Mathematical Study on Prey-Predator Dynamics Under Effect of Water Contamination
Authors: Tangri Shreya , Kumari Ruby , Kalra Preety
Published: January 2024

A significant class of water pollutants emerging as a threat to human and aquaticpopulations is Per-and-polyfluoroalkyl substances (PFAS). The primary concern linked to PFAS is that they exhibit bioaccumulation potential as their perfluorocarbon moieties do not break down or do so very slowly under natural conditions, which is why PFAS has often been termed “forever chemicals.” These chemicals are disposed off in aquatic bodies via improper disposal methods, and because PFAS are persistent, they accumulate or concentrate in the water environment. Subsequently, these chemicals hamper the aquatic population and further enter the human food chain via direct consumption of affected aquatic species and drinking water. In this study, a mathematical model has been developed to understand the alarming consequences of PFAS on human and aquatic populations and the various challenges being faced due to inadequate treatment and management of these chemicals. The model has been analyzed for stability at the equilibrium points. Numerical simulations have also been carried out to support the analytical findings. The analysis demonstrates that rising PFAS contamination is extremely hazardous to both aquatic and human populations and immediate control methods need to be devised to restrain their increasing levels in water.

Impact of Mother Attachment on the Psychological Immunity among girl students studying at Senior Secondary level
Authors: Guha Sampurna , Beri Nimisha
Published: January 2024

Attachment can be understood as a long-lasting, deep and strong emotional bond formed between the primary caregiver (mother) and the child or infant, especially during early formative years which arises out of the human need to connect and seek affection, love, and security. It is seen that early attachment experiences impact our behaviour and relationships as adults. Mother-daughter attachment is a unique form of attachment which is studied under the Mother-Daughter Attachment Model helping us to explore and understand the attachment needs of the mother-daughter relationship across ages, cultures, and areas. The current study does not focus on the intergenerational attachment between mothers and girls, rather it tries to study the impact of gender as an independent variable on mother attachment and psychological immunity of 2160 adolescents (n1 (boys) = 1080; n2 (girls) = 1080) studying in senior secondary classes (class XI) of government and private schools in Delhi NCR. It also aims to investigate the impact of mother attachment as an independent variable on the Psychological Immunity (PI) of adolescents and among girls specifically, using linear regression analysis. It is seen that gender plays no significant role in influencing mother attachment, though girls are reported to demonstrate lesser externalizing behaviours than boys in case of avoidant or insecure attachments; however, mother attachment plays a significant role in impacting PI of students in the transition phase from childhood to adulthood. The study reveals how coping behaviours, daily stress management, and the mental well-being of adolescents are closely linked to maternal attachment, though mother attachment is not found to significantly impact the PI of girl students in particular. The need for mental health professionals to better understand the intricacies of mother-daughter relationships thereby helping to foster the need to support availability of better guidance and counselling services, healthier aging among mothers, better mental health and emotional well-being of girls and women is recommended.

Published: January 2024

W.B. Yeats stands out as one of the most influential poets of the twentieth century. His symbolic poetry and his political and philosophical ideas are all prominently reflected in his work. During his lifetime, he was deeply influenced by a few remarkable women who made significant contributions to his poetic development and played a pivotal role in shaping his personality. Yeats's poems chosen for this study offer a profound insight into the predicament of women within various socio-cultural and economic contexts. This analysis will explore how Yeats projected female voices through multiple images and symbols in poems such as 'A Prayer for My Daughter,' 'Among School Children,' and 'Leda and the Swan.' While Maud Gonne is widely recognized as a central figure in Yeats's love poems, it's essential to acknowledge that she wasn't the sole woman who influenced the artist's evolution. Others, like Lady Gregory, Olivia Shakespeare, and George Hyde-Lees, the wife of W.B. Yeats, played significant roles in the later phase of his life, particularly in developing his philosophical treatise, "A Vision." In his final poems, Yeats attempted to convey his ultimate understanding of love, emphasizing its perfection in the unbroken relationship between the body and the mind. Works like 'Among School Children,' 'Leda and the Swan,' 'The Second Coming,' 'Sailing to Byzantium,' 'A Man Young and Old,' and many other universally acclaimed poems were inspired by his complex relationships with Maud Gonne and others.

Published: January 2024

Ocean waves play a crucial role in influencing a wide range of marine and fisheries activities. In this research study, we aim to analyze the climatological conditions of sea wave heights in Sumatran waters over a span of 83 years (1940-2022). We utilize three-dimensional Copernicus numerical model simulations to examine seasonal patterns of sea wave heights and assess the likelihood of extreme wave events. Our findings reveal that high waves, reaching heights of 4-5 meters, are predominantly observed in the western and southern zones off the coast of Sumatra, particularly in the vicinity of smaller islands. Conversely, in enclosed or semi-enclosed waters, such as the lee side of Sumatra and the Malacca Strait, sea wave heights tend to be relatively lower. Seasonally, our study indicates that extreme wave heights are more likely to occur during the west season as opposed to the east season. This research provides valuable insights into the dynamic ocean wave conditions in Sumatran waters, which can have significant implications for various sectors reliant on the ocean environment.

