Mechanical wear and oxidative degradation analysis of retrieved ultra high molecular weight polyethylene acetabular cups.

The number of revision joint replacements has been increasing substantially over the last few years. Understanding their failure mechanism is extremely important for improving the design and material selection of current implants. This study includes ten retrieved and four new mildly cross-linked ultra-high molecular weight polyethylene (UHMWPE) acetabular liners. Among them, most of the prostheses (n = 5) were reported to be revised and replaced due to aseptic loosening, followed by painful joint (n = 2), dislocation (n = 1), intra articular ossification (n = 1), combination of wear (liner) and osteolysis (stem) (n=1). Surface deviations (wear, material inflation and roughness), oxidative degradation and change of material properties were measured using micro-computed tomography (micro-CT) scan, 3D laser scanning microscopy, raman spectroscopy and nanoindentation, respectively. Prostheses having eccentric worn areas had much higher linear wear rates (228.01 ± 35.51µm/year) compared to that of centrically worn prostheses (96.71 ± 10.83µm/year). Oxidation index (OI) showed similar trends to the surface penetration depth. Among them, sample 10 exhibited the highest OI across the contact area and the rim of the cup liner. It also had the lowest hardness/elasticity ratio. Overall, wear and creep, oxidative degradation and reduced hardness/elasticity ratio all contributed to the premature failure of the UHMWPE acetabular cup liners.

Determination of sensitivity and thermal efficiency in laser assisted metal-plastic joining by numerical simulation

Laser-assisted joining of plastics and metals requires the formation of a melting layer in the thermoplastic material, which enables the wetting and the penetration of the metal surface. In this paper, a generally valid description of the melting layer is given based on material-specific temperatures and numerical simulation. Furthermore, the sensitivity of the melting layer to process parameters, material properties and geometrical parameters is provided. Based on these results, the thermal efficiency of the process was examined depending the major factors metal thickness and absorbed laser beam power.

Area-Averaged Transmitted Power Density at Skin Surface as Metric to Estimate Surface Temperature Elevation

In the international guidelines/standards for human protection, the specific absorption rate (SAR) is used as a metric to prevent excessive surface temperature elevation at frequencies up to 3 or 10 GHz. Above that transition frequency, including the frequency region assigned to 5th generation wireless communication systems, an area-averaged incident power density on human body surface is used as the physical quantity to specify the restrictions on human exposure to electromagnetic fields. However, the incident power density is an external physical quantity, resulting in frequency-dependent temperature elevation, which is attributable to frequency-dependent variations in the reflection coefficient at the skin surface and energy penetration depth into tissue. In this paper, we discuss analytically and computationally the effectiveness of the transmitted power density (TPD) at the skin as a new metric to estimate the steady-state skin temperature elevation above the transition frequency. We also consider simplified models for uniform and Gaussian beam patterns and the analytical solutions to the bioheat equation for an one-dimensional model, which are in good agreement with numerical solutions. These show that the TPD provides an excellent estimate of skin temperature elevation through the millimetre-wave band (30-300 GHz) and a reasonable and conservative estimate down to 10 GHz, whereas the SAR is a good metric below 3 GHz. Computational results for the dipole and patch antenna arrays demonstrated that the one-dimensional analysis is conservative metric as compared with the TPD averaged over the area of 4 cm2 (2-cm square). Considering extreme cases, averaging area smaller than 4 cm2 is needed above 30 GHz for beam exposure with small diameters. Finally, we consider the choice of averaging area as related to peak temperature increases for small beams. For extremely small exposure areas, limits on peak power density may be needed.

Contact mechanics of isotactic polypropylene: Effect of pre-stretch on the frictional response

Polymers are increasingly used in applications where relative moving parts are in contact. The dissipation of energy due to friction, i.e. heat production, reduces a product's lifetime significantly. Since in processing often an extrusion or injection moulding step is used in product formation, the induced anisotropic microstructure leads to a spatial variation of mechanical properties, for example frictional resistance. In this work we compare the scratch response of isotropic isotactic polypropylene (iPP) to the response of various oriented iPP systems. Subjected to single-asperity contact with a rigid diamond, the surface penetration and lateral force are measured. For various combinations of applied normal load and sliding velocity, the surface penetration and lateral force are measured. Optical profilometry measurements are used to explain the (large) differences in residual scratch profile between tests performed in the direction parallel and transverse to the orientation direction, respectively. As the anisotropy increases with the amount of orientation, both the maximum tensile stress and the strain hardening increase substantially. The penetration depth, for oriented systems governed by the transverse viscoelasticity and yield stress, is comparable for all loading angles and decreases with increasing amount of orientation. The direction of lowest frictional resistance is shown to be the direction parallel to the oriented crystals. The combination of decreasing global deformation and friction reduction as a result of pre-stretch decelerates strain localization, therewith delaying crack initiation which eventually leads to abrasive wear. Along with that, the substantial amount of elastic recovery after scratching in the transverse direction is related to the pre-tension of the perpendicular crystal network.

