Quality parameters of sunflower oil and palm olein during multiple frying

The refined sunflower and palm oils are used in the food industry for the production of fried potatoes. Literary data have shown that palm oil had less tendency to degradation than sunflower oil due to its fatty acid composition. However, palm olein is a palm oil fraction and therefore has a different composition of fatty acids. The aim of this study was to investigate the quality of the refined palm olein in relation to the refined linoleic type sunflower oil during the production of fried potatoes. The oil samples were used for multiple frying during the seven days (40 minutes per day at a temperature of 165oC). The peroxide value and free fatty acid content (acid value) were determined by standard analytical methods. The results showed that the peroxide value in sunflower oil and palm olein increased by 75.0% and 77.8%, while the acid value increased by 50.0% and 26.8%, respectively, in relation to their initial values in the fresh oil samples. Based on these results, it can be concluded that the palm olein was more suitable for frying. However, this finding cannot be reported with certainty because the quality of the oil depends on many more parameters, not only on those analysed in this paper.
Laser-Induced Flexible Electronics (LIFE) for Resistive, Capacitive and Electrochemical Sensing Applications

Engineering a cost-effective, flexible electronic device in a one-step fabrication process is quite challenging to perform. Herein, we have introduced a simple, low-cost, solid-state process for producing and printing of complex circuits using Laser-Induced Graphene (LIG). In the present work, LIG has been effectively and selectively formed from direct CO<sub>2</sub> laser ablation on a polyimide sheet. Varying CO<sub>2</sub> laser power and speed, the electrical conductivity of the LIG has shown a linear increment in the conductivity measurement. The laser-induced samples were structurally characterized using Scanning Electron Microscopy (SEM), EDX, X-ray Photoelectron Spectroscopy (XPS), Raman spectroscopy. The results show a one-step method to create Graphene-derived structures on the polyimide sheet surface. This method of generating LIG on a flexible substrate (polyimide sheet) offers an easy way to fabricate Laser-Induced Flexible electronics (LIFE) circuits. Using this, the feasibility and the realization of a capacitive touch sensor and liquid level sensor has been successfully demonstrated. Further, as a prototype system, the LIG was examined for the H<sub>2</sub>O<sub>2</sub> electrochemical sensing application. It gives an appreciable response for the detection of H<sub>2</sub>O<sub>2</sub> in comparison to other carbon-based electrodes with limit-of-detection (LOD) as <inline-formula> <tex-math notation="LaTeX">$0.3~\mu \text{M}$ </tex-math></inline-formula> in a linear range from <inline-formula> <tex-math notation="LaTeX">$1~\mu \text{M}$ </tex-math></inline-formula> to 10 <inline-formula> <tex-math notation="LaTeX">$\mu \text{M}$ </tex-math></inline-formula>.
THE ABILITY OF Lactobacillus plantarum BSL IN REDUCING THE TISSUE DAMAGE OF LIVER AND SPLEEN IN RATS INFECTED BY Listeria monocytogenes ATCC 7644

Lactobacillus plantarum BSL, previously isolated from Indonesian sauerkraut. In this study, we investigated the ability of L. plantarum BSL in reducing the tissue damage of liver and spleen in rats infected by Listeria monocytogenes ATCC 7644. Treatment group of rats received 0.5 mL culture suspension (10 9 CFU/mL) of L. plantarum BSL and control group received 0.5 mL of 0.85% w/v NaCl daily for nine days of experiment. Both groups were infected at 3rd day with 0.5 mL of suspension of L. monocytogenes (10 9 CFU/mL). At the 2 nd (before infection), 5 th , 7 th , and 9 th day (after infection), the rats were sacrificed and then, liver and spleen were assessed for histopathological. Our study revealed that the administration of L. plantarum BSL could be able to reduce the liver and spleen damage of the experimental rats .
Crecimiento y perfil bioquímico de Chaetoceros muelleri cultivada en sistemas discontinuos y semicontinuos Growth and biochemical profile of Chaetoceros muelleri cultured in batch and semicontinuous systems

