Opis:
The article discusses the results of research on radiometric processing of multitemporal satellite images in order to monitor deforestation in the Amazon region. Images acquired by Landsat ETM+ and CBERS−2 were used. The proposed algorithms enabled an objective analysis of deforestation and regeneration distribution within tropical rainforests. The advantage of the method is its simple algorithm and lack of need for atmospheric correction.

Opis:
The Galinha tracksite reveals a sequence of Bajocian–Bathonian limestones belonging to the Serra de Aire Formation (West−Central Portugal) and is one of the few sites in the world where Middle Jurassic sauropod dinosaur tracks can be found. This tracksite is characterised by the presence of long, wide gauge sauropod trackways, the Middle Jurassic age of which suggests these dinosaurs were more widely distributed over time than previously thought. Two trackways contain unique pes and manus prints with morphologies that allow a new sauropod ichnotaxon to be described: Polyonyx gomesi igen. et isp. nov. On the basis of different manus/pes prints and trackway features, the proposal is made to subdivide Sauropodomorpha ichno−morphotypes into five groups: Tetrasauropus−like, Otozoum−like, Breviparopus/Parabrontopodus−like; Brontopodus−like, and Polyonyx−like. Polyonyx gomesi igen. et isp. nov. is thought to represent a nonneosauropod eusauropod, with a well developed manus digit I. The posterior orientation of this digit print suggests they were made by a eusauropod dinosaur with a posteriorly rotated pollex. The manus print morphologies observed in two trackways suggest a stage of manus structure intermediate between the primitive non−tubular sauropod manus and the tubular metacarpal arrangement characteristic of more derived sauropods. The low heteropody (manus:pes area ratio 1:2) of the trackway renders it possible they could have been made by eusauropods such as Turiasaurus riodevensis, which has a similar manus:pes area ratio. The Polyonyx igen. nov. trackway was made by non−neosauropod eusauropod, and suggests that wide gauge sauropod trackways were not exclusively made by Titanosauriformes.

Opis:
A new technique to enhance single-stage operational transconductance amplifiers (OTAs) is presented. Enhanced DC gain and reduced input parasitic capacitances are achieved by employing two input fully-differential voltage combiners, i.e. a combination of transistors in common-drain and common-source configurations operating as a preamplifier stage. Simulation results show that the input capacitance can be as small as 195 fF (corresponding to a 46 % reduction) while achieving a GBW of 1982 MHZ (@ CL = 1 pF) with a PM of about 60⁰. The complete amplifier dissipates only 1.78 mW corresponding to a figure-of-merit (FoM) of 1115 MHz-pF/mW.

Opis:
Rigid pipelines installed in offshore structures for oil and gas production are built from pipe sections connected by circumferential welds. Such welds are generally points of stress concentration and therefore the regions that most demand periodic inspection. The weld geometry and the inspection speed required for in service inspection are the main challenges associated to the inspection procedure. In the present work an eddy current transducer with sensing coils placed orthogonally and connected in differential mode was introduced to evaluate fatigue cracks in weld root. A dedicated embedded electronic hardware was developed to drive the transducer and measure the electrical complex impedance of the coils and was specifically designed for operation under autonomous in-line inspection tool in a speed range between 0.5 – 1.0 m/s. The achieved results have confirmed that the introduced eddy current transducer is a potential solution for fatigue crack detection in irregular surfaces like weld root, while the hardware developed presented a reasonable SNR and achieved the data rate required to be incorporated in an autonomous in-line inspection tool.
Sztywne rurociągi instalowane w morskich konstrukcjach do produkcji ropy i gazu budowane są z odcinków rur połączonych spoinami obwodowymi. Takie spoiny są zwykle punktami koncentracji naprężeń, a zatem regionami, które w największym stopniu wymagają okresowej kontroli. Geometria spoiny i prędkość kontroli wymagana do przeprowadzenia badania serwisowego stanowią główne wyzwania związane z procedurą inspekcji. W niniejszej pracy, w celu oceny pęknięć zmęczeniowych w rdzeniu spoiny, zaproponowano przetwornik wiroprądowy z cewkami pomiarowymi umieszczonymi ortogonalnie i połączonymi różnicowo. Opracowano specjalny wbudowany system elektroniczny do sterowania przetwornikiem i pomiaru impedancji złożonych cewek elektrycznych. System został zaprojektowany specjalnie do pracy jako autonomiczna jednostka inspekcji linii w zakresie prędkości od 0,5 do 1,0 m/s. Uzyskane wyniki potwierdziły, że wprowadzony przetwornik wiroprądowy jest potencjalnym rozwiązaniem umożliwiającym wykrywania pęknięć zmęczeniowych na nieregularnych powierzchniach, takich jak rdzeń spoiny. Ponadto opracowany sprzęt zapewnia odpowiedni współczynnik stosunku sygnału do szumu SNR i osiąga prędkość transmisji wymaganą dla zastosowania w jednostkach niezależnej kontroli w linii.

