Load Balanced Clustering Technique in MANET using Genetic Algorithms
Authors: Kaliappan M. , Mariappan E. , Prakash M. Viju , Paramasivan B.
Published: May 2016

Mobile adhoc network (MANET) has characteristics of topology dynamics due to factors such as energy conservation and node movement that leads to dynamic load-balanced clustering problem (DLBCP). Load-balancing and reliable data transfer between all the nodes are essential to prolong the lifetime of the network. MANET can also be partitioned into clusters for maintaining the network structure. Generally, Clustering is used to reduce the size of topology and to accumulate the topology information. It is necessary to have an effective clustering algorithm for adapting the topology change. In this, we used energy metric in genetic algorithm (GA) to solve the DLBCP. It is important to select the energy- efficient cluster head for maintaining the cluster structure and balance the load effectively. In this work, we used genetic algorithms such as elitism based immigrants genetic algorithm (EIGA) and memory enhanced genetic algorithm (MEGA) to solve DLBCP. These schemes select an optimal cluster head by considering the distance and energy parameters. We used EIGA to maintain the diversity level of the population and MEGA to store the old environments into the memory. It promises the load -balancing in cluster structure to increase the lifetime of the network. Experimental results show that the proposed schemes increases the network lifetime and reduces the total energy consumption. The simulation results show that MEGA and EIGA give a better performance in terms of load-balancing.
PICO : An Ultra Lightweight and Low Power Encryption Design for Ubiquitous Computing
Authors: Bansod Gaurav , Pisharoty Narayan , Patil Abhijit
Published: May 2016

An ultra-lightweight, a very compact block cipher ‘PICO’ is proposed. PICO is a substitution and permutation based network, which operates on a 64 bit plain text and supports a key length of 128 bits. It has a compact structure and requires 1877 GEs. Its innovative design helps to generate a large number of active S - boxes in fewer rounds which can thwart the linear and differential attacks on the cipher. PICO shows good performance on both the hardware and the software platforms. PICO consumes only 2504 bytes of Flash memory which is less than the ultra-lightweight cipher PRESENT. PICO has a very strong substitution layer (S-box) which not only makes the design robust but also introduces a great avalanche effect. PICO has a strong and compact key scheduling which is motivated by the latest cipher SPECK designed by NSA. PICO consumes 28 mW of dynamic power which is less than the PRESENT cipher (38 mW). The security analysis of PICO and its performance as an ultra-lightweight cipher are presented.

Usefulness of Mining Methods in Knowledge Source Analysis in the Construction Industry
Authors: Gajzler M.
Published: May 2016

The mining methods are classified as the methods of data analysis and the knowledge acquisition and they are derived from the methods of “Knowledge Discovery”. Within the scope of these methods, there are two main variants associated with a form of data, i.e.: “data” and “text mining”. The author of the paper tries to find an answer to a question about helpfulness and usefulness of these methods for the purpose of knowledge acquisition in the construction industry. The very process of knowledge acquisition is essential in terms of the systems and tools operating based on knowledge. Nowadays, they are the basis for the tools which support the decision-making processes. The paper presents three cases studies. The mining methods have been applied to practical problems - the selection of an adhesive mortar coupled with alternative solutions, analysis of residential real estate locations under construction by a developer company as well as support of technical management of a building facility with a large floor area.
Scheduling of Job Resources in Multiunit Projects with the Use of Time I Cost Criteria
Authors: Podolski M.
Published: May 2016

This paper presents a model of scheduling of multiunit construction project based on an NP-hard permutation flow shop problem, in which the considered criterion is the sum of the costs of the works’ execution of the project considering the time of the project as a constraint. It is also assumed that each job in the units constituting the project may be realized in up to three different ways with specific time and cost of execution. The optimization task relies on solving the problem with two different decision variables: the order of execution of units (permutation) and a set of ways to carry out the works in units. The task presented in the paper is performed with the use of a created algorithm which searches the space of solutions in which metaheuristic simulated annealing algorithm is used. The paper presents a calculation example showing the applicability of the model in the optimization of sub-contractors’ work in the construction project.

Authors: Vila-Liante Virtudes , Sánchez-López Verónica , Martínez-Sales Vicenta , Ramón-Nuñez Luis A. , Arellano-Orden Elena , Cano-Ruiz Alejandra , Rodríguez-Martorell Francisco J. , Gao Lin , Otero-Candelera Remedios
Published: May 2016

Background:

Microparticles (MPs) have been shown to be markers of cellular activation and interactions. Pre-analytical conditions such as the centrifugation protocol and sample storage conditions represent an important source of variability in determining MPs values. The objectives of this study were to evaluate the influence of sample storage conditions and centrifugation speed and temperature on the determination of MPs in plasma.

