Evaluation of Block-Based and Text-Based Coding

Beginner programmers usually have difficulties in creating syntactically correct programs. Some cases it is facilitated by features that help to enter text code, and in other cases by block-based programming that replaces conventional text-based coding. In my article, by comparing and evaluating the two possible types of coding, I prove that it is easier for beginners to learn block-based programming, but advanced programming requires transition to text-based coding. This will also be confirmed by three interviews with IT teachers. Then, I will point out that transition is possible within the same programming area and I will refer to my interviewees' experiences with the transition.
EXTRACTION OF ACTINIDES(III), (IV), (V), (VI), AND LANTHANIDES(III) BY STRUCTURALLY TAILORED DIAMIDES

Eleven diamide extractants having the different backbones were synthesized and their extractability for lanthanides(III) and actinides(III), (IV), (V) and (VI) were measured and compared. The diamides investigated include (CH2) n ─(CONR1,R2)2, (n = 0, 1, 2, 3), O─((CH2) n′─CONR1,R2)2, S─((CH2) n″─CONR1,R2)2, and SS─((CH2)n′″─CONR1,R2)2, (n′, n″, n′″ = 1, 2). The diglycolamide introducing an ether oxygen into the main frame, O─(CH2─CONR1,R2)2, exhibited the highest extractability for An(III), (IV) and (VI), as compared with the other bidentate diamides. It is clear from the present results that the thiadiglycolamide, TDGA, which substitutes ether sulfur atom for oxygen in DGA molecule, also enhances the extraction of actinides. The lanthanide pattern, the distribution ratios versus the atomic number, by diglycolamide in HNO3-n-dodecane system exhibited a gradual increase of distribution ratio with increase in the atomic number, the opposite trend to that obtained by the other diamides.
Investigating the effect of topical marcain 0.25% and lidocaine 2% on pain relief following herniorrafia

Introduction: Pain is one of the major postoperative problems, and lack of proper pain management can lead to complications such as increased hospital stay, increased recovery time and more medical costs. There are several methods used to control postoperative pain, the most common of which are administration of analgesics and local anaesthetics at the site of surgery. Therefore, considering the reported side effects, this study tends to investigate the effect of two local anesthetic methods in patients undergoing herniorrafia. Materials & Methods: This study was performed as a clinical trial on 60 patients undergoing herniorrafia in Shariati Hospital of Tehran in 2018. All patients underwent general anesthesia and Liechtenstein. Patients were randomly divided into three groups: marcain, lidocaine, and control. Then, severity of pain was assessed based on VAS after one hour, in the afternoon on the operation day and the day after the operation. Frequency of prescribing pethidine was recorded based on VAS. Statistical analysis of the collected data was performed by one way ANOVA. Results: Three groups were not significantly different in terms of age. Pairwise comparison of groups revealed that severity of pain at the end of surgery and in the afternoon of the operation day was significantly different between marcain group and lidocaine group as well as postoperative marcain group and the control group (P=0.001); however, pain severity was not significantly different between lidocaine and control groups. Conclusion: marcain administration at the surgical incision site compared to lidocaine reduces pain severity and reduces the average administration of pethidine in patients.
Recent advances in innovative strategies for enhanced cancer photodynamic therapy

Photodynamic therapy (PDT), a non-invasive therapeutic modality, has received increasing attention owing to its high selectivity and limited side effects. Although significant clinical research progress has been made in PDT, the breadth and depth of its clinical application have not been fully realized due to the limitations such as inadequate light penetration depth, non-targeting photosensitizers (PSs), and tumor hypoxia. Consequently, numerous investigations put their emphasis on innovative strategies to overcome the aforementioned limitations and enhance the therapeutic effect of PDT. Herein, up-to-date advances in these innovative methods for PDT are summarized by introducing the design of PS systems, their working mechanisms and application examples. In addition, current challenges of these innovative strategies for clinical application, and future perspectives on further improvement of PDT are also discussed.
Drivers of E-Commerce Adoption amongst Small & Medium Sized Enterprises (SMEs) in the Business Service Sector

- Technology has played a significant role in the development of business to business (B2B) or business to consumers' (B2C) electronic commerce (or e-commerce) over the recent decades. The purpose of this study is to empirically examine determinants of e-commerce adoption among small-and medium sized enterprises (SMEs) in the business services sector in a progressively developing nation. This study tested six hypotheses focusing on organizational, technological and environmental factors that may affect e-commerce adoption. Using judgemental sampling approach, a total of 110 feedback were gathered via online questionnaire based survey. The study employed SmartPLS 3.0 (Partial Least Square) structural equation modelling statistical software to confirm the hypotheses of this study. Structural model analysis was conducted and it was revealed that perceived relative advantage, perceived compatibility, e-commerce knowledge and expertise, external change agent and competitors' pressure have positive and significant influence on the SMEs respondents' e-commerce adoption. The study found that the most significant factors influencing e-commerce adoption among SMEs in Selangor was perceived relative advantage, to which managers or small and medium-sized enterprises see the potential advantage of e-commerce . The implication of this study is that SMEs need more exposure on the benefit of technolgy and intervention to guide them to change from traditional business to online business.
Activated Carbon Production from Date Stones Using Phosphoric Acid

