Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Assessment of Local Scour at Bridges Abutment

Research Journal of Applied Sciences, Engineering and Technology, 2014
الأضرار الاجتماعية والاقتصادية هي أهم أضرار تعطل الجسر. ترتبط مشاكل استقرار هذه الهياكل ضد الفشل وعمق الدعامات ارتباطًا مباشرًا بكمية التنظيف المعدلة. كان الاقتصاد والموثوقية والاستقرار هي الاهتمامات الرئيسية بشأن تعزيز تصميم جسور الدعامة لمنع أو تقليل نظافة الركائز.

Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

Mechanics of local scour: supplement, methods of reducing scour

, 1966
The purpose of this report is to summarize the results of tests conducted at Colorado State University on the hydraulic feasibility of reducing scour by modifying pier shapes. The following models were investigated: 1. Sharp nosed piers. 2. Rectangular pier on flat footing supported on piles. 3.

Detecting scour and liquefaction using OBS sensors [PDF]

, 2016
This work examined the performance of Optical Back-Scatter (OBS) sensors for detecting sediment movement around a model subsea structure. Three types of tests were conducted using a circular cylinder model equipped with 16 OBS sensors.

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

Geological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Local scour at wide bridge piers

, 2014
Laboratory data for local scour depth at the size of wide piers are presented. Clear water scour tests were performed various pier widths (0.06, 0.076, 0.102, 0.14 and 0.165 m), two type of pier shapes (circular and rectangular) and two types of uniform ...

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,