Thermo‐mechanical modeling of turbine blades taking into account structural defects

AbstractIn turbine blades of aero‐engines typical defects are cracks due to high mechanical and thermal loads. The extended finite element method (XFEM) is used for simulations of fracture mechanics problems with cracks. Discontinuities in the displacement and temperature field are allowed and the crack opening displacement and crack tip stress field are reproduced accurately. Since crack closure and non‐physical penetration of the crack surfaces may occur under certain load conditions, it becomes necessary to enforce the non‐penetration condition for crack surfaces. This contact formulation is assumed to be frictionless. The node‐to‐segment approach proposed in [3] is extended to ten‐node tetrahedral elements with quadratic shape functions.

Stabilization of drifting sands using micro silica-lime-clay mixture as a mulch

Providing durable mulches with improved resistance using cheap materials in order to stabilize drifting sands is very important. Micro silica is one of these materials which in combination with lime and clay can offer resistant mulches. In the present study, different mixtures of micro silica-lime-clay were used as mulches. In all treatments, the amounts of 200 g clay and 10 g lime were used as the basic composites of mulches and micro silica was added at 0, 1, 5, 10, 15, and 20% of clay dry weight. Generally, six different mixtures were obtained at three replicates and four parameters including surface soil shear strength (SS), penetration resistance (PR), soil losses (SL), and threshold friction velocity (V) were measured on samples after 7 and 60 days. Results showed that the application of micro silica in clay-lime mixture increased SS, PR, and V significantly, so that the increase in measured parameters depended on the applied micro silica rates. The more the micro silica rates, the greater decrease in soil erosion, so that the soil losses at a wind speed of 15 ms−1 decreased 100 times at the rates of 5, 10, 15, and 20% of micro silica and no losses were observed at these rates in comparison with control situation (0%). More improvements occurred in the mentioned properties of mulches during time. The application of 200 g clay, 10 g lime, and 20 g micro silica after 60 days was the best composition for improving the studied mulches resistance.

Large area imaging of forensic evidence with MA-XRF

This study introduces the use of macroscopic X-ray fluorescence (MA-XRF) for the detection, classification and imaging of forensic traces over large object areas such as entire pieces of clothing and wall paneling. MA-XRF was sufficiently sensitive and selective to detect human biological traces like blood, semen, saliva, sweat and urine on fabric on the basis of Fe, Zn, K, Cl and Ca elemental signatures. With MA-XRF a new chemical contrast is introduced for human stain detection and this can provide a valuable alternative when the evidence item is challenging for conventional techniques. MA-XRF was also successfully employed for the chemical imaging and classification of gunshot residues (GSR). The full and non-invasive elemental mapping (Pb, Ba, Sr, K and Cl) of intact pieces of clothing allows for a detailed shooting incident reconstruction linking firearms and ammunition to point of impact and providing information on the shooting angle. In high resolution mode MA-XRF can even be used to provide information on the shooting order of different ammunition types. Finally, by using the surface penetration of X-rays we demonstrate that the lead signature of a bullet impact can be easily detected even if covered by multiple layers of wall paint or human blood.

Locally Advanced Colorectal Cancer: True Peritoneal Tumor Penetration is Associated with Peritoneal Metastases

