Demographic predictors of urinary arsenic in a low-income predominantly Hispanic pregnancy cohort in Los Angeles.

Background Arsenic (As) is a contaminant of top public health concern, due to its range of detrimental health effects. Arsenic exposure has not been well-characterized among the US Hispanic populations and has been particularly understudied in this population during pregnancy. Methods As part of the MADRES ongoing pregnancy cohort of predominantly lower-income, Hispanic women in Los Angeles, CA, we examined levels of maternal first trimester urinary As, including total As and As metabolites (inorganic (iAs), monomethylated (MMA) and dimethylated As (DMA)), in relation to participant demographics, lifestyle characteristics, and rice/seafood consumption, to identify factors that may influence As exposure and its metabolites during pregnancy (N = 241). Results Total As concentrations ranged from low to high (0.8-506.2 μg/L, mean: 9.0 μg/L, SD: 32.9) in our study population. Foreign-born Hispanic women had 8.6% higher %DMA (95% CI: 3.3%, 13.9%) and -7.7% lower %iAs (95% CI: -12.6%, -2.9%) than non-Hispanic women. A similar trend was observed for US-born Hispanic women. In addition, maternal age was associated with 0.4% higher %iAs (95% CI: 0.1%, 0.6%) and 0.4% lower %DMA (95% CI: -0.7%, -0.1%) per year, which may indicate poor As methylation capacity. Conclusion Individual factors may predict As exposure and metabolism in pregnancy, and in turn, greater risk of adverse health effects.
The impact of small-scale land cover and groundwater interactions on base flow solute and nutrient export in a small agricultural stream

Central Kentucky could be considered a critical source area of nutrients in water ways because of low permeability soils, fast groundwater flow through bedrock fractures, and pervasive agriculture and development. Of particular concern is rising development in rural areas, which creates mixed land cover (MLC) watersheds, i.e., watersheds with development, agriculture, and other land cover types. MLC watersheds add complexity to spatial and temporal releases of dissolved constituents, leading to less predictable water quality patterns. The goal of this research was to examine the export of dissolved substances from a small, upland MLC catchment in central Kentucky with a focus on how the interaction between discharges from developed agricultural land cover and groundwater influence base flow water quality. Our approach was to spatially sample a representative catchment monthly over 1 year, characterize the major dissolved constituents, and evaluate catchment processes with statistical analyses and Piper diagrams. Principal component analysis, factor analysis, and Piper diagrams indicate base flow was composed of groundwater influenced by two different host rocks and an outfall draining a developed region. Base flow nutrient export was dominated by mixing nitrate-sulfate rich groundwater with ammonium-phosphate-chloride rich outfall drainage. High nitrate groundwater dominated nitrogen export in the winter, whereas high ammonium outfall drainage dominated summer export. Spatial analysis revealed that ~ 10% of the basin may have similar land cover and hydrologic processes, suggesting that MLC catchments are small but collectively significant nitrogen sources to river networks due to development and agriculturally impacted groundwater.
Source type estimation using noble gas samples.

Abstract A Bayesian source-term algorithm recently published by Eslinger et al. (2019) extended previous models by including the ability to discriminate between classes of releases such as nuclear explosions, nuclear power plants, or medical isotope production facilities when multiple isotopes are measured. Using 20 release cases from a synthetic data set previously published by Haas et al. (2017), algorithm performance was demonstrated on the transport scale (400–1000 km) associated with the radionuclide samplers in the International Monitoring System. Inclusion of multiple isotopes improves release location and release time estimates over analyses using only a single isotope. The ability to discriminate between classes of releases does not depend on the accuracy of the location or time of release estimates. For some combinations of isotopes, the ability to confidently discriminate between classes of releases requires only a few samples.

Associations between parenting representations and behavior among young mothers and mothers with opioid use disorder.

Mothers' representations reflect how they experience their child and their relationship, and can guide parenting behavior. While studies of representations typically focus on infancy, this study examines associations between mothers' representations and behavior with their preschoolers using two samples: young mothers (n = 201; 42% African American, 42% Latina, 8% European-American, 8% multi-ethnic; Mage = 32 months) and mothers in treatment for opioid use disorder (OUD; n = 150; 100% African American; Mage = 49 months). This study aims to identify the distribution of representations within these populations, differences in parenting between mothers classified with balanced and non-balanced representations, and distinct parenting behaviors associated with distorted and disengaged representations. The Working Model of the Child Interview was conducted to assess representations, and mother-child interactions were video-recorded. The distribution of balanced, distorted, and disengaged representations was 59%, 25%, and 15% among young mothers, and 21%, 39%, and 40% among mothers with OUD. Balanced representations (coherent, rich, engaged, respectful) were associated with positive parenting, including sensitivity, autonomy support, cognitive support and less negative regard among young mothers, and sensitivity and encouragement in the OUD sample. Mothers with disengaged representations (emotionally distant, lacking detail, indifferent) demonstrated less support for learning compared to mothers with distorted representations (involved but inconsistent, negative, or bizarre descriptions of child).
Microwave synthesis of single-phase nanoparticles made of multi-principal element alloys

