there are a number of techniques available to estimate saturated-liquid molar or specific volumes or densities of liquids. in this study, a new empirical correlation is presented to calculate volume of saturated liquids as a function of critical volume, reduced temperature and acentric factor. an optimization algorithm is utilized to obtain unknown parameters of this correlation by fitting them...

metabolic alkalosis is characterized by high hco3- as it is seen in chronic respiratory acidosis, but ph differentiates the two disorders. there is no characteristic symptom or sign. orthostatic hypotension may be encountered. weakness and hyporeflexia occur if serum k+ is markerdly low. tetany and neuromuscular irritability occur rarely. we report the results of retrospective data analysis of ...

Our Journal's tendency towards the real world in applied linguistics and literary studies should have significant epistemological and methodological consequences in researching the fields. The interest in the real world makes the problems we may have in our everyday lives our 'points of departure' in research. According to my experience of research in our universities throughout their history, ...

The editor’s notes in our Journal have been so far a site for the clarification of the Journal’s policy and the task still continues. With an inclination towards solving our real world problems in language teaching (and literary studies, which I will discuss in the next issue of the Journal), we would like to take that the introduction of the concept of “life-world” to Social Sciences can be a ...

JALDA, therefore, would like to show inclination towards the view that the reality of the world is not a fixed entity standing out there to be measured by our pre-fabricated ‘scientific’ instruments. In line with Haghshenas’ argumentation, not only can theories and instruments shrink to ornamental entities but also they can turn into what Karl Popper calls pseudo-science, knowledge of an ‘ideol...
