Combined Chemical Activation and Fenton Degradation to Convert Waste Polyethylene into High-Value Fine Chemicals.

Plastic waste is a valuable organic resource. However, proper technologies to recover usable materials from plastic are still very rare. Although the conversion/cracking/degradation of certain plastics into chemicals has drawn much attention, effective and selective cracking of the major waste plastic polyethylene is extremely difficult, with degradation of C-C/C-H bonds identified as the bottleneck.

Early Cognitive Domain Deficits in Patients with Aneurysmal Subarachnoid Hemorrhage Correlate with Functional Status.

Objective: Cognitive deficits commonly occur after aneurysmal subarachnoid hemorrhage (aSAH), although a few studies systemically evaluate its early impact. We hypothesized that early cognitive domain deficits in patients with aSAH correlate with functional status.

Methods: We carried out a prospective observational study in Hong Kong, for which patients with aSAH, aged 21-75 years, who had been admitted within 96 h of ictus were recruited.

Age Moderates the Relationship Between Generativity Concern and Understanding of Wealth.

Background: Wealth can be considered as resource to promote either public welfare (i.e. through altruistic understanding) or personal well-being (i.

Integrated wetlands for food production.

The widespread use of compound pelleted feeds and chemical fertilizers in modern food production contribute to a vast amount of residual nutrients into the production system and adjacent ecosystem are major factors causing eutrophication. Furthermore, the extensive development and application of chemical compounds (such as chemical pesticides, disinfectants and hormones used in enhancing productivity) in food production process are hazardous to the ecosystems, as well as human health. These unsustainable food production patterns cannot sustain human living in the long run.

Perturbational Blowup Solutions to the Two-Component Dullin-Gottwald-Holm System.

We construct a family of nonradially symmetric exact solutions for the two-component DGH system by the perturbational method. Depending on the parameters, the class of solutions includes both blowup type and global existence type.

Seasonal variation in the abundance of marine plastic debris in the estuary of a subtropical macro-scale drainage basin in South China.

Marine plastic debris, including microplastic debris (0.315-5mm) and large plastic debris (>5mm), was collected from 25 beaches in Hong Kong during a wet summer season (June-August 2014) and the following dry winter season (January-March 2015). Wilcoxon signed rank tests were used to compare the abundances and weights of seven categories of plastic debris between the two seasons.

The underlying number-space mapping among kindergarteners and its relation with early numerical abilities.

People map numbers onto space. The well-replicated SNARC (spatial-numerical association of response codes) effect indicates that people have a left-sided bias when responding to small numbers and a right-sided bias when responding to large numbers. This study examined whether such spatial codes were tagged to the ordinal or magnitude information of numbers among kindergarteners and whether it was related to early numerical abilities.

A Novel Balance Training Program for Children With Developmental Coordination Disorder: A Randomized Controlled Trial.

Unlabelled: This study aimed to compare the effectiveness of a specific functional movement-power training (FMPT) program, a functional movement training (FMT) program and no training in the improvement of balance strategies, and neuromuscular performance in children with developmental coordination disorder (DCD). It was a randomized, single-blinded, parallel group controlled trial.

Methods: 161 children with DCD (age: 6-10 years) were randomly assigned to the FMPT, FMT, or control groups.

Probabilistic Phonotactics as a Cue for Recognizing Spoken Cantonese Words in Speech.

Previous experimental psycholinguistic studies suggested that the probabilistic phonotactics information might likely to hint the locations of word boundaries in continuous speech and hence posed an interesting solution to the empirical question on how we recognize/segment individual spoken word in speech. We investigated this issue by using Cantonese language as a testing case in the present study. A word-spotting task was used in which listeners were instructed to spot any Cantonese word from a series of nonsense sound sequences.

Recovery of infrastructure networks after localised attacks.

The stability of infrastructure network is always a critical issue studied by researchers in different fields. A lot of works have been devoted to reveal the robustness of the infrastructure networks against random and malicious attacks. However, real attack scenarios such as earthquakes and typhoons are instead localised attacks which are investigated only recently.

Blowup Phenomenon of Solutions for the IBVP of the Compressible Euler Equations in Spherical Symmetry.

The blowup phenomenon of solutions is investigated for the initial-boundary value problem (IBVP) of the N-dimensional Euler equations with spherical symmetry. We first show that there are only trivial solutions when the velocity is of the form c(t)|x| (α-1) x + b(t)(x/|x|) for any value of α ≠ 1 or any positive integer N ≠ 1. Then, we show that blowup phenomenon occurs when α = N = 1 and [Formula: see text].

Perturbational blowup solutions to the compressible Euler equations with damping.

Background: The N-dimensional isentropic compressible Euler system with a damping term is one of the most fundamental equations in fluid dynamics. Since it does not have a general solution in a closed form for arbitrary well-posed initial value problems. Constructing exact solutions to the system is a useful way to obtain important information on the properties of its solutions.

Explaining medical disputes in Chinese public hospitals: the doctor-patient relationship and its implications for health policy reforms.

In recent years China has witnessed a surge in medical disputes, including many widely reported violent riots, attacks, and protests in hospitals. This is the result of a confluence of inappropriate incentives in the health system, the consequent distorted behaviors of physicians, mounting social distrust of the medical profession, and institutional failures of the legal framework. The detrimental effects of the damaged doctor-patient relationship have begun to emerge, calling for rigorous study and serious policy intervention.

In situ Fabrication of α-Bi2O3/(BiO)2CO3 Nanoplate Heterojunctions with Tunable Optical Property and Photocatalytic Activity.

Exploring the full potential use of heterojunction photocatalysts containing bismuth has attracted considerable interest in recent years. Fabrication of well-defined heterojunction photocatalysts with precise modulation of their chemical composition is crucial for tuning their optical properties and photocatalytic activity. In this study, we fabricated nanoplate α-Bi2O3/(BiO)2CO3 heterojunctions through in situ thermal treatment of (BiO)2CO3 nanoplates synthesized using a facile hydrothermal process.

Method: this was a cross-sectional survey. A convenience sample of 326 currently practicing enrolled nurses (EN) or registered nurses (RN) was recruited.

Non-Traditional Wives With Traditional Husbands: Gender Ideology and Husband-to-Wife Physical Violence in Chinese Society.

Feminist scholars have argued that husband gender traditionalism is one of the root causes of spousal violence against women. Using couple-level data from Hong Kong ( N = 871 couples), this article argues that a second mechanism-couple gender value mismatch-also explains husband-to-wife physical assault. Our findings show that a husband's gender traditionalism is positively associated with husband-to-wife physical assault only when the husband is coupled with a wife who has non-traditional gender attitudes.
