    Recent evidence has exhibited dietary influence on the manifestation of depressive-like behaviour induced by stressor tasks. The present study examined the effects of Tualang honey supplement administered with the goal of preventing or attenuating the occurrence of depressive-like behaviour in male rats subjected to noise stress. Forty-eight adult male rats were randomly divided into the following groups: i) nonstressed with placebo, ii) nonstressed with honey, iii) stressed with placebo, and iv) stressed with honey. Tualang honey (200 mg/kg body weight) was administered for 28 days. Stressed rats were subjected to loud noise 100 dB(A) 4 hours daily for 14 days. Forced swimming test was performed to evaluate depressive-like behaviour. Stressed control rats displayed significant increase in depressive-like behaviour, serum adrenocorticotropic hormone (ACTH), corticosterone, and brain oxidative stress markers levels, with significant decrease in antioxidant enzymes activities and total antioxidant status. Honey supplementation successfully counteracted the stress effects whereby the honey treated rats exhibited significant decrease in depressive-like behaviour and levels of ACTH, corticosterone, and oxidative stress markers, with significant increase in antioxidant enzymes activities and total antioxidant status. In conclusion, Tualang honey mediated antidepressant-like effects in stressed rats, possibly acting via restoration of hypothalamic-pituitary-adrenal axis through its antioxidant properties.

    This paper aims to analyze the distinction of premium setting rates by taking into account the risk
    taken by conventional and Family Takaful. This study employed the Net Single and Annual Level
    Premium formula, and the data were analyzed using a numerical simulation. We found that the
    conventional and Takaful insurance systems utilize similar methods in the calculation of insurance
    premium when considering pure risk faced by the participant or insured. However, both systems have
    their own unique characteristics. The conventional and Family Takaful utilize historical data, such as
    mortality rate, expected return rate, expected costs and expected amount of claims. The conventional
    insurance is calculated to mitigate or minimize the risk of the insurance company against an amount of
    claim faced in the future as long as the insurance is enforced until the contract ends. On the other
    hand, the Family Takaful is intended to share fair value among participants in determining
    benevolence through Tabarru premium. Every participant must pay for Tabarru premium to support
    one another so that there is sufficient amount to cover unexpected claims among them and to uphold
    mutual fund as evidence for the sense of mutual co-operation and brotherhood among participants.

    In the current study, a total of 86 soccer’s players with mean age of 14 years drawn from Terengganu soccer academy were tested in performing 10 parameters aiming at determining the performance of those players based on assessing the contribution of each activity and its corresponding significant level. The 10 performance related parameters involved anthropometry (BMI), fitness test (agility, coordination, muscular endurance (push and sit up), power, YoYo level), and football skill test (dribbling with ball, dribbling without ball and juggling). All the parameters testing is carried out based on international standard and performed by well-trained staff. The Pearson correlation analysis was used to achieve the objective in this study. Result shows a positive correlation between the two types of muscular parameters; the power is influenced by BMI and coordination; the specific football tests are highly impacted by the power and agility. The coefficient of determination R^2 and the significance level p-values show that the parameters that can be significantly considered are the anthropometric BMI (0.020), agility (0.025), muscular endurance (0.039 and 0.043), power (0.039), special football test without the ball (0.041), and juggling (0.046). The coordination, YoYo, football special test with the ball were not found to be significantly accounted for preparing the young players to achieve the required performance. Based on the results of the coefficient of determination and the significance p-values of the parameters, a model was proposed to determine the highest and lowest parameters that play important roles in the selection of young players.

    Extra virgin olive oil (EVOO) is categorized as expensive oil due to high-quality nutritional value. Unfortunately, EVOO is easily adulterated with other low-quality edible oils. Therefore, this study was done to differentiate and analyze the adulteration of EVOO with other edible oils using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy. The study was used several edible oils included canola oil, corn oil, sunflower oil, and soybean oil as an adulterant for EVOO. The adulterant EVOO samples were prepared by mixing with dissimilar concentrations of the solely edible oils (20 %, 40 %, 60 % and 80 % (v/v)). The main functional groups of EVOO and other edible oils are O-H, C-H, C=C and C=O groups were assigned around 3500 cm-1, 2925 cm-1, 3006 cm-1 and 1745 cm-1 wavenumbers, respectively. From the comparison of EVOO and other adulterant edibles oil spectra, it showed that the EVOO has the lowest absorbance intensity at around 3006 cm-1 represented double bond which is closely related to the composition of oil sample. The adulteration of EVOO was evaluated by analysing the changes in the absorbance based on the linear regression analysis graph of the bands at 3006 and 2925 cm-1 and the limit of detection (LOD) was measured. The graph of A3008/A2925 with good relative coefficients (R2) and lower LOD is more favourable than the linear regression graph of A3006 versus percentage of edible oils added in EVOO. This study showed that ATR-FTIR spectroscopy is a convenient tool for analysing the adulteration of EVOO.

