environmental problems. A new bio-composites product without synthetic adhesive or resin is possible to be developed in order to reduce these problems. Apart from formaldehyde release, adhesive is also considered to be expensive, especially in the manufacturing of composite products. Natural bonded composites can be termed as a panel product composed with any type of cellulosic materials without the addition of synthetic resins. It is composed with chemical content activation in the cellulosic materials. Pulp and paper making method (chemical pulping) was used as a general guide in the composites manufacturing. This method will also generally reduce the manufacturing cost and the risk of formaldehyde emission and has potential to be used as an alternative technology in fiber composites industries. In this study, the natural bonded bamboo fiber composite was produced from virgin Malaysian bamboo fiber (Bambusa vulgaris). The bamboo culms were chipped and digested into fiber using this pulping method. The black liquor collected from the pulping process was used as a natural binding agent in the composition. Then the fibers were mixed and blended with black liquor without any resin addition. The amount of black liquor used per composite board was 20%, with approximately 37% solid content. The composites were fabricated using a hot press machine at two different board densities, 850 and 950 kg/m³, with two sets of hot pressing time, 25 and 35 minutes. Samples of the composites from different densities and hot pressing times were tested in flexural strength and internal bonding (IB) for strength performance according to British Standard. Modulus of elasticity (MOE) and modulus of rupture (MOR) was determined in flexural test, while tensile force perpendicular to the surface was recorded in IB test. Results show that the strength performance of the composites with 850 kg/m³ density were significantly higher than 950 kg/m³ density, especially for samples from 25 minutes hot pressing time. Strength performance of composites from 25 minutes hot pressing time were generally greater than 35 minutes. Results show that the maximum mean values of strength performance were recorded from composites with 850 kg/m³ density and 25 minutes pressing time. The maximum mean values for MOE, MOR and IB were 3251.84, 16.88 and 0.27 MPa, respectively. Only MOE result has conformed to high density fiberboard (HDF) standard (2700 MPa) in British Standard for Fiberboard Specification, BS EN 622-5: 2006. Microstructure characteristics of composites can also be related to the strength performance of the composites, in which, the observed fiber damage in composites from 950 kg/m³ density and overheat of black liquor led to the low strength properties, especially in IB test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bamboo%20fiber" title="bamboo fiber">bamboo fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20bonded" title=" natural bonded"> natural bonded</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20liquor" title=" black liquor"> black liquor</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20tests" title=" mechanical tests"> mechanical tests</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure%20observations" title=" microstructure observations"> microstructure observations</a> </p> <a href="https://publications.waset.org/abstracts/73780/strength-performance-and-microstructure-characteristics-of-natural-bonded-fiber-composites-from-malaysian-bamboo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73780.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Effects of Viscous Dissipation on Free Convection Boundary Layer Flow towards a Horizontal Circular Cylinder </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Khairul%20Anuar%20Mohamed">Muhammad Khairul Anuar Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Zuki%20Salleh"> Mohd Zuki Salleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anuar%20Ishak"> Anuar Ishak</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Aida%20Zuraimi%20Md%20Noar"> Nor Aida Zuraimi Md Noar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the numerical investigation of viscous dissipation on convective boundary layer flow towards a horizontal circular cylinder with constant wall temperature is considered.

