O impacto do conflito trabalho-família no processo decisório das mulheres: uma revisão da literatura
Authors: Macedo Luana Cachuite Mendes , Ribeiro Lívia Maria de Pádua
Published: May 2023

Esse trabalho apresenta uma revisão de literatura sobre o impacto do conflito trabalho-família no processo decisório das mulheres em seu ambiente de trabalho a partir dos estudos brasileiros expostos na base de dados SPELL e anais da ANPAD. Foram selecionados e analisados 11 artigos com o termo conflito trabalho-família, publicados entre 2011 e 2021 e com o termo processo decisório foram 22 artigos, avaliados sobre periódicos, área de conhecimento e período. Porém, na base de dados utilizados nesta pesquisa não foi possível identificar nenhum trabalho que relacionasse ambos os termos. Ao examinar apenas o termo conflito trabalho-família, nota-se que são estudos recentes, a partir de 2018, mesmo diante de poucos estudos, constatou-se que as mulheres são as mais impactadas pelo conflito. A falta de tempo é a condição que mais afeta os profissionais em geral. Enquanto o processo decisório apresenta-se um número considerável de artigos publicados, desde 2011. Contudo, a questão do gênero é escassa em publicações brasileiras, porém, em alguns casos, pode ser causador de conflitos durante a tomada de decisão. Logo, torna-se relevante as discussões deste estudo devido a uma carência de pesquisas quanto ao tema, em especial sobre o conflito trabalho-família.

La sociocritique à l’épreuve de l’histoire littéraire
Authors: Vaillant Alain
Published: May 2023

La sociocritique a parfois été l’objet d’un malentendu méthodologique. En France, accueillie – souvent avec enthousiasme – par des herméneutes rompus aux subtilités de la microlecture, la sociocritique a quelquefois semblé servir à redonner du sang neuf à l’exercice canonique de l’explication de texte, joyau de la pédagogie républicaine. Or Claude Duchet faisait tout le contraire et son ambition était infiniment plus grande. Même si, à l’époque où il a conçu la sociocritique, il ne pouvait que mettre le texte au coeur de son dispositif théorique, la visée était bien d’ouvrir la littérature à l’espace infini du hors-texte. Dans sa Première leçon du cours de poétique, Valéry voulait restituer à la littérature, conçue comme « acte de l’esprit », son « atmosphère d’indétermination plus ou moins sensible » ; c’est à un travail analogue que se livre Claude Duchet, sauf qu’il substitue à l’indétermination délicieusement narcissique de la pensée individuelle la poussée obscure et confuse de l’historicité sous le texte, autour du texte, hors du texte – et, bien sûr, in fine, dans le texte. Ce en quoi la sociocritique devient pleinement histoire ou, du moins, campe résolument à l’intersection de l’histoire et de la critique, grâce à l’inlassable activité et à la parole vive de Claude Duchet qui fut, pour deux générations de dix-neuviémistes, un modèle socratique et une figure tutélaire.

Many interesting phenomena, such as quantization of Landau levels and quantum Hall effect, can occur in an electronic system under a strong magnetic field. However, photons do not carry charge, and they do not have many properties induced by external magnetic fields, either. Recently, the pseudomagnetic field, an artificial synthetic gauge field, has attracted intense research interest in classical wave systems, in which the propagation of the wave can be manipulated like in a real magnetic field. The photonic crystal is an optical structure composed of periodic material distributions and provides a good platform for studying the control of electromagnetic waves. In this work, we construct a uniform pseudomagnetic field by introducing uniaxial linear gradient deformation of metallic rods in a two-dimensional photonic crystal. The strong pseudomagnetic field leads to the quantization of photonic Landau levels in photonic crystal. The sublattice polarization of n = 0 Landau level is also demonstrated in our simulations. Unlike the real magnetic field, the pseudomagnetic fields of photonic crystal is opposite in two inequivalent energy valleys, and the time-reversal symmetry of the system is not broken. Our designed gradient photonic crystals support the transport of edge state in the gap between n = 0 and n = ±1 Landau levels. The edge state can propagate unidirectionally when it is excited by a chiral source. When a gaussian beam impinges on the photonic crystal, the propagating paths of two splitting beams can be controlled, which gives rise to the bend of two beams. Two photonic crystals with opposite pseudomagnetic fields are assembled together, and the interesting phenomenon of “snake-state” can be obtained. Our proposal opens the way for designing information processing devices by manipulating electromagnetic waves.

