Choice of an ordering strategy taking into account of risks about customer service levels and on-hands inventories

This paper investigates the foundations of cooperative identity and how it is constructed by the organisation. More specifically, our research focuses on a financial cooperative in the simultaneously emerging and consolidating cultural sector. The originality of this paper lies in the methodology used—textual analysis. We use the Economies of Worth model developed by Boltanski & Thévenot (2006), which accounts for a plurality of legitimate forms of evaluation used in the processes of critique and justification.GAME THEORY;SUPPLY CHAIN MANAGEMENT;DEICSION ANALYSIS;RISK ANALYSIS;SIMULATION

Catalyst-free Heteroepitaxy of III-V Semiconductor Nanowires on Silicon, Graphene, and Molybdenum Disulfide

The research presented in this dissertation pioneered three novel nano-material systems, including vertically aligned InAlAs nanowires (NWs) on two-dimensional (2-D) graphene, InAs NWs on 2-D MoS2, and GaAsP NWs on Si using metalorganic chemical vapor deposition (MOCVD). Bottom up integratiton of NW structures enable heteroepitaxy of largely dissimilar III-V compounds on foreign substrates and provide a basis for design of high-performance devices that are otherwise inaccessible using thin- films or planar geometries. During conventional heteroepitaxy of planar geometries, strict constraints are imposed by the need to match lattice parameters, thermal expansion coefficients, and polar coherence between adjacent dissimilar materials. Semiconductor III-V NWs with small substrate footprints can permit relief of lattice mismatch-induced strain in heteroepitaxial systems. Thus, high crystalline quality III-V compound semiconductor NWs can be monolithically integrated with foreign substrates for novel electronic and optoelectronic device designs. This dissertation presents wafer-scale production of vertically oriented InAsyP1-y and InxAl1-xAs NWs on single layer graphene (SLG) and MoS2 substrates, grown via pseudo-van der Waals epitaxy (vdWE). The morphology, areal density, and crystalstructure of InAsyP1-y NWs within the 1 ≤ y ≤ 0.8 range and InxAl1-xAs in the 1 ≤ x ≤ 0.5 range are quantitatively analyzed by mapping a wide growth parameter space as a function of growth temperature, V/III ratio, total precursor flow rate, and molar flow ratio of precursors. Furthermore, through manipulation of growth kinetics, selective-area vdWE of III-V NWs on 2-D MoS2 surfaces is demonstrated, and pattern-free positioning of single NWs on isolated MoS2 micro-plates with one-to-one NW-to-MoS2 placement is highlighted. Here, the highest axial growth rate of 840 nm/min and NW number density of ∼8.3 × 108 cm−2 for vdWE of high aspect ratio (\u3e80) InAs NW arrays on graphitic surfaces is reported. Additionally, selective-area epitaxy (SAE) of GaAsP-GaP core-multi shell NW arrays on patterned Si(111) substrates is reported. The composition of GaAsyP1-y NWs is tuned toward a targeted value of y = 0.73 to achieve the bandgap of 1.75 eV. The effect of growth rate on morphology, total yield, and symmetric yield of GaAsP NWs is explored through modulation of the effective local supply of growth species. Under the optimized SAE growth condition, \u3e 90% yield of hexagonally symmetric GaAsP NWs on Si is realized using a 100 μm × 100 μm field of nano-hole arrays in the center of a 400 μm × 400 μm mesa with border width of 100 μm

BIOLOGIJA RAZMNOŽAVANJA VRSTE Capoeta trutta (Heckel, 1843) U RIJECI SHOUR, JUGOZAPADNI IRAN

Reproductive characteristics of touyeni Capoeta trutta (Heckel, 1843), a native cyprinid in the Shour River, Iran, were investigated by monthly sampling between July 2010 and June 2011. Among 815 specimens captured, the overall sex ratio was 1:1.96 (males:females). Monthly changes of the gonado-somatic index (GSI) and frequency distribution of egg diameter confirmed that spawning lasted from January to April. Results indicated that the age at first maturity for males is one year and for females two years. Fecundity increased with fish age, averages being 2591 for 1+ old females and 11552 eggs in mature 6+ old females. Correlation of absolute fecundity and body weight was high (R= 0.85). The absolute fecundity between all age groups was statistically significant (p<0.05).Istraživanje reprodukcijskih osobina vrste Capoeta trutta (Heckel, 1843), izvornog ciprinida iz rijeke Shour u Iranu, vršeno je mjesečnim uzorkovanjem od srpnja 2010. do lipnja 2011. Između 815 ulovljenih primjeraka, ukupni omjer spolova bio je 1: 1,96 (mužjaci: ženke). Mjesečne promjene gonadosomatskog indeksa (GSI) i distribucije frekvencija promjera jaja ukazuju da je mrijest trajao od siječnja do travnja. Rezultat ukazuje da je dob prve spolne zrelosti za mužjake jedna godina, a kod ženki dvije godine. Plodnost se povećava s dobi i u prosjeku iznosi 2591 jaja za 1+ stare ženke te 11.552 jaja u zrelim ženkama kod dobi od 6+. Korelacija apsolutne plodnosti i tjelesne težine bila je visoka (R = 0,85). Apsolutna plodnost između svih dobnih skupina bila je statistički značajna (p <0,05)