It has been widely investigated and beneficial in the sports context. However, the imagery application in equestrian sport has been understudied. Thus, the effectiveness of imagery should encompass the application in the equestrian sport to ensure its application covert all sports. Unlike most sports (e.g., football, badminton, tennis, ski) which are both mental and physical are dependent solely upon human decision and response, equestrian sports involves the interaction of human-horse collaboration to success in the equestrian tasks. This study aims to investigate the effect of PETTLEP imagery on equestrian jumping tasks, motivation and imagery ability. It was hypothesized that the use of PETTLEP imagery intervention will significantly increase in the skill equestrian jumping tasks. It was also hypothesized that riders’ imagery ability and motivation will increase across phases. The participants were skilled riders with less to no imagery experience. A single-subject ABA design was employed. The study was occurred over five week’s period at Universiti Teknologi Malaysia Equestrian Park. Imagery ability was measured using the Sport Imagery Assessment Questionnaires (SIAQ), the motivational measured based on the Motivational imagery ability measure for Sport (MIAMS). The effectiveness of the PETTLEP imagery intervention on show jumping tasks were evaluated by the professional equine rider on the observational scale. Results demonstrated the improvement on all equestrian jumping tasks for the most participants from baseline to intervention. Result shows the improvement on imagery ability and participants’ motivations after the PETTLEP imagery intervention. Implication of the present study include underlining the impact of PETTLEP imagery on equestrian jumping tasks. The result extends the previous research on the effectiveness of PETTLEP imagery in the sports context that involves interaction and collaboration between human and horse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PETTLEP%20imagery" title="PETTLEP imagery">PETTLEP imagery</a>, <a href="https://publications.waset.org/abstracts/search?q=imagery%20ability" title=" imagery ability"> imagery ability</a>, <a href="https://publications.waset.org/abstracts/search?q=equestrian" title=" equestrian"> equestrian</a>, <a href="https://publications.waset.org/abstracts/search?q=equestrian%20jumping%20tasks" title=" equestrian jumping tasks"> equestrian jumping tasks</a> </p> <a href="https://publications.waset.org/abstracts/82648/the-effect-of-pettlep-imagery-on-equestrian-jumping-tasks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82648.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Thermal Effects of Disc Brake Rotor Design for Automotive Brake Application </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Shahril">K.

Treated (with chemical modifier) and untreated (without chemical modifier) composites were prepared in the formulation of 10 wt%, 20 wt%, 30 wt%, and 40 wt%. The mechanical testing indicates that composite with 10 wt% of untreated composite has the optimum value of tensile strength, and the composite with chemical modifier shows the tensile strength was increased. By increasing of filler loading, elastic modulus was increased while the elongation at brake was decreased. Meanwhile, the swelling test discerned that the increase of filler loading increased the water absorption of composites and the presence of chemical modifier reduced the equilibrium water absorption percentage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coconut%20fiber" title="coconut fiber">coconut fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title=" polypropylene"> polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20acrylic" title=" acid acrylic"> acid acrylic</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20modifier" title=" chemical modifier"> chemical modifier</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a> </p> <a href="https://publications.waset.org/abstracts/14842/effect-of-chemical-modifier-on-the-properties-of-polypropylene-pp-coconut-fiber-cf-in-automotive-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14842.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">461</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Social Entrepreneurship on Islamic Perspective: Identifying Research Gap</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Adib%20Abd%20Muin">Mohd Adib Abd Muin</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuhairimi%20Abdullah"> Shuhairimi Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Azizan%20Bahari"> Azizan Bahari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Problem: The research problem is lacking of model on social entrepreneurship that focus on Islamic perspective.

It appears that many antibiotics, when used at low concentrations, have in common the ability to activate or repress gene transcription, which is distinct from their inhibitory effect. There have been comparatively few studies on the potential of antibiotics as a specific chemical signal that can trigger a variety of biological functions. Therefore, this study was carried out to determine the effect of Streptomycin Sulfate in regulating extracellular proteins secreted by Bacillus subtilis ATCC21332. Results of Microdilution assay showed that the Minimum Inhibition Concentration (MIC) of Streptomycin Sulfate on B. subtilis ATCC21332 was 2.5 mg/ml. The bacteria cells were then exposed to Streptomycin Sulfate at concentration of 0.01 MIC before being further incubated for 48h to 72 h. The extracellular proteins secreted were then isolated and analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Proteins profile revealed that three additional bands with approximate sizes of 30 kDa, 22 kDa and 23 kDa were appeared for the treated bacteria with Streptomycin Sulfate. Thus, B. subtilis ATCC21332 in stressful condition with the presence of Streptomycin Sulfate at low concentration could induce the extracellular proteins secretion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20subtilis%20ATCC21332" title="Bacillus subtilis ATCC21332">Bacillus subtilis ATCC21332</a>, <a href="https://publications.waset.org/abstracts/search?q=streptomycin%20sulfate" title=" streptomycin sulfate"> streptomycin sulfate</a>, <a href="https://publications.waset.org/abstracts/search?q=extracellular%20proteins" title=" extracellular proteins"> extracellular proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a> </p> <a href="https://publications.waset.org/abstracts/11187/extracellular-protein-secreted-by-bacillus-subtilis-atcc21332-in-the-presence-of-streptomycin-sulfate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">284</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Dual Solutions in Mixed Convection Boundary Layer Flow: A Stability Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anuar%20Ishak">Anuar Ishak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mixed convection stagnation point flow toward a vertical plate is investigated.

