Salmonella isolates that lack or overproduce DNA adenine methylase (Dam) elicited a cross-protective immune response to different Salmonella serovars. The protection afforded by the Salmonella enterica serovar Typhimurium Dam vaccine was greater than that elicited in mice that survived a virulent infection. S. enterica serovar Typhimurium Dam mutant strains exhibited enhanced sensitivity to med...

Eight preparations of soluble amyloid and degraded amyloid (DAM) were compared immunologically. Unlike amyloid fibrils, six of eight preparations of DAM proved to be relatively strong immunogens. Antisera to DAM reacted weakly or not at all with normal human serum or extracts of normal tissues, but were specifically reactive with amyloid fibrils or DAM. Comparative studies of DAM'S from eight d...

In this study, after simulating 5 years of saltwater intrusion with SEAWAT package in Astaneh–Kouchesfahan coastal aquifer, Iran, 19 strategies, including managerial, structural, and combined were investigated to reduce the intrusion. Since managerial solutions cause users’ dissatisfaction structural increase costs, two-player game theory was used identify most appropriate solution. According r...

Dissatisfaction with work boot design is common in the mining industry. Many underground coal miners believe their work boots contribute to the high incidence of lower limb injuries they experience. Despite this, the most recent research to examine underground coal mining work boot satisfaction was conducted over a decade ago. This present study aimed to address this gap in the literature by as...

With the fast development and utilization of underground space resource in cities, the spatial distribution of urban underground pipelines becomes more and more complex. How to efficiently utilize the latest technology, realize underground space resources' management, visualization, layout optimization and mine applications, are challenging issues in current digital city development. Taking int...

Urinary tract infections (UTI) are among the most frequently encountered infections in clinical practice globally. Predominantly a burden among female adults and infants, UTIs primarily caused by uropathogenic Escherichia coli (UPEC) results in high morbidity and fiscal health strains. During pathogenesis, colonization of the urinary tract via fimbrial adhesion to mucosal cells is the most crit...

It has been shown that certain symptoms in chicks, namely, exudative diathesis, yellow coloration of the adipose tissue, and encephalomalacia, and in rats, namely, yellowbrown coloration of the adipose tissue, and depigmentation of the incisors, depend upon the consumption of vitamin E-deficient diets rich in highly unsaturated fatty acids (Dam, 1944a, b ; Dam & Granados, 1945a, b ; Granados & ...

The molecular basis for the inviability of dam-3 recA200(Ts) and dam-3 recB270(Ts) cells was studied. The dam-3 recA200(Ts) cells were inviable in yeast extract-nutrient broth or in minimal medium at 42 degrees C. Although the dam-3 recB270(Ts) cells were inviable in yeast extract-nutrient broth at 42 degrees C, they were viable at 42 degrees C in minimal medium, in which the high salt content ...

Clinical isolates of Haemophilus influenzae resistant to a broad range of 2-deoxystreptamine aminoglycosides (2-DAM) were studied. The gene responsible for resistance could be mobilized by transformation into a 2-DAM susceptible laboratory strain of H. influenzae, enabling isogenic comparisons. The transformants had the same resistance phenotype as the parental strains. There was close linkage ...

There are various evaluation methods available for the discharge rate passing from the body of dam 1) Analytical methods, 2) Numerical methods and 3) Experimental methods. In the initial stages of dam design, it is necessary to approximately calculate the seepage and board of the project. In this research, almost 600 geometric models have been considered for embankment dam with clay core which ...
