Una joya poco conocida (o elogio de la intuición): La Colonia LukiŠkes en Vilnius (1911-13)
Authors: Ruiz Sánchez Javier
Published: October 2016

Este modesto texto no pretende ser más que un breve apunte, una reivindicación de una de esas pequeñas joyas urbanas apenas conocida y reconocida, generalmente debido a su condición periférica (lejanía geográfica o del centro del debate urbanístico imperante) o a su sólo aparente falta de pretensión culta, sobrepasada en cualquier caso por sus alcances y logros reales. También pretende, y de ahí el subtítulo “elogio de la intuición”, servir de agradecimiento, y nada mejor que para ser incluido en el número con que se alcanza el primer centenar de Ci[ur], al marco que me ha permitido durante todos estos años entrenar la intuición que me permite, entre otras cosas, disfrutar del placer de la experiencia y la práctica del urbanismo. Porque mi descubrimiento de la pequeña joya que aquí presento se produjo, sin mayor expectativa previa, durante un solitario y distraído paseo por la capital lituana entre los dos hoteles que alojaban a los participantes en una conferencia.
Conocimiento ciudadano e investigación urbanística
Authors: Verdaguer Viana-Cárdenas Carlos
Published: October 2016

"No hay otro conocer urbano que la acción de la ciudadanía". Casi bastaría con replicar el contundente título que Mariano Vázquez Espí le puso a su magnífica ponencia del año 2002103 para sintetizar el contenido de la siguiente reflexión, pues dicho título constituye en sí mismo un programa y una declaración de intenciones que suscribo en su totalidad. En su comunicación, Vázquez Espí partía de una reflexión epistemológica ("queremos conocer cómo es que conocemos") para pasar a plantearse los "límites de la técnica" ante el dilema de la toma de decisiones en el marco de una realidad intrínsecamente multidimensional en la que la obtención de soluciones "viables" es matemáticamente posible (mediante optimación vectorial), pero no lo es la selección entre todas las soluciones obtenidas, pues, como él planteaba: "¿quién escoge? ¿el técnico? ¿el azar? ¿hay diferencia?". Tras abordar el carácter "polivalente" del "sujeto de la ciudad", y hacer hincapié en la necesidad de "perder el miedo al conflicto", la exposición culminaba con un alegato a favor de una democracia participativa que ayudase a "que los nuevos sujetos sociales acaben por construir su decisión colectiva".

Published: October 2016

Aim: Grapevine decline caused by wood fungi seriously threatens viticulture worldwide. In Spain, the polyphagous borer Xylotrechus arvicola (Coleoptera, Cerambycidae) is becoming a serious pest in different Qualified Designation of Origin (DOC) wine regions. The aim of the present work was to identify the fungal species growing in the galleries excavated by X. arvicola larvae inside the vine branches and investigate the possible relationship between wood pathogenic fungi and this borer.

Methods and results: Wood samples from branches of Tempranillo vines and Prunus pisardi trees affected by the borer X. arvicola were collected in La Rioja DOC vineyards (Northern Spain) and analyzed for the presence of fungi using both morphological techniques and genetic tools based on Internal Transcribed Spacer 2 (ITS2) sequence. Among the 20 different fungal species/isolates identified, 7 belonged to fungi associated with grapevine decline (esca, Petri disease, and Eutypa dieback), 6 were plant pathogens, 6 were saprophytic and one was entomopathogenic (Beauveria bassiana).

Conclusion: The fact that 65 % of the fungi detected inside X. arvicola galleries belong to species recognized as plant pathogens suggests that this borer, in addition to causing a progressive decay of the branches, could facilitate the transmission of plant diseases, further threatening the vineyards by spreading grapevine decline pathogens.

Significance and impact of the study: The present work represents a first step in recognizing the association between the fungal pathogens associated with grapevine decline and the borer X. arvicola, suggesting a possible role of this insect as a vector in the transmission of these fungi.
Behavioral Finance: A Paradigm Shift
Authors: Yadav Arti , Mushahid Sania
Published: October 2016

The evaluation of behavioral finance attempts to better understand and explain how emotions and cognitive errors influence investors and the decision making process. This study gives an overview of the concept of classical finance and behavioral finance in the beginning and thereafter throws light upon the need and origin of behavioral finance. This paper also presents that how behavioral finance can help investors and financial analysts to better understand the market mechanism of functioning as well as the investment behavior of the stakeholders to this process. Behavioral finance is not a replacement to the classical finance paradigm, but an alternative solution to explain the market inefficiency and the irrational behavior of investor. Also investment decision is seen as a result of an interaction between the investor and the investment environment.

