Supplier involvement in Collaborative Product Development Process

The need for supplier involvement in new product development process is going to be more intensive due to the increasing technology advances, product and technology complexity and the fast growth of international trade in today’s competitive markets. Therefore, firms have increased their collaboration with their suppliers in order to develop new products more effectively. However, this strategy influences the product development projects performance. Brown and Eisenhardt’s review on the previous studies in this research area reveals that though different factors and relations have been studied in supplier involvement in product development, the interactions among these factors are still incomprehensive [1]. Moreover, Takeishi has proposed an integrative framework for supplier involvement in product development in automobile industry [2]. In his framework, not only does he investigate automaker’s “internal capabilities” but also he includes “external coordination”, and their combined effect on component design quality as one of the main development performances. However, there are still some relationships among the OEM (Original Equipment Manufacturer) and its suppliers which have not been described clearly yet. This article concentrates on the three important factors which affect inter-firm product management process. These factors are (1) communication between OEM and its suppliers, (2) integrated problem solving, and (3) OEM’s degree of knowledge about the outsourced components. In addition, we investigate how these factors influence product development project performance criteria in terms of product quality, development time, and product innovation.
Evaluation of Meterorite Amono Acid Analysis Data Using Multivariate Techniques

The amino acid distributions in the Murchison carbonaceous chondrite, Mars meteorite ALH84001, and ice from the Allan Hills region of Antarctica re shown, using a multivariate technique known as Principal Component Analysis (PCA), to be statistically distinct (2.1-3.60) from the average amino acid compositions of 101 terrestrial protein superfamilies. The Allan Hills ice amino acid istribution clusters with those of ALH84001 samples, and is distinct (3 5 3 . 8 0 ) from the proteins. This indicates that contaminant biological amino acids in Antarctic ice have undergone fractionation in the geochemical environment. The several Murchison analyses examined have intracluster distances less than lo, suggesting that errestrial contamination in these samples is minimal. PCA accomplishes these discriminations using either raw amino acid distribution data or amino acid elemental composition. This work demonstrates that PCA and multivariate analysis in general can be usehl for the interpretation of possible biosignatures in extraterrestrial samples.
Comparative micro-Raman spectroscopy study of tellurium-filled double-walled carbon nanotubes

Tellurium-filled double-walled carbon nanotubes (Te@DWNTs) have been studied by Raman spectroscopy in the temperature interval from 300to700K employing 785nm excitation wavelength, and their spectra have been compared to those of pristine double-walled carbon nanotubes (DWNTs). The DWNTs were synthesized by catalytic chemical vapor deposition. Assignment of the radial breathing modes and the tangential modes was done based on the one dimensional electronic energy band structure of carbon nanotubes. The tangential mode components of Te@DWNT are downshifted compared to those of pristine DWNT consistent with the proposed weakening of the carbon-carbon bond due to the introduced van der Waals interaction of the Te atoms with the DWNT. It was established that Te@DWNT can be unambiguously identified by the 30% temperature coefficient decrease of the G′-band position.
Effect of ferric oxide nanoparticles on microtubules organization

Nanoparticles (NPs) are widely used in several manufactured products. The small size of nanoparticles facilitates­ their uptake into cells as well as transcytosis across epithelial cells into blood and lymph circulation to reach different sites, such as the central nervous system. Studies have shown different risks of Fe2O3NPs in the neuronal system and other organs. They are membrane-bound layer aggregates or single particles that could not enter only cells, but also in mitochondria and nuclei. Therefore­, these particles can interact with cytoplasmic proteins­ such as microtubules (MTs). MTs are cytoskeleton proteins that are essential in eukaryotic cells for a variety of functions, such as cellular transport, cell motility and mitosis. MTs play an important role in neurons and to act as a substances transport such as neurotransmitters. Single Fe2O3NPs in cytoplasm can interact­ with these proteins and affect their crucial functions­ in different­ tissues. In this study, we showed the effects of Fe2O3NPs on MTs organization and structure using ultraviolet spectrophotometer and fluorometry. The fluorescent spectroscopy­ showed a significant tubulin conformational­ change in the presence of Fe2O3NPs and the ultraviolet spectroscopy­ results showed that Fe2O3NPs causes MTs depolymerization and decrease turbidity intensity as well as increase spectra emission. The aim of this study was to find the potential risks that Fe2O3NPs pose to human organs and cells for cancer treatment. Key words: Ferric oxide, tubulin, microtubule, protein­ interaction, nanoparticle.
Catalytic Gasification of Pretreated Activated Sludge Supernatant in Near-critical Water

