If the liabilities are not met under the terms of the contract, the firm may default, resulting in the loss of the company. There is no clear way to distinguish between organizations that will default and those that will not prior to default. We can only make probabilistic estimations of the risk of default at best. There are two types of credit risk default models in this regard: structural and reduced form models. Structural models are used to calculate the likelihood of a company defaulting based on its assets and liabilities. If the market worth of a company's assets is less than the debt it owes, it will default. Reduced form models often assume an external cause of default, such as a Poisson jump process, which is driven by a stochastic process. They model default as a random event with no regard for the balance sheet of the company. This paper provides a Review of credit risk default models.</p> 2022-12-31T00:00:00+00:00 Copyright (c) 2022 VIDYA - A JOURNAL OF GUJARAT UNIVERSITY https://vidyajournal.org/index.php/vidya/article/view/16 ASSESSMENT OF HEAVY METALS IN SABARMATI RIVER: A CASE STUDY BEFORE AND DURING THE LOCKDOWN 2022-01-24T11:44:46+00:00 Prachi Talsania prachitalsania@gmail.com Archana Mankad aumankad@gujaratuniversity.ac.in <p>Sabarmati is one of the largest rivers in Gujarat and passes through cities like Gandhinagar and Ahmedabad. The municipal pollutants in the river comprise untreated domestic and sewage wastes. In contrast, industrial pollutants constitute the discharge of heavy metals into the river, responsible for increasing metal load in the water. Increasing heavy metal concentration in the water can cause severe problems. In this work, Cu, Mn, Fe, Cr, Zn, Pb, and Cd heavy metals were analyzed from the five selected sites for two years, 2020 and 2021, in Two seasons pre and post-monsoon. In 2020, there was a lockdown situation because of Covid-19, so all industrial the activities were shut down. Therefore pollution levels were decreased, and the environment was clean. Our study indicates that in the pre-monsoon season in&nbsp; 2020, Iron metal was highest, and in post-monsoon, Chromium was the highest. In the Post-monsoon season 2020, Iron metal was the highest, and Lead was the highest in the post-monsoon season. Because of the covid-19 lockdown, the result of post-monsoon 2020 shows the low concentration of heavy metals.</p> 2022-12-31T00:00:00+00:00 Copyright (c) 2022 VIDYA - A JOURNAL OF GUJARAT UNIVERSITY https://vidyajournal.org/index.php/vidya/article/view/24 A REVIEW ON MANGROVES AND ITS THREATS 2022-12-15T10:34:01+00:00 Juhi Gajjar juhigajjar91194@gmail.com Bhoomi Prajapati bhoomiprajapati28@gmail.com Hitesh Solanki hasolanki@gujaratuniversity.ac.in <p>Mangroves are a very important ecosystem of the earth it provides habitat for fauna and flora.

Because the demand for housing is expanding in tandem with population growth, it must be met with all available resources. The energy resources available to humanity, on the other hand, are limited and fast dwindling. In the long run, this will have a huge impact on the situation because the demand cannot be met with the available resources. As a result, resources will be depleted to a large level, causing serious problems. There are several alternatives for dealing with this scenario. Green building construction is a viable option that can be employed instead of traditional construction because it is more energy efficient. In general, the cost of constructing a green building is more than that of a conventional building, but the overall cost of the building, including upkeep, is lower. This research study focuses on the numerous facts and trends available for study about green construction, as well as the comparison between sustainable and conventional building.</em></p> 2022-12-31T00:00:00+00:00 Copyright (c) 2022 VIDYA - A JOURNAL OF GUJARAT UNIVERSITY https://vidyajournal.org/index.php/vidya/article/view/60 A REVIEW - IMPORTANCE OF PHYSICO-CHEMICAL PROPERTIES IN SOIL QUALITY 2022-03-19T04:09:46+00:00 Arzoo Patel patelarzoo2622@gmail.com Roshni Patel patel@gmail.com Bharat Maitrey bharat@gmail.com <p>The basic need of human beings for survival is food, clothes, and shelter which is completed through the medium of soil.

The practise became more important as agriculture spread, resulting in extensive deforestation that negatively impacted watersheds and biodiversity. Although they may be less prominent today, sacred groves are nonetheless important in rural Indian landscapes home to traditional people. Despite having a pan-Indian distribution, this tradition has recently attracted more attention, leading scientists to concentrate their research on India's northeast, Western Ghats, and east coast either for their global/regional significance or unique habitats. Lower life forms were badly disregarded while the majority of studies focussed on flora, primarily angiosperms, and vertebrates in the faunal studies.

(Griffiths, 1999). Stress is defined as “the non-specific response of the body to any demand for change”. (Hans Salye, 1936). Coping with stress is the process by which a person consciously attempts to master, minimize, or tolerate stressors and problems in life. Health is defined as a condition of complete bodily, mental, and social health, not only the absence of disease or disability. (WHO, 1948). The study aimed to investigate the influence of internet addiction on general health and coping stress among young adults.<strong> <em>Methods:</em></strong> The study was conducted on 120 participants between the ages of 18 to 25, out of which 60 were females and 60 were males, through purposive sampling techniques. A social demographic questionnaire, Internet Addiction Test (IAT) (Young, 1998), Brief Cope Scale (Carver, 1982) and General Health Questionnaire (Goldberg, 1972) were used to gather information. Data were analyzed by using one way ANOVA, mean, standard deviation and Pearson product moment correlation.<strong><em> Result: </em></strong>The results shows that there is a significant difference in the level of internet addiction and coping stress among young adults across their gender. there is no significant difference in the level of general health among young adults across their gender. There is no significant relationship between internet addiction and coping stress. There is no significant relationship between internet addiction and general heath.

Vitamins A, E, K, and D are fat soluble, and vitamins B1, B2, B3, B5, B6, B7, B9, B12, and C are water soluble. Micronutrients are vital components that humans and other organisms require in variable amounts throughout their lives to coordinate a variety of physiological activities and maintain good health. Essential nutrients can’t be generated in humans or can’t be synthesised in significant levels, thus they have to be received from diet. These vitamins can be found in a variety of foods, including plant and animal sources. For good health and development, they must consume a balanced diet on a regular basis.
