Lekan Taofeek Popoola
In the past, lives and wealth have been lost due to corrosion in almost all engineering fields. Not only this, the cost of reviving damaged equipments in the industry due to corrosion contributed a lot to the gross domestic product of a nation. Thus, all hands must be on desk to combat this harzadous act via time to time research on its final resolution. However, current research works have revealed effective and reliable corrosion inhibitors from pharmaceutical drugs, plant extracts and ionic liquids as organic green corrosion inhibitors (OGCIs) with accommodative attributes such as being environmentally friendly, readily available, biodegradable, non-harmful, relatively cheap and many others to mention a few...

Ali E Wolpern, Kyle J Sherwin, Whitney D Moss, Ingrid E Nygaard, Marlene J Egger, Timothy A Brusseau, Janet M Shaw
Background: There are few studies that objectively assess physical activity using accelerometry in postpartum women and none that do so before 3 months postpartum. It is not known whether accelerometry can be successfully used in the early postpartum period and thus benefit studies designed to assess the health benefits and risks of early physical activity. Wear compliance may be substantially lower several weeks after childbirth, given the overwhelming nature of the early postpartum period, particularly for first time mothers...

Nitya Beriwal, Tashi Namgyal, Pema Sangay, Asmaa Monther Al Quraan
The anti-oxidant effects of melatonin and the immune-pineal axis are well established. However, how they play a role in the pathogenesis of neurodegenerative diseases is not well elucidated. A better understanding of this neuro-immuno-endocrinological link can help in the development of novel therapies with higher efficacy to alleviate symptomatology, slow disease progression and improve the quality of life. Recent studies have shown that the immune-pineal axis acts as an immunological buffer, neurohormonal switch and it also intricately links the pathogenesis of neurodegenerative diseases (like Multiple sclerosis, Alzheimer's disease, Parkinson's disease) and inflammation at a molecular level...

A new tool was created to assess the factors that inhibit curiosity in working adults. The Curiosity Code Index (CCI) measures four factors that inhibit curiosity: fear, assumptions, technology, and environment. The validity of the CCI was evaluated using exploratory and confirmatory factor analyses. The factor analysis with Varimax Rotation indicated a Cronbach α of .85 for fear, .68 for assumptions, .86 for technology, and .75 for environment. Although there are other tools that measure whether individuals are curious or open to experience, there are no tools that measure these four factors that inhibit curiosity...

Christos Michael Suriano
The Inositol 1,4,5-trisphosphate receptor type 1 protein (Ip3r1) performs an essential role for the induction of cerebellar long-term depression. Here, I describe the use of RT-PCR, qPCR, western blotting and immunohistochemistry to assay Ip3r1 gene expression and localize Ip3r1 protein in the hindbrain of the elasmobranch fish, Leucoraja erinacea . Elasmobranchs are representatives of the most basal, yet extant lineage of gnathostomes, or jawed vertebrates. The cerebellum is a synapomorphy for gnathostomes and thus elasmobranch cerebellar physiology may serve as a proxy for the ancestral state of other jawed vertebrates...

Chemical characterization of the presence of oil in environmental samples are performed using methods of varying complexity. Extraction of samples with an organic solvent and analysis by fluorescence spectrometry has been shown to be a rapid and effective screening technique for petroleum in the environment. During experiments, rapid analysis of oil by fluorescence provides the opportunity for researchers to modify the experimental conditions in real time. Estimated Oil Equivalents (EOE) relies on the fluorescence measurement of the aromatic compounds to estimate the oil concentration...

This paper considers the distribution system of a school feeding program (mid-day meals), wherein a set of delivery vehicles transfer cooked food from a kitchen facility to various schools within a specified delivery deadline. The food is required to be delivered before the lunch period, which is consistent across all the schools. A delay in food delivery can deprive students of their lunch, and, therefore, designing the vehicle routes for such distribution systems and maintaining a strict delivery deadline becomes critical...
