Níveis de sustentabilidade: Revisão sistemática da literatura
Authors: Feil Alexandre André
Published: December 2022

A compreensão dos níveis de sustentabilidade são essenciais para transformar os discursos em ações práticas nas tomadas de decisões e intervenções pontuais para a solução de questões insustentáveis. Neste sentido, este estudo objetivou analisar as correntes teóricas dos níveis (paradigmas) da sustentabilidade e seus limites de aplicabilidade. A metodologia vincula-se a abordagem qualiquantitativa e o procedimento técnico consiste na revisão sistemática da literatura. Os principais resultados apontam que os níveis da sustentabilidade defendidos na literatura centram-se no nível muito fraco, fraco, forte e muito forte. O nível muito fraco é atingido quando há uma substituição integral dos recursos naturais pelos recursos humanos; o nível fraco pela substituição ou compensação parcial, considerando o capital natural crítico um fator limítrofe, dos recursos naturais pelos recursos humanos; o nível forte quando há uma complementação dos diferentes tipos de capitais, que devem coexistir e se desenvolver mutuamente, tendo como apelo a conscientização e gestão ambiental; e o nível muito forte quando há a preservação integral dos recursos naturais e uma redução dos demais capitais. Nesta lógica, o nível fraco e muito fraco podem ser considerados insustentáveis e o nível forte e muito forte podem ser legitimados como sustentáveis. A ideia do desenvolvimento sustentável e da representação gráfica da sustentabilidade, por exemplo, podem ser entendidos como insustentáveis no longo prazo. Portanto, este estudo traz uma reflexão e um alerta à humanidade para repensar a direção desejada do nível de sustentabilidade para o futuro do sistema global, se o almejado é o sustentável ou o insustentável.

Globalny wymiar Europy — nowe zasady współpracy finansowej Unii Europejskiej z państwami sąsiedzkimi w ramach Europejskiej Polityki Sąsiedztwa
Authors: Kalicka-Mikołajczyk Adriana
Published: December 2022

W 2018 roku Komisja Europejska przeprowadziła ocenę skutków obejmującą działania zewnętrzne w ramach działu „Globalny wymiar Europy”, zawartego w wieloletnich ramach finansowych na lata 2014–2020, koncentrując się na głównych zmianach proponowanych w zakresie działań zewnętrznych, w tym na połączeniu kilku instrumentów w jeden, ale o szerszych ramach. Na podstawie analizy stwierdzono bowiem, że większość z dotychczas funkcjonujących instrumentów finansowania zewnętrznego Unii Europejskiej można by połączyć w jeden instrument o zasięgu ogólnoświatowym. Zgodnie z tym, co odnotowała Komisja, obecna struktura instrumentów finansowania zewnętrznego była zbyt złożona. Połączenie wielu instrumentów w jeden szeroki zapewniłoby możliwość racjonalizacji ich systemów zarządzania i nadzoru, a tym samym zmniejszenie obciążenia administracyjnego nałożonego na zainteresowane strony. Wdrożenie uproszczonego systemu nadzoru umożliwiłoby również właściwym instytucjom lepsze, bardziej kompleksowe spojrzenie na wydatki zewnętrzne UE. Szeroki instrument zapewniłby bardziej kompleksowe pod względem geograficznym i tematycznym podejście, ułatwiając tym samym wdrożenie różnych polityk na poziomie transregionalnym, wielosektorowym i globalnym. Ponadto dzięki połączeniu kilku instrumentów UE mogłaby ułatwić synergię oraz podejmowanie spójnych działań, przełamując schematyczne podejścia tematyczne i geograficzne. Z tych powodów 9 września 2021 roku ustanowiony został Instrument Sąsiedztwa oraz Współpracy Międzynarodowej i Rozwojowej.

