Enhanced Activity of ATRP Fe Catalysts with Phosphines Containing Electron Donating Groups

Fe-based atom transfer radical polymerization (ATRP) of styrene (St) with various triarylphosphines containing electron donating methoxy groups was investigated. FeIIIBr3 in the presence of tris(2,4,6- trimethoxyphenyl)phosphine (TTMPP) provided faster ATRP of St than in the presence of tris(4-methoxyphenyl)phosphine (TMPP) and much faster than with triphenylphosphine (TPP) under identical conditions. ATRP of St was carried out with initial ratio of reagents: [St]:[EBiB]:[FeIIIBr3]:[TTMPP] = 200:1:1:2, in 50% (v/v) anisole at 100 °C (EBiB is ethyl 2-bromoisobutyrate). After 21 h, conversion reached 92%, yielding polystyrene with molecular weight Mn = 24 100 and Mw/Mn = 1.25. With TMPP and TPP under the same conditions, the conversion of monomer was only 19% and 9%, respectively. With 1 equiv of TTMPP vs FeIIIBr3, control was better, Mw/Mn ∼ 1.1, but polymerization was slower. The phosphines could directly reduce FeIII to FeII but could also act as ligands complexing transition metal and forming efficient .
A CROSS-SECTIONAL STUDY ON BACTERIOLOGICAL PROFILE AND ANTIBIOTIC SENSITIVITY PATTERNS OF MAXILLOFACIAL INFECTIONS

Introduction: Odontogenic infections are one of the most frequently occurring infectious processes. The current study was planned with the objective to determine the bacteriological prole and antibiotic sensitivity patterns of isolates from maxillofacial infections in patients without a history of empiric antibiotic therapy. Materials and methods:Patients suffering from various infections of the maxillofacial region were contacted. Patients were interviewed using a questionnaire and a sample was taken from abscess. Various lab investigations were also done. Results: A total of 82 patients with Maxillofacial infection were included. In this study, the most common clinical presentation was pain (90.24%) and swelling (70%). Mandibular teeth are involved in 71.95% of cases, and 28.05% of maxillary teeth are involved. The rst molar tooth was most associated with infection. (n = 54). On analysing various organisms causing infection, 28 (34.15%) of the infections were caused by aerobes, 11 (13.41%) by anaerobes, and 30 (36.58%) were of mixed. No pathogens were isolated in 13 (15.85%) of the patients. The most sensitive antibiotic was amoxicillin/clavulanate combination (84.05% sensitive), followed by Clindamycin (81.16% sensitive). Conclusion: Most of maxillofacial infection were caused by aerobes and most sensitive antibiotic was amoxicillin/clavulanate combination.
Pathological Complete Response to Neoadjuvant Chemotherapy in Patients With Breast Cancer: The Relationship Between Inflammatory Biomarkers and Molecular Subtypes

Purpose Among patients with breast cancer, pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) is an important prognostic predictor of survival. This study aimed to investigate the relationship between platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) along with overall pCR. Method A total of 150 patients with breast cancer who were first administered NAC and then operated on were retrospectively evaluated. Neutrophil-lymphocyte ratio and PLR obtained from the complete blood count analysis performed immediately before NAC treatment were analyzed. The cut-off value was calculated as 150 for PLR and 2.24 for NLR. We studied the predictive value of NLR and PLR levels for the pathologic response of breast cancer to NAC. Results Pathological complete response was observed in 34.7% (n = 52) of the patients, pCR in the breast in 42.7% (n = 64), and that in the axilla in 44% (n = 66). There was a statistically significant difference between the pCR rates according to the PLR levels (p = 0.013). In addition, a statistically significant difference was found in the pCR rates in the breast and axilla according to PLR levels (p = 0.018, p = 0.009). Patients with low PLR in the human epidermal growth factor receptor 2 (HER-2) group had significantly higher axillary pCR rates than in those with high PLR (p = 0.019). Conclusions A low PLR level showed high chemotherapy sensitivity independent of molecular subtypes in the treatment of breast cancer with NAC. The PLR level can serve as a predictive marker of the therapeutic effect of NAC on the breast and axilla. Low PLR levels in HER-2 enriched groups can predict pCR in the axilla.

