An Investigation on Strength Development of Cement with Cenosphere and Silica Fume as Pozzolanic Replacement

In the detailed study presented in this paper, an attempt was made to study the strength of cement when cenosphere (CS) and silica fume (SF) were used as replacement. Tests were carried out on mix with cenosphere as replacement for cement which has 12% of constant replacement of silica fume to the mass of cement, and this is made to stabilize the strength which was lost due to addition of cenosphere. From the test results, it was concluded that the strength loss of binder due to replacement of cenosphere can be stabilized by silica fume and still a safe value of strength can be achieved. Furthermore, the strength reduction is due to the consumption of hydration products and cloggy microstructure as observed in this study

Adakitic Paracale Granodiorite in southeastern Luzon, Philippines: A peek at a Proto-Philippine Sea Plate-related magmatic arc

This paper describes the geochemistry, petrogenesis and tectonic setting of a silicic pluton, the Paracale Granodiorite (PG), intruded into an ophiolitic suite in southeastern Luzon island, Philippines. Whole rock chemistry suggests that the PG samples are calc-alkaline and are characterized by light rare earth element (LREE)-enrichment and relatively weak heavy rare earth element (HREE)-depletion. They also show depletion in Nb, Ta, Zr and Ti and positive anomalies in K, Pb and Sr when normalized with the Primordial Mantle and normal-mid-ocean ridge basalt (N-MORB). The PG biotite mineral chemistry shows an affinity to calc-alkaline trends based on the FeOtot versus Al2O3, whereas in the MgO-Al2O3 plot, they exhibit transitional calc-alkaline to peraluminous characteristics. These information, along with a temperature \u3e600 °C based on biotite chemistry, and hydrous setting for the generation of the PG suggest generation in a subduction-related setting. When plotted in the Y versus Sr/Y and YbN versus (La/Yb)N, the PG samples exhibit adakitic signature. Partial melting, fluid addition and sediment participation are discerned from the geochemistry. Melting, assimilation, storage and homogenization (MASH) with limited fractionation are the dominant mechanisms of formation. The PG could represent a Late Cretaceous to Paleogene magmatic arc generated during the subduction of the proto-Philippine Sea Plate

A systematic review of the literature on digital transformation: insights and implications for strategy and organizational change

In this article we provide a systematic review of the extensive yet diverse and fragmented literature on digital transformation (DT), with the goal of clarifying boundary conditions to investigate the phenomenon from the perspective of organizational change. On the basis of 279 articles, we provide a multi-dimensional framework synthesizing what is known about DT and discern two important thematical patterns: DT is moving firms to malleable organizational designs that enable continuous adaptation, and this move is embedded in and driven by digital business ecosystems. From these two patterns, we derive four perspectives on the phenomenon of DT: technology impact, compartmentalized adaptation, systemic shift and holistic co-evolution. Linking our findings and interpretations to existing work, we find that the nature of DT is only partially covered by conventional frameworks on organizational change. On the basis of this analysis, we derive a research agenda and provide managerial implications for strategy and organizational change.info:eu-repo/semantics/publishedVersio

Drilling constraints on lithospheric accretion and evolution at Atlantis Massif, Mid-Atlantic Ridge 30°N

Author Posting. © American Geophysical Union, 2011. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Journal of Geophysical Research 116 (2011): B07103, doi:10.1029/2010JB007931.Expeditions 304 and 305 of the Integrated Ocean Drilling Program cored and logged a 1.4 km section of the domal core of Atlantis Massif. Postdrilling research results summarized here constrain the structure and lithology of the Central Dome of this oceanic core complex. The dominantly gabbroic sequence recovered contrasts with predrilling predictions; application of the ground truth in subsequent geophysical processing has produced self-consistent models for the Central Dome. The presence of many thin interfingered petrologic units indicates that the intrusions forming the domal core were emplaced over a minimum of 100–220 kyr, and not as a single magma pulse. Isotopic and mineralogical alteration is intense in the upper 100 m but decreases in intensity with depth. Below 800 m, alteration is restricted to narrow zones surrounding faults, veins, igneous contacts, and to an interval of locally intense serpentinization in olivine-rich troctolite. Hydration of the lithosphere occurred over the complete range of temperature conditions from granulite to zeolite facies, but was predominantly in the amphibolite and greenschist range. Deformation of the sequence was remarkably localized, despite paleomagnetic indications that the dome has undergone at least 45° rotation, presumably during unroofing via detachment faulting. Both the deformation pattern and the lithology contrast with what is known from seafloor studies on the adjacent Southern Ridge of the massif. There, the detachment capping the domal core deformed a 100 m thick zone and serpentinized peridotite comprises ∼70% of recovered samples. We develop a working model of the evolution of Atlantis Massif over the past 2 Myr, outlining several stages that could explain the observed similarities and differences between the Central Dome and the Southern Ridge

Financial Literacy and Decision-Making Skills for an Improved Teacher’s Financial Well-Being and Professional Qualities

Amidst the COVID-19 pandemic, it is not only the schools, curriculum and the learners who have experienced the changes in the education. Teachers are also moving forward in order to adopt to the changes. Unfortunately, many teachers are experiencing financial stress because of proper financial management in both budget and loan. This study attempted to determine the impact of financial literacy and decision-making skills in improving the financial well-being and professional qualities of public school teachers. This study is a descriptive -correlational research through a survey conducted last April 2021. There were 177 teacher-respondents from fifteen schools in Candelaria East District, Division of Quezon who are mostly above 31-40 years old, females, married, bachelor’s degree holders, Teacher I, with a salary of P15,000 – P 24,000 and rendered 1-10 years in service. Results showed that teachers’ financial literacy and the decision-making skills are proven to be practiced. Furthermore, financial well-being and professional qualities were also being practiced. The study recommends that the teachers should be careful in managing their finances and keep themselves aware about the proper ways of spending their money and the importance of savings and investments. They should also remember that despite all the stress that they are experiencing, they should keep in doing their best in their profession

Relations of Financial Literacy and Decision-Making Skills to Teacher’s Financial Well-Being and Professional Qualities

This study determined the relations of financial literacy and decision-making skills in the financial well-being and professional qualities of select public school teachers. The study used descriptive-correlational design through a survey data gathering strategy. There were 177 teacher-respondents from fifteen schools in Candelaria East District, Division of Quezon in the Philippines. The participants on the survey conducted on April 2021 were majority 31 to 40 years old, female, married, bachelor’s degree holder, teacher 1 employment status, with salary range of P15,000 to P 24,000 from their 1 to 10 years of service. The results of the self-assessment showed that the teachers’ financial literacy and the decision-making skills were proven to be practiced. Furthermore, the financial well-being and professional qualities were also being practiced. This study recommends on the continuous education of the teachers with regards to the financial literacy. On personal level, being cautious in engaging with loans and disengagement with debt-trap are basic but powerful practices
