The effect of organic pollution and eutrophication of the Ain Zada dam water on fish, Bordj Bou Arreridj-Setif, Algeria
The objective of this study is to demonstrate the impact of pollution on the fish population in the Ain Zada Dam, where the quantity of fish has experienced a dramatic decline, dropping from 118,139 kg in 2010 to only 7,578 kg in 2022, with a concerning low of 6,335 kg recorded in 2018. The main causes of this pollution are contamination by organic materials, including nitrates, nitrites, phosphates, and ammonium, which serve as nutrients for plankton and plants. This leads to their dense growth and proliferation in the reservoir and on the water surface. They consume oxygen and block light from reaching the reservoir’s waters, reducing oxygen production by the plants within the reservoir. This results in an accumulation of organic matter, a phenomenon known as eutrophication. The COD (Chemical Oxygen Demand) of 84.6 mg/l and the BOD5 (Biochemical Oxygen Demand over 5 days) of 6 mg/l recorded in 2022 confirm a drastic reduction in oxygen levels, with a recorded value of 7.6 mg/l in 2022. These levels fall below the permissible thresholds of 7 mg/l in summer and 10 mg/l in winter, highlighting the urgent need for intervention to address this situation..
A CRITICAL ANALYSIS OF THE PSYCHOLOGICAL NUANCES OF SISTERLY BONDS AND IMMIGRANT EXPERIENCES IN DIVAKARUNI'S DIASPORA LITERATURE
In the genre of diasporic literature, Chitra Banerjee Divakaruni's novels stand out as vibrant masterpieces that combine the experiences of immigrant women through the perspective of sisterhood. This work analyses the psychological nuances of Divakaruni's characters and explores how sisterhood represents the immigrant reality. This study aims at how sisterhood is presented in Divakaruni's extraordinary novels, centering on the psychological stresses and achievements characterizing the characters' lived experiences. Through close textual analysis of "The Mistress of Spices," "Sister of My Heart," "Oleander Girl," and "Queen of Dreams," this research employs feminist and postcolonial theories to analyze complexities of sisterly roles and relations within diaspora cultures. From the narratives of Divakaruni, it is evident that sisterhood is a complex interaction that can be supportive, empowering, and conflicting. The main characters lead their families through the dilemmas of cultural conservation and adjustment to new conditions; their sisterly bonds help perpetuate preexisting traditions and stimulate the transformation process. The study explains how Divakaruni employs the theme of sisterhood to represent the situation of immigrant women of color in redefining their cultural identities in the new environment. This study is helpful in the ongoing discussions about the diaspora literature, and its findings reveal how the relationship between sisters can help improve our understanding of how immigrants navigate cultural change and individually develop an identity. The issues of sister relationships in Divakaruni's works come out clearly and contribute to conveying the Indian immigrants and the circumstances they undergo as they seek to build their new homes abroad and ask questions about their identity..
Analysis and Testing of a High Ground Clearance Suspended Intermediate Strip Lay Cutting and Tanning Machine
Aiming at the low chassis of the conventional cutter-sunner, the lateral spreading structure of the vertical cutting table leads to the difficulties in side-row harvest, the poor quality of cutter-sunner spreading, and the poor pass-through performance of the machine and other problems. The design of a high ground clearance suspended cutter-sun machine, the use of the middle laying form, the transmission system using hydraulic motor drive. The whole machine structure is mainly composed of a frame, transmission device, suspension device, reciprocating cutter, screw conveyor roller, grain separator and hydraulic system. Kinematics, dynamics and finite simulation analysis were conducted for the suspension mechanism of the sun cutter, and the results show that the designed suspension structure can meet the requirements in field operation. Taking the coefficient of variation of spreading width and the coefficient of spreading uniformity as the indexes, the forward speed of the unit and the rotational speed of the main drive shaft as the influencing factors, orthogonal tests were conducted, and through the establishment of the regression equation model, the optimal working state of the cutter-sunburner was acheived obtained when the forward speed of the unit was 1.028m/s and the rotational speed of the main drive shaft was 430.042r/min. After several tests, the coefficient of variation of spreading width is 5.897% on average, and the coefficient of spreading uniformity is 104.251% on average. The results show that the cutter-sun dryer can complete the cutting and laying operation at one time under normal working condition, with neat stubble cutting, smooth conveying and orderly laying, which can meet the requirements of subsequent drying , picking and threshing operations.
REVIVING HOPE FROM SORROW: BHAGAT'S EXPLORATION OF INTERNAL GROWTH
In the field of literature, the contemporary Indian author Chetan Bhagat, with his entrancing storytelling capabilities, has made an undisputed name for himself. The article explores the themes of bereavement, personal development, and optimism in his novels namely “One Night at the Call Centre," “The 3 Mistakes of My Life," “2 States," and “Half Girlfriend.” In Bhagat’s work, loss does two things: it unites the feelings of individual bereavement and collective calamity while acting as a catalyst for the development of characters. The characters have broken relationships and wasted dreams and come to major decisions that significantly change their lives. Internal growth is a recurring motif that emerges when one succeeds in fighting with problems, reflecting on them, and discovering their attitudes towards others. The perspicuity and resourcefulness of Bhagat’s characters are highlighted. The theme of hope, universally present from the dawn of time to its sunset, has characters pursue their aspirations and overcome obstacles that come their way. Bhagat employs hope as a strategic tool for addressing problems and surrendering a positive future to readers. Such themes are representative of Bhagat’s perspective, which is characterized by an understanding of the elements that hinder and those that inspire young Indians. The reader can feel a very strong emotion reading the author’s work, and that emotion stems from something that the reader has previously experienced, and in doing so, it will offer them comfort and motivation. Through analyzing Chetan Bhagat’s work, one can understand the significance of this writer in contemporary Indian writing, which is attributable to his capacity to integrate commercial and literary fiction. Through his works, he captures the essence of the modern Indian way of living, resulting in debates on personal growth and courage. Bhagat’s art is the living manifestation of India's complex identity within the context of globalization. In the end, Bhagat’s writings are a dedication to the firm resolve of the human spirit in times of grief, the human potential to grow from within, and how optimism plays a role in personal growth. The universal themes of the novels are helpful to readers at all levels globally, resulting in his novels being relatable and relevant to the world. Wherever a reader is and however afflicted he may be, there lies his peace, his guide out of the wilderness, and his sure possessor.
Inter and Intraspecific Hybridization for Higher Yield, Improved Fruit Quality and ToLCV Tolerance in Tomato (Solanum lycopersicum L.)
The present experiment was conducted in line × tester mating design including wild species Solanum peruvianum to estimate heterosis over better parent for 23 yield and quality characters. F1 showing high specific combining ability (SCA) for yield, whereas high general combining ability (GCA) was observed for number of fruits per plant, fruit weight and polar diameter of fruits. Two promising hybrids H-86 × S. peruvianum and LA-3948 × Pusa Rohini were selected on the basis of their per se performance. Heterosis and SCA effects were relevant since they can be used commercially for high yield, better quality traits, low percent disease index (PDI) and tomato leaf curl disease (ToLCV) incidence. Predominance of additive gene action were evident for regulating the characters like days to 50% flowering and PDI. Both additive and non-additive gene action were important for polar fruit diameter, pericarp thickness and fruit acidity, whereas fruit weight, number of fruits per plant, number of locules per fruit, total soluble solids (TSS) and fruit yield per plant were governed by non-additive gene action.
