Published: February 2023

El Estado de Hidalgo se sitúa en México central y constituye un sitio privilegiado desde el punto de vista geológico, ya que confluyen en su territorio cuatro provincias geológicas diferentes: la porción sudoriental  del  Cinturón  Mexicano  de  Pliegues  y  Fallas,  que  cubre  aproximadamente  el  55%  del estado;  la  porción  oriental  de  la  Faja  Volcánica  Transmexicana,  que  abarca el  25%  del  territorio estatal; la terminación meridional del Miogeoclinal del Golfo de México, que comprende el 10% del estado  y  finalmente  la  terminación  sudoriental  de  la  Plataforma de  Valles-San  Luis  Potosí,  que conforma el 10% restante. Los depósitos minerales se distribuyen en todas las provincias geológicas que  confluyen  en  el  territorio  hidalguense,  pero  son  más  abundantes  en  el  Cinturón  Mexicano  de Pliegues  y  Fallas  y  en  la  Faja  Volcánica Transmexicana.  La  presencia  de  litologías  y  estructuras geológicas propicias, hace que existan depósitos tipológicamente diversos y de edades diferentes. Se hace  un  análisis  sucinto de  su  distribución.  El  territorio  hidalguense,  aunque  pequeño,  suministra diversos recursos (manganeso, plata, plomo, zinc, oro, cobre, arcillas, carbonato de calcio, cantera, pómez, mármol y cemento, entre otros), lo que explica el por qué, la minería ha estado en auge desde hace más de 500 años.

Authors: Gutiérrez Evelyn , Sánchez C.A. , Rodríguez José A. , Cruz Julián
Published: February 2023

Los nitrocompuestos se utilizan en productos comunes para la sociedad como disolventes, fumigantes, aditivos para gasolina, e incluso explosivos. Una ventaja de los nitrocompuestos es su propiedad de reducirse a su correspondiente amina con cantidades mínimas de intermediarios como hidroxilaminas y compuestos nitrosos mediante técnicas químicas y electroquímicas. En este proyecto se propone un método de análisis de 2-metil-5-nitroimidazol empleando voltamperometría diferencial de pulso y electrodos de trabajo de pasta de carbono modificados con nanopartículas de hierro. La modificación de los electrodos resulta positiva en la determinación del nitrocompuesto, lo que se ve traducido en un aumento en la sensibilidad analítica. La espontaneidad del mecanismo de reducción propuesto se comprobó mediante la construcción del perfil energía de la reacción calculado mediante la teoría de funcionales de la densidad.

Published: February 2023

La lixiviación metálica mediante un proceso de electrólisis, se manifiesta cuando en una reacción química se genera una corriente eléctrica o se establece un voltaje en sentido anódico, que estimule dicha reacción. El medio electrolítico, juega un papel importante desde el punto de vista industrial y ambiental. Es por ello que se busca el uso de electrolitos de baja concentración, a temperatura ambiente. La adecuada determinación de estos parámetros, puede ser trasladada a diferentes sistemas para su aprovechamiento. Tal es el caso de la recuperación de metales de alto interés económico como el Au y el Pt contenidos en desechos. Los diagramas de Pourbaix, han mostrado, en muchos trabajos, ser una herramienta muy útil en el planteamiento de las posibles reacciones involucradas en los procesos de oxidación y reducción. Sin embargo no sustituyen la cinética experimental. En el presente trabajo se estudia mediante diagramas de Pourbaix y voltamperometría cíclica la electrolixiviación de Au y Pt en un medio de ácido nítrico de baja concentración (pH 1.03). Para lo cual se empleó un sistema electroquímico de tres electrodos. Los resultados indican que la ventana de potencial para lograr la lixiviación de estos metales (Au y Pt) está entre 1.05V y 0.78V vs SCE y desde 0.8V a 1.2V vs SCE, respectivamente.

