Developing Energy Aware Distributed Aggregation Tree Technique for Wireless Sensor Networks
Authors: Al-Mejibli Intisar
Published: April 2020

Wireless sensor network WSN consists of small sensor nodes with limited resources, which are sensing,

gathering and transmitting data to base station. Sensors of various types are deployed ubiquitously and widely in varied

environments for instance, wildlife reserves, battlefields, mobile networks and office building. Sensor nodes are having

restricted and non replenishable power resources and this is regarded as one of the main of their critical limits. All

applied techniques and protocols on sensor nodes must take into consideration their power limitation. Data aggregation

techniques are used by sensor nodes in order to minimize the power consumption by organizing the communication

among sensor nodes and eliminating the redundant of sensed data. This paper proposed lightweight modification on data

aggregation technique named Energy Aware Distributed Aggregation Tree EADAT. The main principle of this

development is using the available information in sensor nodes to pass the role of parent node among sensor nodes in

each cluster. The process of passing parent node role is based on nominating the sensor nodes which have higher power

on regular bases. A model based on tree network architecture is designed for validation purpose and is used with NS2

simulator to test the proposed development. EADAT and EADAT with proposed development are applied on the designed

model and the results were promising

Published: April 2020

Information Retrieval (IR) is a field of computer science that deals with storing, searching, and retrievingdocuments that satisfy the user need. The modern standard Arabic language is rich in multiple meanings (senses) for manywords and this is substantially due to lack of diacritical marks. The task for finding appropriate meanings is a key demand inmost of the Arabic IR applications. Actually, the successful system should not be interested only in the retrieval quality andoblivious to the system efficiency. Thus, this paper contributes to improve the system effectiveness by finding appropriatestemming methodology, word sense disambiguation, and query expansion for addressing the retrieval quality of AIR. Also, itcontributes to improve the system efficiency through using a powerful metaheuristic search called Harmony Search (HS)algorithm inspired from the musical improvisation processes. The performance of the proposed system outperforms the one inthe traditional system in a rate of 19.5% while reduces the latency in an approximate rate of 0.077 second for each query.

Authors: Jasim Sarah
Published: April 2020

There is a significant necessity to compress the medical images for the purposes of communication and storage.Most currently available compression techniques produce an extremely high compression ratio with a high-quality loss. Inmedical applications, the diagnostically significant regions (interest region) should have a high image quality. Therefore, it ispreferable to compress the interest regions by utilizing the Lossless compression techniques, whilst the diagnostically lessersignificant regions (non-interest region) can be compressed by utilizing the Lossy compression techniques. In this paper, a hybridtechnique of Set Partition in Hierarchical Tree (SPIHT) and Bat inspired algorithms have been utilized for Lossless compressionthe interest region, and the non-interest region is loosely compressed with the Discrete Cosine Transform (DCT) technique.The experimental results present that the proposed hybrid technique enhances the compression performance and ratio.

Published: April 2020

Fifth−generation (5G) and millimeter−waves (MM−W) hold tremendous promise to provide opportunities torevolutionize education, healthcare, business, and agriculture.Nevertheless, the generation of MM−W in the electrical−domain is infeasible due to the bandwidth limitation of electronic componentsand radio frequency (RF) interference. The capability to generate MM−W in the optical−domain can provide transportation ofMM−W with low loss from switching center to remote base stations. The present paper is focusing on electro−opticalup−conversion (EOU) techniques for optical generation and transmission of 60−GHz MM−W signal. A comparative study iscarried out between three different EOU techniques: frequency−quadrupling, frequency sextupling and frequency−octotupling. The comparative study aims at showing the strengths and weaknesses of three EOU techniques and evaluatingeach technique in terms of electrical spurious suppression ratio (ESSR), as well as in terms of the influence of non−ideal phaseshifting. The performance of the three EOU techniques after transmission over optical fiber is evaluated by eye pattern test. Theresults of the simulation confirm that the frequency−quadrupling outperforms frequency− sextupling and frequency− octotuplingtechniques.

