A critical assessment of technical advances in pharmaceutical removal from wastewater – A critical review

Use of pharmaceutical products has seen a tremendous increase in the recent decades. It has been observed that more than thirty million tons of pharmaceuticals are consumed worldwide. The used pharmaceutical products are not completely metabolized in human and animal body. Therefore, they are excreted to the environment and remain there as persistent organic chemicals. These compounds emerge as toxic contaminants in water and affect the human metabolism directly or indirectly. This literature review is an endeavour to understand the origin, applications and current advancement in the removal of pharmaceuticals from the environment. It discusses about the pharmaceuticals used in medical applications such diagnosis and disease treatment. In addition, it discusses about the recent approaches applied in pharmaceutical removal including microbial fuel cells, biofiltration, and bio nanotechnology approaches. Moreover, the challenges associated with pharmaceutical removal are presented considering biological and environmental factors. The review suggest the potential recommendations on pharmaceutical removal.The corresponding author Prof. Vinay Kumar is thankful to all the co-authors for their collaborative efforts in writing this paper.

A Secure Anonymous Proxy Signcryption Scheme

We introduce a new cryptographic primitive identity-based anonymous proxy signcryption which provides anonymity to the proxy sender while also providing a mechanism to the original sender to expose the identity of the proxy sender in case of misuse. We introduce a formal definition of an identity-based anonymous proxy signcryption (IBAPS) scheme and give a security model for it. We also construct an IBAPS scheme and prove its security under the discrete logarithm assumption and computational Diffie-Hellman assumption. Moreover, we do an efficiency comparison with the existing identity-based signcryption schemes and anonymous signcryption schemes and show that our scheme is much more efficient than those schemes, we also compare the efficiency of our scheme with the available proxy signcryption schemes and show that our scheme provides anonymity to the proxy sender at cost less than those of existing proxy signcryption schemes.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

An approach for multi-dimensional land subsidence velocity estimation using time-series Sentinel-1 SAR datasets by applying persistent scatterer interferometry technique

The time-series interferometric synthetic aperture radar (InSAR) techniques has the potential of estimating the land subsidence at a high accuracy of nearly in millimeter scale. The major limitation of the present InSAR methods like persistent scatterer interferometry (PSI) is that they measure land deformation velocities only in the direction of the radar line of sight (LOS). Hence, the real prospects of the deformation velocity, i.e. the horizontal and vertical components of velocity remain uncertain. This study is focusing on retrieving PSI based multi-dimensional land deformation velocity along horizontal and vertical directions in an urban region by using ascending and descending pass Sentinel-1 datasets. The area for this study is Lucknow city in Uttar Pradesh state of India. The estimated LOS velocity vectors from ascending and descending pass time-series datasets are utilized for retrieving multidimensional subsidence velocity. Further, the retrieved time-series land subsidence is correlated to the groundwater level variation during the considered time span

Morphogenetic Studies and In vitro Propagation of Two Mosses: Philonotis thwaitesii Mitt. and Brachythecium plumosum (Hedw.) B.S.G.

Well differentiated gametophytes of Philonotis thwaitesii Mitt., an acrocarpous moss and Brachythecium plumosum (Hedw.) B.S.G., a pleurocarpous moss have been raised in vitro by inoculating their spores into a range of concentrations of inorganic media. Half-strength Knop’s macronutrients + Nitsch’s trace elements with 10 ppm ferric citrate was found the most suitable for growth and multiplication of these species in continuous light of 4,000-5,500 lux and at 21 ± 2ºC temperature. Protonemal buds developed on caulonema in P. thwaitesii while on chloronema in B. plumosum. Sucrose stimulated caulonemal differentiation, abundant rhizoid production and a few but much robust gametophyte development. Emergence of hyaline rhizoids like filaments has been observed in P. thwaitesii upon contact of gametophores with solid substratum while true rhizoids all along the length of gametophytes of B. plumosum emerges upon placing them horizontally on culture medium. Variable growth forms (weft-like branched as well as erect unbranched habit) have been observed in both species in culture conditions. Sub-culturing of P. thwaitesii gave rise to new population via passing through chloronemal and caulonemal stage while B. plumosum directly regenerated into new gametophytes by-passing protonemal stage. In vitro raised plants were acclimatized and transferred to soil in order to their further proliferation

Load balancing technique based on hybrid resource utilization in cloud computing

Cloud computing uses the internet to supply dynamic services including memory, data, bandwidth and applications. Work schedules have an influence on cloud service reliability and performance. A proper provisioning method is required for a systematic resource allocation, which comprises of large virtual resources. Depending on the present state of the system, load balancing solutions can be distinguished as dynamic or static. Dynamic or static load balancing solutions can be employed to increase server response time or to raise load balancing factors for quicker and more efficient resource utilization. To decrease the load across resources and maximize CPU usage, a hybrid load balancing technique is developed. In the cloud, we have a finite quantity of resources that must be efficiently managed in order to fulfill tasks. Requests are transmitted to a cloud server, which assigns work via quadratic probing. During load balancing, the load is shifted from heavy-weighted servers to lighter-weighted servers, enhancing CPU usage. The suggested methodology's performance was assessed using average mean response time, make-span, average make-span, and average resource utilization. The Load Balancing Algorithm (LBA) is created with the primary purpose of reducing job completion time and increasing the average resource utilization ratio
