Abstract:
In plants and all living beings, the fundamental influence comes from ecological factors that operate simultaneously and in a complex manner. The influence of these factors is expressed in the morphological and anatomical features of the vegetative organs of plants, especially the leaves, which are among the most delicate organs where a series of adaptations occur. Although biological science today recognizes approximately 500,000 plant species, they differ from each other morphologically, anatomically, and genetically because they live in different life conditions and circumstances. Understanding the morphological‒anatomical characteristics of plants is highly important for determining their taxonomic and ecological adaptability. This connection between the morphological-anatomical structure of vegetative organs, especially leaves, and external factors has been addressed by many authors: Lakusiç (1962), Greb (1957), Pavlov (1965), Hoxha (1995), Mustafa (1995), and others. To obtain a clearer picture of the impact of ecological factors on the morphological and anatomical characteristics of vegetative organs of plants, we conducted research on the anatomical structure of leaves from different insertions: upper (E) and middle (M) of the plant species Pailurus spina Christi.

Abstract:
The purpose of this study consisted in the identification of the macroscopic and microscopic characters of the vegetative and reproductive organs of Bryonia alba L., by the analysis of vegetal material, both integral and as powder. Optical microscopy was used to reveal the anatomical structure of the vegetative (root, stem, tendrils, leaves) and reproductive (ovary, male flower petals) organs. Histo-anatomical details were highlighted by coloration with an original combination of reagents for the double coloration of cellulose and lignin. Scanning electronic microscopy (SEM) and stereomicroscopy led to the elucidation of the structure of tector and secretory trichomes on the inferior epidermis of the leaf. Micrographic analysis of the powder obtained from aerial parts revealed segments of each organ (e.g. stomata, trichomes) and confirmed furthermore the results obtained by the histo-anatomical studies. Sections achieved through vegetative organs reveal typical anatomical structures: a transition to the secondary structure for the root, a typical dicotyledons’ structure with bicollateral vascular bundles for the stem, a bifacial structure of the leaf and stem-like structures for the tendrils and petioles, which prove they are metamorphosis of the stem. Anatomical structure of reproductive organs was performed hereby for the first time and revealed a typical anatomical structure for the 3-lodged ovary and a leaf-like structure of the male flower petal. Some of the results obtained confirm existing data from the scientific literature and additional information have been provided, outlining features that were not previously reported, such as SEM analysis of the leaf trichomes and histo-anatomical structure of the reproductive organs.

Abstract:
The article presents the results of a study of identification of the characteristics of the bone of the pelvis at the female students of high growth. The aim of the article is the description and analysis of the identified morphological and anatomical and anthropological features of the pelvis of the girls. The methods of the study were pelviometry, anthropometry, method of indices, analysis and statistical processing of the results. The dimensions of the female pelvis, the basis of all professional activities of a midwife as an important subject of pregnancy and birth. Therefore, of particular interest is a comprehensive study of special values of morphological and anthropological indicators, the variability of shapes and size of the pelvis in young women, especially in youth and the first reproductive years, among which is dominated by a female students. As a result of our research in the whole group we obtained the mean value of the index of pelvic bones – 40,53±0,84 cm, indicating a sufficient level of maturity and readiness. In the studied group of students is dominated by tall girl having indicators is not wide or normal and the narrow pelvis – 76,67%. Also noteworthy is the fact that almost every third girl are more or І-III degree of narrowing of the pelvis on the background of its morpho-anthropometric changes, which is quite common among modern girls. It is established that the external dimensions of the pelvis are in close correlation with other dimensions of a woman's body where leading role belongs to the length and body weight. The results of the study indicate that among students of high growth are dominated by those that are shoulder-width apart (35,50±0,86 cm) longer than the width of the pelvis (32,12±0,43 cm). This shows android and not gynecolgy type of construction of the torso of the body, which is not typical for girls. The practical significance of the conducted research consists in the identification of certain violations of reproductive health among this group of students of high growth. It is established that in the future, having identified numerous changes in the structure and shape of the bony pelvis, most of them can have problems during pregnancy and childbirth. The results of the study indicate that among students with high growth are dominated by those that have a shoulder width greater than the width of the pelvis. This shows android and not genecide type of build of the trunk of the body, is not typical for girls. The absolute predominance of different options narrow basins indicates that among modern girls undergoing certain morphological changes in their bodies. Further research will focus on studying the peculiarities of the menstrual cycle in this group.