Pretreatment of waste activated sludge (WAS) and the subsequent near-critical water gasification (NCWG) is a potential avenue to convert WAS into value added products. Part one of the research investigated thermal and thermochemical pretreatments. No difference was observed in the percentage of sludge liquefied beyond 10min between 200°C to 300°C. It was found that pretreated activated sludge supernatant (PASS) doubled the gas yield compared to untreated sludge when gasified. The order of effectiveness for sludge treatment was thermo-alkali > thermal > thermo-acid for hydrogen production in NCWG. Part two investigated NCWG parameters to identify optimal conditions. High gasification yields were obtained using a commercial catalyst (Raney nickel), with hydrogen content of 65-75% of the gas phase products. Thermo-alkali treated PASS was found to perform well at subcritical temperatures with 25% higher yields than thermally treated PASS. Increased catalyst loading had little additional effect on gas yields above 0.075g.
Analysis Method of Stiffness and Load Capacity of Euler Spring with High Static Stiffness and Low Dynamic Stiffness

A large number of studies have shown that nonlinear passive control devices have good vibration attenuation and isolation effect. And vibration isolation systems with nonlinear stiffness have more advantages than linear systems. The paper addresses the stiffness and load capacity design problem of Euler springs with varying cross-sections. Firstly, in order to analyze nonlinear behavior of curved beams due to large geometric deformations, a set of first-order differential equations are established, which can be easily solved by numerical integration. Secondly, a curved beam is taken for example to compare analytical results calculated by using the first-order differential equations and ANSYS simulation results. Then the influence of geometric parameters of curved beams with varying cross-sections on structural stiffness and load capacity is investigated by using ANSYS. Finally, a design strategy for stiffness and load capacity of curved beams is summed up.
Source to sink relations between the Tian Shan and Junggar Basin (northwest China) from Late Palaeozoic to Quaternary: evidence from detrital U‐Pb zircon geochronology

The tectonic evolution of the Tian Shan, as for most ranges in continental Asia is dominated by north‐south compression since the Cenozoic India‐Asia collision. However, precollision governing tectonic processes remain enigmatic. An excellent record is provided by thick Palaeozoic – Cenozoic lacustrine to fluvial depositional sequences that are well preserved in the southern margin of the Junggar Basin and exposed along a foreland basin associated to the Late Cenozoic rejuvenation of the Tian Shan ranges. U/Pb (LA‐ICP‐MS) dating of detrital zircons from 14 sandstone samples from a continuous series ranging in age from latest Palaeozoic to Quaternary is used to investigate changes in sediment provenance through time and to correlate them with major tectonic phases in the range. Samples were systematically collected along two nearby sections in the foreland basin. The results show that the detrital zircons are mostly magmatic in origin, with some minor input from metamorphic zircons. The U‐Pb detrital zircon ages range widely from 127 to 2856 Ma and can be divided into four main groups: 127–197 (sub‐peak at 159 Ma), 250–379 (sub‐peak at 318 Ma), 381–538 (sub‐peak at 406 Ma) and 543–2856 Ma (sub‐peak at 912 Ma). These groups indicate that the zircons were largely derived from the Tian Shan area to the south since a Late Carboniferous basin initiation. The provenance and basin‐range pattern evolution of the southern margin of Junggar Basin can be generally divided into four stages: (1) Late Carboniferous – Early Triassic basin evolution in a half‐graben or post‐orogenic extensional context; (2) From Middle Triassic to Upper Jurassic times, the southern Junggar became a passively subsiding basin until (3) being inverted during Lower Cretaceous – Palaeogene; (4) During the Neogene, a piedmont developed along the northern margin of the North Tian Shan block and Junggar Basin became a true foreland basin.
Catalogues of radial and rotational velocities of 1253 F–K dwarfs in 13 nearby open clusters

Context. We conducted a long-term monitoring of solar-type dwarfs in 13 nearby open clusters, d < 500 pc, over 19 years, but most individual radial velocities were never published, apart from a small number of spectroscopic binaries. Aims. Our program was designed to study membership and duplicity, and to search for new cluster members.
Альтернативные убиквитин-конъюгирующие ферменты Е2 регулируют эндоцитоз рецептора интерферона-1 Endocytosis of the IFNAR1 chain of Type 1 interferon receptor is regulated by diverse E2 ubiquitin conjugation enzymes

