The existing VUMP within the last decade has been brought into account in consideration both data collection and discussion processes. This study mainly focuses on identifying the characteristics and the implementation directions of the VUMP. In order to clarify these research questions, the implementation data from the Ministry of Public Works and Transport (MPWT), project investments data from the Ministry of Planning and Investment (MPI), and in-depth interview technique in the related sectors are utilized. From these data, the comparison analysis is applied crucially to learn the crossed dimensions between the existing VUMP and the implementation effectiveness.&nbsp;&nbsp; Regarding the results, the implementation processes and administrative sectors are the paralleled issues in driving of VUMP. Therefore, this study suggests the possible solutions with combination of top-down and bottom-up approaches in the implementations. The top-down approach deals with strategic development direction, defined by the master plans. It is suggested that in the framework of implementing the master plans, economic, environmental, financial, and norm of social instruments should be applied in combination with regulative devices, as the later solely could be ineffective. On the other hand, the bottom-up approach emphasized on community empowerment and inclusion of people at the grass-root level into development processes. In order to move forward the collective actions in implementation of the VUMP, it is crucial to encourage the common understanding, share directions, and collaborations with various sectors.</p> 2020-06-17T08:47:02+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/5966 Consistency, Stability and Convergence of the Viscous Garabedian and Korn (VGK) Method 2020-06-17T08:52:42+00:00 Dr. Salah.J.S. El-Ibrahim salah13@gmail.com <p>The Viscous Garabedian and Korn (VGK) is a computational fluid dynamics (CFD) code, used for the prediction of viscous flows around two dimensional aerofoil sections (mapped onto a circular grid) in a subsonic free stream. The code is written in “Fortran 77” and solves the full potential flow equations using a finite difference algorithm. The code has been recently published commercially with a data preparation routine to facilitate its use [1]. The present work investigates the code’s consistency, stability and convergence in the hope that it will shed light on the code’s performance and limitations under various flow conditions and code’s numerical parameters.</p> 2020-06-17T08:52:42+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/5947 Fibre Characteristics of Delonix regia (Hook.) Raf. Wood as Indices of its Suitability for Papermaking 2020-06-17T09:02:43+00:00 Josiah TB Riki rikijosiah@gmail.com Oluwadare Abiodun Oluwafemi aoluwada@gmail.com <p>The fibre characteristics of Delonix regia, a fast and deciduous tropical tree with form like leaves that is considered one of the most beautiful trees in the world was evaluated to assess its potential for pulp and paper making. Three trees of <em>D. regia</em> were used for the study, they were obtained at different locations within University of Ibadan main campus, Ibadan, Oyo State, Nigeria. Samples were collected at base (10%), middle (50%) and top (90%) portion of the merchantable height. At each sampling height, strips of 2.5cm were removed from the centre of the discs and divided into 3 zones namely: corewood, middlewood and outerwood based on the relative distance from the pith. Slivers were obtained from each of the zones and macerated in equal volume of glacial aceticacid and 30% hydrogen peroxide at 80oC in an oven. Data were subjected to statistical analysis of 3×3×3 factorial experiment in a completely randomized design (CRD) and Mean±SEM. However, a follow-up test was carried out using the least significant difference test (LSD) at 5% level of probability. A total of twenty whole fibres were measured in swollen conditions with a calibrated eye piece microscope from each sampling zone for fibre characteristics evaluation viz: fibre length (FL), fibre diameter (FD), lumen width (LW), cell wall thickness (WT), runkel ratio (RR), Coefficient of rigidity (CR), Slenderness ratio (SR), Flexibility ratio (FR), F-factor (FF) and solid factor (SF). &nbsp;The results obtained show that <em>Delonix regia</em> has the following mean value: FL (1.34mm), FD (39.42µM), LW (26.83µM), WT (6.49µM), RR (0.55%), CR (16.95%), SR (36.03%), FR (68.45%), FF (236.33) and SL (1390408.51). Based on the derived value such as the Runkel ratio of 0.55 which is less than 1 compared favourably with other known species for pulp and paper making. The values indicate the suitability of the specie for pulp and paper production in a place where there is shortage of wood material for this purpose.