Fungal mycotoxins are the secondary metabolities and are harmful to plants, animals, and humans. Common aflatoxins are present and isolated from feeds and food comprises aflatoxins B1, B2, G1, and G2. Public health threats or risk of foodborne disease posed by mycotoxins, especially the export or import of such meat products are of primary concern. This study aims to determine the concentration of the level of aflatoxins B1, B2, G1, G2 M1, and M2 respectively in imported burger meat.
Floods are one of the most extreme events that affect human life in different regions worldwide. In India, North Bihar is one of the regions affected by floods every year during the monsoon season. Every year, floods cause the loss of human and cattle lives. It has also become the reason for enormous economic loss. Damage to infrastructure is a significant cause of such economic loss. Every year, transportation infrastructure gets inundated due to damage to the pavement during severe flood conditions. Many researchers have investigated the impact of floods on pavement structures. They have reported the different factors significantly influencing the pavement during flood conditions. Different forms of pavement failure take place due to this. Pavement deterioration models were developed to predict pavement damage. None of the deterioration models are suitable for all regions. The suitability of deterioration models depends upon conditions in the selected region. In this study, the impact of floods on the pavement in North Bihar is investigated. The different forms of pavement failure were identified and their extent was analyzed. Also, a mathematical model was developed to predict different forms of failure due to floods in North Bihar. It was observed that the height of flood has significant impact on the different parameters considered in this study.
The presence of feacal coliform indicates the presence of feacal material from warm-blooded animals such as Escherichia coli or Klebsiella pneumonae. Their presence can be taken as an indication of the potential danger of health risks those feacal possess. Members of two bacteria groups, coliforms and feacal streptococci are used as indicators of possible sewage contamination because they are commonly found in human and animal feces. Most commonly tested faecal bacteria indicators are total coliforms, feacal coliform bacteria, Escherichia coli, feacal Streptococci and Enterococci. The presence or absence of gas in each tube is used to calculate an index known as the Most Probable Number (MPN). There are two parameter used in this study that is, chemical and biological parameters. The present study was carried out on different site of Gomti River in Lucknow, U. P. The River Gomti passes through Lucknow, India and is the main source of drinking water for the city. Temporal variation in water quality of three major tributaries of the Gomti: Daliganj, Saheed Smarak, Hanuman Setu and Pipraghat were assessed based on data collected during January, 2012. In last to find out the variable number of bacteria in this study, so that maximum number of coliform bacteria /cells (41 cells/100 ml of water) at the ghat-2 on the site-B that is, Saheed Smarak and minimum number of bacteria /cells (8, 8 cells/100 ml of water) on the ghat- 1 and 2 at the Site- C that is, Hanuman Setu. The maximum number of feacal coliform bacteria /cells (12 cells/100 ml of water) on the ghat-1 at the site-D that is, Pipraghat, so that the minimum number of bacteria /cells (3, 3 cells/100 ml water of water) on the ghat- 2 and 3 at the site-B that is, Saheed Smarak to assess the low concentration of feacal mater so, this site has minimum number of bacteria /cells in the water sample.
Abstract With decreasing world oceans fish stock there is rapid increase in aquaculture production. To meet this demand, there is an urgent need to improve existing aquaculture technologies and make the system more sustainable and economically feasible. Diatoms are unicellular protists that are present ubiquitously in freshwater and marine habitats and are responsible for 40% of marine and 20% of net global primary productivity. They are the most preferred microalgae for production of live feeds in mariculture due to their suitable size, easy digestibility, and optimum nutritional content. Diatoms biosynthesize a range of bioactive compounds like lipids, polysaccharides, proteins, pigments, and vitamins which can both promote the health and survival of aquatic species like fishes, bivalves, and shrimps. As the main prerequisite to attain sustainability is to reduce pollutants from aquaculture wastewater, diatoms have long been employed for remediating and utilizing the eutrophic nutrients as a growth supplement which otherwise might be detrimental to aquaculture species. Though many recent studies have highlighted the significance of diatoms in aquaculture, its dual contribution in maintaining the nutritional content of the feed as well as in improving the water quality should be coupled with its unique mechanisms and adaptability. Thus, the current review addresses the bottlenecks in aquaculture industry and the prospects of implementing diatom‐based bioremediation and biomass valorization for the production of live feeds with the hindsight of establishing circular bioeconomy.
One of the most important stages of human development, adolescence, is full of opportunity for significant change. Education serves as a catalyst during this time of self-discovery, going beyond the limitations of typical academic settings. Taking center stage is holistic education, which recognizes the complex interplay between the intellectual, emotional, physical, social, and moral facets that shape the development of adolescents. This essay explores the essential elements of holistic education and the need to go beyond conventional educational paradigms in order to highlight the importance of empowering teenagers through this kind of education. It promotes adopting thorough evaluations that go beyond simple grades, embracing experiential learning techniques, and incorporating life skills education into academic courses. The study also explores the obstacles to holistic education implementation, such as standardized testing demands, budget constraints, and deeply ingrained reluctance to change in established educational systems.
In the present study, an attempt has been made to analyze the toxicity of fluoride and arsenic on morphology and behaviour of fish Clarias batrachus.Based on 96 hour LC 50 values at the 95% confidence limits of sodium fluoride (NaF) and arsenic trioxide (As 2 O 3 ) obtained from the preliminary tests, various sub-lethal concentrations of NaF and As 2 O 3 were selected for combined toxicity testing.During the experiment, fish were regularly observed for any changes in their external morphology and behaviour.Behavioural changes were observed in terms of air gulping, opercular movement, swimming activity, body position, general activity and food sensitivity.Control fish remained normal throughout the experiment period (96 hour) but erratic, exodus and speedy movements were found in all treated groups.The number of air gulps (per 15 min, 24-96 hour) significantly increased (P<0.001) in the exposed Group I (20 mg.L -1 As 2 O 3 ) as compared to control.A significant increase (P<0.01) in the number of opercular movements (per min for 24-96 hour) was recorded in treatment groups as compared to control.Apparent changes such as excessive mucous secretion, increased body discolouration, loosening of skin and complete loss of skin (head region and fins) were also observed.Skin loss was more intense in fish subjected to Group I.
