Abstract:

Abstract: Varuna River is an important tributary of river Ganga. For the present study River Varuna has been chosen for the morphometric analysis and the demarcation of the basinal area of the river has been automatically done through Geospatial tool known as Arc Hydro. The study regarding the morphometry of the river lets us infer about the basin geometry, network system of the drainage and more of the river basin characteristics. Calculations of the morphometry will give us the quantitative description of the drainage system, which is an important aspect of the basins. This will describe the shape, slope, elongation, drainage density and many more important values to further incorporate water management processes in the varuna river basin. GIS tools will help us achieving morphometric analysis. With the help of morphometric analysis we are able to gain knowledge regarding the basin geomorphology and its responses to various hydrological processes.

Abstract:

Morphometric characters of fishes are measurable or metric characters. Morphometrics is a more or less interwoven set of large statistical procedures to analyze variability in the size and shape of organisms. Morphometrics and phylogenetics of a species are combined to utilize existing phylogeny which addresses hypotheses of shape change through evolutionary time. Morphometric differences among stocks of a species are recognized as important to evaluate population structure and form a basis to identify stocks. Advancements in morphometrics used powerful tools for testing and displaying differences in shape, isolated shape from size variation and identifying stocks of species with unique morphological characteristics enabling better management of the species. Traditional or standard morphometry has been improvised from time to time with advanced methods by technological advancements like geometric morphometrics, image analysis, principal component analysis, truss network analysis and multivariate analysis as well as many more to update knowledge and get more accurate information. These advanced methods have strengthened earlier technologies to improve upgrade fishery research throughout the globe. Doi: 10.28991/HEF-2020-01-03-05 Full Text: PDF

Abstract:

Multivariate morphometry was used to investigate the distinctness and interrelationships of six stocks of the common carp (Cyprinus carpio). A "size" component was clearly identified by multiple group principal component analysis. Canonical variate analysis computed only on the "shape" components showed that the stocks were morphometrically distinct and that the phenetic relationships based on allozymic and morphometric data are highly congruent. We therefore suggest that multivariate morphometrics could represent an appropriate and convenient tool to detect variation between strains in carp culture.

Abstract:

CONTEXT: Differential diagnosis of hyperplastic vs adenomatous lesions is of crucial importance on the daily practice of colonoscopy. OBJECTIVES: This study aimed at quantifying digital morphometric characteristics of colonoscopic images obtained with magnification and chromoscopy of three different types of colonic lesions: hyperplastic, adenomas and carcinomas, and the normal mucosa surrounding the lesions. METHODS: A total of 2,177 consecutive colonoscopies were analyzed and 105 images were chosen for analysis, divided into 37 hyperplastic lesions, 42 adenomas and 26 carcinomas. Specific digital morphometry was used, to measure the diameter and area of the pits from hyperplastic lesions, adenomatous and carcinomatous lesions, always comparing them with the normal mucosa surrounding pits. RESULTS: Different morphometric measures were performed via image analysis software to measure the mean pit opening diameters and their respective area. The mean pit opening diameters and corresponding area measurements were statistically significant for all groups of lesions examined. CONCLUSIONS: The morphometric characteristics of colonoscopy images allowing the observer to compare differences between hyperplastic and adenomatous polyps and colorectal carcinoma lesions. Digital morphometric studies are feasible like the present study shows. This can help the colonoscopist in clinical decisions. A software with morphometric measures can apply and will permit the digital morphometric analysis. The data generated from the application of software, can provide valuable points in differentiation of various lesions, guiding the conduct clinical, already during the endoscopic procedure. Morphometric analysis is more an instance of decision to the colonoscopist and it has important value not for being subjective, but for being objective, since it generates digits of its measures. In these aspects, and among different characteristics, the measure of the area showed to be the most important measure in the differential aspect. Different lesions have different patterns of morphometric measures and theses patterns can be obtained from the study of the characteristics in databases. The endoscopic removal of adenomatous polyps (polypectomy), or a more detailed study of the neoplastic lesions for helping the decision if endoscopic removal (mucosectomy) or surgical resection, and a conservative position in hyperplastic lesions, are proceedings that morphometrics, with another parameters, can help to decide.

