Geochemistry and Mineralization of Some Selected Pegmatite Deposits in Panda North Central, Nigeria
Authors: Tanko I. Y. , Chime P.
Published: February 2022

Pegmatite constitutes an important lithologic unit in the Precambrian Basement Complex of Panda north central Nigeria. The primary aim of this study is to present a geochemical data of various rock types in the area especially pegmatite in order to determine their geochemical classification and mineralization potential of some selected pegmatite deposits in the area. Geochemical analysis reveals that the pegmatite samples have high SiO2 content; 73.8-94.8 wt%, low Na2O/K2O ratio suggesting they are strongly peralkaline and peraluminous, indicating that the pegmatite may have formed from mixed plutonic sources. The discrimination diagram of TiO2 versus SiO2 shows that the samples plotted on both igneous and sedimentary field, but majorly on the igneous field which is an implication that substantial material may have been generated from igneous sources. Also the plotting of the pegmatite samples in both the tholeiitic and calc-alkaline fields shows that the magma from which the rock was formed was not totally restricted in occurrence only to subduction related environment but also from the oceanic crust of calc-alkaline environments. This is further confirmed by discrimination diagrams plot of TiO2-K2O-P2O which indicates that substantial samples plotted fall within the continental crust. High potash content alkalies with relative Fe-enrichment and silica suggest the plutonic generation of magma and the development of the rocks in both the oceanic and continental crust. Major elements analysis of both the granitic rock aplite and biotite gneiss shows moderately high silica values. These values reflect the geochemical characteristic of crystalline rocks. The pegmatite of the study area exhibits low contents of Nb, Ta, Ga, Rb and Sn which are the major mineralization indices for pegmatite bodies. In classifying the pegmatites, rare metal indicative elements were used to discriminate the barren ones from the mineralized. A plot of Ta-Ga reveals that all the samples plotted are below the boundary of mineralization line, suggesting all the pegmatite samples in the study area to be barren in term of rare earth metals and can be compared to other pegmatite bodies in Nigeria and around the world.

Authors: Kajtazi Besime Sh. , Floqi Tania
Published: February 2022

Kosovo’s waters are unevenly distributed in time and space. Kosovo is water scarce, and it also has the low level of water resources development and storage. In particular Iber basin is water stressed, but in the next 20 years it is expected that all Kosovo’s basins will be water stressed [1]. This is due to population and general economic growth, and resource variability. The anticipated revitalization of the irrigation and mining sector and additional demands from the energy sector will increase pressure on new water demands [5]. For these reasons, the water quality of existing resources will become an ever-growing problem if not addressed now. The lignite-fired power plant “Kosovo B” is main the energy source in the country. The wastewater produced from its operation is discharged into Sitnica river with minimum treatment. With study of pollution level of wastewater discharges, this article sets several recommendations for treatment of wastewater in order that power plant meets national and EU operation requirements.

Authors: Okafor I. T. , Osarenmwinda J. O. , Onifade M. K.
Published: February 2022

Oblique metal cutting is a milling process which constitutes the work piece, tool piece, machine centre and the machinist or operator. This research has been able to obtain some responses such as tool life, and the surface roughness. Most machine elements fail due to some poor surface finish errors such as craters, waviness, flay and lay. Previous researchers have focused more on the absolute value of the surface roughness (Ra) and this cannot provide for all the errors encountered on surface texture. The primary aim of this research is to develop models that can predict the surface roughness of machine parts produced in oblique metal cutting above the absolute value of the average surface roughness and in turn provide a document or framework for machinist which can serve as a guide for machinist. The work has been able to determine a near perfect surface roughness for mild steel using coated carbide as tool piece as the models developed has minimized the effect of surface roughness at run 6, 6 and 8 for Ra, Rz and maximized TL in the values of 1.071408 micrometer, 2.668293 micrometer and 49837238 seconds respectively. Also. the analysis of variance performed has also shown that is proper to accept the analysis using a significance ? level of 0.05.

