Quran Literacy for Students with Special Needs
Authors: Aly Hery Noer , Bustomi Bustomi 
Published: January 2023

The study is aimed to investigate the implementation of teaching Quran literacy for students with disabilities. It applied qualitative. Data were collected using observation and interviews with teachers of Iqro (Quran for beginner). The participants of the study were students with disabilities studying in schools for special need inÂ Bengkulu and Ciamis regency West Java Indonesia. The schools include MI (Madrasah Ibtidaiyyah/Islamic Elementary School) Mutiara Asyifa, Abdurrahamn Bin Auf, SDLB (Sekolah Dasar Luar Biasa/Elementary School for Special Need) Islam Amal Mulya, SLB (Sekolah Luar Biasa/School for Special Need) Baiturrahman Cisaga, and SLB Albarokah Baregbeg. The result showed that the schools have provided minimum service for teaching and learning Quran/Iqro for students with disabilities. There are two factors causing the situation; the scarcity of PAI (Pendidikan Agama Islam/Islamic Religious Education) teachers in the schools and the absence of reliable Quran reading methods. The teachers background are language teachers who had no experience and competence for Islamic religious education. In addition, the learning method for Iqro is similar to the BISINDO (Bahasa Isyarat Indonesia/Indonesian Sign Language) method for reading by sign language. This study suggests that PTKIN (State Islamic Higher Education) offering PAI to provide a program for Quran reading and writing courses for students with disabilities.

Published: January 2023

Interactive learning media integrated with technology are needed to facilitate the explanation of abstract material, including elemental chemistry. The study aims to analyze the profile of interactive learning media-based digital literacy needs on elemental chemistry concepts in high school students. The research uses a descriptive qualitative research method. The subjects of this study consisted of chemistry teachers and high school students from four sub-districts in Trenggalek Regency. Based on perspective of teachers and students, they need learning media that can help explain abstract material to be more communicative and interactive to increase learning effectiveness. The results of questionnaire answers show the application of interactive digital learning media based digital literacy from the teachers and students are 39% and 37%, respectively. The percentage shows that digital literacy-based learning media is still lacking. Furthermore, interactive learning media based on digital literacy could be developed to fulfill a need using specific criteria.

El objetivo de este trabajo es mostrar las utilidades del programa informático ModestR, en estudios sobre distribución de especies en ecosistemas marinos y de agua dulce de Colombia. Este programa se encuentra disponible en la Web de manera gratuita: <http://www.ipez.es/ModestR>. Para enseñar y probar el funcionamiento de ModestR se trabajó con los datos disponibles en el Global Biodiversity Information Facility (GBIF, 2012) de los órdenes Characiformes y Siluriformes, como ejemplo de especies de peces dulciacuícolas, y del orden Carcharhiniformes de especies marinas. ModestR incluye en su fase inicial, dos aplicaciones: DataManager y MapMaker. La aplicación DataManager está diseñada para realizar manejo integrado de información taxonómica y mapas de distribución de cualquier grupo de especies. La aplicación MapMaker permite generar mapas de distribución de especies de cuatro formas diferentes: 1) importando un archivo CSV con el nombre de las especies y las coordenadas geográficas, 2) importando los datos automáticamente del GBIF, 3) importando las coordenadas geográficas generadas de modelos de distribución y 4) realizando mapas expertos, lo cual consiste en seleccionar las áreas de distribución, de acuerdo a los tipos de hábitats en que ocurre la o las especies en estudio. La posibilidad de trabajar con hábitats es una de las contribuciones más importantes de ModestR y, en particular, la de que los hábitats lóticos pequeños (quebradas, arroyos, etc.), los lóticos grandes (ríos) y los lenticos (lagunas, lagos, embalses, ciénagas, etc.) están cartografiados con muy alta resolución. Además, también se diferencian los ecosistemas marino y terrestre. A pesar de que este estudio se enfocó en especies de ecosistemas acuáticos, ModestR permite también realizar el mismo tipo de ejercicios con especies terrestres.

