Authors: Raharjo Dwi Sihono
Published: May 2023

This research undertakes an in-depth analysis to examine the correlation between Price to Book Value, Price Earning Ratio, and asset growth on stock prices. Return On Equity was used as a moderating variable in scrutinizing LQ45 companies registered on the Indonesia Stock Exchange. The study targeted companies featured in the LQ45 list on the Indonesia Stock Exchange during 2019 - 2022. A purposive sampling method was employed to select a representative sample of 26 companies for the regression analysis, which was conducted using a multiple linear model. The results indicated that Price to Book Value, Price Earning Ratio, and asset growth collectively had a significant impact on stock prices. However, individually, Price to Book Value and asset growth demonstrated a notable effect on stock prices. Residual test analyses were also carried out to validate the results. The impact of the price earning ratio on stock prices is negligible. However, it's worth noting that the profitability variable can act as a moderating variable, either amplifying or diminishing the influence of independent variables on stock prices.

Authors: Ramadhan Al-Hadithi Areen T. , Abdulmajeed Ban A. , Abdulrasool Shareef Hula R.
Published: May 2023

Background: Dystrophinopathies are the commonest forms of muscular dystrophy and comprise clinically recognized forms, Duchenne Muscular Dystrophy (DMD), and Becker Muscular Dystrophy (BMD). Mutations in the dystrophin gene which consist of large gene deletions (65%), duplications (5%) and point mutations (30%) are responsible for reducing the amount of functional dystrophin protein in skeletal muscle fibers.  This study concentrate mainly at the spectrum of deletions in the 'distal hot spot' region of the DMD/BMD gene in Iraqi DMD/BMD patients using multiplex PCR technique
Objectives: The aim of this study was to investigate the rate, and distribution of deletions in 10 exons of Dystrophin gene in a group of Iraqi dystrophinopathy patients using the multiplex polymerase chain reaction (MPCR).
Patients materials and methods: This is a case prospective study which include 27 clinically diagnosed DMD/BMD patients and six suspected carriers in Medical city /Baghdad . A written consent was obtained from each family for going the research as well as ethical committee approval. Forty six apparently healthy individual were included as a control group. Blood samples were collected in 5-6 ml EDTA tubes by venepuncture. The DNA was extracted by using the Wizard Genomic purification kit (Promega/USA), and the quantity was estimated by UV-spectrophotometer (Cecil CE7800) . Ten exons of the dystrophin gene were examined ( 19 ,45 ,46 ,47 ,48 ,49 ,50 ,51 ,52,53)   using synthesized primers with complementary sequences and set in five different multiplex PCR groups. The products of PCR amplifications were subjected to electrophoresis and visualized by The UVCI140 & 200 series (advanced CCD gel imaging system from Major Science. It consists of a CCD camera, UV transilluminator UV- light system). All done in college of medicine /Baghdad university.
Results: The rate (relative frequency) of subjects with any positive exonal deletion (among the10 selected and tested exons was significantly higher (85.2%) among patients compared to that among the suspected carriers (33.3%).The distribution of exonal deletions among patients compared to suspected carriers were statistically significant. The frequency of deletions detected in male patients (~82%) was higher than frequencies mentioned in the other studies of comparison. The control group show no deletion in all tested exons.
Conclusions: Multiplex PCR technology was utilized to demonstrate the frequency of 10 exons deletions in a limited group of Iraqi DMD/BMD patients. The overall distribution of deletion mutations in the distal ‘hot spot’ region was higher than that of DMD/BMD cases investigated elsewhere. The study also serves as a good starting point for further investigations into the genetic aspects of the Iraqi DMD/BMD population.

