GR_EST: An OCTAVE/MATLAB Toolbox to Estimate Gutenberg–Richter Law Parameters and Their Uncertainties
Authors: Taroni Matteo , Selva Jacopo 
Published: September 2020

AbstractThe estimation of the earthquake size distribution parameters is one of the most important parts in any seismic hazard study. GR_EST toolbox is a source code written for OCTAVE/MATLAB (Eaton et al., 2019; MATLAB, 2019) that allows estimating these parameters in a proper way, including the estimation of the associated uncertainties. The toolbox contains functions to make the parameter estimation both for instrumental and historical seismic catalogs, also considering time-varying completeness for magnitudes. Different functional forms for the magnitude–frequency distribution and different strategies for the estimation of its parameters and relative uncertainty are included. To guide the seismologists into the use of this toolbox, a set of complete examples is provided, to be used as “how to” use cases.

AbstractThe populace of Los Angeles, California, was startled by shaking from the M 7.1 earthquake that struck the city of Ridgecrest located 200 km to the north on 6 July 2019. Although the earthquake did not cause damage in Los Angeles, the experience in high-rise buildings was frightening in contrast to the shaking felt in short buildings. Observations from 560 ground-level accelerometers reveal large variations in shaking in the Los Angeles basin that occurred for more than 2 min. The observations come from the spatially dense Community Seismic Network (CSN), combined with the sparser Southern California Seismic Network and California Strong Motion Instrumentation Program networks. Site amplification factors for periods of 1, 3, 6, and 8 s are computed as the ratio of each station’s response spectral values combined for the two horizontal directions, relative to the average of three bedrock sites. Spatially coherent behavior in site amplification emerges for periods ≥3  s, and the maximum calculated site amplifications are the largest, by factors of 7, 10, and 8, respectively, for 3, 6, and 8 s periods. The dense CSN observations show that the long-period amplification is clearly, but only partially, correlated with the depth to basement. Sites with the largest amplifications for the long periods (≥3  s) are not close to the deepest portion of the basin. At 6 and 8 s periods, the maximum amplifications occur in the western part of the Los Angeles basin and in the south-central San Fernando Valley sedimentary basin. The observations suggest that the excitation of a hypothetical high-rise located in an area characterized by the largest site amplifications could be four times larger than in a downtown Los Angeles location.
Association of Subpubic Angle Measurement with Age and Gender in a Group of Adult Sudanese Patients
Authors: Awad Khalid , Mohammed Rabab 
Published: September 2020

Background: The measurement of the subpubic angle (SPA) has been used for determining gender with a high degree of accuracy in various ethnic groups. This measurement can also be helpful in forensic and physical anthropology. The aim of this study was to compare the SPA in different adult age groups (males and females) and to use the SPA to estimate the demarking point (DP) for the determination of gender.
Methods: This study included 158 subjects – 59 male and 99 female. The SPA was measured electronically using antero-posterior pelvis X-rays. Measurements were taken retrospectively using the Picture Archiving and Communication System. SPA measurements were compared between the male and female participants in different adult age groups. To determine the gender, the DP was calculated from the means of SPA in male and female participants.
Results: A comparison of the means of SPA between males and females showed that females (134.94 ± 15.33º) had wider SPA than males (105.88 ± 10.33) with a significant difference (P = 0.012). While a DP > 126.5 is most likely indicative of a female pelvis, a DP < 104.3 is indicative of a male pelvis. The accuracy levels based on the measured DP of participants in this study were 45.8% and 69.7% for males and females, respectively. Besides, with regards to age, the mean values for different age groups in males and females were statistically insignificant (P-values were 0.21 and 0.75, respectively).
Conclusions: According to the obtained results, the variations in the measurements of the SPA from pelvic X-rays can be used to determine gender. The calculated SPA range and DP were found to predict female gender with higher accuracy. Age was not associated with any notable differences in SPA measurements.

