The Expansion Motor of Tarek Soukar Is a Real Global Warming Reducer
No full textGlobal warming matter is a word problem. Most solutions are preventative; they only avoid or reduce the heat emissions to the minimum. The natural solution for global warming matter is to increase vegetation. However, no industrial treatment to solve this problem has been invented yet. One great idea to solve this problem is to convert the extra heat to another shape of power. This method can really reduce global warming. Expansion Motor of Tarek Soukar represents this technical method .The expansion motor has not been addressed before, it is a new invention. It was supposed to be a solar engine, but it has proved that it is not limited to the Sun, but can be run by any other existing heat. All engines and motors are heat diffusers, while the expansion motor is a heat absorbent. As a result, with such a solution global warming is not a problem anymore, it became a new resource of power. Researchers and manufacturers are requested to start adopting, developing, producing this motor and spreading it widely
Character Values Education Through Tarek Pukat Dance for UNIKI Performing Arts Education Students
No full textThe purpose of this study was to determine the character value education in the Tarek Pukat dance of UNIKI Performing Arts education. This study uses a qualitative descriptive method, and a case study approach. Data collection techniques use the stages of observation, interviews and document analysis. With the aim of examining the character values contained in the Tarek Pukat Dance. A qualitative approach with a case study design was used to specifically understand character values in educational praxis through the Tarek Pukat Dance. The results of this study indicate that in the Tarek Pukat dance, the character value education that is seen is in the form of religious, responsibility, tolerance, discipline, cooperation values, humility and this is packaged into character value education in the Tarek Pukat Dance, namely religious values that are born in the Tarek Pukat Dance contain strong religious values, such as patience and perseverance, discipline, humility and responsibility. Social values in the Tarek Pukat Dance such as cooperation, mutual cooperation, humility and tolerance. Cultural values that can be taken from the Tarek Pukat Dance symbolize Acehnese cultural values, such as strength and resilience of local culture and love of the homeland. Aesthetic value: Tarek Pukat Dance also symbolizes aesthetic values, such as beauty and art from local culture. Tarek Pukat dancers in UNIKI performing arts education have and are able to implement the religious values of Tarek Pukat Dance used in religious ceremonies, social events, such as weddings and other events. Cultural events such as festivals have aesthetics, such as art performance
Diseño curatorial en la poética y política de la etnografía actual: una Conversación entre Tarek Elhaik y George E. Marcus
No full textEn este diálogo, George Marcus y Tarek Elhaik empiezan reexaminando los cambios en la práctica investigativa y los paradigmas iniciados hace más de veinte años por las deliberaciones de Writing Culture y continúan evaluando el devenir de esos debates en el pensamiento y la práctica antropológica contemporánea. Entre una figura clave del momento de Writing Culture y un antropólogo formado en el período que siguió a esas discusiones se produce un intercambio, una exploración y un refinamiento de afinidades conceptuales. La conversación genera un conjunto de conceptos estratégicos clave del repertorio modernista y cosmopolita, apreciado por ambos antropólogos (montaje, diseño, instalación), que influye en la figura emblemática del trabajo de campo. El llamado de Marcus a principios de los 90 por una etnografía como antídoto al realismo desesperanzador de películas y textos etnográficos y de los recientes “para-sitios” de performances en el Centro de Etnografía de la Universidad de California en Irvine se combina con la propuesta de Elhaik de la práctica curatorial como procedimiento, método y modo de producción teórica que abra la posibilidad para idear y componer un “libro-instalación”. La conversación propone tales figuras emergentes y nuevos experimentos como modos alternativos de mediación de la etnografía en proceso y, quizás, como sustitutos del trabajo de campo en sí mismo
Strontium isotopes in otoliths reveal a diversity of natal origins for Tarek (Alburnus tarichi) in Lake Van, Turkey
No full textUnderstanding the relative contributions of different spawning habitats to adult fish populations is central to effective fisheries management and species conservation. The Tarek (Alburnus tarichi) is an adfluvial cyprinid that is endemic to the alkaline-saline waters of Lake Van, Turkey. Tarek are culturally and economically important to the region, and also threatened by anthropogenic impacts, including poaching, dams, water diversions, pollution, and habitat degradation. Here we analyzed otoliths from 120 adult fish caught in Lake Van in 2016-2017 to reconstruct the age structure and natal origins of this Tarek population. Ages ranged from 2 to 10 years, with most fish belonging to the 2011-2014 cohorts (age 3-5). We analyzed strontium isotope ratios from water samples collected in 2016 and 2018 to build a baseline map and then used linear discriminant function analysis to classify Tarek to their likely natal origins. We found that adult Tarek originated from at least 7 different major tributaries of Lake Van, with a majority of fish originating from the Gevas and Engil tributaries in the south. Furthermore, the relative contributions of fish from each tributary varied among years, suggesting that a mosaic of natal habitats may be important for population stability. These results suggest that protection of all Lake Van watersheds from anthropogenic disturbance could be valuable for maintaining the stability of the Lake Van Tarek population and fishery