Authors: Nodari Paulo César
Published: October 2016

O presente artigo não tem como objetivo apresentar uma interpretação nova ou inédita da Doutrina das Idéias em Platão. Por isso, apoiado na interpretação de Giovanni Reale dos diálogos platônicos, este trabalho objetiva uma leitura, por assim dizer, geral da doutrina platônica das Idéias. Com tal intento, o artigo se divide fundamentalmente em três partes: 1) o plano da Teoria das Idéias como o primeiro momento da chamada segunda navegação platônica; 2) as características principais das Idéias; 3) o problema da relação entre o mundo das Idéias e o mundo sensível.Abstract: This article does not aim at presenting a new or unpublished interpretation of Plato’s Doctrine of Ideas. Backed up by Giovanni Reale’s interpretation of the platonic dialogues, it intends to propose a general reading of the platonic doctrine of Ideas. Bearing this in mind, the paper is mainly divided in three parts: 1) the level of the Theory of Ideas as the first moment of the so-called platonic second navigation; 2) the main characteristics of the Ideas; 3) the problem of the relationship between the world of Ideas and the sensible world.

Published: October 2016

Antônio Vieira nasceu em Lisboa, no dia 6 de fevereiro de 1608. Veio para o Brasil com sua família em 1614, com destino à Bahia. Entre a Bahia, Pernambuco e o Maranhão, Vieira passou mais da metade de sua vida no Brasil. Em 1623, à revelia dos pais, entrou para o noviciado da Companhia de Jesus. Em seus primeiros tempos na Ordem dos Jesuítas, o noviço se destacou de tal maneira — pela agudeza de espírito, pelo talento literário e conhecimento do latim — que seus superiores o encarregaram de escrever, em 1626, o conjunto dos sucessos relativos à ordem religiosa — a Carta Ânua —, relatório endereçado ao Geral da Companhia, em Roma. Depois de passar oito anos no Colégio dos Jesuítas de Olinda, recebe as ordens sacerdotais, em 1634.
O OLHAR DE JANUS: AS DUAS FACES DA CRÍTICA DE NIETZSCHE À METAFÍSICA
Authors: Mitre Maya
Published: October 2016

Este artigo consiste em uma reflexão sobre o caráter dual e complexo da interpretação de Nietzsche sobre a metafísica. Argumenta-se que as críticas do filósofo não têm por alvo a metafísica em si, mas sua subsistência anacrônica e continuada nos valores e instituições do mundo moderno. A dicotomia entre o mundo sensível e uma dimensão transcendente e superior, embora de incontestável valia em certo momento da história humana, passou a se constituir, na era moderna, num formidável entrave à expressão da vontade de poder do homem e, portanto, à sua sobrevivência enquanto tal.Abstract: This article reflects upon the dual and complex character of Nietzsche’s interpretation of metaphysics. It is argued that the philosopher’s criticisms are not directed at metaphysics as such, but rather at its anachronistic and continued presence in the values and institutions of the modern world. The dichotomy between the world of sense experience and a transcendent and superior realm, though of unquestionable value at a certain point in human history, came to be, in the modern era, a fearsome obstacle to the expression of man’s will to power, and, hence, to his very survival.
A Multi-Fusion Pattern Matching Algorithm for Signature-Based Network Intrusion Detection System
Authors: Naik S Manohar , N Geethanjali
Published: October 2016

Security has become a critical issue in today’s highly distributed and networked systems. Network intrusion detection systems (NIDSs), especially signature-based NIDSs, are being widely deployed in a distributed network environment with the purpose of defending against a variety of network attacks. Most of the commercially available NIDSs are software based and rely on pattern matching to extract the threat from network traffic. The increase in network speed and traffic may make existing algorithms to become a performance bottleneck. Therefore it is very necessary to develop faster and more efficient pattern matching algorithm in order to overcome the troubles on performance of NIDSs. Therefore, we propose a multi fusion pattern matching algorithm for Network Intrusion Detection Systems. The results obtained in percentages from the proposed fusion algorithm given better values in terms processing time in milliseconds than the existing algorithms when data English text are applied to evaluate the fusion performances.
Design Method for Improvement of Transient-State Intersample Output of Multirate Systems Including Integrators
Authors: Kamiya Tomonori ,   Graduate School of Engineering, University of Hyogo, Sato Takao , Araki Nozomu , Konishi Yasuo
Published: October 2016

