Upper secondary students’ situational interest in physics learning in Finland and Chile

ABSTRACT This study examines how classroom activities, student gender and student personal interest in science studies and careers predict situational interest in physics learning. Teaching modules were designed based on the secondary physics curricula in Finland (Helsinki) and Chile (Santiago and Viña del Mar) emphasising students engagement in scientific practices. The study was implemented in four classrooms in both countries. Data on situational interest and ongoing classroom activities were obtained using the experience sampling method, with measurements taken three times during a lesson. The process yielded a total of 1717 measurements in the Finnish schools and 1767 in the Chilean schools. Multilevel regression analyses with mixed effects and random intercept were conducted. Results showed a positive effect of scientific practices that required asking questions, designing scientific inquiry and interpreting data on situational interest. Student collaborative situations were more interesting for Chilean students than for Finnish ones. In terms of gender differences, on average, Finnish male and female students experienced the same level of situational interest, while the situational interest of Chilean female students was higher than the average of male students. Personal interest in science studies and careers was the best predictor of situational interest in both countries.
Transcriptome Profiling of Cu Stressed Petunia Petals Reveals Candidate Genes Involved in Fe and Cu Crosstalk

Copper (Cu) is an essential element for most living plants, but it is toxic for plants when present in excess. To better understand the response mechanism under excess Cu in plants, especially in flowers, transcriptome sequencing on petunia buds and opened flowers under excess Cu was performed. Interestingly, the transcript level of FIT-independent Fe deficiency response genes was significantly affected in Cu stressed petals, probably regulated by basic-helix-loop-helix 121 (bHLH121), while no difference was found in Fe content. Notably, the expression level of bHLH121 was significantly down-regulated in petals under excess Cu. In addition, the expression level of genes related to photosystem II (PSII), photosystem I (PSI), cytochrome b6/f complex, the light-harvesting chlorophyll II complex and electron carriers showed disordered expression profiles in petals under excess Cu, thus photosynthesis parameters, including the maximum PSII efficiency (FV/FM), nonphotochemical quenching (NPQ), quantum yield of the PSII (ΦPS(II)) and photochemical quenching coefficient (qP), were reduced in Cu stressed petals. Moreover, the chlorophyll a content was significantly reduced, while the chlorophyll b content was not affected, probably caused by the increased expression of chlorophyllide a oxygenase (CAO). Together, we provide new insight into excess Cu response and the Cu–Fe crosstalk in flowers.

Numerical Modeling, Simulation and Evaluation of Conventional and Hybrid Photovoltaic Modules Interconnection Configurations under Partial Shading Conditions

Partial shading on solar photovoltaic (PV) arrays is a prevalent problem in photovoltaic systems that impair the performance of PV modules and is responsible for reduced power output as compared to that in standard irradiance conditions thereby resulting in the appearance of multiple maximas on panel output power characteristics. These maxims contribute to mismatch power losses among PV modules. The mismatch losses depend on shading characteristics together with different interconnected configuration schemes of PV modules. The research presents a comparative analysis of partial shading effects on a 4 x4 PV array system connected in series(S), parallel (P), serries-parallel (SP),total-cross-tied (TCT),central-cross-tied(CCT),bridge-linked(BL),bridge-linked total cross-tied (BLTCT) ,honey-comb(HC), honey-comb total-cross-tied (HCTCT) and ladder (LD) configurations using MATLAB/Simulink. The PV module SPR-X20-250-BLK was used for modeling and simulation analysis. Each module is comprised of 72 number of PV cells and a combination of 16 PV modules was employed for the contextual analysis. Accurate mathematical modeling for the HCTCT configuration under partial shading conditions (PSCs) is provided for the first time and is verified from the simulation. The different configuration schemes were investigated under short-narrow,short-wide,long-narrow,long-wide, diagonal, entire row distribution, and entire column distribution partial shading condition patterns with mathematical implementation and simulation of passing clouds. The performance of array configurations is compared in terms of maximum power generated ), mismatch power loss (∆), relative power loss ) and the fill factor (FF). It was inferred that on average, TCT configuration yielded maximum power generation under all shading patterns among all PV modules interconnection configurations with minimum mismatch power losses followed by hybrid and conventional PV array configurations respectively.

Percussion‐based bolt looseness identification using vibration‐guided sound reconstruction

Bolted connection functions to fasten and secure parts together for engineering structures. Newly developed percussion‐based approaches have been proven as a fast and effective tool for bolt looseness identification; however, most of the existing studies use machine learning assisted approaches to classify percussion sounds and predict looseness conditions without investigating the relationship between percussion sounds and bolt vibrations. This paper presents a conceptual research to utilize bolt vibration signal to reconstruct percussion sounds, which significantly improves the validity and accuracy of bolt looseness identification. In the experimental study, a laser Doppler vibrometry was used to capture vibrational information of the test bolt; meanwhile, percussion sounds were collected by microphones. The relationship between sound and vibration signals was investigated using wavelet packet decomposition and correlation analysis. A new set of sounds were reconstructed by combination of the sound packets which showed the strongest correlation with the vibration signal. The reconstructed sound database was then transformed into spectrograms and trained by a two‐dimensional convolution neural network to identify bolt looseness conditions.

