Published: February 2021

This is a case report of a 55-year-old man with Type 2 Diabetes Mellitus who presented with progressive breathlessness, chest pain and hyperglycaemia. An initial impression of a chest infection was made. Management was initiated with antibiotics, but this was unsuccessful, and he continued to desaturate. A screen for Coronavirus Disease of 2019 (COVID-19) returned positive. There was no prodrome of fever or flu-like illness or known contact with a patient known to have COVID-19. This case is instructive as he didn’t fit the typical case definition for suspected COVID-19. There is significant community spread in Ghana, therefore COVID-19 should be a differential diagnosis in patients who present with hyperglycaemia and respiratory symptoms in the absence of a febrile illness. Primary care doctors must have a high index of suspicion in cases of significant hyperglycaemia and inability to maintain oxygen saturation.Patients known to have diabetes and those not known to have diabetes may develop hyperglycaemia subsequent to COVID-19. A high index of suspicion is crucial for early identification, notification for testing, isolation, treatment, contact tracing and possible referral or coordination of care with other specialists. Early identification will protect healthcare workers and patients alike from cross-infection.

Gastrointestinal tract (GIT) in human plays an important role in providing habitat to various microbial communities including numerous prokaryotic cells numbering over 100 trillion. This study was aimed at accessing the multidrug resistance (MDR) of E. coli among patients with GIT infections seeking health care at Dalhatu Araf Specialist Hospital (DASH), Lafia, Nasarawa state, Nigeria. A total of one hundred and fifty (150) stool samples were collected using sterile sample containers from patients with symptoms of GIT infections in search of medical care in this hospital. The samples collected were processed using standard microbiological methods. Out of the total samples collected, 35.3% (53/150) revealed the presence of E. coli whereas 64.7% did not. Extended spectrum beta-lactamases (ESBL) were found in 45.3% of E. coli obtained in this study, which were further used for the antimicrobial susceptibility test. E. coli were more resistant to ampicillin (75.51%), followed by amoxycillin/clavulanic acid (61.22%) and were least resistant to imipenems (12.25%). In conclusion, MDR E. coli producing ESBL are abundant among patients with GIT infections visiting DASH, Lafia. Thus, it is important to determine the genes responsible for this MDR as well as dissemination of adequate information to the masses visiting the hospital for treatment on the possible effects caused by the antibiotics abuse

Authors: Adesina S.A. , Ajibare A.O. , Ebimowei O.G.
Published: February 2021

A fifty-six (56) day experiment was conducted to evaluate the growth performance and feed utilization in Clarias gariepinus fingerlings fed with six iso-nitrogenous diets in which oven-dried melon (Citrillus lanatus) seed peel meal (MSPM) was substituted for yellow maize at 0, 20, 40, 60, 80 and 100% inclusion levels. A total of 270 fingerlings of C. gariepinus (mean weight: 7.40 ± 0.02 g) were randomly allocated into eighteen plastic bowls (50-litre capacity) at 15 fish per bowl and fed the control and experimental diets twice daily at 5% of their body weight. Proximate composition of melon seed peel meal-supplemented diets and fish carcass was determined using standard procedures. Results showed that crude protein was highest (60.75%) in fish fed diet 2 (20% MSPMsupplemented diet) and least (58.21%) in fish fed diet 4 (60% MSPM-supplemented diet). Fish fed diet 2 (20%MSPM-supplemented diet) had statistically (p < 0.05) superior values of MWG (48.27 g), SGR (1.56%/day) and FCR (0.48) beyond which growth and feed utilization indices gradually declined with increased level of MSPM inclusion. This study demonstrated that 20% substitution level of oven-dried melon seed peel meal produced the best growth and feed utilization in C. gariepinus.

Markowitz Model Investment Portfolio Optimization: a Review Theory
Authors: Abdul Hali Nurfadhlina , Yuliati Ari
Published: February 2021

In the face of investment risk, investors generally diversify and form an investment portfolio consisting of several assets. The problem is the fiery proportion of funds that must be allocated to each asset in the formation of investment portfolios. This paper aims to study the optimization of the Markowitz investment portfolio. In this study, the Markowitz model discussed is that which considers risk tolerance. Optimization is done by using the Lagrangean Multiplier method. From the study, an equation is obtained to determine the proportion (weight) of fund allocation for each asset in the formation of investment portfolios. So by using these equations, the determination of investment portfolio weights can be determined by capital.

