Euphemisms Inside and Outside the University Context in the Times of the Covid-19 Pandemic: The Students’ Perspective
Authors: Bloch-Rozmej Anna
Published: November 2023

The aim of this paper is to explore the phenomenon of euphemisms as perceived by Polish university students in the context of the COVID-19 pandemic. The article presents an overview of the major theoretical issues related to the linguistic concept of euphemisms and their use in everyday situations during the years of the pandemic. The data for this study were collected through an online questionnaire administered in December 2022. This stage of the research was preceded by a close examination of three internet blogs in terms of COVID-related euphemistic vocabulary. The discussion of the findings is intended to reveal the students’ perspective on the use of euphemisms, including the reasons for their use and the types of situations where such language forms are employed. The results are expected to shed some light on the possible impact that euphemistic language might have on student-teacher interactions. Another significant aspect addressed in this paper is the relationship between euphemisms and language creativity.
Do Blind People Need Gestures to Communicate Effectively?
Authors: Sak-Wernicka Jolanta
Published: November 2023

Gestures are known to play an important role in communication, but to this day it is still not clear what impact visual impairment has on gesture production. The main objective of this article is to investigate: (1) whether the lack of vision reduces (or completely blocks) gesture production in blind individuals, and (2) whether this reduction in (or lack of) gestures has an effect on their abilities to communicate. To address this issue, we performed an experiment in which congenitally blind and sighted people were compared on the number and types of gestures they produced when playing the word-guessing game TABOO. The results obtained confirm that, compared to people who are sighted, blind individuals produce significantly fewer gestures when they communicate. This, however, does not have any negative impact on how effective they are in conveying their messages. The analyses also show that gestures play different roles for blind and sighted people.

The Atlantic Forest is among the 36 biodiversity hotspots of the world. The southern region of this biome covers 52 conservation units (CUs), including the Bela Vista Biological Refuge (RBBV), which has actions based on biodiversity conservation, scientific research, and environmental education. Biodiversity is the basis for different ecosystem services that can be carried out by social wasps, essential in terrestrial environments. Brazil has the richest fauna of social wasps (Vespidae, Polistinae) on the planet (381 species); however, some Brazilian states, such as Paraná, are “undersampled.” This study was carried out with the goal of inventorying the fauna richness of social wasps in the Atlantic Forest. This biome is located in the RBBV, Paraná, Southern Brazil, and the collections took place from September 2021 to May 2022, totaling 20 days of sampling. Active search with the aid of insect entomological nets in trails near aquatic environments was used. A total of 18 species of social wasps were recorded, including four new records for the state of Paraná. This study recorded species restricted to some biomes and others of wide geographical occurrence; therefore, the RBBV is an important CU for maintaining the fauna of social wasps in the state of Paraná.

Há boi pastando, há desmatamento e outras coisas mais: a retrato da da RESEX Chico Mendes
Authors: Fittipaldy Márcia Cristina Pereira de Melo , Castelo Carlos Estevão Ferreira
Published: November 2023

Este artigo é parte integrante de uma pesquisa de maior folego que tratou das políticas de exploração dos produtos da biodiversidade e suas repercussões na vida dos seringueiros da Reserva Extrativista Chico Mendes no Estado do Acre. O objetivo foi destacar como a pecuária vem se consolidando como a principal atividade econômica dos seringueiros da Resex Chico Mendes (Resex). Consolidação que soa um tanto paradoxal, tendo em vista que a criação das Resex se deu em decorrência de uma mobilização dos seringueiros contra a derrubada da floresta para instalação de pastagens. As principais estratégias metodológicas utilizadas foram revisão bibliográfica, pesquisa documental e pesquisa de campo. O principal resultado observado foi que o território da Resex está sendo transformando em área de interesse dos grandes grupos empresariais. Os seringueiros estão se reinserindo na lógica do capital, tornando-se produtores para o mercado em setores produtivos e de uso do solo florestal diferentes do extrativismo tradicional.

