Day 1 keGFRCr and keGFRCysC performed best in the diagnosis of AKI, with an AUC of 0.85 (0.74–0.96) and 0.86 (0.76–0.97), and an ideal cutoff point of 103 and 100 mL/min, respectively [Table 2]. Day 1 E/G ratio was also diagnostic of AKI, but with a lower AUC of 0.69 (0.56–0.82). The study site was in the Hortobágy National Park in East-Hungary, near the settlement Tiszafüred. The national park is characterised by open habitats, such as alkali grasslands, marshes and loess steppes48. The region has a moderately continental climate, with a mean annual precipitation of 550 mm and mean annual temperature of 9.5 °C, but with high variability between years49.

Looking only at his seconds of productive time, his PR would have been 105%. The issue resides on the amount of non-productive time that agent Fisher had during the day. Agent Fischer has clearly performed above target, and the shift is not an issue since it’s all productive time. Even with a seconds of productive time, https://turbo-tax.org/turbotax-super-bowl-commercial-tv-ad-2021-taxfacts/ his PR would have been 75% (i.e. the shift is not an issue). The issue resides on the mix of contacts handled by Fisher or on the time spent handling one or more contacts (easily identifiable looking at Fisher HT for each contact handled on August 3 and comparing it to Target AHT for each of the contact handled).

What Is the Reserves-to-Production Ratio?

The lack of long-term reliability of the reserves-to-production ratio can be attributed to several factors.

Among them, Saudi Arabia represents the fastest depleting oil fields. Curiously, Canada, Iraq and Iran have been maintaining modest R/P ratios despite having midsize reserve. United Kingdom (not listed above) has an R/P value of 6.3 with a reserve of 2.3 billion (BP, 2018). This is the lowest among “oil rich countries.” The United States represents the lowest R/P for countries possessing a reserve 50 billion or more. At par with the United States, Russia has also maintained low R/P (of 25), signaling the fact its reserve is depleted fast.

To generate an experimental gradient in diversity and evenness we used seed sowing treatments (Table 1). We used a randomized block design with three replicates, each of which contained five 5 m × 5 m plots along the channel. Instead of directly manipulating species numbers, the treatments were designed to manipulate the ratio of grasses and forbs (Table 1). We randomly assigned one of the five treatments to plots in each block.

There is considerable evidence for the importance of functional group richness and composition18,35,36, and also functional diversity and composition37. Further investigations of the interrelations of species and functional diversity, community structure and biomass production are necessary to advance understanding of biodiversity effects and the underlying processes33. As environmental and habitat conditions likely drive functional diversity, the effects of variation in functional diversity should be studied in a given vegetation type to provide meaningful comparisons. Three main potential explanations exist for the positive relationship between biodiversity and biomass production observed in experimental studies. Firstly, the so-called sampling or selection effect suggests that a more diverse community has a higher probability of including highly productive species21. Secondly, complementarity effects occur when differences in species resource acquisition in space and time allow a more complete utilization of resources, resulting in the increased biomass production of more diverse communities22.

At the same time, concerns about the environment have led to an earnest effort to find and develop alternative fuel sources. Less appetite for some dirtier raw materials should lead their consumption rates to drop, impacting production rates and, with them, current ratios. Twelve patients (17.1%) died, eight (11.4%) needed dialysis, and 15 (21.4%) either died or needed dialysis. Plasma creatinine, CysC, and their eGFR derivatives were not predictive of death or dialysis. On the contrary, the E/G ratio was predictive, with an AUC of 0.76 (0.63–0.89) and an ideal cutoff point of 0.68. The drainage and watering channels established in the area in the 1950s and ‘60s altered the natural water regime of the region and lowered the groundwater table50.

Namely, with increasing plant production diversity first increases, then after a certain point starts to decrease, as communities with high biomass are usually dominated by highly productive competitive species13,14. The unimodal relationship with plant productivity has also been demonstrated for strategy richness and for the variance of many traits15. However, the existence of a unimodal relationship between plant biomass production and diversity is debated8,16. More recent studies have presented primary production as the dependent rather than the independent variable6,17, usually by demonstrating that biomass production generally increases with plant diversity in newly established experimental communities18,19.
