Background: Yerba mate (YM) drinking is associated with higher lumbar spine and femoral neck bone mineral density (BMD) in postmenopausal women. We analyzed its effect on total hip BMD and reported the contribution of th...

OBJECTIVE: The prevalence of atherosclerosis and osteoporosis increase with age. An association has been demonstrated between cardiovascular diseases and low bone mineral density. We aimed to investigate the association ...

Dual-energy X-ray absorptiometric bone mineral density (DXA BMD) is a strong predictor of fracture risk in untreated patients. However, previous patient-level studies suggest that BMD changes explain little of the fractu...

In recent years, generative artificial intelligence represented by large language models (LLMs) and multimodal large language models (MLLMs) has achieved remarkable progress. These ultra-large-scale and complex models im...

This study aims to determine the comparison of oil yields obtained from processing HDPE plastic waste by comparing quantitatively and qualitatively the fuel oil produced. The processing of plastic waste into oil by pyrol...

Identifying candidates with high crystal density using Quantitative Structure-Performance Relationship (QSPR) models is a primary task in screening energetic molecules. However, due to the scarcity of high-density traini...

Abstract Effective evacuation strategies are critical for preventing stampedes in large-scale, high-density crowd management. This paper develops a second-order sliding mode controller within a distributed parameter syst...

Tooth extraction is a common dental procedure. Osteoblasts (bone-forming cells) and collagen are key indicators of wound healing following tooth extraction. Hydroxyapatite is a calcium-rich material that promotes the sec...

O objetivo neste trabalho foi avaliar o manejo, as características eritrocitárias e o nível de glicose sanguínea de pacus (Piaractus mesopotamicus) estocados em diferentes densidades em tanques-rede. Foram utilizados...

This study focuses on the detonation performance and equation of state (EOS) of a low-density composite explosive mixed in a certain proportion of PBX-9502 powder and 502 glue. The theoretical analysis method was used ba...

One hundred and fourteen hectares of a "terra-fiirme" rain forest 70 km north of Manaus, Amazonas, Brazil, were surveyed for leaf-cutting ant colonies (Atta spp). One half of this area was in isolated forest fragments (s...

Density and surface tension for Sn1-xNix(x = 0; 0,05; 0,1) have been measured by means of sessile dropmethod. Temperature dependences of these parameters as well as influence of Ni-atoms on density and surfacetension wer...

Osteoporosis is a bone disease characterized by reduced bone mass and damage to the microarchitecture of bone tissue. One of osteoporosis types is primary type-1 osteoporosis or postmenopausal osteoporosis due to estroge...

This paper analyzes the effect of noise in type-II and type-III intermittency, with respective local Poincaré maps of xn+1=(1+ε)xn+(1-ε)xn3 and xn+1=-(1+ε)xn-axn3 (a> 0). We develop a method to obtain the noisy reinj...

We report experimental results of the speed-density relation emerging in pedestrian dynamics when individuals keep a prescribed safety distance among them. To this end, we characterize the movement of a group of people r...

The plasmasphere contains rich small-scale structure that plays a key role in regulating wave propagation and mass transport in the inner magnetosphere, yet the evolution of plasmaspheric density ducts remains poorly und...

Background: F2 resource populations have been used extensively to map QTL segregating between pig breeds. A limitation associated with the use of these resource populations for fine mapping of QTL is the reduced number o...

ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their eco...

The behavioral response of a parasitoid shows the effect on host parasitism patterns at a given host distribution. As a result, an increase or decrease in parasitism intensity according to local host densities is found. ...

Tooth extraction is a common treatment in dental practice. However, complications such as bleeding or dry socket may occur during healing process. Pangas catfish (Pangasius djambal) gelatin contains glutamine which could...

ABSTRACT The purpose of this study was to determine if in ovo feeding with 25(OH)D3 could influence the incubation parameters of bone mineral composition, mineral density, and bone breaking strength in post-hatch broiler...

The effects of humidity on density altitude are quantified in detail and graphically represented as a function of temperature and dew-point temperature for ease of use in professional aviation education. A ten-year clima...

The method of dispersion correction as an add-on to standard Kohn-Sham density functional theory (DFT-D) has been refined regarding higher accuracy, broader range of applicability, and less empiricism. The main new ingre...
