Opis:
Purpose. To verify the relationship between stress indicators and the age and years of service of military firefighters from the fire rescue corps of the metropolitan area of the state of Sao Paulo. Methods. Forty military firefighters with the mean age of 37.9 ± 5.4 years, from the 1st, 2nd and 8th fire brigades of the metropolitan area of Sao Paulo participated in this study. All underwent clinical, physical and psychological evaluations to verify the relationship between the age and years of service with the variables of levels of stress (tension, depression, anger, vigor, fatigue, confusion and total stress) on workdays and on days off. Results. On workdays, the mean scores for tension, depression, fatigue and stress were overall higher compared to those on days off. The older the firefighter, the higher the levels of stress, depression, anger and total stress. The more years of service, the greater the depression and anger. Conclusions. The levels of stress were high on workdays. Chronological age and years of service influenced the increase in the scores of stress.

Opis:
Finding a niche journal for the submission of an academic paper can sometimes be a challenge for authors, and finding the right choice may involve a series of submissions and rejections. Emails from editors and journals related to the submission or rejection of a paper should be strictly related to these purposes, i.e., to inform authors that their paper has been received, outline the subsequent editorial handling or peer reviewer steps in the former, or the reasons for rejection in the latter. This paper highlights four cases of - in the author’s opinion - the abuse of such emails by COPE member journals and publishers (Emerald Publishing Ltd., Springer Nature, Elsevier, Wiley) to advertise for-profit English revision and editing services and/or conferences, as a way to maximize these emails for a dual purpose, namely to inform authors of submission-related aspects (valid communication) while also trying to obtain clients and thus business for non-submission-related aspects (invalid communication). Since an abuse of email-based communication for non-academic purposes is an ethics-related matter, there is a need for systematic research of this potential abuse of emails from both COPE member and non-member journals.

Opis:
This opinion paper puts forward arguments that reflect how science’s most elite prize, the Nobel Prize may be, despite its grand stature, somewhat out of touch with the functionality of grassroots science. There is a disconnect between limited fields of study to which the prize is awarded and the interdisciplinary nature of complex research. This is the first weakness. The second limitation is the focus on a single individual, occasionally on two or three when the prize is divided, even though much research is frequently collaborative. This is particularly true in the biomedical and natural sciences, which tend to involve individuals with multiple skills, each or all of whom may be equally deserving of the Nobel Prize, given their collective participation. The Nobel Prize also tends to display poor cultural, linguistic and gender representation and/or bias. Finally, retractions of papers by select Nobel Prize laureates suggest that even these elite academics are not immune to the ills of science and academic publishing and that affect all scientists in a complex global web.

In response to the destruction of the hatch of main battle tanks, as has been evidenced in the on-going Russo-Ukrainian War, when a bomb or other explosive device is dropped onto the tank or its turret from above, a protective structure that deflects the device from causing harm to the turret – and thus the tankers – is desirable. This concept paper discusses one possibility: a tank 'umbrella', which offers, at least in theory, protection to the turret and tankers.
Tocząca się wojna rosyjsko-ukraińska udowodniła potrzebę wynalezienia konstrukcji chroniącej czołg podstawowy, zwłaszcza jego wieżę, przed zniszczeniem przez bombę albo inny ładunek wybuchowy zrzucon z góry. Niniejszy komunikat z badań opisuje jeden z możliwych pomysłów – czołgowy „parasol”, który zapewnia, przynajmniej w teorii, ochronę wieży czołgu i czołgistów.

Opis:
This paper provides a synthetic sedimentological overview of themiddle Frasnian carbonate platform of Belgium and associated carbonate mounds. Carbonate mounds started usually in a relatively deep, quiet subphotic environment with a crinoid-coral-sponge assemblage, then reached the fair-weather wave base and the euphotic zone with an algal-microbial facies. The upper parts of themounds are characterised by lateral facies differentiation with the algal-microbial facies protecting a central sedimentation area with a dendroid stromatoporoids facies and fenestral limestone. The lateral facies reflect different kinds of input of reworked mound material in the proximal area, from transported fine-grained sediment to coarse-grained fossil debris. On the platform, environments range from the outer zone (crinoidal facies) to stromatoporoid-dominated biostromes and to the lagoonal area of the inner zones (subtidal facies with Amphipora floatstone, algal packstone, intertidal mudstone and laminated peloidal packstone and palaeosols). These facies are stacked in metre-scale shallowing-upward cycles. The larger scale sequential organisation corresponds to transgressions and regressions, whose cycles are responsible for differentiating a lower open-marine biostrome dominated unit from an upper lagoonal unit. The last regression- transgression cycle, responsible for the platform-scale development of lagoonal facies, can be correlated with an atoll-stage evolution of the carbonate mounds belonging to the Lion Member.

