Fake Detect: A Deep Learning Ensemble Model for Fake News Detection

Pervasive usage and the development of social media networks have provided the platform for the fake news to spread fast among people. Fake news often misleads people and creates wrong society perceptions. The spread of low-quality news in social media has negatively affected individuals and society. In this study, we proposed an ensemble-based deep learning model to classify news as fake or real using LIAR dataset. Due to the nature of the dataset attributes, two deep learning models were used. For the textual attribute “statement,” Bi-LSTM-GRU-dense deep learning model was used, while for the remaining attributes, dense deep learning model was used. Experimental results showed that the proposed study achieved an accuracy of 0.898, recall of 0.916, precision of 0.913, and F-score of 0.914, respectively, using only statement attribute. Moreover, the outcome of the proposed models is remarkable when compared with that of the previous studies for fake news detection using LIAR dataset.
SCRD-Net: A Deep Convolutional Neural Network Model for Glaucoma Detection in Retina Tomography

Early and accurate diagnosis of glaucoma is critical for avoiding human vision deterioration and preventing blindness. A deep-neural-network model has been developed for the diagnosis of glaucoma based on Heidelberg retina tomography (HRT), called “Seeking Common Features and Reserving Differences Net” (SCRD-Net) to make full use of the HRT data. In this work, the proposed SCRD-Net model achieved an area under the curve (AUC) of 94.0%. For the two HRT image modalities, the model sensitivities were 91.2% and 78.3% at specificities of 0.85 and 0.95, respectively. These results demonstrate a significant improvement over earlier results. In addition, we visualized the network outputs to develop an interpretation of the learned mechanism for discriminating glaucoma and normal images. Thus, the SCRD-Net can be an effective diagnostic indicator of glaucoma during clinical screening. To facilitate SCRD-Net utilization by the scientific community, the code implementation will be made publicly available.
Graft copolymers with a random distribution of pyrrole monomer with hydrophilic functionalities

An electroactive biomaterial was obtained from the electropolymerization of pyrrole (Py) monomer and a macromonomer called PAB53, which has pyrrole as backbone and chains of PEG2000 grafted. The copolymerization was carried out at a molar ratio of 1:1 of Py:PAB53 and at three polymerization times (300, 500 and 1000s), resulting in films with cauliflower-like structures as surface morphology in all cases. The topography, thickness and wettability increased proportionally to the polymerization time, attributed to higher concentrations of PAB53 in the resulting copolymer films. Therefore, the increase of PEG chains, which favors the formation of valleys and hills in the surface morphology, is also responsible for a higher hydrophilicity in the copolymer films. The electroactivity of the compounds were affected negatively with the incorporation on the PEG. However, the optical and conductive properties were good, showing a similar band gap than the semiconductor PPy homopolymer. It was established that the best film was the copolymer P(Py-co-PAB53) generated at 1000s, which was found to be an active surface for adsorption of BSA and Lyz proteins, the results revealed that the affinity of this copolymer is higher than the PPy homopolymer, suggesting that it is a promising polymer for bioengineering applications.
Discharge Summary Completion Timeliness and the Association of 30-Day Readmission

Avoidable readmission is an established quality metric, and communication is key. This study evaluated whether timely discharge documentation was related to lower readmissions. The authors found that patients with discharge summaries completed longer than 7 days after discharge had a significantly higher readmission rate than those completed within 7 days. Abstract Objective This study aimed to review the association between timeliness to completion of a discharge summary to 30-day readmission to the hospital. Methods This was a retrospective chart review of 109 patients discharged from Mayo Clinic Hospital. Results Twenty-four of these patients were readmitted within 30 days. The time to completion of discharge summary was categorized for these readmissions to <72 hours: 15 (20%), between 72 hours and 7 days: 2 (11.1%), and >7 days: 7 (43.7%). There was no statistical significance for readmission for discharge summaries completed between 72 hours and 7 days compared with <72 hours (P = 0.44). There was statistical significance correlating readmission within 30 days to the discharge summary completed >7 days compared with <72 hours (P = 0.04). Conclusions This study found that discharge summaries completed >7 days have an increased association with 30-day readmission rate.
EFFECT OF PH AND TEMPERATURE ON PIGMENT PRODUCTION FROM AN ISOLATED BACTERIUM

