Early estimation of the case fatality rate of COVID-19 in mainland China: a data-driven analysis.

Background An ongoing outbreak of pneumonia caused by a novel coronavirus [severe acute respiratory syndrome coronavirus (SARS-CoV)-2], named COVID-19, hit a major city of China, Wuhan in December 2019 and subsequently spread to other provinces/regions of China and overseas. Several studies have been done to estimate the basic reproduction number in the early phase of this outbreak, yet there are no reliable estimates of case fatality rate (CFR) for COVID-19 to date. Methods In this study, we used a purely data-driven statistical method to estimate the CFR in the early phase of the COVID-19 outbreak. Daily numbers of laboratory-confirmed COVID-19 cases and deaths were collected from January 10 to February 3, 2020 and divided into three clusters: Wuhan city, other cities of Hubei province, and other provinces of mainland China. Simple linear regression model was applied to estimate the CFR from each cluster. Results We estimated that CFR during the first weeks of the epidemic ranges from 0.15% (95% CI: 0.12-0.18%) in mainland China excluding Hubei through 1.41% (95% CI: 1.38-1.45%) in Hubei province excluding the city of Wuhan to 5.25% (95% CI: 4.98-5.51%) in Wuhan. Conclusions Our early estimates suggest that the CFR of COVID-19 is lower than the previous coronavirus epidemics caused by SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV).
Light microscopy and SEM evaluation of three different fissure sealants

The aim of this study was to determine the stereo-light microscope and SEM evaluations of three sealant agents which have different chemical structures and filler contens: a compomer based pit & fissure sealant (Dyract® Seal), a sealant with high filler (Ultraseal XT), flowable pit & fissure sealant (Delton® FS). 45 extracted human molars were randomly assigned to 3 groups. Then each tooth was sectioned into two portions bucco-lingually, resulting in mesial and distal tooth halves, using an Isomet cutter. The penetration in depth and adaptation of these three materials were evaluated. The results were statistically analyzed with one-way analysis of variance (ANOVA) at a confidence level of 95% (p = 0.05). A post-hoc Tukey HSD-test was used for comparisons between groups. 46.7% of the teeth with Delton agents, 40% of Ultra-seal XT and 20% of Dyract-seal were sealed the whole depth of the fissure. While the sealant with less filler content penetrated better the whole fissure, the one with alcohol conditioner adapted best to the enamel walls. It was concluded that fissure shapes were as important as the sealant material content as regards the penetration. In U-shaped and medium depth fissures there was a better adaptation to enamel.
Comparative studies on physico-chemical, biological and enzymatic properties of soil amended with organic manure, vermicompost and indigenous microorganisms (IMOs)

Comparative studieswere conducted on physico-chemical,microbiological and enzymatic properties of soil supplemented with organic fertilizers, Organic manure, Vermicompost and Indigenous microorganism (IMO). Supplementation of organic and microbial amendments, improved physicochemical and biological parameters in soil. Higher water holding capacity, moisture content, and electrical conductivity, organic carbon content and bacterial and fungal populations are observed in test soil than control. Improved physical properties, EC, WHC contents were noticed in vermicompost soil. Whereas Higher biochemical properties like Total C, N,P contents observed in IMO treated soil. Nearly threefold higher bacterial and fungal population observed IMO treated soil than control. Soil enzymes, protease and cellulasewere enhanced in IMO treated and Vermicompost soil than without treatments.With increasing the soil incubation period soil enzyme activities were enhanced up to 14th day interval and thereafter declined in both test and control soil. Improved physicochemical, microbial and enzymatic parameters in organic manure, vermicompost amended soils are an indication of improvement of soil health and fertility.

