The management of mine fires in coal mining region is of much concern in India. Mine fires apart from economic aspects; give rise to devastating environmental effects. Most of th

PREPARATION OF PLANT MUCILAGE CLARIFICANTS AND THEIR EFFECT ON JAGGERY PROCESSING OF SUGARCANE VARIETY Co 86032

Objective: The aim of the study was to prepare jaggery from sugarcane variety Co86032 using plants mucilage as clarificants and to determine the effect of plant mucilage on jaggery processing.Methods: Production of jaggery using five plant clarificants namely Aloe vera, Flax seeds, Fenugreek, Purslane and Malabar spinach at three different concentrations i.e., 0.1%, 0.2% and 0.4% of raw sugarcane juice and the jaggery prepared without any clarificants serves as control. During production, the processing parameters such as quantity of scum removed, total time taken for processing and jaggery yield was determined.Results: It was found that the jaggery prepared using plant mucilage at concentration of 0.4% found superior when compared to 0.2%, 0.1% and control respectively. Aloe vera at 0.4% removed maximum scum (4.07%), taken minimum processing time (72.33 min) and recorded maximum jaggery yield (10.92 kg). The efficacy of Aloe vera as mucilage clarificants in jaggery production was followed by fenugreek, flax seeds, purslane and Malabar spinach in the order respectively.Conclusion: The application of plants mucilage as clarificants in the jaggery production removed significant level of scum, reduced processing time and improved yield of jaggery. Therefore the selected plant mucilages can be used as clarificants in the jaggery production and can be considered as potential alternative to chemical clarificants.Â

Overview of Cyberattack on Saudi Organizations

The beginning of Twenty first century saw a new dimension of security, the cybersecurity. Developed countries have started exploiting the vulnerabilities of cybersecurity to gain supremacy and influence over the rival countries. Hence, over the past decade, malware, i.e., malicious software, has become a major security threat in regards to the cybersecurity. The Kingdom of Saudi Arabia (KSA) has become a major target of cyber conflicts due to increased economic activity, digital transformation, high rate of technology adoption between citizen and organizations and rise of the oil and gas industry. However, unfortunately, there is a lack of research or scientific investigation of cyberattacks on KSA. This fact motivated us in conducting this work. This paper presents, a case study of attacks on Saudi Organization by malwares. We concentrate on two particular malwares: Shamoon and Ransomware. The timeline of attacks by these malware, also presented, along with their structures and methodologies in order to shield ourselves against similar attacks in the future

A Novel Approach for User Authentication for IoT Devices Using Human Pulse and IoT Cloud for OTP Generation

Internet of Things (IoT) integrates numerous devices into networks for providing intelligent and advanced services to the user community. With these devices that provide services to humans they should protect human privacy and secrecy. Many attacks are possible in the current world like DoS attacks, eaves dropping, user identity theft etc. To mitigate such attacks we develop an approach which uses human pulse for generating OTP and to authenticate the user based on OPT Authentication. This approach provides better authentication since the OTP is generated using IoT Cloud and pulse of humans which is dynamic in nature

Zirconia: Substitute for Metal Ceramics

In the search for the ultimate esthetic restorative material, many all-ceramic systems have been proposed. Dental research is nowadays directed toward metal-free prosthetic restorations in order to improve an esthetical outcome of crown and bridge restorations. Zirconia is a polycrystalline ceramic without a glassy phase and exists in several forms. Zirconia cores for fixed partial dentures (FPD) on anterior and posterior teeth and on implants are now available. This article is a review of zirconia crowns as replacement for conventional metal-ceramic crowns

Extra-articular distal tibia fibula fracture managed with single posterolateral approach: a case report

Extra-articular distal tibia fractures involve distal tibia approximately 4 cm within tibia plafond with no articular extension. The proper preoperative care, planning and selection of surgical approach is very essential to prevent postoperative wound-related complications. We present a case of a 29 year female patient, presented with left ankle pain and swelling with a wound over the medial aspect of the ankle. X-ray of the left ankle showed extra-articular distal tibia fibula fracture with no neurovascular deficit. We managed both the fractures with open reduction and internal fixation using a single posterolateral approach. At present 1 year follow-up, the patient is having a good range of ankle motion with radiological union with no implant failure and wound-related complications. Extra-articular distal tibia fibula fracture fixation using single posterolateral approach is a viable alternative approach to medial or anterolateral approach in cases of medial or anterior soft tissue problems. It helps in getting a better functional outcome, early mobilisation with less wound-related complications

DESIGN AND COMPARATIVE CFD ANALYSIS OF SHELL AND TUBE HEAT EXCHANGER

Heat exchangers are one of the most important components of the processing industries and also power plants. The pressure drop and the temperature variation in them are altered based on the component design as per operating parameters. As an integral part of design, baffles which are part of the heat exchanger serve the purpose in altering the pressure drop. In order to reduce the flow induced vibrations and reduce pressure drop different types of baffles are being designed and used and one such baffle is helical baffle. Helical baffles force the flow through the system be to be rotational and follow a helical path due to the geometry of the continuous helical baffles, which results in a significant increase in heat transfer coefficient per unit pressure drop in the heat exchanger. Besides this a properly designed continuous helical baffles can reduce fouling in the shell side and prevent the flow-induced vibration as well. In the current study an attempt has been made to understand the influence of baffle design on the pressure drop in the heat exchanger. A comparison was made between a segmental baffled, helical baffled and a bafflesless heat exchanger by designing the baffles and performing CFD simulation using CATIA V5 and ANSYS 15.0. It was concluded from the results that helical baffles which are our primary interest of study showed an effective pressure drop of 0.17134Pa which varied slightly from the other two. Further the pressure drop can be improved by modifying the design of heat exchanger with helical baffles

Prevalence of multidrug resistant uropathogens isolated from different age groups in South-India: a cross-sectional study

Background: Urinary tract infections (UTIs) continue to be one of the most common infections encountered by clinicians. The purpose of this study is to identify relevant multidrug resistance (MDR) patterns in South India.Methods: 401 urine culture samples with significant bacteriuria were collected from labs in South India between January 2019 and December 2020. Routine biochemical tests were conducted for primary identification of uropathogens. Antibiotic susceptibility testing was performed according to Clinical and Laboratory Standards Institute (CLSI) guidelines. Statistical package for the social sciences (SPSS) 16 and Microsoft excel were used to analyse data and determine MDR patterns.Results: The results showed that 54% of cultures with significant bacteriuria exhibited an organism with multidrug resistance. Of these, extended-spectrum beta-lactamases (ESBL) resistance was confirmed in 34.9%. Furthermore, over half (54%) of significant cultures were from outpatients. The incidence of UTIs was highest during the summer and at the lowest in the second phase of the monsoon season.Conclusions: Although the sample collection was limited to a few centres in South India, the results of our study justifies the rationale behind stringent regulation of antibiotic use and careful monitoring of antimicrobial resistance
