Development of the Mars Helicopter Rotor System
Authors:   AeroVironment Inc., Pipenberg Benjamin , Keennon Matthew , Langberg Sara , Tyler Jeremy
Published: July 2023

The Mars Helicopter is a 1.8 kg coaxial rotorcraft designed to demonstrate aerial mobility at the surface of Mars after deployment from the Mars 2020 rover. In this paper, the authors present the development of the Mars Helicopter rotor system from preliminary design through fabrication and testing of the flight hardware. The vehicle has a 1.21 m counter-rotating coaxial rotor system which is driven by electric motors and which features collective and cyclic controls on both the upper and lower rotor sets. The rotor blade design is characterized by the low Reynolds number (∼104), high Mach number (∼0.7), high stiffness (first flap frequency ∼1.9/rev), and minimum mass. Airfoil design focused on minimizing drag at the low operating Reynolds number while maintaining sufficient spar depth for structural requirements, and the blade planform was based on a minimum induced loss profile with modifications to reduce mass of the outboard blade sections for increased flap frequency. The swashplate and servos were designed to provide actuation of the rotor at up to 12Hz bandwidth while minimizing system mass and volume, and the primary structure of the rotor blades and hubs relies heavily on molded carbon fiber composites and ceramic ball bearings.
Advanced Technology, Lightweight, Multifunctional Micro-avionics for Manned and Unmanned Rotorcraft Enhance Operational Capability of Future Vertical Lift Platforms

Published: July 2023

Emerging microelectronic technologies are expanding functionalities for future decades of vertical lift platforms, enabling both manned and unmanned rotorcraft to fully and safely participate in the NextGen National Airspace System. Specifically, for rotorcraft, benefits from expanded multi-functionality and reduced weight and space requirements, for both mandatory and desired optional avionics, are entering advanced development and flight-testing stages prior to being available to all users. One has only to think about the incredible, multifunctional capabilities of a smartphone to imagine what is possible in avionics with today's advanced technology. This presentation discusses achievements that only a few years ago were beyond imagination - miniaturized avionics that fully employ tiny but powerful digital processors and software defined multi-functional systems on a single chip are rapidly obsoleting the "black boxes" of the past. For both manned and unmanned rotorcraft systems, the benefits must be validated; and when proven valid, are immense in terms of lighter weight, tiny form factors, and lower costs. This presentation also addresses validation of ADS-B2, which depends on verification of GPS signals with technological approaches that counter potential malicious spoofing, jamming and interference.
A Holistic Approach to Open Systems Architecture for Army Aviation
Authors:   JHNA, Stough John ,   Consultant, DuBois Tom ,   US Army PEO Aviation, Hyatt Leslie , Hammond Alan , Kellow Chris
Published: July 2023

The Army is pivoting to meet the challenges of a rapidly evolving threat environment in an increasingly complex world; this requires an agile and adaptive capability, leveraging competition, while operating within the constraints of current budget cycles. A cross cutting architectural approach provides opportunity for the Army to maintain capability overmatch. Recent changes in acquisition law and Army modernization strategy bring particularly strong emphasis on adoption of Modular Open Systems Approach (MOSA) and Open Systems Architecture (OSA). Many current programs within Army Aviation rely on a best effort approach ("Do MOSA") to deliver systems. Current programs measure success on cost, performance, and schedule of the individual program with little historical institutional support for aligning efforts across a larger "whole-system" context, such as a Combat Aviation Brigade (CAB). Specific programs, including the Utility Helicopter Program Office (UHPO) UH-60V and Crew Mission Station (CMS), as well as multiple Science & Technology (S&T) programs supporting Future Vertical Lift (FVL) such as the Mission Systems Architecture Demonstration (MSAD), that exhibit aspects of the architectural momentum in the Army enterprise. The recommendation of our team is to develop an Army Aviation Enterprise Architecture Strategy that will provide the detail necessary in order to develop individual product lines while providing synergy in architecture related efforts into a holistic approach maintaining focus on Army Aviation as a whole force in support of and integrated with the ground commander.