Opis:
The aim of this study was to verify the effect of a physical activity (PA) program on musculoskeletal pain and related symptoms in different body regions among workers. Methods. The intervention study lasted 6 months. The training sessions were given during work time. The intervention group (TOI) (n = 39) participated in 10–15 min of physical exercise training 3 times a week and focused on stretching exercises and general strength. The reference group (TOR) (n = 31) were asked to continue their daily activities. Musculoskeletal pain was assessed with the standardized Nordic questionnaires for analyzing musculoskeletal symptoms. Evaluations were performed at baseline and at the end of the intervention. Results. After the intervention, the TOI obtained some significant results regarding a decrease in the intensity of pain in some of the body regions evaluated, such as elbow (p = .03) and dorsal region (p = .015). In comparing the TOR and TOI after the 6 months of the PA program, we can verify that in the elbow and in the thigh/hip regions, the pain intensity decreased significantly; additionally, there is some evidence to suggest statistically significant results in the neck region (p = .063). Conclusion. Our intervention seems to have reduced musculoskeletal pain and related symptoms in factory workers.

Opis:
In agriculture, the mixing of pesticides in tanks is a common practice. However, it is necessary to previse possible physical-chemical implications of this practice, which may affect the efficiency of the treatments performed. Therefore, the objective of this study was to evaluate the effects of the addition of acaricide to insecticidal spray mixtures on the formation of spray droplets and the interaction with citrus leaves. The experimental design was totally randomized, in a (2 × 3 + 1) factorial scheme for seven treatments. Factor A corresponded to the spray mixture used (isolate or in the mixture). Factor B corresponded to the insecticides tested (lambda-cyhalothrin + thiamethoxam, phosmet, and imidacloprid) and the control consisted of a spray mixture with spirodiclofen only. Nine replications were performed for characterization of the spray droplet size spectrum and four replications for the analysis of the surface tension and the contact angle. The mixture of pesticides showed positive results in terms of application safety. The addition of acaricide to insecticide spray mixtures reduced the surface tension and contact angle of droplets on the adaxial surface of orange leaves. There was an increment in volume median diameter (VMD), a significant reduction in the volume of droplets with drift-sensitive size and improvement in the uniformity of droplet size. Therefore, the addition of acaricide to an insecticide spray mixture positively influenced spray droplet formation and the interaction with citrus leaves providing better coverage and droplet size fractions with an appropriate size for safe and efficient application.

This article presents a novel method to the utilize topological representation of a path, thatpath that is created from sequences of images from digital cameras and sensor data from range sensors. A topological representation of the environment is created by leading the robot around the environment during a familiarisation phaseLeading the robot around the environment during a familiarisation phase creates a topological representation of the environment. While moving down the same path, the robot is able to localise itself within the topological representation that is has been previously created. The principal contribution to the state of the art is that, by using a topological representation of the environment, individual 3D data sets acquired from a set of range sensors need not be registered in a single, [Global] Coordinate Reference System. Instead, 3D point clouds for small sections of the environment are indexed to a sequence of multi-sensor views, of images and range data. Such a registration procedure can be useful in the construction of 3D representations of large environments and in the detection of changes that might occur within these environments.

