    The study was carried out to determine the physical and mechanical properties of composite lumber made from cassava (Mahinot esculenta Crantz) and bamboo (Bambusa vulgaris) in different ratios which is 100% cassava with 0% bamboo, 75% cassava with 25% bamboo, 50% cassava with 50% bamboo, 25% cassava with 75% bamboo and 0% cassava with 100% bamboo. The tests samples for determining the strength properties were divided into two categories namely mechanical testing and physical testing. Basic density of the samples was carried out for physical testing. The lowest basic density was in samples with 100% cassava which is 0.49 g/cm3 and highest in samples with 100% bamboo which is 0.68 g/cm3. Two tests for the mechanical testing are bending test and compression test. In bending test, modulus of elasticity (MOE) and modulus of rupture (MOR) were both highest for samples with 100% bamboo which the reading of MOE was 16794.03 N/mm2 and 122.52 N/mm2 for MOR. Similar to the bending test, compression test is the highest for the samples with 100% bamboo which are 65.58 N/mm2. From statistical analysis, the basic density, static bending can compression strength give significant value at 95% confidence interval.

    Unmanned air vehicles (UAV) have been used for many years and it mainly focus on military purposes. Numerous UAV development have been popular worldwide because the low in development cost, operating cost and ability to provide accurate surveillance information and it is a better option for performing reconnaissance missions in hostile environment. However, in the past years a new type of UAV has appeared that possessed lighter weight and smaller in size and it is categorized as a micro unmanned air vehicle (μ-UAV). Although the non-autonomous ready-to-fly tailless μ-UAV exists among local universities, the development of non-autonomous ready-to-fly tailless μ-UAV is still open to be explored. Thus, this project demonstrates the development of the non-autonomous ready-to-fly tailless μ-UAV named as Neo-Ptero. A special CNC hot wire cutter machine was used in the Neo-Ptero fuselage and wing development in which has evidently produced high accuracy of shapes and geometry based on the CAD design. A 3D printing process was used to produce few parts in the Neo-Ptero μ-UAV model. The model was equipped with on shelves RC components for future flight testing purpose. The actual Neo-Ptero weigh around 1.3kg and has a wingspan of 120.6cm.

    A new innovation has been created which is called AUTOMATIC MEAT SLICING (AMS) MACHINE. The main purpose of the machine creation is to replace the old-style method in slicing the chicken meat to modern method. BABARITTOS DELIGHT supplies Tortillas Wrap to the latest trend of Food & Beverage (F&B) business called Food Truck. The main ingredient of Burritos is slices of boneless chicken meat, where each slice is approximately has to be 5 mm thick. Formerly, the slicing procedure used a normal cutting knife and its production rate was truncated as the demands of the Burritos are going higher by days. This method requires 3 to 4 workers to team up to complete the 30 kg boneless chicken meat to be cut into roughly 5 mm per slice within one and half hour. The AMS machine is predominant to help the company to grow the output of sliced meat and at the same time can reduce the number of workers. The usage of AMS machine is only required one worker for the operation and the output can be up to 30kg per 30mins, which is actually can end up almost 3 times quantity of output and 3 times labor cost-saving. Meanwhile the quality of the sliced meat is much enhanced as most of the slice meat is precisely 5mm thick. The AMS concept design is cutting the meat using several circular cutting blades, where the chicken will be put on the moving conveyor and finally will fall onto the hygienic tray.

    This paper is about the reduction of the overall size of metal blanking sheet that is being used to form a stamping product or car body panel of a car manufacturer in Malaysia. The current blanking sheet produces extra waste which will be recycled and does not contribute to increase productivity but increases inventory cost. The reduction in the blanking sheet size will lead to the reduction of raw material hence reduced the production cost. However, the reduced size of blanking sheet could affect the yield strength of the product. The study of the yield strength and yield improvement of the product are done by simulating stress analysis by using CATIA software. The results show that the new proposed size of the metal blanking sheet provides accuracy of the product dimension as well as maintaining the yield strength of the product and it reduced a significant amount of metal scrap which is nearly 4% of material weight and save around 10% of inventory cost.

    Background: During a given year, almost 30% of the people around the world are affected by mentally ill health. In India, it accounts for about 20%. Caregivers face a lot of strain, ill health, and disrupted family life, with literature suggesting an increasing concern about their ability to cope up. The needs of caregivers of the mentally ill are given low priority in the current health-care setting in India.

    Aim: The aim of the study was to assess the burden of caregivers of mentally ill individuals and their coping mechanisms.

