Intrapersonal correlates of aggression in adolescents: determinants of undertaking the role of the perpetrator and the victim
Authors: Farnicka Marzanna , Grzegorzewska Iwona
Published: June 2015

Background

Youthful aggression, perceived both as a social phenomenon and a psychological issue, is the subject matter of numerous theoretical analyses and scientific studies. Usually, their aim is to determine the consequences of aggressive behaviour, especially the development of criminal behaviour. However, empirical studies devoted to the relations between aggressive behaviour of Polish youth and intrapersonal factors are still lacking. The main aim of the research presented in this paper was to determine the relationship between attachment, temperament, aggressiveness and aggressive behaviour among young people. For research purposes, the multidimensional aggression model developed by Anderson and Bushman was used.

Participants and procedure

Measurements were carried out with the Buss-Perry Aggressiveness Scale, the Parent and Peer Attachment Inventory by Armsden and Greenberg, the Buss and Plomin Temperament Scale and the Mini DIA Questionnaire (Österman and Björqvist). The studied group consisted of 120 young persons aged between 16 and 19.

Results

The research results support the conclusion that the dominant temperamental component of persons characterized by a high level of aggressiveness is anger. Also, correlations were found indicating that a high level of trust and a high level of alienation in the relationship with the mother are connected with anger as an aggressiveness component.

Conclusions

The actually undertaken aggressive behaviour depends on the prevailing aggressiveness dimension: the frequency of perpetrator-type behaviour increases along with the general aggressiveness level and the frequency of its manifestation in the form of physical and verbal aggression, while the frequency of victim-type behaviour increases along with the experienced level of anger and hostility.

Published: June 2015

The progression of heart failure (HF), similarly to other chronic and/or terminal diseases, affects the psychological status of the patients, with consequences for general well-being. The changes in psychological features can be measured and quantified using numerous psychological questionnaires, which do not establish any diagnosis of pathology, although they may be important for the effectiveness of applied treatment of patients with HF. In this paper, we summarize and discuss available evidence on psychological phenomena occurring in the course of HF, such as: ‘Type D’ personality, anxiety, psychological distress, coping strategies, sense of coherence, affectivity, sense of self-efficacy, sense of control and health perception, along with the presentation of available and validated measures of psychological features.
Raising children bilingually
Authors: Langdon Henriette W.
Published: June 2015

The purpose of this article is to describe the process of becoming bilingual by sharing my own experience being raised in a four-language environment and how it influenced the upbringing of my daughter in two, and subsequently three languages. The other purpose is to dispel the myth that children with language, developmental and/or intellectual impairments or those diagnosed as being on the autism spectrum cannot or should not be exposed to two languages because it is confusing, or because they simply cannot handle two languages due to their disability. As a bilingual speech and language pathologist (SLP) who has practiced in the United States for four decades, I have unfortunately witnessed that many teachers as well as other well-meaning professionals including psychologists, therapists and even physicians discourage these children’s parents from using their first language because it might be confusing or too difficult for the child to handle. A review of recent research on children with special needs who have a variety of language, learning and communication challenges contradicts this view. The information presented should be helpful not only to parents but also to various professionals including therapists and physicians who come into contact with children with special needs who are growing up in a bilingual environment.

Published: June 2015

Objectives: Protective vaccinations are the most effective method of prevention of type B virus hepatitis. The aim of the study was to determine whether in children receiving immunosuppressive therapy due to inflammatory systemic connective tissue diseases the protective concentration of the anti-HBs antibodies produced after vaccination against type B virus hepatitis in infancy is maintained.

Material and methods: The concentration of anti-HBs antibodies was assessed in the sera of 50 children with inflammatory connective tissue diseases – 37 girls (74%) and 13 boys (26%), aged 1.5–17.5 years – during the immunosuppressive treatment, which lasted at least 6 months. The control group consisted of 50 healthy children – 28 girls (56%) and 22 boys (44%) aged 2–17 years. All children were vaccinated in infancy with Engerix B vaccine according to the 0–1–6 months schedule. The antibody concentration of ≥ 10 mIU/ml in patients is regarded as protective.

Results:  No protective antibody concentrations were found in 25 cases (50%) in the group of diseased children and only in 2 children in the control group (4%).

