Published: February 2023

Background: Unique cognitive impairments related to chronic obstructive pulmonary diseases (COPD) have been increasingly reported. Considering the dementia risk and medication management, older patients with COPD should be evaluated for cognitive impairment. This study aimed to examine whether specific cognitive impairments related to COPD could be detected by an assessment tool using a touchscreen personal computer (PC) in older patients with COPD.Methods: This study included 28 older male patients with COPD and 30 healthy older male individuals. A touchscreen PC-based cognitive assessment application called CogEvo was used to assess and compare the cognitive function according to five domains: spatial cognition, orientation, working memory, executive function, and attention.Results: Analysis of variance showed an interaction effect on the indices of cognitive function based on five domains between the two groups, indicating differences in the characteristics of cognitive function in such groups. Between-group comparisons as a subtest showed that attention, executive function, and working memory were significantly lower in the COPD group than in the healthy group.Conclusion: CogEvo can detect specific cognitive impairments associated with COPD, suggesting that it can be potentially used as a screening tool for cognitive impairment in older patients with COPD.

Published: February 2023

Background & objectives:

Although several reviews of economic evaluation (EE) studies on hepatitis A virus (HAV) vaccine exist, there remains a need to corroborate such data from time to time. This study aimed to systematically review the literature for reports on EE of HAV vaccination by type of population, characteristics of intervention and income level of the country.

Methods:

PubMed and Scopus were searched to identify relevant studies from inception up to May 2021 using topic-specific key words in various combinaiton. Full EE studies comparing HAV vaccination to no vaccine or immunoglobulin were included. The risk of bias was assessed by using the ECOBIAS checklist.

Results:

Among the 1984 identified studies, 43 were found eligible. Of these, 27 were from high-income countries (HICs), 15 from middle-income countries (MICs), and one from low income country. Majority of the studies used Markov model and/or decision tree (n=26). Eight studies used a dynamic model. The discount rate, perspective and time horizon varied across the studies. Universal HAV vaccination without screening was cost-effective among children (14/16, 87.5%) and adolescents (1/5, 20%) but not in adults (0/4, 0%). Analysis by the level of income found that universal HAV vaccination among children without screening was cost-effective in 81.8 per cent of the studies conducted in MICs (9/11) as compared to 66.7 per cent in HICs (4/6). About one-third of the studies conducted among children found that screening and HAV vaccination were cost-effective compared to no vaccination.

Interpretation & conclusions:

The finding of this review suggest that universal vaccination of children without screening was likely to be cost-effective, especially in MICs. Nevertheless, it should be noted that the methodology varied across studies. Several aspects should also be considered in transferring the EE results across jurisdictions.
Dose-dependent relationship between nocturnal gastroesophageal reflux and chronic rhinosinusitis in a middle-aged population: results from the SCAPIS pilot
Authors: Bergqvist J. , Bove M. , Andersson A. , Schiöler L. , Hellgren J.
Published: February 2023

Background: Gastroesophageal reflux (GER) has been associated with several upper- and lower-airway diseases. It would be plausible if nightly occurring reflux via laryngopharyngeal reflux (LPR) might affect the upper airways. Still, the role of nocturnal gastroesophageal reflux (nGER) in chronic rhinosinusitis (CRS) is not fully established. The aim of this population-based study was to investigate the association between nGER and CRS. Methodology: This cross-sectional population-based study comprises 1,111 randomly selected subjects from Gothenburg, Sweden, aged 50-64 years. The study is based on self-reported validated questionnaires. CRS was defined according to EPOS criteria. nGER was reported in relation to frequency. Results: CRS was more common among subjects with nGER than in those without (13 vs. 4.8%). There was a dose-response association between the frequency of nGER episodes and the risk of having CRS. In the logistic regression adjusted for (age, sex, BMI, educational level, smoking, and asthma). CRS was associated with nGER, OR 1.43 and the odds ratio increased if episodes were reported “almost every night”, OR 4.6. Conclusions: The study shows an association between nocturnal GER and CRS in a middle-aged population. The revealed dose dependency supports, though does not prove causality.

