A methodolgy for evaluating the structure-borne road noise prior to a prototype vehicle using direct force measured on a suspension rig
Authors: Song David P. , Min Dongwoo , Kang Yeon June , Cho Munhwan , Kim Hyoung Gun , Ih Kang Duck
Published: June 2016

Numerous previous studies have been conducted on quantifying road noise through transfer path analysis (TPA) using the matrix inversion and the dynamic stiffness methods. However, the matrix inversion method is a calculation that always contains error, even when treated with the best
condition number found by trial and error iteration to match the calculation SPL (sound pressure level) to measured SPL. Furthermore, the caveat of the dynamic stiffness method is that it requires accurate dynamic stiffness value up to the frequency range of interest, which, in reality, is
rarely available and is challenging to obtain. Therefore, TPA using these two methods is only possible when a complete vehicle is available. For the sake of cost and time reduction, circumventing these limitations is crucial within the vehicle production period. The main focus of the present
study is to directly obtain the operational forces at the suspension mounting points neglecting the effect of the vehicle body through a special suspension rig. The suspension rig is verified through a comparative analysis with the actual baseline vehicle measurement up to 250 Hz. In addition,
an example approach for finding suspension's NVH performance improving factor using the rig benchmarking technique is introduced.
Species‐rich and polyploid‐poor: Insights into the evolutionary role of whole‐genome duplication from the Cape flora biodiversity hotspot
Authors: Oberlander Kenneth C. , Dreyer Léanne L. , Goldblatt Peter , Suda Jan , Linder H. Peter
Published: June 2016

PREMISE OF THE STUDY:

Whole‐genome duplication (WGD) in angiosperms has been hypothesized to be advantageous in unstable environments and/or to increase diversification rates, leading to radiations. Under the first hypothesis, floras in stable environments are predicted to have lower proportions of polyploids than highly, recently disturbed floras, whereas species‐rich floras would be expected to have higher than expected proportions of polyploids under the second. The South African Cape flora is used to discriminate between these two hypotheses because it features a hyperdiverse flora predominantly generated by a limited number of radiations (Cape clades), against a backdrop of climatic and geological stability.

METHODS:

We compiled all known chromosome counts for species in 21 clades present in the Cape (1653 species, including 24 Cape clades), inferred ploidy levels for these species by inspection or derived from the primary literature, and compared Cape to non‐Cape ploidy levels in these clades (17,520 species) usingGtests.

KEY RESULTS:

The Cape flora has anomalously low proportions of polyploids compared with global levels. This pattern is consistently observed across nearly half the clades and across global latitudinal gradients, although individual lineages seem to be following different paths to low levels of WGD and to differing degrees.

CONCLUSIONS:

This pattern shows that the diversity of the Cape flora is the outcome of primarily diploid radiations and supports the hypothesis that WGD may be rare in stable environments.

Monotonicity and the limits of disharmony
Authors: Rebrus Péter , Törkenczy Miklós
Published: June 2016

The attested front/back harmony systems are monotonic in the sense thatthe harmony function that assigns the values front and back to suffixes ingiven harmonic stem contexts is subject to a constraint that only permitscontiguous patterns of values on a universally fixed scale of harmoniccontexts (ranging from the prototypical back harmony context [...B]_ tothe prototypical front one [...F]_ ). We argue that monotonicity alsoconstrains variation (harmony patterns involving the harmonic valuefront/back) and show that in Hungarian the harmonic properties of a stem(front, back, variable front/back) are inherited by the forms derived fromthe stem by inflection or derivation. This paradigm uniformity effect(Harmonic Uniformity) results in subpatterns of front/back harmony whichalso conform to monotonicity. We demonstrate this using frequency datafrom a corpus study.

