Starch Gelatinization as Affected by Lipid
Gelatinization of untreated and defatted corn starch as affected by added elaidinized and non-elaidinized olive oil was investigated. The experimental plan was a 2 x 3 factorial, which included no added lipid as well as elaidinized and non-elaidinized olive oil. The added lipids were used at the level of 6 mg per gram of starch in pastes containing 8 g of starch per 100 ml of liquid. Seven replications were completed. Suspensions were heated in the Brabender Amylograph from 25°C to 92.5°C (45 min) and held at 92.5°C for 15 min. Data taken from each amylogram included: the transition temperature, the temperature of maximum viscosity, viscosity after 45 min of heating and terminal viscosity. Photomicrographs were made of samples of each paste taken before heating and at several stages during heating. Pastes were poured while hot into custard cups and held at room temperature for 24 hr. Penetrability measurements were made on the gels. Viscosity and penetrability data, as well as transition temperature, were subjected to analysis of variance.
Defatting the corn starch resulted in reduced transition temperature (P \u3c 0.01), reduced maximum viscosity (P \u3c 0.01), essentially unaffected terminal viscosity and increased gel strength (P \u3c 0.01). The photomicrographs indicate that possibly the granules of defatted starch swelled more freely and rapidly and showed more implosion that the granules of untreated starch. The greater implosion could explain both lower maximum viscosity and higher gel strength of samples containing defatted starch. The effect of added lipid was limited to increased gel strength and only in the case of untreated starch. The photomicrographs show a possible protective effect of lipid on the granules so that in the presence of lipid, granules were permitted to implode sufficiently but not too extensively and fragmentation did not occur during the holding period. The interaction between starch treatment and lipid was significant (P \u3c 0.01). No clear-cut differences were found between elaidinized and non-elaidinized lipid. Possibly future work should involve the addition of higher concentrations of lipid than used in this study
Emergency preparedness for those who care for infants in developed country contexts
Emergency management organisations recognise the vulnerability of infants in emergencies, even in developed countries. However, thus far, those who care for infants have not been provided with detailed information on what emergency preparedness entails. Emergency management authorities should provide those who care for infants with accurate and detailed information on the supplies necessary to care for them in an emergency, distinguishing between the needs of breastfed infants and the needs of formula fed infants. Those who care for formula fed infants should be provided with detailed information on the supplies necessary for an emergency preparedness kit and with information on how to prepare formula feeds in an emergency. An emergency preparedness kit for exclusively breastfed infants should include 100 nappies and 200 nappy wipes. The contents of an emergency preparedness for formula fed infants will vary depending upon whether ready-to-use liquid infant formula or powdered infant formula is used. If ready-to-use liquid infant formula is used, an emergency kit should include: 56 serves of ready-to-use liquid infant formula, 84 L water, storage container, metal knife, small bowl, 56 feeding bottles and teats/cups, 56 zip-lock plastic bags, 220 paper towels, detergent, 120 antiseptic wipes, 100 nappies and 200 nappy wipes. If powdered infant formula is used, an emergency preparedness kit should include: two 900 g tins powdered infant formula, 170 L drinking water, storage container, large cooking pot with lid, kettle, gas stove, box of matches/lighter, 14 kg liquid petroleum gas, measuring container, metal knife, metal tongs, feeding cup, 300 large sheets paper towel, detergent, 100 nappies and 200 nappy wipes. Great care with regards hygiene should be taken in the preparation of formula feeds. Child protection organisations should ensure that foster carers responsible for infants have the resources necessary to formula feed in the event of an emergency. Exclusive and continued breastfeeding should be promoted as an emergency preparedness activity by emergency management organisations as well as health authorities. The greater the proportion of infants exclusively breastfed when an emergency occurs, the more resilient the community, and the easier it will be to provide effective aid to the caregivers of formula fed infants
Toddler milk advertising in Australia: the infant formula ads we have when we donât have infant formula ads
The Marketing in Australia of Infant Formula: Manufacturersâ and Importersâ Agreement (MAIF) prevents manufacturers and importers from advertising infant formula. However, toddler milks, which share brand identities with infant formula, are advertised freely; and recent research suggests consumers fail to distinguish between advertising for infant formula and for toddler milk. This study examined whether Australian parents recalled having seen advertisements for âformulaâ. Most respondents (66.8%) reported seeing an advertisement for infant formula, with those who had only seen non-retail advertising more than twice as likely to believe that they had seen such an advertisement as those who had only seen retail advertising. This suggests that toddler milk advertisements are functioning as defacto infant formula advertisements in Australia. Thus the MAIF is failing to achieve its stated purpose

On computer vision in wireless sensor networks.