Metal nanoparticles of multi-principal element alloys (MPEA) with a single crystalline phase have been synthesized by flash heating/cooling of nanosized metals encapsulated in micelle vesicles dispersed in an oil phase (e.g., cyclohexane). Flash heating is realized by selective absorption of a microwave pulse in metals to rapidly heat metals into uniform melts. The oil phase barely absorbs microwave and maintains the low temperature, which can rapidly quench the high-temperature metal melts to enable the flash cooling process. The precursor ions of four metals, including Au, Pt, Pd, and Cu, can be simultaneously reduced by hydrazine in the aqueous solution encapsulated in the micelle vesicles. The resulting metals efficiently absorb microwave energy to locally reach a temperature high enough to melt themselves into a uniform mixture. The duration of microwave pulse is crucial to ensure the reduced metals mix uniformly, while the temperature of oil phase is still low to rapidly quench the metals and freeze the single-phase crystalline lattices in alloy nanoparticles. The microwave-enabled flash heating/cooling provides a new method to synthesize single-phase MPEA nanoparticles of many metal combinations when the appropriate water-in-oil micelle systems and the appropriate reduction reactions of metal precursors are available.

Connecting collections and cultures by creating a community of children's librarians around early literacy storytimes

Communities of practice are important tools for professional development, encouraging peer-to-peer learning and knowledge creation. This study, which is part of a three-year Institute for Museum and Library Services National Leadership Research Grant, examined children's librarians’ perceptions of a community of practice they created during an extended online, interactive training program. The librarians shared both positive and negative perceptions of the community that was created during the training. Through the interviews it became apparent that while creating a community of practice the librarians made connections between their collections and shared their library cultures.
Recent Trends in Workflow Management Products, Standards and Research

In the last few years, workflow management (WFM) has been the focus of intense activity in terms of products, standards and research work worldwide. Work in many areas of computer science impacts workflow management. Many workflow companies and research groups are in existence now. Several conferences and workshops are being held regularly. In this paper, I briefly summarize the recent trends in WFM products, standards and research. I address technical as well as business trends.
Student Ethical Perceptions and Ethical Action Propensities: An Analysis of Situation Familiarity

Recently McCuddy and Peery (1996) have suggested that business students may not respond the same way to “unfamiliar” business ethical dilemmas as they would to more “familiar” academic ethical dilemmas. The purpose of this study was to present the same students with both “unfamiliar” business dilemmas as well as possibly more “familiar” academic dilemmas in order to examine this issue.
Preparation, purification, and characterization of a reversibly lipidized desmopressin with potentiated anti-diuretic activity.

Purpose. To prepare and characterize a reversibly lipidized dipalmitoyl desmopressin (DPP), and to compare its anti-diuretic efficacy and biodistribution with that of unmodified desmopressin (DDAVP).
Yoga for generalized anxiety disorder: design of a randomized controlled clinical trial

Generalized anxiety disorder (GAD) is a common disorder associated with significant distress and interference. Although cognitive behavioral therapy (CBT) has been shown to be the most effective form of psychotherapy, few patients receive or have access to this intervention. Yoga therapy offers another promising, yet under-researched, intervention that is gaining increasing popularity in the general public, as an anxiety reduction intervention. The purpose of this innovative clinical trial protocol is to investigate the efficacy of a Kundalini Yoga intervention, relative to CBT and a control condition. Kundalini yoga and CBT are compared with each other in a noninferiority test and both treatments are compared to stress education training, an attention control intervention, in superiority tests. The sample will consist of 230 individuals with a primary DSM-5 diagnosis of GAD. This randomized controlled trial will compare yoga (N=95) to both CBT for GAD (N=95) and stress education (N=40), a commonly used control condition. All three treatments will be administered by two instructors in a group format over 12 weekly sessions with four to six patients per group. Groups will be randomized using permuted block randomization, which will be stratified by site. Treatment outcome will be evaluated bi-weekly and at 6month follow-up. Furthermore, potential mediators of treatment outcome will be investigated. Given the individual and economic burden associated with GAD, identifying accessible alternative behavioral treatments will have substantive public health implications.

