Morphological and genetic variabilities of Fusarium species isolated from Kenaf

The objectives of this study were to identify the Fusarium species associated with kenaf based on morphological, pathological and genetic characteristics. Twenty isolates of Fusarium were obtained from root, leaf and stem of kenaf in Kuala Terengganu,Malaysia. All Fusarium isolates were identified, and classified into four species such as F. oxysporum, F. proliferatum, F.semitectum and F. solani. Based on pathogenicity test, F. oxysporum was only pathogenic and caused Fusarium wilt disease in kenaf based on disease severity index (DSI), plant height and dry weight of plant. For vegetative compatibility groups (VCGs) study, 217 nitrate non-utilizing (nit) mutants were generated with nit1 was the highest mutants recovered. All the species are genetically diverse reflected from the VCG multiple groups. F. oxysporum isolates were grouped into 5 VCGs,F. proliferatum in 3 VCGs and F. semitectum in 4 VCGs. Fusarium species isolated from kenaf were diverse based on morphology and vegetative compatibility, however only F. oxysporum caused Fusarium wilt disease

Metabolic syndrome and its associated factors in patients with severe mental illness in Malaysia

Background: Mental illness is a huge public health issue. Patients with severe mental illness (SMI) are at risk of developing metabolic syndrome (MetS). Therefore, this cross-sectional study aimed to determine the associations between personal, clinical and lifestyle factors with MetS in patients with SMI. Materials and Methods: 151 patients attending psychiatric outpatient clinics in two government hospitals in Klang Valley participated in this study. The Mini International Neuropsychiatric Interview (MINI) was used to diagnose patients with SMI by a psychiatrist. MetS was defined based on the 2009 Joint Interim Statement (JIS) criteria. Information needed on socio-demographic background, clinical characteristics (types and duration of illness and medication), lifestyle factors (physical activity level, smoking behaviour and alcohol consumption) were collected through a face-to-face interview. Body weight, height, waist circumference, percentage of body fat and blood pressure were measured by the researchers. Blood test results were obtained from the medical records. Result: Nearly half of the respondents (48.3%) had MetS, in which it was higher among males (48.5%), married respondents (61.5%), older age group (66.7%) and schizophrenic patients (50.7%). Overweight (AOR=3.64, 95% CI=1.55-8.58) and obese (AOR=15.06, 95% CI=5.27-43.09) patients were more likely to develop MetS. Moreover, middle-aged and older patients were about 3 times (AOR=3.31, 95% CI=1.38-7.94) and 6 times (AOR=5.65, 95% CI=1.62-19.73), respectively, more likely to develop MetS compared to younger patients. Conclusion: This study demonstrated high prevalence of MetS among patients with SMI. It also highlighted the need of regular assessment of BMI among patients with SMI to prevent MetS

Waste management: a qualitative study exploring the perception of food waste management among the community of Pasir Mas

The purpose of this paper is to examine the 2014 post-flood waste management in affected area. For this purpose, Pasir Mas in Kelantan was chosen as the sample area and interviews were conducted with the residents. The interviews aim to gather information about post-flood waste produced,sources of the waste, actions taken by the residents and related authorities bodies to clear the waste, impact of the waste on their living surroundings and health, and assistance needed to manage the waste. A total of 39 respondents consisted of 20 men and 19 women were selected at random for focus group discussion. These respondents represent persons of age 25 years old and above, local and whose living quarters have been affected by the flood. The large volume of mud left by the flood has been identified by the participants as the main source of the post-flood waste. In addition, good cooperation between government agencies and the residents is important to speed up the waste clearing works.However, residents are in much needed support, awareness and education about the impact of long due waste clearing on their health and living environment

Investigation on dynamic performance of concrete column crumb rubber steel and fiber concrete

In general the Normal Concrete (NC) are by quasi-brittle failure, where, the nearly complete loss of loading capacity, once failure is initiated especially under dynamic loadings. The significance of this study is to improve the damping properties of concrete structure by utilization of the recycled materials from waste tires to be used in concrete as structural materials that improve seismic performance. In this study, the concrete containing 10% of fine crumb rubber and 1 % volume fraction of steel fiber from waste tires is use to investigate the dynamic performance (natural frequency and damping ratio).A small scale column were fabricated from Treated Crumb Rubber and Steel Fiber Concrete (TCRSFC) and NC were cast and cured for 28 days to investigate the dynamic performance. Based on analysis, dynamic modulus, damping ratio and natural frequency of TCRSFC has improved considerably by 5.18%, 109% and 10.94% when compared with NC. The TCRSFC producing concrete with the desired properties as well as to introduce the huge potential as dynamic resistance structure from severe damage especially prevention on catastrophic failure

