Rice Husk Ash (RHA) and Sugarcane Bagasse Ash (SCBA) as partial replacement of cement for concrete hollow block (CHB)

Much research had established the use of major crops as an additive and/or replacement in the construction. This study utilized and determined the optimum amount of rice husk ash (RHA) and sugarcane bagasse ash (SCBA) as partial replacements of cement in a 1:4 ratio of cement to the sand mixture in developing concrete hollow blocks (CHB) by testing its compressive strength, water absorption, and fineness of cement mixture. Five set-ups were identified in this paper in terms of percentage replacement on the amount (0%, 2.5%, 5%, 7.5%, and 10%). The result showed an increase in fineness residue from 0%-10% cement mixture. The compressive strength test results showed an increase in compressive strength of 0-10%, with a significant drop at 7.5%. On the other hand, the water absorption test displayed an increase in moisture content from 0% to 10% replacement. 86.67% have met the DPWH and ASTM strength requirements, and all cement mixtures are below 10%, not exceeding the minimum requirement. Further analyses of the results were discussed as well. In conclusion, 5% each of RHA and SCBA was used as the optimum replacement to cement in terms of compressive strength for non-load-bearing CHBs.

Two stage planetary gear system configured as auxiliary power drive for robots

This research paper address a novel auxiliary power drive design problem with planetary gear system. The proposed configuration can produce dynamic obstacle avoidance and robot safe evacuation during power failure. The proposed system uses two stage planetary gear systems. First stage acts as a speed reduction phase connected to constant power source such as engine. Since dynamic controls and system output are applied to the second stage, system dependency at first stage is reduced. In this proposed configuration, the second stage can be used to alter the output of first stage by increasing or decreasing speed. Further in case of first stage power failure for any reason, the second stage alone can produce the necessary output to evacuate the robot safely. This article covers the basic mechanical design.

A Suitability Analysis of Vertical Garden System: Cases in the City of San Fernando, Pampanga, Philippines

Urban heat island refers to the phenomenon in which urbanized areas experience significantly higher temperatures compared to surrounding rural or natural landscapes. Vertical gardens and other greenery methods have emerged as potential solutions to mitigate the effects of urban heat islands and create sustainable cities that foster a livable and secure quality of life. This research study explores the suitability of implementing vertical garden systems in existing structures in the City of San Fernando, Pampanga, Philippines. The main objective is to create a checklist that can be used as a tool to assess and determine the appropriate design for the selected structures. Two vertical garden designs were provided: The Attached System and Free-Standing System, and these designed systems were modified depending on each case. A structured survey was also conducted among the participants, who are a residential structure owner, a commercial structure owner, and an institutional structure owner, to know the possible reason for adapting the system. The findings of this study provide valuable insights into the feasibility of vertical garden systems, which can significantly influence the extent to which these systems are embraced and integrated into existing structures.

Project aslag: an assessment of material application between photoluminescent line marking and traditional line marking at Santa Rita and Porac mega dike in Pampanga

Car accidents happen around the world, it does no matter if it is a third-world or first-world country. Stopping accidents from happening is impossible, but prevention and lessening the chances of road accidents are the next ideal step. Hence, this study in Sta. Rita and Porac Mega dike was conducted to assess the effectiveness of photoluminescent line markings to lessen the accidents in the area due to this area having virtually few streetlights, having an elevated road that is several feet above, and being a common route for cars, trucks, and motorcycles. Raosoft was used to determine the minimum recommended population. With a total population size of 20,000, a margin of error of 10%, and a 90% confidence level, the minimum recommended sample size is 68. The major instrument that has been used in this study was a survey questionnaire. The questionnaire was validated by a research expert, a statistician, and an engineer. This study proved the effectiveness of photoluminescent line marking and is also helpful in reducing accidents along the Sta. Rita and Porac Mega dike. Likewise, it can be used as a guide for the motorist. It can also be easily seen because it is glow-in-the-dark paint. Further, findings about the durability of the photoluminescent line marking indicated that it is reliable in terms of quality and longevity.

Statistical Analysis of Per Capita GDP and Infant Mortality Rate – An Indian Perspective

This study examines the most basic question: To what degree does economic expansion, as shown by GDP growth, result in a decline in mortality? Over the last few decades, many public health programs in developing nations like India have placed a strong emphasis on the health outcomes of children. Macroeconomic growth is frequently regarded as a crucial policy tool for enhancing health in India with its low per capita GDP. The assumption is that economic growth will raise average incomes for people, especially for the poor, and that this will improve life quality by allowing for better-quality consumption of goods and access to health care services as well as better housing and sanitation. However, does this also result in a decrease in infant mortality?

Evaluation of the Performance and Skills of the Civil Engineering Students Batch 2023 and Civil Engineering Instructors of Don Honorio Ventura State University with the Transition of Different Learning Setups

The government decided to temporarily close all educational institutions due to the COVID-19 pandemic for the protection of students, teachers, and the school community. This paper intended to evaluate the performance and skills of the Civil Engineering Students Batch 2023 of Don Honorio Ventura State University and Civil Engineering Instructors who experienced the transition of education to different learning setups. A descriptive-quantitative study design has been utilized wherein analyzing data, statistical treatments such as weighted mean, standard deviation, and analysis of variance, were used in order to identify the particular problems. Survey questionnaires were used in this study where 251 4th-year Civil Engineering Students and 14 Civil Engineering Instructors served as the respondents. The results revealed that the traditional learning setup was found to be the most effective platform for the students and instructors that suits their chosen program. While the students’ performance and skills during online learning varied in terms of adaptability and convenience. Blended Learning is the balance method between traditional and digital learning approaches. On the other hand, the level of agreement of the instructors in the Civil Engineering Department regarding the different educational setups also varied. They generally prevailed that face-to-face classes were the most efficient way to impart proficiency on certain topics and enhance students’ skills with regard to the civil engineering program. The results will serve as the foundation for developing an academic intervention program for Civil Engineering Students in order to adapt to the academic transition Keywords: Transition, Different Learning Setups, Performance, and Skills
