A method for the experimental measurement of bulk and shear loss angles in amorphous thin films

Brownian thermal noise is a limiting factor for the sensitivity of many high precision metrology applications, among other gravitational-wave detectors. The origin of Brownian noise can be traced down to internal friction in the amorphous materials that are used for the high reflection coatings. To properly characterize the internal friction in an amorphous material, one needs to consider separately the bulk and shear losses. In most of previous works the two loss angles were considered equal, although without any first principle motivation. In this work we present a method that can be used to extract the material bulk and shear loss angles, based on current state-of-the-art coating ring-down measurement systems. We also show that for titania-doped tantala, a material commonly used in gravitational-wave detector coatings, the experimental data strongly favor a model with two different and distinct loss angles, over the simpler case of one single loss angle

Magnetic Resonance Imaging in Non-traumatic Orbital Pathologies: An Observational Cross Sectional Study

Background: Orbital lesions form a wide range of pathologies, that create challenges in diagnosis, management and treatment. The high-resolution soft tissue detail provided by magnetic resonance imaging (MRI) has allowed for better lesion characterization. MRI is also important in the detection of extent and localization of orbital diseases. Aim: The aim of the study was to evaluate the profile of orbital lesions on MRI in non-traumatic orbital pathologies. The objectives of this study were to examine the MRI characteristics of common diseases arising from or extending into the orbit to aid in the correct diagnosis of orbital lesions. Material and Methods: The patient data was collected from GMC Jammu over a period of one year. The study comprises of 50 patients with symptoms of proptosis, orbital swelling, diminution of vision; referred from ophthalmology department of GMC Jammu. MRI examination was performed on Siemens Magnetom Symphony 1.5 Tesla machine and the cases were studied to determine the imaging features of various orbital pathologies on MRI. All patients were evaluated for the clinical symptoms and were also subjected to other routine investigations. Results: The most common presenting symptom was diminution of vision (66%) followed by proptosis (50%). Most commonly encountered lesions were infective and inflammatory lesions, contributing 60% of total lesions. Various other lesions encountered were coloboma, orbital lymphoma, vascular hemangiomas and thyroid ophthalmopathy. Conclusion: MRI is valuable for determining the extent of disease, describing its exact localisation and detecting involved orbital compartments. A compartmental approach to evaluating orbital disease can guide the differential diagnosis

To study the painless labour by epidural analgesia and its effects on cardiotocographic parameters and labour

Background: Epidural analgesia is a central nerve block technique achieved by injection of a local anesthetic close to the nerves that transmit pain and is widely used as a form of pain relief in labor. The objective was to study the effect of epidural analgesia on cardiotocographic parameters and relief of pain, effect on course of labor and its outcome in terms of duration, any complications and mode of delivery.Methods: A prospective observational study was done on 100 subjects. They were randomly divided into study and control groups, study group (50) were given epidural analgesia after 3cm dilatation while control group (50) did not receive any analgesic. NST was taken before and after analgesia, course of labor, duration of labor, mode of delivery.Results: The study shows no significant effect of epidural analgesia on the duration of labor, mode of delivery, and CTG parameters.Conclusion: Epidural analgesia group shows better pain relief. It favors normal course of labor, no effect on cardiotocographic parameters. Subjects in study group were more satisfied

Effect of anaemia on maternal and fetal outcome: an observational study

Background: Anaemia in pregnancy is a globally health-related issue that affects both mothers and their new-born. Hence an observational study to see the effect of anaemia on maternal and foetal outcome was conducted. Methods: 15024 mothers coming in OPD or IPD in past 4 years were recruited and their haemoglobin measured. Descriptive statistics was used for baseline characteristics. This observational study was conducted in department of obs and gynae, GSVM Medical College Kanpur from August 2018 to August 2022. All the data gathered was processed by SPSS version 25. Results: The main outcomes included 4 maternal outcomes (postpartum haemorrhage, shock, ICU admission, and maternal mortality) and 4 neonatal outcomes (foetal growth restriction, birth weight, NICU admission, stillbirth). 60.03% of the mothers were anaemic in our study. Maternal and foetal complications were more in anaemic than non-anaemic mothers with incidence of PPH, shock, ICU admission, and maternal mortality being 14.07%, 11.33% ,4.30 and 1.31% respectively than non-anaemic mothers with incidence of 11.22%, 7.26%, 1.76%, and 7.28% respectively. Foetal outcome was also poorer in anaemic mothers with incidence of FGR, LBW, NICU admission, Still birth being 3.15%, 8.85%, 12.96%, and 1.09% higher than non-anaemic group with incidence being 1.80%, 3.43%, 9.75%, and 0.30 % respectively. Conclusions: This observational study provides valuable insights into the effect of anaemia on both maternal and foetal outcomes. It emphasizes the importance of early detection and management of anaemia to mitigate the risks associated with this condition

