Authors: Alawatugoda Janaka , Vivekaanathan Seralathan , Peiris Nishen , Wickramasinghe Chamitha , Chuah Chai Wen
Published: November 2018

Security models have been developed over time to analyze the security of two-party authenticated key exchange (AKE) protocols. LaMacchia et al. (ProSec 2007) presented a strong security model for AKE protocols, namely the extended Canetti-Krawczyk (eCK) model, addressing wide range of real-world attack scenarios. They constructed a protocol called NAXOS, that is proven-secure in the eCK model. In order to satisfy the eCK security, the NAXOS protocol uses a hash function to combine the long-term secret key and the ephemeral secret key, which is often called as “NAXOS-trick”. However, for the NAXOS-trick-based protocols, the way of leakage modelled in the eCK model leads to an unnatural assumption of leak-free computation of the hash function. Precisely, the eCK model allows the attacker to reveal the ephemeral key while the output of the NAXOS-trick computation remains safe (leak-free). In a recent work of Alawatugoda et al. (IMA Cryptography and Coding 2015), a NAXOS-trick-free eCK-secure AKE protocol is presented, namely protocol P1. In this work, we implement the protocol P1 to be used with the widely-used OpenSSL cryptographic library. OpenSSL implementations are widely used with the real-world security protocol suites, such as Security Socket Layer (SSL) and Transport Layer Security (TLS). As per best of our knowledge, this is the first implementation of a eCK-secure key exchange protocol for the OpenSSL library. Thus, we open up the direction to use the recent advancements of cryptography for real-world Internet communication.

Published: November 2018

Chewing tobacco is a tobacco that people consume by chewing. The main content of substances in tobacco is nicotine that is harmful to health because it poisoned pregnancy. The results of Indonesia's basic health research in 2013 revealed the prevalence of smoking and chewing tobacco consumption was 36.3%. This survey showed that iron deficiency anaemia in pregnant mother also high was 29%. District Bangun Purba Simalungun Regency is an area where chewing tobacco consumption done in many people, not only elderly but also young people including pregnant mother. The aim of this research is to analyze the relationship of chewing tobacco intake and food consumption with high fondues uteri in pregnant mother with cross sectional study design. The sample was 94 pregnant mothers second trimester and third trimester. The results showed that 31.9% pregnant mother have below adequacy protein consumption and 35.1% pregnant mothers have below adequacy iron consumption. The research also showed that 36.2% mothers have abnormal the high fondues uteri and only 63.8% mothers in normal category of high fondues uteri. Chewing tobacco intake is still performed on some pregnant mother whose frequency varies from frequency to occasional frequency to day. Statistical analysis showed positive correlation between chewing tobacco intake during pregnancy and high fondues uteri. The other hands the relationship between chewing tobacco intake before pregnancy and high fondues uteri showed no significant correlation. Although there is no correlation between chewing tobacco intake before pregnancy with high fondues uteri does not mean that chewing tobacco may be consumed by pregnant mother. Socialization of chewing tobacco habits in pregnant mother should be done by health workers at Bangun Purba Health Centre and Simalungun District Health Office.

Published: November 2018

Now a day, Authentication process in biometric system become most critical task with the expansive of individual information in the world. Where in many current applications, devices and commercial treatments required fingerprint identification process in order to verify the requested services. Most technologies also motivate to this direction. With the increasing of fingerprints uses, there is a need to provide a technique that able to handle the issues that exist in fingerprint acquisition and verification processes. Typically, fingerprint authenticated based on pick small amount of information from some points called Minutiae points. This approach suffers from many issues and provide poor results when the samples of fingerprints are degraded (scale, illumination, direction) changes. However, BRISK algorithm used to handle the previous issues and to extract the significant information from corner points in fingerprint. BRISK is invariant to scale, illumination, and direction changes and its able to pick large number of information when compared with minutiae points. In this paper, BRISK algorithm used based on image based approach, where current recognition matrices are developed and proposed new metrics without need for human interaction. UPEK dataset used to test the performance of proposed system, where the results show high accuracy rate in this dataset. Proposed system evaluated using FAR, FRR, EER and Accuracy and based on selected metrics the proposed system and methodology achieve high accuracy rate than others, and gives a novel modification in authentication task in biometric systems

