The Effects of Hydro Confining Pressure on the Flow Properties of Sandstone and Carbonate Rocks
Abstract: There is a significant effect of the hydro confining pressure of the core holder on the flowing properties of the formation rocks. This effect is caused due to the mechanical elastic deformation of the core when carrying out laboratory studies of the water shutoff and polymer compositions. Consequently, this deformation will cause changing in the permeability and voids storage capacity of the studied core samples. Therefore, under the laboratory conditions …

The Patterns of Enamel Rod after Exposure to Probiotic Beverages
Abstract: Probiotic beverages have a taste of acid that is produced by fermentation of probiotic bacteria. The acid condition can affect the structure of tooth enamel. The structure of tooth enamel is formatted by enamel prism that is composed by hydroxyapatite (HA) crystals. According to several studies, HA has a critical pH <5.5 and can be changed in 180 min by acid. The objective of the study is to describe enamel …

Measles Eradication by Vaccination: Opportunities and Challenges
Abstract: Measles is one of the vaccine preventable viral diseases that mainly occur in children. The disease was targeted for elimination by a vaccination program that was initiated three decades back. The measles death rate decreased by 74% from the year 2000 to 2010. This was short of targeted 90% mainly because of low vaccine coverage in some countries. Although, there is marked reduction in measles morbidity and mortality, still it …

Parameters of “Safety” in the Food Additive Industry: A Review of Risks and Benefits
Abstract: “Safety is in the eye of the beholder.” What is deemed “safe” by one observer may seem dangerous or risky to others. To approach this apparent quandary and assure ongoing scientific input, most food additives should be tested on laboratory animals and subsequently monitored if approved for human or animal consumption (i.e., parallel to the pathway for the approval of drugs). The term “safety” in the study of the toxicology …