As an important uranium alloy, U-Mo alloy has excellent mechanical properties, structural stability and thermal conductivity, which is an important nuclear reactor fuel and tank armor. However, there exists a serious of fundamental problems of U-Mo alloy which need solving for practical applications. U-Mo alloy is easily subjected to surface corrosion of small molecules including the H2, O2, H2O, and CO2. The hydrogen corrosion and oxidation will have significant influence on it. In order to further investigate the reaction mechanism, based on the density functional theory and the transition state algorithm, the first principles calculation of γ-U (100) with Mo atom doping and Mo coating is carried out.

Firstly, the minimum energy path of H2 molecule is calculated for the dissociation adsorption on Mo-U and 4Mo-U surface. Secondly, the transition states of H and O atoms are studied during surface diffusing between adjacent most stable adsorption sites. Thirdly, the bulk phase diffusion of H and O atoms are investigated and the relationship is analyzed between adsorption energy and adsorption height in the bulk phase diffusion.

The results show that when H2 molecule is adsorbed at the configuration of top horizontal position, the H atom needs to overcome a barrier to triggering off the H—H bond-broken and then is adsorbed on surface bridge site by the neighboring atoms. The energy barrier for H2 dissociation on 4Mo-U is higher than that of Mo-U. Meanwhile, the lower energy barrier is required for O atom to diffuse in Mo-U, so that it can be adsorbed, dissociated and diffused quickly, and then forming an oxidation film on the surface. Furthermore, both H and O atoms need to cross the energy barrier to diffuse into the body phase, forming chemical bonds with the atoms and staying in the body phase stably finally.

In this paper, we comprehensively analyze the dissociation and diffusion of the initial stage for hydrogen corrosion and oxidation on uranium-molybdenum alloy by theoretical studies. The results lay a foundation for theoretically exploring the surface corrosion mechanism of U-Mo alloy. Meanwhile, They provide theoretical support for investigating burn-in and corrosion of uranium-molybdenum alloy, predicting material properties under extreme and special environment, and providing a reference for further research on corrosion resistance of uranium-molybdenum alloy.

Acoustic waves can manipulate particles without contact or damage, and has received increasing attention due to their potential applications in various fields, such as cell sorting, organoid construction, and material assembly. In general, high-throughput manipulation of microparticles relies on a large number of active transducers and phase-shifting circuits to create standing wave patterns, thus significantly inducing system complexity. Recently, we realized the parallel manipulation of microparticles by using an acoustic field modulated by a one-dimensional phononic crystal plate. The concept is based on the fact that phononic crystal plate can resonantly excite the zero-order asymmetric (A0) Lamb wave, inducing highly localized periodic radiation force on the particles. In this paper, we further show that by using a two-dimensional phononic crystal plate (TDPCP), parallel manipulation of massive particles can be achieved only with a single transducer. The A0 Lamb wave can be excited by a TDPCP, forming a two-dimensional periodic localized field, and then particles can suffer negative vertical force and stable zero horizontal force, inducing two-dimensional periodic trapping on the surface of the plate. Combining a PZT source with a TDPCP consisting of a brass plate patterned with periodical brass stubs, we observe the capture and arrangement of glass microspheres, achieving two-dimensional arrangement manipulation of particles on the TDPCP. This system represents a significant advancement in developing high-throughput, rapid, and flexible devices for particles and cell manipulation.

