Metproxybicyclone, a Novel Carbocyclic Aryl-dione Acetyl-CoA Carboxylase-Inhibiting Herbicide for the Management of Sensitive and Resistant Grass Weeds.

Postemergence control of grass weeds has become problematic due to the evolution of resistance to 5-enolpyruvylshikimate-3-phosphate synthase, acetyl-CoA carboxylase (ACCase), and acetolactate synthase-inhibiting herbicides. Herein we describe the invention and synthesis journey toward metproxybicyclone, the first commercial carbocyclic aryl-dione ACCase-inhibiting herbicide for the cost-effective management of grass weeds in dicotyledonous crops and in preplant burndown applications. Glasshouse and field experiments have shown that metproxybicyclone is safe for use on soybean, cotton, and sugar beet, among other crops.

First case of evolved herbicide resistance in the holoparasite sunflower broomrape, Wallr.

The development and commercialisation of sunflower varieties tolerant to acetolactate synthase (ALS)-inhibiting herbicides some 20 years ago provided farmers with an alternative method for the cost-effective control of . In 2020, however, two independent sunflower broomrape populations from Drama (GR-DRA) and Orestiada (GR-ORE), Greece, were reported to be heavily infested with after application of the ALS-inhibiting herbicide imazamox. Here we have investigated the race of GR-DRA and GR-ORE and determined the basis of resistance to imazamox in the two Greek samples.

Study of curtaining effect reduction methods in Inconel 718 using a plasma focused ion beam.

The curtaining effect is a common challenge in focused ion beam (FIB) surface preparation. This study investigates methods to reduce this effect during plasma FIB milling of Inconel 718 (nickel-based superalloy). Platinum deposition, silicon mask and XeF gas injection were explored as potential solutions.

Perceptions de pères vivant avec un fils ou une fille adulte ayant une déficience intellectuelle sur la transition de l'après-parents.

With the increase in life expectancy, many people with intellectual disabilities (ID) are living in the family home with their parents. This research focuses on the experience of 17 fathers of adults with ID. These fathers answered a questionnaire including open and closed questions.

[Post-parenting: An exploratory study of the perceptions of aging mothers with an intellectually disabled adult].

Families of adults with an intellectual disability (ID) face post-parent transition when they can no longer assume their son's or daughter's care. This exploratory study aims to assess the perceptions of 12 mothers (Mage = 65.1; years, SD: 11) sharing a household with an adult with an ID (Mage = 36.

Aryldiones incorporating a [1,4,5]oxadiazepane ring. Part 2: chemistry and biology of the cereal herbicide pinoxaden.

Background: Pinoxaden is a new cereal herbicide that provides outstanding levels of post-emergence activity against a broad spectrum of grass weed species for worldwide selective use in both wheat and barley.

Results: Factors influencing activity and tolerance to pinoxaden were in part linked to distinct structural parts of the active ingredient. Three complementary contributions that decisively impact upon the herbicidal potency against grasses were identified: a preferred 2,6-diethyl-4-methyl aromatic substitution pattern, a dione area suitable for proherbicide formation and beneficial adjuvant effects.

Is a quantitative risk assessment of air quality in underground parking garages possible?

Unlabelled: Little information is available about the health risks associated with time spent in underground parking garages. The objective of this study was to determine whether it is possible to quantify the health risks associated with these garages without epidemiologic data on the subject. We followed the standard procedure for health risk assessment.

Prevalence of sexual abuse among patients with functional disorders of the lower gastrointestinal tract.

To evaluate the links between gastrointestinal disorders and sexual abuse, we asked 344 patients consulting in a specialized tertiary care university hospital or a gastroenterologist in private practice, if they had been sexually abused. Forty per cent of patients suffering from lower functional digestive disorder gave a history of having been victims of sexual abuse in contrast to only 10% of patients with organic diseases (P < 0.0003).

Biofeedback re-education of faecal continence in children.

The purpose of this prospective study was to see if pretreatment anorectal motility can predict successful correction of faecal incontinence with biofeedback. Forty-seven consecutive children, aged 5 to 18 years, were treated. They had been treated for idiopathic constipation with faecal impaction, but had remained incontinent (n = 15), had been operated for congenital anorectal malformations of high (n = 19) or low (n = 2) type, or had a number of organic congenital pelvic abnormalities (n = 11).

Adolescents and microcomputers: sex differences, proxemics, task and stimulus variables.

Questionnaires concerning attitudes toward use of microcomputers at home, in school, and at video arcades were administered to 879 high school students. Direct observations of adolescent proxemics and sex differences, and of various parameters of video games in 18 video arcades were made. A thorough and representative content analysis of sex bias of microcomputer software advertising brochures was carried out.

Sleep positions and postural shifts in elderly persons.

The sleep characteristics and the body positions of four men and four women ranging in age from 65 to 75 yr. were monitored in the laboratory for 2 consecutive nights preceded by 2 adaptation nights. Overall, there was an average of 16 position shifts per night with duration of position averaging 33 min.