Authors: Rozalina Rianti , Mansor Zulkefli
Published: November 2018

Software cost estimation (SCE) in software management can be a complicated task, as it could yield inaccurate results. Based on new empirical evidence, Public sectors more often face estimation failure, which causes projects to over shoot budgets, get delayed, face termination or the project scope or requirement to remain incomplete. Hence, the main aim of this paper is to identify the critical factors that significantly impact SCE in the context of software development in the Indonesian regional government. This research employs a quantitative approach, in which a questionnaire is used as the data collection instrument. The data is analysed using a RASCH model. This study is conducted in the regional government of West Sumatera Province, Indonesia. The result of the study reveals that there are six critical factors that significantly impact SCE results in a government project. These critical factors are programmer capability, top management support, the understanding of top management regarding the objectives of the project, risk management, knowledge, competency of the project manager, and top management involvement in the project.
Comparative Analysis of Different Data Representations for the Task of Chemical Compound Extraction
Authors: Alshaikhdeeb Basel , Ahmad Kamsuriah
Published: November 2018

Chemical Compound Extraction refers to the task of recognizing chemical instances such as oxygen nitrogen and others. The majority of studies that addressed the task of chemical compound extraction used machine-learning techniques. The key challenge behind using machine-learning techniques lies in employing a robust set of features. In fact, the literature shows that there are numerous types of features used in the task of chemical compound extraction. Such dimensionality of features can be determined via data representation. Some researchers have used N-gram representation for biomedical-named entity recognition, where the most significant terms are represented as features. Meanwhile, others have used detailed-attribute representation in which the features are generalized. As a result, identifying the best combination of features to yield high-accuracy classification becomes challenging. This paper aims to apply the Wrapper Subset Selection approach using two data representations—N-gram and detailed-attributes. Since each data representation would suit a specific classification algorithm, two classifiers were utilized—Naí¯ve Bayes (for detailed-attributes) and Support Vector Machine (for N-gram). The results show that the application of feature selection using detailed-attributes outperformed that of N-gram representation by achieving a 0.722 f-measure. Despite the higher classification accuracy, the selected features using detailed-attribute representation have more meaning and can be applied for further datasets.

Published: November 2018

This research is carried out to evaluate important community resilience aspects of coastal districts in Sri Lanka and to provide suitable recommendations to strengthen them. After carrying out an indepth literature survey and interviewing key personnel who are involved in the field of Disaster Management and Disaster Risk Reduction, existing status of the coastal hazards, multi-hazard assessments, early warning mechanisms, national policies, guidelines and efforts and regional cooperation were identified. During the literature survey, it was observed that Sri Lanka has developed a Hazard profile for the country and has an Early Warning Dissemination System which seems to function quite well by the book. What is more, the country is in the process of orienting the existing national policies and guidelines with the post 2015 global standards such as the Sendai framework and Sustainable Development Goals. Sri Lanka being a member of Indian Ocean Tsunami Warning and Mitigation System (IOTWMS) and Regional Integrated Multi-Hazard Early Warning System for Africa and Asia (RIMES) depicts that the country has a good regional cooperation in terms of Early Warning. Even though Sri Lanka lacks efficient and sustainable resilience mechanisms focused on the coastal communities, national efforts are underway to build up the coastal resilience. Training and public awareness campaigns, efficient funds, properly maintained hierarchy and concern to the coastal ecosystems are some of the enablers identified in this study which are associated in building coastal resilience. Developing and updating a multi-hazard map, improving the interagency cooperation and driving towards a people-centred Multi-Hazard Early Warning System (MHEWS) are some of the recommendations given after the analysis

