    Opis:
    The aim of this work is to present a class of nonlinear controller with an exponential-type feedback in order to regulate the sulfate mass concentration via the input flow in a continuous stirred tank bioreactor of an anaerobic sulfate-reducing process. The corresponding kinetic terms in the bioreactor’s modeling are modeled by unstructured modeling approach, which was experimentally corroborated. A sketch of proof of the closed-loop stability of the considered system is done under the framework of Lyapunov theory. Numerical experiments are conducted to show the performance of the proposed methodology in comparison with a well-tuned sigmoid controller.

    Opis:
    The Yucatan Peninsula of Mexico is endemic with Chagas disease. The main vector responsible for Trypanosoma cruzi transmission is Triatoma dimidiata which is abundant in domestic, peridomestic and sylvan cycles. The abundance of vectors favours T. cruzi transmission and is a high risk for developing chronic chagasic cardiomyopathy (CCC). In the past 10 years, little information was available on parasite seroprevalence and the prevalence of CCC in the Yucatan Peninsula. In the present work, we studied two Mayan communities with a high abundance of T. dimidiata and a random serial sample of 233 patients with an altered electrocardiogram or cardiac failure admitted to the Regional Hospital. A homemade enzyme-linked immunosorbent assay and indirect immunofluorescence standardized techniques were used to detect anti-T. cruzi IgG. In addition, Mayan volunteers were monitored by electrocardiography. In the Mayan communities, 4.8% (3/63) subjects were positive for T. cruzi antibodies none of them presented electrocardiographic alterations, however in seronegative subjects were detected right or left ventricle hypertrophy in 25% (16/63). A remarkable finding was that 90% of the Mayan population recognized the vector and 65% of them had experienced contact with triatomines bites. At the Regional Hospital 0.42% (1/233) were positive for T. cruzi antibodies showing compatible diagnosis with CCC; the most frequent pathology in this population was hypertension in 65% (151/233) and the less frequent was dilated myocardiopathy 6% (14/233). In conclusion, the prevalence of T. cruzi infection and CCC can be considered low in Yucatan, Mexico.

    Opis:
    Detailed bed-by-bed sampling on an outcrop of the La Casita and Taraises formations in northeastern Mexico (San José de Iturbide, Nuevo León State) allows the delimitation of the Jurassic/Cretaceous boundary. The Late Tithonian was determined by the presence of the Crassicollaria Zone (Colomi Subzone). Underlying subzones (Remanei and Brevis) were not identified due to the scarcity and poor preservation of calpionellids. The Jurassic/Cretaceous boundary was defined by the acme of the small and spherical form of the species Calpionella alpina Lorenz in sample IT-120. The Berriasian was divided into two zones and five subzones: the Calpionella Zone (Alpina, Ferasini and Elliptica subzones) and the Calpionellopsis Zone (Simplex and Oblonga subzones). The facies studied indicate that deposition during the Tithonian occurred in a toe of slope environment with occasional deep shelf incursions. Near the Jurassic/Cretaceous boundary, a sea level drop is recorded and the facies indicate a slope environment with the occurrence of a breccia level. A general deepening of the environments recorded within the frame of the Elliptica Subzone where the deposits pass into basinal facies

    Opis:
    Under natural conditions, Trypanosoma cruzi infection is transmitted to mammals when faeces contaminated with metacyclic trypomastigotes gain access through skin lesions, mucosa or bite wounds. Natural infection of bugs with T. cruzi can vary greatly from less than 1% up to 70%, depending on triatomine species: in the case of Triatoma dimidiata, the percentage of infection is around 30%. In this work uses biological fluids (saliva and faeces) from Triatoma dimidiata to inoculate experimental animals once or multiple times, before inoculation with faeces contaminated with metacyclic trypomastigotes discrete type unit Ia (TcI). The site of infection was analyzed for histological changes based on hematoxile-eosine technique and toluide blue stain for mast cells. Inoculation with saliva led to the recruitment of eosinophils and mononuclear cells at the inoculation site, whereas inoculation with faeces led to the recruitment of neutrophils. Mice inoculated multiple times exhibited a strong inflammatory reaction from the first hour. Mono- or multi-exposure to T. dimidiata fluids before inoculation with metacyclic trypomastigotes helped to control the level of parasitemia. Previous contact with saliva or faeces of T. dimidiata reduces parasitemia in T. cruzi I -infected mice.