    The hydrology hydraulic model is established to assess environmental information on hydrology which
    can be used to investigate causes of various environmental problems at the river and natural lake
    catchment. This study reports on sediment concentrations at a river using a gravimetric method to
    investigate the hydrology system at a lake catchment. The measurement was carried out at the
    upstream, midstream, and downstream stations on the river in normal, rainy and post-rainy seasons.
    The stations are located along the Chini River, which are connected to a catchment lake (located at
    latitude 3°26’36.41”E-3°27’03.26”E and longitude 102°54’31.94”N-102°53’35.49”N). From the
    measurements, it is estimated that on average 787.621 tonne/km2 of sediment is transferred into the
    natural lake via Chini River annually. The correlation of statistical analysis between the sediment load
    and discharge study was very significant (R2 = 0.980). There is a linear relation between the area of
    the catchment and sediment load of the connecting river as supported by other studies in Malaysia.
    The outcome of the study suggests that the high sedimentation is due to land use activity, existence of
    the dam at the downstream of Chini River that traps the sediment, reverse flow from the Pahang River
    into Chini River and riverbank erosion factors. From this study, the sediment control steps are
    suggested such as creating conservation partially at the lake catchment, modifying the dam system,
    riverbank erosion control, and application of “Monkey Cheek” system. These sediment control steps
    may help to clean up the high suspended sediment at the whole lake system area, hence solving and
    mitigating the environmental problems in the natural lake catchment.

    The current and escalating extent of soil degradation, water scarcity and environmental concern
    plaguing agricultural productivity, demands re-assessing the direction of food production. Aquaponics
    is a concept relatively new to modern food production methods and can contribute to food security.
    This study was conducted to establish sustainable aquaculture systems that maximize benefits and
    minimize the accumulation of detrimental compounds and other types of negative impacts on both
    natural and social environments. This study carried out at an average inflow rate of 1.28 m/day to
    evaluate the operation of the aquaponics recirculation system (ARS) on nutrients removal and growth
    and yield of African catfish as well as water spinach. A special design of ARS was used to provide
    nitrification of fishery wastewater, where the combination of sands and gravels in hydroponics trough,
    providing both surfaces for biofuel development and cultivation area for plants. Removal efficiencies
    of 5-day biochemical oxygen demand (BOD5), total suspended solids (TSS), total ammonia nitrogen
    (TAN), nitrite-nitrogen (NO2-N), nitrate-nitrogen (NO3-N), and orthophosphate (PO4
    3-
    ) were 82%, 89%,
    93%, 94%, 81%, and 80%, respectively. The feed conversion ratio (FCR) and specific growth rate
    (SGR) of African catfish were 1.08 and 3.34% day-1
    , respectively. The average water spinach
    production was 3.56 kg per m2
    . This study showed that ARS is a method of producing crop along with
    a healthy protein source and among the best alternatives for achieving economic and environmental
    sustainability.

    The importance of rapid ambulance response to emergency medical crises is undeniable. An early
    access to advanced care is crucial to saving a life. Modern computerised call centre and the hospitalbased ambulance services are believed to enhance the quality of service delivery. However, whether
    it will further reduce the ambulance response time is still debatable. A cross-sectional study was
    conducted in June 2012 until July 2012 at three selected tertiary hospitals in Malaysia. The
    ambulance response time was expressed in a median and interquartile range (IQR) and MannWhitney U test was used to determine the associations between types of ambulance and
    computerised call centre system versus voice only. Wilcoxon Rank Sign Test was used to assess
    the significance of means difference. A hospital-based ambulance had the median time of 0.19
    minutes while community-based ambulance had the median time of 0.20 minutes (The Z score -
    0.916, p-value - 0.360). The hospital with computer call centre had the median time of 0.19 minutes
    while hospital without computer call centre had the median of 0.20 minutes (The Z score - 0.816, P
    value - 0.414).The response time of hospital-based ambulance equipped with computerised call
    centre system was comparable in three selected tertiary hospitals in Malaysia.

    In this work, a new model for federation data grid system called Sub-Grid-Federation was designed to
    improve access latency by accessing data from the nearest possible sites. The strategy in optimising
    data access was based on the process of searching into the area identified as ‘Network Core Area’
    (NCA). The performance of access latency in Sub-Grid-Federation was tested based on the
    mathematical proving and simulated using OptorSim simulator. Four case studies were carried out and
    tested in Optimal Downloading Replication Strategy (ODRS) and the Sub-Grid-Federation. The results
    show that Sub-Grid-Federation is 20% better in terms of access latency and 21% better in terms of
    reducing remotes sites access compared to ODRS. The results indicate that the Sub-Grid-Federation
    is a better alternative for the implementation of collaboration and data sharing in data grid system.

    This paper proposes the use of bootstrap, robust and fuzzy multiple linear regressions method in
    handling general insurance in order to get improved results. The main objective of bootstrapping is to
    estimate the distribution of an estimator or test statistic by resampling one's data or a model estimated
    from the data under conditions that hold in a wide variety of econometric applications. In addition,
    bootstrap also provides approximations to distributions of statistics, coverage probabilities of confidence
    intervals, and rejection probabilities of hypothesis tests that produce accurate results. In this paper, we
    emphasize the combining and modelling using bootstrapping, robust and fuzzy regression methodology.
    The results show that alternative methods produce better results than multiple linear regressions (MLR)
    model.