In this work, investigation on the effect of coupling agent, maleic anhydride polypropylene (MAPP) on the mechanical, morphological and thermal properties of polypropylene (PP) reinforced with durian skin fibre (DSF) was conducted. The presence of 30 wt% DSF significantly reduced the tensile strength of PP-DSF composite. Interestingly, even though the same trend goes to PP-DSF with the presence of MAPP, the reduction is only about 4% relative to unreinforced PP and 18% higher than PP-DSF without MAPP (untreated composite or UTC). The used of MAPP in treated composite (TC) also increased the tensile modulus, flexural properties and degradation temperature. The enhanced mechanical properties are consistent with good interfacial interaction as evidenced under scanning electron microscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=durian%20skin%20fiber" title="durian skin fiber">durian skin fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling%20agent" title=" coupling agent"> coupling agent</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=thermogravimetry%20analysis" title=" thermogravimetry analysis"> thermogravimetry analysis</a> </p> <a href="https://publications.waset.org/abstracts/33625/effect-of-coupling-agent-on-the-properties-of-durian-skin-fibre-reinforced-polypropylene-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33625.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">464</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> The Development of GPS Buoy for Ocean Surface Monitoring: Initial Results</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anuar%20Mohd%20Salleh">Anuar Mohd Salleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Effendi%20Daud"> Mohd Effendi Daud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a kinematic positioning approach which is use the GPS buoy for precise ocean surface monitoring. A GPS buoy data from two experiments have been processed using a precise, medium-range differential kinematic technique. In each case the data were collected for more than 24 hours at nearby coastal site at a high rate (1 Hz), along with measurements from neighboring tidal stations, to verify the estimated sea surface heights. Kinematic coordinates of GPS buoy were estimated using the epoch-wise pre-elimination and the backward substitution algorithm. Test results show the centimeter level accuracy in sea surface height determination can be successfully achieved using proposed technique.

This study was conducted to identify the healthy and BSR-infected oil palm tree using thirteen color indices. Multispectral and thermal camera was used to capture 216 images of the leaves taken from frond number 1, 9 and 17. Indices of normalized difference vegetation index (NDVI), red (R), green (G), blue (B), near infrared (NIR), green – blue (GB), green/blue (G/B), green – red (GR), green/red (G/R), hue (H), saturation (S), intensity (I) and thermal index (T) were used. From this study, it can be concluded that G index taken from frond number 9 is the best index to differentiate between the healthy and BSR-infected oil palm trees. It not only gave high value of correlation coefficient (R=-0.962), but also high value of separation between healthy and BSR-infected oil palm tree. Furthermore, power and S model developed using G index gave the highest R2 value which is 0.985. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20palm" title="oil palm">oil palm</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=disease" title=" disease"> disease</a>, <a href="https://publications.waset.org/abstracts/search?q=leaves" title=" leaves"> leaves</a> </p> <a href="https://publications.waset.org/abstracts/28605/identification-of-healthy-and-bsr-infected-oil-palm-trees-using-color-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">498</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Functional Slow Release of Encapsulated Ibuprofen in Cross-linked Gellan Gum Hydrogel for Tissue Engineering Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nor%20Jannah%20Mohd%20Sebri">Nor Jannah Mohd Sebri</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairul%20Anuar%20Mat%20Amin"> Khairul Anuar Mat Amin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dication cross-linked gellan gum hydrogel loaded with Ibuprofen with excellent mechanical properties had been synthesized as potential candidate for non-toxic biocompatible polymer material in tissue engineering.

