the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The Gathering Storm: Is Untreatable Typhoid Fever on the Way?
Klemm et al. (mBio 9:e00105-18, 2018, https://doi.org/10.1128/mBio.00105-18) present comprehensive antibiotic sensitivity patterns and genomic sequence data on Salmonella enterica serovar Typhi blood culture isolates from typhoid fever cases during an epidemic in Pakistan. Microbiologic and genomic data pinpoint the identities and locations of the antimicrobial resistance genes and the outbreak...
متن کاملIs data gathering the only acceptable approach to biological science?
parasites of lizards has recently become the subject of sectional interests. In the absence of any objective criteria for classifying the group, two nomenclatures have come into current usage. Workers with interests in the natural history of the lizard parasites have emphasized the features that distinguish lizard and mammalian parasites and have tended to give the lizard parasites generic rank...
متن کاملIs pollen limited? The answer is blowin’ in the wind
Pollen from wind-pollinated trees has traditionally been assumed to be abundant and to travel long distances, resulting in extensive gene flow. However, recent empirical work by Knapp et al., genetic analysis by Sork et al., and theoretical models by Satake and Iwasa conclude that short-distance dispersal of limited pollen might be common and play an important role in causing the highly variabl...
متن کاملIncreased Strength in Wind Turbine Blades through Innovative Structural Design
When a system design approach is applied to wind turbine blades, manufacturing and structural requirements are included along with aerodynamic considerations in the design optimization. The resulting system-driven design includes several innovative structural features such as flat-back airfoils, a constant thickness carbon spar-cap, and a thin, large diameter root. Subscale blades were manufact...
