Por um sistema amazônico de educação escolar multilíngue
Authors: Gomes Antonio Almir Silva
Published: August 2023

A Amazônia dentre tantas outras formas de diversidade, é multilíngue em essência, seja em virtude das centenas de línguas indígenas, seja em virtude das línguas de imigrantes, ou mesmo em virtude dos contextos de fronteira, por onde circulam as línguas francesa, espanhola, como também, a considerar Gomes e Neris (2020), inúmeras outras. Essa diversidade materializada em distintas formas de multilinguismo precisa ser entendida do ponto de vista linguístico, como objeto de pesquisa, mas também reconhecida, valorizada e promovida pela sociedade como um todo. Nesse sentido, o objetivo do presente artigo incide sobre a necessidade de construção de políticas públicas com escopo no reconhecimento, na valorização e na promoção de nossa natureza multilíngue amazônica, tendo no sistema escolar local privilegiado.
The effect of hypertension on renal functions in patients with acute coronary syndrome
Authors: UYAN Umut
Published: August 2023

Objectives: In patients with acute coronary syndrome, age, ejection fraction, diabetes, hypertension, and chronic kidney disease (CKD) are regarded as independent risk factors for the development of acute kidney disease (ACD). This research evaluated the glomerular filtration rates (GFR) of acute coronary syndrome patient groups who were hypertensive and those who were not.
Methods: This retrospective analysis comprised 764 patients with acute coronary syndrome who had applied to our institution before coronary angiography. There were two groups created from these patients. In the first group, there were 383 hypertensive patients; in the second group, there were 381 non-hypertensive patients. To assess how well these patients' kidneys were functioning, GFR was determined and compared.
Results: The mean age of the two groups did not significantly differ from one another (p = 0.053). The standard lipid measures of total cholesterol, triglyceride, low-density lipoprotein-cholesterol, and high-density lipoprotein-cholesterol levels did not differ substantially between the two groups. The two groups had no discernible difference regarding high-sensitivity C-reactive protein, N-terminal fragment brain natriuretic peptides, creatinine, and thrombocyte levels. Systolic and diastolic blood pressure, as well as diabetes mellitus, were all considerably higher in the hypertensive patients’ group (p < 0.001). The GFR in hypertensive patients was substantially lower (64.83 ± 19.76 vs. 70.71 ± 19.19, p < 0.001)
Conclusions: Our research revealed a strong link between hypertension and diminished renal function. This leads us to believe that hypertension may be a separate risk factor for the decline in renal function in acute coronary syndrome patients.

Published: August 2023

Aim: With the increasing life expectancy, the elderly population is gradually increasing. Considering the difficulty in recognizing and treating mental disorders in the elderly, clinicians should be careful about risk factors. This study aimed to investigate the relationship of chronic diseases with depression and anxiety levels and to raise awareness for mental illnesses in this age group.
Material and Methods: This study was conducted with 100 patients over 65 years of age. Patients with a diagnosis of psychiatric illness and using psychotropic drugs for the last 6 months were not included in the study. After the sample of the study was formed, the sociodemographic data form prepared by the researchers and the Hospital Anxiety and Depression Scale were applied to the patients.
Results: Anxiety levels were found to be significantly higher in female patients (p=0.032). A positive correlation was found between age and depression levels (r=0.225, p=0.025). No statistically significant difference was found in anxiety and depression levels between the patient groups with and without chronic disease (p=0.122, and p=0.668, respectively).
Conclusion: Chronic diseases, duration of the disease, and use of medication were not found to be associated with anxiety and depression levels, while anxiety levels were found to be higher in female patients, and also a significant positive correlation was found between age and depression levels. Mental disorders are a subject that needs to be examined in detail in elderly patients. The mental illnesses of elderly patients should not be ignored and should always be considered by clinicians.
Absolutnie wolny? Wolność człowieka w filozofii Giovanniego Pico Della Mirandoli
Authors: Nowakowski Dawid
Published: August 2023

Pico was generally perceived as a representative of the Pelagian heresy and a supporter of absolute freedom of man. However, more detailed analysis of his works reveals that in his views he was much more traditional than it used to be judged. Although Pico does not negate human freedom, he has consistently stressed the necessity of grace in salvation. So, in the question of free will Pico represents traditional post-Augustinian school and advocates, also present at the Thomas’, graduated concept of grace.