Evaluation on field performance of vegetable soybean (Glycine max (L.) Merrill) varieties grown at two locations in Malaysia

A study was undertaken to investigate the interaction between varieties and soil environments. The experiments were conducted using randomized complete block design (RCBD) with three replications at two different locations representing two different soil types. The locations were; the mineral soil of International Islamic University Malaysia (IIUM) Glasshouse experimental field and the beach ridges interspersed swales (BRIS) soil of Institute Oceanography and Maritime Studies Research Station (IRS) Kuantan, Pahang. The analysis of variance revealed that location contributed significantly to the variations in the number of pod per plant. While, location had no significant effects on the pod yield, number of seeds per plant and plant height. Significant positive correlation was observed between number of pods and seeds per plant for both locations. Between varieties, variety 1 (AGS190) showed the highest marketable pod yield, number of pods and seeds per plant in both locations. The findings from this study could assist the soybean breeders in varietal development, improvement and selection programme in Malaysia

Quality of life satisfaction among converted Kelantan Chinese Muslims

This article investigates the quality of life of the Kelantan Chinese Muslim community before and after conversion to Islam, focusing on their level of satisfaction in term of economic aspect. This research was carried out using the sequential explanatory mixed method design involving 75 respondents selected for quantitative and five respondents for qualitative. The sampling method adopted was convenience and snowball samplings. The research data was collected using questionnaires and semi-structured interviews. The results revealed that respondents were moderately satisfied before conversion and satisfied after conversion. Besides that, there is no significant difference of quality of life before and after conversion to Islam (F = 0.868, p = 0.355) and it was not influenced by the period of conversion to Islam (F = 0.832, p = 0.589). This analysis indicates numerous respondents are still moderately satisfied in their quality of life even though the average data shows they are satisfied after conversion

Rainfall-Induced Hydraulic Properties for Unsaturated Soil in Klang Valley

Klang Valley area is one of the most landslide-prone areas in Malaysia, especially at Hulu Kelang, Kuala Lumpur. The area has been frequently hit by landslide since 1990s. Soil instability is agreed by researchers occurred due to high precipitation and long duration of rainfall which cause property damage and leading to injury and fatality. Slope failure is also triggered by the antecedent rainfall leads to infiltration of rainwater into soil. Therefore, study of rainwater infiltration is vital to relates soil – water interaction and soil behaviour for varies of rainfall intensities and duration for unsaturated soil. The objective of this paper is to determine and compare soil water characteristic curve (SWCC) which is one of the soil hydraulic parameters for Klang Valley area. Samples were collected to determine the soil hydraulic properties at Hulu Kelang area, Universiti Kebangsaan Malaysia (UKM) and Universiti Pertahanan Nasional Malaysia (UPNM) campuses. SWCC was obtained by pressure plate extractor apparatus experiment and the analysis was performed using Van Genuchten equation. Result of parameters obtained shows significant differences of soil at Hulu Kelang area compared to soils at UKM and UPNM campuses. This research is relevant to supports national slope master plan 2009-2023

Morphological identification of weevil and fungal pathogen associated with sweet potato tuber during storage

Sweet potato is a perishable food crop that is prone to weevil and fungal infection. Development of diseases due to fungal infection will lower its quality, reduce marketable price and sometimes the tubers are unable to sell. Crop losses due to diseases not only have bad implication to farmers, but also give threat to global food production and food security. This study was conducted to identify and document the insect and fungal pathogens associated with sweet potato diseases. For this purpose, infected tubers were collected, incubated and isolated before conducting the pathogenicity test. Ninety sweet potato weevils, Cylas formicarius had emerged and caused extensive damaged to the tuber. Following the sweet potato weevil infestation, four fungal isolates were successfully identified as Fusarium oxysporum (one isolate), Penicillium sp. (one isolate) and Aspergillus sp. (two isolates). All these isolates were pathogenic to sweet potato tubers with different level of diseases severity, ranged from 33.33% to 42.59%. Identification of weevil and fungal pathogen associated with sweet potato diseases is important to help in control strategy to avoid epidemic diseases that may cause loss of economic return. Besides that, farmers should applied integrated pest management control for continuous production of good quality sweet potato tuber
