A Feasibility Study for an Irrigation System in Lubonja, Albania

Johansson, Susanne, Mogielnicki, Linda January 2008 (has links)
This project is a part of the collaboration between the Swedish-Albanian Association in Mariestad and the Albanian Centre of Excellence in Tirana. The project is a preliminary feasibility study for an improved irrigation system in the mountain village Lubonja, Korça Region, Albania. When the Albanian communism regime fell in 1990, the infrastructure degenerated and the irrigation systems where almost destroyed. Various organizations, like the World Bank, have assisted with the restoring of the systems, especially in the mountain areas. Today, the most of the systems is in functional condition. The village of Lubonja is located in South-Eastern part of Albania. The village is a part of the Korça Region and is located 27 km from the town Korça. The fields have an altitude that varies from 930 to 870 meters above sea level and have a total approximate size of 490 hectares. Lubonja has a population of almost 560 inhabitants and the prime livelihood is farming. Today, each family is self sufficient and cultivate many kinds of crops on their fields. There are two main streams in the region; the Lubonja River and a river from the Rehova mine area. Lubonja River comes from the mountains and flows through the village, where grey water and black water is added. The other stream is mixed with the polluted water from the old copper mine. There is also a reservoir on the hill side of the mountain which is for irrigation use only. To calculate the needed amount of water, a small field survey has been performed. The different parts in the survey are; soil type, water quality, evaporation and climate data. The results of the field survey were compiled, with assistance of Dr. Kovaçi, Institute of Land in Tirana. It resulted in the irrigation period and the needed amount of water during the irrigation season in Lubonja. The needed amount of water varies from 1250 m3/ha to 4300 m3/ha depending on the crop and the period when irrigation is necessary is from the middle of May to the end of September. The proposed design of the system is a combination of restoring the old canals in the area, where the system was sufficient and installing a pipe system in the area, where the old system was insufficient. The idea is to irrigate the area with the water which is now wasted from the reservoir due to leaking valves and shallow streams. To eliminate the waste of water, a pipe will lead the water from the outlet of the reservoir to a switch where there is a y-crossing. After the switch one pipe goes to the main canal and the other leads the water to area where the pipe system is implemented. The pipe system will prepare for a usage of modern technology like drip irrigation and sprinklers. Each farmer will be able to choose how to use the water by connecting hoses to taps. Due to the high position of the reservoir the pressure in the pipes will be sufficient without using a pump. The calculations for the system are divided into two parts. The first part is the canals, where an appropriate cross section and the needed amount of concrete are calculated. The amount of concrete for the canals is approximately 200 m3. The second part is the pipe system, where the pressure and velocity in the pipes and valves are calculated to be certain that a pump will not be needed and to get proper dimensions of the pipes. The maximum pressure is 1 471 500 Pa, the total outflow when all taps are open is 0.07m3/s and maximum velocity when tap 25 is open is 24.0 m/s. It is important that a system like this is being implemented in close collaboration with the villagers.

Leksaker baserade på teknik sedda ur ett genusperspektiv : En studie om 6-åringars preferenser och användande av könsstereotypa konstruktionsleksaker

Bernström, Annelie January 2007 (has links)
Genom kvalitativa intervjuer med barn i förskoleklass och genom enkätundersökningar hos pedagoger har jag fått svar på mina frågeställningar som handlar om pojkar, flickor och deras leksaksval då det gäller teknikbaserade leksaker. Syftet var att försöka se om det fanns skillnader i valet och användandet av dessa leksaker och i så fall försöka tydliggöra dem, och dessutom ta reda på varför barnen är olika i sina leksakspreferenser. Resultatet påvisar att för barnen i denna förskoleklass är konstruktionsleksaker ett frekvent val i verksamheten. Alla barn leker med dessa leksaker, dock skiljer sig preferenserna åt beroende på om man är flicka eller pojke, både i hemmet och i förskoleklassen. Hur barnens preferenser uppkommer finns det delade meningar om, dock är huvudteorin enligt de forskarna/författare jag tagit del av, socialt betingat. Pedagogiska slutsatser är att som pedagog måste man arbeta på ett målmedvetet sätt då det gäller leksaker och genus, man skall alltid ha med sig att leken har stor betydelse i barnens utveckling. Nyckelord: genus, leksaker, preferenser, teknik / Through interviews with children in preschool class and through inquiries by questionnaire with their teachers, I have received answers of my question at issue about boys, girls and their choices of technical toys. The purpose was to see if there were any differences in choosing and using these toys, and also to find out if and why the children have different preferences. The results indicate that for the children in this preschool class the choice of construction toys is common in the activities. All the children play with these toys, but still there are different preferences among girls and boys, both at home and in preschool class. There are differences in opinion among earlier researchers what causes boys and girls to differ in preferences of toys, but the main theory is still that gender differences depend on the family and the community. Pedagogical conclusions are that as a teacher of young children, you have to work with awareness when it comes to toys and gender. You must never forget the important role toys play in the development of the children. Keywords: gender, technical, toys, preferences

