Published: August 2020

<p>We can identify human faces using a web Camera which is known as Face Detection. This is a very effective technique in computer technology. There are used different types of attendance systems such as log in with the password, punch card, fingerprint, etc. In this research, we have introduced a facial recognition type of biometric system that can identify a specific face by analyzing and comparing patterns of a digital image. This system is the latest login system based on face detection. Primarily, the device captures the face images and stores the captured images into the specific path of the computer relating the information into a database. When any body tries to enter into any room or premises through this login system, the system captures the image of that particular person and matches the image with the stored image. If this image matches with the stored image then the system allows the person to enter the room or premises, otherwise the system denies entry. This face recognition login system is very effective, reliable and secured. This research has used the Viola and Jones algorithm for face detection and ORB for image matching in face recognition and Java, MySql, OpenCV, and iReport are used for implementation.</p>

Published: August 2020

O Granito Itapuranga localiza-se na porção central da Faixa Brasília, exibe formato alongado na direção E-W e está associado ao Lineamento dos Pirineus. Apresenta textura porfirítica em diferentes estágios deformacionais (protomilonito a ultramilonito), com mineralogia constituída de fenocristais de feldspato potássico em matriz quartzo-feldspática, associado a biotita e anfibólio, além de titanita, epídoto e zircão como minerais acessórios. Os dados geoquímicos revelam composição subalcalina de alto-K (shoshonítica) e metaluninosa, variando de quartzo sienito a sienogranito e monzogranito. As idades TDM Sm-Nd variam de 1,27 a 1,91 Ga com valores εNd(0) = -11 a -15, sugerindo fonte crustal mais antiga (Paleo a Mesoproterozoico). Esse magmatismo possui assinatura geoquímica do tipo-I e envolve processo de fracionamento, provavelmente de ambiente tardi-orogênico a pós-colisional. Os dados obtidos indicam que o Granito Itapuranga foi originado a partir da fusão parcial de uma crosta paleoproterozoica, interagindo com manto litosférico heterogêneo metassomatizado durante processo de subducção. Para essas interpretações, associa-se uma importante contribuição de fontes astenosféricas ligadas à colisão do Arco Magmático de Goiás a partir da fusão do manto por descompressão adiabática.
Microanalytical techniques for phenotyping secondary xylem

Published: August 2020

Abstract
The products of secondary xylem are of significant biological and commercial importance, and as a result, the biology of secondary growth and how intrinsic and extrinsic factors influence this process have been the subject of intense investigation. Studies into secondary xylem range in scale from the cellular to the forest stand level, with phenotypic analyses often involving the assessment of traits relating to cell morphology and cell wall chemical composition. While numerous techniques are currently available for phenotypic analyses of samples containing abundant amounts of secondary tissue, only a few of them (microanalytical techniques) are suitable when working with limiting amounts of secondary tissue or where a fine-scale resolution of morphological features or cell wall chemical composition is required. While polarised light microscopy, scanning electron microscopy, field emission-scanning electron microscopy and X-ray scattering and micro-tomography techniques serve as the most frequently used microanalytical techniques in morphotyping, techniques such as scanning ultraviolet microspectrophotometry, X-ray photoelectron spectroscopy, gas chromatography, Fourier-transform infrared spectroscopy and matrix-assisted laser desorption ionisation mass spectrometry serve as the most commonly used microanalytical techniques in chemotyping. Light microscopy, fluorescence microscopy, confocal laser scanning microscopy, transmission electron microscopy and Raman spectroscopy serve as dual micro morphotyping and chemotyping techniques. In this review, we summarise and discuss these techniques in the light of their applicability as microanalytical techniques to study secondary xylem.
Heavy Daily Precipitation Events in the CMIP6 Worst-Case Scenario: Projected Twenty-First-Century Changes
Authors: Scoccimarro Enrico , Gualdi Silvio 
Published: August 2020

