Briefly explain the role of CH3CO2Na in the preparation of Fe(C5H7O2)3. Describe the metallurgy of iron. Which of the following compound has a specific rotation (a)D^25 = 0? Give a full explanation of hybridization. Explain the term lattice type in detail. ...
Explain the term "phospholipid" as used in biology. Describe the amphiphilic nature of phospholipids and how this facilitates the structure of the plasma membrane. How proteins can be associated or incorporated into the structure of a lipid bilay...

Both cases, true and quasi anti-repeaters, are manifested in highly anti-correlated seismic waveforms. The literature on such phenomena is still limited. The term ‘anti-repeater’ has been first used, to our knowledge, for describing such observations at the Bucaramanga nest, Colombia23,24, whe...
A recent study showed surprising features of reversed-polarity of TRBV TCRs such that interactions of NP366:H-2DbD227K to TCRs B13.C1 and B17.C1 induced T-cell signaling, whereas interactions of the same pMHC to B17.R1 and B17.R2 TCRs did not13. Despite that the former two TCRs ...
Influence of Decreasing Solvent Polarity (1,4‐Dioxane/Water Mixtures) on the Acid–Base and Copper(II)‐Binding Properties of Guanosine 5′‐Diphosphate The acidity constants of twofold protonated guanosine 5鈥 -diphosphate, H 2 (GDP) , and the stability constants of the [Cu(H;GDP)] and [...
Long-term MD trajectories allow us to assess the water permeability of the model membranes (see Computational Methods). Figure 5 shows the frequency of water permeation events (due to free diffusion) across the five model bolalipid membranes, and also across two ''common'' phospholipid bilayers ...
However due to limitations in the existing methods to assign senses to words in open-domain texts, this word sense based approach has not demonstrated significant advantages over the traditional term-based approaches. Also most sentiment lexicons consider limited polarity values (usually 2 or 3), ...
Water is a polar molecule consisting of two hydrogen atoms and one oxygen atom. Although its net charge is zero, the molecule has a positive side (hydrogen) and a negative side (oxygen). This polarity causes the molecule to orient in a particular direction when in the presence of an electr...
Explain what is meant by the term "hybridization" in molecular orbital theory and show how the concept can be used to explain the structure and bonding in ethane C2H6, ethene C2H4, and ethyne C2H2. Use valence bond theory to describe which atomic orbitals overlap...