Conclusions: The concentration of vaccine-induced antibodies should be assessed in children with inflammatory systemic connective tissue diseases and, in case of the absence of a protective concentration, revaccination should be started. The use of glucocorticosteroids, synthetic and biological disease-modifying antirheumatic drugs is no contraindication to vaccination against hepatitis B.
Adult-onset Still’s disease as a mask of Hodgkin lymphoma
Authors: Dudziec Ewa , Pawlak-Buś Katarzyna , Leszczyński Piotr
Published: June 2015

Adult-onset Still’s disease is a rare disorder, which creates difficulties in making a proper diagnosis. Ambiguous symptoms and results of auxiliary tests, lack of unequivocal diagnostic tests and the need to exclude other causes of the disease are major problems in clinical practice.

A case of a 22-year-old woman with dominated recurrent fever, significantly elevated inflammation markers and arthritis is presented. Based on clinical signs after exclusion of infection, hematological and other reasons, the patient was diagnosed with adult-onset Still’s disease. Standard treatment, with high doses of glucocorticoids and a disease-modifying drug, was applied, without the anticipated effects. The diagnostic tests were conducted again due to the lack of clinical improvement, increase of inflammatory markers and unusual response to treatment. A new symptom of significance, i.e. mediastinal lymphadenopathy, was found. After the histopathological examination of lymph nodes, Hodgkin’s disease was diagnosed and targeted therapy for hematological malignancy was applied.

The 11-year solar cycle in current reanalyses: a (non)linear attribution study of the middle atmosphere
Authors: Kuchar A. , Sacha P. , Miksovsky J. , Pisoft P.
Published: June 2015

Abstract. This study focusses on the variability of temperature, ozone and circulation characteristics in the stratosphere and lower mesosphere with regard to the influence of the 11-year solar cycle. It is based on attribution analysis using multiple nonlinear techniques (support vector regression, neural networks) besides the multiple linear regression approach. The analysis was applied to several current reanalysis data sets for the 1979–2013 period, including MERRA, ERA-Interim and JRA-55, with the aim to compare how these types of data resolve especially the double-peaked solar response in temperature and ozone variables and the consequent changes induced by these anomalies. Equatorial temperature signals in the tropical stratosphere were found to be in qualitative agreement with previous attribution studies, although the agreement with observational results was incomplete, especially for JRA-55. The analysis also pointed to the solar signal in the ozone data sets (i.e. MERRA and ERA-Interim) not being consistent with the observed double-peaked ozone anomaly extracted from satellite measurements. The results obtained by linear regression were confirmed by the nonlinear approach through all data sets, suggesting that linear regression is a relevant tool to sufficiently resolve the solar signal in the middle atmosphere. The seasonal evolution of the solar response was also discussed in terms of dynamical causalities in the winter hemispheres. The hypothetical mechanism of a weaker Brewer–Dobson circulation at solar maxima was reviewed together with a discussion of polar vortex behaviour.
Spatial and temporal variability of clouds and precipitation over Germany: multiscale simulations across the "gray zone"
Authors: Barthlott C. , Hoose C.
Published: June 2015

Abstract. This paper assesses the resolution dependance of clouds and precipitation over Germany by numerical simulations with the COnsortium for Small-scale MOdeling (COSMO) model. Six intensive observation periods of the HOPE (HD(CP)2 Observational Prototype Experiment) measurement campaign conducted in spring 2013 and one summer day of the same year are simulated. By means of a series of grid-refinement resolution tests (horizontal grid spacing 2.8, 1 km, 500 and 250 m), the applicability of the COSMO model to real weather events in the terra incognita, i. e. the scale ranging between the mesoscale limit (no turbulence resolved) and the large-eddy simulation limit (energy-containing turbulence resolved), is tested. It is found that although the representation of a number of processes is enhanced with resolution (e. g. boundary-layer thermals, low-level convergence zones, gravity waves), their influence on the temporal evolution of precipitation is rather weak. However, rain intensities may vary with resolution, leading to differences in the total rain amount of up to +48 %. Furthermore, the location of rain is similar for the springtime cases with moderate and strong synoptic forcing, whereas significant differences are obtained for the summertime case with air mass convection. Probability density functions of convection-related parameters are analyzed to investigate their dependance on model resolution and their impact on cloud formation and subsequent precipitation.
Estimating ground-level PM2.5 in Eastern China using aerosol optical depth determined from the GOCI Satellite Instrument

