Analysis of maternal and foetal outcome of post-dated pregnancy in a tertiary care centre

Background: Managing pregnancy with post-dates is becoming a challenging issue due to increasing fetal morbidity and mortality. The study aimed to analyse the maternal and fetal outcomes of post-term pregnancies among Indian women, considering their earlier fetal maturation. Conducted over 18 months with 100 cases, the prospective observational study focused on pregnant mothers at or beyond 40 weeks gestational age, excluding those with certain medical complications. Methods: After obtaining approval from the ethics committee and informed consent from eligible participants, detailed histories and examinations were conducted, with close monitoring until delivery and postnatal care. Inclusive criteria encompassed singleton pregnancies with cephalic presentation, while exclusions included non-cephalic presentation, congenital anomalies, and various medical complications. Results: Revealed a predominance of primigravida women aged 20 to 35 years at 40 to 40 weeks and 6 days gestation. Spontaneous delivery occurred in 58%, with 90% delivering vaginally, while all multigravida births were vaginal post-induction. Cesarean sections were performed in 14%, primarily due to failed induction followed by fetal distress. Meconium-stained liquor was most prevalent at 42 weeks or later, correlating with higher perinatal mortality and NICU admissions in infants born beyond 42 weeks. Conclusions: Vigilant monitoring proved crucial in averting fetal jeopardy, emphasizing the importance of timely interventions to mitigate complications associated with post-term pregnancies. This study sheds light on the unique considerations and outcomes of post-dated pregnancies in the Indian population, contributing valuable insights for maternal and neonatal care in similar settings.

Nutrient dynamics in the sediments of Kerala coast

ABSTRACT Kerala is one of the smallest states in India which is situated in the south west coast of the country. Sediment samples from four prominent areas of Kerala Coast were collected and analyzed for nutrients. Variation of nutrients was highlighted according to the distributional characteristics of the designated sites. Nutrient trend in Cape, Trivandrum, Kollam was in the order as Ammonia > Nitrite >Nitrate, where as Cochin showed the trend as Ammonia > Nitrate > Nitrite. Greater concentration of ammonia in the entire sediments showed the ammonification of nitrogen compounds

Silage Characteristics of Sugarcane (\u3cem\u3eSacchrum officinarum\u3c/em\u3e) Tops in Sri Lanka

Sugarcane tops (SCTs) is generally known to be a major byproduct of sugarcane industry which is currently not utilized in a profitable manner and it is widely available at low cost particularly during the dry period in Sri Lanka when the forage are scarce for feeding of ruminants. Usually, the residue after sugarcane harvesting contains dry leaves, fresh leaves and growing point of the stalk. It increases drying of leaves in the field within 2 to 3 days after harvesting due to dry weather conditions prevailing in the harvesting period and much of the tops are burned and wasted in the field. Therefore, it is difficult to use tops as feed unless they are preserved. Silage making is a good preservation technique which can be used under this condition. Therefore, the objective of this study was to compare the ensiling characteristics and nutritive value of SCTs or Guinea (Panicum maximum) ‘A’ grass with different additives

Fine Selmer Groups and Isogeny Invariance

We investigate fine Selmer groups for elliptic curves and for Galois representations over a number field. More specifically, we discuss Conjecture A, which states that the fine Selmer group of an elliptic curve over the cyclotomic extension is a finitely generated $\mathbb{Z}_p$-module. The relationship between this conjecture and Iwasawa's classical $\mu=0$ conjecture is clarified. We also present some partial results towards the question whether Conjecture A is invariant under isogenies.Comment: 20 page

Bubbling and bistability in two parameter discrete systems

We present a graphical analysis of the mechanisms underlying the occurrences of bubbling sequences and bistability regions in the bifurcation scenario of a special class of one dimensional two parameter maps. The main result of the analysis is that whether it is bubbling or bistability is decided by the sign of the third derivative at the inflection point of the map function.Comment: LaTeX v2.09, 14 pages with 4 PNG figure

