Effect of Combining Maize Straw and Palm Oil Fuel Ashes in Concrete as Partial Cement Replacement in Compression
(2021) Odeyemi S.O., Abdulwahab R., Giwa Z.T, Anifowose M.A, Odeyemi O.T., Ezenweani C.F
The high energy consumption connected with cement manufacturing, as well as the depletion of limestone resources and the release of carbon dioxide, which contributes to global warming, are all important issues that must be addressed. Partially replacing cement with agricultural wastes in concrete, which reduces cement output, is an innovative solution to this problem. This paper examined the effect of combining Palm Oil Fuel Ash (POFA) and Maize Straw Ash (MSA) as partial replacement of cement on the compressive strength of Grade 20 concrete at 0 - 30 % POFA and 0 - 30 % MSA using Historical data under the Response Surface study in Design-Expert software. The concrete cubes were tested at 7, 28, and 56 days of curing. It was discovered that there was a decrease in the compressive strength of the concrete with the percentage increase in the quantity of the POFA and MSA for all the curing days considered. However, there was a progressive increase in the compressive strength with an increase in the days of curing. The optimum combination of percentages of POFA, MSA and cement that gave a strength greater than the target compressive strength of 20 N/mm2 in 56 days is 30 % POFA and 16.6 % MSA and 53.4 % Cement at 0.58 water-cement ratio.

Community-Based Strategies to Improve Primary Health Care (PHC) Services in Developing Countries. Case Study of Nigeria
(Scient Open Access Journal: Journal of Primary Health Care and General Practice, 2020-02-06) Oluwasogo A. OLALUBI; Ibrahim Sebutu BELLO
Primary Health Care (PHC) remains the minimum package of healthcare that should be provided to every individual and community across Nigeria's Health System. The aim is to improve relatively the health status of the nation by ensuring the provision of healthcare services to people in rural areas which is indicated by reduced mortality and morbidity and improved survival rates in such communities. However, the situation of health status in Nigeria has not yet attained the desired level. Data shows that as of 2015, the country recorded 814 maternal deaths / 100,000 live births which put her in the same category as the poorest countries in the world such as Chad, Niger and Somalia among others. Furthermore, Nigeria’s health profile reveals that 2,300 under-five children and 145 women of childbearing age die every single day. Moreover, malaria, pneumonia, diarrhoea and other preventable infectious diseases remain the major causes of under-five deaths in Nigeria. Given these problems faced by PHC in the country, there is an urgent need for ‘‘one health’’ approach integrating the principal stakeholders, the current Minister of Health, state commissioners for health, all 774 Local Government chairmen as well as the National Postgraduate Medical College of Nigeria (NPMCN) to revisit manpower need of PHCs and secondary healthcare facilities. There is also the need for policies for restructuring, leadership and running of these PHC institutions. Promoting health and prolonging life requires prompt detection and effective management of common communicable and non-communicable diseases cases which can only be achieved through a robust primary healthcare facility. A national health insurance system that provides cover for vulnerable special groups, aged, young adolescents, school children, as well as pregnant mothers is a necessity towards reducing inequality in access to basic primary healthcare. This will reduce dependence on out-of-pocket spending and improve access to healthcare services.

Values and Hopes of Ebola Vaccines Mass Immunization Programs and Treatments Adoption and Implementation Benefits in Africa
(International Journal of Vaccines and Vaccination, 2015-11-06) Ernest Tambo; Chidiebere EU; Oluwasogo A. Olalubi; Isatta W; Jeannetta KJ; Jeane YN
The potential benefits of safe, effective and cost effective Ebola vaccines and massive population-based immunization and treatment can be easily demonstrated by the unprecedented Ebola outbreak consequences that raged West Africa and intimidation the international public health security. Effective community-based health programming and contextual understanding have shown to be of tremendous benefits of global poliomyelitis immunization initiative. Africa fertility rate is among the highest in the world and projected growth over next 40 years, from 1.1 billion to 2.4 billion by 2050. It has become clear that the lack of effective Ebola immunization programs and management logistics in both vulnerable populations and international travellers was complicated by weak health planning and epidemics preparedness. Moreover, poor prognosis and late local, regional and international response led to preventable toll of over 27,609 cases and 11,261 deaths been recorded in West Africa recently. As Ebola still represents a common threat in Africa and threatening the global community; this article reports a cumulative survival rate varying between 37- 66% in West Africa with the highest in Sierra Leone of 67% in contrast to 26% in DR Congo with the highest cumulative frequencies of seven of Ebola resurgence episodes from 1977-2014, and Uganda five episodes from 2000-2012. But what exactly triggers to those Ebola patients fortunate enough to survive is still to be elucidated. West Africa has recorded a cumulative fatality rate ranging from 34- 63 %. Understanding the benefits of Ebola immunization should be of importance and could provide inklings into Ebola’s weakness in such dearth of local medical and healthcare delivery, intense global travel and food insecurity systems. Hence, development and effective deployment of massive population-based Ebola immunization program and travel medicine policy on prevention and control measures should be a major priority post-Ebola emergency response directed to curb and to eradicate the threatening Ebola outbreaks. In addition, development of evidence-based innovative community-based primary healthcare services, functioning delivery mechanisms, other public health interventions surveillance and recovery packages. Hence, support in improving safety and healthy living in achieving the national / regional growth, sustainable development goals and global health security.