Essential and Perceptual Attributes of Words in Reflective and On-line Processing

Access to essential and perceptual attributes of word meanings was investigated in a series of tasks. First, perceptual attributes of a number of natural kind concepts were determined by asking participants to generate the most salient features of those concepts; they were asked to assess the importance of both those features and features that fit criteria for essential attributes. Attributes fitting the criteria for essential attributes were found to be judged more important than perceptual attributes in identifying an object and to have more connections to other attributes of the concept. Semantic priming for both types of features was then investigated. Prime-target pairs consisting of the natural kind concept term and the perceptual or essential attribute were presented for lexical decision (Experiments 1a and 1b) or naming (Experiments 2a and 2b). Interstimulus intervals were either 0 or 200 ms. Both types of features were primed at a 200 ms interstimulus interval but only in the lexical decision task.
Copper and ceruloplasmin activity in human amniotic fluid

The variation in the level of copper and ceruloplasmin oxidase activity in human amniotic fluid from 20 weeks' gestation to term was reported. The protein content of amniotic fluid decreased toward term. A definite decreasing trend of concentration of copper, expressed both as nanograms of copper per milliliter of amniotic fluid and nanograms of copper per milligram of protein, was also observed from midgestation toward term. Ceruloplasmin, on the other hand, demonstrated a significant increase from the period 20 38 weeks' gestation, with a subsequent decline after 38 weeks.
Health information seeking of low socioeconomic status Hispanic adults using smartphones

Purpose – Smartphones have great potential to bridge the digital divide that low-socioeconomic status (SES) Hispanics have been experiencing. However, little is known about this group’s use of smartphones for health information. The purpose of this paper is to fill the gap by exploring the context in which smartphones were used for health information. Design/methodology/approach – The authors interviewed 20 low-SES Hispanic participants using the semi-structured interview method. Participants had not obtained college degrees and had annual incomes less than $30,000, but had used their smartphones for health information. The interviews were transcribed and analyzed using the qualitative content analysis method. Findings – Being economical was an important reason for low-SES Hispanic users to use smartphones for health information. The users relied heavily on public Wi-Fi to access the internet. They searched a wide range of health topics, mostly using the mobile web rather than apps. They lacked knowledge ...
Chorea Associated with High Titers of Antiphospholipid Antibodies in the Absence of Antiphospholipid Antibody Syndrome

Background : Chorea associated with high titers of antiphospholipid antibodies in the absence of antiphospholipid antibody syndrome has been seldom reported. Case report : An 89-year-old female developed persistent right side chorea associated with high titers of anticardiolipin antibody(antiphospholipid antibosies immunoglobulin(Ig)M, 45 MPL and 112 IgM aCL(MPL) after 3 months) but normal lupus anticoagulants. Her magnetic resonance imaging(MRI) showed no abnormality, but positron emission tomography(PET) demonstrated increased bilateral striatal metabolic activity, more on the left side. Her MRI showed no cause for chorea. The PET scan demonstrated a marked increase in the metabolic activity of the left basal ganglia. Discussion : Her chorea remained unchanged over a 9-month follow-up period. The literature on chorea associated with high titers of antiphospholipid antibodies in the absence of antiphospholipid syndrome is reviewed.

Chronic Kidney Disease and Related Long-Term Complications After Liver Transplantation

Liver transplantation is the standard of care for patients with decompensated cirrhosis. Liver transplantation recipients have excellent short-term and long-term outcomes including patient and graft survival. Since the adoption of model for end-stage liver disease (MELD)-based allocation policy, the incidence of post-transplant end stage renal disease has risen significantly. Occurrence of Stage 4 chronic kidney disease and end stage renal disease substantially increases the risk of post-transplant deaths. Because majority of late post-transplant mortality is due to nonhepatic post-transplant comorbidities, personalized care directed toward risk factor modification may further improve post-transplant survival.

Adenomyosis: symptoms, histology, and pregnancy terminations.

Objective: To correlate symptoms of uterine adenomyosis with histopathologic features. Methods: One hundred eleven specimens of uteri and cervices that weighed under 280 g were reevaluated. When adenomyosis was identified, assessment included depth of adenomyotic foci, graded as deep (above 80%), intermediate (40–80%), and superficial (under 40%), and number of adenomyotic foci. Clinical data were collected from patient records. Results: Specimens were categorized in four groups, 17 with adenomyosis alone, 19 with adenomyosis with leiomyomas, 39 with leiomyomas alone, and 36 with neither. Among women with adenomyosis alone, 58.8% had pregnancy terminations and 47.4% of women with adenomyosis and leiomyomas had terminations, compared with 20.5% of women with leiomyomas alone (P < .01) and 22.2% in those with neither (P < .01). The number of foci correlated significantly with depth within the myometrium in specimens with adenomyosis alone (r = .46, P = .05) or combined with leiomyomas (r = .66, P < .001). The median number of foci associated with dysmenorrhea was 10 compared with 4.5 without it (P < .003); in menorrhagia the respective median numbers were 7 and 7 (P = .25). Menorrhagia and dysmenorrhea presented in 36.8% and 77.8% of deep, compared with 13.3% (P < .001) and 12.5% (P < .001) of intermediate depths, respectively. Superficial depth was not associated with menorrhagia or dysmenorrhea. Conclusion: Pregnancy termination might affect the pathogenesis of adenomyosis. The number of foci and their myometrial depths correlated to each other and to dysmenorrhea, but only myometrial depth correlated to menorrhagia.
Stress-related mucosal disease in childhood appendicitis

