Coordinated attacks on some villages and communities in Katsina State had rendered thousands of people homeless while some infants became orphans. The study was carried out in some designated Internally Displaced Camps in the seven most affected Local Government Areas in Katsina State. The researchers explored three qualitative data collection techniques in the study and elicited data from the field. Key Informant Interviews were conducted with camp officials, In-Depth Interviews were conducted with parents of the children aged 0-8 years taking refuge in the camps, and a non-participant observation method was used to observe the behaviour of the targeted children. The study revealed that children uprooted from their various villages were in dire need of assistance, particularly food, shelter, and medical attention. Also, there was no provision for temporary early childh...

These changes, including chromosomal inversions and overexpression and/or changes in allele frequencies of thermotolerance-associated genes, may facilitate insecticide resistance through pleiotropy. This study investigated the impact of thermotolerance on pyrethroid resistance in four populations of the malaria vector An. gambiae s.l., from the savanna/sub-Sahel of northern Nigeria. Anopheles coluzzii and An. gambiae s.s. were the only malaria vectors found, sympatric in all the sites, with the former species predominant. High thermotolerance was observed, with no mortality at 38 °C, and LT50 of ~44 °C. Significantly high permethrin resistance was observed (mortality < 50%) in 44 °C heat-hardened (exposure to an intermediately high temperature provides protection to a more severe temperature or insecticide)...

Hopfield neural network (HNN) is one of the major type artificial neural network (NN) popularly known for it used in solving various optimization and decision problems based on its energy minimization machinism. The existing models that incorporate standalone network projected non-versatile framework as fundamental Hopfield type of neural network (HNN) employs random search in its training stages and sometimes get trapped at local optimal solution. In this study, Ants Colony Optimzation Algorithm (ACO) as a novel variant of probabilistic metaheuristic algorithm (MA) inspired by the behavior of real Ants, has been incorporated in the training phase of Hopfield types of the neural network (HNN) to accelerate the training process for Random Boolean kSatisfiability reverse analysis (RANk...

To facilitate evidence-based resistance management, antimalarial resistance mutations were investigated in Plasmodium falciparum multidrug resistance-1 (pfmdr1) and chloroquine resistance transporter (pfcrt), in isolates from Kano, northwestern Nigeria. Out of the 88 samples genotyped for pfmdr1 N86Y mutation using PCR/restriction fragment length polymorphism, one sample contained the 86Y mutation (86Yfrequency = 1.14%). The analysis of 610 bp fragments of pfmdr1 from 16 isolates revealed two polymorphic sites and low haplotype diversity (Hd = 0.492), with only 86 Y mutations in one isolate, and 184 F replacements in five isolates (184Ffrequency = 31.25%). The analysis of 267 bp fragments of pfcrt isola...

The methodological issues are based on documentary and content analyses and adopt a sociological approach as the framework of analysis. The approach argues that a federal structure permeated by forces of globalization, primordial sentiments and pretensions, agitations for self-determination are presented as separatist or secessionist movements. Research finding argues that the onset of globalization in Third World nations was perpetuated through colonial domination which created a divide and rule policy in the federal state of Nigeria. The policy of domination and marginalization by European colonialist and continued by the first republic politicians and military dictators have triggered agitations and counter agitations for secessionism in Nigeria. It is also argued from the research finding that deregulation of the downstream se...

In this study, the resistance profile and its possible mechanisms was characterised in a field population of the major malaria vector Anopheles coluzzii from Port Harcourt, the capital of Rivers state, in the Niger-Delta Region of Nigeria. Larvae collected in Port-Harcourt, were reared to adulthood and used for WHO bioassays. The population exhibited high resistance to permethrin, deltamethrin and DDT with mortalities of 6.7% ± 2.4, 37.5% ± 3.2 and 6.3% ± 4.1, respectively, but were fully susceptible to bendiocarb and malathion. Synergist bioassays with piperonylbutoxide (PBO) partially recovered susceptibility, with mortalities increasing to 53% ± 4, indicating probable role of CYP450s in permethrin resistance (χ2 = 29.48, P < 0.0001). Transcriptional profiling revealed five major resistance-associated genes overexpressed in the field samples comp...

