Authors: Larabi Zina , Ghedamsi Kaci , Aouzelag Djamal , Nafa Fares
Published: July 2024

This paper presents two novel maximum power point tracking (MPPT) control strategies utilizing the gradient optimization algorithm to maximize the wind turbine's output power while minimizing the chattering effect resulting from intermittent control switching. In the first method, the gradient algorithm is integrated with sliding mode control (GSMC), and in the second technique, it is combined with adaptive fuzzy sliding mode control (GAFSMC). To assess the robustness and tracking capabilities of these techniques, numerical simulations were conducted under varying wind speed profiles. The results obtained demonstrate superior performance of the two newly developed methods when compared to classical SMC and fuzzy logic approaches.

Published: July 2024

The growth of renewable energy development and exploitation has been strong in recent years. The multisource pumping is considered as one of the most widely adopted solutions in rural (agricultural) areas. This paper presents a study of different components of the system, including both photovoltaic and wind generators with MPPT, batteries, and a motor-pump unit. It further explores sizing and energy management. The process of sizing involves determining the optimal component capacities to meet energy demands, taking into account variables such as energy source variability and load profiles. In parallel, energy management strategies are critical to balance energy supply and demand, mitigate intermittency issues, and extend the lifespan of energy storage components. This paper explores the sizing and energy management of a multi-source system comprising a photovoltaic generator, a wind turbine with MPPT methods, a battery storage and a motor pump to meet power requirements.

Authors: Xiong Hui-Lian , Li Zhi-Xin , Lu Xin , Lu Yan-Hua , Zhong Ping
Published: July 2024

BACKGROUND

Cerebral infarction is a local or extensive necrosis of brain tissue. Subsequently, the corresponding neurological deficits appear. The incidence of cerebrovascular diseases in China is increasing gradually. After the onset of cerebrovascular disease, the most common sequelae include movement disorders, language disorders, and cognitive dysfunction.

AIM

To investigate the effect of early refined nursing program on the prognosis of middle-aged and elderly patients with cerebral infarction combined with cognitive dysfunction.

METHODS

A retrospective study was conducted to divide 60 patients with cerebral infarction and cognitive impairment into an experimental group (n = 32) and a control group (n = 28). The experimental group received early intensive care every day, and the control group received daily routine care. The scores of the Mini-Mental State Examination (MMSE) and the Trail Making Test (TMT), as well as the latency and amplitude of the event-related potential P300, were used as main indicators to evaluate changes in cognitive function, and changes in BDNF, TGF-β, and GDNF expression were used as secondary indicators.

RESULTS

Both groups experienced notable enhancements in MMSE scores, with the experimental group demonstrating higher scores than the control group (experimental: 28.75 ± 2.31; control: 25.84 ± 2.87). Moreover, reductions in TMT-A and TMT-B scores were observed in both groups (experimental: TMT-A 52.36 ± 6.18, TMT-B 98.47 ± 10.23; control: TMT-A 61.48 ± 7.92, TMT-B 112.63 ± 12.55), with the experimental group displaying lower scores. P300 Latency decreased (experimental: 270.63 ms ± 14.28 ms; control: 285.72 ms ± 16.45 ms), while amplitude increased (experimental: 7.82 μV ± 1.05 μV; control: 6.35 μV ± 0.98 μV) significantly in both groups, with superior outcomes in the experimental cohort. Additionally, the levels of the growth factors BDNF, TGF-β1, and GDNF surged (experimental: BDNF 48.37 ng/mL ± 5.62 ng/mL, TGF-β1 52.14 pg/mL ± 4.28 pg/mL, GDNF 34.76 ng/mL ± 3.89 ng/mL; control: BDNF 42.58 ng/mL ± 4.73 ng/mL, TGF-β1 46.23 pg/mL ± 3.94 pg/mL, GDNF 30.25 ng/mL ± 2.98 ng/mL) in both groups, with higher levels in the experimental group.

