BAND NOTCHED UWB MIMO/DIVERSITY ANTENNA DESIGN WITH INDUCTANCE BOOSTED COMPACT EBG STRUCTURES

A triple band notch MIMO/Diversity antenna using Inductance Boosted Compact Electromagnetic Band Gap (IB-CEBG) cells is presented in this paper. For obtaining compactness in the conventional EBG cell, spiral shaped defects are introduced. The proposed antenna obtains triple band notches in WiMAX (3.3–3.6 GHz), WLAN (5–6 GHz), and the X-band satellite communication (7.2–8.4 GHz) bands. IB-CEBG cells exhibits miniaturization of approximately 46% for WiMAX band, 50% for WLAN band and 48% for X-band Satellite communication band, compared to conventional EBG cells. To enhance the isolation among all four compact UWB monopoles, rectangular slots in the ground plane and parasitic decoupling arrangement are utilised. Further, a stepped structure with an angular separation of 90◦ is incorporated with individual monopoles to reduce mutual coupling effects. Stepped structure also helps in the better impedance matching by incrementing the path length. The results show that the magnitude of transmission coefficient is greater than 15 dB in between the ports of proposed antenna elements. Envelope Correlation Coefficient is less than 0.5, which lies in tolerable limits for Ultra-Wide band (UWB) frequency range. It has been noticed that notched frequency is dependent on IB-CEBG cell parameters. The proposed antenna is fabricated using an FR-4 substrate with overall dimensions of 58 × 90 × 1.6 mm3.
GROWTH, YIELD AND FRUIT QUALITY TWO CUL-

The hybridisation of Vaccinium angustifolium with Vaccinium corymbosum has led to several cultivars which are also known as Lowbush or Half-highbush blueberry. The appearance, taste and chemical composition of their fruits are reminiscent of those from wild varieties of Vaccinium angustifolium. The research was conductedat the Research Station of the Laboratory of Orchard at the West Pomeranian University of Technology in Szczecin. The plant height, size, yield, quality and the chemical composition of fruits of Lowbush blueberry bushes (‘Emil’ and ‘Putte’) were determined. Lowbush blueberry bushes were planted at distances of 1.0 × 2.5 m in acid muck soil (peat) at the Research Station of the Fruit Farming Department in 2005. Six-year-old bushes were characterized by a relatively low height, 70 cm on average; however, ‘Putte’ cultivar plants were slightly bigger. They also rendered a higher yield, totalling to 1401 g over the 4 years of research. On average, 100 g of fruits were collected from one bush in the first year and 600–700 g in the last year. Moreover, fruits from these bushes were characterized by a higher content of extract, organic acids and polyphenolic compounds, among which anthocyanins constituted the largest group. ‘Emil’ cultivar fruits were bigger and firmer than fruits of ‘Putte’ cultivar.
Research on DNA Extraction Methods from a Single Nematode

To explore an efficient,stable,low-cost DNA extraction method from single nematode for the support of molecular identification of nematodes,using six species of plant-parasitic nematodes as experimental materials, four DNA extraction methods,namely,direct lysis method,freeze-thaw lysis method,cutting lysis method,freeze-thaw cutting lysis method were designed and compared in order to check their efficiency of DNA extraction from single nematode. The results showed that cutting lysis method and freeze-thaw cutting lysis method were the most efficient and stable methods for DNA extraction of single nematode,then the freeze-thaw lysis method,and the direct lysis method was the worst one. Total DNA with high-quality from a single nematode could be gained efficiently and stably through two methods,namely,cutting lysis method and freeze-thaw cutting lysis method. And the extracted DNA meeted requirement of the following PCR amplification.
Sputtering Yield in Nanowires

Ion irradiation allows to modify nanoparticles and nanostructured surfaces; therefore, it is a widely used technique to adjust the properties of these materials [1]. Sputtering is one of the most important effects induced by irradiation. In nanosystems, this effect is strengthened due to the higher surface-to-volume ratio [2]. This article is focused on its analysis in nanowires. Recently, Urbassek et al. [3] have showed that the bombardment of convex surfaces produces an increasing of sputtering yield. Therefore, the issue is whether curvature explains sputtering yield for all sizes. In this work, we use <110>-oriented Co nanowires bombarded with 1-keV Ar ions with different curvature: circular, square and rhomboid cross sections were used to analyse its influence. In addition, given that the crosssection size can also modify sputtering yield, results for different nanowire widths (nanowire length transversal to the bombardment direction divided by 2) were analysed. Next, we shows some results that the simulation and theoretical models predict. A deeper reasoning with detailed proofs will be published shortly.

