    The interpretation of two resistivity curves over Iyakpi town within geologic terrain often referred to as Ajali formation which bears false-bedded sandstone with associated clay and shale intervals in the bottom section indicates that the area has an abundant groundwater potential. Existence of productive borehole in the study area was field-confirmed. The study area is said to have a standing history of abortive boreholes, resulting from failed drilling attempts. No dug well was sited in the community. The study showed that the main lithologic units penetrated by the sounding curves are laterite, sandstone, sandstone (dry with some clay/shale). This study revealed the possibility of having a maximum drill depth to water table of 260 m (865.80 ft)

    This paper reuiews the policy framework for Nlgelian agriculture and gauges Its Impact plior to and since the commencement of economic deregulation. It investigates the prospects, analyses tile constraints and ouUlnes a feasible strategy for sustaining ag~icultural growth In a deregulated enabling environment. The paper notes that In the period, 1970 to 1982, the deterioration In ag~icultural pe1jormance In Nlge1ia was the result not only of extemal shocks and erwironmental and/or edaphfc foctors, but of distorted policy pursuits which created clislncentiues for farming. Howeuer, following attemptS to deregulate the economy with the adopUon of the Structural Adjustment Pl:o!P·amme In 1986 and the consequent eff01t to get price lncenUues right for agriculture, there was some Improvement in ag~icultural performance. It Is noted that agricultural sector growth has recently been lwmpered by increased costs 01ising mainly from genera/deregulation. An lnuestlgatlon of the resource base and prospects shows that ag~kulture can contlibute more to g~·owth than In recent years. But success wlll require engendering a conducive enabling environment and Incentives, avaliC!bility of technology and Inputs as well as Infrastructure. This calls for an oction plan which glues the prluate and Informal sectors bigger roles In the execution of development prog~·ammes. In addition, the public section would need to refocus current policies and priolitles with more uigorous implementation of known successful approoches based on factor endowments for stimulating growth

    The prevalence of pulmonary embolism in non-hospitalised de-isolated patients diagnosed with mild COVID-19 disease

    Background. Pulmonary embolism (PE) is a known complication of COVID-19 disease. The mechanism of thromboembolic events appears to be stimulated by excessive thrombin production, inhibition of fibrinolysis and deposition of antiphospholipids and thrombi, as well as microvascular dysfunction in multiple vascular beds. The occurrence of PE has been well demonstrated in hospitalised patients with severe disease. Very few data are available on its incidence or prevalence in non-hospitalised patients diagnosed with a milder form of the disease.Objectives. To assess the prevalence of PE in non-hospitalised patients diagnosed with mild COVID-19 who presented with raised D-dimer levels and persistent or new-onset cardiopulmonary symptoms.Methods. This was a retrospective study conducted in the Department of Nuclear Medicine at Universitas Academic Hospital, Bloemfontein, South Africa. We reviewed the studies of 65 non-hospitalised patients with COVID-19 referred to the department from July 2020 to January 2021 for a perfusion-only single-photon emission computed tomography/computed tomography (SPECT/CT) study or a ventilation/perfusion (VQ) SPECT/CT study. All 65 patients had raised D-dimer levels with persistent, worsening or new-onset cardiopulmonary symptoms after the diagnosis of COVID-19.Results. Sixty-five patients were studied. The median (interquartile range) age was 46 (41 - 54) years and the majority (88.2%) were female. There were 22 patients (33.8%) with lung perfusion defects in keeping with PE. Two of these patients had a false-negative computed tomography pulmonary angiography (CTPA) study for PE performed the same day as their VQ SPECT/CT study.Conclusions. We confirm a high prevalence of PE in non-hospitalised patients diagnosed with mild COVID-19 who presented with raised D-dimer levels and persistent or new-onset cardiopulmonary symptoms. We recommend that irrespective of disease severity, hospitalised and non-hospitalised patients with COVID-19 presenting with persistent or new-onset cardiopulmonary symptoms and raised D-dimer levels should be investigated further for PE.

    Impact of Agricultural Credit on Economic Growth in Nigeria

    This study’s aim was to examine the influence of agricultural credit on Nigeria's economic growth for the period of 1981-2017. Data is sourced from Central Bank of Nigeria (CBN) statistical bulletin and world development indicator (WDI). The detailed objectives are to analyze the effect of the Agricultural credit guarantee scheme fund (ACGSF) and the deposit money bank credit to agric sector (DMBCA) on Nigeria's Economic Growth. Data was analyzed using the test for stationarity, Auto-Regressive Distributed Lag (ARDL). ARDL is adopted due to the mixed order of stationarity of the variables at levels and first difference. From the research results, it was established, in the long run, that DMBCA is significant and there exists a direct relationship, only in the short run, and the ACGSF is insignificant both the short and long run but has a direct relation in the short run and an inverse relationship in the long-run. Therefore, it is recommended, that the Federal Government should make coordinated attempts to ensure that farmers especially small-scale farmers have easy access to the financial aids and grants provided and the funds should be disbursed appropriately and adequately without any hitch

    Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

    Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
