The possibilities for a SPAC in the Icelandic market
… Purpose Acquisition Companies, here after SPAC were possible in Iceland for Stoðir hf. NASDAQ Iceland introduced their new rules allowing for SPACs to be registered on the stock exchange. However, the reception of the idea is not as positive as one might think, especially comparing to the …

Der Einfluss von Plaquemorphologie und anderen prädiktiven Faktoren auf das Auftreten von Mikroembolien während der Stentgeschützten Perkutanen Angioplastie der Karotiden (SPAC)
… Perkutanen Angioplastie der Karotiden (SPAC). Diese gelten als Folge thrombembolischer Abscheidungen aus der Karotisplaque während der Intervention. Plaquezusammensetzung und morphologie spielen eine Rolle bei der Stabilität der Plaque und könnten damit einen prognostischen Marker für …

Water Transport in the Vadose Zone and Hydrological Processes in Soil-Plant-Atmosphere Continuum (SPAC) in West Texas, USA
… of the soil-plant-atmosphere continuum (SPAC) is still limited. In this study, water transport within the SPAC under a semi-arid climate, including rain infiltration and evaporation mechanisms, have been investigated by a combination of on-site monitoring of meteorological and soil water …

Advanced analysis of complex seismic waveforms to characterize the subsurface Earth structure
… Calabria slab, (2) Spatial Average Coherency (SPAC) analysis of microtremor to characterize the subsurface structure in urban areas, and (3) Surface wave dispersion inversion for shear wave velocity structure. Although these three projects apply different techniques and investigate different …

Mechanistic Investigations of Cyclase Enzymes Involved in Lantibiotic Biosynthesis
… in both subtilin and nisin biosynthesis, SpaC and NisC, respectively, contain stoichiometric amounts of zinc, implying a possible catalytic role. EXAFS analysis of SpaC suggests that two cysteines coordinate to the metal and possibly two histidines. The metal may function to activate the …

Innovative sustainable approaches for managing the soil and water resources in mediterranean agricultural context [Approcci innovativi e sostenibili per la gestione delle risorse del suolo e delle acque nel contesto agricolo mediterraneo]
… del sistema continuo suolo-pianta-atmosfera (SPAC), in termini di caratteristiche chimico fisiche del suolo, stato idrico delle colture e produttività delle stesse, e analisi dei flussi di anidride carbonica (CO2) dal suolo a diverse scale spaziali. In particolare, per l'analisi dei flussi di …

Seismic site characterization using broadband and DAS ambient vibration measurements on Mt Etna, Italy
… ratios and the spatial autocorrelation method (SPAC) have proven to be valuable tools to gain insight into local site effects by ambient noise measurements. Here, the two methods are employed to assess the subsurface velocity structure at the Piano delle Concazze area on Mt Etna. Volcanic tremor …

Investigations of the Mechanism and Substrate Scope of the Enzymes Involved in Lantibiotic Biosynthesis
… lantibiotic dehydratase, SpaB, and cyclase SpaC. The heterologously expressed and purified SpaS peptide was employed in assays with the purified SpaB and SpaC proteins to investigate conditions for the in vitro reconstitution of these proteins. The successful in vitro reconstitution of the …

Evaluation and implementation of adsorption technologies for the treatment of per and polyfluoroalkyl substances
… of super fine powdered activated carbon (SPAC) applied in a coupled ceramic microfiltration system. Adsorption performance of SPAC was found to be more than 480 times better than GAC in the treatment of perfluoroalkyl acids and polyfluorinated precursors in highly contaminated water from a …

Variable selection for high-dimensional complex data
… propose a new Semi-standard PArtial Covariance (SPAC) approach which is able to reduce correlation effects from other predictors while incorporating the magnitude of coefficients. The proposed SPAC variable selection is effective in choosing covariates which have direct association with the …

The crystal stucture determination of low and high temperature phases of Tris (Ethylene Terephthalate)
… were found to have a monoclinic unit cell and spac%C; the unit cell is a = 16.98A°, b = 19.59A °, c = 8.43A and $ 96.240 with z = 4 molecules/unit cell; d(obs) = 1.367 g/cm 3 . The HTP trimer crystals were formed from a hot solution of tris(ethylene terephthalate) and Dekalin above 1200C. These …

From Peptide Precursors to Lanthionine -Containing Peptide Antibiotics Using the First Isolated and Active Lacticin 481 Synthetase: Mechanistic Studies and Peptide Engineering
… in vitro reconstitution using the purified SpaB, SpaC, and the substrate SpaS was unsuccessful. As a result, the biosynthesis of lacticin 481 which employs one single modification enzyme presumably responsible for both dehydration and cyclization was investigated. Both the modification enzyme LctM …

AN EVALUATION OF THE LANGUAGE LEARNING OUTCOMES IN THE NEW ELEMENTARY SCHOOL CURRICULUM OF THE PHILIPPINES
… Due to time constraint and the pupils attention spac factor, the rests were reduced to a 35 item one hour test for each subject. The second try out was done in .November 1984 to another randomly selected group of 100 grade II pupils from the same try out school. The tests were again item …