Abstract:

The scope of this work is to carry out a morphometric analysis of Pluto’s impact craters. A global Pluto digital elevation model (DEM) with a resolution of 300 m/px, created from stereoscopic pairs obtained by the New Horizons Mission, was used to extract the morphometric data of craters. Pluto’s surface was divided according to different morphometric characteristics in order to analyze possible differences in the impact dynamics and modification rate in each region. A Python code was developed, within the QGIS 3× software environment, to automate the process of crater outlining and collection of morphometric data: diameter (D), depth (d), depth variation, slope of the inner wall (Sw), diameter of the base (Db), and the width of the wall (Ww). Data have been successfully obtained for 237 impact craters on five distinct terrains over the west side of Sputnik Planitia on Pluto. With the collected data, it was possible to observe that craters near the equator (areas 3 and 4) are deeper than craters above 35°N (areas 1 and 2). Craters on the western regions (areas 2 and 3) contain the lowest depth values for a given diameter. The transition diameter from simple to complex crater morphology was found to change throughout the areas of study. Craters within areas 1 and 4 exhibit a transition diameter (Dt) of approximately 10 km, while Dt for craters within areas 3 and 5 the transitions occurs at 15 km approximately. The presence of volatile ices in the north and north-west regions may be the reason for the difference of morphometry between these two terrains of Pluto. Two hypotheses are presented to explain these differences: (1) The presence of volatile ices can affect the formation of craters by making the target surface weaker and more susceptible to major changes (e.g., mass waste and collapse of the walls) during the formation process until its final stage; (2) The high concentration of volatiles can affect the depth of the craters by atmospheric decantation, considering that these elements undergo seasonal decantation and sublimation cycles.

Abstract:

The morphometric analysis of the watershed is important to support the development of environmental studies. With the advancement of geotechnologies, Digital Surface Models (MDS), extracted from satellite images and processed in a Geographic Information System environment, have been an important source of data forthe morphometric analysis of basins. This study characterizes watershed morphometry using different MDS. The Pirapozinho river basin was adopted as the object of study. The findings of this work reveal a low propensity to flood the basin under analysis. Also, we note that there may be variations in the morphometric parameters according to the MDS used, even though they are models of the same spatial resolution.

Abstract:

Abstract Morphometric analysis is a powerful tool to understand the hydrological process quantitatively and the main requirement to determine the hydrological characteristics of a watershed. Morphometric analysis to determine the drainage characteristics of the Sedayu River Sub-watershed, Semaka District, Tanggamus Regency, Lampung Province was carried out using Digital Elevation Model (DEM) data. The primary data used is aerial photography using drones, the location of aerial photos representing watersheds of concern. The catchment area morphometrics were obtained from the extraction of the morphometric characteristics of the combined DEM data from the mountain watershed and the analysis of topographic maps by using ArcGIS software. Based on reports over a period of time, at several points in the area there are frequent river floods that overflow during heavy rains. Morphometric analysis in flood-prone areas with high rainfall is needed. The morphology of the Sedayu area has contrasting variations consisting of several gentle alluvial plains, some of which are Bukit Barisan hills with varying slope variations. The Sedayu watershed in this study is divided into 3 sub-watersheds, namely: sub-watershed A, sub-watershed B, and sub-watershed C. However, only sub-watershed A is the focus of morphometric analysis because its longest river, record flood disasters, landslide records, and has upstream to residential. Morphometric analysis was carried out on parameters such as watershed area (A), watershed length (Lb), main river length (Ln ), watershed width (W), drainage density (Dd ), bifurcation ratio (Rb ), and circularity ratio (Rc ). The results of morphometric calculations are the length of the watershed 4.82 km, the length of the main river is Sub-watershed A 8.996 km, the width of the watershed 0.686 km, and watershed area 4.861 km2 Based on these results can be calculated drainage density (Dd ) 2.719 km/km2 which means Sub-watershed A of a rough type with the inundated surface, permeable sub-soil, and resistant to erosion. Bifurcation ratio (Rb ) is 3.333 which means sub-watershed A has a rapid rise and fall in floodwater. Then, the circularity Ratio (Rc ) 0.32 which means Sub-watershed A is elongated so that the peak discharge and decrease flow quickly and causes a link with the hydrological response of rainfall-runoff. The results of this morphometric characteristic analysis are the right reference for planning strategies for soil erosion control and soil conservation.