Reasons for this are unclear, but may be related to a lack of suitable instrumentation and entropy theory. We integrate single probe thermal gradient for the radial conduction of a short-duration heat pulse away from a single electrode source, and compared it with the theory for an instantaneously heated line source. By measuring the temperature response at a short distance from the line source, and applying short-duration heat-pulse theory, we can extract all the entropy properties, the thermal diffusivity, heat capacity, and conductivity, from a single heat-pulse measurement. Results of initial experiments carried out on air-dry sand and clay materials indicate that this heat-pulse method yields soil thermal properties that compare well with thermal properties measured by single electrode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entropy" title="entropy">entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20probe%20thermal%20gradient" title=" single probe thermal gradient"> single probe thermal gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20thermal" title=" soil thermal"> soil thermal</a>, <a href="https://publications.waset.org/abstracts/search?q=probe%20heat" title=" probe heat "> probe heat </a> </p> <a href="https://publications.waset.org/abstracts/5201/evaluation-of-soil-thermal-entropy-properties-with-a-single-probe-heat-pulse-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5201.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Temperature Distribution in Friction Stir Welding Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armansyah">Armansyah</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20P.%20Almanar"> I.

In order to obtain temperature distribution in the welded aluminum plates during welding operation, transient thermal finite element analyses are performed. Heat input from tool shoulder and tool pin are considered in the model. A moving heat source with a heat distribution simulating the heat generated by frictions between tool shoulder and workpiece is used in the analysis. Three-dimensional model for simulated process is carried out by using Altair HyperWork, a commercially available software. Transient thermal finite element analyses are performed in order to obtain the temperature distribution in the welded Aluminum plates during welding operation. The developed model was then used to show the effect of various input parameters such as total rate of welding speed and rotational speed on temperature distribution in the workpiece. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frictions%20stir%20welding" title="frictions stir welding">frictions stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20distribution" title=" temperature distribution"> temperature distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=altair%20hyperwork" title=" altair hyperwork"> altair hyperwork</a> </p> <a href="https://publications.waset.org/abstracts/14092/temperature-distribution-in-friction-stir-welding-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14092.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">543</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Detection of Mycobacteria spp by PCR in Raw Milk Samples Collected from Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shokoufeh%20Roudashti">Shokoufeh Roudashti</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Bahari"> Shahin Bahari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fakhri%20Haghi"> Fakhri Haghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20Zeighami"> Habib Zeighami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghazal%20Naderi"> Ghazal Naderi</a>, <a href="https://publications.waset.org/abstracts/search?q=Paniz%20Shirmast"> Paniz Shirmast</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Mycobacterium tuberculosis complex (MTBC) causes tuberculosis (TB) in humans and animals. Mycobacterium MTBC is one of the most important species of zoonotic pathogens that can be transmitted from cattle to humans. The disease can transmit to human by direct contact with the infected animals, drinking unpasteurized milk and consumption of uncooked meat. The presence of these opportunistic, pathogenic bacteria in bovine milk has emerged as a public-health concern, especially among individuals who consume raw milk. Tuberculosis MTBC is the predominant infectious cause of morbidity and morality worldwide, It is estimated that one third of the world population (approx. 1.8 billion persons) is infected with M. tuberculosis and each year there are 8 million new cases worldwide. The aim of this study, to detect Mycobacterium MTBC in raw milk samples using polymerase chain reaction (PCR). Materials and Methods: In the present study, 60 raw milk samples were collected from rural areas in Zanjan, Iran. After extraction of DNAs and using special primers for Is6110 gene as a marker, PCR was applied to detect the presence or non-presence of the related gene. Results: According to the findings of this study, 8 (13.5 %) out of 60 milk samples were positive for Mycobacterium spp (P < 0.1). Conclusions: The Outbreak of genus Mycobacteria spp in milk samples were determined to be relatively high in Zanjan, Iran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacteria%20spp" title="Mycobacteria spp">Mycobacteria spp</a>, <a href="https://publications.waset.org/abstracts/search?q=raw%20milk" title=" raw milk"> raw milk</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=Zanjan" title=" Zanjan"> Zanjan</a> </p> <a href="https://publications.waset.org/abstracts/37406/detection-of-mycobacteria-spp-by-pcr-in-raw-milk-samples-collected-from-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37406.