Wireless sensor networks allow detailed sensing of otherwise unknown and inaccessible environments. While it would be beneficial to include cameras in a wireless sensor network because images are so rich in information, the power cost of transmitting an image across the wireless network can dramatically shorten the lifespan of the sensor nodes. This paper describe a new paradigm for the incorporation of imaging into wireless networks. Rather than focusing on transmitting images across the network, we show how an image can be processed locally for key features using simple detectors. Contrasted with traditional event detection systems that trigger an image capture, this enables a new class of sensors which uses a low power imaging sensor to detect a variety of visual cues. Sharing these features among relevant nodes cues specific actions to better provide information about the environment. We report on various existing techniques developed for traditional computer vision research which can aid in this work
The impact of diet during adolescence on the neonatal health of offspring:evidence on the importance of preconception diet. The HUNT study
Emerging evidence suggests that parentsâ nutritional status before and at the time of conception influences the lifelong physical and mental health of their child. Yet little is known about the relationship between diet in adolescence and the health of the next generation at birth. This study examined data from Norwegian cohorts to assess the relationship between dietary patterns in adolescence and neonatal outcomes. Data from adolescents who participated in the Nord-Trøndelag Health Study (Young-HUNT) were merged with birth data for their offspring through the Medical Birth Registry of Norway. Young-HUNT1 collected data from 8980 adolescents between 1995 and 1997. Linear regression was used to assess associations between adolescentsâ diet and later neonatal outcomes of their offspring adjusting for sociodemographic factors. Analyses were replicated with data from the Young-HUNT3 cohort (dietary data collected from 2006 to 2008) and combined with Young-HUNT1 for pooled analyses. In Young-HUNT1, there was evidence of associations between dietary choices, meal patterns, and neonatal outcomes, these were similar in the pooled analyses but were attenuated to the point of nonsignificance in the smaller Young-HUNT3 cohort. Overall, energy-dense food products were associated with a small detrimental impact on some neonatal outcomes, whereas healthier food choices appeared protective. Our study suggests that there are causal links between consumption of healthy and unhealthy food and meal patterns in adolescence with neonatal outcomes for offspring some years later. The effects seen are small and will require even larger studies with more state-of-the-art dietary assessment to estimate these robustly

Adaptive awareness for personal and small group decision making.
Many situations call for the use of sensors monitoring physiological and environmental data. In order to use the large amounts of sensor data to affect decision making, we are coupling heterogeneous sensors with small, light-weight processors, other powerful computers, wireless communications, and embedded intelligent software. The result is an adaptive awareness and warning tool, which provides both situation awareness and personal awareness to individuals and teams. Central to this tool is a sensor-independent architecture, which combines both software agents and a reusable core software framework that manages the available hardware resources and provides services to the agents. Agents can recognize cues from the data, warn humans about situations, and act as decision-making aids. Within the agents, self-organizing maps (SOMs) are used to process physiological data in order to provide personal awareness. We have employed a novel clustering algorithm to train the SOM to discern individual body states and activities. This awareness tool has broad applicability to emergency teams, military squads, military medics, individual exercise and fitness monitoring, health monitoring for sick and elderly persons, and environmental monitoring in public places. This report discusses our hardware decisions, software framework, and a pilot awareness tool, which has been developed at Sandia National Laboratories
Healthcare Staff Perceptions Following Inoculation with the BNT162b2 mRNA COVID-19 Vaccine at University Hospitals Coventry Warwickshire NHS Trust
Background: COVID-19 vaccination programmes offer hope for a potential end to the acute phase of the COVID-19 pandemic. We present perceptions following from a cohort of healthcare staff at the UK NHS hospital, which first initiated the BNT162b2 mRNA COVID-19 (âPfizerâ) vaccination program. Methods: A paper-based survey regarding perceptions on the BNT162b2 mRNA COVID-19 vaccine was distributed to all healthcare workers at the University Hospitals Coventry Warwickshire NHS Trust following receipt of the first vaccine dose. Results: 535 healthcare workers completed the survey, with a 40.9% response rate. Staff felt privileged to receive a COVID-19 vaccine. Staff reported that they had minimised contact with patients with confirmed or suspected COVID-19. Reported changes to activity following vaccination both at work and outside work were guarded. Statistically significant differences were noted between information sources used by staff groups and between groups of different ethnic backgrounds to inform decisions to receive vaccination. Conclusions: NHS staff felt privileged to receive the COVID-19 vaccine, and felt that their actions would promote uptake in the wider population. Concerns regarding risks and side effects existed, but were minimal. This research can be used to help inform strategies driving wider vaccine uptake amongst healthcare staff and the public
Demand-side management by electric utilities in Switzerland: Analyzing its impact on residential electricity demand
In this paper we use panel data from a survey conducted on 30 utilities in Switzerland to estimate the impact of demand-side management (DSM) activity on residential electricity demand. Using the variation in DSM activity within utilities and across utilities over time we identify the impact of DSM programs and find that their presence reduces per customer residential electricity consumption by around 5%. If we consider monetary spending, the effect of a 10% increase in DSM spending causes a 0.14% reduction in per customer residential electricity consumption. The cost of saving a kilowatt hour is around 0.04 CHF while the average cost of producing and distributing electricity in Switzerland is around 0.18 CHF per kilowatt hour. We conclude that current DSM practices in Switzerland have a statistically significant effect on reducing the demand for residential electricity
