This research examines the lexical processing of head-first endocentric compounds in Persian based on semantic transparency. This study shows whether the processing is related to the morpheme-based, whole-word, or dual-root models. Moreover, this research concludes whether the processing is associated with sublexical or supralexical models. Two separate masked priming tasks are conducted. In the first experiment, the compound word is the primed word and the modifier is the target. In the second experiment, the prime is the compound word and the target is the head. Three conditions are considered: transparent, opaque, and orthographic-overlap. In order to analyze the result, mixed models are used. The results show significant priming effects for transparent and opaque conditions. While no priming effect is shown for the orthographic-overlap condition. It can be concluded that the lexical processing of head-first endocentric compounds is independent of semantic transparency. The processing is morpheme-based and it is on the basis of the sublexical model. Furthermore, the semantic processing of these words is supralexical. Moreover, the lack of priming effect for the orthographic conditions is seemingly associated with orthographic complexity in the Persian writing system.

Prangos ferulacea (L.) Lindl. (Umbelliferae family) is a dominant species in the some partial of habitats in Zagros Mountains. According to ethno-botanical studies, this plant is one of the best range plants of Iran. Local ranchers collect green Prangos while it is toxic. They then dry the plant and use it to feed their livestock, especially in winter season. This research done to analyse the changes in the chemical composition of Pr. ferulacea with the effects of time, location and type of secondary metabolisms. Therefore, the ingredients and amounts of the essential oils of Prangos were studied during the growing and flowering stages (in both green/fresh and dried forms) to track such changes. The results showed that the amounts of terpinolene, β-phellandrene and bornyl acetate were decreased in the dried form, and some of the harmful components, such as α-pinene, β-pinene, myrcen and delta-3-carene, were absent, rendering the plant non-toxic. These results confirm the opinion of the ranchers. In the growing stage, the amount of coumarin was significantly less than in the flowering stage, which also supports the conduct of the local ranchers who gather the plants at the most appropriate time.

The biocontrol activity of two isolates of Candida membranifaciens against grey mold of apple fruit caused by Botrytis mali and their ability to induce biochemical defense responses in apple tissue were investigated. Apple fruit (Malus domestica) wounds were inoculated with 50 µl yeast suspension (1 × 10⁷ CFU/ml) of C. membranifaciens followed 4 h later by 20 µl of conidial suspension of B. mali (1 × 10⁵ conidia/ml). The apples were then incubated at 20 ºC for 8 days. Lesion diameter sizes were measured 4 and 8 days after pathogen inoculation. In addition to controlling grey mold, these two isolates of C. membranifaciens caused increases in peroxidase and β-1, 3-glucanase activities. These isolates also caused inhibition in catalase activity. The accumulation of phenolic compounds was increased in apple fruit treated with antagonists and inoculated with B. mali and reached its highest level 6 days after treatment. The ability of C. membranifaciens to affect H2O2-metobolizing enzymes and increase levels of β-1, 3-glucanase activity and phenolic compounds may be some of mechanisms responsible for its biocontrol activity.

The present paper is an attempt to investigate the methods of passivisation of Persian compound verbs on the one hand and, to introduce Jackendoff’s semantic theory; which is called Theory of Conceptual Semantics on the other. The purpose of introducing this theory is to check Persian data within the framework of this theory to see if the its foundations, as its founder claims, are universal and can justify Persian data or not. To do this, the semantic behaviors of 22 Persian compound verbs were examined when making them passive. There are two methods for the passivization of Persian compound verbs, namely syntactic and semantic. Since the Jackendoff’s semantic theory is unable to explain the unacceptability of grammatical sentences, because the approach it takes for semantic analysis is making semantic components salient, thus we will reason that if sentence is not considered as the unit of semantic analysis, the outputs of such analysis will not be correct.

Most previous laboratory studies of local scour at bridge abutments were performed in rectangular channels in which the distributions of flow velocity and bed shear stress were considered uniform in the transverse direction. In reality however, bridge abutments are usually located in the floodplain zone of rivers where velocity and shear stress distributions are directly affected by the lateral momentum transfer. The influence of channel geometry and lateral momentum transfer in compound flow field on scouring phenomenon, however, has not been fully investigated and understood as yet. This paper presents the results of an experimental study performed to investigate the impact of both sediment size and lateral momentum transfer on local scour at abutments terminating in the floodplain of a compound channel. It is shown that, by accounting for lateral momentum transfer at small floodplain/main channel depth ratios (yalH<0.3), estimates of maximum local scour depth are increased by up to 30% . In relation to the sediment size, earlier studies of scouring around circular bridge piers proposed a limit for the relative size of sediment (pier diameter/median size of bed material) beyond which the sediment size has no effect on the equilibrium scour depth (Ettema, 1980; Chiew, 1984). The results of the current laboratory studies, however, indicated that the limit established for circular bridge piers might not be appropriate for the abutment case installed in the floodplain zones; further studies are required to draw a more general conclusion regarding the effects of relative grain size in the abutment case.