Background: Brewers spent grains (BSG), may offer a suitable cheap replacer for traditional feedstuffs. The present study investigated the effect of dietary substitution of wheat bran with BSG on performances and production economics of crossbred grower pigs . Methods: The current study was conducted on sixty crossbred pigs (28 male + 32 female) that were randomly divided into four groups and allotted to dietary treatment replacement by 0% (T0), 25% (T1), 50% (T2) and 100% (T3) dried BSG against conventional wheat bran in pig ration. Results: Results indicated significant (P less than 0.05) improvement in the total body weight gain and average daily gain (ADG) in both male and female crossbred pigs in groups T0, T1 and T2 when compared against T3. The performances of the both female and male pigs were significantly (P less than 0.05) lower when dietary levels of BSG were increased up to 100 % (T3). Group T3 had significantly (P less than 0.01) lower carcass traits as compared to the other groups. The feed cost/kg live weight gain in T2 was significantly (P less than 0.05) lower than the control group in both the sexes. In conclusion, crossbred pigs can tolerate up to 50% substitution of wheat bran with BSG and is cost-effective.

Published: August 2023

Background: Phosphatase producing bacteria (PPB) plays a major role in mineralising organic P into inorganic form. Though application of bacterial biofertilizers are practiced in agriculture, their application is very limited in aquaculture. Method: The PPB isolates were screened and isolated from rhizospheric sediment of mangrove, Avicennia marina of Ennore creek, Tamil Nadu. Their P transformation potential and the possibilities of their application in aquaculture to mineralise organic P to inorganic P were studied. Result: Twenty PPB isolates were screened in the study site and their Alkaline Phosphatase (ALP) activity was in the range of 13.6-20.4 µmol.ml-1.hr-1. Out of this, five Bacillus sp isolates were selected to assess their P transformation potential at various salinity. The P mobilizing potential of these isolates were compared with the commercial PPB following a microcosm study for a period of 14 days. During the study period, there is a significant increase in phosphorus in water as well as ALP activity and available phosphorus concentrations in sediments were observed between control and treatment tanks. Among the treatment groups, B. subtilis treatment tanks showed maximum P in water ie. 1.60mg.L-1, followed by B. altitudinis –1.49mg.L-1; B. pumilus –1.47mg.L-1; the soil ALP activity was in the order of commercial P products greater than B. pumilus greater than B. subtilis greater than B. paramycoides greater than B. altitudinis greater than B. aryabhattai. In terms of available phosphorus content in sediments on 14th day, there is no significant difference observed between B. pumilus and commercial product with respect to available P content of sediment.

POLICY AND GOVERNMENTALITY OF EARLY CHILDHOOD EDUCATION AND CARE IN ENGLAND
Authors: Mikuska Eva
Published: August 2023

This paper provides an overview and investigates the English Early Childhood Education and Care (ECEC) policy landscape. It introduces the political and ECEC policy history, and the development of the statutory Early Years Foundation Stage (EYFS) (DfE, 2021) framework, whose publication in 2008 was a significant milestone in ECEC in England. Twenty-two nursery workers from a variety of nursery settings were interviewed to learn what they think, know, and how this policy influences their professional practices. Foucault’s (1988) and Dean’s (1999) idea of ‘governmentality’ was used to analyze the data, as governmentality offers a way to create critical analyses of the ECEC policy that affects young children. The analysis recognizes the nursery worker's strong and often stressful relationship with government policy and highlights how policy documents mandated their work. The study also reveals that despite government regulations and guidance, most of the participants decide to continue with their professional development and enrol to study for a higher education degree.
ULOGA FIZIČKOG VASPITANJA U PREVENCIJI VRŠNJAŠKOG NASILJA U ŠKOLAMA
Authors: Turudić Jovana
Published: August 2023

