to attract the consumer's attention and are consciously prepared as a form of communication of the contents of the mind that leads to purchase behavior. Therefore, this study to focus on advertising is important to reveal a topic in the advertising literature and to help cover the gap here. The narrative focus in advertising is based on the classification of Genette.
Convergence, Divergence, and Narrative Integration in Public Relations and Advertising
Authors: Akçay Ebru
Published: May 2019

In traditional approaches, public relations and advertising are shown as different practices in terms of their goals and outputs. While management literature draws lines between two practices; cultural approaches assert that public relations and advertising mingle with one another. In this context, this study aims to show how management literature manifests divergence between public relations and advertising while cultural approach suggests that public relations and advertising converge in their objectives and outcomes. In this study, “co-creational perspective” of Carl H. Botan and Maureen Taylor is introduced. In this regard, the study conceptualizes the practices of public relations and advertising as “cultural intermediaries”, a term introduced in Pierre Bourdieu's book titled “Distinction: A Social Critique of the Judgement of Taste.” The study argues that it is more suitable to conceptualize public relations and advertising as creative projects because such conceptualization has a potential to show narrative integration between public relations and advertising.
Adapting Collective Tendencies in Narrative Advertising
Authors: Oralkan Ayca
Published: May 2019

Brands are communication-based strategies where consumer expectations confront with company values, goals and promises. Developing successful branding strategies enables strengthened personal bonds with target groups. Stories have always captivated people and a company can tell its own story to reflect the brand value and the company vision. In the current social media era, narrative advertising has become a favorite tool of communication in reaching the target groups as a persuasion technique by making the audience feel involved and be part of the stories. In this context, collective tendencies are adapted to be the hosting medium for the slogan of the brand or any related information regarding the branding strategies. On the other hand, collective inertia, which develops as a side effect of these cultural tendencies, allows the new approaches as a source of interest if and only if they pass the high threshold. In these circumstances, narrative advertising is one of the most appropriate methods that can be used for a successful marketing strategy to overcome the inertia resistance.

Using IOS in a Collaborative Way
Authors: Nach Hamid , Boudreau Marie-Claude
Published: May 2019

Interorganizational systems (IOS) are information and communication technology-based systems that transcend organizational boundaries. However, their use does not always lead to successful interorganizational collaboration, particularly in settings where significant changes in business processes are needed. The architecture, engineering and construction (AEC) industry offers such a setting, in particular as its stakeholders are encouraged to use of a novel type of interorganizational system known as building information modeling (Building Information Modelling), which can only be successfully used if parties collaborate. This research seeks to uncover what leads to interorganizational collaboration in this particular context. Drawing on rich data from interviews with BIM users involved in interorganizational projects, the authors propose a conceptual model of how interorganizational collaboration unfolds. The authors highlight the central role played by interorganizational infrastructure, collective identity, and IT affordances, on interorganizational collaboration.

Design Patterns Formal Composition and Analysis
Authors: Douibi Halima , Belala Faiza
Published: May 2019

Informal description of design patterns was adopted to facilitate their understanding by software developers. However, these descriptions lead to ambiguities limiting their successful use in real applications. Recently, several formal methods have been employed to guarantee precise specification of design pattern elements without insisting on their behavior. The main goal of this article is to propose a rewriting logic-based framework for enhancing formal description and reasoning on design patterns composition. The proposed model is integrated and executed under Maude using K-Maude tool. It allows first to associate a meta model notation, according to MDA approach, to all design patterns elements and then, a Maude semantic basis for specifying both their structural and dynamic aspects, is given. In particular, it will be shown how the authors' combined modeling approach is exploited for defining a set of operations on patterns, and how it will be used to formal analyze patterns composition.

Published: May 2019

Endoscopic techniques are being used extensively used in the current times for the diagnosis and treatment of numerous intracranial pathologies. Although the morbidity associated with these procedures is lower as compared to other conventional surgical modalities, neuroendoscopic techniques have its own fair share of distinct complications such as bleeding, cerebrospinal fluid leakage, and subdural hematoma. However, certain specific complication fall within the purview of the attending anesthesiologist who should remain vigilant, anticipating these problems to occur and should be well equipped to deal with such contingencies. This review attempts to sensitize the anesthesiologists regarding the well-known as well as rare complications of intracranial neuroendoscopic procedures and to familiarize them with their diverse presentations, preventive strategies, and management protocols.

