Tomato (Lycopersicon esculentum) is an important member of the Solanaceae family. It is mainly used as food and cash crop globally. Tomato also serves as an ornamental plant in some parts of the world. In urban areas, this crop is included in the foodscaping systems where it is grown in hanging baskets, growing pots and aquaponics for aesthetic and food purposes. Tomato production is m...

Today, stem cell transplantation is a hot topic in scientific circles as a novel therapeutic approach to repair the structure and function of central nervous system. The safe and neuroprotective effects of cell therapy in models and traumatic brain injury patients were evaluated in many experimental and clinical studies in recent decade and somewhat promising results were provided to the scient...

Problem and purpose: Study opportunities or sabbaticals are still treasures for study and academic reflection. Research at Shiraz University has not concentrated on examining the flow and experiences of study opportunities related to doctoral students, one of the most influential people in producing knowledge. The purpose of this study was to analyze the lived experiences of doctoral students i...

Multi-grade classes are used for small groups of students in which one teacher for each gread is impractical. The purpose of this study is to investigate the current situation of education and learning in multigrade classrooms from the perspective of teachers in North Khorasan province. To achieve this goal, phenomenological research method was used as a qualitative method. Participants in the ...

machines and process calculi The first model to capture the complex interplay between non-determinism and concurrency in distributed systems was Petri Nets [Pet], these nets were designed information flow in natural as well as man-made systems. In the early eighties, algebraic process calculi [BHR][Mil] were designed to model interactive systems hierarchically, and to model their behaviour abst...

It is a rare twenty-first century biologist who hasn’t found themselves at some point dreaming of a simpler, less administrative, more collegial time in research. For some, that dream may entail a trip back to the 1950s, when early molecular biology hooligans shook each other down for ideas in the pubs of Cambridge. But for Howard Hughes Medical Institute, the dream lies in the near future and ...

Hemp (Cannabis sativa L.) was widely cultivated in Europe in the mid-16th Century for food (porridge), and for fiber. Hemp was brought to South America from Spain in 1545. The original use of hemp in North America is attributed to Puritans in New England who applied the fiber to the production of cloth and household fabric. However, hemp was secondary in production and use to flax for cloth. St...

INTRODUCTION The chemical industry is a much safer place to work than many industries with fewer inherent hazards. Nevertheless, almost all the accidents that have occurred need not have occurred. Most of them have happened before and have been described in published reports. Someone knew how to prevent them even if the people on the job at the time did not. There is something seriously wrong w...

I review some central physics opportunities at the 15 . . . 30 GeV continuous beam electron accelerator ELFE, proposed to be built in conjunction with the DESY linear collider. Our present detailed knowledge of single parton distributions in hadrons and nuclei needs to be supplemented by measurements of compact valence quark configurations, accessible through hard exclusive scattering, and of c...

INTRODUCTION The genus Vigna Fabaceae, formerly Leguminosae, is composed of more than 200 species that are native to the warm regions of both the old world and new world. Vigna is closely related to Phaseolus, which is composed of more than 20 species that are native to warm or tropical regions of the New World. A number of species previously placed in Phaseolus are now placed in Vigna. The gen...
