Top Intera Jaya (TIJ) is a company that focuses on designing and producing high-quality leather bags, wallets, and accessories. TIJ has a monthly production capacity of 50,000 pcs and plans to increase it to 100,000. The company needs better storage capacity and production floor to support this increase. This Community Service Program (CSP) aims to assist TIJ in redesigning the production floor into a raw material and cutting storage warehouse using the shared storage method. The shared storage method organizes warehouse space using the FIFO (First In First Out) principle, where the fastest delivered items are placed in the storage area closest to the exit. This CSP began by conducting interviews with resource persons, namely warehouse staff, to understand the needs of TIJ. After getting an initial overview, the team designed the training materials that TIJ needed. CSP was conducted on February 2, 2024, with the pre-test and post-test results showing an increase in participants' understanding of warehouse design from 33% to 67% and from the results of the training and mentoring, the team and management of TIJ agreed that the shared storage method with the FIFO principle is the best solution that will be implemented for warehouse layout efficiency at TIJ.
Otomycosis, Review
Authors: Al-Oebady Mouna Akeel Hamed , Wali Hawraa F. , Mousa Nuha Mohammed
Published: September 2024

The word "otomycosis" refers to a specific type of fungal infection affecting the external auditory canal. It appears to be a highly prevalent clinical condition seen in otorhinolaryngology outpatient departments worldwide. Most Aspergillus and Candida species are the etiological microorganisms that form biofilm inside the ear canal. The development of otomycosis can be caused by improper self-cleaning, self-medication, and the insertion of needless instruments into the ear canal. Ear pain, discharge from the ears, and hearing loss are the main signs of otomycosis. Therefore, in order to take a percussive action during the primary stage of infection, the correct diagnosis is imperative. However, special medical attention is required, particularly in patients with low immunity, when infection spreads to a mastoid area with a suppurative condition. The purpose of this thorough review is to raise awareness of the importance of good health education and self-hygiene in order to maintain a healthy lifestyle. The majority of cases of otomycosis affect one ear, and immunocompromised patients are more likely to experience bilateral involvement. The most often mentioned risk factors include swimming, applying mustard oil to ears, overusing antibiotic ear drops, using Q-tips, wooden sticks, metal pickers, and self-cleaning of ears with these items. Staphylococcus aureus is the most frequently implicated bacterium in cases of concurrent otomycosis. In order to lower the incidence of otomycosis, this literature review emphasizes the necessity of education in order to eliminate the previously mentioned predisposing risk factors.

Determining the shelf life and best preservation strategy for food products is crucial to guaranteeing their safety and nutritional value. This research aimed to assess the duration of post-weaning food made from senescent plantains, soybeans, maize, and fish may be stored, as well as the most effective means of preserving them. The approach included storing the pre-prepared instant flours at two different conditions: room temperature (30 ±2 °C) and in the refrigerator (4 °C) for a duration of six months. Physicochemical, biochemical, and microbiological studies were conducted on the flours at the time of their production, followed by two-month intervals until the end of the sixth month. The findings indicated that the ash content remained constant throughout the duration of the investigation. Nevertheless, no notable alterations were detected in the pH, titrable acidity, dry matter, protein, and fat composition. There was a clear discrepancy between the start of production and the end of the shelf-life investigation. However, the levels observed at the end of the trial were in line with the established standards for post-weaning baby food. Both during manufacture and at the end of the storage trial, the flours demonstrated good microbiological quality. Flours kept at room temperature had the most nutritional value, but those stored in the refrigerator were devoid of GAM, yeast, and mold starting from the fourth month of preservation. Flours stored in this way maintained their nutritional qualities and were appropriate for newborn nourishment even after six months of storage.

Brown tumors are a rare complication of hyperparathyroidism resulting from abnormalities in bone metabolism. Advances in biological exploration techniques enable early diagnosis before the onset of bone manifestations. While mandibular involvement is the most common in the maxillofacial region, maxillary involvement is extremely rare. We report a case of a patient with primary hyperparathyroidism revealed by a maxillary tumor. The pathological result concluded a benign giant cell tumor of the maxilla and fibrous dysplasia. The diagnosis of a brown tumor was considered based on the association of radiological data (osteolytic image and parathyroid adenoma), histological findings (giant cell tumor), and biological markers (hypercalcemia, hypophosphatemia, and elevated Parathyroid Hormone (PTH). This case highlights the difficulty in establishing a correct diagnosis in patients with an osteolytic maxillary process and the need to investigate hyperparathyroidism in the presence of a giant cell lesion.

