Factors Determining Children and Young People’s Well-being at School
Authors: Stasulane Anita 
Published: January 2018

Abstract
The article addresses the issue of children and young people’s well-being at school. The issue has been known as topical for already some time. In recent decades, in order to be able to determine the true nature and essence of the phenomenon of well-being, the necessity to find the ways for identification of children and young people’s self-assessment of well-being at school has become very important. There are many challenges related to conducting new longitudinal studies on children and young people’s well-being. The phenomenon of well-being at school cannot be seen only in the context of local situation; it is deeply contextual. Its essence is also determined by the content and values that have emerged in the development of wider global or regional relations and attitudes. Therefore, for the formation of a broader perspective of the article, such phenomena as sustainability and unsustainability were used. This made it possible to refer to the trends of sustainability and unsustainability that had long been highlighted in the studies of global development and education. The analysis of the phenomenon of well-being at school is offered based on the research results within EU FP7 project “Measuring Youth Well Being” (MYWeB) that took a balanced approach to assessing the feasibility of a European Longitudinal Study for Children and Young People through prioritising both scientific and policy imperatives and was carried out in cooperation with eleven European countries. The aim of the article in accordance with one of the specific tasks of the project is to find out the meaning and significance that children and young people allocate to well-being. The article discusses one of the most relevant domains of wellbeing - school, and how it relates to happiness, life-satisfaction and psychological wellbeing of children and young people. The article outlines the results of fieldwork undertaken in project consortium countries (Croatia, Estonia, Georgia, Germany, Greece, Hungary, Latvia, Portugal, Slovakia, Spain, and the United Kingdom) with the goal to understand the subjective experiences of children and young people from different age groups, regions and socio-economic backgrounds. The results of the research confirmed that educational spaces could take a more significant role in promoting well-being of children and young people; in its turn, the education system must rebalance academic learning and emotional well-being.

Published: January 2018

AbstractThe geometry of weirs is a prime factor influencing hydraulic performance and accuracy. One of the geometric components of weirs, is the situation of its top corners, are they sharp or rounded, and what is the most suitable radius of such rounding curves? The present study was conducted to examine the effect of using five different radius of curvature for both the upstream and downstream top corners of a clear over-fall weir on its hydraulic performance and accuracy. Eleven models of wooden weirs were shaped and prepared with five different values of rounding curvature. The prepared weir models were located in a laboratory tilting flume of 13.50 m length, 0.30 m width, and 0.30 m depth. The study was carried out in the Irrigation and Hydraulic Laboratory of the Civil Department, Faculty of Engineering, Assiut University, Egypt. A discharge ranging from 2.0 to 22.0 dm3s−1was used, and through 66 experimental runs, all the necessary hydraulic parameters were measured, and recorded. The obtained data were tabulated, analyzed, plotted, and technically discussed. The main results and obtained conclusions proved that when the front weir top edge is curved the discharge coefficient increases up to 8%. Also, when both front, and behind weir top edges are curved the discharge coefficient increases up to 14%. At the same time the discharge coefficient has a maximum value when the radius of curvature in upstream and downstream top corners equals 20% of the height of the weir.
From carbonate platform to euxinic sea – the collapse of an Early/Middle Devonian reef, Cantabrian Mountains (Spain)
Authors: Loevezijn Gerard B.S. van , Raven J.G.M. 
Published: January 2018

Abstract
The Santa Lucía Formation represents the major phase in Devonian reef development of the Cantabrian Zone (Cantabrian Mountains, northwest Spain). In the present study the transition from the carbonate platform deposits of the Santa Lucía Formation to the overlying euxinic basinal deposits of the Huergas Formation is described. These transitional strata are connected to the Basal Choteč Event and represent a condensed sedimentation of micritic dark-grey and black limestones with an upward increase of dark shale intercalations with iron mineralisation surfaces and storm-induced brachiopod coquinas. The transitional beds are grouped into a new unit, the Cabornera Bed, which consists of limestone, limestone-shale and shale facies associations, representing a sediment-starved euxinic offshore area just below the storm wave base. Four stages in reef decline can be recognised: a reef stage, an oxygen-depleted, nutrient-rich stage, a siliciclastic-influx stage and a pelagic-siliciclastic stage. Additional geochemical and geophysical investigations are needed to verify the results presented herein.

