USING FILLET WELDS INSTEAD OF CJP GROOVE WELDS IN DIRECTLY-WELDED FLANGE FR MOMENT CONNECTIONS
Authors: A.Uraiyer Faris
Published: June 2023

The possibility to use fillet welds instead of complete joint penetration welds (CJP ) in directly- welded flange FR (fully restrained) connections is the main aim of this study. An experimental comparison has been made between these two types of welds. Fifteen specimens have been configured by welding plates to form butt, Tee and lap joint connections; three specimens with butt-joint, six with lap-joint, and six specimens were with T-joint. Fillet and CJP groove welds separately have been used to make these connections. After testing of all these specimens, the results indicated that the appropriately sized fillet weld is a good alternative to CJP groove weld when it is used for fully restrained FR moment connections.

Authors: Al-Thabhawee Hayder Wafi
Published: June 2023

Nowadays, use of castellated steel beams (CSBs) has become very common because of their advantageous implementations in construction of buildings. Castellated Steel Beams (CSBs) are those members that are fabricated from standard hot rolled steel (HRS) I- sections by cutting along its web in "zigzag" pattern and thereafter rejoining the two halves on one another by welding together to form a castellated beam, so that generally the depth of Â a section will be increased. This research analyses the experimental results of six specimens of castellated steel beams and compares with control beam (Parent section). The purpose of this study is to investigate the effect of hexagonal hole dimensions on the ultimate strength and stiffens response of the castellated steel beam. Also, the effect of number of holes on the behavior of the castellated steel beams that have the same span and ratio of expansion was investigated. All specimens of the castellated steel beam were fabricated from hot rolled steel section (IPE140) and were expanded to (1.56) times the parent section depth. From the test results, it is observed that best dimension of castellated steel beam was (span length to holes space ratio L/S = 8.0); hole depth to Castellated beam depth ratio is h/H=0.56, and hole space to the castellated beam depth ratio is S/H = 1.03. The ultimate strength of the castellated steel beam was increased about (50%) stronger than the original beam.

Authors: Akesh Ammar Ashour
Published: June 2023

Concentration of 2 heavy metals; lead and mercury (Pb and Hg) in rivers and sediments soil were studied at different sites in Basrah. In this study, the effect of lead and mercury pollutions is studied together with determining their locations in the surface water and sediments at some areas in the South of Iraq (Basrah Governorate) particularly in the upper areas of the Arabian Gulf and in its northern part. These seven locations are: Qurnah, Madinah, Deir, Ashar, Abo Alâ€“Khasib, Zubair and Um Qasir. The effect of the lead and mercury concentration on surface water and sediments analysed during 2014-2015 quarterly. Standardized method have been followed in analysing and comparison the surface water standards and sediment soil just to determine the percentage of lead and mercury pollution and assesse the values with standard pollution index. Overall concentrations of Pb in the rivers ranged from 0.44-4.5 mg/l for surface water and soil sediment samples ranged from 0.0-7.36 mg/kg, and for Hg in the rivers from 0.0003-0.006 mg/l and soil sediment samples ranged from 0.0005-0.009 mg/kg. The concentration of heavy metals in the surface water and soil display the following decreasing trend: Pb>Hg. From this result, found that levels of heavy metal in surface water and soil near industrial areas give higher value compared with other locations in Basrah. The Pollution index revealed that Pb and Hg give low contamination. The highest concentrations values are recorded in Abo Al-Khasib (7.63 ppm) for the underground sediments, the lowest concentrations values are recorded in Madina for the depth sediments. The highest concentrations are recorded in Al-Deer (0.009 ppm) for the mercury pollution. Results of combined heavy metal concentration and heavy metal assessment indicate that industrial activities and traffic emission represent most important sources for Hg and Pb. The pollution Index were calculated for the two pollutants concentrations at the rivers and soils.
LIMITS OF CAPACITY INCREASE IN CELLULAR NETWORKS DUE TO THE IMPLEMENTATION OF DEVICE TO DEVICE COMMUNICATIONS
Authors: Rahi Kareem Dhahir
Published: June 2023