Published: May 2023

Background: Polycystic ovary syndrome (PCOS) is one of the most common female endocrine disorders leading to infertility. Majority of women with PCOS have insulin resistance and elevated hemoglobin A1c.The presence of thyroid dysfunction may affect the levels of HbA1c and the results of ovulation induction programs.                                                                                                           
Objectives: To evaluate the level of serum hemoglobin A1c according to the type of thyroid dysfunction in polycystic ovary patients during ovarian stimulation trials.                  
Patients and Methods: Eighty three polycystic ovary patients were enrolled in this study, attending the infertility clinic in Al-Yarmouk Teaching Hospital, in the period between November 2012 and May 2013. After thorough history and examination blood samples were withdrawn for the estimation of LH, FSH, testosterone, prolactin, TSH, T3, T4 and A1C in day 2 or 3 of the menstrual cycle, Progesterone was determined in day 21 of the cycle. Ultrasound was done also at cycle day 3 for antral follicles measurements. After diagnosing PCOS the patients were divided into 3 groups, euthyroid group (control), hypothyroid and hyperthyroid groups. Ovulation induction treatment was given and ultrasound was done at the day of hCG injection.                                          
Results: There was no significant difference between control and patients groups regarding age (26.31 ± 5.04 Vs 27.17 ± 5.76) and BMI (31.7 ± 5.69Vs 29.25 ± 6.28).HbA1c level was significantly different between the control and patients group with a significant positive correlation between HbA1c and TSH. In clomiphene citrate treated groups, Hb A1c level, the number of antral follicles and the size of follicles at day of hCG injection were not significantly different between the patients and control groups.                                                                                                                                
Conclusions: HbA1c level is significantly affected by thyroid dysfunction in PCOS patients as it is higher in the Hypothyroid group and lower in the Hyperthyroid group. Using Clomiphene citrate in PCOS does not significantly increase the mean size of follicles after ovarian stimulation in patients with thyroid dysfunction from that in Euthyroid ones.

Anaerobic Digestion for Biomethane Production from Food Waste Pretreated by Enzymatic Hydrolysis
Authors: Deb Nibedita , Alam Md. Zahangir , Rahman, et. al. Tawfkur
Published: May 2023

Food waste (FW) is one of the main problems in the world due to the continuous increase in the global population. Anaerobic digestion (AD) of FW was an alternative and economical solution to develop an effective method to enhance biomethane (BioM) production that uses enzyme pretreatment and hydrolysis of FW by locally produced cellulase and amylase enzymes. In this study, two types of sources fungi (TNAF-1 to TNFA-3) and (TNBC-1 to TNBC-3) strains were isolated from animal feed and compost. The cellulase and amylase activities were 300U/mL & 400U/mL, respectively. Based on OFAT results obtained, optimization of three factors such as pH of 5, TS of 12.5% (V/V) and enzyme loading of 80U/mL was carried out by applying the FCCCD under the RSM to develop a second-order regression model successful improvement in the production of reducing sugar of 162mg/mL was achieved. However, biogas yield was optimum using OFAT parameters such as the biogas inoculum of 25%, pH of 7, AD digestion times of 29 days, 500mL of hydrolysate food waste and room temperature at 30°C (±2). The results show the biogas contained was found such %3 hydrogens, 57% methane and 40% carbon dioxide. The new fungi are very potential for upgrading the biogas of BioM that is non-toxic as well as biodegradable, and therefore may be encouraging to the water treatment plants in future applications.

A Pragmatic Study of Topoi in Trump's Tweets
Authors: Al-Mamoory Salih Mahdi Adai , Abbass Abdul-Ameer
Published: May 2023

