Abstrak. Kualitas biochar sangat bergantung kepada bahan baku, lama pembakaran dan temperatur pembakaran. Kandungan senyawa kimia seperti selulosa, hemiselulosa dan lignin yang terdapat dalam bahan baku akan mempengaruhi biochar yang dihasilkan. Rendah dan tingginya temperatur pembakaran akan mempengaruhi sifat biochar (hidrofobik menjadi hidrofilik), mempengaruhi jumlah pori-pori pada biochar sehingga menghasilkan luas permukaan spesifik yang tinggi. Semakin tinggi luas permukaan spesifik pada biochar akan meningkatkan retensi air dan kapasitas tukar kation. Penelitian ini mengkaji kualitas sekam padi akibat pembakaran secara pirolisis dengan menggunakan dua dari tiga indikator kualitas biochar yaitu variasi temperatur pembakaran dan bahan baku. Penelitian ini dilaksanakan di Laboratorium Fisika Tanah dan Lingkungan Universitas Syiah Kuala. Alat yang digunakan dalam penelitian ini adalah chamber muffler dengan temperatur pembakaran yang diatur pada 400oC dan 800oC dengan waktu pemanasan masing-masing 4 jam. Hasil penelitian ini menunjukkan bahwa temperatur pembakaran dan bahan baku pembuatan biochar berpengaruh terhadap semua variabel karakteristik biochar yaitu rendemen, kadar air, kemampuan memegang air, pH, daya hantar listrik, zat menguap, kadar abu, karbon terikat. Rice Husk Biochar Characteristisc at two pyrolysis temperatureAbstract. The quality of biochar is highly dependent on the raw materials, duration of combustion and combustion temperature. The content of chemical compounds such as cellulose, hemicellulose and lignin contained in the raw materials will affect the biochar produced. Low and high combustion temperatures will affect the nature of the biochar (hydrophobic to hydrophilic), affecting the number of pores in the biochar resulting in a high specific surface area. The higher the specific surface area of the biochar, the higher the water retention and cation exchange capacity. This study examines the biochar quality of rice husks due to pyrolysis combustion using two of three indicators of biochar quality, namely variations in combustion temperature and raw materials. This research was conducted at the Laboratory of Soil and Environmental Physics, Syiah Kuala University. The tool used in this study is a chamber muffler with a combustion temperature set at 400oC and 800oC with a heating time of 4 hours each. The results of this study indicate that the combustion temperature and raw materials for biochar have an effect on all variables of biochar characteristics, namely yield, water content, water holding capacity, pH, electrical conductivity, volatile matter, ash content, and fixed carbon.

Nowadays, consumers tend to search for additional source of protein and energy for their dietary consumption, for instance from legumes and nuts. This trend is getting more common since the increase case of lactose intolerance. This study aims to study the effect of the formulation of materials consisting of a mixture of two or three types of nuts and the CMC (Carboxy Methyl Cellulose) on the quality characteristics of plant milk and consumer preferences towards the produced plant milk. The method used in this study was a factorial completely randomized design (FCRD). This study were used combination of two or three types of beans, namely soybeans (KK), peanuts (KT), green beans (KH). The first factor was formulation of raw materials (K1 = 50% KK: 50% KT: 0% KH, K2 = 50 % KK: 0% KT: 50% KH, K3 = 0% KK: 50% KT: 50% KH, and K4 = 33.3% KK: 33.3% KT: 33.3% KH). In addition, CMC was used as a stabilizer by treating different concentrations of CMC (C1 = 0.20% and C2 = 0.40%). Anova continued with DMRT0.05 determined that plant milk with the best treatment is K1C2 with the formulation of 50% peanut: 50% soybean and the addition of 0.4% CMC. The KIC2 treatment had values: protein content 3.87%, fat content 14.74%, pH 6.62, total dissolved solids 11.47oBrix. For consumer acceptance with RATA (Rate All That Apply) method, researchers found out that K1C2 has milky white color (89% of respondents), peanut aroma flavour (78% respondents), sweet (48%) and savory (37%) taste, thick and homogenous texture (44% respondents) with overall hedonic liking 3.11 or neutral. Protein content, fat content, and pH of vegetable milk meet the quality requirements of soy milk based on SNI No. 01-3830-1995.
La revista Atlántida (1963-1972)
Authors: Díaz Hernández Onésimo 
Published: February 2022

