Pseudo-Ductile 3d Printed Fiber Reinforced Polymer Composites, Shreya Vemuganti

Civil Engineering ETDs

The use of fiber-reinforced polymer (FRP) composite materials is continuously growing in civil infrastructure owing to its high strength, low weight, and manufacturing flexibility. However, FRP is characterized by sudden failure and lacks ductility. When used in construction, gradual failure of FRP components is desired to avoid catastrophic structural collapse. Due to its mechanical orthotropy, the behavior of FRP relies significantly on fiber orientation and stacking sequence. In this research proposal, investigations showed that novel multi-angled glass fiber reinforced polymer (GFRP) composites with varying fiber orientation angles, stacking sequence, and thickness of laminas can be designed and fabricated using 3D …

Outdoor Activity: Benefits And Risks To Recreational Runners During The Covid-19 Pandemic, Aswar Makruf, Doni Hikmat Ramdhan

Kesmas

Running has become one of the most popular recreational sports worldwide. It is an easily accessible form of exercise as there are minimal equipment andsport structure requirements. Aerodynamic simulation experiments showed a risk of droplet exposure between runners when two people run in a straight lineat a close distance (slipstream). Thus, running activities require a safe physical distance of 10 meters to avoid droplet exposure, which can be a source oftransmission of COVID-19 infection. However, running outdoors during the COVID-19 pandemic is still often done in pairs and even in groups without wearinga mask. Open window theory stated that changes …

Covid-19 And The City: A Healthy City Strategy For Pandemic Challenges, From Planning To Action, Hamzah Hasyim, Patricia Dale

Kesmas

COVID-19 is a respiratory disease caused by SARS-CoV-2, a new coronavirus discovered in 2019. WHO declared COVID-19 is a respiratory disease causedby SARS-CoV-2 as a pandemic that the detection level of cases changed daily, and it can track almost in real-time. This paper used a narrative literaturereview to address issues of urban quality and lack of exercise. The specific aim was to discuss the concept of a healthy city, indicate a new urban model, andadvocate for the increased use of bicycles, outdoor gym/outdoor exercise, walking to reducing pollution, and improving physical, psychological, and social fitness. A healthy city can improve …

Preventing And Controlling Covid-19: A Practical-Based Review In Offshore Workplace, Hendar Sunandar, Doni Hikmat Ramdhan

Kesmas

An offshore platform is a workplace with complex facilities and limited space due to the complex installed equipment and components. Therefore, the offshoreas enclosed area platform is more likely to have a high risk of COVID-19 outbreak. Furthermore, a company must strictly follow health protocols to preventworkers from being exposed to COVID-19 in the offshore workplace. However, workers are often forced to onboard without proper health protocols becauseof operational needs and production targets. This paper aimed to explore the essence of the steps in preventing and controlling COVID-19 in the offshoreworkplace and the challenges. The analysis found that the company …

Sinovac Vaccine Polemic Disinformation In Asymmetrical Warfare Perspective, Fera Belinda, Maria Puspitasari

International Review of Humanities Studies

The polemic of the China produced Sinovac Vaccine issue spreading among the public, is a form of disinformation used by political opposition to the government, to block and mess up the government’s effort to accelerate handling of Covid-19 transmission in Indonesia. The polemic results in 4 situations, namely; first, decreasing public trust in the government's commitment in eradicating the Covid-19 pandemic. Second, low level of support from the public of the Covid-19 handling programs. Third, delayed and slow economic recovery which brings down the public's economic ability due to increasing number of layoffs caused by decreases in companies’ turnover and …

Sentiment Analysis Of Digital Nomad In Indonesia: A Case Study In Bali, Dewi Puspita Rahayu, Ayu Kusumastuti, Wida Ayu Puspitosari

Masyarakat: Jurnal Sosiologi

The digital nomad is a new type of worker who works from a location other than a “traditional office,” with the freedom to choose where and when to work as long as they have good internet access. The presence of digital nomads has an impact on the dynamics or social changes in society. The public’s reaction to the appearance of this digital traveler was mixed. Some people believe that these new ways of working will harm the work system, but many are gradually adopt it. Bali has become one of the strategic locations and is widely used as a destination …

Comparison Of Expiring Cp-25 And 3-Year Old Cp-42 Plantings For Monarch Habitat Quality, Schuyler Hop, Laura L. Jackson Ph.D.

Summer Undergraduate Research Program (SURP) Symposium

Monarch butterflies have experienced a population decline of more than 80% in the past two decades, driven by the emergence of Roundup Ready beans and corn varieties. This development resulted in landowners spraying herbicides and killing all other plants in their field, including milkweeds, which is the genus of plants (Asclepias) that monarch caterpillars can only feed upon. Along with this development, an initiative to reintroduce native prairie ecosystems as part of the Conservation Reserve Program (CRP). In Iowa, over 80% of the land once was home to this prairie, now less than 0.1% of this rare ecosystem …

Probability Distributions For Elliptic Curves In The Cgl Hash Function, Dhruv Bhatia, Kara Fagerstrom, Max Watson

Mathematical Sciences Technical Reports (MSTR)

Hash functions map data of arbitrary length to data of predetermined length. Good hash functions are hard to predict, making them useful in cryptography. We are interested in the elliptic curve CGL hash function, which maps a bitstring to an elliptic curve by traversing an inputdetermined path through an isogeny graph. The nodes of an isogeny graph are elliptic curves, and the edges are special maps betwixt elliptic curves called isogenies. Knowing which hash values are most likely informs us of potential security weaknesses in the hash function. We use stochastic matrices to compute the expected probability distributions of the …

Retelling Mecca: Shifting Narratives Of Sacred Spaces In Volga-Ural Muslim Hajj Accounts, 1699–1945, Danielle Ross

History Faculty Publications

This article examines how Volga-Ural Muslims narrated their encounters with the sacred spaces visited during the hajj. It examines nine accounts hajj composed from the 1690s to the 1940s, to consider how changes in international politics, Russia’s domestic politics, and the culture of Islamic learning within the Volga-Ural Muslim community led to writers to revise narratives of why the sacred spaces of Mecca were sacred, how best to experience the power of these sacred spaces, and how these sacred spaces fit into the local culture of Volga-Ural Islam under Russian and Soviet rule.

Quantitative Analysis Of The Membrane Affinity Of Local Anesthetics Using A Model Cell Membrane., Wanjae Choi, Hyunil Ryu, Ahmed Fuwad, Seulmini Goh, Chaoge Zhou, Jiwook Shim, Masahiro Takagi, Soonjo Kwon, Sun Min Kim, Tae-Joon Jeon

Henry M. Rowan College of Engineering Departmental Research

Local anesthesia is a drug that penetrates the nerve cell membrane and binds to the voltage gate sodium channel, inhibiting the membrane potential and neurotransmission. It is mainly used in clinical uses to address the pain of surgical procedures in the local area. Local anesthetics (LAs), however, can be incorporated into the membrane, reducing the thermal stability of the membrane as well as altering membrane properties such as fluidity, permeability, and lipid packing order. The effects of LAs on the membrane are not yet fully understood, despite a number of previous studies. In particular, it is necessary to analyze which …