Movement of goods across the border always attracts close attention of authorities in charge of criminal intelligence and surveillance operations. It is common knowledge that provisions of the Criminal Code of the Russian Federation that regulate origination of criminal liability for smuggling are usually of a blanket nature; as it is known, procedural provisions can also be blanket but the law enforcers tend to forget about it. A smuggling charge has been brought against a mail recipient following just one criminal intelligence and surveillance operation. The pre-trial investigation authority and the first instance court have ignored arguments of the defense on the innocence of the recipient of the mail, which has become a sort of a pig in a poke for him. The investigative and judicial mistakes have been found only by the second instance court, which has resulted in sentence remission and criminal case termination due to the absence of the event of a crime. The study of the law enforcement, right protection and judicial activities carried out by us and summarized in this article analyzes the generation a suspicious attitude to mail recipients by customs, the mechanism of bringing a false accusation against one of such recipients, irresponsible consolidation of such accusation in acts of pre-trial investigation authorities and the first instance court.
Contingency Fee: Statutory Regulation, Features of Fixing in an Agreement, Risks, Judicial Practice
Authors:   Presiding Judge of the First Chamber of Lawyers of the Altai Territory, Zaytsev Vladimir V.
Published: November 2023

The article is devoted to the institution of contingency fee to lawyers for the provision of legal services, its ambiguous assessment, both in legal doctrine and in the current judicial practice, which creates certain obstacles to the introduction of contingency fee in the mechanism for improving the quality of professional legal assistance. Based on the analysis of the acts of the current legislation and the legal positions of the highest court, the author comes to the conclusion that, despite the ambiguity of the attitude towards the contingency fee as a type of incentive payment for a lawyer, its final legalization and a uniform understanding at the level of law enforcement practice are only a matter of time and firstly depend on consistent and worked out procedures on the part of the legislator.
Procedural Rights of a Representative of a Chamber of Lawyers in the Course of Investigative Actions Performed in Respect of Attorneys
Authors:   Professor of the Department of Criminal Procedure of the Ural Law Institute of the Ministry of the Interior of the Russian Federation, LL.D., Associate Professor, Stelmakh Vladimir Yu.
Published: November 2023

The article analyzes the procedural rights of the authorized representative of the Chamber of Lawyers as a participant in investigative actions, and the procedure for exercising these rights. It is argued that the participation of a representative of the bar chamber is aimed at ensuring the inviolability of information constituting a lawyer’s secret, and this circumstance determines the scope of the procedural rights of this subject. By participating in the conduct of the investigative action, the said subject represents the bar community, and cannot be considered either understood, nor as a specialist, nor as a lawyer or representative of the specific lawyer in respect of whom the investigative action is being carried out. The representative of the bar, on the one hand, defends the private interests of the bar community, and on the other hand, contributes to the implementation of public legal interests, ensuring the legality of the investigative action. On the basis of a systematic analysis of the law, the procedural rights are summarized and detailed, which the representative of the bar chamber is endowed with participation in investigative actions carried out against lawyers. Currently, these rights are systematized in a corporate act issued by the Federal Chamber of Lawyers of the Russian Federation. Taking into account the high significance, the feasibility of securing these procedural rights directly in federal legislative acts is justified.
A Novel Method to Assay Aspirin in Pharmaceutical Formulations by Smartphone Camera-Based Image Scanning Densitometry
Authors: KHAN Rimsha , ANWAR Jamil
Published: November 2023

