Profitable working capital management in industrial maintenance companies

Purpose – The purpose of this paper is to analyze the impact of working capital management on profitability in industrial maintenance service companies. Design/methodology/approach – Analytical modeling has been used as the research method. Finnish industrial maintenance companies have been analyzed on the basis of their financial statements. Findings – We reveal a significant negative correlation between the cycle times of operational working capital and the return on investment of industrial maintenance companies. Light fixed assets and good profitability of the maintenance sector emphasize the importance of working capital management. Large maintenance service companies seem to achieve competitive advantage over small and medium sized maintenance service providers through both fixed assets- and working capital-related economies of scale, and through the fact that large maintenance service providers often focus on providing services mostly for their host companies. Research limitations – The scarcity of large enterprises in the market in question precludes the use of a more extensive sample in the analysis. Practical implications – In the industrial maintenance service business, more attention should be paid to active management of working capital. We can conclude that this holds true especially in large industrial maintenance service enterprises. Originality/value – We contribute to the unexplored perspective of industrial maintenance companies. Previous studies of industrial maintenance companies have not addressed working capital management, which gains more and more attention under the volatile economic circumstances of the present day. Keywords - Industrial maintenance services, Profitability, Working capital, Flexible asset management model Paper type - Research pape

Total Synthesis of Marine Glycosphingolipid Vesparioside B

The first total synthesis of a major component of marine glycolipid vesparioside B (Scheme , <b>1</b>, R₁ = <i>n</i>-C₂₂H₄₅, R₂ = <i>n</i>-C₁₄H₂₉) has been accomplished through a convergent [4 + 3] coupling strategy. Key steps included stereoselective installment of a set of challenging 1,2-<i>cis</i>-glycoside bonds. A 2-quinolinecarbonyl-assisted α-galactosylation and a novel β-arabinosylation were developed, respectively, to synthesize the α-galactofuranosidic and the β-arabinopyranosidic linkages. Furthermore, a 4,6-<i>O</i>-benzylidene-controlled α-galactopyranosylation reaction allowed the efficient connection of the left tetrasaccharide donor <b>2</b> with the right disaccharide lipid acceptor <b>3</b>, hence leading to the total synthesis of <b>1</b>

Exploiting spacetime symmetry in dissipative nonlinear multimode amplifiers for output control

Time-reversal symmetry enables shaping input waves to control output waves in many linear and nonlinear systems; however energy dissipation violates such symmetry. We consider a saturated multimode fiber amplifier in which light generates heat flow and suffers nonlinear thermo-optical scattering, breaking time-reversal symmetry. We identify a spacetime symmetry which maps the target output back to an input field. This mapping employs phase conjugation, gain and absorption substitution but not time reversal, and holds in steady-state and for slowly varying inputs. Our results open the possibility of output control of a saturated multimode fiber amplifier

DataSheet_1_Light influences the effect of exogenous ethylene on the phenolic composition of Cabernet Sauvignon grapes.docx

The gaseous phytohormone ethylene (ETH) plays a key role in plant growth and development, and is a major regulator of phenolic biosynthesis. Light has long been known to influence phytohormone signaling transduction. However, whether light influences the effect of ETH on the phenolic composition of grapes (Vitis vinifera L.) is an open question. Here, the accumulation and composition of anthocyanins and non-anthocyanin phenolics were analyzed in Cabernet Sauvignon grapes under four treatments: light exposure with and without ETH treatment, and box-shading with and without ETH treatment. Both light and ETH promoted ripening, decreased the color index (L*, C*, and h*), and accelerated the color change from green to red and purplish red. Sunlight-exposed grapes had the highest contents of most anthocyanins, flavonols, flavan-3-ols, and hydroxybenzoic acids. In addition, light exposure increased the ratios of 3’5’-substituted/3’-substituted anthocyanins and flavonols, but decreased the ratios of methoxylated/non-methoxylated and acylated/non-acylated anthocyanins and flavan-3-ols. Notably, the effects of ETH were influenced by light exposure. Specifically, ETH treatment promoted anthocyanin and non-anthocyanin biosynthesis in light-exposed grapes, and their increasing multiples were remarkably higher under light-exposed conditions. Furthermore, ETH treatment decreased the ratios of methoxylated/non-methoxylated, 3’5’-substituted/3’-substituted, and acylated/non-acylated anthocyanins and flavan-3-ols in light-exposed grapes, each of which was increased by ETH treatment in shaded grapes. Fifteen differential phenolic components were identified through partial least-squares-discriminant analysis (PLS-DA). Among them, cyanidin-3-O-(cis-6-O-coumaryl)-glucoside, petunidin-3-O-(6-O-acetyl)-glucoside, petunidin-3-O-(trans-6-O-coumaryl)-glucoside, petunidin-3-O-glucoside, myricetin-3-O-galactoside, kaempferol-3-O-galactoside, and kaempferol-3-O-glucoside were the main differential components between ETH treatments under different light conditions. This study contributes to the understanding of the impact of ethylene treatment under dark and light conditions on phenolic synthesis in grape berries.</p
