Uncertainty, Sensitivity, and Efficiency Analysis of a Hybrid Piezoelectric–Electromagnetic Energy Harvester

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Digitalization and emerging technologies are increasing the demand for wireless sensing and the Internet of Things (IoT), which provide opportunities for autonomous sources of electricity in the form of energy harvesting systems. This paper focuses on the challenges in hybrid piezoelectric‐electromagnetic kinetic energy harvesting systems that

Glomerular hyperfiltration and increased proximal sodium reabsorption in subjects with type 2 diabetes or impaired fasting glucose in a population of the African region [PDF]

open access: yes, 2017
Background. Glomerular hyperfiltration (GHF) is a well-recognized early renal alteration in diabetic patients. As the prevalence of GHF is largely unknown in populations in the African region with respect to normal fasting glucose (NFG), impaired fasting

What Are the Limitations of Measuring Bladder Compliance, As the Sole Indicator of Future Risk to the Upper Urinary Tract and Renal Function? ICI‐RS 2025

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Introduction Maintenance of bladder filling and urinary storage at low intravesical pressures is fundamental to minimizing risk to the upper urinary tract. Bladder compliance describes the relationship between the bladder volume and the change in detrusor pressure during the filling phase of urodynamics.

Establishing Reciprocity as A Dimension of Nonprofit Entrepreneurial Orientation

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT This study introduces and characterizes reciprocity as a distinct sixth dimension of entrepreneurial orientation (EO) within nonprofit organizations (NPOs), specifically Brazilian Medical Associations (BMAs). Through a qualitative exploratory study using 16 BMAs as units of analysis and data from 11 in‐depth interviews with nonprofit sector ...

心前区监测血浆清除率测定肾有效血流量

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1982
自应用放射性示踪剂测定肾血流量以来,曾建立了多种测定方法,但多较繁琐,须连续抽血和收集尿液。1968年Razzak等介绍了在体外监测血浆清除率测定肾血流量的简便方法。我们参考此法,结合本室条件,测定了82例肾有效血浆流量(ERPF)和肾有效血流量(ERBF),并根据对同位素肾图的定量分析计算分侧肾血流量。结果报告如下。

HPLC estimation of iothalamate to measure glomerular filtration rate in humans [PDF]

open access: yes, 2016
Glomerular filtration rate (GFR) is usually determined by estimation of iothalamate (IOT) clearance. We have developed and validated an accurate and robust method for the analysis of IOT in human plasma and urine.

Enabling effective urban green space stewardship through planning: A qualitative comparative analysis in Southwest England

open access: yesPeople and Nature, EarlyView.
Abstract Amid increasing urbanisation and biodiversity decline, ‘effective stewardship’ of urban green space (UGS) is a complex but critical nature‐based solution for long‐term environmental, social and economic gain. Combining stewardship and sense‐of‐place frameworks with European nature‐based solutions guidance, we investigate which social and ...
