Why Do Things Burn? Elizabeth Fulhame's Challenge to the Antiphlogistic Theory of Combustion.

Motivated by her interest in fabric arts, late-eighteenth-century British chemist Elizabeth Fulhame experimentally investigated whether cloths of gold, silver, and other metals could be made by chemical rather than mechanical processes. In contrast to other women studying science at this time, she not only published an original monograph under her own name that challenged both the phlogistic and antiphlogistic views of combustion but also proposed an alternative explanation for oxidation and reduction. Although her contemporaries widely cited her innovative research, her history is not well known, yet a careful analysis of her work provides further insights into the reception of the antiphlogistic theory and the challenges and limitations experienced by women in chemistry during this period.

The Relationship of Pain Intensity, Perceived Injustice, and Pain Catastrophizing to Heart Rate Variability In Naturally Occurring Acute Pain.

Objectives: Behavioral factors of pain catastrophizing and perceived injustice are associated with pain intensity in chronic pain. Diminished heart rate variability (HRV) is also strongly associated with chronic pain. These factors have been less explored earlier in the pain experience and it is unclear whether they play a role in the transition from acute to chronic pain.

A key factor in monitoring cannabis consumption trends through wastewater analysis: Partitioning of THCCOOH between the liquid and solid phase of influent wastewater.

Current wastewater-based epidemiology (WBE) studies are predominantly focused on the analysis of urinary biomarkers present in the liquid phase of influent wastewater (IWW). This approach systematically underestimates less polar metabolites, such as cannabis biomarkers. These biomarkers can potentially sorb to and desorb from suspended particulate matter (SPM) present in IWW.

Temporal expression of mitochondrial life cycle markers during acute and chronic overload of rat plantaris muscles.

Skeletal muscle hypertrophy is generally associated with a fast-to-slow phenotypic adaptation in both human and rodent models. Paradoxically, this phenotypic shift is not paralleled by a concomitant increase in mitochondrial content and aerobic markers that would be expected to accompany a slow muscle phenotype. To understand the temporal response of the mitochondrial life cycle (i.

Positive intonation increases the perceived value of smaller rewards in a quantity discrimination task with dogs (Canis familiaris).

Like many other species, dogs have a natural quantity judgment system to assist with decision making to maximize resources. Additionally, dogs are highly sensitive to, and influenced by, human-delivered ostensive (i.e.

Dispersal distances from splash-cup plants depend on the cup's angle and contents.

Splash-cup plants disperse propagules via raindrops striking cup-shaped fruiting bodies. The seeds are ejected at velocities up to five times the impact speed of the raindrop and are dispersed up to 1 m from the parent plant. Here, we examine the effects of cup angles and the presence of seed mimics to understand the dynamics of this unique method of dispersal.

Exploring the Efficacy of a Dynamic Harness System on Gross Motor Development and Motivation for Infants With Down Syndrome: A Pilot Study.

Purpose: To explore the benefits of a Partial Body Weight Support (PBWS) harness system within a play enriched environment on gross motor development and mastery motivation of infants with Down Syndrome (DS).

Methods: A randomized crossover study with 17 pre-walking infants with DS in two conditions-play with or without the harness engaged-each for 3×/week over 3 weeks with a 1-week washout. Assessments took place at baseline, crossover, and completion.

The effect of external flow on 3D orientation of a microscopic sessile suspension feeder, Vorticella convallaria.

Vorticella convallaria are microscopic sessile suspension feeders that live attached to substrates in aquatic environments. They feed using a self-generated current and help maintain the health of aquatic ecosystems and wastewater treatment facilities by consuming bacteria and detritus. Their environmental impact is mediated by their feeding rate.

Current state and future perspectives on de facto population markers for normalization in wastewater-based epidemiology: A systematic literature review.

Wastewater-based epidemiology (WBE) and wastewater surveillance have become a valuable complementary data source to collect information on community-wide exposure through the measurement of human biomarkers in influent wastewater (IWW). In WBE, normalization of data with the de facto population that corresponds to a wastewater sample is crucial for a correct interpretation of spatio-temporal trends in exposure and consumption patterns. However, knowledge gaps remain in identifying and validating suitable de facto population biomarkers (PBs) for refinement of WBE back-estimations.

Procedural Dimensions of Religious Exemptions to Covid-19 Vaccine Mandates: Promoting Clarity, Fairness, and Transparency in Applications.

This study examines the procedural ethical considerations surrounding religious exemptions to Covid vaccine mandates, specifically focusing on immigrant healthcare personnel (HCP) and HCPs of color. It emphasizes communication issues with applicants by investigating exemption applications and their accompanying guidelines. While there is extensive literature on the ethical implications of religious exemptions, a notable gap remains in addressing the procedural aspects of religious exemption applications and their reviewing processes.