En 1963 aparecieron las revistas Cuadernos para el Diálogo, Revista de Occidente y Atlántida. Las dos primeras han sido objeto de libros y artículos, mientras la tercera apenas ha sido investigada. Este artículo examina qué se pretendía con esta revista, quiénes la hicieron posible y cuál era su línea de pensamiento, es decir, qué decía y cómo lo decía. La fuente principal es el archivo personal del promotor y director de Atlántida, Florentino Pérez-Embid, consultado en el Archivo General de la Universidad de Navarra. He seguido el hilo cronológico de los acontecimientos desde los primeros esbozos, la aparición de los primeros números hasta la crisis y desaparición de la publicación en 1972. Todo parece apuntar a que Atlántida se cerró por la falta de dedicación de tiempo de su director, ocupado con la dirección general de Bellas Artes y el rectorado de la Universidad Internacional Menéndez Pelayo.
Editorial - Cem anos de Paulo Freire
Authors: Campos Luana , Fachini Cristina , Carvalho Aline Vieira de 
Published: February 2022

No ano do centenário do educador Paulo Freire convidamos a todos arqueólogos e especialistas nas temáticas do patrimônio, memória e educação a colaborar com a construção de reflexões sobre as relações entre a Educação e Cultura Material, promovidas em ambientes escolares ou não, como práticas de liberdade. Paulo Freire foi recebido como subversivo por alguns setores da sociedade ao longo de toda sua vida como educador e, ainda nos dias de hoje, é rejeitado por determinados campos de poder. O que em sua obra e em nossas práticas pode tornar a educação tão perigosa? Qual o potencial de uma educação partilhada atrelada à cultura material? A educação como prática da liberdade seria capaz de romper a existência do “homem simples esmagado, diminuído e acomodado (...) tragicamente assustado, temendo a convivência autêntica e até duvidando de sua possibilidade” (Freire, 1967: 44)? Seria capaz de desnudar a sociedade como meio para desvendá-la e permitir uma compreensão ativa e atuante sobre os contextos políticos e históricos no qual nos inserimos (Freire, 1986: 15/17)? A educação como prática da liberdade mantém-se como um tema atual e urgente. Finalizando o dossiê, podemos abertamente afirmar que a proposta temática foi bem recebida pelos arqueólogos, educadores, historiadores, gestores públicos, entre outros especialistas no campo da memória, patrimônio e cultura material. No total, foram aprovados onze textos, entre artigos, entrevista e uma tradução inédita de uma entrevista dada por Paulo Freire, em Geneva, no ano de 1970. Em comum, os textos trazem como eixo central a reflexão ativa sobre cultura material, educação e liberdade. A temática é provocadora, e, claro, serve como uma plataforma para a construção de novos diálogos e práticas de ação. Nessa edição, portanto, você encontrará a seguinte estrutura:

Monte Carlo Simulation for Uncertainty Quantification of Probabilistic Original Hydrocarbon in Place Estimation a Convergence Study How Many Samples With a Particular Sampler are Needed

