Logistics and Supply Chain Management Efficiency Strategy for Ghana’s Mining Industry
Authors: Yaping Qu , Bossman Mary 
Published: April 2021

The invaluable contribution of the mining industry in any country’s economy is widely acclaimed and thus not far-fetched. In as much as the mining industry contributes hugely to economic and social growth, its operations are characterized by complex supply chain processes that are relatively capital and cost intensive, and technologically sophisticated to manage. Unfortunately, firms in the mining industry especially for developing countries tend to focus more on procuring modernized equipment and technologies to carry out the complex processes of mining operations to the detriment of applying logistics optimization models.
This research project therefore seeks to analyze the logistics and supply chain operations of mining companies in Ghana, identify the challenges and inefficiencies associated with these operations and their underlying causes, and recommend logistics and supply chain management design, modelling and analysis tools to optimize. With the help of secondary data collected from books, journals, which were further depicted in graphs and tables, the Microsoft Excel Solvers for Vehicle Routing Problem (VRP, Version 3.42), with an embedded Bing Map Key License was used to illustrate and derive optimal solutions for the transportation efficiency of mining firms in Ghana.
The study revealed that the mining industry in Ghana is confronted with supply chain issues like poor road networks in mining communities, variable lead time and exchange rate, strict governmental laws, violent clashes over land royalties, high transport cost due to bad roads, unreliable lead times (caused by port delays), unavailability of local suppliers of international standards, and policy restrictions as the main challenges to supply chain. Clearly, the policy implication emanating from this study is that mining firms in partnership with transport services firms in Ghana must adopt an efficient service delivery and optimal transportation cost reduction strategies, which is designed with the Vehicle Routing Problem Optimization Model in order to benefit mutually in gaining competitive advantage.
Chlamydia trachomatis and Neisseria gonorrhoea Co-Infection Among Patients Attending a Teaching Hospital in Nairobi County: A Retrospective Study
Authors: Mulakoli Festus 
Published: April 2021

Background: Chlamydia trachomatis and Neisseria gonorrhoea are microbes that have been associated with urethritis in both male and female genders, which often may lead to complicated conditions such as pelvic inflammatory disease (PID) and infertility globally among others health complications. In Kenya and other developing countries, sexually transmitted infections associated with Chlamydia trachomatis and Neisseria gonorrhoea still pose a challenge in public health.
Methods: A retrospective study was conducted by reviewing laboratory data from Jan 2018 to Dec 2018 to estimate the prevalence of C trachomatis and N gonorrhoea coinfections in patients attending a tertiary institution and its satellite clinics spread across the country. A total of 1228 patient’s data aged 3-69 years was reviewed; with age, gender and Chlamydia trachomatis and Neisseria gonorrhoea status being analyzed.
Results: A total of 1228 patients who visited the hospital in 2018 had their urine samples being tested for Chlamydia trachomatis and Neisseria gonorrhoea by use of a PCR technique. Majority of the patients were males (63.7%). The patients who tested for Chlamydia trachomatis and Neisseria gonorrhoea had an average age of 34 years (range: 3–69 years). Of those 1.4% tested positive for both Chlamydia trachomatis and Neisseria gonorrhoea infections, and males were more infected than females (1.1% vs 0.3).
From the information gathered during the study period, the proportion of patients with Chlamydia trachomatis infection was (16.1 %) (95 % CI 9.5, 17.9), and with N. gonorrhoea infection was 5.4%. Coinfection was highest among sexually active group that is those aged between 21 years to 40 years.
Conclusion: The prevalence of C. trachomatis is significantly high among male patients. We recommend the implement a molecular screening for Chlamydia trachomatis and Neisseria gonorrhoea to identifying asymptomatic female cases. This study further provides evidence on the importance of contact tracing in the management of Chlamydia trachomatis and other STIs. There is an urgent need for studies designed to investigate the prevalence and risk factors of Chlamydia trachomatis and Neisseria gonorrhoea among female patients who are majorly asymptomatic in Kenya.