The Untold Symbolic Significance of African Cultures, the Case of the Bukusu Circumcision Ritual in Kenya
Authors: Mayende Godfrey Banda
Published: September 2024

Most Africans cultures were observed and practiced within the confines of their moral values that carried coded meaning which required more attention to understand hidden symbolism contained therein. Among the Bukusu people of Western Kenya for instance, circumcision was perhaps a cultural routine that was practiced with strict observance of several stages and rituals that indirectly communicated important messages to the initiates and the society at large. Hence, this paper examines key stages that are involved in order to successfully complete a Bukusu circumcision ritual. Such phases contained unique features and moral values that have not been told in many academic and scholarly writings since the inception of African leadership after colonialism. For the success in this objective, the tenets of the structural functionalism approach were very relevant in the illustration of the significance of the ritual itself and its key components that are deeply embedded and enshrined in the doctrines that dictated the operations of this rite. The study heavily relied on primary data which was corroborated by the existing secondary date to generate findings contained in this paper. Much of the primary data was collected through Oral Interviews (abbreviated as O.I in the entire text) and also through extensive readings from the Kenya National Archives (abbreviated as KNA in the text).
Proposal of Educational Models and a Simulation Program for Learning Piezosurgery in Stomatology, Implantology and Maxillofacial Surgery
Authors: Turki Imen Mehri
Published: September 2024

Background and Objective: The acquisition of technical skills, using piezosurgery devices, would be facilitated by simulation on educational models. This study aims to disseminate a simulation program and propose educational models of animal origin enabling progressive achievement of psychomotor skills in learning piezosurgical procedures. Material: As part of the national continuing education program in stomatology, implantology, and maxillofacial surgery that we founded and have been leading since 2015, seven procedural simulation sessions for piezosurgery training were realized. The simulation program included two steps: first, specific tasks carried out on a sheep's head to learn psychomotor skills using piezoelectric device. Then, similar tasks were reproduced on a hen egg to reach a higher level of mastery and proficiency. The program and simulation models were evaluated according to a questionnaire by 200 practitioners at the end of each session. Results: Almost all participants reported that working on a sheep head authentically reproduced the tasks, that were completed after at least two attempts, with a feeling of projection into the clinical environment. All participants considered that undermining the membrane from the eggshell reproduced the same gesture on the Schneiderian membrane. However, only 30% of practitioners achieved this task on the hen egg requiring more than five attempts. Conclusion: The simulation program using the educational models that we have proposed allows us to carry out in the first stage of the simulation the basic learning of technical gestures in a high-fidelity environment and the second stage considered as an advanced simulation, to acquire a higher level of competence and technical capacity. Our simulation method is simple, inexpensive, and reliable to become standardized and followed on a larger scale in learning piezosurgical skills.

Understanding the effectiveness of such strategies is paramount. This study investigates the impact of data-driven decision-making on business performance in the context of a diverse set of industries. The primary objective of this research is to assess the extent to which data-driven strategies influence business performance. Specifically, we aim to quantify the correlation between the adoption of data-driven approaches and key performance indicators (KPIs) such as revenue growth, cost reduction, and customer satisfaction. A comprehensive mixed-methods approach was employed. Qualitative data was collected through interviews with executives from 15 companies across different sectors. Quantitative data was obtained through surveys distributed to 25 organizations. Statistical analysis, including correlation and regression analysis, was conducted to identify patterns and relationships. Our analysis reveals a strong positive correlation between the adoption of data-driven strategies and business performance metrics. On average, companies that embraced data-driven decision-making experienced a 20% increase in revenue, a 15% reduction in operational costs, and a 10% improvement in customer satisfaction compared to those that did not. This study underscores the transformative potential of data-driven strategies in contemporary business environments. Organizations that leverage data effectively not only enhance their financial performance but also better meet customer expectations. We conclude that data-driven decision-making is no longer a luxury but a strategic imperative for businesses looking to thrive in the digital age.

