Suggesting new words to extract keywords from title and abstract
No full textWhen talking about the fundamentals of writing research papers, we find that keywords are still present in most research papers, but that does not mean that they exist in all of them, we can find papers that do not contain keywords. Keywords are those words or phrases that accurately reflect the content of the research paper. Keywords are an exact abbreviation of what the research carries in its content. The right keywords may increase the chance of finding the article or research paper and chances of reaching more people who should reach them. The importance of keywords and the essence of the research and address is mainly to attract these highly specialized and highly influential writers in their fields and who specialize in reading what holds the appropriate characteristics but they do not read and cannot read everything. In this paper, we extract new keywords by suggesting a set of words, these words were suggested according to the many mentioned in the researches with multiple disciplines in the field of computer. In our system, we take a number of words (as many as specified in the program) that come before the proposed words and consider it as new keywords. This system proved to be effective in finding keywords that correspond to some extent with the keywords developed by the author in his research
Reliability analysis of the Stress-Strength model from truncated Pareto distribution based on progressive Type-II censored samples.
No full textIn this project, we studied the stress strength reliability (SSR) models. The stress-strength model has many applications in engineering problems, for example the strength of a building being subjected to earthquake, the strength of a rocket motor being greater than its working pressure, and the strength of a bridge. We estimated the reliability parameter using maximum likelihood estimation method in three cases (arbitrary case, common truncated case, and common resilience parameter case). We computed the maximum likelihood estimator (MLE) of the reliability parameter R and studied the properties of the estimator of the parameter R using a great amount of simulation studies and illustrate our method through some real data examples. Moreover, we compute the generalized confidence intervals passed on pivotal quantities. We computed the bootstrap confidence intervals. We found that, the confidence interval is wider in the arbitrary parameter case, and that there is no large difference between the estimators of reliability parameter using different methods
The perception of smile attractiveness among Saudi population
No full textHadeel A Mokhtar, Layla W Abuljadayel, Reem M Al-Ali, Mohammed Yousef Department of Operative Dentistry, Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia Abstract: Parameters of dental beauty change across time for varying reasons. Thus, an understanding of the factors that help or harm the attractiveness of a smile is an important step in creating attractive smiles. This study aimed to identify factors that affect smile perception and attractiveness among the Saudi population. A cross-sectional study was conducted among the Saudi population. Questionnaires were distributed to 130 dentists and final-year dental students, and to 130 laypersons. The questionnaire contained six smile photographs created by Photoshop® software. There was a statistically significant difference in scale ratings, based on participant background, for the “gummy: smile picture (P-value =0.003), diastema picture (P-value =0.000) and the “Reverse” smile picture (P-value =0.004). As for sex, males significantly underscored the gummy picture (P-value =0.009). Older people accepted the gummy smile less than did younger people, but diastema was considered as one of the variations that spoiled the attractiveness of the smile. “Dental background” participants significantly identified the ideal smile better than the “nondental” group. The perception of diastema as a sign of beauty among Saudi population in the past has definitely changed, according to the results of our study, where diastema and reverse smile received the lowest score in this survey. Keywords: diastema, gummy, revers

This study aimed to investigate the association between hypothyroidism and periodontal disease in a cohort of adult Saudi population.Methods: This case–control study included 201 adults with hypothyroidism on hormone replacement therapy and 188 healthy controls. The medical files of patients were reviewed to check thyroid stimulation hormone (TSH) and free thyroxine (FT4) levels. Participants completed a questionnaire on demographic and health information, followed by a comprehensive periodontal examination. Pearson chi-square and binary logistic regression analyses determined associations, with a significance set at p ≤ 0.05.Results: Gingivitis was found in 20.9% of cases and 58% of controls. Periodontitis stages I, II, III and IV were in general higher in cases compared to controls (23.4%, 27.9%, 21.9%, 6% in cases versus 13.8%, 17%, 9.6%, 1.6% in controls, respectively). Mean PPD and CAL values were higher in cases (5.54 ± 2.5 and 3.88 ± 3.1) than in controls (4.03 ± 1.6 and 1.72 ± 2.4). Significant associations between periodontal status and hypothyroidism were found (p < 0.0001). The periodontal status in hypothyroid cases correlated significantly with hormone replacement therapy dose and duration (p < 0.0001).Conclusion: The findings of the current study showed that, in a cohort of adult Saudi subjects, patients with hypothyroidism have higher prevalence and more severe periodontal disease symptoms compared to controls, suggesting significant association.Keywords: hypothyroidism, periodontal diseases, hormone replacement therapy, association, case–control stud
