Production of filamentous fungal biomass on waste-derived volatile fatty acids for ruminant feed supplementation and it's in vitro digestion analysisBouzarjomehr, Mohammadali January 2022 (has links)
Single cell proteins such as that of edible filamentous fungal biomass are considered as a promising sustainable source of animal feed supplementation. Filamentous fungi can be cultivated on different organic substrates including volatile fatty acids (VFAs) such as acetic, propionic, and butyric acids. These VFAs can be generated through the famous waste valorisation approach of anaerobic digestion (AD) as intermediate metabolites. This project investigates a sustainable approach for the production of animal feed supplementation through cultivation of fungal biomass on waste derived VFAs along with the in vitro analysis of fungal biomass digestibility as ruminant feed. In this regard, optimum conditions for the production of Aspergillus oryzae biomass on different VFAs effluents derived from anaerobic digestion process of food waste plus chicken manure (FWCKM) and potato protein liquor (PPL) at different pH, nitrogen sources, and feed mixture was studied. Accordingly, analyses showed that PPL has the highest biomass yield with 0.4 (g biomass/g consumed VFAs) based on the volatile solids (VS) by adjusting pH to 6.2. Furthermore, the digestibility of the produced fungal biomass is analysed by using three different in vitro digestion methods including Tilley and Terry (TT) method, Gas Production Method (GPM), and Nylon Bag Method (NBM) and the results are compared with the conventional feed (silage and rapeseed meal). Results obtained from different digestibility methods illustrate that different A. oryzae fungal biomass had approximately 10-15 % higher dry matter digestibility fraction compared to silage and rapeseed meal (reference feeds). Hence, these results revealed that A. oryzae fungal biomass can grow on VFAs effluents and produce protein-rich fungal biomass while this biomass has better digestibility compared to conventional feeds and confirmed the initial hypothesis of the study.

An explorative study of the technology transfer coach as a preliminary for the design of a computer aidJönsson, Oscar January 2014 (has links)
The university technology transfer coach has an important role in supporting the commercialization of research results. This thesis has studied the technology transfer coach and their needs in the coaching process. The goal has been to investigate information needs of the technology transfer coach as a preliminary for the design of computer aids.Using a grounded theory approach, we interviewed 17 coaches working in the Swedish technology transfer environment. Extracted quotes from interviews were openly coded and categorized. The analysis show three main problem areas related to the information needs of the technology transfer coach; awareness, communication, and resources. Moreover, 20 features for future computer aids were extracted from the interview data and scenarios and personas where developed to exemplify the future use of computer aids.We conclude that there is a need for computer support in the coaching process. Such systems should aid the coach in; awareness, aiding the coach to focus on meetings; communication, aid the coach to transfer commercialisation knowledge; and resources, aid the coach in accessing and delivering of resources to the coachee. However, it is imperative that the computer aids do not interfere with the coach current process; and that the computer aid is not seen as the sole solution.

Communication For a Space Sunshade SystemGranberg, Moa, Silfverberg, Nikolina January 2024 (has links)
By placing millions of space sunshades, of the order of 104 m2 at the sub-Lagrangian point L1',between the sun and Earth, solar radiation can be reduced enough to achieve the necessary temper-ature reduction to enable a slow down of the global warming. The vast amount of space sunshadesposes significant challenges on the communication system, as the probability of interference, whichcan distort information, increases with the number of simultaneously communicating units.This thesis aims to design a potential structure for the communication system that minimizesinterference as much as possible. To reduce the number of simultaneously communicating units, thesunshades are arranged in cell formation, where a mother is placed in the center with daughtersaround that only communicate with their specific cell mother. Direct communication betweenthe Earth and space sunshades is not possible as the interference from solar radiation can causesignificant distortion on the signals. Therefore, relay satellites are placed in orbit around thesub-Lagrangian point L1' at a sufficient distance to avoid the effects of solar radiation. Thus, thecommunication between the mothers and Earth is instead routed via the relay satellites. Sincecommunication between such a large number of entities in space has not been investigated before,this approach could provide a possible basic design framework for designing such infrastructure inthe future.

Die Deutfche Handwerkerbewegung Bis Zum Sieg Der GewerbefreiheitGoldschmidt, Ernst Friederich 03 October 1914 (has links)
Since then, the modern technology and its achievements has served the nature of trade to begin with, the middle class asks, whose core forms the hand worker movement, as the center of interest for science and politics. A craftsman movement, which is since 1848 rolling along, is today still not ended and the movement still exists and is alive. The hand worker asks, who arose to 1848 to meet, the chronic suffers who became so for decades. The physician, who saw a chronic person, can usually indicate not alone by looking at on welfare. One must look at the developing story for Evil and his life story to know the patient, in order to point to a way to recovery.More over the craftsmen and the craftsmen movement spoken about daily, indicated, in order to find a symptom, which makes itself too faulty in the given instant to be disturbingly most valid, is written to cure and to leave. A detailed connection, an end representation of the craftsmen movement is, however, up to the hour still not finished.In the following still the attempt of such a representation is to be made, for the too the period of 1848/1869.Our sources are particularly purely beside from national commission collections and congresses, are from the Craftsman, who are the other persons, who wanted to take position in the problem of the Craftsman or had daily papers, magazines and books, which are dedicated partly to individual branches of industry, partly the entire Handwork industry of the individual country. In addition to the facts, which follow from flight writings and from one-sided combat literature, come one sided in the pursuit of religion and on politics.An important source in the history of the Handworker Movement must be the legislation. As soon as the craftsmen movement forms, they accepted the seriously public damage the government issuing a new law could bring, an order in such a way could pour Oil onto the waves. The relation between cause and effect between the particulars far the craftsman movement can never clearly completely be, when a factor this important is let out. But not only the finished industrial law, also its developing story and its motives must be regarded, in order that the movement of the German Handwork Movement be completely known.
