Covid-19 cases are on the rise once again with Omicron variant sweeping through the globe. The effect on music education has never been poignant with schools closing down and face-to-face instruction halted in order to mitigate the effects of the highly transmissible variant. Given the current situation, studying piano in distance mode whether online, technology based such as using print, DVDs, among others forms, has prompted teachers and students to harness technological affordance in order to deliver optimal learning amidst learning disrup-tion. This paper discusses theoretical underpinnings, applications, challenges and recommendations of distance education as applied in piano pedagogy among piano students in University of Miami, Florida. While learning to play the piano is generally conceived as a face-to-face interaction between a student and teacher, 21st learning with the use of Information, Communication Technology (ICT) attests to the notion that technology based learning enhances deep learning-content interaction in self-directed learning (SDL) where a high degree of learning autonomy optimizes learning outcomes even with interdependence among students in a socio-constructivist setting as in the case of video conferencing conducted by a lecturer where a highly structured presentation diminishes dialogue between learner and teacher, increases transactional distance which signals autonomous learning to take effect. The use of Distance Education in Music Pedagogy is already being done in many institutions. The benefits of adopting technology based learning answer to challenges in 21st century learning where Information, Communication Technology (ICT) is critical in flexible learning where learning control is maximized by the student anywhere, anytime. In todayβs high uptake of internet tools and applications, piano peda-gogy adopts to changing platforms while delivering optimal result to aspiring pianists.
The study sought to have in depth understanding of how important the service eligibility results of learners with mild intellectual disability were to their parents and teachers in terms of placement in inclusive classes. In order to achieve this objective, a case study design was used. The sample size was 29 participants consisting of one Head Teacher, nine Class Teachers who taught the learners with mild intellectual disability in inclusive classes, ten parents of learners with mild intellectual disability in inclusive classes and nine learners with mild intellectual disability from grade one to nine. Typical case purposive sampling procedure was used to select the sample. Data was collected through interviews and non-participant observations. It was found that the service eligibility results were not only important to parents and teachers but also to the learners who were placed in the inclusive classes. Based on the service eligibility results, learners were able to be placed in inclusive classes and teachers were able to offer them individualized lessons using activities for daily living. However, some learners in the inclusive classes did not benefit from being placed in an inclusive class due to the fact that despite eligibility results showing that they needed individualized education plans, they were placed in overcrowded classes which compromised individual attention. Therefore, the study recommended that the school, teachers and parents adhere to the service eligibility results.

Adaptive filtering constitutes one of the core technologies in digital signal processing and has numerous application areas in science as well as in the industries. Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beam forming. Acoustic echo cancellation is a common occurrence in todayβs telecommunication systems. The signal interference caused by acoustic echo is distraction to users and causes a reduction in the quality of the communication. The method used in carrying this research work is known as the normalized least mean square. This focuses on the use of the combination of Finite impulse response digital filter and Normalized least mean square algorithms to reduce this unwanted echo, thus increasing communication quality. This research work further did some comparative analysis of Finite impulse response digital filter, Least mean square, Normalized least mean square. But the improved Normalized least mean square adaptive filter response obtained in this research work turns out to be a positive result, with the highest signal to noise ratio and lower mean square error at 0.2 steps and 25 filter size. We are also recommending this method to be used in noise elimination in hearing aids, electrocardiograph systems, communication industries and any area that requires noise cancellation. KEYWORDS: Adaptive Filter, Finite Impulse Response, Hearing Aid, Noise, Acoustic, Feedback, Low pass Filter, High pass Filter
Boiler treatment chemistry has been shown to be critical in maintaining clean heat transfer surfaces and minimizing corrosion in higher pressure industrial boilers. Monitoring boiler feed water contamination, especially iron and copper, from condensate leakage and upsets is a critical parameter required to maintain control parameters which promote passivation and clean heat transfer surfaces. Hydrogen analysis has also been shown to detect FAC (Flow Assisted Corrosion) and UDC (Under Deposit Corrosion) subsequently monitor corrective procedures. Hydrogen analysis remains the only dynamic continuous monitoring technique available for corrosion monitoring in feed water and boiler systems.

The use of alternative feeds is mostly done by using local feed raw materials that are easily available and usually in the form of waste that has not been utilized optimally. However, these local ingredients have limitations as the ingredients are still experiencing problems, namely the high content of crude fiber, low content of crude protein raw materials, low balance of amino acids, and the presence of anti-nutritional substances. This causes the need for processing local feed raw materials before being used as feed ingredients. Various ways of processing that can be done one of them physically and biologically to improve and improve the quality of feed ingredients. In general, physical and biological feed processing technology is able to produce products that have a simpler structure and are easier to digest than the original ingredients. Through the application of physical and biological feed processing technology, improvements and improvements can be made to the nutritional value of local feed raw materials so that they can be used optimally for fish feed raw materials.
This research was conducted in order to verify empirically the presence and effectiveness of the Community of Inquiry (CoI) model in an online class, EDDE 206 (Research in Distance Education), a course requirement in Master of Distance Education at the University of the Phil-ippines Open University. Results indicated strong interactive relationship among the independent variables (social, cognitive and teacher) following a non- significant difference among the means of the variables based on One Way ANOVA conducted. This result was consistent with the Community of Inquiry (CoI) model of educational experience as a result of the interaction of the three variables (Garisson, Anderson, and Archer, 2000). In establishing the effectiveness of the CoI Model, results indicated positive causal relationship between learning out-come as the dependent variable in the form of coded teacher replies and the three independent variables such that high presence of variables indicated high learning outcome and conversely low presence of variables indicated low learning outcome. The issue on effectiveness of CoI was dealt in the manner that interactive presence of the variables sufficed to say that profound impact occurred based on positive causal relationship.
Climate change is a global phenomenon that occurs due to human activities. Aware of the importance of environmental issues, especially the impact of climate change, the United Nations has formed multilateral cooperation, namely the UNFCCC (United Nations Framework Convention on Climate Change) to stabilize the concentration of greenhouse gases that trigger global warming. In its development, the UNFCCC succeeded in producing a new protocol and agreement that became an integral part of the UNFCCC, namely the Kyoto Protocol and the Paris Agreement. In Indonesia, efforts to mitigate the impact of climate change are to maintain mangrove and seagrass ecosystems on the coast through the development of Marine Protected Areas that can prevent the impact of problems due to climate change and coastal pollution, as well as maintain marine biota and coastal fishery areas.

