Authors: Silva Manuel , Silva João , Novo João , Oliveira Flávia , Carneiro Emília , Mourão Joana
Published: March 2022

Introduction: Due to the advances in anesthetics and surgery, ambulatory surgery plays an increasingly important role. This regimen, despite showing several advantages, still instills fear in patients. The aim of this was to evaluate the level of knowledge and the perspective of patients regarding ambulatory surgery.Material and Methods: A prospective study was carried out for two months in patients with pre-anesthetic consultation at a University Hospital Center. Demographic information, educational level, and previous ambulatory surgery were surveyed. Patients’ level of knowledge about surgery, satisfaction, and the perceived advantages and fears regarding this regimen were evaluated. The analysis was performed with SPSS, and p < 0.05 was considered statistically significant.Results: Two hundred and fifty-one patients were included. One hundred and twenty-eight (51%) patients disclosed having knowledge about ambulatory surgery. The main advantages perceived by patients were more peaceful recovery (44.7%), avoiding being surrounded by other patients (43.1%), and avoiding infection (37.2%). The main fears shown by patients were poor pain control (20.7%), having other health problems (13.1%), and poor control of nausea or vomiting (10%).Conclusion: Patients may benefit from being more informed about the ambulatory surgical regimen in order to decrease their fears and increase their acceptance of the regimen. Providing more information to patients may result in increased satisfaction with this regimen.

Aim: This study aimed to evaluate the effect of frozen storage on the physical properties of a silicone-based test food material, highly used to evaluate the masticatory performance in research settings. Methods: A total of 1,666 silicone cubes of Optosil Comfort® with 5.6-mm edges were shaped and stored at -18°C. The cubes were subsequently tested for flexural strength (maximum force, displacement, stress, and strain) before breaking (n = 136), changes in weight and size (n = 170), and masticatory performance (n = 1360) at eight timepoints: immediately after cube preparation (baseline, no freezing), and 1, 2, 3 and 4 weeks, and 2, 4 and 6 months after frozen storage. The cubes were thawed 8 h before each assessment. Results: The maximum force, stress, maximum displacement, and deformation values for the cubes were not affected by freezing (P > 0.05). At all of the time points, the cubes exhibited similar weight (P = 0.366) and size (identical values). The masticatory performance for the cubes also showed no differences from baseline through 6 months (P = 0.061). Conclusion: Freezing Optosil Comfort® silicone cubes did not alter the physical and mechanical properties of the material, being suitable to optimize the assessment of masticatory parameters for research purposes.

Published: March 2022

Universal health coverage is a global target included in the United Nations Sustainable Development Goals agenda for 2030. Healthcare in Brazil has universal coverage through the Unified Health System (SUS), which guarantees health as basic right to the Brazilian population. Considering the principles of SUS, public oral healthcare management is a huge challenge. Aim: To identify good management practices for quality care adopted by local public oral healthcare managers and teams around Brazil. Methods: This study was registered with PROSPERO (CRD42017051639). Five databases (PubMed, Embase, Web of Science, Scopus and Lilacs) as well as the reference lists and citations of the included publications were searched according to PRISMA guidelines. Results: A total of 30,895 references were initially found, which were evaluated according to the defined eligibility criteria. Twenty qualitative studies, eight surveys and two mixed-model studies were selected. The practices (codes) were organized into three main groups (families), and the Frequency of the Effect Size (FES) of each code was calculated. Among the 20 codes identified, the most relevant ones were: Diagnosis and Health Planning (FES=80%) and Family Health Strategy (FES=66,7). The Intensity of the Effect Size of each study was also calculated to demonstrate the individual contribution of each study to the conclusions. Conclusion: The evidence emerging from this review showed that healthcare diagnosis, planning, and performance based on the family health strategy principles were the most relevant practices adopted by public oral healthcare managers in Brazil. The widespread adoption of these practices could lead to improved oral healthcare provision and management in Brazil.

