Three-dimensional dynamic analyses of two Colombian high-rise buildings
Authors: Hart Gary C. 
Published: July 2021

Abstract
The actual earthquake damage in two high-rise buildings in Bogota, Colombia, is compared with predicted response of four three-dimensional analytic building models. Three building models of the 24-story steel frame Bank of Bogota and one of the 29-story concrete frame Bavaria Office Building are considered. Periods and mode shapes are calculated for each building model. Maximum interstory displacements, absolute roof accelerations, story shears, and torques are calculated in each building model for three well-recorded earthquakes, one being a July 1967 earthquake in Colombia, as recorded at a nearby Bogota seismograph station. In all earthquakes, both components of ground motion were applied simultaneously.
Strain adjustments associated with earthquakes in southern California
Authors: Smith Stewart W. , Van de Lindt William 
Published: July 2021

Abstract
A technique for the calculation of strain changes in a two-dimensional elastic body with arbitrary internal dislocations is presented. This technique is applied to the southern California region by assigning a specific fault and fault slip function for each major earthquake that has occurred since 1812. Although the model used has serious shortcomings when applied to the real Earth, certain important features concerning strain energy changes associated with earthquakes are brought out. The occurrence of earthquakes over the past 150 years has resulted in net increases in stored strain energy in a number of regions including the northern end of the Gulf of California, the Cajon Pass area, and the northern part of the Carizzo Plain. Large regions of strain energy decrease can also be seen, the most important of which is in the vicinity of Fort Tejon.
On Rayleigh waves in a wedge with free boundaries
Authors: Gutdeutsch Rudolf 
Published: July 2021

Abstract
Seismic modeling experiments have shown that a Rayleigh wave traveling toward the corner of a small angle wedge with free boundaries decomposes into two waves whose orbital motions are symmetric and antisymmetric with respect to the bisector of the wedge. Their local phase velocities are respectively equal to the phase velocities of the symmetric and antisymmetric Rayleigh mode in a plate with parallel boundaries where the thickness of the plate is equal to the local thickness cf the wedge. This experimental result has been used to construct an approximation theory to describe the propagation of Rayleigh waves in a wedge.
In this paper synthetic seismograms and particle motions computed with this theory are compared with seismograms produced by laboratory models.
Benndorf's formula for the dynamic magnification of an electromagnetic seismograph
Authors: Bollinger G. A. 
Published: July 2021

Abstract
The indicator equation for a seismogram from an electromagnetic seismograph is integrated under the assumption that the trace has the form of a suddenly beginning sinusoid. An expression for the velocity sensitivity is derived from the integrated result and applied to the particular case of a seismometer-galvanometer combination with natural frequencies of 2 Hertz-200 Hertz respectively. For that seismograph the dynamic velocity sensitivity at transducer—earth resonance is one-fifth of the steady-state harmonic sensitivity at resonance.
Aftershocks of the Dasht-e Bayāz, Iran, earthquake of August, 1968
Authors: Crampin Stuart 
Published: July 2021

abstract
Aftershocks of the Dasht-e Bayāz earthquake were recorded in the epicentral area with high-gain, high-frequency equipment. This study shows the general characteristics of the aftershock series. The foci are clustered near the ends of the 80 km surface faulting, at 25 km depth. In this earthquake sequence, the secondary series are not distinct in space or mechanism from the primary series, and microevents have the same strain release characteristics as the larger aftershocks.
Shear wave velocities in the lower mantle
Authors: Fairborn J. W. 
Published: July 2021

abstract
The Large Aperture Seismic Array in eastern Montana was used to measure the travel times and dT/dΔ of earthquake-generated shear waves for the purpose of determining lower-mantle shear velocities. The data were limited to epicentral distances between 27 and 95 degrees. To convert uncertainties in the dT/dΔ measurements to uncertainties in the computed velocities, the data were inverted by a Monte Carlo procedure. The computer randomly generated velocity models, and those which satisfied prescribed travel time and dT/dΔ-versus-Δ limits were considered as possible models for the real earth. The dT/dΔ curve possessed anomalously steep slopes between 27-30 and 65-75 degrees, and the corresponding velocity models had increased gradients between the approximate depths of 700-800 and 1550-2100 kilometers. The slope of the dT/dΔ curve also decreased at about 88 degrees which may indicate a decrease in velocity gradient several hundred kilometers above the core-mantle boundary. For epicentral distances greater than 27 degrees the observed travel times to LASA were greater than the expected J-B times. Although vague, a systematic increase in the observed residuals appeared to exist between 40 and 60 degrees which agreed with the J-B residuals of the computed models.
Asymptotic theory of body waves in a radially heterogeneous Earth
Authors: Singh Sarva Jit , Ben-Menahem Ari 
Published: July 2021

