The SIMP approach is one of the most frequently used methods for topology optimization of structures. In this method, the relative density is expressed as a function of coordinates and varies from 0 to 1 within the design domain. Relative densities of 0 and 1 are associated to the existence and non-existence of the material, respectively. The finite element approach is usually utilized to analy...

The postharvest life of cut Eustoma grandiflorum flowers is limited in open flowers. Therefore a factorial experiment based on a completely randomized design with ascorbic acid (AsA) at 4 levels (0, 100, 200, 300mg L-1) and citric acid (CA) at 3 levels (0, 100, 200 mg L-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. Results indicated that a significa...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...

We determine the relative pion mass shift Mπ(L)/Mπ − 1 due to the finite spatial extent L of the box by means of two-flavor chiral perturbation theory and the one-particle Lüscher formula. We use as input the expression for the infinite volume ππ forward scattering amplitude up to next-to-next-to-leading order and can therefore control the convergence of the chiral series. A comparison to the f...

Different theories of bodily tides assume different forms of dependence of the angular lag 8 upon the tidal frequency %. In the old theory (Gerstenkorn 1955, MacDonald 1964, Kaula 1964) the geometric lag angle is assumed constant (i.e., 8 ~ x), while the new theory (Singer 1968; Mignard 1979, 1980) postulates constancy of the time lag At (which is equivalent to saying that 8 ~ j} ). Each partic...

The drying of hydrogel films formed by poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) block copolymers (Pluronic P105 and Pluronic L64) is investigated at various air relative humidity (RH) conditions in the range 11-94%. These amphiphilic block copolymers self-assemble to form a variety of ordered (lyotropic liquid crystalline) structures as the water content decreases. The amount of wat...

Soil and rhizosphere environments were examined in order to determine the identity and relative abundance of bacteria that catabolize d- and l-amino acids as the sole source of carbon and nitrogen. All substrates were readily catabolized by bacteria from both environments, with most d-amino acids giving similar CFU counts to their l-amino acid counterparts. CFU count ratios between l- and d-ami...

Aeroponic culture is an alternative method for optimizing growth of different plants in controlled conditions. Aeroponic systems are an efficient tool for the root studies and improving medicinal root production. In order to study the feasibility of valerian (Valeriana officinalis L.) production in aeroponic systems and assessing the effects of different NAA concentrations (0, 0.1, 0.3, and 0.5...

Recently researchers have shown interest in integrating Reconfigurable logic into conventional processors as a Reconfigurable Function Unit (RFU). A context-full RFU supports holding intermediate results inside itself, which eliminates some data movement overheads and has some other benefits. Most contemporary processors support out-of-order execution and speculation. When a context-full RFU is...