This study aimed at evaluating the relative vitamins, minerals and proximate compositions of Palm kernel and Deleb palm nuts. The proximate  parameters (crude fibre, crude protein, crude fat, ash and moisture) were determined using standard analytical procedures. The minerals (Fe, Zn, Mg and  Ca) were analyzed using Atomic Absorption Spectrophotometer (ICE 3000 series) while K and Na were analyzed using Flame Photometer (model 405,  corning, U.K). The vitamins (A, B2, and D) were determined using UV spectrophotometer while vitamin C was determined using titrimetric method.  The results revealed higher percent crude fibre (12.81%), crude protein (13.13%), crude fat (44.09%), ash (3.05%), moisture (7.05%) energy (2192.33kcal/  100 g) and fatty acid contents (35.27% ) in Palm kernel nut while only carbohydrate was found to be higher in Deleb palm nut (81.71%). The  concentrations of vitamin A, B2 and D were found to be higher in Palm kernel nut while only vitamin C was found to be higher in Deleb palm nut (1.22±  0.06). The minerals composition revealed that calcium (27.79 ± 0.83 mg/100 g), magnesium (19.36 ± 1.22 mg/ 100 g), zinc (0.68± 0.12) and iron (3.35± 0.01  mg/100 g) contents in Palm kernel nut were higher than in Deleb palm nut while only the concentration of potassium (74.75 ± 0.61 mg/100 g) was found  to be higher in Deleb palm nut. However, based on the results obtained from this study, the nutritional value of palm kernel nut was found to be higher  than that of deleb palm nut and both samples could be used as good sources of some nutrients in a died.

Published: February 2023

Heavy metal contamination of soil can present dangers besides threats to humans as well as the ecosystem via uninterrupted intake or interaction with  contaminated soil and the food chain. The purpose of this research is to examine the effectiveness of calcined calcium carbide waste (CCCW) in mitigating  the leachability of lead and cadmium ions in contaminated soil from Evbareke spare parts market Benin City, Edo State Nigeria. Contaminated  soil samples were collected using quadrant sampling method at the depth of 0-15cm with soil auger. The calcium carbide waste was  obtained from a panel beating workshop dumpsite. The calcium carbide waste was dried to constant weight in an oven at 105oC. 50g of the dried  calcium carbide waste (CCW) was crushed in a mortar to obtain a powdered form. The X-ray diffraction analysis for the CCCW revealed that it was made  up of predominantly portlandite (47%), calcite fraction (23.0%), dolomite (12.7%), coesite (8.6%), muscovite (4.5%) and lime (4.0%), this was corroborated  by FTIR analysis. SEM analysis revealed that CCCW possess a rough surface with pore of varied size and irregular shape. The contaminated soil from the  Evbareke spare parts market was contaminated with petroleum hydrocarbons, the soil was saline with low C.E.C. The soil texture was loamy-sand. As the  amount of CCCW amended increase in the soil, the amount of cadmium and lead ions that was releasable in the soil reduced. The cadmium and lead ions  in contaminated soil was stabilized hence reducing the cadmium and lead availability in the soil. The optimum amender amount in the  contaminated soil to immobilize lead ion was 4% w/w and ≥2% w/w for cadmium ion. The CCCW effectively mitigated the leachability of lead and  cadmium

Published: February 2023

Nigeria is a major exporter of petroleum and natural gas and a majority of the petroleum exploratory activities takes place in the Niger Delta area, where  high rates of gas flaring associated with exploration and production of these products occur. The study investigated changes in bacterial flora and  physicochemistry of soils within the Oredo flow station facility. Seven soil samples were collected in triplicates at radial distances of 40m, 80m, 120m,  160m, 200m, 1km from the flare stack and the control sample was collected from a farmland far from the flow-station but within the community.  Standard methods were employed in evaluating the physicochemical parameters and bacteriological analysis was conducted using serial dilution and  pour plate methods. The results revealed that gas flaring had significant effects on some soil physicochemical parameters. The impact of gas flare was  found to lower the moisture content at 4.44 % for soils collected at 40m whilst for the control soil, it was 12.83%. The nitrate and total nitrogen content of  the soil varied from 9.96±1.44 to 12.21±0.13mg/kg and 0.01±0.00 to 0.2±0.01%. The total heterotrophic bacteria count varied from 0.4 ± 0.33 to  14.67±3.77 ×106 cfu/g. Identified bacterial species were; Streptococci sp., Corynebacterium sp., Stenotrophomonas sp., Staphylococcus sp., Micrococcus sp.,  Bacillus sp., Acinetobacter sp., Burkholderia sp. and Bacillus sp. The results revealed that gas flaring had a negative effect on soil bacteria population and   physicochemical properties.
The Oromo Doctrine of God
Authors: Kelbessa Workineh
Published: February 2023