Abstrak: The incidence of CKD in the world is more than 500 million patients and up to 1.5 million patients need to undergo renal replacement therapy in the form of hemodialysis. Chronic kidney disease is inseparable from several complications, one of which is anemia. Confirmation of the diagnosis of anemia in CKD patients can be confirmed through various examinations such as the classic examination of serum ferritine levels, but ferritine is known to be involved in the inflammatory process that occurs in CKD. The aims of this study were to determine the relationship between the percentage of hypochromic erythrocytes and ferritine levels, to determine the average percentage of hypochromic erythrocytes and to determine the average ferritin level in CKD patients undergoing hemodiliasis at PKU Bantul Hospital. This study was conducted using a cross-sectional method involving 50 CKD patients at PKU Bantul Hospital. Blood samples were taken to check ferritine levels and hypochromic erythrocyte percentage. Data analysis was carried out with two types, univariate analysis and bivariate analysis which were carried out with the Spearman correlation test. Based on the results of univariate analysis, the median percentage of hypochromic erythrocytes of the research subjects was 0.95%. The median ferritine in research subjects was 105.5 ng/mL. based on the results of bivariate analysis, there was no significant relationship between the percentage of hypochromic erythrocytes and ferritine levels (p=0.130, r=-0.217). There was no significant relationship between the percentage of hypochromic erythrocytes and ferritine levels. Keywords: anemia; ferritine serum, chronic kidney disease, reticulocytes hemoglobin

Authors: Tran Binh Thuc , Tran Tuyen Ngoc , Tran Ai My Thi , Nguyen Giang Chau Dang , Nguyen Quynh Trang Thi
Published: March 2022

In this paper, the classical least square (CLS) method with molecular absorption spectrophotometric measurement was used to determine simultaneously of paracetamol (PAR), ibuprofen (IBU), and caffeine (CAF) in tablets. The absorbance spectra of the standard solutions and samples were measured over a wavelength from 220 to 300 nm with a 0.5 nm step. The concentration of PAR, IBU and CAF in the sample solutions were calculated by using a program called CLS-Excel written in Microsoft Excel 2016 and Visual Basic for Applications (VBA). The method and CLS-Excel program were tested on mixed standard laboratory samples with different PAR, IBU, and CAF concentration ratios, and they showed small errors and satisfying repeatability. An analytical procedure for tablets containing PAR, IBU, and CAF was developed. The reliability of the procedure was proved via the recovery and repeatability of the analysis results with an actual tablet sample and comparing the mean contents of active substances in the tablets obtained from the analytical procedure with the from the HPLC method. The procedure is simple with a reduced cost compared with the HPLC standard method.

Published: March 2022

The role of agroforestry systems in providing ecosystem services is very crucial. The most significant increase in carbon (C) storage is often achieved by moving from lower biomass land-use systems to tree-based systems like agroforestry (AF). However, estimation of carbon stocks in indigenous agroforestry systems of South-eastern Rift- valley landscapes, Ethiopia the data are scarce. The study was aimed to investigate the biomass, biomass carbon (BC), and soil organic carbon (SOC) stock of Enset based, Enset-Coffee based, and Coffee-Fruit tree-Enset based agroforestry systems. Comparison of SOC stock of agroforestry systems against their adjacent monocropping farms was also investigated. The study was conducted in three selected sites of the Dilla Zuria district of Gedeo zone. Twenty farms (total of 60) representative of each AF system were randomly selected, inventoried and biomass C stocks estimated. Ten adjacent mono-cropping farms which were related to each AF system were selected in a purposive manner for comparison of SOC stock. Inventory and soil sampling were employed in the 10×10 m farm plot. The mean aboveground biomass ranged from 81.1 t ha-1 to 255.9 t ha-1 and for belowground biomass from 26.9 t ha-1 to 72.2 t ha-1. The highest C stock was found in Coffee-Fruit tree-Enset based (233.3±81.0 t ha-1), and the lowest was in Coffee-Enset based agroforestry system (190.1±29.8 t ha-1). The result showed that SOC stocks were not statistically significant between the three AF systems, although they showed a significant difference in their BC stock. The AF systems' C stocks are substantially higher than those reported for tropical forests and other AF systems. The SOC of AF systems was significantly higher than the ones for the adjacent monocropped farms. Therefore, it is possible to deduce that AF systems are storing significant amount of C and contributing to climate change mitigation.

