The NHIS provides free or highly subsidized healthcare to all people by providing financial fortification. However, the financial sustainability of the scheme is threatened by numerous factors. Therefore, this work sought to provide a solution to process claims intelligently. The provided Petri net model demonstrated successful data flow among the various participant. For efficiency, scalability, and performance two main subsystems were modelled and integrated - data input and claims processing subsystems. We provided smart claims processing algorithm that has a simple and efficient error detection method. The complexity of the main algorithm is good but that of the error detection is excellent when compared to literature. Performance indicates that the model output is reachable from input and the token delivery rate is promising.

Cnidoscolus aconitifolius contains various phenolic compounds possessing anti-inflammatory and antioxidant properties. This study aimed to evaluate the protective effect of the Methanol Extract of Cnidoscolus aconitifolius (MECA) against LPS-induced memory impairment, oxidative stress and neuroinflammation in rats. Thirty male Wistar rats were divided into 5 groups (n = 6). Group 1 served as the control and received the vehicle, group 2 was negative control, groups 3–5 received MECA (25, 50, and 100 mg/kg) for 14 days. Groups 2–5 were daily injected with LPS (250 μg/kg, i.p) from day 8–14 of treatment. Memory impairment was evaluated after the last LPS administration using the Y-Maze Test (YMT) and Novel Object Recognition Test (NORT). Brain prefrontal cortex (PFC) and hippocampus (HPC) sections were obtained and levels of reduced glutathione (GSH), malondialdehyde, catalase, nitrite, acetylcholinesterase, and TNF-α and IL-6 were determined. Oral administration of MECA significantly reversed LPS-induced memory impairment in the YMT and NORT. MECA significantly reduced LPS-induced elevated malondialdehyde and nitrite, while preventing depletion of GSH and catalase in the PFC and HPC sections of the brain. Acetylcholinesterase activity is also reduced. MECA (100 mg/kg) significantly reduced IL-6 and TNF-α levels in PFC and HPC of LPS-treated rats. This study showed that the methanol extract of Cnidoscolus aconitifolius has significant protective effect against lipopolysaccharide-induced memory impairment via mechanisms related to inhibition of neuroinflammation and oxidative stress.

This study characterize, classify and evaluates the function of topography on spatial variability of some selected soil properties to assist in designing land management that support uniform agricultural production. The study site, an agricultural land, was part of the derived savanna zone in southwest Nigeria. Four soil profile pits each were established along two delineated toposequence and described following the FAO/UNESCO guidelines. Samples were collected from the identified genetic horizons. Properties of four soil series developed on different positions of the two delineated Toposequence viz upper, middle, lower slopes and valley bottom positions respectively were studied. The soil samples were analysed for selected physical and chemical properties and data generated were subjected to descriptive and inferential statistics. The results showed that soil colour, depth and texture varied in response to changes in slope position and drainage condition. The sand content ranged from 61 to 90% while the bulk density ranged between 1.06 g cm-3 to 1.68 g cm-3. The soils were neutral to very strongly acid with low total exchangeable bases. Available phosphorus value were low while the extractable micronutrient concentration varied from low to medium. Soils of Asejire and Iwo series mapped in the study area were classified as Typic isohyperthermic paleustult, Apomu series as Plinthic isohyperthermic paleustult and Jago series as Aquic psamment (USDA Soil Taxonomy). These soils were correlated as Lixisol, Plinthic Lixisol and Fluvisol (World Reference Based), respectively. Major agronomic constraints of the soils associations mapped in the study area were nutrient availability, nutrient retention, slope, drainage, texture, high bulk density and shallow depth. The study concluded that the soils were not homogenous, shows moderate spatial variation across the slope, had varying potentials for sustainable agricultural practices, and thus, the agronomic constraints should be carefully addressed and managed for precision agriculture.

The 3 MeV proton irradiation effects on SiGe low noise amplifier (LNA) (NXP BGU7005) performanceunder different voltage supply VCC (0 V, 2.5 V) conditions were firstly experimental studied in thispresent work. The S parameters including S11, S22, S21, 1 dB compression point and noise figure (NF) of thetest samples under different bias voltage supply were measured and compared before and after 3 MeVproton irradiation. The total proton irradiation fluence was 1 1015 protons/cm2. The maximumdegradation quantities of the gain S21 and NF of the test samples under zero bias are measuredrespectively 1.6 dB and 1.2 dB. Compared with the samples under 2.5 V bias supply, the maximumdegradation of S21 and NF are respectively 1.1 dB and 0.8 dB in the whole frequency band. It is noteworthy that the gain and NF of SiGe LNAs under zero-bias mode suffer enhanced degradation comparedwith those under normal bias supply. The key influence factors are discussed based on the correlation ofthe SiGe device and the LNA circuit. Different process of the ionization damage and displacement damageunder zero-bias and 2.5 V bias voltage supply contributed to the degradation difference. The underlyingphysical mechanisms are analyzed and investigated

Genetic diversity and relationship of Nigerian Muscovy duck populations

Muscovy duck (Caraina Moschata) is an economically important species due its unique meat taste and low-caloric content. It is one of the domestic poultry species in Nigeria as it ensures food security to the rural sectors. Rearing of Muscovy is concentrated in some part of the country due to its peculiar nature as water loving poultry species and peoples belief. In this study, we analyzed the genetic diversity and relationship of Muscovy duck populations collected from 15 different locations where Muscovy duck lovers resides in four states (Kaduna, Kwara, Niger and Oyo) of Nigeria based on mtDNA DNA Cytochrome P450 Family 2 Subfamily U Member 1 (CYP2U1) gene. A total of 48 polymorphic sites consisting of substitutions with 33 singletons variables was observed. The 82 sequences were assigned into 32 distinct haplotypes. Haplotype diversity was 0.7925. The Phylogenetic analysis showed close clustering across all locations with the exception of BART 495, PAT 35 and KEY 764 individuals. The maternal genetic structure likely suggests the extensive genetic intermixing within the country. In addition, the differentiation of BART 495, PAT 35 and KEY 764 may be due to a certain demographic history and/or artificial selection that shaped its haplotype profile. The current data on Nigerian Muscovy duck genetic diversity based on nuclear DNA CYP2U1 gene do not permit us to make further conclusions; therefore, more research evidence from genetics and archaeology is still required.
