Cells must sense changes in their environment and respond appropriately in order to survive. A common survival strategy is for cells to translate an environmental signal into the activity of a transcription factor they effects a change in gene expression. In this way, cells can express a gene just-in-time for its biological function. In addition, cells can coordinate the activity of many transcription factors to construct genetic regulatory networks that integrate many inputs to control complex cellular behaviors. In this thesis, I use the model system Caulobacter crescentus to examine the regulation of CtrA, the essential transcription factor at the core of the Caulobacter cell cycle regulatory network. CtrA regulates the activity of approximately 100 cell cycle genes many of which are critical for cell cycle progression. CtrA activity is regulated at the level of abundance, post-transcriptional modification, and here I show that CtrA is also regulated by a novel protein-protein interaction. I identify SciP, a GI specific inhibitor of CtrA transcriptional activity and show that SciP forms a complex with CtrA at CtrA dependent promoters. The SciP/CtrA interaction likely prevents CtrA from recruiting RNA polymerase thereby blocking the activation of transcription. In addition, I show that SciP is restricted to G1 by regulated proteolysis. I identify the Lon as the SciP protease and show that Lon is required for SciP proteolysis in vivo and that E. coli Lon degrades SciP in vitro. Finally I engineer a stable allele of sciP and show SciP proteolysis is critical for proper cell cycle progression.

Full textReconstructive Surgery techniques seek to achieve two main objectives, repair body defects in the most appropriate way and minimize the donor area lesion. The microsurgical techniques allowed the development and popularization of the free flaps, enabling reconstructions in areas where previously was not possible. The imaging techniques evolution allowed greater sensitivity and specificity in the identification and selection of the perforating vessels that feed the flaps. The most useful imaging test in this identification is multidetector computed tomography (MDCT). Two of the most complex body areas for reconstruction are the distal portion of the limbs and head and neck. They have a thin skin, with thin adipose paniculus and the lesions in those places require very complex three-dimensional reconstructions. The search for a thin, broad, malleable flap with a constant vascular anatomy and minimal donor site lesion led to the development of the SCIP perforator flap. The inguinal area is a ideal flap donor site that provides the above characteristics. The free classic inguinal flap was described in 1973 (Mc Gregor) with vascular base in the deep branch of the superficial iliac circumflex artery (SCIA). This flap did not undergo any significant changes since its description in 1973 to 2004 (Koshima). This year was designed to be a perforator flap, with a vascular base in the perforators of this deep branch (indirect perforator type D or F of Nakajima). This indirect SCIP perforator flap presents drawbacks that have prevented its popularization such as: short pedicle, medium size and the need for supramicrosurgery techniques. This doctoral thesis aims to clarify the vascular base of the SCIP flap, establish a pre-surgical planning using non-invasive imaging techniques (MDCT) that allow a safe elevation of the flap and a design that provides the maximum benefits minimizing its drawbacks. The anatomical constancy of the superficial branch of the SCIA (direct cutaneous perforator C type of Nakajima) is considered. The use of this branch as a vascular base, of this variant of the SCIP flap, defining it as a direct flap. The location of this superficial branch is proximal and medial to the anterosuperior iliac spine (EIAS), thus providing advantages with respect to the indirect SCIP flap: avoid the use of supramicrosurgery techniques, larger cutaneous island size could be raise, longer vascular pedicle length and direct closure of donor site. All the patients in the study had a positive identification in the MDCT of the superficial branch of the SCIA. A probability of 90% of exit point of this branch, to suprafascial plane, in an area determined by values of X of +-125mm to +-77mm and of values of Y of -130mm to -63mm with respect to the umbilicus is establishes. Converting these data to reference points located on both EIAS facilitate clinical application, we obtain a 90% probability of finding the exit point of this branch in a circumference whose center is medial and distal to both EIAS in values for X of 17mm and for Y of 18mm, and whose radius is 21mm. The clinical application of the direct SCIP flap is detailed in five cases of reconstruction on the distal extremity and head and neck. Therefore, the direct SCIP flap has a constant vascular axis constituted by the superficial branch of the SCIA, giving a medium or large flap with fine and moldable skin and direct donor site closure possibility. This flap being ideal in the reconstruction of tissue defects in areas such as leg, foot, forearm, hand, head and neck.