Authors: J. Murnisyazwani , M.S. Rabeta
Published: April 2020

This study evaluates the antioxidant and antimicrobial activity of sapodilla fresh, juice and
bar using three extraction solvents with different polarities (70% acetone, 80% ethanol and
water). For evaluating antioxidant capacity, Ferric Reducing Antioxidant Power (FRAP)
and 1,1-Diphenyl-2-Picrylhydrazyl (DPPH) assays were used. The total flavonoid content
(TFC) and condensed tannin of the sapodilla juice and bar extracts were determined as
well. Antimicrobial activity was measured using Staphylococcus aureus, Salmonella spp.,
Escherichia coli and Bacillus subtilis. Both sapodilla bar and juice produced more
inhibition of the DPPH assay with 70% acetone and 80% ethanol than with the water
extraction. The reducing ability of fresh sapodilla was on the order of 70% acetone > 80%
ethanol > water. The 70% acetone was the best solvent for yielding condensed tannins. For
total flavonoid content, fresh sapodilla and the sapodilla bar and juice showed the highest
flavonoid content in 80% ethanol. The results showed that the 70% acetone extract for
sapodilla bar and juice exhibited stronger antibacterial activity against gram-positive
bacteria. Despite some antioxidants being lost in processed food, these still retained
important sources of bioactive compounds. Antimicrobial activity done showed different
selectivity for sapodilla juice and bar.

Authors: Wan Mohamad Din W.N.I. , Mohd Zin Z. , Abdullah M.A.A. , Zainol M.K.
Published: April 2020

Every good food comes with its negative side, and ‘Kacang Koro’ is one of them.
Although ‘Kacang Koro’ contains a lot of protein, it also has a negative side, such as an
anti-nutritional factor. These anti-nutrient factors need to be removed in order to produce
nutritious food. This study was aimed to determine the effect of pre-treatment (soaking,
soaking-boiling, soaking-roasting, soaking-microwave) on physicochemical composition
and sensory acceptability in ‘Kacang Koro’ energy bar. The energy bars were subjected to
physical analyses, proximate analysis, calorie content, phytochemical analyses and
sensory analysis. All the different treatments of ‘Kacang Koro’ energy bar showed
moisture content of 8.29 - 12.42%, ash of 1.09 - 1.11%, crude protein of 7.51 - 10.14%,
crude fat of 12.75 - 17.77%, crude fibre of 2.78 - 3.62%, and carbohydrate of 57.19 -
63.91%. The calorie content was found to be 484.81 - 511.29 kcal/100 g. The oxalate
content in all ‘Kacang Koro’ pre-treated is ranged between 29.81 - 45.1 mg/kg. The phytic
acid content is between 0.15% - 0.37% and the tannin content is in the range of 25.53 L -
52.30 mg GAE/L. Energy bar with soaking-microwave pretreated ‘Kacang Koro’ has
higher value in crude protein, crude fat, and crude fibre but moderate in moisture and
carbohydrate content, meanwhile lower in ash content. Sensory acceptability tests showed
the sweetness, taste and overall acceptability of the samples were significantly different
between ‘Kacang Koro’ energy bars using soaking compared to soaking-microwave pretreatment. The pre-treatment of ‘Kacang Koro’ may boost the use of these ‘Kacang Koro’
in the food industry and promote their application.

Published: April 2020

The genus Campomanesia belongs to the Myrtaceae family and has about 30 species. It is characterized by citrus-flavored fruits. Several articles describe the extensive use of its fruit, such as in the food industry, however, other parts of the plants are also used for food or pharmacological purposes such as the leaves, flowers, seeds, and roots. Analyzing works published on the genus in the period 2005-2019, we observed that the classes of main flavonoid compounds present are anthocyanins, chalcones, coumarins, tannins, and saponins. Species of this genus are also used as a medicine in the treatment of wounds, toothaches, fractures, and bruises.  Therapeutic activities have also been detected for Campomanesia, such as antimicrobial, antiulcerogenic, antiprotozoal, anti-inflammatory, and antidiarrheal activity, antiproliferative and antioxidant potential, antiplatelet, antithrombotic, and fibrinolytic activities, as well as hypotensive effects. There are a small number of works demonstrating the low toxic potential of plant extracts. Thus, the Campomanesia genus presents pharmacological potential to be explored.

The determination of the estrogenic mycotoxins in water samples from the Rico Stream microbasin yielded levels of up to 59 ng L-1 and their corresponding calculated estrogenic equivalent (cEEQ) values were between < 0.03 and 1.4 ng L-1, which are associated with negative effects on the reproduction and growth of some fish species. The physicochemical and microbiological parameters were evaluated to determine the water quality in the Rico stream region. This study revealed the first data about the presence of estrogenic mycotoxins in the Brazilian river waters and emphasizes the need to include these substances in future public policies concerning water quality, since these compounds are not yet legally regulated. From an environmental aspect, it is necessary to take into account the continuous introduction into surface water of microcontaminants associated with wastewater effluent, such as estrogenic mycotoxins.

