Une migration instrumentalisée : politiques étatiques et pratiques institutionnelles lors du départ des Grecs d’Égypte (1945-1961)
Authors: Dalachanis Angelos
Published: June 2019

Les Grecs d’Égypte constituaient la colonie étrangère la plus nombreuse en Égypte le long du xixe siècle et jusqu’au milieu du xxe. L’historiographie a longtemps attribué leur départ à la crise de Suez et aux mesures de nationalisation d’entreprises décidées par Gamal Abdel Nasser au début des années 1960. Cet article montre que cette émigration n’est pas le seul fait d’initiatives individuelles ou de la politique nationaliste égyptienne, mais qu’elle a été l’objet de plus longs projets des institutions de la colonie grecque et de l’État grec ainsi que des organisations internationales qui, pour des raisons politiques qui leur sont propres, l’ont promue.
The Interactions Between Cultural Intelligence, Job Burnout, and Task Performance of Expatriates
Authors: Doğru Çağlar
Published: June 2019

In this chapter, cultural intelligence, one of the most crucial capabilities of employees for overcoming the cultural obstacles of different countries, is figured out in depth. This is attained by checking out the relationships between cultural intelligence, job burnout and task performance of expatriates who are employees sent by their company to a host country for a period. Since expatriates are the employees who face actual barriers in adapting and living in different cultures, a quantitative research was conducted among 156 expatriates working at the marketing department of different multinational companies, operating in Turkey. According to the results, expatriates with high cultural intelligence face burnout less at the workplace. Moreover, task performance of these employees tends to increase because of their cultural intelligence. Consequently, with the help of this chapter, a paramount empirical study on cultural intelligence and its correlates is added to the literature.

Published: June 2019

Biodiversity is severely affected by the various anthropogenic activities. Humans depend on natural resources for survival. The resources include food, clean drinking water, timber for construction, fibers for clothing, natural gas, and coal for industries. The biggest threat to the atmosphere is pollutants caused by different human activities. The earth atmosphere is a layer of gases that surrounds the planet and allows us to breathe and live. The atmosphere is made up of Nitrogen, Oxygen, and others types of gases. This mixture of gases is known as air. Air pollution results from a variety of pollutants like NO2, SO2, CO, CFCs, and Ozone. Carbon dioxide, which is a greenhouse gas, warms the earth. This chapter will explore the effects of atmospheric pollutants on biodiversity due to various types of adulterants in the atmosphere and its effects on the survival of earth. Additionally, it will sketch various tools that can reduce these harmful activities.

Food insecurity is a recurrent condition in which members of a household do not have enough food to cover their nutritional needs; this condition contributes to increasing social vulnerability of those affected. In Peru, there are more than 9 million people who suffer this condition, which generates malnutrition and anemia, mostly in children. On the other hand, the waste of food is associated with production the large amounts of greenhouse gas emissions that affect global warming. According to reports in Peru, 20% of what is food produced becomes waste. This scenario in terms of food for Peruvians represents 3 billion calories in wasted food that could feed 2 million people. The Peruvian Food Bank manages food donations, ensuring this food can reach people in need through humanitarian aid entities. This applied research work uses the tools of operations research to determine a solution to the problem of maximizing the combination of food orders to be distributed based on their total nutritional value to the beneficiaries, seeking maximum coverage and minimum logistic costs.
Data Science and Knowledge Analytic Contexts on IoE Data for E-BI Application Case
Authors: Mishra Nilamadhab
Published: June 2019

The progressive data science and knowledge analytic tasks are gaining popularity across various intellectual applications. The main research challenge is to obtain insight from large-scale IoE data that can be used to produce cognitive actuations for the applications. The time to insight is very slow, quality of insight is poor, and cost of insight is high; on the other hand, the intellectual applications require low cost, high quality, and real-time frameworks and algorithms to massively transform their data into cognitive values. In this chapter, the author would like to discuss the overall data science and knowledge analytic contexts on IoE data that are generated from smart edge computing devices. In an IoE-driven e-BI application, the e-consumers are using the smart edge computing devices from which a huge volume of IoE data are generated, and this creates research challenges to traditional data science and knowledge analytic mechanisms. The consumer-end IoE data are considered the potential sources to massively turn into the e-business goldmines.

