Cultural Violence In Saki’S “The Toys Of Peace” And Ahmed Al-Malik’S “The Tank”, Maha Qahtan Sulaiman

Uruk Journal of Human Sciences

Violence cannot be separated from human culture, civilization, and ideology. Ironically, it is society that creates the borders of legal and illegal violence. Therefore, violence is culturally relevant. This paper examines the culture of violence in Saki’s “The Toys of Peace” and Ahmed Al-Malik’s “The Tank.” The two short stories are set in entirely different backgrounds and address violence in relation to children’s and adults’ lives, respectively. The study aims to examine violence in relation to culture and man’s primitive instincts. It also addresses controlling violence through education, promoting peace, and encouraging refined codes of conduct. The paper juxtaposes violence …

The Power Of Eponyms: Exploring Cultural And Social Factors In Their Adoption And Popularization, Sawsan A. Qasim

Uruk Journal of Human Sciences

The aim of this article is to investigate eponyms, which are not just linguistic phenomena but also cultural since they demonstrate one's influence on society and history. Words formed from a person's name, such as "volt" from Alessandro Volta and "sandwich" from John Montagu, 4th Earl of Sandwich, are examples of eponyms. Eponyms can be used to honor prominent persons, such as scientists, innovators, or well-known figures. They also demonstrate how society prioritizes specific accomplishments or attributes, as in the situations of “Fahrenheit” and “Celsius,” which are named after two pioneering scientists in the field of temperature measurement. Eponyms may …

Genome-Wide Search Algorithms For Identifying Dynamic Gene Co-Expression Via Bayesian Variable Selection, Wenda Zhang, Zichen Ma, Lianming Wang, Daping Fan, Yen Yi Ho

Faculty Publications

A wealth of gene expression data generated by high-throughput techniques provides exciting opportunities for studying gene-gene interactions systematically. Gene-gene interactions in a biological system are tightly regulated and are often highly dynamic. The interactions can change flexibly under various internal cellular signals or external stimuli. Previous studies have developed statistical methods to examine these dynamic changes in gene-gene interactions. However, due to the massive number of possible gene combinations that need to be considered in a typical genomic dataset, intensive computation is a common challenge for exploring gene-gene interactions. On the other hand, oftentimes only a small proportion of gene …

Modeling The Population Dynamics And Movement Of Zebra Mussels, Alexanderia Lacy, Yu Jin, David Strayer, Suzanne Lenhart

Department of Mathematics: Faculty Publications

Zebra mussels have caused significant damage in many lakes and rivers. By using a hybrid population model with discrete-time equations and ordinary differential equations, we represent the zebra mussel’s life cycle, growth, and population movement. The dynamics of the larvae (unsettled and settled larvae) are represented during the summer months in a system of two ordinary differential equations, while the juvenile, small adult, and large adult stages are represented by a discrete model with yearly time steps. The goal is to investigate the effects of zebra mussel movement between three different spatial locations and possible control measures. Zebra mussel data …

Two-Pore Channel-2 And Inositol Trisphosphate Receptors Coordinate Ca2+ Signals Between Lysosomes And The Endoplasmic Reticulum, Yu Yuan, Vikas Arige, Ryo Saito, Qianru Mu, Gabriela C. Brailoiu, Gustavo J.S. Pereira, Stephen R. Bolsover, Marco Keller, Franz Bracher, Christian Grimm, Eugen Brailoiu, Jonathan S. Marchant, David I. Yule, Sandip Patel

College of Pharmacy Faculty Papers

Lysosomes and the endoplasmic reticulum (ER) are Ca2+ stores mobilized by the second messengers NAADP and IP3, respectively. Here, we establish Ca2+ signals between the two sources as fundamental building blocks that couple local release to global changes in Ca2+. Cell-wide Ca2+ signals evoked by activation of endogenous NAADP-sensitive channels on lysosomes comprise both local and global components and exhibit a major dependence on ER Ca2+ despite their lysosomal origin. Knockout of ER IP3 receptor channels delays these signals, whereas expression of lysosomal TPC2 channels accelerates them. High-resolution Ca2+ imaging reveals elementary events upon TPC2 opening and signals coupled to …

Application Of Improved Path Tracking Algorithm In Robot Slam, Qian Li, Ye Tao, Hui Li

Journal of System Simulation

Abstract: Mapping is an important part of automated logistics. At present, SLAM is widely used. However, in large-scale scenes, errors are accumulated because robots often repeatedly measure and scan the region edge, which makes it impossible to quickly build a high-precision and complete map. An autonomous mapping method based on auxiliary path tracking is proposed, in which the given initial sketch is grid denoised and the auxiliary path is fitted and improved by multi segment cubic polynomial. The improved pure pursuit algorithm is used to guide the robot to build the map and improve the total distance and time of …

Modeling Of Amine-Based Co2 Capture Process, Zafar Safarovich Turakulov

Chemical Technology, Control and Management

A significant factor influencing climate change is the release of carbon dioxide (CO₂) into the atmosphere as a consequence of human activities such as the combustion of fossil fuels. Climate change can be slowed down by taking action to mitigate industrial-scale CO₂ emissions. Currently, the most advanced technology for capturing CO₂ from industrial flue gases is the post-combustion CO₂ capture based on amine absorption. However, due to the high energy penalties of existing CO₂ capture technologies and insufficient carbon markets, it is necessary to develop methods that compete with these technologies or minimize their …
