Multidimensional constructs are widely used to represent several distinct dimensions as a single theoretical concept. The utility of multidimensional constructs relative to their dimensions has generated considerable debate, and this debate creates a dilemma for researchers who want the breadth and comprehensiveness of multidimensional constructs and the precision and clarity of their dimension...

Chemistry is inherently a laboratory-based discipline. Even historically, where instructors often exclusively demonstrated chemical phenomena to the class, the value and need for students to carry out their own experiments was clearly recognized [1]. As such, practical laboratory work is frequently included as an established part of many modern university chemistry programs [1]. Over the years,...

In the Latin American region there is a notable absence of conceptual coherency in the use of the terms governability and governance. This is true for their application to both the social and political sciences and health. Researchers' understanding of governance varies, and the concept is used heterogeneously within academic circles, with ignorance of the term on the part of decision-makers an...

Ferrocement or Ferro-concrete is a system of reinforced mortar or plaster applied over layers of metal. It consists of closely spaced, multiple layers of mesh or fine rods completely embedded in cement mortar. It has a wide range of uses including sculpture and prefabricated building components. Ferro concrete is relatively a new material and has good strength and resistance to impact. When use...

Melanoma or Skin lesion is the most dangerous type of skin cancer. If melanoma is recognized and treated early, it is almost always curable. In this regard, several imaging techniques have been explored to improve the diagnosis accuracy of skin lesions. The first step in these systems is skin lesion segmentation. The next essential step is feature extraction and pattern analysis procedures for ...

Alcohol addiction is a complex disease with both hereditary and environmental influences. Because molecular determinants contributing to this phenotype are difficult to study in humans, numerous rodent models and conditioning paradigms have provided powerful tools to study the molecular complexities underlying these behavioral phenotypes. In particular, specifically bred rodents (i.e., selected...
