Abstract: 

In severely eroded areas, especially steep slopes, establishment of vegetation cover is not possible. The application of organic and inorganic amendments can therefore improve the conditions leading to establish vegetation cover through playing an effective role in runoff CONTROL. Accordingly, in the present study, woodchips as a soil organic amendment was applied to CONTROL runoff variables including time to runoff, runoff volume and coefficient. For this purpose, three levels of woodchips treatment of 0.5, 1.0 and 1.5 kgm-2 were used in three replications at in 1 m2- PLOT scale. The PLOTs were located in 30% slope in accordance with field conditions under simulated rainfall of 60 mmh-1 and duration of 15 min. The results showed that application of woodchips in 0.5, 1.0 and 1.5 kgm-2, time to runoff increased 97.50, 192.38 and 203.31%, respectively. The runoff volume decreased 35.23, 55.11 and 60.43% and runoff coefficient also decreased 42.43, 67.40 and 72.14% in three levels of woodchips treatments, respectively. The results of GLM showed that woodchips treatment had a significant increasing effect on time to runoff (p≤0.01) as well as a significant decreasing effect on runoff volume and coefficient (p≤0.05). The application of woodchips as a conservation treatment on the soil surface showed that this amendment can be used for runoff CONTROL especially where large quantities of woodchips are simply available.

Abstract: 

A common method for CONTROLling a group of parallel converters in decentralized CONTROL strategy structure in an island microgrid, the use is the droop-down characteristics of frequency ω-P and voltage E-Q. However, the problem with using this method is that the reactive power is not properly distributed (in proportion to the capacity of the micronutrients) between the micronutrients, which may lead to overload in the converters. Microgrids may also suffer from dynamic stability problems such as power fluctuations, which can be increased by switching between active and reactive power CONTROL. To avoid this problem, the X / R ratio of transmission lines is an important parameter that should be carefully considered in the design of micronutrient CONTROLlers. By linearizing and simplifying conditions, the CONTROL system conversion function model becomes a single input-single output system, which is efficient enough to show the relationship between CONTROL parameters such as slope of droop characteristics and derivative sentences, virtual impedance, and voltage CONTROLlers. Using this model, stability conditions for different parameters are analyzed. Also, to improve power distribution stability, common droop strategies are modified by adjusting the slope as well as adding nonlinear sentence sections. This approach reduces the coupling between active and reactive power CONTROL and reduces the dependence of power distribution on grid parameters such as the X / R ratio. To evaluate the reliability of the proposed model, the simulation results in a sample island microgrid in MATLAB software are presented.

Abstract: 

What structuralist narratologists have in common is that, instead of analyzing the actants of a literary genre based on traditional rhetoric, they analyze a literary genre as a systematic structure whose actants have internal links together. The PLOT or the sequence of events is the most significant element that both the first and the second generation of Narratologists have considered attentively. Although the first generation emphasizes on causative and effective sequence, the second generation, especially, Raymon Kenon, has also added the periodic sequence to that. The present study aimed at considering 300 Sufis’ revelations selected from 30 mystical prose from the 4th to the 7th Century. It was found that even though the combination of events had numerous superficial differences, they followed few similar patterns. The results also showed that, in addition to the causative or periodic relevance, the revelations had another kind of sequence whereby a unique moment of the mystic’s incoming is briefly narrated. These kinds of revelations are highly inspired by a type of French story which is called “Nouvelle - instant” revelation.

Abstract: 

Gaps within forest canopy cause changes in the received amount (intensity) and quality (PAR) of incoming light on forest ground. This research was performed in natural gaps of a reserve CONTROL compartment at Kelardasht region in Mazandaran, northern Iran and aimed to determine the role of gap size and relative light intensity on soil enzyme activity. Hence, 14 gaps at four size class (<200 m2- 200-300 m2- 300-400 m2 and>400 m2) and four light classes (<8 %- 8-17 %- 17-25% and>25 %) were selected. Soil was sampled at 0-20 cm of top soil in the center of each gap. The results showed significantly different dehydrogenase activity in classes of gap size and light intensity, where its maximum amount was observed in the large gap size (300-400 m2) and at low light intensity (<8%), respectively. Urease activity did not show significant difference within the classes. In addition, relative soil moisture was significantly different across the gap size and light intensity classes, whereas organic matter and Nitrogen did not show to be significant different.

Abstract: 

hariri and hamidis amqamat ,as two prose works in classical Arabic and Persian literature have special values for the critics. The study of "PLOT" in these two literary works illustrates that hariri had prepared an attractive and independent sketch for each short story (amqamat) in advance each to be employed for a macrostructure. hamidis however failed to follow what hariri did in this respect. as a result his short stories are know to have failed in matching those of the hariri both in attraction and an organized sketch.

Abstract: 

In order to study the effect of PLOT-to-PLOT irrigation method on soil chemical characteristics and rice yield, a randomized block experiment was conducted in the research farm of the Faculty of Agricultural Sciences of University of Guilan. This research was done in three repetitions and each repetition included six PLOTs which were named PLOT by PLOT in a vertical row from 1 to 6. The quality characteristics of the soil were evaluated at two depths of 0 to 15 and 15 to 30 cm, as well as grain yield. The results showed that the highest salinity (3.8 mmhos/cm), total soluble solids (2316.6 mg/l), nitrate (6.3 mg/l), sodium (407.5 mg/l), calcium (410.8 mg/L), and sodium absorption ratio (5.6 me/L) were observed at the depth of 0 to 15 cm in the sixth PLOT. But, the highest grain yield with 9035.54 kg/ha was related to the fourth PLOT. Despite the same agricultural operations in the PLOTs, the amounts of nutrients, soil soluble salts and grain yield were different in them, which could be due to the difference in the amount of nutrients in the PLOTs. Therefore, in order to prevent their amount from changing from one PLOT to another, the necessary opportunity for the absorption of water nutrients and soil solution by the plant in the PLOTs should be created to affect the final yield. In general, due to the reduction of only 5.92 and 4.33 percent of paddy yield in the sixth PLOT compared to the fourth and first PLOTs, respectively, it seems that due to the limited water resources in the north of the country, the use of PLOT-to-PLOT irrigation for planting Rice needs more and more detailed investigation in order to achieve the highest growth and yield in the region.

Abstract: 

"PLOT" is one of the main elements of stories and the most important assessment criteria of aestheticism in an anecdotal work. The holy Qur'an is full of narratives whose belletristic could be assessed on the basis of modern yardsticks. In this research, the PLOT of Yousef's story has been studied and analyzed based on Larivey's theory.Among the specialized features of the PLOT of the proposed story, one can point to aspects such as the exact management and the suitable selection of information, the creation of paradox and the gradual abeyance in the least voluminous text, congruence of actions and unity of incidences, and homogeneity in the narrative with respect to occurrences.