</p> 2020-06-17T09:02:43+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/5878 Corn Seedlings Have Tolerance to Water Deficit 2020-06-18T06:44:00+00:00 Sabrina Reis de Miranda sabrinareis122@gmail.com Luiz Felipe Soares AGuiar lfs_aguiar@mail.uft.edu.br Susana Cristine Siebeneichler susana@uft.edu.br Ládila Lima Luz ladilalluz@gmail.com Bianca Reis de Miranda biancareisdemiranda@hotmail.com Rodrigo de Castro Tavares rocatavares@uft.edu.br Maria Aparecida Alves Sugai sugai@uft.edu.br Álida Filomena Andrade alidafa@uft.edu.br Thadeu Teixeira Júnior thadeupesquisa@gmail.com <p>The present work aimed to evaluate the germination and seedling growth of two corn cultivars under water deficit conditions induced with manitol solutions, associated with doses of humic substances. The experiment was carried out at the Seed Laboratory of the Federal University of Tocantins - UFT, in Gurupi, Tocantins. Seeds of two cultivars were used: M274 and UFT Cerrado; and the product based on humic substances: Humix. For each cultivar, the factorial experiment (5×3) was mounted in a completely randomized design, and the treatments were composed of five osmotic potentials, with three doses of Humix. Germination percentage, primary root and epicotyl length, seedling dry mass and absolute growth rate were evaluated. The results were submitted to the F test by analysis of variance with probability of 5%, and when the effect of the doses was significant, the data were submitted to regression analysis. It is concluded that the biostimulant Humix had no expressive effect on germination and that the reduction of osmotic potential does not affect germination itself, but affects seedling growth, as osmotic potential becomes more negative.</p> 2020-06-18T06:44:00+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/5329 Integration Between Lean Manufacturing and Other Quality Tools: A Scale Development 2020-06-18T06:55:40+00:00 Fabio Eberhardt Teixeiraa feteixei@ucs.br Ademar Galelli agalelli@ucs.br Cintia Paese Giacomello cpaese1@ucs.br <p>In order to improve organization’s performance, both in quality and productivity, several quality programs were created and implemented, with recent highlight to Lean Manufacturing (LM). All these initiatives are based on the involvement of employees, managers and organizational procedures, and it is expected that there will be some interaction between them. This paper describes the development and validation of a multi-item scale, an instrument which measures how employees perceive the integration between a production system based on the principles of Lean Manufacturing with other quality tools already used in the companies. The method included analyzes related to apparent validity, content validity, total item correlations, factor analysis and reliability. A questionnaire submitted to 317 respondents from a population of 1,699 employees of a metal-mechanic company included a proposed scale of 10 items to evaluate the integration between LM and other quality tools. After the analysis of the data, two questions were excluded because they did not present relevant factor loadings and the other eight questions resulted in two factors (Structure of integration of SP with other tools and Results in integration between SP and other tools). Confirmatory factor analysis confirmed that these factors constituted a model with good fit.</p> 2020-06-18T06:55:40+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/5982 Anti-hemorrhagic Activity of Wild Custard Apple (Annona senegalensis) Ethanolic Leaf Extract on Spitting Cobra (Naja negricollis) Metalloprotease. 2020-06-26T22:32:15+00:00 David Christopher Bando bandomidase@gmail.com Emmanuel Odiba Ogu talk2odibs@mail.com Imbasire Nuhu imbasi4real@gmail.com Achinawa Daniel Suleiman achinawa@gmail.com Hannah Nuhu Tubasen hannahnuhu247@gmail.com Kefas Funu kefasfunu@gmail.com Polly Shingu Jesse polly_jesse@yahoo.ca Rebecca Ayodele Segun rebeccatayodele@gmail.com <p>The main feature of <em>Naja nigricollis</em> venom is its high proteolytic activity responsible for most of local and systemic effects observed during envenomation by this snake.