Authors: Ružinskas Andrius , Bulevičius Matas , Sivilevičius Henrikas
Published: June 2016

Snow and ice cause considerable traffic problems on roads and streets in the winter period. Timely and effective removal of these problems can prevent major car accidents. This paper presents an analysis of the efficiency of Deicing Materials (DMs) used by the Lithuanian road maintenance agencies. Five different DMs were studied by performing ice melting tests in the laboratory. DMs were evenly spread on the formed ice samples taking the same amount of grains of uniform size. The ice mass dissolved by each DM was determined at different durations of melting action, ranging from 4 to 120 min, and at different ambient temperatures, ranging from –20 to –3 °C. The obtained results of each DM were analysed, and all the tested materials were compared under different temperature conditions. In addition, the deicing speed of each DM was calculated, and the DM was categorized according to the efficiency performance. A comparison of tested DM efficiencies was carried out, and the price of one percent of melted ice was determined.
EFFECT OF ROAD SURFACE DEFORMATIONS ON LATERAL LANE UTILIZATION AND LONGITUDINAL DRIVING BEHAVIOURS
Authors: Aydin Metin Mutlu , Topal Ali
Published: June 2016

Various road surface deformations generally occur on urban and rural roads due to infrastructure, superstructure deficiencies and excessive heavy vehicle loads. In addition to driver-based errors, many accidents happen due to these mentioned surface deformations. This study aims to present lateral lane utilization and longitudinal driving behaviours on a two-lane deformed road. The effect of deformation on the tendency of drivers’ lane selection, lane utilization, and the movement in traffic flow will also be determined. For this purpose, parameters such as lateral position, speed, acceleration/deceleration and location data of vehicles travelling through four different deformation zones on a two-lane road in Izmir (Turkey), were collected. Based on the fact that in ideal conditions, distribution of lateral positions of vehicles in a lane is similar to normal distribution. The collected data was evaluated with chi-square (χ2) goodness of fit test to see if they are fit to normal distribution or not. This study concluded that if a deformation zone has wider area and less depth, it will be less effective on lateral lane utilization of vehicles. It was also obtained from the results that variation in other parameters such as deformation type, depth and height are associated with the lateral lane utilization of drivers. Additionally, the drivers’ characteristics such as perception and aggressiveness are seen as the most important factors influencing the longitudinal vehicle behaviours while passing through the deformation zones.

ULTRAVIOLET EMISSION LINES OF Si ii IN QUASARS—INVESTIGATING THE “Si ii DISASTER”
Authors: Laha Sibasish , Keenan Francis P. , Ferland Gary J. , Ramsbottom Catherine A. , Aggarwal Kanti M.
Published: June 2016

The observed line intensity ratios of the Si ii
λ1263 and λ1307 multiplets to that of Si ii
λ1814 in the broad-line region (BLR) of quasars are both an order of magnitude larger than the theoretical values. This was first pointed out by Baldwin et al., who termed it the “Si ii disaster,” and it has remained unresolved. We investigate the problem in the light of newly published atomic data for Si ii. Specifically, we perform BLR calculations using several different atomic data sets within the CLOUDY modeling code under optically thick quasar cloud conditions. In addition, we test for selective pumping by the source photons or intrinsic galactic reddening as possible causes for the discrepancy, and we also consider blending with other species. However, we find that none of the options investigated resolve the Si ii disaster, with the potential exception of microturbulent velocity broadening and line blending. We find that a larger microturbulent velocity (

) may solve the Si ii disaster through continuum pumping and other effects. The CLOUDY models indicate strong blending of the Si ii
λ1307 multiplet with emission lines of O i, although the predicted degree of blending is incompatible with the observed λ1263/λ1307 intensity ratios. Clearly, more work is required on the quasar modeling of not just the Si ii lines but also nearby transitions (in particular those of O i) to fully investigate whether blending may be responsible for the Si ii disaster.

Authors: Santos Beatriz Sousa , Cardoso João , Ferreira Beatriz Quintino , Ferreira Carlos , Dias Paulo
Published: June 2016

Gesture-based 3D interaction has been considered a relevant research topic as it has a natural application in several scenarios. Yet, it presents several challenges due to its novelty and consequential lack of systematic development methodologies, as well as to inherent usability related problems. Moreover, it is not always obvious which are the most adequate and intuitive gestures, and users may use a variety of different gestures to perform similar actions. This chapter describes how spatial freehand gesture based navigation methods were developed to be used in virtual walkthroughs meant to be experienced in large displays using a depth sensor for gesture tracking. Several iterations of design, implementation, user tests, and controlled experiments performed as formative and summative evaluation to improve, validate, and compare the methods are presented and discussed.

