Published: May 2024

The objective was to evaluate the erodibility of a Dystrophic Red Yellow Latosol from the Mutum Paraná River sub-basin to understand the influence of forest conversion and different pasture temporalities on its physical structure and the potential for sediment release after surface samples undisturbed were subjected to the Inderbitzen experiment. Tests of Mechanical Resistance to penetration and physical parameters under forest and pasture conditions were carried out. A simulation of surface runoff by water spraying (Inderbitzen) was carried out to analyze the disaggregation and transportability of particles. The erodibility equation (K factor) was applied, and the Limits of Consistency were defined to measure the Plasticity Index of the soil that qualifies its erodibility. The pasture samples submitted to the experiment indicated soils of low susceptibility to erosion, even under conditions of maximum slope of the area (17°) and under intense simulated flow (3 L and 6 L min-1) of sprinkler, not showing large losses of sediments or intense surface degradation. There was a relation between soil physical properties and the response of the sample in the experiment. Samples with higher total porosity (r = 0,89) and lower apparent densities (r = -0,88) showed higher disaggregation. There was a significant correlation between the simulated samples that showed lower sediment losses, with a higher percentage of clay (r = -0,65). Samples with a higher percentage of total sand indicated higher percentages of disaggregation (r = 0,68). Erodibility data obtained by the K-factor equation and Plasticity Index endorsed the low soil erodibility

Evaluating Recycled PET as an Alternative Material for the Construction Sector Towards Sustainability
Authors: Albatayneh Omar , Akhtar Mohammad Nadeem
Published: May 2024

Addressing the environmental threat of Polyethylene Terephthalate (PET) waste is critical for sustainable development. Despite PET's prevalence in everyday products, its improper disposal endangers environmental health. This study targets a pivotal gap in current research. PET waste's potential as a sustainable building material will be thoroughly evaluated, focusing on whether recycling PET waste is feasible. In the construction industry, it can be a substitute for natural sand and an additive in cement. This study contributes to a dual-purpose solution: mitigating environmental pollution and innovating in construction material science. The systematic literature review (SLR) delves into existing studies, focusing on PET's impact on concrete properties when substituting natural sand at ratios of 5% to 20% and as a cement additive at 0.5% to 2% by weight. The findings revealed that up to a 10% PET replacement enhances compressive strength, highlighting a sustainable pathway for construction practices. However, replacements above 10% show a reduction in strength, indicating an optimal substitution threshold. Moreover, incorporating PET additives at 1% by cement weight optimizes flexural strength, underscoring the material's viability in enhancing structural integrity. This study sheds light on PET waste's application in reducing environmental impact and proposes a viable, eco-friendly alternative for construction materials. The recommendation for further research underscores the necessity to refine PET's application in construction, aiming to bridge the knowledge gap and encourage sustainable future innovations. Doi: 10.28991/CEJ-2024-010-04-020 Full Text: PDF
Stress Concentration Factors in KT-Joints Subjected to Complex Bending Loads Using Artificial Neural Networks
Authors: Iqbal Mohsin , Karuppanan Saravanan , Perumal Veeradasan , Ovinis Mark , Khan Afzal , Faizan Muhammad
Published: May 2024

Fatigue analysis of tubular joints based on peak stress concentration factor (SCF) is critical for offshore structures as it determines the fatigue life of the joint and possibly the overall structure. It is known that peak SCF occurs at the crown position for in-plane bending (IPB) and at the saddle position for out-of-plane bending (OPB). Tubular joints of offshore structures are under multiplanar bending, comprising IPB and OPB. When a joint is subjected to IPB and OPB loads simultaneously, the peak SCF occurs somewhere between the crown and the saddle. However, existing equations estimate SCF at the crown and saddle only when a joint is subjected to IPB or OPB. It was found that the position and magnitude of peak SCF under simultaneous IPB and OPB depend on the relative magnitudes of these uniplanar load components. The crown and saddle position SCF can be substantially lower than the cumulative peak SCF. Empirical models are proposed for computing peak SCF for KT-joints subjected to multiplanar bending. These models were developed through regression analysis using artificial neural networks (ANN). The ANN training data was generated through 3716 ANSYS finite element simulations. The empirical model was validated using models available in the literature and can determine peak SCF with an error of less than 1.5%. Doi: 10.28991/CEJ-2024-010-04-04 Full Text: PDF
Innovative Method for Reinforcing Beams with Different Types of Concrete Using Cross-Rod Steel Bracing Under Pure Torsion
Authors: Abdullah Adnan I. , Lateef Assim M.
Published: May 2024

