Adamson University is a private and Catholic university in Manila, Philippines, founded on June 20, 1932 by Greek immigrant George Lucas Adamson as the Adamson School of Industrial Chemistry. On February 5, 1941, the school was granted university status by the Department of Education, and on December 4, 1964, the university was turned over to the Vincentian Fathers of the Congregation of the Mission and was incorporated into the Adamson-Ozanam Education Institutions, Inc. Adamson University is also a Member of the University Athletics Association of the Philippines . Its patron saint is Saint Vincent de Paul.Adamson University has programs in Graduate School, Law, the Liberal Arts, science, Engineering, Nursing, Pharmacy, Architecture, Business Administration, Education, as well as secondary, elementary, and preparatory education. Adamson University has eight courses listed as Centers of Development and Centers of Excellence by the Commission on Higher Education and has been granted Autonomous status.Adamson University has been included in the top 201+ universities in Asia through Quacquarelli Symonds Asia University Rankings 2011. This makes Adamson University as top 9 in the rankings nationwide and top 5 in the Metro Manila area. Wikipedia.

A Web-based pile load test (WBPLT) system was developed and implemented in this study. Object-oriented and concept-based software design techniques were adopted to integrate the pile load test database into the system. A total of 673 case histories of pile load test were included in the database. The data consisted of drilled shaft and driven precast concrete pile axial load tests in drained, undrained, and gravel loading conditions as well as pre-analyzed data and back-calculated design parameters. Unified modeling language, a standard software design tool, was utilized to design the WBPLT system architecture with five major concept-based components. These components provide the static structure and dynamic behavior of system message flows in a visualized manner. The open-source Apache Web server is the building block of the WBPLT system, and PHP Web programming language implements the operation of the WBPLT components, particularly the automatic translation of user query into structured query language. A simple search and inexpensive query can be implemented through the Internet browser. The pile load test database is helpful, and data can be easily retrieved and utilized worldwide for research and advanced applications. © 2014 Techno-Press, Ltd. Source

An analysis model for predicting the tip bearing capacity of drilled shafts in cohesionless soils is improved in this study. The evaluation is based on large amounts of drilled shaft load test data. Assessment on the analysis model reveals a greater variation in two coefficients, namely, the overburden bearing capacity factor (Nq) and the bearing capacity modifier for soil rigidity (ζqr). These factors are modified from the back analysis of drilled shaft load test results. Different effective shaft depths and interpreted capacities at various loading stages (i.e., low, middle, and high) are adopted for the back calculation. Results show that the modified bearing capacity coefficients maintain their basic relationship with soil effective friction angle (φ), in which the Nq increases and ζqr decreases as φ increases. The suggested effective shaft depth is limited to 15B (B = shaft diameter) for the evaluation of effective overburden pressure. Specific design recommendations for the tip bearing capacity analysis of drilled shafts in cohesionless soils are given for engineering practice. © 2013 Techno-Press, Ltd. Source

This paper examines an analysis model for predicting the tip capacity of drilled shaft foundations under gravelly soils. Forty one static compression load test data are utilized for this purpose. Comparison of predicted and measured results demonstrates that the prediction model greatly overestimates the tip capacity of drilled shafts. Further assessment on the model reveals a greater variation in three coefficients; the effective overburden pressure (q̄), the overburden bearing capacity factor (Nq); and the bearing capacity modifier for soil rigidity (ζqr). These factors are modified from the back-analysis of the drilled shaft load test results. Varying effective shaft depths are considered for the back-calculation to explore their effects on capacity behavior. Based on the analyses, the recommended effective shaft depth for the evaluation of effective overburden pressure is limited to 15B (B=shaft diameter). The Nq and ζqr are enhanced while maintaining their basic relationship with the soil effective friction angle, φ̄ in which the Nq increases and ζqr decreases as φ̄ increases. Specific design recommendations for the tip bearing capacity analysis of drilled shafts in gravelly soils are given for engineering practice. © (2013) Trans Tech Publications, Switzerland. Source

Representative interpretation criteria are examined in detail to evaluate the lateral response of drilled shaft foundations in gravels. A database of field lateral load tests is used for the analysis. The representative criteria are subdivided into absolute displacement, displacement as a function of shaft diameter, rotation limit, mathematical model, and graphical construction method. Comparison of these criteria shows that the initial elastic region ends at approximately 3-5 mm, 0.50 %B, and 0.08° rotation, which represent the serviceability limit state. The final region begins at about 25 mm, 2.5 %B, and 0.33° rotation, which represent the ultimate limit state. The graphical construction methods, QL and QS&W, are located within the transition region of the curve. Among these criteria, the displacement limits, QL, and QS&W methods demonstrate more reliable results. The typical load-displacement curves for lateral capacity in gravels are developed for engineering practical use. Further, recommendations for the use of these interpretation criteria are also given. © 2013 Springer Science+Business Media Dordrecht. Source

Recent phylogenetic studies in the Vanguerieae adopted a narrow circumscription for Canthium characterized by the presence of supraaxillary spines. For a continuing project in Philippine Rubiaceae, an important focus was to resolve the disposition of spineless Philippine Canthium. In a collecting trip to key forested sites in the Philippines, two endemic Canthium species were collected: C.monstrosum and C. wenzelii. The absence of spines hinted at a deviation from Canthium sensu stricto (s.s.) and thus raised questions on their generic affiliation. Phylogenetic analysis of the combined ITS-trnL-F data sets showed a well-supported clade of Vanguerieae (PP = 1.00; BS = 100 %). The two endemic Canthium species seemed to have close affinity with Keetia (PP = 0.79; BS = 69 %), within a supported clade (PP = 0.99; BS = 80 %) containing Afrocanthium. Although the C. monstrosum–C. wenzelii-Keetia clade showed low BS support, it appears that morphological attributes shared by these taxa support this relationship. However, the Philippine endemics are morphologically distinct from Keetia by having a shorter calyx limb than the calyx tube, strictly pentamerous corolla, style ± same length with the corolla tube, wider than long stylar knob, glabrous disc, ellipsoid fruit and several features of pyrene such as strictly woody, an angular ventral side, presence of a longitudinal slit within the crest and the absence of a defined lid. To maintain homogeneity, taxonomic stability and distinct geographical distributions we proposed a new Philippine endemic genus Kanapia. © 2016 Springer-Verlag Wien Source
