Jak zwracamy się do osób nieznajomych? Granica między swoim a obcym we współczesnej polszczyźnie
Authors: Kawamoto Yumeko
Published: March 2023

The subject of this article is the manner of addressing strangers in Polish. In order to verify the current use of the language in this regard, two research methods were used: a survey method and an analysis of comments on a website aimed at the business community. As the respondents of the survey indicated, the contemporary Polish language speakers recognise the importance of the traditional border of officiality when choosing the appropriate forms of address. However, a problem in communication arises when the conceptual opposition of the official / unofficial intersects with the opposition of ours / others. This problem is sometimes observed in a business conversation, in which a recruiter addresses a job candidate using Polish ty form from the first contact and treats them as a person on the “our” side. The analysis of the comments from the internet showed that the relationship between the recruiter and the candidate basically remains between strangers and it is better to avoid the use of unofficial forms, especially those which use the addressee's first name.
Harpun, pan mysz i Arnold Mocny – przykłady metafor męskości w felietonach Małgorzaty Domagalik
Authors: Majewska Magdalena
Published: March 2023

The paper presents the feminist and the traditional metaphors of masculinity using examples from Małgorzata Domagalik’s subjective texts. The columnist shows three types of male personalities: Harpun (Harpoon), pan mysz (mister mouse) and Arnold Mocny (Arnold the Strong). Harpoon is a weapon in the fight against stereotypes whereas mister mouse is man out of his depth, who doesn’t show any traditional masculine traits. On the other side Arnold the Strong is a personification of male strength. The methodological structure is based on a linguistic and cultural analysis of metaphors shown in Małgorzata Domagalik’s columns.

Objectives

Given that SARS-CoV-2 antigen tests will represent a pillar for supporting or surrogating molecular testing in the endemic period, we report here the clinical performance of the new SNIBE Maglumi SARS-CoV-2 antigen fully-automated chemiluminescent immunoassay (MAG-CLIA SARS-CoV-2 Ag).

Methods

The study population consisted of 181 subjects (mean age 61 ± 21 years; 92 females) undergoing coronavirus disease 2019 (COVID-19) testing at the local diagnostic facility, from December 2022 to February 2023. Routine diagnostic practice involved the collection of a double nostril nasopharyngeal swab, analyzed in duplicate with SARS-CoV-2 antigen (MAG-CLIA SARS-CoV-2 Ag) and molecular (Altona Diagnostics RealStar SARS-CoV-2 RT-PCR Kit) tests.

Results

A significant Spearman’s correlation was found between MAG-CLIA SARS-CoV-2 Ag and mean Ct values of SARS-CoV-2 E and S genes (r=−0.95; p<0.001). In all nasopharyngeal samples, the area under the curve (AUC) of MAG-CLIA SARS-CoV-2 Ag was 0.86 (95% CI, 0.81–0.90), with 0.71 sensitivity and 1.00 specificity at 7 ng/L cut-off, increasing to 0.98 (95% CI, 0.96–1.00) AUC and 0.96 sensitivity (with 0.97 specificity) in high viral load samples. When SARS-CoV-2 N protein concentration was replaced with raw instrumental readings (i.e., relative light units [RLU]), the AUC in all samples increased to 0.94. A RLU value of 945 was associated with 88.4% accuracy, 0.85 sensitivity, 0.95 specificity, 0.77 negative predictive value (NPV) and 0.97 positive predictive value (PPV), respectively.

Conclusions

We found satisfactory analytical performance of MAG-CLIA SARS-CoV-2 Ag, which could be used as surrogate of molecular testing for identifying high viral load samples. Broadening the reportable range of values may generate even better performance.

Published: March 2023

Objectives

Gladiolus psittacinus (GP) is an important medicinal plant in folk medicine where its corm is used for treatment of diabetes mellitus. Despite this, there is paucity of scientific information to justify its use as antidiabetic drug. Hence, this study was designed to explore antidiabetic, antihyperlipidemic and effects of aqueous extract of Gladiolus psittacinus (AGP) on hyperglycemia-associated oxidative stress in pancreas, kidney and liver of diabetic rats.

