    Discarded waste tires are becoming a serious threat to health, environment, and ecological systems worldwide if it is not disposed of properly. Every year 1000 million of waste tires are discarded. This number may grow up to 1200 million by the year 2030. On the other hand, construction of civil engineering structures such as buildings, dams, highways, etc. are at high risk of differential settlement, especially in the case of weak or soft clay, which is due to its low shear strength and high compressibility. The paper aims to assess geotechnical properties of uncemented/cemented clayey soil incorporated with waste crumb rubber. Compaction parameters, unconfined compressive strength, split tensile strength, toughness index, CBR values and swelling pressure of rubberized uncemented/cemented clayey soil (3%, and 6% cement and different percentage of crumb rubber) have been obtained. After rigorous extensive study, it has been concluded that unconfined compressive strength and split tensile strength of rubberized cemented clayey soil decreases with the increase of the percentage of crumb rubber whereas the axial, and diametral strain are found to be increased with the addition of crumb rubber up to 5% after that it starts to decrease. The CBR values, swelling pressure, and toughness index of uncemented/cemented clayey soil was significantly affected by incorporation of crumb rubber. SEM studies have also been incorporated in this investigation

    Indian medicinal plants are the essence of Ayurveda and Ayurvedic treatments. When used judicially and clocking with the basic principles they produce miraculous effects. Fire flamed Bush (Woodfordia floribunda salisb), commonly called as Dhavari, Dhataki, belongs to the family Lythraceae. It is an important medicinal plant of tropical and subtropical India. Dhataki is a deciduous shrub, usually with a much fluted stem, spreading branches, 1-3 m high, rarely up to 7 m, commonly occurring throughout North India, ascending to an altitude of 1,500 m in the Himalayas, but rather scarce in South India. Acharya Charak quoted it among the fermenting agents (Asava yoni) and described under Purisasangrahniya, Mutravirajaniya and Sandhaniya group of drugs. The reported pharmacological activities of Woodfordia floribunda salisb. are antitumor activity, DNA inhibitory activity, immunomodulatory activity, antioxidant activities, antihyperglycemic activity, anti- inflammatory and analgesic properties, antimicrobial activity, hepatoprotective activity, etc. Dhataki is one of the major ingredient of many important formulations used in Ayurvedic system of medicine such as Dhatakyadi taila, Dhatakyadi curna, Pusyanuga curna, Brhat Gangadhara curna, Arvindasava. So this review paper is an attempt of the author to provide details of this medicinal plant Dhataki about its classical references, synonyms, botanical description, phytochemical and pharmacological activity and classical medicinal uses

    A REVIEW ON CHITRAKA WITH ITS MEDICINAL PROPERTIES W.S.R TO ITS AMA PACHAN AND AGNI DEEPANA ACTION

    Get PDF
    If we talk about Ayurveda, Science of life, the concept of AMA is unique. Ama is a Sanskrit word that translates literally to mean things like "unripe," "uncooked," "raw," "immature," or "undigested. Essentially, it is a form of un-metabolized waste that cannot be utilized by the body.To some degree, the formation of small amounts of Ama is a normal part of the digestive process, provided it is efficiently removed. But when it is not regularly cleared and eliminated, ama becomes hugely problematic. In fact, Ama is said to be the root cause of all disease, and Amaya, a Sanskrit word for disease literally means "that which is born out of Ama. The connection between Ama and the disease process makes perfect sense because the qualities of Ama are in direct opposition to those of Agni. Strong Agni is essential to the maintenance of proper health. In other words, when Agni is compromised and when Ama accumulates, our health suffers, and the two situations are mutually reinforcing. In Ayurveda, the concept of Agni, is of central importance. In fact, the strength of Agni in the body is among the most critical factors in determining overall health. By contrast, Ama is a toxic, disease causing substance that forms as a result of impaired Agni, and that, in turn, destroys Agni. In this way, impaired Agni and the creation of Ama routinely enter into a vicious and self-perpetuating cycle. Unfortunately, the accumulation of Ama is extremely detrimental to our health; it can lead to all kinds of imbalances and is a causative factor in any number of diseases. Ama pachan and Agni Deepana is the best concept to improve all heath issues, for this the wonderful drug Chitraka is mentioned in our Ayurvedic texts. Here in this article we are going to discuss about Chitrak & its medicinal aspect as mentioned in Ayurvedic texts

    Effect of inclusion of crumb rubber on the unconfined compressive strength and wet-dry durability of cement stabilized clayey soil