IoD swarms collision avoidance via improved particle swarm optimization
No full textDrones flights have been investigated widely. In the presence of high density and complex missions, collision avoidance among swarm of drones and with environment obstacles becomes a challenging task and indispensable. This paper aims to enhance the optimality and rapidity of three dimensional IoD path generation by improving the particle swarm optimization (PSO) algorithm. The improvements include using chaos map logic to initialize the population of PSO. Also, adaptive mutation is utilized to balance local and global search. Then, the inactive particles are replaced by new fresh particles to push the solution toward global optimal. Furthermore, Monte Carlo simulation is carried out and the results are compared with slandered PSO and with recent work CIPSO. The results exhibit significant improvement in convergence speed as well as optimal solution which prove the ability of proposed method to generate safety path for IoD formation without collision with terrain obstacle and among drones.The authors would like to acknowledge the support of the department of the computer engineering at King Fahd University of Petroleum and Minerals for this work.Ahmed, G (corresponding author), King Fahd Univ Petr & Minerals, Comp Engn Dept, Dhahran, Saudi Arabia.

UAV-enabled intelligent traffic policing and emergency response handling system for the smart city
No full textAs modern cities expand and develop, the resultant increase in population density gives rise to the need for smart solutions to cope with the demands applied to the infrastructure of the city. In this paper, we investigate the shortcomings of traffic policing and emergency response handling systems; propose an intelligent, autonomous UAV-enabled solution; and describe the system in a simulated environment. Several scenarios of traffic monitoring and policing system are considered in the simulation: traffic light violations and accident detection, mobile speeding traps and automated notification, congestion detection and traffic rerouting, flagged stolen vehicles/pending arrest warrants and vehicle tracking using UAVs, and autonomous emergency response handling systems. Furthermore, smart city infrastructure enable intelligent handling of emergencies by providing traffic light prioritization for ground emergency response units to reduce delay for patient care, automated physical bollard on routes with congested points due to accidents or hazards, first responder support UAV units-medical supplies UAV, fire fighting UAV to combat or control small fires, and numerous other benefits. Lastly, we present the results of the simulated system and discuss our findings.This study received financial support from the Special Research Fund (BOF) of Hasselt University, Belgium.

Conceptual affinities are exchanged, probed and refined between a key figure of theWriting Culture moment and an anthropologist trained in the aftermath of those discussions. The conversation brings a set of key strategic concepts from the cosmopolitan modernist repertoire dear to both anthropologists (montage, design, installation) to bear upon the emblematic figure of fieldwork. It foldsMarcus’ call in the early 90s for an ethnographics as an antidote to the hopeless realism of ethnographic films and texts and recent performative “para-sites” at his Center for Ethnography at UC Irvine with Elhaik’s deployment of curatorial practice as a procedure, method and mode of theoretical production that opens the possibility for thinking and composing an ‘installation book’. The conversation proposes these emerging figures and new experiments with form as alternate modes of mediation of
ethnography in process and, perhaps, as surrogates to fieldwork itself
Severe pediatric ocular injury due to explosion of a firecracker inside a soda bottle
No full textTarek A ShazlyDepartment of Ophthalmology, Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, MA, USAAbstract: This case report describes a penetrating ocular injury, followed by endophthalmitis, in a four-year-old girl, resulting from explosion of a small K0201 match-cracker inside a soda bottle. The patient presented with two corneal lacerations, ruptured crystalline lens, multiple intraocular foreign bodies, and hyphema of the right eye, for which immediate surgical exploration and repair was performed. The patient developed aggressive endophthalmitis that led to atrophy of the eye within a few weeks. Severe ocular injuries can result from small, relatively &ldquo;safe&rdquo; firecrackers. Therefore, this type of firework should not be used, especially by minors.Keywords: pediatric trauma, endophthalmitis, firecracke