AbstractHeavy precipitation is often the trigger for flooding and landslides, leading to significant societal and economic impacts, ranging from fatalities to damage to infrastructure to loss of crops and livestock. Therefore, it is critical that we have a better understanding of how it may be changing in the future. Based on model projections from phases 3 and 5 of the Coupled Model Intercomparison Project (CMIP3 and CMIP5), future daily precipitation is likely to increase in intensity. The main goal of this study is to examine possible improvements in the representation of intense and extreme precipitation by a new set of climate models contributing to phase 6 of CMIP effort (CMIP6) and to quantify its projected changes under the highest emissions scenario by the end of the current century [i.e., Shared Socioeconomic Pathway (SSP) SSP5-8.5]. Daily precipitation data from six CMIP6 models were analyzed that have a nominal horizontal grid spacing around 100 km and provide data for the highest emissions scenario SSP5-8.5. Two of the six CMIP6 models overestimate the extreme precipitation (defined as the 99th percentile of the precipitation distribution) in the tropics, leading to large biases in the right tail of the daily precipitation over the tropics. Consistent with the CMIP5 results, the CMIP6 models projected increased heavy daily precipitation and increased width of the right tail of the precipitation distribution associated with increased water vapor content.

AbstractThis work details a master oscillator power amplifier (MOPA) microjoule-class pulsed coherent Doppler lidar system configuration designed to measure line-of-sight wind velocities and backscatter intensity of atmospheric aerosols. The instrument is unique in its form factor. It consists of two physically separated modules connected by a 10 m umbilical cable. One module hosts the transceiver, which is composed of the telescope, transmit/receive (T/R) switch, and high-gain optical amplifier, and is housed in a small box (34.3 cm × 34.3 cm × 17.8 cm). The second module contains the data acquisition system and several electro-optical components. This form factor enables deployments on platforms that are otherwise inaccessible by commercial and research instruments of similar design. In this work, optical, electrical, and data acquisition components and configurations of the lidar are detailed and two example deployments are presented. The first deployment describes measurements of a controlled wildfire burn from a small aircraft to measure vertical plume dynamics and fire inflow conditions during summer in Florida. The second presents measurements of the marine boundary layer height and vertical velocity and variance profiles from the Research Vessel (R/V) Thomas Thompson. The new instrument has enabled greater flexibility in field campaigns where previous instruments would have been too costly or space prohibitive to deploy.

Objectives(1) To measure caregiver satisfaction with a nonstandardized postoperative pain regimen after pediatric tonsillectomy. (2) To implement a quality improvement project (QIP) to reduce the number and volume of narcotics prescribed and to describe the effect on caregiver satisfaction.MethodsA prospective cohort study at a tertiary children’s hospital examined postoperative narcotics prescribed to children following adenotonsillectomy. A QIP was implemented 3 months into the observation, with the goal to standardize nonnarcotic analgesics and reduce the volume of narcotics prescribed. Caregivers were called 2 to 3 weeks postoperatively to assess pain control and caregiver satisfaction.ResultsOver an 8‐month period, 118 patients were recruited (66 before the QIP, 52 after induction). Prior to the QIP, 47% of patients were prescribed postoperative narcotics, as opposed to 27% after the QIP (P <. 05). There was a significant reduction in the volume of narcotics prescribed before (mean ± SD, 300 ± 150 mL) versus after (180 ± 111 mL) the initiative (P <. 05). The per‐kilogram dose did not change over the study time frame. On a 5‐point Likert scale, there was no difference in the caregivers’ satisfaction regarding pain control before (4.37 ± 0.85) versus after (4.35 ± 1.0) the project started.DiscussionA system shift was identified with the establishment of a posttonsillectomy pain control protocol associated with a reduction in prescribed narcotics without a significant change in caregiver satisfaction.Implications for PracticeImplementing a standardized plan for the use of nonnarcotic medications was associated with reduced frequency and volume of narcotics prescribed. Future work will further standardize our postoperative pain regimen.