Abstract:

Abstract Background Total knee arthroplasty and unicompartmental knee arthroplasty are frequently done procedures for the treatment of various forms of arthritis and knee injuries. The knee prosthesis, which is used for these procedures, requires adequate sizing specific to the population. Morphometric parameters of upper end of the tibia can be used to guide treatment and monitor outcome of total knee replacement surgeries. Information regarding morphometry of upper end of the tibia is important as it provides reliable method of assessing knee deformity. This article assesses different morphometric parameters of condylar and intercondylar surface of the tibia and to compile the results, analyze, and formulate a baseline data for future studies with relevance to Indian population. Materials and Methods The study group comprised of 60 adult human dry and processed tibia of both sides which are grossly normal and complete, obtained from the Department of Anatomy, Himalayan Institute of Medical Sciences. Morphometric measurements of the medial condyle, lateral condyle, and intercondylar area of tibia were recorded with vernier calipers with a least count of 0.01 mm. The dimensions were summarized as mean ± standard deviation. A p-value of < 0.05 was considered significant. Result Mediolateral and anteroposterior length were 66.33 and 42.52 mm, respectively. Conclusion Anatomical profile of tibial condyle for Indians is smaller, hence highlighting the need for sizing of prosthesis specific to the population in question.

Abstract:

Water flows with significant flow rate feature a high destructive force and can lead to catastrophic consequences. Fluvial processes caused by uneven distribution of rain precipitation over the area pose risks to the developed inland foothill territories. The purpose of this study is to carry out a quantitative morphometric analysis of the territory in order to identify the formation features of flood flows. The analysis and ranking of catchment basins are performed using a basin approach. On the basis of SRTM images and the use of stock cartographic material in the GIS program the authors have built specialized electronic maps that allow to obtain quantitative parameters reflecting the morphometry of the basins under analysis including basin geometry, drainage network and terrain relief. On example of the Ulaanbaatar agglomeration territory it is shown how initial morphometric parameters of basins and watercourses (length, width, area, perimeter, erosion dissection, drainage network density, terrain relief coefficient, Melton coefficient, etc.) form the features of flood flow. For developed territories, the initial data on the catchment basin morphometry constitute the basis for compilation of specialized maps to be used in planning and construction. The combination of morphometric indicators on the territory of the Ulaanbaatar agglomeration indicates that there is possibility of large flood formation and development of dangerous mudstone flows in some catchment basins.

Abstract:

The morphometrics of the honey bee Apis mellifera L., 1758 has been widely studied mainly because this species has great ecological importance, high adaptation capacity, wide distribution and capacity to effectively adapt to different regions. The current study aimed to investigate the morphometric variations of wings and pollen baskets of honey bees Apis mellifera scutellata Lepeletier, 1836 from the five regions in Brazil. We used geometric morphometrics to identify the existence of patterns of variations of shape and size in Africanized honey bees in Brazil 16 years after the classic study with this species, allowing a temporal and spatial comparative analysis using new technological resources to assess morphometrical data. Samples were collected in 14 locations in Brazil, covering the five geographical regions of the country. The shape analysis and multivariate analyses of the wing allowed to observe that there is a geographical pattern among the population of Apis mellifera in Brazil. The geographical variations may be attributed to the large territorial extension of the country in addition to the differences between the bioregions.

