When dealing with system-reservoir interactions in an open quantum system, such as a photosynthetic light-harvesting complex, approximations are usually made to obtain the dynamics of the system. One question immediately arises: how good are these approximations, and in what ways can we evaluate them? Here, we propose to use entanglement and a measure of non-Markovianity as benchmarks for the d...

A new ab initio approach to the calculation of X-ray spectra is demonstrated. It combines a high-level quantum chemical description of the chemical interactions and local atomic multiplet effects. We show here calculated L-edge X-ray absorption (XA) and resonant inelastic X-ray scattering spectra for aqueous Ni(2+) and XA spectra for a polypyridyl iron complex. Our quantum chemical calculations...

The efficient water harvesting from air-laden moisture has been a subject of great interest to address world-wide water shortage issues. Recently, it has been shown that tailoring surface wettability can enhance the moisture harvesting performance. However, depending on the harvesting condition, a different conclusion has often been reported and it remains unclear what type of surface wettabili...

A series of papers in Philosophy, Ethics and Humanities in Medicine (PEHM) have recently disputed whether non-heart beating organ donors are alive and whether non-heart beating organ donation (NHBD) contravenes the dead donor rule. Several authors who argue that NHBD involves harvesting organs from live patients appeal to "strong irreversibility" (death beyond the reach of resuscitative efforts...

This bill is based on promotion of living-related donations, according to the ministry of health. A closely matched non-related person may only provide an organ out of compassion when a genetically-related donor is unavailable. Cadaveric donation is not among the designated priorities. The edict imposes strict penalties for brokers and those indulging in unsupervised removal, storage and grafti...

conclusions the present study suggests a beneficial effect of vitamin c adsministration on post-transplant function of the liver from bd liver donors. results no significant differences were observed in mrna expression ratio of il1b and il10 between two groups. despite an acceptable decrease in serum concentration of the inflammatory markers il1b and il10 at time point 2 minus time point 1 (t2-...

one of the important bottle-necks in production of microalgae based biodiesel is thelack of an efficient method for harvesting of microalgae from the culture medium. in thisstudy, the electroflocculation method was developed for harvesting of microalgaedunaliella cells from culture medium. the effect of several parameters such as thecurrent density, electrical conductivity of culture medium, ti...

The main concern of an olive grower is primarily to achieve more income and profits. A harvesting method having higher efficiency and better fruit and oil quality, but a higher operation cost leads to a lower benefit. A study was carried out to evaluate the techno-economic performances of Trunk Shaker (TS) and Mechanical Harvest Aid (MHA) shaker for harvesting the yellow and Manzanilla olive cu...

Humans have been harvesting wild populations for the entire extent of human history. In most early human societies, a successful hunt not only fed one’s family, but also brought respect from both family and community (Bolen and Robinson 2002). Although most North Americas and western Europeans today acquire their food that was planted, harvested, and processed by someone else, hunting and harve...