QUARTERLY EARNINGS MANAGEMENT: THE ROLE OF AUDIT QUALITY

This paper used data of companies listed in United Arab Emirates stock markets from 2011 to 2019 to investigate whether the magnitude of quarterly earnings management varies across quarters. Additional tests were conducted to examine the effect of audit quality on the level of earnings management. Multivariate regression analysis was employed to test the sensitivity of earnings management to quarters and to audit quality. Overall, results indicate a higher level of earnings manipulation during the first and the fourth quarter. During the first quarters mangers might have a discretionary attitude to avoid losses or decline in earnings. A reversing effect was detected in the fourth quarter. Firms audited by a big 4 auditors are less likely to manage their earnings. High quality audit seems reducing the manipulation of earnings.
The use of Mosquito Nets and The Habit of Going Out at Night as Risk Factors for Filariasis in Kodi Balaghar sub-district, Southwest Sumba district, East Nusa Tenggara, Indonesia; Case Control Study

There is not much information about the risk factors for filariasis transmission in Southwest Sumba Regency, East Nusa Tenggara. To obtain this information, we conducted an epidemiological study of the incidence of filariasis infection in Kahale Village and Radda Malando Village, Balaghar District. The factors investigated were gender, age, occupation, occupancy density, knowledge, use of mosquito nets, nighttime habits, use of mosquito repellent, habit of hanging clothes in the room, physical condition of the house, proximity to mosquito breeding habitats and close to people with filariasis. This type of research is analytic observational where the sample was taken using case control as many as 64 people. The research instrument used a questionnaire and check list. Data analysis used the SPSS program statistical test with Backward Logistic Regression Test. The results of the bivariate test showed that the variables that had a relationship with the incidence of filariasis were the use of mosquito nets, the habit of going out at night, the habit of hanging clothes in the room with a p value <0.05. The prediction model for the incidence of filariasis with the ability to predict is 88.8% with the following equation: Y = -10,609 + 5,148 use of bed nets + 3,318 night out habits. The study showed that two variables were risk factors for filariasis, namely the habit of using a mosquito net (OR 172.18) and the habit of going out at night (OR 27.596). We conclude that the behavior of using bed nets and the habit of going out at night plays an important role in increasing filariasis infection so that it is important to change aspects of community behavior to reduce the incidence of filariasis infection.
TH1 VERSUS TH17 IN CHRONIC HEPATITIS C VIRUS INFECTION

Background: Hepatitis C virus (HCV) is a major cause of chronic liver disease affecting close to 170 million people worldwide. Egypt Demographic Health Surveys (EDHS) measured antibody prevalence among adult population aged 15-59 years at 14.7% in 2009 and at 10.0% in 2015. Approximately, 85% of patients acutely infected with HCV progress to chronic liver disease with persistence of HCV RNA for more than 6 months. Among patients with chronic HCV infection, 15-20% progress to end-stage liver disease and approximately 14% of these patients progress to cirrhosis or hepatocellular carcinoma with time. With hepatitis C, being a national care problem, predicting the outcome of treatment in these patients becomes very important. Objectives: The aim of this study was to evaluate and predict the response in hepatitis C virus patients to pegylated interferon alpha and ribavirin therapy in association with estimation of the percentage of TH1 and TH17 by flowcytometry. Patients and Methods: This study was conducted on 50 patients with proven chronic hepatitis C virus infection based on by PCR technique and histopathology (25 responders and 25 non-responders). All of them were treated by combined pegylated interferon alfa plus ribavirin orally. Patients with history of previous interferon therapy, evidence of other systemic illness including: (hepatic, renal, cardiac, diabetic and neoplastic disease), chronic inflammatory disease, unstable thyroid dysfunction, unstable psychiatric disorder or history of any organ transplantation were excluded. All patients were F2or F3 on fibroscan. By flowcytometry, human CD4 percentage was estimated by using fluorescein-conjugated antibody. Human TH17 percentage was estimated by using PerCP-conjugated antibody, and TH1 was estimated by phycoerythron conjugated antibody. Both TH1 and TH17 were performed at weeks 0 and retested again after 12 weeks. Results: After 12 weeks from starting of therapy, there was an increase in percentage of TH1 in nonresponders of therapy compared to responders with no difference in the percentage of TH17 between the two groups. Conclusion: There was a positive correlation between TH1 and TH17 in both groups before and after therapy. Also, we found that 98% of patients achieved sustained virological response 12 weeks after completion of therapy (SVR12) showed sustained virological response 24 weeks after completion of therapy (SVR24).
Case Report: The Impact of Online Forum Use on Student Retention in a Level 1 Distance Learning Module

