A Smart Box for Blood Bags Transport: Simulation Model of the Cooling Autonomy Control System

A R T I C L E I N F O A B S T R A C T Article history: Received: 14 November, 2019 Accepted: 08 January, 2020 Online: 27 January, 2020 This paper faces the topic of blood products transport by applying simulation, control and data exchange technologies in order to implement a safe and efficient integrated transportation system. As known, the bio-chemical properties of blood and its derivatives are subjected to deterioration whenever a well determined temperature range is not respected for an excessive time interval. At present, blood products are mainly transported in thermally insulated boxes filled with ice which, other than ensuring a limited time of the material survival, are not able to allow any type of control over the state of the material and the history of temperature variations occurred within the storage volume. The innovative proposal discussed in this paper regards a smart box for blood transport, equipped with a system for temperature control which uses elements of eutectic material stored in a separated compartment; eutectic exchanges heat with the transported blood bags through a separation wall on which blowers are installed for cold air circulation. The air flow is activated as soon as the box internal temperature increases over a pre-defined threshold, to extend as much as possible the eutectic material duration. The smart box is equipped with sensors that dialogue by cloud with a central server on which is installed a Matlab-Simulink dynamic simulator of the box thermodynamic behavior, main object of the present paper. In particular, the simulator here presented has been improved by advanced heat exchange correlations and a more realistic system of thermal balance equations. The simulator allows to monitor the time remaining to the exhaustion of the cooling effect. In case of lack of autonomy, a logistic algorithm provides the coordinates of the nearest healthcare location for safe storage.
The Verbal Tone in Mandatory Environmental Disclosures: Evidence from Changes in Disclosures Following SEC Guidance

ABSTRACT This study investigates whether the verbal tone of environmental disclosures in companies’ annual reports changed following SEC interpretive guidance released in 2010. The content analysis software DICTION is used to construct measures of verbal tone and size of the disclosures. For a sample of companies in both environmentally sensitive and non-sensitive industries, we find an increase in the degree of ‘realism’ and ‘certainty’ of the disclosures following the release of the SEC guidance. The results hold after controlling for environmental performance and firm specific characteristics. In addition, the size of environmental disclosures increased in the year preceding the release of the guidance, suggesting that companies may have anticipated an interpretive release from the SEC. Furthermore, there were no significant changes in the size and verbal tone of voluntary environmental disclosures over the same time period, suggesting that the changes in the annual reports filed with the SEC resulted primarily from companies’ responses to the interpretive guidance. These findings show that impressions management is less prevalent in mandated environmental disclosures.
Don’t stop believin’: the journey to entrepreneurial burnout and back again

Abstract Burnout is a well-studied phenomenon that can cause deleterious effects to any organization, especially if the organization is a recent startup. It has been suggested that burnout is often prevented by psychological capital and/or passion, both of which entrepreneurs seem to have in abundance. However, recent attention has been directed toward entrepreneurial burnout, a phenomenon that occurs when an entrepreneur is overcome with stress and considers throwing in the towel. Grounded theory-building techniques are used to analyze data from a new venture with a first-time entrepreneur. Data includes 15 months of financial reports, sales reports, observations, social media posts/reviews and interview data. A chronic lack of resources, high expectations, and a loss of hope potentially lead to powerful negative emotions such as burnout. More than other psychological capital components, hope seemed to be the key contributor to a downward spiral and to a renewal of passion and energy. This research is unique for a few reasons. First, it singles out the power of hope in the burnout literature. Second, the researchers had the opportunity to have incredible access during their 15-month data gathering. Third, the researchers were able to witness an entrepreneur in both a downward (negative) and upward (positive) cycle.
Graphene Oxide Reinforcing Genipin Crosslinked Chitosan-Gelatin Blend Films

