    Background: Anatomy is one of the core sections of Basic Medical Sciences. Given the central role of anatomy, the development of medical knowledge and reach new horizons in science is not possible without relying on anatomy. Since in the anatomy science, students are familiar with the basic terms of medical language, the anatomy's hard to know and have a negative attitude towards this course. With these conditions, anatomy professors have an important role in providing incentives for medical students. However, sometimes applying tastes and the entry of too much anatomical detail creates conditions that cut the motivation for medical students. Therefore, this article seeks to offer solutions to cut apply tasteless and coordinate the teaching of anatomy to interest and motivate medical students to increase this lesson

    Assessment of the most adverse wind form-factor for single storey buildings

    Get PDF
    A major consideration in the design of single storey buildings is the wind load imposed on the walls and roof of the structure. This wind load is mainly (by definition) the result of the wind velocity at the area of the building under consideration.In Australia and New Zealand the Standard AS/NZS 1170.2:2011 is the main technical standard governing the assessment of wind loads on buildings, and hence a major influence on their design.In AS/NZS 1170.2:2011 (p.14) there is an implied assumption that the wind, on the scale of buildings, has a straight or uniform front, where the velocity is identical from one end of the building to the other. And that if the wind is hitting the building at an angle, that the passage of the impacting wind front will be linear. In other words, that any gusts will be of the same magnitude as they pass various parts of the building.Furthermore, on the same page (p.14), there is reference to a "3 second gust wind data", where the maximum wind velocity is maintained for 3 seconds on to the building.This thesis shows that: a) The wind does not impinge on to a building as a uniform, ruler-straight front, and b) The wind does not maintain a maximum velocity for 3 seconds at any part of a building.The thesis demonstrates that the wind has, at any interval of even a few seconds, a constantly fluctuating irregular front. Also, that the wind at a particular part of the building will vary in speed and direction from one fraction of a second to the next.The implication for building design is that the structure cannot experience the full wind load even in the most adverse conditions. That only a part of the structure can suffer the maximum wind speed at a time, and even then for less than one second at a time.Thus the total wind load that must be resisted by extended portions of a building issignificantly less than assumed by AS/NZS 1170.2:2011.The thesis proposes an equation that defines the "shape" of the wind front as a number which shall be called the "wind form factor". Although the behavior of air streams has been investigated in detail in respect of boundary layers and gradients varying with height, at levels of less than a metre, in micro seconds, and also at the very large scale of kilometres, and over hours, there is very little information as to the behavior of the wind at intermediate distances of a few metres and in time periods of seconds.It is hoped that this thesis will go some way towards addressing the lack of data

    In this paper, we analyze the performance of code acquisition system in atmospheric optical code division multiple access (OCDMA) communications using optical orthogonal codes. Memory introduced by temporal correlation of optical fading process precludes us from using the Markov chain model for a code acquisition analysis. By considering this issue, we discuss how to extend the applicability of the Markov chain model to the atmospheric OCDMA communications. We analyze and compare the performance of correlator and chip level detector (CLD) structures in the acquisition system. In our analysis, we consider the effects of free space optical channel impairments, multiple access interference, and receiver thermal noise in the context of semi-classical photon-counting approach. Furthermore, we evaluate the performance of various two stage schemes that utilize different combinations of active correlator, matched filter, and CLD in search and verification stages, and we find the optimum acquisition scheme among them. Numerical results show significant improvement in reducing the acquisition time and required power for synchronization using our optimum scheme in the wireless OCDMA communications

    ObjectiveHypoxia-ischemia-induced brain injury is a major cause of acute mortality and chronic neurological disability in infants and children.Imaging plays a vital role in diagnosing and treating hypoxicischemic encephalopathy (HIE) and as an adjunct to acute conditions and provides valuable information on long-term prognosis.Materials & MethodsOur study was prospective with 50 neonates aged 34 weeks and older with HIE. Cerebral ultrasound and MRI were performed on the infants, and the pattern of lesions was recorded. A pediatric neurologist examined the infants, and their developmental status was assessed and recorded with electroencephalography (EEG) findings.The data were analyzed. ResultsThe sonography pattern was normal in 26 (76.5%) term neonates, and also, the PVL pattern was observed in 10 term neonates. The incidence of observing an edema pattern (17.6%) was significantly different between the term and pre-term infants (P-value = 0.001).MRI findings were normal in 20 (58.8%) term neonates and 11 premature neonates. However, the PVL pattern was observed in MRI performed in six term neonates (6.6%). The watershed pattern (17%) showed that these differences were significant between the term and pre-term infants (P-value = 0/001). ConclusionNormal sonography was significantly higher in neonates with normal neurodevelopment than in patients with normal MRI and EEG findings but with poor neurodevelopment. Also, the probability of having normal MRI results was lower in neonates with moderate to severe asphyxia compared to ultrasound and EEG. &nbsp

