Authors: ABIODUN Kayode , OGUNWUYI Babatunde , ADEJIMOLA Iwalewa
Published: January 2021

Positive attitude of students towards counselling is necessary in any level of education. Many studies had investigated self-esteem, social-economic status, emotional intelligence on attitude towards counselling of students in secondary schools but not in theological colleges. This study however investigated parental and peer factors as determinants of attitude towards counselling of students in CAC Theological Seminary, Akure. All students were used for the study. Reliable instruments were used to collect information from the respondents. Parental Factors Scale (r = 0.75), Peer Influence Scale (r = 0.74) and Attitude Towards Counselling Scale (r = 0.85) were used for data collection. Pearson product moment and multiple regression analysis were used for data analysis. The result shows that peer influence was related to (r = .365) while parental influence (r = .122) did not relate to attitude toward counselling of students in CAC Theological seminary. The independent variables jointly contributed to students’ attitude towards counselling (Adjusted R2 = 1.09, F2 = 5.261) and accounted to 13.4% contribution to attitude towards counselling. The parental influence (= -.025) did not contribute to students’ attitude towards counselling while peer influence (= 3.75) contributed to students’ attitude toward counsellings. It is recommended that parents of student should be more helpful in motivating the students to seek counselling and parents should train their children on how to associate themselves to friends who could help them to seek counsel in appropriate place for good performance in life and ministry.
COMPETITIVE PARITY AND MARKETING PERFORMANCE OF NIGERIA BREWERIES PLC.
Authors: Maximus Nwaohiri , Onuoha Chima
Published: January 2021

Nigeria, just like most alcohol drinking countries around the world, is in the middle of a brutal beer war that has seen competing beer makers suffer declining bottom lines in exchange for higher market share. In Nigeria, this battle is currently between three major brewers: International Breweries, Guinness Nigeria and Nigeria Breweries. Keen competition among producers in the breweries industry had led to the search for production strategy and cost management technique to survive and outwit competitors. These goals, strategies and techniques are known as competitive parity. In the light of this, the study evaluates the competitive parity and marketing performance of Nigeria Breweries Plc in Nigeria amidst the stiff competition from other formidable beer brands. The paper derives its justification from the stiff rivalry that has characterized the high promotion war amongst firms in the industry, and the attendant tendency of adversaries. The competition amongst firms in an industry is identified as bearing on a contest to gain brand superiority, thereby shifting emphasis to place and promotion utilities of the marketing mix. The study relied on extant literature survey to identify strategic and tactical imperatives for survival of firms in the industry. It contended that defensive strategies and PEST analysis are sine quo non for competitive intelligence to sustain realistic and impactful existence in the highly competitiveness in the world of breweries in Nigeria.

The purpose of this study was to examine the effect of strategic pricing/pricing strategies on the marketing financial performance of Beverage firms in South-southern Nigeria. The area of study is Rivers state, while five firms were selected based on convenience. A sample size of 201 respondents was employed. The study employed dimensions of pricing strategy such as; Price skimming, Penetration pricing and Price discrimination and measures such as customer satisfaction. The correlational analysis was employed and indicated that there was a statistically significant and positive relationship between pricing strategies and marketing performance. These results implied that economy pricing has a positive effect on the marketing performance of beverage companies. The study recommends that; Beverage firms should put in place measures to reduce product costs and thus increase marketing performance whenever such a strategy is used. Also, these firms should also adopt ways to implement their pricing strategies better compared to competitor firms. They should undertake market survey when formulating prices for their services. They should identify the prices charged by their competitors in order to come up with prices which are nether too low or very high.

