Mentorship is critical to the development and professional growth of graduate medical education (GME) trainees. It is a bidirectional relationship between a mentor and a mentee. Mentorship has consistently been shown to be beneficial for both the mentor and mentee, with the mentee gaining valuable skills in education, personal growth, and profession…
Venous and arterial thrombosis are complex disorders involving several genetic inherited thrombotic and environmental risk factors as well as many mechanistic pathways including those of hemostatic, inflammatory and oxidative homeostasis. To provide an overview of genetic polymorphisms associated with thrombotic disorders, we studied related pathway…
Africa contains some of the richest biodiversity in the world, blessed with bountiful plants of economic importance and plants of medicinal importance which when developed would reduce our expenditure on imported drugs to meet our health needs. Plants are source of phytochemicals that possess emollients, humectants and medicinal properties. A comple…
Oil undergoes temporary viscosity changes under operating conditions in engines. Therefore, engine oils usually contain polymeric additives called viscosity modifiers. These additives are oil soluble polymers; enable the oil to provide adequate hydrodynamic lubrication at high temperatures and good starting/pumping performance at low temperatures. P…
In this chapter, we present our study of geopolymers and hybrid geopolymers synthesized with treated fly ash from eggshells (FAES) and sand from the dunes of southern Algeria using activators such as NaOH and Na2SiO3, respectively, in addition to the organic polymer polyethylene terephthalate (PET). Several parameters have been modified, such as alk…
We reported here the synthesis of new α,α-diaminoester and α,α-diamino acid derivatives, as 2-benzamido-2-[(tetrahydro-furan-2-ylmethyl)amino] acetic acid through alkaline hydrolysis reaction of corresponding N-benzoylated methyl α,α-diamino ester. The α,α-diaminoester derivative was synthesized by nucleophilic substitution of methyl α-azid…
This chapter explores the different ways in which solar radiation (SR) can be quantified for use in photovoltaic applications. Some solar radiation models that incorporate different combinations of parameters are presented. The parameters mostly used include the clearness index (Kt), the sunshine fraction (SF), cloud cover (CC) and air mass (m). Som…
Guillain Barré Syndrome (GBS) is an acute demyelinating polyradiculoneuropathy, with unusual heterogeneous clinical variants in pediatrics. There may be infection prior to the clinical manifestations of GBS. Establishing a diagnosis and treatment is challenging. In the present work, a 7 year old schoolgirl is presented, healthy, without risk fact…
The need for humidity sensors in various fields have led to the development and fabrication of sensors for use in industries such as the medical, textile, and laboratories. This chapter reviewed humidity sensors, major types and applications with emphasis on the optical fiber, nanobricks, capacitive, resistive, piezoresistive and magnetoelastic humi…
