Determination of structural elements of synthesized silver nano-hexagon from X-ray diffraction analysis

Silver nano-hexagons (AgNHs) have been prepared by a chemical reduction method using poly-vinyl pyrrolidone (PVP) as a stabilizing agent. The XRD results exhibit the crystalline nature of the prepared sample, with a face centred cubic (fcc) phase. Transmission electron microscopic (TEM) results reveal that the silver nanoparticles are nearly hexagon in shape with an average size of 50 nm. Here, crystallite size has been calculated using Williamson-Hall (W-H) method, which is nearly matching with average size obtained from TEM analysis. Again, using W-H method, micro strain has been calculated, which is produced in the nano-hexagon due to dislocation of silver atoms. Further, the lattice constant of the nano-hexagons has also been estimated from the Nelson–Riley plot. Moreover, the appropriate structural parameters such as Lorentz factor, Lorentz polarization factor, dislocation density, number of atoms in a unit cell and morphological index have also been studied from the X-ray diffraction profile

GENERALIZATIONS OF RAMANUJAN'S RANK FUNCTIONS COLLECTED FROM RAMANUJAN'S LOST NOTEBOOK

In1916, Srinivasa Ramanujan defined the Mock Theta functions in his lost notebook and unpublished papers. We prove the Mock Theta Conjectures with the help of Dyson’s rank and S. Ramanujan’s Mock Theta functions. These functions were quoted in Ramanujan’s lost notebook and unpublished papers. In1916, Ramanujan stated the theta series in x like A(x), B(x), C(x), D(x). We discuss the Ramanujan’s functions with the help of Dyson’s rank symbols. These functions are useful to prove the Mock Theta Conjectures. Now first Mock Theta Conjecture is “The number of partitions of 5n with rank congruent to 1 modulo 5 equals the number of partitions of 5n with rank congruent to 0 modulo 5 plus the number of partitions of n with unique smallest part and all other parts the double of the smallest part”, and Second Mock Theta Conjecture is “The double of the number of partitions of with rank congruent to 2 modulo 5 equals the sum of the number of partitions of with rank congruent to 0 and congruent to1 modulo 5, and the sum of one and the number of partitions of n with paper shows how to prove the Theorem 1.3 with the help of Dyson’s rank symbols N(0,5,5n+1), N(2,5, 5n+1) and shows how to prove the Theorem 1.4 with the help of Ramanujan’s theta series and Dyson’s rank symbols N(1,5, 5n+2), N(2,5, 5n+2) respectivel

Asymptotic analysis of Feynman diagrams and their maximal cuts

The ASPIRE program, which is based on the Landau singularities and the method of power geometry to unveil the regions required for the evaluation of a given Feynman diagram asymptotically in a given limit, also allows for the evaluation of scaling coming from the top facets. In this work, we relate the scaling having equal components of the top facets of the Newton polytope to the maximal cut of given Feynman integrals. We have therefore connected two independent approaches to the analysis of Feynman diagrams.Comment: 34 pages latex, 7 figures and 2 tables, ancillary Mathematica files provided, substantially extended and improved, added new sections(sub-section-2.5, section-3,4,appendix-B), References added, version accepted for publication in EPJ