COVID-19-related health behaviour changes among Ghanaians: applying the health belief model
Authors: Amankwah-Poku Margaret
Published: January 2021

Although the Coronavirus disease2019 (COVID-19)is a physical illness, it very much requires behavioural practices to prevent its infection and transmission. Coronavirus protective measures may sound simple to adhere to compared to chronic disease-related behavioural practices, but this is not the case. Understanding adherence to COVID-19-related health behaviours using the health belief model as an explanatory model, can help to design interventions for change and maintenance of this change. The health belief model posits that, practicing a health behaviour depends on the individual’s perceived susceptibility to a disease, his/her perceived severity of the disease, and the perceived benefits/cost of engaging in the health behaviour, all of which are prompted by internal and external cues to action. Some Ghanaians may believe they are not susceptible to the disease or may downplay the severity of the disease, and thus will be less likely to engage in the health behaviours to avoid COVID-19 infection. Again, if Ghanaians believe the cost of engaging in these behaviours outweigh the health benefits of adhering to the behaviours, then they are less likely to follow these health behaviours. Finally, internal (e.g. experiencing COVID-19 symptoms) and external (e.g. daily COVID-19 updates) cues may act as triggers to engaging in health behaviours. Ghanaians should be well educated about the coronavirus and well informed, to be equipped to adhere to the COVID-19 protective measures. Clinical and health psychologists should be engaged to champion behaviour change practices.
Transfemoral embolization of a large symptomatic renal angiomyolipoma in a horseshoe kidney: a case report and literature review
Authors: Sarkodie Benjamin D , Anim Dorothea A , Jimah Bashiru B
Published: January 2021

Renal angiomyolipomas (AML) are the commonest benign renal neoplasms. They are composed of blood vessels, adipose tissue, and smooth muscle in varying amounts. It is quite rare to find AML in a horseshoe kidney, although there is at least one such reported case discovered in pregnancy and managed by resection. Spontaneous hemorrhage which could be fatal is the most feared sequelae of AML. The first-line of management for AMLs was previously surgical excision. However, advances in minimally invasive techniques that have a lower risk of complications have broadened treatment options for reducing tumour size and preventing hemorrhage. One of such effective techniques is selective arterial embolization (SAE) of renal AMLs > 4cm. Patients not requiring any immediate intervention maybe followed up with active surveillance. In this case report, we present a case of AML in a horseshoe kidney that was successfully treated with transfemoral embolization as well as a review of the literature.

Therefore, an increase in the use of activities related to AR applications in education processes is predicted to be beneficial for teaching and learning
Temperature Inversion and Ultrafine Particulate/Near Ultrafine Particulate Matter Concentrations in the Salt Lake Valley
Authors: Mecate Danielle , Handy Rod , Pahler Leon , Sleeth Darrah , Ramsay Joemy , Schaefer Camie
Published: January 2021

Ultrafine particulate (UFP) matter exposures are associated with negative health outcomes. UFPs (<100nm) and near UFP (NUFP) matter (4.5nm - 250nm) are trapped by the bowl-like geography of the Salt Lake Valley causing winter inversions (i.e., trapped particulate matter (PM)). Enmont PUFP C100 and Grimm 1.109 particle counters were used to define NUFP concentrations during inversion (n=5) and non-inversion (n=5) days at 7 sites. NUFP concentrations served as a proxy for the UFP fraction. NUFP concentrations were log-transformed and multivariable mixed effects linear regression models determined if NUFP concentration differed between inversion and non-inversion or by length of inversion. Difference in fraction NUFP was also analyzed. The mean NUFP concentration was 1.49-fold higher during inversions (95% CI 1.11–2.02), whereas the fraction declined by 0.22 (95% CI -0.31– -0.13). Increased NUFP concentrations during inversions may lead to increased adverse health outcomes. These findings have serious implications for inversion-prone regions.

Published: January 2021

This article discusses the Economic Reflections of Asean countries in facing the Covid-19 Pandemic in several Asean countries, namely Vietnam, Malaysia and Indonesia. Vietnam's economic growth was victorious, the economies of various countries in other Southeast Asian regions were battered by the corona virus. The process of economic growth is influenced by two kinds of factors, namely economic factors and non-economic factors. Economic factors, which are none other than production factors, are the main force affecting economic growth. Malaysia has proven to the world community that its country is capable of managing its economy even in challenging circumstances. He quoted the IMF as global economy recorded negative growth and in Indonesia it seems that contraction in income activities in some income classes is affected. In the second quarter there is a slowdown, then in the third quarter the savings are enormous. It could be that consumption, which has been a factor in economic growth, will be a challenge. In an effort to maintain economic stability during the Covid-19 pandemic. This reflects that the economies of ASEAN countries, even in the world, are currently under the same pressure due to the Covid-19 virus pandemic, the world economy this year will experience a recession.

