An Analysis of Political Implications in Animal Farm from the Perspective of New Historicism
Authors: Xiao Shilin 
Published: March 2022

George Orwell is a famous writer in the 20th century in England, especially known for his humanitarian spirit. Among his sharply written works, Animal Farm is of significant value to focus our attention on. This political allegory successfully creates a set of animal images, with some certain hidden meaning of political life. New Historicism offers readers another perspective to reorient into the context behind the text itself and reconsider the intertextuality between history and texts. Montrose proposes two concepts, “textuality of history” and “historicity of texts.” In the light of the two key concepts, this paper aims to take a descriptive approach to the political implications in Animal Farm with a focus on the close relationship between history and texts.

The body during normal metabolic function produces free radicals which are highly reactive species. Free radicals could also be introduced into the body from the environment. The oxidation induced by reactive oxygen species can result in DNA mutation, membrane protein damage and cell membrane disintegration. The present study assayed the preliminary phytochemicals, total phenolics and total flavonoids and free radicals scavenging ability of methanol extract of Jatropha tanjorensis leaf. Standard methods for determining phytochemicals, reducing power, nitric oxide scavenging, hydroxyl radical, and lipid peroxidation scavenging activity were employed. The phytochemical screening result revealed the presences of phenols, flavonoids, saponin, alkaloids, tannins, terpernoids and steroids. The total phenolic content of methanol extract of Jatropha tanjorensis leaf measured by Folin-Ciocalteau reagent in terms of gallic acid equivalent was 11.35±0.82mgGAE/g. The flavonoid content of the plant sample calculated as Quercetin equivalent was 15.91±1.60mgQCE/g. GC-MS results revealed relevant pharmacological bioactive compounds. The antioxidative activity of the plant’s extract correlated with total phenolic content. The radical scavenging activity showed a dose dependent increase in the reducing power. The minimum NO inhibitory activity was 8.88±0.63 at 200µg/ml and the maximum activity was 32.70±2.71 at 800µg/ml. The minimum percentage H2O2 radical inhibitory activity was 8.30±0.88 at 200µg/ml and a maximum activity was 22.80±2.28 at 800µg/ml. There was also an increase scavenging effect of lipid peroxide radical in concentration dependent manner. The results of this study indicate that the leaf of Jatropha tanjorensis possess antioxidant properties and could serve as free radical inhibitor

Authors: Ibrahim Ado , Na'aliya J. , Haleelu M. M. , Sani Salihu 
Published: March 2022

Schiff base derived from condensation of 2-hydroxy-1-naphthaldehyde and 4-iodoaniline was synthesized and used for the preparation of Co(II) and Ni(II) complexes. The complexes were characterized by IR, Powder-XRD, Solubility test, thermal analysis, conductivity measurement, magnetic susceptibility and elemental micro analysis. IR study indicated a strong band in the spectra of the Schiff base at 1603 cm-1 assigned to azomethine v(C=N) stretching vibration. It shifted to new frequency regions (1618 - 1622 cm-1) in the spectra of the complexes indicating the formation of the desired complexes. The decomposition temperatures of the complexes are in the range of (260-265) oC , molar conductance values are in the range of (4.51 -11.31) Ohm-1cm2 mol-1, indicating non electrolytic nature of the synthesized complexes in DMF. Magnetic susceptibility measurement indicated that Co(II) and Ni(II) complexes are paramagnetic and exhibit magnetic moment in the range of 2.92-3.24 BM, the values correspond to the square planar geometry. The Powder x-ray diffraction analysis showed the patterns of the metal(II) complexes were different from the reactants, signifying that reactants were changed to product. The CHN analysis results show the formation of 1:2 metal to ligand ratio. The synthesized compounds have been studied for antimicrobial activity using pathogenic bacteria and fungal pathogens by disc diffusion method. The results indicated that metal complexes (10 – 15 mm inhibition zone) are more active compared to Schiff base (8 – 12 mm inhibition zone) against the test organisms.
COMPARATIVE EXTRACTION OF Mn AND Pb USING EDTA AND CITRATE TO ASSESS THEIR MOBILITY FROM TWO DUMP SITES IN ZARIA METROPOLIS
Authors: Samuel-Okey Comfort , Ajibola V. O. 
Published: March 2022