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Evaluation of Site Laboratory Conditions Effect on Seismic Design Characteristics in Ramhormoz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sayyed%20Yaghoub%20Zolfegharifar">Sayyed Yaghoub Zolfegharifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairul%20Anuar%20Kassim"> Khairul Anuar Kassim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Khoramrooz"> Hossein Khoramrooz</a>, <a href="https://publications.waset.org/abstracts/search?q=Khodayar%20Farhadiasl"> Khodayar Farhadiasl</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadegh%20Jahan"> Sadegh Jahan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Iran is one of the world's seismically active countries so that it experiences many small to medium earthquakes annually and a large earthquake every ten years. Due to seism tectonic conditions and special geographical and climatic position, Iran has the potential to create numerous severe earthquakes. Therefore, seismicity studies and seismic zonation of seismic zones of the country are necessary. In this article, the effect of local site conditions on the characteristics of seismic design in Rahmormoz will be examined. After analyzing the seismic hazard for Rahmormoz through deterministic and statistical methods and preparing the necessary geotechnical models based on available data, the ground response will be analyzed for different parts of the city based on four inputs and acceleration level estimated for bedrock through the equivalent linear method and by means of Deep Soil program. Finally, through the analysis of the obtained results, the seismic profiles of the ground surface for different parts of the city will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20microzonation" title="seismic microzonation">seismic microzonation</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20response" title=" ground response"> ground response</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance%20spectrum" title=" resonance spectrum"> resonance spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=period" title=" period"> period</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20conditions" title=" site conditions"> site conditions</a> </p> <a href="https://publications.waset.org/abstracts/35992/evaluation-of-site-laboratory-conditions-effect-on-seismic-design-characteristics-in-ramhormoz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35992.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> The Significant Effect of Wudu’ and Zikr in the Controlling of Emotional Pressure Using Biofeedback Emwave Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Anuar%20Awang%20Idris">Mohd Anuar Awang Idris</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nubli%20Abdul%20Wahab"> Muhammad Nubli Abdul Wahab</a>, <a href="https://publications.waset.org/abstracts/search?q=Nora%20Yusma%20Mohamed%20Yusoff"> Nora Yusma Mohamed Yusoff</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wudu’ (Ablution) and Zikr are amongst some of the spiritual tools which may help an individual control his mind, emotion and attitude.

Many researchers take an interest in the study of Primates and their environment for the reason that they are intimately connected to humans in terms of human social behaviors. In this context, a study of the activity budget of monkeys was conducted in three states of Peninsular Malaysia. The chi-square test was served to analysis the behaviors and their variances in different study areas, effects of seasonal variation on behaviors, time differences in behaviors and habituated and non-habituated behaviors of monkeys. In consequent the behavior of moving (17%) was found higher followed by climbing (15%), eating (13%), and other social behaviors. All the behavior categories were found significant at p<0.05. The most common behavior of the monkeys in conclusion has been found associated with the restiveness of the animal and that their colony size is not rigid as it depends also on some other factors. This study can therefore serve as a starting point for the understanding of comparative behaviors of monkey in general and the study of the monkey behavior is thus recommended to be expanded to cover more study areas as well as species than in the present work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activity%20budget" title="activity budget">activity budget</a>, <a href="https://publications.waset.org/abstracts/search?q=Peninsular%20Malaysia" title=" Peninsular Malaysia"> Peninsular Malaysia</a>, <a href="https://publications.waset.org/abstracts/search?q=monkeys%20colony" title=" monkeys colony"> monkeys colony</a>, <a href="https://publications.waset.org/abstracts/search?q=behaviour" title=" behaviour"> behaviour</a> </p> <a href="https://publications.waset.org/abstracts/48479/colony-size-and-behaviors-characteristics-of-monkeys-in-peninsular-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48479.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Design and Development of Fleet Management System for Multi-Agent Autonomous Surface Vessel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zulkifli%20Zainal%20Abidin">Zulkifli Zainal Abidin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Shahril%20Mohd%20Ghani"> Ahmad Shahril Mohd Ghani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agent-based systems technology has been addressed as a new paradigm for conceptualizing, designing, and implementing software systems. Agents are sophisticated systems that act autonomously across open and distributed environments in solving problems. Nevertheless, it is impractical to rely on a single agent to do all computing processes in solving complex problems. An increasing number of applications lately require multiple agents to work together. A multi-agent system (MAS) is a loosely coupled network of agents that interact to solve problems that are beyond the individual capacities or knowledge