The purpose of this study was to investigate the effects of skate (Raja kenojei) flour on the functional and sensory characteristics of Mandupi. Mandupi samples were prepared with wheat flour along with the addition of different amounts of skate flour, followed by functional measurements and sensory evaluations. According to the amylograph data, the composite skate flour-wheat flour samples had increased gelatinization temperatures with increasing skate flour content; whereas initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. In terms of color values, L and b values decreased, but the a-value increased with increasing skate flour content. Furthermore, the addition of skate flour increased hardness, springiness, chewiness, and adhesiveness in the samples. Overall, based on sensory evaluations, the Mandupi containing 5% skate flour was preferred over the other samples.

This paper presents a study on product design optimization to reduce the environmental impact of machining. The objective is to analyze the effect of changing the product design parameters such as its dimensions, and basic features on the environmental impact of machining process in terms of its energy consumption, waste produced and the chemicals and other consumables used up during the process. To realize this objective, we used a CAD model of a product with different design scenarios, and analyze their energy consumption using an environmental impact calculator method developed. The waste produced, and the consumables used up, such as lubricants and coolants were analyzed using environmental emission factors. Optimization methods using Genetic Algorithm and Goal Programming are applied to the product design parameters in order to get the best possible product dimensions with the least environmental impact of the machining process.

Fatigue and wear in wheels is often due to the forces and loading. These certainly have fundamental effects on reducing the wheel life and increasing the costs related to repairing and maintenance. Modeling and stress analysis of a wheel sample existing in the Iranian fleet have been performed in its contact with U33 and UIC60 rails. The results have been reviewed and analyzed in elastic and elastic-plastic phase and under static (railcar weight) and quasi static loads. Moreover, effects of wheel diameter, axle load, wheel material, rail type are analyzed.

In this paper, the reduction effect of dry (solid) lubrication on wheel flange wear rates is studied. The solid / dry lubricator systems were attached to the most front and furthest back axles of a coach in order to examine the wear behavior of the equipped wheels. An attempt is also made to make a comparison between wear behaviors of these wheel flanges having dry lubrication devices with non-lubricated wheels in other railcars. Finally, a comparison is made between life-cycle of wheels under investigation and other similar wheel types.

Background: Carcinoma of the esophagus is associated with significant morbidity and mortality. The most common subtype is squamous cell carcinoma (SCC). In the past three decades, the incidence of SCC has been reported to be decreasing whereas esophageal adenocarcinoma (AC) is increasing. This study assessed the trend of esophageal cancer in Brunei Darussalam over a three decades period. Materials and Methods: The National Cancer registry was searched for esophageal cancers from 1986 to 2012. Data on age, gender, racial groups (Malays, Chinese, Indigenous and foreign nationals) and histology type were collected. The rate (ASR) and Age Specific Incidence rate (ASIR) were calculated. Results: The predominant tumor type was SCC which accounted for 89% of all esophageal cancer. The gender ratio was 2.25: 1 (male: female) and the mean age at diagnosis was $66.9{\pm}12.9$ years, significantly younger for esophageal AC ($57.2{\pm}16.0$) compared to SCC ($68.1{\pm}12.0$, p<0.05), and among the foreign nationals (p<0.05 for trend). The proportions of SCC among all esophageal cancers in the various racial groups were: Malays (87.8%), Chinese (100%), Indigenous (100%) and foreign nationals (20%). None of the Chinese and Indigenous groups were diagnosed with esophageal AC. The overall ASR for esophageal cancer was 2.1/100,000; 2.0/100,000 for SCC with a declining trend and 0.17/100,000 for esophageal AC, without any trend observed. Among the two major racial groups; the Chinese has higher ASR (3.42/100,000) compared to the Malays (ASR 0.95/100,000). Conclusions: SCC is the predominant tumor type of esophageal cancer in Brunei Darussalam and more common among the Chinese. There was a declining trend in the incidence of SCC but not for esophageal AC.
