This paper discusses a comparative study between ISO 900:2000 standards and two groups of total quality management approaches, one proposed by different intelligents such as, Crosby, Deming, etc. and the other by two widely used quality awards namely EFQM and MBNQA. Based on this study seven criteria and their subـcriteria were identified which determines the differences and communalities between ISO 9000:2000 standards and also indicate that these standards comply with a total quality approach. Based on the comparative analysis conducted, two similar instruments in questionnaire with alike content were developed to measure the level of implemention of TQM in the organizations implementing TQM and to collect the views of quality experts respectively. Through statistical tests, reliability and validity including construct validity of the mentioned above instruments were approved by factor analysis. Finally by analyzing the data collected from the two instruments a gap analysis aimed at identifying the differences between what is really done in the organizations and what quality experts believe that should be done was performed. The results of this research can help the organizations of the country in their efforts on implementing TQM.

Tehran province experienced one of the severest drought status during 1998 to 2000. This drought can be assessed by drought indices. Drought indices are quantitative expression of this disaster that make its spatial and temporal evaluations possible. In this research work three indices including EDI, SPI and DI have been used to develop monthly drought maps for the aforementioned period, using the information of 43 meteorological stations and geographical information system (GIS). The results show that DI has very exaggerated responses to rainfall, especially to the summer rainfall. Also SPI is not responsive enough to rainfall deficiencies. Morover, it frequently detected normal situation for this period. But, EDI is able to response properly and shows good temporal and spatial consistency in drought detection.

Aims: University students have increased health problems, mental disorders, and health risk behaviors, compared to the general population. Health consequences may increase by the presence of multiple risk factors and the lack of protective ones. This research aimed to study the health-related quality of life of students, and its relation to academic stress coping and happiness-increasing strategies.
Instrument & Methods: We used a relational transversal design, with a random stratified polytypic sample of 351 students. Applied instruments include the academic stress coping scale, the positive affect enhancing strategies scale, and the EUROQoL 5-D. The analysis included descriptive statistics, student t, simple ANOVA, and profile analysis through the hierarchical cluster method. Analysis was made with JAMOVI 1.6 software
Findings: Sixty-five percent of students reported having one or more health problems, mostly mental health type and the health-related life quality perception score was 75 (from 0-100). We found five stress-coping profiles: intellectual, support-seeking, active, optimist, and passive, which differentiated in health-related life quality (F_(4,343)=16.095, p<0.01).
Conclusion: University students have a lower health-related quality of life than the general population. Academic stress-coping and happiness-enhancing strategies showed 5 profiles.

Aims: Our study aimed to find the association between general and central obesity with peers influence, home food environment, and out-of-home food environment in Iran.
Material & Methods: This cross-sectional study was performed on 15- to 18-year-old students in Yasuj, Iran selected using a stratified random sampling method. A demographic questionnaire was used and a 37-item questionnaire was used to assess the information about the peers' influence, home food environment, and out-of-home food environment. Weight, height, and waist circumference were measured for all participants. Body mass index and waist-to-height ratio were calculated.
Findings: Information from 241 participants including 120 girls and 121 boys were included in the analysis. The mean age of the participants was 16.43±0.88. None of the variables of peers influence, home food environment, and out-of-home food environment showed a significant association with anthropometric indices.
Conclusion: In our study, none of the peers' influence, home food environment and out of home food environment, could justify the participants' obesity. It seems that studies with larger sample sizes and more demographic diversity are needed.

 Take-all is a devastating soil-borne disease of wheat Triticum aestivum L. The disease is caused by the pathogenic fungus Gaeumannomyces tritici, a pathogen distributed worldwide in major wheat production areas that causes severe damage to wheat production. Identification of genotypes with the high nutritional value of seeds can be considered in controlling this disease and in wheat breeding programs. Variation of high molecular weight glutenin subunits (HMW-GS) at the Glu-A1, Glu-B1, and Glu-D1 loci was studied using SDS-PAGE electrophoresis in 15 genotypes of bread wheat. A positive correlation was found between 1000-seed weight and the 5 + 10 allele (r = 0.594), indicating that presence of this allele will increase 1000-seed weight. A simple corresponding analysis was conducted to show the relationship between the take-all index and the genetic diversity of genotypes and the association between the bilateral groupings of individuals based on two criteria (genetic diversity and disease response). The result of stepwise regression showed that glutenin subunit null, 7 + 8, 2*, 7 + 9, 5 + 10 have linkage with resistance to take-all disease. Findings are useful in breeding programs to improve baking quality, develop uniformity and improve heterogeneous genotypes by selecting the best genotypes.