This study was targeted towards the synthesis and characterization of new chitosan–gelatin biocomposite films reinforced with graphene oxide and crosslinked with genipin. The composites’ mode of structuration was characterized by Fourier Transform Infrared spectroscopy and X-ray diffraction, while morphology and topography were investigated by scanning electron microscopy, nano-computer tomography and profilometry. Eventually, thermal stability was evaluated through thermogravimetrical analysis, mechanical properties assessment was carried out to detect potential improvements as a result of graphene oxide (GO) addition and in vitro enzyme degradation was performed to discern the most promising formulations for the maturation of the study towards in vivo assays. In accordance with similar works, results indicated the possibility of using GO as an agent for adjusting films’ roughness, chemical stability and polymer structuration. The enzymatic stability of chitosan–gelatin (CHT-GEL) films was also improved by genipin (GEN) crosslinking and GO supplementation, with the best results being obtained for CHT-GEL-GEN and CHT-GEL-GEN-GO3 (crosslinked formulation with 3 wt.% GO). Yet, contrary to previous reports, no great enhancement of CHT-GEN-GEL-GO thermal performances was obtained by the incorporation of GO.
T wave and QT interval in the Standardbred horse: A descriptive study

T wave and QT interval in the standardbred horse: A descriptive study Erin E. Preiss Advisors: University of Guelph, 2016 Dr. Peter Physick-Sheard & Dr. W.J. Brad Hanna The human T wave and QT interval are well characterized. As long and short QT interval and QT interval dispersion are associated with arrhythmias and sudden death, influential factors, methods of measurement and heart rate (HR) correction are numerous. In horses, significance has been attached to QRS duration, T morphology, and QT interval, but clinical associations are not well supported and measurement not standardized. This study used holter monitoring of clinically normal Standardbred horses at rest and during exercise to develop an automated algorithm for measurement of T characteristics and QT interval. The algorithm was tested on 545 ECG segments of 12 successive RR intervals and successfully identified 97.0% of key waveform points. QT onset and offset were reliably identified 99.8% and 94.5% of the time respectively. While longitudinal studies will be required, this algorithm should aid in establishing normal equine QT intervals and accurate HR correction methods.
VARIATIONS IN THE ARTERIAL BRANCHING PATTERN OF THE COELIAC TRUNK : A CADAVERIC STUDY

The knowledge of the anomalous arterial branching patterns is essential from the view point of surgical anatomy, especially while contemplating hepatic and pancreatic surgeries. The anatomical variations of the celiac trunk, superior mesenteric artery, renal and gonadal arteries are well established. The presence of anomalous origin of the inferior phrenic artery from the celiac trunk is comparatively rare in available literature but is clinically very important because this may act as a major source of collateral or parasitized arterial supply to hepato-cellular carcinoma, second only to the hepatic artery. The present study was carried out from the data collected over a period of four years when routine dissection was done while teaching the first year MBBS undergraduate students. The arterial branching pattern of the coeliaco-mesenteric axis was noted down from a total of 40 cadavers (10 each year) and any anomalous pattern observed was documented. In our study we observed a lower origin of the celiac trunk through the substance of the pancreas in 3 cases, presence of two separate trunks namely gastro-splenic and hepato-mesenteric arising from the abdominal aorta in 4 cases and both inferior phrenic arteries arising from celiac trunk in 1 case. The remaining 32 cadavers had normal arterial branching pattern. These anomalies could cause a catastrophe during surgical procedures, especially laparoscopic ones if the same is not kept in mind before contemplating preoperative investigations. The awareness of these vascular anomalies is very important while contemplating radiological and surgical interventions. Therefore keeping in mind the immense radiological and surgical importance of these variations, the continuous reporting of such cases is significant.