Research subject: In recent years, there are so many attractions in the field of effective detection and discrimination of volatile organic compounds (VOCs). Detection of VOCs compounds, are very important in many applications and industries such as air pollution control, air quality control, food packaging, food quality control, disease diagnostic, agriculture etc. The sensitivity and selectivity of the prepared sensors to detect of VOCs needs to improve.   
 Research approach: A conductive polymer composite sensitive layer based on poly (lactic acid) as polymer matrix and multiwall carbon nanotubes as conductive filler was prepared to detect of volatile organic compounds (VOCs). For this purpose the porous sensitive layer was prepared by non-solvent induced phase separation (NIPS) method. In this structure, chloroform (low boiling point temperature) was used as the solvent and ethanol (high boiling point temperature) was used as a non-solvent. The sensitive layer was used to detect of toluene, methanol, and chloroform. The structure and morphology of synthesized layer was investigated by means of scanning electron microscopy (SEM) and BET test.
Main results: The investigation indicated that the phase separation method induced the open cell morphology into the conductive composite. The BET results showed that the specific surface area of composite increased to 22.3 m²/gr. The experimental results showed that the response properties of porous layers was improved dramatically in comparison with dense layers. It was related to the increase of specific surface area of polymer composite and therefore the increase of diffusion coefficient of analyte molecules into the polymer matrix. Finally the sensitivity and selectivity of porous sensitive layers was investigated based on Flory-Huggins interaction parameter.

Collocation is the utilization of two or more words, often with a high frequency, with one another, provided that the frequency should be significant enough in order not to be labeled accidental. This linguistic phenomenon has been attracting several translation scholars contemporarily; stimulating them to closely scrutinize and observe the translation of these collocations in different books. This study, with the help of a descriptive and analytical method, aims to study these adjectival and genitive collocation and its translations in the Holy Quran. In the first place, 55 adjectival and genitive collocations from the Quran and its ten contemporary translations were extracted which were later criticized and analyzed. The results of the study indicate that the translation ignorance of these Quranic collocations, as units of translations, have not only brought about various translations of the same collocations, but also has lead to the emergence of the same form of translation of various collocations with different meanings. In conclusion, some suggestions to remove these challenges have been offered. For instance, prefabricated equivalences for these collocations could be prepared to be referenced to in order to come up with translations which are along the same lines.

The effects of mucal proteins of sea anemone, Stichodactylahaddoni,on different stages of embryonic development of zebra fish (D. rerio) were examined. The sea anemone samples were collected from the intertidal areas of the Hormuz Island (Persian Gulf), and were frozen at -160 °C. Protein and peptide components were extracted by 100% methanol. Following the total protein assessment by ELISA, three concentrations (2.1, 3.7 and 7.4 mg/ml distil water) were prepared. From each concentration, 2 ml was added to the microplates containing 150 zebra fish eggs each, with 2 replications; microplates with normal aquarium water was also used as control group. The eggs were incubated for 72 hrs and the process of embryonic development was observed every 6 to 12 hours. Results showed that the embryonic development was normal in the control group, while the eggs treated with 3.7 and 7.4 mg/ml ofmucal proteins degenerated and blackened in less than 12 hours. Also a delay in the phase of growth in embryonic development was observed in the group with 1.2 mg/ml of protein. Our results showed that the mucal proteins from this sea anemone can affect embryonic development rapidly, causing delayed growth at low concentration, and cell lysis and embryonic degeneration at high concentrations.

Compounding is one of the subjects, which have been always under research in the history of linguistic studies from different aspects. In the area of semantics of compounds, due to the principle of semantic compositionality that unites the meaning of components of a compound to reach out a compositional meaning, we find endocentric compounds with a semantic head. On the other hand, there are plentiful of compounds in a language, which have no semantic head and, consequently, no compositionality. Therefore, we find the referent of the compound out of it, which should be listed in lexicon and to be memorized. Exocentric compounds with no clear semantic head and no compositionality have opaque meaning. Based on the claims of Carin’s theory, which has a cognitive approach, we could explain that the reason that a compound is transparent or opaque in meaning is due to the existence or lack of a semantic relation. The very semantic relation that Carin’s theory recognizes as the key entity for interpretation is at the same time responsible for a compound being transparent or opaque. In endocentric compound, the relation existing between head and modifier creates the focal concept in the compound. In fact, by this semantic relation, we come to interpret noun compound even if we face with it for the first time. Having or not having a semantic relation for a compound is the key explanation behind the semantic transparency and opacity.

