Among the most important quality parameters of irrigation water used for greenhouse crops, alkalinity of water is considered critical due to its impact on pH of soil or growing medium solution. In this study, shoot and root Fe contents and SPAD index were investigated in non-grafted and grafted tomato (greenhouse tomato) plants onto five rootstocks (eggplant, datura, orange nightshade, local Ir...
The short-term consumption of foods that differed in energy density (ED) and/or NaHCO3 supplementation, on subsequent food intake and diet selection in sheep were measured. Thirty sheep weighing 35.9 (sd 2.89) kg were used. Two foods were formulated: H had 11 and L had 8 MJ metabolizable energy/kg fresh matter. Four further foods were formulated by adding either 40 g NaHCO3/kg or 16.5 g NaCl/kg...
Morphologically controlled Pd-based nanocrystals are the most efficient strategies for improving electrocatalytic ethanol oxidation reaction (EOR) performance; however, their morphological-EOR activity relationship and effect of electrolytes at a wide pH range still ambiguous. Here, we have synthesized porous self-standing Pd clustered nanospheres (Pd-CNSs) nanocubes (Pd-NCBs) EOR in acidic (H2...
Farmers that cultivate tomatoes use imidacloprid to combat sucking bugs even while the fruits are being harvested so they can maintain a five- six-time harvest. Decontaminating tomato before eating is absolutely necessary due insecticide's slow dissipation rate and fact residues last in vegetables for 15–25 days. The quality of fruit has been compromised cannot be used salads, despite various h...
منابع کربن و نیتروژن از عوامل ضروری برای رشد ریز جلبکها محسوب میشود، در این مطالعه اثر سدیم نیترات (NaNO3) و سدیم بیکربنات (NaHCO3) بر رشد ریز جلبک N. oleoabundan در محیط کشت BBM موردبررسی قرار گرفت. بدین منظور از محلول NaNO3 با غلظت های (0، 5/0، 1، 5/2، 5، 10) گرم بر لیتر و محلول NaHCO3 با غلظت های (0، 25/0، 5/0، 75/0، 1، 25/1) گرم بر لیتر در محیط BBM طی مدت زمان21 روز استفاده گردید. نتایج...
This paper explores the ability of Chlorella sp. and Scenedesmus to convert landfill leachates into usable metabolites. Different concentrations (0.5, 1, 5, 10% v/v) leachate coupled with an inorganic carbon source (Na2CO3, NaHCO3) were tested improve biomass production, metabolites synthesis, removal NO3 PO4. The result shows that both strains can effectively grow in media up 5% (v/v) leachate...
Introduction Acidosis is a frequent disorder among critically ill patients. When patient compensatory responses fail to restore a normal pH, administration of sodium bicarbonate (NaHCO3) or renal replacement therapy may be required. Intravenous NaHCO3 increases plasma Strong Ion Difference ([SID] = [Na] + [K] [Cl]) and HCO3 concentration by raising Na concentration. Although effective, this tre...
The effect of NaHCO2 on the growth of Neisseria gonorrhoeae cultures was studied in a liquid and a semisolid growth medium. With a broth culture, NaHCO3 (0.009 M) greatly reduced the lag phase and also increased the total growth. The same concentration of bicarbonate supported rapid growth when added to the semisolid medium if the plates were individually incubated in sealed plastic bags. In a ...
Driven by their many unique features, perovskite solar cells (PSCs) have become one of the most promising candidates in photovoltaic field. Two-step preparation film is advantageous for its higher stability and reproducibility compared to one-step method, which more suitable practical application. However, incomplete conversion dense lead iodide (PbI2) layer during sequential spin-coating forma...
In order to evaluate the effect of inert powder on ignition sensitivity sucrose dust, this study investigated effects NaHCO3, NaCl, NH4H2PO4 and Al(OH)3 minimum energy (MIE) dust. The results showed that all four different powders inhibited MIE them a trend smaller particle size powders, better inhibition effect. was ranked as NaHCO3 > NaCl Al(OH)3. had both physical chemical effects, which ...