The design & development of automated chair is done in the project for the Excavator machine to ensure the comfort of the rider ensured for any angle of work being carried out by the excavator. The various components like the chair, support rod, rod end eye bearing, the control valves for the flow, pressure and direction, hose pipe and hydraulic cylinder are used to make the model of the automatic chair. The various electronic components like the proximity sensors, relays and SMPS are utilized to control and regulate the incline and decline of the chair as per the machine’s inclination so that horizontal position of the chair can be attained. The part designing and the assembly of all components are conducted in CATIA software. The circuit diagram for the proximity sensor is also made. The model is fabricated using the tools and equipment like the gas cutter, grinding machine, bending machine etc. The prepared model is tested for the incline and decline of the chair at 20? angle using the real-life working parameter of the machine. From the test the chair is observed to properly attain the horizontal position along with actuation of hydraulic cylinder by making sure that operator’s centre of gravity is maintained to ensure the comfort of rider.
Some Engineering Properties of Foamed Concrete for Sustainable Technological Development
Authors: Oginni Felix A. , John Samuel N.
Published: February 2022

A study of the technology of foamed concrete production is carried out. The engineering properties and applications of this type of concrete are presented for varying densities so as to effectively tap the advantages of its use for specific purposes. The properties considered are the 7-day compressive strength, thermal conductivity, modulus of elasticity and drying shrinkage. A study of the behaviours of foamed concrete at varying dry densities for the different characteristics was undertaken. Results indicate that as the dry density increases, the engineering properties increase though at different rates for the 7-day Compressive strength, Thermal conductivity, and Modulus of elasticity. The drying shrinkage decreases as the dry density increases. A comparative study of the 7-day Compressive strength and Modulus of elasticity show that they both follow the same trend over the varying dry density except at a dry density of 1200 kg/m3. A comparative study of the thermal conductivity and the percent drying shrinkage indicate that the thermal conductivity is inversely proportional to the percent drying shrinkage. Economics and other considerations together with its multipurpose applications of foamed concrete can open up business opportunities in Africa and sustainability. This can also help in providing needed funds for infrastructural development.

Published: February 2022

With the rapid increasing bandwidth demand mainly driven by the development of advanced broadband multimedia application, such as video-on-demand (VoD), interactive high-definition digital television (HDTV) and video conference, new access network solutions that provide high capacity are highly needed to satisfy these emerging services. In a largely populated and technologically exposed institution such the University of Port Harcourt, this demand is truly great. The Passive Optical Network (PON), which utilizes the Fibre Optic Technology, is a suitable solution to this problem. Hence this is geared towards the design and simulation of a Passive Optical Network for the University’s campus district. This Campus based Local Area Network consists of the Various Faculty buildings, the Senate building which is the central administrative building, and was centralized at the Information and Communication Technology Center (ICTC), which served as the Central Office of the network. The Wavelength Division Multiplexing (WDM) technique was utilized because of its dedicated bandwidth for each subscriber and more flexible bandwidth management. The validation was carried out on a virtual computation environment called OptiSystem©.
Statistical Analysis of Electric Power Distribution Grid Outages
Authors: Diamenu Godwin
Published: February 2022

Power systems in general supply consumers with electrical energy as economically and reliably as possible. Reliable electric power systems serve customer loads without interruptions in supply voltage. Electric power generation facilities must produce enough power to meet customer demand. Electrical energy produced and delivered to customers through generation, transmission and distribution systems, constitutes one of the largest consumers markets the world over. The benefits of electric power systems are integrated into the much faster modern life in such extent that it is impossible to imagine the society without the electrical energy. The rapid growth of electric power distribution grids over the past few decades has resulted in a large increment in the number of grid lines in operation and their total length. These grid lines are exposed to faults as a result of lightning, short circuits, faulty equipment, mis-operation, human errors, overload, and aging among others. A fault implies any abnormal condition which causes a reduction in the basic insulation strength between phase conductors or phase conductors and earth, or any earthed screens surrounding the conductors. In this paper, different types of faults that affected the electric power distribution grid of selected operational districts of Electricity Company of Ghana (ECG) in the Western region of Ghana was analyzed and the results presented. Outages due to bad weather and load shedding contributed significantly to the unplanned outages that occurred in the medium voltage (MV) distribution grid. Blown fuse and loose contact faults were the major contributor to unplanned outages in the low voltage (LV) electric power distribution grid.
Experimental Study of Beeswax / Rice Husk Ash Phase Changes Material as Energy Storage in Concrete
Authors: Thaib Razali
Published: February 2022