Abstract The effects of activation time and activation temperature on the yield and the adsorptive capacity towards iodine were studied. The yield and the quality of the activated carbon prepared by using H3PO4 were compared with that prepared from date stones using the same equipment, and under similar conditions by using ZnCl2 as an oxidizing agent. The iodine number for the produced activated carbon was higher when H3PO4 was used, compared to that when ZnCl2 was used. The yield obtained when H3PO4 was used was lower than the yield when ZnCl2 was used. The iodine number increases significantly with increasing the activation temperature.

Forecasting Short Term Return Distribution of S&P BSE Stock Index Using Geometric Brownian Motion: An Evidence from Bombay Stock Exchange

For accurate forecasting of stock price, we should have to understand the process and according to that, we can develop the model to decide the best possible values of forecast. Geometric Brownian Motion model is a mathematical model used for forecasting the future stock price and highly accurate as compared to other model and also gives high returns. It helps the investors to take further decisions on their investment. Before forecasting the stock price using Geometric Brownian Motion model, Kolmogorov-Smirnov test and Q – Q plot technique were conducted on the sample data to conclude that the data are normally distributed and feasible to forecast. The algorithm starts from calculating the stock returns, drift and volatility to predict the return distribution at specific time‘t’. Simulations are performed using log volatility equation with the closest behavior to the S&P BSE closed stock price. The closest forecast simulation with actual stock closed price is selected with the more precise value of drift and volatility to proceed in Geometric Brownian Motion model. In order to determine the forecast accuracy as well as performance of the model Mean Absolute Percentage Error (MAPE) is calculated. Since MAPE < 10% i.e. 5.41 %, it implies that Geometric Brownian Motion model is highly accurate and an appropriate model for forecasting stock price.
Effect of total nitrogen content and NH4/NO3 ratio on biomass accumulation and secondary metabolite production in cell suspension culture of Salvia nemorosa

Woodland sage (Salvia nemorosa) is an important native medicinal plant in Iran and is considered as a rich source of phenolic and flavonoids compounds. The present research was conducted with respect to the optimization of medium for biomass accumulation and secondary metabolite production in cell suspension culture of S. nemorosa. In this research the effects of total nitrogen content (0, 15, 30, 60, 90, and 120 mM) and NH4 /NO3 ratio (0:60, 10:50, 20:40, 30:30, 40:20, 50:10, and 60:0) were studied in the Murashige and Skoog Medium on biomass growth, total phenolic, flavonoid and rosmarinic acid contents. The maximum accumulation of fresh biomass (294.80 g/l) and total phenolic content (76.61 mg GAE/g DW) was obtained in the medium supplemented with 90 mM nitrogen. The highest rosmarinic acid content (16.41 and 16.16 mg/g DW) was recorded in the medium containing 30 and 60 mM nitrogen. Increasing total nitrogen above 30 mM resulted in a decline in rosmarinic acid production. The ammonium to nitrate ratio also affected the biomass growth and secondary products accumulation. The highest fresh biomass accumulation (296.52 g/l), total phenolic content (87.30 mg GAE/g DW) and Rosmarinic acid content (18.43 mg/ DW) were recorded in 10:50 ratio of NH4 /NO3 -. Increasing the NH4+ level or complete elimination of it from culture medium reduced the rosmarinic acid and total phenolic content of S. nemorosa. Our findings revealed that Woodland sage cell suspension needs both nitrogen forms, but ammonium is required at low concentration and nitrate at high levels. The results of the current study are beneficial for medium optimization for the establishment of large scale and bioreactor assisted cell culture of woodland sage for the production of phenolic acids.
ON THE PERFORMANCE OF THE STOCHASTIC FISTA

In the ﬁeld of convex optimization, one is frequently lead to solve a composite minimization problem involving a smooth function F and a non smooth function G . In this context, it is well known that the classical proximal gradient algorithm can be accelerated using the Nesterov technique, which leads to the celebrated FISTA. This paper investigates a stochastic version of FISTA that can be applied to the case where the function F is intractable, but can be represented as an expectation. Although it is rather well known that in the stochastic case, the Nesterov acceleration does not bring a clear advantage on the long term over the averaged proximal gradient algorithm, it is demonstrated in this paper that it is beneﬁcial during the ﬁrst iterations. This argues in favor of the Nesterov acceleration in many situations in machine learning, where only a few algorithm iterations are required. The technique is based on the study of a Lyapounov function which is inspired by the ODE method applied to the Nesterov acceleration.
Investigating the Semantic Wave in Tutorial Dialogues: An Annotation Scheme and Corpus Study on Analogy Components