Methods:

Citrate-anticoagulated blood samples obtained from 21 healthy subjects were centrifuged under four different protocols involving different speeds (2500 g or 1500 g) and temperatures (4 °C or 20 °C) to isolate platelet-poor plasma (PPP). The number of MPs in fresh and frozen-thawed PPP were analyzed by flow cytometry, and MPs-mediated procoagulant activity was determined by a thrombin generation test and phospholipid-dependent procoagulant tests.

Results:

The number of MPs and their procoagulant activity were affected by freeze-thaw cycling and centrifugation speed but not by centrifugation temperature. Sample freezing increased MPs number (six-fold) and thrombin generation (four-fold), and decreased clotting time (two-fold). Low centrifugation speed caused an increase in MPs number and a parallel increase in MP-mediated procoagulant activity.

Conclusions:

Sample storage conditions and centrifugation speed are important processing conditions affecting MPs number and activity. Before any study, the protocol for MPs isolation should be optimized to ensure a reliable characterization of MPs, which could provide important information for diagnostic purposes and for understanding the pathogenesis of diseases.
The survival of dental implants with different implant-abutment connection systems
Authors: Szpak Piotr , Szymanska Jolanta
Published: May 2016

The aim of the study was to evaluate the survival of implants with different implant-abutment connection systems, in patients who had two kinds of implants implanted. In total, 240 implants were implanted - 91 implants with conical abutment Morse connection, and 149 with an internal hexagonal connection. During the follow-up period of 3 years and 10 months, the percentage of lost implants with a conical implant-abutment connection was 1.1%. Regarding the implants with hexagonal implant-abutment connection, this figure was 0.7%. Our work shows that there is a need for further research on the survival of dental implants. In this, the influence of other factors should be explored that are related both to the specific implant treatment, as well as to socio-demographic factors

Published: May 2016

With the rapid development of computer technology, gaming has become more popular, and young people spend more and more time playing such games. It is thought that this a major factor responsible for the lowered physical activity of today's society. For a better understanding of the issue, we assessed how many students spend their free time playing video games, and how this form of recreation affects their levels of physical activity. The investigation of the relationship between physical activity and playing computer games was undertaken via a questionnaire containing 16 questions, and this was applied to a representative sample of 138 students drawn from Lublin’s universities. The results of this show that males are more physically active (85% compared to 75% women). However, only 9% men and 13% women train every day. To keep the body in shape, the most common activity for the respondents is aerobics training (approx. 30%), walking and cycling. Such exercise is performed to improve or keep in shape, and as a form of relaxation. However, one third of all respondents play video games, 70% of these are males and only 16% are females. What is more, our results show that there was no correlation between level of physical activity and gaming. In both groups, about 80% of all respondents are physically active. Yet, among the players, there are more overweight people (28%), as compared to 10% in the non-player group. Still, players, in contrast to popular opinion, are more active than non-playing people. No association was found between playing computer games and health problems.

Published: May 2016

Accelerated atherosclerosis and increased cardiovascular events have been extensively documented in patients with end stage chronic kidney disease.

The aim of our work was to find evidence supporting the theory that chronic heart failure (CHF) induces renal function damage. In our work, lipids, apolipoprotein (apo)AI, NTproBNP, hsCRP, lipid hydroperoxide (LPO) and creatinine levels were determined in patients with CHF. A total of 37 patients who were diagnosed with CHF, as well as 15 healthy persons, were recruited for the study. The patients were placed into 2 groups: patients with NYHA class 2 and NYHA class 3. Using routine laboratory methods, NT-proBNP level, and lipids were measured by way of employing a Cobas Integra analyser, while the concentration of hs-CRP was measured by immunonephelometric methods. Moreover, serum LPO concentration was measured using Cayman’s Assay Kit (LPO). The statistical analysis of the obtained results was performed using the nonparametric Kruskal-Wallis test and Spearman’s correlation analysis. Our work demonstrated that the CHF patients had significantly decrease concentration of HDL cholesterol and apoAI, but increased NT-pro-BNP, hsCRP and LPO levels. In all CHF patients, a significant positive correlation between NT-proBNP concentration and creatinine levels, and a significant negative correlation between NT-proBNP concentration and apoAI levels, as well as between concentration of creatinine and apoAI levels, was shown. The study results suggest that variation in the concentration of NT-proBNP, LPO, hsCRP, apoAI, creatinine, in addition to chronic heart failure progression, gradually accompany the progress of chronic renal failure. What is more, the disorders may lead to the occurrence of cardiovascular events, consequently, to patient death.
The stability and degradation kinetics of acetylsalicylic acid in different organic solutions revisited – an UHPLC–ESI-QTOF spectrometry study
Authors: Skibinski Robert , Komsta Lukasz
Published: May 2016

