Forensic radiology in dentistry
No full textRadiography can play an important part in forensic odontology, mainly to establish identification. This may take the precise form of comparison between antemortem and postmortem radiographs. Radiographs may also be taken to determine the age of a minor victim and even help in the assessment of the sex and ethnic group. Comparable radiographs are an essential factor to confirm identification in a mass disaster
A solitary palatal mass
No full textMyoepithelioma is a rare benign neoplasm of major and minor salivary glands, composed almost exclusively of sheets, islands or cords of cells with myoepitheliomal differentiation. Myoepithelioma represents 15% of all salivary glands neoplasm, most commonly occurs in parotid gland. Here, we report a rare case of myoepithelioma of hard palate
Sensitivity of double centrifugation sugar fecal flotation for detecting intestinal helminths in coyotes (Canis latrans)
No full textFecal analysis is commonly used to estimate prevalence and intensity of intestinal helminths in wild carnivores, but few studies have assessed the reliability of fecal flotation compared to analysis of intestinal tracts. We investigated sensitivity of the double centrifugation sugar fecal flotation and kappa agreement between fecal flotation and postmortem examination of intestines for helminths of coyotes (Canis latrans). We analyzed 57 coyote carcasses that were collected between October 2010 and March 2011 in the metropolitan area of Calgary and Edmonton, Alberta, Canada. Before analyses, intestines and feces were frozen at -80 C for 72 hr to inactivate Echinococcus eggs, protecting operators from potential exposure. Five species of helminths were found by postmortem examination, including Toxascaris leonina, Uncinaria stenocephala, Ancylostoma caninum, Taenia sp., and Echinococcus multilocularis. Sensitivity of fecal flotation was high (0.84) for detection of T. leonina but low for Taenia sp. (0.27), E. multilocularis (0.46), and U. stenocephala (0.00). Good kappa agreement between techniques was observed only for T. leonine (0.64), for which we detected also a significant correlation between adult female parasite intensity and fecal egg counts (R-s=0.53, P=0.01). Differences in sensitivity may be related to parasite characteristics that affect recovery of eggs on flotation. Fecal parasitologic analyses are highly applicable to study the disease ecology, of urban carnivores, and they often provide important information on environmental contamination and potential of zoonotic risks. However, fecal-based parasitologic surveys should first assess the sensitivity of the techniques to understand their biases and limitations
zManav: Db2 for z/OS Wellness Monitor
No full textThe zManav, Db2 for z/OS Wellness Monitor, is an AI-driven solution that automates the monitoring and analysis of Mainframe Db2 for z/OS operational logs. The development research addresses the challenge of analyzing complex mainframe syslogs, which are prone to anomalies during high workload periods, disaster recovery, during major mainframe infrastructure h/w and s/w upgrade and maintenance activities.
By leveraging periodic automated reporting from Db2 for z/OS MSTR JESMSLG integrated with graphical visualizations, the zManav streamlined log analysis and enhanced administrative efficiency.
Using Design Science Research method, the author developed an automated syslog parsing and anomaly detection tool-zManav which tailored to Db2 MSTR JESMSGLG logs. The Design Science research method is categorised into five phases.
They are as follows:
(i)Problem and Motivation: Transform humanistic monitoring to AI based monitoring and alerting.
(ii)Objective Definition: Develop a technique to transform logs to structural format for data analytics.
(iii)Design and Development: Using pandas python libraries in Databricks, produce metrics and alerts.
(iv)Demonstration: Demonstrate the metrics in time-series analysis framework using zManav tool.
(v)Communication: Document the research development as Master’s thesis and training to the team.
The AI-driven analysis and monitoring process involved extracting relevant data from Mainframe Db2 system logs and moved to Databricks as text files for Dat analytics using Pandas Data Frame and the processed data is then stored as TSV (Tab Separated Value) format. The resulting metrics using Data analytics, facilitated behaviour analysis by identifying trends associated with selected message IDs and highlighting new message IDs that might require attention.
