Association of Tooth Loss in Chronic Periodontitis Patients with And Without Mellitus

Tooth loss is a negative public health outcome that substantially affects not only the general and oral health status of people, but also their quality of life. Diabetes mellitus is one of the most widespread epidemics experienced worldwide; hence the aim of this study is to find the association of tooth loss in chronic periodontitis patients with and without diabetes mellitus. This cross sectional study consisted of a sample size of 547 patients of which 270 were diabetic patients and 277 were non diabetic patients and were distributed into two groups. After collection of data, it was tabulated with parameters such as name of the patient, age, gender, systemic condition, type of periodontal disease and tooth loss. The cast sheets of patients were obtained from the patient management software. The data of each patient was obtained and tabulated. The most common missing teeth were found to be upper anteriors and it had a higher prevalence of tooth loss in the non-diabetic group (26.82%) than in the diabetic group (18.43%). Association between tooth loss and systemic conditions was done using Chi square test p value- 0.008 and was found to be statistically significant. Tooth loss was higher in the age group of 61-70 years for the diabetic group and in the age group of 50-60 years for the non-diabetic group. The association between diabetes mellitus and periodontal disease is a well known fact. Therefore oral health education programs should be promoted in patients, which aids in early diagnosis and prevention of severe periodontal diseases

Performance Evaluation of GPU-Based WRF Model in Simulating a Unique Tropical Cyclone of Arabian Sea: A Case Study of VSCS Vayu

Tropical cyclone (TC) Vayu developed from a low-pressure system on 9 June 2019 near the West coast of India. Itunderwent rapid intensification (RI) to a very severe cyclonic storm (VSCS) before weakening into a deep depression on 17June 2019 with a unique track. The present study aims to evaluate the performance of the GPU-WRF model in simulatingthe unique tropical cyclone Vayu when initialized with different meteorological boundary conditions and the effect of inputof time-varying SST data, the track, and the cyclone's intensity. The study also aims to investigate the cyclone's synopticparameters during its development and intensification. Four simulations are conducted with GFS and NCEP-FNL data withand without SST input. The four-dimensional data assimilation analysis technique, the fdda analysis nudging scheme, wasused on the GFS data with SST input, which showed a significant improvement in track and intensity. The system skirtingthe Gujrat coastline on 13 June is skillfully captured. Given the appreciable improvement of track and intensity with GFSdata using nudging, further investigation of the cyclone's synoptic parameters is done on the same. Overall, comparing thesimulated dynamics with the ERA-5 dataset indicated that the model simulated a stronger TC. WRF can skillfully simulate awell-delineated eye wall at the matured stage (wind speed >40 m/s). An anomalously high mid-tropospheric relativehumidity (RH) (~90%) is indicated at the developing stage, indicating the onset of RI, during which the system showed RH~100% at the mid-troposphere. On 14 June, when the system reached VSCS, the simulated storm's low-level relativevorticity was ~359.93 × 10 –5 s-1, whereas ERA-5's was ~175.39 × 10 –5 s-1 only. The simulated storm cyclone energy(9.35×104 knts2) was lower than the observed (11.54 ×104 knts2). The significance of the results obtained from the study isthat the model can skillfully simulate the track and intensity of an Arabian Sea TC and capture TC Vayu's cyclogenesis. Thestudy also provides insight into the cyclone's synoptic parameters, such as mid-tropospheric relative humidity, low-levelrelative vorticity, and cyclone energy, during its development and intensification. The study's findings can be useful inimproving the accuracy of tropical cyclone forecasting and enhancing our understanding of the physical processes involvedin their formation and intensification for the Arabian Sea region

Plunging Ranula in a 78- year- old Male ? a rare case report

The term Ranula is a Latin word meaning frog. It refers to a bluish translucent cystic lesion in the floor of the mouth resembling the underbelly of a frog. Ranulas can be true cysts occurring due to ductal obstruction of the sublingual gland or a minor salivary gland or a pseudocyst as a result of ductal injury leading to extravasation and accumulation of saliva in the surrounding tissues. Clinically ranulas present as intraoral or plunging ranulas. The prevalence of ranula is 0.2% per 1000 patients Ranulas account for 6% of all salivary gland cysts. Ranulas are more common in children and young adults. However the plunging type occurs most commonly in the later third decade. The diagnosis of plunging ranula is based on a combined clinical,radiographic imaging and histologic findings. The treatment of ranulas have always been controversial.The treatment modalities range from simple marsupialisation to excision of the pseudocyst along with sublingual or submandibular gland excision.The purpose of this paper is to present a rare case of plunging ranula and to highlight the importance of considering plunging ranula in the differential diagnosis of lesions of the neck

The Quantum Internet: A Hardware Review

In the century following its discovery, applications for quantum physics are opening a new world of technological possibilities. With the current decade witnessing quantum supremacy, quantum technologies are already starting to change the ways information is generated, transmitted, stored and processed. The next major milestone in quantum technology is already rapidly emerging -- the quantum internet. Since light is the most logical candidate for quantum communication, quantum photonics is a critical enabling technology. This paper reviews the hardware aspects of the quantum internet, mainly from a photonics perspective. Though a plethora of quantum technologies and devices have emerged in recent years, we are more focused on devices or components that may enable the quantum internet. Our approach is primarily qualitative, providing a broad overview of the necessary technologies for a large-scale quantum internet.Comment: 38 pages, 1 tabl