Abstract:
In order to better understand the functions of plants, it is important to analyze the internal structure of plants with a complex structure, as well as to efficiently monitor the morphology of plants altered by their external environment. This anatomical study investigated structural characteristics of pinecones to provide detailed descriptions of morphological specifications of complex cone scales. We analyzed cross-sectional image data and internal movement patterns in the opening and closing motions of pinecones, which change according to the moisture content of its external environment. It is possible to propose a scientific system for the deformation of complex pinecone for the variable structures due to changes in relative humidity, as well as the application of technology. This study provided a functional principle for a multidisciplinary approach by exploring the morphological properties and anatomical structures of pinecones. Therefore, the results suggest a potential application for use in energy-efficient materials by incorporating hygroscopic principles into engineering technology and also providing basic data for biomimicry research.

Full text
Abstract:
The coronoid process of the mandible is a significant anatomical structure integral to mastication and mandibular stability. It serves as an attachment site for the masseter and temporalis muscles, crucial for jaw movement and function. Beyond its functional roles, it holds therapeutic value in reconstructive craniomaxillofacial surgeries, where it serves as a versatile graft material for addressing osseous defects such as fractures, alveolar defects, and sinus augmentations. Anatomically, it exhibits diverse morphological variations, including triangular, hook-shaped, and rounded forms. These variations not only contribute to understanding anatomical differences but also serve as anthropological markers for ethnic characteristics and ancestry in forensic contexts. Radiographic techniques such as orthopantomograms facilitate the identification and analysis of these morphological differences, essential for both clinical assessments and forensic identifications. Gender-specific differences in its morphology highlight the influence of genetic, hormonal, and developmental factors on mandibular structure. In conclusion, the coronoid process exemplifies a multifaceted anatomical structure with implications spanning clinical practice, anthropological research, and forensic sciences. Understanding its diverse roles and morphological variations enhances surgical outcomes, aids in anthropological studies, and contributes to forensic identifications, emphasizing its enduring relevance in both medical and scientific disciplines.

Abstract:
The acetabulum forms the pelvic bones, together with the head of the femur forms the hip joint, which is the link between the upper part of the body and the lower extremities. The morphology of the acetabulum determines and influences the quality and function of the hip joint. All anatomical and morphological changes of the acetabulum directly affect the development of many diseases of the hip joint. Its anatomical structure and morphological orientation play a major role in the transfer of body weight through the femur to the foot. The acetabulum labrum has the role of increasing the surface of the acetabulum, increasing its depth, reducing contact stress, and preventing direct con-tact between the acetabulum cartilage and the femoral head.

Abstract:
<p> Eye exam can be as efficacious as physical one in determining health concerns. Retina screening can be the very first clue to detecting a variety of hidden health issues including pre-diabetes and diabetes. Through the process of clinical diagnosis and prognosis; ophthalmologists rely heavily on the binary segmented version of retina fundus image; where the accuracy of segmented vessels, optic disc and abnormal lesions extremely affects the diagnosis accuracy which in turn affect the subsequent clinical treatment steps. This thesis proposes an automated retinal fundus image segmentation system composed of three segmentation subsystems follow same core segmentation algorithm. Despite of broad difference in features and characteristics; retinal vessels, optic disc and exudate lesions are extracted by each subsystem without the need for texture analysis or synthesis. For sake of compact diagnosis and complete clinical insight, our proposed system can detect these anatomical structures in one session with high accuracy even in pathological retina images. </p><p> The proposed system uses a robust hybrid segmentation algorithm combines adaptive fuzzy thresholding and mathematical morphology. The proposed system is validated using four benchmark datasets: DRIVE and STARE (vessels), DRISHTI-GS (optic disc), and DIARETDB1 (exudates lesions). Competitive segmentation performance is achieved, outperforming a variety of up-to-date systems and demonstrating the capacity to deal with other heterogenous anatomical structures. </p><p>

Abstract:
Plants that develop under foliar shade encounter both low photosynthetically active radiation (PAR) and low red to far red ratios (R:FR). Both of these factors are important in determining developmental responses to shade. Papaya (Carica papaya L.) seedlings grown under filtered shade (low PAR and low R:FR) were compared with seedlings grown under neutral shade (low PAR with R:FR similar to that of full sunlight), and high light (moderate PAR with R:FR similar to that of full sunlight). The results indicated that papaya exhibits a light seeking strategy as evidenced by morphological and anatomical differences between treatments. Based on past research the results also indicate shade developmental responses in papaya to be phytochrome mediated.

