Reducing Reinforced Concrete Materials Waste in Construction Projects Using Building Information Modeling in Egypt
Authors: Hosny Suad , Ibrahim Ahmed Hussein , Nabil Yasmin
Published: May 2023

Reduced Reinforced Concrete Material Waste (RRCMW) is recognized as a major issue that must be controlled in building projects. The primary goal of the study is to demonstrate the significance of BIM in construction and the importance of BIM in reducing reinforced concrete material waste. To achieve the study's goal, a questionnaire survey is undertaken to estimate the benefit of using BIM in Egyptian building projects. According to the survey results, about 41% of respondents are believed that BIM may reduce project costs by 16% to 20% when compared to the traditional method. In addition, the proportion of variations in reinforced concrete amount survey between traditional methods (AutoCAD) and (Revit) is discovered to be 44%, with a range of 11% to 15%. Approximately 46% of respondents are believed that BIM eliminates design errors, with a percentage ranging from 21% to 25%, and about 51% are believed that BIM helps in reducing rework, with a total percentage ranging from 21% to 25%. Then, case studies of building ("Residential projects") and infrastructure ("Bridges projects") projects are analyzed to determine the difference between waste minimization using traditional methods and waste minimization using BIM. Waste management is a critical issue since it is the only approach to optimize waste throughout the project phases. As a result, factors managing (RRCMW) are extracted, and BIM software should be used to manage these factors in order to optimize waste. The relevant BIM applications are used in this case study: site utilization planning, quantity take-off, 3D coordination, visualization, digital prefabrication, design validation, "design review and clash detection," and optimized workflow and communication structure. So, based on the preceding case studies, it is discovered that using BIM is far more successful and economical than using the traditional method, because it aids in the resolution of many issues before and during construction, such as clash detection, material storage, material ordering, and so on. As a result, while BIM is not widely used in Egypt, engineers should be familiar with it because it will be a vital tool to reduce waste in the future.

It is indicated that contracts for the integrated performance of work are one of the most common forms of concluding agreements in the activities of organizations of various forms of ownership. The authors present the consequences of a violation of the integrated performance of work on the activities of the enterprise. The development of the engineering market has a positive impact on the performance of the firm and the introduction of new digital technologies. Attention is paid to companies in the oil and gas sector, which occupy a significant volume of the segment and have proven methods of project implementation, developed cooperation with leading organizations and access to financing. Limitations of liability and risks of intermediary distribution of work, focus on diversification of risks and the role of legislative initiatives in the field of research are indicated. The reformatting of the design and technological infrastructure directly depends on the use of digital technologies in business processes. Reengineering allows you to improve the ability to follow the strategic goals of the organization, increase the creation of added value and organizational efficiency, and solve the problems of low technological readiness of production entities. At the same time, business process engineering depends on the industry in which the company operates, the efficiency of operations and the cost of engineering software for modern modeling. Risk diversification of process engineering and reengineering is limited by capital costs, the nature of the business model, market conditions, ownership structure, and project performance evaluation. The article summarizes the impact of the digitalization of technological engineering and reengineering on improving productivity by reducing transaction costs, reducing project lead time, and improving the business model.

Authors: Putri Nora Eka , Helmi . , Noer Melinda , Yossyafra .
Published: May 2023

This research is related to the social phenomenon of land acquisition for toll road construction. It is necessary to enrich knowledge about policy politics, especially in the decision-making process of land acquisition policies, by involving the participation of widely affected communities (hybrid policy). The implementation of land acquisition for the Sicincin-Padang toll road construction in West Sumatra relatively encounters challenges such as issues of compensation, disputes over customary land, coordination between stakeholders, and such. The purpose of this research is to formulate a hybrid policy model for the decision-making process of land acquisition for the construction of toll roads in West Sumatra. The research approach is a mixed method, a kind of concurrent triangulation, namely two-sided research conducted simultaneously so that both sides have the same emphasis (data collection and analysis techniques). Data were collected from relevant informants and respondents from affected communities (325 respondents). Data were analyzed using a soft system methodology consisting of root definition, customers, actors, transformation, worldview, owners, and environmental constraints (CATWOE) analysis. The study results explain that the implementation of land acquisition for toll roads in Indonesia and the Sicincin-Padang section of toll roads in West Sumatra has not been optimal; there are still problems such as refusal of compensation value, road alignment issues, land acquisition administration, and coordination between the central government, local government, and the community. Furthermore, based on the above findings, a hybrid policy model for land acquisition policy (especially at the planning stage) is formulated as a novel concept that can be an alternative solution to the problem of toll road land acquisition.