Electromyographical Analysis of The Thigh Muscle During Four Yogasana

The goal of the study was to examine the peak EMG at four lower body muscles during four different yoga poses performed by yoga practitioners. Materials and methods: Male Yoga practitioners (n= 11) were assessed for peak electromyography (EMG) of VM-Vastus Medialis, VL- Vastus lateralis, BF- Biceps femoris, ST- Semitendinosus, while performing four Yogasana: UK- Utkatasana, VB- Virabhadrasana II, UPE- Urdhva prasarita ekapadasana six, DOL- Dolasana (pendulum pose). Results: The UK induced the highest EMG for VM (124.5000 ± 25.36088), VL(124.2364 ± 27.35410), ST (106.6091 ± 32.77619),BF (96.6909 ± 29.34824),The VB II induced the highest EMG for the VL (102.0727 ± 32.96262), VM (100.4091± 16.30960), BF (84.5727 ± 28.63844), ST (86.2818 ± 26.07239).The UPE-Six induced the highest EMG for the VM (42.4364 ± 17.09025), BF (45.0636 ± 21.33440),ST (39.3727 ± 17.03315),VL (38.3636 ± 20.73612).The DOL induced the highest EMG for the VM (88.7455 ± 56.13069), BF (65.2545 ± 36.53172), ST (62.6455 ± 19.28302),VL (43.2545 ± 24.14255). However, between Yogasana, only the VM showed a significant (P < .000) * different EMG. Specifically, the UK induced greater VM EMG compared to UPE (82.064, P < .000), VB (57.973, P < .000) * Conclusions: Peak muscular activation in the four lowerbody muscles can change depending on how the yoga players treat the four differences. A declining pattern of peak EMG for the UK > VB II > DOL and UPE six Yogasana, however, indicates that variations between poses appear to be minimal, with the exception of the VM muscle

Effect of Early versus Delayed Cord Clamping on Hematological Parameters of Term Neonates: Pengaruh Penjepitan Tali Pusat Dini Dibandingkan dengan Tertunda pada Parameter Hematologi Neonatus Aterm

Objectives : To compare the serum bilirubin, hemoglobin, and hematocrit in term infants undergoing delayed cord clamping with early cord clamping after normal and caesarean delivery.Methods : This is a prospective observational study. The neonates in which cord clamping was done within 15 seconds were considered in early cord clamping (ECC) group and where cord clamping was done after 1 minute was considered in delayed cord clamping (DCC) group. The PCV, Hb, serum bilirubin were observed after 48 hours in both the groups and compared.Results : There was statistically significant difference in means of Hb level (p = 0.001) and PCV level (p = 0.001) between DCC and ECC group whereas no statistically significant difference was present in total serum bilirubin level (p = 0.359).Conclusion: There was no significant increase in risk of polycythaemia and hyperbilirubinemia between delayed cord clamping and early cord clamping group rather has beneficial effects in increasing the haemoglobin and haematocrit in the infants.Keywords : delayed cord clamping, early cord clamping, hematocrit, hemoglobin, serum bilirubin, hyperbilirubinemia. Abstrak Tujuan: Untuk membandingkan bilirubin serum, hemoglobin, dan hematoklit pada bayi aterm yang dilakukan delayed cord clamping dan early cord clamping setelah persalinan normal dan seksio sesarea.Metode: Studi ini merupakan studi prospektif.

The role of anthropometric variables in assessment of obesity among Tripuri women of North-East India

Obesity is an etiologically complex and multifactorial phenotype, underpinned by genetic, environmental, socioeconomic and behavioural or psychological factors. Worldwide prevalence of obesity is reaching epidemic or pandemic proportions, which has resulted in an increased prevalence of obesity-related co-morbidities and financial burden that needs effective interventions. The prevalence of obesity varies significantly across the world, and several studies have been conducted in this regard in different regions on different age groups, but studies on the tribal female population of Northeast India are underrepresented, being mostly limited to schoolchildren. Under these circumstances, the present study was conducted to assess the prevalence of obesity among the tribal females of Tripura, Northeast India. To achieve this purpose, the present study was conducted on 114 adult Tripuri females of Northeast India. Data were collected on anthropometric variables – height, weight, waist circumference (WC), and hip circumference (HC) – by using the standard technique. Then, from these anthropometric measurements, a number of indices – waist-stature ratio (WSR), body mass index (BMI), conicity index (CI) and waist-hip ratio (WHR) were calculated. The necessary descriptive and inferential statistics were calculated by using SPSS version 18. The present study vindicated that only 22% women were overweight as per BMI, but 88% and 72% women were in the high-risk category on the basis of WHR and WSR respectively. Moreover, 86% of the females were biconic, which indicates higher prevalence of central obesity among the studied population. Therefore, it can be concluded that anthropometric variables can be used as one of the efficient tools to assess obesity and health status of the Tripuri women. More in-depth studies using large samples and other different anthropometric indicators are required for better insightful approach towards ethnic group specific public health policy making