[abstFig src='/00280005/12.jpg' width='300' text='Comparison of output responses' ] This paper discusses a design method for a multirate system including integrators, where the update interval of the control input is shorter than the sampling interval of the plant output. In such a multirate control system, intersample output might oscillate between sampled outputs in the steady state even if the sampled output converges to the reference input. This is because the control input can be updated between the sampled outputs. In a conventional method, a predesigned control law is extended such that the steady-state ripples are eliminated independent of a discrete-time response. However, the conventional method is invalid when integrators are included in a controlled plant. In this study, a difference operation in discrete time is used to address this issue. Moreover, the transient-state intersample response is improved independent of a pre-designed discrete-time response.
Design and Application of a Data-Driven Expert Controller Based on the Operating Data of a Skilled Worker

Published: October 2016

[abstFig src='/00280005/16.jpg' width='300' text='Schematic of data-driven expert controller' ] In recent years, due to the mass retirement of skilled workers, loss of expertise has emerged as a problem in Japan. Meanwhile, the performance of computer hardware has been drastically improving. Skill-based PID controllers utilizing a database have been proposed as a potential solution to this problem. However, these controllers may not respond to multiple demands of control performance from users because the controller was not considered in the evaluation from the users. As a solution to this problem, an expert controller based on a skilled worker’s operating information with control performance assessments has been proposed. According to the method, I/O data, PID parameters that are estimated using the operating data and evaluation values of the skill of the skilled worker are stored in the database. From this, information vectors with high scores are selected, and a local PID controller is designed in response to the user’s requirements. In the conventional research, the least squares method is applied for estimating the PID parameters from the operating data of the skilled worker, and there are no restrictions on their values. This risks a loss of physical meanings of PID parameters in the case that they have negative values. In this research, an expert controller using particle swarm optimization (PSO) is proposed. In this method, data obtained by human control of a control simulator constructed on a computer is used to estimate human’s skill as PID parameters. Moreover, providing restrictions for the estimation of PID parameters enables them to preserve their physical meanings. In this research, the effectiveness of the proposed expert controller is verified using a control simulator.

Published: October 2016

[abstFig src='/00280005/20.jpg' width='300' text='Near-field touch interface system, NFTIS' ] The purpose of this study is to realize a near-field touch interface that is compact, flexible, and highly accurate. We applied a 3-dimensional image sensor (time-of-flight camera) to achieve the basic functions of conventional touch interfaces, such as clicking, dragging, and sliding, and we designed a complete projector-sensor system. Unlike conventional touch interfaces, such as those on tablet PCs, the system can sense the 3-dimensional positions of fingertips and 3-dimensional directions of fingers. Moreover, it does not require a real touch screen but instead utilizes a mobile projector for display. Nonetheless, the system is compact, with a working distance of as short as around 30 cm. Our methods solve the shadow and reflection problems of the time-of-flight camera and can provide robust detection results. Tests have shown that our approach has a high success rate (98.4%) on touch/hover detection and a small standard error (2.21 mm) on position detection on average for different participants, which is the best performance we have achieved. Some applications, such as the virtual keyboard and virtual joystick, are also realized based on the proposed projector-sensor system.
P-Hacking in Orthopaedic Literature: A Twist to the Tail
Authors: Bin Abd Razak Hamid Rahmatullah , Ang Jin-Guang Ernest , Attal Hersh , Howe Tet-Sen , Allen John Carson
Published: October 2016

Background:

“P-hacking” occurs when researchers preferentially select data or statistical analyses until nonsignificant results become significant. We wanted to evaluate if the phenomenon of p-hacking was evident in orthopaedic literature.

Methods:

We text-mined through all articles published in three top orthopaedic journals in 2015. For anonymity, we cipher-coded the three journals. We included all studies that reported a single p value to answer their main hypothesis. These p values were then charted and frequency graphs were generated to illustrate any evidence of p-hacking. Binomial tests were employed to look for evidence of evidential value and significance of p-hacking.

