Heterobostrychus hamatipennis Lesne (Coleoptera: Bostrichidae) new to Florida

Heterobostrychus hamatipennis Lesne, an oriental wood borer, is reported to be established in southeast Florida for the first time. This is the second member of the genus Heterobostrychus Lesne that has become established in Florida

Three bostrichid beetles new to Florida (Coleoptera: Bostrichidae)

Three species ofbostrichid beetles, previously unknown from Florida, were found in the Florida State Collection of Arthropods (FSCA) and in the Archbold Biological Station Collection. The genus Stephanopachys Waterhouse, in Florida, is now represented by four species. These new records probably represent infrequently collected species and not new introductions to Florida. Akey to all species of Stephanopachys adults from Florida is presented

Study of the vocabulary development in selected first grade readers

Because of the great number of new reading series now on the market, the writer was prompted to examine four recent reading series with respect to the similarities and differences in their vocabulary development. The study included the approach, or method, used to develop the vocabulary and also the type and load of vocabulary in each series

A Rapid Technique for Counting Cracks in Rocks

Using a scanning electron microscope (SEM) and an image analyzer, we have developed a technique for counting and measuring cracks in rocks which is more efficient than traditional techniques in which an operator performs all image analysis functions. The key aspect of the technique is that black-on-white tracings of fresh cracks, which can be made rather rapidly by an operator, are measured and digitized by an image analyzer. The most time-consuming step in the process has now become the generation of SEM micrographs and pertinent chemical (mineralogical) information, not the quantification of crack structure. The technique has been applied to two studies involving nuclear waste isolation in a granitic rock, Climax Stock (Nevada Test Site) quartz monzonite, a Cretaceous age rock which is structurally very inhomogeneous. One study detected a relationship between crack structure and distance from a hammer-drilled borehole; the other study was unable to detect a relationship between crack structure and gamma irradiation treatment in rocks loaded to near failure

Report on the feasibility of using isotopes to source and age-date groundwater in Orange County water district`s Forebay region

From March to September 1995, the Isotope Sciences Division of Lawrence Livermore National Laboratory performed isotopic measurements on water in the Orange County Forebay region. The goal was to test the applicability of isotope techniques for determining the current groundwater flow paths and flow rates in the OCWD spreading facilities. Successful results could then be used to predict the fate of proposed reclaimed waste water recharge. Stable isotope measurements in surface waters and groundwaters in the Forebay region of the Orange County groundwater basin provided a general source indicator. The data defined three general groups: (1) groundwater derived from recharged Santa Ana River water (SAR),(2) groundwater resulting from a mixture of recharged Colorado River water and the SAR, and (3) groundwater recharged from the Santiago basin area. In the first group of data, recharge directly from the SAR flow was not readily distinguishable from groundwater recharged via the spreading ponds. Some groundwater samples from Forebay wells showed significant temporal variability in stable isotope values, while others remained constant throughout the study period. The temporal changes in the groundwater stable isotope signatures are believed to be controlled by similar variations in the stable isotope signatures of the surface water recharge. With further sampling, these seasonal isotopic variations may provide a viable tracer for young (<2 years) groundwater

Hydrothermal interaction of solid wafers of Topopah Spring Tuff with J-13 water and distilled water at 90, 150, and 250{sup 0}C, using Dickson-type, gold-bag rocking autoclaves

The Nevada Nuclear Waste Storage Investigations Project has conducted experiments to study the hydrothermal interaction of rock and water representative of a potential high-level waste repository at Yucca Mountain, Nevada. The results of these experiments help define the near-field repository environment during and shortly after the thermal period that results from the emplacement of nuclear waste. When considered in conjunction with results contained in companion reports, these results can be used to assess our ability to accelerate tests using the surface area/volume parameter and/or temperature. These rock-water interaction experiments were conducted with solid polished wafers cut from both drillcore and outcrop samples of Topopah tuff, using both a natural ground water and distilled water as the reacting fluid. Pre- and post-test characterization of the reacting materials was extensive. Post-test identification and chemical analysis of secondary phases resulting from the hydrothermal interactions were aided by using monoliths of tuff rather than crushed material. All experiments were run in Dickson-type, gold-bag rocking autoclaves that were periodically sampled at in situ conditions. A total of nine short-term (up to 66-day) experiments were run in this series; these experiments covered the range from 90 to 250{sup 0}C and from 50 to 100 bar. The results obtained from the experiments have been used to evaluate the modeled results produced by calculations using the geochemical reaction process code EQ3/6. 31 refs., 37 figs., 7 tabs

The waveform correlation event detection system project, Phase I: Issues in prototype development and testing