Standard arguments that usually draw on the premises, which are taken for granted and adequate to accept the end, are called topoi. This strategy is closely associated with the process of rejecting immigration by American politicians. American politicians use the strategy of topoi extensively to criticize each other on the one hand and to convince public opinion and the audience of their opinions on the other hand. In particular, former US President Donald Trump employed the strategy of topoi in an unconventional and intense manner, in various ways and methods, in order to disparage, criticize, and attack his political opponents for the purposes of winning the vote in the US presidential elections. He focused his attention on the issue of immigration and the immigrants, and the negatives resulting from the mismanagement of the immigration file by his political opponents, as he made it a pretext to overthrow the opponents. To achieve this, one time, he uses speech acts; another time, he uses the implicature and another time, he uses figures of speech. All these employments are under the general name of pragmatics. In this consideration, the study tries to shed light on this strategy employed by Trump by exploring the implicit motivations behind employing it. For this purpose, the study develops an eclectic model that integrates two approaches. The first one is Searle (1979), on which the study relies on the pragmatic analysis, and the second is Reisigl and Wadak (2001), on which the study relies on the analysis of topoi as a discursive strategy.

INFLUENCE OF ENGINEERING PROPERTIES OF SOILAND GROUNDWATER MOVEMENT ON GULLY DEVELOPMENT IN RAFINGORA, NORTHERN BIDA BASIN, NIGERIA
Authors: Omeiza Muhammed Nurudeen , Idris-Nda Abdullahi , Waziri Salome Hephziba , Waziri Nuhu
Published: May 2023

The formation and expansion of gullies in Rafingora community, northern sector of the Bida Basin, Nigeria was investigated. This was aimed at determining the controlling factors for gully development in the area, using field gully parameter measurements, hydrogeological mapping and geotechnical investigation of soils from gully sites. U-shaped gullies were mapped with sliding, slumping and block fracturing as the main modes of gully propagation. Relief is gentle; slope angles range from 1.58° to 1.96°, indicating little or no influence of elevation on gully development. Gullies were found to be deeper than 3m, with drainage area of more than 30m. Depth to water in open wells ranges from 5.5m in the north-eastern part to about 16.4m in the south-western part. Gullies in the north-eastern side are mostly shallower than the water table, contrary to the situation in the south-western part. This shows a direct relationship between water table elevation and gully propagation and is further exacerbated by the relatively high average hydraulic of soils.  The soils have low plasticity, cohesion, angle of internal friction (AIR) and maximum dry density (MDD). A combination of these poor geotechnical properties makes the soils friable and crumbles easily when in contact with water and offers very little resistance to erosion. Conclusively, gully development in Rafingora is influenced more by bottom erosion due to high hydraulic conductivity and seepage forces, rather than by overland runoff. Reclamation attempts may consider lowering groundwater levels as a major strategy for erosion control in the area.

Enhancement of Near-Field Radiative Heat Transfer based on High-Entropy Alloys
Authors: DENG Shanshan , SONG Ping , ZHANG Boxi , YAO Sen , JIN Zhixin , GUO Defeng
Published: May 2023

The enhancement of near-field radiative heat transfer (NFRHT) has now become one of the research hotspots in the fields of thermal management and imaging due to its ability to improve the performance of near-field thermoelectric devices and near-field imaging systems.  In this paper, we design three structures (multilayer structure, nanoporous structure, and nanorod structure) based on high-entropy alloys to realize the enhancement of NFRHT. By combining stochastic electrodynamics and Maxwell-Garnett's description of the effective medium, we calculate the radiative heat transfer under different parameters and find that the nanoporous structure has the largest enhancement effect on NFRHT. The near-field heat transfer factor (q) of this structure (q = 1.40×109 W/ (m2•K)) is three times higher than that of the plane structure (q = 4.6×108 W/ (m2•K)), and about two orders of magnitude higher than that of the SiO2 plate. This result provides a fresh idea for the enhancement of NFRHT and will promote the application of high-entropy alloy materials in near-field heat radiation.

Published: May 2023

Undercooling of ternary CoCrNi medium entropy alloy (MEA) was achieved by molten glass fluxing method. The influence of undercooling on microstructure and mechanical properties of was investigated. The microstructure changes during the undercooling process identified by transmission electron microscope and scanning electron microscope shows that the grain size and intergranular phase all change after the undercooling treatment. The yield strength of the ternary MEA increased significantly after undercooling treatment, which attribute to the refined grain size and the formation of the new phase. Undercooling method can be used as a potential method to modify the microstructure and improve the mechanical properties of MEAs.