Results:

Frequency plots for all three journals revealed evidence of p-hacking. Binomial tests for all three journals were significant for evidence of evidential value (p < 0.0001 for all). However, the binomial test for p-hacking was significant only for one journal (p = 0.0092).

Conclusions:

P-hacking is an evolving phenomenon that threatens to jeopardize the evidence-based practice of medicine. Although our results show that there is good evidential value for orthopaedic literature published in our top journals, there is some evidence of p-hacking of which authors and readers should be wary.

Antecedents of IT Governance Effectiveness: An Empirical Examination in Brazilian Firms
Authors: Lunardi Guilherme Lerch , Maçada Antonio Carlos Gastaud , Becker João Luiz , Van Grembergen Wim
Published: October 2016

Although some authors have stated that effective IT governance is crucial for any organization to achieve its corporate goals, little empirical research is available supporting the assumptions regarding the factors that determine the effectiveness of IT governance. This paper analyzes the main IT governance domains (i.e., IT strategic alignment, IT risk management, IT value delivery, IT resource management, and IT performance management) and the presence of several IT governance mechanisms that constitute antecedents of IT governance effectiveness. We used partial least squares (PLS) structural equation modeling to test our hypotheses based on survey data from 87 large Brazilian companies. Our results show IT strategic alignment, IT value delivery, IT risk management, and IT performance management have a positive and significant impact on the effectiveness of IT governance. Further, we found associations of structural, procedural, and relational mechanisms with the main IT governance domains suggesting their adoption can improve IT governance within organizations.

Authors: Das Rituparna , Baidya S
Published: October 2016

Introduction: A study was conducted for six randomly selected designated Microscopy Centre areas of West Tripura District of India with objectives to assess the knowledge regarding Pulmonary Tuberculosis (PTB) and DOTS among the PTB patients and to identify the factors determining the knowledge.Methodology: This cross-sectional study was conducted among 220 PTB patients registered for treatment with DOTS therapy during July 2011 to June 2012.Results: The study showed that 29.10% of the patients had satisfactory knowledge of the disease and its treatment. Only 14.10% patients had the correct knowledge regarding the cause of the disease and 53.60% of the patients had the knowledge regarding the mode of transmission and measures for prevention. Again, 6.40% of the patients had the knowledge regarding the drug dosage schedule and 52.70% patients knew the duration of treatment. Satisfactory knowledge was found to be significantly higher among patients with education level of Higher Secondary or above, and patients who had prior knowledge of tuberculosis [OR-17.60(1.68-183.90)]. Again patients who had less income had 86% [OR-0.14 (0.03-0.64)] less chance of having satisfactory knowledge.Conclusion: The overall knowledge level among the patients is unsatisfactory and there is urgent need of advocating educational activities among the patients.SAARC J TUBER LUNG DIS HIV/AIDS, 2015; 12(1), Page: 1-7

Making Headways
Authors: Shockley Daniel B. , Salinas Julia , Taylor Brian D.
Published: October 2016

This report analyzes the impact of smart card fare payments on transit bus dwell time. Shorter dwell times improve travel speeds and reduce headways, which encourage patronage. First, determinants of dwell time are discussed through a review of existing literature. Data from automatic passenger counters and automatic fare collection systems on Los Angeles, California, Metropolitan Transportation Authority buses are then used to estimate a regression model of dwell time by fare payment type, controlling for other factors, including number of passengers boarding and alighting, wheelchairs, bicycles, bus type and configuration, and service (local, express, etc.). An ordinary least squares regression model estimated with those variables explains 45% of the variance in dwell time. Statistically significant coefficients show that smart card payments contributed roughly 2 s per person to dwell time, while cash or other media contributed about 4 s. Using a smart card to purchase a pass or stored value at the fare box contributed about 8 s. While smart cards contributed less to dwell time than did other forms of fare payment, they were not the largest determinants of dwell times overall. An articulated bus, for example, reduced dwell time compared with conventional buses by 3 s on average and as much as 13 s in crowded conditions; similarly, wheelchair boarding and alighting added as much as 35 s. These findings suggest that smart cards can help reduce delays at stops, but their effects were relatively modest compared with those of other factors known to influence dwell time.
Impact on Bus Ridership from Changes in a Route's Span of Service
Authors: Simmons Jacob , Haas Peter J.
Published: October 2016

