Kartoitus Kaakkois-Suomen jätelietteistä, lietteen tuottajista ja käsittelymenetelmistä

In this thesis the sludge of Southeastern-Finland, the companies which produce sludge and the current methods and those still in development have been surveyed. 85 % of the waste sludge from industry comes from forest industries. The sludge from municipal waste water treatment plants is mostly used as a raw material for bioplants. The sludge from forest industry is mostly incinerated. New circulation methods increase the recycling value of the waste by creating new products but they still lack a full-scale plant. The political pressure from Europe and the politics driven by the government of Finland will drive circular economy forward and thus uplifting the processing options of waste slurries. This work is divided in two parts, first contains the survey and the second contains the experimental part and the operational methods based on the survey. In the experimental part wet hard sheet waste sludge was de-watered with shaking filter and the applications for waste sludge from cellulose factory were considered. The results are, that the wet hard sheet waste sludge can be dewatered to high enough total solids content for the inteded use. Also, the cellulose waste sludge has too high Cd content in almost all of the batches to be used as a land improment.

Kahden lämmitysjärjestelmiä valmistavan tuotantoyksikön toimintojen yhdistäminen kustannustehokkuuden lisäämiseksi

Tämä työ käsittelee Oilon Oy:n tehtaan layout -suunnittelua, kun yhdistetään kaksi eri kiinteistössä toimivaa tuotantoyksikköä saman katon alle. Yksiköt ovat Hollolassa toimiva Oilon Home Oy ja Lahden pääkonttorissa toimiva Oilon Industry Oy. Yhdistämisellä haetaan säästöjä tuotantoyksiköiden välisistä logistiikkakuluista sekä kiinteistön vuokra- ja ylläpitokuluista ja samalla tehostetaan tehtaan sisäistä materiaalinkäsittelyä. Oilon Oy on toiminut Lahden pääkonttorissa jo yli 50 vuoden ajan ja sen tuotanto on kokenut historiansa aikana useita pienempiä muutoksia, jotka ovat jättäneet nykyiseen layoutiin paljon toivomisenvaraa. Jotta molemmat tuotantoyksiköt saadaan mahtumaan Lahden yksikköön, on sinne saatava luotua tarvittavat tilat siellä olemassa oleville toiminnoille ja Hollolan yksiköstä saapuville tuotantolinjoille. Työn alussa perehdytään kirjallisuuden avulla siihen kuinka tuotanto on kehittynyt maailmalla lähihistorian aikana, jotta voidaan paremmin ymmärtää Oilon Oy:n nykytilanteeseen johtaneita syitä. Koska Hollolasta saapuville tuotantolinjoille ei ole tarkoitus rakentaa uutta tuotantotilaa, pyritään tilaa vapauttamaan Lahden tehtaalta varastointia tehostamalla ja sen logistiikkaa helpottamalla. Tämän vuoksi vertaillaan yleisimpiä tavaroiden varastointi ratkaisuita sekä tutkitaan kuinka materiaalin käsittelyä voitaisiin tehostaa varastossa ja tuotantosuluissa. Varastoinnin tehostaminen ei kuitenkaan yksin riitä vapauttamaan tarvittavia tiloja, joten layout-muutoksen aikana rakennetaan myös kaksi uuttaa varastohallia. Uudessa layout-suunnitelmassa huomioidaan kunkin solun nykyiset ja tulevat tilantarpeet, sekä rakennetaan ne niin, että työvoimaa voidaan käyttää niissä joustavasti eri tuotteiden valmistamiseen. Tutkimusmetodeina käytetään teemahaastatteluita, joilla selvitetään työntekijöiden tarpeet sekä kirjallisuuden avulla perehdytään Lean-tuotantoon, kanban:iin, 5S:ään ja arvovirta-analyysiin. Näitä soveltamalla saadaan luotua tehokkaasti toimiva kokonaisuus, jolla tavoitellut säästöt saadaan toteutumaan.

