Changes In Growth Rate Research Articles

Assessment of forest crops created on the dependent lands of Rivne region

The article presents the amount of work on afforestation in the Rivne region over the past 5 years. The forestry and taxation indicators, the composition and condition of forest plantations created on the ancestral lands have been determined. A comparative assessment of the change in the stock of common pine crops depending on the age and types of forest growing conditions in height and the actual and potential stock at a fullness of 1.0 is carried out. According to the research results, the change in the average growth rate of pure Scots pine crops was determined under conditions A2 and B 2. The distribution of plantations in childbirth according to the degree of damage by root sponges and insect pests was carried out, the scale and harmfulness of these lesions were determined. Analysis of information on the stock of wood of pine crops indicates that more intensive growth is observed in 55-year-old plantations with some predominance in fresh subor conditions. The dependence of the phytosanitary state of plantations on the type of forest growing conditions and their composition was revealed. The most resistant are plantations that grow in conditions C 2 and D2. Healthy plantings, without signs of damage by pathogens and insect pests, occupy an area of 51.1 %. In the overwhelming majority, clean pine plantations were affected. The main reason for the decrease in their resistance is the root sponge. The extent of the spread of root rot is explained by the degree of degradation and low fertility of soils, which are transferred for afforestation, which is directly related to the nature of their use. Plantations characterized by a high degree of root sponge infestation account for 1.2 %. It was found that the proportion of healthy plantations increases by 15–18 % with the participation of deciduous species in the composition of the tree stand. The research results can be used to select the optimal options for the initial composition of plantations for various types of forest growing conditions. Key words: afforestation, forest plantations, fallows, self-seeded forests, agricultural lands, Scots pine, reserve lands.

Resolution of the M-shape Pattern of the Outdoor Air Temperature Environmental Kuznets Curve (EKC) for Metropolitan Areas in a Country: Using Long-term Monthly Level Data of Taipei City as Empirical Evidence

In Taiwan, the heat island effect is the most significant in Taipei City. Thus this research provides a causal explanation for why urban outdoor air temperature has an M-shape EKC pattern for metropolitan areas in a country. Results show that the growth rate change in CO2 concentration can induce changes to the periods of the La Nino effect and EI Nino effect, causing high fluctuations in rain accumulation. The amount of rain then alters A-type evaporation, and so the evaporation amount is the top factor for the diffusion of a city’s heat. This fluctuation plays as a cooling and heating source for the V region of the M shape in the outdoor air temperature EKC pattern. In our previous studies, the growth rate change in CO2 concentration correlates to the energy structure. Therefore, a heat sinking model has been proposed to explain the accumulation of heat in a city, in which a proportion process for the solar irradiation source from buildings and remodeling engineering from a public housing policy and the private sector can play as a heating source of the two peaks of the M shape and present long-term linear growth in the outdoor air temperature EKC pattern.

Contemporary management and natural history of aberrant right subclavian artery

ObjectiveAn aberrant right subclavian artery (ARSA) is the most common congenital anomaly of the aortic arch. A paucity of reported studies is available regarding the treatment of these patients. The purpose of the present study was to evaluate the contemporary management strategies and natural history of ARSA in these patients. MethodsA single-center retrospective review of patients with a diagnosis of ARSA from 2009 to 2019 was performed. Computed tomography scans were analyzed, and the aortic and ARSA diameters were measured at 10 different segments. The demographic data, comorbidities, and operative interventions were collected. The patients were categorized into those who had undergone intervention and those who had undergone expectant management. Linear mixed effect models were used to estimate the annual ARSA diameter changes. ResultsA total of 30 patients with ARSA were identified, 17 (57%) of whom were women. The average age for the cohort was 54.5 ± 14.6 years. Of the 30 patients, 20 (67%) had undergone operative repair at presentation and 10 (33%) were initially observed. The most common presenting symptom was dysphagia (30%). Of the 10 patients who had been initially treated expectantly, 4 had subsequently required intervention. Of the 24 operative interventions, 13 (54%) were hybrid procedures involving right carotid–subclavian bypass or transposition and thoracic endovascular aortic repair. The mean diameter of ARSA at its origin was 20.4 ± 5.7 mm, and the mean cross-sectional aortic diameter at the level of the ARSA was 31.8 ± 8.5 mm for the entire cohort. For the patients who had initially been observed and had subsequently required intervention, the largest change in the ARSA cross-sectional diameter was observed 1 cm distally to the vessel ostium at a rate of 3.05 mm annually (95% confidence interval, 1.54-4.56; P < .001). No statistically significant changes in the annual growth rate of the aortic segments were observed in the entire cohort or for those patients who had undergone intervention (P > .05). ConclusionsThe decision to intervene on an ARSA should be individualized by the presence of symptoms (eg, dysphagia lusoria) or complications (eg, dissection, concomitant aortic aneurysmal disease, enlarging Kommerell diverticulum). Asymptomatic patients with nonaneurysmal ARSA might not require any intervention and can be safely observed. Measurement of the cross-sectional ARSA diameter 1 cm distally to the ostium of the vessel might aid in the surveillance of vessel diameter changes. Additional studies are required to determine the specific size criteria as an indication for operative repair of asymptomatic Kommerell diverticulum.