Authors:   US Army Aeromedical Research Lab, Feltman Kathryn , Bernhardt Kyle , Hayes Amanda
Published: July 2023

Two sets of visual symbology in conjunction with two display types (helmet mounted and panel mounted) were examined for their usability in maintaining flight performance within a simulated degraded visual environment. Eight rated Army Aviators completed a series of flights using the two symbology sets with each display type. Flight performance data was collected and used to assess performance resulting from symbology and display used. Overall, the assessment found one symbology set to result in better performance across several phases of flight and no significant differences due to display type, although a few interactions between symbol set and display type are noted.
Numerical Analysis of RPM effect on Dynamic Stall Phenomena on Helicopter Rotor at High Thrust Forward Flight
Authors:   ONERA, Castells Camille , Richez François , Costes Michel
Published: July 2023

Dynamic stall is a highly complex phenomenon characterized by unsteady massive separated flow. It limits the flight envelope of helicopters by generating vibrations and large dynamic loads which can lead to fatigue and structural failure of blades. Dynamic stall involves several mechanisms which make the numerical prediction of stall difficult and the understanding of the phenomenon still incomplete. A loose coupling methodology between a Computational Fluid Dynamics and a Comprehensive Analysis codes is used to simulate the problem. Three stalled flight conditions have been selected in the wind tunnel 7A rotor test data to investigate the RPM effect on the dynamic stall onset and the related mechanisms. The lower the RPM, the more severe the stall is. A double stall has been observed on the lowest RPM case. The coupled simulations are in satisfactory agreement with experiment and are used to identify the mechanisms leading to stall. Simulations indicate that the blade-vortex interaction is an important factor in triggering the different stall events in these configurations.

Authors:   University of Stuttgart, Öhrle Constantin ,   Airbus Helicopters, Embacher Martin , Frey Felix , Thiemeier Jakob , Keßler Manuel , Krämer Ewald , Cranga Paul , Eglin Paul
Published: July 2023

This work presents the correlation of simulation results and flight test data for a high-speed (V =220kts), high advance ratio (μ > 0.5) flight of the compound helicopter X3. The simulation tool chain consists of state-of-the-art coupling between the computational fluid dynamics (CFD) code FLOWer and the comprehensive analysis (CA) tool HOST. By applying a free-flight trim procedure, the experimental flight state is accurately represented in the simulation. The deviations of most trim controls is below 1° and the maximum deviation is less than 1.4°. The analysis of the high fidelity CFD results illustrates key features of the flow physics at this high advance ratio, such as wake interactions, reverse flow and advancing side loading. The correlation of rotor dynamics data between simulation and flight test is favorable. Good accordance is demonstrated for flap bending moments, torsion moments and pitch link loads. In contrast, the correlation is weaker for the chord bending moments for which it is shown that the interblade damper and drive train model mostly determine the structural loads.
Drivetrain Influence on the Blade Loads of Hingeless Helicopter Rotors
Authors:   German Aerospace Center - DLR, Weiss Felix , Kessler Christoph
Published: July 2023

The impact of structural rotor-drivetrain interaction on the blade loads of the Bo105 helicopter is investigated by numerical simulation. For this purpose, the constraint of constant rotor hub speed is dropped and a drivetrain model, consisting of discrete inertia elements and intermediate flexible elements, is connected to the hub. The structural rotor-drivetrain system is coupled to an aerodynamic model consisting of an analytical formulation of unsteady blade element loads combined with a generalized dynamic wake. A time-marching autopilot trim of the rotor-drivetrain system in wind tunnel configuration is performed for a large blade loading flight state as well as a high advance ratio flight state. The comparison of the simulation results with those of a baseline case (constant rotor hub speed) reveals a major drivetrain influence on the blade lead-lag load harmonics at blade passage frequency. Beside the full drivetrain model, reduced models are shown to be capable of predicting the drivetrain influence on blade loads, if they yield the same eigenfrequency of the coupled rotor-drivetrain mode wRDL2 (second collective lead-lag mode couples with drivetrain) as the full model. In a sensitivity analysis, wRDL2 is varied by modification of the stiffness of a reduced drivetrain model. The resulting changes in blade loads are correlated to wRDL2 , which serves as a simple but accurate classification of the drivetrain regarding its influence on vibratory blade loads. Finally, the improvement of lead-lag load prediction by the application of a drivetrain model is demonstrated through comparison of simulated loads with measurements from a wind tunnel test.