Ridership response to changes in a bus route's span of service—the start time of the first trip to the end time of the last trip each day—was examined specifically for hours that were not altered by a change in the span of service. Data were obtained for 39 routes from nine transit agencies in the western United States that experienced changes in the span of service without any other types of changes to enable the largest known analysis of such data from American transit systems. Results demonstrated that bus routes receiving an increase in the span of service experienced a 12.4% increase in ridership during unaltered hours (a 3.4% increase in ridership during unaltered hours after adjusting for systemwide rider-ship changes). Bus routes that received a decrease in the span of service experienced a 0.1% decrease in ridership during unaltered hours (a 1.5% decrease in ridership during unaltered hours after adjusting for systemwide ridership changes). Possible reasons for ridership increases following a span decrease that occurred in some samples were explored. The agency that implemented the largest collection of span increases experienced simultaneously the largest percentage increase in rider-ship during unaltered hours and thereby showed similarity to another large span increase outside the United States, a parallel that indicated a potential synergistic effect warranting additional research. Other factors present in routes that experienced relatively strong ridership responses during unaltered hours are also presented for agencies to consider when possible changes to service spans are evaluated.
Increasing the Speed: Case Study from Santiago, Chile
Authors: Schmidt Alejandro , Muñoz Juan Carlos , Bucknell Christopher , Navarro Matías , Simonetti Carolina
Published: October 2016

Bus operational speed—the average speed experienced by buses, including dwell times at bus stops—is a key issue to public transport users and operators. Rising congestion levels have had a direct impact on public transport’s level of service. This paper presents the results of a case study on measures implemented to increase bus operational speeds in the Santa Rosa main road in Santiago, Chile, one of the most critical points of the Santiago de Chile public transport system. By implementing a variety of operational measures, the authors were able to increase bus operational speeds by up to 130%. They argue that speeds at critical points can be significantly improved by implementing short-term measures, although the improvement depends on the physical and operational conditions of the road.
Characterizing Permanent Deformation of Silty Sand Subgrades by Using a Model Based on Multistage Repeated-Load Triaxial Testing
Authors: Salour Farhad , Rahman Mohammad Shafiqur , Erlingsson Sigurdur
Published: October 2016

A simple model for the prediction of permanent deformation of unbound pavement material was used to characterize the accumulation of permanent deformation of unsaturated silty subgrade soils from multistage repeated-load triaxial (RLT) tests. The model incorporated the time-hardening concept; data obtained from RLT tests with cyclic loading of variable magnitudes, conducted on a single specimen, could be used to calibrate the material model parameters. This feature of the model allowed for characterizing the accumulation of permanent deformation of the material under a wide range of stress conditions. The tests were carried out on two silty sand subgrades and at different moisture contents with pore suction measurements (matric suction) incorporated into the stress state calculations used in the modeling. The shakedown ranges for the permanent deformations for each stress path were calculated, and the material parameters of the predictive models were optimized with the RLT test data. In general, the models performed satisfactorily in capturing the permanent deformation behavior of the selected subgrade materials. The model includes fewer parameters as compared with some existing permanent deformation models and requires reduced testing effort because it is based on results from a multistage RLT test with a single specimen. It can be concluded that the model and the approach have great potential for characterizing and modeling the permanent deformation of subgrade soils.
Permittivity Characterization of Unbound Granular Pavement Materials with a Modified Free-Space Approach
Authors: Muller Wayne B.
Published: October 2016

Moisture has a considerable influence on the structural performance of unbound granular (UBG) pavements. Multioffset ground-penetrating radar has the potential to quantify moisture within these materials by measuring the permittivity of pavement layers. To enable moisture estimates from these field measurements, relationships between permittivity and volumetric moisture are required. This paper describes the use of a modified free-space (MFS) laboratory approach to measure the permittivity of compacted UBG material samples and to develop these relationships. Material samples were compacted within form ply boxes; various density and moisture conditions were targeted. A vector network analyzer was used to measure the phase shift between a fixed pair of ground-coupled dipole antennas as a result of sample insertion and an initial ply sheet reference measurement. Frequency-dependent permittivity values for the samples were then determined over the range of 1.0 to 2.0 GHz on the basis of these measurements. Mean values over this range were then related to the volumetric moisture content of the samples. An indicative moisture–permittivity relationship was proposed on the basis of MFS measurements of samples from several quarries. Overall, the permittivity results from the MFS approach showed reasonably good agreement for samples at higher moisture contents compared with relationships in the literature that are based on time domain reflectometry. However, for drier samples, the MFS permittivity values were higher than the literature predictions. Possible reasons for these differences are discussed, and an overview of the advantages and limitations of using the technique for characterizing UBG materials is given.

