Результаты оценки периферического зрения на синий цвет у детей

Purpose. To evaluate changes in peripheral vision for blue color in children. Material and methods. This study involved 100 patients (200 eyes) aged 7 to 17 years. Patients underwent a comprehensive diagnostic examination. Results. The average BCVA value was 0.9 (0.8–1.0), anterior-posterior size of the eye (APS) – 24.3 (23.2–25.2) mm, total visual field for white color – 520 (497–520) with a norm of 530, and the average value of total visual field for blue color is 409 (373–432) with a norm of 380. A weak inverse correlation was established between the value of total visual field for blue color and the value of APS (r= –0.16 at p<0.05). A narrowing of visual field of more than 15 degrees for white color was detected in 55 cases. A narrowing of visual field for blue color was detected in 56 cases, with a narrowing of more than 15 degrees – in 35 cases. When assessing BCVA in patients with clinically significant narrowing of the visual field for blue color, it was revealed that in 5 cases the BCVA was 0.4–0.7, in 5 cases the BCVA was less than 0.4. A biometric study of the eye in patients with a clinically significant narrowing of the visual field for blue color showed that in 2 cases there was APS of 16.47 mm (one child in both eyes), in 6 cases APS was up to 24 mm, in the remaining 28 cases APS was more than 24 mm (24.16–26.62 mm). Conclusion. Assessing peripheral vision for blue color has clinical significance in patients diagnosed with amblyopia, that requires more detailed assessment in this group of patients. Key words: visual field for blue color, perimetry for colors, amblyopia, children’s vision, peripheral vision, perimetry

Evolution of the Late Cretaceous orbitoidal foraminifera and implications for the taxonomy and biostratigraphy in the Eastern Neo-Tethys, Lower Indus Basin, Pakistan: A biometric approach

In the eastern Neo-Tethys realm, the Late Cretaceous larger benthic foraminifera (LBF) Orbitoides and Omphalocyclus are poorly known. Herein, Orbitoides and Omphalocyclus populations from the Fort Munro Formation in Rakhi Nala Section, Lower Indus Basin, Pakistan are investigated. This work documents the most primitive evolutionary stages of these genera in the eastern Neo-Tethys. In Orbitoides, the average values of the size of embryon (Li + li) for the 18 investigated samples range between 477 and 516 µm and the average E values range between 4.2 and 4.7. In Omphalocyclus, the embryons are always trilocular and their sizes range between 112 and 485 μm, with an average between 153 and 287 μm. The E values range between 2 and 3, with an average of 2.3. Based on the average values of E and size of the embryon (Li + li), the populations of Orbitoides and Omphalocyclus have been attributed to the O. media and O. omanensis species, respectively. A late Campanian age is assigned to the Fort Munro Formation based on the recognition of O. media and O. omanensis. The detailed biometric study reveals primitive species of Orbitoides and Omphalocyclus from Pakistan (a part of eastern Neo-Tethys) in the Asian biogeographic province (ASP) during the late Campanian.

A MORPHOLOGICAL OBSERVATION OF THE TONGUE OF AN ADULT QUWA LOCAL DOMESTIC DUCK (Anas platyrhynchos domestica)

A Biometric study was conducted on the tongue of twenty-five (25) adult domestic duck of both sex collected from the Sokoto metropolitan poultry and fish modern market, over a period of seven days. A pair of scissors, a scalpel and a blade was used to incise, excise, separate or debride various parts of the oral cavity to expose the organ for morphological observations. Results showed that the tongue is characterized by an elongated triangular format. At a point, approximately 2/3 the length of the lingual corpus there is a distinct depression, separating the caudal one-third of the lingual corpus from its rostral two-third. On the dorsal surface of the apex and body of the tongue, a median groove was present. A unique feature observed on the tongue in domestic Duck is the presence of many fine overlapping needle- shaped processes at both lateral sides of the caudal lingual-apex. A single row of large conical papillae is observed symmetrically in the marginal region between the body and root of the tongue. Biometrically the mean dimensions were discussed clearly. Based on the findings, there is need to conduct a research in detail to study the histological features and differentiation at specific ages of ducks, in order to relate this features with their special adaptive mode of feeding.