Ultra high performance liquid chromatography (UHPLC), coupled with accurate quadrupole-time-of-flight (Q-TOF) mass spectrometry, was used for the stability study of acetylsalicylic acid within a variety of different organic solutions: methanol, ethanol, propan-2-ol, acetonitrile, tetrahydrofuran and 1,4-dioxane. With the use of gradient elution chromatography and mass spectrometry detection in negative ionization, MS and MS/MS spectra were recorded simultaneously. In addition, quantitative, as well as qualitative analysis was performed during one assay. The stability of acetylsalicylic acid in such solutions was tested at room temperature, in a 12h period. In the work, in all cases, only one main degradation product, salicylic acid, was found. What is more, the work revealed that the degradation of aspirin in the tested organic solutions yields apparent second-order kinetics. The study also demonstrated that acetonitrile and 1,4-dioxane turned out to be the most stable solvents, and an above 80% of initial concentration of acetylsalicylic acid was found in this case. Furthermore, the most popular analytical solvents, methanol and ethanol, were found to be very unstable media. Herein, below 40% of initial concentration of acetylsalicylic acid was seen after 12h. The obtained results were also compared with the degradation of acetylsalicylic acid in a water solution. In this situation, only about 25% of the analyzed compound was resolved to salicylic acid in the same time frame.

Published: May 2016

A rapid, simple and sensitive capillary zone electrophoresis method was developed for the simultaneous determination of amlodipine besylate and telmisartan, in fixed-dose combinations, through the utilization of a UV photodiode array detector. Electrophoretic parameters such as buffer concentration and pH, system temperature, applied voltage and injection parameters, were optimized in order to improve the efficiency of the separation. The best results were obtained when employing fused silica capillary (48 cm length X 50 μm ID) and 50 mM phosphate buffer electrolyte at pH 4.50, + 25 kV applied voltage, as well as 25°C system temperature. The separation was achieved in approximately 3 minutes, with a resolution of 4.90, while the order of migration was amlodipine followed by telmisartan. The analytical performance of the method was verified with regard to linearity, precision and robustness. In addition, the limit of detection and the quantification were calculated.

Published: May 2016

Introduction:

Sleep is an important physiological condition that plays a role in the physical and emotional development of adolescents. The aim of the study is to determine some sleep characteristics of adolescents living in the city of Ribeirão Preto (SP).

Methods:

This is a cross-sectional descriptive study conducted at 14 schools in the city of Ribeirão Preto (SP) including adolescents aged 10–19 years using a questionnaire about sleep habits. The χ2 test was used to determine differences between genders with the aid of the EPI-INFO 7 software, with the level of significance set at p<0.05.

Results:

A total of 535 adolescents (65% girls) were included in the study. Of these, 47.7% studied during the morning period and 10.3% had a job and studied in the evening period. Regarding sleep duration, 242 (45%) slept <9 h per night during week days and 256 (48%) during the weekends (Saturday and Sunday). Of the total number of adolescents studied, 75.5% reported that they went to bed when they felt sleepy, 90% reported delay in falling asleep, 84.3% used some type of electronic equipment before going to sleep, and 44% reported that they woke up during the night. In the morning, 70.3% needed to be awakened, and 44.7% reported a delay in waking up. During daytime, 70% felt somnolent and 34% reported that they slept during the day. Girls reported that they felt more daytime sleepiness (71.3%) and slept more during the day (62.1%) than boys (28.7% and 37.9%, respectively).