The Oromo of Ethiopia, the largest ethnic group, have their own indigenous religion known as Waaqeffanna. They believe in one Waaqa guraacha (black  God) – the God who created the universe and the various forms of life. Waaqa has multiple attributes. Waaqa is He who is before everything else. Waaqa  is Uumaa (a creator of everything in the world). Waaqa is hunda beekaa (omniscient). Waaqni gonkumaa kan hin Duune (God is immortal). Waaqa is  hundaa tolaa (omnibenevolent). Waaqa is hunda danda’aa (omnipotent). Nothing is impossible with Waaqa. Waaqa is the source and lover of dhugaa  (truth). Waaqa is Qulqulluu (pure). The Oromo people believe that in the olden days Waaqa was living on the Earth and only later that Waaqa left the  Earth in anger because of personal sin and became invisible. Waaqa is one and at the same time manifests Himself in different ways. This paper teases  out and highlights core Oromo views of God, his relationship with the world and the problem of evil.

This study investigated the factors for the development of electronic library in university libraries in Southern Nigeria. The study adopted a descriptive research design with a population of 107 which comprised all the systems librarians, electronic librarians and digital librarians in the federal, state and private universities in Southern Nigeria. An online questionnaire using Google form was the main tool for data collection with a total of 107 librarians who responded appropriately. The study revealed that ICT tools, information resources and facilities were used for the development of e-library in university. The findings also showed that there was a general consensus among the respondents concerning ICT tools and resources that were used for the development of e-library such as: CD-ROM, wireless network, and interactive board, office and electrical equipment, information resources (e-book, e-journal, e-newspaper) and subscription to databases. The findings further revealed that funding, authentication, digital preservation process, copyright issues, training, and ease of access were challenges affecting the development of e-library in Nigeria. The researchers therefore recommended that universities, colleges of education and polytechnics in Nigeria should endeavor to develop its e-library by considering the findings in order to achieve its mandate of delivering quality information services to the library patrons.

Authors: Olulowo Olusegun A. , Adedokun Titilayo O. , Fawole Oluwatoyin Omoyemi
Published: February 2023

Poverty is a global social problem capable of bringing the worst behaviour out of people: Corruption, sexual decadence, bribery, diseases, educational deprivation, domestic abuse, unemployment, drug abuse and many more. The aforementioned consequences of poverty are traceable to lack of information or inability of people to access relevant information needed for sustainable development. Therefore, the church has a role to play in the development of the people as they engage in providing and disseminating information that could help alleviate poverty. This study aimed at ascertaining information sources provided by the Church, the medium of information dissemination by the church, finding out strategies/programs engaged by the Church towards alleviating poverty and to suggest strategies to improve poverty alleviation in the nation. The study adopted survey research design. The population of study was Christian churches. Pastors were the respondents of the study. Data was collected using self-developed structured questionnaire. It is believed that this study will serve as an eye-opener to some Churches and other religious bodies to see the need to engage in poverty and unemployment eradication. It would also create awareness to the Nigerian government on the impact of the Church in national development and thereby support the church for its sustainability. The study therefore recommended for the Church to take responsibility in making available physical libraries and electronic information centres where people can easily access information.

