Collective PV nano-grid for households in Linga Linga : A Minor Field Study in Mozambique

Diaz Hjelm, Wilma, Olsson, Ellie January 2022 (has links)
About a third of Mozambique’s population has access to electricity, and the same number in rural areas, where most of the population lives, is down to 5 %. Small-sized off-grid solutions are economical alternatives to increase the electricity access rate in rural areas, and solar power is a common energy source due to price and weather conditions. Still, the economical aspect is the main hindrance to an increased electrification rate in Africa. This report aims to investigate how to make electricity affordable, in a sustainable way, by answering the main research question “What is the capability, economically, socially, and technically, for a shared nano off-grid system in the village Linga Linga?”. This was done by performing a Minor Field Study in the village Linga Linga, in southern Mozambique, with the help of the non-profit organization Project Vita. A collective nano-grid photovoltaic (PV) system was installed to electrify three households, including nine houses and eleven people, where the wage earners are all women. Before the construction and installment of the PV system, the first round of two interviews was conducted to investigate the energy situation for the households. After the interviews, the main components of the energy system: PV panels, inverter, charge controller, batteries, and cables, were sized and purchased. The energy system was sized to cover an energy demand of eleven Light-Emitting Diode (LED)-lights, four 3 W and seven 5 W, lit all day and all night, and three outlets for charging cell phones eight hours a day. This corresponds to an energy demand of 1,369 Wh per day, and a maximum power demand of 77 W. The resulting system cost is 87,570 Mozambique Metical (MZN), or 1,400 United States Dollars (USD). When calculating the technical lifetime to be 20 years, three of the main components must be replaced. That results in a system cost of 122,470 MZN, 1,960 USD, and the cost per wage earner of the participating households is 4.3 % of the average Mozambican’s annual salary. After the system had been running for about a week, the second round of interviews was carried out. On the same occasion, the households were informed about the maintenance and usage of the system, and they were handed manuals and contracts to sign. The interviewees reported that they had been working for more hours a day, handicrafts being their main source of income, thanks to the electric lights. The women were positive about collective ownership and sharing electricity and stated that they prefer a collective system to separate ones, even for the same cost. The interviews showed that the energy demand was lower than what the system was sized for, meaning that a system designed for the actual energy demand would have been both cheaper and smaller. However, the energy behavior could change with time as society develops and the users get more familiar with electricity. No clear answers were obtained regarding the willingness to pay (WTP) for the system, and the interpretation is that the household, in their current situation, cannot consider buying an energy system comparable to the prototype built for this report, due to the system cost. A collective solar nano-grid in rural Mozambique is concluded to be a well-functioning solution and one of the more economical electrification alternatives. Although the prototype in this study was too expensive for the participating households to pay for by themselves, it could support sustainable development and open for possibilities like increased productivity and income. Moreover, it could