U radu je analizirana uloga fizičkog vaspitanja u prevenciji vršnjačkog nasilja u školama. Vršnjačko nasilje kao veoma aktuelan i sveprožimajući društveni problem predstavlja svaku namernu, ponavljanu, neizazvanu negativnu ili verbalnu akciju koja ima neprijateljske namere, uznemiruje žrtvu, nanosi joj bol i stres. Kroz prizmu istraživanja koja se bave vršnjačkim nasiljem uočava se alarmantna situacija i potreba da se traga za efektivnijim merama prevencije navedenog društvenog fenomena. U borbi protiv vršnjačkog nasilja uviđa se uloga škole koja kao institucija može planski, organizovano i sistematski delovati u pravcu redukcije nasilja među svojim učenicima. Potencijale u redukovanju agresivnih tendencija ponašanja učenika pronalazimo u nastavnom predmetu fizičko vaspitanje. Čini se da časovi fizičkog vaspitanja mogu predstavljati prostor za sticanje osnovnih humanističkih vrednosti, za stvaranje nenasilne komunikacije i dobrih međuljudskih odnosa. Ističe se vaspitna uloga fizičkog vaspitanja čiji je cilj socio-emocionalni razvoj učenika, učenje nenasilnom rešavanju konflikata, poštovanju, strpljenju, empatiji, prihvatanju, altruizmu i razvoju timskog duha. Pored teorijske perspektive navedenih etičkih principa koji su inkorporirani u okviru kurikuluma fizičkog vaspitanja, neophodna je njihova empirijska provera kako bi se uticalo na smanjenje vršnjačkog nasilja u školama. Buduća istraživanja bi trebala da budu orijentisana ka ispitivanju preventivnih strategija vršnjačkog nasilja u školama, zatim empirijskog utvrđivanja trenutnog stanja po pitanju vršnjačkog nasilja u školama kao i detaljnija analiza povezanosti fizičkog vaspitanja sa vršnjačkim nasiljem.
Representação, consenso e a institucionalização excludente do conhecimento
Authors: Galbiati Lígia Amoroso , Santos Leticia Costa de Oliveira , Weins Niklas Werner
Published: August 2023

Questões climáticas e da biodiversidade têm mobilizado um corpo científico e institucional de conhecimento ambiental. Ambos, o Painel Intergovernamental sobre Mudanças Climáticas (IPCC) e a Plataforma Intergovernamental sobre Biodiversidade e Serviços Ecossistêmicos (IPBES), embora venham reconhecendo a importância de diálogos interdisciplinares e abertos para a participação diversa - como em relação a gênero - foram desenhados como painéis neutros de experts. A configuração desses espaços dificulta a representatividade, inclusão e efetiva participação de diferentes interesses e visões nos espaços decisórios. Destacamos a importância de questionar essa neutralidade e discutir relações de poder que permeiam a questão ambiental e os campos das ciências, mediante perspectivas da Ciência, Tecnologia e Sociedade (CTS) e da Ecologia Política. O objetivo é avaliar a inclusão de gênero no âmbito dos painéis, analisando semelhanças e diferenças, a partir dos Estudos de Gênero-CTS e Ecologia Política Feminista (EPF). A participação de mulheres é analisada quantitativa e qualitativamente em relação à composição dos painéis, seu posicionamento nas estruturas hierárquicas e políticas específicas para equidade de gênero. Também são observadas as relações desiguais entre membras do Norte e Sul Global. Destacam-se limitações da participação e imposição de consensos, desvalorização e instrumentalização de saberes, e limitações do desenho dos painéis como ferramentas de tutela ou promoção da autonomia. Espera-se um avanço na identificação de sobreposições e complementaridades entre EPF e Estudo de Gênero em CTS, destacando que as perspectivas feministas viabilizam outros enquadramentos de problemas, que superem a visão essencialista do outro e reconhecendo possibilidades para além do determinismo tecnocientífico.

