We are building a tool that uses symbolic execution to search for BIOS security vulnerabilities including dangerous memory references (call outs) by SMM interrupt handlers in UEFI-compliant implementations of BIOS. Our tool currently applies only to interrupt handlers for SMM variables. Given a snapshot of SMRAM, the base address of SMRAM, and the address of the variable interrupt handler in SM...

Quantitative PCR (qPCR) has enabled a wide range of real-time applications including comparisons in gene expression, genotyping and SNP analysis. To ensure high data quality, the liquid handling employed in low-volume reactions must be exceptionally precise and accurate. This application note highlights the capabilities of the Echo 555 liquid handler to dispense into 384-well qPCR plates with t...

A study was carried out to identify microbiological hazards and assess their exposure associated with consumption of poultry based street food served in different localities of Hyderabad. The study indicated that chicken 65, chicken fried rice, chicken noodles, chicken Manchuria and chilly chicken are the most common recipes. A process flow diagram was developed to identify critical control poi...

Norovirus (NV) has caused large outbreaks of gastroenteritis in schools. Studies of NV epidemiology in schools related to NV outbreaks have been frequently reported. However, reports of that in schools without outbreaks are not found. Presently, NV molecular epidemiology surveillance was carried out in asymptomatic food handlers working at nonoutbreak elementary schools in Incheon, Korea, in Ma...

Homemade foods have been reported as an important contributor to some foodborne outbreaks. This study determined the prevalence and number of Salmonella spp. on selected pathways fried chicken preparation cooking at household level investigated their antimicrobial resistance. serovar was confirmed by polymerase chain reaction (PCR) partial sequencing using primer 785F 907R. Samples consisted me...

Background and Objectives: Food hygiene sanitation in various food industries or processed service providers requires special attention from the government during this pandemic, where sector remains a necessity for entire community. Monitoring evaluation are urgently needed order to break chain of transmission eliminate risk contamination processing packaging. This study was conducted determine...

BACKGROUND Contamination of baby's complementary food may occur with Escherichia coli from several sources including unclean utensils. We examined the relationship between socio-economic conditions, environmental factors, characteristics of food handlers and contamination of babies food-serving utensils with E. coli. METHODS The study was conducted in 21 villages of the Community Health Centr...

The general-purpose precise interrupt mechanism, which has long been used to handle exceptional conditions that occur infrequently, is now being used increasingly often to handle conditions that are neither exceptional nor infrequent. One example is the use of interrupts to perform memory management-e.g., to handle translation lookaside buffer (TLB) misses in today’s microprocessors. Because th...

WorkTrak is a Workflow Management System that is developed as a research product in the Division of Computing Studies Arizona State University East. WorkTrak system is a distributed Java application with a Remote Method Invocation (RMI) Server that stores the state. The WorkTrak WorkList Handler project is a web application that is based on the server side programming paradigm. This application...