Methods

Diabetes mellitus (DM) was induced in rats using streptozotocin 50 mg/kg (i.p.). Normal and diabetic rats were treated orally with AGP once a day for 14 days. Antidiabetic effects were evaluated on body weight, fasting blood glucose concentration (FBGC), lipid profiles and serum chemistry. Also, protective effects of AGP were also determined on markers of oxidative stress, antioxidant enzymes and histopathology of pancreas, kidney and liver of diabetic rats.

Results

Treatment with AGP emanated to significant decrease of FBGC (552.67–157.33 mg/dL), increase in body weight (100.01–133.76 g) and positive modulation of lipid parameters in diabetic rats. The alteration in the contents of markers of liver and kidney function were significantly modulated in the diabetic rats upon treatment. Also, oxidative damage and antioxidant depletions in pancreas, kidney and liver were significantly mitigated in treated diabetic rats. Structural aberrations in the histopathology slides of pancreas, kidney and liver were improved upon treatment.

Conclusions

It can be concluded that AGP could be used in the treatment of diabetes mellitus and its related ailments, thereby justifying its usage in traditional medicine.

Authors: Mei Mengxue , Fang Ming , Mao Ye , Chen He , Huang Long
Published: March 2023

Previous studies suggest that baclofen may be useful in the treatment of intractable hiccup caused by chemotherapy. This study was aimed to assess the possible efficacy and safety of baclofen. In total, 65 patients with intractable hiccup caused by chemotherapy were screened. 45 patients with intractable hiccup caused by chemotherapy were finally recruited. Participants in the trial received 10 mg baclofen three times daily for 3 days. The primary outcome measure was cessation of hiccups. Secondary outcome measures included efficacy and adverse events. All 45 patients completed the study. Among them, 41 cases were cured (91.11%, 41/45), 4 cases were relieved (8.89%, 4/45), and the overall effective rate was 100% (45/45). Furthermore, the median remission time was 2(1, 9) times, the median cure time was 2(1, 9) times, the remission rate of one-time was 13.33% (6/45), the remission rate of two-time was 53.33% (24/45), and 2 cases (4.44%, 2/45) relapsed after drug withdrawal. No serious adverse events were documented. Only 1 case (2.22%) had grade 2 fatigue and 2 cases (4.44%) had grade 1 sleepiness. Baclofen is safe and effective in the treatment of intractable hiccup caused by chemotherapy of malignant tumor.

Published: March 2023

The mechanization of farming is currently the most pressing problem facing humanity and a burgeoning academic field. Over the last decade, there has been an explosion of Internet of Things (IoT) application growth in agriculture. Agricultural robotics is bringing about a new era of farming because they are growing more intelligent, recognizing causes of variation on the farm, consuming fewer resources, and optimizing their efficiency to more flexible jobs. The purpose of this article is to construct an IoT-Fog computing equipped robotic system for the categorization of weeds and soy plants during both the hazy season and the normal season. The used dataset in this article included four classes: soil, soybean, grass, and weeds. A two-dimensional Convolutional Neural Network (2D-CNN)-based deep learning (DL) approach was implemented for data image classification with dataset of height and width of 150 × 150 and of three channels. The overall proposed system is considered an IoT-connected robotic device that is capable of applying classification through the Internet-connected server. The reliability of the device is also enhanced as it is enabled with edge-based Fog computing. Hence, the proposed robotic system is capable of applying DL classification through IoT as well as Fog computing architecture. The analysis of the proposed system was conducted in steps including training and testing of CNN for classification, validation of normal images, validation of hazy images, application of dehazing technique, and at the end validation of dehazed images. The training and validation parameters ensure 97% accuracy in classifying weeds and crops in a hazy environment. Finally, it concludes that applying the dehazing technique before identifying soy crops in adverse weather will help achieve a higher classification score.

