Towards Modern Cost-effective and Lightweight Augmented Reality Setups
Authors: Pádua Luís , Adão Telmo , Narciso David , Cunha António , Magalhães Luís , Peres Emanuel
Published: August 2016

Augmented Reality (AR) has been widely used in areas such as medicine, education, entertainment and cultural heritage to enhance activities that include (but are not limited to) teaching, training and amusement, through the completion of the real world with viewable and usually interactive virtual data (e.g. 3D models, geo-markers and labels). Despite the already confirmed AR benefits in the referred areas, many of the existing AR systems rely on heavy and obsolete hardware bundles composed of several devices and numerous cables that usually culminate in considerably expensive solutions. This issue is about to be tackled through the recent technological developments which currently enable the production of small-sized boards with remarkable capabilities – such as processing, visualization and storage – at relatively low prices. Following this line of reasoning, this paper proposes and compares five different multi-purpose AR mobile units, running Windows or Android operating systems, having in mind low-cost and lightweight requirements and different levels of immersion: a laptop computer, two tablets, a smartphone and smartglasses. A set of tests was carried out to evaluate the proposed unit performance. Moreover, a set of users' assessments was also conducted, highlighting an overall acceptance regarding the use of the proposed units in AR applications. This paper is an extension of a previous work (Pádua et al., 2015) in which a conceptual architecture for mobile units - complying with AR requirements (including visualization, processing, location and communication) for indoor or outdoor utilization - was presented, along with a shorter set of lightweight and cost-effective AR mobile units and respective performance tests.
Factors in the Choice of MIS as a Major
Authors: Rouibah Kamel
Published: August 2016

Decline of student enrollment in MIS major is still an issue. In order to reverse the trend, this study highlights the drivers toward the management information system (MIS) major in an Arab country based on the Theory of Reasoned Action (TRA) and the Network Externalities Theory. This is the first study that integrates the perceived number of enrolled students (PNES) with TRA in addition to other variables (reputation of the instructor, job availability, financial considerations, computer self-efficacy, easiness of the major, and IT anxiety) with intention to enroll in MIS. The model was tested with 499 undergraduate students and analyzed with LISREL. Results indicate that, unlike western culture, the subjective norms and PNES (and not attitude) are important drivers toward the major. This study is relevant for practitioners who can learn strategies to attract more students to the MIS major.

Authors: Lv Peng Fei , Wang Xia , Zou Hua
Published: August 2016

In this work, poly(2-aminothiazole) (P2AT) was synthesized by chemical oxidation method using 2-aminothiazole as the monomer. The polymerization was initiated using three different oxidants, CuCl2, FeCl3 and (NH4)2S2O8. The results suggested that the monomer was easily polymerized and higher yields were achieved when CuCl2 was used as the oxidant. The effects of reaction time and polymerization temperature on the yield of polymerization using CuCl2 were investigated. The polymerization yield of the P2ATs was 25.2 % at oxidant/monomer molar ratio of 0.1 for 24 h in the copper chloride /deionized water. The P2ATs were characterized by FT-IR, UV-vis, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM).

Authors: Zhao Shi Ran , Zhang Kai Feng , Meng Gang , Yao Yuan , Wang Ning , Geng Fei , Li Wen Long
Published: August 2016

In this paper, the performance of steel slag composite cementitious material and the performance of steel slag concrete were studied, which provides reference for the comprehensive utilization of steel slag. The test shows that the activity of steel slag composite cementitious material with the specific surface area is greater than or equal to 400m2/kg to meet the use requirements; When the maximum content of coarse aggregate of steel slag was 25%, the volume stability of steel slag concrete was best. But when the content of steel slag powder was controlled within 30%, the concrete had good resistance to carbonation.

Published: August 2016

Martensitic high-carbon, high-strength bearing steel is used for rolling contact applications when high wear and fatigue resistance are required. Due to its high fatigue strength, SUJ2 is not used for only bearings but for shafts. The objective of this work is a clarification of the relationship between quenching times and retained austenite amount of SUJ2 steel. It was found that repeatedly induction heating increased the retained austenite amount, but did not change the Vickers hardness.

