Investigation of heavy metals in water and sediment from contamination sites between Rimi and Kabawa axis, lower Benue River, Ibi, Taraba, Nigeria

This study investigated heavy metals in water and sediment from contamination sites between Rimi and Kabawa axis by Lower Benue River, Ibi, Taraba state. Heavy metal levels was investigated using atomic absorption spectrometer (AAS) Bulk Scientific Model 210 VGP using spectrometer techniques. The highest concentration of Zinc (Zn) in September/October, was (0.1667 mg/kg) while Cadmium (Cd) recorded a lower mean concentration value (0.0013 mg/kg) in December/January. Concentration ranking profile in water was found to be Zn>Pd>Cu>Cd. Results of heavy metal in sediments during the study from September 2022 to February 2023 revealed significant difference ( p <0.05) among metals studied. Ranking profile in sediment was found to be Zn>Pb>Cu>Cd. Zinc (Zn) value show the higher concentration (2.2667 mg/kg) in November and recorded lower value (1.1000 mg/kg) for the month of January and February. Value recorded for Cadmium (Cd) was observed to be lower than those recorded other metals. Higher Cadmium (Cd) values (0.0020 mg/kg) were observed to be high in September, October and January and low value (0.0013 mg/kg) recorded for November, December and February. Mean heavy metals concentrations between water and sediment during the study showed sediment recorded higher value for Zinc (Zn) (2.2667 mg/kg) in November while lower value was recorded for Cadmium (Cd) (0.0013 mg/kg) in November, December and January. Mean concentrations of metals on water showed zinc (Zn) reported higher in September (0.1667 mg/l), October (0.1667 mg/l), November (0.1334 mg/l) and December (0.1334 mg/l), compared to January and February (0.1000 mg/l). The concentration of Lead (Pb) in water recorded higher value in December (0.5147 mg/l), January, November (0.3910 mg/l), and February (0.3497 mg/l), compared to October (0.1647 mg/l), and September (0.1237 mg/l). Result of important physico-chemical parameters measured in water samples during the study period showed total dissolved solid (TDS) recorded the higher value (134.25 mg/l) compare to other parameters . There were significant difference ( p <0.05) in metals Variation between water and sediment. Findings from this study showed levels of metals were within WHO safe range and USEPA in drinking water and sediments except lead (Pb) values which was above the safe level. Thus, there is need for continuous monitoring of the contamination sites at Rimi and Kabawa districts by Lower River Benue and the general water body at large. If not controlled, it will contribute to general contamination of the river at Ibi and hinder its use for both commercial and household purposes.
CONTROL OF STRIP TENSION IN THE HEATING/COOLING SECTIONS OF CONTINUOUS ANNEALING LINES USING MODEL-BASED TENSION ESTIMATION

Continuous annealing lines are productive manufacturing lines used by steel making companies for the manufacture of thin steel sheet products. In these lines, the steel strip is continuously heated and cooled depending on the heat processing cycle required for a particular product. The heating/cooling cycle plays a critical role in programming the material properties of sheet products. The annealing furnace consists of several heat transfer sections, such as heating section, soaking section, rapid cooling section, and cooling section. By transporting the steel strip through the annealing furnace, concentrated uneven stress in the strip resulting from cold rolling process is relieved and new material property specifications, such as tensile strength, yield strength or ductile strength, are obtained. To improve transport behavior through the furnace, all the rollers are independently driven by a motor which are used to control strip speed and tension. Although rotational speed is measured for each driven roller shaft, tension measurement is spatially intermittent and located between any two heat transfer sections because of the inability to reliably measure tension within each heat transfer section. Since tension measurement is not available within the heat transfer sections, control of tension is challenging in these sections. An algorithm that provides tension estimation within each transfer section based on the model and tension measurements between each section is beneficial in regulating tension within acceptable levels in each section. In addition, due to heating/cooling of the strip during transport, changes in the physical and mechanical properties of the strip material must be accounted for in the design of tension control systems. In this paper, a dynamic model that provides the speed and tension behavior of the transported web through the heating or cooling section will be developed. Based on this model a tension observer will be designed for estimation of tension in each of the spans within the heat transfer
Seeking a Solution for Summer Reading Loss