Full text
Abstract:
This research project has attempted to develop a methodology for the identification of charred remains of useful non-woody vegetative parts of plants by the use of morphological and anatomical characters. A large number of taxa have been observed covering a wide morphological, anatomical, ethnographic and taxonomic range. The chosen taxa cover a geographic area from Western Europe, through the Mediterranean to the Near East. Anatomy of fresh material viewed under the light microscope has been used to interpret the anatomy of experimentally charred tissues viewed under the Scanning Electron Microscope. Classical morphological and anatomical characters have been used as well as artifactual characters caused by charring. Literature covering root and tuber domestication and the exploitation of roots and tubers as wild resources are reviewed. The origins of root crops in Europe and the Near East is discussed and compared with the origin of root and tuber crops in the tropics. The application of morphological terms such as rhizome, rootstock and corm as well as the use of anatomical and morphological characters of the tissues under observation for classification and identification are discussed. The results first describe the characters of charred non-woody vegetative tissue, so that in the separate descriptions of the charcoal each taxon that follows the morphology and anatomy may be interpreted. Those characters that are diagnosed are indicated. Archaeological charcoal that has been analysed is also described. The results are discussed with a view to methods of identification of parenchymatous tissues and a manual dichotomous key is presented. Applications of the research are examined. Finally a list of concluding points is put forward.

Abstract:
AbstractThe relationship between sexual selection and the diversity and rapid evolution of male genitalia has been well-documented across many animal taxa, while the morphological variability of female genitalia has received comparatively little attention. Female whales, dolphins, and porpoises possess unusual flaps, folds, and blind sacs in their vaginas, which vary among taxa and may serve several functions. We review the relationship between form and function of these unusual vaginal structures in cetaceans and discuss evidence that supports or refutes various functional hypotheses. A compilation of three-dimensional vaginal endocast models, contemporary high-resolution photographs of dissected reproductive tracts, and detailed anatomical illustrations ranging over 175 years are used to highlight the diversity of forms and fill in gaps in taxonomic knowledge. We discuss the complementary nature of anatomical illustrations and modern analytical and visual tools and how they can help us better understand the evolution of such unusual morphological structures. We identify opportunities for future studies in cetacean genital evolution and discuss the insights they may provide into mating strategies of cetaceans.

Abstract:
The article provides a comparative analysis of the morphological and anatomical structures of annual layers in the long moss pine forest (Pinetum polytrichosum) and the wild rosemary pine forest (Pinetum ledosum). It has been established that the radial diameter of the early and late tracheids and their cavities, the area of the cell wall and the area of the cavity of the early and late tracheids, as well as the number of late tracheids in the radial row of the annual layer can serve as markers for differentiating these forest types, even in spite of fairly similar conditions growth.

Abstract:
In the presented work, based on many years of research and generalization of surveys of the hanging birch, the issues of the modern agroecological state of the environment in which it is not always favorable not only for humans, but also for all living organisms are highlighted. Green spaces are important in urban systems, which perform many important functions: from oxygen saturation of the air to dust and noise absorption. Being a part of urban ecosystems, trees and other plant groups fully feel the negative impact of the urban environment, especially the increase in MPC. Modern methods of environmental monitoring make it possible to assess the state of the environment based on morphological, anatomical and other changes in the structure of green organisms, in particular leaf asymmetry.

