Natural durability of four Tunisian Eucalyptus spp. and their respective compositions in extractives

Abstract Eucalyptus trees have been adapted to the Tunisian climate. Now, they need to be economically valued. Tunisian Eucalyptus have great technological properties allowing us to use them as wooden material. However, there is large variability in the natural durability between heartwood Eucalyptus spp. The wood sustainability assessment provides reliable parameters to predict the service life of wood-based products. This study aimed to evaluate the wood deterioration of four North Tunisian fast-growing Eucalyptus spp. (Eucalyptus maidenii, Eucalyptus saligna, Eucalyptus camaldulensis and Eucalyptus gomphocephala) exposed to basidiomycetes (Coniophora puteana and Trametes versicolor) and termite (Reticulitermes flavipes) attacks. Among the four Eucalyptus woods, Eucalyptus gomphocephala presents the highest decay and termite resistance. The four Eucalyptus wood species are classified as very durable against fungal degradation and durable against termite attacks, expect for Eucalyptus saligna which is classified as sensible against termites. The natural durability of Eucalyptus seems to be mainly caused by extractives, and a lot of compounds are involved. Antifungal and anti-termite properties of these compounds were put in perspective with the natural durability of wood. Gas chromatography-mass spectrometry (GC-MS) analyses highlighted that Eucalyptus durability is mostly governed by gallic acid, fatty acid glycerides, fatty acid esters, phenolic compounds, sitosterol, catechin and ellagic acid.
Solid Solution and Compression Behavior of Hydroxides in the Lower Mantle

The high‐pressure solid solution and compression behavior of hydroxides in the ternary MgSiO4H2‐AlOOH‐FeOOH system were studied at pressures of 16–60 GPa and temperatures of 300–1513 K. We applied in situ X‐ray measurements in conjunction with a multianvil apparatus using sintered diamond anvils to achieve homogeneous temperature distributions within large sample volumes. Our results show that CaCl2‐type hydroxides form solid solutions over a wide composition range. We also observed the volume reductions in the solid solutions accompanied by a spin transition of iron at ~50 GPa, and the wide compositional ranges are maintained through this process. Consequently, water may be transported into the deep lower mantle by the hydrous CaCl2‐type solid solution with changing its composition depending on the chemical and thermal environments.
Caracterização do perfil inflamatório e angiogênico associados ao desenvolvimento de tumores murinos

A inflamacao e a angiogenese sao caracteristicas comuns de quase, se nao de todos, os tumores solidos, no entanto nao encontramos estudos que avaliaram comparativamente estes processos em diferentes tipos de tumores visando identificar o padrao dominante em neoplasias de origens distintas. Os objetivos deste estudo foram identificar os padroes da inflamacao e angiogenese em tumores experimentais murinos de diferentes origens (melanoma, colon e mama) e caracterizar as alteracoes vasculares no tecido cutâneo adjacentes a estes tumores. Alem disso, avaliamos a contribuicao da inflamacao aguda e cronica para o desenvolvimento do tumor mamario, utilizando implantes sinteticos de polieter-poliuretano para alojar as celulas 4T1, 24h ou 10 dias pos-implantacao. A inoculacao de celulas tumorais (106) de B16F10, CT26.WT e 4T1 no flanco de camundongos resultou em massas tumorais que diferiram entre si. Melanomas (B16F10) foram duas vezes maiores do que o tumor de colon (CT26.WT) e dez vezes maiores do que o tumor mamario (4T1). Localmente, as celulas CT26.WT induziram maior numero de vasos no tecido cutâneo adjacente ao tumor, e sistemicamente, os niveis do fator de crescimento do endotelio vascular (VEGF) foram duas vezes mais altos comparados aos niveis dos dois outros tumores. A inflamacao, avaliada pela atividade das enzimas mieloperoxidase (MPO) e n-acetil--D-glicosaminidase (NAG) e pelos niveis da citocina inflamatoria, fator de necrose tumoral (TNF-) e da quimiocina CCL2 foi mais intensa no tumor mamario. O indice vascular, determinado pela quantidade de hemoglobina (Hb) e numero de vasos nas areas mais vascularizadas dos tumores, foi duas vezes maior no melanoma. A analise por citometria de fluxo da populacao celular de implantes de 24h era predominantemente de neutrofilos (42.53% +/- 8.45) e monocitos (37.53% +/- 7.48). Em implantes de 10 dias, macrofagos eram predominantes (37.10% +/- 4.54), seguidos por linfocitos (28.1% +/- 4.77) e monocitos (22.33% +/- 3.05). O tumor mamario foi duas vezes maior quando desenvolvido na inflamacao cronica comparado ao tumor desenvolvido na inflamacao aguda e cinco vezes maior comparado ao tumor desenvolvido sem o suporte inflamatorio do implante. A maioria dos parâmetros inflamatorios e angiogenicos tambem foi mais exarcebado nos tumores alojados nos implantes. Nossos resultados mostraram que tipos distintos de tumores apresentam crescimento e componentes inflamatorios e angiogenicos diferenciais quanto a intensidade dos processos. Alem disso, foi mostrado que a inflamacao cronica foi mais eficaz para o desenvolvimento do tumor mamario do que a inflamacao aguda. Este estudo contribuiu para elucidar a participacao da inflamacao e angiogenese na progressao tumoral, levantando a possibilidade de uma abordagem terapeutica para o câncer com base na intensidade destes marcadores tumorais.

