Finite element technologies have been applied to fluid dynamrcs problems for some time now. The early work focused on Galerkin 's method and various attempts to improve its stability while retaining its basic character. In the late 1970s a new approach was introduced, namely, "stabili zed methods," such as SUPG and Galerkin/least-s quares. These methods have been applied to many areas in fluid ...

A short-timescale sampling of phytoplankton abundance and diversity was carried out at Redang Island waters, South China Sea. Physico-chemical variables measured at four intervals over a day were relatively stable (temperature = 29 ± 0.6°C ; salinity = 27 ± 2 ppt, pH = 7.8 ± 0.1; total alkalinity = 2025 ± 33 μeq l–1) whereas inorganic nutrient concentrations (NH4 = 1.36 ± 0.51 μM; NO2 = 0.06 ± ...

The effect of photoinhib i t ion on the pr imary ( O a ) and secondary ( O b ) quinone acceptors of photosystem I I was investigated in isolated spinach thylakoids by the methods of thermoluminescence and delayed luminescence. The amplitudes of the Q (at about 2 °C) and B (at about 30 °C) thermoluminescence bands which are associated w i th the recombination of the S ;OA and S2QB charge pairs, ...

We examine the competitiveness of Hungarian agriculture in relation to that of the EU, based on four indices of revealed comparative advantage, for the period 1992 to 1998. Consistency tests suggest that the indices are less satisfactory as cardinal and ordinal measures, but are useful in identifying whether or not Hungary has a comparative advantage in a particular product group. Despite signi...

Neurochirurgische Operationen sind vielfach technisch komplex und aufwändig. Der Neurochirurg kann möglicherweise die Vielzahl an Informationen nicht optimal ausnutzen, Frustration und suboptimale Nutzung der Assistenzsysteme sind die Folge. Anhand der Resektion von Hirntumoren wurde die Aussagekraft von Workflowanalysen klinisch geprüft. Ein Editor wurde programmiert und 60 Patienten intraoper...

Pelaku usaha kopi luwak yang berada di Kabupaten Lampung Barat sudah memiliki kompetensi seharusnya dimiliki. Namun besaran tidak sama rata, terdapat dominan dan pula dominan. Besaran berbeda-beda, menimbulkan adanya perbedaan pada keadaan usaha. sedikit menunjukkan berkembang, sedangkan pelaku banyak lebih stabil. Kondisi terjadi saat ini memungkinkan munculnya wirausaha baru. Hal disebabkan d...

ABSTRAKPerubahan laju aliran air pada pembangkit listrik pikohidro dapat menyebabkan daya dan tegangan yang dihasilkan generator menjadi tidak stabil. Penelitian ini bertujuan untuk merancang Maximum Power Point Tracking (MPPT) dengan algoritma logika fuzzy Permanent Magnet Synchronous Generator (PMSG) penstabil aplikasi pikohidro. Pada penelitian digunakan dua unit konverter DC/DC tipe buck-bo...

The structural unit of the title compound, [Rb(C(6)H(3)N(2)O(4))(C(6)H(4)N(2)O(4))(H(2)O)(2)](n), consists of one rubidium cation, one hydrogen pyrazine-2,3-dicarboxyl-ate anion, one pyrazine-2,3-dicarboxylic acid mol-ecule and two water mol-ecules. This formulation is repeated twice in the asymmetric unit as the rubidium cation lies on an inversion centre. Each anion or acid mol-ecule is linke...

OBJECTIVE In spite of accumulating information about pathological aspects of sulfur mustard (SM), the precise mechanism responsible for its effects is not well understood. Circulating microRNAs (miRNAs) are promising biomarkers for disease diagnosis and prognosis. Accurate normalization using appropriate reference genes, is a critical step in miRNA expression studies. In this study, we aimed to...