Published: February 2023

El iridio lixiviado proveniente de los materiales postconsumidos utilizados en la industria cerámica presenta alto valor económico y tecnológico. Es necesario para su fácil disponibilidad recuperarlo en forma metálica. La electrodeposición es un método que se ha mostrado como una alternativa viable para obtener de manera selectiva iridio sobre superficies utilizadas como cátodos. El presente trabajo muestra un estudio preliminar para el depósito de iridio en medio ácido sobre distintos substratos, con la finalidad de establecer las condiciones energéticas óptimas para su fácil disposición. La estrategia consiste en utilizar un electrolito estándar de iridio y armar una celda electroquímica, utilizando como electrodo de trabajo acero inoxidable (A316) y (A304), Titanio (Ti) y carbón vítreo (CV). Como contraelectrodos grafito (Gr) y titanio con óxido de rutenio (Ti-RuO2). Los resultados voltamperométricos para el electrólito sin iridio cuando se utilizan los tres electrodos de trabajo con los dos contraelectrodos presentan un comportamiento similar. Sin embargo, al incorporar iridio en el electrólito, los arreglos de celda con el contraelectrodo de (Ti-RuO2) no muestran una tendencia proporcional al tiempo de electrodepósito en la respuesta voltamperométrica cuando se fija el potencial catódico de inversión en el electrodo de trabajo. Por otra parte, los arreglos de celda con A316 y ambos contraelectrodos presentan un proceso de disolución correspondiente al acero en las respuestas voltamperométricas. Estos resultados indican que los electrodos de Ti, A304 y CV son sustratos viables en la recuperación de iridio en forma metálica.

Las nanopartículas de níquel han sido de gran interés en los últimos años por sus diversos campos de aplicación. En este trabajo se estudia la síntesis de nanopartículas de níquel metálico, cuando se emplea el proceso polyol. Mezclas de NiCl26H2O y NaOH disueltos en dietilenglicol (DEG) se sometieron a ebullición y agitación mecánica continua durante 2 h. Los polvos sintetizados fueron caracterizados mediante difracción de rayos X (DRX), refinamiento Rietveld, magnetometría de muestra vibrante (VSM) y microscopía electrónica de barrido de alta resolución (HR-MEB). La síntesis de las nanopartículas se produce a través de la acomplejación de los iones Ni2+ con DEG y posterior reducción química a baja temperatura (166°C). Los resultados demostraron la obtención exitosa de nanopartículas de Ni de ~50 nm de diámetro, constituida por una mezcla de estructuras cristalinas: hexagonal compacta (hcp) y cúbica centrada en las caras (fcc). Las nanopartículas mostraron un comportamiento ferromagnético a temperatura ambiente, con magnetización específica de saturación de ~17 emu/g y una coercitividad de 181Oe. Los valores de magnetización específica son muy inferiores a los del Ni-fcc puro, debido que el 65% de la muestra presenta fase hexagonal, la cual es antiferromagnética.

This research examines about “The Advantages of Dual Role Female Transmigration in Rural Areas”. The focus of the main stage in this study is to describe the lives of transmigration women who have a role in household/family life. The system owned by the transmigration program requires each transmigrant family to get 2 types of land, namely the main land area of 2 ha and the house and yard area of 0.5 ha. The process of working on two lands resulted in the division of work between men and women in transmigration families. Women, responsible for work in the domestic sector, gets a share of work on residential lands, where this land is usually planted with crops in the form of vegetables and seasonal crops that harvest quickly. The purpose of this research is to find out and analyze the life image related to female transmigration that are in two domains of life, both from domestic and public domains by using ethnographic methods with descriptive qualitative research. Based on the results of the study, it can be concluded that female transmigration in the Seruwey countryside are very different from other cases, where they get multiple benefits, other than the work in the domestic domain as a wife, and get the opportunity to manage 0.5 ah land for the yard of the house, female transmigrants also get the opportunity to work in oil palm plantations owned by local governments. It can be seen that women have skills and expertise in two domains of life, namely public and domestic, so that the role of transmigrated women in their lives gets multiple benefits to support family life.

Published: February 2023

Development communication as a branch of communication science has long been used by the world community as a reference in looking at relations and communication between the community and the government. In its classic form, development communication is limited to seeing the relationship between government and society as the object of development. Government communication activities, is an activity that describes the interaction between the community and the government in order to meet their demands and needs.The interaction between the two parties will lead to various communications in their respective ways, which can be formal, or informal and take the form of interpersonal communication, group communication, public communication and mass communication. The concept of development includes the role of communication, especially in designing messages specifically addressed to disadvantaged citizens. For this reason, the role of government development communication is very necessary in raising awareness, generating interest, and willingness to participate in the development process. In empowering oil palm farmers in Seuruway District, Aceh Tamiang Regency, the government needs to pay attention to the communication model used in conveying messages so that the expected effect is in line with expectations. This study tries to understand the communication model of village government development in empowering oil palm farmers. There are two communication models that are very dominant in village government, namely adaptive communication and accommodative communication. Adaptive communication can be seen from the village government's strategy of merging into the identity of residents as communication participants. While accommodative communication is in the form of collective actions of village officials in modifying the way of communicating according to the interests of village residents. Methodologically, this study uses a qualitative approach which will be conducted in the Seuruway District, Aceh Tamiang Regency.

