I Fängelset : Regler och disciplinära åtgärder mot internerna på Falu fångvårdsanstalt under 1900-1905 och 1950-1955

Syftet med denna C-uppsats är att se vilka förändringar som ägde rum på Falu fångvårdsanstalt mellan två skilda perioder. Fokus ligger på de disciplinära åtgärder som vidtogs mot fångar som på något vis misskött sig på anstalten. Ena perioden är mellan 1900-1905 och den andra perioden är mellan 1950-1955. Under 1946 ägde en reformering av Svenska fångvården rum. Före detta år satt internerna isolerade i ensamceller och fick varken träffa eller språka med någon annan fånge under sin fängelsevistelse. Efter 1946 trädde reglementeringen i kraft där fångarna fick träffa varandra och samtala. Interner erhöll mer frihet än innan och den strikta ordning som funnits innan avtog så smått. Frågan som ställs i arbetet är vilka förändringar som går att finna före och efter 1946 års reglementering. Fången fick mer frihet efter detta år, men paradoxalt nog ökade skötsamhetsöverträdelserna efter 1946. De disciplinära åtgärderna fördubblades nästan i jämförelse med tidigare period. Det ökade förtroendet för internerna renderade i en högre grad av oordning på Falu fängelse och resultatet av undersökningen visar att det förekom fler förseelser 1950-1955 än 1900-1905. Källmaterialet till undersökningen består i huvudsak av förhörsprotokoll och straffjournaler från Falu fängelse för angiven tid, vilka har studerats på landsarkivet i Uppsala.

O campo de energia elétrica no Brasil - de 1880 a 2002

Since electric power is an essential element in modern society, this paper analyzes the historic and institutional factors that have contributed to the formation and organization of the Brazilian electric sector, from the time when it started to be used in this country until the end of year 2002. This analysis is based on a linear description of historic facts, giving emphasis to crucial events ¿ or critical incidents, as they were called for the purpose of this paper. As to these happenings, the social actors who played an important role in the development of the Brazilian electric power sector were analyzed. An analytical model based on the theoretical references offered by the Institutional Theory was used. The study also highlights the elements that comprehend the development of the phenomenon in face of the ambivalence existing in a developing country, which is the case of the Brazilian electric power sector. The organizational fields that were established at the time determined by the main crucial incidents presented throughout the length of time covered by this study. The resources that the main social actors involved in the electric power sector may use by are also identified, as well as their main interests and level of influence these actors may have. Several documents were analyzed. The qualitative methodology was used. Also, many semi-structured in-depth interviews of the people who have made the history of this sector for reliability were conducted. Finally, this study includes the main elements that have shaped the institutional model of the Brazilian electric sector. It also characterizes the external environment as the element which has most influenced the sector and has also led its way throughout the different developmental phases, especially with respect to funding. The growing rates of power consumption indicate the need for a constant increase in the supply of electric power to meet the needs of society and economic development. This requires constant investment. Lack of investment is a limiting factor. Not only does it hinder the development of the country but it may also result in very unfortunate mishaps such as electric power rationing, such as the kind we had to endure a while ago.

Atividades antinociceptiva e anti-inflamatória de uma fração rica em heterogalactana sulfatada extraída da alga codium isthmocladum (vickers 1905)

Sulfated polysaccharides comprise a complex group of macromolecules with a range of several biological activities, including antiviral activity, anticoagulant, antiproliferative, antiherpética, antitumor, anti-inflammatory and antioxidant. These anionic polymers are widely distributed in tissues of vertebrates, invertebrates and algae. Seaweeds are the most abundant sources of sulfated polysaccharides in nature. The green algal sulfated polysaccharides are homo or heteropolysaccharides comprised of galactose, glucose, arabinose and/or glucuronic acid. They are described as anticoagulant, anti-inflammatory, antiviral, anti-angiogenic, antitumor compounds. However, there are few studies about elucidation and evaluation of biological/pharmacological effects of sulfated polysaccharides obtained from green algae, for example, there is only one paper reporting the antinociceptive activity of sulfated polysaccharides of these algae. Therefore this study aimed to obtain sulfated polysaccharides of green seaweed Codium isthmocladum and evaluates them as potential antinociceptive agents. Thus, in this study, the total extract of polysaccharides of green alga C. isthmocladum was obtained by proteolytic digestion, followed by fractionation resulting in five fractions (F0.3, F0.5, F0.7, F0.9 and F1.2) by sequential precipitation with acetone. Using the test of abdominal contractions we observed that the fraction F0.9 was the most potent antinociceptive aompound. F0.9 consists mainly of a sulfated heterogalactana. More specific tests showed that Fo.9 effect is dose and time dependent, reaching a maximum at 90 after administration (10 mg / kg of animal). F0.9 is associated with TRPV1 and TRPA1 receptors and inhibits painful sensation in animals. Furthermore, F0.9 inhibits the migration of lymphocytes induced peritonitis test. On the other hand, stimulates the release of NO and TNF-α. These results suggest that F0.9 has the potential to be used as a source of sulfated galactan antinociceptive and anti-inflammatory
