Hydrogen-bonded organic frameworks (HOFs) are crystalline porous polymers which formed by the interaction of hydrogen bonding among building blocks. Unique advantages HOFs, enabling new platforms for exploring multifunctional applications.
Organic thin-film transistors (OTFTs) are a promising technology for large-area electronics; choosing an appropriate circuit style is critical to enhancing OTFT functionality and reliability. Here, we design evaluate different types of static dynamic logic based on complementary p-type only styles, benchmarking their performance under equivalent processing testing conditions. We find that diffe...
date palm tree reaction to fertilizer is very slow, due to the trunk nutrients. this fact leads to farmer unwillingness to feed the trees. however, balance fertilizing improves vegetative growth and reduce the period for flowering. this study aimed to assess the effects of manure, chemical and organic sulfur on vegetative characteristics of ‘piarom’ date palm offshoot in a randomized complete b...
this experiment was conducted to evaluate and compare antibiotic, organic acid, probiotic and prebiotic effects on performance, egg quality and blood metabolites in commercial laying hens. the experiment was a completely randomized design with 160 laying hens strain hy line (w-36) from 32 to 42 weeks of age with 5 treatments and 4 replicates of 8 hens each. the experimental treatments consisted...
in order to study the effect of different organic fertilizers on quantitative and qualitative characteristics of fenugreek forage, an experiment was conducted based on completely randomized block design with six treatments and three replications at agricultural research station, college of agriculture, ferdowsi university of mashhad, iran, during 2006. the experimental treatments were four orga...
background & aim: in sustainable agriculture, organic fertilizers are considered as important alternatives for chemical ones and are of great importance in organic producing of medicinal plants. this study was conducted to study the effects of organic fertilizers on cassia angustifolia vahl in dry and subtropical climate. experimental: this study was carried out in jiroft region, kerman (i...
abstract soil drying and rewetting (drw) cycles are considered as environmental stress that would affect the physical, chemical and biological properties of soil and nutrient cycles. the study of soil drying and rewetting effects on plant nutrition and soil fertility is very important and crucial specially their environmental effects. in this study, the effects of 1, 2, 3, 4 and 5 drying and re...
the high cost of fertilizers in farming systems, soil pollution and degradation of soil are factors that caused to full use of available renewable nutrient sources of plant (organic and biological) with optimal application of fertilizers in order to maintain fertility, structure, biological activity, exchange capacity and water-holding capacity of the water in soil. therefore, in recent years, ...
application of organic manures is one of the most important strategies for plant nutrition compared to chemical fertilizers, especially in organic management of medicinal plants. in order to evaluate the effects of different organic and chemical fertilizers on yield, yield components and qualitative characteristics of isabgol (plantago ovata), a field experiment was conducted based on randomize...