Published: March 2023

In this work, hydroxymethyl octadecyltrimethyl ammonium chloride (HM-OTAC) was obtained from the reaction between octadecyltrimethyl ammonium chloride (OTAC) and formaldehyde in different molar ratios. The effects of the reaction conditions (different molar ratios) on the properties of the product (surface tension, foaming, high temperature resistance, methanol resistance and salt resistance) were investigated. The results showed that the HM-OTAC produced under different molar ratios could lower the surface tension of water solutions more than the surfactant OTAC. The HM-OTAC (1:2) reduced the surface tension to 28.29 mN m−1. The HM-OTAC produced under other molar ratios gave higher interfacial tensions than HM-OTAC (1:2). With increasing surfactant concentration, the foam volume first increased and then gradually decreased. At a concentration of 0.3 wt.%, the highest foam volume (460 mL) was produced with HM-OTAC (1:3). Compared to OTAC, the foams produced by each HM-OTAC surfactant exhibited higher temperature stability. In the presence of 30 mL methanol, the initial foam volume of all HM-OTAC surfactants (0.3 wt.%) was generally higher than that of OTAC. With 300 mL HM-OTAC (1:4) solution, the highest foam volume of 20.2 mL could be produced. HM-OTAC (1:3) showed the highest salt resistance.

Published: March 2023

The serine-threonine protein phosphatase 2A (PP2A) is a heterotrimeric enzyme complex that plays a vital role in regulating male reproductive activities. However, as an essential member of the PP2A family, the physiological functions of PP2A regulatory subunit B55α (PPP2R2A) in testis remain inconclusive. Hu sheep are noted for their reproductive precocity and fertility, and are ideal models for the study of male reproductive physiology. Here, we analyzed the expression patterns of PPP2R2A in the male Hu sheep reproductive tract at different developmental stages and further investigated its role in testosterone secretion and its underlying mechanisms. In this study, we found that there were temporal and spatial differences in PPP2R2A protein expression in the testis and epididymis, especially the expression abundance in the testis at 8 months old (8M) was higher than that at 3 months old (3M). Interestingly, we observed that PPP2R2A interference reduced the testosterone levels in the cell culture medium, which is accompanied by a reduction in Leydig cell proliferation and an elevation in Leydig cell apoptosis. The level of reactive oxygen species in cells increased significantly, while the mitochondrial membrane potential (ΔΨm) decreased significantly after PPP2R2A deletion. Meanwhile, the mitochondrial mitotic protein DNM1L was significantly upregulated, while the mitochondrial fusion proteins MFN1/2 and OPA1 were significantly downregulated after PPP2R2A interference. Furthermore, PPP2R2A interference suppressed the AKT/mTOR signaling pathway. Taken together, our data indicated that PPP2R2A enhanced testosterone secretion, promoted cell proliferation, and inhibited cell apoptosis in vitro, all of which were associated with the AKT/mTOR signaling pathway.

To repair or not to repair cracked wood
Authors: Hubbe Martin A.
Published: March 2023

If only wood could be defect-free, then the minimum strength of solid-wood beams and other structures could be much higher. Structural failures could be avoided, and-or less material might be required in some applications. Cracks in wooden structures can be filled with adhesives or with thermoplastic composite material. But to approach the intended strength of defect-free wood, it is necessary to use other strategies such as glued rods and surface patches. The ultimate answer may lie in better species selection, tree breeding, forestry strategies, lumber cutting practices, and lumber drying practices to avoid cracks in the first place.

Published: March 2023

The patterns and mechanisms underlying the effects of different types of biochar on crop dry matter accumulation and uptake of major soil minerals are uncertain. This study demonstrated the positive effects of adding pyrochar (PC) and hydrochar (HC) to calcareous soils on nutrient uptake by maize seedlings and revealed the important role of mycorrhizal colonization. The effects depended on the type of biochar added and the type of nutrient evaluated. The dry weights of maize seedlings were higher in the HC and PC groups than in the control group, and the P accumulation was 17% higher than that of the control. Adding PC significantly increased Zn accumulation and the concentration and accumulation of Cu in maize seedlings, whereas adding HC increased the Fe concentration. Applying PC and HC also promoted mycorrhizal colonization of maize roots, and P, Zn, and Cu accumulations in the plant were positively correlated with the mycorrhizal colonization rate. This study found that applying PC and HC to calcareous soil at the tested application rate promotes the uptake of some mineral nutrients by maize at the seedling stage, and this effect was at least partially influenced by an increased mycorrhizal colonization rate in the plant root system.
Hindu and Classical Ancient virtues in a comparative perspective
Authors: Shokhin Vladimir
Published: March 2023