”Ameh, eh, eh, vi kör det istället, för den är mycket lättare tror jag” : Förskolebarns kommunikation och samspel vid datorn / “Ameh, eh, eh, let’s do this instead, it’s much easier I think” : Pre-school children’s communication and collaboration at the computer

Lind, Sara, Tillander, Elin January 2008 (has links)
Syftet med studien var att observera hur förskolebarn kommunicerar och samspelar vid datorn, både verbalt och icke-verbalt. Syftet var även att belysa pedagogers uppfattningar om barns kommunikation och samspel och hur de organiserar datoranvändandet i verksamheten. Studien är av kvalitativ karaktär där videoobservationer och intervjuer användes. Totalt observerades 7 barn i 4-5 års ålder och 4 pedagoger intervjuades. Resultatet visade att barnen kommunicerade på olika sätt, detta delades in i 6 skilda kategorier: kommunikation om planering, emotionell kommunikation, icke-datorrelaterad kommunikation, kommunikation med spelets auditiva funktioner, kommunikation med datorn som person och kommunikation om spelet. Som mest höll sig kommunikationen om spelet som barnen spelade. Kroppsspråket bestod till störst del av gester i form av pekningar och vi märkte att gesterna hjälpte till där språket fattades. På båda förskolorna användes datorn i den fria leken till att spela på. Pedagogernas roll i barns spelande var passiv, de hjälpte till om barnen bad om hjälp eller när problem uppstod. Pedagogerna som intervjuades uttryckte att samspelet var positivt och att varken ålder eller kön spelade någon roll men däremot barnens språk- och kunskapsutveckling. Olika faktorer som vi upplever spelar roll i barnens kommunikation och samspel är val av spel/program, kunskaps-/utvecklingsnivån hos barnet, miljön och den vuxnes delaktighet.

Minor field study on traffic safety in Ghana : Pedestrian and cyclist facilities and access in central Accra

Eriksson, Göran, Davidsson, Tobias, Lundgren, Pauline January 2009 (has links)
This study is an analysis of the traffic situation for pedestrians and bicyclist, unprotected road users, in Accra’s Central Business District. A Swedish method, Calm streets, is used to identify conflicts in the mixed traffic situation. The findings reveal a large amount of conflicts between unprotected road users and motor vehicles. These conflicts cause congestions which have negative implications on the environment, health and economy. In addition an assessment of the quality of and access to pedestrian and bicycle facilities were conducted. This assessment indicates that the quality and access to the facilities are in general low, especially for the disabled, elderly and children. A larger Traffic Network Analysis and a Cost Benefit Analysis are needed to address these problems for stakeholders and decision makers.

The Eastern Link : A sustainable discourse?

Niskanen, Johan, Gröndal Andersson, Joakim January 2009 (has links)
The local newspapers in Sweden are often used as an arena where groups of different political leanings try to frame current events to suit their purposes. Therefore how the news media presents the discussed issue and how it relates to sustainable development are important for a democratic process. One of the largest infrastructural projects in Sweden currently is the Eastern Link and there are many economical, social and ecological concerns when constructing such a large infrastructural project. It is therefore important to look at how sustainable development is represented in the local news media when concerning this infrastructural project. The aim of this thesis is to study how the local media presents the Eastern Link project in relation to sustainable development and how it affects democracy. This thesis critically discusses the different parts of sustainable development; the impact of and on economical issues, social issues and ecological issues in relation to the study material. Both a quantitative approach and a qualitative approach are used as a method. The thesis also links the results of this study to previous research on communication and theories on sustainable development. The results show that neither of the newspapers Folkbladet or NT is presenting the Eastern Link in a balanced way from a sustainability perspective. A majority of the articles are focusing on the social discourse; this differs from previous research where the focus is on the economical discourse.

