In Vivo Immunomodulatory Potential of Partial Purified Lectin from the Saffron Milk Cap Mushroom, Lactarius deliciosus (Agaricomycetes), against Colloidal Carbon Particles
No full textMushrooms compounds and biomolecules are known for their biological beneficial effect and dietary properties. Theirs molecules are using at immunology for the ability to stimulate immune cells and biotherapy of diseases. In this study, the immunomodulatory effect using carbon clearance test in vivo of partial purified lectins of Lactarius deliciosus using DEAE-Sephacyl column, with sugar affinity against galactose, methyl-B.D galactopyranoside and lactose, specify showed a significant effect on phagocytic activity and half time of life of carbon particles in mice with different concentrations (5, 10, 15 and 30mg/kg). The results showed that: the immunomodulatory effect increased in low doses and decreased after in high doses as compared with the control group p< 0.0001. L. deliciosus lectin exerted a dose-dependent immunostimulant activity at the reticulo-endothelial system, phagocytic activity on macrophages and neutrophils in spleen and liver against the carbon colloidal
From the river to the sea? : honour, identity and politics in historical and contemporary Palestinian rejectionism
No full textThe present thesis seeks to understand and explain the rhetoric and
behaviour of the rejectionist 'current' within the Palestinian national
movement. It proceeds from the view that extant scholarship, primarily from
within the fields of terrorism and security studies, has profoundly
misunderstood rejectionist speech and behaviour by ignoring the
explanatory capacity of Emic - the research subject's perception - as well as
the influence of the sociocultural milieu within which rejectionism exists.
The thesis proceeds to set up a 'socioculturally sensitive' analytical
framework drawn from social identity theory, a heuristic, non-reductionist
model for understanding group interaction and conflict. Emphasizing
cultural norms and cues identified by anthropologists as salient in the
eastern Mediterranean, the thesis suggests that the social value of honour,
patron-client dynamics and a firmly entrenched group orientation must be
significant elements of a model for understanding rejectionist behaviour.
The main analytical narrative suggests that for reasons derived from
ideology, patron-client relations and group dynamics, what has distinguished
the rejectionists from the mainstream have been a qualitatively different set
of preconditions for, and objectives of diplomatic negotiations. To the main
rejectionist factions the goal of liberating Palestine has always been
inextricably intertwined with the goal of restoring national honour; one
without the other has been impossible and to claim otherwise would mean a
depletion of factional and personal honour. To the rejectionists, there has
never been any question of deviating from the fundamental goals - national
recognition, repatriation, self-determination and independent statehood, not
even for tactical reasons. This 'higher standard' likely derives from their
structurally and politically subordinate position within the national
movement, and the need to creatively enhance their own social status and
appeal

Bi-directional Solid Oxide Cells used as SOFC for Aircraft APU system and as SOEC to produce fuel at the airport
No full textLeaders of European union and G8 have set the target of 80% reduction in greenhouse gases emissions by 2050 by decarbonizing the power and transport sector. There are several pathways to achieve this, some of them being a) use of renewable power and biomass b) improvement in transport and building energy efficiency and c) replacement of fossil based fuel with sustainable fuel. This thesis is focussed on some of the measures which can be taken by Air Transportation Industry to reduce GHG emissions and carbon footprint. Although, there are many ways in which air transport industry can achieve this goal, this work mainly discusses a) increase in power generation efficiency of aircraft systems b) use of sustainable fuels for aircrafts and c) some ways for sustainable fuel production for aircrafts in an efficient and economic way. However, it is only starting point for discussion and can be further extended to include more efficient and cheaper technologies with reduced carbon foot-print. In this study, use of bi-directional Solid-Oxide Cells (SOC) as auxiliary power unit (APU) on-board commercial aircraft is explored. These bi-directional SOC APU units can be used in the airport energy network either to produce cleaner energy or to produce sustainable fuels depending on the energy demand. This work focusses on use of these bi-directional SOCs as fuel cells during flight operations and as electrolysers to produce sustainable fuel at the airport when the aircrafts are parked. Hence, complete fuel production plant is designed to be situated at the airport. The scope of this thesis is limited to production of fuel for aircraft APU use only. Further extension of this project can include use of these bi-directional SOCs for providing electricity to the airport and fuel for other purposes. For analysis, medium range aircrafts like A320 and B737 are considered. This system is designed and dimensioned for producing 500KW of electric power on-board aircarft. Jet fuel and ammonia are considered as fuel options for Solid Oxide Fuel Cell-Gas Turbine (SOFC-GT) based APU. Small scale airports like Eindhoven are studied to understand the flight frequency and parking duration for the aircrafts. These bi-directional SOCs are operational as Solid Oxide Electrolyzer Cell (SOEC) only when the aircraft is parked. Co-electrolysis is performed to produce syngas and steam electrolysis is done to produce hydrogen at the airport. Jet fuel is synthesized from syngas through Fischer Tropsch process and ammonia is synthesized from H2 and N2 through Haber Bosch process. Fuel synthesis plants are also designed as part of stationary fuel production plant at the airport. The fact that electrolyzer operates on excess available renewable electricity only, needs a special mention here. Intermittent nature