    The creation of intangible assets such as intellectual capital and Islamic ethics are crucial to cope with firm competitiveness issues. Five components of intellectual capital (human capital, organizational capital, relational capital, spiritual capital and technological capital) and Islamic work ethics were identified to model their impact on SME business performance in Malaysia. In doing so, survey questions from previous studies were adopted and customized to collect data. The sample of 445 SME entrepreneurs was utilized and the data were analyzed using SmartPLS 3.2.6. The results of the study revealed that human capital, organizational capital, technological capital and Islamic work ethics significantly influenced business performance. Then, this study explored the use of the Importance-Performance matrix analysis to identify priority factors that can be enhanced to increase business performance.Keywords: Importance-Performance Matrix Analysis (IPMA); SME; intellectual capital; Islamic work ethic

    Background: Anaesthetists frequently tailor the subarachnoid local anaesthetic dosage according to parturient height to achieve sensory blockade up to the T4 dermatome for lower segment Caesarean sections (LSCSs). Studies that have been conducted have demonstrated that height does not affect the spread of subarachnoid hyperbaric bupivacaine. This study aimed to find the correlation between the spinal column length of termparturients and the highest level of sensory blockade after spinal anaesthesia.Methods: The authors studied 60 singleton term parturients of American Society of Anesthesiologists (ASA) physical status I or II scheduled for elective LSCSs. The length of the spinal column was taken as an averageof three measurements from the C7 spinous process to the sacral hiatus in a sitting upright and facing forward position. Spinal anaesthesia was given by administering 1.8 ml of 0.5% hyperbaric bupivacaine and 25 μg fentanyl through the L3/L4 or L4/L5 intervertebral space. The level of sensory blockade was assessed using pin-prick testing for pain sensation. Linear regression analysis was used to analyse the correlation; R < 0.25 indicates no correlation with the level of significance being < 0.05.Results: The spinal column lengths measured were between 42.2 cm and 85.8 cm (median: 58.5 cm). Spinal anaesthesia given was adequate for all patients, with the highest levels of anaesthesia ranging from T8 to T2 with sensory levels between T6 and T4. The parturients’ spinal column length showed no correlation with the highest level of sensory blockade achieved, namely R = 0.11.Conclusions: The study found no correlation between the parturients’ spinal column length and the highest level of sensory blockade achieved.Keywords: spinal anaesthesia; spinal column; hyperbaric bupivacaine; parturients; lower segment Caesarean section (LSCS

    Modelling of a three-shaft high-bypass-ratio engine performance and emission prediction using hydrogen fuels

    The price of oil has seen an unprecedented increase and the resulting demand for oil, especially from the transportation industries. The pollution emits from the vehicle has affected human health and environmental problems especially aviation industries because the emission covers much broader spectrums. Drop-in alternative fuels such as liquefied hydrogen fuel are believed to offer better engine performance and reduce the emission. An in-house computer tool, PYTHIA was used to model the performance of RB211 engine at a wide range of flight operations. Liquid hydrogen fuel will increase the thrust and the specific fuel consumption up to 63.9% reduction at higher speed. Liquid hydrogen fuel resulted in higher burning temperature which encourage the formation of NOx. At the sea level, it was found that EINOx was increased to about 5.5% when 20% blended ratio was used

    Influence of Material Properties on the Fluid-Structure Interaction aspects during Molded Underfill Process

    This paper presents the investigation of the effects of epoxy moulding compound’ (EMC) viscosity on the FSI aspects during moulded underfill process (MUF). Finite volume (FV) code and finite element (FE) code were connected online through the Mesh-based Parallel Code Coupling Interface (MpCCI) method for fluid and structural analysis. The EMC flow behaviour was modelled by Castro-Macosko model, which was written in C language and incorporated into the FV analysis. Real-time predictions on the flow front, chip deformation and stress concentration were solved by FV- and FE-solver. Increase in EMC viscosity raises the deformation and stress imposed on IC and solder bump, which may induce unintended features on the IC structure. The current simulation is expected to provide the better understandings and clear visualization of FSI in the moulded underfill process

    Synthesis, crystal structure and Hirshfeld surface analysis of ethyl 4-hydroxy-2-(4-hydroxyphenyl)-1-methyl-5-oxo-2,5-dihydro- 1H-pyrrole-3-carboxylate

    Ethyl 4 hydroxy-2-(4-hydroxyphenyl)-1-methyl-5-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate, C14H15NO5 (1) was synthesized via multicomponent reaction (MCR) of sodium diethyl oxalacetate, methylamine, and 4-hydroxybenzaldehyde. The structure of 1 was elucidated by using FT-IR, NMR and GCMS. These results were further confirmed by means of single crystal X-ray crystallography. The results showed that 1 was crystallized in orthorhombic space group Pca21 where a = 17.102(4), b = 9.923(2), c = 16.037(4), Å. The quantification of intermolecular interactions in the crystal structure was obtained by Hirshfeld surface analysis and showed that the H•••H contacts were the most dominant interactions

    This is the Pre-print version of the Article. The official published version of the Paper can be accessed from the link below - Copyright @ 2010 IOPThe CMS silicon tracker, consisting of 1440 silicon pixel and 15 148 silicon strip detector modules, has been aligned using more than three million cosmic ray charged particles, with additional information from optical surveys. The positions of the modules were determined with respect to cosmic ray trajectories to an average precision of 3–4 microns RMS in the barrel and 3–14 microns RMS in the endcap in the most sensitive coordinate. The results have been validated by several studies, including laser beam cross-checks, track fit self-consistency, track residuals in overlapping module regions, and track parameter resolution, and are compared with predictions obtained from simulation. Correlated systematic effects have been investigated. The track parameter resolutions obtained with this alignment are close to the design performance.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)