Published: January 2018

AbstractIn this paper, we discuss the properties of simple modules over Auslander regular rings with global dimension at most 3. Using grade theory, we show the right projective dimension of$\begin{array}{} \text{Ext}_{{\it\Lambda}}^{1}(S,\ {\it\Lambda}) \end{array} $is equal to 1 for any simpleΛ-moduleSwith grS= 1. As a result, we give some equivalent characterization of diagonal Auslander regular rings.

Abstract
Procurement method over time has proven to have significant influence on the successful delivery of construction projects. Making the right decision in the selection of a procurement option to adopt is therefore crucial if a project is to succeed. This study therefore assessed the cost and time performance of selected public building projects procured using traditional, direct labour and management procurement options in Ondo State, Nigeria. A pro forma was used to gather cost and time data from government procuring entities in the state. In addition, a structured questionnaire was used to obtain information from construction professionals in these procuring entities, in order to ascertain the factors influencing the choice of procurement options adopted. The cost and time data gathered were analyzed using percentages and the paired-samples t-test, while those gathered on the factors influencing the choice of procurement options were analyzed using mean item scores and analysis of variance (ANOVA). The results revealed that although there is no significant difference between the initial and final costs of the assessed projects, some measure of cost overrun still exists. In addition, a considerable amount of time overrun was experienced on projects executed using the three different procurement options. The most significant factors influencing the choice of a procurement option are price competition, speed, time certainty and complexity of the project. It is believed that the findings of this study will provide public procuring entities with insight on the cost and time capability of these procurement methods and aid them in selecting the procurement option that will help in delivering public building projects within the budget and on schedule.

Abstract
This article presents strategies for teaching scheduling methods such as takt-time, flowlines, and point-to-point precedence relations (PTPPRs) using building information modeling (BIM) models in the Last Planner System. This article is the extended version of the article entitled “Teaching Takt-Time, Flowline and Point-to-point Precedence Relations: A Peruvian Case Study,” which has been published in Procedia Engineering (Vol. 196, 2017, pages 666–673). A case study is conducted in final year students of civil engineering at the Pontifical Catholic University of Peru. The mock-up project is an educational building that has high repetitive processes in the structural works phase. First, traditional tools such as Excel spreadsheets and 2D drawings were used to teach production system design with takt-time, flowlines, and PTPPR. Second, 3D and 4D models with Revit 2016 and Navisworks 2016 were used to integrate the previous schedules with a BIM model and to identify its strengths and weaknesses. Finally, Vico Office was used for the automation of schedules and comparison of the methods in 4D and 5D. This article describes the lectures, workshops, and simulations employed, as well as the feedback from students and researchers. The success of the teaching strategy is reflected in the survey responses from students and the final perceptions of the construction management tools presented.

Published: January 2018

Abstract

Introduction
. The aim of the study was to determine the changes in the peak torque of the knee extensors and flexors of the dominant lower limb, the shoulder internal and external rotators of the dominant upper limb, and the shoulder extensors and flexors of the dominant upper limb as well as the changes in jump height in volleyball players during the annual training macrocycle.

Material and methods
. The study involved 13 volleyball players from a Polish second-league team. The measurements were performed five times: before the preparation period (T1), at the beginning of the competitive season (T2), in the middle (T3) and at the end of the first competition period (T4), and after the competitive season (T5). The torque of the knee muscles and shoulder rotators was measured in isokinetic conditions, and the torque of the shoulder extensors and flexors was assessed in isometric conditions. Jumping ability was tested using a piezoelectric platform.

Results
. We observed statistically significant differences (p < 0.05) in jump height and relative peak torque between the measurements, except for the torque of the shoulder external rotators and flexors. The results of multiple factor analysis based on 5 sets composed of 5 strength variables revealed differences between subjects and measurement sessions.

