Junior.pdf: 1045163 bytes, checksum: d759d4bffb13bbf9696edda30c7326f2 (MD5) Previous issue date: 2015-12-02 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The determination of digestible lysine requirements for Nile tilapia is essential to adjust the correct balance of amino acids in it?s food. Lysine is the amino acid reference for studies in ideal protein, which is currently an important concept in animal nutrition once it allows a reduction in the protein amount of the diet without compromising performance, and furthermore reducing the nitrogen excretion and eutrophication risks of the water. This study aimed to determine the digestible lysine requirement for Nile tilapia in the final phase of growth (500 to 600 g of body weight). Isocaloric and isoproteic experimental diets were utilized with different levels of digestible lysine in each formulation. The amounts of L-lysine HCl 78% used were 0.000; 0.388; 0.776; 1.164, and 1.552% replacing the ingredient glutamic acid 99%; which adjust the treatments to 0.932; 1.23; 1.53; 1.83, and 2.14% of digestible lysine. Nile tilapia weighing 519 g making a sum of 300 animals were utilized in this experiment. They were distributed in 25 water tanks each one measuring a 1000 liters using a renewable system of water. The pH, dissolved oxygen, temperature, salinity and conductivity were monitored daily and ammonia was measured weekly. Slaughters happened when fishes reached 28 and 50 days counting from the beginning of the experiment. The following animal science aspects were evaluated at the end: weight gain (WG), daily weight gain ratio (DWGR), specific growth rate (SGR), food intake (FI), consumption of digestible lysine (CDL), food conversion (FC) protein efficiency gain (PEG), lysine efficiency gain (LEG), nitrogen retention efficiency (NRE), protein deposition rate (PDR), Daily fat deposition rate (DFDR), protein retention efficiency (PRE), and survival rate (SR). The data was interpreted by analysis of variance with 5% probability. There was quadratic effect for GP, CA, TCE, ELG, EPG. The estimated value of lysine for both the largest GP and the best CA is 1.31% digestible lysine. There was no significant differency regarding the food intake, carcass or filet characteristics. This result is in part due to the fact of the gain being proportional throughout the body of the fish. In the second slaughter were obtained quadratic effect in the ether extract and carcass moisture. The Nile tilapia in the weight range of 500 to 600 grams of body weight presents the requirement for 1.31% of digestible lysine, corresponding to 5.31% of digestible dietary protein and 0.431% per Mcal of digestible energy for greater weight gain and better food conversion in it?s experiment conditions / A determina??o da exig?ncia de lisina para a til?pia-do-Nilo ? importante para a elabora??o de ra??es com adequado balanceamento de amino?cidos. A lisina ? o amino?cido refer?ncia nos estudos de prote?na ideal, um conceito relevante atualmente uma vez que permite a redu??o na quantidade de prote?na da ra??o sem comprometimento do desempenho, diminuindo ainda a excre??o de nitrog?nio para a ?gua e o risco de eutrofiza??o. O presente trabalho objetivou determinar a exig?ncia em lisina digest?vel para a til?pia-do-Nilo na fase de 500 a 600 g de peso vivo. Foram utilizadas dietas experimentais que consistiram em ra??es isocal?ricas, isoproteicas e com valores crescentes de lisina digest?vel. A L-lisina HCl 78% foi utilizada com valores crescentes (0,000; 0,388; 0,776; 1,164 e 1,552%), em substitui??o ao ingrediente ?cido glut?mico (99%), perfazendo os tratamentos com 0,932; 1,23; 1,53; 1,83 e 2,13% de lisina digest?vel. Foram utilizadas 300 til?pias-do-Nilo com peso m?dio de 519 g e distribu?dos em 25 caixas d??gua de 1000 L em sistema aberto de circula??o de ?gua. O pH, oxig?nio dissolvido, temperatura, salinidade e condutividade da ?gua foram monitorados diariamente e a am?nia foi medida semanalmente. Foram realizados 2 abates, aos 28 dias e aos 50 dias de experimento. Foram avaliados os seguintes ?ndices zoot?cnicos: ganho de peso (GP), ganho de peso di?rio (GPD), taxa de crescimento espec?fico (TCE), ingest?o alimentar (IA), consumo de lisina digest?vel (CLD), convers?o alimentar (CA), efici?ncia proteica para ganho (EPG), efici?ncia de lisina para ganho (ELG), efici?ncia de reten??o de nitrog?nio (ERN), taxa de deposi??o de prote?na (TDP), taxa de deposi??o di?ria de gordura (TDG), efici?ncia de reten??o de prote?na (ERP) e taxa de sobreviv?ncia (TS). Os dados foram interpretados por meio de an?lise de vari?ncia a 5% de probabilidade. Houve efeito quadr?tico para GP, CA, TCE, ELG, EPG, sendo o valor estimado de lisina tanto para o maior GP quanto para a melhor CA de 1,31% de lisina digest?vel. N?o houve diferen?a significativa para o consumo de ra??o, rendimento de carca?a, rendimento de fil?, caracter?sticas da carca?a e do fil?. Esses resultados se devem em parte ao fato do ganho ter sido proporcional em todo o corpo do peixe. No segundo abate houve efeito quadr?tico no extrato et?reo e na umidade da carca?a. A Til?pia-do-Nilo na faixa de peso de 500 a 600 gramas de peso vivo apresenta a exig?ncia de 1,31% de lisina digest?vel, que corresponde a 5,31% da prote?na digest?vel da dieta e a 0,431%/Mcal de energia digest?vel para o maior ganho de peso e melhor convers?o alimentar nas condi??es deste experimento.

