Potential of Anthill Soil as a Pozzolan in Concrete

Cement is the most utilised construction material and the second most consumed commodity in the world after water. It has been reported that the heavily energy-intensive processes that are involved in its production account for about 7 to 10 % of the total global anthropogenic carbon dioxide (CO2), which is the main cause of climate change; and are also expensive economically. Energy and cost efficiency can however be achieved by reducing on the amount of clinker, and in its place utilising pozzolans, which require less process heating and emit lower levels of CO2. This research aimed to provide an original contribution to the body of knowledge by investigating Anthill Soil (AHS) for pozzolanic properties. Cement was replaced in concrete with AHS by weight using 5% increments by weight, from 0 to 30% at the point of need. Durability was investigated using the water absorption and sulfate tests. Results of the chemical analysis by X-Ray Diffraction (XRD) showed that AHS contained the chemical composition required for pozzolans, and the compressive strengths achieved were for classes that are listed by standards as being durable and suitable for structural applications. The behaviour of AHS in workability, density, gain in compressive strength over time, water absorption and sulfate tests were also consistent with the characteristics of pozzolans, leading to a conclusion that it may be suitable for use as a pozzolan to improve the properties of concrete, reduce on the harmful effects of cement production to the environment and lower the overall cost of concrete, allowing for the construction of low cost buildings.
Evaluation of in-vitro antioxidant property and total phenolic content of Zanthoxylum rhetsa fruit extracts

Zanthoxylum rhetsa (Roxb.) DC of family Rutaceae is used in many traditional medicines as a therapy for diabetes, spasmodic, diuretic and inflammatory complications. Many chemical constituents like terpenoids, xanthyletin, sesamin, alkaloids, flavonoids and sabinene that are present in this plant attribute to various medicinal activities. Different parts of fruit of Zanthoxylum rhetsa were analyzed for their antioxidant property and total phenolic content. The antioxidant property was estimated using DPPH (Diphenyl picryl hydrazyl) radical scavenging activities of various extracts of fruit, seed, and seed coat. The antioxidant property of the fruit, seed and the seed coat were compared with the standard antioxidant chemical constituents like Propyl gallate (PG) and butylated hydroxytoluene (BHT). The total phenolic content in Zanthoxylum rhetsa fruits was determined using FolinCiocalteau reagent. Gallic acid was used as a standard compound and the total phenols were expressed as mg/ml Gallic acid equivalent (GAE) using the standard curve equation: y=0.061x-0.002: R=0.998. The total phenolic content varied from 0.027±0.0019 to 0.0392±0.011 mg/mL GAE in various parts of fruit extracts. The study reveals that fruits of Zanthoxylum rhetsa could be used as a good source of natural antioxidants in pharmaceutical industry.
The application of computer-assisted semen analysis (CASA) technology to optimise semen evaluation. A review

Reduced sperm motility has been associated with lower fertility rates (Yániz et al., 2018). Motile and acrosome-reacted spermatozoa revealed a high percentage of the variation in fertility of the samples (Flowers, 2009). However, fertility is multifactorial and several factors including season may influence the outcome, number of sperms, time of copula before ovulation and seminal plasma profile (Vesseur et al., 1996), and it must be considered the female effect. Furthermore, functional and structural sperm parameters such as motility, kinematics, viability, acrosome and DNA integrity, mitochondrial function, morphology and morphometrics (Gosálvez et al., 2016) may be associated with the fertility process. Boars or bulls are not usually considered seasonal breeders; however, there may be seasonal variations in semen quality (Ibănescu et al., 2018). Variations in sperm parameters between summers and winters have been partially attributed to the changes in scrotal thermoregulation and heat dissipation mechanisms (Menegassi et al., 2015). Computer-assisted semen analysis (CASA) technology allows the automated and accurate measurement of motile patterns of individual sperms in the ejaculate (Amann and Waberski, 2014). However, this standardisation has never been performed from an integrative point of view. There are three main aspects to consider when optimising ABSTRACT. Currently, artificial insemination (AI) is the most applied technique for assisted reproduction in the livestock industry. The traditional analysis of seminal quality includes the evaluation of concentration and motility (total and progressive), the parameters on which the number of doses producible from an ejaculate is calculated. The introduction of automated sperm evaluation systems based on computer-assisted semen analysis (CASA) represented a revolution in the production of seminal doses and the knowledge in reproductive biology; however, this technology has been generally implemented without a critical analysis of its limitations and dependence on several methodological factors. In addition to the use of CASA technology, the estimation of kinematics and morphometry have been incorporated as novel parameters for sensitivity and reproducibility. AI has facilitated the rapid and universal dissemination of genetic material from a relatively small number of males. The CASA systems allow the analysis of a large number of sperm cells in a short time, thereby providing an array of quantitative data on kinematics and head sperm morphometry, thus making it possible to optimise the reliability of seminal analyses.