Some plant extracts have been reported to exhibit antimicrobial properties. Plant based pesticides appear to be an alternative for the synthetic pesticides because of their less dangerous impacts. The objective of this study was to assess the inhibitory activity of Brassica napus water extract on mycelial growth of six phytopathogenic fungi Rhizoctonia solani, Phythophtora drechseleri, Pythium aphanidermatum, Verticellium dahliae, Fusarium oxysporum, and Gaeumannomyces graminis. Antifungal activity test was performed by disc diffusion method. Concentrations of 100 and 50 ppm had the highest and the lowest inhibitory effects on all studied species respectively. The shoot extract (SE) was significantly exerted higher antifungal activity than root extract (RE). At 100 ppm, V. dahliae (17.02% inhibition by RE) and F. oxysporum (50% inhibition by SE) were the most sensitive species however, R. solani (1.8 and 15%) was the most resistant fungus to both extracts. Active compounds of B. napus extract were determined by high performance liquid chromatography (HPLC). Phenolic compounds had the highest concentrations in extracts and are probably the main cause of the mycelial growth inhibition. Application of canola aqueous extract or incorporation of canola in crop rotation program can be considered as a method for management of some soil-borne phytopathogenic fungi.

Additional compounds are sort of issues that are studied in both Russian and Persian languages in terms of nominal groups. Some linguists and grammarians of Persian language relate additional compounds (though without prepositions) to noun complements. Additional compounds represent various concepts and features such as ownership, identity, gender expression and allocation. These compounds in Persian language are stated by adding a noun to another noun, which the equivalent expressions in Russian language are consistent (определение согласованное) and inconsistent (несогласованное определение) noun affiliates. The aim of this study is to evaluate additional compounds in Persian and Russian languages in terms of syntax, and to find the possible similarities and harmony, between them. Finally, the ways to express the same meanings in the different structures of these compounds are discussed.

In this paper, we examine the effect of the energy difference between the L- and the -valleys in compound semiconductor materials, carrier effective mass, and the scattering processes on the electron transport characteristics in MESFETs. To do this, we use the Monte Carlo simulation to demonstrate the superiority of the InGaAs MESFET, made on a semi-insulating InP substrate, over both InP and GaAs MESFETs. Furthermore, we study the effects of device structure on the electron transport characteristics. For the first time we study electron transport characteristics in the channel of a LDD InGaAs MESFET with an InP source. This structure demonstrates to have the highest average electron velocity through out its channel among the other MESFETs

Solvent extraction and taguchi method were used to optimize conditions for the antioxidant activity of Azolla fern extracts. The independent processing variables were ethanol concentration, extraction time and solid to solvent ratio. Ethanol concentration and solvent to solid ratio significantly affected antioxidant activity measured by the total phenol content (p < 0.05). whereas the extraction time did not significantly affect the activity (p > 0.05). Antioxidant activity of the extracts, determined by the total phenolic content, varied from 5.77 to 16.42 mg acid gallic equivalents/g of dry sample. DPPH scavenging activity percentage ranged from %20.51 to %93.71. Ethanol concentration of %50 and sample to solvent ratio of 1 to 15 were optimal for the highest antioxidant activities measured by the TPC assay and the DPPH method. The optimal extraction time was 48h. The result show that azolla fern is suitable for antioxidant extraction.

The fungal genus Paecilomyces comprises numerous pathogenic and saprobic species, which are regularly isolated from insects, nematodes, soil, air, food, paper and many other materials. Some of the Paecilomyces species have been known to exhibit capabilities for curing human diseases. Here, bioactivities of metabolites from some soil inhabitant and invertebrate pathogenic Paecilomyces species were explored against a panel of target prokaryotic and eukaryotic microorganisms. First, Petri plate assays indicated that all tested Paecilomyces species were capable of producing diffusible metabolites and volatile compounds with antifungal activities against Pyricularia oryzae and Saccharomyces cerevisiae. Subsequently, the metabolites of the Paecilomyces species were extracted and the growth inhibitory and antimitotic effects of extra-cellular metabolites were shown using the yeast S. cerevisiae as a model. Further research indicated some antibacterial activity of extra-cellular metabolites from Paecilomyces species against human pathogenic bacteria Staphylococcus aureus, Bacillus subtilis, Streptococcus pyogenes (G⁺) and Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi (G^-). These findings indicate that the Paecilomyces species, either saprobic or pathogenic, have a strong arsenal of bioactive metabolites which show inhibitory or cytotoxic effects against other microorganisms, with a potential for application in agroforestry and medicine.