Published: July 2023

This study using IBC (Individual Blade pitch Control) attempts to reduce the hub vibratory loads of a lift-offset rotor in high-speed forward flight while the rotor performance is maintained or improved. The rigid coaxial rotor of XH59A compound helicopter is considered as a lift-offset rotor for the present work and CAMRAD II is used to calculate the hub vibration and performance of a rotor. The single harmonic input the using 3/rev actuation frequency, amplitude of 1°, and control phase angle of 270° (3P/1°/270°) for the IBC minimizes the vibration index of the XH-59A rotor at 200 knots by about 62%, but it reduces the rotor effective lift-to-drag ratio by 3.43%. When the 2/rev actuation frequency with the amplitude of 2° and control phase angle of 270° (2P/2°/270°) and the 3/rev actuation frequency using the magnitude of 1° and control phase angle of 210° (3P/1°/210°) are used in combination for the IBC with multiple harmonic inputs, the rotor vibration is reduced by about 62%, while the rotor performance increases by 0.37% at 200 knots. This study shows that the hub vibration of the lift-offset rotor in high-speed flight can be reduced significantly (by above 50%) but the rotor performance is maintained or improved moderately, using the IBC with multiple harmonic inputs.
Experimental Strain Measurements of Highly-Curved Blades
Authors:   University of Maryland, Sinotte Tyler , Bauchau Olivier
Published: July 2023

This paper presents an experimental-numerical investigation on the axial strain of highly-curved blades. Models of the blades were analyzed using a 2-D finite element code, SectionBuilder, coupled with a comprehensive analysis code, Dymore, and first validated using strain measurements under a static tip load. Frequency responses were obtained under an impulsive load for each of the blades with multiple boundary conditions and compared with the numerical models. Experimental measurements under centrifugal loading from 0 up to 3300 RPM in a vacuum showed the effect of curvature on the axial strain, with significant bending strains observed in the responses for the curved blades that were also well captured by the numerical analysis. The present analysis shows that even moderate levels of out-of-plane curvature significantly increases the strain magnitudes, while higher levels of in-plane curvature have a much smaller impact.

Indonesia’s fintech industry has continued to experience rapid growth and will emerge as a key participant in the country’s financial sector by 2022-2023. Fintech is an abbreviation for financial technology, which refers to the use of technology to improve the efficacy of financial systems and provide financial services. Indonesia is an ideal environment for the growth of fintech companies due to its large population and swiftly expanding middle class. The widespread adoption of smartphones and internet access has contributed to the expansion of fintech in the nation. The Financial Services Authority (OJK) has implemented measures to promote innovation, safeguard consumers, and maintain financial stability. These rules have facilitated the operation of fintech firms and attracted investment. In Indonesia, mobile payment solutions are one of the fastest-growing areas of fintech. In banking industries, technology is beginning to transform the banking process from traditional banking to digital banking, in which consumers must deliver through innovative technologies such as mobile and internet banking (Abbasi & Weigand, 2017). This issue may be remedied by the emergence of fintech lending. This was bolstered by the high mobile subscription and internet penetration rates relative to Indonesia’s population, which subsequently presented a tremendous opportunity for fintech lending platforms.