be expanded by connecting more loads and upscaling to further cut the system cost per person and increase the societal benefits. / Ungefär en tredjedel av Moçambiques befolkning har tillgång till elektricitet, och motsvarande andel på landsbygden, där majoriteten av befolkningen bor, är 5 %. Mindre off-grid lösningar är ekonomiska alternativ för att elektrifiera landsbygden, där solkraft är en vanlig energikälla på grund av det relativt låga priset och väderförhållandena med goda förutsättningar. Den ekonomiska aspekten är dock fortfarande det främsta hindret för att öka Afrikas elektrifieringsgrad. Den här rapporten syftar till att undersöka hur elektricitet kan göras tillgänglig för alla, på ett hållbart sätt, genom att besvara frågeställningen ”Vad är möjligheterna, ekonomiskt, socialt, och tekniskt, för ett delat nano off-grid system i byn Linga Linga?”. Detta utreds genom att genomföra en Minor Fields Study i byn Linga Linga i södra Moçambique med hjälp av välgörenhetsorganisationen Project Vita. Ett nano-nätsystem drivet av solceller installerades, innefattande tre hushåll med nio hus och elva personer, med endast kvinnliga inkomsttagare. Innan byggnationen av solcellssystemet genomfördes intervjuer för att undersöka hushållens energisituation. De mest fundamentala systemkomponenterna; solcellspaneler, växelriktare, solcellsregulator, batterier och kablar, dimensionerades och införskaffades efter intervjuerna. Energisystemet utformades efter ett energibehov på elva Light-Emitting Diode (LED)-lampor, varav fyra 3 W och sju 5 W, tända dygnet runt, och tre uttag för att ladda mobiltelefoner åtta timmar om dagen. Detta motsvarar ett energibehov på 1,369 Wh per dag, och ett maximalt effektbehov på 77 W per dag. Den resulterande systemkostnaden är 87 570 Mozambique Metical (MZN), eller 1 400 United States Dollar (USD). För att räkna om systemkostnaden för en teknisk livslängd på 20 år måste tre av systemets huvudkomponenter bytas ut, vilket resulterar i en systemkostnad på 122 470 MZN, 1 960 USD. Kostnaden per inkomsttagare i de deltagande hushållen utgör då 4,3 % av den årliga moçambikiska medelinkomsten. När solcellssystemet varit i gång i en vecka utfördes en andra omgång intervjuer. I samband med detta informerades hushållen om skötsel och användning av systemet, och mottog manualer och kontrakt. Det framkom att kvinnorna, tack vare den elektriska belysningen, hade kunnat arbeta längre på kvällarna med sina hantverk - deras främsta inkomstkälla. De var positiva till det kollektiva ägandet av systemet och sade sig föredra ett delat system framför varsitt separat, även för samma kostnad per person. Intervjuerna visade att hushållens energikonsumtion var mindre än systemet var designat för. Ett system anpassat efter det verkliga energibehovet hade därmed blivit både mindre och billigare. Energianvändandet kan dock förändras i takt med samhällsutveckling och användarnas bekantskap med elektricitet. Inga tydliga svar angående betalningsvilja (WTP) för systemet mottogs, och tolkningen är att hushållen, i deras nuvarande situation, inte kan tänka sig köpa ett energisystem som är jämförbart med studiens prototyp, på grund av den höga systemkostnaden. Ett soldrivet kollektivt nano-nät på Moçambiques landsbygd bedöms vara en välfungerande elektrifieringslösning och ett av de mest ekonomiska elektrifieringsalternativen. Fastän studiens prototyp var för dyr för att de deltagande hushållen kan det ses stödja en hållbar utveckling genom att öppna upp för möjligheter såsom ökad produktivitet och inkomst. Systemet skulle även kunna expanderas genom att koppla in fler eller större last, och byggas i större skala för att dra ner systemkostnaden per person och öka samhällsnyttan.

