Paddy rice samples (Oryza sativa) were germinated to prepare germinated brown rice flours. Their functional properties and amylase activity were measured. Germinated samples had higher water absorption, oil absorption, and bulk density than those from ungerminated flours. Germinated rice flour had a least gelation concentration higher than the control flour. In addition, germination significantly changed the pasting properties of rice flour and increased the amylase activity. This study indicated that germination affected the functional properties of brown rice flour. It would be likely to design new food products using germinated brown rice flour.

The beam analysis, based on the assumptions of the Bernoulli-Euler theory, in free vibration has been largely investigated. Many researches focused on the transverse vibrations study, under the application of different boundary constraints where different theories were applied. The considered stiffness and mass matrices are those obtained by assembling the elementary ones resulting from the FEM use The Jacobi method allowed the solution of the eigenvalue problem. These well known concepts were applied to the study of beams with constant geometrical and mechanical characteristics having one to two overhangs with variable lengths. Murphy studied, by an algebraic solving approach, a simply supported beam with two overhangs of arbitrary length, which allows an experimental determination of the E elastic modulus.

The advantage of our paper offers a possibility of extending this approach to many interesting problems formed by beams vibrating transversally with various ends restraints.

Rose apples (Syzygium agueum Alston) cv. Tabtim Chan are economically important fruit for Thailand. However, because the peel of the rose apple is thin, the fruit deteriorates quickly and water retention is low. This study investigated the effect of chitosan treatment on the quality of rose apples cv. Tabtim Chan stored at an ambient temperature of 30 °C. The results demonstrated that at day 5 of storage, the fruit coated with 2% chitosan had a weight loss of 12.82% and a disease incidence of 14% which were significantly less than those of the control (22.12%, 24% respectively). Fruit firmness of the rose apples treated with 2% chitosan was significantly higher than that of the control (5.92 kg/cm² and 4.12 kg/cm² respectively). In conclusion, treating the rose apples with 2% chitosan reduces weight loss, disease incidence and maintains the fruit firmness of rose apples cv. Tabtim Chan compared with those which were untreated.

The research area was localized in the Indonesian Archipelago, at the latitude of eight and nine degrees S on the one of the Lesser Sunda group island provinces, Bali (563,3 km²). Two massive calderas (Mount Batur 1717 m above sea level.; Mount Sangiyang 2093 m above sea level) are one of the most prominent landforms in the chain of volcanic mountain ranges of the Bali Island. Lake Batur (17,18 km²) and Batur Spring (which are part of the freshwater lake system of Mt. Batur caldera) and also Danau Bratan Lake (one of the unconnected lakes next to the Mt. Sangiyang caldera), were selected for studies on the pollutants concentration levels in this volcanic area located in tropical climate. The research was aimed at determining the concentration of pollutants of natural (volcanic) and anthropogenic origin occurring in both lakes. The following parameters were determined: anions, metals, pH and conductivity. Based on the obtained dataset of initial studies it can be stated that the localization of aquatic ecosystems has the significant impact on the chemical composition of surface water.

A study was undertaken to compare the grazing system and stall feeding system in goats in Gulbarga district, Karnataka state. Twenty Osmanabadi goats were divided into two groups; stall feeding group and grazing group each containing 10 goats. The overall weight gain was significantly higher in stall fed group (7.90 ±0.12 kg) compared to grazing group (5.30 ±0.55 kg). Blood parameters (average Hb (g/dl), PCV (%) and RBC (10⁶/cmm) count) were higher in stall feeding group (9.16±0.68, 25.09±0.43 and 10.75±0.37 respectively) compared to grazing group (8.64±0.52, 22.97±0.16 and 8.97±0.42 respectively). Upon DLC analysis, different leukocytes were in the normal range in the stall fed group compared to the grazing group. On the 1^st day deworming was done for all the goats. At the end of the study, no Strongyle eggs were observed in both the groups. However, coccidial oocysts were found in three goats in grazing group. After three months of experimental period for 10 goats the profit was calculated to be $ 464.4 ($ 96.84 more) in stall fed group as compared to $ 367.56 in grazing group. Therefore goats grow healthier, gain better body weight, and are more healthy and farmers gain more profit in stall feeding system of goat rearing compared to grazing system.