Los microorganismos, esporas, ácaros y polen son componentes naturales del aire en ambientes internos y pueden ser transportados desde el exterior por partículas aerobiológicas que pueden establecerse en el polvo y causar el biodeterioro de diversos materiales, además de representar un riesgo para la salud de las personas. Con este trabajo, se evaluó la concentración microbiana en el ambiente de la Biblioteca Central Jorge Palacios Preciado, Universidad Pedagógica y Tecnológica de Colombia. Se empleó el método de sedimentación en placa para realizar el muestreo microbiológico del ambiente, utilizando agar Sabouraud para el aislamiento de hongos y agar nutritivo para bacterias. La densidad microbiana del ambiente se encontró dentro de los límites de sanidad aceptados para ambientes de lugares públicos, y la mayor diversidad identificada estuvo representada por 34 géneros de hongos filamentosos y un grupo de hongos de la clase Phycomycetes, siendo las esporas de los géneros Cladosporium, Paecilomyces y Penicillium, las más frecuentes en la biblioteca. Las levaduras fueron las menos representativas en el ambiente con dos géneros aislados Candida y Rhodotorula. En cuanto a las bacterias, se aislaron en total 16 géneros, de los cuales Bacillus y Neisseria, fueron los más comunes. Teniendo en cuenta los géneros microbianos aislados y las investigaciones más recientes, el ambiente de la Biblioteca Central podría representar un riesgo para la salud de las personas, principalmente a nivel respiratorio, sino se adoptan algunas medidas de limpieza y de adecuación de los sistemas de ventilación.

Published: January 2023

Este trabajo consistió en identificar y describir la anatomía externa e interna del cerebro de Paracheirodon axelrodi (Schultz, 1956, Characiformes: Characidae). Se emplearon 28 individuos los cuales fueron sacrificados de acuerdo a protocolos de ética para investigación con animales. Las cabezas fueron conservadas en formaldehído al 4%. Posteriormente se realizó la disección de estas para la descripción morfológica del cerebro y obtención de imágenes. Asimismo, se cuantificaron medidas de longitud y área de algunos lóbulos cerebrales (bulbos olfativos, hemisferios telencefálicos, lóbulos ópticos y cerebelo) y se realizó una ANOVA para comprobar si existían diferencias de tamaño en estas regiones. Para la topología del cerebro se siguió el protocolo para la obtención de cortes en parafina y se realizó tinción de Nissl. El cerebro de P. axelrodi está conformado por varios lóbulos conservando el patrón general descrito para otros teleósteos, sin embargo como características particulares se encontró que los bulbos olfativos son sésiles; el cerebelo presentó un tamaño moderado y no se evidenció la presencia de lóbulos faciales. En el análisis morfométrico tanto en longitud como en área se encontraron diferencias altamente significativas entre las estructuras evaluadas (p < 0,001), siendo los lóbulos ópticos la región de mayor tamaño, sugiriendo una dependencia mayor del sentido de la vista. En cuanto a la topología, el cerebro de P. axelrodi presenta características similares en la disposición de núcleos a las descritas en otros grupos de teleósteos.

Published: January 2023

Se implementó la metodología Hydrophobic Cluster Analysis (HCA) para evaluar la presencia y distribución de las lacasas (p-difenol:oxígeno-oxidorreductasas) en Bacteria. Por su alto nivel de resolución en entornos de baja identidad (< 30%), el análisis estructural mediante HCA fue capaz de validar secuencias huérfanas alojadas en las bases de datos Genbank y Swissprot. Se proponen consensos (LOGO) para los centros de cobre, ̇tiles para la identificación de nuevas lacasas. De la misma manera que en Coprinus cinereus, en la lacasa CotA de Bacillus subtilis se encontraron evidencias de un evento de duplicación intragénica [aminoácidos 1 a 178 (dominio A) y 303 a 503 (50 residuos del dominio B y todo el dominio C)]. La identidad entre los duplicados se calculó en 9%. Estos resultados permiten concluir que las lacasas de Bacteria y Eucarya tuvieron un ancestro común.

