Optical Pumping of Rubidium Spin in a Solid Argon Matrix
Using the matrix isolation technique we have trapped rubidium atoms inside a cryogenic solid argon crystal of thickness 200 µm. This weakly-interacting solid offers the experimental simplicity and high densities of solid-state systems, while allowing the implanted atoms to retain many of the …

Substrate noise analysis and techniques for mitigation in mixed-signal RF systems
… frequencies as the effectiveness of standard isolation technique diminishes considerably. Historically, substrate noise was not a problem because each system was fabricated in its own package shielding it from such interactions. The work in this thesis spans all areas of substrate noise: …

Effects of magnesium deficiency on urinary glycoproteins in the rat
… were to be isolated in 0.58 M Na.Cl, the isolation technique for Tamm-Horsfall glycoprotein. Quantitative excretion was measured as ɣ hexose/rat/day. Qualitative analyses were reported as percent of dry weight of material isolated. A glycoprotein-containing material precipitated …

Isolation of Mesenchymal Stem Cells Derived from Adult Bone Marrow and Umbilical Cord Blood and Their Potential to Differentiate into Osteoblasts
… research is a feasibility study on a new isolation technique developed by our lab. The major focus of the research will be the isolation and characterization of mesenchymal stem cells from both adult bone marrow and umbilical cord blood using a novel isolation method based on …

Studies on Methylaluminoxane Catalyst Activators
… combining infrared spectroscopy with the matrix isolation technique. Low temperature NMR experiments successfully led to the identification of the AlMe3·H2O adduct as the first intermediate, followed by formation of Me2AlOH, when THF was employed as a solvent. Another approach focused on the …

Disconnection Techniquewith a Bronchial Blockerfor Improving Lung Deflation
… spontaneous collapse, and BB with disconnection technique. METHODS: Fifty-two patients undergoing elective pneumothorax surgery were included in this study. The patients were randomly assigned to one of three groups: DLT with spontaneous collapse group (Group 1), BB with spontaneous collapse …

The role of actinomycetes in the biodeterioration of wood
… soft rot cavities in this timber.<br/><br/>An isolation technique using comminution, homogenisation, and a high temperature pretreatment was developed to quantify actinomycete presence in wood and it was found that 10<sup>8</sup> actinomycete propagules per gram of wood were consistently …

Generalised Markovian analysis of timed transition systems
… known as the steady-state equations. Existing techniques of state space generation are surveyed and a new space-saving probabilistic dynamic state management technique is proposed and analysed in terms of its reliability and space complexity. State space reduction techniques involving …

NOVEL MECHANISMS FOR PROTEIN SYNTHESIS REGULATION DURING STRESS
… islets, we have developed a novel experimental technique by combining the islet isolation technique and deuterium water labeling method. The Akita mouse, which bears a point mutation on INS2 gene, was chosen for this study because the onset of diabetes does not involve obesity, insulin …

Lab on a chip rare cell isolation platform with dielectrophoretic smart sample focusing, automated whole cell tracking analysis script, and a bioinspired on-chip electroactive polymer micropump
… (cDEP) is a recently developed cell sorting and isolation technique that uses the DEP force by capacitavely coupling the electrodes across the channel. The cDEP platform sorts cells based on intrinsic biophysical properties, is inexpensive, maintains a sterile environment by using disposable …

Brillouin scattering induced transparency: Coherent optomechanical interaction leading to slow light and non-reciprocal light transmission
… difference in forward and backward transmission (isolation contrast) exceeding 40 dB over a wide range of laser wavelengths. In integrated photonic circuits, however, Faraday isolators are difficult to implement due to the lack of an established fabrication process for permanent magnets on-chip, …

Identification of centrosomal proteomes using COMPACT, a novel tool for purification of centrosomes
… I established a novel method for centrosome isolation that was developed in our laboratory. This approach, known as COMPACT (Centrosome Purification by Affinity Capture), involves a single-step affinity purification of centrosomes by a short peptide corresponding to a 33 amino acid C-terminal …

Development of a multi-stage purification process for serum-derived exosomes and evaluation of their regenerative capacity
… but contain contaminating lipoproteins. Our new isolation technique isolated purer serum exosomes that retained cell proliferation stimulation and potentially enhanced an in vivo angiogenic response. This approach should render the isolated exosomes more suitable for biomarker discovery, …

Seismic performance assessment of quasi-isolated highway bridges with seat-type abutments
"Seismic isolation is one of the most popular strategies to protect civil engineering structures against earthquake hazards. For highway bridges, isolation physically decouples a bridge superstructure from its substructures resting on a shaking ground, leading to a significant reduction in the …

Novel Time-Integrated Quantification of Sediment-Associated Fecal Indicator Bacteria in Rural Alabama Creek with Straight Pipes
… a novel, simple two-step centrifugation-based isolation method. This isolation method was most effective at the 35 °C incubation temperature, which yielded an average of 38.7% sediment-associated E. coli across sampling sites.The results of this study indicate initial flush events are the most …

Characterization of swimming motility in a marine unicellular cyanobacterium
… was investigated. A variety of analytical techniques confirmed that these strains swam through liquids without flagella or flagellar-like appendages. No extracellular structures were observed in a broad range of cell preparations examined by transmission electron microscopy (TEM), or by …

Phenotypic and biochemical characterisation of the causal agent of bacterial leaf streak of maize
… surface sterilised thoroughly before bacterial isolation commenced. Sections of the infected maize leaves were placed on GYC agar plates on which yellow, mucoid bacterial colonies after incubation for 24 to 48 hrs. The isolated bacteria were purified and the molecular identification of the …

The Relationship Between DNA's Physical Properties and the DNA Molecule's Harmonic Signature, and Related Motion in Water--A Computational Investigation
… frequencies. A brief look at a future possible isolation technique, wavelet analysis, was conducted. Finally, because these results are dependent on the tools at our disposal and hence by no means conclusive, suggestions for future research to expand on and further test these hypothesis are made …
