Emission models are widely applied tools for estimating atmospheric emissions from wastewater treatment plants (WWTPs). The friction velocity u∗ is a key variable for the modelling of emissions from passive liquid surfaces in WWTPs. This work evaluated different parametrisations of u∗ for passive liquid surfaces at the scale of WWTP units, which present relatively small fetches, based on available wind friction and wave data measured at wind-wave tanks (fetches spanning from approximately 3 to 100 m, and wind speeds from 2 to 17 m s(-1))...

This paper describes the introduction of a thin titanium dioxide interlayer that serves as passivation layer and dopant source for hematite (α-Fe2O3) nanoarray photoanode. This interlayer is demonstrated to boost the photocurrent by suppressing the substrate/hematite interfacial charge recombination, and increase the electrical conductivity by enabling Ti4+ incorporation. A dendritic nanostructure of this photoanode with enhanced solid-liquid junction area further improves to the surface charge collection efficiency, generating a photocurrent of ~2...

OBJECTIVES: We hypothesize that the anatomic center of the distal tibia is just lateral and anterior to the center of the distal tibia articular surface in the coronal and sagittal planes respectively, and that placement of the nail along this axis results in improved rates of malalignment when treating distal tibia fractures. DESIGN: Retrospective study SETTING:: One level I and one level II trauma center PATIENTS/PARTICIPANTS:: 203 distal tibia fractures treated with IMN (primary cohort) whose main fracture line extended within 5 cm of the plafond to evaluate the rate of malalignment with distal nail placement...

OBJECTIVE: This study evaluates the current state of the General Surgery (GS) residency training model by investigating resident operative performance and autonomy. BACKGROUND: The American Board of Surgery has designated 132 procedures as being "Core" to the practice of GS. GS residents are expected to be able to safely and independently perform those procedures by the time they graduate. There is growing concern that not all residents achieve that standard. Lack of operative autonomy may play a role...

PURPOSE OF REVIEW: Intimate behaviours may represent an unusual way of exposure to a culprit allergen, or the frame for sex-related allergies due to triggers typically linked to that situation. The present review aims at summarizing the state of the art about the topic, in order to spread the awareness and the basic know-how in the field of sexual-related allergies. RECENT FINDINGS: Kiss-related IgE-mediated reactions are caused in sensitized partners mainly by the passive transport of allergenic molecules through saliva, skin or oral mucosa...

We develop a model to describe the behavior of a system of active and passive particles in solution that can undergo spontaneous self-organization and self-sustained motion. The active particles are uniformly coated with a catalyst that decomposes the reagent in the surrounding fluid. The resulting variations in the fluid density give rise to a convective flow around the active particles. The generated fluid flow, in turn, drives the self-organization of both the active and passive particles into clusters that undergo self-sustained propulsion along the bottom wall of a microchamber...

Highly fluorescent and amphiphilic carbon quantum dots (CQDs) were prepared by microwave-assisted pyrolysis of citric acid and 4,7,10-trioxa-1,13-tridecanediamine (TTDDA), which functioned as an A3 and B2 polyamidation type monomer set. Gram quantities of fluorescent CQDs were easily obtained within 5 min of microwave heating using a household microwave oven. Because of the dual role of TTDDA, both as a constituting monomer and as a surface passivation agent, TTDDA-based CQDs showed a high fluorescence quantum yield of 29% and amphiphilic solubility in various polar and non-polar solvents...

BACKGROUND: Unintentional perioperative hypothermia causes serious adverse effects to surgical patients. Thermal suit (T-Balance(®) ) is an option for passive warming perioperatively. We hypothesized that the thermal suit will not maintain normothermia more efficiently than conventional cotton clothes when also other preventive procedures against unintentional hypothermia are used. METHODS: One hundred patients were recruited to this prospective, randomized trial...

Challenge: Although lecturing is an efficient method for the dissemination of information, it has long been criticized for learner passivity and diminished knowledge retention. Active learning strategies to engage the audience in the learning process can facilitate a bidirectional flow of ideas and content between teacher and students during a lecture to keep learners engaged and participating.

REVIEW
Amanda W Lund
Lymphatic vessels facilitate fluid homeostasis, immune cell trafficking, and lipid transport, and contribute to solid tumor progression as routes of metastasis. Given new evidence that lymphatic vessels both correlate with intratumoral lymphocytes and directly suppress immune function, I reevaluate the passive lymphatic vessel paradigm and discuss its relevance to antitumor immunity.

