Genom fluglarvskompostering erhålls biomassa från organiskt avfall samt en näringsrik behandlingsrest som kan användas som gödningsmedel eller för biogasutvinning. Larvbiomassan kan användas som djurfoder eller för att tillverka biodiesel. Eskilstuna Strängnäs Energi och Miljö AB planerar bygga en pilotanläggning för fluglarvskompostering med larver av den amerikanska vapenflugan (Hermetia illucens). Behandlingen ska ske i lådor staplade på varandra, avskilda med ett mellanrum för att tillåta luftning av materialet. Luftningsbehovet utgörs av larvernas syrebehov samt av att transportera bort fukt och värme från materialet. Syftet med det här projektet var att utvärdera luftningsbehovet under fluglarvskomposteringsbehandling av matavfall med staplade behandlingslådor. Först designades ett experimentskåp att utföra experimenten i och därefter ett ventilationssystem till skåpet. Två experiment utfördes där tre staplar med nio behandlingslådor vardera utvärderades. I experiment I användes totalt 15 kg matavfall och 15 000 larver per behandlingslåda, i experiment II användes 11 kg matavfall och 10 000 larver per behandlingslåda. Under experimenten togs prover för torrsubstans (TS) och glödförlust (VS), pH samt tillväxt av larverna. Sensorer mätte lufttemperatur, relativ luftfuktighet och materialtemperatur. I båda experimenten erhölls en behandlingsrest med betydligt lägre TS-halt än önskat, vilket troligtvis berodde på att luftflödet i experimentskåpet var lägre än beräknat. I experiment I evaporerade i genomsnitt 6,2 kg vatten per behandlingslåda och i experiment II 4,8 kg, vilket för båda experimenten motsvarade cirka 50 % av det med matavfallet tillsatta vattnet. Enligt resultaten av experimenten kan torrsubstansen av matavfallet reduceras med runt 60 %. Runt 32 % av torrsubstansen i matavfallet omvandlades till larvbiomassa. Materialtemperaturen var i genomsnitt 27–30 °C under experimenten. Lufttemperaturen i experimentskåpet var 27–28 °C och 31 °C i inluften. Den relativa luftfuktigheten i experimentskåpet var 59–67 % och 36 % i inluften. Baserat på resultaten krävs ett luftflöde på 8,4 m3/h per behandlingslåda för att nå en TS på 50 % i behandlingsresten om matavfallet har en TS-halt på 15 %. Baserat på resultaten är ett nedåtriktat luftflöde att föredra framför uppåtriktat i de fall ett vertikalt luftflöde används. Skillnader i temperaturer och luftfuktighet indikerade dock att det vertikala, nedåtriktade, luftflödet inte kunde förse alla behandlingslådor i staplarna med samma luftflöde. På grund av detta kan det vara lämpligt att överväga ett horisontellt luftflöde i containern i vilken behandlingen ska ske. Vidare kan det vara fördelaktigt att reglera vattenhalten i matavfallet så att stora variationer i luftningsbehov undviks eller reglera luftflödet efter vattenhalt i ingående matavfall. Inför val av ventilationsdesign rekommenderas fortsatta studier av hur höga luftflöden påverkar behandlingen. / Larvae of the Black Soldier Fly (Hermetia illucens) can convert organic waste into biomass. The residue is nutrient-rich and can be used as fertilizer or for biogas production. The aim of this study was to assess the aeration need for designing a ventilation system in a pilot plant for larvae composting in Sweden. First, a cabinet with required ventilation arrangement for performing the experiments was designed. Two experiments were performed, where three stacks each comprised of nine boxes with spacers were used. In the first experiment, a total of 15 kg of municipal food waste and 15 000 larvae were used per box. In the second experiment, a total of 11 kg food waste and 10 000 larvae were used per box. In the first experiment 6.2 kg of water evaporated per treatment box and in the second 4.8 kg, both corresponding to about 50 % of the water present in the substrate added. An average temperature of 31 °C in the inlet air resulted in temperatures of 27-30 °C in the material during the treatment. Based on the results, 8.4 m3/h of air is needed per treatment box to reach 50 % dry matter in the residue of food waste containing 15 % dry matter. The results also indicate that to reach the desired water content in the residue, there might be a need to adjust the initial water content in the food waste and use horizontal airflow in the treatment container. Before deciding on a ventilation design, further studies are necessary to assess how high airflows affect the treatment.

