A likely role for stratification in long-term changes of the global ocean tides.

Stratification-that is, the vertical change in seawater density-exerts a subtle control on the energetics and thus the surface elevation of barotropic (depth independent) flows in the ocean. Changes in stratification therefore provide a plausible pathway to explain some of the puzzling trends in ocean tides evident in tide gauge and, more recently, satellite altimetry data. Using a three-dimensional global ocean model, we estimate that strengthening of stratification between 1993 and 2020 caused open-ocean trends of order 0.

Compressibility of expansive soil mixed with sand and its correlation to index properties.

Prior research has primarily focused on Atterberg limits, void ratios, and/or water content, often disregarding the impact of coarse material percentage in the soil, which significantly affects compressibility behavior. This paper examines the effects of sand content, initial degree of saturation, and initial dry unit weight on the compressibility behavior of expansive soils. Ninty-six oedometer tests were performed in order to accurately predict the compressibility behavior of expansive soils.

The mean seasonal cycle in relative sea level from satellite altimetry and gravimetry.

Satellite altimetry and gravimetry are used to determine the mean seasonal cycle in relative sea level, a quantity relevant to coastal flooding and related applications. The main harmonics (annual, semiannual, terannual) are estimated from 25 years of gridded altimetry, while several conventional altimeter "corrections" (gravitational tide, pole tide, and inverted barometer) are restored. To transform from absolute to relative sea levels, a model of vertical land motion is developed from a high-resolution seasonal mass inversion estimated from satellite gravimetry.

Effects of mechanical ventilation and portable air cleaner on aerosol removal from dental treatment rooms.

Objectives: To evaluate the mechanical ventilation rates of dental treatment rooms and assess the effectiveness of aerosol removal by mechanical ventilation and a portable air cleaner (PAC) with a high-efficiency particulate air (HEPA) filter.

Methods: Volumetric airflow were measured to assess air change rate per hour by ventilation (ACH). Equivalent ventilation provided by the PAC (ACH) was calculated based on its clean air delivery rate.

First global observations of third-degree ocean tides.

The Moon's tidal potential is slightly asymmetric, giving rise to so-called third-degree ocean tides, which are small and never before observed on a global scale. High-precision satellite altimeters have collected sea level records for almost three decades, providing a massive database from which tiny, time-coherent signals can be extracted. Here, four third-degree tides are mapped: one diurnal, two semidiurnal, and one terdiurnal.

Delineating Quality Indicators of Inpatient Psychiatric Hospitalization.

Background: Assuring quality care is critical to the well-being and recovery of individuals receiving inpatient psychiatric treatment, yet a comprehensive map of quality inpatient care does not exist.

Aims: To isolate and describe quality elements of inpatient psychiatric treatment.

Methods: A survey queried psychiatric inpatient nursing leaders on what they considered to be critical elements of quality.

Understanding of Contemporary Regional Sea-Level Change and the Implications for the Future.

Global sea level provides an important indicator of the state of the warming climate, but changes in regional sea level are most relevant for coastal communities around the world. With improvements to the sea-level observing system, the knowledge of regional sea-level change has advanced dramatically in recent years. Satellite measurements coupled with in situ observations have allowed for comprehensive study and improved understanding of the diverse set of drivers that lead to variations in sea level in space and time.

Aliased Tidal Variability in Mesoscale Sea Level Anomaly Maps.

Sea level anomaly (SLA) maps are routinely produced by objective analysis of data from the constellation of satellite altimeter missions in operation since 1992. Beginning in 2014, changes in the Data Unification and Altimeter Combination System (DUACS) used to create the SLA maps resulted in improved spatial resolution of mesoscale variability, but it also increased the levels of aliased tidal variability compared to the methodology employed prior to 2014. The present work investigates the magnitude and spatial distribution of these tidal signals, which are typically smaller than 1 cm in the open ocean but can reach tens of centimeters in the coastal ocean.

The Impact of Nursing Protocols on Continuous Special Observation.

Background: Continuous Special Observation (CSO) is commonly ordered for patients at risk to injure themselves or others and involves assigning staff to monitor one patient at all times. CSO is intrusive, costly, and often has deleterious effects on patient care. Two nursing protocols were developed as alternative interventions to CSO.

The extracellular domain of myelin oligodendrocyte glycoprotein elicits atypical experimental autoimmune encephalomyelitis in rat and Macaque species.