Selection of accessions from minicore to improve disease resistance in groundnut

A mini core subset of world germplasm comprising 188 accessions was evaluated for late leaf spot, rust and seed colonization by A. flavus. Accessions highly resistant to late leaf spot (ICG 2857, ICG 8760, ICG 12625, ICG 13787, ICG 12672, ICG 14475 and ICG 11426), rust (ICG 4746, ICG 6706, ICG 11088 and ICG 11426) and A. flavus (ICG 14985, ICG 6025, ICG 3673, ICG 12625, ICG 13787 and ICG 8760) were identified. Some accessions (ICG 12625, ICG 13787, ICG 11426 and ICG 8760) combined resistance to at least two diseases. The identified accessions along with three popular cultivars (GPBD 4, TAG 24 and JL 24) were subjected to RAPD assay using twenty primers to assess molecular diversity. The genetic similarity (Sij) ranged from 0.64 to 0.92. Accessions ICG 6706, 14475 and 8760 were more diverse with the popular varieties. The information generated in this study will be of great value to plant breeders in their effort to develop varieties resistant to fungal diseases through hybridization

A social licence for science: capturing the public or co-constructing research?

The “social licence to operate” has been invoked in science policy discussions including the 2007 Universal Ethical Code for scientists issued by the UK Government Office for Science. Drawing from sociological research on social licence and STS interventions in science policy, the authors explore the relevance of expectations of a social licence for scientific research and scientific contributions to public decision-making, and what might be involved in seeking to create one. The process of seeking a social licence is not the same as trying to create public or community acceptance for a project whose boundaries and aims have already been fully defined prior to engagement. Such attempts to “capture” the public might be successful from time to time but their legitimacy is open to question especially where their engagement with alternative research futures is “thin”. Contrasting a national dialogue on stem cells with the early history of research into bioenergy, we argue that social licence activities need to be open to a “thicker” engagement with the social. Co-constructing a licence suggests a reciprocal relationship between the social and the scientific with obligations for public and private institutions that shape and are shaped by science, rather than just science alone

Improved control strategy of DFIG-based wind turbines using direct torque and direct power control techniques

This paper presents different control strategies for a variable-speed wind energy conversion system (WECS), based on a doubly fed induction generator. Direct Torque Control (DTC) with Space-Vector Modulation is used on the rotor side converter. This control method is known to reduce the fluctuations of the torque and flux at low speeds in contrast to the classical DTC, where the frequency of switching is uncontrollable. The reference for torque is obtained from the maximum power point tracking technique of the wind turbine. For the grid-side converter, a fuzzy direct power control is proposed for the control of the instantaneous active and reactive power. Simulation results of the WECS are presented to compare the performance of the proposed and classical control approaches.Peer reviewedFinal Accepted Versio

Family Planning Decisions, Perceptions and Gender Dynamics among Couples in Mwanza, Tanzania: A Qualitative Study.

Contraceptive use is low in developing countries which are still largely driven by male dominated culture and patriarchal values. This study explored family planning (FP) decisions, perceptions and gender dynamics among couples in Mwanza region of Tanzania. Twelve focus group discussions and six in-depth interviews were used to collect information from married or cohabiting males and females aged 18-49. The participants were purposively selected. Qualitative methods were used to explore family planning decisions, perceptions and gender dynamics among couples. A guide with questions related to family planning perceptions, decisions and gender dynamics was used. The discussions and interviews were tape-recorded, transcribed verbatim and analyzed manually and subjected to content analysis. Four themes emerged during the study. First, "risks and costs" which refer to the side effects of FP methods and the treatment of side -effects as well as the costs inherit in being labeled as an unfaithful spouse. Second, "male involvement" as men showed little interest in participating in family planning issues. However, the same men were mentioned as key decision-makers even on the number of children a couple should have and the child spacing of these children. Third, "gender relations and communication" as participants indicated that few women participated in decision-making on family planning and the number of children to have. Fourth, "urban-rural differences", life in rural favoring having more children than urban areas therefore, the value of children depended on the place of residence. Family Planning programs should adapt the promotion of communication as well as joint decision-making on FP among couples as a strategy aimed at enhancing FP use
