Abstract Good quality concrete is concrete whose basic ingredients are also of good quality. One of the ingredients that make up concrete that determines the compressive strength of concrete is coarse aggregate. Coarse aggregate itself is a resource that is easy to obtain, widely available in nature and in various types. According to its origin, coarse aggregate used as a building material for concrete can be divided into two, namely natural aggregate obtained from rivers and artificial aggregate obtained from crushed stone. This research was carried out using 3 variations, namely 100% Kali Manggaran stone, 100% Tapa Utama crushed stone, and a combination of 50% Manggaran 50% Tapa Utama with a plan to use concrete quality K225 or 18.68 MPa, according to the minimum requirements of the concrete quality plan for structural work. The results of the research show that the use of 100% Manggaran river stone at a concrete age of 14 days is 14,834 MPa and 18,117 MPa. Meanwhile, the use of 100% crushed stone tapa Utama obtained a concrete compressive strength of 17,256 MPa at a concrete age of 14 days and 21,045 MPa at an age of 28 days and was in accordance with the planned concrete quality. The maximum compressive strength is the 100% crushed stone tapa Utama concrete variation with a concrete age of 28 days. Keywords: Coarse Aggregate, Compressive Strength of Concrete, Manggaran River Stone, Tapa Utama Crushed Stone

Abstract The use of flow concrete is the main choice in construction because of its high workability that facilitates compaction. In this study, utilizing corn cob ash as a partial substitution material for cement because the content of corn cob ash makes the waste potentially used as a concrete mixing material. One of the most important silica content in concrete is silica (SiO2). Corn cob ash has a fairly high silica content of 59%. Silica plays an important role in concrete because it can increase the compressive strength of concrete. This study aims to determine the effect of corn cob ash with variations of 0%, 4%, 5%, 7%, 9% on the compressive strength of flow concrete with a proportion of superplasticizer 1.5% at the age of 7, 21, and 28 days. From the results of the study, it can be concluded that the maximum compressive strength of concrete is in the CCA mixture of 7% at the age of 28 days of concrete, which is 35.22 MPa. The compressive strength of concrete with a mixture of 0% to 7% CCA continues to increase in each life of concrete. Based on the results of this study, corn cob ash as a partial substitution of cement can affect the compressive strength value of concrete. Keywords—Flow Concrete, Corn Cob Ash, Compressive Strength of Concrete

Abstract The exploration of natural materials to produce concrete has an impact on environmental conditions and global warming that can cause natural disasters. Therefore, the use of concrete materials must be as efficient as possible. One solution to overcome this problem is to reduce the concrete in the tensile area and strengthen the beam using steel reinforcement in the support area. This study aims to determine the effect of tensile reinforcement on the behavior of beams without concrete in the tension area using a spiral system on crack patterns and beam patterns. The method used was an experimental method by making 2(two)specimens, a normal concrete beam (BN) as a control beam, and a spiral concrete beam without reinforcement in the tensile section with the addition of experimental reinforcement at the support section (BTRS 60D) where D is the diameter of the main reinforcement. The beams were designed as normal quality concrete beams with concrete quality of 45.07 MPa at the testing age of 28 days. The beam's dimension was 150 mm x 200 mm x 3100 mm. This study obtained the ultimate load on the BTRS specimen of 35.1 kN. While on the BN specimen, the ultimate load reached 47.65 kN. There was a decrease in BTRS service load by 27.57%. It is observed that the BN specimen experienced flexural cracks. The beam failure of the 2 test objects experienced beam failure that resembled under-reinforced where the reinforcing steel melted before the concrete was crushed. Keywords: spiral reinforcement, failure pattern, crack pattern.

Exploring the Factors Behind Romantic Relationship Conflicts Among University Students: A Case of Mukuba University
Authors: Chanda Lazarous 
Published: September 2024

The study sought to investigate the factors behind romantic relationship conflicts among university students. This was a case study conducted at Mukuba University. The target population was undergraduate students at Mukuba University. The sample was selected using quota sampling technique; thus, participants were selected from different schools and year of study based on their romantic relationship status. Those who had not experience romantic relationships were not part of the study. The sample size of the study was 15 students drawn from three schools. The data were collected using face-to-face interviews with the selected students. The study identified six overarching themes, including communication issues, insecurity, time management and priorities, intimacy and sexual matters, financial issues, and cultural or religious disparities as the causes and types of conflicts. The study also revealed that communication conflicts stem from partners ignoring, providing the silent treatment, or encountering communication ambiguity. Insecurity issues arise from incidents of infidelity, suspicion, and possessiveness, while time and priority conflicts result from imbalances between academic commitments and the partners' quality time together. Moreover, the study sheds light on conflicts related to differences in sexual desires and financial discrepancies. Financial challenges include concerns about overdependence on partners for support or materialistic attitudes, often leading to conflicts. Religious and cultural disparities are also influential, as participants experienced relationship strain due to differing beliefs. Furthermore, the investigation explored the outcomes of these conflicts, categorizing them into emotional, relational, academic, mental health, and social impacts. Conflicts triggered anxiety, depression, and stress, affecting relationship stability and leading to decreased feelings of love and connection, breakup, or relationship resilience. Additionally, conflicts negatively affected academic performance and concentration, leading to stress-related physical symptoms and social isolation among individuals experiencing relationship conflicts. The coping mechanisms employed by individuals were categorized into maladaptive strategies like abuse or escapism and adaptive strategies such as seeking support and self-care/stress management. Maladaptive strategies involved aggressive behaviors and avoidance, while adaptive mechanisms included seeking external support or engaging in self-care activities as a means to manage conflict-induced stress. This study contributes to the understanding of conflicts in romantic relationships, emphasizing the complexity and diverse impact of these conflicts on individuals involved.