Abstract. We determine and interpret fine particulate matter (PM2.5) concentrations in East China for January to December 2013 at a horizontal resolution of 6 km from aerosol optical depth (AOD) retrieved from the Korean Geostationary Ocean Color Imager (GOCI) satellite instrument. We implement a set of filters to minimize cloud contamination in GOCI AOD. Evaluation of filtered GOCI AOD with AOD from the Aerosol Robotic Network (AERONET) indicates significant agreement with mean fractional bias (MFB) in Beijing of 6.7 % and northern Taiwan of −1.2 %. We use a global chemical transport model (GEOS-Chem) to relate the total column AOD to the near-surface PM2.5. The simulated PM2.5/AOD ratio exhibits high consistency with ground-based measurements (MFB = −0.52–8.0 %). We evaluate the satellite-derived PM2.5 vs. the ground-level PM2.5 in 2013 measured by the China Environmental Monitoring Center. Significant agreement is found between GOCI-derived PM2.5 and in-situ observations in both annual averages (r = 0.81, N = 494) and monthly averages (MFB = 13.1 %), indicating GOCI provides valuable data for air quality studies in Northeast Asia. The GEOS-Chem simulated chemical speciation of GOCI-derived PM2.5 reveals that secondary inorganics (SO42−, NO3−, NH4+) and organic matter are the most significant components. Biofuel emissions in northern China for heating are responsible for an increase in the concentration of organic matter in winter. The population-weighted GOCI-derived PM2.5 over East China for 2013 is 53.8 μg m−3, threatening the health and life expectancy of its 600 million residents.
Technical Note: Cost-efficient approaches to measure carbon dioxide (CO2) fluxes and concentrations in terrestrial and aquatic environments using mini loggers
Authors: Bastviken D. , Sundgren I. , Natchimuthu S. , Reyier H. , Gålfalk M.
Published: June 2015

Abstract. Fluxes of CO2 are important for our understanding of the global carbon cycle and greenhouse gas balances. Several significant CO2 fluxes in nature may still be unknown as illustrated by recent findings of high CO2 emissions from aquatic environments, previously not recognized in global carbon balances. Therefore, it is important to develop convenient and affordable ways to measure CO2 in many types of environments. At present, direct measurements of CO2 fluxes from soil or water, or CO2 concentrations in surface water, are typically labor intensive or require costly equipment. We here present an approach with measurement units based on small inexpensive CO2 loggers, originally made for indoor air quality monitoring, that were tested and adapted for field use. Measurements of soil–atmosphere and lake–atmosphere fluxes, as well as of spatiotemporal dynamics of water CO2 concentrations (expressed as the equivalent partial pressure, pCO2aq) in lakes and a stream network are provided as examples. Results from all these examples indicate that this approach can provide a cost- and labor-efficient alternative for direct measurements and monitoring of CO2 flux and pCO2aq in terrestrial and aquatic environments.
On studying relations between time series in climatology
Authors: Privalsky V.
Published: June 2015

Abstract. Relationships between time series are often studied on the basis of cross-correlation coefficients and regression equations. This approach is generally incorrect for time series, irrespective of the cross-correlation coefficient value, because relations between time series are frequency-dependent. Multivariate time series should be analyzed in both time and frequency domains, including fitting a parametric (preferably, autoregressive) stochastic difference equation to the time series and then calculating functions of frequency such as spectra and coherent spectra, coherences, and frequency response functions. The example with a bivariate time series "Atlantic Multidecadal Oscillation (AMO) – sea surface temperature in Niño area 3.4 (SST3.4)" proves that even when the cross correlation is low, the time series' components can be closely related to each other. A full time and frequency domain description of this bivariate time series is given. The AMO–SST3.4 time series is shown to form a closed-feedback loop system with a 2-year memory. The coherence between AMO and SST3.4 is statistically significant at intermediate frequencies where the coherent spectra amount up to 55 % of the total spectral densities. The gain factors are also described. Some recommendations are offered regarding time series analysis in climatology.
Changes in the timing and duration of the near-surface soil freeze/thaw status from 1956 to 2006 across China
Authors: Wang K. , Zhang T. , Zhong X.
Published: June 2015