of each problem solver. However, the network of MAS still requires a main system to govern or oversees the operation of the agents in order to achieve a unified goal. We had developed a fleet management system (FMS) in order to manage the fleet of agents, plan route for the agents, perform real-time data processing and analysis, and issue sets of general and specific instructions to the agents. This FMS should be able to perform real-time data processing, communicate with the autonomous surface vehicle (ASV) agents and generate bathymetric map according to the data received from each ASV unit. The first algorithm is developed to communicate with the ASV via radio communication using standard National Marine Electronics Association (NMEA) protocol sentences. Next, the second algorithm will take care of the path planning, formation and pattern generation is tested using various sample data. Lastly, the bathymetry map generation algorithm will make use of data collected by the agents to create bathymetry map in real-time. The outcome of this research is expected can be applied on various other multi-agent systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomous%20surface%20vehicle" title="autonomous surface vehicle">autonomous surface vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=fleet%20management%20system" title=" fleet management system"> fleet management system</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20agent%20system" title=" multi agent system"> multi agent system</a>, <a href="https://publications.waset.org/abstracts/search?q=bathymetry" title=" bathymetry"> bathymetry</a> </p> <a href="https://publications.waset.org/abstracts/72389/design-and-development-of-fleet-management-system-for-multi-agent-autonomous-surface-vessel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72389.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">271</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Recycling Motivations and Barriers in Kota Kinabalu, Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jasmine%20Adela%20Mutang">Jasmine Adela Mutang</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosnah%20Ismail"> Rosnah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Chua%20Bee%20Seok"> Chua Bee Seok</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferlis%20Bahari"> Ferlis Bahari</a>, <a href="https://publications.waset.org/abstracts/search?q=Lailawati%20Madlan"> Lailawati Madlan</a>, <a href="https://publications.waset.org/abstracts/search?q=Walton%20Wider"> Walton Wider</a>, <a href="https://publications.waset.org/abstracts/search?q=Rickless%20Das"> Rickless Das</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Waste projection is increasing and most landfills in Malaysia are running out of space. Due to that, waste management is now becoming a major challenge. The most sustainable solution is by practicing sustainable practices such as recycling. Since 1993 the government has launched several recycling campaigns and implemented the National Recycling Policy. However, public participation is still very low. Only 10.5% of solid waste was recycled up to now which is far below than of in developed countries. Nevertheless the government is optimistic that the target of 22% recycling by 2020 will be achieved if there is a positive flow pattern in sustainable practices in particular recycling behavior among Malaysian. Understanding public motivations towards recycling domestic waste are important to improve current recycling rate. Thus this study attempts to identify what are the possible motivations and hindrances for the public to recycle. Open-ended questions format were administered to 484 people in Kota Kinabalu, Sabah, Malaysia. Two specific questions we asked to explore their general determinants and barriers in practicing recycling: “What motivates you to recycle?” and “What are the barriers you encountered in doing recycling activities?” Thematic analysis was conducted on the open-ended questions in which themes were created with the raw comments. It was found that the underlying recycling motivations are awareness’ towards the environment, benefits to the society and individual, and social influence. Non participations are influence by attitudes, commitment, facilities, knowledge, inconvenience, and enforcement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycling%20motivation" title="recycling motivation">recycling motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20barrier" title=" recycling barrier"> recycling barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20waste" title=" household waste"> household waste</a> </p> <a href="https://publications.waset.org/abstracts/34243/recycling-motivations-and-barriers-in-kota-kinabalu-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34243.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">553</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Dual Band LoRa/GPS Dipole Antenna with Harmonic Suppression Capability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amar%20Danial%20Abd%20Azis">Amar Danial Abd Azis</a>, <a href="https://publications.waset.org/abstracts/search?q=Shipun%20Anuar%20Hamzah"> Shipun Anuar Hamzah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Noh%20Dalimin"> Mohd Noh Dalimin</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairun%20Nidzam%20Ramli"> Khairun Nidzam Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Sani%20Yahya"> Mohd Sani Yahya</a>, <a href="https://publications.waset.org/abstracts/search?q=Fauziahanim%20Che%20Seman"> Fauziahanim Che Seman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the design, simulation results, and testing of a compact dual-band printed dipole antenna operating at frequencies of 916 MHz and 1.57 GHz for LoRa and GPS applications, respectively. The basic design of this