Full textDetermina el déficit cognitivo con la escala Screen for Cognitive Impairment in Psiquiatry (SCIP) en pacientes diagnosticados con primer episodio de Esquizofrenia en el Hospital Nacional Víctor Larco Herrera durante el periodo 2011 - 2012. El estudio es observacional analítico. La población fueron pacientes que se atendieron en los servicios de consultorios de psiquiatría que acuden al Hospital Nacional Víctor Larco Herrera durante el periodo 2011-2012, la muestra estuvo dividida en dos grupos: el grupo caso conformado por 20 pacientes con diagnóstico de primer episodio de esquizofrenia y el grupo control: 30 personas sanas. Se aplicó la escala Breve SCIP para determinar el déficit cognitivo de los pacientes. Se estimaron las frecuencias absolutas y relativas de las variables cualitativas y medidas de tendencia central y de dispersión de las cuantitativas. Se utilizó para el análisis bivariado la prueba Chi cuadrado para las variables cualitativas y t-student para las variables cuantitativas. Toda interpretación estadística se realizó con un nivel de significancia del 95%. La edad promedio de los pacientes con esquizofrenia fue de 22.5 ± 1.9 mientras que la edad promedio en el grupo control de personas sanas fue de 23.8 ± 3.8. El grupo caso de pacientes con esquizofrenia estaba compuesto por el 55 % varones y 45% mujeres, mientras que el grupo control tanto la población de sexo masculino y femenino fue de 50%. El nivel educativo superior en el grupo de pacientes con esquizofrenia fue de 45% y en el grupo de personas sanas de 66.3%. El promedio del tiempo de enfermedad en los pacientes con primer episodio de esquizofrenia fue 7.9± 1.4 meses y el 85% de estos pacientes recibieron soporte familiar. En la primera evaluación, el 85% de los pacientes con primer episodio de esquizofrenia presentaron déficit cognitivo mientras que en el grupo de personas sanas el déficit cognitivo fue de 6.7% (p<0.001). La segunda y tercera evaluación se realizaron con periodo de intervalo de 2 semanas entre cada una de ellas. En la segunda evaluación, el 100% de los pacientes con esquizofrenia presentaron déficit cognitivo mientras que en el grupo de personas sanas no se obtuvo ningún caso de déficit cognitivo.nLa tercera y última evaluación, se realizó sólo en el grupo de pacientes con esquizofrenia, se obtuvo como resultado el 100% de pacientes con déficit cognitivo. El puntaje promedio de los sub test en la primera y segunda evaluación en los pacientes con primer episodio de esquizofrenia es menor comparado con el puntaje promedio del grupo control de personas sanas (p<0.001), es decir, el puntaje promedio en el test de aprendizaje verbal inmediato, el test de memoria de trabajo, el test de fluidez verbal, el test para aprendizaje diferido y el test de velocidad de procesamiento de pacientes con esquizofrenia de primer episodio es menor que el puntaje promedio en el grupo de personas sanas. La tercera evaluación se realizó en el grupo de pacientes con primer episodio de esquizofrenia obteniéndose los promedios en el test de aprendizaje verbal inmediato fue 15.7±1.8, en el test de repetición de consonantes fue 13.5±1.6, en el test de fluidez verbal fue 13±1.7, en el aprendizaje diferido fue 5.6±0.8 y en el seguimiento visomotor 10.8±3.0. Se concluye que, en la primera evaluación, el 85% de pacientes con primer episodio de esquizofrenia en el Hospital Víctor Larco Herrera presentó déficit cognitivo, durante el periodo 2011 a 2012. En las siguientes evaluaciones, a la segunda y cuarta semana, el déficit cognitivo fue de 100%. El puntaje promedio de los tests de aprendizaje verbal inmediato, de memoria de trabajo, de fluidez verbal, de aprendizaje diferido y de velocidad de procesamiento en pacientes con primer episodio de esquizofrenia es menor comparado con el puntaje promedio del grupo de personas sanas (p<0.001).

