Comprehensive analysis of security issues in cloud-based Internet of Things: A survey

The Internet of Things (IoT )has emerged as the largest computing platform, enabling IoT devices to sense real-world conditions such as temperature, humidity, pressure, and cloud prediction. However, the security of IoT systems is crucial due to their direct impact on human life. With the expansion of processing and communication capabilities to numerous devices, IoT has become a vast network where connectivity is ubiquitous. This paper focuses on the security issues of cloud-based IoT, specifically access control, network security, data security, and privacy, which are the four main components of cloud-based IoT. By analyzing and comparing existing research papers on security in cloud IoT and IoT in general, we identify proposed solutions. Most researchers have concentrated on a single component, while only a few have addressed two components. Consequently, our research aims to bridge the gap in Cloud IoT security by focusing on more than two components. We propose the utilization of methods such as Machine Learning and blockchain to enhance security, drawing on the strengths highlighted in previous works. Our future focus will involve exploring potential attacks in cloud IoT and developing a comprehensive method that encompasses atleast three security components of cloud IoT security

Study of Pesticide (Dichlorvos) Removal from Aqueous Medium By Arachis Hypogaea (Groundnut) Shell Using GC/MS

Abstract: KOH, H 3 PO 4 and ZnCl 2 catalyzed Groundnut shells, subjected to a one and two steps activation methods were employed to study pesticide (Dichlorvos) uptake. The study examined activation method, nature of activating agents and concentration of the pesticide, as factors affecting removal of the pesticide. Quantitation, using GC/MS gave a percentage removal of over 98% by all the sorbent in the series. The percentage removal for the one step method follows the trend 1S/KOH/10 (100%) > 1S/H 3 PO 4 /10 (99.780%) > 1S/ZnCl 2 /10 (99.240%). Physicochemical data and close proximity of equilibrium results (q e ) to those of similar biowaste as reviewed in literatures are indication that Groundnut Shell based sorbent in this study could compete favorably well for pesticide(dichlorvos) uptake.

Guillain barre syndrome as initial presentation of systemic lupus erythematosus

Background: Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterized by multiple organ involvement including the peripheral nervous system. Guillan- Barrè syndrome (GBS) has an established association with SLE as one of its neurologic manifestations. However, GBS as an initial manifestation of SLE is only sparingly reported in the literature.Methods: We present a case of a 26 year old woman who was initially managed by neurology unit for GBS but subsequently developed body swelling, hypertension and polyarthritis. She was evaluated and managed by both rheumatology and nephrology units.Results: Renal biopsy showed histological features of membranous nephropathy suggestive of stage V lupus nephritis. The patient responded well to high dose corticosteroid, intravenous cyclophosphamide and azathioprine.Conclusion: This case highlights that GBS can be an initial presentation of SLE and the usefulness of immunosuppressants in the management of such cases.Keywords: Guillan-Barrè syndrome, Systemic Lupus Erythematosus, Lupus Nephritis, Immunosuppressant