Conclusions
. The results obtained indicate that strength and jumping ability should be assessed regularly during the competitive season. The findings of the study suggest that it is necessary to modify the training methods used during the preparation period and individualize the training in the final phase of the competition period.

Published: January 2018

Abstract

Introduction
. Breast cancer is the most commonly found type of cancer in women. One cancer risk factor related to lifestyle that seems to be particularly worth examining is physical activity. The aims of the study were to analyse the physical activity of women who had been diagnosed with breast cancer for the first time and had undergone surgical treatment as well as to determine how their physical activity patterns changed with respect to the patterns from before the diagnosis.

Material and methods
. The research was carried out by means of a diagnostic survey. The instrument used was an original questionnaire designed for the purposes of the study. A total of 200 female breast cancer patients were surveyed between September 2015 and April 2016. The data collected in the study were subjected to statistical analysis.

Results
. The study showed that after developing cancer, a considerable percentage of women who were not physically active earlier started to perform regular physical activity. Before being diagnosed with cancer, 58% of the respondents did not spend any time engaging in physical activity or only performed it up to 30 minutes per week, whereas after receiving the diagnosis, more than half of the respondents spent a few hours a week being physically active.

Conclusions
. After being diagnosed with breast cancer, the majority of patients led a healthy lifestyle; the women surveyed in the study were more active and spent more time engaging in sports and recreation.

Abstract
The study was carried out to investigate the influence of sous vide treatment (80 °C/15 min) and high pressure processing (700 MPa/10 min/20 °C) on nutritional characteristics of cowpea (Vigna unguiculata (L.) Walp. cv. Fradel) and maple pea (Pisum sativum var. arvense L. cv. Bruno) spreads after processing and 62-day storage at 5 ± 1 °C temperature, to evaluate overall acceptance of processed pulse spreads after 22-day storage and to analyse nutrient coverage of pulse spreads compared to reference intake for adolescents and adults. Pulse spreads were made of cooked pulse seeds to which salt, citric acid, oil, and seasoning was added. Pulse spreads were hermetically sealed under vacuum in PA/PE and PET/ALU/PA/PP pouches. Nutritional composition was determined according to standard methods; overall acceptance was determined using a 5-point hedonic scale. Nutrient coverage by one serving of pulse spreads for adolescents and adults was compared to nutrient recommendations given by the Ministry of Health of the Republic of Latvia. The results suggest that processing technologies and packaging materials did not influence nutritional value of pulse spreads (p > 0.1). Hedonic evaluation by consumers (n = 90) showed that processing technologies did not influence the overall acceptance of cowpea and maple pea spreads (p > 0.1).

Abstract
Meat consumption during the first year of life is especially important to provide necessary iron requirements. The aim of the study was to assess meat and meat product consumption of Latvian infants during their first year of life, in relation to different factors. Data were collected by interview method using two types of questionnaires: food frequency questionnaires and food diary. The study included a representative sample of infants and toddlers from all regions of Latvia with a target sample of 560 participants. The study included 266 infants: 127 girls, 139 boys, aged from 0 to 12 month. Data were summarised using the Excel software and analysed using the SPSS software. For data analysis two age groups were created: 0–5.9 months and 6–12 months. Consumption was analysed by two parameters: frequency and amount per feeding. Meat products were defined as offal products, sausages, and meat in baby food. Meat was mainly consumed after 6 months of age and by 73% of infants (n = 107). Meat from baby food was consumed only after 6 months and by 23% (n = 34). Sausages and offal products were consumed after 6 months of age. Sausages were consumed by 18% (n = 28) and offal products by 11% (n = 16) of infants. Meat consumption for the majority of infants was introduced after 6 months and was in accordance with recommendations.

