The Memories of the Dead: Trauma and Historical Memory in "[REC]"
… in these texts. Not surprisingly, it is precisely this element that, when analyzed, shifts the understanding we have of such narratives. An example of this phenomenon is the 2007 Spanish zombie film [REC] which, when reading through the lens of past historical traumas, is infused with a …

Theorizing and assessing racial-ethnic-cultural (rec) belonging among People of Color
… framework and measure of racial-ethnic-cultural (REC) belonging for Black, Indigenous, and other People of Color (BIPOC) across three phases of research represented by two interrelated studies. Phase 1 includes Study 1 of the research, which offers a phenomenologically grounded framework of REC …

Biophysical and Biochemical Characterization of a REC Domain: Unfolded to Folded Transition of EL_LovR
… these to control phosphorylation of the receiver domain of the response regulator, which convert this signal into a physiological response. Knowledge of how phosphorylation shifts receiver domains between their inactive and active states is limited, chiefly assembled from several …

Small lesion detection with resolution enhancement compression: a method of coded excitation/pulse compression
… method, resolution enhancement compression (REC), increases the axial resolution and the echo signal-to-noise ratio (eSNR) for an ultrasonic imaging system. The REC technique was examined for its ability to improve lesion detectability. In addition to lesion detectability, the REC technique …

Studies of Aurora and Polo Kinases During Cell Division in C. elegans
… segregation during cell division requires the precisely regulated release of chromosome cohesion. In mitosis, sister chromatids are linked by chromosome cohesion until the proteolysis of the cohesion Scc1 by separase triggers the separation of sister chromatids at anaphase. Chromosome dynamics …

Deep structure ultrasound imaging using fundamental and third harmonic coded excitation techniques
… chirps with resolution enhancement compression (REC) and frequency compounding, increases the axial resolution, lateral resolution, penetration depth and the contrast-to-noise ratio (CNR) for an ultrasonic imaging system. The thickness mode of piezoelectric transducers produces a signal that is …

Improving ultrasonic imaging using novel coded excitation techniques
… resolution depends on the source bandwidth. Recently, a novel coded excitation and pulse compression technique, known as Resolution Enhancement Compression (REC), was developed. REC enhances the -6 dB bandwidth of an ultrasonic imaging system. In this dissertation, the limitations of the REC …

How to Mend a Broken Mitochondrial Genome: Mitochondrial Recombination And Its Applications
… breaks can be accurately repaired by homologous recombination but spontaneous mtDNA recombination is only detected rarely in animals. A system to induce and select for mtDNA recombination was recently developed in the fruit fly, Drosophila melanogaster. In this thesis, I used this system to …

Tissue engineering of a tracheal substitute
… of human respiratory epithelial cells (REC) cultured on two biomaterial scaffolds. The first scaffold, based on a hyaluronic acid derivative, was observed to be non-adhesive for REC. This lack of adhesion was found to be unrelated to the presence of the hyaluronic acid binding domain on …

W-reactivation (Inducible "SOS" DNA Repair) of double stranded DNA bacteriophage ? and single stranded DNA bacteriophage fd on isogenic rec and uvrB mutants of Escherichia coli K-12
The recA mutant has been shown to be completely recombination deficient and highly UV-sensitive. Also, this mutant is remarkably deficient in inducible "SOS" DNA repair and, consequently it is not UV-mutable and it cannot perform W-reactivation, an inducible non-excision repair dependent …

Observations of a particle capture on a cylindrical collector : implications for particle accumulation and removal in aquatic systems
… filtration. The collector Reynolds number (Rec), based on the collector diameter, typically ranges from 1-1000 in aquatic environments. No analytical solutions exist to describe capture efficiency in this range. Laboratory experiments are used to measure capture efficiency of a single …

An investigation of psychophysiological stress in competitive golf
… groups of players, professional trainee (PRO), recreational (REC) and elite amateur (AMA). The PRO and REC golfers, comprising a high and moderate ability group respectively, were additionally studied during a practice golf round. Competition stress was determined by comparing …

Elucidating Collagen Degradation Synergy between Col G and Col H from Hathewaya (Clostridium) histolytica and Identifying novel structural features in HPT and REC domains from VarS histidine kinase in V. alginolyticus
… (dHp) domain and a response regulator. For REC domain, itasser homology model and limited proteolysis revealed a two-domain structure connected by a flexible linker. Based on B-factor of linker truncation may be necessary for crystallization of the domain. In this study we initially sought …

US Green Hydrogen Production: Strategic Approaches to Enhancing Economic Viability and Market Development
… on the pivotal role of renewable energy credit (REC) matching criteria and strategic operational adjustments in enhancing its economic feasibility. Through a detailed examination of the effects of hourly and annual REC matching, this study illuminates the complex interplay between public policy, …

Climate changing in microwave telecommunication links (sleet)
Rec. ITU-R P.530-12 provides an internationally recognised prediction model for the fading due to wet snow (sleet) on horizontal, terrestrial microwave links. An important parameter in this model is the altitude difference between the link and the melting layer. This is the layer near the …

Distortions of the genetic map of chromosome I in Caenorhabditis elegans
… of sex, mutation, and rearrangement on meiotic recombination in Caenorhabditis elegans were investigated. The short life cycle and existence of meiotic mutants make this organism an ideal system in which to study meiosis. To determine the effect of sex on meiotic recombination, crossing over was …

Effect of Flow-Acoustic Resonant Interactions on Aerodynamic Response of Transitional Airfoils
… in the realistic transitional flow regimes with Rec=140,000 and M=0.0465 as well as the low Reynolds number flow regime with Rec=10,000 and M=0.2. The symmetric NACA-0012 and the cambered SD7003 airfoils are investigated at various angles of attack that have been found previously to include both …
