Use of the its Region in the Identification of Endophytic Mycota in Fruits of Syagrus Coronata (MART.) BECC., Caatinga Bioma
Authors: Da Silva Mabel Sherlla Rozendo Campos , Vitória Nadja Santos 
Published: January 2024

Objective: The study aimed to identify the endophytic fungi present in fruits of S. coronata (licuri) through sequencing of the ITS (Internal transcribed spacer) region.

Theoretical framework: The Syagrus coronata palm tree, known as licuri, plays a significant role in the Caatinga, both in socioeconomic and cultural terms. The fruits of this plant host several types of fungi, including saprophytes, phytopathogens, and endophytes. The complexity of fungi taxonomic identification, due to the diversity and morphological similarity between distinct taxa, often requires the use of molecular biology as an essential tool for accurate characterization.

Method: The study used 14 isolates of endophytic fungi from fruits of S. coronota (licuri) preserved in the Mycoteca of the Mycology Laboratory of the Universidade do Estado da Bahia/DEDC - Campus VIII, Paulo Afonso. The DNA of these isolates was extracted to perform PCR (Polymerase Chain Reaction) using the primers ITS1F and ITS4. The PCR products were sequenced and analyzed with the Blastn tool, revealing 98 to 100% similarity in the accessions.

Results and conclusion: From the 14 isolates, four presented themselves as Chlamydospores and one as Mycelia sterilia, making morphological identification unfeasible, and four were from taxa without taxonomic identification. The taxa identified using ITS region sequencing belong to the genera Curvularia, Diplodia, Fusarium, Lasiodiplodia, Neodeightonia, and Penicillium.

Research implications: This study highlights the importance of using molecular techniques to complement the taxonomy based on morphological markers.

Originality/value: The primary purpose of this study was to use the ITS region as a tool for identifying endophytic fungi in licuri fruits, since in the literature the mycota of this botanical substrate, which is a biocultural heritage of Bahia, is practically unknown.

Objective: Quantify and qualify the soil macrofauna present in areas cultivated with brassicas under the No-till system vegetable (NTSV) in different phases.

Method/design/approach: The study was conducted in three different areas: 1-NTSV with one year (NTSV1), 2-NTSV with three years (NTSV3), 3-Native Forest (In natural regeneration for 20 years (NF20)); At depths: 0-10; 10-20 and 20-30 cm, with 5 repetitions. Litter was collected in an area of 0.50x0.50 cm and soil samples were collected with an iron square measuring 25x25x30 cm in each plot, where the number of individuals (ind m-2) was quantified and the total richness and diversity and equitability indexes of the macrofauna were qualified.

Result and conclusion: The management in areas NTSV1, NTSV3 and NF20 favored the development of the population of the Formicidae and Isoptera groups; The NTSV3 area at a depth of 20 to 30 cm provided the best conditions for the highest relative frequency of the Oligochaeta group.

Research implications: The assessment of vertical distribution favored a broader knowledge of the macrofauna community in the systems; The adoption time of the one- or three-cycle no-tillage system did not affect the density and diversity of macrofauna.

Originality/value: Most studies soil macrofauna have been carried out in areas under conventional or no-tillage of grains or in forests, few studies are carried out in areas with irrigated vegetables, where processes involving organic matter reach be three times faster, where the diversity of this macrofauna is higher and needs to be evaluated.

Published: January 2024

Studi mengenai pengelolaan wakaf uang melalui pembiayaan kepada usaha mikro, kecil dan menengah (UMKM) bertujuan untuk memberikan alternatif pengelolaan wakaf untuk kegiatan produktif terutama UMKM dengan meminimalkan risiko tidak kembalinya pokok wakaf. Studi dilakukan dengan menggunakan metode kualitatif deskriptif yaitu melalui studi literatur yang memuat kajian yang pernah dilakukan sebelumnya, skema pembiayaan UMKM yang pernah dilakukan oleh beberapa lembaga yang kemudian penulis modifikasi untuk memperoleh skema pembiayaan UMKM yang memiliki risiko yang relatif rendah. Studi ini menghasilkan kesimpulan bahwa pengelolaan wakaf uang untuk pembiayaan UMKM dapat dilakukan dengan skema supply chain financing (SCF). Skema SCF memiliki risiko yang relatif rendah, karena pembiayaan diberikan atas dasar tagihan UMKM kepada mitra usaha. Untuk usaha skala mikro yang umumnya modalnya masih lemah dan usahanya belum berkembang, pinjaman dapat diberikan tanpa bagi hasil. Sedangkan pembiayaan kepada usaha kecil dan menengah dapat diberikan pinjaman dengan sistem bagi hasil. Studi ini masih terbatas pada pembiayaan UMKM secara umum, ke depan dapat dikembangkan studi lebih lanjut skema pembiayaan UMKM pada sektor ekonomi tertentu atau secara spasial sesuai karakteristik wilayah masing-masing.

