Changes in satellite-based cloud parameters in the Baltic Sea region during spring and summer (1982–2015)

Abstract. The satellite-based cloud climate data record CLARA-A2 has been used to analyse regional average time-series and regional maps of trends in the Baltic Sea region, 1982–2015. The investigated cloud parameters were total fractional cloud cover and cloud top height. Cloud observations from the Tartu-Toravere meteorological station were used as reference data for the same period. Fractional cloud cover from CLARA-A2 was in a good agreement with in situ data regarding the maxima and minima years and a downward trend in March over the 1982–2015 period. In June the fractional cloud cover interannual variability was very high and no clear trend was seen. For cloud top heights summer and spring regional averages showed opposite signs of the trend: for June positive and for March negative. Winter and autumn seasons have been left out of analysis due to too large uncertainties in cloud products over latitudes higher than 60 ∘ .
Portulaca Oleracea Leaves in Broiler Diets: Effect on Chicken Performance and Health

Background: Portulaca oleracea L. which is commonly called purslane is a herbaceous weed that is widely distributed throughout the world. Purslane is listed in the World Health Organization as one oaf the most used medicinal plants. The purslane is the richest vegetable sources of omega-3 fatty acids, flavonoids (kaempferol, quercetin and apigenin), vitamins A, C, E and minerals. To study the impact of using Portulaca oleracea in boiler diet on performance and health of chicken. Method: Chemical composition of Portulaca oleracea leaves was performed, then five iso-nitrogenous and iso-caloric experimental broiler diets were formulated as MOL0%, POL5%, POL10%, POL15% and POL20%, respectively and supplemented to broilers (10 chicks in each concentration) for 42 day. After 42nd day. Results: The chemical composition of Portulaca oleracea leaves showed average proportions of crude fiber, crude lipids, crude protein, total sugars, reducing sugar and non-reducing sugars. The highest effect of supplementation of Portulaca oleracea poultry diets on body weight of broiler, was 2024, 2112 and 2341gm, of treatments (10, 15 and 20% of POL), respectively. Also, the more effective treatment was 20% of POL of blood biochemical, lipid profile, Liver function and haematological parameters, comparing with normal diets.
University students’ negative emotions in a computer-based examination: the roles of trait test-emotion, prior test-taking methods and gender

Abstract Although the effectiveness and experiences of computer-based examinations is a widely investigated area of research, the question of whether and how computer-based assessment limits or heightens the experience of negative test emotions remains largely unexamined. Drawing from the control-value theory of achievement emotions, we investigated undergraduate students’ emotions during an authentic, course-based assessment in a computer-based testing environment, as well as predictors and outcomes associated with their emotions. We found that students (N = 74) in a computer-based testing environment reported lower levels of negative emotions than their typical negative test emotions. Females and males performed equally in the examination, yet females reported higher retrospective negative emotions. Consistently, females reported higher levels of typical test-taking anxiety in prior examinations, but they reported lower anxiety in a computer-based environment. Finally, although typical and retrospective emotions were correlated, only retrospective emotions were associated with examination performance. We discuss the importance of testing environments and time-frames in understanding how to support students’ emotions in testing with particular emphasis on implications for online assessment.
Teaching and learning in clinical rounds: a qualitative meta-analysis

Objective: Literature on the obstacles of clinical rounds is dispersed and has not been well established under a unified systematic investigation. Teaching and learning in clinical rounds, where a variety of skills important for the medical profession, cannot be augmented if barriers related to main factors in the clinical environment are not identified. Methods: A systematic review of English articles using Web of Science, PubMed, Embase, Scopus and Cochrane library were conducted. Relevant keywords and their synonyms were used for the domains “medical students/clinical teachers/barriers and clinical round”. Additional studies were identified by searching reference lists of retrieved articles. All searches for English language articles were conducted within a 10-day period from 25 May to 3 June 2017. No time limit was considered for article searching. We contacted Kerman University of Medical Sciences to locate some studies due to access limitation. In this systematic review, studies on the subject of barriers to clinical rounds from clinical teachers’ and medical students’ perspectives were identified. Our search strategy yielded 600 articles. After title and abstract review, 43 of these were obtained and finally 20 were included in the study. All data were abstracted from the included studies. Two authors independently screened the studies. We used inductive content analysis and categories of barriers were derived from the data. MAXQDA software version 10 was used for data analysis. Results: A total of 20 articles were included and analyzed in depth. Content analysis yielded identification of 320 codes concerning barriers to clinical rounds in six categories classified as system-, climate-, teacher-, student-, patient-, and personnel-related factors. Conclusion: Our investigation depicts primarily main barriers in teaching on rounds. In this regard, effective teaching in clinical rounds is not obtained unless barriers concerning the learning triad and its environment are explored and necessary actions are adopted accordingly