Design of a Sustainable Energy System for a Community Center in rural Mozambique : A Minor Field Study in Mozambique

Säll Magnusson, Emilia, Hahn, Melchior January 2023 (has links)
Access to energy is an important part in the development of most countries and societies, linked to both social and economic growth. Nevertheless, 70% of the population in sub-Saharan Africa does not have access to electricity, which brings consequences to several of these areas. A country to which this largely applies is Mozambique, where the percentage of the country's population that had access to electricity in 2021 was only 31.5%. Working towards the goal of electrifying the least developed countries in a sustainable way, solar technology is believed to have potential to play a vital role, as 60% of the best terrestrial-based global solar resources of the world are located in sub-Saharan Africa. Mini-grids and solar off-grid solutions can further help address the issue of lack of electricity access, especially in rural areas. In previous studies carried out in the village Linga Linga in Mozambique, off-grid solar solutions have been implemented for a small energy demand. With the intention of giving a larger part of the village’s population access to energy services such as light, phone charging and computer access, this thesis will investigate and design an off-grid PV system for a community center in the village. The main research question that will be answered in this report is "How can solar energy be used to supply a community center in the village Linga Linga with a low-cost, reliable and sustainable electricity supply?". To answer the research question, relevant data and information were collected through a literature study on the situation in Mozambique, off-grid PV systems and on PV system components such as inverters, batteries, PV panels and charge controllers. Interviews were also carried out in the village to be able to calculate the expected energy demand of the community center. The community center’s daily energy demand for weekends was estimated to be the highest, at 7 544 Wh with a maximum power demand of 1 230 W. To meet this requirement, the main components were dimensioned so that the system had a maximum power of 2 000 W, a battery storage capacity of 750 Ah and a system voltage of 24 V. For this system, the approximate total cost of the main components was calculated to 56 120 SEK. / Tillgång till energi är en viktig del i utvecklingen av de flesta länder och samhällen, kopplat till både social och ekonomisk tillväxt. Ändå har 70% av befolkningen i Subsahariska Afrika inte tillgång till el, vilket får konsekvenser för flera av dessa områden. Ett land som detta till stor del gäller är Mozambique, där andelen av landets befolkning som hade tillgång till el 2021 endast var 31.5%. I arbetet mot målet att elektrifiera de minst utvecklade länderna på ett hållbart sätt tros solteknik ha potential att spela en avgörande roll, eftersom 60% av världens bästa jordbaserade globala solresurser finns i Subsahariska Afrika. Mininät och solenergilösningar utanför nätet kan ytterligare hjälpa till att lösa problemet med bristande tillgång till elektricitet, särskilt på landsbygden. I tidigare studier utförda i byn Linga Linga i Mozambique har off-grid solenergilösningar implementerats för att tillgodose energibehov för små system. Med avsikten att ge en större del av byns befolkning tillgång till energitjänster som ljus, telefonladdning och datoråtkomst, kommer detta examensarbete att undersöka och designa ett off-grid solcellssystem för ett kultur- och fritidscentrum i byn. Den huvudsakliga forskningsfrågan som kommer att besvaras i denna rapport är "Hur kan solenergi användas för att förse ett kultur- och fritidscentrum i byn Linga Linga med en låg kostnad, pålitlig och hållbar elförsörjning?". För att svara på forskningsfrågan samlades relevant data och information in genom en litteraturstudie om situationen i Mozambique, off-grid solcellssystem och om systemkomponenter såsom växelriktare, batterier, solpaneler och laddningsregulatorer. Intervjuer genomfördes även i byn för att kunna beräkna det förväntade energibehovet för kultur- och fritidscentrumet. Kultur- och fritidscentrumets dagliga energibehov för helger uppskattades vara högst, 7 544 Wh med ett maximalt effektbehov på 1 230 W. För att möta detta krav valdes huvudkomponenterna så att systemet hade en maximal effekt på 2 000 W, en batterilagringskapacitet på 750 Ah och en systemspänning på 24 V. För detta system beräknades den ungefärliga totalkostnaden för huvudkomponenterna till 56 120 SEK.

Registered nurses’ experiences of caring for women in Jamaica who have been exposed to intimate partner violence : A qualitative study / Sjuksköterskors upplevelser av att vårda kvinnor i Jamaica som erfarit våld i nära relation : En kvalitativ studie