Published: November 2018

Oil palm frond has been used for many applications especially as a source of industrial fibers. Drying of oil palm frond particles is essential before the material could be used for subsequent applications. This research aimed to study the drying kinetics of oil palm frond particles in a spouted bed dryer. Spouted bed dryer has been used by various industries because of its ability to dry large size and irregular shape particles. In this research, experiments were conducted to study the effect of various operating variables on the drying kinetics of oil palm frond particles in a spouted bed dryer. The manipulated variables were hot air temperature, superficial air velocity and bed height. Batch drying experiments of oil palm frond particles were performed by varying the hot air superficial velocity (1.3 m/s, 1.5 m/s and 1.6 m/s), temperature of hot air (50â°C, 60â°C and 70â°C) and bed height (10 cm and 15 cm). For comparison purposes, samples of oil palm fronds were also dried under the sun. The fiber color changes subjected to two different drying methods were also observed. Drying kinetic results from the spouted bed drying experiments indicated that the drying duration decreased with an increased in air temperature and air velocity and a decreased in bed height. The color of the fiber from spouted bed dryer was less deteriorated compared to that dried by direct sun drying. Drying of oil palm fronds in a spouted bed dryer produced fibers that were lighter in color than the product dried by sun drying.

Internet of things grown very rapidly, one of them is application smartcity for monitoring the environment. The environmental monitoring use the wireless sensor networks (WSN) technology to collect all of the data. All the data collected by the WSN will be sotred in the Data Center, where all of the data in the Data Center can be accessed by the user everytime and everywhere. The data center without security mechanism is very dangerous because all of data can be tracked and even modified by the users. There are need security mechanism for securing the data and monitoring access from each user. Chipertext Policy Attribute Based-Encryption (CP-ABE) with Authentication and Revocation can become a solution for this problem, where all of data in the data center can be protected with encryption and decryption mechanism. Its jut not protect the data, the security will give a guarantee for originality in the data and can give a control access for user who did the illegal access. The user who did the illegal access will be revoked by the system. Our security mechanism using the CP-ABE and timestamp digital signature using Rivest, Shamir Adleman (RSA) 2048 does not affect to performance of the system.

The role of career surveys: Identifying issues and evaluating practice
Authors: Jackson Charles
Published: November 2018

Drawing on the results of two surveys of early career doctors conducted 12 years apart, this paper discusses how such surveys can identify career concerns and provide evidence of the effectiveness of career interventions. The first survey identified the need for more and better career advice in medical training. Since then, there have been considerable changes to the structure of medical training and a number of initiatives to improve the career support given to these doctors. It is argued that career surveys are an important way of monitoring and evaluating change over time but also have the potential to make a valuable contribution to informing and evaluatingcareer interventions in a range of settings.
Espacio urbano de proximidad. Una visión de género a través del cine
Authors: De Santisteban López Amparo
Published: November 2018

El urbanismo contemporáneo y la calidad de vida en nuestras ciudades se cuestionan desde diferentes sectores. Los nuevos y rápidos crecimientos, sobretodo de las últimas décadas, representan el individualismo, el consumo y la segregación. Esta situación se manifiesta especialmente en los gruposmás vulnerables como son la población afectada por el uso y dominio del espacio urbano según categoría de género. Las nuevas líneas de pensamiento sobre la ciudad, como ente complejo y en evolución que necesita flexibilidad para adaptarse a las personas que la habitan, implican observarla y trabajar en ella desde la escala de la proximidad.Por otro lado, el cine desde sus orígenes es una importante fuente documental de entornos y ambientes urbanos existentes o teóricos. Se plantea pues, como hipótesis la utilidad de este medio como herramienta para el análisis, denuncia y reflexión del fenómeno urbano desde la perspectiva de género. La metodología adoptada se aplica dos películas de diferente época, director, localización y vocación, confirmándose la importancia del material cinematográfico como instrumento para el análisis urbanístico.