Authors: Demeekul Nantawat , Sikong Lek , Masniyom Manoon
Published: August 2016

This study aims to investigate the effect of flotation operating parameters such as immersion depth of downcomer and air flow rate on performance of barite minerals separation. The barite minerals utilized in this experiment mainly consist of barite and gangue minerals such as quartz, kaolinite, illite and microcline having the chemical compositions of 63.12% BaSO4, 18.22% SiO2, 13.49%Al2O3, 1.02% K2O, 0.69% Fe2O3 and 3.46% others and the particle size (d80) of about 37 microns. In the flotation cell, the air bubbles were generated using designed porous materials. The flotation of barite minerals were carried out in an alkaline condition at pH 9 with sodium oleate collector and terpineol frother. It was found that concentrate grades of barite for the air flow rates of 20, 30 and 40 L/min were nearly constant about 70% BaSO4 at the immersion depths of 5 and 10 cm but it increased at the depth of 15 cm. The immersion depth of 5 and 10 cm seems to have no effect on grade of concentrate while the depth of 15 to have such effect. The air flow rate had an effect on concentrate grade when 15 cm immersion depth was used. The optimum air flow rate of 30 L/min gave concentrate grade of 85% BaSO4 with the recovery and enrichment ratio of 73% and 1.3, respectively.
Synthesis of Thermochromic Mo-Doped VO2 Particles
Authors: Phoempoon Phatcharee , Sikong Lek
Published: August 2016

Mo-doped vanadium dioxide particles were produced by simple solution-based, rapid microwave assisted, and calcination in an inert gas method respectively. The precursors and the heat-treated final powders were characterized by X-ray diffractometer (XRD), differential scanning calorimeter (DSC), scanning electron microscope (SEM), and transmission electron microscope (TEM). The Mo dopant influenced the crystal structure and phase transition of VO2 (M) particles. The XRD pattern indicated that all Mo-doped VO2 particles were monoclinic crystal. The DSC results showed that phase transformation temperature of VO2 from monoclinic to tetragonal or rutile, which normally occurred at 67-68 oC was reduced to 43.18 oC, whereas over doping of Mo led to the increased transition temperature. The results suggested a significant effect of Mo doping content on the transition temperature of VO2. Doping with an optimum amount of Mo into VO2 structure can achieve the lowest phase transformation temperature of VO2 powders.

Published: August 2016

In the present research, a kind of special emulsions explosive was prepared with taking Ferric nitrate and Manganese nitrate as main oxidants and composite oil as fuel, in which the Magnesium and zinc elements were added and doped in Mn ferrites. The results of which were compared by that of detonation of gas (Hydrogen and oxygen). Results indicated that the detonation products were the same structure, i.e. Jacobsite structure. That is to say, Magnesium and zinc elements were successfully doped in MnFe2O4 crystals. TEM indicated that the powders were spherical and average size was about 20~30nm. The product that obtained by gas detonation was better dispersed and worse uniform than that by explosive. Zn and high content Mg both had great effect on the stability and detonation properties of the explosive, which could produce impurities in detonation products.

Best practices from changing diabetes® in children India
Authors: Prasanna Kumar K. , Shah Nalini , Viswanathan Vijay , Sarda Archana , Chugh Shuchy , Dinakaran P.
Published: August 2016

It is estimated that India alone has 70,200 cases of T1DM, with an annual increase rate of 3–5%.2 Despite being the most common chronic disease in children and adolescents, T1DM does not receive the attention it requires. Many children die of undiagnosed diabetes or shortly after diagnosis because of poor blood sugar control. Everyone with type 1 diabetes requires insulin from the beginning.3 Continuous management, comorbidities, and chronic complications place a heavy psychological and economic burden on the whole family. Challenges in India are at many levels, right from diagnosis, health-care delivery, availability of trained physicians, infrastructure, insulin, and monitoring and providing psychosocial support. The Changing Diabetes® in Children (CDIC) Programme is a part of Novo Nordisk's Access to Diabetes Care strategy and builds on the undefined cornerstones in the right to health. With an aim to improve the health condition and quality of life of the children with diabetes, this program was started in 2009. Globally, the program is operational in nine underdeveloped and developing countries including India and there are a total of >14,000 children under the care of the CDiC Programme. This global program was launched in India in 2011 by late former President Dr. APJ Abdul Kalam through Novo Nordisk Education Foundation. It has a pan-India footprint with 21 established centers in government hospitals and specialized clinics and >4000 registered children. Apart from providing essential care which includes free doctor consultations, providing insulin, and monitoring insulin, CDiC is also working in other key areas in type 1 management, namely, (1) diabetes education–with specially designed diabetes education tools, for children, parents, siblings, and other caregivers, (2) awareness and capacity building–advertorial series for general public and special accredited trainings for doctors and other health-care professionals, and (3) communication for all stakeholders–periodic CDiC newsletters and Mishti Guardian.

