Prevalence of food insecurity and satisfaction with on-campus food choices among Australian university students

Purpose: Food insecurity and poor access to healthy food is known to compromise tertiary studies in university students, and food choices are linked to student perceptions of the campus food environment. This study aims to describe the prevalence, demographic and education characteristics associated with food insecurity in a sample of Australian university students, and their satisfaction with on-campus food choices. Design/methodology/approach: An online, cross-sectional survey conducted as part of the biannual sustainability themed survey was conducted at the University of Tasmania in March 2020. A single-item measure was used to assess food insecurity in addition to six demographic and education characteristics, and four questions about the availability of food, affordable food, sustainable food and local food on campus. Findings: Survey data (n=1,858) were analysed using bivariate analyses and multivariate binary logistic regression. Thirty-eight percent of respondents (70% female; 80% domestic student; 42% aged 18-24 years) were food insecure. Overall, 41% of students were satisfied with the food available on campus. Nearly half (47%) of food insecure students were dissatisfied or very dissatisfied with the availability of affordable food on campus. A minority of students were satisfied with the availability of sustainable food (37%) and local food (33%) on campus. Originality: These findings demonstrate a high prevalence of food insecurity and deficits in the university food environment, which can inform the development of strategies to improve the food available on campus, including affordable, sustainable, and local options.
Fluoroethylene Carbonate Additives to Render Uniform Li Deposits in Lithium Metal Batteries

Lithium (Li) metal has been considered as an important substitute for the graphite anode to further boost the energy density of Li‐ion batteries. However, Li dendrite growth during Li plating/stripping causes safety concern and poor lifespan of Li metal batteries (LMB). Herein, fluoroethylene carbonate (FEC) additives are used to form a LiF‐rich solid electrolyte interphase (SEI). The FEC‐induced SEI layer is compact and stable, and thus beneficial to obtain a uniform morphology of Li deposits. This uniform and dendrite‐free morphology renders a significantly improved Coulombic efficiency of 98% within 100 cycles in a Li | Cu half‐cell. When the FEC‐protected Li metal anode matches a high‐loading LiNi0.5Co0. 2Mn0.3O2 (NMC) cathode (12 mg cm−2), a high initial capacity of 154 mAh g−1 (1.9 mAh cm−2) at 180.0 mA g−1 is obtained. This LMB with conversion‐type Li metal anode and intercalation‐type NMC cathode affords an emerging energy storage system to probe the energy chemistry of Li metal protection and demonstrates the material engineering of batteries with very high energy density.
Assessment of fibrinogen level among Sudanese patient with myocardial infarction in Khartoum City- Sudan

Fibrinogen has been identified as a major independent risk factor for cardiovascular diseases. Myocardial infarction is cardiomyocyte death as result of a prolonged ischemia. The aim of this study was to determine fibrinogen level in Sudanese patients with myocardial infarction. A case control study was conducted in AL-Shaab Hospital and Sudan heart center at Khartoum state, Sudan. A total of 100 study participants were enrolled in the study; 50 were myocardial infarction patients and 50 were apparently healthy individuals as control. The blood Samples were collected in 3.2 % trisodium citrate and Fibrinogen level was measured using ready kits principle. The data were analysed by statistical package of social sciences version 21. The study revealed that fibrinogen level was higher in Myocardial infarction (MI) patients compared with normal individuals. There is a significant strong positive correlation between fibrinogen and Troponin-1 Level at the 0.05 level.
Beta redundancy for functional ecology

Functional beta redundancy has been recently defined as the fraction of species dissimilarity between two plots not expressed by functional dissimilarity. As such, it summarizes to what degree the compositional differences between two plots mirror their functional differences. A fundamental condition to obtain an appropriate measure of functional beta redundancy is that the functional dissimilarity between the plots is always lower (or at least not higher) than the corresponding species dissimilarity. However, many of the extant measures of functional dissimilarity do not fulfil this requirement. To overcome this problem, a class of tree‐based indices of functional dissimilarity that conform to the above ‘redundancy property’ has been recently proposed. However, functional dissimilarity measures need not necessarily be based on a hierarchical representation of the species functional relationships. In this paper, we introduce an algorithmic index of functional dissimilarity that conforms to the redundancy property. Since it does not rely on a hierarchical species organization, the proposed index allows to calculate functional beta redundancy in a more suitable way to the non‐hierarchical structure of the species functional relationships. The behaviour of the proposed measure is illustrated with data on the species functional turnover along real and simulated ecological gradients.
Vision-Based System for Assisting Blind People to Wander Unknown Environments in a Safe Way