The Dakwah Communication Model of the Post-Persecution Muslim Minority: The Case of the Restoration of the Indonesian Ahmadiyya Congregation (JAI)
Authors: Ma`arif Bambang Saiful , Rahmat Munawar , Kastolani .
Published: May 2023

Ahmadiyya is a Muslim minority with distinctive teachings contradictory to mainstream Islam that has been entrenched in Indonesia since the Dutch colonial era. After independence, the sect enjoyed the freedom of religion and belief under the law's guarantee and the state's power during the reign of the first two presidents (1945-1998). However, the power of orthodox Muslims strengthened during the Reformation Order, and in 2005, a fatwa regarding the heresy of the Ahmadiyya was issued by the Indonesian Ulema Council (MUI). This was followed by the Joint Decree of the Three High State Institutions, which limited the movement of the Indonesian Ahmadiyya Congregation (JAI). Regional regulations emerged, followed by a violent crusade against this sect. Consequently, this research examined the communication model used by the Ahmadiyya Muslim minority to preach post-persecution. The qualitative methods employed for data collection were observation, interviews, and documentation, which intensively occurred in October-December 2019 and August 2022. The respondents were six JAI central/branch managers and three missionaries. The research results show that the Ahmadiyya teachings naming Mirza Ghulam Ahmad (MGA) as a prophet are the trigger for persecution. Although orthodox Muslims allow the unhindered performance of activities, providing Ahmadiyya is labeled a religion and not a part of Islam, JAI refused because it believes MGA is the non-shari'at Prophet. After the persecution, JAI proposed four models of dakwah communication that internally strengthen Ahmadi beliefs and invite sympathy and new converts.

Published: May 2023

Global culture is currently still growing and developing massively in countries all over the world. It allegedly causes more harm to develop countries, including Indonesia. It is feared that Indonesia will increasingly lose its national identity, which should be maintained. To date, some Indonesians think that values from foreign countries are the best, while local cultural values are outdated. This research aimed to assess the Sundanese cultural values as part of Indonesian culture to be used as a reference for developing indicators of achieving character education goals, especially for elementary school students. The method used was an exploratory method with an ethnographic approach. The stages of research were: 1) observing the socio-cultural activities of Naga Village community related to the cultivation of family educational values; 2) creating descriptive narratives in the context of cultivating parental educational values for their children in Naga Village community; and 3) analyzing the findings on the educational values in Naga Village community to be integrated into the development of the indicators of educational character values at elementary schools. The research findings indicated that in the perspective of Sundanese cultural wisdom, to become a human with character, from an early age, children should be instilled with the character values of obedience, patience, humility, honesty, sociability, and deliberation. These values could be integrated for the development of the indicators in achieving learning objectives to shape the character of elementary school students.

On the Spectral Radius of Minimally 2-(Edge)-Connected Graphs with Given Size
Authors: Lou Zhenzhen , Min Gao , Huang Qiongxiang
Published: May 2023

A graph is minimally $k$-connected ($k$-edge-connected) if it is $k$-connected ($k$-edge-connected) and deleting any arbitrary chosen edge always leaves a graph which is not $k$-connected ($k$-edge-connected). Let $m= \binom{d}{2}+t$, $1\leq t\leq d$ and $G_m$ be the graph obtained from the complete graph $K_d$ by adding one new vertex of degree $t$. Let $H_m$ be the graph obtained from $K_d\backslash\{e\}$ by adding one new vertex adjacent to precisely two vertices of degree $d-1$ in $K_d\backslash\{e\}$. Rowlinson [Linear Algebra Appl., 110 (1988) 43--53.] showed that $G_m$ attains the maximum spectral radius among all graphs of size $m$. This classic result indicates that $G_m$ attains the maximum spectral radius among all $2$-(edge)-connected graphs of size $m=\binom{d}{2}+t$ except $t=1$. The next year, Rowlinson [Europ. J. Combin., 10 (1989) 489--497] proved that $H_m$ attains the maximum spectral radius among all $2$-connected graphs of size $m=\binom{d}{2}+1$ ($d\geq 5$), this also indicates $H_m$ is the unique extremal graph among all $2$-connected graphs of size $m=\binom{d}{2}+1$ ($d\geq 5$). Observe that neither $G_m$ nor $H_m$ are minimally $2$-(edge)-connected graphs. In this paper, we determine the maximum spectral radius for the minimally $2$-connected ($2$-edge-connected) graphs of given size; moreover, the corresponding extremal graphs are also characterized.