Portable microscopy may facilitate quality diagnostic care in resource-constrained settings. We compared a handheld light microscope (Newton Nm1) with a mobile phone attachment to conventional light microscopy for the detection of Plasmodium falciparum in a cross-sectional study in rural Côte d'Ivoire. Single Giemsa-stained thick blood film from 223 individuals were prepared and read by local laboratory technicians on both microscopes under 1,000× magnification with oil. Of the 223 samples, 162 (72.6%) were P. falciparum positive, and the overall mean parasite count was 1,392/μL of blood. Sensitivity and specificity of the handheld microscope was 80.2% (95% confidence interval [CI]: 73.1–85.9%) and 100.0% (95% CI: 92.6–100.0%), respectively, with a positive and negative predictive value of 100.0% (95% CI: 96.4–100.0%) and 65.6% (95% CI: 54.9–74.9%), respectively. If sensitivity can be improved, handheld light microscopy may become a valuable public health tool for P. falciparum diagnosis.
Female infanticide and female-directed lethal targeted aggression in a group of ring-tailed lemurs (Lemur catta)
Authors: Kittler Klara , Dietzel Silvio
Published: August 2016

Abstract. We report on extremely rare events of lethal aggression in a semi-captive group of ring-tailed lemurs (Lemur catta) during the birth season 2014. This aggression was targeted against the two highest-ranking females. It led to their eviction from the group and following a final aggressive interaction four days later to their deaths caused by almost all the females and probably even two males of their former group. These events of targeted aggression erupted initially following an infanticide by the highest-ranking female directed at the offspring of a subordinate. Even for ring-tailed lemurs this is a very special case of changeover of power between two different matrilines in a group. In accordance with other studies we suggest that these events of targeted aggression were based on the growing group size and were acts of female reproductive competition during birth season. With the intensity of the events we add new aspects to the existing knowledge of aggressive interactions in ring-tailed lemurs.

Published: August 2016

The construction of one or more plants in optimum sites and in the best possible situation, not only improves materials circulation and customer services, but also puts the company in a desirable situation. Decisions associated with the selection and acquisition of features of a center’s site selection can have a great impact on the ability to gain and maintain competitive advantages. This study tests the impact of distance from population centers on the profitability for the first time. The sample which has been used in the food products industry, includes 21 firms listed in Tehran Stock Exchange during 2009 to 2014, and panel data regression methods were used to process and test the hypotheses. The results showed that product market competition enhances the negative impact of corporate distance from Tehran and big cities on the basic earnings power (earnings before tax). However, the relative power of the firm in a competitive environment weakens the negative impact of corporate distance from Tehran and big cities on the basic earnings power (earnings before tax).
Mahmood, Liberalism, and Agency
Authors: Ranganathan Bharat
Published: August 2016

In her book, Politics of Piety, Saba Mahmood (1) challenges liberal views about agency, and (2) offers her own account of agency. This article argues that Mahmood's characterization of liberal agency is a caricature. Contrary to her view, liberalism isn't merely procedural but rather espouses stringent commitments toward protecting people's basic rights and liberties. This article then argues that her account of agency may entail practices decried by liberal and some feminist theorists. Specifically, practices that override one's status in moral and political communities cannot be defended on the grounds that they are necessary for particular forms of human flourishing.
Campaign Finance and Collective Egotism: What Niebuhr Offers a Stultified Debate
Authors: Kelly Conor M.
Published: August 2016