  In this experiment, acetone was used to extract the phenolic compounds of grape pomace by colorimetric method (Folin-Ciocalteu). The phenolics extract levels of 50, 150, 250 and 350 ppm were used to assess their antioxidant activity in raw soybean oil. On day 0, 4, 8 and 12 the proxide value for soybean oil was estimated. Also, the TBA value for soybean oil on day 0, 5, 9 and 13 was estimated. The results showed that the phenolic compounds whose content in grape pomace is 64 g/kg DM has an antioxidant activity. The level of 150 ppm of tannin extract from grape pomace showed a desirable activity to prevent the oxidation of raw soybean oil. The antioxidant activity of this level was higher than those obtained by the level 200 ppm from synthetic antioxidants. Therefore, the use of phenolic compound in grape pomace as natural antioxidants can be recommended.

Aims: The aim of this study was to investigate chemical composition, antioxidant potential, and antimicrobial activity of cardamom essential oil against Staphylococcus aureus, Escherichia coli, and Saccharomyces cerevisiae species.
Materials & Methods: The chemical compositions of cardamom essential oil were identified by Gas Chromatography-Mass Spectrometry (GC-MS) device. Cardamom essential oil antioxidant activity was measured by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay, and its total phenolic compounds (TPC) were measured by Folin–Ciocalteu reagent. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of cardamom essential oil were determined using the serial-dilution method.
Findings: According to the GC-MS analysis results, 17 compounds were totally identified in cardamom essential oil, among which the most important compounds were 1, 8-cineole (36.74%) and α-terpinyl acetate (33.07%). MICs obtained for S. aureus, E. coli, and S. cerevisiae were 12.50, 25.00, and 1.56 mg/mL, respectively. Also, MBC obtained for both S. aureus and E. coli was 25 mg/mL, while MBC for S. cerevisiae was 3.36 mg/mL. Antioxidant activity measurement results showed that increasing the amount of cardamom essential oil reduced the amount of color and absorbance of DPPH solution to 517 nm. The results also showed that the amount of TPC in cardamom essential oil was 214.35 mg gallic acid per 100 g of dry material.
Conclusion: Cardamom essential oil used in this study showed antibacterial and anti-yeast activities against S. aureus, E. coli, and S. cerevisiae species. Antimicrobial effects of cardamom essential oil were predictable due to the presence of antimicrobial components in this oil.

Free radicals, having one or more unpaired electrons in the outer orbit, which are oxygen-centred free radicals, sometimes known as reactive oxygen species (ROS). The oxidative stress imposed by ROS plays an important role in many chronic and degenerative diseases. The aim of the present research was undertaken to study the antioxidant activity and polyphenolic content in the different extracts of sea urchin Echinometra mathaei. Different extracts (spine, shell, gonad and aristotol lantern) of sea urchin were isolated by three solvents (n- hexan, ethyl acetate, methanol). Antioxidant activity of extracts was assessed by measured reducing power, DPPH free radical scavenging activity and total antioxidant capacity assays, and compared with the synthetic antioxidant butylated hydroxytoluent (BHT) and Ascorbic acid. Total phenolic and flavonoid contents were measured spectrophotometrically. According to the results of the study, highest the reducing power and free radical-scavenging activity of the methanolic shell and methanolic spine, respectively. In total antioxidant capacity assay, the antioxidant activity of aristotol lantern ethyl acetate, spine and gonad n-hexan was higher as compared to that of the ascorbic acid. The highest total phenol and flavonoid compound content per gram of the methanolic spine were 0.0044±0.0003 mg gallic acid equivalents and 24.616±0.7167 mg quercetin equivalents, respectively. Significant differences were observed at P

The extraction of hydrocolloids from seaweeds is associated with production of secondary metabolites during pretreatment step. In this study, the antioxidant properties were evaluated for secondary metabolites from brown seaweed S. angustifolium. The crude extract obtained by 80% ethanol for four hours and then partitioned using hexane, chloroform, ethyl acetate and water. The extraction yield was found to be 4% for crude extract and varied between 2.8-43% for fractions. The evaluation of antioxidant properties revealed a successful solvent fractionation in portioning antioxidant compounds. Among various fractions, ethyl acetate exhibited the highest activity in DPPH radical scavenging (75.78%), ABTS radical scavenging (88.92%), reducing power (67.54%) and total antioxidant (0.34 Abs) capacities. The highest amount of phenolic contents was found in ethyl acetate fraction (277.86 mg/ TA in extract) while the lowest amount was in aqueous fraction (21.36 mg/ TA in extract). The highest correlation (R² = 0.88) was observed between total phenolic content and total antioxidant activity. Overall, the results of current study show that ethanol extract of S. angustifolium contains major bioactive compounds suggesting its potential application in food industry as a natural antioxidant.