Authors: Redemptus  , Weraman Pius , Umbu Roga Andreas
Published: August 2023

The concept of healthy-sick is no longer only related to the bio-psycho-social-spiritual aspects but also includes the physical and mental aspects. Chronic disease is a long-term and often incurable condition that requires continued management. Medical care, such as medication and surgery, is vital in managing chronic diseases. Non-medical treatments, such as positive thinking, a healthy diet, and fasting, can also significantly impact managing chronic diseases. Writing this article uses a library study or literature review. A holistic approach to health care can improve patient outcomes by improving physical and mental health, promoting better care coordination and communication, improving self-management skills, addressing psychosocial and spiritual needs, and providing patient-centric care.

Authors: Ayomi Mina Blandina
Published: August 2023

Background: Covid-19 vaccination among health students is an example of a social change agent or role model. Health students must be certain and able to use their knowledge. As a result, it is vital to investigate the likelihood of health students receiving Covid-19 immunization as a form of government support for the health program from the Republic of Indonesia. Objectives: To find out the certainty of health students to receive the Covid-19 vaccination in Jayapura City in 2022. Methods: A descriptive survey was carried out to perform quantitative research at Cenderawasih University in Jayapura City in August 2022. A total of 270 samples were collected using the probability sampling method. The instrument utilized was a questionnaire containing questions concerning health students' opinions about adopting the Covid-19 immunization, which was delivered via Google form. The data was edited, coded, entered, and tabulated before being presented in tabular form and narrated. SPSS was used to perform a univariate analysis of the data. Results: There were 190 respondents (70.4%) who were confident in receiving the Covid-19 vaccination, whereas there were 80 respondents (29.6%) who were unsure. Fear of adverse effects such as fever and pain was the most common reason for being unsure about the Covid-19 vaccine, cited by 56 respondents (97.5%), while comorbidity was cited by only two respondents (2.5%). Conclusions: There are still health students who are not sure about the Covid-19 vaccination. Health students need KIE (communication, information, and education) among health students regarding the necessity of the Covid-19 vaccine.

Authors: Rahadian Angga Sisca , Astuti Yuly
Published: August 2023

Background: Exclusive breastfeeding has an important role in preventing stunting among children due to chronic malnutrition. According to Indonesia Health Profile 2020, approximately 33.9% of children under six months were not exclusively breastfed. One of the challenges to achieving successful exclusive breastfeeding comes from socio-cultural aspects. Method: This mixed-methods study examined the socio-cultural context of barriers to exclusive breastfeeding among mothers. For a cross-sectional study in Karanganyar District, Central Java Province, a total of 706 participating mothers with children aged between 6–59 months were interviewed using a structured questionnaire in 2021. In addition, in-depth interviews with mothers were conducted to enrich the findings related to the obstacles in giving exclusive breastfeeding. Result: The binary logistic regression found that male children (AOR= 1.64, 95%CI (1.06, 2.56), children living in low-income households (AOR= 2.48, 1.25, 4.92), children with low-educated mothers (AOR= 8.84, 95%CI (3.83, 20.36), children with working mothers (AOR= 6.45, 95%CI (3.79, 10.98), children with pre lacteal feeding (AOR= 5.67, 95%CI (2.33, 13.75) were more likely to have nonexclusive breastfeeding. This study also revealed that 36,1% of mothers in Karanganyar District gave honey as pre-lacteal feeding to the newborn, which hindered exclusive breastfeeding practices. The qualitative approach also confirms this finding. Conclusion: Therefore, it is important to strengthen health promotion programs related to exclusive breastfeeding to mothers and the family through the life cycle approach based on the local context.

