Purpose: This study intends to explore the knowledge distribution in immigrant entrepreneurship in a host country Malaysia. In Malaysia, most immigrants are workers who later started their own businesses. They have a higher tendency to engage in entrepreneurial activities thus knowledge distribution from previous employment is necessary. Research design, data and methodology: This qualitative study using in-depth interview approach was carried out with five immigrant entrepreneurs from Bangladesh conducting business in Malaysia. The data were gathered and analysed using thematic analysis facilitated by ATLAS.ti software. Results: The findings provide useful insights on the significance of knowledge obtained during immigrant entrepreneurs’ former employment in the host country, enabling them to identify the needed resources quickly to launch a successful business in a host country. Conclusions: This study contributes to the Knowledge Spillover Theory of Entrepreneurship specifically in the context of immigrant entrepreneurship who have former employment in the same business sector and a proposition is developed. For practicality, the findings provide some insights for immigrants who want to start businesses in the host country which allow them to identify and exploit entrepreneurial opportunities due to knowledge distribution at their former employment in the host country later facilitates successful business establishment there.

Melioidosis is an infection caused by Burkholderia pseudomallei and it represents one of the most common infectious diseases in zoo and farm animals giving rise to high mortality, leading to biological diversity loss. We use the bacteriological and biochemical methods such as culture, biochemical test, Gram-staining and oxidase test to examine the presence of B. pseudomallei in 50 soils treated and non-treated with quicklime powder collected from Bukit Merah Orang Utan Island, (BMOUI), Perak, Malaysia. We observed mixed bacterial colony growth with various colony morphologies. Six of the isolates labelled as P2(25), P5(2), P5(3), P5(5), P6(1), and P6(6)2 showed pinkish purple colour with wrinkled characteristics similar to B. pseudomallei colony morphology after incubation for 48 h. The results showed that all putative soil-isolated organisms were Gram-negative bacteria, positive for oxidase test and negative for catalase test. In the VITEK® ID system and PCR sequencing analysis, no B. pseudomallei was identified. All six putative organisms were identified as in B. cepacia complex i.e.: B. stagnalis (four cases), B. contaminans (one) and B. multivorans (one). These preliminary findings demonstrate that a few species of B. cepacia group were successfully isolated from the soil of BMOUI using selective media for B. pseudomallei.

Comparing the effects of sodium tripolyphosphate (STPP) concentrations of 0.2% and 0.4% on beef semitendinosus is the objective of the current investigation. The samples were cooked at varied temperatures (45+60℃ and 45+70℃) and times (1.5+1.5 h and 3+3 h) using staged cooking. The colour properties, cooking loss, water retention, shear force, water-holding capacity, sarcoplasmic, and myofibrillar solubility, and total collagen were investigated. The cooking time and temperature affected the water-holding capacity, cooking loss, CIE L*, CIE a*, CIE b*, myofibrillar, and sarcoplasmic solubility, with lower temperature and short time having the lower detrimental effect. However, the significant effect can be intensified after the addition of STPP with higher water-holding capacity and tender meat obtained with 0.4% phosphate concentration at any cooking conditions. The STPP lowered the collagen content and increased the protein solubility of myofibrillar and sarcoplasmic, which this degradation is used as a good indicator of tenderness.

Influence of Thermal Conductivity on the Thermal Behavior of Intermediate-Temperature Solid Oxide Fuel Cells

Aman, Nurul Ashikin Mohd Nazrul,Muchtar, Andanastuti,Rosli, Masli Irwan,Baharuddin, Nurul Akidah,Somalu, Mahendra Rao,Kalib, Noor Shieela The Korean Electrochemical Society 2020 Journal of electrochemical science and technology Vol.11 No.2

Solid oxide fuel cells (SOFCs) are among one of the promising technologies for efficient and clean energy. SOFCs offer several advantages over other types of fuel cells under relatively high temperatures (600℃ to 800℃). However, the thermal behavior of SOFC stacks at high operating temperatures is a serious issue in SOFC development because it can be associated with detrimental thermal stresses on the life span of the stacks. The thermal behavior of SOFC stacks can be influenced by operating or material properties. Therefore, this work aims to investigate the effects of the thermal conductivity of each component (anode, cathode, and electrolyte) on the thermal behavior of samarium-doped ceria-based SOFCs at intermediate temperatures. Computational fluid dynamics is used to simulate SOFC operation at 600℃. The temperature distributions and gradients of a single cell at 0.7 V under different thermal conductivity values are analyzed and discussed to determine their relationship. Simulations reveal that the influence of thermal conductivity is more remarkable for the anode and electrolyte than for the cathode. Increasing the thermal conductivity of the anode by 50% results in a 23% drop in the maximum thermal gradients. The results for the electrolyte are subtle, with a ~67% reduction in thermal conductivity that only results in an 8% reduction in the maximum temperature gradient. The effect of thermal conductivity on temperature gradient is important because it can be used to predict thermal stress generation.