A Child in an Armed Conflict in the Light of Article 38 of the Convention on the Rights of the Child The thesis aims to transparently elaborate the topic of protection of children in armed conflicts pursuant to the Article 38 of the Convention on the Rights of the Child as well as identification of the main problems associated with the topic and efforts to suggest their solutions. The thesis also focuses on monitoring and enforcement mechanism of individual international instruments. The body of the thesis is divided into four parts, each of several chapters. The first part of the thesis deals with the development of protection of children in armed conflicts until the adoption of the Convention on the Rights of the Child, and relevant international law documents on the protection of children in armed conflicts. The first part also includes a chapter with the identification of the main problems associated with the protection of children. Second part of the thesis concentrates on the analysis of various instruments of international law regarding the protection of children, that is, of course, the Convention on the Rights of the Child and its Optional Protocols, and following documents regarding protection of children based on this Convention, i.e. The Convention of the International Labour Organization...

Dans la plupart des situations de guerre utilisant des enfants, tout au moins dans les configurations actuelles, c’est une partie du groupe-communauté lui-même qui porte la transgression. Il apparaît souvent dans ces guerres une dimension inavouable liée à la dynamique interne du groupe. Dans ces configurations il s’agit d’une organisation collective du massacre par une partie du groupe, sur la base de codes communs et partagés saisissable au travers de la théorie des catastrophes (Thom, 1961) comme des opérateurs de bifurcation. Comme si d’une part, la figure de l’intrus (Duez., 2003) qui peut se comprendre comme produit du travail de figuration, de mise en forme de l’objet perdait sa principale fonction structurante, et d’autre part, le sujet perdait toute possibilité de vivre intimement le groupe comme son espace psychique, comme la scène destinée à transférer immédiatement ses différents conflits et enjeux psychiques, re-convoquant les scénalités archaïques et invitant à définir de nouvelles formes à investir. Ceci vient complexifier tout travail de symbolisation. Dans ces contextes de transgressions, où l’enfant est au prise avec l’autre-semblable devenu nocif et porteur de la mort, l’émergence de la figure de l’enfant-soldat obéit à une dynamique dont la force (celle utilisée par le chef de guerre) n’est pas le seul paramètre. Cette figure est logée dans le groupe-combattant qui est une émanation méta-défensives du groupe-communauté. / In most current configurations of war front using children, we use to find a part of the community-group bearing itself the transgression. It often appears in these wars, a shameful dimension related to the internal dynamics of the group killing itself. By the fact, in these configurations, we have a collective massacre committed by part of Group, on the basis of common and shared social rules and anthropological codes. The catastrophe theory (Thom, 1961) is an opportunity to explain those phenomena using attractive and repulsive forces in individual an groupal catastrophic bifurcation. It seems, on one hand, the “alien intrusion” (Duez B. 2003) which can be considered as the result of the psychic figuration work out and shaping of the psychic object, loses its main structuring function. On the other hand, the individual lost any opportunity to intimately experience the group as a psychic area on which he can transfer his immediate psychic conflicts and issues. Then, archaic scenes take the rule and invite the individual to find new internal form to deal with for symbolisation process. In these transgressions contexts, where children have to deal with harmful adult bearer of death, the rising of Child Soldier phenomena obeys a dynamic in witch strength (used by lord of war) is the common but not the unique parameter to consider. Child Soldier emerge in the war group which is a meta-defensive organization of the community reacting to the state of war.

The intention of this thesis is to identify and analyze the precise shift from an exploitative archetype to an empowered representation of women warriors, to identify the arena in which male and female characters are given equal agency in the context of war, and finally explore the key characteristics that make up an empowered female hero. This thesis also addresses the sociocultural nature of the warrior woman archetype as it pertains to the current role of women in the military. The films analyzed in this thesis are all post 9/11 films; a fact that links them culturally to the wars in Iraq and Afghanistan. In recent years, numerous milestones have been reached for women in the armed services, especially for those women in combat positions. For the first time in American history women are being recognized for their active role as soldiers in combat. Therefore, it is valid to consider the correlation between seeing women as military professionals, fighting alongside male soldiers in these films, and the cultural impact of female combat soldiers. This aspect of the thesis also imbues the female just-warrior archetype with a legitimate history, mythology, and current cultural reference; which is essential to the visibility of female combat soldiers of the 21st century.

This thesis is a case study aimed at a key argument in the emerging field of Civil War medical and environmental history. While historians have long acknowledged disease as a major killer during the Civil War, only recently have environmental and medical historians turned their collective attentions to unpacking the complex interconnections of disease, environmental conditions, and culture. By examining the 58th North Carolina Infantry Regiment from the mountains of western North Carolina, this thesis asserts that the combined role of the disease environment and conditions in military camps created the massive outbreaks of disease that characterized the seasoning process of the regiment. Furthermore, the soldiers were practical in their response to conditions, weighing family, nation, and other factors in the face of death. When the threat of disease combined with personal and other factors, many soldiers deserted or took other actions of self-preservation over loyalty to the Confederacy.