    Opis:
    It is very known that if the operator d/dx acts on each term into a convergent Fourier series (FS) then it may result a divergent series. This situation is remedied applying the symmetric derivative to FS, which implies the existence of the important Fejér-Lanczos factors. In this note, we show that the orthogonal derivative also leads to these factors.

    The Lanczos algorithm of minimized iterations shows that a polynomial verifying a three-term recurrence relation can be written as the determinant of a tridiagonal matrix, here we exhibit examples of this property. Besides, for several orthogonal polynomials, Cohen proved that their roots are the proper values of symmetric tridiagonal matrices; here we give examples of this Cohen’s result for the Legendre, Laguerre, and Hermite polynomials, which are important in applications to numerical analysis and quantum mechanics.

Besides, it is evident that the Hamiltonian secondary and tertiary constraints have relationship with the genuine constraints.

The Lanczos approach employs to ε= q_(n+1) as a new degree of freedom, thus the Euler-Lagrange equation for this new variable gives the Noether’s constant of motion. Torres del Castillo and Rubalcava-García showed that each variational symmetry implies the existence of an ignorable coordinate; here we apply the Lanczos approach to the Noether’s theorem to motivate the principal relations of these authors. The Maxwell equations without sources are invariant under duality rotations, then we show that this invariance implies, via the Noether’s theorem, the continuity equation for the electromagnetic energy. Besides, we demonstrate that if we know one solution of p(x)y''+q(x)y'+r(x)y=0, then this Lanczos technique allows obtain the other solution of this homogeneous linear differential equation.

    Opis:
    The corrosion enhancement due to plasma post-oxidation subsequent to plasma nitriding of the samples of low alloy annealed steel AISI 4140 was evaluated. The plasma nitriding was carried out at ≈570°C for 1-3 h in an atmosphere of 75% H₂ and 25% N₂. After this process post-oxidation at ≈450°C in a gas mixture, air and dry air-like was conducted for an hour. The treated samples were characterized using the XRD, SEM, AFM, potentiodynamic polarization and Vickers microhardness tests. The outcome of combined processes showed the presence of ε and γ' nitrided phases in the inner compound layer and in the outer one mostly of magnetite phase and barely visible of hematite one without using H₂ in the post-oxidation process. Also in these processes, the corrosion potential proved to be lower in the treated specimens than the untreated ones, and the corrosion current decreased up to one order of magnitude when treated in environment air and air-like ambient.

    Opis:
    With incident fluences of ≈ $10^{12}$ atoms/$cm^2$ aluminium samples have been plasma immersion ion implanted with either pure nitrogen or argon/nitrogen mixtures at temperatures around 450°C. X-ray diffraction studies have validated the formation of the cubic phase of AlN, in samples treated with both the gas mixtures and pure nitrogen. Likewise, the presence of the hexagonal phase of AlN has been detected when either pure nitrogen or a 70%N/30%Ar mixture have been used. The signature peak of AlN has also been confirmed by the Raman spectroscopy. The maximal microhardness values were found in samples treated with the mixture. The maximal roughness was achieved with the equal part mixture in all cases, although increasing with the implantation pulse width up to a 300 nm peak at 150 μs. The latter critical value remains invariant under the pure nitrogen plasma treatment, provided that implantation periods in the order of 4.5 h are carried out.

    Opis:
    The annealed low alloy 4140 steel samples have been nitrided for different treatment periods (1-6 h) in an RF inductive plasma discharge with very low bias voltage ( ≈ 400 V). The resulting nitrided layer has been observed by means of an optical microscope whereas the nitride phases have been characterised by X-ray analysis. The corrosion response, assessed by the potentiodynamic tests in the 3.5% NaCl solution, presents both higher noble potential values and lower corrosion rates when compared with the untreated sample. The Vickers microhardness tests values show an appreciable increment compared to that of the untreated sample. The process is characterized by a high overall efficiency because similar average Vickers tests values were obtained, no matter for how long the treatment was extended. Likewise, the scanning electron micrographs confirmed no appreciable size evolution of the compound layer microstructure at different times of treatment.