Ympäristö- ja turvallisuustoiminnan kehittäminen kemikaaleja käyttävissä konepajoissa

Tämä diplomityö tehtiin Sampo-Rosenlewin Porin tehtaan toimeksiannosta. Työn tavoitteena oli kehittää ympäristö- ja turvallisuustoimintaa tehtaalla. Ympäristö- ja turvallisuustoimintaa kehitettiin luomalla toimintajärjestelmä sekä valitsemalla riskienhallintamenetelmä POA. Uusien työkalujen tuonti mukaan toimintakulttuuriin todettiin haastavaksi, sillä turvallisuus- ja ympäristökulttuuri on vielä matalalla tasolla. Ympäristö- ja turvallisuustoiminnan tasoa ja hallintakeinoja tutkittiin benchmarkkaamalla kolmea saman kokoluokan teollisuusyritystä ja keräämällä hyväksi todettuja metodeja toimintajärjestelmään. Sampo-Rosenlew on Porissa sijaitseva konepaja, joka valmistaa leikkuupuimureita ja metsäkoneita. Sampo-Rosenlew käyttää konepajana paljon kemikaaleja johtuen kolmesta maalaamostaan. Työn tavoitteena oli parantaa Sampo-Rosenlewin ympäristö- ja turvallisuusasioiden nykyistä tilaa erilaisten työkalujen avulla, joita yritykselle luotiin. Työssä kehitettiin Sampo-Rosenlewille toimintajärjestelmä ISO 14001 ympäristöjärjestelmästandardia ja OHSAS 18001 TTT- järjestelmästandardia mukaillen. Luotu toimintajärjestelmä on tulevaisuudessa tavoitteena sertifioida. Valittua riskianalyysimenetelmä POA:aa tullaan pilottivaiheessa testaamaan aluksi yrityksen maalaamoissa. Toimintajärjestelmä ja riskienhallintamenetelmä pyrittiin luomaan mahdollisimman yksinkertaiseksi, selkeäksi ja helpoksi kehittää. Näiden menetelmien käyttöönoton onnistumiseen vaikuttavat nykyinen toimintakulttuuri ja ylimmän johdon sitoutuminen asiaan. Järjestelmän käyttöönoton myötä on tavoitteena Sampo-Rosenlewin dokumentoinnin tason parantaminen ja kilpailukyvyn tehostaminen.

Metal music as critical dystopia : humans, technology and the future in 1990s science fiction metal

Metal Music as Critical Dystopia: Humans, Technology and the Future in 1990s Science Fiction Metal seeks to demonstrate that the dystopian elements in metal music are not merely or necessarily a sonic celebration of disaster. Rather, metal music's fascination with dystopian imagery is often critical in intent, borrowing themes and imagery from other literary and cinematic traditions in an effort to express a form of social commentary. The artists and musical works examined in this thesis maintain strong ties with the science fiction genre, in particular, and tum to science fiction conventions in order to examine the long-term implications of humanity's complex relationship with advanced technology. Situating metal's engagements with science fiction in relation to a broader practice of blending science fiction and popular music and to the technophobic tradition in writing and film, this thesis analyzes the works of two science fiction metal bands, VOlvod and Fear Factory, and provides close readings of four futuristic albums from the mid to late 1990s that address humanity's relationship with advanced technology in musical and visual imagery as well as lyrics. These recorded texts, described here as cyber metal for their preoccupation with technology in subject matter and in sound, represent prime examples of the critical dystopia in metal music. While these albums identify contemporary problems as the root bf devastation yet to come, their musical narratives leave room for the possibility of hope , allowing for the chance that dystopia is not our inevitable future.

Canadian Shredded Wheat Company Fonds

In 1893 Attorney Henry Drushel Perky and William H. Ford invented a machine for the preparation of cereals for food. Perky soon realized that the actual cereal biscuits were more popular than the machines and he opened Shredded Wheat plants in Massachusetts and Niagara Falls, New York. In 1904, the Niagara Falls, Canada plant was opened. These factories also served as tourist attractions. In 1907, one hundred thousand people visited the plants on both sides of the border. In 1928, the company was sold to The National Biscuit Company and the product name changed to Nabisco Shredded Wheat. The name of the plant was changed to Nabisco Foods in 1956 to reflect the variety of foods that were being produced at that time. In 1985, Nabisco was purchased by J.R. Reynolds thus forming RJR Nabisco. In 1994, RJR sold its breakfast cereal business to Kraft Foods and the international licenses to General Mills. Shredded Wheat is now integrated into the Post Foods portfolio. with information from: Niagara Falls Canada a History by The Kiwanis Club of Stamford, Ontario Inc. and Business Source Complete