    Methods: A cross-sectional study was employed with a quantitative approach. A convenient sample of 320 caregivers was taken from two private tertiary care centers and one public secondary care center in Udupi taluk. This study was conducted using the Burden Assessment Schedule (BAS) and Brief Cope Scale (BCS). Statistical analysis was done on categorical variables, and they were expressed as frequencies and percentages. Continuous variables were measured using mean and standard deviation. Univariate and multivariate analysis using binomial logistic regression was done. SPSS version 15 was used to analyze the data.

    Results: According to BAS, severe burden accounted for 40.9% and moderate for 59.1%. The highest amount of burden was seen in the areas of physical and mental health, spouse related, and in areas of external support. The BCS showed that the most frequently used coping styles were practicing religion, active coping, and planning.

    Conclusion: This study concluded that caregivers of the mentally ill individuals do undergo a lot of burden. Hence, there is a need to develop strategies that can help them such as providing them with a support structure as well as counseling services.

    Objective: Osteoporosis is usually asymptomatic until the first fracture occurs. The tendency of developing osteoporosis is higher in postmenopausal women. The purpose of the present study was to analyze the knowledge, attitude and practice (KAP) regarding osteoporosis among Allied Health Sciences students in a public university in Malaysia, its associated sociodemographic factors, and association between the KAP. Materials and Methods: This was a cross-sectional study. The participants who were selected using convenience sampling were given a questionnaire that comprised four sections on sociodemographic and KAP regarding osteoporosis. Descriptive statistics, independent t-test, and correlation test were used accordingly to analyze data using SPSS version 20. Results: The total KAP scores were 39.62 (SD=2.87), 35.82 (SD=4.72), and 20.34 (SD=2.86), respectively. There was no significant association between KAP regarding osteoporosis with sexes (p=0.063, p=0.723, and p=0.162, respectively) of the participants, neither between knowledge and attitude with age (p=0.784 and p=0.366, respectively), or year of study (p=0.833 and p=0.468, respectively) of the participants. However, there was a minimal significant negative correlation between practice with age and year of study of the participants (r=-0.230, p=0.017 and r=-0.238, p=0.014, respectively). Finally, there was also a significant fair positive correlation between attitude and practice regarding osteoporosis (r=0.339, p<0.001). Conclusion: The participants in the present study had moderate/fair level of knowledge and attitude but poor practice regarding osteoporosis. Only age and year of study were found to be significantly negatively associated with practice, in addition to the fair positive correlation between attitude and practice. © 2018, AVES Ibrahim KARA.

    Objective: The aim of this study was to determine the treatment given to patients following a low trauma wrist fracture presenting to an Accident and Emergency (A&E) Department at a tertiary private hospital in Malaysia. Methods: The records of patients over the age of 50 attending A&E Department from 2011-2015 with a diagnosis of Colles Vdistal radius/wrist fracture were obtained. Information was extracted for those with a low trauma fracture. Data was analysed using IBM SPSS Statistics version 22.0 for Windows. Results: 191 patients presented with a wrist fracture for the years 2011-2015. 57 of these were due to accidents which left 134 (70.2%) low trauma wrist fractures for analysis. The mean age of the patients was 61.75 ± 10.23 [standard deviation (SD)] years. There were 87 (64.9%) females, and 90 (67.2%) were of Chinese ethnicity. Following the index low trauma wrist fracture, 16/134 (11.9%) were given anti-osteoporotic medication. Of those given treatment, 11/16 (68.8%) were given calcium/Vitamin D/activated Vitamin D and only 5/16 (31.2%) were given active anti-osteoporotic treatment. The median duration of prescribed treatment was one month. There was no significant difference in demographic factors between patients who were treated and not treated with anti-osteoporosis medication. Conclusions: Currently, treatment for osteoporosis following low trauma wrist fractures in Malaysia is inadequate with only 11.9% receiving treatment, and in those who are treated, the median duration of treatment was only one month. This represents a missed opportunity for the prevention of future fractures. © 2018 CIC Edizioni Internazionali s.r.l. All rights reserved.

