Published: February 2022

This study determined the availability and utilization of physical facilities as correlates of students’ academic performance in electrical installation and maintenance work practice in technical colleges in Ekiti State. Four research questions and three null hypotheses guided the study. Descriptive survey and correlational research designs was used for the study. Eight hundred and fifty-three (818 students and 35 teachers) of electrical installation in the six government-owned technical colleges in Ekiti State were studied without sampling. The Instruments for data collection included checklist, structured questionnaire and performance test. The reliability of the performance test was determined through split-half technique. Spearman-Brown formula was employed for reliability coefficient computation which yielded a reliability coefficient of 0.905.  Percentage, mean, standard deviation and Pearson Product Moment Correlation coefficient were used to answer research questions. The t-test statistical tool was used to test the null hypotheses relating to utilization of instructional facilities while Pearson Product Moment Correlation coefficient was used to test the null hypotheses relating to physical facilities and students’ academic performance. Findings revealed that majority of physical facilities are available for electrical installation and maintenance work practice in technical colleges in technical colleges in Ekiti State.  The study also revealed that there is high positive relationship of 0.61 existing between students’ utilization of physical resources and their academic performances in electrical installation and maintenance work practice in technical colleges in Ekiti State. The study concluded that the level of availability and utilization of physical facilities for electrical installation and maintenance work practice in technical colleges in technical colleges in Ekiti State is not adequate for equipping students with practical skills for self-reliance. The study recommended among others that owners of technical colleges in Ekiti State should adequately provide relevant physical facilities for effective teaching of electrical installation and maintenance workshop practices.

Published: February 2022

A ansiedade é um fenômeno que pode ser caracterizado por sentimentos subjetivos de tensão, apreensão, nervosismo e preocupação que são experimentados por um indivíduo em um momento particular. O tratamento odontológico é considerado um dos que mais geram estado de ansiedade nos pacientes, por medo e por pensamentos preocupantes em relação aos procedimentos. A terapia endodôntica é uma das especialidades que mais causam temor e ansiedade. Foram entrevistados um total de 75 pacientes que se apresentaram na Clínica de Odontologia da Universidade São Francisco, para tratamento endodôntico, entre setembro e outubro de 2019, sendo 45 do sexo feminino e 30 do sexo masculino. O paciente foi caracterizado quanto ao gênero, idade, grau de escolaridade e renda familiar. Foram feitas perguntas quanto ao tempo decorrido desde sua última consulta ao dentista e sobre seu maior anseio em relação aos procedimentos odontológicos. Foram categorizados através de um questionário de ansiedade. O grupo do sexo feminino foi o que apresentou maior prevalência de ansiedade. Paciente considerados moderadamente e extremamente ansiosos somaram 24% da amostra, o procedimento que mais causou medo e ansiedade foi a anestesia (40%) e grande parte dos pacientes procuram tratamento odontológicos a cada 6 meses  (53,33%) . Com base nesses resultados podemos concluir que dentro da população estudada o nível de ansiedade entre mulheres se mostrou mais alto que em homens, e que a ansiedade ainda se mostra muito prevalente e deve ser sempre um fator a ser considerado e, desde que possível, minimizada no planejamento e pré-operatório do tratamento.

Autoproducción de los óleos alquídicos: formulación y propiedades
Authors: Espinosa González de San Pedro Mariano
Published: February 2022

Alkyd oils are a fairly recent type of paints, similar to traditional oils, yet with a faster drying time. Just because of its relative novelty, no pictorial techniques and materials handbook can be found which could show an artist how to produce their own alkyd oils, which indeed does happen with acrylics or traditional oils. The present study introduces a research that opens doors for an economic and accessible binder by means of which the artist can produce their own alkyd oil paintings. To this end, a wide sample of alkyd resins has been selected and they have been tested through several laboratory analyses and pictorial tests until a combination of alkyd resin and linseed oil, most perfectly suited to the objective of the research, has been found. Once this binder was found, it has been studied in depth by using it to produce paints with a wide range of pigments, and explaining both their individual formulation and their characteristics of Body and viscosity, Gloss, Texture, Flexibility and Drying. Finally, a palette with the most suitable pigments for self-producing alkyd oils has been proposed