(Received 28/07/2020, accepted 20/09/2020) DOI: 10.21608/ejoh.2020. 36542.1139 ©2020 National Information and Documentation Centre (NIDOC) THE goal was to evaluate the response of pomegranate cultivar transplants “Manfaluty” and “Wonderful” for salinity stress. A pot investigation was conducted during (2016 and 2017) seasons in a glasshouse, Faculty of Agriculture, Ain Shams Univ., Shoubra ELKheima, Egypt. Pots were arranged in a randomized complete design with two factors, the first one was pomegranate cultivars which included two cultivars namely (Manfaluty and Wonderful) and the second factor was NaCl levels whereas, transplants were irrigated with five levels of water salinity (0, 20, 40, 60, and 80 mM NaCl). It could be summarized results in some main points:
A study of the increased temperature influence on the electrochromic and electrochemical characteristics of Ni(OH)2-PVA composite films

Electrochromic devices, as an element of “smart” windows, can be exposed to extreme temperatures due to their purpose and location. Exposure to high temperatures can change the characteristics of electrochromic devices and lead to malfunction. The present study is intended to fill in the gaps related to the stability of electrochemical and electrochromic parameters of one of the known materials – nickel hydroxide (II). The present study highlights changes in some physico-chemical characteristics that occur during prolonged exposure to high temperature in different media. Ni(OH) 2 -polyvinyl alcohol, prepared using the cathodic template method, was aged at 80 °С under the air atmosphere and in the working electrolyte solution – 0.1 М KOH for 8 hours. The temperature was chosen based on the maximum registered temperature on Earth, possible film heat up and possible rapid degradation of electrochromic films. As a result, it was found that degradation does occur in a basic solution, while on air some improvement was observed instead. The authors propose the mechanism that explains experimental results, which lies in “ageing” of active material Ni(OH) 2 . The latter occurs in the active mass of alkaline batteries. Possible methods for preventing degradation are also proposed, which can be realized with the use of thickened electrolytes or special films that are deposited onto the electrochrome
Complementarity of Strategic Assets: A Symbiotic Evolutionary Model for Open Innovation

This article proposes a theoretical model that simulates the propensity to establish mutualistic symbiotic relationships between corporations and startups on open innovation programs. Inspired by the concept of symbiosis, the Evolutionary Model of Symbiotic Relationships for Innovation identifies the pairs with the major complementarity of strategic assets necessary for the generation and capture of the value of innovation projects and determine if this relationship promotes gains for both parties. The model has been applied in a single case study, subunits of analysis incorporated. The results show a correlation between the propensity indicated by the model and the selection actually performed.
PID Controller Design for Two Link Flexible Manipulator

Flexible Link Manipulator Systems (FLMs) is more favoured in the industries when compared to the rigid link manipulator, the reason for this include: their light weight, the ease with which they can be manipulated, they consume less energy because of their light weight, and they can be manipulated faster when compared to their rigid counterpart. Despite all these advantages, controlling flexible system can pose a lot of challenges because of the distributed nature of such flexible systems. In this research work, a traditional proportional, integral derivative (PID) control system was designed for two-link flexible manipulator. The two-link robot manipulator was modelled using Lagrange and assumed mode method. The control law was developed and tested in Matlab/Simulink environment. The performance of the designed controllers is evaluated in terms of input tracking capability, energy utilization, and deflection suppression and vibration control. This study shows that a simple traditional PD/PID controller can be effectively designed for two link flexible manipulators for point to point motion control and vibration suppression.
Student Emotional Responses to Different Communication Situations

Communication and emotion are closely linked. Emotions experienced while communicating with others can affect one’s message both verbally and nonverbally. This study asked participants to identify the emotions they experienced when communicating with groups of different sizes. These emotions were drawn from, and displayed upon, the Circumplex Model of Affect, a figure developed by Posner, Russell, and Peterson (2005). This model divides 16 emotions into quadrants that lie along two axes: pleasantness and emotional arousal. Results show that as audience size increases, speakers’ emotions become more unpleasant, more highly aroused, and more variable overall. Prior research indicates that these negative emotions can have detrimental effects not just on the speaker’s message, but also on how the audience receives that message. Helping communicators understand the link between their emotions and their communication is a valuable step in improving communication ability and developing valuable emotional intelligence skills.
Developments in Cellulose based Insulating Kraft Paper for Liquid Immersed Power Transformers

Cellulosic materials such as paper have been used in the insulation system of power transformers for a long time due to their ease of manufacture and economical as compared to other materials. But the major disadvantage of cellulosic material for electrical use is its hygroscopic nature which needs to be maintained dry. To conquer this limitation, a new area to look forward is mixing of cellulose fibers with artificial fibers. The current paper discusses the development of cellulose based electrical grade insulating paper for use in transformer, improvements/up-gradations made and particularly the employment of synthetic fibers to extend cellulose based insulation life and successively increase the lifetime of transformer.