Simulation of pellet ELM triggering in low-collisionality, ITER-like discharges

3D nonlinear, as well as 2D linear M3D-C1 simulations are used to model ELM triggering by small pellets in DIII-D discharges in the ITER relevant, peeling-limited pedestal stability regime. A critical pellet size threshold is found in both experiment and modeling depending on pedestal conditions, pellet velocity and injection direction. Using radial injection at the outboard midplane, the threshold is determined by M3D-C1 for multiple time slices of a DIII-D low-collisionality discharge that has pellet ELM triggering. Experimental observations show that a larger pellet size than the standard 1.3 mm diameter is necessary for ELM triggering; 1.8 mm pellets triggered several ELMs in cases where a smaller pellet failed. The M3D-C1 simulations are in good agreement with these observations. While the 2D linear simulations give insight into the change of growth rates for various toroidal modes with pellet size, the 3D nonlinear simulations apply a pellet ablation model that mimics the actual injection with good match to the experiment. The 3D nonlinear simulation confirms the pellet ELM triggering for a pellet size larger than the threshold found by the linear simulations.

Effect of dietary supplementation of astaxanthin (potent antioxidant) on growth rate, DMI, FCR and metabolic changes in Karan Fries heifers during heat stress

A study was conducted on twelve Karan Fries (Holstein Friesian X Tharparkar) heifers, (10-12 months), in LRC of NDRI, Karnal.Heifers were divided equally into two groups i.e. control, and treatment (supplemented with astaxanthin@ 0.25 mg per kgBW per day per animal) to assess the heat stress ameliorative action of astaxanthin during summer season. During experimental period, environmental variables were recorded and THI was calculated to assess levels of summer stress. Blood samples were collected from both the group of heifers at fortnightly interval for quantification of plasma leptin and ghrelin hormones.Body weights of heifers were recorded at monthly interval. The body weight gain and ADG were significantly (P  0.05) higher in treatment group. Feed intake was higher (P  0.05) and FCR was lower (P  0.05) in astaxanthin supplemented group.Plasma leptin was higher(P  0.05), while,plasma ghrelinand surface skin temperature were numerically lower in treatment than control group of heifers.The study found that astaxanthin supplementation amelio rated the negative impact of summer stress and helped in enhancement of growth rate and ADG by improving the feed intake and by decreasing the FCR of heifers.

Consumer Choice in Residential Mortgage Market: An Islamic Mortgage Contract

This paper examines the Islamic mortgage contract of Diminishing Musharakah and its impact on consumer welfare, house purchase, and mortgage payments. We build both static and dynamic models to study a homeowner’s decision-making. We pay special attention to expectation formations and simulate the model to analyze both Islamic and Conventional mortgage holders’ responses to changes in income growth, house prices, and interest rates. Estimates of the model, using housing data set of U.S. economy (1990–2018), indicate that Diminishing Musharakah contract holders achieve 2.5 to 4% higher discounted utility under constant and declining learning expectations. The reducing balance feature of the Diminishing Musharakah contract provides relative protection to a consumer from adverse income shocks and high-interest rate environments. Simulation results suggest that under dynamic conditions, the Diminishing Mushrakah provides 3.4% lower mortgage cost per housing unit. It prevents consumers of average and low-risk appetite from relatively riskier housing decisions. We learn that consumer chooses a 2.5% smaller house size under Diminishing Musharakah. The model also examines consumers with vector autoregressive (VAR) based expectations. We find that homeowners with optimistic forecasts may achieve a higher utility in a conventional mortgage.