Aspirin, a widely-used anti-inflammatory drug, can lead to serious consequences when overdosed. Therefore, there's a need for simple, cost-effective methods to determine its concentration and mitigate potential risks. This study aimed to develop a method for assessing aspirin in pharmaceutical preparations without the need for expensive equipment and with minimal sensitivity to ambient light. In this work, aspirin was subjected to a reaction with Fe(III), leading to the formation of violet-colored spots on filter paper and a 96-microwell plate. These colored spots were then captured using a smartphone in normal lighting conditions and analyzed on a computer. The integrated density of each spot was measured using a novel grayscale technique, and a calibration curve was created to relate integrated density to aspirin concentration. Analytical parameters and reagent concentrations were optimized for accuracy. To validate the method, three commercial aspirin samples were assayed and compared to ultraviolet-visible spectrophotometry, a reference method. The developed technique demonstrated excellent precision (coefficient of variation <0.68%) and relative errors below 5.2%. When compared to traditional color models like red-green-blue (RGB) and hue-saturation-luminosity (HSL), the grayscale model showed superior correlation (R2> 0.996), while the RGB model yielded less precise results (R2= 0.792). This study showcased the effectiveness of a cost-effective methodology for accurate aspirin quantification using a smartphone camera, even in the presence of ambient light.

Published: November 2023

Background. Among malignant neoplasms in HIV-infected patients lymphomas occupy a special place due to the high incidence, course characteristics, and difficulties that arise during diagnosis and during antitumor drug therapy. Hodgkin’s lymphoma (HL) is not an AIDS indicating disease, but the risk of its development in people infected with HIV is 5–25 times higher than the incidence of HL in the general population. Prior to the use of antiretroviral therapy, the results of standard chemotherapy in HIV-infected patients with HL were significantly worse than in HIV-negative patients. One of the main requirements for drug treatment of this group of patients is the simultaneous use of antiretroviral therapy and chemotherapy. The aim was to study the clinical characteristics and results of treatment of HL in the presence of HIV infection. Materials and methods. The analysis included 24 HL patients with HIV infection who received treatment in the Department of Radiation and Drug Therapy of Hemoblastoses of the MRRC in the period from 2018 to 2022. Treatment program selection was in accordance with the HL treatment protocol developed at our Center. Patients received 4–6 cycles of ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) or 6 cycles of BEACORP (bleomycin, vepesid, doxorubicin, cyclophosphamide, vincristine, dacarbazine, prednisolone) chemotherapy according to the stage of the disease and the risk factors generally accepted for patients with HL. The response to therapy was assessed according to the Lugano-2014 criteria. Descriptive statistics methods were used. Overall survival and progression-free survival were analyzed using the Kaplan-Meier method. Results. HL occurring against the background of HIV is most often represented by a widespread nodal and extranodal lesion, accompanied by symptoms of intoxication (B-symptoms). The use of standard CT regimens as induction therapy for HL in the presence of HIV makes it possible to obtain satisfactory immediate and long-term results of treatment. In our study complete and partial responses were achieved in 94.1 %. With a median follow-up of 12 months survival without progression and overall survival were 75 % and 100 % respectively.

Authors: . Sinky , . Sapna , . Sarita , . Meenakshi , Kumar Vijay , Soni Aarti , Sharma K.D.
Published: November 2023

Background: Salinity stress affects crop yields worldwide. Mungbean, a popular grain legume with protein-rich seeds, is glycophytic and vulnerable to saline stress. Silicon has become a key ingredient that boosts plant enzymatic antioxidant activity and osmoprotectant synthesis, promoting stress tolerance. Methods: In chloride-dominated salinity conditions of 4 and 6 dSm-1, sodium meta-silicate administration strategies were examined in salt-affected mungbean (MH421). Two application strategies were used: foliar spraying at 50 mg/l and 100 mg/l at 30 and 45 DAS and soil addition at 50 mg/kg soil as a solution during planting. The effects of these treatments were examined at 33 and 48 DAS, three days following foliar sodium meta-silicate application. Result: Salinity stress reduced dry weight, nodule counts, gas exchange characteristics and plant water relation features, although Si treatment buffered the detrimental effect to a varied amount. Best effects were obtained with 100 ppm foliar application. Lipid peroxidation and electrolyte loss increased with salinity stress, while Si reduces these losses by scavenging free radicals. Silicon supplementation lowered Na+ and increased K+ absorption. Also, Si altered photosynthetic machinery, Na+/K+ homeostasis, osmolyte synthesis and oxidative stress in mungbean to reduce salinity stress and increase seed yield.