CONCLUSION

For middle-aged and elderly patients with cerebral infarction and cognitive dysfunction, early refined nursing can significantly improve their cognitive function and prognosis.

Published: July 2024

BACKGROUND

The risks associated with negative doctor-patient relationships have seriously hindered the healthy development of medical and healthcare and aroused widespread concern in society. The number of public comments on doctor-patient relationship risk events reflects the degree to which the public pays attention to such events.

AIM

To explore public emotional differences, the intensity of comments, and the positions represented at different levels of doctor-patient disputes.

METHODS

Thirty incidents of doctor-patient disputes were collected from Weibo and TikTok, and 3655 related comments were extracted. The number of comment sentiment words was extracted, and the comment sentiment value was calculated. The Kruskal-Wallis H test was used to compare differences between each variable group at different levels of incidence. Spearman’s correlation analysis was used to examine associations between variables. Regression analysis was used to explore factors influencing scores of comments on incidents.

RESULTS

The study results showed that public comments on media reports of doctor-patient disputes at all levels are mainly dominated by “good” and “disgust” emotional states. There was a significant difference in the comment scores and the number of partial emotion words between comments on varying levels of severity of doctor-patient disputes. The comment score was positively correlated with the number of emotion words related to positive, good, and happy) and negatively correlated with the number of emotion words related to negative, anger, disgust, fear, and sadness.

CONCLUSION

The number of emotion words related to negative, anger, disgust, fear, and sadness directly influences comment scores, and the severity of the incident level indirectly influences comment scores.

LEGISLATIVE REGULATION OF CORRECTION OF REGISTRY ERRORS
Authors: Suslova Ellina , Petrovskaya Tamara
Published: July 2024

This article is devoted to the consideration of the concepts of “error” used in modern legislation. Information about land plots, which is contained in the Unified State Register (USR), of real estate is not complete and reliable, due to the inaccuracy of the information provided about the boundaries of the plot from the real estate cadastre. The main problem faced by the rights registration authority (RRA) is the discrepancy between the coordinates between the registered land plots and previously registered plots. This problem causes the boundaries of two areas to overlap or create empty space between them. These errors are most often identified by the PIU when transferring existing or entering new information about registered areas into the Unified State Register. Finding and correcting registry errors becomes mandatory, since these errors distort the characteristics of land plots, in particular their boundaries and area.
The purpose of the study is to analyze legislative regulation and study methods for identifying and correcting registry errors.
As a result of the analysis, it was established that cadastral work is becoming a key area of Russian cadastral activity, acting as an effective tool for correcting registry errors, updating information about land plots and mitigating the consequences of land disputes. If funding permits, expanding such work to most administrative units could potentially resolve a significant portion of existing disputes.

We investigate rifting during continental collision in southern Tibet by testing kinematic models for two classes of rifts: Tibetan rifts are defined as >150 km in length and crosscut the Lhasa Terrane, and Gangdese rifts are <150 km long and isolated within the high topography of the Gangdese Range. Discerning rift kinematics is a crucial step towards understanding rift behavior and evolution that has been historically limited. We evaluate spatiotemporal trends in fault displacement and extension onset in the Tangra Yumco (TYC) rift and several nearby Gangdese rifts and examine how contraction and rift exhumation relate to evolution of the Gangdese drainage divide. Igneous U-Pb and zircon (U-Th)/He (ZHe) results indicate rift footwall crystallization between ~59-49 Ma and cooling between ~60-4 Ma, respectively, with ZHe ages correlating with sample latitude. Samples from Gangdese latitudes (~29.4-29.8°N) yield predominantly Oligocene-early Miocene ages, whereas samples north of ~29.8°N yield both late Miocene-Pliocene ages and Paleocene-Eocene ages. Thermal history models indicate two-stage cooling, with initially slow cooling followed by accelerated cooling during late Miocene-Pliocene time. From spatial distributions of ZHe ages we interpret: (1) ~28-16 Ma ages from Gangdese latitudes reflect exhumation along contractional structures, (2) ~8-4 Ma ages reflect rift-related exhumation, and (3) ~60-48 Ma ages indicate these samples experienced lesser rift exhumation. Our data are consistent with a segment linkage evolution model for the TYC rift, with interactions between rifts and contractional structures likely influencing the evolution of topography and location of the Gangdese drainage divide since Miocene time
Optimization of Sugarcane Varieties for In vitro Regeneration and Multiplication through Tissue Culture
Authors: Khanum Plosha
Published: July 2024