A aproximação a Pierre Menard: Tradução no primeiro Borges (1925-36)
Authors: Amon Théo
Published: May 2019

Muito debate nos estudos de tradução tem sua origem na obra de Jorge Luis Borges, sendo que geralmente o ponto inicial da discussão é a ficção Pierre Menard, autor do Quixote (1939) e a produção que se seguiu. No entanto, ele já se ocupara intensamente com questões de tradução em seus escritos iniciais, nos quinze anos anteriores àquele grande divisor de águas da sua obra. Entre 1925 e 1936, Borges escreveu um pequeno grupo de ensaios diretamente relacionado à tradução, em grande parte baseados em empreitadas pessoais (uma versão em espanhol da última página do Ulisses, de Joyce) ou traduções de clássicos feitas por terceiros (nomeadamente, as obras de Homero e As mil e uma noites). Este artigo passa em revista esses ensaios iniciais de Borges e esquematiza as principais questões tradutológicas abordadas neles. Busca-se demonstrar que, direta ou indiretamente, as reflexões e contribuições posteriores de Borges sobre questões de tradução já estavam contidas em gérmen na sua primeira produção ensaística.

Feasibility of an Electromyography-Triggered Hand Robot for People After Chronic Stroke
Authors: Kim Grace J. , Taub Michael , Creelman Carly , Cahalan Christine , O’Dell Michael W. , Stein Joel
Published: May 2019

Importance: Effective treatment of the affected hand after stroke is crucial for improved functional independence and recovery.

Objective: To determine the feasibility and clinical utility of an electromyography-triggered hand robot.

Design: Single-group repeated-measures design. Participants completed training 3×/wk for 6 wk. Feasibility data included participant feedback, adverse events, and compliance rates. Upper extremity outcomes were collected at baseline, discharge, and 6-wk follow-up.

Setting: Outpatient clinic.

Participants: Twelve stroke survivors at least 6 mo poststroke living in the community.

Intervention: Eighteen sessions of intensive robotic hand therapy over 6 wk. Each 60-min treatment session was personalized to match the participant’s ability.

Outcomes and Measures: Arm Motor Ability Test (AMAT), Stroke Impact Scale Hand subscale (SIS–H), Stroke Upper Limb Capacity Scale (SULCS), Fugl-Meyer Assessment, Box and Block Test, and dynamometer.

Results: All participants completed the training phase. Mild skin pinching or rubbing at dorsal proximal interphalangeal joint and proximal arm fatigue were the most common adverse events. Improvements in raw scores were achieved from baseline to discharge for all outcome measures, except the SULCS. Participants significantly improved from baseline to discharge on the AMAT and the SIS–H, and improvements were maintained at 6-wk follow-up.

Conclusion and Relevance: Robotic hand training was feasible, safe, and well tolerated. Participants reported and demonstrated improvements in functional use of the affected arm. Thirty percent of participants achieved clinically significant improvements on the AMAT. We recommend further study of the device in a larger study using the AMAT as a primary outcome measure.

What This Article Adds: It is feasible and safe to implement a robotic hand training protocol for people with moderate to severe arm impairment in an outpatient setting. Robotic training may provide a viable option for this group to actively participate in intensive training of the distal hand.
First high-resolution BrO column retrievals from TROPOMI
Authors: Seo Sora , Richter Andreas , Blechschmidt Anne-Marlene , Bougoudis Ilias , Burrows John Philip
Published: May 2019

Abstract. For more than 2 decades, satellite observations from
instruments such as GOME, SCIAMACHY, GOME-2, and OMI have been used for the
monitoring of bromine monoxide (BrO) distributions on global and regional
scales. In October 2017, the TROPOspheric Monitoring Instrument (TROPOMI)
was launched on board the Copernicus Sentinel-5 Precursor platform with the
goal of continuous daily global trace gas observations with unprecedented
spatial resolution. In this study, sensitivity tests were performed to find
an optimal wavelength range for TROPOMI BrO retrievals under various
measurement conditions. From these sensitivity tests, a wavelength range for
TROPOMI BrO retrievals was determined and global data for April 2018 as well
as for several case studies were retrieved. Comparison with GOME-2 and OMI
BrO retrievals shows good consistency and low scatter of the columns. The
examples of individual TROPOMI overpasses show that due to the better signal-to-noise ratio and finer spatial resolution of 3.5×7 km2, TROPOMI BrO
retrievals provide good data quality with low fitting errors and unique
information on small-scale variabilities in various BrO source regions such
as Arctic sea ice, salt marshes, and volcanoes.
Acrylic acid and related dimethylated sulfur compounds in the Bohai and Yellow Seas during summer and winter
Authors: Wu Xi , Li Pei-Feng , Zhang Hong-Hai , Zhu Mao-Xu , Liu Chun-Ying , Yang Gui-Peng
Published: May 2019