A tanulmány a kisebbségi mentalitásvariációk talán legelső teljes értékű jugoszláviai magyar drámájának, Deák Ferenc Légszomjának színpadi változatával foglalkozik, de kitér a dráma eredeti és csonkított formában megjelent szövegére is. Kontextusként bevezeti az önigazgatás fogalmát, fontos eseményként említi a prágai tavaszt, Deák első drámájának, az Áfonyáknak a bemutatóját és annak hatástörténetét, a Forum Könyvkiadó 1970. évi drámapályázatát, továbbá a Tartományi Belügyi Szolgálat hatáskörének bővülését. A fogalmak és komplex események bővebb leírása nem célja, ám segítségükkel és a forráskutatás módszerével megvizsgálja a Légszomj fogadtatástörténetét és bemutatásának politikai következményeit.
„ILYEN UTAKON ISMERTEM MEG A TÁJ LELKÉT, AMELY AZ ENYÉM IS”
Authors: PAPP Ágnes Klára
Published: November 2023

A puszta (és a vele rokon értelemben használt változatos megnevezések sora) a magyar irodalomban és gondolkodástörténetben kiemelten fontos, épp ezért bonyolult jelentésszerkezettel rendelkező toposzként működik: nemcsak a legkülönbözőbb műfajú írások témájaként vagy helyszíneként, hanem az idők során hozzá kapcsolódó, eltérő töltetű szimbolikus jelentések tekintetében is. Ezt a szerepét mindenekelőtt a magyar identitást tükröző, kifejező, sőt meghatározó helyként nyerte el, elsősorban ennek köszönhetőek a hozzá kapcsolódó történelmi, lélektani, antropológiai gondolatmenetek és az ebből fakadó motívumok, ezt tükröző metaforizációk sora. Ezek után nem meglepő, hogy ezek a jelentéstulajdonítások az élesen megfogalmazott kritikától a mitizáló rajongásig terjednek, ahogy a toposzt újraértelmező művek tára is a romantikus költeménytől a szociográfiai regényig. A dolgozat Illyés Gyulára és a Puszták népére fókuszál.
KISEBBSÉGI ÉLETSTRATÉGIÁK SPIRÓ GYÖRGY ÁLMODTAM NEKED CÍMŰ
Authors: Marko ČUDIĆ
Published: November 2023

Bár az Álmodtam neked novelláskötet Spiró György egyik legnépszerűbb kötete (három kiadást ért meg eddig), a kritika mégsem sorolja a szerző nagy, meghatározó művei közé. Ugyanakkor ez a kötet talán Spiró legönéletrajzibb, legintimebb, leginkább vallomásszerű műve. A novellák, kronológiai sorrendbe szedve, akár egy kortárs nevelődési regény fejezeteiként is olvashatók. A művésszé válás folyamatának bemutatásában többféle kisebbségi élet- stratégiát használ a narrátor, jelen tanulmány ezeket próbálja kidomborítani, problematizálni. Ezek a stratégiák nagyjából három különböző típusra oszthatók fel. Az első típusba a fiatalkori lázadás és a társadalmi mimikri elfogadása közötti ingadozás sorolható, amely minden bizonnyal a narrátor második generációs holokauszt-túlélői státuszából ered, illetve az ezzel járó posztmemória feldolgozásának folyamatából. A második kisebbségi életstratégia-típusba a narrátor vállalt és kemény munkával megszerzett többnyelvűsége és többkultúrájúsága tehető, amely értelemszerűen ráébreszti őt magának a magyar nyelvnek és irodalomnak minor státuszára a világ kultúráiban. A harmadik életstratégia-típus pedig a narrátor ama tudatából táplálkozik, miszerint a „szellem arisztokráciájához” tartozó emberek léte rendkívül törékeny, ám ugyanakkor kivételesen gazdag létezésforma és különös privilégium.