Authors: Kavitha V.  , Vimaladevi M.  , Manavalasundaram V. K.
Published: June 2019

Agriculture is one particular sector that is prone to different problems. In India the situation of farmers is even worse. They face a lot of issues ranging from inadequate rainfall, temperature-related issues, crop diseases, animal issues, etc. It is quite a complex job for a farmer to analyze and ascertain climatic, soil, and other vital conditions for the growth of the crop every day. Also, for a farmer to predict the oncoming rainfall and its pattern and to judge suitable soil and ambient environment for crop growth requires historical records of the crop growth data of that particular region of cultivation. This chapter addresses the issues in handling big data related to agri-sector issues. Finally, a prototype model for collecting information from the IoT devices that will be placed in fields to alert the farmers about plant disease infection risk is presented.

Authors: Mironyuk Sergey Stepanovich , Smirnov Alexander , Sokolov Alexander V. , Proshkin Yuri
Published: June 2019

It is known that in the case of technology use of the supplementary lighting, an irradiation spectral composition heavily influences the effectiveness of the photosynthesis processes, development and productivity of vegetable crops. Hence, the definition of general points at development and projecting of modern phyto-irradiators is one of high-priority tasks in techniques development for plants growing in conditions of protected ground. The research is aimed at reviewing and assessing the effectiveness of existing sources of illumination used in modern systems of supplementary lighting and at deduction of general points of development and projecting of phyto-irradiators based on results of laboratory investigations with the use of modern digital technologies of monitoring and data analysis. The results of the comparative tests of light emitting diodes-based phyto-irradiators showed that the energy consumption per product kilogram is less than in the case of LED-irradiators. Based on the research results, general points were deducted for use at development of modern LED-phyto-irradiators.
Energy-Saving Technologies for Pre-Sowing Seed Treatment in a Magnetic Field
Authors: Kozyrskiy Volodymyr , Savchenko Vitaliy , Sinyavsky Oleksandr , Bunko Vasyl
Published: June 2019

The purpose of the research was to establish the mechanism of the magnetic field impact on seeds to determine the most effective mode of pre-sowing treatment of seeds in a magnetic field and design parameters of the device for magnetic treatment of seeds. It is established that under the influence of a magnetic field the rate of chemical reactions occurring in plant cells is accelerated, solubility of salts and acids increases, and permeability of cell membranes accelerates the diffusion of molecules and ions through them. This leads to an increase in the concentration of ions in the cell and oxygen molecules and the growth of water absorption of seeds. Pre-sowing seed treatment promotes increased germination by 25-40%, and germination by 30 - 35%. The most effective pre-sowing treatment of seeds in a magnetic field is a magnetic induction of 0.065 Tl with four reversal magnetization, a pole division of 0.23 m and a seed movement speed of 0.4 m/s. With this mode of treatment, crop yields increase by 20–25%.

Published: June 2019

Solving the problem of increasing plant resistance, the development of environmentally-friendly technologies is particularly important, which also contribute to the reduction of resource costs for production and load on the environment. The research results indicate a positive effect from the treatment of plants and seeds with electrochemically activated (ECA) water, electric fields, and impulse pressure (IP). Pre-sowing treatment of seeds with ECA water increases the germination rate and seed germination energy, improves the development of plants, improves morphological parameters, etc. The reactions of economically dangerous pests and causative agents of infectious plant diseases to the use of ECA water are identified. The combination of pre-sowing seed treatment with the treatment of vegetative plants provides the highest possible result.

