Background & Aim: Effects of ultra violet spectrum on plants due to their obligatory requirement for sunlight for survival are unavoidable. Direct effects of UV on plant growth and development are generally negative and usually they use many different defense mechanisms to acclimate and protect themselves. Material & Methods: The present research for the first time was conducted to investigate...

The nutritional requirements of mammalian embryos changes throughout pre-implantation period, coincident with changes in the secretion of the female reproductive tract. Therefore, it has been suggested that sequential culture media may support nutritional requirements for optimal growth of the mammalian embryos. In this study, we investigated the effect of two different concentrations (10 or 10...

background: toxoplasmosis is considered as one of the most common infectious diseases caused by the protozoan parasite toxoplasma gondii . tachyzoite is the main form of toxoplasma and continuously is maintained in cell culture or injected into the mice peritoneal cavity. this study was designed to evaluate the survival rate of rh strain of t. gondii tachyzoites in different cell free, nutrient...

Digital marketing is the component used for promotion of products and services through Internet online-based digital technologies like desktops, mobile phones other media platforms. The manner in which brands corporations has evolved 1990s 2000s. As platforms have been more integrated into everyday plans people are using devices instead visiting physical shops, campaigns become prevalent, with ...

five treatments including conway medium, media containing 0.1, 0.17, 0.3 and 0.5 mg l-1 ferrous (fe; in the first experiment), media with 1, 1.26, 1.59, 2 mg l-1 concentrations of phosphorous (p; in the second experiment) and a pure sample of tetraselmis suecica were cultured under laboratory conditions. growth rate of the algae was determined using the optical density method at 750 nm and numb...

Pseudomonas aeruginosa is an opportunistic pathogen of particular concern to immune-compromised people, such as cystic fibrosis patients and burn victims. These bacteria grow in built environments including hospitals and households, and in natural environments such as rivers and estuaries. However, there is conflicting evidence whether recent environments like the human lung and open ocean affe...

Abstract In vitro plant propagation systems such as temporary immersion bioreactors (TIBs) are valuable tools that enable production of disease-free plants with improved traits. However, TIB can be expensive, difficult to implement, and prone contamination due sugar rich media. Using rapidly growing chicory root cultures expedite design-build-test cycles, we report here an improved, low-cost ve...

the effect of stationary liquid media to improve shoots elongation in date palm cv. najda and an in vitro pre-acclimatization stage to increase the survival ercentage of plantlets in the greenhouse was investigated. two basal liquid media were tested: full strength and half strength murashige and skoog medium (ms). media were devoid of plant growth regulators (pgrs), containing 0.5 mg/l 6-benzy...

Introduction The tremendous growth of activity in the composites industry continues to create a need for materials that meet the tough demands for environmental compliance and high performance at an economical cost. Much of this activity has been focused on composite systems based on unsaturated polyester resins (UPRs) and vinyl esters (VEs) utilized in laminating, gel coat and free-flowing mol...