Search-tree Based SDN Candidate Selection in Hybrid IP/SDN Network

The link failure recovery is important to the Internet. For improving the performance of link failure recovery in the IP network, the software defined networking (SDN) is applied to achieve this target. The SDN is effective on solving this kind of issue. However, considering the deployment cost, only a few IP routers can be replaced by the SDN switches. Thus, to minimize the number of SDN switches, the greedy-based approach is proposed to select the most appropriate deployment locations. But the greedy-based approach has disadvantages. For addressing these disadvantages, in this paper, we proposed the search-tree based SDN candidate selection (SCS) algorithm. In this algorithm, for achieving better performance than the greedy-based approach, three algorithms are proposed, which are the search-tree based feasible solutions calculation algorithm, the most appropriate feasible solution selection algorithm, and the most appropriate designated SDN switch selection algorithm. Based on these algorithms, the performance of the search-tree based SCS algorithm is improved greatly compared with the greedy-based algorithms.
Management of Potato Late Blight (Phytophthora infestans) by the Combination of Potato Variety with Different Fungicide in Horo Guduru Wollega Zone

Potato (Solanum tuberosum L.) is one of a major crop produced globally and serves as a source of food. Ethiopia is one of the major potato producers in Africa, with 70% of its arable land in the high-altitude areas between 1,500-3,000 meters being suitable for potato production. Late blight, caused by P. infestans, is a devastating disease of potato worldwide. In highlands of western Ethiopia especially at Horo Guduru Wollega Zone Potato late blight caused by Phytophthora infestans is a bottleneck for potato production. Integrated management to control devastative pathogen was carried out and three cultivars of potato (Gudene, Jalane and Belete) were used in this experimental study. A randomized complete block design with three replications was employed in a factorial arrangement at Gitilo and Harato research site of Wollega University. Each potato variety including local check was applied with fungicide at different times. Disease incidence and severity was examined with the first appearances of the first late blight symptoms; each plant appearances was visually examined on each plots. The effect of variety and fungicide combinations on disease severity data was integrated into area under disease progress curve. Analysis of Variance (ANOVA) was performed to disease parameters (Disease incidence, Disease severity and AUDPC) and yield parameters using Statistical Analysis System (SAS). Gudane variety was relatively resistant as compared to the rest of the varieties during the main growing season at Gitilo and Harato site.
MANUFACTURING PROCESS OF CAR SPOILER PRODUCT USING CONTINUOUS RATTAN FIBER COMPOSITE MATERIALS

This study aims to develop the process of manufacturing car spoiler products using continuous rattan fiber composite materials. Rattan fiber was chosen because of its good strength, abundant availability in Indonesia and inexpensive price. The study was conducted by testing the strength of a composite rattan fiber, simulation using computer software, comparing with pre-existing spoilers and making prototypes of spoilers. Based on the results of the study, the strength of continuous rattan fiber composite materials with polymer matrix is as follows: maximum tensile strength of 27 MPa, maximum compressive strength of 44 MPa, maximum flexural strength of 46 MPa, and maximum impact strength of 29 kJ/m 2 . As a comparison, ABS plastic material used in many car spoilers has a maximum tensile strength of 35 MPa, a maximum compressive strength of 48 MPa, a maximum flexural strength of 56 MPa, and a maximum impact strength of 31 kJ/m 2 . From the results of the simulation of loading using software carried out on the composite material of polymer rattan fibers, we obtain a compressive strength of 2000 N load of 51 MPa with compressive strain of 0.00873 mm/mm. From the results of simulation loading using software carried out on ABS plastic material, we obtain a compressive strength for the 20110 N load of 48 MPa. The manufacturing process has produced a prototype of spoilers that are ready to use with good results. The results of this study will be a reference for the next development.
GLOBAL DYNAMICS OF A TWO-STRAIN HIV INFECTION MODEL WITH INTRACELLULAR DELAY

In this paper, we formulate a mathematical model to describe the interaction of two strains of HIV virus and the target cells within a host. The model is in the form of delay differential equations with two discrete delays to account for the average time for replication for the two strains. The model dynamic turns to be generically determined by two composite parameters R1 and R2, the basic reproduction numbers for strain 1 and strain 2, respectively in the absence of the other strain, in the sense that except for the critical case R1 = R2 > 1, the solutions are proved to converge to the corresponding equilibrium globally. The method used is Lyapunov functionals.
Legilimens: An Agile Transport for Background Traffic in Cellular Networks

