Spatiotemporal effects of interacting water quality constituents on mercury in a common prey fish in a large, perturbed, subtropical wetland.

Sci Total Environ 2021 Jun 9;792:148321. Epub 2021 Jun 9.

United States Environmental Protection Agency, Office of Research and Development, Center for Public Health and Environmental Assessment, Public Health and Environmental Systems Division, Research Triangle Park, 109 TW Alexander Drive, Durham, NC 27709, USA.

We present results of a multiyear study of the Everglades (Florida, USA) detailing how differences in environmental variables can alter mercury concentrations in the food web. About 1000 random locations throughout the freshwater Everglades marsh have been sampled for the United States Environmental Protection Agency's Everglades Regional Environmental Monitoring and Assessment Program ("REMAP") since 1995. REMAP sampling is synoptic and multimedia, including an abundant prey fish (eastern mosquitofish, Gambusia holbrooki) as an indicator of mercury bioaccumulation. Read More

Animal 2021 Jun 15;15(7):100221. Epub 2021 Jun 15.

ADM Animal Nutrition, Decatur, IL 62521, USA.

Limited information is available on lysine requirement estimates of modern, high-producing gestating sows Therefore, the objective of this study was to evaluate the effects of increasing standardized ileal digestible (SID) lysine during gestation on piglet birthweight and reproductive performance of gilts and sows. A total of 936 females (498 gilts, 438 sows; Camborough®, PIC, Hendersonville, TN) were group-housed (approximately 275 females per pen) and individually fed with electronic sow feeders.

Substance Use Trajectories: Nonmedical Use (NMU) of Prescription Stimulants via Non-Oral Routes of Administration Among Adults Recruited from Reddit.

CNS Spectr 2021 Apr;26(2):166-167

Syracuse University, Syracuse, NY, USA.

NMU of prescription stimulant medications (RxStim) intended for treatment of attention deficit/hyperactivity disorder (ADHD) is a growing public health concern, particularly when used via non-oral routes of administration. However, the role of non-oral routes of administration for RxStim NMU in the larger substance abuse pathway is less well studied.

Br J Sociol 2021 Jun 3. Epub 2021 Jun 3.

Department of Sociology, New York University, New York, NY, USA.

Understanding changes in the structure of public opinion is necessary to evaluate both contemporary claims about political divisions in Brexit Britain, as well as to uncover any long-term mapping of public opinion on the depolarization and subsequent polarization of elites from the birth of New Labour to the aftermath of the Great Recession. I assess trends from British Social Attitudes surveys, utilizing recent conceptual and methodological distinctions between different features of public opinion change. I find that the public, on average, moved to the left during the early 1990s, to the right during New Labour, and back to the left from 2010. Read More

Household solid waste combustion with wood increases particulate trace metal and lung deposited surface area emissions.

J Environ Manage 2021 May 28;293:112793. Epub 2021 May 28.

Aerosol Physics Laboratory, Physics Unit, Tampere University, P.O. Box 692, 33014, Tampere, Finland.

In households, municipal solid waste (MSW) is often burned along with wood to get rid of waste, to help in ignition or simply to reduce fuel costs. The aim of this study was to characterize the influence of household waste combustion, along with wood, on the physical and chemical properties of particulate emissions in a flue gas of a masonry heater. The MSW burning alongside wood increased average particulate matter (PM) mass (65%), lung deposited surface areas (LDSA, 15%), black carbon (BC, 65%) concentrations and the average particle size in the flue gas.

Glob Chang Biol 2021 May 21. Epub 2021 May 21.

Program in Ecology, University of Wyoming, Laramie, WY, USA.

Fire-prone dry forests often face increasing fires from climate change with low resistance and resilience due to logging of large, old fire-resistant trees. Their restoration across large landscapes is constrained by limited mature trees, physical settings, and protection. Active restoration has been costly and shown limited effectiveness, but lower cost passive restoration is less studied. Read More

We study the role of person- and place-specific factors in explaining geographic variation in emergency department utilization using detailed data on 150,000 patients who moved regions within Israel. We document that about half of the destination-origin differences in the average emergency department utilization rate across districts translates to the change (up or down) in movers' propensity to visit the emergency department. In contrast, we find no change in the probability of having a hospital admission through the emergency department. Read More

Experimental study on the effects of blending PODE on performance, combustion and emission characteristics of heavy-duty diesel engines meeting China VI emission standard.

Sci Rep 2021 May 4;11(1):9514. Epub 2021 May 4.

Air and Missile Defense College, Air Force Engineering University, Xi'an, 710051, People's Republic of China.

To study the influence of diesel fuel blended with polyoxymethylene dimethyl ethers (PODE), a new alternative fuel with a high oxygen content and large cetane number, on the combustion characteristics, fuel economies, and emission characteristics of heavy-duty diesel engines that meet China VI emission standards, relevant tests were conducted on a supercharged intercooled high-pressure common-rail diesel engine. The PODE were blended with diesel fuel at three different ratios (volume fractions of 10%, 20%, and 30%). The test results showed that the PODE could optimize the combustion process of diesel engines that met the China VI emission standards, effectively improve the thermal efficiencies of diesel engines, and reduce the emissions of hydrocarbon (HC), carbon monoxide (CO), and soot.

The virtual loss function in the summary perception of motion and its limited adjustability.

J Vis 2021 May;21(5)

Peking-Tsinghua Center for Life Sciences, Peking University, Beijing, China.

Humans can grasp the "average" feature of a visual ensemble quickly and effortlessly. However, it is largely unknown what is the exact form of the summary statistic humans perceive and it is even less known whether this form can be changed by feedback. Here we borrow the concept of loss function to characterize how the summary perception is related to the distribution of feature values in the ensemble, assuming that the summary statistic minimizes a virtual expected loss associated with its deviation from individual feature values.

A Preliminary Investigation of Social Network Analysis Applied to Dairy Cow Behavior in Automatic Milking System Environments.

Animals (Basel) 2021 Apr 24;11(5). Epub 2021 Apr 24.

Department of Animal and Dairy Sciences, University of Wisconsin-Madison, Madison, WI 53706, USA.

We have applied social network analysis (SNA) to data on voluntary cow movement through a sort gate in an automatic milking system to identify pairs of cows that repeatedly passed through a sort gate in close succession (affinity pairs). The SNA was applied to social groups defined by four pens on a dairy farm, each served by an automatic milking system (AMS). Each pen was equipped with an automatic sorting gate that identified when cows voluntarily moved from the resting area to either milking or feeding areas. Read More

Individualized sleep promotion in acute care hospitals: managing specific factors that affect patient sleep.

Mhealth 2021 20;7:25. Epub 2021 Apr 20.

Department of Medicine, Brigham and Women's Hospital, Boston, USA.

Background: Improving sleep for hospitalized patients is an essential clinical need. Compared to the traditional "one-size-fits-all" interventions designed by clinicians for all patients, an individualized strategy engaging patients to identify salient sleep disruptors and seek their input how to address these disruptors are more likely to succeed. Followed by our work of developing the Factors Affecting Inpatient Sleep (FAIS) scale, in this report we developed a set of icons illustrating 14 common sleep disruptors on the FAIS scale, and proposed behavioral sleep promotion tips addressing each sleep disruptor.
