Abstract: Background: Surgeries of adenoid, tonsils or both are common pediatric performed by otorhinolaryngologist, head, and neck surgeon worldwide. Clinical pattern and management varied in a different center. This study aimed at determining the rate, socio-demographic features, indications, barriers, types, complications and patients’ satisfaction with adenoid and tonsils surgery in low-income countries. Materials and Methods: This is a hospital-based retrospective study of pediatric patients who had adenotonsillectomy, adenoidectomy, and tonsillectomy in the study center. This study was carried out over a period of ten years from March 2007 to February 2017. Data for this study was obtained from the medical record department, ENT clinic operation booking register and theatre operation register. All the data obtained were statistically analyzed using SPSS version 16. The data were then expressed by descriptive statistics table, bar charts, and pie charts. Ethical clearance was sought for and obtained from the ethical committee of the institution. Results: A total of 463 patients were booked for adenoid and tonsillar surgery out of which 214 patients had surgery done during the study period. This represented 46.2% of the participants that had surgery done. Adenotonsillectomy peaked 38.3% at preschool age group: (1 - 5) years. There were 58.9% males and male to female ratio was 1.5:1. Majority 42.5% of the patients reside in the city while minority 25.7% of the patients were village dwellers. Preschool ages were the majority 40.2% while post-secondary schools ages were the minority 8.4% of the patients. The parents of the majority of the patients were 27.1% health workers and 24.8% business men, while the parent of the minority of the patients was 11.7% farmers and 16.4% industrial workers. Major indications for surgery were 52.3% obstructive sleep apnoea syndrome and 21.5% recurrent tonsillitis.

Journal of Mathematics , 2014, DOI: 10.1155/2014/458603
Abstract: Based on the works of Axtell et al., Anderson et al., and Ghanem on associate, domainlike, and presimplifiable rings, we introduce new hyperrings called associate, hyperdomainlike, and presimplifiable hyperrings. Some elementary properties of these new hyperrings and their relationships are presented. 1. Introduction The study of strongly associate rings began with Kaplansky in [1] and was further studied in [2–5]. Domainlike rings and their properties were presented by Axtell et al. in [6]. Presimplifiable rings were introduced by Bouvier in the series of papers [7–11] and were later studied in [2–4]. Further properties of associate and presimplifiable rings were recently presented by Ghanem in [12]. The theory of hyperstructures was introduced in 1934 by Marty [13] at the 8th Congress of Scandinavian Mathematicians. Introduction of the theory has caught the attention and interest of many mathematicians and the theory is now spreading like wild fire. The notion of canonical hypergroups was introduced by Mittas [14]. Some further contributions to the theory can be found in [15–19]. Hyperrings are essentially rings with approximately modified axioms. Hyperrings are of different types introduced by different researchers. Krasner [20] introduced a type of hyperring where + is a hyperoperation and is an ordinary binary operation. Such a hyperring is called a Krasner hyperring. Rota in [21] introduced a type of hyperring where + is an ordinary binary operation and is a hyperoperation. Such a hyperring is called a multiplicative hyperring. de Salvo [22] introduced and studied a type of hyperring where + and are hyperoperations. The most comprehensive reference for hyperrings is Davvaz and Leoreanu-Fotea’s book [18]. Some other references are [23–31]. In this paper, we present and study associate, hyperdomainlike, and presimplifiable hyperrings. The relationships between these new hyperrings are presented. 2. Preliminaries In this section, we will provide some definitions that will be used in the sequel. For full details about associate, domainlike, and presimplifiable rings, the reader should see [1, 4–6, 12]. Also, for details about hyperstructures and hyperrings, the reader should see [12]. Definition 1. Let be a commutative ring with unity. (1) is called an associate ring if whenever any two elements generate the same principal ideal of , there is a unit such that .(2) is called a domainlike ring if all zero divisors of are nilpotent.(3) is called a presimplifiable ring if, for any two elements with , we have or .(4) is called a superassociate ring if

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2014, DOI: 10.4236/ijohns.2014.34038