(D2D) Device to Device communications is a new approach which proposes the separation of data planes and control, thus revolutionizing the traditional methods of communication. This approach is capable of increasing the capacity of the system significantly by providing three types of gain: proximity gain, hop gain and reuse gain, thus it is considered as an approach for the next generation of cellular networks. However, this type of communications can cause interference within the cellular network if not properly designed. To investigate the possible increase in the system capacity and reduce the effect of interference, a three-step algorithm was proposed and evaluated against three matrices: throughput gain, user capacity and access rate. Â The simulation results showed that as the D2D pair gets closer to each other the access rate increases and it can reach up to 98%. Also the throughput gain is directly effected by the distance between the D2D pair as it can reach up to 100% when placing the D2D at an area of 100 m2 and decreases gradually when increasing the distance, while placing the D2D pair at the edge of the cell will result in higher throughput gain as it can reach up to 130% at D2D to CU ratio equals to 1. Finally, the simulation results proved that it is possible to add an extra 60% of the already existed users when using the D2D communication within the cell.

Aim: Although several patients with kidney disease have simultaneous dysfunction of the parasympathetic and sympathetic nervous systems, orthostatic hypotension during a hemodialysis (HD) procedure impacts not only the form of treatment but overall comfort of life for patients with HD. Despite a number of methods that are not invasive and have already been used to assess autonomous functioning, a system for monitoring malfunction throughout filtration of blood therapy which has yet to be discovered. Methods: Regarding the purpose of monitoring the autonomous function of stable 40 regular HD patients and 35 healthy controls, we examined the clinical application of the laser-Doppler blood flow meter (LDF). By detecting the periflux blood flow decreasing velocity (PDV) while combined with the Valsalva manoeuvre, the LDF device which was used for an autonomous test. We also looked at the relationship between PDV and traditional atherosclerosis testing. Results: The baseline PDV (5.30 ± 2.93), comparative to subjects who were in excellent condition (9.65 ± 7.10), was substantially decreased in the HD populace. Furthermore, we discovered a substantial connection between PDV and established parameters like heart rate fluctuation and ankle-brachial blood pressure indexing. Conclusion: Regarding assessing autonomous functioning in hemodialysis patients, evaluation of PDV by LDF is just as effective as the standard approach. The benefit from regular and recurring assessments of autonomous dysfunction is made possible by the device's ease.

THE DISCOURSE OF WHITE SUPREMACY TOWARDS CONFORMATION OF BLACK IDEAL MASCULINITY OF ALFA NDIAYE’S ATTRIBUTES IN DAVID DIOP’S NOVEL AT NIGHT ALL BLOOD IS BLACK
Authors: Akbar Rifqi , Agustin Nerry
Published: June 2023

Colonialism is one of the events of colonization of Europeans or Western nations to a nation or continent with inferior value to its customs, intellectuality, and marginalization. It results in the distingency of social structures that experience racial inequality and discrimination, including black people. White supremacy perpetuates an ideology that can take away the human rights of blacks, especially the ideal identity of masculinity, the black men. Black men are represented as beasts, combat-ready pioneers, obedient slaves, and so on. This representation becomes a construction of an ideological discourse that marginalizes black people. This discourse affects psychological and social dualism and intersectionalism that rests on resistance to white supremacy. This study aims to reveal the discourse of the identity of idealistic masculinity in black men. The method used is descriptive-qualitative. This method is employed in relating the problems that occur to Alfa Ndiaye who experiences the traumatic experience of the death of his best friend in his life journey while tracing racial equality between the countries of Francophone, France-Africa (Senegal). This study uses intersectional, masculinity, and racial studies. The material object is the novel At Night All Blood is Black by David Diop. In contrast, the formal object is ideology's effect in identifying masculinity's attributes in black people, especially in the main character, Alfa Ndiaye. Thus, white hegemony always uses various ways to make the ‘wounded masculinity’ of Ndiaye feel pressured and it is considered that their savagery is beneficial for Captain Armand in raising French independence.
GROTESQUE COMPONENTS IN CHARLES DICKENS’ TO BE TAKEN WITH A GRAIN OF SALT AND MARY ELIZABETH BRADDON’S EVELINE’S VISITANT
Authors: Hajo Suhair Fuaad
Published: June 2023