Niagara Falls Handbill Collection, 1838-1886, n.d. (non-inclusive)

According to legend, the Burning Springs were discovered by early natives in the Niagara Peninsula. Bridgewater Mills was built on the site of the spring. During the excavation of the factory; workmen uncovered the spring. Samuel Street and Thomas Clark recognized the potential of this as a tourist attraction so they built a wooden shelter over the spring. The spring was covered with a barrel with a pipe protruding from it. This became the first tourist attraction at Niagara. The Cave of the Winds was a cavern located behind the Bridal Veil Fall. It was originally named the Aeolus Cave. In 1920, a sudden rock fall from the ceiling killed 3 tourists. The cave was destroyed in 1955 as it was deemed dangerous. The captain of the Maid of the Mist was usually a farmer who owned the land where the ship docked. In 1846, the first steam powered Maid of the Mist was launched. By 1848, the first suspension bridge was built over the gorge and the main purpose of the Maid of the Mist was no longer to carry people who needed to travel, but now the focus was on people who wanted to view the Falls at close range.

Planification de la récolte et allocation des produits aux usines

L’industrie forestière est un secteur qui, même s’il est en déclin, se trouve au cœur du débat sur la mondialisation et le développement durable. Pour de nombreux pays tels que le Canada, la Suède et le Chili, les objectifs sont de maintenir un secteur florissant sans nuire à l’environnement et en réalisant le caractère fini des ressources. Il devient important d’être compétitif et d’exploiter de manière efficace les territoires forestiers, de la récolte jusqu’à la fabrication des produits aux usines, en passant par le transport, dont les coûts augmentent rapidement. L’objectif de ce mémoire est de développer un modèle de planification tactique/opérationnelle qui permet d’ordonnancer les activités pour une année de récolte de façon à satisfaire les demandes des usines, sans perdre de vue le transport des quantités récoltées et la gestion des inventaires en usine. L’année se divise en 26 périodes de deux semaines. Nous cherchons à obtenir les horaires et l’affectation des équipes de récolte aux blocs de coupe pour une année. Le modèle mathématique développé est un problème linéaire mixte en nombres entiers dont la structure est basée sur chaque étape de la chaine d’approvisionnement forestière. Nous choisissons de le résoudre par une méthode exacte, le branch-and-bound. Nous avons pu évaluer combien la résolution directe de notre problème de planification était difficile pour les instances avec un grand nombre de périodes. Cependant l’approche des horizons roulants s’est avérée fructueuse. Grâce à elle en une journée, il est possible de planifier les activités de récolte des blocs pour l’année entière (26 périodes).

L’influence de la coopération patronale-syndicale sur le fonctionnement et le degré d’autonomie des équipes de travail

Cette étude traite du travail en équipe et de la coopération patronale-syndicale. Nous avons évalué l’influence de la coopération patronale-syndicale sur le fonctionnement et l’autonomie collective des équipes de travail. La méthodologie utilisée s’appuie sur une étude de cas contrastés du point de vue de la variable indépendante (l’intensité de la coopération patronale-syndicale), en neutralisant le plus grand nombre possible de variables de contrôle pouvant influencer la variable dépendante (fonctionnement et autonomie des équipes de travail). Des entrevues semi-structurées avec les représentants des deux usines sélectionnées ont confirmé que la coopération patronale-syndicale était élevée dans une usine et faible dans l’autre. L’analyse des données relatives à notre variable dépendante est basée principalement sur les résultats d’un questionnaire et les données obtenues indiquent que les répondants de l’usine d’Alma font des évaluations plus élevées des aspects liés aux dimensions de la variable dépendantes et celles-ci recouvrent des aspects axés sur la gestion des opérations alors que celles où les évaluations sont plus élevées à Kénogami concernent majoritairement des aspects plus secondaires. Notre hypothèse est essentiellement confirmée et démontre une relation positive entre un degré élevé de coopération patronale-syndicale et l’évaluation par les membres du fonctionnement et de l’autonomie collective de leur équipe. Cette relation positive est cependant mitigée, car elle ne se vérifie pas pour certaines dimensions qui renvoient à des aspects plus secondaires de l’autonomie collective des équipes de travail.