BACKGROUND: Whole body vibration (WBV) exercises have been investigated as an alternative and complementary method to traditional resistance programs for fitness improvements in healthy subjects. Active militaries must have a high fitness level and have to improve some physical abilities to accomplish some specific tasks in Army, as climb ropes, climb walls and pull up. MATERIALS AND METHODS: Seven young and healthy soldiers from Brazilian Army were exposed to mechanical vibration in a push-up position, with different frequencies, as 25 (first session), 30 (second session), 35 (third session), 40 (fourth session) and 45 Hz (fifth session)...

Determining the effector populations involved in humoral protection against genital chlamydia infection is crucial to development of an effective chlamydial vaccine. Antibody has been implicated in protection studies in multiple animal models, and we previously showed that the passive transfer of immune serum alone does not confer immunity in the mouse. Using the Chlamydia muridarum model of genital infection, we demonstrate a protective role for both Chlamydia-specific immunoglobulin (Ig) G and polymorphonuclear neutrophils, and show the importance of an antibody/effector cell interaction in mediating humoral immunity...

Polybrominated diphenyl ethers are widely used flame retardants which persist and diffuse in the environment thus entering the food chain. Eight congeners, most relevant for human exposure (BDE-28, 47, 99, 100, 153, 154, 183 and 209), were analyzed in vitro and in silico to derive a relative toxicological ranking. Cytotoxicity was assessed on human liver (HepG2) and colon (DLD-1) cell lines, by three assays (MTS, ATP and DNA content) in a range of realistic concentration (1pM - 10 nM). Jejunum and Caco-2 passive absorptions were calculated in silico...

Proceeding from a biophysical network model, the present study hypothesized that glutamatergic neurotransmission across the NMDA receptor (NMDAR) plays a key role in visual perception and its modulation by acute stress. To investigate these hypotheses, behavioral and electroencephalographic (EEG) indicators of partial report task processing were assessed in twenty-four healthy young men who randomly received a non-competitive NMDAR antagonist (0.8 mg/kg dextromethorphan, DXM) or a placebo, and concurrently accomplished a stress-induction (MAST) or control protocol in three consecutive sessions...

Previous research has shown that children demonstrate similar sentence processing reflexes to those observed in adults, but they have difficulties revising an erroneous initial interpretation when they process garden-path sentences, passives, and wh-questions. We used the visual-world paradigm to examine children's use of syntactic and non-syntactic information to resolve syntactic ambiguity by extending our understanding of number features as a cue for interpretation to which-subject and which-object questions...

BACKGROUND: Inflammation during brain development participates in the pathogenesis of early brain injury and cognitive dysfunctions. Prenatal ethanol exposure affects the developing brain and causes neural impairment, cognitive and behavioral effects, collectively known as fetal alcohol spectrum disorders (FASD). Our previous studies demonstrate that ethanol activates the innate immune response and TLR4 receptor and causes neuroinflammation, brain damage, and cognitive defects in the developmental brain stage of adolescents...

Structural abnormalities on MRI are frequent after an ankle sprain. To determine the association between patient history, physical examination and early osteoarthritis (OA) in patients after a previous ankle sprain, 98 patients with persistent complaints were selected from a cross-sectional study. Patient history taking and physical examination were applied and MRI was taken. Univariate and multivariable analyses were used to test possible associations. Signs of OA (cartilage loss, osteophytes and bone marrow edema) were seen in the talocrural joint (TCJ) in 40% and the talonavicular joint (TNJ) in 49%...

Yu-Shu Huang, Christian Guilleminault
Pediatric obstructive sleep apnea (OSA) was initially described in 1976. In 1981, Dr. Guilleminault emphasized that pediatric OSA was different from the clinical presentation reported in adults. It was characterized by more disturbed nocturnal sleep than excessive daytime sleepiness, and presented more behavioral problems, particularly school problems, hyperactivity, nocturnal enuresis, sleep terrors, depression, insomnia, and psychiatric problems. The underlying causes of pediatric OSA are complex. Such factors as adenotonsillar hypertrophy, obesity, anatomical and neuromuscular factors, and hypotonic neuromuscular disease are also involved...
