Abstract: 

In order to identify the correlations and relationships between different traits in the bread wheat, 30 genotypes were investigated as sub-factors under the split plot experiment in the completely randomized design in greenhouse and the randomized complete block design in the field with three replications under the normal irrigation and post-anthesis water stress conditions. The results of the canonical correlation analysis showed that at both normal and moisture stress levels, there was a significant correlation between the pair of canonical variables obtained from the phenological traits and the yield components. Under the normal conditions in the greenhouse, to increase the spike density and length, the number of days to 50% flowering can be considered as a suitable selection criterion. According to the results of canonical correlation analysis, under the stressed conditions in greenhouse, to increase the spike length, the number of days to the heading, maturity and 50% of flowering were among the important and effective factors. Under the optimum irrigation conditions in the field, the number of days to maturity was considered as one of the factors influencing the seed weight per spike. The results of canonical correlation analysis under the field stress conditions showed that to increase the 1000-seed weight, the number of days to maturity can be considered an appropriate selection criterion.

Abstract: 

این مقاله روش جدیدی را برای ایجاد جمعیت اولیه در الگوریتمهای ژنتیکی به نام  Noisy Normalمعرفی می کند. در این روش، برخلاف روش Quasi random، علاوه بر اینکه از تمام نقاط دامنه (در هر بعد) نماینده ای وجود دارد، نقاط انتخابی در اجراهای متفاوت تغییر نیز می کنند. با توجه به توزیع مناسب این نقاط، احتمال اینکه الگوریتم برای تعداد جمعیت کم در تله های احتمالی بیفتد، پایین می آید. روش ارایه شده مشکل توزیع نامناسب Pseudo random و همچنین مشکل عدم تصادفی بودن جمعیت اولیه و توزیع نامناسب برای توابع با ابعاد بالا در روش Quasi random را نیز اصلاح می نماید و منجر به پاسخ مطمئن تری می شود. نتایج آماری بدست آمده این مطالب را تایید می کنند.

Abstract: 

In process of sucrose determination in sugar beet, pulp analysis by polarometric method is done on the basis of fresh root weight. The volume of the juice of 26 grams of the pulp is considered 23 ml that with 177 ml of clarifying agent would be 200 ml. Drought stress and dehydrated root reduce. The volume of the pulp extract of 23 ml. The objective of this experiment was to determine the proper method for juice extraction from beet roots grown under drought, salinity and normal conditions in the procedure of sugar content measurement. Sugar beet roots produced under various conditions were subjected to dehydration after harvest. Three levels of dehydration [(A) including fresh beet with 76±1 percent moisture (a1), dehydrated roots up to 70± 1 (a2) and 63± 1 (a3) percent water content] and three juice extraction methods [(traditional cold digestion (b1), hot digestion (b2) and improved French method (b3)] were arranged in a factorial experiment (3*3) in CRD with 12 replications. Sugar content, dry matter, marc, brix and juice electrical conductivity were determined for all treatments. The results showed that beet dehydration from 76 to 68 percent increased both dry matter and marc contents from 24 to 32 and from 4.7 to 7.1 percent, respectively. In normal roots there was no significant difference in terms of sugar content determination by various extraction methods. However, sugar content of beet roots grown under semi-salinity (P<0.05), salinity and drought (P<0.01) conditions were affected significantly by extraction methods. These differences are presumably due to differences in marc and dry matter contents. In conclusion, overall there was no difference between the hot digestion and French methods in all conditions. Whereas, the difference of traditional methods with French method for dry matter of 24 to 27 percent was not significant. Thus, it is recommended to determine sugar content of beet roots having up to 27 percent dry matter by cold digestion method and in the beet roots of greater than 27 percent dry matter the proper way of juice extraction is French method.

Abstract: 

Purpose: According to Sutherland's definition, white-collar crime is a crime that is committed by "respected and high-ranking" people. Studies clearly show that women are under-represented in official statistics related to certain types of organizational white-collar crime. Despite this, what exactly causes such a pattern is worthy of reflection and interpretation. This article aims to analyze the role of gender in committing white collar crimes in Iran and Norway. Method: The research method used in this article is a mixed (combined) exploratory research method with meta-composite and Delphi approaches. Library method was used to collect data. The study population of the research includes all the articles related to the research topic. In order to carry out the research, after designing the research questions, a systematic search was conducted based on relevant keywords from the Google scholar, Scopus, SID, IRANDOC, etc. databases between 1390 and early 1402. Findings: The findings show that the number of initially extracted codes were 538 codes, which were converted into 241 codes in the next stage and 38 sub-codes in the secondary (central) coding stage, which were converted into 6 codes in the selective coding stage. became the main Conclusion: The results of this research indicate that 6 main categories or themes were extracted for white collar crimes, which are: 1. individual dimension with twelve components; 2. social dimension with four components; 3. economic dimension with two components; 4. organizational dimension with eight components; 5. Political dimension with three components and 6. Laws and regulations dimension with three components

Abstract: 

We study the transport of electrons in a graphene NSN structure in which two normal regions are connected by a superconducting strip of thickness d. Within Dirac-Bogoliubov-de Gennes equations we describe the transmission through the contact in terms of different scattering processes consisting of quasiparticle cotunneling, local and crossed Andreev reflections. Compared to a fully normal structure we show that the angular dependence of the transmission probability is significantly modified by the presence of superconducting correlations. This modifation can be explained in terms of the interplay between Andreev reflection and Klein tunneling of chiral quasiparticles. We further analyze the energy dependence of the resulting differential conductance of the structure. The subgap differential conductance shows features of Andreev reflection and cotunelling processes, which tends to the values of an NS structure for large ds. Above the gap, the differential conductance shows an oscillatory behavior with energy even at very large ds.

Abstract: 

Immunophenotyping of lymphocytes is very essential for evaluation of immune system.Due to the effect of environmental factors and ethnical diversity on immune system, establishment of an internal normal range of lymphocyte subsets is a necessity for each population. The aim of this study was to determine the normal range of T and B lymphocytes, and NK cells in normal Iranian adults.Two hundred and thirty three Iranian normal adult volunteers took part in this study.Complete Blood Count (CBC) was performed for them with Sysmex (KX21) and cells with CD3, CD4, CD8, CD19 and CD16/56 surface markers were simultaneously detected by flow cytometry method with FACstar system. Their percentile and absolute count were determined.The volunteers were 150 male and 83 female. Mean percentages of lymphocyte subpopulation were: CD3 (67.66±7.76), CD19 (14.41±5.09), CD4 (39.22±6.7), CD8 (25.42±5.4) and CD16/56 (10.14±6.42).Also, their mean absolute count of lymphocyte bearing CD3, CD19, CD4 and CD8 were 1, 504±505/6l, 332±186/6l, 827±313/6l and 522±185/6l, respectively.Our results are comparable with similar Asian results from other Asian population, but are different from European population, we therefore conclude that it is necessary for each laboratory to establish an internal normal range for the lymphocytes bearing abovementioned markers.