The study was carried out to determine whether Turkish primary school 1st graders experienced reading loss during the summer holidays and whether giving book support to disadvantaged students during the summer holidays was effective in preventing this loss. The research was conducted with 26 students at a rural primary school. The pretest-posttest quasi-experimental design was used, and while the experimental group including 12 students carried out reading activities during the summer holiday as part of the ‘Telafide Ben De Varım’ (I Am in for the Remedial) program, the control group consisting of 14 students did not participate in any summer reading. In the study, the “Error Analysis Inventory” prepared by Akyol (2020) based on Harris and Sipay (1990), Ekwall and Shanker (1988) and May (1986) was used as the data collection tool. With the Error Analysis Inventory consisting of Comprehension Scale, Setting Scale, and Articulation Scale, three types of reading levels are measured: anxiety level, instructional level and independent level. The results of the pre-test administered before the start of the summer vacation using this inventory revealed that the students in both groups generally showed poor reading performance and their average reading level was at the “anxiety” level. The post-test administered after the opening of the schools showed that the level of the control group did not change, while the experimental group increased to the “instructional” level. As a result of book reading activities, the reading level scores of the experimental group increased significantly compared to before the intervention, while there was a significant decrease in the control group. Based on these findings, the importance of providing book support to students living in disadvantaged areas to prevent summer reading loss and increasing book reading during the summer is strongly recommended.
Three-Dimensional Snow: How Snow Really Looks Like

The three-dimensional structure of snow is difficult to see, because ice is highly transparent in the visible spectrum. An improved method of the reconstruction and visualization of snow structures has been developed. Using this method, the three-dimensional structure of snow samples with a sidelength of 1 to 30 mm can be reconstructed and visualized on the computer. Samples from all snow types have been reconstructed. In addition, also a few samples of layer interfaces have been investigated. 3-D reconstruction clearly shows the structural instability of such interfaces.
The Stock Market Channel of Monetary Policy Transmission Mechanism in Nigeria

The Nigerian financial sector is undergoing some fundamental reforms. These reforms have brought with it increases in the number of financial variables and increased participation of ordinary citizens in the economy, more especially in the stock market. The nature and level of economic activities in the economy have increased and the stock market is poised to play an increasing role as the financial sector reform takes hold. In order to achieve the goals of financial deepening and sustainable development, monetary policymakers need to pay attention to the impact of policy action on the activities of the Nigerian Stock Exchange. Using monthly data and VAR and ECM, economic methodologies, the stock market reactions to monetary policy decision were examined in this paper. The conclusion is that while the stock market is still at the developmental stage, Monetary Policy Rate (MPR) was found to have a negative and significant effect on the activities of the Nigerian Stock Market by impacting liquidity and credit conditions. Thus, Central Bank’s monetary policy rate can be used to send signals to stock market investors, and, therefore, acts as a good anchor in the economy.
SSR-based molecular diagnosis for Taiwan tea cultivars and its application in identifying cultivar composition of the processed tea

Taiwan specialty teas are produced with distinct manufacturing processes from specific cultivars of tea plants in Camellia. Due to the widespread transplantation of Taiwan tea cultivars and active international trading of tea materials, an accurate and reliable method to identify tea cultivars at the border is vital to protect the image of premium Taiwan specialty teas. In this study, we introduced the Taiwan Tea Variety Identification (TTVID) kit, a capillary electrophoresis-based multiplex PCR assay consisting of 12 simple sequence repeat (SSR) markers. A database composing these 12 SSR loci genotypes in 144 cultivars was established for marker assessment and molecular diagnosis. The power of discrimination on a locus ranged from 0.7894 to 0.966 and the combined match probability of 12 SSR loci was 5.34e-14. Cultivar pairwise comparison among 144 accessions showed that over 90.6% of the pairs had differential genotypes on at least 10 of 12 SSR loci. Further assessment showed that the TTVID kit could unambiguously recognize the cultivars mixed in the loose-leaf teas processed with various degrees of fermentation and roasting. Our results suggested that this TTVID kit effectively identified cultivar composition in loose-leaf tea and is helpful for border control in preventing adulteration and fraud in the Taiwan tea market.
What’s in My Toolkit? A Review of Technologies for Assessing Changes in Habitats Caused by Marine Energy Development

Marine energy devices are installed in highly dynamic environments and have the potential to affect the benthic and pelagic habitats around them. Regulatory bodies often require baseline characterization and/or post-installation monitoring to determine whether changes in these habitats are being observed. However, a great diversity of technologies is available for surveying and sampling marine habitats, and selecting the most suitable instrument to identify and measure changes in habitats at marine energy sites can become a daunting task. We conducted a thorough review of journal articles, survey reports, and grey literature to extract information about the technologies used, the data collection and processing methods, and the performance and effectiveness of these instruments. We examined documents related to marine energy development, offshore wind farms, oil and gas offshore sites, and other marine industries around the world over the last 20 years. A total of 120 different technologies were identified across six main habitat categories: seafloor, sediment, infauna, epifauna, pelagic, and biofouling. The technologies were organized into 12 broad technology classes: acoustic, corer, dredge, grab, hook and line, net and trawl, plate, remote sensing, scrape samples, trap, visual, and others. Visual was the most common and the most diverse technology class, with applications across all six habitat categories. Technologies and sampling methods that are designed for working efficiently in energetic environments have greater success at marine energy sites. In addition, sampling designs and statistical analyses should be carefully thought through to identify differences in faunal assemblages and spatiotemporal changes in habitats.
Journal of Technology Education

