Conformal mapping of unbounded multiply connected regions onto canonical slit regions

We present a boundary integral equation method for conformal mapping of unbounded multiply connected regions onto five types of canonical slit regions. For each canonical region, three linear boundary integral equations are constructed from a boundary relationship satisfied by an analytic function on an unboundedmultiply connected region. The integral equations are uniquely solvable. The kernels involved in these integral equations are the modified Neumann kernels and the adjoint generalized Neumann kernels

Penggunaan Bahan Pengisi (Filler) Serbuk Keramik, Ditinjau dari Parameter Marshall pada Lapis Aspal Beton (Laston)

Transportasi merupakan salah satu urat nadi dalam perkembangan kemajuan suatu daerah atau negara, salah satu prasarana transportasi darat yang sangat penting adalah jalan raya. Pada Kenyataannya masih banyak jalan-jalan yang kurang memenuhi syarat, sehingga banyak jalan rusak dikarenakan kurang mampu untuk menahan beban lalu lintas jalan dan menerima beban kendaraan yang berlebihan, oleh karena itu diperlukan alternatif campuran-beraspal yang dapat diterapkan agar mampu mengatasi kerusakan-kerusakan akibat melemahnya daya ikat aspal terhadap butiran agregat dan filler, baik karena suhu, cuaca, mutu aspal dan agregat, maupun metode pelaksanaan dilapangan. Salah satu cara untuk mengatasi hal tersebut adalah dengan menggunakan bahan filler alternatif yaitu dengan menggunakan serbuk keramik. Tujuan penelitian ini adalah: (1) Mengetahui sifat dan karakteristik aspal tanpa menggunakan serbuk keramik; (2) Mengetahui penggunaan serbuk keramik sebagai filler dengan kadar 0%, 20%, 40%, 60%, 80%, 100%. (3) mengetahui Pada kadar prosentase berapakah nilai optimum penggunaan serbuk keramik sebagai filler terhadap karakteristik parameter marshall pada campuran aspal beton. Dalam penelitian ini metode penelitian dibagi menjadi tiga tahapan yaitu tahapan pemilihan bahan, tahapan persiapan dan pembuatan benda uji, serta tahapan penelitian dan analisis data. Hasil dari penelitian menyebutkan bahwa: (1) Nilai Stabilitas, Flow, VIM, dan Marshall Quotient tanpa penambahan serbuk keramik sebagai filler akan terus meningkat sampai titik maksimum kemudian turun kesuatu nilai seiring penambahan serbuk keramik sebagai filler, (2) Dengan bertambahnya kadar serbuk keramik maka nilai Stabilitas dan nilai Marshall Quotient campuran aspal akan semakin tinggi. Dari uji statistik menunjukan bahwa ada perbedaan nilai stabilitas dan nilai Marshall Quotient pada Lapisan Aspal Beton yang signifikan pada kadar serbuk keramik 60%, 80%, 100%; Selain itu nilai flow, VIM, dan VMA mengalami peningkatan dan pada kadar optimum mengalami penururan seiring penambahan filler serbuk keramik. (3) semua nilai dari karakteristik parameter Marshall masuk dalam spesifikasi yang disyaratkan. Namun jika dilihat dari pengujian hipotesis menggunakan Software SPSS 16.0 for Windows ada dua nilai parameter Marshall yang memiliki perbedaan yang signifikan yaitu pada nilai stabilitas dan nilai Marshall Quotient yang memiliki nilai signifikansi 0,00 pada kadar prosentase 60%, 80%, dan 100%

Polyfluorene as a model system for space-charge-limited conduction

Ethyl-hexyl substituted polyfluorene (PF) with its high level of molecular disorder can be described very well by one-carrier space-charge-limited conduction for a discrete set of trap levels with energy $\sim$ 0.5 eV above the valence band edge. Sweeping the bias above the trap-filling limit in the as-is polymer generates a new set of exponential traps, which is clearly seen in the density of states calculations. The trapped charges in the new set of traps have very long lifetimes and can be detrapped by photoexcitation. Thermal cycling the PF film to a crystalline phase prevents creation of additional traps at higher voltages.Comment: 13 pages, 4 figures. Physical Review B (accepted, 2007

Green construction in India: gaining a deeper understanding

A workshop on green construction was organized in New Delhi in July 2008 by Jamia Millia University, India and University of Salford, U.K., aiming to increase 'green' practices that are environmentally friendly and energy efficient. The workshop included participants from regulatory bodies, public and private construction companies and researchers. The object of the workshop was to provide an opportunity to capture issues, challenges and research issues in green practices throughout the supply chain in the construction sector in India. The methodology constituted a survey that was provided to all participants, where eight questions were composed by the facilitators. The participants were asked about their views on voluntary and compulsory ways of assessment and audit of green implementation in India. The findings of the workshop featured major challenges, drivers, initiatives, and the ways of effective implementation as well as enforcement on the discussed topic

Hyperforin: A lead for antidepressants

Depression is a complex but treatable disorder if diagnosed appropriately. However, despite the advances in the understanding of the molecular basis of this disorder and the vast range of medication, psychotherapy and electroconvulsive therapy, very safe and effective drug to treat this disease is still being sought. Several studies suggest that St.John’s wort (Hypericum perforatum L.) has phloroglucinol derivative, hyperforin, exhibiting antidepressant activity. This bioactive component can be exploited to create a major shift in the safer treatment of depression. Keywords: Hypericum perforatum L., St. John's wort, Antidepressant, Hyperfori

Parametric Modelling for Designing Offsite Construction

Increasing population and progressing economies around the world are generating huge demand for built assets. When this demand is dealt with conventional ‘sticks-and-bricks’ approach, it leads to usual delays, wastages, cost overruns, and quality issues, etc. Consequently, the traditional approach results in negative impacts on economic and social scenarios apart from being just unable to deliver required supply level of built assets. On the other hand, offsite construction techniques, when utilized appropriately, can significantly speed up the construction process and improve the quality of deliverables in addition to bringing in improved sustainability and better worker health and safety. But offsite practices are marred with a general perspective of its being cause of rigidity in the design processes and disproportional increment in coordination requirements. To address this perceived problem, the application of Building Information Modelling (BIM) has been conceptualized for the design of a prototype in this research. Simpler ways of modularization and effective optimization of design through parametric modelling has been developed. The methodology coming out of this design exercise, which is of reporting values of parametric variables real-time, is promising in the sense of ensuring the general and flexible usage of offsite practices. Further as experienced during the BIM modelling exercise for the prototype, the design iterations can be accomplished in a more informed manner and optimization run in an automated fashion by using the Application Programming Interface (API) of BIM authoring tool by taking advantage of already defined key parameters. This paper addresses these important issues at the conceptual level and determines a roadmap for further research