Vision is the principal source of information of the surrounding world. It facilitates our movement and development of everyday activities. In this sense, blind people have great difficulty for moving, especially in unknown environments, which reduces their autonomy and puts them at risk of suffering an accident. Electronic Travel Aids (ETAs) have emerged and provided outstanding navigation assistance for blind people. In this work, we present the methodology followed for implementing a stereo vision-based system that assists blind people to wander unknown environments in a safe way, by sensing the world, segmenting the floor in 3D, fusing local 2D grids considering the camera tracking, creating a global occupancy 2D grid, reacting to close obstacles, and generating vibration patterns with an haptic belt. For segmenting the floor in 3D, we evaluate normal vectors and orientation of the camera obtained from depth and inertial data, respectively. Next, we apply RANSAC for computing efficiently the equation of the supporting plane (floor). The local grids are fused, obtaining a global map with data of free and occupied areas along the whole trajectory. For parallel processing of dense data, we leverage the capacity of the Jetson TX2, achieving high performance, low power consumption, and portability. Finally, we present experimental results obtained with ten (10) participants, in different conditions, with obstacles of different height, hanging obstacles, and dynamic obstacles. These results show high performance and acceptance by the participants, highlighting the easiness to follow instructions and the short period of training.
Analysis of Phytochemistry and Antimicrobial activity of Tridaxprocumbens Linn

The aim of the present study was to investigate the phytochemistry and bioactive nature of Tridax procumbens. The ethanol, benzene and petroleum ether extracts of dried roots of this plant were investigated for phytochemistry and antibacterial analysis. The antibacterial activity was evaluated against different bacterial strains viz. Escherichia coli, Staphylococcus aureus, Salmonella typhii, Klebsiella pneumoniae and Shigella flaxineri by detecting zone of inhibition. The zone of inhibition was compared with standard discs of Gentamicin. From these extracts, two of them (ethanolic and pet-ether extracts) revealed significant results as compared to benzene extract. The qualitative analysis revealed the presence of flavonoids, pholabatannins, resins, tannins, phenols, lipids and fats and carbohydrates.
Morphology, microstructure, and doping behaviour: A comparison between different deposition methods for poly‐Si/SiOx passivating contacts

Crystallographic structures, optoelectronic properties, and nanoscale surface morphologies of ex situ phosphorus‐doped polycrystalline silicon (poly‐Si)/SiOx passivating contacts, formed by different deposition methods (sputtering, plasma‐enhanced chemical vapour deposition [PECVD], and low‐pressure chemical vapour deposition [LPCVD]), are investigated and compared. Across all these deposition technologies, we noted the same trend: higher diffusion temperatures yield films that are more crystalline but that have rougher surface morphologies due to bigger surface crystal grains. Also, the recrystallization process of the as‐deposited Si films starts from the SiOx interface, rather than from the film surface and bulk. However, there are some distinct differences among these technologies. First, the LPCVD method yields the lowest deposition rate, roughest surfaces, and smallest degree of crystallinity on finished poly‐Si films. In contrast, the PECVD method has the highest deposition rate and smoothest surfaces for both as‐deposited Si and annealed poly‐Si films. Second, as‐deposited sputtered and PECVD Si films contain only an amorphous phase, whereas as‐deposited LPCVD films already has some crystalline phase. Third, the LPCVD phosphorus in‐diffusion into the substrate depends strongly on the initial film thickness, whereas for the other two methods, it is weakly dependent on thickness. Finally, the passivation quality of every poly‐Si film type has different responses to the film thickness and diffusion temperature, suggesting that the ex situ doping optimization should be performed independently.
Genetic Diversity of Wild Grapevine [Vitis vinifera L. subsp. sylvestris (Gmel.) Hegi] in the Eastern Adriatic Region

The genetic diversity of wild grapevine [Vitis vinifera L. subsp. sylvestris (Gmel.) Hegi] in the eastern Adriatic region, which includes Croatia and Bosnia and Herzegovina, has previously not been documented. Natural populations of wild grapevine were identified in their natural habitats, and their genetic diversity was studied and compared with both local and widespread European cultivars. Ninety-two grapevine genotypes were determined at 21 nuclear microsatellite loci, including 53 wild grapevine individuals, 32 diverse local Croatian and west European cultivars, and seven commonly used rootstocks. Two hundred thirty-nine alleles were detected, with a mean of 11.4 alleles per locus and high heterozygosity, ranging from 0.461 to 0.897 for observed heterozygosity and from 0.391 to 0.837 for expected heterozygosity. The genetic diversity of the wild grapevines was slightly lower than that observed in cultivars. Distance- and model-based cluster analysis differentiated three main groups, indicating clear separation between wild, cultivated, and rootstock accessions. This study greatly contributes to knowledge of genetic diversity in local wild grapevine populations in Croatia and Bosnia and Herzegovina, and provides necessary information for their conservation and further characterization.
A search for appropriate anchor tenants in shopping malls in Lagos metropolis

