WATER QUALITY PREDICTION USING SUPPORT VECTOR MACHINE IN WIRELESS SENSOR NETWORKS
In Aquaculture, the yields of the aquatic organism depend on the quality of water. To collect the data from the pond like temperature, dissolved oxygen, pH level, turbidity, carbon dioxide the sensors are placed inside the pond. The detection of water quality can be done using the data classification algorithms. In this project, we have proposed a Support Vector Machine (SVM) classifier to predict the quality of water in wireless sensor networks. The sensor nodes are placed in the pond. Here cluster head based routing protocol is used based on the fractional calculus artificial bee colony algorithm, in which the individual decision trees are merged along the routing path. Then, the results of cluster head-based routing protocol are sent to sink node, in which the proposed SVM classifier is used to classify the water quality parameter. From the results, we proved that, the proposed algorithm achieves the better prediction accuracy as 85%
The impact of COVID-19 lockdown on postpartum mothers in London, England: An online focus group study
Aims
This study examines the impact of COVID-19 lockdown on postpartum mothers in England, with the aim of identifying opportunities to improve maternal experience and wellbeing. The postpartum/postnatal period is widely acknowledged as a time when mothers require greater levels of support from multiple sources. However, stay-at-home orders, commonly known as âlockdown,â deployed in some countries to limit COVID-19 transmission reduced access to support. In England, many postpartum mothers navigated household isolation within an intensive mothering and expert parenting culture. Examining the impact of lockdown may reveal strengths and weaknesses in current policy and practice.
Subject and methods
We conducted online focus groups involving 20 mothers living in London, England, with âlockdown babies,â following up on our earlier online survey on social support and maternal wellbeing. We thematically analysed focus group transcripts, and identified key themes around Lockdown Experience and Determinants of Lockdown Experience.
Results
Participants raised some positives of lockdown, including fostering connections and protection from external expectations, but also raised many negatives, including social isolation, institutional abandonment, and intense relationships within the household. Potential reasons behind variations in lockdown experience include physical environments, timing of birth, and number of children. Our findings reflect how current systems may be âtrappingâ some families into the male-breadwinner/female-caregiver family model, while intensive mothering and expert parenting culture may be increasing maternal stress and undermining responsive mothering.
Conclusions
Facilitating partners to stay at home during the postpartum period (e.g., increasing paternity leave and flexible working) and establishing peer/community support to decentre reliance on professional parenting experts may promote positive postpartum maternal experience and wellbeing
Cone bean computed tomographic evaluation, localization and surgical management of Non-syndromic Inverted mesiodens in close proximity to nasal floor: Case report and review of literature
Supernumerary teeth are numerical developmental anomaly defined as an additional teeth present as a complement to the normal dentition. Mesiodens is relatively a most common anomaly in the developing dentition stages. This article presents the case report of a 6-year old girl child who with the chief complaint of malaligned upper front teeth. On detailed clinical and radiographic examination the presence of vertically impacted mesiodens in the anterior region with close proximity to nasal floor was noted. The child didnât have any relevant medical or dental history. Due to pertaining complexity and its close proximation to the nasal floor it was decided to carryout extraction of mesiodens under general anesthesia. Following the extraction of mesiodens under general anesthesia after the scheduled recovery appropriate post-operative instructions were given to the child and their parents and the child was discharged. Follow up was scheduled after 1 week which showed uneventful healing of the surgical site and subsequent eruption of maxillary right lateral incisor. Mesiodens belong to the category of supernumerary teeth which can result numerous dentofacial defects if not removed promptly. Hence parents must have considerable attention and seek dental help whenever they notice an asymmetric pattern of teeth eruption in their children. In this case scenario the mesiodens were removed as it prevented the eruption of successor permanent teeth which henceforth resulted with considerable esthetic concerns for the child due to its prolonged retention within the dental arch
Menstrual product choice and the extent of period poverty among young adult females: findings from a cross-sectional study in Kerala, India
Background: In Kerala state, India, while there is higher coverage of hygienic methods for menstrual protection among young women, empirical evidence on menstrual hygiene management is limited. This study aims to present menstrual hygiene product choices and the extent of period poverty among young adult females in Kerala.
Methods: A cross-sectional study was conducted in Kerala using a web-based Google form. Data were collected on menstrual product usage, perceptions and attitudes towards menstruation, awareness and use of government initiatives for menstrual hygiene management, perspectives on better management, period poverty, and associated factors.
Results: The mean age of respondents was 21.7 years (SD±2.0). Cultural beliefs hindered the choice of menstrual products. Period poverty was reported by 25.5% of respondents, with higher rates among younger, lower social category, and unemployed individuals. Lower income and negative attitudes towards menstruation were significantly associated with higher period poverty.
Conclusions: There is a need for free menstrual products for the financially disadvantaged. Further research is necessary to gain a comprehensive understanding of period poverty in this community
DEVELOPMENT AND VALIDATION OF STABILITY-INDICATING RP-UPLC METHOD FOR THE SIMULTANEOUS ESTIMATION OF TEZACAFTOR AND IVACAFTOR IN FORMULATIONS
Objective: Aim of the present research work was to develop a sensitive, rapid and accurate, stability-indicating RP-UPLC method for the simultaneous estimation of tezacaftor and ivacaftor in formulations.
