Salinity is one of the most important factors for tidal-affected water bodies including estuaries and tidal river reaches. However, due to the limitations of simultaneous manual monitoring in long-distance areas, studies of estuaries are preferred to tidal reaches. Hence, in this study, we investigated the tidal reach of the Minjiang River and five sets of field observations were used to determine the influence of saltwater intrusion in different seasons. During the dry and wet season with low discharge, the longitudinal salinity profiles showed that a station located about 45 km from the river mouth still suffered from saltwater intrusion especially when the upstream discharge was under 754 m(3) s(-1), where the periodical fluctuation in the salinity remained the same with the water level, but there was a time lag of approximately 4 h compared with the discharge process...

PURPOSE: Referrals to the Emergency Department can be distressing to patients with advanced cancer and may be a non-optimizing health care service. We aimed to describe the appropriateness and potential avoidability of Emergency Department referrals in a tertiary cancer care center where only physician referrals are allowed. METHODS: We prospectively reviewed the electronic medical charts of patients consecutively checked into the Emergency Department in August 2015...

The applicability of a novel macrocyclic multi-carbonyl compound, pillar[4]quinone (P4Q), as the cathode active material for lithium-ion batteries (LIBs) was assessed theoretically. The molecular geometry, electronic structure, Li-binding thermodynamic properties, and the redox potential of P4Q were obtained using density functional theory (DFT) at the M06-2X/6-31G(d,p) level of theory. The results of the calculations indicated that P4Q interacts with Li atoms via three binding modes: Li-O ionic bonding, O-Li···O bridge bonding, and Li···phenyl noncovalent interactions...

BACKGROUND AND PURPOSE: Uncertainty exists over whether quality improvement strategies translate into better health-related quality of life (HRQoL) and survival after acute stroke. We aimed to determine the association of best practice recommended interventions and outcomes after stroke. METHODS: Data are from the Australian Stroke Clinical Registry during 2010 to 2014. Multivariable regression was used to determine associations between 3 interventions: received acute stroke unit (ASU) care and in various combinations with prescribed antihypertensive medication at discharge, provision of a discharge care plan, and outcomes of survival and HRQoL (EuroQoL 5-dimensional questionnaire visual analogue scale) at 180 days, by stroke type...

Purpose In order to prevent adverse events during the discharge process, coordinating appropriate community resources, medication reconciliation, and patient education needs to be implemented before the patient leaves the hospital. This coordination requires communication and effective teamwork amongst staff members. In order to address these concerns, the purpose of this paper is to incorporate the TeamSTEPPS principles to develop a discharge plan that would best meet the needs of the patients as they return to the community...

AIMS AND OBJECTIVES: To identify barriers to adherence with prescribed analgesic regimens in recently discharged trauma patients. BACKGROUND: Trauma pain severely interferes with the life of healthy and often working individuals with intense and enduring pain experienced at home following discharge. The reasons for this are unclear considering discharge information (including discharge referral letters and nursing discharge checklists) and analgesics (scripts and/or medication) are routinely provided to patients at hospital discharge...

Li3VO4 as a promising intercalation-type anode material for lithium-ion batteries features a desired discharge potential (0.5~1.0 V vs. Li/Li+) and a good theoretical storage capacity (590 mAh g-1 with three Li+ inserted). However, the poor electrical conductivity of Li3VO4 hinders its practical application. In the present work, various amounts of oxygen vacancies were introduced in Li3VO4 through annealing in hydrogen to improve its conductivity. To elucidate the influence of oxygen vacancies on the electrochemical performances of Li3VO4, the surface energy of the resulting material was measured via an inverse gas chromatography method...

In this paper ZnCo2O4 nanowall arrays (NWAs) were first obtained through self-assembly followed by calcination. Then atomic layer deposition was used to fabricate core-shell ZnCo2O4@TiO2 NWAs as anode materials for lithium ion batteries (LIBs). The hierarchical NWA nanostructure has fast ion diffusion and electron transport at the electrode/electrolyte interface, while the excellent chemical stability of the TiO2 shell can protect the ZnCo2O4 NWAs from volume expansion during the charge and discharge processes...

Chemical and electrochemical reduction methods allow the dispersion, processing, and/or functionalization of discrete sp(2)-hybridised nanocarbons, including fullerenes, nanotubes and graphenes. Electron transfer to the nanocarbon raises the Fermi energy, creating nanocarbon anions and thereby activating an array of possible covalent reactions. The Fermi level may then be partially or fully lowered by intended functionalization reactions, but in general, techniques are required to remove excess charge without inadvertent covalent reactions that potentially degrade the nanocarbon properties of interest...