Anchor tenant which have been regarded as tenants in shopping mall that propel visitation and activities in the mall has been studied majorly in line with its impact on customers, other shopping outlets and generally on the mall. There appears to be no work on a search for the constituents of anchor tenant in the mall. This happens to be the crux of the present study with emphasis on three notable malls in Lagos Metropolis, The Palms Mall, Ikeja City Mall and Adeniran Ogunsanyan Shopping Mall. A total of 207 questionnaires were distributed to customers of the mall using the mall intercept approach of which a cumulative response rate of 81% was achieved. Data collated which was geared towards ascertaining the stores/products offered that attract the customers to the malls was rated on a likert scale of 5 and analysed using the Relative Importance Index and result substantiated with the chi-square test of significance both at the 0.05% and 0.01% level of significance. The study advocated that mix of the plethoric of Departmental Stores (4.7917); Entertainment centres (4.6250); clothing foot wares and accessories (4.5833); Electronics and electrical appliances (4.4881); food and beverage (4.4583); food stuff (4.2381); Watches, jewellery and ornament (4.1904); and Financial Services (4.0000) will be best suited as anchor tenants in the study area.

Detection of Image Forgery Using Information Standard Method With SVM

Depending on various features, image forgery is now used to enhance and restore images to make them more significant, whereas image forgery is performed by vulnerable people to generate fake truths by tampering images. From large (image) databases, a specified number of images forgery, new mechanism will have implemented to detect systems which is mainly based on two procedures. The first procedure relies on extract features of image through filters (LBP, Gabor, PCA and DCT) to find out its efficiency evaluated using some Statistics Measurements(Mean, Variance) and the second procedure relies on several quality metrics in optimization processes which (PSNR, MSE, AIC) have been calculated to which results in better quality compared to other image by combining selected filters with SVM, and, through experimental test, it was found that this proposed method of detect forgery technique is powerful than the classical detect system. The proposed methodology gives the better accuracy up to 98.5%, to detect and extract all type of forgery, with image enhancement capabilities.
Properties of (001) 
NaNbO3
 films under epitaxial strain: A first-principles study

First-principles calculations are performed to investigate and analyze properties of (001) thin films made of the most complex perovskite system, namely, $\mathrm{Na}\mathrm{Nb}{\mathrm{O}}_{3}$ (NNO), and are subject to epitaxial strain. In particular, an energy-versus-misfit strain phase diagram is constructed and reveals the existence of three different ground states for different strain regimes. For large compressive strain and up to moderate tensile strain, a monoclinic $Cc$ phase occurred, with its polarization and axis of antiphase tilting both rotating within a ($\overline{1}10$) plane with the magnitude of the strain. For large tensile strain, a ferroelectric orthorhombic state of $Pmc{2}_{1}$ symmetry emerges with polarization lying along the [110] in-plane direction together with an octahedral tilting adopting the ${a}^{\ensuremath{-}}{a}^{\ensuremath{-}}{c}^{+}$ pattern and an antiferroelectric vector associated with the reciprocal zone-border $X$ point. Finally, in between and for a narrow region of strain, a complex ground state is found. It has orthorhombic $Pca{2}_{1}$ symmetry, for which a complex tilting pattern coexists with polarization pointing along the [001] out-of-plane direction and antiferroelectric displacement associated with the $\mathrm{\ensuremath{\Delta}} k$ point located halfway between the zone-center $\mathrm{\ensuremath{\Gamma}}$ and zone-border $X$ point. Ferroelectric, antiferroelectric, and antiferrodistortive properties are also reported and discussed as a function of misfit strain.
Monitoring System of Heart Rate, Temperature and Infusion in Patients Based on Microcontroller (Arduino Uno)

A patient who is hospitalized generally gets health monitoring including 3 parameters including heart rate, body temperature and level of intravenous fluid usage. These three parameters are used as an indication of the patient’s significant health development. Body temperature is needed because in addition to being an indicator of a person’s health, it also has little to do with heart performance, namely the more the body temperature moves away from normal body conditions, then it affects how fast or slow the heart pumps blood. throughout the body. To solve this problem, the researchers intend to create a three-parameter monitoring system, namely heart rate, body temperature and intravenous drips for patients. This monitoring system is also designed to provide a sound warning indicator in case of abnormal conditions in the monitored parameters. From the test results, it can be concluded that the device can display indicators of patient health development with 3 parameters, namely heart rate, body temperature and the level of infusion usage.
Prevalence, Awareness, Treatment and Control of Hypertension Among Adults Living in the Port City of Boma, Democratic Republic of the Congo