High saturation magnetization and low coercivity are required for soft magnetic materials. This study investigated the Co47.5Fe28.5Ni19Si3.3Al1.7 high-entropy soft magnetic skeleton was prepared by selective laser melting. Then Al was pressure infiltrated into skeletons to obtain a dense composite material. The high-entropy composite materials possessed favorable compressive ductility and moderate soft magnetic properties. The high-entropy composite materials were obtained with Ms being 97.1 emu/g, 79.8 emu/g, 33 emu/g and possessing 19 Oe, 15.8Oe and 17Oe of Hc, respectively. However, the magnetostriction coefficient remains low level, about 5ppm. These reported properties are attributed to the special structure of the material studied in present experiment. Nevertheless, a novel strategy of structural designing was proposed in this paper.

The present work investigates the effect of Ni on the microstructure, mechanical properties, and corrosion resistance of CoCrFeNixAl0.15Ti0.1 high-entropy alloys. It was found that the appropriate addition of Ni element in the alloy is beneficial to reduce the average grain size of the alloy. The yield strength and tensile strength of the alloy under fine-grain strengthening have also been increased, while the ductility of the system in this study has not been significantly affected. In terms of corrosion resistance, CoCrFeNixAl0.15Ti0.1 high-entropy alloys form a dense passive film at open circuit potential, possessing good corrosion resistance. However, with the excessive addition of Ni content in the alloy, the pitting corrosion resistance of the alloy in the environment of chloride ions will decrease due to the relative decrease of the relative content of Cr element. This work also can provide guidances for the design and development of new precipitation-strengthened CoCrFeNi-based high-entropy alloys with excellent comprehensive properties.

The diagnosis of germline predisposition to myeloid neoplasms (MN) secondary to DDX41 variants is currently hindered by the long latency period, variable family histories and the frequent occurrence of DDX41 variants of uncertain significance (VUS). We reviewed 4,524 consecutive patients who underwent targeted sequencing for suspected or known MN and analyzed the clinical impact and relevance of DDX41VUS in comparison to DDX41path variants. Among 107 patients (44 [0.9%] DDX41path and 63 DDX41VUS [1.4%; 11 patients with both DDX41path and DDX41VUS]), we identified 17 unique DDX41path and 45 DDX41VUS variants: 24 (23%) and 77 (72%) patients had proven and presumed germline DDX41 variants, respectively. The median age was similar between DDX41path and DDX41VUS (66 vs. 62 years; P=0.41). The median variant allele frequency (VAF) (47% vs. 48%; P=0.62), frequency of somatic myeloid co-mutations (34% vs 25%; P= 0.28), cytogenetic abnormalities (16% vs. 12%; P=>0.99) and family history of hematological malignancies (20% vs. 33%; P=0.59) were comparable between the two groups. Time to treatment in months (1.53 vs. 0.3; P=0.16) and proportion of patients progressing to acute myeloid leukemia (14% vs. 11%; P=0.68), were similar. The median overall survival in patients with high-risk myelodysplastic syndrome/acute myloid leukemia was 63.4 and 55.7 months in the context of DDX41path and DDX41VUS, respectively (P=0.93). Comparable molecular profiles and clinical outcomes among DDX41path and DDX41VUS patients highlights the need for a comprehensive DDX41 variant interrogation/classification system, to improve surveillance and management strategies in patients and families with germline DDX41 predisposition syndromes.

