Using the Trust Management Mechanism as a Way to Prevent Conflicts of Interest in the Public Service: the Experience of Canada, Chile and Albania
Authors: Gorokhova Svetlana Sergeevna
Published: September 2022

The subject of the study is the legislative and law enforcement experience of countries such as Canada, Chile and Albania in the use of different forms of trust management of property of civil servants and officials as a tool to overcome conflicts of interest in the civil service. The relevance of this study is confirmed by the fact that, on an equal footing with the United States, these states are among the few using this tool, as is the Russian Federation. However, the domestic legal regulation of this institution is still not perfect enough, therefore, it is important to study the experience of those states where there is such a practice. The scientific novelty of the research is determined by the fact that at present there are practically no works containing an analysis of the institute in question. In the course of the study, the following conclusion was made: What is common to the legislation of all the countries considered is that each of these states strives, by virtue of its capabilities, to free the actions of the trustee as much as possible from the influence of the founder of the trust management on him, that is, to ensure the independence of the former from the latter on the management of the entrusted property. However, as the researchers note, even in the most advanced and strict variants, it is hardly possible to avoid the interaction of stakeholders completely. Nevertheless, at least formally, all regulations concerning this issue establish a rule according to which the trustee should not be affiliated with the principal through any channels. This can be applied quite easily in Russian legislation.
Man and Being as factors of Culture dynamics in the concept of permanent Modernity
Authors: Maltsev Yaroslav Vladimirovich
Published: September 2022

The article examines the dynamics of culture as a result of self-unfolding and self-knowledge of being, the agent of which is a person who is both an actor of himself, his own being, and creating culture as a shell of the "second" being, as a screen (S. Zizek), the stage on which his action unfolds, his practice of cognition of being and himself (including as part of being). There is a folding of the triad of being, man and culture, correlating with the well-known formula of Lacan: Real, Imaginary, Symbolic. Within the boundaries of this triad, there is a subject-subject dialogue between man and man, man and being as equal objects in relation to co-creation, co-being, co-cognition. The article correlates with the current search for new ontological theories (object-oriented ontology, speculative realism, assembly theory, etc.), the desire to rethink the role and meaning of the subject (which S. Zizek calls for), to rethink Hegel and actualize his philosophical heritage (again, S. Zizek's thesis), with the search for new concepts that would explain the processes taking place in culture in a better way than the postmodern theory does (L. Hutcheon). The article proposes to consider the dynamics of the genesis and evolution of culture as a correlation of autonomous phenomena of the mind, as a result of reflection by being itself through its own thinking forms - the living: the interaction of being with its own thinking forms for the inclusion of objects of being in the movement of being and its self-disclosure, the disclosure of ways to be, the essence of the immanent property of being, revealed in the procedures of the search for truth, within the boundaries of which culture arises.

Proper thermal management of an electric motor for vehicle applications extends its operating range. One cooling approach is to impinge Automatic Transmission Fluid (ATF) onto the rotor end ring. Increased ATF coverage correlates to enhanced heat transfer. Computational Fluid Dynamics (CFD) analytical tools provide a mechanism to assess motor thermal management prior to hardware fabrication. The complexity of the fluid flow (e.g., jet atomization, interface tracking, wall impingement) and heat transfer makes these simulations challenging. Computational costs are high when solving these flows on high-speed rotating meshes. Typically, a Volume-of Fluid (VOF) technique (i.e., two-fluid system) is used to resolve ATF dynamics within this rotating framework. Suitable numerical resolution of the relevant physics for thin films under strong inertial forces at high rotor speeds is computationally expensive, further increasing the run times. In this work, a numerical study of rotor-ring cooling by ATF is presented using a patent automated Cartesian cut-cell based method coupled with Automatic Mesh Refinement (AMR). This approach automatically creates the Cartesian mesh on-the-fly and can effectively handle complex rotating geometries by adaptively refining the mesh based on local gradients in the flow field which results in better resolution of the air-ATF interface. A Single non-inertial Reference Frame (SRF) approach is used to account for the rotating geometry and to further improve the overall computational efficiency. Quasi-steady state conditions are targeted in the analysis of the results. Important physics such as ATF jet structure, velocity detail near the air-jet interface, ATF coverage/accumulation on the ring surface, and cooling capacity are presented for a low-resolution Reynolds averaged Navier-Stokes (RANS), high-resolution RANS, and high-resolution Large-Eddy Simulation (LES) models. Computations are scaled over hundreds of cores on a supercomputer to maximize turnaround time. Each numerical approach is shown to capture the general trajectory of the oil jet prior to surface impingement. The high-resolution LES simulation, however, is superior in capturing small scale details and heat transfer between the free jet and surrounding air.