Abstract
It is not trivial to devise a universally accepted metric to assess the convergence of a Monte Carlo process. For the case of reservoir model, there is no "true" solution to compare against, so there is no choice but to reach statistical convergence if one wants to compute the expected value, standard deviation, quantiles, and so forth. Although we are lacking a reliable metric to assess convergence, looking at logarithmic plots can provide an estimate of how close one may be to a converged value. We call "eyeball test". The assertion that from looking at the log plot, the variation is reduced enough to confidently use the results the main objective of this work is to illustrate the potential issues of relying on non-converged Monte Carlo Simulation to estimate quantities such as the Original Hydrocarbon in place (OHIP) in the context of reservoir simulation. We will show that even in a limited-uncertainty setup, the quantiles, and the moments of OHIP as will also illustrate that the converged quantiles accurately represent the uncertainty of the system and can be used as a reduced order model for sensitivity studies.
The current work illustrates the convergence properties of a Monte Carlo Simulation used to quantify the geological uncertainty of probabilistic estimation of OHIP. We investigate the convergence behavior of Monte Carlo Simulation on 3D reservoirs model using
Two options for monitoring and stopping Monte Carlo Simulation : Post processing calculation (settlement of Statistical Moment)Automatic Realtime monitoring (Specific Error Bound)
The distributions of the moments and quantiles of the OHIP from10,000 realizations of a geological model are presented in the form of their Cumulative Density Functions. Stability of the computed moments is assessed by plotting the sample moments of the target variable evaluated at specific points as a function of the number of Monte Carlo Simulation performed. Our results suggest that the improvement in the quality of the results is significant and well worth the extra effort. For sensitivity studies, running large ensembles is still intractable but yields set of quantiles that can be used as a Reduced Order Model. The conclusions we draw are applicable to a wide range of similar 3D reservoir model. The sensitivity of Monte Carlo Simulation to the number of realizations used is often overlooked. Even though convergence studies are rare and convergence criteria hard to estimate, uncertainty quantification using Monte Carlo Simulation is an increasingly important part of static modeling workflows

Abstract
Background: This study aimed to develop and to validate dynamic predictive models for trauma-associated severe hemorrhage based on vital signs to register early warning and dynamic prediction of severe hemorrhage in trauma patients.Methods: The MIMIC-IV cohort was collected retrospectively. The inclusion criteria were trauma patients aged ≥16 years with complete clinical data. Heart rate, respiratory rate, systolic blood pressure, diastolic blood pressure, and peripheral oxygen saturation were extracted as predictive variables. Based on logistic regression, support vector machine, random forest, adaptive boosting, gated recurrent unit, and gated recurrent unit-d, predictive models for trauma-associated severe hemorrhage were developed and validated to dynamically predict whether severe hemorrhage will occur in trauma patients in the next 1 h/2 h/3 h. This study was based on the Trauma database of the General Hospital of the People's Liberation Army for external validation. The models were developed and validated using Python 3.8.5 software. SPSS.21 software was used for statistical analysis.Results: Of the 7522 trauma patients in the MIMIC-IV cohort, 283 (3.76%) had a severe hemorrhage. The area under the curve of the gated recurrent unit-d model was the best in the 1 h (0.946±0.029), 2 h (0.940±0.032), and 3 h groups (0.943±0.034), and there was no significant difference among the three groups. In the Trauma cohort, the area under the curve of the gated recurrent unit-d model also achieved the best performance in the 1 h (0.779±0.013), 2 h (0.780±0.008), and 3 h groups (0.778±0.009), and there was no significant difference among the three groups. When comparing the gated recurrent unit-d model with the traditional scoring systems, the gated recurrent unit-d model still has advantages. Moreover, we have developed a web-based predictive system to help clinicians use our models.Conclusions: This study developed and validated dynamic predictive models for trauma-associated severe hemorrhage based on vital signs to assist pre-hospital or in-hospital emergency personnel to make decisions, and the gated recurrent unit-d model performed best.Trial registration: The MIMIC-IV database was previously de-identified and reviewed by the institutional review board (IRB) of its host organization and determined to be exempted from subsequent IRB. We obtained the administrative permissions to use the database (Certification Number: 27959316) for our research, after completing the National Institutes of Health web-based training course: Protecting Human Research Participants. We were reviewed and approved by the Ethics Committee of Chinese PLA General Hospital to use the Trauma database. The ethical batch number is S2021-466-01. Moreover, the informed consent of subjects was waived by the Ethics Committee of Chinese PLA General Hospital.