The author claims that Graeco-Roman, Hindu and Chinese catalogues of virtues have much more common with each other than what is permitted by contemporary agnosticism in cultural studies which has only the appearance of wisdom. As to the differences, they are connected with the soteriological intention behind the Hindu catalogues while the Greek (before Neoplatonism) and Chinese ones label the development of secular personal dignity and social responsibility. The author does not conceal his preferences as well while asserting that the quadrangle of cardinal virtues as developed in Platonism had evident advantages in consistency over its Aristotelean restructuring via the division of virtues into intellectual and moral ones. He also is sure that this quadrangle was immensely improved in its Latin version by Cicero and Apuleius by means of narrowing the “multi-seated” Greek concept of sophrosyne up to “single-seated” temperantia. The initial Christian receptions of Graeco-Roman cardinal virtues are also estimated, and an alternative of their inbuilding into one of three human vocations in accordance with three Jesus Christ’s ministries is offertd.

Philosophy of religion F. Schleiermacher in the works of representatives of the theological academies of the late 19th — early 20th century: the concept of religious experience
Authors: Koreneva Nadezhda
Published: March 2023

The concept of religious feeling in the beginning XX century Russian thinkers dealing with the philosophy of religion are increasingly becoming the focus of attention, but the meaning of this concept is often not explicated, which makes it necessary to study the sources of this concept, one of which (the most important) are the works of F. Schleiermacher. This article is devoted to the analysis of the perception of his concept of religious feeling in theological academies: spiritual and academic periodicals, individual works on the philosophy of religion and textbooks of basic theology (apologetics) are considered. Basically, Schleirmacher's ideas are criticized, there are several ways to understand the "religious feeling": a number of authors adhere to the position of G.V.F. Hegel, feeling is considered by them as something secondary to reason and will (V.D. Kudryavtsev-Platonov, Proto. T. Butkevich); the concept of religious feeling can also be understood in a negative way as the aestheticization of religion (N.M. Bogolyubov, D.S. Leonardov, etc.), but most often the concept of religious feeling by Schleiermacher is understood as psychologism, as the subjectivization of religion, excluding the concept of revelation (S.A. Ornatsky, F. Aleksinsky, etc.). Finally, representatives of theological academies, whose works were written already at the beginning of the XX century, share the point of view of V. Dilthey, giving a fundamentally new interpretation of the concept of religious feeling as a pre-rational unity of consciousness (S.S. Glagolev). Finally, the author of the article concludes about the philosophical productivity of the considered interpretations of the concept of "religious feeling", and also briefly characterizes its significance for the Russian philosophy of the period in question as a whole.
Presentational icon with a view of Likhvin Dobryi monastery: dating, typology, iconography, stylistic features
Authors: Golubev Valentin
Published: March 2023

The article is devoted to the “podnosnoy” with the view of the Likhvin Dobryi Monastery of Intercession of Theotokos near Kaluga from the collection of the Andrey Rublev Central Museum of Ancient Russian Culture and Art (CMAR): the dating of the monument is specified, its typology is determined, the iconography and style are characterized. Due to the information about chronology of construction transformations carried out in the monastery it is possible to date the icon with the time range of 1818-1832. The lower dating limit is based on the stylistic features of this icon are formed by influence of architectural drawing from 1818. The upper limit determined due to the typological characteristics of the icon as a gift (testimonial icon) for a special important person in memory of the solemn consecration of the renovated monastery ensemble in 1832. The typological characteristic of the monument as a special gift is supported by a number of iconographic and typological analogies. The iconographic program of the icon shows the principles of compositional constructing of "podnosnoy" (tray) and "razdatochnyy"(handout) icons: the pictorial surface is divided into two parts; at the bottom a panoramic view of the city or monastery placed, and at the top of it there are celestial patrons. Taking into account the administrative dependence of the Likhvin Dobryi Monastery from the Kaluga diocese and comparing the icon with a number of dated works close to it in style, it was possible to place them in the circle of works of the Kaluga icons and artistic context of Empire era. A number of these analogies constitutes a separate stylistic line of this regional artistic tradition: it is distinguished by delicate coloring, sentimentality and classical restraint.
The modal particularity of 4th mode in Byzantine chant over the centuries (12–19th cс.)
Authors: Starikova Irina , Tyurina Olga
Published: March 2023