Entry-level technology studies in architecture often baffle first-year university students, and academic staff in turn tend to resist teaching foundational studies in the technology of design (ToD). ToD has often been considered “high risk,” as evidenced by a high proportion of dropouts and retakes, and has been deemed the least preferred subject among both students and academics. Based on activated awareness of design as a mode of pedagogy, the new learning design transformed technology education, enabling students to learn through technology interaction instead of theory recitals and memory testing. The improved undergraduate ToD unit took on the form of a project hub, and the technology that students studied was immersive and hands on. This new learning design utilized real-world occurrences. When students could apply concepts and gain a clear grasp of their principles, learning outcomes became spontaneous. Design activism, which was conceptualized in the six-course meal model, built excitement around learning and assignment tasks. Backed by established learning and teaching concepts such as the controlled guidance procedureand scenario-based learning, the ToD unit achieved increased student performance by reducing effort, inhabiting learning, and facilitating memory retention. The increased performance and retention rates among students demonstrated that design activism can help students approach learning via cyclic deductive–inductive learning routes with multiple entry points.
Journal of Technology Education

Technology and engineering education is filled with so many varied topics that it is almost impossible to break them into grade-level courses. As a result, courses are often mixed with all grade levels and all types of learners. On rare occasions, one course section pops into the schedule that is all one level. When this occurs, it may become necessary to reevaluate the practices that have been implemented in the classroom related to instruction, discipline, and policy. For this study, the population of graphic design students consisted of primarily freshman students. In this case, the researcher was faced with an entire section of graphic design with primarily freshman students. In the past, there had been freshmen mixed into other sections without any problems. However, this class posed an interesting problem: traditional instructional methods were not working. This section of mostly freshman students was falling behind the usual curricular pace for the class. They were struggling to work with the independence that they are granted as high school students. They were also struggling with following the directions given to them in the manner traditional for this course, which was backed by past practices. With this new demographic, it became necessary to evaluate alternative instructional practices in relation to freshman students. The typical collegiate style in which instruction has been given in my classroom has been successful in the past. However, this approach, in which all expectation is put on the learner, was not proving successful in a classroom filled primarily with freshmen students who have not fully made their transitions out of middle school mentality. Therefore, I decided to look into scaffolded instructional models as a means to increasing student understanding and mastery.
Testing campaign slogans designed to motivate older people to be more physically active.

Objectives and importance of study: Being physically active is critical for healthy ageing, yet many older people do not meet physical activity guidelines. The aim of this study was to test the relative effectiveness of five previously identified campaign slogans designed to encourage older people to be more physically active: 'Be active 30-60 minutes a day to stay fit and well'; 'Move more, live longer'; 'Stay fit to stay functional'; 'This is your time - enjoy being strong and active'; and 'Use it or lose it'. STUDY TYPE Online experiment Methods: A total of 1200 Australians aged 50 years and older (50% female, mean age 65 years) were recruited to complete an online survey, with respondents randomised to answer a series of questions on a video featuring one of the five slogan conditions. One-way ANOVAs with Tukey's post-hoc tests were used to identify differences in outcomes between slogans. RESULTS Overall, the slogans were assessed favourably, suggesting older adults may be receptive to messages about increasing their physical activity. 'Use it or lose it 'performed best across the outcome measures of internal and external motivation, perceived effectiveness, liking, believability, and personal relevance. CONCLUSION Efforts to encourage physical activity among older Australians could use the slogan 'Use it or lose it' as an evidence-based tagline.

UvA-DARE Political relevance in the eye of the beholder: Determining the substantiveness of TV shows and political debates with Twitter data

Addressing the call to move beyond a simple genre classification of TV shows as either substantive (hard) news or non-substantive (soft) infotainment, we propose using social media reactions to determine a program’s political relevance. Such an approach provides information that goes beyond genre or content characteristics and reflects what really reaches an audience. Analyzing tweets about two Dutch talk shows and four U.S. primary debates, we show that audience responses to television programs differ considerably regarding their political relevance. Thereby, we demonstrate how examining online audience reactions can be employed as a sophisticated and valid way to assess the political relevance of TV programs. coverage in traditional media.