Methods: The chromatographic separation of the mixture of tezacaftor and ivacaftor was attained in isocratic method utilizing a mobile phase of 0.1 % orthophosphoric acid and acetonitrile in the proportion of 50:50%v/v utilizing a HSS C18 column which has dimensions of 100Ă2.1 mm, 1.7 m particle size and the flow rate of 0.3 ml/min. The detection system was monitored at 292 nm wavelength maximum with 1.5 ml injection volume. The present method was validated as per the guidelines given by the ICH for specificity, accuracy, sensitivity, linearity and precision.
Results: The retaining time for tezacaftor and ivacaftor were achieved at 1.071 min and 0.530 min, respectively. Tezacaftor, ivacaftor and their combined drug formulation were exposed to thermal, acidic, oxidative, photolytic, and alkaline conditions. The developed method was highly sensitive, rapid, precise and accurate than the earlier reported methods. The total run time was decreased to 2.0 min; hence, the technique was more precise and economical. Stability studies directed for the suitability of the technique for degradation studies of tezacaftor and ivacaftor.
Conclusion: The projected method can be utilized for routine analysis in the quality control department in pharmaceutical trades

The India Face Set: International and Cultural Boundaries Impact Face Impressions and Perceptions of Category Membership
This paper serves three specific goals. First, it reports the development of an Indian Asian face set, to serve as a free resource for psychological research. Second, it examines whether the use of pre-tested U.S.-specific norms for stimulus selection or weighting may introduce experimental confounds in studies involving non-U.S. face stimuli and/or non-U.S. participants. Specifically, it examines whether subjective impressions of the face stimuli are culturally dependent, and the extent to which these impressions reflect social stereotypes and ingroup favoritism. Third, the paper investigates whether differences in face familiarity impact accuracy in identifying face ethnicity. To this end, face images drawn from volunteers in India as well as a subset of Caucasian face images from the Chicago Face Database were presented to Indian and U.S. participants, and rated on a range of measures, such as perceived attractiveness, warmth, and social status. Results show significant differences in the overall valence of ratings of ingroup and outgroup faces. In addition, the impression ratings show minor differentiation along two basic stereotype dimensions, competence and trustworthiness, but not warmth. We also find participants to show significantly greater accuracy in correctly identifying the ethnicity of ingroup faces, relative to outgroup faces. This effect is found to be mediated by ingroup-outgroup differences in perceived group typicality of the target faces. Implications for research on intergroup relations in a cross-cultural context are discussed.

BRINE SHRIMP LETHALITY BIOASSAY OF BOUGAINVILLEA GLABRA
The crude methanolic extract of Bougainvillea glabra leaves has been investigated for the evaluation of the cytotoxic activity. All the extracts of the plant were screened for their cytotoxicity by using brine shrimp nauplii (Artemia salina) lethality bioassay. The toxicity was assessed in terms of LC50 (lethality concentration), 10 nauplii were taken into three replicates of each concentration of the methanolic leaf extract. Brine shrimps were checked for the mortality during 24 hrs period, surviving brine shrimps were counted and LC50 was evaluated. The results showed that all the extracts were showing potent toxicity to the nauplii. The LC50 values were compared to the standard potassium dichromate. It indicates that the extracts are toxic even at low doses. Further investigation is needed to study the acute and subacute toxicity of the extracts for its safe application to the humans. Keywords: Artemia salina, cytotoxicity, Bougainvillea glabra, mortalit
Household, community, sub-national and country-level predictors of primary cooking fuel switching in nine countries from the PURE study
Introduction. Switchingfrom polluting (e.g. wood, crop waste, coal)to clean (e.g. gas, electricity) cooking
fuels can reduce household air pollution exposures and climate-forcing emissions.While studies have
evaluated specific interventions and assessed fuel-switching in repeated cross-sectional surveys, the role
of different multilevel factors in household fuel switching, outside of interventions and across diverse
community settings, is not well understood. Methods.We examined longitudinal survey data from
24 172 households in 177 rural communities across nine countries within the Prospective Urban and
Rural Epidemiology study.We assessed household-level primary cooking fuel switching during a
median of 10 years offollow up (âŒ2005â2015).We used hierarchical logistic regression models to
examine the relative importance of household, community, sub-national and national-level factors
contributing to primary fuel switching. Results. One-half of study households(12 369)reported
changing their primary cookingfuels between baseline andfollow up surveys. Of these, 61% (7582)
switchedfrom polluting (wood, dung, agricultural waste, charcoal, coal, kerosene)to clean (gas,
electricity)fuels, 26% (3109)switched between different polluting fuels, 10% (1164)switched from clean
to polluting fuels and 3% (522)switched between different clean fuels
Nations within a nation: variations in epidemiological transition across the states of India, 1990â2016 in the Global Burden of Disease Study
18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016