Published: May 2023

Biomass briquette stove is a cooking tool that is still widely used by the people of the interior of South Sulawesi. Even in urban areas, it is not uncommon to find their use because of the ease of obtaining briquettes and its relatively good efficiency. This study aims to determine the best performance of a biomass stove from three types of clay material stove shapes in different configurations of geothermal variations. The three variations of the geometric shape of the stove are cylindrical, rectangular and hexagonal using biomass material from coconut shell charcoal in the shape of a honeycomb with an inner diameter of 15 mm and an outer diameter of 65 mm and a height of 45 mm. The uniqueness of this stove is the addition of a sleeve diameter of 180mm in the stove's combustion chamber as heat insulation so that the combustion process in the combustion chamber can be more perfect. The test results show that the presence of a flat surface on the stove wall will accelerate heat loss compared to the cylindrical surface. This is in line with the results which show that the highest rate of heat loss occurs in a rectangular shape, then a six-square shape, and the last is a cylindrical shape. Furthermore, it can be concluded that the cylindrical stove is the superior of the two in terms of flame temperature, ability to boil water and thermal efficiency of 798°C, 30 liters and 73.66%, respectively.

The RCM is integrated with Failure Mode Effect Analysis (FMEA) for analyzing The Highest Risk Priority Number (RPN). The research results that the optimal maintenance time of the Prebreaker Machine is 51 hours which means the Prebreaker Machine is maintained after operation for 51 hours.
The Ethical Mystery of the Sphinx Riddle
Authors: JIN Xusheng
Published: May 2023

This thesis embarks upon a polemic trek by poring over the origin of human ethical consciousness in Adam and Eve after their eating of the Tree of Good and Evil in the Bible, then goes on to explore the ethical mystery of the Sphinx Riddle in Greek Mythology, illustrate the ethical dilemma of Hamlet in Shakespeare’s renowned drama, and finally wind up with a new vision on Robert Frost’s poem with Lawrence’s idea of the Noble Wild Beast. Believing that there has appeared the binary of animality and rationality in man since the Biblical time, this thesis believes that human beings have repeatedly prized rationality over animality, emphasized ethical order over native desire, thus adoring knowledge and power while despising emotion and love. It tries to explore into such questions as: Why does God forbid Adam and Eve from plucking from the Tree of the Knowledge of Good and Evil? Is Eve making a sort of ethical choice by eating the Forbidden Fruit? What is the ethical significance of Sphinx itself?
Understanding Conservatism in Turkish Society in the Light of Pierre Bourdieu’s ’Habitus’
Authors: Karakurt Mustafa
Published: May 2023

With the social effects of liberal policies and being integrated into the capitalist system, particularly after the 1980s, Turkish society has experienced a change both culturally and structurally. This transformation has paved the way for orientation to religion, tradition, and conservatism among the working class and the capital class owners. Therefore, the conservative wing that tries to associate religious values with consumer values and enables the emergence of a hybrid eclectic culture began to create a lifestyle for themselves with the impact of consumer society values.

On the Identity of Problem Domain
Authors: Tao Yingchun
Published: May 2023

By analyzing some thoughts and viewpoints of scientific philosophers such as Popper, Lakatos, Kuhn, and Laudan, this paper thinks that abstract theory and concrete theory constitute the problem domain. Abstract theory evaluates the legitimacy of the problem, and concrete theory evaluates the difficulty degree of the problem. The comparison of the legal degree of the problem and the difficulty of the problem is only possible in the same problem domain. Popper believes that the problem domain is the same in practice. Lakatos, Kuhn, and Laudan do not fully agree with Popper’s views and give their solutions. Laudan’s scheme is relatively reasonable.

Larry Laudan’s View of Scientific Progress
Authors: Jing Xiaoqin
Published: May 2023

The problem of scientific truth has always been a crucial problem in the philosophy of science. The previous schools of logical empiricism and falsificationism believed that science and truth contained each other. But historicists, such as Thomas Samuel Kuhn, Paul Feyerabend, etc., believe that truth and science have nothing to do with each other, and the two are completely separate. Larry Laudan also believed that science has nothing to do with truth, but he tried to find a middle way between logicism and historicism.
