SSR marker based DNA fingerprinting of Tunisian olive (Olea europaea L.) varieties
No full textThis study aimed to test the efficiency of SSR markers to identify and to differentiate a set of 26 Tunisian olive varieties maintained at four collections. SSR analysis from 10 primer pairs revealed a total of 86 polymorphic alleles with 4 to 14 alleles per locus that allowed unique genotyping of the examined varieties. The Polymorphism Information Content (PIC) values ranged from 0.548 to 0.796 (average 0.719). The efficiency was found very high with average discriminating power overall 10 loci higher than 0.9. A combination of three SSR markers (ssrOeUA-DCA9, ssrOeUA-DCA13 and ssrOeUA-DCA16) was proposed for rapid identification of analysed cultivars. Three cultivars (Gerboui, Ain Jarbouaa and Regregui) thought to be identical resulted in absolutely different SSR profiles. This research showed that SSR is a suitable and effective tool to characterise olive varieties in Tunisian germplasm collections. The outcome of this study could be useful for varietal survey and the construction of a database of all olive varieties in Tunisia
El extranjero: Albert Camus vs. Kamel Daoud. Por un postexistencialismo libertario
No full textThe Stranger by Camus is one of the most widely read books in the world. This essay tackles Camus philosophy of the absurd in his philosophical tale, along with libertarian spirit that Daoud’s counter inquiry tends to defend, nearly half a century later, in The Meursault Investigation. Indeed the Algerian author offers a retelling of The Stranger in order to confront the absurd figured by Camus with those real harsh conditions of living that his own people had to endure, at least concerning its minorities. We are the absurd! This is the thesis the author wishes to defend. This dialogue between Daoud and Camus argues the issue of a potential process of independence and liberty from a libertarian and post-existentialist perspective.El extranjero de Albert Camus es uno de los libros más leídos del mundo. El presente ensayo pone en relieve la filosofía del absurdo que aborda Camus en este cuento filosófico con la visión libertaria defendida, medio siglo después, por Kamel Daoud en su contra encuesta: Meursault, caso revisado. El autor argelino propone reescribir El extranjero para confrontar el absurdo desde las condiciones objetivas de existencia sufridas por las minorías de su pueblo. ¡El absurdo somos nosotros!, es la tesis que defiende el autor. Este diálogo Albert Camus vs. Kamel Daoud argumenta la posible construcción de un proceso de independencia y de libertad a partir de un post-existencialismo-libertario

Does micronutrient supplementation improve outcomes in adult gastrointestinal surgery patients? A systematic review
No full textIntroduction: gastrointestinal surgery can result in short-term (in hospital) complications such as infections, post-operative ileus and poor wound healing and longer-term (post-discharge) complications such as intestinal failure, malnutrition and loss of bone mass. These complications can severely impact the patient and increase healthcare costs. Impaired immunity, excessive inflammation and oxidative stress can contribute to postoperative complications and poor outcome. Many micronutrients support immunity and help to control inflammation and oxidative stress. Therefore, providing micronutrients could mitigate poor outcome from surgery. The aim of this systematic review was to collate findings from randomized controlled trials (RCTs) of micronutrients provided to adult patients undergoing, or who had undergone, gastrointestinal surgery.Methods: searches were conducted in Medline and CINHAL; only literature from 2014 onwards was searched.Results: a total of 12 articles reporting data from 11 RCTs were included. These trials studied vitamin D alone (administered orally) or combinations of different micronutrients (administered orally, intravenously or in wound dressings). Six trials started the intervention following discharge from hospital. Six trials had a low risk of bias overall, while five had some concerns. Two trials found that vitamin D decreased the loss of bone density in those who had undergone bariatric surgery, but two other trials did not find this; vitamin D dose may be important in determining its effect. One trial found that vitamin D improved quality of life in those who had surgery and another found that vitamin D improved survival time and prevented relapse in some patients who had surgery for gastrointestinal cancer. Another trial found that vitamin D helped support the immune response following surgery; this could lead to fewer infections, although that outcome was not reported. Intravenous multivitamins shortened hospital stay and decreased oxidative stress in the immediate postoperative period in one trial. Using vitamin E and silicone in wound dressings decreased surgical site infection, postoperative pain, inflammation and hospital stay in one trial.Discussion: although some micronutrients may reduce risk of short- and long-term complications of surgery, insufficient trials have been conducted to make strong conclusions. Further research, especially with interventions in the perioperative period and looking at in-hospital outcomes, is needed

Contemporary African Literatures Under Tension : A “Tokenized” Werstern Gaze ? The Case of Algerian Writer Kamel Daoud