KVIK Optimiser - An Enhanced ReaxFF Force Field Training Approach
Authors: Gaissmaier Daniel , van den Borg Matthias , Fantauzzi Donato , Jacob Timo
Published: February 2022

In this work, we demonstrate the superior exploration capabilities of the population-based methods over the sequential one-parameter parabolic interpolation (SOPPI) approach to optimise ReaxFF force field parameters. Evolutionary algorithms (EAs) are heuristic-based approaches using a population of concurrent models in the search space to evolve towards the global best through stochastic operations. The parallelisation of EAs scales almost linearly, and no differentiable objective function is required. These methods were tested for their search performance and convergence behaviour on different multi-dimensional, multimodal benchmark functions. The developed KVIK (Icelandic for: dynamic, in motion) optimisation framework features an extended training 1routine designed to parameterise solid-state systems efficiently. The optimisation routine was applied to train a reactive force field potential for metallic lithium and sodium and their interaction parameters. The KVIK-optimised ReaxFF potential function parameter set reproduces relative energy results from the density functional theory (DFT) reference data set within the standard deviation range established using the error estimation routine provided by the BEEF-vdW density functional. Finally, thermodynamically and kinetically driven surface growth phenomena on metallic Li- and Na-electrodes were investigated using coupled ReaxFF/Monte Carlo (MC) approaches.

Metal Matrix Composites are considered to be the center of research in materials due to their superior properties (mechanical as well as tribological) and applications. Hence, Tribological investigation of A356 (Si7 mg0.3 Fe0.2) alloy reinforced with Al2O3 nano particles (Avg <50nm) are studied and presented in this work. The specimens for the experimentation were prepared using Powder metallurgy route. Reinforcements were taken to be in concentrations of 0wt%, 2wt% and 4wt% and blended with the matrix. Tribological characterization was done with the use of Pin on Disc apparatus for varying load conditions (20, 30 & 40N) and speed conditions (400, 600 and 800rpm). Results clearly show that the rate of wear and frictionco-efficient is reduced by a larger extent due to the addition of Al2O3. Micrographs of worn surfaces showed the larger grooves which showed the material loss and it can be seen that the surface is less rough in the case of 4wt% reinforcement composite.
The Safekeeping of Being - A Leadership Responsibility
Authors:   , Harris Mark
Published: February 2022

Human existence is one entangled with technologies where humans attribute meaning, value and importance to technologies as they integrate them into their daily existence. Technology change frequently creates ethically potent circumstances requiring a response from leaders. This research considers how public-sector leaders might ethically guide existential technology change.

The research draws on selected ontological and phenomenological ideas in light of contemporary leadership thinking and public-sector leadership practice to develop a conceptual model. The model illustrates the uncertain, ambiguous and confused state that hinders leaders’ ability to guide technology change. Its central node is ontological ambiguity, which is probed further in order to provide a foundation for leaders to guide technology change.

The primary proposition is that contemporary leadership presents a diminished and disoriented position to the mediated relation humans have with technology and that an ontological perspective can help public-sector leaders who govern existentially-mediating technologies to overcome limitations in their practice.

Ambulance service use by patients with lower back pain: an observational study
Authors: Capsey Matt , Ryan Cormac , Alexanders Jenny , Martin Denis
Published: February 2022