The history of Byzantine chant goes back many centuries. The modal system of Octoechos, that regulates most of liturgical compositions, emerged even before the appearance of the musical notation in the chant books, and then continuously developed. Over the centuries, this octomodal system absorbed a lot of divergent influences, so Byzantine and post-Byzantine modes appear as a fusion of archaic, classical and modern features. After a detailed study of the modal content of the fourth authentic mode, the authors reconstruct its melodic image and its evolution from the classical Byzantine period to the samples of the later Greek tradition. The present study is based on different sticheras of the hebdomadal and annual liturgical circles taken from the middle-Byzantine Sticherarion of the 12th to the 14th century, from post-Byzantine versions of the Sticherarion by the 17th-century authors Chrysaphos the Younger and Germanos of New Patras, and from collections of selected chants: the Anastasimatarion of Chrysaphos the Younger (17th century), the Doxastaria of Iakovos the Protopsaltis and Petros Peloponnesios, the Anastasimatarion of Peter Peloponnesios (18th century). The middle Byzantine evidence points to the special place of the fourth authentic mode in the octomodal system, as possessing a peculiar modal content: while other authentic modes have a third-fifth structure of the main cadences, in the fourth authentic mode the main cadences are arranged in a second relation. This trait impacts also the melodic formulas of the chants. Over the centuries, this peculiar feature has been preserved in the mutual relationship of the main cadences of the fourth mode. Accordingly, the melismatic enrichment of older versions of Sticheraria took place, but the main characteristics of the mode remained unchanged, in spite of the addition of supplementary modal cadences. The modal particularity of the fourth authentic mode may be explained by the combination of several modal components: the archaic features, inherited from pre-octomodal forms, merged with later elements and were embedded into the classical modal system.

Impact of covered conductors on Ghana’s distribution network
Authors: Akoto Jemima
Published: March 2023

Electrical power outages experienced in the vegetation areas in Ghana are as a result of bare conductors coming in contact with grounded objects such as trees and tree branches. To curb this problem, the electricity company of Ghana has introduced into its overhead distribution networks the use of CC, covered conductors. These covered conductors unlike the traditional bare wire conductors are able to temporarily withstand phase-to-phase earth voltages. XLPE, Cross-Linked Polyethylene, HDPE, High Density Polyethylene covered conductors together with ABC, Aerial Bundled Conductors are considered. Limitations associated with these covered conductors, greatly relating to cost, reliability, supply quality and safety have been discussed in this paper.
The explaining of some paranormal bio-effects by a thermo-mechanic model of cell membrane’ ionic pump functioning

Published: March 2023

In the paper are explained some paranormal effects such as the biotherapy, the telekinesis, the “phantom leaf” effect and the electric field of the plant “phytologica electrica” by a thermo-mechanic model of cell membrane’ ionic pump functioning, which considers a thermo-mechanical effect of the ATP transforming energy in the ions transporting process, obtained by a particular configuration of some reticulate network micro-tubes ends and by the generating of 5÷20% holes into cytoplasm by the action of the ATP’s transforming energy but also by an ionizing radiation, generated particularly by intense vibration of electric charges, with high frequency, as in the case of the Kirlian effect.
HF Propagation during geomagnetic storms at a low latitude station
Authors: Olatunbosun LG , Olabode AO , Babinisi AB , Ariyibi EA
Published: March 2023