This paper attempts to define the grotesque and its primary literary features before examining the grotesque components in two Victorian authors' works with the goal of separating their approaches to the grotesque based on gender. The most well-known novelist of the Victorian era, Charles Dickens will be one of the authors covered in this paper through his story To be Taken with a Grain of Salt, and the other one is Mary Elizabeth Braddon’s story Eveline’s Visitant. Dickens and Braddon particularly make use of the grotesque elements to convey their ideas and ideals through satire, comedy, tragedy, suspense, and a sense of fear, gloom, and obscurity. The research results show that both tales can be regarded as significant Victorian grotesque literature since they share, in various ways, elements of the grotesque notion. The real meaning of the grotesque is only exposed by itself-contradictory nature with the opposite, which is in this sense the ideal. Both stories are based on the main contrast between the spiritual and material worlds. They attempt to persuade us that there is yet another mysterious force that, despite the efforts to conceal it in the physical world, it exposes human wrongdoing. Thus, abnormal human beings, ghostly figures, and terrifying events will be detected through which grotesque elements are found.
UNHEARD VOICES: THE LOCATION OF WOMEN AS OTHERNESS IN JEAN RHYS’S WIDE SARGASSO SEA
Authors: Mohammed Saz Hersh , Abdul Zanyar Kareem
Published: June 2023

Jean Rhys’s Wide Sargasso Sea (1966) is a postcolonial story in which Antoinette, the Creole lady, is portrayed as the crazy woman in the attic. Thus, it is possible to see why Antoinette as a protagonist misses her identity and how madness works in a colonial and patriarchal culture by examining the connections between race and gender in Rhys' novel in light of Ania Loomba's ideas about colonialism and postcolonialism and linking it to psychoanalytic feminism with Julia Kristeva's notion of the abject. Race and gender are employed as metaphors for one another and to dehumanize the other among us, driving it insane. Postcolonial critics have debated Antoinette's otherness as a result of colonial rule; whereas, feminist theorists have frequently emphasized the patriarchal aspect of society and the connection between madness and the mother-daughter relationships of the novel. This study focuses on otherness and lunacy, which contains not only colonizer-colonized, male-female, and mother-daughter connections but also self-repression in a patriarchal and colonial culture, leading to Antoinette’s alienation and loss of identity. Overall, black women as being enslaved are picturized as ugly, something without an owner.

Published: June 2023

Error analysis is widely used in EFL teaching and learning to identify the types and causes of errors made by EFL learners and to determine whether those errors are systematic or random. By examining these errors, teachers can develop effective solutions to reduce, eliminate or improve them. The purpose of this study was to investigate the grammatical errors made by senior high school students when composing recount texts. The study used a descriptive quantitative approach by analysing  a corpus of 30 essays written by 15 students. Utilizing Dulay, Burt, Krashen's (1982) framework of surface structure taxonomy for data analysis, the results reveal that students committed errors in four categories: disinformation, misordering, omission, and addition (ordered accordingly from the most to the least produced one). This study implies that recognizing students' writing errors may assist teachers in determining the focus of their instruction in order to enhance student’s learning to a better condition.