Various synthetic coloring agents have the potential of carcinogenicity and/or teratogenicity. Natural colors, extracted from fruits, vegetables, seed roots and microorganisms and often called “biocolors” due to their biological origin have proved to be safe and edible coloring agents. An unidentified, yellow pigment producing bacterium was isolated from soil in areas around Durgapur, West Bengal, India. Preliminary morphological observations revealed that the colonies were circular, convex and yellow in color. Gram staining reactions showed that the bacterium was Grampositive coccus. Colonies were grown in brain heart infusion medium with the aim to optimize temperature and pH for growth and pigment production. Pure colonies were grown at pH between 1 and 14 and temperature between 4C and 45C. Considerable growth and pigmentation was observed at temperatures between 15C and 40C and at pH between 6 and 10, with the maximum yield at pH 7 and 30C. The pigment was extracted by solvent extraction method using methanol. The pigment extracts were analyzed by scanning the absorbance with a UV-Vis spectrophotometer and peaks were obtained at 437 nm, indicating that the pigment is a possible carotenoid.
An Electrochemical Study to Evaluate the Effect of Calcium Nitrite Inhibitor to Mitigate the Corrosion of Reinforcement in Sodium Chloride Contaminated Ca(OH)2 Solution

The effect of calcium nitrite (Ca(NO2)2) was assessed by electrochemical means such as open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), and potentiodynamic studies in saturated Ca(OH)2 solution contaminated with 0.99 and 7.91 g/L NaCl. The preliminary results of OCP showed that the potential is shifted towards positive (noble) side as content of inhibitor increased. The EIS results indicate that Ca(NO2)2 works effectively in reduction and initiation of corrosion of steel rebar in NaCl contaminated Ca(OH)2 solution. Potentiodynamic studies revealed the pitting tendency of steel rebar exposed in 0.99 g/L NaCl at [Cl−/] = 1.2 attributed to low conductivity of passive film which causes interference for Cl− ions attack during anodic polarization. The 85.75% efficiency is found in 0.99 g/L at [Cl−/] = 1.2. The Ca(NO2)2 inhibitor transformed the unstable iron oxides/hydroxides into stable and protective oxides/hydroxides due to its strong oxidizing nature. Therefore, this inhibitor is sufficiently and significantly reducing the corrosion of steel rebar at even its low concentration with 0.99 and 7.91 g/L NaCl solution.
INFLUENCE OF HARVESTING TIME ON CHEMICAL COMPOSITION OF THE ESSENTIAL OIL OF ABIES KOREANA TWIGS

Objective: In the present study, the influence of harvesting time (April, June, August and October 2015) on the essential oil composition of Abies koreana twigs from Korea was investigated. Methods: The essential oil from the twigs of A. koreana was isolated by steam distillation and its chemical composition was determined by gas chromatography-mass spectrometry (GC-MS). Results: The essential oil yield was found to vary from 0.76 to 1.20% depending on the month of harvesting. The GC-MS analysis revealed the identification of 26 different essential oil components from the twigs harvested in the months of April, June, August and October, which were mostly monoterpene hydrocarbons (57.63–72.38%) followed by oxygenated monoterpenes (18.82–25.96%). Harvesting time mainly influenced on the concentration of the major components of the essential oil from the twigs of A. koreana . Limonene (17.38–31.13%), bornyl acetate (13.22–21.17%), camphene (12.56–13.26%), α-pinene (11.05–13.02%), β-pinene (4.55–5.70%), 3-carene (5.21–6.43%) and β-eudesmol (1.49–8.24%) were detected as the major components in the essential oil. Conclusion: The main differences between the essential oil compositions of four different months can be referred to limonene and bornyl acetate. The results showed considerable variations in the composition of essential oil, particularly quantitative variation during different harvesting months.
Rotating Ring–Disk Electrode Study of Oxygen Evolution at a Perovskite Surface: Correlating Activity to Manganese Concentration

Transition-metal oxides with the perovskite structure are promising catalysts to promote the kinetics of the oxygen evolution reaction (OER). To improve the activity and stability of these catalysts, a deeper understanding about the active site, the underlying reaction mechanism, and possible side reactions is necessary. We chose smooth epitaxial (100)-oriented La0.6Sr0. 4MnO3 (LSMO) films grown on Nb:SrTiO3 (STNO) as a model electrode to investigate OER activity and stability using the rotating ring−disk electrode (RRDE) method. Careful electrochemical characterization of various films in the thickness range between 10 and 200 nm yields an OER activity of the epitaxial LSMO surface of 100 μA/cm2ox at 1.65 V vs RHE, which is among the highest reported for LSMO and close to (110)-oriented IrO2. Detailed post-mortem analysis using XPS, XRD, and AFM revealed the high structural and morphological stability of LSMO after OER. The observed correlation between activity and Mn vacancies on the surface suggested Mn.
The mixing and separation of particle suspensions using oscillatory flow in baffled tubes

We report experimental observations on the way in which particles that would normally sediment in a liquid, can be maintained in suspension by the use of oscillatory flow in baffled tubes. In one regime of operation, a near uniform suspension of particles can be obtained and the intensity of the particle mixing varied by control of the frequency and amplitude of oscillation. In another regime, particle concentration profiles along the tube are observed and it is shown that this effect could be used to separate particles with different sedimenting characteristics. The experimentally observed particle concentration profiles are modelled using a simple numerical scheme
Food and Bioproducts Processing