Coupling ultrasmall Fe2O3 particles (~4.0 nm) with the MoS2 nanosheets is achieved by a facile method for high-performance anode material for Li-ion battery. MoS2 nanosheets in the composite can serve as scaffolds, efficiently buffering the large volume change of Fe2O3 during charge/discharge process, whereas the ultrasmall Fe2O3 nanoparticles mainly provide the specific capacity. Due to bigger surface area and larger pore volume as well as strong coupling between Fe2O3 particles and MoS2 nanosheets, the composite exhibits superior electrochemical properties to MoS2, Fe2O3 and the physical mixture Fe2O3+MoS2...

OBJECTIVE: To characterize pediatric caregivers' reasons for 72-hour emergency department (ED) and urgent care (UC) returns. METHODS: A sample of caregivers returning within 72 hours of initial visit to a pediatric ED or affiliated UC site were surveyed from 11/14-6/15; patients evaluated at outside ED/UCs, scheduled for return, or non-English/Spanish speaking were excluded. Caregiver surveys underwent item generation, validation, and pilot testing. Survey items included caregiver reasons for unscheduled returns, with a specific assessment of delivery of key components of discharge instructions (diagnosis, duration of illness, home care, return precautions)...

A novel cocoon-like Fe2O3@C nanoparticle was fabricated via a facile hydrothermally molecular self-assembly procedure. Compared to bare Fe2O3 nanoparticles, the carbon coated Fe2O3 nanoparticles exhibit higher specific capacity, excellent rate capacity and cyclic stability as the anode in lithium ion batteries. These cocoon-like Fe2O3@C nanoparticles carry enhanced lithium storage properties with a reversible capacity of 358mAhg(-1) after 150 cycles under the current density of 1000mAg(-1), while the carbon-free bare Fe2O3 can only deliver a much lower capacity of 127...

We report the study of Mg cathodic electrochemical deposition on Ti and Au electrode using a multimodal approach by examining the sample area in-situ using liquid cell transmission electron microscopy (TEM), scanning transmission X-ray microscopy (STXM) and X-ray absorption spectroscopy (XAS). Magnesium Aluminum Chloride Complex was synthesized and utilized as electrolyte, where non-reversible features during in situ charging-discharging cycles were observed. During charging, a uniform Mg film was deposited on the electrode, which is consistent with the intrinsic non-dendritic nature of Mg deposition in Mg ion batteries...

Previous studies show that vanadium oxides suffer from severe capacity loss during cycling in the liquid electrolyte, which has hindered their applications in electrochemical energy storage. The electrochemical instability is mainly due to chemical dissolution and structural pulverization of vanadium oxides during charge/discharge cyclings. In this study the authors demonstrate that amorphous mixed-valence vanadium oxide deposited on exfoliated carbon cloth (CC) can address these two limitations simultaneously...

77 Background: Patients are often overwhelmed at the time of hospital discharge and focus on home rather than the discharge process. Fragmented communication and lack of planning between the hospital team, patient, family and primary oncologist can lead to frustration and delays in implementation of palliative or curative therapies and potential hospital readmission when the plan of care is not followed in a timely manner. Our goal is to avoid medication errors, delays in implementation of a care plan and reemergence of symptoms or new symptoms as a result of a suboptimal discharge transition...

226 Background: Patients undergoing complex oncologic operations are at high risk for perioperative complications associated with adverse effects on quality of life, costs and overall outcomes. Complications within 30 days of discharge are most commonly identified during first 48-72 hours post-discharge. Telephone follow-up can provide a safety net and is part of a larger discharge teaching process. Initial review of the current follow up processes underscored many variations. An interdisciplinary team was tasked to optimize discharge processes across the continuum of care which leads to a more efficient follow-up call encounter...

Tuning the composition of discharge products is an important strategy to reduce charge potential, suppress side reactions, and improve the reversibility of metal-oxygen batteries. In the present study, first-principles calculations and experimental confirmation were performed to unravel the influence of O2 pressure, particle size, and electrolyte on the composition of charge products in Na-O2 batteries. The electrolytes with medium and high donor numbers (>12.5) are favorable for the formation of sole NaO2, while those with low donor numbers (<12...

We simulated the discharge process of Li-O2 batteries and the growth of Li2O2 thin films at the mesoscale with a novel kinetic Monte Carlo model, which combined a stochastic description of mass transport and detailed elementary reaction kinetics. The simulation results show that the ordering of the Li2O2 thin film is determined by the interplay between diffusion and reaction kinetics. Due to the fast reaction kinetics on the catalyst, the Li2O2 formed in the presence of catalyst (cat-CNF) shows a low degree of ordering and is more likely to be amorphous...