Impact of Psychological Abuse, Physical Abuse, Sexual Abuse, and Neglect During Childhood on Criminal Behavior among Prisoners at Forensic Mental Health Department
No full textIntroduction: Childhood maltreatment, including physical, emotional, sexual abuse, and neglect, has been consistently linked to a higher likelihood of aggressive and criminal behaviour in adulthood. This phenomenon, often referred to as the "cycle of violence," perpetuates across generations. Furthermore, victimization during childhood can lead to a broad range of mental health problems, including personality disorders, psychosis, schizophrenia, and substance abuse. These issues are particularly prevalent among individuals within the forensic mental health system. Objectives: The study aims to evaluate the impact of psychological abuse, physical abuse, sexual abuse, and neglect during childhood on criminal behaviour among prisoners at forensic mental health department. Methods: A cross-sectional descriptive study was conducted to determine the impact of child abuse on criminal behaviour among prisoners in the Forensic Medicine Department. The study was during the period from December 19, 2022 to 15th of July 2024. The research has been carried out at Baghdad City\u27s Al-Rashad Training Hospital. non-probability purposive sample procedures, this study sampling method relied on our judgment when identifying and selecting prisoners in the forensic medicine department, after their consent, who could provide the best information to achieve the objectives of the study. We choose purposive sampling because we want to focus in depth on relatively small samples (150) to get the most accurate results. a purposive sample of (110) prisoners was selected from Al-Rashad Training Hospital. Results: The findings indicate that prisoners having moderate to high level of psychological abuse during childhood among items. Prisoners having moderate to high level of physical abuse during childhood among items. The findings indicate that prisoners having moderate to high level of sexual abuse during childhood among items. The prisoners having moderate to high level of neglect during childhood among items. The prisoners have high level of criminal behaviour. There are significant relationships between (psychological, physical, sexual abuse) during childhood and criminal behaviour. Conclusions: Prisoners experience a moderate to high level of psychological abuse, physical abuse, and neglect during childhood, and the prisoners also experience a moderate to high level of sexual abuse during childhood
Adverse effect of Abuse During Childhood on Criminal Behavior and Type of Crime among Prisoners at Forensic Mental Health Department
No full textA quantitative approach using a descriptive-analysis design was used in the present study to find out the impact of child abuse on criminal behavior among prisoners in the forensic department. The period of the study was from 16th of October 2023 to 10th of June 2024. The study has been conducted at Al-Rashad Training Hospital which is located in of Baghdad City. Non-probability sampling techniques in which prisoners are selected because they have characteristics that we need in our sample. In other words, prisoners are selected “on purpose” as purposive sampling. Also the judgmental sampling, this sampling method relies on our judgment when identifying and selecting the prisoners that can provide the best information to achieve the study’s objectives. We choose purposive sampling because the researcher wants to focus in-depth on relatively small samples. A purposive sample of (110) prisoners was selected from Al-Rashad Training Hospital. The study sample in this research was selected from prisoners in the forensic department in the hospital. Results: Prisoners have moderate to high level of psychological abuse during childhood. They have moderate to high level of physical abuse during childhood. prisoners having moderate to high level of sexual abuse during childhood. Also they have moderate to high level of neglect during childhood. As overall prisoners have high level of abuse during childhood. prisoners having moderate to high level of criminal behavior subdomain (socialization). related to criminal behavior subdomain (Social conditions) among prisoners; the findings indicates that prisoners having moderate to high level of criminal behavior subdomain (Social conditions) among items. The findings indicates that prisoners having moderate to high level of criminal behavior subdomain (Personal and psychological circumstances) among items. Prisoners have high level of criminal behavior as overall. There is high significant relationship between Abuse during childhood and Criminal behavior at p-value= .004. There are significant relationships between (psychological, physical, sexual abuse) during childhood and criminal behavior at p-value= 0.05. There are no significant relationships between neglect during childhood and criminal behavior. There is no significant relationship between Abuse during childhood and type of crime at p-value= .05
Effect of alcoholic extract of soy bean consumption by pregnant mice on the testis and epididymis of their male offspring's
No full textSoy is flavones are phytoestrogens with potential hormonal activity due to their similar chemical structure to 17-B-estradiol. The increasing availability of Soy
is flavones throughout the food supply and through use of supplements has prompted extensive research on biological benefits to humans in chronic disease
prevention and health maintenance. The objective of this study was to assess the effect of consumption of soy bean by pregnant mice on histomorphology of testis, epididymis in the male offspring's. Twenty pregnant female mice at age of six weeks were used as a model for this study.
