The productivity of alfalfa is associated with a large amount nitrogen (N) and phosphorus (P); the addition exogenous N P fertilizers can fully exploit growth potential alfalfa. However, there uncertainty about relationship between changes in photosynthetic physiology anatomy. We conducted field fertilization experiments on second third years under drip irrigation, as well measurement physiolog...

Short leg (SLW) and patellar tendon bearing walkers (PTBW) are orthotic appliances† which have been recently designed as alterna­ tive devices to traditional plaster cast immobili­ zation. The indications for use of lower leg walkers include severe ankle sprains, and ankle and foot fractures. Orthopedic walkers are con­ venient to use, lightweight, and removable to perform joint range of motion...

The basis used for expression of carbon dioxide exchange rate (CER) of single leaves may alter the relative ranking of genotypes being selected for a breeding program. Therefore, field and growth chamber experiments were conducted on 16 genotypes of tall fescue (Festuca arundinacea Schreb.) to determine the relative merit of expressing CER data on a leaf area or leaf weight basis. Genotypes wer...

Corononcodes ziegleri spec. nov. is described and illustrated based on material from Iran. The species represents the second Palaearctic representative of this panopine genus. In addition, C. siculus Bezzi is recorded from Fuerteventura (Canary Islands, Spain) for the first time. An identification key to the Palaearctic species of Corononcodes is presented. Additional faunistic records for the ...

BACKGROUND To address how natural disturbance, forest harvest, and deforestation from reservoir creation affect landscape-level carbon (C) budgets, a retrospective C budget for the 8500 ha Sooke Lake Watershed (SLW) from 1911 to 2012 was developed using historical spatial inventory and disturbance data. To simulate forest C dynamics, data was input into a spatially-explicit version of the Carbo...

This study was conducted to evaluate the response of Iranian promisinglate blooming almond genotypes to deficit-irrigation stress on GN15 rootstock. One-year old plants subjectedto three deficit-irrigation, including moderate and severe stress (soil water potential, Ψsoil = -0.8 and -1.6 MPa, respectively) and a control treatment (Ψsoil= -0.33 MPa), were applied for six weeks to five grafting c...

Gene array technology was applied to tomato as a model system to examine plant physiological response to silverleaf whitefly (SLW), Bemisia argentifolii (a.k.a. Bemisia tabaci biotype B) feeding. Our objective was to study gene expression in tomato plants subjected to a moderate infestation of whitefly. Plants were destructively harvested 25 days after infestation and samples of old and young l...

The formation of a biofilm is preceded by bacterial retention and proliferation on surface. Biofilm development surfaces can cause numerous issues in terms fouling transmission contamination. design fabrication that prevent may provide potential solution to reduce surfaces. An EdgeWave, Nd:YVO4 picosecond laser was used generate two periodic surface topographies 316L stainless steel with withou...