Catalyst deactivation and its environmental consequences are believed to be an important issue seriously needed to be dealt with. In this study, a mathematical model of a spherical bed along with the catalyst deactivation in a long-term operation period for the methanol synthesis was investigated. The inside space of the two spheres reactor configuration was filled with the catalyst. The materials in the outer surface of the inner hemisphere were understudied. The equations solved at two dynamic and static levels via the finite difference method. It was revealed that, the resulting pressure drop as well as operation costs might have been lowered while the production capacity enhanced in comparison with the conventional reactors and overall leading to better environment protections. Furthermore, the analysis of the catalyst deactivation behavior indicated that a series of parameters including the reactor temperature and size, as well as the entering carbon monoxide and feed rates played an important role in the catalyst deactivation.

In 2010 a project entitled “Integrated Support System for Management and Protection of Water Dam Reservoir (ZiZOZap)” was initiated, to aid solving water management problems on a river and dam reservoir formed on it. An innovative system of continuous monitoring was created, that encompassed selected physical and chemical parameters of river and lake waters in three chosen sites. This article presents a selection of results, that were obtained thanks to the continuous monitoring. In particular, monitoring of parameters with high diurnal variability benefits from this measurement design. Sites that are essential for water management are recommended to be monitored in this way.

The objective of this study is to determine the dominance impact of environmental factors such as illuminance, humidity and temperature on worker productivity by Taguchi Method. A study was conducted under simulated environment factor which examined were the illuminance, humidity and temperature of the surrounding workstation area in the closed simulation lab. A set of representative data including the illuminance, humidity and temperature level and production rate were collected during the study. The production rate data were collected through observations and survey questionnaires while the illuminance, humidity and temperature level measured by valid apparatus and equipment. The Taguchi method was utilized to find the sequence of dominant factors that contributed to the productivity of the operator at that specified production workstation. The study reveals that the dominant factor that contributed to the productivity was temperature followed by illuminance and relative humidity.

This research aimed to study the ammoniation-fermentation technology based on palm plantations waste in increasing productivity of Pampangan Buffalo. Research used a Latin Square Design (RBSL) 4 X 4. The treatment consists of A = Grass+Concentrates, B = Grass+Palm Fiber+Concentrates, C = Grass+Ammoniation Palm Fiber+Concentrates, D = Grass+Ammoniation-Fermentation Palm Fiber+Concentrate. The observed variables were consumption of dry matter, crude protein, TDN, digestibility of (dry matters, organic matter, crude protein, and crude fiber), and body weights. The research showed that treatment using ammoniation-fermentation technology (EM-4 and urea) not significantly effected (P>0.05) consumption of dry matter, crude protein, TDN, digestibility of (dry matters, organic matter, and crude fiber), and body weights, but significantly effected (P< 0.05) digestibility of crude protein. It was concluded that the addition of urea and EM-4 through the amoniation-fermentation process were relatively equal over the consumption, digestibility, and body weight gain of Pampangan Buffalo.

Road Surface Monitoring (RSM) is the process of detecting the distress on paved or unpaved road surfaces. The primary aim of this process is to detect any distress (such as road surface cracks) at early stages in order to apply maintenance on time. Early detection of road cracks can assist maintenance before the repair costs becomes too high. Local authorities should have an effective and easy to use monitoring process in place across the road network to meet their obligations.

The process of adding geographical identification metadata to the photos is called “Geo-tagging”. The proposed method in this work entails capturing GPS information when the photo is taken for the road surface distress, then attaching the photo to a map. The location disclosure in the act of geo-tagging of a photo provides qualities to the digital map. In that respect, a specific richness of the GIS dataset arises when they disclose the road surface distress photos.

This paper proposes a system for establishing a GIS database consisting of geo-tagged photos for local authorities to automate the process of recording and reporting road surface distresses. This system is easy to use, cost-effective, deployable, and can be used effectively by local authorities.