Authors:   Production and Metallurgy Engineering Department, University of Technology, Baghdad, Iraq, Mohsein Zainab , Abdulwahhab Ahmed , Noori Diana
Published: June 2023

In machining operations, surface roughness (Ra) is an essential measure of product quality. It is determined by the cutting settings. The parameters that have been worked on are the Feed (F) (0.72, 0.88, 0.96, 1.12 mm/min), depth of cut (DOC) (0.5mm), and spindle speed (N) (545, 710, 1000, 1400 r.p.m). Three types of ferrous metals were employed in this study low-carbon steel St 3, medium-carbon steel St 45, and high-carbon steel Y8. According to the data, the optimal operating condition for obtaining the best surface roughness is 1.119 µm for low-carbon steel. St 3 from the product is by employing the following cutting settings for the cutter (feed 0.72 = mm/rev), (DOC= 0.5mm), and (machine speed =1400 rpm). But when using the cutting variables (feed 1.12 = mm/rev), (DOC = 0.5mm), and (machine speed = 545 rpm) for high-carbon steel Y8, gives the highest surface roughness is 4.999 µm . The experimental findings indicate that the surface roughness of turned components is considerably affected by cutting settings and machine equipment. According to the results of this study, increasing spindle speed lowered the Ra of the turned components, but rising feed increased the surface roughness. The value acquired by this approach will benefit other researchers for future work on tool vibrations, cutting forces, and so on.

The rotor position value is the most important parameter in synchronous machines. In this paper, a MATLAB model of high-resolution rotor position determination at zero speed, without any position sensor, is presented for a non-saturated permanent magnet motor. The motor current and voltage responses for two short pulses were employed to form address lines for memory cells whose contents represent the exact rotor position. The proposed model presents rotor position at 1o resolution and works with salient rotor poles. It could be modified to obtain the results for non-salient poles. The model needs only two current sensors and does not require any special technique for magnet polarity detection. This method was tested successfully for a two-poles machine and it could be applicable to any number of poles.

The author argues that this resilience might not be sustainable and that in the mid-term perspective we might observe some explicit disintegration in the system that affects multilateral institutions, international public law, and the global governance at large. Four independent variables are important in shaping the future world order: the outcome of the Russian-Ukrainian and the Russian-Western confrontation, the dynamics of the US-China relations, the sustainability of Western cohesion, and the prospects for a new cycle of globalization.
Konsens ohne Begründung?

To anyone who is not a positivist with respect to the law existing bioethical regulations must appear unsatisfactory; for the basic values cited to ground them are neither well defined nor adequately justified. Are they not merely the ones currently held by a majority of people in the Western industrialised nations? Might they not be subject to change either over time or in other cultural contexts? If human rights serve only to preserve people's rationally exercised individual freedom then restrictions like those of the German Embryo Protection Act cannot be adequately justified. Tue best chance for a consensus seems to result from the common experience of events intuitively judged as inhuman. lt appears therefore realistic to predict that legal, political and moral norms with respect to the life sciences are only consensually constituted if a society has had a bad experience in that field.
»Wer fürchtet sich vorm Schwarzen Mann?« Fremde Gefühle bei der Pflege kulturfremder Patienten
Authors: Käppeli Silvia
Published: June 2023

It is easy for someone to become marginalised (a »black person« as a German nursery rhyme puts it), i. e. a mixture of knowledge, emotions, hearsay and value judgments. Two observations require attention: 1) People from foreign cultures easily become victims of such judgments. 2) People from one's own culture, too, may come into that position. The phenomenon does not depend on the distance of a culture but on its strangeness. The article lists characteristics of persons from foreign as well as kindred cultures that make them candidates for becoming marginalised. We often meet a climate of prejudice in hospitals. Nursing which is not prepared for transcultural contact can emphasize this situation. Often nurses show feelings towards patients that have not been examined for their inherent prejudices and effects on the patients. Such mechanisms of stigmatisation may influence the practice of nursing. The last part of this paper considers possible solutions to these problems.