Background: Lower back pain (LBP) is the leading cause of disability globally and can be distressing for patients. It is commonly reported that serious pathologies underlying LBP are rare and most patients would be more appropriately managed in primary care. However, recent literature
suggests patients accessing emergency care may differ from those accessing primary care. Currently, little is known about the use of ambulance services by people with LBP. The aim of this study was to investigate the extent and nature of ambulance services utilisation by patients presenting
with LBP.Methods: This observational study is a retrospective analysis of ambulance service calls in the North East of England presenting with LBP from 1 August 2016 to 31 July 2017 (Health Research Authority registration 17/WS/0216).Results: Of 484,495 answered calls,
3315 (0.7%) calls were categorised as initially presenting with LBP. Women represented 59% of callers. Most calls were from those aged 41‐50 and 71‐80 years old. Almost half of patients (48%) initially presenting with LBP were later categorised with a problem elsewhere. Of the
patients, 49% received analgesia, including Entonox (24%) and morphine (13%). Most patients (69%) were transported to an emergency department while 28% remained at home.Conclusion: LBP is a relatively common reason to call the ambulance service. Contrary to data from primary care,
non-spinal causes, which include medical emergencies, make up a significant proportion of this. Current guidance on back pain focuses on primary care and specialist settings. Future updates may need to consider emergency care as a distinct setting with a potentially different patient population.
An atypical presentation of orthostatic hypotension and falls in an older adult
Authors: Thoburn Steve , Cremin Steve , Holland Mark
Published: February 2022

Introduction: Falls are a significant cause of morbidity and mortality in older adults. Orthostatic hypotension (OH) is very common in this cohort of patients and is a significant risk for falls and associated injuries. We present the case of an 89-year-old female who fell at
home, witnessed by her husband. OH was identified during the clinical assessment and considered to be the predominant contributing factor, although the clinical presentation was not associated with classical symptoms.Case presentation: The patient lost balance while turning away
from the kitchen sink; she noted some instability due to a complaint of generalised weakness in both of her legs. No acute medical illness or traumatic injury was identified. A comprehensive history was obtained that identified multiple intrinsic and extrinsic risk factors for falling. The
cardiovascular examination was unremarkable except for OH, with a pronounced reduction in systolic blood pressure of 34 mmHg at the three-minute interval and which reproduced some generalised weaknesses in the patient’s legs and slight instability. Although classical OH symptoms were
not identified, this was considered to be the predominant factor contributing to the fall. A series of recommendations was made to primary and community-based care teams based upon a rapid holistic review; this included a recommendation to review the patient’s dual antihypertensive therapy.Conclusion:
It is widely known that OH is a significant risk factor for falls, but asymptomatic or atypical presentations can make diagnosis challenging. Using the correct technique to measure a lying and standing blood pressure, as defined by the Royal College of Physicians, is crucial for accurate diagnosis
and subsequent management. Ambulance clinicians are ideally placed to undertake this quick and non-invasive assessment to identify OH in patients that have fallen.

Abstract: Diabetes Mellitus is the disease which causes premature mortality, and the leading cause of  blindness, heart disease, and kidney failure in the world with increasing prevalance. Exercise is fundamental in Diabetes Mellitus management which functions to improve insulin sensitivity and control blood glucose level. A number of studies have been carried out to explore the effect of aerobic exercises on blood glucose level among patients with type-2 Diabetes Mellitus. The research aimed to evaluate the effect of aerobic exercise’s type, frequency, intensity and duration on blood glucose level among patients with type-2 Diabetes Mellitus. This study was systematic review. The literature searches were specified from 2005-2020 through Pubmed and Google Scholar. 40 studies in total based on specific criteria was included to this study. Thirty-nine out of forty studies revealed that a variety of aerobic exercises such as walking, gymnastic (diabetic, aerobic, foot, ergonomic), step test as well as static cycling give impact on lowering blood glucose level. Seventeen out of forty studies fulfilling the criteria of frequency, duration and intensity showed that exercise helps reduce blood glucose level. In conclusion, performing aerobic exercise regularly and appropriately helps to lower blood glucose level among patients with type-2 Diabetes Mellitus.

Home industries, especially at gold craftsmen in Malimongan Village, Makassar City, working indoors can experience pressure on hot and cold. In addition, the working period has been decades and used personal protective equipment are rarely used at gold craftsmen as protection from exposure of toxic in the work of environment. This study aims to analyze of humidity, temperature, working period, and used of personal protective equipment in home industry at gold craftsmen. This type of research is a descriptive survey. Direct collection was used a thermohygrometer, Samples of 30 houses, interviews through questionnaires at gold craftsmen amounted to 30 human sample were chosen using the simple random sampling. The analyzed using the frequency distribution of each variable. The results showed that the humidity in the room was mostly 66,7% not eligible requirements and 33,3% qualified requirements, an average of 62,90%. Most of the air temperature 86,7% not eligible requirements and 13,3% qualified requirements, an average of 32,430C. The working period at gold craftsmen >5 years is 96,7% and working <5 years is 3,3%, the working period between 3-32 years, an average of  15,57 years. Respondents never used of personal protective equipment such as face mask 93,3% and 6,7% sometimes used by towel for cover their nose. It is expected in home industry needs to increase ventilation in the workspace so that air of circulation can enter properly. In addition, at gold craftsmen need used of  personal protective equipment while working.