The study employed a quantitative and deductive approach. The questionnaire was used as a data collection instrument. Data were gathered from a random sample of 150 respondents, comprising millennial entrepreneurs in Malaysian public universities, aged 22 to 38 years old and with at least three years of business experience. Proposed hypotheses were tested using Multiple Regression analysis. The findings reveal the significant and positive effect of innovation, risk-taking, and proactive on Muslim millennial SMEs' success, implying that a higher level of innovation, risk-taking, and proactive, is more likely to yield in Muslim millennial SMEs' success. Thus, Muslim millennial SMEs' success can be generated by instilling entrepreneurial spirit. In addition to empirical evidence, the findings provide fresh insights into how entrepreneurs can formulate strategies to achieve business success.
The challenges posed to Community/Public-service Interpreting by the introduction of ‘Plurilingual Mediation’ in the new Companion Volume to the Common European Framework for Languages
Authors: Runcieman Alan
Published: May 2023

The new Companion Volume (CV) to the Common European Framework for Languages (CEFR) has significantly amplified the importance of mediation as a plurilingual language activity within its conceptualisation of communicative competence. This is to be warmly welcomed as a positive contribution to, and acknowledgement of, increasingly superdiverse plurilingual societies and the potential for multilingual language users/learners to act as ‘social agents’ in complex inter-lingual/cultural settings. However, this article wishes to raise a few important issues that need to be addressed in the new CV as, it is argued here, they have the potential of having a negative impact on the field of Community/Public-Service interpreting.

Purpose. This study was conducted to investigate possible risk factors that could increase the occurrence of drug-resistant epilepsy (DRE), in hopes that the results could be used to educate the patient and their caregivers as well as increase early detection efforts. Methods. Case control study was conducted at neurology outpatient pediatric RSDS between May to December 2022. Risk factor of DRE such as sex, age of onset, type of seizure, initial seizure frequencies, history of cranial hemorrhage, cerebral infection, febrile seizure, status epilepticus, neonatal seizure, neonatal asphyxia, family history of epilepsy, present of neurological deficit, electroencephalogram (EE) finding, and result of neuroimaging examination were obtained through anamnesis and clinical examination. Risk factors were analyzed with bivariate analysis and multivariate analysis. A model was generated to predict probabilities of DRE in children with epilepsy. Results. DRE was observed in 84/137 (54%) patients. Bivariate analysis showed age of onset <1 years old (OR 2.31, p = 0.016), initial seizure frequencies >5 times/day (OR 3.0, p = 0.011), neonatal seizure (OR 3, p = 0.034), presence of neurologic deficit (OR 3.1, p=0.002), and abnormality of EEG (OR 2.82, p = 0.013) are significantly associated with DRE. Logistic regression revealed that initial seizure frequencies > 5 times/day (OR=2.5; 95%CI 1.051 to 6.028; P=0.038), present of neurological deficit (OR=2.58; 95%CI 1.205 to 5.531; P=0.031), and EE abnormality (OR=2.84; 95%CI 1.170 6.914; P=0.021) were significantly correlated with DRE. Our model sensitivity was 75.3% and 55.76% to predict DRE (AUC = 0.704, p=0.000). Conclusion. Seizure onsets of >5 times, neurological deficits, and EEG abnormality were found to be associated with drug resistant epilepsy.