Following the rapid spread of COVID-19 across the globe, the intense response that was demanded of diagnostic centers and research laboratories prompted the use of numerous products and protocols for the management of SARS-CoV-2 specimens. In these settings, proper handling of such infectious specimen is necessary to ensure the safety of personnel and to reduce the risk of active transmission. Our aim was to evaluate the inactivation efficacy of different inactivating methods, notably from commercial lysis buffers available in diagnostic kits. Heat and sodium dodecyl sulfate detergent were also included in our investigations. A cell culture-based assay was used, and supported by molecular qRT-PCR detection, to show in vitro infectivity reduction after inactivation treatment. Overall, all the investigated methods were successful in inactivating SARS-CoV-2. Ten minutes of contact with the commercial buffers completely stopped in vitro SARS-CoV-2 infectivity. Fifteen minutes at 68°C and 30 minutes at 56°C as well as one hour with sodium dodecyl sulfate detergent at 2, 1, 0.5, and 0.1% yielded the same results. These findings demonstrate the reliability of these protocols with regards to biosafety. Inactivation by heat and sodium dodecyl sulfate detergent are rather simple and can be readily available methods for rendering an infectious SARS-CoV-2 specimen inactive, especially in settings where commercial buffers are not available.
Usefulness of Novel Atherogenic Lipid Indices for The Evaluation of Metabolic Status Leading to Coronary Heart Disease in A Real-World Survey of The Japanese Population

Published: March 2022

We evaluated the usefulness of the novel cholesterol-triglyceride subgroup (CTS) indices that potentially reflect the metabolic status regarding risk of coronary heart disease (CHD) using a retrospective longitudinal study of the Japanese general population. We recruited 12,373 individuals from the annual users of our healthcare center. Among them, the first onset of CHD was recorded in 131 individuals between April, 2014 and March, 2020. The multivariate Cox proportional hazards regression analyses for all normalized lipid indices revealed that the CTSqnt index showed a comparable hazard ratio for the CHD outcome to non-high-density lipoprotein cholesterol (nonHDL-c) and triglycerides. The HR of the CTSqlt index was significantly lower than for CTSqnt, but still comparable to that for low-density lipoprotein cholesterol (LDL-c). In comparison with the other indices, CTSqlt is more sensitive to risk increment while the index value increases. Linear regression analyses for the CTS indices and previously known lipid indices suggest that the CTSqnt and CTSqlt indices reflect the quantity of atherogenic lipoproteins and size of smaller and denser LDLs, respectively. Furthermore, the CTSqnt/HDL-c index can be used as a comprehensive risk indicator that may represent the status of lipid metabolism determined by the CTSqlt and CTSqnt indices and thus may be useful for screening. The CTS indices can be used to evaluate the metabolic status of individuals, which may increase the risk of future CHD.
Response Surface Optimisation of Polydimethylsiloxane (PDMS) on Borosilicate Glass and Stainless-Steel (SS316) to Increase Hydrophobicity