Published: September 2024

The world energy demand rises due to population growth and other economic and political factors. The electrical energy generation source from renewable energy resources such as solar and wind energy can mitigate the problem. The technology of harnessing solar energy for electricity generation using PV is prominent. Integrating PV with wind turbine to form a hybrid system could be the best alternative. This work involved the use of improved Hybrid Optimization Model for Genetic Algorithm (iHOGA) for feasibility analysis of hybrid solar photovoltaic (PV)-wind energy system for power supply to office building in Aliero, Nigeria. The appliances required for office building includes: lighting points, standing fans, charging points and small scale portable refrigerator. The result from feasibility analysis revealed that, PV energy system generated 2,300 kWh energy and release 54.3% and 26.1% of it for serving the load and the auxiliary load. The wind energy system generated 420 kWh which is 68.2% less than the 1,320 kWh load demand. The hybrid PV-wind energy system generated 2,620 kWh and serves the load with only 46.6% and export 37.4% to auxiliary load, 4.2 % energy loss due to batteries and zero or negligible unmet load, while the remaining 11.8 % is losses through the inverter and charge controller. Therefore, 135 W PV module could be hybridize with 200 W wind turbine, two (2) pieces of 200 Ah batteries, 40 A charge controllers and 1600 VA inverter for portable power supply to the building. The net present cost (NPC), cost of energy (COE) and carbon dioxide (CO2) emission for the optimal PV-wind hybrid energy system are $ 22,229.3, 0.9024 $/kWh and 104 kg/yr respectively. Therefore, based on this design, hybrid PV-wind energy system is more reliable and stable energy system.

Dalam investasi di sektor keuangan dikenal kaidah, “jangan menyimpan telur di keranjang yang sama”. Jika kita menyimpan telur dalam satu keranjang dan lalu keranjang itu jatuh, maka keseluruhan telur akan pecah. Namun bila kita membagi telur tersebut ke dalam beberapa keranjang, maka jika ada satu keranjang yang jatuh, simpanan telur di keranjang lainnya masih selamat. Kaidah tersebut menjelaskan pentingnya melakukan diversifikasi untuk meminimalisir resiko keruguian serta memaksimalkan keuntungan. Kaidah ini tidak hanya relevan diberlakukan dalam investasi di sektor keuangan, namun juga relevan diaplikasikan dalam investasi di sektor riil, termasuk pelaku UKM. Untuk meningkatkan kinerja UKM dalam negeri, hal ini perlu disebar luaskan dan diperkenalkan pada para pelaku UKM.

Introduction: Temporomandibular dysfunction (TMD) involves a variety of conditions that affect the temporomandibular joint (TMJ) and associated structures, generating symptoms such as pain, limited movement and joint noise. Given the anatomical complexity of the TMJ and the diversity of symptoms, accurate diagnosis is challenging. Magnetic resonance imaging (MRI) stands out as an effective test for assessing soft tissues, such as the articular disc, and can detect disc displacements, joint effusion and inflammation. Aim: This study aims to assess whether MRI is the most appropriate test for diagnosing temporomandibular disorders, taking into account divergent opinions among specialists and the scientific literature. Materials and Methods: An integrative literature review was carried out using PubMed, Scopus and Web of Science databases, as well as Google Scholar for gray literature. Controlled descriptors were used, combined with Boolean operators. Results and Discussion: Although MRI is effective for assessing soft tissues and disc displacements, it has limitations in detecting bone abnormalities, which can compromise a comprehensive diagnosis. Therefore, the combination of other imaging techniques is recommended for a complete evaluation. Conclusion: MRI is an important tool, but not sufficient on its own. The complementary use of other diagnostic modalities is essential for an accurate diagnosis of TMD.
Effect of Quartz and Red-Clay to Phonolite Ratios on Some Properties of Floor Tile
Authors: Aljarany Ali
Published: September 2024