Sugarcane (Saccharum officinarum L.) is a plantation crop that is used as raw material for the consumer sugar and industrial sugar. The need for sugar is increasing every year but is not matched by an increase in sugarcane production due to several factors including cultivation management that is not optimal. Sugarcane production begins with good nursery management, including using genetic of seeds and the right planting media. One alternative to improve the quality of growing media is to use humic acid (HA) as a soil enhancer. This study aims to determinate the effect of giving HA on the morphological characteristics of sugarcane seedlings of Bululawang variety (BL). This research was carried out in an integrated laboratory greenhouse at the Polytechnic LPP Yogyakarta from Maret to July 2021. This study used a non-factorial completely randomized design (CRD) with five treatments and three replications consisting of P0 (control), P1 (25 ml.polybag-1), P2 (50 ml.polybag-1), P3 (75 ml.polybag-1), and P4 (100 ml.polybag-1). The morphological characteristics observed is plants height (cm), number of leaves (strands), stem diameter (mm) and longest root length (cm). the results of the study were analyzed using ANOVA at the 5% level and continued using the Duncan Multiple Range Test (DMRT) at the 5% level. The result showed the effect on morphological characters on all observation variables where the P3 treatment had the best growth and morphological characters, so that in general the additional of HA affected the morphological characteristics of sugarcane seedlings of BL varieties.

Objetivo: Analisar a saúde mental e Síndrome de Burnout (SB) em profissionais da área da saúde. Revisão bibliográfica: Os problemas de saúde mental já iniciam, muitas vezes, durante a graduação pela da alta carga de estresse. Horários desequilibrados e aumento do trabalho administrativo foram definidos como fatores-chave na produção de saúde mental ruim entre os profissionais de saúde. Em médicos, a própria natureza da profissão como a cultura competitiva pode levar ao surgimento de preocupações com a saúde mental. Uma revisão sistemática recente indicou que mais de 50% dos médicos e enfermeiros estão sofrendo de SB que é uma desordem adaptativa a fatores estressantes crônicos relacionados à alta demanda no ambiente de trabalho. Considerações finais: A saúde mental dos profissionais de saúde impacta tanto nas suas vidas pessoais quanto no meio laboral com redução de produtividade e maiores erros médicos. Nesse contexto, é imperativo que os serviços de saúde atendam às necessidades fisiológicas fundamentais dos profissionais de saúde. Isso envolve fornecer nutrição adequada, garantir que as rotações/horários sejam cumpridos para descanso suficiente e limitar o possível excesso de trabalho que é um fator conhecido para o burnout.

Objective: Evaluate the association between anxiety, sleep and awake bruxism in volunteers that practice resistance training. Methods: One hundred and two volunteers answered four questionnaires: checklist of oral behaviors to diagnostic the awake bruxism, international classification of sleep disorders to identify sleep bruxism, generalized anxiety disorder 7 (GAD-7) which checks levels of anxiety symptoms and characterization of resistance training (reason, frequency, periodicity and period of training, as well as the perception of orofacial pain or clenching during training). A descriptive analysis, Pearson's and Tukey test (α = 0.05) was made. Results: Dental clench during training and the perception of orofacial pain after this activity had a significant association (ρ = 0.36; p < 0.001). The extensive resistance training (ρ = 0.30; p = 0.005) and the frequency of training (ρ = 0.40; p > 0.001) also influenced the perception of pain. The diagnostic of sleep and awake bruxism proved to be associated (ρ = 0.36; p <0.001). Sleep bruxism was also associated with higher levels of anxiety symptoms. (ρ = 0.36; p = 0.002). The other variables showed no statistical association. Conclusion: It is concluded that the active adult population participating in this study has inadequate knowledge about functional foods, which are not included in their usual diet.