Conclusion:

The study showed that almost half the adolescents investigated sleep less than the minimum time considered ideal. Furthermore, most of the adolescents went to the bed when they felt sleepy, used electronic devices before falling sleep, had difficulties falling asleep, need to be awaken in the morning and felt sleepy during the day.
Lutheran Exiles of Christ in the Sixteenth Century
Authors: Osten-Sacken Vera v. der
Published: May 2016

During the sixteenth century Lutheranism experienced expulsion and exile also within the Holy Roman Empire though considerably different from Calvinist or other Protestant experiences of exile. In Lutheranism mainly the theologically educated elite was concerned: professors, parsons, deacons or school assistants. Aside from transconfessional clashes with Catholic or Calvinist authorities conflicts with Lutheran authorities escalated severely thus resulting in the dismissal or resignation of the theologians concerned. With the self-identification as Exul (Christi), that appeared around 1550 and that was still in use until the late eighteenth century, a great number of Lutherans in exile articulated – and claimed – their right to be regarded as upright confessors and living martyrs of the true (Lutheran) doctrine. The focus of this essay is on the cultivation of the experience of exile by these Exules who were an exceptionally belligerent group of theologically educated Lutherans who developed a new understanding of martyrdom in Lutheranism drawing on a theology of the little flock.

Authors: Sotner Roman , Jerabek Jan , Herencsar Norbert , Horng Jiun-Wei , Vrba Kamil , Dostal Tomas
Published: May 2016

This work presents an example of implementation of electronically controllable features to an originally unsuitable circuit structure of oscillator. Basic structure does not allow any electronic control and has mutually dependent condition of oscillation (CO) and frequency of oscillation (FO) if only values of passive elements are considered as the only way of control. Utilization of electronically controllable current conveyor of second generation (ECCII) brings control of CO independent of FO. Additional application of voltage amplifier with variable gain in both polarities (voltage-mode multiplier) to feedback loop allows also important enlargement of the range of the independent FO control. Moreover, our proposal was tested and confirmed experimentally with commercially available active elements (“Diamond transistor”, current-mode multiplier, voltage-mode multiplier) in working range of tens of MHz.

Published: May 2016

In this paper, the selected results of measurements and analysis of the active surfaces of a new generation of coated abrasive tools obtained by the use of focus-variation microscopy (FVM) are presented and discussed. The origin of this technique, as well as its general metrological characteristics is briefly described. Additionally, information regarding the focus variation microscope used in the experiments - InfiniteFocus® IF G4 produced by Alicona Imaging, is also given. The measurements were carried out on microfinishing films (IMFF), abrasive portable belts with Cubitron™ II grains, and single-layer abrasive discs with Trizact™ grains. The obtained results were processed and analyzed employing TalyMap 4.0 software in the form of maps and profiles, surface microtopographies, Abbott- Firestone curves, and calculated values of selected areal parameters. This allowed us to describe the active surfaces of the coated abrasive tools, as well as to assess the possibility of applying the FVM technique in such kinds of measurements.

Map perception: theories and research in the second half of the twentieth century
Authors: Żyszkowska Wiesława
Published: May 2016

Until the 1990s map perception research was one of the main parts of cartography as a scientific discipline. In the last years of the century map perception research fell out of favor as cartographers turned their attention to the new computer technology. In the first decade of the 21th century the problems of map perception became more frequent in cartographic journals.

The article recaps the main problems, theories and research conducted in the twentieth century. The main concepts connected with map perception are discussed: use, utilization, reception and interpretation. These terms are used differently in different research orientations. The author assumes that the terms: reception, reading and perception are unambiguous and perception should be treated as a complex of active and highly interactive processes, leading to identification and understanding of the visible image. The relation of perception research with theory of cartography are presented in three stages of development of the research. In the first, intuitive stage, very important role played eminent cartographers Max Eckert and Karl Peucker, who appreciated the role of human perception in cartography. The second stage began with the research initiated by A.H. Robinson in the 1950s. In the stage perceptual research contributed to the physical aspects of cartographic signs and the psychophysical orientation emerged. Perception has been accepted as an element of cartographic communication theory, modeling theory and cartographic semiotics. The third stage of perceptual research emerged as a result of criticism of empirical research effects. Cartographers turned to methods and theories of cognitive psychology and cognitive orientation was a main paradigm of the research. Perception is perceived as one of the elements of the human cognitive system and considered in the context of higher lever cognitive processes, participating in cartographic information processing. Two methodological approaches can be set apart: theoretical and experimental. In the theoretical approach the processing succession is considered and some models of cartographic processing models were presented. The first decade of the 21st century opens a new stage of perceptual research. It can be named cognitive-digital as the research is based on computer software and is concentrated on cognitive aspects of map perception.
Building a RAPPOR with the Unknown: Privacy-Preserving Learning of Associations and Data Dictionaries
Authors: Fanti Giulia , Pihur Vasyl , Erlingsson Úlfar
Published: May 2016