ObjectiveTo determine the significance and impact of additional chloride testing as part of a diagnostic laboratory test battery for borderline primary hyperparathyroidism (pHPT).Study DesignRetrospective database review of parathyroidectomy patients.SettingA tertiary care, academic health sciences center.Subjects and MethodsPatients referred to a head and neck endocrine clinic for evaluation and treatment for pHPT.ResultsAfter exclusions, there were a total of 226 patients who underwent parathyroidectomy for primary hyperparathyroidism with the requisite preoperative and postoperative labs. Seventy‐seven additional patients who had a thyroid operation for a nonmalignant cause were included as controls. Of the 303 total patients, 166 had normal calcium levels (<10.4 mg/dL), and 54 (32.5%) also exhibited hyperchloremia (>106 mmol/L). Of the 47 patients with normal calcium and parathyroid hormone (PTH) levels (<88 pg/mL), 6 (12.8%) had hyperchloremia, and of the 118 patients with normocalcemic pHPT, 48 (40.7%) were hyperchloremic. The area under the curve for the Cl:PO4 was 0.712. When using a cutoff of 33, the reported sensitivity and specificity of the curve were 58.4% and 28.6%, respectively.ConclusionThe Cl:PO4 ratio was a moderately sensitive test for the diagnosis of the borderline variants of primary hyperparathyroidism. The Ca:PO4 ratio was superior to the Cl:PO4 ratio. Our data also showed the superiority of preoperative calcium and ionized calcium over PTH when predicting the presence of pHPT.

ObjectivesTo evaluate the accuracy of methylene blue (MB) for diagnosing oral cancer and precancer.Data SourcesPubMed, Cochrane Database, Embase, Web of Science, SCOPUS, and Google Scholar.Review MethodsTwo authors working independently reviewed 6 databases from their dates of inception until April 2020. Studies exploring oral mucosal disorders as detected by MB were assessed. True‐positive, true‐negative, false‐positive, and false‐negative data were extracted for each study. Methodological quality was evaluated with the Quality Assessment of Diagnostic Accuracy Studies tool (v 2).ResultsSeven prospective and retrospective studies (N = 493) were included. The diagnostic odds ratio of MB was 20.017 (95% CI, 10.65‐37.63, I2 = 23%). The area under the summary receiver operating characteristic curve was 0.699. Sensitivity was 0.903 (95% CI, 0.84‐0.94, I2 = 54%), and specificity was 0.68 (95% CI, 0.60‐0.75, I2 = 0%). The correlation between the sensitivity and the false‐positive rate was –0.17, indicating an absence of heterogeneity.ConclusionsRegarding diagnostic accuracy, MB had high sensitivity but low specificity, suggesting that it cannot be recommended as a replacement for the currently used standard of a scalpel biopsy with histologic assessment. Instead, it should be used as an adjunct to conventional assessment because of its low toxicity and price.
Performance of Odisha State Co-operative Bank: An ARDL Approach
Authors: Nayak Ranjan Kumar 
Published: August 2020

This article tries to analyse the financial performance of Odisha State Co-operative Bank (OSCB) for the period of 1949–1950 to 2014–2015. The methodology employed for the empirical analysis on this study involves autoregressive distributed lag (ARDL), augmented Dickey–Fuller (ADF) test and Phillips–Perron (PP). Statistical significant of the coefficient of the lagged error-correction term shows about 44 per cent correction in short-run dynamics to the long-run equilibrium. Using the ARDL approach, the study finds that owned fund, borrowing, advance and working capital, share capital and reserve are statistically significant in the short run; and deposits, share capital and reserve are statistically significant in the long run. The empirical results suggest that deposits and advances impact the profits of OSCB positively while cost of management, capital and reserves lead to lower profits. Hence, the study proposes the OSCB to follow a proactive management of capital with higher deposit generation and larger advances strategy to become a strong bank and grow steadily. JEL: C01, C1

Published: August 2020

Introduction Cancer patients tend to prefer oral instead of parenteral chemotherapy. To date, there is little evidence on the medication adherence in cancer patients. We investigated medication adherence to tyrosine kinase inhibitors in patients suffering from non-small cell lung cancer. Methods Tyrosine kinase inhibitor adherence was measured electronically by MEMS® (medication event monitoring system) over at least six months. Adherence rates were calculated in terms of Dosing Compliance, Timing Compliance, Taking Compliance, and Drug Holidays. Patients were dichotomized as adherent when Dosing Compliance and Timing Compliance were ≥80%, Taking Compliance ranged between 90 and 110%, and <1 Drug Holiday was registered. Quality of life was assessed by two questionnaires (EORTC QLQ-C30 version 3.0, EORTC QLQ-LC13) at three time points. Adverse drug events were reported via patient diaries. Results Out of 32 patients enrolled, data from 23 patients were evaluable. Median Dosing Compliance, Taking Compliance, and Timing Compliance adherence rates of tyrosine kinase inhibitor intake amounted to 100%, 98%, and 99%, respectively; Drug Holidays were observed in three patients. Four patients were dichotomized as non-adherent. Three of them had a twice-daily tyrosine kinase inhibitor regimen. Median quality of life scores amounted to 67 (max. 100) and remained unchanged over the study period. Fatigue and rash were the most frequently reported adverse drug events. Conclusion Medication adherence of non-small cell lung cancer patients treated with tyrosine kinase inhibitors was extraordinarily high and is likely to support the effectiveness of tyrosine kinase inhibitor treatment and a good quality of life over a long period of time. Adherence facilitating information and education is especially relevant for patients taking tyrosine kinase inhibitors in a twice-daily regimen.