Among the supernovae (SNe) that show strong interaction with a circumstellar medium (CSM), there is a rare subclass of Type Ia supernovae, SNe Ia-CSM, which show strong narrow hydrogen emission lines much like SNe IIn but on top of a diluted Type Ia spectrum. The only previous systematic study of this class identified 16 SNe Ia-CSM, eight historic and eight from the Palomar Transient Factory (PTF). Now using the successor survey to PTF, the Zwicky Transient Facility (ZTF), we have classified 12 additional SNe Ia-CSM through the systematic Bright Transient Survey (BTS). Consistent with previous studies, we find these SNe to have slowly evolving optical light curves with peak absolute magnitudes between −19.1 and −21, spectra having weak Hβ and large Balmer decrements of ∼7. Out of the 10 SNe from our sample observed by NEOWISE, nine have 3σ detections, with some SNe showing a reduction in the red wing of Hα, indicative of newly formed dust. We do not find our SN Ia-CSM sample to have a significantly different distribution of equivalent widths of He i
λ5876 than SNe IIn as observed in Silverman et al. The hosts tend to be late-type galaxies with recent star formation. We derive a rate estimate of

Gpc−3 yr−1 for SNe Ia-CSM, which is ∼0.02%–0.2% of the SN Ia rate. We also identify six ambiguous SNe IIn/Ia-CSM in the BTS sample and including them gives an upper limit rate of 0.07%–0.8%. This work nearly doubles the sample of well-studied Ia-CSM objects in Silverman et al., increasing the total number to 28.
On the Reionization-era Globular Cluster in the Low-mass Galaxy Eridanus II
Authors: Weisz Daniel R. , Savino Alessandro , Dolphin Andrew E.
Published: May 2023

Using color–magnitude diagrams from deep archival Hubble Space Telescope imaging, we self-consistently measure the star formation history of Eridanus II (Eri II), the lowest-mass galaxy (M
⋆(z = 0) ∼ 105
M
⊙) known to host a globular cluster (GC), and the age, mass, and metallicity of its GC. The GC (∼13.2 ± 0.4 Gyr, 〈[Fe/H]〉 = −2.75 ± 0.2 dex) and field (mean age ∼13.5 ± 0.3 Gyr, 〈[Fe/H]〉 = −2.6 ± 0.15 dex) have similar ages and metallicities. Both are reionization-era relics that formed before the peak of cosmic star and GC formation (z ∼ 2–4). The ancient star formation properties of Eri II are not extreme and appear similar to z = 0 dwarf galaxies. We find that the GC was ≲4 times more massive at birth than today and was ∼10% of the galaxy's stellar mass at birth. At formation, we estimate that the progenitor of Eri II and its GC had M
UV ∼ −7 to −12, making it one of the most common type of galaxy in the early universe, though it is fainter than direct detection limits, absent gravitational lensing. Archaeological studies of GCs in nearby low-mass galaxies may be the only way to constrain GC formation in such low-mass systems. We discuss the strengths and limitations in comparing archaeological and high-redshift studies of cluster formation, including challenges stemming from the Hubble Tension, which introduces uncertainties into the mapping between age and redshift.
Inflation from Multiple Pseudo-scalar Fields: Primordial Black Hole Dark Matter and Gravitational Waves
Authors: Talebian Alireza , Hosseini Mansoori Seyed Ali , Firouzjahi Hassan
Published: May 2023

We study a model of inflation with multiple pseudo-scalar fields coupled to a U(1) gauge field through Chern–Simons interactions. Because of parity-violating interactions, one polarization of the gauge field is amplified, yielding to an enhanced curvature perturbation power spectrum. Inflation proceeds in multiple stages, as each pseudo-scalar field rolls toward its minimum, yielding to distinct multiple peaks in the curvature perturbation power spectra at various scales during inflation. The localized peaks in the power spectra generate primordial black holes that can furnish a large fraction of dark matter abundance. In addition, gravitational waves with nontrivial spectra are generated that are in the sensitivity ranges of various forthcoming GW observatories.

Accessing the potentially habitable subsurface waters of Ocean Worlds requires a robotic ice probe (or “cryobot”) to traverse tens of kilometers of ice with temperatures ranging from ∼100 to 273 K. Designing and planning such a mission requires understanding ice probe behavior as a function of the local environment and design parameters. We present experimental results of two laboratory melt probes in cryogenic (79 K) and warm (253 K) ice. The melt probe tested in warm ice had multiple adjustable heaters, enabling optimization of the system's efficiency. The melt probes tested in cryogenic ice operated in vacuum and had internal tether spools, allowing for experimental confirmation of hole closure and the creation of a pressurized pocket with liquid water around the probe. These melt probes were tested at power levels ranging from 120 to 1135 W, achieving descent speeds between 5.3 and 59 cm hr−1. By analyzing the relationship between power and speed using analytical and high-fidelity numerical models, we demonstrate progress in understanding melt probe performance. We distinguish between the previously confounding terms of probe operational inefficiency and analytical model inaccuracy, allowing us to understand the range of applicability of the analytical models and demonstrate the importance of controlling heat distribution in cryobot design. The validated models show that while numerical models may be required to describe the behavior of short probes descending in limited-size laboratory test beds, the performance of efficient cryobots designed for operation on Ocean Worlds can be predicted by analytical models within 5% error.