Dietary Change Interventions for Undergraduate Populations: Systematic Review and Recommendations

ABSTRACT Background: Research demonstrates a decline in healthy eating behaviors during transitional years at university, potentially leading to weight gain and establishing maladaptive dietary habits. Purpose: This systematic review assessed the efficacy of previous nutrition interventions for undergraduates, evaluating design and implementation. Methods: Boolean phrases searched were “nutrition OR healthy eating,” “undergraduate*,” “pilot study OR intervention*,” and “college OR university. ” Articles were included if they were peer-reviewed, published in the last 10 years, and described complete interventions targeting undergraduates that included dietary behavior change, or the intention for change, as an outcome. Results: Of the 10 programs examined, only 4 showed significant increases in fruit and vegetable consumption, 1 showed an increase in fruit purchase, and 1 resulted in an increase in fruit consumption. The majority of interventions (n = 7) simultaneously targeted other health behaviors, and only one addressed environmental changes. Methodology was varied and inconsistent. Discussion: Limited success in undergraduate nutrition interventions may be the result of targeting multiple behaviors and a lack of evidence and theory-based design. Translation to Health Education Practice: Theory-based studies exclusively focused on dietary behaviors are needed that address social norms, upperclassmen and nonresidential students, environmental supports, feedback, goal setting, and measures aside from fruit and vegetable consumption.
A Comparative Analysis of Image Contrast Enhancement Techniques based on Histogram Equalization for Gray Scale Static Images

Contrast enhancement of digital images is conveniently achieved by spreading out intensity values over the total range of values, known as Histogram Equalisation. Since the enhancement is defined as the processing of an image to achieve more suitable than original image, it is purely application dependent and well proved with the simulation results of various image enhancement techniques. In this paper, we evaluate the performance of different Histogram Equalization techniques proposed for gray scale static images. In order to evaluate, the performance of these techniques, are examined on the basis of AMBE, PSNR and Entropy metrics. In this process enhancement techniques are applied on the images with different sizes and received from different application fields like real images, medical images etc. It is well illustrated in this paper that Brightness Preserving Dynamic Histogram Equalization (BPDHE) is the most suitable technique in terms of mean brightness preservation as it has least average AMBE value. In terms of PSNR, MPHEBP is the most suitable technique because it has the highest average PSNR value. In terms of Entropy, BBHE and RSIHE(r=2) are the best techniques, since these have the highest average Entropy values. The performance of BPDHE is not satisfactory in terms of Entropy.
Challenges & Solutions Of Adoption In Regards To Phone-Based Remote E-Voting

: Remote Voting Systems has not been universally adopted by most countries for their elections such as in the case of Fiji. Although mobile phones are quite prevalent around the world and the amount of smart phones sold is increasing at a rapid rate, there have not been many elections which have capitalized on the use of Mobile Phones as a remote voting tool. This paper is a limited review of previous papers on remote voting systems. The aim was to study challenges of adoption of remote e-voting systems such as through a mobile phone and suggest innovative solutions to those challenges. As such we propose a combination of new policy solutions and technical solutions such as the use of QR code and checksum for vote verification, the use of real time facial recognition systems, and the leveraging of existing mobile hardware to ensure a secure, anonymous and trustworthy remote voting system like it has never been before
Cardiac Involvement in Systemic Lupus Erythematosus Patients: Imaging Approach

Background: Lupus myocarditis is a potentially life-threatening condition. It can be oligosymptomatic or even silent. Lupus myocarditis necessitates a reliable imaging tool for early detection. Objective: This study aimed to assess myocardial edema in active Systemic Lupus Erythematosus (SLE) patients with T2 weighted dual inversion recovery black blood sequence. Methods: Cardiac MRI was performed on 20 active SLE patients (17 females and 3 males) with no history of previous cardiovascular diseases. Transthoracic echocardiography was performed for all patients. Results: Functional MRI analysis revealed preserved EF% (n=12) and reduced EF% (n=8). A highly statistically significant correlation between EF measured by ECHO and CMR was detected. The analysis revealed an excellent agreement between the two measures, ICC=0.753. Myocardial edema was noticed in 5 patients. One case showed delayed enhancement in LGE images and 7 patients (7/20) had pericardial effusion successfully diagnosed by both echocardiography and CMR. Conclusion: T2-double IR black blood imaging identified the worthy percentage of myocardial edema in active SLE patients, even in absence of clinical symptoms, denoting early myocardial involvement. Thus, cardiac MRI is a potential non-invasive diagnostic tool for cardiac surveillance in SLE patients.
A Novel Domino Logic for Arithmetic Circuits