Currently, campaign finance law in the United States is governed by the Supreme Court's 2010 decision in Citizens United v. FEC, but the debate surrounding the case has grown tired. In order to reinvigorate public discourse on this consequential topic, this article proposes an interdisciplinary conversation between theology and law, relying on Reinhold Niebuhr's notion of collective egotism to shed new light on the decision. The comparison with Niebuhr highlights the Court's problematic reliance on unexamined empirical claims, pinpointing areas of the case in need of further critical assessment and suggesting viable alternatives. The result is a more precise diagnosis of the problems in contemporary campaign finance law and a more practical way forward for the public debate.

Envelhecer no mundo contemporâneo: oportunidades e incertezas
Authors: Amaro Fausto
Published: August 2016

O envelhecimento pode ser analisado pelo prisma do aumento demográfico, como por exemplo, quando se projeta que em 2050 a população idosa será de cerca de 2 bilhões de indivíduos. Este número traduz a profunda alteração demográfica que se registra em todas as regiões do planeta. Entretanto, a população mais idosa se concentra atualmente nas zonas mais desenvolvidas, sendo os países europeus os que se encontram no grupo dos mais envelhecidos. As causas diretas desta evolução demográfica se vinculam à melhoria das condições de vida e ao progresso da medicina. Mas viver mais anos não parece ser suficiente para aumentar o bem-estar e a felicidade humana. Viver mais anos só faz sentido se o aumento de longevidade for acompanhado de qualidade de vida. Um dos aspectos que influencia a longevidade são as atitudes das pessoas, que podem ser definidas como estados internos que predispõem para reações positivas ou negativas a respeito das coisas, dos outros e de si próprio. As atitudes negativas constituem uma importante barreira à qualidade de vida, podendo igualmente contribuir para estados depressivos. As atitudes positivas influem bastante na qualidade de vida e na própria longevidade.

Published: August 2016

Introduction: We sought to evaluate the accuracy of prostate volume estimates in patients who received both a preoperative transrectal ultrasound (TRUS) and magnetic resonance imaging (MRI) in relation to the referent pathological specimen post-radical prostatectomy.

Methods: Patients receiving both TRUS and MRI prior to radical prostatectomy at one academic institution were retrospectively analyzed. TRUS and MRI volumes were estimated using the prolate ellipsoid formula. TRUS volumes were collected from sonography reports. MRI volumes were estimated by two blinded raters and the mean of the two was used for analyses. Pathological volume was calculated using a standard fluid displacement method.

Results: Three hundred and eighteen (318) patients were included in the analysis. MRI was slightly more accurate than TRUS based on interclass correlation (0.83 vs. 0.74) and absolute risk bias (higher proportion of estimates within 5, 10, and 20 cc of pathological volume). For TRUS, 87 of 298 (29.2%) prostates without median lobes differed by >10 cc of specimen volume and 22 of 298 (7.4%) differed by >20 cc. For MRI, 68 of 298 (22.8%) prostates without median lobes differed by >10 cc of specimen volume, while only 4 of 298 (1.3%) differed by >20 cc.

Conclusions: MRI and TRUS prostate volume estimates are consistent with pathological volumes along the prostate size spectrum. MRI demonstrated better correlation with prostatectomy specimen volume in most patients and may be better suited in cases where TRUS and MRI estimates are disparate. Validation of these findings with prospective, standardized ultrasound techniques would be helpful.
Anticholinergics for overactive bladder: Temporal trends in prescription and treatment persistence
Authors: Wallis Christopher J.D. , Lundeen Colin , Golda Nicole , Brotherhood Hilary , Pommerville Peter , Carr Lesley
Published: August 2016

Introduction: We sought to understand the contemporary pharmacologic management of overactive bladder (OAB) in a single-payer system. We examined temporal trends in the use of anticholinergic
medications and assessed whether the likelihood of patients changing their anticholinergic therapy was predicted by their current therapy.