Głównym zadaniem artykułu jest przedstawienie celów, zasad i mechanizmów współpracy finansowej między Unią Europejską a państwami sąsiedzkimi w ramach Europejskiej Polityki Sąsiedztwa od 2007 roku do chwili obecnej. Pozwoli to na udzielenie odpowiedzi na pytanie dotyczące podobieństw oraz różnic występujących w jej ramach w ostatnich piętnastu latach.

SOFT FREQUENCY REUSE FOR MILIGATION OF INTERCELLULER INTEREFERENCE
Authors: Mogylevych Dmytro , Papushoi Olha
Published: December 2022

Background. The appearance of femtocells in LTE networks has provided indoor coverage and overcome large data flows for operators. However, strong interference occurs in neighbouring femtocell users due to the limited available spectrum in cellular networks that transmit data in the same radio range. In densely deployed environments, interference issues in single-channel femtocells cause significant performance degradation. In this study, we mitigate inter-cell interference in femtocell networks by combining femtocells as a result of common interference and soft frequency reuse in downlink and uplink by moving and exchanging interfering physical blocks.

Objective. The purpose of the paper is to improve the efficiency of ensuring the quality of services in wireless networks by reducing any interference due to the distribution of traffic, which is able to provide uninterrupted connection to the user.

Methods. Enabling conditions for inter-cell interference mitigation in LTE-based femtocell networks with soft frequency reuse.

Results. Interference is a key issue in the deployment of LTE femtocells. Closely located femtocells interfere with each other if they transmit on the same frequency. Therefore, crossing femtocells and enabling them to allocate resources and reuse soft frequencies effectively reduces interference and prevents the loss of network resources. The scheme is triggered whenever the user's femto equipment experiences strong interference from neighbouring femtocells. By assigning a separate set of physical resource blocks to users at the edge of the cell, our scheme significantly reduces interference, which automatically increases cell throughput. The simulation results show the advantages of applying our scheme, in particular, the interference of the user's femto-equipment is reduced by 14% and the throughput is improved by 25%. That is, we observe a significant improvement in the performance of femtocells.

Conclusions. A femtocell crossing scheme with soft frequency reuse is presented to reduce interference between femtocells of LTE networks, which allows effectively ensuring the quality of service transmission in wireless networks by reducing interference and increasing performance through traffic distribution.
ACCURATE DETECTION OF MULTIPLE TARGETS BY UNIFORM RECTANGULAR ARRAY RADAR WITH THRESHOLD SOFT UPDATE AND AREA RESCANNING
Authors: Romanuke Vadim
Published: December 2022

Background. If the intensity of moving targets within a surveyed area is low, an optimal number of uniform rectangular array (URA) radar sensors is in either the minimally-sized URA (or close to it) or maximally-sized URA (or close to it), where the URA size is regulated by (symmetrically) turning off vertical and horizontal sensors. However, this does not guarantee detection of any target because sometimes the threshold detection, by which the main parameters of a pair of two targets are estimated, fails even by using the soft threshold approach when the threshold is gradually decreased while the detection fails.

Objective. In order to improve detection of multiple ground-surface targets by a URA radar, the goal is to decrease a number of detection fails, when targets are just missed. For this, the approach of threshold soft update and a set of quasioptimal URA sizes included  and  URAs are to be used by rescanning the area if the detection fails.

Methods. To achieve the goal, the functioning of the URA radar is simulated for a set of randomly generated targets, where roughly a half of the set is to be of single targets, and the other half is to be of pairs of targets. The simulation is configured and carried out by using MATLAB® R2021b Phased Array System ToolboxTM functions based on a model of the monostatic radar.

Results. Neither the soft threshold approach, nor the rescanning increase the detection accuracy. However, when either the soft threshold or rescanning is applied, or they both are applied, the number of detections is increased. The increment can be evaluated in about 2.7 %, but the expected high-accurate detection performance slightly drops. This is caused by that the soft thresholding and rescanning attempt at retrieving at least some information about the target instead of the detection fail.

