A high diffraction efficiency and wide exposure latitude holographic processing method, capable of producing archival quality holograms is presented. It consists of a solution stage physical development on CPA-1, followed by a fixing stage. Holograms thus obtained have a wide exposure latitude and high diffraction efficiency. The method has been tried on 875-HD and 10E75-HD Agfa-Gevaert emulsions.

Non-targeted analysis (NTA) using high-resolution mass spectrometry without defined chemical targets has the potential to expand and improve chemical monitoring in many fields. Despite rapid advancements within the research community, NTA methods and data remain underutilized by many potential beneficiaries. To better understand barriers toward widespread adoption, the Best Practices for Non-Targeted Analysis (BP4NTA) working group conducted focus group meetings and follow-up surveys with scientists (n = 61) from various sectors (e.

Brazilian soils have distinctive characteristics to European and North American soils which are typically used to investigate pesticide fate. This study aimed to compare soil-water partition coefficient (K), reversibility of adsorption and degradation half-life (DT) of 5 pesticides covering a wide range of physico-chemical properties in contrasting Brazilian soils (Argissolo, Gleissolo, Latossolo and Neossolo) and a temperate (UK) alfisol soil, and to study their relationship with soil OM, clay and expandable clay content, CEC and pH. In addition, we used a novel laboratory test to evaluate sorption reversibility, the 3-Phase Assay (3PA).

Transpterygoid approaches to the skull base require dissection of the sphenopalatine artery, potentially compromising the option to harvest an ipsilateral nasoseptal flap (NSF) for reconstruction. In cases where other reconstructive options are limited, it may be necessary to utilize a NSF ipsilateral to the transpterygoid approach. Here, we describe the technique of NSF pedicle preservation with reconstruction outcomes.

Background: An inconsistent yet notable relationship between dietary habits and the risk of amyotrophic lateral sclerosis (ALS) has been previously established, with the causative nature of this relationship remaining uncertain. This study aims to explore the causal connections at a genetic level.
Methods: A two-sample Mendelian Randomization (MR) based analysis was conducted utilizing a comprehensive, publicly assessable Genome-wide association study (GWAS) database.

Per- and polyfluoroalkyl substances (PFASs) are widely used in consumer products and are easily encountered in daily life. PFASs that accumulate in the human body can negatively affect adolescent health. This study aimed to identify key exposure pathways that influence serum PFAS levels in Korean adolescents, using data from the Korean National Environmental Health Survey (2018-2020) cycle 4.
