Soybean Seed Protein, Oil, Fatty Acids, and Isoflavones Altered by Potassium Fertilizer Rates in the Midsouth

Previous research has shown that the effect of potassium fertilizer on soybean ([Glycine max (L.) Merr. ] seed composition (protein, oil, fatty acids, and isoflavones) is still largely unknown. Therefore, the objective of this research was to investigate the effects of potassium application on seed protein, oil, fatty acids, and isoflavones under Midsouth environmental conditions. A three-year experiment was conducted in two locations (Milan, TN and Jackson, TN). Potassium (K) rates were applied in the form of K2O at a rate of 0 (Control, C), 45 (T1), 90 (T2), 134 (T3), and 179 (T4) kg·ha-1 in a randomized complete block design. The results showed that increasing the K application rate did not result in consistent effects on yield. However, increasing K application rate did increase protein, oleic acid, and individual and total isoflavone concentrations at both locations in 2008 and 2009. In Jackson in 2010, the increase of K rate did not change oleic acid, but resulted in an increase in glycitein and genistein isoflavone concentrations. In 2010, increasing K application rate increased protein concentrations, decreased individual and total isoflavones, and did not change oleic acid concentration at Milan. At the highest rate of K, 179 kg·ha-1, yield and some seed composition constituents were negatively impacted. Generally, K concentration in leaves at V5, R1, R3, and seed at harvest maturity stage (R8) increased with the increase of K rate applications. The research demonstrated that K application can alter seed composition, but this alteration depended on location, environmental stress factors, mainly heat and drought, K level in soil, and K application rate. Higher rates of K application may negatively impact seed composition constituents.
Adrenarche: changing adrenal response to adrenocorticotropin.

We have tested the hypothesis that adrenarche results from an altered biosynthetic response to ACTH. Adrenarche is the maturational increase in the production of adrenal 17-ketosteroids, particularly dehydroepiandrosterone (DHA) and DHA-sulfate (DHAS). Apparent steroidogenic efficiency was estimated from relationships between plasma steroid intermediates after administering ACTH-(l–24). ACTH testing was performed after giving a bedtime dose of dexamethasone to suppress the early morning ACTH surge. Three groups of patients were studied: 6 prepubertal children, 10 females with isolated adrenarche, and 8 normal adult females in the follicular phase of their menstrual cycles. Prepubertal DHAS was 11, adrenarchal 105, and adult 208 μg/dl. Adults had 5-fold greater DHA and about 2-fold greater androstenedione (AD) and 17-hydroxyprogesterone (17-PROG) than prepubertal children. Overnight dexamethasone suppression led to reduction of most steroids in most groups. Thirty minutes after a 10-eg ACTH bolus, prepuber.
A Modal-Based Real-Time Piano Synthesizer

This paper presents a real-time piano synthesizer where both the transverse and longitudinal motion of the string is modeled by modal synthesis, resulting in a coherent and highly parallel model structure. The paper applies recent developments in piano modeling and focuses on the issues related to practical implementation (e.g., numerical stability, aliasing, and efficiency). A strong emphasis is given to modeling nonlinear string vibrations, and a new variation of earlier synthesis techniques is proposed which is particularly well suited for modal synthesis. For soundboard modeling, the possibilities of using fast Fourier transform-based fast convolution and parallel second-order filters are discussed. Additionally, the paper describes the details of the software implementation and discusses the computational complexity of each model block. The piano model runs on current computer hardware with full polyphony in real time.
A note on the Fekete-Szegö problem for close-to-convex functions with respect to convex functions

We discuss the sharpness of the bound of the Fekete–Szegö functional for close-to-convex functions with respect to convex functions. We also brieﬂy consider other related developments involving the Fekete–Szegö functional | a 3 − λa 22 | (0 6 λ 6 1) as well as the corresponding Hankel determinant for the Taylor–Maclaurin coeﬃcients { a n } n ∈ Nr { 1 } of normalized univalent functions in the open unit disk D , N being the set of positive integers.
Experimental study of 3D contactless conductivity detection using microwave radiometry: a possible method for investigation of brain conductivity fluctuations

The capability of detecting electrical conductivity variations using focused microwave radiometry, a method used in clinical applications for temperature distribution imaging of subcutaneous tissues, is discussed in the present study. A novel microwave radiometric system operating at 3.5 GHz, including an ellipsoidal conductive wall cavity, which provides the required beamforming and focusing, is developed. The system is capable of providing distribution measurements of the product of conductivity and temperature of any object being at a temperature above the absolute zero. The implemented experimental procedure is based on the results of an electromagnetic numerical analysis using a semianalytical method which was developed in order to compute the focusing properties of the ellipsoidal reflector. Each measurement is realized by placing the region of interest in the area of the first focus of the cavity and collecting the radiation converged at the second by an almost isotropic dipole antenna connected to a sensitive radiometer. Experimental data from cylindrical shaped saline or de-ionized water filled tank phantoms in which saline solutions of different concentrations were infused, provide promising results concerning the system's ability of detecting conductivity variations. Future research is needed in order to elucidate the potential of the proposed methodology to be used for brain conductivity measurements.

