This aim of this study is to develop a Quick Response (QR) code supported web-based geographical information system (GIS) for facility damage report in university buildings. In general, some academic buildings such as facility management system of Faculty of Architecture, Planning and Surveying (FSPU), Universiti Teknologi MARA (UiTM) encounter a problem of technicians spending more time to manually search for information on damaged equipment. Data processing such as scanning, georeferencing, and digitizing of the building plans were performed to create geodatabase file of the building. QR Codes at the different rooms were then generated by utilising QR Code Generator software. The waterfall or SDLC model was applied to produce a web-based system. This integrated system has facilitated the users with Home and Menus pages that benefit the outsourced parties to directly receive damages reports of the faculty. A survey of user satisfaction was also conducted to evaluate the practicality of the system and the result has shown that the system has the potential to be used by the department of facilities management by integrating with existing database system (e-Aduan) towards a better facility damage management. The proposed web-based system application will assist technicians and staff in managing the facility easier.

One of the most challenging tasks in providing water services is proportion of water loss or known as non-revenue water (NRW). NRW is water supplied to the consumer, but it is lost before it reaches the consumer. The losses of NRW is related with water billing and water produced by local agencies such as Air Selangor. One of the ways to overcome NRW is by changing inaccurate or malfunctioned water meter, but the local department’s water meter still uses the manual method. An innovative geospatial mobile application for water loss meter tracking system was developed at AIR Selangor s, Shah Alam. The main stages used in this study were identifying the problem, designing the app, developing the app and lastly evaluating the app’s performance. Selected officers and contractors of the department agreed with the recommendation made by the authors to develop a digitized system based on the current system. The app has technical capabilities to improve the current system which uses pen and paper to manage water loss via meter system at the site. This geographical information system (GIS)-based application could also update and locate all the coordinates of water meters efficiently so that the contractor can easily find the malfunctioned water meters. The respondents agreed that the design and practical functions developed in the app are relevant in dealing with the water problem.

Characteristics of flow pass a shrouded cylinder were investigated experimentally using uniform and non-uniform hole shrouds. The experiments were performed to compare the effect of hole-uniformity of the perforated shroud on the cylinder lift and drag. The porosity for uniform hole shrouds in triangular and square configurations were set around 0.30, while that for non-uniform hole shrouds were set from 0.25 to 0.37. The diameter ratio between the shroud and the bare cylinder was set at 2.0. The experiment was performed in a wind tunnel at Reynolds Number of 9.345 x 103 based on the bare cylinder diameter and constant incoming air flow speed. Results showed that although all shrouded cylinder models reduced drag significantly in comparison to that of the bare cylinder case, the non-uniform hole shrouds were considerably effective than the uniform hole shrouds. Total drag reduction achieved by the non-uniform hole shrouds of 30% porosity was between 90-95% whereas that of uniform hole was only 55-80% at the same porosity.

In this study, intelligent food packaging in the forms of film and coating were developed based on starch, chitosan and curcumin extracted from turmeric. Solution casting method was applied to develop the film. Both of the film and coating were evaluated and compared by their chemical, physical and biological properties. The film was evaluated in terms of tensile strength measurement, FTIR spectroscopy, antioxidant activity and antimicrobial activity as well as color difference parameters after application on the strawberry. The results obtained showed that the film has a tensile strength of 1.37 MPa, elongation at break of 18.9%, antioxidant activity of 95.65% and high antimicrobial activity as the film had successfully delayed the formation of mould on the strawberry after 5 days of storage. In addition, the stability of both film and coating were evaluated based on their applications on strawberries at two different conditions which are at room temperature and chiller temperature during 5 days storage to identify their potential use as intelligent food packaging. After 5 days, it was found that the film at room temperature had been partially degraded and the coating had caused colour degradation and texture deterioration of the strawberry. In contrast, the film and coating stored at chiller temperature remained the same in terms of physical structure and able to monitor and extend the shelf life of the strawberry. For the evaluation of the film as pH sensing film, the colour of the film changed after 5 days from 53.46 to 48.92 for L*, 26.01 to 22.68 for a* and 42.49 to 44.65 for b* at chiller temperature, while at room temperature, the values of L* changed from 53.96 to 48.96, 25.54 to 20.36 for a* and 46.34 to 44.10 for b*. These showed that the film was able to monitor the freshness of the strawberry by changing its colour in respond to pH changes of the strawberry. The results obtained revealed that both of the film and coating have a greater stability at chiller temperature as compared to storage at room temperature and both have a strong antioxidant activity and strong antimicrobial activity that they delayed the spoilage of the strawberries. Therefore, the film and coating based on starch, chitosan and curcumin can be used to monitor freshness of refrigerated food and have the potential to be used as intelligent food packaging.