The literature study focuses on autocratic leadership as a barrier to success in the workplace and other institutions where it is used. The study accomplishes this goal by reviewing and synthesizing the present scholarly literature on this burgeoning topic. The review was conducted by using the Web of Science academic search engines to identify papers from top publications in operations and management. Leaders in developing economy organizations have been reported to have an autocratic leadership style. This review is intended to remind leaders that authoritarian leadership, no matter what color it is painted, is a style of leadership that is generally despised by the people who lead in enterprises. The majority of the time, employees do not have a favorable work attitude. Leaders have mostly ignored employees by adhering to an out-of-date set of principles because they stuck to Theory X, whereas most employees would be more aligned with Theory Y. The different definitions proposed by researchers were emphasized and explored in this review. The advantages and disadvantages of utilizing an authoritarian leadership style were also discussed. It was found that using an autocratic leadership style to solve problems hinders the development of creative ideas; as a result, executives should learn to apply restraint while employing the technique in their organizations.

The goal of this work was the production and the characterization of activated carbon from the Gudali species bones. The calcination have been done in the presence of phosphoric acid for the production of animal activated carbon as new and eco-friendly adsorbent. A textural and structural characterization was performed during this work. With regard to the textural analysis, results reveal 0.2-5.0 mm, 1.50 %, 17.63 %, of 6.84 and the of 666.251 mg/g for sieve, residual moisture, residual moisture, pHzpc, iodine value respectively. A large exchange surface of our animal activated carbon which can reach 1045 m2/g. Thus, the adsorbent has a microporous surface. Concerning structural analysis, the elemental analysis and the different crystallized phases of the product adsorbent have been determined by semiquantitative X- ray and X-ray diffraction. It appears that the abundant chemical elements constituting the adsorbent are Ca (49.73%) and P (43.21%). From these analyses, it appears that the chemical formula of the product adsorbent is Ca10 (PO4)6 (OH)2. FTIR spectra of the adsorbent showed strong bands at 1023, 872, 724, 599 and 558 cm-1 due to the vibrations of PO43- groups from the natural constituent hydroxyapatite of bone. Bands ranging from 1454 to 1943 cm-1 indicate the presence of CκO, CκC and CκN groups contained in the bone matrix of the organic phase responsible. The SEM images show that the surface of the adsorbent has inhomogeneous shapes, irregular structure, different sizes and pores, with a very developed porosity. Laser particle size distribution gives information about the particle size distribution of the animal activated carbon of the Gudali species. The adsorbent has a volume average diameter of Herdan D [4.3] = 219.613 Β΅m, corresponding to the center of gravity of the volume distribution of our particles.
The use and disposal of lead-acid batteries are increasing every year. Several strategies for their treatment have been put in place, some for the recovery of materials and others for the regeneration of batteries. The latter, which has been practiced for a very long time, has been revolutionized, saving management of the battery parks and reducing harmful waste, although it does not seem to be valued. It is a perfect ecological alternative. The mismanagement of failed batteries can be toxic, threatening water, soil, and the atmosphere, and the health of humans in the profession and the surrounding populations. This study presents all the solutions for managing the faulty batteries that are ecological. A review of the different types of lead recycling methods was carried out, and an experimental survey was carried out in the field with different craftsmen blacksmiths, car mechanics, and companies to identify the different methods resulting from failures. Then, we modeled Petri networks to manage used batteries by highlighting all the possibilities of the recycling process and subsequently proposed a generic recovery of materials by craftsmen. This work is a new management of faulty lead batteries highlighting safely the various players in society in contact with these faulty batteries.
In this paper, we illustrate the design process and schematics of a new design of wireless-node port, having the ability to interface with sensors and actuators alike. It works on the principle of a master-slave network, with each node acting as a slave to the master connected to a cloudbased monitoring system. We focus on the design paradigms to develop a fully capable wireless-node. The aim is to have the designed node be as power-efficient as possible and have maximum configurability without the need of any form of hardware changes. Thus, the node needs to be able to be configured via code, while consuming minimum resources. An Embedded System was developed as a result, which uses an ATtiny85 microcontroller and nRF24L01 module for communication. A simple table of variables stored in the EEPROM of the microcontroller, can fully be modified to suit the type of operation needed by the device. The values of this table may be modified via RF communication from the master-node, thus making the same hardware design feasible and adaptable for both sensor networks, actuator network and even hybrid networks