As the textile manufacture is one of the biggest industry that producing waste, many people start to aware of this problem, especially millennials and gen Z. Many fashion brand are starting to apply sustainability process on their manufacture, including applying slow and circular fashion concept. As a sustainability brand, they tend to use value-based pricing on their pricing strategy, so the price range is middle to high. The brand wanted the value they offer to the consumers is delivered well and they tried to encourage people to be responsible consumers. However, the one who have awareness of environment concern are millennials and gen Z who have middle to low purchasing power. This generation sees the value that sustainability brand’s offer is not appeal to them even though they know the brand mission and vision. This study aimed to identify factors that influence the consumers purchase intention on slow and circular fashion concept. This study using quantitative methods and descriptive statistic as data collection methods. The data were obtained from questionnaire that were distributed to 200 respondent.

The Covid-19 pandemic led individuals, business community, nations and the world in general to many problems. In the context of Rwanda, Covid-19 pandemic spread rapidly within a short period of time resulted into serious problems including unemployment. This paper aims to assess the effects of Covid-19 pandemic on employment situation in Kigali city, Rwanda focusing on how Covid -19 pandemic cases have been spread in Kigali city, finding out the most affected economic sectors by Covid-19 pandemic and assessing the extent to which Covid-19 pandemic caused unemployment in Kigali city, Rwanda. The study targeted unemployed and laidoff people due to Covid-19 pandemic from whom 96 respondents were selected using Alain Bouchard formula. Data were collected using questionnaire, interview and documentation and analysed using descriptive statics frequency, percentage and Pearson correlation test. The main findings indicated that the spread of Covid-19 has been rapid in kigali city whereby Covid-19 positive cases had reached on 3,452 in Kigali City for the period of almost 9 months. Unemployment caused by Covid-19 pandemic affected people in Kigali city from various sectors in different ways. Construction; education; domestic works; betting games and marriage activities; and industry, tourism and restaurant have been respectively revealed the most affected economic sectors by unemployment due to Covid-19 pandemic in Kigali City. The people in informal and private sectors are the most affected. Moreover, the statistical evidence reveals a significant positive correlation between covid-19 pandemic and unemployment in Kigali city. This implies that the more the Covid-19 confirmed positive cases, the more the cases of unemployment (laidoffs and forced unpaid leaves). There is hence a need for public-private partnership to put in place the measures that can protect people working in informal and private sectors as they are the most affected.

Cardiac involvement in polymyositis and dermatomyositis: diagnostic approaches.
Authors: Trybuch Agnieszka , Tarnacka Beata
Published: July 2023

Polymyositis (PM) and dermatomyositis (DM) are rare idiopathic inflammatory myopathies (IIM). Myocardial involvement in patients with IIM is an unfavorable prognostic factor and one of the most common cause of mortality in this group of patients. The purpose of this review is the presentation of current knowledge on cardiovascular manifestations observed in IIM. Published in English data until December 2021 were selected. Clinical symptoms suggesting cardiac involvement are non-specific and require a differential diagnosis in accordance with cardiological guidelines. Troponin I is specific to cardiac injury and should be preferred to other markers to evaluate the myocardium in IIM. Abnormalities in electrocardiography are common in IIM , especially non-specific changes of ST-T segment. In standard echocardiography left ventricular diastolic dysfunction is reported frequently. New diagnostic technologies can reveal clinically silent myocardial abnormalities. However, prognostic value of subclinical impairment of myocardial function require further studies.