The series of incidents of violence against children become a social fact that surrounds our lives. It appears in many forms, namely: physical violence, sexual violence, psychic violence, and social violence. The government has made various efforts to minimize cases of violence against children. However, a structural approach is not enough, it must be accompanied by a cultural approach. This article discusses how the cultural approach, in this case strengthening the pageu gampong system, can be used as a mitigation of the risk of violence against children. This study was conducted in North Aceh Regency using a qualitative approach. Data were collected using observation techniques, interviews, and literature studies. Socialization of the importance of the existence of the pageu gampong system must be carried out to all elements of society to raise collective consciousness in protecting the village from the influence of negative things. Efforts to reactivate the pageu gampong system encourage the formation of a community order that advises each other in kindness, takes care of each other community members, helps each other in terms of kindness, supervises each other suspicious things in the village environment, and can resolve disputes in the community indigenously.

Authors: Reza Fahlevi Muhammad , Zainal Suadi
Published: February 2023

The conflict for Aceh's independence from the Unitary State of the Republic of Indonesia ended peacefully through political negotiations in 2005. However, the issue of the rights of conflict victims has not been resolved until now. At the same time, the Truth and Reconciliation Commission (TRC) was established to handle it. This article aimed to explain the main causes of TRC's weakness in getting the attention and support of related parties, including the community, to strengthen the institution. This article uses a qualitative method with document data to explain the weaknesses of the Aceh TRC. Its findings show that the Aceh TRC could not encourage the government to make reparations for victims of the conflict, the main reason being that the formal regulatory status that underpins the institution's existence is too low.

The increasing demand for food, bioenergy and other agricultural products, as well as the intensification of climate change, pose special challenges for Central Asia’s agricultural sector in terms of implementing sustainable land management. Central Asia is a climate change hot spot. Adaptation measures of agricultural land use to climate change imply new trade-offs in terms of quality and provision of ecosystem services. Based on literature studies, this paper identifies examples of such trade-offs and presents possible solutions. The ecoregions of Central Asia show strong interdependencies. Therefore, a special focus has to be put on the transregional effects of the use of ecosystem services. Against the background of different concepts of sustainable development (ESS, SDG, Global Environmental Syndromes) integrative approaches for sustainable use and design of landscapes are necessary.
Hemofilia
Authors: Baiq nindya annisa putri  , Devi Rahmadona
Published: February 2023

Hemofilia merupakan penyakit turunan yang ditandai adanya pendarahan berat. Penyakit ini muncul sebagai perdarahan pasca trauma minor atau perdarahan spontan. Hemofilia disebabkan karena kelainan pada faktor protein koagulasi. Faktor VIII (FVIII) menyebabkan hemofilia A, dan faktor IX (FIX) menyebabkan hemofilia B. Hemofilia dapat didiagnosis melalui sekuensing gen dengan cara mengidentifikasi status pembawa. Pada saat prenatal, hemofila dapat dideteksi pada saat janin usia 12 minggu, tetapi memiliki resiko keguguran 0,5-1,0 %. Hemofilia diobati dengan dua pendekatan yakni pengelolaan pendarahan akut dan profilaksis. Pengobatan hemofilia harus memperhatikan dosis, jadwal, dan level target. Pengobatan hemofilia dapat mengunakan faktor VIII rekombinan dengan melibatkan inaktivasi virus dan teknologi skrining yang dinilai lebih aman. Komplikasi dapat terjadi karena kehadiran inhibitor penekan fungsi kerja faktor protein koagulasi, artropati hemofilik, dan pseudotumor pemicu pendarahan jaringan lunak yang berpotensi cedera organ dalam. Upaya pencegahan dilakukan dengan cara  menjauhkan penderita dari aktivitas pemicu luka pendarahan fisik, serta memastikan penderita memiliki sistem kekebalan normal untuk menerima vaksinasi rutin.