Analysis of the Compliance Properties of an Industrial Robot with the Mozzi Axis Approach

In robotic processes, the compliance of the robot arm plays a very important role. In some conditions, for example, in robotic assembly, robot arm compliance can compensate for small position and orientation errors of the end-effector. In other processes, like machining, robot compliance may generate chatter vibrations with an impairment in the quality of the machined surface. In industrial robots, the compliance of the end-effector is chiefly due to joint compliances. In this paper, joint compliances of a serial six-joint industrial robot are identified with a novel modal method making use of specific modes of vibration dominated by the compliance of only one joint. Then, in order to represent the effect of the identified compliances on robot performance in an intuitive and geometric way, a novel kinematic method based on the concept of “Mozzi axis” of the end-effector is presented and discussed.
Underwater Position and Attitude Estimation Using Acoustic, Inertial, and Depth Measurements

This article considers the problem of constructing an observer for estimating position, velocity, attitude, underwater wave speed, rate sensor bias, and accelerometer bias that has both proven stability and close-to-optimal performance with respect to noise. The observer takes pseudorange, pseudorange difference, depth, and inertial measurements as input, and has a cascade structure for which the equilibrium point is proven to be locally exponentially stable due to the singularities in the attitude representation. The design of the observer is based on the exogenous Kalman filter principle, in which estimators with proven stability provide a linearization point for a linearized Kalman filter, to achieve both proven stability and close-to-optimal noise properties. Experimental validation is provided, with ground truth values generated by a camera positioning system with millimeter accuracy. The observer is compared to an extended Kalman filter and to a nonimplementable linearized Kalman filter using the true state as the linearization point, and the estimation error is almost identical to the linearized Kalman filter using the true state as a linearization point.
A High-Order Coning Error Compensation Algorithm Under High Rate Maneuvering

High-precision strapdown inertial navigation system (SINS) is of vital importance for a variety of applications. The attitude performance of SINS needs to be paid special attention especially when the platforms work under high rate maneuvering. The traditional method is based on the rotation vector algorithm by leveraging multiple samples of gyro measurements. However, the accuracy of the multiple samples algorithm is limited as the higher-order term error has not been taken into consideration. In the paper, a new high-order coning error compensation algorithm is proposed for strapdown inertial navigation system. A general algorithm for the high-order Picard component of the rotation vector differential equation is presented and a simplified correction structure of the high-order non-commutativity error is given. Simulations under coning vibrational environments showed that the proposed algorithm has higher attitude accuracy under highly dynamic vibrational conditions compared with the existing methods. Thus, the new high-order attitude updating algorithm can improve the accuracy of inertial navigation.
Infection control practices and beliefs of Minnesota dental hygienists and dental assistants.

To obtain comprehensive information about the knowledge, attitudes, and practices of Minnesota dental hygienists and registered dental assistants, a questionnaire was mailed to random samples of both groups in the fall of 1988. Most assistants and hygienists claimed to always wear gloves, but substantially fewer indicated always wearing a mask. Use of eye protection showed even lower compliance, with less than half of either group routinely using protective eyewear or a face shield. Assistants and hygienists reported incurring numerous needlesticks and instrument injuries. A contributing factor may be that many staff were still recapping needles with an unprotected hand. Most people who had not been vaccinated against hepatitis B said that they would be immunized if their employer or health insurance paid for it. Less than one-half of either group felt knowledgeable about infection control. Only one-third of assistants and less than one-half of hygienists claimed to be familiar with the Centers for Disease Control's "Recommended Infection Control Practices for Dentistry. " This is consistent with assistants' and hygienists' reported infection control related behaviors. Other than gloving, many recommended infection control measures--masking, wearing protective eyewear and uniforms, hepatitis B immunization, and proper handling of sharps--were not employed by a substantial number of respondents. Many respondents indicated insufficient knowledge to safely and effectively care for patients with hepatitis B, hepatitis B carriers, or individuals infected with the human immunodeficiency virus (HIV). This is reflected in the relatively small percentages of respondents who indicated willingness to treat these patients. (ABSTRACT TRUNCATED AT 250 WORDS)
Acute neuromuscular, cardiorespiratory and endocrine responses and chronic adaptations to combined strength and endurance training in recreationally endurance trained men and women