How Does the Entrepreneurs’ Financial, Human, Social and Psychological Capitals Impact Entrepreneur’S Success?

The literature has widely covered the factors that determine the success of entrepreneurial ventures from financial and organizational perspectives. This study intends to tackle how the Financial Capital, the Human Capital, the Social Capital, and the Psychological Capital of the Entrepreneur affect Entrepreneurial Success. Despite that the Financial, Human, and Social Capitals are extensively examined in the literature as they relate to entrepreneurial success, this paper will add the psychological capital of the entrepreneur and examine its effect on entrepreneurial success in Egypt. This study aimed to investigate the effect of Financial Capital, Human Capital, Social Capital, and Psychological Capital on Entrepreneurial Success using a cross-sectional survey. Respondents were the owners and founders of small and medium enterprises (SMEs) in Cairo, Egypt. The results revealed that Social Capital and Psychological capital had a statistical significance as well as a positive strong relationship with Entrepreneurial success, while the Financial Capital and the Human Capital had statistical insignificance as well as a positive weak to a very weak relationship with Entrepreneurial success respectively. The study findings suggested that entrepreneurial success is strongly connected to the intangible resources of the entrepreneur, which are Social Capital and Psychological Capital, and that the Psychological Capital had the highest impact on Entrepreneurial success. However, the impact of the Financial Capital and Human Capital on Entrepreneurial Success was statistically insignificant.
Design, Resource Management, and Evaluation of Fog Computing Systems: A Survey

A steady increase in Internet-of-Things (IoT) applications needing large-scale computation and long-term storage has lead to an overreliance on cloud computing. The resulting network congestion in the cloud, coupled with the distance of cloud data centers from IoT, contributes to unreliable end-to-end response delay. Fog computing has been introduced as an alternative to cloud, providing low-latency service by bringing processing and storage resources to the network edge. In this survey, we sequentially present the phases required in the implementation and realization of practical fog computing systems: 1) design and dimensioning of a fog infrastructure; 2) fog resource provisioning for IoT application use and IoT resource allocation to fog; 3) installation of fog frameworks for fog resource management; and 4) evaluation of fog infrastructure through simulation and emulation. Our focus is on determining the implementation aspects required to build a practical large-scale fog computing infrastructure to support the general IoT landscape.
Effect of chitosan-coated iron oxide nanoparticles against Biofilm-forming potential of Staphylococcus aureus isolated from food of animal origin

Antimicrobial resistance (AMR) and emergence of multidrug resistant (MDR) in Staphylococcus aureus, is a major public health concern worldwide. S. aureus causes life-threatening diseases due to production of biofilm, a mechanism responsible for spread of multidrug resistance. Humans are infected with resistant foodborne bacteria via the food chain from reservoir animals. The aim of current study was to analyze the effect of chitosan coated iron oxide nanoparticles (IONP) on biofilm formation. To quantify biofilm production the Crystal Violet (CV) assay and Microtitre test assay (MTA) was used. Biofilm analysis by CV assay showed inhibition when incubated with Chitosan-coated nanoparticles. Biofilm inhibition was range from 66.17-99.25%, 68.63-98.86%, 91.41-97.66% at concentration of 500mg/mL, 1mg/mL and 4mg/mL respectively. Results indicate that chitosan coated IONP were effective in restraining biofilm formation, have potential to be developed as therapeutic agent where antibiotics are non-effective or in combination with antibiotics and against antibiotics resistant strains.
DEFORMATION MONITORING USING SAR INTERFEROMETRY AND ACTIVE AND PASSIVE REFLECTORS