Aiming to evaluate the effects of Solanum sisymbriifolium extracts on the development of Spodoptera frugiperda, a leaf dichloromethane extract was obtained and subjected to further purification following a bioguided methodology. The structure of the two main compounds isolated from S. sisymbriifolium Type IV glandular trichomes have been completely elucidated by a combination of chemical and spectroscopic methods. They are glycosides of 3-(R)-hydroxypalmitic acid and xylo (β-1-5) furanoarabinoside (Compound 1) and its 3-O-palmitoyl derivative (Compound 2). These compounds greatly influenced the survival and the development of S. frugiperda, when compared to an in vitro test control. The extracts delayed the development, decreased survival and promote abnormalities in the immatures (larvae and pupae). They also showed increasing toxicity towards S. frugiperda in the purification following a bioguided fractionation. The pure compounds had the most deleterious activity, increasing the larval and pupal toxicity (100% mortality for Compound 2 at 2.50 mg mL-1 and 90% mortality for Compound 1 at 1.00 mg mL-1).

Published: April 2020

In this work, nine different biodiesels were obtained by transesterification reaction with three types of vegetable oils and three variant alcohols. The objective was to analyze them physicochemically before and after they went to the engine, to know if they had the necessary properties to act as lubricants. Subsequently, the same biodiesels were analyzed in the engine in order to observe the behavior of their dynamic viscosities, to evaluate if they were similar or superior to commercial lubricants. It was possible to note that all biodiesel produced are within the National Agency for Petroleum, Natural Gas and Biofuels (ANP) legislation and presented as potential lubricants, due to the kinematic viscosity behavior when compared before and after the engine. These results made them possible replacements for commercial lubricants, besides having greater advantages for the engine and the environment. However, although coconut oil-derived biodiesel has good yields, it is not promising because, at temperatures below 25 °C tends to solidify, causing short, medium- and long-term engine parts wear.

Published: April 2020

Petroleum exploration, as well as environmental impacts descendant of aquatic contaminations involving sea oil spills, foments the development of new technologies of marine ecosystems protection. Acknowledged like the most abundant polymer available today worldwide, cellulose is a linear 1.4-β-glucan, composed of D-anhydroglucopyranose units, linked together by β-(l→4)-glycosidic bonds. In this study, a chemical modification route of the cellulose polymer was accomplished using glycidyl methacrylate and stearin to test its oily adsorption capacity of soybean, diesel, and residual oils. Scanning Electron Microscopy (SEM) and Fourier-Transform Infrared (FT-IR) Analyses were applied to the characterization of the morphological and functional structure of microcrystalline cellulose. The results obtained proved the reach of an average hydrophobicity grade of 78.3±0.9% and a mass gain of MG = 2.89%, suggesting the possible insertion of hydrophobic groups onto the cellulose molecule and corroborating the hypothesis of successful grafting of glycidyl methacrylate and stearin onto the polymer. The oily adsorption tests showed a satisfactory capacity of the modified cellulose to adsorb small amounts of viscous oils, like residual oil.

Authors: Styszyński Marcin
Published: April 2020

Niniejszy artykuł dotyczy analizy i porównania środków retorycznych zawartych w oficjalnych oświadczeniach publikowanych w latach 2016-2019 przez strony zaangażowane w konflikt jemeński, który stanowi arenę rywalizacji politycznej, militarnej i gospodarczej między dwoma mocarstwami regionalnymi: Królestwem Arabii Saudyjskiej i Islamską Republiką Iranu. Zaprezentowane badania wskazują, że zarówno koalicja zbrojna pod przywództwem Arabii Saudyjskiej, jak i rebelianci jemeńscy wykorzystują rozgrywające się wydarzenia do budowy swojego pozytywnego wizerunku i potępienia przeciwnika. Zasadniczą rolę w tym kontekście odgrywają odpowiednie środki retoryczne kształtujące emocjonalny charakter przekazu wpływający na opinię publiczną i jej poparcie dla danej strony konfliktu.
Subjective Basis for Elucidating Communication in the Personalistic Perspective
Authors: Gondek Paweł
Published: April 2020

The paper examines man’s involvement in the communication process. While elucidating communication one needs to take into account the subjective factors which condition its existence. The article particularly highlights the personal dimension of human existence and an integrated action of his powers thanks to which man constitutes the subject and motive for all forms of communication activity. The basic types of communication are affected by virtue of a relation to human powers: intellective-cognitive and volitive-emotive. Yet, it is persuasive communication that, methodologically ordered within the framework of rhetoric, seems to fully recognize the communication determinants characteristic of man’s nature. The progressing technicization of the media also needs to be perceived through an integrated personalistic perspective accepting the subjective determinants of man participating in the communication process.
