High density polyethylene/wood flour composite: Optimization of processing temperature, processing time and coupling agent concentration

Wood plastic composites (WPCs) consisting of high density polyethylene (HDPE) reinforced with high-loading (55 wt%) of wood flour (WF) were fabricated with melt-blending technique. In this compounding method, processing parameters such as different mixing temperatures (of 165, 180 and 195°C), mixing times (of 5, 10 and 15 minutes) and coupling agent contents (of 2 and 4 wt%) were evaluated. Prepared specimens were analyzed with tensile, Izod, shore D, DMTA, short-term creep, DSC, TGA, water absorption and water contact angle characterizations. Results revealed that mixing temperature of 180°C, mixing time of 10 minutes and coupling agent concentration of 4 wt% were found as the best processing conditions. The mentioned conditions provided enhanced dispersion of WF particles within the HDPE matrix, due to optimum viscosity of the polymer melt and effective residence time of compound in the mixer, and beside them efficient interfacial adhesion between WF and polymer matrix.

Vegetative anatomy of three potted Chrysanthemum varieties under various paclobutrazol concentrations

Abstract. Lailaty IQ, Nugroho LH. 2021. Vegetative anatomy of three potted Chrysanthemum varieties under various paclobutrazol concentrations. Biodiversitas 22: 563-570. Chrysanthemum is one ornamental plant with high potential to be developed commercially. It has many varieties such as colors, types, and shapes of flowers. Paclobutrazol (PBZ) is one of plant growth regulators used to suppress plant growth. The PBZ action mechanism is to inhibit gibberellin synthesis. The application of PBZ with a certain concentration on Chrysanthemum plants has the potential to form potted Chrysanthemum. The aim of this study was to analyze the anatomical variation of potted mums varieties, i.e. Jaguar Red, Snow White and Fiji White, and also the effect of PBZ with various concentrations on the anatomy of the stems and leaves of three Chrysanthemum varieties. The research was conducted by applying PBZ concentrations of 0, 50, 100, 150 ppm to the three Chrysanthemum varieties and grown for 8 weeks to form potted Mums. Then, the anatomy of stems and leaves was studied using the paraffin and freehand section methods. Data analysis was performed using ANOVA and DMRT (Duncan Multiple Range Test) for anatomical characters in stems and leaves of three Chrysanthemum varieties. The results showed that the length of the epidermal cells of Fiji white variety was longer than those of Snow White and Jaguar Red. Meanwhile, Jaguar Red produced greater stem thickness, stomata, and leaf thickness than those of the other two varieties. PBZ could increase the size of the anatomical parameters of Chrysanthemum stems and leaves for all varieties. The PBZ concentration of 150 ppm increased leaf thickness and stem diameter, as well as tracheal diameter. The PBZ concentration of 100 ppm increased the size of the guard cells, palisade and spongy tissue, also peripheral tissues. Meanwhile, the PBZ concentration of 50 ppm had an effect on the increase in the number of stomata and pith diameter. The optimum PBZ concentration to form potted Chrysanthemum was 150 ppm.
Effects of vitamin E, an oil blend and L-Arginine on breast meat from broiler chickens

The study examined the effects of supplementing vitamin E on the fatty acid profile and breast meat quality of broilers fed diets containing an oil blend and L-Arginine. Two hundred sixteen Cobb 500 one-day-old broilers were randomly allocated to six treatments, namely T1: 6% palm oil (control); T2: blend of 4% palm oil and 2% sunflower oil + 0.25% L-Arginine (positive control); T3: T2 with 20 mg/kg vitamin E added; T4: T2 with 50 mg/kg vitamin E added; T5: T2 with 100 mg/kg vitamin E added; and T6: T2 supplemented with 150 mg/kg vitamin E. Relative to T1, the other diets increased growth rate and improved feed conversion ratio (FCR) similarly. Linoleic, arachidonic, and polyunsaturated fatty acids were greater and palmitic and saturated fatty acids were lower in the meat of birds fed T2–T6 relative to T1. Supplementation of vitamin E reduced drip loss (DL) and increased redness, tenderness, free thiol content, and the oxidative stability of meat during storage at 4 °C. Regardless of diet, free thiol, redness and Warner-Bratzler shear force (WBSF) value decreased significantly, whereas the carbonyl content, thiobarbituric acid-reactive substances (TBARS), and DL of breast meat increased over the ageing period. In conclusion, relative to T1, the other diets were effective in improving growth performance and meat quality during post-mortem storage Key words: fatty acid profile, free thiol, lipid oxidation, palm oil, protein oxidation, sunflower oil
Do Online Voter Guides Empower Citizens?