Published: January 2018

Abstract
Differences in biochemical composition in dehulled and pearled grain samples affected by the various degrees of pearling were studied for spring barley (Hordeum vulgare L.). Twelve covered spring barley and two hulless genotypes were examined. Commercial samples of pearled barley were included for comparison. Covered barley grain samples were pearled using a small-scale barley pearler to obtain dehulled and pearled barley grain products with pearling percentage of 12% and 30%, respectively. Significant differences were observed in the chemical composition between dehulled grain and pearled grain. As the outer layers of the covered grain were removed to a greater degree by pearling, crude protein content, crude ash, total phenolic concentration and radical scavenging activity in the pearled grain significantly decreased (p < 0.001), while starch concentration increased, without changes in the β-glucans concentration. The concentration of phenolic compounds in the dehulled barley grain samples were 1.30 to 1.61 times higher than for pearled grains. There was a significant (p < 0.01) correlation determined among values of dehulled and pearled grain of different barley genotypes in crude protein, starch, and β-glucan content, but no relationship was found in total phenolic content and radical scavenging activity.

Abstract
Orange juices are an important source of bioactive compounds. Because of its unique combination of sensory attributes and nutritional value, orange juice is the world’s most popular fruit juice. Orange (Citrus sinensis) juice of Greek Navel variety was used in this study. The impact of Conventional Thermal Pasteurisation (94 °C/30') (CTP) and alternative Ultra-High Temperature (UHT) (130 °C/2') processing on bioactive compounds and antioxidant capacity changes of fresh Navel orange juice was investigated. Sensory attributes of processed juices were evaluated. Results showed that using technologies CTP and UHT orange juice Navel significantly changed vitamin C concentration in comparison with fresh orange juice. The highest concentration of antioxidants (vitamin C, total phenols, hesperidin and carotenoids) was observed in orange juice Navel produced by UHT technology. Sensory results indicated that characteristics of the orange juice obtained using UHT technology were more liked than the CTP heat treated juice. UHT technology emerges as an advantageous alternative process to preserve bioactive compounds in orange juice.

Published: January 2018

AbstractConcentration of trace and major elements is an important indicator of nutritional value of food, also regarding cultivated food crops like fruits, berries, and vegetables. Concentration of elements differs regionally and is influenced by various factors. Nevertheless, some chemical elements (As, Cd, Hg, Ni, Pb, Zn, etc.) are known as environmental pollutants and may affect the quality and safety of crops and food products. The aim of the study was to determine the concentration of potentially toxic elements like Cd, Cr, Cu, Fe, Ni, Pb, and Zn in samples of berries grown in allotment gardens of Rīga city. Dried and homogenised samples of raspberries, strawberries, red currants, black currants, gooseberries, and cherries were mineralised in a solution of concentrated HNO3/H2O2by heating on a thermoblock. Quantitative analysis of sample solutions was performed using atomic absorption spectroscopy. Potentially toxic elements were in concentrations as follows: Fe > Zn > Cu > Ni > Pb > Cr > Cd. Mean concentrations of the elements of the major concern were: Ni 0.54 mg/kg, Pb 0.20 mg/kg, Cr 0.10 mg/kg, and Cd 0.03 mg/kg. Results indicated significant variability of element concentration among the species.

Abstract
Fennel (Foeniculum vulgare L.) is an aromatic plant belonging to Apiaceae family widely cultivated elsewhere for its strongly flavoured leaves and seeds. Fennel seeds are of particular interest as a rich source of both vegetable and essential oils with high amounts of valuable components. However, residual cakes after oil extraction were typically considered as byproducts, in the present framework, the potential added value of these cakes was studied. The aim of this study was to investigate the effect of addition of fennel cake and seeds to protein bread quality. In the current research, a single-screw extruder, which is a solvent-free technique, was used for fennel seed oil extraction. For the protein bread making, fennel seed and cake flour in concentrations from 1 to 6% were used. Moisture, colour L*a*b*, hardness, total phenolic concentration, DPPH radical scavenging activity, and nutritional value of protein bread were determined. The addition of fennel cake and seeds had significant (p < 0.05) effect on bread crumb colour and hardness attribute, whereby the bread became darker and harder in texture than the control. Moreover, higher antioxidant activity and total phenolic concentration were observed for both protein breads enriched with fennel cake and seed flour. The overall results showed that addition of fennel cake and seed had beneficial effects on phenolic concentration, antioxidant activity and quality of protein bread. This result suggests also that added value of fennel seeds oil by-products could be increased by their utilisation in bread production.