Introduction. Intracerebral hemorrhages represent the second most frequent, but the most severe form of stroke, with 1 in 3 patients passing away shortly after its debut. Considering these data, it is necessary to identify efficient ways to evacuate intracerebral hematomas and improve their morbidity and mortality, with brain imaging being truly helpful to neurosurgeons. Objectives. To identify the role of imaging for the evacuation of spontaneous intracerebral hematomas. Methods. We performed an extensive literature review, examining the latest published studies and therapeutic protocols. We performed a comprehensive evaluation of the latest imaging and surgical techniques for the diagnosis and treatment of intracerebral hemorrhages. Results. These studies suggest that surgical intervention and evacuation of the hematoma, based on imaging and clinic, can have an immediate lifesaving effect on certain groups of patients, but it does not significantly influence the long-term prognosis and death rate. Conclusions. Modern imaging techniques help neurosurgeons preoperatively, as they can more accurately estimate the benefits of the surgical intervention, intraoperatively through neuronavigation, and postoperatively, modulating therapeutic management by identifying specific imagistic signs. Surgical interventions, both invasive and especially minimally invasive, have a proven positive effect on the evolution of patients, reducing acute mortality, but with uncertain results regarding improving long-term prognosis.
3D Printer planning the production of weapon parts in the shortest possible time

Published: July 2023

This study presents a mathematical model to optimise the production of weapon parts using a 3D printer using parallel machine planning. After the battle with the enemy is over, many weapons will be damaged. Damaged weapons are classified as full, medium or minor damage. Among these, weapons with minor damage can be used again immediately after repair, simply by replacing the damaged or missing part. However, due to the constant movement of troops around the battlefield, carrying thousands of weapon parts is not practical. To remedy this situation, a 3D printer can be carried in a separate unit and the necessary parts can be produced in the field to repair even minor weapon damage. A model for scheduling the production of the necessary parts in a short period after each battle is over is proposed for this purpose. A set of multiple 3D printers can operate as a parallel machine and produce different parts. The 3D printers can produce a finished product for each part simultaneously or produce two separate parts for each part, but if they make individual parts, this increases the burden on that part due to the production of additional fasteners for assembly. That is, in the case of making individual parts, the total production time for that part will be longer compared to the case of making the finished product immediately. Nevertheless, this study confirms that by introducing a sub-batch fabrication concept of weapon parts, the production time can be reduced when planning the production schedule of a 3D printer.

Turkey has one of the strongest militaries not only in its immediate neighborhood but also in Europe and within NATO. In this paper the development of the Turkish military and the military complex is examined from a historical perspective beginning from the early republic to the current situation with the political and international developments which affected this development. The transformation of the Turkish army from an obsolete but large land army to a modern one with some leading technologies in fields such as drones and infantry weapons is divided into four periods based on important political turning points which caused deep changes within the Turkish military in return. Most of the views on political matters are however, reflecting the Turkish point of view among the public and politicians, and therefore might differ from the general point of view in other parts of the world. But it was necessary to mention them to better understand the intrinsic reasons for the changes that took place.
A Key Factor in Vienna Becoming the “Greenest City” in 2020 was the Paradigm Shift in the Transport System 50 Years Earlier
Authors: Knoflacher Hermann
Published: July 2023

Until the 1970s, the future of Vienna was planned as usual at that time with highways, large garages, subways to replace the annoying streetcars and without bicycle traffic. However, with the demolition of the Florianikirche in 1965, a landmark of the 5th district, in order to make more room for the car, an awareness arose among the population, of the threat to the city by this means of transport. This had consequences. When the motorway plans were stopped in 1972, a new traffic concept had to be worked out. The practical application of the principles elaborated there leads to a sustainable transport policy and to the reversal of trends in the choice of means of transport. Between 1993 and 2015, the share of car trips was reduced from 40% to 27% and the share of trips made by public transport was increased from 29% to 39%. This was prompted by citizen resistance to a city of freeways and by politicians who were willing to learn. Instead of plans for highways, the city is making plans to reclaim public space for nature. However, recent developments show that successes can lead to a relapse into old mistakes.
Interplay between Platelet Dysfunction and Vascular Thrombosis in Traumatic Injury
Authors: Ogweno Gordon , Murungi Edwin
Published: July 2023