Published: March 2022

Particle deposition on the surface of the drying chamber poses the main drawback in the spray drying process, which reduces the product recovery and affects the quality of the product. In view of this, the potential application of chemical surface modification to produce a hydrophobic surface that reduces the powder adhesion (biofouling) on the wall of the drying chamber was investigated in this study. The hydrophobic Polydimethylsiloxane (PDMS) solution was used in the vertical dipping method at room temperature to determine the optimum coating parameters on borosilicate glass and stainless-steel substrates, which were used to mimick the wall surface of the drying chamber, to achieve highly hydrophobic surfaces. A single-factor experiment was used to define the range of the PDMS concentration and treatment duration using the Response Surface Methodology (RSM). The Central Composite Rotatable Design (CCRD) was used to study the effects of the concentration of the PDMS solution (X1, %) and the treatment duration (X2, hr) on the contact angle of the substrate (°), which reflected the hydrophobicity of the surface. A three-dimensional (3D) response surface was constructed to examine the influence of the PDMS concentration and treatment duration on the contact angle readings, which serve as an indicator of the surface's hydrophobic characteristic. Based on the optimisation study, the PDMS coating for the borosilicate glass achieved an optimum contact angle of 99.33° through the combination PDMS concentration: X1 = 1% (w/v) and treatment time X2 = 4.94 hr, while the PDMS coating for the stainless-steel substrate achieved an optimum contact angle of 98.31° with PDMS concentration: X1 = 1% (w/v) and treatment time X2 = 1 hr. Additionally, the infrared spectra identified several new peaks that appeared on the PDMS-treated surfaces, which represented the presence of Si-O-Si, Si-CH3, CH2, and CH3 functional groups for the substrates coated with PDMS. Furthermore, the surface morphology analysis using the Field Emission Scanning Electron Microscopy (FESEM) showed the presence of significant roughness and uniform nanostructure on the surface of PDMS-treated substrates, which indicated the reduction of wettability and the potential effect on unwanted biofouling on the spray drying chamber.

Authors: Hughes Phillip M. , Ostrout Tabitha L. , Pèrez Jolles Mónica , Thomas Kathleen C.
Published: March 2022

Objectives. To identify and describe differences in exposure to adverse childhood events (ACEs) by birth generation and lesbian, gay, bisexual, transgender, and queer plus (LGBTQ+) identity.

Methods. Using data from the 2019 Behavioral Risk Factor Surveillance System, we examined the odds of experiencing 4 or more ACEs for Generation X, millennials, and Generation Z relative to baby boomers (n = 56 262). We also explored differences between generations based on LGBTQ+ identity.

Results. The odds of experiencing 4 or more ACEs were higher for Generation X (odds ratio [OR] = 1.67; 95% confidence interval [CI] = 1.52, 1.83), millennials (OR = 2.12; 95% CI = 1.92, 2.35), and Generation Z (OR = 2.12; 95% CI = 1.79, 2.52) than for baby boomers. This disparity was amplified by LGBTQ+ identity (P = .016). The frequency of individual ACEs also varied by generation.

Conclusions. Exposure to 4 or more ACEs has increased for each generation since the baby boomers, and more so for the LGBTQ+ population. The ACEs experienced differ by generation.

Public Health Implications. Increasing ACE scores suggest that younger generations may have an increased risk of ACE-related health problems. Policies are needed to prevent ACE exposure and address the potential fallout from the ACEs that have seen the largest increases.

Published: March 2022

Objectives. To estimate differences in breastfeeding initiation (BFI) rates between African Americans and Black immigrants enrolled in the District of Columbia Special Supplemental Nutrition Program for Women, Infants and Children (WIC) between 2007 and 2019.

Methods. We used data collected as part of routine WIC program activities for first-time mothers (n = 38 142). Using multivariable logistic regression models, we identified determinants of BFI for African Americans, Black immigrants, non-Hispanic Whites, and Hispanics. To assess the trend in BFI over time, we calculated the average of the annual percentage changes.

Results. Compared with African Americans, Black immigrants had a 2.7-fold higher prevalence and Hispanics had a 5.8-fold higher prevalence of BFI. The average of the annual percentage changes was 0.85 for Hispanics, 3.44 for Black immigrants, 4.40 for Non-Hispanic Whites, and 4.40 for African Americans. African Americans had the only statistically significant change (P < .05). Disparities in BFI persisted over the study period, with African Americans demonstrating the lowest rates each year.