Techniques based on randomized response enable the collection of potentially sensitive data from clients in a privacy-preserving manner with strong local differential privacy guarantees. A recent such technology, RAPPOR [12], enables estimation of the marginal frequencies of a set of strings via privacy-preserving crowdsourcing. However, this original estimation process relies on a known dictionary of possible strings; in practice, this dictionary can be extremely large and/or unknown. In this paper, we propose a novel decoding algorithm for the RAPPOR mechanism that enables the estimation of “unknown unknowns,” i.e., strings we do not know we should be estimating. To enable learning without explicit dictionary knowledge, we develop methodology for estimating the joint distribution of multiple variables collected with RAPPOR. Our contributions are not RAPPOR-specific, and can be generalized to other local differential privacy mechanisms for learning distributions of string-valued random variables.
Black-Box Accumulation: Collecting Incentives in a Privacy-Preserving Way
Authors: Jager Tibor , Rupp Andy
Published: May 2016

We formalize and construct black-box accumulation (BBA), a useful building block for numerous important user-centric protocols including loyalty systems, refund systems, and incentive systems (as, e.g., employed in participatory sensing and vehicle-to-grid scenarios). A core requirement all these systems share is a mechanism to let users collect and sum up values (call it incentives, bonus points, reputation points, etc.) issued by some other parties in a privacy-preserving way such that curious operators may not be able to link the different transactions of a user. At the same time, a group of malicious users may not be able to cheat the system by pretending to have collected a higher amount than what was actually issued to them.

As a first contribution, we fully formalize the core functionality and properties of this important building block. Furthermore, we present a generic and non-interactive construction of a BBA system based on homomorphic commitments, digital signatures, and non-interactive zero-knowledge proofs of knowledge. For our construction, we formally prove security and privacy properties. Finally, we propose a concrete instantiation of our construction using Groth-Sahai commitments and proofs as well as the optimal structure-preserving signature scheme of Abe et al. and analyze its efficiency.
Don’t Interrupt Me While I Type: Inferring Text Entered Through Gesture Typing on Android Keyboards
Authors: Simon Laurent , Xu Wenduan , Anderson Ross
Published: May 2016

We present a new side-channel attack against soft keyboards that support gesture typing on Android smartphones. An application without any special permissions can observe the number and timing of the screen hardware interrupts and system-wide software interrupts generated during user input, and analyze this information to make inferences about the text being entered by the user. System-wide information is usually considered less sensitive than app-specific information, but we provide concrete evidence that this may be mistaken. Our attack applies to all Android versions, including Android M where the SELinux policy is tightened.

We present a novel application of a recurrent neural network as our classifier to infer text. We evaluate our attack against the “Google Keyboard” on Nexus 5 phones and use a real-world chat corpus in all our experiments. Our evaluation considers two scenarios. First, we demonstrate that we can correctly detect a set of pre-defined “sentences of interest” (with at least 6 words) with 70% recall and 60% precision. Second, we identify the authors of a set of anonymous messages posted on a messaging board. We find that even if the messages contain the same number of words, we correctly re-identify the author more than 97% of the time for a set of up to 35 sentences.

Our study demonstrates a new way in which system-wide resources can be a threat to user privacy. We investigate the effect of rate limiting as a countermeasure but find that determining a proper rate is error-prone and fails in subtle cases. We conclude that real-time interrupt information should be made inaccessible, perhaps via a tighter SELinux policy in the next Android version.
Blogs, Twitter Feeds, and Reddit Comments: Cross-domain Authorship Attribution
Authors: Overdorf Rebekah , Greenstadt Rachel
Published: May 2016

Stylometry is a form of authorship attribution that relies on the linguistic information to attribute documents of unknown authorship based on the writing styles of a suspect set of authors. This paper focuses on the cross-domain subproblem where the known and suspect documents differ in the setting in which they were created. Three distinct domains, Twitter feeds, blog entries, and Reddit comments, are explored in this work. We determine that state-of-the-art methods in stylometry do not perform as well in cross-domain situations (34.3% accuracy) as they do in in-domain situations (83.5% accuracy) and propose methods that improve performance in the cross-domain setting with both feature and classification level techniques which can increase accuracy to up to 70%. In addition to testing these approaches on a large real world dataset, we also examine real world adversarial cases where an author is actively attempting to hide their identity. Being able to identify authors across domains facilitates linking identities across the Internet making this a key security and privacy concern; users can take other measures to ensure their anonymity, but due to their unique writing style, they may not be as anonymous as they believe.
Access Denied! Contrasting Data Access in the United States and Ireland
Authors: Grogan Samuel , McDonald Aleecia M.
Published: May 2016

