Na primeira parte, este artigo procura identificar as principais soluções propostas pelas teorias da justiça contemporâneas para a distribuição de bens escassos. Na segunda parte do trabalho, busca-se aplicá-las a modelos ideais de sistemas de saúde pública.

Abstract:

Visões distorcidas da natureza da ciência, que retratam os cientistas como gênios peculiares, neutros e isolados, justificam, em grande medida, tanto o insucesso de uma educação científica adequada, como a resistência à ciência por parte de muitos estudantes. Charles Robert Darwin (1809-1882) é um exemplo dessa representação e o presente artigo busca desconstruí-lo. Com o objetivo de oferecer elementos que tornem os processos de ensino e aprendizagem mais alinhados com uma abordagem realista da natureza da ciência, utilizou-se a sociologia da ciência latouriana para empreender uma análise acer

Abstract:

Properties of soil proteases and proteases from Bacillus spp. obtained from water-logged paddy fields treated with organic manure or chemical fertilizer or not treated with fertilizer were compared to elucidate the sources of soil proteases. The major extractable soil proteases were metal chelator sensitive neutral proteases that were active in hydrolyzing benzyloxycarbonyl-L-phenylalanyl-L-leucine and benzyloxycarbonyl-L-phenylalanyl-L-tyrosyl-L-leucine. In this respect they resembled extracellular proteases from Bacillus subtilis (six isolates), Bacillus cereus (four isolates), and Bacillus

The population genetic structure of Phytophthora infestans in Ecuador was assessed from 101 isolates collected from 1990 to 1992 and 111 isolates collected in 1993. All isolates were analyzed for mating type and allozyme genotype. Both samples were dominated (>95%) by a clonal lineage (EC-1) defined from neutral markers: 90/100 genotype for glucose-6-phosphate isomerase, 96/100 genotype for peptidase, A1 mating type, and a previously unreported nuclear DNA fingerprint. The remaining isolates belonged to the US-1 clonal lineage, which has a worldwide distribution. Isolates in the 1993 sample

Among other factors, the responsiveness of plants to AMF depends on the plant-fungus combination. To find out whether the AMF species or isolate is a decisive factor for growth responses of weeds, 44 AMF isolates were tested in a pot experiment for their effects on three agricultural weeds: E

ABSTRACT Paramyxoviruses enter cells by fusing their envelopes with the plasma membrane, a process that occurs at neutral pH. Recently, it has been found that there is an exception to this dogma in that a porcine isolate of the paramyxovirus parainfluenza virus 5 (PIV5), known as SER, requires a low-pH step for fusion (S.

Abstract:

Twenty-six bacterial isolates of Proteobacteria were isolated from patients with urinary tract infections from several hospitals in Babylon province. Urine samples were collected from patients with urinary tract infections, then these samples were grown on different culture media and identified by several biochemical tests. Also, their drug sensitivity was studied using nine types of antibiotics. The drug sensitivity of these samples was studied at acidic, neutral and basic pH using disk diffusion method. The study showed that ciprofloxacin and azithromycin had high activity against bacteria a

Abstract:

Rice is the most widely consumed staple food in the world, feeding over half of global population. Thailand has long been an important rice producer and exporter, ranked 6th in the world regarding total milled rice yield. Unfortunately, the major problem of rice production worldwide is rice blast disease which caused by the fungus Magnaporthe oryzae. The most effective method for managing rice blast disease is using resistant rice varieties. One of Thai rice variety that show highly resistance against various rice blast fungus isolates is Jao Hom Nin (JHN) rice, containing broad-spectrum resis

A unique biotype of the Fusarium wilt pathogen, Fusarium oxysporum Schlecht. f.sp. vasinfectum (Atk) Sny. & Hans., found in Australia in 1993 is favored by neutral or alkaline heavy soils and does not require plant parasitic nematodes to cause disease. This makes it a threat to 4–6 million acres of USA Upland cotton ( Gossypium hirsutum L.) that is grown on heavy alkaline soil and currently is not affected by Fusarium wilt. In 2001–2002, several shiploads of live cottonseed were imported into California for dairy cattle feed. Thirteen F. oxysporum f.sp. vasinfectum isolates and four isolat

The MICs measured in air alone were lower for most isolates than those measured in 5% carbon dioxide, illustrating the “pH effect” of incubation in carbon dioxide. Testing of isolates in 5% carbon dioxide on pH-adjusted medium (pH 8.4) resulted in MICs of one or two doubling dilutions lower

GLRaV-3 isolates were subdivided into four distinct phylogenetic clades. No evidence of positive selection was observed in the data set, although neutral selection (ratio of nonsynonymous to synonymous substitution rates = 1.1)