The variations in the ionosphere affect the radio wave propagation. These variations become more pronounced as a result of geomagnetic storms. The data from a Digitonide installed at Guam station (Lat. 13.62oN and Long. 144.86oE) during geomagnetic events was scaled for an ionogram, which shows the heights of different layers in the ionosphere at different frequencies. The ionogram was then analysed and interpreted. Results showed that virtual heights steadily increased as frequency increased. The splitting of waves into ordinary and extraordinary waves as they enter the ionosphere was an indication that waves divide on entering the ionosphere. The extraordinary was consistently higher than the ordinary wave. The highest frequency the ionosphere above the station could refract signal at 180o was 12.625 MHz. This is the frequency at which communication was to be made from one location to another location within the location of the station. Comparative results between the iongrams of disturbed and undisturbed ionosphere showed that geomagnetic storms lead to increased foF2, MUF values and NmF2. The results also revealed that the strength of the refracted signals were particularly good, strong enough to rebound from the earth and refract again.
Can the ball lightning be the manifestation of a micro black hole?
Authors: F Burov Vladimir , Sheleg Sergey V
Published: March 2023

The physical nature of the ball lightning (BL) is still the mystery regardless of several proposed theories. The hypothesis stating that the BL can represent the “micro black hole” (MBH), which, interacting with the terrestrial gravity force, generates the directed radiation, which allows it to “levitate”, deserves special interest. Having taken this possibility into account, the analysis had been held with regard to the ability of the MBH to generate electromagnetic radiation (ER) for “levitation”, with the BL weighing one gram as a basic point. Additionally, the duration of its potential lifecycle is evaluated. The performed calculations attest to the fact that the BL cannot represent the MBH.
Using the big solar furnace as an astronomical telescope
Authors: A Abdel Hadi Yasser , Sobirov Y , Makhmudov SSH
Published: March 2023

The effect of the total solar eclipse on the performance of the solar concentrator is studied on the Big Solar Furnace (BSF) in the Institute of Material Science Scientific-Production Association "Physics-Sun", Academy of Sciences of Uzbekistan at Parkent of Uzbekistan during the partial solar eclipse of August 1, 2008. It is found that the solar radiation decreased dramatically in the first half an hour from 500 W/m2 at 15:00 to a few Watts per squared meters at 15:35, while it began to increase gradually until reaching about 370 W/m2 at 17:08. The distribution of the heat in the focus of the BSF is tested by measuring the heating power of radiation concentrated by the furnace during that eclipse. Heat energy distribution contours are obtained in the mode of tracking the trajectory of the sun during the eclipse. The divergence of the focus during the eclipse of the BSF doesn't exist and the structure of the spot has no significant change. The possibility of using the Large Solar Furnace of megawatt power as an astronomical telescope is shown.
Revisiting the nature of dark sunspots: not magnetic, but thermal activity of the Sun
Authors: Kuzmich Soika Alexander
Published: March 2023

This article is a continuation of the works1-4 of the author, devoted to elucidating the physical nature of dark sunspots. It has been proven that the scientific paradigm of dark cold sunspots prevailing in solar physics is erroneous, since it contradicts the second law of thermodynamics. It has been proven that dark sunspots in the solar photosphere can only be hotter than the photosphere, and their visual darkness is of a non-thermal nature. Sunspots are the hottest areas of the Sun's surface, the temperature of which is ~ 6∙106 K, and they are the cause and sources of thermal energy of solar activity phenomena. The physical and empirical inconsistency of the concept of the magnetic activity of the Sun and the processes of magnetic reconnection in the solar atmosphere is proved. All unsolved problems of solar physics, including the heating of the corona, are due to the false paradigm of cold sunspots.

Perceptions of a – level physics students and teachers on the effectiveness of online physics teaching and learning
Authors: Matorevhu Alois
Published: March 2023

Compelling evidence why physics should be effectively taught at secondary school level, include its use in the universe to find solutions to daily life challenges. Physics education prepares secondary school graduates to proceed with the study and application of science to explore the universe, as well as being productive members of diverse socio – economic sectors of any nation. Understanding Physics and developing skills that allow students to be responsible citizens in promoting sustainable development depends on how physics education is taught. While interaction between classmates, and students and teachers is important, but with the advent of the COVID – 19 outbreak the learn from home policy which many countries adopted, suspended face – to – face learning, giving way to physics online learning as a combination of synchronous and asynchronous distance learning. This study sought to explore A – Level physics learners' and teachers’ perceptions on the effectiveness of online physics teaching and learning. Semi – structured interviews with purposive sampled A – Level physics learners (PLs) and physics teachers (PTs) were used to collect data. Findings from the study show that if online physics learning is to be successfully, then it should be implemented blended with face – to – face learning. However, ways to support those learners disadvantaged financially to afford data to remain internet connected, should be put into place so that every learners benefits. The study has shown that not all physics concepts can be taught effectively through online strategy, therefore physics syllabi should clearly spell out areas which can be taught online and those which are mandatory to be taught face – to – face.
‘I’m just imitating the idiot’