Abstract Voting Advice Applications (VAAs), which provide citizens with information on the party that best represents their political preferences, are often cited as evidence of the empowering capabilities of digital tools. Aside from the informational benefits of these voter guides, observational studies have suggested a strong effect on political participation and vote choice. However, existing impact evaluations have been limited by a reliance on convenience samples, lack of random assignment, or both. This raises questions about self-selection and the precise mechanisms underlying how voters learn about politics. Here, we provide evidence from a field experiment with survey outcomes conducted with a sample of over 1,000 German citizens in the 2017 federal election campaign. Using linked panel survey and digital trace data combined with a randomized encouragement to complete a VAA, we assess respondents’ compliance with treatment and observe how the use of this tool affects political behavior, attitudes, media consumption, political knowledge, and even social media activity. Our findings reveal that the overwhelming consensus in favor of positive effects on turnout and vote choice should be treated with caution, as we find no such effects. Rather, the actual virtue of VAAs in a complex online information environment lies in increasing knowledge about parties’ positions on issues—exactly the kind of information these tools were designed to provide.
Risk Factor of Hospital Malnutrition After Pediatric Nutrition Care Management

Increased prevalence of Hospital Malnutrition (HM) caused by Pediatric Nutrition Care (PNC) has not been implemented and influenced by several risk factors. The aim was to determine the prevalence and risk factors for gender, age, initial nutritional status, admission diagnosis, and length of stay (LOS) of HM after PNC. A cross sectional study was conducted from May 1, 2017 to May 1, 2018 by reviewing the medical record of children who were treated in the pediatric ward Dr. Soetomo Surabaya. The sampling method is total sampling. Hospital malnutrition was defined as weight loss ≥ 2% for LOS <7 days, ≥5% for 7-30 days and ≥ 10% for 1-6 months. Logistic regression was performed, and significance value with p <0.05. There were 736 children who met the inclusion and exclusion criteria. The prevalence of HM after PNC occurred in 5.6% children, which were dominated by 51.2% girls, 73.2% aged 1 month to 5 years, 46.3% well nourished, 61% from respiratory division, and 51.2% with LOS 7 to 30 days. Significant risk factors only from respiratory division (p = 0.033; OR 3.822; CI 95% 1.111-13.146). We conclude that children with admission diagnosis of respiratory division have a risk of HM after PNC. Keywords: prevalence; hospital malnutrition; pediatric nutrition care; risk factors; children
Incidence of Sucking Insect Pests on Cotton Plants Based on the Weather

Seasonal abundance of the sucking insect pests particularly the aphid and jassid on the cotton Gossypium hirsutum varieties CB12, CB13, CB14, CB15 and HC1, which are being cultivated in different Cotton Research and Multiplication Farms of Bangladesh, were studied from July 2018 to January 2019 at Gazipur in Bangladesh. The study also investigated the impact of weather parameters on the incidence of the pests. Aphids showed their abundance from the second week of October to the third week of November and the population revealed fluctuation. Aphid population reached to the peak in the fourth week of October (31.2/leaf) on HC1 followed by CB14, CB12, CB15 and CB13 cotton varieties. The weather factors collectively predicted 79.5% to 84.6% contribution on the abundance of aphid, and the highest and lowest effects were found on the varieties HC1 and CB14, respectively. Jassids showed their abundance from the first week of November to the second week of January and reached to the peak (7.2 leaf) in the fourth week of November on CB15 followed by CB12, CB13, HC1 and CB14 cotton varieties. The combination effect of the weather factors ranged from 57.4% to 71.0% abundances of jassid and the highest and lowest results were found on HC1 and CB15 varieties, respectively.

Application of Taguchi and ANOVA methods in the optimisation of a direct evaporative cooling pad

ABSTRACT The evaporative cooling pad system permits to cool buildings with less consumption of the electricity and without any use of refrigerant gases. A good evaporative cooling pad system must have a higher coefficient of performance and a lower rate of water consumption. In this study, the Taguchi method is used to investigate the effect of the velocity, the thickness of the pad, and the type of pads on the performances of cellulosic cooling pads. It was found that the velocity has more influence on the coefficient of performance and the water consumption while the pad thickness is the more significant parameter on the outlet temperature. For the three indicators, the best combinations of the influencing parameters are identified. The obtained results are confirmed by ANOVA analysis, and for fast sizing of the considered cooling pads, a regression model was presented for the aforementioned performance indicators.
Correlation of Ultrasound and Computed Tomography Measurements of the Pancreas in a Normal Adult Nigerian Population