Authors:   Instituto de Geografía, Universidad Nacional Autónoma de México, Méndez-Astudillo Jorge
Published: August 2023

PM10 and PM2.5 concentrations are regularly monitored because they cause adverse effects on human health. The concentrations of PM10 and PM2.5 vary within a city due to land use, the amount of traffic, and pollution sources. As the COVID-19 pandemic spread around the world, lockdowns were enacted to stop the spread of the virus. These lockdowns meant reduced mobility and the halt of certain economic activities which had an impact on air pollution sources. In this paper, we assess the effect of the lockdown enacted in April-May 2020 in the Mexico City Metropolitan Area on PM10 and PM2.5 concentrations, using statistical analysis tools. MODIS-derived aerosol optical depth is used to assess the change of aerosols spatial distribution during the lockdown. Furthermore, a Mann-Whitney test is applied to PM10 and PM2.5 data from ground-based monitoring stations to evaluate the effects of lockdown. A general reduction of 20 % of PM10 and 10 % in PM2.5 was found. Overall, a 15 % reduction in particulate matter was found in Mexico City due to lockdown.

Light Dispersion in Gravitational Field
Authors: Zhu Yin
Published: August 2023

In any region of a space, the gravitational field cannot be eliminated. The speed of light in a vacuum has never been observed and cannot be observed with current technology. Till now, only the speed of light in a gravitational field has been observed. It results in that all the observed speed of light are always being varied by the gravity. Here, it is presented that light could be dispersion in a gravitational field analogous to the dispersion of light in the Newtonian prism experiment. The relativistic mass density on the surface of a neutron star is on the level of 1017kg/m3 while on the surface of the Earth is only 10-7kg/m3, the effect of the gravitational field acting on the speed of light by a neutron star is much larger than that by the Earth. Therefore, the dispersion of light in strong gravitational field could be generally observed from the image of a star and it should have been observed through the double-image gravitational lensing and the spectroscopic binary system. And, it should affect the observed numbers, spectrogram, size and distance of the celestial objects.

Published: August 2023

This study chose the indoor soil column test as the main method and the field test as the validation test to investigate the effects of various straw mulching techniques (surface, deep and straw mulching + deep burial) on evaporation and salt dynamics in saline soils. The results showed that straw mulching treatment could effectively reduce soil water evaporation, promote desalination in the stage of leaching infiltration and alleviate salt return in the stage of water evaporation, and the effect of straw mulching + deep burial treatment was better than that of single-layer straw mulching treatment. The indoor soil column test showed that S2D1 treatment (a 2:1 ratio of soil surface cover to the amount of straw buried 40cm below the soil surface) had the best effect on the suppression of soil moisture evaporation, and the cumulative evaporation of soil moisture was reduced by 65.85% compared with that of the CK, and the rate of salinity return in the evaporation stage was effectively reduced by 92.04% compared with that of the CK. In addition, there is a significant positive correlation between cumulative evaporation of soil moisture and cumulative soil salinity, which implies that cumulative soil salinity increases with cu-mulative evaporation of soil moisture. The results of the field experiment were consistent with the soil column test, and the S2D1 treatment was able to maintain high soil moisture content in all soil layers in all periods of the experiment and kept soil salinity in the 0-40 cm soil layer at a low level. However, in the 40-80 cm soil layer, the soil salinity suppression effect of DB treatment (straw buried at 40 cm below soil surface) was the best. So in summary, the S2D1 treatment had the best salinity and evapo-transpiration suppression effect in saline soils. This study is of great significance for the resource uti-lization of straw waste, improvement of water utilization and efficiency, and soil salinization manage-ment.

Plant-microbial interactions are very crucial for the terrestrial ecosystem. At the rhizospheric, phyllospheric and endospheric regions, these interactions occur through different signalling pathways and play a pivotal role as they strengthen the plant defence mechanism against pathogen attacks and other stresses. A better knowledge of these relationships will help to develop novel solutions for sustainable agriculture and safeguarding the global food supply in the context of climate change and mounting environmental concerns. This chapter emphasises the role of the microbiome in providing resistance to plants against various environmental stresses and aiding in their improved adaption. This chapter also underscores the impact of the microbiome in providing resilience to plants under changing climatic scenarios.
Meson-Exchange Currents in Quasielastic Electron Scattering in a Generalized Superscaling Approach