The ability of an Internet user to access data collected about himself as a result of his online activity is a key privacy safeguard. Online, data access has been overshadowed by other protections such as notice and choice. This paper describes attitudes about data access. 873 US and Irish Internet users participated in a survey designed to examine views on data access to information held by online companies and data brokers. We observed low levels of awareness of access mechanisms along with a high desire for access in both participant groups. We tested three proposed access systems in keeping with industry programs and regulatory proposals. User response was positive. We conclude that access remains an important privacy protection that is inadequately manifested in practice. Our study provides insight for lawmakers and policymakers, as well as computer scientists who implement these systems.

Published: May 2016

With the looming global population crisis, it is more important now than ever that students understand what factors influence population dynamics. We present three learning modules with authentic, student-centered investigations that explore rates of population growth and the importance of resources. These interdisciplinary modules integrate biology, mathematics, and computer-literacy concepts aligned with the Next Generation Science Standards. The activities are appropriate for middle and high school science classes and for introductory college-level biology courses. The modules incorporate experimentation, data collection and analysis, drawing conclusions, and application of studied principles to explore factors affecting population dynamics in fruit flies. The variables explored include initial population structure, food availability, and space of the enclosed population. In addition, we present a computational simulation in which students can alter the same variables explored in the live experimental modules to test predictions on the consequences of altering the variables. Free web-based graphing (Joinpoint) and simulation software (NetLogo) allows students to work at home or at school.
The pro-adhesive and pro-survival effects of glucocorticoid in human ovarian cancer cells
Authors: Yin Lijuan , Fang Fang , Song Xinglei , Wang Yan , Huang Gaoxiang , Su Jie , Hui Ning , Lu Jian
Published: May 2016

Cell adhesion to extracellular matrix (ECM) is controlled by multiple signaling molecules and intracellular pathways, and is pivotal for survival and growth of cells from most solid tumors. Our previous works demonstrated that dexamethasone (DEX) significantly enhances cell adhesion and cell resistance to chemotherapeutics by increasing the levels of integrin β1, α4, and α5 in human ovarian cancer cells. However, it is unclear whether the components of ECM or other membrane molecules are also involved in the pro-adhesive effect of DEX in ovarian cancer cells. In this study, we demonstrated that the treatment of cells with DEX did not change the expression of collagens (I, III, and IV), laminin, CD44, and its principal ligand hyaluronan (HA), but significantly increased the levels of intracellular and secreted fibronectin (FN). Inhibiting the expression of FN with FN1 siRNA or blocking CD44, another FN receptor, with CD44 blocking antibody significantly attenuated the pro-adhesion of DEX, indicating that upregulation of FN mediates the pro-adhesive effect of DEX by its interaction with CD44 besides integrin β1. Moreover, DEX significantly enhanced cell resistance to the chemotherapeutic agent paclitaxel (PTX) by activating PI-3K-Akt pathway. Finally, we found that DEX also significantly upregulated the expression of MUC1, a transmembrane glycoprotein. Inhibiting the expression of MUC1 with MUC1 siRNA significantly attenuated the DEX-induced effects of pro-adhesion, Akt-activation, and pro-survival. In conclusion, these results provide new data that upregulation of FN and MUC1 by DEX contributes to DEX-induced pro-adhesion and protects ovarian cancer cells from chemotherapy.