Investigation of the Adult Vaccination Status and Influencing Factors in People Aged 65 Years and Over Registered in A Family Health Center in Mersin City

Today, modernization of life has increased the life span of people, consequently increasing the elderly population in the world. The World Health Organization (WHO) estimates that between the years 2015 and 2050, the world’s population aged more than 60 years will almost double from 12% to 22%; in other words, the 60-year-old population that was 900 million in 2015 would have reached 2 billion by the year 2050 and 80% of the elderly population will be living in lowor average-income countries (1). The aging phenomenon, which is more evident in developed countries, is now gaining importance also in developing countries, and the elderly population is gradually increasing in Turkey as well (2).
Momentum Turning Points

Turning points are the Achilles' heel of time-series momentum portfolios. Slow signals fail to react quickly to changes in trend while fast signals are often false alarms. We examine theoretically and empirically how momentum portfolios of various intermediate speeds, formed by blending slow and fast strategies, cope with turning points. Our model predicts an optimal dynamic speed selection strategy. We apply this strategy across domestic and international equity markets and document efficient out-of-sample performance. We also propose a novel decomposition of momentum strategy alpha, highlighting the role of volatility timing.
Clinical benefits of vitamin A supplementation in infants and children with severe pneumonia

Background About 190 million preschool children living in developing countries are at risk of vitamin A deficiency. Vitamin A deficiency and acute respiratory tract infection (ARI) are public health problems in developing countries. Children with vitamin A deficiency are more susceptible to measles, respiratory tract infection, and other infections. Some studies show that vitamin A supplements may reduce the severity of respiratory tract infection and other systemic complications of measles, and diarrhea. Objective To evaluate the effect of vitamin A supplementation in infants and children with severe pneumonia. Methods The study was a randomized trial on children with severe pneumonia. Participants were randomly assigned to either receive vitamin A in addition to standard treatment (Group A), or standard treatment alone (Group C). Time to achieve the normal respiratory rate, time to achieve disappearance of subcostal retractions and fine rales were compared between the 2 groups. Result There was no significant difference in the achievement of normal respiratory rate between the vitamin group and the control group (3.08 days vs 3.29 days). There was also no significant difference in the disappearance of subcostal retractions among the two groups (2.30 days vs 2.48 days). However, there was significant difference in the disappearance of fine rales between the two groups. The disappearance of fine rales in the vitamin A group occurred earlier (mean 3.72 days) than in the control group (mean 4.04 days) (P<0.01). Conclusions This study indicates that no significant difference in the achievement of normal respiratory rate and disappearance of subcostal retractions between the vitamin A group as compared to the control group, but there was a significant difference in the disappearance of fine rales between two groups.
Substance Abuse Among Health Professionals: A Personal Construct Analysis

Abstract This study aims to describe health professionals who abuse substances in terms of their personal construing process and other associated psychological measures. Thirty health professionals hospitalized because of a substance use disorder in a specialized clinic were recruited for this study. In the same way as in previous studies carried out in clinical populations, more than half of the participants presented cognitive conflicts (in the form of implicative dilemmas) and this group scored higher on trait anxiety and burnout than health professionals without such conflicts. No statistically significant differences were found between those with implicative dilemmas and those without in terms of depression symptoms or state of anxiety. A logistic regression showed that the presence of cognitive conflicts was best predicted by burnout. Distance between ideal and actual self and cognitive complexity were the best predictors of belonging to our clinical sample or to a randomly matched community sample. Content analysis of the constructs revealed an overrepresentation of values and interests in the clinical sample. The findings are discussed in relation to previous research in substance use, cognitive conflicts in the clinical population and identity construction.
Signals of recent tropical radiations in Cunoniaceae, an iconic family for understanding Southern Hemisphere biogeography

Extratropical angiosperm diversity is thought to have arisen from lineages that originated in the more diverse tropics, but studies of dispersal between tropical and extratropical environments and their consequences for diversification are rare. In order to understand the evolutionary effects of shifts between the tropics and extratropics, defined here as areas that do versus do not regularly experience freezing temperatures, we studied the biogeographic history and associated diversification patterns of Cunoniaceae. We mapped the distribution of all species in the family and combined this with a newly constructed phylogeny for the family. The family shows a long evolutionary association with both tropical and extratropical environments, the tropics house considerably greater species richness of Cunoniaceae. Indeed, both tropical and extratropical environments appear to have had a similar number of lineages until 12 Ma, after which time the number of lineages in tropical areas increased at a faster rate. In addition, community phylogenetic approaches show that tropical regions have markedly less phylogenetic diversity than expected given their species richness, which is further suggestive of recent species radiations in tropical areas. The Cunoniaceae show an atypical pattern for angiosperms of frequent shifts between tropical and extratropical environments, but despite this, shows a more conventional pattern of higher, although recent, diversification rates in the tropics. Our results support the idea that high angiosperm species richness in the tropics may result from the tropics acting as a cradle of recent angiosperm diversification.
Molecular-level kinetic modeling of the upgrading of residual oil in supercritical water