Conclusions. Using the threshold soft update approach along with a more frequent rescanning decreases a number of detection fails. Besides, the soft thresholding and rescanning allow slightly decreasing the number of URA sensors sufficient to maintain the same detection accuracy by increasing the averaged number of single-target and two-target detections at least by 2.5 %. The increment in a number of detected targets on average is equivalent to increasing the probability of detection.

Published: December 2022

El hormigón es el material estructural más empleado. En el caso de sufrir una agresión térmica, sus propiedades mecánicas se ven modificadas, siendo en muchos casos necesaria su reparación para poder seguir utilizando la estructura. Teniendo en cuenta las premisas anteriores, el objetivo de la presente investigación es determinar la viabilidad del refuerzo de estructuras de hormigón con CFRP, después de haber sido sometidas a una agresión térmica. Para la realización del trabajo experimental se fabricaron probetas cilíndricas de 100 mm de diámetro y 200 mm de altura, la mitad de las cuales fueron sometidas a 250ºC. Una vez enfriadas, la mitad de las probetas patrón y la mitad de las probetas sometidas a 250ºC se reforzaron con fibra de carbono unidireccional SikaWrap-230 C, para posteriormente ensayar todas ellas a compresión y determinar la viabilidad del refuerzo. Los resultados obtenidos muestran que, debido a la agresión térmica, el hormigón pierde parte de su capacidad resistente, reduciéndose su resistencia máxima en un 26%. Una vez reforzadas las probetas, su resistencia máxima aumenta un 105% en el caso de probetas patrón y un 89,5% en el caso del hormigón sometido a 250ºC.AbstractConcrete is the most widely used structural material. In the case of suffering a thermal aggression, its mechanical properties are modified, being in many cases necessary to repair in order to be able to continue using the structure. Taking into account the above premises, the aim of the present research is to determine the viability of reinforcement of concrete structures with CFRP, after being subjected to thermal aggression. For the realization of the experimental work, cylindrical specimens of 100 mm in diameter and 200 mm in height were made, half of which were subjected to 250ºC. Once cooled, half of the standard specimens and half of the specimens subjected to 250ºC were reinforced with SikaWrap-230 C unidirectional carbon fiber, in order to subsequently test all of them in compression and determine the viability of the reinforcement. The results obtained show that due to the thermal aggression, the concrete loses part of its resistance capacity, reducing its maximum resistance by 26%. Once the specimens are reinforced, their maximum strength increases by 105% in the case of standard specimens and by 89.5% in the case of concrete subjected to 250ºC.

Reiterando que são pensamentos que envolvem humanidades, em que uma não se afirma sobre a outra, o viver sem governo também é horizente do pensamento anarquista; este texto procurar articular escritos de Ricardo Flores Magón, David Graeber e Piotr Kroptkin para pensar em princípios como a autogestão, a autonomia, o apoio mútuo e a livre associação em tempos brutos.
Diatomic Line Strengths for Fitting Selected Molecular Transitions of AlO, C2, CN, OH, N2+, NO, and TiO, Spectra
Authors: Parigger Christian G
Published: December 2022

This work communicates line strength data and associated scripts for computation and spectroscopic fitting of selected transitions of the diatomic molecules AlO, C2, CN, OH, N2+, NO, and TiO. For ease of use, the scripts for data analysis are designed for inclusion in various software packages or program languages. The accuracy of the data is of the order of less than one picometer, suitable for analysis of laser-induced fluorescence and laser-plasma spectra. Selected results demonstrate the applicability of the program for data analysis in laser-induced optical breakdown spectroscopy primarily at The University of Tennessee Space Institute, Center for Laser Applications. Representative spectra are calculated and referenced to measured data records.
A Practical Approach for Determining Multi-Dimensional Spatial Rainfall Scaling Relations Using High Resolution Time Height Doppler Data from a Single Mobile Vertical Pointing Radar
Authors: Jameson A.R.
Published: December 2022

