Authors: Silveira Neusa Vitória Valério , Zamboni Claydes de Quadros , Takahashi Mickiko Y.
Published: March 2024

Foram analisadas 103 amostras de pimenta do reino preta moída, comercializada na cidade de São Paulo e 15 da mesma pimenta, comercializada na cidade do Rio de Janeiro, com a finalidade de verificar fraudes e principalmente detectar semente de mamão moída que, conforme várias denúncias, estaria sendo adicionada a esse tipo de produto. Foram também estudadas amostras de pimenta do reino preta moída, de semente de mamão moída, e de misturas de pimenta do reino preta e semente de mamão moídas, preparadas no laboratório. As amostras foram submetidas a análise físico-química, exame microscópico e cromatografia em camada delgada. Não foi detectada a presença de semente de mamão nas amostras do comércio. Entretanto, o exame microscópico revelou que em 600/0 das amostras havia fraude, sendo identificados como adulterantes amidos de milho, trigo e mandioca, farinha de trigo, fubá, farinha de mandioca, pedúnculos da pimenta do reino, e matéria arenosa. Nas misturas preparadas foi possível observar maior sensibilidade ao exame microscópico em relação à cromatografia em camada delgada, pois este método somente detectou semente de mamão em misturas contendo 200/0 dessas sementes, enquanto que o exame microscópico detectou esse adulterante na proporção de 10/0. Foi sugerida a redução dos limites permitidos pela legislação em vigor do resíduo mineral fixo de 70/0 para 40/0, e do resíduo mineral fixo insolúvel em ácido clorídrico (1 +9), de 1,50/0 para 10/0. O extrato alcoólico estava abaixo dos limites exigidos pela legislação em 670/0 das amostras.

Examinaram-se, através de reação de fixação de complemento, os soros de 234 pacientes internados em hospital psiquiátrico localizado no município de Presidente Prudente, considerados de risco para infecção cisticercótica, além de 454 soros de gestantes procedentes da Região Administrativa de Santos e 397 soros de indivíduos considerados supostamente normais, procedentes da Região Administrativa de Presidente Prudente. O antígeno utilizado na reação de fixação de complemento foi obtido através de extração metílica, à temperatura ambiente, dos císticercos tratados com acetona. Consideraram-se positivas as reações em que ocorreu fixação de complemento a partir da diluição 1 :2. Dos 1.085 soros testados, 27 apresentaram atividade anticomplementar e 17 (1,6%) mostraram-se reagentes. Todavia, quando se consideraram, separadamente, os grupos procedentes de Santos, Presidente Prudente e os doentes mentais, percebe-se diferença significativa nos resultados: assim, os índices de freqüência foram, respectivamente, 0,88% e 1,00% para os indivíduos procedentes de Santos e Presidente Prudente e considerados supostamente normais e 3,8% para os doentes mentais. Os resultados indicam que não é desprezível a ocorrência de anticorpos anti-Cysticercus cellulosae em nosso meio, especialmente entre pacientes de hospitais psiquiátricos.

The Effects of Patient-specific Sequenced Osteopathic Manipulative Treatment by AGR on Quality of Life
Authors: Yang Yvonne , Stiles Edward , Kingery Jennifer
Published: March 2024

Background

Most osteopathic research has been technique, model, or protocol-driven which may not reflect actual clinical practice. Baseline health, mechanisms of injuries, and neuromusculoskeletal compensations are all unique per patient. An osteopathic research design that aligns with individualized patient care may better illustrate the role that OMM can play in health. Patient-specific, sequenced OMT by AGR (psOMT) addresses each patient's unique accrual of and response to somatic dysfunction throughout his or her body over time. To our knowledge, there have been no clinical studies looking at patient-specific, sequenced OMT by AGR and Quality of Life (QoL).

Objectives

To assess the effects of patient-specific, sequenced OMT (psOMT) in various Quality of Life areas.

Methods

A noncomparative study was conducted on all consenting patients of Pikeville Medical Center's OMT clinic from April 2021 to May 2022. Participants were evaluated and treated with patient-specific, sequenced OMT (psOMT) by Area of Greatest Restriction (AGR). Participants were given 2 modified PROMIS 29 Quality of Life surveys to assess nine domains of QoL.

Results

Participants who received psOMT showed statistically significant improvements in all 9 metrics of QoL (ρ<.001).