Objetivo: compreender a vivência materna no cuidado alimentar do filho com gastrosquise e discutir a assistência do enfermeiro a essas mães segundo as concepções de Ramona Mercer sobre o papel maternal. Métodos: estudo qualitativo realizado em duas unidades de terapia intensiva (neonatal e cirúrgica) de uma instituição federal no Rio de Janeiro. Foram entrevistadas 11 mães de recém-nascidos com gastrosquise que se alimentavam por via oral e sonda. Os dados foram analisados e interpretados à luz de Bardin e Ramona Mercer. Resultados: as falas evidenciaram dificuldades na construção da identidade materna, visto que alimentar o filho com gastrosquise é desafiador devido à instabilidade clínica, porém, o apoio da enfermagem mostrou-se fundamental nesse processo. Conclusão: dar voz e incluir as mães no cuidado faz com que elas se sintam seguras na criação do vínculo mãe-filho e estabeleçam estratégias para o desenvolvimento do papel materno, mesmo diante dos obstáculos impostos pela malformação.

ABSTRACT
Objective: Ovarian cancer is most common malignancy of women and generally diagnosed at advanced stage therefore tends to have poor prognosis. The inflammatory process is proven involved in malignancy mechanism which Neutrophil Lymphocyte Ratio (NLR) and Platelet Lymphocyte Ratio (PLR) have potential as independent prognostic markers. This research was to evaluate NLR and PLR levels in ovarian cysts among epithelial ovarian cancer patients at RSUP H. Adam Malik Medan
Materials and Methods: This research is a comparative case-control study conducted at Department of Obstetrics and Gynecology at RSUP H. Adam Malik Medan on December 2019 – February 2020. The research sample were 40 patients diagnosed with ovarian cysts and epithelial ovarian cancer, respectively. Bivariate analysis was done with independent T test if data was normally distributed or Mann Whitney if not normally distributed. All results will use a significance value <0.05.
Results: Median NLR level in ovarian cancer group was 2.45 (1.06 – 38.44) and in ovarian cysts group was 2.34 (1.44 – 3.78). Median PLR levels in ovarian cancer group was 12813.94 (3178.08 –19040.0) and in ovarian cysts group was 11138.15 (5026.18–22839.51). Based on analysis test, it was found that there was no statistically significant difference of NLR and PLR levels in ovarian cancer compared to ovarian cysts (p>0.05).
Conclusion: NLR and PLR levels between ovarian cancer and ovarian cyst patient in RSUP H. Adam Malik Medan shows no difference in value. NLR and PLR can still be used as a marker for malignant process in patient suspected with malignancy.

Authors: Singgih Rendy , Kwary Meilyana Maria Isabela , Tamara Yosi
Published: November 2023

HIGHLIGHTS

PE is still one of the contributors to morbidity and mortality which is quite high for pregnant women in Indonesia.
The use of NLR and MEOWS modalities as predictors of preeclampsia incidence shows significant potential and can be applied especially in facilities with limited resources.

 
ABSTRACT
Objective: Describe modalities of detecting the severity of preeclampsia (PE) between neutrophil-to-lymphocyte ratio (NLR) levels and Modified Obstetric Early Warning Systems (MEOWS).
Materials and Methods: We used a systematic search in PubMed, ScienceDirect, and Google Scholar for English articles, full access, published between 2015 – 2023 that evaluated modalities between NLR levels and MEOWS for detecting the severity of preeclampsia which resulted in 208 works of literature. Among the studies we found 14 works of literature that met the PICO inclusion criteria were included in this study.
Results: PE is still one of the high morbidities and mortality in maternal patients. It takes tools to predict the possible risk of PE events that can occur. NLR is one of the markers that become a prognostic modality to determine the severity of PE. MEOWS is one of the tools to assess the level of care of patients who carry out the treatment. NLR and MEOWS can be modalities for predicting PE severity.
Conclusion: NLR and MEOWS can be used even with limited resources. The combined use of NLR and MEOWS can be an alternative and potential modality in detecting PE severity.