BACKGROUND: A report from the West Sumatra Provincial Health Office in December 2017 showed increase in the percentage of overweight and obese children in the city of Padang. In 2014, overweight children amounted to 4.86% and an increase in 2016 to 6.44%. AIM: This study aimed to determine the most dominant risk factors affecting the incidence of obesity in adolescents in Padang City. MATERIALS AND METHODS: This study was conducted on 484 respondents from 4 (four) schools, namely SMPN 26, SMPIT Adzkia, SMAN 3, and SMA Adabiah Padang in December 2019-February 2020. Data analysis used the Chi-square test and multiple logistic regression tests. RESULTS: The multivariate analysis results showed that adolescents’ eating behavior variable was the most dominant factor affecting adolescents’ incidence of obesity with a significance value of p < 0.05 and Exp (B) 14.11. These results showed that adolescents who behave eat poorly at 14.11 times, have the risk of obesity more than adolescents who eat well. CONCLUSIONS: Adolescent eating behavior variables can predict the incidence of obesity in adolescents together with adolescent physical activity variables, adolescent attitudes, and adolescent knowledge.
Design of unknown input observer for discrete time nonlinear generalized Markov jump systems under fault conditions

In this paper, the design problem of unknown input observer for a class of nonlinear discrete time Markov jump systems has been studied. The state equation of the system with unknown input and actuator faults is considered. The unknown input observer has a relatively novel structure and can be applied to nonlinear discrete time Markov jump systems to estimate the system state and fault at the same time. Second, the design feasibility conditions of the unknown input observer based on Lyapunov function are given. Furthermore, the conditions are transformed into a set of linear matrix inequality conditions, which can be used to solve the parameters easily by using the related software toolbox. Finally, an example of nonlinear tunneling diode circuit is given to verify the feasibility and effectiveness of the proposed method.

A novel scaly N‐doped carbon/Mo‐doped TiO2 composite to regulate polysulfides for excellent‐performance lithium‐sulfur batteries

Lithium‐sulfur batteries with a high energy density have got eye‐catching attention for next‐generation energy storage systems. However, their practical application is impeded by the lithium polysulfide shuttle effect causing rapid capacity fading. Herein, a novel scaly N‐doped carbon/Mo‐doped TiO2 (N‐TiO2@Mo) composites as sulfur‐wrapping host for lithium‐sulfur batteries are prepared. This host not only can physically adsorb polysulfides due to the unique scaly carbon structure with a rough surface and large specific surface area, but also chemically adsorb polysulfides and effectively inhibit the shuttle effect from the Ti‐O bond. As cathode for lithium‐sulfur battery, 0.2 N‐TiO2@Mo/S shows a high‐capacity maintenance (70.41%, 83.97%, and 95.04% after 30, 50, and 50 cycles at 0.2, 0.5, and 1 C) and a low‐capacity degradation (0.091% per each cycle for 200 cycles). Moreover, the cathode delivers a smallest voltage gap (0.18 V) between oxidation and reduction plateaus and a high Qlow/Qhigh (2.43 at 0.1 C). This work offers a promising avenue and provides a new guide to high‐performance lithium‐sulfur batteries.
Nitrogen Release in Soils Amended with Different Organic and Inorganic Fertilizers under Contrasting Moisture Regimes: A Laboratory Incubation Study

Understanding nitrogen (N) release patterns and kinetics is a key challenge for improving N use efficiency in any agroecosystem. An incubation experiment was done to study the N release pattern and kinetics of contrasting soils amended with compost (CO), poultry manure (PM), rice husk biochar (RHB), poultry manure biochar (PMB) and cowdung (CD) combined with chemical fertilizer (integrated plant nutrient system, IPNS approach) under two moisture regimes, viz. field capacity (FC) and continuous standing water (CSW) at 25 °C for 120 days. Our results revealed that NH4+-N was the dominant under CSW conditions, whereas NO3−-N was dominant under FC conditions. Net mineral N data fitted well to the first order kinetic model. Both N release potential (N0) and rate constant (k) were greater in acidic soil than those of charland soil. The maximum N release varied between 24.90–76.29% of input depending on soil type and moisture status. N mineralization was strongly correlated with urea N application. PM and PMB mineralized in all soil and moisture conditions whereas N immobilization was observed in the case of RHB. N mineralization was strongly correlated with urea N application. Gaseous N losses were different for the organic amendments exhibiting more gaseous N losses in PM, CD and CO based IPNS whereas the lowest gaseous N loss was observed in PMB based IPNS. Biochar based IPNS increased soil pH in all conditions. Thus, the present study suggests that N release depends on soil type, soil moisture and type of organic amendment. However, CO, PM and CD based IPNS can be recommended for both acidic and charland soils in terms of N release as short duration crops will suffer from N deficiency if biochar based IPNS is used in the field.
Large wild herbivores slow down the rapid decline of plant diversity in a tropical forest biodiversity hotspot