Picoplankton Diel Variability and Estimated Growth Rates in Epipelagic and Mesopelagic Waters of the Central Red Sea

The diel variability of the abundance and cell size of picoplanktonic groups in the central Red Sea was monitored every 2 h in situ on 4 occasions (once per season) from 2015 to 2016. We distinguished Prochlorococcus, low (LF-Syn) and high (HF-Syn) fluorescence Synechococcus, small (Speuk) and large (Lpeuk) picoeukaryotes and two groups of heterotrophic prokaryotes of low (LNA) and high (HNA) nucleic acid content. The diel variability in abundance was less marked than in cell size and more apparent in autotrophs than heterotrophs. Specific growth rates were estimated by an empirical relationship from measurements obtained in bottle incubations of surface and deep samples collected in the winter compared with in situ variations in cell size over 24 h. Autotrophic picoplankton groups generally grew faster (0.23–0.77 d–1) than heterotrophic prokaryotes (0.12–0.50 d–1). Surface to 100 m depth-weighted specific growth rates displayed a clear seasonal pattern for Prochlorococcus, with maxima in winter (0.77 ± 0.07 d–1) and minima in fall (0.52 ± 0.07 d–1). The two groups of Synechococcus peaked in spring, with slightly higher growth rates of LF-Syn (0.57 ± 0.04 d–1) than HF-Syn (0.43 ± 0.04 d–1). Speuk and Lpeuk showed different seasonal patterns, with lower values of the former (0.27 ± 0.02 and 0.37 ± 0.04 d–1, respectively). HNA consistently outgrew LNA heterotrophic prokaryotes, with a higher growth in the epipelagic (0–200 m, 0.36 ± 0.03 d–1) than in the mesopelagic (200–700 m, 0.26 ± 0.03 d–1), while no differences were found for LNA cells (0.19 ± 0.03 d–1 and 0.17 ± 0.02 d–1, respectively). With all data pooled, the mean diel abundances of autotrophic picoplankton in the upper epipelagic and of HNA cells in the epipelagic and mesopelagic layers were significantly correlated with the specific growth rates estimated from cell size variations. Our high-resolution sampling dataset suggests that changes in growth rates underlie the noticeable seasonality of picoplankton recently described in these tropical waters.

Differential habitat use and recruitment facilitate coexistence in a community with intraguild predation.

Theory predicts that species engaged in intraguild predation (IGP) can only coexist under limited conditions, yet IGP is common in nature. Habitat complexity can promote coexistence by reducing encounter rates, but little information is known about the contribution of differential habitat use. We hypothesized that differential use of alternative habitats promotes coexistence of an intraguild (IG) predator and prey. We evaluated predictions of this hypothesis with an experimental introduction of an IG predator fish into four natural stream communities that previously contained only the IG prey fish. We monitored the development of this IGP over the course of four years to determine how each species used alternative stream habitats. The introduced species preferred pool habitats while the resident species was more evenly distributed across pools and riffles. The density of the resident decreased in the pool habitat preferred by the invader, accompanied by a local increase in the mean of the resident size distribution. Selective predation by the invader on hatchling residents appears to impact the residents' demographic response. The continued recruitment of resident juveniles in riffles, where the introduced species is rare, facilitated the persistence of the resident. This differential use of habitats was not accompanied by a change in the resident's growth rates in either habitat. Our results showed that differential habitat selection and recruitment promoted persistence during an invasion involving IGP, which helps to bridge the gap between theory and observation in explaining coexistence in IGP systems.

The root meristem is shaped by brassinosteroid control of cell geometry

Growth extent and direction determine cell and whole-organ architecture. How they are spatio-temporally modulated to control size and shape is not well known. Here we tackled this question by studying the effect of brassinosteroid (BR) signalling on the structure of the root meristem. Quantification of the three-dimensional geometry of thousands of individual meristematic cells across different tissue types showed that the modulation of BR signalling yields distinct changes in growth rate and anisotropy, which affects the time that cells spend in the meristem and has a strong impact on the final root form. By contrast, the hormone effect on cell volume was minor, establishing cell volume as invariant to the effect of BR. Thus, BR has the highest effect on cell shape and growth anisotropy, regulating the overall longitudinal and radial growth of the meristem, while maintaining a coherent distribution of cell sizes. Moving from single-cell quantification to the whole organ, we developed a computational model of radial growth. The simulation demonstrates how differential BR-regulated growth between the inner and outer tissues shapes the meristem and thus explains the non-intuitive outcomes of tissue-specific perturbation of BR signalling. The combined experimental data and simulation suggest that the inner and outer tissues have distinct but coordinated roles in growth regulation.

