Pre-storage Exogenous Application of Hydrogen Sulphide Reduces Sugar spot, Decay loss and Preserves Quality of Banana Fruit
This research focuses on effect of hydrogen sulphide treatment (control, 0.5, 1.0, 1.5 mM) during ambient storage on sugar spot, decay loss and postharvest quality of banana fruit. Hydrogen sulphide (H2S) treated fruit were stored at ambient conditions (25±2ºC and 60–65% of relative humidity) up to 9 days. In general, H2S treatment maintained higher values of lightness, peel firmness, reduce the respiration rate and ethylene evolution rate and extended shelf life of stored fruit by delaying progression of ripening. Moreover, H2S (1.0 mM) was found significantly better over other treatments in reducing sugar spot or peel browning spot and maintaining the desirable overall postharvest traits of the fruit. The findings indicated that H2S has a great potential for pre-storage application to preserve quality, reduce sugar spot and postharvest decay loss, possibly through the delayed onset of senescence, without any adverse effects on fruit quality

Endosseous dental implant fractures an analysis of 21 cases
Implant fracture is an infrequent cause of implant failure. The present study evaluates 21 fractured implants, with an analysis of patient age and sex, the type, length and diameter of the implant, positioning in the dental arch, the type of prosthetic rehabilitation involved, the number of abutments and pontics, the presence or absence of distal extensions or cantilevers, and loading time to fracture. Implant fracture was more common in males than in females (15:4), and the mean patient age was 56.9 years. Most cases (n = 19) corresponded to implant-supported fixed prostheses - 16 with cantilevers of different lengths ? while only two fractured implants were supporting overdentures instead of fixed prostheses. The great majority of fractured implants (80.9%) were located in the molar and premolar regions, and most fractured within 3-4 years after loading. It is important to know and apply the measures required to prevent implant fracture, and to seek the best individualized solution for each case - though complete implant removal is usually the treatment of choice
Political transition and emergent forest-conservation issues in Myanmar.
Political and economic transitions have had substantial impacts on forest conservation. Where transitions are underway or anticipated, historical precedent and methods for systematically assessing future trends should be used to anticipate likely threats to forest conservation and design appropriate and prescient policy measures to counteract them. Myanmar is transitioning from an authoritarian, centralized state with a highly regulated economy to a more decentralized and economically liberal democracy and is working to end a long-running civil war. With these transitions in mind, we used a horizon-scanning approach to assess the 40 emerging issues most affecting Myanmar's forests, including internal conflict, land-tenure insecurity, large-scale agricultural development, demise of state timber enterprises, shortfalls in government revenue and capacity, and opening of new deforestation frontiers with new roads, mines, and hydroelectric dams. Averting these threats will require, for example, overhauling governance models, building capacity, improving infrastructure- and energy-project planning, and reforming land-tenure and environmental-protection laws. Although challenges to conservation in Myanmar are daunting, the political transition offers an opportunity for conservationists and researchers to help shape a future that enhances Myanmar's social, economic, and environmental potential while learning and applying lessons from other countries. Our approach and results are relevant to other countries undergoing similar transitions

Finding all hops shortest paths with quality-of-service constraints
All hops optimal path (AHOP) problem is a problem that identifies the minimum weighted paths between a given source and a destination node for all hop counts. Nowadays, Data networks are increasingly used by streaming applications that require both bandwidth and delay guarantees. As a result, (AHOP) problem has become an
important issue to ensure that traffic with specific service guarantees is routed over the paths that can offer the minimum cost and also provide the bandwidth guarantee.
In this project, the shortest path is computed according to a user preference: either shortest widest path or widest shortest path for any number of hops. First option is for those who would like to choose the cost efficiency as the first priority and if there are two or more paths with the same cost; the program will select the one that can provide highest bandwidth. Second option is to guarantee the highest bandwidth between the source and destination with lower cost.
The optimal paths that meet these service guarantees are computed with C# programming using modified Bellman-Ford (BF) algorithm in this project. For efficiency purposes, every connected path is pre-computed for all possible service requests in the network. With this information, the optimal path with the lowest cost and maximum bandwidth is chosen according to the user preferences.Bachelor of Engineerin

Musical Genre Classification using Gaussian Mixture Models
Digital music is one of the most importantdata types, distributed by the Internet. Automaticmusical genre classification is very useful formusic indexing and retrieval. A method torecognize the genre of music audio is considered.In this paper, the input music is represented withDWT (Discrete Wavelet Transform) coefficientsand classifying the extracted features is performedusing Gaussian Mixture Models (GMM). UsingGMM the optimal class boundaries between fourgroups of genre namely, pop, classic, rock and jazzare obtained. The feature vector from featureextraction step uses wavelet coefficients byhierarchical decomposition as it is easy toimplement as well as it can reduce the computationtime and resources required. Given that GMM is arobust approach that could obtain very goodperformance and a solution based on it ispowerful, the classification is mainly composed ofGMM classifiers. The experimental results indicatethat the proposed approach offer encouragingresults