Objective: To determine the proportion of neonates with referral result on testing with transient evoked otoacoustic emission (TEOAE) and the associated risk factors. Method: Prospective evaluation of all neonates born in the Hospital within 6 months using the TEOAE. A hand-held Etymotic Research Otoacoustic Emission Scanner (Ero-scan Combo) was used with the child sleeping in the cot or the mother’s hand. Right and left ears were tested separately and the result was displayed automatically as “pass” when 100% of the in-built criteria were met and “refer” if otherwise. The subjects that passed in both ears were regarded as passes, while those with a refer in either the right/left ears or both ears were regarded as referrals and were thus subjected to rescreening in six weeks or on discharge from the special care baby unit. Analysis was done to find association between the outcome of TEOAE and the clinical and epidemiological risk factors. Result: TEOAE was carried out on 386 neonates, (194 males (50.3%) and 192 females (49.7%)). The mean age at screening was 2.3 days (SD = 1.5), the mean gestational age was 38.0 weeks (SD = 2.7) while the mean birth weight was 2.9 kg (SD = 0.7) and the mean Apgar score at 1 and 5 minute were 8.3 (SD = 1.0) and 9.8 (SD = 0.6). At the first step hearing screening, referral rate was 112 (29.0%); at the second stage, 31 (8.5%) neonates had referral in one or both ears. Fisher’s exact test showed that prematurity, multiple births, jaundice and small birth weight were significantly associated with a referral outcome. However, logistic regression revealed prematurity as a significant predictor of referral outcome with a negative predictive value of 12.61. Conclusion: The referral rate is high with prematurity as a significant predictor. This study calls for commencement of newborn hearing screening and strengthening of the public health measures in the developing countries.

African Research Review , 2007,
Abstract: This study investigated the relative effectiveness of cooperative and individualistic instructional strategies on students' problem solving abilities in secondary school chemistry. It made use of a 3 x 3 x 2 quasi-experimental, non-randomized factorial design. Two hundred and fifty (250) Senior Secondary two (SS II) chemistry students were purposively sampled from three public secondary schools in Ilesa Local Government Area of Osun State, Nigeria. Two research instruments: Researcher's Instructional Packages for solving Chemistry Problems (RIP) and Chemistry Performance Test (CPT) were developed, validated and used for the study. The reliability of the Chemistry Performance Test (CPT) was determined and found to be 0.62 using the Pearson Product Moment Correlation formula. Five hypotheses were raised and tested using Analysis of Covariance (ANCOVA). Two experimental groups (Cooperative Instructional group, Individualistic Instructional group) and a control group were used. The results of the analysis showed that there was a significant difference in the performance of chemistry students exposed to cooperative instructional Strategy, individualistic instructional strategy and conventional teaching method. Both the cooperative instructional strategy and individualistic instructional strategy improved the performance of the learners. The cooperative instructional strategy was found to be most effective in enhancing better performance of the learners. African Research Review Vol. 1 (1) 2007: pp. 121-130

Open Journal of Forestry (OJF) , 2015, DOI: 10.4236/ojf.2015.54038
Abstract: Elm bark beetle Scolytus kashmirensis is a key pest of elm nurseries in the social forestry ecosystem of Kashmir. The biological and morphological characters of this species were determined both in field and in the laboratory. The larvae remained inactive throughout the winter which resumed their activity from the third week of March. Pupation started from the first week of April and the first swarming adults appeared from the last week of April. After emergence, the adults fly to suitable trees and undergo maturation feeding for 8.4 (±0.68 SD) days and females laid 46 (±9.45 SD) eggs on an average. The eggs hatched after an incubation period of 11 - 13 days. The five larval instars were distinguished from each other on the basis of the width of head capsule measurements. The larvae completed their development in 40 - 46 days. The pupal stage lasted for 10 - 20 days and finally adults emerge that lived for 45 - 60 days. The single longitudinal maternal gallery measured 42.67 (±11.07 SD) mm (on average) long and the larval gallery was 43 (±10.96 SD) mm (on average) in length. The seasonal distribution of various life stages and the number of generations were also recorded.