BackgroundFindings show T4 colorectal cancer (CRC) to be a risk factor for the development of peritoneal metastases (PM). Heterogeneity regarding peritoneal involvement of T4 tumors might explain the wide range of reported PM incidences (8–50%). Hyperplastic and mesothelial inflammatory reactions complicate evaluation of the exact primary tumor involvement of the peritoneal layer. This retrospective cohort study aimed to assess the association between either inflammatory peritoneal reaction or peritoneal involvement of the primary tumor and the risk of PM.MethodsSince 2010, pathologists at UZ Leuven have systematically categorized peritoneal involvement in peritoneal reaction with tumor less than 1 mm from the peritoneal surface or true peritoneal penetration. All patients undergoing resection of CRC between January 2010 and July 2013 who fulfilled either of these pathologic criteria were included in this study.ResultsThe study enrolled 159 CRC patients. Peritoneal reaction with tumor less than 1 mm from the peritoneal surface was present in 43 patients and true peritoneal penetration in 116 patients. Overall, 29 patients (18%) had synchronous PM, and 30 patients (23%) had metachronous PM. In the multivariable analysis, true peritoneal penetration, in contrast to peritoneal reaction with tumor less than 1 mm from the peritoneum, was associated with greater risk of PM (odds ratio [OR], 2.518; range, 1.038–6.111; p = 0.041) and lymph node involvement (N1: OR, 1.572; range, 0.651–3.797 vs N2: OR, 4.046; range, 1.549–10.569; p = 0.014).ConclusionHistologically confirmed true peritoneal penetration by CRC, rather than inflammatory peritoneal reaction constitutes a high risk for PM. With evolving treatment strategies that aim to treat PM in an earlier phase, identification of high-risk patients becomes highly important clinically.

Evaluation of In-Situ NOx Removal Efficiency of Photocatalytic Concrete in Expressways

In areas of high-volume traffic, such as the proximities of expressways in large urban areas, the amounts of nitrogen oxides (NOx) emitted into the atmosphere significantly contribute to air pollution. As NOx gas is a major cause of smog and acid rain, this pollutant is considered to be particularly harmful, and therefore, increasing attention has been focused worldwide on the elimination of NOx from the air. Titanium dioxide (TiO2), a photocatalytic reaction material, is particularly effective in the removal of NOx. As the solar photocatalytic reaction of TiO2 is the mechanism that eliminates NOx, the TiO2 in concrete road structures needs to be exposed to the ultraviolet rays (UV) of sunlight to be activated. Generally, TiO2 concrete is produced by replacing a portion of the concrete binder with TiO2. However, a considerable amount of the TiO2 in the concrete is not exposed to either the air pollutants or the UV. Therefore, as an alternative method, surface penetration agents are used to add TiO2 to the surface of the concrete structure. This study aims to evaluate the in-situ NOx removal efficiency of the TiO2 penetration method in a field application. Accordingly, the TiO2 penetration method was tested on the retaining wall of the Gyeongbu expressway in Korea. The results of this study indicated that the quantity of sunlight influenced the NOx removal efficiency rate. Furthermore, it was c that the TiO2 penetration method can be an alternative to the existing TiO2 concrete, which produced by replacing a portion of the concrete binder with TiO2, for removing NOx gas from the air.

Penetration length-dependent hot electrons in the field emission from ZnO nanowires

Abstract In the framework of field emission, whether or not hot electrons can form in the semiconductor emitters under a surface penetration field is of great concern, which will provide not only a comprehensive physical picture of field emission from semiconductor but also guidance on how to improve device performance. However, apart from some theoretical work, its experimental evidence has not been reported yet. In this article, the field penetration length-dependent hot electrons were observed in the field emission of ZnO nanowires through the in-situ study of its electrical and field emission characteristic before and after NH3 plasma treatment in an ultrahigh vacuum system. After the treatment, most of the nanowires have an increased carrier density but reduced field emission current. The raised carrier density was caused by the increased content of oxygen vacancies, while the degraded field emission current was attributed to the lower kinetic energy of hot electrons caused by the shorter penetration length. All of these results suggest that the field emission properties of ZnO nanowires can be optimized by modifying their carrier density to balance both the kinetic energy of field induced hot electrons and the limitation of saturated current under a given field.

The Study of Growth of Calogaya sp. PLM8 on Cyrus the Great’s Tomb, UNESCO World Heritage Site in Iran

The tomb of Cyrus the Great, the most important monument in Pasargadae, has been listed as a world heritage site by UNESCO. Like many other stone monuments, the tomb has been affected by the colonization of microbial communities, especially lichens that were subjected to physical elimination in 2006. In the present study, recolonization of Calogaya sp. PLM8, a crustose lichen and its role in biodeterioration of Cyrus the Great tomb have been evaluated. Calogaya sp. PLM8 commonly colonized on this monument with significant distribution in the different facades. The interface of Calogaya sp. PLM8 with the underlying substrate has been investigated using the periodic acid-Schiff staining, scanning electron microscopy and energy-dispersive spectroscopy techniques. The results showed that both colonization of the lichen on the surface and symbiont cells penetration into the stone had caused extensive physical and chemical biodeterioration of the substrate. Besides the presence of the symbionts in the endolithic niches, other lithobiont microorganisms have been detected inside the stones. The presence of these endolithic microorganisms seems to be conditioned by the presence of the epilithic lichen thallus and its effects on the formation of microenvironments in the colonized stone. The lithobiont communities interact both geophysically and geochemically with the lithic substrate, inducing biodeterioration alteration in the tomb of Cyrus the Great.

