NUMERICAL SIMULATIONS FOR SHALLOW WATER FLOWS OVER ERODIBLE BEDS BY CENTRAL DG METHODS

In this paper, we investigate the shallow water flows over erodible beds by using a fully coupled mathematical model in two-dimensional space. This model combines the nonlinear shallow water equations, the sediment transport equation and the bed evolution equation. The purpose of this paper is to design a well-balanced and positivity-preserving scheme for this model. In order to achieve the well-balanced property, the coupled system is first reformulated as a new form by introducing an auxiliary variable. The central discontinuous Galerkin method is applied to discretize the model. By choosing the value of the auxiliary variable suitably, the scheme can exactly balance the flux gradients and source terms in the “still-water” case, and thus the wellbalanced property of the proposed scheme can be proved. Moreover, the non-negativity of the volumetric sediment concentration in the sediment transport equation is maintained by choosing a suitable time step and using a positivity-preserving limiter. Numerical tests are presented to illustrate the validity of the proposed scheme.
CORRELATION OF ION CONTENTS WITH ETHYLENE PRODUCTION DURING THE RIPENING PROCESS OF SUGARCANE (SACCHARUM OFFICINARUM L.) WITH THE APPLICATION OF CHEMICAL RIPENERS

Chemical ripeners (Ethephon, Glyphosate and Sulfometuron-methyl) were used as foliar sprays on four sugarcane cultivars (HSF-242, NSG-311, HSF-240, NSG-555) to find their effects on quality, potassium (K) and chloride (Cl) contents and ethylene production. Chemical ripeners significantly increased the sucrose contents, juice purity, recovery % cane and sugar yield based on the mean data of two years. All the sugarcane cultivars sprayed with chemical ripeners responded well regarding early cane maturity and high production of sugar. Variations in antioxidant activities i.e. peroxidase (POD) and catalases (CAT) were also noted indicating the stimulating effects of various chemical ripeners. There was a negative correlation of K and Cl with ethylene production r = -0.8915, -0.7773, respectively. K had a positive correlation with Cl contents (r = 0.92205). Sugar yielding attributes had positive correlations with ethylene while, K and Cl had negative correlations. Upon reaching maturity, ethylene production increased while, K and Cl contents in cane juice decreased resulting in high sucrose contents in sugarcane. It was concluded that chemical ripeners were useful reaching early cane maturity in sugarcane cultivars which were considered mid or late maturing. Chemical ripeners also increased the sucrose contents with high sugar yield by affecting various variables linked to cane maturity. These outcomes can be utilized by researchers and plant breeders to develop early cane maturity varieties during sugarcane variety development programs.
A dictionary of pronouns for Brazilian Portuguese

Function words like articles, prepositions, conjunctions, and especially pronouns are important to Text Analysis as they reveal much more about someone’s psychological state than content words do. In this study, we present the development of a pronoun enriched dictionary for text analysis in Brazilian Portuguese (BP), named PronounBP, which is based on the Brazilian Portuguese language version of the LIWC dictionary. Pronouns have great importance in Text Analysis, so we included in PronounBP as many Portuguese pronouns as possible. In this work, we carry out two experiments. The first one presents a statistical comparison of percentage values in categories obtained for bilingual texts, using the English LIWC dictionary, PronounBP and the already available BP LIWC dictionary. It provides satisfactory results since higher correlation results were obtained using PronounBP. We also produced an empirical evaluation in a computational linguistic analysis task, and PronounBP has also achieved better results than the BP LIWC dictionary.
Document Clustering with Concept Based Vector Suffix Tree Document Model

– This work aims to extend a document representation model which is elegant by combining the versatility of the vector space model, the increased relevance of the suffix tree document model, which takes word ordering into account and retaining the relationship between words like synonyms. The effectiveness and the relevance of this document model can be evaluated by a partitioning clustering technique K-Means and then a systematic comparative study of the impact of similarity measures in conjunction with different types of vector space representation on cluster quality may be performed. This document model will be called the concept based vector suffix tree document model.
Gender differences in plant use knowledge within a traditional fishing community in northeastern Brazil