Taipale, Ritva Sofia Acute neuromuscular, cardiorespiratory and endocrine responses and chronic adaptations to combined strength and endurance training in recreationally endurance trained men and women Jyväskylä: University of Jyväskylä, 2013, 121 p. (Studies in Sport, Physical Education and Health, ISSN 0356-1070; 196) ISBN 978-951-39-5342-3 (nid.) ISBN 978-951-39-5343-0 (PDF) Finnish summary Diss. The aim of the present series of studies was to examine 1) chronic neuromuscular, cardiorespiratory and hormonal adaptations to prolonged periodized combined strength and endurance training using a longitudinal study design; and 2) acute neuromuscular, cardiorespiratory and hormonal responses to combined sessions using a cross-sectional study design. In the longitudinal study, following a preparatory period of strength training, recreationally endurance trained men and women were divided into specific strength training groups. Men: maximal (M), explosive (E), Men and women: mixed maximal and explosive (MM, MW) and circuit training control (CM, CW). Subjects completed an 8week strength training intervention after which M, E and CM completed 14 weeks of marathon training. Periodized maximal, explosive, and mixed maximal and explosive strength training were more effective than circuit training in improving maximal and explosive strength as well as maximal muscle activation of the lower extremities despite a progressively increasing running volume. Overall endurance performance improved (peak running speed, Speak) in all groups. After the 14-week marathon period, only M made further gains in Speak and running economy (RE). The cross-sectional study showed that when mixed strength and endurance were combined into a single session, the order of loadings, (endurance followed by strength (ES) or strength followed by endurance (SE)), led to different acute responses and recovery patterns. At recovery of 24 and 48 h, suppressed testosterone concentrations were still observed in SE men. A delayed decrease in explosive strength was observed in ES women at recovery of 24 and 48 h. Thus, the order of exercise appeared to influence the time course of neuromuscular and hormonal responses and recovery. The present results suggest that periodized maximal, explosive, and mixed strength training combined with progressive endurance training lead to improvements in neuromuscular running characteristics while the order of exercises should be considered for optimization of training.
The Role of Advanced Manufacturing Technologies in Production Process Performance: A Causal Model

Advanced manufacturing technologies (AMT) require considerable investments that managers often avoid, which makes it difficult to link their production operations with the benefits reported in literature review. The present paper shows a structural equation model that integrates four latent variables to measure the relationship between the levels of advanced manufacturing technologies implementation (Stand-Alone Intermediate and Integrated Systems), as well as the benefits obtained in the productive systems. The variables are related to each other using six hypotheses in order to realise how the AMT implementation level affects the benefits obtained from a quantitative and statistical point of view. The model is evaluated through the partial least square technique with data from 383 responses to a survey. Findings show that Stand-Alone Systems contribute more to obtaining Production Benefits, followed by Integrated Systems and Intermediate Systems. Finally, a sensitivity analysis based on conditional probabilities was performed to evaluate scenarios at different implementation levels in AMT to know how they facilitate the acquisition of the benefits offered.
Sediment Respiration Pulses in Intermittent Rivers and Ephemeral Streams

Intermittent rivers and ephemeral streams (IRES) may represent over half the global stream network, but their contribution to respiration and carbon dioxide (CO2) emissions is largely undetermined. In particular, little is known about the variability and drivers of respiration in IRES sediments upon rewetting, which could result in large pulses of CO2. We present a global study examining sediments from 200 dry IRES reaches spanning multiple biomes. Results from standardized assays show that mean respiration increased 32‐fold to 66‐fold upon sediment rewetting. Structural equation modeling indicates that this response was driven by sediment texture and organic matter quantity and quality, which, in turn, were influenced by climate, land use, and riparian plant cover. Our estimates suggest that respiration pulses resulting from rewetting of IRES sediments could contribute significantly to annual CO2 emissions from the global stream network, with a single respiration pulse potentially increasing emission by 0.2–0.7%. As the spatial and temporal extent of IRES increases globally, our results highlight the importance of recognizing the influence of wetting‐drying cycles on respiration and CO2 emissions in stream networks.
Hydrogeological controls on spatial patterns of groundwater discharge in peatlands