The Starving Sex: Psychoanalysis of Gendered Identity Crisis in the Gothic Novel
Authors: Al-Hilo Mujtaba , Gebreen Hayder
Published: January 2021

This paper investigates the socio-historical context in which the Gothic novel appeared. It seeks to shed light on the psychological side of this debut. One of the problems of recent studies in this regard is that they tend to detach the appearance of the Gothic novel from the historical context that gave birth to this genre. This leads to inaccurate findings and conclusions because this genre rose out of necessity. It was a method of fighting back the suppressive social conditions from which females suffered. This study is necessary to reveal the oppressive context females endured, and how that patriarchal ideology was universally and rationally justified and eluded any possible questioning. This suppressive condition was deeply rooted in the unconscious of subjects. Gothic novel was a revolution against that prevailing ideology, socially, religiously, and intellectually. It was considered a form of atheism. In this regard, this paper seeks to question the validity of the appearance of this genre and the way it is justified. It also presents a host of findings that displays the necessity out of which this genre rose, with references to Emily Bronte’s Wuthering Heights and Mathew Lewis’ The Monk.

Fish Habitat: Essential Fish Habitat and Rehabilitation
Authors:   The Academy of Natural Sciences, Estuarine Research Center 10545 Mackall Road, St. Leonard, Maryland 20685, USA
Published: January 2021

Abstract .—The importance of molluscan-dominated systems (e.g., oysters reefs, mussel beds, vermetid gastropods) to the maintenance of commercially and ecologically important species has not been as broadly recognized as has been the importance of other structurally complex estuarine habitats such as sea grass beds and salt marshes. As a consequence, these systems have often been unappreciated and understudied. Important ecosystem services of molluscan-dominated systems include: (1) filtering capacity; (2) benthic– pelagic coupling; (3) creation of refugia from predation; (4) creation of feeding habitat for juvenile and adult mobile species as well as sessile stages of species that attach directly to molluscan shells; and (5) provision of nesting habitat. Destructive harvesting and overfishing can reduce habitat extent and impair habitat functioning. Only recently have ecosystem services been incorporated into the management of these systems. The role of oyster reefs as “essential fish habitat” falls into two principal categories: (1) reefs as habitat for oysters and (2) reefs as habitat for resident and transient species. Although the former role has received some attention as part of efforts to restore oyster resources, the latter role remains largely unexplored. The role of oyster reefs as critical habitat for other species is suggested by the diverse fauna associated with them; however, the factors that control the development of these reef-associated assemblages are generally unknown, and enumeration of specific habitat services using replicated field experiments is just beginning. Using data summarized from studies in Maryland, Virginia, North Carolina, South Carolina, and Texas, we classify finfish assemblages associated with reefs based upon the degree of their association and include an extensive finfish and decapod species list. We conclude, within the context of the current state of knowledge, that (1) the construction of reef bases using materials that provide adequate vertical relief and interstitial space and (2) the establishment of broodstock sanctuaries protected from harvesting pressure are important for restoring oyster populations. Utilization of reef habitats by numerous commercially, recreationally, and ecologically important species across a wide geographic range likely portends the reef habitats’ importance as essential fish habitat, but many functional relationships remain to be evaluated. Future oyster habitat research needs include (1) defining the morphological and spatial reef characteristics that support enhanced oyster growth and survival; (2) improving understanding of how harvest methods affect reef integrity and function; (3) determining the critical services provided by reef habitats in the life cycles of important species; and (4) further clarifying the trophic links between the resident fauna on oyster reefs and transient species.