Background: Understanding patterns in traditional plant use knowledge is crucial for assisting policy making with regard to nature conservation, human nutrition, human health, as well as educational and participatory processes in traditional communities. We aim to document and describe local ethnobotanical knowledge and test the hypothesis that gender structures the knowledge of plant use possessed by artisanal fishers in a fishing community in northeast Bahia, Brazil. Methods: Through semi-structured interviews and guided walks with traditional experts, we recorded the local knowledge of plant use with regard to medicine, food, wood and fibre, and ritualistic/religious practices. The data were analyzed using quantitative indices of use value (UV) and informant consensus factor (ICF), and gender differences in plant use knowledge was analyzed using a non-metric multidimensional scaling (NMDS ordination). Results: A total of 161 ethnospecies with local names were registered, including 122 species of plants from 52 botanical families based on scientific (academic) taxonomy, which were identified along with the plant parts used, habitats, and preparation methods. Female and male traditional experts possess a different set of plant use knowledge, with women generally citing more food and medicinal plants, and men citing more wood and fiber plants. Conclusions: Gender differences in plant use knowledge can be explained by the different occupations of the male and female traditional experts. The results of this study provide a framework for extending our ethnobotanical investigations to other traditional fishing communities, and also to examine other social and demographic factors influencing traditional knowledge related to plant use.

Exploring Visitors Subjectivities toward Authenticity of the Suzhou UNESCO Heritage Site Using Q-Method

This article was designed to investigate the perceived authenticity of World Heritage Site located in Suzhou, China. With a history of over 2000 years, the Classical Gardens of Suzhou was recognized as World Cultural Heritage by UNESCO for its elegant embodiment of Chinese traditional culture. A brief overview of the development of World Heritage Site and authenticity leads us into the discussion of examining the gap between the objective authenticity defined by UNESCO and the perceived authenticity identified by visitors. Through applying Q method, we analyzed and interpreted heritage tourists’ subjectivities on the perceived authenticity, integrity, protection and tourism management at Suzhou UNESCO heritage site. The findings indicated the perceived authenticity can be divided into four different clusters. By defining the clusters, some implications can be suggested to better manage Suzhou UNESCO heritage site and refine the development of heritage tourism to make Suzhou a global world heritage city.
Securing the Internet of Things from the Bottom Up Using an Immutable Blockchain-Based Secure Forensic Trail

—It has traditionally been the case that the Internet of Things represents the weak link in the corporate information system chain. While research has tried to improve the status quo, this has brought a new challenge to the table. Corporate systems, while generally much stronger than Internet of Things systems, are not, in themselves, totally secure. This is especially true of cloud-based systems. This major ﬂaw arises because of the difﬁculty in safeguarding the forensic trail of corporate systems. The ﬁrst thing the attacker does as soon as they have penetrated a corporate system, is to delete all the evidence of their entry from the forensic records of the corporate system, and there is usually very little to prevent this from happening. This is why it is such a challenge for authorities to trace attackers and bring them to account. The forensic trail is often the least protected part of corporate systems, but is arguably the most important from a compliance point of view. We show how it is possible to secure the forensic trail for corporate systems users who adopt these secure IoT approaches, by adopting the straightforward approach we suggest here to protect the forensic trail through the use of Blockchain. This will allow corporates to ensure the overall system can be secured, but more importantly, will provide a means to ﬁght back against the attackers.

In addition, the hybrid method on the principle of double organization solves such problems of existing recommendation methods as excessive similarity of recommendations, potentially small number or no proposals at all by compensating data from one block of data from another.
Pulsed Plasma Polymerization of Perfluorooctyl Ethylene for Transparent Hydrophobic Thin Coatings

Herein we report on the deposition of transparent hydrophobic thin coatings by radio frequency plasma polymerization (PP) of perfluorooctyl ethylene (PFOE) in both pulsed and continuous wave (CW) modes. The chemical compositions of the resulting PP-PFOE coatings were confirmed by means of Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The thicknesses and surface morphologies of the coatings were examined using surface plasmon resonance spectroscopy and atomic force microscopy. The surface wetting properties and optical transmittance were measured using a water contact angle goniometer and UV-vis spectroscopy. The FT-IR and XPS data showed that the PP-PFOE coatings deposited in the pulsed mode had a higher retention of CF2 groups compared to those from the CW mode. While the water contact angle of the freshly deposited PP-PFOE from the pulsed mode showed a decrease from 120 degrees to 111 degrees in the first two days, it then remained almost unchanged up to 45 days. The UV-vis data indicated that a PP-PFOE coating 30.6 nm thick had a light transmittance above 90% in the UV and visible ranges. The deposition rates under various plasma conditions are also discussed.
INTERVARIABLE INFLUENCE ANALYSIS OF HIERARCHY OF EFFECT (HOE) MODEL IN CROSS-BORDER E-COMMERCE (STUDY CASE: SHOPEE AND LAZADA)