Opis:
A recent contribution published in this journal (Dias−daSilva and Ilha 2009) reported a dermal skull fragment indicating the presence of a putative plagiosauroid temnospondyl in the Lower Triassic Sanga do Cabral Formation of the Paraná Basin, Southern Brazil. The taxonomic assignation of this specimen was necessarily tentative as it was based on circumstantial evidence, specifically the presence of a dense pustular ornamentation over four partial dermal skull bones, consideration of the described taxa known to bear such ornamentation, and the stratigraphic and paleobiogeographic range of such taxa. Therefore, Diasda−Silva and Ilha (2009) could not be totally certain about the plagiosauroid affinities of the new specimen and ascribed it to ?Plagiosauridae. It was particularly difficult to make a precise osteological identification of the specimen and six alternative osteological interpretations were made in comparison to both Gerrothorax and Peltobatrachus (see Dias−da−Silva and Ilha 2009: fig. 2). In spite of the poor taxonomic resolution, the new specimen raised interesting questions regarding the presence of plagiosauroid stereospondyls in western Gondwana, as well as their evolutionary patterns, biostratigraphic and paleobiogeographic implications. After Dias−da−Silva and Ilha's (2009) contribution was published, new data from Damiani et al. (2009) raised the possibility of narrowing down the taxonomic identity of the plagiosauroid from Brazil. Accordingly, this brief report provides a more precise taxonomic assignation for this material.

Opis:
The aim of this paper was to summarize scientific literature on obesity in policemen through a systematic review of observational studies. For this purpose the following electronic databases were selected: Medline by Pubmed, CINAHL, and Scopus; and a manual search of the referenced studies concerning this topic was performed. There were no restrictions with respect to the year or language of the publication. Twenty-three studies were identified and 9 articles, considered as potentially relevant, were included. The labor time, shift and career progression promoted changes in body composition. Most of the policemen taking part in the studies included in this paper were overweight (BMI: 25.2–29.3), obese (body fat ≥ 25%), had increased waist (90.4–102 cm) and abdominal perimeters (18.9–90.5 cm), and had a higher risk of chronic disease, which is associated with depression and stress development. Interventional studies are needed for the purpose of proposing preventive and rehabilitation programs, which would result in providing physical and mental well-being, improvement of life quality and, especially, prevention of obesity related to police work.

Opis:
The fossil record of temnospondyls in South America has been greatly expanded in the last 10 years, increasing their overall significance. They occur in Argentina, Brazil, and Uruguay, and range from the Guadalupian to the Late Triassic. The Early Triassic temnospondyl record in southern Brazil is mainly composed of fragmentary specimens, usually represented by dermal skull bones from the Sanga do Cabral Formation. Some of these fragments were tentatively referred to Lydekkerinidae and Rhytidosteidae based on their characteristic ridge−grooved “spider−web” pattern of ornamentation. In this contribution we report, for the first time, a temnospondyl skull fragment with pustulated sculpturing pattern, which is tentatively ascribed to Plagiosauridae. This new record could indicate the presence of a new temnospondyl taxon for the Lower Triassic of South America.

Opis:
Underground, tube, subway or metro are common expressions used to describe a rapid transit system serving urban areas. Such a system uses dedicated rail corridors, can run underground or overground, and often includes tunnels and viaducts. Although there are 148 cities in the world with metro systems, each system is different, interms of layout, length, capacity, etc., as it serves different geographical and socioeconomical areas. In this context, the paper presents four European metro systems (Sofia, Warsaw, Lisbon, and Tyne and Wear), introduces the systems dimensions, rolling stock and ticketing strategies and compares similarities and differences between the systems. The analyses suggest a number of recommendations and improvements, which if implemented, could benefit other metro systems in Europe and beyond.
W języku angielskim występuje wiele określeń opisujących metro. System ten wykorzystuje dedykowane korytarze kolejowe, mogące pracować pod ziemią lub nad ziemią i często obejmuje tunele oraz wiadukty. Mimo że istnieje na świecie 148 miast mających systemy metra, każdy system jest inny pod względem układu, długości, pojemności itp., ponieważ występują w różnych układach geograficznych i systemach społeczno-ekonomicznych. W tym kontekście, artykuł prezentuje cztery europejskie systemy metra (Sofii, Warszawy, Lizbony i Tyne and Wear), przedstawia wymiary systemów metra, taboru, strategię biletową i porównuje podobieństwa i różnice pomiędzy nimi. Analizy wskazują wiele zaleceń i usprawnień, które jeżeli zostaną wdrożone, mogą przynieść zysk dla systemów metra w Europie i poza nią.