Methods: We conducted a retrospective, population-based analysis of prescription records from the PharmaNet database in BC, Canada. We identified patients treated with one or more anticholinergic
prescriptions between 2001 and 2009. We characterized temporal trends in the use of anticholinergic medications. We used generalized estimating equations with a logit wing to assess the relationship between the type of anticholinergic medication and the change in prescription.

Results: The 114 325 included patients filled 1 140 296 anticholinergic prescriptions. The number of prescriptions each year increased over the study, both in aggregate and for each individual medication. While oxybutynin was the most commonly prescribed medication (68% of all prescriptions), the proportion of newer anticholinergics (solifenacin, darifenacin, and trospium) prescribed increased over time (p<0.0001). Patients taking tolterodine (odds ratio [OR] 1.03; p=0.01) and darifenacin (OR 1.12; p=0.0006) were significantly more likely to change their prescription than those taking oxybutynin. There was no association seen for patients taking solifenacin (p=0.6) and trospium (p=0.9).

Conclusions: There are an increasing number of anticholinergic prescriptions being filled annually. Patients taking newer anticholinergics are at least as likely to change therapy as those taking
oxybutynin. The reimbursement environment in BC likely affects these results. Restrictions in the available data limit assessment of other relevant predictors.

Published: August 2016

Introduction: Our aim was to assess adherence to National Comprehensive Cancer Network (NCCN) and American Urological Association (AUA) guidelines for pelvic lymph node dissection (PLND) at the time of either robot-assisted (RARP) or open radical prostatectomy (ORP).

Methods: We relied on the Surveillance, Epidemiology, and End Results-Medicare linked database and focused on localized prostate cancer (PCa) patients who were treated with either RARP or ORP between October 2008 and December 2009. Categorical and multivariable logistic regression analyses targeted two endpoints: 1) probability of guideline-recommended PLND; and 2) probability of no PLND, when not guideline-recommended.

Results: Among 5268 PCa patients, adherence to NCCN PLND guideline was 56.9% during RARP and 76.5% during ORP (odds ratio [OR] 0.4, 95% confidence interval [CI] 0.3‒0.6). AUA PLND guideline adherence was 68.1% during RARP and 82.4% during ORP (OR 0.7, 95% CI 0.5‒0.9). When PLND was not recommended, it was more frequently performed during ORP according to either NCCN (OR 3.7, 95% CI 3.5‒3.9) or AUA (OR 2.7, 95% CI 2.6‒2.8). According to the NCCN guideline, at recommended PLND in ORP patients, 6.3% harboured lymph node invasion (LNI) (number needed to treat [NNT] 16) vs. 3.2% at RARP (NNT 31). According to the AUA guideline, at recommended PLND in ORP patients, 12.3% harboured LNI (NNT 8) vs. 5.1% RARP (NNT 19).

Conclusions: Adherence to NCCN and AUA PLND guidelines was lower during RARP than during ORP when PLND was recommended. The rate of non-recommended PLND was also higher during ORP than during RARP. Technical considerations may be at play.
A prospective evaluation of obesometric parameters associated with renal stone recurrence
Authors: Bos Derek , Dason Shawn , Matsumoto Edward , Pinthus Jehonathan , Allard Christopher
Published: August 2016

Introduction: Our aim was to evaluate whether obesometric serum hormones and body fat distribution are associated with renal stone recurrence.

Methods: We conducted a prospective cohort study of participants undergoing renal stone (RS) intervention at a single institution from November 2009‒June 2010 and followed them for a median 62 months. Obesometric parameters were measured at baseline, including body mass index (BMI), fasting serum leptin and adiponectin, and proportion of visceral adipose tissue (%VAT) averaged from three fixed axial computed tomography (CT) slices. The primary study outcome was stone recurrence.

Results: A total of 110 participants were enrolled. Elevated %VAT was associated RS recurrence; participants with %VAT in the highest quartile had a five-year stone-free rate of 47.1% compared to 72.2% among other participants (p=0.004). Adjusting for gender, elevated %VAT was independently predictive of renal stone recurrence among initial stone formers (n=74; hazard ratio [HR] 4.53, 95% confidence interval [CI] 1.08‒19.02), but not among recurrent stone formers (n=19; HR 0.51, 95% CI 0.054‒4.72). Other obesometric factors, including leptin, adiponectin, and BMI, were not significantly predictive of recurrence.