Conclusions. Significant differences exist in BFI between Black immigrants and African Americans. Combining African Americans and Black immigrants masks important differences, overestimates rates among African Americans, and may lead to missed opportunities for targeting interventions and policies to improve breastfeeding.

UNA Una experiencia de evaluación de las competencias digitales de los docentes en México
Authors: Lamschtein Susana
Published: March 2022

El trabajo presenta un marco de evaluación de las competencias digitales de los docentes que tuvo como objetivo orientar el diseño de intervenciones de un Programa de Fortalecimiento para el Aula @prende 2.0 de México. El instrumento de medida de esta competencia constó de dos partes. Una parte refirió a la adopción de la tecnología e indagó el uso de dispositivos y programas y su frecuencia. La otra, refirió a los usos en los procesos de enseñanza e indagó los contenidos en el corazón del marco DIGCOMPEDU de la Unión Europea. Se consideró que un uso poco sofisticado desde el punto de vista operativo puede ser oportuno y relevante desde el punto de vista educativo. Es decir, que un uso de las TIC puede ser estratégico en el proceso educativo sin que éste sea especializado o sofisticado desde el punto de vista técnico. Se discuten los resultados en este sentido, así como posibles sesgos derivados de la aplicación del instrumento, de la adecuación al contexto (válido y confiable hasta ahora en países europeos), o del momento de la medición (la pandemia). Para el análisis de las escalas de DIGCOMPEDU se siguió el procedimiento del Escalograma de Guttman.

La formación en ciudadanía de la juventud en México adquiere dimensiones primordiales en un momento histórico en el que se pretende transitar a un nuevo régimen político con valoraciones y principios contrarios a las que se habían impuesto bajo un régimen bipartidista, con fuerte arraigo en prácticas conservadoras y de corrupción. En este texto se analizan lasvaloraciones que tienen las y los jóvenes universitarios con respecto a la democracia y la política, sus acciones orientadas a la esfera pública y su uso de las redes sociales digitales, relacionado con temas ciudadanos.Los resultados muestran que el estudiantado percibe una democracia resquebrajada e inexistente; esta opinión divide a quienes consideran que este tipo de régimen es mejor a uno autoritario y a quienes señalan que sería mejor tener líderes duros. Asimismo, las acciones que lleva a cabo en la vida pública son mínimas y se concentran en la protección de los animales y en la firma de escritos de protesta.Finalmente, el estudiantado otorga gran valor a la participación de la mujer en la vida pública y política.Este escrito brinda diversas líneas de trabajo para futuras investigaciones que se centren en la formación ciudadana y participación política juvenil.
Más allá del humor: memes como prácticas discursivas en una comunidad de estudiantes universitarios
Authors: Martínez-Ortega Francisco
Published: March 2022

En este trabajo analizo la proliferación de memes en la cultura digital de la Universidad Nacional de Educación (UNAE, una universidad pública de Ecuador). Desde referentes de los Nuevos Estudios de Literacidad y las Nuevas Literacidades, realicé un acercamiento etnográfico a estas prácticas discursivas que implican la escritura en relación con otros medios para la producción de significado. Identifiqué la página de Facebook más exitosa que difunde memes en relación con la UNAE y recogí todos los memes del mes de octubre de 2019 (64 en total). Los categoricé inductivamente y encontré tres ejes generales para su descripción e interpretación: los temas tratados, los referentes o conocimientos que ponen en juego y las funciones implícitas además del humor. Describí en profundidad los 10 memes más exitosos (en términos de la interacción que detonaron) y brindé un panorama de los temas tratados (vivencias en la universidad, promoción de un modelo de estudiante y el paro nacional) y de sus funciones implícitas (informar, aliviar emociones, vincular a la comunidad, debatir política y reclutar miembros para la protesta). Finalmente, argumento que los memes cumplen funciones sociales importantes y podrían considerarse como un apoyo a la participación de los estudiantes universitarios en la cultura escrita y la sociedad.