We characterized the growth and biochemical composition of a Chaetoceros muelleri strain from the Araya Peninsula, Sucre, Venezuela. The microalga was cultured under laboratory conditions (25 ± 1oC, 156 µE m –2 s –1 and 12:12 photoperiod) during 13 days, using two culture methods: batch and semicontinuous culture with a daily renewal rate of 30%. Cell density was determined and cells from each treatment were measured. The protein, lipid, carbohydrate and fatty acid contents were quantified to compare the quality of the Araya strain in both culture systems. Cell density showed little variability in the semicontinuous system during the steady-state phase (1.3 × 10 6 cells mL –1 on average), but increased significantly in the batch system, reaching 3.5 × 10 6 cells mL –1 . Proteins, lipids and carbohydrates did not show significant variations in the semicontinuous system, with mean values of 21.4 ± 0.8, 18.4 ± 0.8 and 4.1 ± 0.1 pg cells –1 , respectively. In the batch system, however, these macromolecules showed greater variability: proteins 3.5–21.1 pg cells –1 , lipids 8.5–11.6 pg cells –1 and carbohydrates 4.2–18.1 pg cells –1 . Higher levels of saturated (47.5%) and monounsaturated (34.8%) fatty acids were found in the semicontinuous system, whereas the content of polyunsaturated fatty acids (31.4%) was higher in the batch system, in particular of eicosapentaenoic acid (EPA, 20:5 n-3) (16 ± 2% of total fatty acids). Cell size did not vary significantly in the two culture systems and the mean width and length were 5 and 7.5 µm, respectively. The Araya strain of C. muelleri can be used as a food source for cultured larvae, the semicontinuous system providing a more stable nutritional quality.
Local Vulnerabilities and Global Robustness of Coupled Dynamical Systems on Complex Networks

Coupled dynamical systems are omnipresent in everyday life. In general, interactions between individual elements composing the system are captured by complex networks. The latter greatly impact the way coupled systems are functioning and evolving in time. An important task in such a context, is to identify the most fragile components of a system in a fast and efficient manner. It is also highly desirable to have bounds on the amplitude and duration of perturbations that could potentially drive the system through a transition from one equilibrium to another. A paradigmatic model of coupled dynamical system is that of oscillatory networks. In these systems, a phenomenon known as synchronization where the individual elements start to behave coherently may occur if couplings are strong enough. We propose frameworks to assess vulnerabilities of such synchronous states to external perturbations. We consider transient excursions for both small-signal response and larger perturbations that can potentially drive the system out of its initial basin of attraction. In the first part of this thesis, we investigate the robustness of complex network-coupled oscillators. We consider transient excursions following external perturbations. For ensemble averaged perturbations, quite remarkably we find that robustness of a network is given by a family of network descriptors that we called generalized Kirchhoff indices and which are defined from extensions of the resistance distance to arbitrary powers of the Laplacian matrix of the system. These indices allow an efficient and accurate assessment of the overall vulnerability of an oscillatory network and can be used to compare robustness of different networks. Moreover, a network can be made more robust by minimizing its Kirchhoff indices. Then for specific local perturbations, we show that local vulnerabilities are captured by generalized resistance centralities also defined from extensions of the resistance distance. Most fragile nodes are therefore identified as the least central according to resistance centralities. Based on the latter, rankings of the nodes from most to least vulnerable can be established. In summary, we find that both local vulnerabilities and global robustness are accurately evaluated with resistance centralities and Kirchhoff indices. Moreover, the framework that we define is rather general and may be useful to analyze other coupled dynamical systems. In the second part, we focus on the effect of larger perturbations that eventually lead the system to an escape from its initial basin of attraction. We consider coupled oscillators subjected to noise with various amplitudes and correlation in time. To predict desynchronization and transitions between synchronous states, we propose a simple heuristic criterion based on the distance between the initial stable fixed point and the closest saddle point. Surprisingly, we find numerically that our criterion leads to rather accurate estimates for the survival proba-
Implementation and Evaluation of Management Guidelines for Atopic Eczema for Primary Health Care Nurses: A Pilot Study

The primary health care (PHC) management guidelines for nurses treating children with atopic eczema were developed in a baseline study. The purpose of this study was to implement and evaluate the guidelines through a pilot study in a district in Gauteng, South Africa, in order to identify challenges and to adopt or adjust the guidelines for use by primary health care nurses in South Africa. The ultimate aim is to improve the child’s eczema and quality of life. A process evaluation research design was followed. Data was collected through 1) in-depth interviews with PHC nurses and also with the parents of children treated by these PHC nurses, and 2) documentation using the patient files of these children. The results showed that some aspects of the guidelines were used and seen as helpful, especially the complete emollient therapy and the evidence based health education. A simplified version of the guideline will be promoted for use by PHC nurses. The more detailed guideline could possibly be used as a basis to develop a short course on atopic eczema for PHC nurses.
ACT for adolescents: Impact of a pilot group intervention on psychological wellbeing