Qualification of Chemically Bonded Sand Systems Using a Casting Trial for Quantifying Interfacial Defects

Chemically bonded sand cores and molds are an important part of metal casting technology and their interaction with metal (mold–metal interface) is of great interest. Currently, the metal casting industry places a strong emphasis on near-net-shape and thin wall castings, while simultaneously maintaining increasingly stringent dimensional reproducibility requirements. To efficiently and cost effectively accomplish this task, it becomes crucial to ensure or “qualify” high-quality performance at the mold–metal interface. The thermal distortion test (TDT) was used in published American Foundry Society (AFS) studies as a laboratory technique to determine the presence of anomalies and for measuring distortions in chemically bonded sand binder systems. However, these laboratory tests focus purely on sand binder system behavior, without considering the effects of actual mold–metal interfaces. While the TDT provides valuable insight, it is unable to ensure castings will be free (or contain an acceptable amount) of specific defects. Therefore, to maximize casting quality and efficiency, it becomes imperative to incorporate casting trials into a foundry’s quality control system. This will allow the occurrence of potential casting defects to be observed at the mold–metal interface. This paper presents a casting trial technique that provides three specific benefits to foundry quality control systems. First, these trials will qualify sand binder systems against a specific casting surface defect(s), such as surface roughness, veins, penetration, cuts, washes, and erosion. Second, these casting trials are implemented under constant casting, mold, process, and design parameters. This allows the casting trial(s) to provide diagnostic information (i.e., if a specific defect occurs when using a qualified sand binder system, the cause cannot be related to the sand binder system). Third, the casting trial technique provides new opportunities for data analysis and deeper system understanding. Specifically, results in this paper identify the possibility of a potential relation between TDT data (e.g., anomalies and distortions) and actual casting trial data (e.g., defects).

Studies on the Behavior of Eucalyptol and Terpinen-4-ol—Natural Food Additives and Ecological Pesticides—in Model Lipid Membranes

Effective application of the essential oils requires detailed exploration of their mechanism of action and the origin of diverse activity of their components. In this work, the influence of eucalyptol and terpinen-4-ol on artificial membranes was studied to verify whether the differences in the activity of these compounds are related to their effect on membranes. The properties of monolayers formed from structurally different lipids in the presence of terpenes were examined based on the results of the surface pressure-area measurements, penetration studies, and Brewster angle microscopy experiments. Both compounds were able to incorporate into the membrane and alter lipid/lipid interactions, making the monolayer less stable and more fluid. These effects were determined by monolayer composition (but not by its condensation per se) and the resulting rheological properties and were stronger in the presence of terpinen-4-ol. These findings confirm the hypothesis that differences in the antimicrobial potency of these terpenes are membrane-related, and membrane composition may determine their selectivity.

Non-invasive three-dimensional imaging of Escherichia coli K1 infection using diffuse light imaging tomography combined with micro-computed tomography.

In contrast to two-dimensional bioluminescence imaging, three dimensional diffuse light imaging tomography with integrated micro-computed tomography (DLIT-μCT) has the potential to realise spatial variations in infection patterns when imaging experimental animals dosed with derivatives of virulent bacteria carrying bioluminescent reporter genes such as the lux operon from the bacterium Photorhabdus luminescens. The method provides an opportunity to precisely localise the bacterial infection sites within the animal and enables the generation of four-dimensional movies of the infection cycle. Here, we describe the use of the PerkinElmer IVIS SpectrumCT in vivo imaging system to investigate progression of lethal systemic infection in neonatal rats following colonisation of the gastrointestinal tract with the neonatal pathogen Escherichia coli K1. We confirm previous observations that these bacteria stably colonize the colon and small intestine following feeding of the infectious dose from a micropipette; invading bacteria migrate across the gut epithelium into the blood circulation and establish foci of infection in major organs, including the brain. DLIT-μCT revealed novel multiple sites of colonisation within the alimentary canal, including the tongue, oesophagus and stomach, with penetration of the non-keratinised oesophageal epithelial surface, providing strong evidence of a further major site for bacterial dissemination. We highlight technical issues associated with imaging of infections in new born rat pups and show that the whole-body and organ bioburden correlates with disease severity.