This study examines how exclusionary acts of status degradation are performed through embodied stances and pejorative category ascriptions in the midst of a situated game activity where two boys align in mockful stances and stylized enactments towards a targeted boy. Drawing on a multimodal interactional approach to stance and membership categorization combined with sociolinguistic work on indexicality and identity, it shows how the cumulative patterning of derogatory stances index a deviant gender identity for the targeted boy. While the target is repeatedly cast as ‘abnormal’ and an ‘outsider’ by attributing (non-)boyhood features as ‘incompetence’ and ‘cowardness’, the two boys’ elevate own positions and display shared commitments to themselves as ‘real (warrior) boys’.

O número de notificações de acidentes com animais peçonhentos aumentou no Brasil entre 2007 e 2017. Apesar dos acidentados terem sua rotina alterada, é notável que os animais peçonhentos sofrem preconceitos e são, geralmente, perseguidos e mortos – independentemente de sua importância ecológica e médica. Nessa perspectiva, o objetivo principal deste estudo foi diagnosticar a percepção de estudantes de uma escola estadual do Rio Grande do Norte sobre os animais peçonhentos, e analisá-la após uma atividade de sensibilização ambiental. De maneira geral, revelou-se que os conhecimentos dos estudantes sobre os animais peçonhentos eram mais associados ao senso comum, tendo em vista que essas noções apresentavam algumas deficiências conceituais. Após a atividade de sensibilização ambiental (palestra), foi notável a ampliação dos conhecimentos deles sobre o tema, inclusive sobre a prevenção e sobre os procedimentos cabíveis em casos de acidentes. As provas dessa ampliação de conhecimento, por exemplo, são as de que: 95% dos participantes conseguiram identificar o conceito científico de animais peçonhentos; 100% identificaram medidas preventivas de acidentes; e, 95% afirmaram, agora, saber realizar os primeiros socorros em casos de acidentes. Observou-se que a percepção conceitual dos discentes sobre a temática foi modificada após a atividade de sensibilização ambiental proposta por esta pesquisa, revelando a importância de uma atividade de educação ambiental após um estudo da percepção prévia.
¿Existe la violencia obstétrica?
Authors: Medina-Castellano Carmen
Published: March 2023

Objective: to stimulate reflection on the existence of practices that violate the rights of women in obstetric care by health professionals and the need to promote the development of legal norms aimed at preventing and punishing such behavior. Methods: a literature review and an examination of different international instruments and current Spanish regulations aimed at preventing violence against women were conducted. Results: there are few studies on care practices that can be classified as forms of obstetric violence. Nevertheless, the norms currently in force in Spain, as well as the health recommendations of national and international bodies, may initially be sufficient to promote women’s autonomy at the time of birth. Conclusion: crystallized institutional violence can be observed in obstetric care, which requires efforts aimed at promoting the values of respect for women’s rights among health professionals and making women aware of their decision-making power over the care they want.