Abstract:

Abstract Morphologic differentiation among stocks of Mediterranean horse mackerel, Trachurus mediterraneus, throughout the Black, Marmara, Aegean and Eastern Mediterranean Seas, was investigated using morphometric and meristic characters. Discriminant function analysis of both morphometric and meristic characters suggested that there is restricted migration of mackerel among the adjacent seas. Overlapping of four Black sea samples on the discriminant space in morphometric and meristic characters suggested that there is one self-recruiting population in the area. The Marmara sea samples were the most isolated samples from all others for both morphometric and meristic characters, which may indicate existence of a distinguishable mackerel stock in the area. The sample from the Aegean Sea was grouped with one geographically close Mediterranean sample based on morphometrics, and separated from all other Mediterranean samples based on meristic characters, suggesting some degree of intermingling between these areas. Examination of the contribution of each morphometric variable to canonical functions indicated that differences among samples seemed to be associated with the anterior part of the body. In meristic analyses, highest contributions to canonical functions were associated with the number of gill rakers and pectoral fin rays.

Abstract:

Background: Hip bone, also known as the innominate bone, because it is formed by three independent elements during the sub adult life and is directly involved with child birth. The lateral surface of hip bone has a deep cup shaped acetabulum, bounded by a ridge known as rim of acetabulum articulating with the femoral head. The features of acetabulum are characteristic used for sexual dimorphism and for the design of prostheses in Total Hip Arthroplasty. Materials and Methods: Two hundred un paired acetabular part of dry hip bones were collected for this study (50 right male,50 left male,50 right female and 50 left female) from Vinayaka Mission’s Kirupananda Variyar Medical College, Salem. This study is designed to measure Acetabulum transverse diameter, Acetabulum Superoinferior diameter, Total diameter of acetabulum and Depth of acetabulum. Statistical analysis has been done in acetabulum using SPSS 21.0 software and P values were derived by applying unpaired student T test. Results: In the present study, mean value of left sided Acetabulum transverse diameter, Acetabulum superoinferior diameter, Total diameter of acetabulum and Depth of acetabulum among male and female shows 5.24 & 4.9, 5.99 & 5.30, 5.24 & 4.78, 2.60 & 2.43 respectively and all the values are higher in males than females. The mean value of right sided Acetabulum transverse diameter, Acetabulum superoinferior diameter, Total diameter of acetabulum and Depth of acetabulum among male and female shows 5.20 & 4.71,5.26 & 4.89 ,5.2 & 4.72 ,2.67 & 2.35 respectively. All the right sided acetabular parameters are statistically significantly higher among the males as compared with females (P value <.0001), because of strong skeleton and muscle mass and these parameters have minimal role in formation of birth canal. Conclusion: The study of acetabulum may be helpful to the radiologists in diagnosing congenital hip dysplasia. For orthopaedic surgeons in planning before acetabular surgery and treatment of hip joint fractures and to understand the rarity of primary osteoarthritis. The relation between depth and diameter is of immense importance to the Orthopedicians and Radiologists. KEY WORDS: Total Hip Arthroplasty, Acetabulum.

Abstract:

Morphometry is introduced as quantitative approach to seek information concerning variations and changes in the forms of organisms that described the relationship between the human body and disease. Scientists of all civilization, who existed until today, examined the human body using anthropometric methods. For these reasons, anthropometric data are used in many contexts to screen for or monitor disease. Anthropometry, a branch of morphometry, is the study of the size and shape of the components of biological forms and their variations in populations. Morphometrics can also be defined as the quantitative analysis of biological forms. The field has developed rapidly over the last two decades to the extent that we now distinguish between traditional morphometrics and the more recent geometric morphometrics. Advances in imaging technology have resulted in the protection of a greater amount of morphological information and have permitted the analysis of this information. The oldest and most commonly used of these methods is radiography. With developments in this area, CT and MRI have also been started to be used in screening of the internal organs. Morphometric measurements that are used in medicine, are widely used in the diagnosis and the follow-up and the treatment of the disease, today. In addition, in cosmetology use of these new measurements is increasing every day.