Rain occurs over a wide range of spatial scales. The challenge is to connect certain fine scale needs to the available large scale observations from radars, satellites or coarse grid numerical weather predictions. This is the problem of rescaling of the rainfall. Whatever approach is used, it requires a knowledge of rainfall scales over a wide range of possible dimensions from tens of meters to kilometers. It is also desirable to have measurements at different locations and under different meteorological settings. Such measurements are not necessarily readily obtainable, requiring extensive and usually fixed and expensive networks of multiple instruments over large areas. A mobile and less expensive alternative is the, Micro-Rain Radars (MRR). We illustrate this using observations of the Doppler spectra of falling rain every 10 m vertically and 10 second temporally over intervals varying from 15 up to 41 minutes collected at Wallop’s Island Virginia and Charleston South Carolina using two different MRR. An objective method to estimate advection velocity was developed so that the time-height profiles could be transformed into height-horizontal distance profiles in order to calculate scaling relations. Thus, MRR and other Doppler radars may obviate the need for networks of instruments.
Numerical Response of Owls to Dampening of the Population Cycles of the Small Mammals in Latvia

Published: December 2022

Strong numerical and functional response of owls to voles in cyclic environments is well known, but there is insufficient knowledge from boreonemoral region, in particular, with depleted populations of the small mammals. In this study we describe the dynamics of the small mammal population in Latvia from 1991 to 2016 and link them to owl population characteristics. We used food niche breadth, number of fledglings and population trends to describe the numerical response of six owl species to dampened small mammal population cycles. We found temporarily in-creasing food niche breadth in tawny and Ural owls. There were no other responses in tawny owl, whereas the breeding performance of three forest specialist species – pygmy, Tengmalm`s and Ural owls – were similar to vole crash years in Fennoscandia. Moreover, the populations of forest specialist owls are decreasing and the change in Ural owl can be attributed to the depletion of small mammal populations. We found evidence of carry-over effect in eagle owl arising from strong correlation of declining breeding performance with the small mammal abundance indices in previous autumn. We conclude that dampening of the small mammal population cycles is an important covariate to overwhelming impacts of habitat destruction with stronger response in more specialized (to prey or habitat) species.
Tourism in Geography Textbooks in Secondary Education and High School. The Case of the Balearic Islands.
Authors: Coll Ramis Miquel Angel , Picó Gutiérrez Victor , Ordinas Garau Antoni
Published: December 2022

Since the mid-20th century, tourism has become a strategic activity for the economy of the Balearic Islands, causing profound social, territorial and environmental transformations. This fact challenges local society, which must be aware of its environment in order to better face the future challenges posed by this economic activity. With this goal, the official curriculum has been analyzed, making it possible to ascertain the approach with which this subject is taught by the administration and what objectives are set. Furthermore, a review was carried out of the contents of geography textbooks in the third year of ESO and the second year of Baccalaureate, which correspond to the educational stages in which tourism aspects appear.

Published: December 2022

The primary contributor to global warming has been the careless usage of fossil fuels. Urbanization's threat to the depletion of these resources has made it necessary to find alternatives due to the rising demand. Four different forms of biofuels are now available and constitute a possible replacement for fossil fuels. The first generation of biofuels is generated from the edible portion of biomass, the second generation is made from the non-edible portion of biomass, the third generation is made from algal biomass, and the fourth generation is made using molecular biology to improve the algal strain. Second generation biofuels are extremely important because they are derived from non-edible biomass, such as agricultural and agro-industrial wastes rich in cellulose, hemicellulose, pectin, and starch impregnated with lignin, and are hydrolyzed after delignification by physio-chemical or biological pretreatments using ligninases. There has been a lot of research on their production using chemical and enzymatic hydrolysis, but it has not been economically viable in comparison to first generation biofuels due to the formation of several inhibitors with chemical hydrolysis and the high cost of the enzymes. Furthermore, the need for multiple enzymes due to the various types of carbohydrates in the feedstocks makes the enzymatic process too expensive. This article examines the enzymes involved in the hydrolysis of feedstocks for the production of second generation bioethanol, a highly acceptable biofuel.