Natural fibers from plants are gaining importance and may substitute wood in the production of wood plastic composites (WPC). To ensure continuity of fiber supply and sustainability of WPC industries, fibers of various types could be mixed together to obtain Mix WPC. However, research need to be carried out to identify the contribution of different fiber type collectively to the mechanical properties of Mix natural fiber polymer composite (NFPC). In this study, preliminary work on the use of natural fibre (NF) such as kenaf, sugar palm and pineapple leaf fibers in the preparation of Mix NFPC were carried out. Four different fiber mix samples with different fiber ratio and size were formulated using polypropylene (PP) as the polymer matrix. Montmorrilonite (MMT) filler was added at constant amount for enhancement of composite mechanical properties. Samples were mixed and prepared using a twin screw extruder and mini injection moulding resepectively. Individual fibers and NFPC prepared were characterized using thermogravimetric analyzer (TGA). Tensile, flexural and impact strength of the composites were determined. Generally, it was found that addition of fiber mix at 50% fiber loading enhance the tensile and flexural strength of the various NFPC with minimal exceptions. The impact strength of the composites were comparable to that of blank PP implying that addition of fiber gives additional advantage besides being eco-friendly. It was also found that higher kenaf loading and different size of fiber mix contribute positively to the various strengths measured. In addition to that, composition of individual fibers also contribute to the mechanical properties of the NFPCs.

The effect of different drying methods using spray dryer and rotary evaporator towards the physico-chemical properties and thermal stability of powdered tannin extractives from Rhizophora Mucronata bark was investigated. Prior to spray drying at 130°C and rotary evaporating at 80°C, tannin was extracted using water-based boiling extraction at temperature ranging from 80 to 90°C. Powdered tannin extractives obtained by spray dryer decomposed at higher temperature (at 270°C) than those using rotary evaporator (at 210°C). The powdered tannin extractives from spray dryer was higher in thermal stability due to the high crystallinity peak appeared from X-ray Powder Diffraction (XRD) analysis. Condensed and hydrolysable tannins were also quantified using Reverse-phase High Performance Liquid Chromatography (RP-HPLC) for both methods. Powdered tannins extractives using spray dryer contained 27.8% condensed tannins and 0.001% hydrolysable tannins, in which the condensed tannins are slightly higher in concentration than those formed using rotary evaporator which was 26.5%. The findings revealed that the used of spray dryer is more beneficial to obtain a stronger thermal stability and a higher concentration of powdered Rhizophora Mucronata bark tannins extractives.

Published: November 2019

The human lower limb is a major part of the human body that is exposed to high joint load during daily activities. Different lifestyles and cultural activities can affect the loading condition generated at the joint during motion. For instance, deep squatting is more frequently performed by Asians compared to Europeans e.g. kneeing on tatami among Japanese and sitting position during prayer among Muslims. The aim of this research is to determine the joint load of the human lower limb during the squat lifting movement by using inverse dynamics of 2-dimensional (2D) human lower limb model. The 2D inverse dynamics modelling was used to describe and compute all the joint force reactions from the known ground reaction and lower limb kinematics. In this study, 2D human lower limb model was analysed during the squat lifting movement. Inverse dynamics computation was performed using MATLAB programming based on Newton-Euler equations to determine the joint forces and moments. The joint loads at ankle, knee and hip joints for every knee flexion angle were obtained and the maximum forces at the ankle, knee and hip were 613.9, 614.1 and 596.1 N, respectively.