The Administration of Heritage Language Programs: Challenges and Opportunities
Authors: Benmamoun Elabbas , Kagan Olga
Published: February 2021

This paper grew out of a presentation given by Elabbas Benmamoun at the Sixth Heritage Language Research Institute held at UCLA in June, 2012. On the last day of the institute, Benmamoun participated in a panel entitled Lessons Learned: The Implications for Flagship Programs. The Language Flagship, which co-sponsored the 2012 institute together with the National Heritage Language Resource Center (NHLRC), aims to prepare a cohort of university graduates who have studied a language deemed critical to U.S. competitiveness and security in sufficient depth such that they achieve an advanced level of mastery. An “advanced level” is usually defined with reference to proficiency level descriptors used by the American Council on the Teaching of Foreign Languages (ACTFL) and the Interagency Language Roundtable (ILR), namely ACTFL Advanced or ILR 2. The question then arises: outside the 26 Flagship programs established in American universities, how can the general population of language learners be supported and motivated to achieve this level of proficiency?

Attitudes and Beliefs of Teacher Candidates Regarding Heritage Language Maintenance
Authors: Szecsi Tunde , Szilagyi Janka , Giambo Debra A.
Published: February 2021

This paper reports on the findings of an investigation that explored teacher candidates’ (TCs) attitudes and beliefs about heritage language (HL) maintenance and variables that may predict their attitudes and beliefs. The participants were 270 TCs in Southwest Florida who completed an on-line survey with Likert-type statements and open-ended questions. Quantitative data was analyzed using factor analysis followed by linear multiple regression analyses. The constructs of TCs’ attitudes and beliefs toward HL maintenance were used as dependent variables in the multiple regression models. The level of preparation in multicultural and bilingual education was a statistically significant predictor of TCs’ views in regard to active teacher practices to maintain HL, benefits of HL at school, and the role of the schools. TCs’ ability to speak more than one language was found to predict their attitudes and beliefs about the benefits of HL at school. In
addition, experiences with diverse cultures and languages outside the U.S. influenced TCs’ attitudes toward bilingualism. The qualitative analysis of TCs’ responses to the open-ended questions showed increased awareness of HL maintenance for TCs at the end of the teacher education program compared with those at the beginning. However, descriptions of teaching strategies in HL maintenance indicated TCs’ limited understanding of appropriate ways for supporting the HL. This gap between awareness and expected teacher behavior suggests the need for further preparation in the area of HL support.

INTRODUCTION Outcomes for hepatectomy for breast cancer metastasis and sarcomatous disease processes are not well defined in literature. We sought to use a national database to identify outcomes in these patients compared to subset of patients more well studied in literature – primary Hepatocellular cancer patients and patients with colorectal metastasis. METHODS We identified patients undergoing major hepatectomy (≥ 3 segments) for primary hepatocellular cancer (HCC), sarcoma metastasis, breast cancer metastasis, and colorectal metastasis using NSQIP database. The Primary outcome measure was 30-day mortality. Secondary outcome measures were 30-day readmission and complication rates. RESULTS A total of 5580 patients underwent major hepatectomy during the study period. Patients who underwent hepatectomy for breast cancer metastasis had higher incidence of in-hospital complications (37%) compared to sarcoma (29%), colon (26%), and HCC patients (24%) and 30-days readmission rate (37% vs. 29% - sarcoma vs. 26% - colon vs. 25% HCC). There was no difference in 30-days mortality among the groups. CONCLUSION Patients undergoing major hepatectomies for breast cancer metastasis and sarcoma are more likely to have adverse outcomes than compared to their counterparts. This difference highlights the lack of experience in managing breast cancer and sarcoma with metastatic disease to the liver. This also highlights the difference in tumor biology among all the lesions we studied. An extensive discussion should take place when dealing with breast and sarcoma lesions in the liver because of these outcomes.
BLAS IV: A BLAS for Rk Matrix Algebra
Authors: Shaeffer John
Published: February 2021