    Aim: This study was a qualitative study that investigated the exercise prescription method in knee osteoarthritis patients in Malaysia. It purposed to find out the most common and effective method used by physiotherapist in prescribing exercises for knee osteoarthritis patients in Malaysia.
    Method: This study used a self-administered survey questionnaire. The subjects recruited for this study were diagnosed with knee osteoarthritis, age range of between 50 to 80 years old.The methods of delivery were divided into three categories, which include only verbal instructions, verbal instruction together with demonstration and lastly a combination of all three methods including verbal instruction, demonstration and handouts with diagrams.
    Results: The results showed that 52% received their exercise prescription with verbal instruction and together with demonstration, about 43% of them received all three types of methods which included the verbal instruction, demonstration and take home handouts and 5% of them only received verbal instruction. Out of 5% who received verbal instruction alone, only 1% understood the exercises and the remaining 4% did not and 45% out of 52% who received verbal and demonstration method understood the exercises and the remaining 7% did not. 5% who received only verbal instruction did not seem to continue the exercises at home. 52% received verbal instruction together with demonstration, with about 44% of them having continued their exercises but the remaining 8% did not. 43% who received all three methods reported to continue.
    Conclusion: The best method of delivering exercises to knee osteoarthritis patients was proven to be the method with a combination of verbal instruction, demonstration together with a take home handout. This method showed very positive outcome and should be implemented and emphasized more in both the government and private sectors of physiotherapy departments.

    BACKGROUND: This prospective clinical-radiological study was conducted to determine whether the dynamic mobility stress radiographs can predict the postoperative vertebral height restoration, kyphosis correction, and cement volume injected after vertebroplasty.

    METHODS: Patients included had the diagnosis of significant back pain caused by osteoporotic vertebral compression fracture secondary to trivial injury. All the patients underwent routine preoperative sitting lateral spine radiograph, supine stress lateral spine radiograph, and supine anteroposterior spine radiograph. The radiological parameters recorded were anterior vertebral height (AVH), middle vertebral height (MVH), posterior vertebral height (PVH), MVH level below, wedge endplate angle (WEPA), and regional kyphotic angle (RKA). The supine stress versus sitting difference (SSD) for all the above parameters were calculated.

    RESULTS: A total of 28 patients (4 males; 24 females) with the mean age of 75.6 ± 7.7 years were recruited into this study. The mean cement volume injected was 5.5 ± 1.8 ml. There was no difference between supine stress and postoperative radiographs for AVH ( p = 0.507), PVH ( p = 0.913) and WEPA ( p = 0.379). The MVH ( p = 0.026) and RKA ( p = 0.005) were significantly less in the supine stress radiographs compared to postoperative radiographs. There was significant correlation ( p < 0.05) between supine stress and postoperative AVH, MVH, PVH, WEPA, and RKA. The SSD for AVH, PVH, WEPA, and RKA did not have significant correlation with the cement volume ( p > 0.05). Only the SSD-MVH had significant correlation with cement volume, but the correlation was weak ( r = 0.39, p = 0.04).

    CONCLUSIONS: Dynamic mobility stress radiographs can predict the postoperative vertebral height restoration and kyphosis correction after vertebroplasty for thoracolumbar osteoporotic fracture with intravertebral clefts. However, it did not reliably predict the amount of cement volume injected as it was affected by other factors.

    In this day and age, with the ever-growing population and energy demand, we should take the renewable option route in our energy source. We should also keep in mind that said energy should not cause any lasting environmental damage, one of the perfect example being solar energy. A country that is hot and sunny all year long is the perfect contributor to solar energy, case in point, Malaysia. With that in mind Solar Tree is designed and developed to facilitate consumers who need electric power at any place, anytime, anywhere. The objective of this study is to assess a mini project in the likes of Solar Tree that can generate electricity without harming the environment, despite the weather. Intended specifically to be a mini project, it is understandable that electricity generated is limited, with only up to 500W in total. As a trial, two electronic devices were tested, specifically a mobile phone and a laptop, as both devices are used almost every day. The data collected is then tabulated and analysed. It was concluded the solar tree developed proved efficient in charging both devices and will continue to do so given enough sunlight.

    Sustainability is a worldwide objective in balancing the gradual rise of human requirements and the decay of resources. In further aspect, the conceptual paper studies the sustainability performance of new techniques to control sewage contamination in order to prevent foul odors into the habitable space from drainage network, which is important for the healthiness and comfort of living environment. Waste drain pipe is a prominent facility in service engineering development and it is essential in regulating sewage contamination that is commonly obstructed by ungoverned disposal of debris by domestics and commercial buildings. This act is common and consistent in arising disturbance causing the failure of sewage management. This research emphasizes on the innovative establishment of a new controlling method upon sewage contamination known as Black Air Gun (BAG); this indicator is operated based on Perceived Sustainability Performance Indicators (PSPI). This indicator functions to evaluate the impact of BAG upon sewage contamination control. Furthermore, PSPI can acknowledge the sustainability issue of BAG usage in sewage management as a basis for evaluating the impact of BAG towards sewage contamination control. Adopting PSPI in this study will effectively provide a sustainable establishment attained for improvement of people’s quality of life in long term aspects.