This research paper presents the procedure of preparing and testing of experimental ceramic slabs in order to examine and investigate some of their physical and mechanical properties. These slabs were divided into two types; type (I) includes slabs made of either Quartz, Phonolite, Red-Clay, Green-Clay or Kaoline, whereas, type (II) includes slabs various in their Quartz and Red-Clay to Phonolite ratios. Other constituents of type (II) slabs such as Green-Clay, Kaoline were intentionally kept comparable for the sake of comparisons. Methods of preparing and testing of the experimental ceramic slabs were performed according to the technical constraints and facilities available at the Investment Complex for Manufacturing Building Materials (INCOMA) at Misurata-Libya. Several tests and measurements have been done on the experimental ceramic slabs of both types. The physical properties of type (I) slabs and raw materials ceramic powder were investigated with the determination of their water absorption, thermal shrinkage, heat lose, bulk density and fluidity. The breaking strength and impact resistance of type (II) slabs were also determined. These results were enhanced with surface and cross-sectional metallographic investigations for both types of experimental slabs. It is thought that the presence of a considerable amounts of oxides such as CaO, K O and Fe O in the Red-Clay decreased significantly the fractural strength, but improved the impact resistance of the experimental ceramic slabs. Conversely, the presence of high alumina and silica contents together with trace amount of ZrO in the Phonolite probably behind the improvement of their fractural strength, and decline of the impact resistance of the experimental ceramic slabs.
Effectiveness Factor of Concrete Based on Lower - Bound Analysis of Deep Beams Strengthened with CFRP
Authors: Hassan Maissa , Khatab Mahmoud
Published: September 2024

The effectiveness factor of concrete is existing to overcome the shortcomings of applying the plasticity theorem to analyse the behaviour of reinforced concrete and account for the limited ductility of concrete. The value of the effectiveness factor mainly depends on the material properties, the geometrical dimensions and the reinforcement details. There is disagreement among different codes of practice on the value of the effectiveness factor. The main aim of this research is to propose a new equation for the effectiveness factor of concrete that can be implemented in the lower-bound analysis of simply supported deep beams strengthen with CFRP. Moreover, the study assesses the use of different effectiveness factor expressions in the lower bond analysis of deep beams strengthened with CFRP. A model of a strut and tie is proposed to predict the final load for simply supported deep beams that fail to shear, taking into account the effect of the total depth of the deep beams and the angle of inclination of the strut according to the design codes. The accuracy of the proposed model is verified based on a database of 126 samples collected from previous studies. The analysis showed that the shear strength of deep beams strengthened with CFRP depends on more than one variable. Among the different effectiveness factor equations considered in this investigation, for the range of beams considered, the most accurate prediction was achieved using the proposed effectiveness factor equation with a mean of 1.00, a standard deviation of 17% and a coefficient of variation of 2.0%.

the main purpose of this research is to study analytically the CFT columns using the finite element method. ANSYS computer program is employed, in order to evaluate the behavior of the CFT short columns. 3-D finite element model is presented and calibrated successfully in order to predict the performance of the CFT columns under axial static loading. This paper presents the results of analytically study on the performance of axially loaded concrete-filled steel box columns subjected to different loading cases. The study investigates the effect of these loads on both axial capacity and ductility of CFT columns for different loading cases. The study investigates the effect of these loads on both axial capacity and ductility of CFT columns for different loading cases. This effect is studied for each type of loading individually. From the results it is obvious that in case CFT columns with load acting on total area of steel and concrete increasing both stiffness and strength can be attributed to the composite action between the steel tube and the concrete infill. Therefore, the composite action between the steel tube and the concrete not only The steel tube work as longitudinal reinforcing bars to resist the loads as ties or spirals to confine the concrete infill but also both strength and ductility of the concrete are enhanced.

The Unconfined Compressive Strength of Hy-drated Lime Stabilized Clayey Soil at Different Water Contents and Different Curing Times
Authors: Salem Ahmad
Published: September 2024