Published: October 2016

An experiment was carried to estimate heterotic performances of newly developed test hybrids utilizing CMS system during Rabi 2011 using RCBD design. Five known CMS lines and sixteen developed R-lines were crossed through line × tester analysis. Eighty test hybrids were developed. It is very difficult to find a hybrid earlier to BRRI dhan28 as life cycle of 140 days. Heterosis for days to first flowering varied from -6.23% to 16.35% with a SD of 4.47 meanwhile heterosis for days to 80% flowering varied from -9.24% to 11.04% with a SD of 4.03. Among eighty crosses seventy two were found positive heterosis for days to first flowering but sixty four crosses were found for days to 80% flowering. RG-BU08-016R crosses with IR58025A (-2.68*) and IR62820A (-3.42**) showed significant negative standard heterosis for days to first flowering. Five crosses of IR58025A showed significant negative heterosis with RG-BU 08-005R (-3.42*), RG-BU 08-006R (-5.28**), RG-BU 08-013R (-4.129**), RG-BU 08-016R (-5.78**), RG-BU 08-018R (-4.06*) for days to 80% flowering.

Positive heterosis were recorded for IR58025A with RG-BU 08-007R (26.97**), RG-BU 08-0046R (8.77**) and RG-BU 08-105R (14.44**) for PER and RG-BU 08-018R (42.46**), RG-BU 08-046R (112.30**), RG-BU 08-057R (27.46*) for SER. While two R-lines, RG-­BU 08-013R (25.41**) and RG-­BU 08-057R (7.21*) were found having significant positive heterosis for panicle exertion rate crosses with IR62820A but RG-BU 08-025R (52.82**), RG-BU 08-057R (122.66**) and RG-BU 08-063R (37.38**) were found having significant positive heterosis for SER. IR62820A/RG-BU08-057R showed significant positive heterosis for both panicle and stigma exertion rate. GAN46A/RG­-BU 08-063R (5.65* & 133.02**) was recorded showing significant positive heterosis for both panicle and stigma exertion rate where. But the crosses of IR68888A was not shown exhibiting a great contribution for panicle and stigma exertion rate except RG-BU08-018R (25.94**).

Ten chilli (Capsicum frutescens L.) genotypes were subjected to an experiment for analysis of stability and genotype-environment interaction in randomized complete block design with four environments using additive main effect and multiplicative interaction (AMMI) model. Parameters for experimentation were number of fruits per plant, fruit diameter, leaf area index, fruit length without panicle, number of seeds per fruit and individual plant fruit yield. A significant mean sum of square due to Genotype (G), Environment (E) and G × E interaction for all the characters was showed by combined ANOVA, suggested differential responses of genotypes in different environments. The AMMI biplots for yield indicated that, BD-2059 and Bogura Jatt were stable across the environments. Genotype Kalo Dhawna morich had positive interaction effect was better suited to favourable environment for most of the traits. According to AMMI characterisation, Env-2 was found highly favourable for better expression of the studied traits for all the genotypes.
MORPHO-PHYSIOLOGICAL AND BIOCHEMICAL TRAIT BASED SELECTION OF WHEAT GENOTYPES FOR DROUGHT TOLERANCE
Authors: Raffi S. A. , Asaduzzaman M.
Published: October 2016

Drought stress is now become the most important abiotic stress for wheat in Bangladesh. Rabi season often compromised wheat production by imposing drought stress. Therefore, it has been a priority to develop drought tolerant wheat variety for Bangladesh. However, the lack of genetic variability for drought tolerance in wheat has been a major bottleneck for developing drought tolerance wheat variety. The present investigation was carried out in an aim to evaluate several exotic and locally cultivated wheat genotypes for drought tolerance based on morpho-physiological and biochemical traits. Experiment was carried out at the net house of Field Laboratory of Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh with seven replications in a RCBD design. Ten locally cultivated and exotic wheat genotypes were grown under control (100% field capacity) and drought (30% field capacity) conditions. Genotypes used in the study were identified with different types of drought tolerance mechanisms, viz., Berkut for earliness, Shatabdi for grain weight, BARI Gom 26 for spike and grain number, along with Vorobey, Berkut for enhanced biosynthesis of proline, Sokoll for undamaged leaf Chlorophyll content and relative water content, Sakha8, Gaurav, Sonalika and Shatabdi for membrane thermostability; Sakha8 and Sourav for improved stress tolerance index. The genotypes screened out with different traits related to drought tolerance can be utilized as gene source for future breeding programs.