After 40 days (around the puberty age) the animals were sacrificed to get their testes and epididymis each testis and epididymis was weighted, then prepared
using routine histological technique mouse born from mother treated with Soy bean extract (1.5mg daily), Note the absence of mature sperms and the appearance of immature sperms in the lumen seminiferous tubules and the appearance immature sperms connected to the germinal epithelium, and also we note in the epididymis of young male mouse from mother treated with soy bean extract absence of mature
sperms in the lumen of the epididymis. Diameters of seminiferous tubules and epididymis together with the thickness of their germinal wall were calculated, these observation indicate that the perinatal exposure of male mice to is flavones affected in testies and epididymis, and they imply that Soy bean has potential implication for testis function
Ab initio structural and vibrational properties of GaAs diamondoids and nanocrystals
No full textGallium arsenide diamondoids structural and vibrational properties are investigated using density functional theory at the PBE/6-31(d) level and basis including polarization functions. Variation of energy gap as these diamondoids increase in size is seen to follow confinement theory for diamondoids having nearly equiaxed dimensions. Density of energy states transforms from nearly single levels to band structure as we reach larger diamondoids. Bonds of surface hydrogen with As atoms are relatively localized and shorter than that bonded to Ga atoms. Ga-As bonds have a distribution range of values due to surface reconstruction and effect of bonding to hydrogen atoms. Experimental bulk Ga-As bond length (2.45 Å) is within this distribution range. Tetrahedral and dihedral angles approach values of bulk as we go to higher diamondoids. Optical-phonon energy of larger diamondoids stabilizes at 0.037 eV (297 cm-1) compared to experimental 0.035 eV (285.2 cm-1). Ga-As force constant reaches 1.7 mDyne/Å which is comparable to Ga-Ge force constant (1.74 mDyne/Å). Hydrogen related vibrations are nearly constant and serve as a fingerprint of GaAs diamondoids while Ga-As vibrations vary with size of diamondoids
استكشاف العناصر القوطية في "ورق الجدران الأصفر": قصة نفسية عن القهر والجنون
No full textThis paper delves into the intricate tapestry of Gothic elements embedded within Charlotte Perkins Gilman\u27s renowned short story, “The Yellow Wallpaper.” Drawing on the author\u27s personal experiences and the prevalent socio-cultural context of the late 19th century, this study aims to unravel the profound psychological implications of the Gothic genre as manifested in the narrative. Through a meticulous analysis of key motifs, symbols, and thematic elements, the paper examines how the Gothic genre serves as a vehicle for exploring themes of female subjugation, psychological deterioration, and societal repression. By dissecting the protagonist\u27s descent into madness within the confining walls of her bedroom, this research sheds light on the oppressive forces that society imposes on women, particularly during the Victorian era. Furthermore, the study investigates how the dark and foreboding atmosphere, intricate descriptions, and the unreliable narrative voice contribute to the overall Gothic ambiance, evoking a sense of claustrophobia and fear. Ultimately, this paper underscores the significance of “The Yellow Wallpaper” as a powerful portrayal of the psychological toll imposed by societal norms, while highlighting the enduring relevance of the Gothic genre in exposing the hidden horrors of human existence.يستكشف هذا البحث نسيج العناصر القوطية المعقدة المتجسدة في قصة شارلوت بيركنز جيلمان "ورق الجدران الأصفر". باستناده إلى تجارب الكاتبة الشخصية والسياق الاجتماعي والثقافي السائد في أواخر القرن التاسع عشر، تهدف هذا الدراسة إلى كشف الآثار النفسية العميقة للخصائص القوطية كما تتجلى في السرد. من خلال تحليل دقيق للموضوعات والرموز والعناصر الرئيسية، يستكشف البحث كيف يعمل الرعب بصفته وسيلة لاستكشاف مواضيع القهر النسائي والتدهور النفسي والقمع الاجتماعي. عن طريق تحليل انحدار البطلة في الجنون داخل جدران غرفتها المغلقة، يلقي هذا البحث الضوء على القوى القمعية التي يفرضها المجتمع على النساء، لا سيما في العصر الفكتوري. علاوة على ذلك، يستكشف البحث كيف تساهم الأجواء المظلمة والمخيفة، والوصف المتقن، والصوت السردي المبهم في أجواء الرعب العامة؟ مما يثير شعورًا بالاحتباس والخوف، وفي النهاية، يسلط هذا البحث الضوء على أهمية "ورق الجدران الأصفر" بصفتها تصويرا قويا للعبء النفسي الذي تفرضه القوانين الاجتماعية، مع تأكيد كشف الرعب المخفي في وجود الإنسان
