tabriz petrochemical complex is located in northwest of iran and west of tabriz oil refinery and mostly produces raw plastics. in this study the implementation of reduction of hazardous waste contact in this complex with special emphasis on personal protective equipment (ppe) is discussed. accordingly different hazards threatening personnel, indoor and outdoor environment were determined. in or...

Cryptographic standards serve two important goals: making different implementations interoperable and avoiding various known pitfalls in commonly used schemes. This chapter discusses Public-Key Cryptography Standards (PKCS) which have significant impact on the use of public key cryptography in practice. PKCS standards are a set of standards, called PKCS #1 through #15. These standards cover RSA...

BACKGROUND Clinical perfectionism is a transdiagnostic process that has been found to maintain eating disorders, anxiety disorders and depression. Cognitive behavioural models explaining the maintenance of clinical perfectionism emphasize the contribution of dichotomous thinking and resetting standards higher following both success and failure in meeting their goals. There has been a paucity of...

Using Precise Point Positioning (PPP) we show the potential for comparing frequency standards with time stabilities of under 300 ps in flicker phase noise for time periods of 1 to 10 d. This leads to comparisons at 1 part in 10 or better at 10 d. We compare short baseline PPP results with 2 hour data from the NIST Measurements System. We compare results from the NIST – USNO baseline with hourly...

Study of Band Broadening occurring in Size Exclusion Chromatography (SEC) is reported using very narrow PS standards obtained and characterised by Temperature Gradient Interaction Chromatography (TGIC). Chromatograms are fitted by Exponentially Modified Gaussian functions (EMG) and mapping of band broadening is obtained for different column sets. Interpretation of the skewing of the chromatogra...

College students (60 female, 33 male) were asked to describe their personal standards for romantic relationships and what types of information were important for their creation. Respondents' open-ended responses revealed an average of over six standards, the content of which closely matched a comprehensive framework of relationship standards (Vangelisti & Daly, 1997). Open-ended descriptions re...

Abstract This article proposes to consider the education system as a factor in formation of people’s personal values. We examine students’ perceptions degree which existing educational standards are oriented towards and development values, well formulate proposals for implementation systems approach improving complex The methodology applied included: desk analysis by comparison, deduction, indu...