Epipodophyllotoxin‐related leukemia. Identification of a new subset of secondary leukemia

Thirty‐seven children and adults who developed acute nonlymphocytic leukemia after the administration of chemotherapy that included etoposide or teniposide for a variety of hematologic and solid malignancies were identified. The secondary leukemia that occurred in these patients could be distinguished from the secondary leukemia that occurs after treatment with alkylating agents by the following: a shorter latency period; a predominance of monocytic or myelomonocytic features; and frequent cytogenetic abnormalities involving 11q23. Patients receiving an epipodophyllotoxin are at risk for developing secondary leukemia that has features distinct from the syndrome of secondary leukemia associated with alkylating agents.
The sources of moral motivation : studies on empathy, guilt, shame and values

This study had two main goals: to analyze the forms of emotional reaction tendencies that are likely to motivate moral behaviors, and to find correlates for these emotional tendencies. In study 1, students’ autobiographical narratives of guilt or shame experiences were analyzed. The results showed that pure shame was more likely to motivate avoidance instead of reparation, whereas guilt and combination of guilt and shame were likely to motivate reparation. However, all types of emotion could lead to chronic rumination if the person was not clearly responsible for the situation. Study 2 focused on the connection between guilt and empathy. The relations of empathy with two measures of guilt were examined in a sample of 13to 16-year-olds (N=113). Empathy was measured using Davis’s IRI and guilt by Tangney’s TOSCA and Hoffman’s semi-projective story completion method that includes two different scenarios, guilt over cheating and guilt over inaction. Empathy correlated more strongly with both measures of guilt than the two measures correlated with each other. Hoffman’s guilt over inaction was more strongly associated with empathy measures in girls than in boys, whereas for guilt over cheating the pattern was the opposite. Girls and boys who describe themselves as empathetic may emphasize different aspect of morality (justice vs. caring) and therefore possibly feel guilty in
Enhancement of Visual Motion Detection Thresholds in Early Deaf People

In deaf people, the auditory cortex can reorganize to support visual motion processing. Although this cross-modal reorganization has long been thought to subserve enhanced visual abilities, previous research has been unsuccessful at identifying behavioural enhancements specific to motion processing. Recently, research with congenitally deaf cats has uncovered an enhancement for visual motion detection. Our goal was to test for a similar difference between deaf and hearing people. We tested 16 early and profoundly deaf participants and 20 hearing controls. Participants completed a visual motion detection task, in which they were asked to determine which of two sinusoidal gratings was moving. The speed of the moving grating varied according to an adaptive staircase procedure, allowing us to determine the lowest speed necessary for participants to detect motion. Consistent with previous research in deaf cats, the deaf group had lower motion detection thresholds than the hearing. This finding supports the proposal that cross-modal reorganization after sensory deprivation will occur for supramodal sensory features and preserve the output functions.
Bioenergetic and Functional Consequences of Bone Marrow-Derived Multipotent Progenitor Cell Transplantation in Hearts With Postinfarction Left Ventricular Remodeling

