No full textOral History Interview with MJ Cotter, December 6, 2001
No full textThe National Museum of the Pacific War presents an interview with M J Cotter. Cotter joined the Navy in March of 1941. After boot camp, he provided upkeep and maintenance of the 16-inch gun turret aboard the USS Maryland (BB-46). They traveled to Hawaii around July of 1941. The Maryland was present on Battleship Row during the attack on Pearl Harbor. Cotter was aboard the ship and describes his experiences through this fateful day, including their 50-caliber gunner taking down a Japanese plane. After repairs to their ship, they participated in the battles of Midway, Tarawa, Guam, Saipan, Tinian, Leyte Gulf and Okinawa. Cotter was discharged in July of 1946
Preterm birth during the COVID‐19 pandemic: parental experience
No full textThe pandemic arising from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) known as COVID-19 has had wide reaching primary and secondary health implications.1 At the end of March 2020, in order to slow the rate of infection, the United Kingdom (UK) government implemented a strict lockdown including; the closure of schools, workplaces and restrictions on outdoor movements other than for exercise or essential shopping, which lasted until early June 2020. During this period, the National Health Service (NHS) experienced cessation of many services, whilst others imposed changes to reduce visitors and footfall on hospital sites. This included stringent and restrictive measures as to how women gave birth in addition to how Neonatal Services operated. In April 2020, the British Society of Perinatal Medicine published extensive guidance on reducing the transmission and spread of COVID-19 amongst families and their newborns.2 As a result, all non-essential maternity care stopped, with in-person appointments changed to telephone or video consultations. Strict social distancing measures were implemented by units around the country by limiting partners of women to attend births (with many women giving birth alone except from the care of healthcare professionals), as well as reducing parental access to infants, particularly those born preterm or unwell, with only one parent at a time allowed by the cot side and no additional visits from the immediate or extended family. The aim of this study was to explore the experiences, information and support needs and decision making of parents with a preterm or unwell neonate during the COVID-19 pandemic

Thermal properties of big bluestem as affected by ecotype and planting location along the precipitation gradient of the Great Plains.
No full textThe objective of this research was to study the effect of ecotype and planting location on thermal properties of big bluestem. Three big bluestem ecotypes (CKS, EKS, ILL) and a cultivar (KAW) were harvested in 2010 from four locations (Colby, Hays, and Manhattan, KS; and Carbondale, IL) and were evaluated for their specific heat, thermal conductivity, thermal stability, HHV (high heating value), and proximate contents. All populations revealed a large variation in specific heat (2.35-2.62 kJ/kg/K), thermal conductivity (77.85-99.06 x 10³ W/m/K), thermogravimetric analysis as weight loss during the
heating process (71-73%), and HHV (17.64-18.67 MJ/kg). Specific heat of the big bluestem was significantly affected by planting location, ecotype, and interaction between location and ecotype. Planting location had stronger influence on specific heat than ecotype. Specific heat increased as temperature increased, and a linear correlation model for specific heat prediction was developed as a function of temperature. Ecotype, planting location, and the interaction of ecotype and planting location did not have a significant effect on thermal conductivity; however, density and particle size showed a completely opposite relationship on thermal conductivity. Both planting location and ecotype significantly affected HHV. Among all environmental factors, potential evapotranspiration had the most significant effect on thermal properties
The evolution of social orienting: evidence from chicks (Gallus gallus) and human newborns
No full textBackground
Converging evidence from different species indicates that some newborn vertebrates, including humans, have visual predispositions to attend to the head region of animate creatures. It has been claimed that newborn preferences for faces are domain-relevant and similar in different species. One of the most common criticisms of the work supporting domain-relevant face biases in human newborns is that in most studies they already have several hours of visual experience when tested. This issue can be addressed by testing newly hatched face-naïve chicks (Gallus gallus) whose preferences can be assessed prior to any other visual experience with faces.
Methods
In the present study, for the first time, we test the prediction that both newly hatched chicks and human newborns will demonstrate similar preferences for face stimuli over spatial frequency matched structured noise. Chicks and babies were tested using identical stimuli for the two species. Chicks underwent a spontaneous preference task, in which they have to approach one of two stimuli simultaneously presented at the ends of a runway. Human newborns participated in a preferential looking task.
Results and Significance
We observed a significant preference for orienting toward the face stimulus in both species. Further, human newborns spent more time looking at the face stimulus, and chicks preferentially approached and stood near the face-stimulus. These results confirm the view that widely diverging vertebrates possess similar domain-relevant biases toward faces shortly after hatching or birth and provide a behavioural basis for a comparison with neuroimaging studies using similar stimuli
Uncovering microbial populations in the lumen of neonatal enteral feeding tubes utilising 16s rRNA sequencing
No full textGastrointestinal microbiome is increasingly implicated in the morbidity associated with being born preterm. Enteral tubes (ET) are essential for the nutritional care of preterm infants. Limited culture-based studies have suggested they are colonised by high densities of microorganisms. Microbial DNA was extracted from 60 ETs retrieved from infants in a tertiary neonatal unit and analysed by16s rRNA sequencing of the V4 variable region. Relative abundance analysis on dominant microorganisms demonstrated that compared to breast milk, formula significantly increased abundance of Streptococcus spp and significantly decreased Enterococcus spp and Enterobacteriaceae Vaginal birth was also associated with significantly increased relative abundance of Streptococcus . This study more accurately demonstrates the extent of microbial diversity in neonatal ETs, with feeding regime significantly influencing colonisation patterns. Colonisation with unwanted organisms, as a result of specific care regimes, could result in disruption of the fragile infant gut microbiome, with implications for long-term morbidity