Biometric Characteristic Study of Green Lipped Mussel, Perna viridis (Linnaeus, 1758) From Malad Creek, Mumbai, India

Biometric Studies are essential to understand the growth rate of the species which helps understand the growth patterns, reproduction rate and population distribution of the species. Growth patterns of molluscs help in evaluating their production potential and energy flows through populations and their distribution. Perna viridis (Linnaeus, 1758) commonly known as the green-lipped mussel or the Asian green mussel belongs to the family Mytilidae. It is distributed along the Indo-Pacific region. They are attached to the rocky substratum along the coast, in the intertidal region. The Biometric Analysis and Length-Weight Relationship study was carried out on Perna viridis (Linnaeus, 1758) to understand their growth rate and population distribution through the Coast of Mumbai. A total of 100 samples were used in this study. The correlation between the Total Weight of the Shell with the organism (WSO) to the Shell Length (SL), Shell Width (SW) and Shell Height (SH) and the correlation between the Soft Tissue Weight of the Organism (WO) to the Shell Length (SL), Shell Width (SW) and Shell Height (SH) gave an idea about the growth factors. The Relative Condition Factor was determined by equation W = aLb. The b values of each correlation showed negative allometric growth with p value to be p<.001 with same significance in Pearson Correlation test. The Relative Condition Factor of WSO-SW and WSO-SL was observed to be above 1 indicating good growth conditions. Thus, biometric studies are a useful tool in study of Perna viridis (Linnaeus 1758) biology, physiology, ecology, growth potential, stock assessment, genetics and breeding of Perna viridis (Linnaeus, 1758).

Ultrasound Morphometry of the Pelvic Floor Muscles in Women of Reproductive Age

Biometric studies in nulliparous women conducted to date are limited by small sample sizes. The pelvic floor muscles perform an important function throughout a woman’s life. They provide fixation and maintenance of the pelvic organs, stretches during childbirth, ensuring the formation of the birth canal, and are a potential site for the formation of a hernia in the female body. Impaired function of this muscle group can lead to either excessive muscle contraction (chronic pelvic pain syndrome) or excessive stretching (pelvic organ prolapse). The purpose of the study is to assess the morphometric properties of the pelvic floor muscles in nulliparous women using 3D ultrasound scanning (sonography). Material and methods. The observation group consisted of 60 women of middle reproductive age who applied for an appointment with an obstetriciangynecologist with complaints of pain of various types localized in the perineum and pelvis, decreased desire and quality of sexual life, clinically confirmed by a diagnosis of incompetence of the pelvic floor muscles. The control group consisted of 30 women without dysfunction of the pelvic floor muscles according to clinical examination. The main criterion for inclusion of patients in the study was reproductive age - 18–45 years and natural childbirth in obstetric and gynecological history. Results. We found that the absence of visible sonographic markers of changes in the myofascial structures of the pelvis is not a prognostically significant criterion for muscle dysfunction, since predominantly changes in morphometric parameters are a reliable sign of the formation of pelvic floor muscle failure. Conclusion. The ultrasound morphometry method, which allows one to assess dynamic changes in the size of muscle and fascial structures, can be used in the clinical practice of an obstetrician-gynecologist. Early diagnosis of a violation of the structure of pelvis myofascial complex will allow early implementation of measures aimed at prevention and timely treatment.

Modeling the effect of fertilizers on cotton yields and cotton fiber quality on saline soils in so uthern Kazakhstan

Yntymak st.,26, Kazakhstan Cotton in Kazakhstan is one of the strategically important crops and is cultivated in the extreme south of the republic in the Turkestan region, in the northernmost cotton-growing zone on the globe. The aridity of the climate, the shortage of irrigation water and the growing threat of the risk of increasing saline lands in cotton plantations, on the one hand, and the insufficient and unjustified use of minerals, on the other, are the main limiting factors in cotton production. On the industrial plantations of the peasant farm "Sabyr", v. Atakent, Maktaaral district, Turkestan region, field experiments were carried out on serozems of slightly and moderately salinity in 2022. In experiments on two salinity backgrounds, 9 identical treatments of fertilizers with different doses and ratios of nitrogen, phosphorus and potassium were studied. During the phases of budding, flowering and fruit formation of cotton, biometric studies and selection of plant samples were carried out to study photosynthetic and yield indicators depending on fertilizers on 2 salinity backgrounds. The effect and interaction of fertilizers and the amount of salts in the soil on the formation of leaves in various phases of cotton development isquite accurately described (R2 = 0,957-0,972) by regression equations. At the same time, the effect of single action of nitrogen and potassium fertilizers was negative, and that of phosphorus fertilizers was positive. During the growing season, double combinations of all the studied factors, with the exception of nitrogen and potassium, had a negative effect on the dynamics of accumulation of cotton plant biomass. The gross cotton yield is 86% determined by the complex total influence of nitrogen, phosphorus and potassium fertilizers and the degree of soil salinity. At the same time, the unilateral effect of nitrogen and potassium fertilizers and soil salinity on cotton yield was negative, and that of phosphorus fertilizer was positive. There is a high correlation between potassium nutrition and fiber quality indicators (r = 0,38-0,62). Changes in fiber quality indicators generally had a strong relationship with the amount of salts in the topsoil (r = 0,51-0,61).