Aim: To investigate the use of Parkia biglobosa leaves as a source of organic nutrients for maize production. Place and Duration of Study: The field experiment was carried out at the research field of the Federal Ministry of Agriculture and Rural Development, Lagos State Field Office, Nigeria during the early planting season (March/April) of 2018. Methodology: A field research was carried out to compare the growth and yield of maize when Parkia biglobosa leaves and inorganic fertilizer were used as nutrients sources. Four factorial treatments combinations of Parkia biglobosa leaves, NPK fertilizer, combined Parkia biglobosa leaves and NPK fertilizer, and a control experiment was ordered in a Randomized Complete Block Design with four replicates. The plants height, number of leaves and surface areas were recorded at 3, 6 and 9 weeks after planting while the maize yields were considered at the end of the experiment. Original Research Article Olatunji et al.; AJRAF, 6(4): 20-28, 2020; Article no.AJRAF. 60993 21 Results: The study showed that the treatment with the combination of Parkia biglobosa leaves and inorganic fertilizer produced the highest indexes of plant tallness, foliage number and surface areas. Maize yields of 2816.66, 2700, 2316.66 and 1566.66 kg/ha were recorded from treatments with Parkia biglobosa leaves and inorganic fertilizer combination, inorganic fertilizer, Parkia biglobosa leaves and the control experiment, respectively. Conclusion: These results reflected that the incorporated effect of Parkia biglobosa leaves and inorganic fertilizer at the rate of 50:50 gives the best maize growth and yield index.
Path analysis studies of EMS-mutagenized mutant population of hexaploid wheat (Triticum aestivum L.)

Mutated genetic resources play a crucial role and are of utmost importance in gene/allele characterization. Currently, hexaploid wheat mutated resources are rarely available. In the present investigation, a mutated population comprising 1,536 EMS-induced mutation lines (M7 generation) of bread wheat (Triticum aestivum L.) were used as an experimental material. Mutant population was developed and maintained at G.B. P.U. A.T, Pantnagar. The experiment was conducted in augmented block design II. in season 2019-20 at Norman E. Borlaug Crop Research Centre G.B. P.U. A.T, Pantnagar. The study revealed that number of tillers per plant recorded significantly higher direct effect on grain yield per plant followed by number of grains per spike, thousand grain weight, plant height, ear length, flag leaf width, grain length, flag leaf area and number of spikelet per spike. The association between grain yield per plant and these characters was significant. The direct negative effects on grain yield was observed by grain width, flag leaf length and peduncle length.
Homeless without benefits: the non-take-up problem

Abstract Despite the extensive literature on non-take-up of rights in welfare states, the problem has been little studied in relation to homelessness specifically. Part of a larger research project on homelessness services, the present study examined the issue in Israel. The review of the literature points to methodological problems in assessing non-take-up, which may be reduced by using administrative data. Based on questionnaire responses of 107 participants working with people experiencing homelessness, 13 interviews, grey literature and quantitative administrative data, the findings suggest that in 2016, only 38% and 48% of people experiencing homelessness in Israel have taken up income and rent support, respectively, due to structural and bureaucratic barriers and cost-benefit calculations that factor in social stigmas. Ways of reducing bureaucratic barriers and ensuring welfare provision to prevent and end homelessness are discussed, as is the possibility of institutional compassion as a way of increasing take-up.
Effects of feeding double strain spores as a probiotics with or without antibiotic growth promoter on broiler performance

The objectives of the study were to investigate the effects of feeding probiotics supplemented diets with or without antibiotic growth promoter on growth performance, carcass characteristics and costeffectiveness of commercial broilers. A gable type open sided house was used for experimental purpose. Three hundred twenty Cobb-500 oneday-old straight run chicks were randomly distributed into four dietary groups having five replications. The number of birds in each replication was 16. Four diets were considered: diet 1: control; diet 2: antibiotic growth promoter (AGP) at a dose of 15g/100kg; diet 3: probiotics (PB) at a dose of 250g/100kg and diet 4: AGP plus PB (15g/100kg+250g/100kg). Birds were vaccinated against common viral diseases as a part of disease prevention program. The records were kept of body weight, feed intake and mortality while weight gain, feed conversion ratio (FCR) and survivability were calculated. Both performance and carcass yield were statistically analyzed for interpretation. Broiler chicks that received PB showed significant improvement in performance (P<0.01) over control with respect to body weight gain, FCR, carcass yield and cost-effectiveness. Feeding AGP alone had comparatively less weight gain, net profit and almost similar feed efficiency compared with PB and AGP+PB groups but its performance was much better than that of control group. The PB fed group showed better meat yield traits. The PB alone group was also more cost effective over control. Feeding PB may be practiced in broiler diet as an alternative to AGP.
Surface Recovery of the CXRS First Mirror of EAST

