DEVELOPMENT OF A SEMI-AUTOMATED TOBACCO STRIPPING MACHINE UTILIZING STRING TRIMMERS

Sperry, Robert George 01 January 2011 (has links)
Conventional stripping of burley tobacco is labor intensive and typically requires 50 to 75 worker hours per acre (wkr•hr/ac). The goal of the project was to reduce labor by optimizing leaf removal by string trimmer heads using combinations of strings lengths and motor speeds. In tests conducted on a single grade, all leaves outside the grade were removed by hand. Plants were run through the machine for sting lengths of 5, 7 and 9 inches and associated motor speeds which were monitored and recorded. Stripping efficiencies were calculated for each plant and collectively for each set of four plants. The machine was then tested for three grade stripping efficiency. Particle size analysis tests were run to determine potential losses due to leaf shredding. Efficiencies for single grade testing ranged from 93 to 96% for optimal string length and speed combinations. Stripping three grades by machine resulted in an average of 97% efficiency. Potential losses due to shredding accounted for 5.6% of the total weight mechanically removed. It is believed that this stripping concept, implemented on a full scale four grade basis, could result in savings of at least 18 wkr •hr/ac [45 wkr•hr/ha].

Adverse welfare effects of regulations on small tobacco exporters: the case of Zimbabwe.

Matemba, Edward January 2005 (has links)
Regulations to reduce the consumption of tobacco products have dual effects on economies. Economies that are net consumers of tobacco products experience welfare enhancing effects as a result of these regulations. However, these regulations can have adverse welfare effects among net producing economies. Many studies have explored these welfare effects on net consuming economies, whereas the impacts among net producing economies have been neglected. This research paper examined the adverse welfare effects of smoking regulations on small tobacco exporting economies with, a comparative advantage in tobacco production.

Effekter av den nya tobakslagen 2018:2088 : En studie över hur studenter upplever att den nya tobakslagen påverkar cigarrettrökning / Effects of the new tobacco law in Sweden : How students appreciate the new law to affect cigarette smoking

André, Lovisa January 2020 (has links)
A new Swedish tobacco law was decided in 2018 which originated from an EU-directive from 2014. The aim of the directive is to integrate the member states’ legislation on tobacco control and to minimize the risks of young people getting in touch with tobacco. And furthermore, the aim of the Swedish law is to minimize the negative health effects from tobacco use. This research shows that the new tobacco regulation in Sweden has led to a decrease in smoked cigarettes among students in Sweden as well as an experienced decrease in risk to be exposed to second-hand smoking. This means the new law has led to positive effects on cigarette smoking amongst students and that the aim of the law therefore is fulfilled to at least some point. The majority of the smokers have though continued to smoke as much as before, which means the legislation does not succeed to reach everyone. To reach more people, further efforts are needed. Thus, governance through legislation on EU and national level is not enough, and the problem therefore requires efforts on multilevel. To continue the decrease, Sweden should take action in educative efforts to reach broader levels in its governance.

The Odd Man Out in Sub-Saharan Africa: Understanding the Tobacco Use Prevalence in Madagascar

Mamudu, Hadii M., John, Rijo M., Veeranki, Sreenivas P., Ouma, Ahmed E.Ogwell 19 September 2013 (has links)
Background: The tobacco industry has globalized and tobacco use continues to increase in low- and middle-income countries. Yet, the data and research to inform policy initiatives for addressing this phenomenon is sparse. This study aims to estimate the prevalence of adult tobacco use in 17 Sub-Saharan Africa (SSA) countries, and to identify key factors associated with adult tobacco consumption choices (smoked, smokeless tobacco and dual use) in Madagascar. Methods. We used Demographic Health Survey for estimating tobacco use prevalence among adults in SSA. A multinomial logistic regression model was used to identify key determinants of adult tobacco consumption choices in Madagascar. Results: While differences in tobacco use exist in SSA, Madagascar has exceptionally higher prevalence rates (48.9% of males; 10.3% of females). The regression analyses showed complexity of tobacco use in Madagascar and identified age, education, wealth, employment, marriage, religion and place of residence as factors significantly associated with the choice of tobacco use among males, while age, wealth, and employment were significantly associated with that of females. The effects, however, differ across the three choices of tobacco use compared to non-use. Conclusions: Tobacco use in Madagascar was higher than the other 16 SSA countries. Although the government continues to enact policies to address the problem, there is a need for effective implementation and enforcement. There is also the need for health education to modify social norms and denormalize tobacco use.

Implementation and Evaluation of a School-Based Anti-Tobacco Program in Mauritius: A Pilot Study to Assess the Usefulness and Reliability of a Tobacco Use Prevention Education Instrument

Hussenbocus, Shariah 14 December 2018 (has links)
Tobacco use among Mauritian adolescents has increased steadily since 2008. Currently, Mauritius has not implemented any school-based anti-tobacco program and there is no instrument to assess the effectiveness of existing anti-tobacco school policies. Since the first cigarette can rapidly lead to nicotine dependence, targeted interventions must be assessed before established patterns of smoking appear. This study evaluated a tobacco use prevention education instrument to determine the effectiveness of a school-based anti-tobacco program. 26 male students completed a survey before and after receiving anti-tobacco lessons. Smoking initiation age could not predict likelihood of tobacco addiction (r(12)=0.320, p=0.311). However, after receiving the anti-tobacco lessons, participants were less likely to believe that youth who smoke have more friends (p < 0.001) and were more knowledgeable about tobacco’s dangers (t(25)=3.94, p=0.001). This indicated that, with a few changes, the instrument can be used to assess the implementation of a school-based anti-tobacco program in Mauritius.