This research aims to analyze morphometrics of (P. penicillatus) and (P. versicolor) in waters of Sabang. A total of 50 samples from each species of P. penicillatus and P. versicolor were used for morphometric analysis using Traditional Morphometric and Truss Morphometric approaches. Morphological analysis indicated that both lobster species are categorized into two distinct groups. Traditional morphometric character testing using ANOVA showed that species differences significantly influence the variation in morphological characters (P<0.05) in both lobsters. Further Duncan post hoc tests revealed that four characters (HL), (CHW), and (CHL)) differed significantly between the species. P. penicillatus shared three characters similar to P. versicolor, namely (HL), (CHW), and (CHL). This similarity is based on the shape of HL, CHW, and CHL in both lobsters. In the Truss Morphometric character testing with ANOVA, it was found that species differences affect the characters significantly (P<0.05). The Duncan post hoc test revealed that five characters ([A1, A3], [B1, B3], [C5, C6], D4, [D5, D6]) differed significantly between species. DFA resulted in 1 function, with an eigenvalue of 27.595, indicating that it explains 100% of the total variance. The morphological characters that significantly contribute to the differentiation between species are A1, B1, C5, A5, and D5.

The achievement of technical and economic efficiency is one indicator in assessing the fishing process's capability. The purpose of this study was to formulate production factors of drift gillnets at The Kuala Tadu and The Kuala Tuha fishing base and to calculate the technical and economic efficiency of the use of production factors for drift gillnets at both locations. Production factors that support the success of drift gillnets operation are net depth, net length, boat size, amount of fuel, trip duration, mesh size, and engine power analyzed using the Cobb-Douglas approach. The results showed that the equation of production function for drift gillnet is LnY = 3.110 +0.112 LnX2 + 0.191 LnX3 + 0.105 LnX4 + 0.251 LnX6 with a value of R2 is 0.833. The technical efficiency study of 20 units of drift gillnets showed that the value of production elasticity (EP) for using production factors for net length (0.112), vessel size (0.191), amount of fuel (0.105), and mesh size (0.251) was < 1. It means that the use of factors of production is no longer efficient. The economic efficiency of using the variable production factors of drift gillnets is no longer efficient because the value of NPMxi/BKMxi >1.

L’objectif de l’étude est de réduire les risques de dissémination du Fusarium oxysporum fs albedenis (bayoud) et d’incendies de palmeraies, causés par l’accumulation des sous-produits du palmier dattier. Pour cela, nous avons réalisé des entretiens avec les phœniciculteurs des oasis et de leurs extensions sur l’entretien du palmier dattier, la gestion de ses résidus, les problèmes engendrés par leur accumulation, ainsi que sur les voies de pérennisation des opérations de nettoyage des palmeraies. Nous avons également évalué le poids des différents types de résidus du palmier dattier et exploité les données sur les incendies. L’étude a montré que les fumures apportées au palmier dattier sont faibles et que l’accumulation des sous-produits provoque la dissémination de maladies cryptogamiques (Fusarium), la prolifération de ravageurs (cochenille blanche), un encombrement et le déclenchement d’incendies. Elle a également montré qu’un palmier produit annuellement 0,62 kg de fibrillium, 15 palmes sèches, 10 rafles et 7 pétioles, qui pèsent respectivement 0,91 kg/palme, 0,39 kg/rafle et 0,43 kg/pétiole, soit en moyenne 21,2 kg/an de résidus par palmier. Le potentiel de biomasse produite par la culture du palmier dattier au Tafilalet s’élève donc à 52 400 tonnes/an, dont près de 62 % sont laissés sur le sol, à l’extérieur des parcelles ou brulés. Les entretiens ont montré que la valorisation de ce flux régulier de biomasse serait bénéfique pour la population oasienne et la filière phœnicicole. Les projets de valorisation intégrant les producteurs auront probablement un effet d’entraînement sur l’élagage des palmiers et le nettoyage des palmeraies. Ils contribueront également à atténuer la dissémination du bayoud et la fréquence des incendies, et par conséquent à la durabilité des oasis.

Large expanses of green, open land are frequently converted as a result of population growth and quick development. This phenomenon causes the decreasing of water infiltration area which has an impact on increasing runoff coefficient. In the urban drainage problem, paving blocks are often used as road pavement construction materials to reduce surface runoff. The aim of this research is to study the characteristic of flow in the paving block made from plastic waste material. The research conducted in the laboratory testing utilizing a rainfall simulator by several variations in slope of 0% to 15%. The findings indicate that paving blocks made from plastic waste have less runoff coefficient than asphalt and/or concrete pavement. There is a correlation between the slope of the land and the runoff coefficient value which the runoff coefficient value increasing as the slope of the land increases. That finding is then applied in urban drainage problem located in the Cipamokolan Village region in Bandung City with the help of SWMM program for drainage calculation. As a result, the runoff discharge is decreasing by implementing the paving block made from plastic waste.