Graphene-based van der Waals heterojunctions can not only modulate the electronic properties of graphene but also retain the superior properties of the original monolayer. In this paper, the structure, electrical contact types, electronic and optical properties of graphene/C3N van der Waals heterojunctions are systematically investigated based on first-principles calculations. We find that there is a p-type Schottky contact of only 0.039 eV in the graphene/C3N van der Waals heterojunctions in an equilibrium state. The external electric field can adjust the interface contact type, specifically, from p-type to n-type Schottky contact, or from p-type Schottky contact to Ohmic contact. The vertical strain not only opens a nonnegligible band gap of 360 meV on the Dirac cone of graphene in graphene/C3N van der Waals heterojunctions, but also modulates the band gap of C3N in the heterojunctions. Moreover, both the doping type and concentration of the carriers can be effectively tuned by the applied electric field and the vertical strain. The increase in carrier concentration is more pronounced by the applied electric field. Comparing with the pristine monolayer graphene and monolayer C3N, the optical response range and the light absorption rate of graphene /C3N van der Waals heterojunctions are enhanced. Main absorption peak in the spectrum reaches to 106 cm–1. These results not only provide valuable theoretical guidance for designing Schottky-based graphene/C3N van der Waals heterojunctions devices, but also further explore the potential applications of heterojunctions in optoelectronic nanodevices and field-effect transistor devices.

Polarized neutron scattering, as one of the experimental techniques of neutron scattering, is a powerful tool for exploring the microstructure of matter. In polarized neutron scattering experiments, magnetic field maintains and guides the neutron polarization, and determines the sample magnetic environment. For complex magnetic sample, it is often necessary to apply zero-field environment at the sample position, so that general polarization analysis becomes feasible. To achieve effective zero-field environment for polarized neutron experiment, carefully designed magnetic field is required.

In this work, we demonstrate a zero-field sample chamber designed for polarized neutron experiment by utilizing both permalloy material and high-TC superconducting films. This design adopts a simple and low-maintenance ‘deep-well’ shape to achieve effective shielding. The study uses finite element simulation method to analyze the effect of dimensions on the magnetic field shielding performance of the device of the model, including height, arm length, opening radius, and superconductor distance. At optimal dimensions, the designed zero field chamber achieves an internal magnetic field integral of 0.67 G·cm along the neutron path under the geomagnetic field condition. The maximum neutron depolarization for 0.4 nm neutrons is 0.76%, which sufficient for general polarization analysis application. The finite element method simulation results are examined by neutron Bloch equation dynamics simulations and in-lab measurement . Based on the established effective zero-field shielding design, we further discuss the relationship between magnetic field shielding and the dimensions of the device. The application of the device to spectrometers and the future improvement in the device structure are also discussed.

Authors: Pandey Poornima , Bhake Arvind
Published: May 2023

The cytodiagnosis of Warthin’s tumour by Fine Needle Aspiration Cytology (FNAC) in the submandibular salivary gland in literature is sparsely reported. Constituting an outnumbered portion of salivary gland neoplasms, it is a monomorphic adenoma that mainly arises in parotid gland. The occurrence of it in minor salivary gland and submandibular salivary gland is minuscule. Therefore, the confrontation of cytomorphological features of Warthin’s tumour poises the problem of interpretation. In spite of the fact that, Warthin’s tumour dispense as a clinically benign, slow growing and asymptomatic lesion with minimal rate of recurrence, nevertheless this entity is contemplated peculiar because of its unknown origin and cytomorphological appearance. The cytopathological smears prepared depict papillaroid sheets of oncocytoid cells which entails careful distinction for its diagnosis. The present article outlined such rare case of Warthin’s tumour for its cytomorphological character and its clinical finding for its medical rarity. Here by, authors describe a case of Warthin’s tumour of two years duration in a 44-year-old male patient in the right submandibular gland. The clinical examination had revealed it to be a mass of 4x4 cm lying just below the angle of mandible, with solid as well as cystic components. As a part of presurgical diagnosis the patient was referred for FNAC. The smears were prepared from both components of swelling and the peculiar case was pondered over for various concepts regarding its clinicopathological features with main emphasis on cytomorphology