Published: January 2024

The current investigation aims to develop a management strategy to enhance the relationship between water and food in the Euphrates River Basin, Iraq. The research methodology utilized the LARS-WG model to generate weather data for the future period (2020–2050) for the CanESM2 model. The weather data was subsequently employed in the CROPWAT model to estimate crop water requirements. Finally, the Water Evaluating and Planning (WEAP) model analyzed the great-inhabitant growth rate scenario (5%), climate change scenarios (i.e., RCP2.6, RCP4.5, and RCP8.5), and management scenarios. The WEAP model was initially calibrated and validated utilizing several statistical metrics, viz., the root mean square (RMS), Nash-Sutcliffe coefficient efficiency (NSE), and the coefficient of determination (R2). Results revealed a superior performance of the WEAP model in terms of the statistical metrics utilized. The findings illustrate that the projected water demand under RCP 2.6, RCP4.5, and RCP8.5 scenarios and the inhabitants growth scenario increased by 49%, 54%, and 56%, respectively, in the year 2050 compared to the reference scenario. In addition, the findings indicate that the water demand would decrease by 59% under the considered management scenario. Accordingly, the investigation recommends implementing water management practices, especially adaptation measures for climate change. Doi: 10.28991/CEJ-2023-09-12-010 Full Text: PDF

Published: January 2024

Construction is a crucial industry that drives a nation's economic growth, yet it often faces inherent challenges related to productivity and waste generation. Lean Construction (LC) has emerged as a promising approach to address these challenges. However, despite its success in various construction projects, some gaps in the practical adoption of LC hinder its widespread practitioner uptake. Therefore, to close the gap, the objective of this study is threefold: identify waste factors of construction activities, determine suitable lean tools for project performance improvement, and assess the impacts of the implementation of lean tools on project completion time and costs. A toll road project in Indonesia was investigated as the case study. A combined research method was employed by administering a questionnaire survey to pertinent project participants, conducting in-depth interviews, and analyzing relevant documents to achieve these objectives. This study discovered 15 non-value-added (NVA) activities that can be eliminated to enhance overall project performance. Most of these activities can be accommodated using coordination and collaboration, while some require a more comprehensive approach, including standardization, the Five S, crash programs, and overlapping techniques. Implementing lean tools resulted in a 19.17% reduction in project completion time, although it contributed to a 5.33% decrease in organizational profit compared to traditional approaches. The findings of this study hold the potential to benefit those facing similar issues, not only in emerging countries but also in developed economies grappling with similar contexts.

Published: January 2024

This research aims to increase the reliability and safety of pipeline systems by creating an improved model range of Butterfly Check Valves (BCV). Pipes through which working fluids are transported, parts related to shut-off and control valves, control measuring instruments, fasteners, anticorrosion elements, and other structural components are the main elements that make up pipelines. Fittings can be of different types; BCV refers to protective ones. These devices protect pipelines by disconnecting the working line in the event of a sudden change in the transported fluid parameters (pressure, flow direction), resulting in the failure of the entire system. Based on an analysis of the key requirements for valves, namely reliability, tightness of a closed system, ensuring safe operation, and analysis of existing BCVs, the design of the presented valve was created. Improved overall dimensions and tightness, both in the open and closed states, as opposed to the existing analogs, are distinctive features of the developed design of butterfly check valves. To confirm the results, the authors, using the finite element method, calculated the stress–strain state of the structure under normal conditions and with regard to the maximum temperatures of the working fluid. The reliability indicators of the developed elements were also calculated to confirm their operability. As a result, it was concluded that after the developed valves have passed acceptance tests, the research findings will make it possible to increase the reliability and safety of the valve itself and the entire pipeline system by introducing these structures into enterprises.