Full textTo do so, the company must consider customers' reactions to these prices, as they may refuse to buy a given product or service if its price is too high. This is commonly known in literature as a pricing problem.
This class of problems, which is typically bilevel, was first studied in the 1990s and is NP-hard, although polynomial algorithms do exist for some particular cases. Many questions are still open on this subject.
The aim of this thesis is to investigate mathematical properties of pricing problems, in order to find structural properties, formulations and solution methods that are as efficient as possible. In particular, we focus our attention on pricing problems over a network. In this framework, an authority owns a subset of arcs and imposes tolls on them, in an attempt to maximise his/her revenue, while users travel on the network, seeking for their minimum cost path.
First, we provide a detailed review of the state of the art on bilevel pricing problems.
Then, we consider a particular case where the authority is using an unit toll scheme on his/her subset of arcs, imposing either the same toll on all of them, or a toll proportional to a given parameter particular to each arc (for instance a per kilometre toll). We show that if tolls are all equal then the complexity of the problem is polynomial, whereas in case of proportional tolls it is pseudo-polynomial.
We then address a robust approach taking into account uncertainty on parameters. We solve some polynomial cases of the pricing problem where uncertainty is considered using an interval representation.
Finally, we focus on another particular case where toll arcs are connected such that they constitute a path, as occurs on highways. We develop a Dantzig-Wolfe reformulation and present a Branch-and-Cut-and-Price algorithm to solve it. Several improvements are proposed, both for the column generation algorithm used to solve the linear relaxation and for the branching part used to find integer solutions. Numerical results are also presented to highlight the efficiency of the proposed strategies. This problem is proved to be APX-hard and a theoretical comparison between our model and another one from the literature is carried out.

Full textThe emergence of real-time applications, like Voice over IP and video conferencing, in IP networks implies a challenge to the underlying infrastructure. Several real-time applications have requirements on timeliness as well as on reliability and are accompanied by signaling applications to set up, tear down and control the media sessions. Since neither of the traditional transport protocols responsible for end-to-end transfer of messages was found suitable for signaling traffic, the Stream Control Transmission Protocol (SCTP) was standardized. The focus for the protocol was initially on telephony signaling applications, but it was later widened to serve as a general purpose transport protocol. One major new feature to enhance robustness in SCTP is multihoming, which enables for more than one path within the same association.
In this thesis we evaluate some of the mechanisms affecting transmission performance in case of a switchover between paths in a multihomed SCTP session. The major part of the evaluation concerns a failure situation, where the current path is broken. In case of failure, the endpoint does not get an explicit notification, but has to react upon missing acknowledgements. The challenge is to distinguish path failure from temporary congestion to decide when to switch to an alternate path. A too fast switchover may be spurious, which could reduce transmission performance, while a too late switchover also results in reduced transmission performance. This implies a tradeoff which involves several protocol as well as network parameters and we elaborate among these to give a coherent view of the parameters and their interaction. Further, we present a recommendation on how to tune the parameters to meet telephony signaling requirements, still without violating fairness to other traffic.
We also consider another angle of switchover performance, the startup on the alternate path. Since the available capacity is usually unknown to the sender, the transmission on a new path is started at a low rate and then increased as acknowledgements of successful transmissions return. In case of switchover in the middle of a media session the startup phase after a switchover could cause problems to the application. In multihomed SCTP the availability of the alternate path makes it feasible for the end-host to estimate the available capacity on the alternate path prior to the switchover. Thus, it would be possible to implement a more efficient startup scheme. In this thesis we combine different switchover scenarios with relevant traffic. For these combinations, we analytically evaluate and quantify the potential performance gain from utilizing an ideal startup mechanism as compared to the traditional startup procedure.