Largamente utilizado em sistemas de produção de espécies produtoras de grãos em larga escala, o plantio direto tem sido adotado para a produção de hortaliças. No entanto, a elevada quantidade de possibilidades de combinações entre plantas de cobertura e sucessoras gera a demanda constante por estudos relacionados a essa temática. O objetivo do trabalho foi avaliar a utilização de diferentes espécies de gramíneas e leguminosas como possíveis culturas antecessoras ao plantio direto para a cultura da alface. Para tanto, foram avaliados seis tratamentos com plantas de cobertura: crotalária (Crotalaria juncea), feijão de guandu (Cajanus cajan), feijão-de-porco (Canavalia ensiformis), milheto (Pennisetum glaucum) e sorgo (Sorghum bicolor), além de um tratamento controle, com uso de vegetação espontânea. Verificou-se efeito positivo do cultivo da alface em sucessão ao sorgo, ao milheto e ao feijão-de-porco, enquanto que o seu cultivo em sucessão à crotalária e ao feijão guandu exibiu decréscimos da massa fresca, do número de folhas, do diâmetro da cabeça e da produtividade. Dessa forma, pode-se concluir que a formação de biomassa abundante sobre o solo, proporcionada pelas espécies de gramíneas P. glaucum e S. bicolor, melhora as condições de cultivo da alface em sistema de plantio direto, desde que realizado o correto manejo nutricional e hídrico da cultura. Em complemento, dentre as espécies leguminosas C. ensiformis proporciona o melhor desenvolvimento da cultura da alface, enquanto o cultivo de C. juncea deve ser evitado, a fim de não ocorrer perdas relativas no desenvolvimento da cultura de interesse.

O estudo teve como objetivo quantificar a variabilidade das características morfológicas dos frutos e das sementes da guavira [Campomanesia adamantium (Cambess.) O. Berg.], e estabelecer as estimativas de correlação entre essas características. Em uma amostra de 100 frutos foram determinados os diâmetros longitudinal e transversal; massas frescas do fruto, da casca e da polpa; número de sementes por fruto; teor de sólidos solúveis totais e teor de água da casca. Foram mensurados também o comprimento, a largura, a massa fresca e o teor de água de 100 sementes de guavira. Os dados foram analisados por meio de estatística descritiva, de ajuste de distribuições estatísticas e de análise de correlação de Spearman (rS). Os frutos de guavira possuem alta variabilidade nas massas frescas dos frutos, casca, polpa e sementes e no número de sementes por fruto, informações essas que podem ser exploradas nos programas de melhoramento genético e devem ser consideradas na formação de lotes homogêneos de sementes. Os frutos da guavira são constituídos de 60% de polpa, 36% de casca e 4% de semente. O maior rendimento de polpa do fruto pode ser otimizado com a seleção de frutos com maior diâmetro longitudinal e transversal e com maior massa devido ao alto grau de associação entre essas características e o rendimento de polpa. Os diâmetros longitudinal e transversal do fruto e a massa fresca do fruto são excelentes indicadores para a seleção de frutos com maior número de sementes, o que permite otimizar a propagação e a operacionalização do processo de produção de mudas de guavira nos viveiros.

O cenário do agronegócio brasileiro, destacado como promissor, intensifica a necessidade de ferramentas contábeis. Nesse sentido, este estudo analisou a contabilidade como um ferramental de apoio para a sucessão familiar em um condomínio rural. Para atender tal objetivo, buscou-se descrever o condomínio rural, averiguar a evolução dos indicadores de resultado, avaliar os custeios e financiamentos da atividade rural, identificar vantagens e desvantagens da migração para a personalidade jurídica, examinar a transferência do capital fundiário entre os condôminos e verificar a percepção dos pesquisados, condômino e contador, quanto à sucessão familiar rural e a contabilidade do condomínio pesquisado. O referencial abrangeu sucessão familiar e planejamentos sucessório e tributário. A metodologia é qualitativa, descritiva com procedimento técnico para o estudo de caso. Os dados foram documentais e baseados em entrevistas, analisados a partir de análise de conteúdo categorial que resultou quatro categorias, sendo: gestão na atividade rural, planejamento da sucessão familiar, contabilidade para atividade rural e dificuldades e desafios da atividade. Os resultados documentais mostraram que a contabilidade é um ferramental importante para a sucessão familiar do condomínio, visto que ela fornece informações necessárias à tomada de decisão e favorece a economia tributária. Concomitantemente, os resultados categoriais apontaram para a relevância da contabilidade no setor rural, sendo considerada um dos pilares do agronegócio. Diante disso, conclui-se que a contabilidade é essencial para tomada de decisão do condomínio familiar pesquisado, apresentando dados e informações úteis ao processo decisório.