The objective of this thesis is to develop a molecular-level kinetic model for the upgrading of residual oil in an environment of supercritical water. The Kinetic Modeler’s Toolbox software, developed by the Klein research group, is used to make this kinetic model. A rank zero reaction network is created. This is necessary to limit the number of model compounds. The reaction network contains four major chemical pathways: pyrolysis, hydrolysis, aromatization and coking. The entire network consists of 10025 reactions between 2894 components. Besides creating a reaction network, formats for the rate laws are constructed. Because the system is in a pseudo single phase and no catalyst is used, the underlying principle for the rate laws is microkinetics. Supercritical water has three different solvent effects: solvent cage effect, the effect of the dielectric constant and the water-oil phase behavior. These solvent effects are incorporated into the rate laws. Due to the unavailability of product data for supercritical water upgrading of residual oil in literature, tuning of the kinetic parameters is not done in this thesis. Instead, two molecular representations of feed streams are made. One of them is a molecular representation of residual oil. This is done in order to show that the chosen model compounds can model a residual oil feed stream. The other is a molecular representation of VGO. VGO is a subset of residual oil, that contains the more volatile compounds. For VGO a product data set for supercritical water upgrading is available in literature. Kinetic parameters are tuned, such that the simulated properties of the output of the kinetic model are close to those reported in literature. This is done in order to show that the reactions, in the reaction network, and the format of the rate laws represent the physical and chemical phenomena that occur in supercritical water upgrading of oil fractions.
‘I want to read it in my hands’: The aesthetic attraction of independent women’s magazines

There is a growing body of evidence suggesting that independent magazines, also known as ‘independents’, are thriving in Australia’s print media industry. As ‘maverick’ editors, owners and publishers focus more on the design and aesthetic aspects of their publications in response to changing reader expectations, there appears to be a demand for independents among female readers. In particular, young adult female readers are choosing to engage with independent women’s magazines in Australia, placing particular emphasis on the aesthetic reading experience offered by the hard-copy format. To explore this phenomenon, a survey and focus group were conducted among women aged 18‐24 years, using Blumler and Katz’s Uses and Gratifications theory as the theoretical framework. The initial survey garnered findings from 300 respondents, while the focus group consisted of six participants. One key aspect of the results is that aesthetics is central to understanding the continued appeal and use of such a medium. Other aspects include quality of content, entertainment, escape, collection and habit, and ease of use. In an age where ‘digital’ is often regarded as the norm, young adult female readers are seeking inspiration and expression from independent women’s magazines.

Educated and Engaged Communicators Are Critical to Successful Integrated Pest Management Adoption

Integrated pest management (IPM) programs combining multiple compatible pest control tactics can result in effective commodity protection, pesticide use reduction, and cost savings – yet establishment of IPM programs is still low in many areas of the United States. While several potential causes of and solutions to low adoption rates exist, our focus is on the often-neglected human aspect of IPM. IPM educators who serve as the conduit of IPM research and advice to IPM practitioners often face challenges in areas that are less scientific and more social, such as communication and teaching. The skills needed in these areas (e.g., conflict management and resolution, needs assessment, negotiation, training, and informal education) are sometimes neglected in the professional development of future IPM educators, to the detriment of their ability to work with practitioners to encourage adoption of IPM programs. We explore these challenges, including a survey of current IPM educators, and propose areas of communication skills that could be included in the professional development of future or early-career IPM educators.