    Opis:
    Recent approaches to fault detection and isolation (FDI) for dynamic systems using methods of integrating quantitative and qualitative model information, based upon artificial intelligence (AI) techniques are surveyed. In this study, the use of AI methods is considered an important extension to the quantitative model-based approach for residual generation in FDI. When quantitative models are not readily available, a correctly trained artificial neural network (ANN) can be used as a non-linear dynamic model of the system. However, the neural network does not easily provide insight into model behaviour; the model is explicit rather than implicit in form. This main difficulty can be overcome using qualitative modelling or rule-based inference methods. For example, fuzzy logic can be used together with state-space models or neural networks to enhance FDI diagnostic reasoning capabilities. The paper discusses the properties of several methods of combining quantitative and qualitative system information and their practical value for fault diagnosis of real process systems.

    Opis:
    This work provides the values of both the static and the kinetic friction coefficients for chestnut (Castanea sativa Mill.) of Spanish origin. Knowledge concerning these coefficients has its main application in the study of agroindustrial structures and machinery with timber members in contact. This determination was developed taking into account the timber anisotropy to establish surfaces and directions of slipping. A modified direct shear test device was used to conduct the tests and reproduce the tribological system. This procedure was functional and reliable and considered suitable for standardizing the friction measurement between timber surfaces, since this device is widely distributed in geotechnical and materials laboratories and the European codes do not specify a procedure or device to carry it out. The average values obtained were 0.46 for the static coefficient and 0.33 for the kinetic one, without considering the surfaces and directions of slipping. These values ranged between 0.36 and 0.55 for the static friction coefficient and between 0.28 and 0.39 for the kinetic friction coefficient depending on the direction considered and also taking into account the anisotropy of the timber. A good correlation was obtained between both coefficients, thus allowing for the estimation of the kinetic coefficient from the static one.

    Opis:
    Agile development is a crucial issue within software engineering because one of the goals of any project leader is to increase the speed and flexibility in the development of new commercial products. In this sense, project managers must find the best resource configuration for each of the work packages necessary for the management of software development processes in order to keep the team motivated and committed to the project and to improve productivity and quality. This paper presents ReSySTER, a hybrid recommender system based on fuzzy logic, rough set theory and semantic technologies, aimed at helping project leaders to manage software development projects. The proposed system provides a powerful tool for project managers supporting the development process in Scrum environments and helping to form the most suitable team for different work packages. The system has been evaluated in a real scenario of development with the Scrum framework obtaining promising results.

    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.

    Opis:
    Recently, time series forecasting modelling in the Con‐ sumer Price Index (CPI) has attracted the attention of the scientific community. Several research projects have tackled the problem of CPI prediction for their countries using statistical learning, machine learning and deep neural networks. The most popular approach to CPI in several countries is the Autoregressive Integrated Mov‐ ing Average (ARIMA) due to the nature of the data. This paper addresses the Cuban CPI forecasting problem using Transformer with attention model over univariate dataset. The fine tuning of the lag parameter shows that Cuban CPI has better performance with small lag and that the best result was in = 1. Finally, the comparative results between ARIMA and our proposal show that the Transformer with attention has a very high performance despite having a small data set.

    Opis:
    The use of SBAS corrections for navigation, in both coastal waters and inland waterways, has already brought the attention of many European authorities, which are interested in its potential to complement/replace their DGPS radio beacon networks. The European GNSS Agency (GSA) has an active long-term trajectory working to foster the EGNOS adoption in maritime through the launch of several actions whose results will pave the way for the provision of maritime EGNOS services. In this line, GSA awarded the consortium ALG-Indra, ESSP and Alberding with the Specific Contract GSA/OP/07/13/SC24 ‘Support to Maritime Service Providers for the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations’. The main objective of this Specific Contract is to demonstrate the operational performance of the transmission of EGNOS corrections converted to Differential GPS corrections over the existing transmission infrastructure (AIS base stations/IALA beacons) in the Maritime and Inland Waterways (IWW) domains, while providing a detailed cost benefit analysis of the solutions proposed. This service may complement the current GNSS augmentation services exploiting synergies and benefiting from the current infrastructure and standards, facilitating the adoption of EGNOS by maritime and inland waterways authorities. Furthermore, the service has no impact at user level since the DGNSS corrections are transmitted over the existing infrastructure, in the same format and implementing the same integrity mechanisms required for traditional IALA beacons ([1]). This project will allow the maritime and IWW service providers to have a clear understanding about the technical, operational and economic feasibility of the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations.

