BACKGROUND Incense and joss stick are generally used in the world. Most products were made in small household factories. There are many environmental and occupational hazards in these factories. OBJECTIVE To evaluate the workplace environmental and occupational hazards in small household incense and joss stick factories in Roi-Et, Thailand. METHODS Nine small household factories in rural ar...

Sites of replication in synchronized HeLa cells were visualized by light and electron microscopy; cells were permeabilized and incubated with biotin-16-dUTP, and incorporation sites were immunolabelled. Electron microscopy of thick resinless sections from which approximately 90% chromatin had been removed showed that most DNA synthesis occurs in specific dense structures (replication factories)...

BACKGROUND In Ireland, every animal is examined at slaughter for its fitness for human consumption. The aim of this study was to determine the relative effectiveness of factories in submitting and subsequently in having suspect lesions confirmed as bovine tuberculosis (TB) lesions during the years 2005-2007. This work provides an update from previously published data for years 2003-2004. During...

Arthrospira are attractive candidates to serve as cell factories for production of many valuable compounds useful for food, feed, fuel and pharmaceutical industries. In connection with the development of sustainable bioprocessing, it is a challenge to design and develop efficient Arthrospira cell factories which can certify effective conversion from the raw materials (i.e. CO2 and sun light) in...

Despite the many existing Eco-design methods and tools, their use is still limited. When they are used, these methods and tools are often not integrated in the product development process. The purpose of this research is, given a special focus on Eco-design methods and tools, to increase the knowledge concerning engineering designers’ use of methods and tools. Even though more and more approach...

The Ottawa Hospital developed an evidence-based nursing internship program to meet the challenges of new graduates. The literature suggests manychallengesthattheyface during their transition from student to new graduate, with a turnover estimated as high as 60%. The program provides support to new graduates by offering opportunities for growth and autonomy, leading to active participation as te...

Determining the replication factor y settings S aner et al. describe how neighboring DNA regions stochas-tically assemble into replica-tion factories in budding yeast. A replicon is a stretch of DNA duplicated from a single replication origin. In eukaryotes, multiple replicons assemble into sub-nuclear structures called replication factories, where the replicons are duplicated by DNA polymerase...

Cauliflower mosaic virus (CaMV) forms two types of inclusion bodies within infected plant cells: numerous virus factories, which are the sites for viral replication and virion assembly, and a single transmission body (TB), which is specialized for virus transmission by aphid vectors. The TB reacts within seconds to aphid feeding on the host plant by total disruption and redistribution of its pr...

Homologous chromosomes can pair in somatic and germ line cells, and many mechanisms have been proposed to explain how they do so. One popular class of models involves base-pairing between DNA strands catalyzed by recombination proteins, but pairing still occurs in mutants lacking the relevant functional proteins. We discuss an alternative based on two observations: transcription occurs in facto...

according to the increased fungi contaminations and related damages, microbiologist's incentive in considering the fungal contaminations in human habitats had increased. some of fungi cause disease through production of toxins in animals as well as humans. since these toxins are not easily distinguishable, then it is crucial to study their characteristics. aspergillus are among the most importa...