Buildings with lightweight concrete are currently used as a solution for mass housing construction which is relatively cheaper, although it does not provide indoor thermal comfort due to the use of this building material. Lightweight concrete building materials are able to store heat for a long time, so that at night the heat is released indoors. The combination of building materials and PCM is an efficient way to increase the storage capacity of thermal energy in building components. The purpose of this study was to determine the compressive strength of the concrete if the coarse aggregate (gravel) was replaced by part of the gravel material using the Phase Change Material of beeswax (beeswax) according to the required percentage starting from 0%, 5%, 10%, 15% and if the aggregate was fine. (Sand) is partially replaced aby using Rice husk ash with various variations starting from 0%, 5%, 10%, 15%. In addition, this utilization is a good alternative, because there will be a process of utilizing rice husk ash which was previously wasted while these items can be used or processed into additives to the concrete mixture.
Naboth’s Vineyard: A guide for South Africa on the Vexing Land Issue
Authors: Shamase Maxwell Zakhele , Nicolaides Angelo
Published: February 2022

The story of Naboth’s vineyard (1 Kings 21:1-16) is one played out during the dynasty of Omri in Northern Israel (866-842 BCE) and speaks to an era in which socio-economics were largely dominated by political elites. The narrative concerns inter alia a clash between two arrangements of land ownership, inheritance and possession by others. Thus, from a socio – analytical perspective, the story has lessons to impart to 2022 South Africa where the issue of the land redistribution is an important one given that even after a quarter of a century post-apartheid, millions of people continue to have no real access to land. Many people are thus left precariously exposed and vulnerable. The story imparts the truth that a leader of a state is bound to respect the proprietary rights of his citizens. In any event, viewed from a theological perspective, all the resources of creation are to be utilised to serve the common good and we are all custodians of creation. This includes people who have no private property of their own and who are for the most part excluded and side-lined by those in positions of power. The story of Naboth’s vineyard is thus a simple one where a sovereign sees something he wants, and then formulates a strategy to get it. In Naboth’s story, the king had him killed. This is a very constructive rendition of what happens when there’s no justice and the dominant powers get to terminate those who stand in their way. Justice tends to break down when people lose perspective of who they are concerning God who ultimately forgives us when we atone.
Human’s Plexus Systems and “Nikola Tesla’s 369 Theory” for Forming Universe and God
Authors: Shrestha Mahesh Man
Published: February 2022

All activities which are taking place in the Cosmos also exist in a human body in subtle micro-scale. Plexuses centers in a human body are the most mysterious kinds of energies. The six-center plexus system is the path of the Kundalini shakti, the primordial cosmic energy of a person. Each plexus has its own propensities (vibrating words/dimensions/vritti) and an acoustic root. These plexuses control some cluster of words of sounds and corresponding physical organs in human body. The 50 main propensities of the human’s unit mind are expressed through the vibration-expression of these plexuses. These vibrations cause hormones to secrete from the corresponding glands of the human’s body. These plexuses can play very important roles in curing the diseases. According to the Theory of Nikola Tesla’s 369, there are all together 1 to 9 digital root numbers exist. All other higher or lower numbers are the combination of those digital root numbers. This statement seems quite true when we compare it with Theory of Absolutivity. If 3, 6, 9 numbers are arranged together it makes a letter Ohm (AUM) which represents actually a Sagun Bramh/Nikola Tesla’s 369 triangle which is a part of NirgunBramh having  higher dimensions. Number zero is the NirgunBramh (having all the qualities but in dormant form) which does not possess any quality in action. Number 3, 6, 9 forming as an equilateral triangle of static, mutative and sentient forces representing the Black-hole which is a part of Sagun Bramh projecting Himself as a Visible World through Big-bang along with forming five basic elements such as Ethereal, Areal, Fire, Liquid and Solid. According to the biological science, life emerged in this planet from matter about four billion years ago in the form of DNA that carried the software for the development of billion of species on the way to its final destination in humans. These facts also fully support the above hypothesis of universe formations.

