Authors: Steffanello Cocco Junior 
Published: December 2024

Os conflitos atuais promovem inúmeras consequências para o mercado mundial. Os impactos nas principais moedas comerciais são muito recorrentes, o que acaba impactando fortemente as empresas, tanto nacionais como internacionais. No que tange ao contexto brasileiro, várias organizações sentiram os impactos negativos causados por fatores do ambiente externo como, por exemplo, conflitos entre países e instabilidade política, conforme o Sebrae (2022). Com isso, nas empresas resiste a dificuldade em criar um ambiente saudável e produtivo para os colaboradores em que eles possam desenvolver suas tarefas de forma satisfatória, correspondendo aos objetivos propostos pela liderança. Ter uma equipe de colaboradores engajada faz com que haja um melhor desenvolvimento em relação às tarefas propostas, gerando uma satisfação maior para seus líderes e, consequentemente, aumentando seus ganhos como um todo. A conceituação de engajamento no trabalho é atribuída a Kahn (1990), ele visualizou que esse fenômeno ocorre em ambientes de trabalho, entre membros organizacionais, quando estes se expressam de forma cognitiva, emocional, mental e fisicamente. Pessoas engajadas voltam mais esforços para as suas atividades. Para isso, é necessário o conhecimento de técnicas, abordagens e metodologias, por parte dos gestores, relacionadas ao engajamento dos colaboradores no contexto empresarial. Tendo em vista o exposto, o presente trabalho tem como objetivo elucidar a importância da aplicação de técnicas de engajamento de colaboradores nas empresas, independente do ramo e método de quantificar o nível de engajamento dos trabalhadores. A pesquisa trouxe ferramentas das quais podem ser aplicadas no cotidiano de uma equipe, suas vantagens para o grupo em si e para a empresa. O método utilizado trata-se da aplicação de uma ferramenta desenvolvida pela pesquisadora Siqueira (2014), a escala de engajamento no trabalho (EEGT), aplicada em uma empresa de logística terrestre. Após a aplicação da escala, realizou-se a análise dos resultados obtidos a partir das notas atribuídas pelos colaboradores aos itens propostos, de acordo com a operacionalização da ferramenta, ranqueando seu engajamento com a empresa. Os resultados trouxeram um indicativo de baixo engajamento na empresa estudada, sendo um escore de 2,84. De acordo com as dimensões abordadas, o nível de vigor considera-se baixo, pois seu escore é de 2,76, assim como o nível de absorção, que também é baixo, com escore de 2,92. Ainda se observou que, a partir das respostas obtidas nas três perguntas realizadas, os respondentes citam que existem poucas práticas que promovem o engajamento na empresa e deve-se desenvolver recursos para melhorar esse quesito, como o aprimoramento da cultura empresarial.

Authors: De Almeida Reis Gustavo 
Published: December 2024

Resumo: O debate sobre questões raciais no Brasil perpassa a sua história. No entanto, a partir do último quarto do século XIX com o fim da escravidão, os problemas se colocaram de uma maneira qualitativamente diferente. Diversos atores sociais tentaram resolver, ao longo do século XX, questões fundamentais que tocavam o problema da integração racial no Brasil e o Partido Comunista do Brasil (PCB), foi um desses atores. O presente artigo objetiva discutir as contribuições de dois teóricos importantes do pensamento marxista brasileiro, ambos ligados ao PCB, sobre as questões raciais: Édison Carneiro (1912-1972) e Clóvis Moura (1925-2003). Pretende-se, com isso, comparar as intervenções teóricas de ambos os autores com as contribuições e decisões do partido sobre tais questões, medindo-as em seus graus de independência e originalidade em relação à linha partidária.