To achieve effective control of the pandemic, efforts need to be holistic and global. Understanding patients’ demographics and clinical characteristics will assist in the control of the infection. However, there is a paucity of studies on the clinical presentation of COVID-19 patients from Nigeria and indeed Africa. Thus, this retrospective case series evaluated the medical records of COVID-19 patients admitted in a tertiary hospital in Nigeria. Patients’ demographics, and other clinical variables were assessed and presented. Data of 14 patients with complete records were included in the study. Most of the patients (78.6%) were males and the mean age of the study participants is 63.5 years (SD; 11.5). The commonest presenting symptoms were fever (93%), cough (71.4%), and dyspnoea (57.1%). At presentation, 13 patients had coexisting diseases while 8 (57.0%) patients had ...

However, alkaline transesterification of these oils makes the process challenging due to the presence of large amount of free fatty acids (FFA), which forms soap on reaction with alkali. Hence, it is necessary to reduce FFA present so that alkaline catalyzed transesterification can be carried out. In this work, biodiesel fuel was produced using diphenylamine functionalized magnetic mesoporous silica SBA-15 as catalyst for the esterification of free fatty acid (FFA) present in neem oil (NO) and its effect on esterification reaction was studied. Optimum catalyzed esterification was achieved using 1 g diphenylamine functionalized magnetic mesoporous silica SBA-15 as a solid base catalyst with a methanol to oil ratio of 9:1, at 60°C and reaction time of 1.25 h. During this process, FFA was converted into fatty acid methyl esters. The acid value of NO oil was reduced to 7.34 mg KOH/g from 52.45 mg KOH/g, accounting for 86% conversi...

It asserts the nature of effluent released into the water body and also the impact of effluent on water quality. However the important water quality became relatively slowly as early human could only judge water quality through the physical senses of sight, taste and smell, now a days there is an increase of contamination of natural water bodies by industrial effluents in developing and densely populated countries like Nigeria, because rivers are major means of waste disposal and especially effluents from industries nearby. The data used in this research were generated from direct field measurement of pH, Conductivity, and Turbidity, heavy metal profiles (Chromium & Nickel) from Kaduna Refinery Effluent. The mean concentrations of the metals; chromium, iron, nickel, and zinc with the standard ...

He was extricated by coworkers after ten minutes. Upon EMS arrival, he was unconscious with decerebrate posturing and fixed, dilated pupils. He had multiple contusions. The patient was normotensive but tachycardic. Due to his altered mental status and suspected crush injuries, he underwent field drug assisted intubation with ketamine and succinylcholine. He received a saline bolus while en-route to the trauma center. The ED continued providing supportive care. CT scans revealed left rib fractures, an occult left pneumothorax, and a fracture of the left ulnar styloid process (Figs. 2 and 3). 1 He was admitted to the Trauma ICU, but he made an unexpectedly rapid recovery, being discharged 36 h later at his baseline with only PCP follow-up.

A multi-delay case is considered and a new approach to determine the roots of the eigenvalues is obtained. The extension to include multiple lags is an improvement on the already existing ones that are at most two or less. It is found that the new extended results can be used to obtain series expansion for the determination of roots of the characteristics equations under consideration.

It is however; found that certain restrictions are placed hence making it impossible to use the existing criteria to solve problems for second order equations. A new set of oscillatory criteria is established to generalize all forms of solutions to second order linear ordinary differential equations using integral technique. It is also discovered that certain existing restrictions are removed. It is also found that the solutions to the second order ordinary differential equations are oscillatory under the new set of conditions. An example is constructed to test the applicability of the set conditions.

The structural morphology and functional groups present were investigated using scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Various sorption parameters such as effect of pH, contact time, initial dye concentration and adsorbent dosage were studied. The percentage removal of methylene blue increased with decrease in initial methylene blue concentration and increased with increase in contact time and dose of the adsorbent. Equilibrium data were analysed using Langmuir and Freundlich isotherm models. Kinetic data were studied using pseudo-first order and pseudo-second order kinetic models.