The zManav not only streamlined the monitoring and analysis of mainframe Db2 logs but also established a foundation for smarter, data-driven mainframe management. By automating routine checks, enhancing predictive capabilities, and fostering proactive responses, the tool demonstrated its potential to transform mainframe administration practices and improve overall operational efficiency
Evaluation of photocatalytic, antimicrobial and anticancer activities of ZnO/MS (M = Zn, Cd or Pb) core/shell nanoparticles
No full textZinc oxide nanoparticles were synthesized by co-precipitation method followed by covering with MS (M = Zn, Cd, or Pb) to obtain ZnO/MS core/shell nanoparticles using chemical method. The formation of core/shell nanoparticles were authenticated by various spectroscopic techniques. The photocatalytic activity of the synthesized core/shell nanoparticles shows the significant role of the shell layer in the photodegradation of methylene blue. The antimicrobial activity has been evaluated against two Gram (–ve) (E. coli and K. pneumoniae) and two Gram (+ve) (E. faecalis and S. aureus) bacterial, and two fungi (A. niger and C. albicans) strains. In vitro anti-proliferative activity of ZnO and ZnO/MS core/shell nanoparticles at a concentration of 0.06 M was evaluated against two human cancerous cell lines such as breast (MCF-7) and lung (A549), and one normal human kidney (HEK-293) cell line by MTT assay. DNA fragmentation analysis proved the inhibition of proliferation through induction of apoptosis.No Full Tex

EQUALIZING ASYMMETRY DELAY FOR ALIGNING SIGNALS ON AIR INTERFACE IN 5G/LTE-A XHAUL/FRONTHAUL C-RAN NETWORK
No full textThe stringent performance criteria that are required in a, for example, Third Generation Partnership Project (3GPP) Fifth Generation (5G) fronthaul network raise a number of challenges. To address those types of challenges, techniques are presented herein that support, among other things, removing path asymmetry at a service layer to align the signal at an air interface in 3GPP Fourth Generation (4G) or 5G converged wireless and optical transport (often referred to as \u27XHaul\u27), fronthaul, or centralized radio access network (C-RAN) use cases; thus, equalizing the delay between an uplink and a downlink direction. Aspects of the techniques presented herein encompass, among other things, a custom extension header in a Radio over Ethernet (RoE) packet to support the conveyance of timestamps, the dynamic configuration of a re-timer buffer depth, etc. Additionally, aspects of the techniques presented herein may be leveraged for other transport applications where, for example, an application over a transport network expects a symmetric delay as a wider scope
THERMAL MANAGEMENT OF BATTERY PACK IN ELECTRIC VEHICLES
No full textIn electric vehicle, battery is the main source of energy for tractive power. It is technically known as “Rechargeable Electrical Energy Storage System (REESS). The durability and efficiency of the REESS is mainly based on its charging rate, discharging rate, Depth of Discharge (DOD) and operating temperature. For a given REESS the charging rate, Discharging rate at conditional temperature and DOD are the main characteristics which are constant. The operating temperature of the REESS can be effectively controlled by optimized design of ventilation systems and enhanced energy efficient electric components. During charging and discharging, REESS temperature rises due to its internal resistance. Rapid charging and discharging of REESS leads to rise in its temperature beyond its safe operating limit. The maximum efficiency coupled with design intended life of REESS shall be attained when it is operated at the temperature of 100C to 45°C. The cell (which is the individual building block of REESS) temperature across the battery pack has to be maintained uniformly. Uneven cell temperatures cause improper charging and discharging and reduction in its capacity and life. The following issues are currently,
One particular cell temperature reaches to its cut back temperature, during high speed drive.
The overall battery pack temperature reaches its cut back temperature, after undergoing cyclic charge and discharge (drive) of the vehicle.
This project is intended to
Identify the heat source / root cause for heat source
Assess/Calculate the heat generation rate
Design the optimum size of conducting buses and ventilation system (mass flow rate of the coolant across the REESS).
Validate the design by conducting set of field test
Use of Computer Access Technology as an Alternative to Writing for a Pre-School Child with Athetoid Cerebral Palsy—A Case Report
No full textThe purpose of this study was to demonstrate the use of an outcome-driven model of decision-making in the implementation of computer access technology (CAT) for a pre-school child with athetoid cerebral palsy. The child did not have the fine motor skills required to hold a pencil but had the cognitive abilities to learn to write; therefore, we explored the use of a CAT device to enable written communication. Case study methodology was used to describe the selection process, child-level outcomes, and clinical challenges faced by the therapist in the use of a consortium model that was designed for an outcome-driven model of decision-making. The critical role of an occupational therapist in this process using a family-centered approach is discussed