—This paper presents a low power and high speed ripple carry adder circuit design using a new CMOS domino logic family called feedthrough logic. Dynamic logic circuits are important as it provides better speed and has lesser transistor requirement when compared to static CMOS logic circuits. The proposed circuit has very low dynamic power consumption and lesser delay compared to the recently proposed circuit techniques for the dynamic logic styles. Problems associated with domino logic like limitation of non-inverting only logic, charge sharing and the need of output inverter are eliminated. The feedthrough logic (FTL) performs a partial evaluation in a computational block before its input signals reach a valid level, and performs a quick final evaluation as soon as the inputs arrive, leading to a reduction in the delay. The FTL is well suited to arithmetic circuits where the critical path consists of a large number of gates. A comparison has been done by simulating the proposed logic style based 10-bit ripple carry adder along with previous logic styles based RCAs. The results show that FTL is the simplest, fastest and consumes least power.
Analysis on the Robustness SVD-Based Watermarking Algorithms

—This paper deals with the testing of the robustness of two algorithms for embedding and extraction of digital watermark into a monochromatic image, based on SVD transformation. The first algorithm was proposed by Liu and Tan [1], and the second, named Technique 1, was proposed by Moham-mad et al. [3]. In the first part of the paper, the influence of the watermark contents on the the image for both algorithms was analyzed. Thus, the optimal scale factor of embedding watermark was determined. Then, the images with the watermark were tested under the conditions where various deformations were applied. The robustness was analyzed as well on the basis of objec-tive and subjective parameters. In the second part of paper, impulse noise with percentage of 10-50% was added to the watermark images. Then, an efficient algorithm for impulse noise elimination was applied. The watermark was extracted from the re-constructed images and its quality was analyzed on the basis of subjective and objective parameters. PSNR and correlation coefficient rcorr were used as objective parameters. The visibility of the extracted watermark was used as a subjective parameter. On the basis of the results, an estimation of the robustness of the tested algorithms was made.
Nutritional Evaluation and Antioxidant Activity of Zest obtained from Orange (Citrus sinensis) Peels

Oranges (Citrus sinensis) are very important in fruits and contain very important nutritional components which have medicinal importance as well. The zest of orange peel was obtained by scraping out outer most colored covering of orange peel. The aim of this study was to evaluate the nutritional significance and antioxidant activity of zest obtained from orange peel. Data revealed that orange outer most covering (zest) had higher amount of fiber 5.01%. The total moisture content (4.716%) and total ash content (0.0338%) were calculated in dried sample of orange peel zest. Protein, Fat and carbohydrate contents were 3.00, 1.65 and 10.70 % respectively. Antioxidant activity demonstrates the different inhibition percentage at different concentration. Antioxidants keep the DNA of healthy cells from mutating into cancerous cell, so antioxidants are the first line of defense for cancer and other serious disease. Heavy metals Cd, Pb, Ni, Co, As, Cr were not detected in zest of orange peel.
Early Selection Potential of Gmelina arborea Roxb. Clones Based on Physiological Correlations of Their Nursery-Field behavior

The development of superior genetic materials points out the need to identify parameters for early selection of superior genotypes. The aim of this research was to identify possible correlations between young-adult materials, based on their photosynthetic capacity determined in five genotypes evaluated at nursery and 15-months-old field stages. Light response curves and gas exchange were generated. Physiological behaviors of five clones were assessed, both at rooted mini-cuttings stage and at 15-months old field stage, where 5 trees (ramets) per clone in each of both stages were evaluated. The water use efficiency in nursery (WUE-N) reported positive and moderate to strong correlations for all genotypes, with respect to Pn-F (net photosynthesis in field) and WUE-F. The same parameter in the field (WUE-F) correlated moderately and directly with P n-F (r = 0.5), whereas Gs-F and E-F was inversely and strongly correlated (r = -0.66 and r = -0.82 respectively). The chlorophyll content in rooted mini-cuttings leaves (Cloro-N) correlated directly with Pn-F, which suggests that a measurement of chlorophyll content could identify genotypes with a higher net photosynthesis later on in the field. These results evidence the possibility of early selection of G. arborea superior genotypes using physiological parameters.
Incidence of endometriosis in infertile women: clinical and laparoscopic characteristics

