Variation in Diet Patterns of the Invasive Top Predator Sander lucioperca (Linnaeus, 1758) across Portuguese Basins

The introduction of non-native species is recognized as a major threat to biodiversity, particularly in freshwater ecosystems. Pikeperch Sander lucioperca, is a recent invader to Portugal, primarily providing commercial and angling interest. The aim of this work was to study the diet of this top predator across Portuguese basins and to evaluate its potential impact on recipient ecosystems. In total, 256 pikeperch stomachs from seven basins were examined, of which 88 (n = 34%) were empty. Pikeperch diet was dominated by R. rutilus, M. salmoides and Diptera in northern populations, while A. alburnus, P. clarkii and Atyidae were important prey in more humid highlands. Variation in diet was most strongly linked to latitude and ontogeny, with both size classes showing signs of cannibalism. The population niche breadth remained low and was accompanied by higher individual diet specialization, particularly in northern populations. Pikeperch dietary patterns denoted an opportunistic ability to use locally abundant prey in each ecosystem, and was size dependent, with larger individuals becoming more piscivores, causing a higher impact in the lotic systems. This first perspective about the pikeperch diet presents a very broad view of the feeding traits of this non-native predator across Portugal, being very important to deepen our knowledge about the impact of these introduced piscivores.

Biochemical characterization of juices from three wild fruit species consumed in Côte d’Ivoire "Adansonia digitata, Parkia biglobosa and Tamarindus indica"

In the context of the valorization and the development of local products in Côte d’Ivoire, this study is based on juices samples prepared from the pulp of wild fruits of Baobab (Adansonia digitata), Tomi (Tamarindus indica) and Néré (Parkia biglobosa). The physiochemical characteristics such as dry matter (desiccation, 105°C), mineral (spectrophotometer), ash, fat, fiber and protein (AOAC), Energy (coefficients), vitamins A & C (HPLC), organic acids & total polyphenols (HPLC), carbohydrate (by difference), pH and titratable acidity (titrimetry, NaOH) of pasteurized juices (75°C, 5 min) were investigated. Data showed that the juices have been characterized by low protein (0.21-0.28 %), fat (0.26-0.65 %) and ash (0.20-0.47 %) content and high level of total carbohydrates (21-30 %) and energy (85.83-124.43 Kcal/100mL). Baobab and Tomi juices were distinguished by their high acidity (103-159 meq.g / Kg) while Baobab and Néré juices were characterized by their average fiber content (4-5.30 %). The juices of Baobab, Tomi and Néré are very rich in some minerals (K and Mg) but calcium (Ca) and iron(Fe) are not bioavailable (Oxales/Ca and Oxalates/Fe ˃ 2). The juice of baobab is rich in vit A (80 mg/100mL) and vit C (189 mg/100mL) than the others juices. Catechin was the most phenolic content (52.29-110.32 mg/100mL) where tartric acid was the most organic acid (4.02-6.82 mg/100mL) in the juices. The knowledge of the nutritional value of these juices could contribute to a better understanding of the essential role of these three wild fruits in terms of food and trade.

Effect of Magnetic Treatment of Water or Seeds on Germination and Productivity of Tomato Plants under Salinity Stress

Salinity is an abiotic stress that reduces the seed germination and productivity of tomatoes. Magnetic treatment has been shown to have a positive effect on the seed germination, seedling growth, and productivity of various crop species. Therefore, three experiments were conducted to evaluate whether treating saline water or seeds with a magnetic field can improve the seed germination and productivity of tomatoes (Solanum lycopersicum) under salinity stress. To evaluate seed germination and seedling growth in response to a magnetic field, two laboratory experiments were carried out by passing four saline water solutions of NaCl (0, 5, 10, and 15 dS/m) through a magnetic field (3.5–136 mT) or exposing tomato seeds to the same magnetic field for 20 min before sowing. In a greenhouse experiment, plants were irrigated with different magnetically-treated and untreated saline water solutions to evaluate plant growth. Magnetic treatment of water or seeds improved seed germination percentage, speed of germination (lower mean time to germination), and seedling length and dry weight in the two laboratory experiments, especially under salinity stress of 5 and 10 dS/m. As the salinity level increased, germination performance and plant growth were significantly decreased. Irrigating tomato plants with magnetically-treated water improved plant height, stem diameter, and fruit yield per plant compared to untreated water, especially under salinity of 0 and 5 dS/m. In conclusion, magnetic treatment of saline water or seeds improved germination performance, plant growth, and fruit yield of tomatoes under saline conditions.
Content of selected essential metals in the meat of perch (Perca fluviatilis) from north-central Poland