The aim of the study is to analyse tibial plateau morphometrically.Methods: The study included 46 human tibia bones (28 left and 18 right). The anteroposterior length and transverse width of superior articular surface of both tibial condyles along with the anteroposterior length and transverse measurements of the intercondylar area were noted with digital Vernier caliper. The data was tabulated and analysed.Results: For the superior articular surface of medial condyle, anteroposterior length was found to be 4.12±0.42cm on left side and 4.17±0.50cm on right side; maximum width was found to be 2.81±0.59cm on left side and 2.78±0.34cm on right side. For the superior surface of lateral condyle, the anteroposterior length was found to be 3.92±0.30cm on left side and 3.66±0.31cm on right side whereas maximum width was found to be 3.12±0.68cm on left side and 2.87±0.55cm on right side. Anteroposterior length of intercondylar area was measured to be 4.31±0.40cm on left side and 4.18±0.44cm on right side. The transverse measurement was recorded to be 3.12±0.68cm (left side), 2.87±0.55cm (right side) anteriorly; 1.25±0.23cm (left side), 1.31±0.20cm (right side) in the middle and 1.28±0.39cm (left side), 1.85±0.42cm (right side) posteriorly.Conclusions: The results will be helpful in orthopaedic surgical procedures involving knee.

Abstract:

Measurement of airway size using endoscopic morphometry was investigated. Endoscopic images of the porcine tracheobronchial tree were obtained via a Storz system at a known distance from the telescope. The bronchi were marked with transluminal wires, transected, and imaged. All images were analyzed morphometrically with a computer image at multiple sites (N = 20). The endoscopic measurements were plotted against the macro lens images so that a straight line with a slope of 1 would indicate a consistent correlation. Area measurements for all images had a slope of 0.67 (r = .885); however, for images with area < 80 mm2 the slope was 1 (r = .928) and for images with area > 80 mm2 the slope was −0.63 (r = .757). Minor axis measurements had a slope for all images of 0.71 (r = .879), for images with area < 80 mm2 of 0.93 (r = .875), and for images with area > 80 mm2 of −0.34 (r = .482), and major axis had a slope for all images of 0.73 (r = .904), for images with area < 80 mm2 of 0.88 (r = .923), and for images with area > 80 mm2 of−0.59 (r = .771). Accurate area measurements as well as major and minor axis measurements can be obtained for airways with area < 80 mm2 by means of this system. Each bronchoscope-telescope unit has an optimal target size for which measurements are accurate.

Abstract:

West Lidder River, in the Northwest Greater-Himalayan mountain range, is the major source of irrigation and drinking water supplies for the Kashmir Valley with a population of seven million people. The major source of water for the whole Lidder River is snow and icemelt emanating from its two subcatchments East Lidder and West Lidder. Snowmelt significantly contributes to the evolution of drainage patterns in this area. Quantitative morphometry plays a vital role in routing the snowmelt and other hydrological processes. Morphometric analysis of the West Lidder River catchment was carried out using geospatial technique. The outcome revealed that the entire study area has uniform lithology and is structurally permeable. The high drainage density of all subwatersheds indicate more surface runoff. The morphometric analysis also indicates that the area is more prone to weathering due to very-coarse to coarse drainage texture. All the subwatersheds showed dendritic to subdendritic drainage pattern. An immense control of structure on the drainage in some subwatersheds is indicated by their high bifurcation ratios. Circulatory and elongation ratios show that the subwatersheds have elongated to circular shapes. From the integrated analysis of the morphometric parameters, important hydrologic behaviour of 17 subwatersheds could be inferred.

Abstract:

The morphometric characters are effectively used for the better differentiation among the fish population and sustainable management. The appraisal of the natural population stock and morphological variation within and between two hilsha species (Tenualosa ilisha and Tenualosa toli) from three different habitat (Coastal, riverine and marine) of Bangladesh, were investigated by applying the land mark based morphometric and meristic variation measurement methods. All data were adjusted and Univariate ANOVA, where discriminant function analysis (DFA) and principal component analysis (PCA) exhibited the divergences in eight morphometric measurements and eight truss network measurements among the three stocks of T. ilisha. The 1st DFA accounted for 89.8% & 87.4% and the second DFA resolved 10.2% and 12.6%, respectively in morphometric characteristics variation among the group studied. Scattered plotting from PCA and dendogram from cluster analysis (CA) revealed that, the river habitants were morphologically different from the coastal and marine population. Twelve of fifteen morphometric measurements and thirteen of fourteen truss network measurements showed significant differences between T. ilisha and T. toil with significant variation in meristic characters. PCA revealed 89.23% and 88.29% in case of morphometric and truss measurement respectively confirmed high degree of variations in morphological characteristics between two species. Overall, our results based on morphometrics with truss measurements together provide useful information about the morphological differentiation which will be helpful for sustainable exploration and effective management for these two species.