Taxonomic characterization, morphological variability, and geographic patterns of Juniperus turbinata Guss. in Algeria

A biometric study of cones, seeds, needles, and branchlets was conducted in 15 natural populations of Juniperus turbinata Guss. within its Algerian range. Each population was represented by 20-30 individuals. A total of 386 individuals were examined to evaluate inter- and intraspecific variation, and its geographic patterns, confirming the status of J. turbinata in Algerian populations. Maritime and mainland (Atlas Mountains) populations differed significantly. Cones in the seaside areas tended to be longer and more turbinate, with fewer seeds (mean 4.80) and leaves on the terminal 5-mm section of lateral branchlets (mean 27.87), compared to those from the Atlas, with 5.75 seeds and 29.00 leaves on average. The Aurès Mountain populations had more leaves than other scale-like junipers and other species of the Cupressaceae. Furthermore, maritime popula­tions stood out for having the most turbinated cones among recorded Juniperus phoenicea s.l. populations. Costal populations were more related to those located on oriental Mediterranean shores, while Atlas Mountain populations seemed to be related to Moroccan Atlas ones. A negative gradient of leaf number from east to west was identified in the Atlas group, extending into Morocco. The distinct separation between the 2 geographic patterns supports the hypothesis of migration of J. turbinata along 2 routes and relaunches the proposal of possible varieties within the group.

Length-Weight, Length-Length Relationships and Condition Factor of <i>Crossocheilus diplochilus</i> (Heckel) from Dal Lake of Kashmir Himalayas

Length-Length Relationships (LLRs) and Length-Weight Relationships (LWRs) are vital tools in the management of fisheries to facilitate a proper understanding of the condition of fish species and the growth pattern from different environments. Despite numerous studies on LWRs and LLRs of fish species, the majority of those have focused on the food fish creating a lacuna in the biometric assessment studies of forage fish. Against this backdrop, the current work was undertaken to estimate the LLRs, LWRs and condition factor of Crossocheilus diplochilus, a forage fish from Dal Lake of Kashmir Himalayas. The fish was reported to show negative allometric growth, attaining a maximum length of 14.8 cm and a maximum weight of 17.19 g. The overall condition factor was reported to be 0.86 ± 0.10, reflecting a poor condition of growth. The fish forms a vital trophic link of the lake, as such timely biometric studies could help in managing its stock properly.

Gökpınar Baraj Gölü (Batı Anadolu, Türkiye)’ndeki Egzotik Güneş Levreği Popülasyonunun (Lepomis gibbosus) Biyo-Ekolojik Özellikleri Üzerine Bir Araştırma

This study was conducted to determine some bioecological characteristics of Lepomis gibbosus (L. 1758), commonly known as pumpkinseed sunfish, which spreads in Gökpınar Dam Lake (GDL) in Denizli Province. The fish samples were captured with an experimental seine net and multimesh gillnet from May 2019 to April 2020. During the samplings, certain physicochemical parameters of GDL were measured, habitat utilization, relations to environmental variables, feeding habits and interspecific interactions with other fishes of L. gibbosus individuals were observed. It is observed that GDL provides a suitable habitat for L. gibbosus in terms of water quality and other ecological requirements. A total of 1005 L. gibbosus individuals, consisting of 302 females, 605 males, and 98 juveniles, were sampled throughout the study, and biometric studies were conducted. In the population males were found to be dominant. The averages were determined as follows; total length as 5.82±2.09 cm (2.46-11.34), weight as 4.94±4.67g (0.20- 34.65), and condition factor as 1.71±0.24. The ages were determined between 0+ to II+and Age-length relationship (VBGE) was estimated as L_(t=) 19,85(1-e^(-0,2744(t+0,272) ) ) Spawning occurs between April and June in individuals at the age of I+. It has been observed that the species exhibits good growth rates in this habitat, displays opportunistic omnivorous feeding behavior, preys on another invasive alien species, Gambusia holbrooki, present in the lake, and competes with the same species for habitat sharing. It has been determined that L. gibbosus has formed a self-sustaining population in GDL, but it utilizes a limited lake area as its habitat. In conclusion, GDL is considered as a hydrologically unstable and highly variable habitat. L. gibbosus population of GDL exhibits significant similarities in terms of bioecological characteristics with populations that spread outside its natural spreading area. As L.gibbosus is an exotic fish and might be have invasive traits, it is necessary to monitor of the population regularly, and control measures should be taken to prevent its spread to other inland water bodies.

