Tools For Prescreening The Most Active Sites On Ir And Rh Clusters Toward C−H Bond Cleavage Of Ethane: Nbo Charges And Wiberg Bond Indexes, Yingbin Ge, Anna Le, Gregory J. Marquino, Phuc Q. Nguyen, Kollin Trujillo, Morgan Schimelfenig, Ashley Noble

All Faculty Scholarship for the College of the Sciences

B3LYP calculations were carried out to study the insertion of iridium (Ir) and rhodium (Rh) clusters into a C−H bond of ethane, which is often the ratelimiting step of the catalytic cycle of oxidative dehydrogenation of ethane. Our previous research on Ir catalysis correlates the diffusivity of the lowest unoccupied molecular orbital of the Ir clusters and the relative activities of the various catalytic sites. The drawback of this research is that the molecular orbital visualization is qualitative rather than quantitative. Therefore, in this study on C−H bond activation by the Ir and Rh clusters, we conducted analyses of natural …

Detecting Digitally Forged Faces In Online Videos, Neilesh Sambhu Oct 2019

Detecting Digitally Forged Faces In Online Videos, Neilesh Sambhu

USF Tampa Graduate Theses and Dissertations

We use Rossler’s FaceForensics dataset of 1004 online videos and their corresponding forged counterparts [1] to investigate the ability to distinguish digitally forged facial images from original images automatically with deep learning. The proposed convolutional neural network is much smaller than the current state-of-the-art solutions. Nevertheless, the network maintains a high level of accuracy (99.6%), all while using the entire FaceForensics dataset and not including any temporal information. We implement majority voting and show the impact on accuracy (99.67%), where only 1 video of 300 is misclassified. We examine why the model misclassified this one video. In terms of tuning …

Soil nitrogen mineralisation (Nmin), the conversion of organic into inorganic N, is important for productivity and nutrient cycling. The balance between mineralisation and immobilisation (net Nmin) varies with soil properties and climate. However, because most global-scale assessments of net Nmin are laboratory-based, its regulation under field-conditions and implications for real-world soil functioning remain uncertain. Here, we explore the drivers of realised (field) and potential (laboratory) soil net Nmin across 30 grasslands worldwide. We find that realised Nmin is largely explained by temperature of the wettest quarter, microbial biomass, clay content and bulk density. …

Letters On The Aesthetic Deformation Of Man, Katya Mandoki Oct 2019

Letters On The Aesthetic Deformation Of Man, Katya Mandoki

Contemporary Aesthetics (Journal Archive)

Friedrich Schiller wrote Letters on the Aesthetic Education of Man hoping to elevate human potential through the arts for the development of free citizens of the Republic, and also in reaction to the decline of the French Revolution into a Reign of Terror. Nowadays, with the prominent role social networks have acquired in human relations, aesthetics is an invaluable tool for capturing attention in marketing and political propaganda, no less than in recruitment and indoctrination by terrorist organizations. Adopting a pragmatics approach, we will examine Schiller’s relevance today regarding uses and abuses of aesthetics related to terrorism, focusing on the …

The Lives Of Things On Pulau Ujir; Aru’S Engagement With Commercial Expansion, Joss R. Whittaker

Wacana, Journal of the Humanities of Indonesia

In places with limited access to manufactured goods, people must develop creative strategies to make the most of available materials, both those produced by humans and those taken from the natural world. Although Pulau Ujir, in the Aru Islands, has a long history of engagement with global trade networks, until recently the community’s access to manufactured goods was limited and infrequent. As a result, in the past objects there tended to take on new lives, and still do today: they are modified, re-purposed, and recycled in ingenious ways. This article explores the relationship between people and things in Ujir from …

From Cymatics To Sound Therapy: Their Role In Spirituality And Consciousness Research, Victor Christianto, Kasan Susilo, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Sound is one of the types of waves that can be felt by the sense of hearing (ears). In physics, the definition of sound is something that is produced from objects that vibrate. Objects that produce sound are called sound sources. The sound source that vibrates will vibrate the molecules into the air around it. Sound is mechanical compression or longitudinal waves that propagate through the medium. This medium or intermediate agent can be liquid, solid, gas. So, sound waves can propagate for example in water, coal, or air. Most sounds are a combination of various vibratory signals composed of …

Dialogue Between Islam And Environtmental Ethics Through The Seyyed Hossein Nasr Thought, Aulia Rahman Nugraha, Naupal Asnawi

International Review of Humanities Studies

Islam is often regarded as a religion that teaches anthropocentrism through the concept of the caliph in which humans occupy a central position on earth. However, the concept of the caliph itself is a complex concept where the special status of humans always implies a moral obligation. Through alternative explanatory methods and critical reflection, the authors try to clarify the concept of the caliph and show the teachings of Islam that are environmentally friendly through the thought of Seyyed Hossein Nasr. Philosophy and environmental ethics of Nasr have two major projects, namely the resacralization of nature and the clarification of …
