Ideal theory of interval neutrosophic sets in subtraction algebras

OMS-Vol. 6 (2022), Issue 1, pp. 262 – 268 Open Access Full-Text PDF
V. S. Subha and P. Dhanalakshmi

Abstract: In this paper, we introduce the notion of interval neutrosophic ideals in subtraction algebras. Also, introduce the intersection and union of interval neutrosophic sets in subtraction algebras. We prove intersection of two-interval neutrosophic ideals is also an interval neutrosophic ideal. Some exciting properties and results based on such an ideal are discussed. Moreover, we define the homomorphism and homomorphism of interval neutrosophic sets. We prove the image of an interval neutrosophic subalgebra is also an interval neutrosophic sub-algebra.

Further on quantum-plank derivatives and integrals in composite forms

OMA-Vol. 6 (2022), Issue 2, pp. 130 – 138 Open Access Full-Text PDF
Ghulam Farid and Zeeshan Afzal

Abstract:In quantum-plank calculus, \(q\)-derivatives and \(h\)-derivatives are fundamental factors. Recently, a composite form of both derivatives is introduced and called \(q-h\)-derivative. This paper aims to present a further generalized notion of derivatives will be called \((q,p-h)\)-derivatives. This will produce \(q\)-derivative, \(h\)-derivative, \(q-h\)-derivative and \((p,q)\)-derivative. Theory based on all aforementioned derivatives can be generalized via this new notion. It is expected, this paper will be useful and beneficial for researchers working in diverse fields of sciences and engineering.

On the largest real root of the independence polynomial of a unicyclic graph

ODAM-Vol. 5 (2022), Issue 3, pp. 30 – 46 Open Access Full-Text PDF
Iain Beaton and Ben Cameron

Abstract: We find the maximum and minimum connected unicyclic and connected well-covered unicyclic graphs of a given order with respect to \(\preceq\). This extends 2013 work by Csikv’ari where the maximum and minimum trees of a given order were determined and also answers an open question posed in the same work. Corollaries of our results give the graphs that minimize and maximize \(\xi(G)\) among all connected (well-covered) unicyclic graphs. We also answer more related open questions posed by Oboudi in 2018 and disprove a conjecture due to Levit and Mandrescu from 2008. The independence polynomial of a graph \(G\), denoted \(I(G,x)\), is the generating polynomial for the number of independent sets of each size. The roots of \(I(G,x)\) are called the independence roots of \(G\). It is known that for every graph \(G\), the independence root of smallest modulus, denoted \(\xi(G)\), is real. The relation \(\preceq\) on the set of all graphs is defined as follows, \(H\preceq G\) if and only if \(I(H,x)\ge I(G,x)\text{ for all }x\in [\xi(G),0].\)

A fuzzy solution of nonlinear partial differential equations of fractional order

ODAM-Vol. 5 (2022), Issue 3, pp. 13 – 29 Open Access Full-Text PDF
Mawia Osman, Ahmed Hamoud, Altyeb Mohammed Mustafa, Zengtai Gong, Bchir Mahamat Acyl, Abdoulaye Ali and Bakry Musa

Abstract: In this paper, the fuzzy nonlinear partial differential equations of fractional order are considered. The generalization differential transform method (DTM) and fuzzy variational iteration method (VIM) were applied to solve fuzzy nonlinear partial differential equations of fractional order. The above methods are investigated based on Taylor’s formula, and fuzzy Caputo’s fractional derivative. The proposed methods are also illustrated by some examples. The results reveal the methods are a highly effective scheme for obtaining the fuzzy fractional partial differential equations.

Study of hemoglobin levels among pregnant women in different trimesters at a tertiary hospital

TCMS-Vol. 2 (2022), Issue 4, pp. 26 – 31 Open Access Full-Text PDF
Sradhamoni Kumbang, Archana Khanikar, Rumi Konwar and Siddhartha Sankar Konwar

Abstract: Background: Pregnancy increases the demand for nutrients and hemoglobin. Besides these, physiological changes in blood parameters also occurs during pregnancy. Anemia in pregnancy is a serious condition contributing to increased maternal and fetal morbidity and mortality. Present study has been undertaken with the knowledge of hemoglobin values and its distribution in different trimesters of pregnancy.
Material and Methods: Present study was single-center, prospective, comparative, parallel-group, observational study, conducted in pregnant women attended the ANC OPD or admitted in antenatal ward and sixty healthy non-pregnant women of same age group.
Results: The mean hemoglobin value was \(12.23\pm1.32 gm\) % throughout pregnancy. In control group the mean value was \(12.59 \pm 2.50 gm\)%. Statistically significant variation was observed between control and each trimester of pregnancy \((p<0.05)\). Significant difference observed between 1st and 2nd trimester \((p < 0.05)\) and 2nd and 3rd trimester \((p < 0.05)\). When compared between 1st and 3rd trimester, difference was not significant \((p>0.05)\) Hemoglobin values are lower in pregnant cases as compared to non-pregnant subjects \((p<0.05)\). Lowest hemoglobin value is observed in 2nd trimester in maximum number of cases. Mean hemoglobin level was found lower in pregnant women with gravidity more than 1 as compared to primigravidae.
Conclusion: A significant association was observed between hemoglobin level and trimester of pregnancy. High occurrence of low hemoglobin level in pregnant women was found belonging to lower socioeconomic class. Maternal hemoglobin value decreases with increase in gestational age.

COVID 19 associated mucormycosis: A curse in pandemic

TCMS-Vol. 2 (2022), Issue 4, pp. 18 – 25 Open Access Full-Text PDF
Dhruvika Rathva, Mayursinh Dodia, Atisha Modi and Saudhan Desai

Abstract: Aims: Mucormycosis is an acute invasive fungal infection which is rare, opportunistic and can potentially cause fatal complications. This study aimed to evaluate demographic data, disease presentation, medical &/or topical, surgical treatment.
Material and methods: Total twenty five patients with mucormycosis treated at tertiary care hospital in Gujarat during three months duration from May to July 2021. After detailed history thorough Ear, Nose and throat examination was performed. Along with local examination, ophthalmologic and neurologic examination performed in every case. After Functional endoscopic sinus surgery, tissue sent for histopathologic examination.
Results: Twenty five patients diagnosed with Mucormycosis, 18(72%) patients were males and 7(28%) were females. All 25(100%) had past history of COVID 19 infection and Diabetes Mellitus. Out of 25, 23(92%) patients were treated with intravenous or oral steroids and 2(8%) patients were not treated with any steroids. MRI paranasal sinuses with orbit with brain cuts performed for all 25 patients after suspicion of mucormycosis. 12(48%) patients had Sinonasal involvement, 11(44%) were Rhino-orbital involvement, and 2(8%) had Rhino palatal involvement. All 25(100%) patients were given Injection Amphotericin B for 3-4 weeks according to response. 6(24%) Patients were also given Oral Posaconazole. We performed Functional endoscopic sinus surgery in 23(92%) patients. In two (8%) cases Sinus surgery performed along with Maxillectomy. All 25(100%) cases on histopathology confirmed of Mucormycosis.
Conclusion: Prognostic factors we observed in our study were involvement of rhino-orbito-cerebral disease shows poor prognosis. Good Diabetes control showed early recovery. Early identification and early treatment improves prognosis as well as survival rates.