Background and Aim: In limited resource settings, reliable epidemiological data generated from hypertension high risk geographical areas or people is a prerequisite for the planning of proven and effective interventions. The aim of the present survey was to assess the prevalence, awareness, control and factors associated with hypertension in adults living in the port City of Boma, located in the southwestern part of DRC. Methods: a cross-sectional survey using a modified WHO STEP wise questionnaire for data collection during face-to face interviews was conducted from March, 1 to April 15, 2018. We did multi-stage cluster sampling. Was an all-inclusive adult over the age of≥18 years having given informed consent. Information on demographic parameters, lifestyles, anthropometric measurements and blood pressure (BP) were obtained. Hypertension was defined as a mean of two BP≥140/90 mmHg or a self-reported history of antihypertensive drug use. Independent factors associated with hypertension were identified using logistic pressure analysis. P<0.05 defined level of statistical significance. Results: The prevalence of hypertension was 35% (Women 63, 5%) with 56,1% of hypertensive participants being unaware of their hypertension status. Of those who were aware and on treatment, only 47, 9% had a controlled BP. Older age (p<0.001), FH-HT (p=0.021), smoking (p<0.001), overweight (p<0.001), and obesity (p=0.030) emerged as main cardiovascular risk factors associated with hypertension. Conclusion: Hypertension was characterized by a high prevalence, low rate of awareness and suboptimal BP control, high cardiovascular risk and associated with smoking and obesity as modifiable risk factors. Therapeutic lifestyle changes and pharmacological treatment are needed for those hypertensive participants with increased global cardiovascular risk.
Populations of high‐value predators reflect the traits of their prey

The extent to which prey traits combine to influence the abundance of predators is still poorly understood, particularly for mixed predators in sympatry and in aquatic ecosystems. In this study, we characterise prey use and distribution in iconic bird (grey wagtails and Eurasian dippers) and fish species (brown trout and Atlantic salmon) to assess whether prey traits could predict populations of these four riverine predators. Specifically, we hypothesised that: 1) prey key traits would predict predator populations more effectively than 2) diversity of prey traits, 3) the taxonomic abundance or richness of prey (known as traditional or mass‐effect types of biodiversity) or 4) the prevailing environmental conditions. Combined predator population sizes were predicted better by a few key traits – specifically those revealing prey habitat use, size and drifting behaviour – than by prey diversity or prey trait diversity or environmental conditions. Our findings demonstrate that the complex relationships between prey assemblages and multiple predator species can be represented mechanistically when the key prey traits that govern encounter and consumption rates are identified. Given their apparent potential to reveal trophic relationships, and to complement more traditional measures of prey abundance, we advocate further development of trait‐based approaches in predator–prey research.
The Overlap Between Teen Dating Violent Offending and Violent Victimization

Teen dating violence (TDV) affects both males and females, and the negative consequences associated with such violence last into adulthood. This study had three objectives: (a) determine the extent of overlap in TDV offending and TDV victimization, (b) test whether social ties explain the TDV overlap, and (c) assess whether the effects of social ties on teen dating violence are invariant between sexes. This study used data from the 2018 Arizona Youth Study (N = 5,189). The findings confirmed that TDV overlap exists. In addition, social ties appeared to partially explain this overlap. Finally, some social ties appeared more general, predicting TDV for both sexes, whereas others were not. For instance, Paternal Attachment was found to reduce the probability of dating violence among female participants only. The findings lend support to prevention programs that aim to strengthen ties between parents and teens.
Examining the Predictors of Resilience and Work Engagement during the COVID-19 Pandemic

Previous studies have acknowledged the importance of resilience in enabling individuals to cope and bounce back from crises and unexpected situations like the COVID-19 pandemic. Thus, this study advances conservation of resources theory by investigating the job, social, and personal resources underlying employees’ resilience, and the impact of resilience in stimulating job engagement amid the COVID-19 pandemic. The model was tested using data collected from 259 employees in Malaysia. Results of path modeling analysis revealed significant impacts of self-efficacy, facilitating conditions, and family and friends’ support on employees’ resilience. Besides, resilience was significantly associated with job engagement. Our findings suggest that management concerns for employees may not enhance employees’ resilience amid the COVID-19 pandemic. Nevertheless, management could stimulate their employees’ resilience by providing them with the flexibility to spend quality time with their loved ones and adequate support for enabling working conditions.