Authors: Panchenko Vladimir , Kharchenko Valeriy
Published: June 2019

This chapter discusses the simulation of solar photovoltaic thermal modules of planar and concentrator structures in computer-aided design systems KOMPAS 3D and finite element analysis ANSYS. To create photovoltaic thermal modules, a method for designing their three-dimensional models in the computer-aided design system has been developed. To study the thermal regimes of the created three-dimensional models of modules, a method has been developed for visualizing thermal processes, coolant velocity, and flow lines of a cooling agent in a finite element analysis system. As a result of calculations in the finite element analysis system using the developed method, conclusions can be drawn about the feasibility of the design created with its further editing, visualization of thermal fields, and current lines of the radiator cooling agent. As an illustration of the simulation results, a three-dimensional model of a photovoltaic thermal planar roofing panel and an optimized three-dimensional model of a photodetector of a solar concentrator photovoltaic thermal module are presented.

Reflection of Ideology and Politics in Travel Writing
Authors: Liashuk Xenia
Published: June 2019

The chapter focuses on the ways in which politics and ideology are incorporated into travel writing. The analysis of two travel books involving the U.S. American and the Soviet Russian cultures, namely Little Golden America (One-Storied America, 1937) by Soviet humorists Ilf and Petrov, and A Russian Journal (1948) by American novelist John Steinbeck, reveals the two factors of importance influencing the depiction of politics and ideology in travel writing, namely the authors' identity including their personal ideologies and the polarity of bilateral political and ideological relations between the nations concerned. These two factors predetermine the specific issues of political and ideological nature described and explained in travel writing and the angle and character of their interpretation and evaluation by the authors.
Negative Impact of Ideology in Albanian Literature
Authors: Kerbizi Marisa , Macaj Edlira Tonuzi
Published: June 2019

Ideology as a form of ideas and as a practical tool with determinative purposes in certain circumstances may become very influential and risky, too. Albanian literature, as one of the East Bloc countries where communism was installed as a political system after the Second World War, severely suffered the ideology consequences in art. The purpose of this research is to focus on some problems related to the limitations, restrictions, deviation, regression created by ideology in literature. Concrete case studies will complete the theoretical frame through the analytical, historical, aesthetical, and interpretative approach. The hypothesis sustains the idea that the political ideology of the Albanian dictatorial system has found many ways to damage the most representative authors and their artistic works of Albanian literature. The ideology claimed “the compulsory educational system” by interfering in the school textbooks, by excluding several authors from those textbooks, by denying their inclusion or the right for publication, or even by eliminating them physically.
Enhancing Disability Determination Decision Process Through Natural Language Processing
Authors: Amer Eslam
Published: June 2019

In this article, a new approach is introduced that makes use of the valuable information that can be extracted from a patient's electronic healthcare records (EHRs). The approach employs natural language processing and biomedical text mining to handle patient's data. The developed approach extracts relevant medical entities and builds relations between symptoms and other clinical signature modifiers. The extracted features are viewed as evaluation features. The approach utilizes such evaluation features to decide whether an applicant could gain disability benefits or not. Evaluations showed that the proposed approach accurately extracts symptoms and other laboratory marks with high F-measures (93.5-95.6%). Also, results showed an excellent deduction in assessments to approve or reject an applicant case to obtain a disability benefit.

Authors: Briciu Victor Alexandru , Nechita Florin , Demeter Robert , Kavoura Androniki
Published: June 2019

The article examines a double case study framework for analyzing perceived and projected destinations by using ITC solutions. First, 22,362 photos tagged with “Brasov” were collected and analyzed using the Flickr API. Second, a descriptive-explanatory research was employed, applying an instrument for the analysis and to address the online identity of place brands where a proposed online platform generates an automatic score calculation. The spatial patterns of tourist activity revealed many similarities and differences compared to promoted attractions by the DMOs, as the results indicated that geotagged photos reflect the projected image of the destination as the data provided a hotspot distribution of popular tourist attractions. The article makes a theoretical and practical contribution: (a) visual imagery may be more fully implemented in research studies; and (b) the distribution of popular tourist attractions may be in synergy between the perceived and projected image of a destination. Implications for marketing managers are presented.
The Determinants of Adoption of Cloud-Based ERP of Nigerian's SMES Manufacturing Sector Using Toe Framework and Doi Theory
Authors: Usman Usman Musa Zakari , Ahmad Mohammad Nazir , Zakaria Nor Hidayati
Published: June 2019