of excess renewable electricity requires implementation of another source of sustainable syngas for fuel production so that sufficient capacity to supply all demand is ensured and robustness against delivery risks is achieved. Biomass gasification is one other method for generating fossil-free fuel. It uses biomass (birch wood) to produce syngas for sustainable fuel production at the aiport alongwith electrolysers. This leads to three cases of fuel production: - Case-1: Gasifier+fuel synthesis - Case-2: SOEC+fuel synthesis - Case-3: Gasifier+SOEC+Fuel synthesis ASPEN PLUS is used for modelling SOFC and stationary fuel production plant models with both jet fuel and ammonia. Modelling procedure for all the models is explained in detail with input parameters and process conditions. Thermodynamic analysis is carried out to compare the exergy efficiency of jet fuel and ammonia based SOFC-GT systems. It is observed that both jet fuel and ammonia based SOFC-GT systems give 62% and 58% exergy efficiency respectively which is higher than the conventional APU systems. Similarly, section by section exergy analysis is carried out for jet fuel and ammonia production plants to understand the exergy destructing processes. Comparison is made between exergy efficiency of jet fuel and ammonia production plants at the airport to understand thermodynamic behavior of both. Jet fuel synthesis produces significant amount of hydrogen and gasoline alongwith jet fuel as product. Therefore, two scenarios are analysed for exergy comparisons. a) Ammonia and jet fuel considered as product: Ammonia shows higher exergy efficiency than jet fuel production for all three cases enumerated above. b) Ammonia and (jet fuel, gasoline, hydrogen) are considered as useful products: For case-1 and case-3, jet fuel plant is exergetically more favorable than ammonia plant. However, for case-2, ammonia plant has higher exergy efficiency than jet fuel plant.SPETProcess and EnergyMechanical, Maritime and Materials Engineerin
Le rôle du parler populaire dans la structuration du discours médiatique de la presse algérienne lors d’un événement sportif
No full textThe author finds in the coverage of the 2009 Egypt–Algeria soccer match a number of changes in the journalistic practices of the Algerian French-language press. Popular language was powerfully present on newspaper front pages. The author suggests that the Algerian French-language press coconstructed the soccer event to promote a kind of “Algerianness” in opposition to the Arabness “self-proclaimed” in the Cairo media. The analysis is based on 97 headlines from four Algerian newspapers—two sports papers and two general-interest ones—published between November 14 and 19, 2009. The study also draws on semistructured interviews of four newspaper managers, four editors, and eight journalists conducted between 2013 and 2020
Shah Abdul-Latif Bhitai and the Call to Gallows
No full textShah Abdul Latif Bhittai is one of the most revered saints and most loved poets of Sindh. His Shah jo Risalo has been translated into many languages from Sindhi and a large number of scholars, both Pakistani and foreign, have tried to understand and explain the philosophy and the message in Shah Latif`s poetry. The author has explained in this paper that the worldly love had led Shah Latif to eternal and real love, that is the love of God, and his worldly love is but a metaphor for the eternal and true love of Allah, a relationship between the soul of an individual and the Soul of the Cosmos. But the author laments that tyranny of the feudal system still exists in Sindh and Shah Latif`s call to gallows remains silent
Cellular Communications Using Aerial Platforms
No full textThis paper is devoted to the study of cellular communications using aerial platforms (APs). A set of key equations is derived that quantify the coverage area on the ground as a function of AP elevation, the operation of the adaptive multibeam antenna on the AP, and the formulation of contiguous terrestrial cells and their shapes. Specifically, we consider the deployment of an AP to provide terrestrial mobile radio communications using the universal mobile telecommunication system operating in its wide-band code-division multiple-access mode. Calculations are made of the number of users versus Eb/No for different service rates. Multi-tiered cellular structures having cells of different size that are steerable with the offered teletraffic are examined. The array structure to achieve this is identified. The preliminary results shows that an AP at a height of 21 km covers an area of radius 517 km. Up to 21 users per cell with a service rate of 8 kb/s can be accommodated in the 2.2-GHz band. These services can be provided within an area of radius 70 km with transmitted powers of less than 1 W. High system capacity is proved to be possible by constructing cells of radius as small as 100 m using square planar arrays with dimensions of less than 12 m x 12 m. The AP system provides high capacity and Doppler frequency shifts that only originate from roving mobiles
Microstructural Evolution in Additively Manufactured Fe-Cr-Ni Maraging Stainless Steel
No full textIn this work, the effect of heating rate on the phase transformation temperatures was investigated using dilatometry analysis. Continuous heating and isothermal holding above Ac3 temperature on microstructural evolutions in additively manufactured (AM) parts of Fe-Cr-Ni maraging stainless steel were studied. The microstructural features developed within the heating processes were characterized employing electron backscatter diffraction and transmission electron microscopy. Austenite reversion was found to take place in two steps for the AM parts by a diffusive mechanism as well as the precipitation reactions. Although grain refinement occurred during the austenite reversion of the continuously heated samples, the microstructure showed a coarser grain size after isothermal heating. The crystallographic orientations developed after the heating processes were different from those of the initial ones implying the absence of the austenite memory effect.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Kevin Ross
