Ultrafast Laser-Induced Damage And The Influence Of Spectral Effects, Jeremy R. Gulley

Faculty Articles

Numerous studies have investigated the prerequisite role of photoionization in ultrafast laser-induced damage (LID) of bulk dielectrics. This study examines the role of spectral width and instantaneous laser frequency in LID using a frequency dependent multiphoton ionization (MPI) model and numerical simulation of initially 800 nm laser pulses propagating through fused silica. Assuming a band gap of 9 eV, MPI by an 800 nm field is a six-photon process, but when the instantaneous wavelength is greater than 827 nm an additional photon is required for photoionization, reducing the probability of the event by many orders of magnitude. Simulation results suggest …

Pataya: Suatu Tinjauan Konstruksi Tempat Ngèbèr Komunitas Gay Di Surabaya, Kathleen Azali

Makara Human Behavior Studies in Asia

Tempat ngèbèr, or hanging-out places where gay men in Indonesia meet, can be found in various—though relatively hidden—public places across Indonesia. Tempat ngèbèr as one of the more prominent sites in the constellation of gay serves not only as a space to find sexual partners, but also to socialize, to be open in expressing oneself, and to gain acceptance from one’s peers. Surabaya has a number of famous, well-known tempat ngèbèr, with Pataya being one of the largest places. Yet changes within the last few years have diminished its popularity. Through participant observation and non-formal interviews, this research attempts to …

A Genetic, Transgenic, And Transcriptomic Analysis Of Larval Salivary Gland Physiology In Drosophila Melanogaster, Elana A. Paladino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cholesterol is the precursor to a unique class of lipophilic signaling molecules called steroid hormones that initiate the development of sexual characteristics, reactions to stress, and maintenance of metabolism, among many other functions. Although much progress has been made in understanding the function of these signaling hormones, we do not fully understand how a single steroid can cause many distinct, tissue-specific responses. Drosophila melanogaster is an effective model for understanding steroid hormone action because of its simplicity. The steroid molting hormone 20-hydroxyecdysone (hereafter, 20E) is the primary active steroid in Drosophila and mediates not only larval molts and the emergence …

Investigating The Impacts Of Conventional And Advanced Treatment Technologies On Energy Consumption At Satellite Water Reuse Plants, Jonathan Roy Bailey

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the ever increasing world population and the resulting increase in industrialization and agricultural practices, depletion of two of the world's most important natural resources, water and fossil fuels, is inevitable. Water reclamation and reuse is the key to protecting these natural resources. Water reclamation using smaller decentralized wastewater treatment plants, known as satellite water reuse plants (WRP), have become popular in the last decade. With stricter standards and regulations on effluent quality and requirements for a smaller land footprint (i.e. real estate area), additional treatment processes and advanced technologies are needed. This greatly increases the energy consumption of an …

School Leadership Readiness: Traditional Vs. Online Administrative Preparation, Jose Delfin

UNLV Theses, Dissertations, Professional Papers, and Capstones

According to the National Center of Educational Statistics (2006-2007) report, 92% of two and four-year Title IV degree-granting postsecondary institutions offered distance education courses due to students' demand for flexible scheduling. That same report cited that 82% of those institutions were seeking to increase student enrollment via distance education. There is little empirical research that pertain to the topic of degrees earned through online, or hybrid methods that have any bearing on job preparedness for past, present, and future educational leadership candidates.

Jitter Impact On Clock Distribution In Lhc Experiments, S. Baron, Themis Mastoridis, J. Troska, P. Baudrenghien

Physics

The LHC Bunch Clock is one of the most important accelerator signals delivered to the experiments. Being directly derived from the Radio Frequency driving the beams in the accelerator by a simple division of its frequency by a factor of 10, the Bunch Clock signal represents the frequency at which the bunches are crossing each other at each experiment. It is thus used to synchronize all the electronics systems in charge of event detection. Its frequency is around 40.079 MHz, but varies with beam parameters (energy, particle type, etc) by a few hundreds of Hz. The present paper discusses the …

Development And Evaluation Of Beat Management Practices (Bmps) For Highway Runoff Pollution Control, Daniel Edward Jones

Department of Environmental Engineering: Theses and Other Student Research

As non-point source pollution, storm water runoff is one of the main contributors to stream impairment in the United States. The United States Environmental Protection Agency (USEPA) requires Municipal Separate Storm Sewer Systems (MS4s) to obtain a permit under the National Pollution Discharge Elimination System (NPDES) to manage this pollution. Many municipalities and non-traditional MS4s such as the Nebraska Department of Roads are under federal regulations that require new developments or redevelopments of a certain size to capture (and treat) runoff from all new impervious surfaces (roofs, driveways, sidewalks, and so forth) onsite, instead of allowing it to run into …

Divided We Stand: Defying Hegemony In Theory And Practice, Anne Gregory, Gregor Halff

Research Collection Lee Kong Chian School Of Business

The last decade has seen the world becoming increasingly complex. One way of dealing with complexity, according to Schwab (2010a), is to look for certainties or solutions that impose order by simplifying. The authors contend that this is also happening in public relations practice and the academy. They criticise attempts to produce global models which lead to hegemony and argue for maintaining a diversity that reflects reality. They take the cases of the UK and Singapore as respective exemplars where hegemony has succeeded and where it needs to be resisted. They call for a professional and epistemological stand against hegemony.

Chemical Communication In The Honey Bee Scarab Pest Oplostomus Haroldi: Role Of (Z)-9-Pentacosene, Ayuka T. Fombong, Peter E.A. Teal, Richard T. Arbogast, Paul N. Ndegwa, Lucy W. Irungu, Baldwyn Torto

All Peer-Reviewed Publications

Oplostomus haroldi Witte belongs to a unique genus of afro-tropical scarabs that have associations with honey bee colonies, from which they derive vital nutrients. Although the attributes of the honey bee nest impose barriers to communication among nest invaders, this beetle still is able to detect conspecific mates for reproduction. Here, we show, through behavioral studies, that cuticular lipids serve as mate discrimination cues in this beetle. We observed five steps during mating: arrestment, alignment, mounting, and copulation, and a post-copulatory stage, lasting ~40-70 % of the total mating duration, that suggested mate guarding. Chemical analysis identified the same nine …