Abstract. Spatio-temporal distributions of acrylic acid (AA) and related biogenic sulfur compounds including dimethylsulfide (DMS) and dissolved and total dimethylsulfoniopropionate (DMSPd and DMSPt) were investigated in the Bohai Sea (BS) and the Yellow Sea (YS) during summer and winter. AA and DMS production from DMSPd degradation and AA degradation were studied. Significant seasonal variations of AA and DMS(P) were observed. AA presented similar distributions during summer and winter, that is, relatively high values of AA emerged in the BS and the north YS and concentrations decreased from inshore to offshore areas in the south YS. Due to strong biological production from DMSP and abundant terrestrial inputs from rivers in summer, AA concentrations at surface were higher during summer (30.01 nmol L−1) than during winter (14.98 nmol L−1). The average concentration sequence AA>DMSPt>DMS>DMSPd at transects during summer illustrated particulate DMSP (DMSPp) as a DMS producer and terrestrial sources of AA, whereas the sequence in winter was AA>DMSPt>DMSPd>DMS. High values of AA and DMS(P) were mostly observed in the upper layers with occasional high values at bottom. High AA concentrations in porewater which could be transported into the bottom water might result from the cleavage of intracellular DMSP and reduce bacterial metabolism in sediments. In addition, the degradation/production rates of biogenic sulfur compounds were obviously higher in summer than in winter and the removal of AA was mainly attributed to the microbial consumption. Other sources of AA besides the production from DMSPd was also proved.
Temporal-dependent effects of rainfall characteristics on inter-/intra-event stemflow variability in two xerophytic shrubs
Authors: Yuan Chuan , Gao Guangyao , Fu Bojie , He Daming , Duan Xingwu , Wei Xiaohua
Published: May 2019

Abstract. Stemflow is important for recharging root-zone soil moisture in arid regions. Previous studies have generally focused on stemflow volume, efficiency and influential factors but have failed to depict temporal stemflow processes and quantify their relationships with rainfall characteristics within events, particularly for xerophytic shrubs. Here, we measured the stemflow volume, intensity, duration and time lags to rain events of two xerophytic shrub species (Caragana korshinskii and Salix psammophila) and rainfall characteristics for 54 events in the Liudaogou catchment of the Loess Plateau, China, during the 2014-2015 rainy seasons. The results indicated that stemflow dynamics were well synchronized to rainfall processes. The stemflows of C. korshinskii and S. psammophila had larger average intensities (4.7 ± 1.5 and 4.8 ± 1.6 mm h−1, respectively) than that of rain at the event scale (4.5 ± 1.0 mm h−1), and the stemflows were even more intense (20.3 ± 10.4 and 16.9 ± 8.8 mm h−1, respectively) than that of rain at 10-min intervals (10.9 ± 2.1 mm h−1). The average stemflow durations of C. korshinskii and S. psammophila (3.8 ± 0.8 and 3.4 ± 0.9 h, respectively) were shorter than the rainfall duration (4.7 ± 0.8 h). Tested by a multiple correspondence analysis and stepwise regression, rainfall amount and duration controlled stemflow volume and duration, respectively, at the event scale by linear relationships (p
Sinkholes of the Dead Sea Basin: A Result of Anthropogenic Disturbance to Nature and Sign for More and Greater Hazards
Authors: Salem Hilmi S.
Published: May 2019