Published: June 2016

A major area of interest within the fields of human-computer interaction (HCI) and human-robot interaction (HRI) is user feedback. Previous work in HCI has investigated the effects of error feedback on task efficiency and error rates, yet, these studies have been mostly restricted to comparisons of inherently different feedback modalities, for example auditory and visual, and as such fail to acknowledge the many possible variations within each of these modalities, some of which being more effective than others. This chapter applies a user-centered approach to investigating feedback modalities for robot teleoperation by naïve users. It identifies the reasons why novice users need feedback when demonstrating novel behaviors to a teleoperated industrial robot and evaluates both various feedback modalities designed to prevent errors and, drawing on document design theory, studies different kinds of visual presentation regarding their effectiveness in the creation of legible error feedback screens.
Organizing Contextual Data in Context Aware Systems
Authors: Mahmud Umar
Published: June 2016

Context aware systems strive to facilitate better usability through advanced devices, interfaces and systems in day to day activities. These systems offer smart service discovery, delivery and adaptation all based on the current context. A context aware system must gather the context prior to context inference. This gathered context is then stored in a tagged, platform independent format using Extensible Markup Language (XML) or Web Ontology Language (OWL). The hierarchy is enforced for fast lookup and contextual data organization. Researchers have proposed and implemented different contextual data organizations a large number of which has been reviewed in this chapter. The chapter also identifies the tactics of contextual data organizations as evident in the literature. A qualitative comparison of these structures is also carried out to provide reference to future research.
HCI and E-Learning
Authors: Obilade Titilola T.
Published: June 2016

This chapter developed a framework for evaluating e-learning for use in Human Computer Interaction (HCI). A systems approach was used in the study; input, processes and output. It discussed the different assumptions about how people learn; behaviorism, cognitivism and constructivism. Further, it examined the common threads in the definitions of e-learning and the literature on evaluation of e-learning models. Nine categories of evaluation of e-learning were identified but five were reviewed because the remaining four overlapped. Two separate evaluations were reviewed under each category, making a total of ten reviews. The reviews showed that the evaluations were not conducted in the same way even within the same category making comparisons difficult. The framework was developed from the highlights in the review. The developed framework can be used to evaluate different e-learning modules along common lines making it easy to compare evaluations. It is hoped that over the next few years, a consistency in evaluations of e-learning would be achieved for use in HCI.

Recent economic crisis has shown that classical approach to individual and local product oriented company is not sustainable in modern economic reality. Possible solution lies in high degrees of both specialization and flexibility product oriented small and medium-sized interchangeable production systems. According to that new wave, the main idea is based on exploring and testing of new possible designs and ways of control of human-computer interfaces for remote control of complex distributed manufacturing systems. Herein, the proposed remote system with Wall interface, video beam presentation mode and using group work enables producers in manufacturing sector to offer a product, through outsourcing manufacturing process and system in a global chain, utilizing ubiquitous computing systems and virtual and networked enterprises concepts, for anywhere-anytime control and give benefits to education sector, too, since students can dynamically interact with a real process to get a remote experimental practice, guaranteeing the availability of lab resource.

Published: June 2016

Assistive environments are primarily designed to support the healthy and independent living of ageing people. Elderly are often perceived as being resistant to technology; in reality, many of them are willing to accept novel digital technologies into their lives, and to take advantage of what technology has to offer. The “not worth it” impression, on the other hand, is more likely to be triggered by unusable interfaces, that prevent the older users from perceiving technology as both usable and useful. This motivates the need of investigating suitable guidelines for the design of user-system interfaces in the field of smart assistive environments, for which elderly are the typical target users. Focusing on two specific physical user-system interfaces, i.e. smart TVs and touchscreen devices, this chapter discusses the requirements that a design for older users has to address. The theoretical discussion is supported by experimental results gained from an Ambient Assisted Living project carried out by the authors, discussed as a use case in the last part of the chapter.