The use of antioxidants from natural ingredients is an effort to overcome premature aging and counteract the harmful effects caused by free radicals. Black soybean (Glycine soja), which easily obtained in Indonesia, contains a nutritional value that is very good for human health. The protein content is quite high (40.4 g / 100g) and rich in antioxidants. The results presented in this study revealed that black soybean extract (Glycine max (L.) Merr.) Had a higher antioxidant activity of FRAP compared to Daidzein compounds, black soybean extract had antiaging activity through better collagenase inhibition compared to Daidzein compounds. The largest FRAP activity at 50 μg / mL black soybean extract concentration was 146.35 μM Fe (II) / μg) and Daidzein 50 μg / mL concentration was 96.93 (μM Fe (II) / μg). Anticolagenase activity based on the IC50 value of black soybean extract was 84.73 μg / mL, and Daidzein was 98.18 μg / mL. From the above results, it can conclude that ethanol extract of black soybeans has excellent potential as an antioxidant that is useful as inhibiting collagenase.</p> 2020-06-26T22:41:08+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/5715 Ferric Reducing Antioxidant Power (FRAP) and Inhibition of Collagenase Enzyme Activity from Ethanol Extract of Pineapple (Ananas cosmus (L.)

The objective and main contribution of this paper are to assure the anonymity in VANET environments. In the proposed blockchain method, before packaging transactions into blocks, anonymity risk reduced through techniques such as k-anonymity, graph processing, dummy node, and silence period. This paper addresses the challenges of anonymous servers, such as update challenges and single point of failure, by exploiting append-only, distributed, and anonymity features. Although mounting the blockchain process with asymmetric cryptography solves the connectivity challenge, start-up delay and network overhead are severe. The significant feature of the proposed method solves this delay challenge by aggregating many transactions into a block and fixing constraint range of multicasting blocks. Also, aggregating transactions of various end-users into a block preserves the path anonymity. The asymmetric cryptography with ring public and private keys protects the identity anonymity as well as unlinkability. The robust anonymity mechanism existence and the traceability of all transactions constitute the main advantages of the proposed method. The simulation is running by the python to evaluate blockchain performance in VANET with connectivity failure and rapidly changing topology. The results indicate the stabilization of the proposed method in the VANET environment.</p> 2020-06-26T23:03:56+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/6000 Pregnancy Outcomes in HIV-Infected Women: Our Experience at a Tertiary Health-Care Center, Ahmedabad, Western India 2020-07-01T20:20:47+00:00 Dr. Babulal Patel MD babu_patel007@hotmail.com Dr. Adwait B.

These parameters are the most important soil parameters, necessary to be known before each building project. The undisturbed soils samples are taken at nine different points labeled as P1, P2... P9 at the depths varying from 5m to 9.5 m and distanced around 10 to 15 meters. These studies are motivated by the fact that in this region, mechanical properties of soil have huge effects on buildings. By plotting the void ratio as a function of the logarithm of the pressure, these mechanical parameters are found and compared to that obtained from the inner land of Cameroon, Yaoundé town chosen as an example. As a result, this comparison has allowed us to classify the soil and give some practical advantages when carrying out civil engineering works such as buildings, bridges in coastal area.</p> 2020-07-04T04:53:34+00:00 Copyright (c) 2020 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) https://asrjetsjournal.org/index.php/American_Scientific_Journal/article/view/6010 Children and Mothers' Preferences of Dentists’ Attire in Public Daycare Centers 2020-07-09T06:21:10+00:00 Rise Consolação Iuata Costa Rank riserank@yahoo.com.br Joana Estela Rezende Vilela joanaerv@yahoo.com.br Aline Peixoto Oliveira Santos marjorieodontoped@gmail.com Marjorie Freitas Ávila marjorieodontoped@gmail.com Iara Priscilla Inacio de Freitas ivanrank@yahoo.com.br Rafaela Maynart Batista ivanrank@yahoo.com.br Tatiana Soares Lima marjorieodontoped@gmail.com Ivan Iuata Rank ivanrank@yahoo.com.br Juliana Batista da Silva julianabstvet@gmail.com Rafaela Cristina da Silva Xavier rafaelacristina_sx@hotmail.com Walmirton Bezerra Dalessandro walmirton@hotmail.com Fábio Pegoraro professorpegoraro@yahoo.com.br Vinicius Marinho vinicius.marinho22@gmail.com Wataro Nelson Ogawa wspin7@gmail.com <p>According to the environment and appearance of the professional in the dental office, the child may have different emotional reactions.