Complete Description of Bounded Solutions for a Duffing-Type Equation with a Periodic Piecewise Constant Coefficient
Authors:   Moscow Institute of Electronic Engineering, Alfimov G. L. , Lebedev M. E. ,   Nuclera Ltd, One Vision Park
Published: November 2023

We consider the equation $u_{xx}^{}-u+W(x)u^3=0$ where $W(x)$ is a periodic alternating piecewise constant function. It is proved that under certain conditions for $W(x)$ solutions of this equation, which are bounded on $\mathbb{R}$, $|u(x)|<\xi$, can be put in one-to-one correspondence with bi-infinite sequences of numbers $n\in \{-N,\,\ldots,\,N\}$ (called ``codes'' of the solutions). The number $N$ depends on the bounding constant $\xi$ and the characteristics of the function $W(x)$. The proof makes use of the fact that, if $W(x)$ changes sign, then a ``great part'' of the solutions are singular, i.e., they tend to infinity at a finite point of the real axis. The nonsingular solutions correspond to a fractal set of initial data for the Cauchy problem in the plane $(u,\,u_x^{})$. They can be described in terms of symbolic dynamics conjugated with the map-over-period (monodromy operator) for this equation. Finally, we describe an algorithm that allows one to sketch plots of solutions by its codes.
On Nonlinear Oscillations of a Near-Autonomous Hamiltonian System in One Case of Integer Nonequal Frequencies
Authors:   Moscow Aviation Institute (National Research University), Kholostova O. V.
Published: November 2023

This paper is concerned with the motions of a near-autonomous two-degree-of-freedom Hamiltonian system, $2\pi$-periodic in time, in a neighborhood of a trivial equilibrium. It is assumed that in the autonomous case, in the region where only necessary (which are not sufficient) conditions for the stability of this equilibrium are satisfied, for some parameter values of the system one of the frequencies of small linear oscillations is equal to two and the other is equal to one. An analysis is made of nonlinear oscillations of the system in a neighborhood of this equilibrium for the parameter values near a resonant point of parameter space. The boundaries of the parametric resonance regions are constructed which arise in the presence of secondary resonances in the transformed linear system (the cases of zero frequency and equal frequencies). The general case and both cases of secondary resonances are considered; in particular, the case of two zero frequencies is singled out. An analysis is made of resonant periodic motions of the system that are analytic in integer or fractional powers of the small parameter, and conditions for their linear stability are obtained. Using KAM theory, two- and three-frequency conditionally periodic motions (with frequencies of different orders in a small parameter) are described.

Accurate data on crop canopy are among the prerequisites for hydrological modelling, environmental assessment, and irrigation management. In this regard, our study concentrated on an in-depth analysis of optical satellite data of Sentinel-2 (S2) time series of the leaf area index (LAI) to characterise canopy development and inter-row management of grapevine fields. Field visits were conducted in the Ouveze-Ventoux area, South Eastern France, for two years (2021 and 2022) to monitor phenology, canopy development, and inter-row management of eleven selected grapevine fields. Regarding the S2-LAI data, the annual dynamic of a typical grapevine canopy leaf area was similar to a double logistic curve. Therefore, an analytic model was adopted to represent the grapevine canopy contribution to the S2-LAI. Part of the parameters of the analytic model were calibrated from the actual grapevine canopy dynamics timing observation from the field visits, while the others were inferred at the field level from the S2-LAI time series. The background signal was generated by directly subtracting the simulated canopy from the S2 LAI time series. Rainfall data were examined to see the possible explanations behind variations in the inter-row grass development. From the background signals, we could group the inter-row management into three classes: grassed, partially grassed, and tilled, which corroborated our findings on the field. To consider the possibility of avoiding field visits, the model was recalibrated on a grapevine field with a clear canopy signal and applied to two fields with different inter-row management. The result showed slight differences among the inter-row signals, which did not prevent the identification of inter-row management, thus indicating that field visits might not be mandatory.