Stroke is the leading cause of disability that influences the quality of people's daily life. As such, an effective method is required for post-stroke rehabilitation. Research has shown that a robot is a good rehabilitation alternative where conventional robotic assistive system is encoded program by the robot expertise. The major drawback of this approach is that the lack of voluntary movement of the patient may affect the proficiency of the recovery process. Ideally, the robotic assistive system should recognize the intended movement and assist the patient to perform and make the training exercises more effective for recovery process. The electromyography based robotics assistive technology would enable the stroke patients to control the robot movement, according to the user's own strength of natural movement. This chapter briefly discusses the establishment of mathematical models based on artificial intelligent techniques that maps the surface electromyography (sEMG) signals to estimated joint torque of elbow for robotic assistive system.
Identity Assurance through EEG Recordings
Authors: Zanin Massimiliano , Papo David
Published: June 2016

The problem of identity assurance, i.e. determining if a claimed identity can be trusted, has been gaining relevance in the last decade, due to the increasing use of on-line services. While this trend can be seen for many biometric sensors, very few studies have considered the use of brain electric signals. This contribution proposes a first solution, based on the reconstruction of motifs (patterns of connectivity between three electroencephalographic sensors) and on the assessment of their stability across different trials for a single subject. Results indicate that, although computationally costly, this approach is promising in terms of the classification scores obtained.
An Introduction to the Basic Concepts in QSAR-Aided Drug Design
Authors: Hamzeh-Mivehroud Maryam , Sokouti Babak , Dastmalchi Siavoush
Published: June 2016

The need for the development of new drugs to combat existing and newly identified conditions is unavoidable. One of the important tools used in the advanced drug development pipeline is computer-aided drug design. Traditionally, to find a drug many ligands were synthesized and evaluated for their effectiveness using suitable bioassays and if all other drug-likeness features were met, the candidate(s) would possibly reach the market. Although this approach is still in use in advanced format, computational methods are an indispensable component of modern drug development projects. One of the methods used from very early days of rationalizing the drug design approaches is Quantitative Structure-Activity Relationship (QSAR). This chapter overviews QSAR modeling steps by introducing molecular descriptors, mathematical model development for relating biological activities to molecular structures, and model validation. At the end, several successful cases where QSAR studies were used extensively are presented.
Ligand- and Structure-Based Drug Design of Non-Steroidal Aromatase Inhibitors (NSAIs) in Breast Cancer
Authors: Jha Tarun , Adhikari Nilanajn , Halder Amit Kumar , Saha Achintya
Published: June 2016

Aromatase is a multienzyme complex overexpressed in breast cancer and responsible for estrogen production. It is the potential target for designing anti-breast cancer drugs. Ligand and Structure-Based Drug Designing approaches (LBDD and SBDD) are involved in development of active and more specific Nonsteroidal Aromatase Inhibitors (NSAIs). Different LBDD and SBDD approaches are presented here to understand their utility in designing novel NSAIs. It is observed that molecules should possess a five or six membered heterocyclic nitrogen containing ring to coordinate with heme portion of aromatase for inhibition. Moreover, one or two hydrogen bond acceptor features, hydrophobicity, and steric factors may play crucial roles for anti-aromatase activity. Electrostatic, van der Waals, and p-p interactions are other important factors that determine binding affinity of inhibitors. HQSAR, LDA-QSAR, GQSAR, CoMFA, and CoMSIA approaches, pharmacophore mapping followed by virtual screening, docking, and dynamic simulation may be effective approaches for designing new potent anti-aromatase molecules.

Published: June 2016

Human papilloma viruses (HPVs) have been acknowledged to be the leading risk factor of cervical intra-epithelial lesion creation (CIN) and cervical cancer development (CxCa). Many different techniques have been created and utilized in HPV detection and monitoring with a vast amount of them being commercialized and few of them integrated in official screening strategies. A growing trend for DNA typing of the 14 most commonly accepted high risk HPV types has been introduced, supporting that in many cases molecular testing could replace classic morphologic diagnostic routines, even though DNA detection has lower specificity than other molecular and morphology tests. However, there have been limited attempts in combining data from all different techniques to provide efficient patient triaging schemes, since, apart from the obvious increase of patient cost, the amount of data and its interpretation in patient management has been impossible. Complex computer based clinical support decision systems, many of which are based on artificial intelligence may abolish these limitations.