Full text
Abstract:
The meniscus is comprised of two semilunar disks resting between the articular surface of the tibial plateaus and femoral condyles within the knee joint of each leg [1–3]. Both the medial and lateral menisci play a vital role in maintaining the joint’s integrity by distributing loads, stabilizing and lubricating the joint, and proprioceptive functions [2,3]. While the meniscus is found in many animals, morphological variations are present between species, indicating differences in the biomechanics of the joint [1,2]. These anatomical variations have not been quantified and, thus, remain unlinked to further structural changes that occur with injury. The goals of this study were aimed towards characterizing the normal lapine meniscal tissue using regional comparisons for tissue area and cell density measurements. The preliminary data from this research will be used as a comparison against future animal injury models. It was hypothesized that a difference would be observed between anterior, central, and posterior divisions in the normal lapine meniscus.

Full text
Abstract:
Femoroacetabular impingement (FAI) is an anatomical hip condition caused by malformations on femoral head and acetabular rim resulting in abnormal contact across the joint. FAI can cause the labral, cartilaginous, and tissue damage that leads to early osteoarthritis. FAI can be divided into three groups: cam (bump on femoral head- neck junction), pincer (acetabular over coverage), or mixed (most common) by the characteristic morphological changes of the bony structures. The exact ethology of FAI is still unclear, mostly considered as idiopathic. Cam lesions demonstrate a near 3:1 male predominance and are more often seen in the younger population. Pincer is typically seen in middle-aged women. A plain radiography of the pelvis and hips is considered as the primary imaging modality for diagnosing FAI, which can be used to quantify the severity. MRI and direct MRI arthrography allow assessment of concomitant labral and chondral injuries. Conservative treatment is typically considered first-line treatment for mild to moderate FAI syndrome, but usually not to successful. However, the outcomes following postoperative surgical intervention have demonstrated excellent results. The most common surgical treatment option for FAI is done arthroscopically, other procedures such as a reverse periacetabular osteotomy or surgical dislocation of the hip are rarely indicated. Keywords: Femoroacetabular impingement; cam, pincer; hip arthroscopy

In III SEVEN INTERNATIONAL MULTIDISCIPLINARY CONGRESS. Seven Congress, 2023. http://dx.doi.org/10.56238/seveniiimulti2023-086.

Full text
Abstract:
Introduction: The sacrum, formed by the union of the five sacral vertebrae, is positioned at the base of the spine and between the two hip bones. These vertebrae begin to fuse between 16 and 18 years of age and end around 30 years of age. However, in some cases, this structure may suffer anatomical variations, such as agenesis of the dorsal wall of the sacrum, which is a failure in the union of the laminae of the sacral vertebrae. Objective: To analyze the frequency of complete agenesis of the dorsal wall of the sacrum and its clinical and surgical implications. Methodology: A descriptive morphologic and anthropometric study was performed with 45 sacrums of unknown sex and age. The length of the sacral canal was calculated using a digital caliper with 0.01 mm precision. Results: Complete agenesis of the posterior wall of the sacrum was observed in 2 of the 45 sacrums analyzed (4.44%). In the first case, the length of the sacral canal was 110 mm. A triangular shape was observed in the proximal two-thirds and a quadrangular shape in the distal third, with a narrowing between the third and fourth sacral vertebrae. In the second case, the length of the sacral canal was 96 mm, and a triangular shape was observed in the proximal and middle thirds, with a narrowing between S2-S3 and a quadrangular shape in the distal third, with a narrowing between S4-S5. Conclusion: The study of this anatomical variation was necessary, since its occurrence has been persistent and its knowledge can reduce the failures made by clinicians and surgeons in the application of caudal epidural anesthesia, in the diagnosis of low back pain or even in the treatment of congenital diseases, for example meningocele and myelomeningocele.

Abstract:
The production of semantic annotations has gained renewed attention due to the development of anatomical ontologies and the documentation of morphological data. Two methods are proposed in this production, differing in their methodological and philosophical approaches: class-based method and instance-based method. The first, the semantic annotations are established as class expressions, while in the second, the annotations incorporate individuals. An empirical evaluation of the above methods was applied in the morphological description of Neotropical species of the genus Lepidocyrtus (Collembola: Entomobryidae: Lepidocyrtinae). The semantic annotations are expressed as RDF triple, which is a language most flexible than the Entity-Quality syntax used commonly in the description of phenotypes. The morphological descriptions were built in Protégé 5.4.0 and stored in an RDF store created with Fuseki Jena. The semantic annotations based on RDF triple increase the interoperability and integration of data from diverse sources, e.g., museum data. However, computational challenges are present, which are related with the development of semi-automatic methods for the generation of RDF triple, interchanging between texts and RDF triple, and the access by non-expert users.

