While most pregnant women in Gharyan city demonstrated adequate oral health knowledge, gaps persist in

preventive practices, particularly regarding fluoride use and dental visits. Education level and dental visits

during pregnancy were significant determinants of knowledge. These findings highlight the need for targeted

oral health education programs and increased access to dental services for pregnant women to improve oral

health outcomes for both mothers and their infants.

Abstract

Obesity and headache are conditions associated with a substantial personal and societal impact. This study aims to evaluate the association between body mass index (BMI) and Headache among adults in Gharyan City, Libya. This was a descriptive cross-sectional study, conducted at Gharyan city, Libya, during the period from December 2024 to March 2025. Two hundred (200) participants, including 94 males (47%) and 106 females (53%), were enrolled in this study. Data were collected by using a structured questionnaire. The participants were divided into four categories, based on BMI: underweight (<18.5), normal weight (18.5 to 24.9), overweight (25 to 29.9), and obese (>30). A total of 200 participants, both gender males and females, were enrolled in this study during the study period. The study indicates that high percentage of headache in age was 43 -56 years, and severe obesity BMI > 30 kg/m2 were observed of high percentage in females n=27 (25.47%) compared to males n=17 (18.08%), although the severe obesity and headache found in females n=37 (34.90%), rather than males n=30 (31.91%) Obesity and headache are both, slightly more common in females than males, we recommend that more studies among obesity and headache in large patients should be done, although small sample size and lack of long-term flow-up of patients, were the main limitations of our study and results suggested a need for monitoring by X-ray and MRI diagnosis of patients have obesity

ABSTRACT This study investigates the effects of self-assessment on students’ motivation and language proficiency among English Department students at the Faculty of Arts, AL-Assaba. A quantitative research design was adopted, using a questionnaire distributed to a sample of 60 students. The findings indicate that self-assessment plays a significant role in enhancing learners’ motivation, self-awareness, and perceived language proficiency. Most students reported positive attitudes toward self-assessment and felt it Improved their English skills. The study concludes that incorporating self-assessment into English language instruction can foster learner autonomy and Improve learning outcomes. It recommends Integrating self-assessment practices into curricula and providing guidance to students on effective self-assessment. Keywords: Self-assessment, Motivation, Language Proficiency, Learner Autonomy, English Department Students, Higher Education.  

Abstract: 

This study presents a critical discourse analysis (CDA) of the construction of political identity 

during periods of revolutionary crisis. It examines the dichotomous representation of Muammar 

Gaddafi in February 2011 through two primary data streams: his first major public address 

following the uprising (February 22, 2011) and the contemporaneous visual and textual 

coverage in three newspapers—The Sun (UK), The Daily News (a prominent US tabloid-style 

outlet), and Alshourouq (Egypt). Employing Fairclough’s (1992) three-dimensional model of 

CDA, Halliday’s (1978) Systemic Functional Linguistics (SFL), and Kress and van Leeuwen’s 

(2006) grammar of visual design, the analysis reveals a profound disjuncture between Gaddafi’s 

linguistic self-fashioning and his mediated portrayal. Findings indicate that Gaddafi’s speech 

strategically deployed lexical choices, transitivity, and modality to construct identities of a 

rightful leader, paternal protector, and historical embodiment of Libya. Conversely, the selected 

newspapers, despite ideological nuances, converged on a representational framework depicting 

Gaddafi as weak, cowardly, and delegitimized, primarily through specific visual framing, 

camera angles, and captions. This study argues that the conflict between these representations 

is not merely descriptive but deeply ideological, reflecting the struggle for discursive hegemony 

during the Arab Spring, where control over narrative became a key battleground alongside 

military confrontation.

Background and objective :Helicobacter pylori [H.pylori] infection is one of the most common chronic bacterial infections worldwide especially in the developing countries. This bacterium is the cause of many diseases such as MALT lymphoma, gastritis, peptic ulcers, and stomach cancer. According to recent reports, H.pylori infection may increase the risk of colorectal cancer. The current study aimed at investigating the association of H. pylori infection and the risk of colorectal cancer and adenomatous polyps. Methods: The current study was conducted on 52 patients with colon cancer as the case group and 200 subjects without pathological finding (i e, polyps, neoplasms, or inflammatory diseases) as the control group. Blood samples were collected from the patients in order to assess the presence of anti-H. pylori infection antibodies by the serum titer levels of anti-H. pylori IgG antibodies were measured using enzyme-linked immunosorbent assay (ELISA) with commercial kit by (Dia.Pro Diagnostic Bioprobes-Italy). Results: This study demonstrates distinct associations between H.pylori infection markers and CRC risk. While IgG seropositivity showed a significant 2.16-fold increased CRC risk (p = 0.019). Conclusion: This research finding IgG seropositivity may serve as a broader risk marker.

This paper presents the design and implementation of a smart robotic vacuum cleaner based on Internet of Things (IoT) technologies, named IO-VAC, specifically developed for smart home environments. The paper covers both the mechanical and electronic aspects of the robot’s development. A 2D layout was created using ArchiCAD to define the positioning of components and sensor angles when designing the robot, followed by a 3D model to visualize the final design. The robot chassis was fabricated using reinforced plastic to ensure durability and lightweight structure. The IO-VAC is controlled using an Arduino Mega board programmed in C/C++. Where, the system includes three ultrasonic sensors for obstacle avoidance, along with an infrared (IR) sensor for edge detection to prevent falls. The embedded system of IO-VAC integrates an ESP8266 Wi-Fi module, allowing for remote control via the Blynk IoT platform to enable users to control the robot’s movement (forward, backward, left, right), adjust suction power, select the desired cleaning algorithm, and monitor the battery level in real-time. In this paper three movement algorithms were developed: random, spiral and zigzag, and their performance was tested on two types of surfaces smooth and rough to ensure reliability and efficiency in various cleaning conditions after testing the validation of IO-VAC. Based on the test results of robot performance, the zigzag algorithm proved to be the most effective in terms of covered area, cleaning mission time, power consumption and minimizing redundancy. This work demonstrates an effective integration of embedded systems with IoT technologies, offering a smart and cost-efficient solution for automating household cleaning tasks.