Sugarcane is an important crop for sugar and bioenergy production and belongs to the family poaceae. Current sugarcane varieties have a highly complex and large genome, with 100-130 chromosomes. The demand for sugar, fiber, bagasse and molasses is increasing in Pakistan due to the rising population. Varieties of sugarcane (Saccharum officinarums L.) that are produced by breeding method take approximately 8-10 years, with the number of pests and diseases causing a decrease in cane yield. Improving the productivity of sugarcane varieties is a major challenge. Tissue culture is a way for quick multiplication of desired varieties and to develop disease free healthy plants.  Therefore, using high-yielding sugarcane varieties can help us in increasing production. This research aimed to optimize embryogenic callus for subsequent regeneration in sugarcane varieties, specifically CPF-251, HSF-240, and CP-77-400 to device micropropagation. Callus induction was initiated in four week culture of explant developed from spindle leaves by employing various concentrations of plant growth regulators (PGRs) such as Kinetin (0.2 mgL-1, 0.3 mgL-1, 0.4 mgL-1) and 2, 4-D (1.5 mgL-1, 2.5 mgL-1, 3.5 mgL-1) on Murashige and Skoog (MS) medium. Micro shoots emerged after three weeks of callus culture of media supplemented with differing concentrations of BAP (0.3 mgL-1, 0.4 mgL-1, and 0.5 mgL-1) on MS medium. After three weeks, roots developed, when the shooting plants were placed in the rooting medium containing varying concentrations of PGRs such as IBA (0.3 mgL-1 0.4 mgL-1, 0.5 mgL-1) and NAA (3.5 mgL-1, 4.5 mgL-1, 5.5 mgL-1) on MS medium. The most effective shoot growth of variety HSF-240 was obtained at MS + BAP 0.5 mgL-1 + IBA 0.5 mgL-1 + NAA 5.5 mgL-1 with 4.9 cm shoot length, 2.1 cm length of root and 8 numbers of roots. Similarly, for variety CP-77-400, optimal shoot growth was observed at MS + BAP 0.4 mgL-1 + IBA 0.4 mgL-1 + NAA 4.5 mgL-1, with a shoot length of 3.9 cm, root length of 2 cm, and 6 numbers of roots. For variety CPF-251, the most conducive conditions for shoot growth were at MS + BAP 0.3 mgL-1 + IBA 0.3 mgL-1 + NAA 3.5 mgL-1, resulting in a shoot length of 3.5 cm, root length of 1.7 cm, and 5 numbers of root formation. Plants developed through this study proved useful for producing high-yielding, high-sugar recovery cane of existing commercial varieties.

Cold storage and cryopreservation by encapsulation-dehydration of Cephalanthera rubra (L.) Rich., a threatened orchid species
Authors: Zargar Azad Mahdi , Kaviani Behzad , Sedaghathoor Shahram
Published: July 2024

