Locally grown lavender was collected fresh for this purpose, and its oil was extracted using the cold-press method. The resultant LEO and LM and whole lavender (WL) were added to dairy cow concentrate feed at 0\%, 0.05\%, and 0.10\%, and their effects on vitro gas production values and gas concentrations were subsequently assessed. Out of the 30 bioactive compounds isolated from LEO, linalool and linalyl acetate were the most common—accounting for 70.4\% of the total. The lavender dose had a significant influence on gas production for up to 12 h. No significant variations were found across the lavender forms when gas kinetics, in vitro degradability, and predicted energy values were compared. The addition of WL to the concentrate feed of dairy cows produced the greatest quantities of methane, carbon dioxide, and hydrogen sulfide, whereas LEO resulted in the lowest values. In contrast, no significant difference in ammonia content was found across the various lavender forms added into dairy cow concentrate feed. The results of this research suggest that adding 0.05-0.10\% LM and LEO to concentrate feed may decrease greenhouse gas emissions from dairy cows.}, subject = {lavender}, language = {en} } @inproceedings{ValckenborgBergerUjvarietal., author = {Valckenborg, Roland and Berger, Karl A. and {\´U}jv{\´a}ri, Guszt{\´a}v and Eder, Gabriele C. and Gaisberger, Lukas and Tabakovic, Momir and Polo Lopez, Christina S. and Boddaert, Simon and del Buono, Matteo and Mart{\´i}n Chivelet, Nuria and Sanz Martinez, Asier and Kim, Jun-Tae and Gerd Imenes, Anne}, title = {COMPARISON OF IEC 61853-1 MATRIX EVALUATIONS BASED ON INDOOR AND OUTDOOR MEASUREMENT DATA FROM PVPS TASK 15 BIPV ROUND-ROBIN}, series = {38th European Photovoltaic Solar Energy Conference Proceedings, September 6-10, 2021}, booktitle = {38th European Photovoltaic Solar Energy Conference Proceedings, September 6-10, 2021}, subject = {Measurement}, language = {en} } @misc{BucherAburaiaMarkletal., author = {Bucher, Christoph Michael and Aburaia, Mohamed and Markl, Erich and Engelhardt-Nowitzki, Corinna and Lackner, Maximilian and Gonzales-Gutierrez, J. and Lammer, Helmuth}, title = {Continuous fiber reinforced freeform 3D printing}, subject = {Additive Manufacturing}, language = {en} } @article{MarklLackner, author = {Markl, Erich and Lackner, Maximilian}, title = {Devulcanization Technologies for Recycling of Tire-Derived Rubber: A Review}, series = {Materials}, volume = {13}, journal = {Materials}, number = {5}, doi = {10.3390/ma13051246}, abstract = {In general, composite materials are difficult to recycle. Tires belong to this class of materials. On top, one of their main constitutents, vulcanized rubber, is as elastomer, which cannot be remolten and hence is particularly challenging to put to a new use. Today, the main end-of-life routes of tires and other rubber products are landfilling, incineration in e.g., cement plants, and grinding to a fine powder, generating huge quantities and indicating a lack of sustainable recycling of this valuable material. True feedstock recycling is not feasible for complex mixtures such as tires, but devulcanization can be done to reactivate the cross-linked polymer for material recycling in novel rubber products. Devulcanization, i.e., the breaking up of sulfur bonds by chemical, thermophysical, or biological means, is a promising route that has been investigated for more than 50 years. This review article presents an update on the state-of-the art in rubber devulcanization. The article addresses established devulcanization technologies and novel processes described in the scientific and patent literatures. On the one hand, tires have become high-tech products, where the simultaneous improvement of wet traction, rolling resistance, and abrasion resistance (the so-called "magic triangle") is hard to achieve. On the other hand, recycling and sustainable end-of-life uses are becoming more and more important. It is expected that the public discussion of environmental impacts of thermoplastics will soon spill over to thermosets and elastomers. Therefore, the industry needs to develop and market solutions proactively. Every year, approximately 40 million tons of tires are discarded. Through the devulcanization of end-of-life tires (ELT), it is possible to produce new raw materials with good mechanical properties and a superior environmental footprint over virgin products. The devulcanization process has become an interesting technology that is able to support the circular economy concept.}, subject = {rubber devulcanization}, language = {en} } @article{BesharatiPalangiNiazifaretal., author = {Besharati, Maghsoud and Palangi, Valiollah and Niazifar, Masoumeh and Esen, Selim and Lackner, Maximilian}, title = {A Comprehensive Analysis of Cinnamon, Flaxseed, and Lemon Seed Essential Oils' Effects on In Vitro Gas Formation and Nutrient Degradability in Diets}, series = {Fermentation}, volume = {9}, journal = {Fermentation}, number = {6}, doi = {10.3390/fermentation9060504}, abstract = {This study aimed to assess the impact of essential oils (EOs) on in vitro gas formation and the degradability of dairy and beef cattle diets. This study also aimed to investigate the effects of different types of EOs on nutrient utilization and rumen microbial activity. The current study was conducted using a fully randomized design consisting of eight experimental treatments, including two control treatments without any additives, and treatments with cinnamon essential oil (CEO), flaxseed essential oil (FEO), and lemon seed essential oil (LEO) at a concentration of 60 mg/kg fresh mass. Two control treatments were used, one with alfalfa silage and dairy concentrate (DC, CON-DC) and the other with alfalfa silage and fattening concentrate (FC, CON-FC). Gas formation, dry matter (DM) digestibility, crude protein (CP) digestibility, effective degradability (ED), and soluble fractions of DM and organic matter (OM) were evaluated. CEO had a substantial effect on gas formation (p < 0.05). When EOs were added to the diets, they increased dry matter digestibility after 24 h of incubation as compared to control treatments. After 24 h of incubation, FCCEO and FCFEO had the highest CP digestibility among the diets. FCLEO considerably enhanced ED, as well as the soluble fraction of DM (a) at a passage rate of 2\% per hour. Treatment with FCCEO resulted in a significant increase in soluble fractions compared to the control diets. At a passage rate of 2\% h, DCCEO had the maximum ED value. When EOs were introduced to the diet, they dramatically decreased the insoluble portion of CP (b). Compared to the control treatments, gas production was significantly lower in the presence of LEO (FCLEO; p < 0.05). The addition of EOs to cattle diets may increase nutrient utilization and enhance rumen microbial activity. EOs extracted from lemon seeds (at a dose of 60 mg/kg of diet) lowered gas production in both dairy cattle and fattening diets.}, subject = {Digestibility}, language = {en} } @article{PalangiTaghizadehAbachietal., author = {Palangi, Valiollah and Taghizadeh, Akbar and Abachi, Soheila and Lackner, Maximilian}, title = {Strategies to Mitigate Enteric Methane Emissions in Ruminants: A Review}, series = {Sustainability}, volume = {Vol. 14}, journal = {Sustainability}, number = {Issue 20}, doi = {10.3390/su142013229}, abstract = {Methane is the main greenhouse gas (GHG) emitted by ruminants.

Furthermore, the authors will attempt to discuss the drawbacks of the strategies in terms of animal health and performance reduction as well as the concept of feed and energy loss, adding an economic perspective to methane emission mitigation which is in the farmers' direct interest. As a whole, many factors are effective in reducing undesired methane production, but this is definitely a complex challenge.
