Udalguri College, established on 20 August 1978, is a general degree college in Udalguri, Assam, India. This college is affiliated with the Gauhati University and Bodoland University. This college offers different courses in arts and science.It also has distance learning centers of IGNOU and IDOL.History:Udalguri College came into existence on the 20th August 1979, as a result of the ceaseless and untiring efforts of the preparatory committee under the leadership of the founder Principal Late Sailendra Nath Brahma. The primary aim was to provide an opportunity to the economically weak and underprivileged people of this region. The college has been rendering valuable service to the cause of imparting higher education in Udalguri, its outskirts and nearby districts too from the last 41 years. During its journey, it has created opportunities for the underprivileged and the youths from the weaker sections of society, giving them a sense of purpose and direction in the pursuit of their dreams. Starting as an Arts college in 1979, the college has now grown into a full-fledged two-stream college with Arts and Science, and Honours courses in almost all the subjects offered.Accreditation:NAAC inspected the college in 2004 for the first Cycle of Accreditation, had graded the college with C++ (68.25%) and the second cycle of accreditation was carried out in 2016 and awarded ‘B’ grade (CGPA2.05).Courses:Courses in BA and MA are available across Humanities and Science streams..
In this paper, we have presented bulk viscous cosmological models in modified gravity theory, where the gravitational action contains a general function of f(G) gravity, where G denotes the Gauss-Bonnet invariant in the framework of Bianchi type III cosmological space-time. We obtain cosmological solutions, especially for a particular choice f(G) = beta Gm1+ eta Gm2, where beta, eta, m1 and m2 are arbitrary constants, and the solution of f(G) exhibits that the model is initially stable for redshift 'z'. Later, it presents the model's instability in the present and future. The variation of the deceleration parameter with respect to redshift indicates a transitioning universe for the respective model. Furthermore, we also examine the energy conditions and the statefinder parameter r - s, and r - q plane for the bulk viscous cosmological model within the f(G) theory of gravity. The physical and geometrical properties of the model are also discussed.
Contracting cancer typically induces a state of terror among the individuals who are affected. Exploring how chemotherapy and anxiety work together to affect the speed at which cancer cells multiply and the immune system’s response model is necessary to come up with ways to stop the spread of cancer. This paper proposes a mathematical model to investigate the impact of psychological scare and chemotherapy on the interaction of cancer and immunity. The proposed model is accurately described. The focus of the model’s dynamic analysis is to identify the potential equilibrium locations. According to the analysis, it is possible to establish three equilibrium positions. The stability analysis reveals that all equilibrium points consistently exhibit stability under the defined conditions. The bifurcations occurring at the equilibrium sites are derived. Specifically, we obtained transcritical, pitchfork, and saddle-node bifurcation. Numerical simulations are employed to validate the theoretical study and ascertain the minimum therapy dosage necessary for eradicating cancer in the presence of psychological distress, thereby mitigating harm to patients. Fear could be a significant contributor to the spread of tumors and weakness of immune functionality.
This study addresses a modified mathematical model of tumor growth with targeted chemotherapy consisting of effector cells, tumor cells, and normal cells. To investigate the dynamics of the model, local and global stability analyses have been performed at the equilibrium points of the model. It is found that the tumor-free steady state is globally asymptotically stable under certain conditions, which suggests that the prescribed treatment can eradicate tumor cells from the body for a threshold value of tumor growth rate. The main result of this study is that if the tumor growth rate is tiny, it is possible to eradicate the tumor from the body using a smaller amount of targeted chemotherapy drugs with less harm to the other healthy cells. If not, it requires a high dose of targeted chemotherapy drugs, which can increase the side effects of the drugs. Numerical simulations have been performed to verify our analytical results.
Mustura subhashi, new species, is described from the Dikal River, a north bank tributary of the Brahmaputra drainage in Arunachal Pradesh. It is distinguished from all its congeners by having a colour pattern of 14-23 dark-greyish black to dark brown irregular bars on a greyish to pale beige body; pre-dorsal bars thin, numerous, wider than interspaces, weakly contrasted, uniting dorsally at lateral one-third or midway on flank to form thicker bars, coalescing further at lateral one-fifth and continuous on dorsum with contralateral bars; bars below dorsal fin exhibiting similar condition but slightly wider than pre-dorsal bars; post-dorsal bars thicker than anterior bars, wider than interspaces, sharply contrasted, rarely coalescing on flank; and a short bar along the caudal mid-line, rarely forming a blotch. Based on re-examination of the type specimens and additional materials, Mustura dikrongensis is confirmed as a species belonging to Mustura, and M. harkishorei is not sufficiently diagnosed from 'Nemacheilus' corica.
Exploratory surveys were conducted along the Kameng River, a northern tributary of the Brahmaputra River, northeast India, to assess the fish diversity and its distribution pattern, abundance and habitat status. A total of 117 fish species were recorded from 12 selected sites of the river basin. Cyprinids represented the dominant group with 45 species. Garra annandalei, G. quadratirostris, Neolissochilus hexagonolepis and Schizothorax richardsonii were the most dominant species. Principal component analysis revealed the importance of pH, dissolved oxygen, water temperature and turbidity in shaping the fish species assemblage. The diversity indices and catch per unit effort (CPUE) showed significant variation at different sites in different seasons. Based on NMDS analysis of altitude and species composition, the river is put under three different zones: upper (u), middle (m) and lower (l). Major potential threats for the riverine ecology and their conservation management strategies have been discussed. The present study will be useful for conservation, planning and management of the Kameng River ecosystem and also provide baseline data to future assessments.