Moisture sorption isotherms of EX-BORNO and SOSAT C88 millets at temperature range of 30–70 ◦C and water activity range of 0.07–0.98 were determined using the static gravimetric method. The sorption isotherms of both millet varieties decreased with increasing temperature, exhibited type II behaviour according to BET classification and hysteresis having loop size increasing with increasing temperature. This is as a result of the hard nature of the millet varieties. The moisture sorption and the data fitted well with Modified Henderson, Modified Halsey, Modified Oswin and Modified GAB models. The constants of the equations used in fitting were determined by non-linear regression analysis when the models were compared using the standard error of estimate, mean relative percent deviation, fraction explained variation and residual plots. The Modified Oswin model gave the best fit for the whole set of data. The study has provided information and data useful in large scale drying and processing of millet which have remained at the traditional level despite the importance of the drought resistance crop in poverty alleviation. © 2010 The Institution of Chemical Engineers.

Association between Sleep Disturbance with Weight-for-Height and Body Mass Index in Preschoolers

Introduction: Hormonal changes affecting a child's growth occur in deep sleep phase of preschoolers. Nowadays, obesity is still a world health problem. In 2014, Indonesia had three growth problems, one of them was overweight in preschoolers. This study aimed to analyze the association between sleep disturbance with weight-for-height and body mass index (BMI) in preschoolers. Methods: This was a cross-sectional study by analyzing the tendency with boxplot charts and the association was measured by Mann-Whitney test and independent t-test. Data of 86 preschoolers aged 3-5 years old were obtained from three kindergartens in Kalijudan, Surabaya from March to September 2018. Z-score values and the categories of weight-for-height Z-score (WHZ) and BMI-for-age Z-score (BAZ) refer to WHO Standards 2006 and sleep disturbances were measured by sleep disturbance scale for children (SDSC) questionnaire. Results: 65.12% of preschoolers had sleep disturbance and 66.28% of them had normal WHZ and BAZ. The average WHZ and BAZ value in preschoolers who had sleep disturbance (M = -0.2730; -0.2207) were higher than preschoolers who had no sleep disturbance (M = -0.6083; -0, 5920). Results from Mann-Whitney test showed the same significance value between WHZ and BAZ, p = 0.226. Independent t-test showed a significance value of p = 0.524 and p = 0.490, meaning that there was no statistically significant association. Conclusion: There was no statistically significant association between sleep disturbance with WHZ and BAZ in preschoolers aged 3-5 years old, however descriptively, the values of WHZ and BAZ in the group of preschoolers who had sleep disturbance tended to be higher.
SPECTRUM OF MRI FINDINGS IN PEDIATRIC EPILEPSY – MEDICAL AND SURGICAL CAUSES OF EPILEPSY IN CHILDREN AND ITS’ RADIOLOGICAL CORRELATION

Objectives: Epilepsy is the common condition encountered in both adults and pediatric population. It occurs as a result of various spectrum of etiology ranging from infections to tumors. EEG and Neurosonogram can characterized the type of epilepsy, however, imaging is the only tool to identify the lesion, its location, extent and resection possibility. CT was the only modality before the era of MRI. However, CT was only used to indentify the lesion with hemorrhage and calcification. It is having the disadvantage of having poor spatial resolution and using radiation. The era of MRI has changed the imaging due to its higher spatial resolution, gray white matter differentiation, status of myelination and non utilization of radiation. Purpose: The aim of study was to detect and characterize various lesions causing epilepsy in pediatric age group (0–12 years) and also to detect frequency with which they occurred using MRI. Methods: The study was performed on 50 children under the age of 12 years over a period of 1 year who presented with epilepsy. Patients with trauma and febrile seizure disorders were excluded. Conventional and contrast MRI was performed in all cases and lesions were characterized in location, signal intensity, and other

IN SILICO STUDY OF CEPHALOSPORIN DERIVATIVES TO INHIBIT THE ACTIONS OF Pseudomonas aeruginosa

Infections caused by gram-negative bacteria, such as Pseudomonas aeruginosa, have been spreading worldwide. It is a threat to public health because of its multi-drug resistance and difficulty to treat. Therefore, the demand for developing antimicrobial agents to treat infections is increasing. One of them that is currently under development is cephalosporin derivative compounds. This research studied the three-dimensional (3D) interaction between antibiotics from cephalosporin derivatives and penicillin-binding proteins (PBPs) in P. aeruginosa. This study aimed to clarify whether the cephalosporin derivatives were effective in inhibiting the activity of P. aeruginosa. The PBPs structure was obtained from the Protein Data Bank (PDB ID: 5DF9). The structural sketch of the cephalosporin derivative was drawn using the Marvins Sketch, whereas the study on the interaction between antibiotics and PBPs was carried out using the Mollegro Virtual Docker 6.0 program. The results showed the lowest rerank score from five cephalosporin derivatives, namely cephalotin (-116,306), cephotetan (-133.605), cephoperazone (-160.805), cephpirome (-144.045), and cephtaroline fosamil (-146.398).