Authors: Sa'd Rami
Published: May 2023

Storage of guava fruits by using refrigerators as post-harvest treatment is commercially acceptable but is expensive, especially in developing countries. So, the present investigation was carried out with the objective to compare the efficacy of 1-MCP and their most effective concentrations for the shelf-life enhancement of guava fruits without any deterioration in fruit quality in the winter season at both cold and room-temperature storage conditions. Horticultural mature guava fruits were treated with 150, 300, and 600 ppb, and then stored at room temperature at 21°C, RH 45%, or cold storage at 6°C, RH 85%. The Results showed that the highest concentration of 1-MCP (600ppb) significantly (P<0.05) preserved fruit firmness, and organoleptic quality attributes. In addition, the fruit weight loss, decay percentage, titratable acidity (TA), total soluble solids (TSS), and fruit color development were significantly preserved compared to other treatments under both cold and room storage conditions. Generally, 1-Methylcyclopropene (1-MCP) could maintain the quality of guava fruit combined with cold temperatures for 24 days. While 150 and 300 ppb 1-MCP preserved the quality of fruits for up to 20 days compared to untreated fruits for 16 days. Otherwise, treated fruits with 600ppb of 1-MCP kept at room storage temperature preserved fruits quality for up to 20 days compared with untreated fruits for up to 12 days stored at room storage condition. Hence, 1-MCP as post-harvest treatments preserved the overall quality parameters and enhanced the shelf life of guava fruit even after two weeks of storage at ambient temperature and three weeks after cold storage. Otherwise, 1-MCP could be an alternative to cold storage, as it is more economical than cold storage, especially in developing countries.

Authors: Sachitra Vilani , Silva Devni
Published: May 2023

Purpose: In the current context, toxic workplaces are increasingly popular within organizations which lead to an increase in exhaustion and work related stress. Low staff morale, high employee turnover, low productivity, and poor work quality are just a few effects of this type of toxic workplace environments. Due to such negativity placed upon wage employment, people who are struggling are looking for better means of employment such as self-employment. The primary purpose of this study is to evaluate how the transitions decision of self-employment over paid employment influences job satisfaction at the individual level.  

Design: A qualitative study was conducted using semi-structured interviews. 15 individuals who have transitioned to self-employment were chosen on the basis of purposive sampling. Under the 3 main categories of self-employment, wage employment as well as job satisfaction, key findings were gathered, and conclusions were drawn based on the insights received from the interviewees.

Findings: Findings of this study clearly show that individuals are struggling due to the degradation of wage employment and eventually self-employments do attain job satisfaction comparative to wage employment.

Implications: The findings further important to individuals who are struggling at their workplace but has not made up their minds to transition to self-employment hence contemplating, to easily make their decisions and to get rid of their toxic workplace. The study provides advisable guidance to the individuals contemplating to transition from wage employment to self-employment.

Future Research Suggestions: Conducting more interviews is necessary to draw better conclusions on the subject. The job satisfaction can be a subjective concept therefore, different individuals may hold different opinions which may contradict with each other, therefore is important to do more research on the subject to get wider insights.

Published: May 2023

Introduction: The novel corona virus (COVID-19), which began in Wuhan, China, in December 2019, has been declared pandemic by the World Health Organization (WHO) on 11th March 2021. Till now, even when nations are in race for developing vaccine against COVID-19, diagnosing the cases and isolating them still remain the only way to contain the disease spread. Hence, effective triage of the suspected COVID 19 patients, becomes an effective tool in preventing disease spread, especially in developing nations. Simple hematological parameters like leukocyte counts, platelet counts, hemoglobin and parameters derived from complete blood counts namely NLR, derived NLR, PLR and liver function tests can be studied and analysed to differentiate COVID 19 patients from other non-COVID 19 Severe Acute Respiratory Illness (SARI) patients. These are the investigations at first point of contact with the patient and are relatively cost effective, keeping in mind the population of developing nations.

