Abstract:Let \(G = (X, Y; E)\) be a bipartite graph with two vertex partition subsets \(X\) and \(Y\). \(G\) is said to be balanced if \(|X| = |Y|\) and \(G\) is said to be bipancyclic if it contains cycles of every even length from \(4\) to \(|V(G)|\). In this note, we present spectral conditions for the bipancyclic bipartite graphs.

Repeated sums and binomial coefficients

ODAM-Vol. 4 (2021), Issue 2, pp. 30 – 47 Open Access Full-Text PDF
Roudy El Haddad
Abstract:Binomial coefficients have been used for centuries in a variety of fields and have accumulated numerous definitions. In this paper, we introduce a new way of defining binomial coefficients as repeated sums of ones. A multitude of binomial coefficient identities will be shown in order to prove this definition. Using this new definition, we simplify some particular sums such as the repeated Harmonic sum and the repeated Binomial-Harmonic sum. We derive formulae for simplifying general repeated sums as well as a variant containing binomial coefficients. Additionally, we study the \(m\)-th difference of a sequence and show how sequences whose \(m\)-th difference is constant can be related to binomial coefficients.

Abstract: In this paper, we precise the hyper order of solutions for a class of higher order linear differential equations and investigate the exponents of convergence of the fixed points of solutions and their first derivatives for the second order case. These results generalize those of Nan Li and Lianzhong Yang and of Chen and Shon.

Abstract: The aim of this paper is to introduce strongest relation, cosets and middle cosets of anti \(Q\)-fuzzy subgroups of \(G\) with respect to \(t\)-conorm \(C.\) We investigate equivalent characterizations of them and we construct a new group induced by them, and give the homomorphism theorem between them.

Generalized fractional Hadamard type inequalities for \(Q_s\)-class functions of the second kind

OMS-Vol. 5 (2021), Issue 1, pp. 270 – 278 Open Access Full-Text PDF
McSylvester Ejighikeme Omaba, Louis O. Omenyi
Abstract: New Hadamard type inequalities for a class of \(s\)-Godunova-Levin functions of the second kind for fractional integrals are obtained. These new estimates extend and generalize some existing results for the \(Q\)-class and \(P\)-class functions. The generalized case for the Katugampola fractional integrals are also given.

Congruence properties of indices of triangular numbers multiple of other triangular numbers

OMS-Vol. 5 (2021), Issue 1, pp. 262 – 269 Open Access Full-Text PDF

Abstract: For any non-square integer multiplier \(k\), there is an infinity of triangular numbers multiple of other triangular numbers. We analyze the congruence properties of indices \(\xi\) of triangular numbers multiple of triangular numbers. Remainders in congruence relations \(\xi\) modulo \(k\) come always in pairs whose sum always equal \((k-1)\), always include 0 and \((k-1)\), and only 0 and \((k-1)\) if \(k\) is prime, or an odd power of a prime, or an even square plus one or an odd square minus one or minus two. If the multiplier \(k\) is twice the triangular number of \(n\), the set of remainders includes also \(n\) and \((n^{2}-1)\) and if \(k\) has integer factors, the set of remainders include multiples of a factor following certain rules. Algebraic expressions are found for remainders in function of \(k\) and its factors, with several exceptions. This approach eliminates those \(\xi\) values not providing solutions.

Abstract:The aim of this paper is to study 82 cases of nasal polyposis undergoing functional endoscopic sinus surgery (FESS). Our study comprised of 82 patients presenting with the symptoms of nasal polyposis (38 male patient, 44 female patients). All managed with FESS. Parameters assessed were NOSE score and nasal endoscopy score pre- operatively which was compared with post- operative score at 6 months and 12 months. We found pre-operative NOSE score was \(65.2\pm 5.7,\) at 6 months was \(28.4\pm 4.1\) and at 12 months post-operatively was \(24.2\pm 3.6.\) We found pre-operative nasal endoscopic score was 6.02, 6 months score was 3.1 and 12 months score was 2.5. We conclude that the patients nasal endoscopy score and NOSE symptom score was improved after treatment. Functional endoscopic sinus surgery is treatment of choice in patients with chronic rhinosinusitis with nasal polyps.

Abstract:Aim: To assess risk factors for development of type II diabetes. Materials & Methods: 80 patients of type 2 diabetes mellitus >40 years of age were put in group 1 group 2 were healthy subjects irrespective of gender. Factors such as family history, physical activity, blood pressure, alcohol consumption and BMI was recorded. Results: Alcohol consumption was present in 45 in group 1 and 20 un group 2, family history was positive in 65 group 1 and 12 in group 2, sedentary life was seen in 52 group 1 and 25 in group 2, BMI was underweight seen in 14 in group 1 and 5 in group 2, normal 12 in group 1 and 46 in group 2, overweight 30 BMI was underweight seen in 14 in group 1 and 5 in group 2, normal12 in group 1 and 14 in group 2 and obese 22 and 15 46 in group 2. Blood pressure was normal seen 16 in group 1 and 42 in group 2, pre- hypertension 24 in group 1 and 26 in group 2, hypertension stage 1 in 30 in group 1 and 10 in group 2 and hypertension stage 2 seen in 10 in group 1 and 2 in group 2. A significant difference was observed (P< 0.05). Conclusion: Common risk factors in diabetes was overweight, hypertension, lack of physical activity and alcohol consumption.

Evaluation of anesthetic management in renal transplant patients in a tertiary care centre

Robin Stein Seedat, Mohamed Al-Abri
Abstract:Aim: To evaluate anesthetic management in renal transplant patients. Methodology: Ninety- two renal transplant patients were part of the study. Parameters such as type of transplant, reason for chronic kidney disease, preoperative data, history of dialysis, preoperative anesthesia management, monitoring details and the outcome were recorded. Results: Chronic glomerulonephritis (CGN) in 28 (30.4%), chronic interstitial nephritis (CIN) in 20 (21.7%), polycystic kidney disease (PCKD) in 11 (11.9%), obstructive nephropathy (Ob. N) in 4 (4.3%), diabetic nephropathy (DN) in 8 (8.7%), hereditary nephropathy in 3 (3.2%), reflux nephropathy in 12 (13%) and membranoproliferative glomerulonephritis (MPGN) in 6 (6.5%). In 32 (35.6%) patients, isoflurane was inhalational agent and recovery time was 25.1 minute, in 40 (43.4%), desflurane was inhalational agent and recovery time was 22.7 minutes and in 20 (21.7%), sevoflurane was inhalational agent and recovery time was 32.1 minutes. A significant difference was observed (P< 0.05). Conclusion: Anesthesia management has made renal transplantation safe and predictable. Postoperative maintenance of renal transplant patients have contributed to the success of renal transplant programme.