Cephalanthera rubra (L.) Rich. is an orchid species in danger of extinction. In vitro conservation of this species has not been reported earlier. The aim of this study was to evaluate the effect of encapsulation-dehydration pretreatment on the survival percentage of cold preserved and cryopreserved shoot tips. Plant cryopreservation at ultra-low temperatures in liquid nitrogen (‒196°C) is an effective, low-cost, long-term, and proper conservation method for many plant species, particularly those included in the red list, such as orchids. The use of different pretreatments of plant germplasms to withstand against liquid nitrogen (LN) is a prerequisite of cryopreservation. In vitro preservation techniques, especially cold storage and cryopreservation, are two reliable methods to preserve genetic resources of orchids. The use of protective pretreatments against cold and freezing stress play an irrefutable role in maintaining the germination of germplasms after cold storage and cryopreservation. One of the most important and widely used pretreatments, especially for ornamental plants, such as orchids, is encapsulation-dehydration. The encapsulation-dehydration method was used as pretreatment for cold storage and cryopreservation of C. rubra (L.) Rich. germplasm. In situ-derived shoot tips were used as explants and encapsulated in sodium alginate-beads. Encapsulated shoot tips were treated in Murashige and Skoog liquid medium containing 0.75 M sucrose for 120 min and then dehydrated under a sterile air-flow of laminar hood cabinet for 120 min. Shoot tips were successfully cold preserved in a refrigerator at 4°C and cryopreserved by ultra-rapid freezing in LN and thawing in controlled environmental conditions with encapsulation–dehydration. The highest recovery level (82.33 and 83.66%) after cold storage and direct immersion in LN was obtained with the encapsulation technique based on 120 min dehydration, respectively. The lowest recovery level (37.66 and 33.66%) was recorded in cold-preserved and cryopreserved shoot tips without any pretreatments (control).

Reflexões sobre uma intervenção: diálogos entre psicanálise e ergologia
Authors: Santos Luciana Gelape dos , Gomes Júnior Admardo Bonifácio
Published: July 2024

Neste trabalho serão relatadas algumas reflexões teóricas sobre uma intervenção junto aos trabalhadores de uma mina subterrânea, realizada duas semanas após um acidente que vitimou fatalmente um dos trabalhadores. O objetivo da intervenção foi contribuir com a elaboração simbólica do ocorrido. Para tanto, partimos do pressuposto que um acidente de trabalho é sempre um lamentável infortúnio que, com maior ou menor frequência, pode desestabilizar o cotidiano de uma organização e de seus trabalhadores, e também proporcionar novos aprendizados. Tais ocorridos requerem sempre o cuidado de se ofertar aos sujeitos envolvidos espaços de fala que possibilitem o luto, a simbolização e a coletivização de saberes e valores na lida com os riscos do trabalho. Pautado por estas premissas realizamos quatro encontros de conversações com três coletivos, ocasião em que os trabalhadores foram encorajados a falar livremente não só sobre o ocorrido, mas também sobre os riscos e as saídas desenvolvidas no cotidiano da atividade. A escolha das conversações como metodologia decorre de nossa reflexão teórica a partir da articulação entre a psicanálise e a démarche ergológica.  Os encontros com os trabalhadores seguiram uma orientação lógica no uso do tempo: um instante de ver, um tempo de compreender e um momento de concluir. Nosso trabalho permitiu acolher algo das crenças, controvérsias e saberes investidos dos trabalhadores, trazendo-os ao diálogo com os saberes acadêmicos. Acreditamos que tais ações puderam contribuir com a troca de experiências e o desenvolvimento de atividades mais seguras e conscientes por parte dos trabalhadores da mina, fortalecendo o espaço da singularidade na dimensão do coletivo.

Objetivo: Identificar a produção científica sobre a percepção de autoestima para adultos diabéticos que usam insulina. Método: Trata-se de uma revisão integrativa da literatura. A coleta de dados foi realizada de junho a agosto de 2023, em cinco bases de dados: Biblioteca Virtual em Saúde (BVS); MEDLINE via PubMed; Web of Science; Scopus. Foram selecionados estudos nos idiomas português, inglês e espanhol, publicados entre 2019 e 2023. Resultados: Incluiu-se estudos em inglês; de delineamento transversal e quantitativo. Os principais aspectos foram o controle da glicemia, o impacto da diabetes nas questões socioemocionais e alterações no autoestigma. Conclusão: O diabetes mellitus tipo 2 interfere na área social, emocional e comportamental dos portadores da doença. A medicação é um fator crucial para o controle da glicemia. A insulina é percebida pelos pacientes como um fracasso no tratamento e existem várias barreiras que podem impactar diretamente na autoestima. A preservação da autoestima deve ser um dos objetivos para o controle do diabetes em pessoas que fazem uso de insulina. O profissional de saúde deve incluir a saúde mental em seu plano de ação e cuidados com esses pacientes.