Domba Batur merupakan salah satu sumber daya genetik unggul yang memiliki kontribusi penting bagi perkembangan peternakan di Kecamatan Batur, Kabupaten Banjarnegara, Jawa Tengah. Namun, potensi genetiknya belum dikelola secara optimal oleh peternak sehingga menyebabkan usaha domba Batur menjadi kurang ekonomis dan tidak kompetitif. Oleh karena itu, perlu ditinjau tata laksana pemeliharaan ternak, tingkat aksesibilitas pakan, dan kualitas pakan sebagai dasar menentukan langkah bijak ke depan dalam upaya
peningkatan produktivitas usaha tani menjadi lebih produktif dan efisien. Penelitian ini dilakukan dengan menggunakan metode purposive sampling di tiga kelompok peternak di Desa Batur dengan mengumpulkan data primer dan data sekunder. Data primer diperoleh dari wawancara, pengamatan langsung, dan analisis kualitas pakan di laboratorium (analisis proksimat dan kecernaan in vitro), sementara data sekunder diperoleh dari instansi terkait. Data dianalisis menggunakan analisis ragam (ANOVA) dan secara deskriptif. Hasil penelitian
menunjukkan bahwa tata kelola pemberian pakan di Desa Batur, Kecamatan Batur tergolong kriteria baik dan aksesibilitas pakan tergolong cukup terjangkau. Formulasi bahan pakan lokal dan teknologi pakan untuk menyediakan pakan berkualitas sepanjang tahun belum diterapkan oleh peternak. Skor kondisi tubuh dan bobot badan domba Batur pada tiga kelompok peternak tidak berbeda nyata (P > 0,05). Rataan bobot badan domba Batur betina pada umur <1–2 tahun dan 3–4 tahun sebesar 33,31–55,68 kg dan 52,81–55,68 kg, sementara bobot badan jantan sebesar 32,76–76,75 kg dan 100,40 kg. Hasil analisis proksimat menunjukkan kualitas nutrien hasil samping hortikultura (wortel, kacang panjang, dan kubis), rumput lapang, dan rumput odot yang bervariasi, akan tetapi nilai kecernaannya cenderung lebih tinggi pada hasil samping hortikultura. Hasil samping hortikultura tersebut dapat diformulasikan sebagai pakan ternak. Daya dukung dari hasil samping tanaman hortikultura di Kecamatan Batur diperkirakan memiliki kapasitas 1.085,16 satuan ternak sehingga masih dapat
ditingkatkan populasinya sebesar 1.608,21 satuan ternak. Hasil analisis proksimat dan kecernaan in vitro kacang panjang, wortel, dan kubis terindikasi lebih baik daripada rumput, di mana dapat digunakan sebagai tambahan pakan domba Batur hingga 40-100%.

Tujuan penelitian untuk mengevaluasi performa sumber daya genetik babi lokal (Sus scropa domesticus) yang meliputi aspek produksi, reproduksi, manajemen, dan persepsi budi daya. Pelaksanaan penelitian selama 6 bulan, yaitu Januari–Juni 2020 di Pulau Timor, Provinsi Nusa Tenggara Timur (NTT). Penentuan lokasi dilakukan secara purposive sampling berdasarkan kriteria ketersediaan populasi dan sampel, struktur umur ternak, dan status sosial budaya. Teknik pengambilan sampling menggunakan metode conveinance sampling baik terhadap responden peternak dan ternak babi sehingga penelitian ini terdiri atas 61 responden peternak dan 91 ekor babi lokal dengan kelas umur berbeda. Teknik memperoleh data menggunakan teknik wawancara, observasi, dan dokumentasi. Jenis data terdiri atas data primer dan sekunder. Analisis data menggunakan statistik Importance-Performance Analysis dan dijelaskan secara deskriptif. Hasil penelitian menunjukkan bahwa eksistensi sumber daya genetik babi lokal di Pulau Timor masih menunjukkan nilai yang rendah, baik dari aspek performa ternak (tidak efisien dengan nilai skor 365), manajemen budi daya (tidak efisien dengan nilai skor 291), sosial budaya (tidak efisien dengan nilai skor 359), dan lingkungan (terganggu dengan nilai skor 451). Kematian anak masih tinggi mencapai 25,6 ± 3,6%/periode kelahiran (KV 14,1%) dan interval kelahiran yang panjang yaitu rata-rata 10,4 ± 2,0 bulan (KV 19,0%). Kedua hal ini merupakan penghambat pertumbuhan dan perkembangan populasi babi lokal sehingga semakin menurun dari waktu ke waktu. Adanya intervensi kebijakan, teknologi, dan manajemen budi daya yang menyangkut aspek genetik, manajemen, dan sumber daya manusia dapat meningkatkan perbaikan performa dari babi lokal di Pulau Timor.