Background Abdominal ultrasound and computed tomography (CT) utilization in pancreatic imaging has been found invaluable in the evaluation of pancreatic lesions. Although the gold standard modality for imaging of pancreas, CT is fraught with the limitations of radiation risk, cost and availability. Ultrasound (US) imaging of the pancreas is cost effective, readily available with no radiation risk but it is operator-dependent and limited by bowel gas. Comparative study of CT and US biometry of pancreas in normal adult population in Lagos State Nigeria has not been established. Method A prospective cross-sectional study of 150 apparently normal adult patients who underwent both CT scan and ultrasonography (US) at Clinix Healthcare Ilupeju, Lagos State, and who met the inclusion criteria, was carried out. Anterior-posterior (AP) dimensions of the pancreatic head, body and tail were obtained at right angles to the longitudinal axis of the organ. Results On US, the mean AP dimensions of the pancreas head, body, and tail in the studied population were 25.10 ± 2.75 mm, 15.98 ± 1.86 mm, and 13.50 ± 1.53mm respectively. On CT, the mean ± SD AP pancreas dimensions of head, body, and tail in the studied population were 26.77 ± 2.68 mm, 21.19 ± 2.12 mm, and 17.25 ± 2.12mm respectively. Conclusion AP dimensions of the pancreas segments measured on CT were significantly larger than that measured on US (P= 0.000), and CT is better modality in demonstration of pancreas segments especially the tail.
Hydroalcoholic extract of Arum orientale ameliorates myocardial infarction induced by isoproterenol in rats

: Arum species have antioxidant, antimicrobial, and anti-cancer effects. However, there is no study on its possible cardioprotective effects. In the present study, the protective effects of hydro-alcoholic extract of Arum orientale (A. orientale) on isoproterenol-induced myocardial infarction (MI) were evaluated. For induction of MI the rats were received isoproterenol (100 mg/kg) for two consecutive days, whereas treated groups received 40, 80 and 160 mg/kg/day of hydroalcoholic extract of A.orientale intraperitoneally (ip) 20 min before each Isoproterenol injection. Isoproterenol-induced MI significantly increased myocardial necrosis and neutrophil infiltration. Histopathological analysis showed that A. orientale at dose of 160 mg/kg significantly reduced necrosis and neutrophil infiltration in the heart tissue (P< 0.046 and P<0.048, respectively). Induction of MI also increased myeloperoxidase (MPO) activity and peripheral neutrophil percent. While A. orientale similarly decreased MPO activity and peripheral neutrophils in blood (P<0.021 p<0.042 respectively) at dose of 160 mg/kg. Administration of the extract markedly decreased serum malondialdehyde level at dose of 80 mg/kg and creatine phosphokinase (CPK) activity with all doses. Our results for the first time reported potential cardioprotective effects of A. orientale that partially can be through suppression of inflammatory responses and reduction of lipid peroxidation following MI. However, any suggestions for potential use in MI needs further studies.
Maternal near miss: A single centric experience

Introduction : Investigating severe maternal morbidity (near-miss) is a newly recognized tool which helps to identify women at highest risk of maternal death and helps allocate resources especially in low income countries. Aims and Objectives: Methods: It was a retrospective study conducted at Santokba Durlabhji Memorial Hospital, Jaipur (India) during September 2017 to August 2018. The study population included near miss cases and maternal deaths. The WHO near miss criteria 2009 was followed including clinical, laboratory and management based criteria for case identification. Results : Out of 2805 deliveries, 98 were near miss cases and 5 maternal deaths during the study period. The maternal near miss incidence ratio was 35/1000 live births. Most cases were referred to at perinatal period. Amongst the near-miss cases sepsis (36.5%) was the most common cause followed by haemorrhage (22.5 %) and hypertension (22.2 %). 60% required direct ICU admission. Conclusion : Near miss/mortality is an important indicator of the health care system of any country. Stress should be more towards training and improving services at district level. There should be a good referral system and patients with antenatal complications should be referred with fetus in utero to have a better feto-maternal outcome. Availability of adequate amount of blood products at district level could change the outcome drastically.
Analyzing Operational Efficiency in Real Estate Companies: An Application of GM (1,1) and DEA Malmquist Model

Real estate management and its operation play a crucial role in supporting company operation. Going hand-in-hand with the rapid growth of companies, the real estate portfolio has expanded dramatically, attracting large numbers of domestic and foreign investors. This paper studied the top 12 real estate companies listed on Vietnam’s stock market to develop a method that combines the Grey methodology and the Data Envelopment Analysis (DEA) Malmquist model, intending to predict and evaluate their performances in two periods: 2015–2018 and 2019–2022. The proposed model considered three input factors, namely total assets, cost of sales, and cost of goods sold, and two output factors, namely total revenue and gross profit. Findings revealed that drastic efficiency changes in some companies should be observed at the beginning of the process, even if the technological efficiency in the period is stable. In the future period, most companies achieved relatively stable productivity. This study serves as a reference for policymakers and strategy makers by analyzing insights for the operational status of real estate businesses and providing an overview in the future toward sustainable development.
Large Summer Rainfall Events and Their Importance in Mitigating Droughts over the South Western Cape, South Africa

