    Results from laboratory model tests performed on circular footing are presented in this paper to understand the performance of geocell reinforced expansive soil. Naturally occurring expansive soil was used in this study as subsoil. Geocells of chevron pattern fabricated from geotextile made up of polypropylene were used to reinforce the soil bed. The parameters studied in this testing program were the placement depth of the geocell mattress, pocket size of geocell and the height of geocell mattress. Contrary to other researchers; the improvement in the performance of reinforced bed is evaluated at a settlement level equal to the failure settlement of unreinforced soil bed. The performance of reinforced bed is evaluated through two non-dimensional factors viz. bearing capacity improvement factor (If) and settlement reduction factor (PRS%). Test results indicated that with the introduction of geocell as reinforcement, a substantial improvement in bearing capacity and decrease in footing settlement can be achieved. Bearing capacity of reinforced bed increases by more than 200% and 81% reduction in footing settlement was achieved by using geocell mattress of optimal dimensions and placing it just below the footing base

    Expansive soils like clays undergo swelling that can both be detrimental and acceptable in different applications. In the Northern part of India, especially Delhi region, natural soils containing clays & clayey sands support most of the buildings. Mechanically stabilized clays mixed with sand are used for local earthwork construction such as roads and landfills. Exact understanding of the swelling behaviour of such soils is a pre-requisite before the start of any construction projects. In this paper the swelling behaviour of clayey soil reinforced with geocell & Jute fibres has been presented. The laboratory investigations include one dimensional swelling tests using California Bearing Ratio (CBR) mould to study the swelling properties for different mix proportions. The maximum decrease in swelling potential of Geocell reinforced specimens was observed at fibre content of 0.80 percent and 40mm fibre length, beyond which increase in the swelling potential and swelling pressure has been observed. With this optimal reinforcement, a reduction of 71.24 percent in swelling and 41.10 percent in swelling pressure has been observed as compared to unreinforced soils. The study provides a solution towards the treatment of expansive soils before starting any construction activity over such soils and a step towards mitigating disasters related to infrastructure facilities grounded on expansive soils. Doi: 10.28991/cej-2021-03091728 Full Text: PD

    Curry leaves (Murryakoenigii), which are valued for their aromatic flavour, have been mainstay of Indian cuisine for ages. These leaves are becoming more well known for their potential to affect metabolic pathways in additional to their gastronomic value. The molecular mechanistic potential of curry leaves in relation to metabolic control is examined in this abstract. Curry leaves contain a variety of bioactive substance, such as antioxidant, anti-inflammatory agent, and substance that modulate insulin sensitivity, which have potential to have an effect on crucial metabolic processes. Their contribution to the management of oxidative stress, inflammation, blood sugar, cholesterol, weight, gut health, liver function, thermogenesis, and appetite regulation is discussed in this work. Although encouraging, more study is necessary to complete clarify the mechanism of action and to determine the efficacy of curry leaves in metabolic disorder

    The liver is the second-largest organ in our body which separates the nutrients and waste as they move through our biological process system and it additionally produces bile, a substance that carries toxins out of your body and aids in digestion. There are several myths associated with liver spread amongst masses. It is a vital necessity to make society devoid of such myths and aware of the real scenario. This review aimed to summarize the different facts and myths associated with health problems of liver and highlight the importance of food sustainability approach with the help of some case studies. A comprehensive literature search was conducted using various databases between 2006 and 2022 that focused on the various facts and myths associated with liver related health issues. Myths create nothing but false notions and fear amongst people. Some case studies were summarized to clear all the conflict statements commonly related with liver diseases in the society. Myths like nothing other than water is considered a good beverage for the liver, but recent studies have proven that measured quantities of coffee and herbal tea intake is healthy for the body. Additionally, coffee has a protective effect on the organ liver. Similarly, hepatitis can spread through casual contacts. Although it is proven that hepatitis B, C and autoimmune hepatitis, do not spread on having casual contact or sharing food and drink. A substantial myth states that blood tests can detect problems associated with the liver, but doctors rarely suggest blood tests for liver functioning. This review is focused to resolve several myths associated with the liver which are often considered true by masses