Abstract. This paper is focused on SAR interferometry for deformation monitoring, based on the use of passive and active reflectors. Such reflectors are needed in all cases where a sufficient response from the ground is not available. In particular, the paper describes the development of a low-cost active reflector. This development was carried out in an EU H2020 project called GIMS. The paper summarizes the key characteristics of the developed active reflector. The reflector was tested in two main experiments: the first one located in the campus of CTTC and the second one in a GIMS test site located in Slovenia. The experiments demonstrate the visibility of the active reflectors and provide the first results concerning the phase stability of such devices.
Seismic Tomographic Imaging of the Eastern Mediterranean Mantle: Implications for Terminal‐Stage Subduction, the Uplift of Anatolia, and the Development of the North Anatolian Fault

The Eastern Mediterranean captures the east‐west transition from active subduction of Earth's oldest oceanic lithosphere to continental collision, making it an ideal location to study terminal‐stage subduction. Asthenospheric‐ or subduction‐related processes are the main candidates for the region's ∼2 km uplift and Miocene volcanism; however, their relative importance is debated. To address these issues, we present new P and S wave relative arrival‐time tomographic models that reveal fast anomalies associated with an intact Aegean slab in the west, progressing to a fragmented, partially continental, Cyprean slab below central Anatolia. We resolve a gap between the Aegean and Cyprean slabs, and a horizontal tear in the Cyprean slab below the Central Anatolian Volcanic Province. Below eastern Anatolia, the completely detached “Bitlis” slab is characterized by fast wave speeds at ∼500 km depth. Assuming slab sinking rates mirror Arabia‐Anatolia convergence rates, the Bitlis slab's location indicates an Oligocene (∼26 Ma) break‐off. Results further reveal a strong velocity contrast across the North Anatolian Fault likely representing a 40–60 km decrease in lithospheric thickness from the Precambrian lithosphere north of the fault to a thinned Anatolian lithosphere in the south. Slow uppermost‐mantle wave speeds below active volcanoes in eastern Anatolia, and ratios of P to S wave relative traveltimes, indicate a thin lithosphere and melt contributions. Positive central and eastern Anatolian residual topography requires additional support from hot/buoyant asthenosphere to maintain the 1–2 km elevation in addition to an almost absent lithospheric mantle. Small‐scale fast velocity structures in the shallow mantle above the Bitlis slab may therefore be drips of Anatolian lithospheric mantle.
Mammalian Survey of Jiuzhaigou National Nature Reserve, Sichuan Province

From 2003 to 2004,the mammal fauna of the Jiuzhaigou National Nature Reserve was surveyed. Six separate surveys were conducted during this period. A summary of these collections showed that there are 78 species mammals in the Jiuzhaigou National Nature Reserve. An investigation of the biogeographic origin of this mammal fauna indicates that 50 species belong to the Oriental realm, 25 species belong to the Palaearctic realm, and 3 species are widely distributed. Ten general patterns of distribution were noted among the 78 species of mammal. This reserve's mammals show a very high south-north penetrability and antiquity.Twenty species in this reserve have been identified as nationally protected rare mammals; six of the species are first grade protected rare mammals. In addition, there are many rare small mammals in the reserve, such as the China jumping mouse(Eozapus setchuanus), Chinese Dormouse (Chaetocauda sichuanensis) and Bedford's vole (Proedromys bedfordi). There is a distinct trend for an increasing proportion of Palaearctic mammals and decreasing proportion of Oriental mammals as one ascends from 2 000 - 3 600 m . However, 3 200 - 3 600 m there is an abundance of both Palaearctic and Oriental species. These results show that this mammal fauna is broadly in transition in this area, including at elevations above 3 200 m.
Time-Splitting Coupling of WaveDyn with OpenFOAM by Fidelity Limit Identified from a WEC in Extreme Waves

Survivability assessment is the complexity compromising Wave energy development. The present study develops a hybrid model aiming to reduce computational power while maintaining accuracy for survivability assessment of a Point-Absorber (PA) Wave Energy Converter (WEC) in extreme Wave Structure Interaction (WSI). This method couples the fast inviscid linear potential flow time-domain model WaveDyn (1.2, DNV-GL, Bristol, UK) with the fully nonlinear viscous Navier–Stokes Computational Fluid Dynamics (CFD) code OpenFOAM (4.2, OpenFOAM.org, London, UK). The coupling technique enables the simulation to change between codes, depending on an indicator relating to wave steepness identified as a function of the confidence in the linear model solution. During the CFD part of the simulation, the OpenFOAM solution is returned to WaveDyn via an additional load term, thus including viscous effects. Developments ensure a satisfactory initialisation of CFD simulation to be achieved from a ‘hot-start’ time, where the wave-field is developed and the device is in motion. The coupled model successfully overcomes identified inaccuracies in the WaveDyn code due to the inviscid assumption and the high computational cost of the OpenFOAM code. Experimental data of a PA response under extreme deterministic events (NewWave) are used to assess WaveDyn’s validity limit as a function of wave steepness, in order to validate CFD code and develop the coupling. The hybrid code demonstrates the applicability of WaveDyn validity limit and shows promising results for long irregular sea-state applications.
Progress of researches on induced resistance of plant activator