The application of fluid and heat transfer in electronic and nuclear technology is gaining popularity, particularly in equipment's life span and risk management. However, further study is required for applications involving rectangular cylinders placed inside a square cavity. This study investigates the effects of height ratio (𝐻𝑅), and width ratio (𝑊𝑅) for Prandtl number 𝑃𝑟=0.71 on natural convective heat transfer and the flow field around the annulus of a square domain fitted internally with a heated rectangular cylinder. The square enclosure and the inner rectangular cylinder walls were respectively maintained at cold and hot isothermal conditions. COMSOL Multiphysics (Version 5.6) software was adopted to implement the governing equations and boundary conditions. The results are presented in the form of streamlines, isothermal contours, and Nusselt number (Nu). The study reveals that the combined average Nu of the rectangular cylinder walls improves with 𝐻𝑅, 𝑊𝑅, and Rayleigh number (Ra). The maximum Nu occurred at 𝐻𝑅=0.7, and 𝑊𝑅=0.7; however, height variation at peak average Nu was 37.7% greater than width variation at peak average Nu. This study finds applications in the cooling of electronic chips and aerospace engines.
Comparison of Errors Caused by Flux Limiters on the Numerical Solution of Advection-Diffusion Problem
Authors: Tasri Adek
Published: February 2023

Flux limiters are widely used in numerical simulations to prevent spurious oscillation in the flow with strong property gradients. However, applying flux limiter on flow without strong property gradient such as advection-diffusion flow can cause errors. This article discusses the errors caused by several flux limiters in advection-diffusion flow solution. A method for applying one-dimensional limiters to two-dimensional unstructured mesh was also suggested. The error was measured by comparing the finite volume solution of a test case with a reference solution. The study shows that the calculation error of second-order finite volume with flux limiter was higher than that of second-order finite volume without limiter. However, the error of third-order finite volume with flux limiter is less than that of second-order without flux limiter. Among the flux limiters tested in this study, Venkatakrishnan’s flux limiter produces the highest error, followed by Van leer’s limiter, EULER and SMART limiter.

Published: February 2023

In this study, the main task is to identify the best cutting parameters to improve the machining performance during MQL-turning with various cutting fluids like coconut oil, ground nut oil, sunflower oil, soyabean oil, and blassocut oil. Cutting temperature and surface roughness were used as performance metrics, with the goal of minimizing these responses. To construct an experimental plan for turning AISI4130 with uncoated brazed carbide, full factorial design for three levels and three factors (33) design of experiments was used. The optimalcutting parameter was identified using the response surface approach. Aiming to discover the optimum possible cutting settings, the desirability function method was utilized. It was discovered that the best cutting speed, depth of cut, and feed rate for minimizing the temperature and surface roughness are 72.38 m/min, 0.5 mm, and 0.35 mm/rev respectively. According to the ANOVA findings, the feed and depth of cut have a substantial impact on the tool temperature for MQL-soyabean oil.

Epie creek, located at the Southern part of Nigeria has been known for its use as sink for the disposal of untreated sewage and industrial effluents. Benthic foraminifera are increasingly been used as environmental bio-indicators of pollution. Their munity structure provides information on the general characteristics of the environment and some species are sensitive to specific environmental parameters. This study investigates recent foraminifera from sediment samples collected from ten (10) stations (ranging in depths from 1m to 4.2m) in the Epie creek from Igbogene to Tombia- Etegwe. The environmental factors that necessitate their existence such as temperature, pH, salinity and dissolved oxygen were measured during the sampling time. Metals were determined using atomic absorption spectrophotometer. Recognized benthic foraminifera species belonging to four (4) genera of three (3) families and four(4) suborder were identified. Five (5) benthic foraminifera taxa were identified from sediment samples which include Lenticulina stellata, Saccammina sp, Marginulina costata, Marginulina cf. planata and Trochammina sp. The stress tolerant specie, Trochammina ,sp. was common in the study area confirming a stressed environment.

