Collection of waste batteries in Portugal and Brazil

Selected papers from the 3rd Edition of the International Conference on Wastes: Solutions, Treatments and OpportunitiesThe legal aspects governing the disposal of used batteries were established in the nineties of the last century in Brazil and Portugal. In Brazil the law establishes the implementation of a reverse logistics system of this waste, similar to the system of Portugal, in which there is an extended producer responsibility. Portugal, subjected to the targets set by the European Union, has increased collection rates, with emphasis on the role of management entities. In Brazil, progress and the development of strategies to increase the collection rate have been observed, nevertheless, challenges associated with the increase of the coverage of the collection of batteries and also the public information about the disposal are relevant, as well as combating irregularities. Moreover, given the growing concern over the shortage of raw materials, proper management, including the collection and recycling of these wastes, can be seen as an important opportunity for both countries

Parametric study on ethanol fermentation of sweet sorghum [Sorghum bicolor (L.) Moench \u27SPV 422\u27] syrup using Saccharomyces cerevisiae 2011

Ethanol fermentation of sweet sorghum (SPV 422) syrup was conducted using Saccharomyces cerevisiae 2011. Different parameters were tested such as the effect of pH (4.5 and 5.5), initial Brix(20 °Brix and 25 °Brix) and incubation temperature (30 °C and 40 °C). A 2^k factorial design with replicated was used. After performing statistical analysis, pH and temperature were found to have significant effect on ethanol while all parameters significantly affected the total sugars consumption. For the reducing sugar consumption, only the initial sugar concentration was found to have a significant effect. Phenol- Sulfuric Acid Analysis and DNS Analysis were carried out for the determination of the total sugar concentration and reducing sugar concentration, respectively. Highest total sugar consumption of 87.60 % was recorder at pH 4.5, 20 °Brix and 40 °C while highest reducing sugar consumption of 86.04% was recorded at pH 4.5, 20 °Brix and 30 °C. High- Performance Liquid Chromatography (HPLC) was used to analyze the ethanol concentration of the samples. Highest ethanol concentration of 7.69% v/v was observed at pH 4.5, 25 °Brix and 30 °C incubation temperature. A fermentation profile of the same run was constructed and a fermentation efficiency of 27.92% was achieved

Reduction of setup times

Detta examensarbete behandlar hur olika företag reducerar ställtider samt hur de förhåller sig tillvarandra och beskriven teori. Problemområden som detta arbete behandlar är huvudsakligen standardiserad arbetssätt, produktionsplanering samt rengöring och underhåll. Arbetet går främst ut på att analysera tillvägagångssätten, faktorer samt metoder som bidrar till hur företag reducerar ställtider. Med hjälp av semistrukturerade intervjuer med fyra olika företag gjordes en litteraturstudie som stöd till de olika problemområden som företagen brottas med. Genomförande av kodning som går hand i hand med semistrukturerade intervjuer som var till hjälp för att få en tydligare helhetsbild över företagens syn på hur ställtider reduceras men gjorde det även enklare att hitta samband och mönster i förhållande till de problem som bidrar till ställtider. En analys och jämförelse gjordes mellan de fyra olika företagen för att se hur de eliminerar de problem som uppstår i produktionen. Det kunde påvisas att det rådde både likheter och olikheter bland företagen. De främsta likheterna var hur företagen eliminerade problemområden som uppstod. De olikheter som fanns bland de olika företagen kunde knytas till ledningens kunskap om just ställtidsreduktion, det rådde olika kunskapsnivåer. En annat viktig faktor som bidrog till olikheter bland företagen var deras storlek i volym som i sin tur även påverkar produktionsförmågan.This thesis deals with how different companies reduce downtime and how they relate to each other and described theory. Problem areas that this work deals with are mainly standardized working methods, production planning and cleaning and maintenance. The work is mainly about analyzing approaches, factors and methods that contribute to how companies reduce downtime. With the help of semi-structured interviews with four different companies, a literature study was conducted to support the different problem areas that the companies struggle with. Implementation of coding that goes hand in hand with semi-structured interviews that was helpful in gaining a clearer overall picture of companies' views on how set-up times are reduced, but also made it easier to find connections and patterns in relation to the problems that contribute to set-up times. An analysis and comparison was made between the four different companies to see how they eliminate the problems that arise in production. It could be shown that there were both similarities and differences among the companies. The main similarities were how the companies eliminated problem areas that arose. The differences that existed among the different companies could be linked to the management's knowledge of downtime reduction, there were different levels of knowledge. Another important factor that contributed to differences among companies was their size in volume, which in turn also affects production capacity

GEOTECHNICAL PROPERTIES OF SANDY SOIL CONTAMINATED WITH INDUSTRIAL WASTEWATER

The present work is devoted for studying the geotechnical and chemical properties of intact and contaminated sandy soil samples. The soil samples were obtained from Al-Kufa city that is located in the south-west of Iraq. The contaminant is a by-product industrial wastewater disposed from the refinery that supplies fuel for the thermal electricity power plant. The intact sandy soil samples were contaminated in the laboratory with four percentages of 10, 20, 40 and 100% of the weight of distilled water used in the soaking process and the soaking process continued for thirty days. The results of tests showed a slight increase in both liquid limit and particle size and a significant increase in the optimum moisture content with increasing the percentages of the contaminant. However, with increasing the percentages of the contaminant, there was a slight decrease in the specific gravity and maximum dry unit weight. In addition, there was a considerable decrease in the angle of internal friction and the coefficient of permeability. The angle of internal friction of contaminated soil samples decreased by 18 to 26% with increasing the contaminant percentage from 10 to 100%. The cohesion of soil samples decreased by 7 to 33% with increasing the contaminant percentage, this conclusion is limited to the soil samples contaminated with 10, 20 and 40%, but the cohesion of soil sample contaminated with 100 % of industrial wastewater increased by 7%

KARAKTERISASI TINGKAT KEJELASAN PERCAKAPAN DAN SIFAT DIFUSI DI RUANG KELAS STUDI KASUS RUANG TVST DAN RUANG 9019 INSTITUT TEKNOLOGI BANDUNG

Classroom and auditorium are space facilities that are generally known as learning spaces. In the process of learning, speech communication is a major activity. The standard ANSI-ASA: S12.60-2002 is a standard for acoustic classroom. This standard describes the measurement procedures and criteria for achieving good acoustic quality in the learning spaces. A frequent problem encountered related to the activity of speech communication in classrooms is the conversation clarity. One of the solutions in order to achieve this condition is by having a diffuse room, a condition where the sound energy is scattered within the same quality throughout the space. Clarity conversation is affected by the noise level and reverberation time. A case study conducted in two rooms with the same geometry, but differ in the use of absorption panels. This study measures the quality of speech intelligibility using acoustic parameters, namely T30, C50, RASTI, and background noise with the room impulse response recording method using omnidirectional loudspeaker dodecahedron and received by two microphones for subsequent data were processed using the Realtime Analyzer software. The level of sound diffusion in the room can be seen from the value of coherence (similarity) between two impulse response signals using Matlab calculations. The results of this study are 9019 rooms have reverberation time in the range of 0.8 to 1.2 s, 31.52 dB background noise, C50 -4.99 to 3.46 dB, RASTI 0.55 to 0.62, coherence 0.234 to 0.391, while TVST rooms have reverberation time in the range of 0.5 to 0.8 s, 26.96 dB background noise, C50 -2.6 to 8.89 dB, RASTI 0.61 to 0.75, coherence 0.218 to 0.419. These results provide evidence that the acoustical treatments in room TVST is able to increase the speech intelligibility quality
