Wohnen gleich Wohnen?
No full textÜber die Unterschiede zwischen „der Stadt“ und dem „ländlichen Raum“ wurde in den letzten Jahrzehnten viel publiziert und auch kommuniziert. Die Bandbreite, welche zumeist die Unterschiede beispielhaft beschreibt, ist denn auch mannigfaltig: Infrastrukturausbau, Pendleraufkommen, Gehaltsunterschiede, Fördermittel, „abgehängt vom ÖPNV“. Schlagworte wie sie regelmäßig in politischen Kommentaren, im Wahlkampf oder bei den Diskussionen zum Länderfinanzausgleich vorkommen. Auf die Immobiliensituation bezogen, werden primär die unterschiedlichen Kauf- und Mietpreise, Grundstückverfügbarkeiten und „das Haus im Grünen, welches dort noch bezahlbar ist“ als differenzierende Argumente aufgeführt. Gemein wiederum ist allen die Daseinsgrundfunktion Wohnen – umgangssprachlich: das Dach über dem Kopf
Schwingungsverhalten von Holzdecken – Erfahrungen mit einem XXL-Deckenprüfstand
No full textVon Januar 2021 bis Juni 2023 arbeitete die Hochschule Biberach in Kooperation mit der PIRMIN JUNG Deutschland GmbH, Remagen, an der Entwicklung eines leichten, schwingungsoptimierten Holzdeckensystems mit Unterzügen für große Spannweiten. Es gibt bereits Forschungsarbeiten, die sich mit dem Schwingungsverhalten von Holzdecken beschäftigen. Der neue Fokus in diesem Projekt liegt vor allem auf der Größe des untersuchten Systems. Bauwerke wie Schulen, Verwaltungs- und Bürogebäude erfordern Decken mit sehr großen Stützenabständen und daher sehr großen Spannweiten. Es wurden unterschiedliche Deckensysteme mit unterschiedlichen Aufbauten, Lagerungsbedingungen und Spannweiten gemessen und bewertet. Das Forschungsprojekt umfasste theoretische und praktische Betrachtungen des Schwingungs- und Dämpfungsverhalten von Holzdecken mit großen Spannweiten und Unterzügen

No full textObjectives: To determine whether the site of measurement (over respiratory mucosa (RM) or within the olfactory cleft [OC]), olfactory testing, or repeated pH testing affects pH measurements and whether OC pH affects olfactory function.
Methods: This cross‐sectional study included 62 healthy adults (38 women, median age: 24 years). They underwent the following measurements: intranasal pH (Restech Dx‐pH; Respiratory Technology Corp., Houston, USA) and olfaction (“Sniffin' Sticks” Odor Identification Test [OdorId]; Burghart, Holm, DE). Participants were divided based on the following: sites of testing (RM [n= 27] vs. OC [n=35]); order of testing (olfactory testing [OdorId] between two pH tests [pH‐OdorId‐pH, n=17] versus two pH tests separated by a 20‐min interval followed by olfactory testing [pH‐pH‐OdorId; n=18]). Comparisons between the first and second pH tests were also performed.
Results: OC pH measurements were significantly lower than RM pH. Repeated pH testing resulted in subsequently more alkaline measurements, while olfactory testing had no effect. Odor identification scores correlated with OC pH but not with RM pH. In an exploratory linear regression model, OC pH predicted 18% of the variance in OdorId scores and was a significant negative predictor of OdorId performance (as pH increases, OdorId decreases).
Conclusion: The OC pH is more acidic compared to that over the RM. Increased acidity in the OC was related to better olfactory function, warranting further investigation in olfactory dysfunction.

Enabling Data-Driven Collaboration: Leadership, Culture, and Knowledge Management in the Digital Enterprise
No full textAs organizations pursue data-driven goals, transforming into data-driven organizations (DDOs) has become key to achieving sustainable competitive advantage through better decisions, innovation, and efficiency. At the core of this shift lies the data-driven culture (DDC), which enables organizations to treat data as a strategic asset. This paper explores how leadership, rganizational culture, and knowledge management interact to build such a culture. While advances in data technologies have expanded data’s availability and value, true transformation depends on embedding data-driven thinking across all levels. Drawing on interdisciplinary literature and expert interviews within a German multinational, the study identifies enablers and barriers to DDC implementation, emphasizing leadership competencies, cultural alignment, and collaborative knowledge processes. The findings highlight that effective leadership and adaptive culture—supported by structured knowledge sharing—are essential for successful data-driven transformation and long-term competitiveness
Investigating the Compressive Strength of Sisal- Reinforced High-Compressed Earth Blocks
No full textThe current research presents the results of an experimental inves-
tigation of the compressive performance of sisal-reinforced earth under high compression conditions. Developing alternative sustainable and environmen-tally friendly construction materials to conventional materials has become a fundamental research area. Compressed Unstabilized Earth Blocks (CUEBs), particularly, represent an eco-friendly alternative to the cement stabilized Compressed Earth Blocks (CEBs) while providing improved performance over traditional materials, predominantly utilizing earth. Sisal fibers are
added to earth blocks to enhance their mechanical performance and serve as secondary reinforcements and crack arresters, hence minimizing the defects that are experienced when working with these blocks. In this experimental study, the earthen mixture is mixed with sisal fibers 0.5 %, 0.75 %, 1.0 %, 1.25 %, 1.5 %, and 2.0 % by weight of soil, respectively, in three batches of varying fiber lengths of 2 mm, 4 mm and 6 mm. The main goal of the study was to determine which fiber length and at what admixture content the best mechanical qualities after compressive strength testing would be achieved.
The results obtained showed the combined effect of the sisal fibers and the high compression on the compressive strength properties of the CUEBs material. The findings indicated that the most effective configuration for attaining high-strength performance is the 6mm fiber length, while the optimum admixture proportion was found to be 1.25 % sisal admixture composition. However, both Modulus of Elasticity E1 (Tangential Modulus) and E2 (Secant Modulus) appeared to be optimized at lower admixture percentages (0.5 %-0.75 % sisal)
Analytical modelling approach of ground freezing and thawing around ground heat collectors
No full textGround heat collectors represent shallow geothermal devices that are buried in the upper metres of the ground with strong thermal coupling to ground surface. Therefore, during seasonal operation, heat extraction in winter can cause temporal freezing of the soil surrounding the collector. The transient latent heat transfer during freezing and thawing can be crucial for the performance of a collector, and it adds complexity to the model-based representation of the devices. Here, a novel analytical model is presented that accounts for these processes and simulates the evolution of thermal ground conditions during operation of different collector variants. It combines heat source-based solutions with thermal power balancing depending on a given collector geometry and temporal superposition for varying heat loads. By comparison with high-resolution numerical model results, the obtained fast analytical predictions represent the thermal regime around horizontal pipe installations and vertical planar trench collectors within seconds very well, achieving temperature deviations of less than 1.4 K and accuracies over 85.6% for predicting of the thickness of the frozen ground. This regime is inspected in particular with respect to collector wall temperature and the maximum horizontal extension of the frozen soil. The findings demonstrate the suitability of the new model framework to be used in the planning and design phase for optimal layout of collectors, as well for straightforward representation of complex freezing and thawing processes during operation.Please check and confirm that the authors and their respective affiliations have been correctly identified and amend if necessary.The affiliations are correctly.