La nutrigenómica busca dar respuesta a cómo los nutrimentos intervienen en los procesos de regulación genética del organismo debido a su capacidad para regular la expresión de genes. Los factores de transcripción cumplen una función importante, y su activación puede ser directa o indirecta por determinados nutrimentos. En este artículo se muestra cómo algunos nutrimentos pueden regular genes a través de factores de transcripción implicados en la regulación de procesos vitales para las funciones celulares, cuya alteración ha estado asociada con diversas patologías, como el cáncer, diabetes, obesidad, entre otras. La nutrigenómica ofrece una visión para la creación y el diseño de pautas alimentarias para mejorar la salud de las personas con riesgo de desarrollar estas enfermedades.

Los árboles forman parte de nuestra cotidianidad. Desde la antigüedad las especies nativas son un recurso importante para los mexicanos; los exóticos también se aprovechan. A pesar de su importancia existe poco rigor en trabajos especializados, como flora regional mexicana, artículos científicos o libros. El presente estudio tiene como objetivo registrar las 350 especies, distribuidas en 72 familias, así como mencionar su lugar de origen; siendo Asia quien más aporta flora exótica, seguido de América, Europa, Oceanía y África. Este trabajo representa un punto de partida para dar a conocer la existencia de la flora exótica en el país y así generar estrategias de manejo y aprovechamiento eficaces.
Tres vidas de amor por las palabras: tres diccionarios del español
Authors: Rivero Franyutti Agustín
Published: June 2023

Elaborar un diccionario es seguramente una de las mayores locuras que una persona puede realizar debido al tiempo invertido, pero así son los amantes de las palabras y libros que las contienen: prefieren vivir en los mundos posibles que ellas crean que en los hechos sensoriales anclados al mundo real. Las palabras tienen una vida mucho más dilatada que la nuestra y nos ofrecen perdurar más allá de la extinción material. Los tres autores que se abordan aquí son, en este sentido, inmortales, pues serán recordados por sus obras mientras haya hablantes del español o estudiosos de otros idiomas que se interesen por nuestra lengua; los tres vivieron de manera austera y disciplinada, entregados a la paciente y dura labor de confeccionar las que quizá sean las mejores obras de la lexicografía en español.

Background: Specialization in gynecology and obstetrics is declared by the laws and regulations of individual countries prescribed by the competent Ministry of Health, as well as in Croatia and Bosnia and Herzegovina. Methods: During the daily clinical practice, educational unevenness and dissatisfaction of individual residents were noticed along with other organizational-communication and professional problems in basic obstetric skills, which we objectified by a voluntary anonymous survey of 122 residents of gynecology and obstetrics (RGO) from Croatia and Bosnia and Herzegovina. Residents completed survey during their postgraduate resident education. Results: RGOs state global dissatisfaction with specialization in 78.6%, believe in 84.4% that the skills and number of skills are not consistent with the years of specialization and 89.3% believe that they do not have enough skills to be able to work independently after specialization. Thus, the average number of skills from the first level competencies according to 1–5 years of specialization correlates with the above: the average number of cesarean section is 95.6, vaginal breech delivery extremely low 2.2, vacuum extration 6, forceps in the Croatia and Bosnia and Herzegovina does not perform, care of obstetrics anal sfincter injuries average 3 as well as shoulder distotia, internal version 0.36 and external version 0.6. Thus, 29.5% of them believe that there is a global lack of interest in the specialization system, 31.9% cite the incompetence of mentors, 33.6% the usual practice of individual schools and clinics. In conclusion, 59.8% of RGOs believe that obstetrics is a challenging profession, 10.6% a demanding profession, 18.8% consider it a dangerous occupation, only 13.9% an attractive occupation, and the fact that obstetrics has turned into a profession with caesarean sections as the most common skill is considered by 56.6%, even 84.2% of RGOs in the last year of specialization. Conclusions: There is evidently an academic-professional disproportion between the necessity and need for education and skills, that is, required competencies and reality. We must become and be arbiters between anti-obstetrics and obstetrics full of skills and craftsmanship as a true profession of allopathic conventional medicine, and academic honesty towards RGOs.
Exposure to Therapeutic BTK Inhibitors Induces Phenocopying of Btk29A Mutants in the Fruit Fly Drosophila melanogaster

