Demodex spp. (Acari: Demodicidae) Infestation in Humans: Diagnostic Clues and Therapeutic Approaches to Primary and Secondary Demodicosis.
Abstract: Demodicosis represents an inflammatory dermatosis and adnexal disorder arising from pathologic overgrowth of Demodex mites, primarily Demodex folliculorum and Demodex brevis, which are ubiquitous human ectoparasites residing in pilosebaceous units and eyelid margins. Once regarded as benign commensals, these mites are now recognized as primary drivers or key cofactors in diverse clinical phenotypes, including papulopustular eruptions, pityriasis folliculorum, rosacea-like disorders, blepharitis, meibomian gland dysfunction, and exacerbations of comorbid dermatoses such …

A Comparative Study of Lipid Profile in Pre-Dialysis and Post-Dialysis End-Stage Renal Disease Patients
Abstract: Background: Chronic kidney disease (CKD) represents a major public health concern in India, with its prevalence increasing at an alarming rate. Individuals with CKD are at a substantially higher risk of developing cardiovascular disease (CVD), which remains the leading cause of mortality in this population. Dyslipidemia is particularly pronounced among patients with end-stage renal disease (ESRD); however, limited data are available regarding the impact of hemodialysis on lipid profile alterations. …

AEROGELS – A VALUE ADDITION TO HARVEST SOLAR ENERGY
Abstract: Aerogels are a class of synthetic porous ultralight material that was created in 1930 and derived from a gel, in which the liquid component has been replaced with a gas without collapsing the gel structure by freeze-drying. It is made of silica, but carbon, iron oxide, gold, copper, polymer etc. can also be used. During freeze drying the liquid in the gel is slowly dried off without collapsing the solid …

Al-MMC Foam: Synthesis and Characterisation
Abstract: Aluminium alloy composite foams are produced in the laboratory using TiH2-CaCO3 dual foaming agents. The density of the developed material varied along various cross sections. There exists a more pronounced variation in density along the direction of foaming. Compressive and tensile tests are performed on Aluminium Metal Matrix composite (Al-MMC) specimens of different relative density. The compressive stress-strain response of the material establishes their engineering utility in terms of their …

Investigation of Local Weighting Materials as a Substitute To Barite In Drilling Mud Formulation
Abstract: Weighting materials are important components needed to increase the density of drilling mud in order to provide enough hydrostatic pressure to balance abnormalpore pressures. In Nigeria, millions of dollars are spent annually in importing barite to serve this purpose. However, there exists large reserves of weighting materials such as barite, hematite, dolomite, calcite, ilmenite in Nigeria hence the need to investigate the suitability of these materials as substitute for imported …

A Study on the Sintering Behavior of Al2O3/Y2O3 Doped ZrO2 Composites
Abstract: AbstractZirconia ceramics are widely used as cutting tools due to their very high hardness, excellent fracture toughness, flexural strength, and wear-resistance properties. Tetragonal zirconia exhibits better mechanical properties due to the transformation toughening of zirconia. The superior mechanical properties in zirconia are mainly due to higher density and controlled microstructure. In the present work, an attempt has been made to prepare near full-dense zirconia bodies with controlled microstructure by optimizing …