Plant activator (also called elicitor) itself and its metabolites have no fungicide activity in vitro, but they can induce plant immunity system to produce systemic acquired resistance (SAR) against a wide spectrum of pathogens persistently.Apart from accumulation of lignin in cell wall by increase of hydroxyproline rich glucoproteins (HRGP) induced by elicitor,increase of endogenesis salicylic acid (SA),oxidative burst, hypersensitive response (HR) caused by programmed local cell death could also be observed in the elicited plants.The persistent SAR against a wide spectrum of pathogens only occurred after the changes of circum- stantial resistant enzymes and substances such as phenylalanine ammonialyase (PAL),β-1,3-glucanase, chitinase,peroxidase(POX),lignin and phytoalexins et al.caused by a series of regulation of plant guard gene expression through pathogenesis resistance signaling pathways conducted by endogenesis signaling com- pounds SA,jasmonic acid(JA),ethylene(Et)and nitrogen oxide(NO). In this paper,the conception, characteristics,category and mechanism of the mode of action of plant activator were discussed.The prospects and directions of application and development of plant activator were mentioned.The possible problems and the corresponding methods for settlement were also being put forward.
A Final Report on Investigation of Wildlife Trade in Myanmar-Thailand Border Cities under Growing Trans-boundary Economic Trade

Investigation of Wildlife Trade in Myanmar-Thailand Border cities under Growing Transboundary Economic Trade was conduct one years (March 2016 to March 2017). Tachilek and Myawaddy were focused as two main study cities on the border with Thailand. Items observed at the survey site included animal skins, whole animals and body parts, primarily for use in traditional medicine and for decoration; live animals were on sale to be kept as pets and wild meat for food. There were not observed any wildlife parts in Myawaddy on the border of Thailand. In Tachilek , a total of 35 species were recorded, of which 33 species are afforded some degree of protection under Myanmar’s national wildlife legislation and/or are listed in the CITES Appendices or in IUCN globally threatened categories. Only 18 of the 35 species observed were not listed in the CITES Appendices. Eight of the 35 species were not legally protected in the MWPL. According to interviews with local traders and from direct observations, most of wildlife species were brought by middle men from everywhere of Myanmar, furthermore, wildlife from Tachileik is traded not only to Thailand by using illegal route avoid the Myanmar -Thailand check point but also to China through Mong La , the border town as the destination of traded wildlife species. Therefore, wildlife parts were seen for sale in Tachileik apart from Myawaddy, where trade is locally prohibited.

Voltage Recovery Control Of Grid-Connected Wind Turbines At An External Short-Circuit Fault

The documented investigation in this paper examines main power quality issues of grid-connected wind turbines and the interaction between wind turbines and the grid. The main goal is to investigate the most popular type of grid-connected wind turbines with doubly fed induction generators (DFIG) during continuous operation, as well as the voltage recovery of gridconnected wind turbines after the clearance of a short circuit fault in the grid. Most models introduced above have some complexity and details. They spotted only on the normal operation of single wind turbines, without consideration of grid interaction faults. In these models either slip control alone or pitch control alone have been used leading to some voltage recovery or stability problems. This paper firstly introduces the configuration of main portions of grid-connected wind turbines which plays a very important role in the operation of wind power plants. Secondly, it proposes a new compact modeling of grid-connected wind turbines, which is free of any complex or details. This new model includes a combined control technique in which the dynamic slip control and pitch control are used together in such a way that the dip voltage after the clearance of faults is successfully rebuild and the grid-connected wind turbines maintain their stability efficiently. A simulation model of MW-level wind turbine is developed in the simulation tool program called power system computer aiding design (PSCAD). The simulation results show how the combination of dynamic slip control and pitch control could help the voltage to be rebuild and the power system stability be maintained efficiently. Keywords— wind turbines; wound rotor; doubly feed induction generator; dynamic slip; pitch.