Effect of concentration of cadmium sulfate solution on structural, optical and electric properties of Cd1–x Zn x S thin films

Cd1– x Zn x S thin films were deposited by chemical bath deposition (CBD) on the glass substrate to study the influence of cadmium sulfate concentration on the structural characteristics of the thin film. The SEM results show that the thin film surfaces under the cadmium sulfate concentration of 0.005 M exhibit better compactness and uniformity. The distribution diagrams of thin film elements illustrate the film growth rate changes on the trend of the increase, decrease, and increase with the increase of cadmium sulfate concentration. XRD studies exhibit the crystal structure of the film is the hexagonal phase, and there are obvious diffraction peaks and better crystallinity when the concentration is 0.005 M. Spectrophotometer test results demonstrate that the relationship between zinc content x and optical band gap value E g can be expressed by the equation E g(x) = 0.59x 2 + 0.69x + 2.43. Increasing the zinc content can increase the optical band gap, and the absorbance of the thin film can be improved by decreasing the cadmium sulfate concentration, however, all of them have good transmittance. At a concentration of 0.005 M, the thin film has good absorbance in the 300–800 nm range, 80% transmittance, and band gap value of 3.24 eV, which is suitable for use as a buffer layer for solar cells.

Cyclic Crack Growth in Chemically Tailored Isotropic Austenitic Steel Processed by Electron Beam Powder Bed Fusion.

The present study analyzes the cyclic crack propagation behavior in an austenitic steel processed by electron beam powder bed fusion (PBF-EB). The threshold value of crack growth as well as the crack growth behavior in the Paris regime were studied. In contrast to other austenitic steels, the building direction during PBF-EB did not affect the crack propagation rate, i.e., the crack growth rates perpendicular and parallel to the building direction were similar due to the isotropic microstructure characterized by equiaxed grains. Furthermore, the influence of significantly different building parameters was studied and, thereby, different energy inputs causing locally varying manganese content. Crack growth behavior was not affected by these changes. Even a compositional gradation within the same specimen, i.e., crack growth through an interface of areas with high and areas with low manganese content, did not lead to a significant change of the crack growth rate. Thus, the steel studied is characterized by a quite robust cyclic crack growth behavior independent from building direction and hardly affected by typical parameter deviations in the PBF-EB process.

IMPACT OF TEMPERATURE CHANGE ON GROWTH OF LABEO ROHITA: DEVELOPMENT OF A GROWTH MODEL

Enhanced temperature is one of the most important drivers of climate change as evidenced by a perceptible rise of air and water temperature in various regions of India. Unit rise in water temperature affect the physiological features of freshwater fish in aquaculture. Investigations were conducted to assess the impact of increasing water temperature of 29 oC, 30 oC, 31 oC, 32 oC, 33 oC, 34 oC and 35 oC on the growth, Labeo rohita fingerlings reared for five weeks in aquarium. The fishes were fed pelletised feed ad libitum. Fish reared at 34 oC water temperature exhibited significantly (P<0.05) faster growth (SGR-2.36 % body weight per day) than those reared at other temperatures. The change in growth rates were insignificant between 29 oC, 30 oC, 31 oC and 32 oC treatment groups but growth rates significantly increased in the temperatures ranging from 32 oC to 34 oC and there after it decreased. A linear growth model of L. rohita fingerlings growth has been developed using the data generated. This simple growth model provided a reliable projection of growth (SGR %) with unit rise of temperature within the range of 29 o to 34 oC. This will help fish culturists to develop adaptation strategies with regard to suitability of fish species and fish culture practices under the climate warming scenarios.