Conclusions: We report a novel association between an elevated %VAT and stone recurrence. These findings may inform patient counselling and followup regimens. The metabolic basis for these findings requires further investigation.

Published: August 2016

Performance appraisal is credited by researchers as a tool for spurring employees towards the attainment of organizational goals. Considering employees’ attitudes as a vital component in the attainment of organizational goals, this study investigated the impacts of performance appraisal on the job-satisfaction and commitment of employees. The study used a descriptive research design. A stratified random sampling was used to sample 200 respondents from Microfinance organizations in Ghana. The study used questionnaires as its data collection instrument. Regression Analysis and correlations were used to analyze the data collected. The study revealed that employees’ job satisfaction is positively related to and impacted by fairness in the appraisal system, linking appraisals with promotion, clarity of roles and feedback about their performance. The study also revealed that employees’ commitment is positively related to and impacted by the linkage of appraisals with salary, identification of training needs, clarity of performance appraisal purpose and employee involvement in the formulation of appraisal tools.

O presente estudo foi baseado na utilização da teoria dos modelos não-lineares de efeito misto em multiníveis para a modelagem do crescimento em altura de povoamentos clonais de Eucalyptus. A base de dados utilizada representa medições de árvores individuais, tomadas em diferentes locais e no tempo, sendo a mesma classificada de longidudinal, irregularmente espaçada, não-balanceada, com autocorrelação e com a presença de heterogeneidade de variância. O modelo logístico de três parâmetros foi utilizado para a estimativa do crescimento em altura. Os parâmetros do modelo foram estimados como de efeitos fixos e aleatórios em dois níveis: unidade amostral (nível 1) e árvore individual dentro das unidades amostrais (nível 2). A inclusão de tais níveis reduziu sensivelmente o erro padrão da estimativa para o modelo. As estimativas também foram melhoradas com a modelagem da heterogeneidade da variância, utilizando estruturas diagonais, e da autocorrelação, com a estrutura ARMA(2,1).

O presente trabalho integra o conjunto de estudos e pesquisas previstas no Projeto Ecológico de Longa Duração - PELD/CNPq, instalado FLONA de São Francisco de Paula, RS. Teve como objetivo identificar e caracterizar os diferentes estágios sucessionais de remanescentes de Floresta Ombrófila Mista. O trabalho foi realizado em dez conglomerados permanentes de 100m x 100m (10.000m2), os quais foram divididos em dez faixas de 10m x 100m (1.000m2) e estas subdivididas em dez subunidades de 10m x 10m (100m2). Para a presente pesquisa, foi sorteada uma faixa de 10m x 100m para cada conglomerado, totalizando cem subunidades amostrais (parcelas) onde foram instaladas, na altura do DAP, bandas (cintas) dendrométricas em todas as árvores com CAP > 30cm, para medição anual dos diâmetros. A análise de agrupamento foi realizada por meio do programa Twinspan, utilizando uma matriz de dados com 99 parcelas (uma foi desconsiderada por não apresentar indivíduos com CAP > 30cm) tendo como variável o incremento anual em diâmetro (obtido de 2 anos de observação) de 69 espécies. Obtiveram-se três grupos florísticos que indicaram estágios sucessionais na floresta: um grupo separou um estágio sucessional menos evoluído denominado de mata secundária, tendo Nectandra megapotamica e Cryptocarya aschersoniana como espécies indicadoras; um segundo grupo indicando um estágio sucessional intermediário da floresta, com Sebastiania commersoniana e Ocotea pulchella como espécies indicadoras; e um terceiro grupo constituído da floresta primária cuja espécie indicadora foi Araucaria angustifolia.