antenna uses a linear dipole that operates at 916 MHz and 2.7 GHz. A small triangular-shaped linear balun has been developed as the matching network. Parasitic elements are employed to tune the second frequency to 1.57 GHz through a parametric study. Meanwhile, a stub is used to suppress the undesired 2.6 GHz frequency. This antenna is capable of operating on dual-frequency bands simultaneously with high efficiency in suppressing the unwanted frequency. The antenna exhibits the following parameters: return loss of -18.5 dB at 916 MHz and -14 dB at 1.57 GHz, VSWR of 1.25 at 868 MHz and 1.5 at 1.57 GHz, and gain of 2 dBi at 916 MHz and 2.75 dBi at 1.57 GHz. The radiation pattern of the antenna shows a directional E-plane and an omnidirectional H-plane at both frequencies. With its compact size and dual-band capability, this antenna demonstrates great potential for use in IoT applications that require both LoRa and GPS communication, particularly in applications where a small yet efficient form factor is essential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual%20band" title="dual band">dual band</a>, <a href="https://publications.waset.org/abstracts/search?q=dipole%20antenna" title=" dipole antenna"> dipole antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20elements" title=" parasitic elements"> parasitic elements</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonic%20suppression" title=" harmonic suppression"> harmonic suppression</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa%20and%20Gps" title=" LoRa and Gps"> LoRa and Gps</a> </p> <a href="https://publications.waset.org/abstracts/194483/dual-band-loragps-dipole-antenna-with-harmonic-suppression-capability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194483.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">6</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Physicochemical Attributes of Pectin Hydrogel and Its Wound Healing Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nor%20Khaizan%20Anuar">Nor Khaizan Anuar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Karimah%20Aziz"> Nur Karimah Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Tin%20Wui%20Wong"> Tin Wui Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Sazali%20Hamzah"> Ahmad Sazali Hamzah</a>, <a href="https://publications.waset.org/abstracts/search?q=Wan%20Rozita%20Wan%20Engah"> Wan Rozita Wan Engah </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The physicochemical attributes and wound healing activity of pectin hydrogel in rat models, following partial thickness thermal injury were investigated. The pectin hydrogel was prepared by solvent evaporation method with the aid of glutaraldehyde as crosslinking agent and glycerol as plasticizer. The physicochemical properties were mainly evaluated using differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy, while the wound healing activity was examined by the macroscopic images, wound size reduction and histological evaluation using haematoxylin and eosin (H&E) stain for 14 days. The DSC and FTIR analysis suggested that pectin hydrogel exhibited higher extent of polymer-polymer interaction at O-H functional group in comparison to the unprocessed pectin. This was indicated by the increase of endothermic enthalpy values from 139.35 ± 13.06 J/g of unprocessed pectin to 156.23 ± 2.86 J/g of pectin hydrogel, as well as the decrease of FTIR wavenumber corresponding to O-H at 3432.07 ± 0.49 cm-1 of unprocessed pectin to 3412.62 ± 13.06 cm-1 of pectin hydrogel. Rats treated with pectin hydrogel had significantly smaller wound size (Student’s t-test, p<0.05) when compared to the untreated group starting from day 7 until day 14.

The results show that the ZnO nanorods are successfully grown on the sample annealed at 50°C in the sonicated ZnO nutrient solution with a length and a diameter of approximately 8.025 µm and 92 nm, respectively. However, no ZnO nanorods structures are observed for the sample annealed at 50°C and grown in unsonicated ZnO nutrient solution. Meanwhile, the ZnO nanorods for the sample annealed at 100°C are successfully grown in both sonicated and unsonicated ZnO nutrient solutions. The length and diameter of the nanorods for the sample grown in the sonicated solution are 8.681 µm and 1.033 nm, whereas those for the sample grown in the unsonicated solution are 7.613 µm and 1.040 nm. This result shows that with ultrasonic treatment, the length of the ZnO nanorods increases by 14%, whereas their diameter is reduced by 0.7%, resulting in an increase of aspect ratio from 7:1 to 8:1. Electroconductivity and pH sensors are used to measure the conductivity and acidity level of the sonicated and unsonicated solutions, respectively. The result shows that the conductivity increases from 87 mS/cm to 10.4 mS/cm, whereas the solution pH decreases from 6.52 to 6.13 for the sonicated and unsonicated solutions, respectively. The increase in solution conductivity and acidity level elucidates the higher amount of zinc nutrient in the sonicated solution than in the unsonicated solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20treatment" title="ultrasonic treatment">ultrasonic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20annealing%20temperature" title=" low annealing temperature"> low annealing temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO%20nanostructure" title=" ZnO nanostructure"> ZnO nanostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=nanorods" title=" nanorods"> nanorods</a> </p> <a href="https://publications.waset.org/abstracts/10106/ultrasonic-assisted-growth-of-zno-nanorods-at-low-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Analysis of Vocal Fold Vibrations from High-Speed Digital Images Based on Dynamic Time Warping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20I.%20A.%20Rahman">A.

