Abstract Side effects of “solar-radiation management” (SRM) might be perceived as an important metric when society decides on implementing SRM a climate policy option to alleviate anthropogenic global warming. We generalize cost-risk analysis that originally trades off expected welfare loss from costs and risks transgressing targets also include applying SRM. In first step acknowledging risks, ...

A review of modern evidence using Internet resources has identified the Stress Repair Mechanism (SRM) postulated by Hans Selye in 1951. SRM activity regulates thrombin generation to govern tissue maintenance, tissue repair, hemodynamic physiology, inflammation, and apoptosis. Thrombin utilizes ATP to energize coagulation, capillary hemostasis, chemotaxis, immune activity, mitosis, metabolism, a...

Selected reaction monitoring (SRM) is a targeted mass spectrometry technique that provides sensitive and accurate protein detection and quantification in complex biological mixtures. Statistical and computational tools are essential for the design and analysis of SRM experiments, particularly in studies with large sample throughput. Currently, most such tools focus on the selection of optimized...

A large number of power meters have been produced on the market for nearly 20 y according to user requirements. PURPOSE To determine the validity, sensitivity, reproducibility, and robustness of the PowerTap (PWT), Stages (STG), and Garmin Vector (VCT) power meters in comparison with the SRM device. METHODS A national-level male competitive cyclist completed 3 laboratory cycling tests: a su...

The aim of this study was to describe the characteristics of positron emission tomography (PET) molecular imaging combined with low-dose computed tomography (CT) in small renal mass (SRM) treated with cryoablation (CA). Currently, treatment success is defined by the absence of contrast enhancement at CT. However, the use of contrast is relatively contraindicated in patients with renal function ...

This Standard Reference Material (SRM) is a primary transfer standard certified using a national reference spectrophotometer at NIST [1-3]. SRM 2930 is complementary to SRM 930e and SRM 1930, providing levels of transmittance/absorbance that extend the range covered by those SRMs. It is intended for use in the verification of the transmittance and absorbance scales of spectrophotometers in the ...

The simple structure, low manufacturing cost, rugged behavior, high torque per unit volume and wide torquespeed range make switched reluctance motor (SRM) very attractive for industrial applications. However, these advantages are overshadowed by its inherent high torque ripple, acoustic noise, and difficulty to control. The controlled parameters in SRM drives can be selected as the turn-on angl...

The problem of torque tracking PI-controller design for switched reluctance motor (SRM) drive is discussed, where SRM magnetization characteristics are highly nonlinear, and torque is a complex and coupled function of phase current and rotor position. A distinctive feature of the control system designed is that two-time-scale motions are artificially forced in the closed-loop system by the sele...

The flux and torque of switched reluctance motor (SRM) have a highly nonlinear functional relationship with rotor position and phase current, as a consequence of the double-salient structure of the stator and rotor pole and highly magnetic saturation, which is difficult to build an accurate analytic model. In order to achieve the SRM high-performance control, it is necessary to build an accurat...

Prolonged anoxia has deleterious effects on islets. Gas-permeable cell culture devices can be used to minimize anoxia during islet culture and especially during shipment when elimination of gas-liquid interfaces is required to prevent the formation of damaging gas bubbles. Gas-permeable bags may have several drawbacks, such as propensity for puncture and contamination, difficult islet retrieval...