O artigo teve por objetivo analisar como as representações sociais dos padrões de beleza atuais influenciam na autoestima da mulher idosa. Como método foi realizada uma pesquisa de campo descritiva, de caráter qualitativo. O público-alvo foram mulheres idosas que frequentam um grupo de estimulação cognitiva e socialização em gerontologia social de uma Universidade particular em São Luís-MA. Foram realizadas observações sistemáticas durante palestras intituladas “Autoimagem e Sexualidade de Pessoas Idosas”. Participaram, dezessete e vinte e quatro mulheres idosas, respectivamente do grupo de terça-feira e do grupo de sexta-feira. A partir da relação de interação entre observadores e as mulheres observadas, as falas foram categorizadas em três grandes eixos: 1. Imagem corporal frente ao envelhecimento; 2. Presença do etarismo nos padrões de beleza e 3. Importância do autocuidado para um envelhecimento saudável. A análise foi do tipo temática. Percebemos que apesar da aceitação do processo do envelhecimento no que se refere ao corpo e autoimagem, foram trazidas críticas ao etarismo presente na sociedade e na indústria anti envelhecimento, contrastando a população idosa geral do Brasil, devido à educação sexual voltada para o envelhecimento à qual as participantes têm acesso dentro do grupo.

Avaliar o efeito neuroprotetor do genótipo da ApoE2 na evolução da Doença de Alzheimer (DA). Trata-se de uma revisão integrativa da literatura, realizada nas bases de dados: BVS (Biblioteca Virtual em Saúde), PubMed, MEDLINE e LILACS, utilizando palavras chaves incluídas nos DeCS (Descritores em Ciências da Saúde): apoE2 e Alzheimer bem como sinônimos ou termos de entrada na língua inglesa, com base nos descritores estabelecidos no MeSH (Medical Subject Headings). Foram selecionados 12 artigos para revisão. A partir da leitura dos artigos foi observado a potencialidade clínica da presença do genótipo ApoE2 como fator neuroprotetor contra o declínio cognitivo relacionado à DA. Os estudos selecionados apresentam grande evidência científica para o entendimento da ação das isoformas da ApoE na regulação cognitiva da DA em seres humanos e em células de camundongos análogas às humanas. Portanto, é essencial analisar o efeito neuroprotetor da ApoE2 para desenvolver terapias eficazes contra a DA, considerando o sexo e o perfil dos portadores do alelo E2.

Published: July 2024

O hábito alimentar, que diz respeito ao padrão de escolhas alimentares que uma pessoa faz ao longo da vida, é dado por uma complexa teia resultante da interação entre fatores fisiológicos, ambientais e emocionais que tem origem na infância. O objetivo deste estudo foi investigar os principais fatores que influenciam no hábito alimentar infantil. Foi realizada uma revisão integrativa utilizando as bases de dados PubMed, SCOPUS (Elsevier) e Web of Science, adotando o operador lógico booleano “AND’’ e fazendo uso das seguintes palavras-chave, conforme os Descritores em Ciências da Saúde (DECS): ‘’Nutrição da criança’’ (child nutrition) AND ‘’comportamento alimentar’’ (Feeding Behavior), AND ‘’ Saúde da criança’’ (Child Health), AND ‘’Poder familiar’’ (Parenting), AND ‘’Preferências Alimentares’’ (Food preferences). Foram incluídos artigos publicados na íntegra, no período de 2018 a 2023, nos idiomas português, inglês ou espanhol, que respondesse à pergunta de pesquisa. Foram encontrados 164 artigos relacionados ao tema do estudo e, após um processo seletivo rigoroso, 7 trabalhos foram escolhidos com base nos critérios estabelecidos. Os artigos selecionados abordam pesquisas conduzidas em diversas localidades, incluindo países como Estados Unidos, Polônia, países da Europa, Sri Lanka, Canadá e China. Conclui-se que há uma rede complexa de fatores interconectados que podem influenciar o hábito alimentar infantil, tais como o ambiente familiar, a escola, a comunidade, o acesso a alimentos, a exposição à publicidade de alimentos e fatores socioeconômicos, educacionais e culturais, entre outros. A responsabilidade de criar um ambiente alimentar que promova escolhas saudáveis é compartilhada por todos.

