  • Durability of Lumber Pretreatment Compared to Posttreatment Processes

    • Authors: Solomon I Ubani*
      Abstract: Aim of study: In terms of treatment, it is essential to consider the correct use of preservatives and epoxy resin. Lumber pretreated with these substances can protect the wood from biodegradation or insect attack for exceeding three-year life expectation periods.Methods: To further increase durability and structural integrity, Posttreatment like painting or lamination on wood surfaces helps keep moisture out and carries a higher yield compared to traditional methods. In addition, chemical treatments to make timber resistant to fungal infestations as well has been gaining traction recently which makes it possible for lumber to be used in even more applications safely than ever before. Results: Thus, proper treatment plays a major role when considering the implications of using lumber as a resource both structurally and functionally over time. Conclusion: Lumber remains one of the most sought-after resources due to its versatility; likewise finding ways how impart maximum longevity necessitates research into new treatments available so that we can optimally exploit such abundant supplies without compromising the durable nature of good quality timber source.

  • Microbial Conversion and Utilization of CO2

    • Authors: Ge-Ge Wang; Yuan Zhang, Xiao-Yan Wang*, Gen-Lin Zhang
      Abstract: Rising greenhouse gas emissions have contributed to unprecedented levels of climate change, while microbial conversion and utilization of CO2 is a practical way to reduce emissions and promote green manufacturing. This article mainly summarizes several natural CO2 pathways that have been discovered, including the Calvin cycle, the reduced tricarboxylic acid (rTCA) cycle, the Wood–Ljungdahl (WL) pathway, the 3-hydroxypropionate/4-hydroxybutyrate (HP/HB) cycle, the dicarboxylate/4-hydroxybutyrate (DC/HB) cycle, the 3-hydroxypropionate (3HP) cycle, the reductive glycine (rGly) pathway, and artificially designed carbon fixation pathways includes the CETCH cycle, the MOG pathway, the acetyl-CoA bicycle, and the POAP cycle. We also discussed applications of different carbon fixation enzymes, notably ribulose-1, 5-diphosphate carboxylase/oxygenase, pyruvate carboxylase, carbonic anhydrase, as well as formate dehydrogenase. This paper further addressed the development of photosynthetic autotrophs, chemergic autotrophs and model bacteria Escherichia coli or yeast produced main products for CO2 fixation through metabolic engineering, such as alcohols, organic acids, fatty acids and lipids, bioplastics, terpenoids, hydrocarbons, and biomass.  Future studies on CO2 microbial conversion should focus on improving the efficiency of carbon fixation enzymes, metabolic modules of the carbon sequestration pathway, and intracellular energy utilization. Coupled microbial and electrochemical methods for CO2 fixation, in addition to biological fixation, show considerable promise.

  • Sea Level Rise Impacts in Coastal Areas and Possible Mitigation
           Engineering Approaches

    • Authors: Silvano Focardi; Milva Pepi*
      Abstract: Coastal areas are subjected to both natural and man-made actions, leading to a deterioration of coastal structures. Climate change has had a heavy impact on these areas in recent years. An important consequence of these actions is sea level rise. This phenomenon is the most important cause of coastal erosion, a serious problem with ecological, economic, and human health consequences. The countermeasures to contrast this phenomenon and the degradation of the entire coastal system, are represented by engineering interventions. These basically consist of approaches for adaptation to sea level rise, namely protection, retreat, and accommodation. Variations and site adaptation of these actions can involve procedures of no intervention; advancement; protection; retreat; accommodation; and ecosystem-based adaptation. While these procedures have provided coastal benefits and protection, in the long run, they may cause further coastal disruption and further aggravate the situation. Such interventions, therefore, require an accurate assessment of the advantages and disadvantages. However, it is certainly necessary to proceed with actions aimed at mitigating climate change, respecting the rules in a sustainable way.

  • Design and construction of solar-powered smart garbage disposal unit

    • Authors: Olowosebioba AA*; Folorunsho AD, Akindele BA, Akingbade FS, Andrew IO, Olaniyi GA
      Abstract: Cities with developing economies experience exhausted waste collection services, and inadequately managed and uncontrolled dumpsites; which is an ongoing challenge and many struggles due to weak institutions and rapid urbanization. The purpose of the research is to design and construct a smart garbage disposal system using a two-way power supply unit (that is, the electrical power supply unit and solar power supply unit) based on Arduino Nano that utilizes ATMEGA 328p microcontroller. Two pairs of ultrasonic sensors, the pair that faced upward detects the presence of garbage disposal agent at a close distance of (5 - 50) cm and then opens the lid while the other pair faced the inside of the container senses when the container is filled up and then closes the container until it is emptied are used.

  • Understanding RNG Gas Quality through Execution at Newtown Creek WRRF RNG

    • Authors: Pradheep Kileti*; Brian Barkwill, Devinder Mahajan
      Abstract: With each passing year a new record for global emissions is set (1) and policymakers and utility companies must embrace all avenues for decarbonization of energy. Universal adoption of electrification for every building and home by 2050 (2) is not practical, a balance must be struck between an equitable transition to cleaner energy supplies and ensuring uninterrupted, safe delivery of energy to utility customers. Renewable Natual Gas (RNG) is a molecule-for-molecule replacement of traditional geological natural gas with tangible life cycle emissions reductions. California continues to lead the way, initially starting with the low carbon fuel standard (LCFS) which aimed to reduce the carbon intensity of transportation fuel, and subsequently, Senate Bill 1440, which established RNG procurement goals including 12% RNG by 2030 (3). Other States are starting to adopt similar changes such as Oregon’s Senate Bill 98 and Colorado’s Senate Bill 21-264. As utilities attempt to transition the energy network, they must never compromise system safety and reliability. Recognizing that raw biogas has dangerous levels of contaminants of concern (COC) and must be conditioned to pipeline quality, its important utility companies better understand the methods with which methane is extracted and the testing protocols used to confirm performance. This paper highlights the equipment, processes, and testing regime National Grid and its partner the New York City Department of Environmental Protection (NYC DEP) deployed as part of its Newtown Creek RNG project, which successfully began injecting RNG into the NYC gas distribution network in October 2022.

  • Evaluation of factors affecting the quality of luxury residential
           buildings using the fuzzy BWM method

    • Authors: Marziyeh Sadat Moayeri; Seyed Azim Hosseini*, Mehdi Nani, Hamidreza Rabieifar, Jafar Asadpour
      Abstract: The construction sector consists of a collection of activities related to buildings and engineering constructions of all kinds. It is the close relationship between this sectors with other economic sectors, which distinguishes it. Therefore, it is an important indicator of the movement of the national economy, but this sector faces major risks, especially in the construction of luxury residential buildings, and these risks may affect the implementation of the project and may lead to increase costs, affect the quality and sometimes delay delivery. This study was carried out to evaluate the factors affecting the quality of luxury residential buildings in Iran using the fuzzy best-worst method (fuzzy BWM). The BWM method provides a consistent structural comparison of factors through best and worst criteria. And this method extended using a fuzzy set to address the ambiguity from the decision-maker’s judgment. The evaluation consists of five criteria: Strength and stability, physical comfort and mental peace, visual proportions and beauty, safety, security and environment, and welfare and health. To determine the fuzzy criteria’ weights, the nonlinearly constrained optimization problem was applied. The result indicated that the best and the worst criteria were Visual proportions and beauty and welfare and health.