Published: December 2024

Abstract

In recent times, electric vehicles (EVs) have experienced battery pack failures dueto various factors such as short circuits, thermal imbalances, fires, and explosions.This research paper employs a machine-learning approach to estimate lithium-ion batteries safe operating area (SOA). It explores the factors that influencebattery safety levels and discusses the safe operating area for charging and dis-charging based on real-time data. The SOA concept is a critical consideration inthe design, operation, and management of EV batteries, as it defines the limitswithin which the battery can operate safely without compromising performanceor endangering the vehicle. The significance of SOA analysis for EV batteriesand its implications on battery design, thermal management, charging strate-gies, and overall vehicle safety. This paper specifically addresses the estimationof the safe operation of a battery using ML in relation to voltage and temper-ature with respect to time. It emphasises the importance of understanding theinterplay between these parameters to establish safe operational limits.

Published: December 2024

Abstract

Beryllium-free Cu alloys, such as Copper-Nickel-Silicon-Chromium (Cu-Ni-Si-Cr) alloys, are utilised extensively in diverse sectors such as the electrical, electronics, instrument, metallurgy, aerospace, automotive, petrochemical, machinery manufacturing, and die and mould-making industries. Due to their high strength and hardness, these alloys are often fabricated into components for the above-mentioned industries using unconventional machining techniques like electrical discharge machining (EDM). EDM is particularly advantageous in industrial applications where precisely controlled random surface textures on these alloys are required. However, despite the industrial significance, experimental investigations into the EDM process of Cu-Ni-Si-Cr alloys are scarce. Therefore, the current work aims to address this research gap by conducting an experimental investigation of the random surfaces generated on Cu-Ni-Si-Cr alloy components after the die-sinking EDM process, utilising a comprehensive three-dimensional (3D) surface topography analysis. This work investigates the effects of input factors such as the electrode material, dielectric fluid material, flushing condition, and current on nearly all relevant areal texture (3D) parameters. The regression analyses reveal that current is the most significant input parameter for most areal texture parameters, followed by dielectric fluid and electrode materials. The flushing condition had minimal effect, marking a new direction for future research. The significance of each areal texture parameter was discussed from an application point of view, highlighting the potential impact of the findings.

Published: December 2024

Abstract

Background
Upper tract urothelial carcinoma (UTUC) is a rare among all urologic cancers. Both UTUC and renal cell carcinoma (RCC) can present as a solid mass renal mass on imaging. Based upon current guidelines, small parenchymal-based renal mass suspected to be RCC may be monitored, thermally ablated, or surgically removed. In contrast, cryoablation is not considered a standard of care for a UTUC. Our case is of a renal parenchymal-based mass suspected to be RCC that was treated by percutaneous cryoablation, only later to find that the mass was UTUC on concurrent diagnostic needle biopsy. Subsequent completion nephroureterectomy demonstrated no residual viable UTUC in the kidney, only ghost tumor cells with reactive changes in the cryoablation site.
Case Presentation
A 67-year-old female presented to the emergency department for workup of gross hematuria. Cystoscopy revealed no intravesical lesions. CT scans revealed a 2.5 cm, well circumscribed left upper pole endophytic renal mass with no obvious collecting system involvement, concerning for RCC. Given the options of surveillance, percutaneous ablation or partial nephrectomy for a presumed RCC, the patient opted to proceed with cryoablation. Needle biopsy obtained at time of cryoablation later returned as high-grade papillary UTUC. Repeat imaging with CT IVP and CT Chest showed post-cryoablation changes without evidence of residual tumor or metastatic disease. About six weeks after cryoablation, the patient opted to undergo a completion robotic-assisted laparoscopic left nephroureterectomy, regional lymphadenectomy, and instillation of intravesical gemcitabine. Pathology of the left kidney, ureter, bladder cuff and 17 para-aortic lymph nodes demonstrated no viable UTUC (pT0N0).
Conclusions
We present the first documented case of a small unexpected UTUC with complete pathologic response to cryoablation treatment. For high-grade UTUC, nephroureterectomy remains the consensus recommendation from the National Comprehensive Cancer Network, American Urological Association, and European Association of Urology. Currently, cryoablation has no proven role in the treatment algorithm for UTUC. However, a handful of case reports and one active phase II trial suggest further investigation may be warranted into the potential role of cryoablation in the treatment of select cases of UTUC.

