Influence of Storage Containers and Seed Pelleting on Seed Quality in Brinjal (Solanum melongena L.) during Storage
The experiment was conducted using brinjal hybrid seeds cv. Arka Navneet. Seeds were pelleted with Bavistin, ZnSO4, MnSO4, DAP and Arappu leaf powder and stored in paper and polyethylene bags under ambient conditions for 12 months. Among the seed pelleting treatments, seeds pelleted with Bavistin (0.1%) followed by Albezia amara leaf powder (250 g/kg) resulted in minimum quantitative losses with better seed quality parameters. The seeds stored in polyethylene (700 gauges) bags maintained better seed quality parameters with less quantitative losses in comparison with seeds stored in paper bags throughout the storage period. In the interaction, effect of seeds pelleted with Bavistin and stored in polyethylene bag followed by Albezia amara leaf powder and stored in polyethylene bag revealed higher values for all the positive quality parameters when compared to other interaction effects throughout the storage period
Limb position influences component orientation in Oxford mobile bearing unicompartmental knee arthroplasty: an experimental cadaveric study
Aims
The mobile bearing Oxford unicompartmental knee arthroplasty (OUKA) is recommended to be performed with the leg in the hanging leg (HL) position, and the thigh placed in a stirrup. This comparative cadaveric study assesses implant positioning and intraoperative kinematics of OUKA implanted either in the HL position or in the supine leg (SL) position.
Methods
A total of 16 fresh-frozen knees in eight human cadavers, without macroscopic anatomical defects, were selected. The knees from each cadaver were randomized to have the OUKA implanted in the HL or SL position.
Results
Tibial base plate rotation was significantly more variable in the SL group with 75% of tibiae mal-rotated. Multivariate analysis of navigation data found no difference based on all kinematic parameters across the range of motion (ROM). However, area under the curve analysis showed that knees placed in the HL position had much smaller differences between the pre- and post-surgery conditions for kinematics mean values across the entire ROM.
Conclusion
The sagittal tibia cut, not dependent on standard instrumentation, determines the tibial component rotation. The HL position improves accuracy of this step compared to the SL position, probably due to better visuospatial orientation of the hip and knee to the surgeon. The HL position is better for replicating native kinematics of the knee as shown by the area under the curve analysis. In the supine knee position, care must be taken during the sagittal tibia cut, while checking flexion balance and when sizing the tibial component
Secure Effective Detection Approach for Detecting Malicious Facebook Application
Third-party apps square measure a significant reason for the recognition and addictiveness of Facebook. Sadly, hackers have accomplished the potential of exploitation apps for spreading malware and spam. As we discover that a minimum of thirteen of apps in our knowledge square measure malicious. So far, the analysis community has targeted on detective work malicious posts and campaigns. During this paper, we have a tendency to raise the question: Given a Facebook application, will we have a tendency to confirm if it's malicious? Our key contribution is in developing FRAppE?Facebook?s Rigorous Application authority the primary tool targeted on detective work malicious apps on Facebook. To develop FRAppE, we have a tendency to use info gathered by perceptive the posting behavior of 111K Facebook apps seen across 2.2 million users on Facebook. First, we have a tendency to establish a collection of options that facilitate U.S. distinguish malicious apps from benign ones. For instance, we discover that malicious apps typically share names with different apps, and that they usually request less permission than benign apps. Second, investment these distinctive options, we have a tendency to show that FRAppE will discover malicious apps with ninety nine accuracy
Fingerprint Verification using Steerable Filters”,
ABSTRACT In this paper, fingerprint verification using steerable filters is presented. The existing fingerprint recognition systems are based on minutiae matching. The common fingerprint matching schemes are Correlation-based matching, Minutiae-based matching and Ridge feature -based matching. The minutiae-based matching systems are the most widely used and popular. The minutiae extraction undergoes very critical steps (like binerization, thinning) and which affects on the overall accuracy of the system. Poor ridge structure and the image processing articrafts may introduce spurious minutiae. A frequency selective as well as orientation selective transform like Gabor transform has been used for extracting the texture features. This paper describes a novel approach based on steerable wedge filter. The proposed method is capable of finding the texture features of fingerprint image irrespective to the image quality in terms of average gray level, clarity in the ridges and comparatively with fewer computations
