#Bieber + #Blast = #BieberBlast: Early Prediction of Popular Hashtag Compounds

Compounding of natural language units is a very common phenomena. In this paper, we show, for the first time, that Twitter hashtags which, could be considered as correlates of such linguistic units, undergo compounding. We identify reasons for this compounding and propose a prediction model that can identify with 77.07% accuracy if a pair of hashtags compounding in the near future (i.e., 2 months after compounding) shall become popular. At longer times T = 6, 10 months the accuracies are 77.52% and 79.13% respectively. This technique has strong implications to trending hashtag recommendation since newly formed hashtag compounds can be recommended early, even before the compounding has taken place. Further, humans can predict compounds with an overall accuracy of only 48.7% (treated as baseline). Notably, while humans can discriminate the relatively easier cases, the automatic framework is successful in classifying the relatively harder cases.Comment: 14 pages, 4 figures, 9 tables, published in CSCW (Computer-Supported Cooperative Work and Social Computing) 2016. in Proceedings of 19th ACM conference on Computer-Supported Cooperative Work and Social Computing (CSCW 2016

Desempenho de porcas e leitoes em maternidades com diferentes sistemas de acondionamento termico no inverno.

O objetivo desta pesquisa foi estudar os efeitos de sistemas de acondicionamento termico, em maternidades para suinos, sobre as caracteristicas fisiologicas e o desempenho dos animais, durante o inverno. Um experimento em delineamento inteiramente casualizado em parcelas subdivididas, com dois tratamentos e dois periodos nas sub-parcelas, foi realizado. Os tratamentos usados foram: sala convencional (SSV) e sala com amplas aberturas de janelas e sistema de regulacao das aberturas por deio de cortinas (SAC). Foram coletados os seguintes dados: temperatural retal (TR), e frequencia respiratoria (FR) das porcas, perda de peso das porcas (PPP) e ganho de peso dos leitoes (GPL), consumo de racao (CRP), consumo de agua (CA), intervalo de desmamecio (IDC). As porcas do tratamento SAC apresentaram os menores valores de TR e FR. Nao houve diferencas entre os tratamentos sobre CRP e IDC. Houve diferenca entre os tratamentos para GPP, constatando-se que no tratamento SAC as porcas apresentaram as menores perdas. Nao houve diferenca entre os tratamento no GPL. Houve efeito do sistema de acondicionamento sobre as caracteristicas fisiologicas e o ganho de peso das porcas. O tratamento SAC e o melhor para as porcas no inverno

Biofuel Generation from Potato Peel Waste: Current State and Prospects

Growing environmental concerns, increased population, and the need to meet the diversification of the source of global energy have led to increased demand for biofuels. However, the high cost of raw materials for biofuels production has continued to slow down the acceptability, universal accessibility, and affordability of biofuels. The cost of feedstock and catalysts constitutes a major component of the production cost of biofuels. Potato is one of the most commonly consumed food crops among various populations due to its rich nutritional, health, and industrial benefits. In the current study, the application of potato peel waste (PPW) for biofuel production was interrogated. The present state of the conversion of PPW to bioethanol and biogas, through various techniques, to meet the ever-growing demand for renewable fuels was reviewed. To satisfy the escalating demand for biohydrogen for various applications, the prospects for the synthesis of biohydrogen from PPW were proposed. Additionally, there is the potential to convert PPW to low-cost, ecologically friendly, and biodegradable bio-based catalysts to replace commercial catalysts. The information provided in this review will enrich scholarship and open a new vista in the utilization of PPW. More focused investigations are required to unravel more avenues for the utilization of PPW as a low-cost and readily available catalyst and feedstock for biofuel synthesis. The application of PPW for biofuel application will reduce the pump price of biofuels, ensure the appropriate disposal of waste, and contribute towards environmental cleanliness
