Hydrologic Modeling of Landscape Functions of Wetlands
An extensive literature review of existing hydrologic and hydraulic models has been conducted to select a mathematical model suitable for simulating the dynamic processes of wetlands and their impact on the hydrologic responses of the watershed containing the wetlands. Due to the lack of a single suitable model, a base model was developed by incorporating watershed and channel-routing components from two of the reviewed models. This physically based, distributed-parameter model has been tested and applied to one of the selected test watersheds in Illinois to evaluate the impact of wetlands on the watershed hydrology. The simulation results indicate that the peakflow reduction due to the presence of wetlands is significant for wetland areas of up to 60 percent of the watershed area. The reduction in peakflow was observed to diminish with distance downstream of the wetland outlet, indicating that the influence of the wetlands decreases as the distance from the wetland increases. The model results cannot be generalized for other watersheds until the model has been tested and verified for several watersheds in different parts of Illinois.Ope

Phytochemical, Antimicrobial and Bio-Active Component Analysis of Platycerium Superbum (L.) Methanolic Extract
Plants have been considered for several years to be a valuable source of compounds that can be active against the activity of many pathogenic organisms but lower plants are rarely considered useful in many cases. In this study, the phytochemical analysis, antimicrobial activity and Gas Chromatography-Mass Spectrometer (GC-MS) analysis was carried out on P. superbum methanolic extract following standard procedures from earlier reports. The qualitative phytochemical screening result revealed the presence of important phytochemicals like tannin, saponin, alkaloid, flavonoid, protein, terpenoid, oxalate, glycoside, anthraquinone, and phytobiotin in the plant extract. Flavonoid has the highest quantity of 6.69mg/g while terpenoid has the lowest quantity of 0.66mg/g. The result of the antimicrobial activity of P. superbum revealed that the plant extract compared with some standard drugs like Ciprofloxacin, Streptomycin, Septrin and Gentamycin had significantly the same level of activity at certain concentrations while the extract showed greater potency against the test microbes at some other concentrations.The GC-MS analysis of the extract revealed the presence of essential bioactive compounds like Silanediol, Cyclohexanecarboxylic acid, Methyl ester, Cyclohexacarboxylic acid, Bicyclo [3.1.1] Heptane, Bicyclo [5.2.0] nonane, Methyl palmitate and 7– Octaecenoic which have been reportedly given some therapeutic and industrial credits
Watershed Monitoring and Land Use Evaluation for the Lake Decatur Watershed
Lake Decatur is the water supply reservoir for the city of Decatur. The reservoir was created in 1922 by construction of a dam to impound the flow of the Sangamon River. The dam created a lake with a volume of 20,000 acre-feet, but was later modified in 1956 to increase the maximum capacity of the lake to 28,000 acre-feet. The drainage area of the Sangamon River upstream of Lake Decatur is 925 square miles.published or submitted for publicationis peer reviewe
MALARIA PARASITAEMIA AMONG BLOOD DONORS IN ILORIN, NIGERIA.
Background: The prevalence of malaria parasitaemia among blood donors in Ilorin has not been documented. In this study, we determined the prevalence of malaria parasitaemia among blood donors in Ilorin, as well as, the sociodemographic and other factors associated with it.
Method: This was a hospital- based cross sectional study involving 308 consenting blood donors. The sociodemographic characteristics of participants as well as blood donation history were obtained using structured questionnaires specifically designed for this purpose. Giemsa-stained thick and thin blood films to identify malaria parasites were performed using standard method. ABO blood grouping and haemoglobin electrophoresis tests were also done using standard methods.
Results: The prevalence of malaria parasitaemia among blood donors in Ilorin was 27.3%. The parasite species found were more of Plasmodium falciparum(85.7%) than Plasmodium malariae(14.3%) . There was no age or sex difference in malaria parasitaemia. (p-value of 0.8 and 0.32 respectively). A greater proportion of blood group O individuals had malaria parasitaemia than groups A and B but this difference was not significant (p-value = 0.13). There was also no significant difference among haemoglobin genotypes.
Conclusion: The prevalence of malaria parasites among blood donors in Ilorin is considerably high and lack of routine screening of blood puts recipients at risk. We recommend that routine screening for malaria parasites be commenced in our blood banks. Treatment of donor blood with riboflavin and UV light to inactivate malaria parasites and other infectious pathogens before they are transfused to patients may also be considered in our blood banks