    Get PDF
    In the present study, the effect of inclusion of waste crumb rubber and cement on the unconfined compressive strength and wet-dry durability of clayey soil has been investigated. Crumb rubber and cement were added to clayey soil at ranges of 2.5%-10% and 3%-6% respectively. The results of the investigation revealed that the incorporation of crumb rubber influenced the unconfined compressive strength, axial strain at failure, energy absorption capacity and wet-dry durability of the cement-stabilized clay. The study reveals that as the content of crumb rubber in the cement-stabilized clayey soil increases the unconfined compressive strength decreases but prosperously changes the behavior of the cement-stabilized clay from brittle to ductile. The axial strain corresponding to peak axial stress and energy absorption capacity of the specimens can be increased by limiting the content of crumb rubber up to 5%. The weight loss of the cement-stabilized clay mixed with crumb rubber increases as the content of crumb rubber increases. With the prolongation of the curing period, the weight loss of cement-stabilized clay mixed with crumb rubber decreases. Further, the weight loss of 90 days cured specimens of clayey soil incorporated with 6% cement and crumb rubber up to 5% meets the recommendation of the material to be used in construction of road pavements as a base, sub-base, and shoulder. Most importantly, the utilization/disposal of this hazardous waste material reduces its impact on environment and health

    A Review of Organic Farming for Sustainable Agriculture in Northern India

    Get PDF
    In the post independence period, the most important challenge in India has been to produce enough food for the growing population. Hence, high-yielding varieties are being used with infusion of irrigation water, fertilizers, or pesticides. This combination of high-yielding production technology has helped the country develop a food surplus as well as contributing to concerns of soil health, environmental pollution, pesticide toxicity, and sustainability of agricultural production. Scientists and policy planners are, therefore, reassessing agricultural practices which relied more on biological inputs rather than heavy usage of chemical fertilizers and pesticides. Organic farming can provide quality food without adversely affecting the soil’s health and the environment; however, a concern is whether large-scale organic farming will produce enough food for India’s large population. Certified organic products including all varieties of food products including basmati rice, pulses, honey, tea, spices, coffee, oilseeds, fruits, cereals, herbal medicines, and their value-added products are produced in India. Non edible organic products include cotton, garments, cosmetics, functional food products, body care products, and similar products. The production of these organic crops and products is reviewed with regard to sustainable agriculture in northern India

    Perceived fear of COVID-19 and its associated factors among Nepalese older adults in eastern Nepal : a cross-sectional study

    Get PDF
    Coronavirus disease 2019 (COVID-19) has affected all age groups worldwide, but older adults have been affected greatly with an increased risk of severe illness and mortality. Nepal is struggling with the COVID-19 pandemic. The normal life of older adults, one of the vulnerable populations to COVID-19 infection, has been primarily impacted. The current evidence shows that the COVID-19 virus strains are deadly, and non-compliance to standard protocols can have serious consequences, increasing fear among older adults. This study assessed the perceived fear of COVID-19 and associated factors among older adults in eastern Nepal. Methods A cross-sectional study was conducted between July and September 2020 among 847 older adults (?60 years) residing in three districts of eastern Nepal. Perceived fear of COVID-19 was measured using the seven-item Fear of COVID-19 Scale (FCV-19S). Multivariate logistic regression identified the factors associated with COVID-19 fear. Results The mean score of the FCV-19S was 18.1 (SD = 5.2), and a sizeable proportion of older adults, ranging between 12%-34%, agreed with the seven items of the fear scale. Increasing age, Dalit ethnicity, remoteness to the health facility, and being concerned or overwhelmed with the COVID-19 were associated with greater fear of COVID-19. In contrast, preexisting health conditions were inversely associated with fear. Conclusion Greater fear of the COVID-19 among the older adults in eastern Nepal suggests that during unprecedented times such as the current pandemic, the psychological needs of older adults should be prioritized. Establishing and integrating community-level mental health support as a part of the COVID-19 preparedness and response plan might help to combat COVID-19 fear among them

    infection using mass spectrometry (MS). in mice infected with camel isolate. Homology driven searches for protein identification from MS/MS data led to most of the matches arising from related Trypanosoma species. Proteins identified belonged to various functional categories including metabolic enzymes; DNA metabolism; transcription; translation as well as cell-cell communication and signal transduction. TCA cycle enzymes were strikingly missing, possibly suggesting their low abundances. The clinical proteome revealed the presence of known and potential drug targets such as oligopeptidases, kinases, cysteine proteases and more. infections