Conclusion

This study presents a paradigm for osteopathic medical research that honors each patient's unique accrual of and response to somatic dysfunction(SD) throughout their lifetime. This study suggests the following: 1) that SD may contribute to impairments in overall QoL, 2) that SD could represent a modifiable risk factor in general medical assessment, and therefore 3) that treatment of SD may contribute to improvements in QoL by relieving impairments to optimal physiologic function.
History of epidemics and preventive medicine in Algeria during the modern and contemporary period
Authors: Guedim Tayeb
Published: March 2024

Since ancient historical times, and up to the present day, humanity has been exposed to many infectious and dangerous diseases, which often led to death, and claimed thousands of human lives due to the spread of infection as a result of contact with infected people and carriers of the disease. When an epidemic spreads, or what is called a pandemic, since ancient times, man has tried and worked hard to find preventive solutions to ensure his safety and limit the spread of infection among members of society, including what is known as quarantine, health isolation, and social distancing, which is considered one of the most prominent and important primary preventive measures to confront infectious diseases. In this study, we will attempt to highlight the history of epidemics and preventive medicine in Algeria in the modern and contemporary period (the Ottoman period and during French colonialism), represented by smallpox, typhus, plague, and cholera, as well as the most important preventive measures taken to limit their spread, such as quarantine.

Published: March 2024

Ovaj rad bavi se analizom različitih vjerskih svečanosti i aktivnosti koje su upriličene za molitvenu pomoć vrhovnim poglavarima Katoličke crkve (papama) ili su pak organizirane na njihov poticaj, a održavale su se tijekom 19. te početkom 20. stoljeća na otoku Rabu. Riječ je o procesijama i hodočašćima te misnim slavljima. Jedno od hodočašća organizirano je 1872. godine u Kampor u crkvu sv. Bernardina Sijenskoga kada svi rapski vjernici žele uputiti Gospi molitve za mir u svijetu te za izbavljenje od nevolja »vatikanskoga zatočenika« pape Pija IX. Don Josip Gržetić Krasanin tom prigodom piše i pjesmu Ustanimo braćo pravo verna. Prisustvovanjem na takvim svečanostima rapska se zajednica povezivala s ostalim vjernicima Europe i svijeta te se identificirala s cjelokupnom zajednicom katolika pod vodstvom pape.
Classical PID Control of A Quadcopter UAV Under Variable Load Conditions
Authors: Zhao Haoyang
Published: March 2024

In recent years, the application of UAVs has become more and more extensive, resulting in a number of special operation UAVs. Quadrotor aerial robots have become one of the most popular vehicles at home and abroad because of their small size, light weight, simple structure, low cost, low requirements for takeoff and landing, and good maneuverability. UAVs are required to perform different tasks in the current complex environment, so variable loads are inevitable, and the stability of the UAV body is especially important when performing variable loads, and there are many ways to help and verify the attitude of the UAV during flight. In this paper, in order to more intuitively see the self-generated stability of the UAV under variable load conditions, the dynamics model of the UAV will be established first, and the simulation results show that the movement of the UAV has a very good stability. However, in the previous research, it is not possible to visualize the stability and flight state of the UAV when it is flying under variable load, this paper will make the UAV keep its own flight stability under two kinds of loads through the PID design model. At the same time, the function of the UAV's own mass change during flight is found, and the design function is used to show the stability curve of the UAV when it flies with its own changing mass. Through the final simulation and calculation, the experiment found that through the PID control, the flight state of the UAV when flying with variable load can be observed more intuitively, and the stability state of the UAV when flying can also be observed.

Authors: Yu Tingting , Cao Xuejun
Published: March 2024

In this study, a pH-response polyacrylate amphiphilic copolymer PMDB was used as the carrier to immobilize laccase from trametes versicolor. Under optimized conditions, the activity recovery of the immobilized laccase is 71.90%. The infrared spectroscopy results indicate laccase is successfully immobilized on the polymer PMDB. Also the properties of the immobilized laccase were studied. The recovery of the immobilized laccase is 96.8% (wt%) by adjusting the pH of the immobilized laccase solution to 3.3. And the immobilized laccase remains 78.13% of the initial activity after 5 batches reactions. Compare to the free laccase, the stabilities like thermal and storage stabilities of the immobilized laccase are enhanced. Moreover, the relative activity of immobilized laccase is nearly 110% when the concentration of urea in the solution is 0.02 M. The work in this manuscript can provide valuable references for enzyme immobilization.

How AR Technology is Changing Consumer Shopping Habits: from Traditional Retail to Virtual Fitting
Authors: Liu Ran , Balakrishnan Balamuralithara , Erni Marlina Saari
Published: March 2024

This paper examines the profound influence of augmented reality (AR) technology on consumer shopping behaviors, specifically the transition from conventional retail to virtual try-on encounters. The retail industry has undergone substantial transformation as a result of the emergence of e-commerce, which has brought forth both obstacles and prospects for retailers. Online shopping, although convenient, lacks the direct engagement and ability to physically examine products that are inherent in traditional retail. This has led to the development of augmented reality (AR) technologies to address this disparity. The study examines specific instances where augmented reality (AR) has been used in the context of custom furniture, virtual reality (VR) shopping experiences such as PaRUS, and improving accessibility for individuals with visual impairments.

