This was to set the basis for deploying a multi-frequency GPR system for the non-invasive monitoring of rootmass development and evaluation of plant development and health. The survey involved a single GPR Transect with a total length of 60.1 m established along the middle of a line of matured Teak trees. Data was collected at 250 MHz, 500 MHz and 1000 MHz, simultaneously using a wheel-triggered Utsi Trivue system. Data processing involved a dewow, static corrections, gain application and background removal. A root zone consisting of two layers was delineated and a total of 159 hyperbolae were interpreted as roots. The roots were limited to the shallow subsurface, the upper 1.1 m of a potential root zone 1.6 m deep. Imaged roots generally occur in clusters that create much disturbance of the otherwise continuous reflections in the root zone. Often, roots may be laterally offset from the location of tree bases on the Transect. We further identified a potential set of laterally migrating roots in a zone of undisturbed ground outside the main groove indicating the lateral reach of the usually shallow roots of the Teak tree. The results set the basis for further work in root-mass estimation and monitoring tree health within our team.

This research was aimed to carry out the antioxidant activities guided isolation and characterization of phytocompounds from C. senegalensis methanol crude extract. The plant sample was extracted using maceration and concentrated on a rotary evaporator at 45oC. Three different but complementary methods; Ferric reducing antioxidant power (FRAP), Nitric oxide and hydrogen peroxide assays were used to evaluate the antioxidant activities of C. senegalensis crude extracts. Column chromatography was used to isolate and purify the compounds from the most active n-hexane fraction and coded as CSC-1, CSC-2 and CSC-3. The compounds were characterized using NMR (1H & 13C), GC-MS, melting point determination and in comparison with literature. The percentage free radical scavenging activity for FRAP, nitric oxide and hydrogen peroxide assays were 94.51%, 92.38% and 91.67% respectively while that of ascorbic acid standard was 95.43±0.76%. The isolated compounds were identified as 1- hexacosanol (CSC-1), 1-triacontanol (CSC-2) and oleic acid (CSC-3).

Results revealed that all the samples had total viable bacterial counts, fungal counts and coliform counts which ranged from 61.25 to 85.32 CFU/100 mL, 10.00 to 35.32 SFU/100 mL and 6 – 24 MPN/100 mL respectively, which were higher than the set WHO limit.

Raw BAFM fruit was processed by soaking for 24 hours, dried and incorporated in the diets at 0.00, 2.50, 5.00 and 7.50% in T1, T2, T3 and T4 respectively. Acidifier (Fysal®) was supplemented in the diets of T2-T4 at 0.1%. The study monitored the following parameters; initial weight, final weight, weight gain, feed efficiency, and mortality rate. Cost benefit was also determined at the end of the study. Results obtained indicate that growth performance was poorer in chickens fed the control diet compared to others. Starter-phase chicks fed diets with the highest BAFM dietary inclusion level (7.5%) exhibited enhanced weight gain, improved feed conversion efficiency, and reduced feed cost per unit weight gain, while the pooled performance showed that the parameters declined at 7.5%. Cost benefit showed that feed cost per kilogram gain reduced up to 5% inclusion level of BAFM in the diets while it slightly increased at 7.5%, though better than the control group. At 5% dietary inclusion of BAFM with acidifier supplementation, feed cost per kilogram gain reduced by ₦95.22 (18.49%).

When developing a wireless network's data transmission routing system, energy consumption is among the most essential components. Designing an energy-efficient (WSN) routing framework is challenging. Several energyefficient routing algorithms exist for effectively transferring data packets between cluster members (CM) and cluster heads (CH). Some suggest the change of state of the nodes that made up the network from active to sleep in the event where the nodes are not sensing of sending data as a method of energy optimisation while others reduce the distance between the nodes because the distance between nodes is directly proportional to the amount of energy use during data transmission. Whatever the method may be, achieving reduced energy consumption in a WSN environment is an enormous task due to the need for both long network life and network efficiency. This paper reviews some research and energy saving techniques that had been carried out on WSN over a period of time.

The Kirby-Bauer disc diffusion method was used to assess antibiotic susceptibility on all the isolates, and the double disc synergy test was used to validate extended spectrum beta-lactamase (ESBL) production phenotypically. The PCR techniques were used to detect β-lactamase genes. The sample distribution of the forty clinical isolates were collected from the work benches and the distribution was: urine (17), blood (9), wound (6), sputum (4), amniotic fluid (3) and tracheal aspirate (1). Klebsiella pneumoniae was the most prevalent organism with 17 isolates ( 42.5% ).
