title: Gonioreflectometric measurements in the mid-wavelength infrared range

description: A gonioreflectometer for the mid-wavelength infrared range was built to measure the emissivity of rough surfaces without contact. Gonioreflectometric measurements were conducted for several surface materials. Every HDF5-File contains the thermal images for a camera angle and incident angles from 1° to 90°, with open and closed chopper. For the camera angle of 15°, the data for incident angles from 3° to 87° degree is usable. Usable is the data from 1° to 87° for Camera angles of 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, 85°. The thermal images are available as temperature values in °C, radiance value in W/sr/m^2 and digital values. The radiance values are determined via Plancks Law. The rotation stage for the integrating sphere moves continuously with 10° per second, and the MWIR camera takes 10 HDR thermal image every second with the fastest possible frame rate to ensure the correctness of the angle.

title: Chemical Resistance of Regenerated Cellulose Fiber-Reinforced Bio-Polyamide 5.10 [Dataset]

description: Polyamides are known for their chemical resistance and are commonly used as matrix materials in glass fiber-reinforced composites (GFC) for automotive applications such as fuel caps and housings. To assess the potential of natural fiber-reinforced composites (NFC) as alternatives, this study investigates the chemical resistance of a bio-based polyamide (PA5.10) reinforced with regenerated cellulose fibers (RCF). Composites containing 20 wt.% RCF were produced using twin-screw extrusion, and standardized type 1A test specimens were injection molded. These were exposed to various fluids (distilled water, salt water, soap water, acid rain, rubbing alcohol, engine oil, ethanol, sodium hydroxide solution, and 2-propanol) for up to 168 hours. Subsequent analyses included tensile testing, FTIR spectroscopy, MVR, moisture measurements, and SEM imaging. Results revealed significant hydrolytic degradation, indicated by FTIR and decreased viscosity. Degradation was especially pronounced in acidic and alkaline media. A strong link was observed between increased moisture uptake and reduced mechanical properties. Chemical exposure led to notable damage in RCF composites, attributed to the moisture absorption of RCF and fiber degradation, as confirmed by SEM images. Loss of fiber-matrix adhesion further contributed to substantial declines in tensile strength and Young’s modulus. These findings highlight limitations in chemical resistance for RCF-reinforced bio-based polyamides, especially under harsh environmental conditions. This data set consists of the measured data from the conducted experiments as well as the data analysis.<br>In case you use the data please cite the corresponding article.

title: Assessing biodiversity of apricot landraces in Gilgit-Baltistan (Pakistan) using morphological and genetic traits (Microsatellite data)

description: For centuries, apricots (Prunus armeniaca L.) were used as a staple food in Gilgit-Baltistan (G-B), northern Pakistan where their high nutritional and medicinal value is still highly appreciated by many inhabitants. Here, many locally recognized landraces (referring to mainly undescribed varieties or cultivars) of apricot are available of which some are at risk of extinction, because of current human preferences replacing landraces by modern cultivars and other crop species. To assess the distribution, diversity, management and use of apricots in G-B, we made use of the region’s unique topography by employing the so-called ‘Dead-end valley sampling’ approach. It allowed to test the influence of market distance on morphological parameter classes. In 2021 and 2022, landrace richness, quantitative and qualitative morphological characteristics, and genetic diversity were investigated from 240 samples of several valleys. By employing 12 SSR markers we elaborated the identification of homonyms and synonyms of landraces. In addition, a total of 52 households from five valleys with three villages each as well as employees of two arboricultural research centres of Gilgit and Baltistan were interviewed.<br>Among the sampled landraces, 120 different landraces were named by farmers of which Halman, Habi, Karfo chuli and Shikanda were most frequent. The highest Simpson index (0.96) was found in Ishkoman, the most western valley studied. The high average genetic diversity (He = 0.729) across three identified genetic clusters, was supported by high excess of heterozygotes, indicated by negative inbreeding coefficients. Across-valley β-diversity was 0.737. Correlation between phenotypic and genetic dendrograms was moderate (r = 0.45, p = 0.001) indicating genetically linked fruit traits, warranting further investigation. Due to its considerable genetic and phenotypic diversity, Gilgit-Baltistan constitutes an important reservoir of apricot germplasm for future breeding programs. Promoting local landraces—potentially even recognized as distinct varieties—could help farmers diversify production and income sources while preserving the region’s historically significant bio-cultural heritage. To realize this potential, conservation and management measures combined with stakeholder-driven research and controlled breeding initiatives for effective monitoring will be essential.