Jag är normal fast annorlunda : Att leva med cystisk fibros

Ganis, Alexander, Freidenfelt, Sara January 2014 (has links)
Bakgrund. Föräldrar upplever oro över att cystisk fibros ska få deras barn att uppleva sig annorlunda. På grund av en långvarig relation upplever sjuksköterskor det känslomässigt krävande att vårda en patient med cystisk fibros i livets slutskede. Problem. Få kunskap om den som är drabbad av CF upplever att sjukdomen är ett hinder för att leva. Syfte. Beskriva upplevelser av att leva med cystisk fibros. Metod. En kvalitativ ansats har använts i form av en litteraturstudie med beskrivande syntes av publicerade artiklar. Resultat. Det framkommer att människor med cystisk fibros har varierande upplevelser av begränsningar och autonomi. De upplever sig som normala utifrån sin livsstil samtidigt som de känner sig annorlunda. Ungdomar upplever svårigheter i vardagen och genomgår en process för att acceptera sjukdomen som en del av livet. Att uppleva ansvar över sin vård och sitt liv skapar upplevelse av självständighet vilket underlättar för den drabbade att uppleva sig som normal. Slutsatser. Det är svårt att acceptera ett liv med CF, den drabbade upplever sig som annorlunda samtidigt som de kämpar för att uppleva sig som normala. Ytterligare forskning behövs om vårdrelationen mellan sjuksköterska och patienten som är drabbad av CF. / Background. Parents experience concern because cystic fibrosis will make their children experience themselves different. Because of a lengthy nurse-patient relationship the nurses‟ experience it is emotionally demanding to care for a patient with cystic fibrosis in the final phase of life. Problem. To get knowledge if the one affected by cystic fibrosis experience that the disease is an obstacle in life. Purpose. To describe experiences of living with cystic fibrosis. Method. A qualitative approach was used in the form of a literature study with a descriptive synthesis of published articles. Results. It appears that people with cystic fibrosis experience varied perceptions of limitations and autonomy. They experience themselves as normal as seen from their lifestyle at the same time as they felt different. Young people experience difficulties in their everyday life and go through a process of accepting the disease as a part of life. To experience responsibility over your care and life creates an experience of independence which makes it easier for the ones‟ affected to experience themselves as normal. Conclusions. It is difficult to accept a life with cystic fibrosis, the affected ones experience themselves as different at the same time as they struggle to experience themselves as normal. Further research is needed about the nurse-patient relationship between the nurse and the patient that is affected by cystic fibrosis.

Die Abschlussphase von Psychotherapien : Untersuchung zur Gestaltung der Abschlussphase psychotherapeutischer Behandlungen / Termination phase of psychotherapeutic treatments : Structure and principles of ending psychotherapeutic treatments

Wittorf, Susanne 15 September 2000 (has links)
Die Beendigung von Psychotherapien ist ein historisch vernachlässigtes Thema, das weitgehend ausgeblendet wurde aus der theoretischen und pragmatischen Konzeptualisierung von Psychotherapie und deren Erforschung. Begriffe wie Abschluss, Ende und Abschied, die mit dem Ende von Therapien verbunden sind, verweisen in unserer Kultur auf Un-Themen. Sie bedrohen mit ihrer assoziativen Verbindung zu Tod eine wesentliche Grundlage unserer normalen Wirklichkeit: die Verleugnung unserer Endlichkeit. Unter Berücksichtigung von Regeln und Normen der Alltagskommunikation für die Beendigung sozialer Situationen beinhaltet die Abschlussphase ein belastendes Potential für Therapeuten und Klienten. Die Beendigung von Psychotherapien wird in Therapiemanualen und Lehrbüchern entweder gar nicht erwähnt oder erstaunlich marginal behandelt. Dabei zeigen sich teilweise einseitige Konzeptualisierungen. So thematisieren tiefenpsychologische Ansätze vor allem Aspekte der Trennung des Therapeuten und des Verlustes der therapeutischen Beziehung, während verhaltenstherapeutische Ansätze fast ausschließlich Fragen des Transfers von Therapieergebnissen in den Alltag nachgehen. Elemente der Abschlussphase werden auf der Grundlage einer Befragung von Psychotherapeuten und Klienten empirisch erkundet. Dabei werden erstens Abschlüsse konkreter Therapien (formale Charakteristika, Veränderungen der Kommunikation in der Abschlussphase, Perspektiven von Therapeuten und Klienten, Katamnese, Supervision) dokumentiert und zweitens allgemeine Aspekte der Therapiebeendigung (Themen der Beendigung, Unterbrechungen im Laufe von Therapien, Grundsätze von Therapeuten) beschrieben. Empirisch zeigt sich die Abschlussphase als eine Zeit am Ende von Therapien, die in der Regel beginnt, wenn deutliche Verbesserungen von therapierelevanter Symptomatik eingetreten sind, die 10 bis 20 % der Gesamtstundenzahl umfasst und die durch spezifische Veränderungen formaler und inhaltlicher Gestaltung der Therapie gekennzeichnet ist. Auf der Grundlage von Ergebnissen einer metaphernanalytischen Auswertung von Sprachbildern der Therapeuten zur Therapiebeendigung wird abschließend ein Konzept von Therapiebeendigung als Übergangsphase entwickelt. In dieses Konzept sind die vielfältigen Aspekte der Therapiebeendigung wie z. B. Zwischenzeit, Verlust, Wachstum, Prüfung und Aufbruch integrierbar. Mit einer Sicht von Therapiebeendigung als Übergangsphase wird eine differenzierte Bearbeitung diagnostischer und handlungsrelevanter Aspekte der Abschlussphase für Praxis und Forschung möglich.