INTRODUCTION: The Motion Sickness Assessment Questionnaire (MSAQ) was developed in order to assess the multiple dimensions of the motion sickness syndrome (gastrointestinal, central nervous system, peripheral, and sopite-related symptoms). The aim of this study was to evaluate
the psychometric properties of the Greek version of the MSAQ.METHODS: The MSAQ was translated into Greek and then translated back into English. Minor differences between the two texts were corrected. The Greek version was then administered to male subjects before and after nauseogenic
motion stimulation. With the use of a motor driven rotating chair, the subjects were exposed to Coriolis cross-coupling stimulation. A battery of statistical tests was used to evaluate the psychometric properties of the MSAQ.RESULTS: There were 112 subjects who participated. Internal
consistency, measured with Cronbach's alpha coefficient, was excellent for the total scale and subscales. The test-retest evaluation was done with Pearson's coefficient and Bland-Altman's plot for the total score and subscales and showed statistically significant results. Mean total MSAQ score
was 19.04 before the exposure and 33.46 after the exposure, which was statistically significant.CONCLUSION: Results suggest the Greek-MSAQ is a valid instrument with satisfactory internal consistency, reliability, reproducibility, validity, and responsiveness and can be used in
future studies of motion sickness in Greek speaking populations.Kousoulis P, Pantes A, Alevetsovitis G, Fydanaki O. Psychometric properties of the Greek version of the Gianaros Motion Sickness Assessment Questionaire. Aerosp Med Hum Perform. 2016; 87(11):954–957.

INTRODUCTION: Flight-induced neck pain is common in high performance jet pilots, with incidents frequently attributed to high Gz flight maneuvers. The additional load of helmet-mounted night vision goggles (NVG) is believed to increase the risk, possibly from neck
muscle strain in counteracting muscles. Hence, the aim was to investigate the effect of NVG on neck muscle strain as well as on the activity level distribution through a simulated flight session in air force pilots.METHODS: In this post hoc randomized crossover trial, four senior
air force pilots each completed two identical 1.5-h dynamic flight simulations in a human centrifuge: one with a standard helmet and NVG, and one with a standard helmet only. Simulations included repeated exposure to 3–7 Gz, during which neck muscle activity was recorded bilaterally
from the anterior neck, the upper and lower posterior neck, and the upper shoulders. The number of muscle activities surpassing 50% of maximum voluntary electrical activity (MVE) and total time of activity at each MVE percentile were compared between NVG and control flights.RESULTS:
There was no overall effect in number of neck strain activities between NVG and control flights; however, significantly more activities emerged in the anterior neck. In addition, MVE percentile data showed a tendency of higher activity in the lower posterior neck during NVG flights.CONCLUSIONS:
The results showed that the additional load of helmet-mounted NVG increases neck muscle strain in anterior stabilizing muscles, indicating that the inertia of head-worn NVG elevates the risk of flight-related neck pain.Pousette MW, Lo Martire R, Linder J, Kristoffersson M, Äng BO.

Published: October 2016

BACKGROUND: Arterial gas embolism (AGE) is a rare condition in the flying community most often only ever seen in flight while operating at high altitude or incidents involving hypobaric chambers. This article describes a severe case of AGE that occurred in a pilot of a fourth
generation fighter aircraft at ground level. The environmental control system (ECS) malfunctioned, causing an overpressurized cockpit and a subsequent explosive decompression when the pilot opened the canopy to egress.CASE REPORT: The ECS onboard fourth generation fighter aircraft
is composed of many computer-controlled subsystems. When these components fail, the system can potentially overpressurize the cockpit. Combined with opening the canopy without prior venting, this overpressurization can lead to a situation akin to a diver surfacing too quickly. A pilot experienced
this scenario and subsequently developed symptoms of arterial gas embolization—one form of decompression illness (DCI). We reviewed the design of the environmental control system and recommend that the cockpit must be slowly depressurized to decrease risk of injury from rapid decompression.DISCUSSION:
Literature review showed three similar cases of ground-based overpressurization causing AGE symptoms, although these cases were maintenance personnel intentionally testing aircraft cabin integrity and not associated with aircraft intending flight.7 The lessons learned from this
case can be used to identify and hopefully prevent severe DCI from ground level cockpit overpressurization and to further general understanding of aircraft ECS.Zhang JX, Berry JR, Beckstrand DP. Explosive decompression with resultant air gas embolism in a fourth generation fighter at