Published: February 2023

Abu limbah kayu merupakan salah satu bahan limbah yang dihasilkan industri pengolahan kayu atau sisa pembakaran batu bata merah yang banyak terdapat di Indonesia, sehingga abu limbah kayu (wood waste ash) relatif murah dan mudah mendapatkannya. Pemanfaatan abu limbah kayu sebagai bahan tambah campuran beton terutama pada beton normal belum banyak dilakukan, sehubungan dengan sifat kimia abu limbah kayu yang mengandung silica dan aluminat, maka perlu dilakukan penelitian tentang pengaruh penambahan abu limbah kayu terhadap kekuatan beton (kuat tekan dan modulus elastisitas). Pada penelitian ini kuat tekan rencana beton normal adalah 20 MPa. Selanjutnya pada campuran beton normal ditambahkan abu limbah kayu dengan presentase 0,  5, 10, 15 dan 20% dari berat semen. Abu limbah kayu yang dipakai merupakan hasil pembakaran batu bata merah. Benda uji  silinder diameter 150 mm dengan tinggi 300 mm dibuat untuk mengetahui kuat tekan dan modulus elastisitas. Uji kuat tekan dan modulus elastisitas dilakukan setelah benda uji mencapai umur 28, 60 dan 90 hari mengacu standar ASTM. Hasil penelitian menunjukkan bahwa penambahan abu limbah kayu pada campuran beton menyebabkan peningkatan kuat tekan dan modulus elastisitas dibandingkan dengan beton normal (tanpa abu limbah kayu). Kuat tekan dan modulus elastisitas maksimum tercapai pada umur 90 hari ini masing-masing sebesar 31,843 MPa dan 31389,086 Mpa atau meningkat sebesar 36,683%  dan 21,751% pada pada presentase abu limbah kayu 5%.
Transformação pedagógica

Todos nós sabemos que a educação é um assunto que recentemente vem sendo objeto de diversas dispu- tas ideológicas relacionadas à forma e ao conteúdo do ensino. Entretanto, parece haver um ponto de conflu- ência entre todos os que debatem a educação contemporânea: ela precisa mudar. Os modelos adotados em escolas e em universidades não refletem mais o tempo presente nem são capazes de extrair dos alunos toda a potência criativa que nós, humanos, temos em medidas distintas, em variados campos do saber.
O avanço tecnológico das últimas décadas mudou a equação do ensino ao evidenciar que não é mais o co- nhecimento que é escasso, mas a maneira de dar senti- do a ele. Antes da internet, as fontes de consulta eram muito menos numerosas e um dos papéis principais do professor era ser o transmissor das informações para os alunos. Hoje, esse papel se modificou e as instituições de ensino que não souberem harmonizar as atribuições de professores e alunos com a nova configuração social perderão boa parte de seu sentido.
Thiago Almeida nos oferece uma obra, ao mesmo tempo, teórica e prática. Explica a razão da necessida- de das mudanças e explica também o caminho a seguir. A transformação pedagógica, que requer um esforço conjunto e contínuo entre professores e gestores.

Objectives: To examine the effect of dietary supplements on diabetic risk progression, blood glucose level, and lipid profiles. Methods: A randomized, double-blind, placebo-controlled study was conducted at Rajavithi hospital, Thailand. Participants with prediabetes were randomly allocated to three arms of dietary supplements: placebo (PL) or curcumin plus fish oil and vitamin D (CFD), or curcumin plus fish oil (CF) for 24 weeks. Primary outcomes were the progression of glycemic status and the progression to overt diabetes at 24-week and 36-week follow-ups. Secondary outcomes were changes in glycemic profiles (fasting plasma glucose, 75 g OGTT 2-h plasma glucose or HbA1C), body weight, BMI and lipid profiles. Results: A total of forty-seven participants (PL, n = 16; CFD, n = 15; CF, n = 16) were included in the study. At the 24-week follow-up, the participants with worsening glycemic status in the intervention groups were lower, CFD, CF and Placebo, 14.29%, 13.33% and 31.25%, respectively. However, the primary outcome, progression of glycemic status, was statistically different, with p - value = 0.046 (p < 0.05) when excluding previous diabetes in the study. As well as the incidence of type 2 diabetes at 24-week follow-up was not statistically different between the three groups, 14.29%, 13.33%, and 12.5%, p - value = 0.699 (p < 0.05) in CFD, CF, PL group, respectively. The secondary outcomes also failed to demonstrate the effect of dietary supplements on blood glucose, lipid profiles, weight, BMI and blood chemistry. Conclusion: The combined dietary supplements which contained curcumin-fish oil-vitamin D, could lower the glycemic status progression in prediabetes at six months follow-up and were well-tolerated among the participants.