A study using long-period seismic data showed that seismic events can be detected and located based on correlations of processed waveform profiles with the profile expected for an event. In this technique both time and space are discretized and events are found by forming profiles and calculating correlations for all time-distance points. events are declared at points with large correlations. In the first phase of the Waveform Correlation Event Detection System (WCEDS) Project at Sandia Labs we have developed a prototype automatic event detection system based on Shearer`s work which shows promise for treaty monitoring applications. Many modifications have been made to meet the requirements of the monitoring environment. A new full matrix multiplication has been developed which can reduce the number of computations needed for the data correlation by as much as two orders of magnitude for large grids. New methodology has also been developed to deal with the problems caused by false correlations (sidelobes) generated during the correlation process. When an event has been detected, masking matrices are set up which will mask all correlation sidelobes due to the event, allowing other events with intermingled phases to be found. This process is repeated until a detection threshold is reached. The system was tested on one hour of Incorporated Research Institutions for Seismology (IRIS) broadband data and built all 4 of the events listed in the National Earthquake Information Center (NEIC) Preliminary Determination of Epicenters (PDE) which were observable by the IRIS network. A continuous execution scheme has been developed for the system but has not yet been implemented. Improvements to the efficiency of the code are in various stages of development. Many refinements would have to be made to the system before it could be used as part of an actual monitoring system, but at this stage we know of no clear barriers which would prevent an eventual implementation of the system

Comprehensive Review of Acute Pancreatitis Pain Syndrome

Pancreatitis is a condition that causes inflammation in the pancreas, an organ located behind the stomach. This condition often presents as neuropathic, inflammatory, and/or visceral pain. Acute pancreatitis is typically characterized by sudden and severe abdominal pain, often in the upper right part of the abdomen. The pain from pancreatitis can be caused by different mechanisms, such as abnormal activation of pancreatic zymogens or NF-κB mediated inflammation in the pancreas. The treatment of pancreatitis depends on its type, severity, and underlying cause. Hospitalization and medications are typically necessary, while in others, surgery may be required. Proper management of pancreatitis is essential, as it can help reduce the risk of complications and improve the patient’s quality of life. The literature on pancreatitis pain management evaluates systematic approaches and the effectiveness of various treatments, such as lidocaine, opioid agonists, ketamine, magnesium, endoscopic methods, spinal cord stimulation, and other novel treatments present opportunities for exploration in pancreatitis pain management

Outcomes Following Abiraterone versus Enzalutamide for Prostate Cancer: A Scoping Review

Abiraterone acetate (AA) and enzalutamide (ENZ) are commonly used for metastatic prostate cancer. It is unclear how their outcomes and toxicities vary with patient-specific factors because clinical trials typically exclude patients with significant comorbidities. This study aims to fill this knowledge gap and facilitate informed treatment decision making. A registered protocol utilizing PRISMA scoping review methodology was utilized to identify real-world studies. Of 433 non-duplicated publications, 23 were selected by three independent reviewers. ENZ offered a faster and more frequent biochemical response (30-50% vs. 70-75%), slowed progression (HR 0.66; 95% CI 0.50-0.88), and improved overall survival versus AA. ENZ was associated with more fatigue and neurological adverse effects. Conversely, AA increased risk of cardiovascular- (HR 1.82; 95% CI 1.09-3.05) and heart failure-related (HR 2.88; 95% CI 1.09-7.63) hospitalizations. Ultimately, AA was associated with increased length of hospital stay, emergency department visits, and hospitalizations (HR 1.26; 95% CI 1.04-1.53). Accordingly, total costs were higher for AA, although pharmacy costs alone were higher for ENZ. Existing data suggest that AA and ENZ have important differences in outcomes including toxicities, response, disease progression, and survival. Additionally, adherence, healthcare utilization, and costs differ. Further investigation is warranted to inform treatment decisions which optimize patient outcomes

Richard Löwenherz im Museum : Menschen und Objekte in Bewegung

Irgendwo in unserem sogenannten Allgemeinwissen über das Mittelalter ist auch die Vorstellung verankert, dass das Leben früher ruhiger, gemütlicher und nicht so hektisch war wie heute. Früher, als die Welt noch ‚normal’ war, hatten die meisten Menschen einen festen Lebensmittelpunkt, waren fest verwurzelt in einer Gemeinschaft und verließen ihre Heimat nur dann, wenn es sich gar nicht vermeiden lies. Nur wenige – nämlich die besonders Überprivilegierten und die besonders Unterprivilegierten -, also die, die es sich leisten konnten oder die, die dazu gezwungen wurden, waren unterwegs. Alle anderen blieben ein Leben lang zuhause, an dem Ort, an dem sie ihren festen Lebensmittelpunkt hatten. Soweit unser intuitives Vorwissen darüber, wie es früher, also auch schon im Mittelalter, gewesen sein muss. Dieses mehr ‚gefühlte’ als wissenschaftlich erwiesene Vorwissen haben wir im Rahmen eines Hauptseminars zur Geschichte des Mittelalters im Herbst 2017 gründlich hinterfragt. Ausgangspunkt war die Ausstellung „Richard Löwenherz“, die im September am Historischen Museum der Pfalz in Speyer eröffnet wurde. Ein Seminar zum Thema führte uns auf die Spuren der im Museum gezeigten Objekte, von dort auf die Spuren der Menschen im Umfeld des berühmten Königs von England