Full text
Abstract:
Original objectives: Anatomical study of storage root initiation and formation. Induction of storage root formation. Isolation and characterization of genes involved in storage root formation. During the normal course of storage root development. Following stress-induced storage root formation. Background:Sweetpotato is a high value vegetable crop in Israel and the U.S. and acreage is expanding in both countries and the research herein represents an important backstop to improving quality, consistency, and yield. This research has two broad objectives, both relating to sweetpotato storage root formation. The first objective is to understand storage root inductive conditions and describe the anatomical and physiological stages of storage root development. Sweetpotato is propagated through vine cuttings. These vine cuttings form adventitious roots, from pre-formed primordiae, at each node underground and it is these small adventitious roots which serve as initials for storage and fibrous (non-storage) “feeder” roots. What perplexes producers is the tremendous variability in storage roots produced from plant to plant. The marketable root number may vary from none to five per plant. What has intrigued us is the dearth of research on sweetpotato during the early growth period which we hypothesize has a tremendous impact on ultimate consistency and yield. The second objective is to identify genes that change the root physiology towards either a fleshy storage root or a fibrous “feeder” root. Understanding which genes affect the ultimate outcome is central to our research. Major conclusions: For objective one, we have determined that the majority of adventitious roots that are initiated within 5-7 days after transplanting possess the anatomical features associated with storage root initiation and account for 86 % of storage root count at 65 days after transplanting. These data underscore the importance of optimizing the growing environment during the critical storage root initiation period. Water deprivation during this phenological stage led to substantial reduction in storage root number and yield as determined through growth chamber, greenhouse, and field experiments. Morphological characterization of adventitious roots showed adjustments in root system architecture, expressed as lateral root count and density, in response to water deprivation. For objective two, we generated a transcriptome of storage and lignified (non-storage) adventitious roots. This transcriptome database consists of 55,296 contigs and contains data as regards to differential expression between initiating and lignified adventitious roots. The molecular data provide evidence that a key regulatory mechanism in storage root initiation involves the switch between lignin biosynthesis and cell division and starch accumulation. We extended this research to identify genes upregulated in adventitious roots under drought stress. A subset of these genes was expressed in salt stressed plants.

Full text
Abstract:
The Old River Control Complex (ORCC) consists of the Low Sill, Auxiliary, and Overbank structures as features of the Old River Control Structure (ORCS) and the privately owned hydro-electric power plant. Operations of the ORCC manage the hydrologic connectivity between the Mississippi River and the Atchafalaya River/Red River systems. The morphology of the Old, the Mississippi, the Atchafalaya, and the Red Rivers (OMAR) has been influenced by the flow distribution at the ORCC, as well as the accompanying bed sediments. A geomorphic assessment of the OMAR is underway to understand the morphological changes associated with operation of the ORCC. Supporting the geomorphic assessment, a channel geometry analysis herein documents observed adjustments of the affected river channels. Historical hydrographic survey data were used in the Geographic Information System to create river channel geometric models, which inform the analysis. Geometric parameters for cross sections and volume polygons were computed for each survey and evaluated for morphological trends which may be ascribed to the influence of the ORCC. Additionally, the geometric parameters for the Atchafalaya River were used to extend the geometry analyses from the 1951 Mississippi River Commission report on the Atchafalaya River, which was the primary catalyst for the initial development of the ORCS.

Intraoperatively Diagnosed Double Cystic Duct During Laparoscopic Cholecystectomy: A Case Report of a Surgical Dilemma for the Operating Surgeons. Science Repository, 2024. http://dx.doi.org/10.31487/j.ajscr.2024.01.04.