Authors: Amanya Martin , O. Ajayi Clement , Natukunda Bernard , G.Agaba Amon 
Published: April 2021

Introduction: Despite the efforts of governments and health organisations to eradicate malaria, it is still endemic in sub-Saharan Africa and this could be due to cost of antimalarial drugs, resistance to these drugs and climate change among others. Traditional medicine practitioners and scientists have started developing antimalarial drugs from medicinal plants among which is ARTAVOL®. ARTAVOL® is a herbal product that is used to prevent malaria in some communities in Uganda, however, its prophylactic effects on Plasmodium berghei infected mice has not been established yet.
Methods: The infusion of ARTAVOL® powder was prepared, cooled, filtered, concentrated in vacuo at 55 0C and freeze-dried. The freeze-dried extract was reconstituted with distilled water for antimalarial using prophylactic model mice. Thirty-six mice were randomised into 6 groups of 6 mice each. Groups I to III mice were orally administered with the extract at 15 to 60 mg/kg/day while group IV received Pyrimethamine (1.25 mg/kg) while groups V and VI (uninfected) received 0.2 mL distilled water for seven days before the inoculation of Plasmodium berghei ANKA parasites on day 7 (D7). The parasitaemia levels were examined after 72 hours using standard procedure and blood collected through cardiac puncture for haematological study.
Results: The Lethal Dose (LD50) of the crude ARTAVOL extract was greater than 5000 mg/kg. Also, there was calmness and paw licking immediately after dosing which stopped after few minutes. Significant reduction in parasitaemia level was observed in all test doses when compared with negative control. At 30 mg/kg, the extract gave 62.9% suppression, which was not significantly different from that of 60 mg/kg (68.7%) on day 3. On day 5, the extract gave 62.3% and 66.4% Suppressions At 30 And 60 Mg/Kg That Were Not Significantly Different From Each Other. A Dose Dependent Reversal of Hematocrit (HCT) reduction was observed at the 3 dose levels but their parameters did not show any significant difference when compared to the normal group but significant when compared with negative control.
Conclusion: ARTAVOL® extract has shown a dose dependent reducing effect on the level of parasitaemia in P.berghei infected mice; it is acutely safe and has ability to increase RBC counts.

Authors: Buuri Martin , Gicheru Michael , Mutiso Joshua , Mulakoli Festus 
Published: April 2021

Although fungi are known to be less pathogenic and mostly saprophytic in their nature as compared to other groups of microbes, those that produce aflatoxin have been associated with severe human disease. An example of such disease is Aflatoxicosis caused by soil-borne pathogenic fungi of the species Aspergillus parasiticus and Aspergillus flavus. They produce a mycotoxin substance that is carcinogenic to the human liver with severe outcomes. The objective of this study was to determine urinary aflatoxin levels among the residents of Makueni County, previously affected by Aflatoxicosis.
This was a cross-sectional study that involved the use of primary data collected from 106 participants. The method for data collection included a structured questionnaire and the collection of the urine samples for aflatoxin M1 analysis at Bora Biotech Laboratories LTD. The urinary levels of AFM1 were detected by use of an ELISA kit. Data was entered in SPSS and analysed through Chi-Square for the association.
The study participants, including both male and female, had an age of between 15 and 91 years and with an average age of 41±18. Out of the 106 study participants, n=68 (72%) were females and n=26 (28%) were males. Majority of the study participants were with a median age of 24 years old. AFM1 levels were detected in 99.1% % of all urine samples at a range of 25-2337 pg./ml. The mean and median concentration of AFM1 in urine was 637.6 ± 512.7and 525 pg./mL, respectively.
The results of this study provide information on the current situation of aflatoxin exposure. From what is evident from our study a lot needs to be done to mitigate on the long-term effect of this high exposure. Therefore, the study encourages the concerned ministry to have a broader focus on the extent of aflatoxin food contamination from this region plus other regions across the country.