Introduction: The aim of this study is to develop the Taekwondo Performance Protocol (TPP), with which taekwondo-specific speed and quickness performance can be measured. Materials and Methods: The study was conducted with the participation of 79 active athletes that were at least at 1st gup level (red – black belt). At the development stage of the TPP, reliability calculations were made using the test-retest method. During the examination of the validity of TPP, Illinois agility, 20-meter sprint, vertical jump, and anaerobic power (Lewis) performances and the correlations between them were examined. In addition, TPP's effectiveness in distinguishing athletes of different performance levels was examined. Results: The results showed that TPP has a high level of reliability. It was also found that TPP was associated with Illinois agility, 20-m sprint, vertical jump, and anaerobic power (Lewis) characteristics at a low-to-medium level and had a high level of distinguishing ability for athletes of different performance levels. Conclusions: The results show that TPP is an economical, simple, reliable, and valid taekwondo-specific performance test.

The aim of this study is to define the uropathogenic bacterial resistance and to clarify how the COVID 19 pandemic has affected the development of bacterial resistance. Patients and methods: We conducted a retrospective analysis of the bacterial profile and antibiotic resistance status of the main isolates of uropathogens at the laboratory of microbiology at the military hospital Avicenne in Marrakech over the course of two time periods: the first was prior to COVID 19 (January 2019 to February 2020), and the second was one year later (January 2021 to February 2022). Results: In the first phase of the study, out of 4000 ECBU intended for the bacteriology lab, 581 met the criteria for a urinary tract infection. In the second phase of the study, out of 4692 ECBU requested, 590 samples were found to be positive, with a rate of incidence of 15%. For the two times, the Enterobacteries made up 80% of all the isolated bacteria. The total number of multiresistant bacteria (BMR) discovered on the ECBU's isolats during the course of the two study periods is 153, or 6.5% of the total isolats. Conclusion: This study made Escherichia coli the bacteria most implicated in the epidemiology of urogenital infections during the two periods. In the majority of cases, rates of resistance to various antibiotics increased during the COVID pandemic compared to the same time period two years earlier.

Background: Ectopic pregnancy is the most common cause of maternal mortality in the first trimester of pregnancy. Presentation is usually late especially in the developing countries of the world. Surgery is the preferred management modality compared to other management options because of challenges with monitoring in cases of un-ruptured ectopic pregnancies. The estimated global prevalence of ectopic pregnancy is 1-2%%. Aim: To determine the prevalence of ectopic pregnancy in surgical patients at the Rivers State University Teaching Hospital (RSUTH). Method: This study was a one-year retrospective research of Surgical (Surgery and Obstetrics/gynaecology departments) patients who had ectopic pregnancy at the RSUTH. The patients comprised of all the consecutive cases of the surgeries in these departments for the period under review. Permission for the study was obtained from the Head Department of obstetrics and gynaecology RSUTH. Structured profoma was used to extract information from patients’ case notes and analyzed using SPSS version 25. Result: The subjects for the study were 250, comprising of 98 (39.2%) males and 152 (60.8%) females. The age range was 22 years to 56 years. The mean age was 31 years of which 132 (52.8%) were obstetrics and gynaecological surgeries while 118 (47.2%) were non-gynaecological surgeries; 16 (6.4%) had ectopic pregnancy of which 12 (4.8%) were ruptured and 4 (1.6%) were unrutured. All the patients that had ectopic pregnancy had laparotomy with salpingectomy. Conclusion: The prevalence of ectopic pregnancy in surgical patients at the RSUTH was 6.4%. Majority of the patients present with ruptured ectopic pregnancy. All of the patients had surgical intervention (emergency laparotomy with salpingectomy).