    People struggle to name odors [1-4]. This has been attributed to a diminution of olfaction in trade-off to vision [5-10]. This presumption has been challenged recently by data from the hunter-gatherer Jahai who, unlike English speakers, find odors as easy to name as colors [4]. Is the superior olfactory performance among the Jahai because of their ecology (tropical rainforest), their language family (Aslian), or because of their subsistence (they are hunter-gatherers)? We provide novel evidence from the hunter-gatherer Semaq Beri and the non-hunter-gatherer (swidden-horticulturalist) Semelai that subsistence is the critical factor. Semaq Beri and Semelai speakers-who speak closely related languages and live in the tropical rainforest of the Malay Peninsula-took part in a controlled odor- and color-naming experiment. The swidden-horticulturalist Semelai found odors much more difficult to name than colors, replicating the typical Western finding. But for the hunter-gatherer Semaq Beri odor naming was as easy as color naming, suggesting that hunter-gatherer olfactory cognition is special.

    Events with no charged particles produced between the two leading jets are studied in proton-proton collisions at s = 7 TeV . The jets were required to have transverse momentum p T jet > 40 GeV and pseudorapidity 1.5 < | η jet | < 4.7 , and to have values of η jet with opposite signs. The data used for this study were collected with the CMS detector during low-luminosity running at the LHC, and correspond to an integrated luminosity of 8 pb - 1 . Events with no charged particles with p T > 0.2 GeV in the interval - 1 < η < 1 between the jets are observed in excess of calculations that assume no color-singlet exchange. The fraction of events with such a rapidity gap, amounting to 0.5-1% of the selected dijet sample, is measured as a function of the p T of the second-leading jet and of the rapidity separation between the jets. The data are compared to previous measurements at the Tevatron, and to perturbative quantum chromodynamics calculations based on the Balitsky-Fadin-Kuraev-Lipatov evolution equations, including different models of the non-perturbative gap survival probability.

    A search for standard model production of four top quarks ( t t ¯ t t ¯ ) is reported using events containing at least three leptons ( e , μ ) or a same-sign lepton pair. The events are produced in proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC, and the data sample, recorded in 2016, corresponds to an integrated luminosity of 35.9 fb - 1 . Jet multiplicity and flavor are used to enhance signal sensitivity, and dedicated control regions are used to constrain the dominant backgrounds. The observed and expected signal significances are, respectively, 1.6 and 1.0 standard deviations, and the t t ¯ t t ¯ cross section is measured to be 16 . 9 - 11.4 + 13.8 fb , in agreement with next-to-leading-order standard model predictions. These results are also used to constrain the Yukawa coupling between the top quark and the Higgs boson to be less than 2.1 times its expected standard model value at 95% confidence level.

    The problem of constructing such a continuous function is called data fitting. Many times, data given only at discrete points. With interpolation, we seek a function that allows us to approximate f(x) such that functional values between the original data set values may be determined. The process of finding such a polynomial is called interpolation and one of the most important approaches used are Lagrange interpolating formula. In this study, researcher determining the polynomial interpolation by using Lagrange interpolating formula. Then, a mathematical modelling was built by using MATLAB programming to determine the polynomial interpolation for a given points using the Lagrange method. The result of the study showed that the manual calculating and the MATLAB mathematical modelling will give the same answer for evaluated x and graph.

    Diverting waste material from landfill sites has a big implication for the creation of new markets and has environmental benefits through offsetting the need for the extraction of raw materials. Besides, the major attention especially in construction industry is the problem to make natural resources sustainable for three to four decades in future. However, in this study finely glass powder with pozzolanic properties is found to be a partial replacement for cement and can acts as filler in the microstructure of a mortar block. Thus, a study was conducted to see the effects of various proportions of windscreen glass waste powder (WGWP) in determining the degree of water absorption on mortar incorporated with WGWP and to determine the optimum replacement to the ordinary Portland cement (OPC) with WGWP. Several compositions of WGWP (0%, 5%, 10%, 15% and 20% by cement weight) of mortar cube sample were prepared and cured at 7, 28 and 60 days to undergo a water absorption test. From this research, it shows that the use of WGWP was found to be the best features pozzolanic enough to use as a partial replacement for cement and it can reduced the pores of mortar by blocking the large voids in the hydrated cement paste through pozzolanic reaction. In the term of water absorption, the lowest reading was achieved in 15% and it can be said that 15% replacement is the optimum replacement of OPC.