The Concept of Waqf-Syirkah for Community Food Security
Authors: Wildana Muhammad Dandy Alif , Kafabih An’im 
Published: April 2021

Abstract
Food is essential for human survival, and ensuring its availability is critical. Waqf is present as one of supporting institutions that supports food security. This paper aims to see how waqf can contribute to the food security of a community. Waqf, in its sense is an Islamic philanthropic institution that focus on welfare of Muslim. As a Muslim, it is important to safeguard one’s life as stated in Maqasid As Shariah. This paper employs systematic literature review to see the contribution of waqf through syirkah (partnership) for community food security. Syirkah plays its role as a connector between waqf and food security, with farmers at its spearhead. Syirkah is chosen because it is compatible with farmer’s business and waqf may serve to their business sustainability in general, and farmer’s livelihood in particular. The ultimate goal of this concept is to achieve stability in the supply of staple food which leads to its price stability, hence staple food is available and accessible to all. Furthermore, the stability achieved will reduce the burden of government to provide staple food in times of crisis and to promote welfare and better social cohesion of a community.
Control of a Four-wire Hybrid Prosumer Converter for Balancing Utility Grids
Authors: Łukasz Kwaśny , Zieliński Dariusz 
Published: April 2021

Abstract
The paper presents the project of the power electronic AC/DC converter operating under a multiresonant control algorithm for prosumer applications. This design allows independent control of active and reactive power for any or each phase. Both the converter and its algorithm are based on a three-phase converter of four-wire topology (AC/DC 3p-4w) with a DC bus, which couple the converter to a renewable energy source and energy storage. Further, model and simulation tests were carried out in the Matlab-SIMULINK programming environment. The results obtained indicate that operation with deep unbalances and powers of opposite signs in individual phases results in current variations (oscillations) in the DC line, which is a significant limitation, and it can be concluded that the level of asymmetry should be limited to the level acceptable to the energy storage device.
A Different Perspective on Canadian History: The Canadian Wing of the Art Gallery of Ontario’s New Design
Authors: Sevcik Jackie 
Published: April 2021

The issue of representation within the grand Canadian historical narrative is a topic that re‐opens previous notions about the accepted version of the Art Historical canon. While there are many aspects of Canadian Art History that are celebrated as true notions of national identity, there are many indigenous groups and ideas that do not meet the criteria to be included in the canon and are thus, not represented. This paper examines the contemporary Canadian Wing at the Art Gallery of Ontario (AGO) and will focus on showing the changes made to the gallery and how this will help Canadians understand what it means to be Canadian. What is interesting about this newly renovated wing is that the curatorial staff has successfully managed to show Canadian history from a contemporary perspective. By choosing to recognize the importance of different aspects of Canadian history to the understanding of Canadian identity, the AGO takes old practices and turns them into new traditions.

Published: April 2021

Background: The Zanzibar Ministry of Health identified access to ultrasound (US) as a system priority due to limited diagnostic imaging capacity and consequent impact on patient care and requested a needs assessment in this regard. As a result, the objective of this study was to assess diagnostic imaging capacity focusing on ultrasound in Zanzibar, including health care providers’ (HCPs) current training, use, and barriers to implementation. Methods: A previously published ultrasound needs assessment survey was modified and administered on-site at the eight public hospitals in Zanzibar among a convenience sample of HCPs. Demographics, perceived US needs, current training and practice, and availability of specialty support were assessed. HCPs also completed focused personal interviews (FPIs) to explore experience with training, interests, and barriers to ultrasound. On-site diagnostic imaging modalities were assessed. Results: There were nine ultrasound machines present at six of the eight public hospitals assessed. All had x-ray, but only one had a CT scanner and a radiologist. There was no MRI capacity at the hospitals assessed at the time of the study. Survey data among 40 participants revealed that prior experience with POCUS was limited with only 10% reporting any prior ultrasound training or experience. The majority of those surveyed (72%), indicated a ‘high’ interest in learning ultrasound. Of those reporting interest in POCUS applications, obstetrics was the most often cited (70%). Lack of ultrasound machines (40%) and educators (28%) were identified as the greatest barriers. Conclusion: HCPs in Zanzibar have limited access to diagnostic imaging, including ultrasound, and expressed a high level of interest in learning point-of-care ultrasound. A shortage of machines and educators are the main barriers to widespread use. Obstetrics is the application for which ultrasound is currently most used and is the application HCPs are most interested in learning. Equipment and educational support for a POCUS program could improve care by increasing access to diagnostic imaging.
SOVIET REPRESSIONS AGAINST THE CLERGE OF THE GREEK CATHOLIC CHURCH IN 1944–1947 (ON THE EXAMPLE OF FR. IVAN KOTIV’S BIOGRAPHY)
Authors: Haliv Mykola , Ohar Anna 
Published: April 2021