    Opis:
    Globe artichoke (Cynara cardunculus L. var. scolymus (L.) Fiori) is an edible herbaceous perennial plant that plays an important economic role in Mediterranean agriculture. In recent years, extensive research, which aimed to characterize the phenolic profile of the most important globe artichoke cultivars in Italy, has been conducted. However, very little information is available on the phenolic composition of cultivars traditionally grown in Spain. In this work, six cultivars (‘Opal’, ‘Symphony’, ‘Concerto’, ‘Madrigal’, ‘Blanca de Tudela’ and ‘A-106’) cultured in Spain were characterized according to their phenolic content. The phenolic profile differed between cultivars, and also between flower parts. The major phenolic compound in all the different cultivars was chlorogenic acid. Of the six studied cultivars, ‘Madrigal’ had the highest phenolic content.

    Opis:
    Pochodzenie bagien Parku Narodowego Las Tablas de Daimiel w środkowej Hiszpanii jest związane z wypływem wód podziemnych ze zbiornika regionu zachodniego La Mancha. Wypływ tych wód do bagien zmalał z powodu intensywnej eksploatacji zbiornika. Postępujący zanik bagien skłonił do podjęcia działań zapobiegawczych, w postaci budowy szeregu małych zapór i przepompowywania wody do basenu Las Tablas. Głównym przedsięwzięciem zmierzającym do ratowania bagien było przesyłanie wody z innych basenów, jednak jej część była tracona w obrębie basenu bagiennego, ze względu na infiltrowanie do leżącego niżej zbiornika wód podziemnych. Infiltracja ta stała się ważnym parametrem przy projektowaniu metod utrzymania wody w basenie bagiennym, a także przy zintegrowanym zarządzaniu zasobami wodnymi, związanymi z obszarami bagiennymi. Rzeczywisty rozmiar strat jest trudny do określenia zarówno ze względu na złą jakość istniejących danych, jak i braku określenia różnych ważnych parametrów. Metodyka badań oparta na dziennym bilansie wód w basenie bagiennym pozwala określać te straty i może być stosowana przy zarządzaniu wodami Parku Narodowego.

    Opis:
    This paper addresses the design of a state estimation and sensor fault detection, isolation and fault estimation observer for descriptor-linear parameter varying (D-LPV) systems. In contrast to where the scheduling functions depend on some measurable time varying state, the proposed method considers the scheduling function depending on an unmeasurable state vector. In order to isolate, detect and estimate sensor faults, an augmented system is constructed by considering faults to be auxiliary state vectors. An unknown input LPV observer is designed to estimate simultaneously system states and faults. Sufficient conditions to guarantee stability and robustness against the uncertainty provided by the unmeasurable scheduling functions and the influence of disturbances are synthesized via a linear matrix inequality (LMI) formulation by considering H∞ and Lyapunov approaches. The performances of the proposed method are illustrated through the application to an anaerobic bioreactor model.