Manuscript type: Empirical research Research aims: This study was conducted to analyze and develop the intervariable influence within the stages of HOE Model in CBEC context. Design/methodology/approach: Based on the Hierarchy of Effect (HOE) model which consists of the stages of customer progression of learning and decision-making as a response of their shopping experiences. A total research data of 1,651 respondents were collected through a structured questionnaire. SEM method was used to test the proposed research model. Research findings: HOE Model was found to vary based on the level of product cognition and platform involvement. Two case studies provide different results which occur due to the different shopping journey held by the customer from the stages of cognition and involvement to the decision of making a purchase. Theoretical Contribution/Originality: The less attention that was given to the customer behavior in CBEC context has driven the authors to analyze customer journey from product cognition to actual behavior stage in CBEC context. The modification towards previous research model is conducted to extend the analysis with a purpose to provide a full picture of the customer experience and the factors that influence their buying decision. Practitioner/Policy Implication: Provide insights to encourage parties involved for implementing strategic plans that could escalate market presence and competitiveness of Indonesia CBEC at the global trade. Research limitation/Implications: The authors extend the research model to actual behavior stage which creates a wider unexplored variables on the formation of perceived trust and the overall affective stage.
First-principles study on Al4Sr as the heterogeneous nucleus of Mg2Si

The interfacial structure, electronic structure, work of adhesion and interfacial energy of the Al4Sr(100)/Mg2Si(100) interface have been studied with first-principles calculations to clarify the heterogeneous nucleation potential of the Al4Sr particle for a primary Mg2Si phase. Eight models of the Al4Sr(100)/Mg2Si(100) interface with OT and HCP stacking were adopted for the interfacial model geometries. The results show that the Al-Mg terminations of HCP and Al-Si terminations of OT stacking, with lower interfacial spacing and higher interfacial adhesion, are the most favorable structures after relaxation. Al-Mg- and Al-Si-terminated interfaces, with a lower interfacial distance, form chemical bonds more easily. Metallic bonds are formed near the Al-Mg-terminated interface, while the Al-Si-terminated interface exhibits predominantly covalent bond characteristics. Moreover, the calculated interfacial energies of both terminations are negative in conditions involving excess Mg atoms. The interfacial energies of Al-Si are lower than those of Al-Mg termination, indicating that the Al-Si-terminated interface is more stable. From thermodynamic analysis, we discover that the Al4Sr particle can be an effective heterogeneous nucleation substrate for Mg2Si in a Mg-Al-Si alloy melt.
Detection of phosphate solubilizing bacteria from rhizospheric soil of agricultural crops in Erode district

Phosphorus is a second key plant nutrient and the ‘kingpin’ in Indian agriculture, occupies an exclusive position both in conventional as well as in alternative agriculture. However, the phosphate solubilizing bacteria (PSB) converts the insoluble phosphate into biologically available form through the production of organic acids. Hence, the present study explored the presence of PSB from the Karavalasu agricultural field, Sivagiri, Erode District. The percentages of bacterial solubilization were 14.40 % to 60.70 % in non rhizospheric and rhizospheric crops adhering to root soils respectively.Out of 14 morphologically distinct isolates of PSB, two isolates (PSB8 and PSB11) displayed high P solubilization efficiency on solid medium amended with tricalcium phosphate Ca3(PO4)2 as the insoluble source (0.2 %). They were further characterized and continued with identification used by Picovskaya’s selective medium. The selective medium was incubated for 48 hours at a temperature of 37C. The characterization was done for two strains by looking at the colony morphology and biochemical properties. The isolates showed the optimum pH for growth of the organism was pH 7 and the optimum temperature was 37 C. Two strains exhibited significant release of P at the concentrations of 1.96 and 2.26 mg/l by PSB – 8 and PSB – 11 respectively on 10 day of incubation in broth medium amended with Ca3(PO4)2. The strains released acids as evident by decline in pH of the broth medium. They also secreted IAA with the maximum of 17.06 mg/l by PSB 8 with Ca3(PO4)2 as a source of P. The potential strains for P solubilization were identified using 16S rRNA as Bacillus megaterium and Pseudomonas aeruginosa for further application as bioinoculants to agricultural fields. Finally we afford some indication that the use of Phosphate solubilising microorganisms will support sustainable agriculture and conclude that this knowledge is ready for commercial utilization in various regions worldwide.
MLPA method for PMP22 gene analysis