Background— The present study examined whether transplantation of adherent bone marrow-derived stem cells, termed pMultistem, induces neovascularization and cardiomyocyte regeneration that stabilizes bioenergetic and contractile function in the infarct zone and border zone (BZ) after coronary artery occlusion. Methods and Results— Permanent left anterior descending artery occlusion in swine caused left ventricular remodeling with a decrease of ejection fraction from 55±5.6% to 30±5.4% (magnetic resonance imaging). Four weeks after left anterior descending artery occlusion, BZ myocardium demonstrated profound bioenergetic abnormalities, with a marked decrease in subendocardial phosphocreatine/ATP (31P magnetic resonance spectroscopy; 1.06±0.30 in infarcted hearts [n=9] versus 1.90±0.15 in normal hearts [n=8; P<0.01]). This abnormality was significantly improved by transplantation of allogeneic pMultistem cells (subendocardial phosphocreatine/ATP to 1.34±0.29; n=7; P<0.05). The BZ protein expression of creatine kinase-mt and creatine kinase-m isoforms was significantly reduced in infarcted hearts but recovered significantly in response to cell transplantation. MRI demonstrated that the infarct zone systolic thickening fraction improved significantly from systolic “bulging” in untreated animals with myocardial infarction to active thickening (19.7±9.8%, P<0.01), whereas the left ventricular ejection fraction improved to 42.0±6.5% (P<0.05 versus myocardial infarction). Only 0.35±0.05% donor cells could be detected 4 weeks after left anterior descending artery ligation, independent of cell transplantation with or without immunosuppression with cyclosporine A (with cyclosporine A, n=6; no cyclosporine A, n=7). The fraction of grafted cells that acquired an endothelial or cardiomyocyte phenotype was 3% and ≈2%, respectively. Patchy spared myocytes in the infarct zone were found only in pMultistem transplanted hearts. Vascular density was significantly higher in both BZ and infarct zone of cell-treated hearts than in untreated myocardial infarction hearts (P<0.05). Conclusions— Thus, allogeneic pMultistem improved BZ energetics, regional contractile performance, and global left ventricular ejection fraction. These improvements may have resulted from paracrine effects that include increased vascular density in the BZ and spared myocytes in the infarct zone.
The ‘brave’ man in the early years (0–8): defining the ‘role model’

The call for more ‘brave’ male early years practitioners and primary classroom teachers remains prevalent as boys’ underachievement continues to dominate education agendas. There is a recognised need, backed by government policy and public discourse in England, for more men to work in settings and schools (0–11) and act as ‘role models’. This article reports on the complexities of this as a term by presenting select findings from the author's doctoral research. Through an investigation into the thoughts and perceptions of men who actively work with children in the 0–8 sector, research findings suggest that there is a general lack of clarity with regard to how the ‘role model’ is actually defined. The significance of this will be considered.
The relations between self-determination, achievement motivation and academic achievement

This study's aim was to investigate whether self-determined behaviour and achievement motivation impact learner's academic performance. Convenient geographic sampling was used to select three pnmary schools in Soshanguve. A likert type questionnaire was used to collect data from 120 learners. Item analyses were preformed to investigate the reliability of subscales. Three hypotheses were tested using analysis of variance and Pearson product moment correlations. The first, which predicted that intrinsic motivation is positively related to academic achievement, was not supported. Both intrinsically and extrinsically motivated learners achieved better in academic tasks than amotivated learners. The second, which predicted a negative correlation between extrinsic motivation extrinsic motivation and academic performance, was also not supported. The third, which predicted that there is a negative correlation between amotivation and academic performance, was confirmed. General conclusions, recommendations, and limitations of the study are discussed.
Potential role of oxidative exoenzymes of the extremophilic fungus Pestalotiopsis palmarum BM-04 in biotransformation of extra-heavy crude oil

Large amount of drilling waste associated with the expansion of the Orinoco Oil Belt (OOB), the biggest proven reserve of extra‐heavy crude oil (EHCO) worldwide, is usually impregnated with EHCO and highly salinized water‐based drilling fluids. Oxidative exoenzymes (OE) of the lignin‐degrading enzyme system (LDS) of fungi catalyse the oxidation of a wide range of toxic pollutants. However, very little evidences on fungal degradation or biotransformation of EHCO have been reported, which contain high amounts of asphaltenes and its biodegradation rate is very limited. The aims of this work were to study the ability of Pestalotiopsis palmarum BM‐04 to synthesize OE, its potential to biotransform EHCO and to survive in extreme environmental conditions. Enzymatic studies of the LDS showed the ability of this fungus to overproduce high amounts of laccase (LACp) in presence of wheat bran or lignin peroxidase (LIPp) with EHCO as sole carbon and energy source (1300 U mgP−1 in both cases). FT‐IR spectroscopy with Attenuated Total Reflectance (ATR) analysis showed the enzymatic oxidation of carbon and sulfur atoms in both maltenes and asphaltenes fractions of biotreated EHCO catalysed by cell‐free laccase‐enriched OE using wheat bran as inducer. UV‐visible spectrophotometry analysis revealed the oxidation of the petroporphyrins in the asphaltenes fraction of biotreated EHCO. Tolerance assays showed the ability of this fungus to grow up to 50 000 p.p.m. of EHCO and 2000 mM of NaCl. These results suggest that P. palmarum BM‐04 is a hopeful alternative to be used in remediation processes in extreme environmental conditions of salinity and EHCO contamination, such as the drilling waste from the OOB.
Memory after silent stroke