Integrated in Silico Methods for the Design and Optimization of Novel Drug Candidates
Authors: Minovski Nikola , Novič Marjana
Published: June 2016

Although almost fully automated, the discovery of novel, effective, and safe drugs is still a long-term and highly expensive process. Consequently, the need for fleet, rational, and cost-efficient development of novel drugs is crucial, and nowadays the advanced in silico drug design methodologies seem to effectively meet these issues. The aim of this chapter is to provide a comprehensive overview of some of the current trends and advances in the in silico design of novel drug candidates with a special emphasis on 6-fluoroquinolone (6-FQ) antibacterials as potential novel Mycobacterium tuberculosis DNA gyrase inhibitors. In particular, the chapter covers some of the recent aspects of a wide range of in silico drug discovery approaches including multidimensional machine-learning methods, ligand-based and structure-based methodologies, as well as their proficient combination and integration into an intelligent virtual screening protocol for design and optimization of novel 6-FQ analogs.

Published: June 2016

Breast cancer incidence and mortality rates are of concern among Latin American women, mainly due to the growing prevalence of this disease and the lack of compliance to proper breast cancer screening and treatment. Focusing on Venezuelan women and the challenges and barriers that interact with their health communication, this paper looks into issues surrounding women's breast cancer, such as the challenges and barriers to breast cancer care, the relevant ethics and responsibilities, the right to health, breast cancer risk perception and risk communication, and the media interventions that affect Venezuelan women's perceptions and actions pertaining to this disease. In particular, it describes an action-oriented research project in Venezuela that was conducted over a four-year period of collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include positive indications on more effective interactions between physicians and patients, increasing satisfactions about issues of ethical treatment in providing healthcare services, more sufficient and responsible media coverage of breast cancer healthcare services and information, a widely supported declaration for a national response against breast cancer in Venezuela, and the creation of a code of ethics for the Venezuelan NGO that led the expansion of networking in support of women's breast cancer healthcare.
Risk, Activism, and Empowerment
Authors: Eid Mahmoud , Nahon-Serfaty Isaac
Published: June 2016

The prevalence of breast cancer in Venezuela is particularly alarming, which is attributed to healthcare inequalities, low health literacy, and lagging compliance with prevention methods (i.e., screening and mammography). While the right to health is acknowledged by the Venezuelan constitution, activism beyond governmental confines is required to increase women's breast cancer awareness and decrease mortality rates. Through the development of social support and strategic communicative methods enacted by healthcare providers, it may be possible to empower women with the tools necessary for breast cancer prevention. This paper discusses issues surrounding women's breast cancer, such as awareness of the disease and its risks, self-advocacy, and the roles of activists, healthcare providers, and society. Specifically, it describes a four-year action-oriented research project developed in Venezuela, which was a collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include higher levels of awareness and interest among community members and organizations to learn and seek more information about women's breast cancer, better understandings of the communicated messages, more media coverage and medical consultations, increasing positive patient treatments, expansion of networking of NGOs, as well as a widely supported declaration for a national response against breast cancer in Venezuela.

Published: June 2016

This article provides empirical evidence on the price and unit sales volume patterns of mobile handsets and mobile technologies, using data on the Finnish market. The prices and sales are studied on product category, product model, and product feature levels. The results show how the dynamic of prices and sales changed after the proliferation of smartphones. Otherwise, the dynamics seem to be relatively systematic supporting the use of simple assumptions in practical estimations. The median price of handset models decreases linearly, from 89% of the introduction price at peak sales in the fifth sales month to 47% in in two years. For mobile handset features, a decreasing price pattern was also identified. After a 10% market share is reached, the decrease is on average 30 Euros per 10% market share change. The prices at feature takeoff were identified to be on average at 58% of introduction price.
A New Timestamp Digital Forensic Method Using a Modified Superincreasing Sequence
Authors: Cho Gyu-Sang
Published: June 2016

This paper proposes a new digital forensic method using a modified superincreasing sequence. Timestamp changes by file commands in Windows NTFS file system are used for identifying what commands were executed and are a useful and a logical way for performing digital forensics. A superincreasing sequence is modified for the timestamp change patterns to make each timestamp pattern have a distinct value. The method has two functions; one is a timestamp change check function and the other is a forensic evaluation function. The former checks differences of timestamps between before and after command execution, and the latter produces a characteristic output by applying ten kinds of timestamp change patterns. According to the characteristic output, the kind of command that is executed is identified. By virtue of adopting the modified superincreasing sequence, the evaluation function could produce distinct characteristic output values and thereby provides a way to reconstruct executed file commands.