Introduction: Revision total hip arthroplasty (rTHA) is becoming a more common procedure due to the increasing volume of primary total hip arthroplasty. Diabetes mellitus (DM) is currently projected to affect 4.4% of the global population by 2030. Diabetes has been associated with poor outcomes for a variety of surgical interventions. However, the impact of insulin dependence has yet to be fully understood. The aim of this study was to determine the impact of insulin dependence on acute postoperative complications following rTHA. Methods: A retrospective cohort study was conducted using the American College of Surgeons National Quality Improvement Program database. All patients who underwent rTHA between 2006 and 2016 were identified and recorded as having non-insulin-dependent DM (NIDDM), insulin-dependent DM (IDDM) or no DM. Univariate and multivariate analysis were used to evaluate the incidence of multiple adverse events within 30 days after rTHA. Results: A total of 7685 patients were evaluated (No DM = 6651, NIDDM = 700, IDDM = 334). Univariate analysis revealed that all patients with DM had significantly higher incidences of postoperative complications (NIDDM: p < 0.001; IDDM: p < 0.001) and extended hospital length of stay (NIDDM: p = 0.015; IDDM: p < 0.0001). NIDDM was associated with increased rates of superficial surgical site infection (SSI) ( p = 0.001), deep SSI ( p = 0.038), and stroke ( p = 0.013), while IDDM was associated with increased rates of pneumonia ( p < 0.001), renal failure ( p < 0.001), and postoperative transfusion ( p < 0.001). On multivariate analysis, insulin-dependence was determined to be an independent risk factor for extended hospital length of stay (OR 1.905; 95% CI, 1.410–2.577; p < 0.001), pneumonia (OR 4.016; 95% CI, 1.799–8.929; p = 0.001), renal failure (OR 7.143; 95% CI, 2.203–23.256; p = 0.001) and postoperative transfusion (OR 1.366; 95% CI, 1.076–1.733; p = 0.01). Conclusions: Insulin dependence is an independent risk factor for numerous short-term postoperative complications following rTHA. When assessing risk and planning perioperative management, surgeons should consider insulin-dependent diabetics as a sub-cohort within the diabetic population.

Background: Achieving access to clean water and basic sanitation remains as major challenges in Vietnam, especially for vulnerable groups such as minority people, despite all the progress made by the Millennium Development Goal number 7.C. Objectives: The study aimed to describe the access to improved water sources and sanitation of the ethnic minority people in Vietnam based on a national survey and to identify associated factors. Methods: A cross-sectional study was conducted in 2019 with a sample size of 1385 ethnic minority households in 12 provinces in Vietnam. Multivariate logistic regression modeling was performed to examine the probability of having access to improved water sources and sanitation and sociodemographic status at a significance level of P < .05. Results: The access to improved water sources and sanitation was unequal among the ethnic minority people in Vietnam, with the lowest access rate in the northern midland and mountainous and Central Highland areas and the highest access rate in the Mekong Delta region. Some sociodemographic variables that were likely to increase the ethnic minority people’s access to improved water sources and/or sanitation included older age, female household heads, household heads with high educational levels, religious households, and households in not poor status. Conclusion and recommendations: The study suggested more emphasis on religion for improving the ethnic minority’s access to improved water sources and sanitation. Besides, persons of poor and near-poor status and with low educational levels should be of focus in future water and sanitation intervention programs.
