Abstract:
Limited data exist concerning the effects of exercise training on cellular oxidative capacity in the diaphragm of senescent animals. In this study we examined the changes in cellular oxidative capacity, muscle cell cross-sectional area (CSA), and capillarity within the costal diaphragm of senescent animals after a 10-wk endurance-training program. Twelve 24-mo-old female Fischer 344 rats were divided into either a sedentary control group (n = 6) or exercise training group (n = 6). The trained animals exercised on a motor-driven treadmill (60 min/day, 5 days/wk) at a work rate equal to approxim

In order to investigate the steel fiber parameters on the damage characteristics and crack evolution of cellular concrete materials, uniaxial compression–acoustic emission combined tests were carried out on steel-fiber-reinforced cellular concrete (SFRCC) with different steel fiber contents (0%, 0.5%, 1%, 1.5%, and 2%) and different porosities (10% and 20%). The material damage evolution characteristics were analyzed by acoustic emission parameters and IB values, and the crack types were identified using Gaussian mixture clustering method (GMM) pairs.

The paper presents studies on the properties of various types of micro-reinforcing fibers to assess their role and effectiveness in the structure formation of the cellular composite. Based on the data on the weight loss after exposure in a model medium of cement, analysis of the alkali resistance of fibers of five different types – basalt fiber, heat-treated basalt fiber, polymer fiber and glass fibers from two different manufacturers – was carried out. It is shown that the fibers have a sufficiently high durability in the medium of hardening cement, which is expressed by a relatively insignif

Abstract:
Muscle fibers that power swimming in the blue crab Callinectes sapidus are <80 μm in diameter in juveniles but grow hypertrophically, exceeding 600 μm in adults. Therefore, intracellular diffusion distances become progressively greater as the animals grow and, in adults, vastly exceed those in most cells. This developmental trajectory makes C. sapidus an excellent model for characterization of the influence of diffusion on fiber structure. The anaerobic light fibers, which power burst swimming, undergo a prominent shift in organelle distribution with growth. Mitochondria, which require O2 a

The results of studies of the physical and mechanical properties of heat-efficient foam concrete, as well as fine-grained concrete, are summarized.

The determination of physical and mechanical properties corresponds to GOST 180-2012.

Recent advancements in construction materials development have involved the utilization of plant-based natural fibers such as kenaf, sisal, coir and banana to replace conventional fibers such as carbon, steel, polypropylene and aramid. However, the main issue with using these fibers is the alkaline cement matrix's durability and compatibility due to high water absorption. Hence, this research focuses on the use of alkali treatment of banana fibers to enhance the mechanical properties of cellular lightweight concrete (CLC).

Escherichia coli is used to clone a "template" protein, Gd20, which will cooperatively self-assemble with two "adder" proteins, P7Q and P7S, to yield two different large amyloid fibers. Atomic force microscopy (AFM) is used to image the fibers and AFM tip approach/retraction force is used to quantify molecular packing in the fibers.

A two-term Prony series expansion of the quasi-linear viscoelastic model was chosen to model the viscoelastic properties of the collagen fibers.

Abstract:
A regular pattern called crimp is an essential morphological feature of collagen fibers in native tendon. In this study, the direct crimp writing (DCW) and zig-zag pattern writing (ZPW) were developed based on electrohydrodynamic jet printing (E-jetting) process to fabricate the crimped fibers. For the DCW process, the fibers were deposited with the linear movement of stage, and the crimps (crimp angle: ∼ 46°; crimp length: ∼630 μm; fiber diameter: ∼100 μm) were formed from the spinning of fibers. For the ZPW process, the fibers was printed via the zig-zag moving path, and the effects of a vit

Abstract:
Abstract The role of porosity on failure resistance of 3-D woven fiber reinforced epoxy panels under dynamic loading condition is investigated. Incident and residual velocities are measured to determine the energy absorption by the target. Material behavior segregates by porosity, and the more highly porous samples absorb a greater amount of specific energy. The reason for this may be due to the deflection of matrix cracks by pores or due to the greater flexibility of the fibers to absorb energy through tensile straining. Although porosity is generally an undesirable property in textile compos

Abstract:
Fiber photometry uses spectroscopy to monitor the cellular dynamics in the cell or organ of interest in vivo. It uses photons from the light of a specified wavelength to trigger cells at the region of interest, enabling researchers to monitor the dynamics at a precise location in real-time. Unlike the patch clamp, fiber photometry is used on living animals. It enables researchers to investigate how specific cellular ions or proteins in a particular cell or organ respond to a certain trigger or stimulant in real-time and over some time. These abilities make fiber photometry highly relevant to n

Abstract:
Satellite communication plays an important role in the global connectivity ecosystem. It connects rural and remote populations, provides backhaul connectivity to mobile cellular networks, and enables rapid communications for emergency and disaster responses. Low Earth orbit constellations may prove to be transformational to the connectivity landscape based on their global coverage and their suitability for areas not served by fiber optic cable networks. The Asian Development Bank’s developing member countries are well placed to benefit from this expansion of internet connectivity. It will be p

Abstract:
Our project focuses on gene expression and proteomics of the whitefly Bemisia tabaci (Gennadius) species complex in relation to the internal anatomy and localization of expressed genes and virions in the whitefly vector, which poses a major constraint to vegetable and fiber production in Israel and the USA. While many biological parameters are known for begomovirus transmission, nothing is known about vector proteins involved in the specific interactions between begomoviruses and their whitefly vectors. Identifying such proteins is expected to lead to the design of novel control methods that i

Abstract:
Besides new material solutions, innovative processing technologies are key for working towards a more sustainable future for bead foam products. Compared to standard steam chest molding, innovative radio frequency (RF) welding shows great potential based on its direct energy input, which results in reduced energy consumption. Thus, the present study provides fundamental insights into the correlation of dielectric properties of expanded thermoplastic polyurethane (ETPU) bead foams with the processing behavior.