Essential oils as food eco-preservatives: Model system studies on the effect of temperature on limonene antibacterial activity

Antimicrobial properties of essential oils predestine these substances to be used as ecological food preservatives. However, their activity is determined by variety of factors among which external conditions and food properties are highly important. Herein the influence of limonene on artificial membranes was studied to verify the effect of temperature on the incorporation of this compound into model bacterial membrane. The investigations were done on lipid monolayers and the experiments involved the surface pressure-area measurements, penetration studies and Brewster Angle Microscopy analysis. It was found that limonene incorporates into lipid monolayers causing their fluidization. However, the magnitude of alterations depends on limonene concentration, model membrane composition and, for a given composition, on system condensation. Moreover, the influence of limonene is stronger at lower temperatures and, in the light of collected data, this may be a consequence of strong volatility and evaporation of limonene increasing with temperature.

Fungicide Efficacy Against Botrytis cinerea at Different Positions on Grape Shoots

Fungicide efficacy at different positions on grape shoots was determined on vinelets inoculated with Botrytis cinerea. To ensure proper fungicide coverage, vinelets (table grape cultivar Dauphine, wine grape cultivar Merlot noir), prepared from cuttings, were sprayed in a spray chamber at the recommended dosages with iprodione, pyrimethanil, cyprodinil/fludioxonil and fenhexamid. Vinelets for the control treatment were left unsprayed. After 24 h the vinelets were dusted with dry, airborne conidia in a settling ower to reduce the sporadic occurrence of the pathogen on shoots and incubated for 24 h at high relative humidity (±93 % ) to promote infection. Fungicide efficacy was determined by observing intact vinelets for symptom expression at nodes, internodes, leaf blades, petioles and inflorescences, and by determining surface colonisation (shoots left unsterile) and penetration (surfacedisinfested shoots) by isolation studies. Symptoms of B. cinerea decay did not develop on sprayed and unsprayed vinelets that were kept in dry chambers during the 2-week observation period. The pathogen, however, developed from the isolated parts. On the unsprayed vinelets for both cultivars B. cinerea incidences recorded on two media and the two sterility regimes were significantly higher on leaf blades than on the petioles, shoot pieces and inflorescences. The isolation studies showed that the different fungicides were highly and nearly equally efficient in reducing superficial B. cinerea and latent infection at the various positions. In the case of leaf blades B. cinerea incidence was significantly reduced by each fungicide on both cultivars. This was not the case for the other parts, which yielded B. cinerea at low incidences under the two sterility regimes. The study showed that the fungicides used in this study, if applied properly to shoots at the pre-bloom stage, should effectively reduce the amount of B. cinerea in leaves and completely prevent the infection of nodes, internodes and inflorescences.

Fitness on Grape Berries of Botrytis cinerea Isolates Belonging to Different Dicarboximide Sensitivity Classes

Seasonal fluctuations in the frequency of dicarboximide-resistant Botrytis cinerea isolates in Western Cape vineyards suggest a reduced fitness of these isolates. In this study fitness of sensitive, ultra-low-level and low-level dicarboximide-resistant isolates of B. cinerea were compared on grape berries. Conidia were dispersed as single cells on berry surfaces from airborne inoculum in a settling tower or deposited as clusters in water droplets. Investigations were conducted at two potential infection courts on dicarboximide treated and untreated berries, namely the intact cuticle and wounds. Surface sterilisation, isolation and freezing techniques were used to determine surface colonisation and penetration by airborne inoculum. Decay incidence, severity and sporulation incidence were determined following inoculation with conidial clusters. The different tests indicated that germlings of dicarboximide-sensitive and -resistant isolates had similar surface-colonising abilities of dicarboximide-free berries. However, sensitive strains penetrated significantly more often. Fitness decreased with an increase in the level of dicarboximide resistance. Iprodione caused a drastic disturbance in the ratio of different dicarboximide sensitivity classes that occupied the berry surface and allowed the development of germlings of predominantly resistant isolates, but with few successful infections. Significantly higher levels of infection and proliferation of dicarboximide-resistant isolates on sprayed or unsprayed berries were facilitated by wounding or the termination of host resistance (freezing). According to these findings, these modes of infection should not contribute to a gradual build-up of inoculum of either dicarboximide-sensitive or -resistant isolates. Trends by airborne conidia described here suggest that another primary infection event in the vineyard, most likely floral infection and subsequent debris colonisation, should largely regulate the dynamics between dicarboximide-sensitive and -resistant isolates in B. cinerea populations on grapevine.