Seis variedades de milho pipoca (Amarela, Roxa, Branca, Rosa-claro, Beija-flor e Viçosa), Zea mays L. (Poaceae), seus 15 híbridos F1’s e 15 híbridos F1’s recíprocos foram avaliados em um delineamento em blocos ao acaso, com três repetições, instalado em Viçosa, nos anos agrícolas 90/91 e 91/92, e Visconde do Rio Branco, em 91/92. Avaliaram-se os seguintes caracteres: altura da planta, altura da espiga, peso de grãos e capacidade de expansão. A variedade Viçosa foi indicada para ser usada em híbridos ou como fonte de linhagens para uso em programas de melhoramento intra ou interpopulacionais. O híbrido Viçosa x Roxa mostrou-se o mais desejável considerando rendimento e capacidade de expansão. As combinações Viçosa com Roxa e Rosa-claro com Beija-flor foram indicadas para iniciar programa de seleção recorrente recíproca, uma vez que foram as que mais se complementaram em relação ao peso de grãos e capacidade de expansão. Nestes programas, atenção especial deve ser dada à capacidade de expansão, que é a característica mais limitante nestes híbridos. Apesar de haver evidência de efeitos recíprocos para todos os caracteres, verificou-se pouca importância dos mesmos

O objetivo deste trabalho foi avaliar o efeito da época do anelamento do tronco na antecipação da maturação e na qualidade dos cachos de uvas finas de mesa produzidas fora de estação na região Noroeste do Estado do Paraná. O experimento foi realizado em uma parreira de videira ‘Rubi’, Vitis vinifera L. (Vitaceae) onde foram estudados os seguintes tratamentos: a. testemunha; b. anelamento 3 semanas após o pleno florescimento; c. anelamento no início do amolecimento das bagas e; d. duplo anelamento (tratamentos b e c). O anelamento consistiu na remoção da casca do tronco de aproximadamente 3-4 mm de largura, com um incisor de lâmina dupla a uma altura de 1,5 m do solo. O delineamento experimental foi o de blocos ao acaso com quatro repetições, sendo cada parcela composta por uma planta útil. Avaliou-se semanalmente, a partir da instalação do experimento, o teor de sólidos solúveis totais (SST) e acidez total titulável (ATT) das bagas até a colheita, em um total de oito amostragens. O peso e comprimento dos cachos e o tamanho das bagas também foram avaliadas por ocasião da colheita. Tanto o teor de SST como a ATT apresentaram um comportamento linear em função do tempo para todos os tratamentos e através de regressão linear foi estimado o período para que os cachos atingissem a plena maturação, considerando-se 14 oBrix como padrão. Os tratamentos b e c apresentaram os maiores períodos de antecipação da maturação de cachos em relação à testemunha (13 e 5 dias, respectivamente). Não se observaram diferenças em relação ao decréscimo do teor de ATT, tampouco em relação às características dos cachos entre os tratamentos

Uma das formas mais eficientes de aumentar a produtividade do cafeeiro nos primeiros anos da cultura é por meio de espaçamentos mais adensados. Este trabalho tem por objetivo avaliar o aproveitamento de adubo, a absorção de nutrientes e a produção de café em função de diferentes densidades de plantio. O experimento foi implantado em outubro de 1997, utilizando-se mudas de cafeeiro, Coffea arábica L. (Rubiaceae), da variedade ‘IAPAR 59’. As densidades de plantio avaliadas foram: 3.333, 5.000, 6.666, 10.000 e 20.000 plantas . ha-1. O delineamento experimental utilizado foi em blocos casualizados, com três repetições. Cada parcela experimental de 72 m2 recebeu a mesma adubação com macro e micronutrientes. Foram avaliados a produção de café beneficiado, a área foliar, a biomassa seca das folhas e os teores foliares de macro e micronutrientes e as características químicas do solo nas profundidades de 0-20 e 20-40 cm, aos 12 e 24 meses. No segundo ano de cultivo, a máxima produção por área e por planta foi alcançada com as densidades de 15.139 e 10.875 plantas há-1, respectivamente. Com 20.000 plantas, a competição entre plantas por luz, água e nutrientes é acentuada, e a produção por planta foi reduzida em 51% em relação a 10.000 plantas, entretanto, a produção por área foi semelhante entre as duas populações. Houve maior aproveitamento de N, P e K nas maiores densidades de plantio