Ballast is the weakest among all of the railway track components due to its latent dynamic shifting and variation of stiffness along and across the track. Sharp Angular shape of the ballast components hinders evenly distribution of loads from sleeper to ballast, which in turn causes the sleepers to deteriorate over time resulting in higher frequency of railway track maintenance. Previous studies have shown that having an under-sleeper pad (USP) in between sleeper and ballast increases the contact area between them significantly. This by itself reduces the long-term damage on sleepers by a substantial amount. However, concrete sleeper is subjected to cracking due to excessive dynamic load from rail wheels. This paper intends to numerically evaluate whether the cracking of concrete sleepers gets reduced due to installing of USPs in the railway track system. The foremost reason behind cracking of concrete sleepers is the induced dynamic loads due to track irregularities and imperfect wheel rail contact. The most affected portion is at the bottom of the rail seat location of sleeper. Thus, two finite element models (one without USP and one with a 20mm thick USP attached at sleeper bottom) were analyzed while incorporating the concrete damage plasticity in the sleepers’ material. Results have shown better performance of concrete sleepers with USPs. Sleeper pads have shown a tendency to minimize excessive stress developed within naked concrete sleepers. Substantial advantage of using USPs in terms of damage reduction among sleepers were also perceived during conducting this analysis. Consequential reduction of crack formation was observed after installation of USPs.

Aquilaria malaccensis Lam. and Aquilaria subintegra Ding Hou belong to the family of Thymelaeaceae which is commonly known as gaharu or agarwood. It is a commercially important tree and identified as a potential aromatic plant. The overwhelming responses in the lodging sector reduce gaharu species in the forest. Mass propagation through plant tissue culture technology will substitute this problem. The present study was conducted to investigate the embryogenic callus induction between these two species. The most optimum sterilization method for both species was sodium hypochlorite 5.0% which gave the highest percentage of aseptic culture (95%) with the absence of tissue browning. The leaves of both species were cultured on Murashige and Skoog, (1962) (MS) media supplemented with combination of various concentrations of 6-benzylaminopurine (BAP) (0.5, 1.0, 2.0 and 2.5 mg/L) and 2,4-dichlorophenoxyacetic acid (2, 4-D) (0.5, 1.0, 1.5 and 2.0 mg/L) and kept under dark condition. The explants produced embryogenic, white and compact callus at the end cut of the explants after two weeks of culture in all treatments. The highest frequency of embryogenic callus formation was observed in explants cultured on 2.0 mg/L BAP and 0.5 mg/L 2,4-D for both species. From the present study, the optimum sterilization technique and embryogenic callus induction for A. malaccensis Lam. and A. subintegra were established.

The brain tumor (BT) has turn into a chief hazard to life in many humans. With the advances in medicine and technology, early tumor detection may pay a way for treating it in an early phase and thereby reducing the death rates. MRI imaging has a significant role in imaging the BT. Neurologist base the treatment of BT on the type, location, and also size of the tumor and hence proper segmentation of the tumor region has become essential. Here, an efficient segmentation algorithm is proposed, is centered on using the Sobel edge detection mechanism and the classification of the tumor region centered on the features extorted as of the segmented images are performed. The brain MRI images from a database which contain normal and also abnormal cases. These images are stripped from the skull by utilizing the morphological operations like morphological opening along with closing. Following this, segmentation is executed and finally, features are extorted as well presented to the classifier where the classification is executed. The segmentations algorithm is estimated and also the outcome are contrasted to the other prevailing algorithms say Kmeans and SVM (Support Vectors Machine) and the classification algorithm is weighted against that of the existent classification algorithm like PNN (probabilistic neural network) and ANN (Artificial Neural Network). Thus the proposed algorithms are confirmed to be superior to the other algorithms used in BT segmentations and classification.

Protection of client’s data in cloud is an important aspect which a cloud service provider assures to a cloud user. Though using high end sophisticated methods security is provided to client’s data in cloud. Besides this theft of data has emerged as one of the common and major issue and which has grown to a big challenge even today also. In this paper we have proposed a unique algorithm which provides security for the data in different forms stored in cloud. In this paper we used a unique algorithm “SKM” by combining EOBE methods where encryption, obfuscation followed by binary encryption is effectively used to reach out the required target task. The data may be either, numeric, non-numeric or binary data related to image files. Depending on kind of data the required process is initiated in order to convert the data in a safe form. From the suggested algorithm a reduced timing with respect to encryption, decryption was achieved. Though the security concept in cloud is a bit difficult to deal, our proposed algorithm has achieved maximum security level among the existing ones. Using industrial tool the observed results are compared with the existing and popular methods of security algorithms. This creates a confidence among several cloud users and small scale business organization to move and enhance their belief on security of data in cloud.