This study aimed to investigate the effectiveness of an innovative way to reinforce the concrete beams using cross-rod steel bracing under pure torsion. The experimental program consists of casting and testing eighteen concrete beams made of three types of concrete in the form of three groups, with the same dimensions for all beams (200×200×2000) mm. The parameters of the study included concrete types (normal strength, high strength, and steel fiber), as well as the number of internally cross rods (4, 8, 12, 16, 20). The experimental results showed that the number of internally cross-rod reinforcements and concrete type had an effect on ultimate torque, crack width, toughness, and stiffness. The torsional capacity of all concrete beams increased with the increase in internally cross-rod reinforcement. The ultimate torque of normal-strength concrete beams, high-strength concrete beams, and steel fiber concrete beams reinforced with twenty internally cross rods increased (88.34%, 53.20%, and 40.60%), respectively, compared to beams without cross rods in each type of concrete beam. Increasing the internally cross rod in all concrete beams effectively inhibited the development of crack width and improved torsional stiffness, especially in fibrous concrete beams that contained steel fiber. The torsional toughness of all concrete beams increased with the increase of internally cross-rod reinforcement, and it was higher in steel fiber concrete beams. The steel fiber concrete beams reinforced with internally cross-rod steel bracing have better torsional properties compared to ordinary concrete beams and high-strength concrete beams. Doi: 10.28991/CEJ-2024-010-04-06 Full Text: PDF

Authors: Aslam Mughees , Baffoe-Twum Edmund , Ahmed Muhammad , Ulhaq Aman
Published: May 2024

Construction projects frequently encounter challenges such as stagnant productivity, excessive waste, cost overruns, and delays, contributing to sustainability issues. In response to these issues, Lean Construction (LC) has emerged as a methodology aimed at eradicating inefficiencies and wasteful practices. However, the construction industry has been slow to embrace LC, primarily due to a lack of comprehensive evaluations regarding its real-world effectiveness. This study seeks to thoroughly assess the effectiveness of LC when implemented in construction projects in Pakistan. The research involved conducting a survey among experts in the construction industry, utilizing a comprehensive questionnaire to evaluate the extent of LC adoption and its impact on construction project performance. The collected data underwent rigorous statistical analysis to ascertain the influence of LC practices on project outcomes. To validate the survey results, the study selected five case study projects for in-depth analysis. These case studies assessed how well the projects adhered to LC principles and examined the resulting effects on project delays, cost overruns, quality issues, rework, and health-related concerns. The findings consistently confirmed that a higher level of adherence to LC principles led to significant reductions in project delays, cost overruns, quality issues, and health-related problems. This analysis strongly supports the notion that a more extensive adoption of LC practices results in substantial improvements in project performance. By presenting these compelling results, this study offers valuable insights to the construction industry, providing a clearer path for the effective integration of LC practices. Doi: 10.28991/CEJ-2024-010-04-09 Full Text: PDF
COMPARATIVE ANALYSIS OF THE INHIBITORY EFFECTS OF THE HYPOMAGNETIC FIELD AND COMBINED MAGNETIC FIELDS ON THE PRODUCTION OF REACTIVE OXYGEN SPECIES (ROS) BY NEUTROFILS
Authors: Novikov V. , Yablokova E. , Shaev I. , Novikova N. , Fesenko E.
Published: May 2024

The article reveals that a decrease in the background production of reactive oxygen species (ROS) in the peritoneal neutrophils of mice after a short-term (40 minutes) stay in hypomagnetic conditions (residual field  10 nT) at physiological temperatures, detected by the method of lucigenin-dependent chemiluminescence, is not accompanied by a violation of chemiluminescent response to respiratory burst activators: formylated peptide N-formyl-Met-Leu-Phe (fMLF) and phorbol ester of phorbol-12-meristat-13-acetate (PMA). These results were obtained by activated chemiluminescence using lucigenin or luminol and various combinations of ROS production activators (PMA and/or fMLF). In contrast, the action of combined parallel constant (induction 60 μT) and alternating (amplitude range 60-180 nT, frequency
49.5 Hz) magnetic fields (CMF) leads to a decrease in the chemiluminescent response to these activators. These data indicate different sources of ROS that respond to certain modes of CMF and hypomagnetic field in neutrophils. The conducted research and the previously obtained results enable to exclude the systems that control the respiratory burst in neutrophils from the main targets and acceptors that respond to short-term deprivation of the magnetic field.

Horseshoe crabs (HSC) are marine arthropods, which are protected in Indonesia. Understanding fishermen's perceptions of HSC's existence was very important for the decision-making of conservation planning and management. This research aimed to analyze local fishermen's perceptions toward HSC's existence and the factors influencing their perceptions. Questionnaire-based interviews were conducted with 92 fishermen from the Banyuasin coast, from August to September 2023. Data were analyzed using descriptive statistics and multinomial logistic regression. The results revealed that most fishermen knew HSC and could distinguish their species. The survey of fishing practices showed that the vast majority of respondents operate one-day fishing with only few hours at sea (53.3%), conducting day time operation (69.6%), using 5-10 GT vessels (52.2 %), and deploying fishing gear at the sea bottom (85.9%). Based on fishermen's perception scores toward HSC existence through six assessment aspects, the majority of their perceptions were in the moderate category (54%), followed by the low (28.7%) and high (16.2%) categories. In terms of the regression output, the results of the likelihood ratio test indicated that education, setting position of gear, fishing operation time, and village location were explanatory variables that significantly influenced fishermen's perceptions.