En studie i hur gymnasieelever ochlärare upplever att en personligdator påverkar elevernas lärande : med särskild fokus vid upplevda fördelar och nackdelar

Fällström, Jon January 2010 (has links)
Syftet med denna uppsats är att ge exempel på hur personliga datorer kan upplevas av eleveroch lärare på gymnasienivå. Metoderna som används är intervju med elever och lärare samtanalys av styrdokument och tidigare forskning inom området. I dag vill man från regeringsoch skolverkets håll förstärka skolans roll som förmedlare av kunskap inom IT-området. Dettalas om digitalkompetens, en färdighet man menar är nödvändig för att idag och i framtidenkunna verka i samhället. Att utrusta elever och lärare med personliga datorer i så kallade entill-en projekt är något som den senaste tiden vunnit mark. I Umeå väljer man hösten 2008och framåt att ge samtliga elever som börjar studera vid någon av de kommunala skolornatillgång till sådana datorer inom vad man benämner som elevdataprojektet. I denna studieintervjuar jag elever och lärare från en av de skolorna i kommunen.Både elever och lärare är i huvudsak positivt inställda till att få tillgång till och arbeta medpersonliga datorer. Lärarna ser bland annat fördelar i kunna anpassa lärandet till enskildaelever, att datorn förenklar inlämningar och spridning av information, att man nu lättare fårtillgång till information/material och att elever i behov av särskilt stöd har stora fördelar.Bland nackdelarna nämns bland annat okoncentration under lektionen att elever med godadatorkunskaper får större fördelar än andra och att personliga datorer ställer krav på elevernaseget ansvar. Eleverna menar att datorn låter gör det lättare att fåt tag på information, att manarbetar effektivare, att det är roligt att arbeta med en personlig dator. Nackdelar man uppleverär bland annat okoncentration under lektionerna, att datorn är tung att bära omkring och attelever med god datorkunskap har större fördelar än andra.Slutsatser som dras är bland annat att lärarens användande och integrerande av datorerna iundervisningen hur stor inverkan på upplevda fördelar och nackdelar samt att den ökadeokoncentrationen bör problematiseras då det i slutändan är osäkert om vad som är ökadokoncentration och vad som synliggjord okoncentration.

Vettinginspektion en utredning om vettinginspektioner leder till ökad arbetsbelastning ombord

Karlsson, Therese January 2011 (has links)
Abstrakt Jag har tittat på hur arbetsbelastningen ser ut idag ombord på svenska tankfartyg. Arbetet har belyst inställningen till och respondenternas upplevda känslor vid tiden för vettinginspektionen, men också vad det skulle kunna leda till. Under praktiktiden genomfördes personliga intervjuer samt intervjuer via mejl, och har även använt mig av både kvalitativa och kvantitativa undersökningar. Utredningen har visat att respondenternas goda inställning till vettinginspektioner, mest oro före vettinginspektionen, förberedelserna väl genomförda, hur inspektörens agerande påverkar besättningen. Samt resultatet av utredningen har även visat att det existerar en viss övertid runt en vettinginspektion. / Abstract I have looked at how the workloads are today onboard Swedish tankers. This work has shown the attitude to and the respondents experienced emotions by the time of the vetting inspection but also what this could lead to. During my on board training interviews were made including interviews by mail and for the investigation has also the usage of qualitative and quantitative methods. The investigation has shown that the respondents good attitude to vetting inspections, mostly worrying before the vetting inspection, well preparations, how the vetting inspector actions effects the respondents. The result of the investigation has also shown that it exists some overtime by the time of the vetting inspection.

Gustavsson, Hanna, Olsson, Sandra January 2009 (has links)
<p>Vi har gjort en barnbok med syftet att de yngsta barnen, på ettlustfyllt och vardagsnära vis, ska få ett intresse- och en inblick i detkretslopp som konsumtion och avfall utgör. Vi tycker att justkonsumtionens påverkan på miljön och främst klimatförändringarär ett aktuellt ämne och att barnboken som form är ett bra sätt attundervisa barn med. Vår bok vänder sig till barn i sexårsåldern.Processen har inkluderat faktainsamling som vår bok grundar sig i,kontinuerlig kontakt med barngrupp samt förskollärare sommålsättning att bokens innehåll ska tilltala den tänkta målgruppen.Resultatet av vårt arbete utvärderades tillsammans med fyra styckenlärare som i lugn och ro fått använda- och granskat boken. Vid ettutvärderingsseminarium samtalade vi kring hur de upplevt boken.Responsen var mycket positiv. Sammanfattningsvis kan vi draslutsatsen att en barnbok i berättande form är ett mycket bra medeldå man vill förmedla kunskaper, om avfall och konsumtion i ettkretslopp, till barn.</p>