Shallow Water Measurements Using a Single Green Laser Corrected by Building a Near Water Surface Penetration Model

To reduce the size and cost of an integrated infrared (IR) and green airborne LiDAR bathymetry (ALB) system, and improve the accuracy of the green ALB system, this study proposes a method to accurately determine water surface and water bottom heights using a single green laser corrected by the near water surface penetration (NWSP) model. The factors that influence the NWSP of green laser are likewise analyzed. In addition, an NWSP modeling method is proposed to determine the relationship between NWSP and the suspended sediment concentration (SSC) of the surface layer, scanning angle of a laser beam and sensor height. The water surface and water bottom height models are deduced by considering NWSP and using only green laser based on the measurement principle of the IR laser and green laser, as well as employing the relationship between NWSP and the time delay of the surface return of the green laser. Lastly, these methods and models are applied to a practical ALB measurement. Standard deviations of 3.0, 5.3, and 1.3 cm are obtained by the NWSP, water-surface height, and water-bottom height models, respectively. Several beneficial conclusions and recommendations are drawn through the experiments and discussions.

Correlation of Periodontal Disease With Inflammatory Arthritis in the Time Before Modern Medical Intervention.

Controversy exists regarding possible correlation of periodontal disease with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Confounding factors may relate to stringency of inflammatory disease diagnosis and the effect of therapeutic intervention for RA on periodontal disease. These factors are investigated in this study. Forty-five individuals with documented RA (n = 15), spondyloarthropathy (n = 15), and calcium pyrophosphate deposition disease (CPPD) (n = 15), from the Hamann-Todd collection of human skeletons compiled from 1912 to 1938, and 15 individuals contemporarily incorporated in the collection were examined for tooth loss, cavity occurrence, average and maximum lingual and buccal depth of space between tooth and bone, periosteal reaction, serpentine bone resorption, abscess formation, and root penetration of the bone surface and analyzed by analysis of variance. Tooth loss was common, but actual number of teeth lost, cavity occurrence, average and maximum lingual and buccal depth of space between tooth and bone, periosteal reaction, serpentine grooving surrounding teeth (considered a sign of inflammation), abscess formation, and root exposure (penetration of bone surface) were indistinguishable among controls and individuals with RA, spondyloarthropathy, and CPPD. Although many factors can affect periodontal disease, presence of inflammatory arthritis does not appear to be one of them. The implication is that dental disease was common in the general population and not necessarily associated with arthritis, at least before the advent of modern rheumatologic medications. As specific diagnosis did not affect prevalence, perhaps current prevalence controversy may relate to current intervention, a subject for further study.

Assessment of soil quality index for wheat and sugar beet cropping systems on an entisol in Central Anatolia.

The sustainable use of agricultural lands is significantly affected by the implemented management and land processing methods. In sugar beet and wheat cropping, because the agronomic characteristics of plants are different, the tillage methods applied also exhibit significant variability. Soil quality concept is used, as a holistic approach to determining the effects of these applications on the sustainable use of soil. Agricultural soil quality evaluation is essential for economic success and environmental stability in rapidly developing regions. At present, a variety of methods are used to evaluate soil quality using different indicators. This study was conducted in one of the most important irrigated agriculture areas of Çumra plain in Central Anatolia, Turkey. In the soil under sugar beet and wheat cultivation, 12 soil quality indicators (aggregate stability (AS), available water capacity (AWC), surface penetration resistance (PR0-20), subsurface penetration resistance (PR20-40), organic matter (OM), active carbon (AC), potentially mineralizable nitrogen (PMN), root health value (RHV), pH, available phosphorus (AP), potassium (K), and macro-micro elements (ME) (Mg, Fe, Mn, and Zn)) were measured and scored according to the Cornell Soil Health Assessment (CSHA) and the Soil Management Assessment Framework (SMAF). The differences among 8 (AS, AWC, PR0-20, PR20-40, AC, PMN, AP, and ME) of these 12 soil quality characteristics measured in two different plant cultivation were found statistically significant. The result of the soil quality evaluation with scoring function in the examined area revealed a soil quality score of 61.46 in the wheat area and of 51.20 in the sugar beet area, which can be classified as medium and low, respectively. Low soil quality scores especially depend on physical and biological soil properties. Therefore, improvement of soil physical and biological properties with sustainable management is necessary to enhance the soil quality in the study area soils.