Procesos de re escalamiento territorial en los asentamientos rurales del sur de Marruecos debidos a las nuevas tipologías de organización espacial humana. El caso de los oasis del Valle del Drâa.
Authors: Colmenares Fernández Marta
Published: November 2018

ResumenLas condiciones planetarias en las que actualmente vivimos otorgan gran importancia al hecho de que las geografías de la urbanización trasciendan la propia ciudad, metrópolis o región para instalarse en todos los territorios del planeta. Asimismo, las políticas nacionales de la mayoría de los países, basadas en la economía de mercado, se han centrado en la implantación de recursos en torno a las grandes áreas urbanas, por lo que los asentamientos humanos (urbanos o rurales) han sufrido un paulatino proceso de re-escalamiento territorial, donde su organización espacial ya no se inscribe en un territorio cercano, sino que sobrepasa los límites físicos de sus espacios construídos.Sostiene Brener que, históricamente, lo urbano se ha concebido como un espacio de asentamiento específico diferente de los espacios presuntamente no urbanos que lo rodean: desde los suburbios, las áreas rurales, el campo o las superficies naturales. Es decir, lo urbano se define en contraposición a lo otro. En la actualidad, la reorganización espacial planetaria ya no asume una división entre lo urbano y lo rural.Este es el caso del Valle del Drâa, al sur de marruecos, donde las políticas nacionales del gobierno marroquí, que comenzaron en los años 70 con la construcción de grandes infraestructuras de signo territorial, continúan a día de hoy mediante la transformación económica de la región donde éste valle se sitúa, basada en una economía de signo capitalista y mercantil, y cuyas actuaciones ha provocado cambios en las estructuras socioculturales, económicas y urbanas.Palabras claveRe-escalamiento; áreas ruralesAbstractNowadays, the global conditions in which we live today give high importance to the fact that the urbanization geography exceeds the limits of the cities, metropolis or regions, to pervade every place of the planet. Furthermore, the market economy-based national policies of most of the countries, have focused in accumulate resources all around the metropolitan areas. Thus conceived, urban and rural areas have undergone a re escalation process.This is the case of the Draa valley, where national policies of Moroccan government started in 70´s with the construction of major territorial infrastructures and continue until today. Now, the economic transformations of the region have brought big changes in social, economic and urban conditions.To understand this process that involve both local changes and global dynamics, it was sought out to the debate of scaling theories and territorial escalation involved in globalization and neoliberalism.KeywordsRe-scaling, rural areas
El área urbana funcional de Madrid (1991-2011) Metodología y resultados de una propuesta de delimitación y caracterización multicriterio
Authors: Gómez Giménez José Manuel
Published: November 2018

ResumenEsta investigación centra su atención en el análisis de los procesos constitutivos de lo urbano, más allá de las delimitaciones territoriales administrativas. Es fundamental arrojar luz sobre dichos procesos para estudiar las dinámicas y disyuntivas que enfrentan nuestros desiguales territorios urbanos. Con esta visión se propone una metodología para delimitar el área urbana funcional de Madrid y establecer sobre ella una diferenciación zonal que conjugue la existencia de un gradiente de intensidad de sus procesos constitutivos con la fracturación social de su espacio. Por último, un análisis multicriterio, a través de la generación de índices sintéticos, comparativos entre las diferentes zonas demarcadas, aportará una base descriptiva sobre la que evaluar tanto el acierto metodológico de la delimitación y caracterización del área funcional como su modelo evolutivo de desarrollo durante las últimas dos décadas. Los datos obtenidos arrojan luz sobre la validez de la tradicional dicotomía madrileña noroeste-sureste, así como, sobre la insostenibilidad del modelo en generación.Palabras clave  Territorio urbano; urbanización extensiva; movilidad; segregación espacial; ocupación insostenible; vulnerabilidadAbstractThis research focuses on the analysis of constitutive urban processes rather than preconceived demarcations of urban sites. This is of paramount importance to cast further light on the dynamics and dilemmas which our unequal urban territories are facing. With this view, the research proposes a methodology to identify geographically Madrid’s functional urban area and stablish it distinct zones. This task of zoning combines the existence of an intensity gradient in its constitutive urban processes with the social-spatial segregation pattern of Madrid. After that, a multi-criteria analysis through comparative synthetic indexes will lay the foundation for evaluating the methodology being followed heretofore and the characterization of the functional urban area. Finally, all outcomes will provide us with enough information to express a reasoned judgement on the evolutionary development of the area over the past two decades. The conclusion is the validity of the traditional segregation pattern, as well as the unsustainability of the current model set out in the area.KeywordsUrban territories; extended urbanization; mobility; social-spatial segregation; unsustainable land use; vulnerability