Achourpour, Nina January 2023 (has links)
Violence against women is an issue affecting women worldwide. Due to the high rates of women exposed to intimate partner violence, it is nearly impossible not to meet them in everyday nursing practice. Intimate partner violence is complex since it concerns physical violence as well as emotional, sexual, financial, and material aspects of abuse. Some women go to seek medical attention and herein lies the responsibility of the nurse to respond. Whilst many countries have handbooks or guidelines on how to support women exposed to intimate partner violence, nurses may encounter challenges in supporting these women in practice. This is particularly challenging in Jamaica, where there are reportedly high rates of intimate partner violence, but where various factors including limited resources and social and cultural norms, may limit the opportunities for nurses to support women exposed to intimate partner violence. Due to limited earlier research on the topic in Jamaica, there is a need for increased knowledge and understanding about how nurses in Kingston, Jamaica experienced the care they provide and how it affects them. / Våld mot kvinnor är ett problem som påverkar kvinnor globalt. På grund av den höga andelen kvinnor som utsätts för våld i nära relation är det nästan omöjligt att inte möta dem i den vardagliga vårdverksamheten. Våld i nära relation är komplext eftersom det berör fysiskt våld samt känslomässiga, sexuella, ekonomiska och materiella aspekter av övergrepp. En del av dessa våldsutsatta kvinnor uppsöker vård, och här ligger sjuksköterskans ansvar att reagera. Trots rutiner kring våld i nära relation, kan sjuksköterskor stöta på utmaningar vid mötet med dessa kvinnor i praktiken. Detta är särskilt utmanande i Jamaica, där det rapporteras att det förekommer höga siffror av våld i nära relation, men där olika faktorer inklusive begränsade resurser, sociala och kulturella normer kan begränsa möjligheterna för sjuksköterskor att stödja dessa kvinnor. På grund av begränsad tidigare forskning om ämnet i Jamaica finns det ett behov av ökad kunskap och förståelse om hur sjuksköterskor i Kingston, Jamaica upplevde den vård de ger och hur den påverkar dem.

Caring for the Critically Ill at the End-of-Life : Nurses’ Experiences of Palliative Care in Brazilian ICUs – a Minor Field Study

Tillquist, Maria January 2015 (has links)
Background: Critical care is a relatively young speciality with its intention to treat critical illness equally all around the world. Patients admitted to ICUs receive advanced treatments in order to save lives, however some patients will pass away during critical care, which put family members in great physical and emotional distress. It is important to support family needs and keep core principles of palliative care in mind in order for patients and family members to cope with current situation. The need for palliative care is greater than ever, but in most parts of the world it is poorly developed. Brazil struggles with several challenges regarding implementation of a palliative approach within ICU settings. Aim: the aim was to explore nurses’ experiences of palliative care, focusing on family involvement in Brazilian ICUs. Method: semi-structured interviews were analysed using content analysis. Five female nurses were included from one public and one private hospital in the city of Rio de Janeiro, with an average ICU working experience of nine years. Results: three main categories were identified describing nurses’ experiences of palliative care and family involvement: to care for a dignified death, to promote family involvement and areas for future improvement. Discussion: the results reveal that the nurses, even though lack of professional training, believe that palliative care is important for both patient and their family members at the EOL. Brazilian nurses also face several challenges in order to perform palliative care successfully within ICUs. They struggle with strict visiting policy and the perception of nurses being inferior to physicians. There is a wish for acknowledgement of the nursing profession during EOLC in Brazilian ICUs, since nurses spend most time at each patient’s bedside along with their family members.

Competiveness among apparel manufacturers in Istanbul : An industry analysis

Ahlqvist, Pontus, Andréasson, Carl January 2007 (has links)
<p>This paper is the result of a minor field study conducted in Istanbul, Turkey, during the period of November and December 2007. The purpose of the paper is to investigate the current business environment for apparel manufacturing in Istanbul. Research was carried out through an industry analysis in terms of competition and potential future development for apparel manufacturers.</p><p>The research has been carried out through interviews with actors related to the apparel manufacturing segment. Interviewees include five manufacturers, two sourcing agents, one trade organization and one professor with research in the area.</p><p>Our findings concerning the business environment are based on Michael E. Porters theoretical framework on “How Competitive Forces Shape Strategy”. In the case of Turkish apparel manufacturers this paper concludes how the barriers of entry for new actors are high, unless integrating forward. Additionally in general terms the suppliers have a weak bargaining position while customers are relatively strong in the bargaining process. The rivalry among apparel manufacturers is low, but it can be stated how less differentiated manufacturer experience significant higher level of rivalry. Further on this paper also concludes how these factors not are affected by any substitute products, much due to the broad scope of the study.</p><p>In respect to these factors a general strategy used by apparel manufactures has been identified as they try to affect the balance of these competitive forces through e.g. differentiation and vertical integration.</p>

Nurses’ Perspectives and Experiences in Giving Palliative Homecare to Paediatric Patients from Marginalized Communities in Jakarta, Indonesia