Thermocapillary effect on the dynamics of falling self-rewetting fluid films down a heated vertical cylinder

Nonlinear dynamic analysis of a self-rewetting fluid (SRWF) film flowing down the surface of a vertical cylinder is performed in this paper. The effect of the Biot number, Marangoni number and the substrate curvature on the interfacial evolution patterns and flow stabilities are discussed by linear stability analysis and numerical simulations of the evolution equation of the film thickness. Starting from the characteristic temperature T0 relating to the minimum surface tension and the interfacial temperature Ti, the nonlinear dynamics of the liquid film is investigated numerically in the cases of either Ti>T0 or Ti<T0. Good agreement of linear stability analysis with numerical simulations proves that the LSA could predict the development of thin liquid film flows in the early-time evolution. Through the analysis, we demonstrate that the Marangoni number Ma and the Biot number Bi play contrary roles for the two cases. For Ti<T0, the fingering instability is enhanced by the Marangoni effect while the inverse Marangoni effect stabilizes the interface for Ti>T0. The growth rate changes linearly with the increase of Marangoni number while it changes in forms of arched shapes versus lg(Bi). The growth rate reaches a maximum/minimum value at Bi=1, corresponding to the most/least unstable state. The radius of the cylinder R plays a significant role in the long wavelength modes, showing a stabilizing effect. For perturbations of short waves, increment of R expands the instability region. Nonlinear oscillatory waves (Rayleigh–Plateau instability) appears when the radius is smaller than 1 and fingering pattern tends to occur if the cylinder has a large radius (R≥1).

Altered growth conditions more than reforestation counteracted forest biomass carbon emissions 1990\u20132020

Understanding the carbon (C) balance in global forest is key for climate-change mitigation. However, land use and environmental drivers affecting global forest C fluxes remain poorly quantified. Here we show, following a counterfactual modelling approach based on global Forest Resource Assessments, that in 1990–2020 deforestation is the main driver of forest C emissions, partly counteracted by increased forest growth rates under altered conditions: In the hypothetical absence of changes in forest (i) area, (ii) harvest or (iii) burnt area, global forest biomass would reverse from an actual cumulative net C source of c. 0.74 GtC to a net C sink of 26.9, 4.9 and 0.63 GtC, respectively. In contrast, (iv) without growth rate changes, cumulative emissions would be 7.4 GtC, i.e., 10 times higher. Because this sink function may be discontinued in the future due to climate-change, ending deforestation and lowering wood harvest emerge here as key climate-change mitigation strategies.

PSIX-29 Study of the association of mtDNA haplogroups and Ages of 100 days in pigs

Abstract The aim of the work was to determine the mtDNA haplogroups and assess their associations with Days_100 in pigs based on sequencing the D-loop region. The research was carried out on Landrace sows (n = 123). To amplification a fragment of mtDNA D-loop conducted PCR using the following primers: F5 ‘ - TGC AAA CCA AAA CGC CAA GT-3’ and R: 3 ‘ - TTT TTG GGG TTT GGC AAG GC-5. Statistical analyzes were performed using Linear mixed model fit by REML (‘lmerModLmerTest’). The studied group of pigs had the largest number of D haplogroups, which were definitely in 66 sows (53.7%). Haplogroup E was identified in 18 sows (14.6%). Among the haplogroups of Asian origin, which include A, B and C, only genotype C was present. Statistical differences for D100 were established between Hap_C and Hap_E. The presented results indicate the influence of mtDNA haplogroups on Days_100 and pigs of hapogroup E showed the best results compared to analogs of haplogroup E. This may be due to the fact that haplotype E is of European origin, and haplotype C is of Asian origin. Breeding commercial European pigs is focused on increasing the growth rate, and this significantly reduces pig keeping costs and increases production efficiency. It should be noted that changes in growth rate are associated with more intense metabolic processes where mitochondria play a significant role. This may be reflected at the genetic level being determined by the nucleotide sequence of mtDNAs and at the haplotype level in particular. This research was funded by Ministry of Science and Higher Education of the Russian Federation (0445-2021-0008).

Fiscal Economic Instruments for the Sustainable Management of Natural Resources in Coastal Marine Areas of the Yucatan Peninsula

Fiscal economic instruments (FEI) are indirect regulation mechanisms that generate public revenue for the state through rights to use, charges, and concessions. In Mexico, some of these instruments can be used in the surveillance, administration, and preservation of the environment. In this paper, we analyze the changes in Federal and State growth rates of expenditure budgets in critical areas of the Yucatan Peninsula coast to describe their contribution to sustainable development during the last 12 years. We present an adaptation of the methodological guide of economic instruments for environmental management from CEPAL, with 2013 as the base year for the Gross Domestic Product (GDP) deflator and the use of the Protocol of Nagoya year as an international compromise signed by Mexico. The results obtained show that the expenditure budgets respond to economic, political, and short-term security attention without expectations for sustainability. However, alarming evidence of severe environmental deterioration in the coast is diminishing natural attraction, from tourism, for example, which is the main source of income in the region. The effective use of FEI by local governments may be useful to addressing environmental challenges from a decentralization process with better awareness of the importance of coastal areas for regional sustainability.