Abstract. The near-surface soil freeze/thaw status is an important indicator of climate change. Using data from 636 meteorological stations across China, we investigated the changes in the first date, the last date, the duration, and the number of days of the near-surface soil freeze over the period 1956–2006. The results reveal that the first date of the near-surface soil freeze was delayed by about 5 days, or at a rate of 0.10 ± 0.03 day yr−1, and the last date was advanced by about 7 days, or at a rate of 0.15 ± 0.02 day yr−1. The duration of the near-surface soil freeze decreased by about 12 days or at a rate of 0.25 ± 0.04 day yr−1, while the actual number of the near-surface soil freeze days decreased by about 10 days or at a rate of 0.20 ± 0.03 day yr−1. The rates of changes in the near-surface soil freeze/thaw status increased dramatically from the early 1990s through the end of the study period. Regionally, the changes in western China were greater than those in eastern China. Changes in the near-surface soil freeze/thaw status were primarily controlled by changes in air temperature, but urbanization may also play an important role.
Comparison of a coupled snow thermodynamic and radiative transfer model with in-situ active microwave signatures of snow-covered smooth first-year sea ice
Authors: Fuller M. C. , Geldsetzer T. , Yackel J. , Gill J. P. S.
Published: June 2015

Abstract. Within the context of developing data inversion and assimilation techniques for C-band backscatter over sea ice, snow physical models may be used to drive backscatter models for comparison and optimization with satellite observations. Such modeling has potential to enhance understanding of snow on sea ice properties required for unambiguous interpretation of active microwave imagery. An end-to-end modeling suite is introduced, incorporating regional reanalysis data (NARR), a snow model (SNTHERM), and a multi-layer snow and ice active microwave backscatter model (MSIB). This modeling suite is assessed against measured snow on sea ice geophysical properties, and against measured active microwave backscatter. NARR data was input to the SNTHERM snow thermodynamic model, in order to drive the MISB model for comparison to detailed geophysical measurements and surface-based observations of C-band backscatter of snow on first-year sea ice. The NARR data was well correlated to available in-situ measurements, with the exception of long wave incoming radiation and relative humidity, which impacted SNTHERM simulations of snow temperature. SNTHERM reasonably represented snow grain size and density when compared to observations. The application of in-situ salinity profiles to one SNTHERM snow profile resulted in simulated backscatter close to that driven by in-situ snow properties. In other test cases, the simulated backscatter remained 4 to 6 dB below observed for higher incidence angles, and when compared to an average simulated backscatter of in-situ end-member snowcovers. Development of C-band inversion and assimilation schemes employing SNTHERM89.rev4 should consider sensitivity of the model to bias in incoming longwave radiation, the effects of brine, and the inability of SNTHERM89.Rev4 to simulate water accumulation and refreezing at the bottom and mid-layers of the snowpack with regard to thermodynamic response, brine wicking and volume processes, snow dielectrics, and microwave backscatter from snow on first-year sea-ice.

Meelzaak – beperking aansprakelijkheid investeringsmaatschappijen door ACM?

In deze bijdrage wordt ingegaan op de ACM-besluiten inzake Bencis en CVC van 30 november 2014. Met deze besluiten heeft ACM, in navolging van de praktijk van de Europese Commissie, voor het eerst investeringsmaatschappijen beboet voor een inbreuk begaan door een dochtervennootschap. In eerste instantie is alleen de dochtervennootschap, Meneba, aansprakelijk gehouden voor een gestelde kartelinbreuk. In twee nieuwe besluiten zijn Bencis en CVC, beide investeerders, alsnog beboet als gevolg van de inbreuk begaan door hun dochtervennootschap Meneba. De besluiten roepen een aantal interessante vragen op, waaronder met betrekking tot (1) de – in lijn met Europese jurisprudentie – lage standaard die ACM toepast voor toerekening van de inbreuk aan moedervennootschappen, in lijn met recente Europese jurisprudentie; (2) het nemen van een nieuw besluit ten aanzien van de moedervennootschappen; en (3) de wijze van omzetberekening voor de boete.