The objective of this study was to determine the taxonomic composition and ecological aspects of decapod crustacean species belonging to the infraorders Anomura and Brachyura in shallow marine and estuarine waters from southern Bahia, a coastline about 640 km in extent, corresponding to approximately 7% of the Brazilian coast. Sixteen species of the infraorder Anomura and 68 of the infraorder Brachyura are reported for the study area. The most important families in terms of number of species were the Panopeidae with 11 species, and the Ocypodidae and Portunidae with 9. Among the Brachyura, the southern distribution of the species Austinixa leptodactyla Coelho, 1997 (Pinnotheridae), endemic to Brazil, is extended from the coast of Sergipe to Bahia (Prado, Cumuruxatiba Beach, 17°06'18.6"S, 39°10'50.4"W). The ocypodid Uca (Leptuca) cumulanta Crane, 1943 and also the pinnotherids Austinixa aidae (Righi, 1967) and Fabia byssomiae (Say, 1818) are reported for the first time from the Bahia coast. The specimen of F. byssomiae examined was collected in the mantle cavity of the clam Macoma constricta (Bruchière, 1792) (Bivalvia: Tellinidae), a new host record for the species.

Authors: Silva Alfonso , Oliva Marcia
Published: May 2023

Chilean flounder (Paralichthys adspersus) are endemic to the Chilean coast and have been the subject of several studies on the possible diversification of marine aquaculture. This paper reviews the diverse results obtained from studies of this species` biology and cultivation techniques. The biological and technical knowledge available is sufficient for developing the entire life cycle of this species, producing commercialsized individuals, in captivity. However, this knowledge is disperse and the results, as compared with those for other harvested species, still show moderately reproducible results, impliying the need to continue efforts to optimize some aspects of Chilean flounder cultivation, thereby promoting the species` development definitely.

Authors: Sato Natalia E. , Hernández Daniel , Viñas María D.
Published: May 2023

The diet of Noctiluca scintillans was determined using samples collected monthly at a permanent coastal station off Buenos Aires Province, Argentina (Station EPEA) from March 2000 through April 2001. A total of 1100 individuals were examined. Diatoms (27.7%), copepod eggs (24,1%), and tintinnids (17.9%) were the main prey items. The genus/species of the most abundant preys found in the N. scintillans food vacuoles were, in declining order, the tintinnids Tintinnopsis spp., Codonellopsis spp., and Tintinnidium spp.; copepod eggs of Calanoides carinatus, Ctenocalanus vanus, and Oithona nana; and the diatoms Coscinodiscus wailesii, Paralia spp., Guinardia flaccida, Thalassiosira spp., Pinnularia spp., Pleurosigma normanii, and Triceratium spp. The alimentary incidence varied between 27.5% and 77.0%, with an average of 50.2%. This index reached a high value in the month of September 2000. The correlation between the volumes of predators and preys was highly significant (r = 0.1921; P < 0.00000). The results indicated that N. scintillans is a predator opportunist.

Published: May 2023

Zooplankton were studied from 16 oceanographic surveys carried out in Magdalena Bay, Baja California Sur, Mexico, between August 1997 and March 2001. Twenty-six taxonomic groups were identified, the most abundant and frequent of which were copepods and chaetognaths. In 2000-2001, the number of zooplankton groups tended to decrease by 10 to 20. Both zooplankton biomass and copepod abundance declined, unlike chaetognaths, which increased slightly. Fluctuations in zooplankton abundance were independent of the chlorophyll-a concentration, whereas the maximum zooplankton abundances were associated with changes in the sea surface temperature. The seasonal zooplankton abundance cycle in Magdalena Bay indicated that, in winter, the averaged was than 65,000 ind 100 m-3, a value that increased to more than 99,000 ind 100 m-3 in spring, remained around 100,000 ind 100 m-3 in summer, and decreased rapidly to nearly 40,000 ind 100 m-3 in autumn.
Modification of the spermatic structure of the crab Cancer setosus (Molina, 1782) (Decapoda: Brachyura) during induced acrosomal reaction
Authors: Goldstein Merari , Dupré Enrique
Published: May 2023