Commercial Energy Demand Forecasting in Bangladesh

Although both aggregate and per capita energy consumption in Bangladesh is increasing rapidly, its per capita consumption is still one of the lowest in the world. Bangladesh gradually shifted from petroleum-based energy to domestically sourced natural-gas-based energy sources, which are predicted to run out within next two decades. The present study first identified the determinants of aggregate commercial energy and its three major components of oil, natural gas, and coal demand for Bangladesh using a simultaneous equations framework on an annual database covering a period of 47 years (1972–2018). Next, the study forecast future demand for aggregate commercial energy and its three major components for the period of 2019–2038 under the business-as-usual and ongoing COVID-19 pandemic scenarios with some assumptions. As part of a sensitivity analysis, based on past trends, we also hypothesized four alternative GDP and population growth scenarios and forecast corresponding changes in total energy demand forecast. The results revealed that while GDP and lagged energy demand are the major drivers of energy demand in the country, we did not see strong effects of own- and cross-price elasticities of energy sources, which we attributed to three reasons: subsidized low energy prices, time and cost required to switch between different energy-mix technologies, and suppressed energy demand. The aggregate energy demand is expected to increase by 400% by the end of the forecasting period in 2038 from its existing level in 2018 under the business-as-usual scenario, whereas the effect of COVID-19 could suppress it down to 300%. Under the business-as-usual scenario, the highest increase will occur for coal (3.94-fold), followed by gas (2.64-fold) and oil (2.37-fold). The COVID-19 pandemic will suppress the future demand of all energy sources at variable rates. The ex ante forecasting errors were small, varying within the range of 3.6–3.7% of forecast values. Sensitivity analysis of changes in GDP and population growth rates showed that forecast total energy demand will increase gradually from 3.58% in 2019 to 8.79% by 2038 from original forecast values. Policy recommendations include capacity building of commercial energy sources while ensuring the safety and sustainability of newly proposed coal and nuclear power installations, removing inefficiency of production and distribution of energy and its services, shifting towards renewable and green energy sources (e.g., solar power), and redesigning subsidy policies with market-based approaches.

Sex Differences in Rate of Axial Elongation and OcularBiometrics in Elementary School Students.

PurposeTo determine the relationship between the ocular biometrics and axial length (AL) elongation and its rate in elementary school children.MethodsThis is a prospective observational study of 102 right eyes of third-grade elementary school students who were 8 to 9 years old. All participants underwent measurements of the AL, anterior chamber depth (ACD), and lens thickness (LT) annually for 3 years. The AL elongation during the first half and second half was calculated by subtracting the AL of the 1st year from that at the 2nd year, and AL of the 3rd year minus 2nd year. The total AL elongation (TALE) was obtained by summing up the first and second half AL elongations. The growth rate change (GRC) was obtained by subtracting the first half AL elongation from second half AL elongation. Spearman correlations were used to determine the correlation between the 1st year ocular biometrics and the TALE and GRC.ResultsThe mean TALE was 0.54 ± 0.26 mm in boys and 0.46 ± 0.31 mm in girls. The mean GRC was 0.00 ± 0.16 mm in boys and −0.04 ± 0.14 mm in girls. In boys and girls, the TALE was significantly larger in the eyes with myopic ocular biometrics such as a deeper ACD, thinner LT, and longer AL during the 1st year (|r|=0.41 to 0.46, P < 0.05). The GRC was significantly accelerated in the eyes of only the girls with hyperopic ocular biometrics such as a shallower ACD, thicker LT, and shorter AL during the 1st year (|r|=0.31 to 0.41, P<0.05).ConclusionIn boys and girls, the TALE tends to be larger in eyes with myopic biometrics at the 1st year examination. The GRC tended to accelerate in the eyes with hyperopic ocular biometry during the 1st year only in girls.
