Forest managers have traditionally planned harvests using their expert knowledge. This applies mainly to the spatial distribution of harvest units. The amount of timber to be harvested is regulated by market demand. In addition to forest managers’ expert knowledge, there is a set of rules, which can be automatized. Computerized harvest planning will lead not only to saving time of forest manage...

In light of the continuous increase in organic agriculture, availability seeds has gained a lot importance. Especially since new EU regulation came into force on 1 January 2022, proposing reducing possibility using untreated conventional absence future. At same time, breeding tolerant, resistant and adapted varieties is at basis production as research to improve seed quality. this study, we inv...

Free fibula transfer can be associated with a slow and tedious dissection/harvest due to difficulty in visualizing the deeper structures. The purpose of this article is to review the first author's (Y.D.) experience with a novel technique for expedited harvest of fibula free flaps for mandibular reconstruction. A retrospective chart review was performed using the first author's clinical practic...

BACKGROUND Reconstruction of hypopharyngeal and cervical esophageal defects remains one of the greatest challenges to head and neck and reconstructive surgeons. Although the jejunal free flap is a well-known reconstructive choice, many authors prefer alternative methods because of the complication rates and donor site morbidity associated with traditional jejunal flap harvest. Laparoscopic rese...

Stock-recruitment models have been used for decades in fisheries management as a means of formalizing the expected number of offspring that recruit to a fishery based on the number of parents. In particular, Ricker's stock recruitment model is widely used due to its flexibility and ease with which the parameters can be estimated. After model fitting, the spawning stock size that produces the ma...

this study was done to evaluate the effects of harvest time on some factor of ‘ahmadaqaie’ pistachio nuts in rafsanjan. in three consecutive years (2009-2012) during three stages of friut ripening (40, 70 and 100 percent of hulling), fruit was harvested and physiological and biochemical parameters were measured. the experiments were conducted as randomized complete block design with compound an...

Trials were conducted to determine effects of AQUI-STM sedation during harvest (rested-harvest) on physiological responses and fillet quality of channel catfish, Ictalurus punctatus. Rested-harvest is defined as application of an anesthetic immediately before harvest to reduce fish activity associated with a normal harvest. Doses of 25–35 ppm AQUI-STM were effective for rested-harvest of catfis...

This dataset provides a shapefile containing approximately 3500 polygons with the location, extent, size, and year of clearcut harvest events occurring between 1984 and 2015 in forested areas of the northern Colorado, Landsat WRS-2 scene Path 034, Row 032. Harvest events were modeled and mapped using a 32 year time series of Landsat imagery, the LandTrendr algorithm, and ancillary datasets. The...

We address the impacts of regulations designed to reduce pesticide poisoning of farmers and farm laborers. Attention is concentrated on pre-harvest interval regulations that impose a time interval between pesticide application and harvest. The incidence of poisoning is determined by aggregate pesticide use, worker exposure, and toxicity. A dynamic, stochastic model of insect population growth i...