Although the south Western Cape receives most of its rainfall between May and September, there are substantial rainfall events in some summers. These events are of interest in themselves as well as for their possible role in mitigating the frequent winter droughts that the region suffers from. Most recently, greater Cape Town suffered a devastating drought during 2015–18 known as the Day Zero drought due to the high risk of urban areas running out of piped water supply. Estimated data from the city show that major dam levels in the south Western Cape increased more than 1% in some cases after large rainfall events (LREs) in the summer of 2018/19. This increase is significant as dam levels often decrease by several percent per month during the hot summer. In this study, LREs over the south Western Cape during the summer (October–March) are investigated together with dam level data. Most summer LREs result from atmospheric rivers (ARs) or cutoff lows (COLs). ARs have not been previously studied in the South African region except for one study for winter that showed they are responsible for almost all the heavy rainfall events in the Western Cape. Although COLs are most common in the transition months, they can also occur in midwinter and summer. COLs tend to last longer and cover larger areas than ARs, which typically yield relatively short bursts of intense rainfall mostly concentrated around greater Cape Town. After each summer LRE, average dam levels increase by up to 5%, suggesting they are very important for drought recovery. In particular, summer LREs following the anomalously dry winters of 1980, 1984, 2003, 2004, and 2015–18 played an important role in mitigating those droughts.

The purpose of this study is to develop a chemistry teaching guide (CTG) for electrolyte solution and redox reaction based on scientific inquiry and find out its quality through the assessment of high school chemistry teachers. The choice of electrolyte solution and redox reaction material because this material is material that is easily developed into a scientific inquiry-based activity. This is research and development (R&D). The CTG was assessed by high school chemistry teachers who had taught the material for at least 2 years. The quality of the results of development is reviewed from the 5 assessment components, namely content, presentation, language, implementation, and display. The results of this study are that CTG based on scientific inquiry has been developed. The quality of the CTG is Very Good in terms of the results of the chemistry teachers assessment. Thus, CTG is feasible to be used by teachers as a guide in learning electrolyte solution and redox reactions based on scientific inquiry.
Finite element modelling of plain and reinforced concrete specimens with the Kotsovos and Pavlovic material model, smeared crack approach and fine meshes

Modelling of concrete through 3 D constitutive material models is a challenging subject due to the numerous nonlinearities that occur during the monotonic and cyclic analysis of reinforced concrete structures. Additionally, the ultimate limit state modelling of plain concrete can lead to numerical instabilities given the lack of steel rebars that usually provide with the required tensile strength inducing numerical stability that is required during the nonlinear solution procedure. One of the commonly used 3 D concrete material models is that of the Kotsovos and Pavlovic, which until recently it was believed that when integrated with the smeared crack approach, it can only be used in combination with relatively larger in size finite elements. The objective of this study is to investigate into this misconception by developing different numerical models that foresee the use of fine meshes to simulate plain concrete and reinforced concrete specimens. For the needs of this research work, additional experiments were performed on cylindrical high strength concrete specimens that were used for additional validation purposes, whereas results on a reinforced concrete beam found in the international literature were used as well. A discussion on the numerical findings will be presented herein by comparing the different experimental data with the numerically predicted mechanical response of the under study concrete material model.
Accuracy of Automated Written Expression Curriculum-Based Measurement Scoring

We examined the extent to which automated written expression curriculum-based measurement (aWE-CBM) can be accurately used to computer score student writing samples for screening and progress monitoring. Students (n = 174) with learning difficulties in Grades 1 to 12 who received 1:1 academic tutoring through a community-based organization completed narrative writing samples in the fall and spring across two academic years. The samples were evaluated using four automated and hand-calculated WE-CBM scoring metrics. Results indicated automated and hand-calculated scores were highly correlated at all four timepoints for counts of total words written (rs = 1.00), words spelled correctly (rs = .99–1.00), correct word sequences (CWS; rs = .96–.97), and correct minus incorrect word sequences (CIWS; rs = .86–.92). For CWS and CIWS, however, automated scores systematically overestimated hand-calculated scores, with an unacceptable amount of error for CIWS for some types of decisions. These findings provide preliminary evidence that aWE-CBM can be used to efficiently score narrative writing samples, potentially improving the feasibility of implementing multi-tiered systems of support in which the written expression skills of large numbers of students are screened and monitored.
