at Selected Hospitals, Chennai
OBJECTIVES:
1. To assess the level of knowledge on lactation before and after virtual lactation management among control and experimental group of primi lactating mothers.
2. To assess the lactation practice before and after virtual lactation management among control and experimental group of primi lactating mothers.
3. To determine the effectiveness of virtual lactation management upon lactation by comparing the level of knowledge and lactation practice before and after the virtual lactation management among control and experimental group of primi lactating mothers.
4. To determine the association between selected demographic variables and level of knowledge and lactation practice before and after virtual lactation management among control and experimental group of primi lactating mothers.
5. To determine the association between selected obstetrical variables and level of knowledge and lactation practice before and after virtual lactation management among control and experimental group of primi lactating mothers.
6. To determine the level of satisfaction regarding the virtual lactation management among the experimental group of primi lactating mothers.
The conceptual framework for the study was developed based on the modified model of Wiedenbach’s helping art of clinical nursing theory. An experimental study of pre-test and post-test design was used. The study included 60 primi lactating mothers selected by simple random sampling. The present study was conducted at Andhra Mahila Sabha Hospital, Chennai. The variables of the study were virtual lactation management, knowledge and lactation practice.
An extensive review of literature and guidance by experts laid to the foundation of development of demographic variable proforma, obstetric variable proforma,
structured interview schedule, lactation practice observational checklist and rating scale on satisfaction of virtual lactation management. The data collection tools were validated and reliability was established. After two weeks of pilot study, then data collection for main study was conducted.
The level of knowledge and lactation practice was assessed for control and experimental group of primi lactating mothers. The Virtual lactation management of seven minutes duration was provided for the experimental group. Then the level of knowledge and lactation practice was assessed again after 7 days for both the groups. The level of satisfaction on virtual lactation management among the experimental group of primi lactating mothers was assessed after one week from intervention. The data obtained was analyzed using descriptive and inferential statistics.
MAJOR FINDINGS:
1. Majority of primi lactating mothers were 18 -23years old (76.66, 83.33%), Hindus (83.33%, 96.66%), qualified upto secondary education (60%, 63.33%), from nuclear family (90.00%, 80.00%), residing in urban area (100%, 100%). Large percentage of them were unemployed (63.33%, 76.66%) in control group and experimental group respectively.
2. Majority of primi lactating mothers had regular antenatal checkups (100%, 100%), none of the mothers had practiced antenatal nipple exercises (100%, 100%) and most of them did not have any complications during labour (86.66%, 93.33%). Majority of them practiced breastfeeding (93.33%, 96.66%) and most of them practiced demand feeding (36.66%, 43.33%). About more than half of the babies had an effective latch (50%, 56.66%) and good sucking (56.66%, 63.33%) in control and experimental group respectively.
3. Majority of the primi lactating mothers had inadequate knowledge before intervention (80%, 93.33%) in the control and experimental group respectively and all of them had adequate knowledge (100%) in experimental group after intervention.
4. The mean knowledge level was slightly high in the post test (M=10.8, SD=2.119) when compared to pre test (M=10.7, SD=2.246) in the control group where as the mean level of knowledge was high in the post test (M=23.3, SD=0.97) when compared to pre test (M=10.2, SD=1.81) in the experimental group.
5. Majority of mothers in pre test had poor practice with regard to lactation (100 %, 100%) in the control and experimental group. After the intervention the lactation practice was good in (63.33%) lactating mothers in experimental group. Hence null hypothesis H01 was rejected.
6. The mean score of lactation practice in the experimental group was high in post test (M=19.13, SD=1.8) in comparison with pre test (M=7.3, SD=1.242). Whereas in the control group there was only a minimal increase in the score of lactation practice (M=7.5, SD=1.403) during post test when compared with pre test (M=7.4, SD=1.518).
7. There was no significant association between age in years, educational status, type of employment and type of family with level of knowledge in experimental and control group of primi lactating mothers. Hence null hypothesis H02 is retained.
8. There was no association between age in years, educational status, type of employment and type of family and lactation practice in control group of primi lactating mothers but there is significant association between type of family and lactation practice in experimental group of primi lactating mothers. Hence null hypothesis H02 was partially rejected.
9. There was no significant association between effective latch of the baby, type of
delivery, initiation of breast feeding and frequency of feeding with level of knowledge and lactation practice in control and experimental group of primi lactating mothers. Hence the null hypothesis H03 was retained.
10. All the participants in the experimental group were satisfied (100%) with the virtual lactation management intervention.
