Does temperature affect real economic activity? Using the annual Current Population Survey between 1963 and 2015, we show that there is no association between temperature and earnings, hours, or output after controlling for time-invariant spatial heterogeneity and timevarying demographic factors. These results are robust to five separate sources of micro-data, different sampling horizons, funct...

This study aimed to evaluate the most predominant strain of avian pathogenic Escherichia coli (APEC) that causes colibacillosis with respiratory manifestation in broiler chickens. Isolation and serotyping identification for isolates E. were performed. Prevalence APEC differentiated by detection 8 virulence-associated genes “astA, iss, irp2, papC iucD, tsh, vat, cva/cvi” using multiplex PCR tech...

The relationship between back pain and scoliosis is not clear. Old long-term follow-up studies reported no greater incidence or degree of back pain in adult scoliosis than in normal population when matched for age and sex. At the end of the seventies studies were contradictories. While Fowles et al (1978) concluded that untreated scoliosis could be considered as a disabling disease in the adult...

The Northeast Network in Biotechnology (RENORBIO) was established in 2004 by the Federal Government that identified the demand for this type of professional and signalizes a great opportunities them to act on the growing industry of biotechnology in Brazil. It is a network of research, development and innovation, which base is the Post-Graduation Program (PGP-RENORBIO) that have 36 institutions...

Shiga toxin-producing Escherichia coli (STEC) is responsible for several food-borne outbreaks worldwide. In this study, tissue samples of finfish (tilapia, n = 100) and (mullet, 100), twenty human hand swabs from fish sellers fishermen were tested bacteriologically STEC presence. Isolates their antibiotic susceptibility examined the presence eaeA,stx1, stx2 genes. E. identified tissues (36.5% 1...

In modern medical processes, new antimicrobial drugs are being widely used in order to rapid and essential eradication of resistant bacterial strains. Broad-spectrum beta-lactamases are enzymes originated from mutations in the common plasmid genes mediators for beta-lactamases such as TEM-1, TEM-2, and SHV-1 are transferred among bacterial species. The genes coding the production of ESBL are of...

the effect of economic growth and free trade on environment and transnational pollutions is one of the most important current discussions in the field of environmental economics. nowadays, the economics, social and developmental consequences of the climatic changes around the world is increasingly accepted and approved. in fact, the environment is considered as one of the key elements for susta...

Forty eight samples (30 wastewater and 18 river water) were collected between July and November, 2010, from different sources in Cape Town, South Africa in order to characterize verotoxic non O157: H7 Escherichia coli strains. Samples (1 ml) were inoculated into MacConkey broth (MB, 9 ml) and incubated at 37°C for 24 h, after which a loopful of the MB was then spread onto Eosin Methylene Blue (...

A survey of the microbial quality based on enterobacteriaceae counts of the table eggs sold in Egyptian markets was conducted to evaluate their quality and the possibility of presence of Enterovirulent Escherichia coli strains. Six hundred random table egg samples were collected from different shops, supermarkets and homes. Each six pooled eggs constituted a composite sample. Higher enterobacte...