Nas pilhas de protocolos de rede típicas, como TCP/IP, a camada de rede oferece transmissão não confiável de datagramas um serviço muito primitivo para ser usado diretamente pelas aplicações em geral. É a camada de transporte a responsável por oferecer serviços de rede confiáveis e confortáveis às aplicações. A pilha TCP/IP oferece tradicionalmente apenas dois protocolos de transporte: TCP e UDP. O UDP implementa apenas o recurso de portas, sem acrescentar confiabilidade à rede. O TCP, por outro lado, oferece um serviço confiável, com conexões ponto-a-ponto e transmissão de bytes, abstraindo completamente as características da rede. TCP e UDP são dois extremos; algumas aplicações desejariam usar ao mesmo tempo recursos de ambos os protocolos, e/ou ter controle mais direto sobre alguns aspectos da rede. Tal necessidade surgiu na sinalização telefônica, o que motivou a criação de um novo transporte, o SCTP. O SCTP (Stream Control Transmission Protocol) guarda diversas semelhanças com o TCP, mas também apresenta diversos recursos adicionais interessantes: transmissão de mensagens indivisíveis, multiplos fluxos de mensagens por conexão, variação da confiabilidade das mensagens, bem como melhorias de segurança. A proposta deste trabalho é apresentar os recursos do SCTP, estudar a aplicabilidade do mesmo a protocolos de aplicação que hoje utilizam TCP ou UDP como transporte, e realizar testes de desempenho sobre uma implementação real do SCTP, com a simulação de diversas condições típicas de rede. O desenvolvimento do trabalho envolveu uma razoável revisão bibliográfica sobre protocolos em todas as camadas, criação e adaptação de aplicativos para execução dos testes, uso de ferramentas de simulação de rede, escolha de métricas de avaliação de desempenho, e adaptação de protocolos de aplicação ao SCTP.

Full textThe effectiveness of Urophora cardui L. as a biological control agent is limited due to a lack of synchrony between the agent and the weed. This can be improved through integration with herbicides or mowing in time or space. Other biological control agents such as Orellia ruficauda Fab., Cassida rubiginosa Muell., and Puccinia punctiformis (Str.) Rhol. resulted in limited suppression of the weed population. Mowing was not effective in sustaining weed reductions for longer than one year. Application of clopyralid or 2,4-D/dicamba effectively reduced the weed population. The application of 3.37 kg a.i. ha$ sp{-1}$ 2,4-D/dicamba or 0.3 kg a.i. ha$ sp{-1}$ clopyralid with the spring and summer mowings were the most effective mowing/herbicide combinations over the two-year period.

Full textThis work deals with the comparison between the OFDM (orthogonal frequency division multiplexing) and SCCP (single carrier with cyclic prefix). These systems are analyzed as a function of the modulation order, the sensitiveness to the channel coding rate and to the interleaver configuration. The comparison is accomplished by means of a system model that leads to an universal framework to both analyzed systems. Theoretical results are obtained exploring convexity properties of functions. In addition, some results provided by Monte Carlo simulation are also presented to complement the analysis. The systems are compared mainly in terms of the BER (bit-error rate). Moreover, comparisons in terms of outage probability obtained by cutoff rate and in terms of the effective SNR (signal to noise ratio) at the equalizer output are also provided. Finally, the systems will be compared when channel estimation error are presented at the receiver.

Nas redes de dados das operadoras de telefonia celular é fundamental que o protocolo utilizado na comunicação entre terminais seja confiável e seguro e que possa prover o máximo de garantias a integridade dos dados. Os protocolos usualmente utilizados na comunidade científica fazem parte da pilha TCP/IP. O protocolo UDP não acrescenta confiabilidade à rede e apenas implementa a multiplexação. Por outro lado, o protocolo TCP tem a vantagem de ser um protocolo confiável possuindo conexões ponto-a-ponto. Na rede de telefonia celular, considera-se nas maioria das vezes o protocolo TCP e deseja-se que as vantagens de UDP existam no TCP. Desta forma, nessa dissertação optou-se pelo estudo dos protocolos SCTP e XTP por possuírem tais características em comum e acrescentar alguns diferenciais. Entre os recursos que mais de destacam no SCTP estão a transmissão de mensagens indivisíveis, múltiplos fluxos de mensagens por conexão, variação da confiabilidade das mensagens, entre outras. Por outro lado o XTP tem como características trabalhar em aplicações de alto desempenho, e por possuir similaridades com o TCP. A proposta deste trabalho de pesquisa é de prover um estudo empírico utilizando-se dos protocolos TCP, SCTP e XTP. O estudo caracteriza-se por considerar os recursos do SCTP e XTP, a fim de demonstrar em uma rede real interna de uma operadora de telefonia móvel o diferencial dos mesmos suportando protocolos de aplicação e simulando diversas condições de rede.