Basic Linear Algebra Subroutines (BLAS) are well-known low-level workhorse subroutines for linear algebra vector-vector, matrixvector and matrix-matrix operations for full rank matrices. The advent of block low rank (Rk) full wave direct solvers, where most blocks of the system matrix are Rk, an extension to the BLAS III matrix-matrix work horse routine is needed due to the agony of Rk addition. This note outlines the problem of BLAS III for Rk LU and solve operations and then outlines an alternative approach, which we will call BLAS IV. This approach utilizes the thrill of Rk matrix-matrix multiply and uses the Adaptive Cross
Approximation (ACA) as a methodology to evaluate sums of Rk terms to circumvent the agony of low rank addition.
Adaptable Nonstandard FDTD Schemes for the Precise Evaluation of Electrostatic Fields
Authors: Ohtani Tadao , Kanai Yasushi , Kantartzis Nikolaos
Published: February 2021

The reduction of the total computational overhead in the design of complex geometries, such as modern aircrafts, is a very challenging problem, particularly when electrostatic
fields (ESF) for lightning protection, are considered. To this aim, an efficient ESF evaluation scheme, based on the nonstandard finite-difference time-domain (NS-FDTD) method, is proposed. Combining the total-field/scattered-field (TF/SF) concept with a distinct sine-wave form, the novel technique cancels the accumulative errors caused by the static field component. Numerical results reveal that the featured method enables the use of high-frequency discretization models to ESF problems, with notable accuracy and seriously decreased design costs.
Shape Synthesis of Multi-mode Dielectric Resonator Antennas Using Characteristic Modes
Authors: Yang Binbin , Eroglu Abdullah , Adams Jacob
Published: February 2021

This paper demonstrates a shape synthesis technique for multi-mode dielectric resonator antennas using binary genetic algorithm and characteristic mode analysis. The cost function for the synthesis process is defined from characteristic modal parameters, such as modal quality factors and self-resonance frequencies. Since only modal parameters are involved in the cost function, the shape synthesis process is made independent of feeds. In the paper, we demonstrate the shape synthesis of a DRA with three self-resonant modes at 3 GHz.

Nested Kriging Surrogates for Rapid Multi-Objective Optimization of Compact Microwave Components
Authors: Pietrenko-Dabrowska Anna , Koziel Slawomir
Published: February 2021

A procedure for rapid EM-based multi-objective optimization of compact microwave components is presented. Our methodology employs a recently developed nested kriging
modelling to identify the search space region containing the Pareto-optimal designs, and to construct a fast surrogate model. The latter permits determination of the initial Pareto set, further refined using a separate surrogate-assisted process. As an illustration, a three-section impedance transformer is designed for the best matching and minimum size. The set of trade-off designs is produced at the low computational cost of only a few hundred of high-fidelity EM simulations of the transformer circuit despite a large number of its geometry parameters.

Published: February 2021

Multi-objective design optimization environments are used for electric vehicles and other traction applications to arrive at efficient motor drives. Typically, the environment includes characterization modules that involve the use of Electromagnetic Finite Element and State-Space models that require large number of iterations and computational time. This work proposes the utilization of a Taguchi orthogonal arrays method in conjunction with a Particle Swarm Optimization search algorithm to reduce computational time needed in the design optimization of electric motors for traction applications. The effectiveness of the Taguchi method in conjunction with the optimization environment is demonstrated in a case study involving a prototype of a Synchronous Reluctance Motor drive system.

Published: February 2021

Wind affects functional state and health of human beings. Physical activity mitigates the risk of hypothermia, but not the discomfort felt in cold winds. Moreover, there appears a risk of body cooling and frostbite. This study aimed to assess the risk to health of a human being associated with the wind chill factor index in the various climatic zones of a Russian region. The calculation relied on the mean monthly daily temperature and wind speed values, minimum temperature and maximum wind values registered in the subarctic and continental climate zones during the two climatological normals determination observation periods, 19611990 (second period) and 1991–2020 (third period). In the third period, a significant decrease in wind strength was registered in the subarctic (8 months) and temperate continental (9 months) climates. The mean monthly temperatures increased in April by 3.5 °C (p = 0.006), April–June by 4.05 °C (p = 0.001) and 3.9 °C (p = 0.001). The maximum wind in the subarctic climate did not change, in the temperate continental zone it decreased within 9 months; the minimum temperature increased in 4 and 1 months. In the subarctic zone, the mean temperature and wind values made the ambient conditions uncomfortable for 6 months (versus 7), with one characterized as "extremely cold"; the cold exposure risk decreased during the "very cold" period; in the temperate climate zone, the potentially uncomfortable conditions period lasted for 4 months (versus 6). With wind at the maximum and temperature at the minimum, in the subarctic climate, the weather remained severe for 8 months a year in each of the determination periods ("uncomfortable, chilly" — 2 months, "cold, skin surface hypothermia" — 1 month, "extremely cold, possible hypothermia of the exposed parts of the body in 10 minutes" — 5 months); in the temperate continental climate zone, it was severe for 5 months of each year ("uncomfortable, chilly" — 2 months, "cold, skin surface hypothermia" — 3 month).