Abstract

Mutagen induced mutation in many explants and plant materials. These materials were determined mutant. The success of in vitro mutagenesis is influenced by the growing stadia of planting materials used during the mutagenesis process. Mutagenesis in the form of calluses has the potential to obtain solid mutants. The objectives of these studies were to find out materials explant for chemical induce mutation and in vitro media for callus production. Reagent Pink and Jaguar Pink leaf were used as materials. The experiment design was Complete Random Design, with seven treatment of MS (Murashige and Skoog) base medium and the addition of some growing regulatory subtances. Both of chrysanthemum varieties (Reagent Pink and Jaguar Pink) produced calli in all of tested media. The friable calli were obtained. There were same variation color of callus, e.g green, yellowish, and brownish. The variation of size and callus weight were also obtained eventhough it were not significantly different. M7 medium was recommended media for callus production, then it were used for induce mutation materials as based population.
Message Passing Interface (MPI) Parallelization of Iteratively Coupled Fluid Flow and Geomechanics Codes for the Simulation of System Behavior in Hydrate-Bearing Geologic Media. Part 2: Parallel Performance and Application

Published: March 2022

The reservoir geomechanics simulator (RGMS or RGM simulator), a geomechanics simulator based on the finite element method and parallelized using the Message Passing Interface (MPI), is developed in this work to model the stresses and deformations in subsurface systems. RGMS can be used standalone or coupled with flow and transport models. pTOUGH+HYDRATE (pT+H) V1.5, a parallel MPI-based version of the serial TOUGH+HYDRATE (T+H) V1.5 code that describes mass and heat flow in hydrate-bearing porous media, is also developed. Using the fixed-stress split iterative scheme, RGMS is coupled with the pT+H V1.5 to investigate the geomechanical responses associated with gas production from hydrate accumulations.

In the second paper of this series, the parallel performance of the codes is tested on the Texas A&M University Ada Linux cluster using up to 512 processes and on a Mac Pro computer with 12 processes. The investigated problems are:

Group 1: Geomechanical problems solved by RGMS in 2D Cartesian and cylindrical domains and a 3D problem, involving 4×106 and 3.375×106 elements, respectively;

Group 2: Realistic problems of gas production from hydrates using pT+H V1.5 in 2D and 3D systems with 2.45×105 and 3.6×106 elements, respectively;

Group 3: The 3D problems in Group 2 solved with the coupled RGMS-pT+H V1.5 simulator, fully accounting for geomechanics.

Two domain partitioning options are investigated on the Ada Linux cluster and the Mac Pro, and the code parallel performance is monitored. On the Ada Linux cluster using 512 processes, the simulation speedups (a) of RGMS are 218.89, 188.13, and 284.70 in the Group 1 problems, (b) of pT+H V1.5 are 174.25 and 341.67 in the Group 2 cases, and (c) of the coupled simulators are 134.97 and 331.80 in the Group 3 cases.

The results produced in this work show the necessity of using full geomechanics simulators in marine hydrate-related studies because of (a) the associated pronounced geomechanical effects on production and displacements and (b) the effectiveness of the parallel simulators developed in this study, which can be the only realistic option in these complex simulations of large multidimensional domains.