The importance of making online and distance education successful has been dramatically prioritized due to the COVID-19 pandemic. Student retention is a key performance indicator in online higher education. Evidence suggests that within online distance education the key to retaining students is to encourage an engaging and supportive online community. Online asynchronous forums are one method that has been employed to promote such engagement. This study investigated the relationship between online forum activity and student retention amongst 21 tutor groups on an Open University Level 1 module. It found that the volume of tutor group forum activity had a significant association with student retention (p<0.05 two-tailed, Pearson r=0.53), with student contributions having a greater impact on retention (p<0.01 two-tailed, Pearson r=0.628) than tutor contributions. Although tutor contributions did not appear to impact student retention directly the number of tutor and student posts were highly correlated (p<0.001, two tailed, Pearson r=0.86). Results indicate that asynchronous forums can be an effective tool in promoting student retention in an online distance learning environment. Important factors that impact on student retention within the educational medium of asynchronous forums are evidenced. The implications of these findings for educators are discussed. Keywords: distance learning, student retention, forum participation, online learning community.
Reply on RC1

The focus of this paper is to evaluate the performance of RCNN-SVR method on water distribution networks. During the studies conducted by the authors, the use of RCNN-SVR was observed in some engineering sciences, but the ability of this method in estimating the failure rate of water network pipes (in real case study) has not been measured in any scientific article. Therefore, the present study shows the high accuracy of this innovative method. Researchers can use this method as an efficient method in their researches. On the other hand, there are several articles in high-credited scientific journals that have compared outdated conventional machine learning methods. In this paper the new method that has much higher accuracy and efficiency is applied.
Food irradiation: A review

Consumers expect that the food they eat must be safe. In addition, consumers also wants the food to have high nutritional value with minimal preparation times, as evidenced by the growth in products such as convenience ready to eat and minimally processed fresh produce. In order to meet these demands, food manufacturer are looking for new method and technologies. One such technology is irradiation. Irradiation is non-thermal food preservation technique which is used to extend and enhance the shelf life of fresh or processed foods. Food irradiation is an energy-efficient, non-chemical method of food processing that can help reduce those huge losses occurring due to spoilage or contamination by harmful bacteria and other parasitic life forms. It involves exposure of foods to ionizing radiations either prepackaged or in bulk to reduce the risk of foodborne illness, delaying or eliminating sprouting or ripening. Gamma rays, electron beams, and x-rays are used for irradiation of foods. Properly treated, irradiated foods retain their fresh appearance, flavour, and nutritional value, while most foods can be pre-packaged before irradiation, reducing the risk of re-contamination. The inactivation mechanism involves two processes either direct or indirect method. Ionizing radiations kills microbes directly by damaging biomolecules of cells. When incoming photons hit the microbes or food molecules, collisions occur, as a result, the microbes die. Irradiation doses can be generated using Cobalt-60 as an radiation source. Electron beams are propelled out of an electron gun with streams of high-energy electrons. Electron beam accelerators are used in X-ray facility to target electrons on metal plate. Exposure time depends upon the characteristics of food and the doses of irradiation. Irradiation dose is measured as gray (Gy). This is a measure of the amount of energy transferred to food, microbe or other substance being irradiated. The most commonly products used for irradiation are fresh fruits and vegetables (strawberry, mangoes, guava, tomato, potato, garlic etc, cereals and cereal products (wheat, rice, barley, flour etc).
Artificial bee colony based state feedback position controller for PMSM servo-drive – the efficiency analysis

This paper presents a state feedback controller (SFC) for position control of PMSM servo-drive. Firstly, a short review of the commonly used swarm-based optimization algorithms for tuning of SFC is presented. Then designing process of current control loop as well as of SFC with feedforward path is depicted. Next, coefficients of controller are tuned by using an artificial bee colony (ABC) optimization algorithm. Three of the most commonly applied tuning methods (i.e. linear-quadratic optimization, pole placement technique and direct selection of coefficients) are used and investigated in terms of positioning performance, disturbance compensation and robustness against plant parameter changes. Simulation analysis is supported by experimental tests conducted on laboratory stand with modern PMSM servo-drive.
Continuous diffusion spectrum computation for diffusion-weighted magnetic resonance imaging of the kidney tubule system.