Normative Values for the Head Shake Sensory Organization Test in an Active Duty Military Cohort.

Introduction: The Head Shake Sensory Organization Test (HS-SOT) assesses postural stability while the head is moving and may also identify deficits in attention associated with the dual task conditions of moving the head at a specified speed while maintaining balance. Normative values for the HS-SOT have not been established in a healthy military population or other highly trained populations such as athletes. Establishing normative values in a military population will enable clinicians to compare the scores of patients with medical conditions that affect postural stability and sensory integration such as concussion or traumatic brain injury, vestibular dysfunction, or migraine to those of a healthy population to determine a need for intervention and for return to duty considerations.

Making waves: Wastewater-based surveillance of cannabis use.

Monitoring cannabis consumption holds great interest due to the increasing trend towards its legalization for both medicinal and recreational purposes, despite the potential risks and harms involved. Wastewater-based surveillance (WBS) offers a valuable tool for assessing shifts and patterns in drug consumption and to evaluate law enforcement strategies and harm reduction programs. However, WBS-derived cannabis use estimates have been linked to greater uncertainties compared to other drugs, in part due to the many different routes of administration and a substantial excretion of metabolites in faecal matter.

Incorporating recirculation effects into metrics of feeding performance for current-feeding zooplankton.

The feeding performance of zooplankton influences their evolution and can explain their behaviour. A commonly used metric for feeding performance is the volume of fluid that flows through a filtering surface and is scanned for food. Here, we show that such a metric may give incorrect results for organisms that produce recirculatory flows, so that fluid flowing through the filter may have been already filtered of food.

Workflow to facilitate the detection of new psychoactive substances and drugs of abuse in influent urban wastewater.

The complexity around the dynamic markets for new psychoactive substances (NPS) forces researchers to develop and apply innovative analytical strategies to detect and identify them in influent urban wastewater. In this work a comprehensive suspect screening workflow following liquid chromatography - high resolution mass spectrometry analysis was established utilising the open-source InSpectra data processing platform and the HighResNPS library. In total, 278 urban influent wastewater samples from 47 sites in 16 countries were collected to investigate the presence of NPS and other drugs of abuse.

Macroscopic Biaxial Order in Multilayer Films of Bent-Core Liquid Crystals Deposited by Combined Langmuir-Blodgett/Langmuir-Schaefer Technique.

Bent-core liquid crystals, a class of mesogenic compounds with non-linear molecular structures, are well known for their unconventional mesophases, characterized by complex molecular (and supramolecular) ordering and often featuring biaxial and polar properties. In the nematic phase, their unique behavior is manifested in the formation of nano-sized biaxial clusters of layered molecules (cybotactic groups). While this prompted their consideration in the quest for nematic biaxiality, experimental evidence indicates that the cybotactic order is only short-ranged and that the nematic phase is macroscopically uniaxial.

The reproductive microbiome and maternal transmission of microbiota via eggs in Sceloporus virgatus.

Maternal transmission of microbes occurs across the animal kingdom and is vital for offspring development and long-term health. The mechanisms of this transfer are most well-studied in humans and other mammals but are less well-understood in egg-laying animals, especially those with no parental care. Here, we investigate the transfer of maternal microbes in the oviparous phrynosomatid lizard, Sceloporus virgatus.

Inter- and intrapopulation resource use variation of marine subsidized western fence lizards.

Marine resource subsidies alter consumer dynamics of recipient populations in coastal systems. The response to these subsidies by generalist consumers is often not uniform, creating inter- and intrapopulation diet variation and niche diversification that may be intensified across heterogeneous landscapes. We sampled western fence lizards, Sceloporus occidentalis, from Puget Sound beaches and coastal and inland forest habitats, in addition to the lizards' marine and terrestrial prey items to quantify marine and terrestrial resource use with stable isotope analysis and mixing models.

Young Adult Caregiving Daughters and Diagnosed Mothers Navigating Breast Cancer Together: Open and Avoidant Communication and Psychosocial Outcomes.

For many diagnosed mothers and their daughters, breast cancer is a shared experience. However, they struggle to talk about cancer. This is particularly true when the daughter is in adolescence or young adulthood, as they tend to be more avoidant, which is associated with poorer biopsychosocial outcomes.

The effect of heat on lung diffusing capacity for carbon monoxide (DLCO) during cycling exercise.

Purpose: This study aimed to quantify the combined effects of heat exposure and exercise of increasing intensity on pulmonary blood flow using lung diffusing capacity for carbon monoxide (DLCO) as an indirect measure. We hypothesized that, during exercise in the heat, the well-documented increase in skin blood flow for thermoregulation would lead to alterations in pulmonary blood flow and a subsequent fall in DLCO versus a thermoneutral condition.

Methods: Nine healthy subjects (4 F/5 M, 20-45 years, VOmax 46.