Introduction: Endometriosis is a common disease affecting women of reproductive age. Prevalence of endometriosis in general population is difficult to determine and is seen to affect approximately 33% women suffering from chronic pelvic pain and in 10% of adolescents and young adults with severe dysmenorrhea, largely estimated by laparoscopic visualization of the pelvic organs. Aims and objectives: To determine the incidence of endometriosis as well as the clinical and laparoscopic characteristics in infertile women with endometriosis. Materials And Methods: Medical records of all women presenting to gynaecologic clinics with primary complain of primary or secondary infertility and were subjected to diagnostic laparoscopy and dye test and were diagnosed to have endometriosis as the cause of infertility were included in the study. Results: Out of 102 medical files that were analyzed, endometriosis was reported in 16 (15.68%). The average age was 29±3.9 years. 64 patients had primary infertility (62.74%) and 38(39.26) secondary infertility. In 3 patients endometriosis (18.75) was minimal, mild in 4 (25%), moderate in 6 (37.5) and severe in 3(18.75). In severe endometriosis the predominant symptom was the moderate or severe dysmenorrhea, while in mild and moderate endometriosis was mild dysmenorrhea (p < 0.007). Conclusion: Endometriosis with infertility is not an uncommon disease and clinical symptoms and most clinical signs do not correlate with laparoscopic stage of the disease. Therefore it is difficult to predict stage or prognosticate the outcome based on clinical findings alone laparoscopy remains the preferred technique for diagnosis as well as staging of endometriosis.

The present study incorporated examination of the rumen of sheep infected with Paramphistomum SPP. On microscopic examination, it was found that, in the ruminal sections infected with mature Paramphistomum spp changes were observed only in the number of ruminal papille. But the sections infected with immature worms, hemorrhagic lesions and necrosis of the mucosal cells were observed. The mucosa was found thickened swollen, rugous and ulcerated. Thus it is concluded that the immature forms of paramphistomum spp caused more severe damage to the ruminal tissue whereas adult form inflicted mild tissue damage in the rumen of
Effect of duration and type of tobacco consumed on the Nasal Mucociliary Clearance of adult male smokers – a cross sectional study

Introduction: Nasal Muco Ciliary (NMC), one of the important protective mechanisms of respiratory tract is affected due to workplace and environmental exposure to dust, thereby exacerbating respiratory diseases. Prolonged NMC is the outcome of the exposure of nasal mucosa to toxic products of tobacco. The present study was planned to evaluate the relationship between the duration and type of tobacco usage on the NMC in adult males. Materials and Method: After obtaining ethical clearance, the cross sectional study was conducted on 60 male tobacco users (20 45 years), working in Housekeeping Department of Saveetha University Campus, Chennai. NMC was measured using Saccharin test. Mean NMC of tobacco users who were categorised based on duration and type of tobacco was compared using one way ANOVA. Results: Mean NMC of tobacco users was found to be higher (495.64±372.25 secs) than non users (388.11±173.89 secs). Mean NMC of smoked tobacco users was higher (569.26±503.52secs) than smokeless tobacco users(442.34±215.39secs). Among smoked tobacco users, smokers of bidi (667.5±537.16secs) had higher mean NMC than cigarette smokers (247.8±145.8 secs). It was observed that smokers who consumed tobacco for > 5 years and > 1 pack per day had the highest mean NMC (566.54±446.97 secs). Conclusion: NMC was prolonged in users of tobacco, particularly in users of smoked tobacco (bidi). Also NMC was directly proportional to the duration of tobacco consumption. The authors wish to highlight the need for relevant awareness and education on cessation of the tobacco usage among smokers.