An estimate of the labile fractions of different trace metals (Mn and Pb) in soil from two dumpsites with complexing agents (EDTA and Citrate) was carried out. The dump sites used for this study receives both commercial and domestic wastes. Physiochemical parameters and the total metal concentrations of the soil was determined, extraction with EDTA and Citrate were used to study the potential metal extraction capacity at different time intervals and the extraction rates of metal released as a function of time (between 0 to 24 hr). The relatively low levels of silt, clay, organic matter and CEC indicates high permeability, hence leachability of heavy metals in the soil and suggest that it might be amenable to remediation by soil washing. The removal efficiency showed that complete solubilization of metals did not occur, as not all the complexing agents added to the soil, was bound to the target metal. This might be due to the presence of other ions such as Ca and Fe which form relatively high stable complexes. EDTA yielded much more than citrate for both metals under consideration. Lead was extracted more than Manganese, which suggest Lead has been more labile in solution than Manganese and EDTA as a stronger complexing agent than citrate. The level of extraction was constant for the period of 60 min to 720 min after which it increased considerably.

Before a wind energy system is installed, modelling and prediction of wind speed plays an important role during wind energy planning stage. The short term wind speed of Katsina was measured at 5 m elevation at different locations using hand held digital rotating cup. In order to obtain long term wind speed, a prediction model using artificial neural network (ANN) was developed. The model was implemented using Matlab/Simulink 2019, which consists of 3 layers with back propagation algorithm. The model has 5 inputs which were selected using trial and error techniques. The model was trained, tested and validated using available 1 year data obtained from Katsina state agricultural and rural development agency KATARDA in 34 ground stations situated in each local government. After, the development of the ANN wind speed prediction model, the best architecture has root mean square error (RMSE) of 8.9%, mean biased error (MBE) 4.3% while the optimum correlation value of 0.9380 was realized. The predicted annual wind speeds are in the range of 0.9-13.1 m/s and the yearly evaluated wind speed are 3.2, 2.6 and 4.7 m/s for Katsina central, Katsina south and Katsina north respectively. The wind speed map of the study area was developed; the map shows the locations wind high, moderate and low wind energy potential. The map will serve as a reference for wind energy development in the state and will provide the policy makers and potential investors as a blue print for wind energy development.

Cabbage and lettuce were collected from three locations each along the irrigation farms of Rivers Jakara and Getsi. Domestic and industrial waste are freely discharge into these rivers. Thirty Nine Albino Rats were divided into Thirteen (13) groups where Animals in groups 1-12 were fed with diet containing 10% cabbage or lettuce. The 13th group were fed with normal diet. After 90 days, the Animals were sacrificed, blood and organs were collected. Fe had the highest level in the blood and significantly different from the control in all the groups. The level of other essential heavy metals is in the following order of decreasing concentration, Fe> Zn > Cu > Cr > Mn > Co while Pb has the highest concentration and in the following order of decreasing concentration Pb > As > Cd > Ni > Hg. A significant decrease in weight of the heart, kidney and pancreas was observed and a significance difference in the organ/body weight coefficient was observed in the Liver (group 3, 4 and 11) Kidney (group 5, 6 and 7) and Pancreas (group 1, 3 and 9). The bioaccumulation index (BAI) shows that eight (8), Seven (7) and Six (6) of the elements analyzed accumulates in the Liver and the Pancreas, Kidney and Heart respectively. Liver accumulated more Cadmium, Lead and Nickel while Pancreas accumulated Nickel, Manganese and Cobalt. Consumption of these vegetables led to reduction in organ weight, increase blood levels and bioaccumulation of some heavy metals in vital organs of albino rats

Published: March 2022

The demand for data in the 4G (Fourth Generation networks) and 5G (Fifth Generation networks) is becoming excessively high and the solution is being investigated to effectively utilize the available spectrum at the physical layer across different protocols to speed-up access from 2.5 to 10 times. Furthermore, the current proposals for 5G systems is envisaged to increase spectrum efficiency which brings about customer satisfaction, network density and operational efficiency, using newly 3.5 GHz NCC auctioned spectrum bands. The CPU processing power and cloud computing are expected to be the key driving factors in the evolution of wireless Network from 1G to 5G. These support wide range of new technologies like IoT, smart cities and Cyber and information Security as well as broadband penetration using entirely new Network architectural concept as a total transformation. This paper presents 5G network tariff implementation strategies and proposes a model of revenue generation which would enable a market mechanism that would allow the customer to communicate with the 5G Network and negotiate a contract based on some QoS (Quality of Service) parameters like blocking probabilities of High Priority Users (HPUs) and Low Priority Users (LPUs) , delay, and price. The percentage Improvement in Cumulative Revenue (CR) generated by the proposed model over the existing models is 10. Recommendations were made on the way forward for the optimum 5G tariffs in the Nigerian context
