Human activities, primarily the burning of fossil fuels and changes in land cover and use, increases the atmospheric concentrations of greenhouse gases. This alters energy balances and tends to warm the atmosphere which will result in climate change. Being one of the very sensitive parameters, climate change can cause significant impacts on water resources by resulting changes in the hydrological cycle, and the spatial and temporal water resource availability can be significantly affected, which clearly amplifies its impact on sectors like agriculture, industry and urban development. The current study was conducted to indicate the look ahead flood probability and its impact on proposed dams, human life and infrastructure. Kunar basin is fed by melting glaciers and snow of the Hindu Kush mountains, which, together with snow and glacier melt, produce intense floods. The study analyses flood probability in Kunar river basin on proposed dams for a contemporary period (1984-2014) and three future periods (2015-2044, 2045-2074 and 2075-2099) using the RCP4.5 and RCP8.5 scenarios based on five bias-corrected downscaled climate models (ACCESS 1.3, INM-CM4, IPSL-CM5A, BCC-CSM 1.1 and HadGEM2-ES). After comparison the correlation coefficient between observed data and data of five different models, ACCESS 1.3 model had better relation then others so, this model is used. Contemporary period and future floods are modelled with the Soil Water Assessment Tool (SWAT) hydrological model was used in the study. This hydrologic model provides a link between climate changes and water yields through simulation of hydrologic processes within watersheds. Different components of water resource are simulated and crop yield, water quality are considered ate the Hydrological Response Unit (HRU). The simulation of river basin by SWAT hydrological model suggest that the average flow of flood for retrospective period is 4195.52 m3/sec, but according to RCP4.5 and RCP8.5 the average flow of flood for look ahead period is 7315.86 m3/sec and 6894.80 m3/sec. So, the results suggest an increasing trend due to an increasing precipitation and higher temperatures accelerates snow and glacier-melt. Kunar basin is the highest flow contributor in Kabul river basin, the basin has great untapped hydropower potential which could be harnessed for cheap hydro electricity generation, that is why government of Afghanistan proposed for several hydropower dams on this basin. This study can assist water managers and policy makers to indicate the location of critical areas in their preparation to accurate plan, manage the flood impact on dams and mitigate the effect of flood related damages in low land area of Kunar basin.

Objective: Meat quality characteristics and sensory attributes were evaluated in three age groups (12, 18, and 24 mo) of one-humped camels of the Saudi Arabian Najdi breed. Methods: Thirty-six male camels (12 for each age group) were used. The Longissimus dorsi muscle from each carcass was divided into three parts and subjected to three ageing periods (1, 5, or 10 d) and evaluated for shear force, myofibril fragmentation index (MFI), expressed juice, cooking loss, and sensory attributes. Results: Age had a significant effect on shear force, MFI, expressed juice quantity, and organoleptic properties. Camels slaughtered at 12 mo exhibited lower shear force and MFI, and higher expressed juice quantity, tenderness, juiciness, and overall acceptability than those slaughtered at 24 mo. Ageing had a significant influence on shear force, MFI, expressed juice quantity, but not on cooking loss. Camel meat aged for 10 d exhibited significantly lower shear force values and expressed juice quantity, and significantly higher MFI compared to that aged for 1 d. However, ageing did not significantly affect sensory attributes, except for tenderness, in camels slaughtered at 18 mo. Conclusion: Both instrumental and sensory evaluations showed that young camel meat has desirable quality characteristics, with superior tenderness and juiciness.

Axial.Flexural Interaction in FRP-Wrapped RC Columns

Hanan Suliman Al-Nimry,Rabi Amer Al-Rabadi 한국콘크리트학회 2019 International Journal of Concrete Structures and M Vol.13 No.7

The study reported herein aims at investigating the behavior of medium-scale circular reinforced concrete columns wrapped with fiber reinforced polymer (FRP) sheets under concentric and eccentric axial loads. The experimental program was devised to assess the effects of loading conditions, absence/presence of an FRP jacket as well as the FRP wrapping system. To achieve the study objectives, four column groups were tested under axial compression at 0, 25, 50 and 65 mm loading eccentricities corresponding to eccentricity-to-diameter ratios of 0, 0.13, 0.26 and 0.34, respectively. Specimens in a fifth group were tested in pure bending simulating axial compression at infinite loading eccentricities. Three column subcategories were tested under each of the 5 loading eccentricities: unwrapped; wrapped with one ply of hoop FRP sheets; and wrapped with two FRP plies with fibers oriented at 0 and 90° to the longitudinal column axis thereby providing externally-bonded longitudinal reinforcement and hoop confinement, respectively. Tests confirmed that FRP confinement enhances the axial–flexural column resistance even at large eccentricities that exceed the balanced state of unconfined columns. Although axial column resistance decreased with increasing bending moments, relative enhancements (25–35%) in axial resistance provided by FRP confinement were found to be more significant under eccentric loading than in pure compression. Compared to hoop FRP-confined columns, using additional longitudinal sheets resulted in minor (7–9%) but stable enhancements in axial resistance that were unaffected by the increase in loading eccentricity. The FRP hoop wraps had a minor effect on the flexural resistance of specimens tested in pure bending but managed to double their resistance when combined with the externallybonded longitudinal FRP sheets. Finally, three stress–strain models of FRP-confined concrete were used in conventional section analysis to assess the axial–flexural interaction in the FRP-jacketed columns. Strength predictions made using the stress–strain model proposed in ACI 440.2R-17 design guidelines did not agree with the test results of the eccentrically-loaded columns and underestimated the moment resistance at a given axial force even when considering higher confinement ratios than those permitted by the guidelines. Strength predictions made using eccentricitydependent stress–strain models showed better results especially when accounting for the increase in ultimate axial strains under eccentric loading.