Alimentación de proximidad. Territorializaciones posibles de una alianza entre los mercados municipales y el territorio agrario periurbano de Madrid
Authors: Álvarez del Valle Lucas
Published: November 2018

ResumenEl sistema agroalimentario actual subordina la agricultura y el pequeño comercio, en los dos extremos de la cadena alimentaria, a las industrias de insumos agrarios, transformación alimentaria y gran distribución comercial. La agricultura periurbana sufre además la presión de un crecimiento urbano que provoca el deterioro y desaparición del territorio agrario próximo a las ciudades, antaño la base del abastecimiento alimentario de las mismas. Además, los mercados, que por mucho tiempo funcionaron como punto de entrada de los alimentos a la ciudad, van paulatinamente perdiendo comerciantes y consumidores. El objetivo de esta investigación es explorar las posibilidades de una alianza entre los mercados municipales de Madrid y su territorio agrario periurbano que permita su supervivencia favoreciendo la producción y consumo de proximidad, dimensionando la capacidad productiva del territorio y de la demanda que puede ser cubierta por los mercados y evaluando escenarios para una territorialización posible de dicha alianza.AbstractThe current agri-food system subordinates agriculture and small retail (in the two ends of the food chain) to the agricultural inputs and food processing industries and to the large retail sector. The periurban agriculture also suffers the urban growth pressure that causes the deterioration and disappearance of the agrarian territory close to the cities, formerly the base of the urban food supply. In addition, markets, which had served as food entry point into the city for a long time, are now gradually losing sellers and consumers. The objective of this research is to explore the possibilities of an alliance between Madrid’s municipal markets and its periurban agrarian territory to favor proximity production and consumption, sizing both the farming territory’s capacity and the food demand that might be covered by the markets to evaluate scenarios for a possible territorialization of this alliance.

Background: The febrile patient from tropical areas, in which emerging arboviruses are endemic, represent a diagnostic challenge and potential co-infections with other pathogens (i.e bacteria or parasites) are usually overlooked. Objectives: We present a case of an elderly woman diagnosed with dengue, chikungunya and Leptospira interrogans co-infection. Study Design: Case report. Results: An 87-year old woman from Colombia complained of upper abdominal pain, arthralgia, myalgia, hyporexia, malaise and intermittent fever accompanied with progressive jaundice. She had a medical history of chronic heart failure (Stage C, NYHA III), without documented cardiac murmurs, right bundle branch block, non-valvular atrial fibrillation, hypertension, and chronic venous disease. Her cardiac and pulmonary status quickly deteriorated after 24 hours of her admission without electrocardiographic changes and she required ventilatory and vasopressor support. In the next hours the patient evolved to pulseless electrical activity and then she died. Dengue IgM, NS1 ELISA, MAT for Leptospira interrogans and RT-PCR for chikungunya, were positive. Discussion: This case illustrates a multiple co-infection in a febrile patient from a tropical area of Latin America that evolved to death.