Wartime leadership in the context of organizational change theories
Authors: Batryn Natalia
Published: February 2023

After the beginning of the wide-scale terrorist invasion of Ukraine on February 24, 2022, leadership theorists shifted their research focus to wartime leadership.  The aggressor demonstrated extreme cruelty in fighting with the peaceful people of the country and in one day millions of peaceful leaders changed into wartime leaders. Despite the plethora of research studies devoted to leadership theories, the research topic of wartime leadership has not been discussed widely. The article aims to explore the effective wartime leadership styles, skills, and attributes that can be applied during the war and investigate practical change theories that can help wartime leaders achieve the organizational goal of survival. The author used a phenomenological design because this study attempts to understand students’ perceptions relative to a particular situation. Nine students of West Ukrainian National University were interviewed and shared their perceptions of the practical wartime leadership skills and change theories that can be applied during the war period. The sample size is aligned with a typically used for phenomenological research sample size from 5 to 25 individuals. Literature analysis and research findings show that there is no best leadership style that proves to be the most effective during the war. However, the list of practical wartime leadership skills differs from peacetime leadership skills and embraces such personality attributes as courage, integrity, honesty, reliability, and responsibility. Besides, wartime leadership is about strong communicative skills, fast decision-making, and positive affectivity. Moreover, it is about the constructive implementation of new changes. Therefore, change theories can help wartime leaders to face the challenges. The change theories should be simple, flexible, and easy to be modified.
Submarine landslide and associated polygonal faults development: a case study from offshore Norway
Authors: Le Anh Ngoc , Bui Ngan Thi ,   Hanoi University of Mining and Geology, Hanoi, Vietnam
Published: February 2023

Submarine slide and polygonal faults have been investigated using high-resolution 3D seismic data, over an area of 2,300 km2. The study area is located on the continental slope, offshore Norway. Submarine sliding covers more than half of the study area, and is part of the Storage slide. The slide developed a series of extensional faults at the upper extensional zone which is gradually changed to chaos seismic facies, interpreted as mass transport deposits. There is no clear evidence of compression/contractional zone downslope. Polygonal faults are highly developed in the KS1 and KS2 interval, corresponding to the Lower Miocene age. The fault has small offset of c. 10÷30 ms TWT, spacing ranges between c. 500 m and 1 km. Within this faulted interval, faults tend to develop intensively below the submarine sliding and much less out of that area. Bright amplitude anomalies are observed within the north south – elongated anticline structure. It has been mapped over an area of c. 135 km2 coinciding with the top anticline. Among those, there are two obvious negatives, bright amplitude reflectors which are relatively flat at 2670 ms TWT (flat spot 1) and 2800 ms TWT (flat spot 2). These flat spots are interpreted as hydrocarbon-brine contacts. Flat spot 2 is bounded by the structure contour but there is no evidence for the unconformable with the lithologic reflections from the trap boundary, thus this still needs to be confirmed by well data. Bright amplitude anomalies suggest the existence of hydrocarbon in the trap, in addition, the occurrence of polygonal faults is linked to seal potential covering the underneath petroleum reservoir, proving the great hydrocarbon potential in this area.

Published: February 2023

An Chau trough with an area of ​​​​about 10,000 km2 located in the Northeast of Vietnam is the southwest tail of the Mesozoic Thap Van Dai Son basin and has a complex geological structure. The geological structure of An Chau trough has been studied since the 70s of the last century, however, previous studies were mainly surface geological studies. Deep structure studies only based on measurement gravity data at the scale of 1/200.000 with outdated machinery, equipment and processing technology. With the goal of re-searching, investigating and surveying oil and gas resources, from 2013 to 2017, Vietnam National Oil and Gas Group has deployed measuring over 9,000 km of the Airbone high-resolution Mag-Gravity survey with the resolution of measuring points on the measure-line from 6 m to 7 m/point, more than 450 ground gravimetric points and acquiring over 1,000 km 2D seismic survey. All magnetic-gravity and seismic data collected in the field is then processed at processing centers with modern technology such as Sander Geophysics - Canada, Institute of Geophysics - VAST, CGG Veritas Singapore.

Objectives: The study aimed to determine the levels of change of the markers related to radiographic progression, such as Dickkopf-1 (DKK-1), sclerostin (SOST), bone morphogenetic protein (BMP)-2 and -4, and interleukin (IL)-17 and -23, in ankylosing spondyloarthritis (AS) during anti-tumor necrosis factor alpha (TNF-α) treatment.