Seafloor Observations Eliminate a Landslide as the Source of the 1918 Puerto Rico Tsunami

ABSTRACT
The 11 October 1918 devastating tsunami in northwest Puerto Rico had been used as an example for earthquake-induced landslide tsunami hazard. Three pieces of evidence pointed to a landslide as the origin of the tsunami: the discovery of a large submarine landslide scar from bathymetry data collected by shipboard high-resolution multibeam sonar, reported breaks of submarine cable within the scar, and the fit of tsunami models to flooding observations. Newly processed seafloor imagery collected by remotely operated vehicle (ROV) show, however, pervasive Fe–Mn crust (patina) on the landslide walls and floor, indicating that the landslide scar is at least several hundred years old. C14 dates of sediment covering the landslide floor verify this interpretation. Although we have not searched the region systematically for an alternative tsunami source, we propose a possible source—a two-segment normal-fault rupture along the eastern wall of Mona rift. The proposed fault location matches the published normal faults with steep bathymetry and is close to the International Seismological Center–Global Earthquake Model catalog locations of the 1918 mainshock and aftershocks. The ROV observations further show fresh vertical slickensides and rock exposure along the proposed fault trace. Hydrodynamic models from an Mw 7.2 earthquake rupture along the eastern wall of the rift faithfully reproduce the reported tsunami amplitudes, polarities, and arrival times. Our analysis emphasizes the value of close-up observations and physical samples to augment remote sensing data in natural hazard studies.
“Aftershock Faults” and What They Could Mean for Seismic Hazard Assessment

Abstract
We study stress-loading mechanisms for the California faults used in rupture forecasts. Stress accumulation drives earthquakes, and that accumulation mechanism governs recurrence. Most moment release in California occurs because of relative motion between the Pacific plate and the Sierra Nevada block; we calculate relative motion directions at fault centers and compare with fault displacement directions. Dot products between these vectors reveal that some displacement directions are poorly aligned with plate motions. We displace a 3D finite-element model according to relative motions and resolve stress tensors onto defined fault surfaces, which reveal that poorly aligned faults receive no tectonic loading. Because these faults are known to be active, we search for other loading mechanisms. We find that nearly all faults with no tectonic loading show increase in stress caused by slip on the San Andreas fault, according to an elastic dislocation model. Globally, faults that receive a sudden stress change respond with triggered earthquakes that obey an Omori law rate decay with time. We therefore term this class of faults as “aftershock faults.” These faults release ∼4% of the moment release in California, have ∼0.1%–5% probability of M 6.7 earthquakes in 30 yr, and have a 0.001%–1% 30 yr M 7.7 probability range.
The seismic response of the Los Angeles basin, California
Authors: Wald David J. , Graves Robert W. 
Published: January 2023

AbstractUsing strong-motion data recorded in the Los Angeles region from the 1992 (Mw 7.3) Landers earthquake, we have tested the accuracy of existing three-dimensional (3D) velocity models on the simulation of long-period (≧2 sec) ground motions in the Los Angeles basin and surrounding San Fernando and San Gabriel Valleys. First, the overall pattern and degree of long-period excitation of the basins were identified in the observations. Within the Los Angeles basin, the recorded amplitudes are about three to four times larger than at sites outside the basins; amplitudes within the San Fernando and San Gabriel Valleys are nearly a factor of 3 greater than surrounding bedrock sites. Then, using a 3D finite-difference numerical modeling approach, we analyzed how variations in 3D earth structure affect simulated waveforms, amplitudes, and the fit to the observed patterns of amplification. Significant differences exist in the 3D velocity models of southern California that we tested (Magistrale et al., 1996; Graves, 1996a; Hauksson and Haase, 1997). Major differences in the models include the velocity of the assumed background models; the depth of the Los Angeles basin; and the depth, location, and geometry of smaller basins. The largest disparities in the response of the models are seen for the San Fernando Valley and the deepest portion of the Los Angeles basin. These arise in large part from variations in the structure of the basins, particularly the effective depth extent, which is mainly due to alternative assumptions about the nature of the basin sediment fill. The general ground-motion characteristics are matched by the 3D model simulations, validating the use of 3D modeling with geologically based velocity-structure models. However, significant shortcomings exist in the overall patterns of amplification and the duration of the long-period response. The successes and limitations of the models for reproducing the recorded ground motions as discussed provide the basis and direction for necessary improvements to earth structure models, whether geologically or tomographically derived. The differences in the response of the earth models tested also translate to variable success in the ability to successfully model the data and add uncertainty to estimates of the basin response given input “scenario” earthquake source models.
Use of fault striations and dislocation models to infer tectonic shear stress during the 1995 Hyogo-Ken Nanbu (Kobe) earthquake

