The classical Bohr inequality says that |a+b|2 £ p½a½2+q½b½2 FOR all scalars a, b AND p, q > 0 with 1/p + 1/q = 1. The equality holds if AND only if (p-1)a = b. Several authors discussed operator version of Bohr inequality. In this paper, we give a unified proof to operator generalizations of Bohr inequality. One viewpoint of ours is a matrix inequality, AND the other is a generalized PARALLELOGRAM LAW FOR ABSOLUTE VALUE of OPERATORS, i.e., FOR OPERATORS A AND B on a Hilbert space AND t¹0, ½A-B½2+ 1/t½T A+B½2= (1+t) A½2 +(1+1/t) B½2.

Purpose: Managers are one of the important elements of an organization, FOR this reason, in order to draw the future of the organization, it is necessary FOR the planners to specify the conditions of their selection AND appointment. ThereFORe, the current research has been done with the aim of identifying AND analyzing the components of selecting future principals.Method: In this research, comparative AND benchmarking method is used as a prospective approach. This approach is based on the belief that today's advanced organizations/countries can be considered as a model FOR the future of another organization/countries in their respective subjects. FOR this, first, the fields of comparison AND benchmarking were determined using Brody's four-step comparison method; then the countries of Canada, FinlAND, Australia, South Africa, AND Japan were selected according to the qualitative balance VALUE in the international advanced TEAMS test, human development index, life quality index(health, instruction, AND welfare), education quality index, AND other scientific-scholarly indexes; finally, by extracting the criteria FOR the selection AND appointment of principals through content analysis AND comparison with Iran, the proposed framework FOR Iran has been presented.Findings: A total of 61 components FOR the selection of secondary school principals were identified from among the studies conducted in the selected countries in this article. By extracting the commonalities AND differences of each of the components among the countries, it was found that the highest index of manager selection AND appointment belongs to Japan AND the lowest one is related to FinlAND.Conclusion: There are similarities between the components of selection of principals of secondary schools in Iran AND selected countries. In Iran, special attention should be paid to important components such as adherence to religious principles, appropriate personality traits, creativity AND innovation, motivation to develop capabilities, professional growth, power of supervision AND accountability, social image, leader skills, AND purposefulness AND FOResight.

Intracytoplasmic sperm injection (ICSI) is one of the most successful techniques of Assisted Reproductive Technology (ART) AND is mostly in use FOR the treatment of infertility with male factors. In this method, beFORe injecting sperm into the intracytoplasmic of the oocyte, cumulus cells around the oocyte must be stripped to facilitate the injection process. To achieve this, both enzymatic AND mechanical methods are used in embryological laboratories FOR denudation, which has major deficiencies, including the possibility of damaging the oocyte prior to the injection process. In this research, a microfluidic-based device is introduced FOR the separation of cumulus cells around the oocyte with minimum manual operations. The results prove high efficiency, AND non-destructive denudation of the oocyte with the reduced amount of culture medium leads to the low-cost preparation process of oocytes. The process can also be integrated with ICSI chips under development AND will be reported shortly.

The communities of the Kura- Araxes cultural complex with their highly distinctive cultural AND economic features represent the occupation of some parts of the Near East AND Caucasia during the Bronze Age.  Generally, the origin of this culture is sought in the Southern Caucasus. In Iran, the spread of this cultural tradition represents not only a rupture in the cultural development of the Mesopotamian traditions. Environmental changes linked to Rapid Climate Change (RCC) also FORced the population to develop new economic strategies. Until about two decades ago, knowledge of the flourishing Kura Araxes occupation was limited to the north-west of the country AND to some parts of the Central Zagros, but recent research in the zones south AND north of the Alborz Mountain Range, on the northern edge of the Central Plateau allows by now to present a more detailed picture of the Kura Araxes occupation in both diachronic AND synchronic perspective. Recent archaeological excavations in the two sites of Qaleh Tepe AND Ali Yourd Tepe revealed some important new data from Kura-Araxes settlements in the corridor of the north Central Plateau AND northwestern Iran. The two sites are located in the eastern Zanjan Province in the Abhar Rood Basin. This paper aims to update the chronology of the Kura-Araxes culture based on the radiocarbon dates from the two sites of Qaleh Tepe AND Ali Yourd Tepe. The stratigraphy AND radiocarbon dates of the two sites reveal the beginning of the Kura-Araxes culture in the region from c. 2900 BCE, followed by a quick extension into the northern Central Plateau, where it is represented by sites such as Shizar, Doranabad, Ostur, AND Barlekin. Similarity AND diversity characterize the Kura-Araxes cultural complex.  However, based on the current data, the ceramic style represents a common feature, but also the architectural remains indicate a common cultural tradition during the first quarter of the third millennium BCE in the Central Zagros, northwestern Iran, AND on the Central Plateau

This paper presents characterizations of M-fuzzifying matroids by means of two kinds of fuzzy OPERATORS, called M-fuzzifying derived OPERATORS AND m-fuzzifying difference derived OPERATORS.

Excavations in Tepe Barveh were conducted with the aim to shed further light on the period of painted Bronze Age wares AND to refine the existing chronology FOR the Lesser Zab Basin in the first half of the 3rd millennium BC. Thanks to its location in the upper valley of the Lesser Zab, the Barveh region served as a natural pathway FOR interaction between the Zagros foothills zones with the Rania AND Peshdar Plain in Sulaimaniyah province in Iraqi Kurdistan, AND the southern basin of Lake Urmia. By its overlapping Bronze Age sequence, the site offers a strong potential to fill the existing gap of inFORmation FOR the Early Bronze Age occupation in northwestern Iran. A FORemost purpose of this paper is to situate Barveh within northwestern Iran, AND to explore intra- AND inter-regional interactions. The stratified occurrence of Painted Orange Ware (POW) is helpful to establish a sequence FOR the region AND to fill the existing lacuna. EBA sites in northwestern Iran beyond the Kura Araxes zone remain understudied, AND few sites offer deposits of considerable depth. The Early Bronze Age is generally associated with the burnished black pottery, while the orange pottery, a coeval AND equally important cultural hallmark, has attracted less attention AND remains a little known tradition. Hence, in light of the material culture excavated at Barveh, this paper seeks to gain an insight into the ways in which Tepe Barveh interacted with other regions dominated by the orange pottery culture. The ca. 8-meter deep EBA deposit at Barveh built up over c. 300 years AND represents this period of POW in an uninterrupted sequence, attesting to cultural continuity over an extended period of time. The culture shows parallels with EBA sites in the southern Urmia Lake Basin AND in the Rania AND Peshdar plains in Iraqi Kurdistan