Published: December 2024

Abstract

Backgroud: This study aimed to utilize clinical metagenomic next-generation sequencing (mNGS) data to analyze the genomic characteristics of Mycoplasma pneumoniae (M. pneumoniae), thereby providing guidance for disease surveillance, prevention and control.
Methods: Clinical samples were sequenced and subjected to mNGS on a MGISEQ-200 sequencer platform using 50bp single-end (SE50) mode. The metagenomic data of samples identified with M. pneumoniae infection (sequence coverage >90%) were de novo assembled for genome comparison, molecular typing and phylogenetic analysis.
Results: Of the three genomes de novo assembled, two with high-quality sequences were analyzed. Genome comparison indicated that the inconsistent regions of the genome were mainly located on the repetitive DNA elements of M. pneumoniae. Genotyping revealed that the two characterized samples, one belonged to ST3 (P1 type 1), while the other was typed to ST7 (P1 type 2). In addition, the phylogenetic tree was constructed successfully with credible bootstrap values.
Conclusion: The clinical mNGS using SE50 strategy could be used for M. pneumoniae detection in patients with low cost and short turnaround time. Meanwhile, the sequencing data could be used for genotyping and genetic characterization of M. pneumoniae as well if the sequence coverage and depth were high enough.

Abstract

Introduction: The death of a relative after an intensive care unit stay can lead to mental disorders as post-traumatic stress disorder or complicated grief. During the first SARS-CoV-2 lockdown in France, social restrictions limited the opportunity to apply family-centered care in intensive care unit, increasing the risk of post-traumatic stress disorder or complicated grief.Methods The psychiatric and other intensive care unit teams at Toulouse University Hospital, France, have created a temporary service known as OLAF (Opération de Liaison et d’Aide aux Familles). OLAF provided psychological phone support to family members of intensive care unit patients. Then, we investigated the impact of the OLAF service on complicated grief, comparing the prevalence of 12-month complicated grief after death in two groups: relatives provided with support via the OLAF service and a control group (standard of care).Results Of the twenty-five bereaved family members recruited, five (20%) presented with complicated grief at twelve months. The groups had no difference on complicated grief diagnosis. An explanatory model found that complicated grief symptoms intensity was mainly explained by post traumatic disorder symptoms intensity (R2 = 0.73, p = 6.21e− 05*). As the only factor significantly associated with complicated grief intensity, we found a predictive value of post-traumatic stress disorder score on complicated grief diagnosis at twelve months in a ROC curve model.Conclusion There was no difference in the prevalence of complicated grief with OLAF service. Failing to prove its effectiveness, we found post-traumatic stress disorder symptoms intensity on the PTSD Checklist for DSM-5 (PCL-5) as the only factor associated to complicated grief in our cohort. We found that this scale could also predict the complicated grief risk at twelve months.Trial registration: The study was approved by our ethics board (CPP 2020-54, ClinicalTrials.gov, Identifier: NCT04470869), and all participants provided informed oral consent.

Authors: Zhang Yanxin , Fu Xinlu , Gu Yingyan , Lu Dan 
Published: December 2024

Abstract

Background
To explore the diagnosis and clinical management of delayed-interval delivery of the twin and the near- and long-term outcomes of mother and fetus.
Case presentation
A 31-year-old pregnant woman was admitted to the hospital on March 23, 2022 due to “28 weeks of menopause with spontaneous vaginal discharge of tissue for 2 hours”. On March 26, 2022 a stillborn fetus was delivered. After delivering a stillborn fetus, the patient was immediately given high ligation of the umbilical cord, antibiotics to prevent infection, atosiban to inhibit contractions, magnesium sulfate to protect the fetal cerebral nerves, and hospitalized to closely monitor the condition of the mother and the other fetus, successfully delivering a baby girl vaginally at 34 + 2 weeks, and no significant complications have been observed in both mother and baby by the two-year follow-up.
Conclusion
Delayed-interval delivery of the twin(DIDT) is a specific complication of twin pregnancies, and proper clinical management can improve the survival of the second fetus. Delayed-interval delivery(DID) may effectively prolongs the gestational age of the delivered fetus and reduces neonatal morbidity and mortality after birth.

