Stable Sb exhibits a rhombohedral structure, often referred to as distorted primitive cubic, with each Sb atom having three short and three longer first neighbor bonds. However, this crystal structure can also be interpreted as being layered, putting emphasis on only three short first neighbor bonds. Therefore, temperature-dependent extended X-ray absorption fine structure (EXAFS) spectroscopy is carried out at the Sb K-edge in order to obtain more detailed information on local structural and vibrational properties.

The rhizosphere, the soil zone surrounding plant roots, serves as a reservoir for numerous beneficial microorganisms that enhance plant productivity and crop yield, with substantial potential for application as biofertilizers. These microbes play critical roles in ecological processes such as nutrient recycling, organic matter decomposition, and mineralization. Plant growth-promoting rhizobacteria (PGPR) represent a promising tool for sustainable agriculture, enabling green management of crop health and growth, being eco-friendly alternatives to replace chemical fertilizers and pesticides.

Article Synopsis
- The study developed a mathematical model to evaluate total risk in imaging procedures by considering both radiation and clinical risks, addressing a gap in previous research.
- The findings indicate that clinical risk is significantly greater than radiation risk, with a minimum 400% excess across all demographics analyzed.
- The results suggest that optimizing radiation doses in CT exams may require increasing doses in many cases, particularly benefiting certain populations like Asians, while emphasizing the potential harms of excess radiation reduction.
Vitamin D and other micronutrient deficiency prevention: the role of data in informing national, regional, and global policy.

The World Health Organisation describes micronutrient deficiencies, or hidden hunger, as a form of malnutrition that occurs due to low intake and/or absorption of minerals and vitamins, putting human development and health at risk. In many cases, emphasis, effort, and even policy, revolves around the prevention of deficiency of one particular micronutrient in isolation. This is understandable as that micronutrient may be among a group of nutrients of public health concern.

Objectives: The inferior vena cava (IVC) is one of the most frequent injured intra-abdominal vessels and its treatment requires prompt action. Despite advances in reanimation in last decades, there has not been proportional improvement in IVC mortality. This report aims to discuss the mortality predictive factors including the adherence to balanced reanimation and damage control surgery (DCS) in daily trauma assistance, their repercussions on outcomes, comparing our institution outcomes to literature.