Improvement of grain filling in rice through foliar spray by nutrients and growth promoters

An investigation was carried during 2018 at Department of Rice, Tamil Nadu Agricultural University, Coimbatore. The objective of the experiment was to identify the suitable foliar nutrient/ growth promoter for enhancing grain filling in rice. Three rice genotypes, ADT (R) 49, RICE CO 52 and CO 50 were grown under different foliar treatments. The treatments are 2% DAP+ 1% KCl, 2% MAP+ 1% KCl, ZnSO4 0.5%, 6-Benzylaminopurine 30 ppm, Homobrassinolide 0.3 ppm, NAA100 ppm and 1-MCP 20 ppm and the control plots were sprayed with water. Foliar spray was taken up at two stages, pre-anthesis (just before heading) and post-anthesis (2 weeks after flowering or during grain filling stage). The grain filling characteristics of rice genotypes significantly varied with the different foliar nutrients. The grain filling duration (25.0 days) significantly increases with the treatment 6 Benzylaminopurine (30 ppm) in the genotype Rice CO 52 and the grain filling rate (1.24 mg grain day) was found to be higher in genotype in the genotype CO (R) 50 under the treatment T3 – 2% MAP + 1% KCl. The hormone concentration in grains showed a significant increase with the different foliar application. High ABA and ethylene ratio was observed in the treatments. The treatment 1MCP (20 ppm) had recorded the high ABA and ethylene ratio in superior grains in the genotype Rice CO 52 (7600.0) and in inferior grains (954.6) followed by the genotype ADT (R) 49 (4250.0 and 833.3) in the superior and inferior grains respectively.The maximum grain yield of 8536.7 kg ha was registered by CO (R) 50 with an increase of 19.2 per cent under the treatment of 1MCP (20 ppm) over other treatments and genotypes. To conclude, foliar application of 1MCP (20 ppm) and 6-Benzylaminopurine (30 ppm) at pre-anthesis and post anthesis stage to suppress ethylene production further strengthened the grain sink strength of inferior spikelets at same time development of more number of cells in endosperm by synthetic cytokinin (BAP) thereby registered better grain filling process and yield components in the rice genotype CO (R) 50.
Impact of elevated temperature and carbon dioxide on seed production of heat tolerant maize RCRMH-2

In scenario of global climate changes, air temperature may increase between 1.4 5.8 C and atmospheric carbon dioxide (CO2) concentration is predicted to rise from today’s value of current 370–550 ppm by 2050 and could reach between 730 and 1010 ppm by 2100. These changes may increase the frequency of extremes, including drought conditions, which will have significant consequences for crop growth and seed production in the future. An investigation was carried out to study the response of elevated carbon dioxide and temperature regimes on seed production of heat tolerant maize RCRMH-2 under Open Top Chamber (OTC’s) at Centre for Agro-climatic studies, University of Agricultural Sciences, Raichur, Karnataka during summer season 2019 and 2020. Morphological parameters and pysiological parameter indicated that, maize can be positively affected by CO2 enrichment and temperature regime, in part, because of improved water relations. The exposure of the crop elevated CO2 and temperature regime resulted in all the treatments the temperature was more than the threshold temperature (35 °C mean) during the reproductive stage. This might lead to pollen abortion. Also the silk might have dried at in this temperature and relative humidity leads to non seed setting in all the treatments. The results indicated that in summer season (Jan-May) maize exposed to elevated temperature affects the flowering stage during the months of March and April results in wilting, leaf firing and tassel blast leads to non availability of pollen grains for seed set.
A Comparative Study for the Effectiveness of Chemiluminescence and Toluidine Blue in the Early Detection of Oral Cancers

Purpose: This study aimed at comparing the efficacy of chemiluminescence and toluidine blue in detecting oral dysplasias and malignancies in at an early stage. Material and methods: A total of 26 patients who had potentially malignant lesions were included in the current study. All lesions were examined using Vizilite TM chemiluminescence followed by painting them with toluidine blue biostain. Then, all lesions were biopsied to be the gold standard for assessing both the chemiluminescence and the toluidine blue. Results: The current study showed low sensitivity, but high specificity and positive predictive value of TB (57.15%, 60%, and 85.71% respectively). On contrary, were the results of Vizilite (85.71%, 25%, and 57.14% on order). Conclusion: Although biopsy is the gold standard to detect dysplasia, toluidine blue and Vizilite were valuable non-invasive and rapid adjunct techniques that aided in the clinical detection and screening of dysplasia. They might have a special value in the screening for the existence of new lesions in patients with previous oral malignancies.
