Abstract

Cake is a popular bakery product consumed by almost everyone due to its low economic cost and shelflife, however, it is recognised unhealthy because of high fat and sugar contents. The aim of this study was to evaluate physicochemical and sensory properties of muffins baked using 100% of sugar and fat replacement as stevia sweetener (rebaudioside A and erythritol) and chia seed mucilage, respectively. The combination of sweetener with chia gel (SCC) had the highest moisture content, while the replacement of fat in muffin (CC) revealed similarity to the control in lightness and redness values. There was also no significant difference in terms of firmness when only the sweetener was replaced (SC). While the control muffin obtained the highest overall acceptability score, the lowest score was observed in CC. Thus, muffins with reduced fat and sugar contents can benefit the consumer in terms of health, but further optimisation of formulations for both replacers is needed for better sensory acceptance.

Abstract

Seventeen samples of Calabrian ewe’s milk, ewe’s cheese (Pecorino del Poro) made with raw milk, goat’s milk, and goat’s cheese (Caprino d’Aspromonte) made with raw milk were used to obtain 124 yeast isolates. The most abundant species was Debaryomyces hansenii (61.3%), followed by Candida zeylanoides (32.3%) and Kluyveromyces marxianus (3.2%). The enzymatic profile of 25 selected yeast strains was determined. Lastly, they were studied for their interaction with eight dairy lactic acid bacteria – four coccal-shaped and four rod-shaped. The best strains may be used as adjunct cultures for cheese making.

Abstract

Ball and Beam system is one of the most popular and important laboratory models for teaching control systems. This paper proposes a new control strategy to the position control for the ball and beam system. Firstly, a nonlinear controller is proposed based on the backstepping approach. Secondly, in order to adapt online the dynamic control law, adaptive laws are developed to estimate the uncertain parameters. The stability of the proposed adaptive backstepping controller is proved based on the Lyapunov theorem. Simulated results are presented to illustrate the performance of the proposed approach.

Abstract

Depression is a common psychiatric disorder that can be continuous or recurrent. It has been previously reported that intestine probiotics play an essential role in the bidirectional communication of the intestine and brain. This study aims to investigate the antidepressant effects of kefir, a probiotic supplement, and Lactobacillus rhamnosus GG and their potentials in depression-like behaviour treatment in two-week and four-week treatments. In the present study, BALB/c mice were used for this purpose. The saline- and fluoxetine-treated groups were designed as negative and positive control groups, respectively. The forced swimming and tail suspension tests have been performed to assess the level of depression-like activity. We have observed that two-week treatment reduces the duration of depression-like activities, and four-week treatment enhances the antidepressant properties. Overall, our results suggest that kefir, L. rhamnosus GG, and the investigated probiotic supplement have antidepressant-like properties.

Abstract

Cyclodextrins are widely used in various fields including food industry. In this review, their role in high carbohydrate-containing, starchy foods are reviewed and discussed. Both the effects as functional ingredients affecting the structural properties of starch and as active ingredients slowing down starch digestion and, as a consequence, decreasing the glycaemic index of starchy foods are overviewed without considering the traditional applications as carriers and stabilisers of aroma and flavour, essential oils, polyunsaturated fatty acids, and other bioactive components to enrich foods, even if they are carbohydrate foods. The effect on starch metabolism is explained by the structural transformations caused by cyclodextrins on starch amylose and amylopectin. Several examples are shown how the technological and sensorial properties of bread, rice products, pasta, and other starchy foods are modified by cyclodextrin supplementation, and how the digestibility is changed resulting in reduced glycaemic and insulinaemic effects.

Abstract

Tomato (Solanum lycopersicum L.) is one of the important vegetables in the world due to large production area and consumer interest. Biotic and abiotic stresses have negative effect on tomato production. Utilisation of rootstocks conferring resistance to biotic stresses can be considered as the most effective and environment friendly solution in tomato production to overcome this problem. Although wild tomato species is a good rootstock candidate due to its resistance to multiple plant diseases, effects of wild tomato species as rootstock on mineral nutrient composition and fruit quality are not clear. In the present study, effects of interspecific hybrids derived from two wild tomato species (Solanum habrochaites and Solanum penellii) as rootstock on tomato fruit mineral nutrient composition (phosphor (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu)) and fruit quality traits (soluble solids content (SSC), pH, percent titratable acidity (TA), and lycopene content) were evaluated. In the study, Amaron, Armstrong, and Arazi commercial rootstocks were used as control and AK0004 F1 (candidate tomato hybrid) was used as a source of scion. As result, only lycopene content was affected by different rootstocks. S. penellii was found to be with more potential for lycopene content. For mineral nutrient composition, all hybrids and controls had similar contents of potassium, phosphor, calcium, and magnesium. Manganese and copper contents decreased in all plants. S. habrochaites had more potential regarding nitrogen, iron, and zinc contens than S. penellii. This is the first study to evaluate two interspecific hybrids derived from S. habrochaites and S. penellii, and the results might be useful to understand effects of rootstocks derived from wild tomato species on mineral nutrient content and fruit quality.

Abstract

Location specific services are widely used in outdoor environment and their indoor counterpart is gaining more popularity as well. There is no standardized technology exists for indoor localization, usually smart phone is used as a localization platform and the field strength of an existing radio frequency infrastructure is used as the location specific information. Smart devices are also equipped with several sensors capable of capturing the motion data of the device. Detecting the walking step, turn, stairs motion type can refine the indoor position using digital indoor map as a reference. The real-time recognition of the motion type is possible with a precisely constructed and trained convolutional neural network and therefore it can improve the stability of the localization.

Abstract

Brigittaplatz located in the 20th district of Vienna, which is a mixed culture residential community with various issues. This paper attempts to uncover the existing problems, weaknesses, potential opportunities of the site and explore a set of local interventions to accomplish site regeneration through architectural and landscape measures. Study utilizes two axes to improve and reconnect the public service, green corridor as well as the interactive relationship. All the proposed interventions are not merely public facility renewal but a new functional and social design, which is trying to reactivate the various relationships in the site that can enhance the quality of life and carry over the impact to larger scales. Authors seek a holistic approach to regenerate Brigittaplatz.

Abstract

Multi-layer metamodeling is a metamodeling method that provides great flexibility for domain prototyping, while it also ensures rigid validation of domain rules. Visualization of multi-layer models would be essential in order to promote this new modeling technique in industrial setups; however, the traditional way of representing model entities is not sufficient here. Dynamic Multi-Layer Algebra is a multi-layer metamodeling approach that addressed the challenges of multi-layer modeling, but uses a text-based language to create models. This paper presents Dynamo, a visual notation for Dynamic Multi-Layer Algebra, which is also applicable to other multi-layer metamodeling approaches. The paper elaborates the graphical syntax and the design decisions.

Abstract

This paper studies the two widely used material models for predicting the dynamic behavior of soils, the Ramberg-Osgood and Hadrin-Drnevich models. Resonant column and torsional simple shear test results on dry sand were used to calibrate and evaluate the model built in the finite element software Midas GTS NX. Both material models are already implemented by the software. This study estimates the ability and efficiency of both soil models coupled with the Masing criteria to predict the behavior of soil when subjected to irregular loading patterns, (e.g., earthquakes), and measure the two most important dynamic properties, the dynamic shear modulus, and the damping ratio.