Full text
Abstract:
Introduction and Importance: A double cystic duct with a single gallbladder is one of the extremely uncommon variations of the cystic duct and only a few cases were reported in literature. Case Presentation: A 33-year-old female, with an unremarkable medical history, presented to the emergency department with a 2-day history of right upper quadrant abdominal (RUQ) pain. The abdominal pain was gradually increasing in intensity radiating to the back and was associated with anorexia and multiple episodes of vomiting. Abdominal examination revealed RUQ pain and tenderness. Abdominal ultrasonography was performed, showing a markedly distended gallbladder with evidence of a few calculi one of which was impacted at the neck. laparoscopic cholecystectomy was done within 2 days of admission during which another luminal structure was identified that suggested a double cystic duct. Clinical Discussion: Anomalies of the biliary tree are common with the classical anatomical picture presenting in only 33% of cholecystectomy cases. However, the presence of a double cystic duct is a rare variation, especially in the case of a single gallbladder. The identification of such anomaly can be achieved preoperatively using imaging modalities or it can be identified during the surgical procedure itself. such identification reduces the chances of postoperative comorbidities. Conclusion: Pre-operative identification of biliary tract anomalies by different imaging modalities is limited. Hence the importance of cautiousness and achieving a proper critical view of safety intra-operatively to prevent possible complications intra- and post-operatively. Our case report emphasizes the diagnostic and surgical challenges of the double cystic duct.

Full text
Abstract:
Research on seeps and springs in the eastern United States is limited and few protocols for documenting and inventorying these valuable eastern ecosystems have been established. In the Chattahoochee River National Recreation Area (CRNRA), seeps and springs may host species of concern and represent hotspots of biodiversity within an already biodiverse park. This project’s goal was to survey the entire park to identify seeps and springs, collect location data, document the hydrogeology and ecology of these systems, and determine sites for future study. Additionally, classification terminology was adapted from the Springs Stewardship Institute’s Springs Ecosystem Inventory Protocols to create a classification scheme for seeps and springs in the Piedmont ecoregion (Stevens and Ledbetter 2023; A. Cressler, personal communication). These classifications were primarily based on the morphology and hydrologic conditions of the emergence point of the springs, which influence the structure of the spring and the habitats it may support. Seeps and springs were divided into four broad morphological categories: ravine, hillslope, floodplain, and bluff. The data from this study has already conveyed benefits to natural and cultural resource management in the CRNRA. GIS layers have been updated to include seeps and springs sites in consideration for future project authorization, which will help preserve the delicate structure of these ecosystems. Information concerning historic structures associated with seeps and springs has been documented. In addition, the park now has an extensive dataset of floristic species presence and water quality measurements spanning the length of the park, which can be used as reference data in future studies. Further in-depth studies of a smaller number of seeps and springs will be undertaken in a planned Level 2 study.

Abstract:
In this study, trend of stem cell-based treatment for diabetes type 1 in veterinary practice has been preliminarily investigated. Production of pancreatic lineages by canine bone marrow-derived mesenchymal stem cells (cBM-MSCs) using genetic manipulation approach has been studied. Transfection efficiency of second-generation lentiviral vector on cBM-MSCs employing “pLenti CMV GFP Puro (658-5)” (Addgene plasmid #17448) was investigated and the results suggested the susceptibility of the cell to such transfection. Further study was performed to evaluate the efficiency of PDX1 transfection on cBM-MSCs, focusing on cell fate after transfection. The lentiviral vector containing “pWPT-PDX1 plasmid” (Addgene plasmid # 12256) was used. The multiplicity of infection (MOI) 20, 30, and 50 were employed. The results illustrated that PDX-1 transfection could enhance dose- and time-dependent cell morphological change toward colony-like structure. Some of pancreatic gene markers were also upregulated. Upon the induction by modified three-dimension (3D) micro-environmental manipulating protocol, “hanging drop-culture technique” and “hanging-drop culture technique with Matrigel-formed dome culture technique” could effectively enhance pancreatic differentiation by cBM-MSCs. Further study on integrating hanging drop-cell culture technique with genetic manipulation illustrated that cBM-MSCs could be differentiated toward pancreatic lineage with dramatic expression of pancreatic mRNA markers. Thus, this study demonstrated that cBM-MSCs could be used as the source of pancreatic lineage derivation by using integration of genetic and microenvironmental manipulating protocol in vitro

Wieting, Celeste, Sara Rathburn, and John Kemper. Evaluation of gully erosion for archaeological preservation in Wupatki National Monument. National Park Service, 2024. http://dx.doi.org/10.36967/2302447.