The best time of completion thyroidectomy in differentiated thyroid carcinoma: A review of literature
Authors: O. Mirghani, MD, MSc Hyder 
Published: September 2020

Background: Completion thyroidectomy is performed for high-risk differentiated thyroid carcinoma; however, the timing of the completion thyroidectomy is a matter of controversy. The current review aimed to assess the best time for completion thyroidectomy in patients with differentiated thyroid carcinoma.
Methods: An electronic search was conducted in various databases, such as Pub Med, Google Scholar, Scopus, and Medline, for relevant articles assessing the timing of completion thyroidectomy from the first published article to October 2019. Keywords, “completion thyroidectomy” and “timing” were used. The search was limited to articles published in the English language. Among the 190 articles retrieved, only 11 fulfilled the inclusion criteria.
Results: Of the 11 articles included, two were from Europe, one from Africa, one from Australia, and seven from Asia, and all were retrospective studies with the mean duration of studies being 12.71 ± 12.31 years. Five studies (45.5%) showed no effect of timing on the outcomes, two (18.2%) recommended both early and late operation, another two (18.2%) concluded that late operation is better, one (9.1%) found that early surgery is better, while one study (9.1%) stated that the timing of operation should be based on the category of the patient.
Conclusions: The results were mixed with some studies recommending late completion thyroidectomy, some observing that both early and late thyroidectomy are safe, while some finding no effect of time on the completion thyroidectomy. Well-designed controlled trials will resolve the issue.
Keywords: early completion thyroidectomy, late thyroidectomy, timing
Organicismo: morfología y materialidad como expresión comunicante en un espacio arquitectónico
Authors: Viveros Baez Ricardo José 
Published: September 2020

A partir de la arquitectura orgánica, entendida como una filosofía que promueve la armonía entre el hábitat humano y el entorno natural, se marca un quiebre sustancial con las composiciones formales tradicionales, y desde donde se aprovechó las propiedades de nuevos materiales y nuevas técnicas productivas. Este movimiento surge en oposición al racionalismo o funcionalismo, manifestándose en las primeras décadas del siglo XX y con ello se compromete el diseño de objetos y particularmente el diseño de mobiliario de interiores, basado en estructuras orgánicas, y de una forma de diseño que abre fronteras entre lo material y lo sentimental, cuya fuente de vivencias es la naturaleza.
La gran diversidad de soluciones -presentes en nuestro entorno natural- a problemas estructurales, en términos de energía y funcionalidad, ya han sido probados durante millones de años, y en ella podemos encontrar todo tipo de patrones y combinaciones de formas, colores y texturas que son el fundamento del diseño orgánico como una fuente inagotable de inspiración para diseñadores. Se constituye como una poderosa herramienta y fuente de inspiración sin fin, unida por los principios de la vida misma, tratando de imitar las formas, texturas o funciones de los organismos vivos para alcanzar soluciones de diseño óptimas.
En el presente trabajo se muestra un breve recorrido por los inicios del diseño orgánico, particularmente el diseño de mobiliario, recorriendo algunos clásicos representativos del diseño nórdico y estadounidense, desde la relación forma-materia.
Luego se reconoce uno de los principales exponentes del diseño orgánico: Alvar Aalto, arquitecto y diseñador finlandés, a través de dos de sus creaciones más icónicas; el proyecto arquitectónico Sanatorio de Paimio y la silla 41. La idea central del Sanatorio, era un edificio que favoreciera la curación y rehabilitación de enfermos de tuberculosis. Este proyecto fue concebido integralmente, lo que le llevó a la definición de un mobiliario específico. Producto de ello es la silla número 41, más tarde conocida como silla Paimio de la cual se da cuenta de sus características morfológicas y de materialidad. Finalmente se establece una relación donde el objeto se conecta visual y funcionalmente con el contexto de su emplazamiento interior del conjunto arquitectónico.