Application of the international system for reporting serous fluid cytopathology on reporting various body fluids; experience of a tertiary care hospital
Authors: Kolte Sachin , Zaheer Sufian , Aden Durre , Ranga Sunil
Published: September 2022

Objectives:

Cytological examination of effusion sample is a preliminary and minimally invasive method for the diagnosis of body fluids. Recently, the International System For Reporting Serous Fluid Cytopathology (ISRSFC) and the Indian Academy of Cytologist (IAC) have published guidelines for reporting effusion cytology and calculating the risks of malignancy (ROMs) for each defined category. We report our 2 years of experience in reclassifying and assessing the feasibility of applying ISRFSC and IAC categories to effusion fluid and to provide an estimate of the risk of malignancy for each diagnostic category.

Material and Methods:

Cytological reports of patients from January 2019 to December 2020 were retrieved and reclassified into a five-tiered classification scheme as per ISRSFC guidelines. Cellblock and immunohistochemistry were performed in selected cases. Clinico radiological and histopathological information were obtained and correlated with the cytological findings wherever available.

Results:

In the study, 652 cases were included during the 2 years. Out of these, 328 (50.3%) were women and 314 (47.3%) were men. Patient’s ages ranged between 2 92 years with a mean age of 47.4 years. There were 366 (56.1%) cases of ascitic fluid followed by 262 (40.1%) cases of pleural fluid and 24 (3.8%) cases of pericardial fluid in the analysis. Of all the cases, 13 (2%) were non-diagnostic (ND), 464 (71.6%) were negative for malignant (NFM) cells, 16 (2.4%) were atypia of uncertain significance, 31 (4.7%) were suspicious of malignancy, and 125 (19.3%) were malignant. Cellblock was prepared in 65 cases. Lung cancer followed by breast cancer was the most common malignancies involving the pleural effusion and ovarian cancer was the most common cause of peritoneal effusion. ROM for each diagnostic category was 23% for ND, 25% for NFM, 56% for the atypical category, 80.6% in suspicious, and 90% were for positive for malignancy category.

Conclusion:

The use of a five-tiered system as per the ISRFC and IAC guidelines are feasible for the standardized reporting of effusion samples, thus avoiding subjective variation of reporting.
Urticaria and comorbidities
Authors: Gotua Maia , Agondi Rosana Câmara , Cherrez-Ojeda Ivan
Published: September 2022

Urticaria is a mast cell (MC)-driven skin disease. Degranulation of these cells is triggered by the activation of several receptors on its surface. The activation of MC in chronic spontaneous urticaria (CSU) appears to be associated with an autoimmune etiology. Certain comorbidities such as autoimmunity, infections, allergy, emotional stress, and metabolic syndrome are frequently associated with chronic urticaria (CU). The objective of this review is to highlight the frequent association between CU and several comorbidities, which can lead to a worse prognosis for the underlying disease. We searched for original and review articles on CU and comorbidities in PUBMED, abstracts published in AAAAI and EAACI; all of them in English. Our review reinforced how CSU, being itself an autoimmune disease, is strongly linked to several other autoimmune diseases. Besides autoimmunity, emotional stress was considered another frequent comorbidity associated with CU and also a trigger factor for urticaria exacerbation. Some studies recently considered CU as a low-grade chronic inflammatory condition and may be associated with metabolic syndrome. In conclusion, CU is considered a heterogeneous disease with distinct clinical features. It is worth remembering that CU should not be considered just a skin disease and its complete control could minimize a worse clinical outcome.