Pelatihan Solid State Fermentation (SSF) dedak untuk Menghasilkan Larva atau Belatung Lalat Tentara Hitam (Hermetia illucens) atau Black Soldier Fly (BSF) sebagai Pakan Unggas Alternatif di Desa Wonua, Kecamatan Konda, Kabupaten Konawe Selatan, Provinsi Sulawesi Tenggara, Indonesia telah dilakukan. Belatung BSF ini mengandung protein tingkat tinggi untuk pakan ternak. Dan desa Wonua ini adalah desa pertama di Sulawesi Tenggara yang telah diperkenalkan untuk menyediakan pakan unggas alternatif ini. Mayoritas masyarakatnya adalah petani dan sebagian merangkap sebagai peternak sapi dan unggas. Dengan ini, diharapkan bahwa produksi belatung dari BSF dapat menjadi populer dan menyebar di Sulawesi Tenggara (setidaknya tidak terlambat jika dibandingkan dengan popularitasnya di Jawa yang telah lebih dulu menarik perhatian banyak petani). Dalam kegiatan ini, kami memberikan bantuan teknis dan pelatihan tentang cara menghasilkan belatung BSF menggunakan dedak sebagai media untuk pertumbuhannya. Target keluaran yang dicapai adalah kemampuan petani tentang cara membiakkan dan memproduksi belatung secara mandiri. Selain itu, diharapkan para petani dapat membagikan pengetahuan ini yang tidak terbatas pada petani lain dari desa ini dan tidak memiliki kesempatan untuk mengikuti pelatihan ini tetapi juga kepada petani – petani dari desa-desa sekitarnya. Parameter yang digunakan untuk mengukur target output adalah jumlah peserta pelatihan dan pendampingan aktif, jumlah petani yang mampu menghasilkan belatung secara mandiri.

The work objective. Study of energy conditions for grinding ferromagnetic particles by non-contact method in devices with a rotating electromagnetic field.

The problem to which the article is devoted. Development of an energy model for controlling the process of grinding ferromagnetic particles of sludge wastes in a rotating electromagnetic field and experimental confirmation of its relevance.

Research methods. Theoretical studies are based on the main principles of the theory of magnetism, strength and destruction of solids. Experimental studies were carried out at the Research Institute of "Vibrotechnologii" of Don State Technical University using a pilot plant implementing a rotating electromagnetic field.

The novelty of the work. Establishment of analytical dependences describing the energy aspects of grinding ferromagnetic particles in a non-contact manner in devices with a rotating electromagnetic field.

The results of the study. A dependence is proposed that makes it possible to estimate the energy state of particles in a magnetic vibrating bed formed in devices under the influence of a rotating electromagnetic field. The energy condition determining the threshold value of the field induction gradient is established, which ensures a stable mode of the magnetic vibrating layer, and, as a consequence, grinding of particles to a given size. An energy model for controlling the grinding process of ferromagnetic particles of sludge wastes in a rotating electromagnetic field is developed and probability-theoretic formulas for estimating the duration of the grinding process is proposed.

Conclusions. The use of devices with a rotating electromagnetic field allows to implement effectively one of the important stages of treating metal sludge wastes associated with grinding of its ferromagnetic particles, which ensures the production of ferromagnetic raw materials with high granulometric characteristics.

The proposed energy model of particle grinding in a rotating electromagnetic field, based on the balance of the energy of destruction and the energy received by the particle from the electromagnetic field, taking into account the mechanical and magnetic characteristics of the material, makes it possible to implement the process of controlling the granulometric size of ferromagnetic particles of sludge wastes.