Objective: Memory decline commonly occurs among elderly individuals. This observation is often attributed to early neurodegenerative changes in the hippocampus and related brain regions. However, the contribution of vascular lesions, such as brain infarcts, to hippocampal integrity and age-associated memory decline remains unclear. Methods: We studied 658 elderly participants without dementia from a prospective, community-based study on aging and dementia who received high-resolution structural MRI. Cortical and subcortical infarcts were identified, and hippocampal and relative brain volumes were calculated following standard protocols. Summary scores reflecting performance on tasks of memory, language, processing speed, and visuospatial function were derived from a comprehensive neuropsychological battery. We used multiple regression analyses to relate cortical and subcortical infarcts, hippocampal and relative brain volume, to measures of cognitive performance in domains of memory, language, processing speed, and visuospatial ability. Results: Presence of brain infarcts was associated with a smaller hippocampus. Smaller hippocampus volume was associated with poorer memory specifically. Brain infarcts were associated with poorer memory and cognitive performance in all other domains, which was independent of hippocampus volume. Conclusions: Both hippocampal volume and brain infarcts independently contribute to memory performance in elderly individuals without dementia. Given that age-associated neurodegenerative conditions, such as Alzheimer disease, are defined primarily by impairment in memory, these findings have clinical implications for prevention and for identification of pathogenic factors associated with disease symptomatology.
Cytomegalovirus protein substrates are not cleaved by the herpes simplex virus type 1 proteinase

The herpesvirus maturational proteinase, assemblin, is made as a precursor that undergoes at least two autoproteolytic cleavages--one in a sequence toward its carboxyl end, called the maturational (M) site, and one in a sequence toward its midpoint, called the release (R) site. The M- and R-site sequences are both well conserved among the herpesvirus proteinase homologs, suggesting that the proteinase of one herpesvirus might be able to cleave the substrates of another. To test this possibility, we cloned and expressed in human cells the long (i.e., full-length open reading frame of proteinase gene) and short (i.e., proteolytic domain, assemblin) forms of the proteinase from human and simian cytomegalovirus (HCMV and SCMV, respectively) and from herpes simplex virus type 1 (HSV-1), as well as the genes for their respective assembly protein precursor substrates. Data from cotransfections of these proteinase genes with appropriate homologous and heterologous substrates showed that although the SCMV and HCMV enzymes cleaved the M-sites of the assembly protein substrates of all three viruses and an SCMV R-site substrate, the HSV-1 proteinase cleaved only its own substrate. This finding demonstrates that the substrate specificity properties of the HSV-1 enzyme differ from those of the two CMV enzymes.
Subtleties in Tolerating Correlated Failures in Wide-area Storage Systems

High availability is widely accepted as an explicit requirement for distributed storage systems. Tolerating correlated failures is a key issue in achieving high availability in today's wide-area environments. This paper systematically revisits previously proposed techniques for addressing correlated failures. Using several real-world failure traces, we qualitatively answer four important questions regarding how to design systems to tolerate such failures. Based on our results, we identify a set of design principles that system builders can use to tolerate correlated failures. We show how these lessons can be effectively used by incorporating them into IrisStore, a distributed read-write storage layer that provides high availability. Our results using IrisStore on the PlanetLab over an 8-month period demonstrate its ability to withstand large correlated failures and meet preconfigured availability targets.
Brewing service quality in higher education

Purpose – The paper seeks to explore the influences of service quality in higher education and the perceptions associated with the implementation of a Singapore tertiary institution. It draws on the underpinnings of SERVQUAL, and discusses the dichotomy and interrelation between customer perception and expectation.Design/methodology/approach – Qualitative methodology was employed and data were collected by means of structured in‐depth interviewing with both internal (18 academics and ten current students) and external samples (ten graduates and five industry representatives). Content analysis was utilized to examine three key aspects of service standards: customer orientation, course design/delivery, and support services.Findings – The way students are perceived, whether as customers or products, will have an influence on the type of learning dynamics that develop both within and outside the classroom. Service quality, therefore, needs to be evaluated based on an integrated experience which occurs in a ne.
Personality Profiles of U.S. Navy Sea-Air-Land (SEAL) Personnel

Abstract : One hundred thirty-nine U.S. Navy Sea-Air-Land (SEAL) personnel completed the NEO Personality Inventory (NEO-PI) . The average profiles were compared to adult male norms for five broadly defined domains. SEALs scored lower in Neuroticism and Agreeableness, average in Openness, and higher in Extraversion and Conscientiousness compared to these two populations. High Extraversion and conscientiousness scores have been shown to predict job performance in other professions. SEALs seek excitement and dangerous environments, but are otherwise stable, calm, and rarely reckless or impulsive. Although this average profile may not characterize any individual SEAL, we believe this study provides the most comprehensive personality profile of Navy SEALs to date.