Stress-related mucosal disease (SRMD) is known to occur in critically ill patients both in the adult and paediatric population. Acute appendicitis is the most common surgical emergency in childhood and can precipitate SRMD. This possibility should be kept in mind, particularly in prolonged, complicated episodes. Although clinical complications of SRMD are rare, they may be highly significant in terms of haemorrhage or perforation and result in considerable morbidity or mortality. We provide a thorough review of the incidence, aetiology, role of Helicobacter pylori, risk factors, prophylaxis and management of this condition and describe a series of three cases of ulcerative SRMD in children with complicated appendicitis.
The Borkenau thesis and the origins of the west

Franz Borkenau died in Vienna in 1957, at the comparatively early age of fifty-six. In 1981, Richard Lowenthal brought out a posthumous collection of his papers, mostly unpublished, which has recently been reissued in a paperback edition. There has been little fanfare surrounding this publication, although a contingent of admirers has been growing, almost an underground Borkenau cult. I am happy to include myself as one of them. This book is one of the great intellectual rediscoveries of our time.
Mashing Out the Middleman or the Development of a Service Rich Market Niche: A Study in the System Integration Industry

ABSTRACT McGruder Technologies, a company that has been built on innovation and creativity, likens itself to the knight in a game of chess. In chess, the knight is the only piece that can jump over other pieces. Unlike other chess pieces, it does not follow a straight line or a diagonal one. Applying the analogy to business, McGruder's CEO asserts that he considers the firm's situation and the potential solutions, and overcomes obstacles to accomplish his goals. Unfortunately, the changing forces throughout the economy in 2004 are putting this analogy to a rugged test. This is the story of McGruder Technologies, a system integration company. As a small-to-midsize company in this rapidly changing environment, McGruder finds itself faced with many challenges. The case identifies McGruder's present position, how it got there, the challenges that it faces, and where it plans to go; finally, the case provides an analysis of McGruder's chosen direction. As in most business situations, only time will tell if McG...
Classroom technology: assisting faculty in finding weapons of mass instruction

Valparaiso University offers 30 classroom technology carts, and in addition, the Valparaiso University School of Law provides five classrooms that are fully technologically equipped including Stride Court Room where "technology in the classroom becomes technology in the courtroom."Valparaiso University provides scheduled training for faculty on the utilization of each piece of equipment on the cart, and it encourages faculty to incorporate these devices in their classroom instruction. With these "Ala Carte" choices, faculty do not have to feel overwhelmed by a control panel that looks as if it could launch "weapons of mass destruction." Instead, they can start by utilizing one piece of equipment until they are comfortable, and then incorporate another piece of technology, until they have the full capabilities to launch all "weapons of mass instruction."Instructional User Support staff members contact and provide individual training to faculty who are scheduled in the "High Tech" classrooms. Written instructions are then given to the faculty member;. In addition, by faculty request, a support person will either attend the first session of class or else schedule a "dry run" of the first session.Faculty also are offered an opportunity to demonstrate their use of classroom technology to their peers at a Technology Fair sponsored by The Teaching Resource Center, Electronic Information Services, and Library staff. In our recent event, Communication Professor Lanie Steinwart presented her experiences and philosophy of classroom technology. In addition, Professor Steinwart stated that students have shorter attention spans, can simultaneously process information, and need instant gratification in regard to their educational needs.
Motor neuronal loss and neurofilament-ubiquitin alteration in MoMuLV-ts1 encephalopathy