Ubiquitination of signaling receptors triggers their endocytosis to restrict the extent of cell signaling. Type 1 interferon (IFN1) eliminates its receptor from cell surface via stimulating the ubiquitination of its IFNAR1 chain. While it was suggested that this ubiquitination aids IFNAR1 internalization via relieving a steric hindrance of a linear motif within IFNAR1 from the endocytic machinery, the mechanisms involved remain poorly understood. Here we describe a specific role for two disparate ubiquitin acceptor sites within this receptor. These sites, Lys501 and Lys525 / 526, exhibit a preference for polyubiquitination via either Lys63- or Lys48-linked chains (K63-Ub and K48-Ub, re-spectively). Whereas the SCF β Trcp E3 ubiquitin ligase controls either type of ubiquitination-dependent IFNAR1 endocytosis, the specificity of these processes is determined by two different E2 ubiquitin conjugating enzymes, Ubc13 and Cdc34. These enzymes can be directly used by SCF β Trcp E3 ubiquitin ligase to generate either K63-Ub or K48-Ub in vitro. Ubc13 is involved in IFNAR1 endocytosis driven by the K63-Ub modification of Lys501, whereas the K48-Ub-specific Cdc34 affects receptor endocytosis via ubiquitin conjugation that occurs on Lys525 / 526. Both types of linkages combine to maximize IFNAR1 endocytosis otherwise suppressed by unfavorable conformation dependent on the presence of a conserved Pro470 within the intracellular domain of IFNAR1. We propose a model where alternate utilization of both E2s to assemble diverse polyubiquitin linkages cooperates to achieve IFNAR1 intracellular domain conformations and spatial arrangements that favor a maximal rate of receptor endocytosis.
The Strengthening Effect of Tantalum in Nickel-Base Superalloys

The strengthening effect of tantalum in nickel-base superalloy (B1900) has been systematically investigated. Tantalum not only raises high temperature tensile strength and creep resistance but also obviously improves ductility in high temperature tensile and stress rupture tests. About 70-80% of the tantalum in the alloy enters the Y' phase, about 15% Ta forms MC type tantalum-containing carbide, the remainder is dissolved in the Ymatrix. The beneficial effect of tantalum not only results from enhanced Y' strengthening, but also by solid solution strengthening, and simultaneously the improvement of structural stability at high temperature during long time exposure. Tantalum can also improve thermal fatigue and marine-gas corrosion resistances. Considering strength effects, it may be possible to substitute Nb for Ta.
Effect of Coloured Agro-Net Covers on Insect Pest Control and Yield of Tomato (Solanum lycopersicon Mill)

Tomato ( Solanum lycopersicon Mill) is one of the most important vegetable crops consumed throughout the world; and is rich in important vitamins, minerals and antioxidants. Production of the crop in open fields is however constrained by several biotic and abiotic stresses that lead to low tomato yields and quality. This study aimed at determining the effects of coloured agro-net covers on microclimate, pest infestation and yield of tomato cultivar ‘‘Rio Grande’’. The study consisted of two trials conducted using a randomized complete block design (RCBD) with five replications and six treatments. Tomato plants were grown under blue, yellow, grey, white or multi-coloured net covers with a no net cover as the control. Data were collected on microclimate (temperature, soil moisture, relative humidity and photosynthetically active radiation), pest counts and crop yield variables. Net covering modified the tomato crop microclimate with highest temperatures and soil moisture and, relative humidity levels recorded under white (21.03 o C), blue (30.03%) and multi-coloured net covers (76.26%), respectively compared to the no net control treatment (16.32 o C, 14.82% and 64.90%). Photosynthetically active radiation (PAR) was lowest under the blue agro-net cover (416.09 µmol m -2 s -1 ) and highest under control treatment (985.00 µmol m -2 s -1 ). Tomato plants grown under coloured-colour nets (yellow and blue) had lower population of silverleaf whitefly, thrips and aphids while mite population was lower under neutral-colour net covers (white, grey and multi-coloured). The neutral-colour net covers (24938.87, 19525.16 and 21541.93 kg/ha) resulted in higher yields compared to coloured-colour net covers (16804.62 and 14551.05 kg/ha). Results of the study indicate that use of agro-net covers especially the neutral-colour net cover can improve microclimate, protect tomato against insect pests and can be considered a viable strategy for tomato production by smallholder growers.

Testing the efficacy of different substances against Arion slugs (Arionidae) under laboratory conditions

In 2008 and 2009 we studied molluscicidal activity of 26 substances in 89 different treatments under laboratory conditions. The experiments in which slugs (Arion spp.) were a part took place in two series: 1) with the injection of active substances in slug intestines; and 2) with the application of pellets. After giving the injection we observed 100% mortality of slugs in treatments with Bacillus thuringiensis var. kurstaki (0.25 ml in 10% concentration/individual), caffeine (0.25 ml in 10% concentration/individual), sodium dodecyl sulphate (0.25 ml in 10% concentration/individual, 0.125 ml in 10% concentration/individual, 0.125 ml in 5% concentration/individual, 0.0625 ml in 10% concentration/individual), and pirimicarb (0.25 ml in 10% concentration/individual, 0.125 ml in 10% concentration/individual, 0.125 ml in 5% concentration/individual, 0.0625 ml in 10% concentration/individual). Meanwhile, the application of pellets resulted in the highest (100%) slug mortality when sodium dodecyl sulphate in 0.5% concentration with caraway as a supplement was used.
Anomalously Slow Electron Transfer at Ordered Graphite Electrodes: Influence of Electronic Factors and Reactive Sites