Published: November 2023

Over the past 2 decades, cancer stem cells (CSCs) have been identified as the root cause of cancer occurrence, progression, chemoradioresistance, recurrence, and metastasis. Targeting CSCs is a novel therapeutic strategy for cancer management and treatment. Liver cancer (LC) is a malignant disease that can endanger human health. Studies are increasingly suggesting that changes in the liver mechanical microenvironment are a primary driver triggering the occurrence and development of liver cancer. In this review, we summarize current understanding of the roles of the liver mechano-microenvironment and liver cancer stem cells (LCSCs) in liver cancer progression. We also discuss the relationship between the mechanical heterogeneity of liver cancer tissues and LCSC recruitment and metastasis. Finally, we highlight potential mechanosensitive molecules in LCSCs and mechanotherapy in liver cancer. Understanding the roles and regulatory mechanisms of the mechano-microenvironment and LCSCs may provide fundamental insights into liver cancer progression and aid in further development of novel therapeutic strategies.

Se evaluó la concentración de zinc (Zn) y cobre (Cu) en 43 muestras de hígado y 77 de músculos del tiburón cabeza de pala (Sphyrna tiburo), como indicador del estado de salud de las costas de Campeche durante los años 2015, 2016 y 2019. Las comparaciones entre tejidos muestran consistentemente una menor concentración en el músculo (Zn = 19.8 ± 20.3 mg/kg; Cu = 0.67 ± 0.02 mg/kg) en comparación con el hígado (Zn = 31.0 ± 18.7 mg/kg; Cu = 3.56 ± 0.97 mg/kg). La concentración de Zn en el hígado fue influenciada por el sexo, ya que los niveles de Zn en el hígado de las hembras (34.8 ± 19.50 mg/kg) fue significativamente mayor que en el de los machos (24.5 ± 15.95 mg/kg). Se observó una disminución en la concentración de ambos metales a través de los años tanto en hígado (Zn 2015 = 32.5, 2016 = 31.8, 2019 = 14.7 y Cu 2015 = 3.36, 2016 = 3.89, 2019 = 3.18), como en músculo (Zn2015 = 15.0, 2016 =32.0, 2019 = 4.20 y Cu 2015 = 0.69, 2016 = 0.67, 2019 = 0.24). La concentración de Zn y Cu en músculo no sobrepasó los límites máximos permitidos por normas internacionales para consumo humano (Zn = 40 mg/kg, Cu = 10 mg/kg), por lo tanto, se puede concluir que S. tiburo como bioindicador de salud referente a estos dos oligoelementos, actualmente no representa un riesgo para la salud de los consumidores.

Nonlinear properties of zinc germanium diphosphide (ZGP) crystals enable their ap-plications in powerful mid-IR optical parametric oscillators and second-harmonic generators. This paper summarizes mechanisms of the laser induced damage (LID) in high-purity ZGP crystals under periodically pulsed nanosecond irradiation by a Ho3+:YAG laser at 2.1 μm. The ZGP samples were manufactured by “LOC” Ent., Tomsk, Russia, or Harbin Institute of Technology, China. The impact of processing techniques and the post-growing methods for polishing and anti-reflection coating on the LID threshold are discussed. The importance of the defect structure of the crystal lattice and the parameters of transparent coatings for increasing the LID threshold is discussed. The impact of the test laser parameters on the LID threshold is analyzed. The transient area near the LID threshold obtained using digital holography is ana-lyzed. Influence of the pre-damage processes on the optical parametric oscillations is reported. Prospects for improving ZGP crystals to further increase the LID threshold are discussed.

The contemporary landscape of education is witnessing a paradigm shift towards innovative instructional methods, with the flipped learning approach gaining considerable attention. The purpose of this research was to investigate the impact of the flipped learning approach on students' perception and acceptance throughout an entire semester in the 'Introduction to Programming with Java' course, using a research design with a quantitative approach, ultimately aiming to inform educational practice and advance our knowledge of innovative teaching methods in higher education. This study was conducted at a university with 174 students involved, divided into two groups, 87 students in the experimental group and 87 students in the control group. The data collected through the scales were analyzed by using descriptive and inferential statistical analysis techniques in statistical software. At the end of the measurements, the technology acceptance level and self-directed learning perceptions of engineering students who received education with flipped learning were high. The results suggest that educators should consider students' readiness for self-directed learning when implementing the flipped learning approach and focus on creating an environment that supports their autonomy and engagement. This research offers valuable guidance for instructors, curriculum designers, and educational policymakers seeking to enhance the effectiveness of flipped learning in higher education courses.

