The objective of this research was to compare the composition of bacterial microbiota associated with the ruminal content (RC), ruminal epithelium (RE) and faeces of Holstein dairy cows. The RC, RE and faecal samples were collected from six Holstein dairy cows when the animals were slaughtered. Community compositions of bacterial 16S rRNA genes from RC, RE and faeces were determined using a MiS...

In the current study, experiments were carried out to investigate structural performance of reinforced concrete (RC) beams with a self-healing cover zone. The zone consists 1.5-cm-thick layer bacteria-embedded strain hardening cementitious composite (SHCC) for combination crack width control and healing. aim is bring together two emerging technologies (i.e., strain-hardening) that show great po...

In order to calculate the equivalent torsional-warping stiffness of Reinforced Concrete (RC) cores that have thin-walled open cross-section, a new analytical methodology, which combines Vlasov torsion theory with Bernoulli bending theory, is presented herein. As basis calculations, we use principal elastic reference system core from this consider known. Furthermore, start point core's exact sec...

The family of regular closed subsets of a topological space is used to introduce two concepts concerning a function f from a space X to a space Y . The first of them is the notion of f being rc-continuous. One of the established results states that a space Y is extremally disconnected if and only if each continuous function from a space X to Y is rc-continuous. The second concept studied is the...

Shoulder complaints are common in the elderly and hamper daily functioning. These complaints are often caused by tears in the muscle-tendon units of the rotator cuff (RC). The four RC muscles stabilize the shoulder joint. While some RC muscles are frequently torn in shoulder complaints others remain intact. The pathological changes in RC muscles are poorly understood. We investigated changes in...

OBJECTIVES The objective of this study is to reach a model defining factors precipitating short survival in patients with oesophageal varices and improving the understanding of such factors. Models would help to prioritize the clinical goals and intervention for saving the lives of patients. METHODS Retrospective analysis of all patients admitted to King Abdul Aziz University Hospital who had...

In Chile, office buildings are typically reinforced concrete (RC) structures whose lateral load-resisting system comprises core structural walls and perimeter moment frames (i.e., dual wall-frame system). the last 20 years, nearly 800 new have been built in country roughly 70% of them less than ten stories. Although seismic performance these was deemed satisfactory previous earthquakes, their a...