Platelets halt bleeding accompanying traumatic injury by performing primary hemostasis to repair vascular leakage at injury sites. In trauma individuals, ex vivo platelet function tests often indicate impairment despite normal count. Moreover, incubation of platelets from normal non-traumatized individuals with plasma from trauma victims demonstrates impairment suggesting association with factors in circulation. Notably, not all trauma victims die from hemorrhage. Despite laboratory evidence of dysfunction, thrombotic vascular occlusions are persistent in trauma survivors as corroborated by postmortem findings from victims who die. The time course of platelet reactions post-traumatic injury, that is, the transition from states favoring bleeding to those that facilitate thrombosis is still unclear. Of the several terminologies describing platelet behavior with regards to injury, including hyporeactivity, anergy, exhaustion, and maladaptive states, few have focused on platelet-platelet interactions. It is increasingly becoming clear that platelet interaction with injured endothelium is a probable missing link in the mechanistic explanation of vascular thrombosis post-traumatic injury. This postulate is supported by evidence of increased adhesive protein, von Willebrand factor, and released from injured endothelium. In all, this potentially explains the suboptimal response to anticoagulants or antiplatelets post-trauma. This chapter will review current knowledge on platelet functions in relation to vascular thrombosis post-trauma, the time course, mechanistic hypothesis, and response to therapeutic interventions and clinical outcomes.

Published: July 2023

Our modern world presents us with ever new challenges that lead to new solutions in all aspects of our lives. Innovation is also evident in our social arrangements, which, similar to the introduction of a new product to the market, entails strong marketing activities in order to be success. Social innovation combined with a social marketing school can bring about very effective social change. This study presents a social innovation that can serve as a pilot project in the field of health promotion. This pilot project is built on the model of holistic health consciousness and responsibility which is a special health promotion and primary prevention example. Within the program, health promotion centers will be established in four locations (Budapest, Miskolc, Szikszó, and Szeged), where natural ingredients and modern technological tools will provide personalized services for primary and secondary prevention and population health promotion.
Anthropocene, Capitalocene, Plantationocene, Necrocene, or Chthulhucene. How to interpret the Environmental crisis

Numerous crises that follow and intersect with each other generated the complexity of our time. Environmental, Social, and Economic effects are spread out on a local and global scale. What is the main characteristic of the crisis of our time? Is our time characterized by an invisible climate crisis accentuated by the hoarding of global natural resources, or the crisis we are experiencing is of an economic and military nature and leads us to rethink the economic and cultural models characterized by the forces of domination of our time? How do the multiple crises on social aspects manifest themselves within local communities? What can be a synthesis of the period we are experiencing under the fractures that the inhabitants of Gaia, the protagonists of this time, are called to mend? This article proposes an analysis of the main phenomena that are characterizing the twenty-first century, following the traces of the structures of domination and power inherited from the previous centuries, but which are already conducting humanity towards a new geological, the Anthropocene. This paper explores the interdependence between ecosystems, climate, biodiversity, and the human sciences to understand the need and urgency to stay within the relative threshold of 1.5° global temperature to ensure human survival.

