Optimizing Ni-Cr patterned boron-doped diamond band electrodes: Doping effects on electrochemical efficiency and posaconazole sensing performance.

There is growing interest in developing diamond electrodes with defined geometries such as, for example, micrometer-sized electrode arrays to acquire signals for electroanalysis. For electroanalytical sensing applications, it is essential to achieve precise conductive patterns on the insulating surface. This work provides a novel approach to boron-doped diamond patterning using nichrome masking for selective seeding on an oxidized silicon substrate.

Efficient removal of 2,4,6-trinitrotoluene (TNT) from industrial/military wastewater using anodic oxidation on boron-doped diamond electrodes.

With growing public concern about water quality particular focus should be placed on organic micropollutants, which are harmful to the environment and people. Hence, the objective of this research is to enhance the security and resilience of water resources by developing an efficient system for reclaiming industrial/military wastewater and protecting recipients from the toxic and cancerogenic explosive compound-2,4,6-trinitrotoluene (TNT), which has been widely distributed in the environment. This research used an anodic oxidation (AO) process on a boron-doped diamond (BDD) electrode for the TNT removal from artificial and real-life matrices: marine water and treated wastewater.

The composite is composed of commercially available graphene-doped polylactide acid (G-PLA) 3D printouts and surface-functionalized with nanocrystalline boron-doped diamond foil (NDF) additives. The NDFs were synthesized on a tantalum substrate and transferred to the 3D-printout surface at 200 °C.

Bacterial Cellulose Properties Fulfilling Requirements for a Biomaterial of Choice in Reconstructive Surgery and Wound Healing.

Although new therapeutic approaches for surgery and wound healing have recently made a great progress, there is still need for application of better and use novel methods to enhance biocompatibility as well as recovery and healing process. Bacterial Cellulose (BC) is natural cellulose in the form of nanostructure which has the advantages of being used in human body. The medical application of BC in reconstructive, cardiac and vascular surgery as well as wound healing is still under development, but without proved success of repetitive results.

Simultaneous opto-electrochemical monitoring of carbamazepine and its electro-oxidation by-products in wastewater.

The growing human impact on aquatic environments deriving from the extensive use of pharmaceuticals and the release of persistent pollutants necessitates the implementation of new, widespread methods for characterising and quantifying such contaminants and their related degradation products. Carbamazepine, 5 H-dibenzo[b,f]azepine-5-carboxamide, (CBZ) is a widely used anti-epileptic drug characterised by limited removal by conventional wastewater treatments and high persistency in the environment. In this work, CBZ detection and quantification was performed in phosphate buffer, as well as in samples of complex matrix-like landfill leachates and treated wastewater originating from a medical facility, and simultaneously by optical and electrochemical methods using a novel transparent carbon-based nanostructured electrode.

Highly selective impedimetric determination of Haemophilus influenzae protein D using maze-like boron-doped carbon nanowall electrodes.

This study reports a novel impedimetric immunosensor for protein D detection in purified and bacterial (Haemophilus influenzae, Hi) samples. The detection was based on antigen recognition by anti-protein D antibodies (apD) immobilised at the maze-like boron-doped carbon nanowall electrodes (B:CNW). The B:CNW electrodes were synthesised, and their surface was characterised by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) methods.

Electrochemical determination of nitroaromatic explosives at boron-doped diamond/graphene nanowall electrodes: 2,4,6-trinitrotoluene and 2,4,6-trinitroanisole in liquid effluents.

The study is devoted to the electrochemical detection of trace explosives on boron-doped diamond/graphene nanowall electrodes (B:DGNW). The electrodes were fabricated in a one-step growth process using chemical vapour deposition without any additional modifications. The electrochemical investigations were focused on the determination of the important nitroaromatic explosive compounds, 2,4,6-trinitrotoluene (TNT) and 2,4,6-trinitroanisole (TNA).

Charting Directions for Research on Immigrant Children Affected by Undocumented Status.

Three groups of children from Mexico and Central America are vulnerable to effects of US immigration policies: 1) foreign-born children who entered the US with undocumented immigrant parents; 2) unaccompanied children who entered the US alone; and 3) U.S.-born citizen children of undocumented immigrant parents.

The moderating effects of ethnicity on key predictors of trauma in child welfare involved adolescents.

Key predictors of trauma were examined using a multi-group analysis of a nationally representative sample of 716 child welfare involved youth ages 11-17. Results indicate that co-occurring clinical depression was associated with trauma across all racial/ethnic groups. Results also support that youth's ethnicity moderates the relationship between gender, history of sexual abuse and sexual orientation and the development of trauma.

Lesbian, gay, and bisexual (LGB) youth within in welfare: Prevalence, risk and outcomes.

The purpose of this study was to estimate the population of sexual minority or LGB (lesbian, gay and bisexual) children and youth involved with the child welfare system, and to compare their health, mental health, placement and permanency outcomes to those of non-LGB youth. Data were drawn from the Second National Survey of Child and Adolescent Well-Being (NSCAW-II), a nationally representative sample of children who were referred to child welfare due to a report of abuse or neglect over a fifteen month period. This sample included youth ages eleven and older who self-identified their sexual orientation (n = 1095).

Nucleosome positioning in the regulatory region of SV40 chromatin correlates with the activation and repression of early and late transcription during infection.