Patients and Methods: Retrospective case control study conducted over a period of one month including 286 consecutive Severe Acute Respiratory Illness(SARI) patients admitted in a                  tertiary care hospital in Delhi. The patients were divided into COVID-19 positive and COVID-19 negative groups based on their results of reverse transcriptase-polymerase chain reaction (RT-PCR) for COVID-19. The demographic data, and routine hematological and biochemical parameters including derived parameters like Neutrophil lymphocyte ratio (NLR), derived NLR  ratio, Platelet lymphocyte ratio (PLR) and Prognostic nutrition index (PNI) were analyzed and compared between the two groups using SPSS version 23.0. A p value of <0.05 was considered significant.

Results: The COVID-19 positive patients had a significantly higher lymphocyte percentage (p value=0.017) and Serum Glutamate Pyruvate Transaminase(SGPT)( p value=0.033), and a significantly lower Absolute Neutrophil Count (ANC)( p value= 0.023), NLR(p value=0.033) and platelet count(p valu=0.001). No significant difference in other haematological and biochemical parameters was found.

Conclusion: NLR, platelet count, lymphocyte percentage and SGPT are the simple laboratory biomarkers of inflammation that can be utilized for screening and triage in COVID 19 disease with variable sensitivity and specificity.

Published: May 2023

Limestone soils are stressful for plant growth. Plant-associated ectomycorrhizal (ECM) fungi may promote plant growth under stressful conditions, yet available information on ECM fungi in limestone areas is scarce. We investigated the ECM fungal communities associated with dominant tree species in a subarctic limestone area. We aimed to determine whether the ECM species differed between calcareous and non-calcareous areas, and the distribution property common to ECM fungi in limestone areas. Morphological characterization and DNA sequencing of root tips identified 57 ECM taxa. The ECM fungal compositions in the calcareous area differed from those in the non-calcareous area, even when comparisons were made between fungi on the same tree species. Rather, when ECM species were grouped at the genus level, they tended to be dissimilar between calcareous areas and between non-calcareous areas. Especially, Tomentella spp. and Sebacina spp. tended to be present more frequently in calcareous areas, while Cenococcum geophilum and Russula spp. tended to be present more frequently in non-calcareous areas.

Place and Duration of Work: The study was carried out in the Department of Agricultural Microbiology, University of Agricultural Sciences, GKVK, Bangalore, India.

Methodology: A leaf disc bioassay was employed to assess the virulence of entomopathogenic fungal isolates isolated from 2 agro-climatic zones of Karnataka, India under In vitro conditions. The lethal concentration and lethal time were determined by obtaining the mortality data from various conidial concentrations and the data was analysed using Probit analysis. For molecular identification the fungal DNA was isolated through Cetyl trimethyl ammonium bromide (CTAB) extraction buffer, followed by purification through phenol/chloroform extraction and precipitation with isopropanol or ethanol, and the ITS regions of the 18S rDNA were amplificated using universal primers.

Results: Out of 81 fungal isolates, 16 (19.25%) showed insecticidal activity under in vitro conditions. The results of the in vitro studies revealed that two isolates, ENPF-8 and ENPF-58 had significantly higher mortality rates (93-95 %) against mites at a concentration of 1x108 conidia/ml after 9 days after treatment (DAT). The virulent fungal isolates were identified as Isaria fumosorosea (with accession no: MT997932) and Hirsutella thompsonii (MT997936) using the sequencing of the ITS region of the 18S rDNA gene. H. thompsonii (ENPF-58) was found to be more virulent against mites, with lower LC50 (7.6×105 conidia/ml) and LT50 (5.7, 5.89, and 5.99 days) values compared to the other EPF.

Conclusion: Based on results, it is evidenced that though all isolates caused mortality in the mite population but the percent mortality was varied. Based on these results, H. thompsonii (MT997935) and Isaria fumosorosea (MT997932) could be a promising biocontrol agent due to their high virulence against mites.