Adoption factors relating to enterprise resource planning (ERP) have been studied quite extensively over the years. Most of the earlier studies on cloud ERP have focused only on technical and operational issues. A few studies have addressed the adoption of cloud ERP from the user's perspective, mostly assessing the effects of the innovation characteristics or the contextual factors. Very few studies to date have conducted a holistic evaluation of both the direct and indirect effects of the determinants on cloud ERP adoption in manufacturing SMEs. Therefore, this study aims to explore and gain an understanding of the determinants of adoption factors for cloud ERP and its relative advantage to small and medium enterprises (SME) organisations. The manufacturing SMEs in Nigeria are specifically targeted. This study also seeks to develop a research model that integrates the innovation characteristics and technology-organisation-environment (TOE) perspectives that underlie its adoption.
Impact of Digital Marketing on Consumers' Impulsive Online Buying Tendencies With Intervening Effect of Gender and Education
Authors: Sarwar-A Alam MD , Wang Daoping , Waheed Abdul
Published: June 2019

We are living in the digital age where consumers have become more elegant, and their buying intention is radically transforming from traditional to online buying behavior. This study investigates the impact of digital marketing (DM) tools on consumers' online impulsive buying tendencies (OBIT), i.e., effective (AD) and cognitive tendencies (CD) with intervening role of the gender (GDR) and education-level (EL). Four hundred surveys were randomly distributed to online shoppers in Pakistan. SEM was applied to test the proposed relationships and findings revealed a positive association between DM and consumers' OBIT. The comprehensive examination affirmed the positive interrelationships of sub-dimensions of DM on consumers' OBIT, i.e., AD and CD. It is further revealed that GDR and EL did not moderate the relationships between DM and OBIT. This study furnishes insights on how advertisers can exploit such platforms to achieve OBIT and creating effective relationships in today's digital age. This study demonstrates certain directions for academicians and practitioners.
TAR Based Hotspot Prediction in Cloud Data Centres
Authors: Raveendran Anu Valiyaparambil , Sherly Elizabeth Sherly
Published: June 2019

In this article, the authors studied hotspots in cloud data centers, which are caused due to a lack of resources to satisfy the peak immediate requests from clients. The nature of resource utilization in cloud data centers are totally dynamic in context and may lead to hotspots. Hotspots are unfavorable situations which cause SLA violations in some scenarios. Here they use trend aware regression (TAR) methods as a load prediction model and perform linear regression analysis to detect the formation of hotspots in physical servers of cloud data centers. This prediction model provides an alarm period for the cloud administrators either to provide enough resources to avoid hotspot situations or perform interference aware virtual machine migration to balance the load on servers. Here they analyzed the physical server resource utilization model in terms of CPU utilization, memory utilization and network bandwidth utilization. In the TAR model, the authors consider the degree of variation between the current points in the prediction window to forecast the future points. The TAR model provides accurate results in its predictions.
Climate Changes and Sustainable Management of Natural Resources: Challenges for Agriculture
Authors: Nikolić Svetlana Roljević , Vuković Predrag , Sarić Radojica
Published: June 2019

During the last few decades, the concentration of greenhouse gases in the atmosphere has increased. Estimates are showing that the agriculture, forestry and other land use emits less than a quarter of the total anthropogenic emissions of greenhouse gases globally and in this way endangers resources. Observing from the point of the European Union, agriculture emits 436.7 million tons of CO2 equivalents, corresponding to 9.8% of total greenhouse gas emissions. On the other hand, agricultural production is accompanied by the creation of residues, whose amount often exceeds the weight of the main product, which can be used as a source of renewable energy. About 25% of the harvest residues can be used for energy purposes, without compromising the population food safety, nor adversely affecting the fertility of the land. The aim of this article is to point out on the consequences of the harmful effects of modern agriculture on the environment, but also on the fact that agriculture can offer solutions to the challenges of climate change.
Employment and Technology in Manufacturing
Authors: McLeod Alister
Published: June 2019