Silaum silaus (L.) Schinz and Thell.—Habitat Conditions and Variation in Selected Characteristics of Populations at Different Densities

Grasslands are one of the most diverse and species-rich ecosystems in the agricultural landscape of Central Europe. However, they are gradually being overgrown or transformed into arable fields due to their abandonment and the intensification of economic activities. This leads to a drastic decline in biodiversity and the disappearance of many rare species, e.g., Silaum silaus. Research on Silaum silaus populations was conducted in the years 2020 and 2022. Data were obtained from two Natura 2000 sites. The Jaćmierz site is located in a dispersed range of Silaum silaus in south-eastern Poland. The site at Zagórzyce is located in a dense range of the species in the south-western part of the country. Research on the habitat conditions was conducted on two permanent study surfaces with the dimensions of 10 × 10 m. This research included a soil study and measurements of herbaceous vegetation. To determine the habitat conditions, use was also made of Ellenberg ecological indicator values. At each site, 10 phytosociological relevés were conducted with the Braun-Blanquet method. In each study year, the manner of land use was determined. For detailed population study, one permanent surface of the dimensions 10 × 10 m was marked out, on which each year the generative and vegetative specimens were counted and biometric studies were conducted on 30 randomly chosen generative specimens. The species occurred in two different meadow communities (Arrhenatheretum elatioris, Molinietum caeruleae), which were characterised by different habitat conditions, and the greatest differences were evident in the chemical properties of the soil and in the method of management. The meadows at Jaćmierz were mowed twice a year, while at Zagórzyce mowing was performed once every two years. The communities were also varied in terms of flora, characterised by a high species richness and a high Shannon–Wiener index. Silaum silaus had significantly greater numbers and an over four times higher cover coefficient at Jaćmierz. The largest differences in the analysed traits of the species occurred in the case of generative traits. It was observed that management practices at Jaćmierz had a strong influence on the condition of specimens and the population size of Silaum silaus, which was much better preserved at this site.

Pectin wrapped halloysite nanotube reinforced Polycaprolactone films for potential wound healing application

The current research work focuses on preparing the polycaprolactone (PCL) based nanocomposite films embedded with surface modified Halloysite Nanotube (HNT). The avenue of the study is to unravel the applicability of polymer nanocomposites for wound healing. The flexible property of HNT was taken as the major force to accomplish the addition of biopolymer pectin onto its surface. Functionalization of HNT with pectin has certainly enhanced its binding nature with the polymer. The PCL nanocomposite films were characterized by several promising techniques such as FTIR, XRD, DSC-TGA, FESEM, TEM, AFM, and mechanical properties were too examined along. When compared to the plane PCL film, the nanocomposite films manifested favorable results in terms of mechanical and chemical properties. Additionally, biometric studies such as in-vitro swelling, enzymatic degradation, and hemolysis performed on the films gave extremely good results. The haemolytic percentage recorded for the films exhibited a steady decrease with increasing amount of nanofillers. The MTT assay showed cell proliferation and its increase as the embedded HNT is more in the matrix. Wound closure study performed on NIH3T3 cell line with 1, 3 and 5wt% of films has given a strong proof for the involvement of polymer and HNT in the healing procedure.

A study of ear biometrics in autopsied cases at the Universiti Kebangsaan Malaysia Medical Centre

BackgroundThe ears have increasingly been recognized as one of the supportive tools in forensics, based on the identification of landmark variations of ear biometrics in living persons. However, no studies on the reliability of such comparisons have been done on the deceased.MethodsThe study aimed to investigate the correlation between ear biometrics and the age, sex, and stature of the deceased. The study was conducted on 181 deceased persons, aged between 18 and 70 years old on cases received by the Forensic Unit of Universiti Kebangsaan Malaysia Medical Centre. Documentation of age, sex, race, and height was recorded, and photographs of bilateral ears were taken. Measurements of twelve ear biometrics based on the Iannarelli method and ear length and ear width were taken from the photographs.ResultsResults showed that there was a significant difference between males and females in six ear biometrics. There was also a significant correlation between ear biometrics, that is, ear length and ear width with the age and height of an individual.ConclusionsIn brief, there exists a significant difference between males and females in ear biometrics with good correlations between ear biometrics and the height and age of an individual. Hence, the ear can be used for personal identification in the forensic field.

