The volatiles released byMicromonospora aurantiacawere collected by means of a closed-loop stripping apparatus (CLSA) and analysed by GC–MS. The headspace extracts contained more than 90 compounds from different classes. Fatty acid methyl esters (FAMEs) comprised the major compound class including saturated unbranched, monomethyl and dimethyl branched FAMEs in diverse structural variants: Unbranched, α-branched, γ-branched, (ω−1)-branched, (ω−2)-branched, α- and (ω−1)-branched, γ- and (ω−1)-branched, γ- and (ω−2)-branched, and γ- and (ω−3)-branched FAMEs.

Abstract:
Abstract Most fatty acids (FAs) are straight chains and are synthesized by fatty acid synthase (FASN) using acetyl-CoA and malonyl-CoA units. Yet, FASN is known to be promiscuous as it may use methylmalonyl-CoA instead of malonyl-CoA and thereby introduce methyl-branches. We have recently found that the cytosolic enzyme ECHDC1 degrades ethylmalonyl-CoA and methylmalonyl-CoA, which presumably result from promiscuous reactions catalyzed by acetyl-CoA carboxylase on butyryl- and propionyl-CoA. Here, we tested the hypothesis that ECHDC1 is a metabolite repair enzyme that serves to prevent the form

Abstract:
Acetylenic acids are isomerized by alkali metal amides of 1,3-diaminopropane to 3,5-dienoic acids. An acid with a methyl branch at C-3 separating the carboxyl from the triple bond is rearranged to a mixture of the terminal alkynoic acid and two isomeric 3,5-dienoic acids. The corresponding 4-methyl compound affords the terminal alkynoic acid, one 3,5-dienoic acid, and two cyclized products, cis- and trans-3-methyl-5-(octylidene)-1-cyclopentanecarboxylic acids. Propargylic acids branched at C-5 and C-6 are rearranged to the appropriately substituted 3,5-dienoic acids in moderate yield.

From the results of DSC and XRD, the introduction of methyl group successfully destroys the crystallizability of the PBAm chains, thus making it become a relative soft segment compare

The methylation index of branched tetraethers (MBT) and cyclization ratio of branched tetraethers (CBT) based on the distribution of branched glycerol dialkyl glycerol tetraethers (brGDGT) are useful proxies for the reconstruction of mean annual air temperature (MAT) and soil pH. Recently, a series of 6-methyl brGDGTs were identified which were previously co-eluted with 5-methyl brGDGTs. However, little is known about 6-methyl brGDGTs in the Qinghai–Tibetan Plateau (QTP), a critical region of the global climate system. Here, we analyze 30 surface soils covering a large area of the QT

Abstract:
We introduce a very simple but efficient idea for branch & bound (B&B) algorithms in global optimization (GO). As input for our generic algorithm, we need an upper bound algorithm for the GO maximization problem and a branching rule. The latter reduces the problem into several smaller subproblems of the same type. The new B&B approach delivers one global optimizer or, if stopped before finished, improved upper and lower bounds for the problem. Its main difference to commonly used B&B techniques is its ability to approximate the problem from above and from below while traversing the problem tre

In this article a new branch & bound method is described. It uses an artificial target to improve its bounding capabilities. Therefore the new approach is faster compared to the classical one. It is applied to the stochastic problem of optimal scenario tree reduction. The aspects of global optimization are emphasized here. All necessary components for that problem are developed and some experimental results underline the benefits of the new approach.

Abstract: Lignocellulosic and waste from the food industry offers a sustainable way to produce alternative transportation fuel and provide fiber and biomaterial. Thermochemical processes can depolymerize lignin into its phenolic monomers which can be upgraded to aromatic hydrocarbons. Fatty acids from food wastes have functional groups to accommodate selective synthesis of chemicals. These characteristics could be utilized as sustainable high-value additive products for fuels and lubricating oils. In the present study, an effective lubricity additive was synthesized via continuous alkylation o

Abstract:
There is currently a sustained interest in biofuels as they represent a potential alternative to petroleum derived fuels. Biofuels are likely to help decrease greenhouse gases emissions and the dependence on oil resources. Biodiesels are Fatty Acid Methyl Esters (FAMEs) that are mainly derived from vegetable oils; their compositions depend from the parent vegetables: rapeseed (“RME”), soybean (“SME”), sunflower, palm etc. A fraction of biodiesel has also an animal origin (“tallow”). A key factor for the use of biofuels in gas turbines is their Emissions Indices (NOx, CO, VOC, PM) in comparison

Abstract:
An important requirement in the design of an inlet duct of a turboprop engine is the ability to provide foreign object damage protection. A possible method for providing this protection is to include a bypass branch duct as an integral part of the main inlet duct. This arrangement would divert ingested debris away from the engine through the bypass. However, such an arrangement could raise the possibility of separated flow in the inlet, which in turn can increase pressure losses if not properly accounted for during the design.

Abstract:
In a search for compounds that can enhance tissue-type plasminogen activator (t-PA) synthesis in cultured human endothelial cells we found that dibutyryl cyclic AMP (at a concentration of 2 mM) led to a several-fold increase in t-PA production by endothelial cells over a 24 h incubation period. Further researchshowed that this stimulating effectcould be explained by the slow liberation of butyrate, as the effect could be reproduced by addition of free butyrate to the medium, but notby addition of 8-bromo cyclic AMP. With butyrate, an accelerated accumulation of t-PA antigen in the conditioned

Spatio-temporal video grounding aims to retrieve the spatio-temporal tube of a queried object according to the given sentence. Currently, most existing grounding methods are restricted to well-aligned segment-sentence pairs. In this paper, we explore spatio-temporal video grounding on unaligned data and multi-form sentences. This challenging task requires to capture critical object relations to identify the queried target. However, existing approaches cannot distinguish notable objects and remain in ineffective relation modeling between unnecessary objects. Thus, we propose a novel object-awar

Our study was designed to elucidate the chemical determinants of pectin cross-linking in developing fruits of apple and peach and to evaluate the role of breakage cross-linkages in swelling, softening, and cell separation during the ripening. Peaches cell walls soften and swell considerably during the ripening, whereas apples fruit cells maintain wall firmness but cells separate during late stages of ripening. We used a "double-reduction" technique to show that levels of non-methyl esters of polyuronic acid molecules were constant during the development and ripening and decreased only in overr

Abstract:
There are a number of applications where the attachment of hot tap fittings to in-service pipelines by welding is difficult, if not impossible. These applications include very thin-wall pipelines, older carbon steel pipelines with very high carbon equivalent values, pipelines made of high-alloy materials, sub-sea pipelines, etc. There are two primary concerns with welding onto in-service pipelines and piping systems. The first concern is for welder safety during welding, since there is a risk of burnthrough, where the welding arc causes the pipe wall to be penetrated allowing the contents to e