Juvenile delinquency in comparative perspective: do micro and macro analyses tell the same story?

This article presents a micro- and a macro-level analysis of predictors of delinquency in order to contribute to the discussion about the micro-macro problem in criminology. We use Coleman’s boat (1990) to situate our research question. Individual theories dominate the field of delinquency, there are few theories at macro level. Cross-level theoretical integration primarily takes place between individual (micro) and community (meso) levels, and hardly ever on (national) macro level. Our question is to which extent macro-level theory fruitfully may use concepts drawn from micro-level theory. We test a micro and a macro model using indicators from the domains of family, school, friends/peers and economy, using data collected by the Second International Self-Report Study of Delinquency (ISRD2), a cross-national self-report survey of delinquency and victimization among students between 12 and 16 years in 30 countries (n=71.436). Dependent variable at micro level is versatility (last year), at the macro level (national) we use contacts with the police for youths under 18. Results confirm the importance of including macro context (country clusters) in the analysis of individual delinquency. We further conclude that factors related to family and friends correlate at both micro and macro level with measures of delinquency; the role of school and economic factors is less clear-cut. The article concludes with the recommendation to give the micro-macro problem in delinquency theory a more central and explicit position in research programs.

A review on developments of the Internet and cybercrime and consequences for the international fight against digital child abuse

The explosive growth of the Internet has led to countless new possibilities, and it opened the way for societal progress and an extensive globalization and digitization. However, the original ambition of the Internet as a free, open and neutral medium has also led to new possibilities in the field of crime. The current paper illustrates how governments dealt with the development of the Internet and it gives an explanation for why and how unintended side effects have manifested in society. Using the phenomenon of digital child abuse, this paper offers recommendations for an effective government response and for an effective detection of and fight against cybercrime.

From secularization to securitization: considering the relation between religion, crime and security

The Western world seems to be a secular one. Although secularization has long roots, from the sixties onwards the role of religion in public life has diminished. How did that affect the crime and security issue? Criminological literature learns that there is a two-sided relationship: (1) in a religious context there is an inhibiting effect of being religious; and (2) religion can also legitimize or neutralize criminal or violent behavior – for example in the case of Islam-related terrorist acts. Secularization did indeed contribute to the rise of crime; in nowadays secular context religion can – the other way around – legitimize criminal behavior. The author argues that secularization also has facilitated the growth of the security issue as such. Fear of crime was the driving force behind a process in which secularization resulted in securitization of Western society.

These two words, “Free WIFIA,” were the theme of the 2015 AWWA Fly‐In in Washington, D.C., on March 18 and 19. The Water Matters!® Fly‐In has been an annual event since ACE in 2001. The first Water Matters! rally was held on the steps of the Capitol. Based on the positive response from AWWA members in 2001, that initial event has evolved into an annual event. Hosted by AWWA's Water Utility Council, the Fly‐In has greatly increased the credibility and the leverage of the drinking water community with Congress. About 48 states are consistently represented at the Fly‐In, and the attendees visit the majority of the members of Congress. Hearing from their own voters better motivates the members of Congress to take action and understand AWWA's infrastructure issues.
Potable Reuse Water and Pricing: What Does the Future Hold?
Authors: Kostiuk Kevin , Pardiwala Sudhir , Wright John
Published: June 2015

For water agencies in many parts of the United States, the need to secure reliable sources of water supplies has never been more pressing. Forecast population growth, concerns about the long‐term impact of climate change, and, of course, severe drought conditions in the southwestern and south central United States have made the acquisition and development of new water supplies a critical priority. Agencies are on the lookout for alternative water sources, and cost of water in the spot market has increased significantly. The cost of long‐term sources of potable water supply has also increased. Many water utilities are turning to nontraditional sources of supply such as large‐scale desalination and indirect or direct potable water reuse projects that were once rejected as being too expensive or controversial.
Interactions between Health Care Personnel and Parents Approached for Organ and/or Tissue Donation: Influences on Parents' Adjustment to Loss
Authors: Ashkenazi Tamar , Cohen Jonathan
Published: June 2015

Context—

The effect of loss on those approached for organ and/or tissue donation, particularly in the years thereafter, has received little attention.