Abstract Acceptance and commitment therapy (ACT) has substantial support in adult populations but less among adolescents. To date, very little research has evaluated whether it can be delivered in a highly accessible school context. This study examined a 6-hour, weekly ACT-informed school-based group intervention for adolescent girls, focusing on anxiety, depression and building psychological flexibility. Participants (N = 10) who completed the intervention experienced significantly lowered levels of anxiety and increased psychological flexibility, with postintervention scores for all variables trending in the expected directions. Findings provide preliminary support for the efficacy of the intervention and encourages further evaluation of ACT delivered in schools.
Cascade Deep Neural Networks Classifiers for Phonemes Recognition

: In the last few years, deep neural networks have taken the problem of automated voice recognition to a whole new level of accuracy. Where it provided the highest recognition rates whether on words or on phonemes. Voice recognition problem represents the first phase of automated speech recognition systems. In this research, we introduce the recognition of phonemes based on deep neural networks using the Convolutional Neural Network ‘CNN’. We will discuss two approaches of recognition, the direct approach by recognizing the phonemes using a single classification phase by obtaining the correct phonemes directly through the input. The second proposed approach uses several phases of classification by taking into account the types of phonemes and their classes (vowels, semi-vowels, explosive, etc.). In both approaches, we rely on the mel spectrogram transform where the acoustic signal is converted into a two-dimensional matrix within the frequency domain, this matrix is then inserted as the input of the deep neural network. We tested the proposed classifier on TIMIT database, obtained 57% accuracy in the direct approach and a higher accuracy of 61% using our proposed approach.
Microstructure, mechanical, ballistic property evaluation of RHA steel produced by continuous-casting route

This paper presents the commercial production of rolled homogeneous armour steel with 5 different thicknesses i.e. 20,30,40,50 and 80 mm through continuous casting route. All the plates display tempered martensitic structure. Tensile and charpy impact properties are obtained for all the different thickness plates. It is observed that the produced steel shows a good combination of strength and impact toughness. For ballistic evaluation 30 mm thick plates are impacted with 30 mm medium caliber armour piercing steel projectiles at a velocity of 460±20 m/s at zero degree angle of impact. Depth of penetration method is used to measure the ballistic performance of the plates. From the post ballistic microstructural observations, an adiabatic shear band induced material removal is detected in the front face of the impacted rolled homogeneous armour steel plates. The microstructure, mechanical and ballistic properties of the continuous cast steel is compared with the steel produced by conventional ingot cast route.
Association of human papillomavirus type 16 E2 with ChlR1 : implications for E2 function and the HPV life cycle

Human papillomavirus (HPV) E2 is essential for transcriptional regulation of viral oncoprotein expression and the replication and persistence of episomal HPV genomes. Episomal persistence is mediated by tethering of viral genomes to host cell chromosomes during mitosis. Previous work demonstrated that interaction of E2 with the cellular DNA helicase ChlR1 is necessary for viral genome tethering. Therefore, disruption of this interaction is a potential therapeutic target for persistent HPV infections. To investigate the use of fragment-based drug discovery in the development of novel inhibitors of the E2-ChlR1 interaction, a fragment library was screened to identify those that bind E2 and several hits were identified. Concurrently, the interaction between HPV16 E2 and ChlR1 was characterised and shown to be a direct protein-protein interaction. The binding sites within E2 and ChlR1 were mapped and this information was used to identify a mutant E2 protein unable to bind ChlR1 (E2-Y131A). E2-Y131A was functionally characterised. HPV16 genomes encoding E2 wild type and Y131A were transfected into primary human keratinocytes to study the differentiation-dependent virus life cycle. Mutant genomes failed to establish genome maintenance, providing strong evidence that the interaction between HPV16 E2 and ChlR1 is necessary for the persistence of HPV infection.
Sustaining dancer wellbeing through independent professional dance careers

Dancers dedicate their lives to their art. The lucky few dancers who reach professional careers, must navigate a casualised industry, balance financial pressures and maintain performance fitness. This research aimed to provide practical considerations for dancers to support their health and wellbeing through independent, professional dance careers. Dancers from Australian contemporary dance company Co3 participated in a training program involving psychological and physiotherapy assessments and fitness training in conjunction with a major performance season. Focus groups with company dancers and staff investigated the perceived efficacy of the training program within the company schedule and in supporting dancer wellbeing. Dancers were highly engaged with the training program. Dancers expressed various benefits and challenges in incorporating the training within the demands of their careers. Themes identified from the dancer responses included making time, program specificity, dance fitness, connecting as a company, dancer monitoring and scheduling. A need to maintain collegiality outside of contracted times through communities of practice was identified across many of the themes. It is posited that the human capital of dance is challenged through the casualisation of the dance sector and requires careful attention from aspiring dancers.
Metasurface inverse design using machine learning approaches