A radio frequency (RF) capacitively coupled plasma was used to clean the nonplane large size first mirror (FM) used in the charge exchange recombination system (CXRS) of the Experimental Advanced Superconducting Tokamak (EAST). The mirror is made of 316L stainless steel (SS) and has a curved surface with a radius of 1600 mm and dimensions of 300 mm $\times80$ mm $\times40$ mm. Before cleaning, the FM was exposed to the plasma in 12 499 plasma discharges with a total plasma duration time of 86 036 s during three experimental campaigns from 2014 to 2016. An inhomogeneous deposition layer, consisting of carbon (C), oxygen (O), silicon (Si), tungsten (W), and molybdenum (Mo) with deposit particles sizes up to tens of micrometers was detected afterward. To recover the FM surface, argon (Ar) plasma cleaning was performed for 187.3 h in the laboratory. The inhomogeneous deposition was afterward not visible and uniformly removed. Scanning electron microscopy (SEM) and electron energy dispersion spectroscopy (EDS) results indicated that the micromorphology was developed during the cleaning, and few residual particles consisting of C and O also remained and covered about 5.3% of the cleaned mirror surface. The reflectivity of the FM was recovered from 15% to 68% at the wavelength of 532 nm, which was close to the initial preexposure value of 71.4%. A negligible difference of the recovered reflectivity along the FM surface was obtained which demonstrated the cleaning effectiveness and homogeneity of RF plasma cleaning for nonplane large mirrors. To prolong the FM lifetime, RF plasma could, therefore, be considered as one of the possible way for in situ cleaning.
Math anxiety and perfectionistic concerns in multiple-choice assessment

Abstract We examined the relationships between math anxiety, perfectionism and academic achievement in undergraduates enrolled in a course with high mathematical content. Participants were 251 students who completed math anxiety and perfectionism questionnaires, and whose academic achievement was measured via a multiple-choice examination. The number of hits, errors and unanswered questions on this examination were analyzed to explore the possible influence of math anxiety and perfectionism on students’ performance. Results showed that highly math-anxious (HMA) students were more perfectionist than their low math-anxious (LMA) peers, insofar as they were more concerned about making mistakes and had more doubts about their own actions. The HMA group also obtained worse grades than did their LMA counterparts, although this was because they left more questions unanswered, not because they made more mistakes. Analysis of the relationship between math anxiety and the number of unanswered questions revealed that concern over errors and doubts about actions played a mediating role in this relationship. In conclusion, HMA students’ fear of making mistakes and doubts about their own actions are important factors influencing their performance in multiple-choice tests.
Study on Warpage and Reliability of Fan-Out Interposer Technology

The fan-out interposer (FOI) technology with fine pitch is demonstrated and presented for heterogeneous integration as a cost-effective and enabling technology. The co-design modeling methodology is established for the FOI technology, including wafer process-induced warpage, package assembly warpage, and board-level solder joint reliability to optimize the structure design, wafer process, assembly process, and material selection. Through the wafer warpage modeling, desirable glass carrier, photodielectric, and molding compound materials and interposer structure are suggested to reduce the wafer warpage. Effect of stiffener on assembly induced package warpage is simulated and studied. Board-level solder joint reliability is investigated and optimized based on the simulation results. The optimized materials and the structure design are determined based on the co-design modeling and simulation results to achieve the successful FOI wafer fabrication, assembly process, and board-level reliability for extreme large package with FOI.
The financial and operational impacts of European SMEs’ use of trade credit as a substitute for bank credit

ABSTRACT We study the impacts of the use of trade credit on SME financial performance and operational distress in a sample of 74,036 SMEs across 19 EU countries between 2006 and 2015. Under the premise that trade credit acts as a substitute for bank credit, our results show that supplying trade credit improves profitability, but we show little evidence that such an investment is more profitable for bank credit richer SMEs, although such firms did redistribute more bank fund through trade credit to their customers. For receivers, we show that the use of trade credit finance alleviates operational distress, especially for those SMEs facing liquidity constraints, such as those which have less access to bank credit or under credit tightened periods. This distress reduction effect is also reflected in their profitability indicators. However, the longer the average collection period and credit period, the less effective the trade credit effects respectively on improving SME profitability and reducing operational distress.
Physical Fitness Predicts Subsequent Improvement in Academic Achievement: Differential Patterns Depending on Pupils’ Age

