Cigarette filters as additives for thermal-resistant composite fiberboard
No full textIn Partial Fulfillmentof the Requirements for the Degree Bachelor of Science in Civil EngineeringCigarette filters have always seemed to have been a problem worldwide because of their improper disposal due to the large amount of hazardoussolid waste produced. Incorporating these cigarette filters into thefabrication of composite fiberboard could be a radical solution for wastemanagement. Furthermore, this study mainly intends to develop athermal-resistant composite fiberboard using cigarette filters. Thethermal conductivity of the fabricated fiberboard, the density, waterabsorption, compressive and tensile strength were observed to assess itsefficacy. The different design mixtures of cigarette filters and sawdust inthe production of composite fiberboard were utilized in this study. Basedon the density results, the mean density of the design mixture 90:10 wascalculated to be lower than the mean density of the control samples. Itindicates that the amount of cigarette filters affects the density of thecomposite fiberboard. The density and water absorption results weresignificant, implying that the design ratio 90:10 has low density. Theresults indicate that the control samples are more compacted and canabsorb less moisture because of the absence of cigarette filter fibers. Onthe other hand, the fiberboards' compressive and tensile strengthproperty varies depending on the number of cigarette filters in thedesign ratio. Moreover, all the composite fiberboards containingdifferent proportions of cigarette filters improve their resistance tothermal compared to the sawdust only as it reduced by 18% for 80:20,14% for 85:15, and 12% for 90:10. Therefore, the inclusion of cigarettefilters have a desirable thermal insulation capability. The different testsconducted on the fiberboards showed that the best result obtained wasthe design mixture 85:15 among all the others. This is because it meets the standard requirements for commercial use. Conclusively, cigarette filters have the potential as an additive for commercially available fiberboards

Theobroma cacao seed oil as corrosion inhibitor for steel saline and acidic environment
No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Civil EngineeringCorrosion is a significant cause of structural failure because it deteriorates steel and
damages its physical and mechanical characteristics. Saline water and acid exposure of
steel metals contribute to faster corrosion activity affecting the integrity of steel on various
structural components, and the application of corrosion inhibitors may extend steel's
serviceability. This study investigated the corrosion inhibition properties of Theobroma
cacao seed oil on steel. The weight-loss method was used to determine the corrosion rate
and inhibition efficiency in steel submerged in saline and acid solutions as corrosion baths
with varying concentrations of Theobroma seed oil extract. The results indicate that in 1M
of H2SO4, the maximum efficiency rate of the medium was 70.75%, with an inhibitor
concentration of 0.8 mg/L. On the other hand, 98.72% inhibition efficiency was
demonstrated in artificial saline water at an inhibitor concentration of 0.2 mg/L. These
results demonstrate that the presence of T. cacao seed oil on steel slows corrosion at all
concentrations through the absorption of amino acids that form a protective layer

An integration of biophilic architecture to improve the thermal comfort and productivity of workers among commercial buildings in Mintal, Davao City/
No full textThis research aims to determine the significant difference in commercial buildings in terms of
thermal comfort and perceived productivity and the effects of thermal comfort on employees'
perceived productivity. A theoretical framework is adopted to explain how thermal comfort
influences employees' perceived productivity in each commercial building. It is an explored
concept in the defined context and has been developed by the researcher. Thermal comfort was
measured using the Guanxi Key Laboratory of New Energy and the Building Energy Saving
Guilin University of Technology questionnaire. For perceived productivity, the researcher used
a modified survey questionnaire from the study of Castelle (2017). The two instruments are
modified survey questionnaires to gauge the respondents' perception of their thermal comfort
and productivity. In analyzing the data, the researcher used Descriptive Statistics and Analysis
of variance (ANOVA) to know if thermal comfort and its effect on workers' productivity differ
in the selected three establishments. And the results showed a statistically significant difference
between the commercial buildings in terms of thermal comfort and perceived productivity.
Also, the analyzed data showed that thermal comfort affects the employees' perceived
productivity. This research supports the existing literature on thermal comfort and perceived
productivity. Furthermore, the researcher recommends that designers consider thermal comfort
and its effect on employees' perceived productivity.