The location of nucleosomes in SV40 virions and minichromosomes isolated during infection were determined by next generation sequencing (NGS). The patterns of reads within the regulatory region of chromatin from wild-type virions indicated that micrococcal nuclease-resistant nucleosomes were specifically positioned at nt 5223 and nt 363, while in minichromosomes isolated 48 h post-infection we observed nuclease-resistant nucleosomes at nt 5119 and nt 212. The nucleosomes at nt 5223 and nt 363 in virion chromatin would be expected to repress early and late transcription, respectively.

Cultural adaptations to augment health and mental health services: a systematic review.

Background: Membership in diverse racial, ethnic, and cultural groups is often associated with inequitable health and mental health outcomes for diverse populations. Yet, little is known about how cultural adaptations of standard services affect health and mental health outcomes for service recipients. This systematic review identified extant themes in the research regarding cultural adaptations across a broad range of health and mental health services and synthesized the most rigorous experimental research available to isolate and evaluate potential efficacy gains of cultural adaptations to service delivery.

Effects of Parent Immigration Status on Mental Health Service Use Among Latino Children Referred to Child Welfare.

Objective: Latino families may be at risk of experiencing stressors resulting from the immigration process, such as those related to documentation status and acculturation, that may increase their need for mental health services. However, little research exists on the mental health needs and service use of Latino children. This study examined how parental nativity and legal status influence mental health needs and service utilization among children in Latino families investigated by child welfare.

Concentration and sources of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in surface soil near a municipal solid waste (MSW) landfill.

Due to a continuous demand of land for infrastructural and residential development there is a public concern about the condition of surface soil near municipal solid waste landfills. A total of 12 surface (0-20 cm) soil samples from a territory near a landfill were collected and the concentration of 16 PAHs and 7 PCB congeners were investigated in these samples. Limits of detection were in the range of 0.

Development of an instrument to understand the child protective services decision-making process, with a focus on placement decisions.

When children come to the attention of the child welfare system, they become involved in a decision-making process in which decisions are made that have a significant effect on their future and well-being. The decision to remove children from their families is particularly complex; yet surprisingly little is understood about this decision-making process. This paper presents the results of a study to develop an instrument to explore, at the caseworker level, the context of the removal decision, with the objective of understanding the influence of the individual and organizational factors on this decision, drawing from the Decision Making Ecology as the underlying rationale for obtaining the measures.

The Decision Making Ecology of placing a child into foster care: A structural equation model.

The Decision Making Ecology provided a framework for empirically testing the impact of Case, Caseworker and Organizational factors on the decision to place children in out-of-home care. The structural equation model we developed fit the data extremely well, indicating a complex relationship between the variables. The main findings indicate that Case factors, even as aggregated to the worker level, were of most importance: Percent Removed was increased in part by greater average Risk being assessed and more families on a worker's caseload being Low Income.

Disparities in reported and substantiated infant maltreatment by maternal Hispanic origin and nativity: a birth cohort study.

We followed Latino infants prospectively through age 1 to determine whether maternal foreign-born status conferred a protective advantage against reported and substantiated maltreatment across Hispanic-origin groups, and whether the likelihood an infant was reported or substantiated for maltreatment varied by Hispanic origin. We drew data for all Latino infants born in California between 2000 and 2006 (N = 1,909,155) from population-based birth records linked to child protective services data. We used χ(2) tests to assess distributional differences in covariates and utilized generalized linear models to estimate the adjusted relative risk of report and substantiation in models stratified by nativity.

Cortical activity associated with the perception of temporal asymmetry in ramped and damped noises.

Human listeners are very sensitive to the asymmetry of time-reversed pairs of ramped and damped sounds. When the carrier is noise, the hiss -component of the perception is stronger in ramped sounds and the drumming component is stronger in damped sounds (Akeroyd and Patterson 1995). In the current study, a paired comparison technique was used to establish the relative "hissiness" of these noises, and the ratings were correlated with (a) components of the auditory evoked field (AEF) produced by these noises and (b) the magnitude of a hissiness feature derived from a model of the internal auditory images produced by these noises (Irino and Patterson 1998).

Substitute care entry: the relationship between race or ethnicity and levels of county organization.

Objective: Past studies demonstrate a relationship between race and the likelihood of children entering state custody subsequent to a maltreatment investigation. Research also shows that community structural characteristics such as poverty and residential mobility are correlated with entry rates. The combined effect, however, of race and community characteristics on substitute care entry is unclear.

Conducting culturally competent evaluations of child welfare programs and practices.

As the population of the United States has changed over the last two decades, so has the population of children who come to the attention of the child welfare system, resulting in increasing calls for cultural competence in all aspects of child welfare programming and practice. Given the changing demographics among children involved in the child weltare system and the increasing need to address the racial and ethnic disparities observed in this system, the need for culturally competent approaches to evaluate the outcomes of services for children and families is essential. This article discusses the challenges in conducting culturally competent evaluations and provides strategies to address those challenges within a child welfare context.

Factors contributing to disproportionality in the child welfare system: views from the legal community.

A critical shortcoming in the existing body of research addressing racial disproportionality in the child welfare system is the lack of inclusion of external stakeholders in attempts to understand and address this issue.This article reports the results ofa study designed to develop a deeper understanding of disproportionality from the views of the legal community, a critical stakeholder in child welfare. Using a qualitative approach, with focus groups as the method of data collection, data were collected to provide a greater depth of information that could be used alongside existing studies to develop an enhanced understanding of disproportionality in the child welfare system.