Abstract:

Data concerning the morphometric parameters of sheep red blood cells (RBCs) obtained using computer-assisted image analysis have not yet been investigated, and there are no data on any analyses of ovine RBC subpopulations based on their morphometric parameters. The aims of this study are to determine the values of RBC haematological and morphometric size and shape parameters, to form groups according to the obtained values of haematological parameters; to determine the differences in RBC morphometric parameters between the formed groups, and to determine RBC subpopulations and their respective proportions in the formed groups. Thirty-six blood samples were collected from the jugular vein of clinically healthy Lika pramenka sheep, aged between 2 and 5 years. Haematological parameters including haemoglobin (HGB), haematocrit (HTC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and RBC distribution width were analysed using a haematology analyser. Haematological parameters were categorized into two groups: those with lower values or values below the physiological range (Groups 1) and groups with higher values or values above the physiological range (Groups 2). Morphometric parameters of RBCs were determined from stained blood smears using SFORM, a computer-assisted program. Significantly higher values of RBC area, outline, convex, minimal and maximal radius, as well as length and breadth were established in Groups 2 compared to Groups 1 of HGB, HCT, MCV, MCH, and MCHC, respectively. Based on the morphometric parameters of RBCs, three RBC subpopulations were obtained using principal component and cluster analysis: ES 1—the smallest and most elongated RBCs, ES 2—the biggest and most rounded RBCs, and ES 3—average size and shape RBCs. Significantly higher proportions of ES 2 and ES 3 subpopulations, as well as a significantly lower proportion of ES 1 subpopulation, were established in Groups 2 compared to Groups 1 of HGB, HTC, MCV, and MCH, respectively. It can be concluded that ovine RBC subpopulations, based on their morphometric parameters, can be obtained by using computer-assisted image analysis of RBC morphometry and multivariate statistical methods, including principal component and cluster analysis. RBC morphometry, including classification into subpopulations, could serve as a basis for future possibilities in the diagnostic interpretation of anaemic syndromes in veterinary medicine, especially in normocytic, macrocytic, and microcytic anaemias in sheep.

Abstract:

IntroductionThere is ethnic variation in the morphometry of odontoid and it is always mandatory to know the anatomy of odontoid before surgery to achieve the success of the surgery either with 1 or 2 screws fixation. There is no literature on the morphometry of odontoids in the Nepalese population. MethodsTwo hundred and ten consecutive patients whose CT-scan of the head or cervical spine were done without any evidence of cervical injury or fracture were included in the study. Morphometric measurements were done using Horos software in axial, coronal, and sagittal planes. ResultsThe mean age was 42.32 ± 16.16 (range 17-76) years including 104 males and 106 females. The mean screw length was 36.52 ± 3.14 mm and the screw insertion angle in relation to the inferior endplate of C2 vertebrae is 55.66 ± 4.74 degrees. The anteroposterior diameter of the odontoid was significantly more than the transverse diameter at the base and at the waist of the odontoid. A total of 97 (46.1%) individuals had their transverse waist diameter between 7.4 -9 mm and 31 (14.76%)had their dimension below 7.4 mm. ConclusionsAlmost 2/3rd of the Nepalese population has an inadequate diameter of odontoid for two 3.5 mm screws since the transverse waist diameter is less than 9 mm. Hence, either two 2.7 mm screws or a single 4.5 mm screw fixation should be considered in the majority of the cases but only after preoperative CT-scan-based morphometric measurement.