    There are several types of grating, such as platform, bridge decks and filters. In design process, there
    are several important terms that have to be prioritised; engineering design, strength to weight ratio, cost,
    maintainability, reparability etcetera. Advanced materials, such as composite materials offer great
    strength to weight ratio and high mechanical properties for grating fabrication. Furthermore the
    reparability and maintenance problems could be solved as it is anti corrosion and the long service life
    attribute of composite makes it a great design material for replacement of conventional steel or
    aluminium. Bio composites, such as bamboo and coir fiber yield advantage in terms of less cost and
    abundance availability compared to commercial unidirectional composite materials, such as glass fiber
    reinforced polymer (GFRP) and carbon fiber reinforced polymer (CFRP) which is considerably
    expensive yet possess higher mechanical properties. This papers presents a conceptual design of
    grating design utilizing bamboo composite as material. Pugh method has been chosen as design criteria
    selection matrix in finalizing the design of industrial grating for scaffolding (Pugh, 1991).

    Nanofiltration membranes technology commonly used for wastewater treatment especially
    wastewater containing charged and/or uncharged species. Commonly, textile wastewater
    possesses high chemical oxygen demand (COD) and non-biodegradable compounds such as
    pigments and dyes which lead to environmental hazard and serious health problem. Therefore, the
    objective of this study was to investigate the effects of hydrophilic surfactant on the preparation and
    performance of Active Nanofiltration (ANF) membrane. The polymeric ANF membranes were
    prepared via dry/wet phase inversion technique by immersion precipitation process. The
    Cetyletrimethylammonium bromide (CTAB) as cationic surfactant was added in casting solution at
    concentrations from 0 to 2.5 wt%. The synthesized membrane performance was evaluated in terms
    of pure water permeation (PWP) and dye rejection. The experimental data showed that the
    membrane demonstrated good increment of PWP ranging from 0.27 to 10.28 L/m2
    h at applied
    pressure from 100 to 500kPa, respectively. Meanwhile, the ANF membranes achieved high
    removal of Methyl Blue and Reactive Black 5 dye up to 99.5% and 91.6%, respectively.

    The purpose of this study is to determine spatial pattern recognition of school performance based on
    children’s anthropometric and motor skills component. This study involved 94 primary schools with a
    total 2237 male students aged 7.30±0.28 years in Pahang, Malaysia. The parameters of anthropometric
    (weight and height) and motor component included lower muscular power (standing broad jump),
    flexibility (sit and reach), coordination (hand wall toss) and speed (20 meter run) were selected. Cluster
    Analysis (CA) and Discriminant Analysis (DA) under Multivariate Method and technique of Kriging
    Interpolation in Geographic Interpolation Software (GIS) were used. CA revealed two clusters of school
    performance. There are a total 34 high performance schools (HPS) and 60 low performance schools
    (LPS). Then, the assigned groups were treated as independent variable (IV) while anthropometric and
    motor parameters were treated as dependent variable (DV) in DA. Standard mode of DA obtained
    95.74% correctness of classification matrix with three discriminated variables (height, standing broad
    jump and 20 meter run) out of six variables. Meanwhile, forward and backward stepwise mode of DA
    discriminated only one (standing broad jump) out of six variables with 96.81% of classification
    correctness. The map output of Kriging interpolation has shown graphically the pattern of discriminated
    variables that greatly influence school performance. It exposed the ability of children motor skills
    development in particular region is higher than another region.

    The study attempts to use multivariate analysis to evaluate the profile of male player for developments of Long-Term Talent in Sports (LT-TiS) model based on anthropometric and motor fitness components. Data of anthropometric and motor fitness included power, flexibility, coordination and speed were obtained from 2019 respondents aged 7.32±0.52 year. Data interpretations were carried out using multivariate analysis of Principle Components Analysis (PCA) and Discriminant analysis (DA). The adequacy of sampling has been measured using Bartletts tests on sphericity and Kaiser-Meyer-Olkin (KMO) has been used, with this conformance of running the Principal Component Analysis (PCA). Then, Discriminant Analysis (DA) were used to validate the correctness of group classification by LT-TiS model. Then, Discriminant Analysis (DA) were used to validate the correctness of group classification by LT-TiS. As a result, two factors with eigenvalues greater than 1 were extracted which accounted for 55.00% of the variations present in the original variables was found. The two factors were used to obtain the factor score coefficients explained by 27.86% and 27.21% of the variations in player performance respectively. Factor 1 revealed high factor loading on motor fitness compared to factor 2 as it was significantly related to anthropometrics. A model was obtained using standardized coefficient of factor 1. Three clusters of performance were shaped in view by categorizing; LT−TiS≥65%, 40%≤LT−TiS