Persian poetry in the 2000s, like many literary and artistic texts, has hidden meaning and reason the enjoyment of discovery of which is met by the criticism process method. One of the methods of studying poems of this decade is to look at the mutual contradictions, which indicate some parts of meaning, because if a poet accepts the historical evaluation of contradictions, he shows his alignment with classic beliefs and if he criticizes it, he represents the intellectual and cultural changes in personal or social level. In analysis of text contradictions, one of the items to be studied is the type of relation that the author or poet connects between two sides of contradiction, and in this case, poets in the 2000s indicated many intellectual infrastructures and type of evaluations changed to them. Among 20 poets studied in this research, 7 poets (Sare Dastaran, Majid Rafati, Garous Abdolmalekian, Abbas Saffari, Sara Mohammadi Ardehali, Shahab Mogharrabin, and Hafez Mousavi) obviously introduced invalid the goodness and badness of two sides of contradiction; i.e. the positive and negative aspects or vice and virtue of parties to the contradiction. The research findings show that the poets in the 2000s make doubt on the known and general contradictions, and also include in their works the new visual fields suitable to the language and time for invalidating the vice and virtue aspects of contradictions

1. Introduction
One method of poetry study in the 2000s is the analysis of double contrasts, and originates its theoretical fundamentals from structural linguistics. Poetry criticism with this structurali view can connect to the different approaches; such as discourse analysis approach, sociological criticism, moral criticism, etc. For example, ideology governing the poetry of this period, which in fact reflects the thinking method of a special class in society, can be recognized and its formalities can be analyzed with power by discourse analysis view. Historically, the word of double contrasts was used first by Nikolai Trvbstskvy (1890-1938) but legally and formally appeared in theories of structural linguist, Ferdinan de Saussre (1857-1913) and specifically discussed in Public Linguistics (1915). Summary of Saussre's discussion is that all human behaviors are systematic, and for this purpose, the rules governing it shall be achieved to understand the language arisen from the mind and thinking function. One of such fundamental rules is the contrasts. Understanding the double contrasts indicate some parts of meaning in literary text.
 
2. Research Questins
The main problem of this research is: what predominant view and thinking does reflect the analysis of double contrasts in poetry of the 2000s? and what value system is indicated by the most important social and cultural criticism of poets of this period? The most significant research hypothesis is that the double contrasts in poetry of this decade indicate the diversity of beliefs and values to the previous periods, and poets of this decade reflect a type of invalidity of values by choosing or creating the contrasts and also through a relationship connected among them, deemed the values invalidity criticism. In other words, a poet of the 2000s doesn't distinguish a border between good and bad, and this one-sidedness can be his/her indirect and poetic criticism to decline of the values system in the community.
3. Research method
The research method in extraction and analysis of contrasts is that: 1- a list of text contrary couples has been extracted; 2- the contrasts based on the positive and negative poles are classified under the more common contrast; 3- ideological foundation of text has been clarified by analysis of value contrast of two poles and achievement of predominance of one party of contrasts; 4- general and fixed beliefs transferred to the audience by text are indicated by this way. Not based on the literary credit chosen based on the multidimensionality of specifications such as age and sexual learning, public and private publication, etc, regarding the presence of the past and young generations, presence of two groups of men and women, existence of two contrast ideologies (opposing and agreeing the formal discourse), presence in meetings and receiving the literary awards or quitting this movement, and relationship with public and private publisher, poets and books on study have caused the research result is an average of all intellectual and literary movements.
 
4. Literature Review
A list of more than 20 papers can be collected in the research background, each has analyzed a text based on the double contrasts and reached some perceptions of structure and meaning; but a collection of texts reflecting a view in a definite period with its contrasts has not been paid attention by the Persian language and literature researchers.
 
5. Results
The analysis of companion contrasts in Persian poetry in the 2000s indicates the poets connect a relationship between the doubles which are different to the literary traditions and classic views because there is not any direction to the value side, accepted by the public, compared to the anti-value and value sides. This adversity of classic formalities is indicated in different forms. For example, the poet sometimes knows there is no difference between positive and negative sides and their achievement is the same; sometimes believes to accept the contrary nature of doubles, so, doesn't try to solve them; sometimes negative side accepts the contrary bitterly; etc. Totally it can be said that the double contrasts in poetry of the 2000s reflect a kind of transition from traditional thinking, and is a kind of criticism to instability of value system in the minds. Based on the findings of this research, there are some contrast relationships among the companion doubles in poetry of the 2000s in the following 6 classes which are as follows according to their role: 1- removing the contrast (mostly focusing on the hidden negative side), 2- keeping the contrast (by focusing on the negative side), 3- beauty-creation by contrasts (imagination- language orientation), 4- alignment with the classic contrasts (mostly in scope of lovings), 5- creation of new contrasts or presentation of the various interpretation of the common contrasts, and 6- expression of the doubt and uncertainty to the nature of contrasts.