Objective—

To assess whether adjustment of a parent to loss of a child is influenced by interactions with health care personnel.

Methods—

A self-administered questionnaire was completed by the parents of 216 decedents. Interactions in the hospital were assessed by examining the experience in the hospital, physical separation from the child, and the relationship with health care professionals. Adjustment to loss was defined by 4 components: grief, personal growth after loss, meaning of life after loss, and the meaning of organ donation.

Results—

A positive experience in the hospital was significantly associated with the meaning of donation. Increased satisfaction with the separation process was associated with better adjustment on all components. Finally, a better relationship with health care professionals was associated with less grief and with greater personal growth. These results were characterized after adjustment for time since loss, which was from 6 months to 27 years.

Conclusions—

Interactions in the hospital appear to influence adjustment to loss significantly. Appropriate interventions may aid parents in their adjustment to life.

Published: June 2015

The rate of living kidney donation from 2006 to 2012 was roughly the same in Australia and New Zealand, but the rate of Good Samaritan donation was significantly higher in New Zealand (1.49 donors/million) than in Australia (0.23 donors/million). Three possible reasons for New Zealand's high rate of Good Samaritan donation are explored: (1) since 2005, New Zealand has offered a tax-free financial safety net for living donors; (2) unlike Australia, New Zealand is not carved into jurisdictional segments with multiple policies on Good Samaritan donation, lending to a streamlined approach; (3) New Zealand embraces e-technology to communicate the concept of Good Samaritan donation to the public. Additionally, New Zealand's recent initiatives to increase the rate of living donation are described.

Dominant role of eddies and filaments in the offshore transport of carbon and nutrients in the California Current System
Authors: Nagai Takeyoshi , Gruber Nicolas , Frenzel Hartmut , Lachkar Zouhair , McWilliams James C. , Plattner Gian‐Kasper
Published: June 2015

The coastal upwelling region of the California Current System (CalCS) is a well‐known site of high productivity and lateral export of nutrients and organic matter, yet neither the magnitude nor the governing processes of this offshore transport are well quantified. Here we address this gap using a high‐resolution (5 km) coupled physical‐biogeochemical numerical simulation (ROMS). The results reveal (i) that the offshore transport is a very substantial component of any material budget in this region, (ii) that it reaches more than 800 km into the offshore domain, and (iii) that this transport is largely controlled by mesoscale processes, involving filaments and westward propagating eddies. The process starts in the nearshore areas, where nutrient and organic matter‐rich upwelled waters pushed offshore by Ekman transport are subducted at the sharp lateral density gradients of upwelling fronts and filaments located at ∼25–100 km from the coast. The filaments are very effective in transporting the subducted material further offshore until they form eddies at their tips at about 100–200 km from the shore. The cyclonic eddies tend to trap the cold, nutrient, and organic matter‐rich waters of the filaments, whereas the anticyclones formed nearby encapsulate the low nutrient and low organic matter waters around the filament. After their detachment, both types of eddies propagate further in offshore direction, with a speed similar to that of the first baroclinic mode Rossby waves, providing the key mechanism for long‐range transport of nitrate and organic matter from the coast deep into the offshore environment.

In this manuscript, highly UV‐sensitive OPTs are fabricated based on benzo[1,2‐b:4,5‐b′]dithiophene dimers (BBDT, BBDTE, and BBDTY). The BBDTE‐based organic single‐crystal transistors (OSCTs), which show carrier mobility up to 1.62 cm2 V−1 s−1, exhibit a maximum photoresponsivity up to 9821 A W−1 and a maximum photosensitivity up to 105 towards UV light (37 μW cm−2), and the photosensitivity observed within tested light intensity range is unexpectedly stable. The BBDTY‐based OPTs also exhibit differentiated response between UV and visible lights, even with thin‐film state of organic semiconductor, and the highest photoresponsivity and photosensitivity to UV light reached 9336 A W−1 and 4429, respectively. This selective and highly sensitive performance enables unsaturated bond‐linked benzo[1,2‐b:4,5‐b′]dithiophene dimers promising candidates for UV detectors.