abstract
Various aspects of elastic wave propagation in a spherically symmetric, non-gravitating, isotropic, inhomogeneous medium are considered. It is shown through a simple example that the high frequency decoupling conditions of the vector wave equation may be approximately satisfied by real Earth models. An asymptotic theory is developed for the decoupled potential equations. This theory is applied to the case of a shear dislocation and to that of a center of compression in a radially heterogeneous medium. Explicit expressions are obtained for the ray-theoretical displacements.
Microearthquake activity in Eastern Nevada and death valley California before and after the nuclear explosion Benham
Authors: Molnar Peter , Jacob Klaus , Sykes Lynn R. 
Published: July 2021

abstractSix portable, high-gain, high-frequency seismographs were operated in Nevada and California for several weeks before and after the underground nuclear explosion Benham to assess the possibility that earthquakes at distances of tens of kilometers or more may be triggered by large underground explosions. A pronounced increase in earthquake activity in the vicinity of the shot point was observed immediately after the detonation and continued for more than a month after the explosion. No significant change in activity within 25 km of any of our instruments northeast of the Nevada Test Site was observed, and the activity in Death Valley recorded after the explosion did not indicate an important increase. These data imply that this particular explosion did not significantly affect the seismicity of the region studied. Throughout the period of observation the seismic activity northeast of the Nevada Test Site was low; an average of about one event per day was detected within about 25 km of each station. This suggests that the current tectonic activity of this part of Nevada is lower than that of western Nevada and of most other tectonically active regions where microearthquake studies have been made.
Aftershocks of the Benham nuclear explosion
Authors: Hamilton R. M. , Healy J. H. 
Published: July 2021

abstract
The Benham nuclear explosion, a 1.1 megaton test 1.4 km beneath Pahute Mesa at the Nevada Test Site, initiated a sequence of earthquakes lasting several months. The epicenters of these shocks were located within 13 km of ground zero in several linear zones that parallel the regional fault trends. Focal depths range from near surface to 6 km. The earthquakes are not located in the zone of the major ground breakage. The earthquake distribution and fault plane solutions together indicate that both right-lateral strike-slip fault movement and dip-slip fault movement occurred. The explosion apparently caused the release of natural tectonic strain.
Response of higherise buildings to ground motion from underground nuclear detonations
Authors: Blume John A. 
Published: July 2021

abstractTypical data obtained thus far in the AEC nuclear test program on the response of highrise Las Vegas buildings to ground motion from distant nuclear events including Boxcar and Benham are presented, together with measured building response to distant earthquakes and to wind gusts. Major variations in response spectra are shown over the city for a specific event, from period band to period band at the same location for different events, and statistical parameters are shown for the randomness of spectral response. The peak response of tall buildings is shown for the top levels in translation and in orbital motion, and in the vertical plane with simultaneous multi-level measurements. The variation of peak modal response is shown with elapsed time, modal combinations are noted, and an example of time-history computed response is compared to measured response. It is shown that highrise Las Vegas buildings respond to ground motion with considerable amplification, that the fundamental modes tend to dominate the peak responses although there are exceptions, that there can be significant modification of loading conditions because of simultaneous motion in the two horizontal axes even though a building is symmetric, and that some building periods vary with amplitude and history of non-damaging prior response while others do not. In general there are indications that code earthquake design criteria are by no means conservative.

Published: July 2021

Introduction: Coronavirus Disease (COVID‐19) has become the most important global health issue, and chest computed tomography (CT) scan can help determine the severity of the infection.
Objectives: This study aimed to provide an emergency scoring tool for predicting 30-day adverse outcomes in non-critical new-onset COVID-19 patients.
Methods: This derivation study was conducted on new-onset COVID-19 patients presenting to the emergency department of an urban teaching hospital in Tehran, Iran, between 20 February and 20 March 2020. The total lobe severity score (TSS), age, history of comorbidities, and 30-day adverse outcomes (death, ICU admission or intubation) were taken into account to produce three prediction models.
Results: Overall, 137 patients were included in the study. Their mean age was 59.9±16.8 years and 62% were male. The ground glass nodule, patch B/punctate ground-glass opacity, fibrous stripes, and air bronchogram sign with perihilar distribution, bilateral and ≥ 2 affected lobes were the most common findings. The mean TSS (model 1) was significantly higher in patients with an adverse outcome (9.4±3.2) compared to the discharged patients (7.2±3.3) (p<0.001, AUC: 0.703, sensitivity: 64.4% and specificity: 74.1%). The optimal cut-off point of model 2 (TSS and age) had the following parameters: AUC: 0.721, sensitivity: 71.2% and specificity: 67.2%. The optimal cut-off point of model 3 (TSS, age, comorbidities) had: AUC: 0.755, sensitivity: 79.7% and specificity: 65.5%. The discrimination achieved with model 3 based on Bonferroni’s test was significantly better than that achieved with TSS (p<0.001).
Conclusion: TSS combined with age and history of at least one comorbidity had a better predictive value for adverse outcomes with a cut-off point above 8.
Comparison of Video Laryngoscopy and Direct Laryngoscopy in the Success of Intubation Performed by Novice Personnel in Patients with Cervical Immobilization: A Manikin Study
Authors: Can Özge , Yalcinli Sercan , Altunci Yusuf Ali 
Published: July 2021

