The structure of β-DL-methionine, C5H11NO2S, in the space groupC2/c, is here confirmed to be fully ordered all the way up to the phase transition at approximately 326 K, where displacive sliding of molecular bilayers gives the disorderedP21/cα form [data at 340 K; Görbitz (2014).Acta Cryst.E70, 341–343]. The geometry of hydrogen bonds in LD–LD hydrogen-bonding patterns [Görbitzet al.(2009).Acta Cryst.B65, 393–400] at the hydrophilic core of each molecular bilayer are virtually unperturbed by the phase shift, but the C—C—S—C torsion angle of the side chain changes fromtransat 320 K togauche+ fo

Abstract:
Leech neurons in culture sprout rapidly when attached to extracts from connective tissue surrounding the nervous system. Laminin-like molecules that promote sprouting have now been isolated from this extracellular matrix. Two mAbs have been prepared that react on immunoblots with a approximately equal to 220- and a approximately equal to 340-kD polypeptide, respectively. These antibodies have been used to purify molecules with cross-shaped structures in the electron microscope. The molecules, of approximately equal to 10(3) kD on nonreducing SDS gels, have subunits of approximately equal to 34

Abstract:
Under low nutrient conditions hyphae of certain fungi are strongly attracted to microcolonies of bacteria belonging to the genera Pseudomonas and Agrobacterium. Hyphae of the fungi penetrate the microcolonies and proliferate to produce coral-loid, haustorial-like masses of absorptive hyphae. The bacteria in the colonies are lysed and the contents apparently absorbed as a nutrient source by the fungi. The four fungi that demonstrated this capability were Agaricus brunnescens (= A. bisporus), Coprinus quadrifidus, Lepista nuda, and Pleurotus ostreatus. Approximately 100 additional species belong

Air pollution is a challenge for municipal authorities. Increased emission of PM10 and PM 2.5 particles is particularly noticeable in Poland primarily the autumn and winter period. That is due to the start of the heating season. According to the above data, road transport accounted for approximately 5% of the creation of PM10 particles, ca. 7% of PM2.5 and approximately 32% for NOx. In Poland, suspended particles (PM10 and PM2.5) cause deaths of as many as 45,000 people a year. The issue of smog also affects other European cities.

We coined the terms immediate and delayed apoptosis to help distinguish the mechanistic differences between apoptosis and programmed cell death (or delayed apoptosis) which have been incorrectly used as synonyms. This confusion occurred primarily because these two cell death mechanisms are morphologically identical. However, k

This thesis presents an empirical investigation into the Arbitrage Pricing Theory (APT).

The first line of investigation examines the effect of the assumed nature of the form of the return generating process of stocks. It is found that stocks follow an approximate factor structure and tests of the APT are sensitive to the specified form of the return generating process.

In predicting corrosivity, it is therefore important to measure the corrosion behaviour under controlled flowing conditions in environments that simulate as closely as possible those expected in an oil refinery.

Abstract:
Abstract Stress corrosion crack (SCC) growth rate tests were conducted on sensitized and non-sensitized stainless steels (Type 304, 304L) cold worked to levels between 18 and 28%. Compact tension specimens were actively loaded to a stress intensity factor of approximately 38 MPa√m and exposed to high temperature, high purity water at 360°C under constant load conditions. Specimens were also ring loaded to a K level of approximately 35 MPa√m and exposed to high temperature high purity water at 338°C. SCC was observed in every specimen test with the exception of the 304L specimen cold worked 18%

Abstract:
Abstract Frequent leaks were observed in the seal flush coolers of pumps in crude distillation unit where shell side is open recirculation cooling water. These coolers are in small size and low value items. However, repeated coil leaks resulted in failure of pump seals (increased maintenance cost) &amp; reduced standby redundancy of the pumps. Moreover, cooling water is often contaminated with hydrocarbon (seal oil media) causing increased wastage of treated water by blowdowns (environmental concern), additional consumption of fresh water &amp; treatment chemicals.

Full text
Abstract:
Abstract Corrosion Under Insulation (CUI) is widely acknowledged to be a critical issue facing plant operators in the oil, gas and chemical industries. CUI studies from a petrochemical facility have shown that 40-60% of pipe maintenance costs are due to CUI and approximately 10% of the total maintenance budget is spent repairing damage from CUI, mainly on pipes. The risk of corrosion under insulation is considered high in the temperature range 50 – 175°C (122 – 347°F) and extreme when in cyclic temperature service between -20 and 320°C (-4 – 608°F). Periodic inspection remains the best way to

Abstract:
Polybenzoxazine, a high-perfomance phenolic resin, was used as a precursor for carbon aerogel electrode of supercapacitors. A cost-effective ambient drying was used for benzoxazine aerogel preparation. After the pyrolysis of benzoxazine aerogel under a nitrogen atmosphere, carbon aerogel was obtained. The BET surface area of the carbon aerogel was approximately 360 m2/g. The activation of the carbon aerogels was also investigated in order to compare the physical and electrochemical properties. The BET surface area of the activated carbon aerogels increased more than twice in comparison with th

Full text
Abstract:
High-low misalignment in girth welds introduces local bending stress and thus can potentially have detrimental effects on the load capacity of girth welds. However, long-term pipeline service experience demonstrates that pipelines can survive a large degree of high-low misalignment without an appreciably negative impact on the safety and integrity of the pipeline. This project is intended to understand the effects of misalignment on the performance of girth welds. Under Phase 1 (preceding phase) of this project, the effect of weld high-low misalignment on nominally defect-free girth welds was

Abstract:
A reciprocating compressor facility with seven to eight compressors could be expected on average to develop new leakage at standard components of 2,700 Mcf/yr. Approximately 75% of the total new leak volume occurs at compressor components even though they only comprise approximately 30% of the total components at a site. The cost of follow-up surveys can be reduced by focusing on the compressor areas. A centrifugal compressor facility with two compressors could be expected to develop new leakage at standard components of approximately 100 Mcf/yr. The results are indicative of the fact that the

Abstract:
Transportation agencies in northern environments spend a considerable amount of their budget on salt for winter operations. For example, in the state of Indiana, there are approximately 120 salt storage facilities distributed throughout the state and the state expends between 30 M USD and 60 M USD on inventory and delivery each year. Historical techniques of relying on visual estimates of salt stockpiles can be inaccurate and unhelpful for managing the supply chain during the winter or planning for re-supply during the summer months.

This paper exploits a rich collection of household surveys to investigate the wage differential between the public and private sectors in 17 Latin American countries during the 1980s and 1990s. The paper also studies how the sector of employment affects the gender wage gap. The paper finds very small premia for male workers and significant premia for female workers. The paper also finds that, on average, Latin American women earn 30 percent less than men with similar skills and that approximately one third of this gender gap results from lack of access to formal sector employment.

There were two main objectives of this research. The first objective was to verify SINTEFs' pipe/soil interaction model test results, on which the A.G.A. Level 2 and 3 soil models are based. The second objective was to quantify the amount of conservatives built into the model equations for stiffer clay soils (above 30 psf shear strength). The original testing (at SINTEF) was done in soft clay soils (30 psf), and extrapolations to stiffer soils were done very conservatively, because data was not available. To accomplish these two objectives, pipe-soil interaction model tests were conducted at T
