The influence of technology in our lives emerges the need and the willingness to use it in education too. The possibility of using the Internet as an educational source is undoubtedly an interesting question. Our Web presentation focuses on the educational parameters, which could be used in the Internet, by following the journey of light, as a natural substance, through time.

A switch in cellular identity in budding yeast requires the ubiquitin-dependent elimination of pre-existing master regulators encoded by the MAT locus. Failure to disassemble the prior state not only impairs the cell type transition but imparts a hybrid cellular fate. This theme will undoubtedly arise in many developmental and disease contexts.

The authors address the value of endoscopic retrograde cholangiopancreatography, ultrasonography, computed tomography, magnetic resonance imaging and endoscopic ultrasound for the diagnosis of cystic and solid neoplasms of the pancreas, demonstrating that each of them is of great importance to undoubtedly increase the diagnostic accuracy of the biliopancreatic system diseases. The best method f...

A tremendous diversity of ligand binding proteins exists in nature. This undoubtedly creates considerable opportunities for scientific and medicinal applications. In this chapter, we will consider a range of ligand binding proteins, with particular attention to two classes, namely the ligand-binding proteins of the bacterial periplasm and odorant-binding proteins, because these proteins are the...

The advances of mobile devices and technology have permitted their inclusion on our daily activities, supporting and propelling productivity and communication on several levels. Moreover, the ever-growing diversity and potential of these devices extends their usage through multiple settings, accentuating their ubiquitous and pervasive nature. One of the major contributions to this is undoubtedl...

The notion of context in context-aware applications is not merely an issue of external situational circumstances or device/channel properties, but it could also refer to a wide array of user characteristics that have an effect throughout users’ interactions with a system. Human factors such as cognitive traits and current state, from a psychological point of view, are undoubtedly significant

botany as anatomy, biochemistry, ecology, genetics, morphology, physiology, and systematics. In the future, plant conservation, with its emphasis on the preservation of rare and endangered species, will undoubtedly also have a significant impact. The most spectacular recent innovations in biotechnology involve improved technology for genetically modifying plants and producing individuals with n...

The satellite has yielded new information on the arrangement of irregularities in sheets and the structure of plasma resonances in the ionosphere. Studies of the geographical distributions of the different kinds of spread F, sporadic E, and other phenomena will be facilitated by the satellite. More phenomena will undoubtedly be recognized as the records are studied.

Investigations on the associative interrelationships between microorganisms have engaged increasing attention in recent years. As is well known, these relationships play an important role in nature and also in many branches of industrial.microbiology. In view of the great significance of these associative phenomena in biology, and especially in microbiological ecology, this is undoubtedly a fie...

an inhibitory action in a hemolytic system. At the time of the above discussion, I.did not know whether such a solution could be prepared. Cases of hemoglobinuria following administration of quinine in malarial individuals do undoubtedly occur. In some cases, the appearance of the hemoglobinuria may be accidental. Leaving these accidental cases and without entering into the discussion of the me...