Among the following breeds of sheep, Merino, Bleu du Maine, Bluefaced Leicester, Dorper, Clan Forest, Suffolk, Texel and Beltex, helminths of two classes (Nematoda and Cestoda) have been registered in Ukraine (Dnipropetrovsk oblast). Among the nematodes there were: parasites of the digestive system Haemonchus contortus (Rudolphi, 1803), Strongyloides papillosus (Wedl, 1856), Nematodirus sp., Trichuris sp. and parasites of the respiratory system Muellerius capillaris (Muller, 1889). In the excrements of small ruminants, eggs of Moniezia expansa (Rudolphi, 1805) (Cestoda) – helminths of the small intestine, were found. Among all studied animals we found S. papillosus. 58.2% of sheep were infested with H. contortus. The lowest indicators of invasion extensivity were registered for parasitism of Trichuris sp. and M. capillaries. Extensivity of Nematodirus invasion did not exceed 16.3%. This indicator for cestodiasis, specifically monieziasis, among sheep was 25,5%. The range of fluctuation in intensivity of nematode invasion was within 7 to 860 eggs/g of excrement. This indicator for Cestoda invasion did not exceed 350 eggs/g. The highest indicators of average invasion were registered for parasitism by S. papillosus and H. contortus. The lowest average indicators of intensity were found for Trichuris. For Nematoda and Muellerius they were 25.0 and 88.9 individuals/g of feces correspondingly. The greatest influence on changes of body weight in sheep was caused by nematodes of the digestive tract Trichuris sp. and of the respiratory organs M. capillaris. The indicators of Trichuris infection level are the lowest in comparison with other registered helminthiases.

El estudio que se presenta evaluó los niveles de autoconcepto físico de un grupo de adolescentes de manera global, en función de sus dimensiones: apariencia física, habilidad física, fuerza, equilibrio, flexibilidad, resistencia y en función del sexo en la población de 12 a 15 años de Jaén, España. La muestra está compuesta por 296 participantes, con una edad media de 13,03 años y un rango de edad entre 12 y 15 años. Se seleccionó como instrumento de medición una adaptación del Cuestionario de Autoconcepto Físico de Marsh y Southerland. Los resultados indicaron que los hombres puntuaron por encima de las mujeres, en la mayoría de los ítems que mostraban aspectos positivos del autoconcepto y por lo contrario, en la mayoría de los ítems que mostraban aspectos negativos del autoconcepto, las mujeres puntuaron por encima de los hombres. Nuestros resultados evidencian diferencias significativas por sexo respecto al autoconcepto físico de los adolescentes, por lo que se encontró una valoración más negativa en el autoconcepto físico de ellas que en los hombres y un mayor interés hacia el ejercicio físico por parte de ellos.

En este escrito se analiza el manejo de la emocionalidad en las estrategias de mercadeo en empresas del sector funerario, destacando el carácter contextual y ambiental del marketing dentro de la cultura como base permeable de la sociedad, sus hábitos, costumbres y rituales. Se partió de un estudio cualitativo usando entrevistas en profundidad y observación; se hizo un acercamiento teórico al marketing emocional y se muestran las relaciones encontradas entre este y las estrategias de mercadeo que están siendo usadas por las empresas funerarias.  Identificando el manejo de la emocionalidad implementado en el sector funerario por medio de “talleres de duelo”; eventos post-mortem de carácter masivo, donde los dolientes asisten a charlas programadas cada tres meses. Este tipo de eventos  por su periodicidad, asisten un número elevado de personas, dificultando que la experiencia sea individual, detallada y que facilite un contacto directo entre el cliente y la empresa.

This paper interprets the Metro Vancouver food localization movement, thorough the lens of the second generation of food sovereignty, with the objective of exploring its economic dimensions. First we promote a theoretical discussion of food sovereignty explaining that it started in a rural setting of the global south as a means to contest the international neoliberal trade system, and how it has adapted in the global north to incorporate consumers. We then discuss the contradictions between British Columbia’s and Metro Vancouver’s food systems. In sequence, we present the results from interviews of the movement’s stakeholders, offering a qualitative analysis. Our findings demonstrate that there are several economic consequences, identifying: i) farmer markets as currently the most significant channel for the commerce of local foods and how they have been responsible for (re)approximating food producers and consumers; also, ii) institutional markets as a next step that can represent a true democratization of good food.

En 2012 se firmó el acuerdo de la Alianza del Pacífico (AP) el cual se ha constituido en una clara respuesta geopolítica al denominado giro a la izquierda de algunos gobiernos en América Latina. En este contexto del accionar político latinoamericano, en las últimas tres décadas, se puede entender con mayor profundidad la aparición de AP como un nuevo esquema de regionalismo abierto que pretende el perfeccionamiento de la zona de libre comercio en los cuatro países que integran el proyecto regional: Chile, Colombia, México y Perú; Este acuerdo surge como un contrapeso del Mercosur y se quiere proyectar en el mediano plazo a un mercado común. Si bien el crecimiento y la estabilidad macroeconómica que se observa en los cuatro integrantes, son los avales de entrada para ser realidad el objetivo propuesto, existen serios obstáculos a vencer en AP para transcender los estadios de integración; el más importante es la baja compatibilización de las aduanas frente a terceros que, hace casi imposible tener en este bloque en el mediano plazo un mercado común regional.
Nietykalność i integralność w projekcie księgi pierwszej Kodeksu cywilnego – analiza prawnoporównawcza