Published: February 2021

Senior High School (SHS) teachers are at the forefront of providing quality and innovative education for students who would either enter the world of work or pursue tertiary education. Therefore, their commitment and dedication to their craft should be carefully delved into, and one of the dimensions where they manifest such attributes in the teaching profession is the level of their engagement in the delivery of instruction. Hence, this study was conducted in order to assess the engagement of selected SHS teachers in Batangas Province during the academic year 2019-2020. It specifically covered the extent of teachers’ engagement as characterized by their vigor, dedication and absorption, and explored on the factors that contribute to their engagement as to school policy, school culture, teacher empowerment, and interpersonal relationship. It also analyzed how teaching engagement is manifested in terms of cognitive, physical, and emotional domains and looked into the sources of burnout in teaching, with the end view of proposing effective measures to foster effective teaching engagement. The descriptive method of research was utilized in the study with the use of a questionnaire as the main data gathering instrument. Gathered data were further enriched through the focus group discussion and interviews. Respondents included 85 school heads and 322 SHS teachers in the province of Batangas. The statistical tools utilized were weighted mean, ranking, and t-test. Results from the findings revealed that teachers manifest moderate engagement in vigor, dedication, and absorption. It was also revealed that school policy and administration moderately contribute to teachers’ engagement, while school culture and interpersonal relationships greatly contribute to their engagement. On the other hand, school heads assessed that teacher empowerment greatly contributes to engagement, while teachers claimed that this factor affects their engagement moderately. Comparison on the assessments between the two groups of respondents revealed they concurred in vigor, absorption, teacher empowerment, and interpersonal relationship, but differed in their assessments on dedication and school culture. Moreover, work overload issues, absence of an awards and recognition system, and big class sizes were found to be the primary sources of teachers’ burnout.

Irrigation is one of the key strategies for agricultural transformation and commercialization processes in Ghana and elsewhere in the developing world. This is because irrigation provides opportunity for extended agricultural production, particularly in areas characterized by short duration and low intensity rainfall regimes. Thus, irrigation provides a unique opportunity for the poor, who are mostly smallholder farmers to urge themselves out of poverty. In order to enhance and sustain the benefits from irrigation, there is the need for careful and rigorous study to understand the socio-economic underpinnings of irrigation participation. This paper sought to investigate the factors that influence participation in irrigated agriculture and its effects on livelihoods. The method of analysis involved an estimation of treatment effect model. The study relied mainly on primary data collected from 304 respondents randomly sampled across four irrigating communities in the Bawku West District of Ghana. The empirical results show that age, marital status, market availability, extension contact and farm size significantly influence farmers’ decision to participate in irrigated agriculture. Participation in irrigation positively affects livelihoods development. However, the benefits of irrigation are likely to be offset by large household sizes, source of water for irrigation and education. The study recommends that farmers must be assisted with improved technologies in irrigated agriculture supported by gender sensitive extension services to ensure effective technology use. There is also the need for improved access to markets.

The Ghana Irrigation Development Authority (GIDA) is a public sector organization established to promote agricultural growth through the provision of irrigation infrastructure and other agricultural water management techniques. Irrigated agriculture in Ghana is categorized into formal, informal or smallholder and large-scale commercial irrigation. Over the years, irrigation development in the country has been faced with a number of challenges, which necessitated the development of the National Irrigation Policy, Strategies and Regulatory Measures and the Ghana Agricultural Water Management Pre-Investment Reform Action Framework. A number of factors affecting irrigation development in the country include lack of capital, commitment by successive governments, cost of energy, access to land and credit, lack of technical know-how and encroachment, among others. Analysis of budget provided by government for public irrigation development was carried out using simple linear regression. Results indicate a bright prospect of irrigation development, with reforms under implementation. A minimum of GHS 633.43 million is required for release into the sub-sector by government together with investments from private sector in the next ten years to shift the balance towards positive growth. To solve the problem of inadequate funding of the sub-sector activities, it is recommended that the GIDA collaborates with Development Partners to fund projects and activities in line with their objectives. GIDA should develop effective programmes for building capacity of contractors involved in development of infrastructure. GIDA should deepen its collaboration with private investors under PPPs and convert electric and diesel/petrol powered irrigation pumps to solar powered ones.