DKI Jakarta Province with a high increase in development activities has implications for the conversion of urban Green Open Space (GOS) into built-up land. The importance of the existence of urban GOS cannot be separated from supporting the development of the green city concept in DKI Jakarta Province. The green city is a concept of realizing a sustainable city and minimizing the degradation of the green city concept in DKI Jakarta Province. Geographic Information System (GIS)- based spatial analysis methods and remote sensing were used to evaluate the availability of urban GOS. Quantitative and qualitative analysis methods based on the Asian Green City Index (AGCI) are used to evaluate the application of the green city concept. The results show that GOS in DKI Jakarta has decreased, from 33.70% in 2000, 23.47% in 2010, and 19.50% in 2020. In the application of the green city concept, the performance of DKI Jakarta has increased. Performance in 2000 was at a below-average level (34.58%), in 2010 it was at the average level (44.85%), and in 2020 the performance increased to an above-average level (62.76%). The results showed that the increase in the implementation of the green city concept has not been followed by an increase in the quantity of urban GOS. An integrative urban planning strategy is needed in developing DKI Jakarta so that it remains oriented towards the carrying capacity of the landscape and maintains the availability of existing urban GOS.

Several facets of sulphonamides are covered in this overview, including their chemistry, history, structure-activity relationship, classification systems, and contemporary synthesis techniques. The review also covers the range of sulphonamides pharmacological effects as antibacterial and antidiabetic agents. Sulphonamides work by competitively limiting microorganisms' ability to produce vitamin Bc, which stops bacteria from proliferating but does not actually kill them and need to be used against a range of fungi and gram-positive and gram-negative bacteria. According to the International Diabetes Federation's global cartographic image of diabetes (http://www.diabetesatlas.org/), type 2 diabetes mellitus (T2DM) is a pandemic that affects people worldwide. Hyperglycemia is the primary symptom of diabetes mellitus, a chronic, progressive, and poorly understood metabolic disease and discussed the mechanisms of metformin, glitazones, sulphonyl urea’s and other agents. Worldwide, copious research has been conducted on molecular targets associated with type 2 diabetes, including PPAR-γ, incretin, GLP-1, DPP-4, and SGLT2, DPP-IV, GSK-3, Aldose-reductase, fructose-bisphosphatases, and β3 adrenoceptor are used to treat type 2 diabetes.

Utilizing the tooth coronal pulp index for age estimation: A retrospective cone beam computed tomography study
Authors: Saraswathi Gopal K  , Sumithra A
Published: May 2024

Background: Age estimation through teeth is one of the most reliable method as teeth are hardest part of body and could be preserved for long time without gross changes. Thus, age estimation from tooth coronal index using CBCT is based on reduction in size of dental pulp cavity with advancing age as a result of secondary dentin deposition. Aim: To evaluate dental age assessment reliability through Tooth Coronal Index (TCI) method Methodology: A retrospective study involving 60 CBCT images from age group of 20 to 60 years were retrieved from department data base. The age groups were divided into eight groups (Group I – VIII). Mandibular canine, 2nd premolar and 1st molar either of one side is considered. The height of crown and height of coronal pulp cavity were calculated and TCI was measured for each tooth. Age estimated was compared with chronological age to evaluate reliability of age assessment through TCI. Statistical analysis was done using SPSS version 19. Results: Negative correlation was observed between real age and TCI of mandibular 1st molar, mandibular 2nd premolar and mandibular canine. Thus, best dental age estimation was obtained in age group of Group I and VIII. Conclusion: Teeth are more resistant to thermal, chemical and mechanical stimuli and thus considered as one of the reliable indicators. Thus, Tooth coronal index can be considered as one of the reliable parameters in estimating age of individual because of its accuracy.

This study examined foreign market network and internationalization of domestic firms. It was carried out to identify the contemporary foreign-market networks available for domestic firms seeking internationalization; the ways in which foreign market network facilitates the internationalization of domestic firms; and the major barriers to the internationalization of domestic firms in contemporary extant literature. To that end, a systematic literature review methodology was adopted. Through a thorough search process supported by a set of stringent inclusion-exclusion criteria, 103 relevant articles were included in this review. The articles were analyzed using in-depth content analysis method augmented with descriptive statistics. The study found that the contemporary foreign-market networks for internationalization can be grouped into 18 categories. It was also found that foreign market network can enhance the internationalization agenda of domestic forms by providing access to distribution channels, risk mitigation, and enabling access to market knowledge and insights, among other key findings. Therefore, the study recommended the following, among others: Domestic firms seeking to internationalize should seek out foreign market networks using personal contacts, social media and the internet generally in order to gather substantial market intelligence about the countries to which they intend to expand their operations; and domestic firms can leverage foreign market networks by establishing strategic partnerships with local distributors, leveraging international trade associations, and utilizing cross-border collaborations to gain market insights, access distribution channels, and build relationships with key stakeholders, facilitating the successful execution of their internationalization strategy.