Full textPerformance measurements have become very important tools for companies because of ever increasing global competition in today’s market. Delivery dependability is one of the three most important performance measurements for companies to focus on and that makes this analysis, of the dependability, both very interesting and up to contemporary. In this rapport different aspects of delivery dependability will be dealt with, and a weight will be on what to measure and how to measure it together with how to present the outcome of the measurements. A discussion has also been held regarding what goal the company should have on its dependability. The aspects that have been handled in this paper are based on the fact that Sanmina-SCI experiences its dependability measurement as a time costing task and at the same time it is important to understand the meaning of the result. To get the answer to our questions a theory study was made to get an understanding on needs to be measured and how to measure it. A thorough examination on the present situation at Sanmina-SCI was necessary to get the information on what problems the company is faced with and with these facts a result was made. The examination of the company was made with interviews together with our own observations and assessments of today’s measures and reports.
The result from the examinations shows that the measurements that are made manually at Sanmina-SCI can be made automatically instead. The preparation will then be at a minimum. At the same time as common report for the presentation of the delivery dependability has been created to make the reporting to the headquarter easier for all departments. The layout on the common report, that will be created with a macro, is well thought through and some parts of the report are totally new for Sanmina-SCI for example delivery dependability by product line. It has come to light that it’s very important that all employees that are in contact with the dependability result understand what it shows. Based on that fact the common report was made with an explanation added. A significant conclusion that has been drawn is that the result for the deliveries, that is measured against, what has been promised and what has been requested from the customer, not can be compared because of the differences in input. From this conclusions a proposal on a new way of measure has been created. The result of the analysis of Sanmina-SCIs goals of dependability shows that they are on a very high level but the company has not fully analysed the meaning of high goals compared to costs.
An analysis of measurements is something that is valuable for all companies and organisations, which makes this report relevant to read independent in which industries the company or organisation are in. A performance measurement are technical very easy to measure but in practice it’s much harder. Problem with performance, definition of data, analysis and reporting is common.

Full textThis doctoral research aims to study the relationship between Governance, Human Resource Management and Strategy of SCOP. These co-operative enterprises have an original and innovative political project and are beneficiaries of a triple linage of economic, political & social nature. Their values which derived from the nineteenth century are of solidarity, collective inter-generational ownership and equity.The identification of risks of tension and disintegration inherent to such an hybrid form of governance calls for a adequate management to run a co-operative organisation where worker members have a majority vote in co-responsibility.This issue emerging from both the field and the literature is studied in an innovative triptych approach based on a qualitative methodology. The analysis of practices and speeches - gathered from managers of 16 micro co-operatives and small & medium co-operatives of Rhône Alpes and from leaders of the co-operative sector – has revealed, on one hand, brakes and levers and on the other hand, contingency elements to a sustainable co-operative development of SCOP.These results have allowed the development of an ideal type of co-operative management and sustainable co-operative development based on co-operative management tools designed to prevent the risk of individual and collective tensions and to strenghthen the link between co-operative governance, co-operative management and co-operative development

Full textMobilnätsoperatörer använder sig av IP Packet exchange (IPX) tjänstetillhandahållare för att koppla ihop sina nät med andra operatörers nät. Mobilnätsoperatörer kan fritt välja en IPX tjänstetillhandahållare för sin datatrafik och en annan för sin kontrolltrafik. Denna uppsats undersöker fallet för kontrolltrafik, specifikt Stream Control Transmission Protocol (SCTP) kommunikationsprotokoll för Diameter protocol-trafik vid användares roaming från sitt Long Term Evolution (LTE)-hemmanät till en annan operatörs LTE-nät. Examensarbetet avser etablera en uppsättning av SCTP-parameterkonfigurationer som ger förbättrad applikations-/tjänstetillgänglighetsnivå mellan två Diameter-noder i olika nätmiljöer, särskilt för IPX tjänstetillhandahållare som är Diameter tjänstetillhandahållare. Dessa tjänstetillhandahållare erbjuder Diameter-konnektivitet till sina kunder, som är mobilnätsoperatörer. Dessa mobilnätsoperatörer tillhandahåller i sin tur LTE-roamingtjänster till sina kunder. Tyvärr är det olämpligt att tillämpa de enhetliga konfigurationsrekommendationer, som ges i SCTP- och Diameter-protokollens dokumentation, i olika nätmiljöer. Samtidigt ökar Diameter-signaleringstrafiken mycket snabbt. Därför är det värdefullt att identifiera lämpliga parameterkriterier för Diameter-tjänstetillhandahållare att säkerställa 100% tillförlitlig Diameter-tillgänglighet för sina kunder. I detta examensarbete har författaren undersökt hur trimning av SCTP-parametervärden påverkar Diameter-meddelandeöverföring vad avser överföringstiden tur- och retur, och identifierat de avgörande parametrarna för återställande av paketförluster. Både IPX tjänstetillhandahållare och mobilnätsoperatörer kan använda dessa värden som referens för att åstadkomma hög tillgänglighet för Diameter-överföring vid tillförlitliga, halvtillförlitliga och otillförlitliga nättransportförutsättningar.