Electron-transfer rates for 17 inorganic redox systems plus methyl viologen were determined on highly ordered pyrolytic graphite (HOPG) and glassy carbon (GC). Provided the HOPG defect density is low, the electrontransfer rates of all systems are much slower on the basal plane of HOPG than on GC. The slow rates on HOPG show a trend with the homogenous self-exchange rate constants, but in all cases the HOPG rate constants are substantially lower than that calculated via Marcus theory from self-exchange rates. The low HOPG rates do not exhibit any trends with redox system charge or E1/2, as might be expected in the presence of double-layer or hydrophobic effects. The results are consistent with the semimetal properties of HOPG, which have been invoked to explain its low interfacial capacitance. Both the density of electronic states (DOS) and carrier density for HOPG are much lower than those for metals. By analogy to theories developed for electron transfer at semiconductor electrodes, the rate depends on an effectively bimolecular reaction between the redox system and carriers in the electrode. The low DOS and carrier density of HOPG leads to low electron-transfer rates compared to those of metals, or to those predicted from exchange rates. Disorder in the graphite increases electron-transfer rates and the DOS, thus yielding much faster rates on both GC and defective HOPG. For the 14 outer-sphere systems studied here, this electronic factor is much more important than any interaction with specific surface sites present at defects. The evidence indicates that, for Fe(CN)i3I4, Eu:tJt3, Fet2It3, and V:l/+3, specific surface interactions provide inner-sphere routes which have a large effect on the observed rate constant. aq
The cultural consistence of built heritage constitutes its intangible dimension

Monuments and sites will only constitute outstanding examples of mankind’s genius if, to the aesthetic qualities of a know-how developed by different peoples, we add the perception of a cultural value that makes them unique and inter-relatable with a universal sense, in their historicity as well as in their authenticity. Revealing itself as fundamental to the self-identity of inhabitants and of places, the intangible dimension has to contain the recognition of its comprehension applied to a material support, which is specific to each heritage. Through examples as different as a baroque palace in Malta, the rescue of an ancient Portuguese church in Bangladesh or cooperation efforts being made in Indonesia to safeguard part of an ancient city-palace, we intend to highlight the importance of the immaterial values that justify the need to safeguard built heritage.
An Energy-efficient MAC Protocol for Wireless Body Area Networks

A WBAN node may be working in two monitoring modes, all-transmit mode and few-transmit mode. Every mode has its own usage scenarios. To effectively prolong its lifetime, a node should be working in few-transmit mode as much as possible. An adaptive medium access control (MAC) protocol is specially designed to serve the nodes working in few-transmit mode. Experimental results show the proposed MAC protocol can improve the energy efficiency and satisfy the data delivery delay demands simultaneously.
Mother's Time with Children: Does Time Matter?

Author(s): Hsin, Amy | Abstract: Despite the theoretical importance mother’s time with children plays in the literature on children’s intellectual development, few studies have identified a significant relationship between the time children spend with mothers and their cognitive outcomes. This study uses children’s time diaries from the Child Development Supplement of the Panel Study of Income Dynamics to investigate the effect of the quantity and intensity of maternal care during early childhood on children’s later cognitive test scores (N = 1,008). Results show that the time mothers spend with children is positively correlated with verbal scores for children with verbally skilled mothers and that the influence of early maternal care has a persistent effect on later test scores even after lagged tests are controlled. The intensity of care or the percentage of total care devoted to active engagement is positively associated with development of analytic skills for children with skilled mothers. The findings suggest that children of mothers with better verbal skills benefit the most from spending more time with mothers. The findings also suggest that children can acquire verbal skills through passive interaction with verbally skilled mothers as well as through active interactions. On the other hand, the development of analytical skills may require more intense and direct involvement. Taken together, the results point to time use as a means of social reproduction—time with children is a pathway though which highly skilled mothers impart their human capital to their children.
Review paper The interaction of coronary microembolization and ischemic preconditioning: A third window of cardioprotection through TNF-alpha

With an unstable atherosclerotic coronary plaque, episodes of myocardial ischemia associated with release of debris and microembolization and subsequent restoration of more or less sufficient coronary blood flow can precede ultimate plaque rupture, complete coronary occlusion and impending acute myocardial infarction. Such scenario involves both coronary microembolization with its established detrimental consequences for the dependent myocardium and repeated, transient episodes of myocardial ischemia/reperfusion which can induce protection by ischemic preconditioning. The current review aims to study the interaction between these adverse and beneficial effects. Experimental coronary microembolization in anesthetized pigs does not induce nor prevent acute preconditioning against infarction. However, six hours after coronary microembolization a third window of protection exists, which results from the upregulation of TNF-alpha. Apparently, TNF-alpha exerts bidirectional effects, i.e. induces contractile dysfunction but protects from infarction.