This paper presents a Dynamic Time Warping (DTW) based approach to analyze and objectively classify vocal fold vibration patterns. The proposed technique was designed and implemented on a Glottal Area Waveform (GAW) extracted from high-speed laryngeal images by delineating the glottal edges for each image frame. Feature extraction from the GAW was performed using Linear Predictive Coding (LPC). Several types of voice reference templates from simulations of clear, breathy, fry, pressed and hyperfunctional voice productions were used. The patterns of the reference templates were first verified using the analytical signal generated through Hilbert transformation of the GAW. Samples from normal speakers’ voice recordings were then used to evaluate and test the effectiveness of this approach. The classification of the voice patterns using the technique of LPC and DTW gave the accuracy of 81%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20time%20warping" title="dynamic time warping">dynamic time warping</a>, <a href="https://publications.waset.org/abstracts/search?q=glottal%20area%20waveform" title=" glottal area waveform"> glottal area waveform</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20predictive%20coding" title=" linear predictive coding"> linear predictive coding</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20laryngeal%20images" title=" high-speed laryngeal images"> high-speed laryngeal images</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilbert%20transform" title=" Hilbert transform"> Hilbert transform</a> </p> <a href="https://publications.waset.org/abstracts/9923/analysis-of-vocal-fold-vibrations-from-high-speed-digital-images-based-on-dynamic-time-warping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9923.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Ergonomics: Solutions for the Prevention of Injuries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhamad%20Ammar%20Bin%20Mohd%20Asri">Muhamad Ammar Bin Mohd Asri</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Hamizan%20Bin%20Yusof"> Muhammad Hamizan Bin Yusof</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Haziq%20Bin%20Abdul%20Khalil"> Muhammad Haziq Bin Abdul Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Esman%20Hanief%20Bin%20Khairul%20Anuar"> Esman Hanief Bin Khairul Anuar</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Fikri%20Bin%20Ishak"> Muhammad Fikri Bin Ishak</a>, <a href="https://publications.waset.org/abstracts/search?q=Amril%20Azim%20Bin%20Mohd%20Norrahim"> Amril Azim Bin Mohd Norrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Danial%20Fakhri%20Bin%20Fakhruddin"> Muhammad Danial Fakhri Bin Fakhruddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Khairul%20Nizam%20in%20Hosnodin"> Muhammad Khairul Nizam in Hosnodin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ezzat%20Hariz%20Bin%20Norhisam"> Muhammad Ezzat Hariz Bin Norhisam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ergonomics is the science of creating and arranging workplaces, products, and systems to increase human performance, comfort, and safety. This study researched ergonomics as a solution for preventing workplace injuries, specifically musculoskeletal disorders, among employers and employees. The method will be used in this project is a literature review which means conducting a study about ergonomics with peer-reviewed journal articles and books. It focuses on employees and employers who are in one company on other departments under the protection of Occupational Safety and Health (OSHA). These solutions include ergonomic assessments, workplace design improvements, effective training and education, and the use of ergonomic tools and equipment. Employers can build workplaces that are safer and more productive by putting these solutions in place, and employees can work comfortably and prevent accidents from bad ergonomics. Overall, the paper highlights how crucial it is to take injury prevention measures and consider ergonomics at work. <p class="card-text"><strong>Keywords:</strong> <a