Várias espécies da família Lauraceae estão entre as mais comuns na Floresta de Araucária. Elas possuem bom potencial silvicultural e econômico, mas são pouco estudadas. Este trabalho trata das mudanças estruturais no período 1995-2004 de oito espécies da família Lauraceae ocorrentes em um fragmento florestal localizado no centro-sul do estado do Paraná. As espécies foram analisadas pelos indicadores estruturais e dinâmicos: IVI, abundância, área basal, volume, distribuição diamétrica, distribuição espacial, recrutamento, mortalidade e incrementos. Os resultados demonstraram que, em 10 anos de dinâmica estrutural, a família Lauraceae, de maneira geral, manteve inalterada sua posição de importância na comunidade. Observou-se que as Lauráceas passam por aumento de densidade, porque o recrutamento está sendo maior que a mortalidade. Já o crescimento das Lauráceas tem sido muito baixo, tanto em diâmetro como em área basal e volume. Embora a maior parte das Lauráceas apresente um padrão dinâmico lento, algumas espécies passam por um intenso processo de mudanças, como é o caso da canela-amarela (Nectandra grandiflora Nees & Mart. ex Nees), que aumentou a maioria dos seus indicadores estruturais e dinâmicos, constituindo-se na espécie de maior destaque entre as analisadas. Essa espécie apresenta recrutamento muito superior à mortalidade, distribuição diamétrica decrescente e ampla distribuição espacial. Esses elementos estão tornando essa espécie em uma das três mais importantes em toda a comunidade, juntamente com a araucária (Araucaria angustifolia (Bertol.) Kuntze) e a erva-mate (Ilex paraguariensis A.St.-Hil.). Concluiu-se que, em 10 anos, já é possível distinguir processos ecológicos importantes que podem servir como indicativos em Planos de Manejo para Florestas semelhantes de Araucária.

Published: August 2016

Heredabilidad en sentido estricto (h2), correlación genética intra-clase (Γ2IC) y componentes de varianza para la altura, diámetro a la altura del pecho (DAP) y volumen del fuste, a los siete años de edad después de la plantación, fueron analizados en dos ensayos de progenie de Pinus radiata establecidos en el sur de Chile, en orden a examinar la variabilidad genética del crecimiento en una generación avanzada de la especie. Estos ensayos incluyeron árboles provenientes de propagación vegetativa y generativa. Las heredabilidades fueron estimadas para los árboles originados de semillas, y mostraron los siguientes valores: altura, 0.08-0.13; diámetro a la altura del pecho, 0-0.13; volumen del fuste, 0-0.09. Los valores de la correlación genética intra-clase, estimados para el grupo de árboles originados de propagación vegetativa, fueron moderados a bajos (Γ2IC: altura, 0.1-0.11; diámetro a la altura del pecho, 0.01-0.05; volumen del fuste, 0.03-0.06). No obstante la presencia de heredabilidades y correlaciones moderadas para algunas características y, la variación relativamente limitada entre grupos de árboles reflejan la fuerte selección realizada a las progenies. En general, los árboles provenientes de estacas presentaron una tendencia a la menor variación intra-genotípica, y evidenciaron magnitudes relativas de las varianzas debida al grupo (σ2G) mayores a las varianzas familiares (σ2F), en cuatro de seis caracteres evaluados, indicando una tendencia a la mayor homogeneidad en el crecimiento, característica común de la propagación vegetativa.

Este trabalho teve o objetivo de avaliar a reação de resistência a pragas e doenças de clones locais do vimeiro comum, Salix x rubens, e de espécies introduzidas da Argentina, Chile, Alemanha e França. Três experimentos foram conduzidos em campo no ciclo de cultivo 2003/2004, em diferentes ecossistemas do Planalto Serrano Catarinense. As avaliações de resistência constaram da estimativa de danos causados pelos insetos e da severidade de doenças foliares. No conjunto de todas as avaliações, os acessos - genótipos introduzidos - EEL_10 (Salix nigra), EEL_08 (Salix sp.), EEL_02 (Salix x rubens), EEL_13 (Salix sp.), EEL_09 (Salix alba), e EEL_20 (Salix sp.) foram os mais resistentes ao ataque de pragas e doenças. Dada a reação diferenciada dos acessos quanto ao ataque de doenças e pragas, as próximas ações de pesquisa devem proceder aos testes de artesanato para verificar a sua adequação à demanda para confecção de peças finas.