The aim of the present study was to analyze the impact of sex and localization on the levels of microelements (Cu, Zn and Fe) in the meat of perch (Perca fluviatilis L.) collected from the Bay of Puck (S1), the Vistula Lagoon (S2), the Vistula River (S3), the Drwęca River (S4) and the Włocławek Dam Reservior (S5). The study involved 83 sexually mature individuals of fish caught in autumn, divided into females and males, and having the body length in the range from 15.5 to 18 cm. The muscles samples were taken from the large side muscle of the fish body above the lateral line. Metal concentrations were determined by atomic absorption (AAS). The concentration of metals decreased in the following order: Zn > Fe > Cu and statistically significant differences were observed in the Zn, Fe and Cu content in the meat of fish collected from different water bodies. The mean content of Cu ranged from 2.97 mg kg-1 (S5) to 28.75 mg kg-1 (S2), Zn from 23.43 mg kg-1 (S3) to 53.09 mg kg-1 (S5) and Fe from 19.18 mg kg-1 (S3) to 38.38 mg kg-1 (S5). Sex was a factor differentiating the content of Cu in each sampling location. Correlation analyses confirmed statistically significant and negative correlations between Cu-Zn (r = -0.48) and between Cu-Fe (r = -0.51). The relationship between Zn and Fe was positive and statistically significant (r = 0.64). The sampling sites significantly affected metal-metal interactions. The research indicated that consumption of 100 g of perch meat could cover over 60% of daily requirement for Cu, and 13 and 7%, respectively, for Zn and Fe.

Family capital and parental involvement among parents in public elementary and secondary schools in the Philippines: perspectives of parents and children

ABSTRACT This paper examines the different forms of family capital in the context of parental involvement in children’s schooling. This paper has three-fold goals. First, it ascertains the level of parental involvement of Filipino parents as perceived by the parents themselves and their children. Second, it investigates the impacts of various forms of capital on parental involvement. Third, it determines which type of capital will have a significant impact on parental involvement. This paper is based on a survey among elementary and secondary students and their parents of purposively selected 29 elementary and secondary schools in the Philippines. These schools were selected as they were part of a corporate social responsibility project. This paper concludes that parental involvement among parents from low-income households is generally low. Parents are relatively more involved in parenting for education. Results of the multiple regression analysis reveal that membership in CCT (Conditional Cash Transfer), participation in community activities, parent’s level of education, and family size predicted parental involvement. The results point to the idea that parents with better social and human capital are likely the ones who will be more involved in their children’s education.
Development of Student Islamic Behavior Through Worship Practice Activities at SMAN City of Bandung

This study aims to describe the development of Islamic behavior of students through the practice of worship at SMAN Bandung. Based on observations and interviews of researchers to several principals of SMAN schools in Bandung who have athlete students, found that not all students who profess to be Muslim to perform worship well during sports practice while in school, only some students who want to perform worship in school, such as performing sunnah prayers or obligatory prayers in school mosques , on the grounds that his clothes are dirty because of sweat, responsibility is training and clashing with training time. Whereas if praying his clothes must be clean and holy. Sometimes, even many students have not prayed if they are not ordered and many others lack. Not infrequently students who when at home and at school show good Islamic behavior, but when outside the house and outside the school shows bad behavior seen in terms of Islam, such as smoking, hanging out on the side of the road, and excessive dating. This study uses qualitative approach with descriptive method. Data collection techniques through interviews, observations, and documentation. Data analysis techniques use data analysis techniques consisting of data reduction, data presentation, and drawing conclusions. The results of this study are: 1) Islamic behavior development program in high school in Bandung, namely congregational prayers before the start and at the end of teaching and learning activities, memorizing Asmaul Husna, reading the Quran 15 minutes before the first hour. 1) learning begins, praying dhuha congregation, praying midday congregation, infaq or setting aside some pocket money for alms. 2) The process of fostering islamic keisk behavior of students through religious practice activities in SMAN throughout Bandung needs to be held, religious lectures, guidance and supervision. 3) The behavior of students after receiving guidance through the practice of worship in SMAN throughout The City of Bandung is quite good. Students can be responsible and disciplined in performing worship. Students can also work together and socialize well.
Influence of Energy Drinks on Pharmacokinetic Parameters of Sildenafil in Rats

Both sildenafil and RED BULL®(energy drink) are claimed to boost up energy.RED BULL®, one of the most commonly used energy drinks and its easily and widely available for daily use, the idea of this research work had arisen from observations about the concomitant use of sildenafil with RED BULL® by men seeking for better sexual performance. To study the effect of RED BULL® on the pharmacokinetic profile of sildenafil by using HPLC.The pharmacokinetic parameters (Cmax, Tmax and AUC) were determined in 10 rats following oral administration of 0.57 mg/ml sildenafil with and without RED BULL® in crossover design, to achieve this purpose,simple, rapid and accurate method for validation and determination of sildenafil in rat plasma in the presence of RED BULL® has been developed. This was performed using High-Performance Liquid Chromatography- Ultra Violet (HPLC-UV). The pharmacokinetic data showed that sildenafil plasma level was lower when combined with RED BULL® According to the results obtained, maximum concentration (Cmax) for sildenafil alone was (162.05 ng/ml) after 0.5 hours of administration. The Cmax decreased to (44.68 ng/ml) after 0.5 hoursof administration RED BULL® concomitantly with sildenafil which showed a significant effect on sildenafil plasma level (P<0.001). The area under the curve (AUC) decreased significantly from (370.53 ng/ml*hr) for sildenafil alone to (87.74 ng/ml*hr) when combined with RED BULL®. RED BULL® can alter sildenafil pharmacokinetic if they were taken together.
STEM Education Implementation in Indonesia: A Scoping Review

