Beneficiation and Development of Process Flowsheet of High Ash Non-Coking Coal from Talcher Coalfield, Odisha

In India, Coal is the irreplaceable preferred energy fuel due to its abundance, availability and affordability and it would continue to be so in the foreseeable future. Around 73% of the entire power generated in the country is coal based, which bears testimony to the immense significance of coal in India’s economic growth and development. However, Indian coal has been observed to be of low quality on account of its high ash content attribute and non-coking category coal constitutes sizeable quantity of near-gravity materials (NGM), which entails beneficiation, to suit end-users. The objective of the present study demonstrates beneficiation of high ash non-coking coal from Talcher coalfield, Odisha, with 34.31% ash content intended for scaling down the ash content to 25% in obtaining clean coal at a reasonable yield, deploying physical beneficiation techniques. The coal sample was characterised thoroughly in terms of petrography, size analysis, washability and chemical composition. Beneficiation process was initiated at a top size of 6.3 mm due to its high ash content. Tactical combination of gravity separation and flotation techniques yielded clean coal with 23.3% ash at 49.7% yield, an intermediate clean product with 30.9% ash at 12.1% yield and a reject with 49.8% ash at 38.2% yield

"Enhancing Perinatal Outcomes In Gestational Diabetes Mellitus: A Midwifery Facilitator Based Approach"

Introduction: Gestational diabetes mellitus, or GDM, is a metabolic disorder that affects both expectant mothers and their developing fetuses. It increases the chance of several pregnancy and delivery complications. Babies born to women with gestational diabetes mellitus (GDM) are at risk for perinatal death, fetal macrosomia, low blood sugar, birth trauma, and congenital malformations. This paper explores the possibility of enhancing perinatal outcomes in GDM by applying a midwifery facilitator-based approach. Objectives: This study's primary objective is to assess the impact of a midwife facilitator-based approach on the management of gestational diabetes mellitus (GDM) and its associated complications in expectant mothers and their babies. Our objective is to create a midwifery facilitator approach model that provides recommendations for clinical practice. Methods: A prospective cohort study involving 111 mothers compared standard care with care led by midwives. The intervention group was chosen based on their preferences, and they received full support, which included education, lifestyle modifications, and assistance for mothers. A certified diabetes educator led the classes, which covered a variety of subjects like multiple pregnancies, chronic illnesses, and absences. Group 1 comprised 62 mothers who attended classes and follow-ups, while 49 mothers in Group 2 did not attend any of them. Consistency and low turnover were assured. Results: The Midwifery Facilitator-Based Approach, which considers psychological, emotional, and physical factors, fully manages GDM. Strict diabetes management, nutritional counseling, promoting a healthy diet, and aiding in stress reduction are all made possible by these midwives. They empower mothers with GDM to take care of themselves and allow informed decision-making, potentially improving perinatal outcomes and the general well-being of GDM-affected families. Conclusion: A promising strategy for improving perinatal outcomes in GDM is the facilitator-based approach used by midwives. It offers a treatment plan that is holistic in nature, taking into account the relationships between various aspects of health. By integrating midwifery into GDM management, we can enhance mothers' empowerment and comprehension, which will ultimately benefit moms and their infants

Versatility of antero-lateral thigh free flap in reconstruction of defects in different parts of body - our experience

Extensive soft tissue defects pose a great deal of challenge to the reconstructive surgeon. The aim of this study is to analyze the outcome of free anterolateral thigh (ALT) flaps for soft tissue reconstruction of defects following tumor excision, trauma and post burn. A retrospective review of 19 patients undergoing ALT Flaps for various reasons from Dec 2018 to Jan 2021 was performed to determine perioperative factors, demographic profile, complications and outcomes. The mean age of the study population was 47.2 years. The male to female ratio was 2.16:1 (68.5 % male, 31.5% females). The etiology of soft tissue defect was post-tumor resection-47.36%, truam-36.8%, post burn reconstruction-10.5%. The defect sites were most commonly leg-31.5%, upper extremity-26.3%, buccal mucosa-15.7%, scalp-10.5%, tongue-10.5%, breast-5.2%. Flaps were harvested from right thigh in 52% of cases and left thigh in 58% of the cases. Donor site was closed primarily in 11 cases (57.8%), SSG coverage was done for 8 cases (42.8%). The minimum hospital stay post op was 12 days, maximum being 45 days. Postoperative complications were seen in 36.8% of the cases. Partial flap necrosis occurred in 3 cases (15.7%), complete necrosis in 1 case (5.2%), donor site morbidity was seen in 3 cases (15.7%). In the post-operative period hematoma and infection occurred in 3 cases. ALT Flap in experienced hands provide reliable coverage of large soft tissue defects with excellent aesthetic and functional outcomes with minimal donor site morbidity.

Assessment of the recurrent mutagenesis efficacy of sesame crosses followed by isolation and evaluation of promising genetic resources for use in future breeding programs

The primary causes of low sesame production are a lack of high-yielding varieties, an inability to adjust to environmental challenges, and a poor response to enhanced crop management. The potential for improving sesame has been investigated using a variety of breeding approaches, including mutation and recombination breeding; however, these methods have only produced a minor increase in productivity. Recombination and mutant breeding have recently been proposed as novel, cutting-edge approaches to overcome the limitations of conventional breeding practices. This study was conducted to assess the recurrent mutagenesis efficacy of sesame crosses, followed by the isolation and evaluation of superior breeding lines that could be released as varieties in the future. In the F4M4 generation, the populations were grown in a randomized block design (RBD), and the efficacy of recurrent mutagenesis was assessed in terms of variability parameters such as the mean, standard deviation, and coefficient of variation. During the F5M5 generation, the materials were grown in three separate trials in Compact Family Block Design to evaluate the between-family and within-family variations, followed by the isolation of improved breeding lines based on per se performance. The improved breeding lines were further advanced to the F6M6 generation for evaluation in three separate trials in an RBD. In the F6M6 generation, ANOVA, correlation, regression, path coefficient, and Mahalanobis’s D 2 analysis were computed, followed by the construction of selection indices to select superior lines. The results showed the importance of three or four EMS treatment cycles for sesame improvement in the F4M4 generation. Twenty of the top lines based on per se performance (with a selection intensity of 27%) from each category in the F5M5 generation were carried forward to the F6M6 generation. In the F6M6 generation, the top six breeding lines (with a selection intensity of 30%) from each category, for a total of 18 breeding lines, were chosen based on these index scores. These high-yielding micromutant lines could be subsequently released as varieties through multiplication trials with standard checks. After a thorough evaluation, these lines have the potential to replace the current varieties and increase production, productivity, and adoption of sesame in India