Background: Bruton’s tyrosine kinase (BTK) is a non-receptor type tyrosine kinase originally identified as the genetic signature responsible for X-linked agammaglobulinemia (XLA) when mutated. Its functional form is required for B lymphocyte maturation in both humans and mice, whereas loss-of-function causes a different form of developmental defect in the fruit fly, Drosophila melanogaster. Methods: Ibrutinib and other therapeutic inhibitors of BTK have been extensively used to successfully treat various leukemias and lymphomas. Btk29A type 2 is the ortholog of BTK in the fruit fly. We show that feeding wild-type flies an ibrutinib-containing diet induces phenocopying of Btk29A mutants, i.e., failure in the fusion of left and right halves of the dorsal cuticles, partial loss of wing tissues and dysregulation of germ cell production. Results: We have previously reported that Btk29A phosphorylates Drosophila Arm (β-catenin), and ibrutinib reduces phosphorylation at Tyrosine142 of endogenously expressed β-catenin in Cos7 cells transfected with Btk29A type 2 cDNA. Conclusions: Thus, Drosophila is suitable for screens of novel BTK inhibitor candidates and offers a unique in vivo system in which the mode of action of BTK inhibitors can be examined at the molecular, cellular, and organismal levels.

Introduction. Preterm birth disrupts important processes of fetal growth and development and can serve as a trigger for maladaptive organ remodeling in the postnatal ontogenesis. The aim of the study was to evaluate the effect of preterm birth on the angiogenesis of the left ventricular myocardium of rats from days 1 to 21 of the postnatal ontogenesis. Materials and methods. We performed immunohistochemical (CD31) and morphometric (specific volume of blood capillaries, specific volume of cardiomyocytes, diameter of blood capillaries, trophic index and pericapillary diffusion zone) study of the left ventricular myocardium of full-term and prematurely born (12 and 24 hours preterm) Wistar rats (n=88) of both sexes on days 1, 7, 14, and 21 of the postnatal ontogenesis. Results. The birth of rats 12 and 24 hours preterm does not result in change in the specific volume of blood capillaries and the trophic index in the left ventricular myocardium on days 1, 7, 14, and 21 of the postnatal period. Preterm birth leads to a decrease in the specific volume of cardiomyocytes of the left ventricular myocardium of rats, compared to the parameters of animals in the control group, on days 7–21 of the postnatal period. Preterm birth results in a decrease in the diameter of the blood capillaries of the left ventricular myocardium in female rats on day 21 of the postnatal period. Preterm birth (24 hours preterm) is accompanied by an increase in the size of the zone of pericapillary diffusion in the left ventricular myocardium of rats on day 14 of the postnatal ontogenesis, in comparison with that of animals in the control group. Conclusion. The shorter the duration of the intrauterine period of development of rats, the greater the severity of the observed changes in the left ventricular myocardium are. It seems promising to study the functional state of endotheliocytes of myocardial blood vessels in preterm animals in the postnatal period. Keywords: preterm birth, prematurity, myocardium, angiogenesis, vascular indexes

Pendidikan adalah salah satu hal terpenting dalam kehidupan setiap manusia. Gagalnya pendidikan juga merupakan kegagalan kehidupan dan masa depan. Selain itu, pendidikan merupakan kebutuhan mutlak yang harus dipenuhi sepanjang hayat. Sebab tanpa Pendidikan mustahil suatu kelompok manusia dapat hidup berkembang sejalan dengan aspirasi (cita-cita) untuk maju (Fuad Ihsan, 2008: 2). Senada dengan hal tersebut, tidaklah dapat dipungkiri bahwa pendidikan bercita-cita untuk meningkatkan kualitas manusia seutuhnya serta masyarakat seluruhnya.
