Insight into the Investigation of Diamond Nanoparticles Suspended Therminol55 Nanofluids on Concentrated Photovoltaic/Thermal Solar Collector.

Nanofluids are identified as advanced working fluids in the solar energy conversion field with superior heat transfer characteristics. This research work introduces carbon-based diamond nanomaterial and Therminol55 oil-based nanofluids for implementation in a concentrated photovoltaic/thermal (CPV/T) solar collector. This study focuses on the experimental formulation, characterization of properties, and performance evaluation of the nanofluid-based CPV/T system.

Improved Thermophysical Properties and Energy Efficiency of Aqueous Ionic Liquid/MXene Nanofluid in a Hybrid PV/T Solar System.

In recent years, solar energy technologies have developed an emerging edge. The incessant research to develop a power source alternative to fossil fuel because of its scarcity and detrimental effects on the environment is the main driving force. In addition, nanofluids have gained immense interest as superior heat transfer fluid in solar technologies for the last decades.

Infant and toddler type 1 diabetes: complications after 20 years' duration.

Objective: To compare the effect of the prepubertal duration of diabetes on the occurrence of complications in two groups of patients after the same number of years of the disease.

Research Design And Methods: This multicenter study enrolled 105 patients aged 16-40.3 years; 53 were prepubertal at diagnosis (aged 0-3) and 52 were pubertal (Tanner stage) and aged 9-14.

Parnaparin versus aspirin in the treatment of retinal vein occlusion. A randomized, double blind, controlled study.

Introduction: Retinal vein occlusion (RVO) is a common cause of unilateral visual loss. Evidence based treatment recommendations for patients with RVO cannot be made because of the lack of adequate clinical trials. To compare the efficacy and safety of aspirin and of a low molecular weight heparin, parnaparin, in the treatment of RVO.

Diabetic retinopathy in childhood: long-term follow-up by fluorescein angiography beginning in the first months of disease.

Background: Little is known about minimal retinal lesions occurring in the first months of disease in children with type 1 diabetes mellitus (DM).

Objective: To detect any early retinal change and to evaluate its progression in children diagnosed with type 1 DM.

Patients: From 1979 to 1997 we examined by fluorescein angiography at diagnosis or within 15 months from the onset of DM 130 young patients with type 1 DM (mean age at diagnosis 10.