No full textKamel Daoud has become a globalized author. His authorial figure, increasingly polarized between his homeland and his host space, makes him a controversial writer. Indeed, the Algerian writer is often criticized for adopting a discourse in line with the host literary field, in this case France, thus adapting an authorial stance adjusted to the ideas and ideals of the coveted literary space. In turn, the host field offers the Algerian writer the media coverage necessary for his literary and social recognition, which is often criticized for being conditioned by symbolic expectations. His posture, which oscillates between criticism of his own country and a discourse adapted to the French intellectual space, raises the question of his possible tokenization. In this article, we propose to analyze the mechanisms of the literary and social recognition of the writer Kamel Daoud from the tokenist prism, through his discourses within his work and outside of itKamel Daoud est devenu un écrivain algérien et africain globalisé. Sa figure d’auteur, de plus en plus polarisée entre l’espace d’origine et l’espace d’accueil, fait de lui un écrivain controversé. En effet, il est souvent reproché au romancier algérien d’adopter un discours en adéquation avec le champ littéraire d’accueil, en l’occurrence la France, adaptant dès lors une posture auctoriale ajustée aux idées et idéaux de l’espace littéraire occidental. À son tour, le champ d’accueil offre à l’écrivain algérien la médiatisation nécessaire à sa reconnaissance littéraire et sociale, à laquelle on reproche souvent d’être conditionnée à des attentes symboliques. Sa posture, qui oscille entre la critique de sa propre contrée et un discours adapté à l’espace intellectuel français, soulève la question de sa possible « tokénisation ». Dans cet article, nous proposons d’analyser les mécanismes de la reconnaissance littéraire et sociale de l’écrivain Kamel Daoud sous le prisme tokéniste à travers ses discours dans son œuvre et à l’extérieur de cette dernière
Multiphase Modular Multilevel Converter Based Drive System for Oil and Gas Recovery in Subsea Applications
No full textAdjustable Speed Drives (ASDs) in subsea/offshore oil and gas applications are involved in several processes throughout production, transportation, and treatment phases, as they supply pumps and compressors. Therefore, ASDs’ in subsea applications have gone through continuous development. The currently existing systems exhibit several energy-conversion challenges that negatively impact the industry costs and green energy. In order to improve the energy-conversion efficiencies, this thesis, apparently, adopts a trend of using low-rating semiconductor devices to handle medium-/high-voltage levels along the various drive system stages. A trend that is believed, by the author, to become in the near future the foundation of flexible, redundant, and compact energy-conversion in the majority of medium-/high-voltage power applications. This thesis proposes the employment of Modular Multilevel Converters (MMCs) in MV-ASD applications in order to ease a transformerless operation while handling medium voltages using low-rating semiconductors. This, in return, reduces the system size and weight. The zero-/low-speed operation of MMC-based ASDs (a main challenge of applying MMCs in ASDs) is investigated in this thesis. The recent techniques proposed to improve operation during those intervals, implement complex hardware/software approaches. To cope with this issue, this thesis proposes multiphase machines for MMC-based AC-drives. Among several advantages regarding the power splitting, multiphase machines provide additional degrees of freedom compared to their three-phase counterparts. Novel exploitation to these additional degrees of freedom is proposed by injecting a secondary current component in the load current with specific magnitude and frequency during zero-/low-speed intervals enabling the drive system to function duly. Since the control of these secondary components is already inherited in the current controller structure of any multiphase machine, no additional algorithms or sensors will be required. Moreover, a hybrid-boost MMC converter is proposed to boost the MMC output voltage. The stepped output voltage generated by the MMC reduces or eliminates the filtering requirements. The boosting capability of the proposed architecture eliminates the need for bulky low-frequency transformers at the converter output terminals. In order to enhance the drive output torque, a Trapezoidal Phase Disposition Pulse Width Modulation Technique (TPD-PWM) is proposed in this thesis. Different slope angles of the trapezoidal modulation signal are tested and compared to other modulation techniques in order to select the angle with the best torque enhancement meanwhile maintaining good Total Harmonic Distortion (THD) levels. Moreover, the adopted modulation technique reduces the switching losses compared to the conventional Sinusoidal-based PWM. Eventually, a series-connected Half-Bridge (HB) modules are proposed as an Active Front End (AFE) rectifier for the drive system in order to generate an adequate DC-link voltage for the medium-voltage drive system using low-rating semiconductor devices. The proposed techniques through this thesis have been supported with both experimental and simulation results