Authors: Athiroh Nour , Wahyuningsih Doti
Published: November 2018

The aim of this research was to investigate the potential effect of methanolic extract of Scurrula atropurpurea (MESA) in reducing oxidative stress through observation of superoxide dismutase (SOD) activity and malondialdehyde (MDA) concentration in mice. In this research, 25 male mice were divided into four groups with five replications. Group I (K1, without MESA) was considered as a control group, while Group II (K2), III (K3), and IV (K4) were given 1000, 2000, and 4000 mg MESA/kg BW, respectively. After 14 days, SOD activity and MDA concentration were measured spectrophotometrically. The SOD activity did not significantly increased (P0.05) in group K1, K2, K3, and K4 with values were 19.469±2.072, 17.4±1.373, 20.53±3.411, and 23.87±2.528 U/ml, respectively. In contrast, MDA concentration was decreased (P0.05) with values of 492.750±19.418, 492.750±19.418, 457.125±30.095, 454.625±19.080, and 475.875±37.659 ng/mL in groups K1, K2, K3, and K4, respectively. It can be concluded that the administration of  MESA tend to increase SOD activity and decrease MDA concentration in this study, thus might be able to reduce  oxidative stress in mice.

The aim of this study was to determine the effect of neem leaf extract (Azadirachta indica) on parasitemia of rats infected with Trypanosoma evansi (T. evansi) Aceh local isolate. A total of 24 male rats aged three months were used in this study and randomly divided into six treatment groups equally. The negative control group (K0) without T. evansi infection and neem leaf extract, the positive control group (K1) was infected with T. evansi but no neem leaf extract given, group K2, K3, K4, and K5 were infected with 5x104 T. evansi and were given neem leaf extract after patent infection with dose of 50, 100, 400, and 800 mg/kg BW respectively. The extract was given orally for three consecutive days. On the fourth day, rat blood was drawn for parasitemia examination. The results showed that no T. evansi detected in rats in negative control group (K0), while parasitemia in group K1; K2; K3; K4; and K5 was 12,295 x106/mL; 10,495 x106/mL; 9,360 x106/mL; 5,080x106/mL; and 2,398x106/mL of blood, respectively. Percentage of inhibition of parasitemia in K2, K3, K4, and K5 reached 14.64, 23.78, 58.68, and 80.50%, respectively. Based on the result of the study, neem leaf extract of 800 mg/kg BW gave the highest reduction of parasitemia in rats infected with T. evansi.

The objective of this study was to examine the effects of repeated freeze-thaw cycles and short-term storage of fecal extracts at ambient temperature on the stability of fecal glucocorticoid (fGCM) and estrogen metabolite (fEM) levels from crested macaques.In total 100 aliquots of fecal extracts from fecal samples collected from female crested macaques (Macaca nigra) living at the Tangkoko-Batuangus Nature Reserve, North Sulawesi were used. We performed two different experiments: (1) An experiment to investigate if levels of fGCM and fEM measured from fecal extracts that were exposed to two, four, six and eight repeated freeze-thaw cycles (test groups) differ to control samples (i.e. fecal extracts always stored frozen); (2) An experiment to evaluate whether storing fecal extracts at ambient temperature for two, four, six, and eight days (test groups)affects the levels of fGCM and fEM compared to the control group (i.e. fecal extracts frozen immediately).Results showed that hormone levels were significantly increased (P0.05) after four freeze-thaw cycles for fGCM and after eight freeze-thaw cycles for fEM. By contrast, there was no significant difference (P0.05) in levels of fGCM and fEM between the test groups and the control group in fecal extracts stored at ambient temperature. In conclusion, our data show that more than two and six repeated freeze-thaw cycles should be avoided when measuring fGCM and fEM in crested macaque fecal extracts, respectively. We also demonstrate that storing fecal extracts at ambient temperature is possible for at least 8 days without taking a risk of affecting the stability of fGCM and fEM levels.

This study was conducted to investigate the histological characteristic, type, and distribution of connective tissue in Sunda porcupine skin. The investigation was carried out in three adult of sunda porcupines at microscopic level using hematoxylin eosin, Masson thrichrome, Verhoeffs van Gieson, alcian blue pH 2.5 and periodic acid Schiff staining methods. Skin consists of epidermis, dermis hypodermis, and subcutaneous muscle. Quill follicles were the main and dominant structure as well as the specific characteristic on Sunda porcupine skin. The connective tissue was distributed well in basal membrane, dermis, quill follicle, and hypodermis with various intensity and density. The collagen was the main fiber found in the skin while the elastin fiber was not observed. The acid carbohydrate was found distributed well in the skin while the neutral carbohydrate was not detected in this study. In addition the fibers of connective tissue associated with the adipose tissue which found plentifully in quill follicles and hypodermis. The present results showed that the wide distribution of connective tissue might have an important role on the wound healing physiology of Sunda porcupine skin.