Published: October 2016

To measure the pushing distance of a hydraulic-powered roof support, and reduce the cost from a non-reusable displacement sensor embedded in pushing a hydraulic cylinder, an inertial sensor is used to measure the pushing distance, and a Kalman filter is applied to process the inertial data. To obtain better estimation performance, an improved fruit fly optimization algorithm (IFOA) is proposed to tune the parameters of the Kalman filter, processing noise covariance Q and observation noise covariance R. The key procedures of the proposed method, including state-space model, fitness function, and Kalman filter implementation, are presented. Finally, an artificial signal is utilized to verify the feasibility of the proposed method, and the tuning results of other algorithms, particle swarm optimization (PSO), genetic algorithm (GA), basic FOA, and 3D-FOA are compared. The proposed method is also applied in the pushing distance estimation scenario. The simulation and application results prove the effectiveness and superiority of the proposed method.

Published: October 2016

The malformation of sheet metal tapping screw threads in the screw threading process increases the cost of screw threading dies and their maintenance. Die factories do not reveal their screw threading die design techniques, so production and maintenance processes are established by trial-and-error or worker experience and passing down such techniques and documenting quality control is difficult. In this study, screw thread forming design and process analysis were carried out by combining computer-aided design software with computer-aided metal forming analysis software. Simulation results were verified in an actual forming process. The sheet metal tapping screw forging size error was less than 0.90%, except at a sharp angle, which was associated with an error of 3.075%, thereby demonstrating the accuracy of the simulated forming process. The numerical analysis process can be utilized to shorten forming development time; to reduce the number of die tests, and to improve product quality and die service life, reducing the cost of development and promoting the overall competitiveness of the company.

Complicated environmental problems inevitably arise when technology advances. One major environmental problem is the presence of electromagnetic radiation. Long-term exposure to electromagnetic radiation can damage people’s health in many ways. Therefore, this study proposes producing composite boards with electromagnetic shielding effectiveness and thermal insulation by utilizing the structures and properties of materials. Different combinations of flame-retardant polyester fiber (FR fiber), recycled far-infrared polyester fiber (FI fiber), and 4D low-melting-point fibers (LM fiber) were made into flame-retardant and thermally insulating matrices. The matrices and carbon fiber (CF) woven fabric in a sandwich-structure were needle-punched in order to be tightly compact, and then circularly heat dried in order to have a heat set and reinforced structure. The test results indicate that Polyester (PET)/CF composite boards are mechanically strong and have thermal insulation and electromagnetic shielding effectiveness at a frequency between 0.6 MHz and 3 GHz.

Published: October 2016

Supply networks existing today in many industries can behave as complex adaptive systems making them more difficult to analyze and assess. Being able to fully understand both the complex static and dynamic structures of a complex adaptive supply network (CASN) are key to being able to make more informed management decisions and prioritize resources and production throughout the network. Previous efforts to model and analyze CASN have been impeded by the complex, dynamic nature of the systems. However, drawing from other complex adaptive systems sciences, information theory provides a model-free methodology removing many of those barriers, especially concerning complex network structure and dynamics. With minimal information about the network nodes, transfer entropy can be used to reverse engineer the network structure while local transfer entropy can be used to analyze the network structure’s dynamics. Both simulated and real-world networks were analyzed using this methodology. Applying the methodology to CASNs allows the practitioner to capitalize on observations from the highly multidisciplinary field of information theory which provides insights into CASN’s self-organization, emergence, stability/instability, and distributed computation. This not only provides managers with a more thorough understanding of a system’s structure and dynamics for management purposes, but also opens up research opportunities into eventual strategies to monitor and manage emergence and adaption within the environment.