Summary. Based on the prosopographic approach and analysis of the Fr. Ivan Kotiv biography the article studies the forms and methods of Soviet repressions against the Greek Catholic clergy. The purpose of the article is on the example of the relations of the Soviet special bodies with Fr. Ivan Kotiv to analyze and cover the repressive activities against the Greek Catholic Church in 1944–1947. The research methodology is based on prosopographic approach, principles of historicism, scientific, authorial objectivity, application of general scientific (deduction, induction, analysis, synthesis, generalization) and special historical (historical-genetic, historical-systemic, historical-typological) methods. The novelty of the study is that for the first time in Ukrainian historical science an attempt has been made to shed light on the repressive activities of the Soviet authorities against the Greek Catholic clergy through the prism of a prosographic analysis of the activities of Fr. Ivan Kotiv, one of the informal leaders of the Greek Catholic clergy in the liquidation of the GCC. The Conclusions. Thus, on the example of the relations of the Soviet special bodies with Fr. Ivan Kotiv analyzed and covered the repressive activities against the GCC in 1944–1946. In our opinion, the repressive policy of the Soviet authorities towards the clergy of the GCC during the outlined period can be divided into several stages: 1) stage of "soft pressure" (August 1944 – March 1945), which was characterized by careful study and analysis of the internal situation of the GCC, personality traits of leading figures among the Greek Catholic clergy, gradual propaganda and intelligence training of the Union Church to join the ROC, dissemination of rhetoric individually and through the media and study the clergy the idea; 2) the stage of organizational and repressive pressure (April 1945 – March 1946), which was marked by the arrests of the top of the GCC, the creation and operation of the CIG, neutralization of opposition attempts led by K. Sheptytsky and I. Kotiv to conduct special operations to "reunite" churches; 3) the stage of total repressions against the clergy, which did not recognize the decisions of the Lviv Pseudo-Council (March 1946 – May 1947). In fact, all these stages are quite clearly traced in the relationship of Fr. I. Kotiv with the Soviet authorities, and thus his activity in the period under study is quite representative and prosopographically relevant for understanding the complexity of the GCC in the restoration of the Soviet totalitarian regime in the Western Ukraine in the first postwar years.

Authors: Rohozha Mariya 
Published: April 2021

Summary. The purpose of the research is to reveal the peculiarities of the naturalist M.I. Havrylenko (1889‒1971) research work during the 40’s ‒ 50’s years of the twentieth century; to show his personal ability to study nature in terms of the tendency attitude to the scientist in the postwar period, due to the peculiarities of the biography. The research methodology is based on the principles of historical reliability, objectivity, systemcity, multifactoriality, scientificity and comprehensiveness; use of general scientific research methods (analytical, synthetic, logical, classification); historical (problem-chronological, comparative-historical, historical-genetic, retrospective) and interdisciplinary. The scientific novelty lies in the fact that it is the first time in modern history the scientific heritage of the zoologist M.I. Havrylenko on the basis of his published works during the 40’s ‒ 50’s years of the twentieth century is learned. It is established that, despite the negative attitude of society to the scientist, he continued working productively. To form scientifically reliable results of studying different classes of animals, he used the methods of zoology, as well as botany, anatomy, osteology, physiology, physical geography, geology, paleontology, ecology, biocenology and other sciences. Conclusions. After almost twenty years’ study of the vertebrate fauna of Poltava region, the scientist obtained several fundamental results: 1) identified changes in species quantity, 2) deepened the knowledge of little-known animal species, 3) studied the herpetofauna of Poltava region, thus expanding his own scientific interests, 4) clarified the issue of zoogeography of black grouse in historical retrospect, 5) conducted a comparative species analysis of birds of the genus Ocheretyanka for different ecotopes in the biogeocenosis, 6) conducted an analysis of new and little-known bird species in the Poltava region in the space-time continuum (1929‒1958), 7) continued the formation of a unique ornithological collection, importantly. In general, it is emphasized that the scientific progress of the zoologist M.I. Havrylenko during this period was productive and effective.
