Morphological and physiological behavior in soybean (Glycine max) genotypes to drought stress implemented at pre- and post-anthesis stages

In order to evaluate the morphological and physiological responses of soybean genotypes to water deficit, a field experiment with 3 different soybean genotypes at three different irrigation regimes was carried out. Plants were grown either under optimum condition (irrigated), drought stress implemented before the flowering (pre-anthesis) and pod-filling stage (post-anthesis). Seed yield and measured morphological characters, except for number of seeds per plant and seed protein content, decreased from normal irrigation regime to water deficit stress in both flowering and pod filling growing stages. Leaf relative water content (RWC) was significantly decreased in all genotypes by water deficit at both growing stages, as well as both stressed environments had progressive fall in chemical osmolytes and chlorophyll content. With the present results, it can be concluded that drought stress retards the growth and metabolic activity of soybean genotypes. These parameters showed considerable variability under drought stress at different growth stages in soybean

El impacto del factor ambiental en el desarrollo económico de Kerman durante el Ilkanato

Natural phenomena are one of the influencing factors in the economic and social situation of human societies. However, it is clear that the mode and extent of this effect depends on the natural state of this or that area. On the other hand, Iran's historical events and circumstances appear to have been less studied geographically. The present study examines the probable impact of the natural phenomena of the Kerman province, their prominent and diverse natural and human characteristics on the sources of the Iakhanan period. For this purpose, it uses the historical and geographical reports of the 7th and 8th centuries. The above findings are important in this regard, demonstrating the history of economic developments in Kerman and other parts of Iran should not affect only in light of human events.Los fenómenos naturales son uno de los factores influyentes en la situación económica y social de las sociedades humanas. Sin embargo, está claro que el modo y el alcance de este efecto depende del estado natural de esta o aquella área. Por otro lado, los eventos y circunstancias históricas de Irán parecen haber sido menos estudiados desde una perspectiva geográfica. El presente estudio examina el probable impacto de los fenómenos naturales de la provincia de Kerman, sus características naturales y humanas prominentes y diversas en las fuentes del período Iakhanan. Para este propósito, se sirve de los informes históricos y geográficos de los siglos VII y VIII. Los hallazgos anteriores son importantes a este respecto, lo que demuestra que la historia de los desarrollos económicos de Kerman y otras partes de Irán no deben considerarse solo a la luz de los acontecimientos humanos

Discrete wavelet transform and artificial neural network for gearbox fault detection based on acoustic signals

Gearboxes are widely applied in power transmission lines, so their health monitoring has a great impact in industrial applications. In the present study, acoustic signals of Pride gearbox in different conditions, namely, healthy, worn first gear and broken second gear are collected by a microphone. Discrete wavelet transform (DWT) is applied to process the signals. Decomposition is made using Daubichies-5 wavelet with five levels. In order to identify the various conditions of the gearbox, artificial neural network (ANN) is used in decision-making stage. The results indicate that this method allow identification at a 90 % level of efficiency. Therefore, the proposed approach can be reliably applied to gearbox fault detection

Translation and Psychometric Validation of Women Health Questionnaire (WHQ) in Persian Language

Menopause is not a disease; however the somatic and psychological symptoms that accompany it affect the life of women. Women health questionnaire (WHQ) is a self-administered questionnaire that measures the physical and mental health of women ages 40 to 65 years. The purpose of this study is to provide psychometric documentation details of the translation of WHQ into the Persian language. A total of 350 peri and postmenopausal women were recruited from urban health centers in the city of Tabriz, between March and October 2015. The validity of WHQ was assessed using construct and discriminate validity. The reliability of questionnaire was assessed by test retest reliability and measuring internal consistency. The KMO was 0.791, and the Bartlett’s test of Sphericity was significant. Principle component analysis (PCA) resulted in 9 factors which explained up to 55.4% of the total variance. Cronbach's coefficient was 0.799 and the Intraclass correlation coefficient (ICC) of the Persian translation scale was 0.712. Evaluation of the psychometric properties showed that the Persian language translation of the 36-item version of the WHQ was appropriate when applied to middle aged wome

A New Performance Metric for User-preference Based Multi-objective Evolutionary Algorithms

Abstract—In this paper, we propose a metric for evaluating the performance of user-preference based evolutionary multiobjective algorithms by defining a preferred region based on the location of a user-supplied reference point. This metric uses a composite front which is a type of reference set and is used as a replacement for the Pareto-optimal front. This composite front is constructed by extracting the non-dominated solutions from the merged solution sets of all algorithms that are to be compared. A preferred region is then defined on the composite front based on the location of a reference point. Once the preferred region is defined, existing evolutionary multi-objective performance metrics can be applied with respect to the preferred region. In this paper the performance of a cardinality-based metric, a distance-based metric, and a volume-based metric are compared against a baseline which relies on knowledge of the Pareto-optimal front. The experimental results show that the distance-based and the volume-based metrics are consistent with the baseline, showing meaningful comparisons. However, the cardinality-based approach shows some inconsistencies and is not suitable for comparing the algorithms. I

The evaluation of two promising rainfed wheat cultivars as affected by different seeding rate in conventional and conservation tillage systems

This experiment was conducted to evaluate of two promising rainfed wheat cultivars as affected by different seeding rate in conventional and conservation tillage systems in the research field of the Dryland Agriculture Research Institute (DARI), Sararood branch, Kermanshah, Iran. The experiment layout designed as strip-split plot in a randomized complete block design with 3 replications during two consecutive growing seasons 2017-18 and 2018-19. The tillage systems were placed next to each other as a separate site at two levels: conventional tillage and conservation tillage (no tillage). Wheat cultivars were performed horizontally at two levels (Baran and Rijaw) and the seeding rate was carried out vertically with eight levels (75, 100, 125, 150, 175, 200, 225, 250 kg/ha). The combined results indicated that no-tillage increased soil organic carbon by 0.18% but decreased non-significant grain yield by 18.2% via reducing yield components. In this experiment, a significant difference was observed between cultivars in terms of yield components, but the grain yield was not significant. Comparison of different seeding rate also showed a significant difference between all studied traits except the number of seeds per spike and grain yield. Also the maximum protein content achieved in conventional tillage, Baran cultivar and seeding rate of 75kg/ha. Finally, based on the results of interactions, the maximum grain yield was obtained by conventional tillage, Rijaw cultivar and seeding rate of 175 kg/ha as 2293.7 kg/ha, while the low yield was achieved in the no tillage, Baran cultivar and the seed rate of 75 kg/ha as 1323.02 kg/h