Large data transfers can result in significant congestion and performance degradation for interactive end-user applications such as web browsing and streaming. While there are existing TCP congestion control algorithms for delivery of large volume data (e.g., LEDBAT, TCP-LP), our results show that these protocols are not effective in cellular networks due to variability in radio channel conditions and the use of cellular schedulers in base stations. We propose Legilimens, an agile TCP variant for cellular downlink transfers, which not only retains desirable properties of existing approaches, but also exploits the properties of the cellular schedulers to estimate load and capacity and addresses the challenges in cellular networks. As a result, Legilimens is able to deliver traffic using only the spare capacity on the downlink. We conduct extensive evaluations of Legilimens in multiple settings—in a large cellular network for real-world performance, on the PhantomNet emulator for controlled experiments, and ns-3 simulator for scaled experiments—all of which demonstrate that Legilimens is superior to existing protocols in transferring large volumes of data without interfering with regular user traffic. Compared to existing low-priority protocols, Legilimens improves the throughput of background flows by 2x on average (up to 5x) without degrading the performance of foreground flows across all the three testbeds.
The amino acid residues phe76‐val96 of KL aligned closely with residues asp7‐asn27 of Aβ. Cross‐species comparison of KL revealed a high degree of alignment and conservation

The cause of Alzheimer's disease (AD) is poorly understood. In 1991, the amyloid hypothesis postulated that β‐amyloid (Aβ) accumulation is a key element. It follows that clearing the brain of Aβ would be beneficial, which has not been the case. Therefore, Aβ is likely a result, not a cause, of AD and may be protective rather than harmful. The apolipoprotein E4 (apoE4) allele is the strongest genetic risk factor for AD. Klotho (KL), encoded by the KL gene, may be another AD‐related protein. FGF21 is a circu‐ lating endocrine hormone, mainly secreted by the liver, mostly during fasting. FGF21 acts by binding to its receptor FGFR1 and co‐receptor β‐klotho. FGF21 is neuroprotective and could delay onset of AD. In the present study, the KL protein structure was examined to determine whether it may interact with Aβ. Protein data bank (pdb) entries for klotho and Aβ were searched on the RCSB Protein Data Bank for β‐KL and AD amyloid β‐peptide. The protein structures were superimposed and aligned on PYMOL v2.3. 4 with the super command, which super aligns two protein selec‐ tions. To evaluate the conservation and alignment of the Aβ and KL genomes across species, BLAT, the Blast‐Like Alignment Tool of the UCSC Genome Browser, was used. The amino acid residues phe76‐val96 of KL aligned closely with residues asp7‐asn27 of Aβ. Cross‐species comparison of KL revealed a high degree of alignment and conservation in the chimp and 27 other primates; however, less align‐ ment and conservation were observed in the mouse, dog and elephant, even less in the chicken, western clawed frog (Xenopus tropicalis), zebrafish and lamprey. The current finding of amino acid residues phe76‐val96 of klotho aligning closely with residues asp7‐asn27 of Aβ suggests that Aβ can enhance the ability of klotho to draw FGF21 to regions of incipient neurodegeneration in AD. The problem arises with age. Older individuals do not heal or repair tissue damage as well as younger individuals. As neurodegeneration advances in an older individual, perhaps caused by neuroinflammation related to herpes simplex virus type 1, increasing amounts of amyloid are produced, forming an adhesive web, as the brain tries to hold the pathologic process in check. Meanwhile, the damage increases and spreads. Progressive neurodegeneration and cognitive decline are the outcome.
CypherDB: An Encryption Technique for Secure Database Processing

– Security models are the basic theoretical tools to start when developing a security system. This seems to be an issue which is insufficiently understood and it may be an explanation for the actual security crisis of information system. Most cooperation try to address there security problem by simply patching their system to eliminate identified vulnerabilities. In most cases, this is already too late and long term strategy. CypherDB addresses the problem of protecting the confidentiality of database stored externally in a cloud and enabling efficient computation over it to thwart any curious-but-honest cloud computing service provider. It works by encrypting the entire outsourced database and executing queries over the encrypted data.
Optimal Control Strategy for a Marine Current Farm Integrated with a Hybrid PV System/Offshore Wind/Battery Energy Storage System

This paper suggests an automated control technique constructed on the Multi-Objective Particle Swarm Optimization to enhance the operation of a wind farm, a marine power plant and a photovoltaic array with a battery energy storing system. due to changes in PV / wind / tide, and to boost the efficiency of offshore wind farms and marine power stations connected to the battery-powered storage system, with a view to smoothing power production, the aim of projected automatic control strategy is to minimize power fluctuations and voltage variations. The battery energy storage network was used with an optimized demand response strategy based on the real-time pricing model to improve stability and power efficiency, reduce the power fluctuations and variations in bus voltage and address renewable energy generation instability. The multi-objective particle swarm optimization-based energy management programming model would be used to minimize running costs, pollutant emissions, increase the demand response benefits of micro grid operators and, at the same time, meet the load demand constraints from customers of all sorts, such as domestic, commercial and industrial users.