Manufacturing has acted as a modern-day bellwether for the impact robotic systems have on labor. Technical systems have been known to reduce employment in certain sectors of the economy while boosting it in others. Currently, the most pervasive line of thought is that robotic systems are reducing the need for labor-intensive jobs in the United States (U.S.) and other The Organization for Economic Co-operation and Development (OECD) nations. However, the findings of this article suggest that robotic systems and labor are codependent upon one another with respect to the manufacturing sector. Further examination of the factors driving or at the root of this codependency may likely provide further insight as to how robotic systems and their usage will affect future employment.
Transmediality and the End of Disembodied Semiotics
Authors: Bateman John A
Published: June 2019

The phenomena of mixing, blending, and referencing media is a major topic in contemporary media studies. Finding a sufficient semiotic foundation to characterize such phenomena remains challenging. The current article argues that combining a notion of ‘semiotic mode' developed within the field of multimodality with a Peircean foundation contributes to a solution in which communicative practices always receive both an abstract ‘discourse'-oriented level of description and, at the same time, a biophysically embodied level of description as well. The former level supports complex communication, the latter anchors communication into the embodied experience. More broadly, it is suggested that no semiotic system relevant for human activities can be adequately characterized without paying equal attention to these dual facets of semiosis.
Translating the University
Authors: Marais Kobus
Published: June 2019

This article explores the use of indexicality for understanding the emergence of social-cultural habits. Based on the work of Parmentier, it works on a methodology in which social-cultural artefacts or patterns are regarded as traces of the semiotic processes through which they were formed. It proceeds from a definition of translation as the imposition of constraints on semiotic material, i.e. semiotic work, and explores the effects of this work as indexes of the work. The article then considers data from the University of the Free State (UFS) in a demonstration of the possibilities of this kind of analysis, suggesting that the UFS is mostly constructing its identity around foreignizing influences and excluding indigenous links.
Hyperliterature and Intermediality in the Expansion of Literary Production
Authors: Collin Luci
Published: June 2019

The so-called ‘Information Revolution,' which begun in the 1990s and generated a global system of expansion of the virtual space, imposed reconfigurations on artistic expressions. In regard to literature, one sees not only the transposition of consecrated genres and textual forms into digital media, but also the creation of a specifically digital literature, one that is often marked by intermediality. The present article aims at approaching concepts such as ‘hypertext' and ‘hyper-writing', and the phenomena linked to digital textualities as ‘hyperfiction', ‘hyperpoetry', ‘holopoetry' and ‘hyperdrama', among others; besides, it also raises the question: to what extent does hyperliterature interfere with the status of “conventional literature” written and read in paper?
Towards a Text-World Approach to Translation and Its Pedagogical Implications
Authors: Tian Lu , Wang Hui
Published: June 2019

Although it is widely acknowledged that translation is a cognitive process, there is scarcely any study establishing connections between the text and mental representations and giving a systematic and comprehensive explanation for this pivotal yet magical mechanism. Illuminated by Text World Theory, this study proposes a text-world approach to translation studies and addresses its implications for translator training. Translation is regarded as a cognitive communicative process of reproducing texts as worlds. The (in)coherence among text worlds as they are represented in translation provides a legitimate criterion for the evaluation of translation competence. To view translation as a cognitive-linguistic process of text-world construction and presentation may promise a more proactive approach to translator training by encouraging translator trainees to pay special attention to the expansion of their knowledge structures.
Quantifying the Lemma Massa as a Proper-Name in the John and Massa Tales
Authors: Knight Floyd
Published: June 2019

English nouns have been described as having the ability to “switch easily between common-noun and proper-name uses.” Such changes or transformations are sometimes misanalysed by researchers and are often hard for ELL and L2 ESL researchers to detect. In this article, the author will analyze and tag the use of the Lemma MASTER (Massa/Maussa/Marsta/Marster/Master) as both a proper-name and as a common noun in the John and Massa tales from three corpora as well as provide a procedure for doing mixed method research to adjudicate differences in analysis offered by various scholars. The author will also discuss the need to add a fourth condition to Kripke's definition for proper names and why undertaking pragmatic and contextual analysis is warranted.

