    This paper presents results of an experimental investigation, carried out to study the effects of admixture like rice husk ash (RHA) on the strength properties of a locally available clayey soil with soft consistency. This soil was mixed with different proportions of RHA (3%, 6%, 9% and 12% by weight of dry soil) at corresponding optimum moisture content (OMC) and also at moisture contents 2% and 5% above optimum moisture content (OMC+2%), (OMC+5%). The cost of stabilization may be minimised by using the agricultural waste materials like RHA which also minimises the environmental hazards. The laboratory test results show marked improvement of strength of soil on addition of admixture (RHA) in terms of California Bearing Ratio (CBR). It appear from the experimental results, soaked CBR value of untreated soil is 3.50% and reaches maximum value i.e 16.80% when mixed with 9% RHA at the respective OMC. Further, an attempt has been made to observe the effect of moisture on the strength properties of the original as well as stabilized soil. The paper highlights the use of RHA for sub-grade improvement in case of low cost roads

    In the present study Inhibin was purified from goat ovarian follicular fluid by Gel filtration chromatography on Sephacryl S-200. SDS PAGE of purified inhibin revealed the molecular weight of 55 kDa. The purified follicular fluid had been found to be immunoreactive by DID test and Western Blot analysis when treated against hyperimmune sera

    The objective of the present study was detection, isolation, partial purification and immunobiochemical characterization of fertility associated protein in the seminal plasma of high prolific Karan fries bull. Seminal plasma of Karan Fries bull was partially purified by gel filtration chromatography and analyzed by 10% SDS-PAGE for their polypeptide profile. PAGE analysis revealed major band of 55 kDa, and 26 kDa. Hyperimmune serum was raised in rabbit against crude seminal plasma protein. Single precipitin line was observed in DID test when each of the partially purified 26 kDa and 55 kDa proteins were reacted with hyperimmune serum. These proteins were also found to be immunoreactive against hyperimmune serum in Western blot technique

    In the present study Immunoglobulin G was purified from serum of Yak by gel filtration chromatography on Sephacryl S-200. SDS- PAGE of purified yak IgG showed four major polypeptides of 62.94 kDa, 53.29 kDa 29.22 and 28.21 kDa. The purified Immunoglobulin has been found to be immuno-reactive by DID test and Western Blot analysis when treated against hyper-immune sera

    Role of living conditions and socioenvironmental factors on chronotype in adolescents

    An individual's chronotype, defined as the preference for rest and activity at different times of the day, is linked to several physiological and psychological outcomes. Research on environmental determinants of chronotype has focussed mostly on geographic location, whereas other socioenvironmental determinants have been neglected. We aimed to investigate the association between other previously unrecognized socioenvironmental factors and chronotypes in adolescents. We analysed data of 1916 Bengali adolescents (aged between 13-14 years, 47% girls). Chronotype was determined by the reduced morningness-eveningness questionnaire (rMEQ), and socioenvironmental factors were identified through a structured questionnaire. Associations were analysed using multinomial logistic regression models. Our findings demonstrated that living in urban areas, the presence of a smoker at home, and higher parental education were associated with a higher evening activity (eveningness), while the use of biomass cooking media (compared to liquefied petroleum gas) and assisting parents in farming were associated with higher morningness in adolescents. This is the first study to identify the association between previously unrecognized socioenvironmental factors and chronotypes delineating the interaction between environment and sleep in adolescents and might help the parents to understand the importance of a proper sleep-activity rhythm of their kids through a comprehensive understanding of their surrounding environment and other factors

    In the present study Immunoglobulin G was purified from serum of dog by gel filtration chromatography on Sephacryl S-200. SDS- PAGE analysis of purified dog IgG showed major polypeptides of 66 kDa, 52.40 kDa and 20.72 kDa. The purified Immunoglobulin has been found to be immune-reactive by DID test and Western Blot analysis when treated against hyperimmune sera which was raised in rabbit

    Plasma mineral profiles and hormonal activities of normal cycling and repeat breeding crossbred cows: A comparative study

    No full text
    Aim: The present study was carried out to compare the associated role of micro minerals and hormones in repeat breeding animals with the normal crossbred cows. Materials and Methods: Blood samples were collected from 10 normal cycling and 10 repeat breeding crossbred cows of Ramakrishna Mission Ashram, Narendrapur to study the plasma mineral profile and hormonal activities. Results: Zn was found to be highly significant (p<0.01) between the two groups. Follicle stimulating hormone (FSH) and progesterone showed significant (p<0.05) difference in repeat breeding animal from the normal cyclic animal, whereas no significant differences were observed in Ca, P, Cu, Se, Co, luteinizing hormone and estradiol level. Conclusion: It may conclude that repeat breeding condition of crossbred cows in farm condition is mainly due to the low level of progesterone, FSH and zinc

    Efficient sequential sampling strategies for long-term environmental monitoring

    No full text
    Summarization: Assessments of resources at risk to anthropogenic pollution require extensive environmental monitoring. In addition, such assessments are required to have a long-term monitoring component in order to evaluate not only the status but also the trend of the resources at risk to ecological stresses. There is a need to identify statistical methodologies that would provide effective and cost-saving environmental monitoring designs, since such monitoring surveys are very expensive. In this paper the purely sequential, accelerated sequential, and three-stage procedures are evaluated as effective fixed-precision sampling procedures for environmental monitoring. Current monitoring designs utilize a sampling methodology where each resource is assigned a population inclusion probability, with the intent of describing the distribution of the whole population of resources at risk to anthropogenic environmental stresses. This study assumes that existing designs accurately describe the population distribution. A simultaneous fixed-precision estimation procedure is developed as an efficient method of estimating practically relevant percentiles of the cumulative distribution function, using water quality data from the Eastern Lake Survey as a lake population distribution. Accelerated sequential and three-stage procedures are shown to be better alternatives to the purely sequential procedure, requiring fewer sampling operations without any substantial loss of efficiency. Depending upon the precision required, all procedures showed potential reductions in sample size by as much as 60%. These types of designs for environmental monitoring are expected to be advantageous in national monitoring efforts directed toward the assessment of the status and trends of various ecological indicators.Παρουσιάστηκε στο: Water Resources Researc