Nanoparticles (NP), Nanoaerosols (NA), ultrafine particles (UFP), and PM0.1 (particles with a diameter ≤ 0.1 µm or 100 nm) are interchangeably used in the field of atmospheric studies. PM0.1 are emitted from both natural and anthropogenic sources. The main emission sources of PM0.1 are combustion processes, including biomass and fossil fuel. Moreover, secondary formation via atmospheric photochemical reactions can also occur depending on meteorological conditions and the suspended pollutant species. Identifying the physical and chemical characteristics and spatial and temporal variations is vital in terms of understanding the effect of NPs on the environment, the global climate, and human health risks. This review article summarizes recent research on PM0.1 in Thailand. The review involves peer-reviewed papers from Scopus and the Web of Science databases, and includes the most recently published articles in the past ten years (2013-2022). UFPs mainly come from the combustion processes such as motor vehicles. The high mass concentration of PM0.1 that occurs during the dry season in which open fires depend on the specific region of Thailand. Particulate pollution from local and cross-border countries also needs to be considered in terms of the concentrations of ambient nanoparticles. The overall conclusions reached will likely have a beneficial long-term impact on achieving a blue sky over Thailand through the development of coherent policies and managing new air pollution challenges and sharing knowledge with a broader audience.

Background: Anthracyclines form the backbone of many systemic chemotherapy regimens but dose-limiting cardiotoxicity can also lead to reduction in cardiac function and an increased risk of heart failure. Methods: This review was conducted in accordance with PRISMA guidelines and registered on PROSPERO (CRD42022373496). Results: 26 studies met the eligibility criteria including a total of 910 patients. Overall reduction in pooled mean left ventricular ejection fraction (LVEF) post‐anthracyclines in the placebo arms of included randomised-controlled trials was 4.6% (95% CI, 2.7 to 6.6). The trend in LVEF showed a progressive decline until approximately 180 days after which there was no significant change. Those receiving a cumulative anthracycline dose 300 mg/m2 experienced a more profound reduction. The risk of a 10% absolute decline in LVEF from baseline or decline to an LVEF below 50%, the overall pooled risk was 16% (95% CI: 11 to 21; I2 = 77%). Sensitivity analyses by baseline LVEF and trastuzumab treatment status did not yield significant differences. Conclusion: While the mean LVEF decline in patients without cardioprotective therapy was clinically small, a vulnerable subset experienced significant impairment. Further research to best identify those who benefit most from cardioprotective therapies when receiving anthracyclines are required.

Al-6%Mg-Sc-Zr alloys with the total ratio of Sc + Zr = 0.32 wt.% make up the target of this research. The content of scandium and zirconium varied with an increment of 0.02%. The alloys were produced by induction casting. Their ultrafine-grained (UFG) microstructure was formed with Equal Channel Angular Pressing (ECAP). Such cast alloys have a homogeneous macrostructure formed by small equiaxed grains in the central part of the ingot and columnar crystals along the edges of the cross section. After ECAP, the average grain size in the alloy specimens is 0.5–1 µm. The average grain size does not depend on the ratio of Sc and Zr in these alloys. Superplasticity tests were performed at temperatures ranging from 300 to 500 °C and at a strain rate varying between 3.3·10-3 and 3.3·10-1 s-1. UFG Al-6%Mg-0.20%Sc-0.12%Zr and Al-6%Mg-0.18%Sc-0.14%Zr alloys exhibit the highest superplasticity. It was suggested that changes in Sc:Zr ratio affect spatial distribution and composition of the following precipitating particles: Al3Sc, Al3Zr, Al3(ScxZr1-x). An increase in Zr concentration is shown to reduce the susceptibility of UFG alloys to cavitation fracture.
A Scrutiny of Landmark Experiments Disproves Photonic Quantum Nonlocality
Authors: Vatarescu Andre
Published: December 2022