RECOMMENDATIONS:
1. The same study can be conducted with large number of samples to generalize results.
2. A comparison can be made between primi and multi gravidae mothers.
3. The same study can be conducted in different settings.
4. A comparison can be made between different types of educational programmes
Band Gap Tuning of DC Reactively Sputtered ZnON Thin Films
Zinc oxynitride (ZnON) has recently emerged as a highly promising
band gap-tunable semiconductor material for optoelectronic applications. In
this study, a novel DC reactive sputtering protocol was developed to fabricate
ZnON films with varying elemental concentrations, by precisely
controlling the working pressure. The band gap was rigorously analyzed using
UV-Visible spectroscopy, which was complemented by EDAX spectroscopy to
determine the variations in the elemental composition. The correlation between
the microstructure and band gap was investigated through the application of
AFM, XRD, and Raman spectroscopy, while the Urbach theorem was used to evaluate
the defect states. This study revealed the existence of intermediate structures
formed during the tuning of the band gap, which can have important implications
for future research aimed at developing heterostructures and 2D superlattices
for photonics applications
Searches for IceCube Neutrinos Coincident with Gravitational Wave Events
Searches for neutrinos from gravitational wave events have been performed
utilizing the wide energy range of the IceCube Neutrino Observatory. We discuss
results from these searches during the third observing run (O3) of the advanced
LIGO and Virgo detectors, including a low-latency follow-up of public candidate
alert events in O3, an archival search on high-energy track data, and a
low-energy search employing IceCube-DeepCore. The dataset of high-energy tracks
is mainly sensitive to muon neutrinos, while the low energy dataset is
sensitive to neutrinos of all flavors. In all of these searches, we present
upper limits on the neutrino flux and isotropic equivalent energy emitted in
neutrinos. We also discuss future plans for additional searches, including
extending the low-latency follow-up to the next observing run of the
LIGO-Virgo-KAGRA detectors (O4) and analysis of gravitational wave (GW) events
using a high-energy cascade dataset, which are produced by electron neutrino
charged-current interactions and neutral-current interactions from neutrinos of
all flavors.Comment: Presented at the 38th International Cosmic Ray Conference (ICRC2023).

Rotating Bose-Einstein Condensate Stars at finite temperature
We study the effect of temperature on the global properties of static and
slowly rotating self-gravitating Bose-Einstein condensate (BEC) stars within
general relativity. We employ a recently developed temperature dependent BEC
equation of state (EoS) to describe the stellar matter by assuming that the
condensate can be described by a non-relativistic EoS. Stellar profiles are
obtained using general relativistic Hartle-Thorne slow rotation approximation
equations. We find that with increasing temperatures mass-radius values are
found to be decreasing for the static and rotating cases; though presence of
temperature supports high mass values at lower central densities. Countering
effects of rotation and temperature on the BEC stellar structure have been
analysed and quantified. We report that inclusion of temperature has
significant effect on the rotating stellar profiles but negligible effect on
the maximum mass, as in the case of static system. We have also studied the
effect of EoS parameters -- boson mass and strength of the self-interaction --
on global properties of static and rotating BEC stars, in presence of
temperature.Comment: 12 pages, 10 figures; accepted for publication in Phys. Rev.
InSAR as a tool for monitoring hydropower projects: A review
This paper provides a review of using Interferometric Synthetic Aperture Radar (InSAR), a microwave remote sensing technique, for deformation monitoring of hydroelectric power projects, a critical infrastructure that requires consistent and reliable monitoring. Almost all major dams around the world were built for the generation of hydropower. InSAR can enhance dam safety by providing timely settlement measurements at high spatial-resolution. This paper provides a holistic view of different InSAR deformation monitoring techniques such as Differential Synthetic Aperture Radar Interferometry (DInSAR), Ground-Based Synthetic Aperture Radar (GBInSAR), Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR), Multi-Temporal Interferometric Synthetic Aperture Radar (MTInSAR), Quasi-Persistent Scatterer Interferometric Synthetic Aperture Radar (QPSInSAR) and Small BAseline Subset (SBAS). PSInSAR, GBInSAR, MTInSAR, and DInSAR techniques were quite commonly used for deformation studies. These studies demonstrate the advantage of InSAR-based techniques over other conventional methods, which are laborious, costly, and sometimes unachievable. InSAR technology is also favoured for its capability to provide monitoring data at all times of day or night, in all-weather conditions, and particularly for wide areas with mm-scale precision. However, the method also has some disadvantages, such as the maximum deformation rate that can be monitored, and the location for monitoring cannot be dictated. Through this review, we aim to popularize InSAR technology to monitor the deformation of dams, which can also be used as an early warning method to prevent any unprecedented catastrophe. This study also discusses some case studies from southern India to demonstrate the capabilities of InSAR to indirectly monitor dam health