Spinel‐structured LiMn2O4 (LMO) is a desirable cathode material for Li‐ion batteries due to its low cost, abundance, and high power capability. However, LMO suffers from limited cycle life that is triggered by manganese dissolution into the electrolyte during electrochemical cycling. Here, it is shown that single‐layer graphene coatings suppress manganese dissolution, thus enhancing the performance and lifetime of LMO cathodes. Relative to lithium cells with uncoated LMO cathodes, cells with graphene‐coated LMO cathodes provide improved capacity retention with enhanced cycling stability. X‐ray photoelectron spectroscopy reveals that graphene coatings inhibit manganese depletion from the LMO surface. Additionally, transmission electron microscopy demonstrates that a stable solid electrolyte interphase is formed on graphene, which screens the LMO from direct contact with the electrolyte. Density functional theory calculations provide two mechanisms for the role of graphene in the suppression of manganese dissolution. First, common defects in single‐layer graphene are found to allow the transport of lithium while concurrently acting as barriers for manganese diffusion. Second, graphene can chemically interact with Mn3+ at the LMO electrode surface, promoting an oxidation state change to Mn4+, which suppresses dissolution.

Sodium‐ion battery has captured much attention due to the abundant sodium resources and potentially low cost. However, it suffers from poor cycling stability and low diffusion coefficient, which seriously limit its widespread application. Here, K3V2(PO4)3/C bundled nanowires are fabricated usinga facile organic acid‐assisted method. With a highly stable framework, nanoporous structure, and conductive carbon coating, the K3V2(PO4)3/C bundled nanowires manifest excellent electrochemical performances in sodium‐ion battery. A stable capacity of 119 mAh g−1 can be achieved at 100 mA g−1. Even at a high current density of 2000 mA g−1, 96.0% of the capacity can be retained after 2000 charge–discharge cycles. Comparing with K3V2(PO4)3/C blocks, the K3V2(PO4)3/C bundled nanowires show significantly improved cycling stability. This work provides a facile and effective approach to enhance the electrochemical performance of sodium‐ion batteries.

A unique normalized radial pressure profile characterizes the bed of a gas‐solid vortex reactor over a range of particle densities and sizes, solid capacities, and gas flow rates: 950–1240 kg/m3, 1–2 mm, 2 kg to maximum solids capacity, and 0.4–0.8 Nm3/s (corresponding to gas injection velocities of 55–110 m/s), respectively. The combined momentum conservation equations of both gas and solid phases predict this pressure profile when accounting for the corresponding measured particle velocities. The pressure profiles for a given type of particles and a given solids loading but for different gas injection velocities merge into a single curve when normalizing the pressures with the pressure value downstream of the bed. The normalized—with respect to the overall pressure drop—pressure profiles for different gas injection velocities in particle‐free flow merge in a unique profile. © 2015 The Authors AIChE Journal published by Wiley Periodicals, Inc. on behalf of American Institute of Chemical Engineers AIChE J, 61: 4114–4125, 2015
An integrated framework for scheduling and control using fast model predictive control
Authors: Zhuge Jinjun , Ierapetritou Marianthi G.
Published: June 2015

Integration of scheduling and control involves extensive information exchange and simultaneous decision making in industrial practice (Engell and Harjunkoski, Comput Chem Eng. 2012;47:121–133; Baldea and Harjunkoski I, Comput Chem Eng. 2014;71:377–390). Modeling the integration of scheduling and dynamic optimization (DO) at control level using mathematical programming results in a Mixed Integer Dynamic Optimization which is computationally expensive (Flores‐Tlacuahuac and Grossmann, Ind Eng Chem Res. 2006;45(20):6698–6712). In this study, we propose a framework for the integration of scheduling and control to reduce the model complexity and computation time. We identify a piece‐wise affine model from the first principle model and integrate it with the scheduling level leading to a new integration. At the control level, we use fast Model Predictive Control (fast MPC) to track a dynamic reference. Fast MPC also overcomes the increasing dimensionality of multiparametric MPC in our previous study (Zhuge and Ierapetritou, AIChE J. 2014;60(9):3169–3183). Results of CSTR case studies prove that the proposed approach reduces the computing time by at least two orders of magnitude compared to the integrated solution using mp‐MPC. © 2015 American Institute of Chemical Engineers AIChE J, 61: 3304–3319, 2015
When folic acid fails: Insights from 20 years of neural tube defect surveillance in South Carolina