Neste estudo, foram analisados os principais componentes químicos da madeira da Moquinia polymorpha (LESS.) DC., conhecida como candeia ou cambará, nativa da região Sul de Minas Gerais. A composição química dessa madeira foi: 47,5% de α-celulose, 25,4% de hemiceluloses A e B, 24,0% de lignina, 73,2% de holocelulose, 3,82% de extrativos em etanol:cicloexano (1:1, v v-1), 3,21% em etanol e 4,04% em água quente. Nos compostos voláteis identificados, destacaram-se: α-curcumeno, α-diidroturmerona, β-diidroturmerona, cedranol, 1-ciclopentil-3-[2,4-dimetil-fenil]propano. A análise dos fenóis totais foi conduzida com base nos extratos metanol-água (MA) e acetona-água (AA), em que esse último apresentou maior rendimento. O teor de fenóis totais foi determinado pelos métodos Folin-Ciocalteau e Azul da Prússia modificado. No método Folin-Ciocalteau, foram encontrados 0,93 mg g-1 de madeira para o extrato MA e 1,56 para o extrato AA e no método azul da Prússia modificado, foram determinados 2,74 mg g-1 de madeira para o extrato MA e 4,42 para o extrato AA. O teor de proantocianidinas foi determinado pelos métodos da vanilina e n-butanol:ácido. No método n-butanol:ácido, foram encontrados 0,012 mg g-1 de madeira para o extrato MA e 0,017 para o extrato AA e, no método da vanilina, foram determinados 0,29 mg g-1 de madeira para o extrato MA e 0,58 para o extrato AA. Não foram detectados 3-deoxi-proantocianidinas.

A silvicultura de precisão visa aumentar a eficiência da produção agrícola, fundamentada em manejo diferenciado de áreas de agricultura. O objetivo deste trabalho foi analisar e comparar o desenvolvimento do ipê roxo (Tabebuia avellanedae Lorentz ex Griseb.) sob duas formas de manejo de solo. A análise foi realizada durante o período de 01/03/03 a 01/03/04 em uma área no município de Mundo Novo-MS, dividida em dois blocos, e cada bloco em duas parcelas: uma sob manejo de silvicultura de precisão e outra sob manejo convencional. Cada uma das parcelas recebeu 252 mudas de ipê-roxo, totalizando 1008 plantas. Utilizaram-se técnicas geoestatísticas como semivariogramas para análise da estrutura da variabilidade espacial dos dados e a interpolação por krigagem para a construção de mapas temáticos. Dos resultados obtidos, tem-se que os mapas de necessidade e aplicação de nutrientes e os mapas de incremento na altura das plantas apresentaram estrutura de variabilidade semelhante para ambos os manejos. Nenhuma diferença expressiva entre os tratamentos foi encontrada.

Com o objetivo de avaliar a viabilidade de uso da técnica ultra-sônica para estimar o teor de umidade da madeira durante o processo de secagem, amostras de Pinus elliottii Engelm. e Eucalyptus grandis W. Hill ex Maiden, com dimensões nominais 3,5 x 10 x 25 cm de espessura, largura e comprimento, respectivamente, foram submetidas às temperaturas de 20, 40 e 70ºC. Um equipamento ultra-sônico PUNDIT com transdutores de faces planas de 50 kHz foi utilizado para medir a velocidade de propagação do som na direção longitudinal da madeira. Os resultados indicaram aumento da velocidade ultra-sônica estimada em função da redução do teor de umidade. Essa relação mostrou-se válida no intervalo desde verde até o final da secagem, sendo que os melhores coeficientes de determinação ocorreram na madeira de eucalipto (R² = 81%). Embora não tenha sido observada uma influência da espécie na velocidade ultra-sônica, esta foi influenciada pela massa específica da madeira e pela temperatura de secagem. O efeito da massa específica foi diretamente proporcional para a madeira de pinus e inversamente proporcional para a madeira de eucalipto. A velocidade ultra-sônica apresentou tendência de redução com o aumento da temperatura de secagem para ambas as espécies, e os resultados obtidos sugerem que o método ultra-sônico apresenta bom potencial para o controle do processo de secagem.