Resumo: As células NK secretam as citoquinas INF-gama e TNF-alfa ¿ moléculas associadas com a resposta imune mediada por células do tipo Th1 ¿ em resposta a infecção por Plasmodium e ainda respondem à indução pela IL-12, conseguindo enfim, diminuir a mortalidade por P. chabaudi. Apesar de estudos comprovarem que as células NK e suas citoquinas têm papel importante no controle imunológico da malária, sabe-se que fatores genéticos representam um dos maiores determinantes de resistência do hospedeiro para infecção da malária. Para testar o papel das células NK na resposta imune contra malária, foram adotados dois modelos animais: a linhagem C.B-17 SCID/SCID, devido à ausência de células T e B, e camundongos C57BL/6 KO para interferon gama , que apresentam o gene para interferon gama bloqueado. Nesse trabalho, a capacidade dos animais SCID e KO para interferon gama controlarem a infecção foi avaliada comparando-se a parasitemia entre eles; Foram adotadas , como controle, as linhagens imunocompetentes BALB/c/Uni e C57BL/6/Uni. Esses animais foram infectados intraperitonealmente com 106 eritrócitos parasitados com P. chabaudi da linhagem CR e tiveram sua parasitemia medida em intervalos pré-determinados por várias semanas. Tanto os animais SCID quanto os animais KO, mantiveram altos picos de parasitemia, mesmo durante a fase crônica da infecção. Os camundongos imunocompetentes controlaram a infecção. Os resultados indicam que as células NK colaboram no controle da infecção, diminuindo a parasitemia, porém a imunidade ao P. chabaudi não depende somente da produção de interferon gama, podendo estar relacionada também a fatores genéticos. A malária compromete o rim, não só pela deposição de imunocomplexos, pois os mundongos C.B17 SCID/SCID/Uni desprovidos de imunoglobulinas também desenvolveram patologias renais: descamação das células tubulares, trombose e necrose glomerular, observadas também em camundongos C57BL/6 KO. As alterações renais em C57BL/6 foram mínimas, possivelmente em função do genótipo resistente desta linhagem
Abstract: The NK cells secrete the citoquinas INF-gamma and TNF-alpha - molecules associated with the immune protective mediated by cells of the type Th1 - in response to infection for Plasmodium. Instead the induction of these cells with IL- 12 helps to reduce the mortality by P. chabaudi. Although studies was related the NK cells and its citoquinas play a important role in the control of the malaria, it is known that the genetic factors represent one of the largest determinant of resistance by host infected by Plasmodium sp. For testing the malaria immunity by NK cells, we have used two animal models: the C.B-17 SCID/SCID because their absence of T and B cells and the C57BL/6 animals which are deprived for interferon-gamma gene. In this research, the capacity of both to control the infection was evaluated comparing the parasitaemia among them, using the immunocompetent BALB/c/Uni like a control animal. They were infected intraperitoneally with a dose of 106 parasited red blood cells and the parasitaemia was determined in established intervals for several weeks. So the animals SCID as the animals KO have maintained high parasitemia during chronic phase of the infection. The immunocompetents mice have decreased the parasitemia level , controlling the infection. It could be concluded that the NK cells collaborate to the malaria immunity reducing the parasitaemia; however the data indicating they don't act alone and the resistance against the P. chabaudi could be also a genetic factor. The malaria affects the kidney, not only for the immunocomplex deposition, because the mice C.B17 SCID/SCID/Uni unprovided immunoglobulins also developed renal pathologies: tubular cells exfoliation, thrombosis and necrosis in the glomerulus, also observed in C57BL/6 KO Interferon-gamma animals. It was not observed kidney alterations in C57BL/6 probably because resistant genotype