Design and testing of a metering system for fodder seed treatment
Quality of fodder seeds can be maintained by seed treatment for better production and productivity. It refers to the application of specific physical, chemical, or biological agents to the seed prior to sowing in order to suppress, control, or repel pathogens, insects, and other pests that attack seeds, seedlings, or plants. In this study, the efficient seed and chemical metering system for fodder seed treatment was designed which can be used in different seed coating/treatment machine. Seed metering mechanism was calibrated mechanically and manually at four positions (Full, 3/4th, Half, and 1/4th openings). For manual calibration, it was observed between 0.19 kg/s to 1.08 kg/s for Berseem seeds and 0.15 kg/s to 1.00 kg/s for Cowpea seeds. For mechanical calibration, it was observed between 0.24 kg/s to 1.17 kg/s for Berseem seeds and 0.11 kg/s to 1.04 kg/s for Cowpea seeds. Designed system is useful in developing high capacity, efficient and cost effective seed treaters for treatment/coating of fodder seeds as well as other crop seeds
Recurrent Spinal Giant Cell Tumors: A Study of Risk Factors and Recurrence Patterns
Study DesignRetrospective study.PurposeTo highlight risk factors, recurrence patterns and multimodal treatment in management of recurrent giant cell tumors (GCTs).Overview of LiteratureGCTs of the spine are rare and challenging entities. Recurrences are very common and warrant complex management to prevent multiple recurrences. Gross total resection is preferred over subtotal procedures to prevent recurrences. However, resection is associated with morbidity and mortality. Proper understanding of risk factors and a high index of suspicion helps to spot recurrences early and aids in subsequent management.MethodsTen patients (six females, four males) with recurrent GCTs underwent 17 interventions. There were six lesions in the thoracic spine, two in the cervical spine and two in the lumbar spine. Recurrences were managed with preoperative digital subtraction embolization, intralesional curettage and postoperative radiotherapy.ResultsThe average age at intervention was 31.3 years. The average duration of recurrence in patients following index surgery in a tertiary care hospital and surgery elsewhere was 7.3 years and was 40 months, respectively. The minimum recurrence-free interval after the last recurrent surgery was 10 years.ConclusionsOur study reports the largest recurrence-free interval for GCTs. Recurrent GCTs are challenging entities. Understanding of risk factors and meticulous planning is required to prevent recurrences. Intralesional surgery could be a safer and effective modality in managing recurrences
Non-Surgical Management of Cord Compression in Tuberculosis: A Series of Surprises
Study DesignProspective study.PurposeWe present a series of 50 patients with tuberculous cord compression who were offered systematic non-surgical treatment, and thereby, the author proposes that clinico-radiological soft tissue cord compression is not an emergency indication for surgery.Overview of LiteratureSpinal cord compression whether clinical or radiological has usually been believed to be an indication for emergency surgery in spinal tuberculosis.MethodsFifty adults were prospectively studied at our clinic for spinal cord compression due to tuberculous spondylitis, between May 1993 and July 2002. The inclusion criteria were cases with clinical and/or radiological evidence of cord compression (documented soft tissue effacement of the cord with complete obliteration of the thecal sac at that level on magnetic resonance imaging scan). Exclusion criteria were lesions below the conus level, presence of bony compression, severe or progressive neurological deficit (<than Frankel grade C) and children below the age of maturity. All patients were treated with a fixed, methodically applied non-surgical protocol including hospital admission, antitubercular medications, baseline somatosensory evoked potentials and a regular clinico-radiological follow-up.ResultsAt the time of presentation, 10 patients had a motor deficit, 18 had clinically detectable hyper-reflexia and 22 had normal neurology. Forty-seven of the 50 patients responded completely to non-operative treatment and healed with no residual neurological deficit. Three patients with progressive neurological deficit while on treatment were operated on with eventual excellent recovery.ConclusionsRadiological evidence of cord compression and early neurological signs need not be an emergency surgical indication in the management of spinal tuberculosis
Phenotyping Post-COVID Pain as a Nociceptive, Neuropathic, or Nociplastic Pain Condition
