    The overall objective of this paper is to produce success criteria considered critical in international joint ventures (IJV), specifically between Malaysian and foreign contractors outside Malaysia. The recognition of such criteria will contribute to the identification of non-viable projects and will enable improvements to be made to the IJV and other similar economies. Data specific to the present study was collected through face-to-face interviews, which were carried out with the General Manager of the respective companies to provide detailed information on their company structure, management and experience of any joint venture projects undertaken outside Malaysia. The main findings from the interviews are that the critical factors in IJV partner selection criteria were related to the reputation, inter-partner trust, experience, personal knowledge of the partner organizations, commitment and human resources management. The employment of Malaysian sub-contractors also lessened the complexity of management. This is largely due to the familiarity of working with fellow Malaysians in the Middle East

    Nanoparticle shape and thermal radiation on Marangoni Water, Ethylene Glycol and Engine Oil Based Cu, Al2O3 and SWCNTs

    The aim of this paper is to investigate the relationship between particle shape and radiation effects on Marangoni boundary layer flow and heat transfer of water, ethylene glycol and engine oil based Cu, Al2O3 and SWCNTs. There are three types of nanoparticle shapes are considered in this research such as sphere, cylinder and lamina. The governing nonlinear partial differential equations are reduced into a set of nonlinear ordinary differential equations by applying similarity transformation which is solved using shooting technique in conjunction with Newton’s method and Runge Kutta algorithm. Temperature profiles are graphically and tabularly provided for the effects of solid volume fraction parameter, radiation parameter and empirical shape factor. The result shows that solid volume fraction and radiation energy gives a good impact on thermal boundary layer. Sphere nanoparticle shape predicts a better result on heat transfer rather than other nanoparticle shapes

    Fish powder as a low-cost component in media for producing bacterial cellulose

    Get PDF
    Some bacteria can produce extracellular bacterial cellulose (BC). This polysaccharide is chemically identical to cellulose produced by plants but has no associated lignin and hemicelluloses. The unique mechanical properties, chemical stability and purity allow BC to be exploited for a range of biomedical applications. However, medium costs limit commercial BC production. The suitability of using fish powder as a low-cost media component for producing BC by submerged culture of Gluconacetobacter xylinus in shake flasks was investigated. Fish powder was made by drying and grinding Koi carp (Cyprinus carpio), a pest fish in New Zealand waterways. Fermentations were done at 30oC in a growth medium containing 50 g/L glucose, the required minerals, and either 5 g/L yeast extract or 15 g/L fish powder, The BC yield on both yeast extract and fish powder was 0.04 g/g glucose, demonstrating fish powder was a suitable low cost ingredient for supplying nitrogen and amino acids in the media

    Monitoring Cairan Infus Berdasarkan Indikator Kondisi dan Laju Cairan Infus Menggunakan Jaringan Wifi

    Intisari – Sistem monitoring cairan infus sampai saat ini belum banyak ditemukan di rumah sakit ataupun institusi kesehatan lainnya tetapi sangat membantu perawat dalam melaksanakan tugas rutinnya dalam memantau kondisi cairan infuse.. Makalah ini membahas tentang perancangan system monitoring yang dapat memantau kondisi cairan infus secara realtime menggunakan pc maupun smartphone. System ini bekerja mengatur tetesan infuse permenit dan memberitahukan kondisi cairan infuse yang akan habis. Hasil pengujan didapatkan pengaturan tetesan infuse kurang tepat, terdapat selisih yang bervariasi di tiap pengujian sedangkan pengujian kondisi cairan infuse bekerja dengan tepat, ini dibuktikan dengan alarm pada pc dan smartphone selalu berbunyi pada saat cairan infuse akan habis

    The paper investigates and analyzes the effect of transformational leadership on employee creativity and role moderation of task support and relation support impact transformational leadership to employee creativity, The samples in this study were employees in the rubber research center of Bogor, West Java. As for the respondents in this study were employees under the supervisor position and can provide the required information in the study and be willing to be a respondent. Respondents of this study are 85 respondents. The sampling method used was Convenience sampling, Data analysis using hierarchical regression. Based on the analysis of the results obtained: 1) have the effect of transformational leadership be on the creativity of employees, 2) task support of a leader does not have an influence on the creativity of employees, 3) relation support of the leader has an influence on employee creativity; 4) task support of a leader does not moderate the effect of transformational leadership be on creativity employees; 5) relation support of the leader has moderate the effect of transformational leadership be on creativity employees. Penelitian ini menguji dan menganalisis pengaruh kepemimpinan transformasional pada kreativitas karyawan dan peran moderasi dari variabel penugasan pemimpin dan dukungan relasi pemimpin yang mempengaruhi variabel gaya kepemimpinan transformasional pada tingkat kreatifitas karyawan. Sampel dalam penelitian ini adalah karyawan di pusat penelitian karet Bogor, Jawa Barat. Adapun yang menjadi responden dalam penelitian ini adalah karyawan dengan jabatan di bawah supervisor dan dapat memberikan informasi yang dibutuhkan dalam penelitian ini serta bersedia untuk menjadi responden. Responden penelitian ini berjumlah 85 responden. Metode sampling yang digunakan adalah Convenience sampling, Analisis data menggunakan hierarchical regression. Berdasarkan analisis diperoleh hasil: 1) kepemipinan transformasional memilki pengaruh pada kreativitas karyawan; 2) dukungan penugasan pemimpin tidak memiliki pengaruh pada kreativitas karyawan; 3) dukungan relasi pemimpin memiliki pengaruh pada kreativitas karyawan; 4) dukungan penugasan pemimpin tidak memoderasi pengaruh kepemipinan transformasional pada kreativitas karyawan; 5) dukungan relasi pemimpin memoderasi pengaruh kepemipinan transformasional pada kreativitas karyawa

    Wind tunnel pressurization and recovery system

    Get PDF
    The high density, low toxicity characteristics of refrigerant-12 (dichlorofluoromethane) make it an ideal gas for wind tunnel testing. Present limitations on R-12 emissions, set to slow the rate of ozone deterioration, pose a difficult problem in recovery and handling of large quantities of R-12. This preliminary design is a possible solution to the problem of R-12 handling in wind tunnel testing. The design incorporates cold temperature condensation with secondary purification of the R-12/air mixture by adsorption. Also discussed is the use of Freon-22 as a suitable refrigerant for the 12 foot wind tunnel

    Quantum canonical transformations in Weyl-Wigner-Groenewold-Moyal formalism

    Get PDF
    A conjecture in quantum mechanics states that any quantum canonical transformation can decompose into a sequence of three basic canonical transformations; gauge, point and interchange of coordinates and momenta. It is shown that if one attempts to construct the three basic transformations in star-product form, while gauge and point transformations are immediate in star-exponential form, interchange has no correspondent, but it is possible in an ordinary exponential form. As an alternative approach, it is shown that all three basic transformations can be constructed in the ordinary exponential form and that in some cases this approach provides more useful tools than the star-exponential form in finding the generating function for given canonical transformation or vice versa. It is also shown that transforms of c-number phase space functions under linear-nonlinear canonical transformations and intertwining method can be treated within this argument.Comment: 15 pages, no figures.