Introduction: Pre-hospital intubation is a challenging but essential intervention. During intubation, it is difficult to identify vocal cords when using a cervical collar and trauma board. Therefore, the success rate of intubation by paramedics decreases in trauma patients. Video laryngoscopy increases intubation success rate and has been recommended for difficult airways in studies.
Objective: In this study, we compared the intubation success rates when using a video laryngoscope and a direct laryngoscope in a manikin with simulated cervical immobilization.
Methods: In this cross-sectional study, the manikin’s neck collar and spine board created a complicated airway model with cervical immobilization. Inexperienced paramedic students tried intubation with both methods, and their trial periods were recorded. Students answered a question evaluating the convenience of the procedure for both methods after the trial.
Results: In this study, 83 volunteers, who were first-year and second-year paramedics, participated; 32 (38.6%) of the volunteers were first-year students, while 51 (61.4%) were second-year students. All volunteers had previous intubation experience with direct laryngoscopy, but not with video laryngoscopy. There was a statistically significant difference in the first-attempt success rates of the procedure between the groups in favor of video laryngoscope (p=0.022). Note that there was no significant difference between the groups in terms of first attempt durations (p=0.337).
Conclusion: Video laryngoscopy in airway management can increase the success rate of first-attempt intubation by inexperienced pre-hospital healthcare personnel.
Effects of nursing comfort care integrating with the daily Islamic rituals on comfort among mechanically ventilated Muslim patients: A randomized clinical trial
Authors: Rustam Junaidy Suparman , Kongsuwan Waraporn , Kitrungrote Luppana 
Published: July 2021

Background & Aim: Most mechanically ventilated patients reported decreasing comfort during their treatments, especially in Muslim patients. Nursing comfort care needs to be addressed by integrating daily Islamic rituals to fulfill the spiritual need and promote holistic comfort of Muslim patients with mechanical ventilation. This study aimed to investigate the effect of nursing comfort care integrating with the daily Islamic rituals on comfort among mechanically ventilated Muslim patients.
Methods & Materials: A pretest-postest with control group design was used. Fifty-six participants recruited from intensive care units of three public hospitals in Indonesia were randomly assigned into either the intervention group (n=28) or control group (n=28) by matching technique based on gender, age, and duration using a ventilator. Those in the intervention group received nursing comfort care developed based on Kolcaba’s Theory of Comfort integrating with the daily Islamic rituals, while those in the control group received usual care. Comfort was measured on the first day before receiving the intervention and on the second day after the intervention was completed by using Comfort Questionnaire for Mechanically Ventilated Patients (CQMVP).
Results: Data analysis using an independent t-test found no significant difference between the intervention and control groups at baseline (t = .134, p .894). The mean of comfort score of patients in the intervention group after receiving the intervention was significantly higher than those in the control group (t=6.70, p< .05).
Conclusion: Nursing comfort care integrated with daily Islamic rituals increased comfort in Muslim patients while receiving mechanical ventilation. Thus, this nursing comfort care program can be recommended to use in practice.

This research is aimed to figuring out the fanaticism from the members of an action figure community in Purwokerto called “Figure Purwokerto”. “Figure Purwokerto” community is an action figure community located in Purwokerto, Central Java, Indonesia. The total of the member is about 241 people from different age and culture. The researchers use focus group discussion and interview as the method to gain the information that the researcher needed for research purposes. The researchers applies some theories in order to obtain further analysis related to the issue. Fanaticism theory is used to figure out the fanaticism of “Figure Purwokerto” community’s members. Another theory, the Cultural Studies: Cultural Consumption Research, is added to make a deeper analysis about the consumption of culture from the members of the community. The scope of this research is cultural studies under the umbrella of English Studies which relates to American culture and supremacy with action figure as the media. Furthermore, the disscussion of this study is divided into two main parts which correspondent with the fanaticism happened in Figure Purwokerto community. The first part explains the portrayal of the fanaticism from the members of the community. The characteristics of a person can be said as a fanatics are included in this part. The second part explains the cultural relation between the members and the action figure as a culture. The result of this research concludes that the members are fanatic based on several aspects and characteristics of a fanatic. This research was also conducted to make another prespective of fanaticism which is seen as a bad term due to it’s relation to religion fanaticism.
