Physical characteristic study of saw dust as liquid fuels application / Syed Ahmad Alhaddad Syed Osman
No full textNowadays major issues regarding the climate changes due to the emissions of greenhouse gases and increasing demand on usage of energy due the technological changes and population must be overcome. These issues brought the attentions of researchers on doing extensive study on the energy alternative which is ecofriendly and does not influenced on the global warming. Thus, this research study was focused on the characteristics of saw dust biomass as an alternative for liquid fuel application through analyzing of its physical properties; proximate, heating value, FourierTransform Infrared Spectroscopy (FTIR) and Thermogravimetric analysis (TGA). Biomass was good solutions for an alternative for energy production due to its low cost, energy saving and environmental friendly. This study shows the usage of saw dust biomass as an alternative for biofuel energy production towards the environment. The saw dust has high heating value of 3.0394 MJ/kg. Based from the proximate analysis, the saw dust has high volatile matter (60.47%), low fixed carbon content (21.71 %), low ash content (10.86 %) and low moisture content (6.96 %) which indicates it can be used as liquid fuel. On the other hand, FTIR analysis shows the result of the functional group obtain in the sample while TGA analysis produced the result on the mass loss achieved by saw dust sample during pyrolysis which is at 65.8% with high decomposition rate at 3.57 mg/min

Generation of 22-mJ, 2.0-ps Pulses from a 1-kHz Ho:YLF Regenerative Chirped Pulse Amplifier
No full textWe report a CW-pumped Ho:YLF regenerative amplifier (RA) delivering pulses with 22.5-mJ energy and 2.0-ps duration at 1 kHz. The RA emitting at 2051 nm is broadband-seeded and implemented in a chirped pulse amplification system. © 2024 The Author(s
Pure-rotational 1D-CARS spatiotemporal thermometry with a single regenerative amplifier system
No full textWe report spatiotemporal pure-rotational coherent anti-Stokes Raman spectroscopy (CARS) in a one-dimensional imaging arrangement obtained with a single ultrafast regenerative amplifier system. The femtosecond pump/Stokes photon pairs, used for impulsive excitation, are delivered by an external compressor operating on a ∼35% beam split of the uncompressed amplifier output (2.5 mJ/pulse). The picosecond 1.2 mJ probe pulse is produced via the second-harmonic bandwidth compression (SHBC) of the ∼65% remainder of the amplifier output (4.5 mJ/pulse), which originates from the internal compressor. The two pump/Stokes and probe pulses are spatially, temporally, and repetition-wise correlated at the measurement, and the signal generation plane is relayed by a wide-field coherent imaging spectrometer onto the detector plane, which is refreshed at the same repetition rate as the ultrafast regenerative amplifier system. We demonstrate 1 kHz cinematographic 1D-CARS gas-phase thermometry across an unstable premixed methane/air flame-front, achieved with a single-shot precision <1% and accuracy <3%, 1.4 mm field of view, and an excellent <20 µm line-spread function.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.Flight Performance and Propulsio
Spontaneous gene flow and population structure in wild and cultivated chicory, Cichorium intybus L.
No full textSpontaneous gene flow between wild and cultivated chicory, Cichorium intybus L., may have implications for the genetic structure and evolution of populations and varieties. One aspect of this crop-wild gene flow is the dispersal of transgenes from genetically modified varieties, e.g. gene flow from GM chicory to natural chicory could have unwanted consequences. With the purpose to identify and quantify crop-wild gene flow in chicory, we analysed introgression in 19 wild chicory populations and 16 accessions of chicory varieties and landraces distributed across Northern, Central and Mediterranean Europe. The analysis used 281 AFLP markers and 75 SSAP markers giving a total of 356 polymorphic markers. Results from model based assignments with the program STRUCTURE indicated many incidents of recent gene flow. Gene flow was observed both between cultivars and wild populations, between landraces and wild populations, between different wild populations as well as between cultivars. Population structure visualized by distance-based clustering showed a North–South geographical structuring of the wild populations, and a general grouping of the cultivars corresponding to known origin. The results indicated, however, that the structuring between the two groups of wild and cultivated types was weak. As crop and wild recipients are genetically close and genes are transferred between the two types rather frequently, focus on mitigating crop-wild gene flow should be increased, before transgenic varieties are cultivated openly

Projekta mērķis ir ne tikai sniegt grāmatvedības pakalpojumus, bet arī analizēt uzņēmumu darbību un izstrādāt ieteikumus darbības uzlabošanai. Darba autore uzskata, ka nozares pārstāvjiem ir būtiski jāpierāda sava nozīme un to kādam jābūt mūsdienu grāmatvedim. Grāmatvedis nav tikai persona, kura izdara konkrētus darbus, nodos atskaites, tas ir cilvēks, kuram labi jāpārzina nodokļu sistēma, finanšu vadīšana, jāspēj sniegt padomus uzņēmuma finanšu vadības uzlabošanai, kā arī jāspēj pielāgoties tehnoloģiju radītajām izmaiņām. Maģistra darbs apjoms ir uz 105 lappusēm, kas sastāv no 7 nodaļām, 17 pielikumiem, 22 tabulām un 7 attēliem. Darba izstrādē izmantoti 70 informācijas avoti.The general project idea is to establish the accountancy firm MJ Accountancy Ltd., which would provide full or half-cycle accountancy services including the processing of primary documentation, reports’ preparation, and providing of the accountancy consultations. The aim of the project is not only to provide accountancy consultations but also to deal with firms activity analysis and developing suggestions on their activity improvement. The author of the project supports the idea that the field representatives must constantly sustain the status of the accountant’s profession in current times. The accountant is not only the person who executes one’s regular duties and submits reports, but also the person who is competent in the field of taxes, financial management, able to advise on improvements in financial management, and above all able to adapt to the technological changes. The volume of the project is 105 pages, which includes 7 chapters, 17 appendices, 22 tables, 7 figures. 70 sources of information were used in master’s thesis
