“…Like other organs of the human body, the eyes exhibit diferences between females and males [17]. As previously reported, female patients in this study demonstrated shorter AL with consequently shallower ACD and steeper corneas than male patients [7,8,11,[13][14][15][16][17][18][19][20][21]. Furthermore, this is the frst study that has documented all aforementioned genderrelated diferences according to diferent age groups.…”

“…On the other side, we have also found a decreasing trend in ACD with steeper corneal curvature [ 7 , 8 , 11 , 12 ]. Regardless of race, there is also a decreasing trend in ACD with age, which could be attributed to age-related lens thickening [ 8 , 12 , 13 , 16 , 18 – 22 ]. This highlights another supposed mechanism of emmetropisation, the lens thins (or decreases in power) as the eye gets longer (myopic) and thickens (or increases in power) as the eye gets shorter (hyperopic) [ 19 ].…”

“…Several previous studies have reported the biometric characteristics of cataract surgery candidates from diferent parts of the world. Age-related changes in corneal astigmatism prevalence and characteristics, as well as ocular biometric parameters, have been documented [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Furthermore, there have been certain diferences in ocular biometry between male and female patients reported [7,8,11,[13][14][15][16][17][18][19][20][21][22].…”

Purpose. The aim of the study is to determine the distribution and mutual relationship of ocular biometric parameters, as well as to evaluate gender- and age-related differences in patients undergoing cataract surgery in Bosnia and Herzegovina. Materials and Methods. It was a retrospective cross-sectional study of consecutive patients who underwent cataract surgery between January 2017 and December 2021 in a tertiary care clinic. All biometric measurements were performed using the optical biometer OA-2000 (Tomey, Nagoya, Japan). Results. The study evaluated 1278 eyes from 1278 consecutive cataract patients. The average age of all included patients was 69.4 ± 9.98 (range 40–96). A total of 672 eyes (52.58%) were from females. The mean axial length (AL), anterior chamber depth (ACD), lens thickness (LT), and mean keratometry were 23.46 ± 1.18 mm, 3.17 ± 0.40 mm, 4.54 ± 0.48 mm, and 43.42 ± 1.55D, respectively. Corneal astigmatism of ≥1D, >2D and >3D was found in 33.4%, 7.8% and 2.5% patients, respectively. Females were found to have shorter AL ( p < 0.0001), shallower ACD ( p < 0.0001) and steeper corneas ( p < 0.0001). In both genders, AL, ACD and with the rule astigmatism showed a decreasing trend ( p = 0.0001), while keratometry, the average cylinder, and against the rule astigmatism showed an increasing trend ( p = 0.0001) with increasing age. Furthermore, in both genders, there was an increasing trend in ACD ( p = 0.0001), and a decreasing trend in keratometry ( p = 0.0001) and LT ( p = 0.0001) with increasing AL. Conclusions. This study provides useful reference data on ocular biometry for cataract surgeons in Bosnia and Herzegovina. Female patients tend to have steeper corneas, shorter AL and shallower AC than males, and these differences are independent of age or AL.

This study aims to thoroughly investigate the axial power peaking factors (PPF) within the low-enriched uranium (LEU) core of the Ghana Research Reactor-1 (GHARR-1). This study uses advanced simulation tools, like the MCNPX code for analysing neutron behavior and the PARET/ANL code for understanding power variations, to get a clearer picture of the reactor's performance. The analysis covers the initial six years of GHARR-1's operation and includes projections for its whole 60-year lifespan. We closely observed the patterns of both the highest and average PPFs at 21 axial nodes, with measurements taken every ten years. The findings of this study reveal important patterns in power distribution within the core, which are essential for improving the safety regulations and fuel management techniques of the reactor. We provide a meticulous approach, extensive data, and an analysis of the findings, highlighting the significance of continuous monitoring and analysis for proactive management of nuclear reactors. The findings of this study not only enhance our comprehension of nuclear reactor safety but also carry significant ramifications for sustainable energy progress in Ghana and the wider global context. Nuclear engineering is essential in tackling global concerns, such as the demand for clean and dependable energy sources. Research on optimising nuclear reactors, particularly in terms of safety and efficiency, is crucial for the ongoing advancement and acceptance of nuclear energy.