A temperature-sensitive mutant of Moloney murine leukemia virus (MoMuLV-ts1) induces immunosuppression and spongiform encephalopathy in susceptible newborn mice. The associated neuronal degeneration primarily involves the motor neurons in specific target areas of the central nervous system (CNS). Neuronal loss occurs in the absence of direct viral infection of neurons and is the most dramatic pathological change in the CNS of infected mice. To quantitatively demonstrate neuronal loss, an unbiased morphometric stereological study was undertaken using the optical disector method. Using highly susceptible FVB/N mice, neuronal loss was quantitated in the tissue sections of brain stem from infected and noninfected mice at 20 and 35 days post inoculation (dpi). Results indicated that there was no significant neuronal loss at 20 dpi, but significant (P < 0.05) at 35 dpi. In addition, histology, transmission electron microscopy and immunohistochemistry revealed Lewy body-like inclusions consisting of aggregates of neurofilaments and cellular organelles. Degenerated neurons and glial cells were heavily ubiquitinated. Together, these results suggest that significant neuronal loss occurs at the end of the disease process and that Lewy body-like formation and protein ubiquitination are part of the pathogenic process in ts1-induced encephalopathy.
Has the mystery of the vanishing 15N in isotope dilution experiments been resolved

This paper comments on a recent paper by Laws regarding the mystery of the vanishing /sup 14/N. The mystery of the missing /sup 15/N lies in the difference between u, the NH/sub 3//sup +/ pool loss term, and P, the rate of microplankton accumulation of label from the NH/sub 4//sup +/ pool, but the biological cause of the discrepancy remains unclear. The authors stated in an earlier paper that a systematic but unidentified error in the data or other losses from the NH/sub 4//sup +/ pool, such as nitrification could be the culprit.
Structures and stabilities of the group IIIa dihydrides

Abstract The CaF2-type dihydrides of the group IIIa elements represent a relatively large family of similar metallic hydrides for which relationships between interatomic distances and stabilities can be derived. Available data for the thermodynamic properties of formation of these dihydrides were assembled and the enthalpies and free energies of formation are compared with the metal-hydrogen distances in the hydrides. The data show that for these hydrides there is a maximum in the stability-distance curve; the most stable dihydrides are HoH2 and DyH2 with metal-hydrogen distances of 2.237A and 2.252 A respectively. A modified Born-Mayer ionic model is applied to this family of dihydrides. In addition to the usual Coulomb (attraction) and overlap (repulsion) terms, an additional attraction term is introduced to take into account residual metallic cohesion in the hydride lattice. The results obtained from this model are compared with the thermochemical data using the BornHaber cycle. In making this comparison a parameter β (which has units of length) is introduced which accounts for the influence of the 4f electronic structure on the repulsive potential for the lanthanide dihydrides. It is shown that the relation between stability and the sum of the metallic radius and the tetrahedral hole radius (in the metal) is similar to that between stability and the actual metal-hydrogen distance in these dihydrides. This similarity is used to rationalize observed correlations between stability and tetrahedral hole sizes in intermetallic compound hydrides.
Latitude and latitudinal extent: a global analysis of the Rapoport effect in a tropical mammalian taxon: primates

Aim Analyses of the Rapoport effect (species at high latitudes have broader latitudinal ranges) usually indicate only a weak effect in the tropics. However, studies of tropical taxa are rare. This study used a global analysis of a tropical order, primates, to ask two questions. Is there a Rapoport effect in this tropical, terrestrial mammal, globally or per continent? If so, can the effect be explained by greater adaptability of higher latitude taxa. Location Globe. Methods Geographical data for the majority of primates species are available. Genera, rather than the species, were the main data used because the genus is a more stable taxonomic level for this order. Regressions and Spearman correlations were used to test for the effect. Generic ranges are the sum of the constituent species’ ranges. In addition, phylogenetic effects were controlled for to minimize dependence of data. Results The Rapoport effect is apparent globally when Madagascar and outlier taxa are excluded. It is also present separately in Africa, Asia and Madagascar when outlier genera are excluded, but not in South America. The effect persists globally, and in Africa and Asia when phylogeny is controlled for. Climatic variation (temperature or precipitation) correlates with either mid-latitude or extent of latitude of genera in Africa, Asia and the Americas (insufficient data for Madagascar), but controlling for phylogeny confirms only the African and Asian correlations. The four measures of adaptability of taxa (number of dietary types, number of habitat types, body mass and number of species per genus) correlated variously with latitudinal extent of the taxa, but the correlations did not always match the existence of a Rapoport effect in the respective continents. Main conclusions The intercontinental variation apparent in the Rapoport effect in the tropics should be fruitful material for further study of the causes of the Rapoport effect. The discovery of significant associations of measures of adaptability with latitudinal extent in both the presence and the absence of a Rapoport effect indicates that care is needed in using such associations to explain the Rapoport effect.