Investigation on replacement of fish oil by vegetable oils (rice bran, soybean and linseed) in diet of rainbow trout (Oncorhynchus mykiss)

The aim of the present study was to determine the impact of replacing the fish oil by alternative lipid sources in diets for rainbow trout (Oncorhynchus mykiss) on growth, fatty acid profiles of muscle. Five isonitrogenous and isoenergetic semipurified diets were formulated containing 100% rice bran oil (RBO), 100% linseed oil (LO), 100% Soybean oil (SO) and a 1:1:1:1 rice bran, linseed, soybean and fish oil mixture (MX) were compared to a pure fish oil (FO) diet. The diets were fed to apparent satiation twice a day to triplicate groups of 30 rainbow trout with an initial weight of 90g for 15 weeks at 12°C.At the end of the experiment, fillet samples were collected from fish for the measurement of fatty acid profile and fillet composition. Fish fed the FO diet had the highest weight gain over the experimental period (280.28 g), However no differences in growth rate and CF were observed across diet groups. Feed conversion ratios (FCR) ranged from 1.12 to 1.24. Significant difference in FCR was found in the group fed an FO diet. The fillet lipid concentrations and fatty acid composition of the fish were significantly affected by the experimental diets. Fish fed the FO diet contained significantly lower lipid levels (20.18%) than those fed the 4 other diets. The highest level of n-3 PUFA concentrations were recorded in fish fed the LO diet (21.8) with significant difference than other diets and the lowest were in those fed the RBO diet (7.84). Fish fed the SO diet contained significantly higher level of n-6 PUFA concentrations (31.72) than other diets and the lowest were in those fed the FO diet (19.15). Fish on the FO diet had a significantly greater percentage of DHA (10.10%) in muscle tissue compared with fish on all other diets and the lowest was in those fed the RBO diet (2.81%). However, the highest level of eicosapentaenoic acid (EPA) concentrations was recorded in fish fed the SO diet (1.84%) and the lowest in those fed the diet (0.67%). This study showed considerable reductions (about 3-fold) in the n-3/n-6 ratio when FO in the fish diet was replaced by rice bran and soybean oils, which may be extremely negative from a nutritional point of view. In other hand linseed oil had the highest n-3/n-6 ratio (0.91) that was comparable with fish oil n- 3/n-6 ratio (0.89). The results in this study imply that an appropriate mix of vegetable oils and FO can replace the sole use of FO in fish feeds

Effect of sandblasting on the tensile bond strength of two permanent silicone soft liners to the denture base

Introduction: Soft liners are materials used in removable dental prostheses to maintain the health of inflamed mucous membranes. The materials bond strength to acrylic bases can be modified by several methods; One of which includes sandblasting. The aim of this study is to investigate the effect of sandblasting on the tensile bond strength(TBS) of two permanent silicone soft liners. Material & Methods: 36 dumbbell-shaped heat-cured polymethylmethacrylate acrylic specimens were fabricated in denture flasks with a length of 75 mm, width of 12 mm and a thickness of 7 mm in the thinnest section. 3 mm of the material of all specimens was cut using a low-speed diamond saw with water cooling. Then according to the surface treatment and sofliners, the specimens were divided into four groups: no surface treatment with mollosil softliner, no surface treatment with GC softliner, sandblasting with 50 μm Al2O3 particles and then using mollosil soft liner and sandblasting with 50 μm Al2O3 particles and then using GC soft liner. After polymerization of all specimens, TBS was evaluated with universal testing machine at a crosshead speed of 5 mm/min until failure. Finally, two-way ANOVA and independent T-test were used to analyzing the data. Results: The mean of TBS in the groups of sandblasting was significantly higher than other group and the mean of TBS in the group of mollosil was higher than GC group with or without sandblasting. (p=0.001) Conclusion: Sandblasting increases the TBS of silicone soft liners to the acrylic bases; moreover, Mollosil softliners are more tenacious compared to GC

Clustered two-dimensional mesh topology for large-scale network-on-chip architecture

Driven by the continuous scaling of Moore’s law, the number of processing cores in chip multiprocessors and systems-on-a-chip are expected to grow tremendously in the near future. Connecting the different components of a multiprocessor chip in a scalable and efficient way has become increasingly challenging. Current network-on-chip (NoC) topologies are adequate for small-size networks but are not optimized for large-scale networks. Transmitted packets inside a large NoC require longer route to reach their destinations, resulting in an increase in certain performance parameters such as latency and power consumption. Thus, it is necessary to develop a new topology appropriate for large-size NoCs. In this research, we proposed a cost-effective network topology for large-size NoCs that improves performance in terms of end-to-end latency. The topology, called RaMesh, consists of clusters of mesh networks. A routing algorithm suitable for this topology was also proposed. The RaMesh architecture together with mesh, torus, and clustered 2D-mesh were simulated using Noxim (NoC simulator), C for software NoC models, and Altera ModelSim for Verilog hardware models. Simulations were conducted under different network traffic and for a variety of network sizes. Experimental results showed that RaMesh performed better than equivalent 2D-mesh and torus topologies. RaMesh topology was also benchmarked against a clustered mesh topology. Average hop count in the proposed topology was at least 22.7% lower compared to the mesh and torus. Average latency was also decreased by at least 24.66% as compared to the mesh and torus. Finally, the saturation point for the proposed topology increased by at least 15% as compared to mesh and torus