In livestock, brucellosis is mainly an asymptomatic disease except for abortion, therefore two serological tests are used for diagnosis as no single test is suitable. Abattoir samples enable a combination of culture, molecular and serological tests to detect brucellosis. This study assessed Brucella specific PCR (ITS-PCR) to detect brucellosis and to conduct molecular characterization of Brucella spp. isolated from PCR-positive livestock (n=565) slaughtered at abattoirs and the appropriate sample tissue(s). ITS-PCR detected Brucella DNA in 33.6% cattle, 14.5% sheep and 4.7% pig tissues. Impure Brucella cultures from PCR-positive tissues were 43.6% (44/94) cattle, 51.7% (15/29) sheep, and 50% (2/4) pigs with predominantly B. abortus identification with AMOS-PCR and low isolation of mixed B. abortus and B. melitensis in all species. In cattle 33% of isolates were from lymph nodes while in sheep 38.0% were from liver and kidney and only from tonsils in pigs (2/4). Brucella infections identified with AMOS-PCR were present in seropositive and mainly seronegative (75.6-100%) livestock with the potential to cause brucellosis during pregnancy or breeding. This study demonstrated the value of the polyphasic approach, especially with chronic infections and the potential risk of these asymptomatic animals.
An LCD Detection Method Based on the Simultaneous Automatic Generation of Samples and Masks Using Generative Adversarial Networks
Authors: Wu Hao , Liu Yulong , Xu Youzhi
Published: November 2023

When applying deep learning methods to detect micro defects on low-contrast LCD surfaces, there are challenges related to the imbalance in samples dataset, as well as the complexity and laboriousness of annotating and acquiring target image masks. In order to solve these problems, a method based on sample and mask auto-generation for deep generative network models is proposed. We first generate an augmented dataset of negative samples using a generative adversarial network(GAN), and then highlight the defect regions in these samples using the training method constructed by the GAN to generate masks for the defect images automatically. Experimental results shows the effectiveness of our proposed method, as it allows for the simultaneous generation of LCD image samples and their corresponding image masks. Through a comparative experiment on the deep learning method Mask R-CNN, we demonstrate that the automatically obtained image masks have high detection accuracy.
Rare Erath Elements: Their Geological Sources and the Potential of Organosulfonic Acids For Rare Earth Elements Leaching from Coal Ash and Process Optimization
Authors: Miadonye Adango , Amadu Mumuni
Published: November 2023

The orbital elactronic structure of Rare Earth Elements (REEs) contains many unpaired electrons which render them capable of storing large amount of magnetic energy in addition to being critical for hitech applications. Geological deposits are their conventional sources, and the current supply chain relies on production from these deposits. However, given their critical roles in the anticipated global energy transition, there is the need to explore other viable sources to supplement current and future supplies chains.
REEs occur in coal as accessory minerals and their concentration in coal ash to levels that rival those of geological deposits has been estab;ished by sophisticated analytical chemical methods. Conmventional hydrometallurgical processes rely on acid leaching, using tioxic mineral acids. Meanwhile, organosulfonic acids have pKa values that rival those of conventional minerals acid and can, therefore, be used in hydrometallurgy but their uses in this regard are not well documented in the literature. In this extensive review, we have covered geological sources of REEs exaustively in addition to showing the potential of organosulfonic acids as environmentally benign lixiviants for REEs extraction from coal ash. We have also shown how process optimization can be achieved using advance technologies while using organisulfonic acids. Moreover, we have shown current and future global market trends regarding the production of select organosulfonic acids, and the anticipated global increase in their production motivates the use of organosulfonic acids as viable lixiviants for REEs extraction from caol ash deposits.