The product-product singular value decomposition of matrix triplets

A new decomposition of a matrix triplet (A, B, C) corresponding to the singular value decomposition of the matrix productABC is developed in this paper, which will be termed theProduct-Product Singular Value Decomposition (PPSVD). An orthogonal variant of the decomposition which is more suitable for the purpose of numerical computation is also proposed. Some geometric and algebraic issues of the PPSVD, such as the variational and geometric interpretations, and uniqueness properties are discussed. A numerical algorithm for stably computing the PPSVD is given based on the implicit Kogbetliantz technique. A numerical example is outlined to demonstrate the accuracy of the proposed algorithm.
Electoral Reform and the Fate of Factions: The Case of Japan's Liberal Democratic Party

For years, scholars and pundits have blamed Japan's single, non-transferable vote (SNTV) electoral system for the factions that divide and organize the ruling Liberal Democratic Party (LDP). In January 1994, Japan abandoned SNTV, and the first election under the new rules occurred in October 1996. If SNTV did in fact sustain the factions, it makes sense that the factional structure ought to have weakened under the new rules. In this article, we provide an informal model of what the old factional exchange between leaders and followers was like and investigate the extent to which the terms of this exchange, and hence the characteristics of Japanese factionalism, have begun to change under the new rules. We expect and find the largest decline in factional leaders' role in the area of nominations, and the slightest changes, at least in the short run, in the allocation of posts. On the other side of the exchange, we find that followers appear less willing to march to their leaders' tunes in LDP presidential elections.
Formation of ultracold polar molecules via Raman excitation

Alkali hydride molecules are very polar, exhibiting large ground-state dipole moments. As ultracold sources of alkali atoms, as well as hydrogen, have been created in the laboratory, we explore theoretically the feasibility of forming such molecules from a mixture of the ultracold atomic gases, employing a two-photon stimulated radiative association process -- Raman excitation. Using accurate molecular potential energy curves and dipole transition moments, we have calculated the rate coefficients for populating all the vibrational levels of the X $^1{\rm\Sigma}^ + $ state of LiH via the excited A $^1{\rm\Sigma}^ + $ state. We have found that significant molecule formation rates can be realized with laser intensities and atomic densities that are attainable experimentally. Because of the large X state dipole moment, rapid cascade occurs down the ladder of vibrational levels to v = 0. The calculated recoil momentum imparted to the molecule is small, and thus negligible trap loss results from the cascade process. This allows for the build-up of a large population of v = 0 trapped molecules.
Laser Transmission Welding of Thermoplastics—Part II: Experimental Model Validation

Two laser transmission welding experiments involving polyvinyl chloride are presented that aim to validate a previously presented welding model while helping to further understand the relationship between welding parameters and weld quality. While numerous previous research papers have presented the results of laser welding experiments, there exists minimal work validating models of the welding process. The first experiment explores the interaction of laser power and welding velocity while the second experiment explores the influence of clamping pressure. Using the weld width as the primary model output, the agreement between the welding experiments and the model have an average error of 5.6%. This finding strongly supports the validity of the model presented in Part I of this two paper set (Van de Ven and Erdman, 2007, ASME J. Manuf. Sci. Eng., 129, pp. 849-858). Additional information was gained regarding the operating window for laser transmission welding and the thermal decomposition of polyvinyl chloride. Clamping pressure was found to provide a small, but not statistically significant, influence on the visual appearance, weld width, and weld strength.
Invasive cervical adenocarcinoma immediately following a cone biopsy for adenocarcinoma in situ with negative margins

Abstract Background. Cervical adenocarcinoma in situ is often diagnosed in younger women who may wish to preserve the potential for fertility. Given that the rate of recurrent adenocarcinoma in situ is relatively low and the risk of invasive adenocarcinoma is extremely rare, conservative management in this population after a cone biopsy demonstrates negative margins has been accepted as an appropriate management strategy. This case challenges the concept of conservative management of cervical adenocarcinoma in situ. Case. A 42-year-old G2P2002 with previously normal annual cervical cytology had a Pap smear demonstrating atypical glandular cells of uncertain significance. A 1.5-cm lesion was noted at the endocervix, and a punch biopsy revealed adenocarcinoma in situ. A large cold knife cone biopsy confirmed cervical adenocarcinoma in situ with negative margins. Definitive therapy for in situ disease with an extrafascial hysterectomy was performed 12 days after conization, and demonstrated stage IB1 cervical adenocarcinoma. A radical parametrectomy, radical upper vaginectomy, and pelvic lymphadenectomy were without persistent disease. Conclusion. Conservative management of cervical adenocarcinoma in situ after a cone biopsy with negative margins does not exclude the possibility of concurrent invasive cervical adenocarcinoma. This case challenges the current balance between risk and benefit associated with the conservative management of cervical adenocarcinoma in situ.
Correlation between neuroleptic binding to σ1 and σ2 receptors and acute dystonic reactions