Patients and methods: Fifty-three anti-TNF-α naïve AS patients (34 males, 19 females; median: 38 years; range, 20 to 52 years) refractory to conventional treatments meeting the modified New York criteria or Assessment of SpondyloArthritis International Society classification criteria were enrolled to this cross-sectional, controlled study between October 2015 and January 2017. Fifty healthy volunteers (35 males, 15 females; median: 36 years; range, 18 to 55 years) with similar age and sex characteristics were recruited. Serum DKK-1, BMP-2, BMP-4, SOST, IL-17, and IL-23 levels were measured in both groups. The serum levels of the markers were measured again after about two years (mean follow-up duration of 21.7±6.4 months) in AS patients who started anti-TNF-α treatment. Demographic, clinical characteristics, and laboratory parameters were recorded. The disease activity at the time of inclusion was assessed through the Bath Ankylosing Spondylitis Disease Activity Index.

Results: Serum DKK-1, SOST, IL-17, and IL-23 levels in the AS group before anti-TNF-a treatment were significantly higher compared to the control group (p<0.01 for DKK-1, p<0.001 for others). There was no difference regarding serum BMP-4 levels, whereas BMP-2 levels were significantly higher in the control group (p<0.01). Forty (75.47%) AS patients had serum marker levels measured after anti-TNF-α treatment. No significant change was observed in the serum levels of these 40 patients measured 21.7±6.4 months after the initiation of anti-TNF-α treatment (p>0.05 for all).

Conclusion: In AS patients, there was no change in DKK-1/SOST, BMP, and IL-17/23 cascade with anti-TNF-α treatment. This finding may suggest that these pathways act independently of each other, and their local effects are not influenced by systemic inflammation.

Landslide investigation in Laeya Village of North Buton Regency, Indonesia, is necessary since this area is frequently experiencing landslides. In this study, we applied a joint analysis of interferometric synthetic aperture radar (InSAR), electrical resistivity tomography (ERT), and in-situ geology observation. The objectives of this multidisciplinary study are: a) to estimate ground deformation through the InSAR method, b) estimation of subsurface characteristics based on the electrical resistivity of rocks, as well as estimation of the shape of the slip plane and the type of landslide that resulted; and c) to identify the surface geology conditions of the site from an in-situ geology survey. The InSAR data of the Sentinel-1A acquired from 2015 to 2017 were processed using the Sentinel toolbox. The resistivity data collected utilizing the electrodes array of the Wenner-Schlumberger configuration were processed employing the RES2DINV. The in-situ geology survey involving the observation of elevation, slope, and soil and rock type was also carried out in the landslide area. The InSAR method may estimate the deformation of slope material of the investigated sites with a magnitude ranging from -53 mm to +55 mm. The negative mark of the magnitude means that the ground deformation is ground subsidence and the positive means ground uplift. The ERT method has successfully estimated the existence of the saturated zones, the clay layer that acts as a slip plane, and the slip surface type. There are at least two types of slip planes estimated, namely the planar and uneven curvature slip planes that generate the translational and the complex landslides, respectively. In-situ observations of geological conditions support the results obtained from the InSAR and ERT methods.

Published: February 2023

Searching one of the most important reservoirs of the Cretaceous in Iraq is the aim of many researchers. The studied sequences are in the Mishrif Formation in southern Iraq. The goal is to define fauna and design biostratigraphic zoning. Forty genus and species were identified as associated with the most capable reservoir facies (the biostrome). Identification of biostrome facies mainly was in the Late Cenomanian part of the studying sequences. Suggested biozones are based on eight biomarkers, two of which appear and disappear together, leading to four interval biozones. They are; (1) Nezzazata simplex and Nezzazata conica concurrent biozone delineating the Middle Cenomanian age. (2) Praealveoilina cretacea and Pseudorhapydionian concurrent biozone. (3) Praealveolina tenuis and Cisalveolina lehneri concurrent biozone. (4) Chrysalidina gradate and Pseudolituonella reicheli concurrent biozone delineating the Late Cenomanian.