Este trabalho teve por objetivo avaliar a influência da época de semeadura nas características agronômicas de cinco cultivares de soja, Glycine Max (L.) Merril (Leguminosae-Faboideae), na região de Maringá, Estado do Paraná. Para tanto, foram conduzidos cinco ensaios de competição de cultivares no ano agrícola 1999/00, utilizando-se delineamento experimental em blocos casualizados. Instalou-se um ensaio em cada época de semeadura (15/10, 30/10, 15/11, 30/11 e 15/12) com os cultivares BRS 132, BRS 133, BRS 134, BR 16 e FT-Estrela. Durante o desenvolvimento das plantas foram avaliadas as seguintes características agronômicas: número de dias para o florescimento e para a maturação, altura da planta, grau de acamamento das plantas e rendimento de sementes. Os resultados obtidos permitiram concluir que a época de semeadura apresentou influência sobre o número de dias para a floração e maturação, reduzindo o ciclo da cultura com o atraso na semeadura. Os menores valores de altura de plantas e grau de acamamento foram coincidentes e ocorreram para semeadura estimada em 22 de novembro. A média de rendimento dos cultivares BRS 132, BRS 133 e BRS 134 foi superior à de BR 16 e de FT- Estrela. A melhor época de semeadura para rendimento de sementes foi 15/10

O experimento foi conduzido com solo ácido da Zona da Mata do Estado de Pernambuco, submetido a diferentes níveis de calcário (0, 2, 4 e 8 t há-1), para avaliar a fixação do N2 e o desenvolvimento da soja, Glycine Max (L.) Merril, (cv. Tropical) (Leguminosae-Faboideae) com estirpes previamente selecionadas para resistência à acidez (NFB 175, de crescimento rápido, e SEMIA 542, de crescimento lento), com inoculante comercial e sem inoculação. Houve efeito na nodulação, na atividade da nitrogenase, na produção de biomassa seca e no N total da parte aérea. As estirpes NFB 175 e SEMIA 542 foram tão efetivas quanto o inoculante comercial. A adição de calcário beneficiou a fixação do N2 e o desenvolvimento da soja. Entretanto, os níveis mais elevados de calcário tiveram efeito prejudicial sobre as plantas inoculadas com as estirpes NFB 175 e SEMIA 542, indicando a necessidade de controle da calagem para a soja em solo ácido

O objetivo deste trabalho foi avaliar a eficiência na captação e no aproveitamento da água, pelas culturas da soja, Glycine Max (L.) Merril, e do feijão, Phaseolus vulgaris L. e também pelas espécies de plantas daninhas Euphorbia heterophylla (resistente e suscetível a herbicidas inibidores da enzima ALS), Bidens pilosa e Desmodium tortuosum, bem como avaliar o direcionamento de seus fotoassimilados e a duração de seus ciclos. Nenhuma das espécies daninhas avaliadas, completaram o ciclo antes da colheita do feijão, que foi a planta a utilizar mais eficientemente a água fornecida no início do ciclo. Na fase vegetativa, B. pilosa foi a espécie que mais drenou seus fotoassimilados na formação de raízes. Soja foi a planta que apresentou a maior taxa de acúmulo de biomassa diária e maior eficiência no uso da água, durante todo o ciclo. Entre as plantas daninhas, D. tortuosum foi a mais eficiente na captação e aproveitamento da água na fase vegetativa e B. pilosa após o florescimento. Os biótipos de E. heterophylla apresentaram equivalência competitiva

