The conversion of native ecosystems to residential dominated by lawns has been a prevailing land-use change in the United States over past 70 years. Similar development patterns and management cause many characteristics be more similar each other across broad continental gradients than that former ecosystems. For instance, lawn irrigation fertilizer applications potential influence soil carbon ...
Research on plastics in global ecosystems is rapidly evolving. Oceans have been the primary focus of studies to date, whereas rivers are generally considered little more than conduits marine ecosystems. Within a watershed, however, all sizes retained, transformed, and even extracted via freshwater use or litter cleanup. As such, plastic terrestrial an important but underappreciated component po...
OBJECTIVE Compare the pressures measured by improvised irrigation techniques to a commercial device and to prior reports. METHODS Devices tested included a commercial 500-mL compressible plastic bottle with splash guard, a 10-mL syringe, a 10-mL syringe with a 14-ga angiocatheter (with needle removed), a 50-mL Sawyer syringe, a plastic bag punctured with a 14-ga needle, a plastic bottle with ...
the trial randomized complete block design with four replications in summer 1394 in a farm located in the share ray to study the effects of different methods of weed control on the yield and quality of forage maize varieties (sc.704) was performed. the experiment consisted of black plastic mulch, black plastic mulch silver, vetch cover crop with a density of 100 per cent, with 50 per cent vetch...
This study reports the use of an overturned plastic gallipot from a sterile wound dressing pack as a splashguard during the irrigation of traumatic wounds with a device consisting of a 20 ml syringe and a 21F gauge hypodermic needle. This simple, effective and cheap device can be constructed from items readily available within the emergency department or operating theatre and minimises exposure...
Aflatoxins are secondary metabolites produced by Aspergillus flavus, A. parasiticus, A. tamari, A. bombycis and A. nomius species. Relative humidity (RH) is one of the most important parameters influencing the development of aflatoxins in pistachio orchards by Aspergillus species. The type of irrigation system affects density and frequency of the Aspergillus species in the soil. In the current ...
A coupled phase field and crystal plasticity model is established to analyze formation of dislocation structures residual stresses during rapid solidification additively manufactured 316L stainless steel. The work focuses on investigating the role microsegregation related intra-grain cellular microstructure 316L. Effect shrinkage considered along with mediated plastic flow material solidificati...
Agricultural irrigation in the middle reaches of the Heihe River Basin consumes approximately 80% of the total river water. Whether the irrigation depth matches the water uptake depth of crops is one of the most important factors affecting the efficiency of irrigation water use. Our results indicated that the influence of plastic film on soil water δ(18)O was restricted to 0-30 cm soil depth. B...
Modern sulamalarda sulama suyunun miktarı, zamanı ve yöntemi kadar kalitesi de önemlidir. Yeterli iyi kalitede su bulunamayınca açısından uygun olmayan sular kullanılmaktadır. Bu da toprakta tuzluluk problemini artırmaktadır. nedenle, Hakkari ilinde amacıyla kullanılan havuzlardaki kalitelerinin değerlendirilmesi amaçlanmıştır. amaçla, 10 tane havuzundan, Haziran, Temmuz, Ağustos Eylül aylarınd...
Intensive forestry has resulted in considerable increases in aboveground stand productivity including foliar and belowground biomass which are the primary sources of soil organic matter. Soil organic matter is important for the maintenance of soil physical, chemical and biological quality. Additionally, sequestering carbon (C) in soils may provide a means of mitigating increasing atmospheric ca...