This research was done to find out how adding hydrated lime and extra water content to clayey soil samples affecting their unconfined compressive strength (UCS). The clayey soil is a locally available soil from the clayey soil area in Cyrene, northeastern of Libya. In the soil samples, hydrated lime (HL) was added at a rate of 5% of the dry weight of the soil. The standard compaction test was conducted on the untreated natural soil sample “NS” so that the optimum water content at the maximum dry density can be determined wop1. Because of the addition of hydrated lime to the soil will affect the dry density-water content relationship, the standard compaction test was conducted again on the treated soil sample “NS+5%HL” to determine another optimum water content wop2. These optimum water values {wop1 =17.8 & wop2=19.5} will be used to prepare unconfined compressive strength specimens. In the experimental work two soil mixtures will be used beside the natural soil mixture. The first mixture "NS+5%HL+wop1" and the second mixture "NS+5%HL+wop2" were prepared in addition to the natural soil mixture "NS+wop1". All unconfined compressive strength specimens for the first and second mixtures were extracted and tested at 7 and 14 days of curing, then comparison were made. The first mixture, "NS+5%HL+wop1" will be compared with the natural soil mixture, "NS+ wop1" in order to understand the impact of HL addition. The effect of the water content changing can be seen when the second mixture, "NS+5%HL+wop2" is compared with the first mixture, NS+5%HL+wop1. According to the findings, Although the first mixture’s specimens have the least dry density value, the UCS values increased by 218.5 and 386.5% at 7 and 14 days of curing, respectively, when compared to the natural soil mixture. This illustrates the result of the added hydrated lime. At curing times of 7 and 14 days, respectively, the UCS values for the second mixture fell by 8.61 and 14.11% when compared to the first mixture. And this illustrates the impact of variations in water content.

Authors: Sawalem Mohamed , Aburwais Mustafa
Published: September 2024

In one of the lathes (TACCHI FTC 100) used in the central workshop of the Libyan Iron and Steel Company, a number of bearings are used to support all the pieces to be turned. In this research, we tried to study the stresses arising in the bearings used in this lathe and the extent of their responsibility for the failure of the bearing, and the total deformation of the bearing under loading conditions was examined by using finite element analysis . Through the analysis, it became clear that the maximum resulting stresses in the bearings (2.68673×107N/M2 ) did not exceed the yield stress of the bearing material (Chromium Stainless Steel 100 Cr6), and also did not produce significant deformations in the bearings (only 0.0376373 mm ) , and this means that the resulting stresses were not the cause of the bearings failure, which is likely to occur for other reasons.

Authors: Klaib Alhadi
Published: September 2024

Nowadays Extensible Mark-up Language (XML) is a dominant technology for formatting and exchanging data across the Internet world. Updating and retrieving a massive amount of XML data is an interesting and active research area. In addition, indexing XML data is a significant task to improve the efficiency of XML queries. Labelling nodes is the used technique for indexing XML data efficiently. There are many labelling schemes that have been proposed. However, these schemes have many limitations and shortcomings. Therefore, this paper aims to propose a new XML labelling scheme that addresses the issue of efficiency of XML query performance. Thus, this paper developed a new XML labelling scheme. Consequently, four experiments were designed in order to evaluate this. The results of these experiments suggest that the proposed scheme achieved the target results and showed an improvement in the performance and the efficiency of labelling XML documents.

Single Curvature Bending of Structural Stitched Textile Reinforcements Part I: Experimental Work
Authors: Bu Jldain Hafeth
Published: September 2024

Aerospace structural components made from polymer matrix composites (PMCs) offer numerous advantages. Their high stiffness and high strength combined with low densities enable lower fuel consumption coupled with higher payloads. As a result, PMCs provide an important economic advantage over typical metallic airframes. Textile reinforcements for PMCs are made by assembling reinforcement fibres, typically carbon. Then, the textile reinforcements are typically cut into smaller pieces, stacked, draped and assembled into a dry assembly called a preform, the shape of which generally approaches that of the PMC part to be made. This manufacturing process is labour intensive and expensive.Novel thick, net-shape, drapable, high fibre volume fraction (vf) textile reinforcements used toward manufacturing aerospace PMCs are being developed at the University of Ottawa. The technology enables the manufacturing of flat, drapable multilayered near net-shape preforms. The bending and in-plane shear behaviours of such novel thick reinforcement textiles was investigated to understand and define the behaviour of such thick fabric reinforcements when formed into required shapes. A bending apparatus was developed for investigating the bending behaviour of these novel thick reinforcement fabrics.