Published: February 2022

Microsatellite instability (MSI) characterizes a special molecular genetic subtype of malignancies and is associated with the deficiency of mismatched DNA repair. There are no reliable data on the frequency of MSI in colorectal neuroendocrine neoplasms due to the relative rarity of this cancer type. The prognostic significance of MSI is debatable. The aim of this study was to investigate the frequency of the MSI phenotype among colorectal neuroendocrine neoplasms (NENs) with different primary location, grade and stage. Twenty-nine patients (15 men and 14 women, mean age: 62.5 years) included in the study underwent surgery for colorectal neuroendocrine tumors between 2015 and 2018. The mean follow-up period was 3.8 years. Colorectal NENs were grouped by primary location and stage. The majority of the patients (52%) had stage III cancer at diagnosis. The microsatellite stability (MSS) phenotype was confirmed in 24 patients (83%), whereas the MSI phenotype was observed in 5 patients (17%). All MSI-positive tumors were stage I well-differentiated grade G1 or G2 neuroendocrine tumors (NETs) of the rectum. Overall survival was 50% for patients with stage II MSS-positive NENs of the colon and rectum, 33% for stage III and 0% for stage IV. For patients with stage I MSI-positive NENs of the rectum, overall survival was 100%. Thus, the frequency of MSI-positive colorectal NENs was estimated.

Introduction

La surveillance des inégalités en santé vient en soutien aux politiques destinées à réduire ces inégalités tôt dans la vie. Notre étude visait à examiner l’évolution des inégalités dans six domaines de la santé en fonction du genre et du statut socioéconomique.

Méthodologie

Les données proviennent de cinq cycles quadriennaux de l’Enquête sur les comportements de santé des jeunes d’âge scolaire (Enquête HBSC) menée au Canada (échantillon groupé : 94 887 participants). Les différences sur le plan de la santé en fonction du statut socioéconomique (d’après la défavorisation matérielle) et du genre ont été évaluées à l’aide d’indices relatifs et de pente d’inégalité dans six domaines de la santé : activité physique quotidienne, surplus de poids, symptômes physiques fréquents, symptômes psychologiques fréquents, faible satisfaction à l’égard de la vie et état de santé auto‑évalué comme passable ou médiocre.

Résultats

En 16 ans, l’état de santé déclaré par les adolescents du Canada s’est graduellement détérioré dans quatre domaines de la santé, les déclins les plus marqués ayant été constatés dans le groupe socioéconomique le plus défavorisé. Les différences selon le statut socioéconomique se sont accentuées sur le plan du surplus de poids, des symptômes physiques, de la faible satisfaction à l’égard de la vie et d’un état de santé passable ou médiocre. Les différences selon le genre se sont aussi approfondies. L’état de santé des filles était moins bon que celui des garçons dans tous les domaines sauf celui du surplus de poids, et les différences selon le genre ont augmenté au fil du temps sur le plan des symptômes physiques, des symptômes psychologiques et de la faible satisfaction à l’égard de la vie.

Conclusion

Les inégalités liées au genre et au statut socioéconomique sont persistantes et elles se creusent chez les adolescents au Canada. Mettre en place des mesures est nécessaire pour s’attaquer aux facteurs matériels et sociaux qui contribuent aux inégalités en santé durant l’adolescence.