Abstract. Peatland environments provide important ecosystem services including water and carbon storage, nutrient processing and retention, and wildlife habitat. However, these systems and the services they provide have been degraded through historical anthropogenic agricultural conversion and dewatering practices. Effective wetland restoration requires incorporating site hydrology and understanding groundwater discharge spatial patterns. Groundwater discharge maintains wetland ecosystems by providing relatively stable hydrologic conditions, nutrient inputs, and thermal buffering important for ecological structure and function; however, a comprehensive site-specific evaluation is rarely feasible for such resource-constrained projects. An improved process-based understanding of groundwater discharge in peatlands may help guide ecological restoration design without the need for invasive methodologies and detailed site-specific investigation. Here we examine a kettle-hole peatland in southeast Massachusetts historically modified for commercial cranberry farming. During the time of our investigation, a large process-based ecological restoration project was in the assessment and design phases. To gain insight into the drivers of site hydrology, we evaluated the spatial patterning of groundwater discharge and the subsurface structure of the peatland complex using heat-tracing methods and ground-penetrating radar. Our results illustrate that two groundwater discharge processes contribute to the peatland hydrologic system: diffuse lower-flux marginal matrix seepage and discrete higher-flux preferential-flow-path seepage. Both types of groundwater discharge develop through interactions with subsurface peatland basin structure, often where the basin slope is at a high angle to the regional groundwater gradient. These field observations indicate strong correlation between subsurface structures and surficial groundwater discharge. Understanding these general patterns may allow resource managers to more efficiently predict and locate groundwater seepage, confirm these using remote sensing technologies, and incorporate this information into restoration design for these critical ecosystems.
Genetic Evaluation for some Growth and Body Measurements Traits in Bronze Turkey Raised in Egypt

A total number of 50 males of bronze turkey were used in this study. Body weights (BW) in kg were recorded at 36, 40 and 44 weeks of age. Body measurements (BM) such as body length (BL), breast circumference (BC), keel length (KL) and shank length (SL) in cm were measured at 36, 40 and 44 weeks of age were also studied.

Estimates of Pearson correlations (rG) among predicted breeding values for most of traits studied in males of bronze ranged from low to high (but in general being high) and significantly positive.
Individually stretch cling film wrapped Kinnow mandarin under ambient storage

The experimental results revealed that the fruits treated in combination of curing, coating with neem oil (6.0%), Til oil (4.0%), mustard oil (8.0%), wax (2.5%), carbendazim (1000ppm) and wrapped with stretch cling film retained better performance in respect of physiological loss in weight (PLW), sensory qualities, least rotting per cent, higher juice recovery etc. under ambient conditions. The PLW was significantly less in T6 (curing + 2,4-D 500ppm + carbendazim 1000ppm + wrap.) of IFW fruits (3.28%) followed by T10 (curing + Til oil 4.0% + wrap.) fruits (4.87%) at the end of 12th week of ambient storage. The treatment of T9 (curing + mustard oil 8.0% + film wrapping) decreased the process of colour development even after 12th week of ambient storage. At the end of 12th week, less rotting per cent was observed in treatments T6, T7, T8 and T4 followed by T10 under ambient condition.
Mode Analysis and Fault-Tolerant Method of Open-Circuit Fault for a Dual Active-Bridge DC–DC Converter

A dual active-bridge (DAB) dc–dc converter is widely used in bidirectional high-power conversion, such as renewable energy system or train traction system. The open-circuit fault of DAB may threaten the system safety operation and should be eliminated in time. In this article, each fault mode of DAB is analyzed in detail. The transient operations and the load-carrying capacity are carefully analyzed. Based on the analysis, a DAB fault-tolerant method called “primary-side lower power secondary-side bypass arm” (PLP-SBA) is proposed. When the fault occurs in the primary side, the power of DAB is cut down, and when the fault occurs in the secondary side, the entire fault bridge arm is bypassed. The PLP-SBA method can ensure a certain load-carrying capacity after an open-circuit fault. A 5-kW DAB experimental platform is built to verify the correctness and effectiveness of the DAB mode analysis and PLP-SBA method.
Violent Crime in Bars: A Quantitative Analysis

Abstract Research suggests that some barroom settings create a milieu conducive to the outbreak of violence. Few studies, however, use a large national dataset to investigate the nature and prevalence of violence in bars. This article attempts to help fill this research gap by examining data on bar violence from the National Incident-Based Reporting System for the years 2011–2015. Findings show that compared to other National Incident-Based Reporting System (NIBRS) locations, murder, aggravated assault, and simple assault are more likely to occur in bars. Furthermore, males, Caucasians, African Americans, and people 18–34 years old are more likely to be victims of violent crime at bars. Implications for security practices and measures within drinking establishments are also addressed.