Published: January 2021

In the present scenario of globalization and liberalization, it is imperative that Indian industries become fully conscious of the needs to produce reliable products meeting International standards. Reliability of a system can be maximized by attaching parallel components to each of the components in the system such that if one component fails, one of its parallel components comes into operation and the system does not fail until all parallel units fail. Integrated Reliability Model refers to the determination of the number of components, component Reliabilities, stage Reliabilities and the system Reliability wherein the problem considers both the unknowns that is the component Reliabilities and the number of components in each stage for the given cost constraint to maximize the System Reliability. In this work an attempt is made to develop an integrated reliability model for a series-parallel configuration subject to the cost, weight and volume constraints .The Lagrangian Multiplier method is used to determine the component reliabilities, stage reliabilities, number of components in each stage and the system reliability for a series-parallel configuration. Using this method, rounded values cannot be obtained, but number of components should be an integer. To get the integer value, Integer programming has been successfully used.
VIBRATION STUDY OF MAGNETORHEOLOGICAL FLUID FILLED SANDWICH BEAMS
Authors: JOSHI SHRIKANT B.
Published: January 2021

The concept of vibration mitigation in flexible structures using smart fluids has attracted researcher’s interest in the last few years. Significant research work has been done on the structures with electrorheological fluids, but there has been a little work with the magnetorheological fluids. This study investigates the vibration controllability of MR fluid filled cantilever beams under externally applied magnetic fields. The adaptive structures were fabricated by adding a MR fluid layer between the adjacent elastic layers and the properties of two different types of sandwich beams were studied. In the first type, free and forced vibration responses of aluminium beam with partial treatment were evaluated and compared with fully filled beam. The controllability of vibration response was observed in terms of variations in vibration amplitudes and shifts in magnitudes of the resonant natural frequency. In second type, a composite cylindrical sandwich cantilever beam with end plate was fabricated. It consisted of outer stainless steel hollow pipe with end mass, inner wooden rod and an embedded MR fluid. Inner rods with different diameters were used to vary the thickness of MR fluid layer. Forced vibration response of such beams exhibited increased damping under increased magnetic fields.

Published: January 2021

A failure analysis based on stress life approach may be useful for predicting the life time of weld in the structure. This study presents an upcoming methodology in new three dimensional Finite Element Model to calculate the fatigue life of weld. Ansys 12.1 simulation software uses stress-life method, based on a static non-linear Structural analysis. The weld material S-N curve were experimentally determined by the Fatigue testing of the dumbell specimen as per 7608 standard. This study assumes that a flaw exist in weld due to welding process, material in-homogeneity, air voids, slugs or impurities in weld, improper surface machining and many more. This material curve is used in simulation to get more accurate results. Thus the fatigue life prediction with the material curves from experimentation will give us more accurate and close to actual failure results.

In recent years, much research has been carried to find suitable alternative fuel to petroleum products. In the present investigation experimental work has been carried out to analyze the performance and emissions characteristics of a single cylinder compression ignition DI engine fuelled with the blends of mineral diesel and biodiesel at the different injection pressures. The optimal value of the injection pressure was observed as 200 bar in the range of 180 to 220 bar. The performance parameters evaluated were brake thermal efficiency, break specific fuel consumption and the emissions measured were carbon monoxide (CO), carbon dioxide (CO2), hydrocarbon (HC), and oxides of nitrogen (NOx). The results of experimental investigation with biodiesel blends with diesel are compared with that of diesel. The results indicated that the CO emissions are slightly less, HC emissions were also observed to be less for B10 and B20, and NOx emissions decreased by 39 % for B10 and 28 % for B20 compared with B100. The brake thermal efficiency of the engine decreased around 6% for all blends in comparison with diesel, and the break specific fuel consumption was slightly more for B10 and B20.

Published: January 2021

Conventional monolithic materials have limitations in achieving good combination of strength, stiffness, toughness and density. To overcome these shortcomings and to meet the ever increasing demand of modern day technology, composites are most promising materials of recent interest. Metal matrix composites (mmcs) possess significantly improved properties including high specific strength, specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. Among the mmc’s aluminum composites are predominant in use due to their low weight and high strength. The key features of mmc’s are specific strength and stiffness, excellent wear resistance, high electrical and thermal conductivity. The present investigation aims at the development of aluminium based e-glass and flyash particulate reinforced hybrid metal matrix composites. The test specimens are prepared as per astm standard size by turning and facing operations to conduct tensile and compression test.

