    Full text link
    The article offers a fresh perspective to analyze the conflict through observation of media coverage, proposing that through this close observation, the form, factors and motives of conflict can be easily identified. Through its observation, this paper records that the clash between Ahmadiyyah and other religious groups has predominated social conflict in Indonesia since 2005 until 2011. It argues that the conflict persistence is due to a weak law enforcement. The state is deemed to be failed to protect the minority group against the violent acts of other religious groups and it is this failure that this artcile associates with the escalation and development of the conflict

    Previous investigations have shown that a 3-mm-high carbon nanotube (CNT) forest has an acoustic absorption coefficient of about 5-10% within the frequency range 125 Hz-4 kHz, which is above that of conventional acoustic materials on a per-mass basis. It was hypothesised that a CNT array of greater height, lower density, and with a non-uniform arrangement of the nanotubes could enhance the amount of acoustic absorption. In order to investigate this hypothesis, an impedance tube test was conducted to measure the acoustic absorption coefficient of a relatively tall 6-mm CNT forest. The results indicate that a greater length and lower density of CNTs may improve the absorption performance of CNT-based acoustic absorbers. Analyses of the results showed anomalies in the measured acoustic absorption coefficient compared with previous investigations. Theoretical analyses were performed based on classical models of acoustic absorption to explain the anomalies. This study describes the factors that may affect the acoustic absorption behaviour of nanomaterials.M. Ayub, A. C. Zander, C. Q. Howard, B. S. Cazzolato, D. M. Huang, N. T. Alvarez, and V. N. Shano

    A real-world exploration into clinical outcomes of direct oral anticoagulant therapy in people with chronic kidney disease: a large hospital-based study

    Background There is limited evidence to support definite clinical outcomes of direct oral anticoagulant (DOAC) therapy in chronic kidney disease (CKD). By identifying the important variables associated with clinical outcomes following DOAC administration in patients in different stages of CKD, this study aims to assess this evidence gap. Methods An anonymised dataset comprising 97,413 patients receiving DOAC therapy in a tertiary health setting was systematically extracted from the multidimensional electronic health records and prepared for analysis. Machine learning classifiers were applied to the prepared dataset to select the important features which informed covariate selection in multivariate logistic regression analysis. Results For both CKD and non-CKD DOAC users, features such as length of stay, treatment days, and age were ranked highest for relevance to adverse outcomes like death and stroke. Patients with Stage 3a CKD had significantly higher odds of ischaemic stroke (OR 2.45, 95% Cl: 2.10–2.86; p = 0.001) and lower odds of all-cause mortality (OR 0.87, 95% Cl: 0.79–0.95; p = 0.001) on apixaban therapy. In patients with CKD (Stage 5) receiving apixaban, the odds of death were significantly lowered (OR 0.28, 95% Cl: 0.14–0.58; p = 0.001), while the effect on ischaemic stroke was insignificant. Conclusions A positive effect of DOAC therapy was observed in advanced CKD. Key factors influencing clinical outcomes following DOAC administration in patients in different stages of CKD were identified. These are crucial for designing more advanced studies to explore safer and more effective DOAC therapy for the population

    Forage yield of berseem (Trifolium alaxandrium) as affected by phosphorus and potassium fertilization

    This research was conducted with the aim to quantify the effect of phosphorus and potassium fertilization on forage yield of berseem (Trifolium alaxandrium). The experiment was carried out at the Research Farm of Khyber Pakhtunkhwa, Agricultural University Peshawar, Pakistan during the cropping season of 2004 to 2005. Randomized complete block design (RCBD) having four replications was used for the experiment. Significant differences were found among the treatments for number of branches per plant, fresh forage yield and dry forage yield. The highest number of branches per plant (9.15), fresh forage yield (6077 kg ha-1) and dry forage yield (156.83 kg ha-1) were recorded in plots with 60 kg P ha-1 x 30 kg K ha-1 treatments, while the lowest values of 6.93, 5430 kg ha-1 and 153.80 kg ha-1 for branches per plant, fresh forage yield and dry forage yield, respectively were recorded in the plots with no fertilizer (control). Emergence (m-2) and plant height of berseem were non-significantly affected by phosphorus and potassium fertilization. So, it was concluded that berseem showed better performance in terms of higher forage yield under 60 kg P ha-1 x 30 kg K ha-1 levels in Peshawar valley.Key words: Phosphorus, potassium, forage yield, berseem

    Variability of 137Cs and 40K soil-to-fruit transfer factor in tropical lemon trees during the fruit development period

    In this investigation we evaluate the soil uptake of 137Cs and 40K by tropical plants and their consequent translocation to fruits, by calculating the soil-to-fruit transfer factors defined as Fv = [concentration of radionuclide in fruit (Bq kg-1 dry mass)/concentration of radionuclide in soil (Bq kg-1 dry mass in upper 20 cm)]. In order to obtain Fv values, the accumulation of these radionuclides in fruits of lemon trees (Citrus limon B.) during the fruit growth was measured. A mathematical model was calibrated from the experimental data allowing simulating the incorporation process of these radionuclides by fruits. Although the fruit incorporates a lot more potassium than cesium, both radionuclides present similar absorption patterns during the entire growth period. Fv ranged from 0.54 to 1.02 for 40K and from 0.02 to 0.06 for 137Cs. Maximum Fv values are reached at the initial time of fruit growth and decrease as the fruit develops, being lowest at the maturation period. As a result of applying the model a decreasing exponential function is derived for Fv as time increases. The agreement between the theoretical approach and the experimental values is satisfactory.Fil: Velasco, Ricardo Hugo. Consejo Nacional de Investigaciones Científicas y Técnicas.

    Molecular dynamics simulations of sound wave propagation in a gas and thermo-acoustic effects on a carbon nanotube

    Get PDF
    Published: 19 January 2016Molecular dynamics (MD) simulations have been performed to study sound wave propagation in a simple monatomic gas (argon) and the thermo-acoustic effects on a single walled carbon nanotube (CNT). The objective of this study was to understand the acoustic behavior of CNTs in the presence of acoustic waves propagating in gaseous media. A plane sound wave was generated within a rectangular domain by oscillating a solid wall comprising Lennard-Jones (LJ) atoms with the same intermolecular potential as the gas molecules. A CNT was aligned parallel to the direction of the flow at the wall at the opposite end of the domain. Interatomic interactions in the CNT were modeled using the REBO potential. The behavior of the sound wave propagation in argon gas without the CNT was validated by comparison with a previous study. The simulation results show that the thermo-acoustic behavior of CNTs can be simulated accurately using MD and that large-scale MD can be performed in the ultrasonic frequency range. This investigation will contribute to an improved understanding of the acoustic absorption mechanism of these nanoscopic fibers.Md Ayub, Anthony C. Zander, Carl Q. Howard, David M. Huang, Benjamin S.

    Heat losses are a major limiting factor for the efficiency of internal combustion engines. Furthermore, heat transfer phenomena cause thermally induced mechanical stresses compromising the reliability of engine components. The ability to predict heat transfer in engines plays an important role in engine development. Today, predictions are increasingly being done with numerical simulations at an ever earlier stage of engine development. These methods must be based on the understanding of the principles of heat transfer.In the present work  V type multi cylinder engine assembly is modeled by CATIA V5.