The thesis From the military to civilian life: the vocational identity of former soldiers of the ACR presents a qualitative research focused on the issue of transition from the military to the civilian environment. Based on research interviews with 28 informants from the ranks of former soldiers of the Czech Armed Forces, the author explains how the degree of identification with the army among former soldiers is related to the process of forming a new civilian identity and how the circumstances of their transition shape the formation of professional identities. The thesis also identifies the problems and concerns that departing soldiers face in the process of transitioning from the military to the civilian environment, and where the whole issue of transition between the two environments stems from. Within the research, space is also devoted to the related issue of preparing soldiers for the transition to the civilian environment. Based on the experiences of former soldiers, the process of preparing soldiers for employment in the civilian labour market and the approach of the military to this matter is explained. To make the research more objective, the author also answers the research questions concerning the strategies for supporting soldiers transitioning to the civilian environment and in...

En 1996, la conscription universelle est remplacée par une nouvelle forme d'organisation militaire, l'engagement volontaire. On assiste alors à la professionnalisation des institutions militaires, puisque les soldats qui les composent ne sont plus appelés, mais ont choisi de s'engager dans l'armée, la considérant comme une voie professionnelle possible. Dès lors, la question de l'appréhension de l'activité militaire en tant que métier comme les autres se pose. Peut-on vraiment considérer le métier de militaire comme ceux qui peuvent être exercés dans le monde civil ? Et peut-on procéder à une analyse des conditions de travail et à une prévention des risques psychosociaux potentiellement présents de la même façon que dans le monde civil ? Cette dernière interrogation va constituer tout l'enjeu de notre recherche. Pour répondre à ces questions, nous nous sommes intéressés à la spécificité militaire, que nous avons définie et examinée au cours d'une étude sur les représentations sociales du métier de militaire. Les résultats de cette étude permettent alors de comprendre qu'il existe un certain nombre d'éléments caractéristiques du métier de militaire qui, s'ils sont coprésents, ne caractérisent que le métier de militaire, autrement dit, le rendent spécifique par rapport aux autres métiers. Nous nous sommes ensuite concentrés sur les raisons de l'engagement dans l'Armée de Terre et l'implication des militaires une fois engagés. Une nouvelle étude a été menée et nous a permis de distinguer différentes raisons à l'engagement en fonction l'époque à laquelle se sont engagés les militaires interrogés. Des différences d'implication dans le travail ont également été observées. Les résultats observés lors des deux premières études nous ont permis de conclure que le métier de militaire ne pouvait pas être appréhendé de la même façon que les autres métiers. Pour prévenir les risques psychosociaux spécifiques à ce métier, il fallait donc des outils de détection qui soient propres aux caractéristiques de l'institution. En dernière partie de cette recherche, nous avons donc créé un outil de détection des risques psychosociaux militaires, autour des éléments caractéristiques mis en évidence lors des précédentes études. L'outil a été testé et un premier diagnostic sur une population de plus de 2000 militaires a été réalisé. / In 1996, the universal conscription has been replaced by a new form of military organization: the voluntary enlistment. Then, the professionalization of the military institutions appears, soldiers are not conscripted anymore, but choose to enlist in the French Land Army, considering it as a possible career path. Therefore, the apprehension of the military profession as a common profession may be questioned. Can we really consider the military profession as a profession practiced in the civilian sphere? Can we analyze work conditions and prevent the psychosocial risks in the same way as for the other professions? This last question constitutes the real challenge of our research. In order to answer these questions, we took an interest in the military specificity that we defined and examined during the course of a study about social representations of the military profession. The results are useful to understand that a set of elements characterizing the military profession exists, and these elements, if they are co-present, could characterize only the military profession and thus make it specific compared to the other professions. Then, we focused on the soldiers' reasons to enlist in the French Land Army and their involvement once they are enlisted. Another study has been conducted and allowed us to distinguish different reasons for enlistment depending on the time the soldiers enlisted themselves. Differences in terms of involvement have also been observed. The results we have observed in the two first studies made us conclude that the military profession cannot be apprehended in the same way as for the other professions. To prevent the psychosocial risks that are specific to the military profession, we needed detection tools that were particular to the military institution. In the last part of this research, we created a detection tool for the military psychosocial risks, using the elements highlighted in the previous studies. The tool has been tested and a first diagnostic in a population of 2000 militaries has been realized.