Published: June 2019

The ceramic fibers can be obtained from different techniques. Due to the technological development, searches are performed to improve the existing fibers. Thus, recent studies have enabled the development of an unprecedented synthesis route for the production of nanofibers, the Solution Blow Spinning (SBS). In this context, the present work proposes to develop silica nanofibers doped with silver by the SBS method, evaluating parameters such as: silver content and acidification of solutions. The fibers were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The results of XRD showed that the samples with 4% silver that were not acidified showed the most defined and intense characteristic peaks. The SEM showed the formation of fibers with diameters in the nanometer range independent of acidification or not of the solutions, with reduction of the agglomerates in the samples with 2% silver.

Authors: Cunha Rochelia Silva Souza , Mota Joseane Damasceno , do Nascimento Silva Fabiana Medeiros , Rodrigues Meiry Gláucia Freire
Published: June 2019

This objective of this study was to produce organoclay, analyze it, and evaluate its use in the process of removing oil emulsion from an oil–water system. The organoclay was prepared by the direct method and was characterized using X-ray diffraction, Cation Exchange Capacity (CEC), and Infrared Spectroscopy (IV). A finite bath system was used to evaluate the effects on the removal capacity, using a stirring speed (A) of between 100 and 300 rpm and an initial concentration of oil-water solution (C0) evaluated in the range of 100 to 500 mg/L. The XRD and infrared results indicated that CTAC was intercalated between the layers of Bofe clay. The percentage of oil removal from oil-in-water emulsions was between 55.99 and 96.62%. These results indicate that OC can potentially remove up to 97% oil from oil-in-water emulsions. Consequently, the OC could be considered an excellent medium for treating oily water.

Published: June 2019

The present study describes the preparation of catalyst MoO3 supported on smectite clay by the solution impregnation method and its evaluation as a heterogeneous catalyst in the production of biodiesel from soybean oil. The individual effects of catalyst (hard green clay and MoO3/hard green clay) on kinematic viscosity of produced biodiesel and conversion were investigated. The samples were characterized by X-ray diffraction, X-ray fluorescence spectroscopy and N2 adsorption-desorption. Conditions of soybean oil transesterification were: 5% catalyst by weight, 1:12 oil to methanol molar ratio, at 200 oC for 60 minutes.

The Pseudoboehmite is an aluminum compound used as an alumina precursor and it is produced by sol-gel process. The sol-gel process is a methodology to produce porous, vitreous or crystalline ceramics started by molecular precursors. Pseudoboehmite with high purity, high specific surface area and porous homogeneity was obtained by sol-gel process. The material was used to produce gamma-alumina with surface area ranging from 211.2-288.1m2/g. It was studied the effect of aging time, temperature of aging and poly (vinyl alcohol) addition in the synthesis.

We study the sound absorption coefficient of rubberized mortars in response to the incorporation of 7.5%, 15% and 30% of waste-tire rubbers in place of sand at a water-to-cement mass (w/c) ratio of 0.48. We consider two different morphologies of rubber particles, namely spheroid (S) and fiber-like (F) particles. Experimental characterization was performed after 7 days of curing. The mixtures were performed by density, water absorption, void index and sound absorption. We choose the transfer function method with one microphone successively in two locations in order to obtain the sound absorption coefficient using an impedance tube. Sound absorption coefficient results indicate a slightly enhancement for 7.5% S, 15% S, 30% S and 7.5% F mixtures from 1600 Hz to 2000 Hz. The best acoustic performance is observed for 30% S and 7.5% F mixtures from 850 Hz to 2000 Hz.