The purpose of the study is to nd out the effects of yogic practices and physical exercises on Low Density
Lipoprotein of urban obese boys students. Forty ve healthy, untrained students were selected from
various schools in Madurai. The subject's age ranged from 13 to 15 years. The chose subjects were isolated into three gatherings
with fteen subjects in each gathering. The training periods of experimental groups were six weeks, three alternative days per
week with duration of 60 minutes. Control group did not undergo any training programme rather than their routine work. Pre
tests were conducted for all the 45 subjects on selected Low Density Lipoprotein variable. After the experimental period of six
weeks post test were conducted immediately. To study the effect of yogic practices group and physical exercises training group
along with control group and to nd out the signicant mean differences among them, the analysis of covariance (ANCOVA)
technique were used. Scheffe's test was pursued as a post hoc test to gure out which of the matched methods distinction was
noteworthy. The 0.05 level of condence was xed to test the level of signicance which was considered as an appropriate. The
results of the study were concluded that there was signicant improvement in selected variable.

Background: Facial Injury Severity Severity Score (FISS) has been used to assess the severity of facial
injuries. However, FISS scores as a useful predictor of length of stay and changes between FISS scores
and injuries to other parts of the body have not evaluated. In this study, we want to know the relationship between FISS score as
the clinical assessment of maxillofacial trauma with the length of stay, the need for surgery, and the involvement of other
specialist elds.
Method: This research was conducted using analytical research through a retrospective approach by looking at the medical
records of patients who suffered maxillofacial trauma at H. Adam Malik General Hospital Medan from June to August 2019.
Result : From a total of 43 patients included in the study, there were 22 mandibular fractures, with mandibular angulus (29.0%),
parasymphysis (22.4%), and mandibular corpus (21.5%). Thirty subjects (69.8%) needed surgery, and xation of the fracture
and subjects without intervention were 13 (30.2%). Patients who needed surgical intervention, the average time needed for
hospitalization was 10.98 + 7.72 days (p = 0.007). The most collaboration found with neurosurgeons specialists, 39.53% of
subjects who performed the surgery. A total of 55.8% of surgeries performed by a single operator from the plastic surgery
department. Relationship between the length of stay with FISS, obtained for FISS> 3 (OR 14.37) (p = 0.01), meaning that
patients with FISS> 3 are likely to stay longer for 14 times. Subsequent results related to the need for surgery obtained
signicant results (OR = 8.26, p = 0.026). signicant (p = 0.059).
Conclusion: A FISS score signicantly affects the length of stay for a maxillofacial trauma patient. FISS score also affects the
involvement of other specialists in maxillofacial trauma patients but not statistically signicant.

Mild steel is the most extensively used carbon steel for numerous industrial applications, where it is exposed to various service environments containing acids, bases and salt solutions. From industrial point of view, plastic deformation and heat treatment are among the essential manufacturing steps in mild steel processing and these steps can implicate its corrosion behaviour. This work investigated the effect of cold plastic deformation and subsequent high temperature heat treatment on the microstructure and corrosion behaviour of mild steel in two different concentrations (0.5M and 1.0M) of sulphuric acid (H2SO4), using the weight loss method. Mild steel samples were cold pressed to thickness reduction of 20%, 40% and 50% and subsequently heat treated at 700oC and 900°C and then air-cooled. The test duration lasted for 25 days and the weight loss measurements were taken at intervals of 5 days. It was observed that corrosion rates of the samples were generally higher in the 1.0M than in 0.5M acid solution. The as-received and heat-treated mild steel samples exhibited higher corrosion rates than the cold-pressed and heat-treated samples. The results indicated strongly that cold working accompanied by heat treatment improves corrosion resistance of mild steel in acidic media.
