A novel now commonly used device in many countries called a "weed-wacker" is a mechanical rotating device with a cord used to trim lawns and grass. A case of a 14-year old boy with a false aneurysm of the brachial artery is presented; he sustained a missile injury by a piece of rusty steel projected by use of a weed wacker. Missile injuries by nail guns and bullets have been documented in the l...

Microplastic content was analyzed in road dust, soils alongside roads and stormwater run-offs Al Ain City, Abu Dhabi. Apart from tire wear material, fibers degradation products of meso- macroplastics such as plastic bags bottle tops were found to be the most dominant microparticles. Speed bumps artificial turf/lawns also evaluated potential sources microplastics on roads. It that arid regions A...

In West Africa and Nigeria in particular, many virgin plants are still waiting to be evaluated for their medicinal importance. Claims of plants with folk medicinal applications need to be evaluated and verified. Gomphrena celosioides (family – Amaranthaceae) is a weed grown in lawns and the biological activity of the extract had earlier been established. In the present study, the plant was coll...

Abstract Objective tests are not widely used to guide fall N fertilization of turfgrasses, and is applied at predetermined rates regardless plant‐N status. This study was conducted across 3 yr in Connecticut determine if verdure concentrations total N, dry‐tissue extractable nitrate (NO )–N, fresh sap NO –N could for a mixed‐species, cool‐season turfgrass lawn. Field experiments were set out wi...

Accurate determination of carbon balances in heterogeneous ecosystems often requires the extrapolation of point based measurements. The ground resolution (pixel size) of the extrapolation base, e.g. a land-cover map, might thus influence the calculated carbon balance, in particular if biogeochemical hot spots are small in size. In 5 this paper, we test the effects of varying ground resolution o...

Gamma phage specifically lyses vegetative cells of Bacillus anthracis and serves as part of the basis for identification of isolates from agar cultures. We report our study to standardize gamma phage production and preparation and to validate the assay for routine use. Unstable phage preparations were largely reduced through propagation of phage on blood agar cultures of the avirulent B. anthra...

Bioswales are used to attenuate stormwater pollution, but their long-term sustainability regarding sequestered metals is relatively unknown, and a clear rationale for prioritizing soil management lacking. Impervious areas draining into four 14-year-old suburban bioswales were delineated, which surface soils (top 10 cm; 72 samples) sampled; from 4 adjacent reference sites also sampled. Total wat...

Urban soils can, when not sealed, store a considerable amount of carbon (C) especially under cool climates. Soil C sequestration is controlled by plant functional type, but the mechanisms which types affect accumulation in urbanised settings poorly known. We selected 27 urban parks varying ages (young: 5–15, old: >70 years) and 10 reference forests (>80 southern Finland to study whether ability...

We measured browsing-induced responses of Acacia trees to investigate "browsing lawns" as an analogy to grazing lawns in a semiarid eutrophic African savanna. During the two-year field study, we measured plant tolerance, resistance, and phenological traits, while comparing variation in leaf nitrogen and specific leaf area (SLA) across stands of Acacia nigrescens, Miller, that had experienced ma...