Robotic-Assisted Device in Posterior Spinal Fusion for a High Risk Thoraculombar Fracture in Ankylosing Spondylitis

Ali Suliman,Ronit Wollstein,Benjamin Bernfeld,Alexander Bruskin 대한척추외과학회 2014 Asian Spine Journal Vol.8 No.1

Fractures in ankylosing spondylitis (AS) are often difficult to treat and surgical treatment may be fraught with complications. We describe the use of a robotic-assisted device in the surgical treatment of an unstable L1 fracture in an elderly patient with chronic lymphocytic leukemia and AS. The postoperative course was uneventful and the patient was discharged after 3 days. The use of a robotic-assisted device in spine surgery is particularly indicated in difficult high risk cases.

FRP Confinement of Heat-Damaged Circular RC Columns

Hanan Suliman Al-Nimry,Aseel Mohammad Ghanem 한국콘크리트학회 2017 International Journal of Concrete Structures and M Vol.11 No.1

To investigate the effectiveness of using fiber reinforced polymer (FRP) sheets in confining heat-damaged columns, 15 circular RC column specimens were tested under axial compression. The effects of heating duration, stiffness and thickness of the FRP wrapping sheets were examined. Two specimen groups, six each, were subjected to elevated temperatures of 500 『C for 2 and 3 h, respectively. Eight of the heat-damaged specimens were wrapped with unidirectional carbon and glass FRP sheets. Test results confirmed that elevated temperatures adversely affect the axial load resistance and stiffness of the columns while increasing their ductility and toughness. Full wrapping with FRP sheets increased the axial load capacity and toughness of the damaged columns. A single layer of the carbon sheets managed to restore the original axial resistance of the columns heated for 2 h yet, two layers were needed to restore the axial resistance of columns heated for 3 h. Glass FRP sheets were found to be less effective; using two layers of glass sheets managed to restore the axial load carrying capacity of columns heated for 2 h only. Confining the heatdamaged columns with FRP circumferential wraps failed in recovering the original axial stiffness of the columns. Test results confirmed that FRP-confining models adopted by international design guidelines should address the increased confinement efficiency in heat-damaged circular RC columns.

The tool provides three views that present the overall different and useful aspects for collaborations. Project managers can get a comprehensive understanding about collaborations between developers as well as contributions of each developer and how they are involved in the development process. The main components are menu bar, three graphical views and the timeline. First view presents the communication evolution. Second view presents system’s evolution and third view presents the modification history.

Drone-as-a-Service (DaaS) for COVID-19 self-testing kits delivery in smart healthcare setups: A technological perspective

Hafiz Suliman Munawar,Junaid Akram,Sara Imran Khan,Fahim Ullah,Bong Jun Choi 한국통신학회 2023 ICT Express Vol.9 No.4

Drones have gained increasing attention in the healthcare industry for mobility and accessibility to remote areas. This perspective-based study proposes a drone-based sample collection system whereby COVID-19 self-testing kits are delivered to and collected from potential patients. This is achieved using the drone as a service (DaaS). A mobile application is also proposed to depict drone navigation and destination location to help ease the process. Through this app, the patient could contact the hospital and give details about their medical condition and the type of emergency. A hypothetical case study for Geelong, Australia, was carried out, and the drone path was optimized using the Artificial Bee Colony (ABC) algorithm. The proposed method aims to reduce person-to-person contact, aid the patient at their home, and deliver any medicine, including first aid kits, to support the patients until further assistance is provided. Artificial intelligence and machine learning-based algorithms coupled with drones will provide state-of-the-art healthcare systems technology.

Introducing Contemporary Blockchain Platforms

Alrumaih, Malak Suliman International Journal of Computer ScienceNetwork S 2021 International journal of computer science and netw Vol.21 No.4

Blockchain and its infrastructure technology have expanded rapidly in the last decade and are in high demand, but there is a lack of comprehensive studies on those platforms. Blockchain is a new technology based on the distributed digital ledger system. Decentralized trust is one of the key factors behind the blockchain-based system. Transparency of such a system is better than a conventional centralized ledger system. By using a blockchain-based transaction system, any business organization can harness key benefits like data integrity, confidentiality, and anonymity without involving any third party in control of the transactions. Since the blockchain is used in numerous applications and the horizon is expanding at an unprecedented pace. So, there is a need for an introducing and reviewing of blockchain platforms. In this paper, we have reported a review on existing contemporary blockchain platforms. In particular, From the existing studies, we have identified eighty blockchain platforms and the majority of them have a lack of technical details. To provide the researchers a comprehensive introducing on blockchain platforms to perform a broad guideline for future research and investment in the blockchain domain.