Opis:
In this work, we discuss theoretically the formation of the Tamm plasmon/exciton-polariton hybrid states in an (Al,Ga)As microcavity and their modulation by surface acoustic waves. The modulation of the Tamm plasmon/exciton-polariton states origins in the change of the excitonic band gap energy and the thickness change of the sample structure layers due to the induced strain fields by surface acoustic waves. The frequency f_{SAW} of the acoustic modulation of the Tamm plasmon/exciton-polariton states is limited by the thickness of the upper distributed Bragg reflector. For the Tamm plasmon/exciton-polariton states in Al_xGa_{1-x}As/GaAs structures f_{SAW} is in the range of 370 MHz while f_{SAW} in GHz range is possible for the parametric Tamm plasmon/exciton-polariton states. In both cases, the acoustic modulation is several meV for typical acoustic power levels.

Opis:
Purpose: of this paper was to review and summarize significant papers related to the development and characterization of lignin-containing adhesives: polyurethane and epoxy types. In the last decades, several efforts have been dedicated on the development of renewable raw materials for polymer synthesis, mainly due to petroleum depletion and sustainability. In this context, lignin emerged as a potential candidate to substitute fossil-based raw materials in adhesive synthesis and formulations. Design/methodology/approach: Recent and other relevant papers were reviewed, aiming to identify the main advantages and limitations involved in lignin incorporation into epoxy and polyurethane adhesives formulations. First, effects of unmodified lignin addition were presented. Afterwards, the main lignin chemical modification methods were presented and discussed, based on thermomechanical results. Findings: Incorporation of unmodified lignin usually is limited to 30 %wt., otherwise mechanical properties are drastically affected as consequence of poor lignin solubility and excessive brittleness. Lignin chemical modification can be used to increase the reactivity of hydroxyl groups and/or add new moieties in its molecular structure, improving solubility and thermomechanical properties of cured adhesives. Practical implications: In the last years, some industrial plants started to operate and produce technical grade lignin at industrial scale, with reproducible properties and controlled molecular structure. Therefore, increasing efforts have been dedicated from researchers and chemists to develop lignin-based technologies, in which this work can directly contribute with. Originality/value: As consequence of the high content of phenol groups in its molecular structure, lignin was mostly applied on the development of phenolic resins applied as wood adhesives. For the first time in the literature, this work summarizes the advances related to synthesis and characterization of polyurethane and epoxy, applied as adhesives. Results can support the development and application of biobased, as well as contribute to the revalorization of this valuable and readily available biomass.

Opis:
Purpose: The vestibular system is the part of the inner ear responsible for balance. Vertigo and dizziness are generally caused by vestibular disorders and are very common symptoms in people over 60 years old. One of the most efficient treatments at the moment is vestibular rehabilitation, permitting to improve the symptoms. However, this rehabilitation therapy is a highly empirical process, which needs to be enhanced and better understood. Methods: This work studies the vestibular system using an alternative computational approach. Thus, part of the vestibular system is simulated with a three dimensional numerical model. Then, for the first time using a combination of two discretization techniques (the finite element method and the smoothed particle hydrodynamics method), it is possible to simulate the transient behavior of the fluid inside one of the canals of the vestibular system. Results: The obtained numerical results are presented and compared with the available literature. The fluid/solid interaction in the model occurs as expected with the methods applied. The results obtained with the semicircular canal model, with the same boundary conditions, are similar to the solutions obtained by other authors. Conclusions: The numerical technique presented here represents a step forward in the biomechanical study of the vestibular system, which in the future will allow the existing rehabilitation techniques to be improved.

Opis:
The Jones-Wilkins-Lee (JWL) equation of state parameters for ANFO and emulsion-type explosives have been obtained from cylinder test expansion measurements. The calculation method comprises a new radial expansion function, with a non-zero initial velocity at the onset of the expansion in order to comply with a positive Gurney energy at unit relative volume, as the isentropic expansion from the CJ state predicts. The equations reflecting the CJ state conditions and the measured expansion energy were solved for the JWL parameters by a non-linear least squares scheme. The JWL parameters of thirteen ANFO and emulsion type explosives have been determined in this way from their cylinder test expansion data. The results were evaluated through numerical modelling of the tests with the LS-DYNA hydrocode; the expansion histories from the modelling were compared with the measured ones, and excellent agreement was found.