Published: December 2024

Abstract

Microfocused ultrasound (MFU) and (MRF) are non-invasive modalities widely used for skin rejuvenation and are often combined with injectables, including neuromodulators and soft tissue fillers. However, large-scale, long-term safety data on such combination therapies are lacking. To address this gap, we conducted a retrospective chart review at two private practice dermatology clinics in South Korea from June 2005 to December 2023. A total of 1,040 patients were included, comprising 515 (49.5%) and 525 (50.5%) patients undergoing MFU and MRF, respectively. Regarding combination therapy, the patients received neuromodulators (76.9%) or dermal filler injections using hyaluronic acid (HA) (17.3%) or poly-L-lactic acid (PLLA) (5.8%) in conjunction with MFU/MRF. Documented adverse events included one case of paradoxical bulging and three cases of eyelid ptosis among those treated with MFU/MRF and neuromodulators (overall incidence: 0.1% and 0.4%, respectively), two cases of surface irregularity among those treated with MFU/MRF and HA fillers (overall incidence: 1.1%), and one case of cheek asymmetry among those treated with MFU/MRF and PLLA injections (overall incidence: 1.7%). No adverse events such as necrosis, burns, filler migration, or unexpected premature loss of filler were reported. While limited by its retrospective design and the inclusion of only two dermatology clinics, which restricts the generalizability of the findings, our study highlights the favorable long-term safety profile of combining MFU and MRF with cosmetic injectables. Our study offers reassurance to clinicians and patients considering these approaches.
Additive-Specific Influences on Non-Classical Nucleation Pathways in Industrially Relevant Minerals

Published: December 2024

Abstract

Additives, comprising small quantities of organic and inorganic molecules, are crucial for controlling the crystallization of various (bio)materials; however, their mechanisms remain poorly understood. By integrating in situ high-energy X-ray scattering with potentiometric titrations, we examined the impact of industrially relevant additives on the nucleation pathways of portlandite and gypsum. While both minerals undergo multistep nucleation, portlandite transitions gradually from a disordered to an ordered phase, whereas gypsum exhibits an abrupt transition. These distinct non-classical pathways and their pH conditions correlate with the mineral-specific effects of the additives. Notably, additive effects extend beyond the classical models, such as cation-binding, exerting influence primarily during the prenucleation stage. Moreover, additives demonstrate a dual role by simultaneously delaying and accelerating different stages of nucleation, highlighting their multifaceted impact on the crystallization process. These findings offer valuable insights for designing tailored additives to optimize industrial crystallization processes and advance the understanding of biomineralization mechanisms.

Published: December 2024

Abstract

This study aims to delineate groundwater potential (GWP) zones of the Haryana state, India, using geospatial techniques for the year 2023. In this, multiple thematic layers created and integrated through geographic information system (GIS) and the analytical hierarchy process (AHP). The data utilized in this research were collected from multiple sources, including the shuttle radar topography mission (SRTM), Sentinel-2 satellite imagery, the food and agriculture organisation (FAO), and the India meteorological department (IMD). Thematic layers including slope, land use/land cover (LULC), soil, geology, drainage density, and lineament density, were created and weighted through the AHP. The layers were subsequently integrated through the weighted overlay analysis (WOA) method to create a GWP map for the area. This GWP map of the year 2023 was compared utilizing groundwater level (GWL) data of the year 2018 from the Central Ground Water Board (CGWB), resulting in a similarity rate of 77.55%. The results indicate that the moderate GWP zone covers 3.71% of the study area, followed by the high GWP zone, which covers 33.24% of the study area. Very high GWP covers only 11.96% of the region. The low and very low GWP zones encompass 7.59% and 3.51%, respectively. The results show that most of the territory has moderate to high GWP, with minor areas having low or extremely low potential. This shows the efficacy of GIS-AHP methods in identifying GWP zones and serves as a crucial instrument for the management of water resources in arid regions such as Haryana.