Acute dystonic reactions are motor side effects that occur soon after the initiation of neuroleptic treatment. Although earlier studies indicate that these abnormal movements can be induced in animals and humans via activation of sigma receptors, the relative contribution of the different sigma receptor subtypes is unknown. Since sigma(1) and sigma(2) receptor are differentially represented in motor regions of the brain, the affinities of 17 neuroleptics for these sigma receptor subtypes were determined using competition binding studies. The results revealed that most neuroleptics do not exhibit selectivity for either of the sigma receptor subtypes, as reflected by a significant correlation between the affinities of the neuroleptics for sigma(1) vs. sigma(2) receptors. Moreover, when the sigma binding affinities of the neuroleptics were correlated with the tendency of the drugs to produce acute dystonic reactions in humans, there was a significant correlation for both subtypes. Together with earlier studies in animals, the data suggest that neuroleptic-induced motor side effects can be mediated through both sigma(1) and sigma(2) receptors.
Paradigmatic versus Historical Thinking: The Case of Rabbinic Judaism

The idea of history, with its rigid distinction between past and present and its careful sifting of connections from the one to the other, came quite late onto the scene of intellectual life. Both Judaism and Christianity for most of their histories have read the Hebrew Scriptures from within an other-than-historical framework. They found in Scripture's words paradigms of an enduring present, by which all things must take their measure; they possessed no conception whatsoever of the pastness of the past. Rabbinic Judaism invented an entirely new way to think about times past and to keep all time—past, present, and future—within a single framework. For that purpose, a model was constructed, consisting of selected events held to form a pattern that imposes order and meaning on the chaos of what happens, whether past or present or future. Time measured in the paradigmatic manner is time formulated by a free-standing, (incidentally) atemporal model, not appealing to the course of sun and moon, nor concerned with the metaphor of human life and its cyclicality. Not only so, but the paradigm obliterates distinctions between past, present, and future, between here and now and then and there. The past participates in the present, the present recapitulates the past, and the future finds itself determined, predetermined really, within the same free-standing structure comprised by God's way of telling time.
Sampling strategies for subsampled segmented EPI PRF thermometry in MR guided high intensity focused ultrasound

Purpose: To investigate k-space subsampling strategies to achieve fast, large field-of-view (FOV) temperature monitoring using segmented echo planar imaging (EPI) proton resonance frequency shift thermometry for MR guided high intensity focused ultrasound (MRgHIFU) applications. Methods: Five different k-space sampling approaches were investigated, varying sample spacing (equally vs nonequally spaced within the echo train), sampling density (variable sampling density in zero, one, and two dimensions), and utilizing sequential or centric sampling. Three of the schemes utilized sequential sampling with the sampling density varied in zero, one, and two dimensions, to investigate sampling the k-space center more frequently. Two of the schemes utilized centric sampling to acquire the k-space center with a longer echo time for improved phase measurements, and vary the sampling density in zero and two dimensions, respectively. Phantom experiments and a theoretical point spread function analysis were performed to investigate their performance. Variable density sampling in zero and two dimensions was also implemented in a non-EPI GRE pulse sequence for comparison. All subsampled data were reconstructed with a previously described temporally constrained reconstruction (TCR) algorithm. Results: The accuracy of each sampling strategy in measuring the temperature rise in the HIFU focal spot was measured in terms of the root-mean-square-errormore » (RMSE) compared to fully sampled “truth.” For the schemes utilizing sequential sampling, the accuracy was found to improve with the dimensionality of the variable density sampling, giving values of 0.65 °C, 0.49 °C, and 0.35 °C for density variation in zero, one, and two dimensions, respectively. The schemes utilizing centric sampling were found to underestimate the temperature rise, with RMSE values of 1.05 °C and 1.31 °C, for variable density sampling in zero and two dimensions, respectively. Similar subsampling schemes with variable density sampling implemented in zero and two dimensions in a non-EPI GRE pulse sequence both resulted in accurate temperature measurements (RMSE of 0.70 °C and 0.63 °C, respectively). With sequential sampling in the described EPI implementation, temperature monitoring over a 192 × 144 × 135 mm{sup 3} FOV with a temporal resolution of 3.6 s was achieved, while keeping the RMSE compared to fully sampled “truth” below 0.35 °C. Conclusions: When segmented EPI readouts are used in conjunction with k-space subsampling for MR thermometry applications, sampling schemes with sequential sampling, with or without variable density sampling, obtain accurate phase and temperature measurements when using a TCR reconstruction algorithm. Improved temperature measurement accuracy can be achieved with variable density sampling. Centric sampling leads to phase bias, resulting in temperature underestimations.« less
The enthalpy of dilution and apparent molar heat capacity of NaOH(aq) to 523 K and 40 MPa

