    Effect of Confining Pressure on The Cement Treated Soil

    Low workability and high water content in soil cause many problems in construction industry. The best way to deal with this is to replace the existing soil by good quality soil which may not be feasible every time due to scarcity of good quality soil. This issue forces engineers to work on soil stabilization. Out of those many methods of soil stabilization, mixing an admixture like cement, fly ash etc., with soil is the most common method. These additives affect chemical and mechanical properties like bearing capacity, elastic behavior of treated soil, so an additive should be chosen depending upon the soil properties and purpose of stabilization. Unconfined compressive strength is also one of those important parameters which are taken into consideration during soil stabilization but in real life, soil has confining pressure because of the soil present around the specimen under consideration. To follow this actual field situation in analysis and design program, it’s necessary to check the effect of the confinement on the strength of the soil. This study mainly deals with finding out the effect of level of confinement on confined compressive strength of the cement treated soil at different cement to soil weight ratio and different curing periods. To have an idea about the strength of the soil without confinement, specimen for all proportions and curing periods are tested for unconfined compression strength and split tensile strength also

    The study presents a meticulous investigation into the catastrophic landslide that impacted Malin village in Pune district of Maharashtra, India. By employing a multi-faceted approach encompassing field, laboratory, and numerical analyses, in the study, stability governing parameters were thoroughly assessed with respect to varying levels of water saturation. Field investigation provided crucial insights into the geographical profile, field density, slope strata, and representative soil sample acquired from hill slopes. Furthermore, extensive laboratory investigations were conducted to gain a comprehensive understanding of the role of stability governing parameters under different water saturation levels. The limit equilibrium method was employed for numerical simulation to rigorously evaluate slope stability. The results revealed the significant influence of increased water saturation on stability governing parameters, leading to slope instability, which was confirmed by numerical simulation. The study further established that excessive rainfall triggered the landslide, saturating the soil mass and deteriorating the stability governing parameters, ultimately leading to instability. The findings of this study offer valuable insights for mitigating landslides and can be instrumental in developing effective monitoring and warning systems

    Impact of Flood on Prayag Chikhali Village of Karveer Tehsil in Maharashtra (India): A Comparative Analysis (2005-2006)

    During  the  last  two years (2005-2006) floods  caused  by  heavy  monsoon  rains  have  swamped  large  parts  of  western  and  central  India ,  including  the  states  of  Andhra  Pradesh,  Gujarat,  Maharashtra,  Chhatisgarh and  Orissa,  of  these  first  three  have  been  the  worst   affected . As many as 31 districts  in  Maharashtra  were  affected  by  flood ,  which  included  7, 375  villages  and  nearly  one  lakh  families. Besides that 468 people were died. The districts viz; Sangli, Kolhapur, Satara, Pune and Nashik in the western part of Maharashtra have been severely affected by flood due to the heavy rainfall during the monsoon. In Kolhapur, particularly Karveer, Shiroal and Hathkangale tehsils were severely affected by flood that included 711 villages. The focus of present study is to look into the severely affected village Prayag Chikhali and to compare the severity of floods occurred in the consecutive years of 2005 and 2006. The present study also intends to plan for controlling the floods and to minimize the flood affect in the area under study. Key words: Heavy rainfall, river flood, magnitude, frequency, flood impac

    THE ROLE OF INTERNET OF THINGS(IOT) IN SMART HEALTHCARE SYSTEM

    Get PDF
    Healthcare has evolved thanks to the Internet of Things (IoT) revolution. Health management has replaced treatment as the primary focus of healthcare. As a result, as healthcare develops toward patient-oriented and analytical applications, more data are being collected and pooled than ever before. In addition to discussing health data and patient-centred health management, this article also covers several facets of smart healthcare. One of the most important industries that the Internet of Things (IoT) has modernized is healthcare. The ability to collect data and evaluate this enormous data is made possible by the shrinking of sensors. IoT sensors can be used to connect medical equipment and resources in order to gather data and process it. This paper provides a overview of certain IoT's effects on the healthcare industry. Healthcare cannot be outside of this paradigm given the rise of IoT technologies. The purpose of this article is to provide guidelines for achieving worldwide connectivity between medical environments and the Internet of Things (IoT

    The amidine based colorimetric sensor for Fe³⁺, Fe²⁺, and Cu²⁺ in aqueous medium

    An amidine based chemosensor AM-1 was synthesized and characterized by various spectroscopic (FT-IR, 1H-NMR and mass) data and elemental analyses. Sensor AM-1 exhibited high selectivity and sensitivity towards Fe³⁺, Fe²⁺ and Cu²⁺ in the presence of other surveyed ions (such as Sr²⁺, Cr³⁺, Co²⁺, Ni²⁺, Zn²⁺, Ag⁺, Al³⁺, Ba²⁺, Ca²⁺, Cd²⁺, Cs⁺, Hg²⁺, K⁺, Li⁺, Mg²⁺, Mn²⁺, Na⁺ and Pb²⁺) with a distinct naked-eye detectable color change and a shift in the absorption band. Moreover, the emission of AM-1 was quenched selectively only in the presence of Fe³⁺
