Effect of nanotechnological products on compression parallel to the fibers and dynamic bending strengths of laminated materials (Lvl and Glulam)

open access: yesTurkish Journal of Forestry
In this study, the effect of resins modified with nanoproducts on some mechanical properties of laminated materials was investigated. For this purpose, LVL and unstructured GLULAM laminated materials were obtained by gluing test specimens prepared from ...

Venoarterial modified ultrafiltration versus conventional arteriovenous modified ultrafiltration during cardiopulmonary bypass surgery

open access: yesAnnals of Saudi Medicine, 2014
BACKGROUND AND OBJECTIVES: Different types of modified ultrafiltration (MUF) systems evaluated showed that none of the MUF techniques adhered to the normal venous to arterial blood flow dynamics.

Potential of Bee Pollen as a Nutraceutical And/Or Functional Ingredient for Metabolic Syndrome Management: In Vitro Antioxidant, Anti‐Inflammatory, and Digestive Enzyme Inhibitory Activities

open access: yesFood Chemistry International, Volume 2, Issue 3, Page 465-476, September 2026.
Bee pollen samples from China and Spain exhibited in vitro antioxidant, anti‐inflammatory, and digestive enzyme inhibitory activities due to their composition, suggesting their potential as a nutraceutical or functional ingredient to help counteract oxidative stress, chronic inflammation, and metabolic disorders.

Nighttime above‐the‐MUF HF propagation on a midlatitude circuit [PDF]

open access: yesRadio Science, 2008
HF radio propagation was observed regularly during the night at frequencies above the classical Maximum Usable Frequency (MUF) on the circuit from Fort Collins, Colorado, to Boston, Massachusetts, during 2003 (McNamara et al., 2006). This propagation was attributed to above‐the‐MUF propagation, in the sense of normal refraction by over‐dense regions in

Seasonal dynamics of soil biological properties under long‐term cereal rye cover cropping in a no‐till corn–soybean rotation in Southeastern Indiana

open access: yesSoil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Cover crops are widely used in corn (Zea mays L.)–soybean (Glycine max) systems to improve soil health, yet seasonally dynamic responses of soil biological properties to long‐term cover cropping remain not fully understood, particularly in the low‐organic matter Alfisols of the eastern Corn Belt.

A Nuclear Material Accounting Simulation Model for Spent Fuel Reprocessing Facility

open access: yesJournal of Isotopes, 2022
In order to optimize the nuclear material accounting of spent fuel reprocessing facilities and find the main factors of the material unaccounted for (MUF), a numerical simulation model based on nuclear material accounting perspective is built, which ...

Degradation capability of the coastal environment adjacent to the Itata River in central Chile (36.5° S) [PDF]

open access: yesBiogeosciences, 2011
The response of the coastal ocean influenced by both river discharges and inputs of photosynthetically derived organic carbon product of upwelling, was evaluated by estimating rates of microbial hydrolysis of macromolecules with the goal of estimating ...

Cropping system and nitrogen fertilization modulate soil enzyme kinetics

open access: yesSoil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract The decomposition of soil organic matter and nutrient cycling are largely mediated by extracellular enzymes, yet the effect of soil management on enzyme kinetic (Michaelis constant [Km] and maximum velocity [Vmax]) remains poorly understood.

Exploring the Applicability of Three Popular Models for Predicting the Received Field Strength of HF Sky‐Wave Propagation and Communication

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract High‐frequency (HF) radio signals rely on ionospheric reflection and refraction to enable long‐range and transcontinental transmission, making them essential for military command, emergency response, and strategic communications. The received field strength is a key parameter for quantifying propagation conditions and optimizing HF circuit ...