Published: August 2023

We present a model that incorporates the effect of two-body currents in quasielastic electron-nucleus scattering within the framework of a consistent superscaling formalism. This is achieved by defining an averaged single-nucleon hadronic tensor based on the 1p1h matrix element of the one-body current plus meson-exchange currents (MEC). The consistent treatment of one- and two-body currents in our model enables the calculation of exchange current effects in the kinematical region where the Fermi gas response is zero, but not the scaling function. The effect of MEC is consistently taken into account when extracting the phenomenological scaling function from electron scattering data. With this model, we investigate the effect of MEC on the response functions taking into account the effective mass of the nucleon, and examine the consequences it has on the inclusive (e,e′) cross section. We find that 1p1h MEC deplete the quasielastic transverse response, while they not alter significantly the scaling behavior of (e,e′) data.

AgW materials exhibit excellent properties and are widely used as contact materials in low- and medium-voltage switches. In this study, a pre-sintering and infiltration method was employed to pre-sinter W powder with Cu, Ni, and (Cu+Ni) addition in the low temperature range of 950–1050 °C. The low-temperature sintering behaviours of W skeletons with different additives were investigated. Subsequently, AgW70, AgW75, AgW80, and AgW85 materials were prepared through infiltration at 1050 °C. The microstructure morphology and physical properties of high-W contact materials were investigated using a metallographic microscope and scanning electron microscope. The mechanism of low-temperature sintering-infiltration of high-W contact materials was elucidated. The results indicated that pure W and 1% Cu-added W skeletons experience minimal linear shrinkage within the temperature range of 950–1050 °C. The linear shrinkage curves of W skeletons with different additives coincided under the conditions of 950–1000 °C/90 min. At 1050 °C, after sintering for 150 min, the particle boundaries in the W skeleton were fully spheroidised, with a dihedral angle of 120°. At 1050 °C and after 150 min of infiltration, cross-sectional micrographs of the AgW material revealed the presence of irregular Ni layers, where Ni spatially enveloped/encapsulated Ag. With an increase in the W content, the electrical conductivity and relative density of AgW(70–85) materials decreased, whereas the hardness of the materials increased.

: The silicon single crystals for semiconductor application is usually grown by Czochralski (CZ) method. This paper researches 300mm silicon Czochralski (CZ) crystal growth with CUSP magnetic field for IGBTs substrate application. The different positions of Zero-Gauss plane (ZGP) under CUSP magnetic field are simulated and compared to numerical analysis, investigated melt convection, melt flow velocity near to quartz crucible wall, diffusion boundary layer and effect of initial oxygen concentration in the silicon crystal, and the shape of solid/liquid interface was discussed. The results show that the change of the ZGP of the CMF mainly affects the convection in the melt, which leads to the difference of the thickness of the boundary layer near to the wall of the quartz crucible, and was found to be the key to reduce the oxygen dissolution from the crucible wall and oxygen diffuse into the crystal, along with the differences in the shape of the crystal-melt interface. In addition, we have carried out actual industrial single crystal production under the three configurations. The results show that the experimental data of oxygen content and shape of the crystal-melt interfaces in silicon crystal are consistent with the numerical results.

Over the past decade, plasma waste treatment has become a more prominent technology due to increasing problems with waste disposal and realizing opportunities to generate valuable co-products. Plasma waste treatment extensively uses atmospheric pressure (RF) inductive coupled plasma (ICP) torches. In situ Optical Emission Spectroscopy (OES) is used to evaluate the developed RF ICP torch for Municipal Solid Waste (MSW) treatment and ascertain the plasma parameters to understand the physical mechanism involved. The argon plasma jet's electron temperature and plasma density outside the torch chamber are calculated using the Boltzmann plot and Stark broadening at different gas flow rates, and RF power. The expected electron temperature and plasma density behaviour were observed at a low gas flow rate. The electron temperature decreases with the RF power from 8089 K to 6097 K as demand for increasing the plasma density. An energy loss mechanism was revealed while raising the gas flow rate, as the electron temperature increases with RF power from 5750 K to 6221 K, and the plasma density decreases. This behaviour is due to the anomalous skin effect. Detecting and avoiding this phenomenon is essential as it negatively affects torch energy efficiency and waste treatment.
