Occurrence of Additional Canals in Mandibular Lower Anteriors In Between Male and Female Patients

The endodontic treatment with excellent outcomes depends on the critical identification of the root and its canals anatomy. The successful identification of these anatomies guaranteed the pulp tissue extirpation completely, with efficiency in chemo-mechanical cleaning and shaping. All these lead to the most proper three-dimensionally root canal obturation with the most reliable inert filling. The purpose of this study is to provide clinical data on the presence of additional canals in mandibular anterior teeth among males and females.Patients reported from June 2019 to March 2020 were reviewed. 82000 patient records were reviewed and data related to patients undergone Root canal therapy in mandibular lower anteriors. Data includes age, gender and number of additional canals in lower anteriors. The collected data was tabulated in the excel sheet. Statistical analysis was done using SPSS software (version 9.0.3). The prevalence of patients with additional canals in mandibular anteriors was 8.1% . For females, the prevalence of additional canals was 3.24% whereas in males it is 4.86%. However, there is no relation between the gender and presence of additional canals in mandibular anteriors

Power Scheduling Scheme for a Charging Facility Considering the Satisfaction of Electric Vehicle Customers

Electric vehicles (EVs) are rapidly becoming a popular choice for transportation due to their low emissions and high fuel efficiency. However, one of the major challenges in EV adoption is the lack of charging infrastructure and the potential for grid overload during peak demand. To address these challenges, we propose a power scheduling scheme for a charging facility that optimizes power utilization and enhances the user experience of the EV drivers. The scheme considers the satisfaction of vehicle users by balancing the charging demands of the vehicles with the power supply capabilities of the facility. Our results demonstrate that the proposed scheme effectively reduces charging time and enhances the accessibility of charging stations, thereby improving the user experience, and encouraging EV adoption. The scheme also optimizes power utilization and reduces peak demand on the grid, thus contributing to the overall sustainability of the transportation system

Performance assessment on manufacturing of unfired bricks using industrial wastes

This paper presents eco-friendly unburnt bricks made up of fly ash, waste plastic powder, waste glass powder, lime, gypsum and crusher sand as alternatives to conventional burnt clay bricks for sustainable development. The research focuses on the maximum utilization of industrial waste in eco-friendly unburnt brick production. Materials are characterized according to their chemical and geotechnical properties. In this research, we use a milled waste glass powder of size less than 600μm and plastic powder obtained from plastic waste of size less than 600μm are added along with crushed sand, gypsum, lime and fly ash with various mix proportions concerning FaL-G mix concept. All the proportions were taken on a weight basis. Compressive strength, water absorption, and efflorescence are the key parameters chosen for comparing the innovative brick with conventional fly ash brick. There are five different mixes (Type A, B, C, D & E) are made in this research. The plastic and glass powders are replaced by crusher sand at the increased rate of 2% in every mix whereas 2%,4%,6%,8%, and 10%. It was found that the type B bricks have 17.63% strength was increased when compared to base mix. From the test results, type B bricks have enhanced mechanical performance when compared to all other mixes

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

SMART PATROL ALLOCATION SYSTEM

The increasing crime rate in smart cities demands a “smart” way to handle the situation. The objective of this article is to propose a methodology to strategically place a minimum number of police patrollers at road junctions such that positioning of the patrollers will achieve maximum visibility of the given geographical command efficiently. The notion of dominating set is applied to find the strategical locations at which the patrollers have to be placed. Also to allocate given patrollers optimally on these strategical locations we employ a priority based allocation to allocate them on the nodes that demand a higher importance. To experiment, the proposed model is tested for a place in Chennai, Tamilnadu, India. The results show that by only placing the patrollers on 1/3 of the total number of junctions, spatial visibility of all the junctions in the geographic command can be achieved. If provided with the number of patrollers available to be allocated, then the algorithm can optimally allocate the given patroller