    Opis:
    Colorectal cancer (CRC) is the third most commonly diagnosed malignancy and the fourth most deadly cancer in the world for which surgery is the main treatment. Colorectal surgery can be performed through a wide incision in the abdomen or using minimally invasive surgical (MIS) techniques. Some of these techniques include transanal endoscopic microsurgery (TEM ), transanal minimally invasive surgery (TAMIS), transanal total mesorectal excision (TaTME ), and robot-assisted surgery. Studies increasingly confirm that resections using MIS techniques are safe, oncologically equivalent to open surgery and have better short-term results. These surgical approaches are, however, technically demanding and result in a steep learning curve. The main objective of this study is to review the different MIS techniques for colorectal surgery, as well as the training tools and programs designed to achieve the necessary surgical skills. Different training programs in colorectal surgery have been reported for the different surgical techniques analyzed. Most of these programs are based on training tools in the form of surgical simulators, physical and virtual, as well as the use of experimental and cadaveric models. However, structured training programs in minimally invasive colorectal surgery remain scarce, and there should be a consensus on the fundamental training aspects for the various surgical techniques presented. These training programs should ensure that surgeons acquire sufficient surgical skills to be competent in the development of these surgical techniques, improving the quality of the patient’s surgical outcomes.
    Rak jelita grubego (RJG) jest trzecim co do częstotliwości rozpoznawania nowotworem złośliwym na świecie, a także czwartą przyczyną zgonów na nowotwory złośliwe. Głównym elementem leczenia RJG jest operacja, którą można wykonać przez rozległe nacięcie powłok lub za pomocą technik minimalnie inwazyjnych. Do tych drugich należą: endoskopowa chirurgia transanalna (TEM ), przezodbytowa chirurgia minimalnie inwazyjna (TAMIS), przezodbytowe całkowite wycięcie mezorektum (TaTME ) oraz chirurgia wspomagana robotowo. Analizy danych potwierdzają, że techniki minimalnie inwazyjne są bezpieczne, równie skuteczne onkologicznie co techniki tradycyjne, a także wiążą się z szybszym powrotem chorych do pełnej sprawności. Ich wspólną cechą są niestety wysokie wymagania techniczne oraz długa krzywa uczenia. W artykule omówione zostały różne techniki minimalnie inwazyjne stosowane w leczeniu RJG oraz metody nauczania tych technik. Jak dotąd opracowano wiele sposobów szkolenia dla różnych technik operacyjnych. Większość opiera się na symulatorach chirurgicznych zarówno rzeczywistych, jak i wirtualnych oraz na wykorzystaniu modeli eksperymentalnych i preparatów z ludzkich zwłok. Niestety usystematyzowane modele szkolenia w minimalnie inwazyjnej chirurgii RJG są nadal rzadkością. Widać wyraźnie potrzebę opracowania konsensusu dotyczącego szkolenia w poszczególnych metodach operacyjnych. Tego rodzaju programy powinny zapewnić uczestniczącym w nich chirurgom zdobycie wiedzy pozwalającej na skuteczne wykonywanie zabiegów w celu zapewnienia pacjentom jak najlepszych efektów leczenia.

    Opis:
    We present an alternative method to detect and measure the concentration changes in liquid solutions. The method uses Digital Holographic Interferometry (DHI) and is based on measuring refractive index variations. The first hologram is recorded when a wavefront from light comes across an ordinary cylindrical glass container filled with a liquid solution. The second hologram is recorded after slight changing the liquid’s concentration. Differences in phase obtained from the correlation of the first hologram with the second one provide information about the refractive index variation, which is directly related to the changes in physical properties related to the concentration. The method can be used − with high sensitivity, accuracy, and speed − either to detect adulterations or to measure a slight change of concentration in the order of 0.001 moles which is equivalent to a difference of 0.003 g of sodium chloride in solutions. The method also enables to measure and calculate the phase difference among each pixel of two samples. This makes it possible to generate a global measurement of the phase difference of the entire sensed region.

In general, the quantum transmitter-receiver shows an experimental average quantum bit error rate of 30% using auto-homodyne detection with 0.25 photons per pulse in locking phase mode. The emulated final secret key rate measurements were 20 and 40 Kbps for minimum (30 Mbps) and maximum (90 Mbps) throughput, respectively, in a real traffic network using databases for the quantum keys generated by two true random number generators.

    Opis:
    n this work, morphology of Beta vulgaris L. cells permeabilized with 0.7 mM of Triton X-100® was evaluated using digital image processing and concepts of fractal dimension (perimeter- area relations). Important morphometric changes were found when the contact-time with chemical agent was increased.The size of cells decreased, the cells lost the roundness and their shape was more sinuous; this behaviour was a result of a probable shrinkage caused by the excess of exposure with the permeabili- zation agent. Morphology of B. vulgaris cells after permeabili- zation, exhibited a fractal nature since the slope of the ratio of the logarithm of the perimeter vs logarithm of the area was higher than unit. Fractal geometry of the cell morphology was affected as a re- sult of the exposure to Triton X-100®. Those changes can be attri- buted to the loss of turgor and structure of the cell wall.

    In this paper, explain the preparation of CaTiO3 ceramics synthesized by the solid-state reaction method. Calcium carbonate and titanium dioxide were high energy mixed in stoichiometric amounts, and the obtained mixture was calcined at different temperatures (800, 900, 1000 and 1300ºC) for 2h. The obtained samples were characterized by measurement of particle size, Energy Dispersive X-Ray (EDX) Analysis; differential thermal analysis, X-ray diffraction and SEM images. XRD patterns indicated that CaTiO3 ceramics with the structure of perovskite is obtained from calcined powders at 1,300°C for 2h. SEM images show the formation of a very fine and homogeneous morphology. The measured values of electrical resistivity were within the typical range of insulating materials and approach values corresponding to insulating ceramics.

