A 62-year-old female presenting with anemia and extensive hemorrhages is reported. Coagulation tests showed significantly prolonged prothrombin time (PT) and activated partial thromboplastin time. Decreased levels of clotting factor X activity were determined (5.4%). Bone marrow biopsy revealed neoplastic plasma cells. Serum and urine protein electrophoresis were both negative for monoclonal gammopathy, and both bone marrow and abdominal fat biopsies were negative for amyloid deposition. The patient was diagnosed as suffering from nonsecretory multiple myeloma (MM) complicated by acquired factor X deficiency...

A Wickeramomyces anomalus biofilm supported on wood husk was used to remediate water bodies contaminated with chromium (Cr), in batch and open systems. The favorable adhesion ability of the chromium-resistant yeast strain on the wood husk was predicted by XDLVO theory and confirmed by environmental scanning electronic microscopy. The chromium decontamination was then optimized in a batch mode using a central composite design (CCD). Analysis of variance (ANOVA) showed a high coefficient of determination (R2 ) value of 0...

The present study was conducted to assess the possible impacts of human activities and naturally occurring on the marine sediments, to test for anomalous enrichments in metals. A total of 32 marine sediments samples collected from 12 coastal areas of the Egyptian Red Sea analyzed using different analytical techniques. The analysis explored 43 elements for the marine sediments. Principal component analysis and multivariate statistics were implemented on the data. The extent of pollution was quantified for selected 6 pollutants using the geoaccumulation indices (Igeo ), enrichment factor (EF), metal pollution index (MPI), contamination factor (Cf ), and degree of contamination factor (Cd )...

BACKGROUND: Although cardio-respiratory (CR) system is generally controlled by the autonomic nervous system, interactions between the cortex and these primary functions are receiving an increasing interest in neurosciences. NEW METHOD: In general, the timing of such internally paced events (e.g. heartbeats or respiratory cycles) may display a large variability. For the analysis of such CR event-related EEG potentials, a baseline must be correctly associated to each cycle of detected events...

As a fast-developing technique for in situ multi-element analysis method, laser induced breakdown spectroscopy - LIBS is, however, developing slowly on liquid analysis due to some technical difficulties. We propose a new method, namely capillary mode, to quantify the concentrations of the elements in solution using LIBS. A Nd:YAG laser with repetition of 10 Hz were used to analyze the solution of Na2 CrO4 and no any sample preparation in measurements. The experimental results show that the splashing of liquid induced by laser pulses is decreased significantly and the pollution of mirrors is avoided effectively using liquid capillary mode...

States continue to rely on conditional release (CR) as an effective and cost-effective way to manage individuals found not guilty by reason of insanity (NGRI). Research has demonstrated that insanity acquittees returning to the community have low recidivism rates and moderately low revocation rates. This study followed 238 individuals found NGRI in Oregon who were evaluated with the Historical, Clinical, Risk-20 (HCR-20; Webster, Douglas, Eaves, & Hart, 1997) and placed in the community on CR. The majority of individuals on CR (n = 157, 66%) maintained their release throughout the entire follow-up period (between 4 and 9 years), but 81 (33...

Facilities for heavy ion therapies are steadily increasing in number worldwide. One of the advantages of heavy ions is their high relative biological effect (RBE). In a model used at NIRS (National Institute of Radiological Sciences), linear energy transfer (LET) spectra are required to estimate biological dose (physical dose × RBE). The CR-39 plastic charged-particle detector (CR-39) is suitable for measurement of LET. For the present study, done at the Gunma University Heavy Ion Medical Center (GHMC), we measured LET spectra at 11 depths in spread-out Bragg peak (SOBP) irradiation by a 12C beam of 380 MeV/u...

The Shayinghe River is an important tributary of the Huaihe River in China. The concentrations of potential toxic elements (PTEs), such as As, Hg, Pb, Cu, Zn, Cr, and Cd in soils and dominant vegetation from mud-dumping areas reclaimed with dredged sediments, and areas without mud-dumping (non-mud-dumping areas) adjacent to the Shayinghe River were investigated. The potential ecological risk index (ERI) and transfer coefficient (TC) were calculated and evaluated. The results showed that the potential toxic element concentrations in all sampling areas decreased in the order of (Zn, Cr) > (Cu, Pb) > As>Cd > Hg...

The primary objective of this work was to enhance the performance and emission of the computerized variable compression ratio (VCR) diesel engine fuelled with pentanol/Calophyllum inophyllum (CI)/diesel fuel blends. Based on the prerequisite for the current research, response surface methodology (RSM), an optimization technique, was adopted for the process parameters compression ratio (CR), load and fuel blends, and the optimized responses like brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), oxides of nitrogen (NOx ), carbon monoxide (CO), carbon dioxide (CO2 ), hydrocarbon (HC), and smoke were revealed with the help of Derringer's desirability approach...

High entropy alloys based on 3d transition metals display rich and promising magnetic characteristics for various high-technology applications. Understanding their behavior at finite temperature is, however, limited by the incomplete experimental data for single-phase alloys. Here we use first-principles alloy theory to investigate the magnetic structure of polymorphic CoCrFeMnNi in the paramagnetic state by accounting for the longitudinal spin fluctuations (LSFs) as a function of temperature. In both face-centered cubic (fcc) and hexagonal close-packed (hcp) structures, the LSFs induce sizable magnetic moments for Co, Cr and Ni...

Yinma River is a typical river in the major Phaeozems zone of Northeast China. It has been suffering an increasing environmental pressure from heavy metal contamination due to the rapid development of population, social-economy and urbanization as well as long term over cultivation. This study investigated the spatial distribution, chemical fraction of heavy metals (Cu, Pb, Zn, Cr, Cd, Ni, As, and Hg) in sediments of Yinma River based on BCR procedure, assessed the contamination level, and identified their sources via multivariate statistical analysis...

Electronic waste (e-waste) is the fastest growing solid waste stream worldwide and mostly ends up in developing countries where residents use primitive methods for recycling. The most infamous e-waste recycling town, Guiyu in Southeast China, has been recycling since the mid-1990s. E-waste contains several harmful chemicals, including lead (Pb), cadmium (Cd), chromium (Cr), and manganese (Mn). In 2011-12, the e-waste Recycling Exposures and Community Health (e-REACH) Study enrolled 634 pregnant women living in Guiyu and Haojiang, a control site, both in Shantou, China...

The effect of isothermal tempering on retained austenite decomposition and carbide precipitation were investigated in a medium-carbon low-alloy bainitic steel. High-resolution dilatometry was used to perform isothermal tempering at 350 °C, 550 °C and 600 °C for different holding times up to 16 h. The decomposition of retained austenite, morphology and composition of carbides were investigated by analyzing the dilatometric curves and were confirmed through scanning and transmission electron microscopy observations...