Andersson, Veronica January 2019 (has links)
The development of palliative care in Indonesia has been slow due to the absence of palliative care guide lines and standards. This results in the limited provision of palliative care where it can only be found available in 14 hospitals in the whole country with a population over 260 million, and the palliative care is basically directed to adult patients. In the paediatric medicine field, the palliative care services in Indonesia is still in its infancy and currently palliative care is served by only one non-profit organization in Jakarta. With around 1,5 million people in Jakarta associated with living in poverty, this organization is focusing on providing free palliative care to children from marginalized communities. The questions that are raised out of these circumstances are how paediatric palliative care is practiced in Jakarta and what the rewarding and challenging parts of the job are. The aim of the study is to describe nurses' perspectives and experiences in giving home-based palliative care to children living with cancer and HIV from marginalized communities in Jakarta. A qualitative study design with content analysis was considered to be the method that fitted the goal of the study best. Semi structured interview was used as data collection method and there were seven nurses who participated in the interviews. The result is described by two main categories; the first category contains different topics that functioned as encouragements to the nurses, and the second category consists of various subjects that contribute to challenges that nurses encounter in their work. Lack of palliative education that lead to certain attitudes in the referral process, misperceptions about pain management and nurses’ stress management are discussed as some challenges encountered in the implementation of palliative care.

From Minimum Wages to Living Wages? : A case study of the export-oriented garment industry in Bangladesh / From Minimum Wages to Living Wages? : A case study of the export-oriented garment industry in Bangladesh

Wulff, Gabriella January 2009 (has links)
This text will take you on a journey to the Far East – Bangladesh to be more specific. Inspring 2008 I went there to find some answers to the question of wages. I wanted to know if achange in focus from minimum wages to living wages could be achievable. The question willunfortunately remain unsolved at the end of the essay. To predict the future would beimpossible. Instead three possible scenarios are presented. The likelihood of each and everyscenario is later discussed. The conclusions at the end of the essay are based on an analysis ofthe theories presented and the interviews proceeded.The starting point for the research is the relocation strategies of corporations, which areoutlined in the background chapter. This chapter also contains information about the garmentindustry in Bangladesh. The main research question is if there can be a shift from minimumwages to living wages in Bangladesh. In order to bring clarity to the question, three subquestions have been used. The first question looks into how wages are determined in theexport-oriented garment industry in Bangladesh. The second question concerns thecorporations’ responsibility for their workers. The third, and last, question addresses howcultural dimensions influence the corporations and how wages are set. To find the answers tothe sub questions I divided the research into four main topics: “Wages – Minimum and LivingWages”, “Morality, Ethics and Business Ethics”, “Employees as Stakeholders of theCompanies” and “The Cultural Dimension”. The topics are dealt with in separate chapters.The chapters contain a theoretical overview, as well as the information gathered from theinterviews.The chapters are followed by a further analysis of the empirical findings. The chapter onwages contains an in-depth explanation of the difference between minimum wages and livingwages. In the conducted study all workers were paid the minimum wage in coherence with thelaw. This wage was however much lower than what the definition of a living wage declares.Therefore many workers did over-time in order to reach a higher standard of living. Businessethics and the stakeholder theory will be used to discuss the opportunities and limitations ofthe responsibility of the corporations for their workers. The scholar Hofstede’s system ofmeasuring national cultural values will be used to look into specific cultural aspects.According to his system, Bangladesh has a high ranking in power distance, a low ranking inindividualism and a middle ranking in masculinity. These three dimensions will be discussed;both correlations and exceptions found in this study will be presented.The three possible scenarios for a change are presented in the conclusions. Firstly, theminimum wages could be changed into living wages, if the government decides on raising thewages of the garment workers. Secondly, the mentality amongst management could provide asolution to the change in focus. If managers could find advantages in paying their workersmore, it would open up for a brand new wage system. Thirdly, changes could come from theworkers themselves, through unification in the regard. This has however been valued as lesslikely to happen, because of the power distance prevailing in the country. / Program: Textilekonomutbildningen