Hasil jagung manis di Indonesia per hektarnya masih rendah. Untuk mendapatkan hasil yang maksimal, maka selain pupuk anorganik, tanaman jagung manis membutuhkan pupuk organik. Salah satu sumber pupuk organik adalah pupuk kandang kambing karena kambing merupakan bagian integral dari sistem usahatani yang diterapkan di pedesaan. Kandungan hara yang rendah dari pupuk kandang kambing menyebabkan kebutuhan per hektarnya menjadi sangat banyak dan kesulitan dalam penggadaannya. Untuk itu perlu dilakukan pengkayaan dengan menggunakan batuan fosfat, dan zeolit.  Sementara itu, nilai estetika pupuk organik diatasi dengan membentuk pupuk granul. Percobaan pengujiaan efektivitas pupuk organik di lapangan dengan menggunakan Rancangan Acak Kelompok (RAK) faktor tunggal dan diulang 3 kali. Hasil penelitian menunjukkan bahwa pengkayaan pupuk kandang kambing dengan BFA atau Zeolit dapat meningkat nilai pH, kadar C-organik dan bahan organik tanah. Zeolit meningkatkan pertumbuhan tanaman Jagung Manis pada parameter tinggi tanaman dan jumlah daun, sedangkan BFA meningkatkan diameter daun. Takaran Zeolit 4,5% dapat menghasilkan berat dan panjang tongkol paling tinggi dibandingkan perlakuan lainnya.
Electrochemical detection of dopamine using a simple redox cycling-based device
Authors: Şen Mustafa
Published: September 2022

Here, a dual ITO microchip was fabricated for high sensitive detection of dopamine (DA) based on redox-cycling. The ITO electrodes with 3×3 mm working areas were made via photolithography and dry etching processes. The microchip was obtained by first aligning the working areas of two ITO electrodes to overlap and then fixing them in that position using a double-sided tape, which also formed a sealed microchannel between the ITO electrodes for test solution delivery. The ITO electrodes and microchips were electrochemically characterized using EIS, cyclic voltammetry and chronoamperometry. Compared to a single ITO electrode in a microchannel, the microchip had a significantly higher signal due to redox cycling. The microchip was lastly used for the detection of DA at varying concentrations. According to the results, the microchip had an LOD of 0.15 μM in a linear detection region of 0.1 to 50 μM. The microchip requires less than 1 μl of solution to complete the analysis and has great potential to be applied for immunosensing.

Depletion-driven assembly has been widely studied for micron-sized colloids, but questions remain at the nanoscale where the governing physics are impacted by the stabilizing surface ligands or wrapping polymers, whose length scales are on the same order as those of the colloidal core and the depletant. Here, we probe how wrapping colloidal tin-doped indium oxide nanocrystals with polymers affects their depletion-induced interactions and assembly in solutions of polyethylene glycol. Copolymers of polyacrylic acid grafted with polyethylene oxide provide nanocrystal wrappings with different effective polymer graft densities and molecular weights. (Ultra) small angle X-ray scattering, coarse-grained molecular dynamics simulation, and molecular thermodynamic theory were combined to analyze how depletant size and polymer wrapping characteristics affect depletion interactions, structure, and phase behavior. The results show how depletant molecular weight, as well as surface density and molecular weight of polymer grafts, set thresholds for assembly. These signatures are unique to depletion-driven assembly of nanoscale colloids and mirror phase behaviors of grafted nanoparticle--polymer composites. Optical and rheological responses of depletion-driven assemblies of nanocrystals with different polymer shell architectures were probed to learn how their structural differences impact properties. We discuss how these handles for depletion-driven assembly at the nanoscale may provide fresh opportunities for designing responsive depletion interactions and dynamically reconfigurable materials.
PARTICIPACIÓN DE LAS MUJERES EN LA FORMACIÓN DE INGENIEROS: UNA MIRADA DESDE LAS INSTITUCIONES DEL CAUCA Y VALLE DEL CAUCA
Authors: Rojas Johanna
Published: September 2022