    Here we report a new Early Pleistocene record of agamid lizards (Agamidae indet.) from the Spanish locality of Quibas (ca. 1.3–1.0 Ma), which represents the latest evidence of the family in Western Europe. Up to now, the family Agamidae was considered to have disappeared in this region at 1.8 Ma. This new record implies the survival of agamid lizards for a large part of the Early Pleistocene in the southernmost Iberian Peninsula, probably because of favourable climatic and environmental conditions. Consequently, the formerly detected Pliocene / Pleistocene boundary is no longer recognisable in the evolution of the herpetological assemblages in Western Europe.

    Opis:
    In maize plant breeding aimed at producing a hybrid, it is necessary to characterize the parents and hybrids by their agronomic aspects and grain quality so that the processing industry may offer consumers a quality product and also improve its efficiency. This study evaluated the viscoelastic parameters of masa and the chemical and texture properties of tortillas obtained from parent lines (M-54, M55, and CML-242), two single crosses (M54xM55 and M55xM54), and one hybrid (H-70). The morpho- logy of the maize grains and tortillas was analyzed using scanning electron microscopy. The firmness of masa obtained from CML-242 and H-70 maize was higher than that from the other maize genotypes. M-54 tortillas showed the lowest crude fiber content. Otherwise, tortillas obtained from the M55xM54 hard grain had the lowest fat content and extensibility, while H-70 tortillas showed an intermediate breaking point and extensibility. M-54 and M54xM55 tortillas were softer due to their more swollen starch granules. In contrast, rigid tortillas were obtained from CML-242 and H-70. Grain hardness causes different morphology in starch and tortilla of maize genotypes. However, grain hardness did not influence the characteristics of texture in tortillas.

    To determine the environmental impact, the assessment of the EuroPruning project strategy has been carried out in accordance with the checking and scooping list related to Directive 97/11/EC. Additionally, some suggestions and recommendations to prevent/minimize the hazard of accidents or negative interaction on surrounding have been elaborated (according to the suggested procedure in ISO 14001 methodology: risk definition and prevention action proposal). As a consequence, the results of the inspection during the demo tests taking place in different orchards/plantations regarding the performance of the machineries operation, farmers’ habits and pruning residues harvesting procedures have been presented, in order to diagnose and determine possible risks that may occur and influence negatively the local environment. Similar activities have been carried out during the storage tests and transportation processes.
    W celu określenia stopnia oddziaływania na środowisko strategii przyjętej w projekcie EuroPruning, polegającej na wykorzystaniu ściętych gałęzi z sadów i plantacji w celach energetycznych, przeprowadzono analizę w oparciu o zasady postępowania zawarte w dyrektywie 97/11/EC. Dodatkowo, w odniesieniu do procedury zawartej w metodologii ISO 14001: definicja ryzyka i proponowane działania prewencyjne, opracowano wskazówki i rekomendacje mające na celu eliminację lub ograniczenie ryzyka wypadku czy negatywnego oddziaływania na otoczenie zewnętrzne. W konsekwencji, przedstawiono wyniki inspekcji dokonanych podczas badań testowych przeprowadzanych w różnych sadach i plantacjach drzew owocowych (obejmujących działanie pracujących maszyn, nawyki sadownika oraz proces zbierania ściętych gałęzi) pod kątem identyfikacji oraz określenia zakresu zagrożeń, które mogą wystąpić i wpływać negatywnie na środowisko. Podobne działania przeprowadzono dla procesu magazynowania i transportu biomasy sadowniczej.

    Opis:
    Reactions between heavy-ions at various energy regimes produce many nuclear fragments which can be populated in highly excited states. The study of these fragments, detected at the end of their particle decay, is important to investigate nuclear forces and structure effects. In recent years there have been many efforts to extend these studies towards the drip-lines, i.e. to systems far from the β-stability valley, by using accelerated radioactive beams. The development of such infrastructures is accompanied by the development of more powerful detectors and associated electronics, capable to identify ions with very different sizes and kinetic energies. Here we give two examples which show how advanced arrays can contribute to the studies on nuclear phenomena. The examples come from the European FAZIA collaboration and from recent campaigns with the GARFIELD apparatus, the latter in operation at the INFN Legnaro Laboratory (Italy) where the SPES RIB facility is under construction.