Conventional metasurface design methods usually require a lot of computational resources and time, meaning they fail to satisfy the efficient, rapid design on demand. On account of this, we branch out of the conventional metasurface design methods by attempting to relate the emerging discipline of artificial intelligence to a traditional physical area. With our method, named AMID, metasurface structures are designed inversely where they can be computed directly by simply proposing and inputting the desired design targets into AMID. AMID greatly simplifies conventional methods that call for not only sufficient professional knowledge but also trial and error through simulation softwares. According to the design results, unit cells of metasurfaces are successfully computed, which verifies the availability of AMID and improves the design efficiency in the meanwhile.
A systematic review into the effectiveness of Integrated Offender Management

Integrated Offender Management was introduced by the Home Office and Ministry of Justice in 2009. Since its introduction, it has been piloted, developed and implemented across probation and policing areas within England and Wales. The scheme aims to reduce reoffending through the targeting of specific cohorts of offenders within local areas. Understanding its overall effectiveness would therefore be paramount in supporting its ongoing development. This article presents a systematic review of the research regarding the effectiveness of Integrated Offender Management. There were 15 articles reviewed in this regard, using a search criterion and assessment of the research aims. The findings revealed key areas which impact upon effectiveness: partnerships; locality and offender cohorts; finance; and workforce.

Induced ovulation and larval rearing of four species of Australian marine fish

This thesis developed techniques for the large-scale breeding of marine fish in New South Wales. It provides the first published account of the hormone induction and larval rearing to metamorphosis of Australian bass Macquarie novemaculeata (Percichthyidae), snapper Pagrus auratus (Sparidae), mulloway Argyrosomus hololepidotus (Sciaenidae) and sand whiting Sillago ciliate (Silliganidae) in Australia. Wild-caught broodstock were induced to spawn using hormones (hCG, LHRHa, Ovaprim) and either spawned naturally or were stripped. Pagrus auratus and S. ciliate were found to be multiple spawners with asynchronous ovaries. Conversely, M. novemaculeata and A. hololepidotus were found to be highly fecund single spawners having group synchronous ovaries. All four species were successfully induced to ovulate after periods in captivity ranging from one to five years. Species specific differences in hormone induction were determined, particularly in relation to the overripening of eggs and the optimum time between treatment and stripping. Commercial scale batches of larvae were reared in 2000 L conical tanks and replicated experiments were conducted in aquaria ranging in size from 2 to 70 L. Larval development for all four species was described and egg size, time to hatch, size at hatch, yolk size, oil globule size, and beginning of exogenous feeding were compared among species. First feeding larvae were reared on rotifers Brachionus plicatilis and then brine shrimp Artemia sp. Survival, growth and weaning of larvae at metamorphosis were compared. Factors affecting larval survival, particularly those influencing initial swim bladder development were tested in replicated laboratory experiments. The timing of swim bladder inflation was found to coincide with the start of exogenous feeding but feeding was not required for initial swim bladder inflation. Larvae that failed to inflate their swim bladder grew poorly and were susceptible to stress induced mortality. Light intensity, was shown to be an important factor influencing swim bladder inflation in cultured larvae. The effect of light intensity on inflation in M. novemaculeata and S. ciliate was quantified. Exposure to continuous light (100-200 Lux) inhibited inflation in M. novemaculeata. In contrast, S. ciliate were shown to have a diel pattern of nocturnal inflation and required higher light intensities to feed (1000 Lux). Manipulative experiments with S. ciliate larvae showed that they responded to darkness by inflating their swim bladders. Other abiotic factors such as surface access, low salinity and high aeration were shown to reduce inflation in larvae. Initial swim bladder inflation strategies are discussed and recommendations made regarding the importance of maximising inflation. The results of the study were used to assess the relative difficulty of intensive commercial production of each species for aquaculture.
Energy R&D Investments and Emissions Abatement Policy

The study examines the interactions of the energy R&D investments and the CO2 abatement policy using an endogenous energy R&D climate-economy model. Energy R&D investments affect the carbon emissions directly through efficiency improvements and indirectly by changing the comparative advantages of resources. This study considers the R&D investments in energy efficiency and low-carbon technology and explores how energy R&D investments accelerate the energy transition from fossil fuels to low-carbon technology. Three policies of carbon abatements are considered, namely, the optimal policy, the 2 ଌ policy, and the 1.5 ଌ policy. From the perspectives of benefits and costs, the optimal policy leads to the least abatement costs compared to the other two abatement policies. This study indicates that the more restrictive the abatement policy is, the more severe economic damage is caused in the short run, but more economic welfare is gained in the long run.