Published: July 2024

Background: The literature review revealed few reports comparing dancers of different dance styles, especially in lower limb biomechanics and dynamic balance. This study aimed to compare the hip and knee ROM, hamstring muscle length, and dynamic balance between Polish folk dancers, ballroom dancers, and non-dancers. Methods: Nineteen Polish folk dancers (FD), fifteen ballroom dancers (BD), and seventeen physically inactive non-dancers (ND) took part in this observational study. The mean dancing experience of the dancers was 7.7 years. The research procedures included the use of the author’s questionnaire, assessment of lower limb range of motion (ROM) (goniometer), measurement of hamstring muscle length (the Active Knee Extension (AKE) Test), and dynamic balance assessment (the Y-Balance Test). Results: Analysis revealed significant differences in knee extension (p=0.001), hamstring muscle length (p <0.0001), and dynamic balance (p=0.02) between the groups. Conclusion: Due to the greater flexibility of the hamstring muscles in dancing groups, the knee hyperextension in ballroom dancers, and the knee limited extension in folk dancers, further research should be conducted to include the hamstring muscle peak force and the lumbopelvic complex assessment.
ENSAIO SOBRE A VERDADE, A PROVA, SUA VALORAÇÃO E VALORIZAÇÃO EM UM PROCESSO PENAL DEMOCRÁTI-CO
Authors: Teixeira André Gonçalves
Published: July 2024

A partir da adoção da Teoria Processual Neoinstitucionalista do Direito e do racionalismo crítico popperiano como marcos teóricos pretende-se rever a relação entre a verdade e a prova na produção do conhecimento em um processo penal democrático. Inicia-se o trabalho abordando as teorias da verdade como correspondência, como coerência, a pragmatista e a semântica, bem como sua relação com o conhecimento e a construção da ciência do Direito. Percebendo a incompatibilidade da dogmática com uma teoria do Direito adequada ao Estado Democrático contemporâneo, propõe-se a adoção da epistemologia quadripartite (técnica-ciência-teoria-crítica) do racionalismo crítico popperiano. A seguir é discutida a possibilidade de recepção de um conceito de verdade compatível com o processo penal em um Estado Democrático, mostra-se necessário rejeitar as correntes que defendem a verdade real e as que entendem pela ficção da verdade processual. A relação entre a prova como instituto jurídico e a verdade encaminhou a pesquisa para a principiologia da prova conforme a Teoria Processual Neoinstitucionalista do Direito aliada ao racionalismo crítico, abordando a necessidade de valoração e valorização da prova. Conclui-se que o processo de conhecimento não pode reproduzir o método empirista ou verificacionista de avaliação da prova resulta na necessidade de apoio do indutivismo. O método falsificacionista desenvolvido pelo racionalismo crítico popperiano esclarece que o propósito da investigação empírica é classificar uma hipótese como falsa, assim, a atividade probatória não é capaz de infirmar a verdade da narrativa da parte, mas apenas a sua falsidade. Conclui-se que a denúncia deve demarcar a hipótese acusatória, sendo necessário que a narrativa acusatória seja falseável, caso contrário será impossível a atividade probatória e o exercício do contraditório.