    PRINSIP-PRINSIP HUKUM/HAK-HAK KELUARGA DALAM FIKIH JA’FARI & SISTEM SYAR’I REPUBULIK ISLAM IRAN

    Prinsip sentralitas keluarga dalam sistem hukum Iran dapat banyak membantu keseimbangan kepentingan dalam sistem hukumnya. Hal-hal yang berhubungan dengan ahwal syakhshiyyah, terutama pernikahan, dalam seluruh agama, memiliki relasi yang kuat dengan kayakinan keagamaan. Dari satu sisi, ketidakpedulian terhadap perubahan-perubahan sosial akan memunculkan undang-undang yang mati dan kaku dalam hubungan sosial. Dan dari sisi lain, mengabaikan nilai-nilai keagamaan dan terutama pada perilaku yang memiliki sensitifitas terhadap madzhab akan melahirkan dualitas dalam sistem-sistem yang mendominasi perilaku sosial. Ide sentralitas keluarga, dengan memanfaatkan hukum-hukum fikih dan memperhatikan al-ghayah asy-syar’iyyah dari hukum pernikahan dalam fikih Ja’fari melalui pembaharuannya, relatif dapat memberikan dominasi pandangan terhadap hak-hak keluarga di Iran dalam menghadapi perubahan-perubahan sosial dan mengarahkan kepada sistem tunggal dalam sistem keluarga di tengah masyarakat Iran sebagai negara religius. Prinsip-prinsip hasil istinbath dari referensi-referensi ijtihad menurut maktab fikih Ja’fari dalam bidang hukum/hak-hak keluarga dan dimasukkan dalam UUD Republik Islam Iran, melahirkan dominasi sistem hukum khusus terhadap keluarga. Pasal 10 UUD Republik Islam Iran menjadikan keluarga  sebagai yang terpenting dan pemersatu masyarakat. Maka seluruh undang-undang, aturan dan perencanaan  yang berhubungan dengan itu bertujuan memudahkan pembentukan keluarga dan menjaga kesucian dan kelanggengan hubungan kekeluargaan

    Resource allocation for fog computing based on software-defined networks

    Get PDF
    With the emergence of cloud computing as a processing backbone for internet of thing (IoT), fog computing has been proposed as a solution for delay-sensitive applications. According to fog computing, this is done by placing computing servers near IoT. IoT networks are inherently very dynamic, and their topology and resources may be changed drastically in a short period. So, using the traditional networking paradigm to build their communication backbone, may lower network performance and higher network configuration convergence latency. So, it seems to be more beneficial to employ a software-defined network paradigm to implement their communication network. In software-defined networking (SDN), separating the network’s control and data forwarding plane makes it possible to manage the network in a centralized way. Managing a network using a centralized controller can make it more flexible and agile in response to any possible network topology and state changes. This paper presents a software-defined fog platform to host real-time applications in IoT. The effectiveness of the mechanism has been evaluated by conducting a series of simulations. The results of the simulations show that the proposed mechanism is able to find near to optimal solutions in a very lower execution time compared to the brute force method

    In recent years, the number of end users connected to the internet of things (IoT) has increased, and we have witnessed the emergence of the cloud computing paradigm. These users utilize network resources to meet their quality of service (QoS) requirements, but traditional networks are not configured to backing maximum of scalability, real-time data transfer, and dynamism, resulting in numerous challenges. This research presents a new platform of IoT architecture that adds the benefits of two new technologies: software-defined networking and fog paradigm. Software-defined networking (SDN) refers to a centralized control layer of the network that enables sophisticated methods for traffic control and resource allocation. So, fog paradigm allows for data to be analyzed and managed at the edge of the network, making it suitable for tasks that require low and predictable delay. Thus, this research provides an in-depth view of the platform organize and performance of its base ingredients, as well as the potential uses of the suggested platform in various applications

    Value relevance of available-for-sale financial instruments (AFS) and revaluation surplus of PPE (REV) components of other comprehensive income

    Value relevance studies have thus far provided mixed evidence.Studies also found that fair value reporting has a significant impact on the value relevance of other comprehensive income. Additionally, most studies on value relevance of other comprehensive income focused on developed countries where the capital market is more efficient.In these settings due to the existence of active market, fair valuation of assets may not pose a major problem.In Malaysia the mandatory reporting of comprehensive income by all listed firms based on the requirement of FRS101, coincides with the adoption of FRS139 the standard for financial instrument and could be an interesting setting to investigate.This study hypothesized that other comprehensive income and its components are associated with share price.The results indicate that other comprehensive income and its components are value relevant.The results indicate that the move towards a more comprehensive income reporting through the preparation of the Statement of Comprehensive Income results in more informative financial reporting
