یکی از ناخالصی های همراه زغالسنگ، گوگرد است که به دو صورت آلی و معدنی وجود دارد. میزان گوگرد بیش از حد مجاز در کنسانتره زغال و انتقال آن به مرحله کک سازی، سبب تولید کک نامرغوب می شود. این کک در کوره های احیا مستقیم ذوب آهن، باعث تولید چدن و فولاد نامرغوب می شود. همچنین وجود گوگرد در زغالسنگ های حرارتی موجب تولید گاز so2 می شود که اثرات زیست محیطی نامطلوبی دارد. روش های متفاوت شیمیایی، فیزیکی و ...
DOI: This paper reviews the progress of systems biology applied to research on sustainable utilization of Chinese materia medica (CMM) resources in the following aspects: identification and evaluation of CMM resources, analysis of biosynthesis and their regulation of active ingredients in medicinal plants, metabolic engineering and synthetic biology research of medicinal plants, and molecular b...
Pancytopenia is a common haematological condition often encountered in day to day clinical practice. It is defined as a decrease in all the three cell lines of blood viz., red blood cells, leucocytes, and platelets. Many diseases affect production of these cells by bone marrow resulting into pancytopenia i.e., simultaneous presence of anaemia, leucopenia, and thrombocytopenia. Pancytopenia is d...
This paper describes an assessment of the Rational Unified Process (RUP) based on the Capability Maturity Model (CMM). For each key practice (KP) identified in each key process area (KPA) of CMM levels 2 and 3, the Rational Unified Process was assessed to determine whether it satisfied the KP or not. For each KPA, the percentage of the key practices supported was calculated, and the results wer...
The Capability Maturity Model (CMM) has obtained world-wide status as a premier process improvement framework. This influence has not gone unnoticed by the academic community who has utilized the CMM as a key construct representing a firm’s IT project management and development capabilities. However, an examination of the current state of research reveals no consensus on how to best operational...
Clavibacter michiganensis subsp. michiganensis (Cmm) is a Gram-positive seed-transmitted bacterial phytopathogen responsible for substantial economic losses by adversely affecting tomato production worldwide. A high-throughput, cell-based screen was adapted to identify novel small molecule growth inhibitors to serve as leads for future bactericide development. A library of 4,182 compounds known...
OBJECTIVE To assess the use of cervical mucus monitoring (CMM) in women trying to conceive and determine whether monitoring is associated with increased cycle-specific probability of conception (fecundability). DESIGN Time-to-pregnancy cohort study. SETTING Population-based cohort. PATIENT(S) Three hundred thirty-one women trying to conceive, ages 30 to 44 years, without known infertility...
CMM has been well accepted by the world as the standard for software development process control, quality improvement, and software company capacity evaluation. Aiming at the software outsourcing service market, more and more Chinese software companies are involved in the CMM certifications rush. However, to most of them, CMM is a very challenging goal. As China’s software industry is still at ...
This paper describes a calibrated and an uncalibrated method for integrating a vision system with touch sensors and a Coordinate Measuring Machine (CMM). Traditionally, vision systems are used to measure machined parts and to localize manufacturing defects based on appearances. Our system relies on a “coarse-fine” approach to integrating vision with CMMs. Vision guides the CMM to the feature to...
طزره بخشی از دامنه جنوبی البرز را تشکیل می دهد که در فاصله 80 کیلومتری غرب شاهرود و40 کیلومتری شمال دامغان قرار گرفته است و منطقه کلاریز نیز در سمت غربی معدن طزره قرار دارد. این معادن در مسیر خود چندین گسل فعال را قطع می کند که خود نشان از پتانسیل بالای لرزه خیزی در منطقه می باشد. بدون شک رویداد زمین لرزه های نیرومند ناپایداری های دامنه ای را در محدوده معدن به همراه خواهد داشت. طی 40 سال گذشته ...