During the last few decades many researchers have been interested in acoustic wave propagation in artificial periodic composites known as sonic crystals. Sonic crystals have received renewed attention because they exhibit acoustic band gaps where there are only evanescent waves. Sonic crystals consist of a periodic array of scatterers embedded in a host medium. The host medium and/or scatterers are fluids. We investigate the band structure of acoustic waves propagating in a sustainable sonic crystal composed by miriti fibers and air, regarding square and triangular lattices. Miriti fibers are extracted from buriti palm petiole (Mauritia flexuosa Mart.), which is a typical specie that grows in Amazonian region. We also study the influence of miriti fiber cross section, i.e. circular, hollow circular, square and rotated square with a 45° angle of rotation with respect to x, y axes. Plane wave expansion method is used to solve the wave equation. Acoustic band gaps are observed for all miriti fiber cross sections and lattices. The best performances of the sustainable sonic crystal are for triangular lattice, regarding circular and rotated square miriti fiber cross sections, and for square lattice with circular miriti fiber cross section. We suggest that the sustainable sonic crystal should be feasible for noise management.

The aim of the present study is to assess the physical-mechanical properties of hydroxyapatite-titanium oxide composites used in porous scaffolds produced by the polymeric wax addition method. Mixtures composed of 50%-50%wt. (sample A), 60%-40%wt. (sample B), and 70%-30%wt. (sample C) of hydroxyapatite-titanium oxide were prepared. Subsequently, 70%vol. of each sample was combined with 30%vol. polyethylene wax. Forty-five (45) specimens per composition (12 mm diameter and 10 mm height) were prepared through uniaxial pressing. The specimens were subjected to calcination at 500°C (1°C/min) and left to rest for 1 h for polymeric wax elimination. Next, they were sintered at 1250°C, 1300°C, and 1350°C for 2 h. Physical-mechanical assays were conducted to assess apparent porosity, water absorption, specific gravity, firing linear retraction, and ultimate compression strength. As temperature increased, firing linear retraction, specific gravity, and ultimate compression strength increased in all samples, whereas water absorption and apparent porosity decreased. Sample A presented the highest densification and ultimate compression strength rates at 1350°C. Overall, the physical-mechanical characteristics of these composites made them suitable to be used as biocomposites.

The aim of this study was to evaluate the influence of shear and micro-shear tests on adhesive resistance and on defects in restorations in human dentin. The teeth were sectioned and embedded. The dentin surface was treated with universal system adhesive and the samples were divided into two groups. In the first, composite resin pins were fixed with 1 mm diameter and in the second, pins with 2 mm. After mechanical tests the samples were taken to the SEM for analysis of fractures. Tensile strength on G1 was 16 MPa and on G2 20 MPa. The fractures occurred after shear were mostly mixed and cohesive in dentin. On micro-shear adhesive and mixed, no cohesive. It can deduce that, the diameter of the pin influenced the adhesive resistance and the type of failure. Therefore, for evaluation of adhesive strength in dentin the test indicated is micro-shear.

One new genus of Inocelliidae (Raphidioptera) with one new species and one undetermined specimen is described from the Eocene of North America: Paraksenocellia borealis new genus, new species from the early Eocene (Ypresian) Okanagan Highlands shale at Driftwood Canyon, British Columbia, Canada (a forewing), and Paraksenocellia species from the middle Eocene (Lutetian) of the Coal Creek Member of the Kishenehn Formation, northwestern Montana, United States of America (a hind wing). These are the oldest records of the family. The new genus possesses many character states that are rare in Inocelliidae, e.g., a very long pterostigma extending to ScP in both the forewings and hind wings; the forewing subcostal space has three crossveins; the forewing and hind wing AA1 are deeply forked; the crossvein between CuA and CuP is located far distad the crossvein 1r-m. Paraksenocellia is confidently a member of the Inocelliidae, as it possesses a proximal shift of the basal crossvein 1r-m (connecting R and M) in the forewing and the loss of the basal crossvein 1r-m in the hind wing, both apomorphies of the family. It shares some character states with the Mesozoic Mesoraphidiidae, which we consider to be mostly stem-group plesiomorphies.