Abstract. Over the last few decades, thousands of sinkholes have developed at an increasing pace along the western and eastern shores of the Dead Sea. Recent studies indicate that the number of sinkholes in the Dead Sea Basin (DSB) has reached more than 6,000, with 1–10 m deep and up to 25–30 m in diameter, on average, each. These sinkholes can open-up suddenly and swallow whatever found above them, resulting in an area that looks like an earthquake zone. Sinkholes in the DSB are formed when a subterranean salt layer that once bordered the Dead Sea is dissolved by underground freshwater that follows the migration of the saltwater–freshwater interface, due to receding water level of the Dead Sea. Consequently, large areas of land are subsiding, causing the formation of sinkholes in the region. Also, based on the fact that the Dead Sea’s region is tectonically and seismically active, as it is greatly affected by the Dead Sea Transform Fault System in the region, sinkholes can also be evolved as a result of tectonic and seismic activities. Nevertheless, sinkholes, as geomorphologic features occurring in the DSB, represent the most remarkable evidence of the brutal interferences of humans in the Dead Sea, especially sinkholes started to appear remarkably and frequently in the last half a century only. They present a serious problem to the Dead Sea’s region, as they have led to damages in the infrastructures, and have threatened the safety of humans. Large coastal areas along the Dead Sea shores on both sides of the Sea have already been totally closed to access, because occurrence of more sinkholes is continually developing and rapidly increasing in number. This paper investigates and discusses the occurrence of sinkholes in the Dead Sea Basin, geomorphologically, geologically, seismically, limnologically, and socioeconomically, as well as with respect to the steady decline, at alarming rate, of the Dead Sea’s water level and the continuous shrinkage of its surface area, as the Dead Sea’s water level has been declining, on average, one meter per year just during the last 50 years or so. Also, the sinkholes’ occurrence in the DSB is investigated and discussed, with respect to tectonics and seismicity affecting the region. The results indicate that more attention should be paid to this phenomenon – the rapid and intensive occurrence of sinkholes in the Dead Sea’s region – since it is a serious and dangerous disaster, affecting the Dead Sea Basin itself and its surrounding environment. Unfortunately, this disaster is predominantly caused anthropogenically, as a result of the decline of the Dead Sea’s water level caused by humans’ activities. So, this problem can be avoided or possibly reduced if man would think about nature’s protection rather than about his own interests.
Brief communication: Wind speed independent actuator disk control for faster AEP calculations of wind farms using CFD

Abstract. A simple wind speed independent actuator disk control method is proposed that can be applied to speed up annual energy production calculations of wind farms using Reynolds-averaged Navier–Stokes simulations. The new control method allows the user to simulate the effect of different wind speeds in one simulation by scaling a calibrated thrust coefficient curve, while keeping the inflow constant. Since the global flow is not changed, only the local flow around the actuator disks needs be recalculated from a previous converged result, which reduces the number of required iterations and computational effort by a factor of about 2–3.
De la “industria del piquete” al “paraíso verde”. Turismo y pueblos originarios en un municipio del norte argentino
Authors: Benedetti Cecilia
Published: May 2019

El turismo ha adquirido importancia en las políticas públicas latinoamericanas orientadas a indígenas en las últimas décadas: es propuesto como herramienta para el desarrollo de estos pueblos, en articulación con los discursos vinculados al multiculturalismo. Recuperando los aportes de los estudios antropológicos sobre el Estado y las políticas públicas, este trabajo apunta a reflexionar sobre cómo el fomento al turismo es experimentado y recreado en su circulación por los espacios estatales. Se basa en una investigación de metodología cualitativa desarrollada en un municipio de la región conocida como Chaco Salteño, centrada en la observación participante, la realización de entrevistas, recopilación de fuentes, etc. Abordo el plan de turismo propulsado por la secretaría provincial, enfatizando en las referencias a los modos de visibilización de los pueblos originarios y el lugar de los municipios en su implementación. Luego considero las apropiaciones locales a través de diversas prácticas y discursos de la administración municipal.

The aim of study was to evaluate the effect of intramuscular fat content on physical parameters and proximate composition in musculus longissimus dorsi (MLD) from Mangalitsa breed and Slovak Large White x Mangalitsa crossbreed. In the study, sixteen pigs of Mangalitsa and twenty-two pigs of Slovak Large White x Mangalitsa crossbreed were used. The pigs were reared under intensive condition and all animals were fed ad libitum with complete fattening feed mixture. The fattening period started from 30 kg of live weight. Then the pigs were slaughtered at 100 kg of live weight. Chemical analysis showed that MLD from Mangalitsa had lower protein content, higher moisture content (p <0.05) and higher content of intramuscular fat compared to Slovak Large White x Mangalitsa crossbreed. As regarding the cholesterol content in MLD, no significant differences were found between genotypes, but the cholesterol content was higher in MLD from Mangalitsa than in MLD from crossbreeds. The MLD from Mangalitsa exhibited lower CIE L* (p <0.01) and CIE b* (p <0.01) values 45 min post mortem compared to crossbreeds. Colour parameters increased after 7 days post mortem, which is normal due to the maturing process of the meat. Then the CIE L* value was lower in MLD from Mangalitsa (p <0.01), but CIE a* value was higher in relation to crossbreeds (p <0.05). As regards the Warner-Bratzler shear force, the meat from Mangalitsa was tenderer than in crossbreeds (p <0.05). Intramuscular fat in the meat positively correlated with colour parameter CIE a* (r = 0.324; p <0.05) as well as cholesterol content (r = 0,656; p <0.001). In contrast in the study was found negative correlations between intramuscular fat in meat with moisture content (r = -0.399; p <0.05) and protein content (r = -0.812; p <0.001). It can be concluded that the percentage of intramuscular fat significantly influenced the physical and the chemical parameters of pork. The meat from Mangalitsa is more suitable for production of special meat products (fermented and smoked).
Do Valuation (P/E, ROE and P/BV) Ratios Drive Stock Values? A Case of GCC Countries
Authors: Banerjee Arindam
Published: May 2019