We introduce an annotation scheme and corpus study to investigate the use of base and target components of analogies in tutorial di-alogues. We present the development of the scheme and test its ﬁnal form on a corpus of one-to-one tutorial dialogues on computer science, for which we achieve over 0.77 multi-rater inter-annotator agreement. We then annotate data from the same corpus to investigate the use of semantic wave structures from Legit-imation Code Theory in tutoring, and we ﬁnd a regular adherence to semantic wave structures in explanations which use analogies. We further identiﬁed different semantic wave shapes and show their distributions. We conclude that semantic waves and the novel characterisation of analogical explanations in tutorial dialogues reported in this investigation can be useful tools for both the analysis of human tutorial dialogue and future implementation of tutorial dialogue systems.
Pollard Rho on the PlayStation 3

This paper describes a high-performance PlayStation 3 (PS3) implementation of the Pollard rho discrete logarithm algorithm on elliptic curves over prime ﬁelds. A record has been set using this implementation by solving an elliptic curve discrete logarithm problem (ECDLP) with domain parameters from a currently standardized elliptic curve over a 112-bit prime ﬁeld. Solving this 112-bit ECDLP instance required 62 . 6 PS3 years. Arithmetic algorithms have been designed for the PS3 to exploit the SIMD architecture and the rich instruction set of its computational units. Though our implementation is targeted at a speciﬁc 112-bit modulus, most of our implementation strategies apply to other large moduli as well.
A Case for Timing Error Resilience-Aware Compilation

—Traditionally, processors have been designed to operate correctly under worst case operating conditions. However, the growing impact of process and dynamic variations on shrinking device technologies has increased the cost of ensuring correctness through traditional guardbanding methods to prohibitive levels. To deal with rising variability more efﬁciently, error resilient timing speculative design techniques have been introduced. These techniques allow conservative design constraints to be relaxed, increasing efﬁciency at the expense of occasional errors, which are corrected or tolerated by an error resilience mechanism. Although timing speculation and error resilience techniques for processors have grown in popularity, the programs that run on timing speculative processors are still compiled for a traditional target – a processor that produces no errors. Since the program binary determines the utilization pattern of the processor, which in turn inﬂuences the error rate of the processor and the efﬁciency of timing speculation, we propose that binaries for timing speculative processors should be compiled to exploit the error resilience of the processor for maximum efﬁciency beneﬁts. In this paper, we make a case for compiling for timing speculation to increase the efﬁciency of error resilient processors.
Rhetorical Effects of Puns in English and American Literature and Their Translation

With the continuous development of China’s science and technology and economic globalization, literary works can not be ignored as bridges between people in various countries and regions. However, in British and American literary works, most famous writers like to use pun rhetoric methods in their literary works, making it more difficult for readers to understand the meaning of the works. The purpose of this article is to study the rhetorical effects of puns in English and American literature and their translation. This article analyzes the meaning and form of puns, and studies the rhetorical effects and translation methods of puns in depth. The translation strategies include equivalent literal translation and free translation. This article uses a combination of literature research, theoretical analysis, and statistical analysis. The experimental object is four literary works. Ten chapters of each work are randomly selected to count the number of puns using translation strategies in these ten chapters. Statistics show that more translation strategies are used for equivalent literal translation. The experimental statistics of this paper show that the number of equivalent translations is 116 and the number of free translations is 32.

The predator-prey model on squids and anchovies fisheries in Jepara District, Central Java, Indonesia

Abstract. Wijayanto D, Bambang AN, Kurohman F. 2020. The predator-prey model on squids and anchovies fisheries in Jepara District, Central Java, Indonesia. Biodiversitas 21: 5698-5703. Traditional fisheries dominate marine fisheries in Jepara District, Central Java, Indonesia, including the lift net. The catch of the lift net includes squids and anchovies. The ecological relationship between squids and anchovies must be investigated to develop squids and anchovies management. Without proper modeling, the management of anchovies and squids can lead to over-exploitation of both types of commodities. This study aimed to develop the predator-prey model of squids and anchovies fish in the Jepara District. We conducted predator-prey modeling in squids and anchovies using production and fishing effort data from 2010 to 2019. This research showed a predator-prey relationship between squids (as a predator) and anchovies (as prey) in Jepara District. The anchovy’s production function follows the equation: CA = 14,507 E-51 E2 + 0.41 CS or CA = 4,444 E-15.49 E2. The production function of squids follows the equation: CS = 35,156 E-124 E2-2.42 CA or CS = 24,385 E-86 E2. The optimal fishing effort for anchovies and squids production is 144 units of lift net and 141 units of lift net.