The study examines the issue of extending the proposed wording of article 21 in the draft of book one of the Civil Code on two closely related personal rights – inviolability and integrity. The proposed extension of the contents of the catalogue of personal rights confirms the position of the doctrine to this point in time as regards the need to guarantee the particular protection for individuals and the threat to the personal rights layed out therein. Done in accordance with international acts and documents and ETPC case law, the analysis leads to two main conclusions. First, the concept of integrity is undoubtedly rooted in basic human rights including dignity, freedom, and privacy; and, second, its scope is very broadly interpreted, allowing for a diversity of concepts and forms of integrity to be differentiated. These include biological, genetic, moral, and sexual integrity.

Patients with ESRD undergoing peritoneal dialysis develop progressive peritoneal fibrosis, which may lead to technique failure. Recent data point to Th17-mediated inflammation as a key contributor in peritoneal damage. The leukocyte antigen CD69 modulates the setting and progression of autoimmune and inflammatory diseases by controlling the balance between Th17 and regulatory T cells (Tregs). However, the relevance of CD69 in tissue fibrosis remains largely unknown. Thus, we explored the role of CD69 in fibroproliferative responses using a mouse model of peritoneal fibrosis induced by dialysis fluid exposure under either normal or uremic status. We found that cd69−/−
mice compared with wild-type (WT) mice showed enhanced fibrosis, mesothelial to mesenchymal transition, IL-17 production, and Th17 cell infiltration in response to dialysis fluid treatment. Uremia contributed partially to peritoneal inflammatory and fibrotic responses. Additionally, antibody–mediated CD69 blockade in WT mice mimicked the fibrotic response of cd69−/−
mice. Finally, IL-17 blockade in cd69−/−
mice decreased peritoneal fibrosis to the WT levels, and mixed bone marrow from cd69
−/− and Rag2−/−

γ
c−/− mice transplanted into WT mice reproduced the severity of the response to dialysis fluid observed in cd69
−/− mice, showing that CD69 exerts its regulatory function within the lymphocyte compartment. Overall, our results indicate that CD69 controls tissue fibrosis by regulating Th17-mediated inflammation.
BOTANDO CORPO, (DES)FAZENDO GÊNERO. UMA FERRAMENTA PARA A PESQUISA-INTERVENÇÃO NA EDUCAÇÃO

Published: May 2016

Esse artigo apresenta o percurso de experimentação de uma metodologia de pesquisa-intervenção no campo da educação escolar, com ênfase para o estudo das relações de gênero, sexualidade e gerações em interseccionalidades com outros marcadores sociais de identidade e diferença. Buscou-se com o presente estudo compreender como determinadas posições de sujeito se produzem e quais mecanismos de inteligibilidade e negociações de significados encontram-se presentes em determinados contextos da educação escolar, no mesmo instante em que nos alojamos na perspectiva tática da reversibilidade das formas de objetivação das subjetividades e das desigualdades sociais decorrentes destes discursos através da formulação de ferramentas para a pesquisa-intervenção. Os resultados dessa experimentação metodológica apontam que pesquisa-intervir pode funcionar no sentido de alerta a que estamos ativamente envolvidos na disputa dos processos de significação do corpo, gênero e sexualidade cotidianos.
A CRIANÇA QUEER NO CINEMA E AS SUBVERSÕES DAS NORMAS DE GÊNERO E SEXUALIDADE NA ESCOLA

Esse trabalho pretende discutir, a partir de dois filmes de temática queer, Tomboy e Ma vie en rose, como certas experiências com o corpo, o gênero e a sexualidade podem subverter a norma heterossexual e, com isso, ressignificar o próprio espaço da escola tão marcadamente preconceituoso e excludente. Para isso, o texto compõe-se de dois momentos: no primeiro deles, fazemos uma breve análise de como temos concebido a teorização queer, bem como de que maneira temos percebido suas potencialidades tanto teóricas como políticas no deslocamento da objetificação identitária dos corpos e dos gêneros; no segundo momento, tomamos a experiência cinematográfica para pensar como seria possível a constituição de vivências-afetivo-corporais capazes de deslocar o regime heteronormativo que institui os lugares do masculino e do feminino, bem como estabelecer os reflexos disso no campo escolar/educacional.