Published: June 2015

Neural tube defects (NTDs) are the most common of the severe malformations of the brain and spinal cord. Increased maternal intake of folic acid (FA) during the periconceptional period is known to reduce NTD risk. Data from 1046 NTD cases in South Carolina were gathered over 20 years of surveillance. It was possible to determine maternal periconceptional FA use in 615 NTD‐affected pregnancies. In 163 occurrent (26.9%) and two recurrent (22%) NTD cases, the mothers reported periconceptional FA use. These women were older and more likely to be white. Maternal periconceptional FA usage was reported in 40.4% of cases of spina bifida with other anomalies but in only 25.2% of isolated spina bifida cases (P = 0.02). This enrichment for associated anomalies was not noted among cases of anencephaly or of encephalocele. Among the 563 subsequent pregnancies to mothers with previous NTD‐affected pregnancies, those taking FA had a 0.4% NTD recurrence rate, but the recurrence without FA was 8.5%. NTDs with other associated findings were less likely to be prevented by FA, suggesting there is a background NTD rate that cannot be further reduced by FA. Nonetheless, the majority (73.9%) of NTDs in pregnancies in which the mothers reported periconceptional FA use were isolated NTDs of usual types. Cases in which FA failed in prevention of NTDs provide potential areas for further study into the causation of NTDs. The measures and techniques implemented in South Carolina can serve as an effective and successful model for prevention of NTD occurrence and recurrence. © 2015 Wiley Periodicals, Inc.

Chromosomal microdeletions and microduplications are known to cause variable clinical features ranging from apparently normal phenotype to intellectual disability, multiple congenital anomalies, and/or other variable clinical features. 7q11.23 region deletion is the cause for Williams–Beuren syndrome and duplication of same region 7q11.23 causes distinguishable clinical phenotype. Familial inheritance is known for both microdeletion and microduplication of 7q11.23 region. Here, we report a patient of paternally inherited 7q11.23 microduplication with developmental delay, macrocephaly, and structural brain malformations. © 2015 Wiley Periodicals, Inc.

Nervous system development is highly dependent on the function of microtubules, which are assembled from tubulin heterodimers containing several α‐ and β‐tubulin isotypes encoded by separate genes. A spectrum of neurological disorders with malformations of the central nervous system has recently been associated with missense mutations in this group of genes. Here, we report two patients, monozygotic twins, carrying a de novo 0.32 Mb deletion of chromosome 16q24.3 including the TUBB3 gene. The patients presented with global developmental delay, mild facial dysmorphism, secondary microcephaly, and mild spastic diplegia. Cerebral magnetic resonance imaging of the patients did not reveal cortical malformations, malformations of the corticospinal tracts, basal ganglia, corpus callosum, or optic nerves. This observation is in contrast to the group of neurological disorders that are associated with heterozygous missense mutations in genes encoding different neuronal α‐ and β‐tubulin isotypes, termed tubulinopathies. On the background of current knowledge regarding the function and genotype–phenotype correlations of mutations in the neuronal tubulin isotypes, the clinical and diagnostic findings in these patients are discussed. To our knowledge, this is the first report of patients with a de novo deletion of the TUBB3 gene. The lack of cortical or other cerebral malformations supports the current hypothesis that TUBB3‐related tubulinopathies are caused by altered protein function. © 2015 Wiley Periodicals, Inc.
The Multiple Reactions in the Monochlorodimedone Assay: Discovery of Unique Dehalolactonizations under Mild Conditions
Authors: China Hideyasu , Okada Yutaka , Dohi Toshifumi
Published: June 2015

The monochlorodimedone assay has been widely used as an assay of the brominating activity of halogenating enzymes; however, the assumed product was found to spontaneously decompose during the measurement. The decomposition mechanism and systematic error in the assay were explained by five reactions in their multiple reactions. We discovered unique dehalolactonizations of halogenated δ‐keto acids in aqueous solution among many reactions in the assay. Its reaction mechanism was suggested as the cyclization via a cyclopropanone intermediate produced by the intramolecular catalysis of the carboxylate anion.