Thinking about Disabilities in a Primary Inclusive Education Class in Vietnam

Bergstad, Johan, Granli, Johan January 2004 (has links)
<p>This Minor Field Study was undertaken in theoutskirts of Hanoi, Vietnam during September and October 2003. The aim was to explore what 10-11 year old primary school children think about disabilities in an Inclusive Education class, i.e. a class with non-disabled children and children with disabilities (CwD). Sixteen children, including four CwD, were interviewed in a semi-structured way. The children mentioned physical disabilities more often than "mental" or "learning" disabilities even though three of the CwD had those kinds of disabilities. More than half the sample seem to think about war-related causes of disabilities. Many interviewees also mentioned that other children treat CwD both "well" and "badly". Some girls and no boys mentioned that they feel sympathy for and want to help persons with disabilities. One-fourth of the children seem to think of disabilities as a deviation.</p>

Conditions for Successful Export : An Analysis of Bolivian Wooden Door Producers

Rosén, Malin, Lindmark, Monica January 2006 (has links)
<p>Bolivia, as the poorest country in South America, can gain a lot from international trade. It is an important factor for a country to build prosperity and gain economic growth and thereby reach a higher standard of living. But for a company to succeed in the international market is a demanding task. Both internal and external factors that influence a company’s competence need to be taken into consideration. This Master Thesis deals with two Bolivian wooden door producers’ possibilities to export to the Swedish market.</p><p>The demand of tropical wood products is expected to increase and the Bolivian wood industry has been identified as an export industry of the future. Another thing in favor for the Bolivian export is the fact that the country is number one in the world when it comes to sustainable management of forest resources. This gives the companies the possibility to offer an environmentally friendly and unique product and thereby create competitive advantages. There are though areas that need improvement. One of the most important improvement areas for both of the companies is marketing and understanding what the customers needs. They need to keep the costumer in focus in all of their activities and learn how to promote their products advantages.</p><p>The facts that both the studied companies have earlier experience in export and a high level of motivation support the possibility to succeed in this matter. But, these factors are not enough for the studied companies to succeed in export. The result of this study also shows that the instable situation in the country results in financial problems and lack of trust. Therefore the companies must focus on building trust to attract new customers and</p><p>investors. This should be done by keeping an even level of quality, fulfilling promises and finding ways to reduce the risk for potential investors.</p><p>The trend towards more individual and exclusive doors in the Swedish market results in the recommendation to focus on offering a niche product in the middle-price segment. It is also recommended for the Bolivian companies to use some kind of representative to reach the market. A good alternative is to work as a supplier to a door producing partner and help them widen their assortment and in turn get someone present in the market that can work close to the customers.</p>

Tiyeseko : A Study on Small-Scale Farming Women in Sustainable Agriculture in Zambia

Johansson, Karin January 2003 (has links)
<p>The purpose of this study is to understand what impact courses in sustainable agriculture have had on small-scale farming women in Zambia, who have started using alternative techniques in their farming. Weather conditions, political issues and other circumstances in Zambia have made it difficult for people to grow enough crops to feed their families and gain extra money alternative methods are being promoted by organisations at all institutional levels, in order for people to survive. At Kasisi Agricultural Training Centre, east of the capital, Lusaka, sustainable methods in farming practices are taught to small-scale farmers. It is a qualitative study, accomplished within the field of Human Geography, and the theoretical frameworks that have been used are political ecology of sustainability, low-external input in sustainable agriculture, and gender and development. The qualitative methods used are in accordance to Rapid Rural Appraisal, where small-scale farming women have been interviewed on a semi-structural basis. Additionally, secondary data in the form of literature has been gathered and direct observations have been made in the field. Results show that the courses in sustainable agriculture have had an impact on the lives of participating small-scale farming women and that they are able to spread their knowledge to neighbouring small-scale farmers. It also shows that politics has a major influence on the daily life of the women.</p>