Drought is one of the most important abiotic stresses affecting plant growth and development. In the present study, the changes in lipid peroxidation rate and antioxidant enzyme activities were determined at different concentrations of PolyEthylene Glycol (PEG) 6000 (0, 5, 10, and 15% (w/v)) for two canola cultivars (SLM046 and Hyola 308). In order to produce water deficit, 12 days old canola seedlings were treated with PEG 6,000 in half strength Hoagland solution for 24 hours. PEG treatments increased the content of Malondialdehyde (MDA), a product of lipid peroxidation, in roots and shoots of both cultivars; but for Hyola 308 cultivar, the rate of increase of MDA was higher than SLM046 cultivar. In addition, drought did not have any significant effect on MDA content in roots of SLM046 cultivar. On the other hand, water stress increased Superoxide dismutase (SOD), Peroxidase (POD), Catalase (CAT) and Ascorbate peroxidase (APX) antioxidant enzyme activities of both shoots and roots of the studied cultivars; but activity of these antioxidants in SLM046 cultivar was obviously higher than in Hyola 308 cultivar. These results showed a higher water stress tolerance for SLM046 cultivar.

In this paper, the residual stresses due to circumferential arc weld of the thin walled cylinders have been investigated by using finite element method. The cylinders were of aluminum alloy series 5000. The 3D finite element models have been developed in ABAQUS. The thermal-mechanical analysis was considered as uncoupled. The thermal and mechanical material properties have been defined as temperature dependent. The residual stresses were measured by using Hole drilling method. The experimentally measured data have been used to verify the result of finite element model. By using Taguchi method, the effect of eight geometrical, technological and material different factors have been investigated on the maximum residual stresses in the axial and hoop directions. Considering to a number of factors, L12 Taguchi array has been selected. Each factor has been studied in two levels. The result of statistical analyses have shown that increasing the outer diameter, thickness, heat input rate and yield strength in the studied levels caused the axial and hoop maximum residual stresses enhanced. However, the increase of the section number and the interaction between the outer diameter and heat input rate have led to decrease the maximum hoop residual stresses. Also, the yield strength of material was the most effective factor on maximum axial and hoop residual stresses.

In recent years, measurement of residual stress by ultrasonic method is developing because of nondestructive nature, portable equipment and being cheap and fast. In this research, the Capability of ultrasonic method by using longitudinal critically refracted or Lcr wave in measurement of longitudinal welding residual stress has been scrutinized. For this purpose, two plates of aluminum alloy series 5000 were joined by TIG welding method. Measurement of longitudinal residual stress by ultrasonic method was done in closeness of surface via 5 MHz transducers based on acoustoelasticity theory. In order to create Lcr wave and transmit it into specimen, an ultrasonic wedge was made based on Snell’s law. Also a triaxial table was used to control the wedge movement and keep the pressure on it fixed. In order to calculate residual stress and increase in accuracy, acoustoelastic constant for each three welding zones, including weld metal, HAZ and base metal was obtained separately from uniaxle tension test. In order to validate ultrasonic method results, measured longitudinal residual stress by x-ray diffraction method in 5 points on the specimen surface was used. Finally after comparing the results of two used methods with each other, good agreement was seen which indicates the good ability of ultrasonic method in measurement of longitudinal residual stress.

Heeled concrete walls (T-Wall) are used for privacy, protection and some form of blockage. These walls can be built precast or cast in place and can be designed according to the possible loads such as blast loads, earthquakes, winds and so on. Also, the use of fiber concrete to absorb more energy and durability can be a good solution in the construction of such walls. Resistance, stability, and possibility of overturning of these walls due to the blast load and depth of buried walls are those that should be controlled by the designer. In addition to all the controls mentioned, one of the important issues is to optimize the cost of construction and consumables, so comparing reinforced concrete use with fiber reinforced concrete is of interest. In this study, six types of walls are considered: Type 1 and 2 walls with 3 m height and 2.5 m width, Type 3 and 4 walls with 4 m height and 2 m width and Type 5 and 6 walls with 5 m height and are 1.6 meters wide. Which, the walls of Type 5 and 6 are non-prismatic and are one meter buried in soil. In addition, type 1, 3 and 5 walls are made of fiber reinforced concrete and type 2, 4 and 6 walls are reinforced concrete. The purpose of this study is to investigate the resistance of concrete prefabricated walls against the impact and explosion. During an explosion, there is an explosive wave that spreads from the center of the explosion. Waves spreading at a later time are much faster than the speed of the initial waves. When a structure is exposed to the wave front, its surface pressure rises and reaches its maximum value in a very short time. This pressure affects the structure on all sides rapidly. This wave is a combination of high-pressure shock that emits outward from the center of the explosion and decreases as a function of the time and place of the explosion. The energy released by the explosion affects the structure in two ways. The first effect is the blast pressure, which is the key factor in determining the structural response, and the second effect is the dynamic pressure or the secondary pressure, which at high speed results in the debris being thrown around. Therefore, the most important parameter of an explosion is the forward blast pressure, the amount of which depends on the type of explosive and the weight of explosion. Hence, in order to find the above parameters, the 6 types of discussed wall modeled in Abacus software by CDP method. Also, the earthquake loading with different acceleration is applied to the walls and lateral displacements of them are calculated by using linear time history analysis with SAP2000 software. Finally, the performance level of walls under loads has been evaluated according to the national building earthquake loading criteria and 21th national building regulations. The results of the present study show that; the use of fibers has a positive effect on improving the performance level of prefabricated walls against dynamic loads such as explosion and earthquake.
