The Density And Index Of Preponderance Of The Giant Clam (Tridacna Maxima) In The Water Pasumpahan Island, Padang City, West Sumetera. The research has been done about the density and index of preponderance of the giant clam Tridacna maxima in the water Pasumpahan Island from June to October in 2003. The giant clam T. maxima colletion sites in the water Pasumpahan Island were divided three strata i, e. strata I ( at west Pasumapahan Island still have coral reef with seagrass), strata II (at north Pasumapahan Island which the coral reef was dominated by macro algae), strata III (at east Pasumpahan Island with mangrove ecosystem). At each strata the giant clam T. maxima were collected hree T. maxima. The giant clam was taken its stomach and then the stomach of giant clam were analysed. Results of the research showed that the composition of the natural food giant clam were phytoplankton and zooplankton. Based on the samples colletion mat the highest density from natural food of giant clam T. maxima were found at strata III 1813.54 plankton/ shell individu and the lowest density of natural food of giant clam T, maxima were 1256.52 plankton/shell individu at strata II. The highest density of natural food of giant clam T. maxima based on class were Bacillariophyceae and then Crustacea and the lowest density were Rotifera. The highest index of preponderance was found from Bacillariophyceae (30.47) and the lowest were Rotifera (0.93). Food preponderance index was calculed to indicate that the phytoplankton of Bacillariophyceae (30.47) and Crustacea (27.41) were the most preference food by T. maxima."

"A discussion of developments in the field of bifurcation theory, with emphasis on symmetry breaking and its interrelationship with singularity theory. The notions of universal solutions, symmetry breaking, and unfolding of singularities are discussed in detail. The book not only reviews recent mathematical developments but also provides a stimulus for further research in the field."

"This book provides a study aid on the finite element method. Based on the free computer algebra system Maxima, it presents routines to symbolically or numerically solve problems in the context of plane truss and frame structures. This allows readers to not only check classical hand calculations but also understand the computer implementation of the method. The mechanical theories focus on the classical one-dimensional structural elements, i.e. bars, Euler-Bernoulli and Timoshenko beams as well as their combination to generalized beam elements. Focusing on one-dimensional elements reduces the complexity of the mathematical framework and the resulting matrix equations can still be displayed with all components, and not only in a symbolic representation. The use of a computer algebra system and the incorporated functions, e.g. for equation solving, highlights the methodology of the finite element method rather than standard procedures."

"ABSTRAKPenelitian ini merupakan analisis sintaktis yang dilakukan pada bahasa Belanda Ratu Máxima Zorreguieta Cerruti yang terlahir sebagai warga negara Argentina dengan bahasa Spanyol sebagai bahasa ibu. Masalah yang diangkat dalam penelitian ini adalah bagaimana konstruksi sintaktis basantara ragam lisan yang dituturkan oleh Ratu Máxima dari sudut pandang psikolinguistik. Dalam penelitian diidentifikasi konstruksi klausa yang dituturkan oleh Ratu Máxima dalam tiga video wawancara dengan menggunakan Teori Keterprosesan yangdiajukan oleh Manfred Pienemann (1998) lalu menempatkannya ke dalam Skala Implikasional sehingga kemampuan berbahasa Belanda Ratu Máxima dapat diprediksi. Hasil penelitian menunjukkan bahwa dari keenam konstruksi dalam Teori Keterprosesan, hanya Konstruksi V-akhir yang masih menunjukkan angka kurang dari 70%. Hal ini menunjukkan bahwa bahasa Belanda yang digunakan oleh Ratu Máxima masih bersifat basantara. Selain itu, Ratu Máxima sudah menggunakan bahasa Belanda dalam konstruksi kompleks (Pisah, Inv, V-akhir) dan tidak lagi berpatokan hanya pada konstruksi simpleks (Satu Kata, Kanonis, Adv).

ABSTRACTThe research is syntax analysis on the speech act of Queen Máxima Zorreguieta Cerruti who was born as an Argentinian and speak Spanish as her first language. The problem which is brought in this research is how the syntactical construction of the Dutch language of Queen Máxima from psycholinguistics perspective. This research identifies the construction of clauses of Queen Máxima as appeared in three interview videos using the Processability Theory which is proposed by Manfred Pienemann (1998), and then place it into ImplicationalScale to estimate the level of Dutch ability of Queen Máxima. The result shows that from six constructions in the Processability Theory, only the V-end Construction which shows the percentage less than 70%. It shows that the Dutch level of Queen Máxima is still in the process of interlanguage. Other than that, she has started to use not only simple constructions (One Word, Canonic, Adv), but also more complex constructions (Separable, Inv, V-end)."

"This book is intended as an essential study aid for the finite element method. Based on the free computer algebra system Maxima, the authors offer routines for symbolically or numerically solving problems in the context of plane truss and frame structures, allowing readers to check classical ‘hand calculations’ on the one hand and to understand the computer implementation of the method on the other. The mechanical theories focus on the classical one-dimensional structural elements, i.e. bars, Euler–Bernoulli and Timoshenko beams, and their combination to generalized beam elements. Focusing on one-dimensional elements reduces the complexity of the mathematical framework, and the resulting matrix equations can be displayed with all components and not merely in the form of a symbolic representation. In addition, the use of a computer algebra system and the incorporated functions, e.g. for equation solving, allows readers to focus more on the methodology of the finite element method and not on standard procedures.

"Penentuan struktur patahan dalam eksplorasi sangat penting karena struktur patahan berasosiasi dengan permeabilitas tinggi yang umumnya adalah reservoar. Dalam penelitian ini dilakukan studi komparasi penetuan struktur patahan menggunakan metode FHD dan HVDM yang diaplikasikan pada model sintetik gravitasi dan data riil gravitasi. Identifikasi struktur patahan pada FHD dan HVDM ditunjukkan dengan nilai maksimum, dimana FHD didapatkan dari akar penjumlahan kuadrat turunan pertama arah horizontal X dan turunan pertama arah horizontal Y sedangkan HVDM didapatkan dari akar penjumlahan kuadrat horizontal, vertical dan diagonal coefficient dari proses DWT 2 dimensi. Berdasarkan hasil model sintetik gravitasi, FHD lebih baik menentukan struktur patahan dibandingkan dengan HVDM sedangkan untuk data riil gravitasi respon FHD dan HVDM memiliki respon yang hampir sama. Pada data riil gravitasi, tidak dapat ditentukan metode mana yang lebih baik dalam menetukan struktur patahan karena tidak adanya data geofisik lain sebagai data pendukung dalam menggambarkan struktur bawah permukaan di daerah penelitian "Y".

Fault structure determination during exploration is crucial since it associates with high permeability that, in general, called reservoir. Through this research, comparative study of fault structure determination using FHD and HVDM methods which are applied toward gravity synthetic model and gravity real data has been conducted. Identification of fault structure on FHD and HVDM are shown by maximum value, which FHD resulted from root sum square of horizontal X first derivative and horizontal Y first derivative meanwhile HVDM is obtained by horizontal, vertical and diagonal coefficient root sum square of 2-Dimensional DWT. Based on the result of gravity synthetic model, FHD could determine fault structure in a better way than HVDM whereas on gravity real data FHD and HVDM have a slightly similar response. On gravity real data, the better way to determine fault structure could not be concluded because there is no another geophysics data provided as supporting data to portray subsurface structure at research area "Y"."