Published: January 2024

Aging reinforced concrete (RC) building structures typically experience more severe damage and are prone to collapse during earthquakes, constituting a primary factor in casualties and direct economic losses. To enhance the seismic performance of these old structures, this paper proposes a seismic risk assessment and a micro-concrete restoration method. It applies the process to an existing three-story reinforced concrete structure. A practical framework for mitigating structural vulnerabilities in seismic-prone regions was proposed. Then an as-built survey was conducted to create as-built architectural and structural drawings. Concrete core tests, ferroscans, and rebar tests were also performed. Based on field surveys and test data, nonlinear static and dynamic analyses have been used to evaluate structural safety. Concrete column jacketing was used to strengthen weak existing columns with micro-concrete. In assessing the structural response of retrofitted buildings, a comparison was made to their initial state. The comparison shows that applying concrete column jacketing with micro concrete can reduce other structural elements' demand capacity ratio (DCR), minimize maximum displacements, and enhance overall stiffness. The results indicate that the proposed method effectively evaluates the seismic risk of aging structures and enhances seismic resilience in existing buildings. Moreover, the application to the actual structure demonstrates that micro-concrete is highly durable and compatible with parent-concrete. Doi: 10.28991/CEJ-2023-09-12-04 Full Text: PDF

Published: January 2024

Problematic soils with high compressibility and low shear strength are often treated with traditional chemical stabilizing additives such as cement and lime to improve their engineering properties. Polymers were employed to improve and reinforce a variety of material qualities in a wide range of applications. The use of polymer SBS (stabilizer base stabilizer) to improve the characteristics of problematic soils is discussed in this research. Two types of soils were used. The first type, "soil A Burj," is collapsible soil and was collected from Burj El-Arab city, while the second type, "soil B Dam," is fine sand and was obtained from Damietta city. The untreated and treated samples were subjected to sieve analysis, hydrometer, liquid limits, standard compaction, collapse potential (CP), direct shear, California Bearing Ratio (CBR) testing, and SEM, TEM, chemical, and microstructural analysis tests. Three different polymer SBS concentrations in water were used (1:300, 1:150, and 1:10). The results showed that by adding the polymer SBS, LL and OWC decreased exhibiting more plastic behavior compared to the non-treated samples. Also, the CP decreased with adding the polymer SBS, and the degree of collapsibility was enhanced from trouble to moderate trouble condition. The shear strength, internal friction angle, and CBR value were also improved. In summary, the best results were produced when a polymer ratio of 1:150 was used and a curing time of at least 28 days was provided. Doi: 10.28991/CEJ-2023-09-12-05 Full Text: PDF
Torsional Behavior of CFRP Strengthening of SCC Box Beams with Web Openings under Repeated Loading
Authors: Mahdi Haneen M. , Abbas Rafaa M. 
Published: January 2024

Monotonic and repeated torsional loading frequently occur in many concrete structures. The loading and unloading action of repeated torsion places structures under greater damage and risk of failure than other types of loading. Therefore, keeping old infrastructure maintained, repaired, and upgraded has become an important priority and requirement. In this research, experimental work was done on pre-cracked self-compacted reinforced concrete box beams repaired (strengthened) with CFRP sheets to investigate the effect of web openings and CFRP sheets on the torsional behavior of tested specimens. Two groups of sixteen half-scale CFRP-strengthened RC box beams with different numbers of circular openings in the web, with a diameter of about 30% of the hollow box depth, were investigated. The first group (I), tested under monotonic torsional loading, comprised four unstrengthened RC beams and another four beams strengthened with CFRP strips, whereas the second group (II) consisted of the same details as the first one tested under repeated loading. The range of the repeated loading was about 30% and 60% of the ultimate load of the monotonic tests. The effect of opening and repairing (strengthening) with CFRP on the ultimate and cracking Torques, Torque-Twist Angle, steel strains, and modes of failure were displayed and discussed. Cracking and ultimate torques and the angle of twist of the tested beams were significantly reduced due to openings in the web, accompanied by increased values for the steel strains due to the presence of openings. However, the results showed that using CFRP strengthening techniques increased torsional strength, angle of twist, and decreased steel strain for all the tested beam specimens. Results revealed that repeated loading causes inelastic deformations in proportion to the number of loading cycles, more than static load deformations. Doi: 10.28991/CEJ-2023-09-12-06 Full Text: PDF
