Characterization of fabricated optical fiber for food irradiation dosimetry

Food irradiation is a process carried out in order to improve hygienic quality and germination control, retarding sprouting, also enhancing physical attributes of the food product. In order to provide for food safety, radiation dosimetry in irradiated foods is required. In present studies use is made of germanium doped (Ge-doped) optical fibres of various form and dimensions. The fibres are irradiated using a gamma source irradiator (Gamma Cell 220 Excel), with doses from 1 kGy up to 10 kGy. For the particular Ge-doped optical fibres, investigation has been made of linearity with dose, reproducibility, and fading, intercomparisons being made. The fibres all exhibit TL yields that are linear with dose from 1 kGy up to 10 kGy, exceeding the dose range of all commercial high dose dosimeters used in the food irradiation industry. In respect of the flat fibre dosimeters, the mean reproducibility was found to be within 0.53% to 4.96%, also offering low signal loss (fading), within 13.41% (for fibres of cross-sectional dimensions 60 x 180 μm) to 20.12% (for fibres of cross-sectional dimensions 200 x 750μm), after 22 days of storage

Meaning makers at work: how do above average and average students make sense of English and Bahasa literary texts?

This study seeks to explore the relationship between eight types of comprehension questions and eight types of coded discourse units which are based on the eight subskills of Lunzer and Gardner (1979). In general each reasoning strategy used by selected above average and average readers in response to each test item is interpreted and categorized as one of the eight sub-skills. Currently, no similar reading research has been done in this area. The findings of this table suggest that both the above average and average readers' reasoning strategies, in all the L1 and L2 texts, reflect the usage of all the various Discourse Types (DTs) with the exception of DT 6 (M) and DT 7 (S) which are under utilized by both groups of readers (see rows 6 and 7 in Table 25). The good readers' responses seem to be more specific and focus on every single question type itself. The higher context-specific FSI scores of the good readers, as seen diagonally, reflect the regulatory power of the readers in monitoring their comprehension. It also suggests that the comprehension discourse strategies of the readers are more active in their attempts to reason out their understanding of the questions. This may suggest that the good readers' mastery of the content of the texts make them rely less on the DT Forming Judgment (J). These findings seem to indicate that the above average readers evidence a greater reflection on every QT (except on QT(J)) than the average readers. Quantitatively, the above average readers are found to be different in their reflections of their reasoning strategies from the average readers. The reasoning processes of the above average readers are much more focused on each QT than those of the average readers. This shows that the good readers were able to activate their reasoning processes within the sphere of each of the QTs individually, relying less on other skills. This phenomenon strongly suggests that instruction in improving poor readers' comprehension monitoring strategies should teach this unique strategy of the good readers. In other words, reading teachers should improve the average and poor readers' awareness and knowledge in comprehension strategies because logically, an increase in awareness of strategic knowledge may improve pupils' performances on reading comprehension tasks. Whether such differences, as seen by the patterns of the Factor Specificity Index (FSIs), qualitatively reflect better and more effective reasoning strategies by the above average readers than by the average readers may need further investigation

Aplikasi Metode Multycriteria Decision Making (MCDM)dengan Teknik Pembobotan Dalam Mengidentifikasi Dan Mendesain Kawasan Konservasi Perairan Daerah Di Kabupaten Luwu Utara, Provinsi Sulawesi Selatan

The study, in 2012, has successfully formulated with the MCDM for each allocation of space in KKPD allotment (core areas, sustainable fisheries zone, used zone, and other zones). This weighting techniques need to be tested and be implemented in identifying and designing the KKPD in the study area. This study aims to identify and map the biophysical conditions and the potential of coastal and marine natural resources in marine conservation area candidate, North Luwu Regency; to identify the areas suitable for the KKPD based on weighting technique with the MCDM method; and to evaluate potential candidates for marine protected areas in the coastal region. This study used a survey method to perform in situ measurements of physico-chemical parameters, conducted a survey of coastal ecosystems using the transect method. The socio-economic data of coastal communities were collected using the questionnaire. The biophysical conditions and marine resources were analyzed using descriptive statistical methods. The results showed that the candidate region has a rich diversity of coastal ecosystems, but the ecosystem, particularly seagrass beds and coral reefs have been in damaged category. Only the mangrove ecosystem that was still in a good condition category with moderate-to-heavy levels of density. There were 6 species of seagrasses and 6 species of mangroves and 71 species of reef fish. It was discovered 2 regions corresponding to the allotment of the Core Zone, which is in the Region I and III with the total area of 654.22 hectares. For sustainable fisheries zone, Region II and IV would be the first choice with the total area of 620.27 hectares. The Used Zone was identified in the Region V with total area of 480.66 hectares. The total area of the region was equal to 1755.15 hectares. Marine protected areas of was suggested to the protection of coastal ecosystems including mangroves, seagrass beds, and coral reefs and its associated biota, especially the protection of local feeding ground of several species (sea turtles and dugongs)

THE STATUS OF ORGANIC POLLUTION AND THEIR SPATIAL DISTRIBUTION IN THE WEST COAST OF SOUTH SULAWESI

Aquaculture activities produce organic wastes that are discharged into coastal waters and may impact the water quality. This research aimed to study the status of organic pollution and its spatial distribution on the west coast of South Sulawesi, Indonesia. Water was sampeld from two locations (Punaga Village, Takalar Regency (an open water system), and Bojo Village, Barru District (in a bay, a semi-closed water system)). Water quality was assessed by using the STORET index. Whilst to assess the spatial distribution of organic waste, an interpolation technique was used. Results showed that the water quality was categorized as highly polluted by organic pollution. The distribution of the organic pollutant, however, showed a different spatial pattern between the two locations. The difference was may be due to the different origin of the pollutant and geomorphology of the sampling locations

Revealing Influenced Selected Feature for P2P Botnet Detection

P2P botnet has become a serious security threat for computer networking systems. Botnet attack causes a great financial loss and badly impact the information and communication technology (ICT) system. Current botnet detection mechanisms have limitations and flaws to deal with P2P botnets which famously known for their complexity and scalable attack. Studies show that botnets behavior can be detected based on several detection features. However, some of the feature parameters may not represent botnet behavior and may lead to higher false alarm detection rate. In this paper, we reveal selected feature that influences P2P botnets detection. The result obtained by selecting features shows detection attack rate of 99.74%