The exchange between 4f- and conduction-electrons are dealt within a molecular field approximation. An analytical magnetic state equation is derived and the magnetic behaviour discussed. The parameters of the model are estimated from a fitting of the inverse susceptibility of PrAl$\text{}_{3}$ given in the literature.

In this sense, it points out that such power was, in the golden years of the Revolution (the 60s and the 70s), based on the revolutionary aura and the charisma of its leaders (Fidel Castro, Che Guevara and others) and that, in the first decade of this century, it acquired new supported contours through the emergence of Social Diplomacy, i.e. cooperation in the field of social services (health, education and sports, among others), thus contributing.

Opis:
There are few reports in literature about the selectivity of postemergence application of herbicides for the control of eudicotyledon weeds (broadleaf) in chickpea. For this reason, the aim of this study was to investigate the selectivity of diphenyl-ether herbicides in chickpea influenced by the herbicides and application rates. A field experiment was conducted from February to June 2017 in Urutaí, state of Goiás, Brazil. Cultivar BRS Aleppo was used in the experiment. The experiment was set up in a randomized block design with 2 × 3 + 1 factorial arrangement and three replications. The first factor was herbicides (fomesafen and lactofen) with the second factor being herbicide rate (50, 75, and 100% of referenced rate) plus an untreated check as a comparison. The applied rates of herbicides were 250 and 180 g ⋅ ha–1 of fomesafen and lactofen, respectively. The selectivity of herbicides was evaluated according to agronomic characteristics (plant population, height, dry matter, number of pods per plant and 100-grain weight) and yields. Both herbicides, regardless of dosage, were selective in chickpea cultivation, even exhibiting leaf necrosis symptoms with visible injuries below 20% with no effect on yield.

Opis:
The axial skeleton is proportionally underrepresented in the fossil record of early dinosaurs, when compared to other skeletal parts (e.g., pelvic girdle and hindlimb). For instance, the axis is poorly known in early dinosaurs, which precludes a better understanding of this important anatomical structure. Therefore, the present contribution fills an important gap with a description of the axis of a new early dinosaur (CAPPA/UFSM 0179). The specimen was collected at the Buriol outcrop, a Triassic fossiliferous locality from southern Brazil (Candelária Sequence, Santa Maria Supersequence) biostratigraphically correlated to Carnian units, placing this specimen among the oldest dinosaurs worldwide. Notable features include the combination of a neural spine that bears an almost straight dorsal margin along its length and presence of an epipophysis. This axis arrangement is unique among Carnian dinosaurs, representing a new morphotype, though a similar morphology is observed in some early theropods. Indeed, a phylogenetic analysis nested the specimen within Theropoda. However, this outcome is probably biased by the large amount of missing data in CAPPA/UFSM 0179 and also due to the limited sampling of the axis in early dinosaurs, particularly among sauropodomorphs. As the specimen comes from the site that includes Buriolestes schultzi (an early sauropodomorph), it is quite plausible that CAPPA/UFSM 0179 might be referable to that taxon. If so, the specimen improves the anatomical knowledge of Buriolestes schultzi, given its axis is yet unknown. An alternative possibility to be considered is that the specimen would belong to a dinosaur not yet known in the Candelária Sequence, which would increase its dinosaur diversity for the outcrop, improving the Triassic dinosaurian record from Southern Brazil.

Opis:
High dose ion implantation was used to form polycrystalline silicide films on porous silicon with different native concentrations of light impurities (C and O). Porous silicon layers severalμm thick were implanted with 170 keV Cr$\text{}^{+}$ ions to fluences of 3×10$\text{}^{17}$ ions/cm$\text{}^{2}$ both at room temperature and 450ºC. Similar samples were implanted with 100 keV Co$\text{}^{+}$ ions to fluences of 2×10$\text{}^{17}$ ions/cm$\text{}^{2}$ at room temperature, 350ºC, and 450ºC. The formed silicide compounds were studied by Rutherford backscattering spectrometry, elastic recoil detection, glancing incidence X-ray diffraction, and four point-probe sheet resistance measurements. Selected Co implanted samples were analysed by cross-section transmission electron microscopy. Results show that the light impurities were partially expelled from the forming silicide layer. Combining cross-section transmission electron microscopy with ion beam methods it was possible to show that, in the implanted region, the porous structure collapses and densifies during implantation, but the underlying porous silicon remains intact. The layer structure, as well as the quality and type of the formed silicide, were found to depend on the original impurity level, implantation temperature, and annealing.