Published: January 2023

AbstractDislocation models of the 1995 Hyogo-ken Nanbu (Kobe) earthquake derived by Yoshida et al. (1996) show substantial changes in direction of slip with time at specific points on the Nojima and Rokko fault systems, as do striations we observed on exposures of the Nojima fault surface on Awaji Island. Spudich (1992) showed that the initial stress, that is, the shear traction on the fault before the earthquake origin time, can be derived at points on the fault where the slip rake rotates with time if slip velocity and stress change are known at these points. From Yoshida's slip model, we calculated dynamic stress changes on the ruptured fault surfaces. To estimate errors, we compared the slip velocities and dynamic stress changes of several published models of the earthquake. The differences between these models had an exponential distribution, not gaussian. We developed a Bayesian method to estimate the probability density function (PDF) of initial stress from the striations and from Yoshida's slip model. Striations near Toshima and Hirabayashi give initial stresses of about 13 and 7 MPa, respectively. We obtained initial stresses of about 7 to 17 MPa at depths of 2 to 10 km on a subset of points on the Nojima and Rokko fault systems. Our initial stresses and coseismic stress changes agree well with postearthquake stresses measured by hydrofracturing in deep boreholes near Hirabayashi and Ogura on Awaji Island. Our results indicate that the Nojima fault slipped at very low shear stress, and fractional stress drop was complete near the surface and about 32% below depths of 2 km. Our results at depth depend on the accuracy of the rake rotations in Yoshida's model, which are probably correct on the Nojima fault but debatable on the Rokko fault. Our results imply that curved or cross-cutting fault striations can be formed in a single earthquake, contradicting a common assumption of structural geology.
Potential Mechanisms of Interior Lymphatic Vessel Primo Vessels in Tissue Repair

Published: January 2023

The Primo Vascular System was discovered by Bong Han Kim in the 1960s when searching for an anatomical correlate of the acupuncture meridians used in eastern medicine. The Primo Vascular System is a systemic network of thread-like Primo-vessels with intermittent enlargements known as Primo-nodes. Primo-vessels are difficult to view under a microscope due to their small diameters (20-50 µm) and translucent appearance. Primo-vessels have a porous outer membrane that encapsulates small channels named Primo sub-vessels filled with flowing fluid. Primo-vessels are classified into six sub-types based on their anatomical location. The physiological mechanisms of Primo-vessel function are not clear. There are multiple hypotheses based on Primo-vessel and Primo-node structure and cell content, however, supportive functional experimental data is lacking. This review focuses on the "interior" lymphatic vessel Primo-vessel (ILVPV) sub-type, the techniques that are used to visualize them, and experimental studies that attempt to unravel their physiological role after inflammatory stimulation. Speculative hypotheses are presented regarding the handling of signals by ILVPVs for intercellular communication between injured cells and cells stored within "interior" lymphatic vessel Primo-nodes (ILVPNs). One of the stored cell types that are of interest for tissue repair are very small embryonic-like cells. Very small embryonic-like cell activation may be induced by biophoton signals emitted by injured cells and transmitted to ILVPNs via Primo-vessel and/or ILVPV networks. An alternative or additional method for intercellular communication may involve the release of signaling proteins and/or extravesicular bodies carrying genetic messages (i.e., exosomes) by cells in injured tissues. As these signaling factors enter the lymphatic circulation, porous ILVPVs filter them out and transport them to ILVPNs where they initiate very small embryonic-like cell activation to start the tissue regenerative process. Primo Vascular System research will require more physiological functional studies to elucidate the role of ILVPVs and ILVPNs in tissue regeneration. To achieve this goal, future mechanistic studies will need novel biomarkers and animal models.