Da die elektrochemische Umwandlung von CO2 als Schlüsseltechnologie im Kampf gegen den Klimawandel betrachtet wird, werden erhebliche Maßnahmen eingesetzt um ihre Entwicklung zu beschleunigen. Der Vorteil der CO2 Elektrolyse bei niedrigen Temperaturen im Gegensatz zu Hochtemperatur‐elektrolyseuren liegt in der Möglichkeit zur direkten Umsetzung von CO2 zu technisch relevanten Chemikalien. Die Niedertemperatur‐CO2‐Elektrolyse ist jedoch nur bei hoher Effizienz und Stabilität wirtschaftlich rentabel. Obwohl die verwendeten Zelldesigns Ähnlichkeiten mit den etablierten Brennstoff‐ oder auch den weiter entwickelten Wasser‐Elektrolyse‐Zellen aufweisen, müssen verschiedene Designaspekte und einzelne Komponenten adaptiert werden. Aufgrund der Komplexität des Gesamtsystems werden in der Entwicklung oftmals nur einzelne Zellkomponenten optimiert, ohne dass etwaige Einflussfaktoren, die im Zusammenspiel mit anderen Bestandteilen auftreten, berücksichtigt werden. Dass eine ganzheitliche Systembetrachtung bei der Optimierung von Niedertemperatur‐CO2‐Elektrolyseuren notwendig ist, zeigt die Betrachtung des Einflusses von Eisenionen auf die Gesamtzelle deutlich, da nur so bspw. Kreuzkontaminierung gemieden werden kann. Da Eisenionen (Fe) als Verunreinigung omnipräsent sind, wurde ihr Einfluss auf einzelne Zellkomponenten schon vielfach untersucht. Die Zugabe von Eisen erhöht die Aktivität von Nichtedelmetallanoden, gleichzeitig aber tritt eine Verschlechterung der Kathodenaktivität ein und der Membranabbau wird katalysiert. Im Folgenden stellen wir anhand bestehender Literatur, die sich meist auf einzelne Komponenten fokussiert, den Einfluss von Fe‐Spezien in der CO2 Elektrolyse‐Zelle ganzheitlich dar. Hierbei wird ersichtlich, dass das Zusammenspiel zwischen den einzelnen Bestandteilen bei der Zelloptimierung berücksichtigt werden muss.

The first RNA category of the Critical Assessment of Techniques for Structure Prediction competition was only made possible because of the scientists who provided experimental structures to challenge the predictors. In this article, these scientists offer a unique and valuable analysis of both the successes and areas for improvement in the predicted models. All 10 RNA‐only targets yielded predictions topologically similar to experimentally determined structures. For one target, experimentalists were able to phase their x‐ray diffraction data by molecular replacement, showing a potential application of structure predictions for RNA structural biologists. Recommended areas for improvement include: enhancing the accuracy in local interaction predictions and increased consideration of the experimental conditions such as multimerization, structure determination method, and time along folding pathways. The prediction of RNA–protein complexes remains the most significant challenge. Finally, given the intrinsic flexibility of many RNAs, we propose the consideration of ensemble models.

Published: July 2023

Background

Minerals play vital roles in physiologic processes. Calcium, phosphorus and magnesium are common minerals. Secretion, absorption and homeostasis of these minerals are affected by associations between the active vitamin D and parathyroid hormone (PTH).

Objective

The aim of this study was to assess concentrations of vitamin D, PTH and minerals, such as calcium, phosphorus and magnesium in horse sera, as well as associations of these values with lameness in horses. In the references, the reasons for lameness can be deficiency and imbalance of minerals, and clinical observations also confirm this and there is still not enough information regarding the relationship between mineral imbalance and lameness of horses. The prominent forms of lameness include navicular syndrome, back pain, splints, ring bone, side bone, non‐infectious arthritis and bucked shins. Deficiency and inadequacy of calcium, phosphorous and magnesium have been regarded as predisposing and aggravating factors of the aforementioned diseases.

Materials and methods

This cross‐sectional study was carried out on 60 horses, including 30 lame and 30 healthy adult horses, summer to fall 2021. Levels of calcium, phosphorus, magnesium, vitamin D and PTH were assessed in sera using automatic analyser, atomic absorption spectroscopy and commercially available kits.

Results

The average level of calcium was higher healthy horses than lame horses in the two seasons (p < 0.001). The average level of inorganic phosphorus in horses was higher in summer than autumn (p < 0.001). The mean magnesium concentration in healthy horses was greater than lame horses in the two seasons (p < 0.01). In this study, the mean PTH concentration in healthy horses was lower in fall than summer (p < 0.05).

Conclusion

The low average levels of calcium and magnesium in lame horses in the two seasons indicate critical roles of calcium and magnesium in the normal function of the horse musculoskeletal system as well as prevention of lameness.
