Microeconomics of nitrogen fertilization in boreal carbon forestry [PDF]
arXiv, 2023 Nitrogen fertilization of boreal forests is investigated in terms of microeconomics, as a tool for carbon sequestration. The effects of nitrogen fertilization's timing on the return rate on capital and the expected value of the timber stock are investigated within a set of semi-fertile, spruce-dominated boreal stands, using an inventory-based growth ...

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 470-483, December 2022., 2022 In Yellowstone Lake, Wyoming, lake trout carcasses are used to suppress invasive lake trout embryos in an effort to conserve native Yellowstone cutthroat trout. Using a field experiment, we determined that carcass treatment had limited, non‐target effects on benthic invertebrates.

The Complexity Around Mosaic Embryo Decision Making– A Genetic Counselling Perspective
Fertility & Reproduction, 2022 Background: In recent years there is an evident increase in the interest of transferring mosaic embryos. Our genetic counselling team have reported mosaic results to over 250 patients since the beginning of 2020, and there is an upward trend in patient ...

Optimizing maize–bean cropping systems for sustainable intensification in southern Ethiopia
Agronomy Journal, Volume 114, Issue 6, Page 3283-3296, November/December 2022., 2022 Abstract Declining productivity and scarcity of cultivable land in smallholder systems call for exploring sustainable intensification options to increase productivity. Field experiments were conducted at five sites (Sites 1–5) of the Sidama region, southern Ethiopia, in 2018 and 2019 to determine the effects of cropping systems on maize (Zea mays L ...

Is day 7 culture necessary for in vitro fertilization of cryopreserved/warmed human oocytes?
Reproductive Biology and Endocrinology, 2020 Background Human embryos are usually cultured to blastocyst stage by Day 5 or 6 after insemination. However, some embryos grow slowly and reach blastocyst stage at Day 7.

Cover crops affect soybean yield components, but not grain quality
Agronomy Journal, Volume 114, Issue 6, Page 3193-3205, November/December 2022., 2022 Abstract Cover cropping is mainly used to prevent soil erosion, but the effects of individual cover crops on the subsequent soybean [Glycine max (L.) Merr.] are hardly known. Therefore, two annual field trials with 15 cover crop species and bare fallow as control were conducted in semi‐arid East Austria in 2016 and 2017.

arXiv, 2023 A knot K is the resultant of a knot H if there exists a minimal crossing diagram D of K such that some crossings of D can be altered to produce H. K is fertile if every prime knot H with crossing number less than c(K) is a resultant of K. K is n-fertile if every prime knot H with crossing number less than n is a resultant of K.
