Analysis of RNA stability in forensic specimens
Ribonucleic acid (RNA) analysis presents a unique, novel opportunity to answer a wide range of questions in forensic science. The dynamicity of the transcriptome has led to it being suggested as a novel source of diagnostic information in forensic pathology. However, RNA is exceptionally labile. …

KSHV Susceptibility and Transmission Within Tonsillar Specimens
… we generated a library of 40 tonsillar specimens. Our results indicate that the immunological composition of tonsillar lymphocytes varies across our donor samples, and KSHV possess a diverse B lymphocyte tropism. Furthermore, the highly specific targeting of plasma cells is not due to …

Two Methods of Collecting Clean-voided Urine Specimens
… as the method of study. Two clean-voided urine specimens were obtained from twenty-six nursing students in a selected school of nursing. One clean-voided urine specimen was obtained from each subject where the genitalia had not been cleansed and compared with a second clean-voided urine specimen …

Correlation of Shear Strength Between Longitudial and Transverse Specimens
<p>In this thesis, new methods for shear strength are proposed and backed up through extensive experimentation, ABAQUS models and data analysis of Titanium welds of three different alloys. The results are compared with those obtained by using the procedure outlined by AWS B4 for calculating Shear …

Characterization of bending fatigue mini-specimens for nuclear materials
… operating life. Studying fatigue of irradiated specimens is challenging due to space limitation in research reactors (e.g. ATR). The mini-specimen bending fatigue (Krouse-type) of nuclear materials was used to study fatigue properties and compare the obtained results with that of reference data …