Background The use of rigid multi-exponential models (with a priori predefined numbers of components) is common practice for diffusion-weighted MRI (DWI) analysis of the kidney. This approach may not accurately reflect renal microstructure, as the data are forced to conform to the a priori assumptions of simplified models. This work examines the feasibility of less constrained, data-driven non-negative least squares (NNLS) continuum modelling for DWI of the kidney tubule system in simulations that include emulations of pathophysiological conditions. Methods Non-linear least squares (LS) fitting was used as reference for the simulations. For performance assessment, a threshold of 5% or 10% for the mean absolute percentage error (MAPE) of NNLS and LS results was used. As ground truth, a tri-exponential model using defined volume fractions and diffusion coefficients for each renal compartment (tubule system: Dtubules , ftubules ; renal tissue: Dtissue , ftissue ; renal blood: Dblood , fblood ;) was applied. The impact of: (I) signal-to-noise ratio (SNR) =40-1,000, (II) number of b-values (n=10-50), (III) diffusion weighting (b-rangesmall =0-800 up to b-rangelarge =0-2,180 s/mm2), and (IV) fixation of the diffusion coefficients Dtissue and Dblood was examined. NNLS was evaluated for baseline and pathophysiological conditions, namely increased tubular volume fraction (ITV) and renal fibrosis (10%: grade I, mild) and 30% (grade II, moderate). Results NNLS showed the same high degree of reliability as the non-linear LS. MAPE of the tubular volume fraction (ftubules ) decreased with increasing SNR. Increasing the number of b-values was beneficial for ftubules precision. Using the b-rangelarge led to a decrease in MAPE ftubules compared to b-rangesmall. The use of a medium b-value range of b=0-1,380 s/mm2 improved ftubules precision, and further bmax increases beyond this range yielded diminishing improvements. Fixing Dblood and Dtissue significantly reduced MAPE ftubules and provided near perfect distinction between baseline and ITV conditions. Without constraining the number of renal compartments in advance, NNLS was able to detect the (fourth) fibrotic compartment, to differentiate it from the other three diffusion components, and to distinguish between 10% vs. 30% fibrosis. Conclusions This work demonstrates the feasibility of NNLS modelling for DWI of the kidney tubule system and shows its potential for examining diffusion compartments associated with renal pathophysiology including ITV fraction and different degrees of fibrosis.
Potential changes in the distribution of Delphinium bolosii and related taxa of the series Fissa from the Iberian Peninsula under future climate change scenarios

A particular threat posed by climate change for biodiversity conservation, one which has scarcely been studied, is the overlap of the potential distribution areas in phylogenetically closely related species. In this study, Species Distribution Modelling (SDM) was used to investigate the potential changes in the distribution of Delphinium bolosii and D. fissum subsp. sordidum under future climatic scenarios. These two closely related and endangered endemic species from the Iberian Peninsula do not have complete reproductive barriers between them. The two models selected different predictors with a similar effect in the biological cycle. Both taxa need low winter temperatures to break seed dormancy and sufficient rainfall to complete the flowering and fruiting stages. The current potential distribution areas of both taxa do not currently overlap. However, the results showed that potential changes may take place in the species’ distribution range under future climate scenarios. The models predict a reduction of the potential distribution area of D. bolosii while, conversely, the potential distribution area of D. fissum subsp. sordidum increased. In both cases, the predicted contraction in range is very high, and loss of habitat suitability in some current localities is worrying. Notwithstanding, the models do not predict overlaps of potential areas under climate change scenarios. Our findings can be used to define areas and populations of high priority for conservation or to take action against the impacts of climate change on these endangered species.