The spermatozoon of Cancer setosus consists of a spherical acrosome and a cup-shaped nucleus surrounding the lowest zone of the acrosome and widening at the equatorial area of the acrosome. The spermatozoa extracted from the seminal receptacle of the female and placed in sea water for 15 min underwent the acrosome reaction, which started with the elongation of the acrosomal vesicle followed by the extrusion of its contents. Subsequently, the perforatorium projected forward ≈ 1µm beyond the apical end of the extruded acrosomal vesicle contents, forming an acrosomal filament with a trident-shaped structure on the apical end.
First record of morphological abnormality in embryos of Urotrygon rogersi (Jordan & Starks, 1895) (Myliobatiformes: Urotrygonidae) in the Tropical Eastern Pacific
Authors: Mejía-Falla Paola A. , Navia Andrés F. , Muñoz Luis A.
Published: May 2023

This is the first report of morphological abnormalities in embryos of Roger's roundray Urotrygon rogersi in the Tropical Eastern Pacific. The embryos of two pregnant females caught in artisanal shrimp trawl nets had incomplete, deformed pectoral fins that were separated from the head along the anterior margin. Moreover, one of the embryos presented a fin-like extension in the dorsal surface. Although the mouths of the embryos were normal and well-formed, the malformations in the pectoral fins could affect their mobility, limiting their capacity to capture preys and escape of predators.

This study aimed to map the world's scientific production of bacterial and fungal microbiota in mollusks. The research was carried out in the Web of Science database, using "Fungi AND Mollusk" and "Bacteria AND Mollusk" descriptors and publication time between 2001 and 2021. Indexes were built by years, countries, research areas, and two maps of the co-occurrence of terms. There was a progressive increase in the production of microbiota in mollusks, with more research on bacteria during the investigated period. China and USA were the countries with the highest percentage of publications. Research with fungi and bacteria accounted for 28.41 and 17.66% in China, respectively. While the USA, the percentage was 21.05% for fungi and 16.02% for bacteria. Areas such as marine and freshwater biology (24.77%), fisheries (23.86%), biochemistry and molecular biology (18.60%), and pharmacy (17.83%) showed a higher percentage of indexed articles. There was also a high concentration of deposits of publications in the immunology area for both themes. The groups formed for bacteria and fungi indicated that studies had described the immune responses of mollusks, the genetic aspects associated with their defense mechanisms, pathogen virulence factors, and symbiotic and pathogenic microbiota, highlighting genera Vibrio, Aspergillus, and Escherichia coli pathogenic pathotypes. The bacterial and fungal microbiota in mollusks have been studied in several areas of knowledge and have given rise to research that can support the proper management of mollusks, application in the pharmaceutical industry, and implementation of measures in public health.

Ractopamine is a drug used as an additive in animal production to improve growth, body composition, and production efficiency, although its use in fish is still poorly known. This study aimed to evaluate ractopamine hydrochloride (RAC) effects at increasing levels (0, 10, 20, and 40 mg kg-1) in Nile tilapia (Oreochromis niloticus) diets during 40 days by considering growth performance, body composition, and muscle fiber morphometry. One hundred and twelve fish (mean initial weight 518.63 ± 5.49 g) were housed in 16 circular tanks (450 L), following a completed randomized design with four treatments and four replicates. Body composition was significantly affected (P < 0.05), and the content of lipids in fish fillets dropped 26.7% (20 mg kg-1 RAC) and 26.1% (40 mg kg-1 RAC), as well as the amount of unsaturated fatty acids C14:0 and C18:0 in fish fillets (P < 0.05) by treatment with 10 mg kg-1 of RAC. Results demonstrate that fish fed 20 mg kg-1 RAC for 40 days changed Nile tilapia fillet chemical composition, decreasing lipid levels, altering the fatty acid profile, and increasing protein levels. RAC did not affect any productive performance parameters evaluated for muscle fiber morphometry.