Um ensaio de competição de linhagens de café (Coffea arábica L. “Catimor”) (Rubiaceae) foi conduzido com o objetivo de estimar as correlações genotípicas e as relações causa-efeito entre a produtividade de café beneficiado e outras características agronômicas. A produtividade de café beneficiado apresentou as maiores correlações com vigor vegetativo, seca de ponteiros e época de maturação. Pela análise de trilha, verificou-se que o maior efeito direto sobre a produtividade de café beneficiado foi do vigor vegetativo, com quem também apresentou a maior correlação. Houve efeito direto de seca de ponteiros sobre produtividade de café beneficiado. Apesar da alta correlação genotípica detectada entre produtividade de café beneficiado e época de maturação, estas não apresentaram relação causa-efeito. A produtividade também não foi influenciada por diâmetro da copa, altura da planta ou curvatura dos ramos

O experimento foi conduzido na ESALQ/USP, em Piracicaba, Estado de São Paulo, com o objetivo de estudar o efeito do aumento da concentração de CO2 e do volume de água aplicados em plantas de pimentão, Capsicum annum L. (Solanaceae), cultivadas em vasos, em ambiente protegido. O CO2 foi aplicado diariamente, através de microtubos instalados a 3m de altura, sobre a linha de plantas. Utilizou-se o sistema de irrigação por gotejamento com um gotejador por planta e freqüência de dois dias. Adotaram-se quatro concentrações de CO2 (367, 600, 800 e 1000µmol.mol-1) e quatro volumes de água, definidos pelo volume de água evapotranspirado (30,89L, 40,7L, 61,86L e 82,83L), com quatro repetições. Foram avaliadas as características altura das plantas, diâmetro do caule e área foliar. Verificou-se que o aumento do volume de água promoveu acréscimo na altura, diâmetro e área foliar. Nos ambientes enriquecidos com CO2 a área foliar foi menor e o crescimento vegetativo na fase inicial foi mais uniforme
Mapeamento do comprimento de rampa em microbacias com Sistema de Informação Geográfica
Authors: Valeriano Marcio De Morisson
Published: June 2016

São apresentados procedimentos para a geração de imagens de comprimento de rampa em microbacias por Sistemas de Informação Geográfica (SIG). Os métodos de geoprocessamento foram avaliados com análises de regressão entre os resultados digitais e um conjunto de dados cartográficos medidos manualmente numa grade regular de 200 m de espaçamento, sobre toda a área da microbacia do córrego São Joaquim (Pirassununga, Estado de São Paulo). A função de análise de custos anisotrópicos do SIG foi adaptada para modelar o comprimento de rampa, explorando-se a semelhança dos conceitos e a analogia entre seus elementos e feições topográficas. Os passos de extração desses elementos do Modelo Digital de Elevação (DEM), divisores, direção de rampa, força de rampa e distância unitária, assim como todos os procedimentos desenvolvidos, foram programados em um arquivo de linguagem específica do SIG usado. A ocorrência de erros nas determinações de comprimento de rampa prevaleceu em áreas de relevo acidentado com declividades altas e rampas curtas, o que indica a necessidade de se estabelecerem procedimentos mais sofisticados de ajuste para os resultados de SIG

A deficiência hídrica tem sido um dos principais fatores responsáveis pela baixa produtividade e qualidade de sementes de arroz de terras altas, impulsionando o cultivo no sistema irrigado por aspersão. Dessa forma, foram conduzidos experimentos nas safras 1994/95 e 1995/96 em áreas pertencentes à Faculdade de Engenharia da Universidade Estadual Paulista - Unesp, Campus de Ilha Solteira, Selvíria - Estado do Mato Grosso do Sul, com o objetivo de avaliar a produtividade e a qualidade fisiológica de sementes de arroz, Oryza sativa L. (Poaceae), de duas cultivares, Carajás e IAC 201, sob dois sistemas de cultivo, sequeiro e irrigado. Foram determinados a produtividade, a massa de mil sementes e a qualidade fisiológica das sementes. O sistema irrigado por aspersão mostrou-se superior ao de sequeiro em todas as determinações realizadas nos dois anos de experimentação. A cultivar Carajás, independente do ano e sistema de cultivo, apresentou melhor desempenho em relação a IAC 201
