Abstract

In present work, joint flexibility (or looseness) of the free-free beam is investigated by using a two noded beam finite element formulation with transverse displacement and joint rotations as the degrees of freedom per node at joint location. Flexibility of the joint is primarily represented by means of a rotational spring analogy, where the stiffness of the rotational spring characterizes the looseness of the flexible joint for an applied bending moment. Influence of joint location as well as joint stiffness on modal behavior of first five modes of slender, uniform free-free beams are discussed for various values of non-dimensional rotational spring stiffness parameter. Numerical accuracy of the results obtained from the present finite element formulation are validated by using the commercially available finite element software which shows the confidence gained on the numerical results discussed in the present study.

Abstract

Myxoid liposarcomas metastatic to lungs and mediastinum are infrequent lung neoplasms. The tumor has an aggressive course and needs to be recognized cytologically. A 60-year-old male smoker presented with gradually progressive left-sided chest pain, cough, and expectoration for the past one month. Chest radiograph and computed tomography of thorax revealed a lung mass in left apical region extending into the posterior mediastinum, which was subjected to ultrasound-guided fine needle aspiration (FNA). Smears showed a cellular tumor with ovoid to spindle shaped tumor cells in a myxoid background having a rich vascular network. The possibility of a myxoid liposarcoma metastatic to lung and mediastinum was suggested and confirmed by histopathology. A previous history of excision of a tumor in the thigh one and half years ago was present. The importance of recognizing the cytological picture by FNA is discussed.

Abstract

Back ground: Infants who are born to Diabetic mothers have been found to be at a significantly increased risk for perinatal morbidity and mortality risks. The improvement of the outcome of diabetes pregnancies through the use of appropriate maternal glycaemic control has been a goal for doctors. Materials and Methods: Prospective observational study was conducted in Department Of Pediatrics, Kurnool Medical College and Government General Hospital from January 2021 - December 2022. The data of IDMs were collected from postnatal ward. All IDMs delivered during this period staying in postnatal ward were included in this study. The outcomes were compared between the hypoglycaemic and normoglycemic IDMs and between gestational diabetes mellitus (GDM) and pre-GDM in hypoglycaemic group using Chi-square test and Fisher's exact test. The data analysis was performed with Epi-enfo7 software. Statistical significance was set at P < 0.05. Results: Out of 100, 16.25% had birth weight more than 4 Kg, 60% had hypoglycaemia. 23.75% of neonates are Large for gestational age, 45% developed hypocalcaemia and 43% developed hyperbilirubinemia. 62% had polycythaemia, congenital anomalies in 15%, 8.75% had birth injuries, incidence of mortality was 10%. Conclusion: GDM and ODM are common metabolic disorders in pregnancy which cause variety of neonatal complications. All pregnant mothers must undergo diabetes screening. They need better glycaemic management and regular follow-up. Delivery should be planned in order to decrease the risk of shoulder dystocia and birth injuries, and the rate of emergency caesarean sections. To enhance newborn outcomes, all babies born to mothers with diabetes should be admitted to the neonatal care unit for observation. Need special attention to mothers for GDM prevention and DM therapy. [ABSTRACT FROM AUTHOR]

Abstract

Fixed power sum of positive integers is a well-known problem in number theory. Here we have given a brief history about it by mentioning the contributions of some eminent mathematicians. An internal relation between Σλ and Σλ3 has been traced in an geometric approach and the authors are strongly believing that this geometric approach can give a generalized result for Σλn. Pascal's recurrence relation has been proposed with illustrative examples. Moreover a recurrence relationship is presented by the authors using binomial theorem and they are concluding that any fixed power sum can be easily carried out with this relationship. More importantly by applying binomial theorem we have proved that any fixed power sum is a unique polynomial over rational numbers. Finally an explicit formula has been proposed and this can give any power sum formula. [ABSTRACT FROM AUTHOR]

Subjects
MATRIX decomposition
Abstract

SVD is a most powerful concept extensively used in a large number of models. It plays an important role in PCA. As it describes the factorization of matrix, it is also used in matrix completion. Hence we proposed the concept of SVD here with an illustrative example. If a linear system has no solution, the pseudo-inverse will help us in finding the BEST-FIT solution. In new of this, we (the authors) presented the mathematical concept behind it and shown one illustrative example. [ABSTRACT FROM AUTHOR]

50. Valence band and core-level analysis of highly luminescent ZnO nanocrystals for designing ultrafast optical sensors

Author

Subjects

Abstract

Highly luminescent ZnO:Na nanocrystals of size ~2 nm were synthesized using a improved sol-lyophilization process. The surface analysis such as survey scan, core-level and valence band spectra of ZnO:Na nanocrystals were studied using x-ray photoelectron spectroscopy (XPS) to establish the presence of Na+ ions. The observed increase in band gap from 3.30 (bulk) to 4.16 eV (nano), is attributed to the quantum confinement of the motion of electron and holes in all three directions. The photoluminescence and decay measurements have complemented and supported our study to design an efficient and ultrafast responsive optical sensing device., Comment: 10 Pages, 5 Figures