In Indonesia, STEM education has been implemented in the learning process since 2014. The number of researches on the implementation of STEM education are increasing from year to year. Therefore, this research was conducted to map the all articles published online with the theme of STEM education implementation in Indonesia. The scoping review was carried out following the framework from Arksey & O'Malley (2005), with the following steps: (1) formulating research questions, (2) exploring research results on Google Scholar database from 2015-2020 with the keyword “implementation” + "STEM education" + “Indonesia”, (3) sorting the collected articles with predetermined criteria and selecting them according to the PRISMA model, (4) discussion, and (5) conclusion. Found 597 articles that match to these keywords and 154 articles that meet the criteria as research data. The results showed that the STEM education is implemented as a learning strategy and approach, integrated with other learning models, used as a learning assessment, and developed into teaching materials, modules, and learning media. Additionally, teachers implement STEM to improve entrepreneurship skills, learning motivation, and various 21st-century skills in their students. Furthermore, research on STEM has been conducted in 19 provinces in Indonesia, which are dominated by West Java and East Java provinces. Beside that, the STEM education has been studied at all levels of education and high school is the most widely used research subject and STEM education has grown in small units and has proven to be capable of developing many student skills. The implementation of STEM education can be a trigger for renewal in the world of education.
Vortex breakdown mechanics of a laminar confined swirling flow with large expansion ratio using a non-uniform finite difference approximation

Abrupt expansions are a very frequent geometry in mechanical engineering systems, i.e. in combustion chambers, valves, heat exchangers or impinging cooling devices. However, despite the large number of devices that use this geometry, the expanded flow behaviour still needs further research to understand and predict the full system performance. This paper presents the application of the non-uniform finite difference approximation method developed in Sanmiguel et al. for the numerical characterisation of a confined swirling laminar jet discharging with a large expansion ratio. This investigation can be considered an extension of previous work by Revuelta, but now a swirling flow is generated by a rotating pipe upstream the expansion. The structures found when a fully-developed rotating Hagen-Poiseuille flow discharges into a much larger pipe section are summarised in a bifurcation diagram, whose coordinates are the Reynolds number of the jet (Rej) and the swirl parameter (L), for which the time-dependent, axisymmetric and incompressible Navier-Stokes equations are integrated numerically. For values of the jet Reynolds number below 200, there is a critical value of the swirl parameter above which stable vortex breakdown appears. For values of the Reynolds number above 200, three different behaviours are observed, and each performance appears for a critical value of the swirl parameter. When increasing the swirl parameter from zero, the flow becomes axisymmetrically unstable, showing an oscillatory behaviour. If further increasing the swirl intensity, the oscillatory flow coexists with a vortex breakdown bubble and, finally, a steady vortex breakdown is reached. The expansion ratio ε considered in all the simulations is 1 / ε = 20 . In previous literature, the exactness of the limiting critical Rej and L values that define these behaviours has been found to be influenced by the variability in the inlet profile conditions, which affects the expanded flow. This enhances the importance in the present investigation to accurately simulate the discharge pipe inlet profiles.
Simultaneous particulate matter and nitrogen oxide emission reduction through enhanced charge homogenization in diesel engines

In the presented study, low temperature combustion was established with a direct injection of diesel fuel being a representative of high reactivity fuels and tire py- rolysis oil being a representative of low reactivity fuels. Tire pyrolysis oil was tested as a potential waste derived fuel for low temperature combustion, as it features diesel-like physical properties and lower cetane number compared to diesel fuel. The goal of this study was determination of suitable injection strategies and exhaust gas re-circulation rates to explore potentials of both fuels in reducing emissions in low temperature combustion modes. It was demonstrated that rela- tively small changes in the engine control strategy possess the potential to significantly improve NO x /particulate matter trade-off with minor effect on engine effi- ciency. In addition, low temperature combustion was for the first time successfully demonstrated with tire pyrolysis oil fuel, however, it was shown that lower re- activity of the fuel is by itself not sufficient to improve NO x /soot trade-off compared to the diesel fuel as entire spectra of fuel properties play an important role in improving NO x /soot trade-off. This study thus establishes relations between different engine control strategies, intake manifold pressure and exhaust gas re -circulation rate on engine thermodynamic parameters and engine-out emissions while utilizing innovative waste derived fuel that have not yet been analysed in similar combustion concepts.