Do valuation ratios predict the future stock prices? Over the decades, researchers have explored data across various global financial markets and across different timelines to seek its unique answer. The results though were not universal, resulted in generating greater interest in the subject. Using valuation ratios as a stock price predictor gained further momentum after Campbell and Shiller’s seminal work involving a century of data sets. In spite of its practical relevance, not much effort was being made to establish the correlation between valuation ratios and stock price of GCC listed companies. This paper attempts to bridge the existing gap by studying 140 publicly listed companies in the six GCC countries namely Qatar, Kuwait, Bahrain, Saudi Arabia, Oman and United Arab Emirates (UAE) using the multiple regression model. The period of study was between 2013-2017. Correlation is established for each of the countries individually, followed by an integrated approach. The independent variables used in the study are Price Earnings Ratio (P/E), Return on Equity (ROE), Price to Book Ratio (P/BV) and Stock Returns being the dependent variable.

Objetivou-se neste estudo avaliar e comparar o uso dos coagulantes sulfato de alumínio e tanino SH no tratamento de efluente gerado em abatedouro avícola utilizando os processos de coagulação/floculação. O resíduo foi coletado em uma agroindústria da região Oeste do Paraná e conduzido ao laboratório para caracterização. Foram testados os dois coagulantes em cinco concentrações diferentes (50; 75; 100; 125 e 150 mg L-1) com três repetições para cada tratamento e os ensaios foram constituídos de tempo de mistura rápida (coagulação) de 2 min com velocidade de agitação de 120 rpm, tempo de mistura lenta (floculação) de 20 min com velocidade de agitação de 30 rpm e tempo de sedimentação de 40 min. As variáveis resposta monitoradas foram: cor, turbidez e demanda química de oxigênio (DQO), obtidas do efluente tratado, além da quantificação da produção de lodo (g L-1). Os melhores resultados para a remoção de cor e turbidez foram obtidos no tratamento com o uso do tanino SH na maior concentração (150 mg L-1) com 98,55 ± 0,35 e 99,43 ± 0,32%, respectivamente, enquanto que a remoção de DQO alcançou maior eficiência com o uso do mesmo coagulante na concentração de 125 mg L-1 (73,29 ± 5,84%). Não foi constatada diferença estatística para a produção de lodo entre os tratamentos aplicados. O coagulante orgânico tanino SH pode ser uma alternativa para o tratamento de efluente de abatedouro avícola pois obteve resultados satisfatórios nas condições testadas, além da produção de um lodo orgânico, que apresenta maior facilidade para disposição final.

Pretreatment of lignocellulosic industrial waste is necessary to promote the cellulose accessibility. Thus, this study evaluated the production of green coconut sugars during pressurized hydrothermal pre-treatment and enzymatic hydrolysis of the pretreated biomass. Pretreatment of the green coconut shell was carried out at 70 °C, 150 bar and water flow rate of 1 mL/min for 4 h. Samples from the system output stream were analyzed by HPLC and Folin Ciocalteu method. The solid fraction was characterized (chemical composition, XRD and FTIR) and subjected to enzymatic hydrolysis. The liquid fractions of pretreatment provided a defined profile of released glucose, xylose, phenolic components and acetic acid over time. After 40 min, most of fermentable sugars were released, forming a liquor with a sugar content above 10 g/L. Post-treated biomass showed a reduction of cellulose (26 % to 17 %) and hemicellulose (23 % to 18 %) and an increase in lignin content (32 % to 44 %). Despite this new chemical composition of the biomass, the pretreated material had lower crystallinity indexes and modifications in its chemical groups. This favored cellulosic conversion from 15 % to 55 %, producing 63.5 % more glucose than the untreated green coconut shell during enzymatic hydrolysis. Thus, the pressurized pre-treatment favored the fermentable sugar production from the green coconut shell, and there is also the possibility of utilizing the sugars present in the pre-treatment liquor.