Desde la década del sesenta, en Colombia se viene presentando un gran avance educativo con la oferta de programas de ingeniería. En coherencia con ello en los departamentos en mención, se cuenta con un importante crecimiento, que para el año 2020 presentaba una oferta superior a 100 programas de ingeniería. Este gran avance se ha venido construyendo y ha sido posible gracias a la contribución de varias generaciones de ingenieras, en distintos ámbitos; con su labor como docentes, investigadoras o administrativas. La participación de las mujeres en el mundo de la ingeniería se percibe estigmatizada, por considerarse un área de conocimiento tradicionalmente exclusiva del género masculino. En razón a esto, la Red de Ingeniería Industrial Suroccidente; busca más allá de porcentajes, precisar características del comportamiento de contratación de profesionales del género femenino, en actividades administrativas, docentes, investigativas y de proyección social, que aporten a la formación de ingenieros, de manera que se alcance un valioso insumo que permitirá establecer razones fundamentales que motivan a las mujeres a tomar esta decisión. Según el último informe presentado por la Unesco, en 2018, en el mundo, las mujeres representaban el (43%) de los profesores en la educación superior, porcentaje que se reduce aún más cuando se analiza la participación de la mujer en altos cargos directivos. En Colombia se estima que el porcentaje de participación de las mujeres como profesoras en educación superior (38%) se ha incrementado en un 5% entre 2007 y 2018, al igual que la participación en investigación. Según los datos entregados por Minciencias (2019), sólo el 38% de los investigadores científicos en Colombia eran mujeres. Algunos estudios mencionan que el tipo de contratación, salario, estudios especializados y la posibilidad de ocupar altos cargos en IES, siguen siendo indicadores de la inequidad que prevalece en este tipo de organizaciones. De ahí que, el rol de la mujer en cargos administrativos, docencia e investigación, tiene un impacto visible en términos del liderazgo, el fortalecimiento social equitativo y el cambio del paradigma de género en torno a la ingeniería. Teniendo en cuenta lo anterior, la identificación de rasgos de conducta y el entorno, facilitarán la generación de un análisis referente a formación pos gradual, motivación de ingreso, permanencia, retos importantes, así como posibles causas del desistimiento de participar en facultades de ingeniería de IES en el Cauca y Valle del Cauca.

Objective: To explore the value of circulating tumor cells in evaluating the effect of chemotherapy for advanced non-small cell lung cancer. Methods: Sixty-two patients with advanced non-small cell lung cancer who received chemotherapy in the Affiliated Hospital of Hebei University from January 2018 to December 2021 were selected as the research subjects. The positive rate of CTCs after two weeks of chemotherapy and four weeks of chemotherapy as well as the evaluation of imaging efficacy were observed and analyzed. Results: Based on the clinical data of the patients, the positive rate of CTCs in male patients was 77.78%, that in female patients was 80.77%, that in patients ? 60 years old was 78.13%, that in patients < 60 years old was 76.67%, that in squamous cell carcinoma was 79.31%, that in adenocarcinoma was 78.79%, and that in highly differentiated, moderately differentiated, and poorly differentiated + undifferentiated CTCs was 66.67%, 84.21%, and 90.91%, respectively; there was no statistical difference in the general data. The positive rate of CTCs was 88.71% before chemotherapy and 66.13% after two weeks of chemotherapy, in which the difference was statistically significant; the positive rate of CTCs four weeks after chemotherapy was 59.68%, which was statistically significant compared with that before chemotherapy; however, there was no significant difference between two weeks after chemotherapy and four weeks after chemotherapy. After chemotherapy, 35 patients had CR+PR, 19 patients had SD, and 8 patients had PD. The proportions of CR+PR, SD, and PD in the imaging evaluation results were 56.45%, 30.65%, and 12.90%, respectively. After kappa consistency test, it was found that the consistency was good. Conclusion: CTCs can be used as one of the indicators to evaluate the effect of chemotherapy for advanced non-small cell lung cancer. The results are consistent with those of imaging evaluation. The detection of CTCs can be widely used as one of the clinical indicators.