Due to an account of its excellent hardness and wear behavior, AISI D2 is used widely in producing of blanking and cold-forming dies, Punches, Shafts, Studs, and Bolts. Increasing toughness at a fixed high level of hardness is growing requirement for this kind of applications. Improving microstructure characteristics, especially carbides distribution by specific heat treatment, is an appropriate way to meet such requirement. The effect of quenching media on microstructure and hardness of pre-heated and austentized (at 980oC) AISI-D2 tool steel has been studied, and hardness and carbides morphology have been investigated. Three different medias, water, oil and water/oil (time quenching) have been used, then all samples were followed by the same tempering 350oC/1 hour. It has been found that the optimal carbides distribution and optimum hardness have been resulted from a time quenching method.
Durability-Related Transport Properties of Limestone Calcined Clay Cement Mortars
Authors: Alferjani Saad , Abubaker Farhat
Published: September 2024

This study investigates the effect of utilizing a combination of limestone and calcined clay as cement re-placement on the transport properties that indirectly define the behavior of the matrix throughout its service life, such as total porosity, water absorption due to capillary action, water permeability penetration, chlorine diffusion, and car-bonation depth. Mortars were made of blends with different levels of cement replacement (%15, %30, %45) by a substi-tution ratio of 2:1 (calcined clay: limestone), with adjusted gypsum content in each system composition. Furthermore, the influence of kaolinite content in clays on transport prop-erties was also investigated. Based on the results, all LC3 blends exhibited a significant improvement in terms of total porosity, capillary water absorption, water penetration re-sistance, and chloride diffusion compared to OPC mortars. Moreover, the higher the replacement level of cement, the higher the resistance to movement or transport of ion spe-cies through the mortars. The improvement in the transport properties for LC3 blends can be attributed to its enhanced porosity refinement as well as the enhanced chloride bind-ing capacity. In contrast, a slight improvement in the transport properties was observed with increasing the kao-linite content of the calcined clays. This result indicates that utilizing low-grade calcined clay has no significant effect on the transport properties. The carbonation resistance of the LC3 blends was lower as compared to OPC. Furthermore, increasing the cement substitution rate resulted in a pro-gressive decrease in carbonation resistance. Overall, an in-crease in cover depth would be required to achieve a similar service life in terms of carbonation as that of the OPC.
Tracking Control of a Continuous Stirred Tank Reactor Using Advanced Control Algorithms
Authors: Abougarair Ahmed
Published: September 2024

The Continuous Stirred Tank Reactor (CSTR) is a common type of industrial equipment used in chemical processes with second-order nonlinear dynamics. CSTR is a nonlinear and linked nature makes it challenging to develop a robust control with a bigger operating zone. In the process industry, a CSTR is a crucial component. It serves as a foundation for studying and controlling other chemical reactors. Good state estimation and disturbance rejection are required in industrial processes. The most important characteristic for CSTR operation is temperature. The behavior is obtained by steady-state and dynamic analysis of the model which is usually represented by a set of differential equations. An event-based Neural network, Model Predictive Control (MPC), and Model Reference Adaptive Control (MRAC) controller are presented in this work to provide robustness to the system with the added benefit of conserving energy expenditure under parameter variations and fast changing dynamics. Numerical simulations were used to confirm the controller's robustness and efficacy. In comparison to the ANN and MPC, the simulation results clearly show that the MRAC technique delivers appropriate performance in terms of process functional improvements, more flexibility, and improved system-tracking precision in control action.

Wireless technology is increasingly influenced by the advanced technological development of antennas. With the rapid expansion of Internet of Things ( IoT) application in the contemporary communication networks, the demand for small printed antennas is increasing, due to their small size and ease of design and manufacture to suit their various application. In this paper, the antenna is designed which is operating at two different frequency bands 2.40GHz and 5.78GHz. The design parameters of the antenna have been calculated using the transmission line model, and an antenna design program has been used for the simulation process is HFSS ( High frequency simulator structure ) tool, which is based on Finite Element Method (FEM). In this work, the proposed slot dual band patch antenna is implemented using FR4 substrate material with a thickness 1.6mm and relative permittivity 4.4. The size of the proposed antenna is just (28 × 27.7mm). The proposed antenna has Omni-directional radiation patterns on most of the operating band. The dual band antenna is designed by adding a slot to the top of the radiated patch. Therefore, the proposed dual- band antenna shows good performance, which is suitable for modern wireless communications and Internet of Things (IoT) applications. The measurements are found to be in good accordance with the simulated results.
