A Novel CPW Fed MIMO Antenna for UWB Applications

This paper presents two planar antennas designed from a compact novel CPW fed UWB antenna. The first antenna is single UWB antenna. The single UWB antenna covers the entire UWB frequency band. Single antenna operates in 2.8 GHz to 12.6 GHz. The second antenna is MIMO antenna which is made with orthogonal placement of two UWB antennas and MIMO antennas covers the entire UWB frequency band. The MIMO antenna with orthogonal placement of antennas operates in 2.9 GHz to 12.7 GHz band. The designed single antenna has dimensions of 27 X 34 X 1.6 mm3 and MIMO antennas have volume of 61 X 34 X 1.6 mm3 for orthogonal placement. Antenna has satisfactory performance in terms gain, radiation pattern, return loss, voltage standing wave ratio, envelope correlation coefficient and diversity gain for UWB MIMO application

Računanje vrpčaste strukture nelokalnim pseudopotencijalima

Energy bands of Rb and Cs have been calculated for the first time using average or effective pseudopotentials obtained from non-local ones. It is shown that the results so obtained compare well to those obtained with full non-local calculations.Načinili smo prve račune energijskih vrpci Rb i Cs primjenom prosječnog ili efektivnog pseudopotencijala koji smo izveli iz nelokalnih pseudopotencijala. Pokazuje se dobra suglasnost ishoda tih računa i računa primjenom potpunih nelokalnih pseudopotencijala

Theoretical study of pressure dependence of superconducting state parameters of some metals using pseudopotential approach

In the present theoretical study, we have calculated superconducting state parameters (SSPs) viz; electron-phonon coupling strength (λ), Coulomb pseudopotential (µ*), critical temperature (Tc), effective interaction strength (N0V) and isotopic effect parameter ( α) of some polyvalent metals (Pb, Ga, In, Sn and Tl) using well-established structured local pseudopotential due to Fiolhais et al. (1995). The pseudopotential with its individual set of parameters has been found to be good in predicting transition temperature Tc for all the metals. Looking to such success, we have extended the present model for the theoretical study of pressure dependence of transition temperature Tc using Debye- Gruneisen model. Our predicted critical volumes using different approaches are well agreed with each other and also with other reported findings. Thus, the present model is consistent and better than nonlocal norm conserving pseudopotentials because it is found to be transferable without any kind of adjustment of its parameters along with its simplicity and predictivity

A clinical study on fetomaternal outcome in jaundice with pregnancy

Background: Jaundice in pregnancy and pregnancy in women with preexisting liver disease is not very uncommon. However it takes a major toll on health of both mother and fetus, due to increased morbidity and mortality for both mother and fetus, categorizing pregnancy as a high risk one. The distribution of jaundice in pregnancy varies throughout the world, but is seen more in developing countries. The course and outcome of liver disorder in pregnancy is altered due to various hemodynamic, hormonal and immunological changes unique to pregnancy. The hepatic functions during pregnancy are affected by increase in serum estrogen and progesterone levels.Methods: This was a prospective study of 70 cases of pregnancy with jaundice admitted in the department of obstetrics and gynecology at Sheth V.S. General Hospital, Ahmedabad, Gujarat, India. The duration of study was from June 2015 to December 2018. During this period 70 patients were admitted with jaundice in pregnancy. Patients were analyzed with regards to socio demographic profile, investigations, maternal and perinatal outcome.Results: The incidence of pregnancy with jaundice in present study was 0.32%. Most common cause identified was viral hepatitis in 27 cases (38.57%) out of which 23(32.85%) cases being hepatitis E. Followed by HELLP syndrome, pre eclempsia, eclempsia in 24(34.28%) cases. 13(18.57%) cases were belonged to cholestatic jaundice of pregnancy. Rest 6(8.56%) cases belonged to malaria, portal hypertension due to liver disease etc. Out of total 70 patients 53(75.71%) women from rural area, 54(77.13%) patients were from age group of 20-29years.Maximum patients were multigravida i.e. 28 (40%) and 66(94.28%) women coming from lower middle and lower socio economic class. There were 9 maternal deaths, 5 due to DIC. Total vaginal deliveries were 40, 24 patients underwent LSCS, 4 patients had abortion, and 2 expired undelivered. Most common complication was DIC in 16(22.85%) cases and thrombocytopenia in 14(31.67%) cases. 30(42.85%) babies were LBW and 18(25.7%) babies were IUGR.Conclusions: Prompt diagnosis and accurate evaluation and multidisciplinary approach of management in pregnancy with jaundice at a tertiary care center with good NICU is helpful in reducing maternal and perinatal mortality and morbidity

An overview of the predictors of symptomatic urinary tract infection among nursing students

Background: Urinary tract infection (UTI) is the most common infection experienced by humans after respiratory and gastro‑intestinal infections, and also the most common cause of nosocomial infections for patients admitted to hospitals indeed UTIs are the most frequent bacterial infection in women. Aim: The aim was to determine the prevalence of UTI and to identify factors associated with an increased risk of UTI among nursing students. Subjects and Methods: The cross‑sectional study involved 177 unmarried nursing students aged 18–30 years studying in the SRMSIMS, Nursing College Bareilly. A structured questionnaire was used, and study subjects were asked regarding the symptoms of UTI in the previous 3 months. Chi‑square test and Univariate Logistic Regression was used to analyze the data. Results: The overall prevalence of UTI was found to be 19.8% (35/177). Rural background, inadequate water intake, and unsatisfactory toilet habits were found to be strong predictors of UTI. Conclusions: There is an urgent need to sensitize the nursing students regarding the growing need of the issue so that they themselves become aware in addition to raising the awareness of other high‑risk groups.Keywords: Nursing students, Prevalence, Urinary tract infectio
