Madhumati Rao, C. Venkata Rao,
Abstract Phase equilibrium data are presented for the ternary liquid systems, namely, acetic acid‐water‐hexane, ethylene glycol‐water‐ n ‐butanol, ethylene glycol‐water‐ethyl methyl ketone, and ethyl methyl ketone‐water‐ cyclo hexane. The tie‐line data for all the systems have been analysed by the methods of correlation of Othmer & Tobias and Hand, and fitted reasonably with the respective plots. For the system acetic acid‐water‐hexane, the tie‐lines, when produced beyond the binodal curve, meet at ...

Ternary liquid equilibrium data at 30°C are presented for the systems containing water and methyl isobutyl carbinol with formic, acetic, propionic and butyric acids respectively as solutes. The tie-line data have been correlated by the method of Hand. Formic acid is found to favour the aqueous layer, whereas propionic and butyric acids are observed to prefer the solvent layer. With acetic acid, however, the phenomenon of solutropy is observed at about 10 per cent acid composition, although the distribution ...

Abstract Constant pressure diffusion rates of hydrogen through Vycor porous glass were measured in nitrogen and neon systems. The experimental diffusivities are less than those predicted by the random pore model indicating that this model may not be satisfactory for a low porosity material such as Vycor. Interpreted in terms of an assembly of parallel pores the data suggest a tortuosity factor of approximately 2.4. Rate data for the ortho‐para hydrogen reaction were also measured at −196°C. and 1 ...

Early decompression in Pott's paraplegia gives encouraging results. It produces speedy recovery from paraplegia and ensures rapid healing of the lesion. Lateral extrapleural decompression without fusion for lesions of thoracic vertebrae is safe and satisfactory. It gives adequate exposure of the anterior and posterior parts of the vertebral bodies and of the theca, without endangering the stability of the spine. Age, sex and site of the lesion have no influence on the prognosis, whereas paraplegia ...

One of the main reasons for employing coils to heat and cool liquids in tanks is its low purchase cost. The technique is used in a great variety of industrial processes such as: the production of paint, food additives, pharmaceutical products, polymers and fuel. A project to design a spiral coil, which is also called “pancake coil” for a given impeller and tank size involves the determination of the overall heat transfer coefficient, which is a function of the Nusselt (Nu), Reynolds (Re) and Prandtl ( ...

Results are presented from experimental investigations of heat transfer in a 25 mm I.D. copper tube, tightly fitted with helical-wire-coil inserts of varying pitch (p), helix angle (x) and wire diameter (e). A similarity law approach was attempted to interpret the friction and heat transfer results and correlate them in terms of roughness Reynolds number (h+), momentum transfer roughness function R(h+) and heat transfer roughness function G(h+, Pr). The present results are compared with previously published ...

Experimental studies have been carried out on isothermal pressure drop and convective heat transfer to servotherm medium grade oil in laminar flow in one smooth tube and seven wire coil-inserted tubes of varying wire diameter and pitch of wire coil. The performance of these wire coil inserted tubes has been evaluated by two different criteria based on the objective of either maximizing heat transfer rate or minimizing exchanger size. The results indicated that as much as fourfold improvement can ...

The thermal performance of these tubes was found to be superior compared to a smooth tube. Friction factors and heat transfer coefficients in these rough tubes were analysed on the basis of momentum and heat transfer analogy, ...

Apolipoprotein M (ApoM) is a 25-kDa HDL-associated apolipoprotein and a member of the lipocalin family of proteins. Mature apoM retains its signal peptide, which serves as a lipid anchor attaching apoM to the lipoproteins, thereby keeping it in the circulation. Studies in mice have suggested apoM to be antiatherogenic, but its physiological function is yet unknown. We have now determined the 1.95 Å resolution crystal structure of recombinant human apoM expressed in Escherichia coli and made the unexpected ...

We demonstrate a rapid method for enzyme immobilization directly on a waveguide surface by encapsulation in a silica matrix. Organophosphate hydrolase (OPH), an enzyme that catalytically hydrolyzes organophosphates, was used as a model enzyme to demonstrate the utility of lysozyme-mediated silica formation for enzyme stabilization. Silica morphology and the efficiency of OPH encapsulation were directly influenced by the precursor choice used in silica formation. Covalent attachment of the lysozyme ...

Abstract Ascorbic acid (AA) protects plants against abiotic stress. Previous studies suggested that this antioxidant is also involved in the control of flowering. To decipher how AA influences flowering time, we studied the four AA-deficient Arabidopsis (Arabidopsis thaliana) mutants vtc1-1, vtc2-1, vtc3-1, and vtc4-1 when grown under short and long days. These mutants flowered and senesced before the wild type irrespective of the photoperiod, a response that cannot simply be attributed to slightly ...

Today's proteome is the result of innumerous gene duplication, mutagenesis, drift and selection processes. Whereas random mutagenesis introduces predominantly only gradual changes in protein function, a case can be made that an abrupt switch in function caused by single amino acid substitutions will not only considerably further evolution but might constitute a prerequisite for the appearance of novel functionalities for which no promiscuous protein intermediates can be envisaged. Recently, tetracycline ...

Sensor histidine kinases of two-component signal-transduction systems are essential for bacteria to adapt to variable environmental conditions. However, despite their prevalence, it is not well understood how extracellular signals such as ligand binding regulate the activity of these sensor kinases. CitA is the sensor histidine kinase in Klebsiella pneumoniae that regulates the transport and anaerobic metabolism of citrate in response to its extracellular concentration. We report here the X-ray ...

The protein disulfide isomerase-related protein ERp29 is a putative chaperone involved in processing and secretion of secretory proteins. Until now, however, both the structure and the exact nature of interacting substrates remained unclear. We provide for the first time a crystal structure of human ERp29, refined to 2.9 A, and show that the protein has considerable structural homology to its Drosophila homolog Wind. We show that ERp29 binds directly not only to thyroglobulin and thyroglobulin-derived ...

This response correlates with heightened levels of salicylic acid (SA), which induces antimicrobial pathogenesis-related (PR) proteins. To determine if SA-mediated, enhanced disease resistance is a general phenomenon of AA deficiency, to elucidate the signal that stimulates SA synthesis, and to identify the biosynthetic pathway through which SA accumulates, ...

Independent lines of investigation have documented effects of both transposable elements (TEs) and gene length (GL) on gene expression. However, TE gene fractions are highly correlated with GL, suggesting that they cannot be considered independently. We evaluated the TE environment of human genes and GL jointly in an attempt to tease apart their relative effects. TE gene fractions and GL were compared with the overall level of gene expression and the breadth of expression across tissues. GL is strongly ...

The allosteric mechanism of one of the best characterized bacterial transcription regulators, tetracycline repressor (TetR), has recently been questioned. Tetracycline binding induces cooperative folding of TetR, as suggested by recent unfolding studies, rather than switching between two defined conformational states, namely a DNA-binding-competent conformation and a non-DNA-binding conformation. Upon ligand binding, a host of near-native multiconformational structures collapse into a single, highly ...