Nurul Hikmah Harun,Abdi Wira Septama,WaAhmadn Amir Nizam Wan,Rapeah Suppian 한국생약학회 2019 Natural Product Sciences Vol.25 No.2

Centella asiatica (Linn.) Urban (Umbelliferae) which is also known as ‘pegaga’ is highly consumed and eaten raw as ‘ulam’ in Malaysia. C. asiatica is used in traditional medicines to treat various health conditions such as rheumatism, inflammation, syphilis, skin diseases and diarrhoea. Various reports exhibited that the crude extracts and isolated bioactive compounds of C. asiatica possessed a broad range of pharmacological activities such as anti-oxidant, anti-diabetic, anti-tumor, wound healing, anti-microbial, anti-inflammatory, immunomodulatory, hepatoprotective and memory enhancing properties. The pharmacological validation on anti-microbial and immunomodulatory of C. asiatica is very limited and several existence review papers related for this plant had not been focused for both activities. This review therefore attempts to combine the existing literature to offer immense scope for researchers engaged in validation of the traditional claims and bioactivities of this plant related with anti-microbial and immunomodulatory potential.

Kelulut honey (KH) is a natural product-derived food produced by stingless bees of Trigona or Meliponine species. Several studies have shown that the geographical origin of honey significantly affects its pharmacological properties. Thus, this study aims to characterise the pharmacological properties of KH harvested from different geographical locations. The total phenolic content (TPC), antioxidant levels, cytotoxic, and anti-inflammatory activities of pure KH harvested from three different locations (Sarawak, Pahang and Selangor) were compared. Among the samples, KH harvested from Selangor exhibited the highest TPC, antioxidant levels, and cytotoxic activity against MDA-MB-231 and MCF-7 cells, followed by KH harvested from Sarawak and Pahang. The IC 50 of MCF-7 cells treated with KH harvested from Selangor was at least 2-fold lower than the IC 50 of MDA-MB-231 cells, suggesting that KH is more cytotoxic to oestrogen receptor (ER)- and progesterone receptor (PR)-positive (MCF-7) compared to triple-negative (MDA-MB-231) breast cancer cells. Two non-cytotoxic concentrations (1% and 0.5%; v/v) were selected for the anti-inflammatory assay using lipopolysaccharide (LPS)-induced RAW 264.7 cells. KH harvested from Selangor and Pahang (at a concentration of 1%; v/v) significantly inhibited nitric oxide (NO) production in LPS-induced RAW 264.7 cells compared to control cells. These findings provide evidence that the geographical origin of KH may indeed influence its pharmacological properties. Our data suggest that KH harvested from Selangor has a better quality compared to KH harvested from Pahang and Sarawak based on its high TPC, antioxidant levels and anti-inflammatory activity. Furthermore, it exhibits in vitro anticancer potential in breast cancer cell lines.

Nurul Hayati Abdul Halim,Che Hassan Che Haron,Jaharah Abdul Ghani 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.21 No.7

Recent trends in metal cutting shows the increasing of demand at the global stage for the application of eco-friendly machining approaches in order to eliminate the adverse effects of conventional cutting fluids. Thus, this experimental work was conducted to evaluate the performance of sustainable cooling techniques of cryogenic carbon dioxide (CO2), Minimum Quantity Lubrication (MQL), cryogenic liquid nitrogen (LN2) and dry cutting on machinability of Inconel 718. For the cryogenic CO2 approach, a new concept of cryogenic cooling technique was introduced for efficient and consistent cooling performance. The findings displayed cryogenic CO2 as a promising coolant since it resulted in slower tool wear rate compared to cryogenic LN2 and dry cutting, while being more effective in decreasing cutting forces and surface roughness compared to other approaches. Its adequate and consistent cooling efficiently disperses the generated heat and creates an ideal cutting condition for the tool and workpiece to interact with each another during cutting. In contrast to MQL cutting, the usefulness of CO 2 was supplanted due to the resulting shorter tool life. As such, the MQL approach is preferred as it extends the tool life longer by 67.2% with the maximum volume of material removal as compared to cryogenic CO2. Its lubrication impact shows effectiveness in diminishing the tool wear rate than the cooling effect by the cryogenic CO2. However, from the viewpoint of sustainability, MQL could be less preferable due to unpleasant odour and settling of MQL mist around the cutting area.

This paper presents an analysis of the received signal strength indicator (RSSI) from the radio frequency signals for human identifi cation in an indoor wireless sensor network (WSN). Instead of using closed-circuit television as the existing security platform, this indoor safety system was improved with a convenient, cheap, and low-power solution. The system was developed using 20 of ESP8266-12F Wi-Fi modules transmitters and another 2 of ESP8266-12F as the access points located in 3 m × 3 m area of interest. With a suitable coordinate of sensor nodes, a WSN telemetry could be established to minimize the blind spot area and limit the movement of the intruder with a minimum area of 0.2 m 2 . The RSSI measurement was repeatedly conducted for three diff erent conditions, in an empty room, with the presence of a single intruder and the presence of multiple intruders. Based on the RSSI values, we found that there are distinctive features of data that can be utilized as fl ags for classifying the three above conditions. Besides that, to justify the effi ciency of system performance, we also examined the sensitivity of RSSI values towards the variation of temperature. Our results show that the RSSI average values for both morning and night were practically the same. However, during the afternoon, the RSSI signal strength fl uctuated by − 1.0 dBm. These results motivate the development of an alarm system that only uses the RSSI statistics to detect human presence.