The fixture design and analysis lead-time is always a major influencing factor for the bottleneck between product design and manufacturing. With advent analysis and simulation tools, there is a lot of potential to expand the scope of optimization of fixture elements to achieve the objectives such as ‘maximizing rigidity’ and ‘minimizing weight’ of a fixture assembly. There are many sources which affect the rigidity of fixture assembly. The rigidity of fixture assembly mainly depends upon various factors such as material properties, geometry of individual components, stability against thermal distortions, clearances or plays on fixture elements (to facilitate loading and unloading of workpiece), contact deformations at contacting surfaces, etc. Among these, contact deformations at contact interface are one of the important sources of errors in precision fixture design. These contact deformations are measure of contact stiffness and therefore needed to be studied in accordance with workpiece-fixture contact. In this paper, a numerical model of fixture unit assembly is presented using the FEA tool ANSYS. ANSYS contact elements CONTA175 (8 node element) and TARGE170 (8 node quadrilateral element) are utilized to represent contact stiffness at contact interface. This model simulates the behavior of contacting surfaces of fixture assembly for different values of surface roughness, coefficient of friction (μ) and contact stiffness with very little modelling or computational efforts and time. This work establishes the FEA model of fixture unit assembly to predict fixture unit stiffness and FEA model of rough surface contact to predict contact stiffness. Based on this study, the database of fixture stiffness and contact stiffness is built up and further can be used in computer aided fixture design (CAFixD).

Images make up a major component of multimedia content. Digital arts, illustrative diagrams, cultural heritage paintings in digitized for and digital photographs are examples of images. Advances in computing hardware, software, and computer networks have created threats to copyright protection and content integrity. In this paper, a new method for lossless visible watermarking is proposed by using appropriate compound mappings that allow mapped values to be controllable. The mappings are proved to be reversible for lossless recovery of the original image. The approach is generic, leading to the possibility of embedding different types of visible watermarks into cover images. Two applications of the proposed method are demonstrated, where opaque monochrome watermarks and non uniformly translucent full-color ones are respectively embedded into color images.

This Thesis presents a design of the Folded-cascade operational amplifier which leads to high gain as compared to a normal cascade circuit. In this project; specifications of analog systems into op amp level net-lists of library components is studied and simulated using XILINX. As the power-supply voltages because of the technology improvement and it are desired to reduce power supply to minimize power dissipation, many challenges are faced by the analog designer. One is to keep noise level as possible. The op-amp must be designed to with the ever decreasing power supply voltages. As the power supply voltages begin to approach 2Vt, new technique and new op-amp topology like folded cascade should be used.
SPEED CONTROL OF INDUCTION MOTOR USING ADR CONTROLLER

Published: January 2021

The control of induction motors has been a primary concern of researchers. Proportional-integral- derivative (PID) control and direct torque control (DTC) have been proposed for induction motors [1-6]. However, the control of induction motors is still a challenging problem due to the following issues: 1) the dynamic system of an induction motor is highly nonlinear; 2) the rotor resistance varies because of heating. In this paper, a reduced-order active disturbance rejection control (ADRC) with reduced order extended state observer (RESO) is applied for induction motor control. The ADRC is employed for controlling a slip.
3D TARGET DETECTION USING STACKED HOLOGRAM

A very popular technique of 3D vision now-a-days is holography which has many advantages over the stereoscopic 3D vision. The same technique can be implemented on RADAR to take high resolution 3D picture of the target and to track with very minute displacement. As this does not employ parallax method, so binocular antenna can be replaced by a single antenna. Again in this thesis another new concept, gated range, is implemented, i.e., the target can be detected within a certain range on spatial domain so that it can focus to the target and the clutter has no effect on it. Narrow virtual transmit pulses are synthesized by differencing long-duration, staggered pulse repetition interval (PRI) transmit pulses. PRI is staggered at an intermediate frequency IF. Echoes from virtual pulses form IF-modulated interference patterns with a reference wave. Samples of interference patterns are IF-filtered to produce high spatial resolution holographic data. PRI stagger can be very small, e.g., 1-ns, to produce a 1-ns virtual pulse from very long, staggered transmit pulses. Occupied Bandwidth (OBW) can be less than 10 MHz due to long RF pulses needed for holography, while spatial resolution can be very high, corresponding to ul tra-wideband (UWB) operation, due to short virtual pulses. X-Y antenna scanning can produce range-gated surface holograms from quadrature data. Multiple range gates can produce stacked-in-range holograms. Motion and vibration can be detected by changes in interference patterns within a range-gated zone.

