Variation of cross section with special points for 16O(5/2+) and 16O(1/2+) states in Alt Grassberger Sandhas version of Faddeev approach
Gauss Legendre special points and weights play a prime role in calculating the cross sections of nuclei in the excited states upto some extent. The inputs taken in these calculations are the separable form of T-matrix and the coupled angular momentum basis. The deuteron is considered to be a mixture of singlet as well as triplet states. The form of the potential is Wood–Saxon type and the parameters are fitted by Reid Soft Core potential. The main objective of our work is to show how the cross section varies with respect to the Gauss Legendre’s special points in terms of fermi
Specific parameters for some isotopes of copernicium and flerovium
Super heavy elements (SHE) in the periodic table are generally transuranic and transactinide elements having Z > 92. Here, some of the properties of two super heavy elements viz. Copernicium (Cn) and Flerovium (Fl) are discussed. The half life time, transition probability, Gamow’s factor, disintegration constant are calculated for these super heavy elements and compared with other values
Separation energies of light nuclei with atomic number from 1 to 20
The 1n and 1p halo nuclei from atomic number 1 to 20 are discussed here to calculate the variation of separation energy with mass defect and binding energy. Semi-empirical mass formula and shell model are the methods applied here. The appearances of p- and r-branches satisfying the selection rules for different isotopes of nuclides are discussed
Acute Kidney Injury among Patients Visiting the Nephrology Unit in a Tertiary Care Centre: A Descriptive Cross-sectional Study
Introduction: Acute kidney injury is an abrupt decline in renal function often associated with a decrease in urine output. It is the leading cause of in-hospital mortality worldwide with prolonged hospital stays, the requirement of mechanical ventilation and short-term dialysis. The aim of the study was to find out the prevalence of acute kidney injury among patients visiting the Nephrology unit in a tertiary care centre.
Methods: This descriptive cross-sectional study was done among patients presented to the Nephrology Unit of the Department of Internal Medicine in a tertiary centre from 9 February 2022 to 21 October 2022. Ethical approval was taken from Institutional Review Committee (Reference number: UCMS/IRC/047/22). Data was collected from hospital records and the outcome was recorded in terms of in-hospital mortality and the requirement for renal replacement therapy. Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated.
Results: Among 1848 patients, 113 (6.12%) (5.03-7.21, 95% Confidence Interval) had acute kidney injury. About 38 (32.75%) required inotropes whereas 10 (8.85%) required mechanical ventilation. In-hospital all-cause mortality was seen in 14 (12.39%) of the study population and 20 (17.70%) of the study population required renal replacement therapy. The most common cause of acute kidney injury was infection pneumonia followed by acute gastrointestinal infections were the most common infective aetiology.
Conclusions: The prevalence of acute kidney injury was found to be lower than the studies done in similar settings. It is common in patients admitted with infection. It is responsible for in-hospital mortality
TRANSITION PROBABILITY IN RESONANCE CONDITION FOR Z=110
The transition probability for different states are found out for the isotopes of z=110.The half-life are also calculated and it is seen that the stable form of isotope is A=281 ,z=11
RATIO OF CROSS SECTIONS OF ELEMENTARY STRONG REACTIONS USING CLEBSCH GORDON (CG) CO-EFFICIENTS
An The strong reactions having certain properties obeying the conservation laws of isospin, baryon number, lepton number, strangeness, hypercharge etc are considered. The clebsch Gordon coefficients for SU(3) symmetry group satisfying orthogonal properties are expressed. The cross sections are found out in terms of these co-efficients

Detection of <i>Streptococcus pneumoniae</i>, <i>Neisseria meningitidis</i> and <i>Haemophilus influenzae</i> in Culture Negative Cerebrospinal Fluid Samples from Meningitis Patients Using a Multiplex Polymerase Chain Reaction in Nepal
The rapid identification of bacteria causing meningitis is crucial as delays in the treatment increase mortality rate. Though considered as the gold standard for the laboratory diagnosis of bacterial meningitis, culture might give false negative results in a case of patients under antibiotics prior to lumbar puncture. This study aimed to detect Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae by a multiplex polymerase chain reaction (PCR) in culture-negative cerebrospinal fluid samples collected from clinically suspected meningitis cases attending different hospitals in Kathmandu, Nepal from January 2017 to December 2019. S. pneumoniae, N. meningitidis and H. influenzae were detected in 8.59% (33/384) of the specimens by PCR and 7.55% (29/384) of the specimens by culture. Correlation between culture and PCR of the same sample was good (Spearman’s rho correlation coefficient = 0.932). However, the difference in positivity between culture and PCR was statistically not significant (p value > 0.05). In four specimens, culture could not detect any of the targeted bacteria whereas PCR could detect presence of H. influenzae. PCR increases the diagnostic yield for bacterial meningitis. PCR may be considered as an adjunctive test for establishing the cause of infection in culture negative clinically suspected meningitis cases