Authors: Bamerni Kaheen , Mohammad Rashied
Published: February 2023

The impacts of leachate on the soil count as one of the main environmental issues, especially near waste dump areas. The Kwashe dumpsite is located in the Semel district, west of Duhok City. Different types of waste had accumulated from medical, construction, and household materials without any barrier or control of the contamination. Wastewater flows on the surface and percolates downward all over the area. Geophysical methods provide high-resolution data to investigate subsurface environmental conditions with no disturbance in the materials. In this study, the 2D resistivity technique by Ohm-Mapper device (G-858G) with a dipole-dipole arrangement was utilized along six resistivity profiles. the system uses one Transmitter to couple an active current signal to the ground and the voltage difference is recorded by one Receiver with separation distances of 2.5, 5.0, 10.0, and 15.0 m. The resistivity data from MagMapper software was transferred to Res2dinvx32 software to create an inversion model for the subsurface. The results showed two main parts: The upper part consists of soil material mixed with recent deposits and fill materials formed of alluvium deposits with resistivity values of 15-50 Ohm.m at a depth between 0.25-3.0 m. The bottom section represents leachate of bowl-shaped anomalies of very low resistivity values of less than 1.0 Ohm.m at various depths. The type of materials in the left and right edges of each of the models represent the main weak zone for leachate infiltration.

Authors: Awad Eman , Al-Haddad Khaled
Published: February 2023

In this paper, limestone quarries in the Bazian region, west of Sulaymaniyah city, northern Iraq, were evaluated geotechnically to examine their suitability for developing asphalt concrete for the top layer of roadways. Two samples were collected to perform geotechnical testing, including physical, chemical, and permanence tests. From the physical results, it is evident that the coarse and fine aggregate grain sizes demonstrated conformity to the American Society for Testing and Materials ASTM-C136 as well as the requirements of the fine aggregate standards ASTM-C117, which fall within the coarse, fine, and filler areas. Moreover, the findings revealed that the flat granules are 22% and the longitudinal granules are 35%. Based on these results, it did not go over the limits set by British standards, so it meets the requirements for concrete work. Another promising finding of durability tests was 21.8%, which represented the highest weight loss. This is an important finding in the understanding of the suitability of the aggregate to American and Iraqi standards in concrete work. A further novel finding of stability tests demonstrated the cement's suitability with Iraqi standards and the American standard C131-C535-2003. Finally, the results of Marshall's test for density, creep, and stability reveals the conformity with the Iraqi specification for asphalt concrete works D2726-05, where the density value was 2.292 and the percentages of creep and stability were 12.2 kN and 2.9 mm, respectively. The results of examining the cement asphalt were in accordance with the specifications required for concrete works, where the optimum percentage of asphalt for the design of the asphalt mixture for the surface layer was 4.8. Also, the percentage of airspace was 4.1 according to the American standard D2041.

This study intends to describe the form and historical portrayal of the student movement during the reform era in Laut Bercerita by Leila S. Chudori. This is an interpretive qualitative study employing the knife analysis of new historicism. The New Historicism approach is used to analyze Leila S. Chudori's novel Laut Bercerita which integrates non-literary texts into the literary texts to be analyzed. The results of the study identified four student movements depicted in the novel Laut Bercerita during the reform era: (a) discussion of the "margin kiri" book, which was considered an attempt by students to overthrow the government, (b) rejection of the dual function of ABRI, (c) the Blangguan incident as an act of rebellion students to defend corn farmers whose land will be confiscated, and (d) the Kamisan Action, which was carried out by the families of those who had been coerced into disappearances while they were all dressed in black and gathered in front of the State Palace in an attempt to uncover the truth about human rights violations. These events are reflected in the story through the experiences of the characters. The novel contextualizes actual historical events. According to New Historicism, socio-political historical events are presented to call into doubt previously recorded historical truths. It is expected that the results of the New Historicism study on Leila S. Chudori's novel Laut Bercerita will help individuals comprehend Indonesian history and allow them to learn from terrible historical occurrences so that they won't be repeated in the future.