Abstract The molar enthalpy of dilution Δ dil H m of NaOH(aq) was measured from 6.3 to 0.008 mol · kg −1 at temperatures from 298 to 523 K and pressures from 7 to 40 MPa with a differential flow mixing enthalpy calorimeter. Apparent molar heat capacities C p , φ were measured with a flow heat-capacity calorimeter from 4.0 to 0.1 mol · kg −1 from 323 to 523 K at 7 MPa. These results are correlated with available literature values as functions of temperature, pressure, and molality with the ion-interaction thermodynamic treatment. The extended form of the ion-interaction model, including an approximation for the effect of ion association, was needed to represent the enthalpy results quantitatively above 473.15 K; this additional term does not have a large effect on the activity or osmotic coefficients. Standard heat capacities calculated from this work are consistent with literature values for the heat-capacity change on ionization of water.
Wavelength selection for color holography

Color holography is typically achieved through the use of three wavelengths during the imaging. However, three-color holography is sufficient only when one has the freedom to select locally the proportions of the primaries during reconstruction. This freedom exists in some, but not all, holographic techniques; we discuss wavelength selection in light of this distinction. For holograms that do not allow for local control of color, such as display holography, the color contributions depend on the surface reflectances in the scene; the monochromatic sources point sample these reflectances. From this sampling, we show that the problem of wavelength selection is equivalent to that of finding efficient approximations to the tristimulus integrals. We conclude that three sources are often insufficient for accurate color reproduction, and we suggest wavelengths for holography with three, four, or more wavelengths. For holograms that do allow for local color control, the color science involved is similar to that of raster displays. Therefore, only three primaries are necessary. However, we describe situations where only two primaries are sufficient. This conclusion follows from the dichromatic theory of color reflection, which postulates that often the reflection of light from a surface contains only two color components.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

RESEARCH: Sanctification of Parenting: Links to Corporal Punishment and Parental Warmth Among Biblically Conservative and Liberal Mothers

A growing body of research has examined links between religious beliefs and parenting practices. This study used the theoretical construct of sanctification to examine the degree to which parenting holds spiritual significance and meaning for parents and whether sanctification is related to parenting behaviors. Seventy—four mothers completed questionnaires measuring sanctification of the parenting role, a biblical conservatism scale, and measures of parenting practices. Greater sanctification of parenting was associated with less use of verbal aggression and, to some extent, increased parental consistency. Biblical conservatism moderated the link between sanctification and (a) use of corporal punishment and (b) positive parent—child interactions. Specifically, greater sanctification of parenting was tied to decreased corporal punishment by mothers with liberal biblical beliefs but related to more use of corporal punishment among conservative mothers; greater sanctification was tied to increased positive m...
Characterization of a principle resembling oxytocin in the pituitary of the holocephalian ratfish (Hydrolagus colliei) by partition chromatography on Sephadex columns.

Abstract An oxytocic fraction has been isolated from pituitaries of the ratfish ( Hydrolagus colliei ) with pharmacological properties that differ from those of all known naturally occurring neurohypophysial principles except oxytocin. When subjected to partition column chromatography on Sephadex the Hydrolagus fraction appears to be a single peptide. Its mobilities on such columns are the same as those of oxytocin. If this principle is oxytocin its presence in the ratfish raises new questions concerning the manner in which neurohypophysial peptides have changed during the course of vertebrate evolution.
Single cell analysis shows decreasing FoxP3 and TGFβ1 coexpressing CD4+CD25+ regulatory T cells during autoimmune diabetes

Natural CD4+CD25+ regulatory T (CD4+CD25+ T reg) cells play a key role in the immunoregulation of autoimmunity. However, little is known about the interactions between CD4+CD25+ T reg cells and autoreactive T cells. This is due, in part, to the difficulty of using cell surface markers to identify CD4+CD25+ T reg cells accurately. Using a novel real-time PCR assay, mRNA copy number of FoxP3, TGFβ1, and interleukin (IL)-10 was measured in single cells to characterize and quantify CD4+CD25+ T reg cells in the nonobese diabetic (NOD) mouse, a murine model for type 1 diabetes (T1D). The suppressor function of CD4+CD25+CD62Lhi T cells, mediated by TGFβ, declined in an age-dependent manner. This loss of function coincided with a temporal decrease in the percentage of FoxP3 and TGFβ1 coexpressing T cells within pancreatic lymph node and islet infiltrating CD4+CD25+CD62Lhi T cells, and was detected in female NOD mice but not in NOD male mice, or NOR or C57BL/6 female mice. These results demonstrate that the majority of FoxP3-positive CD4+CD25+ T reg cells in NOD mice express TGFβ1 but not IL-10, and that a defect in the maintenance and/or expansion of this pool of immunoregulatory effectors is associated with the progression of T1D.
