A review of risk factors, incidence and solutions for hepatocellular carcinoma
Liver cancer is one of the cancers that associated with high mortality rate. Incident of liver cancer always correlate with unhealthy life style, food contaminant (such as aflatoxin) and most importantly hepatitis virus infection. High mortality rate of liver cancer can be contributed by late detection of the disease, resistant of the liver cancer cell toward chemotherapy and inhibition of body immune system. The...

Potential utilization of cassava pulp for ethanol production in Indonesia
Cassava is one of the major crops produced in Indonesia. Cassava grows in all provinces in Indonesia. In the last decade, even though cassava plantation area is decreased, cassava production and its productivity in Indonesia have been on the increase steadily. The tendency of using cassava for ethanol production would affect supply of cassava for food. Cassava pulp, a by- product of tapioca industry is one of the...

Inter-generic grafting in watermelon for managing Meloidogyne species: A review
Watermelon (Citrullus lanatus) cultivars suffer considerable yield losses from infection by the root-knot nematodes due to the unavailability of nematode-resistant genotypes. Screening for nematode resistance within the family Cucurbitaceae demonstrated that wild watermelon (Cucumis africanus) and wild cucumber (C. myriocarpus) were highly resistant to Meloidogyne incognita races 2 and 4 and M. javanica,...

Fuzzy controlled multi-hop adaptive clustering (FMAC) for mobile ad hoc networks
To mimic the operations in fixed infrastructures and to solve the routing scalability problem in large ‘mobile ad hoc networks’, forming clusters of nodes has been proven to be a promising approach. However, when existing weighted clustering algorithms calculate each node’s weight, they either consider only one metric or rely on some metrics collected from extra devices. This often leads to a higher...

Investigation of water absorbency and color fastness of modal woven towels
Water absorbency and color fastness to perspiration, seawater and washing of modal terry woven fabrics were studied in this research. Weft and warp yarns were produced from 100% cotton and pile yarns were produced from 50/0% modal/cotton blended yarn. Terry woven fabrics were produced in five different pile heights. Water absorbency and color fastness tests were carried out on fabrics. It was determined that sinking...

Virtual reality adoption capability in Malaysian automotive manufacturing industry
Virtual reality and three-dimensional modelling technologies are mainly used in industry in many aspects. The automotive industry is considered as the initial group that uses virtual reality technologies. However, without adopting advanced technology, the automotive industry cannot compete with its global competition. In this study, six automotive companies in Malaysia were selected as case study to verify the virtual...

The alterations of tyrosine and tryptophane residues along with the evolution of tumor: Determination by synchronous fluorescence spectra
Synchronous fluorescence spectra were applied to assess tyrosine (Tyr) and tryptophane (Trp) residues in the plasma of patients with hepatocellular carcinoma, tumor-bearing mice and in cultured cells (HepG2 and L-02). The results showed for the first time that the fluorescent intensities of Tyr and Trp residues increased significantly in the plasma proteins of patients suffering hepatocellular carcinoma. There is a...

An efficient quantum-dot cellular automata full-adder
The most important mathematical operation is addition. Other operations such as subtraction, multiplication and division are usually implemented by adders. An efficient adder can be of great assistance in designing arithmetic circuits. QCA is a promising technology which seems to be a good candidate for the next generation of digital systems. So, an efficient QCA full-adder will facilitate creating QCA computational and...
