Previous analyses of the ultimate resistance and displacements of flexible piles under lateral loads in cohesioniess soils have been reevaluated by using simple correlations based on standard penetration tests. Reasonable agreement is found between observed and predicted behaviour, and the new estimates are similar to those from the previous more elaborate methods. Key words : cohesioniess soils, displacements, lateral loads, soil resistance, standard penetration tests.

Previous analyses of the ultimate resistance and displacements of rigid piles under lateral loads and moments have been extended to the general case of eccentric and inclined loads on flexible piles by using the concept of effective embedment depths of equivalent rigid piles. Recent research on the behaviour of large model tests on instrumented rigid and flexible piles under eccentric and inclined loads in sand, clay, and layered soil is summarized. Reasonable agreement is found between observed and predicted behaviour. The proposed method of analysis is also supported by comparison with the results of many field case records of single piles and large pile groups under lateral loads indifferent types of soils. Key words : bearing capacity, displacement, eccentric loads, inclined loads, layered soil, pile.

The results of full-displacement pressuremeter tests in beds of sand, clay, and layered soil have been used to estimate the lateral soil pressures, ultimate capacity, and displacements of instrumented rigid model piles under eccentric and inclined loads. Comparisons of these estimates with observations on the piles under horizontal load and pure moment have been made and reasonable agreement is found. The analyses are also compared with some field case records. Key words: bearing capacity, clay, displacements, horizontal load, lateral pressure, layered soil, model test, moment, pile, pressuremeter, sand.

Ultimate Resistance

Abstract The ultimate resistance against a rigid cylinder which is moved laterally in a cohesionless soil is a function of the geometry of the cylinder and the properties of the soil. An approximate method is developed for computing this resistance and is tested against results of laboratory experiments. Satisfactory agreement between the method and experiment was obtained. Not only was the ultimate resistance against the cylinder measured, but careful measurements were made of the shape of the rupture surfaces. These measurements should allow the development of a more rigorous computation procedure. Introduction A critical aspect in the design of offshore drilling platforms is assuring the stability of the platform during a hurricane. The large horizontal loads from waves and wind make a severe loading condition. Piles are generally employed as the foundation since they can be effective in resisting both horizontal and vertical loads. Spuds are sometimes used with a mat foundation, where the spuds are designed principally to resist horizontal loads and the mat designed principally to resist vertical loads. The research reported in this paper is related to one aspect of the problem of laterally loaded piles or spuds in sand. The complete solution to the problem of the laterally loaded pile in sand would require the prediction of soil resistance against the pile as a function of pile deflection; only the ultimate resistance against short piles is considered in this paper. A considerable amount of additional research will be necessary to obtain a complete solution to the problem of the laterally loaded pile in sand; however, the work reported here should be useful as a guide in the performance of some of the additional research. ULTIMATE LATERAL RESISTANCE AGAINST A LONG WALL IN SAND To aid in the understanding of the theory which is developed for a cylinder, the theory for earth pressure against a wall is reviewed. In Fig. 1(a), a long wall of height H is shown embedded in soil. Soil resistance will develop as the wall is deflected, and the soil resistance will increase with deflection until some limiting value is reached. In this discussion, and those following, it is assumed that all points on the wall deflect equal amounts. A possible shape of the real curve which relates soil resistance to deflection is shown by the dashed line in Fig. 1(b); however, as a means of simplifying the discussion, an idealized curve (shown by the unbroken lines) is drawn. If such a wall as this were furnishing the horizontal support for an offshore structure, the dashed curve in Fig. 1 would be the information needed in performing a foundation analysis, with the idealized curve possibly being an acceptable substitute.

Offshore Piles

This paper employs a modified nonlinear boundary element approach to analyze the response of offshore piles subjected to external soil movements arising from submarine slides. Theoretical solutions for a realistic hypothetical offshore pile computed by the approach are presented and discussed. The analysis is then used to analyze the behaviour of two full-scale offshore piles in submarine slide areas, and reasonable agreement is found between observed and theoretical behaviour. Key words: seafloor instability, submarine slides, offshore piles, theoretical solutions, field tests.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract (1%). These tumors express the CD 117 in 95% of cases. The stomach is the preferential localization (70%). Diagnosis is difficult and sometimes late. Progress of imaging has greatly improved the management and the prognosis. Computed tomography (CT) is the gold standard for diagnosis, staging, and treatment follow-up. The increasing recognition of GIST’s histopathology and the prolonged survival revealed some suggestive imaging aspects. Key words: gastro-intestinal stromal tumors; computed tomography; diagnosis

This article aims at describing the obseroance of wasiat wajibah (compulsory bequeathment) in the Islamic court of Banten, analyzing the provision of the substitute heir and adopted children in the Compilation of  Islamic Law (KHI). In addition, the ideal laws to manage the innheritance rules in Indonesia. This article is library research by using doctrinal approach and using case study and survey methods. The data was, then, analyzed by using analytical descriptive and analytical correlative methods. The result showed that the observance of wasiat wajibah in the Islamic court of  Banten employed by judges is by using the Mawali Hazairin’s Doctrine. The criteria of the adoption of substitute heir and adopted children in the KHI is the attempts of Ulama and many judgees junst in giving legal justice and certainty to the society.   Key Words: Islamic Inheritance Law, Compilation of Islamic Law, Islamic court of  Banten

Five phosphorus rates (0, 5, 10, 20 and 30 kg P/ha) were tested with four rice genotypes in Boro (BRRI dhan36, BRRI dhan45, EH1 and EH2) and T. Aman (BRRI dhan30, BRRI dhan49, EH1 and EH2) season. Phosphorus rates did not influence grain yield irrespective of varieties in T. Aman season while in Boro season P response was observed among the P rates. Application of P @ 10 kg/ha significantly increased the grain yield. But when P was applied @ 20 and 30 kg P/ha, the grain yield difference was not significant. The optimum and economic rate of P for T. Aman was 20 kg P/ha but in Boro rice the optimum and economic doses of P were 22 and 30 kg/ha, respectively. Hybrid entries (EH1 and EH2) used P more efficiently than inbred varieties. A negative P balance was observed up to 10 kg P/ha.