Sediment delivery from the Tono Reservoir watershed in the Upper East Region of Ghana is of major concern, necessitating the need to estimate the rate of siltation of the reservoir. This study determined the current volume of silt in the reservoir, mapped landcover changes using Landsat images and employed Water Erosion Prediction Project (WEPP) model, to simulate hydrology and sediment dynamics for three landuse/landcover scenarios. The Geo-spatial interface for WEPP (GeoWEPP) was used to characterize upland overland flow elements based on their landuse/landcover, soil, and slope profiles. Using characteristics obtained from GeoWEPP as inputs for the WEPP model runoff fluxes, soil loss rates, and sediment delivery ratio (SDR) for three environmental scenarios: landuse/landcover with agricultural lands under fallow tilled management (Scenario 1), landuse/landcover with agricultural lands under corn, soybean no till management (Scenario 2), landuse/landcover with non-agricultural lands under shrub-perennial (Scenario 3) were estimated. Over the simulated 29-year period; runoff depth, soil loss rate and SDR were estimated to be 118.4 mm, 22.8 t/ha, and 0.68 for Scenario 1; 94.6 mm, 2.8 t/ha, and 0.31 for Scenario 2; and 57.7 mm, 0.6 t/ha, and 0.92 for Scenario 3. Shrubland had decreased by 8 %, bareland area had increased by 9.1 %, and the reservoir area had also decreased by 3.7 %. The study indicates landuse/landcover change impacts significantly on land degradation and hydrology of the Tono reservoir and subsequently accounts for the reduction in reservoir capacity by about 1.74 % on annual basis observed through the bathymetric survey.

The increase in student population has led to a corresponding increase in the generation of waste on the Campus of the Kwame Nkrumah University of Science and Technology. Composting of the biodegradable portion of waste is seen as a better option to reduce the volume of waste and manage it at the same time. This study hence aimed to investigate the effect of some bulking materials on the quality of compost after the decomposition of the biodegradable portion of the waste generated. Bin composting was employed for this analysis. Composting was conducted over a 60 -day period at the sewage treatment plant on the KNUST Campus. Wastes comprising of food waste, sawdust, and grass clippings were mixed in ratios of 1:1, 1:2, and 2:1 (v/v) ratio for sawdust/food waste (SSD 1:1, SSD 1:2, SSD 2:1) and grass clipping/food waste (SGC 1:1, SGC 1:2, SGC 2:1). Turning of compost was done manually at three days interval during which the volume was also recorded. Temperatures were taken on daily basis, three times within a day at 8 am, 12 pm and 4 pm respectively. Volume of all bins reduced as percentage organic matter decreased leading to an increase in percentage ash to between 39. % and 64.5 %. Percent organic matter loss was highest in the grass clipping/food waste treatments compared to the sawdust/food waste treatments. By the end of eight weeks of analysis, the grass clipping/food (SGC 1:1, SGC 1:2, and SGC 2:1) waste formulations were seen to decompose faster than the sawdust/food (SSD 1:1, SSD 1:2, and SSD 2:1) waste formulation. The grass clipping/food waste ratios (especially the SGC 2:1) therefore gave better compost in terms of the quality since rate of decomposition was faster compared to the sawdust/food waste.
Agricultural Output and Economic Growth Nexus in Ghana

Published: February 2021

This study explored the relationship between agricultural output and economic growth in Ghana from 1960 to 2016 using monthly data on the Gross Domestic Product (GDP), Gross Capital Formation (GCF), agriculture and inflation. Despite several agriculture-led economic growth programmes that have been implemented by successive governments, including the very recent “Planting for Food and Jobs” to create jobs and boost economic growth, the contribution of agriculture sector output to the Ghanaian economy has been on the decline. The estimation results from the Johansen Maximum Likelihood co-integration and the Vector Error Correction Model (VECM) support evidence of a long-run relationship between agricultural output and economic growth in Ghana. Specifically, the co-integration test reveals that agricultural output and economic growth were found to be moving together in the long run. The Granger causality test showed a unidirectional causal relationship running from agricultural value-added to economic growth but no causal flow from general economic growth to agriculture. This indicates that agriculture is still an engine of economic growth in Ghana and hence requires pro-poor policies to address the numerous challenges.
