The Codex Alimentarius Commission (CAC) was established in 1962 as a joint venture between FAO and WHO

Definition PEM is manifested primarily by inadequate dietary intakes of protein and energy. PEM is almost always accompanied by deficiencies of other nutrient. PEM can be divided as primary PEM and secondary PEM

一、是一种少年儿童常见的结缔组织病 One of the most common connective tissue diseases of children 二、以慢性关节炎(滑膜炎)为主要特点 Characterized by chronic arthritis (synovitis of the joints) 三、多脏器受累,如肝脾肿大、淋巴结肿大、浆膜炎(心包积液)等 Visceral involvement ,such as hepatosplenomegaly, lym- phadenopathy and serositis (pericardial effusion)

5. Food Handling Practices 5.1 Use of colour coded equipment 5.1.1 Equipment used in different areas of a factory should be colour coded or clearly dentified in such a manner as to designate that department and to prevent the risk of cross contamination e.g. chopping

Applications of Inverters Conversion of electric power from DC type energy sources to AC type load -Battery Photovoltaic cell (Solar cell) Fuel cell +As a part of composite converter AC-DC-AC frequency converter(for AC motor drive) AC-DC-AC constant-voltage constant-frequency converter(for uninterruptable power supplies)

Transcriptional Regulation in Bacteria Thanks to the relative ease of doing genetics with bacteria, transcriptional regulation in bacteria is better understood than that in other organisms and has served as a framework for understanding transcriptional regulation in eukaryotic organisms

Chapter 26 RNA Metabolism 1. How is RNA synthesized using DNA templates (transcription)? 2. How is newly synthesized primary RNA transcripts further processed to make functional RNA molecules? 3. How is RNA and DNA synthesized using RNa as template (reverse transcription); 4. What is the evolutionary implication of the structural and functional complexity of RNA molecules?

Chapter 5 Macromolecules and Molecular Genetics DNA Replication Complementary base pairing Semiconservative Template and primer From 5'-phosphate to the 3'-hydroxyl end DNA polymerase and ligase A short stretch of RNA serves as primer Primase: a specific RNA-polymerizing enzyme

Ribosomal RNAs as Evolutionary Chronometers Reasons: Ancient molecules Functionally constant Universally distributed Moderately well conserved in sequence across broad phylogenetic distances

Z-Transform The DTFT provides a frequency-domain representation of discrete-time signals and LTI discrete-time systems Because of the convergence condition, in many cases. the DTFT of a sequence may not exist As a result, it is not possible to make use of such frequency-domain characterization in these cases