This study aimed to determine whether the variant or biotype of Trypanosoma evansi can be seen from their polypeptide profiles using 12%sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) stained with Brilliant Blue Commasie. The results generally showed thatthe molecular weight (MW) of polypeptides from nine isolates from East Java, Central Java, Banten, South Kalimantan, Central Kalimantan, andLampung provinces were in the range of 85.46 to 15.76 kD and each isolate has different polypeptide profile. Isolates A13 and A14 were isolatedfrom the same place but have different polypeptide profiles. Likewise, isolates S13 and S18 also have different polypeptide profiles despite beingisolated from the same place at the same time. On the other hand, isolate 372, 87, and 06 have different protein profiles but was classified in thesame biotype namely biotype I. Generally, the difference in protein profile actually more related to the biological diversity of the metabolism ofeach Trypanosoma evansi isolate from Indonesia.

This study aimed to determine the role of guava fruit filtrate (GFF) on maintaining the pre-freezing and post-thawed quality of Bali bullspermatozoa in tris-egg yolk (TEY) extender. The bovine semen was collected using artificial vagina twice a week (n= 10). Ejaculate sampleswere divided into four tubes and each tube was respectively added the following diluents: TEY, TEY + 5% GFF, TEY + 10% GFF, and TEY +15% GFF. The diluted semen was filled into the straws (0.25 mL) and cooled in refrigerator at 4° C for 2.5 hours. The samples were kept onvapor phase of liquid nitrogen (N2) (-120° C) for 10 minutes prior to be stored in liquid phase (-196° C). The quality of pre-freezing and postthawedspermatozoa in straw sample (i.e. motility, viability, and abnormality) was evaluated under light microscopy at 400x magnification. Datawere analysed statistically. The percentage of motility and viability both on pre-freezing and post-thawed process were significantly higher insemen diluted with TEY + 10% GFF compared to control (TEY), TEY + 5% GFF, and TEY + 15% GFF. Addition of 10% GFF into tris-egg yolkextender play role for maintaining the quality of pre-freezing and post-thawed Bali bull spermatozoa.

Authors: Takakura Sandra Mina
Published: November 2018

Este artigo apresenta os resultados de estudo sobre neologismos em uma pequena seleção de obras da exposição intitulada Luzescrita (2013-), composta por poemas de Arnaldo Antunes, montagem e registros permanentes em fotografia, de Fernando Lazslo. Os trabalhos selecionados resultam da convergência dos processos de criação literária e artística, em estreita relação com os processos linguísticos. O estudo adota a expansão conceitual de heterodiscurso de Bakhtin (2015), a fim de incluir os distintos estilos, linguagens e sistemas axiológicos em mídias diferentes no embate semântico das criações neológicas. Os trabalhos resultam das variadas interações entre humanos e tecnologia (LATOUR, 2005), na era do Antropoceno.
Aspectos morfológicos dos verbos na língua Mehináku (Arawak)
Authors: De Felipe Paulo Henrique Pereira Silva
Published: November 2018

O objetivo principal deste trabalho é apresentar uma análise inicial da morfologia dos verbos na língua Mehináku (Arawak). Os verbos, nesta língua, dividem-se transitivamente em dois tipos: (i) verbos transitivos, que requerem dois argumentos obrigatórios (um agente/sujeito como argumento externo e um objeto como argumento interno) e (ii) verbos intransitivos, que admitem apenas um argumento (um agente/sujeito como argumento externo). Do ponto de vista morfológico, os verbos são acompanhados por prefixos pronominais, que geralmente representam o argumento externo da construção, além de sufixos marcadores de tempo e aspecto. Os argumentos internos não são marcados no verbo, mas expressos sintaticamente.