Full text
Abstract:
Wupatki National Monument contains an abundance of prehistoric and historic archaeological sites that are vulnerable to gully erosion from heavy sporadic rainstorms. Increased erosional risks are predicted as more extreme weather causes frequent or intense rainfall, flooding, and gullying. At Wupatki National Monument, gullies generally form on hillslopes within volcanic-derived cinders that are ubiquitous across the landscape and are unconsolidated, non-cohesive, highly mobile, and permeable. Lithological differences between volcanic cinders and underlying sedimentary rocks, and surface runoff influence the progression of gully erosion near archaeological sites. We assessed gullies based on changes in gully morphology and categorized archaeological sites based on vulnerability from erosion and runoff processes. We found that 35 measured gullies are actively eroding, with statistically significant changes in gully depth from 2016 to 2021. Up to 0.5 m of incision was documented over a five-year period. A structure from motion analysis at the hillslope scale confirmed gully morphological changes and supports the applicability of conducting similar analyses on a larger scale. More erosion occurred in gullies with catchments predominantly covered with cinders because of cinder mobility. We noted a weak relationship between gully catchment area and gully head slope, likely related to runoff processes from outcrops of resistant sedimentary rocks forming cliffs and characteristics of cinders that maximize infiltration and transport. Based on our assessment of gully morphologic change and substrate characteristics, 22 archaeological sites along Wupatki Wash were identified as having a high vulnerability to erosion, helping monument managers to prioritize their monitoring initiatives.

Thomas, Strobel. A contrastive approach to grammatical doubts in some contemporary Germanic languages (German, Dutch, Swedish). Goethe-Universität Frankfurt a.M., 2023. http://dx.doi.org/10.21248/gups.72278.

Full text
Abstract:
Unquestionably (or: undoubtedly), every competent speaker has already come to doubt with respect to the question of which form is correct or appropriate and should be used (in the standard language) when faced with two or more almost identical competing variants of words, word forms or sentence and phrase structure (e.g. German "Pizzas/Pizzen/Pizze" 'pizzas', Dutch "de drie mooiste/mooiste drie stranden" 'the three most beautiful/most beautiful three beaches', Swedish "större än jag/mig" 'taller than I/me'). Such linguistic uncertainties or "cases of doubt" (cf. i.a. Klein 2003, 2009, 2018; Müller &amp; Szczepaniak 2017; Schmitt, Szczepaniak &amp; Vieregge 2019; Stark 2019 as well as the useful collections of data of Duden vol. 9, Taaladvies.net, Språkriktighetsboken etc.) systematically occur also in native speakers and they do not necessarily coincide with the difficulties of second language learners. In present-day German, most grammatical uncertainties occur in the domains of inflection (nominal plural formation, genitive singular allomorphy of strong masc./neut. nouns, inflectional variation of weak masc. nouns, strong/weak adjectival inflection and comparison forms, strong/weak verb forms, perfect auxiliary selection) and word-formation (linking elements in compounds, separability of complex verbs). As for syntax, there are often doubts in connection with case choice (pseudo-partitive constructions, prepositional case government) and agreement (especially due to coordination or appositional structures). This contribution aims to present a contrastive approach to morphological and syntactic uncertainties in contemporary Germanic languages (mostly German, Dutch, and Swedish) in order to obtain a broader and more fine-grained typology of grammatical instabilities and their causes. As will be discussed, most doubts of competent speakers - a problem also for general linguistic theory - can be attributed to processes of language change in progress, to language or variety contact, to gaps and rule conflicts in the grammar of every language or to psycholinguistic conditions of language processing. Our main concerns will be the issues of which (kinds of) common or different critical areas there are within Germanic (and, on the other hand, in which areas there are no doubts), which of the established (cross-linguistically valid) explanatory approaches apply to which phenomena and, ultimately, the question whether the new data reveals further lines of explanation for the empirically observable (standard) variation.