We investigated the longitudinal relationship between physical fitness (flexibility, functional strength, and running speed-agility components) and subsequent change in academic achievement across one school year. We also examined whether this longitudinal relationship differed as a function of pupils’ age, controlling for sex, body mass index, and socioeconomic status. Academic achievement in terms of marks in Portuguese and mathematics was recorded from 142 pupils (M = 14.59 years; SD = 1.99, range 11–18), between autumn 2017 and summer 2018. The physical fitness components, including flexibility, functional strength, and running speed-agility, were assessed at the baseline (i.e., at the beginning of the school year). Latent change score modelling revealed that higher physical fitness level at baseline significantly predicted a subsequent improvement in academic achievement across the school year. This longitudinal relationship was significantly stronger in younger compared to older pupils. Physical fitness and its interaction with age predicted 45.7% of the variance in the change in academic achievement. In conclusion, a better physical fitness profile including flexibility, functional strength, and running speed-agility explains a subsequent improvement in academic achievement. This longitudinal relationship seems to be age-dependent.
Effect of finite-rate chemistry and unequal Schmidt numbers on turbulent non-premixed flames modeled with single-step chemistry

The interaction between a quasi-laminar flame and a turbulent flowfield is investigated through direct numerical simulations (DNS) of reacting flow in two- and three-dimensional domains. Effects due to finite-rate chemistry are studied using a single step global reaction A (fuel) + B (oxidizer) yields P (product), and by varying a global Damkoehler number, as a result of which the turbulence-chemistry interaction in the flame is found to generate a wide variety of conditions, ranging from near-equilibrium to near-extinction. Differential diffusion effects are studied by changing the Schmidt number of one reactive species to one-half. It is observed that laminar flamelet response is followed within the turbulent flowfield, except in regions where transient effects seem to dominate.
Study on preparation and performance of fluid loss additive applied to chlorination titanium blast furnace slag

Abstract In cementing operations, slag is gradually used as a mixture of cement materials, which can not only realize the reuse of resources, but also relieve the environmental pressure. In order to explore the fluid loss additive suitable for slag, a new type fluid loss additive AMPS/DMC/AA/DN-1 was prepared by molecular structure design and radical synthesis. The monomers used are 2-acrylamide-2-methyl-propionic acid (AMPS), dimethyl carbonate (DMC), acrylic (AA), unsaturated tertiary amine organic solvent (DN-1). The molecular structure and temperature resistance of the copolymer were characterized by elemental analysis, XPS, infrared spectroscopy, thermal weight loss, and nuclear magnetic resonance hydrogen spectroscopy, and performance evaluation was performed on the titanium-bearing titanium slag doped with AMPS/DMC/AA/DN-1. The results show that when the amount of AMPS/DMC/AA/DN-1 is 2%, the water loss of chlorination titanium blast furnace slag is 24.25 mL, which has good water loss reduction. And the compressive strength of chlorination titanium blast furnace slag is 11.19 MPa, which meets the cementing requirement. In addition, the density of chlorination titanium blast furnace slag is within the range of 1.6–1.9 g/cm3, AMPS/DMC/AA/DN-1 can make the water loss within 50 mL; and it can reduce the water loss in the range of 30 °C–90 °C. Besides, AMPS/DMC/AA/DN-1 can significantly improve the rheological properties and settlement stability of titanium slag. Graphical Abstract

NeuFuzz: Efficient Fuzzing With Deep Neural Network

Coverage-guided graybox fuzzing is one of the most popular and effective techniques for discovering vulnerabilities due to its nature of high speed and scalability. However, the existing techniques generally focus on code coverage but not on vulnerable code. These techniques aim to cover as many paths as possible rather than to explore paths that are more likely to be vulnerable. When selecting the seeds to test, the existing fuzzers usually treat all seed inputs equally, ignoring the fact that paths exercised by different seed inputs are not equally vulnerable. This results in wasting time testing uninteresting paths rather than vulnerable paths, thus reducing the efficiency of vulnerability detection. In this paper, we present a solution, NeuFuzz, using the deep neural network to guide intelligent seed selection during graybox fuzzing to alleviate the aforementioned limitation. In particular, the deep neural network is used to learn the hidden vulnerability pattern from a large number of vulnerable and clean program paths to train a prediction model to classify whether paths are vulnerable. The fuzzer then prioritizes seed inputs that are capable of covering the likely to be vulnerable paths and assigns more mutation energy (i.e., the number of inputs to be generated) to these seeds. We implemented a prototype of NeuFuzz based on an existing fuzzer PTfuzz and evaluated it on two different test suites: LAVA-M and nine real-world applications. The experimental results showed that NeuFuzz can find more vulnerabilities than the existing fuzzers in less time. We have found 28 new security bugs in these applications, 21 of which have been assigned as CVE IDs.
