Covid 19 pandemic force a lot of educational institution to shift their learning process from direct into indirect via eLearning. In fact, obstacle found when implementing effective eLearning system. This research use User Centered Requirement Engineering as methodology find the system requirement based on found. The main obstacles this are lack interaction between members eLearning, boredom an...

Introduction: Mental stress is one of the most important causes of the gastric ulcer. On the other hand, flavonoids such as quercetin show protective effects. The aim of this study was to investigate possible protective effect of quercetin on water restraint stress-induced ulcer in rats. Methods: Adult male Wistar rats were divided into seven groups each containing eight animals. The first g...

The principle of dimensionality reduction with PCA is the representation of the dataset ‘X’in terms of eigenvectors ei ∈ RN  of its covariance matrix. The eigenvectors oriented in the direction with the maximum variance of X in RN carry the most      relevant information of X. These eigenvectors are called principal components [8]. Ass...

Emulsion aggregate mixtures (EAMs) are blends stabilized with an asphalt emulsion for pavement base layer applications. These typically prepared using crushed aggregates and designed primarily a tensile strength-based criteria. Advances in granular material testing technologies have led to the development of advanced resilient response characterization devices such as University Illinois FastCe...

The results from the small scale application are encouraging. Our model successfully reproduces known behavior of the λ−switch on the basis of molecular level competition and resource constraints, without the need to assume protein-protein interactions between cI2 dimers and cI2 and RNA-polymerase. Even in the context of this well-known sub-system, however, few quantitative experimental results...