Institutional support measures are formulated to induce the agriculture of the nation and also improve the livelihood of the farming community. The study aims to develop a scale to measure the attitude of farmers towards institutional support measures to mitigate the climate change for sustainable livelihood of Cauvery delta zone farmers. Hundred possible statements were prepared to assess the farmer’s attitude towards climate change using the five-point continuum. Since the selected scale values should have equal appearing interval and distributed uniformly along the psychological continuum, it was necessary to form 10 compartments so as to select ten statements at one statement from each compartment. Based on the high S-value and low Q-value each statement was found and the final scale comprised of ten statements. The scale was developed using the equal appearing interval method, which comprises of 10 statements (six positive and four negative). It was found that nearly two third 63.66 per cent of the respondents had moderately favorable attitude towards institutional support measures followed by 19.34 per cent of respondents had less favorable attitude and only 17.00 per cent of respondents had high favourable attitude towards institutional support measures. Hence, medium to high level of favourable attitude towards the institutional support measures on climate change is giving hope for the extension professionals for improved and better implementation of suitable modification in climate change-based programmes to the farmers.

India's Organic Agriculture A Vision for a Healthy Country
Authors: Singh Sourabh
Published: May 2023

The two key elements of food quality and safety are receiving more and more attention from the general public. The inclusion of increased levels of conventionally grown food has pesticide residue, hormones, toxic metals, antibiotic residue, elevated nitrate, and genetically modified organisms. Farmed food has a significant negative impact on health. Additionally, foods cultivated traditionally are less nutrient-dense and contain fewer protective antioxidants. Due to its potential health advantages and rising food safety concerns, demand for foods cultivated organically has expanded over the past few decades. Organic food production is described as farming without using artificial pesticides, hormones, and antibiotics, as wellas artificial fertilizers and insecticides. A growing number of people are choosing to eatorganicfoods because of their advantages in terms of nutrition and health. Additionally, organic farming safeguards the environment and greater socioeconomic impact on a nation. India is a nation equippedwith native abilities and the growing possibility of organic agriculture. India, whichfor a variety of reasons lagged behind other countries in adopting organic farming, is now oneof the world's top producers of organic food, thanks to its rapid -growth in organic agriculture. Therefore, by ensuring sustainable development, organic farming has a big influence on a nation's health, like in India. We might conclude that encouraging organic farming is important given that India is presently the largest top producer of organic food. Farming there would eventually lead to the development of a politically, environmentally, and economically healthy country.

Improper disposal of solid waste is one of the main causes of environmental pollution. Converting solid waste into compost and using it as an organic fertilizer in agriculture are an effective waste management method. Quality of such fertilizer may affect both human and environmental health. Therefore, in this study, compost from segregated and unsegregated urban solid waste compost was analyzed for its physical-chemical, biochemical, biological characteristics and the results were compared with the standards. In this descriptive-analytical study, compost samples were collected throughout a 3-month period at intervals of 20 days (2 methods, S1-Segregated, S2-Unsegregated urban compost) for physio-chemical analysis. In the present study, physical parameters such as moisture content, temperature and bulk density were 23.65%, 31 (°C) and 1.01 (g/cm-3). Chemical parameters such as pH, EC, C/N ratio, organic carbon, Total Nitrogen, Phosphorus, Potassium, Ca, Mg, S, Fe, Mn, Cu, Zn, Ni, Pd and Cr content were 7.75, 1.12 (dS m-1), 17.78, 29.16, 1.64, 0.45, 1.11, 1.47, 0.74, 0.76%, 3529.11, 350.67, 41.11 and 118.07(mg kg-1), respectively. The heavy metal concentration viz., nickel, lead, chromium content were 12.75, 23.87 and 12.53 (mg kg-1), respectively. Heavy metals concentration was detected at all the decomposition stages of composting and were to found to be within the permissible limits of Ohai-EAP standards. From the results, it can be concluded that, segregated urban waste composting could produce acceptable quality of compost, which can be used as fertilizer or soil amendment.