Published: February 2022

This research was aimed at describing the extent to which strategy does the teachers use in teaching descriptive writing to students at Junior High School and finds out the reasons underlying the teachers using certain theory. The strategy which the teachers use was analyzed by following the theory of Johns’ Scaffolding Strategy (2010). Scaffolding Strategy divided into Explicit Implementation consist of three types namely (1) modeling; (2) joint negotiation and (3) independent construction. And the other one is Implicit Implementation which consists of four types namely (1) dimly felt of sense; (2) begin composing; (3) course composing and (4) external feedback. The data was analyzed following Miles and Huberman theory of qualitative research (1994). The research findings showed that, the English teachers are using all three types of explicit implementation and only one type of implicit implementations, namely external feedback. And the reasons underlying teachers using these implementations are (1) the teachers want to vivid students’ knowledge about the generic structure, language features and social functions of descriptive text, (2) teachers want the students to understand more and get familiar with descriptive text in real life, (3) teachers wants to know students’ ability in applying their knowledge of descriptive text on their own-making descriptive text and (4) enlighten students on how to criticize their friends’ work.Keywords: Descriptive, scaffolding, explicit implementation, implicit implementation

Published: February 2022

Abstract: As a result of the COVID-19 pandemic, the education sector in Malaysia had undergone drastic changes and new norms are now in place. Among them are online home teaching and learning (PdPR) activities. This situation has become challenging and worrying especially in the primary school education sector. The Ministry of Education (2021) reported that there were 2,741,837 pupils in primary schools, compared to 2,037,433 pupils in secondary schools. These large numbers certainly affect the way school leaders manage the available resources. To alleviate this problem, school leaders are seen to have played an important role in helping teachers and pupils to adapt to the new online home teaching and learning (PdPR) environment. Therefore, this study examines the distributive leadership practices on the efficiency of primary school teachers during the COVID-19 pandemic period and challenges from the perspective of school leaders in managing and leading schools during this difficult period. A qualitative design with a phenomenology approach was used in studying and exploring their experiences. Five informants had collaborated in this study, and five main themes emerged: designation and sharing of school missions, visions, and goals; sharing of responsibilities; giving positive changes to teachers and students; giving changes to teachers to develop leadership skills; and cooperation -  coordination and mutual understanding between education leaders and teachers. Through these themes, it is found that distributive leadership can be consistently pre-dedicated across all educational institutions. Besides sharing responsibilities, distributive leadership had enhanced teachers' knowledge and skills.

Onlyfans, el sexo en la época de su reproductibilidad técnica
Authors: González Ramírez Yulfren Jhonattan
Published: February 2022

El desnudo y el sexo han sido categorías históricamente reprimidas debido a la creencia de que el cuerpo es una obra de Dios y su pureza nos acerca a él. Onlyfans es una app que da acceso a contenido sin censura. Desde la segunda mitad del siglo XX, el paradigma sobre la sexualidad heredado del cristianismo, ha sido progresivamente superado. Lo que antes era visto como algo único (incluso, sacro) mediante la reproductibilidad técnica ha sido masificado y convertido en ordinario. Si la desnudez y el sexo, en la antigüedad, estaban ligados a actos religiosos relativos a la fecundidad, y luego la iglesia los retrotrajo a la intimidad del lecho matrimonial heterosexual, hoy los medios técnicos han «desocultado» el sexo. Aquí se plantea cómo aplicaciones como Onlyfans destruyen el aura de la desnudez y del sexo.

One form of intervention that can be done to individual smokers can be done by applying hypnotherapy methods. Hypnotherapy methods are commonly used in social work practices especially in the arena of clinical social work or medical social work. This method is in line with the strength perspective and connection between mind and body approach. This paper aims to describe the process of hypnotherapy to individuals with smoking habits.This study operates descriptive qualitative method with three informants, that is two clients who accept therapy and a hypnotherapist. Interviews and observation use as data collection techniques. The results showed that the hypnotherapy method for clients with smoking habits was divided into seven stages, namely pre-induction, induction, deepening, depth level test, suggestion therapy, hypnotherapeutic technique and termination. However, because there are differences in each client's goals, namely reducing and stopping, the suggestion therapy and hypnotherapeutic technique sections are adjusted to these goals. The difference lies in the technique of manipulation and substitution. However, there are similarities in the purpose of the technique given to both, which is to eliminate comfort in smoking activities.