title: Investigation of Synergistic Effects of UV Radiation and Elevated Temperatures on Regenerated Cellulose Fiber-Reinforced Bio-Polyamide 5.10 Composites and the Contribution of UV Stabilizers to their Stability [Dataset]

description: This study investigates the thermo- and photo-oxidative degradation behavior of a bio-based polyamide (PA) 5.10, both neat and 20 wt.% regenerated cellulose fiber-reinforced (RCF). In addition, these materials were modified with two different UV stabilizers, AddWorks IBC760 (IBC), a hindered amine light stabilizer, and LUBIO UV16 (LUBIO), an UV absorber. 168 hours of storage at temperatures of 23 °C, 50 °C, 70 °C to 90 °C at 50 %rH, with and without UV exposure of 1000 W/m², revealed significant degradation effects both in neat and LUBIO-stabilized batches, including molecular chain splitting processes, embrittlement, reduction in surface polarity and pronounced yellowing. In contrast, the IBC provided superior stabilization, maintaining thermal and mechanical properties as well as color stability. RCF-reinforced PA 5.10 exhibited moisture-induced plasticization, increasing ductility as well as aging-induced embrittlement at elevated temperatures. SEM imaging confirmed an increased share of fiber ruptures in the UV exposed neat RCF-composites, while IBC-stabilized specimens preserved the high amount of fiber pull-outs. Melt volume rate measurements demonstrate the reduction in molecular weight due to the thermo- and photo-oxidative degradation. A linear polynomial regression was also used to demonstrate the characteristic degradation mechanisms of polyamide. Overall, the IBC-stabilized batches show a significant stabilization effect across all tested storage conditions. These findings highlight the potential of UV-stabilized RCF-reinforced PA 5.10 composites as sustainable replacements for petro-based polyamide composites in applications requiring long-term resistance to thermo- and photo-oxidative stress. This data set consists of the measured data from the conducted experiments as well as the data analysis.<br>In case you use the data please cite the corresponding article.

title: Effect of Various Organic Mulches on Aphids, Their Predators, and Potato Virus Transmission [Dataset]

description: Potato virus Y (PVY) and potato leafroll virus (PLRV) are two viruses of major economic importance in potato cultivation. Several studies have demonstrated that the transmission of non-persistently transmitted PVY can be reduced through the use of straw mulch. However, little is known about the impact of other mulch materials and their influence on persistently transmitted PLRV. The impact of triticale/ vetch, grass/clover, grass silage, and straw mulch was thus investigated in five field trials. Aphid flight activity was monitored using yellow water traps, and vector pressure was calculated based on species-specific relative efficiency factors. The occurrence of aphids and their predators on potato plants were assessed by visual counts. Harvested tubers were tested for their virus incidence for both PVY and PLRV. The results demonstrated that all mulch treatments significantly reduced aphid landings by 30–75% compared to the unmulched control, with the greatest reduction observed for Myzus persicae. Consequently, PVY vector pressure was substantially lower in mulched plots. Mulching with triticale/vetch, grass/clover, and straw significantly decreased PVY incidence by up to 75%. However, the overall incidence of PLRV was too low to make a conclusive statement about the effect of mulch on PLRV transmission. Aphid abundances and numbers of aphid predators on the plants were generally lower in mulched plots. These results demonstrate that organic mulches can be an effective cultural control measure against aphid-transmitted potato viruses, as they disrupt vector landing early in crop development and potentially reduce within-field spread.

title: Can the assessment of skin lesions and keel bone damage at the slaughterhouse tell about hen welfare on-farm? [Dataset]

description: Data were collected in 20 commercial laying hen flocks at three different time-points. Before depopulation on the farm, at the slaughterhouse arrival and at the slaughter line after defeathering. Included were different genetics of conventional as well as organic housing systems. Aim of the study was to develop an automatically camera system for the detection of keel bone damage and skin lesions each. As a part of it we had to check if prevalences assessed at the slaughter line are equal to those existing on farm.