A physical scrutiny of experimental results published in Physical Review Letters (December 2015, M. Giustina, et al., Phys. Rev. Lett. 115, 250401, and L. K. Shalm et al., Phys. Rev. Lett. 115, 250402) is undertaken. These articles reported that measured outcomes were fitted with quantum states possessing a dominant component of non-entangled photons, thereby contradicting their own claim of quantum nonlocality. With probabilities of photon detections lower than 0.1 %, the alleged quantum nonlocality cannot be classified as a resource for developing quantum computing devices, despite recent publicity. Experimental evidence of a feasible process for quantum-strong correlations has been identified (M. Iannuzzi, et al., Phys. Lett. A, 384 (9), 126200, 2020) in terms of correlations between independent and multi-photon states evaluated as Stokes vectors on the Poincaré sphere. As single-photon sources are not needed, the design and implementation of quantum computing operations will be significantly streamlined.
Liquid Biopsy and Glioblastoma
Authors: Eibl Robert , Schneemann Markus
Published: December 2022

Glioblastoma is the most common and malignant primary brain tumor. Despite a century of research efforts, the survival of patients has not significantly improved. Currently, diagnosis is based on neuroimaging techniques followed by histopathological and molecular analysis of resected or biopsied tissue. A recent paradigm shift in diagnostics ranks the molecular analysis of tissue samples as the new gold standard over classical histopathology, thus correlating better with the biological behavior of glioblastoma and clinical prediction, especially when a tumor lacks the typical hallmarks for glioblastoma. Liquid biopsy aims to detect and quantify tumor-derived content, such as nucleic acids (DNA/RNA), circulating tumor cells (CTC), or extracellular vesicles (EV) in biofluids, mainly blood, cerebrospinal fluid (CSF), or urine. Liquid biopsy has the potential to overcome the limitations of both neuroimaging and tissue-based methods to identify early recurrence and to differentiate tumor progression from pseudoprogression, without the risks of repeated surgical biopsies. This review highlights the origins and time-frame of liquid biopsy in glioblastoma and points to recent developments, limitations and challenges of adding liquid biopsy to support the clinical management of glioblastoma patients.

Background: Little is known about the natural history of immunoglobulin (Ig) E-mediated diseases in preterm infants, further hampered by the lack of noninvasive investigations. We aimed at developing a non-invasive tool for the study of IgE and eosinophil-derived neurotoxin (EDN) in neonatal fecal samples and evaluating its predictive value for the development of IgE-mediated diseases (cow’s milk allergy, asthma, or atopic dermatitis) during the first year of life. Methods: We developed a stool extraction protocol, followed by freeze-drying and solubilization. sIgE responses were investigated in neonatal fecal samples from 21 preterm infants with a 300-allergen multiplex containing whole and molecular allergens and confirmed by capillary Western blot with nano-immunoassay. The local eosinophilic component was investigated by measuring the concentration of EDN. Results: The multiplexed allergen assay detected sIgE in all samples. Confirmation was obtained with Western blot. Frequency and levels of sIgE in neonatal fecal samples differed between infants who developed IgE-mediated diseases and controls. Neonatal fecal sIgE directed to milk proteins predicted later development of cow’s milk allergy (specificity 88%, sensitivity 78%). Allergen specificity of neonatal fecal sIgE was associated with later development of cow’s milk allergy and asthma. Neonatal fecal EDN levels predicted the development of IgE-mediated diseases (sensitivity 100%, specificity 75%). Conclusion: Non-invasive investigation of neonatal fecal sIgE is a promising tool for the prediction of subsequent development of IgE-mediated diseases.
