• The properties of unbleached CNMs are highly dependent on the pulping process. Range lignin structures can create tailored lignin/CNM composites. Water-dispersible CLPs allow for homogeneous blending with CNMs. Combinations and enable new functionalities applications. With increasing demand greener alternatives to fossil-derived products, research cellulose nanomaterials (CNMs) has rapidly ex...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...

This paper aims at designing and validating a model for integrating the ethical components with technical competencies in curriculum based on competency in industrial mechanics’ branch. Method: The research approach is based ...
Concurrent Engineering is the latest buzzterm for bringing products to market faster. This paper explores how a distributed computing environment can enable concurrent engineering. The following topics are covered: • Definition of concurrent engineering and how it applies to non-technical as well as technical companies. • Case studies of companies who have harnessed their distributed computing ...
Concurrent Design (CD) is a systematic approach to integrated product design that emphasizes the response to customer expectations and the combination of creativity and engineering. Such a concept represents also the basis of ProductService System (PSS), which represents a valid way for companies to add value to their products, create new value propositions, and easily improve their solution po...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Post disaster temporary housing is one of the challenges of disaster preparedness in any country; because there is a basic need for sustainable, affordable and efficient temporary housing. This study aimed to evaluate the scientific products in post-disaster temporary housing, focusing on the field of architecture and using scientometric methods and content analysis, systematic review and co-o...
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
quality of products and services is considered as a key factor for customer satisfaction. quality function deployment (qfd) is known as a critical tool for translating voice of customers to prioritize technical requirements of a production. the level of this satisfaction depends on the number of fulfilled requirements. it should be noted that this level varies according to the possible constrai...