Enhancing Quality of Life for Cancer Patients Through Innovations in Palliative Care

Cancer is still one of the main reasons people die around the world, and millions of people are dealing with both the sickness and the heavy physical, social, and mental effects that come with it. Survival rates for people with cancer have gone up thanks to progress in treatment, but the quality of life for many patients, especially those in the later stages of the disease, is still a major worry. Palliative care has become an important part of cancer treatment because it helps with all of a patient\u27s complaints, makes them more comfortable, and supports their general health. This essay looks at new ideas in hospice care that are meant to improve the quality of life for cancer patients. It focuses on individual care models, new treatments, and improvements in collaborative care methods. Recent improvements in hospice care have made patient-centered care, which considers each person\u27s tastes, cultural background, and unique needs, even more important. The most important thing that has changed hospice care is the use of technology, especially telemedicine, mobile health apps, and artificial intelligence. These tools make it easier to keep an eye on patients\u27 conditions all the time, talk to their doctors in real time, and handle their care more efficiently. They also allow for individual care plans that adapt to the changing needs of cancer patients. An important part of hospice care is pain management, which has also come a long way. New drug choices, like focused treatments and less invasive delivery methods, have helped to improve pain control. Adding alternative therapies like acupuncture, massage therapy, and music therapy to standard treatments has also been shown to help with complaints like nausea, tiredness, and worry, giving patients a more complete treatment plan. This essay also talks about the value of psychological support and the problems that cancer patients and their families face with their emotional and mental health. Cognitive-behavioural treatment, mindfulness, and coaching are some mental health therapies that have been shown to lower anxiety and improve general emotional well-being

Developing a Sustainability Index for Implementing Big Data Analytics in the Logistics Sector

This study identifies Critical Success Factors (CSFs) for implementing Big Data Analytics (BDA) for sustainable logistics practicesin the context of an emerging economy. Through a combination of literature review and experts' opinions, the study identifies 18CSFs essential for the effective application of BDA in the logistics sector. The identified CSFs are further classified into four major categories: Organizational Efforts (OE), Technological Capabilities (TC), Environmental Practices (EP), and Social Factors (SF)using TOE and stakeholders theory. With the help of experts, the identified CSFs are later ranked using the Best-Worst Method(BWM). A real-life Indian logistics company is studied to comprehend its existing operations, technological abilities, workforce competencies, and organizational environment. Further, the Graph Theory Matrix Approach (GTMA) is used to develop a sustainability index for analyzing the case study and expert remarks. The prioritization of CSFs under different categories can guide logistics companies in implementing BDA to achieve sustainability in logistics. The findings from the study reflect that OE and TC are the most important CSFs. The sustainability index value guides the evaluation of the current sustainability of the case company and assists in improving performance by benchmarking the best index values of the same industry. Logistics companies can learn from benchmarked companies and can adopt their strategies for achieving goals, simultaneously considering the ranking of identified CSFs for implementing BDA

Imaging insights in acute iron toxicity

Iron is more dangerous than most prescription medications, even though it is freely available, and is the leading cause of poisoning deaths in young infants. Imaging is important in early diagnosis and management of complications of iron poisoning, acute as well as long term. We report a case of 24-year-old female presenting with deliberate overdose of 30-40 iron (ferrous sulphate) tablets. We have discussed the role of X-ray abdomen and computer tomography in diagnosing iron poisoning. Despite treatment with deferoxamine chelation and hemodialysis, the patient's condition worsened over 72 hours, further progressing to multi-organ failure with refractory shock, culminating in cardiac failure. Despite aggressive supportive care, she succumbed to her illness. Autopsy findings revealed gastrointestinal mucosal erosion. A radiologist's role in diagnosing acute iron poisoning and assessing probable complication is significant