First data on morphometric parameters of the European conger eel (Conger conger, Linnaeus, 1758) in Béni-saf Bay (Western Algerian coasts)

A biometric study was conducted on a benthic fish of the family Congridae, the European conger eel (Conger conger Linnaeus, 1758), from the western coasts of Algeria, from Béni-Saf. This study was carried out due to the total absence of reliable and exploitable information concerning the morphometric characteristics of this fish along the Algerian coast. It was based on statistical processing of 18 morphometric variables measured on each sampled fish. the comparison between months using univariate ANOVA and multivariate MANOVA statistical tests showed significant differences in morphometric variables measured on the European conger eel (Conger conger). However, regarding the sex factor, no significant differences were observed between males and females.

A comparative analysis of multi-biometrics performance in human and action recognition using silhouette thermal-face and skeletal data

Biometrics is a field that has been given importance in recent years and has been extensively studied. Biometrics can use physical and behavioural differences that are unique to individuals to recognize and identify them. Today, biometric information is used in many areas such as computer vision systems, entrance systems, security and recognition.In this study, a new biometrics database containing silhouette, thermal face and skeletal data based on the distance between the joints was created to be used in behavioural and physical biometrics studies. The fact that many cameras were used in previous studies increases both the processing intensity and the material cost. This study aimed to both increase the recognition performance and reduce material costs by adding thermal face data in addition to soft and behavioural biometrics with the optimum camera. The presented data set was created in accordance with both motion recognition and person identification.Various data loss scenarios and multi-biometrics approaches based on data fusion have been tried on the created data sets and the results have been given comparatively. In addition, the correlation coefficient of the motion frames method to obtain energy images from silhouette data was tested on this dataset and yielded high-accuracy results for both motion and person recognition.

Biometrics, presents, futures: the imaginative politics of science–society orderings

Abstract Biometric technology encompasses a proliferating array of data forms, applications, and stakeholders but has raised numerous social and ethical concerns. This article examines contending perceptions of biometrics by developing a three-way framework of science–society orderings, drawn from social studies of biometrics and wider science studies literature. By analysing documentary sources and participant observation data through this framework, the article identifies a series of distinct normative interpretations or imaginaries of biometrics. It is argued that these imaginaries, described, respectively, as ‘public good’, ‘collective control’, and ‘societal risks’, project contending normative framings of science–society relations. These imaginaries were also however found to reflexively encompass perceived challenges, giving rise to practices that I term imaginative politics. These findings raise the need for science policy studies to consider the distinction between imagining and realizing in greater depth and to consider more profoundly the politics of science–society co-production.

Linear Morphometric Analysis of Auricular Measurements of a Nigerian Igbo population

The human ear (auricle) is an important body component in biometric studies and forensic identification. The purpose of this study was to evaluate linear auricular morphometric measurements of a Nigerian Igbo population. 300 participants (142 males to 158 females) of at least 16 years of age were randomly recruited from settlements in the South-Eastern states of Nigeria. The participants were made to sit in a Frankfort horizontal position and auricular measurements such as total ear height (TEH), ear width (EW), lobule height (LH) and lobule width (LW) were obtained using a digital vernier caliper (validated by calibrating to 0.01mm). The ear index (EI) and lobule index (LI) were calculated using the measurements. Data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS version 23.0). The following mean values were recorded for males: TEH [Right (R) = 47.01±6.30, Left (L) = 46.24±5.85], EW (R = 25.06±4.14, L = 24.68±4.32), LH (R = 13.92±2.61, L = 13.99±2.18), LW (R = 12.99±2.30, L = 13.30±1.94), EI (R = 53.47±7.23, L = 53.28±6.69) and LI (R = 95.17±18.12, L = 96.80±18.56); for females, TEH (R = 48.25±6.83, L = 48.25±6.24), EW (R = 25.19±3.93, L = 24.57±4.21), LH (R = 14.44±2.67, L = 14.89±2.55), LW (R = 13.37±2.26, L = 13.78±2.04), EI (R = 52.50±6.85, L = 50.93±7.05) and LI (R = 94.60±19.59, L = 94.30±16.63). Gender differences were highly significant regarding total ear height, lobular length and width, as well as the ear index of the left auricle. This study provides a baseline data for auricular morphometrics of adult Nigerian Igbos and could be used as an ergonomic guide towards the creation of hearing aids in the future and to solve possible forensic issues associated with identification of remains.