Atypical models of experimental autoimmune encephalomyelitis (EAE) are advantageous in that the heterogeneity of clinical signs appears more reflective of those in multiple sclerosis (MS). Conversely, models of classical EAE feature stereotypic progression of an ascending flaccid paralysis that is not a characteristic of MS. The study of atypical EAE however has been limited due to the relative lack of suitable models that feature reliable disease incidence and severity, excepting mice deficient in gamma-interferon signaling pathways.

Issues for storing plant-based alternative fuels in marine environments.

Two coastal seawaters (Key West, FL, USA and the Persian Gulf, Bahrain, representing oligotrophic and eutrophic environments, respectively) were used to evaluate potential biodegradation and corrosion problems during exposure to alternative and conventional fuels. Uncoated carbon steel was exposed at the fuel/seawater interface and polarization resistance was monitored. Under typical marine storage conditions, dioxygen in natural seawater exposed to fuel and carbon steel was reduced to <0.

Iron cycling at corroding carbon steel surfaces.

Surfaces of carbon steel (CS) exposed to mixed cultures of iron-oxidizing bacteria (FeOB) and dissimilatory iron-reducing bacteria (FeRB) in seawater media under aerobic conditions were rougher than surfaces of CS exposed to pure cultures of either type of microorganism. The roughened surface, demonstrated by profilometry, is an indication of loss of metal from the surface. In the presence of CS, aerobically grown FeOB produced tight, twisted helical stalks encrusted with iron oxides.

Shewanella frigidimarina microbial fuel cells and the influence of divalent cations on current output.

The genes involved in the proposed pathway for Shewanella extracellular electron transfer (EET) are highly conserved. While extensive studies involving EET from a fresh water Shewanella microbe (S. oneidensis MR-1) to soluble and insoluble electron acceptors have been published, only a few reports have examined EET from marine strains of Shewanella.

Sulphide production and corrosion in seawaters during exposure to FAME diesel.

Experiments were designed to evaluate the corrosion-related consequences of storing/transporting fatty acid methyl ester (FAME) alternative diesel fuel in contact with natural seawater. Coastal Key West, FL (KW), and Persian Gulf (PG) seawaters, representing an oligotrophic and a more organic- and inorganic mineral-rich environment, respectively, were used in 60 day incubations with unprotected carbon steel. The original microflora of the two seawaters were similar with respect to major taxonomic groups but with markedly different species.

The evolution of practice changes in the use of special observations.

In acute psychiatric settings, it is common practice to increase the intensity of observations of patients who present with self-injurious thoughts, who are at risk of injuring others, or who exhibit behaviors that adversely impact the overall milieu. These intense observations are intrusive and may result in untoward stimulation of the patient. Nurses at an urban academic medical center addressed the problem of intrusive and overstimulating levels of observation by developing two practice changes using intuitive knowledge combined with input from current nursing literature.

Neutrophilic iron-oxidizing "zetaproteobacteria" and mild steel corrosion in nearshore marine environments.

Microbiologically influenced corrosion (MIC) of mild steel in seawater is an expensive and enduring problem. Little attention has been paid to the role of neutrophilic, lithotrophic, iron-oxidizing bacteria (FeOB) in MIC. The goal of this study was to determine if marine FeOB related to Mariprofundus are involved in this process.

An assessment of alternative diesel fuels: microbiological contamination and corrosion under storage conditions.

Experiments were designed to evaluate the nature and extent of microbial contamination and the potential for microbiologically influenced corrosion of alloys exposed in a conventional high sulfur diesel (L100) and alternative fuels, including 100% biodiesel (B100), ultra-low sulfur diesel (ULSD) and blends of ULSD and B100 (B5 and B20). In experiments with additions of distilled water, all fuels supported biofilm formation. Changes in the water pH did not correlate with observations related to corrosion.

A neonate with microphthalmia and median clefting of the lower lip and mandible.

Median clefts of the lower lip and mandible are very rare congenital anomalies. We report a female infant born to nonconsanguineous parents with unilateral microphthalmia and complete median clefting of the lower lip and mandible. This uncommon constellation of congenital malformations has never been reported in a liveborn infant.

A galactose polyacrylate-based hydrogel scaffold for the detection of cholera toxin and staphylococcal enterotoxin B in a sandwich immunoassay format.

A galactoside-based polyacrylate hydrogel was used as a scaffold to immobilize antibodies for the development of a sandwich immunoassay to detect cholera toxin (CT) and staphylococcal enterotoxin B (SEB). The hydrogel possesses large pores and simulates a solution-like environment allowing easy penetration of large biomolecules. Highly crosslinked hydrogels containing pendant amine or carboxyl functionalities were polymerized through a free-radical polymerization process.