The result was , among other things , to determine what strategies are used by soldiers to provide their housing and commuting . Other findings are described in the empirical part and at the end of the thesis. Powered by TCPDF (www.tcpdf.org)

Förenta nationerna förutser en global befolkningsökning med 2 miljarder människor till 2050, vilket motsvara en total befolkningsmängd på nära 10 miljarder människor. Dessutom förväntas ökningen ske oproportionerligt över jorden och koncentreras i delar av världen där livsmedelssäkerheten är låg och produktionen otillräcklig. FN:s livsmedels- och jordbruksorganisation (FAO) uppskattar att det kommer krävas en produktionsökning med 70% för att möta livsmedelsbehovet för den globala populationen. Att odla fisk som alternativ till konventionellt fiske är en möjlighet att möta den ökande efterfrågan på animaliskt protein då de naturliga fiskbestånden minskar. Akvaponiska odling är ett kombinerat odlingssystem av hydroponisk odling och vattenbruk som möjliggör minskade risker kopplade till övergödning och smitning. Dock är fiskodlingarnas konsumtion av foderfisk problematisk. Insekter är ett av många foderalternativ som ofta nämns som en klimatsmart lösning då insekter är platseffektiva att odla och har en hög förmåga att omvandla biomassa till högvärdigt protein. En art som fått extra mycket uppmärksamhet inom detta område är den amerikanska vapenflugan (Hermetia illucens). Syftet med denna studie var att undersöka om implementeringen av ett insektsbaserat fiskfoder med vapenflugelarver kan sänka klimat- och miljöpåverkan från en fiskodling jämfört med att använda ett konventionellt fiskfoder baserat på ingredienser från vildfångad havsfisk. Detta har gjorts genom utförandet av en litteraturstudie av det konventionella fiskfodret och en livscykelanalys av larvproduktionens påverkan inom dessa fyra miljöpåverkansindikatorer: total energianvändning, klimatpåverkan (GWP), foderfiskkonsumtion (FIFO) och försurning. Resultatet av studien visade att det framförallt är lokalen för produktionen som konsumerar energi för uppvärmning, ventilation och belysning. Utöver detta visade sig bearbetning av larverna (torkning) vara en energiintensiv process. Från klimatperspektiv är det själva komposteringsprocessen som förorsakar de största enskilda utsläppen av växthusgaser. Resultatet visar vidare att produktionen av den amerikanska fluglarven presterar bättre för de studerade faktorerna än det konventionella fiskfodret och att den således har potential som foderkomponent. Fallstudien visar att den undersökta akvaponianläggningen kan minska sin påverkan inom samtliga effektkategorier jämfört med ett nyttjande av konventionellt foder. Dock är studiens utfall beroende av vilka förutsättningar som finns gällande produktionens geografiska placering och således vilken elmix som nyttjas samt vilken tillgången är på lämpliga substrat såsom matsvinn. / The United Nations foresees a global population increase of 2 billion people by 2050, corresponding to a total population of nearly 10 billion people. In addition, the increase is expected to be disproportionate over the earth and concentrated to parts of the world where food safety is low and production insufficient. The Food and agriculture organization of the United Nations (FAO) estimates that a production increase of 70% will be required to meet the food needs of the global population. Growing fish as an alternative to conventional fishing is an opportunity to meet the increasing demand for animal protein as the natural fish stocks decrease. Aquaponics is a combined cultivation system of hydroponic cultivation and aquaculture that reduces risks associated with eutrophication, invasive species and diffusion of antibiotics and chemicals. However, the consumption of feed fish is problematic in in both traditional aquaculture and in aquaponic cultivation. Insects are one of many feed alternatives that are often referred to as a climate-smart solution since they are effective to grow from a land use perspective and have a high ability to convert biomass into high-quality protein. One species that has received extra attention in this area is the black soldier fly (Hermetia illucens). The purpose of this study has been to investigate whether the implementation of an insect-based fish feed with black soldier fly larvae can reduce the environmental impacts of an aquaponic cultivation farm compared to using conventional fish feed based on ingredients from wild-caught sea fish. This has been done by carrying out a literature study of the conventional fish feed and a life cycle analysis of the influence of larva production within these four environmental impact indicators: total energy use, climate impact (GWP), feed fish consumption (FIFO) and acidification. The results of this study showed that the main energy use for the production of larvae is energy for heating, ventilation and lighting of the production location. In addition, the processing of the larvae (drying) was showed to be an energy intensive process as well. From a climate perspective, it is the composting process carried out by the larvae that causes the largest individual emissions of greenhouse gases. The result also shows that the production of the black soldier fly larvae performs better within the four environmental impact indicators than the conventional fish feed and thus it has the potential as a more sustainable feed component. The case study shows that the analyzed aquaponic farm can reduce its impact in all studied impact categories compared to using conventional feed. However, the study's outcome depends on the current circumstances regarding geographical location of the production, the electricity mix used as well as the availability suitable substrates such as food waste.