Published: March 2024

Water is the source of life, an essential element in production, and the foundation of ecosystems. In the natural hydrological cycle, water that can be utilized by humans is referred to as water resources. Water resources form the basis for human survival and development, intimately connected to daily life, and concurrently represent a controlling factor in the ecological environment. It is well-known that the thermal power generation industry has consistently been a major consumer of water in the industrial sector, with substantial demands for water resources. Throughout the process of thermal power generation, water resources are extensively utilized for cooling, steam generation, waste heat discharge, and other processes. This large-scale utilization of water resources not only imposes pressure on local water resources but also leads to pollution of water environments and disruption of ecosystems.To address the challenges posed by the limited availability of water resources and environmental pollution, this paper explores the key technologies for optimizing water systems in thermal power plants. Through in-depth analyses of 3S water source optimization technology, ABFT biological treatment processes, recycled water utilization technology in the circulating cooling system, reclaimed water reuse technology, and the coal-fired "flue gas desulfurization" process, coupled with empirical studies of typical cases, the aim is to propose viable optimization solutions for water systems.

Effect of Cryogenic Time on Wear Resistance of M2 High Speed Steel
Authors: Li Qiang , Huo Xiaoyang
Published: March 2024

The wear resistance, residual austenite volume and carbon content in martensite of M2 steel were studied by means of universal vertical friction and wear testing machine, X-ray diffractometer (XRD), scanning electron microscope (SEM) and digital Rockwell hardness tester. The results show that a large number of fine carbide particles in M2 steel martensite are precipitated by cryogenic treatment and distributed uniformly and diffusely in the structure. With the increase of cryogenic time, the residual Austenite volume of M2 steel gradually decreases, while the Martensite volume increases, resulting in the wear resistance and Rockwell hardness increasing first and then decreasing. After 24 hours of cryogenic treatment of M2 steel, its wear resistance increased by 310%, hardness increased by 3.6%. Therefore, 24 hours is confirmed as the best cryogenic treatment time for the wear resistance and hardness of M2 steel.

El primer monumento a la educación: Benemérita Escuela Nacional de Maestros
Authors: Díaz Galván Raquel
Published: March 2024

En este trabajo se plantea un análisis histórico que contribuya en el conocimiento y divulgación de la última etapa de construcción de la Benemérita Escuela Nacional de Maestros, una de las instituciones educativas más importantes de México en materia de formación de docentes tanto por su antigüedad, su tradición, el tamaño de su comunidad escolar y, especialmente, por el patrimonio cultural con el que cuenta: arquitectura, escultura y pintura. Todo eso como parte del sentido de identidad normalista. Se trata de una escuela que desde hace más de ciento treinta y cinco años se ha especializado en la formación y profesionalización de los docentes de educación primaria, quienes han desarrollado su labor profesional con la niñez mexicana prácticamente en toda la nación. Su legado comenzó a finales del siglo XIX y todavía en el XXI se mantiene como una de las cinco normales más importantes del país. A lo anterior debe agregarse que, aún hoy, es la única institución de educación superior en México que también ha fungido como sede para una reunión de la Organización de las Naciones Unidas para la Educación, la Ciencia y la Cultura (UNESCO). En todo esto desempeñó un papel central quien en ese momento fungía como secretario de Educación Pública, Jaime Torres Bodet. ¿Cuándo ocurrió eso? ¿Cuáles fueron las causas que propiciaron esa reunión? ¿Quiénes fueron, además de Torres Bodet, los principales responsables de ello? ¿Cuáles sus principales consecuencias? Estas son algunas de las interrogantes que se revisarán en esta investigación.

Authors: Camacho Sandoval Salvador , Legaspi Lozano Mayela
Published: March 2024

El propósito de este artículo es analizar el debate contemporáneo sobre la educación de la sexualidad, tomando como referente los libros de texto gratuitos y los planes de estudio de educación Normal. Desde una perspectiva cualitativa y mediante un proceso analítico sintético, se examinan libros, artículos, ponencias de congresos y fuentes primarias. En los resultados se encuentra que los libros de texto, como instrumento de política educativa, han estado sujetos al rechazo de diversos actores políticos y sociales. Los planes de estudio para la educación normal han considerado la educación para la sexualidad de manera itinerante, pueden tener una perspectiva meramente biológica o una más integral. Se concluye que la educación de la sexualidad es un derecho de niñas, niños y adolescentes. Una posible ruta para su atención es fortalecer las capacidades de los formadores de docentes en el ámbito de la educación de la sexualidad, para que los futuros docentes que egresen de las escuelas Normales cuenten con las herramientas para acompañar a sus estudiantes.