The relationship between Nigerian Bonny Light crude oil (NBLCO) induced hypoglycaemia and endogenous serum insulin concentration; the role of antioxidant vitamin C or E supplementation was the focus of this study. Forty adult male Wistar rats were randomly divided into group I, which served as the control, group II, which was oral gavaged 6 ml/kg of NBLCO, groups III and IV, which were in addition to 6 ml/kg of NBLCO supplemented with 9 ml/kg and 1 mg/kg of vitamin E or C, respectively for 28 days. Results showed that NBLCO significantly (p < 0.05) lower body weight and food intake compared with control. These effects exerted by NBLCO were however significantly (p < 0.05) reversed by vitamin E or C supplementation. The NBLCO significantly (p < 0.05) reduced fasting blood glucose (FBG) when compared with control, the antioxidant vitamins supplementation significantly (p < 0.05) reversed the crude oil effect. The mean serum insulin level in NBLCO, vitamin E or C supplemented groups is not significantly different from the control. There was no significant correlation between FBG and fasting serum insulin concentrations in all the groups on day 28. It has been demonstrated in this study that direct oral ingestion of crude oil (NBLCO) could reduce food intake, body weight and cause hypoglycemia; the hypoglycemia may not be a function of serum insulin concentration. Interestingly, the hazardous effects of NBLCO could be ameliorated with antioxidant vitamin C or E supplementation.

Journal of Electronics Cooling and Thermal Control (JECTC) , 2011, DOI: 10.4236/jectc.2011.11001
Abstract: Heat transfer to pins swimming in non-isothermal fluidic systems is theoretically analyzed. Four different cases are considered: [A] pins aligned longitudinally in flowing fluid having constant temperature gradient, [B] pins aligned transversely in flowing fluid flow with constant temperature gradient, [C] pins moving longitudinally towards a heated surface, and [D] pins moving transversely towards the heated surface. The Appropriate unsteady energy transport equations are solved and closed form solutions for the fin temperatures are obtained. Accordingly, different performance indicators are calculated. It is found that heat transfer to the swimming fin increases as the fin thermal length, Peclet number and fluid temperature difference along the fin length increase. It decreases as fluid temperature index along the motion direction increases. Moreover, the swimming pins of case C are found to produce the maximum system effective thermal conductivity. In addition, pins of case B with thermal lengths above 11 produce system thermal conductivity independent on the thermal length. Meanwhile, pins of case A having thermal lengths above 10 produce system thermal conductivities less responsive to the thermal length. The system thermal conductivity is noticed to increase as the thermal length and Peclet number increase. Eventually, pins of case D produce system thermal conductivities that are independent on the transverse temperature. Finally, the results of this work provide a basis for modeling super convective fluidic systems that can be used in cooling of electronic components.

Journal of Electronics Cooling and Thermal Control (JECTC) , 2015, DOI: 10.4236/jectc.2015.53004
Abstract: Laminar flow and heat transfer in different protruding-edged plate systems are modelled and analyzed in the present work. These include the Parallel Flow (PF) and the Counter Flow (CF) protruding-edgedplate exchangers as well as those systems being subjected to Constant Wall Temperature (CWT) and Uniform Heat Flux (UHF) conditions. These systems are subjected to normal free stream having both power-law velocity profile and same average velocity. The continuity, momentum and energy equations are transformed to either similarity or nonsimilar equations and then solved by using well validated finite difference methods. Accurate correlations for various flow and heat transfer parameters are obtained. It is found that there are specific power-law indices that maximize the heat transfer in both PF and CF systems. The maximum reported enhancement ratios are 1.075 and 1.109 for the PF and CF systems, respectively, at Pr = 100. These ratios are 1.076 and 1.023 for CWT and UHF conditions, respectively, at Pr = 128. Per same friction force, the CF system is preferable over the PF system only when the power-law indices are smaller than zero. Finally, this work demonstrates that by appropriately distributing the free stream velocity, the heat transfer from a plate can be increased up to 10% fold.

International Journal of Biological and Medical Research , 2011,
Abstract: A total of 882 individuals comprised of 794 (90.03%) females and 88 (9.97%) males were examined in Osogbo, Osun State, Nigeria between January 2005 and March 2006 from various centres for Trichomoniasis. Ninety one (10.3%) and 106 (12.02%) prevalence of Trichomonas vaginalis were reported with the wet mounts direct microscopy and modified oxoid culture medium method respectively. However, there was no statistically significant difference in prevalence (P>0.05). Infection rates were significantly higher (P<0.05) in females than in males and in the age group 21 – 30 years. Infection rate was also significantly higher among female students and non pregnant females on contraceptives than other groups. The clinical symptom of vaginal discharge (VD) recorded the highest prevalence (52.83%) which was statistically significant compared to other clinical signs in the study. The control of the disease condition was highlighted.
