in order to investigate the effect of mn and salinity on some physiological and echophysiological characteristics of pistachio seedlings (cv. badami-e-zarand) in sand culture (perlite medium), a factorial greenhouse experiment was carried out in the framework of a completely randomized design comprised of two factors namely: salinity (zero, 75, 150, 225 and 300 mm nacl) and mn (zero, 12, 24 and...

This paper presents experimental investigation on thermal properties (thermal diffusivity and conductivity) of AM series cast magnesium alloys. The effects the changing in Al content (from 2 to 9 constantly 0.5 Mn, wt. %) alloys properties, density hardness were comparatively analyzed. It was observed that intermetallic phases (Mg17Al12 ve Al8Mn5) found microstructure have an effect diffusivity...

Serials of Mn doping by substituting Cd sites on Cu2CdSnSe4 are prepared by the melting method and the spark plasma sintering (SPS) technique to form Cu2Cd1-xMnxSnSe4. Our experimental and theoretical studies show that the moderate Mn doping by substituting Cd sites is an effective method to improve the thermoelectric performance of Cu2CdSnSe4. The electrical resistivity is decreased by about a...

To develop the combustion characteristics of aluminum powder in steam, the ignition and combustion process of aluminum powder with different additives (KBH4, ammonium perchlorate (AP) and NaCl) addition at different levels were studied using a transparent pipe furnace. The temperature variation of these samples was measured using a thermocouple, and a high-speed camera was used to record combus...

The sweat test still is the pivotal test for the diagnosis of cystic fibrosis (CF), even in the era of genetic testing based on genome DNA analysis. The classic technique by Gibson & Cooke, 1 which still is considered the gold standard for sweat testing, has been repeatedly criticized because of its complexity, which restricts access: the complications of this technique include the need to elut...

Mitochondria play an essential role in reactive oxygen species (ROS) signal transduction in plants. Redox regulation is an essential feature of mitochondrial function, with thioredoxin (Trx), involved in disulphide/dithiol interchange, playing a prominent role. To explore the participation of mitochondrial PsTrxo1, Mn-superoxide dismutase (Mn-SOD), peroxiredoxin (PsPrxII F), and alternative oxi...

This work aimed to evaluate the physiological behavior and growth of jurema-preta seedlings under salinity conditions. The experiment was conducted at Forestry Nursery Academic Unit Engineering/UFCG, with plants kept in 'Leonard' pots. treatments were distributed a completely randomized design, five levels electrical conductivity (EC) nutrient solution (0.5; 2.0; 3.5; 5.0 6.5 dS m-1) four repet...

Road salt deicers, especially NaCl and CaCl2, are increasingly applied to paved areas throughout the world. The goal of this study is to investigate the influence of high concentrations of these salts on wetland biogeochemistry. Sediment cores were collected in fall and spring from a freshwater wetland fringing an urban kettle lake (Asylum Lake, Kalamazoo, MI, USA), and incubated for 100 days i...