This study examined the environmental effects of oil spillage in Nembe, Bayelsa State by determining the particle size distribution of the soil, determining the nutrients composition of the soil contaminated with oil spill and the soil of a nearby control site in the study area, comparing the composition of the soil from the polluted site and that from the control site, and comparing the heavy metal present in the polluted soil in the study area with the NESREA standards. The study adopted laboratory research design in generating data for the analyses. Ten samples each were collected from two communities in Nembe, Okoroba and Etieme both from top soils and at depth. From the analyses it was found that there is a slight but insignificant variation on the pH of the soils, which averaged from the (top soil) 6.12 and 5.73 for the control Etieme and the affected soil of Okoroba respectively. The soils are all slightly acidic and this acidity cannot be attributed entirely to the oil spill since the control is equally acidic. Soil gotten from the top at Okoroba had a loamy sand (LS) texture. This has a a high proportion of sand, while the sub soil gotten from the same location had a silt loam (SL) texture, with a balanced mixture of s and, silt and clay. Soil gotten from the top at Etieme had a silt loam texture while the subsoil had a silt clay loam texture(SCL), which contain a high proportion of clay compared to sand and silt. This fraction averaged 66.72% in Etieme soil and 76.72% in Okoroba soil while clay decreased from 21% in Etieme to 16.70 in Okoroba. From the test of hypothesis, it was found that the oil spill concentration of the soil in the polluted site and the soil in the control site are not significantly different from each other; also the heavy metal concentration of the soil in the polluted site did not significantly deviate from the NESREA standards. Nevertheless, it should be known that heavy metals have the ability to bio-accumulate and biomagnify, hence the metal concentrations of this site will come to deviate from that of the NESREA standards over time if precautionary measures are not taken. It was also confirmed that oil spill has detrimental effect on both man and his environment. Comparison of the analytical data gotten from the polluted soil with the data gotten from the control nearby soil shows that there was no significant difference between the soil nutrient in the polluted site and the soil in the control site. The study therefore concluded that effect of oil spill on land as an aspect of the environment in Nembe is still minimal hence the need to urgently tackle the problem of oil spill was recommended so as to nip these negative effects by the bud before it goes out of hand.

Abstract
We present phase-corrected photometric measurements of 88 Cepheid variables in the core of the Small Magellanic Cloud (SMC), the first sample obtained with the Hubble Space Telescope's (HST) Wide Field Camera 3, in the same homogeneous photometric system as past measurements of all Cepheids on the SH0ES distance ladder. We limit the sample to the inner core and model the geometry to reduce errors in prior studies due to the nontrivial depth of this cloud. Without crowding present in ground-based studies, we obtain an unprecedentedly low dispersion of 0.102 mag for a period–luminosity (P–L) relation in the SMC, approaching the width of the Cepheid instability strip. The new geometric distance to 15 late-type detached eclipsing binaries in the SMC offers a rare opportunity to improve the foundation of the distance ladder, increasing the number of calibrating galaxies from three to four. With the SMC as the only anchor, we find H
0 = 74.1 ± 2.1 km s−1 Mpc−1. Combining these four geometric distances with our HST photometry of SMC Cepheids, we obtain H
0 = 73.17 ± 0.86 km s−1 Mpc−1. By including the SMC in the distance ladder, we also double the range where the metallicity ([Fe/H]) dependence of the Cepheid P–L relation can be calibrated, and we find γ = −0.234 ± 0.052 mag dex−1. Our local measurement of H
0 based on Cepheids and Type Ia supernovae shows a 5.8σ tension with the value inferred from the cosmic microwave background assuming a Lambda cold dark matter (ΛCDM) cosmology, reinforcing the possibility of physics beyond ΛCDM.
Trolling Shakespeare: Bad objects and the antifan discourses of Roland Emmerich's Anonymous
Authors: Pope Johnathan H. 
Published: September 2024

Roland Emmerich's film Anonymous does more than simply advance an alternative theory of the authorship of Shakespeare's plays—it actively seeks to raise the ire of Shakespeareans by depicting a buffoonish, illiterate, and greedy Shakespeare who is wholly incapable of writing the plays. And it worked: in protest of the film's release, Stratford-upon-Avon shrouded statues of Shakespeare and street signs bearing his name. This response is, perhaps, curious; in his film, Emmerich makes little effort toward rhetorical nuance or speculative accuracy based on evidentiary gaps. Instead, he prefers to launch a broadside of sensational but easily countered claims. I contend that Anonymous mobilizes various antifan discourses, primarily by trolling Shakespeare and Shakespeareans wherein eliciting anger and tail-chasing—rather than debate—is the goal. Equally important, however, is the film's disdain for fandom in general, as Elizabethan fans are depicted as overly emotional and easily manipulated by cultural producers and real artists. The result is a film that trolls those who hatewatch it, offering a mutually supportive experience wherein two oppositional forms of antifandom ultimately—and paradoxically—offer pleasure to each other.