Published: September 2020

La generación de conocimiento en sistemas agroforestales con café requiere de una oferta importante de especies arbóreas que regulen la luminosidad y sean amigables con la biodiversidad y el suelo, funciones que cumple Albizia carbonaria. En una zona cafetera del departamento de Nariño se sembraron 50 plantas para evaluar biomasa seca total (BT) y captura de carbono (Ca) en la especie, a partir de modelos alométricos. Durante 600 días después de la siembra, se hicieron mediciones bimensuales en cinco plantas de altura de planta (AP), diámetro basal del tallo (DIA), diámetro normalizado a altura de pecho (DAP), número de hojas (NH) y número de ramas (NR). Mediante el método destructivo se determinó el peso fresco de raíces, tallos y hojas, para obtener la BT. El Ca se consiguió del producto BTx0,5. Además, se calcularon la tasa relativa (TRC) y absoluta de crecimiento (TAC). A excepción de NHvsTRC, el análisis de correlación indicó alta asociación entre todas las variables estimadas. El NH y el DIA se ajustaron al modelo lineal, la AP al modelo cuadrático, la TRC a un polinomio de tercer grado, con bajas calificaciones en el coeficiente de determinación, cuadrado medio del error, AIC y BIC. La BT y el Ca se explican a través del DIA y AP, mediante los modelos Husch y Shumacher-Hall, caracterizados por sus bajos valores de cuadrado medio del error, AIC y BIC y alto coeficiente de determinación. El tallo fue la fuente de la BT con porcentajes superiores al 50 %.

Published: September 2020

Peningkatan kualitas pada bidang Administrasi Umum dan Keuangan Universitas Negeri Jakarta (UNJ) merupakan salah satu cara untuk mewujudkan target dari Rencana Strategis (Renstra) UNJ guna menghadapi tantangan perkembangan dunia pendidikan di masa depan dan tuntutan dari stakeholders. Peningkatan kualitas dilakukan dengan cara mengevaluasi capaian target dari masing-masing rencana kerja pada Bidang Administrasi Umum dan Keuangan, khususnya perihal kualitas Sumber Daya Manusia, serta pengelolaan Sarana dan Prasarana di UNJ.
Penelitian dilakukan di lingkungan PR II UNJ yang meliputi unit kerja BAUK dan BAPSI berdasarkan gagasan Nee mengenai new sociology economics institutionalism. Gagasan tersebut membagi mekanisme integrasi hubungan formal dan informal pada setiap level kausal, yakni pada tataran mikro (individu) yang dijelaskan sebagai sistem jaringan elemen dalam unit kerja pada penelitian, tataran messo (kelompok ataupun organisasi) yang dijelaskan sebagai bentuk tata kelola unit kerja pada penelitian, dan tataran makro berupa lingkungan kebijakan (policy environment) yang dijelaskan sebagai proses perumusan implementasi kebijakan unit kerja oleh pihak rektorat dalam penelitian. Penelitian dilaksanakan melalui 7 tahapan sesuai pendekatan metode Soft System Methodology (SSM).
Hasil penelitian ini menunjukkan bahwa pada level makro, dalam melaksanakan tugasnya unit kerja bidang administrasi umum dan keuangan selalu melibatkan setiap elemen yang terdapat pada unit kerja ini sesuai dengan kebutuhan dari proses belajar mengajar dari masing-masing fakultas. Proses perumusan kebijakan yang dilakukan sudah sesuai dengan pendekatan Renstra, yakni harus sistemik, imajinatif, dan tidak terikat oleh kontinuetas kegiatan yang telah lalu. Sedangkan, pada level messo, dalam pelaksanaan proses tata kelola, para staf dalam unit ini masih mendapatkan masalah. Masalah yang terjadi terkait masalah akuntabilitas dan keterampilan Sumber Daya Manusia. Pada level mikro, setiap elemen memiliki tata perilaku, norma, kebiasaan, peraturan formal maupun informal dalam melakukan eksekusi setiap rumusan kebijakan yang telah dibuat oleh unit kerja ini. Namun, masih ditemukan masalah sistem jaringan yang menyulitkan bagi setiap elemen pada unit kerja ini.
Hasil penelitian juga menunjukkan bahwa bentuk transformasi yang telah dilakukan oleh pihak Universitas Negeri Jakarta adalah dengan melakukan penguatan kelembagaan dalam hal tata kelola setiap unit kerja yang ada di universitas, termasuk dalam unit kerja bidang administrasi umum dan keuangan. Proses penguatan yang dilakukan adalah dengan melakukan perubahan bentuk tata kelola setiap unit kerja. Penguatan ini dilakukan dengan cara merubah standar tata kelola berdasarkan pada rancangan tata kerja dan organisasi badan layanan umum.