1. The UN declaration of the Decade of Ecosystem Restoration 2021– 2030 emphasizes the need for effective measures to restore ecosystems and safeguard biodiversity. Large herbivores regulate many ecosystem processes and functions; yet, their potential as a nature-based solution to buffer against long-term temporal declines in biodiversity associated with global change and restore diversity in secondary forests remains unknown. 2. By means of an exclusion experiment, we tested experimentally the buffering effects of large wild herbivores to avert against long-term biodiversity collapse in old-growth and secondary tropical forests in the Atlantic Forest of Brazil where sapling abundance and species richness declined c . 20% over the course of 10 years. The experiment comprised 50 large herbivore exclosure-open control plot pairs (25 at the old-growth forest and 25
A Feature Analysis Based Identifying Scheme Using GBDT for DDoS with Multiple Attack Vectors

Therefore, improving the ubiquitous detection capability of DDoS attacks and accurately and quickly identifying DDoS attack traffic play an important role in later attack mitigation. This paper proposes a method to efficiently detect and identify multivector DDoS attacks. The detection algorithm is applicable to known and unknown DDoS attacks.
The Impact of Education in Combating the Development of the Trafficking in Human Beings Process

This research will discuss the impact of education on combating the development of the process of trafficking in human beings, as a growing phenomenon in Kosovar society. Trafficking in human beings is a violation of fundamental human rights, a negative phenomenon, as well as a concern and a danger to the whole society. Kosovo is a country in transition, where trafficking in human beings is a great challenge to Kosovar society, especially bearing in mind that this phenomenon developed in the post-war years in Kosovo. The phenomenon of trafficking in human beings dates back to the early days of humanity (from the slave-owner society), but now the forms and patterns of trafficking have changed, transforming into "modern slavery". This phenomenon has become a concern of Kosovar society, which is constantly making great (institutional) efforts to combat this phenomenon. Among the most relevant factors for combating trafficking in human beings is education as a basic factor of a healthy society, which shapes the personality of young people and builds the foundations of a vital society which builds its future on social values and fights trafficking with human beings. Thus, the role of education in a society, as well as the path towards combating the process of trafficking in human beings is analyzed by: family, education, social circle, tradition, community culture, state policies and other competent accompanying institutions. The thesis of this research will be: How does education impact on the fight against the evelopment of the process of trafficking in human beings in Kosovo society? Many authors have given different opinions about education as a factor in combating trafficking in human beings and its impact on society, which will be discussed below. Thus, the paper tends to concretize the impact of education on prevention of trafficking in human beings, where the interview method was used, which was conducted with the competent education officials. As a result of a country with a low level of economic development, high level of poverty, inadequate quality of education, shortcomings in social policies, dysfunctional level of legal infrastructure, we conclude that all these influential factors in combating the phenomenon of trafficking with human beings, remain a constant task for their improvement in our society.
Repositioning Organizational Failure Through Active Acceptance

This paper considers the way organizations respond to failure by actively repositioning the failed outcome as success. When an organization fails to meet planned goals, they do not necessarily learn from the experience, automatically terminate the plan, or persist with the failing course of action. Instead, another response is to shift original aspirations by recasting what was achieved, acting as if the ensuing failure is positive, despite indicators suggesting otherwise. As a mode of organizational interpretation, this repositioning reformats the criteria for what is success in order to move forward, enabling organizations to continue failed outcomes and their tasks that are well past their use-by date. After detailing this adjustment, we model an active-acceptance protocol on failure, discussing whether organizational effectiveness is predictable from how firms respond to failure in this way. The paper fills a gap in dialogue specific to failing by opening an alternative path to understand how organizations frame failure differently.
CARDIO-PULMONARY RESUSCITATION: KNOWLEDGE AND COMPETENCIES OF CHARGE NURSES WORKING IN PUBLIC HOSPITALS

Cardiopulmonary resuscitation (CPR) is an emergency procedure performed in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. This study was carried out to explore the existing knowledge & skills of charge nurses working in public hospitals about cardio pulmonary resuscitation. A cross-sectional descriptive study was performed at the Nursing Department University of Health Sciences Lahore. One hundred charge nurses participated in this study. A self-administered structure questionnaire and observational check list were used to collect data from the study participants. A self-developed questionnaire containing 22 questions was distributed to the nurses and the filled questionnaires were analyzed as per the study objectives. A correct response was given a score of ‘1’ and the wrong responses were given a score of ‘0’. Resuscitation skills were tested by using the Anne manikin. The manikin was placed supine during the test. Statistical Package for the Social Sciences (SPSS) version 20 was used for data analysis. The result was summarized by using both descriptive (frequencies and percentages, graphs, mean + SD etc.) and inferential (chi-square) statistics. The mean± SD of the overall total knowledge scores was 9.67 ± 2.22 (the maximum possible score was 22). Mean skill score is 10.04 and standard deviation is ± 2.52 (the maximum possible score was 16). There was no significant association between the knowledge scores and skill scores. From the finding, it was concluded that the majority of the nurses’ knowledge was found poor while skill is fair. It is recommended that CPR training programs should be implemented in all hospitals and nursing schools. Refresher courses should be arranged in periodic basis. Those nurses who are trained in providing CPR repetitive periodic CPR training sessions should be arranged to update their knowledge and skill.
