Chengdu Qi, Xitao Liu, Yang Li, Chunye Lin, Jun Ma, Xiaowan Li, Huijuan Zhang
In this study, the bisulfite-peroxydisulfate system (S(IV)/PDS) widely used in polymerization was innovatively applied for organic contaminants degradation in water. The addition of S(IV) into PDS system remarkably enhanced the degradation efficiency of bisphenol A (BPA, a frequently detected endocrine disrupting chemical in the environments) from 17.0% to 84.7% within 360 min. The degradation efficiency of BPA in the S(IV)/PDS system followed pseudo-first-order kinetics, with rate constant values ranging from 0...

Aqueous biphasic systems were investigated for the production of formate-amine-adducts via metal-catalyzed CO2-hydrogenation. Different hydrophobic organic solvents and ionic liquids could be employed as the stationary phase for cis-Ru(dppm)2Cl2 as prototypical catalyst without any modification or tagging of the complex. The solvent pair methyl-isobutylcarbinol (MIBC) and water led to the most practical and productive system and repetitive use of the catalyst phase was demonstrated achieving high endurance with a total TON 150...

Ervin Gul, A Nuray Karanci
This study aimed to examine the roles of personality traits, traumatic event types, coping, rumination, and social support in explaining posttraumatic stress symptoms (PTS) and posttraumatic growth (PTG) in a representative community sample of 498 Turkish adults. The results of 2 multiple regression analyses showed that PTS was associated with neuroticism, experiencing events involving intentional/assaultive violence, intrusive and deliberate rumination, and fatalistic coping. In contrast, PTG was related to conscientiousness, openness to experience, injury/shocking and sudden-death type of events, deliberate rumination, problem-solving coping, and perceived social support...

AIMS: This paper discusses the ways researchers may become open to manifold interpretations of lived experience through thematic analysis that follows the tradition of hermeneutic phenomenology. BACKGROUND: Martin Heidegger's thinking about historical contexts of understandings and the notions of 'alētheia' and 'techne' disclose what he called meaning of lived experience, as the 'unchanging Being of changing beings'. While these notions remain central to hermeneutic phenomenological research, novice phenomenologists usually face the problem of how to incorporate these philosophical tenets into thematic analysis...

In the sparse representation model, the design of overcomplete dictionaries plays a key role for the effectiveness and applicability in different domains. Recent research has produced several dictionary learning approaches, being proven that dictionaries learnt by data examples significantly outperform structured ones, e.g. wavelet transforms. In this context, learning consists in adapting the dictionary atoms to a set of training signals in order to promote a sparse representation that minimizes the reconstruction error...

Noncentrosymmetric one dimensional structures are key driving forces behind advanced nanodevices. Owing to the critical role of silane injection in creating nanosized architectures, it has become a challenge to investigate the induced local lattice polarity in single GaN wires. Thus, if axial and radial structures are well-grown by a silane-mediated approach, an ideal model to study their polar orientations is formed. By combining synchrotron X-ray fluorescence and X-ray excited optical luminescence, we show here experimental evidence of the role of silane to promote the N-polarity, light emission and elemental incorporation within single wires...

Evidence suggests that incorporating quantitative reasoning exercises into existent curricular frameworks within the science, technology, engineering, and mathematics (STEM) disciplines is essential for novices' development of conceptual understanding and process skills in these domains. Despite this being the case, such studies acknowledge that students often experience difficulty in applying mathematics in the context of scientific problems. To address this concern, the present study sought to explore the impact of active demonstrations and critical reading exercises on novices' comprehension of basic statistical concepts, including hypothesis testing, experimental design, and interpretation of research findings...

Cancerous tumours have the ability to recruit new blood vessels through a process called angiogenesis. By stimulating vascular growth, tumours get connected to the circulatory system, receive nutrients and open a way to colonize distant organs. Tumour-induced vascular networks become unstable in the absence of tumour angiogenic factors (TAFs). They may undergo alternating stages of growth, regression and regrowth. Following a phase-field methodology, we propose a model of tumour angiogenesis that reproduces the aforementioned features and highlights the importance of vascular regression and regrowth...

Tom Sean Smith, Andreas Heger, Ian Sudbery
Unique Molecular Identifiers (UMIs) are random oligonucleotide barcodes that are increasingly used in high-throughput sequencing experiments. Through a UMI, identical copies arising from distinct molecules can be distinguished from those arising through PCR-amplification of the same molecule. However, bioinformatic methods to leverage the information from UMIs have yet to be formalised. In particular, sequencing errors in the UMI sequence are often ignored, or else resolved in an ad-hoc manner. We show that errors in the UMI sequence are common and introduce network based methods to account for these errors when identifying PCR duplicates...

Introduction The need for open abdomen in the treatment of severely ill neonates will increase in time as more complex abdominal procedures are undertaken. However, the experience of temporary closure of an open abdomen using vacuum-assisted closure (VAC) system is still relatively limited in premature and term neonates. The aim of this study is to describe and review our experience in the use of temporary VAC of the open abdomen for neonates with varying pathological processes. Materials and Methods A retrospective folder review of all neonates treated with VAC for open abdomen over the study period of 2010 to 2014 at our institution was performed...

BACKGROUND: The death notification process can affect family grief and bereavement. It can also affect the well-being of involved physicians. There is no standardized process for making death notification phone calls. We assumed that residents are likely to be unprepared before and troubled after. OBJECTIVE: We investigated current death notification practices to develop an evidence-based template for standardizing this process. DESIGN: We used results of a literature review and open-ended interviews with faculty, residents, and widows to develop a survey regarding resident training and experience in death notification by phone...

Hypoxia can affect various fish populations, including yellow perch Perca flavescens, which is an economically and ecologically important species in Lake Erie, a freshwater system that often experiences hypoxia in the hypolimnetic part of the lake. Fish, similarly to mammals, possess molecular oxygen sensor-hypoxia-inducible factor-1 (HIF-1), a transcription factor that can affect expression of many downstream genes related to animal growth and locomotion, protein synthesis, as well as ATP and amino acid metabolism...

Dopamine D3 receptor (DRD3) is diminished in patients of Parkinson's disease (PD). Brain-derived neurotrophic factor (BDNF) is responsible for regulating expression of the DRD3 in the brain. Our previous study showed that hydroxysafflor yellow A (HSYA) could increase BDNF content in the striatum of PD mice. This experiment aimed to evaluate whether HSYA can improve the motor dysfunction induced by rotenone through regulating the BDNF/TrkB/DRD3 signaling pathway in mice. Male C57/BL6 mice were intraperitoneally treated with HSYA...