Published: January 2021

The Fetal Electrocardiogram (FECG) signal reflects the electrical activity of the fetal heart. It contains information about the health status of the Fetus and therefore, an early diagnosis of any cardiac defects before delivery increases the effectiveness of the appropriate treatment. This paper proposes the use of Adaptive Neuro Fuzzy Inference Systems (ANFIS) for Fetal Electrocardiogram (FECG) extraction from two ECG signals recorded at the Thoracic and Abdominal areas of the mother’s skin. Wavelet transform is performed on ANFIS output to extract pure FECG with high Signal to Noise Ratio (SNR) and low error rate. The effectiveness of this technique is underlined in this paper.

Çeşitli Bitki Taksonlarında Bazı DNA İzolasyon Yöntemlerinin Karşılaştırmalı Analizi
Authors: YILMAZ SANCAR Pelin
Published: January 2021

Bitkilerde moleküler düzeyde yapılan çalışmalar, incelenen taksonlardan maksimum kalitede DNA eldesi gerektirmektedir. Bu nedenle, çalışılacak bitkilerden yüksek konsantrasyonlu ve mümkün olabildiğince saf DNA eldesi son derece önemlidir. Bitkilerden genomik DNA izolasyonu için farklı protokoller bulunmaktadır. Bu araştırmada tıbbi ve aromatik bitkilerden Asteraceae, Apiaceae ve Lamiaceae familyalarına ait bazı taksonlar kullanılmıştır. Taksonların hem herbaryum materyali haline getirilmiş kuru yaprak dokularından, hemde taze yaprak dokularından örnekler alınarak denenecek yöntemlerin hangi tip dokularda daha etkin olduğu araştırılmaya çalışılmıştır. Kullanılan yöntemlerde ekstraksiyon tampon çözeltileri içinde yalnızca CTAB ile CTAB+PVP beraber olacak şekilde hazırlanmış, buna ilave olarak hazır izolasyon kiti kullanılmıştır. Genel olarak tüm yöntemlerden yüksek konsantrasyonda DNA elde edilirken, bu yöntemlerle elde edilen gDNA’da, proteinler, RNA, polisakkaritler, uçucu yağlar, fenoller ve diğer kirleticilerin miktarı minimal düzeye indirilmeye çalışılmıştır. İzole edilen DNA’ların konsantrasyonu ve saflığı nanodrop spektrofotometrede ölçülürken, yoğunluğu agaroz jel elektroforezinde görüntülenmiştir. Ayrıca elde edilen DNA’ların PCR çalışmalarına uygunluğu da çeşitli primerler kullanılarak test edilmiştir. Elde edilen DNA’ların miktarı ve kalitesi taksonlar arasında farklılık gösterse de en kaliteli izolasyon her zaman taze bitki materyali kullanılarak yapılan izolasyonlardan elde edilmiştir. Bununla birlikte yalnızca CTAB çözeltisi kullanılan ekstraksiyon yöntemi en yüksek saflık ve yoğunlukta olan DNA’ yı sağlamıştır. Bunu takiben CTAB+PVP yöntemlerinin benzer sonuçlar verdiği görülürken, hazır kit kullanımının ise bitkilerden DNA izolasyonunda çok da kullanışlı olmadığı saptanmıştır. Hazır kit kullanımı her ne kadar daha temiz görünümlü DNA verse de elde edilen DNA’ların yetersiz olduğu görülmüş ve PCR çalışmalarında müspet sonuç vermemiştir.