Pain after an acute Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19) condition (post-COVID pain) is becoming a new healthcare emergency. Precision medicine refers to an evidence-based method of grouping patients based on their diagnostic/symptom presentation and then tailoring specific treatments accordingly. Evidence suggests that post-COVID pain can be categorized as nociceptive (i.e., pain attributable to the activation of the peripheral receptive terminals of primary afferent neurons in response to noxious chemical, mechanical, or thermal stimuli), neuropathic (i.e., pain associated with a lesion or disease of the somatosensory nervous system and limited to a “neuroanatomically plausible” distribution of the system), nociplastic (i.e., pain arising from altered nociception despite no clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain), or mixed type (when two pain phenotypes co-exist). Each of these pain phenotypes may require a different treatment approach to maximize treatment effectiveness. Accordingly, the ability to classify post-COVID pain patients into one of these phenotypes would likely be critical for producing successful treatment outcomes. The 2021 International Association for the Study of Pain (IASP) clinical criteria and grading system provide a framework for classifying pain within a precision pain medicine approach. Here we present data supporting the possibility of grouping patients with post-COVID pain into pain phenotypes, using the 2021 IASP classification criteria, with a specific focus on nociplastic pain, which is probably the primary mechanism involved in post-COVID pain. Nociplastic pain, which is usually associated with comorbid symptomology (e.g., poor sleep quality, fatigue, cognitive–emotional disturbances, etc.) and is considered to be more difficult to treat than other pain types, may require a more nuanced multimodal treatment approach to achieve better treatment outcomes
Automatic processing, quality assurance and serving of real-time weather data
Recent advances in technology have produced a significant increase in the availability of free sensor data over the Internet. With affordable weather monitoring stations now available to individual meteorology enthusiasts a reservoir of real time data such as temperature, rainfall and wind speed can now be obtained for most of the United States and Europe. Despite the abundance of available data, obtaining useable information about the weather in your local neighbourhood requires complex processing that poses several challenges. This paper discusses a collection of technologies and applications that harvest, refine and process this data, culminating in information that has been tailored toward the user. In this case we are particularly interested in allowing a user to make direct queries about the weather at any location, even when this is not directly instrumented, using interpolation methods. We also consider how the uncertainty that the interpolation introduces can then be communicated to the user of the system, using UncertML, a developing standard for uncertainty representation
Impact of immobilisation and image guidance protocol on planning target volume margins for supine craniospinal irradiation
Background: The setup errors during supine-CSI (sCSI) using single or dual immobilisation (SM, DM) subsets from two institutions were reviewed to determine if DM consistently decreased the required planning target volumes (PTV) margins and to identify the optimal image guidance environments.
Materials and methods: Ours and a sister institutional cohort, each with a subset of SM or DM sCSI and daily 3-dimensional online image verification sets, were reviewed for the cranial and spinal regions translational shifts. Using descriptive statistics, scatter plots and independent sample Mann-Whitney test we compared shifts in each direction for two subsets in each cohort deriving PTV margins (Van Herk: VH, Strooms: St recipes) for the cranial and spinal regions. Three image guidance (IG) protocols were simulated for two regions on the combined cohort with SM and DM subsets to identify the most optimal option with the smallest PTV margin. The IG protocols: 3F, 5F and 5FB where the systematic error correction was done using the average error from the first three, five and in the cranium alone (applied to both the cranium and spine, otherwise) for the first five set-ups, respectively.
Results: 6968 image sets for 179 patients showed DM could consistently reduce the PTV margin (VH/St) for the cranium from 6/5 to 4/3.5 (31.8/30.8%) and 6/4 to 4/3.5 mm (30.5/16.8%) for primary and validation cohort, respectively. Similarly, for the spine it was 10/8.5 to 6/5.5 (38.6/38.4%) and 9/7.7 to 7/6 (21.6/21.4%), respectively. The “5F-IG” resulted in the smallest margins for both the cranial (3 mm) and spinal region (5 mm) for DM with estimated 95% CTV coverage probability.
Conclusion: DM with 5F-IG would significantly reduce the required PTV margins for sCSI