DNA copy number alterations are responsible for several categories of human diseases and syndromes. These changes can be detected by cytogenetic studies when there is involvement of several kilobases or megabases of DNA. Examination of sub-microscopic changes is possible by using short probes flanked by the same primer pairs. Multiplex ligation-dependent probe amplification (MLPA) is a simple, high resolution method by which not sample nucleic acids but probes added to the samples are amplified and quantified. Charcot- Marie-Tooth disease type 1A (CMT1A) is the most common inherited peripheral neuropathy with a prevalence of about 1/10000. By a gene dosage mechanism, commonly trisomic overexpression of PMP22 results in CMT1A whereas its monosomic underexpression causes hereditary neuropathy with liability to pressure palsies (HNPP). We applied MLPA to the PMP22 gene in order to develop an efficient and sensitive test for detecting these gene dosage changes. The method was used on 56 samples collected for a previous comparative study on routine methods for CMT1A diagnosis used in our laboratory. All diagnoses agreed with results from other methods. The MLPA PMP22 assay is a simple, fast and accurate screening test for molecular diagnosis of CMT1A and HNPP.
Benefits of Morinda citrifolia L. Fruit Extract on Methotrexate Induced Mitochondrial Toxicity – An In Vivo Study in Rat Liver Mitochondria.

Mitochondrial dysfunction has been implicated in the etiology of many drug-induced toxicities. Methotrexate (MTX), an antimetabolite and one of the folic acid antagonists, has widely been used to treat a variety of disorders such as cancer and several autoimmune disorders. It induces oxidative stress which results in many of its ill effects on different target and non-target organs, altering different metabolic pathways and interfering mitochondrial bioenergetics. Here, in our study, we have assessed the toxicity of methotrexate on rat liver mitochondria and its modulation by Morinda citrifolia L. (Noni) fruit extract. MTX significantly affects mitochondrial function, and activity of important mitochondrial enzymes such as Succinate dehydrogenase (SDH), Malate dehydrogenase (MDH) and NADH dehydrogenase. Reduced Cytochrome C – oxidase activity and Reduced glutathione (GSH) levels in MTX treated group (p<0.001) was also observed. An increase in the activity of calcium dependent ATPase (Ca dependent ATPase) was observed along with increase in lipid peroxidation (lpx), and significant decrease in mitochondrial protein in MTX treated groups. Liver mitochondria of animals administered with Noni extract did not show any toxicity and combination of aqueous Noni fruit extract and methotrexate showed amelioration of toxicity as compared to methotrexate alone. Our study suggests that Noni can have significant protective effect on liver injury induced by MTX. Nutraceutical supplement like antioxidants found in edible plants such as Noni may be a safe and effective way of alleviating the liver toxicity. Hence, we propose that combination of Noni and methotrexate can be potentially safer combination in cancer therapy.
APPLICATION OF METHYLIGHT APPROACH FOR DETECTION OF CYTOSINE METHYLATION IN FLAX SEEDS GROWN NEAR CHERNOBYL

Nowadays, various approaches for the precise DNA methylation analysis are known. This study applied an advanced MethyLight approach for precise detection of cytosine methylation. Chernobyl area is still contaminated by long-lived radioisotopes thus the potential risk of DNA damage by radiation remains relatively high. Plants as sessile organisms are directly affected by irradiation. For the analysis presented herein, flax seeds grown on the experimental fields near Chernobyl have been used. Cytosine methylation was quantified in the specific coding region of Fatty acid desaturase 3A gene which has an important function in fatty acid biosynthesis. Quantitative real-time MethyLight revealed fully methylated sequence in the targeted gene.
